Abstract
BACKGROUND A serious game called SPARX (Smart, Positive, Active, Realistic, X-factor thoughts), originally developed in New Zealand and incorporating cognitive behavioural therapy (CBT) principles, has been shown to help reduce symptoms of depression and anxiety in adolescents with mild to moderate depression in studies undertaken in Australasia. However, SPARX has never been trialled in the United Kingdom (UK), and there have been issues relating to low engagement when it has been used in a real-world context. AIMS To conduct the first pilot and feasibility randomised controlled trial (RCT) in England to explore the use of SPARX in different settings. The trial will explore whether SPARX supported by an e-coach (assistant psychologists) improves adherence and engagement compared with self-directed (i.e. self-help) use. The trial results will be used to inform the optimal mode of delivery (SPARX supported vs. SPARX self-directed), to calculate an appropriate sample size for a full RCT, and to decide which setting is most suitable. METHODS Following consultation with young people to ensure study suitability/appropriateness, a total of 120 adolescents (11-19 years) will be recruited for this three-arm study. Adolescents recruited for the study across England will be randomised to receive either SPARX with human support (from an e-coach), self-directed SPARX, or a waitlist control group. Assessments will be conducted online at baseline, week 4, and 8-10-week post-randomisation. The assessments will include measures which capture demographic, depression (Patient Health Questionnaire modified for adolescents [PHQ-A]) and anxiety (Revised Child Anxiety and Depression Scale [RCADS]) symptomatology, and health-related quality-of-life data (EQ-5D-Y and proxy version). Analyses will be primarily descriptive. Qualitative interviews will be undertaken with a proportion of the participants and clinical staff as part of a process evaluation, and the qualitative data gathered will be thematically analysed. Finally, feasibility data will be collected on recruitment details, overall study uptake and engagement with SPARX, participant retention, and youth-reported acceptability of the intervention. DISCUSSION The findings will inform the design of a future definitive RCT of SPARX in the UK. If the subsequent definitive RCT demonstrates that SPARX is effective, then an online serious game utilising CBT principles ultimately has the potential to improve the provision of care within the UK's health services if delivered en masse.

Abstract
Abstract The current research work aims to provide knowledge about the diversity of spiders’ fauna and their occurrence throughout the year from District Charsadda Khyber Pakhtunkhwa, Pakistan. Research data were collected from March-2015 to January-2017 from seven different localities of Charsadda District by using the camera, bottle, plastic bags, paraffin films, field book and 70% of ethylene alcohol and 20% of glycerine were used as chemicals. By using special identification keys, spiders were differentiated into families, genera and species. During the study time, a total of 2734 specimens of spiders were collected belonging from 35 genera, 15 families and 44 species were identified. Salticidae was the dominant family according to genera studied plus spiders samples numbers collected with 10 genera and 616 species specimens count. The high occurrence of spiders was studied during July. The result of the current study also shows a reduction of spider’s species in December due to lowering the temperature. The current study shows that Salticidae were the dominant family as capered to other species. The occurrence of spiders species greatly depends on changing the weather condition. The present study also shows great fluctuation in spider’s occurrence with changing of hot climate to colder during the study duration. Moreover, the wet season plays a great role in spiders’ population increase and growth.

Abstract
BACKGROUND Prehospital analgesia is often required after traumatic injury, currently morphine is the strongest parenteral analgesia routinely available for use by paramedics in the United Kingdom (UK) when treating patients with severe pain. This protocol describes a multi-centre, randomised, double blinded trial comparing the clinical and cost-effectiveness of ketamine and morphine for severe pain following acute traumatic injury. METHODS A two arm pragmatic, phase III trial working with two large NHS ambulance services, with an internal pilot. Participants will be randomised in equal numbers to either (1) morphine or (2) ketamine by IV/IO injection. We aim to recruit 446 participants over the age of 16 years old, with a self-reported pain score of 7 or above out of 10. Randomised participants will receive a maximum of 20 mg of morphine, or a maximum of 30 mg of ketamine, to manage their pain. The primary outcome will be the sum of pain intensity difference. Secondary outcomes measure the effectiveness of pain relief and overall patient experience from randomisation to arrival at hospital as well as monitoring the adverse events, resource use and cost-effectiveness outcomes. DISCUSSION The PACKMAN study is the first UK clinical trial addressing the clinical and cost-effectiveness of ketamine and morphine in treating acute severe pain from traumatic injury treated by NHS paramedics. The findings will inform future clinical practice and provide insights into the effectiveness of ketamine as a prehospital analgesia. TRIAL REGISTRATION ISRCTN, ISRCTN14124474.

Abstract
Obesity-associated morbidity is exacerbated by abdominal obesity, which can be measured as the waist-to-hip ratio adjusted for the body mass index (WHRadjBMI). Here we identify genes associated with obesity and WHRadjBMI and characterize allele-sensitive enhancers that are predicted to regulate WHRadjBMI genes in women. We found that several waist-to-hip ratio-associated variants map within primate-specific Alu retrotransposons harboring a DNA motif associated with adipocyte differentiation. This suggests that a genetic component of adipose distribution in humans may involve co-option of retrotransposons as adipose enhancers. We evaluated the role of the strongest female WHRadjBMI-associated gene, SNX10, in adipose biology. We determined that it is required for human adipocyte differentiation and function and participates in diet-induced adipose expansion in female mice, but not males. Our data identify genes and regulatory mechanisms that underlie female-specific adipose distribution and mediate metabolic dysfunction in women.

