Abstract

Abstract Background Mass drug administration (MDA) and indoor residual spraying (IRS) are potent malaria burden reduction tools. The impact of combining MDA and IRS is not well documented. We evaluated the impact of MDA + IRS compared to IRS alone at a high transmission site in Eastern Uganda. Methods A quasi-experimental study was implemented in Toroma and Kapujan subcounties in north eastern Uganda. Both subcounties received four rounds of IRS using primiphos-methyl (Acttellic SC300) 6–8 months apart from December 2016 to December 2018. Eligible residents of Kapujan simultaneously received MDA using dihydroartemesinin-piperaquine (DHA-PQ). Health facility data was used to monitor malaria case incidence rate and test positivity rates. Results In the MDA + IRS arm, malaria incidence dropped by 83% (IRR: 0·17 (0.16–0.18); p

Abstract

Introduction: Distribution of HIV self-testing (HIVST) kits through MSM peer networks is a novel and effective strategy to increase HIV testing coverage in this high-risk population. No study has evaluated the cost or cost effectiveness of peer distribution of HIVST strategies among MSM in sub-Saharan Africa. Methods: From June to August 2018, we conducted a pilot study of secondary MSM peer HIVST kit distribution at The AIDS Support Organization at Entebbe and Masaka. We used an ingredients approach to estimate the cost of MSM peer HIVST kit distribution relative to standard-of-care (SOC) hotspot testing using programme expenditure data reported in US dollars. The provider perspective was used to estimate incremental cost-effective ratios per HIV infection averted using the difference in HIV annual transmission rates between MSM with HIV who knew their status and were not virologically suppressed and MSM with HIV who did not know their status. Results: We enrolled 297 participants of whom 150 received MSM peer HIVST kit distribution (intervention group) and 147 received TASO standard of care HIV testing (control group). Provider cost for the intervention was $2,276 compared with $1,827 for SOC during the 3-month study period. Overall, the intervention resulted in higher HIV positivity yield (4.9 vs. 1.4%) and averted more HIV infections per quarter (0.364 vs. 0.104) compared with SOC. The cost per person tested was higher for the intervention compared to SOC ($15.90 vs. $12.40). Importantly, the cost per new HIV diagnosis ($325 vs. $914) and cost per transmission averted ($6,253 vs. $ 17,567) were lower for the intervention approach relative to SOC. The incremental cost per HIV transmission averted by the self-testing program was $1,727. The incremental cost to providers per additional HIV-positive person identified by the intervention was $147.30. Conclusion: The intervention strategy was cost-effective, and identified more undiagnosed HIV infections than SOC hotspot testing at a cost-effectiveness threshold of US $2,129. Secondary distribution of HIVST kits through peers should further be evaluated with longer duration aimed at diagnosing 95% of all persons with HIV by 2030; the first UNAIDS 95-95-95 target.

Abstract

In this paper, we discuss challenges associated with implementing a policy for Ancillary Care (AC) for related and unrelated (serious) adverse events during an Ebola vaccine trial conducted in a remote area of the Democratic Republic of the Congo. Conducting clinical trials in resourceconstrained settings can raise context-related challenges that have implications for study participants' health and wellbeing. During the Ebola vaccine study, three participants were injured in road traffic accidents, but there were unexpected difficulties when trying to apply the AC policy. First, because of the nature of the adverse events, the insurer refused to cover the costs. Second, the AC policy did not address treatments by traditional medicine, even though traditional medicines are frequently used and highly trusted in the study community. This highlighted a contrast between the researchers' well-intentioned AC approach and the participants' legitimate preferences. The way in which researchers should address their responsibility to provide AC is not straightforward; it requires contextualization. Our experience highlights the importance of involving community representatives and the local ethics committee to ensure development of an AC policy that is culturally and ethically appropriate. Additionally, the insurance contract should clearly stipulate which adverse events are linked to the trial participation, and thus eligible for coverage, to avoid controversies when claims are made.

Abstract

Objective: We aimed to synthesise available evidence on the effects of community-based interventions in improving various dietary outcome measures. Design: Systematic review and meta-analysis. Setting: We searched databases including Medline, EMBASE, PSYCINFO, CINAHL and the Cochrane registry for studies reported between January 2000 and June 2022. The methodological quality of the included studies was evaluated using the Cochrane risk of bias tools for each study type. For some of the outcomes, we pooled the effect size using a random-effects meta-analysis. Participants: A total of fifty-one studies, thirty-three randomised and eighteen non-randomised, involving 100 746 participants were included. Results: Overall, thirty-seven studies found a statistically significant difference in at least one dietary outcome measure favouring the intervention group, whereas fourteen studies found no statistically significant difference. Our meta-analyses indicated that, compared with controls, interventions were effective in decreasing daily energy intake (MJ/d) (mean difference (MD): –0·25; 95 % CI: –0·37, –0·14), fat % of energy (MD: –1·01; 95 % CI: –1·76, –0·25) and saturated fat % of energy (MD: –1·54; 95 % CI: –2·01, –1·07). Furthermore, the interventions were effective in improving fibre intake (g/d) (MD: 1·08; 95 % CI: 0·39, 1·77). Effective interventions use various strategies including tailored individual lifestyle coaching, health education, health promotion activities, community engagement activities and/or structural changes. Conclusion: This review shows the potential of improving dietary patterns through community-based CVD preventive interventions. Thus, development and implementation of context-specific preventive interventions could help to minimise dietary risk factors, which in turn decrease morbidity and mortality due to CVD and other non-communicable diseases.
