Co-operativism and Local Development in Cuba consists of a series of pathbreaking essays on the role of co-operativism, and the new co-operatives, in the democratic transformation of Cuba and the government's plan to update the model.

We present a literature review of the role played by agricultural cooperatives in influenc-ing farm sustainability. We first focus on the theoretical literature to highlight the various economicbehaviours of cooperatives. Then we investigate all three dimensions of sustainability in developingand developed countries. We aim at linking the empirical findings to the theoretical understandingof cooperatives, in particular members' heterogeneity. This paper shows that cooperatives playa non-negligible role in farm economic sustainability and in the adoption of environmentallyfriendly practices, suggesting that both public policies and private initiatives in cooperatives maybe complementary. As regards social sustainability, there are only a few studies existing on the roleof agricultural cooperatives. The trade-off between economic and environmental sustainability incooperatives would need to be further investigated.

Background As the population ages, increasing numbers of older adults are undergoing surgery. Frailty is prevalent in older adults and may be a better predictor of post-operative morbidity and mortality than chronological age. The aim of this review was to examine the impact of frailty on adverse outcomes in the ‘older old’ and ‘oldest old’ surgical patients. Methods A systematic review was undertaken. Electronic databases from 2010 to 2015 were searched to identify articles which evaluated the relationship between frailty and post-operative outcomes in surgical populations with a mean age of 75 and older. Articles were excluded if they were in non-English languages or if frailty was measured using a single marker only. Demographic data, type of surgery performed, frailty measure and impact of frailty on adverse outcomes were extracted from the selected studies. Quality of the studies and risk of bias was assessed by the Epidemiological Appraisal Instrument. Results Twenty-three studies were selected for the review and they were assessed as medium to high quality. The mean age ranged from 75 to 87 years, and included patients undergoing cardiac, oncological, general, vascular and hip fracture surgeries. There were 21 different instruments used to measure frailty. Regardless of how frailty was measured, the strongest evidence in terms of numbers of studies, consistency of results and study quality was for associations between frailty and increased mortality at 30 days, 90 days and one year follow-up, post-operative complications and length of stay. A small number of studies reported on discharge to institutional care, functional decline and lower quality of life after surgery, and also found a significant association with frailty. Conclusion There was strong evidence that frailty in older-old and oldest-old surgical patients predicts post-operative mortality, complications, and prolonged length of stay. Frailty assessment may be a valuable tool in peri-operative assessment. It is possible that different frailty tools are best suited for different acuity and type of surgical patients. The association between frailty and return to pre-morbid function, discharge destination, and quality of life after surgery warrants further research.