Abstract
BACKGROUND Research has shown that 20-30% of prisoners meet the diagnostic criteria for attention-deficit hyperactivity disorder (ADHD). Methylphenidate reduces ADHD symptoms, but effects in prisoners are uncertain because of comorbid mental health and substance use disorders. AIMS To estimate the efficacy of an osmotic-release oral system methylphenidate (OROS-methylphenidate) in reducing ADHD symptoms in young adult prisoners with ADHD. METHOD We conducted an 8-week parallel-arm, double-blind, randomised placebo-controlled trial of OROS-methylphenidate versus placebo in male prisoners (aged 16-25 years) meeting the DSM-5 criteria for ADHD. Primary outcome was ADHD symptoms at 8 weeks, using the investigator-rated Connors Adult ADHD Rating Scale (CAARS-O). Thirteen secondary outcomes were measured, including emotional dysregulation, mind wandering, violent attitudes, mental health symptoms, and prison officer and educational staff ratings of behaviour and aggression. RESULTS In the OROS-methylphenidate arm, mean CAARS-O score at 8 weeks was estimated to be reduced by 0.57 points relative to the placebo arm (95% CI -2.41 to 3.56), and non-significant. The responder rate, defined as a 20% reduction in CAARS-O score, was 48.3% for the OROS-methylphenidate arm and 47.9% for the placebo arm. No statistically significant trial arm differences were detected for any of the secondary outcomes. Mean final titrated dose was 53.8 mg in the OROS-methylphenidate arm. CONCLUSIONS ADHD symptoms did not respond to OROS-methylphenidate in young adult prisoners. The findings do not support routine treatment with OROS-methylphenidate in this population. Further research is needed to evaluate effects of higher average dosing and adherence to treatment, multi-modal treatments and preventative interventions in the community.

Abstract
Abstract
Background
Left Main Stem Disease (LMS) is prognostically important coronary artery disease that is managed either with coronary artery bypass surgery (CABG) or percutaneous coronary intervention (PCI). Use of intracoronary imaging (ICI) modalities such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT) have been shown to improve outcomes with PCI revascularization.
The primary objective of this study was to evaluate the impact of ICI on outcomes following LMS PCI.
Methods
Retrospective observation study of 498 (5.1% of all PCI cases) patients who had undergone LMS PCI at our tertiary primary PCI centre hospital over a 11-year period between July 2010-July 2021. Data was collected from electronic medical records. Follow-up was also obtained through linkage with the Office of National Statistics.
Results
The mean age at the time of enrolment was 70.7±11.5 years. Majority of the patients were male 351 (70.5%). 353 (70.9%) of cases had acute coronary syndrome (ACS) presentation while the remainder were elective procedures. Mean follow-up duration was 3.75±3.06 years. Survival calculated by Kaplan-Meier was 70%. 87 patients (17.5%) deceased during first year of enrolment. 344 (69.1%) patients had ICI, with IVUS in 316 (63.5%) and OCT in 28 (5.6%) patients. IVUS comprised 91.9% of ICI procedures. Protected LMS (OR 0.175, 95% CI: 0.037–0.833, P-value=0.029) and the use of left ventricular mechanical support device (OR 0.324, 95% CI: 0.122–0.859, P-value=0.024) were associated with decreased odds of undergoing an ICI.
Patients undergoing ICI had significantly better survival compared to those without ICI (HR: 0.54, P<0.001). Moreover, OCT showed significantly better survival compared with IVUS (HR: 0.181, P=0.017). Use of ICI was associated with better survival in patients who had Rotablation (HR: 0.455, 95% CI: 0.232–0.892, P=0.022), ACS (HR: 0.523, 95% CI: 0.383–0.714, P<0.001) or comorbidities of diabetes and stroke (HR: 0.551, 95% CI: 0.337–0.807, P=0.002).
Conclusion
ICI in LMS PCI has a significant survival benefit in our dataset. This is especially the case in patients presenting with ACS, those with comorbidities of Diabetes mellitus and stroke and those undergoing rotablation.

Abstract
Abstract
Background
Left Main Stem Disease (LMS) has historically been treated with coronary artery bypass surgery (CABG). However, not all patents with LMS are candidates for CABG due to co-morbidities. There is limited long-term follow-up of patients undergoing PCI in the real world. The primary objective of this study was to investigate the long-term mortality following LMS PCI.
Methods
We conducted a retrospective study of patients who had undergone PCI for LMS disease at our hospital over a 11-year period between July 2010-July 2021. Data was collected from electronic medical records and analyzed using Kaplain-Meier survival analysis. Follow-up was obtained through linkage with the Office of National Statistics.
Results
498 patients underwent LMS PCI (5.1% of the total PCI cases). The overall survival rate was 70%. Median survival following PCI was 1,196 days (IQR = 1,796). The mean age of the patients was 70.7 years; 70.5% were males. 70.9% of patients underwent PCI for Acute Coronary Syndrome (ACS), and 15.3% had STEMI. 33.7% of patients had a history of diabetes, 8% had stroke, 8.2% had COPD, and 8.8% had PVD. 51 patients went into cardiogenic shock, and 25 died prior to discharge.
Survival of the ACS group was significantly lower than the stable group (67% vs 77%, p<0.01); the STEMI group did not significantly differ from rest of the ACS group (62% vs 66%, p=0.87). Survival in those <60 years of age was significantly higher than in those >60 years (80% vs 68%; p<0.01). The presence of one or more co-morbidities was associated with higher survival compared to zero co-morbidities (74% vs 65%, p<0.01). Patients with a history of diabetes had a significantly lower survival rate than those without diabetes (63% vs 73%, p<0.01). Patients with an LV ejection fraction ≤35% had a significantly lower survival than those with an ejection fraction >35% (22% vs 29%, p<0.01); only 259 patients had data on LV function. Patients who developed cardiogenic shock had a significantly lower survival rate than those who did not develop shock (38% vs 70%; p<0.01). When these patients were excluded from the data set, the overall survival rate increased from 70% to 74%. Lastly, a multinomial analysis showed that the only independent predictors of mortality were age (p<0.01) and cardiogenic shock (p<0.01).
Conclusion
Our results show that the real world 10-year mortality rate following LMS PCI is influenced by multiple factors including age, shock, and LV function. The high mortality rate was potentially due to the significant number of acute cases (70.1%) in non-operable patients. While factors such as age and past medical history are considered in the decision-making process regarding CABG vs PCI, we saw that specific subgroups within these factors may have decreased the effectiveness of PCI as a treatment for LMS disease, suggesting that deeper analysis into these risk factors is required when deciding between CABG and PCI for LMS disease management.

