It results in severe physical, psychological and financial consequences. Heart and Sole Africa (HASA) is a non-governmental, community-based organization providing management to podoconiosis patients in Rwanda. We sought to analyze the impact of their program on the lives of patients.Methods: Quantitative surveys recorded the participants' demographics, adherence to HASA's management recommendations and changes in quality of life (QOL). Qualitative questions were used to gather respondent perspectives on HASA programming.Results: We interviewed 127 patients from HASA's Musanze (n=47) and Burera (n=80) clinics. Almost all participants (98.4%) reported statistically significant (p<0.01) improvements in their QOL, and more than one-half (51.2%) had a favorable adherence score of >80%. Qualitative feedback identified specific challenges to adherence and recognition of program success in symptom management.Conclusions: Our study demonstrated the value of community-based podoconiosis programming in improving the lives of patients. Practices such as regular feet washing, emollient application, shoe wearing and limb raising can result in a marked reduction of morbidity. Our findings support the argument for scaling up these management practices across Rwanda.","PeriodicalId":23218,"journal":{"name":"Transactions of The Royal Society of Tropical Medicine and Hygiene","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140094626","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}

With the coronavirus disease 2019 (COVID-19) pandemic, several control strategies were suspended, probably compromising the goals of eradicating the disease in the country. We aimed to assess the impact of the COVID-19 pandemic on Schistosomiasis Control Program (PCE) actions in all endemic states of Brazil.Methods: We performed an ecological study using spatial analysis techniques. The PCE variables assessed were the population surveyed, the number of Kato-Katz tests, positive cases of schistosomiasis and the percentage of cases treated between 2015 and 2021. The percent change was calculated to verify if there was an increase or decrease in 2020 and 2021, along with time trend analyses provided by the Joinpoint model. Spatial distribution maps were elaborated considering the percent change.Results: The surveyed population decreased in 2020 (-65.38%) and 2021 (-37.94%) across Brazil. There was a proportional reduction in the number of Kato-Katz tests (2020, -67.48%; 2021, -40.52%), a decrease in the percentage of positive cases (2020, -71.16%; 2021, -40.5%) and a reduction in the percentage of treated cases (2020, -72.09%; 2021, -41.67%).

Also, COVID-19-positive participants exhibited more prolonged partial thromboplastin time and lower D-dimer levels than those of COVID-19-negative subjects (p<0.05). The study also revealed gender-dependent impacts on platelet counts, implying a possible relationship with the greater infection mortality rate in men than in women (p<0.001). In addition, the study found a link between changes in coagulation test results and death in COVID-19 patients (p<0.001). The evidence regarding the effects of COVID-19 on blood cell counts and coagulation, on the other hand, is conflicting, most likely due to variances in study populations and the timing of testing postinfection.Conclusions: According to the findings, COVID-19-related alterations in blood cell count and clotting ability may be risk factors for death.","PeriodicalId":23218,"journal":{"name":"Transactions of The Royal Society of Tropical Medicine and Hygiene","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141856567","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}

We then performed country-level regressions in the global sample and explored heterogeneity across World Bank development groups.Results: Globally, higher trust in institutions significantly increased vaccination rates (p<0.01) and vaccination speed (p<0.01).

Of the 92 cities, 22 were human endemic areas. The state had a low incidence level (0.6 per 100 000). Lethality was higher compared with the Brazilian average. More than 90% of infections occurred in urban areas. Most cases (66%) occurred in men. The predominant age groups were 0-4 y (28.7%) and 20-39 y (32.9%).

Despite 10-15 rounds of mass drug administration (MDA) in India, the global LF elimination target of 2030 appears challenging.

Through the motivation-opportunity-ability-behaviour (MOAB) lens, we systematically reviewed the facilitators and barriers encountered in LF elimination in India. We followed Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. We searched PubMed, Embase, ProQuest and Google Scholar databases to explore factors related to MDA program implementation in India through 30 June 2021. We analysed the data using a thematic framework. We identified 576 studies; of these, 20 studies were included. This review revealed that the public health system for distributing MDA drugs in India created a better enabling environment, including zero out-of-pocket expenditure, door-step distribution of medicines and ample capacity-building training and follow-up. However, community members were unaware of the rationale for drug consumption, leading to a gap in drug distribution and consumption. Motivation is required among community members, which suggests capacity-building training for service providers to counsel the community.","PeriodicalId":23218,"journal":{"name":"Transactions of The Royal Society of Tropical Medicine and Hygiene","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140176662","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}
