A Novel Scale to Assess Humidification during Noninvasive Ventilation: A Prospective Observational Study.

Objective: To develop a novel scale to assess humidification during noninvasive ventilation (NIV).

Methods: This study was performed in an ICU of a teaching hospital. Three ICU practitioners with more than 10 years of clinical experience developed an oral humidification scale with a range of 1-4 points.

Use of high-flow nasal cannula and noninvasive ventilation in patients with COVID-19: A multicenter observational study.

Background: The use of high-flow nasal cannula (HFNC) and noninvasive ventilation (NIV) in patients with COVID-19 is debated.

Methods: This study was performed in four hospitals of China from January to March 2020. We retrospectively enrolled 23 and 13 COVID-19 patients who used HFNC and NIV as first-line therapy, respectively.

Risk factors for venous thrombosis associated with peripherally inserted central venous catheters.

To evaluate the risk factors associated with an increased risk of symptomatic peripherally inserted central venous catheter (PICC)-related venous thrombosis. Retrospective analyses identified 2313 patients who received PICCs from 1 January 2012 to 31 December 2013. All 11 patients with symptomatic PICC-related venous thrombosis (thrombosis group) and 148 who did not have thromboses (non-thrombosis group) were selected randomly.
