AIM: Edoxaban, a nonvitamin K antagonist oral anticoagulant, is an oral factor Xa inhibitor approved for the prevention of stroke and systemic embolism in adult patients with atrial fibrillation and for the treatment and secondary prevention in adult patients with venous thromboembolism (VTE). This study details the design of the Edoxaban Treatment in routiNe clinical prActice for patients with Atrial Fibrillation in Europe (ETNA-AF-Europe) study - a postauthorization observational study, which is part of the postapproval plan for edoxaban agreed with the European Medicines Agency. METHODS: The ETNA-AF-Europe study (Clinicaltrials.gov: NCT02944019) is a multicenter, prospective, observational study that enrolled 13 980 patients with atrial fibrillation treated with edoxaban from 852 sites across 10 European countries (Austria, Belgium, Germany, Ireland, Italy, the Netherlands, Portugal, Spain, Switzerland, and the United Kingdom). Patients treated with edoxaban were prospectively enrolled and will be followed up for 4 years with yearly follow-up visits. ASSESSMENTS: The primary objective of the ETNA-AF-Europe study is to assess the real-world safety of edoxaban by evaluating bleeding events, including intracranial hemorrhage; drug-related adverse events, such as hepatic events; and cardiovascular and all-cause mortality. In addition, efficacy will be assessed by recording major adverse cardiovascular events including stroke, systemic embolic events, transient ischemic attacks, and also VTE episodes, acute coronary syndromes, and hospitalizations related to cardiovascular condition. Event rates will be compared with event rates reported in the PREvention oF thromboembolic events-European Registry in Atrial Fibrillation in atrial fibrillation (PREFER in AF) and PREFER in AF Prolongation registries, and in the Effective Anticoagulation with Factor Xa Next Generation in Atrial Fibrillation - Thrombolysis in Myocardial Infarction 48 study datasets.

Contemporary medicine is shifting towards person rather than disease-oriented care.1 With increasing life expectancy and the ageing of baby boomers, the proportion over 60 years is growing faster than the overall population, with worldwide estimates reaching 2 billion by 2050 (http://www.un.org/esa/population/publications/worldageing19502050).2 In parallel, acute coronary syndromes (ACS) and atrial fibrillation (AF)—the most frequent indications for dual platelet inhibition or anticoagulation—occur mostly in older patients.2–6 There is general agreement that people ≥75 years can be defined ‘elderly’; however, cutoffs as low as 65 years have been applied to important clinical datasets and risk scores.3,7–10 Moreover, ageing is a continuous process and life-span expansion is deflating (http://www.nber.org/papers/w18407). For these reasons, a threshold to define ‘elderly’ has been intentionally avoided in this document. Of note, over one third of patients admitted with acute myocardial infarction (MI) and two thirds dying from MI are over 75 years, but

- Abstract
Background and Aim: The management of patients with recent-onset atrial fibrillation (AF) presenting at emergency departments (EDs) varies widely. Our aim was to describe the management of patients with recent-onset (<48 hours) AF, to determine safety and efficacy of pharmacological cardioversion at the ED, and to evaluate the incidence of thromboembolism or death at 30 days., Methods: In a prospective, observational, single-center study, 236 subjects with recent-onset AF were consecutively enrolled from January 2011 until January 2013. Follow-up information was obtained by reviewing all available clinical records., Results: As first-line therapy, 45.3% (n = 107) received ibutilide, 28.8% (n = 68) vernakalant, 25% (n = 59) flecainide, and 0.8% (n = 2) amiodarone, respectively. Successful cardioversion was achieved in 72.5% (n = 171) of patients after first-line therapy. There was no significant difference between treatment groups. In univariable logistic regression analysis, age (odds ratio [OR] = 1.027; 95% confidence interval [CI], 1.003-1.052; P= .03), duration of symptoms (OR = 0.968; 95% CI, 0.938-0.999; P= .045), as well as the CHA2DS2-VASc score (1 point for Congestive heart failure, Hypertension, Age between 65 and 74 years, Diabetes, Vascular disease, Sex category if female and 2 points for previous TIA/Stroke and Age ≥ 75 years) (OR = 1.237; 95% CI, 1.01-1.515; P= .04) were associated with success of pharmacological cardioversion. Within 30 days, 1 patient suffered from fatal ischemic stroke., Conclusion: Pharmacological cardioversion followed by discharge after a short observation period is safe. There was no significant difference between the agents used in terms of short-term safety and efficacy. Importantly, the coherence of the ED to recent guidelines regarding first-line therapy is high., (Copyright © 2016 Elsevier Inc. All rights reserved.)

