ABSTRACT
BACKGROUND: We developed an Internet-based physical activity (PA) support program (IPAS), which is embedded in a patient portal. We evaluated the effectiveness and costs of IPAS alone (online only) or IPAS combined with physiotherapist telephone counselling (blended care), compared to a control group. METHODS: Breast or prostate cancer survivors, 3-36 months after completing primary treatment, were randomized to 6-months access to online only, blended care, or a control group. At baseline and 6-month post-baseline, minutes of moderate-to-vigorous PA (MVPA) were measured by accelerometers. Secondary outcomes were self-reported PA, fatigue, mood, health-related quality of life, attitude toward PA, and costs. (Generalized) linear models were used to compare the outcomes between groups. RESULTS: We recruited 137 survivors (participation rate 11%). We did not observe any significant between-group differences in MVPA or secondary outcomes. Adherence was rather low and satisfaction scores were low to moderate, with better scores for blended care. Costs for both interventions were low. CONCLUSIONS: Recruitment to the study was challenging and the interventions were less efficacious than anticipated, which led to lessons learned for future trials. Suggestions for future research are as follows: improved accessibility of the support program, increased frequency of support, and use of activity trackers.
ABSTRACT
PURPOSE: To evaluate the feasibility and outcomes of a tailored, goal-directed, and exercise-based physical therapy program for patients with metastatic breast cancer (MBC). METHODS: This was an observational, uncontrolled feasibility study. The physical therapy intervention was highly tailored to the individual patient's goals, abilities, and preferences and could include functional, strength, aerobic, and relaxation exercises. Feasibility outcomes were participation rate (expected: 25%), safety, and adherence (percentage of attended sessions relative to scheduled sessions). Additional outcomes were goal attainment, self-reported physical functioning, fatigue, health-related quality of life, and patient and physical therapist satisfaction with the program. RESULTS: Fifty-five patients (estimated participation rate: 34%) were enrolled. Three patients did not start the intervention due to early disease progression. An additional 22 patients discontinued the program prematurely, mainly due to disease progression. Median intervention adherence was 90% and no major intervention-related adverse events occurred. A goal attainment score was available for 42 patients (of whom 29 had completed the program and 13 had prematurely dropped out). Twenty-two (52%) of these patients achieved their main goal fully or largely and an additional 15 patients (36%) partially. Eighty-five percent would "definitely recommend" the program to other patients with MBC. We observed a modest improvement in patient satisfaction with physical activities (Cohen's dz 0.33). CONCLUSION: The tailored intervention program was feasible in terms of uptake, safety, and outcomes and was highly valued by patients and physical therapists. However, disease progression interfered with the program, leading to substantial dropout. TRIAL REGISTRATION: NTR register: NTR6475.

PURPOSE: In this study we aimed (1) to identify the most prevalent physical symptoms and functional limitations that limit physical activity of patients with palliative treatment for metastatic breast cancer (MBC) and (2) to identify their preferences for exercise-based physical therapy programs, as a first step towards the development of physical therapist (PT)-guided exercise programs for patients with MBC. METHODS: We performed a mixed-method study that comprised a cross-sectional survey and two focus group sessions among patients with MBC. Survey results were analyzed using descriptive statistics. The focus groups were audio-taped, transcribed verbatim, and analyzed independently by two researchers, using directed content analysis. RESULTS: A total of 114 women (response rate 61%) completed the survey (mean age 63.5, SD 10.2). Eighty-six percent of the women reported at least some level of physical problems limiting their ability to be physically active, of whom 46% reported substantial problems. The most prevalent problems were fatigue, painful joints, painful muscles, and shortness of breath. Uptake of exercise appeared to be limited. Exercise preferences varied strongly. Fifty-three percent indicated a preference for some form of PT-supervision, and 34% for a prolonged period of time (> 8 weeks). Focus group results clarified that patients' preferences for supervision, by PTs with special qualifications in oncology, were related to feelings of insecurity about their ability to self-manage physical functioning. CONCLUSIONS: Patients with MBC experience a broad range of physical health problems that limit their ability to be physically active. While preferences vary strongly, patients with MBC would value the availability of high quality, PT-guided, tailored exercise programs.

