Safety and feasibility of physical therapy in cytopenic patients during allogeneic haematopoietic stem cell transplantation

Assessment of rehabilitation practices during hematopoietic stem cell transplantation in the United States: a survey

Background

Rehabilitation therapy is important to treat physical and functional impairments that may occur in individuals receiving physically taxing, yet potentially curative hematopoietic stem cell transplants (HSCT). However, there is scarce data on how rehabilitation is delivered during HSCT in real-life setting. Our objective is to assess the rehabilitation practices for adult patients hospitalized for HSCT in the United States.

Methods

A 48-question online survey with cancer centers with the top 10% HSCT volumes (per American registries). We obtained data on patient characteristics, rehabilitation therapy details (timing, indication, administering providers), physical function objective and subjective outcome measures, and therapy activity precautions.

Results

Fourteen (out of 21) institutions were included. Rehabilitation therapy referrals occurred at admission for all patients at 35.7% of the centers for: functional decline (92.9%), fall risk (71.4%), and discharge planning (71.4%). Participating institutions had physical therapists (92.9%), occupational therapists (85.7%), speech language pathologists (64.3%) and therapy aides (35.7%) in their rehabilitation team. Approximately 71% of centers used objective functional measures including sit-to-stand tests (50.0%), balance measures (42.9%), and six-minute walk/gait speed (both 35.7%). Monitoring of blood counts to determine therapy modalities frequently occurred and therapies held for low platelet or hemoglobin values; but absolute neutrophil values were not a barrier to participate in resistance or aerobic therapies (42.9%).

Discussion

Rehabilitation practices during HSCT varied among the largest volume cancer centers in the United States, but most centers provided skilled therapy, utilized objective, clinician and patient reported outcomes, and monitored blood counts for safety of therapy administration.

Inpatient Rehabilitation of Hematopoietic Stem Cell Transplant Patients: Managing Challenging Impairments and Medical Fragility

ABSTRACT

Hematopoietic stem cell transplants play an important role in the treatment of cancer, particularly hematologic malignancies. These patients can encounter functional impairments unique to hematopoietic stem cell transplant, including deconditioning, cancer-related fatigue, steroid myopathy, graft versus host disease, and capillary leak syndrome. Medical fragility and increased risk of infection may make rehabilitation challenging on the acute care and postacute care settings. Patients admitted to acute inpatient rehabilitation experience a high rate of transfer to the primary acute service and high rate of mortality after transfer back. Physical medicine and rehabilitation physicians can use a number of strategies to mitigate these patients' risk of medical complications including evidence-based predictive models to assist with postacute rehabilitation triage, physiatry-led consult-based rehabilitation, and oncology hospitalist comanagement on inpatient rehabilitation.

Minimal important difference of the 6-minute walk test after allogenic hematopoietic stem cell transplantation

PURPOSE

The 6-min walk test (6MWT) of allogenic hematopoietic stem cell transplantation (allo-HSCT) recipients has been gaining attention; however, minimal differences have not been reported. This study aimed to determine the minimal important difference (MID) in the 6MWT among hospitalized patients with allo-HSCT.

MATERIALS AND METHODS

The MID of the 6MWT was calculated using three different methodologies based on an anchor-based method; basic anchor-based methods, linear regression analysis, and receiver operating characteristic (ROC) curve analysis. The decrease in the score of Question 2 of the European Organization for Research and Treatment of Cancer Quality of life questionnaire core-30 was included as an anchor question for calculating the MID. Both actual and percentage changes in 6MWT values from baseline and at discharge were used in the MID calculations. In the actual and percentage change of the 6MWT, the one with the larger the area under the curve in the ROC curve was recommended as the MID.

RESULTS

Among the three methods using actual values, the largest MID of the 6MWT was -37.5 m (sensitivity: 54%, specificity: 88%).

CONCLUSION

More careful follow-up after discharge is necessary for allo-HSCT patients who show a reduction of 37.5 m or more in the acute illness phase.

Effects of continuous bicycle ergometer and step exercises from admission to discharge in a patient with myelodysplastic syndrome undergoing myeloablative conditioning and hematopoietic stem cell transplantation: A case report

BACKGROUND

In myelodysplastic syndromes (MDS), in addition to disease-related symptoms, many adverse events are associated with anticancer agents, myeloablative conditioning (MAC), and allogeneic hematopoietic stem cell transplantation (allo-HSCT). Isolation and bed rest in a clean room severely limit physical activity, resulting in cardiopulmonary and muscle weakness. In addition, post-transplant patients may experience general fatigue, gastrointestinal symptoms, and infections associated with a weakened immune system, as well as graft-versus-host disease, which causes further decline in physical function and activities of daily living (ADL). Most reports on the rehabilitation of patients with hematopoietic tumors involve interventions before and after chemotherapy or transplantation. However, an important issue is to establish effective and feasible exercise programs in a clean room setting, where activity is severely limited and physical function is most likely to decline.

