1. Enhancing Wear Resistance and Mechanical Behaviors of AA7020 Alloys Using Hybrid Fe3O4-GNP Reinforcement

Author: Ufuk Taşcı, Taha Alper Yılmaz, Halil Karakoç, and Şener Karabulut
Subjects: AA7020-GNP composites, milling duration effects, wear resistance improvement, mechanical property, Science
Abstract: This study investigates the effect of graphene nanoplatelets (GNPs) and milling duration on the microstructure, mechanical properties, and wear resistance of the AA7020 alloy reinforced with Fe3O4 and GNP. The composites were prepared with a fixed 10 wt.% Fe3O4 and varying GNP contents (0.5 and 1 wt.%) using high-energy ball milling for 4 and 8 h, followed by hot pressing. The aim was to enhance the performance of the AA7020 alloy for potential use in defense, automotive, aviation, and space applications, where superior mechanical properties and wear resistance are required. The results showed that the incorporation of 0.5 wt.% GNP and optimized milling significantly improved the composite’s performance. The AA7020 + 10 wt.% Fe3O4 + 0.5 wt.% GNP composite achieved the highest density (99.70%) when milled for 4 h. Its hardness increased with both the inclusion of GNP and extended milling duration, with the composite milled for 8 h exhibiting the highest hardness value (149 HBN). The tensile strength also improved, with the composite milled for 4 h showing a 28% increase (292 MPa) compared with the unreinforced alloy. Additionally, the friction coefficient decreased with GNP content and milling duration, with the composite milled for 8 h showing a 26% reduction. Wear resistance was notably enhanced, with the composite milled for 8 h exhibiting the lowest specific wear rate (7.86 × 10−7 mm3/Nm).

Abstract: Aluminum alloys have advanced to meet the growing demand for strong, lightweight materials. The 2219 aluminum alloy has gained popularity due to its superior mechanical properties and high copper content. However, despite these improvements, the wear characteristics of metal matrix composites with ceramic reinforcements have been suboptimal. This study aims to develop metal matrix composites that improve the mechanical and wear properties of AA2219 aluminum alloy. A homogeneous mixture was created using a 3D mechanical mixer/miller apparatus. ZrO2 and B4C reinforcements were added to the matrix in ratios of 5%, 10%, and 15%, including hybrid composites with both reinforcements. Mechanical and wear characteristics were analyzed, and a 3D profilometer was used to evaluate wear properties and determine tribological parameters. The results showed that the pulverized reinforcement particles were uniformly dispersed within the matrix. The sample with a hybrid reinforcement comprising 15% of the total composition exhibited the highest hardness, measuring 164.96 hV. This study demonstrates that incorporating ceramic reinforcements in specific ratios can significantly enhance the mechanical and wear properties of 2219 aluminum alloy composites.

10. Enhancing Wear Resistance and Mechanical Behaviors of AA7020 Alloys Using Hybrid Fe 3 O 4 -GNP Reinforcement.

Author: Taşcı, Ufuk, Yılmaz, Taha Alper, Karakoç, Halil, and Karabulut, Şener
Subjects: MECHANICAL wear, WEAR resistance, IRON oxides, ALLOYS
Abstract: This study investigates the effect of graphene nanoplatelets (GNPs) and milling duration on the microstructure, mechanical properties, and wear resistance of the AA7020 alloy reinforced with Fe3O4 and GNP. The composites were prepared with a fixed 10 wt.% Fe3O4 and varying GNP contents (0.5 and 1 wt.%) using high-energy ball milling for 4 and 8 h, followed by hot pressing. The aim was to enhance the performance of the AA7020 alloy for potential use in defense, automotive, aviation, and space applications, where superior mechanical properties and wear resistance are required. The results showed that the incorporation of 0.5 wt.% GNP and optimized milling significantly improved the composite's performance. The AA7020 + 10 wt.% Fe3O4 + 0.5 wt.% GNP composite achieved the highest density (99.70%) when milled for 4 h. Its hardness increased with both the inclusion of GNP and extended milling duration, with the composite milled for 8 h exhibiting the highest hardness value (149 HBN). The tensile strength also improved, with the composite milled for 4 h showing a 28% increase (292 MPa) compared with the unreinforced alloy. Additionally, the friction coefficient decreased with GNP content and milling duration, with the composite milled for 8 h showing a 26% reduction. Wear resistance was notably enhanced, with the composite milled for 8 h exhibiting the lowest specific wear rate (7.86 × 10−7 mm3/Nm). [ABSTRACT FROM AUTHOR]

