Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Cancer is a serious disease that commonly causes significant psychological distress. The internet-based intervention (iCAN-DO), utilizing a stepped care approach for the treatment of anxiety and depression in individuals with cancer, has been shown to have favorable results for symptoms of depression at the primary endpoint, 10 months after randomization compared to standard care (SC). The aim of the present study was to evaluate the long-term effects of the intervention 18 and 24 months after randomization.METHODS: Patients with breast, colorectal, or prostate cancer and a score > 7 on either of the Hospital Anxiety and Depression Scale (HADS) subscales (n = 245) were recruited to the study in conjunction with a regular hospital visit. They were randomized to access to the stepwise iCAN-DO intervention for 24 months or to SC. Step 1 of the intervention comprised psycho-educative online material. In Step 2, internet-based cognitive-behavioral therapy with individual online support from a therapist was added. Step 2 was offered to those who reported persistent anxiety or depression symptoms (>7 on HADS), also at 1, 4, and/or 7 months after randomization. Missing data were imputed using the last rank carried forward method and used for the main analyses according to the intention-to-treat approach. Effects sizes (Cohen's d), and minimally clinically important difference (MCID) were calculated. Linear mixed models were used to analyze intervention effects over time.RESULTS: Symptoms of depression decreased significantly (p < 0.05) in the iCAN-DO group compared with the SC group from baseline to 18 months (d = 0.29), but not to 24 months (d = 0.27). Even though the average iCAN-DO group participant surpassed a MCID in symptoms of anxiety (>2 p) at both long-term follow-ups, the differences did not reach statistical significance, either at 18 months (p = 0.10) or 24 months (p = 0.09). Positive effects of iCAN-DO compared with the SC were also shown for some secondary HRQoL-outcomes; social functioning at 18 months (p = 0.02) and 24 months (p = 0.001), and sleep problems at 24 months (p = 0.01).CONCLUSION: A stepped-care internet-based intervention that has previously shown positive results for symptoms of depression at 10 months did show similar positive long-term effects also at 18 months. For symptoms of anxiety, no effect could be shown. The internet may provide an effective format for interventions to reduce symptoms of depression after cancer at patients' own choice of time, regardless of distance to a psycho-oncology clinic.

Induction of Human Lung Mast Cell Apoptosis by Granule Permeabilization : A Novel Approach for Targeting Mast Cells
- 2017

Tidskriftsartikel (refereegranskat)abstract
- Mast cells are implicated as detrimental players in inflammatory lung diseases, particularly asthma. Mast cells respond to activating stimuli by releasing a wide panel of pro-inflammatory compounds that can contribute profoundly to the pathology, and there is currently an unmet need for strategies that efficiently ameliorate harmful effects of mast cells under such conditions. Here, we sought to evaluate a novel concept for targeting human lung mast cells, by assessing the possibility of selectively depleting the lung mast cells by induction of apoptosis. For this purpose, we used lysosomotropic agents, i.e., compounds that are known to permeabilize the secretory granules of mast cells, thereby releasing the contents of the granules into the cytosol. Either intact human lung tissue, purified human lung mast cells or mixed populations of human lung cells were incubated with the lysosomotropic agents mefloquine or siramesine, followed by measurement of apoptosis, reactive oxygen species (ROS) production, and release of cytokines. We show that human lung mast cells were highly susceptible to apoptosis induced by this strategy, whereas other cell populations of the lung were largely refractory. Moreover, we demonstrate that apoptosis induced by this mode is dependent on the production of ROS and that the treatment of lung tissue with lysosomotropic agents causes a decrease in the release of pathogenic cytokines. We conclude that selective apoptosis of human lung mast cells can be accomplished by administration of lysosomotropic agents, thus introducing the possibility of using such drugs as novel therapeutics in the treatment of inflammatory lung disorders such as asthma.

Tidskriftsartikel (refereegranskat)abstract
- Background: The functional impact of breathlessness is assessed using the modified Medical Research Council (mMRC) scale for chronic respiratory disease and with the New York Heart Association Functional Classification (NYHA) scale for heart failure. We evaluated agreement between the scales and their concurrent validity with other clinically relevant patient-reported outcomes in cardiorespiratory disease.Methods: Outpatients with stable chronic respiratory disease or heart failure were recruited. Agreement between the mMRC and NYHA scales was analysed using Cramér's V and Kendall's tau B tests. Concurrent validity was evaluated using correlations with clinically relevant measures of breathlessness, anxiety, depression, and health-related quality of life. Analyses were conducted for all participants and separately in chronic obstructive pulmonary disease (COPD) and heart failure.Results: In a total of 182 participants with cardiorespiratory disease, the agreement between the mMRC and NYHA scales was moderate (Cramér's V: 0.46; Kendall's tau B: 0.57) with similar results for COPD (Cramér's V: 0.46; Kendall's tau B: 0.66) and heart failure (Cramér's V: 0.46; Kendall's tau B: 0.67). In the total population, the scales correlated in similar ways to other patient-reported outcomes.Conclusion: In outpatients with cardiorespiratory disease, the mMRC and NYHA scales show moderate to strong correlations and similar associations with other patient-reported outcomes. This supports that the scales are comparable when assessing the impact of breathlessness on function and patient-reported outcomes.

- BACKGROUND: Heart rate variability (HRV) has been found reduced in patients with schizophrenia and depression. However, there is a lack of knowledge on how demographic, lifestyle, and pharmacological factors contribute to the reduction in HRV in these patients.METHODS: We recruited 37 patients with schizophrenia, 43 patients with unipolar depression, and 64 healthy controls. A combined chest-worn HRV and accelerometer device was used in an ambulatory measurement. Age, sex, anticholinergic burden of medication, nicotine use, body mass index, and ongoing physical activity were assessed in multiple regression models regarding their influence on HRV, measured as the standard deviation of all the RR intervals (SDNN).RESULTS: In the fully adjusted model, schizophrenia (β = -0.23, P = 0.019), depression (β = -0.18, P = 0.028), age (β = -0.34, P < 0.000), ongoing physical activity (β = -0.23, P = 0.001), and anticholinergic burden (β = -0.19, P = 0.025) influenced SDNN negatively. Sex, nicotine use, and BMI had negligible effects on SDNN.CONCLUSIONS: We show for the first time that a quantified score of anticholinergic burden of medication has a negative relationship to HRV in patients with schizophrenia or depression, but that the diagnoses themselves still exhibit an effect on HRV.

