RESUMO

BACKGROUND: Global progress on malaria control has stalled recently, partly due to challenges in universal access to malaria diagnosis and treatment. Community health workers (CHWs) can play a key role in improving access to malaria care for children under 5 years (CU5), but national policies rarely permit them to treat older individuals. We conducted a two-arm cluster randomized trial in rural Madagascar to assess the impact of expanding malaria community case management (mCCM) to all ages on health care access and use. METHODS: Thirty health centers and their associated CHWs in Farafangana District were randomized 1:1 to mCCM for all ages (intervention) or mCCM for CU5 only (control). Both arms were supported with CHW trainings on malaria case management, community sensitization on free malaria care, monthly supervision of CHWs, and reinforcement of the malaria supply chain. Cross-sectional household surveys in approximately 1600 households were conducted at baseline (Nov-Dec 2019) and endline (Nov-Dec 2021). Monthly data were collected from health center and CHW registers for 36 months (2019-2021). Intervention impact was assessed via difference-in-differences analyses for survey data and interrupted time-series analyses for health system data. RESULTS: Rates of care-seeking for fever and malaria diagnosis nearly tripled in both arms (from less than 25% to over 60%), driven mostly by increases in CHW care. Age-expanded mCCM yielded additional improvements for individuals over 5 years in the intervention arm (rate ratio for RDTs done in 6-13-year-olds, RRRDT6-13 years = 1.65; 95% CIs 1.45-1.87), but increases were significant only in health system data analyses. Age-expanded mCCM was associated with larger increases for populations living further from health centers (RRRDT6-13 years = 1.21 per km; 95% CIs 1.19-1.23). CONCLUSIONS: Expanding mCCM to all ages can improve universal access to malaria diagnosis and treatment. In addition, strengthening supply chain systems can achieve significant improvements even in the absence of age-expanded mCCM. TRIAL REGISTRATION: The trial was registered at the Pan-African Clinical Trials Registry (#PACTR202001907367187).

RESUMO

BACKGROUND: Despite the high prevalence of mental disorders and epilepsy in low- and middle-income countries, nearly 80% of patients are not treated. In Madagascar, initiatives to improve access to epilepsy and mental health care, including public awareness and training of general practitioners (GPs), were carried out between 2013 and 2018. Our study's main objective was to assess the effectiveness of these initiatives, two to five years post-intervention. METHODS: This quasi-experimental study (intervention vs. control areas) included five surveys assessing: general population's Knowledge Attitudes and Practices (KAP), GPs' KAP , number of epilepsy and mental health consultations at different levels of the healthcare system, diagnostic accuracy, and treatments' availability. OUTCOMES: In the general population, KAP scores were higher in intervention areas for epilepsy (11.4/20 vs. 10.3/20; p = 0.003). For mental disorders, regardless of the area, KAP scores were low, especially for schizophrenia (1.1/20 and 0.1/20). Among GPs, KAP scores were higher in intervention areas for schizophrenia (6.0/10 vs. 4.5/10; p = 0.008) and epilepsy (6.9/10 vs. 6.2/10; p = 0.044). Overall, there was a greater proportion of mental health and epilepsy consultations in intervention areas (4.5% vs 2.3%). Although low, concordance between GPs' and psychiatrists' diagnoses was higher in intervention areas. There was a greater variety of anti-epileptic and psychotropic medications available in intervention areas. INTERPRETATION: This research has helped to better understand the effectiveness of initiatives implemented in Madagascar to improve epilepsy and mental health care and to identify barriers which will need to be addressed. FUNDING: Sanofi Global Health, as part of the Fight Against STigma Program.

RESUMO

CONTEXT: There is a substantial lack of inter-facility referral systems for emergency obstetrical and neonatal care in rural areas of sub-Saharan Africa. Data on the costs and cost-effectiveness of such systems that reduce preventable maternal and neonatal deaths are scarce. SETTING: We aimed to determine the cost-effectiveness of a non-governmental organisation (NGO)-run inter-facility referral system for emergency obstetrical and neonatal care in rural Southern Madagascar by analysing the characteristics of cases referred through the intervention as well as its costs. DESIGN: We used secondary NGO data, drawn from an NGO's monitoring and financial administration database, including medical and financial records. OUTCOME MEASURES: We performed a descriptive and a cost-effectiveness analysis, including a one-way deterministic sensitivity analysis. RESULTS: 1172 cases were referred over a period of 4 years. The most common referral reasons were obstructed labour, ineffective labour and eclampsia. In total, 48 neonates were referred through the referral system over the study period. Estimated cost per referral was US$336 and the incremental cost-effectiveness ratio (ICER) was US$70 per additional life-year saved (undiscounted, discounted US$137). The sensitivity analysis showed that the intervention was cost-effective for all scenarios with the lowest ICER at US$99 and the highest ICER at US$205 per additional life-year saved. When extrapolated to the population living in the study area, the investment costs of the programme were US$0.13 per person and annual running costs US$0.06 per person. CONCLUSIONS: In our study, the inter-facility referral system was a very cost-effective intervention. Our findings may inform policies, decision-making and implementation strategies for emergency obstetrical and neonatal care referral systems in similar resource-constrained settings.

