OBJECTIVE To determine the prevalence of rectal chlamydia infection in a cohort of men who have sex with men (MSM) and the proportion of infection that would be missed without routine screening. METHODS MSM presenting to four HIV/GUM outpatient clinics at the Chelsea & Westminster Hospital NHS Foundation Trust between 1 November 2005 and 29 September 2006(More)
OBJECTIVES To investigate the drivers behind the epidemic expansion of lymphogranuloma venereum (LGV) cases in late 2009 to help inform infection control. METHODS An epidemic curve of all LGV diagnoses between 2003 and mid-2012 was plotted and divided into the initial detection period, and endemic, growth and hyperendemic phases. Detailed clinical and(More)
OBJECTIVE To investigate factors associated with variations in diagnoses of primary, secondary and early latent syphilis in England and Wales. METHODS Data were derived from two sources: diagnoses made in genitourinary medicine clinics reported on form KC60, and information collected through National Enhanced Syphilis Surveillance (NESS). Multinomial(More)
OBJECTIVE To determine the prevalence of lymphogranuloma venereum (LGV) and non-LGV associated serovars of urethral and rectal Chlamydia trachomatis (CT) infection in men who have sex with men (MSM). DESIGN Multicentre cross-sectional survey. SETTING Four genitourinary medicine clinics in the United Kingdom from 2006-7. SUBJECTS 4825 urethral and 6778(More)
OBJECTIVE Adolescent and young adult (AYA) populations (12-24 years) represent over 40% of new HIV infections globally. Adolescence is sometimes characterized by high-risk sexual behaviour and a lack of engagement with healthcare services that can affect adherence to antiretroviral therapy (ART). Despite adherence to ART being critical in controlling viral(More)
BACKGROUND The risk of acquiring HIV from a single sexual contact varies enormously reflecting biological and behavioural characteristics of both infected and uninfected partners. Accurate information on HIV transmission risk is required to construct evidence-based risk reduction practices for individuals, to direct the provision of prevention strategies at(More)
We report measurements of single-particle inclusive spectra and two-particle azimuthal distributions of charged hadrons at high transverse momentum (high p(T)) in minimum bias and central d+Au collisions at sqrt[s(NN)]=200 GeV. The inclusive yield is enhanced in d+Au collisions relative to binary-scaled p+p collisions, while the two-particle azimuthal(More)
We report high statistics measurements of inclusive charged hadron production in Au+Au and p+p collisions at sqrt[s(NN)]=200 GeV. A large, approximately constant hadron suppression is observed in central Au+Au collisions for 5<p(T)<12 GeV/c. The collision energy dependence of the yields and the centrality and p(T) dependence of the suppression provide(More)
OBJECTIVES To describe changing characteristics of men who sold sex in London between 1994 and 2003. METHODS A baseline survey of 823 male sex workers attending a specialist clinic, plus follow up of 628 men for 1379 person years. RESULTS Men recruited earlier (1994 to 1996) were more likely than those recruited later (2000 to 2003) to be UK born and to(More)
