RESUMEN
INTRODUCTION AND HYPOTHESIS: The Variation in Surgical Technique study (VaST), demonstrated the large variation in surgical techniques used in native tissue (NT) anterior pelvic organ prolapse (POP) repairs. However, there are few comparative studies of different surgical techniques. This study was aimed at exploring whether surgical technique influenced the outcomes of NT anterior POP repairs. METHODS: The surgical techniques of 22 consultant surgeons performing NT anterior POP repairs were filmed and categorised. These surgeons performed 809 anterior repairs within the PROlapse Surgery: Pragmatic Evaluation and randomised Controlled Trial (PROSPECT). Logistical regression models were used to determine the influence of the different surgical techniques on subjective and objective outcomes, using data collected during PROSPECT. RESULTS: In adjusted multivariate linear regression models, fascial-flap repair was associated with an improved subjective outcome (POP-SS) compared with midline plication (ß = -2.50 [-4.42 to -0.57]; p = 0.01). At 12 months, separate fascial defect repair was associated with a poorer objective outcome than midline plication (OR 6.06 [1.82-3.52], p = 0.006). At 24 months, deep dissection was associated with a poorer POP-SS than superficial dissection (0.32-2.60, p = 0.0). Continuous-locking closure of the skin was also associated with improved POP-SS compared with continuous non-locking closure (12 months: ß = -1.94 [-3.42 to -0.45], p = 0.01). CONCLUSION: Surgical technique may influence the outcome of native tissue anterior POP repairs. Our results should not change practice but inform future research; to develop methods of explicitly recording surgical techniques and allow confirmation of the effect of these aspects of technique on outcome.

PURPOSE: The SCOFF questionnaire was designed as a simple, memorable screening tool to raise suspicion that a person might have an eating disorder. It is over 20 years since the creation of the SCOFF, during which time it has been widely used. Considering this, we wish to review the use of the SCOFF in peer-reviewed scientific journals, and to assess whether it is being used appropriately in the manner in which it was originally devised and tested. METHODS: The Preferred Reporting Items for a Systematic Review and Meta-analysis (PRISMA) guidelines were followed, and all search strategies and methods were determined before the onset of the study. PubMed and Wiley Online Library were searched using the terms SCOFF and eating. Two reviewers were involved in the reviewing process. Criteria for appropriate use of the SCOFF were formalised with the tool's original authors. RESULTS: 180 articles were included in the final review. 48 articles had used the SCOFF appropriately, 117 articles inappropriately and 15 articles had been mixed in the appropriateness of their use. CONCLUSION: This systematic review highlights the inappropriate use of the SCOFF in diverse languages and settings. When used correctly the SCOFF has made a significant contribution to the understanding of eating disorders and its simplicity has been applauded and led to widespread use. However in over two-thirds of studies, the use of the SCOFF was inappropriate and the paper highlights how and in what way it was misused, Guidelines for the appropriate use of the SCOFF are stated. Future validation and avenues of research are suggested. LEVEL OF EVIDENCE: Level I.

INTRODUCTION: Midurethral tapes (MUTs) were the most common surgical treatment for stress urinary incontinence (SUI) between 2008 and 2017. Transobturator tapes were introduced as a novel way to insert MUTs. Some women have experienced life-changing complications, and opt to undergo a total excision of transobturator tape (TETOT). There is a paucity in evidence about the outcomes of TETOT, which is a complex operation. This study aims to report clinical outcomes of all women who underwent TETOT in a specialist mesh center. METHODS: All women between 2017 and 2022 who underwent TETOT in one mesh center were reviewed. Background demographics and preoperative symptoms were recorded retrospectively. Outcome data were collected using patient global impression of improvement (PGI-I) scales via telephone review and analyzed using SPSS 25. RESULTS: Forty-five women underwent telephone review in May 2022, on average 27.9 months (range: 3-60) after TETOT. Mean age was 55 and body mass index (BMI): 30; 82% were postmenopausal, 20% were smokers, and 73.3% had recurrent SUI before excision. Indications for excision were infection (4%), vaginal exposure (24%), urethral perforation (9%), and chronic pain not associated with other complications (60%). Two women with recurrent SUI opted for a concomitant fascial sling; both reported a PGI of "very much improved" regarding SUI postoperatively. Only 12 women (26.5%) did not have SUI before excision; of these 9 (75%) reported new SUI postoperatively. Pain improved for 57.8%, but worsened for 24.4%. Although not statistically significant (p = 0.055), more women who underwent TETOT for pain alone reported worsening pain than those with pain with an additional complication (37% vs. 5.55%). Overall, 62.2% women felt "better" after their excision, 17.8% felt "worse." DISCUSSION: After TETOT, 62% of women felt better. Improvement in pain was reported by 58%-those with chronic pain without another complication reported improvement in pain less frequently (48% vs. 72%) and worsening pain more frequently (37% vs. 6%). Existing SUI worsened in 65% of women and 75% developed new SUI. There appears to be discordance between reporting global improvement with worsening of commonly measured clinical outcomes. CONCLUSION: Outcome data are important for counseling women about the risks and benefits of TETOT. Women and clinicians may have different attitudes to the possible benefits of TETOT, as evidenced by women reporting feeling better despite continuing pain or SUI. Conventional outcome measures do not adequately capture all outcomes that are important to patients.

