\"\"When you educate a girl, you educate a nation. --Malawian saying. The women of Malawi, like many other women in developing countries, struggle to find their way out of poverty and build a better life for themselves and their families. Weaving a Malawi Sunrise tells the story of Memory Chazeza's quest to get an education and to build a school for young women. Roberta Laurie was one of many who helped Memory realize her vision of seeing young girls become strong and independent women who could care for themselves and their future families. During her time in Malawi, Laurie met several other women, each of whom had a story of her own. Laurie interweaves these accounts with well-researched information about the country's underlying social and political context. Readers interested in Africa, global affairs, women's studies, development, and international education will give high marks to Weaving a Malawi Sunrise.\"-- Provided by publisher.

The coronavirus disease (COVID-19) pandemic might affect tuberculosis (TB) diagnosis and patient care. We analyzed a citywide electronic TB register in Blantyre, Malawi and interviewed TB officers. Malawi did not have an official COVID-19 lockdown but closed schools and borders on March 23, 2020. In an interrupted time series analysis, we noted an immediate 35.9% reduction in TB notifications in April 2020; notifications recovered to near prepandemic numbers by December 2020. However, 333 fewer cumulative TB notifications were received than anticipated. Women and girls were affected more (30.7% fewer cases) than men and boys (20.9% fewer cases). Fear of COVID-19 infection, temporary facility closures, inadequate personal protective equipment, and COVID-19 stigma because of similar symptoms to TB were mentioned as reasons for fewer people being diagnosed with TB. Public health measures could benefit control of both TB and COVID-19, but only if TB diagnostic services remain accessible and are considered safe to attend.

Childhood mortality remains high in sub-Saharan Africa. In this cluster-randomized, placebo-controlled trial, mortality among children younger than 5 years of age was lower among those who received azithromycin than among those who received placebo.

WHO estimates exposure to air pollution from cooking with solid fuels is associated with over 4 million premature deaths worldwide every year including half a million children under the age of 5 years from pneumonia. We hypothesised that replacing open fires with cleaner burning biomass-fuelled cookstoves would reduce pneumonia incidence in young children. We did a community-level open cluster randomised controlled trial to compare the effects of a cleaner burning biomass-fuelled cookstove intervention to continuation of open fire cooking on pneumonia in children living in two rural districts, Chikhwawa and Karonga, of Malawi. Clusters were randomly allocated to intervention and control groups using a computer-generated randomisation schedule with stratification by site, distance from health centre, and size of cluster. Within clusters, households with a child under the age of 4·5 years were eligible. Intervention households received two biomass-fuelled cookstoves and a solar panel. The primary outcome was WHO Integrated Management of Childhood Illness (IMCI)-defined pneumonia episodes in children under 5 years of age. Efficacy and safety analyses were by intention to treat. The trial is registered with ISRCTN, number ISRCTN59448623. We enrolled 10 750 children from 8626 households across 150 clusters between Dec 9, 2013, and Feb 28, 2016. 10 543 children from 8470 households contributed 15 991 child-years of follow-up data to the intention-to-treat analysis. The IMCI pneumonia incidence rate in the intervention group was 15·76 (95% CI 14·89–16·63) per 100 child-years and in the control group 15·58 (95% CI 14·72–16·45) per 100 child-years, with an intervention versus control incidence rate ratio (IRR) of 1·01 (95% CI 0·91–1·13; p=0·80). Cooking-related serious adverse events (burns) were seen in 19 children; nine in the intervention and ten (one death) in the control group (IRR 0·91 [95% CI 0·37–2·23]; p=0·83). We found no evidence that an intervention comprising cleaner burning biomass-fuelled cookstoves reduced the risk of pneumonia in young children in rural Malawi. Effective strategies to reduce the adverse health effects of household air pollution are needed. Medical Research Council, UK Department for International Development, and Wellcome Trust.

