Review Meta AnalysisTailored interventions based on exhaled nitric oxide versus clinical symptoms for asthma in children and adults.
The measurement of severity and control of asthma in both children and adults can be based on subjective or objective measures. It has been advocated that fractional exhaled nitric oxide (FeNO) can be used to monitor airway inflammation as it correlates with some markers of asthma. Interventions for asthma therapies have been traditionally based on symptoms and/or spirometry. ⋯ Tailoring the dose of inhaled corticosteroids based on exhaled nitric oxide in comparison to clinical symptoms was carried out in different ways in the four studies that were found, and the results show only modest differences. The role of utilising exhaled nitric oxide to tailor the dose of inhaled corticosteroids is currently uncertain.

Review Meta AnalysisIbuprofen for the treatment of patent ductus arteriosus in preterm and/or low birth weight infants.
A patent ductus arteriosus (PDA) complicates the clinical course of preterm infants, increasing their risks of developing chronic lung disease (CLD), necrotizing enterocolitis (NEC), and intraventricular hemorrhage (IVH). Indomethacin is used as standard therapy to close a PDA, but is associated with reduced blood flow to the brain, kidneys and gastrointestinal tract. Ibuprofen, another cyclo-oxygenase inhibitor, may be as effective as indomethacin, with fewer side effects. ⋯ No statistically significant difference in the effectiveness of ibuprofen compared to indomethacin in closing a PDA was found. Ibuprofen compared with indomethacin reduces the risk of oliguria and is associated with lower serum creatinine levels following treatment. Pulmonary hypertension has been observed in three infants after prophylactic use of ibuprofen and one infant receiving ibuprofen for treatment in this review developed pulmonary hypertension. One additional case of pulmonary hypertension following treatment with ibuprofen to close a PDA was identified from the literature. The available data support the use of either drug for the treatment of a PDA. As both drugs are equally effective in closing a PDA, the clinician needs to weigh the potential side effects of one drug vs. the other when making a decision which drug to use. The most urgent research question to be answered is whether ibuprofen compared to indomethacin confers an improved rate of intact survival (survival without impairment) at 18 months corrected age and at the age of school entry.

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.

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 AnalysisGlucocorticoid corticosteroids for Duchenne muscular dystrophy.
Duchenne muscular dystrophy (DMD) is the most common muscular dystrophy of childhood. This incurable disease is characterised by muscle wasting and loss of walking ability leading to complete wheelchair dependence by 13 years of age. Prolongation of walking is one of the major aims of treatment. ⋯ There is evidence from randomised controlled studies that glucocorticoid corticosteroid therapy in Duchenne muscular dystrophy improves muscle strength and function in the short-term (six months to two years). The most effective prednisolone regime appears to be 0.75 mg/kg/day, given daily. In the short term, adverse effects were significantly more common but not clinically severe. Long-term benefits and hazards of glucocorticoid treatment cannot be evaluated from the currently published randomised studies. Non-randomised studies support the conclusions of functional benefits but also identify clinically significant adverse effects of long-term treatment. These benefits and adverse effects have implications for future research studies and clinical practice.
