OBJECTIVE: A long-hypothesized pathway through which low socioeconomic status (SES) harms health is through dysregulation of the physiologic stress response systems. No previous studies have tested this hypothesis by investigating cortisol reactivity and recovery to acute stress in relation to SES at different times in the life course in adults. Alteration of the cortisol response to an acute stressor could signal dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and has been associated with chronic illness...

The atrophy and hypofunction of the adrenal cortex following long-term pharmacologic glucocorticoid therapy are a major health problem necessitating chronic glucocorticoid replacement that often prolongs the ultimate return of endogenous adrenocortical function. Underlying this functional recovery is anatomic regeneration, the cellular and molecular mechanisms of which are poorly understood. Investigating the lineage contribution of cortical Shh+ progenitor cells and the SHH-responsive capsular Gli1+ cells to the regenerating adrenal cortex, we observed a spatially and temporally bimodal contribution of both cell types to adrenocortical regeneration following cessation of glucocorticoid treatment...

We examined the effects of six days of food restriction on salivary α-amylase (sAA), cortisol and dehydroepiandrostenedione (DHEA) awakening responses, psychological parameters and performance among eleven international weightlifters. Assessments were made at baseline (T1) and 6 days after a normal period of training while maintaining body weight (T2). Then, participants were assigned into two groups depending on whether they lost (Diet group) or maintained (Control group) their body weight. Anthropometric, psychological, physical and physiological assessments were also realized 6 days (T3) following the restricted dietary period for the Diet group...

Estradiol potentiates hypothalamic-pituitary-adrenal activity and delays the return of glucocorticoid secretion to baseline after a stressor exposure in female rats; we investigated whether estradiol effects involve actions on glucocorticoid receptor (GR) translocation and expression of receptor co-chaperones. In Experiment 1 intact females and ovariectomized (OVX) females were treated for four days with vehicle (VEH), 17β-estradiol benzoate (EB), or EB and progesterone (EB + P). Samples were taken from rats in the home cage (baseline) or after 30 min of restraint stress in a plastic restrainer (post-restraint) (n = 10/group)...

The aim of the present study was to detect prognostic factors in patients with skeletal-related events (SREs) and bone metastasis at the time of non-small-cell lung cancer (NSCLC) diagnosis. A total of 85 NSCLC patients were retrospectively enrolled, 47 (55.2%) of whom presented with SREs at the time of NSCLC diagnosis. Multivariate logistic regression analysis identified squamous cell carcinoma as a risk factor for SRE. Kaplan-Meier analysis demonstrated that there was no difference in the overall survival between the SRE and no SRE groups...

Glutathione transferases (GSTs) comprise a superfamily of enzymes prominently involved in detoxication by making toxic electrophiles more polar and therefore more easily excretable. However some GSTs have developed alternative functions. Thus, a member of the Alpha class GSTs in pig and human tissues is involved in steroid hormone biosynthesis, catalyzing the obligatory double-bond isomerization of Δ5-androstene-3,17-dione to Δ4-androstene-3,17-dione and of Δ5-pregnene-3,20-dione to Δ4-pregnene-3,20-dione on the biosynthetic pathways to testosterone and progesterone...

Progressive lipoprotein impairment occurs in liver cirrhosis and is associated with increased morbidity and mortality. The present review aims to summarize the current evidence regarding the prognostic value of lipoprotein abnormalities in liver cirrhosis and to address the need of a better prognostic stratification of patients, including lipoprotein profile assessment. Low levels of lipoproteins are usual in cirrhosis. Much evidence supports the prognostic role of hypolipidemia in cirrhotic patients. In particular, hypocholesterolemia represents an independent predictor of survival in cirrhosis...

BACKGROUND: Although the importance of steroidogenic factor-1 (SF1, NR5A1) for adrenal development is supported by numerous in vitro and in vivo studies, cases of SF1 deficiency associated with adrenal failure are exceptionally rare. The first human NR5A1 mutation was a heterozygous de novo p.G35E variant identified in a patient with disorder of sex development (DSD) 46,XY and primary adrenal insufficiency. Here we describe another association of the "classic" SF1 phenotype with a novel NR5A1 mutation affecting G35 residue...

RATIONAL: Primary malignant melanoma of the gallbladder is an extremely rare tumor, with fewer than 40 cases reported in the literature worldwide. The majority of patients presented as a solitary lesion in the gallbladder. To our knowledge, only one case of primary malignant melanoma of the gallbladder with multiple metastases has been reported, which involved the stomach, duodenum, pancreas, jejunum and a mesenteric lymph node. PATIENT CONCERNS: We report a case of primary malignant melanoma of the gallbladder with metastases to the duodenal bulb, right adrenal and a celiac lymph node...

