Clinical and magnetic resonance imaging predictors of disease progression in multiple sclerosis: a nine-year follow-up study.

2014

Objective: The objective of this paper is to identify clinical or magnetic resonance imaging (MRI) predictors of long-term clinical progression in a large cohort of multiple sclerosis (MS) patients. Methods: A total of 241 relapsing–remitting (RR) MS patients were included in a nine-year follow-up (FU) study. The reference MRIs were acquired at baseline (BL) as part of a multicenter, cross-sectional, clinical-MRI study. Volumetric MRI metrics were measured by a fully automated, operator-independent, multi-parametric segmentation method. Clinical progression was evaluated as defined by: conversion from RR to secondary progressive (SP) disease course; progression of Expanded Disability Status…

Type-D personality and depersonalization are associated with suicidal ideation in the German general population aged 35–74: Results from the Gutenber…

2009

Suicidal ideation (SID) is a major risk factor for suicide attempts. Mental disorders are among the strongest correlates of suicide, with depression and anxiety disorders playing a major role. The present study aims to investigate the contribution of under researched factors contributing to SID such as depersonalization, Type-D personality and cardiovascular risk factors.Factors associated with SID were investigated in a sample of N=5000 participants (aged 35-74 years) of the community-based survey "Gutenberg Heart Study". The factors were assessed by self-report instruments, computer-assisted interviews and medical examination.7.5% of the sample reported SID over the last 2 weeks. In the u…

Frequency-specific network activity predicts bradykinesia severity in Parkinson’s disease

2021

Highlights • Parallel subnetworks are affected in bradykinesia. • The primary motor and the premotor cortex are common nodes with task-specificity. • Beta activity decreases, gamma activity increases with improvement of bradykinesia. • Subthalamic stimulation reduces beta, increases gamma power in ipsilateral cortex. • Subnetworks act with frequency-specific oscillations.

Characteristics of patients with hepatitis C virus-related chronic liver diseases just before the era of oral direct-acting antiviral therapy in Italy

2018

Background In 2017, oral direct-acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) infection became available free of charge for all HCV-RNA-positive patients, irrespective of their fibrosis stage. Aim The aim of this study was to evaluate the characteristics of HCV-related chronic liver disease (CLD) in Italy just before the introduction of DAA therapy. Patients and methods Patients with CLD were enrolled in two national surveys conducted in 2001 and in 2014. The two surveys prospectively enrolled patients aged older than 18 years referring to Italian liver units throughout the country using a similar clinical approach and analytical methods. Results Out of the 12 564 patie…

Quality of Life in a German Graves Orbitopathy Population

2010

To evaluate the validity and responsiveness of a German-language version of the disease-specific Graves orbitopathy quality-of-life questionnaire (GO-QOL).Prospective cross-sectional study.At a multidisciplinary university orbital center, 310 consecutive unselected Graves orbitopathy outpatients answered the GO-QOL before undergoing complete ophthalmic and endocrine assessment. The main outcome measures were the GO-QOL and its 2 subscales, Visual Functioning and Appearance.The QOL scores for the subscales Visual Functioning and Appearance were (mean ± SE) 72.5 ± 1.4 and 71.3 ± 1.5, respectively. Visual Functioning and Appearance were higher in mild (82.2 ± 2.2 and 86.0 ± 17.6) than in moder…

Factors associated with influenza vaccination of hospitalized elderly patients in Spain

2016

Vaccination of the elderly is an important factor in limiting the impact of influenza in the com- munity. The aim of this study was to investigate the factors associated with influenza vacci- nation coverage in hospitalized patients aged 65 years hospitalized due to causes unrelated to influenza in Spain. We carried out a cross-sectional study. Bivariate analysis was performed comparing vaccinated and unvaccinated patients, taking in to account sociodemographic variables and medical risk conditions. Multivariate analysis was per- formed using multilevel regression models. We included 1038 patients: 602 (58%) had received the influenza vaccine in the 2013 - 14 season. Three or more general p…

A current model suggested that the somatic symptom dimension accounts for the adverse effect of depression in patients with coronary heart disease (CHD). In order to test this model we sought to determine in a large population-based sample how symptom dimensions of depression are associated with CHD, biomarkers and traditional risk factors. The associations of cognitive and somatic symptom dimensions of depression with CHD, risk factors, endothelial function, and biomarkers of inflammation and myocardial stress were analyzed cross-sectionally in a sample of n=5000 Mid-Europeans aged 35–74 years from the Gutenberg Health Study (GHS). Only the somatic symptom dimension of depression was assoc…

Objective: Supportive care needs in glioma patients often remain unrecognized, and optimization in assessment is required. First, we aimed at assessing the support needed using a simple structured questionnaire. Second, we investigated the psychosocial burden and support requested from caregivers. Methods: Patients were assessed at three centers during their outpatient visits. They completed the Distress Thermometer (DT; score ≥ 6 indicated significant burden in brain tumor patients), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-C30+BN20, and the Patients' Perspective Questionnaire (PPQ) that assessed psychosocial distress as well …
