Item Gender and Exposure to Childhood Violence are Important Determinants of Domestic Violence Among Academics(2023) Kurt, Gonca; Akin, Ayse; 38034745Domestic violence is a common and significant social problem that threatens public health, violates human rights, and poses significant obstacles to national development. This study aimed to evaluate both male and female academics' knowledge and views on domestic violence, and determine its incidence and risk factors among academics. Participants comprised 304 academics working at universities, who were selected by cluster sampling from seven regions of Turkey. Data were analyzed using thematic coding, descriptive statistics, and multivariate logistic regression. Of the 304 participants, 56.9 % were female academics. The incidence of domestic violence among the academics was 21.4 %, with 25.4 % of female and 16.0 % of male academics reporting having experienced it. Academics who were victims of domestic violence were mostly exposed to it from their spouses. Academics also reported experiencing emotional violence. Female academics were 2.3 times more likely to experience domestic violence than men. Academics who were exposed to violence in childhood experienced 14.1 times more domestic violence than those who were not. Although it seems that a high status in society as an academic reduces the rates of exposure to domestic violence, gender, and witnessing or experiencing violence in early childhood are the most important risk factors for this population. The lack of a solution for domestic violence can be attributed to non-deterrent punishments.Item Epicardial Adipose Tissue Thickness and Carotid Intima-Media Thickness in Hemodialysis Patients(2017) Aydin, Elcin; Altin, Cihan; Sakalhoglu, Onur; Yilmaz, Mustafa; Gezmis, Esin; Sade, Leyla Elif; Muderrisoglu, Haldun; 0000-0002-9635-6313; 0000-0003-0907-3647; 0000-0002-1001-6028; 0000-0003-3737-8595; 28559657; AAG-8233-2020; AAI-8276-2021; AAE-8301-2021; AAQ-7583-2021; HGC-1839-2022Background: It is well-known that cardiovascular risk and all-cause mortality is increased in hemodialysis patients. Epicardial fat thickness (EFT), which reflects visceral adiposity, has been suggested as a new cardiometabolic risk factor. The purpose of this study was to investigate EFT in hemodialysis patients. Methods: A total of 144 consecutive patients (60 hemodialysis patients and 84 controls) were enrolled into the study, and patients with diabetes mellitus and cardiovascular diseases (CVD) were excluded. EFT was measured on the free wall of the right ventricle at end-diastole from the parasternal long-axis view by standard transthorasic 2D echocardiography. Results: The groups were similar in terms of sex distribution, age, blood pressure, heart rate and frequencies of CAD risk factors including smoking status, family history of CAD and hypertension. There were no significant differences between the hemodialysis patients and controls in 2D echocardiographic parameters, including ejection fraction and biochemical parameters except low-density lipoprotein, high-density lipoprotein and c-reactive protein. Despite having lower body mass index, EFT levels were significantly higher in hemodialysis patients compared to the controls (8.0 +/- 2.2 mm vs. 5.8 +/- 1.9 mm; p < 0.01). In multivariate linear regression analysis we determined that hemodialysis patient status was found to be an independent predictor for both EFT ((3 = 0. 700, p = 0.014) and carotid intima-media thickness (CIMT, beta = 0. 614, p = 0.047). Conclusions: Hemodialysis patients are independently associated with high EFT and CIMT.Item Factors affecting the surgical success of trabeculectomy performed as the first surgery in primary pediatric glaucoma(2022) Demirok, Gulizar; Ozkan, Guner; Kaderli, Ahmet; Guvenc, Umay; Yakin, Mehmet; Eksioglu, Umit; 0000-0002-3061-7162; 35353293; ABG-2501-2020Purpose To present the outcomes and factors affecting the success of trabeculectomy performed as the first surgery in primary pediatric glaucoma. Methods Pediatric patients with primary glaucoma who underwent trabeculectomy as the first surgery were retrospectively reviewed. Age, gender, preoperative intraocular pressure (IOP), operation age, axial length, corneal diameter, anterior segment findings, antimetabolite used, complications, and 1-month, 3-months, 1-year, and most recent postoperative findings were recorded. Postoperative IOP with/without medication of 18 mmHg or less was considered successful. Factors that may have affected surgical success were also evaluated using multivariate analysis. Results Included in the study were 48 patients, of whom 30 had primary congenital glaucoma and 18 had juvenile glaucoma. The mean preoperative IOP was 36.84 +/- 6.30 mmHg, and the mean follow-up time was 7.95 +/- 6.93 years. The median operation age value was 100.00 +/- 100.83 (median: 60; IQR: 153) months. The postoperative IOP at the 1-month, 3-months, 1-year, and most recent follow-ups were 15.39 +/- 6.88, 15.70 +/- 7.36, 16.28 +/- 7.86, and 17.48 +/- 8.44 mmHg, respectively (p = 0.565). While there were no postoperative complications in 24 of the patients (50.0%), the most common complications were choroidal detachment and