Objective: Bicuspid aortic valve (BAV) is a complex developmental anomaly caused by abnormal aortic leaflet formation during valvulogenesis. The present study is an assessment of the effects of BAV disease on the ascending aorta and pulmonary artery (PA), and an evaluation of the consequences for systolic and diastolic functioning of the left and right ventricles., Methods: Total of 66 patients were eligible for inclusion. Pulmonary artery maximum diameter (PAD) was obtained 1 cm distal to the pulmonary annulus. Using pulsed-wave tissue Doppler imaging, left ventricular (LV) early diastolic velocity (E') measurement was obtained at the annulus with placement of sample volume. Right ventricle (RV) peak global strain rate during systole (RV-SRS), early diastole (RV-SRE), and late diastole (RV-SRA) were calculated., Results: In this study, 40.9% (n=27) of patients were female and average age was 35±11years. RV-SRS values (ß=-.781, t=-2.723; p=0.010) and log-LV tissue Doppler imaging E' (ß=-2.996, t=-5.405; p=<0.001) were negatively correlated, and log-PAD (ß=4.861, t=3.052; p=0.005) was positively and independently correlated with ascending aortic diameter., Conclusion: Ascending aorta diameter is positively correlated with PA diameter in BAV patients, and RV strain rate and LV diastolic parameters are affected before development of the valve disease.

Restless legs syndrome (RLS) is a common health problem in patients on hemodialysis. This descriptive study was carried out with patients from a hemodialysis unit in the province of Eskişehir, Turkey. Of the 317 patients in the unit, 244 (77.0%) comprised the study group. RLS was assessed by diagnostic criteria defined by the International RLS Working Group, sleep quality by the Pittsburgh Sleep Quality Index, and depression by the Beck Depression Inventory. RLS was found in 15.6% of patients and was associated with depression and sleep quality. Sleep quality is impaired with the increasing severity of RLS. RLS is an important health problem in patients on hemodialysis., Competing Interests: The authors reported no actual or potential conflict of interest in relation to this continuing nursing education activity., (Copyright© by the American Nephrology Nurses Association.)

Objectives: The aim of this study was to analyze and compare the vocal quality in patients who underwent either submucosal turbinectomy or radiofrequency cauterization., Methods: In this study, we enrolled 60 patients diagnosed with inferior concha hypertrophy. These patients were divided into two groups by using computer program "Research Randomizer." Of the 60 patients, 30 underwent submucosal inferior turbinoplasty and 30 underwent radiofrequency cauterization. The control group was composed of 30 healthy adults with no nasal or upper aerodigestive system pathology. The patients were checked at weeks 1, 2, and 4. Voice records were taken before the procedure and at week 4 postprocedure., Results: The mean age of patients in the inferior turbinoplasty group was 29.4 years (range: 19-42 years); in the radiofrequency group, it was 30.30 years (range: 18-50 years). There was no statistical difference in age between groups. In the inferior turbinoplasty group, there were 16 male and 14 female patients, and in the radiofrequency group, there were 13 male and 17 female patients. There was no significant difference in the number of males and females between groups., Conclusions: Voice professionals, especially singers, actors, and actresses, should be informed about possible voice changes before undergoing endonasal surgery because these individuals are more sensitive to changes in resonance organs. We believe that voice quality should be regarded as a highly important parameter when measuring the success of endonasal surgery., (Copyright © 2017 The Voice Foundation. Published by Elsevier Inc.

Objective: Atrial fibrillation (AF) is the most common sustained arrhythmia and is associated with increased morbidity and mortality. Atrial fibrosis augments recurrence rate following AF catheter ablation. Osteopontin is a multifunctional molecule involved in several pathophysiological pathways, including fibrosis. Presently described is investigation of relationship between serum osteopontin level and AF recurrence after AF cryoablation., Methods: The study was designed to be prospective and observational; 60 patients with paroxysmal (n=47) and persistent (n=13) AF were included. Osteopontin level was measured both before and 6 months after AF ablation with cryoballoon., Results: Preprocedure and postprocedure osteopontin level did not differ between the 2 groups of AF patients (p=0.286, p=0.493, respectively). Postprocedure osteopontin level was significantly higher compared with preprocedure value (32.18 ng/mL vs 15.58 ng/mL; p=<0.001). Left atrial diameter, AF type, and preprocedure osteopontin level were related to AF recurrence (p≤0.05). An age-adjusted multivariate logistic regression analysis was conducted to determine independent predictors of AF recurrence. Among these, AF type (ß=2.211; p=0.004; odds ratio [OR]: 9.124; 95% confidence interval [CI]: 2.026-41.094) was found to be the most important factor related to AF recurrence. Preprocedure osteopontin level also predicted AF recurrence independently (ß=0.059; p=0.048; OR: 1.061; 95% CI 1.001-1.125)., Conclusion: Study results revealed persistency of AF and high preprocedure osteopontin level independently predicted AF recurrence in patients undergoing cryoballoon AF ablation. Association of a biochemical marker with AF recurrence might be beneficial to selection of appropriate patients for cryoballoon procedure and assessment of long-term procedural success.

Purpose: The rehospitalization rate of preterm infants is between 22 and 52% within the first year after discharge. The purpose of this study was to investigate the rehospitalization of preterm infants within 2 months following discharge, considering the level of risks originating from the infant, parents, and the social factors., Design and Methods: The sample was composed of 238 preterm infants and their parents. The data were collected with a Descriptive Information Form, the Post-Discharge Infant Follow-up Form, and the Neonatal Discharge Assessment Tool (N-DAT). Before discharge, the preterm infants were evaluated in terms of risky discharge via N-DAT consisting of the subscales Medical, Competencies, Risk factors, Resources, and Parenting. Discharge was determined as low, moderate, and high risk according to N-DAT total score. Two months after the discharge, rehospitalization of the infants was assessed. The data were evaluated via chi-square, Mann-Whitney U-test, and Fisher's exact test., Results: In the study, 39.9% of the preterm infants were rehospitalized within the 8 weeks following the discharge, with medical and/or surgical reasons. Medical problems such as pneumonia and acute bronchiolitis were ranked as the first cause for rehospitalization. As expected, according to the N-DAT scores, the rates of rehospitalization of infants who had been discharged with intermediate and high risk levels were found to be higher (p < .001) than the rates of those with low risk levels. Also, N-DAT Medical, Competencies, Risk factors, Resources, and Parenting subscale scores of the infants who were rehospitalized with medical problems were found to be higher at a statistically significant level than infants who were not rehospitalized (p < .001)., Practice Implications: Nurses can help to minimize rehospitalization of infants by parental education, telephonic counseling, frequent observation, and home care support., (© 2016, Wiley Periodicals, Inc.)

