Introduction: Increasing neurobiological evidence has suggested the presence of a specific ecophenotype in people with eating disorders (EDs) linked to early maltreatment. Urinary-free cortisol could strengthen the data and show specific relationships between maltreated subtypes and the hormonal profiles of patients with EDs. This study aims to evaluate the presence of different urinary cortisol in drug-free patients in the acute phase of the disorder and its relationship with childhood maltreatment.
Methods: A sample of 78 female patients with ED is included in the study. Childhood maltreatment history and 24-h urinary free cortisol (24-h UFC) are evaluated at a specialised ED ward admission.
Results: Patients with a maltreatment history show more blunted 24-h UFC levels than peers without childhood maltreatment (p = 0.001). Regression analysis showed that child abuse is a predictor of the reduction of 24-h UFC (p < 0.001), with physical abuse (p = 0.011) and sexual abuse (p = 0.050) that could have a more specific impact than other maltreatment subtypes.
Discussion: Childhood maltreatment should be evaluated in ED patients due to its biological impact on the hormonal stress axis, which could impair the ability of patients to respond to standardized ED treatment.

Physicochemical properties of silicate tricalcium-based cement for use as pulp capping or repair material.
Braz Oral Res
January 2025
Universidade Federal do Ceará - UFC, School of Pharmacy, Dentistry and Nursing, Post-graduate Program in Dentistry, Fortaleza, CE, Brazil.
This study evaluated some physicochemical properties of an experimental tricalcium silicate-based cement (ETSC) indicated for use as pulp capping or endodontic repair material; Biodentine (BD) and White MTA-Angelus (MTA) cements served as comparators. Setting time, radiopacity, sorption, and solubility were determined according to ISO 6876/2012 and compressive strength according to ISO 9917-1/2019. pH and calcium ion release capacity were also assessed.

Background: Several studies have evaluated different cell cycle synchronization methods to improve reprogramming efficiency aimed at wild species conservation. The six-banded armadillo is one of the wild mammals with significant ecological and biomedical interests but has not yet been evaluated for reprogramming purposes.
Objective: We investigated the effects in a time-dependent manner of serum starvation (SS; 0.

Introduction: Consuming hypercaloric diets during pregnancy induces metabolic, immune, and maternal intestinal dysbiosis disorders. These conditions are transferred to the offspring through the placenta and breastfeeding, increasing susceptibility to metabolic diseases. We investigated the effect of GG supplementation on offspring maternally programmed with a hypercaloric diet.

Article Synopsis
- The study investigates how common hypothalamic-pituitary-adrenal (HPA) axis suppression is among kidney transplant recipients (KTRs) on low doses of glucocorticoids, highlighting that 27.5% had low cortisol levels.* -
- It found that KTRs with low cortisol levels tended to be older and longer post-transplant, with cortisol levels positively correlating with other hormones like ACTH and DHEAS.* -
- Despite increased HPA axis suppression in these patients, the study concluded that it was not linked to metabolic disorders like hypertension or diabetes, suggesting ACTH could be a useful biomarker for monitoring HPA activity.*
Long-term outcome of unilateral adrenalectomy for primary bilateral macronodular adrenal hyperplasia.

Article Synopsis
- The study investigates the long-term effectiveness of unilateral adrenalectomy (U-Adx) as a treatment for primary bilateral macronodular adrenal hyperplasia (PBMAH), a type of Cushing's syndrome, which traditionally required bilateral adrenalectomy but posed significant risks.
- Researchers evaluated 61 patients treated with U-Adx between 2004 and 2022, analyzing their postoperative biochemical outcomes and improving comorbidities such as hypertension and glucose metabolism.
- Results showed that about 50% of patients achieved initial remission within six months; however, a significant percentage experienced persistent hypercortisolism or recurrence at the last follow-up, highlighting the need for further understanding of prognostic predictors for
