RESUMO

BACKGROUND: The association of depression with mortality and the significance of explanatory factors, in particularly gender, have remained an issue of debate. We therefore aimed to estimate the effect of depression on all-cause mortality, to examine potential explanatory factors and to assess effect modification by gender. METHODS: We used Cox regression models to estimate the effect of depression on mortality based on data from the Gutenberg Health Study, which is a prospective cohort study of the adult population in the districts of Mainz and Mainz-Bingen, Germany. Baseline assessment was between 2007 and 2012. Effect modification by gender was measured on both additive and multiplicative scales. RESULTS: Out of 14,653 participants, 7.7% were depressed according to Patient Health Questionnaire 9 (PHQ-9), and 1,059 (7.2%) died during a median follow-up of 10.7 years. Depression elevated the risk of mortality in men and women in age-adjusted models (HR: 1.41, 95%-CI: 1.03-1.92; resp. HR: 1.96, 95%-CI: 1.43-2.69). Adjustment for social status, physical health and lifestyle covariates attenuated the effect and in the fully-adjusted model the hazard ratio was 0.96 (95%-CI: 0.69-1.33) in men and 1.53 (95%-CI: 1.10-2.12) in women. For effect modification by gender, the measure on multiplicative interaction was 0.68 (95%-CI 0.44-1.07) and on additive interaction was RERI=-0.47 (95%-CI -1.24-0.30). LIMITATIONS: The PHQ-9 is a single self-report measure of depression reflecting symptoms of the past two weeks, limiting a more detailed assessment of depression and course of symptoms, which likely affects the association with mortality. CONCLUSIONS: Depression elevates mortality by multifactorial pathways, which should be taken into account in the biopsychosocially informed treatment of depression. Effect modification by gender was not statistically significant.

RESUMO

Nonalcoholic steatohepatitis (NASH), a chronic liver disease without an approved therapy, is associated with lipotoxicity and insulin resistance and is a major cause of cirrhosis and hepatocellular carcinoma. Aramchol, a partial inhibitor of hepatic stearoyl-CoA desaturase (SCD1) improved steatohepatitis and fibrosis in rodents and reduced steatosis in an early clinical trial. ARREST, a 52-week, double-blind, placebo-controlled, phase 2b trial randomized 247 patients with NASH (n = 101, n = 98 and n = 48 in the Aramchol 400 mg, 600 mg and placebo arms, respectively; NCT02279524 ). The primary end point was a decrease in hepatic triglycerides by magnetic resonance spectroscopy at 52 weeks with a dose of 600 mg of Aramchol. Key secondary end points included liver histology and alanine aminotransferase (ALT). Aramchol 600 mg produced a placebo-corrected decrease in liver triglycerides without meeting the prespecified significance (-3.1, 95% confidence interval (CI) -6.4 to 0.2, P = 0.066), precluding further formal statistical analysis. NASH resolution without worsening fibrosis was achieved in 16.7% (13 out of 78) of Aramchol 600 mg versus 5% (2 out of 40) of the placebo arm (odds ratio (OR) = 4.74, 95% CI = 0.99 to 22.7) and fibrosis improvement by ≥1 stage without worsening NASH in 29.5% versus 17.5% (OR = 1.88, 95% CI = 0.7 to 5.0), respectively. The placebo-corrected decrease in ALT for 600 mg was -29.1 IU l-1 (95% CI = -41.6 to -16.5). Early termination due to adverse events (AEs) was <5%, and Aramchol 600 and 400 mg were safe, well tolerated and without imbalance in serious or severe AEs between arms. Although the primary end point of a reduction in liver fat did not meet the prespecified significance level with Aramchol 600 mg, the observed safety and changes in liver histology and enzymes provide a rationale for SCD1 modulation as a promising therapy for NASH and fibrosis and are being evaluated in an ongoing phase 3 program.

