Assessing Barriers to Human Papillomavirus (HPV) Vaccination in At-Risk Rural Communities of Western North Carolina, United States.

Human papillomavirus (HPV) vaccination among adolescents in rural, western North Carolina (NC) remains suboptimal. Data are needed to understand the barriers to HPV vaccination in these communities. We conducted a cross-sectional pilot study of parental attitudes and provider practices regarding HPV vaccination in rural western NC counties with lower HPV vaccination rates. Eight health department clinics were enrolled in the study. Further, 29 provider and 32 parent surveys were analyzed along with environmental scans. Median provider comfort regarding knowledge of HPV-associated diseases was 85% (IQR = 75-95), on a scale of 0-100% (100% representing complete comfort). Median parental comfort level regarding knowledge of HPV-associated diseases and the HPV vaccine was 75% (IQR = 50-89) and 75% (IQR = 49-96), respectively. Less than 25% of parents rated the HPV vaccine as 'extremely effective' against genital (16.7%) and anal cancers (17.9%). Parents were more likely to rate the vaccine as 'extremely effective' to 'very effective' if their child was female. There was no significant difference between parental- and provider-reported comfort with knowledge about HPV-associated diseases (p = 0.0725) and the HPV vaccine (p = 0.167). This study identified multiple opportunities to increase HPV vaccine coverage among unvaccinated adolescents at parental, provider, and clinic levels. Health education of rural NC residents and providers in public health settings may identify future interventions to increase HPV vaccine uptake.

Transkingdom Analysis of the Female Reproductive Tract Reveals Bacteriophages form Communities.

The female reproductive tract (FRT) microbiome plays a vital role in maintaining vaginal health. Viruses are key regulators of other microbial ecosystems, but little is known about how the FRT viruses (virome), particularly bacteriophages that comprise the phageome, impact FRT health and dysbiosis. We hypothesize that bacterial vaginosis (BV) is associated with altered FRT phageome diversity, transkingdom interplay, and bacteriophage discriminate taxa. Here, we conducted a retrospective, longitudinal analysis of vaginal swabs collected from 54 BV-positive and 46 BV-negative South African women. Bacteriome analysis revealed samples clustered into five distinct bacterial community groups (CGs), and further, bacterial alpha diversity was significantly associated with BV. Virome analysis on a subset of baseline samples showed FRT bacteriophages clustering into novel viral state types (VSTs), a viral community clustering system based on virome composition and abundance. Distinct BV bacteriophage signatures included increased alpha diversity along with discriminant Bacillus, Burkholderia, and Escherichia bacteriophages. Bacteriophage-bacteria transkingdom associations were also identified between Bacillus and Burkholderia viruses and BV-associated bacteria, providing key insights for future studies elucidating the transkingdom interactions driving BV-associated microbiome perturbations. In this cohort, bacteriophage-bacterial associations suggest complex interactions, which may play a role in the establishment and maintenance of BV.

Implementation of Oral and Rectal Gonococcal and Chlamydial Nucleic Acid Amplification-Based Testing as a Component of Local Health Department Activities.

From January 1, 2014, to May 31, 2015, 452 individuals received extragenital nucleic acid amplification-based Neisseria gonorrhoeae and Chlamydia trachomatis testing through public health venues. Seventy-four individuals (16%) tested positive for Neisseria gonorrhoeae and/or Chlamydia trachomatis at an extragenital site and 40 (54%) would not have been effectively diagnosed and treated in the absence of extragenital testing.
