This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
The fact that tobacco ingestion can affect how people feel and think has been known for millennia, placing the plant among those used spiritually, honori?cally, and habitually (Corti 1931; Wilbert 1987). However, the conclusion that nicotine - counted for many of these psychopharmacological effects did not emerge until the nineteenth century (Langley 1905). This was elegantly described by Lewin in 1931 as follows: “The decisive factor in the effects of tobacco, desired or undesired, is nicotine. . . ”(Lewin 1998). The use of nicotine as a pharmacological probe to und- stand physiological functioning at the dawn of the twentieth century was a landmark in the birth of modern neuropharmacology (Limbird 2004; Halliwell 2007), and led the pioneering researcher John Langley to conclude that there must exist some “- ceptive substance” to explain the diverse actions of various substances, including nicotine, when applied to muscle tissue (Langley 1905). Research on tobacco and nicotine progressed throughout the twentieth century, but much of this was from a general pharmacological and toxicological rather than a psychopharmacological perspective (Larson et al. 1961). There was some attention to the effects related to addiction, such as euphoria (Johnston 1941), tolerance (Lewin 1931), and withdrawal (Finnegan et al. 1945), but outside of research supported by the tobacco industry, addiction and psychopharmacology were not major foci for research (Slade et al. 1995; Hurt and Robertson 1998; Henning?eld et al. 2006; Henning?eld and Hartel 1999; Larson et al. 1961).
A respected resource for decades, the Guide for the Care and Use of Laboratory Animals has been updated by a committee of experts, taking into consideration input from the scientific and laboratory animal communities and the public at large. The Guide incorporates new scientific information on common laboratory animals, including aquatic species, and includes extensive references. It is organized around major components of animal use: Key concepts of animal care and use. The Guide sets the framework for the humane care and use of laboratory animals. Animal care and use program. The Guide discusses the concept of a broad Program of Animal Care and Use, including roles and responsibilities of the Institutional Official, Attending Veterinarian and the Institutional Animal Care and Use Committee. Animal environment, husbandry, and management. A chapter on this topic is now divided into sections on terrestrial and aquatic animals and provides recommendations for housing and environment, husbandry, behavioral and population management, and more. Veterinary care. The Guide discusses veterinary care and the responsibilities of the Attending Veterinarian. It includes recommendations on animal procurement and transportation, preventive medicine (including animal biosecurity), and clinical care and management. The Guide addresses distress and pain recognition and relief, and issues surrounding euthanasia. Physical plant. The Guide identifies design issues, providing construction guidelines for functional areas; considerations such as drainage, vibration and noise control, and environmental monitoring; and specialized facilities for animal housing and research needs. The Guide for the Care and Use of Laboratory Animals provides a framework for the judgments required in the management of animal facilities. This updated and expanded resource of proven value will be important to scientists and researchers, veterinarians, animal care personnel, facilities managers, institutional administrators, policy makers involved in research issues, and animal welfare advocates.
Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
As occupational therapy celebrates its centennial in 2017, attention returns to the profession's founding belief in the value of therapeutic occupations as a way to remediate illness and maintain health. The founders emphasized the importance of establishing a therapeutic relationship with each client and designing an intervention plan based on the knowledge about a client's context and environment, values, goals, and needs. Using today's lexicon, the profession's founders proposed a vision for the profession that was occupation based, client centered, and evidence based--the vision articulated in the third edition of the Occupational Therapy Practice Framework: Domain and Process. The Framework is a must-have official document from the American Occupational Therapy Association. Intended for occupational therapy practitioners and students, other health care professionals, educators, researchers, payers, and consumers, the Framework summarizes the interrelated constructs that describe occupational therapy practice. In addition to the creation of a new preface to set the tone for the work, this new edition includes the following highlights: a redefinition of the overarching statement describing occupational therapy's domain; a new definition of clients that includes persons, groups, and populations; further delineation of the profession's relationship to organizations; inclusion of activity demands as part of the process; and even more up-to-date analysis and guidance for today's occupational therapy practitioners. Achieving health, well-being, and participation in life through engagement in occupation is the overarching statement that describes the domain and process of occupational therapy in the fullest sense. The Framework can provide the structure and guidance that practitioners can use to meet this important goal.
An ethnography of magic-religious, medicinal and recreational tobacco use among nearly 300 native South American societies. Wilbert found that South American Indians use tobacco in many ways and that a close functional relation exists between tobacco and shamanism.
