Abstract
Study question Are pregnant women in the community with confirmed diagnosis of SARS-CoV–2 infection, at increased risk of an early miscarriage? Summary answer Women diagnosed with COVID–19 in their first trimester were not at increased risk of an early miscarriage. What is known already: In the earliest stages of the pandemic, the Human Fertilisation and Embryology Authority and the European Society of Human Reproduction and Embryology, independently advised against starting assisted reproductive treatments. At the time of this recommendation, among other reasons, there were concerns about the complications of SARS-CoV–2 during pregnancy and the potential for vertical transmission. We now having growing evidence that pregnant women are at an increased risk of severe illness along with higher rates of preterm births in those with severe acute respiratory syndrome. However, data on the impact of community infections of SARS-CoV–2 in early pregnancy has been sparse. Study design, size, duration This is an online survey study undertaken in the UK between May and November 2020. Pregnant women at any stage in their pregnancy were invited to participate in the study. Study participants were asked to complete online surveys at the end of each trimester. 10, 430 women were recruited to take part in the study. Participants/materials, setting, methods: We analysed pregnancy outcomes from women who were under 13 weeks gestation at the time of registration. We compared miscarriage rates among women with a confirmed diagnosis of SARS-CoV–2 infection to healthy controls. Those in the control group had not been diagnosed with or had symptoms of SARS-CoV–2 infection nor did they have any household contacts that were diagnosed with or had symptoms of SARS-CoV–2 infection. Main results and the role of chance 10, 430 pregnant women were recruited to participate in the study. 2934 were under 13 weeks gestation at the time of registration. The median age was 32.6 [IQR 29.8–35.6]. The median gestational age at registration was 8 weeks [IQR [6–10]. 246 women reported a miscarriage before 13 weeks of gestation. The overall miscarriage rate before 13 weeks of gestation was 8.4% (95% CI 7.3%–9.4%). 68 women reported a confirmed diagnosis of SARS-CoV–2 infection in their first trimester. The overall rate of confirmed SARS-CoV–2 infections in the first trimester was 2.3% (95% CI 1.8–2.9%). 3/68 (4.4%) were asymptomatic. Among those reporting symptoms, the commonest symptoms were fatigue (82%), headache (69%) and loss of smell/taste (69%). Only 38% of those with a confirmed diagnosis reported a fever. None of the 68 women with confirmed diagnosis of SARS-CoV–2 infection were hospitalised. The rate of miscarriage before 13 weeks of gestation in women who were diagnosed with SARS-CoV–2 infections was not significantly higher compared to healthy controls (11.8% versus 9.3%, p = 0.35). A further 35 women had household contacts with confirmed SARS-CoV–2 infection although they themselves had not been diagnosed. No miscarriages were reported in this group. Limitations, reasons for caution None of the 68 patients diagnosed with SARS-CoV–2 were hospitalised. We do not know whether the rate of miscarriage among hospitalised women with SARS-CoV–2 infection is the same as those with community infections. Wider implications of the findings: The overall rate of miscarriage during the pandemic was not higher than rates occurring outside of the pandemic. The rate of miscarriage among women diagnosed with SARS-CoV–2 infection was not significantly higher compared to healthy controls. This data can be used to counsel women planning a pregnancy during this pandemic Trial registration number Not applicable

Abstract
Study question
What are a woman’s contraceptive needs after successful in vitro fertilisation (IVF) pregnancy? and how should services respond to help prevent unintended pregnancies?
Summary answer
Women who have IVF pregnancies require tailored, postnatal contraception counselling. Services must provide evidence-based information about the risks of spontaneous conception to engage them effectively.
What is known already
Women undergoing IVF are an increasingly heterogeneous group with a wide range of causative subfertility factors. Furthermore, increasingly, women are accessing treatment primarily for reasons other than subfertility. The evidence relating to rates of spontaneous conception post assisted conception varies widely according to population, cause of subfertility, type and outcome of fertility treatment and length of follow-up. A recent large retrospective UK cohort study estimated the treatment-independent live birth rate after IVF live birth over 5 year follow up as 15% [https://doi.org/10.1093/humrep/dez099]. We aim to explore the experiences and views about contraception among this diverse group of women.
Study design, size, duration
A qualitative study of the views of women who have had spontaneous pregnancies after successful IVF was conducted in September/October 2020. A qualitative approach of in-depth interviews was chosen to allow exploration of individual experiences in an area not much studied previously. The sample consisted of twenty interviewees from around the UK.
Participants/materials, setting, methods
Purposive and snowballing sampling methods were used with eligible participants recruited from a range of sources including social media and peer networks. The sample included a wide range of spontaneous pregnancy outcomes after successful IVF, including single and multiple livebirths, miscarriage, ectopic pregnancy and termination of pregnancy. The framework method was used for analysis using NVivo12 software.
Main results and the role of chance
Contraceptive choices were subject to a complex and dynamic interaction of influencing factors including i) beliefs regarding their own subfertility, ii) desire for more children and iii) their views on contraception. After IVF pregnancy, the majority of women (n = 15) used no contraception or ineffective methods (inconsistent condom use or withdrawal) before their next pregnancy with only two women using hormonal methods (progesterone-only pill). Spontaneous pregnancy was not universally welcomed in this group and the inter-pregnancy intervals were often short (n = 15, less than 18 months) or very short (n = 6, less than 12 months). After subsequent spontaneous pregnancy, use of contraception and the most effective (long-acting reversible) methods remained low. Women held persistent beliefs regarding their subfertility despite subsequent spontaneous pregnancy (or pregnancies). Women associated aspects of the IVF process (e.g. need for multiple cycles, low numbers of eggs collected etc.) with a sense of personal failure, despite an ultimately “successful” outcome resulting in livebirth. This may contribute to or reinforce their self-belief in subfertility. Other specific barriers to contraception use, in women having IVF, included lack of knowledge of the likelihood of spontaneous pregnancy, lack of contraceptive experience and inherent incentives towards shorter inter-pregnancy intervals.
Limitations, reasons for caution
There is potential recall bias with some women recalling experiences associated with IVF treatment more than ten years ago. However our sample included women who were currently pregnant as well as women who were further towards the end of their reproductive life to capture a range of experiences.
Wider implications of the findings: The contraceptive needs of women having IVF pregnancies are being overlooked. Fertility services should take responsibility for providing accurate information on the risks of subsequent spontaneous pregnancy in this population. Maternity and community healthcare professionals must address women’s perceptions of their fertility in order to engage them in contraception counselling.