Tidskriftsartikel (refereegranskat)abstract
- Background: Cancer-related fatigue is a common problem in persons with cancer, influencing health-related quality of life and causing a considerable challenge to society. Current evidence supports the beneficial effects of physical exercise in reducing fatigue, but the results across studies are not consistent, especially in terms of exercise intensity. It is also unclear whether use of behaviour change techniques can further increase exercise adherence and maintain physical activity behaviour. This study will investigate whether exercise intensity affects fatigue and health related quality of life in persons undergoing adjuvant cancer treatment. In addition, to examine effects of exercise intensity on mood disturbance, adherence to oncological treatment, adverse effects from treatment, activities of daily living after treatment completion and return to work, and behaviour change techniques effect on exercise adherence. We will also investigate whether exercise intensity influences inflammatory markers and cytokines, and whether gene expressions following training serve as mediators for the effects of exercise on fatigue and health related quality of life. Methods/design: Six hundred newly diagnosed persons with breast, colorectal or prostate cancer undergoing adjuvant therapy will be randomized in a 2 × 2 factorial design to following conditions; A) individually tailored low-to-moderate intensity exercise with or without behaviour change techniques or B) individually tailored high intensity exercise with or without behaviour change techniques. The training consists of both resistance and endurance exercise sessions under the guidance of trained coaches. The primary outcomes, fatigue and health related quality of life, are measured by self-reports. Secondary outcomes include fitness, mood disturbance, adherence to the cancer treatment, adverse effects, return to activities of daily living after completed treatment, return to work as well as inflammatory markers, cytokines and gene expression. Discussion: The study will contribute to our understanding of the value of exercise and exercise intensity in reducing fatigue and improving health related quality of life and, potentially, clinical outcomes. The value of behaviour change techniques in terms of adherence to and maintenance of physical exercise behaviour in persons with cancer will be evaluated. Trial registration:NCT02473003 , October, 2014.

- Exercise during cancer treatment improves cancer-related fatigue (CRF), but the importance of exercise intensity for CRF is unclear. We compared the effects of high- vs low-to-moderate-intensity exercise with or without additional behavior change support (BCS) on CRF in patients undergoing (neo-)adjuvant cancer treatment. This was a multicenter, 2x2 factorial design randomized controlled trial (Clinical Trials NCT02473003) in Sweden. Participants recently diagnosed with breast (n = 457), prostate (n = 97) or colorectal (n = 23) cancer undergoing (neo-)adjuvant treatment were randomized to high intensity (n = 144), low-to-moderate intensity (n = 144), high intensity with BCS (n = 144) or low-to-moderate intensity with BCS (n = 145). The 6-month exercise intervention included supervised resistance training and home-based endurance training. CRF was assessed by Multidimensional Fatigue Inventory (MFI, five subscales score range 4-20), and Functional Assessment of Chronic Illness Therapy-Fatigue scale (FACIT-F, score range 0-52). Multiple linear regression for main factorial effects was performed according to intention-to-treat, with post-intervention CRF as primary endpoint. Overall, 577 participants (mean age 58.7 years) were randomized. Participants randomized to high- vs low-to-moderate-intensity exercise had lower physical fatigue (MFI Physical Fatigue subscale; mean difference −1.05 [95% CI: −1.85, −0.25]), but the difference was not clinically important (ie <2). We found no differences in other CRF dimensions and no effect of additional BCS. There were few minor adverse events. For CRF, patients undergoing (neo-)adjuvant treatment for breast, prostate or colorectal cancer can safely exercise at high- or low-to-moderate intensity, according to their own preferences. Additional BCS does not provide extra benefit for CRF in supervised, well-controlled exercise interventions.

- Context: Breathlessness is a cardinal symptom in cardiorespiratory disease and consists of multiple dimensions that can be measured using the instruments Dyspnea-12 (D12) and the Multidimensional Dyspnea Profile (MDP). Objectives: The objective of the study is to determine the minimal clinically important differences (MCIDs) of all D12 and MDP summary and subdomain scores as well as the instruments' feasibility in patients with cardiorespiratory disease. Methods: Prospective multicenter cohort study of outpatients with diagnosed cardiorespiratory disease and breathlessness in daily life. D12 and MDP were assessed at baseline, after 30-90 minutes and two weeks. MCIDs were calculated using anchor-based and distributional methods for summary and subdomain scores. Feasibility was assessed as rate of missing data, help required, self-reported difficulty, and completion time. Results: A total 182 outpatients (53.3% women) were included; main diagnoses were chronic obstructive pulmonary disease (COPD; 25%), asthma (21%), heart failure (19%), and idiopathic pulmonary fibrosis (19%). Anchor-based MCIDs were for D12 total score 2.83 (95% CI 1.99-3.66); D12 physical 1.81 (1.29-2.34); D12 affective 1.07 (0.64-1.49); MDP A1 unpleasantness 0.82 (0.56-1.08); MDP perception 4.63 (3.21-6.05), and MDP emotional score 2.37 (1.10-3.64). The estimates were consistent with small-to-moderate effect sizes using distributional analysis, and MCIDs were similar between COPD and non-COPD patients. The instruments were generally feasible and quick to use. Conclusion: D12 and MDP are responsive to change and feasible for use for assessing multidimensional breathlessness in outpatients with cardiorespiratory disease. MCIDs were determined for use as endpoints in clinical trials.

Tidskriftsartikel (refereegranskat)abstract
- Introduction Breathlessness is a cardinal symptom in cardiorespiratory disease. An instrument for measuring different aspects of breathlessness was recently developed, the Multidimensional Dyspnea Profile (MDP). This study aimed to validate the MDP in terms of the underlying factor structure, internal consistency, test-retest reliability and concurrent validity in Swedish outpatients with cardiorespiratory disease. Methods Outpatients with stable cardiorespiratory disease and breathlessness in daily life were recruited. Factor structure of MDP was analysed using confirmatory factor analysis; internal consistency was analysed using Cronbach's alpha; and test-retest reliability was analysed using intraclass correlation coefficients (ICCs) for patients with unchanged breathlessness between assessments (baseline, after 30-90 min and 2 weeks). Concurrent validity was evaluated using correlations with validated scales of breathlessness, anxiety, depression and health-related quality of life. Results In total, 182 outpatients with cardiorespiratory disease and breathlessness in daily life were included; 53.3% were women; main diagnoses were chronic obstructive pulmonary disease (24.7%), asthma (21.4%), heart failure (19.2%) and idiopathic pulmonary fibrosis (18.7%). The MDP total, immediate perception and emotional response scores, and individual item scores showed expected factor structure and acceptable measurement properties: internal consistency (Cronbach's alpha, range 0.80-0.93); test-retest reliability at 30-90 min and 2 weeks (ICC, range 0.67-0.91); and concurrent validity. There was no evidence of a learning effect. Findings were similar between diagnoses. Discussion MDP is a valid instrument for multidimensional measurement of breathlessness in Swedish outpatients across cardiorespiratory diseases.