CASE REPORT

This case report describes the treatment progress of a 60-year-old man with MDS and thrombocytopenia scheduled to receive MAC and allo-HSCT, who continued bicycle ergometer and step exercises from admission to discharge. The patient was admitted for allo-HSCT, and on day 4, he started bicycle ergometer and step exercise in a clean room and continued until discharge. As a result, exercise tolerance and lower-extremity muscle strength were maintained at the time of hospital discharge. Furthermore, the patient was able to continue rehabilitation in a restricted environment without adverse events.

CONCLUSIONS

The rehabilitation and treatment course of this case may provide valuable information for patients with MDS and thrombocytopenia.

Evaluation of a group-based exercise and relaxation rehabilitation program during hospitalization for allogeneic hematopoietic stem cell transplant

BACKGROUND

Exercise and relaxation interventions have demonstrated benefits in allogeneic hematopoietic stem cell transplant (allo-HSCT) patients; however, little is known about the implementation enablers and barriers for inpatient rehabilitation or its impact on health outcomes.

OBJECTIVE

To conduct a program evaluation of group-based rehabilitation consisting of exercise and relaxation classes for allo-HSCT inpatients.

DESIGN

Prospective program evaluation using the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework.

SETTING

Inpatient hospital unit at a tertiary care center.

PARTICIPANTS

Forty-five adult patients admitted for allo-HSCT.

INTERVENTIONS

Standard of care rehabilitation.

MAIN OUTCOME MEASURES

Program attendance, safety, satisfaction, and fidelity were assessed. Exploratory effectiveness analyses were conducted via the measurement of physical, psychosocial, clinical, and health resource use outcomes at hospital admission and discharge.

RESULTS

Forty-seven of the 63 patients receiving allo-HSCT between November 2019 and March 2020 were consented. Data presented in this publication are from the 33 participants who completed study assessments (high attrition due to cancellation of research during the COVID-19 pandemic). Eighty-two percent of participants attended at least one class; however, 55% of the participants invited to the classes on a daily basis were not able to attend. Barriers to participation included transplant complications, isolation for infection prevention, and fatigue. There were no adverse events associated with the intervention and 82% of participants adhered to the prescribed activities. Participants reported satisfaction with the program and enjoyed the motivational support and social interaction. Between hospital admission and discharge, anxiety scores improved; however, fatigue, depression, grip strength, functional mobility, and quality of life scores declined. Physical activity volume and lower body strength were maintained.

CONCLUSIONS

Group-based exercise and relaxation classes seem to be feasible and safe during hospitalization for allo-HSCT; however, there are pragmatic barriers to be considered for optimal program implementation. Further research examining program effectiveness and adoption is warranted.

Pain, Fatigue, Nausea, and Vomiting as the Predictors of Anxiety in Patients Undergoing Hematopoietic Stem Cell Transplantation: A Prospective Cohort Study

The primary outcome was to assess the correlation between anxiety and pain, fatigue, nausea, and vomiting. The secondary outcome was to determine the predictive roles of pain, fatigue, nausea, and vomiting in anxiety among patients undergoing Hematopoietic Stem Cell Transplantation (HSCT). The present prospective cohort study was conducted on 200 patients treated by HSCT referred to the centers affiliated to Shiraz University of Medical Sciences. The data were collected using Spielberger Anxiety Questionnaire, Numerical Pain Scale, Brief Fatigue Inventory, and Rhodes Nausea and Vomiting Index. The data were analyzed using Spearman’s test and multiple regression analysis. The means of state anxiety, trait anxiety, pain, fatigue, and nausea, vomiting, and retching were 41.67 (SD = 9.71), 43.78 (SD = 9.00), 3.79 (SD = 2.79), 4.23 (SD = 2.48), and 6.31 (SD = 7.53), respectively. The results showed that the participants with higher pain and fatigue scores had higher anxiety levels. Those with more nausea and vomiting had higher anxiety levels, as well. This indicated that fatigue, pain, severity and frequency of nausea, and type of HSCT were the predictors of trait anxiety. The results also showed the predictor role of pain, fatigue, and type of HSCT in state anxiety. The findings revealed a correlation between anxiety and pain, fatigue, nausea, and vomiting among the HSCT patients. The results also showed fatigue and pain as the predictors of anxiety among these patients. Yet, future studies are recommended to determine the other factors contributing to anxiety amongst HSCT patients.

Health care professionals' understanding of contraindications for physical activity advice in the setting of stem cell transplantation

PURPOSE

Most patients receiving a hematopoietic stem cell transplantation (HSCT) are able to tolerate and benefit from physical activity (PA). Therefore, it is important that health care professionals (HCPs) advise patients to perform PA before, during, and after transplantation. By understanding which medical conditions and safety issues are associated with the (non-) promotion of PA, concrete actions and interventions can be planned and implemented.

METHODS

Physicians (N = 51), nurses (N = 52), and physical therapists (N = 26) participated in a nationwide cross-sectional online survey. HCPs' understanding of 15 medical conditions as contraindications for PA was assessed. Significant group differences were determined using chi-square analysis.

