1. 16. Background Studies for the Balloon-Borne Hard X-ray Polarimeter PoGOLite

   Författare :Merlin Kole; Mark Pearce; Petteri Nieminen; KTH; []
   Nyckelord :Fysik; Physics;

   Sammanfattning : The polarisation degree and angle of the X-ray flux emitted by astrophysical objects holds valuable information on the responsible emission mechanisms and on the emission environments. PoGOLite is a balloon-borne hard X-ray polarimeter designed to measure polarisation using a segmented plastic scintillator array. LÄS MER

4. 18. Outcome and risk factors after aortic valve interventions

   Författare :Per Kvidal; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; aortic valve replacement; mechanical valve prosthesis; relative survival; morbidity; recurrent events; balloon aortic valvuloplasty; long-term follow-up; Kirurgi; Surgery; Kirurgi; kardiologi; Cardiology;

   Sammanfattning : In the present study the long-term survival and morbidity and the associated risk factors after aortic valve replacement (AVR) and after aortic balloon valvuloplasty were evaluated. In a cohort of 2,359 consecutive patients undergoing primary aortic valve replacement, the early mortality was 5.6%. LÄS MER

5. 19. Early detection of major surgical postoperative complications evaluated by microdialysis

   Författare :Tal Hörer; Kjell Janson; Lars Norgren; Bengt Jeppsson; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aortic occlusion balloon; anastomotic leakage; glycerol; intraabdominal hypertension; intraperitoneal microdialysis; intestinal ischemia; intraabdominal metabolism; lactate pyruvate ratio; postoperative complications; ruptured abdominal aortic anerusym; Kirurgi; Surgery;

   Sammanfattning : Major abdominal surgery may be followed by postoperative complications, especially in the elderly and patients with co morbidities as diabetes mellitus and obesity. Some of the most feared complications as anastomotic leakage, abdominal infections, abdominal compartment syndrome (ACS) and intestinal ischemia can lead to sepsis, systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS) with high morbidity and mortality.

7. 20. Endovascular occlusion methods in non-traumatic cardiac arrest

   Författare :Emanuel M. Dogan; Tal M. Hörer; Kristofer F. Nilsson; Birger Axelsson; Lars Wik; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac arrest; cardiopulmonary resuscitation; REBOA; intra-aortic balloon pump;

   Sammanfattning : Approximately 10% of out-of-hospital cardiac arrest patients survive to hospital discharge. An important factor for survival is perfusion to the coronary and cerebral circulations during cardiopulmonary resuscitation (CPR). LÄS MER
