Activin Signaling Inhibitors in Pulmonary Hypertension: A State‐of‐the‐Art Review

Pulmonary Circulation, Volume 16, Issue 3, July 2026.
ABSTRACT Pulmonary arterial hypertension (PAH) is a disease of abnormal pulmonary vascular remodeling and vascular obliteration that results in right heart failure and death. PAH pathogenesis is strongly associated with mutations of the Transforming Growth Factor Beta (TGF‐β) superfamily signaling pathway, which has previously been challenging to ...

Prognostic Value of Right Atrial Adverse Remodeling in Patients With Pulmonary Arterial Hypertension

Pulmonary Circulation, Volume 16, Issue 3, July 2026.
ABSTRACT Assessment of right atrial (RA) structure helps monitor right heart (RH) function, critical for prognosis in pulmonary arterial hypertension (PAH). This study aims to assess the prognostic value of RA adverse remodeling (RAAR) with targeted therapy in PAH. Patients diagnosed with PAH between June 2013 and June 2024 were prospectively recruited.

Effectiveness of Nurse‐Led atrial Fibrillation Detection for Patients With Embolic Stroke of Unknown Source in Stroke Units: A Retrospective Study

Nursing in Critical Care, Volume 31, Issue 4, July 2026.
ABSTRACT Background Atrial fibrillation is a primary cause of ischemic stroke, necessitating early detection, particularly in patients with embolic stroke of undetermined source. While nurseled continuous electrocardiogram monitoring allows real‐time rhythm assessment in acute stroke units, its specific clinical impact remains insufficiently clarified.

High‐Power Surgical Laser for Treatment of Oral Manifestations of Mucopolysaccharidosis VI: A Case Report

Special Care in Dentistry, Volume 46, Issue 4, July/August 2026.
ABSTRACT Mucopolysaccharidosis type VI (MPS VI), a rare metabolic disorder, results from glycosaminoglycan accumulation in tissues, frequently leading to hyperplastic gingival alterations that necessitate comprehensive intervention. An 11‐year‐old male patient diagnosed with MPS VI required hospitalization due to complications associated with a ...

A comparison of survival rate and overdrainage rate between pressure-regulated and flow-regulated ventriculoperitoneal shunt valves for the management of hydrocephalus in the first year of life

Egyptian Journal of Neurosurgery
Introduction Ventriculoperitoneal shunts are a common treatment of hydrocephalus in the first year of life; shunts can be fitted with pressure- regulated valves or flow-regulated valves.

Branch retinal artery occlusion due to patent foramen ovale in a teenager

Experimental Physiology, Volume 111, Issue 7, Page 3173-3178, 1 July 2026.
Abstract This report demonstrates the diagnostic evaluation and clinical management of a 16‐year‐old girl who developed branch retinal artery occlusion secondary to patent foramen ovale. The goal is to increase awareness of this rare presentation in adolescents among clinicians, with a summary of the important clinical features, multimodal imaging ...

An Integrated Lumped Parameter Model and Computational Fluid Dynamics Framework for Predicting Hemodynamic Parameters in Pulmonary Vein Stenosis

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
This work presents a novel computational simulation framework for the study of pulmonary venous hemodynamics that integrates a closed‐loop lumped parameter model (LPM) of the cardiovascular system with a computational fluid dynamics (CFD) model of the pulmonary veins and left atrium. Coupling of the LPM and CFD models was accomplished through surrogate

Household magnets can change the programmable shunt valve in hydrocephalus patients

, 2005
We found that external household magnets can change the pressure settings of programmable shunt valves. We compare two popular, adjustable, shunt valves used to regulate the cerebral-spinal fluid (CSF) of hydrocephalus patients: the Codman®Hakim ...
