SIPA Poorly Predicts Outcomes in Young Pediatric Trauma Patients.

Introduction: The shock index pediatric adjusted score (SIPA) predicts the need for blood transfusion (BT), hemorrhage control interventions (HCI), morbidity/mortality among older pediatric trauma patients but is less predictive in younger patients. We hypothesize that SIPA will be predictive among older pediatric patients for BT, HCI, mortality, and need for trauma intervention (NFTI), however we aim to further delineate the gap in utilizing SIPA in younger patients.

Methods: Using the ACS NTDB for 2017-2021 we evaluated patients 1-14 years old who were transported by EMS from the scene for definitive care.

Ethics of Pediatric Surgical Innovation: Considerations, Controversies, and Pitfalls.

AbstractThe field of surgery has relied on innovation and creativity to improve patient care and propel the field forward. Historically, regulatory oversight of innovative approaches to surgery has been largely inconsistent, rendering surgeons relatively unrestricted creative latitude in the operating room; whether this has proven to be more beneficial or harmful is subject to debate. While innovation plays a crucial role in the advancement of surgical techniques, the potential drawbacks of unregulated innovation must be seriously considered, especially when treating vulnerable populations such as infants and children.

Redox Chemistry: Implications for Necrotizing Enterocolitis.

Reduction-oxidation (redox) chemistry plays a vital role in human homeostasis. These reactions play critical roles in energy generation, as part of innate immunity, and in the generation of secondary messengers with various functions such as cell cycle progression or the release of neurotransmitters. Despite this cornerstone role, if left unchecked, the body can overproduce reactive oxygen species (ROS) or reactive nitrogen species (RNS).

Perforated Appendicitis in Children: Management, Microbiology, and Antibiotic Stewardship.

Although appendicitis has been described for more than 300 years, its optimal management remains a topic of active investigation. Acute appendicitis is the most common cause of peritonitis in children, and rates of perforated appendicitis are much higher in children than in adults. Increased risk for perforated appendicitis in children is related to a delay in diagnosis due to age, size, access to care, and more.

Pediatric Traumatic Lumbar Hernias and Associated Injuries: A Case Series.

Objective: Traumatic lumbar hernias are a rare entity mostly seen with high-impact, blunt abdominal trauma. This injury occurs when there is disruption of the posterior musculature along with bony structures, allowing for herniation of abdominal contents. There are minimal cases of this entity reported in adults, but even fewer in the pediatric population.

Despite Recovery from Necrotizing Enterocolitis Infants Retain a Hyperinflammatory Response to Injury.

Background: Necrotizing enterocolitis (NEC) is the leading gastrointestinal cause of death of premature neonates. NEC is associated with prematurity, a hyperinflammatory response, and dysregulation of intestinal barrier function. We hypothesize that patients with NEC will have, and continue to have after recovery, an increased hyperinflammatory intestinal response compared to those patients without NEC.

Caveolin-1: A Review of Intracellular Functions, Tissue-Specific Roles, and Epithelial Tight Junction Regulation.

Caveolin-1 (Cav1) is a vital protein for many cellular processes and is involved in both the positive and negative regulation of these processes. Cav1 exists in multiple cellular compartments depending on its role. Of particular interest is its contribution to the formation of plasma membrane invaginations called caveolae and its involvement in cytoskeletal interactions, endocytosis, and cholesterol trafficking.

The unfunded grant, now what? Advice, approach, and strategy.

Background: Grant writing takes significant time and effort and often may be elusive, especially on a first attempt. After the rejection of a grant, many investigators face a dilemma regarding the best next steps. In this article, we discuss the options of revision versus resubmission and how to navigate these decisions.

Response of the Glutathione (GSH) Antioxidant Defense System to Oxidative Injury in Necrotizing Enterocolitis.

Necrotizing enterocolitis (NEC) is a neonatal intestinal disease associated with oxidative stress. The targets of peroxidation and the role of the innate intestinal epithelial antioxidant defense system are ill-defined. We hypothesized that oxidative stress in NEC correlates with oxidized GSH redox potentials, lipid peroxidation, and a dysfunctional antioxidant system.

Persistent Proclivity to a Proinflammatory State in a Human Enteroid Model of Necrotizing Enterocolitis.

Necrotizing enterocolitis (NEC) is a devastating disease of premature neonates with substantial morbidity and mortality. Necrotizing enterocolitis is associated with prematurity, a hyperinflammatory response, and dysregulation of intestinal barrier function. We hypothesize that patients with NEC will have an increased hyperinflammatory intestinal response compared with those without NEC.

