Effectiveness of a dose-graded aerobic exercise regimen on cardiopulmonary fitness and physical performance in pediatric survivors of acute lymphoblastic leukemia: a randomized clinical trial

PURPOSE

To determine whether a 12-week supervised dose-graded aerobic exercise (D-GAE) training, when implemented in conjunction with traditional rehabilitation, could help pediatric survivors of acute lymphoblastic leukemia (ALL) enhance their cardiopulmonary capacity and improve their physical performance.

METHODS

Fifty-eight pediatric survivors of ALL (age 13.78 ± 2.47 years; boys 60.34%) were assigned at random to either undergo the D-GAE in addition to the traditional physical rehabilitation (D-GAE group; n = 29) or the traditional physical rehabilitation solely (control group; n = 29). The cardiopulmonary fitness (peak oxygen uptake (VO2peak), ventilatory equivalent (VEq/VO2), minute ventilation (VE, L/min), oxygen pulse (O2P), maximum heart rate (HRmax), 1-min heart rate recovery (HRR1), and respiratory exchange ratio (RER)) and physical performance (6-min walk test (6-MWT), timed up and down stairs (TUDS), and 4 × 10-m shuttle run test (4 × 10mSRT)) were assessed on the pre- and post-intervention occasions.

RESULTS

The mixed-model ANOVA revealed a meaningful increase of VO2peak (P = .002), VE (P = .026), O2P (P = .0009), HRmax (P = .004), and HRR1 (P = .011), and reduction of VEq/VO2 (P = .003) and RER (P = .003) in the D-GAE group compared with the control group. Besides, the analysis detected a favorable increase in the physical performance for the D-GAE group (6-MWT (P = .007), TUDS (P < .001), 4 × 10mSRT (P = .009)).

CONCLUSION

A 12-week D-GAE program in conjunction with traditional rehabilitation holds promise in enhancing cardiopulmonary fitness and improving the physical performance of pediatric survivors of ALL. Clinicians and physical rehabilitation professionals can, therefore, integrate the D-GAE into the traditional rehabilitation protocols for such a patient population to optimize their cardiopulmonary fitness and physical function, while also facilitating a gradual transition to practice and adaption.

IMPLICATIONS FOR CANCER SURVIVORS

The favorable outcomes of this study bolster the inclusion of D-GAE as a crucial element in the care and rehabilitation of pediatric survivors of ALL. By embracing these findings, healthcare professionals and oncologists can contribute to mitigating the long-term cardiopulmonary and physical complications associated with cancer treatments and fostering a state of enhanced well-being and increased physical activity among survivors.

Cancer-Related Fatigue and Daily Living Activities in Pediatric Cancer Survivors

Cancer-related long-term complications such as cardiovascular disease, fatigue, weight-related problems, and emotional disturbances are found to be increased in pediatric cancer survivors (PCSs). The relationship between daily living activities (DLAs) and such complications is still being investigated. Our aim in this study was to investigate the relationship between the cancer-related fatigue and DLA in PCS. Cancer-related fatigue was assessed by "PedsQL Multidimensional Fatigue Scale (MFS)" and "visual analog scale (VAS)." The DLA was evaluated by WeeFIM. There were 77 PCS (44 boys) with a mean age of 10.76 years. The mean value of fatigue scales were VAS 2.48, and MFS total score 71.14. WeeFIM total result was 118.64. While there was a statistically significant relationship between VAS fatigue score and WeeFIM total score ( r=- 0.387; P =0.007), there was no such correlation between WeeFIM total score with MFS total score ( r =0.250; P =0.080). It is established that there is a relationship between level of fatigue and DLA. Risk factors like tumor type or treatment modalities for fatigue should be investigated in larger samples of specific survivor groups. Fatigue and its association with DLA should be screened clinically as a routine surveillance in PCS and treatment options be planned.

Cancer-related fatigue in childhood cancer survivors: A systematic scoping review on contributors of fatigue and how they are targeted by non-pharmacological interventions

OBJECTIVES

We aimed to identify contributors to cancer-related fatigue (CRF), explore non-pharmacological interventions addressing CRF, and highlight which contributors were targeted by these interventions in childhood cancer survivors.

METHODS

We performed a search in various databases and used the PRISMA-ScR checklist. Findings were synthesized in various different tables and figures in accordance with our objectives.

RESULTS

We included 49 articles in this systematic scoping review. We identified 59 significant contributors. Depression and physical activity level were some of the most studied significant contributors. Ten interventional studies were identified (e.g., yoga, physical activity intervention) that addressed 6 contributors (e.g., physical activity level).

DISCUSSION

This review is the first to describe and relate contributors and non-pharmacological interventions targeting CRF in childhood cancer survivors. Important clinical implications could be derived from the variety of factors explaining CRF and how it is currently addressed.

Graded aerobic exercise (GAEx): An effective exercise regimen to improve cardio-respiratory fitness and physical and psychosocial functioning in children with burn sequelae of the chest

PURPOSE

The cardio-respiratory function is compromised in children recovering from burns, particularly, those who sustain a burn injury across the chest, which leads to further prejudicial effects on physical and psychosocial health. This study endeavored to explore the efficacy of 12 weeks of graded aerobic exercise (GAEx) on the cardiorespiratory capacity and physical and psychosocial functioning in children with burn sequelae of the chest.

