Impact of osteoporosis and vertebral fractures on quality-of-life. a population-based study in Valencia, Spain (The FRAVO Study)

2011

Abstract Background To describe the health related quality of life in a population sample of postmenopausal women over the age of 50 and resident in the city of Valencia (Spain), according to the presence/absence of osteoporosis and the severity of prevalent morphometric vertebral fractures. Methods A cross-sectional age-stratified population-based sample of 804 postmenopausal women of 50 years of age and older were assessed with the SF-12 questionnaire. Information about demographic features, lifestyle, clinical features, educational level, anti-osteoporotic and other treatments, comorbidities and risk factors for osteoporosis were collected using an interviewer-administered questionnaire …

Computer-aided navigation in neurosurgery

2003

The article comprises three main parts: a historical review on navigation, the mathematical basics for calculation and the clinical applications of navigation devices. Main historical steps are described from the first idea till the realisation of the frame-based and frameless navigation devices including robots. In particular the idea of robots can be traced back to the Iliad of Homer, the first testimony of European literature over 2500 years ago. In the second part the mathematical calculation of the mapping between the navigation and the image space is demonstrated, including different registration modalities and error estimations. The error of the navigation has to be divided into the …

Endo-neuro-sonography: anatomic aspects of the ventricles.

1997

To evaluate the usefulness of transendoscopic sonography, we have studied the use of a new sonographic probe of 6 F diameter in 11 fresh specimens. We achieved a precise imaging of well known anatomic structures and, moreover, obtained an additional dimension in endoscopy, since the sonographic probe adds a transverse scan to the endoscopic view, like a mini-CT at the tip of the probe. In this way, we also examined the guiding characteristics of this imaging technique, both in real time and on-line. Our results promise further interesting aspects of this technique in minimally invasive neurosurgery and suggest that further development and clinical experience seem to be justified.

A Computerised System for Electrocochleographic (ECOG) Measurement

1982

To study the influence of vitamin A on hearing we choose to examine ECoGs induced by an audible stimulus.The basis of this project is a suitable experimental equipment for inducing and recording inner ear electrical responses in guinea pigs. The problem to be studied asks for a high number of animals and measurements within one animal; furthermore the ECoGs of each animal have to be examined over a long period of time. This calls for a simple and automated measurement and evaluation procedure. In contrats to most ECoG experiments we do not study the influence of special oto — toxic agents (noise,drugs etc) but examine the variation of ECoG signals as caused by different metabolic states of …

Process-Optimized Minimally Invasive Total Hip Replacement via a Direct Anterior Approach with Navigation Control of Leg Length and Offset

2013

The purpose of this study was to analyze a new concept of using the minimally invasive direct anterior approach (DAA) in total hip replacement (THR) in combination with a leg positioner (Rotex-Table) and a modified retractor system (Condor). To control leg length and offset, the navigation system OrthoPilot® (B. Braun, Aesculap) or the Medacta system was used. We retrospectively evaluated the first 100 primary THRs performed with this new concept between 2009 and 2010, regarding the surgical data as well as the radiological and clinical outcome (Hip Disability and Osteoarthritis Outcome score, HOOS). All surgeries were perfomed following a standardized operation technique including navigati…

A novel heuristic algorithm for the modeling and risk assessment of the COVID-19 pandemic phenomenon

2020

This article belongs to the special issue: Soft computing techniques in materials science and engineering Summarization: The modeling and risk assessment of a pandemic phenomenon such as COVID-19 is an important and complicated issue in epidemiology, and such an attempt is of great interest for public health decision-making. To this end, in the present study, based on a recent heuristic algorithm proposed by the authors, the time evolution of COVID-19 is investigated for six different countries/states, namely New York, California, USA, Iran, Sweden and UK. The number of COVID-19-related deaths is used to develop the proposed heuristic model as it is believed that the predicted number of dai…

Knowledge Discovery from Microbiology Data: Many-Sided Analysis of Antibiotic Resistance in Nosocomial Infections

2005

Nosocomial infections and antimicrobial resistance (AR) are highly important problems that impact the morbidity and mortality of hospitalized patients as well as their cost of care. The goal of this paper is to demonstrate our analysis of AR by applying a number of various data mining (DM) techniques to real hospital data. The data for the analysis includes instances of sensitivity of nosocomial infections to antibiotics collected in a hospital over three years 2002-2004. The results of our study show that DM makes it easy for experts to inspect patterns that might otherwise be missed by usual (manual) infection control. However, the clinical relevance and utility of these findings await th…