RESUMO

BACKGROUND: Adequate nutrition has been cited as one of the most critical components for optimal health outcomes during pregnancy. Women in Burkina Faso and Madagascar experience high rates of undernutrition due to lack of knowledge, finances, cultural norms, and autonomy. Therefore, this study aimed (1) to describe typical maternal diets during pregnancy in Burkina Faso and Madagascar, (2) to understand the multilevel factors that influence women's nutrition decision-making, and (3) to explore the extent to which women have nutrition decision-making autonomy during pregnancy. METHODS: This study was conducted between October 2020 and February 2021 in Burkina Faso and Madagascar. Semi-structured interviews, focus group interviews, and free lists were conducted among women of reproductive age and pregnant and lactating women. Textual data from interviews were recorded and translated verbatim from local languages into French. The Food Choice Process Model guided textual content analysis using Dedoose software. Free list data were analyzed using cultural domain analysis approaches. RESULTS: In Burkina Faso and Madagascar, women primarily consumed staple foods such as rice and tô during pregnancy. Participants cited eating fruits and vegetables when available, while the animal source foods were rarely consumed. Across both contexts, nutrition during pregnancy was influenced by factors that impact food choices, such as social factors, resources, ideals, and personal factors. While women and men in Madagascar had more shared decision-making on critical domains such as finances, men were the primary decision-makers in most areas of inquiry (eg, finances) in Burkina Faso. CONCLUSIONS: The lack of adequate diverse diet consumed during pregnancy is primarily due to important factors including social factors and resources. Understanding the ability for women to consume optimal diets during pregnancy is needed to target behavioral change in maternal nutrition programming.


Plain language titleA comparison of How Pregnant Women Make Decisions About What to Eat in Burkina Faso and Madagascar Using a Model Called the Food Choice Process ModelPlain language summaryHaving a proper diet is very important for the health of pregnant women. In Burkina Faso and Madagascar, many women do not get enough nutritious food due to lack of knowledge on what to eat, lack of money, cultural traditions, and not having control over their own choices. This study wants to find out (1) what women eat during pregnancy in Burkina Faso and Madagascar, (2) what influences the decisions women make about what to eat during pregnancy, and (3) explore how women had decision-making autonomy during pregnancy. The study took place in Burkina Faso and Madagascar. The researchers talked to women who could have babies and women who were already pregnant or breastfeeding. They used different methods like focus group discussions and semi-structured interviews to gather information. They recorded and translated everything that was said from the local languages to French. They used special software to analyze the information from the interviews. They also used a free list to understand the things women mentioned most often when talking about food. In Burkina Faso and Madagascar, women mostly ate basic foods like rice and tô during pregnancy. Sometimes they ate fruits and vegetables when they were available, but they did not eat much meat or other foods from animals. In both places, the women's food choices during pregnancy were influenced by different things like what their friends and family thought, how much money they had, their personal preferences, and other factors. In Madagascar, men and women made decisions together about important things like money, but in Burkina Faso, men were usually the ones making the decisions. The lack of a proper diverse diet during pregnancy in Burkina Faso and Madagascar is primarily caused by social factors and resources. To help women make better food choices during pregnancy, it's important to understand what affects their ability to have a healthy diet. This can help programs that aim to improve the nutrition of pregnant women by encouraging them to change their behavior.

