Mechanisms By Which Dietary Ellagic Acid Attenuates Obesity And Obesity-Mediated Metabolic Complications, Inhae Kang

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Ellagic acid (EA) is a polyphenol found in various fruits and plants, such as berries, pomegranates, muscadine grapes, nuts and bark of oak tree. EA has been known to exhibit anti-inflammatory and anti-proliferative effects in various types of cancer. However, little is known about the effects of EA on obesity. Herein, 1) the lipid-lowering role of EA was identified in primary human adipose stem cells (hASCs) and human hepatoma Huh7 cells; 2) the molecular mechanisms by which EA attenuates adipogenesis by epigenetic modification were identified; 3) the effects of EA on high fat and high sucrose-mediated obesity was …

Prenatal Exposure To Perfluoroalkyl Acids And Serum Testosterone Concentrations At 15 Years Of Age In Female Alspac Study Participants, Mildred Maisonet, Antonia M. Calafat, Michele Marcus, Jouni J.K. Jaakkola, Hany Lashen

ETSU Faculty Works

Background: Exposure to perfluorooctane sulfonic acid (PFOS) or to perfluorooctanoic acid (PFOA) increases mouse and human peroxisome proliferator–activated receptor alpha (PPARα) subtype activity, which influences lipid metabolism. Because cholesterol is the substrate from which testosterone is synthesized, exposure to these substances has the potential to alter testosterone concentrations.

Objectives: We explored associations of total testosterone and sex hormone–binding globulin (SHBG) concentrations at age 15 years with prenatal exposures to PFOS, PFOA, perfluorohexane sulfonic acid (PFHxS), and perfluoronanoic acid (PFNA) in females.

Methods: Prenatal concentrations of the perfluoroalkyl acids (PFAAs) were measured in serum collected from pregnant mothers at enrollment (1991–1992) …

Disease-Management In Family Medicine Clinics Through The Addition Of A Health Coach: A Pilot Study, Crystal Y. Cichon, Jessica J.F. Kram, Tiffany A. Mullen, Pamela Voelkers, Kristin J. Magliocco, Kiley A. Bernhard, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

Background: In the United States, more than 80% of health care spending is focused on the management of chronic illnesses such as hypertension, diabetes and hyperlipidemia. Controlling these chronic diseases can lead to better health outcomes and decrease the number of preventable deaths. Patient self-management has shown to improve clinical outcomes. In a primary care setting, a multidisciplinary approach can more effectively educate patients on improving their health.

Purpose: To assess the impact of a health coach in a primary care setting as it relates to clinical outcomes.

Methods: Patients from two Aurora family medicine clinics were referred to a …

Chronic Illness Management In Teams Of Urban Multidisciplinary Scholars (Cimtums) –– Part Ii, John R. Brill, Diane Ames, Christine B. Groth, Helen Yu

Journal of Patient-Centered Research and Reviews

Background: Diabetes is a major contributor to morbidity and mortality as well as the single most expensive health care condition in the world. Numerous interventions have attempted to improve control of this disorder and reduce its complications. Traditional care for diabetes centers on an individual clinician. More recently, recognition of the central role of the patient has come into vogue. Payors, including Medicare, now cover up to 13 hours of diabetes self-management and education programs annually. Patient-centered medical home efforts add an aspect of inclusiveness, but retain a medical focus and are being increasingly advocated and trained. To date, no …

Enhanced Fitness And Renal Function In Type 2 Diabetes., Eric S. Nylen, S. M. Gandhi, Raya E. Kheirbek, Peter Kokkinos

Medicine Faculty Publications

Aims

To investigate the renal effects of fitness in people with diabetes with mild renal dysfunction.

Methods

The effect of a 12-week exercise programme on estimated GFR in 128 people with diabetes was evaluated.

Results

All cardiometabolic variables improved after 12 weeks of supervised exercise. Although there was a modest 3.9% increase in estimated GFR from baseline in the 128 people who completed the study, those with baseline chronic kidney disease stages 2 and 3 were found to have significant (6 and 12%, respectively; p < 0.01) improvements in post-exercise estimated GFR. Moreover, 42% of the people with chronic kidney disease stage 3 improved to chronic kidney disease stage 2 after the intervention.