INTRODUCTION AND HYPOTHESIS: Our aim was to compare the mid-term results of native tissue, biological xenograft and polypropylene mesh surgery for women with vaginal wall prolapse. METHODS: A total of 1348 women undergoing primary transvaginal repair of an anterior and/or posterior prolapse were recruited between January 2010 and August 2013 from 35 UK centres. They were randomised by remote allocation to native tissue surgery, biological xenograft or polypropylene mesh. We performed both 4- and 6-year follow-up using validated patient-reported outcome measures. RESULTS: At 4 and 6 years post-operation, there was no clinically important difference in Pelvic Organ Prolapse Symptom Score for any of the treatments. Using a strict composite outcome to assess functional cure at 6 years, we found no difference in cure among the three types of surgery. Half the women were cured at 6 years but only 10.3 to 12% of women had undergone further surgery for prolapse. However, 8.4% of women in the mesh group had undergone further surgery for mesh complications. There was no difference in the incidence of chronic pain or dyspareunia between groups. CONCLUSIONS: At the mid-term outcome of 6 years, there is no benefit from augmenting primary prolapse repairs with polypropylene mesh inlays or biological xenografts. There was no evidence that polypropylene mesh inlays caused greater pain or dyspareunia than native tissue repairs.

BACKGROUND: The CRADLE (Community blood pressure monitoring in Rural Africa: Detection of underLying pre-Eclampsia) Vital Signs Alert device-designed specifically to improve maternity care in low resource settings-had varying impact when trialled in different countries. To better understand the contextual factors that may contribute to this variation, this study retrospectively evaluated the adoption of CRADLE, during scale-up in Sierra Leone. METHODS: This was a mixed methods study. A quantitative indicator of adoption (the proportion of facilities trained per district) was calculated from existing training records, then focus groups were held with 'CRADLE Champions' in each district (n = 32), to explore adoption qualitatively. Template Analysis was used to deductively interpret qualitative data, guided by the NASSS (non-adoption, abandonment, scale-up, spread, sustainability) Framework. FINDINGS: Substantial but non-significant variation was found in the proportion of facilities trained in each district (range 59-90%) [X2 (7, N = 8) = 10.419, p = 0.166]. Qualitative data identified complexity in two NASSS domains that may have contributed to this variation: 'the technology' (for example, charging issues, difficulty interpreting device output and concerns about ongoing procurement) and 'the organisation' (for example, logistical barriers to implementing training, infighting and high staff turnover). Key strategies mentioned to mitigate against these issues included: transparent communication at all levels; encouraging localised adaptations during implementation (including the involvement of community leaders); and selecting Champions with strong soft skills (particularly conflict resolution and problem solving). CONCLUSIONS: Complexity related to the technology and the organisational context were found to influence the adoption of CRADLE in Sierra Leone, with substantial inter-district variation. These findings emphasise the importance of gaining an in-depth understanding of the specific system and context in which a new healthcare technology is being implemented. This study has implications for the ongoing scale-up of CRADLE, and for those implementing or evaluating other health technologies in similar contexts.
Many women die during pregnancy and childbirth from causes that could be prevented, and the vast majority of these deaths occur in low-resource settings. The 'CRADLE Vital Signs Alert' is a medical device that helps identify problems during pregnancydesigned specifically for healthcare professionals in low-resource settings. However, for unknown reasons, the device appears to have varying impact according to the country or setting in which it is used. This study aimed to explore in depth whether, and why, healthcare professionals in Sierra Leone adopted the device and engaged in training (or not). Between March 2020 and January 2021, the CRADLE device and training package was disseminated across 8 districts in Sierra Leone. This relied on a few healthcare workers (nominated 'CRADLE Champions') to voluntarily distribute the devices and training in their local areas. Group discussions were held with CRADLE Champions in each district after the rollout to gather their feedback. In addition, the proportion of facilities trained in each district was recorded. The study found differences in how well the device and training was adopted in each district. Common challenges reported across districts related to technological difficulties (such as issues charging the devices) and organisational barriers (such as high levels of staff turnover at facilities). These findings will help to inform future rollout of the CRADLE device and training in Sierra Leone and highlight factors that may need to be considered by those implementing other health technologies in similar settings.

