A recent systematic review and meta-analysis conducted by researchers at the University of Adelaide examined the effectiveness of fibrin sealants in head and neck surgery. The review included 14 studies with a total of 904 patients and found that the use of fibrin sealants was associated with a reduction in postoperative wound complications, shorter drain removal times, decreased drain output, and shorter hospital stays compared to controls. However, the researchers noted methodological weaknesses and clinical heterogeneity in the studies, which limit the findings. Further research is needed to improve the quality of studies and explore the cost-effectiveness of fibrin sealant use in surgery. [Extracted from the article]

A recent study conducted by researchers at the University of Rochester in New York examined the suitability of minced cartilage fragments for immediate autograft reimplantation in the treatment of osteochondral lesions of the talus (OLT). The study involved 31 patients who underwent primary arthroscopic surgery for their OLT, and their loose or damaged cartilage fragments were removed and analyzed in the laboratory. The researchers found that a large number of viable cells could be obtained from the harvested OLT fragments, and these cells could be reimplanted into the chondral defect during a single-stage surgery. Further clinical studies are needed to determine the impact of these live autologous cells on the quality of repair tissue and clinical outcomes. [Extracted from the article]

A recent study conducted by researchers at McMaster University explored the impact of endothelium on the anticoagulant activity of a covalent antithrombin-heparin complex (ATH).

They also tested the synthetic sulfoglycolipid Tol-51 and found that it did not negatively affect the behavior of the aldynoglia cells. This combination of aldynoglia, alkaline fibrin, and Tol-51 could potentially be used as a therapeutic strategy for tSCI repair. [Extracted from the article]

A study conducted at Taichung Tzu Chi Hospital in Taiwan compared the safety and effectiveness of two techniques for transoral endoscopic thyroidectomy vestibular approach (TOETVA) surgery. The study divided patients into two groups: one group received TOETVA with drainage, and the other group received TOETVA with fibrin sealant (Tisseel). The study found that there were no significant differences in patient demographics, tumor size, blood loss, and hospitalization days between the two groups. Additionally, the incidence of complications and postoperative pain was similar in both groups. However, the operative time for TOETVA with Tisseel was significantly shorter than for TOETVA with drainage. The researchers concluded that TOETVA with Tisseel is a safe alternative to TOETVA with drainage, with the added benefit of a shorter operative time. [Extracted from the article]
