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
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
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
OBJECTIVE In this study, the associations between pulmonary artery stiffness (PAS) and aortic stiffness, left ventricular diastolic parameters, and left ventricular mass (LVM) index in moderate to severe obstructive sleep apnea syndrome (OSAS) patients without coexisting disorders were investigated. METHODS A total of 66 non-diabetic, non-hypertensive, and non-smoking volunteers were enrolled. Participants were categorized by apnea-hypopnea index (AHI; event/hour). The control group was defined as no OSAS: AHI<5 (n=35), and OSAS group had moderate to severe OSAS: AHI>15 (n=31).Echocardiographic and biochemical tests, including measurement of C-reactive protein (CRP), were performed. PAS (kHz/s) was calculated by dividing the maximal frequency shift of the pulmonary flow by the acceleration time. RESULTS PAS (kHz/s), obtained by echocardiography, was statistically significantly higher in the OSAS group than the control group (28±5 vs 18±4, p<0.001), and was positively correlated with AHI, CRP, aortic stiffness index, E/E', and LVM index (p=0.034, p=0.039, p<0.001, p=0.040, and p<0.001, respectively), and negatively correlated with aortic strain (AS), aortic distensibility (AD), E/A, E'/A', and E' (p<0.001). Regression analyses indicated that CRP and PAS are independent predictors of aortic stiffness (p<0.05). E/A and LVM index were independent predictors of PAS (p=0.002 and p=0.001, respectively). CONCLUSION Increased PAS is associated with aortic stiffness, left ventricular diastolic function, and increased LVM index. PAS may be a more effective indicator of aortic stiffness in OSAS patients than CRP.

Abstract
OBJECTIVE To examine the effects of Ramadan fasting on body composition, arterial stiffness and resting heart rate. METHODS This prospective study was conducted at the Department of Cardiology, Harran University, Sanliurfa, Turkey, during Ramadan 2015, and comprised overweight and obese males. Body composition, arterial stiffness and echocardiography were assessed before and after Ramadan. Body composition was assessed by bioelectrical impedance analysis using segmental body composition analyser. Arterial stiffness and haemodynamic parameters were also measured. SPSS 20 was used for data analysis. RESULTS Of the 100 subjects enrolled, 70(70%) were included. The overall mean age was 37±7 years. No significant changes were observed in blood pressures, resting heart rate, aortic pulse wave velocity, aortic augmentation index-75, aortic pulse pressure, brachial pulse pressure, basal metabolic rate, total body water, fat-free mass, and echocardiographic parameters (p>0.05 each). Although aortic pulse wave velocity (m/s) and augmentation index-75 (%) decreased after fasting period compared to that of before Ramadan, these reductions did not reach statistically significant levels (8.6±1.8 vs. 8.9±1.9, and 13.6±6.6 vs. 14.7±9.3, respectively; p>0.05 each). Body mass index, waist-hip ratio, body water rate, percentage of body fat mass, body fat mass, and visceral fat mass percentage were significantly reduced (p<0.05 each) after Ramadan. CONCLUSIONS Ramadan fasting had beneficial effects on body composition, but did not have any significant effect on arterial stiffness and resting heart rate.

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
Background: Obesity and overweight are risk factors for atherosclerosis. Red blood cell distribution width (RDW) is associated with subclinical cardiac diseases. The aim of this study was to investigate the association between RDW and aortic stiffness in overweight or obese subjects. Methods: A total of 101 overweight or obese subjects without overt cardiovascular disorders, and 48 healthy controls were enrolled. RDW, aortic pulse-wave velocity (PWV) and augmentation index 75 (Aix75) were evaluated. The case subjects were divided into two sub-groups according to PWV values; ≥ 10 m/s in group I, and < 10 m/s in group II. Bivariate correlation and multiple regression analyses (stepwise) were performed. Results RDW and PWV were considerably increased in the case groups compared with the controls. RDW was significantly increased in group I compared with group II and the controls [median 12.0 m/s, interquartile range (IQR): 10.5–17.5; median 11.7 m/s, IQR: 10.2–14.2, and median 11.4 m/s, IQR: 9.6–15.5, p < 0.05, respectively]. Resting heart rate and age were higher in group I than group II (81 ± 11 vs 74 ± 12 beats/min and 41 ± 120 vs 36 ± 9 years, respectively, p < 0.05). Regression analyses revealed that while log-RDW, age and resting heart rate were independent predictors for aortic PWV, log-RDW was the most important predictor in the final model. Conclusions: RDW, resting heart rate and age independently predicted arterial stiffness, and RDW may be useful to provide an early recognition of subclinical atherosclerosis in overweight and obese individuals.