RESUMO

One of the most fundamental aspects of a species' behavioral strategy is its activity budget; for primates this generally involves the allocation of available time among resting, feeding, traveling, and social behavior. Comparisons between species, populations, or individuals can reveal divergences in adaptive strategies and current stressors, and reflect responses to such diverse pressures as predation, thermoregulation, nutrition, and social needs. Further, variation across seasons is an important part of behavioral strategies to survive food scarcity; this can involve increasing or decreasing effort. We documented activity over the 24-h cycle for the cathemeral, frugivorous Eulemur fulvus and the diurnal, folivorous Propithecus diadema across 13-18 months at Tsinjoarivo, Madagascar. Their activity budgets were dominated by resting (E. fulvus: 74.1%; P. diadema: 85.2%), followed by feeding (15.8%, 12.4%), traveling (9.31%, 1.74%) and social activities (0.76%, 0.70%), respectively. The lower feeding and higher resting in P. diadema likely reflect slower gastrointestinal transit and higher reliance on microbial fermentation to extract energy from fibrous food. The two species showed opposite lean season strategies. E. fulvus increased activity, with more feeding but less travel time, consistent with a shift to less-profitable fruits, and some leaves and flowers, while increasing feeding effort to compensate ("energy maximizing"). P. diadema showed less variation across months, but the lean season still evoked reduced effort across the board (feeding, travel, and social behavior), consistent with a "time minimizing" strategy prioritizing energy conservation and microbe-assisted digestion. Understanding these divergent shifts is key to understanding natural behavior and the extent of behavioral flexibility under stressful conditions. Finally, the complex patterns of fruit availability (intra- and interannually) and the species' behavioral responses across months underscore the need to move beyond simplistic "lean/abundant season" and "fruit/leaf" dichotomies in understanding underlying energetic strategies, and species' vulnerability to habitat change.

RESUMO

INTRODUCTION: In Madagascar, the epidemiologic, therapeutic, and evolutionary aspects of multiple myeloma remain poorly understood. Our objectives were to describe the cases, report factors associated with mortality, and estimate patient survival. PATIENTS AND METHOD: This was a retrospective descriptive and analytical study conducted in five teaching hospitals in Madagascar: HJRA and CENHOSOA (Antananarivo), CHUPZAGA (Mahajanga), CHUAT (Toamasina) and CHUT (Fianarantsoa). The study included patients diagnosed with multiple myeloma between January 1, 2010 and December 31, 2021. RESULTS: Of the 11,374 cancer patients, 75 (0.66%) had multiple myeloma. The mean age of the patients was 59.9 years (±8.9) and the sex ratio was 1.5. Arterial hypertension was observed in 32% of the patients. The most common symptom of myeloma was bone pain (n = 48; 64%). Forty-six patients (61%) were diagnosed with stage III myeloma and 28 patients (37.3%) with stage IIIA myeloma according to the Durie-Salmon classification. Anemia, renal failure, hypercalcemia and fractures were present in 53%, 37%, 21% and 28% of cases, respectively. Fifty-four patients received specific treatment. The combination of melphalan-prednisone-thalidomide was used in 79.63% of cases, and one patient had received autologous stem cell transplantation. Eleven patients (14.67%) died. Chronic kidney disease (p = 0.009), smoking (p = 0.028) and two associated comorbidities (p = 0.035) were associated with mortality. The median overall survival was 45.5 months. CONCLUSION: Patient survival is shorter than reported in the literature. The high mortality rate is due to comorbidities and limited access to recommended therapies.

RESUMO

Care cascades represent the proportion of people reaching milestones in care for a disease and are widely used to track progress towards global targets for HIV and other diseases. Despite recent progress in estimating care cascades for tuberculosis (TB) disease, they have not been routinely applied at national and subnational levels, representing a lost opportunity for public health impact. As researchers who have estimated TB care cascades in high-incidence countries (India, Madagascar, Nigeria, Peru, South Africa, and Zambia), we describe the utility of care cascades and identify measurement challenges, including the lack of population-based disease burden data and electronic data capture, the under-reporting of people with TB navigating fragmented and privatised health systems, the heterogeneity of TB tests, and the lack of post-treatment follow-up. We outline an agenda for rectifying these gaps and argue that improving care cascade measurement is crucial to enhancing people-centred care and achieving the End TB goals.

RESUMO

INTRODUCTION: Malaria in pregnancy is a major driver of maternal and infant mortality in sub-Saharan Africa. The WHO recommends the administration of intermittent preventive treatment with sulfadoxine pyrimethamine (IPTp-SP) at antenatal care (ANC) visits. Despite being a highly cost-effective strategy, IPTp-SP coverage and uptake remains low. A pilot project was conducted to assess the cost-effectiveness (CE) of community-based delivery of IPTp (C-IPTp) in addition to ANC delivery to increase IPTp uptake in the Democratic Republic of Congo (DRC), Madagascar (MDG), Mozambique (MOZ) and Nigeria (NGA). METHODS: Costs and CE estimates of C-IPTp were calculated according to two scenarios: (1) costs in 'programmatic mode' (ie, costs if C-IPTp was to be implemented by national health systems) and (2) costs from the pilot project. The effectiveness of C-IPTp was obtained through estimates of the averted disability-adjusted life-years (DALYs) associated with maternal clinical malaria and anaemia, low birth weight and neonatal mortality. RESULTS: Net incremental costs of C-IPTp ranged between US$6138-US$47 177 (DRC), US$5552-US$31 552 (MDG), US$10 202-US$53 221 (MOZ) and US$667-US$28 645 (NGA) per 1000 pregnant women, under scenarios (1) and (2), respectively. Incremental cost-effectiveness ratios (ICERs) ranged between US$15-US$119 in DRC, US$9-US$53 in MDG, US$104-US$543 in MOZ and US$2-US$66 in NGA per DALY averted, under scenarios (1) and (2), respectively. ICERs fall below the WHO recommended CE threshold based on the gross domestic product per capita. CONCLUSION: Findings suggest that C-IPTp is a highly cost-effective intervention. Results can inform policy decisions on adopting and optimising effective interventions for preventing malaria in pregnancy.

