RESUMO

BACKGROUND: Enabling community health workers (CHWs) to treat acute malnutrition improves treatment access and coverage. However, data on the cost and cost-effectiveness of this approach is limited. We aimed to cost the treatment at scale and determine the cost-effectiveness of different levels of supervision and technical support. METHODS: This economic evaluation was part of a prospective nonrandomized community intervention study in 3 districts in Mali examining the impact of different levels of CHW and health center supervision and support on treatment outcomes for children with severe acute malnutrition. Treatment admission and outcome data were extracted from the records of 120 participating health centers and 169 CHW sites. Cost data were collected from accountancy records and through key informant interviews. Results were presented as cost per child treated and cured. Modeled scenario sensitivity analyses were conducted to determine how cost-efficiency and cost-effectiveness estimates change in an equal scale scenario and/or if the supervision had been done by government staff. RESULTS: In the observed scenario, with an unequal number of children, the average cost per child treated was US$203.40 in Bafoulabé where a basic level of supervision and support was provided, US$279.90 in Kayes with a medium level of supervision, and US$253.9 in Kita with the highest level of supervision. Costs per child cured were US$303.90 in Bafoulabé, US$324.90 in Kayes, and US$311.80 in Kita, with overlapping uncertainty ranges. CONCLUSION: Additional supervision has the potential to be a cost-effective strategy if supervision costs are reduced without compromising the quality of supervision. Further research should aim to better adapt the supervision model and associated tools to the context and investigate where efficiencies can be made in its delivery.

RESUMO

BACKGROUND: Our recent studies have shown headache disorders to be very common in the central and western sub-Saharan countries of Benin and Cameroon. Here we report headache in nearby Mali, a strife-torn country that differs topographically, culturally, politically and economically. The purposes were to estimate headache-attributed burden and need for headache care. METHODS: We used cluster-random sampling in seven of Mali's eleven regions to obtain a nationally representative sample. During unannounced household visits by trained interviewers, one randomly selected adult member (18-65 years) from each household was interviewed using the structured HARDSHIP questionnaire, with enquiries into headache in the last year and, additionally, headache yesterday (HY). Headache on ≥ 15 days/month (H15+) was diagnosed as probable medication-overuse headache (pMOH) when associated with acute medication use on ≥ 15 days/month, and as "other H15+" when not. Episodic headache (on < 15 days/month) was recorded as such and not further diagnosed. Burden was assessed as impaired participation (days lost from paid and household work, and from leisure activity). Need for headache care was defined by criteria for expectation of benefit. RESULTS: Data collection coincided with the SARS-CoV-2 pandemic. The participating proportion was nonetheless extremely high (99.4%). The observed 1-year prevalence of any headache was 90.9%. Age- and gender-adjusted estimates were 86.3% for episodic headache, 1.4% for pMOH and 3.1% for other H15+. HY was reported by 16.8% with a mean duration of 8.7 h. Overall mean headache frequency was 3.5 days/month. Participants with pMOH lost more days from paid (8.8 days/3 months) and household work (10.3 days/3 months) than those with other H15+ (3.1 and 2.8 days/3 months) or episodic headache (1.2 and 0.9 days/3 months). At population level, 3.6-5.8% of all time was spent with headache, which led to a 3.6% decrease in all activity (impaired participation). Almost a quarter (23.4%) of Mali's adult population need headache care. CONCLUSION: Headache is very common in Mali, as in its near neighbours, Benin and Cameroon, and associated with substantial losses of health and productivity. Need for headache care is high - a challenge for a low-income country - but lost productivity probably translates into lost gross domestic product.

