They contain the RNA helicase enzyme, which plays a crucial role in the viral genome replication process. This work aims to develop and screen a potential molecule that could function as a dengue virus (DENV) RNA helicase inhibitor.Methods: The present study was performed by taking 26 potential derivatives of gedunin phytochemicals from the PubChem database as ligands. The binding of the compounds was analyzed by in silico docking considering DENV RNA helicase enzyme as the receptor.Results: After a thorough analysis of the docking scores, toxicity, and physicochemical properties, the compound tetrahydrogedunin was obtained as the best. Based on tetrahydrogedunin molecular structure, 100 drug-like molecules were designed using the Data Warrior tool. After screening for drug-likeness and ADMET properties, derivative number 42 was considered as promising. Further comparative docking of derivative 42 and a standard inhibitor molecule ST-610 with DENV RNA helicase enzyme showed binding affinity of 10.0 kcal/mol and -9.6 kcal/mol, respectively. The favorable interaction between DENV RNA helicase and derivative 42 was further validated by 50 nanoseconds molecular dynamics simulation and MM-GBSA analysis.Interpretation conclusion: Since the antiviral activity of derivative 42 has not been reported till date, the compound was predicted as a novel therapeutic molecule that can act against the dengue virus (DENV) RNA helicase enzyme.","PeriodicalId":17660,"journal":{"name":"Journal of Vector Borne Diseases","volume":" ","pages":"536-546"},"PeriodicalIF":0.8,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140849091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is prevalent in the Mediterranean basin, including the Maghreb region which comprises of Algeria, Tunisia, and Morocco. The environmental conditions in this area provide a suitable habitat for the proliferation of the phlebotomine sandfly, making it an endemic region for CanL. In this context, we carried out a systematic review and meta-analysis on the prevalence of canine leishmaniasis in these three Maghreb countries, identifying the risk factors for L. infantum infection. Data were collected from 27 papers published between 1973 and 2022 selected from five databases: PubMed, Google Scholar, ResearchGate, ScienceDirect and Scopus. Our selection criteria included both descriptive and analytical studies on canine leishmaniasis in Maghreb, as well as epidemiological studies that reported the prevalence of leishmaniasis infection. The meta-analysis was performed using Review Manager (RevMan) software version 5.4.1. based on predefined inclusion criteria. A total of 11,736 dogs were included in the analysis, among which 2481 were tested Leishmania positive cases. Over the years, the highest prevalence (68.32%) was recorded in Tiaret (Algeria) and the lowest (4.3%) in Tunisia. The examination of the risk factors revealed a heightened incidence of the disease in dogs of shepherd breeds, living in rural environments, displaying no apparent symptoms, and falling within the age range of 2 to 4 years. The findings presented in this study contribute a significant value to the exploration of leishmaniasis in this region, particularly by shedding light on the associated risk factors. Ultimately, substantial endeavors are warranted to enhance prevention, treatment, and overall control of the disease.","PeriodicalId":17660,"journal":{"name":"Journal of Vector Borne Diseases","volume":"61 4","pages":"515-524"},"PeriodicalIF":0.8,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142750865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study analyzed recent surveillance data to elucidate drivers of sustained transmission. A retrospective epidemiological study was conducted using malaria surveillance data from the Jazan region of Saudi Arabia over a 3-year period from January 2018 to December 2020.Methods: Deidentified records of all confirmed malaria cases reported across Jazan during the study period were obtained from Jazan Department of Health infectious disease surveillance system. Additional meteorological data was acquired to assess climatic correlates. The final analysis included 5255 confirmed cases that met the completeness criteria for key variables. Descriptive statistics characterized cases across demographic factors and spatial and temporal distributions. Correlations and linear regression modeling identified associations between monthly cases and weather parameters mapping visualized geographic patterns.Results: Of the 5255 confirmed cases, most were concentrated in Baish sector (50.8-72.0% annually), affected adult male foreigners (93.8-97.0%), peaked inconsistently across seasons, and were imported (85.4-94.9%). Non-Saudi nationalities had 6-fold higher incidence versus Saudi citizens in 2020 (677.6 vs 23.1 per 100,000). Monthly cases associated negatively with temperature (p=0.015) and positively with windspeed (p=0.005).Interpretation conclusion: Malaria persistence in Jazan involves geographic and demographic hotspots driven by imported infections and climate effects on vectors. Tailored programming aligned with evolving local dynamics will be essential to sustain elimination gains. Surveillance, optimized interventions, and flexible adaptation to high-risk locations and/or populations and meteorological influences are key priorities.","PeriodicalId":17660,"journal":{"name":"Journal of Vector Borne Diseases","volume":" ","pages":"614-621"},"PeriodicalIF":0.8,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141759549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It causes death in many poor and developing countries. Excluding vector control, Antimalarial drugs are the most reliable and effective weapon to tackle this severe disease. The emergence of antimalarial drug resistance in Plasmodium spp. becomes a barrier in Malaria elimination program as there has been no effective antimalarial vaccine till today. Apart from artemisinin, most of the antimalarial drugs have become resistant against malaria at present. Although, reduced efficacy of artemisinin-based combination therapy (ACT) has also been reported from southeast regions of Asia. Mutation of some genes within the parasite play a vital role in this drug resistance. Therefore, malaria is still a prime threat to human death and an unsolved problem. Newly emerging approaches like, vaccine development, plants based antimalarial drugs, nanoparticles, next generation antimalarial drugs should be taken & supported.
