Updates: This is the fourteenth version (thirteenth update) of the living guideline, replacing earlier versions (available as data supplements). New recommendations will be published as updates to this guideline.

Clinical Question: What is the role of drugs in the treatment of patients with covid-19?

Context: The evidence base for therapeutics for covid-19 is evolving with numerous randomised controlled trials (RCTs) recently completed and underway.

Auto-Processed Retinal Vessel Shadow View Images From Bedside Optical Coherence Tomography to Evaluate Plus Disease in Retinopathy of Prematurity.

Purpose: To describe the creation of en face retinal vessel shadow view (RVSV) optical coherence tomography (OCT) images and assess the feasibility of using these for evaluating vascular disease in preterm infants at risk for retinopathy of prematurity (ROP).

Methods: In this exploratory study, we selected images from eyes with a range of ROP vascular disease, prospectively acquired from preterm infants using an investigational, noncontact, handheld, bedside swept-source OCT. We autosegmented OCT volumes using custom infant-specific software, extracted RVSV-OCT images from volumetric data bracketed around the retinal pigment epithelium, and automontaged the resulting RVSV-OCT images.

Symptom Burden, School Function, and Physical Activity One Year Following Pediatric Concussion.

Objectives: To characterize symptom burden, school function, and physical activity in youth 1 year following acute concussion and those with subsequent repeat concussion.

Study Design: Secondary analysis of Predicting Persistent Postconcussive Problems in Pediatrics prospective, multicenter cohort study conducted in 9 Canadian emergency departments. Participants were children between ages 5 and 18 years who presented consecutively ≤48 hours of concussion and agreed to participate in a post hoc electronic survey 1 year after injury.

A pragmatic randomized controlled trial of multi-dose oral ondansetron for pediatric gastroenteritis (the DOSE-AGE study): statistical analysis plan.

Background: Acute gastroenteritis is a leading cause of emergency department visits and hospitalizations among children in North America. Oral-rehydration therapy is recommended for children with mild-to-moderate dehydration, but children who present with vomiting are frequently offered intravenous rehydration in the emergency department (ED). Recent studies have demonstrated that the anti-emetic ondansetron can reduce vomiting, intravenous rehydration, and hospitalization when administered in the ED to children with dehydration.

Update on nonantibiotic therapies for acute gastroenteritis.

Purpose Of Review: The aim of this review is to provide an update of nonantibiotic therapies for acute gastroenteritis (AGE), focusing on antiemetics and probiotics.

Recent Findings: The mainstay of therapy for nonsevere AGE remains oral rehydration therapy (ORT). Recent randomized controlled trials and metaanalyses have further strengthened the evidence-base supporting single-dose ondansetron administration in emergency departments to facilitate ORT based on evidence that it safely reduces intravenous fluid administration and hospitalization rates.

Influenza virus detection in the stool of children with acute gastroenteritis.

Objectives: To determine if the clinical characteristics of children with gastroenteritis and influenza identified in their stool differ from those whose stool was influenza-negative.

Methods: Children <18-years with gastroenteritis whose stool tested negative for enteropathogen were tested for influenza in stool. The clinical features between influenza-positive and influenza-negative gastroenteritis cases were compared.

Factors Associated With Nonadherence in an Emergency Department-based Multicenter Randomized Clinical Trial of a Probiotic in Children With Acute Gastroenteritis.

Nonadherence in clinical trials affects safety and efficacy determinations. Predictors of nonadherence in pediatric acute illness trials are unknown. We sought to examine predictors of nonadherence in a multicenter randomized trial of 971 children with acute gastroenteritis receiving a 5-day oral course of Lactobacillus rhamnosus GG or placebo.

Trends in Use of Advanced Imaging in Pediatric Emergency Departments, 2009-2018.

Importance: There is increased awareness of radiation risks from computed tomography (CT) in pediatric patients. In emergency departments (EDs), evidence-based guidelines, improvements in imaging technology, and availability of nonradiating modalities have potentially reduced CT use.

Objective: To evaluate changes over time and hospital variation in advanced imaging use.

Maltodextrin-induced intestinal injury in a neonatal mouse model.

Prematurity and enteral feedings are major risk factors for intestinal injury leading to necrotizing enterocolitis (NEC). An immature digestive system can lead to maldigestion of macronutrients and increased vulnerability to intestinal injury. The aim of this study was to test in neonatal mice the effect of maltodextrin, a complex carbohydrate, on the risk of intestinal injury.

DIGEST: Developing innovative gastroenterology specialty training.

Individuals with cystic fibrosis (CF) now have an increased life expectancy, due to advances in care provided by a multidisciplinary team. The care model has expanded over time to include multiple subspecialties. The Cystic Fibrosis Foundation conducted a survey of Care Center Directors and identified a need for pediatric and adult gastroenterologists with expertise in the diagnosis and treatment of intestinal, pancreatic and hepatic complications of CF.