RESUMO

PURPOSE: Vitamin D (VitD) is a pleiotropic hormone with effects on a multitude of systems and metabolic pathways. Consequently, the relevance of a sufficiently high VitD serum level becomes self-evident. METHODS: A rapid immunofluorescence assay designed for the point-of-care measurement of serum VitD3 solely was tested. Inter- and intra-assay validation, double testing and result comparison with a standardized laboratory method were performed. RESULTS: An overall linear correlation of r = 0.89 (Pearson, 95% CI 0.88-0.92, p < 0.01) between the point of care and the conventional reference assay was registered. Accuracy and precision were of special interest at cut-points (10 ng/ml [mean deviation 1.7 ng/ml, SD 1.98 ng/ml, SE 0.16 ng/ml], 12 ng/ml [MD 0.41, SD 1.89, SE 0.19] and 30 ng/ml [MD - 1.11, SD 3.89, SE 0.35]). Only a slight deviation was detected between the two assays when using fresh (r = 0.91, 95% CI 0.86-0.94, p < 0.01) and frozen serum samples (r = 0.86, 0.82-0.89, p < 0.01). Results remained steady when samples were frozen several times. Inter- and intra-assay validation according to the CLSI protocol as well as multiuser testing showed stable results. CONCLUSION: This novel, innovative, and controlled study indicates that the evaluated rapid point of care VitD assay is reliable, accurate, and suited for clinical practice.

RESUMO

PURPOSE: To determine the frequency of cataract surgery in Germany and to evaluate its impact on visual function in an adult population. METHODS: The population-based Gutenberg Health Study was conducted in Germany with its baseline examination between 2007 and 2012 and a 5-year follow-up examiantion. An ophthalmological examination including slit-lamp examination, ocular biometry, and Scheimpflug imaging was carried out. Overall and age-specific frequencies of unilateral and bilateral cataract surgery within 5 years were computed including the 95% confidential intervals [95%-CI]. Association analyses were conducted to determine social and ocular associated factors using multivariable logistic regression analysis. Vision-related quality of life was assessed using NEI VFQ-25. RESULTS: A total of 10,544 people aged 35 to 74 years were bilateral phakic at baseline and had information on lens status at the 5-year examination. Of these, 168 had unilateral cataract surgery (1.6% [1.4-1.9%]), and 448 had bilateral cataract surgery (4.2% [3.9-4.7%]) in the following 5 years. The frequency of cataract surgery increased with age: 45-54-year-old subjects had twice as often cataract surgery (in at least on eye: OR = 2.32) than at age 35-44 years. The frequency further strongly increases with age (55-64 years: OR = 10.5; 65-74 years: OR = 43.8, p < 0.001). Subjects with glaucoma were more likely to have cataract surgery (OR = 2.52, p < 0.001). Visual function increased when undergoing bilateral cataract surgery. CONCLUSIONS: The frequency of cataract surgery is low at younger ages and increases up to 26% at age 70-74 years. Persons with glaucoma are more likely to undergo cataract surgery at population-based level in Germany.

