Human Longevity, Individual Life Duration, and the Growth of the Oldest-Old Population


Book Description

Old-age survival has considerably improved in the second half of the twentieth century. Why has such a substantial extension of human lifespan occurred? How long can we live? In this book, these fundamental questions are explored by experts from diverse fields. They report on recent cutting-edge studies about essential issues of human longevity and social factors of long survival in old age.




Explaining Divergent Levels of Longevity in High-Income Countries


Book Description

During the last 25 years, life expectancy at age 50 in the United States has been rising, but at a slower pace than in many other high-income countries, such as Japan and Australia. This difference is particularly notable given that the United States spends more on health care than any other nation. Concerned about this divergence, the National Institute on Aging asked the National Research Council to examine evidence on its possible causes. According to Explaining Divergent Levels of Longevity in High-Income Countries, the nation's history of heavy smoking is a major reason why lifespans in the United States fall short of those in many other high-income nations. Evidence suggests that current obesity levels play a substantial part as well. The book reports that lack of universal access to health care in the U.S. also has increased mortality and reduced life expectancy, though this is a less significant factor for those over age 65 because of Medicare access. For the main causes of death at older ages-cancer and cardiovascular disease-available indicators do not suggest that the U.S. health care system is failing to prevent deaths that would be averted elsewhere. In fact, cancer detection and survival appear to be better in the U.S. than in most other high-income nations, and survival rates following a heart attack also are favorable. Explaining Divergent Levels of Longevity in High-Income Countries identifies many gaps in research. For instance, while lung cancer deaths are a reliable marker of the damage from smoking, no clear-cut marker exists for obesity, physical inactivity, social integration, or other risks considered in this book. Moreover, evaluation of these risk factors is based on observational studies, which-unlike randomized controlled trials-are subject to many biases.




Between Zeus and the Salmon


Book Description

Demographers and public health specialists have been surprised by the rapid increases in life expectancy, especially at the oldest ages, that have occurred since the early 1960s. Some scientists are calling into question the idea of a fixed upper limit for the human life span. There is new evidence about the genetic bases for both humans and other species. There are also new theories and models of the role of mutations accumulating over the life span and the possible evolutionary advantages of survival after the reproductive years. This volume deals with such diverse topics as the role of the elderly in other species and among human societies past and present, the contribution of evolutionary theory to our understanding of human longevity and intergenerational transfers, mathematical models for survival, and the potential for collecting genetic material in household surveys. It will be particularly valuable for promoting communication between the social and life sciences.




Aging


Book Description

"Aging affects us all and is characterized not only by increasing frailty but by increased susceptibility to conditions such as Alzheimer's, cardiovascular disease, and cancer. We are gaining an increasing understanding of the molecular mechanisms underlying aging, however, and uncovering clues to how life may be prolonged. This book examines the biological basis of aging and research into strategies that may extend lifespan"--




Epigenetics of Aging


Book Description

Recent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research. The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins. Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer’s disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.




Advances in Geroscience


Book Description

This book provides the first comprehensive overview of a new scientific discipline termed Geroscience. Geroscience examines the molecular and cellular mechanisms that might explain why aging is the main risk factor for most chronic diseases affecting the elderly population. Over the past few decades, researchers have made impressive progress in understanding the genetics, biology and physiology of aging. This book presents vital research that can help readers to better understand how aging is a critical malleable risk factor in most chronic diseases, which, in turn, could lead to interventions that can help increase a healthy lifespan, or ‘healthspan.’ The book begins with an analysis of the Geroscience hypothesis, as well as the epidemiological underpinnings that define aging as a candidate main risk factor for most chronic diseases. Next, each chapter focuses on one particular disease, or group of diseases, with an emphasis on how basic molecular and cellular biology might explain why aging is a major risk factor for it. Coverage in the book includes: cancer, cardiovascular disease, dementias, stroke, Parkinson's and Alzheimer’s diseases, osteoporosis, arthritis, diabetes asthma, emphysema, kidney disease, vision impairment, and AIDS/HIV. It finishes with a chapter on pain in the elderly and an overview of future steps needed to bring the newly acquired knowledge into the clinic and the public at large.




