Background: Birth weight has been associated with low bone mass in later life. Previous studies, however, have relied on self-reported data on birth weight, included select populations, or been of a limited size. Moreover, it is unclear if the association between birth weight and bone mass is be mediated by body weight, lean body mass, or fat mass.Aim: We hypothesize that birth weight is associated with peak bone mass in men independent of current lean b...

Beta-cell function of HIV-infected patients on highly active antiretroviral therapy (HAART), who display lipodystrophy, may be impaired. An early defect in beta-cell function may be characterized by an increased secretion of 32–33 split proinsulin (SP) and intact proinsulin (IP).To address this issue the secretion pattern of SP and IP of 16 HIV-infected men with lipodystrophy (LIPO) and 15 HIV-infected men without lipodystrophy (NONLIPO) were studie...

Objective: High dose growth hormone (rhGH) regimens (2 to 4 mg/day) have been shown to increase circulating insulin-like growth factor (IGF)-I to supra-physiological levels in human immunodeficiency virus (HIV)-infected patients on combined antiretroviral therapy (CART). This setting may improve immunologic output. However, a high plasma IGF-I concentration has detrimental effects on glucose metabolism, which hampers the use of high dose rhGH regimens.Me...

Both humic substances (HS) and iodine may influence the thyroid gland. Tap water is a major source of iodine intake in some areas, where iodine has been shown to be bound in HS.We investigated tap water and old subjects from two areas with and without iodine bound in HS in tap water, to assess their importance for urinary iodine excretion and for the thyroid. Analysis of tap water, measurement of iodine in urine and thyrotropin (TSH), thyroid peroxidase ...

Background: Polycystic ovary syndrome (PCOS) is associated with obesity and low grade inflammation, factors linked to cardiovascular disease (CVD).Methods: National Register-based study including women with PCOS and no previous diagnosis of CVD or hypertension. PCOS OUH (n=1165) included premenopausal women with PCOS and clinical and biochemical examination. PCOS Denmark (n=18 112) included women with PCOS in the Danish National Patient...

The luteinising hormone/chorionic gonadotropin receptor (LHCGR) plays an essential role in ovarian follicular function, mediating the action of LH on theca cell steroidogenesis and, in the preovulatory follicle, on granulosa cell (GC) steroid production and the ovulatory cascade. Following ovulation, LH (and CG) are responsible for maintenance and function of the corpus luteum. Arrested antral follicle development in PCOS is characterised by premature responsiveness of GCs to ...

Introduction: Iodine is essential for thyroid funciton and severe deficiency adversely affects the developing brain. A raised and sufficient intake is particularly important during the pregnancy. Iodine sources include sea foods and sea salt, and it is available as a dietary supplement. The former was previously important to the Faroses diet but the intake of traditional Faroses foods is decreasing with at likely parallel influence on the iodine intake. Currently, there is no ...

Objectives: Thyroid disease in women of reproductive age is predominantly of autoimmune origin, and thyroid peroxidase antibodies (TPO-Ab) as well as thyroglobulin antibodies (Tg-Ab) are key markers of autoimmune hypothyroidism. Adding to this, much focus in pregnancy is on euthyroid women who are positive for thyroid autoantibodies. The observational findings are diverse, and evidence to substantiate the applied cut-offs for definition of thyroid autoantibody-positivity in ea...

Background: Gender affirming hormonal treatment (GAHT) is for many a cornerstone of transgender care. National data regarding use of hormonal treatment by transgender persons are limited.Aim: To assess use of GAHT in transgender persons.Design: National register-based cohort study in Danish transgender persons followed from 2000 until 2018. The main outcome measure was redemption of GAHT. Persons with an ICD-10 diagnosis code of &#...

Background: Language development during early childhood is considered an important marker of fetal neurodevelopment. Prenatal cortisol exposure plays a critical role in maturation of the fetal brain; however, the effect on offspring language development needs further investigation. This study aimed to evaluate the association between maternal 3rd trimester cortisol and early longitudinal offspring language development and to test whether there was sex differences in...
