Risk factors for human papillomavirus infection and disease: A targeted literature summary.

Adolescents are the primary cohort for routine human papillomavirus (HPV) vaccination, but unvaccinated adults may also benefit. A lack of consensus on which adults to target and the presence of reimbursement barriers likely contribute to the lag in adult vaccinations, highlighting missed prevention opportunities. Understanding factors contributing to risk of HPV infection and disease could help in decision making on vaccination. This review summarizes existing literature on risk factors for HPV infection and disease and includes 153 studies reporting relative risks or odds ratios for factors associated with HPV infection or disease in adults, published between 2009 and 2020. Despite inconsistent design and reporting of risk factors across studies, this review confirmed several risk factors associated with adult infection, including human immunodeficiency virus positivity, number of sex partners, and smoking. These findings can support policymaking, guideline development, and clinical decision making for HPV vaccination and screening of high-risk adult groups.

Is doxycycline post-exposure prophylaxis being utilised in Germany? Insights from an online survey among German men who have sex with men.

PURPOSE: Doxycycline post-exposure prophylaxis (Doxy-PEP) reduces the likelihood of Chlamydia and early syphilis by approximately two-thirds. Currently, data on the frequency of Doxy-PEP use in men who have sex with men (MSM) are limited. This study aimed to assess knowledge, attitude towards, and frequency of Doxy-PEP use among MSM in Germany. METHODS: We conducted a national online survey in Germany from summer to fall 2023, recruiting MSM and transgender women. Participants were invited to complete the online survey through social media, online dating platforms, and print media advertisements with active recruitment and poster advertising in private practices, tertiary outpatient clinics, and MSM community events in Germany. RESULTS: In total, 438 participants completed the survey and were included in the analysis, and 285 (65.1%) were living with the human immunodeficiency virus (HIV) or taking HIV-pre-exposure prophylaxis (PrEP). Overall, 170 participants (38.8%) had heard of Doxy-PEP, and 275 (62.8%) would consider taking it, but only 32 (7.3%) reported having ever taken Doxy-PEP. The most common reason for a negative attitude towards Doxy-PEP were apprehension about insufficient detailed information, and concerns about antibiotic resistance. Doxy-PEP users were more likely to be on HIV-PrEP, had a higher self-reported risk of bacterial sexually transmitted infections (STIs), and often had a history of bacterial STIs. CONCLUSION: The study demonstrated high awareness and strong interest in Doxy-PEP among MSM in Germany, most of whom were living with HIV or taking HIV-PrEP; however, the actual usage of Doxy-PEP remains low in the summer and fall of 2023.

The Great Mimicker: Secondary Syphilis-Associated Nephrotic Syndrome in an Adolescent Patient.

BACKGROUND: Syphilis is long regarded as the "great mimicker" for its variety of symptoms and clinical manifestations. Rarely, it can present with renal involvement, particularly nephrotic syndrome. This is an uncommon initial presentation, particularly in pediatrics. CASE REPORT: We present the case of a 17-year-old male adolescent who presented to the emergency department with a chief symptom of abdominal pain. In addition, he was found to have a number of stigmata characteristic of both syphilis and nephrotic syndrome, including a rash and diffuse edema, particularly in the lower extremities. This led to the diagnosis of nephrotic syndrome secondary to syphilis infection. Prompt diagnosis and treatment of syphilis resulted in resolution of both kidney injury and symptoms of the underlying infection. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case highlights the variety of manifestations of sexually transmitted infections, particularly in the pediatric population. It demonstrates how identifying syphilis as the inciting event led to the correct treatment management for the patient. This presentation serves to teach and remind emergency physicians of the wide-ranging presentations for sexually transmitted infections, particularly syphilis, and the necessity of obtaining a sexual history even in adolescent patients.

Community Pharmacy Chlamydia and Gonorrhea Test-To-Treat Program: Development of an Implementation Toolkit.

