Background: Epididymo-orchitis can be caused by sexually transmitted pathogens, including Neisseria gonorrhoeae, Chlamydia trachomatis, and Mycoplasma genitalium, or entero-bacteria. The aim of this study was to explore the demographics, microbiological findings, and treatment outcomes of patients presenting to a tertiary sexual health clinic with epididymo-orchitis. Methods: We reviewed the clinical notes of 200 randomly selected patients seen in the clinic with a diagnosis of epididymo-orchitis between 2021 and 2025. We extracted data on demographics, microbiological findings, follow-up, and clinical response rate to treatment. Results: The median age was 33 years (Interquartile range (IQR) = 24–44), 97 (49%) identified as MSM, 11 (6%) were living with HIV (all MSM), and 55 out of the 86 HIV-negative MSM (64%) were using HIV pre-exposure prophylaxis. In total, 35 (18%, 95% confidence intervals = 12.5–23.5%) people were diagnosed with a causative organism: 17 (9%) C. trachomatis, 10 (5%) N. gonorrhoeae, 7 (4%) M. genitalium, 3 (2%) Escherichia coli. Overall, 91 out of 200 (46%) had a documented partner notification plan. Conclusions: A minority of men attending our sexually transmitted infection clinic with clinical epididymo-orchitis have positive microbiology, including M. genitalium. More work is needed to understand the clinical pathophysiology of epididymo-orchitis to streamline treatment algorithms. Full article

Objective: To explore healthcare professionals’ beliefs and concerns about doxyPEP by systematically reviewing the literature. Method: A systematic review of three bibliographical databases (CINAHL, EMBASE and MEDLINE) and MedRxiv in August 2024, updated in February 2026 explored healthcare professionals’ beliefs and concerns about doxyPEP. Three researchers independently reviewed full-text manuscripts for eligibility and narratively synthesized data. We used the Joanna Briggs Institute toolkit to assess risk of bias. This review was registered on PROSPERO (ID:CRD42024570646). Results: Eight manuscripts were included in the final review: five cross-sectional studies, two qualitative studies, and one mixed method study from the USA (n = 5), Australia (n = 1), Kenya (n = 1), and the UK (n = 1) published between 2020–2025 and including 1840 healthcare professionals. Healthcare professionals recognised the high burden of bacterial STIs and believed that doxyPEP should be made available to MSM. There was a strong willingness to provide doxyPEP to MSM with the support of national guidelines. Healthcare professionals suggest that implementing doxyPEP would be feasible with educational support, but were concerned about antimicrobial resistance, drug–drug interactions, pill burden, cost, implementation logistics and the effect on clinical service demands. They acknowledged the lack of research and access to doxyPEP for other groups, specifically trans people and cis-gendered women. They also highlighted the need for community involvement in the implementation of doxyPEP. Conclusions: This review highlights that healthcare professionals were willing and ready to provide doxyPEP; however, they have concerns including antimicrobial resistance, the effect on service capacity, and the lack of research on cis-gendered women and trans people. Patients and health professionals need to be involved in the implementation of doxyPEP. Full article

Background: Since the onset of the HIV epidemic, over 40 million individuals have died from AIDS-related illnesses, leading to nearly 14 million children aged 0–17 losing one or both parents to AIDS by 2022. In 2023, Namibia had 250,000 vulnerable children and 72,000 children aged 0–17 orphaned due to HIV and AIDS. Without parental support, orphaned and vulnerable children (OVC) face heightened risks, including neglect, distress, and compromised decision-making. These vulnerabilities can increase their susceptibility to risky behaviors, such as sexual experimentation. This study used data from the Project HOPE Namibia (PHN) OVC program to assess HIV testing rates and associated factors among OVC. Methods: This retrospective cross-sectional secondary analysis study used data from PHN’s OVC program implemented from 1 August 2023 to 30 November 2024. Data were analyzed using Chi-square tests and binomial and multinomial logistic regression. Results: Among the 16,995 participants included in this analysis, 15,014 (88.3%) participants had ever been tested for HIV (95% confidence interval (CI): 87.8–88.8%). Participants with an increased likelihood of having ever tested for HIV included those who had been in the program for 0–6 months (adjusted odds ratio (AOR) = 1.31, 95% CI (1.17–1.47)), and those from households experiencing little or moderate hunger (AOR = 1.29, 95% CI (1.12–1.50), AOR = 1.51, 95% CI (1.33–1.72), respectively. Conclusions: A multi-pronged approach involving all stakeholders is required to increase HIV testing among OVC. Such an approach should include community-based HIV testing, providing male-friendly healthcare services, and reducing household hunger through economically empowering vulnerable households.

