Abstract
Abstract
Purpose
Detection of atrial fibrillation (AF) after stroke impacts patient management. However, detection of AF is difficult due to its paroxsysmal nature. We sought to test the hypothesis that echocardiographic quantification left atrial (LA) mechanics in patients with stoke can be an imaging biomarker to predict AF.
Methods
We enrolled prospectively and consecutively 131 patients in normal sinus rhythm with a new diagnosis of ischemic stroke. All patients underwent 48-hour Holter monitorization, transthoracic echocardiography with saline injection in addition to routine work-up of stroke evaluation. Two-dimensional and Doppler studies, together with most up-to-date LA quantification tools were performed including 3-dimensional LA phasic volumes (maxiumum and minimum LA Volume index - LAVImax, LAVImin) and LA strain quantification (average strain from apical 4- and 2-chamber during reservoir (Ss) and contraction (Sa) phases). Patients were followed-up and underwent second 48-hour Holter monitorization 6-12 months later if no etiologic cause was found. Any AF episode lasting >30 seconds was considered significant parosysmal AF.
Results
In 49 patients, causes other than AF were identified (Noncryptogenic). In 43 patients no discernable cause was found (NoAF Cryptogenic). Paroxysmal AF episodes lasting longer than 30 sec were documented in 27 patients at first 48-hour Holter and in 12 patients during follow-up (9.2 ± 3.1 months) either by second 48-hour Holter monitorization or clinically (AF cryptogenic). LAVImax and LAVImin were significantly increased, Ss and Sa were significantly reduced in patients with AF as compared to No AF and Noncryptogenic groups (Table). LA volumes and strain measures predicted AF development independently of CHA2DS2-VASc score. Better discrimination between No AF and AF groups was obtained after second Holter monitorization that enabled detection of more cases with paroxysmal AF (Figure).
Conclusions
Our findings underscore the value of echocardiographic assessment of LA function as a marker of AF development and for selection of patients who could benefit from empiric anticoagulation.

Abstract
BACKGROUND Testosterone level of < 50 ng/dL has been used to define castrate level after surgery or after androgen deprivation treatment (ADT) in metastatic prostate cancer (PC).
AIM To evaluate the effect of two different castrate testosterone levels, < 50 and < 20 ng/dL, on biochemical relapse free survival (BRFS) in patients with non-metastatic intermediate and high risk PC receiving definitive radiotherapy (RT) and ADT.
METHODS Between April 1998 and February 2011; 173 patients with intermediate and high risk disease were treated. Radiotherapy was delivered by either three-dimensional-conformal technique to a total dose of 73.4 Gy at the ICRU reference point or intensity modulated radiotherapy technique to a total dose of 76 Gy. All the patients received 3 mo of neoadjuvant ADT followed by RT and additional 6 mo of ADT. ASTRO Phoenix definition was used to define biochemical relapse.
RESULTS Median follow up duration was 125 months. Ninety-six patients (56%) had castrate testosterone level < 20 ng/dL and 139 patients (80%) had castrate testosterone level < 50 ng/dL. Both values are valid at predicting BRFS. However, patients with testosterone < 20 ng/dL have significantly better BRFS compared to other groups (P = 0.003). When we compare two values, it was found that using 20 ng/dL is better than 50 ng/dL in predicting the BRFS (AUC = 0.63 vs 0.58, respectively).
CONCLUSION Castrate testosterone level of less than 20 ng/dL is associated with better BRFS and is better in predicting the BRFS. Further studies using current standard of care of high dose IMRT and longer ADT duration might support these findings.