Abstract
AIMS This article seeks to make the case for a new approach to understanding and nurturing resilience as a foundation for effective place-based co-produced local action on social and health inequalities. METHODS A narrative review of literature on community resilience from a public health perspective was conducted and a new concept of neighbourhood system resilience was developed. This then shaped the development of a practical programme of action research implemented in nine socio-economically disadvantaged neighbourhoods in North West England between 2014 and 2019. This Neighbourhood Resilience Programme (NRP) was evaluated using a mixed-method design comprising: (1) a longitudinal household survey, conducted in each of the Neighbourhoods For Learning (NFLs) and in nine comparator areas in two waves (2015/2016 and 2018/2019) and completed in each phase by approximately 3000 households; (2) reflexive journals kept by the academic team; and (3) semi-structured interviews on perceptions about the impacts of the programme with 41 participants in 2019. RESULTS A difference-in-difference analysis of household survey data showed a statistically significant increase of 7.5% (95% confidence interval (CI), 1.6 to 13.5) in the percentage of residents reporting that they felt able to influence local decision-making in the NFLs relative to the residents in comparator areas, but no effect attributable to the NRP in other evaluative measures. The analysis of participant interviews identified beneficial impacts of the NRP in five resilience domains: social connectivity, cultural coherence, local decision-making, economic activity, and the local environment. CONCLUSION Our findings support the need for a shift away from interventions that seek solely to enhance the resilience of lay communities to interventions that recognise resilience as a whole systems phenomenon. Systemic approaches to resilience can provide the underpinning foundation for effective co-produced local action on social and health inequalities, but they require intensive relational work by all participating system players.

The increasing rate of cardiovascular disease (CVD) contributes to a worsening morbidity in the general population and a socioeconomic burden on the healthcare system. Newly approved therapies present unforeseen side effects and occasionally entail adverse cardiovascular responses in patients - this issue significantly stalls efficacious pharmacological development. Indeed, modern cardiovascular treatments do not account for the variability of individual patient reactions, due to a lack of a representative in vitro cardiac model. While the use of induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) has gained traction as a superior model for drug screening when compared to cardiac biopsies and immortalized cell lines, cardiovascular patient-specific differences remain poorly understood and understudied.
We hypothesized that 1) cardiomyopathic patient-derived iPSC-CMs have differing baselines of beating rate, contractility, viability, metabolic activity and protein expression, when compared to healthy controls, and that 2) cell lines have patient-specific responses to hypoxia-induced injury. As such, the purpose of this preliminary study was two-fold: 1) to perform a characterization of patient iPSC-CM function, and 2) to study patient-specific cellular responses to hypoxia.
First, we generated iPSC-CMs from the peripheral blood of donors (n=6 patients with cardiomyopathies, n=2 healthy donors). We then confirmed the expression of prominent cardiac markers connexin 43 (CXN43), sarcoendoplasmic reticulum Ca2+ ATPase (SERCA2a), GATA4 and cardiac Troponin T, as well as a lack of pluripotency markers Octamer-binding transcription factor 4 (OCT4), Nanog, Stage-specific embryonic antigen-4 (SSEA-4) and TRA-1-60 in the iPSC-CM lines, via immunocytochemistry. Preliminary assessment of iPSC-CMs (days 1-30 post-differentiation) revealed significant baseline differences in beating rate (p<0.01) and contractility amplitude (p<0.01) between iPSC-CMs derived from cardiomyopathic patients and healthy donors.
We then subjected iPSC-CM lines to hypoxic conditions (24 hours), to mimic ischaemic injury. Diseased patient-derived lines had significantly decreased viability and metabolic activity when compared to the controls, under normoxic (p<0.01) and hypoxic conditions (p<0.001). Immunoblotting revealed differential expression of cardiac markers and factors implicated in cardiac function, cardioprotection and pathology. Taken together, these results suggest that the detected differences at the cellular level after hypoxia-induced injury might be translatable to the inter-individual variability currently observed in the CVD patient population. The data gathered will prove to be instrumental in future studies of iPSC-CM responses to treatment. With this preliminary study, we hope to shift the focus towards these patient-specific differences at the cellular level, in the search for tailored therapies and a higher standard of care for CVD patients.

Abstract
Abstract
Aim
Treatment of iron deficiency anaemia in patients undergoing colon cancer resection improves outcome defined by length of stay, recurrence, and requirement for blood transfusions.
Method
Retrospective analysis of patients with anaemia and colonic cancer between January 2018 - August 2019. Anaemia categorised as – Iron Deficiency Anaemia and non- Iron Deficiency anaemia. IDA was defined as hypochromic microcytic anaemia. Patient demographics, tumour location, pre- and post-operative haemoglobin, length of stay, recurrence and requirement for blood transfusions were collected plus treatment for anaemia. Comparisons made between IDA and non-IDA groups in relation to treatment for anaemia with iron (oral/IV). Non-parametric statistical tests used (median, 2-way ANOVA, Kruskal-Wallis) with significance at P <0.05.
Results
150 patients with colonic cancer identified: 77 in IDA group, 46 treated (42 oral, 4 iv iron). 11 in non- IDA group, 8 treated (oral iron).
IDA oral and IV treatment versus non-IDA:
Median age 74, 80 and 78 years (P = 0.814),
Pre- and post op Hb IDA vs non-IDA: 107, 97; 109, 101 (P 0.007 significant),
Requirement for blood transfusion (units) 0.77, 0.50;0.90 (P 0.596)
Length of Stay (days) 6, 5; 7 (P 0.113),
Tumour location: mean of right colon and transverse colon 24.33, 3.667 (P >0.1), and
Recurrence P >0.1.
Conclusions
In our series, iron treatment does not influence recurrence, length of stay, requirement for blood transfusions. Tumour location is not significantly different between IDA and non-IDA group. Patients treated with oral iron therapy are seen to have a larger drop in haemoglobin post operatively than the other groups.

