Design considerations of a randomized clinical trial on a cognitive behavioural intervention using communication and information technologies for man…

2013

Background Psychological treatments have been successful in treating chronic low back pain (CLBP). However, the effect sizes are still modest and there is room for improvement. A way to progress is by enhancing treatment adherence and self-management using information and communication technologies (ICTs). Therefore, the objective of this study was to design a trial investigating the short- and long-term efficacy of cognitive behavioural treatment (CBT) for CLBP using or not ICTs. A secondary objective of this trial will be to evaluate the influence of relevant variables on treatment response. Possible barriers in the implementation of CBT with and without ICT will also be investigated. Met…

Statins, Fracture Risk, and Bone Remodeling: What Is True?

2006

Besides the action on plasma lipid levels, statins show a series of ancillary effects defined as all of their vascular and nonvascular effects independent from the cholesterol reduction. It has been recently hypothesized that one of these ancillary effects could be the improvement of bone health, due to the interference with bone metabolism. This may potentially represent the rationale for statins' use in the treatment of osteoporosis, the most common disease of the bone. Both experimental observations and clinical studies on this topic generated a number of conflicting results; however, the largest randomized clinical trials, the Scandinavian Simvastatin Survival Study (4S), Long Term Inte…

Evaluation of prostate segmentation algorithms for MRI: The PROMISE12 challenge

2014

Contains fulltext : 137969.pdf (Publisher’s version ) (Open Access) Prostate MRI image segmentation has been an area of intense research due to the increased use of MRI as a modality for the clinical workup of prostate cancer. Segmentation is useful for various tasks, e.g. to accurately localize prostate boundaries for radiotherapy or to initialize multi-modal registration algorithms. In the past, it has been difficult for research groups to evaluate prostate segmentation algorithms on multi-center, multi-vendor and multi-protocol data. Especially because we are dealing with MR images, image appearance, resolution and the presence of artifacts are affected by differences in scanners and/or …

Partial Sleep Restriction Activates Immune Response-Related Gene Expression Pathways: Experimental and Epidemiological Studies in Humans

2013

Epidemiological studies have shown that short or insufficient sleep is associated with increased risk for metabolic diseases and mortality. To elucidate mechanisms behind this connection, we aimed to identify genes and pathways affected by experimentally induced, partial sleep restriction and to verify their connection to insufficient sleep at population level. The experimental design simulated sleep restriction during a working week: sleep of healthy men (N = 9) was restricted to 4 h/night for five nights. The control subjects (N = 4) spent 8 h/night in bed. Leukocyte RNA expression was analyzed at baseline, after sleep restriction, and after recovery using whole genome microarrays complem…

The EU project "United4Health": Results and experiences from automatic health status assessment in a Norwegian telemedicine trial system.

2017

Introduction Patients with chronic obstructive pulmonary disease require help in daily life situations to increase their individual perception of security, especially under worsened medical conditions. Unnecessary hospital (re-)admissions and home visits by doctors or nurses shall be avoided. This study evaluates the results from a two-year telemedicine field trial for automatic health status assessment based on remote monitoring and analysis of a long time series of vital signs data from patients at home over periods of weeks or months. Methods After discharge from hospital treatment for acute exacerbations, 94 patients were recruited for follow-up by the trial system. The system supported…

Telemedicine to support coping resources in home-living patients diagnosed with chronic obstructive pulmonary disease: Patients’ experiences

2016

Introduction The way in which telemedicine contributes to promote coping and independence might be undervalued in the development of telemedicine solutions and the implementation of telemedicine interventions. This study explored how home-living patients diagnosed with chronic obstructive pulmonary disease (COPD) experienced follow-up using telemedicine, and the extent to which the implemented technology was able to support and improve the patients’ coping resources and independence. Methods A qualitative approach with individual semi-structured interviews was used. Ten patients diagnosed with COPD participated. The data were transcribed verbatim and a qualitative content analysis method wa…

Efficiency of transgenesis using sperm-mediated gene transfer: generation of hDAF transgenic pigs.

2000

SINCE the beginning of this century, replacement of failing human organs with their animal counterparts has been an interesting topic of debate for writers and scientists. In the 1960s, prolonged survival after kidney transplantation from chimpanzee to human was obtained in the United States and Europe. Nevertheless, both the progressive improvement in surgical technique and in immunosuppressant therapy and the availability of cadaveric organs and living donation have reduced the interest in xenotransplantation. Because of the increasing requests for organs and the lack of donors to meet that need, xenotransplantation has become a reliable option again for temporary organ replacement (eg, o…

Cancer mortality inequalities in urban areas: a Bayesian small area analysis in Spanish cities

2011

incluye "Erratum to: Cancer mortality inequalities in urban areas: a Bayesian small area analysis in Spanish cities" BACKGROUND: Intra-urban inequalities in mortality have been infrequently analysed in European contexts. The aim of the present study was to analyse patterns of cancer mortality and their relationship with socioeconomic deprivation in small areas in 11 Spanish cities. METHODS: It is a cross-sectional ecological design using mortality data (years 1996-2003). Units of analysis were the census tracts. A deprivation index was calculated for each census tract. In order to control the variability in estimating the risk of dying we used Bayesian models. We present the RR of the censu…
