Setting Up a Patient Care Call Center After Potential HCV Exposure.

Objectives: Notify patients of a potential exposure to hepatitis C virus, coordinate testing, and provide follow-up counseling.

Methods: A team was convened to identify various needs in developing a patient care call center. The areas addressed included the following: location, hours, and duration; telephone accessibility; tracking calls and test results; billing; staffing; notification; and potential issues requiring additional evaluation.

Selected vaginal bacteria and risk of preterm birth: an ecological perspective.

We examined the community ecology of vaginal microbial samples taken from pregnant women with previous preterm birth experience to investigate whether targeted pathogenic and commensal bacteria are related to risk of preterm birth in the current pregnancy. We found a significant correlation between the community structure of selected bacteria and birth outcome, but the correlation differed among self-reported racial/ethnic groups. Using a community ordination analysis, we observed infrequent co-occurrence of Mycoplasma and bacteria vaginosis associated bacteria 3 (BVAB3) among black and Hispanic participants.

Gram stains: a resource for retrospective analysis of bacterial pathogens in clinical studies.

We demonstrate the feasibility of using qPCR on DNA extracted from vaginal Gram stain slides to estimate the presence and relative abundance of specific bacterial pathogens. We first tested Gram stained slides spiked with a mix of 10(8) cfu/ml of Escherichia coli and 10(5) cfu/ml of Lactobacillus acidophilus. Primers were designed for amplification of total and species-specific bacterial DNA based on 16S ribosomal gene regions.