BACKGROUND: There is much debate surrounding the ideal antiseptic skin preparation agent to reduce postoperative surgical site infection. International guidelines suggest that chlorhexidine- and alcohol-containing compounds have superior efficacy. However, there are minimal clinical trials specifically looking at skin preparation agents for colorectal surgery. OBJECTIVE: The aim of this study was to compare the efficacy of chlorhexidine in alcohol versus povidone-iodine in alcohol versus povidone-iodine in aqueous solution for the prevention of surgical site infection in colorectal surgery. DESIGN: This is a prospective, 3-armed, randomized controlled trial. SETTING: This study was conducted at the 800-bed John Hunter Hospital and Newcastle Private Hospital, with all subspecialty services in New South Wales, Australia. PATIENTS: All eligible, consenting adults undergoing colorectal surgery between July 2015 and December 2018 were included. INTERVENTIONS: Patients were andomized to receive preincision skin preparation with one of the following: chlorhexidine in 70% alcohol, povidone-iodine in 70% alcohol, or povidone-iodine in aqueous solution. MAIN OUTCOME MEASURE: The primary measure was surgical site infection within 30 days. RESULTS: A total of 482 patients were randomized to chlorhexidine in alcohol, povidone-iodine in alcohol, or aqueous povidone-iodine. The overall surgical site infection rate was 22% (107/482). There was no difference in rates of surgical site infection: 20.6% (29/141), 22.8% (44/193), and 23.0% (34/148), respectively ( p = 0.5267). There was no difference in complication rates: 54.6% (77/141), 46.1% (89/193), and 49.3% (73/148), respectively ( p = 0.1762). The median length of stay was 6 days in all 3 groups. LIMITATIONS: This is a subset analysis of a larger clinical trial for all forms of incisional surgery (the NewSKIN Prep trial), and noninferiority cannot be assessed. Changes in government regulations resulted in a change from 0.5% chlorhexidine in 70% ethanol to 2% chlorhexidine in 70% ethanol during the trial. CONCLUSION: This large, prospective, randomized clinical trial appears to indicate that there is no difference in surgical site infection, complications, or length of stay among the 3 commonest forms of skin preparation in colorectal surgery.

ANTECEDENTES: Existe un gran debate en torno al agente de preparación de la piel antiséptico ideal para reducir la infección posoperatoria del sitio quirúrgico. Las pautas internacionales sugieren que los compuestos que contienen clorhexidina y alcohol tienen una eficacia. Sin embargo, existen ensayos clínicos mínimos que analizan específicamente los agentes de preparación de la piel para la cirugía colorrectal. OBJETIVO: Comparar la eficacia de la clorhexidina en alcohol versus povidona yodada en alcohol versus povidona yodada en solución acuosa para la prevención de la infección del sitio quirúrgico en cirugía colorrectal. DISEO: Este es un ensayo controlado aleatorio prospectivo de tres brazos. AJUSTE: Este estudio se realizó en el Hospital John Hunter de 800 camas y el Hospital Privado de Newcastle con todos los servicios de subespecialidad en Nueva Gales del Sur, Australia. PACIENTES: Se incluyeron todos los adultos elegibles que dieron su consentimiento para someterse a una cirugía colorrectal entre julio de 2015 y diciembre de 2018. INTERVENCIONES: Aleatorizados para recibir una preparación para la piel previa a la incisión con uno de: clorhexidina en alcohol al 70%, povidona yodada en alcohol al 70% o povidona yodada en solución acuosa. MEDIDA DE RESULTADO PRINCIPAL: La medida principal fue la infección del sitio quirúrgico dentro de los 30 días. RESULTADOS: Un total de 482 pacientes fueron aleatorizados para recibir clorhexidina en alcohol, povidona yodada en alcohol o povidona yodada acuosa. La tasa global de infección del sitio quirúrgico fue del 22% (107/482). No hubo diferencias en las tasas de infección del sitio quirúrgico; 20,6% (29/141), 22,8% (44/193) y 23,0% (34/148) respectivamente; p = 0,5267. No hubo diferencia en las tasas de complicaciones; 54,6% (77/141), 46,1% (89/193) y 49,3% (73/148) respectivamente; p = 0,1762. La duración media de la estancia hospitalaria fue de 6,0 días en los tres grupos. LIMITACIONES: Este es un análisis de subconjunto de un ensayo clínico más grande para todas las formas de cirugía incisional (el ensayo NewSKIN Prep) y no se puede evaluar la no inferioridad. Los cambios en las regulaciones gubernamentales dieron como resultado un cambio de clorhexidina al 0,5% en etanol al 70% a clorhexidina al 2% en etanol al 70% durante la prueba. CONCLUSINES: Este gran ensayo clínico prospectivo y aleatorizado parece indicar que no hay diferencia en la infección del sitio quirúrgico, las complicaciones o la duración de la estancia entre las 3 formas más comunes de preparación de la piel en la cirugía colorrectal.

