Screen media use, and particularly mobile device use, is frequent among preschool-age children. Studies support that problematic media use (PMU) symptoms are present among older children (4-11-year-olds) and toddlers, and PMU correlates with child temperament and parenting around child media use. We examined the performance of a widely used PMU measure among a sample of 85 3-5-year-old children to document whether variation in PMU exists in this age group and whether this PMU measure specifically has face validity relative to expected correlates of PMU.

Immunosuppression can be withdrawn from selected liver transplant recipients, although robust clinical predictors of tolerance remain elusive. The Immune Tolerance Network ITN056ST study (OPTIMAL; NCT02533180) assessed clinical outcomes and mechanistic correlates of phased immunosuppression withdrawal (ISW) in nonautoimmune, nonviral adult liver transplant recipients. Enrolled subjects were ≥3 years posttransplant with minimal/absent inflammation or fibrosis on a screening liver biopsy.

- The study aimed to investigate how certain genetic factors related to obesity influence children's brain responses to food advertisements after eating.* -
- Researchers analyzed fMRI data from 151 children aged 9-12 and found that a specific genetic variant (rs9939609) was associated with increased brain activity in the lateral hypothalamus in response to food cues, although this result wasn't significant after correcting for multiple comparisons.* -
- The overall conclusion suggests that children with a genetic predisposition to obesity may exhibit stronger brain reward responses to food cues, which might lead to overeating.*
Living donor liver transplantation (LDLT) was first performed in the US in 1989, primarily benefiting pediatric patients. Its adoption for adults faced setbacks after a donor death in 2001, causing widespread risk aversion. Despite ethical justification and demonstrated safety, LDLT remains underutilized, with fewer than 10% of liver transplants being LDLT.

Methods: Children (9-12 years) completed a randomized crossover experiment. During two visits, children ate a preload and then snacks ad libitum while watching television, embedded with food or non-food advertisements to assess eating in the absence of hunger (EAH).
