Low back pain is one of the most common and costly musculoskeletal problems in modern societies. Proponents of massage therapy claim it can minimize pain and disability, and speed return to normal function. ⋯ Based on the studies reviewed, there is insufficient evidence to recommend massage as a stand-alone treatment for non-specific low back pain. There is a need for high quality controlled trials to further evaluate the effects of massage for this condition.

Low back pain is a common reason for consulting a general practitioner, and advice on daily activities constitutes an important part in the primary care management of low back pain. ⋯ Bed rest compared to acvice to stay active will at best have small effects, and at worst might have small harmful effects on acute LBP. Differences in effects of advice to stay in bed compared with advice to stay active are small for patients with low back pain with or without sciatica. There is not an important difference in the effects of bed rest compared with exercises in the treatment of acute low back pain, or seven days compared with two to three days of bed rest in patients with low back pain of different duration with and without radiating pain.

ReviewNutritional supplementation for hip fracture aftercare in the elderly.
Fractures of the hip are an important cause of later ill health and mortality in elderly people. People with hip fractures are often malnourished at the time of fracture, and have poor food intake in hospital. ⋯ The strongest evidence for the effectiveness of nutritional supplementation exists for oral protein and energy feeds, but the evidence is still very weak. Future trials are required which overcome the defects of the reviewed studies, particularly inadequate size, methodology and outcome assessment.

ReviewCirculatory volume expansion for aneurysmal subarachnoid hemorrhage.
Patients with subarachnoid haemorrhage who develop spasm of the cerebral arteries may suffer from delayed cerebral ischaemia. This may be exacerbated by reduced circulatory volume. Intravenous fluid therapy to expand the circulating volume might reduce the risk of delayed cerebral ischaemia and so reduce the risk of neurological disability. ⋯ The effects of volume expansion therapy have not been studied properly in patients with aneurysmal subarachnoid haemorrhage. At present, there is no sound evidence for or against the use of volume expansion therapy in patients with aneurysmal subarachnoid haemorrhage.

ReviewAntioxidant vitamin and mineral supplementation for preventing age-related macular degeneration.
Some observational studies have suggested that people who eat a diet rich in antioxidant vitamins (carotenoids, vitamins C and E) or minerals (selenium and zinc) may be less likely to develop age-related macular degeneration. ⋯ There is no evidence to date that people without age-related macular degeneration should take antioxidant vitamin and mineral supplements to prevent or delay the onset of the disease. The results of five large ongoing trials are awaited.