RESUMO

BACKGROUND: Madagascar is among the 10 highest burden countries for malnutrition. Protein-energy malnutrition, anemia, and vitamin deficiencies are major public health problems. Hunger is exacerbated by an annual locust invasion. The current policy of large-scale government spraying of pesticides from planes is logistically complex, costly, and damaging to the environment. OBJECTIVE: Our research aimed to study the feasibility of turning the locust invasion into a protein-rich food supply for families and an economic opportunity for youth. METHODS: We conducted 20 focus group discussions (FGDs) with females and males aged 18-24 and 25 years or older and with female artisans in 6 swarm communes in Madagascar's south to understand enablers and barriers to collection, preparation, and consumption of locusts. RESULTS: Enablers include consumption by all ages in Antandroy culture and perception of locusts as a delicacy, tasty, and free. Family members have different roles in the collection and preparation of locusts. Local technologies for mass collection include digging trenches in fields and entrapment via sisal netting. Common preparations include boiling in salted water, drying, skewering, frying, and grinding locusts into flour. Disablers include pesticide contamination of locusts and the view that locusts are a famine food. CONCLUSION: Our research provided a first step in demonstrating the feasibility of transforming locust infestations into economic and nutritional opportunities in a fragile environment with high levels of poverty and malnutrition. It contributes to advocacy in Madagascar to end the use of pesticides. It responds to the government desire to address the protein-energy malnutrition burden and youth poverty in an integrated way.

RESUMO

A total of 94% of lemur species are currently threatened with extinction and more than 17 species of giant lemur are already extinct. To help prevent the extinction of Madagascar's remaining lemurs, Dr. Patricia Wright initiated conservation programs in the Ranomafana region of southern Madagascar in the 1990s. These continued and expanded, and in 2003 were consolidated with Dr. Wright's research activities when Center ValBio ("CVB") was founded in 2003. CVB believes in the "One Health" approach in understanding the relationship between humans and the environment, and one of their core principles is that effective conservation is science-based. CVB's environmental education (EE) programs (discussed herein) operate in various primary schools surrounding Ranomafana national park (RNP). The all-Malagasy team consists of long-term conservation educators as well as young intern teachers, who together address the issues of valuing lemurs and the forests that they require to survive. In this paper, we will describe three of CVB's EE programs and evaluate their impact. The primary tool used to assess impact was an analysis of pre- and post -intervention test scores evaluated using a Kruskal-Wallis test. We show that these programs (1) are popular, (2) produce concrete outputs that can change rural villages, and (3) improve local knowledge on the importance of biodiversity and sustainable development.

RESUMO

Introduction: Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2. No drug has been generally approved as safe and effective for the treatment of COVID-19. Several therapeutic agents such as COVID Organics® (CVO) have been explored as treatment options. CVO is an herbal tea composed of 62% of Artemisia annua and 38% of other plants. There is presently no existing scientific report and data on the safety and efficacy of CVO herbal drug. Thus, acute and subacute toxicity studies were undertaken to evaluate the safety and toxicity of CVO on short- and long-term usage in animal models. Materials and Methods: Phytochemical and nutritional compositions of CVO were determined using standard methods. Acute oral toxicity was investigated using female Swiss albino mice (three per group). While subacute oral toxicity was done using female and male Swiss albino rats (five per group). The animals were administered 2000 mg/kg, 5000 mg/kg, therapeutic dose; 5500 mg/kg and supratherapeutic dose; 11,000 mg/kg of CVO herbal product. The control group received water ad libitum. The oral toxicity studies were done in accordance with Organization for Economic Corporation and Development guidelines. The experimental protocol was approved by the Institutional Animal Care and Use Committee, Nigerian Institute of Medical Research (Ethics No. IRB/17/043). Results: CVO is rich in antioxidants: flavonoids (10.3%), tannins (29.1%), and phenolics (434.4 mg). It contains proteins (33.8%), carbohydrates (34.5%), fat (6.8%), and fiber (0.5%). In the acute toxicity study, no mortality was recorded in all the treated and untreated groups. The lethal dose of CVO is >5000 mg/kg body weight. The hematological, biochemical, lipid profile, and histologic parameters were all normal at therapeutic doses when compared to the control group. Conclusion: The acute and subacute oral toxicity studies revealed that CVO is not toxic. The specific organ toxicity evaluations also indicated that CVO has no toxic effects on blood parameters and vital organs structure and function at therapeutic dose. Thus, CVO is safe for short- and long-term usage. We recommend that CVO should be subjected to efficacy studies to investigate whether it is effective for COVID-19 treatment as claimed by the manufacturer.


