Otovent Versus Valsalva: Physiological Insights for Diagnostic and Therapeutic Autoinflation in Eustachian Tube Dysfunction

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objectives Autoinflation aids assessment of Eustachian tube function, or as a conservative treatment for obstructive Eustachian tube dysfunction. This study compares the physiological characteristics of 2 autoinflation techniques, the Otovent® device and the Valsalva manoeuvre, to inform clinical application for both diagnosis and therapy ...

Microbubble‐Based Ultrasound Contrast Agents in Contrast‐Enhanced Ultrasonography for Managing Portal Hypertension in Cirrhosis

Portal Hypertension &Cirrhosis, EarlyView.
As the hepatic venous pressure gradient (HVPG) remains the current gold standard for diagnosing portal hypertension in cirrhosis, its clinical application is limited by invasiveness, high cost, and restricted availability. Given the urgent need for noninvasive techniques to dynamically monitor portal vein pressure (PVP), contrast‐enhanced ...

Camels as a Climate‐Resilient Linchpin for Sustainable Development in Global Drylands

Sustainable Development, EarlyView.
ABSTRACT Camels represent a significant, yet underutilized, asset for advancing integrated sustainable development in the world's expanding drylands. Previous reviews have examined camels' physiology, milk composition, or pastoral systems in isolation; this review examines their potential as a climate‐resilient linchpin for food systems by synthesizing