RESUMO

Essentials MicroRNAs (miRNAs) regulate the molecular networks controlling biological functions such as hemostasis. We utilized novel methods to analyze miRNA-mediated regulation of the hemostatic system. 52 specific miRNA interactions with 11 key hemostatic associated genes were identified. Functionality and drugability of miRNA-19b-3p against antithrombin were demonstrated in vivo. SUMMARY: Background microRNAs (miRNAs) confer robustness to complex molecular networks regulating biological functions. However, despite the involvement of miRNAs in almost all biological processes, and the importance of the hemostatic system for a multitude of actions in and beyond blood coagulation, the role of miRNAs in hemostasis is poorly defined. Objectives Here we comprehensively illuminate miRNA-mediated regulation of the hemostatic system in an unbiased manner. Methods In contrast to widely applied association studies, we used an integrative screening approach that combines functional aspects of miRNA silencing with biophysical miRNA interaction based on RNA pull-downs (miTRAP) coupled to next-generation sequencing. Results Examination of a panel of 27 hemostasis-associated gene 3'UTRs revealed the majority to possess substantial Dicer-dependent silencing capability, suggesting functional miRNA targeting. miTRAP revealed 150 specific miRNA interactions with 14 3'UTRs, of which 52, involving 40 miRNAs, were functionally confirmed. This includes cooperative miRNA regulation of key hemostatic genes comprising procoagulant (F7, F8, F11, FGA, FGG and KLKB1) and anticoagulant (SERPINA10, PROZ, SERPIND1 and SERPINC1) as well as fibrinolytic (PLG) components. Bioinformatic analysis of miRNA functionality reveals established and potential novel links between the hemostatic system and other pathologies, such as cancer, bone metabolism and renal function. Conclusions Our findings provide, along with an in-vivo proof of concept, deep insights into the network of miRNAs regulating the hemostatic system and present a foundation for biomarker discovery and novel targeted therapeutics for correction of de-regulated hemostasis and associated processes in the future. A repository of the miRNA targetome covering 14 hemostatic components is provided.

RESUMO

BACKGROUND: To investigate the prevalence of depression and anxiety among subjects with self-reported glaucoma and the association between self-reported glaucoma and depression respectively anxiety in a European cohort. METHODS: A study sample of 14,657 participants aged 35 to 74 years was investigated in a population-based cohort study. All participants reported presence or absence of glaucoma. Ophthalmological examinations were carried out in all participants and demographic and disease related information were obtained by interview. Depression was assessed with the Patient Health Questionnaire (PHQ-9), and generalized anxiety with the two screening items (GAD-2) of the short form of the GAD-7 (Generalized Anxiety Disorder-7 Scale). Prevalence of depression and generalized anxiety were investigated for subjects with and without self-reported glaucoma. Logistic regression analyses with depression, respectively anxiety as dependent variable and self-reported glaucoma as independent variable were conducted and adjusted for socio-demographic factors, systemic comorbidities (arterial hypertension, myocardial infarction, stroke, diabetes mellitus, chronic obstructive pulmonary disease, cancer), ocular diseases (cataract, macular degeneration, corneal diseases, diabetic retinopathy), visual acuity, intraocular pressure, antiglaucoma eye drops (sympathomimetics, parasympathomimetics, carbonic anhydrase inhibitors, beta-blockers, prostaglandins) and general health status. RESULTS: 293 participants (49.5% female) reported having glaucoma. Prevalence of depression among participants with and without self-reported glaucoma was 6.6% (95%-CI 4.1-10.3) respectively 7.7% (95%-CI 7.3-8.2), and for anxiety 5.3% (95%-CI 3.1-8.7) respectively 6.6% (95%-CI 6.2-7.1). Glaucoma was not associated with depression (Odds ratio 1.10, 95%-CI 0.50-2.38, p = 0.80) or anxiety (1.48, 95%-CI 0.63-3.30, p = 0.35) after adjustment for socio-demographic factors, ocular/systemic diseases, ocular parameters, antiglaucoma drugs and general health status. A restriction to self-reported glaucoma cases either taking topical antiglaucoma medications or having a history of glaucoma surgery did not alter the result. CONCLUSIONS: This is the first study analyzing both depression and anxiety among glaucoma patients in a European cohort. Subjects with and without self-reported glaucoma had a similar prevalence of depression and anxiety in our population-based sample. Self-reported glaucoma was not associated with depression or anxiety. A lack of a burden of depressive symptoms may result from recruitment from a population-based sample as compared to previous study groups predominantly recruited from tertiary care hospitals.

