Abstract
Antibody engineering can tailor the design and activities of therapeutic antibodies for better efficiency or other advantageous clinical properties. Here we report the development of ISB 1442, a fully human bispecific antibody designed to re-establish synthetic immunity in CD38+ hematological malignancies. ISB 1442 consists of two anti-CD38 arms targeting two distinct epitopes that preferentially drive binding to tumor cells and enable avidity-induced blocking of proximal CD47 receptors on the same cell while preventing on-target off-tumor binding on healthy cells. The Fc portion of ISB 1442 is engineered to enhance complement dependent cytotoxicity, antibody dependent cell cytotoxicity and antibody dependent cell phagocytosis. ISB 1442 thus represents a CD47-BsAb combining biparatopic targeting of a tumor associated antigen with engineered enhancement of antibody effector function to overcome potential resistance mechanisms that hamper treatment of myeloma with monospecific anti-CD38 antibodies. ISB 1442 is currently in a Phase I clinical trial in relapsed refractory multiple myeloma.

Abstract
BACKGROUND This single-center observational study aimed to compare the echocardiographic and clinical features in patients diagnosed with migraine and embolic stroke of undetermined source (ESUS) who presented with a known patent foramen ovale (PFO). METHODS Two-dimensional and color Doppler images were obtained using various transthoracic echocardiography views for both migraine and ESUS patients. Suspected PFO cases underwent further assessment through contrast echocardiography and transesophageal echocardiography (TEE). High-risk PFO characteristics were evaluated using TEE, and the Risk of Paradoxical Embolism (RoPe) score was calculated. RESULTS The study included 310 participants (age range: 18-60, 73.2% female), with 43.5% diagnosed with migraine and 56.5% with ESUS. Common comorbidities included diabetes (26.1%). High-velocity shunting through the interatrial septum was observed in 35.5% of patients. ESUS patients were older, with higher rates of diabetes and hypertension, while active smoking was more prevalent among migraine patients. Basic echocardiographic parameters were mostly similar, except for elevated pulmonary artery systolic pressure in ESUS. ESUS patients exhibited a greater occurrence of large microbubble passage through the interatrial septum and longer PFO lengths compared to migraine patients. However, the RoPe and High-risk PFO scores were similar between the groups. CONCLUSIONS ESUS patients, characterized by older age and higher rates of diabetes and hypertension, demonstrated increased pulmonary artery pressure, more significant microbubble crossings, and longer PFO lengths. Conversely, migraine patients had a higher prevalence of active smoking. Despite differing clinical profiles, the risk scores for PFO-related embolic events were comparable between the groups. These findings underscore potential distinctions between ESUS and migraine patients with PFO and their implications for management strategies.

Abstract
This study evaluated the effects of various types of feeding on fattening period and performance of Linda geese. Feeding patterns consisted of concentrate feed-based intensive and pasture feed-based semi-intensive. A total of 150 goslings aged three days were divided into two groups, each consisting of three replications. All groups were given rations containing 23% crude protein and 3100 kcal/kg ME in weeks 0–6, and rations containing 20% crude protein 3100 kcal/kg ME between weeks 7 and 17. After the seventh week, the feed for the semi-intensive group was diluted with 20% barley and from the tenth week, this group started to graze on pasture. Live weight gain of the two groups was similar, although geese kept indoors consumed more concentrate. Feed protein digestion of geese was similar in the two feeding types. Digestion-related visceral weight in the pasture-supplemented group increased, whereas carcass weight decreased. Growth curves were used to estimate the age of Linda geese to the end of the fattening period. The average slaughter age was the fourth and fifth months, as indicated by Von Bertalanffy, Logistic, and Gompertz growth models, which used the data from the third week. Concentrate feeding enabled Linda geese to reach earlier higher slaughter weight, although it was not considered economical. Although averages of bodyweight gain over the trial appeared slightly better in the concentrate-based intensive group, the results revealed that concentrate feed supplement and pasture may be the best and most economical form of feeding for Linda geese.

