Brown RG, Al-Memar M, Marchesi JR, Lee YS, Smith A, Chan D, Lewis H, Kindinger L, Terzidou V, Bourne T, Bennett PR, MacIntyre DAet al., 2019, Establishment of vaginal microbiota composition in early pregnancy and its association with subsequent preterm prelabour rupture of the fetal membranes, Translational Research, Vol: 207, Pages: 30-43, ISSN: 1931-5244

Vaginal bacterial community composition influences pregnancy outcome. Preterm prelabor rupture of the fetal membranes (PPROM), which precedes 30% of all spontaneous preterm births, is associated with high vaginal bacterial diversity prior to rupture. The point at which vaginal bacterial diversity is established before PPROM is unknown. In this study, we use metataxonomics to longitudinally characterize the vaginal bacterial composition from as early as 6 weeks of gestation in women at high (n = 38) and low (n = 22) risk of preterm birth who subsequently experience PPROM and in women delivering at term without complications (n = 36). Reduced Lactobacillus spp. abundance and high diversity was observed prior to PPROM in 20% and 26% of women at low and high risk of preterm births respectively, but in only 3% of women who delivered at term. PPROM was associated with instability of bacterial community structure during pregnancy and a shift toward higher diversity predominately occurring during the second trimester. This was characterized by increased relative abundance of potentially pathogenic species including Prevotella, Peptoniphilus, Streptococcus, and Dialister. This study identifies reduced Lactobacillus spp. abundance and increasing vaginal bacterial diversity as an early risk factor for PPROM and highlights the need for interventional studies designed to assess the impact of modifying vaginal bacterial composition for the prevention of preterm birth.

OBJECTIVE: To develop a uniform classification and standardized reporting system of ultrasound findings of adenomyosis using the Morphological Uterus Sonographic Assessment (MUSA) criteria. METHOD: The opinion presented in this manuscript was built based on a thorough discussion among all authors, including a Delphi procedure. Selected images and videos of typical cases of the different morphological variations of adenomyosis were used in the debates. RESULTS: A classification and reporting system of different types of adenomyosis based on ultrasound was agreed upon including (1) identification of adenomyosis based on MUSA criteria, (2) disease location (anterior, posterior, left lateral, right lateral, fundal), (3) classification of the lesions as focal or diffuse, (4) presence or absence of intralesional cysts, (5) myometrial layer involvement (junctional zone, myometrium, serosal involvement), (6) disease extent (< 25%, 25-50%, > 50% of uterine volume affected by adenomyosis) and (7) lesion size. CONCLUSIONS: We proposes a uniform classification and reporting system of different types of adenomyosis based on ultrasound. The clinical relevance of this approach needs to be evaluated in further studies. This article is protected by copyright. All rights reserved.

Craciunas L, Gallos I, Chu J, Bourne T, Quenby S, Brosens JJ, Coomarasamy Aet al., 2019, Conventional and modern markers of endometrial receptivity: a systematic review and meta-analysis, Human Reproduction Update, Vol: 25, Pages: 202-223, ISSN: 1355-4786

BACKGROUND: Early reproductive failure is the most common complication of pregnancy with only 30% of conceptions reaching live birth. Establishing a successful pregnancy depends upon implantation, a complex process involving interactions between the endometrium and the blastocyst. It is estimated that embryos account for one-third of implantation failures, while suboptimal endometrial receptivity and altered embryo-endometrial dialogue are responsible for the remaining two-thirds. Endometrial receptivity has been the focus of extensive research for over 80 years, leading to an indepth understanding of the processes associated with embryo-endometrial cross-talk and implantation. However, little progress has been achieved to translate this understanding into clinically meaningful prognostic tests and treatments for suboptimal endometrial receptivity. OBJECTIVE AND RATIONALE: The objective of this systematic review was to examine the evidence from observational studies supporting the use of endometrial receptivity markers as prognostic factors for pregnancy outcome in women wishing to conceive, in order to aid clinicians in choosing the most useful marker in clinical practice and for informing further research. SEARCH METHODS: The review protocol was registered with PROSPERO (CRD42017077891). MEDLINE and Embase were searched for observational studies published from inception until 26 February 2018. We included studies that measured potential markers of endometrial receptivity prior to pregnancy attempts and reported the subsequent pregnancy outcomes. We performed association and accuracy analyses using clinical pregnancy as an outcome to reflect the presence of receptive endometrium. The Newcastle-Ottawa scale for observational studies was employed to assess the quality of the included studies. OUTCOMES: We included 163 studies (88 834 women) of moderate overall quality in the narrative synthesis, out of which 96 were included in the meta-analyses. Studies reported on

