Randomized Controlled Trial
Bronchial blocker versus left double-lumen endotracheal tube in video-assisted thoracoscopic surgery: a randomized-controlled trial examining time and quality of lung deflation.
Double-lumen endotracheal tubes (DL-ETT) and bronchial blockers (BB) have both been used for lung isolation in video-assisted thoracic surgery (VATS). Though not well studied, it is widely thought that a DL-ETT provides faster and better quality lung collapse. The aim of this study was to compare a BB technique vs a left-sided DL-ETT strategy with regard to the time and quality of lung collapse during one-lung ventilation (OLV) for elective VATS. ⋯ The time and quality of lung collapse during OLV for VATS was significantly better when using a BB than when using a left-sided DL-ETT. Surgeons could not reliably determine which device was being used based on the time and quality of lung collapse. This trial was registered at ClinicalTrials.gov number, NCT01615263.

Comparative Study
Safety and comparative costs of preoperative assessments for cataract surgery: traditional mandatory assessment versus a novel graded assessment system.
We conducted this study to evaluate the safety and costs of traditional mandatory preoperative assessment for cataract surgery patients compared with a novel graded preoperative assessment system. ⋯ The graded system resulted in no major complications and a low rate of minor complications. The information obtained from the mandatory assessment is unlikely to prevent complications. Additionally, the cost effectiveness of the mandatory system was poor. This novel graded preoperative assessment system for cataract surgery patients can save time and resources by eliminating unnecessary patient visits.

Mentorship has been shown to improve career satisfaction, research productivity, and retention of academic physicians. There is a current lack of studies investigating factors that either promote or hinder effective mentoring relationships through the perspectives of both faculty and residents. The aim of this study was to ascertain these factors and subsequently to provide guidance on designing residency mentorship programs. ⋯ We identified three key factors that facilitate or hinder mentorship relationships and proposed solutions for designing effective mentorship programs for postgraduate training programs.

Amniotic fluid embolism is always a severe complication and generally occurs during labour or immediately after childbirth. ⋯ Amniotic fluid embolism is a rare and difficult diagnosis, especially in unconventional settings, yet it can be facilitated by screening for amniotic markers and tryptase.
