Clinical characteristics and outcomes of vaccinated patients hospitalised with SARS-CoV-2 breakthrough infection: Multi-IPV, a multicentre study in Northern Italy

Background: Despite the well-known efficacy of anti-COVID-19 vaccines in preventing morbidity and mortality, several vaccinated individuals are diagnosed with SARS-CoV-2 breakthrough infection, which might require hospitalisation. This multicentre, observational, and retrospective study aimed to investigate the clinical characteristics and outcomes of vaccinated vs. non -vaccinated patients, both hospitalised with SARS-CoV-2 infection in 3 major hospitals in Northern Italy. Methods: Data collection was retrospective, and paper and electronic medical records of adult patients with a diagnosed SARS-CoV-2 infection were pseudo-anonymised and analysed. Vaccinated and non -vaccinated individuals were manually paired, using a predetermined matching criterion (similar age, gender, and date of hospitalisation). Demographic, clinical, treatment, and outcome data were compared between groups differing by vaccination status using Pearson's Chi-square and Mann -Whitney tests. Moreover, multiple logistic regression analyses were performed to assess the impact of vaccination status on ICU admission or intra-hospital mortality. Results: Data from 360 patients were collected. Vaccinated patients presented with a higher prevalence of relevant comorbidities, like kidney replacement therapy or haematological malignancy, despite a milder clinical presentation at the first evaluation. Non -vaccinated patients required intensive care more often than their vaccinated counterparts (8.8% vs. 1.7%, p = 0.002). Contrariwise, no difference in intra-hospital mortality was observed between the two groups (19% vs. 20%, p = 0.853). These results were confirmed by multivariable logistic regressions, which showed that vaccination was significantly associated with decreased risk of ICU admission (aOR=0.172, 95%CI: 0.039-0.542, p = 0.007), but not of intra-hospital mortality (aOR=0.996, 95%CI: 0.582-1.703, p = 0.987). Conclusions: This study provides real -world data on vaccinated patients hospitalised with COVID-19 in Northern Italy. Our results suggest that COVID-19 vaccination has a protective role in individuals with higher risk profiles, especially regarding the need for ICU admission. These findings contribute to our understanding of SARS-CoV-2 infection outcomes among vaccinated individuals and emphasise the importance of vaccination in preventing severe disease, particularly in those countries with lower first -booster uptake rates

Understanding CEAP Classification: Insights from an Italian Survey on Corona Phlebectatica and Recurrent Active Venous Ulcers by Vascular Specialists

Background and Objectives: The clinical relevance of “corona phlebectatica” and the management of risk factors for recurrence of venous ulcers in patients with chronic venous disease may be variable based on vascular specialists in different geographical areas of Italy. The aim of the present survey is to evaluate the management of patients with chronic venous disease by vascular specialists in different areas of the national territory. In particular, this involves ascertaining the clinical/prognostic relevance attributed to the presence of the “corona phlebectatica” as well as to the management of risk factors related to recurrence of venous ulcers. Materials and Methods: The web-based survey aimed at vascular medicine specialists with particular interest in venous disease. A questionnaire was developed, based on 12 questions, in relation to clinical assessment, risk factor management, and therapy in patients with chronic venous disease. Results: Almost all of the specialists involved actively participated in the survey, declaring that they personally manage chronic venous disease overall. There was a strong agreement in the prognostic consideration attributed to the presence of “corona phlebectatica” and to the management of risk factors for venous ulcer recurrence, regardless of the different geographical areas of interest. Conclusions: Accordingly with the results of this self-assessment survey, the skills and experience of the specialists involved appear to be of a good standard, both in the clinical evaluation and in the management of the progression of chronic venous disease. However, the need to reach more cultural insights into the correlations between chronic venous disease and risk factors correlated with disease progression emerges. Moreover, there was the need for a greater and tighter overall clinical control of a patient with chronic venous disease, also in relation to the presence of comorbidities

