Unlabelled: Deciphering the heterogeneity of type 2 diabetes in prognosis and treatment effect is essential. We used a novel dimensionality reduction approach to describe the type 2 diabetes phenotype continuum and visualize the difference in lifestyle intervention efficacy in Chinese patients. Based on 17,816 participants with newly diagnosed type 2 diabetes (aged ≥40 years) from a nationwide cohort, 12 key phenotypes were residualized for age and sex to construct a two-dimensional tree structure.

This study aimed to identify distinct phenotypes and evaluate their links to future cardiometabolic risks in a large Chinese cohort.
Methods: The discriminative dimensionality reduction with trees (DDRTree) algorithm was used to develop a tree structure based on nine clinical variables.
Current obesity classifications may not adequately reflect age- and gender-specific risks in diverse populations. In a prospective cohort study of 166,285 Chinese adults aged ≥40 years without prior cardiovascular disease (CVD) or cancer, we evaluate optimal thresholds of body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR) for predicting incident CVD and all-cause mortality. We observe monotonically increasing dose-response associations of BMI, WC, and WHR with CVD risk but U-shaped relationships with all-cause mortality.

This study employed genetic approaches to identify GM taxa exerting causal effects on longevity and aging and assess the mediation role of cerebrospinal fluid (CSF) proteins. We leveraged summary statistics of the GM taxa (207 taxa, 7738 participants from the Dutch Microbiome Project), the CSF proteins (7008 aptamers, 3506 participants), and the longevity and aging phenotypes (UK Biobank, Longevity Genomics, and Edinburgh DataShare) from the largest genome-wide association studies so far.

Background: The association between muscle function and dementia risk remains elusive, as studies suggest that impaired muscle function may act as both a risk factor for and a consequence of dementia, hindering causal inference.
Objectives: We aimed to clarify the temporal relationship between muscle function and incident dementia by investigating non-linear trajectories of muscle function in the years preceding dementia onset in older US and European populations.
Design: Case-control study.
Prediabetes, an intermediate stage of developing diabetes, exhibits considerable phenotypic heterogeneity. Here, we apply the Discriminative Dimensionality Reduction Tree (DDRTree) algorithm to explore prediabetes heterogeneity in 55,777 participants from the China Cardiometabolic Disease and Cancer Cohort (4C) study. Based on 12 clinically available variables, we identify four distinct phenotypes and observe differential risks of type 2 diabetes mellitus (T2DM), chronic kidney disease (CKD), and cardiovascular disease (CVD).

Background: Although socioeconomic inequality in mortality has long been a public health focus, the associations of area-level socioeconomic status (SES) and individual-level factors with mortality have not been well investigated, especially in China with rapid industrial development.
Methods: In this nationwide, population-based, prospective cohort study, adults aged over 40 from 29 counties were included in the China Cardiometabolic Disease and Cancer Cohort study. The composite area deprivation index of area-level SES was generated from national census data and categorised into tertiles.
This study examined the differences in physico-chemical, volatile and sensory characteristics between the ciders made with the juices from four apple cultivars (Golden delicious, Fuji, Ralls genet, and Xiushui) and the ciders prepared with corresponding pomaces. These cider characteristics varied with apple cultivar and fermentation raw material, with fermentation raw material imparting more influence. Compared with ciders made with apple juices, the counterparts of apple pomaces showed higher contents of total sugar (2.

Data Sources: PubMed, Embase, and the Cochrane Library (CENTRAL) were searched for randomized controlled trials of 3 degrees of CER diet regimens and 4 categories of IF diet regimens, from inception of the databases to December 2022.
Background: Definition and staging rationale of cardiovascular-kidney-metabolic syndrome were developed. The utility of cardiovascular-kidney-metabolic construct in risk stratification and target strategies of health and behavior modifications needs to be addressed. The study aims to investigate the individual and combined associations of cardiovascular-kidney-metabolic stage and cardiovascular health (CVH) by Life's Essential 8 (LE 8) with incident cardiovascular events (CVD), and determine the distribution and contribution of domain-specific CVH across cardiovascular-kidney-metabolic stages.

Background: Delineating the causal chain effects of reproductive traits and fat- and muscle-related traits on cardiovascular disease (CVD) is essential for optimizing precision prevention and control of cardiovascular health in women.
Methods: In this study, we applied the two-sample Mendelian randomization (MR) analyses and two-step MR framework to investigate the causal chain effects and the mediating effect pathways among reproductive factors and fat- and muscle-related traits on CVD outcomes in women, applying the genome-wide association study summary statistics of 16 women's reproductive traits across puberty and pre-pregnancy, pregnancy and postpartum, and menopausal transition stages, 16 women's fat- and muscle-related traits, and five CVD outcomes of coronary artery disease (CAD), myocardial infarction (MI), heart failure, atrial fibrillation, and ischemic stroke (IS) from over one million individuals of European descent.
Results: The MR analyses revealed the associations of genetically predicted nine reproductive traits (i.
Identifying factors affecting lifespan, including genes or proteins, enables effective interventions. We prioritized potential drug targets and provided insights into biological pathways for healthy longevity by integrating Mendelian randomization, cohort, and experimental studies. We identified causal effects of tissue-specific genetic transcripts and serum protein levels on three longevity outcomes: the parental lifespan, the top 1% and 10% extreme longevity, utilizing Mendelian randomization and multi-traits colocalization, combining the latest genetics data of gene expression (eQTLGen and GTEx) and proteomics (4746 proteins from five studies).

Aims: Intensive systolic blood pressure (BP) control is associated with a lower risk of cardiovascular disease (CVD) but an increased risk of worsening renal function (WRF). This study aimed to investigate whether intensive BP control should be continued after WRF.
Methods: We performed a post hoc analysis of SPRINT (Systolic Blood Pressure Intervention Trial).
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.