Abstract
PURPOSE To validate the clinical outcomes and prognostic factors in prostate cancer (PCa) patients with Gleason score (GS) 8-10 disease treated with external beam radiotherapy (EBRT) + androgen deprivation therapy (ADT) in the modern era. METHODS Institutional databases of biopsy proven 641 patients with GS 8-10 PCa treated between 2000 and 2015 were collected from 11 institutions. In this multi-institutional Turkish Radiation Oncology Group study, a standard database sheet was sent to each institution for patient enrollment. The inclusion criteria were, T1-T3N0M0 disease according to AJCC (American Joint Committee on Cancer) 2010 Staging System, no prior diagnosis of malignancy, at least 70 Gy total irradiation dose to prostate ± seminal vesicles delivered with either three-dimensional conformal RT or intensity-modulated RT and patients receiving ADT. RESULTS The median follow-up time was 5.9 years (range 0.4-18.2 years); 5‑year overall survival (OS), biochemical relapse-free survival (BRFS) and distant metastases-free survival (DMFS) rates were 88%, 78%, and 79%, respectively. Higher RT doses (≥78 Gy) and longer ADT duration (≥2 years) were significant predictors for improved DMFS, whereas advanced stage was a negative prognosticator for DMFS in patients with GS 9-10. CONCLUSIONS Our results validated the fact that oncologic outcomes after radical EBRT significantly differ in men with GS 8 versus those with GS 9-10 prostate cancer. We found that EBRT dose was important predictive factor regardless of ADT period. Patients receiving 'non-optimal treatment' (RT doses <78 Gy and ADT period <2 years) had the worst treatment outcomes.

Abstract
e17107 Background: Endometrial cancer(EC) is a heterogeneous disease with diverse histological features and biological behaviour. Microsatellite instability (MSI) which occurs in cancerous tissue secondary to mismatch repair (MMR) defect of hereditary or somatic origin is a well-known feature further diversifying genetic tumor landscape. In this study, we aim to investigate the relationship between MSI and prognosis in patients with early stage EC. Methods: The patients diagnosed with EC between 2004 and 2017 were retrospectively analysed in the study. The demographic characteristics, disease stage, menopausal status, and clinical and laboratory values were noted. MLH1, MSH2, MSH6 and PMS2 antibodies were used to detect microsatellite status within the tumor tissue samples. Results: The mean age of the 93 patients and menopause was 60.6 ± 9.8 and 49.68 ± 4.5 years , respectively. The median follow-up period was 28 (1-110) months. At the time of diagnosis, number of the patients with stage IA, IB, II, III, and IV were 5, 64, 8, 14, and 2, respectively. Forty three patients were grad 1, 23 patients grad 2, and 27 patients were grade 3. In terms of microsatellite status, 59 patients (63.4%) were microsatellite stable (MSS) and 34 patients (36.6%) were microsatellite instable(MSI). There was no significant association between MSI and tumor stage or grade (X2 = 1.97 p = 0.74 and X2= 3.2, p = 0.19, respectively). There was a significant relationship between peritumoral lymphocyte infiltration rate (pTIL) and MSI. PTIL ratio was higher in tumoral tissues with MSI, whereas pTIL was low in MSS tumor tissues (X2= 28.6, p < 0.0001). Patients with MSI tended to have poorer survival than patients with MSS irrespective of disease stage; mOS rates were 76 and 91 months, respectively (p = 0.086). However, patients with early stage disease and MSI had significantly poorer survial in comparison to patients with similar disease stage and MSS: Overall survival rates for patients with MSI and MSS were 75.8 and 94.7 months, respectively (Log-rank p = 0.048). Conclusions: There is a limited number of studies assessing the association between MSI and clinical outcomes in EC. Our study hints at the presence of potential relationship between MSI and pognosis in patients with MSI. Similar to previous studies performed with various types of tumors we found that EC with MSI attract more immune cells to tumor microenvironments. Interestingly, patients with MSI tended to have poorer prognosis despite augmented immune-cell inftration.

