New organisation for follow-up and assessment of treatment efficacy in sleep apnoea.
2019
Obstructive sleep apnoea (OSA) is a highly prevalent disease, and there is an increased demand for OSA diagnosis and treatment. However, resources are limited compared with the growing needs for OSA diagnosis and management, and alternative strategies need to be developed to optimise the OSA clinical pathway. In this review, we propose a management strategy for OSA, and in general for sleep-disordered breathing, to be implemented from diagnosis to follow-up. For this purpose, the best current options seem to be: 1) networking at different levels of care, from primary physicians to specialised sleep laboratories; and 2) use of telemedicine. Telemedicine can contribute to the improved cost-ef…
Development and Validation of the OSA-CPAP Perceived Competence Evaluation Interview
2021
Continuous positive airway pressure (CPAP) is one of the most common therapies for Obstructive Sleep Apnea (OSA). We present a brief, patient-reported outcome measure used to assess patients' levels of adherence with CPAP treatment.A questionnaire was developed based on academic literature. We qualitatively tested a pool of 18 items. It was tested in a sample of 174 patients from the Hospital La Princesa. Next, 1021 patients from Catalonia were evaluated.5 items were removed. Nominal groups referred to three areas: general knowledge about OSA and its risks; CPAP treatment information and expectations; CPAP use, monitoring, and confidence with its use. The 13 retained items maintained the sa…
Mechanostructural adaptations preceding postpneumonectomy lung growth
2012
In many species, pneumonectomy results in compensatory growth in the remaining lung. Although the late mechanical consequences of murine pneumonectomy are known, little is known about the anatomic adaptations and respiratory mechanics during compensatory lung growth. To investigate the structural and mechanical changes during compensatory growth, mice were studied for 21 days after left pneumonectomy using microCT and respiratory system impedance (FlexiVent). Anatomic changes after left pneumonectomy included minimal mediastinal shift or chestwall remodeling, but significant displacement of the heart and cardiac lobe. Mean displacement of the cardiac lobe centroid was 5.2 ± 0.8 mm. Lung imp…
Dynamic determination of oxygenation and lung compliance in murine pneumonectomy.
2011
Thoracic surgical procedures in mice have been applied to a wide range of investigations, but little is known about the murine physiologic response to pulmonary surgery. Using continuous arterial oximetry monitoring and the FlexiVent murine ventilator, the authors investigated the effect of anesthesia and pneumonectomy on mouse oxygen saturation and lung mechanics. Sedation resulted in a dose-dependent decline of oxygen saturation that ranged from 55% to 82%. Oxygen saturation was restored by mechanical ventilation with increased rate and tidal volumes. In the mouse strain studied, optimal ventilatory rates were a rate of 200/minute and a tidal volume of 10 mL/kg. Sustained inflation pressu…
Influence of Organizational Culture on Employees Information Security Policy Compliance in Ethiopian Companies
2021
Information security is one of the organizations' top agendas worldwide. Similarly, there is a growing trend in the kinds and rate of security breaches. Information security experts and scholars concentrate on outsiders' threats; conversely, insiders are responsible for most security breaches in organizations. Further, the majority of information security research findings are limited to solutions that are technically focused. However, it is now recognized that the technological approach alone does not carry the security level needed. So this led researchers to embark on socio-technical approaches. Thus, this study explores organizational culture's effect on employees' intention to comply w…
Ethical challenges in care for older patients who resist help
2014
Background: Situations where patients resist necessary help can be professionally and ethically challenging for health professionals, and the risk of paternalism, abuse and coercion are present. Research question: The purpose of this study was to examine ethical challenges in situations where the patient resists healthcare. Research design: The method used was clinical application research. Academic staff and clinical co-researchers collaborated in a hermeneutical process to shed light on situations and create a basis for new action. Participants and research context: Four research groups were established. Each group consisted of six to eight clinical co-researchers, all employees with diff…
Robust Control of Nonlinear Systems: An Unknown Input Observer Based Approach
2023
Questa tesi propone un controllore robusto per sistemi non lineari tramite l'utilizzo di un osservatore ad ingressi sconosciuti. Attraverso un'opportuna riformulazione dinamica del modello, un generico sistema non lineare viene descritto come la somma di due funzioni, la prima lineare e nota e la seconda altamente non lineare e sconosciuta, derivante dalla conoscenza imperfetta del modello dinamico, dei parametri, o di eventuali disturbi esogeni agenti sul sistema etc., modellabili come perturbazioni (disturbi) della funzione lineare. Questa semplificazione consente una vantaggiosa descrizione dinamica del sistema in forma matriciale. Le informazioni necessarie sono stimate attraverso l'uti…
Fractional calculus application to visco-elastic solid
2009
It is widely known that fractional derivative is the best mathematical tool to describe visco-elastic constitutive law. In this paper it is shown that as soon as we assume the creep compliance function as power law type, as in the linearized version of the Nutting equation, then the fractional constitutive law appears in a natural way. Moreover, using Nutting equation for the creep function, the relaxation modulus is also of power law type whose coefficients (intensity and exponent) are strictly related to those of the creep compliance. It follows that by a simple creep test (or relaxation test) by means of a best fitting procedure we may easily evaluate the parameters of Nutting equation a…
Evaluation of residual stress during fatigue test in a FSW joint
2007
At present, friction stir welding (FSW) represents one of the most interesting techniques in the field of welding. The process is has been implemented in industrial practice for joining aluminium alloys, while the welding of the titanium alloy and the steels is still primarily in a developmental stage. The thermo-mechanical action of the tool causes a residual stress field in the FSW joint. Although, the peak temperatures of the process are relatively low; residual stresses similar to the traditional welding technique may develop in the FSW joint. Moreover, the restraints of clamps, which are used for fixing the plates during the process, impede the relief of the heated zones that causes lo…
The influence of illness severity on health satisfaction in patients with cardiovascular disease: The mediating role of illness perception and self-e…
2015
The importance of psychological factors in improving conditions of cardiovascular disease (CVD) patients is stressed by the guidelines for their prevention and rehabilitation, but little is known about the impact of illness severity on patients well-being, and on the psychosocial variables that may mediate this association. The aim of this study was to investigate the role of illness perception and self-efficacy beliefs on the relationship between illness severity and health satisfaction in 75 CVD patients undergoing rehabilitation (80% men; mean age = 65.44) at the St. Luca Hospital, Istituto Auxologico Italiano, Milan, Italy. Illness severity was measured in terms of left ventricular ejec…