RESUMO

INTRODUCTION: The Health and Social Development Program of the Mopti Region (PADSS2) project, launched in Mali's Mopti region, targeted Universal Health Coverage (UHC). The project addressed demand-side barriers by offering an additional subsidy to household contributions, complementing existing State support (component 1). Component 2 focused on supply-side improvements, enhancing quality and coverage. Component 3 strengthened central and decentralised capacity for planning, supervision and UHC reflection, integrating gender mainstreaming. The study assessed the impact of the project on maternal and child healthcare use and explored how rising terrorist activities might affect these health outcomes. METHODS: The impact of the intervention on assisted births, prenatal care and curative consultations for children under 5 was analysed from January 2016 to December 2021. This was done using an interrupted time series analysis, incorporating a comparison group and spline regression. RESULTS: C1 increased assisted deliveries by 0.39% (95% CI 0.20 to 0.58] and C2 by 1.52% (95% CI 1.36 to 1.68). C1-enhanced first and fourth antenatal visits by 1.37% (95% CI 1.28 to 1.47) and 2.07% (95% CI 1.86 to 2.28), respectively, while C2 decreased them by 0.53% and 1.16% (95% CI -1.34 to -0.99). For child visits under 5, C1 and C2 showed increases of 0.32% (95% CI 0.20 to 0.43) and 1.36% (95% CI 1.27 to 1.46), respectively. In areas with terrorist attacks, child visits decreased significantly by 24.69% to 39.86% compared with unexposed areas. CONCLUSION: The intervention had a limited impact on maternal and child health, falling short of expectations for a health system initiative. Understanding the varied effects of terrorism on healthcare is key to devising strategies that protect the most vulnerable in the system.

RESUMO

BACKGROUND: In patients with severe neutropenia, infections can rapidly become serious and life-threatening. It is essential to understand whether pregnancy induces changes in neutrophil levels thereby posing an increased threat to the health of gravidae. METHODOLOGY: This cross-sectional study was conducted in San Health District (Mali) and involved pregnant women infected or not by malaria parasites and non-pregnant healthy volunteers. Subjects were categorized as having neutropenia, normal neutrophil levels, and neutrophilia regarding their neutrophil levels. A logistic regression analysis was performed to determine factors associated with neutrophil level variation in pregnant women. RESULTS: Whether or not the pregnant women were infected with malaria, 98 of the 202 cases (48.5%) showed neutrophilia. Surprisingly, 67 of the 71 cases of neutropenia (94.4%) observed in this study concerned healthy people who were not pregnant. The mean percentage of neutrophil levels was significantly (p < 0.001) lower (49.9%) in the first trimester compared to the second trimester of pregnancy (62.0%). A logistic regression model showed that compared to early pregnancy, the second (OR = 12.9, 95% CI 2.2-248.1, p = 0.018) and the third trimesters (OR = 13.7, 95% CI 2.3-257.5, p = 0.016) were strongly associated with the increase of neutrophil levels. CONCLUSIONS: Pregnancy can induce the production of mature neutrophils that are continually released into circulation. Neutrophil levels were lower during the first trimester of the pregnancy compared to the second and third trimesters, but not affected by the presence or absence of malaria infection.

RESUMO

BACKGROUND: Little is known about costs and cost effectiveness of interventions that integrate wasting prevention into screening for child wasting. OBJECTIVES: This study's objective was to estimate the cost and cost-effectiveness of an intervention that integrated behavior change communication (BCC) and small-quantity lipid-based nutrient supplements (SQ-LNS) into platforms for wasting screening in Burkina Faso (a facility-based platform, where BCC was enhanced compared with standard care) and Mali (a community-based platform, with standard BCC). METHODS: Activity-based costing was used to estimate the cost per child-contact for the intervention and the comparison group, which did not receive the intervention. Costs were ascertained from accounting records, interviews, surveys, and observations. The number of child-contacts was calculated using population size estimates and average attendance rates for each service. Costs per disability-adjusted life year (DALY) averted were estimated using a Markov model populated with data from the parent trials on impact of wasting incidence and treatment coverage. RESULTS: In the intervention group in Burkina Faso, the cost per child-contact of facility-based screening was $0.85 of enhanced BCC was $4.28, and of SQ-LNS was $8.86. In Mali, the cost per child-contact of community-based screening was $0.57, standard BCC was $0.72, and SQ-LNS was $4.14. Although no SQ-LNS costs were incurred in the comparison groups (hence lower total costs), costs per child-contact for screening and BCC were higher because coverage of these services was lower. The intervention package cost $1073 per DALY averted in Burkina Faso and $747 in Mali. CONCLUSIONS: Integration of wasting prevention into screening for child wasting led to higher total costs but lower unit costs than standard screening due to increased coverage. Greater cost-effectiveness could be achieved if BCC were strengthened and led to improved caregiver health and nutrition practices and if screening triggered appropriate use of services and higher treatment coverage.