Introduction: Epidemiological studies have suggested that patients with psoriasis are at an increased risk of developing cardiovascular diseases. Chronic inflammation may play a role in the pathogenesis of atherosclerosis in psoriasis patients. Recent studies have evaluated the expression of plasma endocan and homocysteine levels. Endocan is a marker of vascular endothelial damage, and homocysteine plays a role in the development of atherosclerosis. Plasma endocan and homocysteine levels, as well as echocardiographic parameters, were evaluated in patients with psoriasis to assess cardiovascular disease risk., Material and Methods: This was a prospective cohort analysis of 40 patients who were diagnosed with psoriasis and 40 healthy controls matched to the patient group according to demographic and biochemical parameters., Results: Serum endocan and homocysteine concentrations were significantly higher in the psoriasis group than the control group ( p < 0.001). Serum endocan concentrations correlated positively with disease duration ( p < 0.001; r = 0.725). The Tei index (myocardial performance) was elevated in psoriasis patients ( p < 0.001). Additionally, the E/A (mitral valve early diastolic peak flow velocity/mitral valve late diastolic peak flow velocity) and E/Em (early diastolic myocardial velocity) ratios were reduced in psoriasis patients ( p < 0.001). Parameters indicative of left ventricular asynchrony were elevated significantly in the psoriasis group versus the control group ( p < 0.001)., Conclusions: We observed a substantial increase in serum endocan and homocysteine concentrations, and significant differences in key parameters of cardiac function, in psoriasis patients relative to controls. These results are consistent with the hypothesis that subclinical cardiac damage is increased in patients with psoriasis and that psoriasis itself may be a cardiovascular risk factor., Competing Interests: The authors declare no conflict of interest.

Objective: Vitamin D deficiency is associated with coronary artery disease, hypertension, heart failure, endothelial dysfunction, and metabolic syndrome. The pathophysiology of cardiac syndrome X (CSX) involves many pathways that are influenced by vitamin D levels. This study aimed to investigate the relationship between vitamin D deficiency and abnormal blood pressure response to exercise in patients with CSX., Methods: This was a cross-sectional and observational study. Fifty females with normal epicardial coronary arteries who presented with typical symptoms of rest or effort angina and 41 healthy age-matched female controls, were included. Patients with cardiomyopathy, severe valvular disease, congenital heart disease, and left ventricular hypertrophy were excluded. All patients underwent stress electrocardiography examination and 25-hydroxy (OH) vitamin D level measurements., Results: Levels of 25-OH vitamin D were significantly lower in CSX patients (9.8±7.3 ng/mL vs. 18.1±7.9 ng/mL; p<0.001). Systolic blood pressure (SBP) (188±15 mm Hg vs. 179±17 mm Hg; p=0.013) and diastolic blood pressure (DBP) (98±9 mm Hg vs. 88±9 mm Hg; p<0.001) during peak exercise were higher in CSX patients. Levels of 25-OH vitamin D were negatively correlated with peak SBP (r=-0.310, p=0.004) and peak DBP (r=-0.535, p<0.001) during exercise. To discard the multicollinearity problem, two different models were used for multivariate analyses. In the first model, metabolic equivalents (METs) (p=0.003) and 25-OH vitamin D levels (p=0.001) were independent predictors. METs (p=0.007), 25-OH vitamin D levels (p=0.008), and peak DBP were determined as independent predictors in the second multivariate model., Conclusion: In patients with CSX, 25-OH vitamin D levels were lower than those in controls; moreover, 25-OH vitamin D deficiency was also associated with higher levels of peak DBP during exercise.

Intracranial metastasis of prostate cancer is rarely seen, and there are few studies in this regard in the literature. Most of these studies in the literature comprise the metastasis of prostate cancer to the sphenoid sinus, and metastasis to the frontal and ethmoid sinus is a much rare entity. Association of visual symptoms, epistaxis, headache, and hematuria may indicate a urologic malignancy in terms of the origin of the primary tumor. This study was aimed to present the prostate cancer case of a 73-year-old patient whose paranasal sinus tomograms revealed the presence of frontal and ethmoid sinus metastasis., Competing Interests: No conflict of interest was declared by the authors.

Background: We intended to study whether there is a meaningful difference in microscopic examination between dividing a biopsy section into two equal parts before tissue processing (first method) or after (second method)., Methods: A total of 400 cases were included in the study. Punch biopsies (PB) were cut into two pieces using the first method in 200 cases and just before paraffin embedding in another 200 cases using the second method. We microscopically evaluated the epidermal mesh view, the presence of a cross-cut hair follicle and bow shape because of epidermal angling, the presence of two pieces on the slide and if there was a difference of >2 mm between the parts, and the number of new sections and new slides., Results: Cross-cut hair follicle (p = 0.018), epidermal mesh view (p = 0.036), difference of >2 mm between the parts (p = 0.008), the number of new sections (p < 0.001) and new slides (p < 0.001) were considerably higher when the first method was used compared with the second method. The presence of two pieces was less (p < 0.001) when using the first method., Conclusions: We noted a meaningful difference in the quality of microscopic evaluation between the first and second methods. Better sections were obtained with the second method. In addition, the decrease in the number of new slides will reduce workload, archival work and cost., (© 2016 John Wiley & Sons A/S.

Nasopharyngeal carcinoma (NPC) is associated with the Epstein-Barr virus (EBV). Human papilloma virus (HPV) has also been detected in NPC cases. In this retrospective study, we analyze the frequency of EBV and HPV infection in 82 Turkish patients with NPC. A total of 82 were evaluated for EBV and HPV. In situ hybridization (ISH) was performed for EBV. HPV-ISH and P16 immunohistochemistry used to determine the HPV status. Seventy-two of the 82 (87%) NPC patients were EBV-positive. The highest rate of EBV-positivity was found in undifferentiated NPC patients, which accounted for 65 of 68 (95.6%) undifferentiated cases. One of the 82 NPC patients whose tumor was non-keratinizing differentiated, contained HPV. Our data shows that EBV is closely associated with NPC in Turkey. We found lower rates of HPV-positivity in NPC patients than in North American populations. In addition, both EBV and HPV-negativity were more associated with decreased survival than EBV-positive cases., (Copyright © 2016 Elsevier GmbH. All rights reserved.)

Objective: Atrial fibrillation (AF) is the most common arrhythmia following coronary artery by-pass graft surgery (CABG). The value of SYNTAX score to predict postoperative atrial fibrillation (PoAF) has not been clearly addressed. We aimed to evaluate this relationship in patients undergoing isolated CABG., Methods: This study was designed as a single-center, non-randomized, observational, prospective study. Ninety-four patients undergoing isolated on-pump CABG, who had sinus rhythm and were older than 18 years, were enrolled. Demographic characteristics of the patients were recorded; SYNTAX score was calculated preoperatively for each patient. The univariate and multivariate logistic regression analysis were used to determine for predictors of PoAF., Results: The median SYNTAX score of the enrolled patients was 21, (56-5). PoAF was observed in 31 (33.3%) patients. Univariate logistic regression showed that age, chronic obstructive pulmonary disease (COPD), red blood cell distribution width (RDW), urea, initial troponin I, peak postoperative troponin I, interventricular septum, left atrial diameter, and SYNTAX score were significantly associated with the frequency of PoAF following CABG. An independent association was identified with age [ß: 0.088, p:0.023, OR: 1.092, 95% CI (1.012-1.179)], COPD [(ß: 2.222, p:0.003, OR: 9.228, 95% CI (2.150-39.602)], and SYNTAX score [(ß: 0.130, p:0.002, OR: 1.139, 95% CI (1.050-1.235)]., Conclusion: This study showed that a higher SYNTAX score was related to more frequent PoAF in patients undergoing isolated on-pump CABG.