Abstract: INTRODUCTION[|]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.[¤]DISCUSSION AND CONCLUSION[|]Preoperative conduction abnormality and wide QRS in patients over 70 years of age was determined as a risk factor.[¤]

Abstract: Background: Atrial fibrillation is the most common clinically significant arrhythmia. It is now established that atrial high-rate episodes are highly correlated with atrial fibrillation. Aims: To investigate the relation between diastolic electrocardiographic parameters and subclinical atrial fibrillation detected by cardiac implantable electronic devices. Study Design: Ccross-sectional study. Methods: A total of 203 patients who had a dual-chamber, rate-modulated pacing pacemaker implanted due to sinus node dysfunction were prospectively enrolled in this study. Atrial high-rate episodes were defined as any lasting more than 5 min with an atrial rate of ≥220 beats per minute during the previous year. Patient groups were categorized on the basis of pacemaker interrogation as the absence of atrial high-rate episodes [atrial high-rate episodes (-)] and the presence of atrial high-rate episodes [atrial high-rate episodes (+)]. Episodes related to atrial over sensing were excluded. Twelve-lead surface electrocardiography was independently analyzed by two experienced readers for the measurement of diastolic electrocardiography parameters. Results: Among 203 patients (mean age: 67.5±9.1, 60.1% male), 51 (25.1%) with atrial high-rate episodes were defined as group 1 and 152 (74.9%) without atrial high-rate episodes were defined as group 2. Both groups were similar in terms of demographic characteristics and cardiovascular risk factors. Tend-Q and Tend-P were significantly longer in group 2. PQ interval was statistically longer in group 1. Corrected QT interval was significantly longer in group 1. Diastolic electrocardiography index, heart rate and PQ and QT intervals were the only independent predictors of atrial high-rate episodes in patients with dual pacemakers in multivariate analysis. Conclusion: Abnormal diastolic electrocardiography parameters are powerful predisposing factors for the initiation of incident atrial fibrillation. Diastolic electrocardiography parameters and a novel diastolic index predict atrial high-rate episodes. Evaluating these parameters enables clinicians to identify patients who are at high risk and who may benefit from prophylactic treatment

Abstract: INTRODUCTION[|]Postoperative atrial fibrillation (POAF) is a frequent and serious complication after aorto-coronary bypass graft (ACBG) surgery which unfortunately increases morbidity and mortality. Postoperative stroke, hemodynamic instability, renal failure, infection, inotropic agent and coronary unit need are complications caused by POAF. Inflammation and oxidative stress are among several mechanisms contributing to the pathogenesis of POAF. Monocyte to HDL ratio (M/H ratio) is a newly defined parameter of both inflammation and oxidative stress. In this study we investigated M/H ratio in predicting POAF after ACBG surgery.[¤]METHODS[|]Total number of 311 patients who underwent ACBG surgery were included in our study. Blood samples were obtained from the patients after 12 hours of fasting for analysis of routine biochemistry and lipid panel in the morning of ACBG surgery. Patients were monitored for the occurrence of POAF continuously through hospitalization. [¤]RESULTS[|]POAF was demonstrated in 71 patients after ACBG operation. M/H ratio was significantly higher in POAF+ group compared to POAF – group (p< 0.001). Median age of POAF (+) patients is 62.0+-10.1 which was significantly higher than POAF (-) patients. Other atrial fibrillation risk factors such as hypertension, diabetes mellitus, smoking or alcohol consumption were similar between groups. Potassium level was statistically lower in POAF+ group compared to POAF- group. (p= 0,01)[¤]DISCUSSION AND CONCLUSION[|]M/H ratio is an indicator of inflammation and oxidative stress which both plays an important role in the pathogenesis of atrial fibrillation. M/H ratio was found be statistically higher in POAF + patients compared to POAF – patients.[¤]

