RESUMEN

BACKGROUND: In pregnancy, reduction of HIV plasma viral load (pVL) for the prevention of vertical transmission is time-constrained. The study primary objective is to investigate factors associated with faster initial HIV RNA half-life decay when combination antiretroviral treatment (cART) is initiated in pregnancy. METHODS: This was a multicentre, retrospective, observational study, conducted in south England, United Kingdom, between August 2001 and February 2018. Data were extracted from case notes of eligible women initiating cART during the index pregnancy. Anonymised data were collated and analysed centrally. Regression analyses were conducted to determine factors associated with faster HIV RNA half-life decay in the first 14 days after commencing cART (first-phase), and with achieving an undetectable maternal pVL by 36 weeks' gestation. We then assessed whether HIV- and obstetric- related parameters differed by antiretroviral third agent class and whether the proportions of women with undetectable pVL at 36 weeks' gestation and at delivery differed by antiretroviral third agent class. RESULTS: Baseline pVL was the only independent factor associated with faster first-phase HIV RNA half-life decay on commencing cART. Lower pVL on day 14 after starting cART was associated with an increased likelihood of achieving an undetectable pVL by 36 weeks' gestation. Integrase inhibitor-based cART was associated with a faster first-phase HIV RNA half-life decay on commencing cART. Overall, 73% and 85% of women had an undetectable pVL at 36 weeks' gestation and at delivery respectively, with no significant difference by antiretroviral third agent class. CONCLUSIONS: Only high baseline pVL independently contributed to a faster rate of first-phase viral half-life decay. pVL at 14 days after initiating cART allows early identification of treatment failure. In the first 14 days after initiating cART in pregnancy, integrase inhibitor-based cART reduced maternal pVL faster than protease inhibitor- and non-nucleoside reverse transcriptase-based cART. While our study findings support INSTI use when initiated in pregnancy especially when initiated at later gestations and in those with higher baseline pVL, other non-INSTI based cART with more data on safety in pregnancy also performed well.

RESUMEN

Syphilis rates have been increasing in men who have sex with men (MSM) in London. To describe risk behaviour and refine public health interventions, we conducted prospective enhanced surveillance of new syphilis cases in MSM attending selected London sexual health clinics (SHCs) between October 2016 and January 2017. Sexual health advisors (SHAs) completed 107 questionnaires. Eighteen per cent of respondents reported always using condoms, with lower use in HIV-positive (8%, 4/53) than HIV-negative men (33%, 14/52). Almost half of respondents reported condomless sero-discordant sex (46%, 33/72). The most frequent means of meeting new partners reported were venues (80%, 76/95), particularly bars or clubs (34%, 32/95), and apps or websites (79%, 75/95). Nearly a third of respondents reported engaging in group sex (32%, 30/95). Almost half reported drug use during sex (47%, 46/98), with HIV-positive men more likely to report use of the three main 'chemsex' drugs. The majority of respondents preferred health promotion information from SHAs (63%, 58/92) compared to other sources such as Google/Wikipedia and apps. Prevention activity should continue to focus on condomless sex, serosorting, multiple and overlapping partners, and chemsex. SHCs, particularly those serving HIV-positive men, are important sources for sexual health promotion advice.

