ReviewInterventions for preventing eating disorders in children and adolescents.
Eating disorders represent an extremely difficult condition to treat and patients consume an enormous amount of mental health energy and resources. Being young, female, and dieting are some of the few identified risk factors that have been reliably linked to the development of eating disorders, and several prevention eating disorder prevention programs have been developed and trialed with children and adolescents. The purpose of this systematic review is to evaluate the effectiveness of eating disorder prevention programs for children and adolescents both in the general population and those determined to be at risk. ⋯ The one significant pooled effect in the current review does not allow for any firm conclusions to be made about the impact of prevention programs for eating disorders in children and adolescents, although none of the pooled comparisons indicated evidence of harm. From a clinical perspective, the development and refinement of prevention programs is complicated by a lack of knowledge about risk factors associated with eating disorders and the need to strike a balance between delivering preventive interventions for eating disorders and considering the potential to cause harm. From a research perspective, the idea of "thresholds" for identifying young people at risk of developing eating disorders has been raised, and denial of concern or denial of illness represents a further issue complicating early identification in relation to eating disorder symptomatology. Longer-term effects of the intervention approaches will need to be monitored across development in order to demonstrate a decline in the incidence of eating disorders and associated risk factors.

ReviewRiluzole for amyotrophic lateral sclerosis (ALS)/motor neuron disease (MND).
Riluzole has been approved for treatment of patients with amyotrophic lateral sclerosis in many countries but not all. Questions persist about its clinical utility because of high cost, modest efficacy and concern over adverse effects. ⋯ Riluzole 100 mg daily is reasonably safe and probably prolongs survival by about two months in patients with amyotrophic lateral sclerosis. More studies are needed, especially to clarify its effect in older patients (over 75 years), and those with more advanced disease.

ReviewDopamine versus no treatment to prevent renal dysfunction in indomethacin-treated preterm newborn infants.
Indomethacin therapy for closure of patent ductus arteriosus frequently causes oliguria, and occasionally more serious renal dysfunction. Low dose dopamine has been suggested as a means for preventing this side effect. ⋯ There is no evidence from randomized trials to support the use of dopamine to prevent renal dysfunction in indomethacin-treated preterm infants.

The results from animal studies suggest that opioid antagonists may prevent the reinforcing effects of alcohol consumption. Based on the results of those animal studies, some opioid antagonists, such as, naltrexone, nalmefene, have been studied for their benefits in treating alcohol dependence. ⋯ NTX at the dose of 50 mg/day is effective for alcohol dependence in short-term treatment. The optimal duration of NTX treatment may be longer than 3 months. The evidence so far may be too little to support the superiority of NTX to acamprosate and the inferiority of NTX to disulfiram. NTX treatment should be concurrently given with a psychosocial intervention. Other patterns of NTX administration should not be used at present, e.g., a dose of three times a week, combined NTX with other biological treatments. NMF has no role for the treatment of alcohol dependence in clinical practice. Randomised, double-blind, placebo-controlled trials of NTX treatment in patients with alcohol dependence are still needed. Some issues should be concerned in further studies. Firstly, further trials should be conducted in larger sample sizes and over longer periods of time. Secondly, other than the outcomes relevant to alcohol use, some important outcomes should also be measured, e.g., functioning, health-related quality of life, economic cost. Thirdly, the comparisons between NTX and other treatments for alcohol dependence, both biological and psychosocial, should be investigated. Fourthly, combined treatments of NTX and other biological treatments for alcohol dependence may be in issue of interest. Lastly, high discontinuation rate in both treatment and control groups should be concerned.

Cerebral malaria is a common complication of Plasmodium falciparum infection, and kills over a million people every year. People with cerebral malaria become unconscious, and often have protracted convulsions. It is unclear whether giving anticonvulsant drugs routinely to people with cerebral malaria will improve the outcome of treatment and prevent death. ⋯ Routine phenobarbitone in cerebral malaria is associated with fewer convulsions but possibly more deaths. Further trials with adequate design, more participants, and different doses of anticonvulsant drugs are needed.
