Abstract
This study aims to comprehensively characterize 576 inhibitors targeting Spleen Tyrosine Kinase (SYK), a non-receptor tyrosine kinase primarily found in haematopoietic cells, with significant relevance to B-cell receptor function. The objective is to gain insights into the structural requirements essential for potent activity, with implications for various therapeutic applications. Through chemoinformatic analyses, we focus on exploring the chemical space, scaffold diversity, and structure-activity relationships (SAR). By leveraging ECFP4 and MACCS fingerprints, we elucidate the relationship between chemical compounds and visualize the network using RDKit and NetworkX platforms. Additionally, compound clustering and visualization of the associated chemical space aid in understanding overall diversity. The outcomes include identifying consensus diversity patterns to assess global chemical space diversity. Furthermore, incorporating pairwise activity differences enhances the activity landscape visualization, revealing heterogeneous SAR patterns. The dataset analysed in this work has three activity cliff generators, CHEMBL3415598, CHEMBL4780257, and CHEMBL3265037, compounds with high affinity to SYK are very similar to compounds analogues with reasonable potency differences. Overall, this study provides a critical analysis of SYK inhibitors, uncovering potential scaffolds and chemical moieties crucial for their activity, thereby advancing the understanding of their therapeutic potential.

Abstract
OBJECTIVES To elucidate the expression levels and prognostic value of the Lipoyltransferase 2 (LIPT2) gene in a pan-cancer view. METHODOLOGY Our study comprehensively investigated the role of LIPT2 in pan-cancer, combining bioinformatics analyses with experimental validations. RESULTS Analysis of LIPT2 mRNA expression across various cancers revealed a significant up-regulation in 18 tumor types and down-regulation in 8 types, indicating its diverse involvement. Prognostic assessment demonstrated a correlation between elevated LIPT2 expression and poorer outcomes in Overall Survival (OS) and Disease-Free Survival (DFS), particularly in Glioblastoma Multiforme (GBM), Liver Hepatocellular Carcinoma (LIHC), and Pheochromocytoma and Paraganglioma (PCPG). Protein expression analysis in GBM, LIHC, and PCPG affirmed a consistent increase in LIPT2 levels compared to normal tissues. Examining the methylation status in GBM, LIHC, and PCPG, we found reduced promoter methylation levels in tumor samples, suggesting a potential influence on LIPT2 function. Genetic mutation analysis using cBioPortal indicated a low mutation frequency (< 2%) in LIPT2 across GBM, LIHC, and PCPG. Immune correlation analysis unveiled a positive association between LIPT2 expression and infiltration levels of immune cells in GBM, LIHC, and PCPG. Single-cell analysis illustrated LIPT2's positive correlation with functional states, including angiogenesis and inflammation. Enrichment analysis identified LIPT2-associated processes and pathways, providing insights into its potential molecular mechanisms. Drug sensitivity analysis demonstrated that elevated LIPT2 expression conferred resistance to multiple compounds, while lower expression increased sensitivity. Finally, RT-qPCR validation in HCC cell lines confirmed the heightened expression of LIPT2 compared to a control cell line, reinforcing the bioinformatics findings. CONCLUSION Overall, our study highlights LIPT2 as a versatile player in cancer, influencing diverse aspects from molecular processes to clinical outcomes across different cancer types.

Abstract
OBJECTIVES This study aimed to evaluate whether the Families First Coronavirus Response Act (FFCRA) modified the association between pre-existing state paid sick leave (PSL) and weekday workplace mobility between February 15 and July 7, 2020. STUDY DESIGN This was a longitudinal, observational study. METHODS The 50 US states and Washington, D.C., were divided into exposure groups based on the presence or absence of pre-existing state PSL policies. Derived from Google COVID-19 Community Mobility Reports, the outcome was measured as the daily percent change in weekday workplace mobility. Mixed-effects, interrupted time series regression was performed to evaluate weekday workplace mobility after the implementation of the FFCRA on April 1, 2020. RESULTS States with pre-existing PSL policies exhibited a greater drop in mobility following the passage of the FFCRA (β = -8.86, 95% confidence interval: -11.6, -6.10, P < 001). This remained significant after adjusting for state-level health, economic, and sociodemographic indicators (β = -3.13, 95% confidence interval: -5.92, -0.34; P = .039). CONCLUSIONS Pre-existing PSL policies were associated with a significant decline in weekday workplace mobility after the FFCRA, which may have influenced local health outcomes. The presence of pre-existing state policies may differentially influence the impact of federal legislation enacted during emergencies.

