Derivation of soil-specific streaming potential electrical parameters from hydrodynamic characteristics of partially saturated soils

Water movement in unsaturated soils gives rise to measurable electrical potential differences that are related to the flow direction and volumetric fluxes, as well as to the soil properties themselves. Laboratory and field data suggest that these so-called streaming potentials may be several orders of magnitudes larger than theoretical predictions that only consider the influence of the relative permeability and electrical conductivity on the self potential (SP) data. Recent work has improved predictions somewhat by considering how the volumetric excess charge in the pore space scales with the inverse of water saturation. We present a new theoretical approach that uses the flux-averaged excess charge, not the volumetric excess charge, to predict streaming potentials. We present relationships for how this effective excess charge varies with water saturation for typical soil properties using either the water retention or the relative permeability function. We find large differences between soil types and the predictions based on the relative permeability function display the best agreement with field data. The new relationships better explain laboratory data than previous work and allow us to predict the recorded magnitudes of the streaming potentials following a rainfall event in sandy loam, whereas previous models predict values that are three orders of magnitude too small. We suggest that the strong signals in unsaturated media can be used to gain information about fluxes (including very small ones related to film flow), but also to constrain the relative permeability function, the water retention curve, and the relative electrical conductivity function.

Characteristics of victims of violence admitted to a specialized medico-legal unit in Switzerland.

To improve care and services to victims of interpersonal violence, a medico-legal consultation unit was set up at the Lausanne University Hospital, Switzerland in 2006. Adult victims of violence are referred to the consultation by the emergency department. Patients are received by forensic nurses for support, forensic examination and community orientation. A descriptive study of medical reports filled for the 2006 population was conducted in 2007 with the aim to explore characteristics of this specific population and to better orient prevention. Among the 422 patients in 2006, 57% were men and 43% women, with a median age of 31 years old. Violent episodes took place in a public place for 90% of male victims and at home for 70% of female victims. The perpetrators were mostly unknown to male victims (62% of all men victims) and mostly known (usually the partner or a former partner) to female victims (90% of all women victims). For 80% of the women and 47% of the men, the violent event which brought them to the consultation, was not the first one. Because 90% of all patients under study were victimized by men., not only is it necessary to target prevention program to match the potential victims, prevention messages must also focus on potential offenders, especially on young men.

Real-time PCR for type-specific identification of herpes simplex in clinical samples: evaluation of type-specific results in the context of CNS diseases.

BACKGROUND: HSV-1 and HSV-2 cause CNS infections of dissimilar clinico-pathological characteristics with prognostic and therapeutic implications. OBJECTIVES: To validate a type-specific real-time PCR that uses MGB/LNA Taqman probes and to review the virologico-clinical data of 25 eligible patients with non-neonatal CNS infections. RESULTS: This real-time PCR was evaluated against conventional PCR (26 CSF and 20 quality controls), and LightCycler assay (51 mucocutaneous, 8 CSF and 32 quality controls) and culture/immunofluorescence (75 mucocutaneous) to assess typing with independent methods. Taqman real-time PCR detected 240 HSV genomes per ml CSF, a level appropriate for the management of patients, and provided unambiguous typing for the 104 positive (62 HSV-1 and 42 HSV-2) out the 160 independent clinical samples tested. HSV type diagnosed by Taqman real-time PCR predicted final diagnosis (meningitis versus encephalitis/meningoencephalitis, p<0.001) in 24/25 patients at time of presentation, in contrast to clinical evaluation. CONCLUSIONS: Our real-time PCR, as a sensitive and specific means for type-specific HSV diagnosis, provided rapid prognostic information for patient management.

Stress Perception in Public Organizations: Expanding the Job Demands - Job Resources Model by Including Public Service Motivation

Although stress has been a longstanding issue in organizations and management studies, it has never been studied in relation to Public Service Motivation. This article therefore aims to integrate PSM into the job demands-job resources model of stress in order to determine whether PSM might contribute to stress in public organizations. Drawing upon original data from a questionnaire in a Swiss municipality, this study unsurprisingly shows that "red tape" is an antecedent of stress perception, whereas satisfaction with organizational support, positive feedback, and recognition significantly decrease the level of perceived stress. Astonishingly, the empirical results show that PSM is positively and significantly related to stress perception. By increasing individuals' expectations towards their jobs, PSM might thus contribute to increased pressure on public agents. Ultimately, this article investigates the "dark side" of PSM, which has been neglected by the literature thus far.