BACKGROUND: Ovarian tumours are usually surgically removed because of the presumed risk of complications. Few large prospective studies on long-term follow-up of adnexal masses exist. We aimed to estimate the cumulative incidence of cyst complications and malignancy during the first 2 years of follow-up after adnexal masses have been classified as benign by use of ultrasonography. METHODS: In the international, prospective, cohort International Ovarian Tumor Analysis Phase 5 (IOTA5) study, patients aged 18 years or older with at least one adnexal mass who had been selected for surgery or conservative management after ultrasound assessment were recruited consecutively from 36 cancer and non-cancer centres in 14 countries. Follow-up of patients managed conservatively is ongoing at present. In this 2-year interim analysis, we analysed patients who were selected for conservative management of an adnexal mass judged to be benign on ultrasound on the basis of subjective assessment of ultrasound images. Conservative management included ultrasound and clinical follow-up at intervals of 3 months and 6 months, and then every 12 months thereafter. The main outcomes of this 2-year interim analysis were cumulative incidence of spontaneous resolution of the mass, torsion or cyst rupture, or borderline or invasive malignancy confirmed surgically in patients with a newly diagnosed adnexal mass. IOTA5 is registered with ClinicalTrials.gov, number NCT01698632, and the central Ethics Committee and the Belgian Federal Agency for Medicines and Health Products, number S51375/B32220095331, and is ongoing. FINDINGS: Between Jan 1, 2012, and March 1, 2015, 8519 patients were recruited to IOTA5. 3144 (37%) patients selected for conservative management were eligible for inclusion in our analysis, of whom 221 (7%) had no follow-up data and 336 (11%) were operated on before a planned follow-up scan was done. Of 2587 (82%) patients with follow-up data, 668 (26%) had a mass that was already in fo

BACKGROUND: There is no international consensus on how to manage women with a pregnancy of unknown location (PUL). OBJECTIVES: To present a systematic quantitative review summarising the evidence related to management protocols for PUL. SEARCH STRATEGY: MEDLINE, COCHRANE and DARE databases were searched from 01/01/1984 to 31/01/2017. The primary outcome was accurate risk prediction of women initially diagnosed with a PUL having an ectopic pregnancy (high risk) as opposed to either a failed PUL or intrauterine pregnancy ((low risk). SELECTION CRITERIA: All studies written in the English language, that were not case reports or series that assessed women classified as having a PUL at initial ultrasound. DATA COLLECTION AND ANALYSIS: Forty-three studies were included. QUADAS-2 criteria were used to assess the risk of bias. We used a novel linear mixed effects model and constructed summary receiver operating characteristic (SROC) curves for the thresholds of interest. MAIN RESULTS: There was a high risk of differential verification bias in most studies. Meta-analyses of accuracy were performed on (i) single hCG cut-off levels, (ii) hCG ratio (hCG at 48 hours / initial hCG), (iii) single progesterone cut-off levels and (iv) the 'M4 model' (a logistic regression model based on the initial hCG and hCG ratio). For predicting an ectopic pregnancy, the AUCs (95% CI) for these four management protocols were: (i) 0.42 (0.00-0.99), (ii) 0.69 (0.57-0.78), (iii) 0.69 (0.54-0.81) and (iv) 0.87 (0.83-0.91), respectively. CONCLUSIONS: The M4 model was the best available method for predicting a final outcome of ectopic pregnancy. Developing and validating risk prediction models may optimise the management of PUL.

