NCT04685681
The primary aim of this study is to examine whether lower-risk activities displace participation in higher-risk behaviors during COVID-19. Investigators will test this aim by promoting specific activities that are expected to be low-risk when it comes to COVID-19 transmission (e.g., participating in a hiking challenge) and assessing impacts on participants' activity choices. Investigators also aim to describe adults' activity participation during COVID-19 generally and to examine secondary outcomes, including reported stress and sleep.
NCT05474261
Bleeding after total thyroidectomy remains a rare event that affects early postoperative morbidity, occurring in 0.3% up to 4.2% of cases. Intraoperative bleeding is an unpleasant complication, and it is often easily manageable though postoperative bleeding may represent a life-threatening condition for the patient. Between January 2019 to February 2022 , 250 consecutive patients were listed for thyroidectomy. The Investigators selected 178 patients and divided them in two groups based on the execution of the Valsalva Manoeuvre. The purpose of the investigator is to clarify whether the routine intraoperative execution of a Valsalva manoeuvre (VM) may affect the detection of bleeding that would otherwise remain occult and therefore may manifest in the postoperative period.
