Background and Objectives: bedside cardiac ultrasound is a widely adopted method in Emergency Departments (ED) for extending physical examination and refining clinical diagnosis. However, in the setting of hemodynamically-stable pulmonary embolism, the diagnostic role of echocardiography is still the subject of debate. In light of its high specificity and low sensitivity, some authors suggest that echocardiographic signs of right ventricle overload could be used to rule-in pulmonary embolism. In this study, we aimed to clarify the diagnostic role of echocardiographic signs of right ventricle overload in the setting of hemodynamically-stable pulmonary embolism in the ED. Materials and Methods: we performed a systematic review of literature in PubMed, Web of Science and Cochrane databases, considering the echocardiographic signs for the diagnosis of pulmonary embolism in the ED. Studies considering unstable or shocked patients were excluded. Papers enrolling hemodynamically stable subjects were selected. We performed a diagnostic test accuracy meta-analysis for each sign, and then performed a critical evaluation according to pretest probability, assessed with Wells’ score for pulmonary embolism. Results: 10 studies were finally included. We observed a good specificity and a low sensitivity of each echocardiographic sign of right ventricle overload. However, once stratified by the Wells’ score, the post-test probability only increased among high-risk patients. Conclusions: signs of echocardiographic right ventricle overload should not be used to modify the clinical behavior in low- and intermediate- risk patients according to Wells’ score classification. Among high-risk patients, however, echocardiographic signs could help a physician in detecting patients with the highest probability of pulmonary embolism, necessitating a confirmation by computed tomography with pulmonary angiography. However, a focused cardiac and thoracic ultrasound investigation is useful for the differential diagnosis of dyspnea and chest pain in the ED.

Purpose: Hyponatremia is the most common electrolyte disorder in hospitalized patients, and it might be an indicator of poor prognosis and might have negative effects on hospitalization length and quality of life in non-malignant as well as in malignant diseases. The aim of this study is to determine the impact of hyponatremia on the length and on the cost of hospitalization as well as on outcome in cancer patients. Methods: The present study includes 105 consecutive cancer patients hospitalized at our institution from June 2013 to December 2013. Data regarding age, sex, staging, histology, chemotherapy, and serum sodium levels at admission, during hospitalization, and at discharge were recorded and statistically analyzed. Impact of hyponatremia on length and cost of hospitalization and on outcome was evaluated. Results: A significant difference in overall survival since the date of admission was observed between eunatremic and hyponatremic patients (p = 0.0255). A statistically significant correlation was also found between the length of stay and the detection of hyponatremia. At multivariate analysis, hyponatremia at admission, severity of hyponatremia, and stage of disease resulted independent prognostic factors. Furthermore, a patient with moderate or severe hyponatremia cost, in rate terms, 128 and 299% more than a normonatremic patient, respectively. Conclusions: The occurrence of hyponatremia at the admission or during the hospitalization may represent a significant factor influencing the outcome and the length of hospitalization. Acting effective and timely on the normalization of sodium levels might have a positive effect on prognosis in this setting of patients, as well as on the length of stay in hospital, thus potentially resulting in savings.

Aims and background Although worldwide use of asbestos has decreased, the incidence of malignant pleural mesothelioma (MPM) is expected to increase over the next few decades. A number of scoring systems has been proposed to assess clinicopathologic features and to predict the prognosis. We assessed the relationship between patients’ features and disease evolution in order to choose the best treatment able to prolong overall survival (OS) and progression-free survival (PFS). Methods We retrospectively analyzed patients with locally advanced or metastatic MPM, treated at the Department of Medical Oncology, Università Politecnica Marche, Italy, from January 2003 to September 2013. Data on age, sex, smoking history, asbestos exposure, performance status, tumor stage, histology, type of treatment, and routine laboratory tests including complete blood count panel, date of death, or censored status were collected. The OS and PFS were estimated using Kaplan-Meier method and Cox analysis was performed to analyze the prognostic relevance of clinical parameters. Results We enrolled a total of 62 patients. Univariate analysis showed that histologic type, performance status, response to first-line therapy, pretreatment hemoglobin levels, and plasmatic Ca125 were significant prognostic factors. Conversely, no significant correlation was found between age, sex, smoking history, reported exposure to asbestos, stages at diagnosis, treatments, and OS and PFS. Conclusions Our results showed that anemia and increased Ca125 might be considered negative prognostic parameters in MPM patients and confirmed the prognostic role of histotype, performance status, and response to first-line chemotherapy.

Purpose: Hyponatraemia is one of the most common tumour-related electrolyte disorders. Several clinical, histological and serum factors have been found to influence prognosis, but, to date, there are no studies focusing on the prognostic role of hyponatraemia in mesothelioma. The aim of this study was to assess the prognostic role of hyponatraemia in malignant pleural mesothelioma.Methods: We analysed 62 consecutive patients with histologically or cytologically proven advanced malignant pleural mesothelioma undergoing chemotherapy at our institution between January 2003 and September 2013. Results: All patients received a first-line pemetrexed-based chemotherapy. A second-line chemotherapy was administered to 29 patients.The onset of hyponatraemia (serum sodium