ObjectiveTo generate guidance for detailed uterine niche evaluation by ultrasonography in the non‐pregnant woman, using a modified Delphi procedure amongst European experts.MethodsTwenty gynecological experts were approached through their membership of the European Niche Taskforce. All experts were physicians with extensive experience in niche evaluation in clinical practice and/or authors of niche publications. By means of a modified Delphi procedure, relevant items for niche measurement were determined based on the results of a literature search and recommendations of a focus group of six Dutch experts. It was predetermined that at least three Delphi rounds would be performed (two online questionnaires completed by the expert panel and one group meeting). For it to be declared that consensus had been reached, a consensus rate for each item of at least 70% was predefined.ResultsFifteen experts participated in the Delphi procedure. Consensus was reached for all 42 items on niche evaluation, including definitions, relevance, method of measurement and tips for visualization of the niche. A niche was defined as an indentation at the site of a Cesarean section with a depth of at least 2 mm. Basic measurements, including niche length and depth, residual and adjacent myometrial thickness in the sagittal plane, and niche width in the transverse plane, were considered to be essential. If present, branches should be reported and additional measurements should be made. The use of gel or saline contrast sonography was preferred over standard transvaginal sonography but was not considered mandatory if intrauterine fluid was present. Variation in pressure generated by the transvaginal probe can facilitate imaging, and Doppler imaging can be used to differentiate between a niche and other uterine abnormalities, but neither was considered mandatory.ConclusionConsensus between niche experts was achieved regarding ultrasonographic niche evaluation. © 2018 The Authors.

OBJECTIVE: To estimate the incidence of caesarean scar pregnancy (CSP) and to describe the management outcomes associated with this condition DESIGN: A national cohort study using the UK Early Pregnancy Surveillance Service (UKEPSS). SETTING: 86 participating Early Pregnancy Units. POPULATION: All women diagnosed in the participating units with CSP between November 2013 and January 2015. METHODS: COHORT STUDY OF WOMEN IDENTIFIED THROUGH THE UKEPSS MONTHLY MAILING SYSTEM: MAIN OUTCOME MEASURES: Incidence, clinical outcomes and complications. RESULTS: 102 cases of CSP were reported, with an estimated incidence of 1.5 per 10,000 (95% CI 1.1 - 1.9) maternities. Full outcome data were available for 92 women. Management was expectant in 21/92 (23%), medical in 15/92 (16%), and surgical in 56/92 (61%). The success rates of expectant, medical, and surgical management were 43% (9/21), 46% (7/15) and 96% (54/56) respectively. The complication rates were 15/21 (71%) with expectant, 9/15 (60%) with medical and 20/56 (36%) with surgical management. Discharge from care (median number of days) was 82 (range 37-174) with expectant, 21 (range 10-31) with medical, and 11 (range 4-49) with surgical management. CONCLUSIONS: Surgical management appears to be associated with a high success rate, low complication rate and short post-treatment follow up. This article is protected by copyright.

BackgroundTubal ectopic pregnancy (tEP) is the most common life-threatening condition in gynaecology. Treatment options include surgery and medical management. Stable women with tEPs with pre-treatment serum human chorionic gonadotrophin (hCG) levels < 1000 IU/L respond well to outpatient medical treatment with intramuscular methotrexate. However, tEPs with hCG > 1000 IU/L can take significant time to resolve with methotrexate and require multiple outpatient monitoring visits. In pre-clinical studies, we found that tEP implantation sites express high levels of epidermal growth factor receptor. In early-phase trials, we found that combination therapy with gefitinib, an orally active epidermal growth factor receptor antagonist, and methotrexate resolved tEPs without the need for surgery in over 70% of cases, did not cause significant toxicities, and was well tolerated. We describe the protocol of a randomised trial to assess the efficacy of combination gefitinib and methotrexate, versus methotrexate alone, in reducing the need for surgical intervention for tEPs.Methods and analysisWe propose to undertake a multi-centre, double-blind, placebo-controlled, randomised trial (around 70 sites across the UK) and recruit 328 women with tEPs (with pre-treatment serum hCG of 1000–5000 IU/L). Women will be randomised in a 1:1 ratio by a secure online system to receive a single dose of intramuscular methotrexate (50 mg/m2) and either oral gefitinib or matched placebo (250 mg) daily for 7 days. Participants and healthcare providers will remain blinded to treatment allocation throughout the trial. The primary outcome is the need for surgical intervention for tEP. Secondary outcomes are the need for further methotrexate treatment, time to resolution of the tEP (serum hCG ≤ 15 IU/L), number of hospital visits associated with treatment (until resolution or scheduled/emergency surgery), and the return of menses by 3 months after resolution.

