Pretorius, Thomas R. Sullivan, Summer V.M. Walker, Johan Garssen, Jeffrey A. Keelan, Desiree Silva, Susan L. Prescott, Debra J. Palmer

Research outputs 2022 to 2026

Background: Prebiotic dietary supplementation has been shown to improve glucose homeostasis in type 2 diabetes patients. The aim of this analysis was to determine whether pre-pregnancy body mass index (BMI) modifies the effect of prebiotic supplementation from mid-pregnancy on reducing the risk of gestational diabetes mellitus (GDM). Methods: In a double-blinded, randomised controlled trial, pregnant women < 21 gestational weeks were randomly assigned (1:1) to consume daily prebiotics (14.2 g galacto-oligosaccharides and fructo-oligosaccharides) or placebo (8.7 g maltodextrin) powder. An effect modification analysis was performed to assess the heterogeneity of the effect of prebiotic supplementation in relation to pre-pregnancy BMI on GDM diagnosis. Results: Between June 2016 and November 2021, 329 women were assigned to the prebiotic group (50.4%), and 323 (49.5%) were assigned to the placebo group. Overall, 288 of 652 women (44.2%) were classified as overweight/obese prior to pregnancy (BMI ≥ 25 kg/m²). The distribution was balanced, with 146/329 (44.4%) randomised to the prebiotics group and 142/323 (44.0%) in the placebo group. Pre-pregnancy BMI modified the effect of prebiotic supplementation, with the intervention reducing GDM rates in women with a BMI ≥ 25 kg/m^{2 …}

Danon, Delwyn Catley, Richard A. Washburn, Amy Bodde, Francisco J. Diaz, Brian C. Helsel, Anna M. Rice, Joseph R. Sherman, Madison Koester, Walker S. Mckinney Ph.D., Joseph E. Donnelly

Manuscripts, Articles, Book Chapters and Other Papers

Young adults with intellectual disability (ID) are an underserved population with a high prevalence of obesity, obesity-related health conditions, and reduced ability to complete instrumental and basic activities of daily living (I/ADLs). After leaving the structured environment of public school, many young adults with ID spend more time at home or in day programs, begin living more independently, or enter the workforce. These transitions may increase reliance on fast or processed foods and reduce opportunities for physical activity, contributing to accelerated weight gain. Previous research has demonstrated clinically meaningful short- and long-term weight loss (18-24 months) in adults with mild-to-moderate …

Myeloid Mmp14 Couples Extracellular Proteolysis To Inflammatory And Metabolic Remodeling During Obesity, Long J Shao, Fathima Elizondo, Feng Gao, Elizabeth L Lieu, Bharati Reddi, Maryam Elizondo, Iqbal Mahmud, Kristin Eckel-Mahan, Philipp E Scherer, Xin Ge, Huaizhu Wu, Sean Hartig, Kai Sun

The Brown Foundation: Institute of Molecular Medicine

Macrophages orchestrate tissue remodeling, inflammation, and metabolic dysfunction in obesity, but the role of macrophage-intrinsic extracellular proteolysis in immunometabolic regulation remains unclear. Matrix metalloproteinase-14 (MMP14), a membrane-bound protease, is strongly induced during monocyte-to-macrophage differentiation and further elevated in adipose tissue macrophages from high-fat diet (HFD)-fed mice. Pharmacological inhibition or myeloid-specific deletion of Mmp14 impaired macrophage differentiation, proliferation, migration, phagocytosis, and inflammatory activation in response to obesity-associated adipose tissue signals. Mechanistically, MMP14 promoted inflammatory programming by increasing endotrophin generation and enhancing TLR4-NFκB signaling. MMP14 also reprogrammed macrophage lipid metabolism by suppressing lipolysis and promoting lipid accumulation, altering metabolic communication with neighboring …

The Effect Of Hunger On The Likelihood Of Glucose Excursions In Adults With Overweight Or Obesity: Continuous Glucose Monitoring And Ecological Momentary Assessment Observational Study, Byunggul Lim, Phrashiah Githinji, Yue Liao, Jacob Szeszulski, Alexandra L Macmillan Uribe, Rebecca A Seguin-Fowler, Jane Anderson, Chad D Rethorst

Faculty, Staff and Students Publications

Background: Maintaining stable glucose levels is important for metabolic health. Glucose excursions (GEs), which are marked increases in glucose following food intake, have been associated with a higher risk for cardiovascular disease and metabolic dysfunction. Individuals with overweight or obesity who do not have diabetes may still show impaired glucose regulation, as reflected in increased glucose variability. Hunger, as a real-time physiological cue, may be associated with subsequent glucose changes and represents a potential target for just-in-time adaptive interventions.

Objective: This study aimed to investigate the temporal relationship between self-reported hunger and subsequent glucose dynamics, including the likelihood of GE …

Faculty, Staff and Students Publications

Objective: Obesity is a chronic disease linked to high mortality and morbidity after cardiac procedures, but its relationship to outcomes after total aortic arch replacement (TAR) remains unclear. We examined TAR data to determine whether obesity is associated with greater perioperative risk.