Abstract
Current methods for tuberculosis treatment monitoring are suboptimal. We evaluated plasma matrix metalloproteinase (MMP) and procollagen III N-terminal propeptide concentrations before and during tuberculosis treatment as biomarkers. Plasma MMP-1, MMP-8, and MMP-10 concentrations significantly decreased during treatment. Plasma MMP-8 was increased in sputum Mycobacterium tuberculosis culture–positive relative to culture-negative participants, before (median, 4993 pg/mL [interquartile range, 2542–9188] vs 698 [218–4060] pg/mL, respectively; P = .004) and after (3650 [1214–3888] vs 720 [551–1321] pg/mL; P = .008) 6 months of tuberculosis treatment. Consequently, plasma MMP-8 is a potential biomarker to enhance tuberculosis treatment monitoring and screen for possible culture positivity.

Abstract
Abstract
Whilst a considerable amount of social prescribing activity is taking place across the North West of England, little is known about how different models are being implemented, how data is being collected to support evidence of impact and outcomes, and how these models could be positively or negatively influencing health inequalities. Our study aims to investigate the reach and impact of two social prescribing services by using a mixed-methods approach which will include analysing secondary data from social prescribing management databases held by participating organisations, workshops, focus groups and interviews. Participants will include professionals involved in commissioning, delivery and monitoring and evaluation roles related to social prescribing link workers and members of the public who have accessed social prescribing services. Observational data will also be collected during meetings and informal conversations with those involved in the project. The findings will be reviewed with participants to support the development of a larger research project to explore the effects of social prescribing on health inequalities in ways that are meaningful to stakeholders. In this presentation the findings will be presented and discussed loosely around the following questions: 1. What routinely collected outcome data is currently available to social prescribing researchers (locally, nationally and internationally)?; 2.What is missing from that data regarding meaningful outcomes in relation to health inequalities?; 3. How might social prescribing reduce or exacerbate health inequalities?

Abstract
Abstract
Background
High intensity statins are recommended in patients with acute coronary syndrome. Statins inhibit atherosclerotic plaque formation in the coronary arteries and reducing the burden of ischemic heart disease, therefore decreasing the morbidity and mortality. Muscle symptoms are most common adverse effect of statins. Hence, the aim of this study is to determine the statin induced myalgia by the statin myalgia clinical score.
Purpose
To monitor the Statin induced myalgia on high intensity statin in patients with Acute Coronary Syndrome
Methods
This was an prospective observational study comprised of 418 patients with acute coronary syndrome who were commenced on high intensity statins (Rosuvastatin 20–40mg & Atorvastatin 40–80). These patients were followed at 4 weeks, 8 weeks and 12 weeks subsequently and the clinical myalgia score (SAMS-CI) was calculated at each visit to determine the statin induced myalgia. SAMS-CI was categorized as unlikely (2–6), possible (7–8) and probable (9–11)
Results
From 418 patients, 327 were males and 91 were females. Mean age was 55.6±11.14. Only 19 (7.63±1.8) patients developed muscle symptoms on high intensity statins (Rosuvastatin 20 mg and Atorvastatin 40 mg) on SAMS-CI Score. 5 patients were unlikely to develop myalgia on SAMS-CI and continued with the same dosage without any new symptoms. 6 patients were possible on SAMS-CI, therefore the dosage of these patients were decreased to moderate intensity statin (Rosuvastatin 10mg, Atorvastatin 20 mg), their symptoms were resolved and continued with the moderate intensity statins. Furthermore, Statin was hold in 8 patients in the probable category for 4 weeks until the resolution of symptoms followed by moderate intensity statins.
Conclusion
Statin induced myalgia is more reported in old aged and female patients. Most of the patients can better tolerate the lower range of high intensity statins with the similar benefits and should be prescribed in every patient

Abstract
Abstract
Background
Transcatheter pulmonary valve implantation has emerged as an effective alternative to surgery in patients with congenital Right Ventricular Outflow Tract Dysfunction (RVOT). There is demonstrable evidence that Percutaneous Pulmonary Valve Implantation (PPVI) effectively restores conduit graft viability with a consequent improvement in right ventricular pressures.
Aim
The objective of this study was to perform a meta-analysis of all previously published studies examining the outcome of PPVI and the associated early and late peri-procedural factors in patients with RVOT dysfunction. Data from procedures performed within our own centre have also been included.
Methodology
We performed a meta-analysis of all observational studies investigating early and late outcomes following PPVI. Risk ratios and risk differences were pooled in a random-effects model. The I2 statistic was used to quantify heterogeneity between studies. We searched EMBASE, MEDLINE, CINAHL, PsychInfo and Cochrane databases from their inception until 2021. Studies were included if they reported any comparative data regarding study endpoints. Primary endpoint was mean RVOT gradient. Secondary end points include pulmonary regurgitation fraction, left and right ventricular end-diastolic and systolic volume indexes, and left ventricular ejection fraction. Complication rates were considered a safety endpoint.
Results
A total of 23 studies with 1501 participants enrolled were included in the final meta-analysis. The RVOT gradient decreased significantly [weighted mean difference (WMD) = −20.32 mmHg; 95% confidence interval (CI): −22.15, −19.11; p<0.001]. Mean right ventricular (RV) systolic pressures fell significantly [(WMD)= −18.4 mmHg; 95% CI: −16.4, −20.2; p<0.001) and RV diastolic pressures decreased significantly [(WMD) = −6.3 mmHg, 95% CI: −4.3, −8.9; p<0.001). Pulmonary regurgitation fraction (PRF) also decreased notably (WMD = −24.38%, 95% CI: −28.27, −17.32; p<0.001).The incidence of infective endocarditis was 1.8% (95% CI: 0.7–3.8).
Conclusion
PPVI is an effective and safe strategy in relieving right ventricular remodelling and improving haemodynamic and clinical outcomes in patients with RVOT dysfunction. Multi-centre collaborations are essential to further determine the long-term effects of PPVI on cardiac function, exercise tolerance and quality of life in RVOT dysfunction.

