Endovascular treatment of acute type B dissection complicating graft-bypass repair for aortic coarctation

AbstractObjectivesThe early dissection of the descending aorta after the repair of aortic coarctation is very rare. Herein, we present a special endovascular technique used for acute type B dissection complicating graft bypass for aortic coarctation.MethodsThe 48 year-old male patient with the diagnosis of adult type aortic coarctation had bypass procedure between the aortic arch and the descending aorta. Six weeks after the first operation, the patient was readmitted with severe back pain and had the diagnosis of acute type B dissection which involved the descending aorta at the distal part of the graft anastomosis.ResultsTwo separate stent-grafts were deployed respectively 31 × 150 mm and 34 × 200 mm (C-TAG™ WL Gore&Asc., Flagstaff, AZ, USA). The previous Dacron bypass graft was used as a proximal landing zone for the first stent-graft. The distal landing zone for the second stent was the area between the celiac trunk and superior mesenteric artery. Therefore, the covered stent-graft was implanted to the celiac trunk (Viabahn™ 7 × 50 mm WL Gore&Asc, AZ, USA) to maintain its patency before the deployment of the second graft. The segment of coarctation was closed with a vascular plug (Amplatzer™ vascular plug II) to prevent persistent perfusion of aneurysmal false lumen.ConclusionThe endovascular approach offers multiple less invasive options based on a patient-specific problem

International migration in the framework of neoclassical macro migration theory: An analysis of the countries receiving the most immigration

Uluslararası göç teorileri genel anlamda geliştirilen ilk teoriden itibaren emek göçü üzerine odaklanmaktadır. Bu teorilere göre göçmen akışı ekonomik sistem içinde bir emek arzı oluşturmaktadır. Oluşan bu emek arzı emek talebini de beraberinde getirmektedir. Göç teorileri ülkeler arasındaki ücret düzeyi farklılıkları, gelir farklılıkları, istihdam imkanları göçü harekete geçiren önemli unsurlar üzerinde durmaktadır. Ülkeler arasındaki ekonomik farklılıklardan hareketle bu çalışma Uluslararası Göç Enstitüsüne göre en çok göç alan ülkelerin göç alma faktörlerini Neo-klasik Makro Göç Teorisi çerçevesinde ele almaktadır. Çalışma 1990-2017 dönemini kapsamaktadır. Heterojen panel nedensellik testi olan Dumitrescu-Hurlin nedensellik testinden faydalanılmıştır. Uygulama sonucunda elde edilen bulgulara göre göçün, kişi başı GSYİH, istihdam oranları ve ortalama yıllık ücret ile arasında çift yönlü bir nedenselliğin varlığı tespit edilmiştir.International migration theories generally focus on labor migration from the first theory developed. According to these theories, the flow of immigrants creates a labor supply within the economic system. This labor supply brings along the demand for labor. Migration theories focus on the differences in wage levels, income differences, employment opportunities among the countries that are important factors that motivate migration. Based on the economic differences between the countries, this study deals with the immigration factors of the countries that receive the most immigration according to the International Migration Institute within the framework of the Neo-classical Macro Migration Theory. The study includes annual data for the period 1990-2017. Dumitrescu Hurlin causality test, which is a heterogeneous panel causality test, was used. According to the findings obtained as a result of the application, it has been determined that there is a bidirectional causality between migration, GDP per capita, employment rates and average annual wage

Plasma profile of Pregnancy Associated Glycoproteins during Postpartum period in Konya Merino ewes lambing single and twin

This study investigated the plasma profile of Pregnancy Associated Glycoproteins (PAGs) after lambing in Konya Merino ewes using specific cattle pregnancy test kit. A total of 16 Konya Merino ewes were used as a material. Four groups were set up, ewes birthing a male lamb (SM group, n=4), a female lamb (SF group, n=4), twin male lambs (TM group, n=4) or twin female lambs (TF group, n=4). Blood plasma samples were taken on days 0 (lambing day), 3, 7, 10, 14 and then weekly until day 35. All samples were analysed using a bovine pregnancy test kit to detect of PAGs level. It was determined that there was a strong negative correlation between PAGs levels in peripheral blood and days after lambing (r2=0.969; P<0.01). However, no relationship was found between PAGs level and lamb gender or birth type. In conclusion, plasma PAGs level decreases rapidly in Konya Merino ewes regardless of lamb gender and birth type. Moreover, the results showed that the plasma profile of PAGs after lambing in Konya Merino ewes can be monitored with a bovine commercial ELISA–based pregnancy test kit, and the test results can be used in decisions and assessments based on the levels of PAG molecules

The impact of emigration and basic macroeconomic variables on employment: An analysis on nafta countries

