Evaluation of a nanophosphor lateral-flow assay for self-testing for herpes simplex virus type 2 seropositivity.

Herpes Simplex Virus Type 2 (HSV-2) is a common human pathogen that causes life-long illness. The US prevalence of HSV-2 infection is 11.9% for individuals between 15 and 49 years of age. Individuals with HSV-2 infection are more likely to contract and spread other sexually-transmitted infections. Eighty percent of individuals with HSV-2 are unaware of their infection, in part because of the social stigma associated with in-clinic testing for sexually-transmitted infections. We conducted an initial evaluation of a prototype smartphone-based serological lateral-flow immunoassay (LFA) for HSV-2 infection that uses strontium aluminate persistent luminescent nanoparticles (nanophosphors) as reporters. When applied to a test panel of 21 human plasma/serum samples varying in anti-HSV titer, the nanophosphor HSV-2 LFA had 96.7% sensitivity and 100% specificity for detection of HSV-2 infection. The sensitivity of the nanophosphor HSV-2 LFA was higher than that of commercially-available rapid HSV-2 assays tested with the same panel. Analysis of the iPhone nanophosphor HSV-2 LFA strip images with our custom smartphone app gave greater reproducibility compared to ImageJ analysis of strip images. The smartphone-based nanophosphor LFA technology shows promise for private self-testing for sexually-transmitted infections (STI).

A National Evaluation of Scholarly Activity Requirement in Osteopathic EM Residency Programs: Survey of EM Program Directors.

OBJECTIVES: The objectives of the study were to determine the percentage of osteopathic emergency medicine (EM) residencies that require an original research project to meet the American Osteopathic Association requirement, describe the resources available to the residents and faculty members to complete their projects, and determine resident and faculty research productivity. METHODS: This was a cross-sectional online survey of program directors from osteopathic EM residency programs. Participants were asked about demographics and specifics related to their program's research curriculum, which included resources, outcomes, and challenges. RESULTS: The response rate was 48.21% (27/56) of program directors from EM residencies. The majority (82.77%) of respondents were from a community-based EM program, had a requirement that a research project be completed before graduation from residency (87.5%), and did not have a research associate program to assist in recruiting patients (83.33%). A physician research director was noted to lead the department in 53.57% of respondents, whereas 70.83% noted having a statistician on staff. A total of 2.91% of program faculty had received federal grant funding, and 13.88% had a research study indexed in PubMed. EM programs that had a physician-led research director were more likely to have core faculty with federal funding, articles indexed in PubMed, residents who submit their research for publication, and residents with competitive grants, as compared with programs without a research director. Program directors noted that analyzing data, designing a study, and generating a hypothesis were the biggest challenges to conducting research in the residency. CONCLUSIONS: Osteopathic EM residencies significantly differ from their allopathic counterparts in their research curriculum, capabilities, and outcomes.
