- Abstract
BACKGROUND Pembrolizumab has efficacy in programmed death ligand 1 (PD-L1)–positive metastatic or unresectable cervical cancer that has progressed during chemotherapy. We assessed the relative benefit of adding pembrolizumab to chemotherapy with or without bevacizumab. METHODS In a double-blind, phase 3 trial, we randomly assigned patients with persistent, recurrent, or metastatic cervical cancer in a 1:1 ratio to receive pembrolizumab (200 mg) or placebo every 3 weeks for up to 35 cycles plus platinum-based chemotherapy and, per investigator discretion, bevacizumab. The dual primary end points were progression-free survival and overall survival, each tested sequentially in patients with a PD-L1 combined positive score of 1 or more, in the intention-to-treat population, and in patients with a PD-L1 combined positive score of 10 or more. The combined positive score is defined as the number of PD-L1–staining cells divided by the total number of viable tumor cells, multiplied by 100. All results are from the protocol-specified first interim analysis. RESULTS In 548 patients with a PD-L1 combined positive score of 1 or more, median progression-free survival was 10.4 months in the pembrolizumab group and 8.2 months in the placebo group (hazard ratio for disease progression or death, 0.62; 95% confidence interval [CI], 0.50 to 0.77; P<0.001). In 617 patients in the intention-to-treat population, progression-free survival was 10.4 months and 8.2 months, respectively (hazard ratio, 0.65; 95% CI, 0.53 to 0.79; P<0.001). In 317 patients with a PD-L1 combined positive score of 10 or more, progression-free survival was 10.4 months and 8.1 months, respectively (hazard ratio, 0.58; 95% CI, 0.44 to 0.77; P<0.001). Overall survival at 24 months was 53.0% in the pembrolizumab group and 41.7% in the placebo group (hazard ratio for death, 0.64; 95% CI, 0.50 to 0.81; P<0.001), 50.4% and 40.4% (hazard ratio, 0.67; 95% CI, 0.54 to 0.84; P<0.001), and 54.4% and 44.6% (hazar

Aim: Epstein-Barr virus (EBV) infections are common among children and adults around the world. The clinical suspicion and identification of an Epstein-Barr virus (EBV) infection is critically important in the treatment of this disease. It is important to understand the regional distribution of EBV seropositivity for diagnosis and clinical approach. Therefore, the aim of this study was to investigate the regional EBV seropositivity in children and adults, differences in development of the disease and clinical changes over time. Materials and methods: The EBV viral-capsid antigen (VCA) IgM and EBV VCA/early antigen (EA) IgG test results of 6822 patients sent to a microbiology laboratory between January 2009 and December 2012 were included in to the study. Tests were conducted using the VIDAS(Biomérieux, France) system in accordance with the kit package insert. Results: The average age was 17.8 years (among 0-94 ages). Of the patients, 2166 (31.8%) were adults, and 4656 (68.2%) were children. A total of 2677 of the children (57.5%) were male, and 1979 (42.5%) were female. There were 1036 (47.8%)male and 1130 (52.2%) female adults. Acute infection was detected in 422 of the patients (6.6%). 342 (81%) of these patients were children. Previous infection was present in 4875 patients (71.7%). Of the children, 7.3% were acute cases. A total of 3.7% of the patients were adult acute cases. Adult patients with previous infection numbered 89.5%, while 63.3% of them were children in this group. There were 1525 (22.4%) seronegative patients. Of these, 1378 were children (90.4%), and 147 (9.6%) were adults. Encountering rate with EBV infectionsdecreased and seronegativity increased with time. Conclusion: The 22.4% measurement of seronegativity among thepatients in our regionsuggests that personal precaution trainingis effective. This situation is consistent with the decreased seronegativity in children over time.

Glomus tumors, also known as paragangliomas or chemodectomas, arise from welldifferentiated mesenchymal cells that are known to be benign. These tumors account for 2% of all soft tissue tumors. The first case of a cardiac glomus tumor was reported in 1924 by Masson.1 Glomus tumors located within the pericardial tissue are extremely rare. We present the case of a recurrent cardiac glomus tumor. The preoperative investigation, diagnostic problems and surgical treatment of this case will be highlighted. Moreover we wish to emphasize the importance of such an entity and to remind readers that it must be included in the differential diagnosis of a pericardial tumor [ABSTRACT FROM AUTHOR]

