RESUMO

Classification images (CIs) measured in a face discrimination task differ significantly between older and younger observers. These age differences are consistent with the hypothesis that older adults sample diagnostic face information less efficiently, or have higher levels of internal noise, compared to younger adults. The current experiments assessed the relative contributions of efficiency and internal noise to age differences in face discrimination using the external noise masking and double-pass response consistency paradigms. Experiment 1 measured discrimination thresholds for faces embedded in several levels of static white noise, and the resulting threshold-vs.-noise curves were used to estimate calculation efficiency and equivalent input noise: older observers had lower efficiency and higher equivalent input noise than younger observers. Experiment 2 presented observers with two identical sequences of faces embedded in static white noise to measure the association between response accuracy and response consistency and estimate the internal:external (i/e) noise ratio for each observer. We found that i/e noise ratios did not differ significantly between groups. These results suggest that age differences in face discrimination are due to differences in calculation efficiency and additive internal noise, but not to age differences in multiplicative internal noise.

RESUMO

Context: Differences of sex development (DSD) represent a wide range of conditions presenting at different ages to various health professionals. Establishing a diagnosis, supporting the family, and developing a management plan are important. Objective: We aimed to better understand the presentation and prevalence of pediatric DSD. Methods: A retrospective, observational cohort study was undertaken in a single tertiary pediatric center of all children and young people (CYP) referred to a DSD multidisciplinary team over 25 years (1995-2019). In total, 607 CYP (520 regional referrals) were included. Data were analyzed for diagnosis, sex-assignment, age and mode of presentation, additional phenotypic features, mortality, and approximate point prevalence. Results: Among the 3 major DSD categories, sex chromosome DSD was diagnosed in 11.2% (68/607) (most commonly 45,X/46,XY mosaicism), 46,XY DSD in 61.1% (371/607) (multiple diagnoses often with associated features), while 46,XX DSD occurred in 27.7% (168/607) (often 21-hydroxylase deficiency). Most children (80.1%) presented as neonates, usually with atypical genitalia, adrenal insufficiency, undescended testes or hernias. Those presenting later had diverse features. Rarely, the diagnosis was made antenatally (3.8%, n = 23) or following incidental karyotyping/family history (n = 14). Mortality was surprisingly high in 46,XY children, usually due to complex associated features (46,XY girls, 8.3%; 46,XY boys, 2.7%). The approximate point prevalence of neonatal referrals for investigation of DSD was 1 in 6347 births, and 1 in 5101 overall throughout childhood. Conclusion: DSD represent a diverse range of conditions that can present at different ages. Pathways for expert diagnosis and management are important to optimize care.

RESUMO

OBJECTIVE: Induction of puberty with exogenous oestrogen results in considerable variability in final uterine and breast volumes. We set out to quantify the variability of these two outcome measures with a view to establishing monitoring methods that could be used to individualise treatment protocols. DESIGN: A prospective observational study. PARTICIPANTS: Sixteen participants with pubertal delay and primary amenorrhoea, due to hypogonadism were recruited from paediatric gynaecology and endocrinology clinics at University College London Hospital. A standardised protocol of transdermal 17ß oestradiol (17ßE) was used (Evorel™), with a starting dose of 12.5 mcg increasing to 25 mcg (patch changed twice weekly) after 4 months. Follow up was every 2 months for a total of 8 months. MEASUREMENTS: Uterine dimensions using ultrasound, oestradiol concentrations and breast development assessed by both Tanner staging and 3D photographic imaging. RESULTS: After 8 months of treatment, the changes in oestradiol concentrations (0-174 pmol), uterine volume growth (4.4-16.4 ml) and breast volume (1.76-140.1 ml) varied greatly between individuals. Of uterine parameters, transverse uterine diameter was most closely associated with serum oestradiol levels at 8 months (beta standardised coefficient = 0.80, p = .001). Change in breast volume was associated with age of treatment initiation (beta standardised coefficient 0.55 p = .04). CONCLUSIONS: We demonstrate variation in response to exogenous oestrogen, emphasising the necessity for individualised dose titration. In the absence of sensitive oestradiol assays, uterine transverse measurements may be used as a surrogate marker of oestrogen sensitivity to guide early dose adjustment. 3D breast imaging may provide a quantitative assessment of breast development to complement Tanner breast staging.

