    We aimed to estimate rates, causes and risk factors of all-cause mortality in a large population-based cohort of multiple sclerosis (MS) patients compared with patients without MS. Using data from the UK General Practice Research Database, we identified MS cases diagnosed during 2001–2006 and validated using patients’ original records where possible. We also included MS cases during 1993–2000 identified and validated in an earlier study. Cases were matched to up to ten referents without MS by age, sex, index date (date of first MS diagnosis for cases and equivalent reference date for controls), general practice and length of medical history before first MS diagnosis. Patients were followed up to identify deaths; hazard ratios (HRs) and 95 % confidence intervals (CIs) were estimated using Cox-proportional regression. MS patients (N = 1,822) had a significantly increased risk of all-cause mortality compared with referents (N = 18,211); adjusted HR 1.7 (95 % CI 1.4–2.1). Compared with referents, female MS patients had a higher but not significantly different HR for death than males; adjusted HR 1.86 (95 % CI 1.46–2.38) vs. HR 1.31 (95 % CI 0.93–1.84), respectively. The most commonly recorded cause of death in MS patients was ‘MS’ (41 %), with a higher proportion recorded among younger patients. A significantly higher proportion of referents than MS patients had cancer recorded as cause of death (40 vs. 19 %). Patients with MS have a significant 1.7-fold increased risk of all-cause mortality compared with the general population. MS is the most commonly recorded cause of death among MS patients.

    Investigated the association between cognitive status and adjustment in children who have a physical disability, in three independent studies. In Study 1, 119 mothers reported on the cognitive status and behavioral adjustment of their children, ages 2-18, who had varying physical or sensory impairments. In Study 2, the intellectual level of 50 children, ages 6-1 1, with either spina bifida or cerebral palsy, was estimated from cognitive test information while mothers reported on the children’s behavioral adjustment. In Study 3,66 adolescents, ages 11-18, with a physical disability completed an IQ test and reported on their behavioral adjustment, as did their mothers. Severity of physical disability was also assessed in each study. No relationships could be found between any index of cognitive status and any adjustment measure when controlling for severity of physical disability. The overwhelming majority of zero-order relationships were also not significant. These findings were discussed in relation to Wallander and Varni’s Disability- Stress-Coping model of adjustment in children with chronic physical conditions.Este artigo descreve investigag6es sobre a associação entre o estatuto cognitivo e o ajustamento em crianças com deficiĂȘncia fĂ­sica, em trĂȘs estudos independentes. No Estudo 1, 1 19 m5es prestaram informaq20 acerca do estatuto cognitivo e do ajustamento comportamental dos seus filhos, com idades entre OS 2 e OS 18 anos, e com graus variĂĄveis de deficiĂȘncia fĂ­sica ou sensorial. No Estudo 2, o nĂ­vel intelectual de 50 crianças, com idades entre OS 6 e OS 11 anos e com spina bifida ou com paralisia cerebral, foi estimado a partir de testes cognitivos e de relatos maternos sobre o seu ajustamento comportamental. No Estudo 3, 66 adolescentes, com idades entre OS 11 e OS 18 anos e com deficiĂȘncia fĂ­sica, realizaram um teste de QI e prestaram informação sobre o seu ajustamento comportamental, relato que tambĂ©m foi feito pelas suas mĂŁes. Em cada estudo, a gravidade da deficiĂȘncia fĂ­sica foi tambĂ©m avaliada. Controlando a variĂĄvel «gravidade da deficiĂȘncia fĂ­sica», nĂŁo foi possivel encontrar relação entre qualquer Ă­ndice de estatuto cognitivo e qualquer medida de ajustamento. A grande maioria de relaçÔes de ordem zero tambĂ©m nĂŁo era significativa. Estes resultados sĂŁo discutidos em função do modelo de Wallander e Varni «Disability-Stress-Coping» sobre o ajustamento em crianças com deficiĂȘncias fĂ­sicas cronicas.National Institutes of Healthinfo:eu-repo/semantics/publishedVersio