RESULTS

Acute infection was the only condition which was considered as contraindication by all HCPs (62.7%). Cachexia (78%), having a stoma (91%), or port (96.2%), psychological problems (88.4%), and leukopenia (83.3%) were not considered as contraindications. Six conditions were rated inconsistently between the groups, whereas physicians had the least concerns regarding PA. Physicians with an additional training in PA perceived a platelet count of ≤ 50,000/μl significantly less often as contraindication (p < 0.05).

CONCLUSION

The large number of potentially-answers especially in nursing staff and physical therapists might reflect caution or uncertainty. There is a clear need for a good multidisciplinary cooperation between all HCPs in order to support patients to confidently engage in PA. Furthermore, education possibilities and evidence-based courses to build knowledge regarding safety concerns should be the standard practice in the setting of HSCT. The investigative nature of the paper indicates that certain trends should be interrogated in a causal-longitudinal design.

Effects of a physiotherapeutic protocol in cardiorespiratory, muscle strength, aerobic capacity and quality of life after hematopoietic stem cell transplantation

OBJECTIVE

To analyze the effects of hospital cardiorespiratory physical therapy protocol on the functional capacity and quality of life of patients submitted to hematopoietic stem cell transplantation (HSCT).

METHODS

From January to December 2019, bilateral dynamometry, Manovacuometry and Ventilometry, peak expiratory flow "Peak Flow", 6-min walk test (6MWT), SF-36 Quality of Life Questionnaire and Visual Analog Scale (VAS) were applied in patients who have undergone an allogeneic or autologous hematopoietic stem cell transplantation (HSCT), pre-conditioning (initial evaluation) and pre-discharge (final evaluation). The patients were submitted to an intervention protocol, consisting of aerobic training, muscle strengthening and respiratory muscle training, between the two assessments.

RESULTS

29 patients were enrolled in the study and 24 (83%) completed all procedure. Myeloablative and reduced intensity conditioning were performed in 89.6% and 10.4%, respectively; 17 (58%) patients have undergone an autologous HSCT; 10 (35%) identical related allogeneic HSCT, and 2 (7%) haploidentical allogeneic HSCT. The median number of interventions per patient was 3 (1-9). A decreasing in the right and left dynamometry (p  ≤ 0.0001 and 0.002, respectively) and, also in the distance covered in the 6MWT (p  = 0.004), was observed after HSCT. There was no significant difference in respiratory muscle strength, quality of life and fatigue sensation.

CONCLUSION

Cardiorespiratory rehabilitation can preserve functional capacity and quality of life.

People With Hematological Malignancies Treated With Bone Marrow Transplantation Have Improved Function, Quality of Life, and Fatigue Following Exercise Intervention: A Systematic Review and Meta-Analysis

OBJECTIVE

For people with hematological malignancies treated with bone marrow transplantation (BMT), this systematic review aimed to identify, evaluate, and synthesize the evidence examining the effect of exercise training on the outcomes of exercise capacity, health-related quality of life (HRQoL), and hospital length of stay (LOS) and to identify any difference in the effect on people treated with allogeneic versus autologous transplantation.

METHODS

Five electronic databases were systematically searched from inception to December 5, 2020. Prospective studies with a comparator group, with or without randomization, were included if they investigated the effects of an exercise intervention compared with usual care or another intervention in adults who had a hematological malignancy and were undergoing BMT. Primary outcomes of interest were functional exercise capacity and HRQoL; secondary outcomes included strength, fatigue, hospital LOS, and feasibility. Only randomized controlled trials were included in the meta-analyses. Risk of bias was evaluated using the Physiotherapy Evidence Database or Newcastle-Ottawa Scale; the quality of evidence for meta-analyses was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach.

RESULTS

Twenty-four randomized controlled trials and 3 prospective nonrandomized experimental trials were included (n = 2432). There was moderate-quality evidence that exercise improves functional exercise capacity (mean difference [MD] = 29 m; 95% CI = 12.59 to 45.4), global HRQoL (MD = 3.38 points; 95% CI = 0.37 to 6.39), and fatigue (MD = 2.52 points; 95% CI = 0.42 to 4.63) and low-quality evidence for reduced hospital LOS (MD = 2.07 days; 95% CI = 0.43 to 3.72). These effects were more pronounced in recipients of allogeneic transplantation. No serious adverse events were associated directly with exercise in the included studies.

CONCLUSION

Exercise is safe and improves outcomes, including functional exercise capacity, HRQoL, and hospital LOS in adults undergoing BMT.

IMPACT

The results of this systematic review support the implementation of exercise programs in adults undergoing BMT, particularly recipients of allogeneic transplantation.

Bleeding frequency during physiotherapy in thrombocytopenic patients undergoing hematopoietic stem cell transplantation

BACKGROUND

During hematopoietic stem cell transplantation (HSCT) the patients perform activities of low and moderate intensity because have reduced hematological lineages, leaving them susceptible to hemorrhagic events. The objective of this study was to describe the frequency of bleeding events, severity, and possible association with physical exercise in thrombocytopenic patients.

METHODS

A retrospective study with seventy-seven HSCT patients hospitalised, that had a platelet count ≤ 50,000 /μL and received physical exercise during physiotherapy intervention.

