Sexually transmitted infections among active component members of the U.S. Armed Forces, 2015-2023.

This report summarizes incidence rates and trends of sexually transmitted infections (STIs) from 2015 through 2023 among active component service members of the U.S. Armed Forces. The data compiled for this report are derived from the medical surveillance of chlamydia, gonorrhea, and syphilis as nationally notifiable diseases. Case data for 2 additional STIs, human papilloma virus (HPV) and genital herpes simplex virus (HSV), are also presented. The crude total case rates of chlamydia and gonorrhea initially rose by an average of 6.7% and 9.8% per year, respectively, until 2019. From 2020 onwards, rates steadily declined. By 2023, chlamydia rates had dropped by approximately 39%, while gonorrhea rates had fallen by more than 40% for female, and 19% for male, service members. Initially syphilis increased, on average, 10% annually from 2015 to 2019, then declined in 2020, but resumed its upward trend through 2023, nearly doubling the 2015 rate in 2023. The total crude annual incidence rates of genital HPV and HSV exhibited downward trends in general over the surveillance period, decreasing by 30.7% and 24.7%, respectively. Age- and gender-adjusted case rates for chlamydia, gonorrhea, and syphilis remain elevated within the U.S. Armed Forces compared to the general U.S. population, which may be due to factors that include mandatory STI screening, more complete reporting, incomplete adjustment for age distribution, and inequitable comparisons between the military active duty and general U.S. populations. Social restrictions enacted during the COVID-19 pandemic may have contributed to declines in true case rates and screening coverage.

Understanding Practical, Robust Implementation and Sustainability of Home-based Comprehensive Sexual Health Care: A Realist Review.

This review identifies which elements of home-based comprehensive sexual health care (home-based CSH) impacted which key populations, under which circumstances. A realist review of studies focused on home-based CSH with at least self-sampling or self-testing HIV and additional sexual health care (e.g., treatment, counseling). Peer-reviewed quantitative and qualitative literature from PubMed, Embase, Cochrane Register of Controlled Trials, and PsycINFO published between February 2012 and February 2023 was examined. The PRISM framework was used to systematically assess the reach of key populations, effectiveness of the intervention, and effects on the adoption, implementation, and maintenance within routine sexual health care. Of 730 uniquely identified records, 93 were selected for extraction. Of these studies, 60% reported actual interventions and 40% described the acceptability and feasibility. Studies were mainly based in Europe or North America and were mostly targeted to MSM (59%; 55/93) (R). Overall, self-sampling or self-testing was highly acceptable across key populations. The effectiveness of most studies was (expected) increased HIV testing. Adoption of the home-based CSH was acceptable for care providers if linkage to care was available, even though a minority of studies reported adoption by care providers and implementation fidelity of the intervention. Most studies suggested maintenance of home-based CSH complementary to clinic-based care. Context and mechanisms were identified which may enhance implementation and maintenance of home-based CSH. When providing the individual with a choice of testing, clear instructions, and tailored dissemination successful uptake of STI and HIV testing may increase. For implementers perceived care and treatment benefits for clients may increase their willingness to implement home-based CSH. Therefore, home-based CSH may determine more accessible sexual health care and increased uptake of STI and HIV testing among key populations.

Values of three-dimensional speckle tracking imaging for the diagnosis of coronary artery disease.

Background: Coronary artery disease (CAD) is a top life-threatening disease and early and sensitive detection of CAD remains a challenge. This study aimed to assess the value of three-dimensional speckle tracking imaging (3D-STI) in diagnosing CAD patients and investigate the parameters of 3D-STI associated with disease severity. Methods: A total of 260 suspected CAD patients who met the study criteria underwent coronary angiography within one week after the ultrasound examination. Based on the examination results, 142 patients were confirmed to have CAD (CAD group), while 118 patients were classified as non-CAD (NCAD group). Age, gender, family history, smoking status, diabetes, hypertension, dyslipidemia, electrocardiogram, BMI, heart rate, and left ventricular ejection fraction were compared between the two groups. Additionally, 3D-STI parameters including left ventricular global radial strain (GRS), left ventricular global longitudinal strain (GLS), left ventricular global area strain (GAS), and left ventricular global circumferential strain (GCS) were analyzed. Results: No significant differences were found between the CAD and NCAD groups in terms of demographics, smoking history, physiological measurements, and common comorbidities such as diabetes mellitus and dyslipidemia. However, when comparing the 3D-STI parameters, all four parameters, including GLS, GRS, GCS, and GAS, were significantly different in the CAD group compared to the NCAD group. The results suggest that 3D-STI parameters have diagnostic value for CAD, and their changes are associated with CAD severity. Conclusions: Combined detection of these parameters enhances diagnostic accuracy compared to individual detection.

