The role of contrast-enhanced mammography in the preoperative evaluation of invasive lobular carcinoma of the breast. Clin Radiol 2024; 79:e799-e806. [PMID: 38383254 DOI: 10.1016/j.crad.2024.01.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 01/22/2024] [Accepted: 01/25/2024] [Indexed: 02/23/2024]
Abstract
AIM To assess the performance of contrast-enhanced mammography (CEM) in the preoperative staging of invasive lobular carcinoma (ILC) of the breast. MATERIALS AND METHODS The present study was a multicentre, multivendor, multinational retrospective study of women with a histological diagnosis of ILC who had undergone CEM from December 2013 to December 2021. Index lesion size and multifocality were recorded for two-dimensional (2D) mammography, CEM, and when available magnetic resonance imaging (MRI). Comparison with histological data was undertaken for women treated by primary surgical excision. Pearson correlation coefficients and Bland-Altman's analysis of agreement were used to assess differences with a significance level of 0.05. RESULTS One hundred and fifteen ILC lesions were included, 46 (40%) presented symptomatically and 69 were screening detected. CEM demonstrated superior sensitivity when compared to standard mammography. The correlation between the histological size measured on the surgical excision specimen size was greater than with standard mammography (r=0.626 and 0.295 respectively, p=0.001), with 19% of lobular carcinomas not visible without a contrast agent. The sensitivity of CEM for multifocal disease was greater than standard mammography (70% and 20% respectively, p<0.0001). CEM overestimated tumour size by an average of 1.5 times, with the size difference increasing for larger tumour. When MRI was performed (n=22), tumour size was also overestimated by an average of 1.3 times. The degree of size overestimation was similar for both techniques, with the tumour size on CEM being on average 0.5 cm larger than MRI. CONCLUSION CEM is a useful tool for the local staging of lobular carcinomas and could be an alternative to breast MRI.

Increasing Realism and Variety of Virtual Patient Dialogues for Prenatal Counseling Education Through a Novel Application of ChatGPT: Exploratory Observational Study. JMIR MEDICAL EDUCATION 2024; 10:e50705. [PMID: 38300696 PMCID: PMC10870212 DOI: 10.2196/50705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 10/18/2023] [Accepted: 12/11/2023] [Indexed: 02/02/2024]
Abstract
BACKGROUND Using virtual patients, facilitated by natural language processing, provides a valuable educational experience for learners. Generating a large, varied sample of realistic and appropriate responses for virtual patients is challenging. Artificial intelligence (AI) programs can be a viable source for these responses, but their utility for this purpose has not been explored. OBJECTIVE In this study, we explored the effectiveness of generative AI (ChatGPT) in developing realistic virtual standardized patient dialogues to teach prenatal counseling skills. METHODS ChatGPT was prompted to generate a list of common areas of concern and questions that families expecting preterm delivery at 24 weeks gestation might ask during prenatal counseling. ChatGPT was then prompted to generate 2 role-plays with dialogues between a parent expecting a potential preterm delivery at 24 weeks and their counseling physician using each of the example questions. The prompt was repeated for 2 unique role-plays: one parent was characterized as anxious and the other as having low trust in the medical system. Role-play scripts were exported verbatim and independently reviewed by 2 neonatologists with experience in prenatal counseling, using a scale of 1-5 on realism, appropriateness, and utility for virtual standardized patient responses. RESULTS ChatGPT generated 7 areas of concern, with 35 example questions used to generate role-plays. The 35 role-play transcripts generated 176 unique parent responses (median 5, IQR 4-6, per role-play) with 268 unique sentences. Expert review identified 117 (65%) of the 176 responses as indicating an emotion, either directly or indirectly. Approximately half (98/176, 56%) of the responses had 2 or more sentences, and half (88/176, 50%) included at least 1 question. More than half (104/176, 58%) of the responses from role-played parent characters described a feeling, such as being scared, worried, or concerned. The role-plays of parents with low trust in the medical system generated many unique sentences (n=50). Most of the sentences in the responses were found to be reasonably realistic (214/268, 80%), appropriate for variable prenatal counseling conversation paths (233/268, 87%), and usable without more than a minimal modification in a virtual patient program (169/268, 63%). CONCLUSIONS Generative AI programs, such as ChatGPT, may provide a viable source of training materials to expand virtual patient programs, with careful attention to the concerns and questions of patients and families. Given the potential for unrealistic or inappropriate statements and questions, an expert should review AI chat outputs before deploying them in an educational program.