RESULTS

Regarding bleeding events, only six were related to physical exercise, and bleeding events occurred more frequently at platelet levels ≤ 10,000 /μL. The most frequent bleeding event was epistaxis, considered of low severity, and with the moderate possibility of being related to physical exercise; followed by extremity hematoma, considered of medium severity and highly related to physical exercise. In this study, there was no occurrence of bleeding events considered of high severity.

CONCLUSION

Bleeding frequency in supervised physical exercise during physiotherapy in adults with thrombocytopenia undergoing HSCT is minor and relatively rare but occurs more frequently in patients with platelet count ≤10,000 /μL. These results encourage the maintenance of physical activity in this population who is at high risk of developing immobility-related complications.

Feasibility of early-commencing group-based exercise in allogeneic bone marrow transplantation: the BOOST study

Increasing evidence supports that individualised exercise is safe and beneficial for adults treated with allogeneic bone marrow transplantation (alloBMT), although this is not part of standard care and no research has investigated group-based interventions. This study aimed to determine safety, feasibility and exploratory effects of a supervised group-based inpatient and subsequent home-based exercise programme in alloBMT. This single-site prospective cohort study included consecutive adults treated with alloBMT for haematological disease. All participants received usual care in addition to the protocolised exercise programme pre-transplant until 60 days post transplant. The primary outcome was feasibility; secondary outcomes included exercise capacity, frailty, health-related quality of life and strength. Consent rate was 100% (n = 42); 83% (n = 35) completed all aspects of the intervention and outcome testing; of those, 83% (n = 29) attended ≥2 group-exercise sessions per week; no adverse events occurred. Emotional well-being significantly improved over time, which may highlight benefits of group-based intervention. Other outcomes significantly declined from pre-BMT to hospital discharge, with some improvement at 60 days post-BMT. Participants with early signs of frailty demonstrated the greatest decline in outcomes. Group-based exercise was safe and feasible; observations from this study highlight the importance of baseline identification of frailty to target intervention at those who need it most.

Muscle oxygen extraction and lung function are related to exercise tolerance after allogeneic hematopoietic stem cell transplantation

PURPOSE

This study aimed to investigate the relationship between exercise intolerance, muscle oxidative metabolism, and cardiopulmonary function following allogeneic hematopoietic stem cell transplantation (allo-HSCT) in a sterile isolation room setting.

METHODS

This was a prospective observational cohort study conducted in a single center. Fourteen patients with hematopoietic malignancies who had undergone allo-HSCT were included in this study from June 2015 to April 2020. Patients received donor HSCT after high dose-chemotherapy and total-body irradiation. Physical activity was limited during treatments. Outcome measures included body anthropometric measurements, exercise tolerance tests using the ramp protocol, pulmonary function tests, and near-infrared spectroscopy (NIRS) measurements. Data of pre- and posttransplant measurements were compared using the paired t test or nonparametric Wilcoxon U test. Associations were assessed using the Pearson or nonparametric Spearman correlations.

RESULTS

NIRS showed reduced muscle consumption and extraction of oxygen in the posttransplant period compared to the pretransplant period (ΔStO_{2 min} pre: -18.6% vs. post: -13.0%, P = 0.04; ΔHHb _max pre: 4.21μmol/l vs. post: 3.31μmol/l: P = 0.048). Exercise tolerance had reduced following allo-HSCT (Peak workload pre: 70.3 W vs. post: 58.0 W: P = 0.014). Furthermore, exercise intolerance was associated with pulmonary function, muscle oxygen consumption, and muscle oxygen extraction (all P <0.05).

CONCLUSION

This analysis revealed that exercise intolerance following allo-HSCT was associated with pulmonary dysfunction and muscle oxidative dysfunction. These findings could help identify the physical function associated with impaired tissue oxygen transport leading to exercise intolerance following allo-HSCT.

Role of Physical Activity and Cardiac Rehabilitation in Patients Undergoing Hematopoietic Stem Cell Transplantation

Hematopoietic stem cell transplantation (HSCT) is a standard treatment for several malignancies, and >50,000 HSCT are performed annually worldwide. As survival after HSCT improves, cardiovascular disease and associated risk factors have gained importance as a significant cause of morbidity and mortality in this cohort. In this article, we detail the risk factors for cardiovascular disease and their impact in patients undergoing HSCT. Additionally, we critically review the data on the impact of physical exercise in patients undergoing HSCT. Although limited by significant heterogeneity in methodologies, small sample sizes, attrition, and lack of long-term cardiovascular follow-up, most of these studies reinforce the beneficial effects of physical activity and exercise in this patient population. Cardiac rehabilitation (CR) is a structured exercise and lifestyle modification program that is typically instituted in patients who experience acute cardiovascular events. We review the data on CR in the oncologic and nononcologic populations with an aim of building a framework for use of CR in HSCT patients.

•

Patients surviving HSCT have a higher incidence of cardiovascular risk factors and cardiovascular disease than the general population.

•

Physical activity can improve cardiovascular fitness, strength, and quality of life and decrease fatigue in HSCT patients and survivors.

