Article Abstract
A dysregulated hypothalamic-pituitary-adrenal (HPA) axis in patients with type 2 diabetes (T2D), a condition preceded by prediabetes, has been shown to exacerbate the hyperglycaemic state, increasing the risk of depression. However, HPA axis activity in a prediabetic state-as well as whether the prediabetic state affects HPA axis regulation-is not fully understood. This study investigated the activity of the HPA axis in selected biomarkers and hormones related to HPA axis regulation in individuals with prediabetes. The study used samples obtained from adults aged between 25 and 45 of all ethnicities from the King Edward VIII Hospital. The samples were divided into three groups-non-prediabetic (NPD) ( = 40), prediabetic (PD) ( = 40), and T2D ( = 40)-based on the participant's glycated haemoglobin percentage. The cortisol (CORT), adrenocorticotropic hormone (ACTH), insulin, epinephrine (EPI), and norepinephrine (NE) concentrations of the samples were measured. The plasma CORT and ACTH concentrations in the PD group were higher compared to the NPD group. Plasma insulin concentration was increased only in the T2D group. There was also an increase in the plasma epinephrine concentration in the T2D group as compared to the NPD and PD groups. These observations collectively suggest that prediabetes is associated with heightened HPA axis activity and may alter HPA axis regulation, which may cause an altered stress response.

Topical Glucocorticoid-Induced Cushing's Syndrome in a Patient with Erythrodermic Psoriasis: A Case Report.

Background: Topical glucocorticoids are widely used in psoriasis treatment but may lead to systemic adverse effects, particularly with prolonged use. While pediatric cases are well-documented, adult-onset iatrogenic Cushing's syndrome from topical corticosteroids remains under-recognized.
Case Presentation: A 31-year-old woman with a 10-year history of psoriasis vulgaris self-administered high-potency clobetasol propionate ointment (monthly cumulative dose escalated from 30 g to 100 g over 22 months) under no physician supervision.

The body of knowledge on trauma is rapidly expanding. Since 2022, the WHO has been calling for the history of adversity to be systematically taken into account when assessing the state of health of all individuals. But at this stage, our understanding of the precise mechanisms of complex trauma remains incomplete.

When under stress, individuals often make suboptimal decisions due to altered decision-making strategies. These alterations may be particularly costly in high-risk scenarios, yet the precise relationship between acute stress and risk-taking behavior remains unclear. In the present pilot study, using a quasi-experimental design, we examined whether an experimentally induced psychosocial stressor would elevate RTB under competitive conditions.

Insulin tolerance tests (ITTs), glucagon tests, and low or standard-dose adrenocorticotropic hormone tests are used to evaluate the hypothalamic-pituitary-adrenal (HPA) axis. While ITT is considered the gold standard test for stimulating both the cortisol and growth hormone axis, its use in young children carries a risk of hypoglycemia, making it potentially unsafe. Recent studies indicate that L-dopa stimulates the release of adrenocorticotropic hormone and cortisol.

Objectives: To clarify the role of hippocampal glutamate system in regulating HPA axis in mediating the effect of electroacupuncture (EA) at the heart meridian for improving myocardial injury in rats with acute myocardial ischemia (AMI).
Methods: Male SD rats were randomized into sham-operated group, AMI group, EA group, and L-glutamic acid+EA group (=9). Rat models of AMI were established by left descending coronary artery ligation, and EA was applied at the "Shenmen-Tongli" segment; the rats in L-glutamic acid+EA group were subjected to microinjection of L-glutamic acid into the bilateral hippocampus prior to AMI modeling and EA treatment.