RESUMO

INTRODUCTION: Using health facility types as a measure of service availability is a common approach in international standards for health system policy and planning. However, this proxy may not accurately reflect the actual availability of specific health services. OBJECTIVE: This study aims to evaluate the reliability of health facility typology as an indicator of specific health service availability and explore whether certain facility types consistently provide particular services. DESIGN: We analysed a comprehensive dataset containing information from 1725 health facilities in Mali. To uncover and visualise patterns within the dataset, we used two analytical techniques: Multiple Correspondence Analysis and Between-Class Analysis. These analyses allowed us to quantitatively measure the influence of health facility types on the variation in health service provisioning. Additionally, we developed and calculated a Consistency Index, which assesses the consistency of a health facility type in providing specific health services. By examining various health facilities and services, we sought to determine the accuracy of facility types as indicators of service availability. SETTING: The study focused on the health system in Mali as a case study. RESULTS: Our findings indicate that using health facility types as a proxy for service availability in Mali is not an accurate representation. We observed that most of the variation in service provision does not stem from differences between facility types but rather within facility types. This suggests that relying solely on health facility typology may lead to an incomplete understanding of health service availability. CONCLUSIONS: These results have significant implications for health policy and planning. The reliance on health facility types as indicators for health system policy and planning should be reconsidered. A more nuanced and evidence-based understanding of health service availability is crucial for effective health policy and planning, as well as for the assessment and monitoring of health systems.

RESUMO

INTRODUCTION: Mali has implemented social protection initiatives in the context of universal health coverage, including the RAMED (medical assistance plan). PURPOSE OF THE RESEARCH: This article describes the participatory process involving researchers and national technical staff as part of an action-research program linked to this policy. RESULTS: The process allowed the interests of the target public, those living in poverty, to take priority over individual and institutional interests, without, however, allowing for their active participation. Despite this positive outcome, the recommendations were not taken on board. CONCLUSION: The main failure of this process was its political component, but there is still time to address this.

RESUMO

OBJECTIVES: Every child around the globe should get routine childhood vaccination, which is mostly affected by the country's economic capacity besides the socioeconomic differences. However, how well countries with different economic capacities address equitable child vaccination remains unanswered. METHODS: Cross-sectional data from the latest Demographic and Health Survey (DHS) database of Mali, Bangladesh, and South Africa was used for this study. The dependent variable was full child vaccination, and wealth-based inequality was assessed using rate-ratio, concentration curve, and concentration index. A multilevel Poisson regression analysis was used to determine the predictors of inequalities. A risk ratio (RR) with a p-value of 0.05 was used to declare statistical significance. All analysis was weighted. RESULTS: Full child vaccination status was 30.15%, 62.18%, and 46.94% in Mali, Bangladesh, and South Africa respectively. Even if the disparity is higher in Mali, the full vaccination favors the better-off family both in Mali, and Bangladesh respectively [CInd: 0.05, 95% CI: 0.01, 0.09], [CInd: 0.02, 95% CI: 0.001, 0.03], wealth status did not have an effect in South Africa. The multilevel poison regression indicated maternal age, occupation, wealth of household, and frequency of watching television to positively affect full vaccination, whereas the number of children in the house negatively affected full vaccination. CONCLUSION: Wealth-based inequality in child vaccination was higher in Mali followed by Bangladesh. There was no observable significant equity gap in South Africa. Wealth status, maternal occupation, maternal age, frequency of watching television, and number of children were predictors of full child vaccination.

RESUMO

INTRODUCTION: Many children in low-income and middle-income countries fail to receive any routine vaccinations. There is little evidence on how to effectively and efficiently identify and target such 'zero-dose' (ZD) children. METHODS: We examined how well predictive algorithms can characterise a child's risk of being ZD based on predictor variables that are available in routine administrative data. We applied supervised learning algorithms with three increasingly rich sets of predictors and multiple years of data from India, Mali and Nigeria. We assessed performance based on specificity, sensitivity and the F1 Score and investigated feature importance. We also examined how performance decays when the model is trained on older data. For data from India in 2015, we further compared the inclusion and exclusion errors of the algorithmic approach with a simple geographical targeting approach based on district full-immunisation coverage. RESULTS: Cost-sensitive Ridge classification correctly classifies most ZD children as being at high risk in most country-years (high specificity). Performance did not meaningfully increase when predictors were added beyond an initial sparse set of seven variables. Region and measures of contact with the health system (antenatal care and birth in a facility) had the highest feature importance. Model performance decreased in the time between the data on which the model was trained and the data to which it was applied (test data). The exclusion error of the algorithmic approach was about 9.1% lower than the exclusion error of the geographical approach. Furthermore, the algorithmic approach was able to detect ZD children across 176 more areas as compared with the geographical rule, for the same number of children targeted. INTERPRETATION: Predictive algorithms applied to existing data can effectively identify ZD children and could be deployed at low cost to target interventions to reduce ZD prevalence and inequities in vaccination coverage.