Abstract
OBJECTIVES Although atrial fibrillation (AF) is one of the most common rhythm disorders observed in clinical practice, a multicenter epidemiological study has not been conducted in our country. This study aimed to assess our clinical approach to AF based upon the records of the first multicenter prospective Atrial Fibrillation in Turkey: Epidemiologic Registry (AFTER) study. STUDY DESIGN Taking into consideration the distribution of the population in our country, 2242 consecutive patients with at least one AF attack determined by electrocardiographic examination in 17 different tertiary health care centers were included in the study. Inpatients and patients that were admitted to emergency departments were excluded from the study. Epidemiological data of the patients and the treatment administered were assessed. RESULTS The mean age of the patients was determined as 66.8 ± 12.3 years with female patients representing 60% of the study population. While the most common AF type in the Turkish population was non-valvular AF (78%), persistent/permanent AF was determined in 81% of all patients. Hypertension (%67) was the most common co-morbidity in patients with AF. While a stroke or transient ischemic attack or history of systemic thromboembolism was detected in 15.3% of the patients, bleeding history was recorded in 11.2%. Also, 50% of the patients were on warfarin treatment and 53% were on aspirin treatment at the time of the study. The effective INR level was detected in 41.3% of the patients. The most frequent cause of not receiving anticoagulant therapy was physician neglect. CONCLUSION These results demonstrate the necessity for improved quality of physician care of patients with AF, especially with regards to antithrombotic therapy.

Abstract
OBJECTIVES Prolidase is an important factor in collagen metabolism, matrix remodelling and cell growth. Increased collagen turnover leading to increased ventricular stiffness plays an important role in the pathophysiology of left ventricular diastolic dysfunction (LVDD). This study aims to investigate whether serum prolidase activity is related to left ventricular diastolic function. METHODS We studied 144 participants, and divided them into four groups according to the phase of diastolic dysfunction (66 with normal function, 46 with impaired relaxation, 19 with pseudonormalization, and 13 with restrictive-like filling). Assessment of diastolic filling was carried out with the measurements of E wave, A wave, E-wave deceleration time, isovolumic relaxation time, lateral tissue Doppler E S, E and A wave. Serum prolidase activity was measured by spectrophotometrical methods. RESULTS Serum prolidase activity level was higher in patients with left ventricular diastolic dysfunction (LVDD) than without LVDD (P = 0.004). Also, prolidase activity values gradually increased from stage I through stage III in patients with LVDD. Multivariate analysis shows that LVDD is independently associated with age (β = 0.066, SE = 0.017, P = 0.006), hypertension (β = -1.252, SE = 0.354, P = 0.037) and prolidase activity (β = 0.021, SE= 0.088, P= 0.045). CONCLUSION Our data have shown that, in a selected group of patients, serum prolidase activity was positively and independently associated with the presence and severity of LVDD.

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
Oxidative stress (OS) is important in the pathogenesis of atherosclerosis. Paraoxonase-1 (PON1) is an enzyme found in the circulation associated with high-density lipoprotein (HDL). HDL-associated enzyme PON1 has an important role in the attenuation of atherogenic low-density lipoprotein (LDL) oxidation. The aim of this study was to determine PON1 and arylesterase (AREST) enzyme levels in relation to insulin resistance (IR) or obesity among children and adolescents. The study included healthy school children and adolescents. Blood was drawn for the determination of blood glucose, lipid, PON1 and AREST enzyme levels. Overall, we observed a positive correlation between PON1 enzyme activity and high-density lipoprotein cholesterol (HDL-C) levels (r = 0.189, P = 0.014). The correlation appeared to be more significant in boys (r = 0.271, P = 0.009). For subjects with IR and obesity, PON1 enzyme activity did not correlate with HDL-C levels (r = 0.038, P = 0.790), instead PON1 levels correlated negatively with BMI (r = -0.309 and P = 0.026). Multiple linear regression analysis was performed to find the predictors of log PON1 activity. HDL-C level was the strongest predictor of PON1 activity in the lean control group, while BMI appeared to be the strongest predictor in the subjects with obesity or IR. In conclusion, determinants of PON1 enzyme activity are variable in children and adolescents based on IR and obesity. Future studies will shed light on the underlying mechanisms and biomarkers of OS in children and may reveal possible targets for therapeutic intervention.