- Abstract
Background: Cardiac allograft rejection and vasculopathy are the main factors limiting long-term survival after heart transplantation.In this pilot study we investigated whether non-invasive methods are beneficial to detect cardiac allograft rejection (Grade 03 R) and cardiac allograft vasculopathy. Thus we compared multi-slice computed tomography and magnetic resonance imaging with invasive methods like coronary angiography and left endomyocardial biopsy.Methods: 10 asymptomatic long-term survivors after heart transplantation (8 male, 2 female, mean age 52.1 +/- 12 years, 73 +/- 11 months after transplantation) were included. In a blinded fashion, coronary angiography and multi-slice computed tomography and ventricular endomyocardial biopsy and magnetic resonance imaging were compared against each other.Results: Cardiac allograft vasculopathy and atherosclerosis were correctly detected by multi-slice computed tomography and coronary angiography with positive correlation (r = 1). Late contrast enchancement found by magnetic resonance imaging correlated positively (r = 0.92, r2 = 0.85, p < 0.05) with the histological diagnosis of transplant rejection revealed by myocardial biopsy. None of the examined endomyocardial specimen revealed cardiac allograft rejection greater than Grade 1 R.Conclusion: A combined non-invasive approach using multi-slice computed tomography and magnetic resonance imaging may help to assess cardiac allograft vasculopathy and cardiac allograft rejection after heart transplantation before applying more invasive methods.

Pembrolizumab has efficacy in programmed death ligand 1 (PD-L1)-positive metastatic or unresectable cervical cancer that has progressed during chemotherapy. We assessed the relative benefit of adding pembrolizumab to chemotherapy with or without bevacizumab.In a double-blind, phase 3 trial, we randomly assigned patients with persistent, recurrent, or metastatic cervical cancer in a 1:1 ratio to receive pembrolizumab (200 mg) or placebo every 3 weeks for up to 35 cycles plus platinum-based chemotherapy and, per investigator discretion, bevacizumab. The dual primary end points were progression-free survival and overall survival, each tested sequentially in patients with a PD-L1 combined positive score of 1 or more, in the intention-to-treat population, and in patients with a PD-L1 combined positive score of 10 or more. The combined positive score is defined as the number of PD-L1-staining cells divided by the total number of viable tumor cells, multiplied by 100. All results are from the protocol-specified first interim analysis.In 548 patients with a PD-L1 combined positive score of 1 or more, median progression-free survival was 10.4 months in the pembrolizumab group and 8.2 months in the placebo group (hazard ratio for disease progression or death, 0.62; 95% confidence interval [CI], 0.50 to 0.77; P0.001). In 617 patients in the intention-to-treat population, progression-free survival was 10.4 months and 8.2 months, respectively (hazard ratio, 0.65; 95% CI, 0.53 to 0.79; P0.001). In 317 patients with a PD-L1 combined positive score of 10 or more, progression-free survival was 10.4 months and 8.1 months, respectively (hazard ratio, 0.58; 95% CI, 0.44 to 0.77; P0.001). Overall survival at 24 months was 53.0% in the pembrolizumab group and 41.7% in the placebo group (hazard ratio for death, 0.64; 95% CI, 0.50 to 0.81; P0.001), 50.4% and 40.4% (hazard ratio, 0.67; 95% CI, 0.54 to 0.84; P0.001), and 54.4% and 44.6% (hazard ratio, 0.61; 95% CI, 0.44 to 0.84; P = 0.001), respectively. The most common grade 3 to 5 adverse events were anemia (30.3% in the pembrolizumab group and 26.9% in the placebo group) and neutropenia (12.4% and 9.7%, respectively).Progression-free and overall survival were significantly longer with pembrolizumab than with placebo among patients with persistent, recurrent, or metastatic cervical cancer who were also receiving chemotherapy with or without bevacizumab.

In recent years, much research has been performed in order to decrease fuel consumption, noise, and exhaust emission levels in internal combustion engines. In this study, the effects of excess air coefficient on performance and exhaust emissions (CO, CO2) of an HCCI engine fueled with primary reference fuel (PRF) were investigated for different intake air pressure and temperature values. The simulation studies were performed by using SRM Suite software. The chemical kinetic mechanism, which contains 138 species and 633 reactions that are embedded into the program, was used to simulate the combustion of the PRF fuel during the combustion simulations. The analysis covers the full cycle and provides data about induction, compression, combustion, expansion, and exhaust. The exhaust emissions, cylinder pressure, and heat release rate results were compared with the experimental data. The zero-dimensional software (SRM Suite) gives quite reasonable results compared with the experimental data, and it has advantages such as the shorter solution time and the unlimited chemical kinetic mechanism compared with the three-dimensional combustion simulation software.

This study was conducted in order to determine the effect of silverthiosulphate + sucrose pretreatment on the cold storage period and post storage vase life of cut flowers of carnation cv. Astor harvested at different maturities. Chemical pretreatments were not effective on the storage period of the cut flowers. Flowers at tight cluster stage (tight bud) were stored for 105 days which was the longest time. Chemical pretreatment, however, was found to be very effective on the vase life of cut carnations. Flowers at the right harvest maturity and those which not been stored showed the longest vase life. Chemical pretreatment, short storage period and flowers at paint brush stage gave the best results on opening time of the flowers dipped in the solution at bud stage. The best result were obtained from chemical pretreatment inflower diameter, 2 months stored flowers and the flowers at paint brush stage also had a high flower diameter.

