Abstract
Abstract
Study question
Is there an association between serum oestradiol, vaginal microbial composition and pregnancy outcome in the early first trimester?
Summary answer
In women with a vaginal microbiome deplete of Lactobacillus species at the time of Pregnancy of Uncertain Viability (IPUV), higher serum oestradiol associates with livebirth.
What is known already
During pregnancy, oestradiol mediates vaginal mucosal properties and increases glycogen deposition in epithelial cells which is thought to support colonisation of Lactobacillus species. Low levels of Lactobacillus associates with adverse outcomes such as miscarriage and preterm birth. The direct relationship between systemic oestradiol and the vaginal microbiome has never been studied in pregnancy. However studies have shown a positive correlation between serum oestrone, vaginal glycogen and Lactobacillus abundance in menopausal women.
Study design, size, duration
This was a prospective cohort study where one-hundred women were recruited in early pregnancy at the time of IPUV and donated paired blood and vaginal samples. 40 women had an eventual miscarriage, 58 had a livebirth and two pregnancies were terminated. All 100 women donated one paired serum and vaginal sample at this time point, and 22 women with Lactobacillus depletion at the time of IPUV donated further longitudinal vaginal samples.
Participants/materials, setting, methods
Participants were recruited from an Early Pregnancy Unit and underwent transvaginal ultrasound assessment of their pregnancy. Serum samples were analysed with an immunoassay on a ROCHE COBAS E411 analyser for Oestradiol (pg/ml) and Progesterone (ng/ml). Bacterial DNA was extracted from paired vaginal swabs and sequenced using Illumina MiSeq sequencing of 16S rRNA gene amplicons.
Main results and the role of chance
Lactobacillus dominance of the vagina was associated with higher serum levels of E2 and progesterone compared to depletion (E2=398pg/ml vs 302pg/ml(p = 0.02), P4=23.1ng/ml vs 17ng/ml(p = 0.02)). E2 and P4 were positively correlated (r = 0.6, p < 0.05). At species level, L. crispatus dominance associated with significantly higher levels of E2 compared to high-diversity communities (468pg/ml vs 302pg/ml(p = 0.03) but no such relationship was observed for P4. Both E2 and P4 levels were lower in women who eventually miscarried. However there was no significant difference in the vaginal bacterial composition at genera or species level at this early gestational age (P = 0.08) regardless of per vaginal bleeding. However in women with Lactobacillus depleted microbiota, livebirth was associated with significantly higher E2 levels compared to women suffering miscarriage (212pg/ml in miscarriage vs 395pg/ml in livebirth, p = 0.003) (OR = 22.4 P = 0.004). In 22 women who had Lactobacillus depletion at the time of IPUV (7 with an eventual outcome of miscarriage, and 15 with an eventual outcome of livebirth), longitudinal vaginal bacterial DNA sequencing was performed. In 7/15 women with livebirth, and higher E2 levels, the microbial composition changed to become more Lactobacillus dominant during pregnancy, whereas in those with miscarriage, only 1/7 changed to become Lactobacillus dominant.
Limitations, reasons for caution
In this study, serum oestradiol levels were compared to the local vaginal bacterial environment. The ideal would be to study local vaginal oestradiol, glycogen and the bacterial composition.
Wider implications of the findings: In contrast to previous studies in menopause where low oestrogen levels associate with the vaginal microbial composition, this study uses the high oestradiol environment of early pregnancy to study the mechanistic relationship between oestradiol and vaginal Lactobacillus abundance.

Abstract
Abstract
Study question
To investigate the vaginal microbial composition and the local immune response in chromosomally normal and abnormal miscarriages and compare this to uncomplicated pregnancies delivering at term.
Summary answer
We show that euploid miscarriage is associated with a significantly higher prevalence of Lactobacillus spp. deplete vaginal microbial communities compared to aneuploid miscarriage.
What is known already
Emerging evidence supports the role of the vaginal microbiota in adverse pregnancy outcome, but the underlying mechanisms are poorly understood. A dominance of Lactobacillus spp. in pregnancy provides protection against pathogenic bacteria by producing lactic acid and antimicrobial compounds. A depletion in Lactobacillus spp. is often linked to adverse pregnancy outcomes.Current work also implicates the reproductive tract microbiota as a key modulator of local inflammatory and immune pathways. We have previously shown that miscarriage is associated with vaginal dysbiosis but without knowledge of the cytogenetic status of those miscarriages or the local immune profile.
Study design, size, duration
This study was a prospective observational cohort study based at Queen Charlotte’s & Chelsea Hospital, Early Pregnancy Unit, London between March 2014-February 2019. Vaginal swabs were collected from the posterior vaginal fornix of 167 patients.
Participants/materials, setting, methods
We used 16S rRNA gene based metataxonomics to interrogate the vaginal microbiota in a cohort of 167 women, 93 miscarriage patients (54 euploid and 39 aneuploid using molecular cytogenetics) and 74 women who delivered at term and correlate this with the aneuploidy status of the miscarriages. We also measured the concentrations of IL-2, IL-4, IL-6, IL-8, TNF-α, IFN-γ, IL-1β, IL-18 and IL-10 in cervical vaginal fluid using Human Magnetic Luminex Screening Assay (8-plex).
Main results and the role of chance
We show that euploid miscarriage is associated with a significantly higher prevalence of Lactobacillus spp. deplete vaginal microbial communities compared to aneuploid miscarriage (P=0.008). In women having Lactobacillus spp. deplete vaginal microbial communities, euploid miscarriage associates with higher concentrations of pro-inflammatory cytokines IL-1β, IL-8, IL-6 (P<0.001, P=0.01 and P<0.001 respectively) and lower concentrations of anti-inflammatory cytokines IL10 (P<0.001) when compared to viable term pregnancy. We identified Prevotella bivia and Streptococcus as particularly common in euploid miscarriage and as drivers of pro-inflammatory cytokines (IL-1β, IL-6 and TNF-α). Co-occurrence network analyses revealed low levels of co-occurrence between Lactobacillus crispatus and other organisms and strong co-occurrence between Streptococcal species. Our data show a combination of both an adverse vaginal microbiota and a cytokine response to it influences early pregnancy outcome. Although this may be a reflection of intrinsic maternal immune response, it appears that the cytokine response is largely driven by the bacterial taxa present in the vagina, which presents an opportunity for specific, directed intervention. The negative co-occurrence between L.crispatus and all other organisms suggests a possible therapeutic role for probiotics containing this organism. The influence of Streptococci also suggests a potential benefit of targeted antibiotics with probiotics for some patients.
Limitations, reasons for caution
There were no longitudinal samples in this cohort and our results are based on the assumption that the vaginal microbial composition is stable throughout the first trimester.Future longitudinal studies with larger sample sizes are needed to corroborate these findings and provide insights to the mechanisms that trigger the inflammatory response.
Wider implications of the findings
These findings support the hypothesis that the vaginal microbiota plays an important aetiological role in euploid miscarriage and may represent a target to modify the risk of pregnancy loss.

