Developing acute hepatitis B in immunocompetent non-responders to hepatitis B vaccination has been rarely reported. We report such a case in a 79 year old heterosexual male. There is evidence that tenofovir disoproxil/emtricitabine as primary prophylaxis can prevent acquisition of hepatitis B. In the current era of HIV pre-exposure prophylaxis (PrEP) with tenofovir disoproxil/emtricitabine, there is dual benefit of preventing HIV and hepatitis B. We discuss the importance of considering tenofovir disoproxil/emtricitabine pre-exposure prophylaxis in those hepatitis B vaccination non-responders at high risk of acquiring hepatitis B.

BACKGROUND: The UK pledged commitment to the global strategy of zero new HIV infections and HIV-related deaths by 2030. PrEP was commissioned in England in 2020 and is fundamental to achieving these targets, yet awareness and uptake are suboptimal in certain populations.
METHODS: Sexual Health London (SHL) incorporated questions on its e-triage questionnaire estimating need for PrEP amongst online service users. Two types of signposting messaging were shown to users directing them to more detailed online content: PrEP-discussion (potential need) and PrEP-eligible (assumed need). The effectiveness of this signposting was evaluated by reviewing demographics and triage responses in returning users.
RESULTS: 426,149 SHL users requested STI screening between 1.7.21-31.10.22. 16% (69,867/426,149) and 32.2% (137,489/426,149) of individuals received PrEP-eligible and PrEP-discussion signposting. The PrEP-eligible cohort were: 41.0% gay/bisexual or other men who have sex with men (GBMSM), 16.3% heterosexual males, 33.1% heterosexual females, and 60.6% were of white ethnicity. The PrEP-discussion cohort were: 9.3% GBMSM, 34.3%% heterosexual males, 45.5% heterosexual females and 63.7% of white ethnicity. 50.4% (35,190/69,867) and 41.3% (56,808/137,489) of the PrEP-eligible and PrEP discussion cohorts ordered a subsequent SHL STI testing kit, during which 10.0% (3510/35,190) and 5.9% (3364/56,808) reported taking PrEP. Of those who denied taking PrEP, 59% (18,702/31,680) and 61.0% (32,559/53,444) triggered PrEP signposting again. 95.4% of PrEP starters were GBMSM (6562/6874) and 1.4% (97/6874) heterosexual males/females.
CONCLUSIONS: The e-service demonstrated feasibility in estimating PrEP need and signposting service users. Up to 16% of returning users subsequently commenced PrEP. This highlights significant missed opportunities for the remaining online users, who continue to report HIV acquisition risk(s). Further efforts regionally/nationally to optimise uptake of PrEP, particularly among under-represented groups are warranted.

UNASSIGNED: The unique nature of adolescence makes youths highly susceptible to high-risk behaviours. Thus, prevention and health promotion are imperative for this influential age. Despite various approaches towards health promotion, knowledge related to adolescent health is still low among Malaysian adolescents. This study aims to investigate adolescent health information-seeking behaviours related to high-risk behaviours.
UNASSIGNED: A cross-sectional study was conducted among 370 adolescents aged 10 years old-19 years old throughout Malaysia. The questionnaire used was adapted from a previous study and the pilot study resulted in Cronbach\'s alpha of 0.85. IBM SPSS Statistics version 25.0 software was used for data analysis at two statistical levels: descriptive and inferential (Mann-Whitney U test).
UNASSIGNED: The most important health information needs related to high-risk behaviour according to the adolescents were \'violence\' (3.72 score out of 5), \'sexual activity-related disease\' (3.64 score out of 5) and \'physical activity and effect of lack in physical activity\' (3.61 score out of 5). \'Physician\' (4.01 score out of 5) and \'the internet\' (3.95 score out of 5) were the most important sources for obtaining health information related to high-risk behaviours. The main criterion for the quality of health information was the \'validity and reliability of the information\' (4.55 score out of 5). The findings indicate that adolescents have a positive attitude towards health information-seeking behaviour, although slight differences between boys and girls are exhibited. The most common barrier to health information seeking experienced by adolescents is \'difficulty in determining the quality of information found\'.
UNASSIGNED: Adolescents tend to use professional and informal sources, have good criteria in the selection of information and have a considerably high interest in seeking health information related to high-risk behaviour.