RESUMO

The COVID-19 pandemic has led to an unprecedented global crisis. It has exposed and exacerbated weaknesses in public health systems worldwide, particularly with regards to reaching the most vulnerable populations, disproportionately impacted by the pandemic. The objective of our study was to examine whether and how social inequalities in health (SIH) were considered in the design and planning of public health responses to COVID-19 in jurisdictions of Brazil, Canada, France, and Mali. This article reports on a qualitative multiple case study of testing and contact tracing interventions in regions with high COVID-19 incidence in each country, namely: Manaus (Brazil), Montréal (Canada), Île-de-France (France), and Bamako (Mali). We conducted interviews with 108 key informants involved in these interventions in the four jurisdictions, focusing on the first and second waves of the pandemic. We analyzed our data thematically using a theoretical bricolage framework. Our analysis suggests that the lack of a common understanding of SIH among all actors involved and the sense of urgency brought by the pandemic eclipsed the prioritization of SIH in the initial responses. The pandemic increased intersectoral collaboration, but decision-making power was often unequal between Ministries of Health and other actors in each jurisdiction. Various adaptations to COVID-19 interventions were implemented to reach certain population groups, therefore improving the accessibility, availability, and acceptability of testing and contact tracing. Our study contributes to identifying lessons learned from the current pandemic, namely that the ways in which SIH are understood shape how interventions are planned; that having clear guidelines on how to integrate SIH into public health interventions could lead to more inclusive pandemic responses; that for intersectoral collaboration to be fruitful, there needs to be sufficient resources and equitable decision-making power between partners; and that interventions must be flexible to respond to emerging needs while considering long-standing structural inequalities.

RESUMO

BACKGROUND: This study examines how the functioning of healthcare providers during the COVID-19 pandemic was affected by the government financing response, which was shaped by existing healthcare financing systems. METHODS: The study applied a single case study design at a tertiary hospital in Bamako during the 1st and 2nd waves of the COVID-19 pandemic. Data were gathered through 51 in-depth interviews with hospital staff, participatory observation, and reviewing media articles and hospital financial records. RESULTS: The study revealed the disruptions experienced by hospital managers, human resources for health and patients in Mali during the early stages of the pandemic. While the government aimed to support universal access to COVID-19-related services, efforts were undermined by issues associated with complex public financing management procedures. The hospital experienced long delays in transferring government funds. The hospital suffered a decrease in revenue during the early stages of the pandemic. Government budgets were not effectively used because of complex, non-agile procedures that could not adapt to the emergency. The challenges faced by the hospitals led to the delays in the staff payments of salaries and promised bonuses, which created potential for unfair treatment of patients. Excluding some COVID-19 related items from the government funded benefit package created a financial burden on people receiving services. The managerial challenges experienced in the study hospital during the first wave continued in the second wave. CONCLUSIONS: Pre-existent issues in healthcare financing and governance constrained the effective management of COVID-19-related services and created confusion at the front line of healthcare service delivery.

