Accuracy of point-of-care SARS-CoV-2 detection using buccal swabs in pediatric emergency departments.

To optimize the identification of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected children, specimen collection and testing method are crucial considerations. Ideally, specimen collection is easy and causes minimal discomfort, and the laboratory approach is simple, accurate, and rapid. In this prospective cohort study we evaluated the accuracy of a point-of care nucleic acid device using caregiver/patient self-collected buccal swabs.

Weight-control compensatory behaviors patterns and correlates: a scoping review.

Objective: Weight-control compensatory behaviors appear to be a commonly utilized strategy for health management. Individuals engaging in such behaviors believe that the negative consequences from unhealthy behaviors will be neutralized by the positive consequences of healthy behaviors. Existing research has not reached a consensus on whether such behaviors are beneficial to health.

Caregiver and Youth Characteristics That Influence Trust in Digital Health Platforms in Pediatric Care: Mixed Methods Study.

Background: Combining patient-generated health data and digital health platforms may improve patient experience and population health, mitigate rising health care costs, reduce clinician burnout, and enable health equity. However, lack of trust may be a notable barrier to the data-sharing required by such platforms. Understanding sociodemographic, health, and personal characteristics will enable developers and implementers of such technologies to consider these in their technical design requirements.

Gestational organophosphate esters (OPEs) and executive function in adolescence: The HOME Study.

Background: Evidence from toxicological studies indicate organophosphate esters (OPEs) are neurotoxic, but few epidemiological studies investigated associations between gestational OPEs and executive function.

Objective: To examine the associations between gestational concentrations of OPE urinary metabolites and executive function at 12 years.

Methods: We used data from 223 mother-adolescent dyads from the Health Outcomes of Measures of the Environment (HOME) Study.

Conducting Patient-Oriented Research in Pediatric Populations: A Narrative Review.

It has become increasingly common for researchers to partner with patients as members of the research team and collaborate to use their lived experiences to shape research priorities, interventions, dissemination, and more. The patient-oriented research (POR) model has been adopted by both adult and pediatric health researchers. This cultural change to conducting pediatric health research brings with it new methodologies, tools, challenges, and benefits.

Purpose: To identify which features of Sturge-Weber syndrome (SWS) were most associated with glaucoma onset, severity, and treatment failure at a tertiary care center.

Design: Retrospective cross-sectional study.

Subjects: Children who had SWS with and without glaucoma.

Review of clinical trials and guidelines for children and youth with mucopolysaccharidosis: outcome selection and measurement.

Background: To inform the development of a core outcome set (COS) for children and youth with mucopolysaccharidoses (MPS), we aimed to identify all outcomes and associated outcome measurement instruments that are reported in recent clinical trials and recommended as measurements in clinical management guidelines.

Methods: To identify English-language clinical trials and guidelines pertaining to MPS published between 2011 and mid-2021, we applied a comprehensive peer-reviewed search strategy to relevant databases and registers on May 16, 2021. Two reviewers independently screened retrieved citations and then full-text articles to determine eligibility for inclusion.

Butyrate Inhibits the HDAC8/NF-κB Pathway to Enhance Slc26a3 Expression and Improve the Intestinal Epithelial Barrier to Relieve Colitis.

Dietary fiber is known to promote the production of short-chain fatty acids (SCFAs) by gut bacteria, which can enhance intestinal epithelial barrier function and ameliorate intestinal inflammation in patients with inflammatory bowel disease (IBD). Interestingly, some IBD patients show reduced expression of solute carrier family member 3 (Slc26a3) in intestinal epithelial cells. The objective of this research was to investigate the interaction between SCFAs and Slc26a3 during colitis and assess how this interaction affects intestinal epithelial barrier function.

Transitioning to oral feeding: A retrospective cohort study of a family-centered, hunger-based tube weaning program.

Background: We investigated the effectiveness of a novel, hunger-based outpatient tube weaning program for children with feeding-tube dependency.

