Background: Iodine nutrition relies on dietary intake. Marine foods are iodine rich, and they contributed markedly to the iodine intake among populations in Greenland. However, dietary habits are drifting away from the traditional diet dominated by iodine rich marine foods such as seal, whale, and seabirds. This led us to monitor iodine nutrition among populations in Greenland.Methods: Cohort studies were conducted in 1998, 2008, and 2018 including 50-69...

Background: High oxidative stress is associated with increased morbidity. The effect of testosterone treatment (TT) on oxidative stress in ageing men with reduced bioavailable testosterone is undetermined.Aim: To determine the effect of TT compared to placebo on oxidative stress biomarkers.Methods: Double-blinded, placebo-controlled study in 38 men, aged 60–78 years, with bioavailable testosterone <7.3 nmol/l and waist cir...

Introduction: Iodine deficiency is a significant global health issue of various severity depending on the age of the deficiency. The foetal period is the most critical stage in life, negatively impacting the brain and neurodevelopment. Hence, the developing foetus is a crucial issue, and the present study focussed on iodine nutrition among pregnant women from the Faroe Islands. The need for iodine increases in pregnancy, and the recommended target for median urinary iodine con...

Metabolic diseases are among the most important diseases in western societies and usually related to obesity. Dietary interventions are recommended for treatment and include both strategies with reduced caloric intake and alterations in macronutrient composition. Metabolism must be assumed to be regulated differently in females and males. In previous studies we demonstrated that low carbohydrate high fat (LCHF) diets affect GH/IGF-I axis in male rats. We know investigated whet...

Introduction: The osteoblast derived bone formation marker osteocalcin has been reported to decrease adipose tissue in mice. In elderly men, osteocalcin was reported to correlate inversely with fat mass.Aim: To examine the relationship between osteocalcin and regional fat depots.Method: The Odense Androgen Study is a population-based, cross-sectional study of 779 randomly selected men aged 20–29 years. Total, central, upper ex...

Objective: To study HbA1c as a tool for diagnosing diabetes and to study HbA1c as a cardiovascular risk marker in patients with polycystic ovary syndrome (PCOS).Methods: A retrospective observational study at an academic tertiary-care medical center. In total, 208 premenopausal women with PCOS participated. Patients underwent clinical evaluation (Ferriman–Gallwey score, body mass index, waist, blood pressure), hormone analyses (testosterone, sex hor...

Objective: PCOS may be associated with an increased risk of endometrial hyperplasia (EH) and endometrial cancer (EC), but substantial evidence remains to be established. We investigated the prevalence of EH and EC in a well-characterized group of women with PCOS and/or clinical/biochemical hyperandrogenism.Design: Retrospective, trans-sectional study.Setting: Out-patient clinic at the Departments of Endocrinology and Gynecology, Od...

Background: Clinical manifestations, metabolic risk factors and diabetes risk may differ in ethnical subgroups of women with PCOS.Material and methods: A total of 1010 premenopausal women were referred with the diagnoses hirsutism or PCOS during 1997–2008. The patients underwent clinical evaluation, hormone analyses and transvaginal ultrasound (US). Oral glucose tolerance tests (OGTT) (n=500) and ACTH tests (n=434) were performed in a ...

Background: Testosterone replacement therapy in severe hypogonadism is indicated, however, the treatment of late onset hypogonadism (LOH) is debated, especially what the diagnostic criteria should be. In LOH bio-available testosterone probably gives a more accurate index of gonadal status as a diagnostic criterion as it takes SHBG into consideration. SHBG is known to increase with ageing, however, SHBG is also negatively influenced by insulin and visceral adiposity.<p clas...

Objective: PCOS patients are often characterized by insulin resistance, abdominal obesity, and low-grade inflammation. Insulin sensitizing treatment reduces the inflammatory state, but the effect on serum levels of chemokines such as migration inhibitor factor (MIF), monocyte chemoattractant protein (MCP)-1, and macrophage inflammatory protein (MIP)-1α have not previously been evaluated in PCOS.Research design and methods: Plasma chemokine levels (M...