- Abstract
Objective: The aim of this study is to examine the impact of carbohydrate ratios in the diet consumed one day prior to the 75-g oral glucose screening test on both the screening test values and the diagnosis of gestational diabetes mellitus in the unselective pregnant population., Material-Method: 83 pregnant women who were under observation in the antenatal clinic of our hospital and underwent glucose tolerance tests were included in the study. The patients were given training by a dietitian to keep nutrition records of the day prior to glucose loading during their previous visits before any glucose loading. A carbohydrate intake of 40-60% was considered as the normal range in terms of the percentage of carbohydrates in the diet. A carbohydrate percentage above 60% was considered to be a high carbohydrate intake. The carbohydrate percentages in their diet over the past 24 hours was compared with the effect on the glucose tolerance test., Results: Out of the 83 pregnant women included in the study, 40 of them had a high carbohydrate diet (HCD) prior to the oral glucose tolerance test (OGTT), and the average carbohydrate percentage of this diet was found to be 62%. The remaining 43 patients had an average carbohydrate percentage of 49% and belonged to the group that had a normal carbohydrate diet (NCD). Out of the 83 pregnant women, 33 of them were at high risk for gestational diabetes mellitus (GDM). In the high-risk patient group, 16 patients had an NCD intake, while 17 patients had a HCD intake. It was determined that a high carbohydrate diet had no significant effect on fasting, first-hour, and second-hour glucose levels, as well as the diagnosis of gestational diabetes mellitus (GDM), in both the unselective population and the high-risk patient population., Conclusion: In our study, we concluded that the high carbohydrate ratios in the diets of pregnant women one day prior did not affect the OGTT results or the GDM ratios. This indicates that there is no need for a preparatory diet prior to the OGTT in women with normal dietary habits., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

- Abstract
Background: Our group focused on a meso‑aryl substituted porphyrin molecule for its photodynamic anti-inflammatory activities on the mammalian macrophages., Materials and Methods: The porphyrine derivative previously synthesized in this study was synthesized and characterized by
1 H NMR. We then examined their immunomodulatory activities based on the changes in the pro-inflammatory cytokine production levels after LPS stimulation in dark and light activated conditions., Results: Our results suggest that porphyrin derivative had anti-inflammatory photodynamic activity in vitro at subtoxic concentrations. Our study aims to pave a way for anti-inflammatory photodynamic therapy application in the inflammatory and autoimmune disorders. Most of the studies either focus on photodynamic cytotoxicity of the porphyrin derivatives to suppress the inflammation or porphyrin derivatives' anti-inflammatory activity without the photodynamic activation., Conclusion: Our future studies will focus on the generation and in vitro as well as in vivo characterization of the porphyrin derivatives with anti-inflammatory photodynamic therapy applications. In this way, novel drug candidates that would have lower side effects can be generated for the patients., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflicts of interest., (Copyright © 2023.

- Abstract
Everolimus is a mTOR inhibitor that has been increasingly used in high-risk cardiac rhabdomyomas in recent years. There are questions regarding the optimal dose and duration of therapy with everolimus for cardiac rhabdomyomas. The purpose of this study was to examine retrospectively the dosage-efficacy relationship in seven babies diagnosed with rhabdomyoma treated with different everolimus dose regimens retrospectively. Cardiac rhabdomyoma diagnosis was made in six of seven babies during the prenatal period. Indication of everolimus was an obstruction in six patients and supraventricular tachycardia which is resistant to antiarrhythmic drugs in the remaining one patient. The median age was 8 days (range; 2-105 days) at the time of starting everolimus. It was administered at a dose of 0.25 mg twice a day for two days a week in four patients; 0.1 mg/day in two and 0.4 mg/day in one patient. Serum everolimus level was kept between 5 and 15 ng/ml. All seven cases showed significant regression of cardiac rhabdomyoma within four weeks, and supraventricular tachycardia was controlled in two weeks after everolimus administration.This study demonstrates that everolimus was effective in accelerating regression of the cardiac rhabdomyoma. Dose with 2 × 0,25 mg/day, 2 days a week, seems appropriate. However, lower doses such as 0.1 mg/day are also effective. But dose adjustment should be made according to serum level monitoring.

