Ten years after the results of the Cash and Counseling Demonstration and Evaluation were released, this book assesses the impact of this study, which developed individualized plans for helping people with disabilities to stay independent in the community. The study was the first wide-scale test of people with disabilities managing their own budgets and results from the random-controlled trial demonstrated significant positive outcomes, encouraging the US federal and state governments to provide this option as part of their community-based care programs. This volume looks at what people with disabilities and their caregivers are saying about this option ten years removed from the study, and what the latest research shows in terms of what it will take to improve this approach, making the option available for all people with disabilities. The contributions also discuss what needs remain unmet even when people can manage their own budgets, and present participants' and their family caregivers' views on what support broker activities really help (or hurt). Finally, the book summarizes the results of a project involving the Council of Social Work Education and nine schools of social work to develop modules to train future social workers on person-centred planning and participant direction. Of interest to those researchers studying social care with a focus on disabilities, this book would also be of use to those training social workers and support staff. The chapters in this book were originally published in the Journal of Gerontological Social Work and Home Health Care Services Quarterly.

The world continues to lose more than a million lives each year to the HIV epidemic, and nearly two million individuals were infected with HIV in 2017 alone. The new Sustainable Development Goals, adopted by countries of the United Nations in September 2015, include a commitment to end the AIDS epidemic by 2030. Considerable emphasis on prevention of new infections and treatment of those living with HIV will be needed to make this goal achievable. With nearly 37 million people now living with HIV, it is a communicable disease that behaves like a noncommunicable disease. Nutritional management is integral to comprehensive HIV care and treatment. Improved nutritional status and weight gain can increase recovery and strength of individuals living with HIV/AIDS, improve dietary diversity and caloric intake, and improve quality of life. This book highlights evidence-based research linking nutrition and HIV and identifies research gaps to inform the development of guidelines and policies for the United Nations' Sustainable Development Goals. A comprehensive approach that includes nutritional interventions is likely to maximize the benefit of antiretroviral therapy in preventing HIV disease progression and other adverse outcomes in HIV-infected men and women. Modification of nutritional status has been shown to enhance the quality of life of those suffering HIV/AIDS, both physically in terms of improved body mass index and immunological markers, and psychologically, by improving symptoms of depression. While the primary focus for those infected should remain on antiretroviral treatment and increasing its availability and coverage, improvement of nutritional status plays a complementary role in the management of HIV infection.

The authors review the principles of public health nutrition, examining nutritional epidemiology and programs that deal with health disparities, weight control challenges, and the needs of special populations. The text addresses the practice of public health nutrition through tools for conducting a food and nutrition assessment of a community, designing and carrying out a social marketing campaign, and developing large and small grant proposals. Nutrition in Public Health provides an integrated view of nutrition needs and the policies and political mechanisms that affect the delivery of quality food and nutrition services. It gives students a thorough understanding of the federal government's role in determining nutrition policy and influencing practice.

In 1981, David Jenkins, Thomas Wolever, and colleagues introduced the concept of the glycemic index (GI) to differentiate carbohydrates based on the rate of blood glucose rise following their consumption. Although GI was first used in diet therapy for diabetes, research evidence has accumulated since then to thousands of publications from all over the world with applications for prevention and/or management of many diseases, as well as effects on physiological states and exercise. The Glycemic Index: Applications in Practice has gathered together, in an unbiased and critical way, all the evidence and research on GI, including diabetes, cardiovascular disease, cancer, obesity, polycystic ovary syndrome, pregnancy outcomes, sports performance, eye health, and cognitive functioning. It provides a detailed explanation on how to correctly measure a food's GI, how the GI of food products can be altered, as well as the use and misuse of GI labelling around the globe. The contributors are either pioneers or experts in the area of GI from all around the globe, including Australia, Canada, Europe, and the United States. The book is a valuable source of information for healthcare professionals of various disciplines, nutritionists, dietitians, food scientists, medical doctors, sports scientists, psychologists, public health (nutrition) policy makers, and students in these fields, as well as an important addition to university libraries.

