Survival data analysis is a very broad field of statistics, encompassing a large variety of methods used in a wide range of applications, and in particular in medical research. During the last twenty years, several extensions of "classical" survival models have been developed to address particular situations often encountered in practice. This book aims to gather in a single reference the most commonly used extensions, such as frailty models (in case of unobserved heterogeneity or clustered data), cure models (when a fraction of the population will not experience the event of interest), competing risk models (in case of different types of event), and joint survival models for a time-to-event endpoint and a longitudinal outcome. Features Presents state-of-the art approaches for different advanced survival models including frailty models, cure models, competing risk models and joint models for a longitudinal and a survival outcome Uses consistent notation throughout the book for the different techniques presented Explains in which situation each of these models should be used, and how they are linked to specific research questions Focuses on the understanding of the models, their implementation, and their interpretation, with an appropriate level of methodological development for masters students and applied statisticians Provides references to existing R packages and SAS procedure or macros, and illustrates the use of the main ones on real datasets This book is primarily aimed at applied statisticians and graduate students of statistics and biostatistics. It can also serve as an introductory reference for methodological researchers interested in the main extensions of classical survival analysis.

Structural equation modeling (SEM) is a very general and flexible multivariate technique that allows relationships among variables to be examined. The roots of SEM are in the social sciences. In writing this textbook, the authors look to make SEM accessible to a wider audience of researchers across many disciplines, addressing issues unique to health and medicine. SEM is often used in practice to model and test hypothesized causal relationships among observed and latent (unobserved) variables, including in analysis across time and groups. It can be viewed as the merging of a conceptual model, path diagram, confirmatory factor analysis, and path analysis. In this textbook the authors also discuss techniques, such as mixture modeling, that expand the capacity of SEM using a combination of both continuous and categorical latent variables. Features: Basic, intermediate, and advanced SEM topics Detailed applications, particularly relevant for health and medical scientists Topics and examples that are pertinent to both new and experienced SEM researchers Substantive issues in health and medicine in the context of SEM Both methodological and applied examples Numerous figures and diagrams to illustrate the examples As SEM experts situated among clinicians and multidisciplinary researchers in medical settings, the authors provide a broad, current, on the ground understanding of the issues faced by clinical and health services researchers and decision scientists. This book gives health and medical researchers the tools to apply SEM approaches to study complex relationships between clinical measurements, individual and community-level characteristics, and patient-reported scales.

This stimulating book has become a go-to text for understanding the role that social factors play in the experience of health and many diseases. This extensively revised and updated third edition offers the most compelling case yet that stress, poverty, unhealthy lifestyles, and unpleasant living and working conditions can all be directly associated with illness. The book continues to build on the paradigm shift that has been emerging in twenty-first-century medical sociology, which looks beyond individual explanations for health and disease. As the field has headed toward a fundamentally different orientation, William Cockerham's work has been at the forefront of these changes, and he here marshals evidence and theory for those seeking a clear and authoritative guide to the realities of the social determinants of health. Of particular note in the latest edition is new material on the relationship between gender and health, implications of the life course for health behavior, the health effects of social capital, and the emergence of COVID-19. This engaging introduction to social epidemiology will be indispensable reading for all students and scholars of medical sociology, especially those with the courage to confront the possibility that society really does make people sick.

This book provides a groundbreaking introduction to the likelihood inference for correlated survival data via the hierarchical (or h-) likelihood in order to obtain the (marginal) likelihood and to address the computational difficulties in inferences and extensions. The approach presented in the book overcomes shortcomings in the traditional likelihood-based methods for clustered survival data such as intractable integration. The text includes technical materials such as derivations and proofs in each chapter, as well as recently developed software programs in R ("frailtyHL"), while the real-world data examples together with an R package, "frailtyHL" in CRAN, provide readers with useful hands-on tools. Reviewing new developments since the introduction of the h-likelihood to survival analysis (methods for interval estimation of the individual frailty and for variable selection of the fixed effects in the general class of frailty models) and guiding future directions, the book is of interest to researchers in medical and genetics fields, graduate students, and PhD (bio) statisticians.

