Experimental medicine study with stabilised native-like HIV-1 Env immunogens drives long-term antibody responses, but lacks neutralising breadth.

Background: We report findings from an experimental medicine study of rationally designed prefusion stabilised native-like HIV envelope glycoprotein (Env) immunogens, representative of global circulating strains, delivered by sequential intramuscular injection.
Methods: Healthy adult volunteers were enrolled into one of five groups (A to E) each receiving a different schedule of one of two consensus Env immunogens (ConM SOSIP, ConS UFO, either unmodified or stabilised by chemical cross-linking, followed by a boost with two mosaic Env immunogens (Mos3.1 and Mos3.
Background: Diarrhoeal diseases claim more than 1 million lives annually and are a leading cause of death in children younger than 5 years. Comprehensive global estimates of the diarrhoeal disease burden for specific age groups of children younger than 5 years are scarce, and the burden in children older than 5 years and in adults is also understudied. We used results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021 to assess the burden of, and trends in, diarrhoeal diseases overall and attributable to 13 pathogens, as well as the contributions of associated risk factors, in children and adults in 204 countries and territories from 1990 to 2021.

- The World Health Assembly set six global nutrition targets (GNTs) in 2012 to improve maternal and child health, but there has been no comprehensive report detailing progress from 2012 to 2021.
- A study evaluated the prevalence and impact of these nutrition targets across 204 countries using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 and projected future trends up to 2050.
- By 2021, only a few countries met some GNTs; most showed increased child overweight and notable decreases in female anaemia, highlighting a connection between societal development status and nutritional challenges.
Clinical research framework proposal for ketogenic metabolic therapy in glioblastoma.

Article Synopsis
- Glioblastoma (GBM) is the deadliest brain tumor in adults, and current therapies are largely ineffective, which drives the need for new treatment strategies based on the tumor's metabolic needs, specifically glucose and glutamine.
- A ketogenic metabolic therapy (KMT) approach targets these metabolic pathways by combining dietary changes with specific drugs to limit glycolysis and glutaminolysis, while promoting the use of non-fermentable fuels like ketones and fatty acids.
- The glucose-ketone index (GKI) serves as a biomarker to monitor treatment effectiveness, aiming to create a more hostile environment for tumor growth and improve outcomes in GBM as well as potentially other cancer types reliant on similar metabolic pathways.