Incidence of sexually transmissible infections (STI) amongst young Aboriginal people in Australia are significantly higher compared to the wider population. Low levels of engagement with public sexual health services also exacerbates health inequity. This study sought to understand the access barriers facing Aboriginal People with local Sexual Health services from the perspective of local clinicians within Western Sydney.
Six clinicians (six registered nurses, two medical practitioners) and two social workers, working in a Sexual Health service, were interviewed using a semi-structure questionnaire. Interviews were audio recorded and transcribed verbatim. Interview texts were analysed using NVIVO 12 and a thematic analysis undertaken.
Thematic analysis revealed three broad themes: personal, practical, and programmatic. Clinicians believed the involvement of Aboriginal people in service delivery would contribute to greater inclusion and more culturally competent services. Clinicians also considered that young Aboriginal people were unaware of the risks of untreated STIs, and that greater STI-related education regarding risk and prevention may reduce STI incidence and improve participation in services. Clinicians believed that culturally-competent STI education would be more effective if co-designed with the local Aboriginal community. Clinicians identified that Aboriginal young people were concerned about their privacy when accessing services, and that barriers could be reduced by greater community engagement in service delivery design and quality improvement initiatives.
The three themes identified in this study provide guidance for service providers about approaches that may enhance the access, participation, and cultural safety sexual health services for Aboriginal clients.

UNASSIGNED: Syphilis is a treatable bacterial infection caused by Treponema pallidum. There has been a change in incidence of syphilis in various nations over the years.
UNASSIGNED: To study the epidemiological trends, demographic profile, high-risk behaviour, clinical pattern, and stage of syphilis over the last ten years in patients presenting to an STD clinic in a tertiary care hospital.
UNASSIGNED: This was a retrospective observational study over ten years. Records of all confirmed syphilis cases were analysed in relation to demography and clinical profile.
UNASSIGNED: There were a total of 3,110 STD patients among whom 31 cases (accounting for 0.99%) of confirmed syphilis were seen. There was a significant increase in cases in the last five years of study, especially in the last year. An increase in primary (PS) and secondary syphilis (SS) was observed. Males outnumbered females (3:1). Mean age of patients was 35.0 ± 11.53 years. Professionals were most common (22.6%) having syphilis followed by farmers (19.35%). A significant proportion (45.1%) of our patients were at least graduates. Unprotected sex was seen in all the patients followed by extramarital/premarital sex (71.35%). There were 16.12% of cases who had a history of paid sex and 9.7% were homosexuals. SS and latent syphilis were more common (38.7% each) than PS (19.35%). In PS single chancre and in SS truncal asymptomatic rash was the commonest clinical presentation. Limitation: Single-centre study, including only self-reported patients leading to a small sample size, is the major limitation of the study.
UNASSIGNED: The increased trend of primary and secondary syphilis in recent years highlights that there is a risk of an impending epidemic.

Alcohol and drug use is overrepresented among individuals living with Human Immunodeficiency Virus (HIV) and is associated with poor health outcomes. Determining the extent to which substance use differs between demographic profiles of people living with HIV (PLWH) would determine at-risk groups that would benefit from intervention.
Cross-sectional screening data (N = 1307, Mage = 42.7 years, 66% male, 86% African American, 39% sexual minority) was examined from an HIV clinic in the southern U.S. largely treating underserved and low-income patients. Age, gender, race/ethnicity, sexual orientation, and their interactions were entered as predictors of substance use and related impairment in a series of zero-inflated negative binomial regressions.
African Americans reported more drug use (p = 0.004) and drug-related negative consequences (p = 0.003). Notably, alcohol-related negative consequences of African American heterosexuals were much higher at younger ages, compared to sexual minorities (regardless of race) and White heterosexuals of all age groups (p = 0.04).
Among PLWH in the U.S. South, African Americans may be uniquely at-risk with for problems related to drug-related functional impairment. Specifically, young heterosexual African Americans are at high risk for alcohol-related impairment. Implications are discussed.