- Abstract
Objective: The aim of this study is to investigate the relationship between flexible pes planus (FPP) and cardiac pathologies in pediatric patients, with a particular emphasis on hypermobility status., Methods: Between January and June 2022, a retrospective screening was conducted on a total of 68 patients aged between 6 and 18 years who had been diagnosed with FPP. Eight patients were excluded from the study due to suspicion of connective tissue or neuromuscular diseases following systemic examinations conducted by a pediatric specialist. The included 60 patients underwent comprehensive cardiac examinations conducted by pediatric cardiology specialists and were evaluated through echocardiography (ECHO) as part of the study. Simultaneously, a control group of healthy individuals aged 6 to 18, without a diagnosis of pes planus (PP), was selected from those who applied for health reports for the purpose of obtaining sports licenses. Patients diagnosed with FPP were compared to a control group in terms of the presence of cardiac pathology. Furthermore, the Beighton Hypermobility Scores (BHSs) of patients diagnosed with FPP were compared based on the presence of cardiac pathology., Results: A total of 60 patients (40 males, 20 females) diagnosed with FPP were included in the study, and a control group consisting of 453 healthy individuals (287 males, 166 females) was selected. The incidence of cardiac pathology in patients diagnosed with FPP (23.3%) was found to be significantly higher compared to the control group (7%) (p <0.01). The risk of cardiac pathology in patients diagnosed with FPP was determined to be four times higher compared to the control group (Odds ratio: 4 (1.993-8.046), p<0.01). Among patients with FPP, individuals who were found to have cardiac pathology had statistically significantly higher average BHSs compared to those without cardiac pathology (p: 0.043)., Conclusions: Our study suggested that there may be a significant relationship between FPP and high cardiac pathology risk in pediatric patients. We observed a significant increase in the incidence of cardiac pathologies among patients diagnosed with FPP. Additionally, the presence of higher hypermobility scores among patients diagnosed with FPP suggests a potential connection between the two. In the evaluation of FPP in the pediatric population, it should be considered as a potential risk factor for cardiac pathologies and its potential association with hypermobility., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Karatekin et al.)

- Abstract
Objective: The aim of the study was to evaluate the early myocardial dysfunction detected by strain echocardiography in children with multisystem inflammatory syndrome related to SARS-CoV-2 infection., Methods: This cross-sectional study was conducted with 47 patients diagnosed with MIS-C and 32 healthy age- and gender-matched children. All patients underwent two-dimensional, colour, pulsed, and tissue Doppler, and 2D speckle tracking echocardiography examination at admission, 2 weeks, and 2 months after discharge. The MIS-C patient group was compared with the control group. Echocardiographic changes in MIS-C patients during follow-up were evaluated., Results: Of 47 patients, 30 (63.8%) were male and 17 (36.2%) were female. The mean age at diagnosis was 9.1 ± 4.3 (1.25-17) years. At admission, 25 patients had abnormal findings on conventional echocardiography. Among them, eight patients had left ventricular systolic dysfunction. Ejection fraction and fractional shortening were significantly lower in the patient group at admission compared to controls (p = 0.013, p = 0.010, respectively). While the ejection fraction was <55% in eight patients, and global longitudinal strain was lower than -2SD in 29 patients at admission. Global longitudinal strain z-score <-2SD persisted in 13 patients at 2-month follow-up. Ejection fraction increased above 55% in 3.42 ± 0.53 days in 7 of 8 patients with left ventricular systolic dysfunction, ejection fraction was 51% at discharge in one patient, and left ventricular systolic dysfunction persisted at the 6-month of follow-up., Conclusion: These results confirmed that speckle tracking echocardiography is more likely to detect subclinical myocardial damage compared to conventional echocardiography. In addition, it is a valuable method for follow-up in this patient group.

- Abstract
Objectives: To describe fetal spectrum and echocardiographic characteristics of interrupted inferior vena cava (IIVC) with azygos/hemiazygous continuation without other structural heart defects and to evaluate its association with visceral heterotaxy and isomerism, extracardiac and genetic anomalies, and to review neonatal outcome., Methods: This was a retrospective study of 14 fetuses with a confirmed diagnosis of IIVC with normal intracardiac anatomy. The following variables were collected; indication for referral, gestational age at diagnosis; associated isomerism and visceral heterotaxy, heart rhythm, genetic and extracardiac abnormalities, and fetal/neonatal outcome., Results: Among 36 fetuses with IIVC, 14 cases (38.8%) had normal intracardiac anatomy. These IIVC cases correspond to 0.19% (14/7250) of all fetal cardiac examinations, and to 1.5% (14/922) of all cardiac abnormalities. Six patients had visceral abnormalities. Atrial appendage morphology was clearly depicted in three fetuses, both appendages were left. One fetus had bradyarrhythmia revealing atrial ectopic rhythm. Six fetuses did not have any concomitant cardiac or visceral abnormalities, therefore regarded as isolated. All babies were delivered at term with a good prognosis., Conclusion: Our study has shown that almost half of the IIVC cases without intracardiac structural anomalies displayed other findings of isomerism while the other half was isolated benign vascular variant. Therefore, prenatal diagnosis of IIVC should prompt a comprehensive evaluation for cardiac, situs, and visceral anomalies. The outcome is favorable., (© 2022 Wiley Periodicals LLC.)

