Introduction We aimed to examine the impact of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic on diabetic ketoacidosis (DKA) rates in children with type 1 diabetes (T1D). Methods A retrospective cross-sectional study of 11 Israeli pediatric emergency departments (ED) was conducted. Children with T1D who attended the ED between March 1, 2020 and May 31, 2020 were compared with those who attended the ED between March 1, 2019 and May 31, 2019. Results Overall, 150 and 154 children with T1D attended the EDs during the 3-month study periods in 2020 and 2019, respectively. Among patients with established T1D, DKA rates significantly increased in 2020 compared to 2019 [38/64 (59.3%) vs 31/74 (41.9%); p < 0.043]. There was a non-statistically significant trend toward a higher rate of DKA in patients with newly diagnosed T1D [46/86 (53.4%) vs 31/80 (38.7%); p = 0.063]. No differences were observed in the rates of severe DKA in 2020 compared to 2019 among patients with established T1D [10/64 (15.6%) vs 6/74 (8.1%); p = 0.184], and newly diagnosed T1D [16/86 (18.6%) vs 14/80 (17.5%); p = 0.858]. No differences were observed in the rates of intensive care unit admissions in 2020 compared to 2019 among patients with established T1D [14/64 (21.8%) vs 14/74 (18.9%); p = 0.672], and newly diagnosed T1D [26/86 (30.2%) vs 21/80 (26.2%); p = 0.977]. Conclusions Increased rates of DKA in children with established T1D were observed during the first 3 months of the outbreak in Israel. The findings suggest that the severity of DKA at ED presentation in children with T1D was not influenced by the pandemic.

Background: Acute asthma exacerbations are a common cause for emergency department (ED) visits and hospitalizations in children. Since the outbreak of coronavirus disease 2019 (COVID-19) and the education system closure/total lockdown in Israel on March 2020, we have noticed a decrease in pediatric ED visits and an increase in hospitalizations of asthma exacerbations.Objective: to examine the patterns of ED visits for asthma exacerbations during COVID-19 outbreak, in comparison to the previous year.Methods: A retrospective study comparing asthma related ED visits and hospitalizations among children aged 2-18 years at a tertiary center in southern Israel.

Objective We assessed vaccine effectiveness (VE) of BNT162b2 mRNA COVID-19 vaccine against SARS-CoV-2 acquisition among health care workers (HCWs) of long-term care facilities (LTCFs). Methods This prospective study, in the framework of "Senior Shield" program in Israel, included routine, weekly nasopharyngeal SARS-CoV-2 RT-PCR testing from all LTCF HCWs since July 2020. All residents and 75% of HCWs were immunized between December 2020 and January 2021. The analysis was limited to HCWs adhering to routine testing. Fully vaccinated (14+ days after second dose; n=6960) and unvaccinated HCWs (n=2202) were simultaneously followed until SARS-CoV-2 acquisition, or end of follow-up, April 11, 2021. Hazard ratios (HRs) for vaccination vs. no vaccination were calculated (Cox proportional hazards regression models, adjusting for socio-demographics and residential-area COVID-19 incidence). VE was calculated as [(1– HR)×100]. RT-PCR cycle threshold values (Cts) were compared between vaccinated and unvaccinated HCWs. Results At &gt;14 days post second dose, 40 vaccinated HCWs acquired SARS-CoV-2 (median follow-up, 66 days; cumulative incidence 0.6%) vs. 84 unvaccinated HCWs (median follow-up 43 days; cumulative incidence, 5.1%); HR=0.11 (95% CI 0.07, 0.17), unadjusted VE=89% (95% CI 83%, 93%). Adjusted VE beyond seven days and &gt;14 days post second dose were similar. The median PCR Cts targeting ORF1ab gene among 20 vaccinated and 40 unvaccinated HCWs was 32.0 vs. 26.7, respectively, p=0.008. Conclusions VE following two doses of BNT162b2 against SARS-CoV-2 acquisition in LTCF HCWs was high. The lower viral loads among SARS-CoV-2 positive HCWs suggests further reduction in transmission.