There are thousands of substances manufactured in the United States to which the public is routinely exposed and for which toxicity data are limited or absent. Some insist that uncertainty about the severity of potential harm justifies implementing precautionary regulations, while others claim that uncertainty justifies the absence of regulations until sufficient evidence confirms a strong probability of severe harm. In this book, Levente Szentkiralyi overcomes this impasse in his defense of precautionary environmental risk regulation by shifting the focus from how to manage uncertainty to what it is we owe each other morally. He argues that actions that create uncertain threats wrongfully gamble with the welfare of those who are exposed and neglect the reciprocity that our equal moral standing demands. If we take the moral equality and rights of others seriously, we have a duty to exercise due care to strive to prevent putting them in possible harm's way. The Ethics of Precaution will be of great interest to researchers, educators, advanced students, and practitioners working in the fields of environmental political theory, ethics of risk, and environmental policy.

Lactic acid bacteria (LAB) are a diverse group of bacteria that comprise low GC content Gram-positive cocci or rods that produces lactic acid as the major end product of the fermentation process. Bifidobacterium genera may also be considered as a part of the LAB group for possessing some similar phenotypical characteristics despite the higher GC content. The key feature of LAB metabolism is efficient carbohydrate fermentation. This contributes to the production of several microbial metabolites that result in the improvement of flavor and texture of fermented foods, in addition to its positive impact on the human health when LAB is administered as a probiotic. The book deals with advances made in the functionalities of LAB, such as their effect on vitamin D receptor expression, impact on neurodegenerative pathologies, production of B-vitamins for food bio-enrichment, production of bacteriocins to improve gut microbiota dysbiosis, production of metabolites from polyphenols and their effects on human health, effect on reducing the immunoreaction of food allergens, as biological system using time-temperature to improve food safety, and the use of probiotics in animal feed. The book also reviews the use of LAB and probiotic technologies to develop new functional foods and functional pharmaceuticals.

The US political system has come to depend upon money too much. The US health care industry spends the most on political lobbying among all the 13 industrial sectors in the US economy. The government regulatory agencies at both federal and state levels have been "captured" by the health industry interest groups meaning that the regulatory agencies respond to the interests of the industry but not those of citizens. This book employs a broad theoretical framework of crony capitalism to understand US health care system dysfunction. This framework has not been applied before in any serious manner to understand the shortcomings in the US health care system. Specifically, the book examines the role of seven key players using this framework - politicians/interest groups, pharmaceutical companies, private health insurers, hospitals/hospital networks, physicians, medical device manufacturers, and the American public. Crony capitalism is a destructive force and is rampant in US health care system, causing much waste, inefficiencies, and malaise in the system. Current efforts and initiatives, such as patient-centered medical homes and precision medicine, for improving/reforming the system are of mere academic interest and tantamount to taking aspirin to treat cancer. They do not even pretend to address the root cause of the problem, namely, crony capitalism. Offering prescriptions to fix the U.S. health care system based on a comprehensive diagnosis of the dysfunction, this book will be of interest to researchers, academics, policymakers, and students in the fields of health care management, public and non-profit management, health policy, administration, and economics, and political science.

From tuberculosis to bird flu and HIV to coronavirus, these infectious diseases share a common origin story: human interaction with animals. Otherwise known as zoonotic diseases for their passage from animals to humans, these pathogens - both pre-existing ones and those newly identified - emerge and re-emerge throughout history, sparking epidemics and pandemics that have resulted in millions of deaths around the world. How did these diseases come about? And what-if anything-can we do to stop them and their fatal march into our countries, our homes, and our bodies?

