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.

ReviewEffectiveness and cost effectiveness of counselling in primary care.
Counsellors are prevalent in primary care settings. However, there are concerns about the clinical and cost-effectiveness of the treatments they provide, compared with alternatives such as usual care from the general practitioner, medication or other psychological therapies. ⋯ Counselling is associated with modest improvement in short-term outcome compared to 'usual care', but provides no additional advantages in the long-term. Patients are satisfied with counselling, and it may not be associated with increased costs.

ReviewTracheal gas insufflation for the prevention of morbidity and mortality in mechanically ventilated newborn infants.
Tracheal gas insufflation (TGI) is a technique where a continuous flow of gas is instilled into the lower trachea during conventional mechanical ventilation. TGI can improve carbon dioxide removal with lower ventilation pressures and smaller tidal volumes, potentially decreasing secondary lung injury and chronic lung disease (CLD). ⋯ There is evidence from a single RCT that TGI may reduce the duration of mechanical ventilation in preterm infants - although the data from this small study do not give sufficient evidence to support the introduction of TGI into clinical practice. The technical requirements for performing TGI (as performed in the single included study) are great. There is no statistically significant reduction in the total duration of respiratory support or hospital stay. TGI cannot be recommended for general use at this time.

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.

Trials on the effect of systemic chemotherapy on survival and recurrence in adults with high-grade glioma have had inconclusive results. We undertook a systematic review and meta-analysis to assess the effects of such treatment on survival and recurrence. ⋯ This small but clear improvement in survival from chemotherapy encourages further study of drug treatment of these tumours
