RESUMO
BACKGROUND: Access to and engagement with greenspace is related to improved health benefits. We sought to collaborate with community members as partners in research and co-creators in knowledge to better understand which components within a newcomer-dense community help or hinder individual and community efforts to access greenspace and nature-based activities. METHODS: We used photovoice methodology to engage with local residents in focus groups, photowalks, and photo-elicitation interviews. Themes were developed using direct content analysis. RESULTS: A total of 39 participants (ages 11-70 years; median years in Canada of 3.25 years) were engaged in this program of research. From the analysis, we developed four themes: (a) peace and beauty; (b) memories of home; (c) safety and cleanliness; and (d) welcoming strengthened and new opportunities. Participants associated nature with peace, citing it as "under-rated" but "vital" to the neighborhood. Via photographs and stories, participants also shared a multitude of safety concerns that prevent their access to green/outdoor spaces for healthy active living programs or activities (e.g., woodchip-covered playgrounds, ample amounts of garbage littering the park and school grounds, lack of timely ice removal on sidewalks, limited safe biking paths, and unsafe motor vehicle practices at the crosswalks surrounding local parks). CONCLUSION: To translate the key ideas and themes into an informed discussion with policy and decision-makers, we held an in-person exhibition and guided tour where community members, the lead photovoice researcher, and SCORE! principal investigator shared information about each theme in the form of a pseudo-narrative peppered with prepared discussion questions.
RESUMO
Objectives: Food insecurity (FI) is associated with a number of adverse child health outcomes and increased emergency department (ED) use. The COVID-19 pandemic exacerbated the financial hardship faced by many families. We sought to determine the prevalence of FI among children with ED visits, compare this to pre-pandemic rates, and describe associated risk factors. Methods: From September to December 2021, families presenting to a Canadian paediatric ED were asked to complete a survey screening for FI along with health and demographic information. Results were compared to data collected in 2012. Multivariable logistic regression was used to measure associations with FI. Results: In 2021, 26% (n = 173/665) of families identified as food insecure compared to 22.7% in 2012 (n = 146/644) a difference of 3.3% (95% CI [-1.4%, 8.1%]). In multivariable analysis, greater number of children in the home (OR 1.19, 95% CI [1.01, 1.41]), financial strain from medical expenses (OR 5.31, 95% CI [3.45, 8.18]), and a lack of primary care access (OR 1.27, 95% CI [1.08, 1.51]) were independent predictors of FI. Less than half of families with FI reported use of food charity, most commonly food banks, while one-quarter received help from family or friends. Families experiencing FI expressed a preference for support through free or low-cost meals and financial assistance with medical expenses. Conclusion: More than one in four families attending a paediatric ED screened positive for FI. Future research is needed to examine the effect of support interventions for families assessed in medical care facilities including financial support for those with chronic medical conditions.
RESUMO
Background: The co-presentation of severe obesity (SO) and global developmental delay (GDD) in Canadian preschool children has not been examined. However, SO and GDD may require syndromic diagnoses and unique management considerations. Objectives: To determine (1) minimum incidence; (2) age of onset and risk factors; and (3) health care utilization for co-presenting SO and GDD. Methods: Through the Canadian Paediatric Surveillance Program (CPSP), a monthly form was distributed to participants from February 2018 to January 2020 asking for reports of new cases of SO and GDD among children ≤5 years of age. We performed descriptive statistics for quantitative questions and qualitative content analysis for open-ended questions. Results: Forty-seven cases (64% male; 51% white; mean age: 3.5 ± 1.2 years) were included. Age of first weight concern was 2.5 ± 1.3 years and age of GDD diagnosis was 2.7 ± 1.4 years. Minimum incidence of SO and GDD was 3.3 cases per 100,000 for ≤5 years of age per year. Identified problems included school and/or behavioural problems (n = 17; 36%), snoring (n = 14; 30%), and asthma/recurrent wheeze (n = 10; 21%). Mothers of 32% of cases (n = 15) had obesity and 21% of cases (n = 10) received neonatal intensive care. Microarray was ordered for 57% (n = 27) of children. A variety of clinicians and services were accessed. As reported by CPSP participants, challenges faced by families and health service access were barriers to care. Conclusion: Children with SO and GDD have multiple comorbidities, and require early identification and referral to appropriate services. These cases may also benefit from additional testing to rule out known genetic obesity syndromes.
