BackgroundInternet-accessed sexually transmitted infection testing (e-STI testing) is increasingly available as an alternative to testing in clinics. Typically this testing modality enables users to order a test kit from a virtual service (via a website or app), collect their own samples, return test samples to a laboratory, and be notified of their results by short message service (SMS) or telephone. e-STI testing is assumed to increase access to testing in comparison with face-to-face services, but the evidence is unclear. We conducted a randomised controlled trial to assess the effectiveness of an e-STI testing and results service (chlamydia, gonorrhoea, HIV, and syphilis) on STI testing uptake and STI cases diagnosed.Methods and findingsThe study took place in the London boroughs of Lambeth and Southwark. Between 24 November 2014 and 31 August 2015, we recruited 2,072 participants, aged 16–30 years, who were resident in these boroughs, had at least 1 sexual partner in the last 12 months, stated willingness to take an STI test, and had access to the internet. Those unable to provide consent and unable to read English were excluded. Participants were randomly allocated to receive 1 text message with the web link of an e-STI testing and results service (intervention group) or to receive 1 text message with the web link of a bespoke website listing the locations, contact details, and websites of 7 local sexual health clinics (control group). Participants were free to use any other services or interventions during the study period. The primary outcomes were self-reported STI testing at 6 weeks, verified by patient record checks, and self-reported STI diagnosis at 6 weeks, verified by patient record checks. Secondary outcomes were the proportion of participants prescribed treatment for an STI, time from randomisation to completion of an STI test, and time from randomisation to treatment of an STI. Participants were sent a £10 cash incentive on submission of self-reported data. We completed all follow-up, including patient record checks, by 17 June 2016. Uptake of STI testing was increased in the intervention group at 6 weeks (50.0% versus 26.6%, relative risk [RR] 1.87, 95% CI 1.63 to 2.15, P < 0.001). The proportion of participants diagnosed was 2.8% in the intervention group versus 1.4% in the control group (RR 2.10, 95% CI 0.94 to 4.70, P = 0.079). No evidence of heterogeneity was observed for any of the pre-specified subgroup analyses. The proportion of participants treated was 1.1% in the intervention group versus 0.7% in the control group (RR 1.72, 95% CI 0.71 to 4.16, P = 0.231). Time to test, was shorter in the intervention group compared to the control group (28.8 days versus 36.5 days, P < 0.001, test for difference in restricted mean survival time [RMST]), but no differences were observed for time to treatment (83.2 days versus 83.5 days, P = 0.51, test for difference in RMST). We were unable to recruit the planned 3,000 participants and therefore lacked power for the analyses of STI diagnoses and STI ca...

Objective: To assess the effectiveness of a text message result service within an inner London sexual health clinic. Method: Demographic data, diagnoses, and time to diagnosis and treatment were collected over a 6 month period for patients receiving text messages and a matched standard recall group. Data on messages sent, staff time, and cost in relation to result provision were collected. Results: Over a 6 month period 952 text messages were sent. In the final month of analysis, 33.9% of all clinic results were provided by text, resulting in a saving of 46 hours of staff time per month. 49 messages requested that the patient return for treatment, 28 of these patients had untreated genital Chlamydia trachomatis (CT) infection. The mean number of days (SD) to diagnosis was significantly shorter in the text message group (TG) v the standard recall group (SG) (7.9 (3.6) v 11.2 (4.7), p ,0.001). The median time to treatment was 8.5 days (range 4-27 days) for the TG group v 15.0 (range 7-35) for SG, p = 0.005. Conclusion: Patients with genital CT infection are diagnosed and receive treatment sooner since the introduction of a text message result service. The introduction of this service has resulted in a significant saving in staff time.I n genitourinary medicine (GUM) clinics a significant proportion of staff time is taken up providing the results of sexual health screens. In a recent cross directorate survey we identified an average of 120 hours per month were required for this purpose.1 In the majority of cases these results are negative.2 Providing this service diverts staff time and resources from seeing new patients and managing patients with diagnosed infections, and increases the waiting time for an appointment and the time patients spend in clinic. It has been shown that extended waiting times adversely impact on first time attendance of young men.

High-voltage-activated (HVA) calcium channel currents (IBa) were recorded from acutely replated cultured dorsal root ganglion (DRG) neurons. IBa was irreversibly inhibited by 56.9 +/- 2.7% by 1 microM omega-conotoxin-GVIA (omega-CTx-GVIA), whereas the 1,4-dihydropyridine antagonist nicardipine was ineffective. The selective gamma-aminobutyric acidB (GABAB) agonist, (-)-baclofen (50 microM), inhibited the HVA IBa by 30.7 +/- 5.4%. Prior application of omega-CTx-GVIA completely occluded inhibition of the HVA IBa by (-)-baclofen, indicating that in this preparation (-)-baclofen inhibits N-type current. To investigate which G protein subtype was involved, cells were replated in the presence of anti-G protein antisera. Under these conditions the antibodies were shown to enter the cells through transient pores created during the replating procedure. Replating DRGs in the presence of anti-G(o) antiserum, raised against the C-terminal decapeptide of the G alpha o subunit, reduced (-)-baclofen inhibition of the HVA IBa, whereas replating DRGs in the presence of the anti-Gi antiserum did not. Using anti-G alpha o antisera (1:2000) and confocal laser microscopy, G alpha o localisation was investigated in both unreplated and replated neurons. G alpha o immunoreactivity was observed at the plasma membrane, neurites, attachment plaques and perinuclear region, and was particularly pronounced at points of cell-to-cell contact. The plasma membrane G alpha o immunoreactivity was completely blocked by preincubation with the immunising G alpha o undecapeptide (1 microgram.ml-1) for 1 h at 37 degrees C. A similar treatment also blocked recognition of G alpha o in brain membranes on immunoblots.(ABSTRACT TRUNCATED AT 250 WORDS)