Résumé Introduction: La maladie à coronavirus 2019 (COVID-19) est une maladie infectieuse causée par le coronavirus 2 du syndrome respiratoire aigu sévère. Aucun ne médicamenta été généralement approuvé comme étant sûr et efficace pour le traitement du COVID-19. Plusieurs agents thérapeutiques comme le COVID Organics® (CVO) ont été explorées comme options de traitement. CVO est une tisane composée à 62% d'Artemisia annua et à 38% d'autres plantes. Il y a actuellement il n'existe aucun rapport scientifique ni aucune donnée sur l'innocuité et l'efficacité du médicament à base de plantes CVO. Ainsi, des études de toxicité aiguë et subaiguë ont été entreprises évaluer la sécurité et la toxicité du CVO sur une utilisation à court et à long terme dans des modèles animaux. Matériels et méthodes: phytochimiques et les compositions nutritionnelles du CVO ont été déterminées à l'aide de méthodes standard. La toxicité orale aiguë a été étudiée chez des femmes albinos suisses souris (trois par groupe). La toxicité orale subaiguë a été réalisée sur des rats albinos suisses femelles et mâles (cinq par groupe). Les animaux étaient administrés 2 000 mg/kg, 5 000 mg/kg, 5 500 mg/kg (dose thérapeutique) et 11 000 mg/kg (dose suprathérapeutique) de produit à base de plantes CVO. Le le groupe témoin a reçu de l'eau à volonté. Les études de toxicité orale ont été réalisées conformément à l'Organisation pour la société économique et Directives de développement. Le protocole expérimental a été approuvé par le Comité institutionnel de protection et d'utilisation des animaux de l'Institut nigérian de Recherche médicale (Éthique n° IRB/17/043). Résultats: Le CVO est riche en antioxydants : flavonoïdes (10,3 %), tanins (29,1 %) et phénoliques (434,4 mg). Il contient des protéines (33,8 %), des glucides (34,5 %), des lipides (6,8 %) et des fibres (0,5 %). Dans l'étude de toxicité aiguë, aucune mortalité n'a été enregistrée chez tous les groupes traités et non traités. La dose mortelle de CVO est > 5 000 mg/kg de poids corporel. Le profil hématologique, biochimique, lipidique et les paramètres histologiques étaient tous normaux aux doses thérapeutiques par rapport au groupe témoin. Conclusion: Les conséquences orales aiguës et subaiguës des études de toxicité ont révélé que le CVO n'est pas toxique. Les évaluations de la toxicité spécifique pour certains organes ont également indiqué que le CVO n'a aucun effet toxique sur le sang. Paramètres et structure et fonction des organes vitaux à dose thérapeutique. Ainsi, CVO est sans danger pour une utilisation à court et à long terme. Nous recommandons que Le CVO doit être soumis à des études d'efficacité pour déterminer s'il est efficace pour le traitement du COVID-19, comme le prétend le fabricant.

