Hepatitis C in a sexually transmitted infection clinic in Barcelona, Spain: analysis of the last decade.

OBJECTIVES: Hepatitis C virus (HCV) remains a global health concern, particularly among gay, bisexual and other men who have sex with men (GBMSM) with HIV or receiving HIV pre-exposure prophylaxis (PrEP). This study describes the sociodemographic, clinical and behavioural characteristics of HCV cases diagnosed at our clinic over a 10-year period and explores potential transmission networks. METHODS: Retrospective, descriptive, single-centre study including epidemiological, behavioural and clinical characteristics of HCV cases diagnosed at a Sexually Transmitted Infections (STI) Unit in Barcel

Barriers and Facilitators of the Uptake of Human Immunodeficiency Virus (HIV) Services Among Transgender Women: A Mixed-Methods Study in Delhi, India.

BACKGROUND: Transgender women face higher human immunodeficiency virus (HIV) risk due to stigma, social marginalization, and high-risk behavior. AIM: This study aimed to explore the barriers and facilitators to HIV service uptake among transgender women to improve healthcare access. METHODOLOGY: A mixed-methods study was conducted among transgender women in Delhi, India. Data were collected from March to August 2023, using both quantitative and qualitative approaches. The quantitative study involved 170 participants from targeted intervention (TI) sites, focusing on sociodemographic characte

Unveiling the prevalence of sexually transmitted infections and its etiology among married women of remote South Andaman Island in India.

Sexually transmitted infections (STIs) are a global public health concern, particularly among women of reproductive age and leads to severe health complications. Married women, despite being perceived as low-risk, are often excessively affected due to factors such as partner infidelity, and lack of negotiation power in sexual relationships. Therefore, the study aimed to understand the prevalence of STIs among married women of South Andaman Islands. A cross-sectional study with an analytical focus was conducted on STIs in South Andaman after obtaining the ethical approval. Written informed cons

Behavioral and Structural Interventions for PrEP Adherence Among Young Female Sex Workers from Western Kenya.

HIV incidence is high among young female sex workers (YFSW) in Kenya. Pre-exposure prophylaxis (PrEP) for HIV prevention is recommended for at-risk populations, but its effectiveness requires consistent access and adherence. The IPrEP study compared the feasibility, acceptability, and effectiveness of two adherence support interventions on PrEP adherence among YFSW in Kisumu, Kenya. Study follow-up coincided with national restrictions on travel and gatherings due to the COVID-19 pandemic. We conducted an unblinded, randomized-controlled trial enrolling 18-24 year-old HIV-negative YFSW with no

Lymphogranuloma Venereum (LGV) Proctocolitis Presenting As Small Bowel Obstruction in an HIV-Negative Man Who Has Sex With Men (MSM) on Pre-exposure Prophylaxis (PrEP): A Diagnostic Dilemma.

Lymphogranuloma venereum (LGV) is an aggressive, sexually transmitted infection caused by specific serovars (L1-L3) of Chlamydia trachomatis. Historically considered endemic to tropical regions, LGV has re-emerged in developed nations in recent decades, predominantly affecting men who have sex with men (MSM). Its clinical spectrum is broad, ranging from asymptomatic infection to severe proctitis and proctocolitis, as well as systemic inflammatory manifestations. While buboes were once the hallmark presentation, proctitis syndrome has become the predominant clinical form in contemporary MSM pop

Ceftriaxone-resistant Neisseria gonorrhoeae in Singapore: Eight years of sentinel surveillance.

BackgroundCeftriaxone is currently the most frequently recommended first-line therapy for gonorrhoea globally. The emergence of ceftriaxone-resistant Neisseria gonorrhoeae threatens effective control, yet longitudinal surveillance data remain limited in many settings. Sentinel gonococcal antimicrobial resistance surveillance has been conducted at the Department of STI Control (DSC), Singapore, since 2014. We report findings on the emergence of ceftriaxone-resistant Neisseria gonorrhoeae detected between 2018 and 2025.MethodsWe conducted an analysis of longitudinal sentinel laboratory surveilla

Reassessment of public awareness and prevention strategies for HIV and COVID-19 co-infections through epidemic modeling.

A co-infection model between HIV and COVID-19 that takes into account COVID-19 vaccination and public awareness is discussed in this article. Rigorous analysis of the model is conducted to establish the existence and local stability conditions of the single-infection models. We discover that when the corresponding reproduction number for COVID-19 and HIV exceeds one, the disease continues to exist in both single-infection models. Furthermore, HIV will always be eradicated if its reproduction number is less than one. Nevertheless, this does not apply to the single-infection COVID-19 model. Even

"I have the vaccine in my body": perceptions of female sex workers after enrolling in a phase IIb HIV vaccine and pre-exposure prophylaxis trial in urban Tanzania.

