PSAB ACTIVITIES
LOCS Notice: Best Practices for
Health Care Professionals on the Use of Polymerase Chain Reaction (PCR) for
Diagnosing Pertussis
The following
Health Alert Network (HAN) message was distributed on February 16, 2011 to
health care providers to improve consistency and reliability of pertussis
diagnosis (whooping cough) by nucleic acid amplification technology. This HAN
message is being shared as a LOCS advisory with the laboratory community,
including state, county and local public health laboratories, for enhancing
situational awareness and to facilitate communication across the health care
spectrum. The complete notice
is available on the CDC web page: http://www.cdc.gov/pertussis/clinical/diagnostic-testing/diagnosis-pcr-bestpractices.html.
LRN Partners Meeting
Alice Weissfeld, the ASM LRN Partners alternate representative, attended the LRN Partners meeting in Atlanta in February. A major topic was bioterrorism and emerging infection laboratory readiness. At the request of the LRN Partners, a poll is being conducted among divc and clinmicronet listserve members to obtain information on current levels of sentinel lab training. Results from the poll will be used in part to determine sentinel laboratory training needs. An APHL and ASM co-sponsored webinar is planned in April for public health laboratories related to bioterrorism laboratory readiness issues and ASM will participate to answer questions about the sentinel laboratory protocols and training of lab personnel. There are several other collaborations planned with APHL, including co-sponsored sentinel laboratory training at regional meetings.
ASM Action Alert on Federal Funding for Science and Public Health Programs
On February 15, the ASM Public and
Scientific Affairs Board sent an action alert to the membership concerning
proposed cuts to the FY 2011 federal agency budgets for science and public
health programs. The alert was in response to the proposed cuts for science and
public health programs in the House of Representatives’ bill (HR 1) to provide
funding for the remainder of Fiscal Year 2011.
It is very important that members of Congress hear from their
constituents about the adverse impacts of reducing federal funding for research
and public health programs. The ASM action alert and information about the FY
2011 and FY 2012 budgets for research and public health programs is available
on the ASM Public Affairs web site
at http://www.asm.org/index.php/policy/radfy2012.html.

Editor in Chief: David H. Persing, Cepheid
ISBN: 978-1-55581-497-7
The second edition of Molecular Microbiology: Diagnostic Principles and Practice presents the latest molecular diagnostic techniques to support clinical care and basic and clinical research. The authors—all experienced researchers and diagnosticians—have conducted a comprehensive review and evaluation of this rapidly evolving field and provide the new material in an easy-to-read summary format. Moreover, the book offers a broad range of practical advice, such as determining the appropriate type and quantity of a specimen, releasing and concentrating the targets, and eliminating inhibitors. http://estore.asm.org/viewItemDetails.asp?ItemID=971
Kucers’ The Use of Antibiotics, Sixth Edition
Lead Editor: M. Lindsay Grayson, University of Melbourne, Heidelberg, Victoria, Australia
ISBN: 978-0-34092-767-0
Concentrating on the treatment of infectious diseases, the content in the Sixth Edition is divided into 4 sections: antibiotics, anti-fungal drugs, anti-parasitic drugs and anti-viral drugs; and is highly structured for ease of reference. Within each section each chapter is structured to cover susceptibility, formulations and dosing (adult and pediatric), pharmacokinetics and pharmacodynamics, toxicity and drug distribution. Detailed discussions regarding clinical uses are also incorporated—a feature unique to this title. More than doubled in length compared to the Fifth Edition, the new edition comprises 3,000 pages over two volumes in order to cover all new and existing therapies and emerging drugs not yet fully licensed. http://estore.asm.org/viewItemDetails.asp?ItemID=910
ASM Journal Articles of Interest
Researchers Model Fetal-To-Adult Hemoglobin Switching: Important Step Towards Cure For Blood Diseases
Researchers have engineered mice that model the switch from fetal to adult hemoglobin, an important step towards curing genetic blood diseases such as sickle cell anemia and beta-thalassemia. The research is published in the February 2011 issue of the Journal Molecular and Cellular Biology.
They also
produced for the first time a mouse that synthesizes a distinct fetal-stage
hemoglobin, which was necessary for modeling human hemoglobin disorders. These
diseases manifest as misshapen hemoglobin, causing anemia, which can be severe,
as well as other symptoms, which can range from minor to life-threatening. The
cure would lie in causing the body to revert to use of fetal hemoglobin.
(S.C. McConnell, Y. Huo, S. Liu, and T.M. Ryan, 2011. Human globin knock-in mice complete fetal-to-adult hemoglobin switching in postnatal development. Mol. Cell. Biol. 31:876-883.)
Host Genetics Plays Unexpected Role in Dance with Pathogen
A new study suggests that differences in the host’s genetics can make a big difference in susceptibility bacterial infection. In a study in the February 2011 Infection and Immunity, Virginia L. Miller of the University of North Carolina, Chapel Hill, and her collaborators show that the virulence of a strain of Yersinia pestis, notable for causing bubonic plague, varies drastically among mice strains with different genetic backgrounds. These findings carry major implications for vaccine development, says Miller.
A number of earlier reports dating back 20 years had suggested that removing this bacterium’s capsule--an envelope of a loose protein gel surrounding the bacterial cell—had no effect on its virulence. Then, Miller and her collaborators performed the same experiment, with opposite results.
(E.H. Weening, J.S. Cathelyn, G. Kaufman, M.B. Lawrenz, P. Price, W.E. Goldman, and V.L. Miller, 2011. The dependence of the Yersinia pestis Infect. Immun. 79: 644-652.) capsule on pathogenesis is influenced by the mouse background.

New Reports from IOM
In 2009, the H1N1 influenza pandemic brought to the forefront the many unknowns about the virulence, spread, and nature of the virus, as well as questions regarding personal protective equipment (PPE) for healthcare personnel. In this report, the IOM assesses the progress of PPE research and identifies future directions for PPE for healthcare personnel.
With the widespread use of highly active anti-retroviral treatment (HAART), HIV has become a chronic, rather than a fatal, disease. But for their treatment to succeed, patients require uninterrupted care from a health care provider and uninterrupted access to anti-HIV medications. The IOM identifies federal, state, and private health insurance policies that inhibit HIV-positive individuals from initiating or continuing their care.
Clinical Data as the Basic Staple for Health Learning - Workshop Summary