Abstract
Abstract
Aim
Abdominal aortic aneurysm repair was traditionally preformed with open surgical repair (OSR). Recently endovascular aneurysm repair (EVAR) has increased in popularity due to its less invasive nature particularly in those deemed unfit for OSR. The EVAR-2 trial found no significant difference between BMT and EVAR in the 30 days all-cause mortality. This questioned whether EVAR was the best option in those medically unfit for OSR.
Method
Elective EVAR procedures from the 1st April 2012 to 1st September 2017 were analysed with Kaplan-Meier graphs. The patient data was stratified by year, age group and EVAR risk scoring.
Results
The all-cause mortality at 30 days was 1.8%, at 6 months it was 7%, and at 4 years it was 19.8%. There was no significant difference with log rank analysis of the year of EVAR operation and consultant (P > 0.05). The log rank analysis found a significant difference between the stratified age groups (P < 0.001) and the EVAR scoring (P = 0.032). At all time-points the RLUH EVAR patients had a lower all-cause mortality compared to the EVAR-2. At the 4-year time point, the RLUH EVAR group had lower all- cause mortality than both EVAR-1 and EVAR-2 trials.
Conclusions
The retrospective audit data from 2012-2017, suggest the RLUH EVAR treatment practice is not falling into the EVAR-2 trial findings. At all time-points the RLUH EVAR patients had a lower all-cause mortality compared to the EVAR-2. Therefore, it can be concluded the RLUH is not treating EVAR-2 patients.

Abstract
Abstract
Aim
Digital Rectal Examination (DRE) is an essential component of comprehensive assessment of a surgical patient, both in acute and elective settings. Due to the intimate nature of the examination, this important examination is often not well taught. This study aims to assess the confidence and knowledge of the Foundation Year 1 (FY1) doctors in performing DRE.
Method
FY1 doctors were invited for online voluntary anonymous survey via Google forms. The survey consisted of 16 questions on the indications, findings, and interpretation of DRE. The purpose and aims of the study were explained in an invitation email and participants provided a declaration of consent, giving permission for their anonymous results to be used in the study.
Results
There were 24 responses, 79% had performed DRE (including on mannequins and simulations) less than 10 times. Two thirds of DRE were performed during the FY1 rotation and two thirds in the elective wards. Majority of respondents (83%) were moderately confident in performing and appreciating DRE findings. 63% respondents though that a chaperone is not mandatory if the gender of the doctor and patient was same. 58% respondents thought that hematuria is not an indication to preform DRE. Interpretation of DRE findings - approximately 80% respondents correctly interpreted the findings, however only 45% could formulate the correct initial management plan.
Conclusions
This study illustrates that FY1 doctors receive inadequate exposure to performing and interpreting DRE. Their teaching should be enhanced by providing them with more opportunities through simulation and dedicated teaching sessions.

Abstract
Abstract
Aim
Covid-19 has significantly disrupted elective and emergency health care provision including cancer care within the UK. The aim of the study was to investigate the impact of the pandemic on the staging of oesophago-gastric cancers at presentation, determine the time delay in performing gastroscopy and the multidisciplinary team (MDT) treatment outcomes.
Method
A retrospective cohort study of all newly diagnosed oesophago-gastric cancers (adenocarcinoma and squamous cell carcinoma) in a single regional MDT was performed between 1st October 2019 and 30th September 2020. Electronic records were interrogated and patients dichotomised into two groups with those presenting before the introduction of the UK national lockdown of 23rd March 2020 compared to those presenting post-lockdown.
Results
349 new oesophago-gastric cancer patients were discussed in the MDT (192 pre-lockdown versus 157 post-lockdown). Demographics were evenly matched between the two groups. More patients presented as an emergency admission post-lockdown (28.0% vs 12.5%, p < 0.001). Median waiting time for gastroscopy was longer post-lockdown (23 vs 14 days, p = 0.035). Metastatic disease at presentation was more frequent post-lockdown (47.8% vs 33.3%, p = 0.008). Overall, more patients had a palliative rather than curative treatment intent post-lockdown (71.3% vs 57.8%, p = 0.005).
Conclusions
The Covid-19 pandemic has had a significant negative effect on the stage of oesophago-gastric cancers at presentation. This has translated into more patients receiving palliative treatment and ultimately having a poorer prognosis. This study highlights the importance of maintaining cancer services during Covid-19 pandemic.

Abstract
Abstract
Aim
Local field potentials (LFP) are gathered when deep brain stimulation (DBS) electrodes are inserted into subcortical structures; however, the clinical application of these findings are unclear.
Method
A literature search was conducted using PRISMA guidelines, 231 papers were analysed for the literature review.
Results
The lack of dopamine in Parkinson’s disease (PD), is thought to increase the sensitivity of the basal ganglia-thalamo-cortical network to rhythmic oscillatory inputs causing pathological oscillations. Beta band frequency oscillations have been strongly linked to bradykinesia and rigidity in Parkinson’s disease patients. Whereas gamma oscillations were found to be prokinetic and possibly related to normal physiology. There has been varying views on LFP findings and tremor pathology, recent research has suggested a link between the ratio of slow and fast oscillations increasing resulting in a tremor. Studies found contradicting results with pathological oscillations, reasons for the variation include the time of the LFP recordings and the placement of the electrodes. The use of LFP presents a promising new technology namely adaptive deep brain stimulation (aDBS). aDBS has not been tested long-term in human patients, the safety and effectiveness long-term is unknown.
Conclusions
aDBS provide an exciting new technology however, the current evidence base provides a proof-of- principle, there are still many issues which need to be addressed before this can become an established treatment. With technological advances aDBS could revolutionise PD treatment and if perfected could potentially abolish patient’s symptoms completely.