Proportion of early treatment seeking for sexually transmitted infections and associated factors among patients attending youth friendly service in Bahir Dar City health centers, Northwest, Ethiopia.

BACKGROUND: Sexually transmitted infection is a common public health issue of youths and is characteristically transmitted through sexual intercourse. Even though early treatment for sexually transmitted infection is very important to reduce further complications and economic burden, studies to identify the proportion and the possible factor of early treatment seeking is rare in Ethiopia. OBJECTIVE: To assess the proportion of early treatment seeking for sexually transmitted infections and associated factors among patients attending youth friendly service in Bahir Dar city health centers, northwest, Ethiopia 2023. METHOD: Institutional based Cross-sectional study was used among 407 participants from April 25 to May 24 /2023. A systematic random sampling technique was used to select the participants. An interview-administered questionnaire was used for data collection, whereas Epi-data version 4.6.0.2 and the statistical package for statistical science version 23 were used for data entry and analysis respectively. A frequency table and bar chart were used for descriptive analysis. Multiple binary logistic regression was employed to identify the factors at p-value of <0.05. The necessary assumption of the model was also checked by the Hosmer and Lemishow test. RESULTS: The response rate of this study was 391 (96.1%) and the proportion of early treatment for sexually transmitted infection was 108 (27.6%, 95%CI; 23-32). Good knowledge about sexually transmitted infection (AOR=1.98, 95CI%; 1.13-3.47) know about their HIV status (AOR=1.95, 95%CI; 1.13-3.36), perceive severity of sexually transmitted infection (AOR=11.23, 95%CI; 6.15-20.45), and not fear the stigma about being infected with sexually transmitted infection (AOR=2.29, 95%CI; 1.32-3.96) were the significantly associated factors for early treatment of sexually transmitted infection. CONCLUSION AND RECOMMENDATION: The proportion of early treatment for sexually transmitted infection in Bahir Dar city was low. Knowledge about STIs, testing/ knowing HIV status, perception of the severity about sexually transmitted infection, and fear of stigma about sexually transmitted infection were the statistically significant factors for early treatment of sexually transmitted infection. So the government better give attention to health education and other health promotion activities to increase the knowledge of youths about sexually transmitted infection and to change their perception of sexually transmitted infection.

'Sometimes white doctors are not very friendly or inclusive': a Critical Race Theory analysis of racism within and beyond sexual health settings.

Many Two-Spirit, gay, bisexual, transgender, and other queer Black, Indigenous, people of colour in Canada encounter racism when testing for sexually transmitted and blood-borne infections. Our objective in this study was to understand how racism shapes testing experiences for these communities in Ontario, Canada. Four peer researchers conducted recruitment and data collection in consultation with a community advisory board. Focus groups and interviews took place with 21 participants and their narrative accounts were analysed using reflexive thematic analysis. Participants identified three interrelated issues when testing: (1) experiencing judgement and discomfort due to racism; (2) lack of community and cultural indicators in testing spaces; and (3) barriers to accessing testing centres and services. Systemic racism was linked to each of these barriers, including increased distance to testing centres due to racial segregation. Participant accounts signal the need for antiracist testing spaces and practices. Key implications include the need for antiracism training for health service providers and others working with Two-Spirit, gay, bisexual, transgender, and other queer Black, Indigenous, people of colour, and the organisations that serve them, in order to make testing spaces safer. Dismantling systemic racism is imperative to achieve health equity for members of these communities.