- Abstract
Among insured women, aged 19-26 years, those who discussed the HPV vaccine with their physician and received a recommendation were overwhelmingly more likely to be vaccinated. Student status and perception of the personal importance of vaccination were also predictive of vaccination. The strength of the physician's recommendation played a significant role in the decision to be vaccinated, resulting in a 4-fold greater likelihood of vaccination when women received a strong recommendation versus one that was not strong. Health care providers should be well-informed about HPV vaccination and recognize that the strength of their recommendation to patients will foster appropriate uptake., (Copyright © 2009 Elsevier Ltd.

- Abstract
Objectives: It is believed that adipose tissue acts as an endocrine organ by producing inflammatory mediators and thereby contributes to the increased cardiovascular risk seen in obesity. A link between adipose tissue mass and angiogenesis has been suggested. Vascular endothelial growth factor (VEGF) seems to be implicated in this process. Members of the glycoprotein (gp)130 ligand family regulate VEGF expression in other cells., Methods and Results: We used tissue explants as well as primary cultures of preadipocytes and adipocytes from human subcutaneous and visceral adipose tissue to investigate whether the gp130 ligands oncostatin M (OSM), interleukin-6 (IL-6), leukemia inhibitory factor (LIF), and cardiotrophin-1 (CT-1) regulate VEGF expression in human adipose tissue. Human subcutaneous and visceral adipose tissue responded to treatment with IL-6 and OSM with a significant increase in VEGF production. Human preadipocytes were isolated from subcutaneous and visceral adipose tissue. Adipocyte-differentiation was induced by hormone-supplementation. All cell types responded to IL-6 and OSM with a robust increase in VEGF protein production and a similar increase in VEGF-specific mRNA. Furthermore, IL-1beta synergistically enhanced the effect of OSM on VEGF production. AG-490, a JAK/STAT inhibitor, abolished the OSM-dependent VEGF induction almost completely. In mice, IL-6 and OSM increased serum levels of VEGF and VEGF mRNA and vessel density in adipose tissue., Conclusion: We speculate that the inflammatory cytokines IL-6 and OSM might support angiogenesis during adipose tissue growth by upregulating VEGF.

- Abstract
Background: Atherosclerosis is considered to be a chronic inflammatory disorder. Activation of the complement cascade is a major aspect of chronic inflammatory diseases. Complement components were identified in atherosclerotic plaques, and a correlation between adverse events and C5a plasma levels was found. These findings support the notion that complement activation contributes to development and progression of atherosclerotic lesions., Objectives: We investigated whether complement components C3a and C5a regulate plasminogen activator inhibitor (PAI-1) in human macrophages., Methods: Human monocyte-derived macrophages (MDM) and human plaque macrophages were cultured and incubated with the complement component C5a., Results: C5a increased PAI-1 up to 11-fold in human MDM and up to 2.7-fold in human plaque macrophages. These results were confirmed at the mRNA level using real time-polymerase chain reaction. Pertussis toxin or anti-C5aR/CD88 antibody completely abolished the effect of recombinant human C5a on PAI-1 production, suggesting a role of the C5a receptor. Experiments with antitumor necrosis factor (TNF)-alpha antibodies and tiron showed that the effect of C5a was not mediated by TNF-alpha or oxidative burst. Furthermore C5a induced NF-kappaB binding to the cis element in human macrophages and the C5a-induced increase in PAI-1 was completely abolished by an NF-kappaB inhibitor., Conclusions: We conclude that C5a upregulates PAI-1 in macrophages via NF-kappaB activation. We hypothesize that - if operative in vivo- this effect could favor thrombus development and thrombus stabilization in the lesion area. On the other hand one could speculate that C5a-induced upregulation of PAI-1 in plaque macrophages could act as a defense mechanism against plaque destabilization and rupture.