Background
Remote patient monitoring (RPM) is an underutilised telehealth intervention that can enhance self-management of cardiovascular and pulmonary disease and reduce acute care use. However, studies of effectiveness of RPM interventions vary widely. This study aimed to explain the variation in outcomes related to RPM interventions within cardiac and pulmonary populations. Specifically, we aimed to answer why some RPM interventions are more successful than others in reducing demand on acute care services.
Methods
In brief, search terms for remote monitoring and acute care utilisation were used across three electronic databases: PubMed, EMBASE and CINAHL. The search, conducted in October 2020, included articles published in the last five years (2015-2020). Articles were included if they used RPM to monitor an individual’s biometrics (e.g. heart rate, blood pressure) from a distance while they are not in hospital. Realist review methodology was used to enable exploration of how, why and for whom interventions do and do not work. Outcomes were evaluated to determine contextual factors and potential mechanisms that led to variation in cardiac and pulmonary intervention outcomes.
Results
After screening, 91 articles met the eligibility criteria and were included. We found that across a broad range of RPM interventions 31 factors emerged that are likely to impact the effectiveness of cardiac and pulmonary RPM innovations. These were synthesised into six theories of intervention success: 1) targeting populations at high risk; 2) accurately detecting a decline in health; 3) providing responsive and timely care; 4) personalising care; 5) enhancing self-management and, 6) ensuring collaborative and coordinated care.
Conclusion
While RPM interventions are complex, if they are designed with patients, providers and the implementation setting in mind and with the key variables identified within this review incorporated, it is more likely that they will be effective at reducing acute hospital events.

Mental health and wellbeing coordinators in primary schools to support student mental health: protocol for a quasi-experimental cluster study. BMC Public Health 2021; 21:1467.

Abstract
Background Half of mental health disorders begin before the age of 14, highlighting the importance of prevention and early-intervention in childhood. Schools have been identified globally by policymakers as a platform to support good child mental health; however, the majority of the research is focused on secondary schools, with primary schools receiving very little attention by comparison. The limited available evidence on mental health initiatives in primary schools is hindered by a lack of rigorous evaluation. This quasi-experimental cluster study aims to examine the implementation and effectiveness of a Mental Health and Wellbeing Co-ordinator role designed to build mental health capacity within primary schools. Methods This is a primary (ages 5–12) school-based cluster quasi-experimental study in Victoria, Australia. Before baseline data collection, 16 schools selected by the state education department will be allocated to intervention, and another 16 matched schools will continue as ‘Business as Usual’. In intervention schools, a mental health and well-being coordinator will be recruited and trained, and three additional school staff will also be selected to receive components of the mental health training. Surveys will be completed by consenting staff (at 2-, 5-, 10- and 17-months post allocation) and by consenting parents/carers (at 3-, 10- and 17-months post allocation) in both intervention and business as usual schools. The primary objective is to assess the change in teacher’s confidence to support student mental health and wellbeing using the School Mental Health Self-Efficacy Teacher Survey. Secondary objectives are to assess the indirect impact on systemic factors (level of support, prioritisation of child mental health), parent and teachers’ mental health literacy (stigma, knowledge), care access (school engagement with community-based services), and student mental health outcomes. Implementation outcomes (feasibility, acceptability, and fidelity) and costs will also be evaluated. Discussion The current study will examine the implementation and effectiveness of having a trained Mental Health and Wellbeing Coordinator within primary schools. If the intervention increases teachers’ confidence to support student mental health and wellbeing and builds the capacity of primary schools it will improve student mental health provision and inform large-scale mental health service reform. Trial registration The trial was retrospectively registered in the Australian New Zealand Clinical Trials Registry (ANZCTR) on July 6, 2021. The registration number is ACTRN12621000873820.