RESUMO
OBJECTIVES: To evaluate risk factors associated with surgical intervention and subperiosteal/orbital abscess in hospitalized children with severe orbital infections. STUDY DESIGN: We conducted a multicenter cohort study of children 2 months to 18 years hospitalized with periorbital or orbital cellulitis from 2009 to 2018 at 10 hospitals in Canada. Clinical details were extracted, and patients were categorized as undergoing surgical or medical-only management. Primary outcome was surgical intervention and the main secondary outcome was clinically important imaging. Logistic regression was used to identify predictors. RESULTS: Of 1579 patients entered, median age was 5.4 years, 409 (25.9%) had an orbital/subperiosteal abscess, and 189 (12.0%) underwent surgery. In the adjusted analysis, the risk of surgical intervention was associated with older age (age 9 to <14: aOR 3.9, 95% CI 2.3-6.6; and age 14 to ≤18 years: aOR 7.0, 95% CI 3.4-14.1), elevated C-reactive protein >120 mg/L (aOR 2.8, 95% CI 1.3-5.9), elevated white blood cell count of 12-20 000/µL (aOR 1.7, 95% CI 1.1-2.6), proptosis (aOR 2.6, 95% CI 1.7-4.0), and subperiosteal/orbital abscess (aOR 5.3, 95% CI 3.6-7.9). There was no association with antibiotic use before hospital admission, sex, presence of a chronic disease, temperature greater than 38.0°C, and eye swollen shut. Complications were identified in 4.7% of patients, including vision loss (0.6%), intracranial extension (1.6%), and meningitis (0.8%). CONCLUSIONS: In children hospitalized with severe orbital infections, older age, elevated C-reactive protein, elevated white blood cell count, proptosis, and subperiosteal/orbital abscess were predictors of surgical intervention.

Background: Obesity is a global public health concern. Given the widespread disruption caused by the SARS-CoV-2 pandemic, it is important to evaluate its impact on children with chronic health conditions. This study examines the health of paediatric patients with obesity enrolled in a tertiary hospital weight management program, before and 1 year into the COVID-19 pandemic. Methods: This is a retrospective chart review of patients aged 2 to 17 years enrolled in a paediatric weight management clinic. Mental health outcomes (i.e., new referrals to psychologist, social work, eating disorder program, incidence of dysregulated eating, suicidal ideation, and/or self-harm) and physical health (anthropometric measures) were compared before and 1 year into the pandemic. Results: Among the 334 children seen in either period, there was an increase in referrals to psychologist (12.4% versus 26.5%; P=0.002) and the composite mental health outcome (17.2% versus 30.2%; P=0.005) during the pandemic compared with pre-pandemic. In a subset of children (n=30) with anthropometric measures in both periods, there was a lower rate of decline in BMIz score (-1.5 [2.00] versus -0.3 [0.73]/year; P=0.002) and an increase in adiposity (-0.8 [4.64] versus 2.7 [5.54]%/year; P=0.043) during the pandemic. Discussion: The pandemic has impacted the mental and physical health of children with obesity engaged in a weight management clinic. While our study provides evidence of a negative impact on mental health outcomes and less improvement in anthropometric measures, future research when patients return to in-person care will enable further examination of our findings with additional objective measures.
RESUMO
OBJECTIVES: Bronchiolitis is the most common viral lower respiratory tract infection in children under age 2 for which high-flow nasal cannula (HFNC) is increasingly used. Understanding factors associated with HFNC failure is important to identify patients at risk for respiratory deterioration. The objective of this study was to evaluate patient characteristics associated with HFNC failure in bronchiolitis. METHODS: A retrospective review of patients aged 0 to 24 months, with bronchiolitis who received HFNC within a single tertiary paediatric intensive care unit, between January 2014 and December 2018 was conducted. HFNC treatment failure was defined as escalation to non-invasive positive pressure or invasive mechanical ventilation. Multivariable regression analysis was used to identify demographic, clinical, and biochemical parameters associated with HFNC failure. RESULTS: Two hundred eight patients met inclusion criteria, of which 61 (29.33%) failed HFNC. Risk factors for HFNC failure included younger age (odds ratio [OR] 1.12; 95% confidence interval [CI] 1.03, 1.23; P=0.011) and a Modified Tal score greater than 5 at 4 hours of HFNC therapy (OR 2.81; 95% CI 1.04, 7.64; P=0.042). Duration of HFNC in hours was protective (OR 0.94; 95% CI 0.92, 0.96; P<0.001), such that deterioration is less likely once patients have remained stable on HFNC for a prolonged time. CONCLUSION: This is the first study exploring predictors of HFNC failure among Canadian children with bronchiolitis. Patient age, HFNC duration, and Modified Tal score were associated with HFNC failure. These factors should be considered when initiating HFNC for bronchiolitis to identify patients at risk for deterioration.
