Vaginal Swab vs Urine for Detection of Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis: A Meta-Analysis

PURPOSE

Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) are the 2 most frequently reported notifiable sexually transmitted infections (STIs) in the United States, and Trichomonas vaginalis (TV), although not a notifiable disease, is the most common curable non-viral STI worldwide. Women bear a disproportionate burden of these infections and testing is necessary to identify infections. Although vaginal swabs are the recommended sample type, the specimen most often used among women is urine. The objective of this meta-analysis was to assess the diagnostic sensitivity of commercially available assays for vaginal swabs vs urine specimens from women.

METHODS

A systematic search of multiple databases from 1995 through 2021 identified studies that (1) evaluated commercially available assays, (2) presented data for women, (3) included data obtained from the same assay on both a urine specimen and a vaginal swab from the same patient, (4) used a reference standard, and (5) were published in English. We calculated pooled estimates for sensitivity and the corresponding 95% CIs for each pathogen as well as odds ratios for any difference in performance.

RESULTS

We identified 28 eligible articles with 30 comparisons for CT, 16 comparisons for NG, and 9 comparisons for TV. Pooled sensitivity estimates for vaginal swabs and urine, respectively, were 94.1% and 86.9% for CT, 96.5% and 90.7% for NG, and 98.0% and 95.1% for TV (all P values <.001).

CONCLUSIONS

Evidence from this analysis supports the Centers for Disease Control and Prevention's recommendation that vaginal swabs are the optimal sample type for women being tested for chlamydia, gonorrhea, and/or trichomoniasis.

Dental patients' communication preferences for learning about HPV-related topics

Oropharyngeal cancer (OPC) has the highest incidence of any cancer caused by human papillomavirus (HPV). Oral health providers are urged to support the use of the HPV vaccine, which was approved by the US Food and Drug Administration for the prevention of OPC in 2020. This study evaluated the preferences of dental patients regarding 11 modalities for learning about HPV-related topics from their oral health providers. An online survey was administered to US adults aged 18 to 45 years (n = 285) to assess their communication modality preferences, prior experience discussing HPV with oral health providers, and demographic characteristics. Multiple items were combined to obtain preference scores for each modality. Preference scores were compared using 2 × 3 mixed analysis of variance. Age, sex, income, and HPV vaccination status were assessed as potential confounders. One-on-one discussions were the most preferred modality for learning about HPV-related topics; however, the preference scores differed based on whether the patient had prior HPV-related discussions with oral health providers (partial η² = 0.054). Patients who had prior discussions showed a weaker preference for one-on-one discussions than did patients who had not had prior discussions. Oral health providers are called on to promote HPV vaccination, which will require increasing communication on this subject with patients. To assure greater acceptance of their recommendations, providers will need to match their communication styles to those desired by their patients. As part of a comprehensive HPV prevention strategy that includes administration of the vaccine, oral health providers should be educated on how to confidently discuss HPV-related issues with their patients.

ABSTRACT

The American Sexually Transmitted Diseases Association has, for several years, been conducting a cross-sector workshop to bring together a variety of stakeholders to develop ideas for collaboratively improving the sexually transmitted infection control efforts in the United States. In this summary, we share the content of discussions and ideas of the fourth annual workshop for future research and potential changes to practice with a focus on diagnostic capacity.

Making the Call: College Students' Legal Consciousness and Hypothetical Activation of Police for Sexual Assaults

Research has identified the necessity of sexual assault victims to label their experience as criminal to initiate reporting. However, barriers exist in labeling uninvited sexual contact as criminal. This study examined college students' assessments of whether eight nonconsensual behaviors met the legal definition of sexual assault, and whether such behaviors should be reported to police. Results indicated students acknowledged the nonconsensual behaviors as criminal; however, gaps were identified between awareness that the acts were criminal and willingness to report to police. Findings demonstrate a need for continued efforts for sexual assault prevention among college students.

Identifying Implementation Science Characteristics for a Prenatal Oral Health eHealth Application

Background. Oral health is a significant public health issue; yet barriers to implementing the prenatal oral health guidelines into practice remain. This formative research aimed to identify key implementation science characteristics to inform the development of an eHealth application (app) to assist providers in implementing the prenatal oral health guidelines during prenatal visits. Method. Guided by the Consolidated Framework for Implementation Research, the clinic's infrastructure, workflow, and contextual factors were assessed via clinic observation, technology assessment, prenatal provider interviews (n = 4), clinic staff interviews (n = 8), and two focus groups with oral health providers (n = 16). Results. System-level factors influencing future implementation were identified regarding structural characteristic, networks/communication, culture, external policy/incentives, relative advantage, complexity, design quality/packaging, knowledge/beliefs, and personal attributes. Discussion. Findings provided vital information and will directly inform the design and implementation of an eHealth app that aims to facilitate the translation of the interprofessional prenatal oral health guidelines into clinical prenatal oral health practices.

