|Adam Zanation||Otolaryngology Head & Neck Surgeryemail@example.com||Outcomes and Genomics in Head/Neck, Transoral Robotic and Skull Base Surgery||Head and neck tumors are a diverse group of neoplasms that are typically treated with surgery, radiation and chemotherapy. Surgery in the standard fashion has a number of swallowing, breathing and speaking deficients that can occur. Novel surgical approach such as endoscopic resection and robotic resections are reducing surgical morbidity. My research goals include studying novel surgical techniques for tumor outcomes, quality of life, cost and complications. Also, since my practice involves a significant number of orphan tumors, the study of the genomics of these tumors is important for future treatment options and treatment stratification.|
|Adam Zanation||Otolaryngology Head & Neck Surgeryfirstname.lastname@example.org||Outcomes and quality of life research for head and neck neoplasms||The goal of the my research interests include clinical, neurocognitive and quality of life outcomes in head and neck tumor surgery and skull base surgery. My Skull Base Oncology fellowship and my current practice emphasize minimally invasive surgical techniques and I have actively published on both technical advancements and prospective outcomes research in the area of endoscopic skull base surgery. My current clinical research involves hypothesis driven prospective trials on tumor related outcomes but also cost and indirect health outcomes such as quality of life, neurocognitive outcomes, and olfactory/cranial nerve functional outcomes. I also have a clinical interest in studying the impact of multidisciplinary care (such as interactive tumor boards and combined inter-specialty clinics) on treatment planning. My translational research involves genomic analysis of rare skull base tumors and salivary tumors for future therapeutic targets.|

|Ajay Gulati||Pediatricsfirstname.lastname@example.org||Microbial influences in inflammatory bowel diseases||My lab is interested in developing safer therapies for the treatment of children with inflammatory bowel diseases (IBD). Presently, most medications used to treat these patients rely on suppression of the immune system and have a high potential for side effects. However, the immune system is only one of the factors that drives intestinal inflammation in IBD. Both the gut microbiota (the normal bacteria that live in our gut) and the intestinal epithelium can modulate host inflammatory responses. One cell type that lies at the intersection of the gut microbiota and the intestinal epithelium is the Paneth cell. These are intestinal epithelial cells that secrete natural antibiotics known as antimicrobial peptides (AMPs). AMPs, in turn, are able to modulate gut bacterial communities. Our overarching hypothesis is that augmenting Paneth cell function will help control gut bacterial communities to reduce chronic intestinal inflammation. To test this hypothesis, we utilize specimens from 2 sources: 1) Genetically-engineered mice that are susceptible to intestinal inflammation; and 2) Tissue and stool specimens from children with IBD. Interestingly, we have found that both susceptible mice, and IBD patients have Paneth cell abnormalities that our lab is in the process of characterizing. We expect this work will lead to novel, minimally-toxic therapies for IBD.|
|Alice Ammerman||Nutritionemail@example.com||Nutrition and physical activity for obesity/chronic disease prevention in underserved communities. Local food systems and food access.||Design and testing of innovative clinical and community-based nutrition and physical activity intervention approaches for chronic disease risk reduction in primarily low income and minority populations. Dr. Ammerman has strong research and practice collaborations across the state addressing childhood obesity and was appointed by the Lieutenant Governor to serve on the Childhood Obesity Study Committee, charged with recommending legislative action around childhood obesity. She is also PI of the Center of Excellence for Training and Research Translation, charged with identification, translation, and dissemination of evidence-based interventions for obesity and cardiovascular disease control and prevention. More recent research interests focus on school nutrition policy associated with childhood obesity, sustainable agriculture as it relates to improved nutrition, and social entrepreneurship as a sustainable approach to addressing public health concerns.|
|Alice Chuang||Obstetrics & Gynecologyfirstname.lastname@example.org||Analysis of maternal obesity with delayed delivery of the fetus in the setting of cesarean section for nonreassuring fetal status||A common indication for cesarean section is concern for fetal status that arises during intrapartum fetal heart rate monitoring. Delays to delivery in this setting are associated with increased risk of fetal hypoxic acidemia. There are many reasons to believe obese women are at higher risk for longer delivery intervals. It is our goal to see if there are delays in obese women and how they contribute to neonatal complications. (as summarized by Dr. Warshak)
This study stems from the \"Obesity Cohort Trial\" IRB 20123231.
The PI is Dr. Carri Warshak at the University of Cincinnati. I am serving as a local administrator and mentor.
|Alison Stuebe||Obstetrics & Gynecologyemail@example.com||The psychobiology of pregnancy, lactation, and mother-infant attachment||My research focuses on mechanisms of maternal-infant interaction, with an emphasis on lactation and postpartum depression. In the Mood, Mother and Infant study, we are quantifying the role of oxytocin and HPA-axis dysregulation in postpartum depression and impaired mother-infant attachment. Our hypothesis is that PPD is associated with reduced oxytocin and maternal HPA axis dysregulation. These changes reduce maternal sensitivity, impairing dyadic development and increasing risk for insecure attachment. Participants join the study in the third trimester of pregnancy, and mothers and infants present for lab visits at 2, 6 and 12 months postpartum. Medical students have the opportunity to participate in study visits at the MotherInfant Biobehavioral Lab, working with mothers and infants to collect biological samples, heart rate variability data, and videotaped mother-infant interactions.|
|Amir H Khandani||Radiologyfirstname.lastname@example.org||PET Imaging||I am an expert in positron emission tomography (PET). My research interests lie in understanding the basic principles of PET imaging with various radiotracers such as FDG (radioactive glucose) or FLT (radioactive thymidine), what their uptake in the cell means and how the information can be translated to the disease process.|
|Amy Weil||General Mediicine & Clinical Epidemiologyemail@example.com||Projects involving depression in primary care, humanism in medical education and intimate partner violence||Currently we are reviewing and improving our Depression Screening and Treatment Program in our Internal Medicine Clinic and are working on projects to do so, leading to publication, including developing an anxiety screening and treatment program. We have also recently added a psychiatrist consultant and will be looking at how she assists us with complex patients.
I am currently working to expand humanities education for medical students and there may be opportunity to develop programs/analyze reflective writing pieces leading to publication.
Finally, we are working on initiatives to improve our detection of both depression and intimate partner violence in our Latino clinic.
A later project may involve detection of human trafficking victims in Latino clinic and elsewhere in our hospital and community.
|Amy Shaheen||Internal Med-General firstname.lastname@example.org||quality and safety in primary care||The quality of care that one receives is variable. Some of the determinants of health include race, gender, socioeconomic status and education. Unfortunately, sometimes it also depends on where and by whom one gets care. Even within our system we see huge variations in care. I have been working for the last few years on decreasing variation in primary care. We have done that in a number of ways, including establishing registries, developing electronic health alerts, and engaging in quality improvement work. Some of the recent projects with which I have been involved include studying the variation of care in benzodiazepine and narcotic prescribing in the UNC IM clinic, decreasing variation of care in acute low back pain, and reducing variation in the pre-authorization process.
While quality improvement research is not new, our understanding of what makes a project sustainable is less so. The current project will look at factors that determine a sustainable project in 10 practices. The project will involve surveying participants, evaluating QI data, and creating a checklist to be passed to the next group working on a QI project in the practice. While \"hand-off documents\" have been used for patient care, they have not been tried for QI. The study will involve identifying key elements and getting feedback from participants. We will also have access to the QI data through the primary care collaborative for the practices where the participants will do their QI work. This data will help determine success of the projects.
|Andrew Wang||Radiation Oncology Nanomedicineemail@example.com||Nano-and Translational Medicine||My research focuses on applying advances in nanotechnology and biomedical engineering to oncology. Our current research directions are (1) utilizing nanoparticle therapeutics to improve chemoradiotherapy treatment of cancer, (2) tissue engineer ex vivo liver and lung metastases for cancer research studies.
Nanomedicine is a relatively new branch of science that holds high potential in improving the treatment of many diseases, including cancer. Nanoparticles preferentially accumulate in tumors and there is high interest in developing nanoparticle drugs for cancer treatment. There are many nanoparticle drugs in clinical development. My lab develops novel formulations of nanoparticle drugs and evaluate them in animal models of cancer. We also work with commercial formulations (from companies) to obtain the preclinical data for future early phase clinical trials. Our work is very translational and innovative. We have filed 3 patents in the last two years.
Our other research direction is to engineer ex vivo models of cancer metastasis. We collaborate with Dr. Lola Reid and have developed a new liver metastasis model.
I am looking for hardworking students who want to challenge themselves with cutting edge science. Hardwork will be rewarded with co-authorship on manuscripts.
|Andrew Wang||Radiation Oncology Nanomedicine||translational||no||zawang@med,unc.edu||Developing nanoparticle-based chemotherapeutics and tissue engineering colorectal cancer liver metastasis||My laboratory aims to translate technological advances in engineering to novel cancer diagnostics and therapeutics. We have two major research directions. First, we are interested in the development of nanoparticle-based chemotherapeutics to improve chemoradiotherapy and systemic treatment of GI cancers. We formulate our own nanoparticles and compare them to commercial small molecules in mouse models of cancer. We also collaborate with Drs. Joseph DeSimone, Wenbin Lin and Leaf Huang to take advantage of their nanoparticle platforms. The second research direction in our laboratory involves applying advances in tissue engineering to developing an ex vivo (in vitro) 3D model of liver metastasis. Using decellularized liver we tissue, we have generated 3D colonies of colorectal cancer cell lines. We are in the process of characterizing these colonies and evaluation their potential for clinical application.|
|Andrey Bortsov||Anesthesiologyfirstname.lastname@example.org||Genetics and epigenetics of post-traumatic pain||We employ a variety of computational and statistical approaches to identify genetic and epigenetic predictors of chronic musculoskeletal pain after trauma.

|Andy Kiser||Surgeryfirstname.lastname@example.org||Fluid shifts during myocardial ablation||There is early clinical evidence that fluid shifts which occur during endocardial and epicardial ablation of myocardium for the treatment of atrial fibrillation are greater than expected. Evaluation of weight gain, net fluid balance, and serum oncotic markers may contribute to our understanding of these fluid shifts. Further, a better understanding of these clinical findings may lead us to a better understanding of the influence atrial naturetic peptide (ANP) may have.
My research initially is the clinical examination and comparison of patients undergoing independent and concomitant endocardial and epicardial myocardial ablation. Further, through the collection and examination of human cardiac tissue and by evaluation of serum markers, we may better be able to identify the contribution of ANP to fluid retention and, perhaps, heart failure.
|Anna Cuomo||Orthopedics||clinical||no||Anna_cuomo@med.unc.edu||Prospective, observational study on postoperative pain medication use in children following orthopedic trauma surgery: are we prescribing too much ?||This will be a prospective, observational cohort study to determine how much pain medication is being used by children following surgical treatment of common pediatric fractures. The common practice amongst surgeons is to prescribe at least a week supply of narcotic pain medication for children after surgery, however, it is the author\'s experience that most children require only one or two days of medication and most do not require narcotics. We plan to enroll patients immediately after their surgery and follow them with phone calls at home during the first postoperative week to determine their pain levels and pain medication requirements. We hope to better understand postoperative pain in this cohort and offer surgeons better guidelines for prescribing narcotics.|
|Anne Mounsey||Family Medicineemail@example.com||Learner Driven Education||Background: This is a proof-of-concept project designed to assess whether a specific educational intervention is associated with improved knowledge of important clinical topics. The intervention is a simulated mobile app that identifies key questions (but not answers) about clinical topics and encourages users to research answers on their own. The simulated app also collects data on frequency and duration of use.
Project Requirements: The summer research student will join the project at a key point when we are transitioning from the pilot phase to the formal trial phase of the project, and will be expected to contribute to:
- collection of qualitative feedback from pilot participants
- preparation of a poster/presentation describing pilot outcomes
- final design of the simulated appâ€™s look and feel
- design of data summary tables and reports
- design of the orientation for subjects in the trial phase
What we offer: During this summer research experience, the student will have the opportunity to learn about:
design and implementation of randomized, controlled trials, especially of educational interventions
web-based survey design and distribution using Qualtrics
collation and summarization of qualitative and quantitative data
presentation of research results through oral presentations, posters, and in written form
|Anne Peery||Gastroenterology & Hepatologyfirstname.lastname@example.org||Signs and Symptoms of Acute Uncomplicated Diverticulitis||Acute uncomplicated diverticulitis (AUD) is an intestinal condition characterized by inflammation of one or more colonic diverticula without abscess or gross perforation. Patients with AUD present with acute onset of moderate to severe abdominal pain, profound malaise, fever and anorexia. Episodes are associated with worse quality of life and work and activity impairments. Annually in the United States (U.S.), there are 2,000,000 clinic visits and 200,000 hospital admissions for acute diverticulitis. Diverticular disease is one of the most costly gastrointestinal diseases at $2.5 billion dollars per year.
There is urgent clinical trial work to be done to better define the appropriate use of antibiotics in AUD. There is no evidence that patients with AUD benefit from antibiotics and antibiotics are associated with significant risk, from potentially life-threatening complications to emerging bacterial resistance. Before trials can be done, research is needed to determine the appropriate inclusion criteria for AUD. While CT scan confirmation is the gold standard for a diagnosis whether or not a patient might also need to have a fever or leukocytosis is debatable and if required could severely limit trial enrollment.
The specific aim of this proposed summer project is to retrospectively assess whether patients with abdominal pain and CT confirmed AUD also typically present with leukocytosis or fever. I hypothesize that leukocytosis and fever in this population is rare and are not necessary for inclusion in a clinical trial of AUD.
|Anne Steiner||Obstetrics & Gynecologyemail@example.com||Physical Activity and Conception||Physical Activity and Conception is an on-going research study designed to examine the association between physical activity and implantation success following in vitro fertilization. The project has 2 specific aims: 1) To determine the association between acute physical activity and implantation success and 2) To determine the association between past year physical activity and implantation success. Women undergoing in vitro fertilization are enrolled in this study. They complete a questionnaire including questions on demographics and past year physical activity. Following embryo transfer, women keep a daily diary and wear an accelerometer (an objective device to assess physical activity) until their scheduled pregnancy test. The accelerometer provides a precise measure of physical activity. Implantation success is defined as a positive pregnancy test. I am an NIH funded researcher and fertility specialist. My research focus is reproductive epidemiology. This project is a collaborative project between myself and Kelly Evenson in the Department of Epidemiology in the School of Public Health. This project is suitable for a short term research experience because it will allow the student to have a better understanding of research ethics and clinical research implementation including recruitment, consent process, enrollment, medical record abstraction, and data entry. She will learn about study design, data analysis, and data presentation.|
|Anthony Charles||Surgeryfirstname.lastname@example.org||Predictors of Mortality and other outcome measures in Trauma Patients||The purpose of this study is to ascertain risk factors for death from trauma. The large cohort allows for simultaneous evaluation of known mortality risk factors along with controlling for factors to assess the influence of each independently. Individually, base deficit, temperature, hypotension, age, and injury severity have been shown to be associated with an increased risk of death. However, in the English literature, there is no data on the independent predictive power and interaction of these risk factors.
Other outcome measures we are studying include, Hospital Length of stay, Intensive care unit length of stay. discharge destination and complications
In addition, as we have an aging population we are proposing to look at the influence of pre-existing cormorbid diseases on trauma outcome using the Charlson Co-morbidity Index.
The state of North Carolina has a developed trauma system, with hospitals with varying trauma verifications and capabilities. We are interested in the mortality effect of direct transportation of a trauma victim to a trauma center as opposed to transfer to the nearest hospital.
Data sources available for use include: National Trauma Data Bank (NTDB), North Carolina Trauma Registry and the University of North Carolina Trauma Registry.