Use of antibiotic coated intramedullary nails in open tibia fractures: A European medical resource use and cost-effectiveness analysis. Injury 2021; 52:1951-1958. [PMID: 34001375 DOI: 10.1016/j.injury.2021.04.053] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Revised: 03/01/2021] [Accepted: 04/12/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE In patients with open tibial fractures, bone and wound infections are associated with an increased hospital length of stay and higher costs. The infection risk increases with the use of implants. Innovations to reduce this risk include antibiotic-coated implants. This study models whether the use of a gentamicin-coated intramedullary tibial nail is cost-effective for trauma centers managing patients with a high risk of infection. EFFICACY Absolute infection risk and relative risk reduction, by fracture grade, for antibiotic-coated nails compared to standard nails for patients with open tibial fractures were estimated based on the results of a meta-analysis, which assessed the additional benefit of locally-administered prophylactic antibiotics in open tibia fractures treated with implants. The observed efficacy of antibiotic-coated nails in reducing infections was applied in an economic model. METHODS The model compared infection rates, inpatient days, theatre usage and costs in high risk patients, with a Gustilo-Anderson (GA) grade III open fracture, for two patient cohorts from a trauma center perspective, with a 1-year time horizon. In one cohort all GAIII patients received a gentamicin-coated nail whilst GAI and GAII patients received a standard nail. All patients in the comparator cohort received a standard nail. Four European trauma centers provided patient-level data (n=193) on inpatient days, procedures and related costs for patients with and without infections. RESULTS Using the gentamicin-coated nail in patients at high risk of infection (GAIII) was associated with 75% lower rate of infection and cost savings (€477 - €3.263) for all included centers; the higher cost of the implant was offset by savings from fewer infections, inpatient days (-26%) and re-operations (-10%). This result was confirmed by extensive sensitivity analyses. CONCLUSIONS Analyses demonstrated that infection rates and total costs for in-hospital treatment could be potentially reduced by 75% and up to 15% respectively, by using a gentamicin-coated nail in patients at high risk of infection. Fewer infections, reduced inpatient days and re-operations may be potentially associated with use of antibiotic-coated implants. Results are sensitive to the underlying infection risk, with greatest efficacy and cost-savings when the coated implant is used in high risk patients.

Abstract
Background Negative workplace experiences (NWPEs), such as gender discrimination, bullying, sexual harassment and ethnic discrimination, are concerns in today’s surgical society. These negative experiences potentially impair surgeons’ performance and might impact patient care or outcomes negatively. This study aimed to assess the experience of NWPEs across the European surgical workforce. Methods A prospective online 34-point questionnaire was designed using a combination of Likert scale, multiple-choice and short-answer questions. Invitations were distributed through surgical associations via email/social media between 1 September and 15 November 2019. Data were analysed using non-parametric methods. Results Some 840 complete responses were included in the analysis. The distribution across genders and stage of surgical training was even. Of the respondents, 20 per cent (168 respondents) considered quitting their job, 4.5 per cent (38) took time off and 0.5% (4) left surgery due to NWPEs; 12.9 per cent of females and 4.4 per cent of males experienced some form of physical harassment. Females and those in training were significantly more likely to experience or witness gender discrimination and sexual harassment. Just over half of the respondents (448) did not report negative experiences, with most of these (375 respondents) being unaware of whom to report to. Nearly a fifth of respondents felt that NWPEs influenced patient care or outcomes negatively. Conclusion NWPEs were frequent, especially among females and those in training. While a substantial proportion of respondents experienced physical harassment, many individuals were unaware of how to raise concerns. Adverse effects on patient outcomes, surgical training and workforce retention indicate a need for urgent action.

Abstract
PURPOSE Biosynthetic absorbable meshes have emerged as suitable alternatives to permanent synthetic and biologic meshes in complex ventral hernia repair in contaminated wounds. Evidence regarding the use of these products in clean wounds is currently scant. This paper presents a large single surgeon series using GORE®BIO-A® (W.L. Gore & Associates, Newark, DE) (Bio-A) tissue reinforcement in high risk patients with predominantly CDC Class I wounds. METHODS Retrospective review of a prospectively maintained database of consecutive patients who underwent open ventral hernia repair with biosynthetic absorbable mesh was conducted. Ventral Hernia Working Group (VHWG) classification based on patient demographics and Centers for Disease Control (CDC) wound type were collected prospectively. All patients were followed up for a minimum of 12 months post-operatively. RESULTS 155 patients were included with a mean post-operative follow up of 29 months (range 12-62 months). Mean age was 61.8 years with an average BMI of 33.5 kg/m2. 147 patients (94.9%) were classified as VHWG 2 or 3 based on comorbidities or surgical field contamination. 69% (n = 107) of wounds were designated CDC Class I. Mean hernia size was 119.7cm2 with recurrent defects comprising 32.3% (n = 50). Retrorectus mesh repair was achieved in 84.5% of patients (n = 131). Post-operative wound events occurred in 19.3%. No mesh was explanted. Hernia recurrence rate was 9.0% with a mean time to recurrence of 14 months. There was no significant difference in recurrence rates between clean and contaminated wounds. CONCLUSION This study supports the use of Bio-A in high risk ventral hernias, demonstrating a safe and durable repair across all wound classes. Ongoing follow-up continues to monitor for late complications and recurrence.

