Abstract
Objectives Suboptimal dosing of angiotensin-converting enzyme inhibitors and β-blockers limits the mortality benefit for acute coronary syndrome patients. Recent National Institute for Health and Care Excellence (NICE) guidelines emphasise prompt initiation and up-titration from inpatient to community care to achieve this. The aim of this study was to assess the impact of simple interventions on inpatient and community up-titration of bisoprolol and ramipril for acute coronary syndrome patients admitted to Leeds General Infirmary. Methods An initial prospective audit of 37 acute coronary syndrome patients admitted to Leeds General Infirmary in January 2013 assessed inpatient up-titration of bisoprolol and ramipril, discharge advice and doses at 6 weeks after discharge. Following a collective multidisciplinary effort with education, posters and discharge advice templates, a re-audit of 34 acute coronary syndrome patients admitted from November to December 2014 assessed the impact of these interventions. The independent samples t test was used to compare the mean difference between doses of ramipril and bisoprolol from initiation to discharge to dose at 6 weeks after discharge before and after intervention. Results There was a statistically significant improvement in the mean difference from initiation to discharge dose for both ramipril and bisoprolol (p=0.012 and p=0.017, respectively). However, there was little difference in community up-titration despite a 68% improvement in discharge advice. Conclusions Simple multidisciplinary interventions improved inpatient up-titration of ramipril and bisoprolol but continued up-titration to achieve the target doses remains a challenge in primary care. Acute coronary syndrome patients are precluded from maximum mortality benefit due to suboptimal dosing after discharge.

Abstract
We present a case of myocardial infarction in a 19 year old female with cystic fibrosis who had a heart and lung transplant performed at the age of four years old. She presented atypically with a one day history of severe, intermittent, central, sharp chest pain, radiating to her back and down her left arm. A coronary angiogram showed proximal stenosis of the left anterior descending artery and right coronary artery. She was treated with percutaneous coronary intervention, involving drug eluting stents to the left anterior descending artery (LAD) and the right coronary artery (RCA). In this study we discuss the pathophysiology, investigations and treatment of cardiac transplant vasculopathy. Although complete reversal of LAD and RCA stenosis was achieved, routine followup with coronary angiography and careful control of cardiac risk factors will be important to identify and reduce future restenosis and adverse cardiac events.

Abstract
BACKGROUND Inflammatory bowel diseases (IBD) require complex therapeutic decisions and life choices concerning pregnancy, but little is known about patient's knowledge of IBD and its treatment before and during pregnancy. AIM To develop a novel tool (Crohn's and Colitis Pregnancy Knowledge Score 'CCPKnow') to assess knowledge of pregnancy-related issues in IBD. The validated tool was then applied to determine knowledge in patients. METHOD Discriminate ability of 'CCPKnow' was validated in four groups with different levels of IBD knowledge. Reliability and readability were tested by Cronbach-α and Flesch-Kencaid. Construct validity was subsequently assessed against general IBD knowledge (CCKnow) in 145 women with IBD. Associations between patient factors and knowledge were studied. RESULTS Median CCPKnow scores differed significantly between the validation groups (P < 0.001). CCPKnow displayed excellent internal consistency, reliability (Cronbach-α 0.94), readability (reading age 9 years) and close correlation with CCKnow (Spearman's ρ 0.64; P < 0.001). Of 145 patients, 44.8% had poor, 27.6% adequate, 17.3% good and only 10.3% very good knowledge. Better knowledge was associated with Caucasian ethnicity, higher income, having a partner, having children, Crohn's and Colitis Association membership, longer disease duration and Crohn's disease. CONCLUSIONS Crohn's and Colitis Pregnancy Knowledge Score, a novel knowledge assessment tool of pregnancy and IBD, demonstrated excellent test characteristics. We found that nearly half of the women with IBD had poor knowledge, identifying a pressing need for better education.