•

In addition to physical exercise, cardiac rehabilitation also involves dietary and smoking cessation counseling, medication management, and psychosocial support, and it may therefore offer a unique framework to mitigate cardiovascular risk in HSCT.

•

Early referral, cardiovascular risk stratification, monitoring for complications, and multimodal lifestyle interventions should form the backbone of cardiac rehabilitation in this population.

•

Outcome data on quality of life indices and survival as potential benefits of cardiac rehabilitation in HSCT are needed.

Physical Activity and Sleep Measures Using a Fitness Tracking Device during Hematopoietic Cell Transplantation: A Pilot Study

Patients undergoing hematopoietic cell transplantation (HCT) experience decline in their physical activity during their transplant admission. There is limited experience with prospective monitoring of transplant recipients. We therefore measured physical activity and sleep patterns of subjects undergoing autologous and allogeneic HCT. Eighty-three patients were consented for this study. Sixty-three patients competed the study and had their physical activity prospectively assessed using the fitness-tracking device Fitbit HR. Outcomes included adherence, physical activity, readmission, hematopoietic engraftment, and 100-day survival. Sixty percent of patients (n = 37) underwent autologous HCT, and 40% (n = 26) underwent allogenic HCT. Both groups had a comparable number of steps at admission to the hospital. The number of daily steps during the study period was lower in the allogeneic group (2159 versus 3008, P = .07), as was the minimum number of steps recorded over the transplant admission (allogeneic HCT = 395 versus autologous HCT = 848, P = .01). Patients undergoing allogeneic HCT were less active on the day before discharge (1956 steps versus 3183 steps, P = .08). In multivariate analysis, physical activity was not associated with HCT-related outcomes. Patients undergoing HCT experience significant decline in their physical activity during their transplant admission that does not recover by the time of discharge. This effect can be objectively measured using fitness tracking devices.

Should healthcare organisations offer ongoing rehabilitation services for patients undergoing haematopoietic cell transplant? A narrative review

Purpose

Hematopoietic stem cell transplant (HSCT) patients can suffer from long-term transplant-related complications that affect their quality of life and daily activities. This study, a narrative review, aims to report the impact of HCT complications, the benefits of rehabilitation intervention, the need for long-term care and highlights the research gap in clinical trials involving rehabilitation.

Design/methodology/approach

A comprehensive search strategy was performed on several databases to look for relevant articles published from 1998 to 2018. Articles published in English with the following terms were used: hematopoietic stem cell transplant, chronic graft-versus-host disease, rehabilitation, exercise, physical therapy, occupational therapy. A patient/population, intervention, comparison, and outcomes (PICO) framework was employed to ensure that the search strategies were structured and precise. Study year, design, outcome, intervention, sample demographics, setting and study results were extracted.

Findings

Of the 1,411 records identified, 51 studies underwent title/abstract screening for appropriateness, 30 were reviewed in full, and 19 studies were included in the review. The review found that, for the majority of patients who underwent HSCT and developed treatment-related complications, rehabilitation exercises had a positive impact on their overall quality of life. However, exercise prescription in this patient group has not always reflected the scientific approach; there is a lack of high-quality clinical trials in general. The review also highlights the need to educate healthcare policymakers and insurance companies responsible for rationing services to recognise the importance of offering long-term follow-up care for this patient group, including rehabilitation services.

Practical implications

A large number of HSCT patients require long-term follow-up from a multidisciplinary team, including rehabilitation specialists. It is important for healthcare policymakers and insurance companies to recognise this need and take the necessary steps to ensure that HSCT patients receive adequate long-term care. This paper also highlights the urgent need for high-quality rehabilitation trials to demonstrate the feasibility and importance of rehabilitation teams.

Originality/value

Healthcare policymakers and insurance companies need to recognise that transplant patients need ongoing physiotherapy for early identification of any functional impairments and appropriate timely intervention.

Functional Capacity Change Impacts the Quality of Life of Hospitalized Patients Undergoing Hematopoietic Stem Cell Transplantation

OBJECTIVE

The aim of the study was to compare the quality of life (QOL) of patients undergoing hematopoietic stem cell transplantation who improved their functional capacity during hospitalization (increased functional capacity group) with that of patients who maintained or decreased functional capacity during hospitalization (decreased functional capacity group).

DESIGN

This observational, longitudinal study included 27 hospitalized patients undergoing hematopoietic stem cell transplantation. Patients were divided into increased functional capacity group (16 patients) and decreased functional capacity group (11 patients). Functional capacity (6-min step test), peripheral muscle strength (sit-to-stand test and handgrip strength), and QOL (European Organization for Research and Treatment of Cancer) were assessed at admission and at hospital discharge.

RESULTS

Increased functional capacity patients had increased functional capacity and peripheral muscle strength of the lower and upper limbs at hospital discharge (P < 0.01, <0.01, and 0.02, respectively). The patients in the increased functional capacity group demonstrated an increase in global health and reduced symptoms at discharge (P = 0.02 and 0.03, respectively). No significant differences were observed between groups in the functional domain.

