Association between STI and child sexual exploitation in children under 16 years old attending sexual health clinics in England: findings from a case-control study

OBJECTIVE: Child sexual exploitation (CSE) can be difficult to identify, as there may be few reliable indicators. Although they may be used in decision-making, there is no evidence that STIs are predictors of CSE. We investigated the relationship between STI presentation at sexual health clinics (SHCs) and CSE. METHODS: SHCs with 18 or more children aged 13-15 years old with STI diagnoses in 2012 were identified using the Genitourinary Medicine Clinic Activity Data Set STI Surveillance System. Cases with confirmed bacterial or protozoal STIs were matched by age, gender and clinic with non-STI controls. Lead clinicians were asked to complete an online questionnaire on CSE-related risk factors of cases and controls irrespective of STI presence. Associations between STI outcome and CSE-related risk factors were analysed using conditional logistic regression. RESULTS: Data were provided on 466 children aged 13-15 years old; 414 (89%) were female, 340 (80%) were aged 15, 108 (23%) were aged 14, and 18 (3.9%) were aged 13 years. In matched univariate analysis, an STI diagnosis was significantly associated with 'highly-likely/confirmed' CSE (OR 3.87, p=0.017) and safeguarding concerns (OR 1.94, p=0.022). Evidence of an association between STI diagnosis and 'highly-likely/confirmed' CSE persisted after adjustment for partner numbers and prior clinic attendance (OR 3.85, p=0.053). CONCLUSION: Presentation with bacterial or protozoal STIs in children aged 13-15 years old at SHCs may be considered a potential marker for CSE. It would be prudent to consider CSE, indepth assessment and potential referral for any children under 16 years old presenting with a bacterial or protozoal STI

Sexual behaviour among casual workers in an international nightlife resort: a case control study

BACKGROUND: Young holidaymakers report increased sexual risk-taking abroad, yet little is currently known about the sexual behaviour of those who extend time abroad through casual work. METHODS: Information on sexual behaviour was collected via an anonymous questionnaire administered to British bar and nightclub workers in Ibiza (cases, n = 92) and British people visiting Ibiza for holiday purposes only (controls, n = 868). RESULTS: Four in five (80.5%) cases who arrived in Ibiza without a partner had sex during their stay and of these two thirds (65.5%) had unprotected sex. Cases were more likely to report sexual risk-taking in Ibiza than controls and reported greater numbers of sexual partners prior to their visit. However, they had fewer sexual partners per week of stay. CONCLUSION: Casual workers in bars and nightclubs abroad are a key risk group for sexual health and a potential conduit for the international spread of sexually transmitted infections. While they are an important target group for sexual health promotion, appropriately trained they are also ideally placed to deliver sexual health interventions to other young travellers

Women's colposcopy experience and preferences: a mixed methods study

<p>Abstract</p> <p>Background</p> <p>The colposcopy service is a key component in the UK Cervical Screening Programme. Over 120,000 women are referred to the service annually, however up to 25% of women fail to attend their appointment. Little is known about patients' preferences for colposcopic investigation and treatment. This study aims to investigate women's experience of colposcopy, to identify patients' preferences for aspects of appointments within the colposcopy service, and to make suggestions for service improvement.</p> <p>Methods/Design</p> <p>This study has been designed as a two stage, mixed method project. Stage one will involve in-depth interviews with new colposcopy patients to ascertain their experience of colposcopy services. This qualitative stage will generate factors thought to be important by service users in their experience. Stage two will utilise a choice based quantitative technique to identify women's preferences and determine the representativeness of factors generated through the interviews.</p> <p>The initial stage of in-depth interviews will be conducted with patients who are newly referred to colposcopy clinics to investigate the experience that they have of the referral process and appointment attendance. The outcome of these interviews will be analysed qualitatively using Framework analysis. Factors found to be important in women's experience will be extracted and used to construct a choice based questionnaire.</p> <p>The discrete choice experiment (questionnaire) will apply a best-worst technique through scenario-based questions to find women's relative preferences for different aspects of the service. It will be offered to women attending follow-up appointments at two colposcopy clinics in the West Midlands. Women will complete the questionnaire whilst they wait for their appointment, or, if they prefer, will take it home to complete in private. Women who do not attend their appointment will be posted the research information and questionnaire. The questionnaire analysis will use a weighted least squares regression technique for each best/worst pair. The accept/reject 'would you attend this appointment' question will be analysed using a random effects logit model.</p> <p>Discussion</p> <p>Colposcopy is a common procedure and one that is associated with raised anxiety among women experiencing the service. Little is known about women's experience of the service or their preferences for service delivery. The outcomes of the study will comprise a description of women's experience of colposcopy and establishing their preferences for how aspects of the service should be provided. Women's preferences will be fed back to service providers to enable improvements to the service to be made.</p