Adverse health effects of radiofrequency radiation (RFR) on the ongoing developmental stages of children from conception to childhood are scientifically anticipated subject. This study was performed to identify the effects of global system for mobile communications (GSM) modulated mobile phone like RFR in 1800MHz frequency on oxidative DNA damage and lipid peroxidation beside the apoptotic cell formation, using histopathological and immunohistochemical methods in the brain tissue of 1-month-old male and female New Zealand White rabbits that were exposed to these fields at their mother's womb and after the birth. Oxidative DNA damage and lipid peroxidation levels were investigated by measuring the 8-hydroxy-2'-deoxyguanosine (8-OHdG) and malondialdehyde (MDA) levels, respectively. Histopathological changes were observed using by hematoxylin and eosin (HE) staining. Apoptotic cells were detected in the examined organs by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) staining. For both male and female infants; 8-OHdG levels increased in the group exposed to RFR in both intrauterine and extrauterine periods compared to the infants that were never exposed to RFR and the ones were exposed when they reached one month of age (p<0.05). MDA results were different for male and female rabbits. There was no difference between all female infant groups (p>0.05), while only intrauterine exposure significantly causes MDA level increase for the male infants. HE staining revealed mild lessions in neuronal necrobiosis in brain tissues of female rabbits that had only intaruterine exposure and male rabbits had only extrauterine exposure. Gliosis were mildly positive in brain tissues of rabbits that are exposed only intrauterine period, also the group exposed both intrauterine and extrauterine periods. However, there was no apoptotic change detected by TUNEL staining in the brain tissues of all groups., (Copyright © 2015 Elsevier B.V. All rights reserved.)

Objectives: To evaluate the efficacy of trimetazidine dihydrochloride as a treatment for chronic tinnitus., Methods: A total of 97 chronic tinnitus patients were evaluated in this randomized, prospective, double-blind, placebo-controlled trial. After assessing for eligibility, 82 patients were randomly assigned into placebo or trimetazidine groups according to the medication. The trimetazidine group received 20×3 mg/day per oral trimetazidine dihydrochloride and the placebo group received 20×3 mg/day per oral placebo for 3 months. Tinnitus handicap inventory (THI), visual analogue scale (VAS) questionnaires and audiometric results were used to determine the effectiveness of trimetazidine treatment., Results: The study group comprised 82 tinnitus subjects, 42 (51%) of whom received trimetazidine dihydrochloride and 40 (49%) who received placebo. There was no significant difference between placebo and trimetazidine groups in THI grade and VAS (both pre- and posttreatment scores) (P>0.05) and no significant improvement was observed in subjective loudness score in either group (P>0.05). Additionally there was no significant difference between groups in pre- and posttreatment pure tone hearing thresholds at all measured frequencies (P>0.05)., Conclusion: Trimetazidine dihydrochloride therapy was ineffective for relieving chronic tinnitus., Competing Interests: No potential conflict of interest relevant to this article was reported.

Tumor cells develop drug resistance which leads to recurrence and distant metastasis. MicroRNAs are key regulators of tumor pathogenesis; however, little is known whether they can sensitize cells and block metastasis simultaneously. Here, we report miR-644a as a novel inhibitor of both cell survival and EMT whereby acting as pleiotropic therapy-sensitizer in breast cancer. We showed that both miR-644a expression and its gene signature are associated with tumor progression and distant metastasis-free survival. Mechanistically, miR-644a directly targets the transcriptional co-repressor C-Terminal Binding Protein 1 (CTBP1) whose knock-outs by the CRISPR-Cas9 system inhibit tumor growth, metastasis, and drug resistance, mimicking the phenotypes induced by miR-644a. Furthermore, downregulation of CTBP1 by miR-644a upregulates wild type- or mutant-p53 which acts as a 'molecular switch' between G1-arrest and apoptosis by inducing cyclin-dependent kinase inhibitor 1 (p21, CDKN1A, CIP1) or pro-apoptotic phorbol-12-myristate-13-acetate-induced protein 1 (Noxa, PMAIP1), respectively. Interestingly, an increase in mutant-p53 by either overexpression of miR-644a or downregulation of CTBP1 was enough to shift this balance in favor of apoptosis through upregulation of Noxa. Notably, p53-mutant patients, but not p53-wild type ones, with high CTBP1 have a shorter survival suggesting that CTBP1 could be a potential prognostic factor for breast cancer patients with p53 mutations. Overall, re-activation of the miR-644a/CTBP1/p53 axis may represent a new strategy for overcoming both therapy resistance and metastasis., Competing Interests: The authors declare that they have no conflicts of interest.

We conducted a cross-sectional study to assess vocal and swallowing functions after horizontal glottectomy. Our study population was made up of 22 men aged 45 to 72 years (mean: 58.3) who underwent horizontal glottectomy and completed at least 1 year of follow-up. To compare postoperative results, 20 similarly aged men were included as a control group; all glottectomy patients and all controls were smokers. We used three methods-acoustic and aerodynamic voice analyses, the GRBAS (grade, roughness, breathiness, asthenicity, and strain) scale, and the voice handicap index-30 (VHI-30)-to assess vocal function objectively, perceptually, and subjectively, respectively. We also assessed swallowing function objectively by fiberoptic endoscopic evaluation of swallowing (FEES) and subjectively with the M.D. Anderson dysphagia inventory (MDADI). The 22 patients were also subcategorized into three groups according to the extent of their arytenoid cartilage resection, and their outcomes were compared. Acoustic and aerodynamic analyses showed that the mean maximum phonation time was significantly shorter and the fundamental frequency was significantly lower in the glottectomy group than in the controls (p = 0.001 for both), and that the mean jitter and shimmer values and the mean harmonics-to-noise ratio were all significantly higher (p = 0.001 for all); there were no significant differences among the three arytenoid subgroups. Self-assessments revealed that there were no statistically significant differences among the three subgroups in GRBAS scale scores except for the breathiness score (p = 0.045), which was lower in the arytenoid preservation subgroup than in the total resection subgroup; there were no statistically significant differences among the three subgroups in VHI-30 scores. Finally, swallow testing found no statistically significant differences in FEES scores or MDADI scores. We conclude that horizontal glottectomy caused a deterioration in vocal function, but swallowing function was satisfactory.

Nitrite salts of sodium or potassium are being used for the protection of meat products. They provide color and taste of meat and they protect against clostridia. On the other hand, nitrite ions can interact with amines to form nitrosamines which are known as carcinogenic substances. They may also react with hemoglobin and reduce its oxygen carrying capacity. Thus, its concentration in food-stuff has to be controlled carefully by highly sensitive methods. A new DP polarographic method is established for the determination of nitrite. Nitrite cannot be determined directly with any analytical methods. Long and tedious procedures are necessary for many of them. In this polarographic method arsenite, As(III), ion is used for the reduction of nitrite. The nitrite is determined from the As(III) quantity left over after the reaction with nitrite. The peak of arsenite has been used since it is sharp and responds well for the standard addition of arsenite. The optimum conditions for the quantitative reaction between nitrite and arsenite have been studied. It was found that the pH for the reaction medium has to be 5-7, since nitrite is decomposed at lower pH values. The reaction medium has to be stirred for about 5 min with nitrogen gas in order to expel the NO gas formed and thus to shift the equilibrium to products side. The limit of detection, LOD, was found to be as 2 × 10(-7) M. No interference was observed from most common ions., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Purpose: Systolic alterations in left ventricular (LV) myocardial function have been reported previously in patients with diastolic dysfunction (DD). Recent advances in real-time three-dimensional echocardiography (3DE) enable the measurement of a set of parameters previously difficult to obtain with standard two-dimensional echocardiography (2DE). The aim of this study was to evaluate global 3DE LV contraction in patients with and without DD who had normal ejection fraction (EF)., Methods: Sixty-five patients (average age 56 ± 6 years; 31 females and 34 males) with normal EF (>50 %) referred to echocardiographic examination for the evaluation of DD were included. In addition to measuring conventional echocardiographic parameters, they were also evaluated with 3DE. End diastolic volume, end systolic volume, EF, corrected standard deviation (SD) of time to minimal systolic volume for 16 segments its dispersion, average excursion of the segments and the SD of segmental motion (excursion-SD) were recorded., Results: When we tested the differences among three groups of diastolic function (normal, Grade 1, and Grade 2), the results showed that coronary artery disease, left atrial volume, septum, posterior wall, E, A, E/A, deceleration time, E' septum, E' lateral, and excursion-SD were significantly different. An ordered logistic regression analysis revealed that excursion-SD (p < 0.001) and septum (p < 0.001) measurements were statistically significant for predicting DD grade., Conclusion: In our patient population, a decline in excursion-SD values was observed with increasing DD grade. In other words, the amount of segmental difference in terms of excursion was reduced.

