Item 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-5844-2020Coronary 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.Item Characteristics of Newly Diagnosed Hepatocellular Carcinoma Patients Across Turkey: Prospective Multicenter Observational 3K Registry Study(2021) Ozyilkan, Ozgur; 34876392Aims: 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.Item Impact of Platelet Count in Retinopathy of Prematurity(2020) Keskek, Nedime Sahinoglu; Gulcan, Hande; Yilmaz, Gursel; Akkoyun, Imren; 0000-0001-8544-103X; 33389935; T-4258-2017Objectives: 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.Item The impact of addressing modifiable risk factors to reduce the burden of cardiovascular disease in Turkey(2019) Balbay, Yucel; Gagnon-Arpin, Isabelle; Malhan, Simten; Oksuz, Mehmet Ergun; Sutherland, Greg; Dobrescu, Alexandru; Villa, Guillermo; Ertugul, Gulnihal; Habib, Modhar; 0000-0002-5723-5965; 31483303; K-8238-2012Objective: Our study aimed to estimate the impact of addressing modifiable risk factors on the future burden of cardiovascular diseases (CVD) in the general population and in two high-risk populations (heterozygous familial hypercholesterolemia and secondary prevention) for Turkey. Methods: One model investigated the impact of reaching the World Health Organization (WHO) voluntary targets for tobacco use, hypertension, type 2 diabetes, obesity and physical inactivity in the general population. Another model estimated the impact of reducing LDL-cholesterol in two high-risk populations through increased access to effective treatment. Inputs for the models include disease and risk factor prevalence rates, a population forecast, baseline CVD event rates, and treatment effectiveness, primarily derived from the published literature. Direct costs to the public health care system and indirect costs from lost production are included, although the cost of programs and pharmacological interventions to reduce risk factors were not considered. Results: The value of reaching WHO risk factor reduction targets is estimated at US$9.3 billion over the next 20 years, while the value of reducing LDL-cholesterol is estimated at up to US$8.1 billion for high-risk secondary prevention patients and US$691 million for heterozygous familial hypercholesterolemia patients. Conclusion: Efforts to achieve WHO risk factor targets and further lower LDL-cholesterol through increased access to treatment for high-risk patients are projected to greatly reduce the growing clinical and economic burden of CVD in Turkey.Item The risk factors, consequences, treatment, and importance of gestational depression(2015) Yilmaz, Elif Akkas; Gulumser, Cagri; 28913052Nowadays, mental problems have become an important health issue, the most frequent of which in pregnancy is depression. Gestational depression is known to increase gestational complications and negatively affect maternal and fetal health. The frequency of gestational depression and depressive symptoms are 10-30%. Risk factors vary according to genetic, psychologic, environmental, social, and biologic factors. Maternal morbidity and mortality rates increase in pregnant women who do not receive treatment, obstetric complications and negative fetal consequences are seen, and the incidence of postpartum depression increases. Due to all these important consequences, healthcare providers who manage pregnant women should be informed about the frequency, symptoms, and screening methods of postpartum depression, the significance of the consequences of undiagnosed and untreated depression on the health of mother and baby, and the importance of early diagnosis. Pregnant women who are at risk should be screened and detected, and directed to related centers. In this review, we briefly review the definition of gestational depression, its frequency, risk factors, complications, screening, treatments, and the procedures that need to be performed the diagnostic process.Item Predictors of in-hospital mortality following redo cardiac surgery: Single center experience(2015) Colkesen, Yucel; Coskun, Isa; Cayli, Murat; Gulcan, Oner; 26527452Purpose: 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.