RESUMO

Aims: The cardiac and vascular late sequelae in long-term survivors of childhood cancer (CVSS)-study aimed to quantify the prevalence of cardiovascular risk factors (CVRF) and cardiovascular disease (CVD) in German childhood cancer survivors (CCS). Methods and results: In the CVSS-study (NCT02181049), 1002 CCS (age range 23-48 years) diagnosed with neoplasia prior to 15 years of age between 1980 and 1990 prospectively underwent a systematic, standardized clinical and laboratory cardiovascular screening, identical to the population-based Gutenberg Health Study (GHS) cohort. For 951 individuals, prevalences of CVRF and CVD were primarily compared to the GHS sample and to two further German population-based cohorts. Using log-binomial regression models, an increased risk for occurrence of arterial hypertension [relative risk (RR) 1.38, 95% confidence interval (95% CI 1.21-1.57)] and dyslipidaemia [RR 1.26 (95% CI 1.12-1.42)] was found. This indicates a premature occurrence compared to the general population of approximately 6 and 8 years, respectively [rate advancement period estimator, RAPhypertension 5.75 (95% CI 3.5-8.0) and RAPdyslipidaemia 8.16 (95% CI 4.4-11.9)]. Overall, no differences were observed for obesity and diabetes. Overt CVD was present in 4.5% (95% CI 3.0-6.6%) of CCS [RR 1.89 (95% CI 1.34-2.66), RAPCVD 7.9 (95% CI 4.1-11.7)], of which the most frequent entities were congestive heart failure and venous thromboembolism. Prevalences of CVRF and CVD increased with age without reaching a plateau over time. Conclusion: This large CCS screening examination revealed consistently in comparison to three population samples a considerably increased risk for premature CVD. The findings in these young adult CCS indicate a high burden of cardiovascular morbidity and mortality in the long term. Clinicaltrials. gov-Nr: NCT02181049.

RESUMO

Essentials The increase of cancer survival remains curtailed by cardiovascular mortality. We studied a large range of inflammatory and coagulation biomarkers in long-term cancer survivors. Cancer history has an important impact on mortality independent of cardiovascular risk factors. Fibrinogen and von Willebrand factor are potential biomarkers in survivors of increased mortality. SUMMARY: Background The advances in cancer treatment and detection of early cancer have resulted in a steady increase in the number of of cancer survivors over the years. However, because of the long-term toxic effects of chemotherapy and radiotherapy, the incidence of cardiovascular disease (CVD) is increasing in survivors. Objectives To investigate traditional cardiovascular risk factors (CVRFs), inflammation and the coagulation profile in long-term cancer survivors (cancer diagnosis ≥ 5 years) from a large adult population-based study sample. Methods The presence of cardiovascular risk factors (CVRFs) and laboratory markers were compared in individuals with (n = 723) and without (n = 13626) a long-term history of cancer from the Gutenberg Health Study. Data on coagulation factors, D-dimer and von Willebrand factor (VWF) activity were available for 4974 individuals (n = 244 cancer survivors). Results In multivariable regression models, a history of cancer was, independently of CVRFs and CVD, associated with higher fibrinogen levels (ß 6.99, 95% confidence interval [CI] 1.16-12.8), VWF activity (ß 5.08, 95% CI 0.02-10.1), and antithrombin activity (ß 1.85, 95% CI 0.44-3.27). Cancer survivors with CVD showed notably higher VWF activity than individuals with CVD without a history of cancer, with a difference in the means of 23.0 (7.9-38.1). Multivariate Cox regression analysis, adjusted for CVRFs, confirmed that a long-term history of cancer is associated with a 72% higher mortality. Increased mortality in cancer survivors was dependent on fibrinogen level and VWF activity level. Conclusion Cancer survivors showed a worse inflammation and coagulation profile than individuals without a history of cancer. Overall mortality in long-term cancer survivors was increased independently of traditional CVRFs. These results underline the need to further investigate plasma biomarkers as complementary cardiovascular risk predictors in cancer survivors.