Abstract
Coronary artery fistulas are rare anomalies that often become symptomatic with age. They are typically diagnosed incidentally during coronary angiography. The chief nonsurgical treatment is transcatheter coil embolization. We evaluated the outcomes of this procedure in 17 symptomatic patients who had 22 fistulas in total. The 9 men and 8 women (mean age, 52 ± 16.5 yr; range, 27-74 yr) presented at 4 Turkish hospitals from October 2008 through March 2015. Three patients had multiple fistulas. Twelve fistulas originated from the right coronary artery and 10 from the left coronary artery, draining into the pulmonary artery in 18 instances. We evaluated results postprocedurally and after 2 to 5 months, defining angiographic success as a flow better than Thrombolysis in Myocardial Infarction grade 2 in the treated artery. Twenty-one of the 22 procedures immediately produced the targeted flow. We observed 2 minor and no major complications. On follow-up, 3 symptomatic patients underwent successful repeat treatment of one fistula each. We found that transcatheter coil embolization afforded good success rates with few complications in closing coronary artery fistulas. We share our experience to add to the data on treating patients with coronary artery fistulas, and to raise awareness among clinicians.

Abstract
Daily exposure to ultraviolet (UV) light induces inflammation and tumorigenesis in the skin. Silibinin and ellagic acid are natural products that exhibit anti-inflammatory and anti-tumorigenic properties. Insulin receptor substrate protein 1 (IRS1) is important for skin homeostasis and physiology, but its activity following UV radiation remains unclear. We investigated the effects of ellagic acid and silibinin on IRS1 expression in ultraviolet A (UVA) and ultraviolet B (UVB) irradiated rat skin. Forty-two female Wistar rats were divided randomly into six groups of seven animals. The dorsal skin of rats was exposed to UVA + UVB, then treated with ellagic acid and silibinin by gavage. IRS1 expression in skin tissues was determined by western blot analysis. IRS1 expression increased significantly following treatment with ellagic acid and silibinin in UVA + UVB irradiated skin compared to the UVA + UVB only group. After UVA + UVB treatment, ellagic acid effected greater induction of IRS1 expression than silibinin. Our findings suggest that the photoprotective roles of ellagic acid and silibinin may be due to induction of IRS1 expression in UVA + UVB treated rat skin.

Abstract
Abstract
Background
Arrhythmogenic cardiomyopathy (AC) is an important cause of ventricular arrhythmias in children and young adults. AC is associated with mutation of desmosomal proteins, however, cardiac disease penetrance is incomplete and the clinical course varies widely without recognizable exogenous or epi/genetic co-factors. Importantly, DSP mutation carriers may also display entirely non-cardiac e.g. dermatological phenotypes.
Methods and results
In two brothers with recurrent fulminant myocarditis, mutation screening of 218 cardiomyopathy-related genes identified a truncating mutation Arg1458* of desmoplakin (DSP). DSP immunhistology unexpectedly revealed complete loss (“knockout”) of DSP protein in endomyocardial biopsies (EMBs), but none of the histological anomalies of AC. Criteria for histological diagnosis of myocarditis were not either fulfilled, and cardiac MRI revealed no features associated with AC. Screening for infections was negative, there was no substance abuse, medication or vaccination. Possible disease triggers were competitive sport events. Myosin and troponin I autoantibodies were detected at titers up to 1:320.
We used allele-specific RT-PCR to distinguish if the patients' allele classified as “normal” was actually defective due to promotor mutation or epigenetic silencing. RT-PCRs were done on EMBs and peripheral blood mononuclear cells (PBMCs). In a cohort of dilated cardiomyopathy (DCM) patients we were able to detect DSP transcripts in both, PBMC and left-ventricular heart tissue. RNA sequencing of human PBMC subpopulations suggested that DSP transcription may be restricted to certain immune cell subtypes. RT-PCRs revealed that both Arg1458* carriers have a functional second DSP allele, indicating that their “DSP knockout” occurs at the protein level and may be due to protein instability and degradation within desmosomes.
We screened additional existing cohorts for such variants and identified stopgain variant Gln307Ter in a 37-yrs-old woman with ARVC. This patient's sister died from heart failure at the age of 39. In a 59-yrs-old female LVNC patient, stopgain variant Y1391X was identified. Here, family history was unclear, her brother probably died from coronary artery disease. In a 71-yrs-old female DCM patient with no family history, stopgain variant Tyr1512Ter was identified.
Conclusions
The described patients with DSP truncations strongly suggest the existence of additional genetic or exogenous modifiers driving pathogenesis either way. DSP defects may cause recurrent myocarditis, and mutation screening is advisable to enable early detection of high-risk patients with similar phenotypes. Our finding of complete myocardial DSP protein loss emphasizes that DNA sequencing may miss critical molecular disturbances. It is indispensable to also analyze transcriptome and protein level in the tissue actually affected in a patient in order to recognize his/her individual pathogenesis.