RESUMO

Background: Immunizations are one of the most effective tools a community can use to increase overall health and decrease the burden of vaccine-preventable diseases. Nevertheless, socioeconomic status, geographical location, education, and a child's sex have been identified as contributing to inequities in vaccine uptake in low- and middle-income countries (LMICs). Madagascar follows the World Health Organization's Extended Programme on Immunization (EPI) schedule, yet vaccine distribution remains highly inequitable throughout the country. This systematic review sought to understand the differences in EPI vaccine uptake between boys and girls in Madagascar. Methods: A systematic literature search was conducted in August 2021 through MEDLINE, the Cochrane Library, Global Index Medicus, and Google Scholar to identify articles reporting sex-disaggregated vaccination rates in Malagasy children. Gray literature was also searched for relevant data. All peer-reviewed articles reporting sex-disaggregated data on childhood immunizations in Madagascar were eligible for inclusion. Risk of bias was assessed using a tool designed for use in systematic reviews. Data extraction was conducted with a pre-defined data extraction tool. Sex-disaggregated data were synthesized to understand the impact of a child's sex on vaccination status. Findings: The systematic search identified 585 articles of which a total of three studies were included in the final data synthesis. One additional publication was included from the gray literature search. Data from included articles were heterogeneous and, overall, indicated similar vaccination rates in boys and girls. Three of the four articles reported slightly higher vaccination rates in girls than in boys. A meta-analysis was not conducted due to the heterogeneity of included data. Six additional barriers to immunization were identified: socioeconomic status, mother's education, geographic location, supply chain issues, father's education, number of children in the household, and media access. Interpretation: The systematic review revealed the scarcity of available sex-stratified immunization data for Malagasy children. The evidence available was limited and heterogeneous, preventing researchers from conclusively confirming or denying differences in vaccine uptake based on sex. The low vaccination rates and additional barriers identified here indicate a need for increased focus on addressing the specific obstacles to vaccination in Madagascar. A more comprehensive assessment of sex-disaggregated vaccination status of Malagasy children and its relationship with such additional obstacles is recommended. Further investigation of potential differences in vaccination status will allow for the effective implementation of strategies to expand vaccine coverage in Madagascar equitably. Funding and registration: AH, BT, FM, GN, and RR are supported by a grant from the Bill and Melinda Gates Foundation (grant number: OPP1205877). The review protocol is registered in the Prospective Register of Systematic Reviews (PROSPERO ID: CRD42021265000).

RESUMO

BACKGROUND: Malaria remains a leading cause of morbidity and mortality worldwide, with progress in malaria control stalling in recent years. Proactive community case management (pro-CCM) has been shown to increase access to diagnosis and treatment and reduce malaria burden. However, lack of experimental evidence may hinder the wider adoption of this intervention. We conducted a cluster randomized community intervention trial to assess the efficacy of pro-CCM at decreasing malaria prevalence in rural endemic areas of Madagascar. METHODS: Twenty-two fokontany (smallest administrative unit) of the Mananjary district in southeast Madagascar were selected and randomized 1:1 to pro-CCM (intervention) or conventional integrated community case management (iCCM). Residents of all ages in the intervention arm were visited by a community health worker every 2 weeks from March to October 2017 and screened for fever; those with fever were tested by a rapid diagnostic test (RDT) and treated if positive. Malaria prevalence was assessed using RDTs on all consenting study area residents prior to and following the intervention. Hemoglobin was measured among women of reproductive age. Intervention impact was assessed via difference-in-differences analyses using logistic regressions in generalized estimating equations. RESULTS: A total of 27,087 and 20,475 individuals participated at baseline and endline, respectively. Malaria prevalence decreased from 8.0 to 5.4% in the intervention arm for individuals of all ages and from 6.8 to 5.7% in the control arm. Pro-CCM was associated with a significant reduction in the odds of malaria positivity in children less than 15 years (OR = 0.59; 95% CI [0.38-0.91]), but not in older age groups. There was no impact on anemia among women of reproductive age. CONCLUSION: This trial suggests that pro-CCM approaches could help reduce malaria burden in rural endemic areas of low- and middle-income countries, but their impact may be limited to younger age groups with the highest malaria burden.

RESUMO

The existence of multiple perspectives and representations of different stakeholders poses critical challenges to conservation initiatives worldwide. Thus, to foster more just and sustainable agendas in protected areas (PAs), this diversity of perspectives must be better understood, acknowledged, and tackled. In this article, we aimed to initiate this understanding for the Makay region in Madagascar, a poorly-known region where a 'New Protected Area' has been gazetted. In combining mental models and social representation theory, we explored different stakeholders' perspectives about the Makay social-ecological system, and how differences in stakeholders' viewpoints could challenge the success of an inclusive, just, and sustainable conservation program. We conducted semi-structured interviews with 32 respondents having different expertise on the Makay. During interviews, respondents were guided towards the elicitation of their individual cognitive map (ICM) of the Makay social-ecological system. ICMs were then analyzed in combining quantitative and qualitative. Respondents described the Makay through a total of 162 components, including 51 components that constituted the central zone of the Makay's representation. In particular, respondents pointed to insecurity issues caused by zebu thieves, as well as to environmental challenges relative to anthropogenic fires and hunting. On the contrary, they considered mining activities and timber harvesting as more peripheral problems. Through a multivariate clustering analysis, we discriminated two clusters of respondents with contrasting visions about the Makay, ecocentric vs. social-ecological, which was largely influenced by respondents' background. In comparing the two clusters' representations, we found that they had dissimilar diagnoses about key socio-environmental challenges in the Makay and how to address them. This ambiguity in respondents' viewpoints stresses the need to increase research efforts in the Makay region to fill current knowledge gaps about this poorly known social-ecological system, and to foster social learning between stakeholders concerned by the Makay new PA.