Tidskriftsartikel (refereegranskat)abstract
- Dog trials and competitions involve various sport disciplines, e.g., obedience, agility, working dog trials and rally obedience. Dog handlers navigate their dogs through physically and mentally demanding tasks. The purpose of this study was to gain a better understanding of barriers and facilitators to canine health promotion and injury prevention described by dog handlers.Methods: Qualitative inductive content analysis was applied to systematically organize and interpret narrative data from 654 respondents' answers to open-ended questions in an anonymous online inquiry.Results: Two categories, with seven sub-categories, emerged from the analysis: (1) Challenges in applying the regulations in dog trials and competitions, and (2) Implementation of animal welfare and canine well-being approaches. Respondents described the challenges in applying regulations in dog trials and competitions and lack of scientific research as barriers to their intent to prevent injuries in their dogs. Implementation of animal welfare and canine well-being approaches were described as facilitators.Conclusion: The findings imply that the stakeholders continuously need to work on bridging possible gaps between the canine welfare criteria and the scientific and empirical knowledge in canine sports and performance medicine.

Tidskriftsartikel (refereegranskat)abstract
- Simple Summary Canine sporting competitions, e.g., agility, obedience, rally obedience, and utility trials, e.g., protection, tracking, search, and messenger, are physically and mentally demanding disciplines. There is a growing concern within the dog sports community that some disciplines and breeds may be at higher injury risk. This study aimed to describe the frequencies and types of injuries experienced amongst Swedish sporting and utility trial dogs and to explore associations between discipline, breed, sex, neuter status, age, and injury history. Through a questionnaire survey, information about 1582 dogs was collected. During their lifetime, more than half of the dogs (n = 928, 58.7%) had suffered from an injury whether it appeared during training, competition, or outside of sport. Key findings were that muscular, joint, and dermatologic injuries were most commonly reported and the most common injury locations were the thoracic, lumbar and lumbosacral spine, paw, head, shoulder, and stifle. In a multivariate analysis, Border Collies, Belgian Malinois, and higher age at the time of report increased the odds of injury history. Our results provide more understanding of injuries in sporting and utility dogs and contribute to injury prevention strategies that potentially enhance canine welfare.Abstract Canine sporting competitions, e.g., agility, obedience, rally obedience, and utility trials, e.g., protection, tracking, search, and messenger, are physically and mentally demanding disciplines. This study aimed to describe the types and frequencies of injuries experienced amongst Swedish sporting and utility trial dogs and to explore associations between discipline, breed, sex, neuter status, age, and injury history. Dog handlers provided information on competition-level dogs (n = 1582) through a cross-sectional survey. The overall proportion of dogs sustaining any injury during their lifetime, whether it was during competition, training, or outside of sport, was 58.7% (n = 928). Muscular, joint, and dermatologic injuries were most commonly reported and the most common injury locations were the thoracic, lumbar and lumbosacral spine, paw, head, shoulder, and stifle. According to multivariate analysis, Border Collie (adjusted OR 1.93), Belgian Malinois (adjusted OR 2.51) and higher age at the time of report (adjusted OR 1.81-9.67) increased the odds of injury history. Our results provide more understanding of injuries in sporting and utility dogs and contribute to injury prevention strategies that potentially enhance canine welfare.

-
Tidskriftsartikel (refereegranskat)abstract
- Objective: To explore physical activity patterns, including conditioning exercise and sport-specific training, and management routines utilized by handlers of Swedish sporting and working dogs participating in agility, obedience, rally obedience and working trial disciplines.Procedures: Dog handlers provided information on competition-level dogs through an internet-based cross-sectional and descriptive survey on physical activity, sport-specific training and management. Results are reported overall and stratified by participation in specific disciplines.Results: We received 1615 replies to the questionnaire. After data cleaning, 1582 dogs (98%) remained for the analysis. Of these, 430 participated in agility, 790 in obedience, 596 in rally obedience, and 847 dogs had competed in a working trial, i.e., messenger, protection, search or tracking. Number of disciplines performed by each dog varied between one and five. Most common was participation in one (n = 767, 48%) or two (n = 541, 34%) disciplines. Out of the dogs competing in one discipline, 38% (n = 294) were considered to be specialized as they actively trained only that discipline for >= 10 months per year. The vast majority of the dogs (n = 1129, 71%) received more than 1 h of daily physical activity, e.g., walks, and only n = 51 (3%) were never exercised off-leash. Preferred self-selected gait was trot (n = 907, 57%) and gallop (n = 499, 32%). A fifth (n = 319, 20%) never played with other dogs. The majority (n = 1328, 84%) received more than 1 h of vigorous physical conditioning exercise per week. Almost three quarters (n = 1119, 71%) participated in physical conditioning exercise. Two thirds (n = 953, 60%) participated in at least 3 h of sport-specific training per week and only a very small portion (n = 35, 2%) trained their specific discipline less than once per week. Median total work load, i.e., all daily physical activity, vigorous physical conditioning exercise and sport-specific training, was 16.5 h per week.Conclusion and clinical relevance: We observe physical activity at moderate to high durations and moderate to vigorous intensities among Swedish sporting and working trial dogs. Most dogs received physical conditioning exercise, but not all dogs were warmed up before training and competition. Our study provides veterinary professionals and dog trainers with valuable insights on the physical exposures and management routines of sporting and working trial dogs.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Self-efficacy can affect a child's ability to perform important activities, infuse him/her with a sense of control and is likely an integral target for successful treatment in pediatric pain rehabilitation. Modern physical therapy treatment includes behavioral aspects and valid measures of self-efficacy are important for both research and clinical practice. In this study, the aim was to develop and perform preliminary testing of a self-efficacy scale for children and adolescents with pain.METHODS: Children and adolescents participated, along with researchers and healthcare staff, in developing the Self-Efficacy in Daily Activities (SEDA) measure. A total of 109 children and adolescents seeking physical therapy treatment for pain lasting longer than 3 months responded to the SEDA. Pain and pain-related disability were assessed using the Functional Disability Inventory (FDI). Exploratory analyzes for testing validity and reliability - principal component analyses (PCA), intraclass correlation coefficients (ICCs) and bivariate correlations - were performed.RESULTS: The PCA revealed a 16-item SEDA and a three-component scale. The components represented self-efficacy for physical activities, self-efficacy for personal care and self-efficacy for daily exertion. Validity correlation analyses showed moderate association between SEDA and FDI, -0.72 (p < .01), and low correlation with pain intensity, -0.29 (p = .03).CONCLUSIONS: The 16-item SEDA has satisfactory psychometric properties in children moderately affected by long-term pain. Further validation of the SEDA in other populations and confirmatory analyses are warranted.

