Abstract
BACKGROUND People with Parkinson's disease (PD) have an increased risk of dementia, yet patients and clinicians frequently avoid talking about it due to associated stigma, and the perception that "nothing can be done about it". However, open conversations about PD dementia may allow people with the condition to access treatment and support, and may increase participation in research aimed at understanding PD dementia. OBJECTIVES To co-produce information resources for patients and healthcare professionals to improve conversations about PD dementia. METHODS We worked with people with PD, engagement experts, artists, and a PD charity to open up these conversations. 34 participants (16 PD; 6 PD dementia; 1 Parkinsonism, 11 caregivers) attended creative workshops to examine fears about PD dementia and develop information resources. 25 PD experts contributed to the resources. RESULTS While most people with PD (70%) and caregivers (81%) shared worries about cognitive changes prior to the workshops, only 38% and 30%, respectively, had raised these concerns with a healthcare professional. 91% of people with PD and 73% of caregivers agreed that PD clinicians should ask about cognitive changes routinely through direct questions and perform cognitive tests at clinic appointments. We used insights from the creative workshops, and input from a network of PD experts to co-develop two open-access resources: one for people with PD and their families, and one for healthcare professionals. CONCLUSION Using artistic and creative workshops, co-learning and striving for diverse voices, we co-produced relevant resources for a wider audience to improve conversations about PD dementia.

Abstract
As awareness on the impact of anthropogenic underwater noise on marine life grows, underwater noise measurement programs are needed to determine the current status of marine areas and monitor long-term trends. The Joint Monitoring Programme for Ambient Noise in the North Sea (JOMOPANS) collaborative project was funded by the EU Interreg to collect a unique dataset of underwater noise levels at 19 sites across the North Sea, spanning many different countries and covering the period from 2019 to 2020. The ambient noise from this dataset has been characterised and compared - setting a benchmark for future measurements in the North Sea area. By identifying clusters with similar sound characteristics in three broadband frequency bands (25-160 Hz, 0.2-1.6 kHz, and 2-10 kHz), geographical areas that are similarly affected by sound have been identified. The measured underwater sound levels show a persistent and spatially uniform correlation with wind speed at high frequencies (above 1 kHz) and a correlation with the distance from ships at mid and high frequencies (between 40 Hz and 4 kHz). Correlation with ocean current velocity at low frequencies (up to 200 Hz), which are susceptible to nonacoustic contamination by flow noise, was also evaluated. These correlations were evaluated and simplified linear scaling laws for wind and current speeds were derived. The presented dataset provides a baseline for underwater noise measurements in the North Sea and shows that spatial variability of the dominant sound sources must be considered to predict the impact of noise reduction measures.

Abstract
BACKGROUND There is significant unmet need for effective and efficiently delivered care for people with Parkinson's disease (PwP). We undertook a service improvement initiative to co-develop and implement a new care pathway, Home Based Care (HBC), based on supported self-management, remote monitoring and the ability to trigger a healthcare contact when needed. OBJECTIVE To evaluate feasibility, acceptability and safety of Home Based Care. METHODS We evaluated data from the first 100 patients on HBC for 6 months. Patient monitoring, performed at baseline and 6-monthly, comprised motor (MDS-UPDRS II and accelerometer), non-motor (NMSQ, PDSS-2, HADS) and quality of life (PDQ) measures. Care quality was audited against Parkinson's UK national audit standards. Process measures captured feasibility. Acceptability was assessed using a mixed-methods approach comprising questionnaires and semi-structured interviews. RESULTS Between October 2019 and January 2021, 108 PwP were enrolled onto HBC, with data from 100 being available at 6 months. Over 90% of all questionnaires were returned, 97% were complete or had < 3 missing items. Reporting and communications occurred within agreed timeframes. Compared with baseline, after 6m on HBC, PD symptoms were stable; more PwP felt listened to (90% vs. 79%) and able to seek help (79% vs. 68%). HBC met 93% of national audit criteria. Key themes from the interviews included autonomy and empowerment. CONCLUSIONS We have demonstrated acceptability, feasibility and safety of our novel remotely delivered Parkinson's care pathway. Ensuring scalability will widen its reach and realize its benefits for underserved communities, enabling formal comparisons with standard care and cost-effectiveness evaluation.

Abstract
Germline pathogenic variants in the DNA mismatch repair (MMR) genes (Lynch syndrome) predispose to colorectal (CRC) and endometrial (EC) cancer. Lynch syndrome specific tumor features were evaluated for their ability to support the ACMG/InSiGHT framework in classifying variants of uncertain clinical significance (VUS) in the MMR genes. Twenty-eight CRC or EC tumors from 25 VUS carriers (6xMLH1, 9xMSH2, 6xMSH6, 4xPMS2), underwent targeted tumor sequencing for the presence of microsatellite instability/MMR-deficiency (MSI-H/dMMR) status and identification of a somatic MMR mutation (second hit). Immunohistochemical testing for the presence of dMMR crypts/glands in normal tissue was also performed. The ACMG/InSiGHT framework reclassified 7/25 (28%) VUS to likely pathogenic (LP), three (12%) to benign/likely benign, and 15 (60%) VUS remained unchanged. For the seven re-classified LP variants comprising nine tumors, tumor sequencing confirmed MSI-H/dMMR (8/9, 88.9%) and a second hit (7/9, 77.8%). Of these LP reclassified variants where normal tissue was available, the presence of a dMMR crypt/gland was found in 2/4 (50%). Furthermore, a dMMR endometrial gland in a carrier of an MSH2 exon 1-6 duplication provides further support for an upgrade of this VUS to LP. Our study confirmed that identifying these Lynch syndrome features can improve MMR variant classification, enabling optimal clinical care.