RESUMO

INTRODUCTION: Anemia is a severe global public health problem that threatens human health as well as social and economic development in both developing and developed nations. Anemia is a significant public health issue because; it affects people from all backgrounds. Anemia affected about one-third of non-pregnant women, 41.8% of pregnant women, and more than a quarter of the world's population. Any stage of a woman's life might result in anemia, due to physiological factors, infections, hormonal imbalances, pregnancy related complications, genetic factors, nutritional deficiency and environmental factors. Mali is a developing country with substantial anemia prevalence, particularly in the developing areas. In order to reduce anemia among women of reproductive age, the Mali government worked to enhance preventative and integrative interventions. One of the government's objectives is to reduce the prevalence of anemia in order to decrease maternal and infant mortality and morbidity. METHODS: Secondary data analysis was conducted using data from Mali Malaria Indicator Survey 2021 datasets. The study comprised a total of 10,765 reproductive-age women. Spatial and multilevel mixed effect analysis, chi-square, bivariate and multivariate logistic regression were employed on determinant factors of anemia among reproductive age women in Mali. Finally, the percentage and odd ratio, its 95% confidence intervals, and the result of spatial analysis were reported. RESULTS: This study includes a total weighted sample of 10,765 reproductive-age women from Mali Malaria Indicator Survey 2021. The prevalence of anemia was 38%. Of them, 1.4%, were severely anemic, while 23.5% and 13.1% were moderately and mildly anemic, respectively in Mali. In the spatial analysis, the spatial distribution of anemia showed that a higher proportion of anemia found in southern and south west region of Mali. The northern and north east region of Mali had a low of proportion of anemia. being youngest age [20-24] years [ AOR = 0.817; 95% CI = (0.638,1.047); P = 0.000], attending higher education [AOR = 0.401; 95% CI= (0.278,0.579); P = 0.000], being male headed household [AOR = 0.653; 95% CI= (0.536,0.794); P = 0.000] and being richest [AOR = 0.629; 95% CI= (0.524,0.754) P = 0.000] were protective factors for anemia among reproductive age women. In contrast to this, living in rural area [ AOR = 1.053; 95% CI = (0.880,1.260); P = 0.000], being animist religion follower [AOR = 3.10; 95% CI= (0.763,12.623) P = 0.04], using unimproved drinking water sources [AOR = 1.117; CI= (1.017,1.228); P = 0.021} and using unimproved toilet facility [AOR = 1.018; CI= (0.917,1.130); P = 0.041} were considered as the risk factors for anemia among reproductive age women. CONCLUSION: In this study, anemia was linked to socio-demographic characteristics, and there were regional variations in the frequency of anemia among women of reproductive age. The most important measures to prevent anemia among women of reproductive age in Mali included empowering women to have higher levels of education, raising the wealth index, rise in awareness of improved drinking water sources and toilet facilities, spreading anemia education through religiously acceptable routes, and using an integrated approach to prevention and intervention in high-prevalent regions of the country.

RESUMO

The Niger River, Bamako's population's primary drinking water source, is threatened by human activities. This study examines the Niger River pollution trend using heavy metals pollution indexes and Bamako's population's non-carcinogenic and carcinogenic related health risks. Parameters were monitored at fifteen sampling locations in low and high flow seasons. pH (7.30-7.50) and fluoride (0.15-0.26 mg/L) were within the normal drinking water range. Among seven heavy metals (copper, zinc, cadmium, nickel, iron, manganese, and lead), the latter three were above the drinking water standard. The degree of contamination was negative, pointing to better water quality. However, the heavy metal evaluation index (HEI) was below the mean (5.88), between the mean and twice the mean, indicating a low and medium degree of pollution. Besides, heavy metal pollution indexes (HPI) were above the standard value (100), explaining a low-medium pollution level. High values of HPI could be explained by the industrial units' intensive activities coupled with the runoff effect. The hazard index (HI) indicated a low and medium non-carcinogenic health risk for adults and children. The probability of cancer risk (PCR) of nickel showed a cancer risk. Therefore, the river was polluted with trace elements and could not be used for drinking water without any treatment.

RESUMO

BACKGROUND: The WHO recommends use of the RTS,S/AS01E (RTS,S) malaria vaccine for young children living in areas of moderate to high Plasmodium falciparum malaria transmission and suggests countries consider seasonal vaccination in areas with highly seasonal malaria. Seasonal vaccination is uncommon and may require adaptations with potential cost consequences. This study prospectively estimates cost of seasonal malaria vaccine delivery in Mali and Burkina Faso. METHODS: Three scenarios for seasonal vaccine delivery are costed (1) mass campaign only, (2) routine Expanded Programme on Immunisation (EPI) and (3) mixed delivery (mass campaign and routine EPI)), from the government's perspective. Resource use data are informed by previous new vaccine introductions, supplemented with primary data from a sample of health facilities and administrative units. FINDINGS: At an assumed vaccine price of US $5 per dose, the economic cost per dose administered ranges between $7.73 and $8.68 (mass campaign), $7.04 and $7.38 (routine EPI) and $7.26 and $7.93 (mixed delivery). Excluding commodities, the cost ranges between $1.17 and $2.12 (mass campaign), $0.48 and $0.82 (routine EPI) and $0.70 and $1.37 (mixed delivery). The financial non-commodity cost per dose administered ranges between $0.99 and $1.99 (mass campaign), $0.39 and $0.76 (routine EPI) and $0.58 and $1.28 (mixed delivery). Excluding commodity costs, service delivery is the main cost driver under the mass campaign scenario, accounting for 36% to 55% of the financial cost. Service delivery accounts for 2%-8% and 12%-23% of the total financial cost under routine EPI and mixed delivery scenarios, respectively. CONCLUSION: Vaccine delivery using the mass campaign approach is most costly followed by mixed delivery and routine EPI delivery approaches, in both countries. Our cost estimates provide useful insights for decisions regarding delivery approaches, as countries plan the malaria vaccine rollout.