In How to Survive a Pandemic, Dr. Michael Greger, physician and internationally-recognized expert on public health issues, delves into the origins of some of the deadliest pathogens the world has ever seen. Tracing their evolution from the past until today, Dr. Greger spotlights emerging flu and coronaviruses as he examines where these pathogens originated, as well as the underlying conditions and significant human role that have exacerbated their lethal influence to large, and even global, levels.

As the world grapples with the devastating impact of the novel coronavirus 2019, Dr. Greger reveals not only what we can do to protect ourselves and our loved ones during a pandemic, but also what human society must rectify to reduce the likelihood of even worse catastrophes in the future.

Our brain is recognized by all specialists as the most complex entity created in nature. Regarding the extraordinary capacities of its functioning, still incompletely known, the control of the brain by our dietary lipids may seem very improbable to many people. Yet, research has shown that an imbalance in the intake of essential fatty acids is related to conditions as prevalent as depression, bipolar disorder and schizophrenia. Research on psychological disorders including attention deficit hyperactivity disorder, autism, aggressiveness and suicidal behavior are discussed in this text. Several neurodegenerative diseases, such as Alzheimer's, Parkinson's and multiple sclerosis are also explored. Several observations prove that not only are omega-3 fatty acids actively involved in maintaining the noble functions of our brain, but other lipids, including cholesterol, liposoluble vitamins (A, D and E) and some carotenoids play roles as well and are presented in this book. Dietary Lipids for Healthy Brain Function focuses on this important research for human health. This book brings readers, doctors, dietitians and nutritionists arguments that could improve brain development in young people, prevent many nervous diseases and slow down the age-related decline of higher brain functions. This book provides helpful information to improve health in the young as well in the old, using practical and personalized recommendations for preventing and treating nervous pathologies. Features: * Focuses on the importance of dietary lipids on the proper brain functioning. * Provides relevant references demonstrating the efficiency of dietary lipids to maintain a healthy brain. * Introduces lipid sources and describes their roles by lipid groups in behavior issues and various chronic nervous diseases.

This book explains how the U.S. federal system manages environmental health issues, with a unique focus on risk management and human health outcomes. Building on a generic approach for understanding human health risk, this book shows how federalism has evolved in response to environmental health problems, political and ideological variations in Washington D.C, as well as in-state and local governments. It examines laws, rules and regulations, showing how they stretch or fail to adapt to environmental health challenges. Emphasis is placed on human health and safety risk and how decisions have been influenced by environmental health information. The authors review different forms of federalism, and analyse how it has had to adapt to ever evolving environmental health hazards, such as global climate change, nanomaterials, nuclear waste, fresh air and water, as well as examining the impact of robotics and artificial intelligence on worker environmental health. They demonstrate the process for assessing hazard information and the process for federalism risk management, and subsequently arguing that human health and safety should receive greater attention. This book will be essential reading for students and scholars working on environmental health and environmental policy, particularly from a public health, and risk management viewpoint, in addition to practitioners and policymakers involved in environmental management and public policy.

Magnesium is an essential mineral required by humans, playing an important role in multiple biochemical processes as well as preventing and managing several diseases and disorders. Deficiencies of magnesium can lead to a wide range of medical conditions, including cardiovascular disease, diabetes, and hypertension. With myocardial infarction and stroke being the first and fifth cause of mortality in the United States, the pharmaceutical industry has been trying to produce therapies that reduce co-morbidity and mortality. Recent observational studies of magnesium have added to the list of potential therapeutic modalities that have been proven useful in reducing hypertension, stroke sequalae, metabolic syndrome/dyslipidemia, and inflammatory diseases. Magnesium therapeutic modalities also have impacts in the fields of neurology, the elderly, and in obstetrics. Magnesium: Applications in Clinical Medicine explores the many uses of magnesium and its applications in clinical medicine. Features: Presents information on the impacts magnesium has on various aspects of health conditions and disease prevention. Describes magnesium usage in treating and managing several conditions including dyslipidemia, migraine, metabolic syndrome, and high blood pressure. Discusses magnesium therapy in stroke and magnesium deficiency in attention deficit hyperactivity disorder. Promotes knowledge of overall health and wellness that can be applied in any specialty of medicine. This book encompasses various uses of magnesium in a clinical setting ranging from its role in maintaining homeostasis, to its uses in the fields of dermatology, cardiology, neurology, and in obstetrics. Written by contributors who are experts in their fields, it is a comprehensive collaboration of this ubiquitous dietary supplement's applications in clinical medicine.