Abstract
Renal infiltration in children with acute leukemia has been reported previously; however, it has rarely been described in association with atypical hemolytic uremic syndrome (aHUS). We present a case of 9-year-old boy who developed life-threatening aHUS in the 1st week of Burkitt leukemia/lymphoma diagnosis with renal infiltration. Complete resolution of aHUS was achieved after therapeutic plasma exchange. This is an uncommon complication of Burkitt leukemia/lymphoma in a pediatric case.

Abstract
BACKGROUND The association between epicardial fat thickness (EFT) and positive exercise test results for the diagnosis of coronary artery diseases (CAD) has yet to be evaluated. This study assessed the predictive value of EFT for CAD on the angiographs of patients with positive exercise tests. METHODS A total of 91 subjects were chosen consecutively from stable angina pectoris patients who were referred for coronary angiography due to a positive exercise test result. The EFT measures were obtained by echocardiographic parasternal long-axis views on the free wall of the right ventricle at end-systole of three cardiac cycles. Gensini scores were calculated by a conventional coronary angiography technique using a calculation method previously defined. RESULTS Receiver operator characteristic (ROC) curve analysis revealed a 0.65 cm (95% confidence interval: 0.628, 0.832, p < 0.001) area under the curve with 74.3% sensitivity and 62.3% specificity at the cut-off value of EFT for the prediction of critical coronary artery stenosis. Following ROC curve analysis, two groups were defined according to EFT cut-off value (groups 1 and 2). The severe coronary stenosis ratio was significantly higher in group 2 compared to group 1 (31.9 % vs. 11%, p < 0.001) and Gensini scores were significantly higher in group 2 (6.3 ± 13.3 vs. 16.5 ± 17.9; p < 0.001). There was no significant correlation between Gensini scores and EFT in group 1 (r = 0.093, p = 0.549), but there was a strong significant correlation in group 2 (r = 0.730, p < 0.001). Linear multivariate regression analysis revealed that EFT (> 0.65 cm) was the only independent risk factor for critical coronary artery stenosis (β = 0.451, p < 0.001). CONCLUSIONS EFT was significantly correlated with the severity and prevalence of coronary artery disease in positive exercise test patients.

Abstract
BACKGROUND The metabolic syndrome (MetS) is characterized by a cluster of metabolic factors, including insulin resistance and type-2 diabetes, abdominal obesity, dyslipidemia, hypertension and microalbuminuria. Impaired glucocorticoid receptor (GR) activity also plays an important role in the etiology of MetS. The objective of our study is to evaluate the effects of GR gene polymorphisms (BclI, N363S, TthIII1 and ER22/23EK) in Turkish patients with MetS. MATERIALS AND METHODS Seventy subjects with MetS and 185 healthy controls were enrolled in the study. PCR-RFLP analysis was used for genotyping. Results for each polymorphism have been verified by allele-specific oligonucleotide analysis. RESULTS BclI GG genotype was significantly associated with an increased risk of MetS (p = 0.02). Also, only in women, the G allele carriers were significantly associated with higher C-peptide. T allele carriers of TthIII1 polymorphism were significantly associated with higher C-peptide, triglyceride, insulin and C-reactive protein (CRP, p value 0.048, 0.022, 0.005 and 0.022, respectively), and lower fasting blood glucose (FBG, p = 0.02). The combined carriers of BclI polymorphism G allele and TthIII1 polymorphism T allele were significantly associated with higher diastolic blood pressure in all patients, and lower FBG and postprandial blood glucose in only men. All the ER22/23EK polymorphisms coexisted with polymorphic variant of TthIII1 (p = 0.0058). CONCLUSION The presence of homozygote polymorphic variant of BclI might be good predictive markers for the disease susceptibility. The BclI and the TthIII1 polymorphism are associated with sex-specific clinical parameters. Our findings also suggest that the combination of BclI and TthIII1 polymorphisms may play a protective role in blood glucose.

