Review Meta AnalysisEarly versus delayed umbilical cord clamping in preterm infants.
Optimal timing for clamping of the umbilical cord at birth is unclear. Early clamping allows for immediate resuscitation of the newborn. Delaying clamping may facilitate transfusion of blood between the placenta and the baby. ⋯ Delaying cord clamping by 30 to 120 seconds, rather than early clamping, seems to be associated with less need for transfusion and less intraventricular haemorrhage. There are no clear differences in other outcomes.

Discharge planning is a routine feature of health systems in many countries. The aim is to reduce hospital length of stay and unplanned readmission to hospital, and improve the co ordination of services following discharge from hospital thereby bridging the gap between hospital and place of discharge. Sometimes discharge planning is offered as part of an integrated package of care, which may cover both the hospital and community. The focus of this review is discharge planning that occurs while a patient is in hospital; we exclude studies that evaluate discharge planning with follow up care. ⋯ The impact of discharge planning on readmission rates, hospital length of stay, health outcomes and cost is uncertain. This reflects a lack of power as the degree to which we could pool data was restricted by the different reported measures of outcome. It is possible that even a small reduction in length of stay, or readmission rate, could have an impact on the timeliness of subsequent admissions in a system where there is an shortage of acute hospital beds.

Sore throat is a very common reason for people to seek medical care. It is a disease that remits spontaneously, that is, 'cure' is not dependent on treatment. Nonetheless primary care doctors commonly prescribe antibiotics for sore throat and other upper respiratory tract infections. ⋯ Antibiotics confer relative benefits in the treatment of sore throat. However, the absolute benefits are modest. Protecting sore throat sufferers against suppurative and non-suppurative complications in modern Western society can be achieved only by treating with antibiotics many who will derive no benefit. In emerging economies where rates of for example acute rheumatic fever are high, the number needed to treat may be much lower. Antibiotics shorten the duration of symptoms by a mean of one day about half way through the illness (the time of maximal effect), and by about sixteen hours overall.

Review Meta AnalysisInhaled fluticasone versus inhaled beclomethasone or inhaled budesonide for chronic asthma.
Beclomethasone dipropionate (BDP) and budesonide (BUD) are commonly prescribed inhaled corticosteroids for the treatment of asthma, Fluticasone propionate (FP) is newer agent with greater potency in in-vitro assays. ⋯ Fluticasone given at half the daily dose of beclomethasone or budesonide leads to small improvements in measures of airway calibre, but it appears to have a higher risk of causing side-effects when given at the same daily dose.

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.
