Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a curative treatment for acute myeloblastic leukemia (AML). Because the conditioning regimen of busulfan plus cyclophosphamide carries significant risks of toxicity, we evaluated the factors affecting survival after fludarabine replacement instead of cyclophosphamide. Methods. The study included 55 patients who underwent allo-HSCT for AML and received busulfan, fludarabine, and antithymocyte globulin (ATG). Results. Forty-eight patients received a myeloablative regimen; 7 patients received a reduced-intensity conditioning regimen. The neutrophil and platelet engraftment times were 12 days (range 9 to 20) and 12 days (range 7 to 19), respectively. Graft-vs-host disease (GvHD) developed in 10% and 50% of the patients, respectively. Seven patients received donor lymphocyte infusion. Of them, 5 patients developed grade I or II GvHD, one grade IV GvHD. The median follow-up period was 20.6 months. The predicted progression-free survival (PFS) at 1 and 3 years after transplantation was 78% and 74%, respectively. The overall survival (OS) at 1, 3, and 5 years was 76%, 74%, and 62%, respectively. Treatmen-trelated mortality (infection in 1 patient, GvI-ID in 2 patients) occurred in 3 patients (5.5%). Multivariate analysis revealed that OS and PFS were not influenced by age, dose of busulfan or ATG, or presence of cytomegalovirus antigenemia. Acute GvHD and pretransplantation minimal residual disease positivity negatively affected the transplant outcome. The presence of active disease at the time of transplantation was found as an independent risk factor for AML. Conclusions. Busulfan- and fiudarabine-based conditioning regimens are effective for AML, and have acceptable toxicity, morbidity, and mortality.Item Post-transplantation Anemia Predicts Cardiovascular Morbidity and Poor Graft Function in Kidney Transplant Recipients(2015) Demirci, B. Gurlek; Sezer, S.; Sayin, C. B.; Tulal, E.; Uyar, M. E.; Acar, F. N. Ozdemir; Haberal, M.; 0000-0002-3462-7632; 0000-0002-5682-0943; 26036548; IAO-2608-2023; AAJ-8097-2021; AAK-1697-2021Objective. We aimed to investigate whether low post-transplantation-period hemoglobin levels are predictive of cardiovascular morbidity in terms of left ventricular (LV) hypertrophy and vascular stiffness and to determine the contributing factors of post-transplantation anemia in kidney transplant (KT) recipients. Methods. One hundred fifty (mean age, 38.9 +/- 10.8 y; 113 male) KT recipients with functioning grafts were enrolled in the study. All subjects underwent clinical and laboratory evaluations (24-hour urinary protein loss, complete blood count) and transthoracic echocardiography to assess LV systolic function. Arterial stiffness was measured by means of carotid-femoral pulse-wave velocity (PWV). Mean hemoglobin levels were analyzed at the 1st, 6th, 12th, and 24th months after transplantation. Patients were divided into 2 groups according to presence of anemia: patients with anemia (group 1; n = 120) and normal (group 2; n = 30). Results. PWV values (6.8 +/- 1.9 m/s vs 6.4 +/- 1.1 m/s in groups 1 and 2, respectively; P = .002) and LV mass index (LVMI; 252.1 +/- 93.7 g/m(2) vs 161.2 +/- 38.5 g/m(2) groups 1 and 2, respectively; P = .001) were significantly higher in group 1. Estimated glomerular filtration rate and (64 +/- 28.5 m/min vs 77.8 +/- 30 m/min in groups 1 and 2, respectively; P = .001) LV systolic function (57.2 +/- 5.8% vs 77.8 +/- 30% in groups 1 and 2, respectively; P < .005) were significantly lower in group 1. In regression analysis, LV systolic function and LVMI were predictors of post-transplantation hemoglobin levels. Conclusions. Post-transplantation anemia contributes to cardiovascular morbidity by deteriorating LV function and increasing PWV and is therefore associated with poor prognosis for graft survival. Early correction of post-transplantation anemia, especially with the use of erythropoietin, may be beneficial for both graft and recipient survivals.Item Post-Transplant C-Reactive Protein Predicts Arterial Stiffness and Graft Function in Renal Transplant Recipients(2015) Demirci, B. Gurlek; Sezer, S.; Colak, T.; Sayin, C. B.; Tutal, E.; Haberal, M.; 0000-0002-8372-7840; 0000-0002-3462-7632; 26036547; AAJ-8554-2021; AAJ-8097-2021Background. The aim of this study was to evaluate the renal and cardiovascular outcomes of post-transplant c-reactive protein (CRP) levels. Methods. One hundred fifty renal transplant recipients (113 men; median age, 38.9 10.8 years) were cross-sectionally analyzed. Mean pre-transplant and post-transplant CRP levels were analyzed by the 1st, 3rd, 6th, 12th, and 24th months of transplantation. Patients were divided into 3 groups according to mean post-transplantation CRP levels: group 1 (CRP >20 mg/L and fluctuating levels; n = 34), group 2 (CRP, 6-20 mg/L; n = 40), and group 3 (CRP <6 mg/L; n = 76). Arterial stiffness was measured by means of carotid femoral pulse-wave velocity (PWv) by use of the SphygmoCor system. Results. Patients in group 1 had significantly lower estimated glomerular filtration rate (eGFR) (P = .000) and left ventricular systolic function and higher duration of dialysis before transplantation, pulse-wave velocity (PWv), proteinuria, and left ventricular mass index when compared with the other two groups. In regression analysis, eGFR and PWv were detected as the predictors of post-transplantation CRP