"This very informative book introduces classical and novel statistical methods that can be used by theoretical and applied biostatisticians to develop efficient solutions for real-world problems encountered in clinical trials and epidemiological studies. The authors provide a detailed discussion of methodological and applied issues in parametric, semi-parametric and nonparametric approaches, including computationally extensive data-driven techniques, such as empirical likelihood, sequential procedures, and bootstrap methods. Many of these techniques are implemented using popular software such as R and SAS."- Vlad Dragalin, Professor, Johnson and Johnson, Spring House, PA "It is always a pleasure to come across a new book that covers nearly all facets of a branch of science one thought was so broad, so diverse, and so dynamic that no single book could possibly hope to capture all of the fundamentals as well as directions of the field. The topics within the book's purview-fundamentals of measure-theoretic probability; parametric and non-parametric statistical inference; central limit theorems; basics of martingale theory; Monte Carlo methods; sequential analysis; sequential change-point detection-are all covered with inspiring clarity and precision. The authors are also very thorough and avail themselves of the most recent scholarship. They provide a detailed account of the state of the art, and bring together results that were previously scattered across disparate disciplines. This makes the book more than just a textbook: it is a panoramic companion to the field of Biostatistics. The book is self-contained, and the concise but careful exposition of material makes it accessible to a wide audience. This is appealing to graduate students interested in getting into the field, and also to professors looking to design a course on the subject." - Aleksey S. Polunchenko, Department of Mathematical Sciences, State University of New York at Binghamton This book should be appropriate for use both as a text and as a reference. This book delivers a "ready-to-go" well-structured product to be employed in developing advanced courses. In this book the readers can find classical and new theoretical methods, open problems and new procedures. The book presents biostatistical results that are novel to the current set of books on the market and results that are even new with respect to the modern scientific literature. Several of these results can be found only in this book.

The Plague Years collects scholarly and essayistic reflections on literary, visual, and sonic representations of the COVID-19 and other pandemics. These are placed alongside poetry and short fiction written in the first two years of quarantine or isolation. This range expresses the intellectual and imaginative struggle and ingenuity entailed in coming to terms with the rampant spread of disease and its emotional, cultural, and political consequences. The contributions are from diverse contexts: Africa (from Egypt to South Africa), China, Japan, the US, and Scandinavia. They consider some of the array of contemporary engagements: poems translated from Mandarin about the traumas of the frontline, Chinese calligraphic poetry printed on cartons of PPE, comments on the literary history of representing epidemics and pandemics, political analyses of the post-truth present, and the role of life-writing and gaming in an interrupted world. Given the generative and creative obliquity of many of its parts, this collection shifts how one thinks about the diseased present and the archival pasts on which it draws. The chapters in this book were originally published as a special issue of English Studies in Africa.

Science abounds with problems where the data are noisy and the answer is not a straight line. Semiparametric regression analysis helps make sense of such data in application areas that include engineering, finance, medicine and public health. The book is geared towards researchers and professionals with little background in regression as well as statistically oriented scientists (biostatisticians, econometricians, quantitative social scientists, and epidemiologists) with knowledge of regression and the desire to begin using more flexible semiparametric models.