Abstract
Abstract
Study question
What are the major problems faced by embryologists at 1) Clinic level, 2) Professional level, 3) Personal level, and 4) What are their career goals?
Summary answer
Embryologists, essential professionals of Fertility Centres, are less satisfied in many quantifiable aspects, but they love their profession and have many aspirational goals.
What is known already
IVF success depends in part on embryologists’ skills. The need to recognize clinical embryology as a specialty and clinical embryologists’ educational level, responsibilities, and workload have been addressed by a few national societies. However, data are lacking from the embryologists’ viewpoint at a global level about their profession. Qualitative data-analysis methods provide thick, rich descriptions of subjects’ thoughts, feelings, and lived experiences but can be time-consuming, labor-intensive, and prone to bias.
Study design, size, duration
A questionnaire was prepared using SurveyMonkey online software (SurveyMonkey, Inc., USA) and distributed to IVF lab professionals through embryology societies, online social media, and email databases. The questionnaire consisted of open-ended questions focused on identifying problems faced by embryologists at the clinic, in the profession, and in a personal level, as well as questions about their career outlook. The survey was active from May 2016 until February 2017. From 73 countries, 720 responses were obtained.
Participants/materials, setting, methods
Using natural language processing (NLP), the top 15 most frequently used keywords were identified and correlated with each other. Stronger correlation (≥0.5) between semantically similar words expressing a strong signal from each answer, and their usage was further analyzed for positive versus negative sentiment. By normalizing the frequency of positive/negative samples for each keyword as a percentage, “sentiment wheels” were produced, identifying the key concepts that respondents answered and quantifying how they felt about them.
Main results and the role of chance
The responses received were from 80% private, 17% public and 3% other ART settings distributed all over the world. From the embryologists’ viewpoints reported and after the NLP processing it was shown that the common topics related to strong negative sentiments were: embryologists’ remuneration (0.6) at the Clinic level; certification (0.7), recognition (0.5), respect (0.5), learn (0.5) and experience (0.5) at the Professional level; and remuneration (0.7), emotional (0.5) dealing (0.5) at the Personal level. Renumeration was reported and strongly related to embryologists’ viewpoint at both the clinic and personal level in combination with the need for certification, recognition and ongoing development at the Professional level. Moreover, the NLP processing demonstrated that the common topics on career goal analysis related to strong positive sentiments were: teaching (0.7), education (0.7), and continuation (0.5) all three topics are compatible with a professional orientation open to ongoing development and practice advancement. The NLP and the manual data analysis project an image of the typical embryologist as a knowledge seeking professional who is deeply dedicated to the job but feels the need for professional development and suffers some lack of recognition and feels in some cases not fairly treated as an employee.
Limitations, reasons for caution
The data obtained is limited. Only one natural language processing model was used to analyze the results. Different analysts using other methods may have different results. For these reasons, the results should be interpreted with caution.
Wider implications of the findings: It is important to focus on the lab as an organization and not just a service for the patients in treatment at the moment. The NLP results ultimately obtained may help streamline professional satisfaction efforts, and guide future quality management strategies