BACKGROUND: Sexually transmitted infection (STI) surveillance showed more than 2.5 million cases of chlamydia, gonorrhea, and syphilis nationally in the United States in 2022. Individuals often seek out non-emergency medical care at pharmacies. This makes community pharmacies well-positioned to address rising STI rates by offering services to screen and treat common STIs. A local health department, an independent pharmacy, and a school of pharmacy in Pennsylvania partnered to implement a test-to-treat service for chlamydia and gonorrhea within a pharmacy. This pilot program utilized: (1) patient self-collected test kits for chlamydia and gonorrhea screening and; (2) standing orders for treatment at the pharmacy. One goal of this pilot was to develop resources others can use to implement similar pharmacy-based chlamydia and gonorrhea testing and treatment services. OBJECTIVE: Develop an expert-informed implementation toolkit for a chlamydia and gonorrhea test-to-treat program at a community pharmacy. METHODS: The "How to Build an Implementation Toolkit from Start to Finish" framework from the University of California at Berkeley was used to design the initial toolkit outline. Toolkit content was triangulated from three sources: (1) comprehensive literature review; (2) pilot program implementation team meetings; and (3) feedback from public health and other experts. Pilot program partners met regularly to review and edit the toolkit. The draft toolkit was then reviewed by outside experts and potential end-users . RESULTS: An 11-item toolkit was developed. Toolkit contents were reviewed by 11 outside experts and potential end-users. Toolkit resources included STI training resources for pharmacy teams, testing and treatment standing orders, pharmacy treatment screening form, marketing strategies, patient education materials, sample workflow, essential supply list, and other key resources. CONCLUSION: Pharmacies may need additional resources for STI testing and treatment program implementation. Toolkit resources developed from this pilot program may help pharmacies overcome implementation barriers for similar programs.

A Position Statement on Mpox as a Sexually Transmitted Disease.

The global outbreak of mpox virus constituted an international public health emergency. Reports have highlighted (1) a temporal association between sexual activity and mpox, (2) an association between specific sexual practices and location of lesion development, (3) a high frequency of sexual practices conferring risk for other sexually transmitted infections among cases of mpox, (4) that mpox virus can be isolated from sexual fluids, (4) that isolated virus is infectious, and (5) a high frequency of anogenital lesions prior to disease dissemination suggesting direct inoculation during sexual activities. Finally, a growing body of evidence suggests that sexual transmission is the predominant mode of transmission for mpox virus. We therefore conclude that mpox is a sexually transmitted disease. Labeling it as such will help focus public health interventions, such as vaccinations, testing, and treatment, as well as facilitate focused awareness and education programs toward behavioral modifications to reduce exposures.

Timely Diagnosis of Incubating Syphilis Infections Using Treponema pallidum Transcription-Mediated Amplification Assay.

BACKGROUND: Syphilis is a complex, multistage, sexually transmitted infection (STI) caused by the bacterium Treponema pallidum subspecies pallidum (TP). New diagnostic tools are needed to minimize transmission. In this study, we aimed to assess the additional value of an investigational transcription-mediated amplification test for TP (TP-TMA) for routine diagnostics. METHODS: Between September 2021 and August 2022, visits by all participants of the national preexposure prophylaxis (PrEP) program at the sexual health center (SHC) in Amsterdam were included. Anal, pharyngeal, vaginal, and urine samples collected for Chlamydia trachomatis and Neisseria gonorrhoeae screening were additionally tested with the TP-TMA assay based on detection of 23S rRNA of TP. RESULTS: In total, 9974 SHC visits by 3283 participants were included. There were 191 infectious syphilis cases diagnosed: 26 (14%) primary syphilis, 54 (29%) secondary syphilis, and 111 (58%) early latent syphilis. In 79 of the 191 (41%) syphilis cases, at least 1 sample was TP-TMA-positive. For 16 participants, the positive TP-TMA result was not concordant with routine diagnostics. Of those, 2 participants were treated for syphilis within a week before the visit. Eight participants were treated for a syphilis notification at the visit or for another STI. Five participants were diagnosed with syphilis at the following visit, and 1 participant was lost to follow-up. CONCLUSIONS: By adding the TP-TMA assay to routine diagnostics, we identified 14 of 191 (7%) additional syphilis infections among participants of the national PrEP program. The TP-TMA assay is a useful diagnostic tool to increase syphilis case finding and thus limit the transmission of syphilis.