Abstract
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) syndromes is a rarely seen multisystem disorder with autosomal recessive inheritance due to thymidine phosphorylase gene mutation. It is characterized by progressive external ophthalmoplegia and/or pitosis, progressive gastrointestinal dismotility and abdominal pain, postprandial emesis, cachexia, demyelinating peripheral neuropathy, symmetrical and distal weakness especially in lower extremities and diffuse leucoencephalopathy in cranial magnetic resonance. Endocarditis is the infectious and inflammatory disease of the endothelial surface of the heart. MNGIE syndrome is a condition in which immune system is suppressed and infection risk increased. Herein we summarized a previously not reported endocarditis case in a patient with MNGIE syndrome who was under follow up for three years. In MNGIE syndrome of acute dyspnea, infective endocarditis should be kept in mind and prompt evaluation for surgical treatment should be done.

Abstract
We aimed to assess the impact of meteorological variables on coronary blood flow (CBF). Coronary blood flow was evaluated using the thrombolysis in myocardial infarction frame count (TFC). The association of CBF with meteorological parameters such as temperature, relative humidity, total solar radiation, atmospheric pressure, wind velocity, and total sunshine duration were investigated as well as demographic, clinical, and laboratory characteristics. Assessment of 1206 patients (median age = 53 years, 723 females) revealed the presence of slow coronary flow (SCF) in 196 patients. Daily maximum temperature [odds ratio = 0.951, 95% confidence interval = 0.916-0.986, P = .007] was the only independent predictor of the presence of SCF, whereas systolic blood pressure (β = -0.139, P = .026), hematocrit level (β = 0.128, P = .044), and daily maximum temperature (β = -1.479, P = .049) were independent predictors of log10 (mean TFC). Findings of the present study suggest a role of meteorological parameters in CBF regulation.

Abstract
Objective: To investigate mean platelet volume (MPV) levels in patients with coronary slow flow (CSF). Methods: 465 stable angina pectoris cases with angiographically normal coronary arteries were recruited [coronary slow flow group (n=76), control group (n=389)] in the observational retrospective cohort study. Clinical, biochemical and demographic variables including MPV were noted and coronary blood flow was assessed with TIMI frame count (TFC). Results: Gender, smoking, height, serum creatinine, uric acid levels, hemoglobin, waist/hip ratio, systolic blood pressure but not MPV were significantly different among groups. Independent predictors of CSF were height (p=.029) and serum uric acid level (p=.045). Gender, height, weight, hip circumference, systolic blood pressure, fasting blood glucose, serum urea, creatinine, uric acid levels, hemoglobin and platelet count were associated with mean TFC whereas independent predictors of mean TIMI frame count were height (p=.010) and serum uric acid level (p=.041). Conclusion: Height and serum uric acid level but not MPV were independent predictors of both CSF and mean TFC.

Abstract
[Purpose] The purpose of this study was to investigate the possible relationship between joint destruction and carotid intima-media thickness in patients with rheumatoid arthritis. [Subjects and Methods] Thirty-four RA patients and 31 healthy controls were enrolled in this study. The disease activity for 28 joints was recorded for each patient using the erythrocyte sedimentation rate (DAS28ESR), a visual analog scale (VAS0-10 cm), and a disability index, the health assessment questionnaire (HAQ). X-ray imagesof the patients were scored according to the modified Sharp/van der Heijde method, and the common carotid intimal medial thickness (CIMT) was automatically measured with software using high-resolution Doppler ultrasound. [Results] Contrary to our hypothesis, the modified total Sharp score (mTSS) and CIMT were not significantly associated. The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels of the RA patients and the right CIMT, left CIMT, and mean CIMT scores were significantly elevated. Positive correlation was detected between the mean CIMT score and age, CRP levels, LDL concentration and triglycerides (TG) level. In the regression model, where the mean CIMT was the independent variable and age, CRP, LDL, and TG were dependent variables, age was found to be an independent predictor of CIMT. [Conclusions] Patients suffering from RA require close monitoring for cardiovascular risks, and the comorbidity of age-related cardiovascular disease should not be overlooked.