BACKGROUND: Higher levels of physical activity (PA) after treatment are associated with beneficial effects on physical and psychosocial functioning of cancer survivors. However, survivors often do not meet the recommended levels of PA. In order to promote PA, we developed a closed internet-based program. The aim of the study is to evaluate the (cost-)effectiveness of an internet-based PA-promotion program, alone or combined with physiotherapy counselling, compared to usual care, on PA-levels of breast or prostate cancer survivors. In this multicenter randomised controlled trial (RCT), breast or prostate cancer survivors who completed their primary treatment 3-12 months earlier, will be randomised to either 6-months access to a fully-automated internet-based intervention alone, an internet-based intervention plus remote support by a physiotherapist, or a control group. The intervention is based on the Transtheoretical Model and includes personalized feedback, information, video's and assignments. Additionally, in a second arm, physiotherapy counselling is provided through monthly scheduled and on-demand telephone calls. The control group will receive usual care and a leaflet with PA guidelines. METHODS: At baseline, 6 and 12 months, the primary outcome (PA) will be measured during 7 consecutive days by accelerometers. Secondary outcomes are self-reported PA, fatigue, mood, health-related quality of life, and costs. The group differences for primary and secondary outcomes will be analyzed using linear mixed models. DISCUSSION: If proven to be (cost)effective, this internet-based intervention, either alone or in combination with telephone support, will be a welcome addition to previous RCT's. TRIAL REGISTRATION: Netherlands trial register (NTR6911), Date of trial registration: December 21, 2017.

PURPOSE: The aim of this study is to evaluate the feasibility of a telehealthcare application for operable lung cancer (OLC) patients, consisting of ambulant symptom and physical activity monitoring (S&PAM) and a web-accessible home-based exercise program (WEP), and identify possible barriers for successful adoption and implementation. METHODS: A two-stage mixed methods design was used, in which 22 OLC patients and their treating healthcare professionals (HCPs) participated from pre-surgery to three (stage 1; n = 10) or six (stage 2; n = 12) months post-surgery. Actual use and acceptability (usability, usefulness, and satisfaction) were evaluated. RESULTS: Seventeen OLC patients (age (SD): 59 (8) years; 8 female) actively used the modules. S&PAM use varied from 1 to 11 monitoring days prior to outpatient consultations. Patients used WEP most frequently during the first 5 weeks, with an average of four logins a week. Fifty-eight percent used WEP beyond 7 weeks. No adverse situations occurred, and patients felt confident using the applications. Perceived added value included active lifestyle promotion, decreased anxiety, and accessibility to specialized HCPs. Physiotherapists used WEP as intended. Contrarily, physicians scarcely used information from S&PAM. To promote future adoption, strategies should focus on high-level patient tailoring of the technology, and formalization of including the applications in the clinical workflow. CONCLUSIONS: Ambulant monitoring and web-accessible home exercise is clinically feasible for OLC patients. However, low level of adoption by referring physicians may hamper successful implementation. IMPLICATIONS FOR CANCER SURVIVORS: Patients perceived both ambulant monitoring and web-accessible exercise as an added value to regular care and feasible to use in the period before and after lung resection.

Increase of factor VIII activity (FVIII) after physical exercise has been reported in healthy subjects and small-scale studies in patients with coagulopathies. The aim was to study whether moderate and mild haemophilia A patients are able to increase their endogenous FVIII activity levels by physical activity. We studied changes in FVIII activity levels after high-intensity exercise in 15 haemophilia A patients, 20-39 years, eight with moderate, seven with mild haemophilia. Patients cycled until volitional exhaustion, blood samples were drawn before and 10 min after the exercise test. FVIII activity increased 2.5 times (range 1.8-7.0 times), for both severities. Absolute increases were markedly different: median 7 IU dL(-1) (range 3-9 IU dL(-1) ) in patients with moderate, compared to 15 IU dL(-1) (range 6-62 IU dL(-1) ) in mild haemophilia patients. VWF and VWFpp increased independently of severity; median 50% (range 8-123%) and median 165% (range 48-350%), respectively, reflecting acute release of VWF. These observations may be used to promote high-intensity activities before participating in sports for moderate and mild haemophilia A patients, to reduce bleeding risk. Further studies are warranted to fully appreciate the clinical significance of exercise on different levels of intensity in patients with mild and moderate haemophilia A.