- Objective The aim was to evaluate the effects of cocreated internet-based stepped care (iCAN-DO) on anxiety, depression, posttraumatic stress, and health-related quality of life (HRQoL) in individuals with cancer and self-reported anxiety and/or depression symptoms, compared with standard care.Methods Clinically recruited individuals with breast, colorectal, or prostate cancer underwent online screening with the Hospital Anxiety and Depression Scale (HADS). Those with anxiety and/or depression symptoms (>7 on any of the HADS subscales) were randomized to iCAN-DO or standard care. iCAN-DO comprised psychoeducation and self-care strategies (step 1) and internet-based cognitive behavioral therapy (iCBT, step 2). Data were collected before randomization and at 1, 4, 7, and 10 months and analyzed with intention-to-treat regression analysis and randomization tests.Results Online screening identified 245 (27%) of 909 individuals who reported anxiety and/or depression symptoms. They were randomized to iCAN-DO (n = 124) or standard care (n = 121). Of them 49% completed the 10-month assessment, and in the iCAN-DO group 85% accessed step 1 and 13% underwent iCBT. iCAN-DO decreased the levels of symptoms of depression (−0.54, 95% confidence interval: −1.08 to −0.01, P < .05) and the proportion of individuals with symptoms of depression (P < .01) at 10 months, compared with standard care, according to HADS. There were no significant effects on anxiety, posttraumatic stress, or HRQoL.Conclusion Internet-based stepped care improves symptoms of depression in individuals with cancer. Further studies are needed to gain knowledge on how to optimize and implement internet-based support in oncology care.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Individuals with newly diagnosed cancer may experience impaired health in several aspects and often have a large need for information and support. About 30% will experience symptoms of anxiety and depression, with varying needs of knowledge and support. Despite this, many of these patients lack appropriate support. Internet-based support programs may offer a supplement to standard care services, but must be carefully explored from a user perspective.OBJECTIVE: The purpose of this study was to explore the participants' perceptions of the relevance and benefits of an internet-based stepped care program (iCAN-DO) targeting individuals with cancer and concurrent symptoms of anxiety and depression.METHODS: We performed a qualitative study with an inductive approach, in which we used semistructured questions to interview 15 individuals using iCAN-DO. We analyzed the interviews using content analysis.RESULTS: The analysis found 17 subcategories regarding the stepped care intervention, resulting in 4 categories. Participants described the need for information as large and looked upon finding information almost as a survival strategy when receiving the cancer diagnosis. iCAN-DO was seen as a useful, reliable source of information and support. It was used as a complement to standard care and as a means to inform next of kin. Increased knowledge was a foundation for continued processing of participants' own feelings. The optimal time to gain access to iCAN-DO would have been when being informed of the diagnosis. The most common denominator was feeling acknowledged and supported, but with a desire for further adaptation of the system to each individual's own situation and needs.CONCLUSIONS: Users saw the internet-based stepped care program as safe and reliable and used it as a complement to standard care. Similar interventions may gain from more personalized contents, being integrated into standard care, or using symptom tracking to adjust the contents. Offering this type of program close to diagnosis may provide benefits to users.TRIAL REGISTRATION: ClincalTrials.gov NCT-01630681; https://clinicaltrials.gov/ct2/show/NCT01630681.

Internet-based Psychosocial Support : Design, Effects and User Experience in the Cancer Setting
- 2020

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background and Aim Being diagnosed with cancer is often described as a major loss of control leading to severe psychological distress and symptoms of anxiety and depression can continue to affect the individual in the long term. The cancer and its treatment may influence all dimensions of health, thus the psychosocial support provided needs to be multifaceted and easy accessed. Internet-based interventions may be one way to provide such support, but evidence is limited. This thesis aimed to investigate the design, effects, and experiences of internet-based psychosocial support in cancer.Methods and Results Study 1 encompassed a co-creation development process resulting in the interactive support provided as the first step in an internet-based stepped care intervention (iCAN-DO). The effects of iCAN-DO were investigated in a randomised controlled trial, targeting individuals newly diagnosed with cancer and concurrent self-reported symptoms of anxiety and depression (according to the Hospital Anxiety and Depression Scale). Step 1 had a psycho-educative content involving self-care strategies and was available to the intervention group during the ten-month study period. Step 2 comprised a guided internet-based cognitive behavior therapy (iCBT) program and was offered those without improvement in anxiety and depression after using Step 1. The results showed that iCAN-DO improved symptoms of depression compared with standard care, while symptoms of anxiety were largely unaffected. Most participants used Step 1, while only a few used Step 2.In Study 2, aspects of usefulness, relevance, and usability in iCAN-DO were explored through qualitative interviews, analysed using content analysis. Results showed that standard healthcare did not meet the individuals' needs and iCAN-DO was used as complement, providing access to relevant, trustworthy information and support. Usability was affected by the perceived usefulness and ease of use of the intervention, as well as by the user´s circumstances in life and consequences of the cancer. The co-creation process in the development of Step 1 added relevance, but both steps 1 and 2 would have gained from being provided earlier, integrated into standard healthcare and more adaptable to the individual.Conclusion The thesis concluded that the internet-based intervention had positive effects on symptoms of depression in individuals newly diagnosed with cancer. Individuals with cancer experience several unmet needs in standard healthcare and since psycho-educative support including self-care advice seems feasible in this group, efforts are needed to incorporate internet-based support in regular oncology care. Since the intervention did not target all symptoms (i.e. anxiety) further research is needed on how to enhance efficacy and how to make iCBT more feasible for this group.