Abstract
Abstract
Study question
Do AI models used to assess embryo viability (based on pregnancy outcome) also correlate with known embryo quality measures such as ploidy status?
Summary answer
An AI for embryo viability assessment correlated with ploidy status, and with karyotypic features of aneuploidy, supporting its use for embryo selection.
What is known already
One factor that can influence pregnancy success is the genetic status of the embryo. PGT-A is commonly used to test for embryo ploidy, with the aim of identifying karyotypically normal embryos (euploid embryos), for preferential transfer. There is evidence suggesting that transfer of euploid embryos produces favorable clinical outcomes over aneuploid embryos.
Given the AI model was trained to evaluate clinical pregnancy, it was hypothesized that the score might also correlate with ploidy status, and with different types of aneuploidies. Little is known about morphological correlations with embryo ploidy status, so we also sought to explore this relationship.
Study design, size, duration
This study involved analysis of a retrospective dataset of single static Day 5 embryo (blastocyst) images with associated PGT-A results and AI viability scores. The dataset comprised images of 5,469 embryos from 2,615 consecutive patients treated at five US IVF clinics between February 2015 and April 2020. The AI was trained on thousands of Day 5 embryo images from multiple IVF laboratories in multiple countries, but was not trained on data used in this study.
Participants/materials, setting, methods
Average patient age was 36.2 years, and average embryo cohort size was 2.1/patient. PGT-A analysis was performed on embryos at time of evaluation. The dataset comprised 3,251 (59.4%) euploid embryos, 1,815 (33.2%) aneuploid embryos, and 403 (7.4%) mosaic embryos. The AI was retrospectively used to provide a score between 0 (predicted non-viable) and 10 (predicted viable) for each image. Correlation between the AI viability score and euploid, mosaic and aneuploid embryos was then assessed.
Main results and the role of chance
Results showed a statistically significant correlation between AI viability score and PGT-A outcome, consistent with a relationship between pregnancy outcome and ploidy status. The average score for euploid embryos was 8.20, which was significantly higher than the average score for aneuploid embryos of 7.80 (p < 0.0001).
There was a significant linear increase in confidence score from full aneuploid embryos, through mosaic embryos (average score 7.97), to full euploid embryos (mosaic threshold of 20–80%). High mosaic embryos tended to have a lower average score (7.60) than low mosaic embryos (7.96), consistent with correlation of viability (pregnancy outcome) with the degree of mosaicism. AI viability score also correlated with ploidy features believed to affect pregnancy outcomes. Trisomic changes had higher average scores than monosomic changes. Segmental changes had higher average scores than full gain or loss. The AI score differentiated euploid from aneuploid status more efficiently in embryos with poorer morphology than those with good morphology.
Whilst there was an evident correlation between pregnancy outcome and ploidy status, the AI was only weakly predictive of euploidy, with an accuracy of 57.3% using an AI viability score threshold of 7.5/10.This suggests pregnancy-related morphological features are somewhat correlated with embryo ploidy, but not completely.
Limitations, reasons for caution
The PGT-A technique is held to have some limitations for evaluating ploidy status, therefore it would be of benefit to perform additional confirmatory studies on independent datasets. It would be of interest to conduct prospective studies evaluating correlations between the AI’s evaluation of morphology and pregnancy outcome with ploidy status.
Wider implications of the findings: The AI score correlated with genetic features of embryos that are known to correlate with pregnancy, which further supports the efficacy and use of AI for embryo viability assessment. The AI identified morphological features that are somewhat predictive of ploidy status, with potential application to embryos of poorer Gardner score.

Abstract
Objective To report the temporal and spatial distribution of rainbow lorikeets presenting with lorikeet paralysis syndrome (LPS) and their clinicopathologic and pathologic findings, exposure to toxins, and response to treatment. Methods Records of lorikeets admitted in 2017 and 2018 to facilities in south‐east Queensland (QLD) were reviewed and LPS and non‐LPS cases were mapped and their distribution compared. Plasma biochemistries and complete blood counts were done on 20 representative lorikeets from south‐east QLD and Grafton, New South Wales (NSW). Tissues from 28 lorikeets were examined histologically. Samples were tested for pesticides (n = 19), toxic elements (n = 23), botulism (n = 15) and alcohol (n = 5). Results LPS occurred in warmer months. Affected lorikeets were found across south‐east QLD. Hotspots were identified in Brisbane and the Sunshine Coast. Lorikeets had a heterophilic leucocytosis, elevated muscle enzymes, uric acid and sodium and chloride. Specific lesions were not found. Exposure to cadmium was common in LPS and non‐LPS lorikeets. Treated lorikeets had a 60–93% See Table 2 depending on severity of signs. Clinical significance The primary differential diagnosis for lorikeets presenting with lower motor neuron signs during spring, summer and autumn in northern NSW and south‐east Queensland should be LPS. With supportive care, prognosis is fair to good.