Abstract
The risk of colorectal cancer for any patient with ulcerative colitis is estimated to be 2% after 10 years, 8% after 20 years and 18% after 30 years of disease. The relative risk of colorectal cancer in Crohn's colitis is approximately 5.6 and should raise the same concerns as in ulcerative colitis. Risk factors for colorectal cancer include disease duration, early onset, extensive disease, primary sclerosing cholangitis and a family history of sporadic colorectal cancer. All patients should have a review colonoscopy 8-10 years after diagnosis to establish the extent of the disease. Surveillance should begin 8-10 years after disease onset for pancolitis and 15-20 years after disease onset for left-sided disease. Regular surveillance is recommended, with a screening interval every 3 years in the second decade of disease and annually by the fourth decade. Random biopsies should be taken at regular intervals with attention paid to dysplasia-associated lesions or masses, irregular plaques, villiform elevations, ulcers and strictures. Dysplasia is recognized as a premalignant condition, but the likelihood of progression to cancer is difficult to predict. High-grade dysplasia, confirmed by two expert gastrointestinal pathologists, is a strong indication for colectomy, as is low-grade dysplasia, although the diagnosis of low-grade dysplasia is unreliable. Surveillance programmes indicate that the overall 5-year survival rate is higher in surveyed patients, although patients still present with Dukes C cancers or disseminated malignancy. Surveillance has huge socioeconomic implications. As surveillance is not 100% effective, alternative ways of reducing the cancer risk with chemopreventive agents, such as aminosalicylates, are being considered.

Abstract
The chemoprevention of colorectal cancer (CRC) with long-term sulfasalazine and 5-aminosalicyclic acid (5-ASA) treatment has been demonstrated through epidemiological and experimental studies, in patients with ulcerative colitis. In a large case-controlled study, there was a trend for long-term nonsteroidal anti-inflammatory consumption to be protective against CRC in patients with inflammatory bowel disease (IBD) (OR, 0.84). Sulfasalazine treatment over a 3-month period was shown to be protective (OR, 0.38), independently of disease activity. A longer-term study of sulfasalazine also revealed a relationship with treatment compliance, where 3% of compliant patients developed CRC compared with 31% of the noncompliers. Treatment with 5-ASA was associated with an increase in apoptosis, a decrease in proliferation of colorectal mucosa and has been shown to lower the rate of spontaneous mutation. In a retrospective, matched case-control study conducted in the UK, 102 patients with ulcerative colitis and CRC were matched with ulcerative colitis patients without CRC. Incidence was correlated to treatment protocols, family history and other risk factors. Mesalazine was the only treatment to be associated with a statistically significant reduction in the risk of developing cancer. Even after adjusting for variables, mesalazine at doses > 1.2 g / day reduced the risk of cancer by 81% (P = 0.006). Frequent visits to the clinician were also associated with a protective effect.

Abstract
Histological dysplasia is the cornerstone of colorectal cancer surveillance in ulcerative colitis (UC). Recently, pathologists have received unfavourable media attention concerning other cancer screening programmes. The aim of this study was to determine whether colonic biopsy specimens should be examined by gastrointestinal pathologists as opposed to generalists, by examining inter-observer variation between the two groups. Fifty-one coded slides showing varying degrees of dysplasia were mailed to seven gastrointestinal and six general histopathologists. Pathologists allocated each biopsy into one of four categories without the benefit of a clinical history or an opportunity to use the 'indefinite' category that is included in the Riddell classification. The responses were analysed using kappa statistics. The overall kappa statistic for gastrointestinal pathologists was 0.30 [95% confidence interval (CI)=0.26-0.34] and for general pathologists 0.28 (95% CI=0.23-0.32). Agreement was best for high-grade dysplasia (kappa of 0.54 and 0.61 for GI and general pathologists, respectively). There was total concordance of the 13 pathologists in only four of the 51 slides (7.8%) (95% CI=0.4-15.2%). It is concluded from these results that gastrointestinal pathologists are no better than generalists when grading dysplasia in UC and that agreement is poor in both groups. There is therefore no evidence that there would be any benefit in having specialist histopathology centres concentrating specifically on the interpretation of all surveillance colonoscopy biopsies from around the UK. It must be made clear to the public that surveillance and screening programmes carry a significant rate of histological error and that perfection cannot be expected or achieved with present methods.