Physical activity and exercise during curative oncological treatment : exploring the effects of exercise intensity and behaviour change support, safety, and patients’ and exercise professionals’ experiences
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Aims: This thesis aimed to explore the effects of exercise intensity and behaviour change support (BCS), the safety of exercise, and experiences of exercise for both patients and exercise professionals during oncological treatment (e.g. neo/adjuvant chemotherapy, endocrine treatment, radiotherapy). This thesis is based on data from the Phys-Can (Physical training and Cancer) multicentre research program, consisting of a feasibility study, an observation study, and a randomised controlled trial (RCT). Methods: Paper I and II were quantitative studies. Paper I was a RCT with a 2x2 factorial design. Patients newly diagnosed with breast, prostate, or colorectal cancer about to start oncological treatment were randomised to six months of high intensity (HI) or low-moderate intensity (LMI) supervised group based resistance- and home-based endurance training, with or without additional BCS. The primary outcome, cancer related fatigue (CRF), was assessed by the Multidimensional Fatigue Inventory. Multiple linear regression and additional responder analysis for primary outcomes were performed. Paper II was a descriptive and comparative study based on secondary data from the observation study and RCT. Data were presented descriptively, and related factors to adverse events (AEs) were analysed with logistic regressions. Paper III and IV were qualitative studies. Participants were patients with breast, prostate, or colorectal cancer undergoing oncological treatment (Paper III) or coaches supervising exercise for participants in the RCT (Paper IV). Data were collected through semi-structured individual- (Paper III and IV) and focus group interviews (Paper III) and analysed with qualitative content analysis (Paper III) and thematic analysis (Paper IV). Main results and conclusions: The results from this thesis indicate that exercise at HI may not improve CRF in comparison with exercise at LMI in patients undergoing treatment, thus patients can be advised to exercise at either preferred intensity. Also, additional BCS did not improve CRF in relatively motivated patients receiving supervised exercise (Paper I). Furthermore, exercise-related AEs in persons undergoing oncological treatment are minor, of musculoskeletal origin, and with a similar incidence as in healthy populations. However, a higher risk of minor exercise-related AEs was reported in HI groups than in LMI groups. More serious AEs were rare, thus it seems safe to exercise even at HI for these patient groups (Paper II). The results also indicated that patients could experience side effects and concerns regarding the safety of exercising during oncological treatment as barriers to engage in physical activity. Therefore, engaging in physical activity before the onset of side effects from treatment and providing information regarding physical activity to patients could be beneficial (Paper III). Professionals supervising exercise for patients may find it highly rewarding, which is promising for implementation in cancer rehabilitation. However, patients may still receive contradictory information regarding the safety of exercise from health care staff, which can be difficult for exercise professionals to counteract (Paper IV).

- Introduction: Supervised exercise may improve physical function and quality of life during oncological treatment. Providing supervised exercise to all patients at hospitals may be impractical, with community-based settings (e.g. public gyms) as a possible alternative. To facilitate implementation, knowledge about the experiences of professionals who deliver exercise programs in community-based settings is crucial.Objective: To explore how physical therapists and personal trainers experience supervising exercise in a community-based setting for persons undergoing curative oncological treatment.Methods: Nine physical therapists and two personal trainers (coaches) were interviewed individually. The semi-structured interviews lasted 33-67 minutes and were analyzed using thematic analysis.Results: Two main themes emerged: "A meaningful task" and "A challenging task," with nine sub-themes. The coaches experienced supervising exercise for persons undergoing treatment as meaningful, as they became a link between oncology care and health promotion. They grew more confident in the role and ascertained that exercising during treatment was feasible. Challenges included managing side effects of treatment and contradictory information from oncology care staff at hospitals, advising patients not to exercise.Conclusion: Supervising exercise for persons undergoing oncological treatment in a community-based setting may be highly rewarding for professionals who deliver exercise programs, which is promising for implementation. However, patients receive contradictory information about exercise, which may prevent physical activity. Also, supervising exercise for persons undergoing oncological treatment requires skills training; this is suggested for inclusion in educational programs for physical therapists and others. Future research should focus on strategies for cooperation between oncology care and health promotion.

- Background: By mapping the existing literature on exercise oncology, gaps in knowledge can be identified, and future directions for research can be pointed out.Objectives: This review aimed to map diagnoses and outcome measures targeted in reviews and describe the effects on those outcomes. Further, the aim was to map exercise intervention characteristics being reviewed and the effects depending on these characteristics, and to discuss implications for future research.Methods: A systematic search was performed in PubMed, Cinahl, PSYCHInfo, and Cochrane Library. Reviews including physical activity and exercise intervention trials in adult patients during or after curative oncological treatment were included. Reference lists were scanned in order to find additional relevant papers.Results: Twenty-three reviews were included in the present study. The majority included mixed forms of cancers. Significant improvements were reported on physical fitness, cancer-related fatigue (CRF), health-related quality of life, physical function, psychological outcomes, lymphedema-related symptoms, biological markers, and physical activity level. Four reviews targeted time point for implementation of exercise intervention. There were slightly greater effects on CRF, physical fitness, and walking distance from implementation after completed treatment. Two reviews comparing exercise types reported superior effects from combinations of aerobic exercise and resistance training compared to aerobic or resistance training alone. One review targeted exercise intensity, and the results indicated a greater effect from moderately intense exercise compared to high intense exercise. One review assessed behaviour change techniques in exercise trials and suggested the use of programme goal-setting, self-monitoring, and generalization of behaviour to promote adoption and maintenance of exercise behaviour.Conclusion: Exercise seems to be beneficial during and after curative oncological treatment in several types of cancer. A higher reporting of exercise intervention details is essential in future exercise intervention trials and there is still a need for large, randomized trials, especially in forms of cancer other than breast cancer.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: The aim of the present single-centre randomised controlled trial was to assess the effect of a behavioural sleep medicine (BSM) intervention on obstructive sleep apnea (OSA) severity in patients who have been referred for new treatment with continuous positive airway pressure (CPAP).METHODS: After baseline assessment including ventilatory and anthropometric parameters, and physical activity monitoring, 86 patients who were overweight (BMI ≥ 25) and had moderate-severe OSA with apnea-hypopnea index (AHI) ≥ 15 were randomised into a control group (CG; CPAP and advice about weight loss) or an experimental group (ExpG; CPAP and BSM intervention targeting physical activity and eating behaviour). The BSM intervention comprised 10 individual sessions with a dietician and a physiotherapist and included behaviour change techniques such as goal setting and self-monitoring. After 6 months, a new recording of ventilatory parameters was performed without CPAP.RESULTS: In ExpG, 40% (n = 14) had improved from severe to moderate or mild OSA or from moderate to mild OSA compared to 16.7% in CG (n = 6, p = 0.02). Further, a lower AHI and amount body fat at baseline were correlated with improvement in severity class. Being in ExpG implied a mean improvement in AHI by 9.7 and an odds ratio of 4.5 for improving in severity classification.CONCLUSIONS: The results highlight the clinical importance of lifestyle modifications in conjunction with CPAP treatment in patients with OSA.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundThere is ambiguity about what measures to use to best identify physical activity and sedentary behavior, and agreement between methods for measuring physical activity and sedentary behavior in people with obstructive sleep apnea syndrome (OSAS) and obesity has not been evaluated.ObjectiveThe objective of this study was to examine the level of agreement between an accelerometer and a self-report questionnaire (International Physical Activity Questionnaire [IPAQ]) or a logbook for measuring time spent on moderate to vigorous physical activity and time spent sedentary in people with OSAS and obesity.DesignThis prospective study was a psychometric evaluation of agreement between measurement methods.MethodsThirty-nine people who were obese (mean body mass index 36.1 kg/m2, SD=4.35) and had moderate to severe OSAS (apnea-hypopnea index of ≥15) were consecutively recruited from a sleep clinic in Sweden. All were treated with continuous positive airway pressure and were waiting for a follow-up sleep evaluation.ResultsAgreement between the measurement methods was limited. For physical activity, the mean difference between the accelerometer and the IPAQ was 47 minutes, and the mean difference between the accelerometer and the logbook was 32 minutes. Agreement was limited for sedentary time as well; the mean difference between the accelerometer and the IPAQ was 114 minutes, and the mean difference between the accelerometer and the logbook was 86 minutes.LimitationsThe small sample size may affect the interpretation and generalizability of the results.ConclusionsThe results imply that the methods cannot be used interchangeably. A combination of an accelerometer and a daily logbook seems to provide a detailed description of physical activity and sedentary behavior.

