Vaginal Swelling After Intercourse: A Case Report

Introduction: A vulvar hematoma is a hemorrhagic fluid collection in the female external genitalia. The majority occur as an obstetrical complication, especially during labor. Non-obstetrical vulvar hematomas are usually the result of trauma, with coitus being the most common etiology. Case Report: We present the case of a 25-year-old woman with significant vaginal pain and swelling after vigorous sexual intercourse. She exhibited tenderness and swelling of the left labia majora and minora. The differential diagnosis included bleeding, abscess, and deep venous thrombosis. Laboratory studies were normal and computed tomography of the pelvis indicated the swelling was most likely due to blood. The patient was taken to the operating room, and approximately 150 cubic centimeters of clot was evacuated. The patient had an uneventful recovery and was discharged home the next day. Conclusion: This case illustrates the unique presentation and challenges in making the diagnosis of vulvar hematoma.

The Emirates Mars Mission

The Emirates Mars Mission (EMM) was launched to Mars in the summer of 2020, and is the first interplanetary spacecraft mission undertaken by the United Arab Emirates (UAE). The mission has multiple programmatic and scientific objectives, including the return of scientifically useful information about Mars. Three science instruments on the mission's Hope Probe will make global remote sensing measurements of the Martian atmosphere from a large low-inclination orbit that will advance our understanding of atmospheric variability on daily and seasonal timescales, as well as vertical atmospheric transport and escape. The mission was conceived and developed rapidly starting in 2014, and had aggressive schedule and cost constraints that drove the design and implementation of a new spacecraft bus. A team of Emirati and American engineers worked across two continents to complete a fully functional and tested spacecraft and bring it to the launchpad in the middle of a global pandemic. EMM is being operated from the UAE and the United States (U.S.), and will make its data freely available.

Exploring the Patient's Experience of Receiving Clinical Care Which Incorporates the Use of Mobile Technology at the Bedside

OBJECTIVE

Research-based insight into patient's experiences of mobile technology at the bedside in the hospital setting remains limited. This research project aims to explore patient's experience.

METHODS

This mixed method pre and post study aimed to explore the patient experience in relation to this and also test whether introducing further bedside technology (beyond the workstation on wheels) had an effect on the patient experience. Questionnaires and interviews were conducted among inpatient samples prior to and one year post introduction of a suite of new bedside technologies.

RESULTS

Pre and post patient survey results (pre: n=82; post: n=98) suggested that mixed views and perceptions existed and that some of these were associated with primary demographics such as age. At post-test, attitudes about bedside technology were found to be more positive, and feedback about care quality was found to be unchanged, Baseline patient interview findings (n=15) highlight the social ubiquity of technology as a driver of positive attitude in the digital health context.

CONCLUSION

The addition of new bedside technology is very well received by patients and was not perceived to impact on care quality.

1174 The Reporting of Centre and Surgeon Experience in Studies of Robot Assisted Cholecystectomy: A Systematic Review

Introduction

Over 90% of cholecystectomies are performed using minimally invasive techniques. Robotic cholecystectomy (RC) has been developed to overcome technical limitations of laparoscopy, including improved range of movement and visualisation. Despite becoming increasingly widespread, the safety and efficacy of RC remain unestablished. This review aims to analyse the quality assurance reporting through centre and surgeon expertise in RC.

Method

A systematic search was conducted to identify all published studies reporting RC. Data on quality assurance measures were collected, including: centres involved, surgeons’ experience and training.

Results

Of the 1425 abstracts screened, 90 full-text papers were included. Sixty-four studies (71%) were single institutions. Of the thirty studies (33%) reporting centre type, 28 were conducted in specialist/regional/tertiary centres. Only four stated their caseload of RC. No studies described pre-specified criteria or minimum experience required for a surgeon to participate. Fifty-two (58%) reported the number of surgeons operating and 13 (14%) stated surgeons’ training grade. Two quantified previous RC experience, 7 stated prior laparoscopic experience. Only 21 (23%) described training prior to the surgeons’ first in-human procedure; animal based (n = 12), simulation (n = 12), observation (n = 4), lab-based (n = 3). Specific mentorship was reported in 8 studies, and 13 described dual operating.

