Relationship between high VExUS score and echocardiographic parameters: a systematic review and meta-analysis

open access: yesJournal of Anesthesia, Analgesia and Critical Care
Background The Venous Excess Ultrasound (VExUS) score integrates inferior vena cava diameter and venous Doppler findings to quantify congestion. Findings are conflicting regarding whether higher VExUS grades reflect worse cardiac function. We conducted a

Ahcy Acts as an Effector of Hnf4a‐Driven Super‐Enhancer Activation to Alleviate MASLD During Intermittent Fasting

open access: yesAdvanced Science, EarlyView.
Our study identifies an Hnf4a‐driven super‐enhancer of hepatic Ahcy that mediates the protective effects of intermittent fasting against MASLD. Disruption of the Ahcy super‐enhancer reduces Ahcy expression and exacerbates lipid accumulation. This pathway prevents aberrant promoter hypermethylation by maintaining the SAM/SAH balance, as exemplified by ...

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

open access: yesAdvanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...

Assessing venous congestion in critical illness: advantages of the inferior vena cava shape change index over diameter

open access: yesAnnals of Intensive Care
Background: The traditional Venous Excess Ultrasound (VExUS) scoring system relies on inferior vena cava (IVC) diameter measurements, which are affected by multiple confounding factors.

Copper‐Doped Prussian Blue Nanozymes With Hyaluronic Acid‐Mediated Targeting Alleviate Oxidative Stress and Regulate Cholesterol Handling for Atherosclerosis Therapy

open access: yesAdvanced Science, EarlyView.
CuPB@HA is a CD44‐associated, plaque‐targeted nanozyme that alleviates oxidative stress, inflammation, and lipid accumulation in macrophages. By reducing CD36‐dependent lipid uptake and promoting ABCA1/ABCG1‐mediated cholesterol handling, it improves macrophage function, preferentially accumulates in atherosclerotic lesions, reduces plaque burden, and ...

The Diagnostic Accuracy of High Resolution Ultrasound Imaging for Detection of Secondary Hyperparathyroidism in Patients with Chronic Renal Failure [PDF]

open access: yes
Ultrasound is one of the preferred modalities for evaluation of the parathyroid glands. This study was undertaken to determine the accuracy of high resolution ultrasound for secondary hyperparathyroidism in patients with chronic renal failure. From March

Engineering Morphological Anisotropy to Control the In Vivo Transport Dynamics, Clearance, and Biodistribution of Silica Nanocarriers

open access: yesAdvanced Science, EarlyView.
Morphological anisotropy directs the in vivo transport under physiological flow and clearance of silica nanocarriers. Increasing anisotropy reduces cellular uptake, suppresses hepatic and splenic sequestration, and prolongs systemic circulation by steering particles toward the central flow core.
