Heart Rate Variability as a Prognostic Tool for Gastroschisis Infants in the Neonatal Intensive Critical Unit.

OBJECTIVE: Gastroschisis is the most common congenital abdominal wall defect, with an increasing incidence. It results in extrusion of abdominal contents with associated delayed intestinal motility. Abnormal heart rate characteristics (HRCs) such as decreased variability occur due to the inflammatory response to sepsis in preterm infants. This study aimed to test the hypothesis that infants with gastroschisis have decreased heart rate variability (HRV) after birth and that this physiomarker may predict outcomes. STUDY DESIGN: We analyzed heart rate data from and clinical variables for all infants admitted with gastroschisis from 2009 to 2020. RESULTS: Forty-seven infants were admitted during the study period and had available data. Complex gastroschisis infants had reduced HRV after birth. For those with sepsis and necrotizing enterocolitis, abnormal HRCs occurred early in the course of illness. CONCLUSION: Decreased HRV was associated with complex gastroschisis. Infants in this group experienced complications that prolonged time to full enteral feeding and time on total parenteral nutrition. KEY POINTS: · Infants with gastroschisis can be classified into two subcategories, simple and complex disease.. · Those with complex disease often require prolonged stays in the neonatal intensive care unit and costly hospitalizations. We hypothesized that infants with complex gastroschisis are more likely to have abnormal HRC due to intestinal inflammation.. · In this study, we identified associations between abnormal HRV, heart rate characteristicHRC, and the development of gastroschisis complications. Additionally, we described differences in clinical characteristics between infants with complex versus simple gastroschisis..

A novel method for culturing enteric neurons generates neurospheres containing functional myenteric neuronal subtypes.

BACKGROUND: The enteric nervous system (ENS) is comprised of neurons, glia, and neural progenitor cells that regulate essential gastrointestinal functions. Advances in high-efficiency enteric neuron culture would facilitate discoveries surrounding ENS regulatory processes, pathophysiology, and therapeutics. NEW METHOD: Development of a simple, robust, one-step method to culture murine enteric neurospheres in a 3D matrix that supports neural growth and differentiation. RESULTS: Myenteric plexus cells isolated from the entire length of adult murine small intestine formed ≥3000 neurospheres within 7 days. Matrigel-embedded neurospheres exhibited abundant neural stem and progenitor cells expressing Sox2, Sox10 and Msi1 by day 4. By day 5, neural progenitor cell marker Nestin appeared in the periphery of neurospheres prior to differentiation. Neurospheres produced extensive neurons and neurites, confirmed by Tubulin beta III, PGP9.5, HuD/C, and NeuN immunofluorescence, including neural subtypes Calretinin, ChAT, and nNOS following 8 days of differentiation. Individual neurons within and external to neurospheres generated depolarization induced action potentials which were inhibited in the presence of sodium channel blocker, Tetrodotoxin. Differentiated neurospheres also contained a limited number of glia and endothelial cells. COMPARISON WITH EXISTING METHODS: This novel one-step neurosphere growth and differentiation culture system, in 3D format (in the presence of GDNF, EGF, and FGF2), allows for ∼2-fold increase in neurosphere count in the derivation of enteric neurons with measurable action potentials. CONCLUSION: Our method describes a novel, robust 3D culture of electrophysiologically active enteric neurons from adult myenteric neural stem and progenitor cells.

Post-operative Opioid Reduction Protocol Reduces Racial Disparity in Clinical Outcomes in Children.

