The pediatric population seems to be at a lower risk of developing severe clinical symptoms of COVID-19. However, the clinical and epidemiological characteristics of COVID-19 in children are yet to be fully clarified. This retrospective observational study aimed to evaluate the frequency of pediatric laboratory-confirmed COVID-19 patients from February 2020 to April 2021. A total of 740 (5.1% of total) pediatric COVID-19 cases were observed during the study period. The peak of pediatric cases was observed in November 2020, with 239 cases. During the first wave of pandemics, the frequency of pediatric cases was 0.89% (49/5877 cases), ranging from 0.6% in February 2020 to 1.3% in April 2020. On the contrary, after the beginning of the second wave, the frequency of pediatric cases raised from 5.3% in September 2020 to 9.4%in February 2021, with an overall frequency of 8.2% (690/8416 cases). A different rate of SARS-CoV-2 circulation was observed among the pediatric population between the pandemic waves. During the second wave, two peaks of cases were observed. The last peak was associated with the spread of a more transmissive SARS-CoV-2 strain (VOC 202012/01).

Circadian Misalignment Impacts Cardiac Autonomic Modulation in Adolescence.
Sleep
January 2025
Sleep Research & Treatment Center, Department of Psychiatry & Behavioral Health, Penn State University, College of Medicine, Hershey PA, USA.
Study Objectives: Although heart rate variability (HRV), a marker of cardiac autonomic modulation (CAM), is known to predict cardiovascular morbidity, the circadian timing of sleep (CTS) is also involved in autonomic modulation. We examined whether circadian misalignment is associated with blunted HRV in adolescents as a function of entrainment to school or on-breaks.
Methods: We evaluated 360 subjects from the Penn State Child Cohort (median 16y) who had at least 3-night at-home actigraphy (ACT), in-lab 9-h polysomnography (PSG) and 24-h Holter-monitoring heart rate variability (HRV) data.
Interleukin 1 receptor associated kinase 1 gene polymorphism association with risk of rheumatological diseases in Egyptian population.
Mol Biol Rep
January 2025
Pediatric Rheumatology Department, Faculty of Medicine, Cairo University, Cairo, Egypt.
Background: Interleukin-1 receptor-associated kinase1 (IRAK1) plays a considerable role in the inflammatory signaling pathway. The current study aimed to identify any association between (rs1059703) single nucleotide polymorphism (SNP) and vulnerability to rheumatological diseases in the pediatric and adult Egyptian population.
Patients And Methods: The current study included four patient groups: adult Systemic lupus erythematosus (SLE), Rheumatoid arthritis (RA), juvenile systemic lupus erythematosus (JSLE), and juvenile idiopathic arthritis (JIA).
[Clinical sub-phenotypes of acute kidney injury in children and their association with prognosis].

Department of Nephrology and Immunology, Children's Hospital of Soochow University, Suzhou, Jiangsu 215000, China.
Objectives: To investigate the clinical sub-phenotype (SP) of pediatric acute kidney injury (AKI) and their association with clinical outcomes.
Methods: General status and initial values of laboratory markers within 24 hours after admission to the pediatric intensive care unit (PICU) were recorded for children with AKI in the derivation cohort (=650) and the validation cohort (=177). In the derivation cohort, a least absolute shrinkage and selection operator (LASSO) regression analysis was used to identify death-related indicators, and a two-step cluster analysis was employed to obtain the clinical SP of AKI.

Objectives: To investigate the epidemiological characteristics and changing trends of communicable diseases among children and adolescents in China from 1990 to 2021.
Methods: Based on the Global Burden of Disease Database, epidemiological indicators for communicable diseases among the population aged under 20 years in China from 1990 to 2021 were selected to analyze the burden of communicable diseases in this population, and a comparative analysis was performed with global data as well as data from Western Europe and North America.
Results: In 1990-2021, the overall burden of communicable diseases tended to decrease among children and adolescents in China.
Consensus molecular subtyping of colorectal carcinoma brain metastases reveals a metabolic signature associated with poor patient survival.

The transcriptomic classification of primary colorectal cancer (CRC) into distinct consensus molecular subtypes (CMSs) is a well-described strategy for patient stratification. However, the molecular nature of CRC metastases remains poorly investigated. To this end, this study aimed to identify and compare organotropic CMS frequencies in CRC liver and brain metastases.