RESUMO

OBJECTIVES: We aimed to determine the rate of catastrophic health expenditure incurred by women using maternal healthcare services at faith-based hospitals in Madagascar. DESIGN: This was a secondary analysis of programmatic data obtained from a non-governmental organisation. SETTING: Two faith-based, secondary-level hospitals located in rural communities in southern Madagascar. PARTICIPANTS: All women using maternal healthcare services at the study hospitals between 1 March 2019 and 7 September 2020 were included (n=957 women). MEASURES: We collected patient invoices and medical records of all participants. We then calculated the rate of catastrophic health expenditure relative to 10% and 25% of average annual household consumption in the study region. RESULTS: Overall, we found a high rate of catastrophic health expenditure (10% threshold: 486/890, 54.6%; 25% threshold: 366/890, 41.1%). Almost all women who required surgical care, most commonly a caesarean section, incurred catastrophic health expenditure (10% threshold: 279/280, 99.6%; 25% threshold: 279/280, 99.6%). The rate of catastrophic health expenditure among women delivering spontaneously was 5.7% (14/247; 10% threshold). CONCLUSIONS: Our findings suggest that direct patient costs of managing pregnancy and birth-related complications at faith-based hospitals are likely to cause catastrophic health expenditure. Financial risk protection strategies for reducing out-of-pocket payments for maternal healthcare should include faith-based hospitals to improve health-seeking behaviour and ultimately achieve universal health coverage in Madagascar.

RESUMO

Understanding local knowledge about wild edible plants (WEP) is essential for assessing plant services, reducing the risks of knowledge extinction, recognizing the rights of local communities, and improving biodiversity conservation efforts. However, the knowledge of specific groups such as women or children tends to be under-represented in local ecological knowledge (LEK) research. In this study, we explore how knowledge of WEP is distributed across gender and life stages (adults/children) among Betsileo people in the southern highlands of Madagascar. Using data from free listings with 42 adults and 40 children, gender-balanced, we show that knowledge on WEP differs widely across gender and life stage. In addition, we find that children have extended knowledge of WEP while reporting different species than adults. Women's knowledge specializes in herbaceous species (versus other plant life forms), while men's knowledge specializes in endemic species (versus native or introduced). Finally, we find that introduced species are more frequently cited by children, while adults cite more endemic species. We discuss the LEK differentiation mechanisms and the implications of acquiring life stage's knowledge in the highland landscapes of Madagascar. Given our findings, we highlight the importance of considering groups with under-represented knowledge repositories, such as children and women, into future research.

RESUMO

Schistosomiasis control requires multisectoral approaches including praziquantel treatment, access to safe water, sanitation and hygiene, and health education. Community input can help ensure health education programs are culturally appropriate to effectively direct protective behavior change. This study reports on the three-stage development of an education program for Malagasy children, with an impact evaluation on their knowledge, attitudes, and practices (KAP) related to intestinal schistosomiasis. A cross-sectional study took place in 2017 with follow-up in 2018 in the hard-to-reach Marolambo district, Madagascar. A novel schistosomiasis education program (SEP) was designed in collaboration with researchers, stakeholders, and local community and included cartoon books, games, songs, puzzles, and blackboard lessons, costing $10 USD per school. KAP questionnaires were completed by 286 children pre-SEP and 273 children post-SEP in 2017, and by 385 and 337 children pre-SEP and post-SEP, respectively, in 2018. Improvements were observed in responses to all questions between pre- and post-education answers in 2017 (53-77%, P < 0.0001) and 2018 (72-98%, P < 0.0001) and in the pre-education answers between years (53-72%, P < 0.0001). Praziquantel mass drug administration attendance improved, rising from 64% to 91% (P < 0.0001), alongside improved latrine use, from 89% to 96% (P = 0.005). This community-consulted and -engaged SEP resulted in substantial improvements in children's understanding of schistosomiasis, with improvements in praziquantel uptake and latrine use. Socioculturally tailored education programs can help gain schistosomiasis control. Continued investment in SEP will help promote the future well-being of children through increased participation in control and treatment activities.