CONCLUSIONS

Patients undergoing hematopoietic stem cell transplantation, who have improved functional capacity at discharge, also experience an improved QOL, with no such improvement noted among patients who have stable or reduced functional capacity. We recommend that the treatment protocol for hospitalized patients undergoing hematopoietic stem cell transplantation include an exercise program aimed at improving functional capacity.

Individualized in-hospital exercise training program for people undergoing hematopoietic stem cell transplantation: a feasibility study

PURPOSE

The purpose of this study is to evaluate the feasibility of an individualized exercise program for people undergoing hematopoietic stem cell transplantation.

METHODS

This is a feasibility study of an individualized in-hospital exercise training program for people undergoing hematopoietic stem cell transplantation. Participants performed the exercise program based on daily clinical, hemodynamic and hematological assessment. The program was carried out on a daily basis for 20-40 min during their hospital admission. The primary outcome was feasibility (recruitment, adherence and attrition rates) of the exercise program. The secondary outcomes were functional capacity, peripheral muscle strength, and health-related quality of life evaluated on admission and prior to hospital discharge. The adverse events rate was recorded during the intervention.

RESULTS

Twenty-six participants (58% female), aged 40 ± 15 (mean ± SD) years were included. The exercise program feasibility was demonstrated by 100% recruitment, 86% exercise adherence and 12% attrition rates with no adverse events recorded. Significant differences were observed in functional capacity (p = 0.03), upper and lower-limb muscle strength (p = 0.01) from admission to discharge (23 ± 7 d).

CONCLUSIONS

An individualized exercise training program based on daily clinical parameters is feasible for hospitalized patients undergoing hematopoietic stem cell transplantation. This intervention warrants further investigation in a randomized controlled trial. Implications for rehabilitation The individualized in-hospital exercise training program guided by daily clinical, hemodynamic and hematologic parameters is feasible, safe and with good adherence in people undergoing hematopoietic stem cell transplantation. People undergoing hematopoietic stem cell transplantation may improve functional capacity and upper and lower limb muscle strength following in-hospital exercise training program. The individualized in-hospital exercise training program could tentatively be introduced as part of the rehabilitation process in people undergoing hematopoietic stem cell transplantation.

The benefit of exercise in patients who undergo allogeneic hematopoietic stem cell transplantation

Allogeneic hematopoietic stem-cell transplantation (allo-HSCT) is increasingly used in the treatment of hematologic cancers such as leukemias, lymphomas, and myeloma, and for other hematologic disorders such as primary immunodeficiency, aplastic anemia, and myelodysplasia. Allo-HSCT entails a conditioning regimen of frequent high-dose chemotherapy in combination with total body irradiation, followed by infusion of donor-harvested bone marrow or peripheral blood stem cells. As an aggressive and demanding medical therapy that profoundly impacts patient quality of life (QOL), allo-HSCT is associated with numerous treatment-related physical, psychological, and psychosocial side effects. The procedure can result in decreased respiratory and balance function, skeletal muscle strength, and exercise capacity. Thus, as physical exercise has been shown to positively effect physical and psychosocial function and QOL in allo-HSCT patients, it is a recommended intervention for improving essential functions and offsetting lost exercise capacity after the procedure. Furthermore, recent evidence has shown that physical exercise can influence survival rate and mortality in allo-HSCT patients. This review provides an overview of the current research on the effectiveness of physical exercise for allo-HSCT patients.

Low-intensity exercise therapy with high frequency improves physical function and mental and physical symptoms in patients with haematological malignancies undergoing chemotherapy

This study aimed to investigate the effects of low-intensity exercise therapy (LIET) on the physical and mental symptoms and functions in patients with haematological malignancies undergoing chemotherapy. Forty-four patients hospitalised for chemotherapy performed LIET. The exercise intensity of LIET was defined as achieving <40% of the predicted maximum heart rate calculated using the Karvonen formula. LIET consisted of aerobic and resistance training, which was carried out on weekdays. The intervention was omitted in the case of poor general health status and strong patient refusal. Muscular and physical function, activities of daily living (ADLs), psychological distress and quality of life (QOL) were evaluated upon initiation of rehabilitation and at discharge. Participants were divided into high- and low-frequency groups according to their LIET frequency. Two-way repeated-measures analysis of variance was used for statistical analysis. In the high-frequency group, muscle function was maintained, while physical function, ADLs, psychological distress and QOL were significantly improved. However, in the low-frequency group, muscle function of the lower limb was significantly reduced and no other improvement was observed. Low-intensity exercise therapy could be a potential treatment strategy for patients with haematological malignancies undergoing chemotherapy who are unable to perform mid- or high-intensity exercise.

Changes in Borg scale for resistance training and test of exercise tolerance in patients undergoing allogeneic hematopoietic stem cell transplantation

PURPOSE

We aimed to investigate the relationship between Borg scale and intensity of resistance training in patients who had undergone allogeneic hematopoietic stem cell transplantation (allo-HSCT). Furthermore, the relationship between Borg scale, heart rate (HR), and intensity of exercise tolerance test was also studied.