RESUMO
BACKGROUND: Perinatal health-seeking behaviours are influenced by various factors, including personal beliefs. South Asian women, who often live within a wide kinship system, can be influenced by the advice and guidance of their mothers and/or mothers-in-law. METHODS: To explore the cultural health perceptions of South Asian grandmothers within this context, we used constructivist grounded theory to sample and interview 17 South Asian grandmothers who reside in Southern Ontario, Canada. Interviews were audio-recorded, transcribed verbatim, and coded/analyzed by three independent coders. RESULTS: Many grandmothers emphasized that the preconception phase should focus on building healthy habits around nutrition, physical activity, and mental wellness; the pregnancy period should encompass an enriched environment (positive relationships, healthy routines, nutritional enhancement); and the postpartum phase should emphasize healing and restoration for both the mother and newborn (self-care, bonding, rebuilding healthy habits). Many of the grandmothers conceptualized these stages as a cyclical relationship where healing and restoration transitions gradually to re-establishing healthy habits before having a subsequent child. They also expressed responsibility in supporting their daughters and/or daughters-in-law with their family units and encouraging the transfer of perinatal health information. CONCLUSIONS: South Asian grandmothers are involved in supporting the family units of their children and involving them in perinatal health programming can be an effective way to translate health knowledge to South Asian women. Video abstract. In order to impact a broad, diverse audience of community members, we collaborated with a South Asian film-maker to distil the research findings, write an impactful script, and produce a short digital story based on the research findings. Currently available on social media (https://www.youtube.com/watch?v=tjcNUVOwatU), the film was celebrated with a CIHR Institute for Human Development, Child and Youth Health Video Talks Prize in 2016.

Purpose: Validated methods to assess diet of non-European infants are sparse. We assessed the validity and reliability of a semi-quantitative food-frequency questionnaire (FFQ) for South Asian infants in Canada.Methods: We developed an 80-item FFQ to assess infant nutrient intake in the South Asian Birth Cohort study (START). Caregivers completed the FFQ twice along with two 24-hour diet recalls. We measured infant plasma ferritin to cross-validate reported iron intake. We evaluated validity using Spearman's rho (ρ), and reliability using the intraclass correlation coefficient.Results: Seventy-six caregivers provided 2 FFQs and 2 24-hour diet recalls. Energy-adjusted, de-attenuated correlations between the FFQs and 24-hour diet recalls ranged from -0.29 (monounsaturated fat) through 1.00 (cholesterol). The FFQ overestimated energy intake by 128%. Iron intake by 24-hour diet recalls correlated with plasma ferritin (r = 0.41; P = 0.01; n = 37), but iron intake by FFQ did not. The average reproducibility coefficient of the FFQ ranged from 0.24 (macronutrients) to 0.65 (minerals).Conclusions: Among South Asian infants living in Canada, at least 2 days of diet recall completed with the primary caregiver yields more valid and reproducible estimates of nutrient intakes than a semi-quantitative FFQ, and it highlights that careful selection of FFQ portion sizes is important for assessing dietary intake with an FFQ.

