Circulating short-chain and branched short-chain fatty acids and the risk of incident type 2 diabetes: findings from the 4C study.

Previous studies suggested that fecal short-chain fatty acids (SCFAs) and branched short-chain fatty acids (BCFAs) are associated with glucose regulation. However, the potential relationship between circulating SCFAs and BCFAs with incident diabetes risk in both men and women remains unidentified in prospective cohort studies. In this study, we examined a panel of nine serum SCFAs and BCFAs in 3414 subjects with incident diabetes, and matched normoglycemic controls from the China Cardiometabolic Disease and Cancer Cohort study.

Gut Microbiota-Butyrate-PPARγ Axis Modulates Adipose Regulatory T Cell Population.

Gut microbiota is essential for the function of peripherally-induced regulatory T (pTreg) cells. However, how commensal bacteria affect thymically derived fat-resident Treg cells that harbor a unique expression of peroxisome proliferator-activated receptor (PPAR)-γ and suppress inflammation in visceral adipose tissue (VAT), is not well defined. Here it is revealed that microbiota depletion causes a drastic decline in Treg cell population in VAT, particularly those expressing ST2 (ST2 Treg), which are largely restored after gut microbiome reconstruction.

Association of body roundness index with cardiovascular disease and all-cause mortality among Chinese adults.

Aims: To determine the impact of body roundness index (BRI) on the 10-year risk of cardiovascular disease (CVD) and all-cause mortality in Chinese adults.

Materials And Methods: We utilized data from a nationwide prospective cohort of 165 785 Chinese adults (aged ≥40 years, free of CVD and cancer at baseline), which was extracted from the China Cardiometabolic Disease and Cancer Cohort (4C).

Aim: We aimed to identify the characteristics of patients with diabetes who can derive cognitive benefits from intensive blood pressure (BP) treatment using machine learning methods.

Materials And Methods: Using data from the Action to Control Cardiovascular Risk in Diabetes Memory in Diabetes (ACCORD-MIND) study, 1349 patients with type 2 diabetes who underwent BP treatment (intensive treatment targeting a systolic BP <120 mmHg vs. standard treatment targeting <140 mmHg) were included in the machine learning analysis.

Gallstones, cholecystectomy, and cancer risk: an observational and Mendelian randomization study.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations.

Shared genetic architecture of type 2 diabetes with muscle mass and function and frailty reveals comorbidity etiology and pleiotropic druggable targets.

Background: Delineating the shared genetic architecture of type 2 diabetes with muscle mass and function and frailty is essential for unraveling the common etiology and developing holistic therapeutic strategies for these co-existing conditions.

Methods: In this genome-wide pleiotropic association study, we performed multi-level pairwise trait pleiotropic analyses using genome-wide association study summary statistics from up to 461,026 European ancestry individuals to dissect the shared genetic factors and causal relationships of type 2 diabetes and seven glycemic traits with four muscle mass- and function-related phenotypes and the frailty index.

Results: We first identified 27 pairs with significant genetic correlations through the linkage disequilibrium score regression and high-definition likelihood analysis.

Sex Difference and Socioeconomic Inequity in Chinese People With Hypertension: National Cross-Sectional Survey Study.

Diabetes in China part 2: prevention, challenges, and progress.

During the past 40 years, the prevalence of diabetes in China has increased from less than 1·0% in 1980 to 12·4% in 2018, an increase in line with the rapid growth of the nation's economy. To address such a burden, the Healthy China 2030 initiative and subsequent Action Plan, including a diabetes prevention and control campaign, were launched. A shift from a disease-centred approach to a health-centred approach and from treatment to prevention is the core of the Action Plan and diabetes management in China.

Diabetes in China part 1: epidemiology and risk factors.

The prevalence of diabetes in China is rapidly increasing. China now has the largest number of people living with diabetes worldwide, accounting for approximately one-quarter of the global diabetes population. Since the late 1970s, China has experienced profound changes and rapid economic growth, leading to shifts in lifestyle.

Participants were randomly allocated (1:1) to receive low-volume exercise or control by an online randomisation tool.

A brain-to-gut signal controls intestinal fat absorption.

Although fat is a crucial source of energy in diets, excessive intake leads to obesity. Fat absorption in the gut is prevailingly thought to occur organ-autonomously by diffusion. Whether the process is controlled by the brain-to-gut axis, however, remains largely unknown.

Magnetic silk fibroin nanospheres loaded with amphiphilic polypeptides and antibiotics for biofilm eradication.

The eradication of established biofilms is a highly challenging task, due to the protective barrier effect of extracellular polymeric substances (EPS) and the presence of persister cells. Both increased drug permeability and elimination of persister cells are essential for the eradication of biofilms. Here, magnetic silk fibroin nanospheres loaded with antibiotics and host defense peptide (HDP) mimics (MPSN/S@P) were developed to demonstrate a new strategy for biofilm eradication.
