Acute ischemic stroke with large vessel occlusion (LVO) continues to present a considerable challenge to global health, marked by substantial morbidity and mortality rates. Although definitive diagnostic markers exist in the form of neuroimaging, their expense, limited availability, and potential for diagnostic delay can often result in missed opportunities for life-saving interventions. Despite several past attempts, research efforts to date have been fraught with challenges likely due to multiple factors, such as the inclusion of diverse stroke types, variable onset intervals, differing pathobiologies, and a range of infarct sizes, all contributing to inconsistent circulating biomarker levels.

Androgen-indifferent prostate cancer (AIPC) is increasingly common and particularly lethal. Data describing these tumors are sparse, and AIPC remains a poorly understood malignancy. Utilizing the Oncology Research Information Exchange Network (ORIEN) database, we enriched for tumors with features of AIPC using previously described characteristics.

Jun/JUN is a basic leucine zipper (bZIP) protein and a prototypic member of the activator protein-1 (AP-1) family of transcription factors that can act as homo- or heterodimers, interact with DNA elements and co-factors, and regulate gene transcription. Jun is expressed by both immune and inflammatory cells. Jun is traditionally seen as an oncoprotein that regulates processes involved in transformation and oncogenesis in human tumours.

RAD18 is a conserved eukaryotic E3 ubiquitin ligase that promotes genome stability through multiple pathways. One of these is gap-filling DNA synthesis at active replication forks and in post-replicative DNA. RAD18 also regulates homologous recombination (HR) repair of DNA breaks; however, the current literature describing the contribution of RAD18 to HR in mammalian systems has not reached a consensus.

Motor Learning Deficits in a Neonatal Mouse Model of Hypoxic-Ischemic Injury.

Children (Basel)

December 2024

Department of Pediatrics, Division of Neonatology, University of Virginia, Charlottesville, VA 22908, USA.

Background/objectives: Motor deficits following neonatal brain injury, from cerebral palsy to subtle deficits in motor planning, are common yet underreported. Rodent models of motor deficits in neonatal hypoxia-ischemia (HI) allow improved understanding of the underlying mechanisms and neuroprotective strategies. Our goal was to test motor performance and learning in a mouse model of neonatal HI.

Background: Accurate blood pressure monitoring is essential in many clinical scenarios for adults and children and, when continuous measurement is critical, necessitates the insertion of an arterial line. A novel continuous non-invasive arterial pressure monitoring device using a pulse contour algorithm (Pulse Decomposition Analysis), Vitalstream™, is approved by the United States Food and Drug Administration for use in adults. In this study the performance and accuracy of the device compared to intraarterial blood pressure monitoring were assessed in children ages 2-17 undergoing major surgeries.

Antinuclear antibodies (ANA) are often found in ILD; whether ANA is associated with radiographic progression of quantitive interstital lung changes is unknown. We performed longitudinal analyses of adults in the Multi-Ethnic Study of Atherosclerosis using linear mixed effects models with random intercept and slope to evaluate whether baseline ANA was associated with change in the amount of lung with high attenuation areas on CT (HAAs, percentage of imaged lung with -600 to -250 HU). In 6,638 subjects with 17,293 CT scans over 18 years, 741 (11%) were ANA positive.

The toxicokinetics of nitrosamines remain a mystery to this day, though it appears that the role of nitrosamines in potentiating the generation of mutations required for the onset of skin cancer continues to be a significant concern. Nitrosamines are mutagens, genotoxic substances, and mediators of phototoxicity/carcinogenicity, whose long-term daily usage, in the context of polypharmacy, can result in the parallel appearance of heterogeneous forms of skin cancer: keratinocytic and melanocytic. But a number of clinical observations suggest that it is the nitrosamines that potentiate the multiple occurrences of skin cancer over the years, or recurrences of skin cancer localized in areas exposed to solar radiation.

We examine the efficacy of the Individualized Coordination and Empowerment for Care Partners of Persons with Dementia (ICECaP), an intervention that involves one-on-one individualized support from a dementia care coordinator for a dementia care partner, compared to an active control group. At least once monthly contact is made from a dementia care coordinator to the dementia care partner by telephone, video conferencing, email, or in-person support at clinical visits for the person with dementia. In this pilot randomized unblinded control trial of ICECaP, n = 61 (n = 90 randomized) care partners completed 12-months of the ICECaP intervention and n = 69 (n = 92 randomized) care partners received routine clinical support (controls) in an outpatient memory care clinic at an academic medical center, from which the participants were recruited.

Although viruses subvert innate immune pathways for their replication, there is evidence they can also co-opt antiviral responses for their benefit. The ubiquitous human pathogen, Herpes simplex virus-1 (HSV-1), encodes a protein (UL12.5) that induces the release of mitochondrial nucleic acid into the cytosol, which activates immune-sensing pathways and reduces productive replication in nonneuronal cells.

The Evolving Features of Takotsubo Syndrome.

Curr Cardiol Rep

January 2025

Berne Cardiovascular Research Center and Division of Cardiology, University of Virginia, Charlottesville, USA.

Purpose Of The Review: Takotsubo syndrome (TTS) is a transient form of left ventricular dysfunction, typically affecting post-menopausal females, often preceded by emotional or physical stressful events that act as triggers. Initially believed to be a rare and benign condition for its reversible nature, TTS has recently emerged as a complex multifaceted clinical entity, with heterogenous clinical presentations and a non-negligible risk of serious in-hospital complications, including acute heart failure, arrhythmias and death.

Recent Findings: Emerging pathophysiological hypotheses, ranging from microvascular dysfunction to systemic inflammation, offer new insights into the underlying mechanisms of TTS.

A new proliferation of optical instruments that can be attached to towers over or within ecosystems, or 'proximal' remote sensing, enables a comprehensive characterization of terrestrial ecosystem structure, function, and fluxes of energy, water, and carbon. Proximal remote sensing can bridge the gap between individual plants, site-level eddy-covariance fluxes, and airborne and spaceborne remote sensing by providing continuous data at a high-spatiotemporal resolution. Here, we review recent advances in proximal remote sensing for improving our mechanistic understanding of plant and ecosystem processes, model development, and validation of current and upcoming satellite missions.
