Many members of the public have negative attitudes towards antidepressants. Psychological interventions are more acceptable but require considerable therapist training. Acceptable psychological interventions that require less training and skill are needed to ensure increased uptake of intervention. A potential intervention of this sort is relaxation techniques. ⋯ Relaxation techniques were more effective at reducing self-rated depressive symptoms than no or minimal treatment. However, they were not as effective as psychological treatment. Data on clinician-rated depressive symptoms were less conclusive. Further research is required to investigate the possibility of relaxation being used as a first-line treatment in a stepped care approach to managing depression, especially in younger populations and populations with subthreshold or first episodes of depression.

Review Meta AnalysisInterventions for treating wrist fractures in children.
Approximately a third of all fractures in children occur at the wrist, usually from falling onto an outstretched hand. ⋯ Limited evidence supports the use of removable splintage for buckle fractures and challenges the traditional use of above-elbow casts after reduction of displaced fractures. Although percutaneous wire fixation prevents redisplacement, the effects on longer term outcomes including function are not established. Further research is warranted on the optimum approach, including splintage, for buckle fractures; and on the use of below-elbow casts and indications for surgery for displaced wrist fractures in children.

Review Meta AnalysisInterventions for preventing injuries in the agricultural industry.
Agriculture is more hazardous than most other industries. Many strategies have been introduced to reduce injuries in the field, yet the effectiveness of different interventions on occupational injuries still remains unclear. ⋯ The selected studies provided no evidence that educational interventions are effective in decreasing injury rates among agricultural workers. Financial incentives could reduce injury rates. Legislation to ban pesticides could be effective. Legislation expanding the use of safety devices (ROPS) on new tractors was associated with a decrease in fatal injuries.

ReviewFolic acid with or without vitamin B12 for the prevention and treatment of healthy elderly and demented people.
Folate deficiency can result in congenital neural tube defects and megaloblastic anaemia. Low folate levels may be due to insufficient dietary intake or inefficient absorption, but impaired metabolic utilization also occurs.Because B12 deficiency can produce a similar anaemia to folate deficiency, there is a risk that folate supplementation can delay the diagnosis of B12 deficiency, which can cause irreversible neurological damage. Folic acid supplements may sometimes therefore include vitamin B12 supplements with simultaneous administration of vitamin B12.Lesser degrees of folate inadequacy are associated with high blood levels of the amino acid homocysteine which has been linked with the risk of arterial disease, dementia and Alzheimer's disease. There is therefore interest in whether dietary supplementation can improve cognitive function in the elderly.However, any apparent benefit from folic acid which was given in combination with B12 needs to be "corrected" for any effect of vitamin B12 alone. A separate Cochrane review of vitamin B12 and cognitive function has therefore been published. ⋯ The small number of studies which have been done provide no consistent evidence either way that folic acid, with or without vitamin B12, has a beneficial effect on cognitive function of unselected healthy or cognitively impaired older people. In a preliminary study, folic acid was associated with improvement in the response of people with Alzheimer's disease to cholinesterase inhibitors. In another, long-term use appeared to improve the cognitive function of healthy older people with high homocysteine levels. More studies are needed on this important issue.

ReviewInterventions for replacing missing teeth: maintaining and recovering soft tissue health around dental implants.
It is important to institute an effective supportive therapy to maintain or recover soft tissue health around dental implants. Different maintenance regimens have been suggested, however it is unclear which are the most effective. ⋯ There was only little reliable evidence for which are the most effective interventions for maintaining or recovering health of peri-implant soft tissues. The included RCTs had short follow-up periods and few subjects. There was not any reliable evidence for the most effective regimens for long term maintenance. This should not be interpreted as current maintenance regimens are ineffective. There was weak evidence that Listerine mouthwash, used twice a day for 30 seconds, as an adjunct to routine oral hygiene, is effective in reducing plaque and marginal bleeding around implants. More RCTs should be conducted in this area. In particular, there is a definite need for trials powered to find possible differences, using primary outcome measures and with much longer follow up. Such trials should be reported according to the CONSORT guidelines (http://www.consort-statement.org/).
