Glucagon-like peptide-1 effect on β-cell function varies according to diabetes remission status after Roux-en-Y gastric bypass.

Aims: The contribution of endogenous glucagon-like peptide (GLP)-1 to β-cell function after Roux-en-Y gastric bypass surgery (RYGB) is well established in normoglycaemic individuals, but not in those with postoperative hyperglycaemia. We, therefore, studied the effect of GLP-1 on β-cell function in individuals with varying degrees of type 2 diabetes mellitus (T2D) control after RYGB.

Materials And Methods: Glucose, insulin secretion rates, β-cell glucose sensitivity and glucagon were measured during an oral glucose tolerance test before (saline only) and at 3, 12 and 24 months after RYGB with and without infusion of the GLP-1 receptor blocker exendin (EX9).

Temporal Eating Patterns and Eating Windows among Adults with Overweight or Obesity.

We aim to describe temporal eating patterns in a population of adults with overweight or obesity. In this cross-sectional analysis, data were combined from two separate pilot studies during which participants entered the timing of all eating occasions (>0 kcals) for 10-14 days. Data were aggregated to determine total eating occasions, local time of the first and last eating occasions, eating window, eating midpoint, and within-person variability of eating patterns.

Role of the Gut in the Temporal Changes of β-Cell Function After Gastric Bypass in Individuals With and Without Diabetes Remission.

Objective: The role of the gut in diabetes remission after Roux-en-Y gastric bypass (RYGB) is incompletely understood. We assessed the temporal change in insulin secretory capacity after RYGB, using oral and intravenous (IV) glucose, in individuals with type 2 diabetes.

Research Design And Methods: Longitudinal, prospective measures of β-cell function were assessed after oral glucose intake and graded glucose infusion in individuals with severe obesity and diabetes studied at 0, 3 (n = 29), 12 (n = 24), and 24 (n = 20) months after RYGB.

Preintervention Clinical Determinants and Measured β-Cell Function As Predictors of Type 2 Diabetes Remission After Roux-en-Y Gastric Bypass Surgery.

Background: Bariatric surgery results in improved glycemic control in individuals with type 2 diabetes. Single and clusters of clinical determinants have been identified as presurgery predictors of postsurgery diabetes remission. Our goal was to assess whether the addition of measured preoperative β-cell function would improve established clinical models of prediction of diabetes remission.

A Smartphone Intervention to Promote Time Restricted Eating Reduces Body Weight and Blood Pressure in Adults with Overweight and Obesity: A Pilot Study.

The goal of this study was to test the feasibility of time restricted eating (TRE) in adults with overweight and obesity. Participants ( = 50) logged all eating occasions (>0 kcal) for a 2-week run-in period using a smartphone application. Participants with eating duration ≥14 h enrolled in an open label, non-randomized, prospective 90-day TRE intervention, with a self-selected reduced eating window of 10 h.

Anthropometrics by Three-Dimensional Photonic Scanner in Patients with Obesity Before and After Bariatric Surgery.

Background: We studied body composition by three-dimensional photonic scanning (3DPS) and metabolic biomarkers in a large ethnically diverse cohort of individuals with severe obesity before and after weight loss by Roux-en-Y gastric bypass (RYGB) or adjustable gastric banding (AGB) surgery.

Materials And Methods: Male and female participants (n = 95) underwent 3DPS testing in the weeks preceding bariatric surgery (baseline), and 1 year after either RYGB (n = 34) or AGB (n = 9).

Results: Principal component analysis showed that A1C and HDL cholesterol clustered with waist-to-hip ratio (WHR).

Leveraging phytochemicals: the plant phylogeny predicts sources of novel antibacterial compounds.

Aim: The goal of this study was to use phylogenetic evidence to determine plant families with high representation of antibacterial activity and identify potential sources to focus on for antibacterial drug discovery.

Materials & Methods: We reconstructed the molecular phylogeny of plant taxa with antibacterial activity and mapped antibacterial mechanisms of action on the phylogeny.

Results: The phylogeny highlighted seven plant families (Combretaceae, Cupressaceae, Fabaceae, Lamiaceae, Lauraceae, Myrtaceae and Zingiberaceae) with disproportionately represented antibacterial activity.

Primary adenocarcinoma of cutaneous vesicostomy 40 years later: a rare case.

We present a case of adenocarcinoma developing at the vesicocutaneous edge of a vesicostomy, 40 years after it was created, in a patient who underwent cadaveric kidney transplant. Although transitional and squamous cell carcinoma of a vesicostomy have been reported, to our knowledge, the presence of adenocarcinoma at the vesicostomy edge has not been reported previously.