From Leadership to Citizenship Behavior in Public Organizations: When Values Matter

After decades of management reforms in the public sector, questions on the impact of leader-ship behavior in public organizations have been attracting increasing attention. This paper investigates the relationship between transformational leadership behavior and organizational citizenship behavior as one major extra-role outcome of transformational leadership. Refer-ring to a growing body of research that shows the importance of public service values and employee identification in public administration research, we include public service motiva-tion and organizational goal clarification as mediating variables in our analysis. Structural equation modeling is applied as the method of analysis for a sample of 569 public managers at the local level of Switzerland. The findings of our study support the assumed indirect relation-ship between leadership and employee behavior and emphasize the relevance of public ser-vice values when analyzing leadership behavior in public sector organizations.

Correlation of Der p 2 T-cell responses with clinical characteristics of children allergic to house dust mite.

BACKGROUND: An understanding of the mechanisms responsible for the development and maintenance of allergic inflammation and their clinical implications is needed to develop specific and successful treatment for allergy. OBJECTIVES: To characterize in vitro T-cell responses to Der p 2, one of the major allergens of house dust mite (HDM), and investigate potential correlations between clinical and laboratory parameters. METHODS: Forty-two patients monosensitized to HDM and 10 age-matched, healthy children were studied. Dendritic cells pulsed with Der p 2 were used to stimulate autologous CD14(-) cells. Der p 2-specific T-cell activation markers, proliferation, and cytokine production profiles were examined. RESULTS: Der p 2-specific T-cell activation markers, proliferation, and T(H)2 cytokine production were significantly higher in HDM patients compared with healthy controls. Moreover, a significant correlation between proliferation and T(H)2 cytokine production was observed. Within the allergic group, skin reaction to HDM was significantly stronger in patients with a Der p 2-specific T-cell response. Levels of HDM-specific IgE directly correlated with interleukin 5 and interleukin 13 levels and with skin prick test results and, ultimately, with the patient's family history of allergy. Furthermore, the presence of atopic march correlated with T-cell proliferation. CONCLUSION: We found that, in HDM patients, Der p 2-specific T(H)2 responses, promoted by autologous dendritic cells in vitro, correlate with clinical parameters.

Alcohol-attributable mortality in Switzerland in 2011--age-specific causes of death and impact of heavy versus non-heavy drinking.

BACKGROUND: Alcohol use causes high burden of disease and injury globally. Switzerland has a high consumption of alcohol, almost twice the global average. Alcohol-attributable deaths and years of life lost in Switzerland were estimated by age and sex for the year 2011. Additionally, the impact of heavy drinking (40+grams/day for women and 60+g/day for men) was estimated. METHODS: Alcohol consumption estimates were based on the Addiction Monitoring in Switzerland study and were adjusted to per capita consumption based on sales data. Mortality data were taken from the Swiss mortality register. Methodology of the Comparative Risk Assessment for alcohol was used to estimate alcohol-attributable fractions. RESULTS: Alcohol use caused 1,600 (95% CI: 1,472 - 1,728) net deaths (1,768 deaths caused, 168 deaths prevented) among 15 to 74 year olds, corresponding to 8.7% of all deaths (men: 1,181 deaths; women: 419 deaths). Overall, 42,627 years of life (9.7%, 95% CI: 40,245 - 45,008) were lost due to alcohol. Main causes of alcohol-attributable mortality were injuries at younger ages (15-34 years), with increasing age digestive diseases (mainly liver cirrhosis) and cancers (particularly breast cancers among women). The majority (62%) of all alcohol-attributable deaths was caused by chronic heavy drinking (men: 67%; women: 48 %). CONCLUSION: Alcohol is a major cause of premature mortality in Switzerland. Its impact, among young people mainly via injuries, among men mainly through heavy drinking, calls for a mix of preventive actions targeting chronic heavy drinking, binge drinking and mean consumption.

Maternal age-specific risk of non-chromosomal anomalies.

