Students', parents' and teachers' perspectives on comprehensive school-based sleep promotion.

Objective: Sleep deprivation is common among children and schools are ideal settings in which to influence children's sleep. Children spend a significant amount of time at school during key developmental periods, and programmes that influence students' well-being also benefit academic achievement. Comprehensive School Health (CSH) is an approach that prioritises school, home and community partnerships by supporting the development of health behaviours.

Synthetic Siglec-9 Agonists Inhibit Neutrophil Activation Associated with COVID-19.

Severe cases of coronavirus disease 2019 (COVID-19), caused by infection with SARS-CoV-2, are characterized by a hyperinflammatory immune response that leads to numerous complications. Production of proinflammatory neutrophil extracellular traps (NETs) has been suggested to be a key factor in inducing a hyperinflammatory signaling cascade, allegedly causing both pulmonary tissue damage and peripheral inflammation. Accordingly, therapeutic blockage of neutrophil activation and NETosis, the cell death pathway accompanying NET formation, could limit respiratory damage and death from severe COVID-19.

Peripheral TREM1 responses to brain and intestinal immunogens amplify stroke severity.

Stroke is a multiphasic process in which initial cerebral ischemia is followed by secondary injury from immune responses to ischemic brain components. Here we demonstrate that peripheral CD11bCD45 myeloid cells magnify stroke injury via activation of triggering receptor expressed on myeloid cells 1 (TREM1), an amplifier of proinflammatory innate immune responses. TREM1 was induced within hours after stroke peripherally in CD11bCD45 cells trafficking to ischemic brain.
