Advancing nutrition knowledge, skills, and attitudes in medical education and training: key themes and recommendations from the 2023 Summit.

The incorporation of comprehensive nutrition education into medical education and training is essential for equipping physicians with the knowledge and skills necessary to enhance patient health and outcomes. However, a deficiency in nutrition education persists in medical education, rendering physicians ill-prepared to address the vital role of nutrition in health and disease. This article summarizes the key themes and recommendations generated during the Summit on Medical Education in Nutrition, hosted in March 2023 by the Accreditation Council for Graduate Medical Education in collaboration with American Association of Colleges of Osteopathic Medicine and Association of American Medical Colleges.

Factors affecting minimally invasive surgery utilization during elective colectomies for diverticular disease in the United States.

Background: Compared with open surgery, minimally invasive surgery (MIS) has been shown to have improved outcomes when treating diverticular disease. This study aimed to analyze recent trends in MIS utilization for elective colectomy for diverticular disease and to identify individual variables and hospital characteristics associated with MIS utilization.

Methods: This population-based study examined individuals from the National Inpatient Sample who underwent elective colectomy for diverticular disease from 2016 to 2019.

Implementing High-Intensity, Trauma-Informed Sexual Risk Reduction in Women Involved in the Criminal Legal System.

Although research supports using brief or extended behavioral interventions to increase prevention of sexually transmitted infections (STIs), there is a shortage of current information about the specific effects on women in a short-stay carceral environment. This evidence-based practice implementation project aimed to employ the Safer Sex Efficacy (SSE) Workshop in a jail setting. A repeated measures design was used to compare STI knowledge acquisition and reports of condom use self-efficacy in a group of incarcerated women before, immediately after, and 3 weeks after participation in a high-intensity behavioral counseling intervention.

Closed-Incision and Surrounding Soft Tissue Negative Pressure Dressings in Post-Mastectomy Pre-Pectoral Direct-to-Implant Breast Reconstruction: A Pilot Study.

Closed-incision and surrounding soft tissue negative pressure therapy (cistNPT) is theorized to decrease infection, reduce tissue edema, and promote healing of the mastectomy skin flap. We report our early experience with this dressing in pre-pectoral direct-to-implant (pDTI) breast reconstruction. We retrospectively reviewed all patients who underwent post-mastectomy pDTI breast reconstruction with cistNPT between July 2019 and February 2020.

Outcomes of Margin Reexcision after Oncoplastic Breast Reduction.

Unlabelled: Tissue rearrangement after an oncoplastic breast reduction may complicate identification of margins during reexcision. Little is known about outcomes of reoperation in this setting.

Methods: This is a single-institution, retrospective analysis of outcomes of margin reexcisions after lumpectomy with concurrent oncoplastic Wise-pattern reduction from 2015 to 2020.

Hospital-Based Same-Day Compared to Overnight-Stay Mastectomy: An American College of Surgeons National Surgical Quality Improvement Program Analysis.

Enhanced Recovery after Surgery for mastectomy has resulted in increased use of outpatient same-day mastectomy (SDM). Whether SDM leads to increased readmissions or reoperations is not well documented. This study examines national data to compare outcomes of SDM to an overnight stay.

Rinse But Don't Repeat: Single Application V.A.C. VERAFLO Salvages Infected Breast Prostheses.

Introduction: Existing salvage protocols for infected breast prostheses using negative pressure wound therapy with instillation and dwell (NPWTi-d) require multiple returns to the operating room and prolonged length of stay. We present our expedited salvage protocol and discuss outcomes and associated costs savings.

Methods: Using a retrospective review, we identified 25 consecutive patients (27 breasts) with peri-prosthetic breast infection.

Is Sentinel Lymph Node Biopsy Reliable After Recent Oncoplastic Breast Reduction?

An oncoplastic breast reduction may disrupt normal lymphatic drainage and make subsequent identification of the sentinel lymph nodes (SLNs) unreliable. There are little data on the success rate of sentinel lymph node biopsy (SLNB) after recent oncoplastic breast reduction, and there is no agreement on whether SLNB should be done at the time of the partial mastectomy and reduction for ductal carcinoma in situ (DCIS). The primary goals of this study were to evaluate the identification rate of SLNB after recent oncoplastic or functional breast reduction and to examine recurrence rates in this setting.

Impacts of trait anxiety on visual working memory, as a function of task demand and situational stress.

Higher trait anxiety can impair cognitive functioning via attention, but relatively little is known about the impacts on visual working memory. These were investigated using previously validated visual feature binding tasks. In Study 1, participants' memory for visual features (shapes) and feature bindings (coloured shapes) was assessed.

Cost Utility of Breast Tissue Expansion using Carbon Dioxide versus Saline: An Analysis of Infection Risk.

Background: The AeroForm System, a needle-free, patient-controlled carbon dioxide-filled tissue expander, represents a novel option for tissue expansion in 2-stage breast reconstruction. This technology has previously been found to decrease time to expansion, health-care utilization, and infection rates. The purpose of this study was to determine the economic impact of the reduced infection rate observed with the AeroForm tissue expander as compared with saline tissue expansion.

Prospective Study Comparing Surgeons' Pain and Fatigue Associated with Nipple-Sparing versus Skin-Sparing Mastectomy.

Background: Nipple-sparing mastectomy (NSM) is more technically challenging than skin-sparing mastectomy (SSM) but offers quality-of-life and cosmetic advantages. However, surgeon physical symptoms related to NSM workload have not been documented.

Methods: This was a prospective study using questionnaires to compare surgeon-reported physical symptoms before, during, and after NSM versus SSM.