Conclusions

Little information was provided about the experience and training of operating surgeons, making it difficult to ascertain whether replicable techniques were utilised which would allow development of a learning curve. This highlights the need for better transparency when reporting surgical innovation, to ensure the safe, evidence-based adoption of new technologies into clinical practice.

1498 A Ten-Year Observational Study of The Use of Two-Way Catheters Post-Transurethral Resection of The Prostate Without the Use of Post-Op Irrigation

Aim

To evaluate our practice of using two-way catheters without irrigation post-TURP and to determine impact on patient care compared to standard three-way catheterization. Our primary outcome was duration of admission, but multiple secondary outcomes were also analysed.

Method

This was a prospective observational study. Every patient undergoing TURP at our centre from 2009 to 2019 was included. Prospective patient data were collected pertaining to peri-operative factors. This data was then compared with data published in the NICE guidance pertaining to TURP.

Results

687 patients underwent TURP at our centre between 2009-2019. The average age of patients was 71.42 (±7.89). 87.17% (n = 598) had two-way catheters placed post-operatively. Average duration of admission was 1.61 (±1.35) days. TWOC was successful in 93.74% (n = 644). Complication rate was 8.73% (n = 60), reduced in comparison to other units. Furthermore, when compared to other centres, our method reduced lengths of admission and transfusion rates (1.6 days vs. 3.1 days and 0.87% vs. 2.83% respectively).

Conclusions

Our method preserves patient safety and is associated with reduced length of admission. It also has cost-saving benefits and a reduced post-operative period of catheterisation. We recommend this practice to the wider urological community.

Modified conventional gait model vs. Six degrees of freedom model: A comparison of lower limb kinematics and associated error

BACKGROUND

The conventional gait model (CGM) is commonly utilised within clinical motion analysis but has a number of inherent limitations. To overcome some of these limitations modifications have been made to the CGM and six-degrees of freedom models (6DoF) have been developed.

RESEARCH QUESTION

How comparable are lower limb kinematics calculated using modified CGM and 6DoF models and what is the error associated with the output of each model during walking?

METHODS

Ten healthy males attended two gait analysis sessions, in which they walked at a self-selected pace, while a 10-camera motion capture system recorded lower limb kinematics. Hip, knee and ankle joint kinematics in all three anatomical planes were calculated using a modified CGM, with medial anatomical markers and a three-dimensional foot added, and 6DoF. Mean absolute differences were calculated on a point-by-point basis over the walking gait cycle and interpreted relative to a 5° threshold to explore the comparability of model outputs. The standard error of the measurement (SEM) was also calculated on a point-by-point basis over the walking gait cycle for each model.

RESULTS

Mean absolute differences above 5° were reported between the two model outputs in 58-86% of the walking gait cycle at the knee in the frontal plane, and over the entire walking gait cycle at the hip and knee in the transverse plane. SEM was typically larger for the modified CGM compared to the 6DoF, with the highest SEM values reported at the knee in the frontal plane, and the hip and the knee in the transverse plane.

SIGNIFICANCE

Caution should be taken when looking to compare findings between studies utilising modified CGM and 6DoF outside of the sagittal plane, especially at the hip and knee. The reduced SEM associated with the 6DoF suggests this modelling approach may be preferable.

Surface color spectrophotometry in a murine model of steatosis: an accurate technique with potential applicability in liver procurement