RESUMO

OBJECTIVES: To examine legal and social determinants of violence, anxiety/depression among sex workers. METHODS: A participatory prospective cohort study among women (inclusive of transgender) ≥18 years, selling sex in the last 3 months in London between 2018 and 2019. We used logistic generalised estimating equation models to measure associations between structural factors on recent (6 months) violence from clients or others (local residents, strangers), depression/anxiety (Patient Health Questionnaire-4). RESULTS: 197 sex workers were recruited (96% cisgender-women; 46% street-based; 54% off-street) and 60% completed a follow-up questionnaire. Street-based sex workers experienced greater inequalities compared with off-street in relation to recent violence from clients (73% vs 36%); police (42% vs 7%); intimate partner violence (IPV) (56% vs 18%) and others (67% vs 17%), as well as homelessness (65% vs 7%) and recent law enforcement (87% vs 9%). Prevalence of any STI was 17.5% (17/97). For street-based sex workers, recent arrest was associated with violence from others (adjusted OR (aOR) 2.77; 95% CI 1.11 to 6.94) and displacement by police was associated with client violence (aOR 4.35; 95% CI 1.36 to 13.90). Financial difficulties were also associated with client violence (aOR 4.66; 95% CI 1.64 to 13.24). Disability (aOR 3.85; 95% CI 1.49 to 9.95) and client violence (aOR 2.55; 95% CI 1.10 to 5.91) were associated with anxiety/depression. For off-street sex workers, financial difficulties (aOR 3.66; 95% CI 1.64 to 8.18), unstable residency (aOR 3.19; 95% CI 1.36 to 7.49), IPV (aOR 3.77; 95% CI 1.30 to 11.00) and alcohol/drug use were associated with client violence (aOR 3.16; 95% CI 1.26 to 7.92), while always screening and refusing clients was protective (aOR 0.36; 95% CI 0.15 to 0.87). Disability (aOR 5.83; 95% CI 2.34 to 14.51), unmet mental health needs (aOR 3.08; 95% CI 1.15 to 8.23) and past eviction (aOR 3.99; 95% CI 1.23 to 12.92) were associated with anxiety/depression. CONCLUSIONS: Violence, anxiety/depression are linked to poverty, unstable housing and police enforcement. We need to modify laws to allow sex workers to work safely and increase availability of housing and mental health services.

RESUMO

OBJECTIVES: Describe cases of female genital mutilation (FGM) presenting to consultant paediatricians and sexual assault referral centres (SARCs), including demographics, medical symptoms, examination findings and outcome. DESIGN: The well-established epidemiological surveillance study performed through the British Paediatric Surveillance Unit included FGM on the monthly returns. SETTING: All consultant paediatricians and relevant SARC leads across the UK and Ireland. PATIENTS: Under 16 years old with FGM. INTERVENTIONS: Data on cases from November 2015 to November 2017 and 12 months later meeting the case definition of FGM. MAIN OUTCOME MEASURES: Returns included 146 cases, 103 (71%) had confirmed FGM and 43 (29%) did not meet the case definition. There were none from Northern Ireland. RESULTS: The mean reported age was 3 years. Using the WHO classification of FGM, 58% (n=60) had either type 1 or type 2, 8% (n=8) had type 3 and 21% (n=22) had type 4. 13% (n=13) of the cases were not classified and none had piercings or labiaplasty. The majority, 70% had FGM performed in Africa with others from Europe, Middle East and South-East Asia. There were few physical and mental health symptoms. Only one case resulted in a successful prosecution. CONCLUSIONS: There were low numbers of children presenting with FGM and in the 2 years there was only one prosecution. The findings may be consistent with attitude changes in FGM practising communities and those at risk should be protected and supported by culturally competent national policies.