BACKGROUND: HIV continues to be a significant global public health problem in low and middle-income countries. Efforts to search for an effective and affordable preventative HIV vaccine are on-going. We investigated the understanding of perceived risk for acquiring HIV and the experience of female sex workers (FSW) in Tanzania, before and after enrolling in an HIV vaccine and Pre-Exposure Prophylaxis Trial. METHODS: This was a descriptive qualitative study design nested in a multicentre Phase IIb three-arm, two-stage HIV prophylactic vaccine trial with a second randomization to compare two pr

Prevalence of hepatitis B virus infection and associated factors among students living on campus in South-eastern Gabon.

BACKGROUND: The Hepatitis B-virus is the etiological agent of an infection that affects liver functions and potentially causes disorders. Approximately, 300 million people are living with acute or chronic HBV-infections worldwide, and only a fraction of them have access to medical care. The sub-Saharan African (SSA) regions house around 80 million of reported infection cases, and certain SSA-groups like pregnant women and drug-addict are among the most vulnerable. In as much as there is insufficient national data on young adult groups, this study aims to determine HBV-prevalence and associated

Syndromic and biological screening for sexually transmitted infections in female sex workers in Côte d'Ivoire: the ANRS 12381 PRINCESSE cohort study.

BACKGROUND: Female sex workers (FSWs) are at high risk of contracting STIs, in particular in Sub-Saharan Africa. The implementation of oral HIV pre-exposure prophylaxis provided an opportunity to draw attention to the sexual health needs of FSWs. Innovative strategies to screen for and reduce the burden of STIs is thus a priority. This study describes STI screening among FSWs enrolled in the PRINCESSE project in Côte d'Ivoire. METHODS: The PRINCESSE project (2019-2023) was an interventional cohort of FSWs ≥18 years, evaluating a comprehensive, community-based sexual and reproductive health ca

Association of sexual perceptions, behavior, and intimate partner violence with sexually transmitted infection (STI) among Filipino women.

BACKGROUND: Sexually transmitted infections (STI) remain prevalent in the Philippines despite being both preventable and treatable. Women are particularly vulnerable when less prioritized than high-risk groups and unable to speak up in abusive intimate relationships. Although studies on behavior and STI have been conducted, they vary by culture and region, highlighting the importance of representative studies. This study aimed to identify sexual perceptions and practices, and intimate partner dynamics associated with STI in Filipino women. METHODS: A secondary analysis of the 2022 Philippine

Guided internet-based LGBTQ-affirmative cognitive-behavioral therapy: A randomized controlled trial among sexual minority men in China.

OBJECTIVE: LGBTQ-affirmative cognitive-behavioral therapy (CBT) addresses minority stress to improve sexual minority individuals' mental and behavioral health. This treatment has never been tested in high-stigma contexts like China using online delivery. METHOD: Chinese young sexual minority men (n = 120; ages 16-30; HIV-negative; reporting depression and/or anxiety symptoms and past-90-day HIV-transmission-risk behavior), were randomized to receive 10 sessions of culturally adapted asynchronous LGBTQ-affirmative internet-based CBT (ICBT) or weekly assessments only. The primary outcome includ

Mediation of Psychological Capital in Youth Experiencing Homelessness.

BACKGROUND: Youth who experience homelessness engage in behaviors that place them at high risk for disease and injury. Despite their health risk behaviors, these youth display psychological capital, positive attributes of hope, efficacy, resilience, and optimism that motivate them to engage in health-promoting behaviors such as safer sex. However, this array of positive psychological attributes has not been studied in this vulnerable population. OBJECTIVES: The specific aim of this analysis was to determine whether factors of psychological capital mediated the relationship between background

Predictors of maternal HIV acquisition during pregnancy and lactation in sub-Saharan Africa: A systematic review and narrative synthesis.

OBJECTIVES: To eliminate vertical transmission of HIV, global institutions recommend using a risk-guided approach for HIV prevention services in antenatal and postnatal settings. Identifying predictors of maternal HIV acquisition can inform the development of risk-guided approaches, but individual studies of predictors can have limited power and generalizability. METHODS: We conducted a systematic review and narrative synthesis to identify common predictors of maternal HIV acquisition in sub-Saharan Africa (SSA). We searched four databases for full-text articles that estimated associations be

Social norms that sustain transactional sex and associations with sexual health outcomes: A mixed-methods study in the Comarca Ngäbe-Buglé, a rural-Indigenous region of Panama.

The Comarca Ngäbe-Buglé (CNB), home to >200,000 Indigenous people, is one of the poorest regions in Panama. We describe transactional sex (TS) behaviours, normative beliefs and factors associated with TS among Indigenous adolescents(14-19years) in the CNB. We conducted a mixed-methods study in the CNB between January and November 2018, which included a qualitative study with participant observation and semi-structured interviews that focused on descriptive norms related to TS; and a cross-sectional study among public-school-going adolescents using self-administered questionnaire to report sexu