METHODS

The study included 28 patients (19 men and 9 women) who had undergone allo-HSCT between June 2015 and February 2017. Their knee extension strengths and exercise tolerances were evaluated. Patients were asked to grade between 0 and 10 on Borg scale based on the level of difficulty experienced during exercising, after 10 repetitions in randomized 20, 40, and 60% resistance training for knee extension. Additionally, we evaluated Borg scale, HR, and load intensity during exercise tolerance test, every minute of the exercise for 2 weeks before and 3 weeks after HSCT.

RESULTS

Knee extension strength and exercise tolerance were significantly decreased 3 weeks after HSCT from those before HSCT (p < 0.01). Additionally, rise in Borg scale with increase in load intensity during knee extension resistance training, both before and after HSCT (p < 0.01), was noted. Furthermore, Borg scale was found to be associated with HR and load intensity during exercise tolerance test in patients both before and after HSCT (p < 0.01).

CONCLUSIONS

A correlation was found between Borg scale with intensity of resistance training and exercise tolerance in patients who had undergone allo-HSCT. Therefore, Borg scale could be useful to determine the intensity of physical exercise in patients who have undergone allo-HSCT.

Bleeding frequency and characteristics among hematologic malignancy inpatient rehabilitation patients with severe thrombocytopenia

OBJECTIVE

To identify the frequency and characteristics of bleeding complications during acute inpatient rehabilitation of hematologic malignancy patients with severe thrombocytopenia.

DESIGN

Retrospective descriptive analysis.

SETTING

Comprehensive cancer center acute inpatient rehabilitation unit.

PARTICIPANTS

Consecutive hematologic malignancy patients with a platelet count of less than or equal to 20,000/microliter (μL) on the day of acute inpatient rehabilitation admission from 1/1/2005 through 8/31/2016.

INTERVENTIONS

Medical records were retrospectively analyzed for demographic, laboratory, and medical data. Patients were rehabilitated using the institutional exercise guidelines for thrombocytopenic patients.

MAIN OUTCOME MEASURES

Bleeding events noted in the medical record.

RESULTS

Out of 135 acute inpatient rehabilitation admissions, 133 unique patients were analyzed with a total of 851 inpatient rehabilitation days. The mean platelet count was 14,000/μL on the day of admission and 22,000/μL over the course of the rehabilitation admission. There were 252 days of inpatient rehabilitation where patients had less than 10,000/μL platelets. A total of 97 bleeding events were documented in 77/135 (57%) admissions. Of the 97 bleeding events, 72 (74%), 14 (14%), and 11 (11%) were considered to be of low, medium, and high severity, respectively. There were 4/97 (4%) bleeding events that were highly likely attributable to physical activity but only 1/4 was considered high severity. Bleeding rates were .09, .08, .17, and .37 for > 20,000, 15-20,000, 10-15,000, and < 10,000/μL mean platelet counts respectively (p = .003). Forty-four percent of patients were transferred back to the primary acute care service with infection being the most common reason for transfer.

CONCLUSIONS

This study is the first to examine exercise-related bleeding complications during acute inpatient rehabilitation in severely thrombocytopenic hematologic cancer patients. Bleeding rates increased with lower platelet counts. However, using the exercise guidelines for severely thrombocytopenic patients, the risk of severe exercise-related bleeding events was low.

Impaired skeletal muscle oxygenation following allogeneic hematopoietic stem cell transplantation is associated with exercise capacity

INTRODUCTION

Impaired skeletal muscle oxygenation potentially contributes to reduced exercise capacity in allogeneic hematopoietic stem cell transplantation (allo-HSCT) patients during early recovery and may explain altered hemoglobin responses to exercise following allo-HSCT. We investigated whether skeletal muscle oxygenation parameters and hemoglobin parameters in the tibialis anterior decreased following allo-HSCT, and whether these results were associated with declines in exercise capacity.

METHODS

We used near-infrared spectroscopy during and following a repeated isometric contraction task at 50% of maximal voluntary contraction in 18 patients before and after allo-HSCT.

RESULTS

The rate of decrease in the muscle oxy-hemoglobin saturation (SmO₂; an index of skeletal muscle oxygenation) was significantly lower after allo-HSCT (P < 0.01). In contrast, total hemoglobin (an index of hemoglobin) was not different after allo-HSCT. Furthermore, SmO₂ during and following exercise was associated with exercise capacity (r = 0.648; P = 0.004 vs. r = 0.632; P = 0.005).

CONCLUSION

The results of this study reveal that although the peripheral hemoglobin response was not altered by allo-HSCT, skeletal muscle oxygenation was decreased following allo-HSCT. Furthermore, the decrease in skeletal muscle oxygenation was associated with a reduction in exercise capacity.

