Aims: To determine which patient and cardiac arrest factors were associated with obtaining neuroimaging after in-hospital cardiac arrest, and among those patients who had neuroimaging, factors associated with which neuroimaging modality was obtained.
Methods: Retrospective cohort study of patients who survived in-hospital cardiac arrest (IHCA) and were enrolled in the ICU-RESUS trial (NCT02837497).
Results: We tabulated ultrasound (US), CT, and MRI frequency within 7 days following IHCA and identified patient and cardiac arrest factors associated with neuroimaging modalities utilized.
Article Synopsis
- Viral lower respiratory tract infection (vLRTI) significantly impacts global child health, prompting research into the host immune responses using proteomics for better understanding and diagnosis.
- The study analyzed 1,305 proteins from tracheal aspirate and plasma of 62 critically ill children, finding 200 differentially expressed proteins that reveal key immune responses, with a robust nine-protein TA classifier showing high diagnostic accuracy (AUC of 0.96).
- It also highlighted the limited correlation between tracheal aspirate and plasma proteins and examined how viral load and bacterial co-infections influence immune signaling pathways.
Article Synopsis
- Viral lower respiratory tract infection (vLRTI) is a major cause of pediatric hospitalization and mortality globally, yet the immune responses involved are not well understood.
- A study analyzed over 1,300 proteins in tracheal aspirate and plasma from critically ill children, identifying significant protein changes linked to vLRTI and developing a diagnostic tool with high accuracy.
- Key findings included increased interferon and T cell responses in the lower airway, distinct protein profiles in plasma, and novel protein biomarkers that could enhance diagnostic approaches for severe vLRTI.
Importance: Patients with underlying cardiac disease form a considerable proportion of pediatric patients who experience in-hospital cardiac arrest. In pediatric patients after cardiac surgery, CPR with abdominal compressions alone (AC-CPR) may provide an alternative to standard chest compression CPR (S-CPR) with additional procedural and physiologic advantages.
Objective: Quantitatively describe hemodynamics during cardiopulmonary resuscitation (CPR) and outcomes of infants who received only abdominal compressions (AC-CPR).
Background: Sepsis-associated brain injury is associated with deterioration of mental status, persistent cognitive impairment, and morbidity. The SUR1/TRPM4 channel is a nonselective cation channel that is transcriptionally upregulated in the central nervous system with injury, allowing sodium influx, depolarization, cellular swelling, and secondary injury. We hypothesized that genetic variation in ABCC8 (SUR1 gene) and TRPM4 would associate with central nervous system dysfunction in severe pediatric sepsis.
