COVID-19 hospital outbreaks: Protecting healthcare workers to protect frail patients. An Italian observational cohort study.

Objectives: To determine the prevalence of SARS-CoV-2 infection among exposed healthcare workers (HCWs) after preventive protocol implementation.

Methods: A total of 5750 HCWs were included in the study. Those in contact with COVID-19 patients were allocated into a high-risk or a low-risk group based on contact type (PPE- or non-PPE-protected); high-risk workers underwent nasopharyngeal swab tests, while among low-risk workers, swab tests were carried out only for symptomatic workers (active surveillance).

Background: Pathologic myopia is often associated with many complications, e.g. retinopathy, vitreous detachment and glaucoma.

Collection and evaluation of incidents in a radiotherapy department : a reactive risk analysis.

Purpose: to report on the use of an internal system for incident reporting.

Patients And Methods: from October 2001 until June 2009, data on incidents were collected in the radiotherapy department (RT) by means of an incident reporting worksheet. The risk analysis was based on the US Navy method of mishap cause investigation, the Human Factors Analysis and Classification System (HFACS).

Incidents analysis in radiation therapy: application of the human factors analysis and classification system.

The purpose of this investigation was to analyse incidents discovered in our radiation therapy department by means of human factor analysis and classification system (HFAC S). We adapted the original framework of the HFAC S and apply it to the analysis of incidents discovered in our radiotherapy department during a five-year period. Results showed that recurrent causal factors of incidents were attention failures and distracted/overconfidence behaviour as well as loss of situational awareness and mental fatigue.

Three-dimensional conformal radiotherapy for locally advanced (Stage II and worse) head-and-neck cancer: dosimetric and clinical evaluation.

Purpose: To evaluate the dosimetric parameters of three-dimensional conformal radiotherapy (3D-CRT) in locally advanced head-and-neck tumors (Stage II and above) and the effects on xerostomia.

Methods And Materials: A total of 49 patients with histologically proven squamous cell cancer of the head and neck were consecutively treated with 3D-CRT using a one-point setup technique; 17 had larynx cancer, 12 oropharynx, 12 oral cavity, and 6 nasopharynx cancer; 2 had other sites of cancer. Of the 49 patients, 41 received postoperative RT and 8 definitive treatment.