Background: The surveillance of antimicrobial-resistant (AMR) gonorrhea in the United States is conducted under the Gonococcal Isolate Surveillance Project (GISP). Its protocol involves the collection of urethral isolates from the symptomatic men diagnosed with urethral gonorrhea at designated surveillance sites and the estimation of the percentage of cases resistant to current and former gonorrhea antibiotics. A switch to a new antibiotic is typically made when this percentage for a current first-line drug reaches 5%. However, the cost-effectiveness of this surveillance strategy has never been assessed. Methods: We utilized our previously developed agent-based model of gonorrhea transmission among the US men who have sex with men (MSM) population and estimated the total number of gonorrhea cases, total number of discounted quality-adjusted life years (QALYs) and total discounted costs over 25 years under the current surveillance strategy and under a scenario with no surveillance. Results: The maintenance of the current surveillance strategy is projected to avert 104,108 (95% uncertainty interval: 9163, 213,238) gonorrhea cases, gain 192.9 (95% uncertainty interval: 6, 458.3) QALYs and save $38.6 million (95% uncertainty interval: $1 million, $68.2 million) in the simulated cohort of 10,000 US MSM over a 25-year period (2023–2048) when compared to a scenario with no surveillance. Conclusions: The current US surveillance strategy for AMR gonorrhea is cost-saving. However, the low-bound estimate indicates limited savings of $1 million, which is relatively modest at a national scale. Full article

Background/Objectives: Chemsex is defined as the intentional use of psychoactive substances to enhance or prolong sexual activity, predominantly observed among men who have sex with men. It has emerged as a notable behavioral and public health concern due to its association with high-risk sexual practices, psychiatric morbidity, and somatic complications. Despite increasing recognition, global prevalence estimates vary widely (3–52.5%) due to differences in study populations and methodology. Commonly used substances include synthetic cathinones, amphetamines/methamphetamines, MDMA, GHB/GBL, ketamine, alkyl nitrites, and PDE-5 inhibitors. Methods: A narrative review was conducted using PubMed through 11 December 2025. Search terms combined chemsex-related terminology, substance names, and health outcomes. Recent English-language publications (2020–2025) were prioritized. Evidence was synthesized thematically across epidemiology, health complications, motivations, and interventions. Results: Chemsex is strongly associated with unprotected sex, multipartner encounters, and prolonged intercourse, leading to significantly increased rates of HIV, syphilis, gonorrhoea, and chlamydia. Psychiatric complications include depression, anxiety, compulsive sexual behavior, and psychosis, with higher risks in individuals engaging in slamming or polysubstance use. Somatic complications vary by substance and include cardiovascular disease, hyponatremia, rhabdomyolysis, ulcerative cystitis, methemoglobinemia, and overdose. Motivational factors extend beyond sexual enhancement and include minority stress, internalized and externalized stigma, and maladaptive coping mechanisms. Integrated interventions combining harm reduction, cognitive–behavioral therapy, peer-led services, and pharmacotherapy, alongside digital health tools to support PrEP adherence and risk reduction, show promise in mitigating these harms. Conclusions: Chemsex represents a complex interplay of biological, psychological, and sociocultural factors that contribute to elevated STI risk and psychiatric and somatic morbidity. Addressing chemsex requires destigmatized, multidisciplinary approaches that integrate behavioral, pharmacological, and community-based interventions. Digital health innovations can further enhance engagement, risk reduction, and access to timely care. Full article

