    Preparing for biological threats: Addressing the needs of pregnant women.
    Birth Defects Res 2017 Mar;109(5):391-398
    Centers for Disease Control and Prevention, Atlanta, Georgia.
    Intentional release of infectious agents and biological weapons to cause illness and death has the potential to greatly impact pregnant women and their fetuses. We review what is known about the maternal and fetal effects of seven biological threats: Bacillus anthracis (anthrax); variola virus (smallpox); Clostridium botulinum toxin (botulism); Burkholderia mallei (glanders) and Burkholderia pseudomallei (melioidosis); Yersinia pestis (plague); Francisella tularensis (tularemia); and Rickettsia prowazekii (typhus). Evaluating the potential maternal, fetal, and infant consequences of an intentional release of an infectious agent requires an assessment of several key issues: (1) are pregnant women more susceptible to infection or illness compared to the general population?; (2) are pregnant women at increased risk for severe illness, morbidity, and mortality compared to the general population?; (3) does infection or illness during pregnancy place women, the fetus, or the infant at increased risk for adverse outcomes and how does this affect clinical management?; and (4) are the medical countermeasures recommended for the general population safe and effective during pregnancy? These issues help frame national guidance for the care of pregnant women during an intentional release of a biological threat. Read More

    J Neuroimmunol 2017 May 21;306:31-39. Epub 2017 Feb 21.
    Department of Biochemistry and Molecular Biology, Baylor College of Medicine, Houston, TX 77030, USA; Department of Pathology and Immunology, Baylor College of Medicine, Houston, TX 77030, USA. Electronic address:
    We have conducted a 26-month-long comparative study involving young patients (2-6years old) with a clinical diagnosis of spastic equinus secondary to cerebral palsy who have been treated with BoNT/A (BOTOX®, Allergan) tri-annually or annually. Serum samples were obtained to determine the presence or absence of blocking antibodies (Abs) by a mouse protection assay (MPA) and levels of anti-BoNT/A Abs by radioimmune assay (RIA). HLA DQ alleles were typed using blood samples to determine the possible association of certain HLA type(s) with the disease or with the Ab status. Read More
