Review Meta AnalysisFormulas containing hydrolysed protein for prevention of allergy and food intolerance in infants.
Allergies and food reactions are common and may be associated with foods including adapted cow's milk formulas. Formulas containing hydrolysed proteins have been used to treat infants with allergy or food intolerance, and have been advocated for prevention of allergy and food intolerance in infants. ⋯ There is no evidence to support feeding with a hydrolysed formula for the prevention of allergy in preference to exclusive breast feeding. In high risk infants who are unable to be completely breast fed, there is evidence that prolonged feeding with a hydrolysed compared to a cow's milk formula reduces infant and childhood allergy and infant CMA. Further trials are required to determine if significant clinical benefits persist beyond 5 years of age and if there is any additional benefit from use of an extensive compared to a partially hydrolysed formula. Incremental costs of formula and the effect on compliance should be measured.

Some studies have suggested a protective effect of antioxidant nutrients on lung cancer. Observational epidemiological studies suggest an association between higher dietary levels of fruits and vegetables containing beta carotene and a lower risk of lung cancer. ⋯ There is currently no evidence to support recommending vitamins such as alpha-tocopherol, beta-carotene or retinol, alone or in combination, to prevent lung cancer. A harmful effect was found for beta-carotene with retinol at pharmacological doses in people with risk factors for lung cancer (smoking and/or occupational exposure to asbestos). More research from larger trials and with longer follow-up is needed to analyse the effectiveness of other supplements.

Multiple sclerosis (MS) patients are referred to occupational therapy with complaints about fatigue, limb weakness, alteration of upper extremity fine motor coordination, loss of sensation and spasticity that causes limitations in performance of activities of daily living and social participation. The primary purpose of occupational therapy is to enable individuals to participate in self-care, work and leisure activities that they want or need to perform. ⋯ On basis of this review no conclusions can be stated whether occupational therapy improves outcome in MS patients. The lack of (randomized controlled) efficacy studies in most intervention categories of OT shows an urgent need for future research in occupational therapy for multiple sclerosis. Initially, a survey of occupational therapy practice for MS patients including the characteristics and needs of these patients is necessary to develop a research agenda for efficacy studies.

ReviewArea-wide traffic calming for preventing traffic related injuries.
It is estimated that by 2020 road traffic crashes will have moved from ninth to third in the world disease burden ranking, as measured in disability adjusted life years, and second in developing countries. The identification of effective strategies for the prevention of traffic related injuries is of global health importance. Area-wide traffic calming schemes that discourage through traffic on residential roads is one such strategy. ⋯ The results from this review suggest that area-wide traffic calming in towns and cities may be a promising intervention for reducing the number of road traffic injuries, and deaths. However, further rigorous evaluations of this intervention are needed.

Although levodopa is the most common drug prescribed to relieve the symptoms of Parkinson's disease it is associated with motor and psychiatric side-effects. Consequently, interest has turned to alternative drugs with improved side-effect profiles to replace or augment levodopa. Amantadine, originally used as an antiviral drug, has been shown to improve the symptoms of Parkinson's disease. ⋯ A considerable amount of evidence on the effectiveness of amantadine has accrued from non-controlled trials, often in patients with Parkinsonian conditions other than idiopathic Parkinson's disease. However, rigorous analysis of the six randomised controlled trials of amantadine reveals insufficient evidence of its efficacy and safety in the treatment of idiopathic Parkinson's disease.