Abstract
Importance Intracerebral hemorrhage (ICH) is a devastating stroke type that lacks effective treatments. An imaging biomarker of ICH expansion-the computed tomography (CT) angiography spot sign-may identify a subgroup that could benefit from hemostatic therapy. Objective To investigate whether recombinant activated coagulation factor VII (rFVIIa) reduces hemorrhage expansion among patients with spot sign-positive ICH. Design, Setting, and Participants In parallel investigator-initiated, multicenter, double-blind, placebo-controlled randomized clinical trials in Canada ("Spot Sign" Selection of Intracerebral Hemorrhage to Guide Hemostatic Therapy [SPOTLIGHT]) and the United States (The Spot Sign for Predicting and Treating ICH Growth Study [STOP-IT]) with harmonized protocols and a preplanned individual patient-level pooled analysis, patients presenting to the emergency department with an acute primary spontaneous ICH and a spot sign on CT angiography were recruited. Data were collected from November 2010 to May 2016. Data were analyzed from November 2016 to May 2017. Interventions Eligible patients were randomly assigned 80 μg/kg of intravenous rFVIIa or placebo as soon as possible within 6.5 hours of stroke onset. Main Outcomes and Measures Head CT at 24 hours assessed parenchymal ICH volume expansion from baseline (primary outcome) and total (ie, parenchymal plus intraventricular) hemorrhage volume expansion (secondary outcome). The pooled analysis compared hemorrhage expansion between groups by analyzing 24-hour volumes in a linear regression model adjusted for baseline volumes, time from stroke onset to treatment, and trial. Results Of the 69 included patients, 35 (51%) were male, and the median (interquartile range [IQR]) age was 70 (59-80) years. Baseline median (IQR) ICH volumes were 16.3 (9.6-39.2) mL in the rFVIIa group and 20.4 (8.6-32.6) mL in the placebo group. Median (IQR) time from CT to treatment was 71 (57-96) minutes, and the median (IQR) time from stroke onset to treatment was 178 (138-197) minutes. The median (IQR) increase in ICH volume from baseline to 24 hours was small in both the rFVIIa group (2.5 [0-10.2] mL) and placebo group (2.6 [0-6.6] mL). After adjustment, there was no difference between groups on measures of ICH or total hemorrhage expansion. At 90 days, 9 of 30 patients in the rFVIIa group and 13 of 34 in the placebo group had died or were severely disabled (P = .60). Conclusions and Relevance Among patients with spot sign-positive ICH treated a median of about 3 hours from stroke onset, rFVIIa did not significantly improve radiographic or clinical outcomes. Trial Registration ClinicalTrials.gov identifier: NCT01359202 and NCT00810888.

Abstract
Background:Osteoarthritis (OA) is a common disease that varies in severity among patients. A standardized definition to classify patients into different severity levels is lacking, however, due to the disease’s complex pathogenesis and presentation. Prior studies have shown associations between pain severity and higher healthcare resource utilization (HRU) and costs. We investigated an association between pain severity and higher healthcare resource utilization by examining the use of specific OA-related treatments across pain intensity levels in a large, integrated health system’s OA population over an 18-year period.Objectives:Our aim was to compare use of medications and other treatments among OA patients experiencing mild, moderate, or severe pain.Methods:This was a retrospective study of electronic health records from 2001 to 2018 at Geisinger, an integrated health system in Pennsylvania. Patients were included with a diagnosis code for OA (ICD-9: 715.*, ICD-10 M15-19) on a problem list or encounter or an OA-specific procedure (hip or knee replacement, arthroscopy or injection). We examined pain scores (0-10 scale, with 10 being worst pain) taken after the first OA diagnosis date and defined pain episodes starting on the pain score’s date and lasting for 90 days. If a new pain score was measured before 90 days elapsed, the episode was extended for an additional 90 days, with this process repeated as necessary. Each episode was categorized as mild (pain score 0-3), moderate (4-6), or severe (7-10) based on initial score, and patients could contribute multiple episodes to the analysis. Descriptive statistics were used to quantify treatment utilization during each patients’ mild, moderate and severe episodes. Percentages of patients who had any use of 10 medication types (tramadol, non-tramadol opioids, nonsteroidal anti-inflammatory drugs (NSAIDs), injectable corticosteroids, acetaminophen, salicylates, duloxetine, homeopathic medications, other topical medications, and other over-the-counter (OTC) medications were compared across pain episode types. Percentages of patients with knee or hip surgeries, spine or joint imaging procedures (x-ray, computed tomography or magnetic resonance) and consults to OA-related care (pain management, orthopedics or physical medicine and rehabilitation) were also compared. All analyses used logistic regression with p-values <0.05 considered significant.Results:We identified 290,897 patients with OA, representing 34% of the health system population in 2018; 58% were female with mean age of 49 years and mean BMI of 30.5 kg/m2. A total of 801,144 pain episodes were defined, with 75% of patients having at least one pain score. The two most frequently occurring pain scores were 0 (17%) and 5 (13%), and pain episodes were classified as 43% mild, 32% moderate and 25% severe. Significantly higher percentages of patients used certain medication types (NSAIDs, injectable corticosteroids, non-tramadol opioid, duloxetine) in both moderate and severe pain episodes as compared to mild episodes, but other medication types were less likely to be used as pain severity increased (acetaminophen, salicylates, homeopathic medications, other OTC medications). Knee or hip surgeries, imaging, and consults to OA-related specialists were all consistently significantly more likely to occur in patients during moderate or severe pain episodes versus mild episodes (relative risk ratios of 1.76, 1.25 and 1.35 for moderate vs mild, respectively, and 2.00, 1.44 and 1.46 for severe vs mild, all p-values <0.05).Conclusion:While pain is generally recognized to be a subjective measure that could be influenced by other unmeasured factors and can be confounded with treatment effectiveness, it is nevertheless the primary symptom of OA. It is important to understand the relationship between pain intensity and treatment utilization, and our results support an overall association between pain and utilization but provide new details on the extent to which it depends on specific utilization type.Acknowledgements:Pfizer and Eli Lilly and Company for sponsoring this study.Disclosure of Interests:Jove Graham Grant/research support from: I am an employee of Geisinger which received financial support from Pfizer and Eli Lilly and Company in connection with the development of this abstract, Tonia Novosat Grant/research support from: I am an employee of Geisinger which received financial support from Pfizer and Eli Lilly and Company in connection with the development of this abstract, Haiyan Sun Grant/research support from: I am an employee of Geisinger which received financial support from Pfizer and Eli Lilly and Company in connection with the development of this abstract, Brian Piper Grant/research support from: I am an employee of Geisinger which received financial support from Pfizer and Eli Lilly and Company in connection with the development of this abstract, Joseph Boscarino Grant/research support from: I am an employee of Geisinger which received financial support from Pfizer and Eli Lilly and Company in connection with the development of this abstract, Vanessa Duboski Grant/research support from: I am an employee of Geisinger which received financial support from Pfizer and Eli Lilly and Company in connection with the development of this abstract, Melissa Kern Grant/research support from: I am an employee of Geisinger which received financial support from Pfizer and Eli Lilly and Company in connection with the development of this abstract, Eric Wright Grant/research support from: I am an employee of Geisinger which received financial support from Pfizer and Eli Lilly and Company in connection with the development of this abstract, Rebecca Robinson Shareholder of: Eli Lilly & Co., Employee of: Eli Lilly & Co., Edward Casey Shareholder of: Pfizer, Inc., Paid instructor for: As an employee of Pfizer, Inc. this is part of my role., Employee of: Pfizer, Inc., Craig Beck Shareholder of: Pfizer, Inc., Employee of: Pfizer, Inc., Jerry Hall Shareholder of: Eli Lilly & Co., Employee of: Eli Lilly & Co., Patricia Schepman Shareholder of: Pfizer, Inc., Employee of: Pfizer, Inc.