Are dental providers the next line of HPV-related prevention? Providers' perceived role and needs

The rise in HPV-related oropharyngeal cancer incidence necessitates novel prevention efforts including multiple provider types. Although dental providers screen for HPV-related oropharyngeal cancers, little is known about their needs to advance “primordial prevention,” or interventions at the earliest possible stage, to prevent HPV-related cancers. This study assessed dentists' and dental hygienists’ perceived roles and needs regarding HPV-related primordial prevention.

We conducted a mixed-method study with data from focus groups with dentists (n= 33) and dental hygienists (n= 48) and surveys from both provider types (n= 203) among providers from a diverse set of practice settings and geographic communities. Data were analyzed using qualitative thematic analysis and chi square tests.

Participants affirmed dental professionals’ roles in preventing HPV-related cancers and identified needs to overcome barriers to fulfilling prevention objectives. Barriers included: (1) practice environment and patient characteristics, and (2) the sensitive topic of HPV. Further, participants identified needs to improve HPV-related cancer prevention.

Findings from this study suggest that dental providers may become the next line of prevention for HPV-related cancers. Dental providers’ professional associations have provided guidance on HPV and oropharyngeal cancers, but our study reveals dental providers’ needs for following professional organizations’ guidance to advance prevention efforts and reduce HPV-related cancer incidence.

Support for Offering Sexual Health Services Through School-Based Health Clinics

BACKGROUND

Numerous studies document support for sexuality education in the schools. However, there is a dearth of research assessing support for sexual health services offered through school-based health clinics (SBHCs). The purpose of this study was to assess voter support for offering 3 sexual health services (STI/HIV testing, STI/HIV treatment, condom distribution) through SBHCs.

METHODS

The survey was developed after review of existing surveys on support for sexuality education and sexual health services. The university's Public Opinion Research Laboratory used random-digit-dialing to administer the survey to participants (N = 311) including residential and cell phone numbers.

RESULTS

Most participants were supportive of offering sexual health services at both middle schools (MS) and high schools (HS): testing for STIs/HIV (61% MS, 76% HS), treatment for STIs/HIV (60% MS, 75% HS), and provision of condoms (44% MS, 63% HS). Analyses showed significant differences in support for sexual health services by a few demographic variables, opinions about sexuality education, and the percentage of students perceived to have had sexual intercourse.

CONCLUSIONS

Results document support for offering sexual health services through SBHCs. These findings may benefit other communities looking to implement similar clinics. Such services have great potential for positively impacting the sexual health of youth.

Trends and predictors of HPV vaccination among U.S. College women and men

BACKGROUND

HPV vaccination was recommended by the Advisory Committee on Immunization Practices for young adult females in 2006 and males in 2011 to prevent HPV-related cancers and genital warts. As this prevention mechanism continues to disseminate, it is necessary to monitor the uptake of this vaccine. College students represent an important population for HPV vaccination efforts and surveillance due to increased risk for HPV infection and representing a priority population for catch-up HPV vaccination. The purpose of this study was to assess the trends in HPV vaccination among U.S. college females and males from 2009 to 2013, and to examine whether predictors for HPV vaccination differ between males and females.

METHODS

The National College Health Assessment-II (Fall 2009-2013) was used to assess trends in HPV vaccination using hierarchical logistic regression across genders and demographics. Data from 2013 were used to assess demographic variables associated with HPV vaccination for males and females, respectively. The analysis was conducted in 2015.

RESULTS

Females had nearly double the rates of HPV vaccination compared to males over time. All demographic sub-groups had significant increases in vaccine rates over time, with select male sub-groups having more accelerated increases (e.g., gay). Young age (18-21 vs. 22-26years) was a significant predictor for HPV vaccination among males and females, while race/ethnicity was a predictor of vaccination among females only.

CONCLUSIONS

These findings identified specific demographic sub-groups that need continued support for HPV vaccination. Campus health centers may be rational settings to facilitate clinical opportunities for HPV vaccination among unvaccinated college students.
