Social inequalities in breast cancer mortality among French women: disappearing educational disparities from 1968 to 1996
We investigated the time trends in social inequalities in breast cancer mortality with an analysis by age at death and birth cohort using a representative 1% sample of the French population and four subcohorts (1968–1974, 1975–1981, 1982–1988 and 1990–1996). Causes of death were obtained by direct linkage with the French national death registry. Education was measured at the beginning of each period, and educational disparities in breast cancer mortality were studied among women aged 35–74 at the beginning of each period. In the 1970s, higher breast cancer mortality was found among higher educated women. This positive association progressively weakened and no association remained in the 1990s although it disappeared earlier among younger women. In an analysis by birth cohort, the same pattern was found among women born before 1925, whereas no association between education and mortality was observed among women born after 1925. Educational disparities in breast cancer mortality are currently changing and the previously observed positive gradient has disappeared. An important question is whether these relations are indirect, and due to changes in the prevalence of risk factors associated with education, but which we could not study
Job strain as a risk factor for clinical depression : systematic review and meta-analysis with additional individual participant data
Background. Adverse psychosocial working environments characterized by job strain (the combination of high demands and low control at work) are associated with an increased risk of depressive symptoms among employees, but evidence on clinically diagnosed depression is scarce. We examined job strain as a risk factor for clinical depression. Method. We identified published cohort studies from a systematic literature search in PubMed and PsycNET and obtained 14 cohort studies with unpublished individual-level data from the Individual-Participant-Data Meta-analysis in Working Populations (IPD-Work) Consortium. Summary estimates of the association were obtained using random-effects models. Individual-level data analyses were based on a pre-published study protocol. Results. We included six published studies with a total of 27 461 individuals and 914 incident cases of clinical depression. From unpublished datasets we included 120 221 individuals and 982 first episodes of hospital-treated clinical depression. Job strain was associated with an increased risk of clinical depression in both published [relative risk (RR) = 1.77, 95% confidence interval (CI) 1.47-2.13] and unpublished datasets (RR = 1.27, 95% CI 1.04-1.55). Further individual participant analyses showed a similar association across sociodemographic subgroups and after excluding individuals with baseline somatic disease. The association was unchanged when excluding individuals with baseline depressive symptoms (RR = 1.25, 95% CI 0.94-1.65), but attenuated on adjustment for a continuous depressive symptoms score (RR = 1.03, 95% CI 0.81-1.32). Conclusions. Job strain may precipitate clinical depression among employees. Future intervention studies should test whether job strain is a modifiable risk factor for depression.Peer reviewe
Low back pain around retirement age and physical occupational exposure during working life
<p>Abstract</p> <p>Background</p> <p>Physical occupational exposure is a risk factor for low back pain in workers but the long term effects of exposure remain unclear. As several countries consider increasing the retirement age, further information on this topic is relevant. This study aimed to describe the prevalence of low back pain among middle aged and aging individuals in the general French population according to physical occupational exposure and retirement status.</p> <p>Methods</p> <p>The study population originated from the French national survey 'Enquête décennale santé 2002'. Low back pain for more than 30 days within the previous twelve months (LBP) was assessed using a French version of the Nordic questionnaire. Occupational exposure was self assessed. Subjects were classified as "exposed" if they were currently or had previously been exposed to handling of heavy loads and/or to tiring postures. The weighted prevalence of LBP was computed separately for men and women, for active (aged 45-59) and retiree (aged 55-74), according to 5-year age group and past/present occupational exposure.</p> <p>Results</p> <p>For active men, the prevalence of LBP was significantly higher in those currently or previously exposed (n = 1051) compared with those never exposed (n = 1183), respectively over 20% versus less than 11%. Among retired men, the prevalence of LBP tended towards equivalence with increasing age among those previously exposed (n = 748) and those unexposed (n = 599).</p> <p>Patterns were quite similar for women with a higher prevalence in exposed active women (n = 741) compared to unexposed (n = 1260): around 25% versus 15%. Similarly, differences between previously exposed (n = 430) and unexposed (n = 489) retired women tended to reduce with age.</p> <p>Conclusion</p> <p>The prevalence of LBP in active workers was associated with occupational exposure. The link with past exposure among retirees decreased with age. These results should be considered for policies dealing with prevention at the workplace and retirement.</p
The role of sulfoglucuronosyl glycosphingolipids in the pathogenesis of monoclonal IgM paraproteinemia and peripheral neuropathy
In IgM paraproteinemia and peripheral neuropathy, IgM M-protein secretion by B cells leads to a T helper cell response, suggesting that it is antibody-mediated autoimmune disease involving carbohydrate epitopes in myelin sheaths. An immune response against sulfoglucuronosyl glycosphingolipids (SGGLs) is presumed to participate in demyelination or axonal degeneration in the peripheral nervous system (PNS). SGGLs contain a 3-sulfoglucuronic acid residue that interacts with anti-myelin-associated glycoprotein (MAG) and the monoclonal antibody anti-HNK-1. Immunization of animals with sulfoglucuronosyl paragloboside (SGPG) induced anti-SGPG antibodies and sensory neuropathy, which closely resembles the human disease. These animal models might help to understand the disease mechanism and lead to more specific therapeutic strategies. In an in vitro study, destruction or malfunction of the blood-nerve barrier (BNB) was found, resulting in the leakage of circulating antibodies into the PNS parenchyma, which may be considered as the initial key step for development of disease
Job strain as a risk factor for clinical depression: systematic review and meta-analysis with additional individual participant data
Splenic artery embolization: technically feasible but not necessarily advantageous.