BACKGROUND: Canada is an ethnically diverse nation, which introduces challenges for health care providers tasked with providing evidence-based dietary advice. OBJECTIVES: We aimed to harmonize food-frequency questionnaires (FFQs) across 4 birth cohorts of ethnically diverse pregnant women to derive robust dietary patterns to investigate maternal and newborn outcomes. METHODS: The NutriGen Alliance comprises 4 prospective birth cohorts and includes 4880 Canadian mother-infant pairs of predominantly white European [CHILD (Canadian Healthy Infant Longitudinal Development) and FAMILY (Family Atherosclerosis Monitoring In earLY life)], South Asian [START (SouTh Asian birth cohoRT)-Canada], or Aboriginal [ABC (Aboriginal Birth Cohort)] origins. CHILD used a multiethnic FFQ based on a previously validated instrument designed by the Fred Hutchinson Cancer Research Center, whereas FAMILY, START, and ABC used questionnaires specifically designed for use in white European, South Asian, and Aboriginal people, respectively. The serving sizes and consumption frequencies of individual food items within the 4 FFQs were harmonized and aggregated into 36 common food groups. Principal components analysis was used to identify dietary patterns that were internally validated against self-reported vegetarian status and externally validated against a modified Alternative Healthy Eating Index (mAHEI). RESULTS: Three maternal dietary patterns were identified-"plant-based," "Western," and "health-conscious"-which collectively explained 29% of the total variability in eating habits observed in the NutriGen Alliance. These patterns were strongly associated with self-reported vegetarian status (OR: 3.85; 95% CI: 3.47, 4.29; r2 = 0.30, P < 0.001; for a plant-based diet), and average adherence to the plant-based diet was higher in participants in the fourth quartile of the mAHEI than in the first quartile (mean difference: 46.1%; r2 = 0.81, P < 0.001). CONCLUSION: Dietary data collected by using FFQs from ethnically diverse pregnant women can be harmonized to identify common dietary patterns to investigate associations between maternal dietary intake and health outcomes.

OBJECTIVE: The objective is to describe the experiences and perceptions of caregivers who participated in a community systems navigator intervention that addressed unmet social needs. DESIGN, SETTING AND PATIENTS: A qualitative descriptive study with caregivers of children enrolled in a clinical trial addressing unmet social needs of families with children cared for in a tertiary pediatric weight management clinic, through community systems navigation. Participants were asked open-ended questions related to perceptions of social needs screening in clinical settings. Interviews were recorded and analysed using Braun and Clarke's six-phase approach to thematic analysis. RESULTS: Ten parent participants were interviewed. Social needs screening perception and acceptability varied between participants. Social needs screening was comfortable for most but stressful for others. Participants noted that trusting relationships promote comfort with sharing social needs information, and this data should be shared on the electronic health record if accurate and purposeful. They found the online screening tool convenient but thought it could also limit opportunities to elaborate. Some participants noted the intervention of community systems navigation helpful; however, others described the need for more tailored resources. CONCLUSIONS: Screening for unmet social needs in clinical settings is complex and should be family centred, including the consideration of the mode of screening, data sharing in the electronic health record and ensuing interventions. Perspectives of families should drive the design of future larger scale community navigation interventions to address unmet social needs in clinical settings.

OBJECTIVE: The objective of this study was to understand caregiver perspectives and experiences relating to the treatment of paediatric community-acquired pneumonia (CAP). DESIGN, SETTING AND PATIENTS: This was a phenomenological qualitative study involving interviews with caregivers of young children in Hamilton, Ontario. Caregivers were asked open-ended questions relating to germ theory, pneumonia and the role of antibiotic treatment. The principles of conventional content analysis guided the coding and synthesis of the transcribed interviews. RESULTS: Eleven caregivers were interviewed. Many knew that antibiotics were not effective against all types of infections and stated that there was an increased risk of developing resistance with frequent use. However, there were misconceptions that probiotics effectively mitigated antibiotic side effects, and few were familiar with the potential long-term consequences of antibiotic use in children.There was variability in the perceived severity of paediatric CAP. Some participants thought that antibiotic treatment would accelerate recovery and prevent caregivers from feeling helpless. However, others also thought it was inappropriate for physicians to prescribe antibiotics solely to make the caregiver feel better. Many caregivers also felt strongly that clinical follow-up and discussions on treatment risks/benefits would be desirable to counteract feelings of helplessness that result from being sent home without a prescription. CONCLUSION: Recognising that parents may have misperceptions about antibiotic use for CAP (and may seek antibiotics without strong rationale) can inform clinicians' efforts to better educate and support caregivers in the emergency department. Care strategies informed by caregiver experiences can improve parent-provider communication and reduce antibiotic misuse.

