Lights, camera research! Short film and social media to recruit to HIV research in Indonesia.

Introduction: HIV prevalence among men who have sex with men has increased in Indonesia, amid reports of growing stigma against lesbian, gay, bisexual and transgender individuals and policies that have pushed back public health outreach to these groups. Methods: We assessed the utility of tailored short film and targeted social media engagement to recruit men who have sex with men in Indonesia to HIV social science research. A short HIV testing promotion film, anonymised short survey and invite to a wider research study was embedded on a website platform and disseminated using geo and social/community group targeting for 1 month via a social networking app and social media platforms. Results: From 3 January 2021 to 3 February 2021, there were over 2200 hits of the website within Indonesia. A total of 177 male web users who identified as men who have sex with men or preferred not to declare their sexuality, engaged by watching the short film and completing the survey, they were aged between 17 and 60 years old, of Indonesian nationality and living in Indonesia. Of these, 88% indicated having at least one HIV test in their lifetime, 66% had felt shame with respect to their sexuality and 53% indicated feeling afraid to have a HIV test. Ninety (51%) of the 177 validated using their email or mobile phone number demonstrating willingness to be contacted to join a further study. Twenty-three eligible men who have sex with men, aged 21-55 years old, joined a further social science research study. Participants were from diverse backgrounds and included men born in provinces outside Bali, of different socio-economic and employment backgrounds and diverse relationship contexts. Discussion: Engaging, empowering digital media involving key health messaging can provide health education in more effective ways, build trust and bring communities together. Targeted digital and social media approaches could reach increasingly marginalised and vulnerable communities to promote individual and public health and enable recruitment to valuable medical research.

Post-exposure prophylaxis in the era of pre-exposure prophylaxis.

OBJECTIVES: 56 Dean Street (56DS), a sexual health clinic in London, provides a quarter of England's HIV post-exposure prophylaxis following sexual exposure (PEPSE). Since the limited introduction of pre-exposure prophylaxis (PrEP) in 2015, PEPSE demand has fallen. METHODS: We performed a case-note review of individuals who received PEPSE at 56DS in August 2018. RESULTS: Two hundred and forty three PEPSE were given; 97% (236) fitted recommended indications according to UK national guidance. Twenty-eight (12%) had documented prior PrEP use; the most common reason for not taking PrEP was lack of supply (15/28; 54%). Up to 1st April 2020, of 215 who had not previously used PrEP, 106 (49%) re-attended 56DS for PrEP initiation. CONCLUSIONS: At 56DS, PEPSE is appropriately given for high-risk HIV exposures. For those who use PrEP, It is important to support their adherence and ensure adequate supply. As PrEP uptake increases, the need for PEPSE may decrease.

Rapid initiation of antiretroviral therapy in those with newly diagnosed HIV infection in London, UK.

OBJECTIVES: In July 2016, as a result of patient demand, we introduced a rapid initiation option (RIO) to offer a first medical appointment and antiretroviral therapy (ART) initiation within 2 days of HIV diagnosis at 56 Dean Street (56DS) , a combined sexual health and HIV treatment service in London, UK. METHODS: We performed a retrospective case-note review of patients newly diagnosed with HIV infection at 56DS following the introduction of the new RIO from July to October 2016. In order to assess the effect of the new service on ART uptake, we chose a comparison group of newly diagnosed patients at 56DS from 1 year earlier: July to October 2015. RESULTS: In the 4 months following RIO introduction, there was a reduction in the median time from HIV diagnosis to the first medical appointment (7 versus 15 days; P < 0.00001) and to ART initiation (8 versus 21 days; P < 0.00001) compared with the same 4-month period 1 year previously. Uptake of ART at first appointment also significantly increased from 60% to 76% (P = 0.0074). CONCLUSIONS: By increasing our clinic capacity and awareness of staff and patients of the RIO service, we were able to fulfil the aim of the service to offer ART more quickly following HIV diagnosis.

A 30-Min Nucleic Acid Amplification Point-of-Care Test for Genital Chlamydia trachomatis Infection in Women: A Prospective, Multi-center Study of Diagnostic Accuracy.

BACKGROUND: Rapid Point-Of-Care Tests for Chlamydia trachomatis (CT) may reduce onward transmission and reproductive sexual health (RSH) sequelae by reducing turnaround times between diagnosis and treatment. The io® single module system (Atlas Genetics Ltd.) runs clinical samples through a nucleic acid amplification test (NAAT)-based CT cartridge, delivering results in 30min. METHODS: Prospective diagnostic accuracy study of the io® CT-assay in four UK Genito-Urinary Medicine (GUM)/RSH clinics on additional-to-routine self-collected vulvovaginal swabs. Samples were tested "fresh" within 10days of collection, or "frozen" at -80°C for later testing. Participant characteristics were collected to assess risk factors associated with CT infection. RESULTS: CT prevalence was 7.2% (51/709) overall. Sensitivity, specificity, positive and negative predictive values of the io® CT assay were, respectively, 96.1% (95% Confidence Interval (CI): 86.5-99.5), 97.7% (95%CI: 96.3-98.7), 76.6% (95%CI: 64.3-86.2) and 99.7% (95%CI: 98.9-100). The only risk factor associated with CT infection was being a sexual contact of an individual with CT. CONCLUSIONS: The io® CT-assay is a 30-min, fully automated, high-performing NAAT currently CE-marked for CT diagnosis in women, making it a highly promising diagnostic to enable specific treatment, initiation of partner notification and appropriately intensive health promotion at the point of care.

