Background: To conduct a meta-analysis to compare the safety and efficacy of transoral endoscopic thyroidectomy vestibular approach (TOETVA) with conventional open thyroidectomy (COT). Methods: MEDLINE, EMBASE, Science Citation Index Expanded, and the Cochrane Central Register of Controlled Trials in the Cochrane Library from January 2007 to March 2020 were searched to identify studies comparing TOETVA and COT. Results: Six eligible nonrandomized studies involving 1151 patients were included. Meta-analysis results revealed that TOETVA group had a significantly longer operative time (weighted mean difference [WMD], 66.09; 95% confidence interval [CI], 35.22-96.96; P < .0001) and larger amount of drainage (WMD, 98; 95% CI, 20.14-175.86; P = .01). There were no significant differences in terms of postoperative outcomes. Conclusion: TOETVA appears to be as feasible and safe as the COT for the treatment of patients with benign thyroid nodules and selected differential thyroid carcinomas.

Ferroptosis, a recently discovered regulated cell death modality, is characterised by iron-dependent accumulation of lipid hydroperoxides, which can reach lethal levels but can be specifically reversed by ferroptosis inhibitors. Osteoarthritis (OA), the most common degenerative joint disease, is characterised by a complex pathogenesis involving mechanical overload, increased inflammatory mediator levels, metabolic alterations, and cell senescence and death. Since iron accumulation and oxidative stress are the universal pathological features of OA, the role played by ferroptosis in OA has been extensively explored. Increasing evidence has shown that iron dyshomeostasis and lipid peroxidation are closely associated with OA pathogenesis. Therefore, in this review, we summarize recent evidence by focusing on ferroptotic mechanisms and the role played by ferroptosis in OA pathogenesis from the perspectives of clinical findings, animal models, and cell research. By summarizing recent research advances that characterize the relationship between ferroptosis and OA, we highlight avenues for further research and potential therapeutic targets.