Estimation of the Lifetime Quality-Adjusted Life Years (QALYs) Lost Due to Syphilis Acquired in the United States in 2018.

BACKGROUND: The purpose of this study was to estimate the health impact of syphilis in the United States in terms of the number of quality-adjusted life years (QALYs) lost attributable to infections in 2018. METHODS: We developed a Markov model that simulates the natural history and management of syphilis. The model was parameterized by sex and sexual orientation (women who have sex with men, men who have sex with women [MSW], and men who have sex with men [MSM]), and by age at primary infection. We developed a separate decision tree model to quantify health losses due to congenital syphilis. We estimated the average lifetime number of QALYs lost per infection, and the total expected lifetime number of QALYs lost due to syphilis acquired in 2018. RESULTS: We estimated the average number of discounted lifetime QALYs lost per infection as 0.09 (95% uncertainty interval [UI] .03-.19). The total expected number of QALYs lost due to syphilis acquired in 2018 was 13 349 (5071-31 360). Although per-case loss was the lowest among MSM (0.06), MSM accounted for 47.7% of the overall burden. For each case of congenital syphilis, we estimated 1.79 (1.43-2.16) and 0.06 (.01-.14) QALYs lost in the child and the mother, respectively. We projected 2332 (1871-28 250) and 79 (17-177) QALYs lost for children and mothers, respectively, due to congenital syphilis in 2018. CONCLUSIONS: Syphilis causes substantial health losses in adults and children. Quantifying these health losses in terms of QALYs can inform cost-effectiveness analyses and can facilitate comparisons of the burden of syphilis to that of other diseases.

Changes in the Syphilis Rapid Plasma Reagin Titer Between Diagnosis and Treatment.

BACKGROUND: We compared the rapid plasma reagin (RPR) titer on the day of initial presentation with that on the day of syphilis treatment to inform clinical practice as to whether a repeated RPR test should be recommended. METHODS: We undertook a retrospective study between 1 March 2011 and 31 December 2020 at the Melbourne Sexual Health Centre in Australia among individuals who underwent syphilis serology on the day of initial presentation and the day of treatment, if the latter were within 14 days after initial presentation. We calculated the percentage of individuals with a ≥4-fold change in RPR titer, stratified by the time between initial presentation and treatment and by syphilis stage. RESULTS: Among the 766 included syphilis cases, the median duration between initial presentation and treatment was 6 days (interquartile range, 5-7 days). Of these cases, 14.8% (n = 113) had a ≥4-fold increase or decrease during this interval. The number of cases with a ≥4-fold increase or decrease in RPR titer increased with increasing time between initial presentation and treatment, from 5.7% (n = 6) 1-3 days after initial presentation to 26.2% (n = 27) at 10-14 days (Ptrend < .001). There was no significant difference in the number of cases with a ≥4-fold increase or decrease in RPR titer between syphilis stages (P = .66). CONCLUSIONS: Our data support the recommendation of repeating the RPR titer if the day of initial presentation and the day of treatment are different, even when treatment is within a few days after initial presentation.

The potential for bacteriophages and prophage elements in fighting and preventing the gonorrhea.

Bacteriophages are the most numerous entities on earth and are found everywhere their bacterial hosts live. As natural bacteria killers, phages are extensively investigated as a potential cure for bacterial infections. Neisseria gonorrhoeae (the gonococcus) is the etiologic agent of a sexually transmitted disease: gonorrhea. The rapid increase of resistance of N. gonorrhoeae to antibiotics urges scientists to look for alternative treatments to combat gonococcal infections. Phage therapy has not been tested as an anti-gonococcal therapy so far. To date, no lytic phage has been discovered against N. gonorrhoeae. Nevertheless, gonococcal genomes contain both dsDNA and ssDNA prophages, and viral particle induction has been documented. In this review, we consider literature data about the attempts of hunting for a bacteriophage specific for gonococci - the gonophage. We also discuss the potential application of prophage elements in the fight against N. gonorrhoeae. Temperate phages may be useful in preventing and treating gonorrhea as a scaffold for anti-gonococcal vaccine development and as a source of lytic enzymes with anti-gonococcal activity.