RESUMO

STUDY OBJECTIVE: Endometriosis is a recognized cause of pelvic pain in adolescents with menstrual symptoms that significantly affect education, activity, and social interactions. We aim to provide an updated systematic review of the prevalence of endometriosis in adolescents with pelvic pain presenting for gynecological investigation. DATA SOURCES: We searched Medline, Embase, and Cinahl from 2011 to July 2019. METHODS OF STUDY SELECTION: We included cohort studies of adolescents with pelvic pain undergoing gynecological investigation. Two authors independently selected studies and extracted study characteristics and prevalence data. Methodological quality was assessed using the Critical Appraisal Skills Program for cohort studies. RESULTS: This updated systematic review evaluated a total of 19 studies including 1243 symptomatic adolescents. In all, 648 of 1011 (64%) adolescents undergoing laparoscopy were found to have endometriosis. The prevalence ranged from 25% to 100%, with a mean prevalence of 64%. Thirteen studies including 381 participants categorized disease severity using the revised American Society of Reproductive Medicine classification. Among these, 53% of participants (201/381) had stage I, 28% (105/381) had stage II, 20% (76/381) had stage III, and 13% (49/381) had stage IV disease. CONCLUSIONS: The prevalence of endometriosis among adolescents with pelvic pain symptoms is high. Endometriosis is treatable, and prompt recognition will help to ensure that adolescents are signposted earlier to appropriate specialists. The management of adolescents with suspected endometriosis should be consistent with best practice guidance. Despite recommendations to increase the awareness and knowledge of endometriosis in adolescence, minimal research has followed.

RESUMO

OBJECTIVE: To describe the presentation and management of children with suspected or confirmed female genital mutilation (FGM) referred to a specialist paediatric clinic. METHODS: Data collected included referral source, age, ethnicity, circumstances of FGM and clinical findings in accordance with the WHO FGM classification. RESULTS: Between September 2014 and January 2019, 148 children attended the clinic of whom 55 (37.2%) had confirmed FGM. Police or social care referred 112 (76%) children. The proportion of looked-after children (LAC) was significantly higher in the group with confirmed FGM (17/55, 31%) compared with children where FGM was not confirmed (5/93, 5%). In almost all children where FGM was confirmed, FGM was initially disclosed by the child or family (53/55, 96%) and of these 48/55 (87%) underwent FGM prior to UK entry. The remaining seven cases were British children, potentially meeting legal criteria under the FGM Act, and one resulted in a successful prosecution. CONCLUSIONS: The number of children with FGM was significantly lower than expected based on UK prevalence estimates. Most children had undergone FGM prior to UK entry, and the majority of cases were initially disclosed by the child or family themselves. These results reflect the lack of large-scale proof of the practice of FGM in the UK and are consistent with growing evidence of the abandonment of FGM among communities after migration.

RESUMO

BACKGROUND: UK and European guidelines recommend HIV testing in general practice. We report on the implementation of the Rapid HIV Assessment trial (RHIVA2) promoting HIV screening in general practice into routine care. METHODS: Interrupted time-series, difference-in-difference analysis and Pearson-correlation on three cohorts comprising 42 general practices in City & Hackney (London, UK); covering three periods: pre-trial (2009-2010), trial (2010-2012) and implementation (2012-2014). Cohorts comprised practices receiving: "trial intervention" only (n = 19), "implementation intervention" only (n = 13); and neither ("comparator") (n = 10). Primary outcomes were HIV testing and diagnosis rates per 1000 people and CD4 at diagnosis. FINDINGS: Overall, 55,443 people were tested (including 38,326 among these cohorts), and 101 people were newly diagnosed HIV positive (including 65 among these cohorts) including 74 (73%) heterosexuals and 69 (68%) people of black African/Caribbean background; with mean CD4 count at diagnosis 357 (SD=237). Among implementation intervention practices, testing rate increased by 85% (from 1·798 (95%CI=(1·657,1·938) at baseline to 3·081 (95%CI=(2·865,3·306); p = 0·0000), diagnosis rate increased by 34% (from 0·0026 (95%CI=(0·0004,0·0037)) to 0·0035 (95%CI=(0·0007,0·0062); p = 0·736), and mean CD4 count at diagnosis increased by 55% (from 273 (SD=372) to 425 (SD=274) cells per µL; p = 0·433). Implementation intervention and trial intervention practices achieved similar testing rates (3·764 vs. 3·081; 6% difference; 95% CI=(-5%,18%); p = 0·358), diagnosis rates (0·0035 vs. 0·0081; -13% difference; 95%CI=(-77%,244%; p = 0·837), and mean CD4 count (425 (SD=274) vs. 351 (SD=257); 69% increase; 95% CI=(-61%,249%); p = 0·359). HIV testing was positively correlated with diagnosis (r = 0·114 (95% CI=[0·074,0·163])), and diagnosis with CD4 count at diagnosis (r = 0·011 (95% CI=[-0·177,0·218])). INTERPRETATION: Implementation of the RHIVA programme promoting nurse-led HIV screening into routine practice in inner-city practices with high HIV prevalence increased HIV testing, and may be associated with increased and earlier diagnosis. HIV screening in primary care should be considered a key strategy to reduce undiagnosed infection particularly among high risk persons not attending sexual health services.

