Cancer survivors’ experiences of a community-based cancer-specific exercise programme: results of an exploratory survey

Purpose Exercise levels often decline following cancer diagnosis despite growing evidence of its benefits. Treatment side-effects, older age, lack of confidence and opportunity to exercise with others in similar circumstances influence this. Our study explored the experiences of people attending a cancer-specific community-based exercise programme (CU Fitter™). Methods A survey distributed to those attending the programme gathered demographic/clinical information, self-reported exercise levels, information provision and barriers to/benefits of exercise. Results Sixty surveys were evaluable from 65/100 returned (62% female, 68% >60yrs, 66% breast/prostate cancer). Most (68%) were receiving treatment. 68% attended classes once or twice weekly. 55% received exercise advice after diagnosis, usually from their hospital doctor/nurse. More (73%) had read about exercising, but less used the internet to source information (32%). Self-reported exercise levels were higher currently than before diagnosis (p=0.05). 48% said their primary barrier to exercising was the physical impact of cancer/treatment. Improving fitness/health (40%) and social support (16%) were the most important gains from the programme. Many (67%) had made other lifestyle changes and intented to keep (50%), or increase (30%) exercising. Conclusions This community-based cancer-specific exercise approach engaged people with cancer and showed physical, psychological, and social benefits. Implications for cancer survivors Community grown exercise initiatives bring cancer survivors together creating their own supportive environment. Combining this with instructors familiar with the population and providing an open-ended service may prove particularly motivating and beneficial. Further work is required to provide evidence for this

Mechanical clearance of red blood cells by the human spleen: Potential therapeutic applications of a biomimetic RBC filtration method

International audienceDuring their lifespan, circulating RBC are frequently checked for their deformability. This mechanical quality control operates essentially in the human spleen. RBC unable to squeeze though narrow splenic slits are retained and cleared from the blood circulation. Under physiological conditions this prevents microvessels from being clogged by senescent, rigid RBC. Retention of poorly deformable RBC is an important determinant of pathogenesis in malaria and may also impact the clinical benefit of transfusion. Modulating the splenic retention of RBC has already been proposed to support therapeutic approaches in these research fields. To this aim, the development of microplates for high throughput filtration of RBC through microsphere layers (microplate-based microsphiltration) has been undertaken. This review focuses on potential therapeutic applications provided by this technology in malaria chemotherapy and transfusion