|Balfour Sartor||Gastroenterology & Hepatologyemail@example.com||Host/Microbial interactions in intestinal inflammation and homeostasis||The major focus of Dr. Sartor`s laboratory is to better define the role of commensal enteric bacteria in mediating immune-mediated chronic intestinal inflammation vs. mucosal homeostasis in genetically susceptible vs. resistant hosts, respectively. This research employs gnotobiotic rodent models in which the enteric bacteria can be precisely manipulated, using the National Gnotobiotic Rodent Resource Center (P40 RR018603) that he directs. Primary models are IL-10 deficient mice colonized with E. coli and Enterococcus faecalis and isogenic mutants of these species in which various bacterial virulence genes have been deleted to determine their functional role (RO1 DK 53347) and HLA B27/Ã¯Â¢2 microglobulin transgenic rats colonized with Bacteroides vulgatus and other Bacteroides species (RO1 DK40249). In vitro mechanistic studies complement these in vivo investigations. These investigations explore both host and bacterial factors that mediate inflammation vs. homeostasis, particularly host immunoregulation and commensal bacterial virulence genes and the effect of inflammation on bacterial gene expression. Additional funded studies investigate the mechanisms by which diet, particularly dietary iron, aluminum and sucrose, potentiates experimental intestinal inflammation, exploring the effect of dietary components on enteric bacterial composition and gene expression (Crohn`s and Colitis Foundation of America Senior Research Award), the role of dietary iron on Bacteroides fragilis function (R21 AI079183), the role of enteric bacteria and bacterial TLR ligands on hepatic fibrosis and neoplasia (RO1 DK 076920), the therapeutic potential of probiotic bacterial species on hepatic inflammation and fibrosis (R21 AT003878) and the role of enteric bacteria and bacterial components on radiation-induced intestinal injury (U19 AI 067798).|

|Benny Joyner, Jr.||Anesthesiologyfirstname.lastname@example.org||Investigating health literacy level of communications between physicians and patients in teh Emergency Department||My research has spanned the range of clinical and basic sciences. Initially, my research focused on pulmonary pathophysiology especially as it related to chronic conditions such as asthma and acute injury secondary to inhalation injury. While I still remain engaged in research as it relates to pulmonary pathophysiology, my interests have transitioned to more of an interest in systems-issues within the clinical arena-patient safety, communication among providers and communication between providers and patients. Currently, I have two ongoing projects examining the different factors that comprise the physician patient interaction in the hopes of identifying specific aspects of communication that can be targeted for intervention. The hope in initiating the proposed project with Mr. Robert Wiggins is that we can examine one component of the interaction with families, the level of literacy that physicians (specifically Emergency Medicine physicians) use when communicating discharge plans with their patients. We will attempt to demonstrate a relationship between literacy level of physician communication and rate of emergency room re-visits (i.e.-the more complex/higher the level of literacy of the discharge instructions the higher the rate of emergency room re-visits).|

|Boyce Griffith||Otherfirstname.lastname@example.org||Computer modeling and simulation of cardiovascular function and dysfunction||Our research focuses on mathematical modeling and computer simulation of cardiovascular function and dysfunction. Research topics include fundamental research on methods to enable physiological simulation, tools for medical image-based model construction, and applications in physiological simulation. This research falls within the scope of mathematical and computational biomedical engineering. We are actively working to develop computer simulation-based tools for modeling medical devices. For instance, with UNC clinicians, we are actively developing computer models of transcatheter aortic valve replacement (TAVR) devices that can assist in device selection and device design. We envision that similar models will also be developed for emerging transcatheter devices for mitral valve repair and replacement. We are also developing computer models of cardiac electro-mechanical coupling that can be applied to cardiac resynchronization therapy (CRT). Finally, we are beginning work in collaboration with researchers at the FDA to simulate the performance of vena cava filters, prosthetic heart valves, and ventricular assist devices. We aim to demonstrate that our simulation tools are capable of providing regulatory grade evidence for a range of cardiovascular devices. Doing so will require careful validation using both in vitro and in vivo models.|
|Brian Button||Medicineemail@example.com||The Biophysics of Mucus Hydration and Adhesion/Cohesion||The goal of my research is understanding how altered mucus properties, including increased mucus adhesion and mucus cohesively, are responsible for slowed mucus clearance rates in persons with chronic bronchitis and cystic fibrosis. To address these questions, we utilize novel approaches which, for the first time, directly quantify the adhesive/cohesive strength of the mucus to the airway surface. As a model system, we utilize both an in vitro cell culture models of the human airway, as well as freshly excised tissue from chronic bronchitic and cystic fibrosis lungs. Finally, from a therapeutics point of view, we are actively testing the effect of several putative rehydrating and mucolytic agents on reducing mucus adhesion, and thus, stimulating clearance. As a physiologist with a background in airway epithelia, my research has been evolved with understanding various aspects of mucus clearance. As a biomedical engineer, my focus has to design, construct, and implement a number of unique experimental devices to measure the various properties of the mucus-cell interactions. Overall my work represents a culmination of this work to provide measures of the adhesive/cohesive strength of mucus in airway disease. Long-term, the goal of this work is the development of these approaches as biomarkers for the severity of lung disease and as a measure of therapeutic efficacy.|

|Celia Shiau||Otheremail@example.com||Function and development of brain microglia and other tissue macrophages||Development and function of tissue-resident macrophages
Macrophages are highly dynamic and widespread blood cells that play many important functions in vertebrates. They are the main phagocytes throughout the body, responsible for clearing away dying cells, damaged tissue, and pathogens, to maintain tissue integrity. Macrophages circulate in the bloodstream as monocytes or are stationed in strategic locations of the body as tissue macrophages where their phagocytic roles are critical, such as microglia in the brain, Kupffer cells in the liver, Langerhans cells in the skin, and osteoclasts in the bone. Overall, the developmental process by which macrophages take residence and differentiate into tissue macrophages remains poorly understood. We are currently investigating the transcriptional and cellular regulation underpinning the differentiation of the diverse tissue macrophages.
Cell-cell interactions between macrophages and other systems
The influence of macrophages on the development and homeostasis of various organs can be far-reaching. Yet the normal roles and mechanisms of macrophages and microglia in the healthy body and brain, respectively, remain far less understood than their functions in disease and injury. Of particular interest is the function of microglia in the healthy brain. Although not well understood, they have been implicated in shaping brain circuitry and neuronal development as well as in possibly affecting behavioral outcomes. We are also focusing on the critical role of macrophages in preventing inappropriate activation of inflammatory processes that would otherwise damage healthy tissues. We are addressing fundamental areas of macrophage biology in the context of how macrophages participate in the nervous system as well as other areas of the body prone to inflammation.

Past research experiences allow me to appreciate the complexity of the illness and the process has transformed me from a quantitative researcher into one who starts to appreciate the philosophical underpinnings of qualitative research. The most recent research project that I am working on is a community-based participatory research study, which intends to explore the subjective experiences of activity participation -or participation restriction- in people with schizophrenia who live in the community. A theoretical framework is expected to be yielded to describe any common patterns in these people`s experiences, associated subjective feelings, influencing factors, and impact on well-being. A measurement tool on activity participation for this patient group will be developed based on the resultant theory, followed by an intervention program for facilitating activity participation in the community.|
|Chris Dekaney||Otheremail@example.com||Mechanisms and Function of Paneth Cell Expansion After Doxorubicin-Induced Damage||While the intestinal epithelium has a remarkable capacity to repair and regenerate after injury, our understanding of underlying mechanisms of epithelial repair is incomplete. Intestinal stem cells (ISC) play a central role in repair of intestinal epithelium following damage and are under the influence of numerous factors which make up the ISC niche such as Paneth cells (PC) which reside at the base of small intestinal crypts intercalated among ISCs. This places PCs in an advantageous position to influence ISCs impacting survival, proliferation or cell fate decisions during epithelial repair. We recently reported dramatic PC expansion, associated with ISC expansion, in mice following intestinal epithelial injury by the commonly used chemotherapeutic drug, doxorubicin (Dox). Students involved in this project will take part in defining the mechanisms and mediators of PC expansion and the functional significance of PC expansion on enteric microbiota and ISC expansion following the damaging effects of chemotherapy on the intestinal epithelium. Students will be exposed to molecular biology (PCR, protein electrophoresis), histology and morphometry, cell culture, and flow cytometry.|
|Chris Mack||Pathology & Laboratory Medicinefirstname.lastname@example.org||Vascular disease and hypertension||Although we are interested in many areas of cardiovascular physiology and pathophysiology, much of our work revolves around the question of how changes in gene expression in vascular smooth muscle affect the development of cardiovascular disease. Major projects include;
1)The genetics of hypertension â€“ With the help of our clinical and bioinformatic colleagues, we generate and analyze genetic, gene expression, and clinical data sets to identify the mechanisms by which common genetic variations control vessel contraction, blood pressure, and the development of hypertension.
2)The epigenetic regulation of contractile gene expression in vascular smooth muscle â€“ We use a variety of genome-wide approaches to identify the enhancer elements, transcription factors, and chromatin modifiers that drive the SMC-specific expression of many contractile genes.
3)Cytoskeletal and contractile signaling in vascular smooth muscle â€“ We continue to characterize the RhoA-mediated signaling mechanisms that control actin polymerization, actin-myosin-based force generation, and myocardin factor nuclear localization in smooth muscle.
|Chris Dekaney||Surgeryemail@example.com||Role of Paneth Cells in damage repair.||Paneth cells make up part of the intestinal stem cell niche. Following damage we observe that the number and size of Paneth cells within this niche increase during regeneration concomitant with intestinal stem cell expansion. This lead us to ask why this increase in Paneth cells occurs and how this increase occurs. To these ends, we are investigating the roles Paneth cells play in intestinal regeneration and the mechanism(s) involved in expansion of the Paneth cells during repair. Understanding these areas will allow us to have a better understanding of the intestinal stem cell niche during repair, but will also provide us with valuable insight in how to control Paneth cell numbers and potentially Paneth cell secretory products. Participation in this project will provide students with exposure to molecular biology, histology, cell culture, microscopy, proteomics and data analysis.|
|Christian Jobin||Gastroenterology & Hepatologyfirstname.lastname@example.org||Host bacteria interaction in health and diseases||The intestine poses an interesting conundrum. It must peacefully cohabit with a sea of commensal bacteria (~100 trillion) and a high load of bacterial products but swiftly respond to the presence of pathogenic microorganisms that threaten its integrity. This task is especially challenging due to the presence of an abundant and complex lymphoid intestinal system and a high number of immune cells. A major clinical consequence of deregulated bacteria/host interaction in the intestine is the development of inflammatory bowel diseases (IBD). In addition, a serious medical complication for patients suffering from IBD is the development of colitis-associated colon cancer. As a product of our co-evolution with bacteria, a communication system has developed that allow us to regulate one another and to maintain homeostasis in the face of this potentially highly antigenic milieu. An integral part of this communication system is performed by innate bacterial sensors known as pattern recognition receptors (PRRs). Two main classes of PRRs have been shown to regulate communication between the intestinal epithelium and the microbiota. Toll-like receptors (TLRs) and Nod-like receptors (NLRs) serve to alert the host to the presence of bacteria in the extracellular and intracellular spaces respectively. The long-term goal of our research is to define the molecular mechanism regulating bacteria/host interaction in the intestine. Using mice housed in germ-free conditions and tissue specific gene deleted mice (immune and epithelial specific deletion), we study the cellular contribution of TLR- and NLR-derived signaling on bacteria-induced colitis, intestinal injury (ischemia/reperfusion) and colitis-associated colon cancer.|
|Christine Kistler||Family Medicine||clinical||no||Christine_Kistler@med.unc.edu||Urinary Tract Infections in Nursing homes||\'m looking to conduct a summer project from late May/start of June through the first week of August examining the work-up for urinalysis and urine cultures in 4 NHs in Central North Carolina. The goal is to get preliminary data for the development of a risk calculator for UTI in nursing home patients. We will be going to the sites and doing chart reviews at the 4 sites once a month over the course of the summer. Each NH may require two days to do the chart reviews, depending on the number of U/As and cultures done. The project includes chart review, data collection, and data entry. I will provide mentorship through the process and the student will be assisted in submitting an abstract for AGS and co-authoring a manuscript.
In general I conduct work on clinical decision making around the care of older adults. I have focused primarily on preventive services such as cancer screening and immunizations, but also am working on e-cigarettes and antibiotic use.
|Christine Khandelwal||Family Medicineemail@example.com||The Elder And Caregiversâ€™ Health (TEACH) Group Visits for the management of dementia and caregiver issues||Overall Objective of Study: To determine if The Elder And Caregiversâ€™ Health (TEACH) Group Visits for the management of dementia can be a suitable model for delivering ongoing, problem-focused medical care for patients with dementia and their caregivers. The study aim is to assess not only the direct effect of participation in TEACH Group Visits for the management of dementia, but equally to assess the feasibility of study design, including the feasibility of administering caregiver support and patient care in a group clinic setting, and assessing the primary care provider knowledge in dementia quality indicators.
The Project: TEACH Group Visits will be developed and implemented in an outpatient academic clinical setting. The program format will be adapted from previous work on group visits for management of chronic conditions, including dementia (University of Washington). The content of visits will be structured on a chronic care model for dementia developed at the University of Washington Memory Disorders Clinic around four key domains: dementia as a brain disease process, behavioral and psychiatric symptoms, medical co-morbidities, and caregiver and psychosocial issues which will include advanced care directives and future planning.
Students Role: Student will learn about group visits in a primary care setting, gain a basic understanding of dementia and caregiver issues, learn to use health literacy concepts and how to apply them with educational material. A student will begin looking over at the observational data and interpreting dementia and depression screening tests to begin manuscript writing for the pilot. We have been invited by Dr. Soo Borson to present our work to her to be posted on the Innovations Exchange, HHS.gov website. The student will be involved in this process. This is to serve as a forum of sharing information on this concept involving group visits with caregivers. Also, based on final feedback from participants, the student will play a role in revising the TEACH Group Visits manuscript and they will help finalize a product. The student will have an opportunity to remain involved the next year at a one year mark to join with us in a follow up visit and the possibility of participating in these group visits in another clinical site.
|Claire Doerschuk||Pulmonary & Critical Care Medicinefirstname.lastname@example.org||Leucocyte function in pneumonia, acute lung injury and tobacco-related lung disease||Dr. Doerschuk\'s research interests address host defense mechanisms in the lungs, particularly the inflammatory and innate immune processes that are important in the pathogenesis and course of bacterial pneumonia and acute lung injury/acute respiratory distress syndrome. Basic and translational studies address the mechanisms of host defense during pneumonia in response to pathogens that cause common and clinically important community-acquired and nosocomial pneumonias. Her focus is in the mechanisms of leukocyte recruitment and function, particularly neutrophils and macrophages, neutrophil-endothelial cell interactions, and effector functions of neutrophils during inflammation and innate immune responses in the lungs. Studies of leukocyte kinetics include neutrophil production and release from the bone marrow and their sequestration, adhesion and migration into lung tissue. More recently, her studies address leukocyte kinetics, immune responses and host defense in chronic obstructive pulmonary disease, both chronic bronchitis and emphysema. A mouse model of tobacco product-induced lung disease facilitates studies of the immune response to smoke from combustible cigarettes, little cigars and cigarillos. The ultimate goal is to utilize this knowledge to develop therapies that enhance the inflammatory response when it is beneficial to the host and dampen this response when it is harmful.|