OBJECTIVES: To determine the excess risk of non-chromosomal congenital anomaly (NCA) among teenage mothers and older mothers. DESIGN AND SETTING: Population-based prevalence study using data from EUROCAT congenital anomaly registers in 23 regions of Europe in 15 countries, covering a total of 1.75 million births from 2000 to 2004. PARTICIPANTS: A total of 38,958 cases of NCA that were live births, fetal deaths with gestational age > or = 20 weeks or terminations of pregnancy following prenatal diagnosis of a congenital anomaly. MAIN OUTCOME MEASURES: Prevalence of NCA according to maternal age, and relative risk (RR) of NCA and 84 standard NCA subgroups compared with mothers aged 25-29. RESULTS: The crude prevalence of all NCA was 26.5 per 1000 births in teenage mothers (<20 years), 23.8 for mothers 20-24 years, 22.5 for mothers 25-29 years, 21.5 for mothers 30-34 years, 21.4 for mothers 35-39 years and 22.6 for mothers 40-44 years. The RR adjusted for country for teenage mothers was 1.11 (95% CI 1.06-1.17); 0.99 (95% CI 0.96-1.02) for mothers 35-39; and 1.01 (95% CI 0.95-1.07) for mothers 40-44. The pattern of maternal age-related risk varied significantly between countries: France, Ireland and Portugal had higher RR for teenage mothers, Germany and Poland had higher RR for older mothers. The maternal age-specific RR varied for different NCAs. Teenage mothers were at a significantly greater risk (P < 0.01) of gastroschisis, maternal infection syndromes, tricuspid atresia, anencephalus, nervous system and digestive system anomalies while older mothers were at a significantly greater risk (P < 0.01) of fetal alcohol syndrome, encephalocele, oesophageal atresia and thanatophoric dwarfism. CONCLUSIONS: Clinical and public health interventions are needed to reduce environmental risk factors for NCA, giving special attention to young mothers among whom some risk factors are more prevalent. Reassurance can be given to older mothers that their age in itself does not confer extra risk for NCA.

Effects of muscle fibre shortening on the characteristics of surface motor unit potentials.

Traditionally, studies dealing with muscle shortening have concentrated on assessing its impact on conduction velocity, and to this end, electrodes have been located between the end-plate and tendon regions. Possible morphologic changes in surface motor unit potentials (MUPs) as a result of muscle shortening have not, as yet, been evaluated or characterized. Using a convolutional MUP model, we investigated the effects of muscle shortening on the shape, amplitude, and duration characteristics of MUPs for different electrode positions relative to the fibre-tendon junction and for different depths of the MU in the muscle (MU-to-electrode distance). It was found that the effects of muscle shortening on MUP morphology depended not only on whether the electrodes were between the end-plate and the tendon junction or beyond the tendon junction, but also on the specific distance to this junction. When the electrodes lie between the end-plate and tendon junction, it was found that (1) the muscle shortening effect is not important for superficial MUs, (2) the sensitivity of MUP amplitude to muscle shortening increases with MU-to-electrode distance, and (3) the amplitude of the MUP negative phase is not affected by muscle shortening. This study provides a basis for the interpretation of the changes in MUP characteristics in experiments where both physiological and geometrical aspects of the muscle are varied.

Characteristics of highly frequent users of a Swiss academic emergency department: a retrospective consecutive case series.

OBJECTIVES: The aim of this study was to describe the demographic, social and medical characteristics, and healthcare use of highly frequent users of a university hospital emergency department (ED) in Switzerland. METHODS: A retrospective consecutive case series was performed. We included all highly frequent users, defined as patients attending the ED 12 times or more within a calendar year (1 January 2009 to 31 December 2009). We collected their characteristics and calculated a score of accumulation of risk factors of vulnerability. RESULTS: Highly frequent users comprised 0.1% of ED patients, and they accounted for 0.8% of all ED attendances (23 patients, 425 attendances). Of all highly frequent users, 87% had a primary care practitioner, 82.6% were unemployed, 73.9% were socially isolated, and 60.9% had a mental health or substance use primary diagnosis. One-third had attempted suicide during study period, all of them being women. They were often admitted (24.0% of attendances), and only 8.7% were uninsured. On average, they cumulated 3.3 different risk factors of vulnerability (SD 1.4). CONCLUSION: Highly frequent users of a Swiss academic ED are a highly vulnerable population. They are in poor health and accumulate several risk factors of being even in poorer health. The small number of patients and their high level of insurance coverage make it particularly feasible to design a specific intervention to approach their needs, in close collaboration with their primary care practitioner. Elaboration of the intervention should focus on social reinsertion and risk-reduction strategies with regard to substance use, hospital admissions and suicide.

