Children with cancer often endure a range of psychoneurological symptoms (PNS), including pain, fatigue, cognitive impairment, anxiety, depressive symptoms, and sleep disturbance. Despite their prevalence, the underlying pathophysiology of PNS remains unclear. Hypotheses suggest an interplay between the gut microbiome and the functional metabolome, given the immune, neurological, and inflammatory influences these processes exert.

Article Synopsis
  • Curly top disease is a serious illness that affects sugar beets and is caused by a virus that spreads through a tiny bug called the beet leafhopper.
  • This study shows that the infected beet leafhoppers have more babies but might move around less because the virus changes what happens in their bodies.
  • The research gives new information about how this virus affects the bugs, which could help scientists find better ways to manage the problems caused by curly top disease.

Background: Leukemia and lymphoma (LL) are the most common cancer diagnoses of childhood with high survival rates, but not without impact on the child's functioning and quality of life. This study aimed to use patient-reported data to describe the symptomatic adverse event (AE) experiences among children with LL diagnoses.

Methods: Two hundred and fifty seven children and adolescents aged 7-18 years with a first LL diagnosis completed the Pediatric Patient-Reported version of the Common Terminology Criteria for Adverse Events (Ped-PRO-CTCAE) and Patient-Reported Outcome Measurement Information System (PROMIS) Pediatric measures before starting a treatment course (T1) and after the treatment (T2).

Background: Some children and adolescents receiving chemotherapy experience few symptom-related adverse events, whereas others experience multiple adverse events. If oncology nurses could identify patients likely to have pronounced chemotherapy-related adverse events, tailored supportive care could be matched to these patients' symptom burdens.

Objective: The aim of this study was to identify symptom profiles in children and adolescents before and after chemotherapy, and the sociodemographic and psychological factors associated with profile classification and change.

: Children and adolescents with cancer report increased fatigue and decreased physical activity, introducing risk factors for chronic disease and suppressed quality of life. Research suggests an inverse relationship between fatigue and physical activity, but the biological explanation is not well understood. The purpose of this study was to 1) explore metabolites associated with fatigue or physical activity and 2) to identify any shared metabolomic elements.

Importance: The variability in individual symptom and adverse event reporting between pediatric patient-reports and proxy-reports is widely reported. However, the question of whether symptom profiles based on reports from children with cancer and their caregivers are similar or disparate have not yet been studied.

Objective: To compare proxy symptom reports with patient self-reports to assess alignment.

Background: Despite improvements in survival rates, cancer treatments have significant side effects that affect the quality of life of children and their families. When an ill child cannot self-report symptoms (eg, he or she is too ill), caregiver (parent) reporting becomes critical. This study evaluates the validity and reliability of the caregiver-reported Pediatric Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (Ped-PRO-CTCAE [Caregiver]) measure.

Background: Immunotherapy is a new and promising approach to treating pediatric cancers. These types of therapies have unique mechanisms of action for identifying and fighting cancer, as compared with traditional chemotherapy, and therefore are associated with different therapy-related adverse events (AEs). The purpose of this systematic review was to review available evidence to: (a) identify commonly reported AEs associated with immunotherapy agents frequently used in pediatric oncology and (b) generate recommendations for nursing practice.

Adult survivors of childhood cancer (ASCCs) are at high risk for cardiovascular disease from chemotherapy- and radiation therapy-related cardiotoxicity. Physical activity (PA) can reduce this risk, but the majority of ASCCs do not engage in sufficient PA. The purpose of this study was to identify barriers, facilitators, and resources for PA among ASCCs using the ecological model of physical activity (EMPA) as a theoretical framework.
