Pregnancy is a vulnerable time with significant cardiovascular changes that can lead to adverse outcomes, which can extend into the postpartum window. Exposure to emissions from electronic cigarettes (Ecig), commonly known as "vaping," has an adverse impact on cardiovascular function during pregnancy and post-natal life of offspring, but the postpartum effects on maternal health are poorly understood. We used a Sprague Dawley rat model, where pregnant dams are exposed to Ecigs between gestational day (GD)2-GD21 to examine postpartum consequences.

Transthyretin Cardiac Amyloidosis: Current and Emerging Therapies.

Curr Cardiol Rep

January 2025

The Pauley Heart Center, Virginia Commonwealth University, 1200 East Broad Street West Hospital, 8th Floor, West Wing, Richmond, VA, 23231, USA.

Purpose Of Review: In this article, we describe current and newer TTR stabilizers, TTR silencers which include small interfering RNA agents (siRNA), antisense oligonucleotides (ASO) and CRISPR-Cas9 gene editing, and TTR depleters, which investigates the use of monoclonal antibodies to remove amyloid fibril deposits for patients with advanced disease.

Recent Findings: Once thought to be a rare and fatal condition, increased recognition, improved non-invasive diagnostic tools, and the explosive development of novel therapies, has transformed the landscape of transthyretin amyloid cardiomyopathy (ATTR-CM). Advances in cardiac imaging with respect to echocardiography, cardiac magnetic resonance imaging (CMR), and radionuclide bone scintigraphy has increased the diagnosis of ATTR-CM over the last twenty years.

Variational Quantum Algorithm for Non-Markovian Quantum Dynamics Using an Ensemble of Ehrenfest Trajectories.

J Phys Chem Lett

January 2025

Department of Chemistry and Biochemistry, George Mason University, Fairfax, Virginia 22030, United States.

The simulation of non-Markovian quantum dynamics plays an important role in the understanding of charge and exciton dynamics in the condensed phase environment, yet such a simulation remains computationally expensive on classical computers. In this work, we develop a variational quantum algorithm that is capable of simulating non-Markovian quantum dynamics on quantum computers. The algorithm captures the non-Markovian effect by employing the Ehrenfest trajectories and Monte Carlo sampling of their thermal distribution.

Partial oxidation of ethylene over silver catalysts produces more than 30 million metric tons of ethylene oxide (EO) annually. However, the form of active silver surfaces, reactive oxygen species, and dominant pathways of this chemical reaction remains controversial despite decades of research. Here, we use Raman spectroscopy and transient kinetic measurements to demonstrate that higher coverages of peroxide species, present only upon Ag oxide surfaces that form , correlate with greater selectivities to EO.

Problem Research Strategy And Findings: The 1968 Fair Housing Act required local government recipients of federal money to take meaningful actions to affirmatively further fair housing (AFFH). Current fair housing analysis requirements are copious but do not request an assessment of how land use policies affect the potential for neighborhood integration. A recent California law requires local governments to include AFFH analysis in existing planning processes, and state guidelines encourage the measurement of the spatial distribution of planned sites for low-income housing with respect to opportunity.

Prone Transpsoas Lumbar Interbody Fusion for Degenerative Disc Disease.

JBJS Essent Surg Tech

January 2025

Department of Neurosurgery, Center for Neuroscience and Spine, Virginia Mason Medical Center, Seattle, Washington.

Background: Prone transpsoas lumbar interbody fusion (PTP) is a newer technique to treat various spinal disc pathologies. PTP is a variation of lateral lumbar interbody fusion (LLIF) that is performed with the patient prone rather than in the lateral decubitus position. This approach offers similar benefits of lateral spinal surgery, which include less blood loss, shorter hospital stay, and quicker recovery compared with traditional open spine surgery.

We examined whether neighborhood-level socioeconomic disadvantage per the Area Deprivation Index (ADI) was associated with maternal cardiovascular health (CVH) in early pregnancy per the American Heart Association Life's Essential 8 (LE8). This is a cross-sectional analysis from the prospective Nulliparous Pregnancy Outcomes Study-Monitoring Mothers-to-Be Heart Health Study (nuMoM2b-HHS) cohort. The exposure was the ADI in tertiles (T) from least (T1) to most (T3) socioeconomic disadvantage.

Background: Extrahepatic Common Bile Duct Obstruction (EHBDO) is a serious condition that requires accurate diagnosis for effective treatment. Magnetic Resonance Cholangiopancreatography (MRCP) is a widely used noninvasive imaging technique for visualizing bile ducts, but its interpretation can be complex.

Objective: This study aimed to develop a deep learning-based classification model that integrates MRCP images and clinical parameters to assist radiologists in diagnosing EHBDO more accurately.

Engineered nanomaterials (ENM) are capable of crossing the placental barrier and accumulating in fetal tissue. Specifically, the ENM nano-titanium dioxide (nano-TiO), has been shown to accumulate in placental and fetal tissue, resulting in decreased birthweight in pups. Additionally, nano-TiO is an established cardiac toxicant and regulator of glucose homeostasis, and exposure in utero may lead to serious maladaptive responses in cardiac development and overall metabolism.

January 2025

Author Affiliations: School of Nutrition and Food Sciences, Louisiana State University (LSU) & LSU Agricultural Center, Baton Rouge, Louisiana (Dr Houghtaling, Ms Pradhananga, and Dr Holston); Department of Human Nutrition, Foods, and Exercise, Virginia Tech, Blacksburg, Virginia (Dr Houghtaling); Center for Nutrition & Health Impact, Omaha, Nebraska (Drs Houghtaling and Balis); and Agricultural and Extension Education and Evaluation, Louisiana State University (LSU) & LSU Agricultural Center, Baton Rouge, Louisiana (Dr Cater).

Context: The National Cooperative Extension System is a leader in delivering healthy eating and active living (HEAL) policy, systems, and environmental (PSE) changes; however, these interventions are challenging, and technical assistance efforts often misalign with implementation science concepts.

Objective: The study objective was to understand the importance of implementation strategies and tailoring needs to support Louisiana Nutrition and Community Health (NCH) practitioners' delivery of rural HEAL PSE changes.

Design: An explanatory sequential mixed method study design was used, including a survey to rank the importance of implementation strategies for HEAL PSE changes and a follow-up interview.

Hidradenitis suppurativa (HS) patients treated with tumor necrosis factor (TNF) inhibitors are at an increased risk for tuberculosis (TB) reactivation, necessitating baseline latent TB infection (LTBI) screening. However, evidence regarding the value of periodic LTBI screening in this population is limited. In this single-center retrospective chart review, we investigated the LTBI rate in HS patients treated with adalimumab or infliximab.

Ternary stochastic neuron- implemented with a single strained magnetostrictive nanomagnet.

Nanotechnology

January 2025

Department of Electrical and Computer Engineering, Virginia Commonwealth University, Richmond, VA 23284, United States of America.

Stochastic neurons are extremely efficient hardware for solving a large class of problems and usually come in two varieties - 'binary' where the neuronal state varies randomly between two values of ±1 and 'analog' where the neuronal state can randomly assume any value between -1 and +1. Both have their uses in neuromorphic computing and both can be implemented with low- or zero-energy-barrier nanomagnets whose random magnetization orientations in the presence of thermal noise encode the binary or analog state variables. In between these two classes is-ary stochastic neurons, mainly ternary stochastic neurons (TSNs) whose state randomly assumes one of three values (-1,0,+1), which have proved to be efficient in pattern classification tasks such as recognizing handwritten digits from the MNIST data set or patterns from the CIFAR-10 data set.