Abstract
Background:The COVID-19 pandemic is expected to have impacted patient management on a global level. However, the degree of impact on patient management and prescribing strategy in the fields of rheumatology, dermatology and gastroenterology is unclear.Objectives:Assess the impact of COVID-19 on patient management and prescribing strategy across the EU and US, as described by rheumatologists, dermatologists, and gastroenterologists.Methods:Data were drawn from physician surveys in France, Germany, Italy, Spain, UK and US between July and December 2020. Physicians completed an online or telephone survey assessing how COVID-19 has impacted type and frequency of consultations; choice and prescription of medication.Results:847 physicians took part; 355 rheumatologists, 200 dermatologists (Germany, Spain, UK, and US only), and 282 gastroenterologists. As a result of COVID-19, most physicians stated they have moved at least some patients to video or telephone consultations (70% rheumatologists; 55% dermatologists; 60% gastroenterologists) and reduced overall frequency of consultations with patients (59% rheumatologists; 64% dermatologists; 51% gastroenterologists) (Table 1).35% of rheumatologists, 22% of dermatologists, and 14% of gastroenterologists described COVID-19 as changing the way they choose and prescribe medication, with differences observed between countries (Figure 1). Of those who stated they have made medication changes, rheumatologists stated changing medication to self-administration (62%) and not starting new patients on an advanced therapy (biologic DMARD or targeted synthetic DMARD) (58%) as most frequent. Dermatologists stated changes include changing treatment to more COVID-appropriate treatment (71%) and prescribing repeat prescriptions more regularly without consultation (56%). Gastroenterologists stated changes include changing medication to self-administration (55%) and prescribing a longer course of medication (48%).Comparing across countries, for all specialties, the greatest changes were observed in the UK followed by Spain, with least changes in Germany and Italy.Conclusion:There have been changes in the process of how healthcare is delivered, although treatment prescription was impacted to a lesser extent than consultation type and frequency. This varies across geographies, which may be due to differences in reported prevalence of COVID-19. Differences are also observed across specialities, which may be due to guidance received from specialty bodies. It is unknown what the long-term impact of changes in the management of patients due to COVID-19 will be on patient outcomes, satisfaction, engagement and adherence, and further research is needed.Table 1.Rheumatologist, Dermatologist, and Gastroenterologist described impact on patient management, by countryGlobal(n=847)France(n=90)Germany(n=168)Italy(n=122)Spain(n=161)UK(n=133)US(n=163)Rheumatologistsn=365n=50n=58n=59n=57n=50n=81Moving to video/telephone consultation70%70% 36%47%86%94%84%Fewer visits for individual patients (reduced visiting schedule)59%80%0%41%96%76%65%Dermatologistsn=200-n=50-n=50n=50n=50Moving to video/telephone consultation55%-40%-58%66%56%Fewer visits for individual patients (reduced visiting schedule)64%-60%-54%72%72%Gastroenterologistsn=282n=40n=60n=63n=54n=33n=32Moving to video/telephone consultation60%63%18%54%83%100%69%Fewer visits for individual patients (reduced visiting schedule)51%35%43%51%43%79%69%Figure 1.Proportion of rheumatologists, dermatologists, and gastroenterologists reporting changing the way they choose and prescribe medication as a result of COVID-19Disclosure of Interests:None declared.

