Purpose: We aimed at updating the evidence found in controlled studies addressing general and event-free survival of cancer patients treated with the fermented mistletoe extract Iscador. Methods: The databases Embase, PubMed, CAMbase, Scopus, AMED and Cochrane were searched for clinical studies on cancer patients treated with Iscador. Quality of studies and risk of bias were evaluated according to the Cochrane guidelines and the Newcastle Ottawa Scale. Outcome data were expressed as hazard ratios (HR) and the respective 95% confidence intervals (CI). Meta-analysis was carried out using a random-effects model. Results: Eightytwo controlled studies met the inclusion criteria, of which 32 with 55 strata provided data for extracting HR and CI. The overall HR was 0.59 (95% CI: [0.53; 0.65], p < 0.0001) in favour of Iscador treatment. Heterogeneity of study results was moderate (I 2 = 50.9%; p < 0.0001, τ 2 = 0.053). Meta-regression did not reveal significant effects of sample size or study design. However, significant differences were found between cancer entities (p < 0.01), with most pronounced effects in cervical (HR = 0.43) and less pronounced effects in lung cancer (HR = 0.84). Conclusions: We found almost identical effects on cancer survival based on a broader database of higher quality. However, none of the studies was blinded and, therefore, there might be risk of performance bias. Implications for cancer survivors are as follows: findings indicate that adjuvant treatment of cancer patients with Iscador can be associated with a better survival.

BackgroundHospital staff experience high level of work stress and they have to find strategies to adapt and react to it. When they perceive emotional exhaustion and job dissatisfaction in response to constant work stress, one reaction might be emotional withdrawal. This emotional distancing can be seen as an adaptive strategy to keep ‘functionality’ in the job. Both, perception of emotional exhaustion and emotional distancing as a strategy, can be operationalized as ‘Cool Down’. We assume that work stress associated variables are positively associated with Cool Down reactions, while internal and external resources are negatively associated and might function as a buffer against emotional distancing. Moreover, we assume that the perception of stress and work burden might be different between nurses and physicians and women and men, but not their cool down reactions as a strategy.MethodsAnonymous cross-sectional survey with standardized instruments among 1384 health care professionals (66% nurses, 34% hospital physicians). Analyses of variance, correlation and also stepwise regression analyses were performed to analyze the influence of demands and resources on Cool Down reactions.ResultsAs measured with the Cool Down Index (CDI), frequency and strength of Cool Down reactions did not significantly differ between women and men, while women and men differ significantly for their burnout symptoms, stress perception and perceived work burden. With respect to profession, Cool Down and stress perception were not significantly different, but burnout and work burden. For nurses, “Emotional Exhaustion” was the best CDI predictor (51% explained variance), while in physicians it was “Depersonalization” (44% explained variance). Among putative resources which might buffer against Cool Down reactions, only team satisfaction and situational awareness had some influence, but not self-efficacy expectation.ConclusionThe perceptions of emotional exhaustion and distancing of nurses and physicians (and women and men) seems to be different, but not their adaptive Cool Down reactions. Data would support the notion that a structural approach of support would require first to control and eliminate work stressors, and second a multifaceted approach to strengthen and support hospital staff’s resources and resilience.Electronic supplementary materialThe online version of this article (doi:10.1186/s12913-017-2445-3) contains supplementary material, which is available to authorized users.

Context: Cancer-related fatigue (CRF) is one of the most burdensome symptoms in breast cancer survivors (BCSs), accompanied by reduced health-related quality of life (HRQOL). Objectives: This study investigated the influence of a multimodal therapy (MT; psychoeducation, eurythmy therapy, painting therapy, and sleep education/restriction), or a combination therapy (CT; MT plus aerobic training [AT]) on HRQOL in BCS with chronic CRF in comparison with AT alone. Methods: One hundred and twenty-six BCSs with CRF were included in a pragmatic comprehensive cohort study and allocated either per randomization or by preference to MT, CT, or AT. The EORTC QLQ-C30 core questionnaire was used to measure HRQOL. All analyses on HRQOL parameters were done in an explorative intention. Results: Patients were assigned to MT (n = 44), CT (n = 54), or AT (n = 28). CT was significantly superior to AT after 10 weeks of intervention (T1) in improving physical function. MT was found to have significant superiority over AT at T1 and T2 for physical functioning, emotional functioning, insomnia, and financial problems as well as role functioning, cognitive, social functioning, and fatigue 6 months later (T2). Conclusion: A multimodal approach appears to be a suitable concept for BCS with chronic CRF. A confirmatory study with larger samples should demonstrate the superiority of MT and adapted CT in HRQOL compared with the current treatment AT found in these explorative analyses.

