Respiratory Viral Coinfections in Pediatric Patients in the Primary Care Setting: A Multicenter Prospective Study Within the COPEDICAT Network.

Acute respiratory viral infections pose a significant healthcare burden on the pediatric population globally, but data on the dissemination pattern in the community due to the coronavirus disease 2019 (COVID-19) pandemic are scarce. We conducted a 2-year prospective multicenter study in Catalonia (Spain) that examined the prevalence and coinfection dynamics of respiratory viruses among 1276 pediatric patients from different age groups attending primary care. Coinfection analysis demonstrated complex patterns and revealed a coinfection rate of 23.

Prevalence, Clinical Characteristics and Risk Factors of Post-COVID-19 Condition in a Multicenter Pediatric Primary and Hospital Care Cohort.

The prevalence of post-COVID-19 condition is not well defined. We describe a cohort of 244 children diagnosed with COVID-19 and followed up for 6 months, in which 4.9% of patients had persistent symptoms at 12 weeks.

Household Severe Acute Respiratory Syndrome Coronavirus 2 Transmission and Children: A Network Prospective Study.

Background: The role of children in household transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remains unclear. We describe the epidemiological and clinical characteristics of children with coronavirus disease 2019 (COVID-19) in Catalonia, Spain, and investigate the household transmission dynamics.

Methods: A prospective, observational, multicenter study was performed during summer and school periods (1 July 2020-31 October 2020) to analyze epidemiological and clinical features and viral household transmission dynamics in COVID-19 patients aged <16 years.

Subcutaneous fat distribution in small for gestational age newborns.

We assessed the anthropometric characteristics of symmetric (SGA-S) and asymmetric (SGA-A) term newborns and describe their subcutaneous fat differences. We assessed perinatal data, maternal characteristics and anthropometric variables (including skinfold thicknesses) in 139 small for gestational age (SGA) term infants, classified as symmetric and asymmetric according to their ponderal index (using the 10(th) percentile as the cut-off criterion). Despite an overall small body size and lower amounts of subcutaneous fat than the reference population, SGA-S term newborns showed a proportionate body fat distribution and SGA-A were thinner and had a lower percentage of central subcutaneous fat than SGA-S.

Sedentary behaviour and obesity development in children and adolescents.

Sedentary lifestyle patterns in children and adolescents, i.e. playing digital games, using computers and especially watching television, have been associated with obesity.
