Stratification of patients admitted for SARS-CoV2 infection: prognostic scores in the first and second wave of the pandemic.

To test the prognostic performance of different scores, both specifically designed for patients with COVID-19 and generic, in predicting in-hospital mortality and the need for mechanical ventilation (MV). We retrospectively collected clinical data of patients admitted to the Emergency Department of the University Hospital AOU Careggi, Florence, Italy, between February 2020 and January 2021, with a confirmed infection by SARS-CoV2. We calculated the following scores: Sequential Organ Failure Assessment (SOFA) score, CALL score, 4C Mortality score, QUICK score, CURB-65 and MuLBSTA score. The end-points were in-hospital mortality and the need for MV. We included 1208 patients, mean age 60 ± 17 years, 57% male sex. Compared to survivors, non-survivors showed significantly higher values of all the prognostic scores (4C: 13 [10-15] vs 8 [4-10]; CALL: 11 [10-12] vs 9 [7-11]; QUICK: 4 [1-6] vs 0 [0-3]; SOFA: 5 [4-6] vs 4 [4-5]; CURB: 2 [1-3] vs 1 [0-1]; MuLBSTA: 11 [9-13] vs 9 [7-11], all p < 0.001). Discriminative ability evaluated by the Receiver Operating Curve analysis showed the following values of the Area under the Curve: 0.83 for 4C, 0.74 for CALL, 0.70 for QUICK, 0.68 for SOFA, 0.76 for CURB and 0.64 for MuLBSTA. The mortality rate significantly increased in increasing quartiles of 4C and CALL score (respectively, 2, 8, 24 and 54% for the 4C score and 1, 17, 33 and 68% for the CALL score, both p < 0.001). 4C and CALL score allowed an early and good prognostic stratification of patients admitted for pneumonia induced by SARS-CoV2.

Quarantine and Mental Health Challenges for Occupational Medicine: The Case Report of a Nurse Infected With SARS-CoV-2.

This case study draws attention to the psychosocial difficulties that emerged in the context of the coronavirus disease 2019 (COVID-19) outbreak in relation to the remote management of subjects with psychiatric vulnerabilities following exposure to prolonged quarantine. The case involves a 56-year-old hospital nurse, followed by the Occupational Health Department of a major university hospital in central Italy for mood instability in the context of a cyclothymic temperament. She was quarantined for occupationally acquired COVID-19 and remained positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) via swab test for more than 2 months between March and May 2020. In this case study, we discuss the challenges presented by the risk of a prolonged quarantine in a psychologically vulnerable employee, the need for occupational medicine to provide adequate health surveillance of all health care workers during the COVID-19 pandemic, the effectiveness of telepsychiatry, and the difficulties in formulating a proper treatment strategy.

[Role of reaction times in the health surveillance of a group of complex task workers: public transport drivers]. / Ruolo dei tempi di reazione nel protocollo di sorveglianza sanitaria di una categoria di lavoratori adibiti a mansioni complesse: autisti di mezzi pubblici.

In order to assess the relationship between impaired reaction times and other clinical parameters a study was conducted on a population of public transport drivers, 26 impaired reaction times subjects and 114 controls, matched for age, sex and type of job-task, compared for years of employment, blood pressure, audiometric test, mood disorders, sleepiness and body mass index (BMI). Statistical analysis indicates a close trend to relationship of reaction times impairment with BMI and hypertension; these two variables are also correlated. Our results agree with previous literature: despite the fact that mechanisms underlying the relationship between BMI and cognitive impairments remains unknown, subclinical levels of pathophysiologic changes associated with elevated BMI, could account for the observed differences in our samples. Assessing eligibility in occupational medicine, it could be suitable to evaluate some preventive measures evaluating the efficacy of weight loss on cognitive function and on the ability to work safely.