Abstract
OBJECTIVES To review the cause, management and outcome in cats with septic peritonitis within the United Kingdom (2008 to 2018) and to identify if previously identified prognostic factors were associated with survival in this population. MATERIALS AND METHODS Clinical records from 10 referral hospitals in United Kingdom were reviewed. Data collected included signalment, clinicopathological data and management techniques. Serum albumin, glucose, lactate and ionised calcium concentration; presence of intraoperative hypotension and correct empirical antibiosis were analysed via logistic regression for association with survival. RESULTS Ninety-five cats were included. The overall survival rate was 66%. Lethargy (89%) and anorexia (75%) were the most common clinical signs, with abdominal pain and vomiting in 44% and 27% of cases, respectively. Gastro-intestinal leakage was the most common source of contamination. The presence of an abdominal mass on clinical examination was not strongly predictive of the presence of neoplasia on histology and did not confer a worse prognosis. Cats presenting with dehiscence of a previous enterotomy/enterectomy did not have a worse prognosis than those presenting with other aetologies. Intraoperative hypotension (adjusted odds ratio 0.173, 95% confidence intervals 0.034 to 0.866, P=0.033) was associated with non-survival. Cats that survived beyond 1 day postoperatively had an improved likelihood of survival (87.5%). All cats that survived beyond 6 days were successfully discharged. CLINICAL SIGNIFICANCE This study describes the largest group of cats with septic peritonitis with an overall survival rate of 66%. The presence of an abdominal mass on clinical examination or having dehiscence of a previous gastrointestinal surgery did not confer a worse prognosis.

Abstract
AIMS Existing methods for the identification of the subspecies of Xylella fastidiosa are time-consuming which can lead to delays in diagnosis and the associated plant health response to outbreaks and interceptions. METHODS AND RESULTS Diagnostic markers were identified using a comparative genomics approach to allow fine differentiation of the very closely related subspecies. Five qPCR assays were designed to allow specific detection of X. fastidiosa subsp. fastidiosa, X. fastidiosa subsp. multiplex, X. fastidiosa subsp. pauca, X. fastidiosa subsp. morus and X. fastidiosa subsp. sandyi. All assays were validated according to the European and Mediterranean Plant Protection Organisation (EPPO) standard PM7/98(2). CONCLUSIONS All of the assays were shown to be specific to the target subspecies and all the assays could be used to detect femtogram quantities of X. fastidiosa DNA. SIGNIFICANCE AND IMPACT OF THE STUDY At present, diagnosing the subspecies of X. fastidiosa requires multiple conventional PCR assays (although only available for three of the five subspecies) or multi-locus sequence typing which takes several days. By comparison, the new assays provide a substantial reduction in the turnaround time for direct identification to the subspecies level in as little as 75 min.

Abstract
In order to support women and their partners to improve their health before pregnancy, we need to be able to identify who is likely to become pregnant within a given timeframe so that interventions can be targeted accordingly. There is no agreed, predictive tool currently available to do this. This presentation will describe the different ways of conceptualising the preconception population and how these populations can be identified to inform intervention delivery and development. We will overview what is known about the preferences of women and men with regards to preconception health services, with a particular focus on digital innovations, and will discuss how the effectiveness of preconception health interventions can be evaluated to contribute to the evidence base.

Abstract
OBJECTIVES Although several studies have examined the gap in healthcare use between indigenous and non-indigenous people, empirical evidence on inequity in healthcare use within indigenous populations is limited. This study aims to fill this gap in the literature by investigating income-related inequity (unequal use for equal need) in healthcare use among indigenous Australians living in non-remote areas. STUDY DESIGN This is a cross-sectional study. METHODS This study used data from the Australian Aboriginal and Torres Strait Islander Health Survey, 2012-13. Logistic regression analysis was used to determine the association of income with the probability of a general practitioner (GP) visit, a specialist visit and inpatient admission. The horizontal inequity (HI) index and decomposition analysis were also used to quantify and explain inequity in healthcare use. RESULTS No consistent association was found between income and the probability of GP visit or inpatient admission after controlling for health need. However, the likelihood of visiting a specialist was about three times (odds ratio = 2.96, P = 0.028) higher for the richest compared with the poorest population subgroups. The inequity index was 0.016 (P < 0.001), indicating a pro-rich inequity for the probability of visiting a specialist. Income inequality, unequal distribution of private health insurance and inequality in education were the main factors explaining the pro-rich inequity in specialist utilisation. CONCLUSIONS Although there was no income-related inequity in GP visits or inpatient admissions, wealthier indigenous Australians had a higher probability of visiting a specialist than their poorer counterparts, after adjusting for need. Specific policies and initiatives are required to address the inequity faced by low-income indigenous people in Australia.