RESUMO

In outpatient care or the emergency room laboratory tests oftentimes provide the first clues to the medical condition that made the patient seek medical help. Quite commonly, rapid medical decisions are required in these situations. Therefore, laboratory results must be evaluated immediately and interpreted within the broader context of the patient's presentation. During this process test results must be checked for plausibility, their positive and/or negative predictive values for the individual patient must be considered, and finally, the potential clinical implications need to be assessed. The latter in particular is of the utmost importance. This article discusses several laboratory tests commonly ordered for emergency patients and provides some guidance on their relevance in the decision to refer an outpatient to an emergency room or for inpatient care, or whether a patient can be safely diagnosed in the outpatient setting.

RESUMO

BACKGROUND: Major depression and anxiety disorders are known to negatively influence cognitive performance. Moreover, there is evidence for greater cognitive decline in older adults with generalized anxiety disorder. Except for clinical studies, complex executive planning functions and subclinical levels of anxiety have not been examined in a population-based sample with a broad age range. METHODS: Planning performance was assessed using the Tower of London task in a population-based sample of 4240 participants aged 40-80 years from the Gutenberg Health Study (GHS) and related to self-reported anxiety and depression by means of multiple linear regression analysis. RESULTS: Higher anxiety ratings were associated with lower planning performance (ß = -0.20; p < 0.0001) independent of age (ß = 0.03; p = 0.47). When directly comparing the predictive value of depression and anxiety on cognition, only anxiety attained significance (ß = -0.19; p = 0.0047), whereas depression did not (ß = -0.01; p = 0.71). CONCLUSIONS: Subclinical levels of anxiety but not of depression showed negative associations with cognitive functioning independent of age. Our results demonstrate that associations observed in clinical groups might differ from those in population-based samples, also with regard to the trajectory across the life span. Further studies are needed to uncover causal interrelations of anxiety and cognition, which have been proposed in the literature, in order to develop interventions aimed at reducing this negative affective state and to improve executive functioning.

RESUMO

Essentials Antiphospholipid antibodies (aPL) are heterogeneous and induce different cellular responses. We analyzed signaling events induced by different monoclonal and patient aPL in monocytes. Two major signaling pathways involving either NADPH-oxidase or LRP8 were identified. Our data suggest that these two pathways mediate the majority of aPL effects on monocytes. SUMMARY: Background Antiphospholipid antibodies (aPLs) contribute to the pathogenesis of the antiphospholipid syndrome (APS) by induction of an inflammatory and procoagulant state in different cell types, and several signaling pathways have been described. Objectives To investigate whether signaling depends on the epitope specificity of aPLs. Methods Cellular effects of three human monoclonal aPLs with distinctly different epitope specificities were analyzed in vitro. Expression of tumor necrosis factor-α mRNA by mouse and human monocytes was the major readout. Analysis included cells from genetically modified mice, and the use of specific inhibitors in human monocytes. Data were validated with IgG isolated from 20 APS patients. Results Cofactor-independent anticardiolipin aPLs activated monocytes by induction of endosomal NADPH oxidase. Activation could be blocked by hydroxychloroquine (HCQ). Anti-ß2 -glycoprotein I aPL activated monocytes by interacting with LDL receptor-related protein 8 (LRP8). This could be blocked by rapamycin. Analysis of 20 APS patients' IgG showed that all IgG fractions activated the same two pathways as the monoclonal aPL, depending on their epitope patterns as determined by ELISA. Monocyte activation by APS IgG could be blocked completely by HCQ and/or rapamycin, suggesting that in most, if not all, APS patients there is no other relevant signaling pathway. Conclusions aPLs activate two major proinflammatory signal transduction pathways, depending on their epitope specificity. HCQ and rapamycin, either alone or in combination, completely suppress signaling by APS IgG. These observations may provide a rationale for specific treatment of APS patients according to their aPL profile.