Impact of the COVID-19 pandemic on a post-mortem CT service for adult non-suspicious death. Clin Radiol 2023; 78:822-831. [PMID: 37827592 DOI: 10.1016/j.crad.2023.03.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 03/14/2023] [Accepted: 03/23/2023] [Indexed: 10/14/2023]
Abstract
Due to the COVID-19 pandemic, the post-mortem computed tomography (PMCT) service was expanded from three to seven cases per day to help mortuary services and avoid invasive autopsy. Additional targeted angiography and pulmonary ventilation procedures were stopped and triage rules relaxed to allow more indications to be scanned, including those requiring toxicology. A service evaluation was performed for the first 3-months of the COVID-19 pandemic compared to the equivalent period the previous year to study the impact of these changes. It was found that, despite the increase in deaths regionally, coronial referrals remained about 100 per month, a reduction in referral rate. The number undergoing PMCT rose from 28% to 74% of cases. Turnaround time remained the same. For cases triaged to PMCT, the need for subsequent autopsy increased from 7.9% to 15.8%. No significant changes were seen in diagnosis rates, including cardiac or respiratory. There was an increase in patients with coronary death without severe coronary calcification who underwent autopsy after PMCT. These may have been diagnosed by targeted coronary angiography. Fifty-three cases requiring toxicology/biochemistry had PMCT, with 38 having PMCT only. In 8/11 (72.7%) cases with normal PMCT and toxicology as the key diagnostic test, autopsy was performed prior to results. This suggests the pathology team were reluctant to risk an "unascertained" outcome. This study shows that it is possible to increase PMCT services by widening referral criteria and by limiting the use of enhanced imaging techniques, without significantly changing diagnosis rates of key diseases; however, selectively restarting targeted angiography may help avoid autopsy in some cases.

Abstract
Background The Avoidant Restrictive Food Intake Disorder Genes and Environment (ARFID-GEN) study is a study of genetic and environmental factors that contribute to risk for developing ARFID in children and adults. Methods A total of 3,000 children and adults with ARFID from the United States will be included. Parents/guardians and their children with ARFID (ages 7 to 17) and adults with ARFID (ages 18+) will complete comprehensive online consent, parent verification of child assent (when applicable), and phenotyping. Enrolled participants with ARFID will submit a saliva sample for genotyping. A genome-wide association study of ARFID will be conducted. Discussion ARFID-GEN, a large-scale genetic study of ARFID, is designed to rapidly advance the study of the genetics of eating disorders. We will explicate the genetic architecture of ARFID relative to other eating disorders and to other psychiatric, neurodevelopmental, and metabolic disorders and traits. Our goal is for ARFID to deliver "actionable" findings that can be transformed into clinically meaningful insights. Trial registration ARFID-GEN is a registered clinical trial: clinicaltrials.gov NCT05605067.

Abstract
OBJECTIVES Long COVID can significantly impact a patient's quality of life. Defined as persistence or emergence of symptoms 4+ weeks after initial COVID-19 diagnosis, long COVID can result in functional impairments, pulmonary issues, and neuropsychiatric conditions, among others. This study aims to identify long COVID risk factors and prevalence in a south Alabama (US) patient population. STUDY DESIGN This was a longitudinal cohort study. METHODS Postdiagnosis standardized phone interviews (baseline, 6 months, and 12 months) from April 2020 to July 2021 with patients testing positive through a large healthcare system. Interviews gathered data on sociodemographics, comorbidities, acute illness, and long COVID. Relationships between 1+ ongoing symptoms and variables of interest were assessed using a generalized estimating equation to conduct multivariate analysis. RESULTS Of the 516 participants, most were female (65%) and African American (57%, n = 293), with a median (interquartile range) age of 41.1 (25.3-54.6) years. Retention was 70% (n = 359) at 6 months and 58% (n = 301) at 12 months. Participants reporting 1+ persistent symptoms were 20% and 17% at 6 and 12 months, respectively. Illness severity (P < 0.0001) and COVID-related emergency room visit with hospital admission at the time of diagnosis (P = 0.0018) were significantly associated with increased long COVID risk. CONCLUSIONS This study found substantial rates of long COVID within our population, with stable rates at 6 and 12 months, indicating illness persistence. Our findings support growing concern for long COVID as a persistent issue within the medical community, with potential to impact patient health for years. Larger, more uniform studies are required to further characterize disease risk factors and clinical course to inform the disease management.

