Definition Vena cava’s superior syndrome (VKSS), right vena cava superior (VKS) Clinical findings due to obstruction in atrial discharge and The name given to the group of symptoms. Anatomy and Physiology of superior vena cava syndrome. Vena kava is responsible for venous drainage of superior head, neck, arms and upper thorax and the heart performs a third of the venous conversion. A thin-walled vein for lung and mediastinum (especially to the mid-median line of the anterior mediastinum) It is very sensitive to the pressure of existing lesions. In the obstructive VKS itself, it may be in the big veins vacated in the VCS or in the place where the VCS vacates. Obstruction may be caused by external pressure, intravascular (tumor, thrombus may also occur due to pathologies. Whatever the reason, at VKS Obstruction increases pressure on the venous line, causing a reverse flow. Vena cava super superior obstruction, especially azygous venous system and vena cava inferior to the development of venous collateral circulation opens. Vena kava superior causes acute obstruction of cardiac output temporarily It happens. But within hours, the situation is compensated by collateral circulation. Collateral the veins become dilated within a few weeks and the pressure rising in the upper half of body. It shows a significant fall. This fall is temporary, when the event becomes permanent, over time In the etiology ofVKSS, which was formerly caused by infectious causes such as syphilis and berculosis malignant tumors have been seen more frequently for about 25 years. Responsible for 60-85% of patients with VKSS. More recently than in the past Port catheters used, intravascular devices such as heart valves and implanted defibrillators due to thrombotic complications due to devices (> 30%) increase in VKSS It is monitored. Etiological reasons are summarized. Malignancy is unknown in 60% of cases with malignant VCSF and the first findings are thought to be related to VKSS. Non-small cell lung- Cancer (NSCLC) is the most common cause of VKSS. Her small-cell lung cancer (KHAK). The incidence of non-Hodgkin lymphoma is 10%. Malignant VKSS 95% of the cases consist of lung cancer and non-Hodgkin’s lymphoma patients. Vena Kava Superior Syndrome in Lung Cancer When all lung cancer cases are examined, approximately 4%. In small cell lung cancer, central and mediastinal lymph node involvement , this rate is over 10%. The tumor is located in the upper right lobe or When the mediastina is localized, VKSS develops more frequently due to anatomic proximity (10-15%). In lung cancer, VKSS… Read More »
The formation and properties of a metallic bond. In order for a bond to form, atoms must be more stable (with less energy) than they once were. To summarize, when the bonds are formed, they give energy to the outside. When atoms bond, they try to match their electron arrangement to noble gases. The number… Read More »

What is the data warehouse? First, it should be known that data warehouse is not a program or product. The data warehouse is an architecture that is a medium. The data warehouse is a repository for collectors and historical data in an understandable and easily accessible structure after receiving, cleaning and replacing data from different operational systems, call centers and similar sources. In other words, data warehouse is a relational database designed to be used for querying and analysis rather than database movement. In general, it may include historical information from motion data, as well as information from other sources. With the workload of database movement, the analysis distinguishes the burden from each other, allowing the information gathered from different sources to be organized more easily. As I mentioned above, the information to be transferred to the data warehouse passes through a number of operations before being transferred to the data warehouse. The data passes through the ETL process before entering the data warehouse. In this way, depending on how to use the given data, the desired format is inserted. Solutions So what is this ETL? First, let’s look at the opening of the ETL. ETL; Extract: Receiving data from the source system, Transform: The data have to go through certain transformations in order to be appropriate for our production. That is to say, cleaning and improving the quality of a certain kind, Load: means that the data is loaded into the target system. ETL in brief; the data is retrieved from the source system, changed accordingly, and loaded into the data warehouse. Another data quality method is ELT. ELT (Extract Load Transform) is; the data is again taken from the source system, but this time the transform is performed after loading into the system. ELTA With these transactions, Data Cleaning, Data Conforming, It’s called Data Quality. So why is the quality of the data warehouse so important? If the data in the data warehouse were very irregular and were in a situation where it was not possible to operate on the allele, we could get wrong results in our queries. For example; When we want to choose unmarried women over 18, the data in the gender block are female, female, May be entered in shapes. In this case, we will have lost a significant amount of future data when we take our inquiry as a lady.… Read More »
