Discussion is more convincing than standard, unidirectional messaging, but its interactive nature makes it difficult to scale up. We created a chatbot to emulate the most important traits of discussion. A simple argument pointing out the existence of a scientific consensus on the safety of genetically modified organisms (GMOs) already led to more positive attitudes towards GMOs, compared with a control message. Providing participants with good arguments rebutting the most common counterarguments against GMOs led to much more positive attitudes towards GMOs, whether the participants could immediately see all the arguments or could select the most relevant arguments in a chatbot. Participants holding the most negative attitudes displayed more attitude change in favour of GMOs. Participants updated their beliefs when presented with good arguments, but we found no evidence that an interactive chatbot proves more persuasive than a list of arguments and counterarguments., (© 2022.

People tend to evaluate information from reliable sources more favourably, but it is unclear exactly how perceivers' worldviews interact with this source credibility effect. In a large and diverse cross-cultural sample (N = 10,195 from 24 countries), we presented participants with obscure, meaningless statements attributed to either a spiritual guru or a scientist. We found a robust global source credibility effect for scientific authorities, which we dub 'the Einstein effect': across all 24 countries and all levels of religiosity, scientists held greater authority than spiritual gurus. In addition, individual religiosity predicted a weaker relative preference for the statement from the scientist compared with the spiritual guru, and was more strongly associated with credibility judgements for the guru than the scientist. Independent data on explicit trust ratings across 143 countries mirrored our experimental findings. These findings suggest that irrespective of one's religious worldview, across cultures science is a powerful and universal heuristic that signals the reliability of information., (© 2022.

Autosomal dominant polycystic kidney disease (ADPKD) is the most prevalent hereditary kidney disease. Recent evidence suggests that the pathogenesis of ADPKD is a complex web of abnormal cellular processes including altered cell signaling, disordered cell metabolism, impaired autophagy, increased apoptosis, mitochondrial dysfunction and chronic inflammation. Sodium-glucose cotransporter (SGLT) inhibitors (SGLTi) reduce body weight, blood pressure and blood glucose levels, have kidney and cardiovascular protective activity, and have been reported to decrease inflammation, increase autophagy and improve mitochondrial dysfunction. We now review results from preclinical studies on SGLTi for ADPKD identified through a systematic search of the MEDLINE, Cochrane Library, Embase and PubMed databases. Potential underlying mechanisms for the conflicting results reported as well as implications for clinical translation are discussed, as ADPKD patients were excluded from clinical trials exploring kidney protection by SGLT2 inhibitors (SGLT2i). However, they were not excluded from cardiovascular safety trials or trials for cardiovascular conditions. A post-hoc analysis of the kidney function trajectories and safety of SGLT2i in ADPKD patients enrolled in such trials may provide additional information. In conclusion, SGLT2i are cardio- and nephroprotective in diverse clinical situations. Currently, it is unclear whether ADPKD patients may benefit from SGLT2i in terms of kidney function preservation, and their safety in this population remains unexplored. We propose a roadmap to address this unmet clinical need., (© The Author(s) 2022. Published by Oxford University Press on behalf of the ERA.)

Background and Objectives: Excessive coronary thrombus burden is known to cause an increase in mortality and major adverse cardiac events (MACEs) in NSTE-ACS (non-ST acute coronary syndrome) patients. We investigated the association between the systemic immune-inflammation index (SII) and coronary thrombus burden in patients with non-ST segment elevation myocardial infarction (NSTEMI) who underwent coronary angiography and percutaneous coronary intervention (PCI). Materials and Methods: A total of 389 patients with the diagnosis of NSTEMI participated in our study. Coronary thrombus burden was classified in the TIMI (thrombolysis in myocardial infarction) thrombus grade scale and patients were divided into two groups: a TIMI thrombus grade 0-1 group ( n = 209, 157 males) and a TIMI thrombus grade 2-6 group ( n = 180, 118 males). Demographics, angiographic lesion images, coronary thrombus burden, clinical risk factors, laboratory parameters, and SII score were compared between the two groups. Results: The high thrombus burden patient group had a higher neutrophil count, WBC count, platelet count, and systemic immune-inflammation index (SII) ( p < 0.001). The receiver operating characteristic (ROC) curve analysis showed that at a cutoff of 1103, the value of SII manifested 74.4% sensitivity and 74.6% specificity for detecting a high coronary thrombus burden. Conclusions: Our study showed that the SII levels at hospital admission were independently associated with high coronary thrombus with NSTEMI.

Background: Despite a high demand for people to participate in disaster volunteering, the extent of contribution received from female volunteers in disaster response organisations constitutes an important debate. In the Elazığ earthquake on 24 January 2020, the role of female volunteers in rescuing a female victim from the wreckage once again demonstrated the importance of considering female volunteers when creating response capacities for disaster risks., Objective: This qualitative study aims to evaluate the roles of female volunteers who play an active role in disaster response organisations in a society with gender equality issues., Methods: This qualitative study included 15 National Medical Rescue Team (UMKE) female volunteers who took an active role in the Elazig earthquake and was performed between 15.07.2020 and 16.04.2021. Data were collected using an in-depth interview method. The data were analyzed using content analysis and the comments were given descriptively., Results: Based on the qualitative analysis, the following concepts were explored among the participants: Volunteering, volunteering in disasters, the effects of volunteering on social life, being a woman in disasters, volunteering female in disasters, the 'motherhood myth', gender inequality. Women are key actors in tackling disaster damage and increasing available social resilience to disasters. In addition, women can use special attributes such as motherhood, which is socio-culturally defined and taught as an advantage, for the common good of society. Moreover, special elements, such as the image of the 'superwoman' in relation to the responsibilities imposed on women in disaster response organisations, which distort gender equality against women, appear as possible factors of harm for women., Conclusion: This study shows that female volunteers can play a life-saving role in chaotic situations such as disasters, contribute to the empowerment of women, increase sensitivity to gender and, in connection with this, the development of democracy in societies where gender inequality is high. On the other hand, special situations such as the image of 'superwoman', which aims for excellence in both private and public spheres in the responsibilities imposed on women, can destroy gender equality against women and increase women's fragility.