RESUMO

Essentials e-Health based health care by an expert centre may advance management of oral anticoagulation. Outcome of patients was compared between an e-health based coagulation service and regular care. Patients in the coagulation service cohort experienced a significantly better clinical outcome. Lower risk for adverse events was related to anticoagulation-specific and non-specific outcome. SUMMARY: Background Management of oral anticoagulation (OAC) therapy is essential to minimize adverse events in patients receiving vitamin K-antagonists (VKAs). Data on the effect of e-health-based anticoagulation management systems on the clinical outcome of OAC patients are limited. Objectives To compare the clinical outcome of OAC patients managed by an e-health-based coagulation service (CS) with that of patients receiving regular medical care (RMC). Methods The prospective multicenter cohort study thrombEVAL (NCT01809015) comprised 1558 individuals receiving RMC and 760 individuals managed by a CS. Independent study monitoring and adjudication of endpoints by an independent review panel were implemented. Results The primary study endpoint (composite of thromboembolism, clinically relevant bleeding and death) occurred in 15.7 per 100 patient-years (py) with RMC and in 7.0 per 100 py with the CS (rate ratio [RR], 2.3; 95% confidence interval [CI], 1.7-3.1). Rates for major and clinically relevant bleeding were higher with RMC than with the CS: 6.8 vs. 2.6 and 10.1 vs. 3.6 per 100 py, respectively. Thromboembolic events showed an RR of 1.5 (95% CI, 0.8-2.6) comparing RMC with the CS. Hospitalization (RR, 2.6; 95% CI, 2.3-3.0) and all-cause mortality (RR, 4.6; 95% CI, 2.8-7.7) were markedly more frequent with RMC. In Cox regression analysis with adjustment for age, sex, cardiovascular risk factors, comorbidities, treatment characteristics and sociodemographic status, hazard ratios (HR) for the primary endpoint (HR, 2.2; 95% CI, 1.5-3.4), clinically relevant bleeding (HR, 3.1; 95% CI, 1.7-5.5), hospitalization (HR, 2.2; 95% CI, 1.8-2.8) and all-cause mortality (HR, 5.6; 95% CI, 2.9-11.0) favored CS treatment. Conclusions In this study, e-health-based management of OAC therapy was associated with a lower frequency of OAC-specific and non-specific adverse events.

RESUMO

BACKGROUND AND AIMS: Whether single nucleotide polymorphisms (SNPs) of homocysteine metabolism enzymes influence the rate of cardiovascular (CV) events in coronary artery disease (CAD) patients remains controversial. METHODS AND RESULTS: In this analysis, 1126 subjects from the AtheroGene study with CAD and 332 control subjects without known CAD were included. The following SNPs were investigated: methylentetrahydrofolate reductase (MTHFR-C667T), methionin synthetase (MS-D919G), and cystathionin beta synthetase (CBS-I278T). The endpoint was the combination of cardiovascular death, stroke, and non-fatal myocardial infarction (N = 286). The median follow-up time was 6.4 years. Kaplan-Meier curve analysis showed an increasing event rate with rising homocysteine levels (p < 0.001) in CAD patients. Further, in Cox-Regression analysis homocysteine was a predictor of the endpoint with a hazard ratio (HR) of 6.5 (95% CI: 2.9-14.6, p < 0.001) in the adjusted model including cardiovascular risk factors. Of the three SNPs, homozygous MTHFR SNP increased homocysteine levels significantly in patients with CAD and individuals without CAD (both p < 0.001). The SNPs in MS and CBS were not related to relevant changes in homocysteine levels in CAD patients or controls. The different SNPs of MTHFR, MS, and CBS were not related to an increased event rate. CONCLUSION: Homocysteine level is a strong predictor of CV events. Subjects with and without CAD and SNPs in the enzyme MTHFR had increased homocysteine levels. This was not observed for MS and CBS SNPs. Although MTHFR SNPs alter homocysteine levels in patients and controls, these polymorphisms had no impact on prognosis in CAD patients.

