Roux-En-Y Gastric Bypass Is Associated With Increased Intestinal Glucose Uptake In Humans, Florina Corpodean, Maryam Naseri, Michael Kachmar, Julia St Amant, Denis P. Blondin, Owen T. Carmichael, Vance L. Albaugh

School of Medicine Faculty Publications

CONTEXT: In animal models, Roux-en-Y gastric bypass (RYGB) is associated with increased Roux limb intestinal glucose uptake that may contribute to early metabolic benefits, though prospective clinical studies are lacking. OBJECTIVE: The present study aimed to test the hypothesis that Roux limb glucose uptake would increase relative to baseline in a cohort of patients undergoing RYGB. METHODS: RYGB patients underwent preoperative baseline, and 3- and 6-month positron emission tomography/computed tomography postoperative imaging. Maximum and mean standardized uptake values (SUV) were measured from the following predefined regions of interest: cecum, hepatic flexure, splenic flexure, sigmoid colon, duodenal bulb, Roux limb, and …

Hyperbaric Oxygen Therapy In The Atls/Acls Resuscitative Management Of Acutely Ill Or Severely Injured Patients With Severe Anemia: A Review, Keith W. Van Meter

School of Medicine Faculty Publications

For short periods, even without the presence of red blood cells, hyperbaric oxygen can safely allow plasma to meet the oxygen delivery requirements of a human at rest. By this means, hyperbaric oxygen, in special instances, may be used as a bridge to lessen blood transfusion requirements. Hyperbaric oxygen, applied intermittently, can readily avert oxygen toxicity while meeting the body's oxygen requirements. In acute injury or illness, accumulated oxygen debt is shadowed by adenosine triphosphate debt. Hyperbaric oxygen efficiently provides superior diffusion distances of oxygen in tissue compared to those provided by breathing normobaric oxygen. Intermittent application of hyperbaric oxygen …

An Aerobic Exercise Intervention To Improve Metabolic Health Among People Living With Hiv With At-Risk Alcohol Use: The Alive-Ex Research Study Protocol, Liz Simon, Stefany D. Primeaux, Danielle E. Levitt, Brianna Bourgeois, Neil M. Johannsen, Adrianna Peters, Jameel Ahmed, Richard H. Marshall, Alexandra H. Fairchild, Tekeda F. Ferguson, Patricia E. Molina

Background: Effective antiretroviral therapy (ART) in people living with HIV (PLWH) has improved life expectancy and increased risk of age-associated cardiometabolic comorbidities. At-risk alcohol use is more frequent among PLWH and increases the risk of health challenges. PLWH with at-risk alcohol use are more likely to meet criteria for prediabetes/diabetes and this is associated with impaired whole-body glucose-insulin dynamics. Methods: The Alcohol & Metabolic Comorbidities in PLWH: Evidence Driven Interventions Study (ALIVE-Ex Study, NCT03299205) is a longitudinal, prospective, interventional study to determine the effects of an aerobic exercise protocol on improving dysglycemia among PLWH with at-risk alcohol use. The intervention …

Sugar-Sweetened Beverages Intake, Abdominal Obesity, And Inflammation Among Us Adults Without And With Prediabetes—An Nhanes Study, Wei Ting Lin, Yu Hsiang Kao, Mirandy S. Li, Ting Luo, Hui Yi Lin, Chien Hung Lee, David W. Seal, Chih Yang Hu, Lei Shih Chen, Tung-Sung Tseng

School of Public Health Faculty Publications

Excessive sugar-sweetened beverages (SSB) consumption and abdominal obesity have been independently linked to numerous disorders, including diabetes and elevated C-reactive protein (CRP). This study aimed to explore the association between SSB intake, abdominal obesity, and inflammation in normal and prediabetic adults. Sugar intake from SSBs was calculated from 24-h dietary recalls and further classified into non-, medium-, and high-intake. The status of non- and prediabetes was identified based on hemoglobin A1c level. All analyses were performed under a survey module with appropriate sampling weights to control for the complex survey design. A total of 5250 eligible adults without diabetes were …

Identification And Characterization Of Butyrate-Producing Species In The Human Gut Microbiome, Grace Maline

Theses/Capstones/Creative Projects

Inflammatory Bowel Diseases (IBD) including ulcerative colitis, indeterminate colitis, and Crohn’s disease are increasingly common conditions that places a high physical and financial burden on individuals and global healthcare systems. Though many treatments exist for these conditions, their unpredictable nature and causation make them difficult to manage across the variety of IBD patients. Additionally, many of these treatments come with undesirable side effects or modes of delivery. Therefore, it is worthwhile to explore the use of Short Chain Fatty Acids (SCFAs) such as butyrate whose affects in the human gut include decreased inflammation and decreased risk of colorectal cancer. As …

Glycosaminoglycan Lyases In The Preparation Of Oligosaccharides, Alhumaidi B. Alabbas

Theses and Dissertations

Glycosaminoglycans are heterogeneous polysaccharides that mediate important biological functions. There has been considerable interest in deciphering the precise GAG sequences that are responsible for protein interactions. In fact, several GAG oligosaccharides have been discovered to date as targeting proteins with higher level of specificity. Yet, it has been difficult to develop GAG oligosaccharides as drugs. One of the key reasons for this state of art is that GAG synthesis is extremely challenging and is highly structure-specific. Thus, much of the biology and pharmacology of GAG remains unknown and unexploited to date.

An alternative approach is to prepare GAG oligosaccharides using …
