Glucagon, a hormone secreted from the alpha cell of the endocrine pancreas, is a major counterpart to insulin. After released into blood, glucagon will combine with its receptor in targeting tissues and form a compound, which then activates its signaling pathway, produces cAMP, promotes gluconeogenesis and glycogenolysis and inventually increases blood glucose. Researches recently display that it will be an important addition to treatment method by inhibiting synthesis and secretion of glucagon, neutralizing circulating glucagon, using glucagon receptor antagonists and prohibiting gene expression of glucagon receptor.

Importance: Obesity, a chronic disease with escalating global prevalence, poses considerable health risks. Glucagon-like peptide 1 receptor agonists (GLP-1RAs), including liraglutide, semaglutide, and tirzepatide, have demonstrated efficacy for weight loss in clinical trials. The paradigm shift in the approach to obesity management drugs (OMDs) may offer an opportunity to examine online search activity and prescription trends.

Objective: Obesity is a major risk factor for osteoarthritis (OA). Adipose tissues may be linked to OA development through secretion of potential proinflammatory cytokines including neutrophil gelatinase-associated lipocalin (NGAL). Our objective was to assess changes in serum NGAL after a low-calorie diet (LCD) and subsequent glucagon-like peptide 1 receptor agonist (GLP-1 RA) treatment.

This article comments on the work by Soresi and Giannitrapani. The authors have stated that one of the most novel and promising treatments for metabolic dysfunction-associated steatotic liver disease (MASLD) is the use of glucagon-like peptide 1 receptor agonists, especially when used in combination therapy. However, despite their notable efficacy, these drugs were not initially designed to target MASLD directly.

Objectives: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are now widely used for treating type 2 diabetes mellitus (T2DM) and obesity. We examined their association with acetonemic vomiting, especially when given to patients with low body weight, in hopes of achieving early recognition of this complication which is potentially life-threatening if not dealt with appropriately.
Methods: Cases identified incidentally are described and discussed referring to prior reports.

The hypothalamus is a master regulator of energy balance in the body. First-order hypothalamic neurons localized in the arcuate nucleus sense systemic signals that indicate the energy stores in the body. Through distinct projections, arcuate nucleus neurons communicate with second-order neurons, which are mostly localized in the paraventricular nucleus and in the lateral hypothalamus.