Concept Mapping STI/HIV Prevention and Condom Use among Young African American Adults.

Theory-based HIV prevention programs have resulted in increased condom use, which remains the best method for the prevention of sexually transmitted infections (STIs) among sexually active heterosexual individuals. Particularly, the integrative model of behavior prediction theorizes that attitudes, norms, self-efficacy, and socioenvironmental factors influence intention and behavior and has been useful in understanding STI risk among adolescents. However, more research is needed regarding young African American adults. Given the increased freedom and decision-making independence afforded to young adults compared to adolescents, it is important to consider the STI/human immunodeficiency virus (HIV) prevention messages that would resonate with them, particularly regarding condom use. The present study sought to explore how attitudes, subjective norms, self-efficacies, and socioenvironmental factors may influence condom use and STI/HIV prevention, as conceptualized by the participants. We conducted a group-based concept map, a systems-thinking mixed methodology that resulted in a geospatial map reflecting the conceptualizations of the participants. Self-identified young heterosexual African American adults (N = 43) aged 20-26 engaged in an interactive concept mapping procedure in order to "map out" their overarching concepts about STI/HIV risk and condom use. Seven overall conceptual domains emerged: self-efficacy for partner communication, condom use self-efficacy, social media/sociocultural influences, condom use/STI knowledge, condom use cons, condom use pros, and subjective and social norms about condom use. We presented the concept map and discussed the conceptual interpretations and the relationships among the overarching concepts. We also discussed how the social environment, including the social media environment, was conceptualized regarding STI/HIV risk and prevention among young African American adults. Concept mapping can be viewed as a way to determine worthwhile messages for intervention development. The findings may provide information for prevention programs aimed at reducing the incidence of STIs among young adult heterosexual persons within African American communities.

HIV-Negative MSM Infected with Two Different Isolates of Drug-Resistant Neisseria gonorrhoeae-Case Report.

The antimicrobial resistance of Neisseria gonorrhoeae (NG) is an increasing public health concern, highlighted by the fact that gonococcus is considered as a 'high'-priority pathogen by the WHO for research and development of new therapeutic options. According to the data of the European Centre for Disease Prevention and Control (ECDC) in 2022, the rate of NG infections is the highest recorded since European surveillance of sexually transmitted infections began in 2009. We report a brief description of a patient infected with two different isolates of drug-resistant N. gonorrhoeae. N. gonorrhoeae cultures were positive from oropharyngeal and urethral swabs and isolates had different antimicrobial susceptibility. We investigated the antimicrobial susceptibility of these isolates to six antimicrobials (ceftriaxone, cefixime, azithromycin, ciprofloxacin, tetracycline, and benzylpenicillin), and minimum inhibitory concentrations (MICs; mg/L) were determined using Etest on gonococcal isolates. Oropharyngeal isolate was resistant to azithromycin while urethral was resistant to penicillin, ciprofloxacin, and tetracycline. Two different and phylogenetically distinct sequence types of NG isolates were identified. Understanding the dynamics and drivers of resistance spread can provide an improved rationale for antibiotic management, and the level of NG resistance should be monitored closely.

Evaluation of the Sexually Transmitted Infections Programme among Key and Priority Populations in Primary Healthcare Facilities to Inform a Targeted Response: A Protocol Paper.

Primary healthcare facilities lack routine diagnostic screening due to resource limitations and dependence on syndromic management, resulting in an unprecedented prevalence and incidence of sexually transmitted infections (STIs), particularly among key and priority populations. Specific focuses are essential to strengthen current STI control measures. Therefore, this article describes the protocol for evaluating STI programme among key and priority populations in selected primary healthcare facilities in South Africa. We will employ an exploratory, descriptive research design to assess the STI programme in terms of its facility operations, functions, scope, gaps, delivery services, STI surveillance methods, and indicators in the selected primary healthcare facilities. A purposive sample of 15-20 STI programme stakeholders will be selected from five primary healthcare facilities in Limpopo Province, South Africa. The programme evaluation will use the World Health Organization assessment checklist tool, a globally recognised and validated instrument comprising open- and closed-ended questions to assess the STI programme. This tool, known for its credibility and reliability, ensures the study's validity. Quantitative data will be captured on STATA software (College Station, TX, USA) version 18 for descriptive analysis and presented as the mean and standard deviation for continuous variables, proportions and percentages for categorical variables. A p ≤ 0.05 will demonstrate a statistically significant level. Thematic content analysis will be conducted for the qualitative data using Atlas. ti software (Technical University, Berlin, Germany) version 23.1. The study's results will inform new approaches to strengthen STI coverage, service delivery, and linkage to care.