INTRODUCTION AND HYPOTHESIS: Health literacy underpins informed consent and shared decision-making. In gynaecology, this includes understanding of normal anatomy and urogenital disease. This study evaluated public knowledge of external female genital anatomy and pelvic organ prolapse (POP). METHODS: A questionnaire study asked participants for their demographics and to label a female external genitalia diagram and included free-text questions on POP, its symptoms and treatment. Questionnaires were distributed at general outpatient (OPD) and urogynaecology (UG) departments at a UK teaching hospital. Differences in the number of correct anatomy labels between participant genders were assessed via chi-squared tests and, within female participants, multivariable linear and logistic regressions assessed associations with increasing correct anatomical labels and an understanding (versus no understanding) of POP, respectively. RESULTS: Within 191 (n = 160 OPD, n = 31 UG), 9/103 (9%) labelled all anatomical structures correctly. Females had more correct labels (median 1, IQR 0,3) versus males (median 0, IQR 0,1), P = 0.022). Higher education (vs. < secondary) and white ethnicity were associated with greater numbers of correct labels [coefficient (95% CI): 1.05 (0.14, 1.96), P = 0.024, 1.45 (0.58, 2.33), P = 0.001 respectively]. Fifty-three per cent understood POP. POP understanding increased with increasing age, white ethnicity (OR: 4.38, 95% CI: 1.36, 14.08, P = 0.013) and more correct anatomy labels (OR: 1.43, 95% CI 1.14, 1.79, P = 0.002). Of those who understood POP, only 35% identified "bulge" as a symptom and 7% physiotherapy as a treatment option. CONCLUSION: There was poor public understanding of external female genital anatomy and POP, which may have significant implications for health-seeking, shared decision-making and informed consent.

BACKGROUND: Many people living with chronic kidney disease (CKD) are iron deficient, even though they may not be anaemic. The Iron and Muscle study aims to evaluate whether iron supplementation reduces symptoms of fatigue, improves muscle metabolism, and leads to enhanced exercise capacity and physical function. We report here the trial design and baseline characteristics. METHODS: This is a prospective, double-blind multicentre randomised controlled trial (RCT) including 75 non-dialysis stage 3-4 CKD patients with iron deficiency but without anaemia. Patients were randomly (1:1) assigned to either: i) intravenous iron therapy, or ii) placebo, with concurrent recruitment of eight CKD non-iron deficient participants and six healthy volunteers. The primary outcome of the study is the six-minute walk test (6MWT) distance between baseline and four-weeks. An additional exercise training programme for patients in both groups was initiated and completed between 4 and 12 weeks, to determine the effect of iron repletion compared to placebo treatment in the context of patients undertaking an exercise programme. Additional secondary outcomes include fatigue, physical function, muscle strength, muscle metabolism, quality of life, resting blood pressure, clinical chemistry, safety and harms associated with the iron therapy intervention and the exercise training intervention, and hospitalisations. All outcomes were conducted at baseline, 4, and 12 weeks, with a nested qualitative study, to investigate the experience of living with iron deficiency and intervention acceptability. The cohort have been recruited and baseline assessments undertaken. RESULTS: Seventy-five individuals were recruited. 44% of the randomised cohort were male, the mean (SD) age was 58 (14) years, and 56% were White. Body mass index was 31 (7) kg/m2; serum ferritin was 59 (45) µg/L, transferrin saturation was 22 (10) %, and haemoglobin was 125 (12) g/L at randomisation for the whole group. Estimated glomerular filtration rate was 35 (12) mL/min/1.73 m2 and the baseline 6MWT distance was 429 (174) m. CONCLUSION: The results from this study will address a substantial knowledge gap in the effects of intravenous iron therapy, and offer potential clinical treatment options, to improve exercise capacity, physical function, fatigue, and muscle metabolism, for non-dialysis patients with CKD who are iron-deficient but not anaemic. It will also offer insight into the potential novel effects of an 8-week exercise training programme. TRIAL REGISTRATION: EudraCT: 2018-000,144-25 Registered 28/01/2019.

PURPOSE: Natural Killer (NK) cells are a vital part of immune surveillance and have been implicated in colorectal cancer development and prognosis. This systematic review aims to distil the literature on NK cells as it relates to colorectal cancer. METHODS: All published studies over 10 years relating to NK cells and colorectal cancer were reviewed. All studies publishing in English, searchable via pubmed or through reference review and reporting directly on the nature or function of NK cells in colorectal cancer patients were included. Outcomes were determined as alterations or new information regarding NK cells in colorectal cancer patients. RESULTS: Natural killer cells may be implicated in the development of colorectal cancer and may play a role in prognostication of the disease. NK cells are altered by the treatment (both surgical and medical) of colorectal cancer and it seems likely that they will also be a target for manipulation to improve colorectal cancer survival. CONCLUSIONS: NK cell morphology and function are significantly affected by the development of colorectal cancer. Observation of NK cell changes may lead to earlier detection and better prognostication in colorectal cancer. Further study is needed into immunological manipulation of NK cells which may lead to improved colorectal cancer survival.