Abstract: Objective: Extracorporeal shock wave lithotripsy (ESWL) is a safe and effective treatment for urinary tract calculi. While serious side effects are rare, transient cardiac arrhythmias may occur. New electrocardiographic (ECG) parameters, such as P wave dispersion (PWD), QT dispersion (QTd), T peak to T end (Tp-e) interval, Tp-e interval/QT ratio, and Tp-e interval/corrected QT ratio have been defined to help predict atrial and ventricular arrhythmias. However, effect of ESWL on these ECG parameters has not been previously investigated. The present study was an examination of the effect of ESWL on ECG parameters. Methods: Total of 40 consecutive patients who underwent ESWL were prospectively enrolled in the study. Pre-procedure ECG parameters were compared with post-procedure ECG parameters. Results: PWD values were significantly longer on post-procedure ECG compared with pre-procedure ECG (p=0.017). Corrected QT duration and QTd were significantly longer on post-procedure ECG compared with pre-procedure ECG (p=0.046 and p=0.008, respectively). In addition, Tp-e interval, Tp-e interval/QT ratio, and Tp-e interval/QTc ratio were significantly longer post procedure (p=0.035, p=0.045, and p=0.022, respectively). In univariate correlation analysis, duration of procedure was significantly correlated with post-procedure PWD, QTc, and QTD values. Conclusion: Clinical use of ECG parameters may be helpful in monitoring of patients receiving ungated ESWL in order to detect cardiac dysrhythmia.

Abstract: INTRODUCTION[|]Red cell distribution width (RDW) and neutrophil to lymphocyte ratio (NLR) have been found to be associated with non-valvular atrial fibrillation (AF) and cardiovascular diseases. However, correlation of these parameters with presence of left atrial (LA) thrombus and/or spontaneous echo contrast (SEC) in patients with non-valvular AF has not been clarified. This study was an investigation of correlation of RDW, NLR, and clinical risk factors with LA thrombus and dense SEC in patients with non-valvular AF in the Turkish population.[¤]METHODS[|]The demographic, laboratory, and echocardiographic properties of 619 non-valvular AF patients who underwent transesophageal echocardiography (TEE) examination before direct current cardioversion (DCCV) or AF ablation treatment were retrospectively investigated. Complete blood count (CBC) and biochemical parameters were studied 6 to 12 hours before TEE examination. Left atrial stasis (LAS) markers were noted as presence of left atrial/left atrial appendage (LA/LAA) thrombus or dense spontaneous echo contrast (DSEC).[¤]RESULTS[|]Total of 325 (52%) patients with LAS were compared with 294 patients (48%) without LAS. In the LAS group, there were 274 (84%) patients with LA/LAA thrombus and 51 (16%) patients with DSEC. LAS (+) group, values for RDW (14.85+-1.48 vs. 13.77+-1.30; p6 months, and international normalized ratio

Abstract: Background Clinical complexity is increasingly prevalent among patients with atrial fibrillation (AF). The ‘Atrial fibrillation Better Care’ (ABC) pathway approach has been proposed to streamline a more holistic and integrated approach to AF care; however, there are limited data on its usefulness among clinically complex patients. We aim to determine the impact of ABC pathway in a contemporary cohort of clinically complex AF patients. Methods From the ESC-EHRA EORP-AF General Long-Term Registry, we analysed clinically complex AF patients, defined as the presence of frailty, multimorbidity and/or polypharmacy. A K-medoids cluster analysis was performed to identify different groups of clinical complexity. The impact of an ABC-adherent approach on major outcomes was analysed through Cox-regression analyses and delay of event (DoE) analyses. Results Among 9966 AF patients included, 8289 (83.1%) were clinically complex. Adherence to the ABC pathway in the clinically complex group reduced the risk of all-cause death (adjusted HR [aHR]: 0.72, 95%CI 0.58–0.91), major adverse cardiovascular events (MACEs; aHR: 0.68, 95%CI 0.52–0.87) and composite outcome (aHR: 0.70, 95%CI: 0.58–0.85). Adherence to the ABC pathway was associated with a significant reduction in the risk of death (aHR: 0.74, 95%CI 0.56–0.98) and composite outcome (aHR: 0.76, 95%CI 0.60–0.96) also in the high-complexity cluster; similar trends were observed for MACEs. In DoE analyses, an ABC-adherent approach resulted in significant gains in event-free survival for all the outcomes investigated in clinically complex patients. Based on absolute risk reduction at 1 year of follow-up, the number needed to treat for ABC pathway adherence was 24 for all-cause death, 31 for MACEs and 20 for the composite outcome. Conclusions An ABC-adherent approach reduces the risk of major outcomes in clinically complex AF patients. Ensuring adherence to the ABC pathway is essential to improve clinical outcomes among clinically complex AF patients.