- Abstract
Background and Objectives: Literature does not show any studies regarding plate placement problems in the coronal plane of patients with volar plating due to distal radius fracture diagnosis. We aimed to investigate the functional and laboratory results of the coronal malposition of the volar locking plate in patients with distal radius fracture treated with internal fixation., Methods: In this retrospective study, we included patients who had volar plate fixation, were aged between 18 and 80, had no pathological fracture, had a minimum of six months of follow-up, and had the same rehabilitation protocol. We consider the angle subtended on the coronal axis between the distal radius long axis and the distal radius locking plate as coronal malposition. We named the coronal malposition angle the "AYE Angle." Patients with an AYE angle of over 1 degree were evaluated under group 1. Patients with an AYE angle of 0-1 degrees were evaluated under group 2. Radiological parameters were taken from AP-Lateral X-ray views. Superficial University System of Georgia (USG) examinations were applied to detect tendon problems. The DASH and QUICK-DASH scoring systems were used for clinical evaluation. Grip strength was measured with a dynamometer in all patients. All results were compared between the two groups., Results: Thirteen patients were female and 27 patients were male. Nineteen patients who had coronal malposition were added to group 1, while 21 patients who had no coronal malposition were added to group 2. Fifteen patients had normal USG results in group 2, while 18 patients had edema around the flexor pollicis longus (FPL) tendon as a result of USG in group 1. Statistically, a significant difference was detected between the two groups in terms of the amount of tenosynovitis around FPL (p=0.01). A statistically significant relationship was found between USG grading and malposition grading. The study revealed that a higher rate of USG grade 2 was found in patients with malposition grade 2 (90.9%), while a higher rate of USG grade 1 (50%) was observed in patients with malposition grade 1 (p=0.01). A statistically significant difference was not found between Soong grading and USG in terms of the level of tenosynovitis around the FPL tendon. The amount of tenosynovitis detected around the FPL tendon was 62.5% for Soong and grade 0 level, 60.7% for grade 1 level, and 50% for grade 2 level. There was no statistically significant difference between the two groups in the DASH and QUICK-DASH scoring systems (p=0.96). There was no statistically significant difference between the two groups in the grip strength (p=0.52)., Conclusion: Coronal plate position in the treatment of the distal radius fracture is important to avoid potential flexor tendon problems. The volar plate position should be adjusted properly both in the coronal and sagittal axes., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Usta et al.)

- Abstract
Background: Pembrolizumab has efficacy in programmed death ligand 1 (PD-L1)-positive metastatic or unresectable cervical cancer that has progressed during chemotherapy. We assessed the relative benefit of adding pembrolizumab to chemotherapy with or without bevacizumab., Methods: In a double-blind, phase 3 trial, we randomly assigned patients with persistent, recurrent, or metastatic cervical cancer in a 1:1 ratio to receive pembrolizumab (200 mg) or placebo every 3 weeks for up to 35 cycles plus platinum-based chemotherapy and, per investigator discretion, bevacizumab. The dual primary end points were progression-free survival and overall survival, each tested sequentially in patients with a PD-L1 combined positive score of 1 or more, in the intention-to-treat population, and in patients with a PD-L1 combined positive score of 10 or more. The combined positive score is defined as the number of PD-L1-staining cells divided by the total number of viable tumor cells, multiplied by 100. All results are from the protocol-specified first interim analysis., Results: In 548 patients with a PD-L1 combined positive score of 1 or more, median progression-free survival was 10.4 months in the pembrolizumab group and 8.2 months in the placebo group (hazard ratio for disease progression or death, 0.62; 95% confidence interval [CI], 0.50 to 0.77; P<0.001). In 617 patients in the intention-to-treat population, progression-free survival was 10.4 months and 8.2 months, respectively (hazard ratio, 0.65; 95% CI, 0.53 to 0.79; P<0.001). In 317 patients with a PD-L1 combined positive score of 10 or more, progression-free survival was 10.4 months and 8.1 months, respectively (hazard ratio, 0.58; 95% CI, 0.44 to 0.77; P<0.001). Overall survival at 24 months was 53.0% in the pembrolizumab group and 41.7% in the placebo group (hazard ratio for death, 0.64; 95% CI, 0.50 to 0.81; P<0.001), 50.4% and 40.4% (hazard ratio, 0.67; 95% CI, 0.54 to 0.84; P<0.001), and 54.4% and 44.6% (hazard ratio, 0.61; 95% CI, 0.44 to 0.84; P = 0.001), respectively. The most common grade 3 to 5 adverse events were anemia (30.3% in the pembrolizumab group and 26.9% in the placebo group) and neutropenia (12.4% and 9.7%, respectively)., Conclusions: Progression-free and overall survival were significantly longer with pembrolizumab than with placebo among patients with persistent, recurrent, or metastatic cervical cancer who were also receiving chemotherapy with or without bevacizumab.

