   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Dupuytren´s contracture; epidemiology; outcome study; cohort; prognostic factors; immunohistochemistry; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Sammanfattning : Dupuytren's contracture (DC) is a fibromatous disease of the palmar fascia of unknown etiology. The present study was undertaken in order to assess pathophysiological mechanisms and consequences. In a cohort study of 2,375 patients operated for DC at the Department of Hand Surgery, Uppsala there was a male: female ratio of 5.9:1. LÄS MER

5. 9. Metabolomics, body composition and fracture

   Författare :Rui Zheng; Karl Michaëlsson; Harri Sievänen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Metabolomics; LC-MS; sample quality; cohort; body composition; fracture; Medicinsk vetenskap; Medical Science; Bioinformatics; Bioinformatik; Epidemiologi; Epidemiology; Orthopaedics; Ortopedi; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

   Sammanfattning : In this thesis, I evaluated the impact of pre-centrifugation sample management on the plasma metabolome, providing verification for the protocol used in a study where I applied metabolomics to better understand the role of body composition in fracture occurrence using a large population-based cohort.  In paper 1, I applied untargeted liquid chromatography-mass spectrometry (LC-MS) metabolomics analysis to plasma samples (n = 471) from healthy donors to predict and evaluate the effect of pre-centrifugation temperature and delay time on metabolomics data using a combination of random forest and generalized linear models.

7. 10. Epidemiological studies on type 2 diabetes : assessment of diabetes risk factors and study participation

   Författare :Anna-Karin Eriksson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :cohort;

   Sammanfattning : Type 2 diabetes is a disease with increasing prevalence. Better knowledge of risk factors may form the bases for specific interventions and preventive measures. The aim of this thesis was to contribute to the knowledge on type 2 diabetes, by examining family history of diabetes and other risk factors with emphasis on psychological exposures. LÄS MER
