This umbrella review was conducted aiming to assess the association between genetic variations and the development of diabetic retinopathy (DR) by collecting and evaluating available systematic reviews and meta-analysis results. We evaluated the methodological quality using the Measurement Tool to Assess Systematic Reviews (AMSTAR) 2.0, estimated the summary effect size by using the random effects model and calculated the 95% prediction intervals (PIs).

College students seem to be more vulnerable to the adverse effects of stress, which makes them more at risk of suffering from mental disorders. This umbrella review aimed to evaluate the credibility of published evidence regarding the effects of interventions on mental disorders among university students.

Expert Rev Vaccines
December 2023
Article Synopsis
- There is a notable gap in existing literature on effective hepatitis B vaccine (HepB) strategies, prompting a thorough exploration of their efficacy and safety across different populations.
- A review of 21 meta-analyses highlighted strong evidence supporting the use of HepB boosters and the HBsAg-1018 adjuvant for better immunity, while both targeted and universal vaccinations can lower HBV infection rates.
- Factors like obesity and specific genetic variations can influence the effectiveness of the vaccine, but overall, tailored vaccination approaches appear beneficial for combating hepatitis B without significant adverse reactions.
Article Synopsis
- An umbrella review was conducted to evaluate the effectiveness of ketogenic diets (KD) based on a comprehensive analysis of 23 meta-analyses found in major health databases.
- The findings indicate that KD may lead to increased cholesterol levels and improved weight loss when combined with physical activity, and it shows potential in reducing seizures in children with refractory epilepsy.
- However, the overall strength of evidence is considered weak, highlighting the need for more rigorous research to confirm the diet's effectiveness for various health conditions.
The present systematic review and meta-analysis aimed to summarize the associations between gut microbiota composition and non-alcoholic fatty liver disease. To compare the differences between individuals with or without NAFLD, the standardized mean difference and 95% confidence interval were computed for each α-diversity index and relative abundance of gut microbes. The β-diversity indices were summarized in a qualitative manner.

This study analyzes dietary patterns and single nucleotide polymorphisms (SNPs) in 543 diabetes patients with new-onset cardiovascular events and 461 diabetic patients without.
Methods And Results: SNPs are determined and analyzed using real time PCR and gene chip method.
Birth spacing and risk of adverse pregnancy and birth outcomes: A systematic review and dose-response meta-analysis.
Acta Obstet Gynecol Scand
December 2023
Introduction: The association between extreme birth spacing and adverse outcomes is controversial, and available evidence is fragmented into different classifications of birth spacing.
Material And Methods: We conducted a systematic review of observational studies to evaluate the association between birth spacing (i.e.
Article Synopsis
- A study aimed to investigate the relationship between dietary branched-chain amino acid (BCAA) intake and cardiovascular disease (CVD) risk among type 2 diabetes patients in China, as previous research had inconsistent findings.
- The research included 419 type 2 diabetes patients, comparing those with CVD to those without, utilizing a food frequency questionnaire to assess dietary BCAA intake.
- Results indicated that higher intake of total BCAA and individual amino acids like leucine significantly reduced the risk of CVD, with specific foods including whole grains and dairy contributing to this protective effect.
The Przewalski's gazelle (Procapra przewalskii) is one of the most endangered ungulates in the world, with fewer than 2,000 individuals surviving in nine habitat fragments on the Qinghai-Tibet Plateau and isolated by human settlements and infrastructure. In particular, the Qinghai-Tibet railway, which crosses the largest part of the gazelle's distribution, remains a major concern because of its potential to intensify landscape genetic differentiation. Here, using mtDNA sequencing and microsatellite genotyping to analyze 275 Przewalski's gazelle samples collected throughout the range, we observed low level of genetic diversity (mtDNA π = 0.