A mother's intrauterine environment influences her health and that of her offspring, at birth and in the future. Herein, we present an overview of our Canadian Institutes of Health Research (CIHR)-funded grant "Understanding the impact of maternal and infant nutrition on infant/child health"-set within The NutriGen Birth Cohort Alliance. NutriGen is a consortium of four Canadian prospective birth cohorts representing >5000 mother-child pairs of diverse ethnic groups including South Asians, White Europeans, and Indigenous peoples. We summarize our objectives and main findings on outcomes of maternal diet, gestational diabetes, birth weight, cardiometabolic health, the microbiome, and epigenetic modifications. We append this work with 10 key messages when conducting multiethnic research and review our knowledge translation products. We describe the clinical impact of our research on maternal and child health and conclude with future directions on biomarker discovery, expansion to other ethnic groups, and interventions for high-risk populations.
RESUMO
OBJECTIVE: South Asians represent the largest non-white ethnic group in Canada and were disproportionately impacted by the COVID-19 pandemic. We sought to determine the factors associated with vaccine hesitancy in South Asian Canadians. METHODS: We conducted a cross-sectional analysis of vaccine hesitancy using data collected at the baseline assessment of a prospective cohort study, COVID CommUNITY South Asian. Participants (18 + years) were recruited from the Greater Toronto and Hamilton Area in Ontario (ON) and the Greater Vancouver Area in British Columbia (BC) between April and November 2021. Demographic characteristics and vaccine attitudes measured by the Vaccine Attitudes Examination (VAX) scale were collected. Each item is scored on a 6-point Likert scale, and higher scores reflect greater hesitancy. A multivariable linear mixed effects model was used to identify sociodemographic factors associated with vaccine hesitancy, adjusting for multiple covariates. RESULTS: A total of 1496 self-identified South Asians (52% female) were analyzed (mean age = 38.5 years; standard deviation (SD): 15.3). The mean VAX score was 3.2, SD: 0.8 [range: 1.0â6.0]. Factors associated with vaccine hesitancy included: time since immigration (p = 0.04), previous COVID-19 infection (p < 0.001), marital status (p < 0.001), living in a multigenerational household (p = 0.03), age (p = 0.02), education (p < 0.001), and employment status (p = 0.001). CONCLUSION: Among South Asians living in ON and BC, time since immigration, prior COVID-19 infection, marital status, living in a multigenerational household, age, education, and employment status were associated with vaccine hesitancy. This information can be used to address vaccine hesitancy in the South Asian population in future COVID-19 waves or pandemics.
RéSUMé: OBJECTIF: Les Asiatiques du Sud, qui représentent le plus grand groupe ethnique non-blanc au Canada, ont été démesurément touchés par la pandémie de COVID-19. Nous avons cherché à déterminer les facteurs associés à l'hésitation vaccinale chez les Canadiennes et les Canadiens asiatiques du Sud. MéTHODE: Nous avons mené une analyse transversale de l'hésitation vaccinale à l'aide des données collectées durant l'évaluation préliminaire d'une étude de cohorte prospective du nom de COVID CommUNITY South Asian. Les personnes participantes (18 ans et plus) ont été recrutées dans la région du grand Toronto et de Hamilton, en Ontario, et dans la région du Grand Vancouver, en Colombie-Britannique, entre avril et novembre 2021. Le profil démographique et les attitudes face aux vaccins, mesurées selon l'échelle Vaccine Attitudes Examination (VAX), ont été obtenus. Chaque élément a été noté selon une échelle de Likert en 6 points (plus la note est élevée, plus l'hésitation vaccinale est importante). Un modèle linéaire multivarié à effets mixtes a servi à identifier les facteurs sociodémographiques associés à l'hésitation vaccinale, en rajustant les données pour tenir compte de plusieurs covariables. RéSULTATS: En tout, 1 496 personnes s'identifiant comme étant Asiatiques du Sud (dont 52 % de femmes) ont été analysées (âge moyen = 38,5 ans; écart-type [S] : 15,3). La note VAX moyenne était de 3,2, S : 0,8 [intervalle : 1,0â6,0]. Les facteurs associés à l'hésitation vaccinale étaient : le temps écoulé depuis l'immigration (p = 0,04), une infection antérieure par la COVID-19 (p < 0,001), l'état matrimonial (p < 0,001), le fait de vivre dans un ménage multigénérationnel (p = 0,03), l'âge (p = 0,02), l'instruction (p < 0,001) et la situation d'emploi (p = 0,001). CONCLUSION: Chez les Asiatiques du Sud vivant en Ontario et en Colombie-Britannique, le temps écoulé depuis l'immigration, une infection antérieure par la COVID-19, l'état matrimonial, le fait de vivre dans un ménage multigénérationnel, l'âge, l'instruction et la situation d'emploi étaient associés à l'hésitation vaccinale. Ces informations peuvent être utilisées pour aborder l'hésitation vaccinale dans la population asiatique du Sud lors de vagues de COVID-19 ou de pandémies futures.
