Preconception and gestational versus postnatal exposure to air pollutants and risk of autism spectrum disorder: a systematic review and meta-analysis.

Purpose: The rising prevalence of ASD has prompted extensive research into potential environmental risk factors, with air pollution particularly emerging as a major concern. A systematic review and meta-analysis on the effect of air pollutants and time of exposure (particularly, PM, PM, NO, and O) and the risk of ASD was therefore performed.

Methods: Following PRISMA guidelines and PROSPERO registration (Ref: CRD42023464592), a thorough literature search was conducted across multiple databases, including Scopus, PubMed/MEDLINE, Embase, PsycINFO, Web of Science, and Cochrane Library.

Geospatial Distribution of HIV Seroprevalence Among Blood Donors in South Asian Countries: A Systematic Review and Meta-Analysis.

The reliance on replacement blood donors in developing countries has led to an increased prevalence of transfusion-transmitted infections (TTIs), including HIV. This systematic review and meta-analysis aimed to assess the seroprevalence of HIV among blood donors in South Asian countries and disseminate the findings in choropleth maps. In addition, gender-specific prevalence or the yearly trend of HIV prevalence among blood donors was also investigated.

Compressive strength assessment of concrete with brick chips using the CAPO-test.

This study presents the findings of an extensive investigation to evaluate the precision and reliability of a non-destructive CAPO-Test in estimating the in situ compressive strength of concrete made from machine-crushed brick aggregates. To estimate the compressive strength of concrete built from brick and stone aggregates for several target strengths at various ages, the CAPO-Test, core test, and standard cylinder test were used. The results of the core test and cylinder test are correlated with the CAPO pullout force, demonstrating a strong relationship between pullout force and compressive strength.

Knowledge, Attitudes, and Practices Toward the Prevention of COVID-19 in Bangladesh: A Systematic Review and Meta-Analysis.

Background: Numerous studies on knowledge, attitude, and practice (KAP) about the prevention of COVID-19 infections are available in Bangladeshi contexts, with results that vary significantly. However, no earlier attempt has been made to analyze the available COVID-19 KAP studies in Bangladesh, which is incorporated in this meta-analysis for the first time.

Methods: Following the PRISMA guidelines, articles relevant to COVID-19 KAP that were conducted among the Bangladeshi population were found in databases such as PubMed, Scopus, CINAHL, Google Scholar, and ResearchGate.
