Review Meta AnalysisPsychosocial and psychological interventions for preventing postpartum depression.
The cause of postpartum depression remains unclear, with extensive research suggesting a multi-factorial aetiology. However, epidemiological studies and meta-analyses of predictive studies have consistently demonstrated the importance of psychosocial and psychological variables. While interventions based on these variables may be effective treatment strategies, theoretically they may also be used in pregnancy and the early postpartum period to prevent postpartum depression. ⋯ Overall psychosocial interventions do not reduce the numbers of women who develop postpartum depression. However, a promising intervention is the provision of intensive, professionally-based postpartum support.

Review Meta AnalysisParent-training programmes for improving maternal psychosocial health.
Mental health problems are common and there is evidence to suggest that the origins of such problems lie in infancy and childhood. In particular, there is evidence from a range of studies to suggest that maternal psychosocial health can have a significant effect on the mother-infant relationship, and that this in turn can have consequences for both the short and long-term psychological health of the child. The use of parenting programmes is increasing in the UK and elsewhere and evidence of their effectiveness in improving outcomes for children has been provided. Evidence is now required of their effectiveness in improving outcomes for mothers. ⋯ It is suggested that parenting programmes can make a significant contribution to the short-term psychosocial health of mothers. However, there is currently a paucity of evidence concerning whether these results are maintained over time, and the limited follow-up data which are available show equivocal results. This points to the need for further evidence concerning the long-term effectiveness of parenting programmes on maternal mental health. Whilst the results of this review are positive overall, some studies showed no effect. Further research is needed to assess which factors contribute to successful outcomes in these programmes with particular attention being paid to the quality of delivery.These results suggest that parenting programmes have a potential role to play in the promotion of mental health.

Review Meta AnalysisRehabilitation after surgery for flexor tendon injuries in the hand.
Postoperative rehabilitation of the flexor tendons in the hand consists of a short period of immobilisation while pain and swelling diminish, followed by progressive mobilisation to maximize the range of motion of the affected fingers. By altering the time of immobilisation and the manner of subsequent mobilisation different rehabilitation regimes are created. ⋯ Controlled mobilisation regimens are widely employed in rehabilitation after flexor tendon repair in the hand. This review found insufficient evidence from randomised controlled trials to define the best mobilisation strategy.

Review Meta AnalysisSynchronized mechanical ventilation for respiratory support in newborn infants.
During synchronized mechanical ventilation, positive airway pressure and spontaneous inspiration coincide. Thus, if synchronous ventilation is provoked, adequate gas exchange should be achieved at lower peak airway pressures, potentially reducing barotrauma and hence airleak and chronic lung disease. Synchronous ventilation can be achieved by manipulation of rate and inspiratory time during conventional ventilation and employment of patient assisted ventilation. ⋯ Compared to conventional ventilation, benefit is demonstrated for both HFPPV and triggered ventilation with regard to a reduction in airleak and a shorter duration of ventilation, respectively. In none of the trials was complex respiratory monitoring undertaken and thus it is not possible to conclude that the mechanism of producing those benefits is by provocation of synchronized ventilation. Further trials are needed to determine whether synchronized ventilation is associated with other benefits, but optimization of trigger and ventilator design with respect to respiratory diagnosis is encouraged before embarking on further trials.

Review Meta AnalysisLong-term pharmacotherapy for obesity and overweight.
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.