RESUMO

BACKGROUND: Impaired renal function leads to dramatically increased risk for the development and progression of coronary artery disease (CAD). Therefore we aimed to assess the predictive value of different equations for estimated glomerular filtration rate (eGFR) in CAD-patients. METHODS: From the AtheroGene study 2135 patients were included. eGFR was calculated using the 4-variable Modification of Diet in Renal Disease (4MDRD) equation for serum creatinine (sCr), the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation for sCr and cystatin C (CysC) each alone, and in combination (CysC/sCr). eGFR was assessed regarding the combined outcome of cardiovascular death and non-fatal myocardial infarction and regarding complex CAD represented by a SYNTAX score ≥23. Median follow-up was 4.3years. RESULTS: Only the CKD-EPI equation using CysC could differentiate between eGFR >90ml/min/1.73m(2) vs. eGFR 60-90ml/min/1.73m(2) according to the occurrence of an endpoint event (log-rank test p=0.009). In the Cox regression analysis only eGFR calculated by CKD-EPI equation for CysC (Hazard ratio per 1 standard deviation (HR) 1.27 (95% CI 1.07-1.50); p=0.007) and for CysC/sCr (HR 1.22 (95% CI 1.02-1.46); p=0.026) were predictive regarding the outcome after adjustment for cardiovascular risk factors and Nt-proBNP. Furthermore, only eGFR calculated by CKD-EPI equation for CysC (odds ratio (OR) 1.57 (95% CI 1.36-1.78); p<0.001) and for CysC/sCr (OR 1.32 (95% CI 1.13-1.53); p<0.001) were significantly associated with a SYNTAX score ≥23. CONCLUSION: In patients with CAD the CKD-EPI equation for CysC and for CysC/sCr provided the best predictive value regarding the prognosis and the severity of CAD.

RESUMO

PURPOSE: The study examines the association between exposure to current and cumulative night shift work and subclinical parameters of atherosclerosis. METHODS: Participants of a population-based cohort study (the Gutenberg Health Study, N = 15,010) aged 35-64 years were examined at baseline (2007-2012). Investigations included measurements of arterial stiffness, vascular function [reactive hyperaemia (RH) index], and intima media thickness (IMT). Also, a complete job history (including up to 15 periods), occupational exposures, a variety of lifestyle, and dispositional variables were enquired. RESULTS: Night shift work was performed by 1071 out of 8065 currently employed individuals. The strongest association after adjustment for age, sex, job complexity level, being a manager, overtime work, and noise appeared for more than 660 night shifts within the last 10 years and a significantly increased arterial stiffness of 0.33 m/s. This reflects a 4 % flow velocity increase for individuals with more than 660 night shifts compared to non-night workers. Regarding the entire professional life, night shift workers showed a significantly decreased vascular function by -0.054 RH index points by using the same adjustment. IMT values did not differ statistically from non-night workers. Lifestyle and dispositional factors showed an influence on all used subclinical atherosclerosis parameters. CONCLUSIONS: The cross-sectional results demonstrate an association between night work and detrimental changes in the atherosclerotic process. The association is more pronounced with more years in night shift and is partly explained by lifestyle and dispositional factors. Longitudinal analyses are necessary to confirm the results.

