METHODS: Using predefined keywords, we searched online databases, including Scopus, PubMed, Web of Science Core Collection, and Google Scholar, for relevant studies published from inception through July 2024. A random-effects meta-analysis was then employed to pool the weighted mean differences (WMD) and 95% CI for outcomes assessed by a minimum of three studies.
RESULTS: Initially 1,205 studies were obtained out of which 25 RCTs were decided to be included for further analyses. Selenium supplementation reduced VLDL (WMD: -1.53; 95% CI: -2.86, -0.20), but did not change TG (WMD: 1.12; 95% CI: -4.51, 6.74), TC (WMD: -2.25; 95% CI: -6.80, 2.29), LDL-C (WMD: 1.60; 95% CI: -4.26, 7.46), and HDL-C levels (WMD: 0.98; 95% CI: - 0.02, 1.98).
CONCLUSION: Our study showed significantly reduced VLDL but limited effects were observed in other lipid indexes. More extensive RCTs are required globally to achieve a holistic comprehension of the connection between selenium and lipid profile.
METHODS: A literature search was conducted across databases including PubMed, Embase, Web of Science, and Cochrane on October 20, 2023. The included studies reported the number of pregnant women and the count of those who were dual users. Quality assessment was undertaken using the JBI tool. The pooled prevalence of dual use was determined via a random-effects model. All statistical analyses were executed using R software, version 4.3.
PROSPERO: CRD42023486020.
RESULTS: Eighteen studies were analyzed, encompassing 5,983,363 pregnant women. The meta-analysis indicated an overall prevalence of 4.6% (95% CI: 2.0-10.3) for dual users with significant heterogeneity (I2 = 100%). Subgroup analysis based on the country showed a prevalence of 4.9% (95% CI: 2.0 to 11.6) for USA and 8.1% (95% CI: 0.00 to 1.00) for UK. Meta-regression revealed reduction of prevalence of dual use from 2019 to 2023. A potential publication bias was indicated by the LFK index and the Doi plot.
CONCLUSION: The dual consumption of e-cigarettes and traditional tobacco in pregnant women is a significant health concern, with a notable prevalence. Given the established risks of tobacco smoking during pregnancy and the uncertainties surrounding e-cigarettes, more comprehensive research and public health interventions are urgently needed to address this issue.
METHODS: A systematic search of PubMed, Web of Science, and Embase was conducted for studies published up to August 2024. Eligibility criteria included cohort, case-control, and cross-sectional studies assessing air pollution exposure and mortality in PLWH. Nested-Knowledge software was used for screening and data extraction. The Newcastle-Ottawa Scale was applied for quality assessment. A narrative approach and tabular summarization were used for data synthesis and presentation.
RESULTS: Nine studies, mostly from China, demonstrated a significant association between long-term exposure to PM1, PM2.5, and PM10 and increased risks of AIDS-related and all-cause mortality in PLWH. Hazard ratios for mortality increased by 2.38-5.13% per unit increase in PM concentrations, with older adults (> 60), females, and those with lower CD4 counts (