RESUMO

BACKGROUND: Graph theory applied to brain networks is an emerging approach to understanding the brain's topological associations with human cognitive ability. Despite well-documented cognitive impairments in bipolar disorder (BD) and recent reports of altered anatomical network organization, the association between connectivity and cognitive impairments in BD remains unclear. METHODS: We examined the role of anatomical network connectivity derived from T1- and diffusion-weighted magnetic resonance imaging in impaired cognitive performance in individuals with BD (n = 32) compared with healthy control individuals (n = 38). Fractional anisotropy- and number of streamlines-weighted anatomical brain networks were generated by mapping constrained spherical deconvolution-reconstructed white matter among 86 cortical/subcortical bilateral brain regions delineated in the individual's own coordinate space. Intelligence and executive function were investigated as distributed functions using measures of global, rich-club, and interhemispheric connectivity, while memory and social cognition were examined in relation to subnetwork connectivity. RESULTS: Lower executive functioning related to higher global clustering coefficient in participants with BD, and lower IQ performance may present with a differential relationship between global and interhemispheric efficiency in individuals with BD relative to control individuals. Spatial recognition memory accuracy and response times were similar between diagnostic groups and associated with basal ganglia and thalamus interconnectivity and connectivity within extended anatomical subnetworks in all participants. No anatomical subnetworks related to episodic memory, short-term memory, or social cognition generally or differently in BD. CONCLUSIONS: Results demonstrate selective influence of subnetwork patterns of connectivity in underlying cognitive performance generally and abnormal global topology underlying discrete cognitive impairments in BD.

RESUMO

A new development in female genital cosmetic surgery (FGCS) is the promotion of revision surgery for 'botched labiaplasty'. This content analysis study reviews the quality of information offered on websites specifically advertising revision labiaplasty. Twelve websites were identified through online searches and were examined for the quality of their clinical information. All sites defined botched labiaplasty as unsatisfactory appearance after labiaplasty. Four gave no further details and five listed asymmetry, irregular labial edges or removal of too much or too little tissue. Four websites described primary botched labiaplasty as 'mutilation'. Inadequacy of the primary surgeon was cited as the cause of botched labiaplasty in 11/12. Only two websites mentioned risks of surgery. Good outcomes were not defined and no website provided outcome data although guaranteed satisfaction was implied in two websites. This study highlights the existence and promotion of services for botched labiaplasty using non-specific and emotive descriptions. These findings suggest that unsatisfactory results from consumers' perspectives are far from uncommon. The same women whose expectations have not been met by primary surgery are now being targeted for repeat surgery with online advertising capitalising on their unchanged motivations.Impact StatementWhat is already known on this subject? Female genital cosmetic surgery (FGCS) is mainly advertised online with labiaplasty as the most commonly performed procedure. A market for labiaplasty revision to correct 'botched' primary procedures is developing. Academic literature and advertising materials are inconsistent when defining indications and determinants of success for labiaplasty or revision.What the results of this study add? A content analysis of websites specifically advertising revision labiaplasty describes the emotive and nonspecific terms used online to promote revision labiaplasty.What the implications are of these findings for clinical practice and/or further research? The existence of services for botched labiaplasty suggests dissatisfaction is common. Women whose expectations have not been met by primary surgery are targeted for repeat surgery through online advertising capitalising on their potentially unchanged motivations. This study demonstrates the need for clearer outcome data for labiaplasty and highlights the need for better advertising standards for FGCS promotion.

