A model of occupational stress to assess impact of COVID-19 on critical care and redeployed nurses: a mixed-methods study.

Objective: To use the job demands-resources model of occupational stress to quantify and explain the impact of working in critical care during the COVID-19 pandemic on nurses and their employing organisation.

Design: Two-phase mixed methods: a cross-sectional survey (January 2021-March 2022), with comparator baseline data from April to October 2018 (critical care nurses only), and semistructured interviews.

Participants: Critical care nurses ( = 461) and nurses redeployed to critical care ( = 200) who worked in the United Kingdom National Health Service (primarily Scotland) between January 2021 and March 2022.

Ceramide lowering rescues respiratory defects in a Drosophila model of acid sphingomyelinase deficiency.

Types A and B Niemann-Pick disease (NPD) are inherited multisystem lysosomal storage disorders due to mutations in the SMPD1 gene. Respiratory dysfunction is a key hallmark of NPD, yet the mechanism for this is underexplored. SMPD1 encodes acid sphingomyelinase (ASM), which hydrolyses sphingomyelin to ceramide and phosphocholine.

Quantifying myelin density in the feline auditory cortex.

The cerebral cortex comprises many distinct regions that differ in structure, function, and patterns of connectivity. Current approaches to parcellating these regions often take advantage of functional neuroimaging approaches that can identify regions involved in a particular process with reasonable spatial resolution. However, neuroanatomical biomarkers are also very useful in identifying distinct cortical regions either in addition to, or in place of functional measures.