Abstract
OBJECTIVE The objective of this program evaluation was to describe the outcomes of daily neonatologist telerounding with the onsite Advanced Practice Provider (APP) in a Level II NICU, before and during the COVID-19 pandemic. STUDY DESIGN Bedside telerounding occurred with an onsite APP using a telehealth cart and paired Bluetooth stethoscope. Data collected by longitudinal and cross-sectional surveys and chart review before (May 2019-February 2020) and during (March 2020-February 2021) the COVID-19 pandemic were analyzed using descriptive statistics and thematic analysis. RESULTS A total of 258 patients were admitted to the Level II NICU before (May 2019-Feb 2020) and during (March 2020-Feb 2021) the COVID-19 pandemic. Demographic characteristics and outcomes, including breastfeeding at discharge and length of stay were similar pre and post-onset of the COVID-19 pandemic. Post-rounding surveys by 10 (response rate 83%) neonatologists indicated parents were present in 80 (77%) of rounds and video was at least somewhat helpful in 94% of cases. Cross-sectional survey responses of 23 neonatologists and APPs (response rate 62%) indicated satisfaction with the program. Common themes on qualitative analysis of open-ended survey responses were "need for goodness of fit", and "another set of eyes" and "opportunities for use". CONCLUSION Daily telerounding with neonatologists and APPs in a Level II NICU supported neonatal care. Quality metrics and clinical outcomes are described with no differences seen before and during the COVID-19 pandemic.

'Breast Cosmesis After Breast-Conserving Therapy' Who is the Judge, Patient or Surgeon? World J Surg 2022; 46:3051-3061.

Abstract
INTRODUCTION More than 80% of newly diagnosed breast cancers are managed with breast-conserving therapy (BCT). Preservation of cosmetically acceptable breasts is an inherent aim of all breast-conserving efforts-this can, however, be difficult to assess objectively. Compounding this is the difference in perception of breast cosmesis between patients and surgeons. This study compares the concordance of a new subscale-based cosmetic score (TCS) with the patient's perception. METHOD Eastern Health Breast and Cancer Centre conducted this study on patients who had completed their BCT and radiotherapy. Participation was voluntary and involved permitting an assessor (breast surgery fellow or consultant) to grade cosmetic outcomes to generate a Total Cosmesis Score (TCS). The patients blinded to this assessment were then asked to complete the postoperative segment of the BCT module of the Breast-Q questionnaire. TCS from surgeon assessment was compared against patient assessment (questions BQ1i and BQ1k specifically). Cohen's kappa was calculated to define the strength of the inter-rater agreement. RESULTS One hundred twelve patients with a mean age of 59 (range 27-89) participated in the study. TCS was low in 26% and high in 74% of participants. 76% and 69% of participants were satisfied when answering Breast-Q questions 'How your lumpectomy breast looks?' and 'How you look in the mirror unclothed?' respectively (Cohen's k = 0.464, 95% CI 0.337-0.591, p < 0.01). The agreement between the TCS and the patient assessment was poor (Cohen's k = 0.172, 95% CI - 0.020-2.093, p = 0.067). CONCLUSION Cosmetic outcomes scored using TCS by surgeons do not match patient's own assessment of the cosmetic result.

Abstract
Abstract
Aim
Estimates suggest that 20% of patients admitted to hospital undergo catheterisation, some of whom will end up discharged with catheters. Clear documentation assists in communication between hospital and community teams. The EAUN has identified key areas for documentation including use of care plans. We audited compliance with documentation pre- and post-intervention in a tertiary urology department
Method
Emergency patients presenting to urology were identified over a 3-week period pre-intervention and 3-weeks post-intervention. Clinical notes were audited for documentation of catheterisation. Domains assessed included indication, type/size of catheter, catheter balloon volume, residual volume, urinalysis, and plan. Use of care plans was also audited. Intervention involved development and deployment of a poster as well as discussion with staff.
Results
In total 274 patients were identified. 47 catheters were inserted pre-intervention, with variable compliance in documentation throughout the domains with similar pattern of compliance noted in the post-intervention group (n=42). Compliance was highest in size of catheter and indication for insertion, with urinalysis the most frequently missed domain (14.9% pre-intervention, 9.5% post-intervention). The only area with significant improvement was documentation of balloon volume (p=0.0019). Use of the care plan showed some minor improvement but was generally poor.
Conclusion
Use of visual cues did not result in approvement in documentation. Discussion with the teams suggested awareness of the domains and care plan however, they didn't necessarily think of them at time of documentation. As such a text prompt for the electronic notes is now in development and further audit to assess impact pending.

