Measurement and Control of Surgical Smoke to Enhance Surgical Team Safety.
Amid the coronavirus disease 2019 era, concern about the safety of surgical teams related to surgical smoke (SS) is rising. As simple ventilation improvement methods (SVIMs), we replaced 4 of the 8 supply diffusers with a direction-adjustable louver-type, closed 2 of the 4 exhaust grills, and strengthened the sealing of the doorway. ⋯ A similar decrease was observed in the other 5 locations. SVIMs could effectively control SS and the LCPM was also effective in measuring SS in the OR or other spaces of the hospital.

Randomized Controlled TrialIdeal Suggestions for Discharge Training and Telephone Counseling of Patients With Coronary Artery Bypass Graft Surgery: A Randomized Controlled and Experimental Study.
In this context, discharge training and telephone counseling given to patients who underwent coronary artery bypass graft surgery increase the ability of patients to cope with and adapt to their self-care. ⋯ Positive results were achieved in the experimental group which received given discharge training and telephone counseling.

Relative Effectiveness of COVID-19 Vaccination in Healthcare Workers: 3-Dose Versus 2-Dose Vaccination.
The omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is known to have high infectivity and is more likely to evade vaccine immunity. However, booster vaccination is expected to strengthen cross-reactive immunity, thereby increasing the vaccine effectiveness (VE). This study aimed to evaluate the relative VE of the 3-dose (booster) vaccination compared with the 2-dose primary series vaccination in healthcare workers during omicron variant-dominant periods. ⋯ Healthcare workers with positive SARS-CoV-2 test results were classified as positive cases, whereas those with negative results served as controls. Compared with the 2-dose primary series vaccination, booster vaccination with mRNA vaccine showed moderate VE (53.1%). However, in multivariate analysis including the time elapsed after vaccination, the significant VE disappeared, reflecting the impact of recent vaccination rather than the third dose itself.

Incidence and Risk Factors for Totally Implantable Venous Access Device Infections in Pediatric Patients With Cancer: A Study of 25,954 Device-Days.
Totally implantable venous access devices (TIVADs) are frequently used in pediatric patients with cancer owing to their multiple benefits. Despite occasional infections with TIVADs, knowledge of the incidence and risk factors is limited. ⋯ TIVAD infection may be related to thrombocytopenia at the time of device insertion. Further studies are needed to identify preventive factors against TIVAD infections in children with cancer.