Objective: The aim of this study was to analyze the influence of deviated nasal septum (DNS) type on nasal mucociliary clearance, quality of life (QoL), olfactory function, and efficiency of nasal surgery (septoplasty with or without inferior turbinate reduction and partial middle turbinectomy)., Methods: Fifty patients (20 females and 30 males) with septal deviation were included in the study and were divided into 6 groups according to deviation type after examination by nasal endoscopy and paranasal computed tomography. The saccharin clearance test to evaluate the nasal mucociliary clearance time, Connecticut Chemosensory Clinical Research Center smell test for olfactory function, and sinonasal outcome test-22 (SNOT-22) for patient satisfaction were applied preoperatively and postoperatively at the sixth week after surgery., Result: Nasal mucociliary clearance, smell, and SNOT-22 scores were measured before surgery and at the sixth week following surgery. No significant difference was found in olfactory and SNOT-22 scores for any of the DNS types (both convex and concave sides) (P > 0.05). In addition, there was no difference in the saccharin clearance time (SCT) of the concave and convex sides (P > 0.05). According to the DNS type, the mean SCT of the convex sides showed no difference, but that of the concave sides showed a difference in types 3, 4, 5, and 6. These types had a prolonged SCT (P < 0.05). Olfactory scores revealed no difference postoperatively in types 5 and 6 but were decreased significantly in types 1 to 4 (P < 0.05). There was no significant difference in the healing of both the mucociliary clearance (MCC) and olfactory functions. SNOT-22 results showed a significant decrease in type 3., Conclusion: All DNS types disturb the QoL regarding nasal MCC and olfaction functions. MCC values, olfactory function, and QoL scores are similar among the DNS types. Both sides of the DNS types affect the MCC scores symmetrically. Septal surgery improves olfaction function and QoL at the sixth week following surgery but disturbs nasal MCC; thus, the sixth week is too early to assess nasal MCC.

Objective: In the current study, we aimed to explore whether there is alteration between pre- and post-treatment micronucleus (MN) frequencies induced by internal and external ionizing radiation., Materials and Methods: The study enrolled a total of 67 patients including patients admitted to our hospital for treatment of hyperthyroidism (n = 17), scanning with low-dose I-131 (n = 15), and ablative therapy with high-dose I-131 (n = 15) at Department of Nuclear Medicine as well as patients with different diagnoses receiving external radiotherapy with various doses and durations at Department of Radiation Oncology (n = 20). Thirty-two patients who received radioactive iodine and returned for a follow-up visit at 1 month., Results: Considering both pre- and post-treatment MN frequencies of each group, lowest MN frequencies were detected for patients undergoing screening with low-dose I-131, and highest MN frequencies were found in radiotherapy patients. Comparison of pre- and post-treatment MN frequencies among hyperthyroidism, when pre- and post-treatment MN frequencies compared among hyperthyroidism, I-131 whole body scanning, ablation, and radiotherapy patient groups differences between MN frequencies were significant for each group (P < 0.05)., Conclusion: Our study showed that MN analysis might be of value in determining chromosome damage that could potentially occur in patients exposed to internal and external radiation.

Takotsubo cardiomyopathy (TTC), also known as left ventricular apical ballooning syndrome or stress cardiomyopathy, is characterized by transient left ventricular systolic dysfunction and the absence of obstructive lesion in the epicardial coronary arteries. The most common presentation is acute substernal chest pain, although occasionally dyspnea and syncope, and rarely shock with ST-segment elevation and elevated cardiac biomarkers have been observed. Inverted (reverse) TTC is a rare pattern characterized hypokinesis of the basal and midventricular segments. Presently described was case of a 27-year-old woman with ventricular fibrillation following endoscopic nasal sinus surgery.

Entering college with posttraumatic stress disorder (PTSD) symptomatology has been linked to poor academic performance and increased risk for dropping out of college; however, little is known regarding the mechanisms by which PTSD symptoms have deleterious effects on college outcomes. Drawing from a self-regulated learning (SRL) perspective, which suggests that students' learning behaviors and outcomes can be influenced by contextual and developmental factors, we hypothesized that students who enter college with high PTSD symptomatology may experience difficulties in effort regulation, which in turn, may have deleterious effects on their academic performance and college persistence. These hypothesized relationships, as well as the potential gender differences in these relationships were examined using a longitudinal study design and a multigroup structural equation modeling approach. Of the 928 1st-year students who participated in the study, 484 (52.2%) students who reported lifetime exposure to traumatic events constituted the final sample of the study. The prevalence of PTSD among the trauma-exposed participants was 12.4%. After controlling for participation in on-campus activities and American College Testing (ACT) assessment scores, the relationship between PTSD symptomatology in the 1st semester of college and 2nd-year enrollment was mediated by effort regulation and 1st-year cumulative grade-point average (GPA). Specifically, participants who started college with higher levels of PTSD symptomatology also reported lower levels of effort regulation, which in turn, had a significant indirect effect on 2nd-year enrollment through 1st-year GPA. Results also indicated that the paths in the hypothesized model were not significantly different for men and women. (PsycINFO Database Record, ((c) 2016 APA, all rights reserved).)

Introduction: Slow coronary flow (SCF) is an angiographic phenomenon characterized by delayed opacification of epicardial coronary arteries without an obstructive coronary disease. Serum soluble urokinase-type plasminogen activator receptor (suPAR) levels seem closely related to atherosclerosis due to increased inflammation and prothrombotic state. We studied whether circulating suPAR is related to SCF., Material and Methods: The present study was cross-sectional and observational. It included 75 individuals who underwent coronary angiography with suspected CAD and had angiographically normal coronary arteries of varying coronary flow rates. The relationship between suPAR, C-reactive protein (CRP) and SCF was investigated. Forty patients with isolated SCF (mean age: 46.0 ±4.14 years) and 35 age- and gender-matched control participants with normal coronary flow (NCF) and normal coronary arteries (NCA) (mean age: 46.0 ±5.7 years) were included in the study. We used logistic regression analysis to determine the predictors of SCF., Results: The clinical characteristics were not statistically significantly different between SCF and NCA groups. Serum suPAR level was significantly higher in the SCF group than the control group (2.5-5.4 ng/ml vs. 0.1-1.4 ng/ml; p < 0.001). Also the serum CRP level was higher in the CSF group than the control group (1.57 ±0.43 mg/l vs. 0.53 ±0.23 mg/l; p < 0.001)., Conclusions: This study revealed significantly increased serum suPAR levels in patients with SCF. Although we cannot draw conclusions on the underlying pathological process of SCF, we believe that these findings may be pioneering for further studies investigating the specific roles of circulating suPAR in the SCF phenomenon in the coronary vasculature., Competing Interests: The authors declare no conflict of interest.