Steatosis is the most important prognostic histologic feature in the setting of liver procurement. The currently utilized diagnostic methods, including gross evaluation and frozen section examination, have important shortcomings. Novel techniques that offer advantages over the current tools could be of significant practical utility. The aim of this study is to evaluate the accuracy of surface color spectrophotometry in the quantitative assessment of steatosis in a murine model of fatty liver. C57BL/6 mice were divided into a control group receiving normal chow (n = 19), and two steatosis groups receiving high-fat diets for up to 20 weeks-mild steatosis (n = 10) and moderate-to-severe steatosis (n = 19). Mouse liver surfaces were scanned with a hand-held spectrophotometer (CM-600D; Konica-Minolta, Osaka, Japan). Spectral reflectance data and color space values (L*a*b*, XYZ, L*c*h*, RBG, and CMYK) were correlated with histopathologic steatosis evaluation by visual estimate, digital image analysis (DIA), as well as biochemical tissue triglyceride measurement. Spectral reflectance and most color space values were very strongly correlated with histologic assessment of total steatosis, with the best predictor being % reflectance at 700 nm (r = 0.91 [0.88-0.94] for visual assessment, r = 0.92 [0.88-0.95] for DIA of H&E slides, r = 0.92 [0.87-0.95] for DIA of oil-red-O stains, and r = 0.78 [0.63-0.87] for biochemical tissue triglyceride measurement, p < 0.0001 for all). Several spectrophotometric parameters were also independently predictive of large droplet steatosis. In conclusion, hepatic steatosis can accurately be assessed using a portable, commercially available hand-held spectrophotometer device. If similarly accurate in human livers, this technique could be utilized as a point-of-care tool for the quantitation of steatosis, which may be especially valuable in assessing livers during deceased donor organ procurement.

POS0492 A MOLECULAR SIGNATURE RESPONSE CLASSIFIER PREDICTS THE LIKELIHOOD OF EULAR NON-RESPONSE TO TNF INHIBITOR THERAPIES IN RA: RESULTS FROM A RETROSPECTIVE COHORT ANALYSIS

Background:

Following RA treatment recommendations, most people with rheumatoid arthritis (RA) begin targeted therapy with TNF inhibitors (TNFi), even though inadequate response to TNFi therapies is widespread. Treatment changes from one medication to the next are currently fueled by disease-activity measures and eventually result in disease control for most patients; however, this “trial-and-error” approach wastes precious time on ineffective treatments. A delay in reaching treat-to-target goals has a negative effect on patient burden and, possibly, disease progression.1 Useful predictors for TNFi response have been challenging to identify but a specific molecular signature response classifier (MSRC) test was shown to be predictive for inadequate response to TNFi therapies.2 The impact of such identification has the potential to result in improved patient outcomes, but further validation would be welcome, especially for response criteria other than ACR50, and in a stringent treat-to-target setting with lower baseline disease activity.

Objectives:

To validate the predictive value of the MSRC test in identifying those patients who do not meet EULAR good response criteria after 6 months of TNFi treatment.

Methods:

Data from a prospective cohort study conducted in the Sint Maartenskliniek (Nijmegen, the Netherlands) of RA patients who started adalimumab or etanercept TNFi as their first biologic were included.3 Baseline RNA samples and clinical assessments were used to identify patients who had a molecular signature1 of non-response to TNFi therapy. Outcomes were calculated at six months using DAS28-CRP-based EULAR good response, and high and low confidence responders and non-responders were identified using Monte Carlo simulation with 2,000 repeats and 70% precision cut off. Outcome measurements were blinded for test results. Treatment switch before 6 months was imputed as non-response. Odds ratios and area under the ROC curve (AUC) assessments were used to evaluate the ability of the MSRC test to predict inadequate response at 6 months against EULAR good response criteria.

Results:

A total of 68 out of 88 RA patients were identified to have a high-confidence response status and were included in analyses (Table 1). EULAR good response was observed in 45.5% (31/68) of patients. Patients were stratified according to detection of a molecular signature of non-response with an AUC of 0.61. The odds that a patient with the molecular signature of non-response at baseline failed to achieve a EULAR good response at 6 months was four times greater than that of a patient lacking the molecular signature (odds ratio 4.0, 95% confidence interval 1.2-13.3).

Table 1.

Patient demographics

CharacteristicRA patients (N = 68)Age, median (SD)57 (11)Female, n (%)43 (63.2)CCP positive, n (%)34 (50.0)RF positive, n (%)38 (55.9)Prescribed adalimumab at baseline, n (%)11 (16.2)Prescribed etanercept at baseline, n (%)57 (83.8)

Conclusion:

In this validation study, the molecular signature of non-response identified patients who did not fulfill the EULAR good response criteria to TNFi therapies. The patient selection process for this study had limitations; additional analysis in an alternative cohort would further verify the performance of the MSRC test. Nevertheless, the test, previously validated for ACR50, now has been validated using EULAR good response in a treat-to-target setting.