Objective: Syphilis infection remains a significant health issue among marginalised populations in Indonesia, in particular among men who have sex with men (MSM), in whom there are limited studies from Indonesia exploring risk factors associated with STI acquisition.Our study aimed to identify risk factors of syphilis infection among MSM attending large sexual health clinic in Jakarta. Methods: We conducted a retrospective cohort analysis using patient records (MSM aged 18 years or older) period Jan 2018-Dec 2019. We used Cox regression to identify risk factors associated with syphilis incidence. Results: Study population were 2912 MSM tested for syphilis, 473 (16.2%) were diagnosed with syphilis on their first visit; early syphilis (415; 14%) and latent syphilis (58, 2%). Among the cohort of 2439 MSM who tested negative at baseline, 40 MSM were identified with a new positive syphilis result during 2 years follow up. Risk factors remaining significantly associated with syphilis incidence included having STI symptom at 1st visit (aHR, 2.8; 95% CI, 1.38-5.65), and HIV-infection (aHR 4.53; 95% CI 2.24 - 9.17).Syphilis incidence rate was 8.19 (95% CI 6.01-11.16) per 100 PYFU. Conclusions: Syphilis infection at baseline and incidence was high among MSM attending this large clinic in Jakarta. Integrated and accessible syphilis prevention and detection coupled with HIV services are needed, with a special focus on high-risk individuals.

Adolescents frequently engage in high-risk behaviours (HRB) following childhood sexual abuse (CSA). Aberrant reward processes are implicated in HRB, and their underlying fronto-striatal networks are vulnerable to neurodevelopmental changes during adversity representing a promising candidate for understanding links between CSA and HRB. We examined whether fronto-striatal responses during reward anticipation and feedback (i) are altered in depressed adolescents with CSA compared to depressed, non-abused peers and (ii) moderate the relationship between CSA and HRB irrespective of depression. Forty-eight female adolescents {14 with CSA and depression [CSA +  major depressive disorder (MDD)]; 17 with MDD but no CSA (MDD); 17 healthy, non-abused controls} completed a monetary reward task during functional magnetic resonance imaging. No differences in fronto-striatal response to reward emerged between CSA + MDD and MDD. Critically, high left nucleus accumbens activation during reward anticipation was associated with greater HRB in CSA + MDD compared to MDD and controls. Low left putamen activation during reward feedback was associated with the absence of HRB in CSA + MDD compared to MDD. Striatal reward responses appear to play a key role in HRB for adolescents with CSA irrespective of depression, providing initial support for a CSA ecophenotype. Such information is pivotal to identify at-risk youth and prevent HRB in adolescents after CSA.

Background: Although there are several ways to transmit HIV, condomless sex remains the primary mode in sub-Saharan Africa, including South Africa, with KwaZulu-Natal Province being one of the epicentres of HIV infection. This study explored the use of condoms in serodiscordant couples who were exposed to an HIV-risk reduction intervention that aimed to improve condom use and reduce the spread of HIV.Methods: A Total of 30 couples completed a paper-based questionnaire on their demographics and general health at baseline and 3 months, plus a semi-structured questionnaire with four domains. An analysis of HIV knowledge, condom use, condom use attitudes and protection perceptions about how other serodiscordant couples behave was conducted following a 12-week HIV risk reduction intervention. Participants were randomised 2:1 into intervention and control groups.Results: Condom use increased from 55% at baseline to 73.7% (p = .0047) at 3 months for the intervention group and condom use in the last 7 days increased from 53% to 86% (p = .0117). For the control group, condom use remained low at the 3 months follow up period (p = .625). HIV knowledge improved significantly from baseline to 3 months for the intervention group (p < .0001), as well as the control group (p = .0005). Negative HIV condom use attitude scores in both groups decreased significantly from baseline to 3 months; intervention group (p = .0059) and control group (p = .0007).Conclusion: HIV knowledge and condom use improved significantly, while negative condom use attitudes and HIV protection perceptions decreased significantly following exposure to a risk-reduction intervention, suggesting that HIV preventive interventions should focus on partnership interventions.