Abstract
Levetiracetam is a new generation antiseizure medication which binds to synaptic vesicle protein SV2A and inhibits the release of neurotransmitters. Gingival hyperplasia is a common side effect of conventional antiseizure medications like phenytoin, but very rare with the newer ones. A 14-year-old boy was started on levetiracetam 250 mg twice daily after a generalized seizure. Five days later he presented with gingival swelling and painful oral aphthae, without lymphadenopathy or systemic symptoms. Blood investigations were normal. After one-month of stopping the drug, the lesions cleared. This case highlights the importance of maintaining good oral hygiene and periodic dental review in patients on antiseizure medications.

Abstract
INTRODUCTION A recent Association of Breast Surgery summary statement on fibroadenoma management recommends excision only for cellular fibroepithelial lesions and rapidly growing lesions with a core biopsy diagnosis of fibroadenoma; persistent pain is a relative indication for excision. METHODS This retrospective study looked at the impact this approach would have on the diagnosis of phyllodes tumours. RESULTS From 2014 to 2018, there were 1,058 core biopsy diagnoses of fibroadenoma; 112 lesions were excised, of which 98 were fibroadenomas, 4 were hamartomas and 10 were phyllodes tumours. In this group, an excision diagnosis of phyllodes tumour was associated with size more than 40 mm, age more than 40 years and radiological suspicion of phyllodes tumour or carcinoma. One hundred and sixty-six excised fibroepithelial lesions with no previous core biopsy included eight phyllodes tumours; in this group, rapid growth was associated with phyllodes tumour diagnosis. Twelve of the 26 fibroepithelial lesions classified as B3 (cellular fibroepithelial lesion or phyllodes tumour) were diagnosed as phyllodes tumours on excision. Using a combination of radiological, clinical and pathological features it was possible to create an excision policy that would recommend excision of 22 of the 31 phyllodes tumours in this period. Eight of the nine 'missed' phyllodes tumours were benign. CONCLUSION The Association of Breast Surgery summary statement will reduce the number of fibroadenomas excised, but may also result in delayed diagnosis of some phyllodes tumours. Appropriate safety netting advice should be provided to identify rapidly growing lesions.

Abstract
Abstract
Introduction
Recurrence rate of surgically treated localised renal cell carcinoma (RCC) is reported to be approximately 20%. There is lack of consensus on the optimal surveillance regimen. We assess the performance of our surveillance protocol based upon prognostic histological factors. We report the outcome of our first cohort to reach 5 years follow up.
Method
A retrospective analysis was performed of patients who underwent a radical or partial nephrectomy between March 2014 and October 2015. Patients were classified as high, intermediate, or low risk based on pathology; with each group undergoing individualised radiological follow up.
Results
80 patients with pathologically confirmed RCC who underwent partial or radical nephrectomy were identified. Recurrence was noted in 24% (n = 19), and a third of those patients (n = 7) died within the 5-year follow-up period. 79% (n = 15) of patients with recurrence were of intermediate or high-risk group. 90% of recurrences were picked up on surveillance scans, 5% due to symptoms related to the recurrence and 5% incidentally. 70% occurred within the first 2 years post-surgery. 92% (n = 6) of those who died had an ASA of 2 or higher. In the whole cohort, total number of deaths was 13. 38% (n = 5) died of RCC, 54% (n = 7) died of other causes and in 8% (n = 1) cause of death of was unclear.
Conclusions
Our risk stratified surveillance protocol identified 90% of recurrences within the 5-year follow-up. Future refinement of our protocol could include an assessment of performance status which may influence the schedule of radiological surveillance.

Abstract
In the UK, women between 50-70 years are invited for 3-yearly mammography screening irrespective of their likelihood of developing breast cancer. The only risk adaption is for women with >30% lifetime risk who are offered annual magnetic resonance imaging (MRI) and mammography, and annual mammography for some moderate-risk women. Using questionnaires, breast density, and polygenic risk scores, it is possible to stratify the population into the lowest 20% risk, who will develop <4% of cancers and the top 4%, who will develop 18% of cancers. Mammography is a good screening test but has low sensitivity of 60% in the 9% of women with the highest category of breast density (BIRADS D) who have a 2.5- to fourfold breast cancer risk. There is evidence that adding ultrasound to the screening mammogram can increase the cancer detection rate and reduce advanced stage interval and next round cancers. Similarly, alternative tests such as contrast-enhanced mammography (CESM) or abbreviated MRI (ABB-MRI) are much more effective in detecting cancer in women with dense breasts. Scintimammography has been shown to be a viable alternative for dense breasts or for follow-up in those with a personal history of breast cancer and scarring as result of treatment. For supplemental screening to be worthwhile in these women, new technologies need to reduce the number of stage II cancers and be cost effective when tested in large scale trials. This article reviews the evidence for supplemental imaging and examines whether a risk-stratified approach is feasible.

