Integrated Evidence from VigiBase and Clinical Trials: A Comprehensive Pharmacovigilance Analysis of Seven Glucagon-Like Peptide 1 Receptor Agonists (GLP-1 RAs).

Diabetes Ther

Jiaxun Li, Jizhou Liang, Wei Zhang +2 more

Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are key therapies for type 2 diabetes and obesity, regulating blood glucose by mimicking endogenous GLP-1. Despite efficacy, GLP-1 RAs are associated with adverse reactions across multiple organ systems. To address the gap in class-wide comparative safety analyses beyond previous studies limited to single drugs or organ systems, this study systematically evaluated adverse events for all approved GLP-1 RAs to identify hidden risks and support clinical decision-making.

Harnessing Herbal Power: A Systematic Review of Phytopharmaceuticals in Type 2 Diabetes Management.

J Am Nutr Assoc

Kamalika Chattopadhyay, Pankaj Kumar, Ravishankar Ram Mani +3 more

The Type 2 diabetes mellitus (T2DM) is one of the key health crises facing the world, with the prevalence expected to surpass 783 million adults by the year 2045. It causes premature disability, death and enormous social and economic costs. It is believed that the number of diabetes mellitus (DM) may increase to 592 million in 2035. Although there are conventional therapies, they are very expensive and limited. Despite the fact drugs that are produced synthetically are effective in controlling the disease, there are some side effects that are related with their long-term use. Consequently, the role of the traditional medicine such as plant extracts and pharmacological compounds derived out of plants is becoming very popular. The purpose of this review is to bring together the existing research on the effectiveness of herbal medicine in treating T2DM and especially phytochemicals based on in vitro, in vivo and clinical studies.

Quantitative β-Cell Mass Imaging Redefines Disease Staging and Glycemic Control in Type 1 Diabetes.

Diabetes

Kentaro Sakaki, Takaaki Murakami, Hayao Yoshida +7 more

Noninvasive measurement of pancreatic β-cell mass remains an important unmet need in type 1 diabetes because conventional surrogate markers, such as C-peptide, often lack sensitivity in advanced disease. This study evaluated the glucagon-like peptide 1 receptor-targeted positron emission tomography tracer, 18F-labeled exendin-4-based probe conjugated with polyethylene glycol, [18F]FB(ePEG12)12-exendin-4 (18F-exendin-4), to determine its ability to visualize pancreatic β-cell mass. Positron emission tomography/computed tomography performed at 60 and 120 min after tracer injection in individuals with type 1 diabetes was compared with data from healthy control participants. No serious adverse events occurred. Pancreatic uptake was consistently lower in individuals with type 1 diabetes and showed clear separation between individuals with insulin-dependent diabetes and healthy control participants at 120 min. Pancreatic uptake at 120 min correlated with fasting C-peptide index and inversely with hemoglobin A1c and daily insulin dose per body weight. These findings support [18F]FB(ePEG12)12-exendin-4 positron emission tomography/computed tomography as a noninvasive approach for assessing β-cell mass and disease status.

Evaluating sotatercept in the treatment of pulmonary arterial hypertension.

Future Cardiol

William Salibe-Filho, Nathalia Zorze Rossetto, Luiza Sarmento Tatagiba +5 more

Pulmonary arterial hypertension (PAH) is a progressive disease characterized by pulmonary vascular remodeling, right ventricular overload, and premature death. Despite advances achieved through endothelin receptor antagonists, phosphodiesterase type 5 inhibitors, and prostacyclin analogs, these agents primarily act as vasodilators and do not reverse underlying vascular pathology. Sotatercept, a first-in-class activin signaling modulator, restores the balance between pro- and antiproliferative signaling within the pulmonary vasculature via the TGF-β/activin-BMPR2 pathway, offering a novel disease-modifying mechanism. Following encouraging preclinical data, a series of clinical trials, PULSAR, SPECTRA, STELLAR, ZENITH, and HYPERION, demonstrated consistent efficacy across diverse PAH populations. Sotatercept significantly reduced pulmonary vascular resistance, improved exercise capacity, and decreased morbidity and mortality, including in patients receiving maximal background therapy. Across studies, adverse events were generally mild to moderate, with epistaxis, telangiectasia, and increased hemoglobin being the most common treatment-related events. Collectively, these findings establish sotatercept as a major advance in PAH therapy, marking a transition from purely vasodilatory approaches toward targeted modulation of vascular remodeling. By improving pulmonary hemodynamics and right ventricular function, sotatercept represents a new therapeutic option for improving clinical outcomes across different stages of PAH.

