Multimodal pulse oximeters to support the integrated management of childhood illnesses: A usability and diagnostic accuracy assessment from a multi-country hybrid type 2 study
Open AccessHelen L Storey, Tessa L Fielding et al.ARTICLEPLOS Global Public Health2026
Nearly 5 million children die each year of preventable causes, with pneumonia being a key contributor. The Integrated Management of Childhood Illnesses guidelines improve health care workers’ diagnostic and management capabilities by relying mostly on clinical signs. Though there have been successes, challenges in the consistent application of IMCI and the accurate diagnosis of conditions like hypoxemia remain. Next generation pulse oximeters add…
Grazing Affects Soil Organic Carbon Stocks Directly and Indirectly Through Herbaceous Species Diversity in Sahelian Savanna Ecosystems
Open AccessHaftay Hailu Gebremedhn, Simon Taugourdeau et al.ARTICLELand Degradation and Development2025
The impact of livestock grazing on soil organic carbon (SOC) stocks in the Sahel has been poorly documented due to a lack of data from different grazing intensities. This study evaluated SOC stocks under four grazing intensities within 0–30 cm soil depth in dry savanna ecosystems of Senegal. It also examined possible indirect relationships between grazing and SOC through herbaceous species diversity, herbaceous biomass, and carbon–nitrogen ratio.…
Costs of testing sick children in primary care with pulse oximetry: Evidence from four countries, both with and without electronic clinical decision support
Open AccessSusan Horton, Ulrich Adombi et al.ARTICLEPLOS Global Public Health2025
Introducing pulse oximeters (PO) at primary care facilities can help health workers identify severely ill children who need referral to hospital thereby allowing for improved child clinical outcomes. Adding clinical decision support algorithms (CDSA) can improve adherence to Integrated Management of Childhood Illness guidelines. The current study analyses the costs of introducing PO either with or without an electronic CDSA using an RCT in India …
Machine Learning-Based Prediction of Heatwave-Related Hospitalizations: A Case Study in Matam, Senegal
Open AccessMory Touré, Ibrahima Sy et al.ARTICLEInternational Journal of…2025
This study assesses the impact of heatwaves on hospital admissions in the Matam region of Senegal by combining climatic indices with machine learning methods. Using daily maximum temperature (TMAX) and heat index (HI), heatwave events were identified from 2017 to 2022. Hospital data from Ourossogui Regional Hospital were analyzed, and three predictive models, Random Forest (RF), Extreme Gradient Boosting (XGB), and Generalized Additive Models (GA…
The Tools for Integrated Management of Childhood Illness (Timci) study protocol: A multi-country mixed-method evaluation of pulse oximetry and clinical decision support algorithms
Open AccessFenella Beynon, Hélène Langet et al.ARTICLEGlobal Health Action2024
Effective and sustainable strategies are needed to address the burden of preventable deaths among children under-five in resource-constrained settings. The Tools for Integrated Management of Childhood Illness (TIMCI) project aims to support healthcare providers to identify and manage severe illness, whilst promoting resource stewardship, by introducing pulse oximetry and clinical decision support algorithms (CDSAs) to primary care facilities in I…
Sahel: La France dans une guerre multiforme
Ousmane NdiayeARTICLERevue Défense Nationale2021Cited by: 1
Le Sahel est confronté à une guerre multiforme où s’entrechoquent conflits intercommunautaires et lutte contre le djihadisme. La France est engagée dans cette complexité avec une divergence stratégique croissante entre Paris et ses partenaires sahéliens. Il est nécessaire de revoir la stratégie française dans cette région
Rainfall intensification in tropical semi-arid regions: The Sahelian case
Open AccessGérémy Panthou, Thierry Lebel et al.ARTICLEEnvironmental Research Letters2018
An anticipated consequence of ongoing global warming is the intensification of the rainfall regimes meaning longer dry spells and heavier precipitation when it rains, with potentially high hydrological and socio-economic impacts. The semi-arid regions of the intertropical band, such as the Sahel, are facing particularly serious challenges in this respect since their population is strongly vulnerable to extreme climatic events. Detecting long term…
A unifying view of climate change in the Sahel linking intra-seasonal, interannual and longer time scales
Open AccessAlessandra Giannini, Seyni Salack et al.ARTICLEEnvironmental Research Letters2013
We propose a re-interpretation of the oceanic influence on the climate of the African Sahel that is consistent across observations, 20th century simulations and 21st century projections, and that resolves the uncertainty in projections of precipitation change in this region: continued warming of the global tropical oceans increases the threshold for convection, potentially drying tropical land, but this ‘upped ante’ can be met if sufficient moist…
Comment les ménages d'une zone rurale du Sénégal gèrent-ils leurs ressources
Agnès Adjamagbo, Valerie Delaunay et al.ARTICLEÉtudes rurales2006Cited by: 4References: 3
Une étude menée à Niakhar, au Sénégal, montre que près de 50 % des ménages ne produisent pas suffisamment de céréales pour couvrir leurs besoins alimentaires. Le recours à la migration et à l'entraide familiale permet de compenser en grande partie ce déficit. Notre analyse révèle que certaines caractéristiques des ménages sont défavorables à la productivité : c'est le cas lorsqu'ils sont de grande taille, que le chef du ménage est une femme ou qu…