Abstract
BackgroundPoor health-related quality of life (HR-QoL) is recognised in patients with established connective tissue diseases (CTDs), however it is not clear how it affects patients with undifferentiated CTD (UCTD) which has traditionally been associated with a mild or more benign profile.ObjectivesTo investigate HR-QoL in patients affected with a variety of CTDs (including UCTD) using the SF-36 questionnaire; and secondly, to review demographic and clinical factors predictive of a poor HR-QoLMethodsThe Lupus Extended Autoimmune Phenotype (LEAP) cohort is a multicentre prospective study of patients with a CTD. Rheumatologist diagnosis was used to classify patients into four groups: systemic lupus erythematosus (SLE), primary Sjögren’s syndrome (pSS), UCTD, and (combined because of low numbers) those with an idiopathic inflammatory myopathy (IIM), systemic sclerosis (SSc) or overlap syndrome. The SF-36 quality of life questionnaire was completed at enrolment and includes eight domains: physical function (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE) and mental health (MH) which range from 0 to 100, with higher scores reflecting better HR-QoL. Physical (PCS) and mental component score (MCS) were calculated for each group, with a score below 50 representing a worse HR-QoL compared to the general UK population. Predictors for poor HR-QoL was chosen a priori, then tested using linear regression adjusted for age, gender and ethnicity. All statistical analysis was performed using STATA v14, with results expressed as beta coefficients with 95% confidence intervals (95%CI).ResultsData were collected from 309 patients (280 [90.6%] women, with a mean [SD] age of 48.9 [12.9] years) from three UK rheumatology centres. The majority of patients were Caucasian (n=235, 76.1%). By rheumatologist diagnosis, 115 (37.2%) had SLE, 56 (18.1%) pSS, 72 (23.3%) UCTD and 66 (21.4%) SSc, IIM or an overlap syndrome. Patients with UCTD, pSS and SSc/IIM spectrum disorders had a shorter median disease duration (3.8, 3.7 and 6.1 years respectively) compared with patients with those with SLE (11.0 years), p<0.001. Previous steroid and immunosuppressant use was highest in patients with SLE and SSc/IIM spectrum disorders (p<0.001). The most affected domains include VT, GH and BP (Figure 1), and the PCS is more impaired compared with the MCS, with similar scores across disease groups. Agnostic of disease group, factors associated with a lower PCS include increasing age (beta -0.15 [95%CI -0.26, -0.06], p=0.008), prednisolone use (-3.1 [-6.05, -0.19], p=0.037), c-reactive protein (-0.09 [-0.62, -0.10], p=0.007), fatigue (-2.00 [-3.79, -0.22], p=0.028), and sicca syndrome (-4.70 [-7.66, -1.74] p=0.002), and these remained significant in a multivariate model.Figure 1.radar diagrams of eight SF-36 domains, and MCS and PCS boxplots.

Abstract
Background and Aims : This study aims to evaluate the implication of peer-assisted learning model adopted in students' clinical skills training from the perspective of tutees and tutors at the end of a peer-tutored clinical skills program and peer tutors themselves. Subjects and Methods This cross-sectional study was conducted in the Faculty of Medicine, Bursa Uludag in between January and March 2018. Following the clinical skills training, a questionnaire designed to assess the views of tutees and peer tutors was filled out on a voluntary basis by 159 tutees and 43 tutors. The statistical analysis of the collected and processed data was analyzed by using IBM SPSS 23.0 statistical program. The statistical significance level was maintained as α = 0.05. Results According to the Likert scale, satisfaction with the tutors and the educational environment was high in general. The 2nd term tutees provided more negative feedback compared to other terms. Among all the terms, the most positive answers were provided by the 3rd term students. Although the tutors found themselves fully skilled in communication with colleagues, there were striking differences between the tutors in the 5th and 6th terms of providing a good role model for pre-clinical terms students. Conclusion Considering peer assisted learning (PAL)'s positive responses from this study, the adoption of PAL has been started to be used as a supplementary teaching method for the clinical skills training at the Faculty of Medicine, Bursa Uludag University. PAL is considered a successful education model since it is cost-efficient for undergraduate medical training and improves the professional skills of both teacher and learner students. It can be availed of as an alternative method in medical faculties where especially the number of academic members is insufficient.

