Researchers are conducting an observational diagnostic study to develop and validate a new algorithm for diagnosing bacterial vaginosis and to evaluate the Nanopath assay, a molecular test that detects pathogens linked to vaginitis. The study focuses on individuals showing signs and symptoms of vaginitis and aims to compare the Nanopath assays performance with FDA-cleared commercial tests and yeast culture methods. Participants will provide vaginal swab specimens collected both by clinicians and by themselves. The study will assess the Nanopath assay, an amplification-free molecular test, alongside three FDA-cleared diagnostic tests BD Max14 Vaginal Panel, Cepheid Xpert4 Xpress MVP, and Hologic Aptima4 BV Assay, as well as yeast culture with MALDI-TOF for species identification. These comparisons will help validate the new diagnostic algorithm. During the study, participants will be asked to provide vaginal swab samples for analysis. Researchers will measure the accuracy of the Nanopath assay in diagnosing vaginal infections and compare the agreement between self-collected and clinician-collected samples. The study will collect data on symptoms and perform laboratory testing to evaluate diagnostic performance, with the primary outcome measured within one day of sample collection. Participants involvement includes sample collection and symptom reporting, with no treatment provided as part of this observational study.

This research aims to understand the role of unusual proteins, cytokines, and vaginal microbial flora in causing vulvodynia, recurrent fungal and bacterial vaginosis, and preterm labor. The study compares these factors in different groups of women to uncover how changes in the vaginal environment might lead to symptoms like irritation, pain, and infection recurrence, as well as premature birth. Researchers will use a multidisciplinary approach involving microbiology, proteomics, and cytokine analysis to explore these mechanisms. Participants include four groups of women aged 21 to 75 years healthy non-pregnant women without a history of vulvovaginal conditions, non-pregnant women with vulvovaginal issues, healthy pregnant women, and pregnant women with vulvovaginal conditions. Vaginal samples will be collected using cotton swabs from the middle vagina, processed for microbiological and biochemical testing including cytokine and protein levels. Pregnant women will have samples collected up to four times over 12 months. During the study, participants will provide informed consent and complete a comprehensive history related to environmental factors and vulvovaginal health. Researchers will measure cytokines, proteins, and vaginal lactobacillus levels from collected samples. Data will be kept confidential and stored securely. The main outcome is cytokine determination, with secondary outcomes including protein and lactobacillus analysis. The study aims to create a data bank to support future research, with participation lasting according to sample collection schedules.

Surgical site infections are a common problem in hospitals, especially after foot and ankle surgeries, where infection rates range from 0.4% to 3.6%. This research aims to evaluate whether adding a pre-scrub with isopropyl alcohol and chlorhexidine soap before the usual skin preparation can reduce microbial presence and surgical site infections. The study is a Phase 4 randomized trial sponsored by the University of Missouri-Columbia. Participants will be randomly assigned to one of two groups. The control group will have the standard skin preparation using iodine or chlorhexidine solution before surgery. The experimental group will receive this usual preparation plus an additional two-minute scrub of the limb with chlorhexidine soap and isopropyl alcohol applied and allowed to dry before sterile draping. During the study, participants will be monitored for 90 days after surgery to track surgical site infections and microbial load on the skin. Researchers will collect data on infection rates and bacterial presence to assess the effectiveness of the additional pre-scrub. This study includes adult patients undergoing elective foot and ankle surgeries, with follow-up visits or assessments scheduled as needed for safety and outcome measurements.