BRAF(V600E) mutation was analyzed by real-time polymerase chain reaction in 96 consecutive cases with classical variant papillary thyroid cancer, and immunohistochemical staining of Na+/I- symporter (NIS) protein was evaluated. Localization (intracellular or membranous), density, and the intensity of cytoplasmic staining were characterized semiquantitatively. Extrathyroidal invasion, surgical margin positivity, and lymph node metastasis were compared with BRAF(V600E) mutation and NIS expression. Eighty-eight patients who had at least 24-month follow-up were also included in survival analysis. BRAF(V600E) mutation was determined in 78.1% (75/96) and functional NIS activity in 74% (71/96) of the cases. There were statistically significant differences in mean ages between BRAF(V600E) mutation-positive (48.6) and BRAF(V600E) mutation-negative cases (37.3; Levene test, P=.419; Student t test, P=.001). The surgical margin positivity (46.7%) and extrathyroidal extension percentage (54.7%) in the BRAF(V600E) mutation-positive group were higher than the negative (28.6% and 33.3%, respectively) group, without statistical significance (P=.138 and P=.084, respectively). Functional NIS activity was higher in BRAF(V600E) mutation-positive cases (78.1%) than mutation-negative ones (57.1%; P=.047). The possibility of moderate and intense cytoplasmic staining in BRAF(V600E) mutation-positive cases (72%) was 6.3 times higher than the possibility of weak staining (28%) in the mutation-positive cases (95% confidence interval, 2.2-18.8; P=.001). Functional NIS expression is higher in patients with classical variant papillary thyroid cancer with BRAF(V600E) mutation. However, the clinical features were not found to be associated with NIS expression. There may be different mechanisms determining the outcome of therapy., (Copyright © 2016 Elsevier Inc.

Enzymatically-induced degradation of bovine serum albumin (BSA) by serine proteases (trypsin and α-chymotrypsin) in various concentrations was monitored by means of Fourier transform infrared (FT-IR) and ultraviolet circular dichroism (UV-CD) spectroscopy. In this study, the applicability of both spectroscopies to monitor the proteolysis process in real time has been proven, by tracking the spectral changes together with secondary structure analysis of BSA as proteolysis proceeds. On the basis of the FTIR spectra and the changes in the amide I band region, we suggest the progression of proteolysis process via conversion of α-helices (1654 cm(-1)) into unordered structures and an increase in the concentration of free carboxylates (absorption of 1593 and 1402 cm(-1)). For the first time, the correlation between the degree of hydrolysis and the concentration of carboxylic groups measured by FTIR spectroscopy was revealed as well. The far UV-CD spectra together with their secondary structure analysis suggest that the α-helical content decreases concomitant with an increase in the unordered structure. Both spectroscopic techniques also demonstrate that there are similar but less spectral changes of BSA for the trypsin attack than for α-chymotrypsin although the substrate/enzyme ratio is taken the same., (Copyright © 2016 Elsevier B.V.

Acinetobacter baumannii is an opportunistic pathogen which is one of the most important agents of nosocomial infections. Being resistant to many antibiotics, complicates the treatment of the infections caused. Fluoroquinolones are used in the treatment of nosocomial and community-acquired infections and it is important to determine the mechanisms of resistance to these antibiotics. The aims of this study were to investigate ciprofloxacin (CIP) and levofloxacin (LEV) minimum inhibitor concentrations (MIC), clonal relationships, mutations that occur in DNA gyrase and topoisomerase IV genes and overexpression of efflux pumps in nosocomial A.baumannii isolates. A total of 81 A.baumannii strains, 79 CIP-resistant and two CIP-susceptible, isolated from different clinical samples in Ege University Faculty of Medicine, Department of Medical Microbiology were included in the study. CIP and LEV MIC values were determined by broth microdilution method. Clonal relationship among the strains was investigated by ERIC-PCR (Enterobacterial repetitive intergenic consensus-polymerase chain reaction). Mutations that occur in gyrA and parC genes were detected by DNA sequence analysis in 16 strains representing each clone and subtype. Overexpression of the efflux pumps was evaluated by broth microdilution and fluorometric accumulation experiments were carried out in the presence of pump inhibitors, among the representative strains. MIC(50) and MIC(90) values for CIP were 256 µg/ml and ≥ 256 µg/ml, while the values were 32 µg/ml and 128 µg/ml for LEV, respectively. Overall, CIP MIC values were found to be higher than that of LEV among the A.baumannii strains studied. Isolates were grouped into six main groups and 10 different clusters (39 strains in cluster A, 20 in B, 13 in C, two of each in I and J, one of each in D-H clusters), but it was observed that the majority of them were clonally related. The most common and important mutations detected in the gyrA and parC genes of the representative isolates were, Ser83Leu, Asp87Glu and Ser80Leu, respectively. While the overexpression of efflux pumps was observed in seven of the representative strains by microdilution method, in 11 by fluorometric assay and the results were positive in five of the strains by both methods. CIP was found to be better than LEV for detecting the overexpression of pumps by the use of microdilution method. It was concluded that, the reason of high fluoroquinolone MIC values of the studied nosocomial and clonally related A.baumannii strains were related to target mutations and overexpression of efflux pumps besides the plasmid-mediated mechanisms, such as Qnr might also have played a role.

Objective: The aim of this study was to investigate whether there is an effect of trifluoperazine on Tc-99m  methoxyisobutylisonitrile (MIBI) uptake in patients with advanced nonsmall cell lung cancer (NCLC)., Materials and Methods: A total of 23 patients with biopsy-proven advanced NCLC who had no previous history of chemo-radiotherapy, underwent baseline dual phase planar, single photon emission computed tomography and whole body Tc-99m MIBI scintigraphy performed at 20 and 120 min. After oral administration of trifluoperazine (5 mg, 2 times a day, for 5 days), dual phase Tc-99m MIBI scintigraphy was repeated. For each patient, and for both studies, regions of interest were drawn over the tumor area (T) and over the normal lung area (L) on the contralateral side in transverse slices where tumor was visualized clearly. Then, early and delayed T/L ratios and washout rate (WR) were calculated., Results: Tc-99m MIBI was accumulated in the cancer tissue in all of the patients. Delayed ratio after the oral administration of trifluoperazine (DR2) was significantly higher (P = 0.039) than delayed ratio before trifluoperazine (DR1). We found no significant differences of early ratio before trifluoperazine (ER1) and early ratio after trifluoperazine (ER2), and washout rate before (WR1) and washout rate after trifluoperazine (WR2)., Conclusion: In patients with advanced NCLC, trifluoperazine treatment in addition to chemotherapy might be useful. However, our results need to be confirmed in larger series of patients.

