Review Meta AnalysisAnticoagulation for the initial treatment of venous thromboembolism in patients with cancer.
Compared to patients without cancer, patients with cancer receiving anticoagulant treatment for venous thromboembolism are more likely to develop recurrent venous thromboembolism (VTE). ⋯ Based on the included trials, LMWH is likely to be superior to UFH in the initial treatment of VTE in patients with cancer. However, there is a need for more trials to better address this research question in cancer patients. Moreover, researchers should consider making the raw data of RCTs available for individual patient data meta-analyses.

Review Meta AnalysisGlutamine supplementation to prevent morbidity and mortality in preterm infants.
Glutamine endogenous biosynthesis may be insufficient for tissue needs in states of metabolic stress. Trials in adults have suggested that glutamine supplementation improves clinical outcomes in critically ill adults. It has been suggested that glutamine supplementation may benefit preterm infants, particularly very low birth weight infants. ⋯ The available data from good quality randomised controlled trials indicate that glutamine supplementation does not confer benefits for preterm infants. The narrow confidence intervals for the effect size estimates suggest that a further trial of this intervention is not a research priority.

Many members of the public have negative attitudes towards antidepressants. Psychological interventions are more acceptable but require considerable therapist training. Acceptable psychological interventions that require less training and skill are needed to ensure increased uptake of intervention. A potential intervention of this sort is relaxation techniques. ⋯ Relaxation techniques were more effective at reducing self-rated depressive symptoms than no or minimal treatment. However, they were not as effective as psychological treatment. Data on clinician-rated depressive symptoms were less conclusive. Further research is required to investigate the possibility of relaxation being used as a first-line treatment in a stepped care approach to managing depression, especially in younger populations and populations with subthreshold or first episodes of depression.

ReviewChest physiotherapy for reducing respiratory morbidity in infants requiring ventilatory support.
Chest physiotherapy (CPT) has been used in many neonatal nurseries around the world to improve airway clearance and treat lung collapse; however, the evidence to support its use has been conflicting. Despite the large number of studies there is very little evidence of sufficiently good quality on which to base current practice. ⋯ The results of this review do not provide sufficient evidence on which to base clinical practice. There is a need for larger randomised controlled trials to address these issues.

ReviewSurgical versus medical treatment with cyclooxygenase inhibitors for symptomatic patent ductus arteriosus in preterm infants.
Patent ductus arteriosus (PDA) with significant left to right shunt in preterm infants increases morbidity and mortality. Early closure of the ductus arteriosus may be achieved pharmacologically using cyclooxygenase inhibitors or by surgery. The efficacy of both treatment modalities is well established. However, the preferred initial treatment of a symptomatic PDA in a preterm infant, surgical ligation or treatment with indomethacin, has not been well established. ⋯ The data regarding net benefit/harm are insufficient to make a conclusion as to whether surgical ligation or medical treatment with indomethacin is preferred as initial treatment for symptomatic PDA in preterm infants. It should be noted that three recent observational studies indicated an increased risk for one or more of the following outcomes associated with PDA ligation; chronic lung disease, retinopathy of prematurity and neurosensory impairment . It is possible that the duration of the "waiting-time" and transport to another facility with surgical capacity to have the PDA ligated could adversely affect outcomes, as could the perioperative care.