- Abstract
This study was conducted in order to determine factors that influence self-transcendence and meaning in life in the elderly receiving institutional care. This descriptive and analytic study was conducted on 72 elderly individuals living in a nursing home in Turkey. Data were collected with the Barthel Index of Activities of Daily Living (ADL), the Lawton&Brody Instrumental Activities of Daily Living (IADL), the Meaning in Life Questionnaire (MLQ) and the Self-Transcendence Scale (STS). The mean score of STS is 48.17 ± 6.67 at the intermediate level, and the mean scores of presence and search subscales of the MLQ are 28.07 ± 6.55 and 24.06 ± 7.73 above the intermediate level. The STS mean score is poorly correlated with the ADL (r = 0.277) and the IADL scale (r = 0.343). Increased perception of general health status of the elderly improved self-transcendence (ST) level (p = 0.04) and search for meaning in life (ML) level (p = 0.02). These findings show that the health perceptions of the elderly must be improved in the first place.

- Abstract
Background: Percutaneous mitral balloon valvuloplasty and mitral valve replacement have been the treatment options for mitral stenosis for several years, however, studies that compare these two modalities are very rare in the literature., Objective: In this article, we aim to investigate the comparison of clinical results of percutaneous mitral balloon valvuloplasty and mitral valve replacement., Methods: 527 patients with rheumatic mitral stenosis, treated with percutaneous mitral balloon valvuloplasty or mitral valve replacement (276 patients with percutaneous mitral balloon valvuloplasty and 251 patients with mitral valve replacement) from 1991 to 2012 were evaluated. The demographic characteristics, clinical, echocardiographic and catheterization data of patients were evaluated retrospectively. The results of early and late clinical follow-up of patients after percutaneous mitral balloon valvuloplasty and mitral valve replacement were also evaluated., Results: The mean follow-up time of the percutaneous mitral balloon valvuloplasty group was 4.7 years and, for the mitral valve replacement-group, it was 5.45 years. The hospital stay of the percutaneous mitral balloon valvuloplasty group was shorter than that of the mitral valve replacement group (2.02 days vs 10.62 days, p<0.001). The hospital mortality rate of percutaneous mitral balloon valvuloplasty and mitral valve replacement were 0% and 2% respectively (p=0.024). In the percutaneous mitral balloon valvuloplasty group, early postprocedural success rate was 92.1%. The event-free survival of percutaneous mitral balloon valvuloplasty and mitral valve replacement was found to be similar. While reintervention was higher in percutaneous mitral balloon valvuloplasty-group (p<0.001), mortality rate was higher in mitral valve replacement-group (p<0.001)., Conclusion: Percutaneous mitral balloon valvuloplasty seems to be more advantageous than mitral valve replacement due to low mortality rates, easy application of the procedure and no need for general anesthesia.

- Abstract
Background: Despite the presence of several clinical studies evaluating the association of atherosclerosis and MAC, no data is present regarding the value of MAC in predicting CV adverse events in patients with acute coronary syndrome (ACS). Methods: Prospective, observational cohort study including 314 patients presented with ACS and underwent percutaneous coronary intervention (PCI). MAC was defined by increased echodensity located at the junction of the atrioventricular groove and posterior mitral leaflet on the parasternal long-axis, short-axis, or apical four-chamber view. Patients were followed for a median 25.1 (23.1-26.5) months for any occurrence of major adverse cardiovascular events (MACE). Results: Among 316 patients 46 (14%) had MAC. Seventy (22.1%) patients had MACE during the follow-up. Patients with MACE had higher creatinine, white blood cell count (WBC), C-reactive protein (CRP), peak troponin I, glucose level at admission compared to those without MACE. Age (HR = 1.026, 95% CI = 1.004-1.049; p = .023), myocardial blush grade (HR = 0.637, 95% CI = 0.480-0.846; p = .008), MAC (HR = 2.429, 95% CI = 1.126-5.239; p = .026), and WBC at admission (HR = 1.079, 95% CI = 1.007-1.157; p = .031) were independent predictors for MACE. Conclusion: In patients presented with ACS and underwent PCI, MAC detected by TTE was an independent predictor for MACE during the long-term follow-up.