Physical Activity and Eating Behaviour Changes in Patients with Obstructive Sleep Apnea Syndrome
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis aimed at developing and evaluating a tailored behavioural sleep medicine intervention for enhanced physical activity and healthy eating in patients with obstructive sleep apnea syndrome (OSAS) and overweight.Participants with moderate or severe OSAS (apnea-hypopnea index ≥15) and obesity (Studies I-II) or overweight (Studies III-IV), treated with continuous positive airway pressure (CPAP) (Studies I-II) or admitted to CPAP treatment (Studies III-IV), were recruited from the sleep clinic at Uppsala University Hospital, Sweden. Semi-structured individual interviews were analysed using qualitative content analysis (Study I). Data on moderate-to-vigorous physical activity (MVPA) and sedentary time were collected with three measurement methods and analysed regarding the level of measurement agreement (Study II). Potential disease-related and psychological correlates for the amount of MVPA, daily steps and sedentary time were explored using multiple linear regression (Study III). Physical activity and eating behaviour changes were examined after a six month behaviour change trial (Study IV). A tailored behavioural sleep medicine intervention targeting physical activity and healthy eating in combination with first- time CPAP treatment was compared with CPAP treatment and advice on the association between weight and OSAS.According to participants’ conceptions, a strong incentive is needed for a change in physical activity and bodily symptoms, external circumstances and thoughts and feelings influence physical activity engagement (Study I). Compared with accelerometry, the participants overestimated the level of MVPA and underestimated sedentary time when using self-reports (Study II). The participants spent 11 hours 45 minutes (71.6% of waking hours) while sedentary. Fear of movement contributed to the variation in steps and sedentary time. Body mass index was positively correlated to MVPA (Study III). The experimental group increased intake of fruit and fish and reduced more weight and waist circumference compared with controls. There were no changes in physical activity (Study IV).The novel tailored behavioural sleep medicine intervention combined with first-time CPAP facilitated eating behaviour change, with subsequent effects on anthropometrics, but it had no effects on physical activity and sedentary time. Fear of movement may be a salient determinant of sedentary time, which has to be further explored in this population. The results confirm sedentary being a construct necessary to separate from the lower end of a physical activity continuum and highlight the need of developing interventions targeting sedentary behaviours specifically.

- BackgroundThe aim of the study was to describe the amount of physical activity and sedentary time in patients with obstructive sleep apnea syndrome (OSAS) and overweight, and to explore potential disease-related and psychological correlates.MethodsA descriptive and correlational study was performed. Prospective data of physical activity and sedentary time were collected through accelerometry, and a one-point measurement of body mass index (BMI), daytime sleepiness, exercise self-efficacy, fear of movement, and depressive symptoms. Seventy-three participants with overweight (mean BMI 35kg/m2 SD 5) and moderate/severe OSAS (Apnea-Hypopnea Index >15) were consecutively recruited. Multivariate associations were determined through multiple linear regression analysis.ResultsThe participants took a daily average of 7734 (SD 3528) steps, spent an average of 77 (SD 54) minutes in moderate-to-vigorous physical activity (MVPA), and spent 11h 45 min (SD 2h 8 min) sedentary. BMI, daytime sleepiness, exercise self-efficacy, fear of movement, and depressive symptoms did not explain variance in MVPA or steps, but explained 22.9% of variance in sedentary time. In backward selection analysis, BMI contributed to the explanatory degree of MVPA with 9% whereas, fear of movement explained 6.3% of the variance in steps and 14.3% of the variance in sedentary time.ConclusionsAn important implication for future physical activity interventions is that both physical activity and sedentary behaviors should be targeted, and fear of movement may be an important determinant for change in patients with OSAS and overweight.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter comprises a review of physical activity and sedentary time among persons with obstructive sleep apnea syndrome (OSAS) and/or obesity. Different correlates of these behaviors are described and a discussion is offered regarding behavior change techniques for enhanced physical activity. Through increased energy expenditure, physical activity has a vital role in weight reduction. Additionally, regardless of weight change, physical activity reduces the risk of life-threatening diseases and there are promising results pointing to positive effects of physical activity on OSAS severity. Thus, physical activity and sedentary time are highly relevant to be addressed in the treatment of OSAS and obesity. Attending to an individual's prerequisites and strengthening self-efficacy, self-management, and self-regulation might encourage a behavior change in physical activity and sedentary time.

