Kisspeptin is elevated in the brain after intracerebral haemorrhagic stroke.

Intracerebral haemorrhage (ICH) is the most severe subtype of stroke, with a 2-year mortality of nearly 50% and the greatest rate of disability amongst stroke survivors. Whilst treatment options for ICH remain limited, the condition requires prompt identification and rapid intervention to reduce permanent brain damage, with diagnosis traditionally confirmed by CT imaging. Although imaging is excellent at determining the presence of an intracranial bleed, biomarkers may help to identify the type of stroke or when the stroke began.

Longer-term survival, quality of life, and cost-effectiveness of conservative versus liberal oxygenation targets in critically ill children: a pre-specified analysis from Oxy-PICU, a multicentre, open, parallel-group, randomised controlled trial.

Background: Peripheral oxygen saturation (SpO) above 94% is typical in children in paediatric intensive critical care units (PICUs) who are receiving invasive ventilation and supplemental oxygen. In a previous report from the Oxy-PICU trial, we showed that lower (conservative) oxygenation targets (SpO 88-92%) are beneficial, showing small but statistically significant differences in duration of organ support and large but non-significant cost reductions at 30 days. In this pre-specified analysis of the Oxy-PICU trial, we compare longer-term outcomes and cost-effectiveness of conservative versus liberal (SpO >94%) oxygenation targets in children with emergency PICU admission.

The implementation of infant pain practice change resource to improve infant procedural pain practices: a hybrid type 1 effectiveness-implementation study.

Implementation of infant pain practice change (ImPaC) is a multifaceted web-based resource to support pain practice change in neonatal intensive care unit (NICU). We evaluated the (1) intervention effectiveness and (2) implementation effectiveness of ImPaC using a hybrid type 1 effectiveness-implementation study (ie, cluster randomized controlled trial and longitudinal descriptive study). Eligible level 2 and 3 Canadian NICUs were randomized to intervention (INT) or waitlisted to usual care (UC) for 6 months.