Lack of education and an economic dependence on men are often suggested as important risk factors for HIV infection in women. We assessed the efficacy of a cash transfer programme to reduce the risk of sexually transmitted infections in young women. In this cluster randomised trial, never-married women aged 13–22 years were recruited from 176 enumeration areas in the Zomba district of Malawi and randomly assigned with computer-generated random numbers by enumeration area (1:1) to receive cash payments (intervention group) or nothing (control group). Intervention enumeration areas were further randomly assigned with computer-generated random numbers to conditional (school attendance required to receive payment) and unconditional (no requirements to receive payment) groups. Participants in both intervention groups were randomly assigned by a lottery to receive monthly payments ranging from US$1 to $5, while their parents were independently assigned with computer-generated random numbers to receive $4–10. Behavioural risk assessments were done at baseline and 12 months; serology was tested at 18 months. Participants were not masked to treatment status but counsellors doing the serologic testing were. The primary outcomes were prevalence of HIV and herpes simplex virus 2 (HSV-2) at 18 months and were assessed by intention-to-treat analyses. The trial is registered, number NCT01333826. 88 enumeration areas were assigned to receive the intervention and 88 as controls. For the 1289 individuals enrolled in school at baseline with complete interview and biomarker data, weighted HIV prevalence at 18 month follow-up was 1·2% (seven of 490 participants) in the combined intervention group versus 3·0% (17 of 799 participants) in the control group (adjusted odds ratio [OR] 0·36, 95% CI 0·14–0·91); weighted HSV-2 prevalence was 0·7% (five of 488 participants) versus 3·0% (27 of 796 participants; adjusted OR 0·24, 0·09–0·65). In the intervention group, we noted no difference between conditional versus unconditional intervention groups for weighted HIV prevalence (3/235 [1%] vs 4/255 [2%]) or weighted HSV-2 prevalence (4/233 [1%] vs 1/255 [<1%]). For individuals who had already dropped out of school at baseline, we detected no significant difference between intervention and control groups for weighted HIV prevalence (23/210 [10%] vs 17/207 [8%]) or weighted HSV-2 prevalence (17/211 [8%] vs 17/208 [8%]). Cash transfer programmes can reduce HIV and HSV-2 infections in adolescent schoolgirls in low-income settings. Structural interventions that do not directly target sexual behaviour change can be important components of HIV prevention strategies.

The RTS,S/AS01E malaria vaccine (RTS,S) was introduced by national immunisation programmes in Ghana, Kenya, and Malawi in 2019 in large-scale pilot schemes. We aimed to address questions about feasibility and impact, and to assess safety signals that had been observed in the phase 3 trial that included an excess of meningitis and cerebral malaria cases in RTS,S recipients, and the possibility of an excess of deaths among girls who received RTS,S than in controls, to inform decisions about wider use. In this prospective evaluation, 158 geographical clusters (66 districts in Ghana; 46 sub-counties in Kenya; and 46 groups of immunisation clinic catchment areas in Malawi) were randomly assigned to early or delayed introduction of RTS,S, with three doses to be administered between the ages of 5 months and 9 months and a fourth dose at the age of approximately 2 years. Primary outcomes of the evaluation, planned over 4 years, were mortality from all causes except injury (impact), hospital admission with severe malaria (impact), hospital admission with meningitis or cerebral malaria (safety), deaths in girls compared with boys (safety), and vaccination coverage (feasibility). Mortality was monitored in children aged 1–59 months throughout the pilot areas. Surveillance for meningitis and severe malaria was established in eight sentinel hospitals in Ghana, six in Kenya, and four in Malawi. Vaccine uptake was measured in surveys of children aged 12–23 months about 18 months after vaccine introduction. We estimated that sufficient data would have accrued after 24 months to evaluate each of the safety signals and the impact on severe malaria in a pooled analysis of the data from the three countries. We estimated incidence rate ratios (IRRs) by comparing the ratio of the number of events in children age-eligible to have received at least one dose of the vaccine (for safety outcomes), or age-eligible to have received three doses (for impact outcomes), to that in non-eligible age groups in implementation areas with the equivalent ratio in comparison areas. To establish whether there was evidence of a difference between girls and boys in the vaccine's impact on mortality, the female-to-male mortality ratio in age groups eligible to receive the vaccine (relative to the ratio in non-eligible children) was compared between implementation and comparison areas. Preliminary findings contributed to WHO's recommendation in 2021 for widespread use of RTS,S in areas of moderate-to-high malaria transmission. By April 30, 2021, 652 673 children had received at least one dose of RTS,S and 494 745 children had received three doses. Coverage of the first dose was 76% in Ghana, 79% in Kenya, and 73% in Malawi, and coverage of the third dose was 66% in Ghana, 62% in Kenya, and 62% in Malawi. 26 285 children aged 1–59 months were admitted to sentinel hospitals and 13 198 deaths were reported through mortality surveillance. Among children eligible to have received at least one dose of RTS,S, there was no evidence of an excess of meningitis or cerebral malaria cases in implementation areas compared with comparison areas (hospital admission with meningitis: IRR 0·63 [95% CI 0·22–1·79]; hospital admission with cerebral malaria: IRR 1·03 [95% CI 0·61–1·74]). The impact of RTS,S introduction on mortality was similar for girls and boys (relative mortality ratio 1·03 [95% CI 0·88–1·21]). Among children eligible for three vaccine doses, RTS,S introduction was associated with a 32% reduction (95% CI 5–51%) in hospital admission with severe malaria, and a 9% reduction (95% CI 0–18%) in all-cause mortality (excluding injury). In the first 2 years of implementation of RTS,S, the three primary doses were effectively deployed through national immunisation programmes. There was no evidence of the safety signals that had been observed in the phase 3 trial, and introduction of the vaccine was associated with substantial reductions in hospital admission with severe malaria. Evaluation continues to assess the impact of four doses of RTS,S. Gavi, the Vaccine Alliance; the Global Fund to Fight AIDS, Tuberculosis and Malaria; and Unitaid.