Incidence of sexually transmitted hepatitis C virus infection among men who have sex with men in Japan from 2009 to 2023.

Although the prevalence of hepatitis C virus (HCV) infection has decreased significantly with the advent of direct-acting antiviral agents, HCV is known to spread as a sexually transmitted disease among men who have sex with men (MSM), and this study aims to provide a perspective on the future prevalence of HCV in Japan. We examined incidence in two groups of MSM with HIV attending our institution in this retrospective cohort study, from 2009 to 2019 and from 2020 to May 2023 and investigated their background factors. Twenty-two cases were newly confirmed to be HCV infection in 2009-2019 and a total of 9 cases in 2020-2023, with an incidence rate of 5.04 per 1000 person-years in 2009-2019 and 5.55 per 1000 person-years in 2020-2023. All of them were diagnosed at routine outpatient visits for HIV, and few cases were considered to have symptoms of suspected hepatitis that led to a visit to the hospital and a diagnosis of HCV. Although HCV is still prevalent among MSM in Japan, it is possible that it would not have been diagnosed without testing at regular visits as in the case of people with HIV, and that the true prevalence rate among MSM, including non-HIV-infected persons, may be much higher.

Betapapillomavirus natural history and co-detection with alphapapillomavirus in cervical samples of adult women.

Human papillomaviruses (HPV) of the genus Betapapillomavirus can infect both cutaneous and mucosal sites, but research on their natural history at mucosal sites remains scarce. We examined the risk factors and co-detection patterns of HPVs of the Betapapillomavirus and Alphapapillomavirus genera in cervical samples of the Ludwig-McGill cohort study. We assessed a subset of 505 women from the Ludwig-McGill cohort study from São Paulo, Brazil. Cervical samples over the first year of follow-up were tested for DNA of over 40 alphapapillomavirus types and 43 betapapillomavirus types using a type-specific multiplex genotyping polymerase chain reaction assay. We assessed the risk factors for prevalent and incident betapapillomavirus type detection, and whether types were detected more frequently together than expected assuming independence using permutation tests, logistic regression, and Cox regression. We observed significant within-genus clustering but not cross-genus clustering. Multiple betapapillomavirus types were co-detected in the same sample 2.24 (95% confidence interval [CI]: 1.65-3.29) times more frequently than expected. Conversely, co-detections of alphapapillomavirus and betapapillomavirus types in the same sample occurred only 0.64 (95% CI: 0.51-0.83) times as often as expected under independence. In prospective analyses, positivity to one HPV genus was associated with a nonsignificant lower incidence of detection of types in the other genus. Lifetime number of sex partners and new sex partner acquisition were associated with lower risks of prevalent and incident betapapillomavirus detection. Betapapillomaviruses are commonly found in the cervicovaginal tract. Results suggest potentially different mechanisms of transmission for betapapillomavirus genital infections other than vaginal sex.

Is monkeypox a new, emerging sexually transmitted disease? A rapid review of the literature.

