High-resolution anoscopy predictive modeling of anal canal cancer response after definitive chemoradiotherapy in COVID19 era.

PURPOSE: To develop a predictive index model, integrating both clinical and high-resolution anoscopy (HRA) features to further personalize the decision making process in anal canal carcinoma in COVID19 era. METHODS AND MATERIALS: We assess HRA parameters after definitive chemoradiotherapy in patients with anal canal malignant lesions. RESULTS: HRA features could be important to assess the effect of CRT and a risk stratification system should be introduced in clinical practice to better allocate therapeutic interventions. CONCLUSION: To our knowledge this is the first proposal for HRA findings in anal canal cancer after definitive CRT. We believe that a risk score can be useful to estimate the risk of treatment failure (in term of persistence disease and/or recurrence) and its clinical relevance should not to be underestimated.

Deaths from COVID-19 in healthcare workers in Italy—What can we learn?

On April 16, 2020, the Italian National Institute of Health (ISS) reported that 16,991 healthcare workers (HCWs) had tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). On April 17 the latest estimate of medical doctor deaths reached 119, which is 57.8% of total HCW deaths;followed by nurses 16.5% (n = 34), nurse aides 8.3% (n = 17) and dentists 5.8% (n = 12) (Fig. 1).3 The COVID-19–related deaths include 2 nurses who committed suicide due to unsustainable pressure at work.4 No other country has seen the same elevated number of doctor deaths;China, where the epidemic began in December, had fewer.5 General practitioners seem to be the worst hit among all medical specialties, registering 32% deaths (n = 66) (Fig. 1).3 This high rate could reflect their presence in the first line of defense for anyone presenting with the initial symptoms. Nurses and midwives together are the most represented with 43.2% (n = 6,988) of all infected HCWs, followed by doctors 22% (n = 3,574) divided between hospital doctors 19% (n = 3,071), general practitioners 0.8% (n = 130) and other doctors 2.3% (n = 373).1 Data for the healthcare context in which the infections presumably occurred are available for 11,738 HCWs;of these, 70.9% have contracted COVID-19 while serving in hospitals or in emergency care services (ambulance assistance).1 Interestingly, according to the National Federation of Orders of Surgeons and Dentists (FNOMCeO) registry,2 general practitioners accounted for the highest number of HCW deaths (Fig. 1) despite being the least infected group (as reported in the latest ISS analysis).1 Furthermore, according to the National Federation of Professional Nursing Orders (FNOPI), 32% of the nurse deaths by April 16, 2020, initially contracted the virus while on duty in nursing care homes where personal protective equipment (PPE) was mostly lacking, and 50% were working in nonhospital healthcare facilities.4 The sheer intensity of the COVID-19 outbreak in Italy, the recruitment of elderly retired doctors and shortages of PPE, particularly in nonhospital care, might be among relevant factors contributing to the elevated number of fatalities among HCWs in this country. [...]it is essential to carry out another retrospective epidemiological investigation and a prospective study to identify the main risk factors contributing to COVID-19–related deaths in the different HCWs categories in order to produce viable schemes for their protection.

Repercussions of COVID-19-related national lockdown on Emergency Surgery Department: a longitudinal cohort monocentric study.