Objective: Aberrant internal carotid arteries (ICAs) may take abnormal courses in the cervical region. We present the ICA imaging features that suggest the presence of a submucosal mass in the posterior pharyngeal wall caused by such an aberration., Methods: Cervical computed tomography angiography images of 2400 patients obtained over 5 years were retrospectively reviewed. The ICA courses at the levels of the hypopharynx and oropharynx were evaluated. Aberrant ICAs running posterior to the pharynx were selected. Vessel location was classified into 3 types: lateral to the vertebral foramen (normal, type I); between the lateral foramen and the uncovertebral joint (type II); and medial to the uncovertebral joint (type III). Medical records were examined, and relationships between symptoms, the ICA variations, and imaging features evaluated., Results: Cervically aberrant ICAs of type II were detected in 45 patients and aberrations of type III in 18. In the latter group, the mean patient age was 66 years, 12 were men and 6 were women. Six (33%) patients (4 men) had clinical symptoms associated with their aberrant ICA courses. In 2 men (11%), both ICAs took aberrant courses. Otherwise, the right ICA was affected in 9 (50%) cases and the left ICA in 7 (39%)., Discussion: Parapharyngeal ICA aberrations were both common and asymptomatic. Such ICAs may be damaged during pharyngeal surgery or intubation. The ICA location should be investigated before any interventional procedure., Competing Interests: This article is not under consideration elsewhere.

Background and objectives: Mortality may increase in hypouricemia as well as inhyperuricemia. We assessed the predictive value of low serum uric acid (SUA) levels on the risk of overall mortality or a composite endpoint of death and nonfatal events. Materials and Methods: In 1013 community-based middle-aged adults, free of uncontrolled diabetes and coronary heart disease at baseline, the association of sex-specific SUA tertiles with defined outcomes was evaluated prospectively by logistic regression, stratified to gender and presence of type-2 diabetes, using recent criteria. Results : Totally, 43 deaths and additional incident nonfatal events in 157 cases were recorded at a median 3.4 years' follow-up. Multivariable linear regression disclosed SUA to be significantly associated among non-diabetic individuals positively with creatinine, triglycerides, and body mass index in women further with fasted glucose. In multivariable-adjusted logistic regression analysis, sex-specifically dichotomized baseline uric acid (<5.1 and <4.1 mg/dL vs. higher values) significantly predicted the non-fatal events in the whole sample (relative risk (RR) 1.51 [95% confidence interval (CI) 1.02; 2.26]), as well as in men, while composite endpoint in the whole sample tended to rise (RR 1.38). Compared with the intermediate one, the top and bottom SUA tertiles combined tended to confer mortality risk (RR 2.40 [95% CI 0.89; 6.51]). Adverse outcomes in diabetic women were predicted by tertiles 2 and 3. Conclusions : Inverse association of SUA with adverse outcomes, especially in men, is consistent with the involvement of uric acid mass in autoimmune activation. The positive association of uric acid with adverse outcomes in diabetic women is likely mediated by concomitant high-density lipoprotein dysfunction.

Objective: This study aimed to evaluate the safety of direct oral anticoagulants (DOACs) in patients with non-valvular atrial fibrillation (NVAF) during daily clinical practice., Methods: This was a prospective study conducted between January 01, 2016, and April 01, 2017, in patients aged ≥18 years with a diagnosis of NVAF. We performed the study in 9 clinical centers from different regions of Turkey, and the mean follow-up period was 12+2 months. We investigated major and minor bleeding events of DOAC., Results: A total of 1807 patients with NVAF were enrolled. The mean age of the patients was 73.6±10.2 years, CHA2DS2-VASc score was 3.6±1.4, and HAS-BLED score was 2±1.2. The most frequently prescribed DOAC was dabigatran 110 mg bid in 409 (22.6%) patients. The patients on apixaban 2.5 mg bid were older (p<0.001). Patients on rivaroxaban 15 mg od also had a higher prevalence of chronic renal failure, 46 (16.7%) patients. A total of 205 (11.4%) bleeding events were observed; among these, 34 (1.9%) patients had major bleeding and 171 (9.4%) patients had minor bleeding. The major and minor bleeding events were 2/273 (0.7%) and 30/273 (10.9%) in patients receiving dabigatran 150 mg bid, 13/409 (3%) and 44/409 (10.7%) in patients receiving dabigatran 110 mg bid, 4/385 (1%) and 42/385 (10.9%) in patients receiving rivaroxaban 20 mg od, 8/276 (2.9%) and 27/276 (9.7%) in patients receiving rivaroxaban 15 mg od, 3/308 (0.9%) and 14/308 (4.5%) in patients receiving apixaban 5 mg bid, 4/156 (2.5%) and 14/156 (9%) in patients receiving apixaban 2.5 mg bid, respectively. The total bleeding events were 17 (5.6%) in patients receiving apixaban 5 mg, less than those receiving other DOACs. On multivariate analyses, rivaroxaban 20 mg od (p=0.002), ATRIA and HAS-BLED scores, and peripheral artery disease were independent indicators of bleeding. The most frequent location of major bleeding was the gastrointestinal system (GIS) [17 (0.9%) patients], and the most frequent location of minor bleeding was the gingiva [45 (2.5%) patients]., Conclusion: This study showed that similar results as the previous real-life study; however, we had some different results, such as the GIS tract bleeding was more frequent in patients receiving dabigatran 110 mg bid. The major and intracranial bleeding events were similar for different DOACs; and among DOACs, only rivaroxaban 20 mg od was associated with a high risk of bleeding.