Monkeypox, a milder disease compared to smallpox, is caused by a virus initially discovered and described in 1958 by the prominent Danish virologist von Magnus, who was investigating an infectious outbreak affecting monkey colonies. Currently, officially starting from May 2022, an outbreak of monkeypox is ongoing, with 51 000 cases being notified as of September 1, 2022-51 408 confirmed, 28 suspected, and 12 fatalities, for a grand total of 51 448 cases. More than 100 countries and territories are affected, from all the six World Health Organization regions. There are some striking features, that make this outbreak rather unusual when compared with previous outbreaks, including a shift on average age and the most affected age group, affected sex/gender, risk factors, clinical course, presentation, and the transmission route. Initially predominantly zoonotic, with an animal-to-human transmission, throughout the last decades, human-to-human transmission has become more and more sustained and effective. In particular, clusters of monkeypox have been described among men having sex with men, some of which have been epidemiologically linked to international travel to nonendemic countries and participation in mass gathering events/festivals, like the "Maspalomas (Gran Canaria) 2022 pride." This review will specifically focus on the "emerging" transmission route of the monkeypox virus, that is to say, the sexual transmission route, which, although not confirmed yet, seems highly likely in the diffusion of the infectious agent.

The impact of human papilloma virus on human reproductive health and the effect on male infertility: An updated review.

It is believed that human papilloma virus infection (HPV), which is caused by the DNA virus, is the most prominent factor contributing to sexually transmitted disease (STD) in the world, with males having a prevalence rate of 3.5%-45% while that women are 2%-44%. Infertility is a rising problem on a global basis, affecting anywhere from 10% to 30% of couples who have reached reproductive age. This study aims to investigate the existing research on HPV, its connection to male infertility, and how it could be a helpful tool for medical professionals managing HPV in the context of reproductive health care. Infection with HPV has been identified as a risk factor for several spontaneous abortions; however, there is a lack of evidence on how HPV influences individuals undergoing assisted reproductive technology (ART) in terms of live births. The significance of the immune response to HPV-infected male reproductive system cells and its effect on embryos, as well as the oxidative stress generated by high-risk HPV DNA damage and genomic instability, is discussed in this review. Further, the association between male individuals infected with HPV and asthenozoospermia should provide a compelling case for vaccinating young people against HPV.

Marked reduction in the incidence of transfusion-transmitted hepatitis B virus infection after the introduction of antibody to hepatitis B core antigen and individual donation nucleic acid amplification screening in Japan.

BACKGROUND: In Japan, 41 million blood donations have been screened for hepatitis B virus (HBV) during the past 8.4 years using individual donation nucleic acid amplification testing (ID-NAT) and antibody to hepatitis B core antigen (anti-HBc) screening. STUDY DESIGN AND METHODS: Transfusion-transmitted HBV infection (TT-HBV) incidence was examined. Donated blood implicated in TT-HBV was analyzed for infection stage and DNA levels. Causative HBV strains were phylogenetically analyzed. RESULTS: Among 5162 (0.013%) ID-NAT positives, window period (WP) and occult HBV infection (OBI) accounted for 3.4% (176) and 11.5% (594), respectively. No OBI-related TT-HBV occurred. Seven blood donations caused eight TT-HBV cases, six of which were in the pre-ID-NAT WP, leaving one with an unresolved infection stage. Seven cases were caused by platelet concentrate (180 mL plasma) and one case by fresh-frozen plasma (200 mL plasma), which contained estimated infectious doses varying between 2 and 2300 HBV virions. HBV subgenotypes in five cases were HBV/A2. Complete genome sequences of the transmitting A2 strains were nearly identical (99.6%-100%) and clustered in a group that included HBV/HIV-1 coinfections and a higher proportion of donors in the acute infection phase (69%) than the other group of HBV/A2 sequences (5%). DISCUSSION: The incidence of observed TT-HBV cases has significantly reduced to 0.19 per million in the ID-NAT screening period. OBI-related TT-HBV was eliminated by anti-HBc screening. Established TT-HBV cases were caused by blood products with large plasma volumes containing extremely low HBV concentrations derived from blood donors at a very early infection stage.

Disparities in adherence to retesting guidelines in women with Trichomonas vaginalis infection.

