Two-Year Cohort Study of SARS-CoV-2, Verona, Italy, 2020‒2022.

We performed a follow-up of a previously reported SARS-CoV-2 prevalence study (April‒May 2020) in Verona, Italy. Through May 2022, only <1.1% of the city population had never been infected or vaccinated; 8.8% was the officially reported percentage. Limiting protection measures and vaccination boosters to elderly and frail persons seems justified.

Use of Heavy Silicon Oil as Intraocular Tamponade for Inferior Retinal Detachment Complicated by Proliferative Vitreoretinopathy: A Multicentric Experience.

INTRODUCTION: This is a multicentric study on the use of heavy silicon oil (HSO) as an intraocular tamponade for inferior retinal detachment (RD) complicated by proliferative vitreoretinopathy (PVR). METHODS: 139 eyes treated for RD with PVR were included in the study. 10 (7.2%) were affected by primary RD with inferior PVR, while 129 (92.8%) were affected by recurrent RD with inferior PVR. 102 eyes (73.9%) had received a silicon oil (SO) tamponade in a previous intervention prior to receiving HSO. Mean follow-up was 36.5 (standard deviation = 32.3) months. RESULTS: The median interval between HSO injection and removal was 4 months (interquartile range: 3). At the time of HSO removal, the retina was attached in 120 eyes (87.6%), whereas in 17 eyes (12.4%), it had re-detached while the HSO was in situ. 32 eyes (23.2%) showed recurrent RD. A subsequent RD relapse was observed in 14.2% of cases with no RD at the time of HSO removal, and in 88.2% if an RD was present at the time of HSO removal. Advancing age showed a positive association with retinal attachment at the end of follow-up, while the risk of RD relapse at the end of the follow-up showed a significant negative association with HSO tamponade duration and with the use of SO rather than air or gas as post-HSO tamponade materials. Mean best corrected visual acuity was 1.1 logarithm of minimum angle of resolution at all follow-up time points. 56 cases (40.3%) needed treatment for elevated intraocular pressure (IOP), with which no clinically relevant variables were associated during follow-up. CONCLUSION: HSO represents a safe and effective tamponade in cases of inferior RD with PVR. The presence of RD at the time of HSO removal is a negative prognostic factor for the development of a subsequent RD relapse. According to our findings, in cases of RD at the time of HSO removal, a short-term tamponade should definitely be avoided, in favor of SO. Special attention must be paid to the risk of IOP elevation, and patients should be closely monitored.

Poor performance of screening questionnaires for obstructive sleep apnea in male commercial drivers.

PURPOSE: Screening commercial drivers (CDs) for obstructive sleep apnea (OSA) reduces the risk of motor vehicle accidents. We evaluated the accuracy of standard OSA questionnaires in a cohort of CDs. STUDY DESIGN AND METHODS: We enrolled consecutive male CDs at 10 discrete transportation companies during their yearly scheduled occupational health visit. The CDs had their anthropometric measures taken; completed the Berlin, STOP, STOP-BANG, OSAS-TTI, SACS, EUROSAS, and ARES questionnaires; and underwent a home sleep apnea test (HSAT) for the determination of their respiratory events index (REI). We assessed the questionnaires' ability to predict OSA (REI ≥ 5 events/h) and moderate-to-severe OSA (REI ≥ 15 events/h). RESULTS: Among 315 CDs recruited, 243 (77%) completed the study protocol, while 72 subjects were excluded for inadequate HSAT quality. The demographics and clinical data were comparable in both the included and excluded subjects. The included CDs had a median age of 50 years (interquartile range (IQR) 25-70) and a mean body mass index of 27 ± 4 kg/m2. One hundred and seventy-one subjects (71%) had OSA, and 68 (28%) had moderate-to-severe OSA. A receiver operating characteristic curve of the questionnaires were 0.51-0.71 for predicting OSA and 0.51-0.66 for moderate-to-severe OSA. The STOP-BANG questionnaire had an unsatisfactory positive predictive value, while all of the other questionnaires had an inadequate negative predictive value. CONCLUSIONS: Standard OSA questionnaires are not suited for screening among CDs. The use of the HSAT could provide an objective evaluation of for OSA in this special population.

Impact of extra-ampullary duodenal adenocarcinoma subtypes on surgical and oncological outcomes following pancreaticoduodenectomy.