We have identified stem cell sub-populations from both the liver and pancreas that can potentially differentiate to mature cells. By integrating novel technologies from the area of tissue engineering we have placed an emphasis on developing the matrix or template that would support the growth and differentiation of selected stem cell populations into functional tissues. This effort is impacted to factors including ischemia-reperfusion as it relates to cell recovery, proliferation and differentiation. A complementary arm of our experiments includes the study of the immune responses as they potentially affect the development of these novel organs-tissues.

|Deborah Love||Social Medicinefirstname.lastname@example.org||Pilot study to describe the methods and processes for discussing, documenting, retrieving and interpreting advance care plans for adult inpatients at UNC Healthcare||Care at end of life for hospitalized patients often fails to affirm patient values and preferences; yet the primary means for capturing and documenting patient preferences â€“ advance directives (ADs) â€“ appears to have several pitfalls. What is not clear is whether ADs and other means of advance care planning are inherently flawed. We hypothesize that they are rendered less effective by flawed processes used for creating, documenting and retrieving them â€“ particularly in the inpatient setting. Furthermore, it is probable that these process defects are compounded by knowledge and skills gaps on the part of clinicians and staff involved in discussing and interpreting advance care plans.
This is a mixed methods study that includes qualitative interviews with clinicians and staff involved in the discussion, documentation, retrieval, and interpretation of advance care plans. In addition data from the CDW will be used to examine AD incidence in admitted patients and decedents during a one-year period. Finally, a sample of decedent medical records will be examined to determine how patient expressions of advance care plans are discussed, documented and honored in care provided at end of life. The review of decedent medical records will be conducted in the summer of 2014 and offers substantial opportunity for framing issues related to concordance between patient wishes and care provided. Mentoring from Dept of Social Med. faculty with clinical ethics interests and background will be offered.

Even Charles Darwin wrote about it in his treatise The Expression of the Emotions in Man and Animals. At Duke, our laboratory takes a multidisciplinary approach to understand how stimuli in the gut affect our brains and behavior.
We recently discovered that, like taste cells in the tongue, the gut has a sensory neuroepithelial circuit (The New Yorker - Listening to the brain below). This circuit may be the point of integration of signals from food, bacteria, or viruses in the gut and behaviors in the brain.
We study the behaviors, neural links, and cells connecting the gut and the brain. These connections are at the core of disorders such as autism, anorexia, depression, irritable bowel syndrome, and inflammatory bowel disease.

Both insulin resistance and pancreatic ÃŸ-cell dysfunction are present early in the development of T2DM, but hyperglycemia (i.e. diabetes mellitus) does not develop without ÃŸ-cell dysfunction. Insulin secretion is a complex process initiated by nutrient secretagogues, including glucose and fatty acids (FA).

We are testing this hypothesis by examining how disrupted primary cilia signaling affects the formation and function of neuronal circuitry, dysfunction of which is widely implicated in the pathophysiology of neurodevelopmental disorders. We employ a powerful combination of mouse genetics, electrophysiology, in vivo live cell imaging, behavioral assays, and chemogenetic manipulation of ciliary signaling to decipher the convergent mechanisms underlying neuronal connectivity. By determining the changes in cortical neuronal connectivity and function following primary cilia dysfunction, in the context of patient mutations in ciliary genes associated with neurodevelopmental disorders, the outcome of these studies will help pinpoint the signaling pathways highly relevant to circuit malformations in neurodevelopmental disorders.|

|Frank Church||Hematology & Oncologyemail@example.com||Contribution of Senescence to the Age-Associated Risk of Venous Thromboembolism||Thrombosis is a life-threatening condition affecting thousands of men and women in the United States each year. The risk of venous thrombosis or venous thromboembolism (VTE) increases as we age, although the precise mechanism is not known. Expression of the tumor-suppressor gene p16ink4a (p16) increases with age and is associated with cellular senescence. However, it is not known if p16 is involved in the relationship between aging, senescence and the increased risk of venous thrombosis. We are testing a hypothesis that senescence (and aging) is associated with impaired hemostasis and will contribute to a prothrombotic phenotype. We are performing several different studies: (a) transgenic mouse model of p16 over-expression has a mild prothrombotic phenotype; (b) aged mice (1.5-2 years old) naturally up-regulate p16 expression and show age-related senescence; (c) in vitro model of human endothelial cell expression that become senescent (with several compounds used in drug-coated stents that promote localized cellular senescence); and (d) we would like to gather translational data regarding p16 expression linked to the risk of deep vein thrombosis. The contribution of senescence in the vasculature to the age-associated risk of venous thromboembolism is still a new field. We are beginning to better understand the role of cellular senescence linked to arterial disease occurrence; by contrast, we understand very little about the influence of senescence to venous thromboembolic diseases. Thus, we are trying to better understand the pathophysiological link between the occurrence of VTE with age and senescence.|

|J. Victor Garcia||Infectious Diseasesemail@example.com||In vivo analysis of HIV persistence: towards a CURE for AIDS||Since the beginning of the AIDS epidemic almost 40 million people have been infected. Many that receive appropriate medical care including antiretroviral therapy live highly productive lives. However, these patients live with the stigma of being HIV infected and the need to continue treatment for life. Our goal is to elucidate the molecular basis of HIV latency and persistence with the long-term goal of eradicating the virus from the host. For this we use highly innovative in vivo models that permit the in vivo analysis of HIV replication and presistence.

|james faber||Cell & Molecular Physiologyfirstname.lastname@example.org||Human Retinal Vascular Patterning and Palmar Collateral Blood flow as Non-Invasive Predictors of Pial Collateral Circulation||My laboratoryâ€™s interests concentrate on the collateral circulation (â€œendogenous bypass vesselsâ€) in brain, heart and peripheral limb. Compared to the general arterial-venous and lymphatic circulations, much less is known about collateral vascular biology. For example, until our work nothing was known about when or how these unique anastomosing vessels form or the molecular mechanisms involved. We have that discovered that these vessels form late in gestation after the general and lymphatic circulations have become established. Our studies have also found that the extent (ie, density, diameter, lengthâ€”thus conductance) of the native pre-existing collateral circulation in healthy individuals (inbred mouse strains) varies dramatically from naturally occurring genetic polymorphisms, and showed that these differences have a major impact on tissue injury and collateral flow recovery in mouse models of occlusive disease, including middle cerebral artery occlusion. We have also identified the first two genes (Vegfa and Clic4) whose expression significantly impacts formation of the native collateral circulation, and have used quantitative trait loci and SNP association mapping to identify additional candidate genes responsible for genetic variation in extent of the collateral circulation. Besides genetic factors, we are also studying the effect of environmental factors, disease risk factors, and gene-environment interactions for adverse effects on formation and maintenance of the collateral circulation in utero, perinatally,and during growth to adulthood and thereafter, as well as effects on extent of collateral remodeling in occlusive disease.
Available funds will be necessarily devoted to costs of retinography and ultrasonography.

|Janey Phelps||Anesthesiologyemail@example.com||Utilization of general anesthesia for MRI studies in pediatric patients||This is a retrospective study examining both the patient\'s age and type of MRI scan that children are being anesthetized for scan completion. This study is relevant because there is a growing body of literature that general anesthesia can have potential long term cognitive effects in children <3 years old. Pediatric patients often require general anesthesia in order to complete MRI scans. This study will utilize a database through the UNC pediatric pain sedation and consult service and EPIC following IRB approval to determine patient demographics, patient diagnosis, general anesthesia time, ordering service, and type of MRI scan performed. Children are receiving numerous studies that expose them to general anesthesia that may not alter their diagnosis or change their treatment plan. We anticipate follow up studies after this initial data gathering to further examine if a diagnosis was altered or a treatment plan was changed based on the MRI findings.|
|Janey McGee||Anesthesiologyfirstname.lastname@example.org||High Dose Dexmedetomidine in Pediatrics for Procedural Sedation||As a pediatric anesthesiolgist and the Medical Director of the Pediatric Sedation Service at UNC I have an interest in pediatric sedation and pain management. I have conducted a few clinical research studies in these areas. I am interested in working with Ali Russell to complete a chart review and analysis of the experience with high dose dexmedetomidine for pediatric procedural sedation at UNC and compare our results with those published previously.
Pediatric patients often require sedation in order to perform noninvasive procedures such as imaging studies. In January 2011, UNCâ€™s Pediatric Sedation Service adopted a noninvasive procedure sedation protocol designed by Dr. Keira P. Mason of Childrenâ€™s Hospital of Boston. The protocol uses high dose dexmedetomidine in children in order to achieve sedation for procedures like radiological imaging studies, specifically Magnetic Resonance Imaging (MRI). One of the key benefits of Masonâ€™s design was the fast recovery time which allowed patients to be discharged sooner and suffer lower risk of sedation-related morbidity. However, the recovery times that Mason has published are inconsistent with what has been observed at UNC. This study aims to compare measured dexmedetomidine recovery times achieved through the Pediatric Sedation Service at UNC with the recovery times previously published. The hypothesis of this study is that pediatric patients treated with high dose dexmedetomidine for noninvasive procedures have longer time to discharge than previously published.
|Jen Jen Yeh||Surgeryemail@example.com||Genomics and therapeutics in pancreatic cancer||Dr. Yeh is a physician-scientist with an active surgical oncology practice focused on endocrine and pancreatic cancers. Her research and surgical oncology practice has focused on identifying vulnerabilities in pancreatic cancer in order to develop better treatment for patients using a combination of translational approaches. Using her surgical expertise she initiated a large Patient-Derived Xenograft Program with a major emphasis on the establishment of both primary and metastatic pancreatic tumors in order to use this platform for therapeutic and biomarker evaluation. Recently her group identified new subtypes for pancreatic cancer that was published in Nature Genetics. Pancreatic cancer is a particularly difficult cancer to analyze because of its confounding and dense stroma and low tumor content. To solve that problem her group used a computational approach to separate the normal from the cancerous tissue and the stroma. These results help understand some of the controversy in the field regarding pancreatic stroma and will set the groundwork for future clinical trials, allow treatments to be assigned based on the subtypes, and guide the development of new therapies. The multidisciplinary nature of her work highlights her ability to meld disparate disciplines for pancreatic cancer research.|

