Reliability, validity and responsiveness of the EQ-5D in assessing and valuing health status in patients with social phobia
2013
Abstract Objective The aim of the study was to analyse the psychometric properties of the EQ-5D in patients with social phobia. Methods We used a sample of 445 patients with social phobia with five measurement points over a 30 month period. The discriminative ability of the EQ-5D was analysed by comparing the patients’ responses with the general population and between different disease severity levels. For test-retest reliability we assessed the level of agreement in patients’ responses over time, when there was no change in the Liebowitz Social Anxiety Scale (LSAS). Construct validity was analysed by identifying correlations of the EQ-5D with more specific instruments. For responsiveness w…
Knowledge about glaucoma in the unselected population: a German survey.
2002
Purpose To determine the general population's knowledge about glaucoma. Materials and methods A representative survey of the German population was conducted in which 2,742 men and women were interviewed face to face. The sample was matched with the German population for age, sex, education, income, and other factors. Questions were asked concerning the nature, occurrence, possible risk factors, and course of glaucoma. Results Fifty-one percent of the population had an active knowledge of the term "glaucoma" and 75% had a passive knowledge of the term. Of those interviewees with a passive knowledge, glaucoma was thought to be associated with raised intraocular pressure (IOP) by 28% and loss …
Cardiovascular medication and intraocular pressure: results from the Gutenberg Health Study
2016
BACKGROUND Intraocular pressure (IOP) is well known to be associated with blood pressure and other cardiovascular risk factors. The influence of systemic cardiovascular, in particular antihypertensive, medication on IOP is still controversial. This study analyses the association between the use of cardiovascular medications and IOP in a large European cohort. METHODS The Gutenberg Health Study is a population-based, prospective,observational cohort study in mid-western Germany. IOP was measured using a non-contact tonometer. The medication classes examined were peripheral vasodilators, diuretics, β-blockers (overall, selective and non-selective), calcium channel blockers, renin-angiotensin …
Prevalence of glaucoma and distribution of intraocular pressure in a population. The Casteldaccia Eye Study.
2009
IOP was measured in 1062 middle-aged and elderly subjects of a small Sicilian town, enrolled in a population based survey. The mean IOP was 15.1 +/- 3.7 mmHg without interocular or sex differences. A small but significant age-dependent increase of IOP was found. Circadian and seasonal influences were recorded: IOP was higher in the morning and in winter. The prevalence of chronic open-angle glaucoma was 1.2%, but it grew to 3.6 if only subjects aged 70 years or more were considered. IOP of 24 mmHg or more was found in 2.7%, while 4.3% of subjects showed IOP of 21 mmHg or more. This survey shows that mean IOP of the Mediterranean population studied is similar to the IOP found in other epidem…
PREVALENCE AND ASSOCIATIONS OF MYELINATED RETINAL NERVE FIBERS
2016
PURPOSE To determine the prevalence, ocular, and systemic associations of myelinated retinal nerve fibers (MRNF) in a Caucasian cohort. METHODS The Gutenberg Health Study (GHS) is a population-based, prospective cohort study encompassing 15,010 subjects in Germany. Gutenberg Health Study participants, aged 35 to 74 years, stratified for gender, decades of age, and residence were examined for ophthalmologic and systemic conditions. Optic disc centered and macular photographs were reviewed for the presence of MRNF. RESULTS In 25,728 eyes of 12,906 participants (86.0% of the cohort), the prevalence of MRNF was 0.4%. In a binary logistic regression analysis, MRNF was positively associated with …
High constant incidence rates of second primary cancers of the head and neck: a pooled analysis of 13 cancer registries
2010
Scanty data are available on the incidence (i.e., the absolute risk) of second cancers of the head and neck (HN) and its pattern with age. We investigated this issue using data from a multicentric study of 13 population-based cancer registries from Europe, Canada, Australia and Singapore for the years 1943-2000. A total of 99,257 patients had a first primary HN cancer (15,985 tongue, 22,378 mouth, 20,758 pharyngeal, and 40,190 laryngeal cancer), contributing to 489,855 person-years of follow-up. 1294 of the patients (1.3%) were diagnosed with second HN cancers (342 tongue, 345 mouth, 418 pharynx, and 189 larynx). Male incidence rates of first HN cancer steeply increased from 0.68/100,000 at…
DLG5 variants do not influence susceptibility to inflammatory bowel disease in the Scottish population
2005
Introduction: Recent data have suggested that specific haplotypic variants of the DLG5 gene on chromosome 10q23 may be associated with susceptibility to inflammatory bowel disease (IBD) in Germany. Haplotype D, notably characterised by the presence of a G→A substitution at nucleotide 113, was associated with susceptibility to Crohn’s disease (CD) whereas an extended haplotype A conferred protection. Aims: Association of DLG5 haplotypic variants with disease susceptibility, genotype-phenotype relationships, and epistasis with CARD15 was investigated in the Scottish population. Patients and methods: A total of 374 CD, 305 ulcerative colitis (UC), and 294 healthy controls (HC) were studied. Ge…
COVID–19. Effect of Moral Messages to Persuade the Population to Stay at Home in Spain, Chile, and Colombia
2021
1.362 / 5.000 Resultados de traducción Analizar si el contenido de tres mensajes morales (deontológico, utilitarismo ético, virtud ética) y un mensaje de control afectan diferencialmente la probabilidad de realizar cuatro comportamientos: lavarse las manos, participar en reuniones públicas, quedarse en casa/evitar el contacto social y reenviar el mensaje para informar a más personas. En nuestro estudio, el emisor del mensaje es un profesor universitario. Estas variables se miden en términos de sus intenciones de comportamiento y las intenciones de comportamiento de los demás (creencias sobre el comportamiento de los demás). Ensayo controlado aleatorizado. Nuestro estudio incluye el análisis…
Oxidative stress markers at birth: Analyses of a neonatal population
2015
In order to further understand neonatal stress and, thus, control it efficaciously, there is a need for more information on the manifestations of stress at the molecular level in the newborn, with particular regard to oxidants, and anti-oxidant and anti-stress mechanisms, including mitochondrial heat shock protein-chaperones such as Hsp60. We investigated patterns of anti-oxidants, biomarkers of oxidative stress, and Hsp60 levels in sera from newborns and found significant associations between glutathione (GSH) levels and gestational age, delivery modality, and lipid hydroperoxydes (LOOH) level. LOOH levels and spontaneous (vaginal) delivery were independently associated with increased GSH …
Inverse Effects of Midlife Occupational and Leisure Time Physical Activity on Mobility Limitation in Old Age-A 28-Year Prospective Follow-Up Study
2014
Objectives: To evaluate in a sample of initially middle-aged municipal employees whether leisure time (LPA) or occupational physical activity (OPA) was associated with mobility limitation (ML) in old age. Design: Prospective population-based follow-up. Setting: Municipalities in Finland. Participants: Public sector employees from the Finnish Longitudinal Study on Municipal Employees (FLAME) initially aged 44 to 58 (N = 5,200). Measurements: Baseline data were collected in 1981, including LPA (average exercise within previous year: inactive (no exercise), moderate (some form of exercise ?1 time per week), vigorous (brisk exercise ?1 time per week)) and OPA (usual activities at work within pr…
