Gut Symbionts Alleviate Mash Through A Secondary Bile Acid Biosynthetic Pathway

Journal Articles

The gut microbiota has been found to play an important role in the progression of metabolic dysfunction-associated steatohepatitis (MASH), but the mechanisms have not been established. Here, by developing a click-chemistry-based enrichment strategy, we identified several microbial-derived bile acids, including the previously uncharacterized 3-succinylated cholic acid (3-sucCA), which is negatively correlated with liver damage in patients with liver-tissue-biopsy-proven metabolic dysfunction-associated fatty liver disease (MAFLD). By screening human bacterial isolates, we identified Bacteroides uniformis strains as effective producers of 3-sucCA both in vitro and in vivo. By activity-based protein purification and identification, we identified an enzyme annotated as β-lactamase in B. …

Gaining Glycemic Control In Patients With Uncontrolled Type 2 Diabetes In Rural Health, Demetric Childs-Hicks

Student Scholarly Projects

Practice Problem: Diabetes is a significant global healthcare problem. The number of individuals diagnosed with Type 2 Diabetes (T2D) is alarmingly high and the numbers are steadily increasing. Because of various barriers, individuals living in rural communities are at greater risk of having uncontrolled T2D.

PICOT: The PICOT question that guided this project was “Will patients with uncontrolled T2D in rural health have better control of their glucose levels when using telephone or web-based monitoring by healthcare providers than patients with uncontrolled T2D in rural health who do not use technology to achieve glycemic control as evidenced by lower pre-prandial …

Most Elderly Patients With Subclinical Hypothyroidism Do Not Need To Be Treated

Faculty and Staff Publications

Whether subclinical hypothyroidism should be treated in elderly patients (≥ 65 years) is controversial. The authors argue for a personalized, wait-and-see approach rather than universal treatment, pointing out that randomized clinical trials have not shown that levothyroxine treatment makes any difference in terms of hard clinical end points, quality of life, or hypothyroid symptom relief in elderly patients with this condition.

The New Era Of Aspiration Risk: The Dilemma Of Glp-1 Receptor Agonists, Andrew Goyen, Jack Madden

Journal of Perioperative Nursing

There is a new wave of aspiration risk heading towards our operating theatres in the coming years. The popular weight loss drugs, glucagon-like peptide (GLP-1) receptor agonists, are providing us with new dilemmas in fasting guidelines and airway management. What does the anaesthetic team need to know?

American Society For Metabolic And Bariatric Surgery Review Of The Body Mass Index, Vance L. Albaugh

School of Medicine Faculty Publications

The body mass index was first described almost 200 years ago and has since been used as a measure of obesity. This review describes the history, advantages, disadvantages, and alternatives to the body mass index in the care of the metabolic and bariatric surgical patient.

The Effect Of Alcohol Prep Pads And Blood Drop Number On Capillary Blood Glucose Values, Joanna Foos

Honors Theses and Capstones

Capillary blood glucose monitoring is a common nursing procedure. However, no consensus exists regarding which drop of blood to test (drop 1 vs. drop 2) and whether using alcohol pads to prepare the fingertip affects blood glucose values. The purpose of this study was to evaluate the impact of these factors and contribute to the development of evidence-based nursing protocols for capillary blood glucose monitoring. A quantitative, quasi-experimental study was conducted in a laboratory at the University of New Hampshire. 96 volunteers were randomly assigned to one of three groups. Each group underwent a pair of capillary blood glucose tests …

Overview Of Glp-1ra Medications, Thomas Cordaro, Sumaiya Difaa, Amel Basil

Transformative Medicine

GLP-1 is an incretin hormone that is naturally produced in the body that regulates blood glucose and appetite. The first GLP-1RA that was FDA approved, exenatide, in 2005, originated from the Gila monster and beaded lizard, via the discovery of the exendin-4 peptide. GLP-1RAs function by mimicking endogenous GLP-1 incretin hormone, leading to an increase in glucose-dependent insulin release from beta-cells of the pancreas, decrease in glucagon release, delayed gastric emptying, and satiety. Due to the benefits seen from initiating GLP-1RAs in the market, it sparked interest in numerous studies which proved that certain GLP-1RAs can provide cardiorenal protection. The …

Glynac (Glycine And N-Acetylcysteine) Supplementation In Mice Increases Length Of Life By Correcting Glutathione Deficiency, Oxidative Stress, Mitochondrial Dysfunction, Abnormalities In Mitophagy And Nutrient Sensing, And Genomic Damage

Faculty and Staff Publications

Determinants of length of life are not well understood, and therefore increasing lifespan is a challenge. Cardinal theories of aging suggest that oxidative stress (OxS) and mitochondrial dysfunction contribute to the aging process, but it is unclear if they could also impact lifespan. Glutathione (GSH), the most abundant intracellular antioxidant, protects cells from OxS and is necessary for maintaining mitochondrial health, but GSH levels decline with aging. Based on published human studies where we found that supplementing glycine and N-acetylcysteine (GlyNAC) improved/corrected GSH deficiency, OxS and mitochondrial dysfunction, we hypothesized that GlyNAC supplementation could increase longevity. We tested our hypothesis …

Association Between Vitamin D Status And Cortisol Concentration Among Pregnant Women, Kenneth Addae

Open Access Master's Theses

Objective: Vitamin D deficiency (VDD) and high circulating cortisol during pregnancy have each been linked to adverse maternal and child outcomes such as preterm birth. However, limited research has explored the association between vitamin D status and cortisol concentration during pregnancy. Our objective for this study was to determine the association between vitamin D status and cortisol concentration among pregnant women.

Methods: The Prenatal Health and Nutrition (PHAN) study was a pilot cross-sectional study of 30 healthy pregnant women conducted in targeted areas in Rhode Island. Data was collected on sociodemographic characteristics, substance use, perceived stress scale, household food security, …

Alcohol And The Endocrine System: A Critical Review Of Disruptions, Potential Mechanisms, And Health Implications

School of Graduate Studies Faculty Publications

The endocrine system coordinates and integrates cellular activity throughout the body by regulating cellular and organ function and maintaining homeostasis. Homeostasis, the dynamic maintenance of internal balance despite changing external or internal conditions, is essential for proper cellular function. The endocrine system achieves this through a complex regulatory network of hormone-mediated signaling among multiple endocrine organs, relying on precisely regulated synthesis and release of hormones and specific hormone-receptor interactions. Endocrine-mediated actions coordinate critical physiological processes, including growth, metabolism, reproduction, stress adaptation, and circadian rhythms throughout the lifespan. Endocrine glands—such as the hypothalamus, pituitary, thyroid, parathyroid glands, pancreas, adrenal glands, and …