In recent years, the sexual health of the nation has risen in profile. We face increasing demands and targets, in particular the 48-hour waiting time directive, and as a result clinic access has become a priority. eTriage is a novel, secure, web-based service designed specifically to increase access to our clinics. It has proved a popular booking method, providing access to 10% of all appointments across the Directorate within six months of introduction. KC60 analyses revealed that the majority of users (58%) underwent asymptomatic screening with the remainder having some degree of pathology. There was a greater percentage prevalence of human papilloma virus, chlamydia, non-specific urethritis, gonorrhoea, herpes and trichomonas in the eTriage population when compared with the general clinic population. A notes review illustrated a high degree of concordance between data entered on eTriage registration and clinical review (97%). A patient survey revealed high levels of patient satisfaction with the service. As an adjunct to our existing booking services, eTriage has served to increase patient choice and has proved itself to be a safe, efficient and effective means of improving patient access.

In the 1980s the outlook for patients with the acquired immunodeficiency syndrome (AIDS) and critical illness was poor. Since then several studies of outcome of HIV+ patients on ICU have shown improving prognosis, with anti-retroviral therapy playing a large part. We retrospectively examined intensive care (ICU) admissions in a large HIV unit in London. Between April 2001 and April 2006 43 patients were admitted to the ICU. The mean age of patients was 44 years and 74% were male. Fifty-six percent of admissions were receiving anti-retroviral therapy and 44% had an AIDS defining diagnosis. The median CD4 count was 128 cells/mL and the median APACHE II score was 21. The commonest diagnostic ICU admission category was respiratory disease. This group experienced higher mortality despite slightly lower APACHE II scores, though this did not achieve statistical significance. The follow up period was one year or until April 2007, when data were censored. ICU mortality was 33%, in hospital mortality was 51% and overall mortality at the end of the study period was 67%. Median survival was 1008 days. The CD4 count did not predict long-term survival, although the sample size was too small for this to be conclusive.

BackgroundOnly governments sensitive to the demands of their citizens appropriately respond to needs of their nation. Based on Professor Amartya Sen's analysis of the link between famine and democracy, the following null hypothesis was tested: "Human Immunodeficiency Virus (HIV) prevalence is not associated with governance".MethodsGovernance has been divided by a recent World Bank paper into six dimensions. These include Voice and Accountability, Political Stability and Absence of Violence, Government Effectiveness, Regulatory Quality, Rule of Law and the Control of Corruption. The 2002 adult HIV prevalence estimates were obtained from UNAIDS. Additional health and economic variables were collected from multiple sources to illustrate the development needs of countries.ResultsThe null hypothesis was rejected for each dimension of governance for all 149 countries with UNAIDS HIV prevalence estimates. When these nations were divided into three groups, the median (range) HIV prevalence estimates remained constant at 0.7% (0.05 – 33.7%) and 0.75% (0.05% – 33.4%) for the lower and middle mean governance groups respectively despite improvements in other health and economic indices. The median HIV prevalence estimates in the higher mean governance group was 0.2% (0.05 – 38.8%).ConclusionHIV prevalence is significantly associated with poor governance. International public health programs need to address societal structures in order to create strong foundations upon which effective healthcare interventions can be implemented.

Our objective was to estimate Chlamydia trachomatis (CT) genital infection point prevalence in young male inmates using a non-invasive sampling technique. All new inmates were invited into the study that consisted of a questionnaire and the provision of a urine sample for analysis. The questionnaire asked about personal characteristics, sexual history and symptoms. CT was diagnosed using nucleic acid amplification tests. In all, 13% of new inmates were found to have CT infection. One-fifth of these CT-positive individuals had symptoms of urethral infection. CT prevalence among young male inmates is comparable with results obtained from young women in UK screening programmes. Numerous factors support the integration of CT screening in prisons into the national chlamydia screening programme.

A national audit of screening of asymptomatic patients seen in UK genitourinary medicine clinics in 2009 was conducted against the national guidelines. Data were aggregated by regions and clinics in regions, allowing practice to be compared within and between regions, as well as to national averages and against national guidelines. The case-notes of 4428 patients were audited. Performance was over 80% against the national guidelines for screening of asymptomatic heterosexual men, men who have sex with men (MSM) and women for chlamydial, gonorrhoeal, syphilis and HIV infections. However, the recommended method of endocervical culture for gonorrhoea was performed in only 65% of women, with a further one-quarter being screened with endocervical or vulvovaginal nucleic acid amplification tests (NAATs). Although significant NAAT use for gonorrhoea was seen in all groups, testing for gonorrhoea by culture is still recommended as a first-line test on invasive samples. Over 80% of MSM, who were not known to be immune, were screened for hepatitis B. Urethral microscopy was performed in 22% of heterosexual men and 17% of MSM, and cervical microscopy in 12% of women.
