1. 1. Human body composition. Reference data and anthropometric equations. The metabolic syndrome and risk

   Författare :Ingrid Larsson; Göteborgs universitet; []
   Nyckelord :adults; anthropometry; atherosclerotic morbidity; body composition; body fat; cardiovascular disease; DEXA; dual energy x-ray absorptiometry; fat-free mass; FFM; humans; metabolic syndrome; morbidity; mortality; prediction equations; randomly selected sample; reference data; sagittal trunk diameter; TBK; total body potassium; waist circumference;

   Sammanfattning : The determination of body composition is a key to the understanding of the relation between obesity and disease. In order to evaluate body composition data, reference values are needed. Since methods with high validity and reproducibility are expensive and often time consuming, simpler techniques based on anthropometry are needed. LÄS MER

3. 2. Anterior cruciate ligament reconstruction surgery, aspects of graft choice, graft fixation and bone mineral loss

   Författare :Sven Stener; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior cruciate ligament; Reconstruction; Revision; PLLA; Bone mineral areal mass; DEXA;

   Sammanfattning : The aim of this thesis was to measure bone mineral changes in the calcanei, hips and lumbar spine of patients reconstructed with bone-patellar tendon-bone (BPTB) or hamstring tendon (HT) autografts following anterior cruciate ligament (ACL) injury. Furthermore, the aim was to compare the clinical results after ACL revision reconstruction with either reharvested ipsilateral or contralateral BPTB autografts. LÄS MER

4. 3. Prediction of disease progression in early rheumatoid arthritis. A study of some imaging and laboratory variables

   Författare :Kristina Forslind; Lund Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rheumatology locomotion; Skelett; muskelsystem; reumatologi; muscle system; Skeleton; Rheumatoid arthritis; MRI; Reduced bone mass; Disease prediction; Anti-CCP; DEXA DXA;

   Sammanfattning : Objective: To investigate the role of magnetic resonance imaging (MRI), assessment of bone mineral density (BMD) and antibodies to citrullinated proteins (anti-CCP) in predicting radiologic outcome in patients with early rheumatoid arthritis (RA). Patients: All patients were included in the BARFOT programme (baseline). LÄS MER

5. 4. A clinical study of uncemented hip arthroplasty : radiological findings of host-bone reaction to the stem

   Författare :Henrik Bodén; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Arthroplasty; bone remodelling; DEXA; fixation; geometrical design; hydroxyapatite; osteoarthritis; scintigraphy; stem size; stress-shielding; tapered; titanium; uncemented; weight-bearing.;

   Sammanfattning : In total hip arthroplasty (THA), the main reason for failure leading to revision is aseptic loosening. Both mechanical and biological effects act in the loosening process, the factors may be implant design, fixation mode or technique, as well as biological factors unique to the individual. LÄS MER

7. 5. Assessment of Body Composition Using Magnetic Resonance Imaging

   Författare :Joel Kullberg; Hans Frimmel; Tomas Gustavsson; Uppsala universitet; []
   Nyckelord :Bildanalys; Magnetic Resonance Imaging; Digital Image Processing; Segmentation; Morphology; Body Composition; Whole Body Imaging; Subcutaneous Adipose Tissue; Visceral Adipose Tissue; Anthropometry; Bildanalys;

   Sammanfattning : Methods for assessment of body composition allow studies of the complex relationships between body composition and the wellbeing of humans. The amount and distribution of adipose tissue is of great importance in these studies. LÄS MER
