Background: the aim of this study is to evaluate the effectiveness and coverage of a simplified protocol that is implemented in health centers (HCs) and health posts (HPs) for children who are suffering from severe acute malnutrition (SAM) in the humanitarian context of Diffa. Methods: We conducted a non-randomized community-controlled trial. The control group received outpatient treatment for SAM, without medical complications, at HCs and HPs with the standard protocol of community management of acute malnutrition (CMAM). Meanwhile, with respect to the intervention group, the children with SAM received treatment at the HCs and HPs through a simplified protocol wherein the mid-upper arm circumference (MUAC) and the presence of edema were used as the admission criteria, and the children with SAM were administered doses of fixed ready-to-use therapeutic food (RUTF). Results: A total of 508 children, who were all under 5 years and had SAM, were admitted into the study. The cured proportion was 87.4% in the control group versus 96.6% in the intervention group (p value = 0.001). There was no difference between the groups in the length of stay, which was 35 days, but the intervention group used a lower quantity of RUTF—70 sachets versus 90 sachets, per child cured. Coverage increases were observed in both groups. Discussion: the simplified protocol used at the HCs and HPs did not result in worse recovery and resulted in fewer discharge errors compared to the standard protocol.

Currently, child acute malnutrition continues to be a serious public health problem, and although its most fatal consequences are well known, its associated factors still need to be studied in more depth in different contexts. The objective of the present study is to determine the association between socioeconomic variables and acute malnutrition severity in rural emergency contexts of Niger and Mali. The present study consists of a secondary analysis of controlled trials. Data related to a total of 1447 treated children (6–59 months of age) were considered, for whom the Variable Selection Using Random Forests (VSURF) algorithm was applied to create interpretation and prediction random forest models (considering 86 variables). In Mali and Niger, the prediction models agree in pointing out aspects related to the water source and the work activity of caregivers as some of the main risk factors for developing severe acute malnutrition. However, the interpretation models highlight important heterogeneity, with the distance to the health center being the greatest exponent of this situation, being the most important factor in Niger while disappearing in Mali. The prediction accuracy in the interpretation model was 68.0% in Niger and 79.80% in Mali, while the prediction model reached similar rates of 63.17% and 75.63%, respectively. Machine learning techniques have proven to be a valid tool to interpret and predict the degree of severity of acute malnutrition based on socioeconomic characteristics, including complex interrelationships. The results obtained point out different aspects to be addressed to prevent and minimize the effects of acute malnutrition. Acute malnutrition remains a critical health issue in rural emergency contexts of Niger and Mali. Using machine learning (VSURF algorithm), we analyzed socioeconomic risk factors in 1447 children. Water sources and caregivers' work emerged as key predictors. However, regional disparities exist, highlighting the need for context‐specific interventions to mitigate malnutrition severity. Summary Machine learning approaches are an effective tool to fight against child acute malnutrition. Random forest models correctly identify most severe cases of child acute malnutrition only using socioeconomic/environmental variables. The factors that have been identified as most associated with an increase in the severity of malnutrition are those related to water, access to health care, and socioeconomic status. The underlying factors of acute malnutrition were different in Mali and Niger and these contextual differences reveal the importance of tailoring medical interventions to optimize case diagnosis in emergency contexts and the orientation of public policies.

The Association between Iron and Folic Acid Supplementation and Malaria Prophylaxis and Linear Growth among Children and Neonatal Mortality in Sub-Saharan Africa—A Pooled Analysis
2022
The majority of research on linear growth among children is confined to South Asia and focuses on iron and folic acid (IFA) supplementation during pregnancy, without considering malaria prophylaxis. Similarly, there is limited evidence on the association of antenatal IFA supplementation and malaria prophylaxis with neonatal mortality in sub-Saharan Africa (SSA). This study aims to address these gaps. A pooled analysis of demographic and health survey (DHS) data from 19 countries in SSA was conducted to study the association between IFA supplementation and malaria prophylaxis and linear growth and neonatal mortality. Multivariate logistic and linear regression models were used. Malaria prophylaxis was significantly associated with stunting, height-for-age Z scores (HAZ scores), and neonatal mortality, but IFA supplementation was not associated with these outcomes. When women’s height and body mass index (BMI) were introduced in the model, a significant association between combined malaria prophylaxis and IFA supplementation was found with HAZ scores only. For severe stunting, no significant association was found with either in the two models. In conclusion, this study underscores the importance of antenatal malaria prophylaxis as a potential intervention for nutrition outcomes (linear growth) and neonatal mortality, as well as the importance of coordinating efforts between malaria and the health and nutrition sectors to improve these outcomes in the countries of SSA.

