Given the high rates of physical trauma and pain among service members, opioid-prescribing practices and use patterns have significant implications for the well-being of service members and can affect military medicine and personnel readiness. This study measured the association between prescribed opioid and benzodiazepine medications and subsequently reported injuries (accidental, alcohol and drug related, self-inflicted, and violence related) among active duty military members. Participants were service members who entered the military between January 1, 2005, and June 30, 2010. ⋯ Although a dose-response effect was observed for all injury types, it reached a plateau sooner for natural or environmental accidents and self-inflicted injuries relative to alcohol-related and drug-related injuries, violence-related injuries, vehicle accidents, accidental falls, and other accidents. Benzodiazepine prescriptions were found in 3.5% of individuals with an injury and 0.5% of individuals without an injury. The association between benzodiazepine prescriptions and injuries was strongest for natural and environmental accidents.

Cerebellopontine angle (CPA) meningiomas present challenges given their proximity to neurovascular structures. Postoperative complications and persistent symptoms can debilitate patients, and our ability to predict recovery course remains variable. Here, we examine the presentation, management, and outcomes of patients with CPA meningiomas. ⋯ GTR remains critical to achieve optimal symptom control and reduce progression/recurrence rates for CPA meningiomas. Drilling the IAC is an important predictor of GTR in tumors with intracanalicular invasion.

Racial and Ethnic Concordance Between the Patient and Anesthesia Team and Patients' Satisfaction With Pain Management During Cesarean Delivery.
Racial and ethnic concordance between patients and health care providers increases patient satisfaction but has not been examined in obstetric anesthesia care. This study evaluated the association between racial and ethnic concordance and satisfaction with management of pain during cesarean delivery (PDCD). ⋯ Our inability to identify an association between concordance and satisfaction is likely due to the high satisfaction rate in our cohort (78.2%), combined with low proportion of full concordance (4.5%). Addressing elements such as PDCD, anxiety, intravenous medication administration, and use of epidural anesthesia for cesarean delivery, and a better understanding of the interplay between concordance and satisfaction are warranted.

As a mechanosensitive cation channel and key regulator of vascular barrier function, endothelial transient receptor potential vanilloid type 4 (TRPV4) contributes critically to ventilator-induced lung injury and edema formation. Ca2+ influx via TRPV4 can activate Ca2+-activated potassium (KCa) channels, categorized into small (SK1-3), intermediate (IK1), and big (BK) KCa, which may in turn amplify Ca2+ influx by increasing the electrochemical Ca2+ gradient and thus promote lung injury. The authors therefore hypothesized that endothelial KCa channels may contribute to the progression of TRPV4-mediated ventilator-induced lung injury. ⋯ KCa channels, specifically IK1, act as amplifiers of TRPV4-mediated Ca2+ influx and establish a detrimental feedback that promotes barrier failure and drives the progression of ventilator-induced lung injury.
