Short-term Postoperative Complications of Lymphatic Malformation Surgical Excision: A 20-Year Institutional Review.

Objective: To evaluate outcomes and postoperative complications following surgical resection of lymphatic malformations (LMs) at a single multidisciplinary vascular anomalies center.

Methods: A single-center retrospective review of all patients ≤21 years old who underwent surgical resection of a lymphatic malformation at a quaternary referral center with a multidisciplinary vascular anomalies team from 2004 to 2024. Data pertaining to postoperative outcomes and treatments was abstracted.

Pediatric Trauma Mortality Differs by Neighborhood Opportunity Level.

Objective: Traumatic injuries are a leading cause of death in children and a child's neighborhood characteristics can be a risk factor. Our objective was to describe the association between pediatric trauma mortality and Child Opportunity Index (COI).

Methods: A multicenter, retrospective cross-sectional study was conducted across 15 trauma centers from 2010 to 2021 within a large metropolitan county to evaluate trauma activation mortalities involving children <18 years-old.

Primary caregiver employment status is associated with traumatic brain injury in children in the USA.

Background: Traumatic brain injury (TBI) is a common injury in children. Previous literature has demonstrated that TBI may be associated with supervision level. We hypothesised that primary caregiver employment would be associated with child TBI.

FXR deletion attenuates intestinal barrier dysfunction in murine acute intestinal inflammation.

Accumulating literature suggests that the farnesoid-X receptor (FXR), a nuclear bile acid receptor best known for its role in bile acid homeostasis, is also a potent context-dependent regulator of inflammation. FXR may thus be relevant to several intestinal disease states including inflammatory bowel disease, necrotizing enterocolitis, and sepsis. In this study, we tested the effects of FXR deletion on acute murine intestinal inflammation.

Clinical Characteristics of Avoidable Patient Transfers for Suspected Pediatric Appendicitis.

Introduction: Pediatric surgical care is becoming increasingly regionalized, often resulting in limited access. Interfacility transfers pose a significant financial and emotional burden to when they are potentially avoidable. Of transferred patients, we sought to identify clinical factors associated with avoidable transfers in pediatric patients with suspected appendicitis.

A Standardized Post-gastrostomy Feeding Protocol for Pediatric Patients Reduces Time to Postoperative Goal Feeding Volume.

Background: Gastrostomy creation is a common pediatric surgical procedure, but the time to initiation of feeds and to goal feeding volumes postoperatively varies greatly. Delays in reaching goal feeding volumes promote malnutrition and may prolong hospital length of stay. We hypothesized that implementing an accelerated, standardized post-gastrostomy feeding protocol would allow patients to reach goal feeding volumes sooner, without increasing postoperative complications.

Evaluation of Postoperative Outcomes After Enterostomy Closure in Low Body Weight Infants: A Multi-Center Retrospective Analysis.

Background: The minimum weight for enterostomy closure (EC) in infants remains debated with the current acceptable cut-off of >2 kg. As enterostomy-related complications or high enterostomy output (>30cc/kg/d) may prohibit a premature infant from reaching 2 kg, additional data is needed to evaluate the safety of EC in infants <2 kg. The objective of this study was to evaluate postoperative outcomes in low body weight (<2 kg) infants undergoing EC compared to larger infants.

Seasonality and temporal variation of pediatric trauma in Southern California.

Introduction: Seasonality of pediatric trauma has been previously described, although the association of season with hour of presentation is less understood. Both factors have potential implications for resource allocation and team preparedness.

Methods: A multicenter retrospective study was conducted to analyze the records of injured children <18 years-old who presented to one of the 15 trauma centers within Los Angeles County.

Association Between Hospital Arrival Time and Avoidable Transfer in Pediatric Trauma.

Background: Avoidable transfers (AT) in pediatric trauma can increase strain on healthcare resources and families. We sought to identify characteristics of patients and their injuries that are associated with AT.

Methods: A multicenter retrospective cross-sectional study of the regional Trauma Registry was conducted from 1/1/10-12/31/21 of children <18 years-old who experienced an interfacility transfer.

Firearm Injuries in Lower Opportunity Neighborhoods During the COVID Pandemic.

Objectives: We aimed to describe changes in pediatric firearm injury rates, severity, and outcomes after the coronavirus disease 2019 stay-at-home order in Los Angeles (LA) County.

Methods: A multicenter, retrospective, cross-sectional study was conducted on firearm injuries involving children aged <18-years in LA County before and after the pandemic. Trauma activation data of 15 trauma centers in LA County from the Trauma and Emergency Medicine Information System Registry were abstracted from January 1, 2018, to December 31, 2021.
