Central disorders of hypersomnolence are rare conditions with a poorly understood pathophysiology, making the identification and management challenging for sleep clinicians. Clinical history is essential for ruling out secondary causes of hypersomnolence and distinguishing among diagnoses. Current diagnostic criteria rely heavily on the polysomnogram and multiple sleep latency test. The current focus of treatment of hypersomnolence is on drugs that promote alertness. Additionally, in the case of narcolepsy type 1, medication management addresses control of cataplexy, the hallmark symptom of this disorder. Elucidation of pathophysiology of these disorders in the future will be essential to better categorization and management.

Progress report on multiple endocrine neoplasia type 1.

Fam Cancer

Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel.

Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant disorder caused by a germline pathogenic variant in the MEN1 tumor suppressor gene. Patients with MEN1 have a high risk for primary hyperparathyroidism (PHPT) with a penetrance of nearly 100%, pituitary adenomas (PitAd) in 40% of patients, and neuroendocrine neoplasms (NEN) of the pancreas (40% of patients), duodenum, lung, and thymus. Increased MEN1-related mortality is mainly related to duodenal-pancreatic and thymic NEN.

Introduction: Obesity and its complications are associated with high morbidity/mortality and a significant healthcare cost burden in Spain. It is therefore essential to know the potential clinical and economic benefits of reducing obesity. The objective of this study is to predict the decrease in rates of onset of potential complications associated with obesity and the cost savings after a weight loss of 15% over 10 years in Spain.

Merestinib inhibits cuproptosis by targeting NRF2 to alleviate acute liver injury.

Free Radic Biol Med

January 2025

Wuxi School of Medicine, Jiangnan University, Wuxi, Jiangsu, 214122, China; Institute of Health and Medicine, Hefei Comprehensive National Science Center, Hefei 230601, China. Electronic address:

The emergence of cuproptosis, a novel form of regulated cell death, is induced by an excess of copper ions and has been associated with the progression of multiple diseases, including liver injury, cardiovascular disease, and neurodegenerative disorders. However, there are currently no inhibitors available for targeting specific cuproptosis-related pathways in therapy. Here, the compound merestinib (MTB) has been identified as a strong inhibitor of cuproptosis through screening of a kinase inhibitor library.
