Effects of Exercise Interventions on Immune Function in Children and Adolescents With Cancer and HSCT Recipients - A Systematic Review

Health-Related Quality of Life and Mental Health of Parents of Children with Pediatric Abdominal Tumors

BACKGROUND

Abdominal tumors rarely occur in childhood but are associated with great psychological stress for patients and their families. Parents playing a central role in their children's treatment may experience adverse effects on their Health-Related Quality of Life (HRQoL) and mental health due to the children's illness and required treatment. Given the limited knowledge of the psychosocial burden of parents with children suffering from solid abdominal tumors, this study aims to assess their HRQoL and mental health along with the impact of various psychosocial factors.

METHODS

A cross-sectional cohort study was carried out involving 54 parents of children with solid abdominal tumors who had surgery at the University Medical Center Hamburg-Eppendorf in Germany. The results were compared with 46 parents of children undergoing routine surgeries without a prior tumor diagnosis, and with normative values. Data were obtained using standardized questionnaires.

RESULTS

Parents of the index group showed significantly worse HRQoL and limited mental health. Furthermore, they showed significantly higher parental burden in several subscales and less social support in comparison with the control group.

CONCLUSIONS

Considering the lower parental HRQoL and the central role parents play in their children's lives, it is crucial to include prevention and intervention measures for parents as part of a multimodal treatment regime for children with solid pediatric abdominal tumors.

Factors That Influence Physical Activity Behavior in Children and Adolescents During and After Cancer Treatment: A Qualitative Systematic Review of the Literature

PURPOSE

The aim of this systematic review is to reveal the social, personal, and contextual factors that influence physical activity (PA) in children and adolescents during and after cancer treatment.

METHOD

SPORTDiscus, Cochrane, Web of Science, PubMed, and FIS Education electronic database were systematically searched.

RESULTS

The 13 included studies show that social support (parents, siblings, and friends) in particular is rated as important by cancer survivors; for example, doing PA together. Depending on the treatment status and state of health, particularities arise. During the acute treatment phase, parents issued more prohibitions regarding PA than after treatment. The state of health and concern about infections are described as inhibiting factors. Not all hospitals generally offer special exercise programs for cancer patients, and in some cases, only sporadic exercise sessions were conducted by specialized staff. In addition, the hospital atmosphere, such as cramped rooms, tends to be associated with demotivating effects.

CONCLUSIONS

Both inhibiting and promoting factors in the area of social, personal, and contextual factors could be identified. The most fundamental factor for PA is the physical condition. Social factors, such as parents or friends, often have a motivating effect and can promote PA. Inhibiting factors are mainly context-related, such as an environment unsuitable for PA. Although the review highlights interesting aspects, further treatment-related and longitudinal studies could provide deeper insights.

Pediatric oncohematological exercise program in hospital: clinical trial study protocol

Leukemias are the most common types of hematological cancers in children, and negatively impact functional capacity. There is evidence in the literature that therapeutic exercises can have a positive impact on functions. The aim of this study is to evaluate functional capacity, muscle strength, fatigue and quality of life through the application of a protocol of therapeutic exercises during pediatric leukemia hospitalization. Children will be allocated into two groups: one will carry out a protocol of therapeutic exercises, while the other will undergo conventional respiratory physiotherapy. The protocol is approved by the ethics and research committee of the host institution (No. 5.439.594). Results will be disseminated through peer-reviewed journal articles and conferences. Clinical trial registration: RBR-8sxnfyd (https://ensaiosclinicos.gov.br).

Exercise Preferences in Young Adults with Cancer-The YOUEX Study

(1) Background: Strong evidence supports the persuasive positive effects of exercise for cancer patients and survivors. Different approaches of exercise programs have been established; however, the special interests of young adults (YAs) with cancer have rarely been considered in exercise interventions. Therefore, the study YOUng EXercisers (YOUEX) aimed to investigate exercise preferences in YAs. (2) Methods: YOUEX was a three-arm, patient preference-based non-randomized, longitudinal, pre-post exercise intervention, offering three different exercise modules to YAs during or after acute therapy (Module 1: online supervised group-based (M1); Module 2: online unsupervised (M2); Module 3: in-person supervised (M3)). The intervention period was 12 weeks with another 12-week follow-up period, the modules could be changed or amended after 6 and 12 weeks. (3) Results: 92 YAs were allocated to the study. At baseline, 50 YAs (54%) chose M2, 32 YAs (35%) M1 and 10 YAs (11%) M3. The analysis revealed high acceptability and feasibility of the online exercise programs (M1, M2). There was a high impact of the COVID-19 pandemic on the execution of M3. YAs showed diverse preferences in module selection due to differences in, e.g., cancer therapy status or favored level of supervision. (4) Conclusions: YAs need personalized exercise programs that consider their individual interests and needs. Online exercise programs can be a promising addition to existing exercise opportunities. They are an effective way to increase physical activity levels in YAs.

