Debates Around the Role of School Closures in the Coronavirus 2019 Pandemic-Reply

Adenomesenteritis following SARS-CoV-2 Vaccination in Children: A Case Report and Review of The Literature

At present, the vaccine authorized in children aged 5 years and older is the BNT162b2 messenger RNA COVID-19 vaccine. Unlike adults, there is limited data available in the pediatric age describing adverse events after vaccine. We report a case of adenomesenteritis in a young girl following the first dose of vaccine.

Childhood Cancer Survivors and Distance Education Challenges: Lessons Learned From the COVID-19 Pandemic

OBJECTIVE

Pediatric cancer survivors have historically struggled to receive adequate educational supports. In Spring 2020, the COVID-19 pandemic forced an emergency switch from traditional in-person education models to distance education, but little information is available regarding experiences of pediatric survivors' coping with schooling since that time.

METHODS

This article presents exploratory mixed methods findings from a quality improvement project including qualitative interviews and a quantitative survey conducted with parents of pediatric oncology survivors identified through neuropsychological assessment, and the use of school-based services as having educationally relevant neurocognitive impacts of disease or treatment. The interviews explored experiences of education and instructional delivery during the COVID-19 school closures in spring of 2020 and the beginning of the 2020-2021 school year and served as the foundation for a quantitative survey to determine the generalizability of findings.

RESULTS

Qualitative interviews highlighted 3 emergent themes regarding the shared experiences of distance schooling for children with cancer during the COVID-19 school closures: (a) attention, (b) mental health, and (c) access to instruction. A follow-up quantitative survey supported the qualitative findings and their generalizability to the schooling experiences of other children with cancer during the pandemic.

CONCLUSION

This article describes and explores each theme and offers suggestions for pediatric supports and changes to provider service delivery (including weblinks to access project-developed resources) as a result of ongoing pandemic-related schooling needs.

SARS-CoV-2 Molecular Transmission Clusters and Containment Measures in Ten European Regions during the First Pandemic Wave

Background: The spatiotemporal profiling of molecular transmission clusters (MTCs) using viral genomic data can effectively identify transmission networks in order to inform public health actions targeting SARS-CoV-2 spread. Methods: We used whole genome SARS-CoV-2 sequences derived from ten European regions belonging to eight countries to perform phylogenetic and phylodynamic analysis. We developed dedicated bioinformatics pipelines to identify regional MTCs and to assess demographic factors potentially associated with their formation. Results: The total number and the scale of MTCs varied from small household clusters identified in all regions, to a super-spreading event found in Uusimaa-FI. Specific age groups were more likely to belong to MTCs in different regions. The clustered sequences referring to the age groups 50–100 years old (y.o.) were increased in all regions two weeks after the establishment of the lockdown, while those referring to the age group 0–19 y.o. decreased only in those regions where schools’ closure was combined with a lockdown. Conclusions: The spatiotemporal profiling of the SARS-CoV-2 MTCs can be a useful tool to monitor the effectiveness of the interventions and to reveal cryptic transmissions that have not been identified through contact tracing.

Assessment of Respiratory Function in Infants and Young Children Wearing Face Masks During the COVID-19 Pandemic

IMPORTANCE

Face masks have been associated with effective prevention of diffusion of viruses via droplets. However, the use of face masks among children, especially those aged younger than 3 years, is debated, and the US Centers for Disease Control and American Academy of Physicians recommend the use of face mask only among individuals aged 3 years or older.

OBJECTIVE

To examine whether the use of surgical facial masks among children is associated with episodes of oxygen desaturation or respiratory distress.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study was conducted from May through June 2020 in a secondary-level hospital pediatric unit in Italy. Included participants were 47 healthy children divided by age (ie, group A, aged ≤24 months, and group B, aged >24 months to ≤144 months). Data were analyzed from May through June 2020.

INTERVENTIONS

All participants were monitored every 15 minutes for changes in respiratory parameters for the first 30 minutes while not wearing a surgical face mask and for the next 30 minutes while wearing a face mask. Children aged 24 months and older then participated in a walking test for 12 minutes.

MAIN OUTCOMES AND MEASURES

Changes in respiratory parameters during the use of surgical masks were evaluated.

RESULTS

Among 47 children, 22 children (46.8%) were aged 24 months or younger (ie, group A), with 11 boys (50.0%) and median (interquartile range [IQR]) age 12.5 (10.0-17.5) months, and 25 children (53.2%) were aged older than 24 months to 144 months or younger, with 13 boys (52.0%) and median (IQR) age 100.0 (72.0-120.0) months. During the first 60 minutes of evaluation in the 2 groups, there was no significant change in group A in median (IQR) partial pressure of end-tidal carbon dioxide (Petco2; 33.0 [32.0-34.0] mm Hg; P for Kruskal Wallis = .59), oxygen saturation (Sao2; 98.0% [97.0%-99.0%]; P for Kruskal Wallis = .61), pulse rate (PR; 130.0 [115.0-140.0] pulsations/min; P for Kruskal Wallis = .99), or respiratory rate (RR; 30.0 [28.0-33.0] breaths/min; P for Kruskal Wallis = .69) or for group B in median (IQR) Petco2 (36.0 [34.0-38.0] mm Hg; P for Kruskal Wallis = .97), Sao2 (98.0% [97.0%-98.0%]; P for Kruskal Wallis = .52), PR (96.0 [84.0-104.5] pulsations/min; P for Kruskal Wallis test = .48), or RR (22.0 [20.0-25.0] breaths/min; P for Kruskal Wallis = .55). After the group B walking test, compared with before the walking test, there was a significant increase in median (IQR) PR (96.0 [84.0-104.5] pulsations/min vs 105.0 [100.0-115.0] pulsations/min; P < .02) and RR (22.0 [20.0-25.0] breaths/min vs 26.0 [24.0-29.0] breaths/min; P < .05).

CONCLUSIONS AND RELEVANCE

This cohort study among infants and young children in Italy found that the use of facial masks was not associated with significant changes in Sao2 or Petco2, including among children aged 24 months and younger.