Objective: Apelin is a novel adipocytokine with a significant role in ischemia/reperfusion injury that is synthesized and secreted in myocardial cells and coronary endothelium. There is debate on its value for the diagnosis and prognosis of myocardial infarction. We aimed to investigate plasma apelin level in patients with acute ST segment elevation (STEMI) and non-ST segment elevation (NSTEMI) myocardial infarction and its relationship with left ventricular function and prognostic parameters., Methods: Forty-one patients with STEMI, 21 patients with NSTEMI and 10 patients as control group with normal coronary angiograms were included. Plasma apelin level at presentation was investigated regarding its relationship with other diagnostic and prognostic parameters., Results: Apelin level was significantly higher in acute myocardial infarction (0.31 ± 0.56 ng/mL) compared to control group (0.08 ± 0.05 ng/mL) (p < 0.01). Likewise, it was found to be significantly higher in STEMI group (0.45 ± 0.73 ng/mL) compared to control group (0.08 ± 0.05 ng/mL) (p < 0.01). Although apelin was higher in NSTEMI group (0.13 ± 0.10 ng/mL) compared to control group (0.08 ± 0.05 ng/mL), this difference was not statistically significant (p > 0.05). No correlation was found between apelin and NT-proBNP, hsCRP, troponin, ejection fraction (EF) and Killip score (p > 0.05). A positive correlation was found between apelin and TIMI, GRACE and Gensini scores (p < 0.05). Only GRACE score was found to be correlated with apelin in MI groups., Conclusion: Apelin level was found to be high in acute myocardial infarction. With its inotropic and vasodilator effects, apelin was thought to have a protective role against severe ischemia., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2021.)

Congenital absence of the pericardium is not a common condition in daily practice. There are no obvious and clear symptoms. This condition, which is diagnosed incidentally, may cause some complications when not diagnosed. Therefore, imaging techniques, such as echocardiography, are essential. In this article, we present a rare case of pericardial agenesis., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors., (Copyright: © 2021 by Istanbul Northern Anatolian Association of Public Hospitals.)

Aims  This study evaluated the clinical prospects of Coronary Artery Disease-Reporting and Data System (CAD-RADS) scoring in coronary computed tomography angiography (CTA). The aim of the study was to determine the guidance value of CAD-RADS scoring in patient follow-up after CTA. Methods and Materials  Reports of cases reported between 2010 and 2013 were reevaluated with CAD-RADS scoring. Clinical risk analysis was performed with initial forms of anamnesis. Clinical follow-up was performed on 7 to 10 years (mean: 8 years, 4 months) hospital records. Univariate and multivariate Cox modeling was performed with Kaplan-Meier method to define the relationship between clinical (age, gender, diabetes mellitus, hypertension, smoking, family history) and CAD-RADS variables, and for risk analysis based on these causes. Cox proportional-hazards analysis results were presented as a hazard ratio with a 95% confidence interval. CAD-RADS scores were evaluated as meaningful determinants of univariate and multivariate Cox proportional survival analysis. Results  Totally, 359 cases were evaluated in the study. Severe coronary pathology development rate was observed as CAD-RADS 0to 1%, CAD-RADS 1 to 3%, CAD-RADS 2 to 4%, CAD-RADS 3 to 9%, CAD-RADS 4A to 21%, 4B to 25%, CAD-RADS 5 to 50%. There were no coronary artery deaths in CAD-RADS 1,2,3 cases in 10 years of follow-up. Two cases with CAD-RADS 4 A score, three cases with 4 B score, and four patients with CAD-RADS 5 had a history of death as a result of coronary disease. Conclusions  The cases with a high risk of side effects with CAD-RADS scores were clearly shown. CAD-RADS score accurately identifies risks in postimaging follow-up and is a reliable reporting system in the required treatment planning., Competing Interests: Financial Support and SponsorshipConflict of InterestNote Nil.

Efficiently communicating information on vaccination is crucial to maintaining a high level of immunization coverage, but it implies finding the right content for the right audience. Provaccination individuals, who represent the majority of the population, and who have been neglected in the literature, could play an important role relaying provaccination messages through informal discussions, if only these messages are (a) found plausible, (b) remembered, and (c) shared. We conducted 7 experiments on 2,761 provaccination online participants (United States and United Kingdom), testing whether the valence of a statement (positive or negative) and its rhetorical orientation (pro- or antivaccine) affected these 3 steps. Participants deemed more plausible, were more willing to transmit (and actually transmitted more), but did not remember positively framed statements better. Provaccination rhetorical orientation had little or no effect. Overall, the framing effects observed were dramatic: one framing made participants very eager to transmit a statement, while another made them reluctant to transmit it at all. The framing effects also influenced vaccination attitudes, with participants exposed to positively framed statements reporting more positive attitudes toward vaccination. Since messages have to be framed one way or the other, the framing effects demonstrated here should be considered when designing public health messages.

People often attribute rumours to an individual in a knowledgeable position two steps removed from them ( a credible friend of a friend ), such as 'my friend's father, who's a cop, told me about a serial killer in town'. Little is known about the influence of such attributions on rumour propagation, or how they are maintained when the rumour is transmitted. In four studies ( N = 1824) participants exposed to a rumour and asked to transmit it overwhelmingly attributed it either to a credible friend of a friend, or to a generic friend (e.g. 'a friend told me about a serial killer in town'). In both cases, participants engaged in source shortening : e.g. when told by a friend that 'a friend told me …' they shared the rumour as coming from 'a friend' instead of 'a friend of friend'. Source shortening and reliance on credible sources boosted rumour propagation by increasing the rumours' perceived plausibility and participants' willingness to share them. Models show that, in linear transmission chains, the generic friend attribution dominates, but that allowing each individual to be exposed to the rumour from several sources enables the maintenance of the credible friend of a friend attribution., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article., (© The Author(s) 2020.)