levels. Conclusions. Fluctuating and high stable (>20 mg/L) post-transplant CRP levels predict eGFR, proteinuria, left ventricular mass index, and PWv after transplantation. Thus, CRP levels may be a useful marker to anticipate graft survival and cardiovascular morbidity in renal transplant recipients.Item Evaluation of Serum Leptin and Adiponectin Levels in Obese and Lean Asthmatic Children(2015) Koksal, Burcu Tahire; Ozbek, Ozlem Yilmaz; Bayraktar, Nilufer; Kinik, Sibel Tulgar; Yazici, Ayse Canan; 0000-0003-2974-9579; 0000-0002-7886-3688; 0000-0002-3132-242X; 0000-0001-9580-7656; AAJ-2034-2021; Y-8758-2018; AAS-6810-2021; HKW-0623-2023; AAF-2109-2021Background: Adipokines have been claimed for the link between obesity and asthma. The aim of the present study was to evaluate the roles of leptin and adiponectin in children with asthma and/or obesity and their effect on pulmonary functions. Methods: Obese (n=71) and lean asthmatics (n=72), obese non-asthmatics (n=46), and lean healthy children (n=49) were included in the study. Serum leptin and adiponectin levels were compared according to groups and sex. Results: Mean leptin levels of obese asthmatics were higher than those of lean asthmatics (13.19.1 vs. 3.7 +/- 4.4; p<0.001). Serum adiponectin levels of lean asthmatics (16 +/- 7.1) were significantly higher than those of obese asthmatics (12.1 +/- 6.9; p<0.001) and of their lean healthy (13.2 +/- 5.9; p<0.05) counterparts. In obese asthmatics, adiponectin levels were positively correlated with the forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) ratio, and serum leptin levels were inversely correlated with forced expiratory flow (FEF25-75). Leptin/adiponectin ratio was inversely correlated with FEV1/FVC ratio in lean and obese asthmatic patients. Conclusions: The present findings suggest that adiponectin may have protective disease modifying effect(s) in asthmatic children. Anti-inflammatory mechanisms regarding adiponectin may work better in girls than in boys.Item Natural History and Conservative Treatment Outcomes for Hydroceles: A Retrospective Review of One Center's Experience(2018) Acer Demir, Tugba; Ekenci, Berk Yasin; Ozer, Dogancan; Turanoglu, Mehmet Ali; Haberal, Kadem Cem; Bilgin, Elif Bengisu; Hicsonmez, Akgun; 0000-0001-5391-9094; 0000-0002-5939-4548; 29032240; E-4455-2019; GPG-1911-2022OBJECTIVE To elucidate epidemiological data and hydrocele progression, we reviewed pediatric patients diagnosed with hydroceles in our institution retrospectively. MATERIALS AND METHODS We reviewed data from 355 pediatric patients with hydroceles. Questionnaires regarding age at diagnosis, time of delivery, presence of hydroceles in the father and brothers, age at recovery, age at surgery, cause of hydrocele (if present), type of hydrocele, associated pathologies, treatments, and posthydrocelectomy complications were completed by reviewing patients' medical records and interviewing their families. RESULTS Patients with congenital hydroceles were more frequently born prematurely (32.5%) than were patients with noncongenital hydroceles (15.9%; P=.001). Fathers of 10 patients (3.7%) and brothers of 21 patients (7.7%) also had hydroceles. Hydroceles were associated with inguinal hernias on the same side (12.2%), cryptorchidism (7.5%), varicoceles (6.0%), and testis torsion (0.5%). Among patients aged >1 year (n=185), 27 did not undergo operations and healed spontaneously at an average of 5.30 +/- 3.36 months. For children aged >1 year who did not undergo surgery, the rate of spontaneous recovery within 6 months was 77.8% and that within 1 year was 96.3%. CONCLUSION Until strong evidence of hydrocele-induced testicular damage in children arises, we recommend following up congenital hydroceles until at least 1 year and preferably 2 years of age. We recommend following up noncongenital hydroceles for at least 6 months and preferably 1 year if there is no associated pathology indicating the need for earlier surgery such as an inguinal hernia, cryptorchidism, tense hydrocele, testis torsion, or testis mass.

Also we determined whether alexithymia is predictor of suicidal ideation related with SAD. Methods: One hundred and sixty-four SAD (n=57), panic disorder (PD) (n=58), healthy controls (HC) (n=49) subjects (according to DSM-5) were included to study. Alexithymia was measured by Toronto Alexithymia Scale-20(TAS-20), suicidal ideation was measured by Suicidal Ideation Scale (SIS), social anxiety level were evaluated with Liebowitz Social Anxiety Scale and anxiety and depression level evaluated with Beck Depression Inventory and Beck Anxiety Inventory, State and Trait Anxiety Scales. Results: Alexithymia, the rate of was found to be 38.6% in SAD patients and 29.3% in PD patients. In SAD group, significant correlation was found between TAS 20, its factors and SIS. With path analysis, it was found that TAS 20 total scores predicted SIS scores only indirectly and via their effects on trait anxiety and subjective depressive symptoms. Conclusion: In alexithymic SAD patient's suicidal ideation may occur when comorbid depression is present. Based upon the findings alexithymia may not be a good predictor of suicidal ideation for preventing suicidal attempts in patients with social anxiety disorder.Item There Is No Doubt About The Winner Of The Lion-Rabbit Fight(2022) Onal, Cem; Oymak, Ezgi; Guler, Ozan C.; https://orcid.org/0000-0002-2742-9021; 35652580; D-5195-2014