RESUMO

The complexities of modern policing require law enforcement agencies to expand how officers are trained to do their jobs. It is not sufficient for training to focus solely on the law or on perishable skills; such as arrest and control; defensive tactics; driving; and firearms. The present manuscript addresses the critical importance of infusing academy training with the psychological skills essential for officers to meet the contemporary challenges of police work. The authors suggest that the skills (i.e., cognitive; emotional; social; and moral) discussed in this paper may improve officers' wellness as well as promote relationships between police officers and community members. Specific methods of incorporating these skills in academy training are offered.

RESUMO

OBJECTIVES: Clitoral surgery on minors diagnosed with differences of sex development is increasingly positioned as a violation of human rights. This qualitative study identified how health professionals (HPs) navigate the contentious issues as they offer care to affected families. DESIGN: Qualitative analysis of audio-recorded semistructured interviews with HPs. All of the interviews were transcribed verbatim for theoretical thematic analysis. SETTING: Twelve specialist multidisciplinary care centres for children, adolescents and adults diagnosed with a genetic condition associated with differences of sex development. PARTICIPANTS: Thirty-two medical, surgical, psychological and nursing professionals and clinical scientists in 12 specialist centres in Britain and Sweden formed the interview sample. RESULTS: All interviewees were aware of the controversial nature of clitoral surgery and perceived themselves and their teams as non-interventionist compared with other teams. Data analyses highlighted four strategies that the interviewees used to navigate their complex tasks: (1) engaging with new thinking, (2) holding on to historical assumptions, (3) reducing the burden of dilemmas and (4) being flexible. In response to recent reports and debates that challenge clitoral surgery on minors, HPs had revised some of their opinions. However, they struggled to reconcile their new knowledge with the incumbent norms in favour of intervention as they counsel care users with variable reactions and expectations. The flexible approach taken may reflect compromise, but the interviewees were often trapped by the contradictory values and assumptions. CONCLUSIONS: If the pathology-based vocabularies and narratives about genital diversity could be modified, and normative assumptions are questioned more often, clinicians may be more adept at integrating their new knowledge into a more coherent model of care to address the psychosocial concerns that genital surgery purports to overcome.

RESUMO

BACKGROUND: Discordance between gonadal type and gender identity has often led to an assumption of infertility in patients with differences in sex development (DSD). However, there is now greater recognition of fertility being an important issue for this group of patients. Currently, gonadal tissue that may have fertility potential is not being stored for individuals with DSD and, where gonadectomy forms part of management, is often discarded. The area of fertility preservation has been predominantly driven by oncofertility which is a field dedicated to preserving the fertility of patients undergoing gonadotoxic cancer treatment. The use of fertility preservation techniques could be expanded to include individuals with DSD where functioning gonads are present. METHODS: This is a systematic literature review evaluating original research articles and relevant reviews between 1974 and 2018 addressing DSD and fertility, in vitro maturation of sperm, and histological/ultrastructural assessment of gonadal tissue in complete and partial androgen insensitivity syndrome, 17ß-hydroxysteroid dehydrogenase type 3 and 5α-reductase deficiency. CONCLUSION: Successful clinical outcomes of ovarian tissue cryopreservation are paving the way for similar research being conducted using testicular tissue and sperm. There have been promising results from both animal and human studies leading to cryopreservation of testicular tissue now being offered to boys prior to cancer treatment. Although data are limited, there is evidence to suggest the presence of reproductive potential in the gonads of some individuals with DSD. Larger, more detailed studies are required, but if these continue to be encouraging, individuals with DSD should be given the same information, opportunities and access to fertility preservation as other patient groups.

