Yawning is a significant behavioural response and, together with cortisol, is potentially a new diagnostic marker of neurological diseases. Evidence of an association between yawning and cortisol was found which supports the Thompson Cortisol Hypothesis and thermoregulation hypotheses, indication that brain cooling occurs when yawning. 117 volunteers aged 18-69 years were randomly allocated to experimentally controlled conditions to provoke yawning. Thirty-three had been diagnosed with multiple sclerosis. Saliva cortisol samples were collected before and after yawning or after stimuli presentation in the absence of yawning...

Aldosterone- and cortisol-coproducing adrenal adenoma (A/CPA) cases have been observed in patients with primary aldosteronism (PA). This study investigated the incidence, clinical characteristics, and molecular biological features of patients with A/CPAs. We retrospectively identified 22 A/CPA patients from 555 PA patients who visited the Chinese People's Liberation Army General Hospital between 2004 and 2015. Analysis of clinical parameters revealed that patients with A/CPAs had larger tumors than those with pure APAs ( P < 0...

A plethora of cross-sectional studies suggest that psychological stress resulting from experiencing stressful life events (SLE) can result in an altered immune response. Potential maladaptive immune changes may outlast the event and affect the organism long after stress cessation. As a consequence, an increased vulnerability for immune-mediated pathologies (e.g. arthritis, diabetes) may develop over the life span. The objective of the present study was to monitor the longitudinal kinetics of peripheral white blood cells (WBCs; neutrophils, lymphocytes, and monocytes) in response to SLE...

11β-Hydroxysteroid dehydrogenase type 1 (11β-HSD1) is an enzyme that catalyzes the conversion of inactive cortisone into physiologically active cortisol. Inhibiting the activity of this enzyme plays a key role in the treatment of Cushing's syndrome, metabolic syndrome and type 2 diabetes. Therefore, new compounds that are selective inhibitors of this enzyme are constantly being looked for. In this work we present the synthesis of 2-(allylamino)thiazol-4(5H)-one derivatives by the reaction of N-allylthiourea with appropriate α-bromoesters...

Background: Alström syndrome (AS), a monogenic form of obesity, is caused by recessive mutations in the centrosome- and basal body-associated gene, ALMS1. AS is characterized by retinal dystrophy, sensory hearing loss, cardiomyopathy, childhood obesity, and metabolic derangements. Objective: We sought to characterize the endocrine and metabolic features of AS while accounting for obesity as a confounder by comparing patients with AS to BMI-matched controls. Methods: We evaluated 38 patients with AS (age 2-38y) who were matched with 76 controls (age 2-48y) by age, sex, race, and BMI...

BACKGROUND: Children exposed to gestational diabetes mellitus (GDM) in utero are at increased risk of neurodevelopmental difficulties, including autism and impaired motor control. However, the underlying neurophysiology is unknown. METHODS: Using transcranial magnetic stimulation, we assessed cortical excitability, long-term depression (LTD)-like neuroplasticity in 45 GDM-exposed and 12 control children aged 11-13 years. Data were analysed against salivary cortisol and maternal diabetes severity and treatment (insulin [N = 22] or metformin [N = 23]) during pregnancy...

Glucocorticoids (GC), such as cortisol or dexamethasone, control various physiological functions, notably those involved in development, metabolism, inflammatory processes and stress, and exert most of their effects upon binding to the glucocorticoid receptor (GR, encoded by NR3C1 gene). GC signaling follows several consecutive steps leading to target gene transactivation, including ligand binding, nuclear translocation of ligand-activated GR complexes, DNA binding, coactivator interaction and recruitment of functional transcriptional machinery...

The theory of resilience and relational load was tested with 60 couples and their adolescent children (ages 11-18) with type I diabetes (T1D). The couples participated in a stress-inducing conversation task in their home, followed by a random assignment to a two-week intervention designed to increase their relationship maintenance. Before the intervention, stronger communal orientation predicted greater maintenance for husbands and wives, but maintenance only reduced T1D stress for wives. The wives' and adolescents' T1D stress were also correlated, but the husbands' T1D stress was not significantly associated with either of them...

"Subclinical hypercortisolism" (SH) refers to a condition associated with a mild chronic increase in cortisol secretion. By definition, patients with SH do not exhibit specific symptoms of overt Cushing's syndrome (such as purple striae, easy bruising, proximal muscle weakness), SH has been preferred to "subclinical Cushing's syndrome", a semantic ambiguity since Cushing's syndrome is, by definition, a set of symptoms; and to the term "preclinical Cushing syndrome" because the progression toward overt clinical hypercortisolism is very rare...

AIMS: Maintained glucagon response to hypoglycaemia is important as a safeguard against hypoglycaemia during glucose-lowering therapy in type 2 diabetes. During recent years, DPP-4 (dipeptidyl peptidase-4) inhibition has become more commonly used in elderly patients. However, whether DPP-4 inhibition affects the glucagon response to hypoglycaemia in the elderly is not known and was the aim of this study. METHODS: In a single-center, double-blind, randomized, placebo-controlled crossover study, 28 subjects with metformin-treated type 2 diabetes (17 males, 11 females; mean 74 years (range 65-86 years), mean HbA1c 51...