Abstract
BACKGROUND The diagnosis of spindle cell neoplasms (SCN) of the upper gastrointestinal (GI) tract, hepatobiliary tract, and pancreas detected by fine needle aspiration (FNA) is challenging. We describe a single-center experience of these samples with follow-up data and characterization of the morphologic findings. METHODS We retrospectively reviewed pathology records for all FNAs diagnostic for or suggestive of SCN on esophagus, stomach, small bowel, liver, and pancreas in a 15 year period. All cases with at least 6 month follow-up were included. Surgical material (biopsy or resection) was the diagnostic gold standard. All FNAs with subsequent surgical specimens were reviewed and assessed for cellularity, architectural features, and nuclear features. RESULTS In 15 years, 5101 FNAs of the upper GI tract, hepatobiliary tract, and pancreas were performed. SCN was diagnosed in 98 (2%) patients. Seventy-two patients had definitive pathologic diagnoses: 68 were neoplastic and four were non-neoplastic. Cytomorphologic review in relationship to final diagnosis revealed three statistically significant features: low cellularity favors a benign process (P = .00544), epithelioid nuclear morphology favors malignancy (P = .00278), and identification of perinuclear vacuoles favors a diagnosis of GIST over non-GIST SCN (P = .04236). CONCLUSIONS Among cases with follow-up, final pathologic diagnoses were SCN in 94% of cases diagnosed as SCN on FNA of upper GI, hepatobiliary tract, and pancreas. Although some cytomorphologic criteria are more suggestive of malignancy, arriving at a specific diagnosis relies on collaboration of clinical, radiologic, cytomorphologic, and immunohistochemical data.

[PMID: 33910631 PMCID: PMC8082773 DOI: 10.1186/s13643-021-01682-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Accepted: 04/20/2021] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND There is growing interest in the use of routine patient-reported outcome measures (PROMs) to influence the care of individual patients with stroke. However, there are significant gaps in our understanding as to how PROMs influence post-stroke patient care and clinical practice. This is due to factors including the number of purported uses for PROMs and that PROMs are complex interventions, which attempt to stimulate varied actions or behaviours. Therefore, the objective of this realist synthesis is to offer theory-based explanations as to how PROMs influence post-stroke clinical practice and patient care. METHODS This is a protocol for a realist synthesis, which involves three distinct phases: theory building (phase 1), theory testing and refinement (phase 2) and synthesis (phase 3). Phase 1 will develop initial rough programme theories (IRPTs), through literature searches (from January 2000 onwards) of MEDLINE, EMBASE, PsycINFO, CINAHL, Cochrane Library and the grey literature. Only secondary sources will be included that contribute to the development of IRPTs. Only two IRPTs, prioritised by the stakeholder group, will be taken forward to be tested and refined during phase 2. Further novel searches will be employed in phase 2, utilising the same criteria as phase 1; however, phase 2 searches will not utilise grey literature searches, and only primary research studies that contribute to the refinement of programme theories under investigation will be included. Two independent reviewers will screen and select all returned results. The reviewers will code and annotate relevant sources, resulting in 'fragments' to be extracted and graded based on the richness of their contribution to explanation and causal insight. Further, these fragments will be organised into 'Context-Mechanism-Outcome' configurations. Phase 3 of the review will involve the synthesis of context-mechanism-outcome configurations to form middle-range theory-based explanations and developed logic models for stakeholders to understand how PROMs in post-stroke clinical practice and patient care work for whom, how and under what circumstances. DISCUSSION The resulting realist synthesis will provide guidance on the implementation of PROMs within routine post-stroke clinical practice and patient care and act as a touchstone for further testing and refinement of PROMs programmes.

Abstract
Abstract
Introduction
Paraplegia post-thoracoabdominal aortic aneurysm (TAAA) repair remains both a devastating and poorly understood complication. We related temporal changes in cellular and protein composition of cerebrospinal fluid (CSF) to neurological outcomes after TAAA repair to gain mechanistic insights driving paraplegia.
Method
Patients undergoing TAAA repair (open or endovascular) with a CSF drain were prospectively recruited between 2016-2018. CSF was collected pre-operatively and 24-hourly until removal. Daily neurological examinations were performed by blinded neurologists to the study. CSF cell content was characterised by flow cytometry and proteome analysed by tandem-mass-tag proteomics. An in-vivo rat model was modified using 15 minutes of aortic occlusion to produce consistent paraplegia. Rats were analysed neuro-behaviourally and histologically.
Result
CSF was analysed from 52 patients (age: 70.27+/-11.4; 66% male; open (n=9), endovascular (n=43)). 12 developed paraplegia of whom 5 remained permanently-paraplegic. Demographics were comparable between paraplegics, those who recovered and without post-op neurology. Permanent paraplegia was associated with a significant infiltration of CSF CD45+ leucocytes (P<0.0001). Levels of ADVS-1 was >3-fold higher in permanent-paraplegics CSF versus those who recovered (P=0.0008). ADVS-1 >15ng/ml predicted permanent paraplegia with 100% specificity. Pre-treatment with ADVS-1 inhibition significantly improved walking (<0.001) and increased astrocytic staining in the lateral corticospinal, reticulospinal and rubrospinal tracts versus controls (P=0.03, 0.04, 0.04 respectively).
Conclusion
Permanent paraplegia is associated with shedding of ADVS-1 from parenchymal cord into CSF and blood/spinal-cord barrier disruption leading to cord oedema/leucocyte infiltration. Pre-treatment with ADVS-1 inhibition led to neurobehavioural and histological improvements offering translational hope for this devastating complication.
Take-home message
ADVS-1 is a novel biomarker of paraplegia where accurate biomarkers have proven challenging but more importantly it has proven a therapeutic target with genuine translational potential.

