Objectives
This scoping review synthesizes molecular evidence on Plasmodium genetic diversity and multiplicity of infection (MOI) in Southeast Asia and describes variation by species and epidemiological setting. Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines, we searched PubMed, Scopus, ProQuest, and EBSCO for English language, open-access observational studies published between January 1, 2015 until October 11, 2025. Included studies involved laboratory-confirmed human malaria and reported MOI and genetic diversity data derived from appropriate molecular genotyping methods. Findings were summarized by species, geography, markers, and clinical categories. Results: Sixteen studies were included, comprising 1,609 genotyped Plasmodium falciparum infections, 1,526 Plasmodium vivax infections, 37 Plasmodium malariae infections, and 188 human Plasmodium knowlesi infections. P. falciparum exhibited marked heterogeneity, with polyclonal infection rates ranging from 3.9% to 73.9% and mean MOI ranging from 1.05 to 4.9. P. vivax consistently showed high diversity, with polyclonal infection rates ranging from 16.9% to 71.4% and mean MOI ranging from 1.1 to 1.91, alongside expected heterozygosity values of 0.66–0.87. P. malariae displayed low MOI, whereas P. knowlesi showed polyclonal infection rates ranging from 7.3% to 21% and mean MOI ranging from 1.04 to 1.06. No data were available for Plasmodium ovale. Conclusion: P. falciparum and P. vivax remain genetically diverse across Southeast Asia, with heterogeneous transmission patterns, particularly in border regions. Limited data on P. malariae, human P. knowlesi, and P. ovale highlight the need for standardized molecular surveillance to support targeted elimination efforts.

Objectives
This review and meta-analysis examined the effectiveness of non-pharmacological therapies delivered through school-based interventions for smoking cessation among adolescents in South and Southeast Asian countries.
Methods
A systematic search was conducted across PubMed, Scopus, Science Direct, BioMed Central, the Cochrane Library, and ProQuest Dissertations & Theses Global from inception to October 2024. Eligible studies comprised randomized controlled trials and quasi-experimental studies that compared non-pharmacological smoking cessation interventions delivered in schools or other educational institutions. Data on smoking abstinence outcomes were extracted from published studies, and odds ratios (ORs) with 95% confidence intervals (CIs) were pooled using a random-effects model via the Mantel-Haenszel estimator.
Results
Seven studies involving 1,260 participants were included. The meta-analysis demonstrated that non-pharmacological school-based therapies significantly increased smoking abstinence compared to controls (OR, 2.83; 95% CI, 1.83–4.40; p<0.001. Subgroup analyzes revealed benefits across both randomized controlled trials and quasi-experimental studies with varying abstinence rates. Studies utilizing biochemical verification showed significant positive effects despite substantial heterogeneity, and short-term (<3 months) abstinence was significantly higher in intervention groups compared to controls. Overall, no differences were found between subgroups regarding intervention effectiveness.
Conclusion
This meta-analysis indicates that non-pharmacological school-based interventions positively impact smoking abstinence rates, although effectiveness may vary based on study design, follow-up duration, and use of biochemical verification. The findings underscore the need for further research with larger sample sizes, extended follow-up periods, and improved methodological rigor in these regions.

Objectives
This study compared the research output of Association of Southeast Asian Nations (ASEAN) countries to understand research trends and clarify past, present, and future patterns using scientometric techniques.
Methods
This scientometric study systematically mined health and social science publications from the Web of Science and Scopus databases using keywords associated with infectious disease. The analysis included only English-language articles and review articles by authors from any ASEAN country. Publication, citation, and text co-occurrence network analyses were performed. R Studio and VOSviewer enabled data management, analysis, and visualization.
Results
Searches identified 12,511 articles published between 1925 and 2022, with a notable increase in research publications since 2003. The leading journals on infectious disease were associated with established publishing houses, including BMC, BMJ, and The Lancet. The most-cited articles were primarily global burden of disease studies, with 7,367 citations. Among ASEAN countries, Thailand, Malaysia, and Singapore had the most publications and collaborative efforts on the topic. Analysis of keyword co-occurrence revealed clusters related to global health, dengue, bacterial studies, non-dengue viral topics, and diagnostics. Most early studies examined diagnostics, gene and sequencing methodologies, and virology; later, the focus shifted toward herbal and alternative medicine.
Conclusion
Recently, the research capacity of Southeast Asia has expanded dramatically, with substantial contributions from high-income countries. Intense cooperation between member states is essential, emphasizing the role of HICs in supporting their neighbors. Increased research efforts and collaboration must be dedicated to innovative approaches to combat persistent health conditions, along with emerging issues like climate change.
