Visits to Alberta Emergency Departments for Child Mental Health Concerns During the COVID-19 Pandemic: An Examination of Visit Trends in Relation to School Closures and Reopenings.

OBJECTIVE: We examined emergency department (ED) mental health visit trends by children in relation to periods of school closure and reopening during the COVID-19 pandemic in Alberta, Canada. METHODS: Mental health visits by school-aged children (5 to <18 years) were extracted from the Emergency Department Information System, a province-wide database, from March 11, 2020, to November 30, 2021 (pandemic period; n = 18,997) and March 1, 2019, to March 10, 2020 (1-year, prepandemic comparator period; n = 11,540). We calculated age-specific visit rates and compared rate differences between periods of school closure (March 15-June 30, 2020; November 30, 2020-January 10, 2021; April 22-June 30, 2021) and reopening (September 4-November 29, 2020; January 11-April 21, 2021; September 3-November 30, 2021) to matched prepandemic periods. We used a ratio of relative risk to examine the risk of a visit during closures versus reopenings. RESULTS: The cohort included 11,540 prepandemic visits and 18,997 pandemic visits. Compared with prepandemic periods, ED visit rates increased across all ages during the first (+85.53%; 95% confidence interval [CI], 73.68% to 100.41%) and third (+19.92%; 95% CI, 13.28% to 26.95%) school closures, and decreased during the second closure (-15.37%; 95% CI, -22.22% to -7.92%). During school reopenings, visit rates decreased across all ages during the first reopening (-9.30%; 95% CI, -13.94% to -4.41%) and increased during the third reopening (+13.59%; 95% CI, 8.13% to 19.34%); rates did not change significantly during the second reopening (2.54%; 95% CI, -3.45% to 8.90%). The risk of a visit during school closure versus reopening was only higher for the first closure with 2.06 times the risk (95% CI, 1.88 to 2.25). CONCLUSIONS: Emergency department mental health visit rates were highest during the first school closure of the COVID-19 pandemic, and the risk of a visit during this closure period was twice compared with when schools first reopened.

Liver transaminase concentrations in children with acute SARS-CoV-2 infection.

OBJECTIVE: To evaluate the relationship between SARS-CoV-2 infection and liver injury by comparing transaminase concentrations among children tested for SARS-CoV-2 and other respiratory viruses in pediatric emergency departments. DESIGN & METHODS: Eligible children were <18 years with suspected SARS-CoV-2, tested using molecular approaches in emergency departments between March 7, 2020, and June 15, 2021 (Pediatric Emergency Research Network), and between August 6, 2020, and February 22, 2022 (Pediatric Emergency Research Canada). We compared aspartate (AST) and alanine aminotransferase (ALT) concentrations at presentation for SARS-CoV-2 and other respiratory viruses through a multivariate linear regression model, with the natural log of serum transaminase concentrations as dependent variables. RESULTS: Of 16,892 enrolled children, 2,462 (14.6%) had transaminase concentrations measured; 4318 (25.6%) were SARS-CoV-2 positive, and 3932 (23.3%) were tested for additional respiratory viruses. Among study participants who had additional respiratory virus testing performed, the most frequently identified viruses were enterovirus/rhinovirus [8.7% (343/3,932)], respiratory syncytial virus [4.6% (181/3,932)], and adenovirus [2.6% (103/3,932)]. Transaminase concentrations were elevated in 25.6% (54/211) of children with isolated SARS-CoV-2 detection and 21.6% (117/541) of those with no virus isolated; P = 0.25. In the multivariable model, isolated SARS-CoV-2 detection was not associated with elevated ALT (adjusted geometric mean ratio (IU/L): 0.96; 95%Confidence Interval (CI): 0.84, 1.08) or AST (adjusted geometric mean ratio (IU/L): 1.03; 95%CI: 0.92, 1.16) concentrations, with negative respiratory panel as the referent group. Ninety-day follow-up was completed in 82.2% (3,550/4,318) of SARS-CoV-2 positive children; no cases of new-onset liver disease were reported. CONCLUSION: Among those tested, transaminase concentrations did not vary between SARS-CoV-2-positive children and those with a negative respiratory viral panel. In multivariate analysis, SARS-CoV-2 infection was not associated with increased initial transaminase concentrations compared to other respiratory viruses.

Comparison of Symptoms Associated With SARS-CoV-2 Variants Among Children in Canada.