RESUMO
We evaluated the effectiveness of COVID-19 vaccines among South Asians living in Ontario, Canada compared to non-South Asians and compared the odds of symptomatic COVID-19 infection and related hospitalizations and deaths among non-vaccinated South Asians and non-South Asians. This was a test negative design study conducted in Ontario, Canada between December 14, 2020 and November 15, 2021. All eligible individuals >18 years with symptoms of COVID-19 were subdivided by ethnicity (South Asian vs other) and vaccination status (vaccinated versus not). The primary outcome was vaccine effectiveness as defined by COVID-19 infections, hospitalizations, and deaths, and secondary outcome was the odds of COVID-19 infections, hospitalizations, and death comparing non-vaccinated South Asians to non-vaccinated non-South Asians. 883,155 individuals were included. Among South Asians, two doses of COVID-19 vaccine prevented 93.8% (95% CI 93.2, 94.4) of COVID-19 infections and 97.5% (95% CI 95.2, 98.6) of hospitalizations and deaths. Among non-South Asians, vaccines prevented 86.6% (CI 86.3, 86.9) of COVID-19 infections and 93.1% (CI 92.2, 93.8) of hospitalizations and deaths. Non-vaccinated South Asians had higher odds of symptomatic SARS-CoV-2 infection compared to non-vaccinated non-South Asians (OR 2.35, 95% CI 2.3, 2.4), regardless of their immigration status. COVID-19 vaccines are effective in preventing infections, hospitalizations and deaths among South Asians living in Canada. The observation that non-vaccinated South Asians have higher odds of symptomatic COVID-19 infection warrants further investigation.
RESUMO
Importance: Hypertension affects 6% of all children, and its prevalence is increasing. Childhood hypertension tracks into adulthood and is associated with subclinical cardiovascular disease; however, there is a lack of evidence linking childhood hypertension to cardiovascular outcomes, which may contribute to underdiagnosis and undertreatment. Objective: To determine the long-term associated risk of major adverse cardiac events (MACE) among children diagnosed with hypertension. Design, Setting, and Participants: This was a population-based, retrospective, matched cohort study conducted from 1996 to 2022. The study included all children (aged 3-18 years) alive in Ontario, Canada, from 1996 to 2021, who were identified using provincial administrative health databases. Children with prior kidney replacement therapy were excluded. Exposure: Incident hypertension diagnosis, identified by validated case definitions using diagnostic and physician billing claims. Each case was matched with 5 controls without hypertension by age, sex, birth weight, maternal gestational hypertension, prior comorbidities (chronic kidney disease, diabetes, cardiovascular surgery), and a propensity score for hypertension. Main Outcomes and Measures: The primary outcome was MACE (a composite of cardiovascular death, stroke, hospitalization for myocardial infarction or unstable angina, or coronary intervention). Time to MACE was evaluated using the Kaplan-Meier method and Cox proportional hazards regression. Results: A total of 25â¯605 children (median [IQR] age, 15 [11-17] years; 14â¯743 male [57.6%]) with hypertension were matched to 128â¯025 controls without hypertension. Baseline covariates were balanced after propensity score matching, and prior comorbidities were uncommon (hypertension vs control cohort: malignancy, 1451 [5.7%] vs 7908 [6.2%]; congenital heart disease, 1089 [4.3%] vs 5408 [4.2%]; diabetes, 482 [1.9%] vs 2410 [1.9%]). During a median (IQR) of 13.6 (7.8-19.5) years of follow-up, incidence of MACE was 4.6 per 1000 person-years in children with hypertension vs 2.2 per 1000 person-years in controls (hazard ratio, 2.1; 95% CI, 1.9-2.2). Children with hypertension were at higher associated risk of stroke, hospitalization for myocardial infarction or unstable angina, coronary intervention, and congestive heart failure, but not cardiovascular death, compared with nonhypertensive controls. Conclusions and Relevance: Children diagnosed with hypertension had a higher associated long-term risk of MACE compared with controls without hypertension. Improved detection, follow-up, and control of pediatric hypertension may reduce the risk of adult cardiovascular disease.

