ReviewIntegrated Feedforward and Feedback Mechanisms in Neurovascular Coupling.
Neurovascular coupling (NVC) is the mechanism that drives the neurovascular response to neural activation, and NVC dysfunction has been implicated in various neurologic diseases. NVC is driven by (1) nonmetabolic feedforward mechanisms that are mediated by various signaling pathways and (2) metabolic feedback mechanisms that involve metabolic factors. However, the interplay between these feedback and feedforward mechanisms remains unresolved. ⋯ Thus, feedback mechanisms ensure the brain milieu's stability when feedforward mechanisms are impaired. Our proposal integrates the feedforward and feedback mechanisms underlying NVC and suggests that these 2 mechanisms work like a fail-safe system, to a certain degree. We also discussed the difference between NVC and cerebral metabolic rate-CBF coupling and the clinical implications of our proposed framework.

Preoperative Multidisciplinary Team Huddle Improves Communication and Safety for Unscheduled Cesarean Deliveries: A System Redesign Using Improvement Science.
Optimal communication between care teams is a critical component in providing safe, timely, and appropriate patient care. Labor and delivery (L&D) units experience rapidly changing clinical scenarios often requiring escalation in care and unplanned cesarean deliveries (CDs). The University of Cincinnati Medical Center (UCMC) is a 550-bed academic level 4 maternal care center with a 13-bed L&D unit in Cincinnati, OH. There are approximately 2500 deliveries/y with a CD rate of 33%. The L&D unit is staffed with dedicated anesthesia personnel 24 hours a day. In our L&D unit, there was widespread dissatisfaction with multidisciplinary communication surrounding unscheduled CD. Near-miss safety events in our obstetric unit were attributed to preoperative communication failures. Initial surveys identified challenges in preoperative communication among nursing, anesthesiology, and obstetric teams leading to potential risk for compromised care. ⋯ In an academic obstetric unit, communication failures surrounding unscheduled CD were identified as a contributor to staff dissatisfaction and perception of safety risk. Implementation of a bedside multidisciplinary pre-CD huddle improved communication between teams and contributed to creating a culture of safety without causing significant delays in care.

Randomized Controlled Trial Multicenter StudySmallest Clinically Meaningful Improvement in Amputation-Related Pain and Brief Pain Inventory Scores as Defined by Patient Reports of Global Improvement After Cryoneurolysis: a Retrospective Analysis of a Randomized, Controlled Clinical Trial.
The smallest meaningful improvement in pain scores (minimal clinically important difference [MCID]) after an analgesic intervention is essential information when both interpreting published data and designing a clinical trial. However, limited information is available for patients with chronic pain conditions, and what is published is derived from studies involving pharmacologic and psychological interventions. We here calculate these values based on data collected from 144 participants of a previously published multicenter clinical trial investigating the effects of a single treatment with percutaneous cryoneurolysis. ⋯ Amputees with phantom limb pain treated with percutaneous cryoneurolysis rate analgesic improvements as clinically meaningful similar to pharmacologic treatments, although their MCID for the Brief Pain Inventory was somewhat larger than previously published values. This information on patient-defined clinically meaningful improvements will facilitate interpretation of available studies and guide future trial design.

Multicenter Study Comparative Study Observational StudyAssessing Full Stomach Prevalence with Ultrasound Following Preoperative Fasting in Diabetic Patients with Dysautonomia: A Comparative Observational Study.
Traditionally, diabetics have been considered patients with a high risk of aspiration due to having delayed gastric emptying; However, the evidence concerning residual gastric volume (GV) in fasting diabetic patients is inconsistent. This study aimed to compare the fasting GV of diabetic patients with or without dysautonomia with control patients scheduled for elective surgery using gastric ultrasound. ⋯ This study offers insights into the relationship between dysautonomia in patients with diabetes mellitus and the presence of full stomach, underscoring the significance of preoperative gastric ultrasound evaluation in managing perioperative risks in this population.