RESUMO

Face perception is impaired in older adults, but the cause of this decline is not well understood. We examined this issue by measuring Classification Images (CIs) in a face discrimination task in younger and older adults. Faces were presented in static, white visual noise, and face contrast was varied with a staircase to maintain an accuracy rate of ≈71%. The noise fields were used to construct a CI using the method described by Nagai et al. (2013) and each observer's CI was cross-correlated with the visual template of a linear ideal discriminator to obtain an estimate of the absolute efficiency of visual processing. Face discrimination thresholds were lower in younger than older adults. Like Sekuler, Gaspar, Gold, and Bennett (2004), we found that CIs from younger adults contained structure near the eyes and brows, suggesting that those observers consistently relied on information conveyed by pixels in those regions of the stimulus. CIs obtained from older adults were noticeably different: CIs from only two older adults exhibited structure near the eye/brow regions, and CIs from the remaining older observers showed no obvious structure. Nevertheless, face discrimination thresholds in both groups were strongly and similarly correlated with the cross-correlation between the CI and the ideal template, suggesting that despite older observers' lack of consistent structure, the CI method is sensitive to between-subject differences in older observers' perceptual strategy.

RESUMO

STUDY OBJECTIVE: To summarize the self-reported sexual experiences of women with vaginal agenesis before treatment and discuss the clinical implications. DESIGN: A retrospective review of pretreatment baseline sexuality data and medical records of women with vaginal agenesis seeking vaginal construction. SETTING: A specialist multidisciplinary center for women with genital differences associated with diverse sex development. PARTICIPANTS: One hundred thirty-seven women with untreated vaginal agenesis associated with Mayer-Rokitansky-Küster-Hauser Syndrome and complete androgen insensitivity syndrome aged 15 to 41 years (mean age, 20 years). INTERVENTIONS: Gynecological examination and completion of questionnaires. MAIN OUTCOME MEASURES: (1) Sexual Experiences Questionnaire; (2) Multidimensional Sexuality Questionnaire; (3) Vaginal Self-Perceptions; and (4) vaginal length. RESULTS: A sizable proportion of women reported having had sexually intimate experiences before any medical intervention on the vagina. Vaginal length, which ranged from dimple to 7 cm and averaged 2.7 cm for the cohort, was unrelated to the range of sexual experiences. Most women perceived their vagina as being too small, but less than half believed that a sexual partner would notice this. Two-thirds of the cohort subsequently completed the dilation program, which was not predicted by pretreatment vaginal length or sexual experience. CONCLUSION: Contrary to the assumption that a vagina of certain dimensions is a prerequisite for women to "have sex," many women with Mayer-Rokitansky-Küster-Hauser syndrome and complete androgen insensitivity syndrome reported having experienced genital and nongenital sexual activities with no medical interventions. It is recommended that treatment providers affirm women's capacity for sexual intimacy, relationships, and enjoyment before they introduce the topic of vaginal construction as a non-urgent choice.

RESUMO

This pilot study researched the attitudes towards and the knowledge of female genital mutilation (FGM) in adult women with FGM and their partners. The participant population consisted of English-speaking women and men over 18 years old attending specialist FGM clinics in two London hospitals. The participants completed a questionnaire on the attitudes and the knowledge of FGM, which were adapted with permission from the United Nations Children's Fund and the United States Agency for International Development household surveys. 54 participants (51 women, 3 men) took part in the surveys. 89% of participants thought that FGM should be stopped (95%CI: 0.81-0.97) and 72% said they knew FGM is illegal in the United Kingdom (UK). 15% reported that FGM caused no danger, or were unaware of any danger to women's health. This study demonstrates the opposition to FGM by participants, but some lack of knowledge regarding the legal and health implications. The exploration of attitudes in diaspora community groups is often cited as key to safeguarding girls from FGM. This is one of the first UK studies of individuals from FGM-practising communities, and we recommend use of the study questionnaires for a multicentre, cross-community study. Impact statement What is already known about this subject? Women and children are affected by female genital mutilation (FGM) globally and in the United Kingdom (UK). The majority of knowledge on practices and the attitudes towards FGM comes from UNICEF and USAID research in Africa and there is scant data on FGM practices in diaspora communities in the UK. What do the results of this study add? This study provides an appropriate questionnaire and protocol for use in community-based national research to improve healthcare for women by collecting up-to-date data on the attitudes towards FGM among the members of FGM-practising communities in the UK. What are the implications of these findings for clinical practice and further research? The implications of the results of this study are that health professionals need to understand that patients do not always know the law on FGM, even after a consultation. Health and social care professionals are placed in a unique position to work with community members to educate men and women to end FGM.

