Cerebral Blood Transit in Sickle Cell Anemia

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Sickle cell anemia (SCA) patients upregulate cerebral blood flow to compensate for decreased arterial oxygen content. Such hyperemic conditions can manifest as venous hyperintense signal on arterial spin labeling (ASL) MRI, which may reflect faster capillary blood transit, altered oxygen extraction fraction (OEF), and infarct risk ...

Effect of plasma exchange with albumin replacement on albumin functionality and organ dysfunction in acute-on-chronic liver failure

open access: yesJHEP Reports
Background & Aims: Effective treatments for acute-on-chronic liver failure (ACLF) are a major unmet need. This proof-of-concept pilot study was aimed at evaluating the effects of plasma exchange (PE) with albumin 5% (PE-A5%) on albumin functional ...

Acute Effects of Smoking and Vaping on Markers of Vascular Function via Quantitative MRI

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background E‐cigarettes contribute to endothelial dysfunction, a known cause of systemic atherosclerotic disease that cannot be adequately characterized by a single physiological parameter measured at a single vascular bed. Purpose/Hypothesis Quantify and compare acute effects of smoking or vaping with tobacco cigarettes (t‐cigs), nicotinized ...

Fetal Brain Abnormalities Following Laser Surgery for Twin‐to‐Twin Transfusion Syndrome: Imaging Patterns and Evolution

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Introduction Severe brain injury has been reported following fetoscopic laser ablation (FLA) for twin‐to‐twin transfusion syndrome (TTTS), but imaging patterns and temporal evolution remain poorly defined. This study aimed to characterize the progression of severe brain injury after FLA. Methods We conducted a retrospective case series of TTTS

Ophthalmic artery Doppler as potential surrogate marker of angiogenic imbalance in near‐term pregnancy

open access: yesUltrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objectives First, to evaluate whether the ratio of soluble fms‐like tyrosine kinase‐1 to placental growth factor (sFlt‐1/PlGF) is associated with hemodynamic changes in ophthalmic artery (OA) Doppler in near‐term pregnancy. Second, to assess the performance of OA Doppler to rule in and rule out angiogenic factor imbalance.

A case of fatal fulminant fat embolism syndrome saved by VA-ECMO in the acute phase of multiple trauma

open access: yesTrauma Case Reports
Fat embolism syndrome (FES) is a rare complication of long bone fractures, with fulminant FES developing within 12 h of injury and often proving fatal (Shaikh, 2009 [1]).

Maternal propranolol as a safe alternative to invasive fetal surgery in chorioangioma management

open access: yesUltrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Chorioangiomas are associated with a significant risk of fetal demise due to high‐output cardiac failure. Standard invasive treatment, including fetoscopic laser photocoagulation and intratumoral embolization, shows limited success and has high fetal mortality rates.

Validation of Aortic Blood Flow Simulations During Extracorporeal Circulation Using Phase Contrast Magnetic Resonance Imaging

open access: yesArtificial Organs, EarlyView.
This is the first study assessing in vivo blood flow profiles during extracorporeal circulation (ECC) scenarios. Magnetic resonance imaging data served for the calibration of computational fluid dynamics algorithms, enabling accurate replication of the hemodynamic conditions.

Narrative Review on Therapies That Influence Inflammatory Responses During Extremely Premature Perinatal Respiratory Transition

open access: yesActa Paediatrica, EarlyView.
ABSTRACT Aims and Methods Advances in neonatal care have extended borderline survival to 22–24 post‐conceptional weeks. Present review discusses approaches for prolonging short pregnancies and prevention of serious morbidities in extremely premature infants born before 28 weeks of pregnancy.