Abstract
BACKGROUND Intranasal corticosteroids are widely used for management of many upper airway diseases because of their ability to effectively deliver local relief of inflammation. CASE REPORT This paper presents the case of a 51-year-old man with human immunodeficiency virus treated with ritonavir who was started on fluticasone intranasal spray for presumed chronic rhinosinusitis. Months after starting this therapy, he developed symptoms of Cushing's syndrome and avascular necrosis of the shoulder due to the pharmacological interactions between fluticasone and ritonavir. CONCLUSION Although intranasal corticosteroids are deemed a low-risk route of drug administration, clinicians need to be vigilant in appropriately prescribing corticosteroids in the setting of drug potentiators, particularly in these high-risk patients. Alternative corticosteroids such as beclomethasone dipropionate should be considered in such cases.

Abstract
This study investigates the potential of a blended binder formulated from two industrial solid wastes viz. phosphogypsum and fly ash in combination with lime. Three mix proportions of phosphogypsum and fly ash were investigated, and the minimum lime contents required for activation were determined using the Eades and Grim pH test. The lime-fly ash-phosphogypsum blends were then cast into cubes, both in their paste form as well as mortar form, mixed with sand in the ratio of 1:3. They were cured for a period of seven days, and afterwards, their compressive strength was determined. Ordinary Portland cement and lime mortar blocks were also cast as control specimens for comparative evaluation of the strength. The optimal lime-fly ash-phosphogypsum blend was identified and used to construct a masonry prism, and the strengths of the masonry prisms were also evaluated. The optimal lime-fly ash-phosphogypsum blend mortar was also subjected to an X-ray diffraction analysis to determine the reaction products formed during hydration. The study revealed that 5% lime mixed with fly ash:phosphogypsum in the ratio of 3:1 was the optimal proportion which gave the maximum strength to the cubes. The optimal lime-fly ash-phosphogypsum blend mortar developed strength that was higher than conventional Portland cement and lime mortar. The optimal lime-fly ash-phosphogypsum blend mortar masonry prisms developed strength that was comparable to that of Portland cement mortar masonry. The X-ray diffraction analysis revealed the formation of calcium silicate hydrate minerals as well as ettringite and portlandite which were responsible for strength gain.

Highly pathogenic avian influenza virus H5N6 (clade 2.3.4.4b) has a preferable host tropism for waterfowl reflected in its inefficient transmission to terrestrial poultry. Virology 2021; 559:74-85.

Abstract
Highly-pathogenic avian influenza virus (HPAIV) H5N6 (clade 2.3.4.4b) incurred into Europe in late 2017 and was predominantly detected in wild birds, with very few terrestrial poultry cases. Pekin ducks directly-infected with a UK virus (H5N6-2017) were donors of infection to investigate contact transmission to three recipient species: Ducks, chickens and turkeys. H5N6-2017 transmission to ducks was 100% efficient, but transmission to in-contact galliforme species was infrequent and unpredictable, thereby reflecting the European 2017-2018 H5N6 epidemiology. Although only two of 28 (7%) infected ducks died, the six turkeys and one chicken which became infected all died and displayed systemic H5N6-2017 dissemination, while pathogenesis in ducks was generally milder. Analysis of H5N6-2017 progeny in the contacts revealed no emergent polymorphisms in an infected duck, but the galliforme species included changes in the polymerase (PB2 A199T, PA D347A), matrix (M1 T218A) and neuraminidase genes (T88I). H5N6-2017 environmental contamination was associated with duck shedding.

