The feasibility of a multidimensional intervention in lymphoma survivors with chronic fatigue.

PURPOSE: Chronic fatigue (CF) affects 25-30% of lymphoma survivors, but interventions designed to reduce fatigue are lacking. The main aim of this study was to test the feasibility of a multidimensional intervention study in lymphoma survivors with CF. Secondary aims were to describe individual changes in fatigue, quality of life (QoL) and physical performance from pre (T0) to post (T1) intervention. METHODS: This feasibility study was as a one-armed intervention study performed in 2021. Hodgkin or aggressive non-Hodgkin lymphoma survivors received mailed study information and Chalder Fatigue Questionnaire and were asked to respond if they suffered from fatigue. The 12-week intervention included patient education, physical exercise, a cognitive behavioural therapy (CBT)-based group program and nutritional counselling. Feasibility data included patient recruitment, completion of assessments, adherence to the intervention and patient-reported experience measures. Participants responded to questionnaires and underwent physical tests at T0 and T1. RESULTS: Seven lymphoma survivors with CF were included. Of all assessments, 91% and 83% were completed at T0 and T1, respectively. Adherence to the interventional components varied from 69% to 91%. At T1, all participants rated exercise as useful, of whom five rated the CBT-based program and five rated individual nutritional counselling as useful. Five participants reported improved fatigue, QoL and physical performance. CONCLUSION: Lymphoma survivors with CF participating in a multidimensional intervention designed to reduce the level of fatigue showed high assessment completion rate and intervention adherence rate. Most of the participants evaluated the program as useful and improved their level of fatigue, QoL and physical performance after the intervention.

Work ability 8 years after breast cancer: exploring the role of social support in a nation-wide survey.

INTRODUCTION: As the 5-year survival rate after breast cancer in Norway is 92%, the population of breast cancer survivors (BCSs) is increasing. Knowledge of work ability in this population is scarce. In a population-based cohort of BCSs, we explored work ability 8 years after diagnosis and the association between work ability and social support, and cancer-related variables including late effects and lifestyle factors. METHODS: In 2019, all Norwegian women < 59 years when diagnosed with stage I-III breast cancer in 2011 or 2012, were identified by the Cancer Registry of Norway and invited to participate in a survey on work life experiences. Work ability was assessed using the Work Ability Index (scale 0-10). Factors associated with excellent work ability (score ≥ 9) were identified using univariate and multivariate logistic regression analyses, and adjusted for socioeconomic-, health- and cancer-related variables. RESULTS: Of the 1951 eligible BCSs, 1007 (52.8%) responded. After excluding survivors with relapse (n = 1), missing information on work ability score (n = 49), or work status (n = 31), the final sample comprised 926 BCSs within working age at survey (< 67 years). Mean age at survey was 56 years and 8 years (SD 0.7) had passed since diagnosis. Work ability had been reduced from 8.9 (SD 2.3) at diagnosis to 6.3 (SD 3.1). One in three BCSs reported poor work ability (WAS ≤ 5), and seven out of ten reported that their physical work ability had been reduced due to cancer. Social support from colleagues during cancer therapy was associated with excellent work ability, which was not observed for social support provided by supervisors or the general practitioner. Cognitive impairment and fatigue were inversely associated with work ability. None of the cancer-related variables, including treatment, were associated with work ability 8 years after diagnosis. CONCLUSION: In this population-based sample, one in three BCSs reported poor work ability 8 years after diagnosis. Collegial social support during cancer therapy appears to be a protective factor for sustained work ability, whilst survivors struggling with fatigue and cognitive impairments may represent a particularly vulnerable group for reduced work ability.

Work status changes and associated factors in a nationwide sample of Norwegian long-term breast cancer survivors.

PURPOSE: The study aims to describe work status at diagnosis and 8 years post-diagnosis in a nationwide sample of breast cancer survivors (BCSs), and investigate associated and self-reported factors of reduced work status. METHODS: Women aged 20-65 years when diagnosed with stage I-III breast cancer (BC) in 2011 or 2012 were invited to participate in a questionnaire study in 2019 (n = 2803), of whom 49% (n = 1361) responded. For this sub-study, we included 974 BCSs below the legal retirement age in Norway (< 67 years) at survey and with complete work status data. Reduced work status was defined as being in paid work at BC diagnosis and not working at time of survey. Logistic regression analyses were applied to identify factors associated with reduced work status. RESULTS: Of BCSs who were in paid work at diagnosis (n = 845), 63% maintained their work status to 8 years later. Reduced work status was associated with not living with children (OR .44, 95% CI .24-.82), age (OR 1.16, 95% CI 1.11-1.21), chemotherapy (OR 2.83, 95% CI 1.24-6.61), > 2 comorbid conditions (OR 2.27, 95% CI 1.16-4.32), cognitive function (OR .99, 95% CI .98-.99), fatigue (OR 1.02, 95% CI 1.01-1.03), and neuroticism (OR 1.57, 95% CI 1.00-2.46). BC and late effects were reported as reasons for reduced work status and disability. CONCLUSIONS: The majority of BCSs who were in paid work at diagnosis were working 8 years later. IMPLICATIONS FOR CANCER SURVIVORS: Our results suggest a need to focus on fatigue and reduced cognitive function among long-term BCSs, with the ultimate aim of improving work sustainability.