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.

Abstract
OBJECTIVES We investigated the effects of percutaneous mitral balloon valvuloplasty (PMBV) on right ventricular function in the long term using tissue Doppler imaging. STUDY DESIGN Twenty-seven patients who underwent successful PMBV were enrolled in the study. Echocardiographic examination, including color tissue Doppler imaging, was done from the lateral tricuspid annulus 24 hours before the intervention, and the examination was repeated 24 hours and 6 months after the intervention. RESULTS At 24 hours after the intervention, S wave velocity and A' wave velocity were seen to have increased significantly (9.52±1.85 cm/s vs. 10.92±1.20 cm/s, p=0.012; -10.44±2.64 cm/s vs. -11.73±2.05 cm/s, p=0.029, respectively). E' wave velocity and E'/A' ratio did not change significantly (p>0.05 for both). In the late period, S wave velocity was similar to the value in the early period and significantly higher than the basal level (9.52±1.85 cm/s vs. 10.69±1.72 cm/s, p=0.023). However, A' wave velocity in the late period was decreased compared to the early period and was not different from the basal level (-10.44±2.64 cm/s vs. -10.74±2.63 cm/s, p>0.05). The increase in E' wave velocity in the late period when compared to the basal level was found to be statistically significant (-7.85±1.54 cm/s vs. -9.21±1.81 cm/s, p=0.046). CONCLUSION Right ventricular systolic function improved in the early period, and this improvement was seen to continue in the late period of PMBV. Diastolic function did not improve in the early period, but did improve in the late period. Right atrium systolic function improved in the early period; however, in the late period, levels were similar to the basal levels.

Abstract
OBJECTIVE Sleep is a vital function for human beings, which can be affected by several factors. Chronic pain is one of these factors where it is the most frequent cause for seeking medical care in combination with insomnia. The aim of this study is to examine the prevalence and relationship between sleep disturbance and chronic pain. PATIENTS AND METHODS After approval, a total of 85 Family Medicine Units from over 170 in Tokat were randomly selected using a 50% sampling. A sample of 2635 subjects, over the age of 19 years, who were registered with the selected Family Medicine Units, were assessed due to gender, age group, and the urban/rural population size of Tokat using the stratified sampling method. The sample size distribution was calculated as 1515 urban subjects, 1120 rural subjects; 1345 female subjects, 1290 male subjects; 1123 subjects between 20-39 years of age, 1103 subjects between the ages of 40-64, and 409 subjects over 64 years of age. After sampling, subjects were invited to participate in the study via an invitation letter, and agreeing individuals were taken to the Family Medicine Unit for face-to-face meetings. Written, informed consent was obtained, along with demographic data. The presence of chronic pain was recorded. According to the presence of chronic pain, all subjects were separated into two groups as Group Chronic Pain and Group Non-Chronic Pain. The visual analog scale for pain intensity, and Pittsburgh Sleep Quality Index for sleep quality, were performed with all subjects. A multiple linear regression model was used to assess the predictors of sleep quality. Analyses were conducted using the Statistical Package for Social Sciences program (SPSS Inc., Chicago, IL, USA), version 20.0. The statistical significance for all analyses was set at p < 0.05. RESULTS The mean global Pittsburgh Sleep Quality Index score of Group Chronic Pain (5.30 ± 4.29) was significantly higher than in Group Non-Chronic Pain (3.22 ± 3.30; p < 0.01). The mean Pittsburgh Sleep Quality Index scores of females (5.69 ± 4.40) were significantly higher than males (4.54 ± 3.96) in Group Chronic Pain (p = 0.000045). A total of 40.7% of patients in Group Chronic Pain, and 21.9% in Group Non-Chronic Pain demonstrated poorer sleep quality according to the Pittsburgh Sleep Quality Index scores, with a cut-off level > 5. A moderate positive correlation was found between the global Pittsburgh Sleep Quality Index and Visual Analog Scale scores (r = 0.310, p < 0.01). A multiple linear regression analysis showed that age, gender, income, Visual Analog Scale, and presence of depression were the significant predictors for Pittsburgh Sleep Quality Index score. CONCLUSIONS The current study revealed that chronic pain and pain intensity are important predictors of sleep quality.