Abstract
People with diabetes account for nearly one-fifth of all inpatients in English and Welsh hospitals; of these, up to 90% are admitted as an emergency. Most are admitted for a reason other than diabetes with only 8% requiring admission for a diabetes-specific cause. Healthcare professionals working in emergency departments experience numerous clinical challenges, notwithstanding the need to know whether each individual with diabetes requires urgent admission. This document has been developed and written by experts in the field, and reviewed by the parent organizations of the Joint British Diabetes Societies for Inpatient Care-Diabetes UK, the Diabetes Inpatient Specialist Nurse Group and the Association of British Clinical Diabetologists. The document aims to support staff working in emergency departments and elsewhere by offering practical advice and tools for effective, appropriate and safe triage. Each section relates to the commonest diabetic specific emergencies and algorithms can be printed off to enable ease of access and use.

Abstract
Background Additive manufacturing has allowed for the creation of a patient-specific custom solution that can resolve many of the limitations previously reported for canine cranioplasty. The purpose of this pilot study was to determine the schedule feasibility and workflow in manufacturing patient-specific titanium implants for canines undergoing cranioplasty immediately following craniectomy. Results Computed tomography scans from patients with tumors of the skull were considered and 3 cases were selected. Images were imported into a DICOM image processing software and tumor margins were determined based on agreement between a board-certified veterinary radiologist and veterinary surgical oncologist. Virtual surgical planning was performed and a bone safety margin was selected. A defect was created to simulate the planned intraoperative defect. Stereolithography format files of the skulls were then imported into a plate design software. In collaboration with a medical solution centre, a custom titanium plate was designed with the input of an applications engineer and veterinary surgery oncologist. Plates were printed in titanium and post-processed at the solution centre. Total planning time was approximately 2 h with a manufacturing time of 2 weeks. Conclusions Based on the findings of this study, with access to an advanced 3D metal printing medical solution centre that can provide advanced software and printing, patient-specific additive manufactured titanium implants can be planned, created, processed, shipped and sterilized for patient use within a 3-week turnaround.

Abstract
Background:Trials and clinical observations have demonstrated the efficacy of mycophenolate mofetil (MMF) for SLE treatment. Long-term use of MMF is associated with adverse events, pregnancy risks, drug monitoring, and increased cost. Current management continues therapy indefinitely. Whether immunosuppression may be safely withdrawn or whether risks of withdrawal outweigh the benefits of continuation is unknown.Objectives:To compare rates of clinically significant disease reactivation (CSDR), major flares, and all flares in patients with quiescent SLE on stable MMF randomized to maintain or withdraw MMF. The goal is to provide guidance for clinicians and patients on the risks of MMF withdrawal.Methods:Adults with quiescent SLE (SELENA-SLEDAI without serologies <4) receiving MMF for ≥2 years for nephritis or ≥ 1 year for non-nephritis were randomized 1:1 to unblinded MMF (maintenance arm, MA) or to a 12-week taper off MMF (withdrawal arm, WA) and followed through 60 weeks. Subjects were on stable hydroxychloroquine; steroids limited to ≤ 10 mg. CSDR, defined as a SLEDAI flare requiring immunosuppression, BILAG flares and adverse events were assessed. Event rates and time to flare were compared using Kaplan-Meier.Results:102 subjects were randomized (50 MA, 52 WA); 1 subject in each arm was ineligible and 10 terminated early (7 MA, 3 WA). Mean disease duration was 13 years; 76% had a history of nephritis; mean baseline SLEDAI was 2.2. 5 MA subjects (10%) had CSDR, compared to 9 WA (17%). Median time to CDSR was 38 weeks in both arms. BILAG A flares occurred in 1MA subject (pancreatitis) vs. 4 WA (cranial neuropathy, panniculitis, 2 nephritis). Kaplan-Meier curves overlapped for CDSR, BILAG A flares, and all SLEDAI flares (Figure). Based on these data, we are 86% confident that the increased risk of CDSR with MMF withdrawal is less than 15% over 60 weeks. AEs were similar between groups; infections occurred more commonly in MA (63 vs. 49).Conclusion:In this cohort of subjects with quiescent SLE on long term MMF serious flares occurred infrequently in subjects continuing or withdrawing MMF without differences in time to flare. MMF withdrawal may be considered in subjects with prolonged quiescent disease.Table 1.Baseline and Demographic CharacteristicsMaintenance armWithdrawal armTotalRandomized5052102Female, n (%)39 (78)47 (90)86 (84)White, n (%)25 (50)19 (37)44 (43)Black, n (%)19 (38)22 (42)41 (40)Hispanic/Latino, n (%)10 (20)12 (23)22 (22)Age, Years, mean (SD)42.4 (12.9)41.6 (12.5)42.0 (12.6)Disease Duration, Years, mean (SD)13.6 (8.2)12.2 (7.9)12.9 (8.0)H/O Lupus Nephritis, n (%)40 (80)38 (73)78 (76.5)On Baseline Steroids, n (%)18 (36)23 (44)41 (40)Prednisone Dose, mg, mean (SD)4.8 (2.7)3.3 (1.7)4.0 (2.3)MMF Duration, Years, mean (SD)6.8 (4.3)6.4 (4.3)6.6 (4.3)Baseline MMF Dose, mg, mean1,6121,6681,640SELENA-SLEDAI*, mean (SD)2.4 (1.76)1.9 (1.76)2.2 (1.77)Positive DsDNA, n (%)35 (70)27 (52)62 (61)Low C31, n (%)14 (28)9 (17)23 (23)Low C41, n (%)6 (12)5 (10)11 (11)Figure.Kaplan-Meier Estimates of Flare EndpointsDisclosure of Interests:Eliza Chakravarty: None declared, Tammy Utset: None declared, Diane L Kamen Consultant of: Consulted on SLE survey development for Lilly and consulted on SLE trial protocol development for EMD Serono in 2019, Gabriel Contreras Grant/research support from: Genentech, Merck, Consultant of: Genentech, Merck, William Joseph McCune: None declared, Kenneth C Kalunian: None declared, Cynthia Aranow: None declared, Megan Clowse Grant/research support from: GSK, Pfizer, Consultant of: UCB, Astra-Zeneca, Speakers bureau: UCB, Ellen Goldmuntz: None declared, Jessica Springer: None declared, Lynette Keyes-Elstein: None declared, Bill Barry: None declared, Ashley Pinckney: None declared, Judith James: None declared