Methods: This interdisciplinary program induced hunger via rapid reduction in tube-fed calories, followed by 2 weeks of daily outpatient mealtime support and regular follow-up. Forty-one children (6.

Inflammasome activation links enteric Typhimurium infection to a rapid, cytokine-dependent increase in intestinal mucin release.

The host restricts serovar Typhimurium infection of the gut via inflammasome-dependent sloughing of infected epithelial cells. Here we determined that concurrent caspase 1/11-dependent release of the goblet cell-derived mucin, Muc2, into the intestinal lumen also controls burdens in infected mice. The increased release of mucins from goblet cells in the cecum and nearby proximal colon, and the subsequent thickening of the protective mucus barrier layer in the distal colon, were all dependent on the cytokines interleukin (IL)-18 and IL-22, as deficiencies in either cytokine resulted in reduced mucin secretion.

Adolescents' mental health is associated with food parenting practices among British Columbian families.

Background: Adolescence is a developmental period marked by significant changes related to the body and food parenting practices. However, few studies have explored child-level psychological correlates of these practices during adolescence. Our study examined whether adolescents' weight status, weight concerns, self-esteem, and anxiety were associated with food parenting practices, and whether these associations significantly differed by adolescents' gender among 297 families in British Columbia, Canada.

Enhancing HPV vaccine uptake in girls and boys - A qualitative analysis of Canadian school-based vaccination programs.

The purpose of this study was to better understand barriers and enabling conditions for HPV vaccination in school-based vaccination programs in Canada. Semi-structured interviews were conducted by telephone or in person with parents, nurses, and school staff (n = 50) in three Canadian provinces. Interviews explored views on HPV and HPV vaccination, strengths and weaknesses of the school-based HPV vaccination programs and proposed interventions to increase uptake.

Rhythmic high-amplitude delta with superimposed spikes (RHADS): a treatment dilemma.

Pathognomonic EEG patterns have been described in genetic conditions such as Angelman and Rett syndromes. EEG patterns along the ictal-interictal continuum have been increasingly recognized with the greater availability of continuous EEG monitoring; however, treatment decisions may be difficult with unpredictable clinical implications. Rhythmic High-Amplitude Delta Activity with Superimposed (Poly) Spikes (RHADS) has been described as a particular EEG pattern in POLG1 Alpers Syndrome.

Clear lens extraction and intraocular lens implantation to correct extreme myopia after retinopathy of prematurity.

We report 3 patients who developed extreme myopia after ROP laser treatment. Their subsequent optical correction was problematic, prompting bilateral clear lens extractions with intraocular lens implantation.

Participant-reported neurological events following immunization in the Canadian National Vaccine Safety Network-COVID-19 vaccine (CANVAS-COVID) study.

Introduction: The Canadian National Vaccine Safety Network (CANVAS) conducted active participant-based surveillance for adverse events following immunization during the COVID-19 vaccine campaign. This study evaluated the association between COVID-19 vaccination and neurological adverse events.

Methods: Participants were invited to complete online surveys to report health events that prevented daily activities and/or required medical attention within 7 days after COVID-19 vaccination or 7 days prior to the survey (unvaccinated controls); follow-up surveys were sent 7 months later.

Protein requirements in adults with phenylketonuria and bioavailability of glycomacropeptide compared to an l-amino acid-based product.

Background: Phenylketonuria (PKU) is caused by phenylalanine hydroxylase deficiency. Treatment is primarily a low-Phe diet combined with l-amino acid-based products (l-AA). Protein requirements in adults with PKU have not been directly determined.

Exome variant prioritization in a large cohort of hearing-impaired individuals indicates IKZF2 to be associated with non-syndromic hearing loss and guides future research of unsolved cases.

Although more than 140 genes have been associated with non-syndromic hereditary hearing loss (HL), at least half of the cases remain unexplained in medical genetic testing. One reason is that pathogenic variants are located in 'novel' deafness genes. A variant prioritization approach was used to identify novel (candidate) genes for HL.