Background/Objectives: This study investigates the potential association between the sharp increase in syphilis cases in Japan and the growing popularity of dating apps, with a specific focus on the dynamics during the COVID-19 pandemic. Syphilis, a sexually transmitted infection (STIs) caused by Treponema pallidum, presents a significant global public health challenge despite being curable with antibiotics. In Japan, the incidence of syphilis has risen dramatically since 2013, surpassing 10,000 reported cases annually by 2022. Methods: To examine this trend, we analyzed the quarterly reported syphilis cases alongside active user data from three major dating apps (App1, App2, and App3) and conducted a stratified linear correlation analysis by gender and age group. Results: The results reveal that syphilis cases showed accelerated growth starting in the first quarter of 2021, and App 3 demonstrated the strongest positive correlation with new syphilis cases. The association was particularly significant among males aged 20–29 (R² = 0.70, p = 0.0007) and 30–39 (R² = 0.82, p < 0.0001). Conclusions: These findings suggest that the widespread use of dating apps may contribute to the rise in sexually transmitted infections, including syphilis, by facilitating extensive new sexual contacts. Notably, this trend became increasingly evident during the COVID-19 pandemic. Future STI prevention strategies should consider integrating dating apps as a potential medium for public health interventions. Additionally, strengthening sexual health services is essential to ensure that responses to global crises do not inadvertently undermine STI prevention and control efforts. Full article

Background/Objective: High-risk Human papillomavirus (hrHPV) is the leading cause of premalignant lesions and cervical cancer (CC), affecting disproportionally women living with HIV. Mozambique is among the countries with a heavy triple-burden of HIV, hrHPV infections and CC which accounts for more than 5300 new cases and 3800 deaths each year. In this study, we assessed the age-specific distribution and factors associated with hrHPV and cervical lesions among HIV-positive and -negative women from HPV-ISI (HPV Innovative Screening Initiative) study in Maputo, Mozambique. Methods: This cross-sectional study included 1248 non-pregnant women aged ≥18 years who attended CC screening at the DREAM Sant’Egídio Health Centre between July 2021 and April 2022. Screening involved visual inspection with acetic acid (VIA) and high-risk HPV DNA testing. Sociodemographic, lifestyle, and reproductive data were collected through a routine questionnaire. Logistic regression assessed associations between risk factors and hrHPV infection or cervical lesions. Age-specific hrHPV prevalence, partial HPV16/18 genotyping, and abnormal cytology rates were further analyzed by HIV status. Results: The mean age of participants was 43.0 ± 8.6 years. Overall hrHPV prevalence was 28.0%, being higher among HIV-positive women (46.8%) than HIV-negative women (23.8%). Non-16/18 hrHPV genotypes predominated across all age groups. VIA positivity was 11.1%, most frequently involving less than 75% of the cervical area and was more common among younger women (30–45 years) and those living with HIV. Increasing age was associated with lower odds of hrHPV infection (OR = 0.98, 95% CI: 0.97–1.00; p = 0.017), as was higher parity (≥3 deliveries vs. nulliparity: OR = 0.58, 95% CI: 0.36–0.94; p = 0.029). Contraceptive use (OR = 1.65, 95% CI: 1.15–2.38; p = 0.007) and a partially or non-visible squamocolumnar junction (SCJ) (OR = 2.88, 95% CI: 1.74–4.79; p < 0.001) were associated with higher odds of VIA positivity. Conclusions: hrHPV infection and cervical lesions were more frequent in younger and HIV-positive women, highlighting the need for strengthened targeted screening within HIV care services in Mozambique.

Background: In Bangladesh, a number of sex workers are involved in commercial sex work in different brothels in both legal and illegal settlements due to reasons such as lack of social support, depression, forced sex, abuse, violence, polyamory, being kidnapped, and unemployment. In this study, we tried to evaluate the demographic characteristics and prevalence of viral and sexually transmitted diseases (STDs) among the study population. Methods: A total of 250 female sex workers were interviewed and tested from the Daulatdia brothel of Rajbari district, Bangladesh, who had been working there for at least 1 month. Through questionnaires, demographic data were collected. Primarily, lateral flow immunoassay (LFIA) tests were used to investigate HCV (Hepatitis C Virus), HBV (Hepatitis B Virus), and Syphilis, which were reconfirmed using enzyme-linked immunosorbent assay (ELISA) in cases of positive results. Results: The mean age was 27.51 ± 6.69 years with a range of 18–50 years. Most of them (n = 243, 97.98%) had elementary knowledge of STDs. We determined that overall, 96 (38.40%) were positive for either of these diseases. Individually, 10 (4.00%), 18 (7.20%), and 68 (27.20%) were positive for HCV, HBV, and syphilis, respectively. Conclusions: Our observation indicates that females of all ages should be strictly protected from forced sex work. Current sex workers should be educated regarding the dangers and protective mechanisms of STDs. In addition, as a public health concern, regular clinical check-ups and STD associated diagnoses are necessary to ensure the safety of FSW from these highly infectious and concerning diseases. Due to their socio-economic condition, proper treatment and rehabilitation are highly recommended. Full article

