31. Survival and functional recovery following valve replacement in patients with severe aortic stenosis
Sammanfattning : Background: Aortic stenosis (AS) is the most common heart valve disease in Europe and North America. Age-related calcification of the valve is the commonest cause of acquired AS, especially in patients older than 70 years. LÄS MER
32. Neural Network Approaches To Survival Analysis
Sammanfattning : Predicting the probable survival for a patient can be very challenging for many diseases. In many forms of cancer, the choice of treatment can be directly impacted by the estimated risk for the patient. This thesis explores different methods to predict the patient's survival chances using artificial neural networks (ANN). LÄS MER
33. Cancer of the Colon and Rectum : Population Based Survival Analysis and Study on Adverse Effects of Radiation Therapy for Rectal Cancer
Sammanfattning : The Swedish Cancer Register was used to determine the relative survival rate in colon and rectal cancer and to estimate the occurrence of second cancers related to radiation therapy for rectal cancer. The Swedish Hospital Discharge Register and hospital records were used to estimate the rate of late adverse effects due to radiation therapy for rectal cancer. LÄS MER
34. Bystander CPR : New aspects of CPR training among students and the importance of bystander education level on survival
Sammanfattning : Background: It has been proved that bystander cardiopulmonary resuscitation (CPR) saves lives; however, which training method in CPR is most instructive and whether survival is affected by the training level of the bystander have not yet been fully described. Aim: To identify the factors that may affect 7th grade students’ acquisition of CPR skills during CPR training and their willingness to act, and to describe 30-day survival from outof- hospital cardiac arrest (OHCA) after bystander CPR and the actions performed by laymen versus off-duty medically educated personnel.

35. Aortic Valve Replacement: The Influence of Prosthesis-Patient Mismatch for Left Ventricular Remodeling, Cardiac Function and Survival
Sammanfattning : The best valve substitute for aortic valve replacement (AVR) in terms of hemodynamic performance, durability, incidence of complications, and survival remains the subject of much debate. It has been suggested that valve performance is influenced by the potentially modifiable variable prosthesis-patient mismatch (PPM). LÄS MER
