Full esophageal mobilization during hiatal hernia repair with concomitant sleeve gastrectomy improves postoperative reflux symptoms for patients with preexisting reflux.

Background: Hiatal hernia repair (HHR) performed concurrently with vertical sleeve gastrectomy (VSG) has been shown to improve postoperative gastroesophageal reflux disease (GERD). However, data on the optimal extent of esophageal mobilization during repair are lacking. Mobilization techniques for HHR during VSG include partial (PM) or full (FM) mobilization of the esophagus.

Achieving durable compliance with venous thromboembolism prophylaxis in bariatric surgery: 3-year data from a major academic medical center.

Background: Metabolic and bariatric surgery (MBS) venous thromboembolism (VTE) prescribing practices vary widely. Our institutional VTE prophylaxis protocol has historically been unstandardized.

Objectives: To create a standardized MBS VTE prophylaxis protocol, track protocol compliance, and identify barriers to protocol compliance and address them with Plan-Do-Study-Act (PDSA) cycles.

The financial impact of the COVID-19 pandemic on sleeve gastrectomy at a major academic institution.

Introduction: The COVID-19- pandemic significantly impacted metabolic and bariatric surgery (MBS) practices due to large-scale surgery cancellations along with staff and supply shortages. We analyzed sleeve gastrectomy (SG) hospital-level financial metrics before and after the COVID-19 pandemic.

Methods: Hospital cost-accounting software (MicroStrategy, Tysons, VA) was reviewed for revenues, costs, and profits per SG at an academic hospital (2017-2022).

Parental experiences related to pediatric and adolescent chronic non-cancer pain: A qualitative exploration.

Purpose: To explore parental experiences in personal functioning and parenting associated with having a child experiencing chronic non-cancer pain.

Methods: Parents with children experiencing chronic pain were asked to fill out a survey prior to their initial Pediatric Pain Clinic or Pain Psychology appointment at a children's hospital in the southeastern United States. A retrospective analysis of qualitative data was conducted.

Intramuscular versus intradermal administration for influenza vaccination in college students: A pilot study.

College student populations are considered at greater risk of contracting influenza due to their close living conditions. Despite this increased risk, college students are reluctant to obtain annual vaccination. This pilot study sought to determine perceptions of students on a college campus who received the annual influenza vaccination via an intradermal route.

Insect reproductive behaviors are important mediators of carrion nutrient release into soil.

Current declines in terrestrial insect biomass and abundance have raised global concern for the fate of insects and the ecosystem services they provide. However, the ecological and economic contributions of many insects have yet to be quantified. Carrion-specializing invertebrates are important mediators of carrion decomposition; however, the role of their reproductive activities in facilitating this nutrient pulse into ecosystems is poorly understood.

A Call for Data-Driven Networks to Address Equity in the Context of Undergraduate Biology.

National efforts to improve equitable teaching practices in biology education have led to an increase in research on the barriers to student participation and performance, as well as solutions for overcoming these barriers. Fewer studies have examined the extent to which the resulting data trends and effective strategies are generalizable across multiple contexts or are specific to individual classrooms, institutions, or geographic regions. To address gaps in our understanding, as well as to establish baseline information about students across contexts, a working group associated with a research coordination network (Equity and Diversity in Undergraduate STEM, EDU-STEM) convened in Las Vegas, Nevada, in November of 2019.

Spatiotemporal niche partitioning in a specious silphid community (Coleoptera: Silphidae Nicrophorus).

Resource niche partitioning mediates the coexistence of similar species by reducing the chance of competitive encounters. For co-occurring species that share an ephemeral resource, contrasting activity in space and time may facilitate their persistence. Burying beetles (Silphidae: Nicrophorus) depend entirely on small vertebrate carcasses to reproduce.

Inhibition of microorganisms on a carrion breeding resource: the antimicrobial peptide activity of burying beetle (Coleoptera: Silphidae) oral and anal secretions.

Competition between scavengers and microorganisms for the nutrients within carrion is well documented. As a significant contributor to food web energetics, carrion serves not only as a food source for scavengers, but also as a reproductive resource for many insects. One example are the burying beetles of the Nicrophorus genus (Coleoptera: Silphidae) whose reproduction is dependent on locating and successfully sequestering vertebrate carrion.

Innate immune response after resuscitation with hemoglobin-based oxygen carrier and recombinant factor VIIA in uncontrolled hemorrhagic shock in a swine model.

Background: Rapid resuscitation with oxygen-carrying fluids is critically important in hemorrhagic shock (HS) combat casualties in remote areas where blood is not available. Hemoglobin-based oxygen carrier-201 (HBOC-201) has been shown to increase survival and reduce immune activation following HS in animal models. Recombinant factor VIIa (rfVIIa), a systemic hemostatic agent, is Food and Drug Administration approved for use in acute hemorrhage in hemophilic patients.

Vasoactivity of bovine polymerized hemoglobin (HBOC-201) in swine with traumatic hemorrhagic shock with and without brain injury.

Background: We previously reported that bovine polymerized hemoglobin (HBOC- 201) improved outcome in swine with hemorrhagic shock (HS) with and without traumatic brain injury (TBI). Herein, we add analyses of blood pressure (BP) responses, associated physiologic data, and HS fluid infusion guidelines.

Methods: HBOC-201 versus standard fluid resuscitation was compared in four anesthetized invasively monitored swine models: moderate controlled HS, severe controlled HS, severe uncontrolled HS (liver injury), and severe uncontrolled HS/TBI (liver/parietal brain injuries).

Immune effects of resuscitation with HBOC-201, a hemoglobin-based oxygen carrier, in swine with moderately severe hemorrhagic shock from controlled hemorrhage.

HBOC-201, a hemoglobin-based oxygen carrier, improved physiologic parameters and survival in hemorrhagic shock (HS) animal models. However, resuscitation from HS and the properties of different fluids influence immune responses. The aim of this study was to determine if HBOC-201 significantly alters immune function in traumatic HS.
