INTRODUCTION (RAIR) Recto-anal inhibitory reflex is an integral part of normal defecation. The physiological characteristics of RAIR along anal length and anterior-posterior axis are unknown. AIM To perform topographic and vector-graphic evaluation of RAIR along anal canal using high definition manometry (HDM), and examine the role of various muscle components. METHODS Anorectal topography was assessed in 10 healthy volunteers using HDM probe with 256 sensors. RAIR data were analyzed every mm along the length of anal canal for topographic, baseline, residual, and plateau pressures during 5 mean volumes of balloon inflation (15cc, 40cc, 71cc, 101cc, 177cc), and in 3D by dividing anal canal into 4×2.1 mm grids. RESULTS Relaxation pressure progressively increases along anal canal with increasing balloon volume up to 71 cc and thereafter plateaus. In 3-D, RAIR is maximally seen at the middle and upper portions of anal canal (levels 1.2-3.2 cm) and posteriorly. Peak residual pressure was seen at proximal anal canal. CONCLUSION RAIR is characterized by differential anal relaxation along Anterior-Posterior axis, longitudinally along the length of anal canal, and it depends on the rectal distention volume. It is maximally seen at internal anal sphincter pressure zone. Multidimensional analyses indicate that external anal sphincter provides bulk of anal residual pressure. Our findings emphasize importance of sensor location and orientation; as anterior and more distal location may miss RAIR.

Overall, the literature supports beneficial pleotropic effects of statin use in contrast-induced nephropathy, head injury, Alzheimer's and Parkinson's disease, nuclear cataract, prostate cancer, infection management, and spinal cord injury. Further investigation is warranted, and randomized clinical trials are needed to confirm the clinical utility suggested by the reported studies included in this meta-analysis.

With the continuously changing health care environment and dramatic shift in patient demographics, institutions have the responsibility of identifying and dedicating resources for maintaining and improving wellness and resilience among front line providers to assure the quality of patient care. Our institution, the Ohio State University Wexner Medical Center (OSUWMC), has addressed the goal to decrease burnout for providers in a multistep, multiprofessional, and multiyear program starting firstly with institutional cultural change then focused provider interventions, and lastly, proactive resilience engagement. We describe herein our approach and outcomes as measured by provider wellness and health system outcomes. In addition, we address the overall feasibility and effectiveness of these programs in promoting provider compassion and mindfulness while reducing burnout and improving resilience. Institutional culture change and readiness were initiated in 2010 with the introduction of Crew Resource Management training for all providers across the OSUWMC. This multiyear program was implemented and has been sustained to the current day. Focused interventions to improve mindfulness were undertaken in the form of both Mindfulness in Motion (MIM) training for intensive care unit personnel and a “flipped classroom” mindfulness training for faculty and residents. Lastly, sustainable changes were introduced in the form of the Gabbe Health and Wellness program which consists of interprofessional MIM training and other wellness offerings for staff, faculty, and residents embedded across the entire medical center. The introduction of Crew Resource Management in 2010 continues to be endorsed and supported throughout OSUWMC for all providers, including residents and students. The improvements seen have not only improved patient satisfaction but also reduced patient safety events and improved national reputation for the institution as a whole. Subsequently, MIM training for intensive care unit providers has resulted in improved resilience as well as decreased patient safety events. In addition, the “flipped classroom” mindfulness training for residents and faculty has resulted in improvements in providing calm and compassionate care, improvements in physician wellbeing, and reductions in emotional exhaustion and depersonalization. Lastly, implementing the Gabbe Health and Wellness program inclusive of interprofessional MIM training for staff, faculty, and residents has resulted in significant reductions in burnout while significantly increasing resilience postintervention. The engagement from staff and enthusiasm to continue this program have escalated and been positively accepted across OSUWMC. To reduce the incidence of burnout, improve resilience, and ultimately improve patient outcomes, a health system must identify and prioritize a commitment and dedication of resources to develop and sustain a multimodal and interprofessional approach to change. These initiatives at OSU originated with cultural transformation allowing the acceptance of change in the form of mindfulness training, resilience building, and the engagement of organizational science, so as to demonstrate the outcomes and impact to the health system and academic peers. Herein we describe the work that has been done thus far, both published and in progress, to understand our journey.

Robotic cholecystectomy appears to be safe although costlier in comparison with laparoscopic cholecystectomy. Further studies are needed to understand the long-term implications of robotic technology, the cost to the health care system, and its role in minimally invasive surgery.