Abstract
The patient with diabetes mellitus (DM) and its complication is increasing in our country and all over the world. Fibrinogen is a renowned factor of progressive atherosclerotic lesions and a predictor of cardiovascular events. Level of fibrinogen is increases in patients with diabetes mellitus (DM) may accelerate thromboembolic risk for cardiovascular disease (CVD). This study was carried out to assess plasma fibrinogen level in subjects with type 2 diabetes mellitus. It was a cross sectional analytic study and conducted in the Department of Physiology, Dhaka Medical College, Dhaka, Bangladesh from July 2013 to June 2014. A total number of 200 adult male subjects were selected with age ranging from 40-60 years. Among them, 100 subjects with type 2 diabetes mellitus were included in the study group (Group B) and 100 healthy subjects with same age range were considered as controls (Group A) for comparison. The subjects were selected from BIRDEM hospital Dhaka and personal contact from different areas of Dhaka city on the basis of exclusion and inclusion criteria. The study parameter was plasma fibrinogen level, and was measured in the Department of Microbiology and Immunology of BIRDEM hospital, Dhaka, Bangladesh. The data were collected and recorded in pre-designed structured questionnaire by the researcher herself. For statistical analyses unpaired Student's 't' test and Pearson's correlation coefficient (r) test were performed as applicable using SPSS for windows version 19.0. In this study plasma fibrinogen level was significantly (p<0.001) higher in the study group than that of control group. From this study, it may be concluded that estimation of plasma fibrinogen level might be beneficial for prediction of future cardiovascular risk in adult diabetic male.

Abstract
Abstract
Aim
Which theories, concepts and frameworks have been evidenced for surgical innovation in leadership in the United Kingdom, European Union, and the United States of America?
Method
Systematic scoping synthesis of literature will be employed where appropriate theories, concepts and frameworks will be identified. Drawing upon broader literature on leadership innovation in surgery further examples will be utilised within surgery. s and full- text articles will be used and reviewed for relevance to the research question against an inclusion and exclusion criteria.
Results
The theories of innovative leadership in surgery are broad and non-specific. It demands a professionalism, competence, teamwork, and motivation. Upon comparison of the three country/region profiles there are strong similarities but present differences. It is paramount to understand and underpin these theories in order to foster the future of innovation in surgery. Surgery is fast evolving and developments in leadership must evolve with it. Within innovation, leadership skills must be harnessed including experience and observation. It is through an interprofessional team that surgeons must collaborate in order to provide optimum results and to permit the profession to evolve.
Conclusions
Innovation and surgery are symbiotic, and the next generation of surgical leaders must foster an environment where this is possible to cultivate. Programmes across these country profiles must ensure innovative leadership is present through good mentorship, coaching, team empowerment and feedback. Future directions must be put in place in post -graduate surgical training programmes to ensure that patient care is optimised as the primary objective.

Abstract
Abstract
Aim
Oesophageal and gastric cancers are the eighth and fifth most prevalent cancers with a high degree of morbidity and mortality. Oesophagogastric resections are associated with a high degree of complications postoperatively. Complications following resection are associated with poorer hospital recovery, recurrence of cancer, readmission to hospital and increased mortality. A study was carried out to examine if there was an association between post-operative bloods and the development of complications.
Method
Data was collected from theatre logbooks, Integrated Clinical Environment (ICE) and clinical portal. Patients undergoing oesophagogastric resection for gastric and oesophageal cancer between October 2010 and November 2014 were included. Complications were organised using the Clavien Dindo classification. Data was analysed using the Student’ T test and Chi-Squared test. A P-value of 0.05 was classed as being statiscally significant.
Results
94 patients met the inclusion criteria for this study. 55 patients (58.5%) underwent Oesophagectomy, 18 (19.1%) total gastrectomy and 21 (22.3%) partial gastrectomy. A significant association was seen between development of complications and higher Day 5 White Cell count (WCC) (p = 0.048), lower Day 2–5 Albumin (Day 2 Albumin p = 0.038) and higher Day 2–5 C Reactive Protein (CRP) (Day 2 CRP p<0.001).
Conclusions
This study suggests Albumin, CRP and WCC may be used to predict postoperative complications in patients undergoing oesophagogastric resections for malignancy. Changes in the blood parameters present as early as day 2 postoperatively and can highlight patients who require closer monitoring, allowing earlier re-intervention if required.

