The Italian Multiple Sclerosis Database Network (MSDN): The risk of worsening according to IFNβ exposure in multiple sclerosis
2006
We evaluated the risk of worsening according to the length of exposure to interferon beta (IFNβ)ina large cohort of 2090 multiple sclerosis patients collected by the Italian MS Database Network. Overall 44-140 patient-visits with a follow-up of 22-143 patient-years were evaluated. Forty-one per cent of patients were exposed to IFNβ for up to 2 years, 39% for 2- 4 years and 20% for more than 4 years. A Cox regression model was used to analyse two clinical outcomes: disability progression and worsening of relapse rate. The technique of propensity score was applied to reduce bias in the comparison of non-randomized groups. The risks of disability progression (HR=0.23; 95% CI: 0.17 - 0.30) and …
Response of the aging eye to first day of modern material contact lens wear
2018
Objectives: To investigate the ocular surface of an aged population wearing a daily disposable contact lens over their first day of wear. Methods: Forty eyes from forty presbyopic subjects were fitted a daily CL (Delefilcon A). Tear osmolarity, tear meniscus area (TMA) and ocular surface aberrations (total higher order root means square (RMS)) were assessed at baseline (t0), at 20 minutes (t1) and after 8 hours (t2) of wear. Fluorescein corneal and conjunctival staining and tear break up time (TBUT) were performed at t0 and t2. Results: No statistically significant changes were found between t0, t1 and t2 for TMA, and between t0 and t2 for fluorescein corneal and conjunctival staining. TBUT…
The effect of vibration therapy on neck myofascial trigger points: A randomized controlled pilot study
2020
[EN] Background: The purpose of this study was to evaluate the effect of low-frequency self-administered vibration therapy into myofascial trigger points in the upper trapezius and levator scapulae on patients with chronic non-specific neck pain. Methods: Twenty-eight patients with chronic non-specific neck pain were randomly assigned into a vibration group, receiving 10 self-applied sessions of vibration therapy in the upper trapezius and levator scapulae trigger points; or a control group, receiving no intervention. Self-reported neck pain and disability (Neck Disability Index) and pressure pain threshold were assessed at baseline and after the first, fifth and 10th treatment sessions. Fi…
Assessment of corneal morphological changes induced by the use of daily disposable contact lenses.
2015
To assess the effect of different disposable soft contact lenses upon corneal thickness, and upon anterior and posterior corneal curvatures using a dual-Scheimpflug imaging based device.Twenty-eight young, healthy subjects wore four different types of daily disposable soft contact lenses on four different days: Dailies Total1, Proclear 1 Day, Clariti 1-Day and 1-Day Acuvue Moist. The lenses had different material and water content. Pachymetry maps and keratometry values were obtained using the Galilei G4 twice a day: one before putting the lens on and one after an eight-hour period of contact-lens wear. Measurements were also recorded without any contact lenses being worn during a day.Clari…
Diurnal variations in visual performance for disposable contact lenses.
2013
The purpose of this study is to compare the visual performance provided by different daily disposable contact lenses and to analyze its variation over time.Visual performance was evaluated in terms of visual acuity (VA) and contrast sensitivity (CS) in 15 myopic subjects (-0.50 to -4.00 diopters) who had been previously fitted with each one of the following seven types of soft contact lenses: DAILIES TOTAL1 (Alcon, Forth Worth, TX), DAILIES AquaComfort Plus (Alcon), 1-DAY ACUVUE TruEye (JohnsonJohnson Vision Care, Jacksonville, FL), 1-DAY ACUVUE MOIST (JohnsonJohnson Vision Care), SofLens daily disposable (BauschLomb, Rochester, NY), Proclear 1 Day (CooperVision, Fairport, NY), and Clariti …
Evidence for a white matter lesion size threshold to support the diagnosis of relapsing remitting multiple sclerosis
2018
Abstract Background The number of white matter lesions (WML) in brain MRI is the most established paraclinical tool to support the diagnosis of multiple sclerosis (MS) and to monitor its course. Diagnostic criteria have stipulated a minimum detectable diameter of 3 mm per WML, although this threshold is not evidence-based. We aimed to provide a rationale for a WML size threshold for three-dimensional MRI sequences at 3 T by comparing patients with relapsing-remitting MS (RRMS) to control subjects (CS). Methods We analyzed MR images from two cohorts, obtained at scanners from two different vendors, each comprising patients with RRMS and CS. Both cohorts were examined with FLAIR and T1w seque…
Prevalence and incidence of workplace bullying among Spanish employees working with people with intellectual disability
2012
Abstract Background Although workplace bullying is a severe psychosocial risk with a high prevalence, there is a lack of studies addressing its incidence, particularly among staff working with people with intellectual disability. Objectives We examined the prevalence and incidence of workplace bullying in a sample of Spanish employees working with people with intellectual disability. The socio-demographic characteristics of victims and non-victims of workplace bullying were also analyzed. Methods Multicenter study with two phases (T1 and T2) carried out in Valencia (Spain). The sample consisted of 696 employees from 66 centers in T1. One year later (T2), 422 employees from 61 centers agreed…
Rituximab versus azathioprine for ANCA-associated vasculitis maintenance therapy: Impact on global disability and health-related quality of life
2016
IF 2.724 (2014); International audience; OBJECTIVES: To investigate the effects on health-related quality of life (HRQOL) and functional capability of rituximab vs azathioprine for ANCA-associated vasculitis (AAV) maintenance therapy. METHODS: In a 24-month phase III randomised-controlled trial, 115 patients over time received rituximab or azathioprine for AAV maintenance therapy. Mean changes of 36-item Short-form Health Survey (SF-36) and Health Assessment Questionnaire (HAQ) scores from baseline were analysed. RESULTS: Mean improvements of HAQ scores, from baseline to month 24 were significantly better for the rituximab (0.16 points lower) than the azathioprine group (p=0.038). As demons…
Working memory and everyday cognition in adults with Down's syndrome.
2001
A number of previous studies have suggested that young people with Down's syndrome (DS) have a specific deficit of the phonological loop component of the working memory. However, there have also been studies which have proposed a specific deficit of the central executive component of working memory and suggested similarities of working memory functioning with patients with Alzheimer's disease. Fifteen middle-aged people with DS were matched for their individual scores of non-verbal intelligence to 15 individuals with mixed aetiology of intellectual disability. A versatile range of tasks was used in order to evaluate the functioning of working memory components. In addition, several everyday…
Utility of the World Health Organization Disability Assessment Schedule II in schizophrenia.
2011
The World Health Organization Disability Assessment Schedule II (WHODAS II) was developed for assessing disability. This study provides data on the validity and utility of the Spanish version of the WHODAS II in a large sample of patients with schizophrenia.The sample included 352 patients with a schizophrenia spectrum disorder. They completed a comprehensive assessment battery including measures of psychopathology, functionality and quality-of-life. A sub-sample of 36 patients was retested after six months to assess its temporal stability.Participation in society (6.3%) and Life activities (4.0%) were the domains with the highest percentage of missing data. The internal consistency (Cronba…
