Validation of the North America expert consensus statement on reporting CT findings for COVID-19 in individuals with lung cancer.

The aim of our study was to validate the use of the standardized Radiological Society of North America (RSNA) reporting system in individuals with known lung cancer who presented to the emergency department with suspected COVID-19. We included patients aged 18 years or older from the Cancer Institute of the State of São Paulo (ICESP) with a confirmed diagnosis of lung cancer, admitted to the emergency department and undergoing chest computed tomography (CT) for suspicion of COVID-19. Comparison between SARS-CoV2 RT-PCR across RSNA categories was performed in all patients and further stratified by diagnosis of lung cancer progression. Among 58 individuals included in the analysis (65±9 years, 43% men), 20 had positive RT-PCR. Less than a half (43%) had no new lung findings in the CT. Positive RT-PCR was present in 75% of those with typical findings according to RSNA and in only 9% when these findings were classified as atypical or negative (P<0.001). Diagnostic accuracy was even higher when stratified by the presence or absence of progressive disease (PD). Extent of pulmonary inflammatory changes was strongly associated with higher mortality, reaching a lethality of 83% in patients with >25% of lung involvement and 100% when there was >50% of lung involvement. The lung involvement score was also highly predictive of prognosis in this population as was reported for non-lung cancer individuals. Collectively, our results demonstrated that diagnostic and prognostic values of chest CT findings in COVID-19 are robust to the presence of lung abnormalities related to lung cancer.

Clinical presentation and in-hospital prognosis of lung cancer patients presenting with suspected and confirmed COVID-19.

We sought to compare the clinical presentation and prognosis of patients with lung cancer and confirmed COVID-19 infection to those with negative RT-PCR SARS-CoV-2 results. We included patients with confirmed lung cancer and suspected COVID-19 who presented to the emergency department. The primary outcome was in-hospital mortality and secondary outcomes included admission to intensive care unit (ICU) or mechanical ventilation. We analyzed the characteristics according to RT-PCR results and primary outcome. We constructed a logistic regression for each RT-PCR result group to find potential predictors of the primary outcome. Among 110 individuals with confirmed lung cancer (65±9 years, 51% male), 38 patients had positive RT-PCR and 72 patients had negative RT-PCR. There was no difference between groups for any clinical characteristic or comorbidities though individuals with confirmed COVID-19 had higher functionality in the ECOG scale. Leucocytes and lymphocytes were lower in individuals with positive tests. The primary outcome occurred in 58 (53%) individuals, 37 (34%) were admitted to the ICU, and 29 (26%) required mechanical ventilation. Although mortality was similar between the two groups, individuals with confirmed COVID-19 were significantly more likely to be admitted to the ICU or receive mechanical ventilation. Only lower lymphocytes and higher CRP were significantly associated with higher mortality. The clinical presentation of COVID-19 in lung cancer is not sufficient to identify higher or lower probability groups among symptomatic individuals, the overall mortality is high irrespective of RT-PCR results, and lymphopenia on admission was associated with the diagnosis and prognosis for COVID-19.

[Freedom from smoking for health care workers. A project from Trieste]. / Operatori della sanità liberi dal fumo. Attivazione di un progetto in Provincia di Trieste.

A tree years interventional study to modify smoking habits in health workers in Trieste province was planed in the collaboration of occupational health unit and Tobacco's Dependence Study Center. The aim of this paper is refer about preliminary data of the project started in 2007 regarding smoking habits in health workers of the Azienda per i Servizi Sanitari n.1 "Triestina" (ASS1) and the Azienda Ospedaliera Universitaria Ospedali Riuniti di Trieste (AOUTS). The project consist of several actions. i) information about risks and opportunities of project; ii) pursuance of the law 51 L 3/2003; iii) Occupational Health Unit and Tobacco's Dependence Study Center collaboration; iv) follow-up of the subjects that choose the disaccustom program. During occupational medical surveillance we collected the data related to 492 workers, 37% of the cases were smokers (180). The results of test of dependence to smoke (test di Fagestrom) showed an high dependence in 19% and an high motivation to stop smoke (test di Richmond) in 39% of the smokers. More than fifty percent of this subjects gave their adhesion to the disaccustom program.
