Streamlined Analysis of Maternal Plasma Indicates Small Extracellular Vesicles are Significantly Elevated in Early-Onset Preeclampsia.

Preeclampsia (PE) is a leading cause of maternal and fetal mortality and morbidity. While placental dysfunction is a core underlying issue, the pathogenesis of this disorder is thought to differ between early-onset (EOPE) and late-onset (LOPE) subtypes. As recent reports suggest that small extracellular vesicles (sEVs) contribute to the development of PE, we have compared systemic sEV concentrations between normotensive, EOPE, and LOPE pregnancies.

Addressing cortex dysregulation in youth through brain health check coaching and prophylactic brain development.

The Carter Center has estimated that the addiction crisis in the United States (US), if continues to worsen at the same rate, may cost the country approximately 16 trillion dollars by 2030. In recent years, the well-being of youth has been compromised by not only the coronavirus disease 2019 pandemic but also the alarming global opioid crisis, particularly in the US. Each year, deadly opioid drugs claim hundreds of thousands of lives, contributing to an ever-rising death toll.

Using DFT on ultrasound measurements to determine patient-specific blood flow boundary conditions for computational hemodynamics of intracranial aneurysms.

Boundary conditions (BCs) is one pivotal factor influencing the accuracy of hemodynamic predictions on intracranial aneurysms (IAs) using computational fluid dynamics (CFD) modeling. Unfortunately, a standard procedure to secure accurate BCs for hemodynamic modeling does not exist. To bridge such a knowledge gap, two representative patient-specific IA models (Case-I and Case-II) were reconstructed and their blood flow velocity waveforms in the internal carotid artery (ICA) were measured by ultrasonic techniques and modeled by discrete Fourier transform (DFT).

A Case of Reverse Takotsubo Cardiomyopathy After Administering a Local Anesthetic Containing Epinephrine.

Takotsubo cardiomyopathy (TCM) is a rare syndrome characterized by acute and transient distinctive wall motion abnormalities accompanied by other defined objective findings. There are many variants of TCM, including the reverse (or basal) subtype. While the pathogenesis is not fully understood, both endogenous and exogenous catecholamines have been implicated.

Wound Fluid Extracellular Microvesicles: A Potential Innovative Biomarker for Wound Healing.

Background: Extracellular vesicles, or microvesicles, are a large family of membrane-bound fluid-filled sacs that cells release into the extracellular environment. Extracellular microvesicles (EMVs) are essential for cell-to-cell communications that promote wound healing. We hypothesize a correlation between the concentration of EMVs in wound fluid and the percentage of wound healing in treated chronic, nonhealing, wounds.

QTc Interval: A frequently unrecognized electrocardiographic interval.

The QT interval, an electrocardiographic temporal representation of the ventricular depolarization and repolarization, is an integral parameter that must be carefully evaluated to gather critical information regarding electrical instability that may cause malignant ventricular dysrhythmias or sudden cardiac death. The QT interval is affected by several inheritable and acquired factors, such as genetic mutations, electrolyte disturbances, and medication interactions. We strongly believe that prompt and accurate recognition of any QT interval abnormalities is critical in many clinical settings.

Real-Time Electronic Patient Portal Use Among Emergency Department Patients.

Importance: Patients with inequitable access to patient portals frequently present to emergency departments (EDs) for care. Little is known about portal use patterns among ED patients.

Objectives: To describe real-time patient portal usage trends among ED patients and compare demographic and clinical characteristics between portal users and nonusers.
