Some Brain Regions Are Abnormally Small in People With PWS: Study

Certain regions of the brain are unusually small in people with Prader-Willi syndrome (PWS), a study reveals. “The present study provides objective evidence of volumetric alterations in the subcortical, limbic, and brainstem structures in individuals with PWS,” its researchers wrote. The study, “Differential volume reductions in…

Europe Awaits Proposed New Framework for Sharing Health Data

The European Commission is expected to propose a new governing framework for health data next month, called the European Health Data Space (EHDS), with the aim of connecting national health systems to facilitate secure and efficient transfer of data across systems in different European nations.

Hunger-regulating Hormone Levels Found to Be Abnormal in PWS

Levels of several hunger-regulating hormones are dysregulated in people with Prader-Willi syndrome (PWS), which likely contributes to the excessive hunger that characterizes the condition, a study suggests. Clustering patients based on these hormone levels could help to detect PWS and identify targets for therapies, researchers say. The study, “…

Study: Low-cost MS-QMA Feasible for Newborn Screening of PWS

A low-cost screening test called methylation-specific quantitative melt analysis (MS-QMA) could feasibly be used to conduct newborn screening for Prader-Willi syndrome (PWS) and related conditions, according to a new study. The study, “Feasibility of Screening for Chromosome 15 Imprinting Disorders in 16579 Newborns by Using a…