|Jimena Giudice||Cell Biology & Physiologyfirstname.lastname@example.org||Alternative splicing in development and diseases||Alternative splicing is a posttranscriptional mechanism that explains how individual genes can produce more than one transcript due to the inclusion or exclusion of specific regions originating multiple protein isoforms with diverse features. More than 90% of human genes undergo alternative splicing. During development multiple transcriptional networks are coordinately regulated to drive organ maturation, tissue formation, and cell fate.
A wide variety of human diseases are caused by mutations within cis-acting sequences of pre-mRNAs that produce aberrant splicing and alter function of the mutated allele (Duchenne muscular dystrophy, Cystic fibrosis, among others). In addition, certain splice isoforms are depleted or induced in cancer, diabetes, or muscular dystrophies suggesting specific physiological roles. Defects in functions or expression of RNA-binding proteins and core spliceosome constituents induce splicing mis-regulation in multiple severe diseases.
Tissue specific alternative splicing is critical to maintain tissue identity. Brain, heart, and skeletal muscle are the tissues where the most tissue specific splicing takes place raising the questions of: how developmental stage- and tissue-specific splicing influences protein function and how this regulation occurs. To investigate this big-picture question, our research program has three angles:
- the molecular mechanisms that explain how alternative splicing regulates the expression of trafficking and membrane dynamics proteins in normal development and diseases.
- how alternative splicing impacts on the functions of membrane trafficking proteins in internal cell architecture and physiology.
- the roles of epigenetic dynamics on alternative splicing regulation in postnatal striated muscle development.

|Joan Taylor||Pathology & Laboratory Medicinefirstname.lastname@example.org||Development of Human Hypertension; Discovery of Novel Means to Mitigate Cardiac Necrosis||We have two projects to chose from
1) Translational: Although several large GWAS identified a novel locus in the ArhGAP42 gene that was associated with blood pressure (BP), no causal link has been established between these SNPs and the pathogenesis or outcomes of hypertension. Our group has shown that ArhGAP42 is specifically expressed in smooth muscle and negatively regulates BP in mice by inhibiting RhoA activity and that the minor allele at rs604723 was associated with increased ArhGAP42 expression in human arterial samples. Our genotype/phenotype analysis revealed that the minor BP allele increases ArhGAP42 expression and protects against the development of hypertension in Caucasians. Interestingly, the protective allele is under-represented in African Americans. This project we will use DNA samples from case-controlled studies to determine if allelic variations in ArhGAP42 affect genetic risk for hypertension in African Americans and will explore associations with clinical manifestations(i.e. hypertensive arterionephrosclerosis)in both races.
2) Basic Science: Hearts are vulnerable to a multitude of pathological insults including ischemia-induced necrosis. Previously, necrosis was viewed as a passive/irreversible cell death and was ignored as a target for clinical intervention. However, recent work indicates that necrosis is a reversible cell signaling process. We recently performed a novel genome wide siRNA screen to identify new modulators of calcium induced necrosis. This project would focus on determining which of these factors promote survival of cardiomyocytes in response to ischemia in the hopes of identifying new therapeutic targets to treat ischemic heart disease.

|John Vavalle||Cardiologyfirstname.lastname@example.org||TAVR - Transcatheter Aortic Valve Replacement: Improving patient selection and clinical outcomes||Over the last several years, there have been rapid advances in our ability to perform minimally invasive heart valve replacements and repairs using catheter-based devices. Transcatheter aortic valve replacement (TAVR) provides a life-saving procedure for those who are high risk for surgical valve replacement. There is a very large and growing unmet need for percutaneous valve replacement and repair due to the aging US population. Severe symptomatic aortic valve stenosis carries a very poor prognosis without valve replacement. However, many of the patients in need of valve replacement are at high risk for surgery. Therefore, transcatheter aortic valve replacement becomes the best therapy for them.
Since this technology is so new, there are many unanswered questions about the best use of this technology. Complications such as paravalvular leak, heart block, and vascular injury remain a big limitation to this therapy. Much research is needed to best identify which patients will benefit the most from this technology and to improve the application of these new devices. There are robust clinical databases that are stored at UNC and beyond that can be accessed to ask these important questions. Given that this field is so new, the opportunities for research are wide open and a motivated student would be able to lead a research project under the mentorship of the UNC Heart Valve Team.

|Jonathan Hansen||Gastroenterology & Hepatologyemail@example.com||How normal intestinal bacteria respond to inflammation and cause Crohn\'s disease and ulcerative colitis||Crohn\'s disease and ulcerative colitis, collectively known as inflammatory bowel diseases (IBD\'s)are chronic intestinal inflammatory disorders that cause substantial morbidity. Despite decades of intensive research, the pathogenesis of IBD\'s is not completely understood and medical cures remain elusive. The prevailing hypothesis is that IBD\'s are due in part to dysregulated immune responses to normal intestinal bacteria. While much is known about how bacteria affect the host immune system, relatively little is known about how inflammation in turn affects the bacteria. We hypothesize that inflammation induces changes in commensal gut bacteria that alter their virulence and colitogenic potential. We are currently testing this hypothesis using novel mouse models of IBD\'s and genetically-engineered commensal bacteria. Our ultimate goal is to identify microbial functions that can be targeted for therapeutic purposes in patients with IBD\'s.|

The recent revolution in genetic sequencing technology has led to an unprecedented opportunity to investigate the underlying etiology in families with genetic conditions, ranging from the discovery of novel disease susceptibility genes in large pedigrees, to the application of genome-scale sequencing in a clinical context.
I am a board certified medical geneticist in the UNC Adult and Cancer Genetics clinic. My clinical effort involves the evaluation of individuals and families with Mendelian disorders, including hereditary cancer syndromes, connective tissue disorders, and other rare genetic conditions. My ongoing research efforts extend directly from my clinical activities.
My laboratory is enrolling probands with a strong family history of cancer but negative results on clinically available genetic tests. We hypothesize that these families harbor rare deleterious mutations in potentially novel cancer susceptibility genes and we are utilizing high-throughput sequencing to identify candidate disease-causing mutations.
I am also co-PI of an NHGRI-funded U01 Clinical Sequencing Exploratory Research (CSER) project called â€œNCGENESâ€ that examines the utility of whole exome sequencing (WES) in a clinical context.

Using a variety of gene targeted animal models we have characterized a novel role for adrenomedullin and its receptors in the development and function of these cardiovascular organs. Our interests in cardiovascular biology are broad and highly integrative, since we have discovered that the functions of adrenomedullin signaling are largely influenced by other angiogenic and endocrine factors, hypoxia and innate immune responses. Therefore, our current studies are geared toward providing novel insights into the complex processes that govern the establishment of lymphatic and placental vascular beds and how perturbations in these specialized vessels can have deleterious consequences such as lymphatic disorders or poor pregnancy outcomes. We are currently focusing on the effects of perturbed lymphatic function on the absorption of lipids from the digestive tract.

|Kenneth Kim||Obstetrics & Gynecologyemail@example.com||The impact of BMI on treatment and outcomes in cervical cancer||In this country, the incidence of cervical cancer persists, but has been drastically reduced since the advent of routine screening with Pap smear testing. Research has demonstrated associations between obesity and various types of cancer, including virtually all types of gynecologic cancer, and furthermore can negatively impact the management of these cancers. With increasing levels and increasing incidence of obesity, and particularly with increasing obesity in cervical cancer patients, we seek to study the impact of varying levels of obesity on the treatment and the survival outcomes on cervical cancer patients. We postulate that obesity will have a negative impact on the primary treatment of cervical cancer, particularly early stage cervical cancer where the standard of care is typically radical surgery to remove the cancer. With increasing levels of BMI, these patients may not be surgical candidates to undergo surgical management and thus must be treated with radiation therapy compared to patients with lower BMI levels. Furthermore, treatment planning with radiation can be negatively affected by extreme obesity as well. We hypothesize that this will translate to worse outcomes for obese patients with cervical cancer.
To determine this, we will construct a retrospective database of cervical cancer patients, and divide these patients into 3 separate groups based on BMI: 40. Then we will analyze their treatment and their outcomes, and utilize comparative statistics to analyze differences. We will also evaluate for whether there are increased complications and comorbidities based on BMI levels.

Over the past 18 years, my clinical research program has focused on sport-related concussion. Our research team, which includes neurosurgeons, neurologists, neuropsychologists, neuroradiologists, epidemiologists, biomedical engineers, athletic trainers and team physicians, has investigated the effect of sport-related concussion on balance and neuropsychological function in high school and collegiate athletes, the biomechanics of sport concussion, and the long-term neurological effects of concussion in retired professional football players. More recently, we have expanded our research to the military, to compare neurocognitive and neuroimaging (DTI) results in soldiers pre and post blast-injury. Additionally, we have begun studying the effects of North Carolina\'s recently passed Gfeller-Waller Concussion Act on the way physicians manage concussion. As background, our research team typically mentors 8-9 graduate students, 4 undergraduates, and 2 residents/fellows in a given year. I have received 24 funded research grants, and published over 130 journal articles and 8 textbook chapters on sport concussion. I have presented over 250 national and international lectures on the topic of sport-related concussion. In 2010 I was named to the NCAAâ€™s Concussion Committee and the NFLâ€™s Head, Neck, and Spine Committee.

|Kristy Richards||Hematology & Oncologyemail@example.com||Genetic and Genomic Approaches to Understanding Lymphoma Biology and Improving Treatments||My research is focused on genetic/genomic approaches to understanding the biology and treatment of hematologic malignancies. We apply genetic approaches to understanding drug resistance to a variety of agents used to treat hematologic malignancies, as well as molecularly characterize pet dogs as a model organism to study non-Hodgkin lymphoma. One example of our work in human patients is with the FCGR3A gene, which has been shown in retrospective studies to predict responses to rituximab, a monoclonal antibody frequently used in the treatment of B-cell non-Hodgkin lymphoma. We are conducting retrospective and prospective clinical trials eventually seeking to translate these observations into clinically useful treatment algorithms. At the same time, while establishing this clinical pharmacogenetic proof-of-principle using the known FCGR3A polymorphism, we seek novel polymorphisms that likewise will improve and individualize future lymphoma therapies. To do this, my laboratory is utilizing an unbiased genetic approach, rather than the candidate gene approach that was used to identify FCGR3A and most other known clinically relevant polymorphisms. We are mapping polymorphisms that determine rituximab sensitivity, as well as a variety of other drugs used to treat hematologic malignancies, using an ex vivo genetic mapping strategy with the lymphoblastoid cell lines from both related (traditional linkage mapping) and unrelated (GWA studies) individuals. We have mapped candidate genes and are in the process of characterizing them further. The eventual goal of our work is to bring genetically tailored therapies to lymphoma patients.|

|Laurence Katz||Emergency Medicineemail@example.com||Infrared imaging to evaluate resuscitation during shock||Shock is insufficient tissue blood flow (perfusion) and oxygen delivery to body tissues, a leading cause of death from trauma. The decrease in perfusion and oxygen availability result in organ failure or patient death unless perfusion and oxygen deficits are recognized and treated. It is difficult to evaluate if adequate perfusion and oxygen have been restored during resuscitation from shock since there are no reliable methods to detect hypoperfusion or changes to perfusion during resuscitation. Assessments of peripheral circulation have been shown to be indicators of hypoperfusion and shock. However, most measures of peripheral circulation are subjective and difficult to monitor dynamically. Skin temperature decreases as peripheral circulation decreases, but it has not been measured during shock and resuscitation. As a result, we propose to longitudinally measure skin temperature with infrared thermography during shock and resuscitation. We hypothesize that infrared thermography, a non-invasive, non-radiation technology may provide a tool to detect shock and guide resuscitation.|

