Randomized Controlled Trial Multicenter StudyThe 3Mg trial: a randomised controlled trial of intravenous or nebulised magnesium sulphate versus placebo in adults with acute severe asthma.
Magnesium sulphate, administered by the intravenous (i.v.) or inhaled (nebulised) route, has been proposed as a treatment for adults with acute severe asthma. Existing trials show mixed results and uncertain evidence of benefit. ⋯ We were unable to demonstrate a clinically worthwhile benefit from magnesium sulphate in acute severe asthma. There was some weak evidence of an effect of i.v. magnesium sulphate on hospital admission, but no evidence of an effect on VAS breathlessness or PEFR compared with placebo. We found no evidence that nebulised magnesium sulphate was more effective than placebo.

ReviewPercutaneous vertebroplasty and percutaneous balloon kyphoplasty for the treatment of osteoporotic vertebral fractures: a systematic review and cost-effectiveness analysis.
Percutaneous vertebroplasty (PVP) is a minimally invasive surgical procedure in which bone cement is injected into a fractured vertebra. Percutaneous balloon kyphoplasty (BKP) is a variation of this approach, in which an inflatable balloon tamp is placed in the collapsed vertebra prior to cement injection. ⋯ The National Institute for Health Research Health Technology Assessment programme.

ReviewIvacaftor for the treatment of patients with cystic fibrosis and the G551D mutation: a systematic review and cost-effectiveness analysis.
Ivacaftor (Kalydeco(®), Vertex Pharmaceuticals) is the first of a new class of drugs that target the underlying protein defect in cystic fibrosis (CF). It is aimed at patients with the G551D (glycine to aspartate change in nucleotide 1784 in exon 11) mutation; 5.7% of patients with CF in the UK have this mutation. ⋯ The National Institute for Health Research Health Technology Assessment programme.

Randomized Controlled TrialStructured, intensive education maximising engagement, motivation and long-term change for children and young people with diabetes: a cluster randomised controlled trial with integral process and economic evaluation - the CASCADE study.
Type 1 diabetes (T1D) in children and young people is increasing worldwide with a particular increase in children under the age of 5 years. Fewer than one in six children and young people achieve glycosylated fraction of haemoglobin (HbA1c) values in the range identified as providing best future outcomes. There is an urgent need for clinic-based pragmatic, feasible and effective interventions that improve both glycaemic control and quality of life (QoL). The intervention offers both structured education, to ensure young people know what they need to know, and a delivery model designed to motivate self-management. ⋯ A high-quality, complex, pragmatic trial of structured education can be successfully conducted alongside standard care in NHS diabetes clinics. Pragmatic components of a NICE-compliant structured education programme can be successfully delivered following a relatively brief 2-day training while paediatric health-care professionals benefit from training in behaviour change skills. The study provides invaluable information on barriers and opportunities regarding future, similar interventions. A low dropout rate and good attendance for the subgroup that attended the intervention suggests there might be improved uptake if offered to young people with lower HbA1c. Testing whether this approach can be more successful with a robust ongoing supervisory element should be a target of further research.

ReviewRoutine echocardiography in the management of stroke and transient ischaemic attack: a systematic review and economic evaluation.
Identification of the underlying cause of stroke and transient ischaemic attack (TIA) is important so that preventative therapy can be used to reduce the risk of recurrence. Transthoracic echocardiography (TTE) and transoesophageal echocardiography (TOE) are diagnostic tools used to identify those cardiac sources of stroke that may respond to treatment. ⋯ The National Institute for Health Research Health Technology Assessment programme.