RESUMO

STUDY OBJECTIVE: To investigate specialist clinicians' experiences of treating vaginal agenesis. DESIGN: Semi-structured interviews. SETTING: Twelve hospitals in Britain and Sweden. PARTICIPANTS: Thirty-two health professionals connected to multidisciplinary teams (MDTs) including medical specialists and psychologists. INTERVENTIONS AND MAIN OUTCOME MEASURES: Theoretical thematic analysis of recorded verbatim data. RESULTS: The gynecologist and psychologist interviewees share certain observations including the importance of psychological readiness for and appropriate timing of treatment. Three overlapping themes are identified in our theoretical analysis of the MDT clinicians' talk: (1) the stigma of vaginal agenesis and the pressure to be "normal" can lead patients to minimize the time, effort, physical discomfort, and emotional cost inherent in treatment. (2) Under pressure, treatment might be presented to patients with insufficient attention to the potential psychological effect of the language used. Furthermore, the opportunity to question what is "normal" in sex is generally not taken up. It can be challenging to help the women to transcend their medicalized experiences to come to experiencing their bodies as sexual and enjoyable. (3) The reality of treatment demands, which are not always adequately processed before treatment, can lead to discontinuation and even disengagement with services. CONCLUSION: The MDT clinicians in this study emphasized the importance of psychological input in vaginal construction. However, such input should proactively question social norms about how women's genitalia should appear and function. Furthermore, rather than steering patients (back) to treatment, the entire MDT could more explicitly question social norms and help the women to do the same. By shifting the definition of success from anatomy to personal agency, the clinical focus is transformed from treatment to women.

RESUMO

INTRODUCTION: HIV remains underdiagnosed. Guidelines recommend routine HIV testing in primary care, but evidence on implementing testing is lacking. In a previous study, the Rapid HIV Assessment 2 (RHIVA2) cluster randomised controlled trial, we showed that providing training and rapid point-of-care HIV testing at general practice registration (RHIVA2 intervention) in Hackney led to cost-effective, increased and earlier diagnosis of HIV. However, interventions effective in a trial context may be less so when implemented in routine practice. We describe the protocol for an MRC phase IV implementation programme, evaluating the impact of rolling out the RHIVA2 intervention in a post-trial setting. We will use a longitudinal study to examine if the post-trial implementation in Hackney practices is effective and cost-effective, and a cross-sectional study to compare Hackney with two adjacent boroughs providing usual primary care (Newham) and an enhanced service promoting HIV testing in primary care (Tower Hamlets). METHODS AND ANALYSIS: Service evaluation using interrupted time series and cost-effectiveness analyses. We will include all general practices in three contiguous high HIV prevalence East London boroughs. All adults aged 16 and above registered with the practices will be included. The interventions to be examined are: a post-trial RHIVA2 implementation programme (including practice-based education and training, external quality assurance, incentive payments for rapid HIV testing and incorporation of rapid HIV testing in the sexual health Local Enhanced Service) in Hackney; the general practice sexual health Network Improved Service in Tower Hamlets and usual care in Newham. Coprimary outcomes are rates of HIV testing and new HIV diagnoses. ETHICS AND DISSEMINATION: The chair of the Camden and Islington NHS Research Ethics Committee, London, has endorsed this programme as an evaluation of routine care. Study results will be published in peer-reviewed journals and reported to commissioners.