Abstract
BACKGROUND Repeated exposure to a given perturbation of the postural control system has been shown to cause learning of more efficient postural strategies for maintaining balance both within a session and over time. It is important to show whether outcomes from treatment strategies are related to the effectiveness of training or are the result of the learning of the test process. OBJECTIVE To investigate the learning effect of the dynamic postural stability evaluation system. METHODS We studied 20 healthy young subjects (13 females and 7 males), with a mean age of 22.3 ± 1.9 years. Limits of stability and postural sway were assessed. All participants completed the standardized dynamic postural stability evaluation test (Bertec, Bertec Corporation, Columbus, OH, USA) seven times. The test was performed in both eyes open and eyes closed conditions. RESULTS There were differences in the limits of stability scores for backward (p= 0.042), left side (p= 0.05), and the total score (p= 0.04). There were significant differences in postural sway anteroposterior direction in perturbed surface with eyes closed condition (p= 0.004) and total limits of stability scores of perturbed surface with eyes closed condition (p= 0.046). CONCLUSIONS The study showed that balance test scores stabilized at different sessions from 1st to 3rd assessment period. Maximum normalized scores were reached at the third trial.

Abstract
Background The aim of this study was to evaluate the prevalence of some gynecological cancer risk factors in a population of female relatives of cancer patients in Hacettepe University Oncology Hospital. Additionally, what are the levels of the women’s awareness /behavior toward available screening tools? Methods An individual cancer risk assessment questionnaire has been developed in the Department of Preventive Oncology, which questions the medical history, health behaviors and cancer awareness, as well as their behavior toward available cancer screening tools. Results The mean age of the study population was 45.7 ± 12.2 years. Median age at menarche was 13 years (IQR, 12–14), 6.9% of the women reported their menarche was before age of 12. About 11.1% of the women had intercourse before age of 18. The median age at first delivery was 22 years. Median BMI was 24.9, with 18.3% of population having obesity. Of the women 65% were current/past smokers. Sixty-two percent of the women had never used condom. About 8% of the women were unaware about mammography and 17.7% about the Pap test. Conclusions This study has documented high tobacco use, low protective condom use and low rates of physical activity. Percentage of some risk factors like early menarche was lower than what was suggested for general Turkish population. Awareness and behavior of the women were better about mammography when compared to the Pap test. Considering our results, some measures should be put in place to increase people’s awareness, and to modify their behavior toward cancer prevention.

Abstract
AIM The aim of this study was to determine the prevalence of childhood psychopathologies in Turkey. METHOD A nation-wide, randomly selected, representative population of 5830 children (6-13 years-old) enrolled as a 2nd,3rd or 4th grade student in 30 cities were evaluated for presence of a psychiatric or mental disorder by a Sociodemographic Form, Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL), and DSM-IV-Based Screening Scale for Disruptive Behavior Disorders in Children and Adolescents scales. Impairment criterion was assessed via a 3 point-Likert scale by the parent and the teacher independently. RESULTS Overall prevalence of any psychopathology was 37.6% without impairment criterion, and 17.1% with impairment criterion. Attention-deficit hyperactivity disorder was the most frequent diagnosis, followed by anxiety (19.5% and 16.7% without impairment, 12.4% and 5.3% with impairment, respectively). Lower education level and presence of a physical or psychiatric problem of the parents were independent predictors of any psychopathology of the offspring. CONCLUSION This is the largest and most comprehensive epidemiological study to determine the prevalence of psychopathologies in children and adolescents in Turkey. Our results partly higher than, and partly comparable to previous national and international studies. It also contributes to the literature by determining the independent predictors of psychopathologies in this age group.

Abstract
Intradialytic hypotension (IDH) is related to high morbidity and mortality. There is evidence that arginine-vasopressin (AVP) responses could play a role. Copeptin is a reliable biomarker of AVP. In this study, copeptin, aldosterone, epinephrine, and norepinephrine levels in patients with IDH were evaluated throughout a hemodialysis (HD) session and compared with the control group. The study includes 15 patients who were normotensive during HD and 15 patients with IDH with a minimum HD vintage of 1 year. Blood samples were collected before the initiation of an HD session (T0 ), in the mid-session for control group, 30 min after mean arterial pressure drop for IDH patients (T1 ), and at the end of the session (T2 ). Groups had similar demographic features and health parameters, interdialytic weight gains, and ultrafiltration amounts. The IDH group had a mean arterial pressure decline of 39.9 (±6.4) mm Hg. Copeptin levels of the control group increased an average of 79.9 (±97.5) pmol/L at T1 and an additional 24.8 (±33.9) pmol/L at T2 . In the IDH group, copeptin level increases at T1 and T2 were 3.2 (±5.5) pmol/L and 34 (±44.6) pmol/L, respectively. Copeptin levels of the IDH group were significantly lower at T1 (P < 0.001) and at the T0 -T2 interval than control group (P = 0.05). In the control group, aldosterone levels distinctly decreased, and in the IDH group, aldosterone levels were elevated (P < 0.001). Small changes were detected in epinephrine and norepinephrine levels for both groups but did not reach significance (P = 0.6 and P = 0.3, respectively). Lower copeptin level alterations suggest inadequate AVP responses in patients with IDH.

