Background And Aim: Atrial fibrillation (AF) frequently coexists with other complications, including myocardial infarction (MI), heart failure (HF), stroke, and dementia. The contribution of metabolic dysfunction-associated steatotic liver disease (MASLD) to the development and mortality of AF was under-recognized. This study aims to investigate the impact of MASLD on the progression of AF and the mediating effect of carotid intima-media thickness (cIMT).

Yunnan Province is one of the provinces in China severely affected by HIV-1. To track the evolution and epidemiological characteristics of HIV-1 genetics in Yunnan Province, this study conducted a retrospective molecular epidemiological study of HIV-1 in new infections in Yunnan Province. From the newly reported HIV-infected individuals throughout Yunnan Province from January to March 2018, cases with CD4 T lymphocytes less than 200 cells/µL were excluded for BED capture enzyme immunoassay (BED-CEIA).

We aimed to explore the association between plant-based dietary (PBD) patterns and obesity trajectories in middle-aged and elderly, as well as obesity trajectories linked to cardiovascular disease (CVD) risk. A total of 7108 middle-aged and elderly UK Biobank participants with at least three physical measurements were included. Dietary information collected at enrolment was used to calculate the healthful plant-based diet index (hPDI).

Objective: To assess whether the Life's Essential 8 (LE8) score mediates the association of socioeconomic status (SES) with atrial fibrillation (AF) and heart failure (HF).

Methods: A total of 236,754 participants from the UK Biobank were included. SES was determined based on household income, education attainment, and employment status using latent class analysis.

What Is Already Known About This Topic?: The influence of population aging on the disability-adjusted life years (DALYs) associated with cardiovascular disease (CVD) is acknowledged, yet the magnitude of this impact remains unclear.

What Is Added By This Report?: This research quantified the influence of population aging on CVD DALYs from 1990 to 2021 through decomposition analysis. The findings revealed that the proportion of DALYs attributable to aging varied widely, ranging from ‒77.

Article Synopsis
  • The study aimed to explore the relationship between dietary and circulating antioxidant vitamins (A, C, E, and carotenoids) and the metabolic syndrome (MetS) while also assessing potential causality using Mendelian randomization (MR).
  • The research analyzed data from over 10,000 participants, finding that higher dietary intake of vitamins A, C, and carotenoids was associated with a lower incidence of MetS, while vitamin A and E levels may actually increase the risk.
  • The MR analysis further supported that a sufficient intake of vitamins A, C, and carotenoids can potentially reduce the risk of developing MetS, emphasizing the importance of these nutrients in dietary choices.

Accurate estimation of the distribution of POC in the sea surface is an important issue in understanding the carbon cycle at the basin scale in the ocean. This study explores the best machine learning approach to determine the distribution of POC in the ocean surface layer based on data obtained using satellite remote sensing. In order to estimate and verify the accuracy of this method, it is necessary to obtain a large amount of POC data from field observations, so this study was conducted in the Mediterranean Sea, where such data have been obtained and published.

Background: Researches have found that alteration of intestinal flora may be closely related to the development of autism spectrum disorder (ASD). However, whether probiotics supplementation has a protective effect on ASD remains controversial. This meta-analysis aimed to analyze the outcome of probiotics in the treatment of ASD children.

The purpose of this study was to investigate the relationship between oxidative stress and cognitive function, encompassing cognitive performance, intelligence, memory, reaction time, speech and vision by a bidirectional Mendelian randomisation study. Independent genetic variants associated with glutathione S-transferase (GST), catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPX), peroxiredoxin (PRDX), sulfhydryl oxidase (SOX) and thyroid peroxidase (TPO) were explored using a genome-wide association study (GWAS). The inverse variance weighted (IVW) or Wald ratio method was employed to ascertain the relationship between antioxidant enzymes and cognitive function.

High heritability and strong correlation have been observed in breast and ovarian cancers. However, their shared genetic architecture remained unclear. Linkage disequilibrium score regression (LDSC) and heritability estimation from summary statistics (ρ-HESS) were applied to estimate heritability and genetic correlations.

Purpose: Previous observational studies have suggested an association between sleep disturbance and metabolic syndrome (MetS). However, it remains unclear whether this association is causal. This study aims to investigate the causal effects of sleep-related traits on MetS using Mendelian randomization (MR).

Since the beginning of this century, there has been evidence of a rise in educational funding among the South Asian Association for Regional Cooperation (SAARC). However, there has been a decline in recent years despite South Asia being a highly populated and poverty-ridden region. Thus, the present study comes to assess how well the countries are doing in relation to the effect of educational funding on national development indicators, namely economic growth, human capital development, and the unemployment rate among the SAARC countries in the 21st century using Panel Nonlinear Autoregressive Distributed Lag (PNARDL) model formulated in Salisu and Isah (2017).

Article Synopsis
  • The study explored trends in hypertension prevalence, awareness, treatment, and control among US adults between 1999 and 2018, revealing an increase in hypertension prevalence from 33.53% to 40.58%.
  • Although the rate of new hypertension diagnoses decreased until 2014 and then slightly increased, awareness and treatment rates remained low, with only about 60% awareness and 51% control by 2018.
  • Key factors influencing hypertension outcomes included gender, income, education, and marital status, suggesting a need for targeted screening and prevention strategies for high-risk groups to improve health management.

Article Synopsis
  • Cell proliferation and differentiation are crucial for cell survival, and errors in these processes can lead to serious issues like cancer, birth defects, and degenerative diseases.
  • Recent research has identified histone methyltransferase DOT1L as a key regulator in these processes, influencing different forms of methylation on H3K79, which affects cell fate and proliferation.
  • DOT1L exhibits both pro-proliferative and tumor-suppressive effects in various contexts, making it a potential therapeutic target, though complete inhibition may lead to adverse effects.

Context: Observational studies have shown associations of birth weight (BW) with coronary heart disease (CHD), but results are inconsistent and do not distinguish the fetal or maternal effect of BW.

Objective: This study aims to explore the causal association between BW and CHD, analyze the fetal and maternal contribution, and quantify mediating effects of cardiometabolic factors.

Methods: Genetic variants from genome-wide association study summary-level data of own BW (N = 298 142), offspring BW (N = 210 267 mothers), and 16 cardiometabolic (anthropometric, glycemic, lipidemic, and blood pressure) factors were extracted as instrumental variables.