Abstract
The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision detectors, and by the massive far detector system located deep underground. This configuration sets up DUNE as a machine for discovery, as it enables opportunities not only to perform precision neutrino measurements that may uncover deviations from the present three-flavor mixing paradigm, but also to discover new particles and unveil new interactions and symmetries beyond those predicted in the Standard Model (SM). Of the many potential beyond the Standard Model (BSM) topics DUNE will probe, this paper presents a selection of studies quantifying DUNE's sensitivities to sterile neutrino mixing, heavy neutral leptons, non-standard interactions, CPT symmetry violation, Lorentz invariance violation, neutrino trident production, dark matter from both beam induced and cosmogenic sources, baryon number violation, and other new physics topics that complement those at high-energy colliders and significantly extend the present reach.

Abstract
We present the first results of the Fermilab National Accelerator Laboratory (FNAL) Muon g-2 Experiment for the positive muon magnetic anomaly a_{μ}≡(g_{μ}-2)/2. The anomaly is determined from the precision measurements of two angular frequencies. Intensity variation of high-energy positrons from muon decays directly encodes the difference frequency ω_{a} between the spin-precession and cyclotron frequencies for polarized muons in a magnetic storage ring. The storage ring magnetic field is measured using nuclear magnetic resonance probes calibrated in terms of the equivalent proton spin precession frequency ω[over ˜]_{p}^{'} in a spherical water sample at 34.7 °C. The ratio ω_{a}/ω[over ˜]_{p}^{'}, together with known fundamental constants, determines a_{μ}(FNAL)=116 592 040(54)×10^{-11} (0.46 ppm). The result is 3.3 standard deviations greater than the standard model prediction and is in excellent agreement with the previous Brookhaven National Laboratory (BNL) E821 measurement. After combination with previous measurements of both μ^{+} and μ^{-}, the new experimental average of a_{μ}(Exp)=116 592 061(41)×10^{-11} (0.35 ppm) increases the tension between experiment and theory to 4.2 standard deviations.

Abstract
Splenogonadal fusion is a rare benign congenital anomaly in which there is an abnormal connection between the gonad and the spleen. It was first described over 100 years ago with limited reports in the literature since then. Its similarity in presentation to testicular neoplasia poses a significant challenge in diagnosis and management, often resulting in radical orchidectomy. We present the case of a 31-year-old man who presented with a rapidly growing left-sided testicular mass and suspicious ultrasound findings; histology from the subsequent radical inguinal orchidectomy showed findings consistent with splenogonadal fusion. We describe points for consideration in the clinical history, examination and imaging that could suggest splenogonadal fusion, including preoperative technetium-99m-sulfur colloid imaging and intraoperative frozen section evaluation, which may confirm the diagnosis and prevent unnecessary orchidectomy.

Abstract
OBJECTIVE To compare early hip osteoarthritis (OA) features on magnetic resonance imaging (MRI) in high-impact athletes with and without hip and/or groin pain, and to evaluate associations between early hip OA features, the International Hip Outcome Tool (iHOT33) and Copenhagen Hip and Groin Outcome Score (HAGOS). DESIGN This case-control study evaluated data of the femoroacetabular impingement and hip osteoarthritis cohort (FORCe). One hundred and eighty-two symptomatic (hip and/or groin pain >6 months and positive flexion-adduction-internal-rotation (FADIR) test) and 55 pain-free high-impact athletes (soccer or Australian football (AF)) without definite radiographic hip OA underwent hip MRI. The Scoring Hip Osteoarthritis with MRI (SHOMRI) method quantified and graded the severity of OA features. Each participant completed the iHOT33 and HAGOS. RESULTS Hip and/or groin pain was associated with higher total SHOMRI (0-96) (mean difference 1.4, 95% CI: 0.7-2.2), labral score (adjusted incidence rate ratio (aIRR) 1.33, 95% CI: 1.1-1.6). Differences in prevalence of cartilage defects, labral tears and paralabral cysts between symptomatic and pain-free participants were inconclusive. There was a lower prevalence of effusion-synovitis in symptomatic participants when compared to pain-free participants (adjusted odds ratio (aOR) 0.46 (95% CI: 0.3-0.8). Early hip OA features were not associated with iHOT33 or HAGOS. CONCLUSIONS A complex and poorly understood relationship exists between hip and/or groin pain and early hip OA features present on MRI in high-impact athletes without radiographic OA. Hip and/or groin pain was associated with higher SHOMRI and labral scores.

Abstract
BACKGROUND People with intellectual disability (ID) are often socially isolated, and many experience stigma and discrimination. Increased contact with the general public is thought to overcome prejudices. This large-scale international study had three main aims: to determine the type and frequency of contact that the general public has with people with ID; to identify the personal characteristics of those who have greater contact; and to examine the public's level of comfort at the prospect of having contact with people with ID. METHOD Self-completed online questionnaires were administered to nationally representative panels of respondents in 17 countries; totally 24 504 persons. Multivariate analyses were used to identify respondents more likely to have had frequent personal contact with persons with ID from those with infrequent or no contact and those respondents who were most comfortable at meeting a person with ID. RESULTS Internationally around one in four of the general population reports having frequent personal contact with people who have an ID although this varied from 7% in Japan to 46% in Panama. The principal forms of contact were through friendships, neighbours or extended family members. Over all countries, volunteering and engagement with Special Olympics were the two main predictors of frequent personal contact followed by employment in the education, health or social care field, being a parent of children under 18 years, playing sports and being employed. People who reported frequent personal contact were also more comfortable at meeting a person with ID. CONCLUSIONS This international dataset provides a baseline against which public contact can be compared across countries and changes monitored over time. The findings suggest ways in which greater contact can be promoted and making the public more comfortable at meeting people with ID.

