Introduction: We questioned the justification of general recommendations for assessment of hypopituitarism in patients with traumatic brain injury (TBI), and aimed to describe the prevalence of hypopituitarism in a national TBI population of patients admitted to a Danish hospital in 2008, as compared to healthy controls.Patients and methods: We included 463 patients (18–65 years) hospitalized ≥24 h, with more than subtle TBI as indicated by lo...

Erythropoietin (Epo) treatment has been shown to induce mitochondrial biogenesis in cardiac muscle along with enhanced mitochondrial capacity in mice. We hypothesized that recombinant human Epo (rhEpo) treatment enhances skeletal muscle mitochondrial oxidative phosphorylation (OXPHOS) capacity in humans. In six healthy volunteers rhEpo was administered by s.c. injection over eight weeks with oral iron (100 mg) supplementation taken daily. Mitochondrial OXPHOS was quantified by...

Objective: To investigate the effect of pioglitazone on cortisol metabolism in PCOS.Design: Thirty insulin resistant PCOS patients were randomized to either 16 weeks of pioglitazone (30 mg/day) or placebo treatment. Before and after intervention, patients underwent 24 h 20 min.-integrated blood sampling for measurement of cortisol and 24 h excretion of cortisol, cortisone and steroid metabolites (cortisol, corticosteron, androgen, and 17-hydroxyprogester...

Objective: Transgender persons often experience low socioeconomic status. Gender affirming treatment aims to improve gender dysphoria. We assessed employment rates in transgender persons compared to controls and demographic, health and treatment-related factors associated with unemployment in transgender persons.Methods: National register-based cohort study in Danish transgender persons with diagnosis code of gender identity disorder during year 2000-202...

Background: Although polycystic ovary syndrome (PCOS) constitutes a common endocrinopathy, there are several issues which confuse clinicians during everyday practice.Objective: To define the current status of knowledge of the full spectrum of PCOS among European endocrinologists.Methods: A detailed questionnaire comprising 41 items covering various aspects of diagnosis and management of women with PCOS was shared via web among memb...

Background: Maternal free testosterone (FT) increases during 3rd trimester pregnancy and FT levels are higher in women with polycystic ovary syndrome (PCOS) compared to controls. Fetal exposure to maternal FT during 3rd trimester was associated with lower weight, length and shorter abdominal circumference at birth, in boys. Furthermore, lower birth weight has been related to higher abdominal fat mass in young children.Aim: To examine associations between...

Background: Perfluoroalkyl substances (PFAS) are endocrine disrupting chemicals, with elimination half-lives ranging from four to eight years. Experimental studies found PFAS able to interfere with thyroid hormone-binding proteins. During the first 20 weeks of gestation (GW), the fetus is reliant on placental transfer of maternal thyroid hormones, mainly free thyroxine (FT4). However, previous studies investigating associations between exposure to PFAS and thyroid hormone stat...

Background: Prolactin is associated with metabolic risk inside and outside of pregnancy. Maternal prolactin levels could be associated with offspring body composition.Aim: To investigate if maternal prolactin-levels were linked to offspring body composition at seven years of age.Design: Prospective observational cohort study (the Odense Child Cohort).Methods: Maternal fasting blood samples were assessed durin...

Background: Non-functioning pituitary adenomas (NFPAs) necessitate prolonged clinical, biochemical and radiological observation, constituting a significant burden in terms of medical resources and societal costs. Reliable biomarkers associated with aggressiveness and recurrence of NFPAs are lacking. As the growth of tumor remnants is highly variable, molecular markers that can predict growth potential and tumor behavior are necessary.Aim: To identify tar...

Context: Assessment of disease control in acromegaly depends on GH and IGF-I, but discordant values frequently occur. Further, the role of OGTT-suppressed GH (GHnadir) in somatostatin analogue (SA) treated patients is debated.Objective: To evaluate the effect of targeting either IGF-I or GH during SA treatment.Design: A randomized, investigator-initiated, multicentre trial.Patients and methods: 84 ...