Abstract
OBJECTIVE Due to the continued spread of COVID-19 and the emergence of novel mutated viral variants, families all over the world are experiencing wide-ranging stressors that threaten not only their financial well-being but also their physical and mental health. The present study assessed the association between excessive electronic media exposure of pandemic-related news and mental health of the residents of Ha'il Province, Saudi Arabia. The present study also assessed the prevalence of perceived stress, fear of COVID-19, anxiety, depression, and loneliness due to COVID-19-related restrictions in the same population. MATERIALS AND METHODS A total of 490 residents of Ha'il Province participated in a cross-sectional online survey during a two-month period (March to April 2021). A validated 38-item self-report survey was used to collect the data. RESULTS Significant associations were reported between excessive electronic media exposure and the prevalence of perceived stress (χ2=140.56; p<.001), generalized anxiety (χ2=74.55; p<.001), depression (χ2=71.58; p<.001), COVID-19-related fear (χ2=24.54; p<.001), and loneliness (χ2=11.46; p<.001). It was also found that participants without depressive symptoms were 0.28 times less likely to have been exposed to excessive electronic media exposure (AOR: 0.28; C.I. 0.16-0.48; p<.001). Similarly, participants with no stress/mild stress were 0.32 times less likely to have been exposed to excessive electronic media exposure (AOR: 0.32; C.I. 0.19-0.52; p<.001). CONCLUSIONS The findings of the present study suggest an urgent need for educational resilience programs (online and in-person) for susceptible individuals (females, unemployed, urban residents, etc.). Such programs would help them to develop skills to cope with the psychological impact of the COVID-19 pandemic.

Abstract
Introduction
To reduce the risk of regurgitation and aspiration of gastric contents, patients are to fast before anaesthesia. However, prolonged periods of fasting have been found to be unnecessary and potentially harmful. Our aim was to compare pre-operative fasting times in trauma patients against the AAGBI (Association of Anaesthetists of Great Britain and Ireland) guidelines and highlight areas for improvement. The AAGBI recommends minimum fasting periods of:
Method
50 patients were audited in each cycle. Data were collected prospectively using questionnaires in the initial audit and by interviewing patients in the re-audit. Patients in ITU and those with dementia were excluded. Questions included fasting instructions given, time of the last meal and drink (including kind of drink), IV fluids administration. Anaesthetic notes were checked for time of induction of anaesthesia.
Results
Average time fasted for food was 17.09 hours and 9.32 hours for water. In the re-audit, average time fasted was 16.43 hours for food and 5.27 hours for water. All the patients received information as to when they could eat or drink until. None of them was told ‘midnight’.
Conclusions
Although there was an improvement, this was still beyond the guidelines. The results highlighted the importance of regularly reviewing the fasting status throughout the day in order to achieve the standard.