Kwashiorkor, an enigmatic form of severe acute malnutrition, is the consequence of inadequate nutrient intake plus additional environmental insults. To investigate the role of the gut microbiome, we studied 317 Malawian twin pairs during the first 3 years of life. During this time, half of the twin pairs remained well nourished, whereas 43% became discordant, and 7% manifested concordance for acute malnutrition. Both children in twin pairs discordant for kwashiorkor were treated with a peanut-based, ready-to-use therapeutic food (RUTF). Time-series metagenomic studies revealed that RUTF produced a transient maturation of metabolic functions in kwashiorkor gut microbiomes that regressed when administration of RUTF was stopped. Previously frozen fecal communities from several discordant pairs were each transplanted into gnotobiotic mice. The combination of Malawian diet and kwashiorkor microbiome produced marked weight loss in recipient mice, accompanied by perturbations in amino acid, carbohydrate, and intermediary metabolism that were only transiently ameliorated with RUTF. These findings implicate the gut microbiome as a causal factor in kwashiorkor.

Household contact tracing provides TB screening and TB preventive therapy (TPT) to contacts at high risk of TB disease. However, it is resource intensive, inconvenient, and often poorly implemented. We investigated a novel model aiming to improve uptake. Between May and December 2014, we randomised patient with TB who consented to participate in the trial to either standard of care (SOC) or intervention (PACTS) arms. Participants randomised to PACTS received one screening/triage tool (adapted from WHO integrated management of adolescent and adult illnesses [IMAI] guidelines) and sputum pots for each reported household contact. The tool guided participants through symptom screening; TPT (6-months of isoniazid) eligibility; and sputum collection for contacts. Patients randomised to SOC were managed in accordance with national guidelines, that is, they received verbal instruction on who to bring to clinics for investigation using national guidelines. The primary outcome was the proportion of adult contacts receiving treatment for TB within 3 months of randomisation. Secondary outcomes were the proportions of child contacts under age 5 years (U5Y) who were commenced on, and completed, TPT. Data were analyzed by logistic regression with random effects to adjust for household clustering. Two hundred and fourteen index TB participants were block-randomized from two sites (107 PACTS, reporting 418 contacts; and 107 SOC, reporting 420 contacts). Overall, 62.8% of index TB participants were HIV-positive and 52.1% were TB culture-positive. 250 otherwise eligible TB patients declined participation and 6 households (10 PACTS, 6 SOC) were lost to follow-up and were not included in the analysis. By three months, nine contacts (PACTS: 6, [1.4%]; SOC: 3, [0.7%]) had TB diagnosed, with no difference between groups (adjusted odds ratio [aOR]: 2.18, 95% CI: 0.60-7.95). Eligible PACTS contacts (37/96, 38.5%) were more likely to initiate TPT by 3-months compared to SOC contacts (27/101, 26.7%; aOR 2.27, 95% CI: 1.04-4.98). U5Y children in the PACTS arm (47/81 58.0%) were more likely to have initiated TPT before the 3-month visit compared to SOC children (36/89, 41.4%; aOR: 2.31, 95% CI: 1.05-5.06). A household-centred patient-delivered symptom screen and IPT eligibility assessment significantly increased timely TPT uptake among U5Y children, but did not significantly increase TB diagnosis. This model needs to be optimized for acceptability, given low participation, and investigated in other low resource settings.