- This study aims to evaluate the effects on physical activity (PA) and eating behavior (EB) of a tailored behavioral medicine intervention and first-time continuous positive airway pressure (CPAP) treatment compared with first-time CPAP treatment and advice in patients with obstructive sleep apnea syndrome (OSAS) and overweight. Seventy-three patients (mean +/- SD, 55 +/- 12 years) with overweight (body mass index (BMI), 34.5 +/- 4.8) and moderate or severe OSAS (Apnea-Hypopnea Index, 41.7 +/- 20.9) scheduled for CPAP prescription were randomized to a control group (CPAP and advice on the association between weight and OSAS) or an experimental group (CPAP and a 6-month behavioral medicine intervention targeting PA and EB). At baseline and after 6 months, eating behavior (food frequency screening and Dutch Eating Behavior Questionnaire), weight, BMI, and waist circumference were assessed at one point, while PA and sedentary time were measured with accelerometry during 4 days. The experimental group reduced 2.1 kg (+/- 4.6) in weight and 3 cm (+/- 4.9) in waist circumference, significantly more than the control group. At 6 months, the experimental group ate more fruit and fish/shellfish than the control group. Low and moderate to vigorous PA did not change over time either within or between groups. Regarding BMI, steps, and sedentary time, there were within-group differences but no differences between groups. The behavioral medicine intervention did not change physical activity but facilitated changes in EB in patients with OSAS and overweight. The amount of weight loss and reduction in waist circumference favored the participants receiving this treatment. Since the strategies for achieving behavioral changes were tailored according to the individual's goals and personal functional behavioral analyses and progressed slowly in a graded manner, it might require higher PA quotas or a period longer than 6 months to reveal a behavioral change of larger proportions.

Tidskriftsartikel (refereegranskat)abstract
- Background: The internet-based stepped-care intervention iCAN-DO, used in the multicenter randomized controlled trial AdultCan, was developed for adult patients undergoing treatment for cancer and concurrently experiencing anxiety or depressive symptoms. iCAN-DO aimed to decrease symptoms of anxiety or depression. Step 1 comprises access to a library with psychoeducational material and a peer-support section, as well as the possibility to pose questions to a nurse. Step 2 of the intervention offers treatment consisting of internet-based cognitive behavioral therapy (iCBT) to participants still experiencing anxiety or depression at 1, 4, or 7 months after inclusion.Objective: The study aimed to explore user experiences of delivery, design, and structure of iCAN-DO from the perspective of people with cancer.Methods: We studied user experiences by interviewing 15 informants individually: 10 women with breast cancer (67%), 4 men with prostate cancer (27%), and 1 man with colorectal cancer (7%) with a mean age 58.9 years (SD 8.9). The interviews focused on informants' perceptions of ease of use and of system design and structure. Informants had been included in iCAN-DO for at least 7 months. They were purposefully selected based on activity in Step 1, participation in iCBT (ie, Step 2), gender, and diagnosis.Results: Of the 15 informants, 6 had been offered iCBT (40%). All informants used the internet on a daily basis, but 2 (13%) described themselves as very inexperienced computer users. The analysis revealed three subthemes, concerning how user experiences were affected by disease-specific factors and side effects (User experience in the context of cancer), technical problems (Technical struggles require patience and troubleshooting), and the structure and design of iCAN-DO (Appealing and usable, but rather simple).Conclusions: The results indicate that user experiences were affected by informants' life situations, the technical aspects and the design of iCAN-DO, and informants' preferences. The results have generated some developments feasible to launch during the ongoing study, but if iCAN-DO is to be used beyond research interest, a greater level of tailoring of information, features, and design may be needed to improve user experiences. The use of recurrent questionnaires during the treatment period may highlight an individual's health, but also function as a motivator showing improvements over time.

Comparison between logbook-reported and objectively-assessed physical activity and sedentary time in breast cancer patients : an agreement study
- 2017
-
Ingår i: BMC Sports Science, Medicine and Rehabilitation. - : BioMed Central (BMC). - 2052-1847. ; 9:1

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Increasing physical activity (PA) and decreasing sedentary time (ST) have important health effects among breast cancer patients, a growing population group. PA and sedentary behaviors are complex multi-dimensional behaviors and are challenging to monitor accurately. To date few studies have compared self-reports and objective measurement in assessing PA and ST in women undergoing breast cancer treatments. The aim of the present study was to compare self-reports and objective measures for assessing daily time spent in moderate-intensity physical activity (MPA), vigorous-intensity physical activity (VPA) and ST in women undergoing breast cancer treatments.METHODS: Baseline data from 65 women with breast cancer scheduled to undergo adjuvant treatment was included. Daily time spent in MPA, VPA and ST was assessed by a study-specific logbook and the SenseWear Armband mini (SWA). The level of agreement between the two measurement methods was then determined by performing Bland-Altman plots with limits of agreements, and calculating Spearman's rank correlation coefficients.RESULTS: The mean difference between the logbook and SWA with limits of agreement was 14 (±102) minutes for MPA, 1 (±21) minute for VPA and -196 (±408) minutes for ST, respectively. The logbook reported an average of 34 and 50% higher values than the SWA for MPA and VPA, as well as an average of 27% lower values for ST (P < 0.05). The Spearman's rank correlation coefficients showed that the differences between the methods increased as the average amount of time spent in PA and ST increased (P < 0.01).CONCLUSIONS: The results imply that the two measurement methods have limited agreement and cannot be used interchangeably.

- Self-perceptions of aging (SPA) is associated with various health-related outcomes, including physical performance. No previous study has investigated the potential predictive influence of SPA on physical performance among Swedish community-dwelling older adults. This was a cross-sectional study using a random sample of 153 Swedish community-dwelling individuals aged 70 and older. Multiple logistic regression analysis was performed, using the subscale “Attitude Towards Own Aging” of the Philadelphia Geriatric Center Morale Scale, as a measure of SPA. The Short Physical Performance Battery (SPPB) was dichotomized and used as the outcome variable. SPA was a significant predictor (OR = 1.546, CI = 1.066–2.243) of physical performance, adjusted for age, cognitive function, and life-space mobility. Further analyses revealed significant sex differences, with SPA not being included in the model for the men whilst it was still a significant predictor (OR = 1.689, CI = 1.031–2.765) of physical performance in the group of women. SPA plays a significant role in predicting physical performance among Swedish community-dwelling older adults. To further clarify this relationship and its consequences, future longitudinal research should focus on the relationship between SPA, physical performance, and fall risk.

