A Case–Control Study of Lung Cancer Nested in a Cohort of European Asphalt Workers

BACKGROUND: We conducted a nested case-control study in a cohort of European asphalt workers in which an increase in lung cancer risk has been reported among workers exposed to airborne bitumen fume, although potential bias and confounding were not fully addressed. OBJECTIVE: We investigated the contribution of exposure to bitumen, other occupational agents, and tobacco smoking to the risk of lung cancer among asphalt workers. METHODS: Cases were cohort members in Denmark, Finland, France, Germany, the Netherlands, Norway, and Israel who had died of lung cancer between 1980 and the end of follow-up (2002-2005). Controls were individually matched in a 3:1 ratio to cases on year of birth and country. We derived exposure estimates for bitumen fume and condensate, organic vapor, and polycyclic aromatic hydrocarbons, as well as for asbestos, crystalline silica, diesel motor exhaust, and coal tar. Odds ratios (ORs) were calculated for ever-exposure, duration, average exposure, and cumulative exposure after adjusting for tobacco smoking and exposure to coal tar. RESULTS: A total of 433 cases and 1,253 controls were included in the analysis. The OR was 1.12 [95% confidence interval (CI), 0.84-1.49] for inhalation exposure to bitumen fume and 1.17 (95% CI, 0.88-1.56) for dermal exposure to bitumen condensate. No significant trend was observed between lung cancer risk and duration, average exposure, or cumulative exposure to bitumen fume or condensate. CONCLUSIONS: We found no consistent evidence of an association between indicators of either inhalation or dermal exposure to bitumen and lung cancer risk. A sizable proportion of the excess mortality from lung cancer relative to the general population observed in the earlier cohort phase is likely attributable to high tobacco consumption and possibly to coal tar exposure, whereas other occupational agents do not appear to play an important role

"Che tempo fa?" Indagine sul grado di Soddisfazione dei servizi offerti dal Centro Basaglia: l'opinione dei pazienti.

Studio costituito da una prima parte nella quale viene presentata l’evoluzione storica del Sistema Sanitario Nazionale italiano presentando successivamente i piani sanitari odierni in materia di salute mentale; l’importanza della valutazione della soddisfazione del servizio in salute mentale per migliorare la qualità di vita degli utenti apprendendo l’evoluzione dello stesso concetto e della sua importanza. Nella seconda parte della tesi verrà descritto nello specifico la rete dei servizi nel settore della salute mentale svolte sul territorio pisano con un attenzione particolare al Centro Basaglia, luogo in cui è stato possibile raccogliere i dati a testimonianza di tale ricerca

The use of antidepressant medication in Parkinson's disease patients is not affected by the type of antiparkinson medication.

Previous studies have suggested that dopamine agonists have an antidepressant effect in Parkinson's disease (PD) patients. We examined whether fewer PD patients used antidepressant medication, when they were first treated with a dopamine agonist compared to other PD medications. PD patients diagnosed in Denmark were identified, and the diagnosis was confirmed by a review of the medical record. Antidepressant medication was assessed using the Danish National Prescription Registry. We used Cox proportional hazards regression to model the association between PD medications and time to antidepressant prescription. The type of PD medication first prescribed did not affect the subsequent use of antidepressants

Traffic-related air pollution and Parkinson’s disease in Denmark: A case-control study

[[abstract]]Background: Very little is currently known about air pollutants' adverse effects on neurodegenerative diseases even though recent studies have linked particulate exposures to brain pathologies associated with Parkinson's and Alzheimer's disease. Objective: In the present study, we investigated long-term exposure to traffic-related air pollution and Parkinson's disease. Methods: In a case-control study of 1,696 Parkinson's disease (PD) patients identified from Danish hospital registries and diagnosed 1996-2009 and 1,800 population controls matched by sex and year of birth, we assessed long-term traffic-related air pollutant exposures (represented by nitrogen dioxide; NO2) from a dispersion model, using residential addresses from 1971 to the date of diagnosis or first cardinal symptom for cases and the corresponding index date for their matched controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated with logistic regression, adjusting for matching factors and potential confounders. Results: We found ambient air pollution from traffic sources to be associated with risk of PD, with a 9% higher risk (95% CI: 3, 16.0%) per interquartile range increase (2.97 μg/m(3)) in modeled NO2. For participants living for ≥ 20 years in the capital city, ORs were larger (OR = 1.21; 95% CI: 1.11, 1.31) than in provincial towns (OR = 1.10; 95% CI: 0.97, 1.26), whereas there was no association among rural residents. Conclusions: Our findings raise concerns about potential effects of air pollution from traffic and other sources on the risk of PD, particularly in populations with high or increasing exposures