Background and Purpose: Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes., Methods: This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups., Results: A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05)., Conclusion: Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.

We agree with Cushman that rationalizations are the product of biological adaptations, but we disagree about their function. The data available do not show that rationalizations allow us to reason better and make better decisions. The data suggest instead that rationalizations serve reputation management goals, and that they affect our behaviors because we are held accountable by our peers.

Mis information and misunderstanding of science can partially explained by cognitive processes rooted in our evolutionary past. Science communication can use this knowledge to overcome these cognitive limits., (© 2020 The Authors.)

Selecting good sources of information is a critical skill to navigate our highly social world. To evaluate the epistemic reputation of potential sources, the main criterion should be the relevance of the information they provide us. In two online experiments ( N = 801), we found that receivers are more thankful toward, deem more competent, and are more likely to request information in the future from sources of more relevant messages-if they know the message to be accurate or deem it plausible. To prevent sources from presenting information as more relevant than it is in order to improve their reputation, receivers lower the reputation of sources sending messages that are more relevant-if-true, if they know the message to be inaccurate. Our research sheds light on the reputational trade-offs involved in choosing what information to communicate and helps explain transmission patterns such as rumors diffusion.

Background and objectives: Despite being within the normal reference range, changes in thyroid stimulating hormone (TSH) levels have negative effects on the cardiovascular system. The majority of patients admitted to hospital with acute coronary syndrome (ACS) are euthyroid. The aim of this study was to investigate the effect of TSH level on the prognosis of in-hospital and follow-up periods of euthyroid ACS patients. Materials and Methods: A total of 629 patients with acute coronary syndrome without thyroid dysfunction were included in the study. TSH levels of patients were 0.3-5.33 uIU/mL. Patients were divided into three TSH tertiles: TSH level between (1) 0.3 uIU/mL and <0.90 uIU/mL ( n = 209), (2) 0.90 uIU/mL and <1.60 uIU/mL ( n = 210), and (3) 1.60 uIU/mL and 5.33 uIU/mL ( n = 210). Demographic, clinical laboratory, and angiographic characteristics were compared between groups in terms of in-hospital and follow-up prognosis. Results: Mean age was 63.42 ± 12.5, and 73.9% were male. There was significant difference between tertiles in terms of TSH level at admission ( p < 0.001), the severity of coronary artery disease ( p = 0.024), in-hospital mortality ( p < 0.001), in-hospital major hemorrhage ( p = 0.005), total adverse clinical event ( p = 0.03), follow-up mortality ( p = 0.022), and total mortality ( p < 0.001). In multivariate logistic regression analysis, the high-normal TSH tertile was found to be cumulative mortality increasing factor (OR = 6.307, 95%; CI: 1.769-22.480; p = 0.005) during the 6-month follow-up period after hospitalization and discharge. Conclusions: High-normal TSH tertile during hospital admission in euthyroid ACS patients is an independent predictor of total mortality during the 6-month follow-up period after hospitalization and discharge.

Background: The Glasgow prognostic score (GPS), which is obtained from a combination of C-reactive protein (CRP) and serum albumin level, predicts poor prognoses in many cancer types. Systemic inflammation also plays an important role in pathogenesis of cardiovascular diseases. In this study, we aimed to investigate the effect of inflammation-based GPS on in-hospital and long-term outcomes in patients hospitalized in intensive cardiovascular care unit (ICCU). Methods: A total of 1004 consecutive patients admitted to ICCU were included in the study, and patients were divided into three groups based on albumin and CRP values as GPS 0, 1, and 2. Patients' demographic, clinic, and laboratory findings were recorded. In-hospital and one-year mortality rates were compared between groups. Results: Mortality occurred in 109 (10.8%) patients in in-hospital period, 82 (8.1%) patients during follow-up period, and thus, cumulative mortality occurred in 191 (19.0%) patients. Patients with a high GPS score had a higher rate of comorbidities and represented increased inflammatory evidence. In the multivariate regression model there was independent association with in-hospital mortality in GPS 1 patients compared to GPS 0 patients (Odds ratio, (OR); 5.52, 95% CI: 1.2⁻16.91, p = 0.025) and in GPS 2 patients compared to GPS 0 patients (OR; 7.01, 95% CI: 1.39⁻35.15, p = 0.018). A higher GPS score was also associated with a prolonged ICCU and hospital stay, and increased re-hospitalization in the follow-up period. Conclusion: Inflammation based GPS is a practical tool in the prediction of worse prognosis both in in-hospital and one-year follow-up periods in ICCU patients., Competing Interests: The authors declare that they have no conflict of interest.

Background and Objectives: Cranial magnetic resonance imaging findings of patients considered to be cryptogenic stroke may be useful in determining the clinical and prognostic significance of arrhythmias, such as atrial premature beats and atrial run attacks, that are frequently encountered in rhythm Holter analysis. This study was conducted to investigate the relationship between short atrial runs and frequent premature atrial contractions detected in Holter monitors and infarct distributions in cranial magnetic resonance imaging of patients diagnosed with cryptogenic stroke., Materials and Methods: We enrolled the patients with acute ischemic stroke whose etiology were undetermined. We divided the patients in two groups according to diffusion-weighted magnetic resonance imaging as single or multiple vascular territory acute infarcts. The demographic, clinical, laboratory, echocardiographic, and rhythm Holter analyses were compared., Results: The study investigated 106 patients diagnosed with cryptogenic stroke. Acute cerebral infarctions were detected in 31% of the investigated patients in multiple territories and in 69% in a single territory. In multivariate logistic regression analysis, the total premature atrial contraction count (OR = 1.002, 95% CI: 1.001⁻1.004, p = 0.001) and short atrial run count (OR = 1.086, 95% CI: 1.021⁻1.155, p = 0.008) were found as independent variables that could distinguish between infarctions in a single or in multiple vascular territories., Conclusions: Rhythm Holter monitoring of patients with infarcts detected in multiple vascular territories showed significantly higher premature atrial contractions and short atrial run attacks. More effort should be devoted to the identification of cardioembolic etiology in cryptogenic stroke patients with concurrent acute infarcts in the multiple vascular territories of the brain., Competing Interests: The authors declare that they have no conflict of interest.

