The patient with diabetes has many different learning needs relating to diet, monitoring, and treatments. In many health care systems specialist nurses provide much of these needs, usually aiming to empower patients to self-manage their diabetes. The present review aims to assess the effects of the involvement of specialist nurse care on outcomes for people with diabetes, compared to usual care in hospital clinics or primary care with no input from specialist nurses. ⋯ The presence of a diabetes specialist nurse / nurse case manager may improve patients' diabetic control over short time periods, but from currently available trials the effects over longer periods of time are not evident. There were no significant differences overall in hypoglycaemic episodes, hyperglycaemic incidents, or hospital admissions. Quality of life was not shown to be affected by input from a diabetes specialist nurse/nurse case manager.

ReviewAmino acids for amyotrophic lateral sclerosis / motor neuron disease.
Amyotrophic lateral sclerosis, also known as motor neuron disease, is a progressive neuromuscular disease that causes disability and eventual death. Various amino acid preparations, the three branched-chain amino acids (L-leucine, L-valine and L-isoleucine) or, alternatively, L-threonine have been used as experimental therapy. ⋯ There is no evidence to support a beneficial effect of either branched-chain amino acids or L-threonine in amyotrophic lateral sclerosis/motor neuron disease.

ReviewSingle versus double intrauterine insemination (IUI) in stimulated cycles for subfertile couples.
Intra uterine insemination (IUI), with or without controlled ovarian hyperstimulation (COH), is one of the treatment modalities offered to couples who have tried to conceive for at least one year (subfertile couples). It has been suggested that increasing the number of inseminations from one per cycle to two might increase the probability of conception. ⋯ Based on the results of pregnancy rate per couple of two trials, double intrauterine insemination showed no significant benefit over single intrauterine insemination in the treatment of subfertile couples with husband semen. There are no meaningful data to offer advice regarding clinical practice on the basis of this review.

Olanzapine, an atypical antipsychotic, is used in the treatment of mania both as monotherapy and combined with other medicines. ⋯ Olanzapine is an effective treatment for mania and may be more efficacious than divalproex, though leads to more weight gain. Clinicians should consider both the relative efficacy and the different incidence of specific adverse effects of available drugs.

Worldwide prevalence rates of obesity and overweight are rising and safe and effective treatment strategies are urgently needed. A number of anti-obesity agents have been studied in short-term clinical trials, but long-term efficacy and safety need to be established. ⋯ Studies evaluating the long-term efficacy of anti-obesity agents are limited to orlistat and sibutramine. Both drugs appear modestly effective in promoting weight loss; however, interpretation is limited by high attrition rates. Longer and more methodologically rigorous studies of anti-obesity drugs that are powered to examine endpoints such as mortality and cardiovascular morbidity are required to fully evaluate any potential benefit of such agents.
