Article Synopsis
  • Children diagnosed with brain tumors often experience neurocognitive problems, and this study investigates the impacts of post-traumatic stress and sleep on their cognitive abilities.
  • The research included 60 children aged 6-16, who completed questionnaires and neurocognitive tests 51 days after diagnosis, revealing they scored lower in attention, inhibition, and verbal memory compared to age norms.
  • Findings suggest that factors like tumor location and early treatment affect cognitive functioning, but post-traumatic stress and sleep did not show a significant association at this early assessment stage.

Background & Aims: Smell and taste changes are frequently reported bothersome treatment symptoms during treatment for childhood cancer and assumed to influence outcomes such as food intake. Since nutritional status of children with cancer is already vulnerable, any detrimental effects on food intake should be prevented. Therefore, understanding the exact relationship between chemosensory changes and dietary intake, eating behavior, and other domains such as health-related quality of life (HRQoL), is important for improving outcomes.

Article Synopsis
  • The study looked into whether patients change their answers on surveys about their health when they know doctors will read them.
  • Researchers compared two groups of patients: one that knew their answers would be seen by doctors and another that didn't.
  • The results showed no big differences in answers between the two groups, suggesting it's okay for doctors to use these surveys to help understand patients' needs.

Objective: This study examines the association between psychosocial risk and protective factors and a wide range of psychosocial outcomes including emotional, social, cognitive, and physical domains in childhood cancer survivors (CCS).

Methods: CCS from the Dutch Childhood Cancer Survivor Study (DCCSS)-LATER cohort (diagnosed 1963-2001) part 2 (age ≥ 18 years, diagnosed < 18 years, ≥ 5 years since diagnosis) completed questionnaires on psychosocial risk and protective factors (Benefit and Burden Scale, Illness Cognition Questionnaire, Rosenberg Self-Esteem Scale, and Impact of Cancer Scale), and psychosocial outcomes (Hospital Anxiety and Depression Scale, Self-Rating Scale for Post-Traumatic Stress Disorder, TNO-AZL Questionnaire for Adult Health-Related Quality of Life, and Short Form-36). Associations were assessed with regression analysis, adjusting for attained age, sex, number of health conditions, and time since diagnosis, while correcting for multiple testing (p < 0.

Background: Children and adolescents treated for a brain tumor suffer from more fatigue than survivors of other types of childhood cancer. As tumor location might be predictive of fatigue, our aim was to investigate the longitudinal development of fatigue in children with brain tumors and risk factors for fatigue separately for different tumor locations.

Methods: Fatigue was assessed 1235 times for 425 participants.

This study explored the experiences and needs of adolescents, ranging from 12 to 18 years old, who have recently been diagnosed with cancer and participated in a nationwide germline genetic sequencing study within the context of pediatric oncology. The 21 adolescents in this qualitative interview study viewed genetic sequencing as an integral part of their cancer journey. They often characterized germline sequencing as "good-to-know" without specifying immediate utility.