    Perceptual Pluralism

    Perceptual systems respond to proximal stimuli by forming mental representations of distal stimuli. A central goal for the philosophy of perception is to characterize the representations delivered by perceptual systems. It may be that all perceptual representations are in some way proprietarily perceptual and differ from the representational format of thought (Dretske 1981; Carey 2009; Burge 2010; Block ms.). Or it may instead be that perception and cognition always trade in the same code (Prinz 2002; Pylyshyn 2003). This paper rejects both approaches in favor of perceptual pluralism, the thesis that perception delivers a multiplicity of representational formats, some proprietary and some shared with cognition. The argument for perceptual pluralism marshals a wide array of empirical evidence in favor of iconic (i.e., image-like, analog) representations in perception as well as discursive (i.e., language-like, digital) perceptual object representations

    What factors influence training opportunities for older workers? Three factorial surveys exploring the attitudes of HR professionals

    Get PDF
    The core research questions addressed in this paper are: what factors influence HR professionals in deciding whether to approve training proposals for older workers? What kind of training are they more likely to recommend for older employees and in which organizational contexts? We administered three factorial surveys to 66 HR professionals in Italy. Participants made specific training decisions based on profiles of hypothetical older workers. Multilevel analyses indicated that access to training decreases strongly with age, while highly-skilled older employees with low absenteeism rates are more likely to enjoy training opportunities. In addition, older workers displaying positive performance are more likely to receive training than older workers who perform poorly, suggesting that training late in working life may serve as a reward for good performance rather than as a means of enhancing productivity. The older the HR professional evaluating training proposals, the higher the probability that older workers will be recommended for training. keywords: training; older workers; HR professionals; factorial survey; multilevel model

    <p>Abstract</p> <p>Background</p> <p>Symptom prevalence is generally believed to increase with age. The aim of this study was to evaluate the age specific prevalence of 30 general symptoms among Swedish middle-aged women.</p> <p>Methods</p> <p>A cross-sectional postal questionnaire study in seven Swedish counties in a random sample of 4,200 women 35–64 years old, with 2,991 responders. Thirty general symptoms included in the Complaint Score subscale of the Gothenburg Quality of Life Instrument were used.</p> <p>Results</p> <p>Four groups of age specific prevalence patterns were identified after adjustment for the influence of educational level, perceived health and mood, body mass index, smoking habits, use of hormone replacement therapy, and use of other symptom relieving therapy. Only five symptoms (insomnia, leg pain, joint pain, eye problems and impaired hearing) increased significantly with age. Eleven symptoms (general fatigue, headache, irritability, melancholy, backache, exhaustion, feels cold, cries easily, abdominal pain, dizziness, and nausea) decreased significantly with age. Two symptoms (sweating and impaired concentration) had a biphasic course with a significant increase followed by a significant decrease. The remaining twelve symptoms (difficulty in relaxing, restlessness, overweight, coughing, breathlessness, diarrhoea, chest pain, constipation, nervousness, poor appetite, weight loss, and difficulty in urinating) had stable prevalence with age.</p> <p>Conclusion</p> <p>Symptoms did not necessarily increase with age instead symptoms related to stress-tension-depression decreased.</p

    Development of parent- and teacher-reported emotional and behavioural problems in young people with intellectual disabilities: Does level of ID matter?

    This study described similarities and differences in the 5-year stability and change of problem behaviour between youths attending schools for children with mild to borderline (MiID) versus moderate intellectual disabilities (MoID). A two-wave multiple-birth-cohort sample of 6 to 18-year-old was assessed twice across a 5-year interval using the Developmental Behaviour Checklist Primary Carer version (n = 718) and Teacher version (n = 313). For most types of problem behaviour youths with MiID and MoID showed similar levels of stability of individual differences, persistence and onset of psychopathology. Whenever differences were found, youths with MoID showed the highest level of stability, persistence and onset across informants. Mean levels of parent-reported, but not teacher-reported, problem behaviour, regardless of level of intellectual disability, decreased during the 5-year follow-up period. Youths with MoID and MiID are at risk for persistent psychopathology to a similar degree. Different informants showed to have a different evaluation of the level and the amount of change of problem behaviour, and should be considered complementary in the diagnostic process. © 2007 BILD Publications