BACKGROUND: Trichomoniasis is the most prevalent nonviral sexually transmitted infection in the United States. Numerous studies have shown disproportionately higher prevalence rates in non-Hispanic Black women. Because of the high rates of reinfection, the Centers for Disease Control and Prevention recommends retesting women treated for trichomoniasis. Despite these national guidelines, there are few studies examining adherence to retesting recommendations for patients with trichomoniasis. Adherence to retesting guidelines has been shown in other infections to be an important determinant of racial disparities. OBJECTIVE: This study aimed to describe Trichomonas vaginalis infection rates, evaluate adherence to retesting guidelines, and examine characteristics of women who were not retested according to the guidelines in an urban, diverse, hospital-based obstetrics and gynecology clinic population. STUDY DESIGN: We conducted a retrospective cohort study of patients from a single hospital-based obstetrics and gynecology clinic who were tested for Trichomonas vaginalis between January 1, 2015 and December 31, 2019. Descriptive statistics were used to examine guideline-concordant testing for reinfection among patients with trichomoniasis. Multivariable logistic regression was used to identify characteristics associated with testing positive and with appropriate retesting. Subgroup analyses were performed for patients who were pregnant and tested positive for Trichomonas vaginalis. RESULTS: Among the 8809 patients tested for Trichomonas vaginalis, 799 (9.1%) tested positive at least once during the study. Factors associated with trichomoniasis included identifying as non-Hispanic Black (adjusted odds ratio, 3.13; 95% confidence interval, 2.52-3.89), current or former tobacco smoking (adjusted odds ratio, 2.27; 95% confidence interval, 1.94-2.65), and single marital status (adjusted odds ratio, 1.96; 95% confidence interval, 1.51-2.56). Similar associated factors were found in the pregnant subgroup analysis. For women with trichomoniasis, guideline-concordant retesting rates were low across the entire population, with only 27% (214/799) of patients retested within the recommended time frame; 42% (82/194) of the pregnant subgroup underwent guideline-concordant retesting. Non-Hispanic Black women had significantly lower odds of undergoing guideline-recommended retesting than non-Hispanic White women (adjusted odds ratio, 0.54; 95% confidence interval, 0.31-0.92). Among patients tested according to guideline recommendations, we found a high rate of Trichomonas vaginalis positivity at retesting: 24% in the entire cohort (51/214) and 33% in the pregnant subgroup (27/82). CONCLUSION: Trichomonas vaginalis infection was identified at a high frequency in a diverse, urban hospital-based obstetrics and gynecology clinic population. Opportunities exist to improve on equitable and guideline-concordant retesting of patients with trichomoniasis.

Bactericidal activity of esculetin is associated with impaired cell wall synthesis by targeting glutamate racemase of Neisseria gonorrhoeae.

Neisseria gonorrhoeae (NG), the causative organism of gonorrhea, has been classified by the World Health Organization as 'Priority' two organism owing to its increased resistance to antibiotics and even failure of recommended dual therapy with ceftriaxone and azithromycin. As a result, the general and reproductive health of infected individuals is severely compromised. The imminent public health catastrophe of antimicrobial-resistant gonococci cannot be understated, as t he of severe complications and sequelae of infection are not only increasing but their treatment has also become more expensive. Tenacious attempts are underway to discover novel drug targets as well as new drugs to fight against NG. Therefore, a considerable number of phytochemicals have been tested for their remedial intercession via targeting bacterial proteins. The MurI gene encodes for an enzyme called glutamate racemase (MurI) that is primarily involved in peptidoglycan (PG) biosynthesis and is specific to the bacterial kingdom and hence can be exploited as a potential drug target for the treatment of bacterial diseases. Accordingly, diverse families of phytochemicals were screened in silico for their binding affinity with N. Gonorrhoeae MurI (NG-MurI) protein. Esculetin, one of the shortlisted compounds, was evaluated for its functional, structural, and anti-bacterial activity. Treatment with esculetin resulted in growth inhibition, cell wall damage, and altered permeability as revealed by fluorescence and electron microscopy. Furthermore, esculetin inhibited the racemization activity of recombinant, purified NG-MurI protein, one of the enzymes required for peptidoglycan biosynthesis. Our results suggest that esculetin could be further explored as a lead compound for developing new drug molecules against multidrug-resistant strains.

Monkeypox and Sexually Transmitted Diseases.