Some connections between importance sampling and enhanced sampling methods in molecular dynamics.

In molecular dynamics, enhanced sampling methods enable the collection of better statistics of rare events from a reference or target distribution. We show that a large class of these methods is based on the idea of importance sampling from mathematical statistics. We illustrate this connection by comparing the Hartmann-Schütte method for rare event simulation (J. Stat. Mech. Theor. Exp. 2012, P11004) and the Valsson-Parrinello method of variationally enhanced sampling [Phys. Rev. Lett. 113, 090601 (2014)]. We use this connection in order to discuss how recent results from the Monte Carlo methods literature can guide the development of enhanced sampling methods.

Sequences of talk about emotional concerns in follow-up consultations with adolescent childhood cancer survivors.

OBJECTIVE: To explore practices regarding communication about emotional concerns in follow-up consultations with adolescent cancer survivors and pediatrician. METHOD: Seven video-taped follow-up consultations with adolescent survivors which contained many examples of emotional cues and concern were analyzed according to principles of conversation analysis. RESULTS: During talk about emotional concerns, a task-focused asymmetric pattern of pediatrician questions and patient responses was most often upheld. In a number of cases a gradual build-up of emotional expression from a weak hint to a more explicit expression of emotional concern was observed, often facilitated by the pediatricians. Most often work-up was relatively brief, sometimes with a brief positive reappraisal, but more comprehensive elaboration was also seen. Topic shifts were often abrupt. CONCLUSION: Pediatricians and patients used some of the same conventions as in everyday conversation during emotional talk in medical encounters. We observed shifts between informal talk and a typical task-focused mode. Conscious attention to such shifts and to the sequential nature of emotional talk could be helpful for doctors in designing their responses to patients' emotional concerns. PRACTICE IMPLICATIONS: Our findings may contribute to insight in how clinicians respond to emotional concerns in follow-up consultations and have implications for communication skills training.

Depression in advanced cancer--assessment challenges and associations with disease load.

BACKGROUND: Patients with advanced cancer commonly experience multiple somatic symptoms and declining functioning. Some highly prevalent symptoms also overlap with diagnostic symptom-criteria of depression. Thus, assessing depression in these patients can be challenging. We therefore investigated 1) the effect of different scoring-methods of depressive symptoms on detecting depression, and 2) the relationship between disease load and depression amongst patients with advanced cancer. METHODS: The sample included 969 patients in the European Palliative Care Research Collaborative-Computer Symptom Assessment Study (EPCRC-CSA). Inclusion criteria were: incurable metastatic/locally advanced cancer and ≥ 18 years. Biomarkers and length of survival were registered from patient-records. Depression was assessed using the Patient Health Questionnaire (PHQ-9) and applying three scoring-methods: inclusive (algorithm scoring including the somatic symptom-criteria), exclusive (algorithm scoring excluding the somatic symptom-criteria) and sum-score (sum of all symptoms with a cut-off ≥ 8). RESULTS: Depression prevalence rates varied according to scoring-method: inclusive 13.7%, exclusive 14.9% and sum-score 45.3%. Agreement between the algorithm scoring-methods was excellent (Kappa = 0.81), but low between the inclusive and sum scoring-methods (Kappa = 0.32). Depression was significantly associated with more pain (OR-range: 1.09-1.19, p < 0.001-0.04) and lower performance status (KPS-score, OR-range = 0.68-0.72, p < 0.001) irrespective of scoring-method. LIMITATIONS: Depression was assessed using self-report, not clinical interviews. CONCLUSIONS: The scoring-method, not excluding somatic symptoms, had the greatest effect on assessment outcomes. Increasing pain and poorer than expected physical condition should alert clinicians to possible co-morbid depression. The large discrepancy in prevalence rates between scoring-methods reinforces the need for consensus and validation of depression definitions and assessment in populations with high disease load.

Emotional concerns in follow-up consultations between paediatric oncologists and adolescent survivors: a video-based observational study.

OBJECTIVE: The present study aimed to explore (a) to what extent adolescent cancer survivors express emotional concerns during follow-up consultations, (b) the content of these expressions, and (c) the responses to their concerns by the paediatric haemato-oncologists (oncologists). METHODS: Sixty-six follow-up consultations between adolescent patients (aged 12-20 years old; mean = 16) and oncologists (n = 10) were video recorded. Emotional concerns were coded using the Verona coding definitions of emotional sequences (VR-CoDES). The content of the concerns was analysed using thematic analysis. RESULTS: Emotional concerns (n = 115) were identified in 50% of the consultations. Of the concerns, 87% were expressed implicitly as hints to the underlying emotion (cues) rather than explicitly (concerns). The oncologists elicited 66.9% of these expressions. Four main categories of emotional concerns were identified in the thematic analysis: physical (31%), psychological (29%), social (17%), and cancer related (23%). The majority (76.5%) of the oncologists' responses to the cues and/or concerns provided space for further disclosure. The oncologists responded less explicitly to the emotional aspects of physical and cancer-related issues in comparison with the cues or concerns of psychological origin. More cues and concerns were expressed when parents were not present in the consultation. CONCLUSIONS: In this study, almost half of the adolescent patients presented emotional concerns, and a subgroup presented many concerns; these were mainly expressed when initiated by the oncologists. Oncologists should therefore be attentive to hints to underlying emotions to help the adolescent bring forward his or her concerns.