OBJECTIVES: Oropharyngeal squamous cell carcinoma is the most common human papillomavirus (HPV)-associated cancer in the UK, but little is known about the prevalence of oropharyngeal HPV in sexually active teenagers. We investigated reported HPV vaccination coverage (in females) and prevalence of oropharyngeal HPV in sexually active students attending six technical colleges in London, UK. METHODS: In 2017, we obtained mouthwash samples and questionnaires from male and female students taking part in the 'Test n Treat' chlamydia screening trial. Samples were subjected to HPV genotyping. RESULTS: Of 232 participants approached, 202 (87%) provided a mouthwash sample and questionnaire. Participants' median age was 17 years and 47% were male. Most (73%) were from black and minority ethnic groups, 64% gave a history of oral sex, 52% reported having a new sexual partner in the past 6 months, 33% smoked cigarettes, 5.9% had concurrent genitourinary Chlamydia trachomatis infection and 1.5% Neisseria gonorrhoeae and 5.0% were gay or bisexual. Only 47% (50/107) of females reported being vaccinated against HPV 16/18, of whom 74% had received ≥2 injections. HPV genotyping showed three mouthwash samples (1.5%, 95% CI 0.3% to 4.3%) were positive for possible high-risk human papillomavirus (HR-HPV), one (0.5%, 0.0% to 2.7%) for low-risk HPV 6/11, but none (0.0%, 0.0% to 1.8%) for HR-HPV. Four samples (2.0%, 0.5% to 5.0%) were positive for HPV16 using a HPV16 type-specific quantitative PCR, but these were at a very low copy number and considered essentially negative. CONCLUSIONS: Despite the high prevalence of oral sex and genitourinary chlamydia and low prevalence of HPV vaccination, the prevalence of oropharyngeal HR-HPV in these adolescents was negligible.

OBJECTIVES: Glycaemia in people with type 1 diabetes and disordered eating is not well characterised. We explored the glycaemia, self-care behaviour and emotional state of women with type 1 diabetes and disordered eating. RESEARCH DESIGN AND METHODS: In all, 13 women with and 10 without disordered eating and type 1 diabetes participated in this case-control study. We used a mixed-methods approach with a 7-day blinded continuous glucose monitoring and real-time record of non-prompted capillary glucose (CG), emotion, activity and physical symptoms on a diabetes diary using a smartphone application (mySugr®). We compared groups using Mann-Whitney U test or Fisher's exact test. We conducted thematic analyses of free-text diary entries (NVivo®) and quantitative analysis of emotion/symptom tags. RESULTS: People with type 1 diabetes and disordered eating spent longer time above range in level 2 hyperglycaemia (>13.9 mmol/L, Median [interquartile range]: 21% [16,60] vs 5% [2,17], p = 0.015). They had lower time in range and similar time below range compared to those without disordered eating. The standard deviation of CG was significantly higher in the disordered eating group (4.7 mmol/L [4.5, 6.1] vs 3 [2.8, 3.2], p = 0.018). The median of the percentage of rising sensor glucose trends was three times higher in the disordered eating group. They also had higher negative emotional and physical symptoms associated with high blood glucose (>15 mmol/L). CONCLUSIONS: Disordered eating has a significant impact on the glycaemia and emotion of a person with type 1 diabetes.

AIMS: To determine terminology and methods for raising intra-abdominal pressure (IAP) currently used by clinicians to assess pelvic floor dysfunction (PFD) and to measure the effect of these maneuvers on IAP. METHODS: Three-hundred questionnaires were distributed at two scientific meetings in the United Kingdom to determine methods clinicians used to raise IAP and their perceptions of these methods. Twenty healthy volunteers were also recruited to measure the effect of two methods of raising IAP: Valsalva maneuver (VM) and bear down maneuver (BDM). IAP pressure was measured with rectal catheters connected to pressure sensors. The IAP was measured during each maneuver in both standing and supine positions. RESULTS: Maneuvers used in practice were cough (79%), BDM (60%), and VM (38%). 44% of clinicians felt patients found it difficult to raise their IAP. There was uncertainty among clinicians as to which method was the most effective in raising IAP and whether the different methods produced the same rise in IAP. On testing IAP in 20 healthy volunteers, median (interquartile range) IAP generated during BDM; 101 (59.1) cmH2 O was significantly higher than that generated during VM; 80.3 (43.6) cmH2 O (p < .0001). CONCLUSION: Clinicians varied widely in the maneuvers they used to raise patients' IAP to test for PFD and there was uncertainty about the maneuvers' effect on IAP. In healthy volunteers, BDM produced significantly higher IAP than VM. We recommend standardization of terminology and techniques used to raise IAP when assessing PFD, to ensure consistency of diagnosis and assessment of treatment outcomes.