'Yeah, they suck. It's like they don't care about our health.' Medical mistrust among Black women under community supervision in New York city.

Black women in the USA experience some of the poorest health outcomes and this is especially true for those involved in the carceral system who are at elevated risks for HIV/STIs, reproductive health, and chronic diseases. This study aimed to investigate Black women's experience accessing healthcare services. We conducted semi-structured interviews with 43 women from Project EWORTH under community supervision in New York City. We analysed responses focusing on barriers to healthcare engagement. All interviews were recorded, and data analysis was conducted using NVivo. Themes influencing Black women's ability to engage with healthcare providers and systems included: 1) disclosed provider mistrust/judgement; 2) feeling disrespected by providers and the medical system; 3) mistrust of medical providers/system/hospital/government; 4) lack of health communication; 5) low health literacy; 6) provider gender preference. Findings highlight the need to improve trust and collaboration between healthcare providers and Black women. This study addresses the critical gap in understanding perceptions of discrimination, stigma, and barriers to attaining health care. Funders and accreditation agencies must hold providers and organisations accountable for acquiring and making available diversity, equity and inclusion training for providers, demonstrating increasingly equitable medical relationships through responsiveness to patient feedback, and increasing the number of Black providers.

Preventing Behavioral Human Immunodeficiency Virus Infections in Adolescents and Young Adults.

HIV prevention in adolescents and young adults (AYA) requires a multi-pronged strategy encompassing behavioral, biologic, and structural approaches. This article reviews the epidemiology of HIV infection in the United States and its pathogenesis and transmission. Prevention approaches are discussed in more detail, with an emphasis on how each approach is relevant to AYA populations. Information is summarized in a resource table with links to references and in-depth discussions of the topics reviewed in this article.

Overcoming analytical and preanalytical challenges associated with extragenital home collected STI specimens.

Home sample collection for sexually transmitted infection (STI) screening options can improve access to sexual healthcare across communities. For Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG), genital infections have classically been the focus for remote collection options. However, infections may go undiagnosed if sampling is limited to urogenital sites because some individuals only participate in oral and/or anal intercourse. Here we evaluated samples for CT/NG detection after several pre-analytical collection challenges. A paired provider to self-collection validation was performed on rectal [n = 162; 22 + for CT and 9 + for NG by provider-collected (PC)] and throat (N = 158; 2 + for CT and 11 + for NG by provider-collected) swabs. The positive percent agreement for CT and NG ranged from 90.9% to 100%. The discrepancies were more often positive on self-collected (SC) (n = 9 SC+/PC-; n = 1 PC+/SC-; n = 1 PC+/SC Equiv.; n = 2 PC-/SC Equiv.). An empirical limit of detection (LoD) lower than the manufacturer's claim (0.031 vs 2.5 IFU/mL for CT and 0.063 vs 124.8 CFU/ml for NG, respectively) was used to challenge additional variables. Common hand contaminants, including soap, hand sanitizer, lotion, and sunscreen were added to known positive (3× empirical LoD) or negative samples and did not influence detection. Samples at 2× and 10× the empirical LoD were challenged with extreme temperature cycling and extended room temperature storage. Detection was not affected by these conditions. These results indicate that remote self-collection is an appropriate method of sample acquisition for detecting extragenital CT/NG infections. Additionally, they provide a foundation towards meeting the regulatory standards for commercial testing of home collected extragenital samples. IMPORTANCE: There is a clinical need for expanded extragenital bacterial sexually transmitted infection (STI) testing options, but the current regulatory landscape limits the wide-spread promotion and adoption of such services. Improved access, particularly for the LGBTQ+ community, can be achieved by validating testing for specimens that are self-collected at a remote location and arrive at the laboratory via a postal carrier or other intermediary route. Here we provide valuable data showing that self-collected samples for anal and oropharyngeal STI testing are equally or increasingly sensitive compared with those collected by a provider. We systematically consider the effects of storage time, exposure to temperature extremes, and the addition of common toiletries on results.

