Book Description

In the clinical microbiology laboratory, blood is a critical diagnostic sample that, in the majority of cases is sterile (or is it?). However, when microbes gain access to and multiply in the bloodstream, it can result in life-threatening illness including sepsis. Mortality rates from bloodstream infection and sepsis range from 25% to 80%, killing millions of people annually. Blood cultures are a vital technology used in the microbiology laboratory to isolate and identify microbes and predict their response to antimicrobial therapy. The Dark Art of Blood Cultures, edited by Wm. Michael Dunne, Jr., and Carey-Ann D. Burnham, surveys the entire field of blood culture technology, providing valuable information about every phase of the process, from drawing samples to culture methods to processing positive cultures. The Dark Art of Blood Cultures is organized around several major topics. History of blood culture methods. Details the timeline of blood culture methods from manual through automated and describes the technological development of the leading automated blood culture systems (Bactec, BacT/Alert, and VersaTREK). Manual and automated blood culture methods. Critiques manual and automated methods for setting up blood cultures for adult and pediatric patients. Detection of pathogens directly from blood specimens. Describes currently available CE marked and FDA-cleared commercial tests using both phenotypic and genotypic markers, including their strengths and limitations. The workflow of culturing blood. Includes best practices from specimen collection to culture system verification, processing positive cultures for microbe identification and antibiotic susceptibility determination, along with the epidemiology of positive blood cultures and the value of postmortem blood cultures. Microorganisms in the blood. Examines the concept of a blood microbiome in healthy and diseased individuals. The Dark Art of Blood Cultures is a resource that clinicians, laboratorians, lab directors, and hospital administrators will find engaging and extremely useful.

Book Description

Over the past decade, immigration and globalization have significantly altered Europe’s cultural and ethnic landscape, foregrounding questions of national belonging. In Blood and Culture, Cynthia Miller-Idriss provides a rich ethnographic analysis of how patterns of national identity are constructed and transformed across generations. Drawing on research she conducted at German vocational schools between 1999 and 2004, Miller-Idriss examines how the working-class students and their middle-class, college-educated teachers wrestle with their different views about citizenship and national pride. The cultural and demographic trends in Germany are broadly indicative of those underway throughout Europe, yet the country’s role in the Second World War and the Holocaust makes national identity, and particularly national pride, a difficult issue for Germans. Because the vocational-school teachers are mostly members of a generation that came of age in the 1960s and 1970s and hold their parents’ generation responsible for National Socialism, many see national pride as symptomatic of fascist thinking. Their students, on the other hand, want to take pride in being German. Miller-Idriss describes a new understanding of national belonging emerging among young Germans—one in which cultural assimilation takes precedence over blood or ethnic heritage. Moreover, she argues that teachers’ well-intentioned, state-sanctioned efforts to counter nationalist pride often create a backlash, making radical right-wing groups more appealing to their students. Miller-Idriss argues that the state’s efforts to shape national identity are always tempered and potentially transformed as each generation reacts to the official conception of what the nation “ought” to be.

Book Description

The emergence of symbolic culture is generally linked with the development of the hunger-gatherer adaptation based on a sexual division of labor. This original and ingenious book presents a new theory of how this symbolic domain originated. Integrating perspectives of evolutionary biography and social anthropology within a Marxist framework, Chris Knight rejects the common assumption that human culture was a modified extension of primate behavior and argues instead that it was the product of an immense social, sexual, and political revolution initiated by women. Culture became established, says Knight, when evolving human females began to assert collective control over their own sexuality, refusing sex to all males except those who came to them with provisions. Women usually timed their ban on sexual relations with their periods of infertility while they were menstruating, and to the extent that their solidarity drew women together, these periods tended to occur in synchrony. The result was that every month with the onset of menstruation, sexual relations were ruptured in a collective, ritualistic way as the prelude to each successful hunting expedition. This ritual act was the means through which women motivated men not only to hunt but also to concentrate energies on bringing back the meat. Knight shows how this hypothesis sheds light on the roots of such cultural traditions as totemic rituals, incest and menstrual taboos, blood-sacrifice, and hunters’ atonement rites. Providing detailed ethnographic documentation, he also explains how Native American, Australian Aboriginal, and other magico-religious myths can be read as derivatives of the same symbolic logic.

Book Description

Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.

Book Description

Phlebotomy uses large, hollow needles to remove blood specimens for lab testing or blood donation. Each step in the process carries risks - both for patients and health workers. Patients may be bruised. Health workers may receive needle-stick injuries. Both can become infected with bloodborne organisms such as hepatitis B, HIV, syphilis or malaria. Moreover, each step affects the quality of the specimen and the diagnosis. A contaminated specimen will produce a misdiagnosis. Clerical errors can prove fatal. The new WHO guidelines provide recommended steps for safe phlebotomy and reiterate accepted principles for drawing, collecting blood and transporting blood to laboratories/blood banks.