Abstract
Background and objective Low-dose long-term azithromycin is recommended in clinical practice guidelines for obstructive airway diseases (OADs), however, an optimal therapeutic regimen is not yet established. This study aimed to understand the patterns of azithromycin use in OADs, characterise the patients who received it, and evaluate its safety and efficacy using real-world data. METHODS We audited 91 patients who had received azithromycin for at least 4 weeks for the management of asthma, chronic obstructive pulmonary disease (COPD) or non-cystic fibrosis bronchiectasis. RESULTS The mean age was 65±18 years, 60% were female, and 48% were ex-smokers. The majority had asthma (75%) either alone (50%) or in combination with COPD (12%) or bronchiectasis (13%). Most (64%) reported cough or sputum at baseline. The most common treatment regimen was azithromycin 250mg daily (73%) for more than 1 year (57%), with only seven adverse events. There was a significant reduction in the proportions of patients requiring emergency department visits (48% versus 32%; p<0.001) and hospital admissions (35% versus 31%; p<0.001) after starting azithromycin. In 88% of cases, physicians favoured the use of azithromycin. CONCLUSION Physicians are currently using low-dose azithromycin for a long duration of more than one year for the management of OADs. The typical case-definition is an older non-smoking adult with persistent asthma, often in combination with another OAD, and presenting with bothersome cough or sputum. Azithromycin was well tolerated and led to reduced healthcare utilisation. Further research is required to establish an optimal dosage regimen of azithromycin in OADs.

Abstract
The alarming reduction in drug effectiveness against bacterial infections has created an urgent need for the development of new antibacterial agents that circumvent bacterial resistance mechanisms. We report here a series of DNA gyrase and topoisomerase IV inhibitors that demonstrate potent activity against a range of Gram-positive and selected Gram-negative organisms, including clinically-relevant and drug-resistant strains. In part 1, we present a detailed structure activity relationship (SAR) analysis that led to the discovery of our previously disclosed compound, REDX05931, which has a minimum inhibitory concentration (MIC) of 0.06 μg mL-1 against fluoroquinolone-resistant Staphylococcus aureus. Although in vitro hERG and CYP inhibition precluded further development, it validates a rational design approach to address this urgent unmet medical need and provides a scaffold for further optimisation, which is presented in part 2.

Abstract
We report on the first measurement of flux-integrated single differential cross sections for charged-current (CC) muon neutrino (ν_{μ}) scattering on argon with a muon and a proton in the final state, ^{40}Ar (ν_{μ},μp)X. The measurement was carried out using the Booster Neutrino Beam at Fermi National Accelerator Laboratory and the MicroBooNE liquid argon time projection chamber detector with an exposure of 4.59×10^{19} protons on target. Events are selected to enhance the contribution of CC quasielastic (CCQE) interactions. The data are reported in terms of a total cross section as well as single differential cross sections in final state muon and proton kinematics. We measure the integrated per-nucleus CCQE-like cross section (i.e., for interactions leading to a muon, one proton, and no pions above detection threshold) of (4.93±0.76_{stat}±1.29_{sys})×10^{-38} cm^{2}, in good agreement with theoretical calculations. The single differential cross sections are also in overall good agreement with theoretical predictions, except at very forward muon scattering angles that correspond to low-momentum-transfer events.

Abstract
OBJECTIVE To evaluate whether a particular group of women with intrahepatic cholestasis of pregnancy (ICP), based on their presenting characteristics, would benefit from treatment with ursodeoxycholic acid (UDCA). DESIGN Secondary analysis of the PITCHES trial (ISRCTN91918806). SETTING United Kingdom. POPULATION OR SAMPLE 527 women with ICP. METHODS Subgroup analyses were performed to determine whether baseline bile acid concentrations or baseline itch scores moderated a woman's response to treatment with UDCA. MAIN OUTCOME MEASURES Bile acid concentration and itch score. RESULTS In women with baseline bile acid concentrations less than 40 μmol/l, treatment with UDCA resulted in increased post-randomisation bile acid concentrations (geometric mean ratio 1.19, 95% CI 1.00-1.41, P = 0.048). A test of interaction showed no significance (P = 0.647). A small, clinically insignificant difference was seen in itch response in women with a high baseline itch score (-6.0 mm, 95% CI -11.80 to -0.21, P = 0.042), with a test of interaction not showing significance (P = 0.640). Further subgroup analyses showed no significance. Across all women there was a weak relationship between bile acid concentrations and itch severity. CONCLUSIONS There was no subgroup of women with ICP in whom a beneficial effect of treatment with UDCA on bile acid concentration or itch score could be identified. This confirms that its routine use in women with this condition for improvement of bile acid concentration or itch score should be reconsidered. TWEETABLE ABSTRACT PITCHES: No group of women with ICP has been found in whom UDCA reduces bile acid concentrations or pruritus.

