Novel imaging and blood biomarkers in acute aortic syndrome [PDF]

open access: yes, 2022
BACKGROUND: Acute aortic syndrome is an unpredictable and catastrophic condition. It is characterised by medial degeneration which is beyond the resolution of conventional anatomical imaging.

Soft, Multi‐Wavelength Photoplethysmography Enables Reliable Neonatal Blood Pressure Monitoring Via Error Stratification

open access: yesAdvanced Science, EarlyView.
A soft hybrid multi‐wavelength PPG wearable acquires neonatal signals. Synchronized PPG and invasive ABP data are segmented into fixed windows. A 1D‐EfficientNet model predicts segment‐level SBP and DBP. Model performance is examined with retrospective subgroup analysis across acquisition conditions.

Impact of D-Dimers on the Differential Diagnosis of Acute Chest Pain: Current Aspects besides the Widely Known

open access: yesClinical Medicine Insights: Cardiology, 2014
D-dimers are cleavage products of fibrin that occur during plasmin-mediated fibrinolysis of blood clots. In the emergency department, D-dimer measurement represents a valuable and cost-effective tool in the differential diagnosis of acute chest pain ...

Atypical presentation of subclavian steal syndrome with left sided sensorineural deafness

open access: yesJournal of Vascular Surgery Cases and Innovative Techniques, 2023
We present a rare manifestation of a common pathology: left sided sensorineural hearing loss secondary to subclavian steal syndrome after thoracic endovascular aortic repair for complicated acute aortic dissection.

Senkyunolide I Inhibits mtDNA‐cGAS‐STING Signaling in Macrophages via Targeting VDAC1 Oligomerization to Attenuate Ulcerative Colitis

open access: yesAdvanced Science, EarlyView.
In macrophages, senkyunolide I (SEI) directly targets the K12 residue of VDAC1 to inhibit its stress‐induced oligomerization, a critical upstream event that effectively prevents mitochondrial DNA release and subsequent cGAS‐STING pathway activation.

Acute type B aortic dissection in a pregnant woman with undiagnosed Marfan syndrome: A case report and review of the literature

open access: yesCase Reports in Women's Health, 2021
Aortic dissection during pregnancy is rare but can be life-threatening to both the mother and the foetus. Marfan syndrome is a major risk factor for acute aortic dissection during pregnancy. Here, we present the case of a woman who had not been diagnosed

Gastric pseudoaneurysm in the setting of Loey’s Dietz Syndrome [PDF]

open access: yes, 2012
Loey’s Dietz syndrome is a disorder of connective tissue caused by a mutation in the genes that encode transforming growth factor (TGF) beta receptor 1 and 2.

KLF5 Downregulation Links Impaired BNIP3‐Mediated Mitophagy to Inflammatory Valve Remodeling in Calcific Aortic Valve Disease

open access: yesAdvanced Science, EarlyView.
In human CAVD, KLF5 is reduced in VIC‐rich regions and remodeling/stress‐associated VIC states. In VICs, KLF5 sustains BNIP3 promoter activity and BNIP3‐mediated mitophagy, thereby limiting cytosolic mtDNA accumulation. KLF5 loss weakens mitochondrial quality control and enhances mtDNA‐sensitive STING/NF‐κB/NLRP3 inflammatory signaling under osteogenic

Type B aortic dissection in Marfan patients after the David procedure: Insights from patient-specific simulationCentral MessagePerspective

open access: yesJTCVS Open
Objective: An elevated risk of acute type B aortic dissection exists in patients with Marfan syndrome after the David procedure. This study explores hemodynamic changes in the descending aorta postsurgery.

Increased Disarray of Extracellular Matrix Collagen‐I Fiber Network and Compromised Biomechanics in Aortae From Marfan‐Syndrome Mice Assessed Through Combined Opto‐Biomechatronics

open access: yesAdvanced Science, EarlyView.
Combined structure‐function assessment in aortic rings from Marfan mice using MechaMorph Opto‐Biomechatronics technology relates increased elasticity (stiffness) and dynamic viscosity and less ordered extracellular matrix 3D‐structure (collagen) as potential causes for impaired Windkessel function and compromised haemodynamics in Marfan's syndrome ...