Abstract
BACKGROUND Young people with 22q11.2 deletion syndrome (22q11.2DS) are at high risk for neurodevelopmental disorders. Sleep problems may play a role in this risk but their prevalence, nature and links to psychopathology and cognitive function remain undescribed in this population. METHOD Sleep problems, psychopathology, developmental coordination and cognitive function were assessed in 140 young people with 22q11.2DS (mean age = 10.1, s.d. = 2.46) and 65 unaffected sibling controls (mean age = 10.8, s.d.SD = 2.26). Primary carers completed questionnaires screening for the children's developmental coordination and autism spectrum disorder. RESULTS Sleep problems were identified in 60% of young people with 22q11.2DS compared to 23% of sibling controls (OR 5.00, p < 0.001). Two patterns best-described sleep problems in 22q11.2DS: restless sleep and insomnia. Restless sleep was linked to increased ADHD symptoms (OR 1.16, p < 0.001) and impaired executive function (OR 0.975, p = 0.013). Both patterns were associated with elevated symptoms of anxiety disorder (restless sleep: OR 1.10, p = 0.006 and insomnia: OR 1.07, p = 0.045) and developmental coordination disorder (OR 0.968, p = 0.0023, and OR 0.955, p = 0.009). The insomnia pattern was also linked to elevated conduct disorder symptoms (OR 1.53, p = 0.020). CONCLUSIONS Clinicians and carers should be aware that sleep problems are common in 22q11.2DS and index psychiatric risk, cognitive deficits and motor coordination problems. Future studies should explore the physiology of sleep and the links with the neurodevelopment in these young people.

Abstract
Satellite tracking of endangered or threatened animals can facilitate informed conservation by revealing priority areas for their protection. Basking sharks Cetorhinus maximus (n = 11) were tagged during the summers of 2013, 2015, 2016 and 2017 in the Isle of Man (IoM; median tracking duration 378 d, range: 89-804 d; median minimum straight-line distance travelled 541 km, range: 170-10406 km). Tracking revealed 3 movement patterns: (1) coastal movements within IoM and Irish waters, (2) summer northward movements to Scotland and (3) international movements to Morocco and Norway. One tagged shark was bycaught and released alive in the Celtic Sea. Basking sharks displayed inter-annual site fidelity to the Irish Sea (n = 3), a Marine Nature Reserve (MNR) in IoM waters (n = 1), and Moroccan waters (n = 1). Core distribution areas (50% kernel density estimation) of 5 satellite tracked sharks in IoM waters were compared with 3902 public sightings between 2005 and 2017, highlighting west and south coast hotspots. Location data gathered from satellite tagging broadly correspond to the current boundaries of MNRs in IoM waters. However, minor modifications of some MNR boundaries would incorporate ~20% more satellite tracking location data from this study, and protective measures for basking sharks in IoM waters could further aid conservation of the species at local, regional and international scales. We also show the first documented movement of a basking shark from the British Isles to Norway, and the longest ever track for a tagged basking shark (2 yr and 2 mo, 804 d).

Abstract
ObjectivesThe objective of this research was to utilize thermal imaging technology to estimate body temperature, so that an early stage of BRD can be detected.Materials and MethodsNinety-two steers were restrained in a squeeze chute that is housed in an indoor handling facility on 6 separate occasions. At least one image was taken of each side of the head using a thermal infrared camera (FLIR E8 WiFi, FLIR, Wilsonville, OR). The distance at which the images were taken was approximately 1 m from the steer. The rectal temperature was used as the control method to compare thermal imaging data. After thermal image acquisition, images were analyzed using the FLIR ResearchIR Max software (v. 4.40.8.28, FLIR, Wilsonville, OR), with the regions of interest being the eye and nasal cavity.ResultsThe analysis focused on minimum (MIN), maximum (MAX), mean, standard deviation (SD), and range of temperatures in the regions of interest. The REG procedure in SAS (v. 9.4, SAS Institute, Inc., Cary, NC) was used to perform stepwise regression to predict rectal temperature from the outdoor temperature (OTEMP) and all imaging features. When OTEMP was greater than –17.8°C, the regression model contained OTEMP, left nasal MAX, left nasal SD, and left eye MAX temperature and right eye temperature range, with an R2 of 0.24. When OTEMP was above freezing (0°C), the regression model contained left nasal temperature range, right eye temperature range, and average nasal mean temperature, with an R2 increase to 0.50. When using all data, the regression model fit left nasal MAX, right nasal MIN, average nasal mean, and left eye MAX temperatures and right eye temperature range, with an R2 of 0.08. These results show that thermal imaging technology has higher prediction accuracy in warmer temperature ranges than extreme cold conditions.ConclusionMore validation research on this thermal imaging technology needs to be conducted at warmer temperatures since all the current data was collected on cold winter days and a large portion of U.S. cattle are reared in more temperate and warmer areas than North Dakota such as Nebraska, Kansas, Texas, Oklahoma, and Florida. Overall, these results show promise for using thermal imaging technology to help detect BRD in an earlier stage by detecting fever before other clinical signs of BRD are present.