Purpose: To investigate the reliability and validity of the Neonatal Discharge Assessment Tool (N-DAT) designed to assess risk factors related to infants' and parents' readiness for discharge to home., Design and Methods: The sample was composed of 238 high-risk preterm infants, born at gestational age of 24 to 37 weeks, and their parents. High scores on the N-DAT indicated higher risk for discharge of preterm infants and their parents. Psychometric analyses of the N-DAT included content validity, internal consistency reliability, and construct validity., Results: Content validity of the N-DAT items was supported by experts (content validity index = .98). Internal consistency reliability was supported by a Cronbach's alpha for the total instrument of .94. N-DAT total and subscale score correlations ranged from .42 to .89. Known-groups analysis indicated that infants born at <31 weeks' gestation and infants who were rehospitalized during 8 weeks after discharge had significantly higher N-DAT total and subscale scores than infants born at ≥31 weeks or not rehospitalized. Also, mothers who reported experiencing problems with infant care at home had significantly higher N-DAT Competencies subscale scores than mothers who did not report problems., Practice Implications: The N-DAT is a reliable and valid instrument to evaluate the risks related to discharge of preterm infants so that nurses can provide parents with the necessary knowledge, skills, and resources they need prior to discharge., (© 2016, Wiley Periodicals, Inc.)

The Na(+)-coupled betaine symporter BetP senses changes in the membrane state and increasing levels of cytoplasmic K(+) during hyperosmotic stress latter via its C-terminal domain and regulates transport activity according to both stimuli. This intriguing sensing and regulation behavior of BetP was intensively studied in the past. It was shown by several biochemical studies that activation and regulation depends crucially on the lipid composition of the surrounding membrane. In fact, BetP is active and regulated only when negatively charged lipids are present. Recent structural studies have revealed binding of phosphatidylglycerol lipids to functional important parts of BetP, suggesting a functional role of lipid interactions. However, a regulatory role of lipid interactions could only be speculated from the snapshot provided by the crystal structure. Here, we investigate the nature of lipid-protein interactions of BetP reconstituted in closely packed two-dimensional crystals of negatively charged lipids and probed at the molecular level with Fourier transform infrared (FTIR) spectroscopy. The FTIR data indicate that K(+) binding weakens the interaction of BetP especially with the anionic lipid head groups. We suggest a regulation mechanism in which lipid-protein interactions, especially with the C-terminal domain and the functional important gating helices transmembrane helice 3 (TMH3) and TMH12, confine BetP to its down-regulated transport state. As BetP is also activated by changes in the physical state of the membrane, our results point toward a more general mechanism of how active transport can be modified by dynamic lipid-protein interactions., (© 2016 by The American Society for Biochemistry and Molecular Biology, Inc.)

Introduction: Extremely high glucose concentrations have been shown to interfere with creatinine assays especially with Jaffe method in peritoneal dialysate. Because diabetes is the fastest growing chronic disease in the world, laboratories study with varying glucose concentrations. We investigated whether different levels of glucose spiked in serum interfere with 21 routine chemistry and thyroid assays at glucose concentrations between 17-51 mmol/L., Materials and Methods: Baseline (group I) serum pool with glucose concentration of 5.55 (5.44-5.61) mmol/L was prepared from patient sera. Spiking with 20% dextrose solution, sample groups were obtained with glucose concentrations: 17.09, 34.52, and 50.95 mmol/L (group II, III, IV, respectively). Total of 21 biochemistry analytes and thyroid tests were studied on Abbott c8000 and i2000sr with commercial reagents. Bias from baseline value was checked statistically and clinically., Results: Creatinine increased significantly by 8.74%, 31.66%, 55.31% at groups II, III, IV, respectively with P values of < 0.001. At the median glucose concentration of 50.95 mmol/L, calcium, albumin, chloride and FT4 biased significantly clinically (-0.85%, 1.63%, 0.65%, 7.4% with P values 0.138, 0.214, 0.004, < 0.001, respectively). Remaining assays were free of interference., Conclusion: Among the numerous biochemical parameters studied, only a few parameters are affected by dramatically increased glucose concentration. The creatinine measurements obtained in human sera with the Jaffe alkaline method at high glucose concentrations should be interpreted with caution. Other tests that were affected with extremely high glucose concentrations were calcium, albumin, chloride and FT4, hence results should be taken into consideration in patients with poor diabetic control.

The purpose of this study was, conducted with experimental design, to investigate the effect of reminiscence therapy on cognition, depression, activities of daily living of institutionalized mild and moderate Alzheimer patients. The study was conducted with a total of 62 patients (31 intervention group and 31 control group) in four home care in Ankara, Turkey. Study was done between the July 1, 2013 and December 20, 2014. Reminiscence therapy sessions were held with groups consists of 4-5 patients, once a week with 30-35 minute duration for 12 weeks. Standardized Mini Mental Test was used in sample selection. Patients were listed through their mini mental test scores, and randomized as odd numbers to control group and even numbers to intervention group. Data were collected with forms developed by researcher 'Data Sheet' and 'Activities of Daily Living Follow-up Form' as well as scales 'Standardized Mini Mental Test' and 'Geriatric Depression Scale'. Chi-square, Mann Whitney-U test, variance analyses in repeated measures and Bonferroni tests were used for analysis. The increase in mean Standardized Mini Mental Test score and the decrease in mean Geriatric Depression Scale score of the individuals in the intervention group compared to the control group at the end of the reminiscence therapy was statistically significant (P < 0.05). At the end of reminiscence therapy sessions, increase in cognition and decrease in depression were found statistically significant in intervention group., (© The Author(s) 2015.)

The purpose of this study was to examine the relationship between depressive symptomatology and college outcomes among African American students, as well as to determine whether these relationships were moderated by gender and type of university. Participants included 569 African American first-year students attending two public universities in the Southeast United States: a historically Black college/university (HBCU) and a predominantly White institution (PWI). Using a longitudinal study design, data were collected at three time points. Results indicated that, after adjusting for the effects of the control variables (gender, type of institution, high school GPA, participation in on-campus activities, institutional and goal commitments), depressive symptomatology present in the first semester of college was associated with increased likelihood of dropping out of college before the end of the second year of college. The relationship between these two variables was mediated by first-year cumulative GPA. Results also indicated that the hypothesized relationships did not vary as a function of gender and the university type.

Objective: This study aimed to evaluate vocal changes in pregnancy according to trimesters both objectively and subjectively., Methods: Fifty pregnant women and 15 nonpregnant women were included in the study. Eighteen of the 50 pregnant women were in the first trimester, 17 in the second trimester, and 15 in the third trimester of their pregnancies. The fundamental frequency (F0), jitter, shimmer, noise-to-harmonics ratio (NHR), and minimum and maximum pitch were determined during acoustic voice analysis. Laryngologic examination was evaluated via reflux finding score (RFS). Voice Handicap Index 10 (VHI-10) was used for subjective analysis., Results: Maximum phonation time (MPT), VHI-10, and RFS were the parameters that differed significantly. MPT was significantly shorter in the third trimester. Acoustic analysis revealed that F0, jitter, shimmer, NHR, and minimum and maximum pitch values were not significantly different in any groups. RFS was higher in the first and third trimesters than the second trimester and control groups. VHI-10 scores were significantly higher in the third trimester., Conclusions: Our results showed that MPT is decreased during the third trimester, although acoustic parameters did not differ. VHI-10 results deteriorated in the third trimester significantly., (Copyright © 2016 The Voice Foundation. Published by Elsevier Inc. All rights reserved.)