Tidskriftsartikel (refereegranskat)abstract
- Study Objectives: Obstructive sleep apnea (OSA) is a disease with metabolic and cardiovascular consequences and is associated with decreased serum concentrations of insulin-like growth factor-1 (IGF-1). The aim of this study was to investigate whether continuous positive airway pressure (CPAP) will increase serum IGF-1 concentration in patients with OSA. Methods: Patients with moderate to severe OSA were recruited from a sleep clinic and serum IGF-1 was measured before initiation of CPAP and at follow-up after 4.8 +/- 2.5 months. Patients adherent to CPAP treatment (usage >= 4 h/night) were compared with those considered to be nonadherent (usage < 4 h/night). Results: Complete data were obtained from 69 patients (86% male, age 56 +/- 12 years, respiratory event index 43 +/- 21 events/h, Epworth Sleepiness Scale score 12 +/- 5). In those adherent to CPAP (n = 42), there was an increase in serum IGF-1 concentration with 21.1 (95% confidence interval [CI]: 13.1 to 29.2) mu g/L compared to 4.7 (95% CI: -4.1 to 13.5) mu g/L in the nonadherent group (n = 27) (P =.0083). In a linear multivariate model adjusting for sex, age, body mass index, respiratory event index, and mean oxygen saturation during the night recording, the change in serum IGF-1 concentration was significantly associated with adherence to CPAP treatment (adjusted beta coefficient: 21.8, 95% CI: 10.2 to 33.4) and inversely associated with change in body mass index (adjusted beta coefficient: -7.1, 95% CI: -11.3 to -3.0) and change in hemoglobin A1c (adjusted beta coefficient: -1.8, 95% CI: - 33 to -0.3). Conclusions: CPAP usage >= 4 h/night is associated with increased serum IGF-1 concentration in male patients with OSA.

Tidskriftsartikel (refereegranskat)abstract
- Study Objectives: Positive effects have been reported following a behavioral sleep medicine (BSM) intervention targeting physical activity and eating behavior in addition to continuous positive airway pressure (CPAP) treatment in patients with obstructive sleep apnea (OSA). Long-term follow-up remains to be explored. The aim was to examine the long-term effects of a tailored BSM intervention addressing physical activity and eating behavior in addition to CPAP treatment in patients with moderate to severe OSA combined with overweight and physical inactivity. Further, the aim was to identify variables at baseline, associated with treatment success regarding OSA severity. Methods: Sixty participants ( body mass index: 34.5 +/- 5.0 kg/m(2); apnea-hypopnea index [AHI]: 43.7 +/- 21.2 events/h) completed the randomized controlled trial with a follow-up at 18 months. The participants were randomized to either a control group treated with CPAP or an experimental group treated with CPAP and a BSM intervention targeting physical activity and eating behavior changes. OSA was categorized as mild (AHI: 5 to <14.9 events/h), moderate (AHI: 15 to <29.9 events/h), or severe (AHI >= 30 events/h). Results: Being in the experimental group was associated with a larger improvement (B = -9.353, P = .029) in AHI at the 18-month follow-up compared with being in the control group when adjusting for baseline AHI and body mass index. Improvement in OSA category occurred more frequently in the experimental group participants (n = 11; 36.7%) compared with the control group (n = 2; 6.7%). Deterioration in OSA category was found in 1 (3.3%) participant in the experimental group and 3 (10%) in the control group. Conclusions: The importance of a BSM intervention as an adjunct treatment in patients with OSA is emphasized due to its long-term benefits.

- Introduction Breathlessness is the cardinal symptom in both cardiac and respiratory diseases, and includes multiple dimensions. The multidimensional instrument Dyspnoea-12 has been developed to assess both physical and affective components of breathlessness. This study aimed to perform a clinical validation of the Swedish version of Dyspnoea-12 in outpatients with cardiorespiratory disease. Methods Stable outpatients with cardiorespiratory disease and self-reported breathlessness in daily life were recruited from five Swedish centres. Assessments of Dyspnoea-12 were performed at baseline, after 30-90 min and after 2 weeks. Factor structure was tested using confirmatory factor analysis and internal consistency using Cronbach's alpha. Test-retest reliability was analysed using intraclass correlation coefficients (ICCs). Concurrent validity at baseline was evaluated by examining correlations with lung function and several instruments for the assessment of symptoms and health status. Results In total, 182 patients were included: with the mean age of 69 years and 53% women. The main causes of breathlessness were chronic obstructive pulmonary disease (COPD; 25%), asthma (21%), heart failure (19%) and idiopathic pulmonary fibrosis (19%). Factor analysis confirmed the expected underlying two-component structure with two subdomains. The Dyspnoea-12 total score, physical subdomain score and affective subdomain scores showed high internal consistency (Cronbach's alpha 0.94, 0.84 and 0.80, respectively) and acceptable reliability after 2 weeks (ICC total scores 0.81, 0.79 and 0.73). Dyspnoea-12 showed concurrent validity with the instruments modified Medical Research Council scale, COPD Assessment Test, European Quality of Life-Five Dimensions-Five levels, the Functional Assessment of Chronic Illness Therapy-Fatigue, the Hospital Anxiety and Depression Scale, and with forced expiratory volume in 1 s in percentage of predicted value. The results were consistent across different cardiorespiratory conditions. Conclusion The Dyspnoea-12 is a valid instrument for multidimensional assessment of breathlessness in Swedish patients with cardiorespiratory diseases.

- BackgroundAdjuvant therapy may cause multiple sideeffects on long term health, including reduced cardiorespiratory fitness (CRF) in patients with breast cancer (1, 2). However, there is currently limited knowledge regarding the effect of different types of adjuvant cancer treatment on CRF in other cancer populations. The primary objective of the present study was to assess whether previously known correlates (age, diagnosis, initial CRF, physical activity level), type of adjuvant treatment and cancer-related fatigue were associated with changes in V˙O2max in patients with breast, prostate or colorectal cancer.MethodsProspective study with two time points of assessment, 85 patients scheduled for adjuvant cancer treatment were included. Cardiorespiratory fitness was assessed by V˙O2max during a maximal incremental exercise test on a treadmill before start of adjuvant therapy and again six months later. Physical activity level was recorded with a physical activity monitor (Sense Wear™ Mini) at baseline as average minutes of moderate-to-vigorous intensity physical activity (MVPA) per day. Physical fatigue at baseline was reported using the Multidimensional Fatigue Inventory-20 questionaire.ResultsIn multivariate linear regression analysis, 30 min higher daily MVPA at baseline was associated with a 5% higher V˙O2max at six months follow up when adjusted for adjuvant treatment (P = 0.010). Patients receiving adjuvant chemotherapy had a mean decline in V˙O2max of 10% (− 19, − 1; 95% confidence interval) compared to patients receiving adjuvant endocrine treatment (P = 0.028). Adjuvant radiotherapy, fatigue, age and diagnosis were not significantly associated with changes in V˙O2max.ConclusionThe results of the present study indicate that adjuvant chemotherapy is associated with a subsequent reduction in V˙O2max in patients with cancer whereas MVPA before start of adjuvant treatment is positively associated with a higher V˙O2max after end of adjuvant treatment.