Biomarkers of Human Longevity


Book Description

There is perhaps no other single technology or industry subsector, with the exception of AI, that has more potential to accelerate the realization of real-world impacts in Longevity across the full scope of its sectors and domains - industry, policy, investment, entrepreneurship, policy, and governance - than Biomarkers of Human Longevity. Given the unique confluence of Biomarkers of Human Longevity's disruptive impact and accelerative potential, on the one hand, and the high degree of disharmonization in terms of what they are and how they could and should be used, on the other hand, it is clear to me that there is a pressing unmet need for the production of a dedicated book that takes Biomarkers of Longevity as its central concern and major fulcrum, identifying the true potential that this technology has to increase individual and national Health-Adjusted Life Expectancy (HALE) and Quality-Adjusted Life Expectancy (QALY), optimize strategic decision-making for start-ups and corporations, de-risk investment, provide for the first time a tangible framework for company valuation, due diligence based on human validation, enable reliable forecasting clinical outcomes, serve as an effective platform for safe self-experimentation and personalized therapeutic fine-tuning, and pave the way for a much more tangible, stable and scalable Global Longevity Industry, where Longevity's socially-inclusive humanitarian impact is maximized and its potential ethical and socioeconomic concerns are neutralized. Deep Knowledge Group and its Longevity-focused subsidiaries and affiliates, including its analytical subsidiary Aging Analytics Agency, its specialized investment arm Longevity.Capital, its portfolio companies Longevity Banking Card and Longevity Financial Advisors and the international non-profit consortium Longevity.International, have prioritized the pressing need and the extreme potential of Biomarkers of Human Longevity (and integrated them in various ways into its overall scope of activities and strategic agenda) for several years now, and are expertly positioned to provide a tangible understanding of the major challenges and opportunities to be faced within this domain, and how they can be applied by individuals, institutions and even entire governments in order to achieve their maximum benefits while neutralizing potential pitfalls and issues.




The Epidemiology of Aging


Book Description

The average age of the world’s population is increasing at an unprecedented rate and this increase is changing the world. This “Silver tsunami” emphasizes the need to provide advanced training in epidemiology and increase the cadre of experts in the study of aging. This book is designed to summarize unique methodological issues relevant to the study of aging, biomarkers of aging and the biology/physiology of aging and in-depth discussions of the etiology and epidemiology of common geriatric syndromes and diseases. Contributing authors in the book represent many disciplines, not only epidemiology and clinical geriatrics, but also demography, health services, research, cardiovascular disease, diabetes, psychiatry, neurology, social services, musculoskeletal diseases and cancer. The aim of the book is to provide a broad multidisciplinary background for any student/researcher interested in aging. The material in the book is organized and comprehensive. It represents the most up-to-date information on the scientific issues in aging research written by academics who specialize in research and training in the broad field of aging. The structure and organization of the book reflects our course series in the Epidemiology of Aging starting with the broad issues of demography and methodology, and then addressing specific health conditions and geriatric conditions common to older persons.




Business Engagement in Building Healthy Communities


Book Description

Business Engagement in Building Healthy Communities is the summary of a workshop convened by the Institute of Medicine's Roundtable on Population Health Improvement in July 2014 to consider the role of business in improving population health beyond the usual worksite wellness and health promotion activities. The workshop followed previous roundtable discussions on the importance of applying a health lens to decision making in non-health sectors and the need for cross-sector collaborations to advance population health. Invited speakers included representatives from several businesses that have taken action to improve the health of their communities and representatives of business coalitions on health. The workshop was designed to discuss why engaging in population health improvement is good for business; explore how businesses can be effective key leaders in improving the health of communities; and discuss ways in which businesses can engage in population health improvement.