Abstract
Objective: Heart rate recovery (HHR) after exercise is a function of vagal reactivation. This study aimed to evaluate HHR index in patients with erectile dysfunction. Methods: Men over the age of 18 years who were diagnosed with erectile dysfunction were included in the study. Ninety patients with erectile dysfunction (mean age=56.1±8.3 years) and 50 healthy subjects as controls (mean age=53.1±10.4 years) were compared. The erectile status of patients was evaluated using the sexual health inventory for men questionnaire. Basal electrocardiography, echocardiography, and treadmill exercise testing were performed in all patients and controls. The HHR index was defined as the reduction in heart rate from the rate at peak exercise to the rate at the first minute (HRR1), second minute (HRR2), third minute (HRR3), and fifth minute (HRR5) after terminating exercise stress testing. An independent sample t-test, Pearson correlation coefficient test, linear multivariate regression analysis, and receiver operating characteristic curve analysis were used for statistical assessment. Results: All HHR indices were found to be significantly decreased in patients with erectile dysfunction (p<0.001). Effort capacity was markedly lower (9.1±2.3 vs. 10.4±2.3 METs, p=0.002) among patients with erectile dysfunction. HRR1 and HRR3 were found to be an independent risk factor for erectile dysfunction (Beta=0.462, p<0.001; Beta=0.403, p<0.001; respectively) in linear regression analysis. Conclusion: Decreased HHR index may be considered as one of the independent predictors of impaired autonomic function in patients with erectile dysfunction.

Abstract
OBJECTIVES The aim was to study transradial approach (TRA) and transfemoral approach (TFA) in terms of feasibility, effectiveness, usefulness, and procedure characteristics in patients having ST-segment elevation myocardial infarction (STEMI) and undergoing primary percutaneous coronary intervention (PCI). Along with the said aim, major adverse cardiovascular events (MACE) at follow-up were also compared. METHODS The present study was conducted on 344 consecutive patients having ST-segment elevation myocardial infarction and qualifying for PCI. Patients were classified into two groups according to radial and femoral approaches. Patients were followed-up for MACE. RESULTS PCI was found to be successful in all patients. In TRA group the time between the end of the intervention to removal of the sheath, and duration of mobilization and hospitalization were significantly shorter when compared to TFA group (12 ± 2 minutes vs. 240 ± 12 minutes; P = 0.001, 13 ± 2 hours vs. 22 ± 2 hours; P = 0.001, and 96 ± 45 hours vs. 125 ± 55 hours; P = 0.001, respectively). In TRA group, two patients had hematomas greater than 2 cm while fourteen patients in TFA group had hematomas greater than 5 cm (1% vs. 8%; P = 0.002). TRA group had lower in-hospital MACE rates (5% vs. 11%; P = 0.036). The long terms MACE rates of the groups were similar (23% vs. 22%; P = 0.888). CONCLUSIONS In patients with STEMI, PCI via TRA had the same effectiveness as TFA. Moreover, Time to ambulation and rates of bleeding complications were reduced by TRA, which allowed early rehabilitation. TRA reduced the incidence of in-hospital MACEs.

Abstract
BACKGROUND The aim of the present study was to perform a preliminary evaluation of the potential association between platelet distribution width (PDW) and frequency of major adverse cardiovascular events (MACEs) development in an observational study of acute coronary syndrome (ACS) patients. METHODS A total of 679 consecutive patients with ACS (498 (73.3%) males; mean age was 63.31±11.2 years; study population composed of 320 patients with acute myocardial infarction and 359 patients with unstable angina pectoris) subjected to primary percutaneous coronary intervention with transradial approach (TRA) were retrospectively enrolled to the study. Tertiles were formed based on PDW levels. The associations between PDW and in-hospital and long-term MACEs were analysed. RESULTS The frequencies of in-hospital instent thrombosis (P=0.05), long-term instent restenosis (P=0.005) and long-term total MACEs (P=0.008) were higher in tertiles having a high PDW value. In multivariate analyses, PDW was an independent predictor of in-hospital and long-term MACEs (odds ratio 1.081, 95% confidence interval 1.003-1.165; p=0.042). The projected Kaplan-Meier incidence of a MACEs in the PDW tertiles groups were 12.8%, 12.1%, and 21.6% at 40 months (respectively, p=0.003). CONCLUSIONS The pre-procedural PDW may be an independent predictor of both in-hospital and long-term adverse outcomes in patients with ACS.

