This textbook describes the basics of research in medical, clinical, and biomedical settings as well as the concepts and application of epidemiologic designs in research conduct. Design transcends statistical techniques, and no matter how sophisticated a statistical modeling, errors of design/sampling cannot be corrected. The authors of this textbook have presented a complex field in a very simplified and reader-friendly manner with the intent that such presentation will facilitate the understanding of design process and epidemiologic thinking in clinical and biomedical research. Covers these relevant topics in epidemiology: Case-Cohort Design Prospective Case-Control Quantitative Evidence Synthesis (QES) Instant Cohort Design & Case-Crossover Design Effect Modification & Interaction Epidemiologic Tree - Molecular Epidemiology & Health Disparities Epidemiologic Challenge - "Big Data," mHealth, Social Media 3 "Ts" - Team Science, Transdisciplinary Research, Translational Research Bias, Random error, Confounding Systems Science & Evidence Discovery Research is presented as an exercise around measurement, with measurement error inevitable in its conduct-hence the inherent uncertainties of all findings in clinical and biomedical research. Concise Epidemiologic Principles and Concepts covers research conceptualization, namely research objectives, questions, hypothesis, design, implementation, data collection, analysis, results, and interpretation. While the primary focus of epidemiology is to assess the relationship between exposure (risk or predisposing factor) and outcome (disease or health-related event), causal association is presented in a simplified manner, including the role of quantitative evidence synthesis (meta-analysis) in causal inference. Epidemiology has evolved over the past three decades resulting in several fields being developed. This text presents in brief the perspectives and future of epidemiology in the era of the molecular basis of medicine. With molecular epidemiology, we are better equipped with tools to identify molecular biologic indicators of risk as well as biologic alterations in the early stages of disease.

Biostatistics deals with making sense of data. While statistical inference is essential in our application of the research findings to clinical decision-making regarding the care of our patients, statistical inference without clinical relevance or importance can be very misleading and even meaningless. This textbook has attempted to deemphasize p value in the interpretation of clinical and biomedical data by stressing the importance of confidence intervals, which allow for the quantification of evidence. For example, a large study due to a large sample size that minimizes variability may show a statistically significant difference while in reality the difference is too insignificant to warrant any clinical relevance. Covers these relevant topics in biostatistics: Design Process, Sampling & Reality in Statistical Modeling Basics of Biostatistical Reasoning & Inference Central Tendency Theorem & Measures of Dispersion Most commonly used & abused parametric test - t test Most commonly used & abused non-parametric test - chi squared statistic Sample size and power estimations Logistic/Binomial Regression Models - Binary Outcomes Time-to-Event Data - Survival Analysis & Count Data - Poisson Regression ANOVA, ANCOVA - Mixed Effects Model (Fixed and Random), RANOVA, GEE Simple & Multiple Linear Regression Models Correlation Analysis (Pearson & Spearman Rank) Clinical & Statistical Significance - p value as a function of sample size Clinical and biomedical researchers often ignore an important aspect of evidence discovery from their funded or unfunded projects. Since the attempt is to illustrate some sets of relationships from the data set, researchers often do not exercise substantial amount of time in assessing the reliability and validity of the data to be utilized in the analysis. However, the expected inference or the conclusion to be drawn is based on the analysis of the un-assessed data. Reality in statistical modeling of biomedical and clinical research data remains the focus of scientific evidence discovery, and this book. This text is written to highlight the importance of appropriate design prior to analysis by placing emphasis on subject selection and probability sample and the randomization process when applicable prior to the selection of the analytic tool. In addition, this book stresses the importance of biologic and clinical significance in the interpretation of study findings. The basis for statistical inference, implying the quantification of random error is random sample, which had been perpetually addressed in this book. When studies are conducted without a random sample, except when disease registries/databases or consecutive subjects are utilized, as often encountered in clinical and biomedical research, it is meaningless to report the findings with p value.

This is the first comprehensive text to provide not only a detailed explanation of how the SARS-CoV2 (COVID-19) virus is spread within human populations, but also an epidemiological analysis and interpretation of viral pandemics to enable better measures for preventions and control. Providing an introduction to the physiology of both the human immune system and the SARS-CoV2 virus, specifically the virus’s replicative potential and our own vulnerability, the book offers an in-depth understanding of how the pandemic evolved. It also highlights the aberrant epigenomic mechanistic process in pathogenic microbe’s replication and survival, implying gene and environment interaction that affected different populations. Citing a range of environmental conditions, from structural and systemic racism to malnutrition and low-socioeconomic status, the book examines how these factors exacerbated existing health disparities, resulting in a disproportionate burden of morbidity and mortality on certain social groups. Also providing invaluable guidance on how future iterations of this pandemic may be better prevented and controlled, this will be a defining book for students, researchers and professionals within Public Health and Clinical Medicine to better understand the SARS-CoV2 (COVID-19) virus, and how to protect the most vulnerable social groups.

This applied clinical medicine and public health text introduces the fundamental concepts in epidemiological investigation and demonstrates how to integrate emerging research on epigenomics into practice. Epidemiology has a vital strategic role in facilitating and leading evidence discovery in all aspects of human health, with the intent of improving patient and public health through disease control and health promotion practices. Emphasizing what we now know about the transformation the human body and the ecosystem undergo as a result of social structure, environment, daily challenges, and mutation. The first part of this text explores the origin of epidemiology, its relationship with medicine and public health, and its role in assessing disease distribution as occurrence or frequency, risk factors, treatment and management. The main direction of this text explores the assessment of how the gene and environment interaction, termed epigenomic modulations as aberrant predispose to morbidity, prognosis, survival and mortality at individual as well as the specific population level. This text presents a novel approach mainly epigenomic modulations in the application epidemiologic investigation in disease incidence, morbidity, and mortality at specific population level for graduate education in public health and clinical sciences as well as medical education.

The past three decades have witnessed modern advances in statistical modeling and evidence discovery in biomedical, clinical, and population-based research. With these advances come the challenges in accurate model stipulation and application of models in scientific evidence discovery Applied Biostatistical Principles and Concepts provides practical knowledge using biological and biochemical specimen/samples in order to understand health and disease processes at cellular, clinical, and population levels. Concepts and techniques provided will help researchers design and conduct studies, then translate data from bench to clinics in attempt to improve the health of patients and populations. This book is suitable for both clinicians and health or biological sciences students. It presents the reality in statistical modelling of health research data in a concise manner that will address the issue of "big data" type I error tolerance and probability value, effect size and confidence interval for precision, effect measure modification and interaction as well as confounders, thus allowing for more valid inferences and yielding results that are more reliable, valid and accurate.