|Lola Reid||Cell Biology & Physiology||basic||no||Lola.M.Reid@gmail.com||Genetic signatures of stem/progenitor populations in the network for hepatic and pancreatic organogenesis||We have identified maturational lineages of cells emanating from primitive endodermal stem cell populations, biliary tree stem cells (BTSCs), which are found within Brunnerâ€™s Glands, in peribiliary glands (PBGs) throughout the biliary tree, and in the crypts of villi of the gall bladder. They give rise to hepatic stem cells (HpSCs) and hepatoblasts (HBs), located in or near the canals of Hering within liver acini, and to committed pancreatic progenitors in pancreatic duct glands (PDGs) found throughout the pancreas. These in turn give rise to the mature cells of the liver (hepatocytes, cholangiocytes), and pancreas (acinar cells, islets).
The maturational lineages progress along radial and longitudinal axes. The radial axis begins with primitive BTSCs in the centers of bile ducts and transitions to mature cells at the bile duct lumens. The longitudinal axis begins with high numbers of primitive BTSCs within Brunnerâ€™s Glands in the duodenum and in the PBGs in the hepato-pancreatic common duct next to the duodenum, and transitions to mature cells in the liver and along a separate branch to mature cells in the pancreas. The lineages constitute networks of niches that collectively participate in organogenesis for liver and pancreas throughout life. We have identified many of the major stages within the hepatic pathway (at least 10), and we are part way towards defining those for pancreatic fates (so far, at least 7).
We are defining transcriptomic signatures (global RNA-seq analyses) of each of these stages and have done a number, but not all, of the critical ones in the hepatic pathway and, so far, none in the pancreatic pathway. However, we intend to complete the process for all of the major stages and do the initial analyses over the coming year. Given that such transcriptomic signatures will comprise up to 30,000 genes as well as long, non-coding RNAs per maturational stage, it will take longer than the time of this funded proposal to fully understand the resulting data using bioinformatics. However, even the initial studies should enable us to know to what stage(s) the grafted stem cells have matured and for what functions they are capable. Also, from the gene expression landscape in each of the distinct stages, we will learn of signals that might be used to regulate the cells towards full maturity. In addition, in studies completed over the past year, critical changes were identified that can occur with malignant transformation, information important in the design of grafting strategies to avoid such changes.
The hepato/pancreatic organogenesis model systems being used consist of those in mice, humans and pigs. As background, we have characterized basic stem cell and maturational lineage biology in all of these species and established methods of isolation of the relevant cell sub-populations, serum-free, wholly defined organoid culture methods, and serum-free cryopreservation and thawing protocols for organoids and cells. In addition, we have defined the graft composition and the surgical procedures that optimize engraftment into target sites with minimization of complications such as adhesions. We hope to transition within a few months to functional studies to assess the extent to which transplanted stem cells have matured into relevant adult fates. The global transcriptomic studies to be done on freshly isolated cells will serve as the controls for the transcriptomic signatures to be analysed on transplanted cells.
We have organized to obtain â€œenblock tissuesâ€ from human neonatal donors and to consist of the liver, biliary tree (including the gall bladder), duodenum, hepato-pancreatic common duct and pancreas from each donor. By having all of the tissues from the same donor, we will be able to eliminate confounding inter-individual variations. The tissues from at least three human donors will be obtained and, in parallel, porcine tissues, and used by the Reid lab (Drs. Wencheng Zhang and Xianwen Yi, and others) to isolate purified cell populations of the major stages of the hepato/pancreatic network. In addition, they will isolate mesenchymal (CD146+), endothelial (CD31+) and hemopoietic (CD45+) cell subpopulations. These samples will be prepared for sequencing by the Sethupathy lab (Dr. Lisa Kurtz and an MD/PhD Student, Mr. Timothy Dinh) and provided to core services at UNC or at commercial labs to generate the raw data for conventional RNA sequencing, small RNA sequencing, and methyl sequencing. The raw data will be analysed by Dr. Sethupathy and his associates with the help of a bioinformatics specialist, Dr. Wendy Pitman, and by Mr. Dinh. The findings from these studies will provide the control data that will guide us in analysing the fate of transplanted cells.
|Luis Diaz||Otheremail@example.com||Autoimmune Diseases of the Skin||The aims of my two RO1s are focused on the etiological and pathogenetic mechanisms of three human autoimmune diseases of the skin: bullous pemphigoid (BP), pemphigus vulgaris (PV) and pemphigus foliaceus (PF). Our laboratory pioneered the development of animal models for the three diseases by passive transfer of human anti-epidermal autoantibodies from patients. We have characterized the relevant epidermal antigens. Currently we are conducting epitope mapping studies to disclose the regions of the epidermal antigens responsible for binding pathogenic autoantibodies. In addition, we are conducting research in an endemic form of PF seen in Brazil, where the epidemiology suggests that this disease is triggered by an environmental factor(s). We are following an Amerindian population with a high prevalence of the disease and determined the preclinical stage of the disease by seroepidemiological studies. These studies are shedding light on the progress of autoimmune diseases from the normal state (preclinical) to the disease state using highly sensitive autoantibody markers. A combined use of these serological markers, the epidemiological data generated in the abovementioned Amerindian Reservation, and the study of environmental factors provide us with the opportunity to identify etiological agents of this human autoimmune disease.|

Longterm sequelae of malnutrition include increased risk of infection-related mortality, poor neurocognitive development, and impaired vaccine responses. Recurrent intestinal pathogens, including parasites, are syndemic with childhood malnutrition in low-resource settings. How these environmental microbial exposures promote gut dysfunction or modulate host immunity are poorly understood, and therefore current treatments for malnutrition are of limited benefit. Using novel murine infections models of human enteric parasites, we aim to understand the pathogenesis of parasite-induced chronic intestinal dysfunction and the impact of intestinal parasitic infections on host immunity, co-infections, and adaptations to nutrient deficiency. Our studies dissect environmental, resident microbial, dietary, and host influences on these outcomes in order to improve restorative interventions in malnourished children.|

Studies with Latinas have underscored the importance of the family as a cultural value affecting recognition of the eating disorders as well as the centrality of the role of the family and its relationship to food and body image in Latino culture. My current work builds on my experience working with adults with bulimia nervosa in Puerto Rico which underscored the importance of incorporating the family early in treatment as a necessary cultural adaptation for Latinas. A second line of my research is to develop culturally sensitive psychoeducational materials that raise awareness and educate the Latino population about eating disorders. Considering that Latinos regularly delay treatment until symptoms are severe, tend to underutilize mental health services, and often terminate treatment prematurely, awareness and education could lead to early detection and be particularly helpful in reducing mental health care disparities. The development of fotonovela scripts (graphic novels) about eating disorders tailored for adolescent and adult Latinos will be used as a culturally sensitive way to raise awareness about these disorders in the Latino population.|

Early diagnosis and improved outcome rely in large part on identifying genomic profiles predictive of malignant progression, level of tumor burden, and druggable biochemical pathways. Pertinent laboratory technology is now available to facilitate relevant analytic and clinical validation studies towards implemeting genomic tests to improve patient diagnosis and management. These tools involve multi-analyte tests of DNA, RNA and microRNA in small biopsies to identify the genetic profiles that characterize the four major classes of gastric cancer and their precursor lesions. Our assay development program builds on prior discovery work to macrodissect small lesions from formalin-fixed, paraffin embedded biopsies and to define the histo-molecular correlates underlying cancer progression. We are also examining blood plasma for circulating tumor markers that likewise inform early diagnosis, monitoring tumor burden in response to therapy, and finding actionable gene variants to improve drug selection. In addition to analyzing human genome targets, we assay for virulence factors in two carcinogenic pathogens, helicobacter pylori and Epstein-Barr virus.

|Maureen Su||Pediatricsemail@example.com||Genetics of Autoimmunity||Autoimmune disease affects more than 8 million Americans, including 1 in 100 children. Despite its prevalence, the complex, polygenic inheritance of most autoimmune disorders has been an obstacle in understanding the pathogenesis of these diseases. Autoimmune Polyendocrinopathy Syndrome (APS) Type I is unusual among autoimmune diseases in that it is due to a defect in a single gene, Autoimmune Regulator (Aire). Aire plays an important role in preventing autoimmunity by upregulating the transcription of a variety of peripheral self-antigens in medullary thymic epithelial cells (mTECs) of the thymus, and the expression of these peripheral self-antigens drives the deletion of self-reactive T cells in the thymus.
We have utilized mice with defects in the Aire gene to understand how Aire is important in preventing autoimmunity. We are currently focused on studying a mouse model with a dominant point mutation (G228W) in Aire which results in spontaneous autoimmunity in a number of organs, including the thyroid gland, peripheral nerves, and pancreatic islets. The G228W mouse model provides a unique opportunity to study the role of central tolerance in preventing autoimmunity toward these organs. We are also utilizing the G228W mouse model to inform us on how Aire functions. The ultimate goal is to translate our findings to human autoimmunity both in terms of understanding the mechanisms underlying human disease as well as in developing therapeutics for treating autoimmunity.

These anti-VEGF drugs will have been injected into their eye as treatment for the retinal edema which occurs during the healing phase following the onset of their retinal vein occlusion.
Anti-VEGF drugs work to decrease retinal edema. Oxygenation of the retina does the same thing. However, the concurrent effects of intravitreal anti-VEGF drugs on the oxygenation of the retina via the retinal circulation is currently unknown.
Using a non-invasive technique, called retinal oximetry, we will take (risk free)fundus photographs of the retina in these patients throughout the course of their treatment with anti-VEGF injections, and record changes in retinal oxygenation during this period.
We will determine the effect, either positive or negative, of injected anti-VEGF drugs on the normal oxygen supply to the retina during a course of treatment of a retinal vein occlusion using the current standard of care anti-VEGF injections.

Training of ophthalmologists to perform the screening and treatment of retinopathy of prematurity (ROP) is not keeping up with these changes. Proper ROP training is expensive and time consuming, however. In the USA, training typically takes a year throughout a retina or pediatric ophthalmology fellowship. Telemedicine in ROP has been previously validated using RetCam photographs. In this study, we will pilot the use of telemedicine as a teaching tool in ROP. The study involves designing a schedule for ROP image transfer, establishing the parameters for validating the teaching method, coordinating the transfer and storage of RetCam images, and creating a feasible infrastructure for providing feedback and teaching. The study may involve a 2 week trip to Lanzhou, China to help train nurses and ophthalmologists in the proper use of the RetCam device, coordinate proper ROP screening and treatment infrastructure, and establish the Chinese side of telemedicine transfer. During that trip, other ophthalmologic clinical and surgical teaching will take place, whereby the student can observe and participate. Skills in Mandarin would be particularly useful.

|Monte Willis||Pathology & Laboratory Medicineemail@example.com||Proteotoxicity in heart failure and the development of new therapeutic interventions||The overarching theme of our work is to investigate protein quality control and proteotoxicity in genetic and non-genetic forms of heart failure. We dissect out the molecular regulation of signaling networks that mediate disease in genetic and pathological heart failure models. In parallel, we develop targeted therapies that reduce or block proteotoxicity in the hopes of developing new clinical treatments for heart failure.
Project 1: The broad, long-term goal of this project is to delineate the mechanisms that Muscle Ring Finger (MuRF) ubiquitin ligases regulate PPARÎ±, PPARÎ²/Î´, and PPARÎ³1 activities, mitochondrial dynamics, and autophagy in the context of heart failure. Our central hypothesis is that the MuRF1 ubiquitin ligase inhibits PPARÎ±, reduces mitochondrial ROS production, and enhances autophagy to contextually protect cardiomyocytes in heart failure.
Project 2: As part of the Leducq Foundation TransAtlantic Network of Excellence, this project investigates proteotoxicity as an unappreciated mechanism of heart disease and its potential for novel therapeutics. This project investigates the two major pathways of protein breakdown: 1) the autophagy-lysosomal pathway; and the 2) ubiquitin-proteasome system. Defects in either one can lead to the toxic buildup of misfolded proteins and, ultimately, heart failure. Our projects involve identifying MuRF1â€™s regulation of autophagy and more recently identifying the causes of cardiac dysfunction resulting from human mutations in Bag3. Using a Bag3 P209L cardiac-specific mouse model, weâ€™re investigating how pre-amyloid oligomers alter redox and MAPK signaling pathways to induce cardiac dysfunction.

|Natasha Snider||Cell Biology & Physiologyemail@example.com||Liver Disease Mechanisms and Drug Targets||Dr. Sniderâ€™s lab studies the molecular basis of liver diseases and disorders linked to intermediate filament gene mutations. Her team uses biochemical, cell-based and in vivo approaches to identify potential disease targets and to understand their function and regulation. The major goal of Dr. Sniderâ€™s work is to promote the discovery of pharmacological agents that can slow or halt the progression of these diseases.
Liver disease development and progression are dictated by the individual and combined contributions of different genetic and environmental factors. Our previous work in mouse models linked liver injury susceptibility to the function of energy metabolism regulators, including the glycolytic enzyme GAPDH and the purine metabolizing enzymes nucleoside diphosphate kinase (NDPK) and ecto-5\'-nucleotidase CD73. Current efforts in the lab are aimed at understanding the regulation and cell-specific functions of CD73 in various stages of liver disease, including fibrosis, cirrhosis and hepatocellular carcinoma.
Intermediate filaments (IFs) are cytoskeletal structures that perform important mechanical and signaling functions. IF gene mutations are linked to a vast number of human pathologies, including skin fragility disorders, neuropathies, myopathies, liver diseases, metabolic dysfunctions, and premature aging syndromes. Effective treatments for diseases caused by IF gene mutations are lacking. Our long-term goal is to define the proteostasis network of IF proteins and to identify key features that are compromised by disease-causing or disease-promoting mutations. We are currently focused on various post-translational modifications (PTMs) and their cross-talk mechanisms.
|Nicholas Shaheen||Gastroenterology & Hepatologyfirstname.lastname@example.org||Prevention of Esophageal Cancer||Our group has been at the forefront in research in cancerous and pre-cancerous conditions of the esophagus. Esophageal cancer is a highly lethal cancer, with less than 15% five-year survival, and its incidence is rapidly increasing. Patients who develop esophageal cancer often have a precursor condition, Barrett\\'s esophagus, also known as BE. Many people have BE - as many as 2-3 million Americans. If BE goes bad, it does so through a series of steps, called dysplasia. Our goal has been to identify those whose BE will progress to cancer, and to make an intervention to stop death from cancer.
Our center is one of several in the U.S. that have been dedicated to developing technologies to reverse the malignant degeneration in BE, while sparing the esophagus. We recently led a national consortium of centers in a sham-controlled, randomized trial of radiofrequency ablation, an endoscopic technology which destroys BE. This study, published in New England Journal of Medicine in May, 2009, demonstrated that subjects treated with the therapy had greater than 75% reversion to normal squamous epithelium, and a decrease in their risk of cancer of greater than 80%. We also are the lead U.S. center on a study of endoscopic cryotherapy using liquid nitrogen to ablate Barrett\\'s esophagus.
We are currently working on biomarkers, or early indicators, of progression to cancer in these patients.
|Nigel Mackman||Hematology & Oncologyemail@example.com||The role of tissue factor, coagulation, proteases, PARs and microparticles/microvesicles in hemostasis, thrombosis, and inflammation.||The focus of the Mackman laboratory is a protein called tissue factor (TF). This transmembrane receptor is the primary cellular activator of the coagulation protease cascades. TF is expressed constitutively on perivascular cells and initiates clot formation. After vascular injury, factor VIIa (FVIIa) binds TF and the complex initiates the clotting cascade by cleavage of FX to FXa and FIX to FIXa. Subsequent amplification of the clotting cascade by the intrinsic pathway produces large amounts of thrombin that cleave fibrinogen, activate FXIII and activate platelets. Tissue factor pathway inhibitor (TFPI) and activated protein C (APC) act to attenuate the clotting response. Coagulation and inflammation are linked through activation of protease-activated receptors (PARs). Activation of the clotting cascade leads to the generation of proteases that can cleave and activate PARs. PAR-1 is activated by thrombin and FXa, PAR-3 and PAR-4 are activated by thrombin, and PAR-2 is activated by FVIIa and FXa. This allows cross-talk between coagulation and inflammation.|