- Abstract
There is ample evidence supporting the view that alterations in the balance between matrix deposition and matrix degradation brought about by changes in the respective activities of matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) contribute significantly to cardiac dysfunction and disease. Here we show that TIMP-1 was upregulated up to threefold after treatment with the inflammatory mediator and gp130 ligand oncostatin M (OSM) in human adult cardiac myocytes and fibroblasts. The Erk1/2 inhibitor PD98059 and the p38 inhibitor SD202190 abolished the effect of OSM on TIMP-1 production in both cell types. Human cardiac myocytes and human cardiac fibroblasts also express MMP-1, 2, 3 and 9, and TIMP-2 constitutively. OSM, however, did not affect the expression of these proteins. In addition also the other gp130 ligands tested, cardiotrophin-1 (CT-1), interleukin-6 (IL-6) and leukemia inhibitory factor (LIF) had no effect on the expression of TIMPs and MMPs studied. We speculate that OSM by inducing TIMP-1 expression counteracts excessive proteolysis and unrestricted matrix degradation during inflammatory processes in the heart. The notion that OSM favors matrix stabilization in the human heart is further supported by our earlier observation that OSM also upregulates PAI-1, the physiological inhibitor of the protease urokinase-type PA (u-PA), which in turn is essential for extracellular proteolysis. Therefore we propose a role for the gp130 ligand OSM in the modulation of cardiac remodeling and repair processes.

- Abstract
Background: Adipose tissue is a prominent source of plasminogen activator inhibitor-1 (PAI-1), the primary physiological inhibitor of plasminogen activation. Increased PAI-1 expression acts as a cardiovascular risk factor, and plasma levels of PAI-1 strongly correlate with body mass index (BMI). Elevated serum levels of interleukin-6 (IL-6), an inflammatory cytokine and a member of the glycoprotein 130 (gp130) ligand family, are found in obese patients and might indicate low-grade systemic inflammation. Another gp130 ligand, oncostatin M (OSM), upregulates PAI-1 in cardiac myocytes, astrocytes, and endothelial cells. We used tissue explants and primary cultures of preadipocytes and adipocytes from human subcutaneous and visceral adipose tissue to investigate whether IL-6 and OSM affect PAI-1 expression in fat., Methods and Results: Human subcutaneous and visceral adipose tissue responded to treatment with IL-6 and OSM with a significant increase in PAI-1 production. Human preadipocytes were isolated from subcutaneous and visceral adipose tissue. Adipocyte differentiation was induced by hormone supplementation. All cell types expressed receptors for IL-6 and OSM and produced up to 12-fold increased levels of PAI-1 protein and up to 9-fold increased levels of PAI-1 mRNA on stimulation with IL-6 and OSM. AG-490, a janus kinase/signal transducer and activator of transcription inhibitor, abolished the OSM-dependent PAI-1 induction almost completely., Conclusions: We have for the first time established a link between the gp130 ligands, the proinflammatory mediators IL-6 and OSM, and the expression of PAI-1 in human adipose tissue. Thus, we speculate that IL-6 and OSM, by upregulating PAI-1 in adipose tissue, can contribute to the increased cardiovascular risk of obese patients.

- Abstract
Between 1992 and 1994, the Department of Veterans Affairs (VA) experimented with mobile clinics to provide health care for rural veterans. The objective was to assess the health status of rural mobile clinics' patients and compare this with patients receiving care in VA hospital-based clinics. This study hypothesized that hospital-based clinic patients would be more ill (i.e., have a greater reduction in health status). The Medical Outcomes Study (MOS) Short Form was used to evaluate patients' health status. Most patients sought care for the management of chronic disease. Patients in both groups had similar types of diseases. Mobile clinic patients were as ill as hospital-based patients (i.e., similar health status scores). This study shows that rural veterans have a case mix and a reduction in health status similar to that of VA hospital-based patients. Planners should account for this health reduction when planning the kinds of facilities and services needed in rural areas.

- Abstract
In 1988 the Veterans' Benefits and Services Act attempted to solve the problem of the lack of adequate VA healthcare facilities in rural areas by establishing a demonstration program using mobile clinics. Six clinics operated in areas that were at least 100 miles from a VA healthcare facility during the time period between October 1, 1992 and May 28, 1994. This article evaluated the effect of the mobile clinics' structural limitations on clinical care, the increased number of sites on VA usage, and cost. Limited space for storage of medical records and the unavailability of laboratory, electrocardiographic, or radiographic facilities significantly affected clinical practice. However, even with these space limitations, veterans' use of healthcare in the areas served by the mobile clinics increased significantly in comparison to reference areas. The direct costs per visit averaged more than three times what the VA would have reimbursed the private sector.

