    Relationship Between Melatonin and Cardiovascular Disease
    (2021) Ozkalayci, Flora; Kocabas, Umut; Altun, Betul U.; Pandi Perumal, Seithikurippu; Altun, Armagan; 0000-0002-3233-8263; 33654615; ABB-5844-2020
    Coronary artery disease (CAD) is one of the leading causes of morbidity and mortality worldwide. The coronary atherosclerotic process involves different pathological mechanisms; inflammation is one of the major triggers for the development of atherosclerotic plaque. Although several studies showed the favorable effects of melatonin on the cardiovascular system (CVS), melatonin seems not to take its rightful place in today's clinical practice. This review aims to point out the role of melatonin on cardiovascular disease (CVD) and its' risk factors. All data were obtained via PuhMed, Wikipedia, and Google.

    Characteristics of Newly Diagnosed Hepatocellular Carcinoma Patients Across Turkey: Prospective Multicenter Observational 3K Registry Study
    (2021) Ozyilkan, Ozgur; 34876392
    Aims: To evaluate patient profile for epidemiological and clinicopathological characteristics and potential risk/prognostic factors in newly diagnosed hepatocellular carcinoma (HCC) patients across Turkey. Methods: A total of 547 patients (mean (SD) age 62.6 (10.3) years, 81.9% were males) were included in this registry study. Data on patient characteristics, etiologies of HCC, laboratory values, and tumor characteristics and stages were recorded at study enrollment. Results: HBV infection (68.2%) was the leading etiology, followed by HCV infection (17.2%), HDV infection (5.5%), alcohol (6.4%), and NAFLD (3.5%), as the major etiologies. Considering that 51.6% of the patients had >5 cm HCC, 44% were Child-Pugh B/C and 57% were BCLC B-D, it appears that a significant group of HCC patients were diagnosed at advanced stages. Of 540 patients, 271 (50.2%) were referred or applied with the diagnosis of HCC. Patients with HCC at presentation had larger tumor size (median (min-max) 6.6 (0-30) vs. 4.8 (0-90) cm, P<.001) and more advanced BCLC stage (Stage C-D in 40.8% vs. 26.4%, respectively, P=.005), compared to patients who were diagnosed during follow-up. Conclusions: Our findings revealed that HBV infection was the leading etiology and a moderate-to-advanced disease was evident in more than half of patients at the time of diagnosis. HCC patients diagnosed at follow-up had smaller tumor size and earlier BCLC stage.

    Impact of Platelet Count in Retinopathy of Prematurity
    (2020) Keskek, Nedime Sahinoglu; Gulcan, Hande; Yilmaz, Gursel; Akkoyun, Imren; 0000-0001-8544-103X; 33389935; T-4258-2017
    Objectives: The aim of the study was to investigate the risk factors for retinopathy of prematurity (ROP), including platelet count. Materials and Methods: This retrospective study analyzed 137 infants in 3 subgroups: no ROP; mild RAP, and severe ROP requiring laser treatment (type 1 ROP). A retrospective review of records was performed and statistical analysis of possible risk factors for ROP including platelet count was evaluated by using logistic regression. Results: Birth weight (BW), gestational age (GA), and low platelet count in the first week after birth were significant risk factors for developing ROP (p=0.038, 0.02, and 0.004, respectively). BW, GA, ventilation, and lower platelet count were associated with progression to type 1 ROP (p=0.004; 0.027, and 0.021, respectively). Conclusion: Lower platelet count in the first week after birth is a risk factor for ROP development in addition to the previously established factors of ventilation need, low BW, and low GA.

    Predictors of in-hospital mortality following redo cardiac surgery: Single center experience
    (2015) Colkesen, Yucel; Coskun, Isa; Cayli, Murat; Gulcan, Oner; 26527452
    Purpose: Redo cardiac operations represent one of the main challenges in heart surgery. The purpose of the study was to analyze the predictors of in-hospital mortality in patients undergoing reoperative cardiac surgery by a single surgical team. Methods: A total of 1367 patients underwent cardiac surgical procedures and prospectively entered into a computerized database. Patients were divided into 2 groups based on the reoperative cardiac surgery (n = 109) and control group (n = 1258). Uni-and multivariate logistic regression analysis were performed to evaluate the possible predictors of hospital mortality. Results: Mean age was 56 +/- 13, and 46% were female in redo group. In-hospital mortality was 4.6 vs. 2.2%, p = 0.11. EuroSCORE (6 vs. 3; p < 0.01), cardiopulmonary bypass time (90 vs. 71 min; p < 0.01), postoperative bleeding (450 vs. 350 ml; p < 0.01), postoperative atrial fibrillation (AF) (29 vs. 16%; p < 0.01), and inotropic support (58 vs. 31%; p = 0.001) were significantly different. These variables were entered into uni- and multivariate regression analysis. Postoperative AF (OR 1.76, p = 0.007) and EuroSCORE (OR 1.42, p < 0.01) were signifi cant risk factors predicting hospital mortality. Conclusions: Reoperative cardiac surgery can be performed under similar risks as primary operations. Postoperative AF and EuroSCORE are predictors of in-hospital mortality for redo cases.