The spleen is the second most commonly injured organ in cases of abdominal trauma. Management of splenic injury depends on the clinical status of the patient and can include nonoperative management (NOM), splenic artery embolization (SAE), surgery (operative splenic salvage or splenectomy), or a combination of these treatments. In nonoperatively managed cases, SAE is sometimes used to control haemorrhage. However, the indications for SAE have not been clearly defined and, in some cases, the potential complications of the procedure may outweigh its benefits.This article is freely available via Open Access.

Évolution des comportements et indicateurs de santé mentale entre 2006 et 2010 dans la population au travail en France
International audienceBackground: The 2008 economic crisis may have had an impact on mental health but the studies on this topic are sparse, in particular among the working population. However, mental health at work is a crucial issue involving substantial costs and consequences. The aim of the study was to assess changes in behaviors and indicators of mental health in the French working population between 2006 and 2010, and to explore the differential changes according to age, origin, occupation, activity sector, public/private sector, self-employed/employee status and work contract.Methods: The data came from the prospective national representative Santé et itinéraire professionnel (SIP) survey, including a sample of 5600 French workers interviewed in 2006 and 2010. The behaviors and indicators of mental health studied were excessive alcohol consumption, smoking, sleep problems (sleep disorders and/or insufficient sleep duration), psychotropic drug use (antidepressants, anxiolytics and/or hypnotics), and poor self-reported health. Generalized estimating equations were used to analyze changes in behaviors and indicators of mental health, and the analyses were adjusted for age. Covariates (age, origin, occupation, activity sector, public/private sector, self-employed/employee status and type of contract) were added separately to assess differential changes.Results: Increases in excessive alcohol consumption among women, sleep problems among men, and smoking, insufficient sleep duration and poor self-reported health for both genders were observed in the French working population between 2006 and 2010. Some differential changes were observed, negative changes being more likely to affect young workers and workers with a permanent contract.Position du problème: Les répercussions de la crise économique de 2008 sur la santé mentale de la population sont encore mal connues, en particulier dans la population au travail. Pourtant la santé mentale au travail est un enjeu important par ses coûts et ses conséquences substantiels. L’objectif était d’évaluer l’évolution de la prévalence de comportements et d’indicateurs de santé mentale dans la population au travail en France entre 2006 et 2010, et d’étudier les évolutions différentielles selon l’âge, l’origine, la profession, le secteur d’activité, le secteur public/privé, le statut indépendant/salarié et le type de contrat.Méthodes: L’enquête Santé et itinéraire professionnel (SIP) est une enquête prospective représentative de la population générale française, et parmi les individus interrogés, 5600 étaient en emploi en 2006 et en 2010. Les comportements et les indicateurs de santé mentale étudiés étaient la consommation d’alcool à risque, le tabagisme, les problèmes du sommeil (troubles du sommeil et/ou durée de sommeil insuffisante), la prise de psychotropes (antidépresseurs, anxiolytiques et/ou hypnotiques), et la mauvaise santé perçue. Des équations d’estimation généralisées ont été utilisées pour étudier les évolutions, les analyses étaient ajustées sur l’âge, puis des covariables (âge, origine, profession, secteur d’activité, secteur public/privé, statut indépendant/salarié et type de contrat) ont été introduites séparément pour évaluer les évolutions différentielles.Résultats: Dans la population au travail en France, des augmentations de la prévalence de la consommation d’alcool à risque chez les femmes, des problèmes de sommeil chez les hommes, et de tabagisme, de la durée de sommeil insuffisante et de la mauvaise santé perçue pour les deux genres ont été observées entre 2006 et 2010. Quelques évolutions différentielles ont été mises en évidence, en particulier au détriment des plus jeunes et des personnes en contrat permanent.Conclusion: En conclusion, les politiques de prévention devraient considérer que les prévalences des comportements et des indicateurs de mauvaise santé mentale peuvent avoir augmenté en période de crise économique, en particulier pour certains sous-groupes de la population au travail tels que les plus jeunes et les personnes en contrat permanent. Ces évolutions pourraient laisser présager une augmentation future des pathologies mentales

Classic and emergent psychosocial work factors and mental health
International audienceBackground Little is known about associations between emergent psychosocial work factors and mental health.Aims To explore associations between classical and emergent psychosocial work factors and depression and anxiety symptoms in employees in France.Methods A national cross-sectional study (the SUrveillance Médicale des Expositions aux Risques professionnels (SUMER) survey) assessed psychosocial work factors including psychological demands, decision latitude, social support, reward and its sub-dimensions (esteem, job security and job promotion), bullying, verbal abuse, physical violence and sexual assault, long working hours, shift and night work, unsociable work days, predictability and demands for responsibility. We also measured depression and anxiety symptoms using the Hospital Anxiety and Depression scale. We used gender-stratified generalized linear models to adjust for age, occupation and economic activity.Results A total of 26883 men and 20079 women participated (response rate 87%). Low decision latitude, high psychological demands, low social support, low reward, bullying and verbal abuse were associated with depression and anxiety in both genders (β coefficients from 0.14 to 1.40). In men, low predictability was associated with both depression and anxiety (β = 0.12 [95% confidence interval (CI) 0.01, 0.24] and 0.19 [95% CI 0.06, 0.32]) and long working hours were associated with anxiety (β = 0.48 [95% CI 0.27, 0.69]). The strongest associations were observed for bullying, reward (especially esteem) and psychological demands. Using a less conservative approach, we found more factors to be significantly associated with mental health symptoms.Conclusions Most psychosocial work factors studied are associated with depression and/or anxiety symptoms. Comprehensive prevention policies may help to reduce exposure to psychosocial work factors, including emergent ones, and improve mental health at work
