Comparison of febrile seizures in children with or without coronavirus disease-2019: A single-center observational study.

BACKGROUND: Febrile seizure (FS) is one of the most common neurological manifestations of coronavirus disease-2019 (COVID-19) in children. We compared the clinical characteristics of FS in patients with and without COVID-19 during the pandemic period. METHODS: This retrospective single-center study included patients aged 0-18 years who visited the pediatric emergency department (ED) with FS from January 1, 2022, to April 30, 2022. RESULTS: A total of 186 patients visited the pediatric ED with FS during the study period: 123 (66.1%) were positive for COVID-19 and 63 (33.9%) were negative. Patients with COVID-19 were predominantly male (70.7% vs. 50.8%, p = 0.007) and older (2.4 vs. 1.8 years, p = 0.005) than those without COVID-19. A higher proportion of patients with COVID-19 were of atypical age (age > 5 years or <6 months) than those without COVID-19 (26.8% vs. 9.5%, p = 0.006). This was especially true for those aged >5 years (22% vs. 4.8%, p = 0.003). Patients with COVID-19 had a higher probability of multiple episodes of convulsion within 24 h than those without COVID-19 (10.6% vs. 1.6%, p = 0.037). Among patients with COVID-19, males had a shorter fever-to-seizure duration than females (3 h vs. 6.5 h, p = 0.045). CONCLUSIONS: Patients with FS with COVID-19 tend to be predominantly male and have older age of onset than those without COVID-19. Because of the atypical age of onset and probability of multiple convulsion episodes, vigilance for FS is needed in patients with COVID-19, especially males.

Molecular Docking and Molecular Dynamics Simulations Discover Curcumin Analogue as a Plausible Dual Inhibitor for SARS-CoV-2.

Recently, the world has been witnessing a global pandemic with no effective therapeutics yet, while cancer continues to be a major disease claiming many lives. The natural compound curcumin is bestowed with multiple medicinal applications in addition to demonstrating antiviral and anticancer activities. In order to elucidate the impact of curcumin on COVID-19 and cancer, the current investigation has adapted several computational techniques to unfold its possible inhibitory activity. Accordingly, curcumin and similar compounds and analogues were retrieved and assessed for their binding affinities at the binding pocket of SARS-CoV-2 main protease and DDX3. The best binding pose was escalated to molecular dynamics simulation (MDS) studies to assess the time dependent stability. Our findings have rendered one compound that has demonstrated good molecular dock score complemented by key residue interactions and have shown stable MDS results inferred by root mean square deviation (RMSD), radius of gyration (Rg), binding mode, hydrogen bond interactions, and interaction energy. Essential dynamics results have shown that the systemadapts minimum energy conformation to attain a stable state. The discovered compound (curA) could act as plausible inhibitor against SARS-CoV-2 and DDX3. Furthermore, curA could serve as a chemical scaffold for designing and developing new compounds.

Decreased Incidence of Pediatric Intussusception during COVID-19.

Coronavirus disease 2019 (COVID-19) changed the epidemiology of various diseases. The present study retrospectively investigates the epidemiologic and clinical changes in pediatric intussusception for ages ≤ 7 years before (February 2019-January 2020) and after (February 2020-January 2021) the COVID-19 outbreak in a single pediatric emergency department of a university-affiliated tertiary hospital. The incidence of communicable diseases-defined as infectious diseases with the potential for human-to-human transmission via all methods, non-communicable diseases, and intussusception were decreased following the COVID-19 outbreak (15,932 to 3880 (24.4%), 12,994 to 8050 (62.0%), and 87 to 27 (31.0%), respectively). The incidence of intussusception correlated significantly with the change in incidence of communicable diseases (Poisson log-linear regression, odds ratio = 2.15, 95% CI = 1.08-4.26, and p = 0.029). Compared with the pre-pandemic period, patients of the pandemic period showed higher proportions of pathologic leading point (PLP) and hospitalization (14.8% vs. 2.3% and 18.5% vs. 4.6%, respectively), lower base excesses (-4.8 mmol/L vs. -3.6 mmol/L), and higher lactate concentrations (1.7 mmol/L vs. 1.5 mmol/L). The incidence of pediatric intussusception decreased after the COVID-19 pandemic. This reduced incidence may be related to the reduced incidence of communicable diseases. However, the proportions of more severe diseases and PLPs were higher after the COVID-19 pandemic.
