Multicenter Study
Beta blockers for elective surgery in elderly patients: population based, retrospective cohort study.
To test whether atenolol (a long acting beta blocker) and metoprolol (a short acting beta blocker) are associated with equivalent reductions in risk for elderly patients undergoing elective surgery. ⋯ Patients receiving metoprolol do not have as low a perioperative cardiac risk as patients receiving atenolol, in accord with possible acute withdrawal after missed doses.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Randomised controlled trial of prevention of falls in people aged > or =75 with severe visual impairment: the VIP trial.
To assess the efficacy and cost effectiveness of a home safety programme and a home exercise programme to reduce falls and injuries in older people with low vision. ⋯ The home safety programme reduced falls and was more cost effective than an exercise programme in this group of elderly people with poor vision. The Otago exercise programme with vitamin D supplementation was not effective in reducing falls or injuries in this group, possibly due to low levels of adherence. Trial registration number ISRCTN15342873.

Multicenter Study
Treatment of paediatric malaria during a period of drug transition to artemether-lumefantrine in Zambia: cross sectional study.
To evaluate treatment practices for uncomplicated malaria after the policy change from chloroquine to sulfadoxine-pyrimethamine and to artemether-lumefantrine in Zambia. ⋯ Although the use of chloroquine for uncomplicated malaria was successfully discontinued in Zambia, the change of drug policy towards artemether-lumefantrine does not necessarily translate into adequate use of this drug at the point of care.