Abstract
Abstract
Aim
Over the last decade, quality performance indicators (QPIs) have been used to drive improvements in cancer care in Scotland. QPI-11 targets curative treatment rates for oesophago-gastric (OG) cancer and this target has been consistently missed. This study aimed to investigate why patients with potentially curable Stage I and II OG cancer did not receive curative treatment in the West of Scotland.
Method
The West of Scotland MCN database was interrogated for patients with newly diagnosed stage I and II OG cancer between January 2018 and December 2019 to identify those patients who did not have curative treatment. Electronic records were then analysed.
Results
81 patients (mean age of 79.3 ± 8.9 years; 41 (50.6%) female) were identified. Median Scottish Index of Multiple Deprivation was 3 (IQR 1-7). There were 46 (56.8%) oesophageal cancers, 49 (60.5%) adenocarcinomas and 63 (77.8%) were Stage II cancers. Formal CPEX fitness was assessed in only 6 patients (7.4%). Reasons for curative treatment not being received were as follows: not clinically fit (n = 69 (85.2%)); patient declined curative treatment (n = 7 (8.6%)); disease progression (n = 3 (3.7%)) and identification of synchronous cancers (n = 2 (2.5%)). 61 patients (75.3%) are deceased at the time of analysis, with a median time from MDT discussion to death of 6 (IQR 2-11.5) months.
Conclusions
Lack of fitness for radical treatment is the predominant reason for Stage I and II OG cancer patients in the West of Scotland not being treated with curative intent. This may be related to the previously described “West of Scotland” effect on health comorbidities.

Abstract
Aim COVID19 produced a unique challenge to the management of hand trauma. There was reduced theatre capacity and inpatient beds as staff and resources were lost to make way for the critically unwell1, however the burden of patients (albeit reduced) requiring emergency procedures remained2. During 1stUK peak we adopted a one-stop hand trauma clinic where patients were assessed by senior surgeons and immediately operated on under local anaesthesia with Adrenalin, a model mirrored by other units across the UK during this time3,4. Subsequent to surgery they were either seen on the same day for advice with a hand therapist or booked for immediate hand therapy follow up. Method A retrospective review of 158 cases operated on over a 4-month COVID19 period compared to the same 4-month period 1 year previously. Indications for surgery and type of anaesthesia were recorded. Follow up and complication rates were reviewed for the COVID19 patients. Results There were similarities in the demographic of patients across both cohorts and in mechanism of injury, with trauma the highest indication for surgery. The comparable data sets showed only 21% of patients treated used WALANT pre-COVID19 versus 100% of patient during COVID19. Conclusions WALANT is a viable model by which to perform emergency hand trauma surgery in a low cost and low resource setting. Previously this model was not utilised to full effect in our hospital. The results demonstrate the adaptability of WALANT in an adverse and dynamic situation, such as COVID19, thus highlighting benefits to patient care and service provision.

Abstract
Abstract
Aim
Hull University teaching hospitals NHS trust has guidelines for patient fasting times prior to major elective surgery. We aimed to assess the compliance of pre-op fasting times for patients undergoing elective colorectal surgery.
Method
An initial and later re-audit was undertaken, prospectively, of 20 consecutive patients admitted for elective colorectal surgery at Castle Hill Hospital. Data was collected on a structured proforma and was completed following patient’s interview, ORMIS (operation room system) and Lorenzo (hospital intranet).
Results
Initial audit demonstrated 10% (2 out of 20) and 5% (1 out of 20) compliance with liquid and solid fasting times, respectively. Following implementation of changes, re-audit demonstrated 60% (12 out of 20) and 0% (0 out of 20) compliance with liquid and solid fasting times respectively
Conclusions
We concluded that liquid fasting times can be improved further by communication between theatre staff and ward. Whilst solid fasting times can be improved but at an expense of losing a theatre space. A further re-audit [planned in a month period.

Abstract
Abstract
Aim
The ‘Basket-in-catheter’ (BIC) technique facilitates laparoscopic transcystic ductal exploration (LTCE) and increases its success rate, being easier and safer than inserting the basket alone. This study evaluates the benefits in confirmed and suspected ductal stones.
Method
Prospective preoperative, operative and postoperative data on consecutive single session ductal explorations was collected over 28 years and analysed. BIC became our default technique for the transcystic approach to confirmed or suspected bile duct stones.
Results
741 of 1225 (60.5%) attempted LTCE were performed using retrieval baskets without dilating the cystic duct (CD). BIC was used in 646 (87.2%). Of 386 (52.1%) patients undergoing successful stone retrieval 62.7% had clinical and radiological risk factors for ductal stones and 92.0% had positive intraoperative cholangiography. 355 (47.9%) patients had preoperative or operative risk factors for CBD stones and equivocal cholangiography in 25%. Basket trawling was negative and repeat cholangiography confirmed resolution of abnormalities. Choledochoscopy was utilised in 484/1225 (39.5%), either primarily or when blind trawling failed to extract stones. Retained stones occurred in 7 patients, six requiring ERCP. Bile leakage occurred in 6 patients. There were two open conversions, no biliary injuries and no mortality. Post-operative pancreatitis occurred in 7 and recurrent stones in 8 patients.
Conclusions
The BIC technique achieves successful LTCE without CD dilatation in 40%, reducing the need for choledochoscopy and choledochotomy. It facilitates safe and speedy CBD trawling when stones are suspected due to preoperative or operative risk factors or equivocal cholangiography and helps surgeons acquire and consolidate ductal exploration skills.

Abstract
Abstract
Aim
The COVID-19 pandemic has caused significant disruption in surgical training. We aim to explore the preferences of higher general surgical trainees for Annual Review of Competency Progression (ARCP) also compare the responses across different training grades.
Method
All higher general surgical trainee in a single deanery were invited to participate in an online voluntary anonymous survey. The respondents were divided in two groups: junior (ST3-ST5) and senior higher surgical trainees (ST6-ST8) and responses compared.
Results
Sixty-four of 88 trainees responded. Thirty-three (51.6%) were ST3–ST5, 24 (37.5%) were ST6–ST8 and 7 (10.9%) were out-of-training. More trainees in ST3–ST5 group preferred to defer the next rotation for 12 months (18.2% vs 0%, p = 0.034), repeat current sub-specialty (33.3% vs 4.2%, p = 0.009), or add 12 months to training and delay predicted CCT date by 12 months (18.2% vs 0%, p = 0.034). Most trainees in both groups preferred the option of prolonging training should be offered to all trainees with an option to decline extension if ARCP competencies met (66.7% vs 50.0%, p = 0.276).
Conclusions
The preference for ARCP and length of training was different between two training groups, hence the need of trainees should be considered by training committees when addressing the impact of COVID-19.

