We conducted a scoping review to explore the determinants and impacts of AMR within the beef value chain in SSA, highlighting the challenges and progress in mitigating AMR risks in livestock production. This review identifies key factors contributing to AMR, including the overuse and misuse of antimicrobials, inadequate veterinary oversight, and weak regulatory frameworks. These practices are prevalent across various stages of the beef value chain, from farm to slaughterhouse, and are exacerbated by informal markets and insufficient infrastructure. Our findings also highlight the role of environmental factors, such as contamination of feed, water, and manure, in the spread of resistant pathogens. Additionally, gaps in AMR surveillance, education, and enforcement limit effective control measures in the region. While efforts to combat AMR have gained momentum in some countries, including the development of national action plans and surveillance systems, substantial challenges remain. These include poor adherence to antimicrobial guidelines, insufficient veterinary training, and the lack of integration between sectors. There is a need for targeted research to better understand antimicrobial misuse, socio-economic drivers, and the environmental pathways of AMR, as well as the need for stronger regulatory frameworks and cross-border cooperation. Addressing these challenges will be essential to safeguarding food safety, public health, and the sustainability of the beef industry in SSA.</p>","PeriodicalId":23330,"journal":{"name":"Tropical Medicine and Infectious Disease","volume":"10 3","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11945503/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143731670","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}

This study investigated the clinical characteristics of MDR-TB patients with concurrent NTM infection during treatment. A retrospective cohort study was conducted to collect the clinical data of MDR-TB patients who initiated treatment between January 2020 and December 2022. A total of 389 patients were analyzed, among which 111 patients who were lost to follow-up and 56 patients who missed etiological examination of tuberculosis during the visit period were excluded. A total of 222 patients with complete data were included in this study. The species identification method primarily employed molecular biology techniques, specifically the DNA microarray method and/or MPB64 antigen detection using the colloidal gold method. Patients whose sputum or bronchoalveolar lavage fluid cultures were positive and who were identified at least once as having NTM or as MPB64 negative were included in this study. Imaging data, comorbidities, pre-treatment infection, and nutritional indicators were analyzed during treatment. Among the 222 MDR-TB patients, no concurrent NTM cases were identified at the beginning of treatment. However, 19 cases (8.56%) were presumed to be NTM-positive during treatment, which appeared during anti-tuberculosis treatment from 2 to 12 months, averaging 6 (3, 12) months. Thirteen patients were only tested for MPB64, with five having two negative MPB64 tests. The symptoms of NTM-positive patients varied, and imaging findings were similar to those of MDR-TB but did not worsen. The emergence of presumed NTM-positive cases (8.56%) among MDR-TB patients during treatment highlights the need for monitoring, as symptoms and imaging findings may mimic MDR-TB without worsening. Early and repeated testing, including methods beyond MPB64, may be useful for more accurate diagnosis and tailored management.</p>","PeriodicalId":23330,"journal":{"name":"Tropical Medicine and Infectious Disease","volume":"10 3","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11946490/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143731695","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}

Here, we evaluated the surveillance data collected over the last decade in Nigeria (2014-2023). A spatio-temporal model was developed using the NIMBLE (1.2.1) package in R to assess outbreak risk. Our analysis found a high risk of canine rabies outbreaks in Plateau state and its surrounding states, as well as increased trends of outbreaks from July to September. The high number of reported canine rabies outbreaks in the North Central region could be due to cross-border transmission or improved reporting in the area. However, this could be confounded by potential reporting bias, with 8 out of 37 states (21.6%) never reporting a single outbreak in the period studied.

TasP calls for the immediate initiation of fully subsidized and supported antiretroviral therapy (ART) following HIV diagnosis. TasP effectively prevents progression to AIDS, and premature AIDS-related deaths among people living with HIV (PLWH), and simultaneously renders HIV non-transmissible, thus preventing onward HIV transmission. In addition, PrEP has proven effective against HIV transmission among high-risk individuals who are adherent to the regimen. PrEP traditionally consists of two antiretrovirals given orally as one pill daily: originally, tenofovir-DF plus emtricitabine (TDF-FTC), and later, tenofovir-AF (TAF) plus FTC (more recently, other options have become available, including long-acting parenteral formulations; however, these are still of limited availability). Over the last two decades, the province of British Columbia has rolled out TasP among all PLWH, and starting in 2018, PrEP was added as a strategy to reach individuals most at risk of acquiring HIV to further accelerate progress in addressing HIV/AIDS as a public health threat. Our \"generalized TasP + focused PrEP\" program proved to be synergistic (or multiplicative) as it relates to reducing the HIV effective reproduction number (Re). TasP lowers HIV incidence by reducing the pool of individuals able to transmit HIV, which is dependent on the extent of community plasma viral load (pVL) suppression. Meanwhile, PrEP reduces the number of potential new infections among those most susceptible to acquiring HIV in the community, independent of viral load suppression among PLWH. Our results strongly support widespread implementation of the combination of \"generalized TasP + focused PrEP\" strategy and underscore the importance of long-term monitoring of Re at a programmatic level to identify opportunities for optimizing TasP and PrEP programs. This approach aligns with the United Nations goal of \"Ending HIV/AIDS as a pandemic by 2030\", both in Canada and globally.</p>","PeriodicalId":23330,"journal":{"name":"Tropical Medicine and Infectious Disease","volume":"10 3","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11945595/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143731773","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}