hypotony. Postoperative complication development was found to be significant as a factor affecting surgical success in the multivariate logistic regression analysis. Surgical success rates for all of the patients were 71.7%, 65.9%, 65.0%, and 61.4% at the 1-month, 3-months, 1-year, and most recent follow-ups, respectively. A significant difference was found between the congenital and juvenile groups in terms of surgical success only at 3 months (p = 0.953, p = 0.042,p = 0.191, p = 0.218; respectively). Discussion/Conclusion The fact that surgical success was partially higher in the juvenile group confirmed the idea that the results of trabeculectomy will be more favorable in patients of older age and without anterior segment anomalies.Item Assessing risk factors for postoperative hypotony in Ahmed glaucoma valve implantation surgery(2021) Kaderli, Ahmet; Demirok, Gulizar; Uney, Guner; Yakin, Mehmet; Gunal, Berku; Eksioglu, Umit; 34019191Purpose To assess the risk factors associated with the development of hypotony after Ahmed glaucoma valve (AGV) implantation. Methods One hundred and ninety-three eyes of 177 patients with various types of glaucoma that were treated with AGV implantation were retrospectively evaluated. Intraocular pressure lower than 6 mmHg related to the surgery is defined as postoperative hypotony. Patients' demographic characteristics, type of glaucoma, preoperative and postoperative visual acuity, necessity of antiglaucoma treatments, lens status, previous ocular surgeries, intraocular pressure (IOP) measurements before and after surgeries, the need for additional procedures and postoperative complications were recorded from the patients' charts. Results Hypotony was seen in 68 of 193 eyes (35.2%) postoperatively. In 45 eyes (23.3%), it has occurred in first postoperative day and in 23 eyes (11.9%) after the first day within the first week. There was no difference in intraocular pressures between two groups in the first year follow-up. Pre- and postoperative best-corrected visual acuities, age and gender were not statistically different between hypotony and no hypotony groups (p > 0.05). Also, lens status, history of previous ocular surgery, type of glaucoma and number of preoperative glaucoma medication usage were not found to be different between groups (p > 0.05). Conclusions Potential risk factors such as age, sex, lens status, history of previous ocular surgeries, preoperative glaucoma medication usage or glaucoma type are not found to influence upon postoperative hypotony prevalence for AGV surgery. Surgery type and personal ocular factors, which could not be determined beforehand, could be more important than demographic features.Item A FMEA based novel intuitionistic fuzzy approach proposal: Intuitionistic fuzzy advance MCDM and mathematical modeling integration(2021) Yener, Yelda; Can, Gulin FeryalThis study proposes a novel three-stage intuitionistic fuzzy risk assessment (RA) approach based on Failure Modes and Effects Analysis (FMEA). In this study, it was paid attention for considering real constraints of firms such as capital, time etc. to prevent nan-fatal failure modes (FMs), interactions between FMs and risk level similarities created by risk factors (RFs). At the first stage of the proposed approach, RFs' weights are computed by a new intuitionistic fuzzy weighting method considering similarities between RFs for risk levels that they can create. At the second stage, Modified Intuitionistic Fuzzy Multi Attribute Border Approximation Area (MIF-MABAC) including interactions between FMs is used to determine the rankings of FMs by using Extended Haussdorff distance function. At the third stage, two intuitionistic fuzzy mathematical models are established to show the effect of the real constraints of the firm to identify the risk types (RTs) that must be avoided primarily. It was seen that the first model gives the same ranking results with the MIF-MABAC. Additionally, when including the real constraints, the first model can give the more suitable results than the second model. The results obtained from the first model show that experts' assessments and mathematical modeling identify the same FMs for preventing primarily. This study is the first one to suggest a new RA approach that reflects the real constraints of the firms to RA. Additionally, this is the first study that models' interactions between FMs and risk level similarities created by RFs.Item Correlation of Clinical Risk Factors with Diffusion-Weighted Magnetic Resonance Images in Prostate Cancer Patients Treated with Definitive Radiotherapy(2015) Erbay, Gurcan; Onal, Cem; Guler, Ozan C.; Karadeli, Elif; Koc, ZaferThis study is aimed to correlate apparent diffusion coefficient (ADC) values and clinical T-stage, serum PSA, pathology Gleason scores. We also further analyzed whether ADC values could be used to appropriately define the risk groups. 