Monkeypox is a unique variety of pox infection. Despite being around for a long time, there hasn't been a large outbreak of this disease. WHO has already acknowledged the seriousness of the large monkeypox outbreak in 2022. Africa's unusual outbreak outside of endemic regions is a problem. Numerous observations have been made about the new clinical epidemiological pattern. Human monkeypox is currently spreading outside of endemic African countries, and the majority of those affected are gay and bisexual men in linked sexual networks. As was already mentioned, the current public health concern is the spread of monkeypox through sexual contact. The link between monkeypox and other sexually transmitted diseases is a growing concern because it is believed that the disease can be transferred through sexual contact. This page provides a summary of the interactions between other significant STDs such as HIV infection, syphilis, and gonorrhea. A fascinating research topic at the moment is the connection between monkeypox and other sexually transmitted diseases.

Chlamydia and Gonorrhea Testing Patterns Among Women with and Without Serious Mental Illness.

Rates of the sexually transmitted infections (STIs) Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) have risen in women by 13% and 40%, respectively, since 2015. Women with Serious Mental Illness (SMI) are at disproportionate risk for STIs. A retrospective chart review was performed at a safety-net healthcare system in the Southeastern United States (US) from 2014 to 2017. CT/GC positivity rates did not differ between the general and SMI populations (6.6% vs. 6.5% for CT and 1.8% vs. 2.2% for GC, respectively). Emergency Medicine accounted for more positive STI test results in SMI patients than the general population (25.2% vs. 19.1% for CT, 47.8% vs. 35.5% for GC, respectively). SMI patients received large portions of STI care in emergency settings, where follow-up is poor. Point of Care (POC) testing could improve care in this setting, and mental healthcare providers must address sexual health with patients who otherwise may not receive this care.

Do peer-based short-form educational videos created by nursing students improve youths' knowledge of sexually transmitted diseases? A quasi-experimental study.

BACKGROUND: The prevalence of sexually transmitted diseases (STDs) remains high worldwide in today's society, especially among young people. Youth education on STDs could help to reduce the prevalence of the condition in society and prevent new cases. AIM: The aim of this study is to assess the effectiveness of peer-based short-form educational videos on youths' knowledge of STDs. METHODS: This quasi-experimental study was conducted in Turkey. The sample consisted of 121 students divided into experimental and control groups. Pre- and post-test control group quasi-experimental research design was employed in this study during the spring semester of the academic year 2021-2022. Peer-based short-form educational videos created by nursing students were used as an intervention. The survey form and Sexually Transmitted Disease Knowledge Questionnaire were used to collect data. RESULTS: Participants with parental responsibilities and had previous STD experience had higher knowledge score than the other subgroups. There was a significant main effect of peer-based short-form educational video on participants overall knowledge score of STDs. Additionally, the effect of intervention continued at 12-week follow-up measurement. CONCLUSION: Peer-based short-form educational videos increase young people's knowledge of STD, and the impact of the intervention continued at 12-week follow up.

Assessing nonsexual transmission of the human papillomavirus (HPV): Do our current cleaning methods work?

Human papillomavirus (HPV) is thought to be sexually transmitted; however, there have been a few studies investigating a possible iatrogenic source of infection. Therefore, it is important to assess the cleaning methods of reusable medical devices. This study assessed whether cleaning methods of flexible endoscopes in an otolaryngology clinic are effective against HPV. There were 24 patients with a history of head and neck cancer in the study; however, two outliers were excluded. Nine patients were confirmed to have HPV-associated cancer. PCR was used to measure and quantify the viral genomes of samples collected before and after cleaning. After cleaning, few HPV+ samples had endoscopes with less DNA than before cleaning. Additionally, for several patients with non-HPV-associated head and neck cancer, PCR showed more DNA after cleaning than before cleaning, suggesting residual HPV DNA within the cleaning solution. There was no significant difference (p > 0.05) between pre- and post-cleaning in both cohorts. Current cleaning methods of reusable endoscopes may not be effective in completely removing viral DNA.
