Bacterial Vaginosis Incidence Following a Single Hyperosmolal Vaginal Lubricant Exposure: A Comparison of Two Observational Cohorts.
Sexually transmitted diseases ·doi:10.1097/olq.0000000000002184

BackgroundHyperosmolal lubricants may negatively affect the vaginal microenvironment, increasing the risk for bacterial vaginosis (BV). We compared the incidence of Amsel-defined BV in reproductive-age women exposed to hyperosmolal lubrican…

Uterine fibroids and longitudinal profiles of the vaginal microbiota in a cohort presenting for transvaginal ultrasound.
PloS one ·doi:10.1371/journal.pone.0296346

Bacterial vaginosis, characterized in part by low levels of vaginal Lactobacillus species, has been associated with pro-inflammatory cytokines which could fuel uterine fibroid development. However, prior work on the associations between ute…

Observational cohort study of the effect of a single lubricant exposure during transvaginal ultrasound on cell-shedding from the vaginal epithelium.
PloS one ·doi:10.1371/journal.pone.0250153

The outer layers of the vaginal epithelium (VE) are important because they accumulate glycogen which, under optimal conditions, Lactobacillus spp. consume to grow and acidify the vaginal microenvironment with lactic acid. We hypothesized th…