Abstract
Human brucellosis is a neglected zoonotic problem worldwide with a high degree of morbidity in humans and is mostly overlooked due to other febrile conditions. The aim of this study was to evaluate the sero-prevalence and risk factors of human brucellosis among subjects living in Punjab, Pakistan. In this cross-sectional study, human blood samples were collected from seven districts of Punjab, Pakistan. Information regarding personal data, demographic data and potential risk factors was collected through a structured questionnaire. Detection of anti-Brucella antibodies was done through Rose Bengal Plate Test (RBPT) and Enzyme Linked Immunosorbent Assay (ELISA). Descriptive analysis, Chi square test and Odds ratio was applied using STATA software version 12. The sero-prevalence of human brucellosis was 13.13% with significantly higher percentage in males 17.23% and age group 25-40 years 16.50% (P=< 0.001). The demographic factors positively associated with human brucellosis were lack of education (P = 0.003; OR = 1.85) and farming as an occupation (P =<0.001; OR = 2.50) Similarly, among the risk factors studied, keeping animals at home (P =<0.001; OR = 2.03), slaughtering of animals (P =<0.001; OR = 15.87) and consuming raw milk (P =<0.001; OR = 5.42) were the factors strongly connected with human brucellosis. A massive awareness should be given to livestock farmers and individuals directly linked to animals regarding risk factors and transmission of brucellosis. Consumption of unpasteurized milk and its products should be condemned to curtail this neglected disease.

Abstract
Abstract
Study question
Does endogenous progesterone play a role in unexplained infertility? A systematic review investigating the possibility of altered progesterone-mediated change leading to reduced endometrial receptivity in women with unexplained infertility.
Summary answer
The evidence suggests that many of the measurable actions of endogenous progesterone are reduced in women with unexplained infertility when compared with controls.
What is known already
Unexplained infertility is the diagnosis given to heterosexual couples who fail to conceive despite normal semen analysis, regular ovulation and patent tubes. The underlying pathology is likely to relate to embryonic failure to implant. Endometrial receptivity is largely mediated by luteal phase progesterone which controls many different molecular pathways involved in secretory transformation. It is possible that defective actions of progesterone could contribute to this condition. To date however, there is minimal published literature on the role of progesterone in unexplained infertility. We therefore felt it important to combine the results of all trials measuring progesterone-related outcomes in unexplained infertility.
Study design, size, duration
A systematic review was performed using standard Cochrane methodology. We searched Medline, Embase and CINAHL databases from inception to December 2020 and additionally hand-searched. The study was prospectively registered on Prospero (CRD42020141041). The search strategy was designed to identify all types of primary research published in English that investigated women with unexplained infertility and reported outcomes that relate to progesterone. Newcastle Ottawa Scoring and NHLBI assessment of bias scoring was performed.

The study population was women with unexplained infertility. Included studies had no controls, fertile controls or controls with other diagnoses associated with subfertility. Outcomes were either upstream affecting progesterone production/release or receptor expression or downstream measuring results of progesterone-mediated processes. The results were summarised in a narrative review. Meta-analysis was not possible due to varying methodological heterogeneity.
Main results and the role of chance
36 studies were included. No difference was found in 18 studies in progesterone levels (serum, peritoneal and salivary) between women with unexplained infertility and control groups. Despite this, 32 of the 36 included studies demonstrated a significant difference between progesterone-mediated outcomes in the unexplained infertile and control groups.
5 ultrasound studies all reported increased resistance and decreased flow on doppler studies of uterine, ovarian and spiral arteries and reduced endometrial and sub-endometrial perfusion. No significant difference was found in luteal phase endometrial thickness in 2 studies.
Endometrial dating was reported by 11 studies. 8/11 studies reported significantly higher numbers (20–38%) of ‘out-of-phase’ endometrium in women with unexplained infertility compared with controls.
Endometrial biopsy results measuring different cell adhesion molecules, monoclonal antibodies and other molecules involved in endometrial transformation as well as expression of responsible genes and steroid hormone receptors were included. All the progesterone-mediated outcome measures listed above were reduced in unexplained infertile women except β3 integrin which reported contradictory results and SGK1 expression which was reported in 1 study. This trend towards support for the hypothesis may be more important than any individual finding. The quality of the included studies was variable and hence the strength of the recommendations moderate.
Limitations, reasons for caution
The number of studies measuring each outcome was limited. The study quality varied from good to poor. Methodological heterogeneity between studies prevented meta-analysis. The strength of the study however comes from the originality of the research, the variety of included outcomes and that 32/36 papers reported results supporting the hypothesis.
Wider implications of the findings: The findings of this systematic review support the need for larger, well designed research on this topic. If altered progesterone-mediated receptivity is implicated in unexplained infertility, it may be possible to offer other therapeutic interventions to improve outcomes as an alternative or adjunct to standard fertility treatment.

Abstract
Abstract
Introduction
The Giant Hogweed (Heracleum mantegazzianum) is a rare cause for chemical burns in humans and animals and is acquiring growing recognition in mainstream media as a relevant public health concern.
Injuries attributed to this plant range from innocuous superficial irritation to full-thickness chemical burns. A vast majority of cases will resolve with conservative measures and effective first aid, but these case series demonstrate the clinical course of more severe injuries.
Description
We present a case series of 2 patients requiring admission to the Royal Group Hospitals for management of mixed thickness hogweed burns. Injuries were sustained by two separate infestations of giant hogweed in the Western Trust Area. Both patients responded to observation and conservative measures, namely effective analgesia, UV light protection, topical hydrocortisone, and dressings.
Discussion
Cutaneous burns induced by giant hogweed are caused by contact with its photoactive sap containing plant furocoumarins. On exposure to sunlight, the sap initiates a damaging process known as phytophotodermatitis (PPD). This process can be managed effectively with topical steroids; however, prolonged contact and subsequent sun exposure may lead to more severe skin damage. In extremely rare instances, damage may progress to full-thickness skin burns warranting operative intervention.