InterPrEP: internet-based pre-exposure prophylaxis with generic tenofovir disoproxil fumarate/emtrictabine in London - analysis of pharmacokinetics, safety and outcomes.

OBJECTIVES: The National Health Service in England (NHS England) does not provide pre-exposure prophylaxis (PrEP) against HIV, forcing people to purchase generic versions on the internet. However, there are concerns about the authenticity of medicines purchased online. We established an innovative service offering plasma tenofovir (TFV) and emcitrabine (FTC) therapeutic drug monitoring for people buying generic PrEP online, to ensure that drug concentrations in vivo were consistent with those of propriety brands and previously published data. METHODS: TFV/FTC concentrations were measured by ultra-performance liquid chromatography ultraviolet detection. Evaluation of renal function and testing for HIV, hepatitis B virus (HBV) and hepatitis C virus (HCV) were also carried out, at baseline and every 3-6 months, with risk reduction advice. RESULTS: A total of 293 individuals presented having purchased PrEP on the internet: 85% were white, 84% were taking daily PrEP, and 16% were event-driven. Most were on generic TFV disoproxil fumarate (TDF)/FTC from Cipla Ltd. Median (range) TFV and FTC plasma concentrations were 104 (21-597) ng/mL and 140 (17-1876) ng/mL, respectively. All concentrations were above our established plasma TFV and FTC targets, based on previously published data. Renal function was normal in all evaluable individuals and no new cases of HIV, HBV or HCV infection were seen. CONCLUSIONS: In a population at high risk of HIV acquisition, who cannot yet access PrEP on the NHS, concentrations of TFV and FTC in generic formulations purchased over the internet were similar to (or slightly higher than) those measured in phase I studies with the original formulation from Gilead (Truvada™), which has demonstrated high levels of protection against HIV infection in previous PrEP clinical trials.

High HIV incidence in men who have sex with men attending for postexposure prophylaxis: a service evaluation.

BACKGROUND/AIMS: There are limited outcome data for men who have sex with men (MSM) who have received HIV postexposure prophylaxis (PEP). The objective of this service evaluation was to determine HIV incidence and repeat PEP use among MSM PEP recipients in London, UK. METHODS: Retrospective electronic case-note review of all MSM who were prescribed PEP between January and April 2013 at a central London sexual health service. RESULTS: 530 MSM received PEP between 1 January and 30 June 2013. Of these, 449 had more than 30 days subsequent follow-up at our service. Median age was 31 years. PEP indication was unprotected anal intercourse, 98% (receptive 88% and insertive 10%) and other, 2%. Up to 1 November 2015, total follow-up was 756 person-years. 183 users received repeat PEP. The total number of repeat PEP courses was 442. 57 MSM newly acquired HIV: the HIV incidence was 7.6 per 100 person-years. CONCLUSIONS: PEP was associated with a high risk of subsequent HIV seroconversion in this cohort; this group may be appropriate candidates for pre-exposure prophylaxis.

Is PEP prescribed appropriately?

We describe the characteristics of HIV post-exposure prophylaxis (PEP) recipients and PEP indications at 56 Dean Street, a central London sexual health clinic. PEP was prescribed on 577 occasions. Most (97%) was given for unprotected anal intercourse. Over a fifth of exposures involved recreational drug use. Of the patients prescribed PEP, 5.9% were given PEP more than once in this period. As a snapshot of HIV risk behaviour, we note the prevalence of drug use, sex without condom use and group sex among PEP recipients.

Distinct Urban Mines: Exploiting secondary resources in unique anthropogenic spaces.

Fear of scarcity of resources highlight the need to exploit secondary materials from urban mines in the anthroposphere. Analogous to primary mines rich in one type of material (e.g. copper, gold, etc.), some urban mines are unique/distinct. We introduce, illustrate and discuss the concept of Distinct Urban Mines (DUM). Using the example of a university DUM in the UK, analogous to a primary mine, we illustrate potential product/material yields in respect of size, concentration and spatial location of the mine. Product ownership and replacement cycles for 17 high-value electrical and electronic equipment (EEE) among students showed that 20 tonnes of valuable e-waste were in stockpile in this DUM and a further 87 tonnes would 'soon' be available for exploitation. We address the opportunities and challenges of exploiting DUMs and conclude that they are readily available reservoirs for resource recovery. Two original contributions arise from this work: (i) a novel approach to urban mining with a potential for maximising resource recovery within the anthroposphere is conceptualised; and (ii) previously unavailable data for high-value products for a typical university DUM are presented and analysed.