Abstract
Background Surgical intervention for neck of femur fractures continues to be prioritised during the Covid-19 pandemic. However, there remains a lack of clarity for clinicians during the consent process. This study quantifies additional perioperative risks for Covid-19 positive patients undergoing neck of femur fracture surgery and establishes an evidence-based framework for facilitating informed consent during the Covid-19 pandemic. Method 259 patients undergoing neck of femur fracture surgery in four hospitals at the epicentre of the United Kingdom’s first wave of Covid-19 were recruited. 51 patients were positive for Covid-19. Predefined outcomes were recorded in a 30-day postoperative period. Results Odds of intensive care admission were 4.64 times higher (95% CI 1.59-13.50, p = 0.005) and odds of 30-day mortality were 3 times higher (95% CI 1.22-7.40, p = 0.02) in Covid-19 positive patients. 74.5% of Covid-19 positive patients suffered post-operative complications. 35.3% of Covid-19 positive patients developed lower respiratory tract infection with 13.7% progressing to acute respiratory distress syndrome. 9.8% of Covid-19 positive patients experienced symptomatic thromboembolic events with a 3.9% incidence of pulmonary emboli. Conclusions The implications of Covid-19 on the informed consent process for neck of femur fracture surgery are profound. Covid-19 positive patients should be consented for increased risk of postoperative complications (including lower respiratory tract infection, acute respiratory distress syndrome and thromboembolic events), longer inpatient stay, increased frequency of intensive care admission and higher risk of mortality.

Abstract
OBJECTIVE: The current study reviewed Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) variants for their effects on infection, transmission and neutralization by vaccine-induced antibodies. MATERIALS AND METHODS: The research articles for the current study were searched over PubMed, Google Scholar, EMBASE and Web of Science online databases. The keywords used were: (("SARS-CoV-2" OR "COVID-19") AND ("mutation" OR "variant") AND ("death" OR "hospitalization" OR "infection" OR "transmission") AND ("antibody" OR "neutralize" OR "vaccine")). A total of 333 research articles were retrieved through online-database search. These articles were further scrutinized for their relevancy. Additionally, searches were performed to find the latest relevant information over Google search engine and relevant news browsers. Finally, around 35 germane articles were considered for scripting the current report. RESULTS: The mutations have changed amino acids at key positions in spike protein viz. S477N, E484K, Q677H, E484Q, L452R, K417T, K417N and N501Y. These mutations are relevant for different characteristics and are present in newly evolved strains of SARS-CoV-2 like E484K in B.1.526, B.1.525, P.2, B.1.1.7, P.1 and B.1.351. Mutations have increased the immune escape potential leading to 3.5-6.5-folds decrease in neutralization of antibodies (Pfizer and Moderna vaccines). The variant, B.1.617 circulating in India and many other countries (double variant) having E484Q and L452R mutations, has raised the infection rate and decreased the neutralization capacity of the vaccine-induced antibodies. Deadly K417N+E484K+N501Y triplet mutations found in B.1.351 and P.1 have increased the transmission ability of these strains by 50% leading to greater COVID-19 hospitalization, ICU admissions and deaths. CONCLUSIONS: The new SARS-CoV-2 variants have compromised the neutralization potential of the currently used vaccines, but still, they have considerable efficacy to reduce infection and mortality.

Abstract
BACKGROUND Photodiagnostic investigations are essential for the accurate diagnosis of abnormal cutaneous photosensitivity and provide important information for the management of patients with photodermatoses (cutaneous photosensitivity disorders). Although photodiagnosis has been undertaken since the early 1970s, specialist services in the United Kingdom (UK) and Republic of Ireland are limited and there is no formal guidance on diagnostic approach. Indeed, there is a limited literature in this area of methodology and diagnostic practice. OBJECTIVES The primary objective was to undertake a British Photodermatology Group Workshop to review the role and activities of specialist centres in the UK and Republic of Ireland in order to ascertain whether there were consensus practices. Secondary objectives were to identify key priorities for service, training and research. METHODS An initial detailed survey review of current activities was undertaken prior to the Workshop and data from this survey were used to inform discussion at the Workshop, which was attended by key photodermatology experts from the UK and Republic of Ireland. RESULTS/CONCLUSIONS We have undertaken a detailed review of current Photodiagnostic Services in the UK and Republic of Ireland and report on our findings from the 12 centres and we have identified key areas of consensus practice. This is an important step in the process of standardising and optimising procedures and protocols and defining minimum clinical standards for photodiagnostic investigations, which are of such diagnostic importance in Dermatology.

