Body image and psychosocial well-being in early adolescent development.

Introduction: Body dissatisfaction is a determining factor in defining psychosocial well being in early adolescence. During this period, young people progressively redefine their aesthetic standards. This new body concept influences how girls evaluate and accept their own appearance and is related to the psychophysical changes they undergo during this developmental phase. The aim of this study is to investigate how this change in body image evolves in a sample of early adolescent girls. Sample: The sample was composed of 2,408 early adolescent females from the Veneto region, subdivided into three age groups (761 11-year-olds, 734 13-year-olds, and 913 15-year-olds). Results: Correspondence analysis reveals how, in the 11-years-old group, feeling unattractive is only related to being overweight; this relation, however changes with increases age, when feeling unattractive is not anymore a synonymous of being overweight, and a new association can be observed in older girls who feel underweight and perceive themselves as attractive. Conclusion: Body image components change considerably during the early adolescence transition

Field evaluation of two point-of-care tests for syphilis among men who have sex with men, Verona, Italy

Objectives: The incidence of HIV and syphilis among men who have sex with men (MSM) in Europe has recently increased. Rapid point-of-care tests (POCTs) for syphilis can improve access to screening. The purpose of this study was to evaluate the performance of two syphilis POCTs compared with laboratory tests among MSM. Methods: The study was undertaken in Verona, Italy. Asymptomatic MSM, potentially exposed to syphilis, were enrolled prospectively. The POCTs evaluated were SD Bioline Syphilis 3.0 and Chembio DPP Syphilis Screen & Confirm Assay on both serum and fingerprick blood. The results of the POCTs were read by the naked eye by two independent readers and their concordance assessed. Results: A total of 289 MSM were enrolled in the study. Based on laboratory tests, 35 MSM (12.1%) were TPPA-positive alone and 16 (5.5%) were both Treponema pallidum particle agglutination test (TPPA) and rapid plasma reagin (RPR)-positive. The specificities of both POCTs were above 99% on both serum and fingerstick blood specimens, while sensitivities varied considerably. The sensitivity of the SD Bioline test was lower on fingerprick blood (51.4% and 54.3%, readers 1 and 2, respectively) compared with that on serum (80.0% and 82.9%). In contrast, the Chembio test exhibited similar sensitivity values for serum and fingerprick samples (57.7% and 64.0% on serum vs 65.4% and 69.2% on fingerprick for the treponemal component; 63.6% on both samples by both readers for the non-treponemal component). The positive predictive value ranged between 100% and 93.9% for the treponemal component of both syphilis POCTs, but was lower (76.3%-100%)%) for the non-treponemal component of the Chembio POCT. The negative predictive value surpassed 90% for both tests on both samples. The agreement between readers was very high (>99%). Conclusion: The diagnostic performance of the syphilis POCTs was lower than expected; however, considering the prevalence of syphilis among MSM, POCTs should be recommended to improve syphilis detection among MSM

The SIALON Project: Report on HIV Prevalence and Risk Behaviour Among MSM in Six European Cities

Data from 23 European countries show that the annual number of HIV diagnoses in men who have sex with men (MSM) increased by 86% between 2000 and 2006. This paper reports the main preliminary results of a bio-behavioural survey in MSM with a specific focus on HIV prevalence and use of United Nations General Assembly Special Session (UNGASS) indicators in six cities in Southern and Eastern Europe. Time-location sampling (TLS) was used. A total number of 2,356 questionnaires and 2,241 oral fluid samples were collected (invalid samples 4.1%). The data show different socio-demographic patterns across countries regarding age, level of education, living conditions, living area and self-identity. Southern European cities had the highest percentage of people who had tested for HIV and collected the result. More than 50% of respondents in the sample from Barcelona reported having used a condom last time they had anal sex (57.2%), whilst in all other cities this proportion was below 50%. The cities with the highest HIV prevalence in MSM were Barcelona (17.0%) and Verona (11.8%) whilst lower percentages were reported in Bratislava (6.1%), Bucharest (4.6%), Ljubljana (5.1%) and Prague (2.6%). The low prevalence in Eastern European cities is encouraging. However, with the level of high-risk sexual behaviour documented and the lower frequency of HIV test seeking behaviour, there is a clear risk of an increase in HIV transmission

Changes in the prevalence of self-reported sexually transmitted bacterial infections from 2010 and 2017 in two large European samples of men having sex with men-is it time to re-evaluate STI-screening as a control strategy?

