Hyperoxia-induced deterioration of diastolic function in anaesthetised patients with coronary artery disease – Randomised crossover trial

BJA Open, 2023
Background: There are no current recommendations for oxygen titration in patients with stable coronary artery disease. This study investigates the effect of iatrogenic hyperoxia on cardiac function in patients with coronary artery disease undergoing ...

Human Umbilical Cord Mesenchymal Stem Cell‐Derived Microvesicles Alleviate Bronchopulmonary Dysplasia in Preterm Rats by Inhibiting Neutrophil Extracellular Trap Formation

Pediatric Discovery, EarlyView.
Excessive neutrophil extracellular trap (NET) extrusion (NETosis) links prenatal inflammation to bronchopulmonary dysplasia (BPD) pathogenesis. Treatment with human umbilical cord mesenchymal stem cell‐derived microvesicles suppresses NET formation, reduces lung injury, and promotes alveolarization in a preterm rat model, offering a promising cell‐free

Type I interferon overactivation in sera of patients with anti‐MDA5‐positive dermatomyositis‐associated interstitial lung disease

Rheumatology &Autoimmunity, EarlyView.
Sera from patients with anti‐MDA5‐positive dermatomyositis‐associated interstitial lung disease (ILD) exhibit significantly higher type I interferon (IFN‐I) bioactivity and interferon‐stimulated gene‐inducing activity compared to anti‐ARS‐positive ILD and healthy controls.

Update on the Pathophysiology, Aetiology and Management of Central Sleep Apnoea

Respirology, EarlyView.
ABSTRACT Central sleep apnoea (CSA) of the periodic breathing type occurs during the transition between wakefulness and stage 1 and 2 non‐REM sleep. In adults at sea level, it occurs most commonly due to advanced heart failure (HF) or chronic opioid use and in ~5% of obstructive sleep apnoea patients initiating CPAP.

Hemodynamic Effects of Prolonged Apneic Oxygenation in Laryngologic Surgery: A Randomized Controlled Pilot Trial

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Limited data exist on cardiocirculatory responses associated with extended periods of apnea during administration of high‐flow nasal oxygen for laryngologic surgery (apneic oxygenation with HFNO, AO‐HFNO). The possibility of hemodynamic compromise in the settings of acute hypercapnia, respiratory acidosis, hyperoxia, and IV ...

Extracellular Signal-Regulated Kinase 1 Alone Is Dispensable for Hyperoxia-Mediated Alveolar and Pulmonary Vascular Simplification in Neonatal Mice

Antioxidants, 2022
Bronchopulmonary dysplasia (BPD) is a morbid lung disease distinguished by lung alveolar and vascular simplification. Hyperoxia, an important BPD causative factor, increases extracellular signal-regulated kinases (ERK)-1/2 expression, whereas decreased ...

Impact of Respiratory Support Strategies on CO2 Variability During Therapeutic Hypothermia in Neonates With Asphyxia: Data From the German Hypothermia Registry

Acta Paediatrica, EarlyView.
ABSTRACT Aim To evaluate associations between respiratory support strategies, partial pressure of carbon dioxide (pCO2) variability and oxygen exposure in neonates with hypoxic–ischaemic encephalopathy (HIE) undergoing therapeutic hypothermia (TH). Methods This retrospective multicentre study used data from the German Hypothermia Registry, including ...

CD93—An emerging vascular target in cancer therapy

British Journal of Pharmacology, EarlyView.
Abstract CD93 is a single‐pass transmembrane glycoprotein that belongs to the C‐type lectin domain group XIV family of proteins. Although it is known to be expressed in other cell types, namely, in some subsets of immune cells, CD93 is primarily expressed on endothelial cells, where it acts as a crucial regulator of angiogenesis.

TXNIP mediates ferroptosis in a bronchopulmonary dysplasia mouse model by regulating the SLC7A11/GPX4 pathway

Scientific Reports
Bronchopulmonary dysplasia (BPD) is one of the most common respiratory diseases in preterm infants. Studies have shown that ferroptosis is involved in the pathogenesis of BPD, and thioredoxin-interacting protein (TXNIP)-mediated oxidative stress also ...