Our approach consists of a series of experiments with mice carrying modifications in various genes specifying components important for maintenance of vascular health. Recent projects also include exploration of bone marrow derived mesenchymal stem cells as tools for studying pathogenesis of complex diseases and for cell-based therapies.
The short-tem project for a medical student will be to study the transdifferentiation processes of mesenchymal stem cells derived from adult tissues to cardiomyocytes in a culture system. The basic knowledge of similarities and differences between normal heart muscle cells and those grown in culture would facilitate the development of safe and effective procedures.
|Odette Houghton||Ophthalmologyemail@example.com||Cystoid Macular Edema and Retinal Imaging||Several conditions are associated with cystoid macular edema (CME) including diabetic retinopathy, age-related macular degeneration, retinal vein occlusions, uveitis, cataract surgery, vitreous traction, retinal dystrophies and drug reactions. Macular cysts are a major cause of central vision loss in these diseases. I am currently investigating the clinicopathologic correlation of the appearance of CME in biomicroscopy, spectral domain ocular coherence tomography (OCT), fluorescein angiography and a novel imaging technique using a scanning laser ophthalmoscope in retro-mode. I am also validating a unique automated method of segmenting cystoid fluid volume for use in clinical investigations. Qualitative analysis of macular cysts may be used to objectively evaluate treatment and could provide a sensitive outcome measure in interventional studies.
In addition to correlating the morphology of cysts using various imaging modalities, I am planning 1) an investigation of the morphologic features of macular cysts on OCT in response to the treatment; 2) a cross sectional study on the morphology of macular edema on OCT in diabetic patients with concomitant hypertension and/or end-stage renal disease and; 3) a retrospective study investigating the progression of preexisting ocular conditions in patients requiring multiple intravitreal injections of anti-VEGF agents. The latter two studies will require the extraction of data and interpretation of images using existing department of ophthalmology patient records.
I am also working with other investigators in the department of ophthalmology to determine the effect of vitreoretinal surgery on oxygen saturation in retinal vessels using a retinal oximeter.

|Pauline Kay Lund||Cell & Molecular Physiologyemail@example.com||Obesity, intestinal stem cells and colorectal cancer||Current views suggest that inappropriate survival and expansion of genetically damages intestinal epithelial stem cells (IESC) is critical to tumor initiation in the colon. Obesity, an epidemic in the western world, promotes colorectal cancer (CRC) but mechanisms are not defined. Furthermore, small but growing evidence suggests that obese or type 2 diabetic patients show reduced responsiveness to radiation therapy for CRC and potentially worsened adverse effects of radiotherapy on gastrointestinal function. This summer project will provide an opportunity to participate in a project using intestinal stem cell reporter mice, expressing green fluorescent protein (GFP) specifically in stem cells to test the hypothesis that:
a) obesity expands the number of colonic stem cells and b) favors enhanced survival of genetically damaged colon stem cells after radiation therapy. Opportunities will be available to gain experience in one or more of the following methods or experimental approaches: a) mouse models of gastrointestinal disease, b) genetically manipulated mice and stem cell reporter mice, c) histopathology of the gastrointestinal tract (normal, after radiation or tumors), d) intestinal stem cell culture, e) immunofluorescence, f) assays of apoptosis and proliferation by histology or flow cytometry and g) real time PCR to follow-up on transcriptomic analyses of stem cells. Level of prior experience will determine which specific projects and methods will be feasible in a summer project. Up to two students will be considered.
|Philip Sloane||Family Medicinefirstname.lastname@example.org||Research foot care issues in older persons and develop a training video||Two medical student positions are available to participate in development, creation, and evaluation of an educational video on foot problems in older persons. Foot care is important but rarely gets much attention in medical education. Nearly a quarter of seniors report restricting activities because of foot pain; many turn to medical professionals for foot care because of impaired vision, arthritis, diabetes, or other problems; arterial and venous problems in the lower extremity are very common; and infected foot ulcers are the leading cause of leg amputation.
The project will be under the direction of Philip Sloane, MD, MPH. Dr. Sloane is the Elizabeth and Oscar Goodwin Distinguished Professor of Family Medicine and a specialist in geriatric medicine. Also working with the students will be two nurses who specialize in foot care and a video education company.
During the first 4 weeks of this summer experience, a student will review the literature on foot problems in older persons; work 2 days a week with clinicians providing foot care; develop (with faculty assistance) a curriculum and plan for a training video; assemble photographs of foot problems and pathology; and begin drafting a video script on foot problems and care for nurses and other medical professionals-in-training. During week 5 the script will be finalized and plans for a formal evaluation developed. During weeks 6-8 the student will work with a production company to create a 50-minute training video, finalize the evaluation questionnaire, and work with faculty mentors to set up the project evaluation. During weeks 9 and 10 the student will present the video to 30 practicing nurses, nurse practitioners, and geriatricians for a formal evaluation, and will write a report on development and evaluation of the training video.
This combination of activities will assure that a student participating in this summer project will finish not only with skill development in educational program development and evaluation, but also in the clinical evaluation and care of foot problems in older adults. A poster and/or presentation will result and for the very motivated student the opportunity to co-author a manuscript.

We have focused on these techniques because certain patients may not be able or willing to tolerate surgical intervention. For example, solid organ transplant patients can see their risk of non-melanoma skin cancer (NMSC) increase by as much as 200-fold. It is often necessary to treat numerous concerning lesions at a time in order to contain risk of spreading. One such technique we have focused on involves using the chemotherapeutic agent, 5-fluorouracil (5FU) which can be injected directly into cutaneous squamous cell carcinoma. We have used this technique successfully to treat hundreds of skin cancers and we are looking to analyze the data in order to publish it within the next year. I hope that my background in basic science research as well as my clinical niche will allow me to thrive in my new role as director of cutaneous oncology here at UNC Dermatology.

|R. Jude Samulski||Pharmacologyemail@example.com||Gene Therapy||Dr. Samulski\'s research focuses on the study of the dependent parvovirus adeno-associated virus. AAV is the only known DNA animal virus which requires co-infection by a second unrelated virus in order to undergo productive infection. The DNA tumor viruses, adenovirus and herpes simplex virus provide the necessary helper functions for AAV. AAV not only utilizes gene products from these tumor viruses, but it interferes with their growth and with oncogenicity of cells transformed by these viruses. In the absence of a helper virus, AAV is able to integrate into host cell DNA and maintain a latent infection. Superinfection of these cells with a helper virus results in the rescue and replication of the AAV genome. The ability of AAV to integrate and maintain itself in host cells and subsequent rescue and replication of its viral sequences is of considerable interest. In some respects, this behavior is similar to phenomena observed with bacterial transposons, yeast movable genetic elements, Drosophila copia sequences, P elements, and the RNA tumor viruses. For this reason AAV has recently been described as a type of replicating transposon. Dr. Samulski has cloned the AAV genome into the bacterial plasmid pBR322 and demonstrated that this recombinant clone is infectious when introduced into human cells co-infected with a helper virus. This recombinant clone has provided a manipulatable system for the analysis of mechanism(s) involved in excision and integration of the adeno-associated virus genome. Based on these observations, he has been able to test AAV as a alternative viral vector for gene delivery. The ability to generate non-pathogenic viral vectors for current basic research have the long term potential of serving as reagents for use in clinical settings. He has established successful and long term gene expression over a year, which directly addresses the issue of molecular therapy required for genetic disorders. One of Dr. Samulski\'s current goals of research is to continue to derive delivery systems for use in gene therapy.|
|Ravi Jhaveri||Pediatricsfirstname.lastname@example.org||Influenza C Epidemiology-Insights into Flu Pathogenesis||Influenza viruses are a major cause of human infection and mortality. While Influenza A and B are the primarily associated with this burden, Flu C is increasingly recognized as a cause of human infections with a burden that has a seasonally distinct pattern when compared to Flu A and B. Each year, we have patients that are admitted to UNC with severe respiratory infections that go undiagnosed despite our best efforts. If we could better understand which patients get infected with Flu C and how it is transmitted, we could begin to prevent and treat these infections.
Our intial studies will encompass an anaylsis of human samples sent to the Molecular Microbiology lab at UNC that were previously tested using the Respiratory Virus Panel. We will test all samples as Flu C can cause infection alone but can also be observed co-infecting with other viruses. These samples will be batch tested by real-time PCR using Flu C-specific primers reported in the literature and validated in our hands using cloned plasmids. We will examine the patient characteristics of samples that test positive: age, geography, symptoms, co-morbid conditions, month/season. These results will define the burden of Flu C at UNC and provide us with real-world diagnostic experience using clinical samples.
The student will learn to isolate RNA from clinical samples, conduct the real-time PCR testing and will collect the clinical data. The student will meet regularly with the study team to discuss subsequent studies.

|Renae Stafford||Surgeryfirstname.lastname@example.org||Medical Profesionalism and Social media use: Are we missing an opportunity for education||The concept of medical professionalism is engrained in both medical student and graduate medical education. Beginning with the ABIM professionalism charter and closely followed by the addition of the competency of professionalism to the evaluation of graduate medical trainees by the ACGME, it has become a topic for much debate. It is often difficult to define and hard to measure. Students often enter medical school with out any prior knowledge of what will be expected of them and how they will be evaluated. As students enter the clinical world, what they have been taught in lectures or group discussions about professionalism may be seen to be at odds with what happens on the clinical wards. This dichotomy may be further widened in residency. The advent of the internet, blogs, media sharing sites such as You Tube and social networking sites such as Facebook, Twitter and MySpace has changed how students and residents interact with educators, their colleagues, the outside world and with patients. This creates challenges to professionalism and opportunities for education and engagement of trainees in discussions about this topic.
1) Perform a needs assessment of medical students, residents and faculty with respect to knowledge and attitudes surrounding medical professionalism
2) Examine studentsâ€™, residentsâ€™ and faculty social media use and attitudes toward social networking sites
3) Examine studentsâ€™, residentsâ€™ and faculty attitudes regarding appropriateness of on-line content with respect to medical professionalism
4) Develop an interactive curriculum on medical professionalism based on aims one to three above.

This is due in large part to the large amount of wasted or inefficient health care delivery in the United States that totals nearly $800 billion of the 2.7 trillion or ~40% of total healthcare expenses in our nation. This is felt to be potentially remediable by better educational and systems approaches to training and healthcare delivery.
Since 2013 we have been conducting a variety of educational interventions and clinical studies aimed at educating students, residents and faculty how to incorporate high value care practices into educational environments. Several projects around the overuse of telemetry, laboratory testing, and other technologies are ongoing. Educationally we have introduced HVC as an area of concentration in the TEC curriculum and other department specific resident education and faculty development.
Research as to the effects of these interventions both educational and clinical are ongoing but with room for expansion and new project development.

To improve the lives of patients with ANCA disease, we aim to elucidate the underlying immunologic and pathogenic mechansisms and translate this knowledge into improved patient care. We are currently investigating epigenetic regulation of neutrophil genes and genes that modify the phenotype of ANCA disease. We are exploring the biology of relapse and remission in a unique cohort of patients from the perspective of epigenetic regulation of autoantigen genes, B cell autoreactivity and T cell dysregulation. Using animal models of ANCA disease, we are studying involvement of the alternative complement pathway and Fcy receptors in pathogenesis, induction of disease by different antigens, and the genetic basis for variations in disease severity. Providing translation of our more basic research into clinical invesigations to improve ANCA disease outcomes, we will use our discoveries about pathogenic roles for epigenetic regulation and complement activation by treating patients with retinoic acid to alter myeloid gene expression and with anti-C5 antibodies to block complement activation. As an extension of the discovery of anti-plasminogen antibodies, we will determine if venous thrombosis in ANCA disease patients is attributable to these antibodies. Through the Glomerular Disease Collaborative Network, we have followed patients with ANCA disease for almost a quarter century, obtaining crucial clinical and pathological information and biological specimens for our research studies.

We particularly want to understand the controls on triacylglycerol synthesis, fatty acid oxidation, and acyl-CoA partitioning. These processes are impaired in conditions such as diabetes and obesity. Using recombinant forms of enzymes, knockout mice (mice bred with inactivation of specific genes), and cell culture models, members of our lab are identifying the control mechanisms that explain how acyl-CoAs, a group of fatty acid metabolites, are directed into the mitochondria for energy production or stored in lipid droplets as complex lipids.
Successful adaptation to a prolonged fast requires the liver to increase its production of glucose and its oxidation of fatty acids. Our studies of a new knockout mice provide strong evidence that the response to fasting requires a specific lipid; without the ability to synthesize this lipid, mice become hypoglycemic and their body temperature drops. We are now investigating the mechanism that underlies this phenotype.

