Overall our study supports the use of anti-IL-5 treatments as an adjunct to standard of care in people with severe eosinophilic asthma and poor control. These treatments roughly halve the rate of asthma exacerbations in this population. There is limited evidence for improved HRQoL scores and lung function, which may not meet clinically detectable levels. There were no safety concerns regarding mepolizumab or reslizumab, and no excess serious adverse events with benralizumab, although there remains a question over adverse events significant enough to prompt discontinuation.Further research is needed on biomarkers for assessing treatment response, optimal duration and long-term effects of treatment, risk of relapse on withdrawal, non-eosinophilic patients, children (particularly under 12 years), and comparing anti-IL-5 treatments to each other and, in people eligible for both, to anti-immunoglobulin E. For benralizumab, future studies should closely monitor rates of adverse events prompting discontinuation.

Background Planned caesarean delivery for women thought be in preterm labour may be protective for baby, but could also be quite traumatic for both mother and baby. The optimal mode of delivery of preterm babies for both cephalic and breech presentation remains, therefore, controversial. Objectives To assess the effects of a policy of planned immediate caesarean delivery versus planned vaginal birth for women in preterm labour. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (24 April 2012). Selection criteria Randomised trials comparing a policy of planned immediate caesarean delivery versus planned vaginal delivery for preterm birth. Data collection and analysis Two review authors independently assessed trials for inclusion. Two review authors independently extracted data and assessed risk of bias. Data were checked for accuracy. Main results We included six studies (involving 122 women) but only four studies (involving only 116 women) contributed data to the analyses. Infant There were very little data of relevance to the three main (primary) outcomes considered in this review: There was no significant difference between planned immediate caesarean section and planned vaginal delivery with respect to birth injury to infant (risk ratio (RR) 0.56, 95%, confidence interval (CI) 0.05 to 5.62; one trial, 38 women) or birth asphyxia (RR 1.63, 95% CI 0.84 to 3.14; onetrial, 12 women). The only cases of birth trauma were a laceration of the buttock in a baby who was delivered by caesarean section and mild bruising in another allocated to the group delivered vaginally. The difference between the two groups with regard to perinatal deaths was not significant (0.29, 95% CI 0.07 to 1.14; three trials, 89 women) and there were no data specifically relating to neonatal admission to special care and/or intensive care unit. There was also no difference between the caesarean or vaginal delivery groups in terms of markers of possible birth asphyxia (RR 1.63, 95% CI 0.84 to 3.14; one trial, 12 women) or Apgar score less than seven at five minutes (RR 0.83, 95% CI 0.43 to 1.60; four trials, 115 women) and no difference in attempts at breastfeeding (RR 1.40, 95% 0.11 to 17.45; one trial, 12 women). There was also no difference in neonatal fitting/seizures (RR 0.22, 95% CI 0.01 to 4.32; three trials, 77 women), hypoxic ischaemic encephalopathy (RR 4.00, 95% CI 0.20 to 82.01;one trial, 12 women) or respiratory distress syndrome (RR 0.55, 95% CI 0.27 to 1.10; three trials, 103 women). There were no data reported in the trials specifically relating to meconium aspiration. There was also no significant difference between the two groups for abnormal follow-up in childhood (RR 0.65, 95% CI 0.19 to 2.22; one trial, 38 women) or delivery less than seven days after entry (RR 0.95, 95% CI 0.73 to 1.24; two trials, 51 women). Mother There were no data reported on maternal admissions to intensive care. However, there were seven cases of major maternal postpartum complications in the group...

Combination ICS and LABA offer some clinical benefits in COPD compared with ICS alone, especially for reduction in exacerbations. This review does not support the use of ICS alone when LABAs are available. Adverse events were not significantly different between treatments. Further long-term assessments using practical outcomes of current and new 24-hour LABAs will help determine their efficacy and safety. For robust comparisons as to their relative effects, long-term head-to-head comparisons are needed.

BackgroundBronchiectasis is predominantly an acquired disease process that represents the end stage of a variety of unrelated pulmonary insults. It is defined as persistent irreversible dilatation and distortion of medium-sized bronchi. It has been suggested that with widespread use of high-resolution computed tomography, more bronchiectasis diagnoses are being made. Patients diagnosed with bronchiectasis frequently have di iculty expectorating sputum. Sputum therefore is retained in the lungs and may become infected, leading to further lung damage. Mucolytic agents target hypersecretion or changed physiochemical properties of sputum to make it easier to clear. One drug, recombinant human DNase, breaks down the DNA that is released at the site of infection by neutrophils.Mucus clearance along with antimicrobial therapy remains an integral part of bronchiectasis management. Chest physiotherapy along with mucolytic agents is commonly used in practice without clear supportive evidence. ObjectivesTo determine whether ingested or inhaled mucolytics are e ective in the treatment of patients with bronchiectasis. Search methodsWe searched the Cochrane Airways Group Specialised Register and reference lists of relevant articles. We contacted experts in the field and drug companies. Searches were current as of June 2013. Selection criteriaRandomised trials of mucolytic treatment in people with bronchiectasis but not cystic fibrosis. Data collection and analysisData extraction was performed independently by two review authors. Study authors were contacted for confirmation. Main resultsFour trials (with a combined total of 528 adult participants) were included, but almost none of the data from these studies could be aggregated in a meta-analysis.One trial (with 88 participants) compared bromhexine versus placebo. Compared with placebo, high doses of bromhexine with antibiotics eased di iculty in expectoration (mean di erence (MD) -0.53, 95% confidence interval (CI) -0.81 to -0.25 at 16 days); the quality of the evidence was rated as low. A reduction in sputum production was noted with bromhexine (MD -21.5%, 95% CI -38.9 to -4.1 at day 16); again Mucolytics for bronchiectasis (Review)
