ReviewFolic acid and folinic acid for reducing side effects in patients receiving methotrexate for rheumatoid arthritis.
To assess the effects of folic acid and folinic acid in reducing the mucosal and gastrointestinal (GI) and haematologic side effects of low-dose of Methotrexate (MTX) in patients with Rheumatoid Arthritis (RA) and to determine whether or not folate supplementation alters MTX efficacy. ⋯ The results support the protective effect of folate supplementation in reducing MTX side effects related to the oral and GI systems. We could not determine if folic was different from folinic acid. Therefore, for folinic acid to be considered cost-effective it must be found more effective than folic acid at reducing MTX side effects.

Artemisinin derivatives are a relatively new group of drugs with antimalarial properties. As resistance to other antimalarial drugs continues to increase, artemisinin drugs may be useful alternatives. ⋯ The evidence suggests that artemisinin drugs are effective and safe for treating uncomplicated malaria. There is no evidence from randomised trials that one artemisinin derivative is better than the others. In areas where there is mefloquine resistance, combination therapy with an artemisinin derivative appears to improve sustained parasite clearance compared with either drug alone.

ReviewNeuraminidase inhibitors for preventing and treating influenza in healthy adults.
Influenza is an acute respiratory infection associated with raised temperature, headache, muscle ache and cough. The objective of this review was to assess the effects of neuraminidase inhibitors (NIs) in preventing cases of influenza and shortening or reducing the severity of influenza in healthy adults. A further objective was to estimate the frequency of adverse effects associated with NI administration. ⋯ NIs are effective for the prevention and treatment of influenza. Overall NIs are safe, although Oseltamivir causes significant nausea.

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.

ReviewOral protein calorie supplementation for children with chronic disease.
Growth failure and poor nutritional status are common features in children with chronic diseases due to reduced appetite, malabsorption and increased nutritional requirements associated with some diseases. The provision of oral protein calorie supplements is one of a number of interventions used to improve nutritional status in these children. The use of these products, which are expensive, may be associated with a number of adverse effects, for example, they may effect development of normal eating behaviour patterns or lead to unpleasant symptoms such as vomiting and diarrhoea. ⋯ Oral protein calorie supplements are widely used to improve the nutritional status of children with a number of chronic diseases. We have only been able to identify a small number of trials assessing these products in children with cystic fibrosis and have been unable to draw any conclusions based on the limited data extracted from these. We therefore recommend that a series of large, randomised controlled trials are undertaken investigating the use of these products in children with different chronic diseases. Until further data are available, we would suggest that these products are only used with caution.
