Abstract
Aim To gain an understanding of the impact of COVID-19 on the daily life, healthcare needs, mental wellbeing and outlook of patients with Interstitial Lung Disease (ILD) and their caregivers. Methods ILD patients and caregivers were invited to participate in a quantitative survey. Respondents could self-select to then participate in in-depth structured telephone interviews. Survey data was compared to Department of Health COVID-19 public opinion tracker findings for the comparable time period. Results There were 170 survey respones (111 patients and 59 caregivers) and 14 in-depth interview participants. 32% (n=36) of patients and 42% (n=25) of caregivers expressed extreme worry regarding COVID-19 on a 1-10 scale. 83% (n=92) of patients expressed concern about safe hospital access, 33% (n=37) had received a telephone consultation with their clinician, 43% (n=48) reported test delays, 47% (n=52) were exercising less, 23% (n=26) reported worse sleep and 15% (n=17) reported being financially worse off. Carers reported that sleep was worse for 58% (n=34), 42% (n=25) reported being worse off financially, and 40% (n=24) reported a worse diet. Worry (66%, n=39), stress (51%, n=30), anxiety (49%, n=29) were commonly reported by carers. Discussion ILD patients and caregivers reported higher levels of worry regarding COVID-19 compared to the general public. Alternative pathways for quality ILD patient care and interventions to reduce the burden of care on ILD caregivers are required.

Abstract
BACKGROUND RCS Eng, the Royal College of Surgeons of England, has published much information with regard to the consenting process. A majority of patients seek health information through online resources as well as discussing with the care givers. Therefore, it is necessary that online material is both of high quality and reliable for patients. We aimed to evaluate the quality and standard of the online patient information on laparoscopic cholecystectomy to help in the consenting process. METHODS A search was carried out as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Sources were assessed using five validated scoring tools: Flesch-Kincaid Reading Ease Score (readability), DISCERN and IPDAS scores (quality of content) and HONcode and the Information Standard Certification (standards of accreditation). RESULTS The average readability of all websites was higher than recommended for patient literature. Less than half of the sources had received HONcode or Information Standard accreditation. On grading of quality and content, across validated scoring tools, no source achieved the minimum recommended level. CONCLUSION Online patient information related to laparoscopic cholecystectomy is of poor quality. We recommend a multidisciplinary approach to participate in publishing more readable online resources of a higher standard to help patients and clinicians in consent and shared decision making.

Abstract
Abstract
Introduction
There is conflicting evidence on the benefit of statins for primary prevention of cardiovascular disease (CVD) in non-diabetics over 75. Emerging evidence shows they may be ineffective, yet current guidance supports their use in those up to 85. The objectives of this study were to assess patients’ understanding of statins, willingness to participate in a theoretical randomised controlled trial (RCT), where they would be randomised to stop their statin and to compare the trial population with national data.
Methods
The survey took place in 8 GP practices with 4 students involved in questionnaire distribution. A patient search identified those over 75 and on a statin. Patients were excluded if they had a history of CVD or diabetes. 36 patients were identified and completed questionnaires, 5 were removed because they reported exclusion criteria. Demographic data was compared to the UK population from the 2011 census.
Results
Of 31 participants, 71% understood why they took statins, most were unconcerned about side effects and only 1 patient stopped statins due to the media. Opinions on the theoretical “stopping statins trial” were varied. 35% of people responded positively. 29% would not want to take part and 36% of people were unsure. Comparison of our trial population against the national population shows that 903,505 people would be eligible for a UK trial.
Conclusions
The purpose of this exercise was to see if patients would be willing to participate in a trial where 50% stopped taking their statin. Approximately a third said yes and only a third said no. As there are nearly a million people in this population, it suggests a fully funded, larger-scale feasibility study of this theoretical randomised control trial is warranted.

Abstract
Abstract
Introduction
Emerging research suggests that statin use for primary prevention in people without diabetes aged 75 and older has no benefit. This study aims to determine the feasibility of the theoretical Stop Statin Study (3S), a double-blind randomised controlled trial carried out in general practice, which would test this hypothesis. 50% of trial patients would stop taking statins for 5 years in an event driven study. The questionnaires aim to identify the attitudes of general practitioners (GPs) and ethics committee members (ECMs) regarding stopping statins for 5 years in patients aged 75 and older without diabetes or history of cardiovascular disease and their willingness to allow patients to participate in the 3S study.
Method
Questionnaires comprised of 6 questions were designed. 4 students distributed the questionnaire and it was completed by 19 GPs based at 8 practices in the North-East of England. 31 ECMs (12 expert and 19 lay) responded by email.
Results
95% of GPs who completed the survey would agree to their patients participating in the theoretical study with 47% of GPs indicating that their willingness to participate in the study is patient dependent. 95% of GPs would also consider stopping statins in this population group if sufficient research had been carried out or if the guidelines were changed. 42% of GPs have a negative attitude to prescribing statins in this population group. All the ECMs would approve the study, citing over-prescribing and polypharmacy as their reason.
Conclusions
The majority of GPs will participate in the theoretical 3S study, if their patients are willing to participate. There is already a negative perception amongst GPs towards the use of statins in elderly people without disease. The 3S study appears to be feasible from the GP and ethics perspective but would require a larger feasibility study.

