    Background. Dyspepsia has been demonstrated worldwide to have major personal and societal  impacts, but data on the burden of this disease in Africa are lacking.Objective. To document the prevalence of dyspepsia and its quality-of-life impact among healthcare  workers (HCWs) at Butare University Teaching Hospital (BUTH), Rwanda.Methods. A cross-sectional survey among consenting HCWs at BUTH was conducted. Multilingual  interviewers guided participants through validated questionnaires, including the Short-Form Leeds Dyspepsia Questionnaire (SF-LDQ), to detect the presence and frequency of dyspeptic symptoms, and the Short-Form Nepean Dyspepsia Index (SF-NDI), to examine the impact of dyspepsia on quality of life.Results. The study included 378 enrolled HCWs, all of whom provided responses to the SF-LDQ and 356 of whom responded to the SF-NDI. The prevalence of dyspepsia in the study population was 38.9% (147/378). Of these 147 HCWs, 79 (53.7%) had very mild dyspepsia, 33 (22.4%) had mild dyspepsia, 20 (13.6%) had moderate dyspepsia and 15 (10.2%) had severe dyspepsia. Females were more likely to complain of dyspepsia than males (98/206 v. 49/172; odds ratio (OR) 2.3; 95% confidence interval (CI) 1.5 - 3.5; p<0.001). Participants with dyspepsia of at least mild severity had SF-NDI scores reflecting reduced quality of life when compared with non-dyspeptic participants (OR 17.0; 95% CI 5.0 - 57.1; p<0.001), with most marked effects on the ‘tension’ and ‘eating and drinking’ subdomains of theSF-NDI.Conclusion. The prevalence of dyspepsia among HCWs in Rwanda is high and is associated with lowered quality of life

    Contains fulltext : 162707.pdf (publisher's version ) (Open Access)BACKGROUND: Universal long-lasting insecticidal net (LLIN) coverage (ULC) has reduced malaria morbidity and mortality across Africa. Although information is available on bed net use in specific groups, such as pregnant women and children under 5 years, there is paucity of data on their use among the general population. Bed net source, ownership and determinants of use among individuals from households in an eastern Rwanda community 8 months after a ULC were characterized. METHODS: Using household-based, interviewer-administered questionnaires and interviewer-direct observations, data on bed net source, ownership and key determinants of net use, including demographics, socio-economic status indicators, house structure characteristics, as well as of bed net quantity, type and integrity, were collected from 1400 randomly selected households. Univariate and mixed effects logistic regression modelling was done to assess for determinants of bed net use. RESULTS: A total of 1410 households and 6598 individuals were included in the study. Overall, the proportion of households with at least one net was 92 % while bed net usage was reported among 72 % of household members. Of the households surveyed, a total ownership of 2768 nets was reported, of which about 96 % were reportedly LLINs received from the ULC. By interviewer-physical observation, 88 % of the nets owned were of the LLIN type with the remaining 12 % did not carry any mark to enable type recognition. The odds of bed net use were significantly lower among males and individuals: from households of low socio-economic status, from households with /=two sleeping spaces, and those reporting to have not slept on a bed. CONCLUSION: In this study, despite high a bed net coverage, over 25 % of members reported not to have slept under a bed net the night before the survey. Males were particularly less likely to use bed nets even where nets were available. Household socio-economic status, number of bed nets and type and number of sleeping spaces were key determinants of bed net use. To maximize impact of ULC, strategies that target males as well as those that ensure ITN coverage for all, address barriers to feasible and convenient bed net use including covering over all sleeping space types, and provide net hanging supports, are needed.10 p

    Community mobilization for malaria elimination: application of an open space methodology in Ruhuha sector, Rwanda

    Background Despite the significant reduction of malaria transmission in Rwanda, Ruhuha sector is still a highly endemic area for malaria. The objective of this activity was to explore and brainstorm the potential roles of various community stakeholders in malaria elimination. Methods Horizontal participatory approaches such as ‘open space’ have been deployed to explore local priorities, stimulate community contribution to project planning, and to promote local capacity to manage programmes. Two open space meetings were conducted with 62 and 82 participants in years 1 and 2, respectively. Participants included purposively selected community and local organizations’ representatives. Results Malaria was perceived as a health concern by the respondents despite the reported reduction in prevalence from 60 to 20% for cases at the local health centre. Some misconceptions of the cause of malaria and misuse of preventive strategies were noted. Poverty was deemed to be a contributing factor to malaria transmission, with suggestions that improvement of living conditions for poor families might help malaria reduction. Participants expressed willingness to contribute to malaria elimination and underscored the need for constant education, sensitization and mobilization towards malaria control in general. Active diagnosis, preventative strategies and prompt treatment of malaria cases were all mentioned by participants as ways to reduce malaria. Participants suggested that partnership of stakeholders at various levels could speed up programme activities. A community rewards system was deemed important to motivate engaged participants, i.e., community health workers and households. Establishment of malaria clubs in schools settings was also suggested as crucial to speed up community awareness and increase skills towards further malaria reduction. Conclusions This bottom-up approach was found useful in engaging the local community, enabling them to explore issues related to malaria in the area and suggest solutions for sustainable malaria elimination gains

    Effect of trimethoprim-sulphamethoxazole on the risk of malaria in HIV-infected Ugandan children living in an area of widespread antifolate resistance

    <p>Abstract</p> <p>Background</p> <p>Daily trimethoprim-sulfamethoxazole (TS) protects against malaria, but efficacy may be diminished as anti-folate resistance increases. This study assessed the incidence of falciparum malaria and the prevalence of resistance-conferring <it>Plasmodium falciparum </it>mutations in HIV-infected children receiving daily TS and HIV-uninfected children not taking TS.</p> <p>Materials and methods</p> <p>Subjects were 292 HIV-infected and 517 uninfected children from two cohort studies in Kampala, Uganda observed from August 2006 to December 2008. Daily TS was given to HIV-infected, but not HIV-uninfected children and all participants were provided an insecticide-treated bed net. Standardized protocols were used to measure the incidence of malaria and identify markers of antifolate resistance.</p> <p>Results</p> <p>Sixty-five episodes of falciparum malaria occurred in HIV-infected and 491 episodes in uninfected children during the observation period. TS was associated with a protective efficacy of 80% (0.10 vs. 0.45 episodes per person year, p < 0.001), and efficacy did not vary over three consecutive 9.5 month periods (81%, 74%, 80% respectively, p = 0.506). The prevalences of <it>dhfr </it>51I, 108N, and 59R and <it>dhps </it>437G and 540E mutations were each over 90% among parasites infecting both HIV-infected and uninfected children. Prevalence of the <it>dhfr </it>164L mutation, which is associated with high-level resistance, was significantly higher in parasites from HIV-infected compared to uninfected children (8% vs. 1%, p = 0.001). Sequencing of the <it>dhfr </it>and <it>dhps </it>genes identified only one additional polymorphism, <it>dhps </it>581G, in 2 of 30 samples from HIV-infected and 0 of 54 samples from uninfected children.</p> <p>Conclusion</p> <p>Despite high prevalence of known anti-folate resistance-mediating mutations, TS prophylaxis was highly effective against malaria, but was associated with presence of <it>dhfr </it>164L mutation.</p