Intraoperative image updating for brain shift following dural opening.

OBJECTIVE Preoperative magnetic resonance images (pMR) are typically coregistered to provide intraoperative navigation, the accuracy of which can be significantly compromised by brain deformation. In this study, the authors generated updated MR images (uMR) in the operating room (OR) to compensate for brain shift due to dural opening, and evaluated the accuracy and computational efficiency of the process. METHODS In 20 open cranial neurosurgical cases, a pair of intraoperative stereovision (iSV) images was acquired after dural opening to reconstruct a 3D profile of the exposed cortical surface.

Sensorimotor Learning in a Computerized Athletic Training Battery.

Sensorimotor abilities are crucial for performance in athletic, military, and other occupational activities, and there is great interest in understanding learning in these skills. Here, behavioral performance was measured over three days as twenty-seven participants practiced multiple sessions on the Nike SPARQ Sensory Station (Nike, Inc., Beaverton, Oregon), a computerized visual and motor assessment battery.

The Economic Impact of Closed-Incision Negative-Pressure Therapy in High-Risk Abdominal Incisions: A Cost-Utility Analysis.

Background: Complex abdominal wall reconstruction is beset by postoperative complications. A recent meta-analysis comparing the use of closed-incision negative-pressure therapy to standard dressings found a statistically significant reduction in surgical-site infection. The use of closed-incision negative-pressure therapy is gaining acceptance in this population; however, the economic impact of this innovative dressing remains unknown.

Anthrax Toxin Receptor 1 Is Essential for Arteriogenesis in a Mouse Model of Hindlimb Ischemia.

Anthrax toxin receptor 1/tumor endothelial marker 8 (Antxr1 or TEM8) is up-regulated in tumor vasculature and serves as a receptor for anthrax toxin, but its physiologic function is unclear. The objective of this study was to evaluate the role of Antxr1 in arteriogenesis. The role of Antxr1 in arteriogenesis was tested by measuring gene expression and immunohistochemistry in a mouse model of hindlimb ischemia using wild-type and ANTXR1(-/-) mice.

Porcine acellular dermal matrix (PADM) vascularises after exposure in open necrotic wounds seen after complex hernia repair.

Biological alternatives to synthetic meshes are increasingly utilised in complex abdominal wall reconstruction. There is a lack of evidence demonstrating that non-cross-linked porcine acellular dermal matrix vascularizes and integrates with human tissue in suboptimal wound conditions. We aimed to evaluate these properties in Strattice™ (Life Cell Inc.

Utility of indocyanine green fluorescence lymphography in identifying the source of persistent groin lymphorrhea.

Surgical manipulation of the groin can result in lymphatic injury in a significant number of patients leading to poor wound healing or infectious complications. Surgical repair of lymphatic injury is greatly aided by the precise and prompt intraoperative localization of the injured lymphatic vessels. We assessed and identified lymphatic leaks in 2 cases of surgical wound lymphorrhea occurring after instrumentation of the groin using laser-assisted indocyanine green lymphography paired with isosulfan blue injection.

A modified approach to component separation using biologic graft as a load-sharing onlay reinforcement for the repair of complex ventral hernia.

Background: Components separation has been proposed as a means to close large ventral hernia without undue tension. We report a modification on open components separation that allows for the incorporation of onlaid noncrosslinked porcine acellular dermal matrix (Strattice, LifeCell Corp, Branchburg, NJ) as a load-sharing structure.

Methods: This was a retrospective case series including all cases using Strattice from July 2008 through December 2009.

Massive localized lymphedema revisited: a quickly rising complication of the obesity epidemic.

Massive localized lymphedema (MLL) is a rising and potentially fatal complication of the obesity epidemic. Described as a benign lymphoproliferative overgrowth of obese patients, MLL is a form of secondary lymphedema, caused by the obstruction of lymphatic flow, with characteristic clinical and histological presentation. Patients have a large mass with classic skin changes often accompanied by lymphatic weeping that require complex reconstruction.

Comparison of 3 techniques of fat grafting and cell-supplemented lipotransfer in athymic rats: a pilot study.

Background: Given the wide application of autologous fat grafting, a new emphasis on fat processing techniques has emerged in an effort to limit unpredictable degrees of resorption often seen with this procedure. With the growing interest in regenerative medicine, approaches to supplement fat grafts with adipose-derived stem cells are evolving in hopes of promoting vascularization and neoadipogenesis.

Objective: The authors evaluated the outcomes of the most common processing techniques for fat grafting--decantation, washing, high-speed centrifugation--and stromal vascular cell-supplemented lipotransfer to determine which method yields a higher percentage of retention and better quality graft.

Exercise training-induced adaptations associated with increases in skeletal muscle glycogen content.

Chronic exercise training results in numerous skeletal muscle adaptations, including increases in insulin sensitivity and glycogen content. To understand the mechanism leading to increased muscle glycogen, we studied the effects of exercise training on glycogen regulatory proteins in rat skeletal muscle. Female Sprague Dawley rats performed voluntary wheel running for 1, 4 or 7 weeks.

Effects of systemic tadalafil on skin flap survival in rats.

Objective: Phosphodiesterase-5 inhibitors, used to increase penile blood flow in erectile dysfunction patients, have recently been postulated to increase blood flow and flap survival in cutaneous flaps based on random blood supply. This study aims to investigate the phosphodiesterase-5 inhibitor tadalafil, administered orally, on random flap survival.

Methods: Modified McFarlane flaps measuring 8 cm × 2.
