Tissue plasminogen activator administration and nursing considerations.

Abstract

Intravenous thrombolytic therapy is rapidly gaining acceptance in the care of acute myocardial infarction (AMI) patients. There are several thrombolytic agents in use; however, this article will focus on tissue type plasminogen activator (t-PA). A thorough understanding of the benefits and risks associated with thrombolytic administration will be critical in the successful utilization of this form of therapy. Recent data show that infarct size is linked to mortality. In the 1980s, therapy for acute myocardial infarction patients is directed at salvaging myocardium and limiting infarct size. Prior to this, therapy consisted mainly of supportive care that resulted only in minor effects on the patients prognosis. Intracoronary thrombus has recently been recognized as the cause in most cases of acute myocardial infarction. Thrombolytic therapy represents a method of dissolving a thrombus and reestablishing blood flow to the previously occluded coronary artery. Early reperfusion of ischemic myocardial tissue can limit the amount of damage caused by evolving myocardial infarction. Intervention with thrombolytic therapy in the early hours of acute myocardial infarctions has been associated with reduction in the infarct size, improvement in left ventricular function and reduction in mortality. Nursing plays a critical role in ensuring the successful use of thrombolytic therapy by early identification of appropriate patients and accurate administration of the thrombolytic agent.

Global Genomic Surveillance.

Global genomic surveillance has emerged as a foundational pillar of public health in the twenty-first century, enabling real-time tracking of pathogen evolution and informing outbreak response. This chapter examines the strategic architecture of global genomic surveillance, focusing on its application to arboviruses such as chikungunya virus (CHIKV). It explores the integration of genomic data with epidemiological, clinical, and environmental information within a One Health framework, while addressing critical challenges in governance, equity, and interoperability. The discussion covers the entire genomic surveillance workflow, from sample collection and sequencing to bioinformatic analysis and phylogenetic inference, and highlights the transformative role of artificial intelligence (AI) in predictive surveillance. By analyzing global initiatives, operational barriers, and emerging technologies, this chapter underscores the necessity of sustainable, equitable, and interoperable genomic systems to proactively address current and future infectious disease threats.

Systematic Dissection of Key Driver Perturbation Signatures in Single Cells via ECCITE-seq.

CRISPR screens, such as expanded CRISPR-compatible cellular indexing of transcriptomes and epitopes by sequencing (ECCITE-seq), enable the simultaneous measurement of transcriptomes, gRNA identity, and cell-surface protein expression at single-cell resolution to systematically interrogate gene function. This platform provides a powerful and scalable experimental approach for validating disease-associated regulators identified by large-scale association studies and other computational methods, including network-based analyses of multi-omics data. Here, as an example application, we describe an ECCITE-seq framework to characterize the transcriptomic consequences of perturbing multiple neuronal key driver genes associated with Alzheimer's disease (AD) in human-induced pluripotent stem cell (hiPSC)-derived neurons. More broadly, by integrating customized pooled gRNA libraries with different CRISPR effectors across multiple cell types, this approach allows for the assessment of the regulatory impact of candidate genes implicated in development and disease processes.

Identification of Genome-Wide Chromatin Structural Aberration in Cancer by Hi-C Analysis.

Aberrant three-dimensional genome organization is a hallmark of cancer, often driving oncogene activation through mechanisms such as enhancer hijacking. High-throughput chromosome conformation capture (Hi-C) maps these interactions on a genome-wide scale. Unlike earlier dilution-based methods, in situ Hi-C performs proximity ligation within intact nuclei, minimizing random ligation noise and enabling fine-scale structure detection. This chapter describes an optimized in situ Hi-C protocol tailored for cancer cell lines using MboI digestion and biotin-mediated pull-down to generate high-complexity libraries. We further outline a computational workflow that extends beyond standard topological mapping of compartments and topologically associating domains to identify cancer-specific aberrations. Specifically, we focus on detecting chromosomal rearrangements (structural variants) and characterizing the distinct circular topology of extrachromosomal DNA. This integrated experimental and analytical framework provides the necessary tools to dissect the spatial dysregulation underlying tumor evolution.
