Stress, Burnout, and Resilience among Healthcare Workers during the COVID-19 Emergency: The Role of Defense Mechanisms.

The experience of working on the frontlines of the COVID-19 healthcare crisis has presented a cumulative traumatic experience that affects healthcare professionals' well-being. Psychological resources such as resilience and adaptive defense mechanisms are essential in protecting individuals from severe stress and burnout. During September 2020, 233 healthcare workers responded to an online survey to test the impact of demographic variables, COVID-19 exposure, and psychological resources in determining stress and burnout during the COVID-19 emergency.

Effectiveness of the ECG method in the correct positioning of PICC type central venous catheters in patients with atrial fibrillation.

The peripherally inserted central catheters (PICCs) are third generation silicone or polyurethane catheters, used as venous accesses for long- and medium-term care, and recommended in therapies that require venous access for more than six days. Current implantation methods recommend the radiological method, using standard chest RX in antero-posterior projection, as a method of assessing the correct positioning of the catheter tip. The observational study evaluated the effectiveness in terms of reliability of the intracavitary tip location system (ITLS) method, better known as the ECG method, for the correct positioning of the catheter tip in patients with atrial fibrillation (AFIB); the method exploits the recording of the electrical potential produced by the f waves, expression of the fibrillation of the atrium typical in patients with this disease, the measurement is based on the calculation of the peak-to-peak value of the f waves.