Abstract: © 2023 Elsevier LtdIn this study, nano B4C powder metal composite samples reinforced in WE43 matrix with different ratios (0.25, 0.5, 1 and 2 wt%) were produced by hot pressing method. The composite powders were mixed at 300 rpm for 4 h and produced by pressing under 350 MPa pressure in a hot pressing unit at 525 °C for 90 min. XRD, optical microscope and SEM-EDS devices were used for the characterization processes of nano B4C reinforced composite samples. Microhardness, transverse rupture strength and wear were applied to determine the mechanical properties. It was determined that the highest hardness, transverse rupture strength and lowest wear rate were in WE43/2% nano B4C composite sample.

Abstract: The coronary sinus, whose electrical features play an important role in cardiac arrhythmias, is the integral part of the cardiac venous system. Here we describe a 67-year-old male patient with congestive heart failure who was referred to our hospital after the failure of the first cardiac resynchronization therapy defibrillator (CRT-D) implantation. During the cannulation of the coronary sinus, the separate orifice of the posterior cardiac vein was demonstrated by the retrograde filling of the coronary sinus via contrast injection into the posterior cardiac vein. Due to the serious tortuosity of the coronary venous sinus, a multipolar left ventricular lead was implanted using the separate ostium of the posterior cardiac vein. In our patient, the posterior cardiac vein directly drained into the right atrium. At 3 months’ follow-up with the CRT-D, he was asymptomatic (New York Heart Association functional class I).

Abstract: Background: Atrial fibrillation (AF) and renal impairment share a bidirectional relationship with important pathophysiological interactions. We evaluated the impact of renal impairment in a contemporary cohort of patients with AF. Methods: We utilised the ESC-EHRA EORP-AF Long-Term General Registry. Outcomes were analysed according to renal function by CKD-EPI equation. The primary endpoint was a composite of thromboembolism, major bleeding, acute coronary syndrome and all-cause death. Secondary endpoints were each of these separately including ischaemic stroke, haemorrhagic event, intracranial haemorrhage, cardiovascular death and hospital admission. Results: A total of 9306 patients were included. The distribution of patients with no, mild, moderate and severe renal impairment at baseline were 16.9%, 49.3%, 30% and 3.8%, respectively. AF patients with impaired renal function were older, more likely to be females, had worse cardiac imaging parameters and multiple comorbidities. Among patients with an indication for anticoagulation, prescription of these agents was reduced in those with severe renal impairment, p 2 decrease), that was most notable in patients with eGFR 2 (HR 2.21 [95% CI, 1.23–3.99] compared to eGFR ≥90 ml/min/1.73 m 2). Conclusion: A significant proportion of patients with AF suffer from concomitant renal impairment which impacts their overall management. Furthermore, renal impairment is an independent predictor of major adverse events including thromboembolism, major bleeding, acute coronary syndrome and all-cause death in patients with AF.

23. Microstructure evolution and wear properties of ECAP-treated Al-Zn-Mg alloy: Effect of route, temperature and number of passes

Author: Taha Alper Yilmaz, Yasar Totik, Guzide Meltem Lule Senoz, and Bulent Bostan
Subjects: Mechanics of Materials, Materials Chemistry, General Materials Science
Abstract: In this study, the effect of severe plastic deformation on Al-Zn-Mg alloy was investigated by ECAP method. The ECAP process parameters were determined using Taguchi experimental design for different routes (A, BC and C), different temperatures (100, 150 and 200 degrees C) and different number of passes (2, 4 and 8). EBSD and TEM analysis were used for microstructural characterization of the samples and the dry sliding wear test was used to measure the mechanical strength. In the study of microstructural properties, it was determined that there was a direct relationship between the number of passes and temperature. With the increase in the number of passes and the decrease in the temperature, a severe decrease in grain size in the samples was observed. It was observed that the sample subjected to ECAP treatment with 8 passes at 100 degrees C in the BC route was microstructurally coaxial and had the smallest grain size, and the same sample showed the best wear properties.