The Influence of Housing Status and Food Insecurity on a Behavioral HIV/STI Prevention Intervention for Black Women under Community Supervision in New York City: A Moderation Analysis.

Black women in community supervision programs (CSPs) are disproportionately affected by HIV and other sexually transmitted infections (STIs). A randomized controlled trial of a group intervention titled Empowering African-American Women on the Road to Health (E-WORTH) demonstrated effectiveness in reducing sexual risk behaviors and STI incidence among Black women in CSPs. This secondary analysis aimed to assess the moderating effects of housing status and food security on E-WORTH effectiveness in reducing sexual risk behaviors and cumulative incidence of STIs over a 12-month period which were found significant in the original trial among a sample of 351 Black women in CSPs in New York City who use drugs and/or engage in binge drinking who reported engaging in HIV risk behaviors or testing positive for HIV. We examined the moderating effects of housing stability, housing independence, and food insecurity on reducing cumulative STI incidence and number of unprotected sex acts using mixed-effects negative binomial regression and logistic regression models that controlled for age, high school education, employment status, and marital status. Findings indicate that the intervention effect was moderated by housing stability, but not housing independence or food security. Compared to the control group, E-WORTH participants who were housing insecure had 63% fewer acts of condomless sex. Our findings highlight the importance of interventions designed for women in CSPs that account for upstream determinants of health and include service linkages to basic needs provisions. Further research is needed to unpack the cumulative impacts of multiple experiences of poverty faced by this population.

STI/HIV testing, STIs, and HIV PrEP use among men who have sex with men (MSM) and men who have sex with men and women (MSMW) in United States, 2019-2022.

BACKGROUND: Routine sexually transmitted infection and human immunodeficiency virus (STI/HIV) testing and HIV pre-exposure prophylaxis (PrEP) use are recommended for men who have sex with men (MSM) at increased risk of HIV. METHODS: Using Healthverity, a large administrative dataset in the United States, we assessed STI/HIV testing, chlamydia and gonorrhea positivity by specimen type, and HIV PrEP use among MSM and men who have sex with men and women (MSMW) at their first visits (index date) for those at increased risk of HIV and STIs from 2019 through 2022. RESULTS: Among 81,716 MSM and MSMW aged 15-64 years at their index date visit, STI testing rates were 57.9% for chlamydia, 58.1% for gonorrhea, and 52.2% for syphilis testing, respectively; 55.5%, 30.9%, and 18.1% had HIV testing, HIV PrEP use, and PrEP initiation, respectively, among the patients who did not have HIV. Of patients with chlamydia and gonorrhea testing, 48% were tested from the genital site only and 25% from three anatomic sites (rectal, pharyngeal, and urogenital). Chlamydia and gonorrhea positivity was 9.8% for chlamydia rectal infection, 7.3% for gonorrhea rectal infection, and 5.3% for gonorrhea pharyngeal infection. CONCLUSION: Our results present current medical services provided during initial clinic visits for MSM and MSMW in private outpatient settings. Our study suggests that the assessment of STI/HIV testing is periodically needed due to the high prevalence of infection, and efforts to promote HIV PrEP for MSM and MSMW in private settings are urgently needed.

Understanding male circumcision: insights from a peri-urban community in Maputo City, Mozambique.