Periocular infantile hemangioma masquerading as dacryocele.

A 2-month-old boy developed a protuberant, blue nodule inferomedial to the left medial canthus. It was unresponsive to oral and intramuscular antibiotics. After developing difficulty breathing, he was admitted, with the diagnosis of a dacryocele, and, after an inconclusive ultrasound, underwent probing and irrigation with nasal endoscopy.

Outcomes of Bilateral Cataract Surgery in Infants 7 to 24 Months of Age Using the Toddler Aphakia and Pseudophakia Treatment Study Registry.

Purpose: To evaluate outcomes of bilateral cataract surgery in children aged 7 to 24 months and compare rates of adverse events (AEs) with other Toddler Aphakia and Pseudophakia Study (TAPS) registry outcomes.

Design: Retrospective clinical study at 10 Infant Aphakia Treatment Study (IATS) sites. Statistical analyses comparing this cohort with previously reported TAPS registry cohorts.

International Practice Patterns of Antibiotic Therapy and Laboratory Testing in Bronchiolitis.

Background And Objectives: International patterns of antibiotic use and laboratory testing in bronchiolitis in emergency departments are unknown. Our objective is to evaluate variation in the use of antibiotics and nonindicated tests in infants with bronchiolitis in 38 emergency departments in Pediatric Emergency Research Networks in Canada, the United States, Australia and New Zealand, the United Kingdom and Ireland, and Spain and Portugal. We hypothesized there would be significant variation, adjusted for patient characteristics.

Disrupted inhibitory plasticity and homeostasis in Fragile X syndrome.

Fragile X Syndrome (FXS) is a neurodevelopmental disorder instigated by the absence of a key translation regulating protein, Fragile X Mental Retardation Protein (FMRP). The loss of FMRP in the CNS leads to abnormal synaptic development, disruption of critical periods of plasticity, and an overall deficiency in proper sensory circuit coding leading to hyperexcitable sensory networks. However, little is known about how this hyperexcitable environment affects inhibitory synaptic plasticity.

Post-traumatic stress disorder and postpartum depression and their reported association with recent labor and delivery: a questionnaire survey cohort.

Background: We aimed to investigate the index traumatic event associated with post-traumatic stress disorder (PTSD) and evaluate the timing of the onset of symptoms in relation to the recent delivery.

Methods: Questionnaire study regarding prior exposure to traumatic events, PTSD, postpartum depression (PPD) and fear of childbirth among women two to 12 months postpartum, recruited via targeted internet sites.

Results: Questionnaires were completed by 143 women, with PPD reported by 22 (15.

Overhead Mounted Optical Coherence Tomography in Childhood Glaucoma Evaluation.

Unlabelled: PRéCIS:: Overhead mounted spectral-domain optical coherence tomography (OCT) enables high-quality imaging of the optic nerve and macula in childhood glaucoma, and is particularly useful when standard tabletop OCT has failed or is not possible.

Purpose: Tabletop OCT, integral to adult glaucoma management, can be limited in childhood glaucoma patients because of young age, poor cooperation, and/or technical challenges. To address these imaging difficulties, we determined the feasibility and quality of an overhead mounted unit in childhood glaucoma.

Subclinical Retinal versus Brain Findings in Infants with Hypoxic Ischemic Encephalopathy.

Purpose: To detect retinal features and abnormalities on optical coherence tomography (OCT) without pupil dilation and relate these to brain injury in infants with a clinical diagnosis of hypoxic ischemic encephalopathy (HIE).

Methods: Under an institutional review board-approved protocol, we imaged eight infants without pharmacologic mydriasis, using handheld, non-contact spectral-domain (Leica Microsystems, IL) or investigational swept-source OCT at the bedside in an intensive care nursery, after birth (depending on primary clinical care team permission based on health status) and weekly until discharge. The newborn infant with HIE is neurologically unstable; therefore, pharmacologic mydriasis and stimulation with visible light for retinal examination are usually avoided.

Multi-dose Oral Ondansetron for Pediatric Gastroenteritis: study Protocol for the multi-DOSE oral ondansetron for pediatric Acute GastroEnteritis (DOSE-AGE) pragmatic randomized controlled trial.

Background: There are limited treatment options that clinicians can provide to children presenting to emergency departments with vomiting secondary to acute gastroenteritis. Based on evidence of effectiveness and safety, clinicians now routinely administer ondansetron in the emergency department to promote oral rehydration therapy success. However, clinicians are also increasingly providing multiple doses of ondansetron for home use, creating unquantified cost and health system resource use implications without any evidence to support this expanding practice.

A randomized trial evaluating virus-specific effects of a combination probiotic in children with acute gastroenteritis.

Gastroenteritis accounts for nearly 500,000 deaths in children younger than 5 years annually. Although probiotics have been touted as having the potential to expedite diarrhea resolution, recent clinical trials question their effectiveness. A potential explanation is a shift in pathogens following the introduction of a rotavirus vaccine.
