Job strain as a risk factor for coronary heart disease:a collaborative meta-analysis of individual participant data

BACKGROUND: Published work assessing psychosocial stress (job strain) as a risk factor for coronary heart disease is inconsistent and subject to publication bias and reverse causation bias. We analysed the relation between job strain and coronary heart disease with a meta-analysis of published and unpublished studies. METHODS: We used individual records from 13 European cohort studies (1985-2006) of men and women without coronary heart disease who were employed at time of baseline assessment. We measured job strain with questions from validated job-content and demand-control questionnaires. We extracted data in two stages such that acquisition and harmonisation of job strain measure and covariables occurred before linkage to records for coronary heart disease. We defined incident coronary heart disease as the first non-fatal myocardial infarction or coronary death. FINDINGS: 30?214 (15%) of 197?473 participants reported job strain. In 1·49 million person-years at risk (mean follow-up 7·5 years [SD 1·7]), we recorded 2358 events of incident coronary heart disease. After adjustment for sex and age, the hazard ratio for job strain versus no job strain was 1·23 (95% CI 1·10-1·37). This effect estimate was higher in published (1·43, 1·15-1·77) than unpublished (1·16, 1·02-1·32) studies. Hazard ratios were likewise raised in analyses addressing reverse causality by exclusion of events of coronary heart disease that occurred in the first 3 years (1·31, 1·15-1·48) and 5 years (1·30, 1·13-1·50) of follow-up. We noted an association between job strain and coronary heart disease for sex, age groups, socioeconomic strata, and region, and after adjustments for socioeconomic status, and lifestyle and conventional risk factors. The population attributable risk for job strain was 3·4%. INTERPRETATION: Our findings suggest that prevention of workplace stress might decrease disease incidence; however, this strategy would have a much smaller effect than would tackling of standard risk factors, such as smoking.

Stereotactic radiosurgery for arteriovenous malformations, Part 1:management of Spetzler-Martin Grade I and II arteriovenous malformations

The aim of this paper was to define the outcomes and risks of stereotactic radiosurgery (SRS) for Spetzler-Martin Grade I and II arteriovenous malformations (AVMs).

Preparation of Dess-Martin periodinane - The role of the morphology of 1-hydroxy-1,2-benziodoxol-3(1H)-one 1-oxide precursor

1-Hydroxy-1,2-benziodoxol-3(1H)-one I-oxide prepared by oxidation of o-iodobenzoic acid with potassium bromate forms either a microcrystalline powder, a macrocrystalline material, or a mixture of both forms. This difference in physical form is the source of the difficulty in reproducibly converting 1-hydroxy-1,2-benziodoxol-3(1H)-one 1-oxide to the corresponding I-triacetoxy derivative. A simple method is given for conversion of crystalline 1-hydroxy-1,2-benziodoxol-3(1H)-one 1-oxide to the more reactive powder form, The microcrystalline powder and macrocrystalline material are characterised by X-ray diffraction.

Dos décadas de una atormentada relación: Martin Heidegger y Edmund Husserl 1909-1929

La publicación reciente de documentos y la consulta directa en archivos posibilita un acercamiento renovado a la conflictiva relación entre Edmund Husserl y Martin Heidegger. El artículo lleva a cabo esto mediante una revisión del camino académico de Heidegger a la sombra de su protector Husserl. De ese modo se dejan ver las escisiones anímicas del joven Heidegger, su apropiación de la fenomenología husserliana y a la vez su distanciamiento del maestro. Con ello también se muestra que el rompimiento entre ambos pensadores no tiene su origen en los compromisos políticos de Heidegger en 1933, sino que era algo que latía desde el inicio de la relación.