Subjects: apixaban, atrial fibrillation, hypertrophic cardiomyopathy, thrombus., Medicine, Internal medicine, RC31-1245, Diseases of the circulatory (Cardiovascular) system, RC666-701
Abstract: Summary– Anticoagulation with warfarin is the main treatment of intracardiac thrombus. While novel oral anticoagulants (NOACs) have been approved by the US Food and Drug Administration (FDA) for stroke prevention in patients with nonvalvular atrial fibrillation (AF), they are not indicated for resolution of intracardiac thrombus. The case of a 60-year-old woman with left ventricular (LV) thrombus secondary to hypertrophic cardiomyopathy and AF is described in the present report. Indications for oral anticoagulation were AF and LV thrombus. Thrombus was dissolved after 1 month of apixaban treatment. To the best of our knowledge, this is the first report that describes the resolution of LV thrombus with apixaban treatment in a patient with hypertrophic cardiomyopathy.

Abstract: Background Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent. Objectives We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients. Methods A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined. Results Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55–0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty. Conclusions In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

30. Subclavian vein puncture-induced massive pulmonary hemorrhage and hemoptysis during pacemaker implantation

Author: Nizamettin Selcuk Yelgec, Altug Osken, Ceyhan Turkkan, and Ahmet Taha Alper
Subjects: hemoptysis, pacemaker, pulmonary hemorrhage., Medicine, Medicine (General), R5-920
Abstract: We present a rare and interesting case of subclavian vein puncture-induced focal intraparenchymal lung hemorrhage and massive hemoptysis developed during CRT-D implantation. Clinical picture advanced to pulmonary edema in seconds. A noncontrast multiple-detector computed tomography scan revealed focal alveolar hemorrhage in the lung tissue right under the pacemaker pocket, but remarkably, there was no pneumothorax. This case shows that if cough and hemoptysis suddenly develop during subclavian puncture, injury of the adjoining lung because of parenchymal puncture should be considered as a complication.

32. Immediate electrical storm of Torsades de Pointes after CRT-D implantation in an ischemic cardiomyopathy patient

Abstract: Cardiac resynchronization therapy with an implantable cardioverter-defibrillator (CRT-D) is the preferred treatment for patients with severe heart failure, dyssynchrony, and an increased risk of sudden cardiac death or for primary ventricular arrhythmia survivors. Rarely, left ventricular epicardial pacing can induce ventricular tachyarrhythmia rather than a beneficial effect. We describe an ischemic cardiomyopathy patient who underwent CRT-D therapy and developed sustained torsades de pointes (TdP) immediately after switching to biventricular pacing (BVP) mode. Here, TdP possibly developed owing to the change in the dispersion of repolarization of the left ventricle myocardium. The diagnosis and management of BVP-induced ventricular arrhythmia is discussed.

Abstract: Aims The 4S-AF classification scheme comprises of four domains: stroke risk (St), symptoms (Sy), severity of atrial fibrillation (AF) burden (Sb), and substrate (Su). We sought to examine the implementation of the 4S-AF scheme in the EORP-AF General Long-Term Registry and compare outcomes in AF patients according to the 4S-AF-led decision-making process. Methods and results Atrial fibrillation patients from 250 centres across 27 European countries were included. A 4S-AF score was calculated as the sum of each domain with a maximum score of 9. Of 6321 patients, 8.4% had low (St), 47.5% EHRA I (Sy), 40.5% newly diagnosed or paroxysmal AF (Sb), and 5.1% no cardiovascular risk factors or left atrial enlargement (Su). Median follow-up was 24 months. Using multivariable Cox regression analysis, independent predictors of all-cause mortality were (St) [adjusted hazard ratio (aHR) 8.21, 95% confidence interval (CI): 2.60–25.9], (Sb) (aHR 1.21, 95% CI: 1.08–1.35), and (Su) (aHR 1.27, 95% CI: 1.14–1.41). For CV mortality and any thromboembolic event, only (Su) (aHR 1.73, 95% CI: 1.45–2.06) and (Sy) (aHR 1.29, 95% CI: 1.00–1.66) were statistically significant, respectively. None of the domains were independently linked to ischaemic stroke or major bleeding. Higher 4S-AF score was related to a significant increase in all-cause mortality, CV mortality, any thromboembolic event, and ischaemic stroke but not major bleeding. Treatment of all 4S-AF domains was associated with an independent decrease in all-cause mortality (aHR 0.71, 95% CI: 0.55–0.92). For each 4S-AF domain left untreated, the risk of all-cause mortality increased substantially (aHR 1.35, 95% CI: 1.16–1.56). Conclusion Implementation of the novel 4S-AF scheme is feasible, and treatment decisions based on this scheme improve mortality rates in AF.

