Emergency contraception (EC) is a way to significantly reduce the chance of becoming pregnant after an episode of unprotected intercourse. Considerable data support the safety of all available and emerging options for EC. Areas covered: This review presents a comprehensive summary of the literature regarding the safety of EC as well as directions for further study. PubMed was searched for all relevant studies published prior to June 2017. Expert Opinion: All available methods of EC (i.e., ulipristal acetate pills, levonorgestrel pills, and the copper-IUD), carry only mild side effects and serious adverse events are essentially unknown...

BACKGROUND: Psychotic depression has no Food and Drug Administration-approved treatment. Patients demonstrate significant dysregulation of the hypothalamic-pituitary-adrenal axis providing a biologically targeted treatment opportunity. The purpose of this study was to explore the clinical and biological effects of short-duration (7-day) glucocorticoid receptor antagonism with mifepristone and the role of mifepristone plasma levels in patients with psychotic depression. METHODS: This double-blind, randomized study took place at 34 US clinical research centers and included patients with a diagnosis of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, major depressive disorder, severe, with psychotic features...

Alcohol dependence is linked to dysregulation of the hypothalamic-pituitary-adrenal axis. Here, we investigated effects of repeated ethanol intoxication-withdrawal cycles (using chronic intermittent ethanol vapor inhalation; CIE) and abstinence from CIE on peak and nadir plasma corticosterone (CORT) levels. Irritability- and anxiety-like behaviors as well as glucocorticoid receptors (GR) in the medial prefrontal cortex (mPFC) were assessed at various intervals (2h-28d) after cessation of CIE. Results show that peak CORT increased during CIE, transiently decreased during early abstinence (1-11d), and returned to pre-abstinence levels during protracted abstinence (17-27d)...

Acute alcohol exposure suppresses cell inflammatory response. The underlying mechanism has not been fully defined. Here we report that alcohol was able to activate glucocorticoid receptor (GR) signaling in the absence of glucocorticoids (GCs) and upregulated glucocorticoid-induced leucine zipper (gilz), a prominent GC-responsive gene. Such a non-canonical activation of GR was not blocked by mifepristone, a potent GC competitor. The proximal promoter of gilz, encompassing five GC-responsive elements (GREs), was incorporated and tested in a luciferase reporter system...

A tight interaction between endocrine and immune systems takes place mainly due to the key role of head kidney in both hormone and cytokine secretion, particularly under stress situations in which the physiological response promotes the synthesis and release of stress hormones which may lead into immunomodulation as side effect. Although such interaction has been previously investigated, this study evaluated for the first time the effect of stress-associated hormones together with their receptor antagonists on the expression of cytokine genes in head kidney primary cell culture (HKPCC) of the freshwater rainbow trout (Oncorhynchus mykiss) and the seawater gilthead sea bream (Sparus aurata)...

This article provides information on recent changes in the US Food and Drug Administration (FDA) labeling and safety regulations for mifepristone (Mifeprex). The revised label now permits midwives, advanced practice nurses, and physician assistants to order and prescribe mifepristone, eliminating the requirement for physician supervision. The updated label also extends eligibility for use from 49 to 70 days' gestation and decreases the number of required visits from 3 to 2. The recommended dose of mifepristone has been reduced, and the dosage, timing, and route of administration for misoprostol have also been changed to reflect current research...

Despite decades of advocacy among Thai governmental and nongovernmental actors to remove abortion from the country's 1957 Criminal Code, this medically necessary service remains significantly legally restricted. In 2005, in the most recent regulatory reform to date, the Thai Medical Council established regulatory measures to allow a degree of physician interpretation within the confines of the existing law. Drawing on findings from a review of institutional policies and legislative materials, key informant interviews, and informal discussions with health service providers, government representatives, and nonprofit stakeholders, this article explores how legal reforms and health policies have shaped the abortion landscape in Thailand and influenced geographic disparities in availability and accessibility...

Neuroinflammation mediated by NLRP-1 inflammasome plays an important role in the pathogenesis of neurodegeneration diseases such as Alzheimer's disease (AD). Chronic glucocorticoids (GCs) exposure has deleterious effect on the structure and function of neurons and was found to be correlated with development and progression of AD. We hypothesize that chronic glucocorticoids may down-regulate the expression of glucocorticoids receptor (GR) and activate NLRP-1 inflammasome in hippocampal neurons, which may promote neuroinflammation and induce neuronal injury...

Preterm birth (PTB) is the leading cause of neonatal mortality and morbidity, with few prevention and treatment options. Uterine contraction is a central feature of PTB, so gaining new insights into the mechanisms of this contraction and consequently identifying novel targets for tocolytics are essential for more successful management of PTB. Here we report that myometrial cells from human and mouse express bitter taste receptors (TAS2Rs) and their canonical signaling components (i.e., G-protein gustducin and phospholipase C β2)...

The basolateral amygdala (BLA) is a critical site for the reconsolidation of labile contextual cocaine memories following retrieval-induced reactivation/destabilization. Here, we examined whether glucocorticoid receptors (GR), which are abundant in the BLA, mediate this phenomenon. Rats were trained to lever press for cocaine reinforcement in a distinct environmental context, followed by extinction training in a different context. Rats were then briefly exposed to the cocaine-paired context (to elicit memory reactivation and reconsolidation) or their home cages (no reactivation control)...

Glucocorticoids have been widely used and exert pleiotropic effects on alveolar structure and function, but do not improve the long-term clinical outcomes for patients with bronchopulmonary dysplasia, emphysema, or interstitial lung diseases. Treatments which foster alveolar regeneration could substantially improve the long-term outcomes for such patients. One approach to alveolar regeneration is to stimulate and guide intrinsic alveolar progenitors along developmental pathways used during secondary septation...