CONTEXT: There are few UK data on the prevalence and clustering of risky behaviours in ethnically diverse adolescents. OBJECTIVES: To investigate the prevalence of reported alcohol use, smoking and vaping, and explore whether these behaviours are associated with increased numbers of sexual partners. DESIGN: Questionnaire survey of 'Test n Treat' chlamydia screening trial participants. SETTING AND PARTICIPANTS: Sexually active students attending six London technical colleges completed confidential questionnaires and provided genitourinary samples. RESULTS: The median age of the 509 participants was 17 years (IQR: 16-18), 47% were male, 50% were of black ethnicity, 55% reported ≥2 sexual partners in the past year (67% of males and 45% of females) and 6.2% had chlamydia infection and 0.6% gonorrhoea. Almost half (48%) reported getting drunk in the past month, 33% smoked cigarettes and 7% had ever vaped. A larger percentage of students with ≥2 sexual partners than 0-1 partners reported getting drunk in the past month (53.7%, 144/268% versus 42.2% 94/223, adjusted prevalence ratio: 1.33, 95% confidence interval: 1.11-1.61) and smoking cigarettes (36.6%, 100/273% versus 30.2%, 67/222, 1.34 (1.05-1.70)). By contrast, multiple sexual partners were not associated with vaping or chlamydia infection, but numbers were small. CONCLUSIONS: We found high prevalences of risky behaviour and an association between multiple sexual partners and smoking and/or getting drunk. Findings support the introduction of compulsory sex and relationship education in UK secondary schools, including information about the adverse effects of alcohol and smoking.

BACKGROUND: Conventional myocardial T1 mapping techniques such as modified Look-Locker inversion recovery (MOLLI) generate one T1 map per breathhold. T1 mapping with full left ventricular coverage may be desirable when spatial T1 variations are expected. This would require multiple breathholds, increasing patient discomfort and prolonging scan time. PURPOSE: To develop and characterize a novel FASt single-breathhold 2D multislice myocardial T1 mapping (FAST1) technique for full left ventricular coverage. STUDY TYPE: Prospective. POPULATION/PHANTOM: Numerical simulation, agarose/NiCl2 phantom, 9 healthy volunteers, and 17 patients. FIELD STRENGTH/SEQUENCE: 1.5T/FAST1. ASSESSMENT: Two FAST1 approaches, FAST1-BS and FAST1-IR, were characterized and compared with standard 5-(3)-3 MOLLI in terms of accuracy, precision/spatial variability, and repeatability. STATISTICAL TESTS: Kruskal-Wallis, Wilcoxon signed rank tests, intraclass correlation coefficient analysis, analysis of variance, Student's t-tests, Pearson correlation analysis, and Bland-Altman analysis. RESULTS: In simulation/phantom, FAST1-BS, FAST1-IR, and MOLLI had an accuracy (expressed as T1 error) of 0.2%/4%, 6%/9%, and 4%/7%, respectively, while FAST1-BS and FAST1-IR had a precision penalty of 1.7/1.5 and 1.5/1.4 in comparison with MOLLI, respectively. In healthy volunteers, FAST1-BS/FAST1-IR/MOLLI led to different native myocardial T1 times (1016 ± 27 msec/952 ±22 msec/987 ± 23 msec, P < 0.0001) and spatial variability (66 ± 10 msec/57 ± 8 msec/46 ± 7 msec, P < 0.001). There were no statistically significant differences between all techniques for T1 repeatability (P = 0.18). In vivo native and postcontrast myocardial T1 times in both healthy volunteers and patients using FAST1-BS/FAST1-IR were highly correlated with MOLLI (Pearson correlation coefficient ≥0.93). DATA CONCLUSION: FAST1 enables myocardial T1 mapping with full left ventricular coverage in three separated breathholds. In comparison with MOLLI, FAST1 yield a 5-fold increase of spatial coverage, limited penalty of T1 precision/spatial variability, no significant difference of T1 repeatability, and highly correlated T1 times. FAST1-IR provides improved T1 precision/spatial variability but reduced accuracy when compared with FAST1-BS. LEVEL OF EVIDENCE: 1 Technical Efficacy: Stage 3 J. Magn. Reson. Imaging 2020;51:492-504.