Co-existence of craniopharyngioma and acromegaly has been very rarely reported. A 65-year-old man presented with visual deterioration, fatigue and frontal headaches. Magnetic resonance imaging revealed a suprasellar heterogeneous, mainly cystic, 1.9 × 2 × 1.9 cm mass compressing the optic chiasm and expanding to the third ventricle; the findings were consistent with a craniopharyngioma. Pituitary hormone profile showed hypogonadotropic hypogonadism, mildly elevated prolactin, increased insulin-like growth factor 1 (IGF-1) and normal thyroid function and cortisol reserve...

Patients with adrenal incidentaloma (AI) and subclinical hypercortisolism (SH) show a high prevalence of cardiovascular risk factors and an increased prevalence and incidence of cardiovascular events. Furthermore, some recent data suggest that in these patients, the cardiovascular mortality is also increased. Unfortunately, to date, the diagnosis of SH is still a matter of debate, and, therefore, it is still not possible to address the treatment of choice (i.e. surgical or conservative approach) in many AI patients...

Insulin resistance (IR) is a common denominator of metabolic and hemodynamic disorders simultaneously present in one person and responsible for elevated risk of developing type 2 diabetes (T2DM) and cardiovascular incidents. According to the latest research, IR is present in 25-45% of the general population. Therefore, the mechanism of its development is in the center of scientific and professional interest. Established or acquired factors, or combinations thereof, which disturb any step of the physiological insulin action mechanism: its binding to the cellular receptor, through the complex cascade of intracellular signaling pathways might cause IR...

Background: An Okinawa-based Nordic diet with moderately low carbohydrate content and high fat and protein content has been shown to improve anthropometry and metabolism in type 2 diabetes. Objective: The objectives of this study were to measure plasma or serum levels of hormones regulating energy metabolism and metabolic control, that is, cholecystokinin (CCK), Cortisol, C-peptide, ghrelin, glucagon, glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), insulin, leptin, plasminogen activator inhibitor-1 (PAI-1), polypeptide YY (PYY), resistin, and visfatin after this diet intervention, and to determine partial correlations between hormonal levels and anthropometric and metabolic responses...

OBJECTIVE: Pre-diabetes and type 2 diabetes (i.e., hyperglycemia) are characterized by insulin resistance (IR). These problems with energy metabolism may exacerbate emotional reactivity to negatively valenced stimuli and related phenomena like predisposition toward negative affect, as well as cognitive deficits. Higher emotional reactivity is seen with hyperglycemia and IR. Yet, it is largely unknown how metabolic dysfunction correlates with related neural, hormonal, and cognitive outcomes...

Context: Hypoglycemia, one of the major factors limiting optimal glycemic control in insulin-treated diabetic patients, elicits a brain response to restore normoglycemia by activating counterregulation. Animal data indicate that local release of norepinephrine in the hypothalamus is important for triggering hypoglycemia-induced counterregulatory (CR) hormonal responses. Objective: To examine the potential role of brain noradrenergic activation in humans during hypoglycemia...

PURPOSE: The increasing prevalence of obesity and/or metabolic syndrome (O/MS) and diabetes mellitus (DM) remains a global health concern. Clinically relevant and practical translational models mimicking human characteristics of these conditions are lacking. This study aimed to demonstrate proof of concept of the induction of stable O/MS and type 2 DM in a Göttingen minipig model and validate both of these disease-adjusted Göttingen minipig models as impaired healing models for the testing of dental implants...

PURPOSE: Data about the specificity of late-night salivary cortisol (LNSC) in obese subjects are still conflicting. Therefore, with this study, we aimed to evaluate the specificity of LNSC measurement in an obese cohort with or without type 2 diabetes mellitus (T2DM) using an automated electrochemiluminescence immunoassay (ECLIA). METHODS: A total number of 157 patients involving 40 healthy subjects (HS) with BMI < 25 kg/m2 , 83 obese subjects (OS) with BMI ≥ 35 kg/m2 , and 34 histopathologically proven Cushing's disease (CD) were included...

Christina Schumann, Michael Faust
BACKGROUND:  Diabetic ketoacidosis and the hyperosmolar hyperglycemic state are the most serious diabetic emergencies. Before the discovery of insulin in 1921 by Banting and Best the diagnosis of type 1 diabetes was fatal ending in diabetic ketoacidosis equivalent to a torturous death. Today, mortality from diabetic ketoacidosis is low at approximately 2 %. But each death from these two acute metabolic complications of diabetes is potentially avoidable by improved patient and healthcare professional education...

The pituitary stalk (PS) is a relatively thin bundle connecting the hypophyseal stalk to the pituitary gland; it consists of both axons of the hypothalamic nuclei (terminating in the neurohypophysis) and the system of portal vessels. Compression of the PS by a space-occupying lesion or its transection (forced or intended) during surgery may lead to the development of endocrine disorders: hypopituitarism, diabetes insipidus, and hyperprolactinemia. The modern literature lacks studies evaluating the severity of endocrine disorders depending on the PS condition before and after surgery...
