REVIEW
Jacob C Jentzer, Saraschandra Vallabhajosyula, Ashish K Khanna, Lakhmir S Chawla, Laurence W Busse, Kianoush B Kashani
Refractory shock is a lethal manifestation of cardiovascular failure defined by an inadequate hemodynamic response to high doses of vasopressor medications. Approximately 7% of critically ill patients will develop refractory shock, with short-term mortality exceeding 50%. Refractory vasodilatory shock develops from uncontrolled vasodilation and vascular hyporesponsiveness to endogenous vasoconstrictors, causing failure of physiologic vasoregulatory mechanisms. Standard approaches to initial management of shock include fluid resuscitation and initiation of norepinephrine...

Fingertip units have been proposed as a tool to standardize topical therapy with semisolid formulations. However, no studies to date have characterized the variability in dosing by patients using this concept and whether this variability ultimately affects the topical absorption of drugs. This work aimed to answer these two questions. A first study determined the dose measured, the area of spread and the area-normalized dose for a 1% hydrocortisone cream and ointment applied by members of the public using this dosing approach before and after brief counselling...

Intertemporal choices - decisions involving trade-offs of outcomes at different points in time - are often made under stress. Stress activates the hypothalamic-pituitary-adrenal (HPA) axis, resulting in the release of corticosteroids. Recent studies provide evidence that corticosteroids can induce rapid non-genomic effects focused on immediate resolution of the stressful situation, followed by slower genomic effects focused on long-term recovery after stress. It remains unknown, however, how corticosteroids affect intertemporal choice...

Ginseng has been reported to have diverse pharmacological effects. One of the therapeutic claims for ginseng is to enhance sexual function. Ginsenosides are considered as the major active constituents. A steaming process can alter the ginsenoside profile of ginseng products. The structure-function relationship of ginsenosides in the treatment of erectile dysfunction (ED) has not been investigated yet. In this work, 15 different processed ginsengs are produced by steaming, and 13 major ginsensosides are quantified by liquid chromatography with UV detection, including Rg1, Re, Rf, Rb1, Rc, Rb2, Rf, Rk3, Rh4, 20S-Rg3, 20R-Rg3, Rk1, and Rg5...

Cushing's syndrome requires glucocorticoid replacement following adrenalectomy. Based on a simplified glucocorticoid therapy scheme and the peri-operative observation, we investigated its efficacy and safety up to 6 months post-adrenalectomy in this cohort study. We found the adrenocorticotropic hormone (ACTH) levels were normal post-adrenalectomy, and sufficient to stimulate the recovery of the dystrophic adrenal cortex, thus exogenous supplemental ACTH might not be necessary. Patients were grouped by oral reception of either hydrocortisone or prednisone since day 2 post-adrenalectomy...

Adrenal androgen excess is the hallmark of classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. Recently, 11-oxygenated C19 steroids, a class of highly active adrenal-derived androgens, have been described in patients with CAH. The aim of our study was to elucidate the significance of 11-oxygenated androgens in children with CAH. We retrospectively analysed 190 daily urinary excretion rates of glucocorticoid-, 17α-hydroxyprogesterone (17OHP)-, and androgen metabolites determined by gas chromatography-mass spectrometry of 99 children aged 3...

Oxytocin is associated mainly with modulating reproductive function. However, studies suggest that oxytocin also plays a role in endocrine pancreatic function. In the present study, islet expression of oxytocin and its related receptor was confirmed in mouse islets as well as cultured rodent and human beta-cells. Oxytocin significantly stimulated glucose-induced insulin secretion from isolated mouse islets. Similar insulinotropic actions were also observed in rodent BRIN BD11 and human 1.1B4 beta-cells. Positive effects of oxytocin on insulin secretion were almost fully annulled by the oxytocin receptor antagonist, atosiban...

REVIEW
Kamani Liyanarachchi, Richard Ross, Miguel Debono
The daily rhythm of the hypothalamo-pituitary-adrenal (HPA) axis is regulated by the central clock in the suprachiasmatic nucleus. Cortisol, a glucocorticoid, acts as a secondary messenger between the central clock and the peripheral tissues. Changes in clock time, as seen in shift workers, alters the HPA axis and results in metabolic disturbances associated with ill health. Depression, anorexia nervosa and obstructive sleep apnoea, are associated with cortisol rhythm phase shifts and increased cortisol exposure...

Christine L Hammer, Tamara A Franz-Odendaal
Previous work, almost four decades ago, showed that hydrocortisone (HC) treatment reduces the number of skeletogenic condensations that give rise to the scleral ossicles in the chicken eye. The scleral ossicles are a ring of overlapping intramembranous bones, the sclerotic ring, and are present in most reptiles, including birds. The scleral condensations that give rise to the scleral ossicles are induced by a series of overlying thickenings (or papillae) of the conjunctival epithelium. Here, we further explore the effects of altering the dosage and timing of HC treatment on the morphology and number of skeletogenic condensations and conjunctival papillae...
