1. 6. Boning up on Vitamin D : Observational Studies on Bone and Health

   Författare :Greta Snellman; Karl Michaëlsson; Haakon Meyer; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vitamin D; fracture; BMD; assays; genes; mortality; cohort studies; Orthopaedics; Ortopedi;

   Sammanfattning : The primary function of vitamin D in humans is to maintain sufficient circulating calcium concentrations. Low vitamin D levels could result in excessive calcium resorption from bone. Vitamin deficiency may therefore decrease bone mineral density (BMD), resulting in an increased risk of fracture. LÄS MER

4. 8. Vitamin D deficiency in Northern Sweden : a cross-sectional study of an immigrant population at latitude 63° N, including an open partially randomized, controlled trial studying the effect of supplementation with different doses of cholecalciferol

   Författare :Lena Granlund; Eva Fhärm; Christer Andersson; Marie Lindkvist; Anna Ramnemark; Ingrid B Bergström; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vitamin D deficiency; 25-hydroxyvitamin D; cross-sectional study; immigrant; muscle strength; grip strength; anxiety; depression; health related quality of life; clinical trial; cholecalciferol; family medicine; allmänmedicin;

   Sammanfattning : Background: Vitamin D is a prohormone that plays a key role in the calcium and phosphate balance and has physiological functions throughout the entire body. Vitamin D is supplied by exposure to ultraviolet light or by food. The prevalence of vitamin D deficiency in immigrants in Northern Sweden was unknown. LÄS MER

5. 9. Vitamin D, muscle strength, prolonged labour, Caesarean sections and lifestyle : Clinical and intervention studies in pregnant Somali and Swedish women and new mothers

   Författare :Paul Kalliokoski; Monica Löfvander; Maria Bullarbo; Uppsala universitet; []
   Nyckelord :: caesarean section; dystocia; immigrant; muscle strength; obstetric labour complications; osteomalacia; physical performance; Somalia; vitamin D; vitamin D deficiency; Family Medicine; Allmänmedicin;

   Sammanfattning : Long-term severe vitamin D deficiency may cause osteomalacia with muscle weakness, pain, soft bones, cramps and eventually death. In a pilot study, I found many Somali women to be vitamin D deficient and very weak. LÄS MER

7. 10. The Role of Fibroblast Growth Factor 23 in Phosphate Homeostasis

   Författare :Tobias Erik Martin Larsson; Kenneth Jonsson; Östen Ljunggren; Suzanne Jan De Beur; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Fibroblast Growth Factor 23; FGF-23; phosphate homeostasis; vitamin D metabolism; sodium phosphate cotransporters; autosomal dominant hypophosphatemic rickets; ADHR; X-linked hypophosphatemic rickets; XLH; oncogenic osteomalacia; OOM; PHEX; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

   Sammanfattning : The regulation of serum phosphate (Pi) concentrations is a complex process and our current models are far from complete. Due to major advancements in biotechnology and the development of more powerful research tools, recent advances in the field of genetics has led to the identification of several candidates for the long sought-after phosphatonin(s), or Pi regulating hormones.