Importance: Clinical manifestations of SARS-CoV-2 variants have not been systematically compared in children. Objective: To compare symptoms, emergency department (ED) chest radiography, treatments, and outcomes among children with different SARS-CoV-2 variants. Design, Setting, and Participants: This multicenter cohort study was performed at 14 Canadian pediatric EDs. Participants included children and adolescents younger than 18 years (hereinafter referred to as children) tested for SARS-CoV-2 infection in an ED between August 4, 2020, and February 22, 2022, with 14 days of follow-up. Exposure(s): SARS-CoV-2 variants detected on a specimen collected from the nasopharynx, nares, or throat. Main Outcomes and Measures: The primary outcome was presence and number of presenting symptoms. The secondary outcomes were presence of core COVID-19 symptoms, chest radiography findings, treatments, and 14-day outcomes. Results: Among 7272 participants presenting to an ED, 1440 (19.8%) had test results positive for SARS-CoV-2 infection. Of these, 801 (55.6%) were boys, with a median age of 2.0 (IQR, 0.6-7.0) years. Children with the Alpha variant reported the fewest core COVID-19 symptoms (195 of 237 [82.3%]), which were most often reported by participants with Omicron variant infection (434 of 468 [92.7%]; difference, 10.5% [95% CI, 5.1%-15.9%]). In a multivariable model with the original type as the referent, the Omicron and Delta variants were associated with fever (odds ratios [ORs], 2.00 [95% CI, 1.43-2.80] and 1.93 [95% CI, 1.33-2.78], respectively) and cough (ORs, 1.42 [95% CI, 1.06-1.91] and 1.57 [95% CI, 1.13-2.17], respectively). Upper respiratory tract symptoms were associated with Delta infection (OR, 1.96 [95% CI, 1.38-2.79]); lower respiratory tract and systemic symptoms were associated with Omicron variant infection (ORs, 1.42 [95% CI, 1.04-1.92] and 1.77 [95% CI, 1.24-2.52], respectively). Children with Omicron infection most often had chest radiography performed and received treatments; compared with those who had Delta infection, they were more likely to have chest radiography performed (difference, 9.7% [95% CI, 4.7%-14.8%]), to receive intravenous fluids (difference, 5.6% [95% CI, 1.0%-10.2%]) and corticosteroids (difference, 7.9% [95% CI, 3.2%-12.7%]), and to have an ED revisit (difference, 8.8% [95% CI, 3.5%-14.1%]). The proportions of children admitted to the hospital and intensive care unit did not differ between variants. Conclusions and Relevance: The findings of this cohort study of SARS-CoV-2 variants suggest that the Omicron and Delta variants were more strongly associated with fever and cough than the original-type virus and the Alpha variant. Children with Omicron variant infection were more likely to report lower respiratory tract symptoms and systemic manifestations, undergo chest radiography, and receive interventions. No differences were found in undesirable outcomes (ie, hospitalization, intensive care unit admission) across variants.

Protective Factors Contributing to Academic Resilience in College Students During COVID-19

We sought to examine the potential environmental protective factors contributing to academic resilience among college students during emergency distance education. Data were collected from a sample of undergraduate students (n = 195) representing various majors and academic classifications. Our study results revealed that students perceived their motivation and comprehension of course material during emergency distance education as significantly lower than those before emergency distance education. Moreover, over 26% of the participants reported a decreased GPA during this period. However, a positive physical learning environment and student-perceived teacher academic support benefited students' academic performance. Interestingly, the physical learning environment positively predicted teacher academic support, β=.31, t(193) = 4.32, p < .001. The physical learning environment also explained a significant proportion of variance in teacher academic support scores, R 2 = .08, F(1, 193) = 16.25, p < .001, suggesting student perceptions of teacher support partially depends on their physical learning environment. Finally, students that had a higher classification were more likely to report an increased GPA;seniors were better at coping with the negative effects of emergency distance education than juniors and sophomores.

Post-COVID-19 Conditions Among Children 90 Days After SARS-CoV-2 Infection.

