Citizen surveillance has been demonstrated as an effective alternative strategy, increasing the possibility of monitoring vector populations on a broad geographic scale. Thus, our study aimed to explore a database built from pictorial/video records and specimens sent through citizen participation, identify the main groups confused with triatomines, and systematize the data on insect diversity.Methods: Due to demand from the local community, the \"WhatsBarb\" project was established using a digital platform application, to receive photos of suspected insects, or triatomines, and provide digital campaigns, with instructions for collecting insects and delivery to Entomological Surveillance Services.Results: In total, 465 insect records were obtained between 2019 and 2024. We identified taxonomic orders and families in 464 and 454 records, respectively, and estimated at least 68 genera, 42 species, and 101 distinct taxa. Triatomines represented 32.3% of the volunteer contacts. Records showed a predominance of true bugs (Hemiptera: Heteroptera), including phytophagous species and predator reduviids (54.6%; n=254). Contacts were received from 20 of the 26 states in Brazil, in addition to the Federal District.Conclusions: Our findings demonstrate the power of digital tools in public health, which could aid in describing, preventing, and controlling CD vectors, and could be applied to other neglected diseases.","PeriodicalId":21199,"journal":{"name":"Revista da Sociedade Brasileira de Medicina Tropical","volume":"58 ","pages":"e004032025"},"PeriodicalIF":1.8,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11956169/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143764778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, such MIC data are insufficient to measure antifungal susceptibility if a strain is heteroresistant to the tested drug. In such cases, a minority subpopulation of fungal cells, originating from an initially susceptible lineage, can grow at antifungal drug concentrations above the MIC. In studies on fluconazole heteroresistance in Cryptococcus spp., chromosomal disomy has been shown to result in the overexpression of two genes located on chromosome 1 (Chr1) linked to antifungal resistance: ERG11 and AFR1. This review addresses the underlying mechanisms of antifungal resistance, the evolution of methods for determining antifungal susceptibility, and the clinical implications of Cryptococcus heteroresistance to fluconazole. The analysis of the findings indicated a correlation between heteroresistance and adverse clinical outcomes, although this observation still lacks definite confirmation in the literature. This highlights the need to implement more efficient therapeutic strategies and improve antifungal susceptibility and heteroresistance testing.","PeriodicalId":21199,"journal":{"name":"Revista da Sociedade Brasileira de Medicina Tropical","volume":"58 ","pages":"e002002025"},"PeriodicalIF":1.8,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11941007/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143711192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Morocco, various forms of extrapulmonary tuberculosis are prevalent. This systematic review examines research findings on the prevalence, risk factors, and treatment outcomes of extrapulmonary tuberculosis in Morocco.Methods: We conducted searches for observational studies on extrapulmonary tuberculosis in Morocco, published between January 1991 and February 2023, using Scopus, ScienceDirect, and PubMed databases. Medical Subject Heading keywords were used to guide the search.Results: This review included 18 studies focusing on different forms of extrapulmonary tuberculosis, such as cold abscesses, lymph nodes, meningeal, cutaneous, osteoarticular, genital, breast, and gastrointestinal tuberculosis. These studies provided insights into the clinical, diagnostic, and therapeutic aspects of these extrapulmonary tuberculosis forms. Prevalence data were limited, and treatment outcomes varied considerably across studies. The only study providing prevalence data for all forms of extrapulmonary tuberculosis reported a prevalence of 43.5% among tuberculosis cases in Larach Province. Treatment success rates ranged from 64.7% to 100%. Common risk factors included low socioeconomic status, diabetes mellitus, pulmonary tuberculosis exposure, and HIV co-infection.Conclusions: This review highlights a lack of comprehensive on the prevalence of extrapulmonary tuberculosis in Morocco, with inconsistent findings on risk factors and treatment outcomes. Further controlled studies are recommended to obtain more robust evidence and inform more effective management strategies for extrapulmonary tuberculosis.","PeriodicalId":21199,"journal":{"name":"Revista da Sociedade Brasileira de Medicina Tropical","volume":"58 ","pages":"e004022024"},"PeriodicalIF":1.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11922330/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143711188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Flight ability varies between individuals (males and females) of the same species, and wing shape modifications may be associated with the flight capacity of these vectors. Therefore, studies on this topic are crucial for the early identification of species with a greater propensity to invade human dwellings and for the implementation of appropriate surveillance and vector control strategies. However, even when exposed to the same nutritional and environmental conditions, triatomines demonstrate a range of flight abilities. To date, it remains unclear whether differences in wing morphology play a decisive role in determining this behavior. As an initial approach to addressing this issue, the present study aimed to determine whether morphometric differences exist in the wings of flying and non-flying individuals from six species of the genus Triatoma: Triatoma costalimai, Triatoma klugi, Triatoma matogrossensis, Triatoma rubrovaria, Triatoma vandae, and Triatoma williami.Methods: This study employed geometric morphometrics to investigate differences in wing size and shape between flying and non-flying individuals from six Triatoma species.Results: The findings indicated a variation in wing size between sexes. Additionally, shape variations were observed between flying and non-flying insects, particularly in females.Conclusions: Geometric morphometrics effectively identified distinct wing shape patterns in flying and non-flying specimens from six Triatoma species, revealing differences that may aid in identifying species with greater active dispersal capacity.","PeriodicalId":21199,"journal":{"name":"Revista da Sociedade Brasileira de Medicina Tropical","volume":"58 ","pages":"e007002024"},"PeriodicalIF":1.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11922331/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143711201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rapid and unprecedented anthropogenic, behavioral, and social transformations witnessed in the past century have expedited the emergence of novel pathogens, intensifying their impact on the global human population.Methods: This study aimed to comprehensively analyze and compare the genomic sequences of four distinct viruses: SARS-CoV-2, SARS, MERS, and Ebola. Advanced genomic sequencing techniques and a Gated Recurrent Unit-based deep learning model were used to examine the intricate genetic makeup of these viruses. The proposed study sheds light on their evolutionary dynamics, transmission patterns, and pathogenicity and contributes to the development of effective diagnostic and therapeutic interventions.Results: This model exhibited exceptional performance as evidenced by accuracy values of 99.01%, 98.91%, 98.35%, and 98.04% for SARS-CoV-2, SARS, MERS, and Ebola respectively. Precision values ranged from 98.1% to 98.72%, recall values consistently surpassed 92%, and F1 scores ranged from 95.47% to 96.37%.Conclusions: These results underscore the robustness of this model and its potential utility in genomic analysis, paving the way for enhanced understanding, preparedness, and response to emerging viral threats. In the future, this research will focus on creating better diagnostic instruments for the early identification of viral illnesses, developing vaccinations, and tailoring treatments based on the genetic composition and evolutionary patterns of different viruses. This model can be modified to examine a more extensive variety of diseases and recently discovered viruses to predict future outbreaks and their effects on global health.","PeriodicalId":21199,"journal":{"name":"Revista da Sociedade Brasileira de Medicina Tropical","volume":"58 ","pages":"e004012024"},"PeriodicalIF":1.8,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11805527/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143399888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The amplitudes of each QRS were analyzed, and the sum of the DII and V5 derivations of the ADOC index and the arithmetic means of the QRS complexes in the frontal and horizontal planes were determined.Results: The ADOC index was correlated with the highest risk of stroke and death according to the Rassi score. The ADOC index (p=0.046) and mean mQRS were inversely proportional to the Rassi risk of death score (p=0.038). The ADOC index proved to be more sensitive (75.0%) and accurate (67.4%) in identifying patients at elevated death risk using the Rassi score.