Abstract
Screening has become central to the effective prevention of several diseases, but implementation suffers from difficulties with targeting and rates of compliance. Such issues are also complicated by the need to consider legal provisions regarding confidentiality of patients and other human rights issues. Screening has been an inexact science in relation to, e.g., faecal occult blood testing for colorectal cancer, false positive and false negative tests for HIV, and there have been inadequate quality controls in breast cancer screening programmes. The public need to be made aware of what the screening programmes really offer, balanced against the expectations they may have. There needs to be a clearer understanding of the nature of the contractual and other legal rights of patients/consumers as against providers. A positive screening test may carry adverse consequences as well as benefits. It could alert an insurance company to a risk and lead to additional weighting or even outright rejection for life insurance policies. Job prospects may also be affected for employees. The method of informing patients in relation to screening and screening failure has already been considered by the courts. Realistic information about both screening and treatment efficiency needs to be offered to patients so that they can have a real understanding of what can and cannot be achieved by current science. The development of understanding of the human genome makes the need for clearer legislation in this are more urgent.

Abstract
BACKGROUND The risk of colorectal cancer (CRC) in ulcerative colitis (UC) increases with extent and duration of disease. Identifying other risk factors would allow targeting of sub-groups at greatest risk, enabling more cost-effective surveillance. METHODS We conducted a case-control study comparing 102 cases of CRC in UC with matched controls. Odds ratios (OR) for cancer risk were estimated by conditional logistic regression. A multivariate model assessed the contribution of individual variables. RESULTS Regular 5-aminosalicylic acid (5-ASA) therapy reduces cancer risk by 75% (OR 0.25, 95% CI: 0.13-0.48, P < 0.00001). Adjusting for other variables, taking mesalazine regularly reduces risk by 81% (OR 0.19, 95% CI: 0.06-0.61, P=0.006) and visiting a hospital doctor more than twice a year also reduces risk (OR 0.16, 95% CI: 0.04-0.60, P=0.007). Considering variables independently, having a family history of sporadic CRC in any relative increases risk fivefold (OR 5.0, 95% CI: 1.10-22.82, P < 0.04). CONCLUSIONS CRC risk among UC patients can be reduced by regular therapy with 5-ASA medication. Colonoscopic surveillance may be best targeted on those unable to take 5-ASAs (e.g. due to allergy) and those with a positive family history of CRC.

Abstract
Achalasia is one of the earliest recognized gastroenterological conditions. However, several centuries after it was first described, it remains also among the least understood. One of the main reasons for this is the relative rarity of the disease, which has resulted in limited opportunities to conduct investigative research. Few epidemiological studies have been conducted to date, and their data suggest a worldwide incidence estimated at between 0.03-1.1/10(5)/yr. This review of the literature on the epidemiology of achalasia lends support to the idea that pooling of resources and collaboration at an international level is required, if any significant progress in the cause, treatment, and prevention of the disease is to be made.

Abstract
STUDY OBJECTIVE The assessment of the uptake of colorectal cancer screening offered in a workplace setting. DESIGN Employees were offered a free faecal occult blood test (Haemoccult). A repeat letter was sent two months later to non-responders. Those with positive tests were invited for colonoscopy. Compliance was measured according to age, sex, and occupational group and the effects of reinviting non-compliers investigated. SETTING Leicester General Hospital, a large university teaching hospital. PARTICIPANTS 990 employees aged 41 to 65 years. MAIN RESULTS Total compliance was 46% with women participating more than men (49% v 34%, chi 2 = 12.2, p < 0.001). The difference was mostly because of women aged 41 to 50 years complying more than their male counterparts (48% v 24%, chi 2 = 15.5, p < 0.0001). Participation was highest in clinical support staff (56%), nurses (52%), and clerical workers (46%). Uptake by doctors (26%) and managers (26%) was significantly lower than by clinical support staff and nurses (chi 2 > 5.5, p < 0.02). Remailing raised compliance slightly from 43.6% to 46.3%. Four employees (1%) had positive faecal occult blood tests but three were negative on repeat testing with dietary restrictions. CONCLUSIONS The government favours the development of health promotion programmes as stated in its document "Health at work in the NHS". The response in this study, showed methods to increase compliance must be developed if such programmes are to be successful. As uptake was similar to that in several community based programmes in general practice, workplace based programmes could offer a complementary method of delivering screening.