Methods: Among 787 TARs performed from 1990 to 2023, we excluded patients who lacked body mass index (BMI) data, had nonelective or nonstandard repairs, or were underweight (BMI < 18.5 kg/m2). The remaining 521 patients did not have obesity (18.5 ≤BMI < 30; n = 389) or did (BMI ≥30; n = 132). Patients with obesity were class 1 (30 ≤ BMI < 35), class 2 (35 ≤ BMI < 40), or class 3 (BMI ≥40). We compared preoperative and perioperative variables for BMI ≥30 (obesity) versus BMI < 30. Adverse events were operative mortality, persistent stroke, spinal cord deficit, and renal failure. We performed multivariable logistic regression and Kaplan-Meier survival analysis.

Results: Patients with obesity had greater rates of obstructive sleep apnea, transient spinal cord deficit, and acute renal dysfunction than patients with normal weight. During repair, the use of antegrade …

The Brown Foundation: Institute of Molecular Medicine

Stress and diet are known to synergistically promote risks of obesity but the underlying neural basis remains elusive. Corticotropin-releasing hormone neurons in the paraventricular hypothalamus (PVHCRH) are stress responsive and release both CRH and glutamate. Here we generated a mouse model with gain or loss of release in CRH or glutamate from PVHCRH neurons. While these models showed no changes in body weight when fed chow, they exhibited contrasting effects when fed high-fat high-caloric diets (HFD). Whereas disrupting glutamate release from PVHCRH neurons led to diet-induced obesity (DIO), that of CRH caused no impact. Conversely, augmented CRH release led to …

Glp-1 Receptor Agonists And Disordered Eating: Clinical Indicators And Patient Narratives, Samantha E. Schulz

Masters Theses

Introduction: The use of the medication, GLP-1 receptor agonist (GLP-1 RA), for weight loss has increased exponentially in the United States over the past decade. The continuing rise in demand for the use of GLP-1 RAs for weight loss justifies the need to better understand the physical and psychological effects that can occur with significant weight loss. By combining a standardized screening tool for eating disorder (ED) risk with narratives from patients undergoing GLP-1 RA treatment for weight loss, this study examines associations between GLP-1 RA use patterns and risk of ED and explores patient experiences, including the role of …

Impact Of Early Term Induction Of Labor On Cesarean Delivery And Impact Of Early Term Induction Of Labor On Cesarean Delivery And Maternal-Fetal Outcomes In Patients With Obesity: A Maternal-Fetal Outcomes In Patients With Obesity, Priya Patel, Nathanael Hoskins

Rowan-Virtua Research Day

Introduction: Obesity (body mass index [BMI] ≥30 kg/m²) in pregnancy is associated with increased risks, including gestational diabetes, hypertensive disorders, and higher cesarean delivery (CD) rates. Evidence supporting early-term (37 0/7–38 6/7 weeks) induction of labor (IOL) to improve outcomes remains limited. This study evaluated whether IOL in patients with obesity is associated with decreased CD rates.

Methods: This retrospective cohort study included pregnancies undergoing IOL between 37 0/7 and 41 6/7 weeks from 2018–2023 at a single institution. Exclusion criteria included spontaneous labor, prior CD, multiple gestations, fetal anomalies, non-vertex presentation, and pre-labor rupture of membranes. Primary exposures were …

Obesity Paradox In Post-Cholecystectomy Outcomes: A Bmi Class–Based Trinetx Analysis At 6 Months And 1 Year, Jashanveer S. Johal, Mahmoud Al-Bataineh, Bianca Patel, Archana Salek, Om Patel, Jason Hyman, Yecheskel Schneider, Abdallah Hussein

Rowan-Virtua Research Day

Background: Obesity is traditionally associated with higher perioperative risk, yet observational data suggest an "obesity paradox" in which obese patients experience comparable or better outcomes than non-obese peers. We evaluated the impact of obesity (BMI ≥30 kg/m²) and obesity class on post-cholecystectomy outcomes.

Methods: A retrospective cohort study was conducted using the TriNetX global federated network. Adults undergoing cholecystectomy with BMI < 30 kg/m² were propensity score–matched 1:1 to those with BMI ≥30 kg/m², yielding 81,048 patients per group. Primary outcomes included choledocholithiasis, procedural complications, need for ERCP, and ED/inpatient utilization; secondary outcomes included mortality, respiratory and cardiovascular complications, and upgrade of care. Outcomes were assessed at 6 months and 1 year. A prespecified subgroup analysis compared BMI 30–39 versus BMI ≥40 kg/m² (40,238 per cohort).

Results: Obese patients consistently demonstrated lower rates of major outcomes at both timepoints. At 1 year, BMI < 30 had higher risks of choledocholithiasis (9.1% vs. 8.0%; RR 1.13), procedural complications (3.8% vs. 3.1%; RR 1.22), ERCP (5.4% vs. 4.6%; RR 1.19), and ED/inpatient visits (30.3% vs. 28.8%; RR 1.05; all p< 0.001). Mortality was also higher in non-obese patients at 1 year (1.4% vs. 1.2%; RR 1.20). Within the obese subgroup, BMI 30–39 and BMI ≥40 had broadly similar complication and utilization rates, though 1-year mortality was lowest in class I–II obesity (0.8% vs. 1.0%; RR 0.85).

Conclusions: Obesity was associated with better post-cholecystectomy outcomes compared with BMI < 30 kg/m², supporting an obesity paradox in biliary surgery. BMI alone should not deter cholecystectomy, and perioperative risk stratification should incorporate factors beyond weight class.
