Changes in energy homeostasis, gut peptides, and gut microbiota in Emiratis with obesity after bariatric surgery.

Background: Obesity is a growing health concern worldwide, including United Arab Emirates. Bariatric surgery is an effective treatment option, with to date unclear weight loss mechanisms. In this prospective study, we explored post-bariatric surgery changes in energy homeostasis, gut peptides, hormones, and gut microbiota.

Gut microbiota composition of lean and obese Lebanese individuals.

An altered gut microbiota has been shown to contribute to the development of metabolic diseases such as obesity. In this study gut microbiota profile of 30 obese and 23 lean Lebanese individuals was performed via DNA isolation and sequencing of the V3-V4 region of the 16S rRNA of faecal samples. The abundance of the phylum Verrucomicrobiota was higher in lean subjects and there was no significant difference in the Bacillota/ Bacteroidota ratio between the obese and lean groups.

The Association of Peptide Hormones with Glycemia, Dyslipidemia, and Obesity in Lebanese Individuals.

Peptide-hormones, including pancreatic peptide-YY(PYY), glucagon-like peptide-1 (GLP-1), cholecystokinin (CCK), insulin, and leptin function as satiety signals, while ghrelin promotes hunger. These hormones are also involved in glucose homeostasis and body-weight regulation. The aim of this cross-sectional analysis was to examine the association of these peptide-hormones with obesity-markers, insulin-resistance, and dyslipidemia (total-cholesterol (TC), low-density-lipoprotein-cholesterol (LDL-C), high-density-lipoprotein-cholesterol (HDL-C), triglyceride (TG)).

Lean Body Mass and Self-Perceived Body Image among Youth in the United Arab Emirates.

Background And Aim: Lean body mass may be a promising tool to screen body image disorders. This study aim was to explore the relationships between fat free mass index (FFM-I) on self-perceived body image and shape among university students in the United Arab Emirates.

Methods: Cross-sectional study, using questionnaires to evaluate demographics, body figure, shape and image dissatisfaction; in addition to anthropometrics like BMI and FFM-I.