BACKGROUND: Circumcision is a protective measure against sexually transmitted infections (STIs), reducing the risk of HIV infection. This study reported coverage of male circumcision and assessed the factors associated with male uncircumcision in a peri-urban area in Maputo City, Mozambique. METHODS: This cross-sectional study of the Health Demographic Surveillance System in the Polana Caniço neighborhood investigated the sociodemographic and behavioral factors associated with uncircumcised males aged 15-49 y from October 2019 to June 2021. Data were collected from an HIV risk factors questionnaire and descriptive analyses conducted comparing self-reported male circumcision status by sociodemographic factors and sexual behaviors. The association was assessed via χ2 tests, and a multivariable logistic regression model was constructed. Adjusted ORs and 95% CIs were reported for factors associated with uncircumcised status. RESULTS: Of the 3481 males aged 15-49 y who responded to the questionnaire, 79.5% (2766) self-reported being circumcised. The percentage of uncircumcised men steadily increased with age, ranging from 12.4% (95) among males aged 15-19 y to 34.5% (148) of men aged 40-49 y. Men without education or with primary education, as well as those not practicing Islam, were 3-4 times more likely to be uncircumcised. Uncircumcised men were more likely to self-report an STI and a lack of condom use. CONCLUSIONS: Being uncircumcised was associated with not using condoms and having STIs, highlighting the need to further emphasize combination HIV-prevention programs and regular HIV/STI screening. Targeting males with lower education and across religions can help reach those with lower coverage of this effective prevention intervention.

Ocular Syphilis as a Primary Manifestation of Neurosyphilis: A Case Report.

Sexually transmitted infectious diseases could affect a variety of organs, generating significant symptomatology. In the elderly population, infectious causes for vision problems are not generally considered. We present the case of an elderly patient with blurred vision and darkening of visual fields. He underwent an unsuccessful biopsy of the temporal artery as his vision disturbances presented also with episodic headaches. He was found to have an elevated rapid plasma reagin (RPR) and venereal disease research laboratory (VDRL) test in his cerebrospinal fluid (CSF) analysis. He was treated for ocular syphilis with a total resolution of his vision loss.

A Rare Case of Lymphocytic Ascites.

Ascites can manifest as a result of many conditions, with cirrhosis being the most common cause in the United States. Here, we present a case of lymphocytic ascites, a less common variant that occurred due to infection with Chlamydia trachomatis. This was a 37-year-old female with a history of substance and sexual abuse who presented with the chief complaints of abdominal pain, abdominal distension, and weight gain. She was febrile on admission with a distended, tender abdomen. The more common cardiac, renal, and hepatic causes were ruled out with extensive workup. Diagnosis and therapeutic paracentesis were done with fluid analysis significant for lymphocyte predominance and absence of malignant cells. Multi-modal imaging had ruled out suspicious malignant masses but CT abdomen/pelvis did show complex large volume ascites. Urine chlamydia and gonorrhea polymerase chain reaction (PCR) had resulted positive for chlamydia, leading us to start Doxycycline. Other infectious workups were negative, but ascitic fluid chlamydia NAAT was positive. Though initially worsening, the patient started showing significant clinical improvement after starting doxycycline, with the resolution of ascites and associated symptoms. This case report intends to bring to attention the importance of testing for chlamydia infection in cases of lymphocytic ascites, especially in sexually active females.

The Impact of the COVID-19 Pandemic on STI and HIV Services in the Netherlands According to Health Care Professionals.

Surveillance data from the Netherlands show that STI/HIV testing decreased at the start of the COVID-19 pandemic, suggesting barriers to access to STI/HIV care. However, the impact of the pandemic on STI/HIV care may be more complex, and key populations could be differentially affected. The aim of this study was to gain more insight into the impact of COVID-19 on STI/HIV care in the Netherlands from the perspective of STI/HIV care providers. We investigated whether professionals in STI/HIV care experienced changes compared to pre-COVID in access to STI/HIV care for priority populations, demand and provision of STI/HIV care, shifts to online STI/HIV counseling and care, and the quality assurance of STI/HIV care. An online survey was completed by 192 STI/HIV care professionals. Additionally, semi-structured interviews were held with 23 STI/HIV care professionals. According to participants, people in vulnerable circumstances, such as recent migrants and people with low health or digital literacy, may have had difficulties accessing STI/HIV care during the pandemic, especially during lockdowns and at public sexual health services. Hence, these may not have received the care they needed. Participants thought that COVID-19 measures may have compounded existing disparities. Furthermore, participants found that online care provision was not up to standard and were concerned about follow-up care for patients using private online providers of remote tests. It is important to explore how STI/HIV care for people in vulnerable circumstances can be ensured in future public health crises.

