Use Of Urine Antigen Testing For Blastomyces In An Integrated Health System, Dennis J. Baumgardner
Use Of Urine Antigen Testing For Blastomyces In An Integrated Health System, Dennis J. Baumgardner
Dennis J. Baumgardner, MD
Purpose: Blastomycosis, an endemic fungal infection, mimics many other diseases. We explored the use of Blastomyces urine antigen (BuAg), reportedly the most sensitive noninvasive test, in clinical practice and compared it to other noninvasive tests.
Methods: A total of 836 BuAg tests performed on unique patients (first test only) at one large integrated health system from June 2013 to May 2016 were retrospectively reviewed to examine test characteristics and demographic features. Of these, 100 cases from 2015, a year containing a large local blastomycosis outbreak, were randomly selected for detailed analysis.
Results: Demographics for the BuAg-tested population: mean age 54.9 …

Geographic Distribution Of Infant Death During Birth Hospitalization And Maternal Group B Streptococcus Colonization: Eastern Wisconsin, Jessica J.F. Kram, Dennis J. Baumgardner, Kiley A. Bernhard, Melissa A. Lemke
Dennis J. Baumgardner, MD
Background: Neonatal death rate in the United States is 4/1,000 live births; infant death rate is 6/1,000. Group B Streptococcus (GBS) may be transmitted from a colonized mother (rates vary from 15% to 35%) to the newborn during a vaginal delivery, and may contribute to neonatal death.
Purpose: To explore the geographic distribution and associated risk factors for maternal GBS colonization and infant death prior to discharge in eastern Wisconsin births.
Methods: Retrospective study of institutional data from PeriData.net, a comprehensive birth registry, utilizing data from 2007 through 2013 at all Aurora medical centers. Categorical variables were analyzed with chi-square …

OBJECTIVE: To estimate the incidence of invasive pneumococcal disease and pneumonia, distribution of pneumococcal serotypes, and antibiotic susceptibility in children aged 28 days to <60 months. DESIGN: Hospital-based surveillance. SETTING: South Bangalore, India. PARTICIPANTS: 9950 children aged 28 days to <60 months with clinical suspicion of invasive pneumococcal disease or pneumonia. RESULTS: The estimated at-risk population included 224,966 children <5 years of age. Forty cases of invasive pneumococcal disease were identified. Estimated invasive pneumococcal disease incidence was 17.8/100,000 with incidence being highest among children aged 6 months to <12 months (49.9/100,000). Clinical pneumonia syndrome was the most frequent diagnosis (12.5/100,000). Pneumococcal serotypes included: 6A (n=6, 16.7%); 14 (n=5, 13.9%); 5 (n=4, 11.1%); 6B (n=4, 11.1%); 1, 18C, and 19A (n=3 each, 8.3%); 9V (n=2, 5.6%); and 3, 4, 10C, 18A, 18F, and 19F (n=1 each, 2.8%). Serotypes 6A, 14, 6B, 1, 18C, 19A, 9V, 4, 10C, and 18A showed antibiotic resistance. Clinical pneumonia incidence was 2109/100,000, with incidence being highest among children aged 28 days to <6 months (5033/100,000). Chest radiograph-confirmed pneumonia incidence was 1114/100,000, with incidence being highest among children aged 28 days to <6 months (2413/100,000). CONCLUSIONS: Invasive pneumococcal disease and pneumonia were found to be common causes of morbidity in young children living in South Bangalore, India.
Clinical Evaluation Of A Loop-Mediated Isothermal Amplification (Lamp) Assay For Rapid Detection Of Neisseria Meningitidis In Cerebrospinal Fluid, Paul E. Kilgore
Clinical Evaluation Of A Loop-Mediated Isothermal Amplification (Lamp) Assay For Rapid Detection Of Neisseria Meningitidis In Cerebrospinal Fluid, Paul E. Kilgore
Paul E. Kilgore
BACKGROUND: Neisseria meningitidis (Nm) is a leading causative agent of bacterial meningitis in humans. Traditionally, meningococcal meningitis has been diagnosed by bacterial culture. However, isolation of bacteria from patients' cerebrospinal fluid (CSF) is time consuming and sometimes yields negative results. Recently, polymerase chain reaction (PCR)-based diagnostic methods of detecting Nm have been considered the gold standard because of their superior sensitivity and specificity compared with culture. In this study, we developed a loop-mediated isothermal amplification (LAMP) method and evaluated its ability to detect Nm in cerebrospinal fluid (CSF). METHODOLOGY/PRINCIPAL FINDINGS: We developed a meningococcal LAMP assay (Nm LAMP) that targets …

Enterohemorrhagic Escherichia coli (EHEC) is an extracellular pathogen that causes hemorrhagic colitis and hemolytic uremic syndrome. The proinflammatory cytokine, interleukin-1beta, has been linked to hemolytic uremic syndrome. Here we identify the nucleotide-binding domain and leucine rich repeat containing family, pyrin domain containing 3 (NLRP3) inflammasome as an essential mediator of EHEC-induced IL-1beta. Whereas EHEC-specific virulence factors were dispensable for NLRP3 activation, bacterial nucleic acids such as RNA:DNA hybrids and RNA gained cytosolic access and mediated inflammasome-dependent responses. Consistent with a direct role for RNA:DNA hybrids in inflammasome activation, delivery of synthetic EHEC RNA:DNA hybrids into the cytosol triggered NLRP3-dependent responses, …

Cyclic paroxysm and high fever are hallmarks of malaria and are associated with high levels of pyrogenic cytokines, including IL-1beta. In this report, we describe a signature for the expression of inflammasome-related genes and caspase-1 activation in malaria. Indeed, when we infected mice, Plasmodium infection was sufficient to promote MyD88-mediated caspase-1 activation, dependent on IFN-gamma-priming and the expression of inflammasome components ASC, P2X7R, NLRP3 and/or NLRP12. Pro-IL-1beta expression required a second stimulation with LPS and was also dependent on IFN-gamma-priming and functional TNFR1. As a consequence of Plasmodium-induced caspase-1 activation, mice produced extremely high levels of IL-1beta upon a second …

Adverse Health Consequences Following Aerial Spraying With Bacillus Thuringiensis (Var. Kursraki) (Btk) To Control The Gypsy Moth: Flaws In Government Risk Assessments And In Public Health Officials' Attitudes, Richard B. Philp
Richard B. Philp
The soil bacterium Bacillus thuringiensis is noteworthy for its ability to infect fatally the digestive tract of moths, butterflies and other insects, making it an attractive biological agent to control insects that can damage crops and trees. One subspecies B. thuringiensis (var. kurstaki) is used in commercial preparations such as Foray 48B that can be applied as a spray on the ground or from aircraft. The latter approach is especially appealing as large areas can be sprayed at relatively low cost. The use of such spraying in populated, urban areas often results in reports of illnesses such as nausea, vomiting, …