Abstract: In the present study, graphene nanosheets were synthesised by liquid phase exfoliation process, and the obtained graphene was reinforced in the rates of 0.1, 0.2, 0.3 and 0.6 wt.%. After the composites were characterised, they were exposed to Equal Channel Angular Pressing (ECAP) process. While 0.1 wt.% and 0.2 wt.% graphene reinforced composite samples successfully completed the ECAP process, 0.1 wt.% and 0.2 wt.% graphene reinforced composite samples were broken during the ECAP process. Electrical, thermal, and mechanical properties of the composite increased with the increased amount of graphene. The mechanical properties of ECAP-processed samples showed significant increases compared to non-ECAP processed samples. To figure out the effect of the ECAP process, moulds with different channel angles were used, the ECAP temperature was changed, and different passes were performed and the angles of 120° and 90° were used. ECAP-processed samples in both mould angles showed similar mechanical properties. With the increasing ECAP temperature, the mechanical properties of the sample decreased, but its electrical conductivity increased. As the number of passes increased, mechanical properties increased and crack formation in material increased. In addition, it was not possible to successfully remove the matrix composites containing more than 0.3 wt.% graphene from the ECAP process. Especially in the sample containing 0.6 wt.% graphene, brittle fractures were seen during the ECAP process and the sample was divided into many parts. The results showed that the composite responded better to the ECAP process when low amounts of graphene were reinforced in the al matrix. Significant improvements were observed in the properties of these composites after the ECAP process. In this study, the properties of composites with and without ECAP process were extensively investigated. The results were compared in detail with the previous studies. The graphene was produced using a simple method and it was reinforced with the Al matrix with the easiest possible method.

Abstract: The use of cardiac resynchronization therapy (CRT) has become widespread in patients with heart failure who meet the criteria for implantation. Coronary sinus lead positioning is important to provide the intended biventricular stimulation. Diaphragm pacing is a lead-related complication which occurs secondary to phrenic nerve stimulation. We present the case of a 58-year-old male patient who had diaphragm pacing after CRT with defibrillator implantation. The complication was resolved by using the transvenous femoral approach with the wrapping method.

37. Spinor Boson Droplets Stabilized By Spin Fluctuations

Abstract: Self-trapped droplets stabilized by quantum fluctuations have been experimentally realized in dipolar gases and binary Boson mixtures. We propose spinor Bose gases as another candidate for droplet formation in this work. For spin-1 gas, we find that spin fluctuations give a dilute but self-trapped state for two different order parameters where the mean-field picture predicts collapse. A polar droplet phase can be stabilized by spin fluctuations for both antiferromagnetic and ferromagnetic spin-dependent coupling. An antiferromagnetic droplet phase can be stabilized similarly with a negative quadratic Zeeman shift. Furthermore, the beyond mean-field energy of the system depends on the quadratic Zeeman coupling, which provides a mechanism to tune the droplet formation and its density. We discuss the parameters necessary for the experimental realization of such spinor droplets., Comment: 8 pages, 4 figures