Abstract
Opportunity exists to decrease healthcare-related exposure to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), preserve infection control resources, and increase care capacity by reducing the time to diagnosis of coronavirus disease 2019 (COVID-19). A retrospective cohort analysis was undertaken to measure the effect of targeted rapid molecular testing for SARS-CoV-2 on these outcomes. In comparison with standard platform testing, rapid testing was associated with a 65.6% reduction (12.6 h) in the median time to removal from the isolation cohort for patients with negative diagnostic results. This translated to an increase in COVID-19 treatment capacity of 3028 bed-hours and 7500 fewer patient interactions that required the use of personal protective equipment per week.

Abstract
Abstract
Background
All sustainable developmental goals (SDGs) require implementing sustainable strategies and monitoring to track progress. But what is known of sub-Sahara Africa (SSA)'s efforts in following this stride to reduce by 30% mortality from non-communicable diseases (NCDs) through prevention (SDG 3.4), by considering the effect of social determinants of health (SODHs) on type 2 diabetes increasing prevalence?
Methods
Our search produced 2005 unique articles. Only 10 studies were used in the analysis of this study. These studies include 1 from Botswana, 2 from Ghana, 2 from Kenya, 3 from Nigeria and 2 from South Africa. The findings were evaluated in a greater extent.
Results
All studies (100%) showed non-adherence to exercise and poor glycemic control. 7 studies (70%) on education revealed lack of knowledge or misconceptions, 5 studies (50%) with obesity showed a strong linkage between obesity and type 2 diabetes, and 4 studies (40%) on diet, showed diets high in carbohydrates, saturated fats, and sodium predisposition to type 2 diabetes. All studies (100%) linked urbanization with an increased prevalence of type 2 diabetes.
Conclusions
Changes in SODHs seem to be contributing to the growing prevalence of diabetes in SSA. These changes with other key data should be considered and tailored to policy processes, environment, infrastructures, and norms for prevention strategies and informing dashboard development for SDG 3.4.
Key messages
Social determinants of health must reflect in relevant causal pathways, settings, and sectors for preventive intervention such as in taxation; regulation of food advertising, school, and healthcare. Analysis of the effect of the changing social determinants of health on type 2 diabetes, will assist in establishing indicators for the dashboard development for SDG 3.4 for sub-Sahara Africa.

Abstract
INTRODUCTION Although there is evidence to suggest a high rate of cerebrovascular complications in patients with SARS-CoV-2 infection, anecdotal reports indicate a falling rate of new ischemic stroke diagnoses. We conducted an exploratory single-center analysis to estimate the change in number of new stroke diagnoses in our region, and evaluate the proximate reasons for this change during the COVID-19 pandemic at a tertiary care center in New Jersey. PATIENTS AND METHODS A Comprehensive Stroke Center prospective cohort was retrospectively analyzed for the number of stroke admissions, demographic features, and short-term outcomes 5 months prior to 3/1/2020 (pre-COVID-19), and in the 6 weeks that followed (COVID-19 period). The primary outcome was the number of new acute stroke diagnoses before and during the COVID-19 period, as well as the potential reasons for a decline in the number of new diagnoses. RESULTS Of the 328 included patients, 53 (16%) presented in the COVID-19 period. There was a mean fall of 38% in new stroke diagnoses (mean 1.13/day [SD 1.07] from 1.82/day [SD 1.38], p<0.01), which was related to a 59% decline in the number of daily transfers from referral centers (p<0.01), 25% fewer telestroke consultations (p=0.08), and 55% fewer patients presenting directly to our institution by private vehicle (p<0.01) and 29% fewer patients through emergency services (p=0.09). There was no significant change in the monthly number of strokes due to large vessel occlusion (LVO), however the proportion of new LVOs nearly doubled in the COVID-19 period (38% vs. 21%, p=0.01). CONCLUSIONS The observations at our tertiary care center corroborate anecdotal reports that the number of new stroke diagnoses is falling, which seems related to a smaller proportion of patients seeking healthcare services for milder symptoms. These preliminary data warrant validation in larger, multi-center studies.

Abstract
Aims This study determined the impact of the direct oral anticoagulants (DOACs) on the utilisation and expenditure on oral anticoagulants (OACs) in the Irish Community healthcare setting. We also investigated aspects of DOAC prescribing. Methods Using anonymised prescription data from the HSE pharmacy claims database we investigated anticoagulant prescribing over the study period (1/1/2014 - 31/12/2018). Results Some 74,748 patients were being treated with OACs by the year end 2018 an increase of 30,319 over 5 years. Warfarin prescribing fell from 32,751 patients in 2014 to 16,166 by the year end 2018. Apixaban is the most frequently prescribed OAC and annual expenditure on DOACs now exceeds € 51 million. Patients treated with DOACs are older than participants in the pivotal clinical trials and are frequently co-administered interacting drugs. Conclusion The introduction of DOACs has resulted in an overall increase in anticoagulant prescribing, a significant reduction in warfarin usage and a large increase in expenditure.

