1. 16. Factors affecting body weight development and eating behaviour in patients on continuous ambulatory peritoneal dialysis treatment

   Sammanfattning : Continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis (HD) have different metabolic effects in dialysis patients, since absorption of intraperitoneal glucose implies an additional energy source in CAPD patients. In spite of this, protein-energy malnutrition is known to occur frequently, both in patients on hemodialysis and in patients on CAPD, and an association with increased morbidity and mortality is well established.

3. 17. Weight scaling : methods to determine the quantity of pulpwood

   Författare :Mikael Hultnäs; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Scaling pulpwood according to its weight for payment purposes is done in many places around the world. In North America, pulpwood is commonly scaled according to its green weight, while in Central Europe the wood is commonly scaled according to its dry weight. In Sweden pulpwood is measured according to its volume. LÄS MER

4. 18. Skeletal growth and effects of physical activity during adolescence

   Författare :Martin Sundberg; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Population-based; Physical activity; Longitudinal; Intervention; Growth; Adolescents; Bone mineral density; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

   Sammanfattning : The aim of this thesis was to evaluate bone mass and bone size in girls and boys from age 12 to 16, with special attention to physical activity. We also wanted to retrospectively evaluate the effect of exercise for the years preceding age 12. The findings were as follows. LÄS MER

5. 19. Rheumatoid Arthritis: Body Composition, Bone Loss, and Mortality

   Författare :Christina Book; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fat mass; bone mass; lean mass; body composition; mortality; rheumatoid arthritis; predictors;

   Sammanfattning : Early rheumatoid arthritis (RA) patients (disease duration ≤1 year, n=165) were recruited 1995-2001 and followed systematically clinically and with dual energy X-ray absorptiometry (DXA) over 2 years and compared to age- and gender-matched controls. Baseline arm and leg lean mass were decreased in RA patients in both genders and body mass index and truncal fat distribution were increased in female RA patients. LÄS MER

7. 20. The Influence of Physical Activity on Musculoskeletal Characteristics and Fracture Risk at Growth

   Författare :Fredrik Detter; Ortopedi - klinisk och molekylär osteoporosforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BMC; BMD; pQCT; DXA; Fractures; Children; Bone; Muscle;

   Sammanfattning : Physical Activity (PA) can improve neuromuscular development. A high level of physical activity can perhaps however lead to more fractures. This is a longitudinal population-based exercise intervention study where the school-based physical education (PE) in one school is increased from mean 60 min/week to mean 200 min/ week. LÄS MER