RESUMO

BACKGROUND: To reach global immunisation goals, national programmes need to balance routine immunisation at health facilities with vaccination campaigns and other outreach activities (eg, vaccination weeks), which boost coverage at particular times and help reduce geographical inequalities. However, where routine immunisation is weak, an over-reliance on vaccination campaigns may lead to heterogeneous coverage. Here, we assessed the impact of a health system strengthening (HSS) intervention on the relative contribution of routine immunisation and outreach activities to reach immunisation goals in rural Madagascar. METHODS: We obtained data from health centres in Ifanadiana district on the monthly number of recommended vaccines (BCG, measles, diphtheria, tetanus and pertussis (DTP) and polio) delivered to children, during 2014-2018. We also analysed data from a district-representative cohort carried out every 2 years in over 1500 households in 2014-2018. We compared changes inside and outside the HSS catchment in the delivery of recommended vaccines, population-level vaccination coverage, geographical and economic inequalities in coverage, and timeliness of vaccination. The impact of HSS was quantified via mixed-effects logistic regressions. RESULTS: The HSS intervention was associated with a significant increase in immunisation rates (OR between 1.22 for measles and 1.49 for DTP), which diminished over time. Outreach activities were associated with a doubling in immunisation rates, but their effect was smaller in the HSS catchment. Analysis of cohort data revealed that HSS was associated with higher vaccination coverage (OR between 1.18 per year of HSS for measles and 1.43 for BCG), a reduction in economic inequality, and a higher proportion of timely vaccinations. Yet, the lower contribution of outreach activities in the HSS catchment was associated with persistent inequalities in geographical coverage, which prevented achieving international coverage targets. CONCLUSION: Investment in stronger primary care systems can improve vaccination coverage, reduce inequalities and improve the timeliness of vaccination via increases in routine immunisations.

RESUMO

BACKGROUND: The provision of emergency and hospital care has become an integral part of the global vision for universal health coverage. To strengthen secondary care systems, we need to accurately understand the time necessary for populations to reach a hospital. The goal of this study was to develop methods that accurately estimate referral and prehospital time for rural districts in low and middle-income countries. We used these estimates to assess how local geography can limit the impact of a strengthened referral programme in a rural district of Madagascar. METHODS: We developed a database containing: travel speed by foot and motorised vehicles in Ifanadiana district; a full mapping of all roads, footpaths and households; and remotely sensed data on terrain, land cover and climatic characteristics. We used this information to calibrate estimates of referral and prehospital time based on the shortest route algorithms and statistical models of local travel speed. We predict the impact on referral numbers of strategies aimed at reducing referral time for underserved populations via generalised linear mixed models. RESULTS: About 10% of the population lived less than 2 hours from the hospital, and more than half lived over 4 hours away, with variable access depending on climatic conditions. Only the four health centres located near the paved road had referral times to the hospital within 1 hour. Referral time remained the main barrier limiting the number of referrals despite health system strengthening efforts. The addition of two new referral centres is estimated to triple the population living within 2 hours from a centre with better emergency care capacity and nearly double the number of expected referrals. CONCLUSION: This study demonstrates how adapting geographic accessibility modelling methods to local scales can occur through improving the precision of travel time estimates and pairing them with data on health facility use.

RESUMO

In recent decades, microfinance institutions with financial products designed for low income groups have been established all over the world. However, credit access for farmers in developing countries remains low. Digital financial services are rapidly expanding globally at the moment. They also bear great potential to address the credit needs of farmers in remote rural areas. Beyond mobile money services, digital credit is successively offered and also discussed in literature. Compared to conventional credit which is granted based on a thorough assessment of the loan applicant's financial situation, digital credit is granted based on an automated analysis of the existing data of the loan applicant. Despite the potential of digital credit for serving the credit needs of rural farmers, empirical research on farmers' willingness to pay for digital credit is non-existent. We employ a discrete choice experiment to compare farmers' willingness to pay for digital and conventional credit. We apply loan attributes which reflect typical characteristics of both credit products. Our results indicate a higher willingness to pay for digital credit compared to conventional credit. Furthermore, we find that the proximity to withdraw borrowed money has a higher effect on farmers' willingness to pay for digital credit compared to conventional credit. Furthermore, our results show that instalment repayment condition reduces farmers' willingness to pay for digital credit whilst increasing their willingness to pay for conventional credit. Additionally, we find that longer loan duration has a higher effect on farmers' willingness to pay for digital credit compared to conventional credit whereas higher additional credit cost has a lower effect on farmers' willingness to pay for conventional credit compared to digital credit. Our results highlight the potential of digital credit for agricultural finance in rural areas of Madagascar if a certain level of innovation is applied in designing digital credit products.
