Book Description
This book, written by leading international experts, provides a comprehensive, current examination of transport-mediated antimicrobial resistance. As a particularly powerful mechanism of multidrug resistance, an in-depth examination of efflux pumps is conducted with bacteria of major public health concern including Enterobacteriaceae, Acinetobacter, Neisseria, Pseudomonas, staphylococci, and mycobacteria. The content spans structural biochemistry and transport mechanisms of the major transporter families and considers individual drug efflux systems across various Gram-positive and Gram-negative species. Genomic analysis of efflux pump distribution and their contribution to clinically-relevant resistance are a major focus of the text. Moreover, interplay between drug efflux pumps and other key resistance mechanisms such as intrinsic drug impermeability, inactivation, and target alterations are discussed, as well as their molecular expression-based regulation and physiological functions beyond resistance, involving biofilms, stress response, and pathogenicity. Finally, strategies are addressed to target this drug resistance mechanism with novel antimicrobials or drug inhibitor adjuvants.

Book Description
Our ability to treat common bacterial infections with antibiotics goes back only 65 years. However, the authors of this report make it clear that sustaining a supply of effective and affordable antibiotics cannot be without changes to the incentives facing patients, physicians, hospitals, insurers, and pharmaceutical manufacturers. In fact, increasing resistance to these drugs is already exacting a terrible price. Every day in the United States, approximately 172 men, women, and children die from infections caused by antibiotic-resistant bacteria in hospitals alone. Beyond those deaths, antibiotic resistance is costing billions of dollars through prolonged hospital stays and the need for doctors to resort to ever more costly drugs to use as substitute treatments. Extending the Cure presents the problem of antibiotic resistance as a conflict between individual decision makers and their short-term interest and the interest of society as a whole, in both present and future: The effort that doctors make to please each patient by prescribing a drug when it might not be properly indicated, poor monitoring of discharged patients to ensure that they do not transmit drug-resistant pathogens to other persons, excesses in the marketing of new antibiotics, and the broad overuse of antibiotics all contribute to the development and spread of antibiotic-resistant bacteria. The book explores a range of policy options that would encourage patients, health care providers, and managed care organizations to serve as more responsible stewards of existing antibiotics as well as proposals that would give pharmaceutical firms greater incentives to develop new antibiotics and avoid overselling. If the problem continues unaddressed, antibiotic resistance has the potential to derail the health care system and return us to a world where people of all ages routinely die from simple infections. As a basis for future research and a spur to a critically important dialogue, Extending the Cure is a fundamental first step in addressing this public health crisis. The Extending the Cure project is funded in part by the Robert Wood Johnson Foundation through its Pioneer Portfolio.

Book Description
It is our wish that readers discover the importance of polymyxin structure in relation to the mechanisms of activity, resistance and toxicity. We emphasized that reliable analytic methods for polymyxins are critical when investigating their pharmacokinetics (PK) and pharmacodynamics (PD). The complicated dose definitions and different pharmacopoeial standards have already compromised the safe use of polymyxins in patients. Therefore, informed by the latest pharmacological information, scientifically-based dosing recommendations have been proposed for intravenous polymyxins. Considering the PK/PD limitations and potential development of resistance, polymyxin combinations are encouraged; however, the current literature has not shown definite microbiological benefits, possibly because most clinical studies to date overlooked key PK/PD principles. Nephrotoxicity is the major dose-limiting factor and it is imperative to elucidate the mechanisms and develop novel approaches to minimize polymyxin-associated toxicities. In addition, the anti-endotoxin effect of polymyxins supports their clinical use to treat Gram-negative sepsis. Fortunately, the discovery of new-generation polymyxins with wider therapeutic windows has benefited from the latest achievements in polymyxin research.

Book Description
The generation of tridimensional tissues, assembled from scaffolding materials populated with biologically functional cells, is the great challenge and hope of tissue bioengineering and regenerative medicine. The generation of biomaterials capable of harnessing the immune system has been particularly successful. This book provides a comprehensive view of how immune cells can be manipulated to suppresses inflammation, deliver vaccines, fight cancer cells, promote tissue regeneration or inhibit blood clotting and bacterial infections by functionally engineered biomaterials. However, long-lived polymers, such as those employed in orthopedic surgery or vascular stents, can often induce an immune reaction to their basic components. As a result, this book is also an important step towards coming to understand how to manipulate biomaterials to optimize their beneficial effects and downplay detrimental immune responses.

These guidelines provide recommendations that outline the critical aspects of infection prevention and control. The recommendations were developed using the best available evidence and consensus methods by the Infection Control Steering Committee. They have been prioritised as key areas to prevent and control infection in a healthcare facility. It is recognised that the level of risk may differ according to the different types of facility and therefore some recommendations should be justified by risk assessment. When implementing these recommendations all healthcare facilities need to consider the risk of transmission of infection and implement according to their specific setting and circumstances.

Book Description
Drug overdose, driven largely by overdose related to the use of opioids, is now the leading cause of unintentional injury death in the United States. The ongoing opioid crisis lies at the intersection of two public health challenges: reducing the burden of suffering from pain and containing the rising toll of the harms that can arise from the use of opioid medications. Chronic pain and opioid use disorder both represent complex human conditions affecting millions of Americans and causing untold disability and loss of function. In the context of the growing opioid problem, the U.S. Food and Drug Administration (FDA) launched an Opioids Action Plan in early 2016. As part of this plan, the FDA asked the National Academies of Sciences, Engineering, and Medicine to convene a committee to update the state of the science on pain research, care, and education and to identify actions the FDA and others can take to respond to the opioid epidemic, with a particular focus on informing FDA's development of a formal method for incorporating individual and societal considerations into its risk-benefit framework for opioid approval and monitoring.

Book Description
The National Strategy for Combating Antibiotic Resistant Bacteria, published in 2014, sets out a plan for government work to mitigate the emergence and spread of resistant bacteria. Direction on the implementation of this strategy is provided in five-year national action plans, the first covering 2015 to 2020, and the second covering 2020 to 2025. Combating Antimicrobial Resistance and Protecting the Miracle of Modern Medicine evaluates progress made against the national strategy. This report discusses ways to improve detection of resistant infections and estimate the risk to human health from environmental sources of resistance. In addition, the report considers the effect of agricultural practices on human and animal health and animal welfare and ways these practices could be improved, and advises on key drugs and diseases for which animal-specific test breakpoints are needed.