METHODS

Thirty-six burn-injured children aged 10-18 years (%TBSA: 24.2 ± 4.9, and 38.8 ± 12.9 months since injury) were randomly assigned to GAEx group (n = 18; undergone a 12-week intensity- and time-graded aerobic exercise program plus standard rehabilitation) or control group (n = 18; received the standard rehabilitation only). The cardio-respiratory fitness [marked by the peak oxygen uptake (VO_2peak), minute ventilation (V_E), ventilatory equivalent of inhaled oxygen (VEq/VO₂), oxygen pulse (O₂P), respiratory exchange ratio (RER), maximum heart rate (HR_max), and the heart rate recovery at one minute (HRR₁)] and physical and psychosocial functioning were assessed pre- and post-intervention.

RESULTS

Children in the GAEx group showed significant increases in VO_2peak (P = 0.013), V_E (P = 0.026), O₂P (P = 0.034), HR_max (P = 0.035), and HRR₁ (P = 0.04) and declines in VEq/VO₂ (P = 0.009) and RER (P = 0.011) as compared to the control group. Additionally, the GAEx group reported higher physical (P = 0.029) and psychosocial (P = 0.012) functioning.

CONCLUSION

Twelve weeks of GAEx has salutary effects on cardio-respiratory capacity and physical and psychosocial functioning in children with burn sequelae of the chest. These findings suggest that adding GAEx as a complementary therapy to the long-term rehabilitation protocol for this patient population is worthwhile.

The Impact of a Precision-Based Exercise Intervention in Childhood Hematological Malignancies Evaluated by an Adapted Yo-Yo Intermittent Recovery Test

During cancer treatments in childhood hematological malignancies, reduced exercise tolerance is one of the main hardships. Precision-based training programs help children, adolescents, and young adults and their families to resume regular physical activity, exercise, and sports once they return to their communities after the intensive phases spent in hospital. This study was aimed at verifying whether an intermittent recovery test, the Yo-Yo AD, could provide a simple and valid way to evaluate an individual’s capacity to perform repeated intense exercise and to follow up on the impact of tailored exercise in children, adolescents, and young adults with hematological malignancies. The Yo-Yo AD involved the repetition of several shuttles to muscle exhaustion, at pre-established speeds (walking and slow running). The heart rate (HR) and oxygen saturation (SaO2) were monitored during the test. The total distance and the walking/running ability, measured as the slope of the HR vs. distance correlation, were investigated before (T0) and after 11 weeks (T1) of precision exercise intervention. The Yo-Yo AD was also performed by healthy children (CTRL). Ninety-seven patients (10.58 ± 4.5 years, 46% female) were enrolled. The Yo-Yo AD showed the positive impact of the exercise intervention by increasing the distance covered by the individuals (T0 = 946.6 ± 438.2 vs. T1 = 1352.3 ± 600.6 m, p < 0.001) with a more efficient walking/running ability (T0 = 2.17 ± 0.84 vs. T1 = 1.73 ± 0.89 slope, p < 0.0164). CTRLs performed better (1754.0 ± 444.0 m, p = 0.010). They were equally skillful (1.71 ± 0.27 slope) when compared to the patients after they received the precision-based intervention. No adverse events occurred during the Yo-Yo AD and it proved to be an accurate way of correctly depicting the changes in performance in childhood hematological malignancies.

Aqua-Plyometric Exercises: Potential Implications for Bone Mineral Density, Functional Capacity, and Quality of Life in Survivors of Childhood Acute Lymphoblastic Leukemia

OBJECTIVE

This study endeavored to explore the effect of an aquatic-based plyometric exercise program (Aqua-PLYO) on bone mineralization, functional capacity, and quality of life in survivors of childhood acute lymphoblastic leukemia (ALL).

DATA SOURCES

In a prospective, single-blinded quasi-experimental study, 30 survivors of childhood ALL (63.3% boys; age: 13.1 ± 2.8 years) were allocated to undergo the Aqua-PLYO exercise program (Aqua-PLYO group; n = 15) or the usual physical therapy (Control group; n = 15). Bone mineralization (bone mineral density [BMD], bone mineral content [BMC], BMD Z-score, and BMD volumetric [BMD_vol]), functional capacity, and quality of life were assessed prior to, and following 36 treatment sessions, which were undertaken over nonconsecutive days in a 12-week program. With controlling for the pretreatment values, all measures of bone mineralization, functional capacity, and quality of life showed more favorable posttreatment improvement in the Aqua-PLYO group as compared to the control group (all P < .05).

CONCLUSION

The Aqua-PLYO exercises, besides the usual physical therapy, can effectively improve bone health, increase functional capacity, and promote a better quality of life in long-term survivors of childhood ALL.

IMPLICATIONS FOR NURSING PRACTICE

Although survivors of childhood ALL experience reduced BMD, functional ability, and quality of life, Aqua-PLYO exercises can have positive effects on survivors' physical and functional disturbances and can, even more, be enjoyable and increase their motivation and interest in engaging in exercise interventions.