OBJECTIVES: To examine 2 hospital oxygen saturation target policies and clinical outcomes in infants hospitalized with bronchiolitis. METHODS: This multicenter cohort study used data collected from a randomized clinical trial of infants aged 4 weeks to 24 months, hospitalized with bronchiolitis at children's and community hospitals from 2016 to 2019. We modeled the association between hospital oxygen saturation target policy, either 90% while awake and 88% while asleep (90%/88%) or 90% while awake and asleep (90%/90%), and clinical outcomes. RESULTS: A total of 162 infants were enrolled at 4 hospitals using a 90%/88% oxygen saturation target and 67 infants at 2 hospitals using a 90%/90% target policy. No significant differences between the 90%/88% group and 90%/90% groups were observed for time to discharge (adjusted hazard ratio, 0.83; 95% confidence interval [CI], 0.61-1.14; P = .25), initiation of supplemental oxygen (adjusted odds ratio [aOR], 0.98; 95% CI, 0.47-2.02; P = .95), time to discontinuation of supplemental oxygen (adjusted hazard ratio, 0.75; 95% CI, 0.44-1.27; P = .28), revisits (aOR, 1.38; 95% CI, 0.52-3.71; P = .52), and parent days missed from work (aOR, 2.41; 95% CI, 0.90-6.41; P = .08). Three infants in the 90%/88% group and none in the 90%/90% group were transferred to the ICU. CONCLUSIONS: Among infants hospitalized with bronchiolitis, clinical outcomes were similar between a hospital oxygen saturation target policy of 90% while awake and 88% while asleep compared with 90% while awake and asleep. These findings may inform the design of future trials of oxygen saturation targets in bronchiolitis hospital care.

OBJECTIVE: To determine the association of initial empiric antibiotic regimens with clinical outcomes in hospitalised children with severe orbital infections. DESIGN: Multi-centre observational cohort study using data from 2009 to 2018 clinical records. SETTING: Canadian children's hospitals (7) and community hospitals (3). PATIENTS: Children between 2 months and 18 years hospitalised for >24 hours with severe orbital infections. INTERVENTIONS: Empiric intravenous antibiotic regimen in the first 24 hours of hospitalisation. MAIN OUTCOME MEASURES: Length of hospital stay and surgical intervention using multivariable median regression and multivariate logistic regression, with adjustment for covariates. RESULTS: Of 1421 patients, 60.0% were male and the median age was 5.5 years (IQR 2.4-9.9). Median length of stay was 86.4 hours (IQR 56.9-137.5) and 180 (12.7%) received surgical intervention. Patients receiving broad-spectrum empiric antibiotics had an increased median length of stay, ranging from an additional 13.8 hours (third generation cephalosporin and anaerobic coverage) to 19.5 hours (third generation cephalosporin, staphylococcal and anaerobic coverage). No antibiotic regimen was associated with a change in the odds of surgical intervention. These findings remained unchanged in sensitivity analyses restricted to more severely ill patients. There was a twofold increase in the percentage of patients receiving the broadest empiric antibiotic regimens containing both staphylococcal and anaerobic coverage from 17.8% in 2009 to 40.3% in 2018. CONCLUSIONS: Empiric use of broad-spectrum antibiotics with staphylococci and anaerobic coverage was associated with longer length of stay and similar rates of surgery in children with orbital infections. There is an urgent need for comparative effectiveness studies of various antibiotic regimes.