BACKGROUND/OBJECTIVES: Many European countries reported increased numbers of syphilis, gonorrhoea and chlamydia diagnoses among men who have sex with men (MSM) in recent years. Behaviour changes and increased testing are thought to drive these increases. METHODS: In 2010 and 2017, two large online surveys for MSM in Europe (EMIS-2010, EMIS-2017) collected self-reported data on STI diagnoses in the previous 12 months, diagnostic procedures, STI symptoms when testing, number of sexual partners, and sexual behaviours such as condom use during the last intercourse with a non-steady partner in 46 European countries. Multivariate regression models were used to analyse factors associated with diagnoses of syphilis, gonorrhoea/chlamydia, and respective diagnoses classified as symptomatic and asymptomatic. If applicable, they included country-level screening rates. RESULTS: Questions on STI diagnoses and sexual behaviours were answered by 156,018 (2010) and 125,837 (2017) participants. Between 2010 and 2017, overall diagnoses with gonorrhoea/chlamydia and syphilis increased by 76% and 83% across countries. Increases were more pronounced for asymptomatic compared to symptomatic infections. The proportion of respondents screened and the frequency of screening grew considerably. Condomless anal intercourse with the last non-steady partner rose by 62%; self-reported partner numbers grew. Increased syphilis diagnoses were largely explained by behavioural changes (including more frequent screening). Gonorrhoea/chlamydia increases were mainly explained by more screening and a change in testing performance. A country variable representing the proportion of men screened for asymptomatic infection was positively associated with reporting symptomatic gonorrhoea/chlamydia, but not syphilis. DISCUSSION/CONCLUSION: The positive association of country-level screening rates with the proportion of symptomatic infections with gonorrhoea/chlamydia may indicate a paradoxical effect of screening on incidence of symptomatic infections. Treatment of asymptomatic men might render them more susceptible to new infections, while spontaneous clearance may result in reduced susceptibility. Before expanding screening programmes, evidence of the effects of screening and treatment is warranted

Co-producing knowledge of lesbian, gay, bisexual, trans and intersex (LGBTI) health-care inequalities via rapid reviews of grey literature in 27 EU Member States

The health inequalities experienced by lesbian, gay, bisexual, trans and intersex (LGBTI) people are well documented with several reviews of global research summarizing key inequalities. These reviews also show how the health-care needs of LGBTI people are often poorly understood whilst suggesting that targeted initiatives to reduce inequalities should involve LGBTI people

A multi-country comparative study of two treponemal tests for the serodiagnosis of Syphilis amongst Men Who Have Sex with Men (MSM):Chemo-luminescent assay vs Treponema pallidum particle agglutination assay

Introduction:International guidelines recommend routine screening for syphilis amongst keypopulations and vulnerable populations using tests detecting treponemal and nontreponemalantibodies. Whilst treponemal tests have high sensitivities and specificities,they differ regarding subjective or objective interpretation, throughput and workload.CLIAs are cost- and time-effective automated methods for detecting treponemalantibodies. The TPPA has been considered the “gold standard” treponemal assay,however, this includes a highly manual procedure, low throughput and subjectiveinterpretation. The present multi-country study evaluated the ADVIA Centaur® SyphilisCLIA assay compared to the reference SERODIA-TP·PA® for the serodiagnosis ofsyphilis amongst MSM.Method:1,485 MSM were enrolled in Brighton (UK), Malta, and Verona (Italy) as part of a largerWHO multi-country and multi-site ProSPeRo study. Serum was tested with the CLIAassay and TP·PA, in accordance with the manufacturers’ instructions, for a first roundof validation. A second round of validation was carried out for discrepant results thatwere additionally tested with both Western Blot and an Immunoblot.Sensitivity, specificity, positive and negative predictive value (PPV and NPV), likelihoodratios (positive/negative), and the Diagnostic Odds Ratio (DOR)/pre-post-testprobability were calculated.Results:Out of 1,485 eligible samples analysed in the first phase, the SERODIATP·PA identified 360 positive and 1,125 negative cases. The CLIA assay identified 366positives, missclassifying one TPPA-positive sample. In the second phase, the CLIAresulted in 1 false negative and 4 false positive results. Considering the syphilis studyprevalence of 24% (95% CI: 22-26.7), The sensitivity of the ADVIA Centaur® SyphilisCLIA assay was 99.7% (95% CI: 98.5-100), and the specificity was 99.4% (95% CI:98.7-99.7). The ROC area values were 0.996 (95% CI: 0.992-0.999), and both the PPVand NPV values were above 98%Conclusions:The CLIA assay showed similar performance compared to the SERODIA-TP·PA.Considering the study is based on QUADAS principles and with a homogeneouspopulation, results are also likely to be generalisable to MSM population but potentiallynot applicable to lower prevalence populations routinely screened for syphilis. Theautomated CLIA treponemal assay confirmed to be accurate and appropriate forroutine initial syphilis screening, i.e. when the reverse testing algorithm is applied