The HIV-1 Subtype C Epidemic in South America Is Linked to the United Kingdom

Background: The global spread of HIV-1 has been accompanied by the emergence of genetically distinct viral strains. Over the past two decades subtype C viruses, which predominate in Southern and Eastern Africa, have spread rapidly throughout parts of South America. Phylogenetic studies indicate that subtype C viruses were introduced to South America through a single founder event that occurred in Southern Brazil. However, the external route via which subtype C viruses spread to the South American continent has remained unclear.Methodology/Principal Findings: We used automated genotyping to screen 8,309 HIV-1 subtype C pol gene sequences sampled within the UK for isolates genetically linked to the subtype C epidemic in South America. Maximum likelihood and Bayesian approaches were used to explore the phylogenetic relationships between 54 sequences identified in this screen, and a set of globally sampled subtype C reference sequences. Phylogenetic trees disclosed a robustly supported relationship between sequences from Brazil, the UK and East Africa. A monophyletic cluster comprised exclusively of sequences from the UK and Brazil was identified and dated to approximately the early 1980s using a Bayesian coalescent-based method. A sub-cluster of 27 sequences isolated from homosexual men of UK origin was also identified and dated to the early 1990s.Conclusions: Phylogenetic, demographic and temporal data support the conclusion that the UK was a crucial staging post in the spread of subtype C from East Africa to South America. This unexpected finding demonstrates the role of diffuse international networks in the global spread of HIV-1 infection, and the utility of globally sampled viral sequence data in revealing these networks. Additionally, we show that subtype C viruses are spreading within the UK amongst men who have sex with men

Adverse outcomes after colposcopy

Abstract Background Colposcopy is an essential part of the National Health Service Cervical Screening Programme (NHSCSP). It is used for both diagnosis and treatment of pre-cancerous cells of the cervix. Despite colposcopy being a commonly performed and relatively invasive procedure, very little research has explored the potential long-term impacts of colposcopic examination upon patient quality of life. The aim of this study is to investigate and quantify any potential reduction in women's quality of life following a colposcopy procedure. More specifically, the degree of female sexual dysfunction and the excess risk of adverse events in those undergoing colposcopy will be explored. If such risks are identified, these can be communicated to women before undergoing colposcopy. It will also assist in identifying whether there are particular sub-groups at greater risk and if so, this may lead to a re-evaluation of current recommendations concerning colposcopically directed treatments. Methods/design Cohort study using postal surveys to assess sexual function and quality of life in women who have attended for colposcopy (cases), compared with those who have not attended colposcopy (controls). The prevalence and excess risk of female sexual dysfunction will be determined. Logistic regression will identify the predictors of adverse outcomes. Discussion There are more than 400,000 colposcopy appointments each year in England, of which 134,000 are new referrals. There is some evidence that there may be long-term implications for women treated under colposcopy with respect to adverse obstetric outcomes, persisting anxiety, increased rates of sexual dysfunction and reduced quality of life. Reliably establishing whether such adverse outcomes exist and the excess risk of adverse events will facilitate informed decision-making and patient choice.</p

A systematic review and meta-analysis of thermal coagulation compared with cryotherapy to treat precancerous cervical lesions in low- and middle-income countries

Background: Thermal coagulation is gaining popularity for treating cervical intraepithelial neoplasia (CIN) in screening programs in low- and middle-income countries (LMICs) due to unavailability of cryotherapy. Objectives: Assess the effectiveness of thermal coagulation for treatment of CIN lesions compared with cryotherapy, with a focus on LMICs. Search strategy: Papers were identified from previous reviews and electronic literature search in February 2018 with publication date after 2010. Selection criteria: Publications with original data evaluating cryotherapy or thermal coagulation with proportion of cure as outcome, assessed by colposcopy, biopsy, cytology, and/or visual inspection with acetic acid (VIA), and minimum 6 months follow-up. Data collection and analysis: Pooled proportions of cure are presented stratified per treatment modality, type of lesion, and region. Main results: Pooled cure proportions for cryotherapy and thermal coagulation, respectively, were 93.8% (95% CI, 88.5–97.7) and 91.4% (95% CI, 84.9–96.4) for CIN 1; 82.6% (95% CI, 77.4–87.3) and 91.6% (95% CI, 88.2–94.5) for CIN 2–3; and 92.8% (95% CI, 85.6–97.7) and 90.1% (95% CI, 87.0–92.8) for VIA-positive lesions. For thermal coagulation of CIN 2–3 lesions in LMICs 82.4% (95% CI, 75.4–88.6). Conclusions: Both cryotherapy and thermal coagulation are effective treatment modalities for CIN lesions in LMICs.Medical Instruments & Bio-Inspired Technolog

Communicating the Benefits and Harms of Cancer Screening

Breast and cervical screening each have a distinct balance of benefits and harms. While they are both likely to reduce mortality, breast screening is associated with a greater relative frequency of serious harms than cervical screening. A unique approach has been adopted in England with respect to providing information on cancer screening with the goal of facilitating informed choice. The new materials provide more detail than previous information about the benefits and harms of screening as well as the scientific uncertainties. While there is a uniform format and the information covers the same key issues in both breast and cervical screening programmes, the emphasis and detail varies according to balance of benefits and harms within these programmes
