Comparison between doppler-echocardiography and uncalibrated pulse contour method for cardiac output measurement. a multicenter observational study
2016
Objectives: Echocardiography and pulse contour methods allow, respectively, noninvasive and less invasive cardiac output estimation. The aim of the present study was to compare Doppler echocardiography with the pulse contour method MostCare for cardiac output estimation in a large and nonselected critically ill population. Design: A prospective multicenter observational comparison study. Setting: The study was conducted in 15 European medicosurgical ICUs. Patients: We assessed cardiac output in 400 patients in whom an echocardiographic evaluation was performed as a routine need or for cardiocirculatory assessment. Interventions: None. Measurements and Main Results: One echocardiographic car…
Ultrasonography in Heart Failure: A Story that Matters
2019
Abstract Heart failure (HF) is a clinical syndrome caused by structural and/or functional cardiac abnormalities, resulting in a reduced cardiac output and/or elevated intracardiac pressures at rest or during stress. It is the leading cause of hospitalization in Internal Medicine departments. This article aims at reviewing evidence of the importance of ultrasound in HF both for hospitalized patients and in the follow-up. Ultrasound may be used as a recovery monitoring instrument at the bedside and also as a global cardiovascular assessment tool for these patients. HF represents an exciting opportunity to create an integrative ultrasound approach in Internal Medicine and/or Geriatric departme…
Arterial pCO2 and Blood Flow in Different Parts of the Central Nervous System of the Anesthetized Cat
1969
It cannot be regarded as proven that the mechanisms involved in the regulation of local circulation are identical in all parts of the central nervous system. Evidence has been presented that carbon dioxide exerts differential effects in different parts of the CNS [2, 3, 7, 10].
Haemodynamics of primary aldosteronism associated with adrenocortical adenoma: insights from bioimpedance cardiography measurements
2020
In mid 1950s, Dr Jerome Conn described a patient with hypertension, and renal potassium wasting associated with adrenocortical adenoma and increased urinary excretion of a sodium-retaining hormone, initially termed electrocortin, which was subsequently shown to be aldosterone. This was the first full report of primary hyperaldosteronism associated with an aldosterone-producing adenoma (APA). It subsequently became apparent that similar abnormalities can occur in the absence of an adrenocortical tumor, and it is now recognized that the APA is just one of many subtypes of primary aldosteronism (PA).
Description of the response of a new multi-parametric brain sensor to physiological and pathophysiological challenges in the cortex of juvenile pigs
2014
AIM Monitoring of intracranial pressure (ICP), local cerebral blood flow (CBF) and oxygen is part of modern intensive critical care medicine. Preclinical evaluation of newly developed catheters that should monitor several parameters simultaneously is reported poorly in the literature. The goal of our study was (1) to evaluate a new multi-parametric sensor in brain tissue and (2) to establish a testing protocol using pathophysiological challenges that target measured parameters of the sensor and autoregulatory boundaries and could be used as preclinical standard protocol in future studies. MATERIAL AND METHODS We describe data from 12 new multi-parametric brain sensors (MPBS) that were impla…
Obraz Hrista v romane Čingiza Ajtmatova "Plaha"
2011
Aitmatov introduced a biblical motif into his novel – he chose Christ examination by Pilate. The writer extended the meaning of the scene, he altered its essence and “genre,” changing it into philosophical disputation. He also invented the story of Christ sailing with his mother on the Nile and their miraculous rescue by a crocodile. These scenes are presented in such a way that they remind the myth of the birth and death of Christ which allows rating Aitmatov's figure of Christ to the fifth category of literary embodiment of Christ proposed by T. Ziołkowski and called CHRIST AS A MYTH. A figure of Christ in the novel is a symbol of the highest perfection of humanity.
Vascular resistance arm of the baroreflex: methodology and comparison with the cardiac chronotropic arm.
2020
Baroreflex response consists of cardiac chronotropic (effect on heart rate), cardiac inotropic (on contractility), venous (on venous return) and vascular (on vascular resistance) arms. Because of its measurement simplicity, cardiac chronotropic arm is most often analysed. The aim was to introduce a method to assess vascular baroreflex arm, and to characterize its changes during stress. We evaluated the effect of orthostasis and mental arithmetics (MA) in 39 (22 female, median age: 18.7 yrs.) and 36 (21 female, 19.2 yrs.) healthy volunteers, respectively. We recorded systolic and mean blood pressure (SBP and MBP) by volume-clamp method and R-R interval (RR) by ECG. Cardiac output (CO) was re…
Evaluating the Reform of Healthcare System in Sicily: variations of efficiency and appropriateness between 2008 and 2010
2022

 
 Background. Sicilian government has developed a very ambitious Reform through the Regional Law n. 5 (14th April 2009). Hospitals were requested to ensure the quality of care through monitoring of appropriateness and quality of service. The aim of this study was to assess variations of efficiency and organizational appropriateness of healthcare delivery before and after this Reform and to show patterns associated to different types of healthcare delivery organizations.
 Methods. This study was based on repeated cross-sectional data for 118 (out of 129) short-term, acute-care, non teaching-and-research Sicilian hospitals, in 2008 and 2010. Congestion and slacks analysis was…
On the Conditions of Price Consistency in the Input-Output Model
2013
The input-ouput model remains the basis of most SAM or CGE models. It actually uses two periods: the prices indexes solve it with the current period coefficients; the corresponding physical model is monoperiodic: the current prices solve it with the base period coefficients. The Leontief model is not consistent --- both models diverge generally --- unless the interindustry matrix of direct and indirect quantities of labor is stable over time. This implies that the vertically integrated labor coefficients are stable. This assumption is satisfied when the physical production coefficients and the physical labor coefficients are stable over time, two very strong assumptions.
Enabling Soft Frequency Reuse and Stienen's Cell Partition in Two-Tier Heterogeneous Networks: Cell Deployment and Coverage Analysis
2021
Heterogeneous cellular networks (HetNets) are one of the key enabling technologies for fifth generation (5 G) networks. In HetNets, the use of small base stations (SBSs) inside the coverage area of a macro base station (MBS) offers higher throughput and improved coverage. However, such multi-tier base station deployment introduces new challenges, e.g., (i) All users experience significant inter-cell interference (ICI) due to frequency reuse, (ii) SBS associated users experience severe MBS-interference due to higher MBS transmit power, and (iii) MBS coverage edge users receive lower signal-to-interference ratio (SIR) due to longer distances. To address the aforementioned challenges, this wor…