- Abstract
Objective: Uncontrolled inflammatory responses could contribute to the pathogenesis of many leading causes of human morbidity and mortality. Aspirin is an anti-inflammatory and antithrombotic drug that is used in the primary and secondary protection in atherothrombotic diseases and complications. The aim of the present study was to analyze the effect of aspirin resistance on the extent and severity of atherosclerosis., Methods: One hundred patients who underwent coronary angiography with suspected or known coronary artery disease and were using aspirin were enrolled in the study., Results: Of these 100 patients, 30 (8 female and 22 male) formed the aspirin-resistant group (ARG), and 70 (22 female and 48 male) formed the control group. Gensini scoring system (GSS) was significantly higher in the ARG than in the control group (80.5 (36-166) vs. 45 (2-209); p<0.001). The number of percutaneous coronary intervention (PCI) patients was significantly higher in the ARG (13 of 30 (43.3%) ARG vs. 13 of 70 (18.6%) control group; p=0.01). Furthermore, when we evaluate the 16 reintervention patients, stent restenosis was significantly higher in the ARG (11 of 16 (68.75%) ARG vs. 5 of 16 (31.25%) control group; p=0.016). Multivariate logistic regression analysis revealed that GSS (p=0.038; 95% CI: 1.001-1.026) and PCI history (p=0.017; 95% CI: 1.182-89.804) were independent risk factors for aspirin resistance., Conclusion: In conclusion, atherosclerotic burden as calculated by the GSS is significantly higher in aspirin-resistant patients. According to this result, we suggest that aspirin treatment can be prescribed in higher doses in aspirin resistance patients with coronary events. Furthermore, GSS and PCI history could be independent predictors of aspirin resistance., Competing Interests: Conflict of Interest: The authors declare no conflict of interest.

- Abstract
Spiritual care means helping an individual protect, maintain and gain all the dimensions of his/her existence. Elderly care technicians face numerous cases or crisis situations in which elderly individuals from different backgrounds question the meaning and value of life. Elderly care technicians must acknowledge that the spirituality is an important element in the way an elderly individual receives healthcare and they must be equipped for this matter. This study was conducted in order to examine the influence of "Skill Development Training Program for Spiritual Care of Elderly Individual," which was carried out with students from elderly care program, on the perception of spirituality support in a pretest-posttest quasi-experimental study design with control group. As the data collection form, "Spiritual Support Perception" (SSP) scale was used. The mean scores of the intervention group after the training and after one month are 50.39 ± 5.34 and 51.13 ± 4.98, respectively, and those of the control group are 43.16 ± 4.83 and 42.72 ± 4.48. A statistically significant difference was found between the mean scores of the intervention group from the pretest and the posttests immediately after the training and one month after the training (f = 94.247, p = 0.001). In the control group, however, there was no significant change in the SSP mean scores (f = 0.269, p = 0.77). As a result, this study pointed out the necessity of such training programs for healthcare professionals to make a distinction between their professional duties and their own personalities in order to offer spiritual care to the elderly individual.

- Abstract
Objective: Clopidogrel inhibits platelet aggregation by blockade of platelet adenosine diphosphate (ADP) P2Y12 receptor. Leptin is the obesity gene product, and its serum level increases with obesity. Platelets have leptin receptors on their surfaces. Hyperleptinemia may induce ADP-mediated platelet aggregation. It has been proposed that clopidogrel effect could be diminished with high serum leptin levels. The aim of the present trial was to further investigate the relationship between serum leptin level and clopidogrel resistance., Methods: A total of 100 subjects who underwent percutaneous coronary intervention were enrolled. Two groups were organized according to presence of clopidogrel resistance, and serum leptin levels were compared. Threshold for clopidogrel resistance and hyperleptinemia were accepted as ≥P2Y12 reaction unit (PRU) 240 and ≥15 ng/mL leptin, respectively. Body mass index (BMI) of 30 kg/m2 or greater was considered obese., Results: A total of 37% of patients were considered clopidogrel-resistant. Comparison of groups revealed significantly higher clopidogrel resistance (p=0.017) and PRU levels (p=0.001) in hyperleptinemic patients. No significant difference in serum leptin levels (p=0.116) was found. Increased clopidogrel resistance was observed in patients with BMI >30 kg/m2 (p=0.015)., Conclusion: Clopidogrel resistance is more common in obese and hyperleptinemic patients. Dosage should be individualized in these populations.