Abstract: Background Epidemiological studies in atrial fibrillation (AF) illustrate that clinical complexity increase the risk of major adverse outcomes. We aimed to describe European AF patients’ clinical phenotypes and analyse the differential clinical course. Methods We performed a hierarchical cluster analysis based on Ward’s Method and Squared Euclidean Distance using 22 clinical binary variables, identifying the optimal number of clusters. We investigated differences in clinical management, use of healthcare resources and outcomes in a cohort of European AF patients from a Europe-wide observational registry. Results A total of 9363 were available for this analysis. We identified three clusters: Cluster 1 (n = 3634; 38.8%) characterized by older patients and prevalent non-cardiac comorbidities; Cluster 2 (n = 2774; 29.6%) characterized by younger patients with low prevalence of comorbidities; Cluster 3 (n = 2955;31.6%) characterized by patients’ prevalent cardiovascular risk factors/comorbidities. Over a mean follow-up of 22.5 months, Cluster 3 had the highest rate of cardiovascular events, all-cause death, and the composite outcome (combining the previous two) compared to Cluster 1 and Cluster 2 (all P < .001). An adjusted Cox regression showed that compared to Cluster 2, Cluster 3 (hazard ratio (HR) 2.87, 95% confidence interval (CI) 2.27–3.62; HR 3.42, 95%CI 2.72–4.31; HR 2.79, 95%CI 2.32–3.35), and Cluster 1 (HR 1.88, 95%CI 1.48–2.38; HR 2.50, 95%CI 1.98–3.15; HR 2.09, 95%CI 1.74–2.51) reported a higher risk for the three outcomes respectively. Conclusions In European AF patients, three main clusters were identified, differentiated by differential presence of comorbidities. Both non-cardiac and cardiac comorbidities clusters were found to be associated with an increased risk of major adverse outcomes.

Abstract: AA7075 Al alloys are widely used in the aerospace industry. However, the mechanical properties of these alloys are insufficient in space conditions. AA7075 Al alloy is produced by powder metallurgy method due to the good wear properties. Then AA7075 Al alloys have to be adapted to mechanical properties MoS2-TiB2 composite films are deposited. MoS2-TiB2 composite films were grown on powder metal substrate using CFUBMS method in three different MoS2 target currents. Structural properties of composite films were analyzed by SEM, XRD and XPS methods. The mechanical properties of the films are carried out by microhardness and scratch tester. The best grade value of AA7075 powder metal alloy was made with 800MPa pressing pressure and increased from 2.61g/cm3 to 2.72g/cm3 after sintering. The highest hardness was obtained at the lowest MoS2 target voltage of 4.7GPa. The highest critical load value was obtained as 26N at the highest MoS2 target voltage.

Abstract: Funding Acknowledgements Type of funding sources: None. Background Patients with heart failure with reduced ejection fraction (HFrEF) who received implantable cardiac defibrillator (ICD) still remain at high risk due to pump failure and comorbid conditions. C-reactive protein to albumin ratio (CAR) may be of value for identifying those with high risk for mortality despite ICD implantation. Methods Those who were implanted ICD for HFrEF in our institution between 2009 and 2019 were included. CAR was calculated as ratio of C-reactive protein (CRP) to serum albumin concentration. Patients were grouped into tertiles in accordance to CAR at the time of implantation. After follow up of 48 ± 35 months, survival times of tertiles were compared by using Kaplan-Meier survival method. Results Thousand and eleven patients constituted study population. Ischemic cardiomyopathy was primary diagnosis in 92.3%. Of those 14.5% had died after discharge. Patients in tertile 3 (T3) had higher risk of appropriate shock (19.3% vs 23.7% vs 38.0%) and mortality (4.2% vs 11.0% vs 28.5%) compared to those in other tertiles. Multivariable analysis revealed that when patients in T1 were considered as reference, both those in T2 and T3 had independently higher risk of appropriate shocks and mortality. These effects were consistent in the unadjusted and adjusted multivariable models. Conclusion Among patients with HFrEF and ICD, elevated CAR increased the risk of appropriate device shock and mortality at long term.