Abstract
SummaryWe have attempted to exploit the Ca2+ -dependent stability of factor VIII in producing factor VIII concentrates of higher yield. Plasma levels of ionised calcium were increased in two ways: (a) whole blood collection into half-strength citrate CPD anticoagulant, leading to free Ca2+ levels of ca 120 µM and (b) apheresis collection of plasma which was then recalcified to free Ca2+ levels
of ca 300 µM under heparin cover. Coagulation factor concentrates were prepared using model versions of our industrial scale manufacturing methods. Factor VIII yield was increased through low citrate collection. This did not compromise factor IX yield or thrombogenic potential. Use of recalcified heparinised plasma did not lead to any improvement in factor VIII yield and resulted in a marked drop in factor IX recovery, possibly from interference by
heparin of factor IX binding in ion-exchange chromatography. The benefits accruable through the use of half-strength citrate CPD anticoagulant support the continued evaluation of this preservative in large scale blood collection and fractionation. The deleterious effects of heparin in charge-mediated plasma fractionations may pose serious difficulties in harvesting vitamin K dependent factors.

Abstract
Diabetic nephropathy remains the principal cause of end-stage renal failure in the UK and its prevalence is set to increase. People with diabetes and end-stage renal failure on maintenance haemodialysis are highly vulnerable, with complex comorbidities, and are at high risk of adverse cardiovascular outcomes, the leading cause of mortality in this population. The management of people with diabetes receiving maintenance haemodialysis is shared between diabetes and renal specialist teams and the primary care team, with input from additional healthcare professionals providing foot care, dietary support and other aspects of multidisciplinary care. In this setting, one specialty may assume that key aspects of care are being provided elsewhere, which can lead to important components of care being overlooked. People with diabetes and end-stage renal failure require improved delivery of care to overcome organizational difficulties and barriers to communication between healthcare teams. No comprehensive guidance on the management of this population has previously been produced. These national guidelines, the first in this area, bring together in one document the disparate needs of people with diabetes on maintenance haemodialysis. The guidelines are based on the best available evidence, or on expert opinion where there is no clear evidence to inform practice. We aim to provide clear advice to clinicians caring for this vulnerable population and to encourage and improve education for clinicians and people with diabetes to promote empowerment and self-management.