Abstract
OBJECTIVES The aim of this study was to use echocardiographic techniques to determine the possible cardiotoxic effects of low molecular weight tyrosine-kinase inhibitors (TKI) in patients receiving the therapy for the first time. STUDY DESIGN Thirty patients (17 females; 13 males; mean age 49±16; range 22 to 76 years) who met the exclusion criteria and were diagnosed as having malignancy were enrolled. All patients underwent conventional echocardiography and tissue Doppler imaging (TDI) prior to the treatment. The conventional echocardiogram was repeated 2 months later as the patients were concurrently receiving therapy. Myocardial Performance Index was obtained by conventional echocardiography and by TDI techniques to evaluate left ventricular systolic and diastolic function. RESULTS Statistically significant increase occurred in mean left ventricle (LV) end-systolic volume. However, there was significant decrease in both mean LV ejection fraction and LV stroke volume values (64±3, 62±4, p=0.000 and 67±13, 61±13, p=0.000, respectively). Anterior wall Em/Am ratio measured by using the TDI technique was significantly decreased at the end of two months (0.99±0.49, 0.90±0.41, p=0.03). In addition, decreases were determined in Sm values obtained from all of four LV walls and also in mean Sm value, but this decrease was significant only for the lateral wall Sm measurement (12.8±2.9, 11.6±2.3, p=0.004). CONCLUSION Tyrosine-kinase inhibitors therapy can be administered safely to patients without predisposing factors for cardiotoxicity in short treatment intervals, and low molecular TKIs may cause subtle or clinically significant cardiotoxicity following the treatment period even in patients without predisposing factors for cardiotoxicity, so clinicians should consider this possibility.

Abstract
OBJECTIVE To evaluate thoracic periaortic adipose tissue (TAT) volume in patients with subclinical hypothyroidism (SH) in comparison with controls and in relation to cardiovascular risk factors. METHODS The study population consisted of 28 newly diagnosed SH patients (mean (s.d.) age: 37.3 (±11.4) years, 85.7% were females) and 37 healthy volunteers (mean (s.d.) age: 35.3 (±10.7) years, 81.5% were females). Comparisons between patient and control groups used demographic characteristics, anthropometrics, and laboratory findings. All participants underwent thoracic radiographic assessment in the supine position, using an eight-slice multidetector computed tomography scanner and TAT volume was measured. RESULTS The TAT volume was determined to be 27.2 (±12.7) cm(3) in the SH group and 16.3 (±8.1) cm(3) in the control group, and the difference was statistically significant (P<0.001). In addition, TSH levels were significantly higher in the patient group compared with the control group (P<0.001). A significant correlation was also found between TSH levels and TAT volume (r=0.572; P<0.001). In SH patients, no significant difference was noted in TAT levels with respect to sex (P=0.383) or concomitant smoking status (P=0.426). CONCLUSIONS Our findings indicate that SH patients have significantly higher TAT values than controls and that increased TAT levels correlate with increased TSH levels.

Abstract
Background: Acute pulmonary embolism (PE) is a life-threatening and a relatively common cardiovascular pathology. Although the pathogenesis of PE is well defined, there is no ideal diagnostic biochemical marker. Previous studies showed an increased ischemia modified albumin (IMA) levels in acute PE; however, the relationship between IMA and right ventricular (RV) dysfunction has not been examined. The aim of this study was to evaluate the diagnostic value of IMA and the relationship with RV dysfunction in acute PE. MATERIALS AND METHODS: A total of 145 patients (70 females) with suspected acute PE was enrolled to the study. Eighty-nine patients were diagnosed with acute PE via computed tomographic pulmonary angiography. Sixty-five patients with similar demographic and clinical characteristics were assigned to the control group. All patients were evaluated for RV dysfunction using transthoracic echocardiography. Results: Serum IMA levels were significantly increased in acute PE compared with control group (0.41 ± 0.06 vs. 0.34 ± 0.11, P = 0.001). There was no relationship between serum IMA levels and RV dysfunction. IMA levels were positively correlated with shock index and heart rate. Receiver operating curve analysis demonstrated that serum IMA levels higher than 0.4 put the diagnosis at sensitivity of 53.85% and at specificity of 85.96%. Conclusions: Although IMA levels are increased in patients with acute PE, it failed to predict RV dysfunction.