Varying behavioral differences and correlates of HPV infection among young adolescents in Benue state, Nigeria.

BACKGROUND: Human Papillomavirus (HPV) infection is a significant public health concern globally, especially in low- and middle-income countries. In Africa, including Nigeria, HPV prevalence is high, contributing to a substantial burden of cervical cancer. Despite challenges, massive HPV vaccination campaigns in Africa show promise for preventing cervical cancer cases. In Benue State, Nigeria, limited research exists on several aspects of HPV knowledge and attitudes towards HPV among secondary school students. This study aims to bridge this gap by assessing HPV knowledge, prevention practices, willingness to uptake HPV vaccination, and associated attitudes and behaviors among secondary school students in the state. METHODS: The cross-sectional study was conducted among adolescents aged 10-19 years in six secondary schools in three local government areas (LGAs) in Benue State, Nigeria. Two-stage sampling was used to select the LGAs and schools, with a final sample size of 591 students. The selected schools represent both junior and senior secondary school levels and span across the three senatorial districts of the state. Data were collected using a self-administered questionnaire covering sociodemographic characteristics, HPV knowledge, prevention practices, and willingness for HPV vaccination. Statistical analyses included univariate analyses and tests of association, with significance set at p < 0.05 or 0.001 depending on the level of the stringency of the evidence required. Data were analyzed using SPSS version 25. RESULTS: Only 35.4% of the participants were males, and 86.8% were between the ages of 10 and 16. Only 24.7% acknowledged that HPV can be transmitted during sexual intercourse, and 36.2% recognized that HPV can be transmitted via skin-to-skin contact. 48.1% noted that HPV can cause cervical cancer. Half (50.9%) acknowledged that early sexual debut increases the risk of acquiring HPV, while only 28.1% recognized vaccination as a preventive strategy against HPV infection. Only 35% correctly stated the best time for the HPV vaccine. In assessing the practice of HPV prevention, 14.9% are in a sexual relationship and 10.3% admitted to not using condoms during sexual intercourse. Also, 11.8% have had STIs, and 27.2% have previously undergone HIV screening. Various bivariate analyses showed some varying behavioral differences and correlates of HPV infection among young adolescents in Benue State, Nigeria. CONCLUSIONS: This study provides valuable insights into HPV knowledge, prevention practices, and willingness to uptake HPV vaccination among secondary school students in Benue State, Nigeria. The significance of the differences and correlates was discussed using themes. The research has unpacked complex relationships that could have public health implications for researchers and policymakers. Moreover, ten actionable policy recommendations were prescribed. Several interventions and areas for further study were proposed.

Advances in Chlamydia trachomatis Vaccination: Unveiling the Potential of Major Outer Membrane Protein Derivative Constructs.

Chlamydia (C.) trachomatis, a leading cause of sexually transmitted infections (STIs) worldwide, continues to be a significant public health concern. The majority of infections are asymptomatic and, when left untreated, severe sequelae such as infertility and chronic pelvic pain can occur. Despite decades of research, an effective vaccine remains elusive. This review focuses on the potential of Major Outer Membrane Protein (MOMP)-derived constructs as promising candidates for C. trachomatis vaccination. MOMP, the most abundant protein in the outer membrane of C. trachomatis, has been a focal point of vaccine research over the years due to its antigenic properties. To overcome issues associated with the use of full MOMP as a vaccine antigen, derivative constructs have been studied. As these constructs are often not sufficiently immunogenic, antigen delivery systems or accompanying adjuvants are required. Additionally, several immunization routes have been explored with these MOMP-derived vaccine antigens, and determining the optimal route remains an ongoing area of research. Future directions and challenges in the field of C. trachomatis vaccination are discussed.
