Erythrocyte deformability, plasma lipid peroxidation and plasma protein oxidation in a group of OSAS subjects

2016

Considering that obstructive sleep apnea syndrome (OSAS) is usually associated with endothelial dysfunction, atherosclerosis and cardiovascular disorders, our aim was to examine the erythrocyte deformability and the oxidative status in a group of OSAS subjects. We consecutively enrolled 48 subjects with OSAS defined after a 1-night cardiorespiratory sleep study, subsequently subdivided according to the apnea/hypopnea index (AHI) value in two subgroups: Low (L = 21 subjects with AHI30) and High (H = 27 subjects with AHI30). We evaluated the erythrocyte deformability, expressed as elongation index (EI) and the parameters of the oxidative status, such as lipid peroxidation (expressed as thioba…

Food safety in hospital: knowledge, attitudes and practices of nursing staff of two hospitals in Sicily, Italy.

2007

Abstract Background Food hygiene in hospital poses peculiar problems, particularly given the presence of patients who could be more vulnerable than healthy subjects to microbiological and nutritional risks. Moreover, in nosocomial outbreaks of infectious intestinal disease, the mortality risk has been proved to be significantly higher than the community outbreaks and highest for foodborne outbreaks. On the other hand, the common involvement in the role of food handlers of nurses or domestic staff, not specifically trained about food hygiene and HACCP, may represent a further cause of concern. The purpose of this study was to evaluate knowledge, attitudes, and practices concerning food safet…

Visceral obesity and metabolic syndrome: two faces of the same medal?

2009

In this review, we have analyzed the role of visceral obesity in the occurrence of metabolic syndrome (MetS). MetS is a common metabolic disorder that has been related recently to the increasing prevalence of obesity. The disorder is defined in various ways, but in the near future a new definition(s) should be applicable worldwide. The pathophysiology has been largely attributed, in the past years, to insulin resistance, although several epidemiological and pathophysiological data now indicate visceral obesity as a main factor in the occurrence of all the components of MetS. In view of this, relationships among visceral obesity, free fatty acids, dyslipidemia and insulin resistance have bee…

Perception of clinical educational environment by student of physiotherapy based on the Postgraduate Hospital Educational Environment Measurement Que…

2019

Purpose: It aimed at describing the perception of the clinical educational environment by physiotherapy students based on the Postgraduate Hospital Educational Environment Measurement Questionnaire in Chile.Methods: The clinical education environment was evaluated according to the Postgraduate Hospital Educational Environment Measure (PHEEM) by 192 students originally enrolled in the fifth year of the physiotherapy career at 3 different headquarters of the academic institution: Santiago, Viña del Mar, and Concepcion Campus (Metropolitan, Valparaiso, and Bio Bio region, respectively), from March to October 2018. The Cronbach’s α was applied to measure the reliability of the instrument and th…

Medical complications in a telemedicine home care programme for paediatric ventilated patients.

2019

Introduction Advances in paediatric medicine have increased survival rates for patients with severe chronic illnesses, of which the most complex are ventilator-dependent children (VDCs). Although home care improves their quality of life, morbidity and mortality rates are high. Our aim was to study the medical complications (events) that occur at home and assess the usefulness of telemedicine in their detection and treatment. Methods A prospective clinical study (2007–2017) was performed for tracheotomised VDCs. We used a high-density data telemedicine monitoring system from our Paediatric Intensive Care Unit and analysed events during the first two years of home care to study how different …

Usefulness of telemedicine for home ventilator-dependent children.

2018

Introduction Medical care for ventilator-dependent children must avoid hospital confinement, which is detrimental to the patient, their family and Paediatric Intensive Care Unit. Our objective was to assess the role of telemedicine in facilitating early and permanent discharge of such patients to home care. Methods This was a prospective clinical study (2007–2017) in tracheotomised ventilator-dependent children. We used a Big Data Telemedicine home system (Medlinecare 2.1) from the Paediatric Intensive Care Unit. Specialised home-nursing services were available. Clinical events were analysed using the Chi-square test (significance p < 0.05). Families subsequently completed a satisfaction…

Computer-Aided Detection and diagnosis for prostate cancer based on mono and multi-parametric MRI: A review

2015

Prostate cancer is the second most diagnosed cancer of men all over the world. In the last few decades, new imaging techniques based on Magnetic Resonance Imaging (MRI) have been developed to improve diagnosis. In practise, diagnosis can be affected by multiple factors such as observer variability and visibility and complexity of the lesions. In this regard, computer-aided detection and computer-aided diagnosis systems have been designed to help radiologists in their clinical practice. Research on computer-aided systems specifically focused for prostate cancer is a young technology and has been part of a dynamic field of research for the last 10years. This survey aims to provide a comprehen…

Wrong postural hygiene and ergonomics in dental students of the University of Valencia (Spain) (part I)

2017

Introduction Failure to adopt a correct working posture can lead to occupational diseases. Objectives Evaluate knowledge in relation to ergonomics about BHOP concept and its application to routine clinical practice amongst undergraduate and postgraduate dental students in the University of Valencia (Valencia, Spain). Material and methods A study based on interviews of undergraduate and postgraduate dental students in the University of Valencia (Valencia, Spain) was carried out. The information from a total of 336 interviews was used for the statistical analysis, differentiating according to gender and academic year: knowledge of ergonomics, pain prevalence and antecedents, assessment of the…

A Survey of Prostate Segmentation Methodologies in Ultrasound, Magnetic Resonance and Computed Tomography Images

2012

Prostate segmentation is a challenging task, and the challenges significantly differ from one imaging modality to another. Low contrast, speckle, micro-calcifications and imaging artifacts like shadow poses serious challenges to accurate prostate segmentation in transrectal ultrasound (TRUS) images. However in magnetic resonance (MR) images, superior soft tissue contrast highlights large variability in shape, size and texture information inside the prostate. In contrast poor soft tissue contrast between prostate and surrounding tissues in computed tomography (CT) images pose a challenge in accurate prostate segmentation. This article reviews the methods developed for prostate gland segmenta…