Abstract
We aimed to evaluate effects of β-hydroxy-β-methylbutyrate, L-glutamine, and L-arginine (HMB/GLN/ARG) on radiation-induced acute intestinal toxicity. Forty rats were divided into four groups: group (G) 1 was defined as control group, and G2 was radiation therapy (RT) control group. G3 and G4 were HMB/GLN/ARG control and RT plus HMB/GLN/ARG groups, respectively. HMB/GLN/ARG started from day of RT and continued until the animals were sacrificed 10 days after RT. The extent of surface epithelium smoothing, villous atrophy, lamina propria inflammation, cryptitis, crypt distortion, regenerative atypia, vascular dilatation and congestion, and fibrosis were quantified on histological sections of intestinal mucosa. Statistical analyses were performed using the analysis of variance (ANOVA) test. There were significant differences between study groups regarding extent of surface epithelium smoothing, villous atrophy, lamina propria inflammation, cryptitis and crypt distortion, regenerative atypia, vascular dilatation and congestion, and fibrosis (p values were 0.019 for fibrosis, <.001 for the others). Pair-wise comparisons revealed significant differences regarding surface epithelium smoothing, villous atrophy, lamina propria inflammation, cryptitis, vascular dilatation, and congestion between G2 and G4 (p values were <.001, .033, <.001, .007, and <.001, respectively). Fibrosis score was significantly different only between G1 and G2 (p = .015). Immunohistochemical TGF-β score of G2 was significantly higher than G1 and G3 (p values were .006 and .017, respectively). There was no difference between TGF-β staining scores of G2 and G4. Concomitant use of HMB/GLN/ARG appears to ameliorate radiation-induced acute intestinal toxicity; however, this finding should be clarified with further studies.

Abstract
BACKGROUND AND AIM Burnout and exhaustion is a frequent problem in oncology nursing. The aim of this study is to evaluate the aspects of oncology nurses about their profession in order to enhance the standards of oncology nursing. MATERIALS AND METHODS This survey was conducted with 70 oncology nurses working at Hacettepe University Oncology Hospital. Data were collected between January-April 2012. Each participant provided a study form comprising questions about sociodemographic information; about difficulties, positive aspects and required skills for oncology nursing; and questions evaluating level of participation and clinical perception of oncology nursing. RESULTS Mean age of nurses was 29.9 ± 5.7 years. More than half of the participants were married (51.4%) and 30% had at least one child. Percent of nurses working in oncology for their entire work life was 75.8%. Most frequently expressed difficulties were exhaustion (58.6%), coping with the psychological problems of the patients (25.7%), and frequent deaths (24.3%); positive aspects were satisfaction (37.1%), changing the perceptions about life (30%), and empathy (14.3%); and required skills were patience (60%), empathy (57.1%), and experience (50%). For difficulties of oncology nursing, 28.3% of difficulties could be attributed to job-related factors, 30.3% to patient-related factors, and 77% of difficulties to individual factors. The independent predictors of participation level of the nurses were self-thoughts of skills and positive aspects of oncology nursing. CONCLUSION According to the findings of this study, nurses declared that working with cancer patients increase burnout, they are insufficient in managing work stress and giving psychological care to patients, but their job satisfaction, clinical skills and awareness regarding priorities of life has increased.