Abstract
OBJECTIVES To investigate association between neutering and early-onset urinary incontinence in bitches under primary veterinary care in the UK. MATERIALS AND METHODS A retrospective cohort study of bitches within VetCompass born between January 1, 2010 and December 31, 2012 that were followed until March 31, 2018. The clinical records were automatically searched and manually validated for incontinence cases. Incidence risk and rate over the study period were calculated. Cox regression modelling separately evaluated the hazard of urinary incontinence and association with neutering: (1) from the date of birth for all bitches, both neutered and entire; and, (2) from the date of neutering for the neutered subset. Other variables considered included breed, bodyweight and veterinary practice group. RESULTS Overall, 492 bitches were identified with early-onset urinary incontinence from a total of 72,971 included in the study period. Incidence risk was 0.68% (95% confidence intervals 0.62 to 0.74), while incidence rate increased with age. After accounting for confounding factors, increased hazard of early-onset urinary incontinence was identified in: (1) neutered bitches, with the effect increasing with age; and, (2) bitches neutered before 6 months, within the first 2 years following neutering. In both models, increased hazard was additionally associated with increasing bodyweight and breed. CLINICAL SIGNIFICANCE Neutering itself and early-age neutering (<6 months) are major risk factors for early-onset urinary incontinence. These results should be taken into account in making evidence-based recommendations on neutering and its timing.

Abstract
Abstract
Introduction
Despite recent improvements in management, infective endocarditis remains associated with high morbidity and mortality. Over the last few decades, several factors have impacted on both the incidence and outcomes following infective endocarditis.
Purpose
Using a national linkage approach, we describe the changing age- and sex-stratified incidence and outcomes of infective endocarditis in Scotland over the last 25 years.
Methods
We conducted a consecutive retrospective individual patient linkage study across multiple national databases. Using data extracted from the Scottish hospital discharge dataset held by the Information Services Division of NHS National Services Scotland, we extracted episodes for all patients aged 20 years or older who were admitted with infective endocarditis between January 1, 1990, and December 31, 2014 in Scotland, UK. Patient episodes with infective endocarditis were linked to national prescribing and microbiology databases. The primary outcome was 1-year mortality following the index presentation. Generalised additive models were constructed to estimate the crude and age- and sex-stratified incidence rates (using a poison distribution) as well as trends in mortality (using a binomial distribution) adjusted for age, sex and comorbidity.
Results
Across 12,446 individual patients, there were a total of 12,667 hospitalisations (mean age 68±17 years, 55% females) with infective endocarditis using a 5-year look back period. The estimated crude rate of hospitalisation increased from 7.38 per 100,000 (95% CI 6.58 to 8.28) in 1990 to 15.09 per 100,000 (95% CI 13.90 to 16.39) in 2014 (p<0.001). Over the period of the study, 31% (3,877/12,667) of people admitted to hospital with infective endocarditis died within one year of admission. Case fatality fell markedly in both men and women from 1990 to 2014 (Figure). Microbiology was status was available for 34% of all hospitalisations with staphylococcus cultures associated with worse outcomes.
Conclusions
Despite the crude incidence of infective endocarditis doubling over the last 25 years and case fatality remaining high, the risk of death has markedly fallen over the last two decades. Staphylococcus cultures remain an independent marker of poor prognosis in this cohort.

Abstract
Arthrogryposis multiplex congenita, or AMC, is a clinical sign defined as congenital contractures of at least two joint levels. These joint contractures are always secondary to diminished fetal movement which can have numerous causes that affect any part of the anatomical structures implicated in movement: the central nervous system, the anterior horn cell, the nerve, the neuromuscular junction, the muscle, or the joint itself. Make a precise diagnosis of the cause in a patient with multiple joint contractures is therefore challenging. The aim of this article is to summarize the use and diagnostic value of common examinations and analyses performed postnatally in patients affected by AMC from a literature review. We also compare this data with results from our clinical practice. Even though it is difficult to give precise guidelines today, it appears that genetic studies, such as whole exome or genome analysis in all patients and chromosomal microarray analysis in patients with intellectual disability and AMC should be preferred as first tier investigations over EMG and muscle biopsy.

Abstract
Background Age is a significant risk factor for recurrent urinary tract (rUTI) infections, but the clinical picture is often confused in older patients who also present with asymptomatic bacteriuria (ASB). Yet, how bacteriuria establishes in such patients and the factors underpinning and/or driving symptomatic UTI episodes are still not understood. To explore this further a pilot study was completed in which 30 male and female community based older patients (mean age 75y) presenting clinically with ASB / rUTIs and 15 control volunteers (72y) were recruited and monitored for up to 6 months. During this period symptomatic UTI episodes were recorded and urines collected for urinary cytokine and uropathogenic Escherichia coli (UPEC) analyses. Results Eighty-six per cent of patients carried E. coli (102 ≥ 105 CFU/ml urine) at some point throughout the study and molecular typing identified 26 different E. coli strains in total. Analyses of urine samples for ten different cytokines identified substantial patient variability. However, when examined longitudinally the pro-inflammatory markers, IL-1 and IL-8, and the anti-inflammatory markers, IL-5 and IL-10, were significantly different in the patient urines compared to those of the controls (P < 0.0001). Furthermore, analysing the cytokine data of the rUTI susceptible cohort in relation to E. coli carriage, showed the mean IL-10 concentration to be significantly elevated (P = 0.04), in patients displaying E. coli numbers ≥105 CFU/ml. Conclusions These pilot study data suggest that bacteriuria, characteristic of older rUTI patients, is associated with an immune homeostasis in the urinary tract involving the synthesis and activities of the pro and anti-inflammatory cytokines IL-1, IL-5, IL-8 and IL-10. Data also suggests a role for IL-10 in regulating bacterial persistence.
