    The paper deals with the main results of the Italian-American archaeological research project at Bieta Giyorgis, N of Aksum (Tigrai, Ethiopia). The computer applications used in the management and interpretation of the collected data are discussed

    The work presented in this paper is in the frame of MICIE EU FP7 project (Tool for systemic risk analysis and secure mediation of data exchanged across linked CI information infrastructures), which has the main aim of designing and implementing a so- called MICIE alerting system to identify, in real time, the level of possible threats induced on a given Critical Infrastructure (CI) by undesired events happened in the same CI and/or in other interdependent CIs. Heterogeneous models, as the ones presented in this paper, are under development to perform short term predictions of the QoS of the CIs according to the services of the CI, the level of interdependences between the CIs, and the undesired events identified in the reference scenario

    Planned Cesarean Delivery and Urinary Retention Associated With Spinal Morphine

    &lt;p&gt;Cesarean delivery (CD) is the second most commonly performed surgery in the United States. As such, prevention of complications associated with this procedure is a top priority in nursing care. Nurses at the study insti- tution perceived that postcesarean patients experienced increased uri- nary retention after use of spinal morphine for postoperative pain relief. This observation prompted a review of the literature indicating that limited research had been conducted in this area. The purpose of this study was to explore the relationship of postelective CD urinary reten- tion and dose of spinal morphine. A retrospective, quasi-experimental, three-group design was used. Records of 150 patients, ages 17 to 39, undergoing elective primary or repeat CD were examined. Morphine doses included 100, 150, and 200 mcg. No statistically significant differ- ences were found between the three groups.&lt;/p&gt;</jats:p

    Improving the EHMRG Prognostic Evaluation of Acute Heart Failure with TAPSE/PASp: A Sequential Approach

    The Emergency Heart Failure Mortality Risk Grade (EHMRG) can predict short-term mortality in patients admitted for acute heart failure (AHF) in the emergency department (ED). This paper aimed to evaluate if TAPSE/PASp, an echocardiographic marker of ventricular desynchronization, can improve in-hospital death prediction in patients at moderate-to-high risk, according to EHMRG score classification. From 1 January 2018 to 30 December 2019, we retrospectively enrolled all the consecutive subjects admitted to our Internal Medicine Department for AHF from the ED. We performed bedside echocardiography within the first 24 h of admission. We evaluated EHMRG and NYHA in the ED, days of admission in Internal Medicine, and in-hospital mortality. We assessed cutoffs with ROC curve analysis and survival with Kaplan–Meier and Cox regression. We obtained a cohort of 439 subjects; 10.3% underwent in-hospital death. Patients with normal TAPSE/PASp in EHMRG Classes 4, 5a, and 5b had higher survival rates (100%, 100%, and 94.3%, respectively), while subjects with pathologic TAPSE/PASp had lower survival rates (81.8%, 78.3%, and 43.4%, respectively) (p < 0.0001, log-rank test). TAPSE/PASp, an echocardiographic marker of ventricular desynchronization, can further stratify the risk of in-hospital death evaluated by EHMRG