For patients with haemophilia, a physically active lifestyle is important to maintain musculoskeletal health and to prevent chronic diseases, such as cardiovascular disease. Therefore, we studied physical activity levels, in Dutch children and adolescents with haemophilia as well as its association with aerobic fitness and joint health. Forty-seven boys with haemophilia (aged 8-18) participated. Physical activity was measured using the Modifiable Activity Questionnaire (MAQ) and was compared with the general population. Aerobic fitness was determined using peak oxygen uptake (VO(2peak)). Joint health was measured using the Haemophilia Joint Health Score (HJHS). Associations between physical activity, joint health and aerobic fitness were evaluated by correlation analysis. Subjects were 12.5 (SD 2.9) years old, had a Body Mass Index (BMI) of 19.5 (SD 3.1; z-score 0.5) and a median HJHS score of 0 (range 0-6). Cycling, physical education and swimming were most frequently reported (86%, 69% and 50% respectively). Children with severe haemophilia participated significantly less in competitive soccer and more in swimming than children with non-severe haemophilia. Physical activity levels were similar across haemophilia severities and comparable to the general population. VO(2peak) kg⻹ was slightly lower than healthy boys (42.9 ± 8.6 vs. 46.9 ± 1.9 mL kg⻹ min⻹; P = 0.03). Joint health, aerobic fitness and physical activity showed no correlation. Dutch children with haemophilia engaged in a wide range of activities of different intensities and showed comparable levels of physical activity to the general population. Aerobic fitness was well preserved and showed no associations with physical activity levels or joint health.

The purposes of this study were all to determine if DeltaVO2/DeltaWR is dependent on age, body mass, height and fitness and if DeltaVO2/DeltaWR could discriminate between healthy children and children with a chronic disease that limits O2 delivery or utilization. Four groups were included: muscle disease (Juvenile Dermatomyositis; JDM; n=12), lung disease (Cystic Fibrosis; CF; n=13), Congenital Heart Disease (CHD; (n=13), and healthy children (n=44). All children performed a cardiopulmonary exercise test on a cycle ergometer with respiratory gas analysis. The DeltaVO2/DeltaWR was determined by linear regression using data from unloaded cycling to peak exercise. No associations were found between the DeltaVO2/DeltaWR and age, body mass and height in healthy children. DeltaVO2/DeltaWR was significantly correlated with VO2peak/kg (r=0.44; p<0.01). Children with JDM had lower DeltaVO2/DeltaWR values than healthy children (p=0.02), and DeltaVO2/DeltaWR tended to be lower in CHD and higher in CF (p=0.09 and p=0.08, respectively). DeltaVO2/DeltaWR may be more sensitive for conditions that are characterized by local hypo perfusion (as in JDM), than for conditions that are characterized by impaired oxygen delivery (i. e. CF or CHD).

SUMMARY: Worldwide, children with haemophilia suffer from limitations in performing activities of daily living. To measure such limitations in adults a disease-specific instrument, the Haemophilia Activities List (HAL), was created in 2004. The aim of this study was to adapt the HAL for children with haemophilia and to assess its psychometric properties. The structure and the main content were derived from the HAL. Additionally, items of the Childhood Health Assessment Questionnaire and the Activity Scale for Kids were considered for inclusion. This version was evaluated by health professionals (n = 6), patients (n = 4), and parents (n = 3). A pilot test in a sample of 32 Dutch children was performed to assess score distribution, construct validity (Spearman's rho) and reproducibility. Administration of the pedhal was feasible for children from the age of 4 years onwards. The pedhal scores of the Dutch children were in the high end of the scale, reflecting a good functional status. Most subscales showed moderate associations with the joint examination (rho = 0.42-0.63) and moderate-to-good associations with the physical function subscale of the CHQ-50 (rho = 0.48-0.74). No significant associations were found for the pedhal and the subscales mental health and behaviour, except for the subscales leisure and sport and mental health (rho = 0.47). Test-retest agreement was good. The pedhal is a promising tool, but further testing in populations with a higher level of disability is warranted to study the full range of its psychometric properties.

Cardiopulmonary exercise testing (CPET) in paediatric cardiology differs in many aspects from the tests as performed in adult cardiology. Children's cardiovascular responses during exercise testing present different characteristics, particularly oxygen uptake, heart rate and blood pressure response, which are essential in interpreting haemodynamic data. Diseases that are associated with myocardial ischaemia are very rare in children. The main indications for CPET in children are evaluation of exercise capacity and the identification of exercise-induced arrhythmias. In this article we will review exercise equipment and test protocols for CPET in children with congenital heart disease. (Neth Heart J 2009;17:339-44.).
ABSTRACT
Cardiopulmonary exercise testing (CPET) in paediatric cardiology differs in many aspects from the tests performed in adult cardiology. Children's cardiovascular responses during exercise testing present different characteristics, particularly oxygen uptake, heart rate and blood pressure response, which are essential in interpreting haemodynamic data. Diseases that are associated with myocardial ischaemia are rare in children. The main indications for CPET in children are evaluation of exercise capacity and the identification of exercise-induced arrhythmias. In this article we will review the main indications for CPET in children with congenital heart disease, the contraindications for exercise testing and the indications for terminating an exercise test. Moreover, we will address the interpretation of gas exchange data from CPET in children with congenital heart disease. (Neth Heart J 2009;17:385-92.).