- Abstract
Stenotrophomonas maltophilia is an opportunistic emergent pathogen causing hospital-acquired infections. It is resistant to majority of the broad spectrum antibiotics due to several mechanisms which significantly limit the treatment options. Although the relationship between integrons, mobile genetic elements which play role in transferring resistance genes, and the antibiotic resistance in different gram-negative bacteria have been investigated, the data are limited in Turkey especially for S.maltophilia. The aims of this study were to detect the presence of different classes of integrons and plasmids in clinical isolates of S.maltophilia and to investigate the antibiotic resistance profiles of those isolates. One hundred S.maltophilia strains isolated from various clinical samples (32 sputum, 25 tracheal aspirates, 9 urine and blood, 7 exudates and catheters, 4 sterile body fluids and wounds, 2 CSF, 1 conjunctiva) in our microbiology laboratory during January 2011-September 2012, were included in the study. The isolates were identified by VITEK2 Compact (BioMerieux, France) or Phoenix 100 (BD, USA) automatized systems, and the susceptibilities of the strains to levofloxacin, chloramphenicol, ceftazidime and trimethoprim/sulfamethoxazol (SXT) were evaluated via broth microdilution method according to the CLSI recommendations. Class 1 (intI-1), class 2 (intI-2), class 3 (intI-3) integron gene cassettes and integron 5'-3' conserved gene regions (intI-5'-3'CS) were investigated by polymerase chain reaction (PCR) using specific primers in all of the strains. Nucleotide sequence analysis of PCR products was performed in case of positive result, and the presence and size of plasmids were further investigated. The susceptibility rates of S.maltophilia strains to ceftazidime, chloramphenicol, SXT and levofloxacin were found as 24%, 66%, 93% and 95%, respectively, while MIC(50) and MIC(90) values were 64-128 µg/ml, 8-16 µg/ml, 1/19-2/38 µg/ml and 1-2 µg/ml, respectively. In PCR amplification with intI-1, intI-2 and intI-3 primers, 12%, 2% and 10% of the isolates yielded expectative bands, respectively. DNA sequence analysis of the amplified products revealed five isolates to harbour intI-1 gene, while intI class 2 and class 3 genes were not detected in any of the strains. Furthermore in PCR amplification with intI-5'CS and 3'CS primers, 20% of the strains yielded expected bands. Sequence analysis of these amplicons revealed the presence of quaternary ammonium compound resistance protein genes (qacL) in two, aminoglycoside adenyltransferase gene (aadA) in one and integron-associated recombination site (attI1) genes in five strains. Additionally, the presence of plasmids have been detected in 9 (9%) of the strains, however all of them was integron-negative. The sizes of plasmids were 2340, 1350, 2760, 18600, 20000, 3570-2540, 2510 and 5000-2540 base pairs, respectively. When the antibiotic susceptibility patterns of strains were compared with the presence of intI gene regions, no statistically significant relationship was observed (p> 0.05). In conclusion, the demonstration of integron class 1 genes and plasmids among clinical S.maltophilia strains is regarded as a warning data to indicate the potential for spread of those resistant strains in our hospital.

- Abstract
Background: The goal of this study was to measure an adverse event rate and determine the potential usefulness of the Institute for Healthcare Improvement's Global Trigger Tool (GTT). Besides using the GTT to measure the adverse event rate, a comparison was also made with the internal Voluntary Reporting Notification System (VRNS) to identify and compare the strengths and weaknesses of the two approaches., Method: Retrospective data were collected from reported patient safety incidents covering a one-year period at Duzce University Hospital, Turkey. Using a range of selection criteria, a total of 219 patient records were selected and then reviewed by a trained GTT team, to investigate the positive triggers in the content of the patient records., Results: It was determined that adverse events per 1000 patient days totalled 80.72. Adverse events per 100 admissions were 29.39, and the rate of admissions with adverse events was 16.67%. The comparison between the GTT and the VRNS showed that the GTT is 19 times more sensitive than the VRNS in the adverse event evaluation process., Conclusion: This is the first published study of the rate of adverse events in a Turkish healthcare setting using the GTT. It was found that the GTT was applicable in this setting, yielding more accurate measurement of the adverse event rate. However, the content of the GTT should be adjusted regarding the standards and documentations used in the Turkish healthcare system to be more useful.

- Abstract
Objective: Acute kidney injury (AKI) is common following cardiopulmonary bypass (CPB). The aim of this study is to determine the accuracy of urinary neutrophil gelatinase-associated lipocalin (NGAL) levels following cardiac surgery to establish the severity of renal impairment as compared to serum creatinine levels., Methods: A total number of 28 patients undergoing elective cardiopulmonary bypass were included. Diagnostic criteria of AKI was established in case of a percentage increase in serum creatinine concentration of >50%. Serum creatinine levels were recorded in the preoperative period before induction and in the postoperative period at 24, 48, and 72 hours. Urinary NGAL measurement was performed before induction and in the 4(th) postoperative hour. The duration of CPB surgery, hospital stay, and cross-clamp time were recorded., Results: Based on AKI criteria, subjects were grouped as AKI (n=11) and no AKI (n=19). Postoperative urinary NGAL levels were significantly higher in the group with AKI (11.8 ng mL(-1) vs. 104.0 ng mL(-1), p=0.003). In the AKI group, CPB time bypass (111.9 min vs. 82.7 min) and cross-clamp time (76.9 min vs. 59.1 min) were significantly higher. A cut-off of 25.5 ng mL(-1) yielded a sensitivity of 81.82% and a specificity of 94.12% at the postoperative 4(th) hour with an AUC of 0.947 for predication of AKI., Conclusion: Urine NGAL rose significantly much earlier as compared to serum creatinine levels in the early postoperative period. Although larger case series are needed, we are of the opinion that urinary NGAL measurements may be used as an early clinical marker of AKI following CPB.