Objectives: Parkinson disease (PD) is a neurodegenerative disorder with increasing impairments in disease progression. The aim of the pilot study was to investigate the influence of Tango argentino on the quality of life of people with PD compared to Tai Chi. Design, Setting, Interventions: In the two-arm, randomized controlled pilot study, patients with PD received a 10-week Tango argentino or Tai Chi intervention (once per week, 60 min each). Main Outcome Measures: The outcome parameters were assessed at three time points (after the 1st course, after the 5th course, and after the 10th course) using standardized instruments, i.e., Parkinson’s Disease Questionnaire-39 (PDQ-39), Brief Multidimensional Life Satisfaction Scale (BMLSS), Inner Congruence with Practices (ICPH). Results: Overall, 14 patients and their partners received Tango argentino (9 male, 5 female; mean age: 69 ± 8 years) and 15 received Tai Chi (3 male, 12 female; mean age: 69 ± 11 years). Four patients in each group were lost during the trial. No improvements were found in both groups for all outcomes. Patients in the tango group reported better emotional well-being (p = 0.039) after 10 weeks of intervention compared to the Tai Chi group. Conclusions: Further studies are needed taking into account findings from this study to improve recruitment and attrition of patients during the trial and to justify the potential implementation of Tango argentino into clinical care.

Background: We aim to compare the effectiveness of 3 active interventions, i.e., yoga, eurythmy therapy, and physiotherapeutic exercise, on chronic lower back pain. Methods: In this randomized controlled trial over 16 weeks (8 weeks of intervention, 8 weeks of follow-up), data of individuals with chronic lower back pain will be analyzed. Interventions are implemented as group sessions (75 min) once per week. Participants receive a manual for home-based practice and are assessed before and at the end of the 8-week intervention period, and at the end of an 8-week follow-up period. Standardized questionnaires are: the Roland-Morris Disability Score, visual analog scales measuring intensity of pain, the Brief Multidimensional Life Satisfaction Scale, the Perceived Stress Scale, the Inner Correspondence with the Practices questionnaire, the Freiburg Mindfulness Questionnaire, the General Self-Efficacy Scale, a self-regulation questionnaire, the Internal Coherence Scale, a pain diary (registering the need of analgesic medication), and a questionnaire on the patients' expectation that the interventions will be effective in reducing pain and how strong this reduction might be (2 single items), etc. Discussion: This large multicenter study will provide evidence on the effectiveness of 3 contrasting movement-orientated treatments that share some similarities but differ in essential details: yoga, eurythmy therapy, and physiotherapeutic exercises. It will provide important data on non-pharmacological options to treat lower back pain in a large group of affected individuals.

Background: The efficacy of specific interventions also of mind-body medicine is also dependent on the patients' ability to engage in these interventions and to perceive and change health-affecting attitudes and behaviors. The aim was to validate a 13-item instrument to measure (1) the patients' perception of specific attitudes and behaviors that are assumed to have a negative influence on the health situation, (2) their intention to change them, and (3) the implementation of the intended changes in their life affairs. Patients and Methods: Anonymous cross-sectional survey among 512 patients with chronic pain conditions (mean age 42.6 ± 11.4 years; 58% women) using standardized instruments. Results: After the elimination of 4 items, an explorative factor analysis of the 9 remaining items indicated 2 factors that would explain 57% of the variance: Perceptions/Intentions (5 items; Cronbach's alpha = 0.75) and Ability/ Implementation (4 items; alpha = 0.77). Factor 2 correlated moderately to strongly with internal adaptive coping strategies (AKU) and situational awareness (CPSC), and weakly with mental health (SF-36), life satisfaction (BMLSS), and low depressive symptoms (BDI) and escape from illness (Escape). Factor 1 correlated weakly with age and adaptive coping strategies (AKU). Conclusions: The final 9-item Perception, Intention and Ability to Change (PIAC) scale was approved as a short, practicable and promising instrument, which should be further evaluated in the context of training and intervention programs, particularly with respect to its predictive relevance.