AB0140 A HIGH-CONFIDENCE DEFINITION OF THERAPEUTIC RESPONSE IN RHEUMATOID ARTHRITIS USING A MONTE CARLO SIMULATION APPROACH

Background:

Therapy choice and therapy change depend on the ability to accurately assess patients’ disease activity. The clinical assessments used to evaluate treatment response in rheumatoid arthritis have inherent variability, normally considered as measurement error, intra-observer variability or within subject variability. Each contribute to variability in deriving response status as defined by composite measures such as the ACR or EULAR criteria, particularly when a one-time observed measurement lies near the boundary defining response or non-response. To select an optimal therapeutic strategy in the burgeoning age of precision medicine in rheumatology, achieve the lowest disease activity and maximize long-term health outcomes for each patient, improved treatment response definitions are needed.

Objectives:

Develop a high-confidence definition of treatment response and non-response in rheumatoid arthritis that exceeds the expected variability of subcomponents in the composite response criteria.

Methods:

A Monte Carlo simulation approach was used to assess ACR50 and EULAR response outcomes in 100 rheumatoid arthritis patients who had been treated for 6 months with a TNF inhibitor therapy. Monte Carlo simulations were run with 2000 iterations implemented with measurement variability derived for each clinical assessment: tender joint count, swollen joint count, Health Assessment Questionnaire disability index (HAQ-DI), patient pain assessment, patient global assessment, physician global assessment, serum C-reactive protein level (CRP) and disease activity score 28-joint count with CRP.1-3 Each iteration of the Monte Carlo simulation generated one outcome with a value of 0 or 1 indicating non-responder or responder, respectively.

Results:

A fidelity score, calculated separately for ACR50 and EULAR response, was defined as an aggregated score from 2000 iterations reported as a fraction that ranges from 0 to 1. The fidelity score depicted a spectrum of response covering strong non-responders, inconclusive statuses and strong responders. A fidelity score around 0.5 typified a response status with extreme variability and inconclusive clinical response to treatment. High-fidelity scores were defined as >0.7 or <0.3 for responders and non-responders, respectively, meaning that the simulated clinical response status label among all simulations agreed at least 70% of the time. High-confidence true responders were considered as those patients with high-fidelity outcomes in both ACR50 and EULAR outcomes.

Conclusion:

A definition of response to treatment should exceed the expected variability of the clinical assessments used in the composite measure of therapeutic response. By defining high-confidence responders and non-responders, the true impact of therapeutic efficacy can be determined, thus forging a path to development of better treatment options and advanced precision medicine tools in rheumatoid arthritis.

OP0090 CLASSIFICATION OF PATIENTS WITH RELAPSING POLYCHONDRITIS BASED ON SOMATIC MUTATIONS IN UBA1

Background:

Somatic mutations in ubiquitin activating enzyme 1 (UBA1) cause a newly defined syndrome known as VEXAS. [1] More than fifty percent of patients currently identified with VEXAS meet diagnostic criteria for relapsing polychondritis (RP).

Objectives:

To determine the prevalence VEXAS within a cohort of patients with RP, to compare their clinical, laboratory, and immunologic features and to develop a clinical algorithm to inform genetic screening for VEXAS among patients with RP.

Methods:

Exome and targeted sequencing of the UBA1 gene was performed in a prospective observational cohort of patients with RP. Clinical and immunological characteristics of patients with RP were compared based on presence or absence of UBA1 mutations. Random forest was used to derive a clinical algorithm to identify patients with UBA1 mutations. Immune populations were quantified by multipanel flow cytometry. Categorical and continuous variables were compared using the chi square or Kruskal-Wallis test. P<0.05 defined statistical significance.

