Lung ischemia-reperfusion injury (LIRI) is the life-threatening complication occurring after lung transplantation. Toll-like receptor 4 (TLR4) signaling pathway and hypoxia-inducible factor-1α (HIF-1α) are intimately involved in the development and progression of various inflammatory and hypoxia diseases; however, the relationship of them in LIRI in vivo is still far from clear. ⋯ We identify that the TLR4-HIF-1 loop may be existed in LIRI. Therefore, we suggest that the interaction between them may represent a novel therapeutic target for the development of novel target-based therapies of LIRI.

Review Meta Analysis Comparative Study
Systematic review with meta-analysis of studies comparing intraoperative neuromonitoring of recurrent laryngeal nerves versus visualization alone during thyroidectomy.
The role of intraoperative neuromonitoring (IONM) of the recurrent laryngeal nerve (RLN) during thyroid surgery is still debatable. The aim of this meta-analysis was to evaluate the potential improvement of IONM versus RLN visualization alone (VA) in reducing the incidence of vocal cord palsy. ⋯ The current review with meta-analysis showed no statistically significant difference in the incidence of RLN palsy when using IONM versus VA during thyroidectomy. However, these results must be approached with caution, as they were mainly based on data coming from non-randomized observational studies. Further studies including high-quality multicenter, prospective, randomized trials based on strict criteria of standardization and subsequent clustered meta-analysis are required to verify the outcomes of interest.

We recently reported a grading system for surgical complications. This system proved to have a high sensitivity for recording minor but meaningful complications prolonging hospital stay in patients after colorectal surgery. We aimed to prospectively validate the complication grading system in a general surgery department over 1 year. ⋯ This system of grading surgical complications permits standardized reporting of surgical morbidity according to the severity of impact. Prospective validation of this system supports its use in a general surgery setting as a tool for surgical outcome assessment and quality assurance.

Identification and interference of intraoperative distractions and interruptions in operating rooms.
Intraoperative interruptions potentially interfere with surgical flow, contribute to patient safety risks, and increase stress. This study aimed to observe interruption events in operating rooms (ORs) and to measure surgical team's intraoperative interference from interruptions during surgery. ⋯ The study demonstrates the high level of interference in ORs. Furthermore, it provides a useful measure for intraoperative workflow disruptions and their interference of OR team functioning. OR environments need to be well designed to reduce unnecessary interruptions and distractions, so that surgical teams can manage their surgical tasks efficiently and safely.