INTRODUCTION: Racial disparities in health outcomes continue to exist for children requiring surgery. Previous investigations suggest that clinical protocols may reduce racial disparities. A post-operative opioid reduction protocol was implemented in children undergoing abdominal surgery who were less than 1 years old at a tertiary level hospital. The purpose of this investigation was to determine if the clinical protocol was associated with a reduction in racial disparity in post-operative opioid prescribing patterns and associated clinical outcomes. METHODS: A post-operative opioid reduction protocol based on standing intravenous acetaminophen, educational sessions with nursing staff, and standardized post-operative sign-out between the surgical and NICU teams was implemented in children under 1 year old in 2016. A time series and before and after analysis was conducted using a historical pre-intervention cohort (Jan 2011-Dec 2015) and prospectively collected post-intervention cohort (Jan 2016-Jan 2021). Primary outcomes included post-operative opioid use and post-operative pain scores stratified by race. Secondary outcomes included associated clinical outcomes also stratified by race. RESULTS: A total of 249 children were included in the investigation, 117 in the pre-intervention group and 132 in the post intervention group. The majority of patients in both cohorts were either White or Black. The two cohorts were equally matched in terms of pre-operative clinical variables. In the pre-intervention cohort, the median post-operative morphine equivalents in White children was 2.1 mg/kg (IQR 0.2, 11.1) while in Black children it was 13.1 mg/kg (IQR 2.4, 65.3), p-value = 0.0352. In the post-intervention cohort, the median value for White children and Black children was statistically identical (0.05 mg/kg (IQR 0, 0.5) and 0.0 mg/kg (IQR 0, 0.3), respectively, p-value = 0.237). This pattern was also demonstrated in clinical variables including length of stay, intubation length and total parenteral nutrition use. In the pre-intervention cohort, the total length of stay for white children was 16 days while for black children it was 45 days (p = 0.007). In the postintervention cohort the length of stay for both White and Black children were identical at 8 days (p = 0.748). CONCLUSION: The use of a clinical opioid reduction protocol implemented at a tertiary medical center was associated with a reduction in racial disparity in opioid prescribing habits in children. Prior to the protocol, there was a racial disparity in clinical variables associated with prolonged opioid use including length of stay, TPN use, and intubation length. The clinical protocol reduced variability in opioid prescribing patterns in all racial groups which was associated with a reduction in variability in associated clinical variables. LEVEL OF EVIDENCE: Level III.

How I Do It: Suicidal Ideation During Surgical Training: Is an Innovative Surgical Trainee Check Ins Program a Part of the Solution?

OBJECTIVE: Mental health distress and suicidal ideation are leading contributors to the silent epidemic of physician suicide leading to approximately 300 to 400 physician deaths per year. The Second Trial has illuminated the alarming fact that several of our residents have experienced suicidal thoughts within the last year. Unfortunately, our institution is not an outlier. Suicidal ideation and under- or untreated mental health disorders are increasingly prevalent in the surgical trainee population. Given the major concern for our residents' well-being, our department consulted a licensed mental health professional familiar with resident training and the GME to develop a program to provide access to a mental health professional that is free of cost for trainees, safe and confidential. DESIGN: Implementation of a 30 minute opt-out resident check-in program with a licensed mental health professional and a post-session survey that provided retrospective survey data for analysis. SETTING: This program was implemented at the University of Virginia Health System in Charlottesville, VA. PARTICIPANTS: General surgery categorical and preliminary residents participated in this program. RESULTS: Thirty residents participated in the program and an overwhelming majority would like to continue this program at regular intervals. Sessions were 25 minutes on average and 27.7% of participants requested additional sessions. CONCLUSIONS: Implementation of this program for our surgical trainees was favorably perceived with request for continuation of the program and provided access to a safe space with a familiar provider.

Family satisfaction in the trauma and surgical intensive care unit: another important quality measure.

BACKGROUND: A growing body of research has explored patient satisfaction as one of the healthcare quality measures. To date, scarce data are available regarding family experience in the trauma and surgical intensive care unit (TSICU). The purpose of this study was to describe and analyze the results of a family satisfaction survey in the TSICU. METHODS: Family members of patients at a level 1 trauma center were invited to participate in this study after 72 hours of intensive care unit stay. Participants completed a modified version of the Family Satisfaction in the Intensive Care Unit questionnaire, a validated survey measuring family satisfaction with care and decision-making. Data collection spanned from April 2016 to July 2017. Patient characteristics were compiled from the medical record. Quantitative analysis was performed using a 5-point Likert score, converted to a scale of 0 (poor) to 100 (excellent). RESULTS: The overall response rate was 78.6%. Of the 103 family members for 88 patients, most were young (median age: 41 years) and female (75%). Language fluency was 44.6% English-only, 31.7% Spanish-only, and 23.8% bilingual. Mean summary family satisfaction scores (±SD) were 80.6±26.4 for satisfaction with care, 79.3±27.1 for satisfaction with decision-making, and 80.1±26.7 for total satisfaction. Respondents were less satisfied with the frequency of communication with physicians (70.7±27.4) and language translation (73.2±31.2). DISCUSSION: Overall family satisfaction with the care provided to patients in the TSICU is high, although opportunities for improvement were noted in the frequency of communication between physicians and family and language translation services. Further quality improvement projects are warranted. LEVEL OF EVIDENCE: Care management study: level V.
