1. 1. Dietary fat as an exposure in epidemiological studies. Observations in the Malmö Diet and Cancer cohort

   Författare :Iréne Mattisson; Internmedicin - epidemiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Absolute fat; cohort study; confounders; energy-adjustment; fibre; food groups; plant food; prospective study; relative fat; underreporting; Public health; Näringslära; epidemiology; breast cancer; Folkhälsa; epidemiologi; Nutrition;

   Sammanfattning : The aim was to explore the inherent meaning of total fat and to examine the associations between relative fat intake and postmenopausal breast cancer. Furthermore, the impacts of the alterations in dietary assessment routines are discussed. This thesis uses data from the Malmö Diet and Cancer study, a prospective cohort study. LÄS MER

3. 2. Clinical and epidemiologic aspects of Rheumatoid Arthritis. Special emphasis on cardiovascular outcome and risk factors

   Författare :Ulf Bergström; Internmedicin - epidemiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rheumatoid arthritis; Cardiovascular disease and Risk factors;

   Sammanfattning : Rheumatoid arthritis (RA) is a systemic disease, with an increased risk of co-morbidity from cardiovascular disease (CVD), in particular among those with severe disease. Environmental risk factors are of potential interest for both prevention and treatment of RA. LÄS MER

4. 3. Cardiovascular disease and adrenergic dysfunction in mild primary hyperparathyroidism

   Författare :Mats Birgander; Internmedicin - epidemiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Primary Hyperparathyroidism; parathyroidectomy; parathyroid hormone; cardiovascular disease; mortality.;

   Sammanfattning : Primary hyperparathyroidism (PHPT) is associated with cardiovascular morbidity and premature death, but the underlying mechanisms are incompletely understood. The aim of this thesis was to investigate cardiovascular parameters and adrenergic function in mild PHPT compared to healthy controls subjects before and after curative parathyroidectomy (PTX).

5. 4. Absorbed Dose Determination and Characteristics of Degraded Electron Beams: Application to Intraoperative Radiation Therapy

   Författare :Peter Björk; Internmedicin - epidemiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; absorbed dose distribution; output factor; stopping-power ratio; beam characteristics; Monte Carlo calculation; electron beam dosimetry; applicator system; radiation therapy; linear accelerator; intraoperative radiotherapy;

   Sammanfattning : The aim of this work was to quantify limitations of and uncertainties in commonly used dosimetric techniques for relative absorbed dose determination in degraded electron beams, such as those encountered in intraoperative radiation therapy (IORT) and small-electron-field radiotherapy. Three different detector types were investigated with regard to measurements of output factors and relative absorbed dose distributions: (1) a parallel-plate ionization chamber, (2) a p-type silicon diode detector and (3) a diamond detector.

7. 5. Impact of renal dysfunction on serum Prostate-Specific Antigen

   Författare :Laila Bruun; Internmedicin - epidemiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urologi; hK2; Urology; intra-individual variation; elimination; peritoneal dialysis; renal dysfunction; kidney transplantation; hemodialysis; nefrologi; nephrology; PSA;

   Sammanfattning : Measurement of prostate-specific antigen (PSA) in blood is an important tool in detection for prostate cancer. PSA occurs in several molecular forms in blood: mainly as a free form with a molecular mass of 28 kDa; and as PSA complexed to alpha-1-antichymotrypsin, complexed PSA, with a molecular mass of 90 kDa.