BACKGROUND: COVID-19 lockdown restrictions in conjunction with the pervasive hospital fear endured by the vast majority of the population played a fundamental role in discouraging access to emergency departments (EDs). We aimed at investigating whether and how the COVID-19 outbreak limited the access to ED and affected urgent surgical activities during and immediately after the 2-month pandemic-related national lockdown. METHODS: Data regarding patients who accessed to the surgical ED were retrospectively collected. Analyzed time-periods included: "pre-COVID-19 era," "COVID-19 era" considered as the period of full national lockdown and "post-COVID-19 era" after easing of lockdown measures. Consecutive emergency surgical procedures and ED admissions before, during and after COVID-19-lockdown were retrieved and analyzed. RESULTS: There was a significant decrease in overall ED admissions and in all-specialty surgical consultations (P<0.01) throughout the outbreak. Once national lockdown was eased, we recorded a subsequent rebound 5-fold rise of emergency surgical procedures compared to COVID-19 group (P=0.011). Time-to-surgery was significantly greater in "COVID-19 era" and "post-COVID-19 era" compared to "pre-COVID-19" group (22.56±4.78, 75.99±15.89 and 16.73±1.76 hours, respectively) (P<0.01). A raised incidence of postoperative complications emerged in the "COVID-19 era" group (37.5%) compared to pre- and post-COVID groups (9.1% and 12.5%, respectively; P<0.001). Mortality rate in the "COVID-19 era" was 31.3% and 7.5% in "post-COVID-19" group (<0.0001). CONCLUSIONS: This study demonstrates the major reduction of emergency surgical procedures and overall, ED admissions caused by COVID-19 pandemic. The raised rate of postoperative complications and mortality might be likely due to the superior severity of surgical conditions observed in the "COVID-19 era" subjects together with a probable deferred pursuit of medical attention.

Does Lung Ultrasound Have a Role in the Clinical Management of Pregnant Women with SARS COV2 Infection?

Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) infection is a major health threat. Pregnancy can lead to an increased susceptibility to viral infections. Although chest computed tomography (CT) represents the gold standard for the diagnosis of SARS-CoV-2 pneumonia, lung ultrasound (LUS) could be a valid alternative in pregnancy. The objectives of this prospective study were to assess the role of LUS in the diagnosis of lung involvement and in helping the physicians in the management of affected patients. Thirty pregnant women with SARS-CoV-2 infection were admitted at the obstetrical ward of our Hospital. Mean age was 31.2 years, mean gestational age 33.8 weeks. Several LUS were performed during hospitalization. The management of the patients was decided according to the LUS score and the clinical conditions. Mean gestational age at delivery was at 37.7 weeks, preterm birth was induced in 20% of cases for a worsening of the clinical conditions. No neonatal complications occurred. In 9 cases with a high LUS score, a chest CT was performed after delivery. CT confirmed the results of LUS, showing a significant positive correlation between the two techniques. LUS seems a safe alternative to CT in pregnancy and may help in the management of these patients.

Is Lung Ultrasound Imaging a Worthwhile Procedure for Severe Acute Respiratory Syndrome Coronavirus 2 Pneumonia Detection?

OBJECTIVES: We compared 2 imaging modalities in patients suspected of having coronavirus disease 2019 (COVID-19) pneumonia. Blinded to the results of real-time reverse transcriptase polymerase chain reaction (rRT-PCR) testing, lung ultrasound (LUS) examinations and chest computed tomography (CT) were performed, and the specific characteristics of these imaging studies were assessed. METHODS: From March 15, 2020, to April 15, 2020, 63 consecutive patients were enrolled in this prospective pilot study. All patients underwent hematochemical tests, LUS examinations, chest CT, and confirmatory rRT-PCR. The diagnostic performance of LUS and chest CT was calculated with rRT-PCR as a reference. The interobserver agreement of radiologists and ultrasound examiners was calculated. Ultrasound and CT features were compared to assess the sensitivity, specificity, positive predictive value, and negative predictive value. Positive and negative likelihood ratios measured the diagnostic accuracy. RESULTS: Nineteen (30%) patients were COVID-19 negative, and 44 (70%) were positive. No differences in demographics and clinical data at presentation were observed among positive and negative patients. Interobserver agreement for CT had a κ value of 0.877, whereas for LUS, it was 0.714. The sensitivity, specificity, positive predictive value, and negative predictive value of chest CT for COVID-19 pneumonia were 93%, 90%, 85%, and 95%, respectively; whereas for LUS, they were 68%, 79%, 88%, and 52%. On receiver operating characteristic curves, area under the curve values were 0.834 (95% confidence interval, 0.711-0.958) and 0.745 (95% confidence interval, 0.606-0.884) for chest CT and LUS. CONCLUSIONS: Lung ultrasound had good reliability compared to chest CT. Therefore, our results indicate that LUS may be used to assess patients suspected of having COVID-19 pneumonia.