Background: The use of warfarin and aspirin in combination is restricted to limited patients under relevant guidelines., Aims: To evaluate the prevalence of the inappropriate combination of aspirin and warfarin therapy in daily practice and its risks., Study Design: Cross-sectional study., Methods: The awareness, efficacy, safety, and time in the therapeutic range of warfarin in the Turkish population study is a multi-center observational study that includes 4987 patients using warfarin for any reason between January 1, 2014, and December 31, 2014. To determine the prevalence of inappropriate combination use in daily practice, all patients who had a history of atherosclerotic disease (ischemic heart disease, peripheral artery disease) or cerebrovascular disease (n=1498) were excluded. The data of 3489 patients were analyzed. We defined inappropriate combination as all patients who received aspirin and warfarin regardless of the indication for warfarin use, under the direction of the European Society of Cardiology guideline recommendation., Results: The mean age of patients was 59.2±13.8 years (41.8% male). The prevalence of the inappropriate use of warfarin and aspirin combination was 20.0%. The prevalence of combination therapy in patients with a primary indication for mechanical heart valve, non-valvular atrial fibrillation, and other reasons was 20.5%, 18.7%, and 21.0%, respectively. Multivariate logistic regression analysis revealed that age (odds ratio, 1.009; 95% confidence interval, 1.002-1.015; p=0.010), heart failure (odds ratio, 1.765; 95% confidence interval, 1.448-2.151; p<0.001), smoking (odds ratio, 1.762; 95% confidence interval, 1.441-1.153; p<0.010), chronic kidney disease (odds ratio, 2.057; 95% confidence interval, 1.494-2.833; p<0.001), and deep vein thrombosis (odds ratio, 0.463; 95% confidence interval, 0.229-0.718; p=0.001) were independent predictors of combination therapy (r2=0.66). The mean time in therapeutic range of patients receiving combination therapy was significantly lower than in those on warfarin monotherapy (51.6±27.05 vs. 54.7±23.93; p=0.006). Overall, 19.4% (n=677) of patients had a bleeding event (major bleeding 13.0%, n=88) within a year. Percentages of patients with combination therapy were significantly higher in patients with major bleeding than in patients without major bleeding (29.5% vs. 19.7%; p=0.023)., Conclusion: Our study demonstrated that 20.0% of patients taking warfarin use concomitant aspirin inappropriately in daily practice. Patients receiving aspirin with warfarin were demonstrated to have more comorbidities, lower time in therapeutic range levels, and higher bleeding rates.

Objective: It has been reported that women receive fewer preventive recommendations regarding pharmacological treatment, lifestyle modifications, and cardiac rehabilitation compared with men who have a similar risk profile. This study was an investigation of the impact of gender on cardiovascular risk profile and secondary prevention measures for coronary artery disease (CAD) in the Turkish population., Methods: Statistical analyses were based on the European Action on Secondary and Primary Prevention through Intervention to Reduce Events (EUROASPIRE)-IV cross-sectional survey data obtained from 17 centers in Turkey. Male and female patients, aged 18 to 80 years, who were hospitalized for a first or recurrent coronary event (coronary artery bypass graft, percutaneous coronary intervention, acute myocardial infarction, or acute myocardial ischemia) were eligible., Results: A total of 88 (19.7%) females and 358 males (80.3%) were included. At the time of the index event, the females were significantly older (p=0.003) and had received less formal education (p<0.001). Non-smoking status (p<0.001) and higher levels of depression and anxiety (both p<0.001) were more common in the female patients. At the time of the interview, conducted between 6 and 36 months after the index event, central obesity (p<0.001) and obesity (p=0.004) were significantly more common in females. LDL-C, HDL-C or HbA1c levels did not differ significantly between genders. The fasting blood glucose level was significantly higher (p=0.003) and hypertension was more common in females (p=0.001). There was no significant difference in an increase in physical activity or weight loss after the index event between genders, and there was no significant difference between genders regarding continuity of antiplatelet, statin, beta blocker or ACEi/ARB II receptor blocker usage (p>0.05)., Conclusion: Achievement of ideal body weight, fasting blood glucose and blood pressure targets was lower in women despite similar reported medication use. This highlights the importance of the implementation of lifestyle measures and adherence to medications in women.

Introduction: The aim of the study was to evaluate whether serum thyroid-stimulating hormone (TSH) within the normal range in euthyroid subjects (having normal free triiodothyronine (fT3) and thyroxine (fT4)) is related to the risk of overall mortality or a composite endpoint of death and nonfatal events., Material and Methods: In 614 middle-aged adult hospital screenees, free of uncontrolled diabetes at baseline, the association of sex-specific TSH tertiles with death was prospectively assessed using Cox regression, with the composite endpoint assessed using logistic regression in adjusted analyses, stratified by gender., Results: In total, 64 deaths and additional incident nonfatal events in 141 cases were recorded at a mean 7.55 years' follow-up. Multivariable linear regression revealed TSH to be significantly associated among men with age ( p = 0.006), but in women inversely with fT3 and fT4 ( p < 0.001, and p = 0.024 respectively). In logistic regression analysis, adjusted for age, fT3, fT4, systolic blood pressure and serum total cholesterol, sex-specific baseline TSH tertiles were associated in men neither with the risk of death nor with composite endpoint. In contrast, in women, the highest compared with the bottom TSH tertile predicted the risk of composite endpoint (relative risk: 2.02, 95% CI: 1.07-3.82) and, much more strongly, the mortality risk, independently of fT4 increments., Conclusions: The significant association of higher range of normal serum TSH in euthyroid middle-aged adults with the risk of death and nonfatal adverse outcomes in women alone cannot be accounted for by the action of thyroid hormone and is consistent with involvement of TSH in the pro-inflammatory state.