Abstract
Infection is one of the most devastating outcomes of cardiovascular implantable electronic device (CIED) implantation and is related to significant morbidity and mortality. In our country, there is no evaluation about CIED infection. Therefore, our aim was to investigate clinical characteristics and outcome of patients who had infection related to CIED implantation or replacement. The study included 144 consecutive patients with CIED infection treated at 11 major hospitals in Turkey from 2005 to 2014 retrospectively. We analyzed the medical files of all patients hospitalized with the diagnosis of CIED infection. Inclusion criteria were definite infection related to CIED implantation, replacement, or revision. Generator pocket infection, with or without bacteremia, was the most common clinical presentation, followed by CIED-related endocarditis. Coagulase-negative staphylococci and Staphylococcus aureus were the leading causative agents of CIED infection. Multivariate analysis showed that infective endocarditis and ejection fraction were the strongest predictors of in-hospital mortality.

Abstract
Background We investigated the relationship between peripheral neuropathy and parameters of arterial stiffness and carotid intima media thickness (CIMT) in patients with type 2 diabetes mellitus (T2DM). Material/Methods The study included 161 patients (80 females and 81 males), 69 of whom had peripheral neuropathy. All patients underwent 24-h blood pressure monitoring, and arterial stiffness parameters were measured. The CIMT was measured using B-mode ultrasonography and patients also underwent transthoracic echocardiographic examination. Results Patients with peripheral neuropathy, compared with those without it, were older (54.68±8.35 years vs. 51.04±7.89 years; p=0.005) and had T2DM for longer periods (60 vs. 36 months; p=0.004). Glycated hemoglobin (HbA1c) values (8.55±1.85 mg/dL vs. 7.30±1.51 mg/dL; p<0.001), pulse wave velocity (PWV) (7.74±1.14 m/s vs. 7.15±1.10 m/s; p=0.001), CIMT (anterior 0.74±0.15 mm vs. 0.67±0.13 mm; p=0.01), and left ventricular mass (LVM) index (98.68±26.28 g/m2vs. 89.71±19.70 g/m2; p=0.02) were all significantly increased in the group with peripheral neuropathy compared to the group without peripheral neuropathy. We determined that duration of diabetes, HbA1c, and LVM index were predictors of peripheral neuropathy. Conclusions A significant relationship was found between diabetic neuropathy and increased PWV, a parameter of arterial stiffness, as well as CIMT, a marker of systemic atherosclerosis. Diabetic peripheral neuropathy may be a determinant of subclinical atherosclerosis in T2DM.

Abstract
OBJECTIVE To evaluate thoracic periaortic adipose tissue (TAT) burden in patients with type 2 diabetes mellitus (DM) in comparison with controls and in relation to cardiovascular risk factors. METHODS A total of 93 patients with type 2 DM (mean (standard deviation; SD) age: 56.7 (11.2) years, 71.0 % were men) and 85 nondiabetic control subjects (mean (SD) age: 54.6 (10.9) years, 58.8 % were men) who were admitted to Mevlana University hospital between January 2011 and June 2013 and underwent multidetector computed tomography for any reason were included in this retrospective cohort study. Patient and control groups were compared in terms of demographic characteristics, anthropometrics, and laboratory findings. TAT volume was evaluated in both groups, while correlates of TAT were determined via linear regression analysis among patients. RESULTS In patients with type 2 DM, TAT volume (40.1 (23.9) versus 16.9 (7.7) cm(3), p < 0.001), fasting blood glucose (p < 0.001), total cholesterol (p < 0.001), triglyceride (p = 0.017), and low-density lipoprotein (LDL) cholesterol (p = 0.034) levels were significantly higher compared with the control group. Strong positive correlation of TAT was noted with body mass index (r = 0.339, p = 0.001) and serum levels for fasting blood glucose (r = 0.343, p < 0.001), hemoglobin A1c (HbA1c; r = 0.615, p < 0.001), total cholesterol (r = 0.269, p = 0.009), and LDL cholesterol (r = 0.258, p = 0.013). In stepwise regression analysis, Hba1c emerged as a significant predictor of TAT (b = 0.610, p < 0.001), contributing to 19 % of its variability. CONCLUSION In conclusion, our findings indicate significantly higher values for TAT in diabetics than controls, being associated positively with body weight, poor glycemic control, and dyslipidemia and strongly predicted by HbA1c levels in diabetic patients, while not differing with respect to gender, smoking status, and concomitant hypertension.