Affecting more than 800 million people, food insecurity is a global problem that runs deeper than hunger and undernutrition. In addition to the obvious impact on physical well-being, food insecurity can result in risky coping strategies, increased expenditures on medical costs or transportation, and mental health issues. A review of the concepts and impacts of food insecurity through the lens of public health, Food Insecurity and Public Health details the complex issue of food insecurity and explores its reach beyond economics and agronomics. The book guides you through the fundamentals, beginning with theory, and the challenges in measuring it, and moving on to the impact of food insecurity on health. The book details the implications of food insecurity on public health practice, including epidemiology and outcomes of diseases such as HIV, TB, and non-communicable diseases, and the specific impact on women's health. It closes with case studies from the Navajo Nation, Kenya, and Southern Africa, offering the opportunity to learn from real-life successes and challenges. Each chapter also considers programs or interventions that have been used to attempt to address the issue, including a discussion of the US federal food stamps program. In truth, however, there continues to be a dearth of data on the ways in which programs can effectively address the problem of food insecurity at the household, community, or district level in either the short or long term-beyond, of course, the elimination of poverty, which is no doubt a root cause of the problem. The book gives you context for considering the links between food insecurity and health, and a framework for seeking integrated solutions to both problems.

Sharing the care of children in families is increasingly becoming the norm in modern-day society as more mothers enter paid work and government campaigns endeavour to increase the number of men working in childcare. However, running alongside debates of gender imbalance in childcare, there has also been mounting anxiety from the media and public about the risks of child abuse, often perceived as being mostly perpetrated by men and calling for firmer regulation of men's involvement with children. This book asks whether men's care for children, both as fathers and practitioners, actually differs at all from the care provided by mothers and female carers? In what ways do men and concepts of masculinity need to change if they are to play a greater role in the care of children or are such societal perceptions based on outdated gender stereotypes? Bringing together cutting-edge theory, up-to-date research and current practice, this book analyses the role of both fathers and male professionals working with children and highlights the implications of this for future policy and practice. It also examines dominant notions of masculinity and representations of male carers in the media and popular culture, asking how our societal expectations may need to evolve if men are to play an equal role in the care of children as demanded by current policy and wider social developments.

Currently, most books on youth research available on the market focus on 'how to' conduct youth research or the research process itself. This edited collection proposes to take this process a step further and discuss the complexities of youth research from a practical and theoretical context. In total, five themes are examined - conceptualising young people, ethics and consent, the digital, voice, participation and unexpected tensions. In this book, authors from six countries explore the complexities of researching with young people across disciplines and national contexts. Offering a closeup examination of their own research experiences, the authors address the complexities of researching with young people beyond simple questions of protection from harm and coercion by problematising notions of 'resilience', 'participation', 'risk' and 'voice'. This edited collection takes the reader through an exploration of its key themes and, in doing so, presents a cast of candid and insightful accounts from youth researchers situated within the humanities and social sciences.

Lycopene is a potent antioxidant carotenoid found in fruits and vegetables; particularly high amounts exist in red tomatoes. It is not an essential nutrient for humans, but can be a potential therapeutic agent for preventing several human diseases. Since the publication of the previous book on lycopene, extensive advances have been made with respect to the role of lycopene and tomatoes in human health. Whereas the initial focus of research was on cancer, Lycopene and Tomatoes in Human Nutrition and Health represents the next major step in documenting advances in understanding the chemistry, bioavailability, metabolism; mechanisms of action of lycopene; and its role in preventing human diseases other than cancer as discussed in the various chapters of the book. The book includes chapters that discuss genetic polymorphisms; and lycopene's relationship to cardiovascular diseases, cardiometabolic diseases, bone health, and other health disorders including male infertility, skin diseases, respiratory disorders and neurodegenerative diseases. The book includes information addressing regulatory aspects of natural health products and, in particular lycopene, presenting industrial insights. The contents of the book are selected carefully to provide the readers with the most current information available on lycopene and tomato bioactives.