Objective: Bradyarrhythmia is one of the complications that may develop after cardiac surgery. Only a few studies have previously dealt with this concern, and in our study, we investigated the factors affecting the development of atrioventricular block or sinus node dysfunction and the requirement of permanent pacemaker following cardiac surgery., Methods: A total of 62 patients who developed the atrioventricular (AV) block or sinus node dysfunction and required a permanent pacemaker following cardiac surgery were included in the study. Among these, 31 patients were evaluated prospectively, and the information regarding 31 patients was evaluated retrospectively based on hospital records. Demographic, clinical, and surgical information was recorded. Patients were grouped according to the types of procedures, including the coronary artery bypass graft, valve surgery, congenital heart disease, and combinations of these. Patients were evaluated by standard 12-lead electrocardiogram and transthoracic echocardiography preoperatively. The postoperative development of bradyarrhythmia and requirement of permanent pacemaker were evaluated., Results: The mean age of patients with preoperative conduction abnormality and wide QRS was statistically significantly higher than those without these disorders. The odds ratio for preoperative conduction abnormality risk in patients over 70 years of age was found as 4.429 (95% confidence interval, 1.40-13.93). There was no gender-related statistically significant difference in terms of left ventricular ejection fraction, left ventricular dilatation, interventricular septum thickness, the time interval from operation to the development of AV block, concomitant diseases, and complication rates., Conclusion: Preoperative conduction abnormality and wide QRS in patients over 70 years of age was determined as a risk factor., Competing Interests: Conflict of Interest: The authors declare no conflict of interest.

Although low-grade inflammation has been linked to the prediction of atrial fibrillation (AF), evidence from some reports suggest that autoimmune activation might potentially be a relevant mechanism. We assessed the predictive value of inflammation and other markers for the risk of incident AF.A score of age-controlled anthropometric, lipid, and nonlipid variables was compared in participants with recorded nonvalvular persistent/permanent AF (n = 110) to those of a nested cohort sample (n = 1126) of the Turkish Adult Risk Factor study. Available values preceding by 2 (±1) years the development of AF were used regarding incident AF (n = 87) in multivariable regression.Comparing age-controlled inflammation and other markers across the 2 groups, low apolipoprotein (apo) B and total cholesterol levels differed highly significantly in each sex. Moreover, low-density lipoprotein (LDL)-cholesterol and fasting insulin concentrations were significantly lower, sex hormone binding globulin (SHBG), glucose and systolic blood pressure higher in women alone, while C-reactive protein levels were similar. A model of multivariable logistic regression analyses for overall AF and 2 models for incident AF demonstrated a consistent inverse predictive value for apoB in each gender [relative risk (RR) 0.44 (95% confidence interval (CI), 95% CI 0.30-0.66], along with age, as main determinants. SHBG in females and waist circumference in males were further significantly associated with initial AF. Never smoking (compared with ever smoking) tended to predict AF.These findings, collectively, are highly consistent with an autoimmune process in which damaged epitope of apoB due to proinflammatory state emerge as a basic mechanism in the development of AF. ApoB level is likely only apparently reduced due to partial escape from assay.

The prognostic impact of nutritional status in patients with pulmonary embolism (PE) is poorly understood. A well-accepted nutritional status parameter, prognostic nutritional index (PNI), which was first demonstrated to be valuable in patients with cancer and gastrointestinal surgery, was introduced to patients with PE. Our aim was to evaluate the predictive value of PNI in outcomes of patients with PE. We evaluated the in-hospital and long-term (53.8 ± 5.4 months) prognostic impact of PNI on 251 patients with PE. During a median follow-up of 53.8 ± 5.4 months, 27 (11.6%) patients died in hospital course and 31 (13.4%) died in out-of-hospital course. The patients with lower PNI had significantly higher in-hospital and long-term mortality. The Cox proportional hazard analyses showed that PNI was associated with an increased risk of all-cause death for both unadjusted model and adjusted for all covariates. Our study demonstrated that PNI, calculated based on serum albumin level and lymphocyte count, is an independent prognostic factor for mortality in patients with PE.

Objectives: The prognostic effects of poor nutritional status and cardiac cachexia on coronary artery disease (CAD) are not clearly understood. A well-accepted nutritional status parameter, the prognostic nutritional index (PNI), which was first demonstrated to be valuable in patients with cancer and those undergoing gastrointestinal surgery, was introduced to patients requiring coronary artery bypass grafting (CABG). The aim of the present study was to evaluate the prognostic value of PNI in patients with CAD undergoing CABG., Methods: We evaluated the in-hospital and long-term (3-y) prognostic effect of PNI on 644 patients with CAD undergoing CABG. Baseline characteristics and outcomes were compared among the patients by PNI and categorized accordingly: Q1, Q2, Q3, and Q4., Results: Patients with lower PNI had significantly higher in-hospital and long-term mortality. Patients with lower PNI levels (Q1) had higher in-hospital mortality and had 12 times higher mortality rates than those with higher PNI levels (Q4). The higher PNI group had the lower rates and was used as the reference. Long-term mortality was higher in patients with lower PNI (Q1)-4.9 times higher than in the higher PNI group (Q4). In-hospital and long-term mortality rates were similar in the non-lower PNI groups (Q2-4)., Conclusion: The present study demonstrated that PNI, calculated based on serum albumin level and lymphocyte count, is an independent prognostic factor for mortality in patients undergoing CABG., (Copyright © 2017 Elsevier Inc.

