Purpose: Previous studies have shown differences in baseline and stimulated cortisol levels between men and women. Whether this difference is secondary to sex hormones or to other factors, such as genetic or epigenetic changes, is unknown. We investigated the effect of gender-affirming hormone treatment (GAHT) on the hypothalamo-pituitary-adrenal axis of transgender subjects in an effort to throw light on this question.
Methods: Ten transgender males (TM) and eight transgender females (TF) underwent a low-dose (1 µg) adrenocorticotropic hormone (ACTH) stimulation test before and 6 months after GAHT initiation. Serum total, free and salivary cortisol (SC) levels were measured at baseline and at 20, 30 and 40 min.
Results: For the TM, all three levels were significantly lower at several time points after ACTH injection compared to pretreatment levels following 6 months of treatment (p < .05). Likewise, the overall SC response as calculated by the area under the curve was significantly lower (p = .0053). For the TF, the basal total cortisol (TC) level increased after 6 months of treatment (p < .01) while ACTH-stimulated SC levels decreased significantly. The basal ACTH levels were significantly lower following hormonal therapy (p < .001).
Conclusion: Stimulated salivary cortisol levels decreased significantly after 6 months of GAHT in both male and female transgender subjects, possibly reflecting a decreased state of anxiety associated with treatment initiation. Additionally, basal and stimulated serum TC levels increased after hormonal treatment in the TF, probably secondary to the effect of oestrogen on cortisol-binding globulin.

With freshwater resources becoming scarce worldwide, mariculture is a promising avenue to sustain aquaculture development, especially by incorporating brackish and saline groundwater (GW) use into fish farming. A 75-day rearing trial was conducted to evaluate fish growth, immune response, overall health, and water quality of Chelon ramada cultured in brackish GW and fed on a basal diet (BD) augmented with rosemary oil (RO) or RO + zymogen forte™ (ZF) as an anti-flatulent. Five treatments were administrated in triplicate: T1: fish-fed BD without additives (control group); T2: fish-fed BD + 0.

In a variety of settings, cortisol and testosterone are positively "coupled." That is, within-person fluctuations of these hormones occur in parallel, with increases and decreases in one hormone corresponding to increases and decreases in the other. A dataset comprised of salivary cortisol and testosterone levels from varsity women athletes from six different Emory University sports teams (volleyball 2002, 2005, and 2008; softball 2004; tennis 2009; soccer 2013) was used to explore the relationship between coupling and hormone reactivity to athletic competition.

Background: Managing postoperative pain and stress response was critical in laparoscopic myomectomy, a procedure for uterine fibroids. Ropivacaine transversus abdominis plane block (RTAPB) may offer enhanced analgesic efficacy and reduced stress responses compared to traditional analgesia.
Methods: This retrospective analysis examined 217 patients undergoing laparoscopic myomectomy at Hankou Hospital of Wuhan from June 2020 to September 2023.

Background: Pheochromocytoma is a rare neuroendocrine tumor, and bilateral pheochromocytomas is even less common. Due to the limited experience with such cases, this study aims to explore the optimal surgical strategy, assess the potential advantages of robotic surgery, and evaluate surgical outcomes for managing bilateral pheochromocytomas.
Case Description: This report presented a case of a 33-year-old woman with bilateral pheochromocytomas related to multiple endocrine neoplasia type 2a (MEN2A), who was successfully managed by synchronous transperitoneal robotic-assisted bilateral cortical-sparing adrenalectomy.

Purpose: Our study aimed to discern disparities in metabolic, hormonal profiles, and comorbidities among patients with pituitary Cushing (PC), adrenal Cushing (AC), and Mild autonomous cortisol secretion (MACS).
Methods: We conducted a retrospective analysis involving 76 patients diagnosed with PC ( = 26), AC ( = 21), and MACS ( = 29) at our clinic. We compared the groups' demographic data, clinical characteristics, biochemical profiles, hormonal analyses, and surgical interventions.