1. Researching the literature on clinical efficiency in primary care, including patient flow in different clinical models;
2. Reviewing and analyzing data from the FMC clinical flow efficiency study;
3. Continuing to improve personal clinical efficiency skills in day to day clinical practice
4. Testing specific improvements suggested from literature search in both personal and team PDSA mini-projects
5. Producing a scholarly work (short paper or poster) demonstrating efficiency/flow lessons learned, and
produce to the FMC R&R committee for further augmentation of practice redesign process
The summer research project would be to develop, implement, and evaluate a spread strategy so that the improvements in clinical efficiency learned by Matt become available to other FMC faculty and residents who see patients in the FMC. Resources on spread strategies from the Institute for Healthcare Improvement will be utilized to structure the work. The hope would be to submit this work as a poster for presentation at a national meeting.
|Sam Lai||Microbiology & Immunologyemail@example.com||Immune protection based on interactions between IgG-Fc and mucins||Most infections transmit at mucosal surfaces, and our immune system secretes more antibodies into mucus than either the blood or the lymph. My lab uses various tools from biophysics and molecular biology to elucidate immune defense mechanisms at the mucosa. Specifically, we are discovered a novel mechanism of antibody protection at mucosal surfaces: trapping individual pathogens in mucus. Ongoing studies include quantifying the potency of this protective mechanism, the biochemistry governing antibody-mucin interactions, quantifying protection against both viral and bacterial pathogens in human secretions and different animal models across various mucosal secretions, and screening antibodies that may provide more effective protection. We welcome students with a keen interest in methods that improve protection against infectious diseases at mucosal surfaces for a short, 3-month research experience in our lab. The students will gain exposure to techniques in biophysics (high resolution fluorescence microscopy), Luminex multiplex ELISA, molecular biology, viral/bacterial cell cultures, animal studies, and studies with human specimens. Examples of our work in this area can be found at http://www.nature.com/mi/journal/v7/n5/full/mi2013120a.html and http://mbio.asm.org/content/6/5/e01084-15.

|Samantha Meltzer-Brody||Psychiatryfirstname.lastname@example.org||Epidemiological and Biological Predictors of Postpartum Depression||My research is focused on understanding the epidemiological and biological risk factors and underlying mechanisms of postpartum mood disorders (PMD). PMDs are the most common complication of childbirth and cause significant morbidity and mortality. Postpartum depression (PPD) has a prevalence of 10-15% and is the most frequent type of PMD. Postpartum psychosis (PP) is a rare but severe form of PMD that can result in tragic consequences including suicide and infanticide. The relationship between PPD and PP is uncertain, as is their relationship to major depressive disorder (MDD) and bipolar disorder (BIP). We currently have a poor understanding of who will develop PPD or PP, and whether and how the two disorders are related. Research focused on this line of inquiry could provide new knowledge crucial to understanding the risk factors and course of PMD that could eventually also prove to be key to understanding the etiology of mood disorders outside the perinatal period. This new knowledge will be significant because it will define the epidemiological and mechanistic predictors and course of PMD, thereby identifying a potentially modifiable risk factor for PPD and PP. Ultimately, this work will support strategies to identify women at risk and implement interventions to prevent PPD and PP and their adverse sequelae for mother and child.|

|Sandra Kim||Pediatricsfirstname.lastname@example.org||Commensal bacteria and associated virulence genes in children and adolescents with IBD||Our laboratory group is interested in the relationship between E. coli and E. faecalis, two commensal organisms associated with IBD in both humans and animal models of colitis, and associated virulence factors that mediate bacterial mucosal adherence, invasion, and intracellular survival. We hypothesize that both bacterial prevalence and virulence gene expression are increased in children with Crohn`s disease with genetic polymorphisms that mediate bacterial killing versus children with Crohn`s disease without these genetic polymorphisms or ulcerative colitis and healthy individuals. Ultimately, the induction of Crohn`s disease requires both host genetic susceptibility and expression of specific bacterial virulence genes. We will address these hypotheses by
(1) characterizing the frequency of mucosally - adherent bacteria and associated relevant virulence genes from intestinal mucosa of children with IBD and within different regions of the intestinal tract of these children and by
(2) determining whether polymorphisms of host genes that regulate bacterial processing and killing are associated with mucosal colonization with bacteria.
Our studies will delineate host genetic interactions with functionally altered E. coli and their associated virulence genes. Therefore, this information moves us closer to our clinical goal of better individualizing therapy; understanding the relationship between patient genotype and microbial profile will help us individualize therapy and avoiding complications both from the natural course of disease as well as medication toxicities.
Ultimately, these studies will help us develop a better understanding of the relationship between commensal organisms such as E. coli and E. faecalis, the genetically susceptible individual`s ability to process and kill these organisms, and metabolic pathways involved in disease pathogenesis.
Students who work with our group will have the opportunity to be involved in different aspects of translational research patient recruitment and data entry/analyses as well as the acquisition of skills in molecular microbiological techniques. There is ample opportunity to plan associated projects depending on individual interests and experience.

We are particularly interested in the role that microRNA play in this process, and how these microRNA molecules interact with other pain mediators to cause pain pathogenesis. The lab uses a combination of experimental and analytical techniques including next generation sequencing, reporter assays, bioinformatics, and statistical analyses.

|Saskia Neher||Biochemistry & Biophysiologyfirstname.lastname@example.org||Regulation of Lipoprotein Lipase Activity||My lab studies multiple aspects of lipase regulation. Mammalian lipoprotein lipase (LPL) plays a critical and complex role in lipid metabolism. In humans, deficient levels of LPL can cause hypertriglyceridemia and associated disorders, such as diabetes and atherosclerosis. LPL cannot efficiently exit the ER and achieve appropriate levels without a transmembrane protein whose identity was only recently discovered, lipase maturation factor (LMF1). In cells lacking LMF1, inactive LPL is retained in the ER as large eaggregates that are subject to degradation. We use biochemistry and cell biology to study how LMF1 promotes LPL exit from the ER. Once secreted into the blood, LPL activity is also regulated. LPL activity is inhibited by a protein known as ANGPTL4, which is induced in adipose tissue in response to fasting. We study the mechanism of ANGPTL4 inhibition of LPL.|

|Scott Magness||Gastroenterology & Hepatologyfirstname.lastname@example.org||Intestinal Stem Cells||The primary focus of my research is to understand the genetic mechanisms underlying stem cell maintenance and differentiation with the goal of translating this information into therapeutic strategies. We have identified that distinct levels of the transcription factor, Sox9, differentially mark stem cells and progenitor cells in the small intestine epithelium. Using a novel Sox9EGFP mouse model, cell surface markers, and FACSorting we are able to specifically enrich for single multipotent intestinal epithelial stem cells that are able to generate â€˜mini-gutsâ€™ in a culture system. Our studies are now focused on manipulating, in vitro, the genetics of stem cell behavior through viral gene therapeutics and pharmacologic agents. Additionally, we are developing stem cell transplantation and tissue engineering strategies as therapies for inborn genetic disorders as well as damage and disease of the intestine. A new area of research focus is on cancer stem cells. Using novel animal models and tissue microarrays from human colon cancers, we are investigating the role of Sox9 in colorectal cancer and assessing Sox9 expression patterns as a predictor of outcomes.|

To circumvent these limitations, we are utilizing mouse models of CRC in the Gnotobiotic Facility to test the following hypothesis: dietary fiber has a chemoprotective effect because it is fermented in the colon by anaerobic bacteria into a short-chain fatty acid called butyrate. Butyrate is the primary energy source of the colonic epithelium and also functions as a histone deacetylase inhibitor to regulate gene expression. Butyrate is known to confer chemopreventive properties on CRC cell lines based on decreased cell proliferation and increased differentiation or apoptosis. To test our hypothesis, low- and high-fiber diets (FOS/inulin or wheat bran) are being provided to C57BL/6 or BALB/c mice that have been treated with AOM or AOM/DSS to induce CRC in the absence or presence of inflammation. Some mice will be maintained in a germfree (GF) state, while others will be colonized with several ASF-strain bacteria that occupy specific niches of the GI tract and restore normalcy. More importantly, other mice will be colonized with a wild-type butyrate-producing strain (B. fibrisolvens) or a mutant that produces 5-fold less butyrate, both alone and in combination with the ASF. Scoring tumor number/grade of mice from the different experimental conditions will allow us to determine unequivocally whether fiber/microbes/butyrate influence tumor initiation or progression. Gene expression profiling, MeDIP-seq, ChIP-seq, and other molecular studies will investigate the pathway(s) and molecular mechanism.|

|Sean McLean||Surgeryfirstname.lastname@example.org||Basic Mechanisms of pulmonary hypertension in Congenital Diaphragmatic Hernia.||Pulmonary hypertension in patients with congenital diaphragmatic hernia is highly lethal. Presently no definitive treatment exists for pulmonary hypertension in CDH and other forms because the pathogenic mechanisms are complex and not understood. Pulmonary vascular remodeling is the central cause of pulmonary hypertension, and smooth muscle cells drive this process. Our laboratory investigates smooth muscle cell related mechanisms in the development of pulmonary hypertension. Specifically we focus upon the protein Slit-3 as a mediator of smooth muscle cell differentiation and migration in the development of the pulmonary circulation. We believe alterations in Slit-3 signaling contribute to alterations in smooth muscle cell function and phenotype that lead to the development of pulmonary hypertension. In our laboratory, we work with a mouse model for congenital diaphragmatic hernia, Slit-3 null mouse, to investigate the mechanisms related to pulmonary vascular remodeling in the context of congenital diaphragmatic hernia. In our laboratory, we use advanced cell and molecular biology techniques and small animal physiology techniques in our investigative efforts. Students in thhe laboratory will have the opportunity to become engaged in a basic science laboratory exploring a clinical problem that presently has no answers.

|Seema Garg||Ophthalmologyemail@example.com||Retinal imaging, diabetic retinopathy telemedical screening, ophthalmic genetics||I have been interested in the applications of technology in medicine for many years. I have piloted the diabetic retinopathy (DR) telemedicine program at UNC in which we have increased DR screening rates from 30% to 70%. I am also interested in novel retinal imaging modalities. I am currently supervising research with a novel imaging device called the retinal oximeter. It is a non-invasive method based on a traditional fundus camera, to measure retinal oxygen saturation in retinal vessels based on the differential light absorbency of oxygenated and deoxygenated hemoglobin. At UNC, our research group has produced a normative database of retinal oximetry, studied the repeatability of the instrument and has evaluated this technology in a variety of disease states such as diabetic retinopathy and radiation retinopathy. Diabetic retinopathy is a potentially blinding microvascular disease characterized by progressive retinal ischemia. Our research group is studying the relationship of retinal oximetry and fluorescein angiography in order to characterize the retinal oxygenation status in various stages of diabetic retinopathy. If we can determine a non-invasive marker for pre-clinical diabetic retinopathy such as decreased retinal oxygenation, retinal oximetry may potentially serve as a screening device for patients who are at higher risk for retinopathy. I am also interested in hereditary eye disease. Nearly half of the patients in our ophthalmology/genetics clinic have negative clinical genetic testing. Our goal is to employ emerging genetic technologies such as next-generation whole-exome sequencing to determine a molecular diagnosis for these patients.|

|Seth Noar||Otherfirstname.lastname@example.org||Indoor Tanning among Adolescents and Young Adults||It is a well-established fact in the scientific community that ultraviolet (UV) radiation, including that from artificial sources such as tanning beds, causes skin cancer. Skin cancer is the most common type of cancer in the United States and affects more than two million Americans. The International Association for Research on Cancer found that people who engage in indoor tanning before the age of 30 are 75% more likely to develop melanoma, the deadliest form of skin cancer. Despite this, nearly two million Americans participate in indoor tanning every day.
Dr. Noar recently conducted a study among sorority women at UNC-CH to assess the attitudes and beliefs associated with indoor tanning. This first study is currently being validated via an additional study at Wake Forest University. The proposed survey research will examine adolescents â€“ a critical population in this area - in terms of their indoor tanning behavior with regards to the social cognitive theory constructs of outcome expectations and self-efficacy (temptations). These theoretical factors have been found to be highly predictive of other health and risk behaviors, but limited research applying these theoretical concepts to indoor tanning currently exists. This research will lay the groundwork for the development and evaluation of health communication interventions to encourage young women to not participate in indoor tanning.

