Abstract

UNLABELLED: Shock is a consequence of disturbed circulation and decreased blood perfusion of tissues which, on the whole, cause functional and morphological impairments of organic systems. Occurrence of shock is not high, but it is significant due to bad prognosis and high mortality rate. CLASSIFICATION: This is one of the classifications of shock: cardiogenic, extracardiogenic-obstructive, oligentic and distributive shock. PATHOPHYSIOLOGIC MECHANISMS OF SHOCK: Regardless of the cause of shock, the clinical picture is dominated by hypotension mostly caused by decrease of minute volume (septic shock may be an exception--minute volume might be high). Due to hypotension a lot of compensatory mechanisms are activated and in the beginning showing the compensatory phase of disease and if nothing is done decompensatory and in the end irreversible phase of shock occurs with fatal outcome. The clinical picture depends on the etiology of shock, type of shock, but it also has certain specificities. PROGNOSIS: The prognosis depends on the clinical picture dominated by the following symptoms: hypotension, decreased diuresis, acidosis, consciousness disorders, tachypnea, peripheral cyanosis, cold and damp skin. MANAGEMENT: These patients are managed in intensive care units, where the following parameters are followed-up: arterial pressure, central venous pressure, minute heart volume, systemic vascular resistance, diuresis, continual follow-up of heart rate, breathing and consciousness. In treatment of shock it is necessary to: normalize the circulatory volume, establish electrolyte balance, regulate glycemia and acid-base status, compensate the volume, calm the patient and alleviate pain.

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.