Results:

Seven of 92 patients with RP (7.6%) were confirmed to have UBA1 mutations (VEXAS-RP). Six additional patients with VEXAS-RP from other cohorts were included for subsequent analyses. Patients with VEXAS-RP were all male, older at disease onset, and commonly had fever, ear chondritis, skin involvement, deep vein thrombosis, and pulmonary infiltrates. Patients with RP as compared with VEXAS-RP had a significantly higher prevalence of airway chondritis, costochondritis and tenosynovitis/arthralgias. (Table). Mortality was significantly greater in VEXAS-RP than RP (27% vs 2% p=0.01). Maximum ESR, CRP, and mean corpuscular volume (MCV) values were significantly greater in VEXAS-RP. Absolute monocyte, lymphocyte, and platelet counts were significantly lower in VEXAS-RP. A decision tree based on male sex, MCV>100 fl and Platelet count<200 K/ul classified between VEXAS-RP and RP with 100% sensitivity and 96% specificity.

Conclusion:

Mutations in UBA1 are causal for disease in a subset of patients with RP. These patients are defined by disease onset in the fifth decade of life or later, male sex, ear/nose chondritis and hematologic abnormalities. Early identification is important in VEXAS given the associated high mortality rate.

615 Achieving Net Zero Emission by 2050 – The Medical Education Route

Introduction

There is growing demand to reduce the environmental impact of surgery. Healthcare sustainability has recently become a mandatory GMC learning outcome for undergraduates, but expertise amongst faculty and time within the curriculum are limited. We piloted an E-module that uses surgical case studies to teach these concepts.

Method

Evidenced-based multi-media learning principles were used to develop the module. 3rd and 4th year students at Brighton and Sussex Medical School were invited to partake and complete pre- and post-module questionnaires comprising 5-point Likert scales and white-space questions. The primary outcome measures were changes in student-reported understanding of four key concepts:

Environmental impact of healthcare

Influence of climate change on health.

Principles of sustainable clinical practice.

Health co-benefits of climate change mitigation.

Results

33 students completed the E-module. Questionnaire results indicated a significant increase in understanding of all key concepts (p &lt; 0.001). Students most commonly rated improving sustainability of healthcare as ‘extremely important’. Common themes within white space responses included the importance of preventative medicine and that the module was informative, interactive, user-friendly, and engaging. The majority (81%) strongly agreed that all undergraduates should undertake this module.

Conclusions

This E-module is an effective and COVID-19-safe resource. Adapting this module for postgraduate surgical education should be explored.

138 We Tried This At Home – Safety Analysis and Outcome of Community Resource Services

Introduction

There are several data sets published for acute frailty services in hospital but there is a lack of supporting data in the emerging field of Intermediate Care. Gwent has well-established Community Resource Teams (CRT) that were set up as “Hospital at Home” services. The objective being to treat frail, acute or sub-acute medically ill patients in their own environment by a consultant-led hospital-like team using a Comprehensive Geriatric Assessment. Although “Hospital at Home” services are often preferred by the patient and are in-line with Health board strategies “Care Closer to home” and “Clinical Futures”; it is important to ask ourselves whether we are able to deliver clinical care in the community safely?

Method

One year of data from 2018 was extracted from the CRT Portal, analysed and then validated by the health board’s performance teams. From the established data set, origin of referrals and discharge outcomes were identified. Finally, at 28 days of discharge from Gwent CRTs mortality and hospital admission rates were examined.

Results

4,308 out of 5,395 referrals (85%) were accepted to Gwent CRTs of which 59.60% (2,863) referrals were from primary care and 33.54% (1,445) were from secondary care. Our admission rates to secondary care services were 15.27% (658) whilst mortality rate was 3.92% (169). After successful medical management from Gwent CRTs of 3,481 patients in their own place of residence, 28 day hospital admission rate was 13.84% (482) whilst 28 day mortality rate (expected and unexpected) was 6.89% (240).

Conclusion

Although no equivalent data is currently available for comparison, a significant number of patients can be medically managed in their own place of residence. More than 80% of patients did not require hospital admission whilst mortality rates were encouraging. Further future re-evaluation of our service performance and its value is required.