Role of CD4+CD25+ regulatory T cells in the antigen specific induction of tolerance "via" the nasal route

ABSTRACT Asthma is a complex inflammatory syndrome caused by environmental factors in predisposed individuals (atopics). Its severity correlates with the presence of activated T lymphocytes and eosinophils in the bronchoalveolar lavage fluid (BALF). Induction of tolerance via the nasal route results in reduced recruitment of eosinophils into BALF upon challenge, inhibition of TH2 pro-inflammatory cytokine secretion and T cell hyporesponsiveness. Recently, CD4+CD25+ natural regulatory T cells (Treg) were proposed as key players in controlling the development of asthma and allergic disease. The objective of the present study is to investigate the role of CD4+CD25+ regulatory T cells in the mechanisms leading to tolerance in an established model of asthma. In this goal we depleted CD4+CD25+ T cells at different times during asthma and tolerance induction protocol in mice and looked at efficiency of tolerization (intranasal application of high dose of allergen) in the absence of natural Tregs. First, ovalbumin-sensitized mice were depleted of CD25+ T cells by intraperitoneal injection of anti-CD25 mAb (PC61) either for along-term (repeated injections of anti-CD25 from day 31 until the end of the protocol) or a short-term period (single injection of anti-CD25 before or after tolerance induction). We demonstrated that the long-term depletion of CD4+CD25+ T cells severely hampered tolerance induction (marked enhancement in eosinophil recruitment into BALF and a vigorous antigen specific T cell response to OVA upon allergen challenge) whereas transient depletions were not sufficient to do so. We then characterized T cell subsets by flow cytometry and observed that a large part of CD4+CD25+ T cells express Foxp3, an established marker of regulatory T cells. We also tested in-vitro suppressor activity of CD4+CD25+ T cells from tolerized mice by cell proliferation assay in coculture and observed a strong suppressive activity. Our data suggest that CD4+CD25+ T cells with regulatory properties play a crucial role in the induction of tolerance via the nasal route. The relationship between CD25+ natural Treg and inducible IL-10+ TRl-type Treg will have to be defined. RESUME L'asthme est un syndrome inflammatoire complexe provoqué par des facteurs environnementaux chez des individus génétiquement prédisposés (atopiques). Sa sévérité corrèle avec la présence des lymphocytes T activés et d'éosinophiles dans le lavage bronchoalvéolaire (BAL). L'induction de la tolérance par la voie nasale résulte en une diminution du recrutement des eosinophils dans le BAL, une inhibition de la sécrétion de cytokines pro-inflammatoires de type TH2 et de l'hypo-réponse des cellules T à l'allergène. Récemment, les cellules régulatrices «naturelles » de type CD4+CD25+ T (Tregs) ont été proposées comme acteurs essentiels dans le développement de l'asthme et de l'allergie. L'objectif de cette étude est d'étudier le rôle des cellules régulatrices CD4+CD25+ T dans les mécanismes menant à la tolérance dans un modèle établi d'asthme. Dans ce but nous avons déplété les cellules de CD4+CD25+ T à différents temps au cours du protocole d'induction d'asthme et de tolérance et nous avons regardé l'efficacité de l'induction de tolérance (application intranasale d'une dose importante d'allergène) en l'absence de Tregs. Dans un premier temps des souris sensibilisées à l'ovalbumine (OVA) ont été déplétées en cellules CD25+ T par l'injection intrapéritonéale d'anti-CD25 mAb (PC61) pour une longue période (injections répétées d'anti-CD25 du jour 31 jusqu'à la fin du protocole) ou pour une courte période (injection unique d'anti-CD25 avant ou après l'induction de tolérance). Nous avons démontré que la déplétion à long t erme des cellules de CD4+CD25+ T a empêché l'induction de tolérance (recrutement accru d'éosinophiles dans le BAL et une réponse vigoureuse des cellules T spécifiques de l'antigène après exposition à l'allergène) tandis des déplétions à court-terme n'ont pas cet effet. Nous avons ensuite caractérisé des sous-populations de cellules T par cytométrie de flux. Nous avons observé que la majorité des cellules CD4+CD25+ T expriment Foxp3, un marqueur établi des cellules régulatrices. Nous avons également examiné in vitro l'activité régulatrice des cellules T CD4+CD25+ issues de souris tolérisées. La prolifération de cellules T en coculture a démontré une forte activité suppressive des cellules CD4+CD25+. Nos données suggèrent que des cellules T CD4+CD25+ ayant des propriétés régulatrices jouent un rôle crucial dans l'induction de la tolérance par la voie nasale. Le rapport entre les cellules régulatrices naturelles CD4+CD25+ et les cellules régulatrices inductible de type TR1 I1-10+ devra être défini. RESUME DESTINE A UN LARGE PUBLIC L'asthme est une maladie inflammatoire des bronches, caractérisée par des crises de dyspnée (gêne respiratoire) témoignant d'une activation brutale des muscles bronchoconstricteurs, auxquelles s'associent un oedème et une hypersécrétion des muqueuses des voies aériennes ainsi qu'une importante production d'anticorps de l'allergie (IgE). Chez la plupart des enfants atteints et chez près de la moitié des adultes concernés par l'asthme, c'est une allergie à des substances présentes dans l'air environnant (acariens, pollens ou poils d'animaux) qui est à l'origine de la maladie. . Le traitement actuel de l'asthme repose d'une part sur le soulagement des symptômes grâce à des produits à base de stéroïdes ou des bronchodilatateurs. D'autre part, l'immunothérapie spécifique (aussi appelée désensibilisation) permet d'améliorer l'asthme et de «reprogrammer» le système immunitaire. C'est à ce jour, le seul moyen connu de faire régresser une allergie. Cependant l'immunothérapie prend beaucoup de temps (3 à 5 ans) et ne marche pas à tous les coups ni pour tous les antigènes. Il est donc important de mieux comprendre les mécanismes impliqués lors d'un tel traitement afin d'en améliorer l'efficacité. Af n de pouvoir investiguer en détail ces mécanismes des modèles d'immunothérapie ont été mis au point chez la souris. Notre étude se base sur un modèle d'asthme allergique chez la souris. Des souris sont rendues allergiques à l'ovalbumine (OVA) et présentent alors les caractéristiques majeures de l'asthme humain (recrutement de cellules inflammatoires dans les poumons, augmentation de la production d'IgE et de la résistance des bronches aux flux respiratoires). Ces souris asthmatiques une fois traitées par l'application nasale d'OVA (forme d'immunothérapie muqueuse) ne développent plus de réaction allergique lors d'une ré-exposition à l'allergène. Notre hypothèse est que cette «guérison» (tolérance) est liée à l'action de cellules (lymphocytes T CD4) dites «régulatrices» et caractérisées par le marqueur CD25. Pour le démontrer, nous avons éliminé ces cellules «régulatrices» CD25 de nos souris asthmatiques grâce à un anticorps monoclonal spécifique. Nous n'avons dès lors plus été en mesure d'induire une tolérance à l'allergène. Ceci suggère donc un rôle clé des cellules «régulatrices» T CD4+CD25+ dans la réussite de l'immunothérapie nasale dans notre modèle. Nos résultats n'excluent pas la participation d'autres cellules telles que les lymphocytes producteurs d'IL-10 (lymphocytes régulateurs induits). Le rôle respectif de ces sous-populations régulatrices devra être examiné dans les études à venir. Une meilleure maîtrise des mécanismes de régulation pourrait s'avérer cruciale pour améliorer les thérapies de l'asthme.