Objective: Iron deficiency (ID) is the most common nutritional deficiency, and iron metabolism becomes further deteriorated in the presence of certain conditions, such as heart failure (HF). Atrial fibrillation (AF) has many similarities to HF, including a chronic inflammatory pathophysiology; however, the prevalence of ID and other hematinic deficiencies in AF patients have not been determined., Methods: In this study, the prevalence of iron (serum ferritin <100 µg/L or ferritin 100-299 µg/L with transferrin saturation <20%), vitamin B12 (<200 pg/mL), and folate deficiency (<4.0 ng/mL) was evaluated in 101 patients with non-valvular AF with preserved left ventricular ejection fraction and no signs of HF, and the results were compared with 35 age- and gender-matched controls., Results: Anemia was detected in 26% of the patients. A total of 48 (47.6%) patients had ID, 10 (9.9%) had a vitamin B12 deficiency, and 13 (12.9%) had a folate deficiency. The prevalence of ID was similar in the controls and the paroxysmal AF patients, but increased gradually in persistent and permanent AF. Univariate logistic regression analysis demonstrated that permanent vs. paroxysmal AF [Odds ratio (OR): 2.17; 95% confidence interval (CI): 0.82-5.69; p=0.011], high sensitive C-reactive protein (OR: 1.47; 95% CI: 0.93-2.36; p=0.019), N-terminal pro b-type natriuretic peptide (OR: 1.24; 95% CI: 0.96-1.71; p=0.034), and white blood cell count (OR: 1.21; 95% CI: 0.95-1.58; p=0.041) were associated with ID. In multivariable analysis, permanent AF remained as an independent clinical associate of ID (OR: 4.30; 95% CI: 0.83-12.07; p=0.039)., Conclusion: ID is common in permanent AF, as in HF. Inflammation and neurohormonal activation seem to contribute to its development.

The Src tyrosine kinase family contributes to the signalling mechanism mediating serotonin (5-hydroxytryptamine (5-HT))-induced vasoconstriction. These kinases were reported to influence the calcium sensitivity of the contractile apparatus. Whether Src kinases affect also the intracellular calcium concentration during constriction of intact arteries is unknown. Thus, we tested the hypothesis that constriction of arteries is associated with a Src kinase-dependent alteration of the intracellular calcium concentration. Contractility of gracilis arteries of Wistar rats was studied using isometric and isobaric myography. The intracellular calcium concentration was measured simultaneously with tension by FURA-2 fluorimetry. Inhibition of Src kinases with 10 μM PP2, 30 μM dasatinib and 100 μM AZM 475271 resulted in a strong attenuation of 5-HT-induced contractions. Vessel incubation with 10 μM PP3, an inactive analogue of PP2, had no effect. Removal of the endothelium did not alter vessel contractile responses to 5-HT nor the action of the Src-kinase inhibitor PP2. The PP2-mediated inhibition of 5-HT-induced contraction was associated with a reduced response of [Ca 2+ ] i to 5-HT. In particular, inhibition of Src kinases attenuates 5-HT-induced calcium influx as well as calcium release from intracellular stores. In contrast, the calcium sensitivity of the contractile apparatus and the filling state of the sarcoplasmic reticulum were not influenced by Src kinases during 5-HT-induced contractions. We conclude that Src kinase activation is a powerful mechanism to produce vasoconstriction of small skeletal muscle arteries of rats. This effect is endothelium-independent. The data further suggest that the action of c-Src kinases is associated with a change in the intracellular calcium concentration that involves Ca 2+ entry and Ca 2+ release pathways.

Objective: New oral anticoagulants (NOACs) are increasingly used both for prevention of stroke in non-valvular atrial fibrillation (NVAF) and the treatment of venous thromboembolism (VTE). In this study, we aimed to evaluate the current patterns of NOACs treatment in Turkey. Moreover, demographic and clinical parameters and bleeding and/or embolic events under NOACs treatment were analyzed., Methods: The New Oral Anticoagulants-TURKey (NOAC-TURK) study was designed as a multicenter cross-sectional study. A total of 2,862 patients from 21 different centers of Turkey under the treatment of NOACs for at least three months were included in this study. Demographic, clinical, and laboratory characteristics of study participants with their medications used were obtained through the NOAC-TURK survey database. Additional necessary medical records were obtained from electronic health records of participating centers., Results: Of the 2. 862 patients, 1.131 (39.5%) were male and the mean age was 70.3±10.2 years. Hypertension was found as the most frequent comorbidity (81%). The most common indication for NOACs was permanent atrial fibrillation (83.3%). NOACs were mainly preferred because of inadequate therapeutic range or overdose during warfarin usage. The most frequent complication was bleeding (n=217, 7.6%), and major bleeding was observed in 1.1% of the patients. Embolic events were observed in 37 patients (1.3%). Rivaroxaban and dabigatran were both more preferred than apixaban. Almost half of the patients (47.6%) were using lower doses of NOACs, which is definitely much more than expected., Conclusion: The NOAC-TURK study showed an important overview of the current NOACs treatment regimens in Turkey. Although embolic and bleeding complications were lower than or similar to previous studies, increased utilization of low-dose NOACs in this study should be considered carefully. According to the results of this study, NOACs treatment should be guided through CHA2DS2-VASc and HASBLED scores to ensure more benefit and less adverse effects in NVAF patients.