Effects of nonpharmacological interventions on reducing fatigue after hematopoietic stem cell transplantation

Fatigue is one of the main complaints of patients undergoing allogeneic and autologous hematopoietic stem cell transplantation (HSCT). Since nonpharmacological interventions are cost-effective and causes fewer complications, this study aimed to review the studies performed on the effects of nonpharmacological interventions on fatigue in patients undergoing HSCT during September 2016. MEDLINE, CINAHL, Scientific Information Database, IranMedex, PubMed, ScienceDirect, Scopus, Magiran, and IRANDOC databases were searched using Persian and English keywords. A total of 1217 articles were retrieved, 21 of which were used in this study. Exercise is known as an effective intervention in alleviating physical and mental problems of patients undergoing stem cell transplant. This review-based study showed that nonpharmacological methods such as exercise might be effective in decreasing fatigue in patients undergoing stem cell transplant. There is a multitude of studies on some of the complementary and alternative therapy methods, such as music therapy, yoga, relaxation, and therapeutic massage. These studies demonstrated the positive effects of the aforementioned therapies on reduction of fatigue in patients undergoing stem cell transplantation. All the investigated methods in this study were nonaggressive, safe, and cost-effective and could be used along with common treatments or even as an alternative for pharmacological treatments for the reduction, or elimination of fatigue in patients undergoing stem cell transplantation. Given the advantages of complementary and alternative medicine, conducting further studies on this issue is recommended to reduce fatigue in patients after stem cell transplantation.

Balance function in patients who had undergone allogeneic hematopoietic stem cell transplantation

A previous study reported a 45% incidence of falling among allogeneic haematopoietic stem cell transplantation (allo-HSCT) patients during hospitalisation. We investigated balance and physical function in allo-HSCT patients. Thirty patients (18 men and 12 women) who underwent allo-HSCT between February 2013 and September 2014 were included in this study. Patients were evaluated for up to 3 weeks before and 7 weeks after transplantation. Balance was evaluated using the Timed Up and Go test (TUG) and length of centre of pressure (CoP). Physical function was assessed using hand-grip strength, knee-extensor strength tests, and the 6 min walk test (6MWT). TUG and length of CoP were significantly increased following HSCT (P<0.01). Hand-grip strength, knee-extensor strength, and the 6MWT score decreased significantly after allo-HSCT (P<0.01). TUG and length of CoP were negatively correlated with hand grip and knee-extensor strength (P≤0.05). The allo-HSCT patients in this study had worsened dynamic and static movements of the CoP after transplantation as well as decline of physical function. Rehabilitation staff, nurses, and physicians should recognize the decreased balance function of patients who have undergone allo-HSCT.

Rehabilitation referrals and outcomes in the early period after hematopoietic cell transplantation

In a cohort of inpatient hematopoietic cell transplantation (HCT) recipients, we assessed patterns of referral to rehabilitation treatment, functional performance and short-term outcomes in patients who received post-transplant rehabilitation in comparison with those who did not. Among 201 first-time HCT recipients, 53 (26%) were referred to an inpatient rehabilitation provider, had an assessment of functional performance using the Functional Independence Measure scale and underwent rehabilitation treatments to address functional needs. Patients who received rehabilitation therapy were more likely to be females (P=0.02), older than 60 years of age (P=0.0146), employed (P=0.01), have hypertension (P=0.02), peripheral vascular disease (P=0.01) and pre-transplant Karnofsky Performance Score (KPS) <90 (P=0.02). Mean functional performance scores for transfers and ambulation increased significantly in the group with rehabilitation interventions (P=0.0022 and P<0.0001, respectively). There was no difference between the groups that did and did not receive rehabilitation treatments in 30-day re-admission rates. Patients who are 60 years of age or older, with pre-transplant KPS<90, and pre-transplant hypertension were more likely to be referred for rehabilitation treatments in the early period after HCT. Future studies should be designed to determine the optimal timing and cost effectiveness of functional assessment and rehabilitation treatments in this high-risk population.

Early-phase differences in health-related quality of life, psychological status, and physical function between human leucocyte antigen-haploidentical and other allogeneic haematopoietic stem cell transplantation recipients

PURPOSE

This study investigated the differences between allogeneic haematopoietic stem cell transplantation (allo-HSCT) patients receiving HSC from human leucocyte antigen (HLA)-haploidentical donors (HID) and other donors that included HLA-matched sibling, matched unrelated, and unrelated umbilical cord blood donors in the 6 weeks after HSCT with respect to quality of life (QOL), psychological status, and physical function.

METHODS

The study included 126 patients (HID group, n = 100; other donor group, n = 26) who underwent allo-HSCT between July 2007 and December 2012. Patients were evaluated for health-related QOL using the Medical Outcome Study 36-item Short Form Health Survey. Psychological status was measured by Hospital Anxiety and Depression Scale. Physical function was assessed using tests for handgrip strength, knee extensor strength, and the 6-min walk test.

RESULTS

After HSCT, the HID group showed significantly greater improvements in the general health subscale and Mental Component Summary (MCS) of QOL than the other donor group (P < 0.01). Multivariate analysis confirmed that complete remission and age were associated with changes in the general health subscale before and after HSCT (P < 0.05). With regard to physical function, the HID group showed significantly more decline than the other donor group with respect to handgrip strength and knee extensor muscle strength after HSCT (P < 0.05). Total corticosteroid dose was associated with decreased handgrip strength before and after HSCT (P < 0.05).

CONCLUSIONS

The donor type affects QOL, psychological status, and physical function in allo-HSCT recipients; these findings may provide insights for customised rehabilitation strategies for HSCT recipients.