Farren J, Mitchell-Jones N, Verbakel JY, Timmerman D, Jalmbrant M, Bourne Tet al., 2018, The psychological impact of early pregnancy loss, Human Reproduction Update, Vol: 24, Pages: 731-749, ISSN: 1355-4786

BACKGROUNDEarly pregnancy loss (EPL) is a common event, with scope for long-term personal and societal impact. There are three decades worth of published evidence of profound psychological sequelae in a significant proportion of women. However, the wide variety of outcomes, screening instruments, assessment timings and geographical locations makes it challenging to form a coherent picture of the morbidity within the whole group and its subgroups.OBJECTIVE AND RATIONALEThis review aims to investigate three questions. (1) What is the evidence for depression, anxiety and post-traumatic stress disorder (PTSD) following a miscarriage or an ectopic pregnancy in women and/or their partners? (2) What is the intensity and duration of these conditions, and how do they compare to those without losses? (3) Which patients have been found to be at highest risk of psychopathology? Answers to these questions are salient not only in day-to-day clinical interactions with those experiencing EPL, whose psychological needs may not be prioritized, but should also form the basis for tailoring healthcare policy in terms of screening for and treating the associated psychological morbidity.SEARCH METHODSThe following databases were searched, from the start of each database up to July 2017: MEDLINE (Ovid interface, 1948 onwards), Embase classic + Embase (Ovid interface, 1947 onwards), and PsychINFO (Ovid interface, 1806 onwards). Search strategies were developed using medical subject headings (MeSH). The concepts of psychological morbidity (anxiety, depression or PTSD) and pregnancy loss (miscarriage or ectopic pregnancy) were first expanded with the Boolean operator ‘or’, then linked together using ‘and’.Included studies were of prospective cohort design, including women or men following EPL (with the majority to have experienced losses before 24 weeks gestation), and reporting standardized psychometric measures for anxiety, depression and post-traumatic stress disord

OBJECTIVES: The aim is to determine if there are any ultrasound features of papillations or of the cyst wall that can discriminate between benign and malignant unilocular-solid cysts with papillations but no other solid components. METHODS: Patients with an adnexal lesion described at ultrasonography as unilocular-solid with papillations but no other solid components were identified from the International Ovarian Tumor Analysis (IOTA) database derived from seven ultrasound centers. All had undergone transvaginal ultrasonography between 1999 and 2012 by an experienced examiner following the IOTA research protocol. Information on four ultrasound features of papillations had been collected prospectively. Information on a further seven ultrasound features was collected retrospectively from electronic or paper ultrasound images of good quality. The histological diagnosis of the surgically removed adnexal lesion was the gold standard. RESULTS: Of 204 masses included, 131 (64%) were benign, 42 (20.5%) were borderline tumors, 31 (15%) primary invasive and one (0.5%) was a metastasis. Multivariate logistic regression analysis showed the following ultrasound features to be independently associated with malignancy: the height of the largest papillation, blood flow in papillations, papillation confluence or papillation dissemination, and shadows behind papillations. Shadows decreased the odds of malignancy, the other features increased them. CONCLUSION: We have identified ultrasound features that can help discriminate between benign and malignant unilocular-solid cysts with papillations but no other solid components. Our results need to be confirmed in prospective studies.

Aim: Uterine transplantation (UTx) is proposed for treatment of uterine factor infertility. Our aim was to assess whether Endoscopic Laser Speckle Contrast Analysis (eLASCA) could evaluate pelvic blood flow at anastomotic sites required for sheep and rabbit UTx. Results/methodology: eLASCA detected blood flow in rabbit UTx #7 and #9. In sheep UTx #2, #3 and #5, the results allowed us to conclude that blood flow was present in the uterine graft following transplantation; and post-UTx, the animal had heart and respiratory rates, and oxygen saturation compatible with a normal hemodynamic status. Conclusion: These preliminary results establish the potential of Laser Speckle Contrast Analysis as noncontact and real-time tool for observation of spatially-resolved blood flow from which other parameters can be derived.