The aim of this randomized controlled single-blind study is to explore whether addition of mud-pack and hot pool treatments to patient education make a significant difference in short and mild term outcomes of the patients with fibromyalgia. Seventy women with fibromyalgia syndrome were randomly assigned to either balneotherapy with mud-pack and hot pool treatments (35) or control (35) groups. After randomization, five patients from balneotherapy group and five patients from control group were dropped out from the study with different excuses. All patients had 6-h patient education programme about fibromyalgia syndrome and were given a home exercise programme. The patients in balneotherapy group had heated pool treatment at 38 °C for 20 min a day, and mud-pack treatment afterwards on back region at 45 °C. Balneotherapy was applied on weekdays for 2 weeks. All patients continued to take their medical treatment. An investigator who was blinded to the intervention assessed all the patients before and after the treatment, at the first and the third months of follow-up. Outcome measures were FIQ, BDI and both patient's and physician's global assessments. Balneotherapy group was significantly better than control group at after the treatment and at the end of the first month follow-up assessments in terms of patient's and physician's global assessment, total FIQ score, and pain intensity, fatigue, non-refreshed awaking, stiffness, anxiety and depression subscales of FIQ. No significant difference was found between the groups in terms of BDI scores. It is concluded that patient education combined with 2 weeks balneotherapy application has more beneficial effects in patients with fibromyalgia syndrome as compared to patient education alone.

Senescent cells secrete several molecules that help to prevent the progression of cancer. However, cancer cells can also misuse these secreted elements to survive and grow. Since the molecular and functional bases of these different elements remain poorly understood, we analyzed the effect of senescent mesenchymal stromal cell (MSC) secretome on the biology of ARH-77 myeloma cells. In addition to differentiating in mesodermal derivatives, MSCs have sustained interest among researchers by supporting hematopoiesis, contributing to tissue homeostasis, and modulating inflammatory response, all activities accomplished primarily by the secretion of cytokines and growth factors. Moreover, senescence profoundly affects the composition of MSC secretome. In this study, we induced MSC senescence by oxidative stress, DNA damage, and replicative exhaustion. While the first two are considered to induce acute senescence, extensive proliferation triggers replicative (i.e., chronic) senescence. We cultivated cancer cells in the presence of acute and chronic senescent MSC-conditioned media and evaluated their proliferation, DNA damage, apoptosis, and senescence. Our findings revealed that senescent secretomes induced apoptosis or senescence, if not both, to different extents. This anti-tumor activity became heavily impaired when secretomes were collected from senescent cells previously in contact (i.e., primed) with cancer cells. Our analysis of senescent MSC secretomes with LC-MS/MS followed by Gene Ontology classification further indicated that priming with cancer profoundly affected secretome composition by abrogating the production of pro-senescent and apoptotic factors. We thus showed for the first time that compared with cancer-primed MSCs, naïve senescent MSCs can exert different effects on tumor progression.

Objectives: Intimate partner violence (IPV) is an important public health problem in many countries including Turkey, with serious short- and long-term physical and mental health consequences, as well as significant social and public health costs. To understand the violence characteristics and the individual risk factors for both the married women victims and the perpetrator partners are the objectives of this study., Methodology: 243 married women, who have consulted to hospitals and village clinics between 2008 and 2009 with the mean age of 36.76 (SD = 11.59), accepted to participate in the study voluntarily. Participants were divided into two groups as "victimized" (58.8%, n = 143) and "non-victimized" (41.2%, n = 100) women. Victimized group consisted of women who have had any type of violence from their husbands during their life. A 61-item questionnaire was prepared that included items on demographics, IPV experience, attitudes about IPV and knowledge of legal rights., Results: As compared to non-victimized group, women in victimized group mostly lived in villages than in town/city centers, were illiterate, had bride-price agreement and were younger when married. Place of accommodation, age and number of pregnancies were associated with the risk of victimization., Conclusions: In order to prevent IPV, further qualitative research is required to evaluate the involved risk factors and training programs on how to behave against violence in association with the legal rights should be designed for poorly educated women in their natural settings and hospitals., (Copyright © 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Objectives: To determine the effects of an asthma training and monitoring program on children's disease management and quality of life., Material and Methods: The sample consisted of 120 children and their parents. Data were collected during, at the beginning, and at the end of the 3-month monitoring period using four forms and a quality of life scale. After an initial evaluation, approaches to control symptoms and asthma triggers and measures that might be taken for them were taught to the children and parents. The children recorded the conditions of trigger exposure, experience of disease symptoms, their effects on daily activities, and therapeutic implementations on a daily basis., Results: During the 3-month monitoring period, the number of days when the children were exposed to triggers (p=0.000) and experienced disease symptoms decreased to a statistically significant level (p=0.006). Majority of domestic triggers disappeared, but those stemming from the structure of the house and non-domestic triggers indicated no change (p>0.05). Moreover, 30.8% of the children applied to a physician/hospital/emergency service, 4.2% of the children were hospitalized, and 30% of them could not go to school. The number of times when the children applied to a physician/hospital/emergency (p=0.013), the number of times they used medicines (p=0.050), and the number of days they could not go to school (p=0.002) decreased at a statistically significant level, and their quality of life increased (p=0.001)., Conclusion: Asthma training and monitoring program decreased children's rate of experiencing asthma symptoms and implementations of therapeutic purposes and increased their life quality., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Aims: Estimation of left ventricular (LV) filling pressures is a clinical challenge in patients with preserved ejection fraction (EF). In the present study, we investigated whether LV and atrial longitudinal strain and strain rate (SR) parameters derived by speckle tracking echocardiography (STE) could be used to predict invasively measured LV end-diastolic pressure (LVEDP) in this patient population., Methods and Results: LVEDP was measured before coronary angiography was performed in 65 patients with preserved EF (≥50%) referred to elective cardiac catheterization; besides, patients enrolled underwent comprehensive echocardiographic examination before the procedure. In addition to conventional echocardiographic parameters used to evaluate diastolic function LV longitudinal strain and SR, as well as peak atrial longitudinal strain during LV systole, measurements were performed using STE. Only log-diastolic blood pressure, systolic SR, early diastolic SR, SR during isovolumetric relaxation (SRIVR), and mitral early diastolic flow velocity/SRIVR significantly correlated with LVEDP. When age-adjusted stepwise linear regression analysis was performed, SRIVRT values (β= -20.682, t = -3.292; P = 0.002) and log-diastolic blood pressure levels (β= 21.118, t = 3.784; P < 0.001) were independently correlated with LVEDP., Conclusion: When compared with conventional echocardiographic parameters, other longitudinal strain, and SR indices, SRIVRT independently predicted LVEDP in conjunction with log diastolic blood pressure. We suggest that SRIVRT is a valuable parameter to evaluate diastolic function in patients with preserved EF., (Published on behalf of the European Society of Cardiology.