Abstract
BACKGROUND Non-invasive prediction of paroxysmal atrial fibrillation (PAF) is one of the most recent interests of cardiology. AIM The current study investigates the relationship between the atrial electromechanical coupling time (EMCT) and PAF. PATIENTS AND METHODS A group of 35 patients with PAF was compared with a group of 37 subjects without PAF. Pulsed wave tissue Doppler evaluations of atrial walls were performed from apical four chambers view under ECG monitoring. The time intervals from the onset of P wave to the onset of late diastolic wave (A') at right atrial wall (P-RA), interatrial septum (P-IAS), and left atrial wall (P-LA, maximum EMCT) were measured. The right atrial EMCT (P-RA minus P-IAS), left atrial EMCT (P-LA minus P-IAS) and interatrial EMCT (P-LA minus P-RA) were computed. A' wave velocities were measured from each atrial wall. RESULTS RA (16.0±13.1 vs. -8.7±18.6 ms, p < 0.001) and maximum (91.5±32.6 vs. 72.0±23.1 ms, p = 0.001) EMCT were longer, RA A' velocity was higher in the patient group. There were no differences between the groups in LA and interatrial EMCT, and septal and LA A' velocities. Regression analysis revealed that only RA [OR: 1.148 (1.041-1.267), p = 0.006] and maximum [OR: 1.099 (1.009-1.197), p = 0.031] EMCT were independent variables for PAF. In order to predict patients with PAF, we have chosen +7.5 msn for the RA EMCT which yielded 69% sensitivity and 71.4% specificity to predict patients. CONCLUSIONS Delayed RA lateral EMCT relative to septal one and delayed maximum EMCT detected by tissue Doppler could be a valuable method for identifying patients with PAF.

Abstract
BACKGROUND Isoflurane is a volatile anaesthetic that has been commonly used since 1980. The major metabolites of isoflurane are fluoride ion and trifluoroacetate, both excreted in the urine. AIM This study manage to show the histopathological findings of ingested isoflurane on liver, kidney and lugs in an animal model. Twenty-one rabbits were selected and divided into three groups: Group Isoflurane-5 (I-5); Group Isoflurane-10 (I-10); and Group Control (C). Each group consisted of seven rabbits. I-5 and I-10 received 5 ml/kg and 10 ml/kg of liquid isoflurane, respectively, via nasogastric tube, while C received 5 ml/kg saline (0.9% NaCI). All animals in I-5 and I-10 were sacrificed without anesthetic drug administration. Tissue samples from livers, kidneys and lungs were collected, preserving tissue unity and avoiding infliction of any trauma. Samples were fixed in 10% formalin solution, embedded in paraffin blocks and sliced into 5 μm sections. To investigate the effects of isoflurane, sections were examined under light microscope and histopathological changes were scored. RESULTS Mean injury scores and the appearance of portal lymphocyte infiltration in liver samples showed significant increases in I-5 and I-10 compared to C (p = 0.005, p = 0.001 and p = 0.001, respectively). Mean lung injury scores revealed significant increases after isoflurane treatment in I-5 and I-10 compared to C (p = 0.026 and p = 0.017, respectively). CONCLUSIONS Ingested isoflurane led to mild liver and lung injuries in rabbits.

Abstract
All prosthetic valves are at least mildly stenotic and have relatively high transvalvular pressure gradients that can be observed despite normal prosthesis function. Such gradients may be due to a mismatch between prosthesis effective orifice area (EOA) and patient's body size. Valve prosthesis-patient mismatch (VP-PM) may occur due to mismatches of both parameters, the expected hemodynamic performance of the prosthesis and the cardiac output requirements of the patient, which are largely related to the body size at rest. In other words, a prosthesis may be adequate for patients with a small body surface area (BSA) but might become obstructive for patients with a large BSA. The only parameter that has proven to be consistently and realistically useful to predict and describe VP-PM is the effective orifice area index (EOAI). The projected EOAI was identified as the best parameter to predict the VP-PM occurrence after surgery. VP-PM has been known to be independently and significantly associated with clinical outcomes. Severe VP-PM has a significant impact on early and late mortality, whereas moderate VP-PM may have a significant effect on mortality only in vulnerable subsets of patients, and particularly in those with depressed LV systolic function. The surgeon's anticipation of VP-PM prior to surgery, and successfully implented preventive strategies can reduce the incidence of VP-PM. Preventive strategies to avoid VP-PM should be individualized according to the anticipated severity of VP-PM and of the patient's baseline risk profile.