The PsyCoLaus study: methodology and characteristics of the sample of a population-based survey on psychiatric disorders and their association with genetic and cardiovascular risk factors.

ABSTRACT: BACKGROUND: The Psychiatric arm of the population-based CoLaus study (PsyCoLaus) is designed to: 1) establish the prevalence of threshold and subthreshold psychiatric syndromes in the 35 to 66 year-old population of the city of Lausanne (Switzerland); 2) test the validity of postulated definitions for subthreshold mood and anxiety syndromes; 3) determine the associations between psychiatric disorders, personality traits and cardiovascular diseases (CVD), 4) identify genetic variants that can modify the risk for psychiatric disorders and determine whether genetic risk factors are shared between psychiatric disorders and CVD. This paper presents the method as well as somatic and sociodemographic characteristics of the sample. METHODS: All 35 to 66 year-old persons previously selected for the population-based CoLaus survey on risk factors for CVD were asked to participate in a substudy assessing psychiatric conditions. This investigation included the Diagnostic Interview for Genetic Studies to elicit diagnostic criteria for threshold disorders according to DSM-IV and algorithmically defined subthreshold syndromes. Complementary information was gathered on potential risk and protective factors for psychiatric disorders, migraine and on the morbidity of first-degree family members, whereas the collection of DNA and plasma samples was part of the original somatic study (CoLaus). RESULTS: A total of 3,691 individuals completed the psychiatric evaluation (67% participation). The gender distribution of the sample did not differ significantly from that of the general population in the same age range. Although the youngest 5-year band of the cohort was underrepresented and the oldest 5-year band overrepresented, participants of PsyCoLaus and individuals who refused to participate revealed comparable scores on the General Health Questionnaire, a self-rating instrument completed at the somatic exam. CONCLUSIONS: Despite limitations resulting from the relatively low participation in the context of a comprehensive and time-consuming investigation, the PsyCoLaus study should significantly contribute to the current understanding of psychiatric disorders and comorbid somatic conditions by: 1) establishing the clinical relevance of specific psychiatric syndromes below the DSM-IV threshold; 2) determining comorbidity between risk factors for CVD and psychiatric disorders; 3) assessing genetic variants associated with common psychiatric disorders and 4) identifying DNA markers shared between CVD and psychiatric disorders.