Abstract
Glucocorticoids (steroids) are widely used across many medical specialities for their anti-inflammatory and immunosuppressive properties. However, one of their major side effects is the development of hyperglycaemia. It is well recognized that high glucose levels in people with diabetes in hospital are associated with harm and increased lengths of hospital stay. The use of glucocorticoid (steroid) treatment in people with pre-existing diabetes will undoubtedly result in worsening glucose control, and this may be termed 'steroid-induced hyperglycaemia', and will warrant temporary additional, and more active, glycaemic management. A rise in glucose may occur in people without a known diagnosis of diabetes, and this may be termed 'steroid-induced diabetes'. There is a lack of evidence to guide how people with hyperglycaemia should be managed, and much of the guidance given here is a consensus based on best practice collated from around the United Kingdom. Where evidence is available, this is referenced. These guidelines on the management of people with diabetes treated with steroids has been adapted specifically for Diabetic Medicine. The full version of the guidelines can be found on line at: www.diabetes.org.uk/joint-british-diabetes-society or https://abcd.care/joint-british-diabetes-societies-jbds-inpatient-care-group.

Abstract
Aintree LOSS is a community-based, multidisciplinary weight management programme for patients with severe and complex obesity, focusing on a flexible and individualized service with follow-up for up to 2 years. We evaluated all 2472 patients referred to the service between October 2009 and 2013. Demographic data were recorded at baseline, with the Index of Multiple Deprivation (IMD) used to measure socioeconomic deprivation. Weight was recorded at each visit. Mean body mass index at baseline was 45.6 (standard deviation 6.8), and 58.9% of patients lived in areas in the most deprived decile nationally. Of 2315 appropriate referrals, 1249 (55.1%) attended >2 visits; mean final weight loss was 3.50 ± 8.55 kg, and 24.1% achieved ≥5% weight loss. Of the patients, 754 (33.3%) attended for over 6 months; mean final weight loss was 4.94 ± 10 kg, and 34% achieved 5% weight loss. Multivariate logistic regression analysis showed increasing age, residence in a less deprived area and sleep apnoea to be independently associated with attendance for >6 months, and there was a linear relationship between 6-month attendance and deprivation quintile. Year-on-year analyses showed improvement in engagement over time, coinciding with efforts to improve access to the service. This work shows a multidisciplinary, community-based weight loss programme prioritizing a fully flexible and individualized approach functioning effectively in real-world practice. Maintaining engagement remains a challenge in weight loss programmes, and our results suggest younger patients living in areas with greater deprivation should be a target for efforts to improve engagement.

The mushroom body D1 dopamine receptor controls innate courtship drive. GENES BRAIN AND BEHAVIOR 2017; 17:158-167.

Abstract
Mating is critical for species survival and is profoundly regulated by neuromodulators and neurohormones to accommodate internal states and external factors. To identify the underlying neuromodulatory mechanisms, we investigated the roles of dopamine receptors in various aspects of courtship behavior in Drosophila. Here, we report that the D1 dopamine receptor dDA1 regulates courtship drive in naïve males. The wild‐type naïve males actively courted females regardless their appearance or mating status. On the contrary, the dDA1 mutant (dumb) males exhibited substantially reduced courtship toward less appealing females including decapitated, leg‐less and mated females. The dumb male's reduced courtship activity was due to delay in courtship initiation and prolonged intervals between courtship bouts. The dampened courtship drive of dumb males was rescued by reinstated dDA1 expression in the mushroom body α/β and γ neurons but not α/β or γ neurons alone, which is distinct from the previously characterized dDA1 functions in experience‐dependent courtship or other learning and memory processes. We also found that the dopamine receptors dDA1, DAMB and dD2R are dispensable for associative memory formation and short‐term memory of conditioned courtship, thus courtship motivation and associative courtship learning and memory are regulated by distinct neuromodulatory mechanisms. Taken together, our study narrows the gap in the knowledge of the mechanism that dopamine regulates male courtship behavior.

Abstract
An outbreak of neurological disease was investigated in red-legged partridges between 8 and 28 days of age. Clinical signs included torticollis, head tilt and incoordination and over an initial eight day period approximately 30-40 fatalities occurred per day. No significant gross post mortem findings were detected. Histopathological examination of the brain and bacterial cultures followed by partial sequencing confirmed a diagnosis of encephalitis due to Listeria monocytogenes. Further isolates were obtained from follow-up carcasses, environmental samples and pooled tissue samples of newly imported day-old chicks prior to placement on farm. These isolates had the same antibiotic resistance pattern as the isolate of the initial post mortem submission and belonged to the same fluorescent amplified fragment length polymorphism (fAFLP) subtype. This suggested that the isolates were very closely related or identical and that the pathogen had entered the farm with the imported day-old chicks, resulting in disease manifestation in partridges between 8 and 28 days of age. Reports of outbreaks of encephalitic listeriosis in avian species are rare and this is to the best of our knowledge the first reported outbreak in red-legged partridges.