RESUMO

BACKGROUND: Pediatric exposures to unsafe sources of water, unsafely managed sanitation, and animals are prevalent in low- and middle-income countries. In the Vaccine Impact on Diarrhea in Africa case-control study, we examined associations between these risk factors and moderate-to-severe diarrhea (MSD) in children <5 years old in The Gambia, Kenya, and Mali. METHODS: We enrolled children <5 years old seeking care for MSD at health centers; age-, sex-, and community-matched controls were enrolled at home. Conditional logistic regression models, adjusted for a priori confounders, were used to evaluate associations between MSD and survey-based assessments of water, sanitation, and animals living in the compound. RESULTS: From 2015 to 2018, 4840 cases and 6213 controls were enrolled. In pan-site analyses, children with drinking water sources below "safely managed" (onsite, continuously accessible sources of good water quality) had 1.5-2.0-fold higher odds of MSD (95% confidence intervals [CIs] ranging from 1.0 to 2.5), driven by rural site results (The Gambia and Kenya). In the urban site (Mali), children whose drinking water source was less available (several hours/day vs all the time) had higher odds of MSD (matched odds ratio [mOR]: 1.4, 95% CI: 1.1, 1.7). Associations between MSD and sanitation were site-specific. Goats were associated with slightly increased odds of MSD in pan-site analyses, whereas associations with cows and fowl varied by site. CONCLUSIONS: Poorer types and availability of drinking water sources were consistently associated with MSD, whereas the impacts of sanitation and household animals were context-specific. The association between MSD and access to safely managed drinking water sources post-rotavirus introduction calls for transformational changes in drinking water services to prevent acute child morbidity from MSD.

RESUMO

PURPOSE: The evaluation of mandibular third molar (M3) difficulty is extremely important. This study aims to measure the association between preoperative Lambade-Dawane-Mali's (LDM) M3 difficulty index and postoperative assessment of difficulty score. MATERIAL AND METHODS: This prospective cohort study included patients with impacted M3 reported to the Department of OMS, RRK Dental College, Akola, from 2017 to 2022. The preoperative surgical difficulty was estimated using the predictor, LDM index with scores, easy (15-25), moderate (25-30), and difficult (>30). The postoperative surgical difficulty was analyzed with the primary outcome variable, total time intervention measured from the beginning of incision to the final suturing, wherein extraction was classified as easy if time (<15 minutes), moderate (15-30 minutes), and difficult (>30 minutes). The secondary outcome variable, Modified Parant's Scale (MPS), defines four levels of difficulty required for extraction of M3: Easy I (forceps extraction), Easy II (requiring osteotomy), Difficult III (coronal sectioning), and Difficult IV (complex extraction). Data were analyzed using agreement between LDM difficulty with three established criteria (time, MPS, Pederson index) and were assessed with Cohen's Kappa statistics. McNemar's test for paired data was used to assess concordance between two criteria of evaluation with a P-value <.05 was considered statistically significant. RESULTS: The study sample included 1000 patients with a mean age of 26.7 ± 7.6 years and 456 (45.6%) females. Those assessed preoperatively with LDM to be difficult and easy outcomes were found upon postoperative assessment with MPS to be 99% and 99% correct, respectively. Inter-criteria agreement and Kappa statistics suggested a positive Kappa value (κ) and statistically significant agreement between the LDM index with perioperative time (κ = 0.8930), MPS (κ = 0.6488), and Pederson index (κ = 0.4920) at P-value 0.0001. Pair-wise comparisons of LDM criteria with perioperative time, MPS, and Pederson scale were assessed by McNemar's test, which evaluated concordance between the two criteria. CONCLUSION: Postoperative evaluation of surgical difficulty in M3 extraction was strongly correlated with preoperative variables in the LDM difficulty-scoring index. Preoperative evaluation helps in anticipating the difficulty, planning surgical management, and scheduling time more optimally.