The present study aimed to assess the effectiveness and impact on treatment coverage of integrating severe acute malnutrition (SAM) treatment at the health hut level by community health workers (CHWs). This study was a non-randomized controlled trial, including two rural communes in the health district of Mayahi: Maïreyreye (control) and Guidan Amoumoune (intervention). The control group received outpatient treatment for uncomplicated SAM from health facilities (HFs), while the intervention group received outpatient treatment for uncomplicated SAM from HFs or CHWs. A total of 2789 children aged 6–59 months with SAM without medical complications were included in the study. The proportion of cured children was 72.1% in the control group, and 77.2% in the intervention group. Treatment coverage decreased by 8.3% in the control area, while the group of CHWs was able to mitigate that drop and even increase coverage by 3%. This decentralized treatment model of acute malnutrition with CHWs allowed an increase in treatment coverage while maintaining a good quality of care. It also allowed the early inclusion of children in less severe conditions. These results may enhance the Niger Ministry of Health to review the management of SAM protocol and allow CHWs to treat acute malnutrition.

Effects of iodine and selenium depletion on growth and bone quality of rats
2005
Scope and method of study. This project investigated the effects of experimental Iodine (I) and/or selenium (Se) depletion on bone density, structure, and strength in young rats. Dams were fed experimental diets beginning at week 1 of lactation. Pups were weaned at 3 wks of age and a sub-sample of males and females were fed the experimental diet of their mother for an additional 7 wks. I and Se status and growth in the animals were assessed. Bones quality of the rats was investigated for biochemical markers of bone metabolism, bone density, structure, and strength. Oxidative status was also assessed. Findings. Weight gain was decreased by I depletion in all animals and by Se depletion in males. Thyroid weight was increased and serum thyroxine (T4) was reduced by I deficiency. Se depletion was confirmed by lower hepatic glutathione peroxidase activity. Tri-iodothyronine (T3) was higher in female rats when Se was deficient. I and Se depletion independently decreased bone length and mineral area (BMA) in tibia and femur and selenium depletion decreased femur cortical thickness. There was higher bone turnover and lipid oxidation, and lower bone ash weight in male rats. BMA and bone mineral density (BMD) in vertebra, and bone mineral content in tibia, femur and vertebra were decreased by Se depletion in male rats as measured by DEXA. Analysis of proximal tibia and L3 trabecular bone by micro-computed tomography (μCT) showed a better bone microacthitecture in females than males and when Se was adequate, the deficiency of I increased the structural quality of both tibia and L3 trabecular bone. Tibia cortical bone volume and thickness were higher in males when Se was adequate. The compressive strength of L3 trabecular bone and the bending strength of femur were better in females. The breaking force of femur was higher in iodine adequate rats when Se was also adequate, and the adequacy of iodine increased femur stiffness in females. Iodine and/or selenium depletion impaired bone quality in growing rats.

Background
The Republic of Guinea, where malaria represents the leading cause of morbidity and mortality among children, the seasonal malaria chemoprevention (SMC) is deployed only in areas with very seasonal modes of transmission. It should target children at the highest risk of serious illness. The objective of the study was to prevent uncomplicated and serious cases of malaria in the target population. This study aimed to analyse the monthly trends in malaria-related morbidity among children under the age of 5 in Guinea.
Methods
This was a quasi-experimental study with routine data from the National Health Information System (SNIS). The two districts Mamou (the SMC intervention site) and Kindia (the control site) were selected to compare the monthly trends in malaria cases among children under the age of 5, from July to October, covering the years from 2015 to 2020. The statistical analysis used interrupted time series to estimate the effects of the SMC.
Results
The SMC programme contributed to a significant average reduction in the number of malaria cases of 225 cases per month in the intervention district (95% CI − 362 to − 88; p = 0.002), compared to the control district. However, the study also revealed that the effect of SMC varied between cycles, presenting different monthly malaria cases.
Conclusion
The SMC contributed to a significant reduction in malaria cases among children under the age of 5 in the health district of Mamou from 2018 to 2020. However, this reduction varied by monthly SMC cycle. This study suggests extending the SMC in other areas with high perennial seasonal transmission respecting the World Health Organization SMC eligibility criteria, as a strategy in the dynamic of reducing malaria cases in children under the age of 5 in Guinea.

Malaria incidence is generally lower in cities than rural areas. However, reported urban malaria incidence may not accurately reflect the level of ongoing transmission, which has potentially large implications for prevention efforts. To guide mosquito net distribution, we assessed the extent of malaria transmission in Conakry, Guinea, in 2018. We found evidence of active malaria transmission.

