Several studies have shown that ghrelin administration promotes wakefulness in rodents, while in human males it induces sleep but has no effect in women. Ghrelin also plays an important role in metabolism and appetite regulation, and as described in this review may participate in the energy balance during sleep. In this review, we summarize some of the effects induced by ghrelin administration on the sleep-wake cycle in relation to the effects of other hormones, such as growth hormone, leptin, and orexin. Finally we discuss the relationship between sleep deprivation, obesity and ghrelin secretion pattern.

Surrogate End Points for Overall Survival in Neoadjuvant Randomized Clinical Trials for Early Breast Cancer.
J Clin Oncol
January 2025
German Breast Group, Neu-Isenburg, Germany.
Purpose: To assess trial-level surrogacy value for overall survival (OS) of the pathologic complete response (pCR) and invasive disease-free survival (iDFS) in randomized clinical trials (RCTs) for early breast cancer (BC).
Methods: Individual patient data of neoadjuvant RCTs with available data on pCR, iDFS, and OS were included in the analysis. We used the coefficient of determination from weighted linear regression models to quantify the association between treatment effects on OS and on the surrogate end points.
Bone Health and Linear Growth in Children with Familial Hypoparathyroidism Treated with Human Parathyroid Hormone 1-34.
J Clin Endocrinol Metab
January 2025
Gastroenterology, Hepatology and Nutrition, Cincinnati Childrens Hospital Medical Center, Department of Pediatrics, University of Cincinnati College of Medicine, Cincinnati, OH.
Context: Our study explores the impact of human PTH 1-34 injections (PTH therapy) on growth, areal bone mineral density (BMD), and bone quality (measured by trabecular bone score, TBS) in hypoparathyroidism due to autoimmune polyendocrine syndrome type 1 (APS-1) or an activating variant of the calcium sensing receptor (CaR).
Objective: To assess associations of 1) age and PTH therapy duration with age-standardized Z-scores for height (HAZ), BMD (BMD-Z), and TBS (TBS-Z) in CaR or APS-1, and 2) APS-1 disease severity with BMD-Z and TBS-Z.
Methods: This secondary analysis pooled linear growth and lumbar spine (LS) DXA data from studies of hypoparathyroidism with mean baseline age of 13.

Growth hormone-releasing hormone signaling and manifestations within the cardiovascular system.

Growth hormone (GH)-releasing hormone (GHRH), a hypothalamic peptide initially characterized for its role in GH regulation, has gained increasing attention due to its GH-independent action on peripheral physiology, including that of the cardiovascular system. While its effects on the peripheral vasculature are still under investigation, GHRH and synthetic agonists have exhibited remarkable receptor-mediated cardioprotective properties in preclinical models. GHRH and its analogs enhance myocardial function by improving contractility, reducing oxidative stress, inflammation, and offsetting pathological remodeling.

The principle of the "growth-defense trade-off" governs how plants adjust their growth and defensive strategies in response to external factors, impacting interactions among plants, herbivorous insects, and their natural enemies. Mineral nutrients are crucial in modulating plant growth and development through their bottom-up effects. Emerging evidence has revealed complex regulatory networks that link mineral nutrients to plant defense responses, influencing the delicate balance between growth and defense against herbivores.