Abstract
Cities are wrestling with the practical challenges of transitioning urban water services to become water sensitive; capable of enhancing liveability, sustainability, resilience and productivity in the face of climate change, rapid urbanisation, degraded ecosystems and ageing infrastructure. Indicators can be valuable for guiding actions for improvement, but there is not yet an established index that measures the full suite of attributes that constitute water sensitive performance. This paper therefore presents the Water Sensitive Cities (WSC) Index, a new benchmarking and diagnostic tool to assess the water sensitivity of a municipal or metropolitan city, set aspirational targets and inform management responses to improve water sensitive practices. Its 34 indicators are organised into seven goals: ensure good water sensitive governance, increase community capital, achieve equity of essential services, improve productivity and resource efficiency, improve ecological health, ensure quality urban spaces, and promote adaptive infrastructure. The WSC Index design is a quantitative framework based on qualitative rating descriptions and a participatory assessment methodology, enabling local contextual interpretations of the indicators while maintaining a robust universal framework for city comparison and benchmarking. The paper demonstrates its application on three illustrative cases. Rapid uptake of the WSC Index in Australia highlights its value in helping stakeholders develop collective commitment and evidence-based priorities for action to accelerate their city's water sensitive transition. Early testing in cities in Asia, the Pacific and South Africa has also showed the potential of the WSC Index internationally.

Abstract
Anti-Ro60 is one of the most common and clinically important serum autoantibodies that has a number of diagnostic and predictive capabilities. Most diagnostic laboratories report this simply as a qualitative positive/negative result. The objective of this study was to examine the clinical and serological relevance of a novel subset of anti-Ro60 in patients who display low levels of anti-Ro60 (anti-Ro60low ). We retrospectively identified anti-Ro60 sera during a 12-month period at a major immunopathology diagnostic laboratory in Australia. These all were anti-Ro60-precipitin-positive on the diagnostic gold standard counter-immuno-electrophoresis (CIEP). Lineblot immunoassay was used to stratify patients into either anti-Ro60low or anti-Ro60high subsets. We compared the medical and laboratory parameters associated with each group. Enzyme-linked immunosorbent assay (ELISA) and mass spectrometry techniques were used to analyse the serological and molecular basis behind the two subsets. Anti-Ro60low patients displayed less serological activity than anti-Ro60high patients with less intermolecular spreading, hypergammaglobulinaemia and less tendency to undergo anti-Ro60 isotype-switching than anti-Ro60high patients. Mass spectrometric typing of the anti-Ro60low subset showed restricted variable heavy chain subfamily usage and amino acid point mutations. This subset also displayed clinical relevance, being present in a number of patients with systemic autoimmune rheumatic diseases (SARD). We identify a novel anti-Ro60low patient subset that is distinct from anti-Ro60high patients serologically and molecularly. It is not clear whether they arise from common or separate origins; however, they probably have different developmental pathways to account for the stark difference in immunological maturity. We hence demonstrate significance to anti-Ro60low and justify accurate detection in the diagnostic laboratory.

