Review Meta Analysis
The effect of whole body vibration on balance, mobility and falls in older adults: a systematic review and meta-analysis.
This systematic review aimed to examine the effect of WBV on balance, mobility and falls among older adults. The databases used included MEDLINE, the Excerpta Medica database, the Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library Databases of Systematic Reviews, Physiotherapy Evidence Database (PEDro), PubMed, and Science Citation Index (last search in October 2011). Randomized controlled trials that investigated the effect of WBV on balance, mobility or falls in older adults were included in this review. ⋯ The effect of WBV on other balance/mobility outcomes and fall rate remains inconclusive. To conclude, WBV may be effective in improving relatively basic balance ability and mobility among older adults, particularly frailer ones. More good-quality WBV trials are required.

Despite the well-known association of obesity with increased mortality and the development of chronic diseases, an "obesity paradox" has been reported in several patient categories; i.e., overweight and obese patients have a better prognosis than normal or low-weight individuals. The present review aims to identify potential factors lying beneath the beneficial effect of overweight and obesity. In particular, the role of nutritional status, malnutrition and catabolic state, as well as intentional vs. unintentional weight loss and the possibility of a U-shape relationship between body mass index and survival will be examined. Furthermore, methodological considerations framing the obesity paradox will be presented and discussed.

Treating anaemia in older patients who have undergone hip fracture surgery is to enhance functional recovery. The relationship between peri-operative haemoglobin levels and outcome after hip fracture surgery are controversial. We assessed whether higher haemoglobin levels predict length of hospital stay after hip fracture surgery in elderly subjects. ⋯ Higher postoperative haemoglobin levels predict shorter length of hospital stay after hip fracture surgery in the elderly. A definitive randomized clinical trial has to demonstrate whether this association is causal.