RESUMO
INTRODUCTION: Incorporating shared decision-making (SDM) with children and families in hospitals was a top priority identified by patients, caregivers, and clinicians. Bronchiolitis, a common and costly reason for hospitalization in children, is an exemplar condition to study SDM in hospitals. Internationally, clinical practice guidelines differ when recommending intravenous (IV or parenteral) or nasogastric (NG or enteral) fluids for hospitalized infants with bronchiolitis who are unsafe to be fed orally. While evidence indicates that either IV or NG fluids are safe and effective, parent involvement in SDM in selecting IV or NG fluids is unknown. Our aim is to generate knowledge of SDM with parents in choosing between IV or NG fluids and the benefits and harms of these two treatment options for hospitalized children with bronchiolitis. METHOD: This is a multicenter, prospective, observational study, including children aged <12 months admitted to hospital with bronchiolitis requiring supplemental IV or NG fluids. The primary outcome will evaluate the extent of SDM in choosing IV versus NG fluids using the validated CollaboRATE tool. Secondary outcomes include the proportion of parents provided a choice of IV versus NG fluids; parent knowledge of fluid therapy; rate of fluids; length of hospital stay; and complications. DISCUSSION: This study will evaluate the extent of SDM in hospitalized infants with bronchiolitis who require IV or NG fluids and will evaluate both patient-centered and clinical outcomes that are relevant to clinical practice.
RESUMO
Importance: The COVID-19 pandemic resulted in multiple socially restrictive public health measures and reported negative mental health impacts in youths. Few studies have evaluated incidence rates by sex, region, and social determinants across an entire population. Objective: To estimate the incidence of hospitalizations for mental health conditions, stratified by sex, region, and social determinants, in children and adolescents (hereinafter referred to as youths) and young adults comparing the prepandemic and pandemic-prevalent periods. Design, Setting, and Participants: This Canadian population-based repeated ecological cross-sectional study used health administrative data, extending from April 1, 2016, to March 31, 2023. All youths and young adults from 6 to 20 years of age in each of the Canadian provinces and territories were included. Data were provided by the Canadian Institute for Health Information for all provinces except Quebec; the Institut National d'Excellence en Santé et en Services Sociaux provided aggregate data for Quebec. Exposures: The COVID-19-prevalent period, defined as April 1, 2020, to March 31, 2023. Main Outcomes and Measures: The main outcome measures were the prepandemic and COVID-19-prevalent incidence rates of hospitalizations for anxiety, mood disorders, eating disorders, schizophrenia or psychosis, personality disorders, substance-related disorders, and self-harm. Secondary measures included hospitalization differences by sex, age group, and deprivation as well as emergency department visits for the same mental health conditions. Results: Among Canadian youths and young adults during the study period, there were 218 101 hospitalizations for mental health conditions (ages 6 to 11 years: 5.8%, 12 to 17 years: 66.9%, and 18 to 20 years: 27.3%; 66.0% female). The rate of mental health hospitalizations decreased from 51.6 to 47.9 per 10 000 person-years between the prepandemic and COVID-19-prevalent years. However, the pandemic was associated with a rise in hospitalizations for anxiety (incidence rate ratio [IRR], 1.11; 95% CI, 1.08-1.14), personality disorders (IRR, 1.21; 95% CI, 1.16-1.25), suicide and self-harm (IRR, 1.10; 95% CI, 1.07-1.13), and eating disorders (IRR, 1.66; 95% CI, 1.60-1.73) in females and for eating disorders (IRR, 1.47; 95% CI, 1.31-1.67) in males. In both sexes, there was a decrease in hospitalizations for mood disorders (IRR, 0.84; 95% CI, 0.83-0.86), substance-related disorders (IRR, 0.83; 95% CI, 0.81-0.86), and other mental health disorders (IRR, 0.78; 95% CI, 0.76-0.79). Conclusions and Relevance: This cross-sectional study of Canadian youths and young adults found a rise in anxiety, personality disorders, and suicidality in females and a rise in eating disorders in both sexes in the COVID-19-prevalent period. These results suggest that in future pandemics, policymakers should support youths and young adults who are particularly vulnerable to deterioration in mental health conditions during public health restrictions, including eating disorders, anxiety, and suicidality.