In many sub-Saharan African countries, it is recommended that children with sickle cell anaemia receive malaria chemoprevention with monthly sulfadoxine–pyrimethamine or daily proguanil as the standard of care. However, the efficacy of these interventions is compromised by high-grade antifolate resistance of Plasmodium falciparum and poor adherence. We aimed to compare the efficacy of weekly dihydroartemisinin–piperaquine and monthly sulfadoxine–pyrimethamine for the prevention of clinical malaria in children with sickle cell anaemia in areas with high-grade sulfadoxine–pyrimethamine resistance of P falciparum in Uganda and Malawi. We did an individually randomised, parallel group, double-blind, placebo-controlled trial at two hospitals in Uganda and two hospitals in Malawi. Children (aged 6 months to 15 years) with sickle cell anaemia with a bodyweight of at least 5kg were randomly assigned (1:1) by computer-generated block randomisation, stratified by site and weight category, to receive either weekly dihydroartemisinin–piperaquine (approximately 2·5 mg per kg bodyweight dihydroartemisinin and 20 mg per kg bodyweight per day piperaquine) or monthly sulfadoxine–pyrimethamine (approximately 25 mg per kg bodyweight sulfadoxine and 1·25 mg per kg bodyweight). Placebos matching the alternative treatment were used in each treatment group to maintain masking of the different dosing schedules from the participants and caregivers, study staff, investigators, and data analysts. All children younger than 5 years received penicillin twice daily as standard of care. The primary endpoint was the incidence of clinical malaria, defined as a history of fever in the preceding 48 h or documented axillary temperature of 37·5°C or higher plus the detection of P falciparum parasites on microscopy (any parasite density). Secondary efficacy outcomes were any malaria parasitaemia (on either microscopy or malaria rapid diagnostic test), all-cause unscheduled clinic visits, all-cause and malaria-specific hospitalisation, sickle cell anaemia-related events (including vaso-occlusive crises, acute chest syndrome, stroke), need for blood transfusion, and death. All primary and secondary outcomes were assessed in the modified intention-to-treat population, which included all participants who were randomly assigned for whom endpoint data were available. Safety was assessed in in all children who received at least one dose of the study drug. Complete case analysis was conducted using negative-binomial regression. This study was registered with Clinicaltrials.gov, NCT04844099. Between April 17, 2021, and May 30, 2022, 725 participants were randomly assigned; of whom 724 were included in the primary analysis (367 participants in the dihydroartemisinin–piperaquine group and 357 participants in the sulfadoxine–pyrimethamine group). The median follow-up time was 14·7 months (IQR 11·2–18·2). The incidence of clinical malaria was 8·8 cases per 100 person-years in the dihydroartemisinin–piperaquine group and 43.7 events per 100 person-years in the sulfadoxine–pyrimethamine group (incidence rate ratio [IRR] 0·20 [95% CI 0·14–0·30], p<0·0001). The incidence of hospitalisation with any malaria was lower in the dihydroartemisinin–piperaquine group than the sulfadoxine–pyrimethamine group (10·4 vs 37·0 events per 100 person-years; IRR 0·29 [0·20–0·42], p<0·0001) and the number of blood transfusions was also lower in the dihydroartemisinin–piperaquine group than the sulfadoxine–pyrimethamine group (52·1 vs 72·5 events per 100 person-years; IRR 0·70 [0·54–0·90], p=0·006). The incidence of all-cause unscheduled clinic visits and all-cause hospitalisations were similar between the two groups, however, participants in the dihydroartemisinin–piperaquine group had more clinic visits unrelated to malaria (IRR 1·12 [1·00–1·24], p=0·042) and more hospitalisations with lower respiratory tract events (16·5 vs 8·5 events per 100 person-years; IRR 1·99 [1·25–3·16], p=0·0036) than participants in the sulfadoxine–pyrimethamine group. The number of serious adverse events in the dihydroartemisinin–piperaquine group was similar to that in the sulfadoxine–pyrimethamine group (vaso-occlusive crisis [154 of 367 participants dihydroartemisinin–piperaquine group vs 132 of 357 participants in the sulfadoxine–pyrimethamine group] and suspected sepsis [115 participants vs 92 participants]), with the exception of acute chest syndrome or pneumonia (51 participants vs 32 participants). The number of deaths were similar between groups (six [2%] of 367 participants in the dihydroartemisinin–piperaquine group and eight (2%) of 357 participants in the sulfadoxine–pyrimethamine group). Malaria chemoprophylaxis with weekly dihydroartemisinin–piperaquine in children with sickle cell anaemia is safe and considerably more efficacious than monthly sulfadoxine–pyrimethamine. However, monthly sulfadoxine–pyrimethamine was associated with fewer episodes of non-malaria-related illnesses, especially in children 5 years or older not receiving penicillin prophylaxis, which might reflect its antimicrobial effects. In areas with high P falciparum antifolate resistance, dihydroartemisinin–piperaquine should be considered as an alternative to sulfadoxine–pyrimethamine for malaria chemoprevention in children younger than 5 years with sickle cell anaemia receiving penicillin-V prophylaxis. However, there is need for further studies in children older than 5 years. Research Council of Norway and UK Medical Research Council.

