      <p><i>Background</i>: Serum osteoprotegerin (OPG) is elevated in patients with chronic kidney disease (CKD) and increases with decreasing renal function. However, there are limited data regarding the association between OPG and renal function in the general population. The aim of the present study was to explore the relation between serum OPG and renal function in subjects recruited from the general ...
    • Serum osteoprotegerin levels are related to height loss : the Tromsø Study 

      Jørgensen, Lone; Hansen, John-Bjarne; Brox, Jan; Mathiesen, Ellisiv B.; Vik, Anders; Jacobsen, Bjarne Koster (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Severe loss of body height is often a consequence of osteoporotic vertebral fractures. Osteoprotegerin (OPG) and receptor activator of nuclear factor-kB ligand (RANKL) are cytokines essential for the regulation of bone resorption. The aim of this study was to assess the relationship between the OPG/RANKL system and height loss. A total of 4,435 inhabitants from the municipality of Tromsø, ...
    • Study protocol : an early intervention program to improve motor outcome in preterm infants : a randomized controlled trial and a qualitative study of physiotherapy performance and parental experiences 

      Øberg, Gunn Kristin; Campbell, Suzann K; Girolami, Gay L; Ustad, Tordis; Jørgensen, Lone; Kaaresen, Per Ivar (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Background Knowledge about early physiotherapy to preterm infants is sparse, given the risk of delayed motor development and cerebral palsy. Methods/Design A pragmatic randomized controlled study has been designed to assess the effect of a preventative physiotherapy program carried out in the neonatal intensive care unit. Moreover, a qualitative study is carried out to assess the physiotherapy ...
