ABSTRACT
Objective: To analyze the diagnostic accuracy of lung ultrasonography (LUS) and high-resolution computed tomography (HRCT), to detect COVID-19. Materials and Methods: This study recruited all patients admitted to the emergency medicine unit, due to a suspected COVID-19 infection, during the first wave of the COVID-19 pandemic. These patients also who underwent a standardized LUS examination and a chest HRCT. The signs detected by both LUS and HRCT were reported, as well as the sensitivity, specificity, positive predictive value, and negative predictive value for LUS and HRCT. Results: This cohort included 159 patients, 101 (63%) were diagnosed with COVID-19. COVID-19 patients showed more often confluent subpleural consolidations and parenchymal consolidations in lower lung regions of LUS. They also had "ground glass” opacities and "crazy paving” on HRCT, while pleural effusion and pulmonary consolidations were more common in non-COVID-19 patients. LUS had a sensitivity of 0.97 (95% CI 0.92–0.99) and a specificity of 0.24 (95% CI 0.07–0.5) for COVID-19 lung infections. HRCT abnormalities resulted in a 0.98 sensitivity (95% CI 0.92–0.99) and 0.1 specificity (95% CI 0.04–0.23) for COVID-19 lung infections. Conclusion: In this cohort, LUS proved to be a noninvasive, diagnostic tool with high sensitivity for lung abnormalities that were likewise detected by HRCT. Furthermore, LUS, despite its lower specificity, has a high sensitivity for COVID-19, which could prove to be as effective as HRCT in excluding a COVID-19 lung infection.
ABSTRACT
Background: COVID-19 outbreak has correlated with the disruption of screening activities, regular follow up visits, and diagnostic assessments. The risk of misdiagnosis and delayed diagnosis has consequently increased during the pandemic. Endometrial cancer is one of the most common gynecological malignancies and it is often detected at an early stage, because it frequently produces symptoms (e.g. abnormal vaginal bleeding). Here, we aim to investigate the impact of COVID-19 outbreak on patterns of presentation and treatment of endometrial cancer patients. Material and methods: This is a retrospective study involving 53 centers in Italy. We evaluated patterns of presentation and treatment of endometrial cancer patients before (i.e. period 1: from 03/01/2019 to 02/29/2020) and during (i.e. period 2: from 01/04/2020 to 3/31/2021) the COVID-19 outbreak. Results: Medical records of 5,117 endometrial cancer patients have been retrieved: 2,688 and 2,429 women treated in period 1 and period 2, respectively. The prevalence of endometrioid International Federation of Obstetrics and Gynecologists (FIGO) grade 1, 2, and 3 was consistent over the study period (p=0.769). However, the prevalence of non-endometrioid endometrial cancer was lower in period 1 than in period 2 (15.7% vs. 17.9%;p=0.015). The characteristics and pattern of different surgical approaches were consistent in the two study periods (p=0.664). Before COVID-19 pandemic, 1,838 (73.2%), 647 (25.7%), and 25 (0.9%) patients had minimally invasive, open and vaginal surgery, respectively. During the COVID-19 pandemic, 1,661 (73.2%), 567 (24.9%), and 41 (1.8%) patients had minimally invasive, open, and vaginal surgery, respectively. Nodal assessment was omitted in 684 (27.3%) and 478 (21%) patients treated in period 1 and 2, respectively (p<0.001). While, the prevalence of patients undergoing sentinel node mapping (with or without backup lymphadenectomy) has increased during the COVID-19 pandemic (46.8% in period 1 vs. 53.1% in period 2;p<0.001). Adjuvant therapy was omitted in 1,269 (50.5%) and 1,019 (44.9%) patients receiving treatment in period 1 and 2, respectively (p<0.001). Adjuvant therapy use has increased during the COVID-19 pandemic (p<0.001). Conclusions: Our data suggest that the COVID-19 pandemic had a significant impact on the characteristics and patterns of care of endometrial cancer patients. These findings highlight the need to implement healthcare services during the pandemic.