- Abstract
Objective: The relationship between hospital utilization and psychometric, demographic, and diagnostic data was examined among veterans with psychiatric problems., Methods: Data were obtained from the records of 500 psychiatric inpatients admitted to a Veterans Affairs medical center between 1984 and 1987 and followed for four years. All patients completed the Minnesota Multiphasic Personality Inventory, the California Personality Inventory, the Millon Clinical Multiaxial Inventory, and the Psychological Inventory of Personality and Symptoms. Stepwise linear regression analysis was used to predict the number and length of inpatient stays, and Cox and logistic regression analyses predicted rehospitalization., Results: Higher rates of psychiatric hospital utilization were found among patients who were unmarried, who had disabilities connected with their military service, who had lower levels of adaptive functioning, and who were diagnosed as having posttraumatic stress disorder, drug or alcohol use disorder, or passive-aggressive or antisocial personality disorder. Higher utilization was also found among those whom psychometric data characterized as less responsible and more compulsive. The data also predicted the length of subsequent medical hospitalization and identified patients who stayed out of the hospital longer and who were not rehospitalized., Conclusions: Hospital utilization was found to be a function of psychiatric diagnosis, marital status, and various personality factors. Factors relating to social disadvantage also played a role. Axis I diagnoses, particularly substance use disorders, were as important as, if not more important than, axis II diagnoses in predicting utilization.

- Abstract
Since the early 1980s, health care for women veterans in the Department of Veterans Affairs (VA) has improved considerably, although problems still remain. The lack of privacy for women at many VA facilities and the provision of incomplete physical examinations for women continue to be problematic issues. A 1992 congressional appropriation of $7.5 million has substantially increased the awareness of women veterans health care in the VA. This appropriation, from Public Law 102-585, Veterans Health Care Act of 1992, Title I-Women Veterans Health Programs, has allowed VA to expand services for women veterans. Using these funds, VA has established eight comprehensive women veterans health centers, 23 full-time women veterans coordinators, and four regional stress disorder teams. This paper describes these and other important new initiatives and discusses how they will serve as the foundation on which VA expands care for women within the context of a changing health care system.

- Abstract
Women veterans represent a rapidly growing segment of the veteran population. This study examines how the utilization of VA hospitals by women veterans has changed since 1980. Information on the use of VA hospitals was obtained from the discharge database for all VA hospitals. The demographics of the veteran population was compiled from the Veteran Population Files, which contain annual estimates of the number of veterans by age and sex. The VA hospital discharge rate for women increased nearly 29 percent during the 1980's while the VA user rate increased nearly 18.6 percent for women. The increase in the average number of VA stays per user was smaller for women than for men (8.4 percent versus 11 percent). Substantial increases in the utilization of VA hospitals by women veterans occurred during the 1980's. In most cases these increases were larger for women veterans than for men veterans. However, women veterans still use VA hospitals at about one-half the rate for men. Regardless, the VA system will continue to be an important source of health care for women.

- Abstract
Time series analysis is one of the methods health services researchers, managers and planners have to examine and predict utilization over time. The focus of this study is univariate time series techniques, which model the change in a dependent variable over time, using time as the only independent variable. These techniques can be used with administrative healthcare databases, which typically contain reliable, time-specific utilization variables, but may lack adequate numbers of variables needed for behavioral or economic modeling. The inpatient discharge database of the Department of Veterans Affairs, the Patient Treatment File, was used to calculate monthly time series over a six-year period for the nation and across US Census Bureau regions for three hospital utilization indicators: average length of stay, discharge rate, and multiple stay ratio, a measure of readmissions. The first purpose of this study was to determine the accuracy of forecasting these indicators 24 months into the future using five univariate time series techniques. In almost all cases, techniques were able to forecast the magnitude and direction of future utilization within a 10% mean monthly error. The second purpose of the study was to describe time series of the three hospital utilization indicators. This approach raised several questions concerning Department of Veterans Affairs hospital utilization.

- Abstract
Individual energy expenditure (kcal/kg/day) was calculated from a detailed set of questions from the Health Promotion and Disease Prevention Supplement of the 1985 National Health Interview Survey. Responses to three single-item, self-assessment questions were compared to the energy expenditure variable to test criterion validity. Spearman's correlation coefficient revealed moderate correlations between energy expenditure and corresponding levels of self-assessed leisure-time physical activity for each single-item question (r = 0.14 to 0.41). For purposes of measuring prevalence of physical activity, the energy expenditure variable was used to categorize individuals into activity levels. The single-item questions were found to have Spearman's correlations with the categorical measures ranging from 0.11 to 0.37 for leisure-time activities. Generally higher correlations were found for males and younger age groups (18-34 years). The relationships were interpreted as being weak relative to an expected correlation of 0.75 for criterion validation. However, the single-item questions show promise for obtaining proxy estimates of the degree of leisure-time physical activity in a population.
