Spinal anesthesia is the most frequently performed anesthesia for cesarean section. The American Society of Anesthesiology recommends using pencil-point spinal needles (SNs) over cutting-bevel SNs to reduce postdural puncture headache (PDPH) in their practice guidelines for obstetric anesthesia. However, there is no meta-analysis addressing the impact of the type of SNs on PDPH among women undergoing Cesarean section surgery. ⋯ Using pencil-point SN appears to be beneficial for preventing PDPH in patients undergoing Cesarean section without increasing any potential adverse effects. Further research addressing the specific gauge of pencil-point SNs, which might further reduce the incidence of PDPH is highly desired.

Review Meta Analysis
Reporting quality of trial abstracts-improved yet suboptimal: A systematic review and meta-analysis.
We conducted a systematic review and meta-analysis of literature to determine if the publication of the Consolidated Standards of Reporting Trials (CONSORT) abstract guideline in 2008 was followed by change in reporting quality of randomized controlled trial (RCT) abstracts. ⋯ The change in reporting quality of RCT abstracts is far from satisfactory, as evidenced by suboptimal post-CONSORT rates and wide CIs of effect sizes for majority of improved items. Mere publication of CONSORT-abstract guideline, without strict endorsement has failed to translate into good quality abstracts.

Although the Manchester Triage System (MTS) was first developed two decades ago, the reliability of the MTS has not been questioned through comparison with a moderating variable; therefore, the aim of this study is to determine the extent of the reliability of MTS using a meta-analytic review. ⋯ The MTS showed an acceptable level of overall reliability in the emergency department, but more development is required to attain almost perfect agreement.

Review Meta Analysis
Magnesium sulfate for postoperative complications in children undergoing tonsillectomies: a systematic review and meta-analysis.
Previous systematical reviews showed that systemic magnesium decreased postoperative pain and reduced morphine use without any reported serious adverse effects in adults. However, studies in children yielded different results. So we conducted a systematic review to evaluate the impact of magnesium sulfate on postoperative complications in children undergoing tonsillectomies. ⋯ Unlike the studies in adults, this review shows there is no statistically significant effect of perioperative use of magnesium in the postoperative pain control in children undergoing tonsillectomies. But it seems has benefits in reducing rescue analgesia, emergence agitation incidence, and laryngospasm.

The Study Within a Trial (SWAT) program exists to 'embed research within research, so as to resolve uncertainties about the different ways of designing, conducting, analyzing, and interpreting evaluations of health and social care' (1). Published in this journal in 2013, a template for the first SWAT protocol outlined an investigation into the effects of site visits by the principal investigator on recruitment in multicentre randomized controlled trials (1). We have now designed a SWAT protocol to extend this question and ask 'does it matter who conducts the site visit?' Our aim is to provide a protocol that trials can implement to address this research question.