Anecdotes Drive Attitudes, Data Drives Decisions: Optimizing the Emergency Department Workup Prior to Surgical Consultations.

Purpose: Emergency department (ED) wait times and ED length of stay (LOS) have a significant impact on patient morbidity and mortality and patient satisfaction. Consultation-to-decision time can contribute to increased wait times and LOS in the ED. Up to 40% of patients presenting to the ED require consultation from subspecialty services.

Innovation versus Experimentation: An Application of Ethical Frameworks to the Acceptance of Fluorescence-Guided Pediatric Surgery.

Innovation is essential to the advancement of the field of pediatric surgery. The natural skepticism toward new technologies in pediatrics leads to frequent confusion of surgical innovation and research. Using fluorescence-guided surgery as an archetype for this ethical discussion, we apply existing conceptual frameworks of surgical innovation to understand the distinction between innovation and experimentation, acknowledging the spectrum and "grey zone" in between.

Development of the Neonatal Intestinal Barrier, Microbiome, and Susceptibility to NEC.

The function of the intestinal barrier is partially dependent on host maturity and the colonization patterns of the microbiome to which it is exposed. Premature birth and stressors of neonatal intensive care unit (NICU)-related support (e.g.

Bugs and the barrier: A review of the gut microbiome and intestinal barrier in necrotizing enterocolitis.

Necrotizing enterocolitis (NEC) is a devastating gastrointestinal disease that affects premature neonates. It frequently results in significant morbidity and mortality for those affected. Years of research into the pathophysiology of NEC have revealed it to be a variable and multifactorial disease.

Blunt Cerebrovascular Injury in Pediatric Hanging Victims.

Introduction: Incidence of blunt cerebrovascular injury (BCVI) following hanging in the pediatric population is ill-defined. Current guidelines recommend screening imaging during the initial trauma evaluation. Necessity of screening is questioned given BCVI is considered rare after hanging, especially when asymptomatic.

Ethics of Resident Involvement in Surgical Training.

Unlabelled: AbstractBackground: Attending surgeons must maintain balance between promoting education and assuring safe, transparent patient care. This investigation aimed to define ethics that guide surgical training. We hypothesized that resident autonomy in the operating room is influenced by attending approach to patients, specifically patients considered to be vulnerable.

A Retrospective Case Control Study Examining Procalcitonin as a Biomarker for Necrotizing Enterocolitis.

Procalcitonin (PCT) is a biomarker for sepsis, but its utility has not been investigated in necrotizing enterocolitis (NEC). Necrotizing enterocolitis is a devastating multisystem disease of infants that in severe cases requires surgical intervention. We hypothesize that an elevated PCT will be associated with surgical NEC.

Apical-Out Enteroids as an Innovative Model for Necrotizing Enterocolitis.

Introduction: Necrotizing enterocolitis (NEC) is a gastrointestinal disease of premature neonates. We previously validated a NEC enteroid model derived from human infant intestinal tissue. Typical enteroid configuration is basolateral-out (BO) without direct access to the luminal (apical) surface.

Translating the Value of the Academic Surgeon Into Salary, Time, and Resources.

Academic surgeons provide tremendous value to institutions including notoriety, publicity, cutting-edge clinical advances, extramural funding, and academic growth and development. In turn, these attributes may result in improved reputation scores and hospital or medical center rankings. While many hospital systems, schools of medicine, and departments of surgery claim to have a major commitment to academic surgery and research, academic surgeons are often undercompensated compared to clinically focused counterparts.

Updates and recommendations on the surgical management of NEC.

Necrotizing enterocolitis is a severe gastrointestinal disease of the infant. It most commonly targets those that are born prematurely. NEC has been associated with initiation of feeds and in most cases, it can be managed with antibiotics and bowel rest.

COVID-19-Related Intussusception: A Case Series and Review of the Literature.

Ileocolic intussusception is a common gastrointestinal emergency that occurs in infancy. Many cases are caused by anatomic lead points, such as hypertrophied Peyer's patches. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, which causes coronavirus disease 2019 (COVID-19), commonly presents with respiratory symptoms, however, its relation to intussusception remains unknown.

Determining Intestinal Permeability using Lucifer Yellow in an Apical-Out Enteroid Model.

Enteroids are an emerging research tool in the study of inflammatory bowel diseases such as necrotizing enterocolitis (NEC). They are traditionally grown in the basolateral-out (BO) conformation, where the apical surface of the epithelial cell faces the inner lumen. In this model, access to the luminal surface of enteroids for treatment and experimentation is challenging, which limits the ability to study host-pathogen interactions.

A Review of the Diagnosis and Treatment of Necrotizing Enterocolitis.
