To establish whether obesity involves activation of endogenous ciliary neurotrophic factor (CNTF) signalling, we evaluated its plasma levels in patients with obesity and correlated its values with the major clinical and haematological indices of obesity, insulin resistance and systemic inflammation. This study involved 118 subjects: 39 healthy controls (19 men), 39 subjects with obesity (19 men) and 40 subjects with obesity and diabetes (20 men). Plasma CNTF and CNTF receptor α (CNTFRα) were measured using commercial ELISA kits. The results showed that plasma CNTF was significantly higher in males and females with obesity with and without diabetes than in healthy subjects. Women consistently exhibited higher levels of circulating CNTF. In both genders, CNTF levels correlated significantly and positively with obesity (BMI, WHR, leptin), diabetes (fasting insulin, HOMA index and HbA1c) and inflammation (IL-6 and hsCRP) indices. Circulating CNTFRα and the CNTF/CNTFRα molar ratio tended to be higher in the patient groups than in controls. In conclusion, endogenous CNTF signalling is activated in human obesity and may help counteract some adverse effects of obesity. Studies involving a higher number of selected patients may reveal circulating CNTF and/or CNTFRα as potential novel diagnostic and/or prognostic markers of obesity, diabetes and associated diseases.

Background: Age-related macular degeneration (AMD) decrease vision and presents considerable challenges for both public health and clinical management strategies. Obesity is usually implicated with increased AMD, and body mass index (BMI) does not reflect body fat distribution. An array of studies has indicated a robust relationship between body fat distribution and obesity.

Background: Metabolic and Bariatric Surgery (MBS) is often difficult to access for the adolescent population. Eligibility criteria have been recently updated to attempt to remove barriers in accessing this care.
Objectives: Analyze recent trends in adolescent MBS in the context of these recent policy changes.

Gene circuits, which are genetically engineered systems designed to regulate gene expression, are emerging as powerful tools in disease theranostics, especially in mammalian cells. This review explores the latest advances in the design and application of gene circuits for detecting and treating various diseases. Synthetic gene circuits, inspired by electronic systems, offer precise control over therapeutic gene activity, allowing for real-time, user-defined responses to pathological signals.

Background: Flavonoids are naturally occurring dietary phytochemicals with significant antioxidant effects aside from several health benefits. People often consume them in combination with other food components. Compiling data establishes a link between bioactive flavonoids and prevention of several diseases in animal models, including cardiovascular diseases, diabetes, gut dysbiosis, and metabolic dysfunction-associated steatotic liver disease (MASLD).

Background: Bariatric surgery is the most effective intervention for severe pediatric obesity, but a subset of youth experience suboptimal weight loss and/or recurrent weight gain. Early re-initiation of obesity pharmacotherapy postoperatively may improve outcomes, though this has not been evaluated in pediatric populations.
Methods: A retrospective cohort study at a tertiary care children's hospital evaluated the safety and efficacy of reintroducing obesity pharmacotherapy within six weeks after laparoscopic sleeve gastrectomy (LSG).
