Association Between Plasma LRG1 and Lower Cognitive Function in Asians With Type 2 Diabetes Mellitus.

Context: Leucine-rich α-2-glycoprotein 1 (LRG1) has been implicated in the pathogenesis of diabetic complications, but its association with cognitive function remains unclear.

Objective: Our primary objective is to investigate the longitudinal association between LRG1 and cognitive function in patients with type 2 diabetes mellitus (T2DM). Secondarily, we determine the causal relationship using Mendelian randomization (MR) and the role of arterial stiffness as a potential mediator.

Short-term Weight Trajectory of Severely Obese Individuals With and Without Pathogenic Satiety-Regulation Melanocortin 3/4 Receptor (MC3/4R) Mutations From a Multi-ethnic Asian Large Bariatric Surgery Program.

The melanocortin (3 or 4) receptor (MC3/4R) is involved in regulating satiety and body weight. Therefore, pathogenic mutation in MC3/4R is associated with severe obesity, for which bariatric surgery is one of the treatment options. However, there is limited data on whether individuals with MC3/4R mutation will have differential weight response to surgery, especially among the Asian populations-the epi-center of the evolving global obesity epidemic.

Long-Term Observation of a Man With Severe Obesity and Undiagnosed Monogenic Diabetes Serendipitously Treated With Metabolic Surgery.

A 43-year-old man, with severe obesity (43 kg/m) and diabetes (presumed as type 2 diabetes [T2D]), underwent vertical sleeve gastrectomy in 2009 and Roux-en-Y gastric bypass in 2013. Recently, whole exome sequencing (conducted to search for monogenic obesity) serendipitously revealed that the individual harbored a heterozygous glucokinase () variant p.(Arg422Leu) that was bioinformatically strongly predicted to be likely pathogenic.
