Abstract

Introduction: Climate change is a critical driver of vector-borne diseases, notably dengue. Rising global temperatures, altered precipitation patterns, and increased extreme weather events enhance Aedes mosquitoes' habitats, the primary vectors of dengue. The pathogenesis of dengue, driven by any of the four serotypes of the dengue virus (DENV-1 to DENV-4), is exacerbated by climate-induced changes that support mosquito breeding and survival. Methods: This review analyzes selective studies from the last decade, integrating epidemiological data and climate models to explore the impacts of climatic variables on dengue dynamics. Adaptation strategies, including vaccination, vector control, and community-based interventions, were evaluated for their effectiveness in mitigating dengue transmission Results: Epidemiological data indicate approximately 390 million annual infections globally, with rapid urbanization and inadequate vector control compounding the issue. Climate models highlight significant increases in dengue incidence and shifts in its geographic distribution, particularly in regions such as the Americas, Asia, and potentially Europe. Promising adaptation strategies, such as the Communication for Behavioral Impact (COMBI) plan and constrained optimization models, have demonstrated efficacy in enhancing dengue prevention and control. Discussion: As climate change continues to alter ecosystems, integrating climatic data into public health strategies is essential for adaptive responses. Comprehensive and region-specific approaches, robust public health infrastructures, and international cooperation are paramount to address the rising threat of dengue. A need for international cooperation and robust public health infrastructure is necessary to address the multifaceted challenges posed by climate change on dengue transmission

Abstract

This study aimed to assess the nutritional and diabetes status of school teachers in Karawang. A cross-sectional study was conducted at the end of 2022. Of the 71 participants, 39.4% were overweight, 19.7% were obese, and 33.8% had a normal body mass index. In terms of fasting blood glucose levels, 73.2% were within the normal range, 12.7% had pre-diabetes, and 14.08% had diabetes. These findings highlight the high prevalence of overweight, obesity, and abnormal blood glucose levels among school teachers in Karawang, underscoring the need for targeted programs to promote healthy lifestyles and chronic disease prevention in this population.

Abstract

Antiviral Properties and Potential of Ginger (Zingiber Officinale) and Its Derivatives: A Systematic Review. Ginger has long been valued in traditional medicine for its therapeutic benefits. Recently, its antiviral capabilities have attracted significant interest, highlighting its potential as a natural antiviral agent. This systematic review seeks to thoroughly evaluate the antiviral effects of ginger and its active compounds, providing valuable insights to support future research and clinical applications in natural antiviral therapies. A comprehensive electronic search was undertaken across PubMed, Embase, and Scopus databases, employing MeSH terms, Emtree, and relevant synonyms to capture studies on ginger and its antiviral effects. The initial search yielded 531 records, which were de-duplicated and subsequently screened by title and abstract using Rayyan software. Fourteen studies specifically addressing antiviral effects against human pathogens met the inclusion criteria. This systematic review was conducted in strict accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to ensure rigorous reporting of findings. The majority of included studies were in vitro, revealing anti-viral effects of ginger against various viruses, including Influenza A, Chikungunya, Dengue, hRSV, HSV-2, and SARS-CoV-2 in different cell lines across various concentrations. In addition, Ginger extracts also demonstrated efficacy against Influenza A in both in vivo and in ovo studies, and a randomized controlled trial showcased encouraging antiviral effects targeting SARS-CoV-2. Ginger shows promising antiviral effects in most of the in vitro studies. Translating these findings to in vivo models is imperative for clinical relevance. Further in vivo research is essential before progressing to human studies to ascertain ginger's potential as an effective antiviral agent