Abstract
BACKGROUND AND PURPOSE Reperfusion is the most significant determinant of good outcome after ischemic stroke. However, complete reperfusion often cannot be achieved, despite satisfactory recanalization. We hypothesized that microvascular protection was essential for achieving effective reperfusion and, hence, neuroprotection. To test this hypothesis, we have developed an in vivo model to differentially monitor parenchymal and vascular reactive oxygen species (ROS) formation. By comparing the ROS-suppressing effect of N-tert-butyl-α-phenylnitrone (PBN) with its blood-brain barrier impermeable analog 2-sulfo-phenyl-N-tert-butylnitrone (S-PBN), we assessed the impact of vascular ROS suppression alone on reperfusion and stroke outcome after recanalization. METHODS The distal middle cerebral artery was occluded for 1 hour by compressing with a micropipette and then recanalized (n=60 Swiss mice). ROS formation was monitored for 1 hour after recanalization by intravital fluorescence microscopy in pial vasculature and cortical parenchyma with topically applied hydroethidine through a cranial window. PBN (100 mg/kg) or S-PBN (156 mg/kg) was administered shortly before recanalization, and suppression of the vascular and parenchymal hydroethidine fluorescence was examined (n=22). Microcirculatory patency, reperfusion, ischemic tissue size, and neurological outcome were also assessed in a separate group of mice 1 to 72 hours after recanalization (n=30). RESULTS PBN and S-PBN completely suppressed the reperfusion-induced increase in ROS signal within vasculature. PBN readily suppressed ROS produced in parenchyma by 88%. S-PBN also suppressed the parenchymal ROS by 64% but starting 40 minutes later. Intriguingly, PBN and S-PBN comparably reduced the size of ischemic area by 65% and 48% (P>0.05), respectively. S-PBN restored the microvascular patency and perfusion after recanalization, suggesting that its delayed parenchymal antioxidant effect could be secondary to improved microcirculatory reperfusion. CONCLUSIONS Promoting microvascular reperfusion by protecting vasculature can secondarily reduce parenchymal ROS formation and provide neuroprotection. The model presented can be used to directly assess pharmacological end points postulated in brain parenchyma and vasculature in vivo.

Abstract
346 Background: Although clinical efficacy of gemcitabine in combination with nabpaclitaxel has been shown to be superior to single agent gemcitabine in a randomize phase 3 trial, data are lacking on the quality of life of this combination regimen as first-line therapy in patients with unresectable locally advanced or metastatic pancreatic adenocarcinoma. Methods: We randomly assigned 125 patients with an Eastern Cooperative Oncology Group performance status score of 0 or 1 to receive gemcitabine, 1000 mg/m2 plus nabpaclitaxel 125 mg/m2 or gemcitabine at a dose of 1000 mg per square meter weekly for 7 of 8 weeks and then weekly for 3 of 4 weeks. Treatment continued until disease progression or unacceptable toxicity. The primary end point was 3-months deterioration-free rate (percentage of patients free from definitive deterioration) and quality of life of patients. Results: The median overall survival was 9.92 months in the gemcitabine plus nabpaclitaxel group as compared with 5.95 months in the gemcitabine group (hazard ratio for death, 0.642, 95% confidence interval, 0.422 to 0.866; p < 0.038). Median progression-free survival was 6.28 months in the combination group and 3.22 months in the gemcitabine group (hazard ratio for disease progression, 0.582; 95% CI, 0.391 to 0.866; p < 0.008). The objective response rate was 37.1% in the combination group versus 23.7% in the gemcitabine group (p < 0.009). Median time to deterioration was 3.68 months in the gemcitabine arm versus 5.36 months in the combination arm. More data on quality of life will be presented. Conclusions: As compared with gemcitabine, gemcitabine plus nabpaclitaxel was associated with an overall and progressive free survival advantage, with increased response rate, without increasing toxicity and deterioration of quality of life. Gemcitabine and nabpaclitaxel combination regimen with this form is a preferable option for the treatment of patients with advanced pancreatic cancer Clinical trial information: EudraCT: 2013-004180-32.