Abstract
INTRODUCTION Enhanced recovery programmes are established as an essential part of laparoscopic colorectal surgery. Optimal pain management is central to the success of an enhanced recovery programme and is acknowledged to be an important patient reported outcome measure. A variety of analgesia strategies are employed in elective laparoscopic colorectal surgery ranging from patient-controlled analgesia to local anaesthetic wound infiltration catheters. However, there is little evidence regarding the optimal analgesia strategy in this cohort of patients. The LapCoGesic study aimed to explore differences in analgesia strategies employed for patients undergoing elective laparoscopic colorectal surgery and to assess whether this variation in practice has an impact on patient-reported and clinical outcomes. MATERIALS AND METHODS A prospective, multicentre, observational cohort study of consecutive patients undergoing elective laparoscopic colorectal resection was undertaken over a two-month period. The primary outcome measure was postoperative pain scores at 24 hours. Data analysis was conducted using SPSS version 22. RESULTS A total of 103 patients undergoing elective laparoscopic colorectal surgery were included in the study. Thoracic epidural was used in 4 (3.9%) patients, spinal diamorphine in 56 (54.4%) patients and patient-controlled analgesia in 77 (74.8%) patients. The use of thoracic epidural and spinal diamorphine were associated with lower pain scores on day 1 postoperatively (P < 0.05). The use of patient-controlled analgesia was associated with significantly higher postoperative pain scores and pain severity. DISCUSSION Postoperative pain is managed in a variable manner in patients undergoing elective colorectal surgery, which has an impact on patient reported outcomes of pain scores and pain severity.

Abstract
Abstract
Introduction
Systolic right ventricular (RV) function has prognostic significance both in acquired and congenital heart diseases. However accurate assessment of RV ejection fraction (EF) with transthoracic echocardiography (TTE) remains challenging due to the complex geometric shape of the RV. Magnetic resonance imaging (MRI) remains the gold standard modality for assessment of RV function; however the cost and availability limits the regular use of MRI in clinical practice. The RV strain measured by speckle tracking (RVS) is a novel method of assessing RV EF.
Purpose
The purpose of the study was to assess the accuracy of RVS compared RV fractional area change (FAC%), tricuspid annular peak systolic excursion (TAPSE) and Doppler tissue imaging-derived isovolumic acceleration and peak systolic velocity (S') at the lateral tricuspid annulus in the assessment of impaired RV EF.
Methods
We retrospectively identified patients who had a cardiac MRI between 2012- 2017 and only included patients with a TTE within 1 month of the MRI for our final analysis. Baseline characteristics, TTE and MRI parameters were extracted from chart review. RV strain was measured retrospectively using ECHOINSIGHT software. Four TTE parameters including RVS, TAPSE, S' and FAC% were tested for accuracy to identify impaired RV EF (defined as EF<45%) using receiver operator curves.
Results
The study cohort included 500 patients with mean age 55 yr ± 18 and right ventricular systolic pressure 33.7±13.6 mmHg. The proportion of female gender, diabetes, hypertension and obstructive sleep apnea were 38%, 15.6%, 43% & 19.8% respectively. The area under ROC for TAPSE, S', FAC% and RVS were 0.58 (95% confidence interval [CI] 0.51–0.65, p=0.03), 0.59 (95% CI 0.52–0.66, p=0.03), 0.67 (95% CI 0.61–0.73, p=0.03) and 0.70 (0.64–0.76, p=0.03) for assessing RV EF <45%.
Conclusion
Right ventricular strain most accurately detected impaired right ventricular ejection fraction as obtained by MRI.

Abstract
The process of surface mining and extracting bitumen from oil sand produces large quantities of tailings and oil sands process-affected water (OSPW). The industry is currently storing OSPW on-site while investigating strategies for their detoxification. One such strategy relies on the biodegradation of organic compounds by indigenous microbes, resulting in aged tailings waters with reduced toxicity. This study assessed the toxicity of OSPW aged statically for approximately 18 years. Dissolved organics in aged OSPW were fractionated using a preparative solid-phase extraction method that generated three organic fractions (F1-F3) of increasing polarity. Eight aquatic species from different trophic levels were exposed to whole OSPW (WW) and the derived OSPW organic fractions to assess toxicity: Pimephales promelas, Oryzias latipes, Vibrio fischeri, Daphnia magna, Lampsilis cardium, Hyalella azteca, Ceriodaphnia dubia, and Hexagenia spp. Broad comparisons revealed that P. promelas and H. azteca were most sensitive to dissolved organics within aged OSPW, while WW was most toxic to L. cardium and H. azteca. Three cases of possible contaminant interactions occurred within whole OSPW treatments, as toxicity was higher than organic fractions for H. azteca and L. cardium, and lower for P. promelas. As such, the drivers of toxicity appeared to be dependent on the species exposed. Of the organic fractions assessed, F3 (most polar) was the most toxic overall while F2 (intermediate polarity) displayed little toxicity to all species evaluated. This presents strong evidence that classical mono-carboxylic naphthenic acids, mostly present in F1 (least polar), are not primarily responsible for the toxicity in aged tailings. The current study indicates that although the aged tailings source (≥18 years) did not display acute toxicity to the majority of organisms assessed, inorganic components and polyoxygenated organics may pose a persistent concern to some aquatic organisms.
