1. 6. Homocysteine and its determinants in relation to cardiovascular risk factors and myocardial infarction

   Författare :Elisabet Söderström; Johan Hultdin; Torbjörn K. Nilsson; Anders Larsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Homocysteine; folate; myocardial infarction; apolipoprotein; risk factors; cotinine; nicotine; tobacco; CTH; MTHFR; renal insufficiency; glomerular filtration rate; creatinine; cystatin C; shrunken pore syndrome; epidemiology; Clinical Chemistry; klinisk kemi;

   Sammanfattning : Background: Globally, cardiovascular diseases (CVD), including myocardial infarction (MI) and stroke, are the leading cause of illness and death and constitute a significant part of the disease burden in Sweden and Western Europe. Age, hypertension, smoking, obesity, dyslipoproteinemia, diabetes, and impaired renal function are considered established risk factors for CVD. LÄS MER

3. 7. Work Environment in the Operating Room during Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy : Factors Influencing Choice of Protective Equipment

   Författare :Sara Näslund Andréasson; Haile Mahteme; Helena Anundi; Christine Leo Swenne; Ulrica Nilsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Peritoneal carcinomatosis (PC) is a common metastatic manifestation of both gastrointestinal and gynecological malignancies. Curative modes of treatment are cytoreductive surgery (CRS) combined with intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC). LÄS MER

4. 8. Inflammatory bowel disease in twins : studies of genetics and environmental factors

   Författare :Jonas Halfvarson; Salvador Peña; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The aetiology of inflammatory bowel disease (IBD) is unknown but considered to be caused by interplay of genetic and environmental factors.The aims of this thesis were to study the influence of genetics and environmental factors in aetiology, disease phenotype and levels of Anti-Saccharomyces cerevisiae antibodies (ASCA), as well as to assess whether CARD15/NOD2 polymorphisms explain the influence of genetics in these aspects.

5. 9. Bayesian Inference with Unknown Noise Covariance

   Författare :Lennart Svensson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis studies Bayesian methods in statistical signal processing. A central theme is that the treatment of the unknown noise covariance matrix is of chief concern for all scenarios. As a first application, the detection of land mines using infrared techniques is investigated. LÄS MER

7. 10. Comorbidity and vascular risk factors  associated with idiopathic normal pressure hydrocephalus : the INPH-CRasH Study

   Författare :Hanna Israelsson Larsen; Jan Malm; Anders Eklund; Norman Relkin; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hydrocephalus; normal pressure; vascular disease; vascular risk factors; elderly; depression; case control study; epidemiology; dementia; vascular dementia; small vessel disease; cerebrovascular disease; transient ischemic attack; Neurology; neurologi;

   Sammanfattning : Idiopathic normal pressure hydrocephalus (INPH) is a dementia treatable by insertion of a cerebrospinal fluid shunt. It has been suggested that INPH has similar pathophysiological mechanisms as cerebrovascular disease, but the vascular risk factor (VRF) profile of INPH patients has not been assessed using a modern epidemiological approach.
