This book discusses the organ-specific systemic manifestations of COVID-19. The initial chapters of the book review the origin and evolution of the coronaviruses, followed by pathogenesis and immune response during COVID-19 infection. The book also provides insight into the role of angiotensin-converting enzyme 2 in the onset of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogenesis. It summarizes the neurological aspects of SARS-CoV2, including transmission pathways, mechanisms of invasion into the nervous system, and mechanisms of neurological disease. It also delineates the association of severe disease with high blood plasma levels of inflammatory cytokines and inflammatory markers in SARS-CoV-2 infection. Lastly, it discusses the perturbation of gut microbiota by SARS-CoV-2 and uncovers the potential risk of virus infection on reproductive health.

Zika virus (ZIKV) is a mosquito-borne member of the Flaviviridae family that historically has been associated with mild febrile illness. However, the recent outbreaks in Brazil in 2015 and its rapid spread throughout South and Central America and the Caribbean, together with its association with severe neurological disorders—including fetal microcephaly and Guillain-Barré syndrome in adults—have changed the historic perspective of ZIKV. Currently, ZIKV is considered an important public health concern that has the potential to affect millions of people worldwide. The significance of ZIKV in human health and the lack of approved vaccines and/or antiviral drugs to combat ZIKV infection have triggered a global effort to develop effective countermeasures to prevent and/or treat ZIKV infection. In this Special Issue of Viruses, we have assembled a collection of 32 research and review articles that cover the more recent advances on ZIKV molecular biology, replication and transmission, virus–host interactions, pathogenesis, epidemiology, vaccine development, antivirals, and viral diagnosis.

A timely work describing how localized hospital-based health technology assessment (HB-HTA) complements general, ‘arms-length’ HTA agency efforts, and what has been the collective global impact of HB-HTA across the globe. While HB-HTA has gained significant momentum over the past few years, expertise in the field, and information on the operation and organization of HB-HTA, has been scattered. This book serves to bring this information together to inform those who are currently working in the field of HTA at the hospital, regional, national or global level. In addition, this book is intended for decision-makers and policy-makers with a stake in determining the uptake and decommissioning of new and established technologies in the hospital setting. HTA has traditionally been performed at the National/Regional level by HTA Agencies, typically linked to governments. Yet hospitals are the main entry door for most health technologies (HTs). Hospital decision-makers must undertake multiple high stakes investment and disinvestment decisions annually for innovative HTs, usually without adequate information. Despite the existence of arms-length HTA Agencies, inadequate information is available to hospital decision-makers either because relevant HTA reports are not yet released at the time of entry of new technologies to the field, or because even when the report exists, the information contained is insufficient to clarify the contextualized informational needs of hospital decision makers. Therefore, there has recently been a rising trend toward hospital-based HTA units and programs. These units/programs complement the work of National/Regional HTA Agencies by providing the key and relevant evidence needed by hospital decision makers in their specific hospital context, and within required decision-making timelines. The emergence of HB-HTA is creating a comprehensive HTA ecosystem across health care levels, which creates better bridges for knowledge translation through relevance and timeliness.

Annotation Recombinant viruses expressing reporter fluorescent or bioluminescent proteins are an excellent option to evaluate the dynamics of viral infection progression in both cultured cells and/or validated animal models of viral infection. Reporter proteins are valid surrogates for direct detection of infected cells in vitro and in vivo, without the use of secondary methodologies to identify infected cells. By eliminating the need of secondary labeling, tractable replicating-competent, reporter-expressing viruses provide an ideal approach to monitor viral infections in real time, representing a significant advance in the study of the biology of viruses, to evaluate vaccination approaches, and to identify new therapeutics against viral infections using high-throughput screening settings. In this Special Issue "Replication-Competent Reporter-Expressing Viruses" we review replication-competent, reporter-expressing viruses belonging to different families, methods of characterization, and applications to facilitate the study of in vitro and in vivo viral infections. We also seek to discuss disadvantages and limitations associated with these reporter-expressing viruses. Finally, we provide rational future perspectives and additional avenues for the development, characterization, and applications of recombinant, reporter-expressing, competent viruses.

This book provides a comprehensive but concise overview on the economically important emerging cattle pox virus derived Lumpy Skin Disease, including the characteristics of causative agent, description of clinical signs in cattle, pathology and histopathology, immunity, geographical distribution, epidemiology and transmission pathways, control and eradication of the disease. In addition the recent developments in vaccination, mathematical modeling and risk assessment are discussed. Lumpy Skin Disease currently spreads aggressively across the Middle and Near East. The first incursion to the European Union territory occurred in Greece in autumn 2015. The book targets clinicians and field veterinarians in Lumpy Skin Disease affected regions, veterinary authorities as well as advanced students in veterinary medicine and virology.

Mathematical modelling in biomedicine is a rapidly developing scientific discipline at the intersection of medicine, biology, mathematics, physics, and computer science. Its progress is stimulated by fundamental scientific questions and by the applications to public health. This book represents a collection of papers devoted to mathematical modelling of various physiological problems in normal and pathological conditions. It covers a broad range of topics including cardiovascular system and diseases, heart and brain modelling, tumor growth, viral infections, and immune response. Computational models of blood circulation are used to study the influence of heart arrhythmias on coronary blood flow and on operating modes for left-ventricle-assisted devices. Wave propagation in the cardiac tissue is investigated in order to show the influence of tissue heterogeneity and fibrosis. The models of tumor growth are used to determine optimal protocols of antiangiogenic and radiotherapy. The models of viral hepatitis kinetics are considered for the parameter identification, and the evolution of viral quasi-species is investigated. The book presents the state-of-the-art in mathematical modelling in biomedicine and opens new perspectives in this passionate field of research.

First systematic treatment of best-worst scaling, explaining how to implement, analyze, and apply the theory across a range of disciplines.