BACKGROUND: There is little information about the relevance of extra-ampullary duodenal adenocarcinoma (EDA) subtypes. The aim of this study was to evaluate the impact of EDA subtypes on surgical and oncological outcomes following pancreatoduodenectomy (PD). METHODS: Consecutive patients undergoing PD for EDA from 2000 to 2019 were analyzed. Results were stratified by pathologic subtype (intestinal versus non-intestinal). Uni-and multivariable analyses were performed using standard statistical methods. RESULTS: The study population consisted of 70 patients, of whom 49 (70%) had an intestinal phenotype. EDA with intestinal phenotype was more frequently proximal to the Ampulla of Vater, while non-intestinal EDA was more frequently found distally (76% vs. 33%, p = 0.002). Patients with intestinal EDA were less likely to experience severe morbidity, with decreased reoperation and unplanned Intensive Care Unit admission rates relative to non-intestinal subtypes (2% vs. 29% p = 0.002, and 2% vs. 19%, p = 0.007, respectively). The median follow-up post-pancreatectomy was 73 months. Intestinal EDA was associated with improved overall and disease-free survival, with 3-year and 5-year survival rates of 71% vs. 29% and 53% vs. 24%, respectively. (p = 0.019 and p = 0.025). CONCLUSION: Intestinal-type EDA, which more often arises from supra-ampullary duodenum, was associated with better postoperative outcomes and improved survival.

Myosteatosis as an independent predictor of short-term mortality in successfully reperfused acute ischemic stroke.

BACKGROUND AND PURPOSE: Poor clinical outcomes are still common in successfully reperfused acute ischemic stroke patients. The aim of our study was to assess the impact of sarcopenia and myosteatosis on neurological outcomes and mortality in successfully reperfused acute ischemic stroke patients. MATERIALS AND METHODS: We included in our retrospective observational study 166 consecutive patients who underwent technically successful mechanical thrombectomy for anterior circulation acute ischemic stroke between Jan 2016 and Dec 2019. ASPECTS and collateral score were assessed on pre-operative CT/CTA. Masseter muscles area and attenuation were measured on CTA images. Clinical and radiological variables were tested in multivariate logistic models to predict the probability of death and, among survivors, of incurring poor outcome. RESULTS: At admission, mean NIHSS was 19 (SD = 6.5), mean body mass index 25.5 (SD = 4.4) kg/m2, and mean ASPECTS 8.0 (SD = 1.9). Of all, 48.2% patients showed good collaterals, 38.5% intermediate collaterals, and 13.3% poor collaterals. Overall, 90 days mRS was ≤2 in 48.2% of the patients, 3-5 in 30.7%, and 6 in 21.1%. At multivariate logistic regression, age (OR = 1.08, p = 0.036), ASPECTS (OR = 0.59, p = 0.013), and masseter muscles attenuation (OR = 0.93, p = 0.010) were independent predictors of mortality, whereas sex (OR = 7.15, p = 0.043), age (OR = 1.05, p = 0.042), body mass index (OR = 1.35, p = 0.013), NIHSS (OR = 1.12, p = 0.012), and ASPECTS (OR = 0.64, p = 0.024) were independent predictors of poor neurological outcome (mRS 3-5). CONCLUSION: Beyond other well-known variables, low masseter attenuation, indicating myosteatosis, represents an independent negative prognostic factor for 90 days mortality in patients successfully reperfused after anterior circulation stroke.

Impact of domiciliary administration of NSAIDs on COVID-19 hospital outcomes: an unCoVer analysis.

Background: Effective domiciliary treatment can be useful in the early phase of COVID-19 to limit disease progression, and pressure on hospitals. There are discrepant data on the use of non-steroidal anti-inflammatory drugs (NSAIDs). Aim of this study is to evaluate whether the clinical outcome of patients who were hospitalized for COVID-19 is influenced by domiciliary treatment with NSAIDs. Secondary objective was to explore the association between other patient characteristics/therapies and outcome. Methods: A large dataset of COVID-19 patients was created in the context of a European Union-funded project (unCoVer). The primary outcome was explored using a study level random effects meta-analysis for binary (multivariate logistic regression models) outcomes adjusted for selected factors, including demographics and other comorbidities. Results: 218 out of 1,144 patients reported use of NSAIDs before admission. No association between NSAIDs use and clinical outcome was found (unadj. OR: 0.96, 95%CI: 0.68-1.38). The model showed an independent upward risk of death with increasing age (OR 1.06; 95% CI 1.05-1.07) and male sex (1.36; 95% CI 1.04-1.76). Conclusion: In our study, the domiciliary use of NSAIDs did not show association with clinical outcome in patients hospitalized with COVID-19. Older ages and male sex were associated to an increased risk of death.