RESUMEN

PLAIN ENGLISH SUMMARY: There are new ways to engage people with science and research but many patient support groups and charitable organisations still hold traditional meetings to provide updates on their activities and to report new developments in their field of interest. These meetings often feature presentations given by medical doctors or, in the case of research-focussed organisations, by research scientists.Receiving feedback from people who are confused and sometimes upset by some types of information, and the way it is presented at meetings, made us think about better ways for researchers to discuss their ideas for new research, or share the findings from completed projects, with patients and members of the public.This article describes a method of public engagement called "Meet the Researchers" that enables people to hear about current trends in research face to face with the researchers planning or conducting it. "Meet the Researchers" is designed to promote discussion and allow questions to be asked in a relaxed and informal way, in small groups, which is less daunting than asking questions in front of a conference audience. The aim is to break down the barriers between researchers and patients, and enable conversations that will lead to meaningful engagement and a better understanding of research. Additionally we aim to improve understanding of how results are passed on to doctors and nurses and translated into improvements in patient care.The method was tested with patients and was rated very highly by them in the feedback they gave. ABSTRACT: Background Innovative approaches to engaging people with science exist but are often framed around interactive events or social media technologies. Notwithstanding the availability of novel approaches, many patient support groups and charitable organisations continue to hold traditional meetings and seminars to provide information and updates on their activities, and report on developments in their field of interest. In the case of research-focussed organisations, these meetings often take the form of presentations delivered by clinical experts or research scientists.Observation of mesothelioma patients, their relatives, friends and carers attending scientific or clinical-themed meetings has shown that they can be confused, and sometimes distressed, by presentations. This can be due to didactic presentations that are not properly targeted to this audience and a lack of a general overview or summary at the end of meetings that would provide some simple take home messages. This experience motivated the development of a less formal method of sharing complex information and ideas in a simplified manner. "Meet the Researchers" aims to make researchers accessible to patients in order to raise awareness and understanding of research and to explain how research translates into, and informs practice. This approach encourages the use of plain English, removes the tendency to rely on PowerPoint slides to convey the message and moreover, provides an opportunity for researchers to hear patients' views. Methods Small groups of participants met face to face with the researchers planning or conducting research into their condition, and discussed the topics in a relaxed and informal way. The researchers spent a minimum of 20-min with each group before moving on to the next. Info-graphics on a portable device or printed hand-outs in plain English were allowed but no formal presentations were made. Results Our method has been evaluated using feedback data from three annual events held from 2016 to 2018: 100% of participants indicated that they liked the format "very much"(76.0%) or "quite a lot"(24.0%); 80.4% found the topics "very interesting" and 75.9% found it "very easy" to ask questions. Free text comments revealed themes of 'hope' and 'altruism'. Researchers also reported benefits from participation such as learning about patient' priorities and networking. Conclusion "Meet the Researchers" provides a unique opportunity for mesothelioma researchers and patients, relatives and carers to interact on a more equal footing. It stimulates discussion, promotes understanding and provides a more informal setting for non-professional participants to ask questions. It is a format that could easily be adapted for use in other conditions.

RESUMEN

Epididymo-orchitis is a commonly encountered condition with a reported incidence of 2.45 cases per 1000 men in the United Kingdom. This 2016 International Union against Sexually Transmitted Infections guideline provides up-to-date advice on the management of this condition. It describes the aetiology, clinical features and potential complications, as well as presenting diagnostic considerations and clear recommendations for management and follow-up. Early diagnosis and management are essential, as serious complications can include abscess formation, testicular infarction and infertility. Recent epidemiological evidence suggests that selection of fluoroquinolone antibiotics with anti-Chlamydial activity is more appropriate in the management of sexually active men in the over 35 years age group.

RESUMEN

BACKGROUND: Pre-exposure prophylaxis (PrEP) has proven biological efficacy to reduce the sexual acquisition of the human immunodeficiency virus (HIV). The PROUD study found that PrEP conferred higher protection than in placebo-controlled trials, reducing HIV incidence by 86 % in a population with seven-fold higher HIV incidence than expected. We present the baseline characteristics of the PROUD study population and place the findings in the context of national sexual health clinic data. METHODS: The PROUD study was designed to explore the real-world effectiveness of PrEP (tenofovir-emtricitabine) by randomising HIV-negative gay and other men who have sex with men (GMSM) to receive open-label PrEP immediately or after a deferral period of 12 months. At enrolment, participants self-completed two baseline questionnaires collecting information on demographics, sexual behaviour and lifestyle in the last 30 and 90 days. These data were compared to data from HIV-negative GMSM attending sexual health clinics in 2013, collated by Public Health England using the genitourinary medicine clinic activity database (GUMCAD). RESULTS: The median age of participants was 35 (IQR: 29-43). Typically participants were white (81 %), educated at a university level (61 %) and in full-time employment (72 %). Of all participants, 217 (40 %) were born outside the UK. A sexually transmitted infection (STI) was reported to have been diagnosed in the previous 12 months in 330/515 (64 %) and 473/544 (87 %) participants reported ever having being diagnosed with an STI. At enrolment, 47/280 (17 %) participants were diagnosed with an STI. Participants reported a median (IQR) of 10 (5-20) partners in the last 90 days, a median (IQR) of 2 (1-5) were condomless sex acts where the participant was receptive and 2 (1-6) were condomless where the participant was insertive. Post-exposure prophylaxis had been prescribed to 184 (34 %) participants in the past 12 months. The number of STI diagnoses was high compared to those reported in GUMCAD attendees. CONCLUSIONS: The PROUD study population are at substantially higher risk of acquiring HIV infection sexually than the overall population of GMSM attending sexual health clinics in England. These findings contribute to explaining the extraordinary HIV incidence rate during follow-up and demonstrate that, despite broad eligibility criteria, the population interested in PrEP was highly selective.