Metabolic advances in 2025: from clinical breakthroughs to molecular reprogramming.

Metabol Open

Maria Dalamaga, Junli Liu

The year 2025 represented a turning point in metabolic research, marked by advances that combined unprecedented clinical efficacy with deep mechanistic insight. Landmark obesity trials redefined therapeutic expectations, with head-to-head and combination studies showing that the depth and distribution of weight loss are critical determinants of metabolic benefit across obesity and type 2 diabetes. In parallel, gene-editing studies crossed a translational threshold, showing that durable modification of metabolic pathways in humans is feasible, from bespoke correction of inborn errors to population-scale lipid lowering. Mechanistic investigations challenged long-standing assumptions about metabolic regulation. Experimental work revealed that mitochondrial electron transport functions as a dynamic redox regulator rather than a passive energy conduit, linking coenzyme Q imbalance and reverse electron transport to hepatic steatosis and metabolic dysfunction. Other studies reframed nutrient exposure and endogenous metabolites, demonstrating that non-nutritive sweeteners and cyanide exert context-dependent metabolic effects through regulated endocrine and redox pathways. At the systems level, multi-omics analyses defined reproducible microbiome-metabolome signatures associated with impaired glucose regulation, while artificial intelligence and continuous glucose monitoring exposed dynamic glycemic phenotypes invisible to conventional biomarkers. Precision-nutrition studies further showed that selective manipulation of sulfur amino acid availability can program thermogenic and metabolic responses. Collectively, these studies illustrate how metabolism in 2025 was approached as a modifiable, programmable system, shaped by clinical intervention, molecular control, and data-driven phenotyping, and point toward an era of increasingly precise and integrated metabolic medicine.

Aging disrupts the temporal organization of slow oscillations beyond density reduction.

PNAS Nexus

Lucila Capurro, Michael Radloff, María C González +4 more

Macroscopic and rhythmic brain oscillations have recently been shown to play a crucial role in glymphatic function by promoting cerebrospinal fluid flow and facilitating the clearance of metabolic waste. While age-related reductions in the number and amplitude of slow oscillations (SOs; 0.5-1 Hz) are well documented and associated with impaired clearance, little is known about how aging affects the temporal structure of these oscillations. Here, we propose that the rhythmic dynamics with which SOs occur represent a critical, yet overlooked, feature supporting glymphatic function. We introduce a novel classification of SOs based on their temporal organization, distinguishing isolated SOs from trains of consecutive oscillations according to inter-SO intervals. Using overnight electroencephalographic recordings from 57 young and 51 elderly adults across three independent datasets, we compared the proportions of isolated and consecutive SOs as well as the distribution of train lengths. Elderly adults displayed a significantly higher proportion of isolated SOs and shorter oscillatory trains than young adults, even after controlling for SO density and stage composition. Temporal shuffling procedures and analyses of density-matched epochs further supported that these differences cannot be attributed solely to density but instead reflect a genuine age-related loss of rhythmicity. These findings reveal that natural aging not only reduces the amount and amplitude of SOs but also disrupts their temporal regularity. This alteration may weaken the sustained ionic currents that drive cerebrospinal fluid flow, compromise the efficiency of metabolic clearance during sleep, and thereby contribute to increased vulnerability to age-related neurodegenerative processes.