RESUMO

INTRODUCTION: The advancements in cancer treatment and detection of early cancer have resulted in steady increase of adult cancer survivors over the years. However, due to the long term toxic effects of chemotherapy and radiotherapy, the incidence of cardiovascular diseases (CVD) is increasing in survivors. Identifying risk factors and interventions to reduce the excess burden of CVD in this vulnerable population is urgently needed. AIM: To investigate the cardiovascular risk factors (CVRFs), inflammation and coagulation profile in cancer survivors from a large population-based study. MATERIALS AND METHODS: Presence of CVRFs and laboratory markers have been compared in individuals with (n=1,359) and without (n=13,626) history of cancer. Standard laboratory profile, including blood glucose and lipid profile, has been evaluated in 15,010 individuals from the Gutenberg Health Study (GHS). Coagulation factors, D-dimer and von Willebrand factor (vWF) activity were available in N=4,993. RESULTS: The individuals with history of cancer were older compared to no history of cancer with mean age of 61,5years and 54.4years, respectively (p<0.001). Traditional CVRFs as diabetes (14% vs 8.8%), dyslipidemia (49.6% vs 43.7%) and hypertension (60.3 vs 48.7%) were more frequent whereas smoking was less frequent (14.5% vs 19.9%) in cancer survivors (p<0.001). The standard laboratory profile showed cancer survivors with lower erythrocyte, platelet and white blood cell counts and higher C-reactive protein (CRP), glucose, HbA1c and triglycerides levels (p<0.001). Multivariable logistic regression analysis adjusted for age, sex and CVRFs demonstrated an independent association with diabetes (odds ratio, OR: 1.24, 1.02-1.50; p=0.027) and higher CRP (OR: 1.01, 1.01-1.02; p=0.00071). Fibrinogen, FV, FVII, FVIII and FXI, D-dimer and vWF activity were higher in cancer survivors (p<0.001). Multivariable logistic regression confirmed an independent association with higher fibrinogen (OR: 1.002, 1.000-1.003) and vWF activity (OR: 1.005, 1.001-1.008). CONCLUSIONS: This is the first study investigating CVRFs, inflammation and coagulation profile in individuals with history of cancer from a well characterized population-representative adult sample. It gives evidence for higher prevalence of CVRFs, particularly diabetes in this vulnerable population. Markers of inflammation as CRP and fibrinogen and vWF activity were higher in cancer survivors independent of the cardiovascular risk profile. These results underline the increased risk of CVD and need for development of cardio-oncology programs offering cardiovascular prevention.

RESUMO

OBJECTIVE: Distressed ('Type D') personality is associated with adverse health outcomes in patients with cardiovascular disease (CVD). While personality traits from the Five-Factor Model are related to cognitive functioning, neither Type D personality nor its underlying traits negative affectivity (NA) and social inhibition (SI) have been investigated regarding cognition. We therefore compared the predictive value of Type D classification and its subcomponents NA and SI on planning performance in individuals with and without CVD. METHODS: Type D personality traits (DS14) were determined in a population-based sample of 4026 participants (including 549 with CVD) aged 40-80years from the Gutenberg Health Study (GHS) and related to planning performance as assessed with the Tower of London task. Current depression and anxiety were controlled as state variables. RESULTS: Type D personality status was negatively associated with planning performance in the CVD patient group only (p<0.001) but had no impact in the non-CVD group (p=0.40). In the overall sample, NA was negatively and SI positively associated with planning performance. No differential effect on planning between groups was found for depression and anxiety. CONCLUSION: While the subcomponents NA and SI in the population-based sample confirm and extend previous research on personality traits and cognition, Type D personality classification in combination with CVD emerged as a risk factor for decreased cognitive functioning, independent of depression and anxiety. These findings implicate the need to early focus on individual differences in cognitive functioning in patients with CVD.

RESUMO

For more than a decade the antiphospholipid syndrome (APS) has been reported to be caused mainly by antiphospholipid antibodies (aPL), which are not directed against phospholipids but against a complex of phospholipids and phospholipid binding proteins, so called cofactors (e.g. ß2-glycoprotein I [ß2GPI]). In fact, many researchers propose that the only relevant antigens in the APS are the cofactors themselves, with ß2GPI being the most important. Antibodies that bind to phospholipids in a cofactor-independent manner are considered insignificant for the pathogenesis of the APS. We review the evidence for this current pathophysiologic concept and argue that it has never been proven and is now clearly no longer tenable. First, there is undisputable evidence that cofactor-independent aPL are pathogenic and present in the blood of APS patients. Second, available epidemiologic and clinical studies do not support a dominant pathogenic role for anti-ß2GPI.