Transitional cell carcinoma (TCC) urinary bladder is known to metastasize to regional lymph nodes (LNs), liver, lung, bone, adrenal glands, and intestine. However, an asymptomatic TCC bladder manifesting as metastatic axillary LN mass and extensive retroperitoneal lymphadenopathy is rarely heard of. A 46-year-old male, smoker, presented with 8 cm × 6 cm right axillary swelling of 1-month duration. Aspiration cytology revealed metastatic deposits of poorly differentiated carcinoma favoring TCC. Metastatic evaluation with (18)F-fluorodeoxyglucose positron emission tomography ((18)FDG-PET) scan showed mass lesion urinary bladder, conglomerate right axillary mass and extensive retroperitoneal LNs with significant metabolic activity, biopsy from which revealed deposits of TCC...

There is a growing body of research on yoga as a therapeutic intervention for psychological symptoms of post-traumatic stress disorder (PTSD) accompanied by speculations on underlying physiologic mechanisms. The purpose of this systematic review is to identify, qualitatively evaluate, and synthesize studies of yoga as an intervention for PTSD that measured physiologic outcomes in order to gain insights into potential mechanisms. The focus is on studies evaluating yoga as a therapeutic intervention for PTSD rather than for trauma exposure, PTSD prevention, or subclinical PTSD...

Depression, the most frequent psychiatric disorder following ischaemic stroke, negatively affects survivals' functional outcome, response to rehabilitation and quality of life. Approximately, one-third of them are affected by post-stroke depression (PSD), making it a serious social and public health problem and anti-depressant preventive and curative therapies worth investigating. However, a two-way association between depression and stroke has been also established: stroke increases the risk of PSD, but depression is an independent risk factor for stroke...

Hair cortisol concentration (HCC) is a promising measure of long-term hypothalamus-pituitary-adrenal (HPA) axis activity. Previous research has suggested an association between HCC and psychological variables, and initial studies of inter-individual variance in HCC have implicated genetic factors. However, whether HCC and psychological variables share genetic risk factors remains unclear. The aims of the present twin study were to: (i) assess the heritability of HCC; (ii) estimate the phenotypic and genetic correlation between HPA axis activity and the psychological variables perceived stress, depressive symptoms, and neuroticism; using formal genetic twin models and molecular genetic methods, i...

Central cholinergic systems regulate the hypothalamic-pituitary-adrenal (HPA) axis differentially in males and females (sexual diergism). We previously investigated the role of muscarinic receptors in this regulation by administering physostigmine (PHYSO), an acetylcholinesterase inhibitor, to male and female rats pretreated with scopolamine (SCOP), a nonselective muscarinic antagonist. SCOP pretreatment enhanced adrenocorticotropic hormone (ACTH) and corticosterone (CORT) responses in both sexes; males had greater ACTH responses while females had greater CORT responses...

Early-life stress is an established risk for the development of psychiatric disorders. Post-weaning isolation rearing of rats produces lasting developmental changes in behavior and brain function that may have translational pathophysiological relevance to alterations seen in schizophrenia, but the underlying mechanisms are unclear. Accumulating evidence supports the premise that gut microbiota influence brain development and function by affecting inflammatory mediators, the hypothalamic-pituitary-adrenal axis and neurotransmission, but there is little knowledge of whether the microbiota-gut-brain axis might contribute to the development of schizophrenia-related behaviors...

Endometrial cancer (EC) is the most common gynecologic malignancy prevailing after menopause. Defining steroid profiles may help predict the risk of recurrence after hysterectomy, which remains limited due to the lack of reliable markers. Adrenal precursors, androgens, parent estrogens and catechol estrogen metabolites were measured by mass spectrometry (MS) in preoperative serums and those collected one month after hysterectomy from 246 newly diagnosed postmenopausal EC cases. We also examined the associations between steroid hormones and EC status by including 110 healthy postmenopausal women...

BACKGROUND: Alterations of the hypothalamic-pituitary-adrenal (HPA) axis are a prominent finding in patients with major depressive disorder (MDD). Inconsistencies regarding a hyper- or hypoactive HPA axis may be explained by the moderating effect of childhood adverse experiences (ACE) which are associated with both HPA axis dysfunction and MDD in adulthood. We aimed to systematically disentangle the effects of ACE and MDD on HPA axis by comparing healthy women with and without childhood adversity and women with MDD with and without ACE...

The management of primary aldosteronism is widely varied within various published guidelines, with very little in the way of data supporting the choice of one variation over others. Current estimates of prevalence are probably accurate for aldosterone producing adenoma, but fall very short of that for bilateral adrenal hyperplasia. Discovery at the level of basic science has proven illuminating over the past 6 years in terms of unilateral disease and both somatic and germline mutations, with much less focus on the much more common bilateral disease; Attempts at harmonization have begun - for example, criteria for complete/partial/absent cure after adrenalectomy for unilateral disease; again focus on bilateral disease is muted...

The main treatment algorithm for adrenal insufficiency is hormonal replacement, however, inadequate hormone substitution often leads to severe side effects. Adrenal cell transplantation could be a more effective alternative but would require life-long immune suppressive therapy. PreImplantation Factor (PIF) is an endogenous peptide secreted by viable human embryos that leads to maternal tolerance without immunosuppression. PIF could be effective for xenogeneic cell transplantation such as of bovine adrenocortical cells (BAC), which are used for bioartificial adrenal gland development that may more effectively restore complex adrenal functions...
