Prevention of childhood-onset type 1 diabetes has become more urgent with its marked increased incidence in recent decades in the modern world. Temporally associated with the rising incidence of type 1 diabetes, as well as other autoimmune and allergic diseases in childhood in modern times, is the disappearance of Bifidobacterium and specifically Bifidobacterium longum subsp. infantis (B. infantis) predominance in the intestinal microbiota of breastfed, vaginally-delivered infants. B. infantis efficiently metabolizes human milk oligosaccharides (HMOs) without cross-feeding free sugar monomers to other commensals or pathogens and thereby dominates the intestinal microbiota of breastfed infants. Increased levels of short-chain fatty acids (SCFA), which stimulate both immunoregulation and healthy intestinal and pancreatic β-cell function, are generated by B. infantis. Based on recent observations of the intestinal microbiota in early life in young children who develop type 1 diabetes and demonstration of the robust preventive effects of SCFA in animal models of autoimmune diabetes, we hypothesize that restoring a B. infantis-dominant microbiota early in infancy will prevent islet autoimmunity and childhood-onset type 1 diabetes.

Regular human insulins versus rapid-acting insulin analogues in children and adolescents with type 1 diabetes: a protocol for a systematic review with meta-analysis and Trial Sequential Analysis.
Syst Rev

Background: Type 1 diabetes is a serious, chronic disorder with an increasing incidence among children and adolescents. Glycemic control in individuals with type 1 diabetes is better managed through a basal-bolus regimen with either regular human or rapid-acting insulin analogues administered as a bolus at mealtimes. Rapid-acting insulin analogues have been hypothesized to cause optimal glycemic control and less risk of hypoglycemic episodes compared to regular human insulins.

Department of Endocrine and Metabolic Diseases, Shanghai Institute of Endocrine and Metabolic Diseases, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.
Aim: To explore the holistic impact of socioeconomic and mental health inequalities on the global burden of type 2 diabetes.
Materials And Methods: This cross-sectional study used data on the incidence, disability-adjusted life years (DALYs), and mortality of type 2 diabetes as well as DALYs attributable to risk factors during 1990-2021 from the Global Burden of Disease Study 2021. Average annual percent change (AAPC) was applied to assess the temporal trends from 1990 to 2021.
Greater improvement in insulin sensitivity per unit weight loss associated with tirzepatide versus semaglutide: An exploratory analysis.
Diabetes Obes Metab
January 2025
Eli Lilly and Company, Indianapolis, Indiana, USA.
Aims: To explore the relationship between weight loss and insulin sensitivity in response to tirzepatide or semaglutide.
Materials And Methods: We conducted a post hoc exploratory analysis of a 28-week, double-blind, randomized trial in people with type 2 diabetes treated with metformin, randomized to tirzepatide 15 mg, semaglutide 1 mg or placebo. We evaluated the relationship between change in body weight and change in insulin sensitivity determined from hyperinsulinemic euglycemic clamp (M value), or from mixed-meal tolerance testing (Matsuda index).
Treatment outcomes with oral anti-hyperglycaemic therapies in people with diabetes secondary to a pancreatic condition (type 3c diabetes): A population-based cohort study.
Diabetes Obes Metab
January 2025
Department of Clinical and Biomedical Sciences, University of Exeter Medical School, Exeter, UK.
Aims: To assess outcomes of oral anti-hyperglycaemic therapies in people with diabetes secondary to a pancreatic condition (type 3c), where specific treatment guidance is limited.
Materials And Methods: Using hospital-linked UK primary care records (Clinical Practice Research Datalink; 2004-2020), we identified 7084 people with a pancreatic condition (acute pancreatitis, chronic pancreatitis, pancreatic cancer and haemochromatosis) preceding diabetes diagnosis (type 3c cohort), initiating oral glucose-lowering therapy (metformin, sulphonylureas, SGLT2-inhibitors, DPP4-inhibitors or thiazolidinediones), and without concurrent insulin treatment. We stratified by pancreatic exocrine insufficiency [PEI] (n = 5917 without PEI, 1167 with PEI) and matched to 97 227 type 2 diabetes (T2D) controls.
Association of TCF7L2 genetic variants rs12255372 and rs7903146 with the polycystic ovary syndrome risk: systemic review and meta-analysis.

Background: A significant overlap in the pathophysiological features of polycystic ovary syndrome (PCOS) and type 2 diabetes mellitus (T2DM) has been reported; and insulin resistance is considered a central driver in both. The expression and hepatic clearance of insulin and subsequent glucose homeostasis are mediated by TCF7L2 via Wnt signaling. Studies have persistently associated TCF7L2 genetic variations with T2DM, however, its results on PCOS are sparse and inconsistent.
