Anemia prevalence in women of reproductive age in low- and middle-income countries between 2000 and 2018

Geospatial estimates of the prevalence of anemia in women of reproductive age across 82 low-income and middle-income countries reveals considerable heterogeneity and inequality at national and subnational levels, with few countries on track to meet the WHO Global Nutrition Targets by 2030.

Characterising acute and chronic care needs: insights from the Global Burden of Disease Study 2019

Chronic care manages long-term, progressive conditions, while acute care handles short-term ones. Here, authors show chronic conditions account for most of the global health burden, with 68% of DALYs and 93% of YLDs attributed to chronic care needs.

Mapping local patterns of childhood overweight and wasting in low- and middle-income countries between 2000 and 2017

Fine-scale geospatial mapping of overweight and wasting (two components of the double burden of malnutrition) in 105 LMICs shows that overweight has increased from 5.2% in 2000 to 6.0% in children under 5 in 2017. Although overall wasting decreased over the same period, most countries are not on track to meet the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025.

New Egyptian sauropod reveals Late Cretaceous dinosaur dispersal between Europe and Africa

A new titanosaurian sauropod, Mansourasaurus, is the most complete terrestrial vertebrate from the post-Cenomanian Cretaceous of the African mainland. Phylogenetic analyses reveal the existence of a titanosaurian clade inhabiting both Africa and Europe at this time and a faunal connection between the two continents.