More attention is being given towards how we grow and cultivate food sources whilst being mindful about the environmental impact this may have - this book is timely, the medical community is now giving due importance to dietary content.

'Beautifully written, intimate and intellectually fascinating' Nathan Filer 'This book represents, genuinely, a moment of ground-breaking importance for how we think about nature, access and wellbeing in late capitalism' Dr Alice Tarbuck 'Impeccably researched . . . A call to us all to find a place within the simplicity and complexity of nature' Lara Maiklem, bestselling author of Mudlarking Everybody is talking about the healing properties of nature. Hospitals are being retrofitted with gardens, and forests reimagined as wellbeing centres. On the Shetland Islands, it is possible to walk into a doctor's surgery with anxiety or depression, and walk out with a prescription for nature. Where has this come from, and what does 'going to nature' mean? Where is it - at the end of a garden, beyond the tarmac fringes of a city, at the summit of a mountain? Drawing on history, science, literature and art, Samantha Walton shows that the nature cure has deep roots - but, as we face an unprecedented crisis of mental health, social injustice and environmental devastation, the search for it is more urgent now than ever. Everybody Needs Beauty engages seriously with the connection between nature and health, while scrutinising the harmful trends of a wellness industry that seeks to exploit our relationship with the natural world. In doing so, this book explores how the nature cure might lead us towards a more just and radical way of life: a real means of recovery, for people, society and nature.

Film and the Chinese Medical Humanities is the first book to reflect on the power of film in representing medical and health discourse in China in both the past and the present, as well as in shaping its future. Drawing on both feature and documentary films from mainland China, the chapters each engage with the field of medicine through the visual arts. They cover themes such as the history of doctors and their concepts of disease and therapies, understanding the patient experience of illness and death, and establishing empathy and compassion in medical practice, as well as the HIV/AIDs epidemic during the 1980s and 90s and changing attitudes towards disability. Inherently interdisciplinary in nature, the contributors therefore provide different perspectives from the fields of history, psychiatry, film studies, anthropology, linguistics, public health and occupational therapy, as they relate to China and people who identify as Chinese. Their combined approaches are united by a passion for improving the cross-cultural understanding of the body and ultimately healthcare itself. A key resource for educators in the Medical Humanities, this book will be useful to students and scholars of Chinese Studies and Film Studies as well as global health, medical anthropology and medical history.

Fraudulent, harmful, or at best useless pharmaceutical and therapeutic approaches developed outside science-based medicine have boomed in recent years, especially due to the commercialisation of cyberspace. The latter has played a fundamental role in the rise of false 'health experts', and in the creation of filter bubbles and echo chambers that have contributed to the formation of highly polarised debates on non-science-based health practices-online as well as offline. By adopting a multidisciplinary approach, this edited book brings together contributions of international academics and practitioners from criminology, digital sociology, health psychology, medicine, law, physics, and journalism, where they critically analyse different types of non-science-based health approaches. With this volume, we aim to reconcile different scientific understandings of these practices, synthesising a variety of empirical, theoretical and interpretative approaches, and exploring the challenges, implications and potential remedies to the spread of dangerous and misleading health information. This edited book will offer some food for thought not only to students and academics in the social sciences, health psychology and medicine among other disciplines, but also to medical practitioners, science journalists, debunkers, policy makers and the general public, as they might all benefit from a greater awareness and critical knowledge of the harms caused by non-scientific health practices.
