To date, different intervention delivery methods have not been assessed. This study compared the effect of group-based exercise (GBE) to personal training (PT) in men undergoing ADT for PCa. Methods: 13 participants (mean age = 68.2, SD = 7.2) were randomly assigned to GBE or PT for 8 weeks. Participants exercised for 60 minutes three times per week at a moderate-vigorous intensity. Results: 10 participants completed the intervention. At post-intervention, the PT group improved: fatigue, systolic BP, waist circumference, body fat percentage, and maximal leg strength;participants in the GBE group improved leg strength. At 8 weeks, maximal upper body strength in the PT group was greater than the GBE group. There were no adverse events associated with moderate-high intensity training in this population of older men. Conclusion: PT may be more efficacious than GBE in improving several physical fitness outcomes and fatigue in men with PCa who are androgen deprived. Due to the small sample size and attrition, these results require cautious interpretation and confirmation from adequately powered trials.展开更多

A pilot control trial with qualitative interviews was undertaken within a university- community setting. Thirteen individuals who had experienced a stroke for periods of least 6 months (6 male, average 71 years) were assigned to the intervention group and 7 individuals (2 male, average age 67.9 years) assigned to the control group. Eight individuals from the intervention group completed a single interview. The procedures that related to recruitment and retention and data collection methods were considered. Outcome measures including;self-efficacy, falls self-efficacy and group membership, for both groups were taken at baseline, 11 weeks, 22 weeks. There was an additional assessment at 52 weeks for the intervention group. The structured interview was designed to focus on experiences of the intervention. Self-efficacy remained stable across time for both groups. An improvement in falls self-efficacy was noted in the intervention group at 11 weeks. Consistent improvement (from baseline) was observed in the identity scale across the 52 weeks. Qualitative data provided additional findings related to identity and confidence. Details considering recruitment and retention are also provided. This pilot study provided data that can be used for a further full-scale trial to be considered.展开更多

Our previous pilot study resulted in substantial adaptations of a cancer pain self-management intervention, the German PRO-Self? Plus Pain Control Program originally developed in the United States. This program will be implemented into clinical practice at the Medical Center-University of Freiburg. The purpose of this multiple methods pilot study is to test the implementation regarding feasibility and effects in clinical practice. In a randomized, wait-list controlled pilot study, adult oncology in-patients of a palliative care consultation service with pain >3/10 will be recruited. The intervention will be performed by a specialized advanced practice nurse with an in-hospital visit and, after discharge, via phone calls and visits. The follow-up will be personalized according to a clinical algorithm that factors in pain intensity, satisfaction with pain management, and patient adherence. The intervention includes structured and tailored components and is based on three key strategies: information, skill building and nurse coaching. The specific aims of this study are threefold: 1) to test the feasibility of the study and intervention procedures;2) to establish effect sizes of main outcome variables (e.g. decrease pain intensity, reduce the number of patients with pain as main symptom) for subsequent power calculation;3) to explore participants’ experiences with pain self-management support and their view of burden and benefit from study participation in a qualitative substudy. During the study period, which includes three data collection time points (T0 before, T1 one week and T2 six weeks after discharge), data will be collected via field notes of study nurses and questionnaires of patients. The results of this pilot study will build the basis for a larger comparative effectiveness study in which long term outcomes of a cancer pain self-management intervention in clinical practice will be evaluated.展开更多
