Observational studies indicate that tea intake is associated with a decreased risk of kidney stones. Here we performed a mendelian randomization (MR) analysis to evaluate whether this association is causal. ⋯ This study suggests that tea intake may be causally associated with a decreased risk of kidney stones.

Green tea consumption and the risk of stroke: A systematic review and meta-analysis of cohort studies.
Epidemiologic studies are inconsistent regarding the association between green tea consumption and the risk of stroke. We performed a meta-analysis to determine whether an association exists between them in cohort studies. ⋯ This meta-analysis suggests that green tea consumption is inversely associated with the risk of stroke, especially among those with moderate consumption. Our results support recommendations for green tea consumption to the primary prevention of stroke.

Intake of ultra-processed foods and sleep-related outcomes: A systematic review and meta-analysis.
The aim of this review article was to evaluate the association between the intake of ultra-processed foods and sleep-related outcomes through a systematic review and meta-analysis. Pubmed, LILACS, Scielo, Scopus, Embase, and Web of Science were searched on December 31, 2021, for studies that evaluated the association between ultra-processed foods and sleep-related outcomes (self-reported sleep duration and quality). Pooled odds ratios were assessed through a random-effects model; heterogeneity was evaluated using the I2 statistic. ⋯ When adjusted for cofounders, we found statistically significant results for all ages. The high intake of ultra-processed foods was associated with sleep-related outcomes, with moderate credibility of the evidence. Longitudinal studies and clinical trials confirming these findings are necessary.

Plasma phospholipid arachidonic acid in relation to non-alcoholic fatty liver disease: Mendelian randomization study.
The role of plasma phospholipid arachidonic acid (AA) in the development of non-alcoholic fatty liver disease (NALFD), cirrhosis, and liver cancer remains unclear. This study aimed to determine the causality of the associations of plasma phospholipid AA with NALFD, cirrhosis, and liver cancer using Mendelian randomization analysis. ⋯ This study suggests potential causal associations of high levels of plasma phospholipid AA with the risk of NAFLD and cirrhosis.

Prognostic values of myosteatosis for overall survival in patients with gastric cancers: A meta-analysis with trial sequential analysis.
Gastric cancer is among the most common and lethal cancers worldwide. Recently, studies have reported that myosteatosis is a prognosticator for adverse survival outcomes in patients with gastric cancer, but with inconsistent conclusions. Therefore, this meta-analysis aimed to systematically quantify the predictive power of myosteatosis for overall survival in the gastric cancer setting. ⋯ Myosteatosis was identified as a strong predictor of reduced overall survival in the gastric cancer population.