Abstract: Funding Acknowledgements Type of funding sources: None. Background The benefit of implantable cardiac defibrillator (ICD) in patients with heart failure and reduced ejection fraction (HFrEF) could be limited in a particular group of patients. Low prognostic nutritional index (PNI) indicates malnutrition and pro-inflammatory condition. We sought to investigate the value of PNI in predicting long-term mortality among HFrEF patients with ICD. Methods Electronic database was searched for identifying patients with HFrEF who were implanted ICD in our institution between 2009 and 2019. Demographic and clinical characteristics of included patients were recorded. PNI was calculated according to the formula: 10 x serum albumin (g/dL) + 0.005 x total lymphocyte count (per mm3). Patients were divided into the quartiles according to PNI values. Differences between the groups were analysed by the log-rank test. A forward Cox proportional regression model was used for multivariable analysis. Results One thousand and hundred patients were included to the study. The underlying heart failure etiology was ischemic and non-ischemic in 77.3% and 22.7% of patients respectively. Mortality rate in Q1 (5.1%) was considered as the reference. In the unadjusted model the mortality rate was 9.5% [hazard ratio (HR) 1.76, 95% confidence interval (95% CI) (0.92 – 3.38)] in Q2, 10.2% (HR 1.88, 95% CI 0.99 – 3.58) in Q3 and 39.6% (HR 8.12, 95% CI 4.65 – 14.17) in Q4. The same trend was consistent in the age- and sex-adjusted, comorbidities-adjusted and covariates-adjusted models. Conclusion Among patients who were implanted ICD secondary to HFrEF, lower PNI value predicted all-cause mortality during long-term follow up. This is the first study demonstrating the value of PNI in this population.

Abstract: Funding Acknowledgements Type of funding sources: None. Background Implantable cardiac defibrillators (ICD) are recommended in heart failure with reduced ejection fraction (HFrEF) patients to reduce arrhythmic deaths. The only contraindication for not implanting ICD is life expectancy of less than 1 year. We aimed to identify risk factors associated with mortality within 1 year following the device implantation. Methods Data from our hospital’s electronic database system was extracted for patients who were implanted ICD secondary to HFrEF between 2009 and 2019. Those who died within 1 year following the device implantation were analyzed in the present paper. Multiple Cox regression analysis using the backward logistical regression method was applied to determine the best predictors that affect 1-year mortality Results Overall 1107 patients were included in the present analysis. ICD was implanted in 77.2% and 22.8% for ischemic and non-ischemic HFrEF respectively. Mortality rate at 1-year following the device implantation was 4.7%. In multivariate analysis age [Hazard ratio (HR), 1.04; Confidence 95% Intervals (CI), 1.02 – 1.06; P = 0.001], atrial fibrillation (AF) (HR, 4.12; 95% CI, 2.34 – 7.24, P 2 symptoms (HR, 5.33; 95% CI, 2.92 – 9.73, P Conclusion In patients with HFrEF and implanted ICD, older age, presence of AF and NYHA class > II symptoms, elevated BUN and reduced albumin levels predicted 1-year mortality.

Abstract: Funding Acknowledgements Type of funding sources: None. Background Implantable cardiac defibrillators (ICD’s) are recommended in patients with heart failure with reduced ejection fraction (HFrEF) of nonischemic etiology. Determining patients who are at high risk despite ICD implantation is of clinical value. Methods Between 2009-2019 patients who were implanted ICD due to nonischemic HFrEF were included to the present analysis. Baseline characteristics, laboratory parameters and echocardiographic findings were obtained from the electronic database. The primary outcome was all-cause mortality. Appropriate and inappropriate device therapies were also extracted from the database and was confirmed with patients’ reports. Predictors for long term all-cause mortality was determined by using Cox regression analysis. Results Overall, 1199 patients were screened and 238 were eligible for the analysis. ICD’s were implanted for primary and secondary prevention in 68 (28.6%) and 170 (71.4%) of patients respectively. Multivariate analysis revealed that increased pro-BNP [Hazard ratio (HR): 1.001, 95% Confidence interval (CI): 1.000 – 1.001, p = 0.024] and reduced left ventricle ejection fraction (HR: 0.950, 95% CI: 0.907 – 0.994, p: 0.026) predicted all-cause mortality during long term follow up. Pro-BNP > 425 pg/ml has sensitivity and specificity of 74% for each in predicting all-cause mortality. Conclusion Among patients who were implanted ICD for HFrEF of nonischemic etiology, higher pro-BNP prior to the implantation and lower LVEF predicted all-cause mortality during long term follow up.