Abstract
Toxoplasma gondii is a protozoan parasite that can infect all mammals, serving as intermediate hosts. The cause of congenital toxoplasmosis is transplacental transmission of the parasite to the foetus, resulting in wide range of manifestations from mild chorioretinitis to miscarriage. Its frequency can be reduced by early screening of pregnant women which is based mainly on tests for anti-Toxoplasma antibodies. We collected serum samples of 594 pregnant women (subjects) after taking their consent over a period of two years (2016-2018) and analyzed them for anti-Toxoplasma IgG by ELISA. The positive samples were then analyzed for IgG avidity test which could differentiate between recent and past infections. The seroprevalence was also correlated with the age of the subjects and their contact with cats. 162 subjects were found positive out of which only three showed a recent infection. After following up until delivery, one of them delivered a baby who had jaundice and was diagnosed with anti-Toxoplasma IgM at birth. The foetus of the second subject died in-utero, while the third woman delivered a normal baby after being given spiramycin when diagnosed with toxoplasmosis in the first trimester. It was found that most of the positive subjects had frequent contact with cats. Invasion of the parasite during third trimester resulted in death in-utero and jaundice. Most common cause of pregnancy wastage during our study was spontaneous abortions while pregnancy loss due to congenital anomalies was rare.

Abstract
Abstract
Background
Coronary artery calcium (CAC) is a marker of atherosclerosis and an independent risk factor for cardiac-related mortality. The measurement of this score has traditionally been based on using ECG triggered computed tomography (CT). However, CAC, identified on non-contrast high resolution chest computed tomography (HRCT), should be considered diagnostic for coronary artery disease (CAD). We aimed to evaluate the incidental prevalence and burden of CAC on non-gated HRCT thorax used for patients undergoing lung cancer screening or follow-up for interstitial lung disease. We also assessed how often Radiologists reported CAC as an incidental finding on these scans.
Methods
Computerised Radiology Information Service (CRIS) was manually searched to determine all HRCT scans performed in our Trust from 01/05/2018 to 01/05/2019. The reports issued by Radiologists and images of selected studies were reviewed.
Results
2185 HRCT scans were performed over this period. Patients were divided into three groups of age <50 (Group 1); 50-<60 (Group 2) and 60 (Group 3). 100 scans were randomly selected from each group using a random number generator to give a total of 300 patients. The mean ages of patients in Group 1, 2 and 3 were 48.3±2.3, 54.8±2.4 and 65±3.2 respectively. There was, approximately, the same number of males as females in each group. CAC was noted in 15% of scans in Group 1, 82% of scans in Group 2 and 94% scans in Group 3. CAC was only noted in 1/15 (6.7%) of scan reports in Group 1, 41/82 (50%) in Group 2 and 37/94 (39.4%) in Group 3. Among the 79 patients with radiologist-reported incidental CAC, statin and aspirin prescriptions increased by approximately 7 percentage points each. A diagnosis of CAD was eventually made in 9 (11.4%) patients through functional imaging or coronary angiogram. Two authors independently calculated the Agatston scores of HRCT scans whose reports did not comment on the degree of calcification. We excluded 15/112 (13.4%) scans as they were uninterpretable due to motion artefacts. Of the remaining 97 scans analysed 58/97 (59.8%) had severe CAC with an Agatston score of >400 with the remaining showing moderate calcification (101–400). Cohen κ agreement between the two authors rating was 0.90 (95% confidence interval [CI] 0.87–0.96). Group 2 and 3 had significantly more patients with severe CAC then group 1 (p<0.001). Left anterior descending artery was most commonly affected.
Conclusion
This study shows that CAC is under reported on non-gated HRCT scans which represents a missed opportunity to implement strategies for primary and secondary prevention. Given that respiratory disease is an independent risk factor for developing cardiac disease, it is incumbent upon the interpreting clinician to report all findings and ensure that critical findings are highlighted. The images of calcified coronary arteries may also potentially have a role in convincing people to make correct lifestyle choices.

Abstract
Abstract
Background
There is existing evidence to suggest a correlation between coronary artery calcification (CAC) measured using ECG-triggered chest computed tomography and cardiovascular disease. Further evidence has emerged to suggest a correlation between CAC measured using non-gated CT scans and cardiovascular disease. Herein, we sought to ascertain the utility of incidental findings of CAC on non-triggered high resolution CT (HRCT) thorax used for patients undergoing lung cancer screening or follow-up for interstitial lung disease and Framingham risk score (FRS) in predicting cardiovascular events.
Methods
The Computerised Radiology Information Service (CRIS) database was manually searched to determine all HRCT scans performed in a single trust from 05/2015 to 05/2016. The reports issued by Radiologists and images of selected studies were reviewed. For patients with CAC, we calculated the calcium score for patients using the Agatston method. Clinical events were determined from the electronic medical record without knowledge of patients' CAC findings. For these patients, the Framingham Risk Score (FRS) was also calculated. The primary end point of the study was composite of all-cause mortality and cardiac events (non-fatal myocardial infarction, coronary revascularization, new atrial fibrillation or heart failure episode requiring hospitalization).
Results
We selected 300 scans from a total of approximately 2000 scans performed over this time. Data at follow up was available for 100% of the patients, with a median duration of follow up of 1.6 years. Moderate to severe CAC was found in 35% of people. Multivariable analysis showed good concordance between CAC and FRS in predicting composite clinical end point. The Odds Ratio for cardiac events in patients with moderate to severe CAC was 5.3 (p<0.01) and for composite clinical end point was 3.4 (p<0.01). This is similar to the OR predicted by the FRS: 4.8; p<0.01 and 3.1; p<0.01 respectively. Only 6.2% of patients with moderate to severe CAC were currently statin treated.
Conclusion
In this retrospective study of patients with respiratory disease attending for HRCT scanning, co-incidentally detected CAC predicts cardiac events, with good concordance with the FRS. The incidental finding of CAC on non-gated CT scanning should be reported with Agatston score calculation allowing consideration of intervention to mitigate cardiovascular risk and optimize. Further multi-centre prospective studies of this strategy, with a larger patient cohort should be conducted to clarify the utility of CAC as a prediction tool to modify cardiac risk.