Abstract
We investigated the relationship between epicardial fat volume (EFV) measured by multislice computed tomography (MDCT) and long-term major adverse cardiac events (MACEs). Consecutive patients (n = 564) were enrolled in this retrospective study. Patients were divided into tertiles according to EFV. Patients were followed up for an average of 18 months. Patients in each tertile were similar in terms of gender and risk factors. Patients with greater EFV in the third group were more likely to be overweight ( P = .001) and older ( P = .001). High-density lipoprotein cholesterol levels were relatively lower in the third tertile (45 ± 9, 45 ± 11, and 43 ± 9 mg/dL, respectively; P = .018). The third group had a significantly higher rate of myocardial infarction (0.6%, 1.1%, and 3.7%, respectively; P = .043). The incidence of MACEs during the follow-up period was highest in the third group 15.9% (4.1%, 7.7%, and 15.9%, respectively; P = .001). Epicardial fat volume measured by MDCT was associated with increased long-term cardiovascular risk.

Abstract
Negative pressure pulmonary edema (NPPE) is defined as fluid transudation into the pulmonary interstitium which occurs as a result of elevated negative intrathoracic pressure caused by the upper respiratory tract obstruction and strong inspiratory effort. NPPE is usually seen during emergence from general anesthesia in the early post-operative period especially after upper respiratory tract surgery. We present a case of a 37-year-old male patient who underwent septoplasty operation and developed NPPE which could not diagnosed and progressed to acute subendocardial myocardial infarction.

Abstract
BACKGROUND Endothelial dysfunction plays a major role in erectile dysfunction (ED). Uric acid (UA) is a marker of endothelial dysfunction. We hypothesized that increased UA levels may be associated with ED and aimed to investigate whether there is a relationship between, UA and ED in hypertensive patients. METHODS A total of 200 hypertensive patients who have a normal treadmill exercise test were divided into two groups based on the Sexual Health Inventory for Men (SHIM) test (< 21 defined as ED n = 110, and ≥ 21 defined as normal erectile function n = 90). The differences between the ED and normal erectile function groups were compared and determinants of ED were analyzed. MAIN RESULTS The prevalence of ED was found to be 55.0%. Office blood pressure level was comparable between groups. UA levels were significantly increased in the ED group (6.20 ± 1.56 vs 5.44 ± 1.32, p = 0.01). In a regression model, age [odds ratio (95% confidence interval): 1.08 (1.04-1.14), p = 0.001], smoking [odds ratio: 2.33 (1.04-5.20), p = 0.04] and UA [odds ratio: 1.76 (1.28-2.41), p = 0.04] were independent determinants of ED. An UA level of > 5.2 mg/dl had 76.2% sensitivity, 43.7% specificity, 62.9% positive and 59.4% negative predictive value for determining ED. CONCLUSION UA is an independent determinant of ED irrespective of blood pressure control and questioning erectile function for hypertensive patients with increased UA levels may be recommended.

Abstract
BACKGROUND Ceruloplasmin (Cp) is a serum protein that belongs to the family of α2-globulins and it is increased in patients with after acute myocardial infarction complicated with heart failure. Aim of the study was to investigate levels of serum Cp in patients with acute decompensated heart failure. MATERIALS AND METHODS The present cross-sectional observational study consists of three groups: Fifty patients with decompensated heart failure (Group 1) and same 50 patients after compensation (Group 2); 50 control patients group with comparable age and sex without heart failure (Group 3). Demographic, echocardiographic and biochemical data of patients were collected. Serum Cp level was determined spectrophotometrically. RESULTS Serum ceruloplasmin was significantly increased in Groups 1 (820.8 ± 78.5 IU/dL) and 2 (873.5 ± 121.0 IU/dL) compared, to Group 3 (640.6 ± 132.4 IU/dL) (p<0.001). In the sub-group analysis, this difference was due to the difference between Groups 3, Group 1 and 2 (both p=0.0001) whereas no significant difference was present between Group I and Group 2 (p>0.063). A positive correlation was found between Cp and female sex, heart rate, systolic and diastolic blood pressure, acetylsalisilic acid and diuretic use, left ventricular systolic and diastolic diameter, mitral regurgitation, and negative correlation was found between Cp and ejection fraction (p<0.05 for all) whereas none of the parameters were independently associated with serum Cp level (p>0.05). CONCLUSIONS Findings of the present study suggest that serum Cp level is increased in both decompensated and compensated HF compared to controls. Further large scale studies are needed to elucidate the pathophysiological mechanisms of increased Cp in HF.