Specific targeting of pro-death NMDA receptor signals with differing reliance on the NR2B PDZ ligand.

NMDA receptors (NMDARs) mediate ischemic brain damage, for which interactions between the C termini of NR2 subunits and PDZ domain proteins within the NMDAR signaling complex (NSC) are emerging therapeutic targets. However, expression of NMDARs in a non-neuronal context, lacking many NSC components, can still induce cell death. Moreover, it is unclear whether targeting the NSC will impair NMDAR-dependent prosurvival and plasticity signaling. We show that the NMDAR can promote death signaling independently of the NR2 PDZ ligand, when expressed in non-neuronal cells lacking PSD-95 and neuronal nitric oxide synthase (nNOS), key PDZ proteins that mediate neuronal NMDAR excitotoxicity. However, in a non-neuronal context, the NMDAR promotes cell death solely via c-Jun N-terminal protein kinase (JNK), whereas NMDAR-dependent cortical neuronal death is promoted by both JNK and p38. NMDAR-dependent pro-death signaling via p38 relies on neuronal context, although death signaling by JNK, triggered by mitochondrial reactive oxygen species production, does not. NMDAR-dependent p38 activation in neurons is triggered by submembranous Ca(2+), and is disrupted by NOS inhibitors and also a peptide mimicking the NR2B PDZ ligand (TAT-NR2B9c). TAT-NR2B9c reduced excitotoxic neuronal death and p38-mediated ischemic damage, without impairing an NMDAR-dependent plasticity model or prosurvival signaling to CREB or Akt. TAT-NR2B9c did not inhibit JNK activation, and synergized with JNK inhibitors to ameliorate severe excitotoxic neuronal loss in vitro and ischemic cortical damage in vivo. Thus, NMDAR-activated signals comprise pro-death pathways with differing requirements for PDZ protein interactions. These signals are amenable to selective inhibition, while sparing synaptic plasticity and prosurvival signaling.

Clinical and course characteristics of depression and all-cause mortality: A prospective population-based study.

BACKGROUND: Given the large heterogeneity of depressive disorders (DD), studying depression characteristics according to clinical manifestations and course is a more promising approach than studying depression as a whole. The purpose of this study was to determine the association between clinical and course characteristics of DD and incident all-cause mortality. METHODS: CoLaus|PsyCoLaus is a prospective cohort study (mean follow-up duration=5.2 years) including 35-66 year-old randomly selected residents of an urban area in Switzerland. A total of 3668 subjects (mean age 50.9 years, 53.0% women) underwent physical and psychiatric baseline evaluations and had a known vital status at follow-up (98.8% of the baseline sample). Clinical (diagnostic severity, atypical features) and course characteristics (recency, recurrence, duration, onset) of DD according to the DSM-5 were elicited using a semi-structured interview. RESULTS: Compared to participants who had never experienced DD, participants with current but not remitted DD were more than three times as likely to die (Hazard Ratio: 3.2, 95% CI: 1.1-10.0) after adjustment for socio-demographic and lifestyle characteristics, comorbid anxiety disorders, antidepressant use, and cardiovascular risk factors and diseases. There was no evidence for associations between other depression characteristics and all-cause mortality. LIMITATIONS: The small proportion of deceased subjects impeded statistical analyses of cause-specific mortality. CONCLUSIONS: A current but not remitted DD is a strong predictor of all-cause mortality, independently of cardiovascular or lifestyle factors, which suggests that the effect of depression on mortality diminishes after remission and further emphasizes the need to adequately treat current depressive episodes.