Psychological Effects of a Structured Exercise Intervention During Umbilical Cord Blood Transplantation in Children and Adolescents

BACKGROUND

Children and adolescents undergoing umbilical cord blood transplantation (UCBT) are faced with severe fatigue and a decline in quality of life (QoL) during the inpatient period.

OBJECTIVE

To investigate the effect of a structured exercise intervention on fatigue, QoL and clinical outcomes among children and adolescents during UCBT.

METHODS

In this randomized controlled trial, participants (n = 48) were randomized to a control group (CG: usual care) or an intervention group (IG: a structured exercise intervention). Fatigue and QoL were assessed at hospital admission, 14 days after UCBT, and at discharge using linear mixed model analysis. In addition, engraftment kinetics, supportive treatment, transplant-related complications, and hospital length of stay were derived from medical records.

RESULTS

4 patients completed the study, the IG participated in an average of 2.12 (1.36-2.8) sessions with a duration of 24 (16-34) min weekly, and the total rate of adherence to the training program was 70.59%. For fatigue and QoL, there was a significant effect of time in the control group, with the total score of fatigue decreased from T1 to T2 (73.9vs 60.9, P = .001) and T1 to T3 (73.9vs 65.6, P = .049), and the QoL scores decreased from T1 to T2 (73.9vs 66.1, P = .043). The hospital length of stay was less in the intervention group (P = .034).

CONCLUSION

Our randomized study indicated that structured exercise interventions might exert a protective effect by attenuating the decline in fatigue and QoL, and shortening duration of hospitalization.

Therapeutic exercise interventions in pediatric survivors of brain cancer and other solid tumors: A scoping review

Background

Improved survival rates for children with solid tumors presents an ongoing challenge of how to maximize quality of survivorship and effectively manage the short- and long-term complications of disease and treatment. To gain an understanding of the extent and nature of research pertaining to therapeutic exercise interventions and identify knowledge gaps, we conducted a scoping review of exercise training studies conducted in pediatric survivors of brain cancer and other solid tumors.

Method

A systematic literature search was performed across four electronic databases. Papers were selected for full-text review if they included participants treated for brain cancer or other solid tumors, with at least 50% of participants aged ≤ 21 years, evaluated an exercise intervention ≥2-weeks in duration, and were published in an English, peer-reviewed journal. We included the following quantitative study designs; randomized controlled trials, non-randomized trials, and single-arm pre-test-post-test.

Results

Of the 7,482 citations identified, 17 papers met the inclusion criteria (presenting findings from eleven studies). Two studies were randomized controlled trials, five studies were non-randomized controlled trials, and four studies were a single-arm pre-test post-test design. Average age of participants ranged from 7.3-15.5 years, and time since diagnosis ranged from 3 to 70 months. Five studies included participants with brain tumors exclusively, three studies included other solid tumors, and three studies included a mixed sample (brain and other solid tumors). A wide range of exercise modalities were employed, including cycle ergometry, resistance training, sport, yoga, and active gaming. The length of the exercise program ranged from 3-40 weeks and frequency from 3-11 sessions per week. Exercise session duration ranged from 15-180 min, with most studies reporting 30-90-min sessions. Adherence ranged from 77 to 100%, with none of the studies reporting adverse events. Studies reported improvements in cardiorespiratory fitness, functional strength, physical activity, and quality of life.

Conclusions

A small number of mostly low methodological quality studies have examined the effects of therapeutic exercise in pediatric survivors of solid tumors. Although limited, the extant literature supports the feasibility and safety of therapeutic exercise interventions for pediatric survivors of brain cancer and other solid tumors.

Osteoporosis in Childhood Cancer Survivors: Physiopathology, Prevention, Therapy and Future Perspectives

The improvement of chemotherapy, radiotherapy, and surgical interventions, together with hematopoietic stem cell transplantation, increased childhood cancer survival rate in the last decades, reaching 80% in Europe. Nevertheless, anti-cancer treatments are mainly responsible for the onset of long-term side effects in childhood cancer survivors (CCS), including alterations of the endocrine system function and activity. In particular, the most frequent dysfunction in CCS is a metabolic bone disorder characterized by low bone mineral density (BMD) with increased skeletal fragility. BMD loss is also a consequence of a sedentary lifestyle, malnutrition, and cancer itself could affect BMD, thus inducing osteopenia and osteoporosis. In this paper, we provide an overview of possible causes of bone impairment in CCS in order to propose management strategies for early identification and treatment of skeletal fragility in this population.