|Silvia Ramos||Obstetrics & Gynecologyfirstname.lastname@example.org||Female Infertility||I have developed a unique mouse model of female sterility that may represent a significant proportion of unexplained infertility seen in women. The DeltaN-Zfp36l2 mouse model is linked to the disruption of the earliest stages of embryogenesis the only one of its kind demonstrating the involvement of an mRNA destabilizing protein in the progression of the embryo beyond the two-cell stage (Ramos et al, Development 2004). Zinc Finger Protein 36 Like 2, ZFP36L2, belongs to the TTP (ZFP36) family of proteins that destabilize certain mRNA containing ARE elements. Although TTP has been involved in modulation of inflammatory and autoimmune responses; ZFP36L2, which is ubiquitously expressed, affects only the earliest stages of embryogenesis (Ramos et al, 2004) and hematopoiesis (Stumpo et al, 2009). Therefore it is my goal to investigate the mechanism which ZFP36L2 leads to female infertility. This basic research will lead to molecular insights on this important condition for which no direct diagnosis method is currently available.|
|Stefanie Sarantopoulos||Hematology & Oncologyemail@example.com||B-cell Pathology in Patients with Chronic Graft versus Host Disease||Adult hematopoietic stem/bone marrow transplantation (HSCT) involves the transfer of donor cells to patients/recipients suffering from leukemia, lymphoma or other blood/bone marrow cancers. Our primary laboratory interest is study of the significant immune pathology that develops in patients who have undergone HSCT. While HSCT offers the possibility of cure for many patients with hematologic diseases, the full potential of HSCT has not been realized because of transplant-related complications. Chronic GVHD has an adverse impact on survival that has not improved significantly over the last 30 years. Targeted therapy for chronic GVHD has been difficult to develop due to limited understanding of immunopathologic mechanisms in human cGVHD. Our lab has shown that B cells play a role in cGVHD, but the mechanisms that promote and sustain B cell involvement have not been elucidated. These studies of human B cells will elucidate immune tolerance mechanisms. Better understanding of chronic GVHD will result in novel targeted therapeutic agents so that we can decrease morbidity and mortality in our HSCT patients.
The summer student would work with a post-doctoral fellow or research assistant on a project aiming to identify activated B cells in lesional tissue in patients with chronic GVHD. The following techniques will be employed: 1) ELISA to determine presence of BAFF and autoantigen(s) in HSCT patient plasma 2) Analysis of patient skin by immunohistochemistry for specific B-cell subsets and 3) Flow cytometry of patient whole blood, examining B-cell subsets.

|Stergios Moschos||Hematology & Oncologyfirstname.lastname@example.org||Understanding the Biology of Melanoma Brain Metastases||Over the last 2 years my research focus has been to study the biology of melanoma brain metastases, in hopes to understand why melanoma is the cancer that most frequently goes to the brain, why it has the highest propensity to bleed, and why its prognosis is poor in general. The long term focus is to develop rational therapies for this disease site group, the incidence of which will exponentially rise over the next few years given the advent of new effective, recently F.D.A-approved therapies for metastatic melanoma (e.g. vemurafenib, ipilimumab).
As part of this effort, and during the last 2 years of my tenure as an Assistant Professor at the University of Pittsburgh SPORE-funded Melanoma program I established a tissue database that consists of 101 formalin-fixed paraffin-embedded tumor blocks obtained from patients who underwent craniotomy for melanoma brain metastases. Following detailed histopathologic, whole genome expression, and immunohistochemical analysis, we identified that high immune infiltrate, low intratumoral hemorrhage, and high melanin are associated with prolonge survival. In addition, genes involved in Notch, Wnt, HIF1alpha, G-protein coupled receptor, and Tubby signaling are associated with worse prognosis.
My plan is to validate these findings in the UNC-CH melanoma brain metastases cohort and in addition perform whole genome exon sequencing on brain melanoma metastases, extracranial metastases, and primary melanoma from the same patients to identify metastasis-specific genes that are distinct from ones that have already described (B-Raf, N-Ras).

We hypothesize that obesity gives rise to biologically and metabolically different cancers than those that arise in a non-obese environment; and thus, obesity-driven cancers may have unique vulnerabilities that could be targeted for treatment. In this pursuit, I have investigated many novel targeted therapies for the treatment of obesity-driven ovarian and endometrial cancer, including mTOR inhibitors, arsenic, a human monoclonal antibody to the insulin growth factor-1 receptor (IGF-1R), soy, genistein, cox-2 inhibitors, statins and metformin. My pre-clinical work has led to several investigator-initiated clinical trials, including pre-operative window studies of metformin and atorvastatin in obese endometrial cancer patients, a pilot study of meformin for the treatment of endometrial hyperplasia, a phase II trial of metformin in combination with the levonorgestrel-intrauterine device in endometrial hyperplasia/cancer patients, a phase II trial of metformin (plus paclitaxel/carboplatin) in newly diagnosed ovarian cancer patients and a randomized phase II/III evaluation of paclitaxel/carboplatin/metformin versus paclitaxel/carboplatin/placebo in advanced and recurrent endometrial cancer patients.|

Providing care to these patients is a priority of the NIDDK.
Aims: This survey will attempt to answer the following questions:
1. How do people with ABL cope? Preliminary data suggests some maladaptive ways of coping such as not eating before going out.
2. Does severity of ABL and its impact on quality of life influence how people cope with ABL?
3. Does coping style influence whether people consult for ABL?
Methods: An internet survey will collect data from approximately 200 people with ABL. This database will be completed before May 2016. Medical student will be mentored in analyzing the data, preparing an abstract for submission to the annual meeting of the Am Gastroenterol Assoc, and preparing a manuscript for publication in a journal.

There are several treatment methods that are recommended for the acute management of these injuries. Many of them are outdated and scientifically unsound. As a result, this clinical scenario continues to represent a therapeutic dilemma. This systematic review will highlight the success rates of various treatment options and the dispel many of the myths that are associated with the management of these injuries. We plan to survey practitioners in otolaryngology/head and neck surgery as well as experts in auricular reconstruction about their current treatment patterns. The major goal of this project will be to recommend practice guidelines for this specific injury.
This will be an ideal study for medical students. It will involve an in-depth review of the literature, creating a survey for practitioners as well as experts, gathering and tabulating data, and putting together a systematic review. As the mentor I will be working with a student weekly in order to provide guidance for the study, survey, and manuscript. My associate, Dr. Madison Clark will also be involved and will also be available as a mentor. We would anticipate that this will lead to a podium presentation at a national meeting as well as a publication in one of the major otolaryngology/head and neck surgery or facial plastic and reconstructive surgery journals.

|Jean-Claude Mwanza||Ophthalmology||Clinical||Noemail@example.com||Comparison of Visual Field Using a Tablet-based Perimeter and Humphrey Field Analyzer||BACGROUND
Glaucoma is the second case of blindness worldwide. It is a slow progressive neurodegenerative disorder affecting the optic nerve. It is characterized by the dysfunction and then death of retinal ganglion cells (RGCs) and their axons, leading to morphological changes to the optic nerve head (ONH) and visual field deficits. If left untreated or inadequately treated glaucoma slowly leads to irreversible blindness. Both medical and surgical treatment are effective in controlling intraocular pressure (the main risk factor) in most cases and slow considerably the progression of the disease and therefore prevent visual impairment. In the United States, the number of people with glaucoma rose from 2.2 million to 2.7 million from 2000 to 2010, with projections to increase to 4 million in 2030 and 6.3 million in 2050. The prevalence of glaucoma varies across regions, but it is highest in Africa[2-6] More importantly, of all people with glaucoma in the United States, approximately 50% are undiagnosed. Such rates are even higher in low-income countries. In sub-Saharan Africa for example, 87.1% to 98.5% of people with glaucoma diagnosed in population-based surveys were not aware that they have it.[5-11] Thus the key to preventing visual impairment and its consequences such as falls, bad quality of life, is early detection of glaucoma, particularly in populations at risk.
There have been several attempts to develop glaucoma screening various methods such as those focusing on intraocular pressure measurement, appearance of the optic nerve head or questionnaires, but those methods proved to be less sensitive and less specific. Because glaucomatous visual field deficits are specific, a screening method based on visual field testing may help detect glaucoma in population at risk.
However such a screening cannot be performed using the method of visual field testing used in the clinical setting (Humphrey Field Analyzer, HFA) because it is time-consuming. A good method screening method should be inexpensive, portable, easy to use, administer, and interpret, and comfortable for the subjects.
TestFlight is a tablet-based application called MRF for Melbourne rapid Field on the iPad platform that has been developed with the ultimate aim of facilitating perimetry outside the traditional clinical setting. It features a blind spot monitor, reliability tests, and fast thresholding using Bates logic. It provides the same testing modes and outputs as the HFA. In addition to the test pattern used on HFA (which allows comparison), it also has its own specific testing pattern with more test points. It is easy to use, it only take about 2 minutes per eye. Prior to using it in population screening, it needs to be tested in clinic to see how it performs in real glaucoma patients
1) To compare the perimetric results from the iPad-based app (Melbourne Rapid Fields or MRF) to those of HVF 24-2 SITA Standard testing mode.
2) To evaluate accuracy of the MRF, an iPad app, for performing perimetric screening
3) To correlate the results of MRF and HFA.
Consecutive patients attending their clinical appointment in the glaucoma clinic and scheduled for HFA will be recruited for the study. They will qualify for the study if they are at least 18 years old, have diagnosed with glaucoma in at least one eye, are willing to perform the tablet-based visual field prior of following the HFA, have best corrected visual acuity of 20/40 per qualifying eye. Patients with diabetic proliferative retinopathy, neurological disorders, or those on medication that may affect visual field will be excluded. A total of 80 patients with glaucoma at different stages (early, moderate, advanced) will be enrolled in the stud. Each patients will undergo both tests the same day, in no particular order although we prefer MRF first while they are waiting for HFA. 30 0f these patients will also undergo spectral domain optical coherence tomography (OCT) of the ONH and the macula
Because HVF testing is usually performed once a year, patients will be perform both tests a year later the day HFA is scheduled.
Study parameters on both tests will include 1) mean deviation, 2) pattern standard deviation, 3) number of missed locations, 4) false positive rates, 5) false negative rates, 6) time to complete the test, 7) the number of points worse than 5% probability level of total deviation map.
The analysis will include comparison of the study parameters from the two tests (paired t-test) and correlating them (Pearson correlation). Person correction of deviation and pattern standard deviation with OCT parameters ( retinal nerve fiber layer thickness, ganglion cell-inner plexiform layer thickness, rim area, vertical cup-t-disc ratio) will also be performed.

I specifically aim to develop prebiotic and probiotic interventions as alternatives to traditional treatments for microbiota-health related conditions, and to advance microbiota-based health surveillance methods.
Prebiotics are resistant to digestion in the upper gastrointestinal tract, arrive at the colon intact and increase the abundance of specific primary and secondary degraders with the final result of an expanded probiome, beneficial members of the intestinal microbiota. We have shown that pure prebiotics modulate gut microbiome composition and activity in humans and animal models increasing gut beneficial bacteria. In humans, the modulatory influence of pure galactooligosaccharides significantly improved clinical outcomes for lactose digestion and tolerance. Our current research investigate prebiotics as gut microbiome modulators of age-associated diseases to identify mechanisms of prebiosis in vulnerable populations.
Probiotics can reduce the risk of common infectious and acute diarrheal illnesses, and can be an alternative to treatments with antibiotics or anti-inflammatory drugs. Large-scale microbiome studies have established that most of the bacterial diversity contained in the gastrointestinal tract is represented at the strain level. Hence genomic and physiological characterization of isolates of probiotic potential is essential to determine unique attributes that will allow for personalized interventions. Our lab is conducting functional genomics studies to determine genetic components contributing to probiotic survival in the gastrointestinal tract and capability to metabolize prebiotics.
|Crystal Wiley Cene||Medicine||Translational||Yesfirstname.lastname@example.org||Patient and Family Engagement in Heart Failure Care||Close to 40% of older adults in general and heart failure patients specifically, are accompanied to medical visits by a family member. These family members are very influential in supporting patients as they manage their heart failure, yet their contribution is often under-appreciated by health care providers. The quality of communication between patients, family members, and health care providers greatly influences how well heart failure patients take care of their illness at home (i.e. self-management). Our prior study demonstrated, using analysis of audiotaped data from actual visits, that heart failure patients and family members are not actively engaged during visits, as indicated by asking fewer questions and giving less information. This is disturbing given known knowledge deficits among heart failure patients and family members about heart failure.
Strategies such as pre-visit prompt lists can enhance engagement by encouraging patients and family members to ask relevant questions and discuss sensitive topics with health care providers. A prompt list is a structured list of questions or topics related to illness, treatment, and support that is developed from interviews with patients, family members, and health care providers. Prompt lists are completed by patients and family members before a visit. Prompt lists have been shown to increase the number and relevance of questions asked by patients and family members. However, several important gaps in the literature exist. First, the effect of prompt lists on self- management behaviors has not been tested. Second, few studies have used them with family members. Lastly, prompt lists have not been tested in heart failure patients. Most of the research on their use has been conducted in cancer patients facing oncology-specific clinical decisions. To address these gaps, we developed a pre-visit prompt list for use with heart failure patient-family member dyads (using cognitive interviews). We are currently conducting a pilot randomized trial in 30 heart failure patient-family dyads. We randomize participants to receive the prompt list vs. usual care and assess feasibility, acceptability, and effects on behavioral outcomes.
A student participating in this project would have the opportunity to assist with: data collection in the clinic and writing abstracts and manuscripts to be submitted for publication (on which the student could be a co-author). The student could also have the opportunity to work on other related projects lead by Dr. Cene focused on developing practical tools to enhance engagement among patients with multiple chronic conditions and their family members.

This trial is being conducted at 10 centers with a wide geographic reach and patient diversity to optimize generalizability.

2. Phase II Study of Nicotinamide Supplementation in Early Onset Preeclampsia. Nicotinamide (vitamin B3-amide) is a nontoxic water-soluble amide of vitamin B3 that lowers blood pressure and mortality in a mouse model of preeclampsia, probably via its inhibitory action on ADPR-cyclase. We are testing the ability of nicotinamide to lower maternal blood pressure and reduce risk of development of severe hypertension in women with early-onset preeclampsia. Such effects would demonstrate feasibility of studying nicotinamide as a therapeutic in early onset precclampsia to prolong gestation and reduce medically indicated preterm birth..
