HOCUS POCUS: ultrasound beyond regional anesthesia in the ambulatory setting.
Application of ultrasound in clinical anesthesia practice extends beyond regional anesthesia. In this review, we have discussed other point of care applications of ultrasound in perioperative care and anesthetic management with special emphasis on ambulatory practice. ⋯ Perioperative POCUS skill is a natural extension of ultrasound guided regional anesthesia. Utilizing POCUS in the perioperative period would accelerate the level of appropriate care, safety and improve outcomes in ambulatory centers. More anesthesiologists embracing POCUS would enhance patient care in a timely fashion at the ambulatory centers. POCUS in ambulatory practice can be valuable in avoiding delay or cancellation of surgeries and improving patient satisfaction.

ReviewThe role of renin-angiotensin system in sepsis-associated acute kidney injury: mechanisms and therapeutic implications.
This review aims to explore the relationship between the renin angiotensin system (RAS) and sepsis-associated acute kidney injury (SA-AKI), a common complication in critically ill patients associated with mortality, morbidity, and long-term cardiovascular complications. Additionally, this review aims to identify potential therapeutic approaches to intervene with the RAS and prevent the development of AKI. ⋯ SA-AKI is a common condition that can involve disturbances in the RAS, particularly the canonical angiotensin-converting enzyme (ACE) angiotensin-II (Ang II)/angiotensin II receptor 1 (AT-1R) axis. Increased renin levels, a key enzyme in the RAS, have been shown to be associated with AKI and may also guide vasopressor therapy in shock. In patients with high renin levels, angiotensin II administration may reduce renin concentration, improve intra-renal hemodynamics, and enhance signaling through the angiotensin II receptor 1. Further studies are needed to explore the role of the RAS in SA-AKI and the potential for targeted therapies.

Labor neuraxial analgesia may reduce the odds of postpartum hemorrhage, the leading indication for maternal blood transfusion during childbirth. This study tested the hypothesis that labor neuraxial analgesia is associated with reduced odds of maternal blood transfusion overall. ⋯ Labor neuraxial analgesia may be associated with reduced odds of maternal blood transfusion in intrapartum cesarean deliveries and, to a lesser extent, vaginal deliveries. The specific effect size varies widely by delivery mode and is unclear given the poor sensitivity of the data set for the maternal transfusion primary outcome.

Observational StudyIdentification of Clinically Significant Cytokine Signature Clusters in Patients With Septic Shock.
To identify cytokine signature clusters in patients with septic shock. ⋯ Longitudinal measurement of cytokine profiles at initiation of vasoactive medications and 24 hours later revealed three distinct cytokine signature clusters that correlated with clinical outcomes.

Brain-predicted age difference estimated using DeepBrainNet is significantly associated with pain and function-a multi-institutional and multiscanner study.
Brain age predicted differences (brain-PAD: predicted brain age minus chronological age) have been reported to be significantly larger for individuals with chronic pain compared with those without. However, a debate remains after one article showed no significant differences. Using Gaussian Process Regression, an article provides evidence that these negative results might owe to the use of mixed samples by reporting a differential effect of chronic pain on brain-PAD across pain types. ⋯ Moreover, brain-PAD was significantly related to multiple variables underlying the multidimensional pain experience. This comprehensive work adds evidence of pain type-specific effects of chronic pain on brain age. This could help in the clarification of the debate around possible relationships between brain aging mechanisms and pain.
