ABSTRACT Multiple environmental cues have been shown to trigger biofilm detachment, the transition from surface-attached, highly organized communities known as biofilms motile lifestyle. The goal of this study was identify a gene product involved in sensing that dispersion Pseudomonas aeruginosa . To do so, we focused on novel putative chemotaxis transducer proteins could potentially be sensing. We identified locus encoding such protein played role indicated by observation an isogenic mutant...

Approximately 40% of children who experience an in-hospital cardiac arrest survive to hospital discharge. Achieving threshold intra-arrest diastolic blood pressure (BP) targets during cardiopulmonary resuscitation (CPR) and systolic BP after the return circulation may be associated with improved outcomes.To evaluate effectiveness a bundled intervention comprising physiologically focused CPR training at point care structured clinical event debriefings.A parallel, hybrid stepped-wedge, cluster...

Less than half of the thousands children who suffer in-hospital cardiac arrests annually survive, and neurologic injury is common among survivors. Hemodynamic-directed cardiopulmonary resuscitation improves short-term survival, but its impact on longer term survival mitochondrial respiration-a potential neurotherapeutic target-remains unknown. The primary objectives this study were to compare rates 24-hour with favorable outcome after arrest treated hemodynamic-directed versus standard...

Physiology-guided cardiopulmonary resuscitation (CPR) offers the potential to optimize and enable early prognosis. Physiology-Guided CPR was one of six focus topic for Wolf Creek XVII Conference held on June 14–17, 2023 in Ann Arbor, Michigan, USA. International thought leaders scientists field cardiac arrest from academia industry were invited. Participants submitted via online survey knowledge gaps, barriers translation research priorities each topic. Expert panels used results their own...

The association between chest compression (CC) pause duration and pediatric in-hospital cardiac arrest survival outcomes is unknown. American Heart Association has recommended minimizing pauses in CC children to <10 seconds, without supportive evidence. We hypothesized that longer maximum durations are associated with worse neurological outcomes.

Although advances in cardiopulmonary resuscitation have improved survival from cardiac arrest (CA), neurologic injury persists and impaired mitochondrial bioenergetics may be critical for targeted neuroresuscitation. The authors sought to determine if excellent postresuscitation care good traditional rates result persistently disordered cerebral a porcine pediatric model of asphyxia-associated ventricular fibrillation CA.After 7 minutes asphyxia, followed by fibrillation, 5 female...

Abstract Background Despite controversies, epinephrine remains a mainstay of cardiopulmonary resuscitation (CPR). Recent animal studies have suggested that may decrease cerebral blood flow (CBF) and oxygenation, possibly potentiating neurological injury during CPR. We investigated the cerebrovascular effects intravenous in swine model pediatric in-hospital cardiac arrest. The primary objectives this study were to determine if (1) doses significant acute effect on CBF tissue oxygenation CPR...
