Validation of repeated self-reported n-3 PUFA intake using serum phospholipid fatty acids as a biomarker in breast cancer patients during treatment.

Background: The role of n-3 polyunsaturated fatty acids (PUFAs) in breast cancer is not clear and under debate. To explore this relationship it is important to have proper validated dietary assessment methods for measuring the intake of n-3 PUFAs. The aim of the current study is to validate two different methods used to assess the intake of selected n-3 PUFAs as well as food sources of long-chained n-3 PUFAs.

Trans-fatty Acids and Survival in Renal Transplantation.

Objective: High consumption of trans-fatty acids (TFAs) is associated with increased mortality.

Design And Methods: Observational cohort study of 1.988 Norwegian renal transplant recipients with a median follow-up time of 9.

Serum levels of leptin and adiponectin are not associated with disease activity or treatment response in multiple sclerosis.

Adipokines secreted by fatty tissue have inflammatory properties and are suggested biomarkers of MS disease activity. To assess this, 88 MS patients were followed with nine repeated measurements of leptin and adiponectin and 12 magnetic resonance imaging (MRI) scans for two years; six months without any immunomodulatory treatment followed by 18 months during interferon-beta (IFNB) treatment. Serum levels of leptin dropped and adiponectin increased upon initiation of IFNB-therapy, but were not associated with clinical or MRI disease activity or with treatment response.

α-Linolenic acid is associated with MRI activity in a prospective cohort of multiple sclerosis patients.

Background: The plant-based ω-3 fatty acid α-linolenic acid (ALA) has been associated with lower MS risk. It is currently unknown whether ALA affects disease activity.

Objective: To investigate the association between ALA levels and disease activity.

Development of Kidney Transplant Fibrosis Is Inversely Associated With Plasma Marine Fatty Acid Level.

Objective(s): We assessed associations between plasma levels of polyunsaturated fatty acids (PUFAs) and degree of inflammation and interstitial fibrosis in transplanted kidneys.

Design: The design of the study was single center cohort study.

Subjects: A study population of 156 patients who received a kidney transplant at Oslo University Hospital during 2010.