Abstract
OBJECTIVE Nitric Oxide (NO) is produced by NO synthases (NOS) and is a key signaling molecule that regulates tumorigenesis, both aiding and alleviating it. Elevated NO levels are cytotoxic to cancer cells, making NOS an important target for cancer treatment. In the present study, the modulatory effects of the phytochemicals, quercetin, sulforaphane, genistein, and epigallocatechin-3-gallate on NO pathway and apoptosis were shown in HeLa cervical cancer cells. MATERIALS AND METHODS Fluorescent microscopy and flow cytometry were used to assess apoptosis. A Griess assay was used to quantitatively measure NO, quantitative PCR array was used to assess the expression levels of genes involved in the NO signaling pathway, and immunocytochemistry was used to determine NOS protein expression. The functional association among the modulated genes was evaluated using network biology analysis, gene set enrichment, and KEGG pathway analysis. RESULTS Treatment with the phytochemicals elevated NO levels in HeLa cells and modulated various genes involved in nitric oxide biosynthesis, superoxide metabolism, and oxidative stress, including NOS1, NOS2, NOS3, ALOX12, and SOD2, with a concomitant increase in NOS2 and NOS3 protein expression levels; also, the phytochemicals were found to induce apoptosis. CONCLUSIONS These results suggest that the phytochemical-induced cell death is partially attributed to the activation of the NO pathway and upregulation of pro-oxidant ROS generators. Further experimental studies are required to explore this mechanistic association of NO signaling pathway activation and induction of apoptosis in other types of cancer.

Abstract
Abstract
Introduction
Surgical departments across the UK are having to mitigate service demands, budget constraints and changes to work patterns with their statutory duty to provide high-quality training and education. Securing consultant-led teaching has also become increasingly difficult leading to the rise of near-peer teaching. We evaluate the long-term effectiveness of near-peer surgical teaching for junior doctors.
Method
We developed a rolling 12-week trainee-led didactic surgical education programme for Foundation doctors and Core Surgical Trainees. Junior doctors delivered teaching to peers with registrar input; session and supervision feedback was recorded using 5-point scales and free-text responses.
Results
42 junior doctors responded to our end-of-programme feedback surveys covering December 2018 to April 2020. The overall programme (8.83±1.08/10), relevance (4.62±0.58/5), presentation quality (4.60±0.50/5) and supervisor knowledge (4.81±0.40/5) were rated highly by respondents. Attendees also reported significant improvements in subject knowledge (3.72±0.92/5 to 4.50±0.56/5, P < 0.0001), clinical confidence, presentation and teaching skills.
Conclusions
Our near-peer teaching programme addressed the educational needs of junior doctors and developed their presentation and organisational skills. Supervision and input from registrars facilitated discussion and reinforced key concepts. The success of this programme highlights the role that trainees can play in designing, developing, and leading an effective surgical teaching programme.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) uses Angiotensin- converting enzyme 2 (ACE2) receptors to infect host cells which may lead to coronavirus disease (COVID-19). Given the presence of ACE2 receptors in the brain and the critical role of the renin-angiotensin system (RAS) in brain functions, special attention to brain microcirculation and neuronal inflammation is warranted during COVID-19 treatment. Neurological complications reported among COVID-19 patients range from mild dizziness, headache, hypogeusia, hyposmia to severe like encephalopathy, stroke, Guillain-Barre Syndrome (GBS), CNS demyelination, infarcts, microhemorrhages and nerve root enhancement. The pathophysiology of these complications is likely via direct viral infection of the CNS and PNS tissue or through indirect effects including post- viral autoimmune response, neurological consequences of sepsis, hyperpyrexia, hypoxia and hypercoagulability among critically ill COVID-19 patients. Further, decreased deformability of red blood cells (RBC) may be contributing to inflammatory conditions and hypoxia in COVID-19 patients. Haptoglobin, hemopexin, heme oxygenase-1 and acetaminophen may be used to maintain the integrity of the RBC membrane.