INTRODUCTION: Women with pelvic organ prolapse describe vaginal laxity and poor sensation of vaginal tone that does not correlate with anatomical findings. This discrepancy could be explained by altered vaginal sensation and a test that could measure sensation of vaginal tone, transmitted via Aα and Aß nerve fibers, would further our understanding of the pathophysiology of vaginal laxity. OBJECTIVE: To develop quantitative sensory testing (QST) for vaginal tone using genital stretch perception thresholds (PT), assess reproducibility, and the association with age and parity. STUDY DESIGN: Prospective observational cohort study of healthy women (Canadian task force classification II-2) who underwent QST method of limits at the vagina and introitus for sensation of first awareness and stretch using a modified anorectal physiology protocol. RESULTS: Forty women underwent repeatability testing. Intra- and inter-rater repeatability using intraclass correlation coefficients (ICC) was good to excellent for both first awareness and stretch at the vagina and introitus (intra-rater ICC = 0.93, 0.95, 0.81, and 0.88, respectively; inter-rater ICC = 0.83, 0.93, 0.71, and 0.86 respectively). Normative data were collected from 100 women. Log-linear regression found a significant association between age and PT for first awareness and stretch at the vagina and introitus (P = .020, .008, .002, and <.001, respectively). There was no association with parity and PT. Nomograms were calculated using the 95% confidence limits around the regression line. CONCLUSIONS: Stretch QST is clinically feasible, valid, and reproducible. The test can be used as a tool to measure sensation in women presenting with symptoms of vaginal laxity.

BACKGROUND: The clinical effectiveness of neurally adjusted ventilatory assist (NAVA) has yet to be demonstrated, and preliminary studies are required. The study aim was to assess the feasibility of a randomized controlled trial (RCT) of NAVA versus pressure support ventilation (PSV) in critically ill adults at risk of prolonged mechanical ventilation (MV). METHODS: An open-label, parallel, feasibility RCT (n = 78) in four ICUs of one university-affiliated hospital. The primary outcome was mode adherence (percentage of time adherent to assigned mode), and protocol compliance (binary-≥ 65% mode adherence). Secondary exploratory outcomes included ventilator-free days (VFDs), sedation, and mortality. RESULTS: In the 72 participants who commenced weaning, median (95% CI) mode adherence was 83.1% (64.0-97.1%) and 100% (100-100%), and protocol compliance was 66.7% (50.3-80.0%) and 100% (89.0-100.0%) in the NAVA and PSV groups respectively. Secondary outcomes indicated more VFDs to D28 (median difference 3.0 days, 95% CI 0.0-11.0; p = 0.04) and fewer in-hospital deaths (relative risk 0.5, 95% CI 0.2-0.9; p = 0.032) for NAVA. Although overall sedation was similar, Richmond Agitation and Sedation Scale (RASS) scores were closer to zero in NAVA compared to PSV (p = 0.020). No significant differences were observed in duration of MV, ICU or hospital stay, or ICU, D28, and D90 mortality. CONCLUSIONS: This feasibility trial demonstrated good adherence to assigned ventilation mode and the ability to meet a priori protocol compliance criteria. Exploratory outcomes suggest some clinical benefit for NAVA compared to PSV. Clinical effectiveness trials of NAVA are potentially feasible and warranted.

INTRODUCTION AND HYPOTHESIS: This was an observational study aiming to determine factors which influence women's choice of surgery for primary stress urinary incontinence (SUI). METHODS: Two hundred twelve women undergoing a primary SUI procedure were recruited to this study from 12 hospitals in the north of England. After choosing a procedure, women were asked to complete a standardized semi-structured questionnaire about their health, demographics and a free text box to record factors important to them when choosing their procedure. Statistical analysis was performed to determine the impact of demographic, lifestyle or healthcare factors on women's decision-making. Thematic analysis of the free text data was performed to identify factors important for women when choosing a surgical procedure. RESULTS: Sixty-four percent of women chose urethral bulking. There was no significant difference among age, BMI, smoking status or previous laparotomy between women choosing the four types of surgery. Women were less likely to choose urethral bulking if seen in a tertiary centre compared with a secondary centre (p < 001). Major themes in decision-making were efficacy, invasiveness, recovery, risk of complications, use of mesh, the clinician, the media, hierarchy of treatments and type of anaesthetic. Some women expressed a hierarchical approach to treatment. CONCLUSIONS: Our findings suggest decision-making is not influenced by patient factors such as age, BMI, smoking status or previous laparotomies. Women's choices are a complex mix of factors and not simply related to efficacy.

