Excessive screen time in children is linked to obesity, overweight, sedentary behavior, depression and mood disorders, myopia, behavioral changes, sleep disturbances, attention deficit hyperactivity disorder, among others. Polymorphisms in genes like FTO, CACNA1D, and DRD2 could further increase these risks. Implementing strategies such as limiting screen use, creating screen-free zones, and monitoring content is essential to mitigate adverse physical and mental health effects in the pediatric population.

To prevent respiratory syncytial virus (RSV)-associated lower respiratory tract infections, a single dose of nirsevimab, a long-acting monoclonal antibody, is recommended for all neonates born during the RSV season (October to March) and all infants younger than 6 months old at the start of the RSV season. Nirsevimab should be administered shortly after birth to neonates and just before or early in the season to infants entering their first RSV season.

-
This study assessed the effects of vitamin C on children with community-acquired pneumonia (CAP). Vitamin C supplementation improved clinical symptoms within 48–72 hours compared to placebo but did not reduce the length of hospital stay (LOS). These findings suggest that vitamin C is beneficial for managing CAP severity, but does not affect LOS.

Question: Do macrophage migration-inhibitory factor (MIF) and growth differentiation factor-15 (GDF-15) levels and their gene polymorphisms affect RDS among preterm babies?
Finding: Significantly higher serum MIF and GDF-15 levels were observed in patients with severe respiratory distress syndrome (RDS). The mutant G- and C-alleles of GDF-15 rs4808793 C>G single nucleotide polymorphism (SNP) and MIF rs755622 G>C SNP were present at significantly higher frequencies in preterm neonates with RDS.
Meaning: MIF and GDF-15 play a significant role in neonatal RDS and its severity.

Question: Could hematopoietic stem cell transplantation (HSCT) be an alternative to enzyme replacement therapy (ERT) for type VI mucopolysaccharidosis (MPS VI)?
Finding: HSCT is generally not offered due to reports of high toxicity and mortality. However, we detected fewer complications and graft-versus-host disease cases and no deaths with HSCT.
Meaning: HSCT is both less expensive than ERT and permanent; thus, it should be considered an alternative treatment for MPS VI.

CO2 insufflation has been used instead of air insufflation to reduce postprocedure pain and discomfort in adults; however, adequately powered studies in children are scarce. This randomized controlled trial of 200 children showed that CO2 insufflation reduces postprocedure pain and discomfort during pediatric colonoscopy with no signs of CO2 retention. CO2 insufflation is safe and causes less pain in children.

Myopia is a growing global public health concern because of its association with irreversible vision loss such as myopic traction maculopathy, rhegmatogenous retinal detachment, and glaucoma. The effective prevention of myopia in childhood requires a multidisciplinary approach that integrates ophthalmologic care with lifestyle, nutrition, and sleep interventions. Early detection through regular visual screening in schools and primary care settings and timely ophthalmology referrals are critical to preventing high myopia.

Myopia is a major ophthalmological disorder with increasing prevalence worldwide, particularly in East Asia. Evidence indicates that its development involves complex interactions between genetic and environmental factors. Body stature, sleep patterns, and nutritional status significantly influence the progression of myopia during childhood and adolescence. Its treatment and prevention strategies include optical correction, atropine therapy, increased outdoor activity, decreased near work, and regular retinal monitoring.