Conclusion

Short-term exercise improves renal function in those with more moderate baseline chronic kidney disease. …

New-Onset Diabetes Mellitus With Exposure To Ledipasvir And Sofosbuvir., Resmi Premji, Nira Roopnarinesingh, Nazia Qazi, Eric S. Nylen

Medicine Faculty Publications

The combination therapy of ledipasvir/sofosbuvir was approved by the Food and Drug Administration in 2014 for the treatment of chronic hepatitis C. Although hyperglycemia is not well known to occur with its use, we present 2 cases of new-onset diabetes mellitus and a review of the literature suggesting an adverse event association. In the first patient with HIV, we postulate that ledipasvir/sofosbuvir increased the levels of tenofovir and thereby potentiated hyperglycemia. In the second case of a patient with prediabetes, ledipasvir/sofosbuvir appeared to increase insulin resistance. A literature review further supported an association of hyperglycemia and the use of ledipasvir/sofosbuvir. …

Integrating Meal And Exercise Into Personalized Glucoregulation Models: Metabolic Dynamics And Diabetic Athletes, Sofie Schunk

Master's Theses (2009 -)

Diabetes affects nearly 26 million Americans, according to the American Diabetes Association, with as many as three million Americans who have Type 1 Diabetes (ADA, 2015). Type 1 Diabetes (T1D) is autoimmune and characterized by little to no insulin production whereas Type 2 Diabetes (T2D) concerns insulin resistance and inability to use produced insulin. Factors contributing to current diabetes management and regulation include exercise type, daily movement activities, and distinct tissue compartment metabolism, each challenging to model in a robust and comprehensive manner. Past models are highly limited in regard to exercise and varying glucose fluctuations dependent on type, intensity, …

Intra-Individual Consistency In Endocrine Profiles Across Successive Pregnancies, Molly Fox, Curt A. Sandman, Elyssia Poggi Davis, Laura M. Glynn

Psychology Faculty Articles and Research

Context: It is yet unknown how similar women’s hormone levels are during successive pregnancies, and very little is known about the degree to which siblings experience similar prenatal environments. Given the importance of understanding how women’s reproductive life-histories exert cumulative effects on health via hormone exposure, and the importance of understanding how fetal programming via endocrine signaling affects sibling trait concordance, here we address this important lacuna in the literature.

Objective: To investigate how consistent are women’s hormone profiles across two successive pregnancies.

Design and Main Outcome Measures: This longitudinal, prospective study followed a cohort of 28 …

Treatment-Induced Changes In Plasma Adiponectin Do Not Reduce Urinary Albumin Excretion In The Diabetes Prevention Program Cohort., Kieren J Mather, Qing Pan, William C Knowler, Tohru Funahashi, George A Bray, Richard Arakaki, Bonita Falkner, Kumar Sharma, Barry J. Goldstein

Department of Medicine Faculty Papers

BACKGROUND AND OBJECTIVES: Molecular data suggests that adiponectin may directly regulate urinary albumin excretion. In the Diabetes Prevention Program (DPP) we measured adiponectin and albuminuria before and after intervention, and we previously reported increases in adiponectin with interventions. Here we have used the DPP dataset to test the hypothesis that treatment-related increases in adiponectin may reduce albuminuria in obesity.

DESIGN, SETTING, PARTICIPANTS AND METHODS: We evaluated cross-sectional correlations between plasma adiponectin and urinary albumin excretion at baseline, and the relationship of treatment-related changes in adiponectin and albuminuria. Baseline and follow-up urine albumin to creatinine ratios (ACR (albumin to creatinine ratio)) …

Unusual Presentation With Polymenorrhagia And Markedly High 17-Hydroxy Progesterone Levels In A Lady With Non-Classic Congenital Adrenal Hyperplasia., Azra Rizwan, Marium Hayat

Department of Medicine

Congenital adrenal hyperplasia is generally associated with oligo-amenorrhea, and its presentation with polymenorrhagia is rare. Here we present a case of an Asian female who presented with polymenorrhagia since menarche, increased body hair growth and enlargement of clitoris for 7-8 years. Examination revealed a normal Body Mass Index, moderate hirsutism, Tanner 5 breasts and significant clitoromegaly. Serum testosterone and 17-hydroxyprogesterone levels were elevated. Ultrasonography revealed normal adrenal glands and polycystic ovaries. adrenocorticotropic hormone stimulation test uncovered borderline cortisol deficiency. Oral dexamethasone was commenced and six months later, she showed improvement though there was no change in hirsutism or clitoromegaly. The …

Caffeine Consumption Contributes To Skin Intrinsic Fluorescence In Type 1 Diabetes., Karen M Eny, Trevor J Orchard, Rachel Grace Miller, John Maynard, Denis M Grant, Tina Costacou, Patricia A. Cleary, Barbara H Braffett, Andrew D Paterson, Dcct/Edic Research Group

GW Biostatistics Center

Background: A variant (rs1495741) in the gene for the N-acetyltransferase 2 (NAT2) protein is associated with skin intrinsic fluorescence (SIF), a noninvasive measure of advanced glycation end products and other fluorophores in the skin. Because NAT2 is involved in caffeine metabolism, we aimed to determine whether caffeine consumption is associated with SIF and whether rs1495741 is associated with SIF independently of caffeine.