Abstract
The patient with diabetes mellitus and its complication is increasing in our country and all over the world. Altered platelet morphology and function have been reported in patient with DM. Mean platelet volume has been suggested as a newly emerging and independent risk marker for atherothrombosis and cardiovascular disease. The present study was carried out to assess the mean platelet volume in subjects with type 2 diabetes mellitus. The present study was a cross sectional analytic study and conducted in the Department of Physiology, Dhaka Medical College, Dhaka, Bangladesh from July 2013 to June 2014. A total number of 200 adult male subjects were selected with age ranging from 40 to 60 years. Among them, 100 subjects with type 2 diabetes mellitus were included in the case (Group B) and 100 healthy subjects with same age range were considered as control (Group A) for comparison. The subjects were selected from BIRDEM hospital Dhaka and personal contact from different areas of Dhaka city on the basis of exclusion and inclusion criteria. The study parameter was mean platelet volume and was measured in the Department of Hematology of BIRDEM hospital, Dhaka. The data were collected and recorded in pre-designed structured questionnaire by the researcher herself. For statistical analyses unpaired Student's 't' test was performed as applicable using SPSS for windows version 19. In this study, mean platelet volume was significantly (p<0.001) higher in the case group than that of control group. Therefore, estimation of mean platelet volume might be beneficial for prediction of future cardiovascular risk in adult diabetic male.

Abstract
Background:Patients with rheumatological foot disease are an overlooked population, and it was noted locally that these patients received a fragmented service; attending multiple appointments for the management of one clinical issue. This led to delays in treatment; significant inter-departmental correspondence and variations in the peri-operative management of disease modifying anti-rheumatic drug (DMARD) and biologic therapies. To remedy this a foot multidisciplinary (MDT) clinic was established, including input from rheumatology, orthopaedic surgery, specialist rheumatology podiatry and physiotherapy. The outcomes from the foot MDT clinic have been analysed in this service evaluation project.Objectives:To evaluate the outcomes of the multidisciplinary foot MDT clinic, with particular reference to concordance to the British Rheumatology Society (BSR) guidelines on peri-operative medicine guidelines.Methods:Data was collected retrospectively across all clinics from January 2017 to February 2019. Clinic letters were obtained, and data was collected using a standardised data collection sheet. Data was collected on patient demographics, rheumatological diagnoses, treatment outcomes from the foot MDT, appropriateness of peri-operative plan and post-operative complications. No data was available on these outcomes prior to the advent of the foot MDT clinic.Results:Data from 12 clinics was analysed (n=40). Patients had a median age of 66 years (IQR 27.5 years); 65% of patients were female and 35% of patients were male. The commonest rheumatological foot disease seen was rheumatoid arthritis (67%), followed by psoriatic arthritis (15%). All patients were treated with biologic or non-biologic DMARDs. Treatment outcomes were as follows: 27.5% were offered surgical treatment; 10% were offered intra-articular (IA) injections under ultrasound guidance; 10% were offered IA injections under general anaesthetic; 25% underwent specialist rheumatology podiatry, and the remaining 30% elected for a conservative approach after careful consideration of treatment options. Of those who were offered surgical treatment, 72% of patients were provided with a peri-operative plan which accorded with British Rheumatology Society (BSR) guidelines. Of those whom underwent surgery, one patient’s surgical treatment was complicated by a post-operative infection; however, the peri-operative DMARD/biologic plan was not felt to be contributing factor.Conclusion:The foot MDT clinic provides a comprehensive review of rheumatological foot conditions, with readily available access to a full range of treatment options. Co-location of all relevant professionals allows for real-time interdepartmental communication; shared decision making between clinicians and patients; avoids multiple appointments; reduces uncertainty with peri-operative planning as well as providing a cost-effective and efficacious service. Discrepancies in the peri-operative plan for medicines arose when the treating orthopaedic surgeon was not present in clinic. In these cases, the plan for surgical treatment was made outside of this clinic, without input from the treating rheumatologist. To improve concordance with BSR peri-operative medicine guidelines, it is recommended that all treatment decisions are made during the clinic, allowing input from all relevant partners. Informal feedback from patients commended the foot MDT, this shall be formalised through further qualitative data.Disclosure of Interests:None declared

