The factors that affect plasma homocysteine levels, pulse wave velocity and their relationship with cardiovascular disease indicators in peritoneal dialysis patients
Objective The incidence of cardiovascular diseases
(CVD) is high in end-stage renal disease (ESRD)
population and hyperhomocysteinemia is an important
CVD risk factor. The aims of this study are to
asses the incidence of hyperhomocysteinemia and the
factors that affect the homocysteine (Hcy) levels in
peritoneal dialysis (PD) patients, and to analyze the
relationships between Hcy levels and clinical and
echocardiographic CVD, and the pulse wave velocity
(PWV).
Study design Sixty ESRD patients undergoing PD
for at least 6 months were included in the study.
Biochemical parameters, echocardiography, and PWV
were analysed for every subject.
Results Mean Hcy level was 27.2 ± 15.7 lmol/L
and was high in 53 patients (88.3%). Fibrinogen,
dialysate/plasma creatinine ratio and folic acid were
found to be the independent predictors of Hcy level
(P\0.001; P\0.01; P\0.05, respectively).
Patients with atherosclerosis had significantly higher
plasma Hcy levels (P\0.05). No significant relationship
was found between plasma Hcy levels and
echocardiographic findings and PWV.
Conclusion Hyperhomocysteinemia incidence seems
high among PD patients and despite significant relationship
between fibrinogen and Hcy in our study, it is
essential to evaluate the link between Hcy levels and
inflammation. Folic acid replacement even in normal
folic acid levels, enough elimination of volume and
solutesmay be beneficial to control Hcy levels, whereas
PWV was found to be related with comorbidities and
and dialysate kinetics
RELATIVE EFFICIENCY ANALYSIS OF BLACK SEA CONTAINER TERMINALS
Dünyada yük taşımacılığı en fazla denizyolu ile yapılmaktadır. Denizyolu taşımacılığı içerisinde konteyner taşımacılığının oranı sürekli artış göstermektedir. Diğer denizyolu taşımacılık sistemlerinde olduğu gibi konteyner taşımacılığında da limanlar arasında yoğun bir rekabet vardır. Bu nedenle limanların bu yoğun rekabet ortamında faaliyet gösterebilmeleri için, yapılan işin doğası gereği sadece ulusal değil uluslararası standartlarda iş yapabilmeleri ve uluslararası geçerliliği olan performans göstergelerine sahip olmaları gereklidir. Bu çalışmada; Karadeniz çevresinde konteyner taşımacılığına hizmet veren ve TRACECA programı çerçevesinde Karadeniz'de faaliyet gösteren 5 ülke (Türkiye, Gürcistan, Ukrayna, BulgaristanveRomanya) ve program dışında bulunan Rusya'ya ait toplam 9 konteyner terminali (Novorossisk, Odesa, Varna, Burgaz, Batum, Poti, Ilyichevsk, Köstenceve Trabzon) 2011 yıl göreceli etkinlikleri parametrik olmayan Veri Zarflama Analizi (VZA) uygulaması ile belirlenmiştir. VZA sonuçlarına göre, incelenen terminaller içerisinde Poti ve Novorossisk konteyner terminali göreceli etkin durumdadır. Diğer yandan, en düşük göreceli etkinliğe sahip olan terminal ise Burgaz konteyner terminalidir Most of the world's freight transportation is made by maritime transportation. The proportion of container transportation within maritime transportation shows a constant increase. As it is the case for other maritime transportation systems, also in container transportation there is an intense competition among ports. For that matter, it is essential for the ports to have the internationally acceptable minimum performance indicators and to be capable of performing not only at national, but also at international standards by the nature of the work done, in order to continue operation under such intense competition conditions. In this study, the year performance, 2011 of nine container terminals (Novorossiysk, Odessa, Varna, Burgas, Batumi, Poti, Ilyichevsk, Constanta and Trabzon) belonging to a total of six countries with coastlines to the Black Sea, which is the largest inland sea, as five countries from the TRACECA (Transport Corridor Europe-Caucasus-Asia) program (Turkey, Georgia, Ukraine, Bulgaria and Romania) and Russia out of the program, have been determined through the application of data envelopment analysis (DEA), as a non-parametric method. According to the results of the study, it has been determined that the Poti and Novorossiysk container terminals have been the efficient terminals. On the other hand, Burgas container terminal has been found out to be the terminal with the lowest performance

Current Status of Kidney Replacement Therapy in Türkiye: A Summary of 2021 Turkish Society of Nephrology Registry Report
Objective: Turkish Society of Nephrology registry collects data on hemodialysis, peritoneal dialysis, and transplantation annually. Registry reports are printed every year as a booklet, and this is the 32nd year of registry reports. The registry is in close collaboration with international registries. Methods: In this paper, we summarized data from the 2021 registry report and provided yearly trends for managing end stage kidney disease. Results: The number of patients on kidney replacement therapy increases; at the end of 2021, 84 128 patients were on kidney replacement therapy. The prevalence and incidence of end-stage kidney disease were 993.5 and 149.5 per million population, respectively. Diabetes was the most common cause of end-stage kidney disease. Hemodialysis (71.4%) was the most common type of treatment modality, followed by transplantation (24.6%) and peritoneal dialysis (4.0%). Conclusion: End-stage kidney disease is a critical and growing health problem for our country. The kidney registry of the Turkish Society of Nephrology is one of the leading tools for providing current and sound data on this public health problem
