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.

Jeremiah Barker practiced medicine in rural Maine up until his retirement in 1818. Throughout his practice of fifty years, he documented his constant efforts to keep up with and contribute to the medical literature in a changing medical landscape, as practice and authority shifted from historical to scientific methods. He performed experiments and autopsies, became interested in the new chemistry of Lavoisier, risked scorn in his use of alkaline remedies, studied epidemic fever and approaches to bloodletting, and struggled to understand epidemic fever, childbed fever, cancer, public health, consumption, mental illness, and the "dangers of spirituous liquors." Dr. Barker intended to publish his Diseases in the District of Maine 1772-1820 by subscription - advance pledges to purchase the published volume - but for reasons that remain uncertain, that never happened. For the first time, Barker's never before published work has been transcribed and presented in its entirety with extensive annotations, a five-chapter introduction to contextualize the work, and a glossary to make it accessible to 21st century general readers, genealogists, students, and historians. This engaging and insightful new publication allows modern readers to reimagine medicine as practiced by a rural physician in New England. We know much about how elite physicians practiced 200 years ago, but very little about the daily practice of an ordinary rural doctor, attending the ordinary rural patient. Barker's manuscript is written in a clear and engaging style, easily enjoyed by general readers as well as historians, with extensive footnotes and a glossary of terms. Barker himself intended his book to be "understood by those destitute of medical science."

Infectious diseases are the leading cause of death globally, particularly among children and young adults. The spread of new pathogens and the threat of antimicrobial resistance pose particular challenges in combating these diseases. Major Infectious Diseases identifies feasible, cost-effective packages of interventions and strategies across delivery platforms to prevent and treat HIV/AIDS, other sexually transmitted infections, tuberculosis, malaria, adult febrile illness, viral hepatitis, and neglected tropical diseases. The volume emphasizes the need to effectively address emerging antimicrobial resistance, strengthen health systems, and increase access to care. The attainable goals are to reduce incidence, develop innovative approaches, and optimize existing tools in resource-constrained settings.

During the late 18th and early 19th centuries, there was a tubercular 'moment' in which perceptions of the consumptive disease became inextricably tied to contemporary concepts of beauty, playing out in the clothing fashions of the day. With the ravages of the illness widely regarded as conferring beauty on the sufferer, it became commonplace to regard tuberculosis as a positive affliction, one to be emulated in both beauty practices and dress. While medical writers of the time believed that the fashionable way of life of many women actually rendered them susceptible to the disease, Carolyn A. Day investigates the deliberate and widespread flouting of admonitions against these fashion practices in the pursuit of beauty. Through an exploration of contemporary social trends and medical advice revealed in medical writing, literature and personal papers, Consumptive Chic uncovers the intimate relationship between fashionable women's clothing, and medical understandings of the illness. Illustrated with over 40 full color fashion plates, caricatures, medical images, and photographs of original garments, this is a compelling story of the intimate relationship between the body, beauty, and disease - and the rise of 'tubercular chic'.