Materials and Methods: SIF was measured in 1,181 participants with type 1 diabetes from the Epidemiology of Diabetes Interventions and Complications study. Two measures of SIF were used: SIF1, using a 375-nm excitation light-emitting diode (LED), and …

Obesity Early In Adulthood Increases Risk But Does Not Affect Outcomes Of Hepatocellular Carcinoma, Manal M. Hassan, Reham Abdel-Wahab, Ahmed Kaseb, Ahmed Shalaby, Alexandria Phan, Hashem El-Serag, Ernest Hawk, Jeff Morris, Kanwal Pratap Singh Raghav, Ju-Seog Lee, Jean-Nicolas Vauthey, Gehan Bortus, Harrys Torres, Christopher Amos, Robert Wolff, Donghui Li

Despite the significant association between obesity and several cancers, it has been difficult to establish an association between obesity and hepatocellular carcinoma (HCC). Patients with HCC often have ascites, making it a challenge to accurately determine body mass index (BMI), and many factors contribute to the development of HCC. We performed a case–control study to investigate whether obesity early in adulthood affects risk, age of onset, or outcomes of patients with HCC.

Increasing Adipocyte Lipoprotein Lipase Improves Glucose Metabolism In High Fat Diet-Induced Obesity, R. Grace Walton, Beibei Zhu, Resat Unal, Michael Spencer, Manjula Sunkara, Andrew J. Morris, Richard Charnigo, Wendy S. Katz, Alan Daugherty, Deborah A. Howatt, Philip A. Kern, Brian S. Finlin

Barnstable Brown Diabetes Center Faculty Publications

Lipid accumulation in liver and skeletal muscle contributes to co-morbidities associated with diabetes and obesity. We made a transgenic mouse in which the adiponectin (Adipoq) promoter drives expression of lipoprotein lipase (LPL) in adipocytes to potentially increase adipose tissue lipid storage. These mice (Adipoq-LPL) have improved glucose and insulin tolerance as well as increased energy expenditure when challenged with a high fat diet (HFD). To identify the mechanism(s) involved, we determined whether the Adipoq-LPL mice diverted dietary lipid to adipose tissue to reduce peripheral lipotoxicity, but we found no evidence for this. Instead, characterization …

Journal of Patient-Centered Research and Reviews

Purpose

Metabolic syndrome is a set of metabolic risk factors associated with increased risk of developing cardiovascular disease and type 2 diabetes mellitus. We retrospectively evaluated the effectiveness of a lifestyle modification program (Heart WATCH) geared toward reducing development of chronic disease in women deemed at risk for metabolic syndrome, prediabetes and/or cardiovascular disease.

Methods

Our institution’s Heart WATCH program consists of screening sessions with a multidisciplinary team (physician/nurse, nutritionist and psychologist), a minimum of three visits with a nurse practitioner and weekly follow-up phone calls for a 14-week period. Sociodemographic variables were obtained at initial visit. Biometric testing indices …

Diabetes Self-Management Education For Adolescent Patients: The Importance Of A Developmentally Sensitive Approach, Laura Mumme

Senior Honors Theses

The attention of healthcare providers to the developmental level of adolescent patients with type one diabetes (T1D) maximizes effective patient education and glycemic control. Due to the dynamic changes that occur in the mind and body during adolescence, self-care for adolescent T1D patients is overwhelming as it envelopes activities of everyday life. The disease process and the unique aspects of adolescence in relation to T1D are important for caregivers to consider. Developmentally appropriate teaching during the initial onset of the disease must inform the patient and the patient’s family of the basics of the disease process and the daily care …

Management Of The Hospitalized Transplant Patient., Brian P. Boerner, Vijay Shivaswamy, Whitney Goldner, Jennifer Larsen

Journal Articles: Diabetes, Endocrinology & Metabolism

Significant hyperglycemia is commonly observed immediately after solid organ and bone marrow transplant as well as with subsequent hospitalizations. Surgery and procedures are well known to cause pain and stress leading to secretion of cytokines and other hormones known to aggravate insulin action. Immunosuppression required for transplant and preexisting risk are also major factors. Glucose control improves outcomes for all hospitalized patients, including transplant patients, but is often more challenging to achieve because of frequent and sometimes unpredictable changes in immunosuppression doses, renal function, and nutrition. As a result, risk of hypoglycemia can be greater in this patient group when …

Supporting Practices To Adopt Registry-Based Care (Sparc): Protocol For A Randomized Controlled Trial, Rebeccar S. Etz, Rosalind E. Keith, Anna M. Matemick, Karen L. Stein, Roy T. Sabo, Melissa S. Hayes, Purvi Sevak, John Holland, Jesse C. Crosson

Publications and Research

Background: Diabetes is predicted to increase in incidence by 42% from 1995 to 2025. Although most adults with diabetes seek care from primary care practices, adherence to treatment guidelines in these settings is not optimal. Many practices lack the infrastructure to monitor patient adherence to recommended treatment and are slow to implement changes critical for effective management of patients with chronic conditions. Supporting Practices to Adopt Registry-Based Care (SPARC) will evaluate effectiveness and sustainability of a low-cost intervention designed to support work process change in primary care practices and enhance focus on population-based care through implementation of a diabetes …