INTRODUCTION: The PROSPECT study found that outcomes for native tissue and mesh prolapse repairs are similar but mesh repairs have a 10% risk of exposure. The current UK surgical mesh pause has led to renewed interest in native tissue surgery. Previous studies of native tissue anterior repair surgical techniques have been limited by the questionnaire study design. The objective of this study was to describe and categorise native tissue anterior repair surgical techniques. METHODS: This prospective qualitative study used a purposive sampling strategy to recruit surgeons. Data were collected through video-recorded observations of surgery, audio-recorded interviews with surgeons and field notes. The study took place in urogynaecology theatres in 21 UK centres. Thematic analysis was performed using computer-based software and themes of surgical technique were developed. RESULTS: Thirty consultant surgeons were recruited. In all steps of the anterior repair procedure, infiltration, dissection, method of fascial repair, type and method of suturing and suture placement, surgical technique varied between surgeons. The filming of surgery followed by immediate validation with the surgeons gave greater insight. Surgeons' terminology to describe techniques varied and the investigators' opinions of the techniques performed were not always consistent with the surgeons' descriptions. The concept of fascia in histological terms was not uniform amongst surgeons. CONCLUSION: VaST has demonstrated significant variation in native tissue anterior repair surgical techniques and inconsistency in the terminology used to describe them. These inconsistencies may prevent future meaningful research of prolapse surgery. The variation in technique could affect surgical outcomes and this should be explored further.

BACKGROUND: Low uptake of sexually transmitted infection testing by sexually active young people is a worldwide public health problem. Screening in non-medical settings has been suggested as a method to improve uptake. The "Test n Treat" feasibility trial offered free, on-site rapid chlamydia/gonorrhoea tests with same day treatment for chlamydia (and gonorrhoea treatment at a local clinic,) to sexually active students (median age 17 years) at six technical colleges in London. Despite high rates of chlamydia (6% prevalence), uptake of testing was low (< 15%). In a qualitative study we explored the acceptability, including barriers and facilitators to uptake, of on-site chlamydia screening. METHODS: In 2016-17 we conducted a qualitative study in the interpretative tradition using face to face or telephone semi-structured interviews with students (n = 26), teaching staff (n = 3) and field researchers (n = 4). Interviews were digitally recorded, transcribed and thematically analysed. RESULTS: From the student perspective, feelings of embarrassment and the potential for stigma were deterrents to sexually transmitted infection testing. While the non-medical setting was viewed as mitigating against stigma, for some students volunteering to be screened exposed them to detrimental judgements by their peers. A small financial incentive to be screened was regarded as legitimising volunteering in a non-discrediting way. Staff and researchers confirmed these views. The very low level of knowledge about sexually transmitted infections influenced students to not view themselves as candidates for testing. There were also suggestions that some teenagers considered themselves invulnerable to sexually transmitted infections despite engaging in risky sexual behaviours. Students and researchers reported the strong influence peers had on uptake, or not, of sexually transmitted infection testing. CONCLUSIONS: This study offers new insights into the acceptability of college-based sexually transmitted infection screening to young, multi-ethnic students. Future studies in similar high risk, hard to reach groups should consider linking testing with education about sexually transmitted infections, offering non stigmatising incentives and engaging peer influencers.

BACKGROUND: Community-based screening may be one solution to increase testing and treatment of sexually transmitted infections in sexually active teenagers, but there are few data on the practicalities and cost of running such a service. We estimate the cost of running a 'Test n Treat' service providing rapid chlamydia (CT) and gonorrhoea (NG) testing and same day on-site CT treatment in technical colleges. METHODS: Process data from a 2016/17 cluster randomised feasibility trial were used to estimate total costs and service uptake. Pathway mapping was used to model different uptake scenarios. Participants, from six London colleges, provided self-taken genitourinary samples in the nearest toilet. Included in the study were 509 sexually active students (mean 85/college): median age 17.9 years, 49% male, 50% black ethnicity, with a baseline CT and NG prevalence of 6 and 0.5%, respectively. All participants received information about CT and NG infections at recruitment. When the Test n Treat team visited, participants were texted/emailed invitations to attend for confidential testing. Three colleges were randomly allocated the intervention, to host (non-incentivised) Test n Treat one and four months after baseline. All six colleges hosted follow-up Test n Treat seven months after baseline when students received a £10 incentive (to participate). RESULTS: The mean non-incentivised daily uptake per college was 5 students (range 1 to 17), which cost £237 (range £1082 to £88) per student screened, and £4657 (range £21,281 to £1723) per CT infection detected, or £13,970 (range £63,842 to £5169) per NG infection detected. The mean incentivised daily uptake was 19 students which cost £91 per student screened, and £1408/CT infection or £7042/NG infection detected. If daily capacity for screening were achieved (49 students/day), costs including incentives would be £47 per person screened and £925/CT infection or £2774/NG infection detected. CONCLUSIONS: Delivering non-incentivised Test n Treat in technical colleges is more expensive per person screened than CT and NG screening in clinics. Targeting areas with high infection rates, combined with high, incentivised uptake could make costs comparable. TRIAL REGISTRATION: ISRCTN58038795, Assigned August 2016, registered prospectively.