Does dropping day 5 PEP follow-up affect outcomes? An audit of HIV post-exposure prophylaxis at a central London sexual health clinic.

UK post-exposure prophylaxis (PEP) guidelines were updated by the British Association for Sexual Health and HIV (BASHH) in 2011. In 2013, we changed policy to omit day 5 PEP follow-up at 56 Dean Street as it was felt clinically unnecessary. This audit compares our performance against BASHH standards for PEP attenders during June 2012 and June 2013. We identified 162 PEP prescriptions; PEP assessment and appropriate sexually transmitted infection testing was done well. PEP completion rates and post-PEP HIV testing were lower than BASHH standards. Following omission of day 5 review, documentation that results have been checked was poor; however, attendance at follow-up was not adversely affected.

Avascular necrosis in HIV patients: a case-control study.

This study investigates the association of avascular necrosis (AVN) in human immunodeficiency virus (HIV)-positive individuals with possible risk factors, including antiretroviral therapy. Clinic records of all AVN cases diagnosed up to July 2009 in HIV-positive patients attending North Middlesex Hospital, London, UK were retrospectively reviewed. For each case, one control was randomly selected, matched for gender, age, nadir CD4 count and date of HIV diagnosis. Of 15 symptomatic AVN cases identified, eight were in women. Univariate analysis demonstrated significant associations between AVN and a history of systemic steroid use (p = 0.004) and cumulative exposure to protease inhibitor (p = 0.03). Physicians should be aware of the risk of AVN with steroid use, the importance of early diagnosis and avoidance of other risk factors in order to prevent further joint involvement if possible.

Blood glucose and risk of cardiovascular disease in the Asia Pacific region.

OBJECTIVE: To assess the shape and strength of the association between usual blood glucose and cardiovascular disease (CVD) in Asian and Australasian cohorts and to determine the impact of adjusting for other determinants of CVD risk and excluding people with diabetes. RESEARCH DESIGN AND METHODS: Relative risk estimates and 95% CIs were calculated from Cox models, stratified by sex and cohort, and adjusted for age at risk on individual participant data from 17 cohort studies. Repeat measurements of blood glucose were used to adjust for regression dilution bias. RESULTS: Fasting blood glucose data were available for 237,468 participants, and during approximately 1.2 million person-years of follow-up, there were 1,661 stroke and 816 ischemic heart disease (IHD) events. Data were also available on 27,996 participants with nonfasting glucose measurements. Continuous positive associations were demonstrated between usual fasting glucose and the risks of CVD down to at least 4.9 mmol/l. Overall, each 1 mmol/l lower usual fasting glucose was associated with a 21% (95% CI 18-24%) lower risk of total stroke and a 23% (19-27%) lower risk of total IHD. The associations were similar in men and women, across age-groups, and in Asian compared with Australasian (Australia and New Zealand) populations. Adjusting for potential confounders or removing those with diabetes as baseline did not substantially affect the associations. Associations for nonfasting glucose were weaker than those with fasting glucose. CONCLUSIONS: Fasting blood glucose is an important determinant of CVD burden, with considerable potential benefit of usual blood glucose lowering down to levels of at least 4.9 mmol/l.

Serum triglycerides as a risk factor for cardiovascular diseases in the Asia-Pacific region.

BACKGROUND: The importance of serum triglyceride levels as a risk factor for cardiovascular diseases is uncertain. METHODS AND RESULTS: We performed an individual participant data meta-analysis of prospective studies conducted in the Asia-Pacific region. Cox models were applied to the combined data from 26 studies to estimate the overall and region-, sex-, and age-specific hazard ratios for major cardiovascular diseases by fifths of triglyceride values. During 796,671 person-years of follow-up among 96,224 individuals, 670 and 667 deaths as a result of coronary heart disease (CHD) and stroke, respectively, were recorded. After adjustment for major cardiovascular risk factors, participants grouped in the highest fifth of triglyceride levels had a 70% (95% CI, 47 to 96) greater risk of CHD death, an 80% (95% CI, 49 to 119) higher risk of fatal or nonfatal CHD, and a 50% (95% CI, 29% to 76%) increased risk of fatal or nonfatal stroke compared with those belonging to the lowest fifth. The association between triglycerides and CHD death was similar across subgroups defined by ethnicity, age, and sex. CONCLUSIONS: Serum triglycerides are an important and independent predictor of CHD and stroke risk in the Asia-Pacific region. These results may have clinical implications for cardiovascular risk prediction and the use of lipid-lowering therapy.