Importance: Little is known about the risk factors for, and the risk of, developing post-COVID-19 conditions (PCCs) among children. Objectives: To estimate the proportion of SARS-CoV-2-positive children with PCCs 90 days after a positive test result, to compare this proportion with SARS-CoV-2-negative children, and to assess factors associated with PCCs. Design, Setting, and Participants: This prospective cohort study, conducted in 36 emergency departments (EDs) in 8 countries between March 7, 2020, and January 20, 2021, included 1884 SARS-CoV-2-positive children who completed 90-day follow-up; 1686 of these children were frequency matched by hospitalization status, country, and recruitment date with 1701 SARS-CoV-2-negative controls. Exposure: SARS-CoV-2 detected via nucleic acid testing. Main Outcomes and Measures: Post-COVID-19 conditions, defined as any persistent, new, or recurrent health problems reported in the 90-day follow-up survey. Results: Of 8642 enrolled children, 2368 (27.4%) were SARS-CoV-2 positive, among whom 2365 (99.9%) had index ED visit disposition data available; among the 1884 children (79.7%) who completed follow-up, the median age was 3 years (IQR, 0-10 years) and 994 (52.8%) were boys. A total of 110 SARS-CoV-2-positive children (5.8%; 95% CI, 4.8%-7.0%) reported PCCs, including 44 of 447 children (9.8%; 95% CI, 7.4%-13.0%) hospitalized during the acute illness and 66 of 1437 children (4.6%; 95% CI, 3.6%-5.8%) not hospitalized during the acute illness (difference, 5.3%; 95% CI, 2.5%-8.5%). Among SARS-CoV-2-positive children, the most common symptom was fatigue or weakness (21 [1.1%]). Characteristics associated with reporting at least 1 PCC at 90 days included being hospitalized 48 hours or more compared with no hospitalization (adjusted odds ratio [aOR], 2.67 [95% CI, 1.63-4.38]); having 4 or more symptoms reported at the index ED visit compared with 1 to 3 symptoms (4-6 symptoms: aOR, 2.35 [95% CI, 1.28-4.31]; ≥7 symptoms: aOR, 4.59 [95% CI, 2.50-8.44]); and being 14 years of age or older compared with younger than 1 year (aOR, 2.67 [95% CI, 1.43-4.99]). SARS-CoV-2-positive children were more likely to report PCCs at 90 days compared with those who tested negative, both among those who were not hospitalized (55 of 1295 [4.2%; 95% CI, 3.2%-5.5%] vs 35 of 1321 [2.7%; 95% CI, 1.9%-3.7%]; difference, 1.6% [95% CI, 0.2%-3.0%]) and those who were hospitalized (40 of 391 [10.2%; 95% CI, 7.4%-13.7%] vs 19 of 380 [5.0%; 95% CI, 3.0%-7.7%]; difference, 5.2% [95% CI, 1.5%-9.1%]). In addition, SARS-CoV-2 positivity was associated with reporting PCCs 90 days after the index ED visit (aOR, 1.63 [95% CI, 1.14-2.35]), specifically systemic health problems (eg, fatigue, weakness, fever; aOR, 2.44 [95% CI, 1.19-5.00]). Conclusions and Relevance: In this cohort study, SARS-CoV-2 infection was associated with reporting PCCs at 90 days in children. Guidance and follow-up are particularly necessary for hospitalized children who have numerous acute symptoms and are older.

Corticosteroids and Other Treatments Administered to Children Tested for SARS-CoV-2 Infection in Emergency Departments.

OBJECTIVE: We sought to determine if corticosteroid administration is associated with a SARS-CoV-2 nucleic acid test-positive result and to describe therapies administered to SARS-CoV-2 infected children. METHODS: We collected cross-sectional data from participants recruited in 41 pediatric emergency departments (ED) in 10 countries between March 2020 and June 2021. Participants were <18 years old, had signs or symptoms of, or risk factors for acute SARS-CoV-2 infection, and had nucleic acid testing performed. To determine if SARS-CoV-2 test status was independently associated with corticosteroid administration, we used a multivariable conditional logistic regression model matched by study site to compare treatments administered based on SARS-CoV-2 test and disposition status. This analysis was repeated for the subgroup of study participants who were hospitalized. RESULTS: 30.3% (3,121/10,315) of participants were SARS-CoV-2-positive. Although remdesivir was more commonly administered to SARS-CoV-2-positive children, use was infrequent (25/3120 [0.8%] vs 1/7188 [0.01%]; P = .001). Corticosteroid use was less common among SARS-CoV-2-positive children (219/3120 [7.0%] vs 759/7190 [10.6%]; P < .001). Among hospitalized children, there were no differences in provision of inotropes, respiratory support, chest drainage or extracorporeal membrane oxygenation between groups. Corticosteroid administration was associated with age, history of asthma, wheezing, study month, hospitalization and intensive care unit admission; it was not associated with a positive SARS-CoV-2 test result overall (aOR: 0.91; 95%CI: 0.74, 1.12) or among the subgroup of those hospitalized (aOR: 1.04; 95%CI: 0.75, 1.44). CONCLUSIONS: Few disease-specific treatments are provided to SARS-CoV-2-positive children; clinical trials evaluating therapies in children are urgently needed.