Prevalence and factors associated with unskilled childbirth attendance in Guinea
2024
This study aimed to analyze the prevalence and factors associated with the unassisted delivery by qualified health personnel in the Republic of Guinea, based on data from the 2018 demographic and health survey. Multivariate logistic regression was used to identify the associated factors. The prevalence of unassisted delivery was 40.8%; it was 38.4% in rural areas and 2.3% in urban areas. Factors associated with this type of delivery included the performance of no ANC (ORa = 6.19 IC95%: [4.86 - 7.87], p<0.001) and those who had performed one to three ANC (ORa =1.75 IC95%: [1.49 - 2.05], p<0.001) the perception of the distance to the health institution as a problem (ORa =1.28 IC95%: [1.10 - 1.48], p<0.001), belonging to the poor wealth index (ORa = 2.77 IC 95%: [2.19 - 3.50], p<0.001) and average (ORa = 2.01 IC95%: [1.57 - 2.57], p<0.001), the fact of residing in the region of Faranah (ORa = 2.24 IC95%: [1.37 - 3.65], p<0.001) and rural areas (ORa = 4.15 IC95%: [3.10 - 5.56], p<0.001). Strengthening community awareness, making functional ambulances available to rural health centers and making prenatal care inputs available in health institutions would help to reduce the scale of unassisted deliveries in the Republic of Guinea.
Cette étude visait à analyser la prévalence et les facteurs associés à l'accouchement non assisté par un personnel de santé qualifié en Guinée, partant des données de l'enquête démographique et de santé de 2018. La régression logistique multivariée a servi à identifier les facteurs associés. La fréquence de l'accouchement non assisté était de 40.8% ; elle était de 38.4% en milieu rural et 2.3% en milieu urbain. Les facteurs associés à ce type d'accouchement comprenaient la réalisation d'aucune CPN (ORa =6.19 IC95% : [4.86 - 7.87], p<0.001) et celles qui avaient réalisées une à trois CPN (ORa =1.75 IC95% : [1.49 - 2.05], p<0.001) la perception de la distance pour la structure de santé comme un problème (ORa =1.28 IC95% : [1.10 - 1.48], p<0.001), l'appartenance à l'indice de richesse pauvre (ORa =2.77 IC95% : [2.19 - 3.50], p<0.001) et moyenne (ORa =2.01 IC 95% : [1.57 - 2.57], p<0.001), le fait de résider dans la région de Faranah (ORa =2.24 IC95% : [1.37 - 3.65], p<0.001) et rurale (ORa =4,15 IC 95% : [3,10 - 5,56], p<0,001). Le renforcement de la sensibilisation communautaire, la mise d'ambulances fonctionnelles à la disposition des centres de santé ruraux et rendre disponible les intrants de soins prénatals dans les structures sanitaires contribueraient serte à réduire l'ampleur des accouchements non assistés en Guinée.

This study aimed to analyze factors associated with obstetric fistula care-seeking behavior in Guinea, based on data from the 2018 Demographic and Health Survey. Women aged 15-49 years who reported having obstetric fistula constituted the study population, statistical analysis was using Stata 16.0 software. Multivariate logistic regression was used to identify the factors associated with fistula care-seeking behavior. Among women with obstetric fistula, 78.9% sought care; 21.1% of those who sought care underwent repair. Factors associated with care-seeking behavior were being divorced (AOR =8.08; 95% CI:1.56-41.84), having a job (AOR =3.23; 95% CI: 1.11-9.44), being a member of a poor household (AOR =6.49; 95% CI:1.21-34.82) and whose fistula had appeared 6 days or more after the occurrence of the causal circumstance (AOR =3.63 95% CI: 1.28-10.28). This study suggests that the foundations on which fistula prevention and treatment programs are built should be reviewed, taking into account the factors highlighted by this study.
Cette étude visait à analyser les facteurs associés aux comportements de recherche de soins pour la fistule obstétricale en Guinée, partant des données de l'enquête démographique et de santé de 2018. Les femmes âgées de 15 à 49 ans ayant déclaré avoir une fistule obstétricale ont constitué la population d'étude, l'analyse statistique a été réalisée à l'aide du logiciel Stata 16.0. La régression logistique multivariée a été utilisée pour identifier les facteurs associés aux comportements de recherche de soins pour la fistule. Parmi les femmes atteintes de fistule obstétricale, 78,9 % ont eu recours à des soins ; 21,1 % de celles qui ont recouru ont subi une réparation. Les facteurs associés aux comportements de recherche de soins étaient le fait d'être divorcée (ORA=8.08 ; 95% IC :1.56-41.84), d'avoir un travail (ORA =3.23 ; 95% IC : 1.11-9.44), d'être membre d'un ménage pauvre (ORA =6.49 ; 95% IC :1.21-34.82) et dont la fistule était apparue 6 jours ou plus après la survenue de la circonstance causale (ORA =3.63 95% IC : 1.28-10.28). Cette étude suggère de revoir les bases sur lesquelles les programmes de prévention et de traitement de la fistule sont construits, tout en prenant en compte les facteurs mis en évidence par cette étude.
