This study was to investigate the role of Nrf2/ARE signaling pathway in the pleiotropic neuroprotective effect of progesterone (PROG) on traumatic brain injury (TBI). ⋯ PROG reduced cerebral edema, apoptosis, inflammatory reaction, and intracellular calcium ion overload effects after TBI. These beneficial effects were not seen in the Nrf2-/- mouse model of TBI. The results from this study suggested that the Nrf2/ARE signal pathway may be involved in the pleiotropic neuroprotective effect of PROG on TBI.

Review Meta Analysis
Effect of Early Versus Late Tracheostomy or Prolonged Intubation in Critically Ill Patients with Acute Brain Injury: A Systematic Review and Meta-Analysis.
The optimal timing of tracheostomy placement in acutely brain-injured patients, who generally require endotracheal intubation for airway protection rather than respiratory failure, remains uncertain. We systematically reviewed trials comparing early tracheostomy to late tracheostomy or prolonged intubation in these patients. ⋯ Performing an early tracheostomy in acutely brain-injured patients may reduce long-term mortality, duration of mechanical ventilation, and ICU length of stay. However, waiting longer leads to fewer tracheostomy procedures and similar short-term mortality. Future research to explore the optimal timing of tracheostomy in this patient population should focus on patient-centered outcomes including patient comfort, functional outcomes, and long-term mortality.