Soil-transmitted helminths are targeted for elimination as a public health problem. This study assessed whether, with high coverage, community-wide mass drug administration (MDA) could lead to transmission interruption. DeWorm3 is an open-label, community cluster-randomised controlled trial in Benin, India, and Malawi. In each country, a single governmental administrative unit (population ≥80 000 individuals) with soil-transmitted helminth endemicity and participation in at least five rounds of community-wide MDA for lymphatic filariasis, was divided into 40 clusters (population ≥1650 individuals), which were randomly assigned (1:1) to community-wide MDA versus school-based deworming. Laboratory personnel were masked to exposure status and all investigators were masked to post-baseline outcome data until unmasking. In all clusters, preschool-aged and school-aged children received school-based deworming as per national guidelines for 3 years. In intervention clusters, door-to-door community-wide MDA (a single oral dose of 400 mg albendazole) was delivered to all eligible individuals biannually by community drug distributors for 3 years. All individuals aged 12 months and older in India and Benin and aged 24 months and older in Malawi were eligible for treatment, except women in the first trimester of pregnancy, those with adverse reactions to benzimidazoles, those who were acutely ill or intoxicated, or those reporting treatment within the previous 2 weeks. The co-primary outcomes were individual-level prevalence and cluster-level transmission interruption (ie, weighted prevalence of predominant species of ≤2%) of the predominant soil-transmitted helminth species, assessed by quantitative PCR (qPCR) 24 months after the last round of MDA. The analysis set contained a subset of randomly selected participants per cluster who enrolled in the endline assessment, provided a stool sample, and had a qPCR result. All individuals who received treatment were eligible for inclusion in the safety population. This trial is registered with ClinicalTrials.gov (NCT03014167), and is active but not recruiting. Between Oct 10, 2017, and Feb 17, 2023, 120 clusters (40 clusters per country, comprising 357 716 individuals) were randomly assigned, 60 to community-wide MDA and 60 to school-based deworming. 184 030 (51·4%) individuals in the clusters at baseline were female, 173 663 (48·5%) were male, and 23 (<0·1%) were other. The analysis set consisted of 58 827 individuals in the control group and 58 554 in the intervention group 24 months after the cessation of all deworming, Necator americanus prevalence (the predominant species at all sites) in the community-wide MDA group was lower than the school-based deworming group in Benin (adjusted prevalence ratio [aPR] 0·44 [95% CI 0·34–0·58]), India (0·41 [0·32–0·52]), and Malawi (0·40 [0·34–0·46]). Transmission interruption was achieved for N americanus in 11 (55%) of 20 intervention clusters versus six (30%) of 20 control clusters in Benin (p=0·20), in one (5%) intervention cluster versus no control clusters in India (p=1·00), and in no clusters in either group in Malawi (p=1·00). 984 adverse events were reported among 487 participants over the study, of which 32 among 13 participants resulted in hospitalisation and were classified as serious adverse events (three of which were related to study procedures). Soil-transmitted helminth transmission interruption might be possible in focal geographies but does not appear to be programmatically feasible within the evaluated timeframe. Community-wide MDA should be considered as an alternative strategy to school-based deworming programmes to improve equity and outcomes in helminth-endemic areas. The Gates Foundation.