Göç olgusu, son dönemde sosyologların olduğu kadar ekonomistlerin de ilgi alanı haline gelmiştir. İktisat biliminde çalışma alanı oluşturan göç konusu ile ilgili çalışmalar, literatüre çoğunlukla ampirik olarak katkıda bulunmaktadır. Bu çalışmada göç, istihdam, gayrisafi yurtiçi hâsıla ve tüketici fiyat endeksi gibi makro değişkenler arasındaki ilişki araştırılmaktadır. Bu bağlamda ekonomik imkânları, istihdam potansiyeli, yüksek ücretle çalışabilme olanağı ile nihai hedef ülke grubu olan NAFTA (Kuzey Amerika Serbest Ticaret Anlaşması) (Amerika Birleşik Devletleri, Kanada, Meksika) 1997-2017 dönemi yıllık verileriyle incelenmiştir. Panel veri analizinden faydalanılarak göç ve makro değişkenler ilişkisi istihdam araştırılmıştır. Dolayısı ile uluslararası göçün hedef ülkedeki seçilmiş makro değişkenlere etkisi araştırılmıştır. Ampirik uygulama sonucuna göre değişkenler arasında anlamlı ilişkiler bulunmaktadır. Göçte medya gelen %1’lik bir artış istihdam oranını %0,33 oranında artırmaktadır. Ampirik uygulamalar ile desteklenen sonuca göre göç akışlarının sadece problemli bir sosyolojik olgu olarak değerlendirilmemesi gerektiği görülmektedir. Kontrol edilmesi zor olan göç akışlarının doğru yönlendirildiğinde olumsuz etkilerinin olumlu sonuçlara dönüşebileceği yapılan çalışmalar ile desteklenmektedir. Küresel bir dünya da ve içinde bulunduğumuz bilgi çağı göç hareketinin her dönem dinamizmini koruyacağını ve iktisat bilimi içinde çalışma alanının daha da genişleyeceğini söyleyebiliriz.The phenomenon of migration has become an interest of economists as well as sociologists in recent times. Studies on migration, which constitutes a field of study in economics science, often contribute to the literature empirically. In this study, the relationship between macro variables such as migration, employment, gross domestic product and consumer price index is investigated. In this context, its economic opportunities, employment potential, high-wage ability, and the ultimate target country group, NAFTA (United States, Canada, Mexico), were examined with annual data from the period 1997-2017. The relationship of migration and macro variables was investigated by using panel data analysis. Therefore, the impact of international migration on selected macro variables in the target country has been investigated. According to the result of empirical application, there are significant relationships between variables. An increase of 1% in immigration from the media increases the employment rate by 0.33%. According to the result supported by empirical applications, it is observed that migration flows should not be considered as a problematic sociological phenomenon. It is supported by studies that negative effects of migration flows, which are difficult to control, can turn into positive results when directed correctly. We can say that the migration movement in a global world and the information age we are in will preserve the dynamism of each term and the field of study in economic science will expand further

Chimney technique for solitary pelvic kidney

BOZKAYA, HALIL/0000-0002-5012-6635WOS:000593040200029PubMed: 32888009The combination of solitary pelvic kidney and abdominal aortic aneurysm is extremely rare. in this report, we present chimney graft implantation in a patient with solitary pelvic kidney. A 63-year-old man had the diagnosis of infrarenal abdominal aortic aneurysm made incidentally. Preoperative computed tomography illustrated a fusiform abdominal aortic aneurysm accompanying a solitary ectopic kidney in the pelvis with aberrant renal artery. A bifurcated endograft was implanted, and a covered stent graft was placed into the renal artery by use of the chimney technique. Good patency of the chimney graft was documented with early postoperative and first month scans. To the best of our knowledge, this is the first report of the chimney technique used in a solitary pelvic kidney

Thoracic endovascular aortic repair for acute pathologies of descending thoracic aorta

WOS: 000314377200007Background: This study aims to analyze early and midterm results of thoracic endovascular aortic repair performed in acute pathologies of descending aorta. Methods: Between September 2006 and April 2010, 25 patients (21 males, 4 females; mean age 62.1 +/- 14.8 years; range 26 to 82 years) with acute aortic syndrome who underwent emergent surgery in our clinic through endovascular approach were included in this study. Demographic characteristics, preoperative and postoperative data were analyzed retrospectively by means of file scanning method. Results: The procedure was successful in all patients. A total of 29 thoracic endograft were implanted in 25 patients. Three patients (12%) died before hospital discharge. Major complications of this procedure including neurologic event and type 1 endoleaks were not observed in any patient. The mean follow-up was 20.2 +/- 16.8 months. During this period, none of the patients had need procedure-related complications, while only one patient treated for penetrating atherosclerotic ulcer died at 20 months due to malignancy. Conclusion: Although our study was designed retrospectively with a small sample size, we detected low morbidity and mortality rates. These results are consistent with the literature, however further studies reflecting the long-term safety results are required. Thoracic endovascular aortic repair is a feasible option of treatment for acute pathologies of descending thoracic aorta
