ABSTRACT
BACKGROUND: Literature has shown that work maintenance is central in order to guarantee participation to persons with disability. Knowledge about potential sources of difficulties and obstacles is then crucial in order to prevent barriers and facilitate work maintenance and career development for persons with disabilities. OBJECTIVE: Studies analyzing on-the-job barriers among employed people with multiple sclerosis (MS) have found evidence for a role of clinical determinants. The aim of this study was to describe in more detail the role of disability severity and of cognitive indices on work barriers. PARTICIPANTS: Thirty-two employed adults with a diagnosis of MS with mild to moderate disability severity were included in the study. They were involved in the descriptive study while attending their planned care in the MS unit. METHODS: Subjects completed neurocognitive tasks, a self-report measure of executive functioning and a face-to-face semi-structured interview exploring their perception of barriers at work. RESULTS: Regression analyses showed a specific role of disability severity on perception of barriers due to physical, cognitive and interpersonal relationships; cognitive indices, on the other hand, predicted barriers ascribed to company policy (cognitive score), to accessibility (planning score) or difficulties in cognitive and task related abilities (self-rated executive functioning). CONCLUSION: These findings underline the relevance of objective tasks and self-report questionnaire, direct and indirect multi-dimensional assessment of functioning for an early intervention planning. An ecological model of career development in adults with disabilities is also supported.

Homocysteine increases in the acute phase of ischaemic stroke and from the acute to the convalescent phase, suggesting that hyper-homocysteinaemia may be a consequence rather than a causal factor. Therefore we measured homocysteine plasma levels in stroke patients in order to investigate possible correlations of homocysteine with stroke severity and clinical outcome. Further we looked for eventual differences in stroke subtypes. We prospectively studied plasma homocysteine levels in acute stroke patients admitted to the stroke unit of our department. Seven hundred and seventy-five ischaemic stroke patients, 39 cerebral haemorrhages and 421 healthy control subjects have been enrolled. Stroke severity and clinical outcome were measured with the Scandinavian Stroke Scale, the Rankin Scale and the Barthel Index. Stroke severity by linear stepwise regression analysis was not an independent determinant of plasma homocysteine levels. Homocysteine was not correlated with outcome measured by the Barthel Index. Mean plasma homocysteine of both ischaemic and haemorrhagic stroke was significantly higher than controls (p<0.05). Homocysteine had an adjusted odds ratios (OR) of 4.2 (95% CI 2.77-6.54) for ischaemic stroke and of 3.69 (95% CI 1.90-7.17) for haemorrhagic stroke. Compared with the lowest quartile, the upper quartile was associated with an adjusted OR of ischaemic stroke due to small artery disease of 17.4 (95% CI 6.8-44.3). Homocysteine in the acute phase of stroke was not associated with stroke severity or outcome. Elevated plasma homocysteine in the acute phase of stroke was associated with both ischaemic and haemorrhagic stroke. Higher levels are associated with higher risk of small artery disease subtype of stroke.

We investigated the prevalence of dementia and the apolipoprotein E (APOE) genotype distribution in the elderly of Buttapietra, a village near Verona, Italy. All residents over the age of 74 (n = 238), including those who were institutionalized, were studied using a direct-contact, single-phase design. The overall prevalence of dementia, clinically defined by DSM-III-R criteria, was 15.8 cases per 100 population, with age-specific figures increasing steeply with advancing age in both sexes. Alzheimer's disease (AD) was the most frequent dementing disorder (43%). APOE genotyping was determined after DNA amplification by restriction isotyping. We found that the epsilon4 allele and the epsilon3/epsilon4 genotype were associated with all types of dementia, although only the association of epsilon3/epsilon4 with AD reached statistical significance (odds ratio 4.5, 95% confidence interval 1.3-16.1). However, as reported in other Mediterranean countries, the frequency of the epsilon4 allele in our population was low (8.9%), suggesting that the population-attributable risk for AD, at least for elderly individuals (> or =75 years), could be small.

We conducted a study on the factors predictive of early mortality (within 30 days of onset of symptoms) in a clinical series of 94 patients at their first stroke. Irrespective of the type of stroke, ischemic or hemorrhagic, early mortality proved to correlate with clinical parameters, such as coma at onset, presence of paralysis, changes in ocular motility, and neuroradiological parameters (lesion size on the CT scan) indicative of stroke severity.
