Once-weekly semaglutide doubles the five-year risk of nonarteritic anterior ischemic optic neuropathy in a Danish cohort of 424,152 persons with type 2 diabetes.

Background: Nonarteritic anterior ischemic optic neuropathy (NAION) is an untreatable condition often causing severe and irreversible visual loss in the affected eye. As it has recently been implied that the use of semaglutide associates with NAION, the aim of the present study was to evaluate this risk prospectively in all persons with type 2 diabetes (T2D) in Denmark.

Methods: In a five-year longitudinal cohort study, we identified all persons with T2D in Denmark (n = 424,152) between 2018 and 2024.

Comparative Analysis of Plasma Protein Dynamics in Women with ST-Elevation Myocardial Infarction and Takotsubo Syndrome.

Background: ST-elevation myocardial infarction (STEMI) and Takotsubo syndrome (TS) are two distinct cardiac conditions that both result in sudden loss of cardiac dysfunction and that are difficult to distinguish clinically. This study compared plasma protein changes in 24 women with STEMI and 12 women with TS in the acute phase (days 0-3 post symptom onset) and the stabilization phase (days 7, 14, and 30) to examine the molecular differences between these conditions.

Methods: Plasma proteins from STEMI and TS patients were extracted during the acute and stabilization phases and analyzed via quantitative proteomics.

Metabolic Dysfunction in New-Onset Idiopathic Intracranial Hypertension: Identification of Novel Biomarkers.

Objective: Idiopathic intracranial hypertension (IIH) is a neurometabolic disease with an increasing incidence. The pathophysiology is unknown, but improvement of diagnosis and management requires discovery of novel biomarkers. Our objective was to identify such candidate biomarkers in IIH, and secondarily, test for associations between identified metabolites and disease severity.

Magnetic Resonance Imaging Signs of Idiopathic Intracranial Hypertension.

Importance: The magnetic resonance imaging (MRI) criteria currently used to diagnose idiopathic intracranial hypertension (IIH) are based on expert opinion and have limited accuracy. Additional neuroimaging signs have been proposed and used with contradictory results; thus, prospective evidence is needed to improve diagnostic accuracy.

Objective: To provide evidence-based, accurate MRI signs for IIH diagnosis.

The Alk receptor tyrosine kinase regulates Sparkly, a novel activity regulating neuropeptide precursor in the central nervous system.

Numerous roles for the Alk receptor tyrosine kinase have been described in , including functions in the central nervous system (CNS), however the molecular details are poorly understood. To gain mechanistic insight, we employed Targeted DamID (TaDa) transcriptional profiling to identify targets of Alk signaling in the larval CNS. TaDa was employed in larval CNS tissues, while genetically manipulating Alk signaling output.