Abstract
Background:The EULAR-ACR 2019 (EULAR19) classification criteria for systemic lupus erythematosus (SLE) were developed to improve the sensitivity and specificity of previous criteria. Notably, both the EULAR19 and existing SLICC-SLE 2012 (SLICC12) criteria can classify patients as having SLE by the presence of immunology and haematological abnormalities in the absence of any signs or symptoms.Objectives:To validate the EULAR19 criteria, with comparison to existing criteria, in a large cohort of patients with an established systemic autoimmune rheumatic disease (SARD).Methods:We recruited 227 adult patients who were ANA positive with ≥1 clinical feature suggestive of a SARD, from three hospitals in the North West of England. Clinician diagnosis was used as gold standard; we then applied the EULAR19, SLICC12 and the ACR-SLE 1997 (ACR97) criteria.Results:Of the 227 patients recruited, by clinician diagnosis, 89 patients (36%) had SLE, 43 (17%) primary Sjögren’s (pSS), 62 (25%) undifferentiated CTD (UCTD), 25 (10%) systemic sclerosis (SSc) and 8 (3%) an inflammatory myositis. The characteristics of these patients and the breakdown of the EULAR19 criteria are outlined in figure 1.Figure 1.Baseline characteristics and classification criteria compared across five SARD diagnoses.The sensitivity and specificity of the EULAR19 is similar to ACR97 (sensitivity 84% (95% CI 75-91%) vs. 87% (95% CI 78-93%) and specificity 78% (95% CI 70-84%) vs. 76% (95% CI 68-83%) respectively). The SLICC12 criteria by contrast are more sensitive (94% (95% CI 87-98%)) and less specific (61% (95% CI 52-69%)) in this cohort.Figure 2 illustrates patients with a clinician diagnosis of SLE or UCTD who meet each of the classification criteria. Of the 89 patients with a clinician diagnosis of SLE, 39 (44%) patients would have sufficient points to meet EULAR19 criteria on blood test results alone in the absence of clinical symptoms. Four pSS patients and 4 UCTD patients would also meet EULAR19 criteria from positive blood results alone.Figure 2.Venn diagrams illustrating patients with SLE and UCTD who meet the EULAR19, ACR97 and SLICC12 classification criteria. No criteria refers to the patients not meeting any of the three SLE classification criteria.Conclusion:These results suggest that the EULAR19 criteria perform comparably to the ACR97 criteria when applied to an established cohort of SARDs. Similar to SLICC12, it is possible to classify patients as having SLE using the EULAR19 criteria by haematological and other laboratory tests. To what extent haematological abnormalities can be potentially used as the sole ‘clinical criteria’ needs consideration.SLE n=89pSS n=43UCTD n=62SSc n=25Myositis n=8Female N (%)82 (92)42 (98)53 (85)24 (96)8 (100)Age, mean (SD) /years44 (13)52 (12)47 (13)60 (9)53 (7)Disease duration, mean (SD) /years12 (10)6 (5)5 (7)9 (11)3 (3)SLE classification criteriaEULAR SLE 2019, N (%)75 (84)10 (23)20 (32)1 (4)0ACR SLE 1997, N (%)77 (87)9 (21)21 (34)2 (8)1 (13)SLICC SLE 2012, N (%)84 (94)15 (35)33 (53)4 (16)2 (25)EULAR-ACR 2019 criteriaConstitutional, N (%)10 (11)2 (5)1 (2)01 (13)Neuropsychiatric, N (%)3 (3)01 (2)1 (4)0Mucocutaneous, N (%)71 (80)13 (30)27 (44)2 (8)2 (25)Serosal, N (%)13 (15)1 (2)2 (3)00Musculoskeletal, N (%)52 (58)14 (33)22 (35)3 (12)3 (38)Renal, N (%)30 (34)001 (4)0Haematological, N (%)44 (49)12 (28)10 (16)3 (12)0Antiphospholipid antibodies, N (%)43 (48)7 (16)17 (27)4 (16)0Low complement, N (%)48 (54)10 (23)10 (16)3 (12)1 (13)Anti-Sm, N (%)19 (21)2 (5)4 (6)1 (4)0Anti-dsDNA, N (%)50 (56)8 (19)12 (19)01 (13)Disclosure of Interests:Sarah Dyball: None declared, John Reynolds: None declared, Eoghan McCarthy: None declared, Sahena Haque: None declared, Ariane Herrick: None declared, Hector Chinoy: None declared, Ellen Bruce: None declared, Ben Parker Grant/research support from: GSK and Sanofi Genzyme, Consultant of: GSK, AstraZenaca, UCV, Abbvie, Pfizer, BMS, Celltrion, Ian N.