Background: HIV is one of the deadliest viruses in the world and the leading cause of mortality and morbidity in the Sub-Saharan African countries, including Ethiopia. Millions of new HIV infections are reported every year among the population in the 15–24 age group. Particularly, adolescents are vulnerable to HIV infection due to a lack of adequate information and engagement in risky sexual practices. Thus, the assessment of knowledge, attitudes, and practices (KAPs) is one of the cornerstones in the fight against HIV/AIDS for designing appropriate prevention strategies. This study aimed to assess the KAPs regarding HIV/AIDS among high school students in Burayu town, Ethiopia. Methods: A cross-sectional study design was conducted on students from three higher secondary schools in Burayu town from February to June 2022. A total of 394 students were selected using a stratified proportional sampling technique. Data were collected using pre-tested and self-administered questionnaires and analyzed by SPSS version 26. Descriptive statistics were conducted, and logistic regression was used to determine the associations between variables. A p-value ≤ 0.05 was considered significant in all cases. Results: Out of the 394 students, the majority of respondents (70%) had sufficient knowledge about HIV/AIDS transmission and prevention, while only 61% demonstrated a positive attitude towards people living with HIV/AIDS (PLWHA). In bivariate analysis, a higher level of knowledge was significantly associated with a positive attitude towards PLWHA at OR 23.4, 95% CI, 2.9–185.5, p = 0.003, and not having had sexual practice at OR 4.1, 95% CI, 1.2–13.9, p = 0.025. In multivariate analysis, sexual practice was significantly (p ≤ 0.05) associated with the level of knowledge, age, gender, and places of residence at AORs values of 5.5, 9.7, 3.4, and 5.5, respectively. Conclusions: This study suggests that students with high levels of knowledge had a positive attitude towards PLWHA and less sexual practice compared to students with low levels of knowledge. Furthermore, students’ sexual practice was significantly associated with knowledge level, age, gender, and place of residence. This underscores the urgent need for targeted education to empower vulnerable groups, foster positive attitudes and practive, and curb HIV/AIDS transmission for improved health outcomes.

Background: Oral manifestations are common among people living with HIV (PLWH) and serve as important clinical indicators of immune status and disease progression. Despite extensive global research, data from the Gulf Cooperation Council region, particularly Saudi Arabia, remain limited. Aims: In this study, we aimed to determine the prevalence of oral manifestations, and their associations with immunological parameters, in a large cohort of PLWH in the Eastern Province of Saudi Arabia. Methods: In this cross-sectional study, we enrolled 1500 adult PLWH who attended the Dammam Medical Complex HIV Clinic between January and December 2023. Demographic, clinical, and laboratory data were collected through medical record review. Standardized oral examinations were performed once per participant by two calibrated dentists using World Health Organization criteria. Statistical analyses included descriptive statistics, chi-square tests, and independent t-tests, with significance set at p < 0.05. Results: The cohort had a mean age of 38.3 ± 11.5 years and was predominantly male (78.3%). Most patients (89.6%) were receiving antiretroviral therapy (ART), with 75.7% achieving viral suppression. The mean CD4 count was 527 ± 221 cells/μL. Common co-infections included hepatitis C virus (11.7%), tuberculosis (17.2%), and hepatitis B virus (4.3%). The prevalence of any HIV-related oral manifestation was 72.9% (n = 1093); the most common findings were xerostomia (subjective dry mouth sensation, 48.1%), oral candidiasis (21.6%), and periodontitis (42.7%). Among severely immunosuppressed patients (CD4 < 200 cells/μL, n = 114), 89.5% had oral manifestations, with oral candidiasis affecting 66.7%. Severe immunosuppression was strongly associated with ART-naive status (92.0% vs. 8.0%, χ² = 864.55, p < 0.001). The presence of HIV-related oral manifestations was significantly associated with CD4 count < 200 cells/μL (χ² = 15.96, p < 0.001). Conclusions: HIV-related oral manifestations remain highly prevalent in our large Saudi cohort, despite high ART coverage, with xerostomia and oral candidiasis as the predominant findings. Severe immunosuppression was strongly associated with both ART-naive status and opportunistic oral infections. The association between oral manifestations and immunosuppression underscores their continued clinical relevance as accessible indicators of disease status. Integration of routine oral health screening into HIV care is essential for comprehensive patient management in the region. Full article
