Self-care Decontamination within a Chemical Exposure Mass-casualty Incident.

Growing awareness and concern for the increasing frequency of incidents involving hazardous materials (HazMat) across a broad spectrum of contaminants from chemical, biological, radiological, and nuclear (CBRN) sources indicates a clear need to refine the capability to respond successfully to mass-casualty contamination incidents. Best results for decontamination from a chemical agent will be achieved if done within minutes following exposure, and delays in decontamination will increase the length of time a casualty is in contact with the contaminate. The findings presented in this report indicate that casualties involved in a HazMat/CBRN mass-casualty incident (MCI) in a typical community would not receive sufficient on-scene care because of operational delays that are integral to a standard HazMat/CBRN first response.

Establishing a community of practice of researchers, practitioners, policy-makers and communities to sustainably manage environmental health risks in Ecuador.

Background: The Sustainably Managing Environmental Health Risk in Ecuador project was launched in 2004 as a partnership linking a large Canadian university with leading Cuban and Mexican institutes to strengthen the capacities of four Ecuadorian universities for leading community-based learning and research in areas as diverse as pesticide poisoning, dengue control, water and sanitation, and disaster preparedness.

Methods: In implementing curriculum and complementary innovations through application of an ecosystem approach to health, our interdisciplinary international team focused on the question: "Can strengthening of institutional capacities to support a community of practice of researchers, practitioners, policy-makers and communities produce positive health outcomes and improved capacities to sustainably translate knowledge?" To assess progress in achieving desired outcomes, we review results associated with the logic framework analysis used to guide the project, focusing on how a community of practice network has strengthened implementation, including follow-up tracking of program trainees and presentation of two specific case studies.

Results: By 2009, train-the-trainer project initiation involved 27 participatory action research Master's theses in 15 communities where 1200 community learners participated in the implementation of associated interventions.

Bartonella species antibodies and DNA in cerebral spinal fluid of cats with central nervous system disease.

Bartonella species infection is associated with central nervous system (CNS) disease in some humans and cats but the diagnosis is difficult to confirm with blood or serum test results. In this retrospective study of 100 client-owned cats, serum and cerebral spinal fluid (CSF) were assayed for Bartonella species IgG antibodies and CSF was assayed for Bartonella species DNA. Bartonella species IgG antibodies were detected in serum of 36 cats, Bartonella species C-values>1 (suggesting antibody production by the CNS) were detected in CSF of 11 cats, and B henselae DNA was amplified from the CSF of 10 cats.

Prevalence of Bartonella henselae antibodies in serum of cats with and without clinical signs of central nervous system disease.

Bartonella henselae is occasionally associated with neurological dysfunction in people and some experimentally infected cats. The purpose of this study was to determine whether B henselae seroprevalence or titer magnitude varies among cats with neurological disease, cats with non-neurological diseases, and healthy cats while controlling for age and flea exposure. There was no difference in B henselae seroprevalence rates between cats with seizures and cats with other neurological diseases.
