The timing and coordination of interventions and the use of booster doses to prevent disease resurgence are all important. Dynamic models are useful for simulating outbreaks and can foster proactive, evidence-based public health planning, thereby supporting the shift from reactive to anticipatory strategies in alignment with the Global Task Force on Cholera Control's 2030 cholera roadmap. Continuous refinement of the model with real-world data will enhance its global applicability and help advance effective disease control strategies.</p>","PeriodicalId":9465,"journal":{"name":"Bulletin of the World Health Organization","volume":"103 10","pages":"607-618"},"PeriodicalIF":5.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12477517/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145205634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the existence of effective and affordable medicines for Parkinson disease, access to these medicines is limited in the World Health Organization (WHO) African Region. Several factors influence accessibility, including lack of prioritization of Parkinson disease, shortage of a trained health workforce, barriers to health financing and lack of inclusion of medicines in national essential medicines lists. We determined alignment of the most recent national essential medicines lists of 47 countries in the WHO African Region with the 23rd edition of the <i>WHO Model list of essential medicines</i> for Parkinson disease medicines. Overall, of any formulation or strength, 81% (38/47) of countries included levodopa + carbidopa or levodopa + benserazide as a therapeutic alternative on their national lists; and 79% (37/47) included biperiden or trihexyphenidyl as a therapeutic alternative. Inclusion of specific formulations for medicines was lower; for example, 45% (21/47) of countries included levodopa + carbidopa or levodopa + benserazide in a 4:1 ratio. Furthermore, 11% (5/47) of national essential medicines lists included none of the four medicines. While inclusion of medicines for Parkinson disease in national essential medicines lists provides no guarantee of immediate access, it can encourage procurement, prescribing and use, and can help lower costs, raise awareness of and create political will for Parkinson disease treatment. This analysis provides further evidence of the need for action to improve the accessibility of medicines for Parkinson disease in the WHO African Region.</p>","PeriodicalId":9465,"journal":{"name":"Bulletin of the World Health Organization","volume":"103 10","pages":"626-634"},"PeriodicalIF":5.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12481222/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145205683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, when treatment effects are likely to differ between populations, for example due to differences in the disease, population characteristics or health-care systems, this approach can lead to misleading conclusions and raise ethical concerns. Justice is compromised when research conducted in low-resourced countries benefits primarily or exclusively populations of wealthier countries. A clinical trial design and analysis that focuses on estimating a single treatment effect, assumed to apply to all participating populations, goes against the ethical principle of justice and the positions of the World Health Assembly. To address this issue, we suggest a methodological strategy based on hierarchical modelling. This approach enables researchers to estimate treatment effects that are valid for each participating population, while potentially retaining efficiency comparable to traditional pooled analysis, as we demonstrate in an example. When substantial between-population differences exist, it produces valid, region-specific results. Strategies such as this one, if adopted into the standards for global trials, would allow regulators, funders and other stakeholders to ensure that trials are designed to help preserve justice for all participant populations.</p>","PeriodicalId":9465,"journal":{"name":"Bulletin of the World Health Organization","volume":"103 10","pages":"619-625"},"PeriodicalIF":5.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12477512/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145205649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