Ultrasound-Assisted and Ultrasound-Guided Thoracentesis: An Educational Review

Thoracentesis is one of the most important invasive procedures in the clinical setting. Particularly, thoracentesis can be relevant in the evaluation of a new diagnosed pleural effusion, thus allowing for the collection of pleural fluid so that laboratory tests essential to establish a diagnosis can be performed. Furthermore, thoracentesis is a maneuver that can have therapeutic and palliative purposes. Historically, the procedure was performed based on a physical examination. In recent years, the role of ultrasound has been established as a valuable tool for assistance and guidance in the thoracentesis procedure. The use of ultrasound increases success rates and significantly reduces complications. The aim of this educational review is to provide a detailed and sequential examination of the procedure, focusing on the two main modalities, the ultrasound-assisted and ultrasound-guided form

Different peripheral expression patterns of the nicotinic acetylcholine receptor in dementia with Lewy bodies and Alzheimer’s disease

Abstract Background The diffuse distribution of nicotinic cholinergic receptors (nAChRs) in both brain and peripheral immune cells points out their involvement in several pathological conditions. Indeed, the deregulated function of the nAChR was previously correlated with cognitive decline and neuropsychiatric symptoms in Alzheimer’s disease (AD) and Dementia with Lewy bodies (DLB). The evaluation in peripheral immune cells of nAChR subtypes, which could reflect their expression in brain regions, is a prominent investigation area. Objectives This study aims to evaluate the expression levels of both the nAChR subunits and the main known inflammatory cytokines in peripheral blood mononuclear cells (PBMCs) of patients with DLB and AD to better characterize their involvement in these two diseases. Results Higher gene expression levels of TNFα, IL6 and IL1β were observed in DLB and AD patients in comparison with healthy controls (HC). In our cohort, a reduction of nAChRα4, nAChRβ2 and nAChRβ4 was detected in both DLB and AD with respect to HC. Considering nAChR gene expressions in DLB and AD, significant differences were observed for nAChRα3, nAChRα4, nAChRβ2 and nAChRβ4 between the two groups. Moreover, the acetylcholine esterase (AChE) gene expression was significantly higher in DLB than in AD. Correlation analysis points out the relation between different nAChR subtype expressions in DLB (nAChRβ2 vs nAChRα3; nAChRα4 vs nAChRα3) and AD (nAChRα4 vs nAChRα3; nAChRα4 vs nAChRβ4; nAChRα7 vs nAChRα3; nAChRα7 vs nAChRα4). Conclusions Different gene expressions of both pro-inflammatory cytokines and nAChR subtypes may represent a peripheral link between inflammation and neurodegeneration. Inflammatory cytokines and different nAChRs should be valid and accurate peripheral markers for the clinical diagnosis of DLB and AD. However, although nAChRs show a great biological role in the regulation of inflammation, no significant correlation was detected between nAChR subtypes and the examined cytokines in our cohort of patients

The impact of COVID-19 pandemic on well-being of Italian physicians: a report from the Italian Society of Internal Medicine (SIMI) national survey

Over the past few years, COVID-19 pandemic has imposed a high toll worldwide, with a high burden of morbidity and mortality. Healthcare practitioners (HCPs) have been in the frontline since the beginning of the outbreak, and the high level of stress have affected their physical and mental status, as well as their relationships. We aimed at exploring the self-reported changes in comprehensive well-being in a cohort of Italian physicians. An online-based survey was administered to the members of the Italian Society of Internal Medicine (SIMI) between March and June 2021. The survey was based on 32 multiple-choice questions exploring self-reported physical and mental well-being, as well as changes in workloads, work-related feelings and physicians' relationship with patients, colleagues and families. 228 physicians (mean age: 35.7 +/- 9.8 years) participated in the survey; 120 (52.6%) were residents, 196 (86.0%) worked in COVID-19 units and 65 (28.5%) had COVID-19 during the pandemic. A significant proportion of respondents reported to have experience onset or worsening of physical and mental symptoms, with insomnia/sleep disorders (58.3%) and mood swings (47.8%) being the most common, respectively. The burden of physical and mental consequences was broadly higher among residents compared to specialists, with the former reporting more frequently an increase in the number of worked hours (p = 0.020) and being more frequently infected with COVID-19 (35.0% vs. 21.3, p = 0.032). Moreover, familiar and doctor-patient relationships were also considerably affected. Physicians have been suffering a wide spectrum of physical, mental and relational consequences during COVID-19 pandemic, with youngest doctors being more likely to present several physical and mental health symptoms. Further studies are needed to evaluate long-term consequences of COVID-19 pandemic on the well-being of HCPs, and potential preventive strategies