Objective: Data from EUROASPIRE-IV Turkey report investigating risk factors and adherence to guidelines in patients hospitalized for coronary artery disease are presented and results are compared with those of EUROASPIRE-III Turkey and EUROASPIRE-IV Europe., Methods: Study was performed in 24 European countries, including Turkey (17 centers). Patients (18-80 years old) hospitalized for coronary (index) event during preceding 3 years were identified from hospital records and interviewed ≥6 months later. Patient information regarding index event was acquired from hospital records. Anamnesis was obtained during the interview, and physical examination and laboratory analyses were performed., Results: Median age at the index coronary event was 58.8 years, and it was significantly decreased compared with last EUROASPIRE-III study (60.5 years), which was conducted at the same centers 6 years earlier (p=0.017). Of all patients, 19.3% were under 50 years of age and mean age was lower than that of EUROASPIRE-IV Europe (62.5 years). Comparing EUROASPIRE-IV Turkey with EUROASPIRE-III Turkey, rate of smokers increased to 25.5% from 23.1% (p=0.499), obesity increased to 40.7% from 35.5% (p=0.211), total cholesterol level increased to 49.6% from 48.3% (p=0.767), and diabetes rate increased to 39.7% from 33.6% (p=0.139), however none of the differences reached a level of statistical significance. Only 11.7% of the smokers quit after coronary event. Rates for these factors were lower in EUROASPIRE-IV Europe (16% for smoking, 37.6% for obesity, and 26.8% for diabetes)., Conclusion: EUROASPIRE-IV Turkey data revealed that secondary prevention was unsatisfactory and had progressed unfavorably compared with last EUROASPIRE study, some risk factors were more uncontrolled than overall European average, and coronary artery events at young age remain an important problem.

Objective: A predictive role of serum Pentraxin 3 (PTX3) for short-term adverse cardiovascular events including mortality in acute myocardial infarction (AMI) was reported in recent studies. The aim of the study was to investigate long-term prognostic significance of serum PTX3 in an AMI with 5-year follow-up period in this study., Methods: In this prospective study, 140 patients, who were admitted to the emergency department between January 2011 and December 2011 with acute chest pain and/or dyspnea and diagnosed with AMI and 60 healthy controls were included. PTX3 levels were measured at admission by using an ELISA method. The study group was divided into tertiles on the basis of admission PTX3 values: the high-PTX3 group (≥4.27 ng/mL), the middle-PTX3 groups (4.27-1.63 ng/mL), and the low-PTX3 group (≤1.63 ng/mL)., Results: PTX3 level was significantly more greatly increased in the AMI group than in the controls (2.27±0.81 vs. 0.86±0.50 ng/mL, p<0.001). PTX3 level was found to be significantly positively correlated with TIMI score (r=0.368, p=0.037), high sensitive C-reactive protein (hsCRP) (r=0.452, p=0.024), pro-BNP (r=0.386, p=0.029), troponin I (r=0.417, p=<0.001), and GRACE score (r=0.355, p=0.045), and negatively correlated with HDL cholesterol (r=-0.203, p=0.016) and LVEF (r=-0.345, p=0.028). In multivariate analysis, PTX3 (OR=1.12, 95% CI 1.04-1.20; p=0.001) was a significant independent predictor of long-term cardiovascular mortality, after adjusting for other risk factors., Conclusion: PTX3 is a novel biomarker that may help to identify high risk individuals with AMI, who are potentially at risk of early major adverse cardiovascular events including mortality in the long-term period.

Objective: We investigated the possible association of serum acylation stimulating protein (ASP) with cardiometabolic disorders and the evidence of autoimmune activation., Methods: Population-based randomly selected 1024 participants were cross-sectionally and prospectively analyzed. ASP concentrations were measured with a validated ELISA kit. Correlations were sought separately in subjects with no cardiometabolic disorders (n=427) designated as "healthy.", Results: ASP was positively correlated with total testosterone and inversely correlated with platelet activating factor (PAF), PAF-acetylhydrolase (AH), in each gender, and positively correlated in "healthy" men with lipoprotein [Lp](a) and apolipoprotein B. Correlations of ASP with PAF values ≥22 nmol/L were abolished, contrasted to a strongly inverse one in subjects with PAF <22 nmol/L. In linear regression analyses in the whole sample, ASP was inversely associated independently with PAF and PAF-AH and, in men, positively with Lp(a) and sex hormone-binding globulin. Prevalent and (at 2.0 years' follow-up) incident metabolic syndrome (MetS, n=393), diabetes (n=154), and coronary heart disease (CHD, n=171) were analyzed by sex-, age-, and Lp(a)-adjusted logistic regression, using tertiles of ASP and PAF. The lower two (<42 nmol/L) ASP tertiles were a risk factor in combined sexes for MetS and diabetes. In women, incident CHD was predicted by either reduced or elevated ASP tertiles., Conclusion: Findings can be explained by the notion of operation of immune responses against both ASP and oxidized PAF-like lipids of Lp(a) to yield for "reduced" values and increased likelihood of cardiometabolic disorders.

Bronchobiliary fistula (BBF) is a rare condition in which an abnormal communication exists between the bile ducts and the bronchial tree. Malignancy is the most common etiology of BBF, although many others are possible. A 74-year-old male patient with an inoperable Klatskin tumor presented with a complaint of yellow-green sputum and cough; the patient underwent fiber-optic bronchoscopy based on a preliminary diagnosis of bronchobiliary fistula. Using fiber-optic rigid bronchoscopy, the laterobasal segment of the lower right lung lobe was occluded using three pieces of 5-mm Endobronchial Watanabe Spigot. Bile drainage subsequently ceased. A bronchoscopic approach provides an alternative option for BBF treatment, particularly in patients who choose not to undergo surgery, or for whom surgery is not an option due to their underlying general condition.
