Primary Cardiac Angiosarcoma in a Young Woman

A 30-year-old woman was admitted to our hospital with severe shortness of breath. A transthoracic echocardiogram showed moderate pericardial effusion with a lesion in the right atrium, confirmed by chest CT scan and cardiac RMN. Pleural and middle lobe involvement occurred within one month. Middle lobe biopsy was performed and pathological examination confirmed the diagnosis of metastatic angiosarcoma. After two months, because of recurrent pleural effusions, chemical pleurodesis was performed. Chemotherapy was started but the patient died four months after the diagnosis. This case highlights the misdiagnosis at initial clinical presentation, available diagnostic approaches and therapeutic options for cardiac angiosarcoma

A chemical survey of exoplanets with ARIEL

Thousands of exoplanets have now been discovered with a huge range of masses, sizes and orbits: from rocky Earth-like planets to large gas giants grazing the surface of their host star. However, the essential nature of these exoplanets remains largely mysterious: there is no known, discernible pattern linking the presence, size, or orbital parameters of a planet to the nature of its parent star. We have little idea whether the chemistry of a planet is linked to its formation environment, or whether the type of host star drives the physics and chemistry of the planet’s birth, and evolution. ARIEL was conceived to observe a large number (~1000) of transiting planets for statistical understanding, including gas giants, Neptunes, super-Earths and Earth-size planets around a range of host star types using transit spectroscopy in the 1.25–7.8 μm spectral range and multiple narrow-band photometry in the optical. ARIEL will focus on warm and hot planets to take advantage of their well-mixed atmospheres which should show minimal condensation and sequestration of high-Z materials compared to their colder Solar System siblings. Said warm and hot atmospheres are expected to be more representative of the planetary bulk composition. Observations of these warm/hot exoplanets, and in particular of their elemental composition (especially C, O, N, S, Si), will allow the understanding of the early stages of planetary and atmospheric formation during the nebular phase and the following few million years. ARIEL will thus provide a representative picture of the chemical nature of the exoplanets and relate this directly to the type and chemical environment of the host star. ARIEL is designed as a dedicated survey mission for combined-light spectroscopy, capable of observing a large and well-defined planet sample within its 4-year mission lifetime. Transit, eclipse and phase-curve spectroscopy methods, whereby the signal from the star and planet are differentiated using knowledge of the planetary ephemerides, allow us to measure atmospheric signals from the planet at levels of 10–100 part per million (ppm) relative to the star and, given the bright nature of targets, also allows more sophisticated techniques, such as eclipse mapping, to give a deeper insight into the nature of the atmosphere. These types of observations require a stable payload and satellite platform with broad, instantaneous wavelength coverage to detect many molecular species, probe the thermal structure, identify clouds and monitor the stellar activity. The wavelength range proposed covers all the expected major atmospheric gases from e.g. H2O, CO2, CH4 NH3, HCN, H2S through to the more exotic metallic compounds, such as TiO, VO, and condensed species. Simulations of ARIEL performance in conducting exoplanet surveys have been performed – using conservative estimates of mission performance and a full model of all significant noise sources in the measurement – using a list of potential ARIEL targets that incorporates the latest available exoplanet statistics. The conclusion at the end of the Phase A study, is that ARIEL – in line with the stated mission objectives – will be able to observe about 1000 exoplanets depending on the details of the adopted survey strategy, thus confirming the feasibility of the main science objectives.Peer reviewedFinal Published versio

Covid-19 and the role of smoking: the protocol of the multicentric prospective study COSMO-IT (COvid19 and SMOking in ITaly).

The emergency caused by Covid-19 pandemic raised interest in studying lifestyles and comorbidities as important determinants of poor Covid-19 prognosis. Data on tobacco smoking, alcohol consumption and obesity are still limited, while no data are available on the role of e-cigarettes and heated tobacco products (HTP). To clarify the role of tobacco smoking and other lifestyle habits on COVID-19 severity and progression, we designed a longitudinal observational study titled COvid19 and SMOking in ITaly (COSMO-IT). About 30 Italian hospitals in North, Centre and South of Italy joined the study. Its main aims are: 1) to quantify the role of tobacco smoking and smoking cessation on the severity and progression of COVID-19 in hospitalized patients; 2) to compare smoking prevalence and severity of the disease in relation to smoking in hospitalized COVID-19 patients versus patients treated at home; 3) to quantify the association between other lifestyle factors, such as e-cigarette and HTP use, alcohol and obesity and the risk of unfavourable COVID-19 outcomes. Socio-demographic, lifestyle and medical history information will be gathered for around 3000 hospitalized and 700-1000 home-isolated, laboratory-confirmed, COVID-19 patients. Given the current absence of a vaccine against SARS-COV-2 and the lack of a specific treatment for -COVID-19, prevention strategies are of extreme importance. This project, designed to highly contribute to the international scientific debate on the role of avoidable lifestyle habits on COVID-19 severity, will provide valuable epidemiological data in order to support important recommendations to prevent COVID-19 incidence, progression and mortality