Aim: We have assessed the potential predictive ability of the biomarkers activin B and fibronectin (FN1) alone and when added to established markers for triaging patients as being at low or high risk of ectopic pregnancy (EP). We also assessed their use as predictors of viability at 12 weeks gestation. Methods: Exploratory secondary analysis of a prospective study including all women classified as a pregnancy of known location (PUL) based on transvaginal ultrasonography between January and December 2007 at the early pregnancy unit of St Georges' Hospital (London). We used multinomial logistic regression to assess the diagnostic potential of the biomarkers to triage PUL at high risk of complications (EP or persistent PUL), and standard binary logistic regression to predict first trimester viability at 12 weeks. Results: For discriminating high-risk (n = 16) from low-risk PUL (n = 93), the area under the receiver operating characteristic curve (AUC) was 0.75 (95% confidence interval 0.60-0.85) for activin B and 0.55 (0.41-0.68) for FN1. Adding activin B to a multinomial logistic regression model incorporating β-hCG ratio and initial progesterone yielded odds ratios of 0.16 (0.05-0.55) for failing vs high-risk PUL and 0.29 (0.07-1.19) for intrauterine vs high-risk PUL and increased the model's AUC from 0.84 to 0.89. At a risk threshold of 5% for high-risk PUL, sensitivity increased from 84% to 87% and specificity from 48% to 64%. For discriminating viable (n = 28) from non-viable (n = 81) pregnancies at 12 weeks, both markers had an AUC of 0.54. Conclusions: Our results suggested that activin B may be a promising marker to improve PUL triage in addition to established markers.

OBJECTIVES: To describe the sonographic features of endometrial cancer in relation to stage, grade, and histological type using the International Endometrial Tumor Analysis (IETA) terminology. METHODS: Prospective multicenter study on 1714 women with endometrial cancer undergoing a standardized transvaginal grayscale and Doppler ultrasound examination by an experienced ultrasound examiner using a high-end ultrasound system. Clinical and sonographic data were entered into a web-based protocol. We assessed how strongly sonographic characteristics, according to IETA, were associated to outcome at hysterectomy, i.e. tumor stage, grade, and histological type. RESULTS: After excluding 176 women (no or delayed hysterectomy, final diagnosis other than endometrial cancer, or incomplete data), 1538 women were included in our statistical analysis. Median age was 65 years (range 27-98), and median BMI 28.4 (range 16-67), 1378 (89.7%) women were postmenopausal, and 1296 (84.2%) reported abnormal vaginal bleeding. Grayscale and color Doppler features varied according to grade and stage. High-risk tumors (stage 1A, grade 3 or non-endometrioid or ≥ stage 1B) were less likely to have regular endometrial myometrial border (difference of -23%, 95% CI -27 to -18%), whilst they were larger (mean endometrial thickness; difference of +9 mm, 95% CI +8 to +11 mm), more frequently had non-uniform echogenicity (difference of +10%, 95% CI +5 to +15%), a multiple, multifocal vessel pattern (difference of +21%, 95% CI +16 to +26%), and a moderate or high color score (difference of +22%, 95% CI +18 to +27%), than low-risk tumors. CONCLUSION: Grayscale and color Doppler ultrasound features are associated with grade and stage, and differ between high and low risk endometrial cancer.

Aim: Uterine transplantation (UTx) has been proposed as a treatment for permanent absolute uterine factor infertility. The study aims were to compare pulse oximetry and multispectral imaging (MSI), for intraoperative tracking of uterine oxygen saturation in animal UTx models (rabbit and sheep). Results/methodology: Imaging results confirmed the re-establishment of adequate perfusion in the transplanted organ after surgery. Comparison of oxygen saturation values between the pre-UTx donor and post-UTx recipient, and pre-UTx and post-UTx recipient reveals a statistically significant decrease in saturation levels post-UTx. Conclusion: The use of MSI is the first case in gynecology and has demonstrated promise of possible future human use. MSI technique has advantages over pulse oximetry - it provides spatial information in a real-time, noncontact manner.