SARS-CoV-2 Viral Load Quantification, Clinical Findings and Outcomes in Children Seeking Emergency Department Care: Prospective Cohort Study.

We compared the perfomance of SARS-CoV-2 reverse transcriptase real-time polymerase chain reaction (RT-PCR) to droplet digital PCR (ddPCR). 95% and 40% of positive and negative RT-PCR specimens, respectively, were positive on ddPCR yielding sensitivities of 84% (95% CI: 74, 91) and 97% (95% CI: 89, 99), for RT-PCR and ddPCR, respectively. We found that SARS-CoV-2 RT-PCR testing in children has a concerning false-negative rate at lower nucleocapsid gene copy numbers.

Outcomes of SARS-CoV-2-Positive Youths Tested in Emergency Departments: The Global PERN-COVID-19 Study.

Importance: Severe outcomes among youths with SARS-CoV-2 infections are poorly characterized. Objective: To estimate the proportion of children with severe outcomes within 14 days of testing positive for SARS-CoV-2 in an emergency department (ED). Design, Setting, and Participants: This prospective cohort study with 14-day follow-up enrolled participants between March 2020 and June 2021. Participants were youths aged younger than 18 years who were tested for SARS-CoV-2 infection at one of 41 EDs across 10 countries including Argentina, Australia, Canada, Costa Rica, Italy, New Zealand, Paraguay, Singapore, Spain, and the United States. Statistical analysis was performed from September to October 2021. Exposures: Acute SARS-CoV-2 infection was determined by nucleic acid (eg, polymerase chain reaction) testing. Main Outcomes and Measures: Severe outcomes, a composite measure defined as intensive interventions during hospitalization (eg, inotropic support, positive pressure ventilation), diagnoses indicating severe organ impairment, or death. Results: Among 3222 enrolled youths who tested positive for SARS-CoV-2 infection, 3221 (>99.9%) had index visit outcome data available, 2007 (62.3%) were from the United States, 1694 (52.6%) were male, and 484 (15.0%) had a self-reported chronic illness; the median (IQR) age was 3 (0-10) years. After 14 days of follow-up, 735 children (22.8% [95% CI, 21.4%-24.3%]) were hospitalized, 107 (3.3% [95% CI, 2.7%-4.0%]) had severe outcomes, and 4 children (0.12% [95% CI, 0.03%-0.32%]) died. Characteristics associated with severe outcomes included being aged 5 to 18 years (age 5 to <10 years vs <1 year: odds ratio [OR], 1.60 [95% CI, 1.09-2.34]; age 10 to <18 years vs <1 year: OR, 2.39 [95% CI 1.38-4.14]), having a self-reported chronic illness (OR, 2.34 [95% CI, 1.59-3.44]), prior episode of pneumonia (OR, 3.15 [95% CI, 1.83-5.42]), symptoms starting 4 to 7 days prior to seeking ED care (vs starting 0-3 days before seeking care: OR, 2.22 [95% CI, 1.29-3.82]), and country (eg, Canada vs US: OR, 0.11 [95% CI, 0.05-0.23]; Costa Rica vs US: OR, 1.76 [95% CI, 1.05-2.96]; Spain vs US: OR, 0.51 [95% CI, 0.27-0.98]). Among a subgroup of 2510 participants discharged home from the ED after initial testing and who had complete follow-up, 50 (2.0%; 95% CI, 1.5%-2.6%) were eventually hospitalized and 12 (0.5%; 95% CI, 0.3%-0.8%) had severe outcomes. Compared with hospitalized SARS-CoV-2-negative youths, the risk of severe outcomes was higher among hospitalized SARS-CoV-2-positive youths (risk difference, 3.9%; 95% CI, 1.1%-6.9%). Conclusions and Relevance: In this study, approximately 3% of SARS-CoV-2-positive youths tested in EDs experienced severe outcomes within 2 weeks of their ED visit. Among children discharged home from the ED, the risk was much lower. Risk factors such as age, underlying chronic illness, and symptom duration may be useful to consider when making clinical care decisions.