135 biopsy-proven, radiotherapy-(RT)-treated, prostate cancer patients who underwent pre-RT DW-MRI and standard T2W pelvic MRI were included. ADC and normalized ADC (nADC) values were calculated from DW-MRI delivered a median 8.1 weeks after prostate biopsy. ADC values were correlated with clinical risk factor values by using Pearson correlation test. ADCs in low-, intermediate-, and high-risk patients were 0.873 +/- 0.122X10(-3) mm(2)/s, 0.763 +/- 0.124X10(-3) mm(2)/s, and 0.701 +/- 0.132X10(-3) mm(2)/s (p = 0.001), respectively. Patients with preRT PSA <10 ng/mL had significantly higher ADCs than patients with preRT PSA 10-20 ng/mL (p = 0.02) or >20 ng/mL (p < 0.001). Mean ADC for patients with Gleason score <7 was significantly higher than patients scoring 7 (p = 0.001) or >7 (p < 0.001). Clinical stageItem Maternal and perinatal characteristics of small-for-gestational-age newborns: Ten-year experience of a single center(2017) Gulumser, Cagri; Uysal, Nihal Sahin; Yanik, Filiz Bilgin; 0000-0001-5385-5502; 28490415; AAA-9475-2020Objective: To analyze the maternal and perinatal characteristics of small-for-gestational-age (SGA) newborns compared with appropriate-for-gestational- age (AGA) newborns in singleton pregnancies managed at our hospital between January 2006 and December 2015. Material and Methods: The study (n=456) and control (n=4925) groups included pregnancies resulting in SGA and AGA newborns, respectively. Additionally, two SGA subgroups were defined according to abnormal (n=34) and normal (n=57) Doppler findings. Maternal demographic features; intracytoplasmic sperm injection (ICSI) pregnancies; gestational age at delivery; birth weight; major congenital anomalies, karyotype abnormalities, and genetic syndromes; maternal and obstetric problems such as hypertensive disorders, diabetes, oligohydramnios, preterm birth; admission to the neonatal intensive care unit (NICU), and perinatal mortality were recorded, and the two groups were compared with respect to these parameters. Results: Mean maternal age, parity, gestational age at delivery, and birthweight were significantly lower; the frequencies of ICSI pregnancies, hypertensive disorders, oligohydramnios, preterm delivery, major congenital anomalies, karyotype abnormalities and genetic syndromes, admission to the NICU and perinatal mortality were significantly higher in the study group (p<0.05). None of the study parameters were significantly different between the two SGA subgroups (p>0.05). Conclusion: The association of SGA with ICSI pregnancies, hypertensive disorders, oligohydramnios, preterm delivery, congenital/chromosomal anomalies, NICU admission and perinatal mortality may be important in perinatal care. Clinical suspicion of SGA necessitates appropriate monitorization and management. Although obstetric outcomes were not significantly different between the two SGA subgroups with abnormal and normal Doppler findings in this study, this finding must be evaluated with caution due to the small sizes.Item Burnout Syndrome Among Physicians: The Role of Socio-Demographic Characteristics(2017) Ozkula, Guler; Durukan, Elif; 0000-0002-8579-5564; AAJ-8621-2021Objective: Burnout is a syndrome that occurs in occupational groups, which are in close relation with people and includes dimensions of; emotional exhaustion, depersonalization and low sense of personal accomplishment. The aim of the present study is to investigate the relationship between socio-demographic characteristics and burnout syndrome in academic personel working at a hospital of Faculty of Medicine. Method: 258 physicians working at Baskent University Ankara Hospital have been included in the present study voluntarily, between January - April 2014 and they have been administered Socio-Demographic Data Form and Maslach Burnout Inventory. Results: Age, academic title, time span in the profession and at the institution, the number of patients daily examined, administrative tasks, receiving research supports, the number of lectures given were related to all dimensions of burnout: emotional exhaustion, depersonalization, and personal accomplishment. Personnel assignment, the number of monthly shifts, daily duration of work were related to emotional exhaustion and depersonalization. Specialty preferences and intention to continue on the profession were associated with emotional exhaustion and personal accomplishment. Personnel assignment criteria and time reserved for academic study were related to only emotional exhaustion whereas accessibility to scientific literature was linked to personal accomplishment. Conclusion: Older age, having an academic title, longer time span in the profession and at the institution, concidering the long term consequences of specialty selection are all individual factors that can be related to burnout syndrome. Developing health policies for an optimal organization of daily work duration, number of patients daily examined and personnel assignment criteria could prevent burnout. Also developing organizational climate to create time for academic study, supporting researches, increasing accessibility to scientific literature and optimization of education seminars in academic physicians could protect them from burnout syndrome. Prospective studies modeling individual and organizational risk factors for burnout on academic physicians will help to further illuminate the measures to protect physicians from burnout syndrome and also contribute to the enhancement of treatment service quality and foster the contribution to academic arena.