The disability-adjusted life year (DALY) is a generic measure of health effect that can be used in cost-effectiveness analysis as an alternative to the quality-adjusted life year (QALY). Infectious diseases are one of the major to cause significant losses of DALY and QALY. Human infectious diseases are disorders that are triggered by the micro-organisms such as bacteria, fungi, viruses, or parasites. The majority of such diseases are contagious and create a public health menace. There are several reasons why infectious diseases are deadly diseases, and one of the primary reasons is the drug resistance developed over time. Drug resistance-associated mutations are linked to increasing drug efflux, modifications of the drugs, or their targets. Every year, new drugs are being approved by FDA to treat infectious diseases. Nonetheless, the infectious diseases will undoubtedly persist as permanent and main threats to humanity for now and in the future. A total of four books are covered under the series of Infectious drug diseases. - Malarial drug delivery systems - Tubercular drug delivery systems - Viral drug delivery systems - Infectious disease drug delivery systems Infectious diseases are the world’s greatest killers that present one of the most significant health and security challenges. Humans have lived with emerging and re-emerging pathogens since before the documented history of civilization. The only determining fact today is - If the situation is “worse” or “better” than in past. The answer is probably “worse”, may be due significant increase in human population, increased cross-continent mobility, imbalanced (stressed) life style, irregular food habits leading to compromised innate immunity and over or under practiced hygiene routine. When the incidence of such a disease in people increases over 20 years or threatens to increase, it is called an “emerging” disease, and a growing number have made watch lists and headlines in nearly every country -like highly pathogenic H5N1 avian influenza, severe acute respiratory syndrome (SARS), Ebola virus, food- and waterborne illnesses, and a range of antimicrobial-resistant bacterial diseases TB. This book addresses current and new therapy developments in treating such infectious diseases, updates on finding new drugs, identification of innovative diagnostic methods, understanding of disease research models and clinical trials performances of new treatment modalities. Audiences from a broad range of groups, from researchers, academicians, and public health bodies to regulatory experts, can benefit from the compiled information to learn more about patient needs and current research advances in the field of infectious diseases and related research.

The COVID-19 pandemic has disproportionately affected communities of color while highlighting the prevalence of structural racism in the United States. This crucial collection of essays, written by leading scholars from the fields of communications, political science, health, philosophy, and geography, explores the manifold ways in which the COVID-19 pandemic has impacted upon Black, Latinx, and Indigenous communities and the way we see race relations in the United States. The COVID-19 pandemic has exposed the significance of U.S. health inequalities, which the World Health Organization defines as "avoidable [and] unfair." It has also highlighted structural racism, specifically, institutions, practices, values, customs, and policies that differentially allocate resources and opportunities so as to increase inequity among racial groups. Navarro and Hernandez therefore argue that the COVID-19 pandemic has unleashed a race war in America that has further marginalized communities of color by limiting access to resources by different racial and ethnic minorities, particularly women within these communities. Moreover, the systemic policies of the past that upheld or failed to address the unequal social conditions affecting Blacks, Latinxs, and other minorities have now been magnified with COVID-19. The volume concludes by offering recommendations to prevent future humanitarian crises from exacerbating racial divisions and having a disproportionate impact upon ethnic minorities. This timely volume will be of great interest to those interested in the study of race and the social impacts of the COVID-19 pandemic in the United States.

Weaving together political, sociological, psychological, and epidemiological analyses, Social and Political Representations of the COVID-19 Crisis provides revealing insights into the transformations wrought by the pandemic and the social divisions it has exposed. Accounting for the realities of the pandemic across the globe, with a strong focus on experiences in the Global South, this book challenges readers to question their beliefs about the societies they live in and how these societies should respond to collective catastrophes. Originally published in Spanish, this English edition is thoroughly revised and updated. Social and Political Representations of the COVID-19 Crisis analyzes the varied strategies attempted in different parts of the world to deal with the pandemic, including elimination, mitigation, flattening the curve, and herd immunity, and the ramifications of these approaches. It argues that the different strategies are guided by social representations that can be analyzed on epistemological, emotional, and ethical-moral levels. Drawing upon a wide range of thinkers, the book also investigates the key role of psychological defense mechanisms, including different ways of denying the seriousness of the pandemic and different paranoid responses to pain and frustration, such as scapegoating and conspiracy theories. This timely book analyzes the transformations in the social fabric brought about by the pandemic and the questions it poses for the future of our societies. It will therefore be of great interest to students and researchers in the humanities, social sciences, and public health, as well as the general reader.