Objective To determine whether ambulatory (outpatient (OP)) treatment of severe nausea and vomiting of pregnancy (NVP) is as effective as inpatient (IP) care.Design Non-blinded randomised control trial (RCT) with patient preference arm.Setting Two multicentre teaching hospitals in London.Participants Women less than 20 weeks’ pregnant with severe NVP and associated ketonuria (>1+).Methods Women who agreed to the RCT were randomised via web-based application to either ambulatory or IP treatment. Women who declined randomisation underwent the treatment of their choice in the patient preference trial (PPT) arm. Treatment protocols, data collection and follow-up were the same for all participants.Main outcome measures Primary outcome was reduction in Pregnancy Unique Quantification of Emesis (PUQE) score 48 hours after starting treatment. Secondary outcome measures were duration of treatment, improvement in symptom scores and ketonuria at 48 hours, reattendances within 7 days of discharge and comparison of symptoms at 7 days postdischarge.Results 152/174 eligible women agreed to participate with 77/152 (51%) recruited to the RCT and 75/152 (49%) to the PPT.Patients were initially compared in four groups (randomised IP, randomised OP, non-randomised IP and non-randomised OP). Comprehensive cohort analysis of participants in the randomised group (RCT) and non-randomised group (PPT) did not demonstrate any differences in patient demographics or baseline clinical characteristics. Pooled analysis of IP versus OP groups showed no difference in reduction in PUQE score at 48 hours (p=0.86). There was no difference in change in eating score (p=0.69), drinking score (p=0.77), well-being rating (p=0.64) or reduction in ketonuria (p=0.47) at 48 hours, with no difference in duration of index treatment episode (p=0.83) or reattendances within 7 days (p=0.52).Conclusions Ambulatory management is an effective direct alternative to IP management of s

Objective How adverse outcomes and complaints are managed may significantly impact on physician well-being and practice. We aimed to investigate how depression, anxiety and defensive medical practice are associated with doctors actual and perceived support, behaviour of colleagues and process issues regarding how complaints investigations are carried out.Design A survey study. Respondents were classified into three groups: no complaint, recent/current complaint (within 6 months) or past complaint. Each group completed specific surveys.Setting British Medical Association (BMA) members were invited to complete an online survey.Participants 95 636 members of the BMA were asked to participate. 7926 (8.3%) completed the survey, of whom 1780 (22.5%) had no complaint, 3889 (49.1%) had a past complaint and 2257 (28.5%) had a recent/current complaint. We excluded those with no complaints leaving 6144 in the final sample.Primary outcomes measures We measured anxiety and depression using the Generalised Anxiety Disorder Scale 7 and Physical Health Questionnaire 9. Defensive practice was assessed using a new measure for avoidance and hedging.Results Most felt supported by colleagues (61%), only 31% felt supported by management. Not following process (56%), protracted timescales (78%), vexatious complaints (49%), feeling bullied (39%) or victimised for whistleblowing (20%), and using complaints to undermine (31%) were reported. Perceived support by management (relative risk (RR) depression: 0.77, 95% CI 0.71 to 0.83; RR anxiety: 0.80, 95% CI 0.74 to 0.87), speaking to colleagues (RR depression: 0.64, 95% CI 0.48 to 0.84 and RR anxiety: 0.69, 95% CI 0.51 to 0.94, respectively), fair/accurate documentation (RR depression: 0.80, 95% CI 0.75 to 0.86; RR anxiety: 0.81, 95% CI 0.75 to 0.87), and being informed about rights (RR depression 0.96 (0.89 to 1.03) and anxiety 0.94 (0.87 to 1.02), correlated positively with well-being and reduc

Introduction: The objective was to validate a virtual reality simulation ultrasound model as a tool for training in the use of transvaginal ultrasonography in gynaecology and early pregnancy. Methods: Three separate groups consisting of novice and intermediate level residents as well as expert ultrasound examiners were recruited to the study. All were asked to answer a questionnaire regarding demographic data and ultrasound experience. They subsequently completed two modules: basic gynaecology and early pregnancy, followed by corresponding assessments using a high-fidelity simulator (Scantrainer; Medaphor™, Cardiff, UK). Finally, the expert group completed an additional questionnaire about various elements of the simulator using a 5-point Likert scale. Results: Each group consisted of eight participants. Overall, the participants agreed that simulation played a role in training (Novices: 75% (n = 6); Intermediates: 100% (n = 8); Experts: 75% (n = 6)). For the degree of realism of the target objects in the gynaecology and early pregnancy module environments compared to a real-patient environment, the simulator was rated satisfactory or very satisfactory by 88% (n = 7) and 75% (n = 6) of experts, respectively. All experts rated the overall usefulness of the content of the simulator for learning fundamental ultrasound technical skills compared to current training methods to be at least satisfactory. When reviewing the assessment scores, experts scored higher than non-experts in gynaecology (P = 0.002) and early pregnancy modules (P = 0.03). Discussion: Face, content and construct validity were demonstrated by the virtual reality ultrasound simulator, suggesting it may be an effective method for training ultrasound skills in gynaecology and early pregnancy to non-expert residents.