Functional benefit of smoking cessation in severe COPD patients undergoing bronchial valve implantation

Introduction: Tobacco smoke is the leading cause of chronic obstructive pulmonary disease. The aim of this study is to highlight the effectiveness of smoking cessation along with bronchial valve implantation in subjects with severe COPD. Methods: A sample of 25 patients, current smokers, affected by severe COPD and heterogeneous emphysema who quit smoking were compared with a group of 15 patients who did not quit smoking. Measurements and main results Patients performed plethysmography, 6 minute walking test (WT), haemogasanalysis, exhaled CO test (eCO), COPD assessment test (CAT) together with the mMRC test. A clearer improvement of examined parameters was registered in the group of patients who quit smoking by varenicline and counselling. In particular, we observed a significant increase of FEV1 by 350 ml in the abstainers group compared with 100 ml increase in the non-abstainers(p < .05) group. We noticed that the RV% decreased by 30% compared with the 10% in the non-abstainers(p < .001). The CAT value decreased by 20 compared with 10 in current smokers(p < .001) as well as the mMRC score (p < .001) was more improved in abstainers. The total resistances were reduced by 30% versus 10% (p < .01)and notably there was a higher improvement of walking test (30 m versus 5) (p < .001). The eCO was clearly reduced in abstainers, 14 versus 8 (p < .002),. PaO2 increased by 4 mmHg versus 1(p < .0001). Conclusions: Smoking cessation treatment by varenicline strengthens the effects of bronchial valve implantation and shows up its crucial therapeutic role in severe COPD

Lung cancer requires multidisciplinary treatment to improve patient survival: A case report

The present study reports two cases of lung cancer with the involvement of the pleura. The diagnosis of adenocarcinoma with epidermal growth factor receptor (EGFR) mutation was made following repeated thoracentesis with cytology of pleural fluid and thoracoscopy with pleural biopsies. Talc pleurodesis was successfully performed in both cases subsequent to diagnosis. Following talc pleurodesis, the first patient (62 years old; male; non-smoker) underwent 3 cycles of cisplatin/vinorelbine chemotherapy, with a poor response. Concurrently, due to the presence of an EGFR mutation, treatment with gefitinib was initiated, with the patient achieving a good response for ~12 months. The residual tumor was treated with stereotactic radiotherapy and the patient continued gefitinib treatment. The patient is presently in good health, has not exhibited any signs of relapse and is continuing gefitinib treatment without side effects. The second patient (53 years old; male ex-smoker) underwent treatment with gefitinib subsequent to talc pleurodesis for a total of 15 months. In addition, radiotherapy (60 Gy) on the residual lesion was performed. Subsequently, second-line therapy with cisplatin/premetrexed was prescribed and followed by maintenance treatment with premetrexed. Three years after diagnosis, the patient did not exhibit any signs of recurrence. These two cases highlight the difficulty in treating advanced stage lung cancer, despite the presence of EGFR mutation. Each lung cancer is different and requires the physician to possess a wide range of knowledge of the therapeutic options available, in addition to careful monitoring in order to adjust the treatment over time. A multidisciplinary approach, involving surgeons, radiation oncologists, pulmonologists and oncologists, is required to optimize the survival and quality of life of patients with lung cancer

SARS-Cov-2 pneumonia and concurrent myelodysplasia complicated by pseudomonas aeruginosa over-infection

The new virus called severe acute respiratory syndrome coronavirus 2 (SARSCov-2) causing Coronavirus disease 2019 (COVID-19) has spread quickly in several countries and it has become pandemic. Different types of clinical manifestations are attributed to this infection. Some mechanisms related to the infection regarding the immune response are not still elucidated. Herein we reported a case of a 66-years-old patient affected by myelodysplasia who was referred to our hospital because of clinical and radiological manifestations of viral pneumonia. The clinical course has become complicated due to bacterial secondary over-infection by Pseudomonas aeruginosa during stay in internal medicine unit whilst a persistent positive oral and naso-pharyngeal swab test was reported up to 100 days of admission. The patient had a fast clinical and radiological worsening that led her to be admitted to an intensive care unit. Despite intubation and mechanical ventilation she died in a few days