Abstract
Background: Nurses play a crucial role in the prevention of communicable diseases through the public health immunization programs. Knowledge, attitude and practices of health care providers have significant impact on the vaccine administration and education of adults and parents of children.Objective: The present qualitative study aims to explore the knowledge, attitude and practices of nurses in Qatar before and after the delivery of the immunization-related continuous professional development program.Methods: 10 out of 125 nurses who have completed the training program volunteered to participate in the face-to-face interviews. Data was then collected, transcribed and analysed by the researcher team members.Results: Themes identified from this study: Empowerment, advancing practice and continuing education. Participants felt more confident and had a sense of fulfilment on completion of the education program. Practicing evidenced based skills and methods achieved an outcome of better quality of care, which can directly affect practice. Participants also felt that continuing education allows them to become self-motivated to keep up with new and emerging knowledge. Taken together, our data revealed that continuing professional education immunization-training program was successful in improving the knowledge, attitude and practices of the participants.Conclusions: Continued education beyond traditional baccalaureate nursing programs in order to ensure nurses possess the knowledge to safely handle, teach and administer vaccines is needed.

Abstract
AIM To evaluate the association between the image quality of cancer staging whole-body magnetic resonance imaging (WB-MRI) and patient demographics, distress, and perceived scan burden. MATERIALS AND METHODS A sample of patients recruited prospectively to multicentre trials comparing WB-MRI with standard scans for staging lung and colorectal cancer were invited to complete two questionnaires. The baseline questionnaire, administered at recruitment, collated data on demographics, distress and co-morbidity. The follow-up questionnaire, completed after staging investigations, measured perceived WB-MRI scan burden (scored 1 low to 7 high). WB-MRI anatomical coverage, and technical quality was graded by a radiographic technician and grading combined to categorise the scan as "optimal", "sub-optimal" or "degraded". A radiologist categorised 30 scans to test interobserver agreement. Data were analysed using the chi-square, Fisher's exact, t-tests, and multinomial regression. RESULTS One hundred and fourteen patients were included in the study (53 lung, 61 colorectal; average age 65.3 years, SD=11.8; 66 men [57.9%]). Overall, 45.6% (n=52), scans were classified as "optimal" quality, 39.5% (n=45) "sub-optimal", and 14.9% (n=17) as "degraded". In adjusted analyses, greater deprivation level and higher patient-reported scan burden were both associated with a higher likelihood of having a sub-optimal versus an optimal scan (odds ratio [OR]: 4.465, 95% confidence interval [CI]: 1.454 to 13.709, p=0.009; OR: 1.987, CI: 1.153 to 3.425, p=0.013, respectively). None of the variables predicted the likelihood of having a degraded scan. CONCLUSIONS Deprivation and patients' perceived experience of the WB-MRI are related to image quality. Tailored protocols and individualised patient management before and during WB-MRI may improve image quality.

Abstract
Abstract
Introduction
The Wirral Teletriage Service provides non-urgent clinical support to Wirral Care Homes in order to help avoid unnecessary hospital admissions for their residents. It also aims to provide quicker access to clinical assessment than via NHS 111 and to provide this care in the patient’s residence wherever possible.
Methods
Care homes call the Teletriage service when they have concerns about the health of one of their residents. The Teletriage nurse undertakes a clinical assessment of the resident remotely via Skype. Care Homes have been provided with a secure NHS email address to facilitate secure sharing of data. They have also been provided with iPads and training for their staff. After being assessed by Teletriage, residents are signposted to the most appropriate care pathway for their needs.
Results
76 Care Homes have signed up to the service. On average, the Teletriage Service receives 300-400 calls a month. In an 18 month period, the number of calls to NHS 111 have reduced by 76%. Out of all the calls to Teletriage, 22% of patients were managed by the Teletriage team with no onward referral, 57% were managed via community services e.g GPs, Community Geriatricians, and 10% were referred to the ambulance service. Emergency Health Care Plans (EHCPs), Preferred Priorities of Care and EOL (End of Life) wishes are taken into account.
Conclusions
The Teletriage project has reduced the number of phone calls to NHS 111 and the ambulance service, and subsequently has reduced the number of patients conveyed to hospital by 12%. The Teletriage nurses work very closely with various community services as well as GPs, NWAS and Community Geriatricians. The ongoing training and education provided to the Care Home Staff means that overall there has been good engagement with the project from the majority of the Wirral Care Homes.

Abstract
Abstract
Background
Northumbria Healthcare NHS Foundation Trust provides services to more than 500,000 residents in the North-East of England across multiple sites.
Local problem
Outpatient services for older people across Northumbria include specialist (eg falls) and generic clinics with differing referral routes, demands and waiting times. Referrals derive from primary care, emergency services and elsewhere; some are complex patients requiring a comprehensive geriatric assessment (CGA). Existing pathways led to variable waits for clinics, duplication and delays.
Aim was to improve the timeliness, efficiency and access to appropriate assessment first time.
Methods
We adopted a Clinical Microsystems approach (Sheffield Microsystems Coaching Academy) for improvement. Main components were team coaching, weekly “Big Room” meeting of involved staff to share understanding of current process, agree change ideas, and test these with multiple plan, do, study, act (PDSA) cycles. Impacts of each PDSA cycle were discussed in Big Room, leading to refinement of the pathway.
Interventions
Results: PDSA interventions were tested over 6 months: Development of a single triage systemCGA clinic for frail older patients.Development of shared documentation for CGA.Improved cycle and lead times for assessment
Conclusions
Our quality improvement work supported the development and implementation of a new referral triage process with CGA assessment for complex frail patients. The change has reduced patient wait times, provided early intervention and reduced duplication. Work is ongoing to determine impact on patient satisfaction and time to discharge from clinic. The approach taken by this project could be applied elsewhere to improve outpatient referral processes.