Health Impact Assessment is a policy-support instrument and approach that seeks to assess the health impacts of projects, programmes and policies on population health. The ultimate goal of HIA is to systematically predict health impacts and subsequently inform the intersectoral decision- and policy-making processes of these impacts. Integrating Health Impact Assessment with the Policy Process examines how the process of integrating HIA with policy can take place. Introductory chapters outline the HIA process and provide a conceptual foundation for the book. Then, drawing from experiences of HIA practice and research globally, country specific experiences are presented to examine HIA's relationship with the policy process. Throughout the book checklists and learning points are provided to assist the readers' understanding of the concepts and examples discussed. This practical and conceptually-grounded guide represents a convergence of theory and practice from the disciplines of public health, environmental health and the social sciences, and will appeal to practitioners and professionals in these fields, as well as policy-makers, decision-makers, planners at regional and national government levels as well as academics, educators and students.

Insect-transmitted rickettsiales diseases are significant sources of morbidity and mortality all over the world. Their incidence has been increasing in recent years in large part due to climate change and the movement of animals carrying the insect vectors. Currently there are no effective vaccines against diseases caused by members of the order Rickettsiales. Rickettsiales diseases are often misdiagnosed; this book is intended to serve as a tool for their understanding and diagnosis. Rickettsiales covers the seven main genera: Anaplasma, Ehrlichia, Midichloria, Neorickettsia, Orientia, Rickettsia and Wolbachia. Discussion of each genus includes immunology and molecular biology of host-pathogen interactions, epidemiology and diagnosis, and vaccination strategies and therapies.

Comparing and Contrasting the Impact of the COVID-19 Pandemic in the European Union challenges the use of uncontextualised comparisons of COVID-19 cases and deaths in member states during the period when Europe was the epicentre of the pandemic. This timely study looks behind the headlines and the statistics to demonstrate the value for knowledge exchange and policy learning of comparisons that are founded on an in-depth understanding of key socio-demographic and public health indicators within their policy settings. The book adopts innovative, integrated, multi-disciplinary international perspectives to track and assess a fast-moving topical subject in an accessible format. It offers a template for analysing policy responses to the COVID-19 pandemic and for using evidence-based comparisons to inform and support policy development.

The National Centre for Infectious Diseases (NCID) is the result of many years in the planning, and it finally officially opened its doors in September 2019, just months before the entire world was tested by the COVID-19 pandemic. This book is the work of many people who represent an even larger pool of people from NCID, Singapore and the rest of the world in trying to understand and contain the SARS- CoV-2 virus. There are chapters on science, the public health response both locally and globally, as well as personal reflections from NCID and Tan Tock Seng Hospital staff and staff from other public healthcare institutions who were deployed to NCID which bring home the human impact of the pandemic. We are very grateful to all the authors for taking the time to put together their thoughtful chapters as well as the senior academics and public health leaders who have provided us with generous comments on the manuscript. We hope that the readers of the book will gain a better insight into the response to the virus from so many different perspectives. Although the pandemic has evolved far beyond the pages of this book globally, the lessons learned from the early days are still relevant. We hope that the chapters will be helpful as we review our experience of this pandemic and face the next emerging infectious disease in the years to come.This book provides a comprehensive look at many different aspects of response in Singapore to the pandemic in the crucial first several months, including clinical, laboratory, epidemiology, research, community engagement and the unprecedented challenge of outbreak involving migrant workers in dormitory settings. On a personal note, it has first-hand accounts of staff at the NCID who were at the forefront of battling COVID-19 in Singapore. It also gives a global perspective of the pandemic, together with insights into the unique Singapore experience of managing the pandemic. The Singapore response to the pandemic has been something which the global community has been very interested in and this book is the first to comprehensively describe that response from a number of different angles which will be useful to scientists, clinicians, public health professionals and policy makers.
