EFFECTS OF PHYSICAL EXERCISE DURING HOSPITALIZATION IN CHILDREN AND ADOLESCENTS WITH CANCER: A SYSTEMATIC REVIEW

Physical Activity Intervention Characteristics and Effects on Behavioral and Health-Related Outcomes Among Adolescents and Young Adults Living with and Beyond Cancer: A Systematic Review

Participation in physical activity (PA) during and after cancer treatment is safe and beneficial in the adolescent and young adult (AYA) cancer population. PA can positively impact health-related outcomes; however, participation remains low. This systematic review aims to describe PA intervention characteristics and outcomes in AYA survivors of cancer (AYASCa). This review followed Preferred Reporting Index for Systematic Reviews and Meta Analyses (PRISMA) guidelines and was registered with Prospero (CRD42022365661). PubMed, CINAHL, and Scopus databases were searched for randomized control trials (RCTs) and pre/post-test studies without a control group through December 31, 2022. Data included: participant demographics, PA intervention characteristics, and health-related outcomes. Studies were assessed using the National Institute of Health Critical Appraisal Tools, and findings were synthesized to identify common characteristics of PA interventions and outcomes. Twenty-three studies were included: 15 RCTs and 8 pre/post-test studies. Heterogeneity existed across design, sample demographics, intervention timing, and observed outcomes. The most common characteristics of PA interventions were supervision of PA, wearable device use, tailored/individualized PA prescriptions, and goal setting. PA interventions positively affected health-related outcomes, with 21 studies reporting statistically significant findings. Implementing personalized PA prescriptions, utilizing wearable devices, and incorporating goal setting as characteristics in PA interventions hold potential benefits for AYASCa, leading to improved outcomes. Still, additional research is needed to explore interventions that utilize these PA characteristics and determine which ones are most effective for AYASCa. By further investigating and identifying optimal PA characteristics, interventions can be better tailored to meet this population's specific needs and preferences, ultimately enhancing their overall well-being and recovery.

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.

Effects of Exercise and Physical Activity Levels on Childhood Cancer: An Umbrella Review

Patients and survivors of childhood cancer experience adverse effects related to the disease and its treatment. These adverse effects are associated with both physiological and psychological health. Exercise helps manage the side effects and improve the health outcomes. The objective of this umbrella review is to search the current literature in the context of exercise and physical activity as complementary interventions on pediatric cancer and to provide comprehensive information about the derived health outcomes. A literature search was conducted on the Cochrane, PubMed, and Embase databases for systematic reviews published up to January 2023. Moreover, a hand search of reference lists was performed. We included participants under 19 years of age at diagnosis of any type of childhood cancer, without restriction on the type or phase of treatment, who participated in exercise interventions. The results showed a beneficial impact on fatigue, muscle strength, aerobic capacity, activity and participation levels, psychosocial health, cardiovascular/cardiorespiratory fitness, physical function, bone mineral density, and brain volume and structure, with limited and not serious adverse effects. These findings documented that exercise interventions had a positive effect on many physiological and psychological health outcomes in pediatric cancer patients and survivors.

The use of virtual reality in the stimulation of manual function in children with cerebral palsy: a systematic review

OBJECTIVE

To identify in national and international literature the use of virtual reality to develop manual skills of children with cerebral palsy.

METHODS

This is a systematic review carried out in the PubMed database, Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), and the Online System for Search and Analysis of Medical Literature (Ovid Medline) using the keywords "cerebral palsy", "virtual reality", "occupational therapy", "child", "daily activities/activities of daily living", in English and in Portuguese. The selected articles had their methodological quality evaluated through the Physiotherapy Evidence Database (PEDro scale).

RESULTS

228 studies were selected, as they included children with cerebral palsy undergoing treatment with exposure to virtual reality to improve manual function in daily activities. Studies on other themes, incomplete, and duplicated reviews were excluded. Three evaluators conducted the study selection process and included 14 articles in the analysis.

CONCLUSIONS

The findings suggest that virtual reality therapy has contributed to an improvement in the manual function of children with cerebral palsy, constituting a useful resource for a supporting intervention to enhance traditional therapies.

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.

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

Background

Pediatric cancer patients are at high risk for life-threatening infections, therapy associated complications and cancer-related side effects. Exercise is a promising tool to support the immune system and reduce inflammation. The primary objective of this systematic review was to evaluate the effects of exercise interventions in pediatric cancer patients and survivors on the immune system.

Methods

For this systematic review (PROSPERO ID: CRD42021194282) we searched four databases (MEDLINE, Cochrane Library, ClinicalTrials.gov, SPORTDiscus) in June 2021. Studies with pediatric patients with oncological disease were included as main criterion. Two authors independently performed data extraction, risk of bias assessment, descriptive analysis and a direction ratio was calculated for all immune cell parameters.

Findings

Of the 1448 detected articles, eight studies with overall n = 400 children and adolescents with cancer and n = 17 healthy children as controls aged 4-19 years met the inclusion criteria. Three randomized, four non-randomized controlled trials and one case series were analyzed descriptively. The exercise interventions had no negative adverse effects on the immune system. Statistically significant results indicated enhanced cytotoxicity through exercise, while changes in immune cell numbers did not differ significantly. Interventions further reduced days of in-hospitalization and reduced the risk of infections. Several beneficial direction ratios in immune parameters were identified favoring the intervention group.

Interpretation

Exercise interventions for pediatric cancer patients and survivors had no negative but promising beneficial effects on the immune system, especially regarding cytotoxicity, but data is very limited. Further research should be conducted on the immunological effects of different training modalities and intensities, during various treatment phases, and for different pediatric cancer types. The direction ratio parameters given here may provide useful guidance for future clinical trials.