RESUMO

BACKGROUND: Many Sahel countries in Africa are looking for solutions for universal health coverage (UHC). Mali is in the process of adopting the Universal Health Insurance Plan, which allows for the mutualisation of existing schemes. Its operationalisation requires numerous adjustments to the current mutualist proposal and innovations in the system. The study focuses on innovations experienced in mutuality and their conditions of scale for UHC in Mali. METHODS: This is qualitative research by multiple case studies. It is based on the collection of data by interviews (n=136), at a national and local level, on the analysis of documents (n=42) and a long field observation (7 months). The analytical framework concerns the dissemination and maintenance of health innovations (Greenhalgh et al, 2004). RESULT: The analysis of this innovation shows an interest in the technical and institutional viability that determines its performance and scale-up. The procrastination and scepticism displayed at the highest level of the state and the international level, the reluctance, both financial and ideological, to renew the old mutualist proposal, penalise this Malian experiment. CONCLUSION: This innovation is a decisive step in ensuring the health coverage of Mali's agricultural and informal sectors. The reform will need to be amplified and supported in the future to expect the scale-up of a cheaper, technically and institutionally more efficient system. Without a political intention to mobilise national resources and accept a fundamental paradigm shift in health financing, the search for the financial viability of mutuality may, again, be at the expense of the performance.

RESUMO

In the fight against infectious diseases, social inequalities in health (SIH) are generally forgotten. Mali, already weakened by security and political unrest, has not been spared by the COVID-19 pandemic. Although the country was unprepared, the authorities were quick to implement public health measures, including a SARS-CoV-2 testing programme. This study aimed to understand if and how social inequalities in health were addressed in the design and planning for the national COVID-19 testing policy in Mali. A qualitative survey was conducted between March and April 2021 in Bamako, the capital of Mali. A total of 26 interviews were conducted with key government actors and national and international partners. A document review of national reports and policy documents complemented this data collection. The results demonstrated that the concept of SIH was unclear to the participants and was not a priority. The authorities focused on a symptom-based testing strategy that was publicly available. Participants also mentioned some efforts to reduce inequalities across geographical territories. The reflection and consideration of SIH within COVID-19 interventions was difficult given the governance approach to response efforts. The urgency of the situation, the perceptions of COVID-19 and the country's pre-existing fragility were factors limiting this reflection. Over time, little action has been taken to adapt to the specific needs of certain groups in the Malian population. This study (re)highlights the need to consider SIH in the planning stages of a public health intervention, to adapt its implementation and to limit the negative impact on SIH.

RESUMO

Aflatoxin contamination of staple crops by Aspergillus flavus and closely related fungi is common across the Sahel region of Africa. Aflatoxins in maize, groundnut, and sorghum collected at harvest or from farmers' stores within two weeks of harvest from Burkina Faso, Mali, and Niger were quantified. Thereafter, aflatoxin exposure values were assessed using per capita consumption rates of those crops. Mean aflatoxin concentrations in maize were high, 128, 517, and 659 µg/kg in Mali, Burkina Faso, and Niger, respectively. The estimated probable daily intake (PDI) of aflatoxins from maize ranged from 6 to 69, 29 to 432, and 310 to 2100 ng/kg bw/day in Mali, Burkina Faso, and Niger, respectively. Similarly, mean aflatoxin concentrations in sorghum were high, 76 and 259 µg/kg in Mali and Niger, respectively, with an estimated PDI of 2-133 and 706-2221. For groundnut, mean aflatoxin concentrations were 115, 277, and 628 µg/kg in Mali, Burkina Faso, and Niger, respectively. Aflatoxin exposure values were high with an estimated 9, 28, and 126 liver cancer cases/100,000 persons/year in Mali, Burkina Faso, and Niger, respectively. Several samples were extremely unsafe, exceeding manyfold regulatory levels of diverse countries (up to 2000 times more). Urgent attention is needed across the Sahel for integrated aflatoxin management for public health protection, food and nutrition security, and access to trade opportunities.