Objective: We aimed to assess the effects of electronic nicotine delivery system (ENDS) or also termed electronic cigarette vapor on the laryngeal mucosa of rats., Materials and Methods: Sixteen female Wistar albino rats were divided into two groups. The study group was exposed to ENDS vapor for 1 hour/day for 4 weeks. The control group was not subjected to any chemical or physical stimulus. The vocal folds of the study and control group rats were evaluated histopathologically by hematoxylin and eosin staining and immunohistochemically by Ki67 staining. Epithelial distribution, inflammation, hyperplasia, and metaplasia were evaluated., Results: Epithelial distribution and inflammation did not differ between the two groups. Two cases of hyperplasia were detected in the study group but there was no hyperplasia in the control group. Four cases of metaplasia were detected in the study group and one case in the control group. Statistical analysis revealed no significant difference between the study and control groups (P = 0.131 and 0.106, respectively)., Conclusions: Exposure to ENDS for 4 weeks caused hyperplasia and metaplasia of the laryngeal mucosa of rats but this was not significant statistically. These results implemented that further studies with larger cohort and longer duration are required to evaluate long-term effects., (Copyright © 2015 The Voice Foundation. Published by Elsevier Inc.

In this study a new solid-state ion selective electrode which is easy to prepare and sensitive to arsenate ion concentration is prepared. The solid salts used in the electrode composition were Cu2S, Ag3AsO4 and Ag2S. The principal component of the electrode was Ag3AsO4. The measurements were made in constant ionic strength using 0.1M NaNO3 and at room temperature. The potentiometric response of electrodes prepared in various compositions was investigated against arsenate ion concentration. The highest slope was obtained with 40% Ag3AsO4, 30% Cu2S and 30% Ag2S. This electrode showed linear response for arsenate ion in the 10(-5)-10(-1) M concentration range. An analytically useful potential change occurred, from 1×10(-6) to 1×10(-1) M arsenate. The slope of the linear portion was about 19±2 mV/10-fold change in arsenate concentration. The lifetime of the electrode was more than two years, when used at least 4-5 times a day, and the response time was about 20-30s depending on the concentration changes. The interference of most common ions and the effect of pH (6-10) have been investigated. This electrode has been used for the determination of arsenate ion in beer sample., (Copyright © 2015 Elsevier B.V. All rights reserved.)

Objective: The aim of this study is to detect the accuracy rate of emergency physicians' (EPs') interpretations of cranial computed tomography (CT) of a special patient group, the patients younger than the age of 2 years with mild head trauma., Methods: The study took place in a research and training hospital within a period of 3 months and included a total of 156 patients. The scans were interpreted by the EPs, and the predicted results were recorded in the patients' files; simultaneous interpretations of the on-call radiologist were also recorded. The interpretations were scanned retrospectively at the end of each month, compared, and recorded., Results: With reference to the radiologists' reports, the sensitivity and the specificity of EPs' interpretations of cranial CT were 76.9% and 95.1%, respectively. Concordance of both groups' interpretations was 93.6%. The area under the curve (AUC) value in receiver operating characteristic (ROC) analysis, which reflects these results, was calculated as 0.860 (95% confidence interval, 0.740-0.981). This value was found to be statistically significant (P < .001). False-negative and false-positive values were 23% and 4.9%, respectively. No negative clinical outcomes were observed due to nonconcordance interpreted cases (6.4%)., Conclusions: Emergency physicians can interpret safely the cranial CTs of patients younger than the age of 2 years with mild head trauma, until the radiologists' reports are obtained. However, the anatomic diversities of these patients' age group should be taken into consideration., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Pericardiocentesis is a life-saving procedure performed in cardiac tamponade cases occurring in infective, inflammatory or malignancy conditions, or following percutaneous coronary intervention, cardiac device implantation or catheter ablation. In spite of advanced imaging methods, a substantial risk of complication persists. Emergent surgical intervention may be required, in particular during advancement of the catheter into the heart chambers or in cases of wall rupture. Furthermore, in all these cases, patients have a high risk of surgery because of existing comorbidities. This case presents a patient suspected of tuberculous pericarditis who underwent diagnostic pericardiocentesis complicated by right ventricular puncture. The catheter in the right ventricle was withdrawn via a second catheter placed in the pericardial cavity. Spontaneous blood control was established, and with no increase in pericardial effusion surgical intervention was not required. This method can be applied in certain conditions, including cardiac injury caused by pericardiocentesis or intracardiac manipulations, thus eliminating the need for high-risk surgical intervention.

Objectives/hypothesis: To evaluate the psychological effects of dysphonia in voice professionals compared to non-voice professionals and in both genders., Study Design: Cross-sectional analysis., Methods: Forty-eight 48 voice professionals and 52 non-voice professionals with dysphonia were included in this study. All participants underwent a complete ear, nose, and throat examination and an evaluation for pathologies that might affect vocal quality. Participants were asked to complete the Turkish versions of the Voice Handicap Index-30 (VHI-30), Perceived Stress Scale (PSS), and the Hospital Anxiety and Depression Scale (HADS). HADS scores were evaluated as HADS-A (anxiety) and HADS-D (depression). Dysphonia status was evaluated by grade, roughness, breathiness, asthenia, and strain (GRBAS) scale perceptually. The results were compared statistically., Results: Significant differences between the two groups were evident when the VHI-30 and PSS data were compared (P = .00001 and P = .00001, respectively). However, neither HADS score (HADS-A and HADS-D) differed between groups. An analysis of the scores in terms of sex revealed that females had significantly higher PSS scores (P = .006). The GRBAS scale revealed no difference between groups (P = .819, .931, .803, .655, and .803, respectively). No between-sex differences in the VHI-30 or HADS scores were evident, Conclusions: We found that voice professionals and females experienced more stress and were more dissatisfied with their voices., Level of Evidence: 4., (© 2015 The American Laryngological, Rhinological and Otological Society, Inc.)

BCG (Bacillus Calmette-Guérin) vaccine is a widely used vaccine with the recommendation of World Health Organization to protect children against miliary tuberculosis (TB) and TB meningitis. Severe side effects related to this vaccine mostly manifest in the presence of underlying immunosuppressive disease. In this report, an infant case with unknown chronic granulomatous disease (CGD) who developed disseminated BCG infection after administration of BCG vaccine, was presented. High fever, left axillary lymphadenopathy and hepatosplenomegaly have developed in a 3-month 28-day female infant, without a known health problem, following BCG vaccination. The acid-fast bacilli (ARB) was isolated from the material of excised lymph node cultivated in Löwenstein-Jensen medium, and the isolate was identified as Mycobacterium bovis. Mycobacterium tuberculosis complex DNA was detected in the axillary lymph node sample by polymerase chain reaction. Anti-tuberculous treatment included 20 mg/kg of rifampicin+10 mg/kg of isoniazid+15 mg/kg of ethambutol+30 mg/kg of streptomycin was started. The patient was then further evaluated for immunodeficiency and on the basis of the results of dihydroamine and LAD (lymphocyte adhesion defect) tests, diagnosed as autosomal recessive CGD. Based on the anamnesis, there was no known immunodeficiency history both in the case during neonatal period and her family members. Interferon-gamma therapy, which is recommended for the patients with CGD living in endemic areas, was initiated. Our patient's fever dropped at the 15th day of anti-tuberculosis treatment, and she was discharged on the 35th day and continued to receive treatment at home. The patient was followed up at outpatient clinic and had no additional complaints; her hepatosplenomegaly was back to normal at the third month. As a result, since BCG vaccine is contraindicated in CGD carriers, newborns with a family history of CGD should be immunologically examined and BCG vaccine should be avoided until the results are obtained. In addition, newborns without a family history, diagnosed as disseminated mycobacterial infection following BCG vaccination, should be evaluated for an underlying immunodeficiency condition.
