Introduzione: dalla traduzione intersemiotica all’Atlante lessicografico

Introduzione al 7° numero della rivista dedicato a PAROLA -Scena Le parole della scena: traduzione intersemiotica e interlinguistica dei testi drammaturgici, letterari e di teoria teatrale, il quale trae origine da una serie di discussioni avvenute a margine di convegni e di incontri di lavoro tra studiose/i di teatro, lingua e letteratura russa negli ultimi anni. La questione verteva sul problema della traduzione di termini tecnici, espressioni verbali, parole, concetti estetici e filosofici propri della pratica teatrale in Russia che, applicati in altri contesti culturali, hanno prodotto fraintendimenti e interpretazioni errate, ma anche nuove e stimoltanti interpretazioni

Impact assessment of an education course on vaccinations in a population of pregnant women: A pilot study

Introduction. Although the benefits of vaccinations have been extensively demonstrated, vaccination coverage remains unsatisfactory as result of many people's poor knowledge and negative perception of vaccination. We evaluated the impact of an education course on vaccinations in a population of pregnant women. Methods. A total of 214 pregnant women were invited to participate in this project, which was undertaken at the Obstetrics and Gynaecology Department of Careggi University Hospital in Florence (Italy). Anonymous questionnaires were administered to women before and after the intervention. A descriptive and statistical analysis was carried out in order to compare the responses obtained before and after the intervention. Results. Adherence to the initiative was good (98%): Initially, the respondents were not hostile to vaccinations, though many (43%) were poorly or insufficiently informed. The educational intervention had a positive impact. After the intervention, the number of women who rated their level of knowledge of vaccinations as poor or insufficient had decreased by 30% and the number of "hesitant" respondents had decreased with respect to all aspects of the study, especially the decision to be vaccinated during pregnancy. Conclusions. Hesitancy stems from a lack of accurate information. Healthcare professionals need to improve their communication skills. Appropriate education during pregnancy, when women are more receptive, may have a highly positive impact. These observations need to be considered in the planning of courses to prepare pregnant women for delivery also in other maternal-foetal centres in Italy

Elemental analysis of contemporary dental materials regarding potential beryllium content

Exposure to beryllium (Be) can lead to lung pathologies, such as chronic beryllium disease (CBD). This occupational illness has been more prevalent among dental technicians compared to the non-exposed population. Although most manufacturers state that dental materials are Be-free, this prevalence raises the question of whether the materials are completely devoid of Be-traces. Thus, the objective of the present study was to analyze the elemental composition, with emphasis on Be, of a wide range of commercially available dental materials frequently used by dental laboratories. Samples of 32 different materials were collected and analyzed using inductively coupled plasma-optical emission spectrometry (ICP-OES) and X-ray fluorescence spectroscopy. The results showed that the Be content was below the limit of quantification in all included samples (< 0.00005 mass-%). Therefore, it can be concluded that possible traces of Be were below clinical relevance in dental materials. Exposure of dental technicians to alternative Be sources should be further evaluated

Predicting candidemia in internal medicine departments: are we chasing the Holy Grail?

Candidemia is a challenging clinical condition with high rates of morbidity and mortality.1 Key requirements for its prompt management include early identification and timely initiation of appropriate systemic antifungal therapy, consistently reported as a major determinant of survival. However, the diagnosis of candidemia can be challenging and is often delayed as there are no specific clinical signs, blood cultures have low sensitivity, and detection of fungal blood cultures takes a long time. In addition, there is evidence that a significant percentage of such infections occurs in patients admitted to internal medicine departments. This is not particularly surprising given the advanced age of many inpatients at internal medicine departments and multiple complex comorbidities. Moreover, related therapies and healthcare system contacts often involve the use of central venous catheters and other indwelling devices, potentially entailing high risk of candidemia.2 Therefore, optimization of the diagnostic and therapeutic approach is an important and still unfulfilled need for the management of candidemia in internal medicine department

Gold/Silica biochips: applications to Surface Plasmon Resonance and fluorescence quenching

We report Gold/Silica biochips for low cost biosensor devices. Firstly, the study of biochemical interactions on silica by means of Surface Plasmon Resonance (SPR) is presented. Secondly, Gold/Silica biochips are employed to reduce the strong quenching that occurs when a fluorophore is close to the gold surface. Furthermore, the control of the Silica-like thickness allows optimizing the distance between the metallic surface and the fluorophore in order to enhance the fluorescent signal. These results represent the first steps towards highly sensitive, specific and low cost biosensors based, for example, on Surface Plasmon Coupled Emission (SPCE) techniques

Low in‑hospital mortality rate in patients with COVID‑19 receiving thromboprophylaxis: data from the multicentre observational START‑COVID Register

Abstract COVID-19 infection causes respiratory pathology with severe interstitial pneumonia and extra-pulmonary complications; in particular, it may predispose to thromboembolic disease. The current guidelines recommend the use of thromboprophylaxis in patients with COVID-19, however, the optimal heparin dosage treatment is not well-established. We conducted a multicentre, Italian, retrospective, observational study on COVID-19 patients admitted to ordinary wards, to describe clinical characteristic of patients at admission, bleeding and thrombotic events occurring during hospital stay. The strategies used for thromboprophylaxis and its role on patient outcome were, also, described. 1091 patients hospitalized were included in the START-COVID-19 Register. During hospital stay, 769 (70.7%) patients were treated with antithrombotic drugs: low molecular weight heparin (the great majority enoxaparin), fondaparinux, or unfractioned heparin. These patients were more frequently affected by comorbidities, such as hypertension, atrial fibrillation, previous thromboembolism, neurological disease,and cancer with respect to patients who did not receive thromboprophylaxis. During hospital stay, 1.2% patients had a major bleeding event. All patients were treated with antithrombotic drugs; 5.4%, had venous thromboembolism [30.5% deep vein thrombosis (DVT), 66.1% pulmonary embolism (PE), and 3.4% patients had DVT + PE]. In our cohort the mortality rate was 18.3%. Heparin use was independently associated with survival in patients aged ≥ 59 years at multivariable analysis. We confirmed the high mortality rate of COVID-19 in hospitalized patients in ordinary wards. Treatment with antithrombotic drugs is significantly associated with a reduction of mortality rates especially in patients older than 59 years
