Context: Previous studies suggest that total testosterone levels influences lipid metabolism. It has not been investigated whether these levels are prospectively associated with an unfavourable lipid profile including increased risk of incident dyslipidemia.Design and setting: We used data of 1468 men aged 20–79 years, repeatedly examined in the population-based Study of Health in Pomerania. Serum total testosterone levels, measured by chemiluminesc...

Increased corticosterone (cortisol in humans) in liver has important adverse effects on glucose metabolism and is therefore a target for diabetes treatments. The functional effects of corticosterone depend on circulating levels as well as tissue regeneration by 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1) and inactivation by steroid 5-α-reductase type I (5αR). This study investigates how obesity affects diurnal changes in circulating corticosterone, the ge...

Objective: Age- and gender-specific reference values for quality of life (QoL) measures are important to assess the impact of growth hormone deficiency (GHD). The objective of this study was to develop population-based data for the QoL-AGHDA instrument for Germany and to compare this data with corresponding Qol-AGHDA scores of the German KIMS cohort during growth hormone treatment, to investigate the association between the Qol-AGHDA score and the IGF-1 values in the German KI...

Background: Obesity is a major risk factor for the development of chronic diseases and a determinant of cardiovascular disease. Divergent associations between obesity and hormonal changes have been reported. The objective of the present study was to analyse the associations between different anthropometric measurements and serum hormone levels including insulin-like growth factor 1 (IGF-1), thyroid-stimulation hormone (TSH), prolactin, and testosterone.M...

The survival of the semiallogeneic fetus within the mother is thought to be due to mechanisms of immunological tolerance. Regulatory T cells (Treg) are believed to have a crucial role in maintaining pregnancy by creating a transient tolerant microenvironment within the maternal uterus as former studies confirmed. We have evidences that Treg expand in lymph nodes from normal pregnant mice already on day 2 of pregnancy. Abortion-prone mice present diminished numbers of Treg in i...

Background, objective: Adipose tissue is known to secrete a multitude of bioactive adipokines and it seems that the majority of these adipokines is implicated in the pathogenesis of obesity and associated metabolic diseases. Existing research studies mostly concentrated on one or two adipokines and therefore, comparisons of the involvement of different adipokines in these disorders are difficult. Furthermore, associations of circulating adipokine levels with different fat comp...

Introduction: Hypokalemia is one of the commonly encountered electrolyte derangements in clinical practice. Numerous conditions and certain medications can trigger hypokalemia such as Piperacillin/Tazobactam, Flucloxacillin, Cephalexin and Vancomycin.Case report: A 72-year-old lady was admitted following a fall sustaining a right neck of femur fracture. Prior to this admission, she was on chemotherapy for non-small cell ...

Background: The diagnosis of male hypogonadism can be difficult. Free testosterone is calculated if total testosterone is close to the lower limit of normal, however, this is inaccurate in conditions that alter sex-hormone-binding globulin. Alternatively, salivary testosterone is thought to reflect free testosterone, but is present at low concentrations, thus requiring sensitive mass spectrometry instrumentation, and there is limited data on the pre-analytical...

Introduction: National guidance from the Association of Children’s Diabetes Clinicians (ACDC) recommends starting children with newly diagnosed type 1 diabetes mellitus on a total daily insulin dose of 0.5–0.75 iU per kilo per day (kg/d). This equates to a basal insulin dose of between 0.25–0.375 iU/kg per day. Local practice suggested many patients required a significantly smaller starting dose of basal insulin.Ai...

Ovariectomy of immature female rats, results in significant decreased parameters in different organs. Previously we found that estradiol-17b (E2) restored these parameters in the different organs of ovariectomized female rats (Ovx) to values obtained in intact immature female rats. E2 also stimulated creatine kinase specific activity (CK) a hormonal-responsive marker in organs containing estrogen receptors. In the present study, we compared the effects of...