Abstract
This study explores the implementation and impact of an evidence-based client-driven program, CAPABLE (Community Aging in Place Advancing Better Living for Elders), during the COVID-19 pandemic. The study reviews outcomes related to client engagement and retainment, client-directed goals, therapeutic intervention, home modifications, and functional outcomes of older adult participants. The CAPABLE program addresses basic and instrumental activities of daily living, medication use, pain, mobility, fall prevention, and environmental modifications within the home. The services were provided by an interprofessional team which included an occupational therapist, a registered nurse, and home contractor professional. The study team utilized descriptive, paired t test, and correlational analyses to evaluate the CAPABLE programs' influence on the functional outcomes of older adults living within the city of St. Louis, during the COVID-19 pandemic. This study identified significant improvement in instrumental activities of daily living (IADLs) independence, readiness to change, self-reported health status, and depressive symptoms, and 11 significant correlations were found between age, implementation expenses, and functional outcomes.

Abstract
Telehealth services enable individuals to participate in meaningful occupations; however, the evidence on this topic has not been synthesized in older adult populations. This scoping review synthesized the evidence on interventions delivered through telehealth (and the mode of delivery) in occupational therapy for older adult populations. A search for studies on occupational therapy, older adults, and telehealth was performed in six research databases, and identified 536 articles. Four reviewers independently screened the titles and abstracts; and reviewed eligible full text. Ten articles were extracted into a table and summarized through narrative format. The studies focused on performance-based intervention (60%), cognition (10%), health (10%), occupation (10%), and the environment (10%) in older adult populations (N = 1 - 208); including those with Alzheimer's disease, chronic pain, cancer, and stroke. The interventions were delivered through electronic audio-visual platforms (e.g., zoom) (80%) and teleconference platforms (e.g., phone calls) (20%).

Abstract
BACKGROUND MLH1 epimutation is characterised by constitutional monoallelic MLH1 promoter hypermethylation, which can cause colorectal cancer (CRC). Tumour molecular profiles of MLH1 epimutation CRCs were used to classify germline MLH1 promoter variants of uncertain significance and MLH1 methylated early-onset CRCs (EOCRCs). Genome-wide DNA methylation and somatic mutational profiles of tumours from two germline MLH1: c.-11C > T and one MLH1: c.-[28A > G; 7C > T] carriers and three MLH1 methylated EOCRCs (< 45 years) were compared with 38 reference CRCs. Methylation-sensitive droplet digital PCR (ddPCR) was used to detect mosaic MLH1 methylation in blood, normal mucosa and buccal DNA. RESULTS Genome-wide methylation-based Consensus Clustering identified four clusters where the tumour methylation profiles of germline MLH1: c.-11C > T carriers and MLH1 methylated EOCRCs clustered with the constitutional MLH1 epimutation CRCs but not with the sporadic MLH1 methylated CRCs. Furthermore, monoallelic MLH1 methylation and APC promoter hypermethylation in tumour were observed in both MLH1 epimutation and germline MLH1: c.-11C > T carriers and MLH1 methylated EOCRCs. Mosaic constitutional MLH1 methylation in MLH1: c.-11C > T carriers and 1 of 3 MLH1 methylated EOCRCs was identified by methylation-sensitive ddPCR. CONCLUSIONS Mosaic MLH1 epimutation underlies the CRC aetiology in MLH1: c.-11C > T germline carriers and a subset of MLH1 methylated EOCRCs. Tumour profiling and ultra-sensitive ddPCR methylation testing can be used to identify mosaic MLH1 epimutation carriers.

Abstract
Routine screening of tumors for DNA mismatch repair (MMR) deficiency (dMMR) in colorectal (CRC), endometrial (EC) and sebaceous skin (SST) tumors leads to a significant proportion of unresolved cases classified as suspected Lynch syndrome (SLS). SLS cases (n = 135) were recruited from Family Cancer Clinics across Australia and New Zealand. Targeted panel sequencing was performed on tumor (n = 137; 80×CRCs, 33×ECs and 24xSSTs) and matched blood-derived DNA to assess for microsatellite instability status, tumor mutation burden, COSMIC tumor mutational signatures and to identify germline and somatic MMR gene variants. MMR immunohistochemistry (IHC) and MLH1 promoter methylation were repeated. In total, 86.9% of the 137 SLS tumors could be resolved into established subtypes. For 22.6% of these resolved SLS cases, primary MLH1 epimutations (2.2%) as well as previously undetected germline MMR pathogenic variants (1.5%), tumor MLH1 methylation (13.1%) or false positive dMMR IHC (5.8%) results were identified. Double somatic MMR gene mutations were the major cause of dMMR identified across each tumor type (73.9% of resolved cases, 64.2% overall, 70% of CRC, 45.5% of ECs and 70.8% of SSTs). The unresolved SLS tumors (13.1%) comprised tumors with only a single somatic (7.3%) or no somatic (5.8%) MMR gene mutations. A tumor-focused testing approach reclassified 86.9% of SLS into Lynch syndrome, sporadic dMMR or MMR-proficient cases. These findings support the incorporation of tumor sequencing and alternate MLH1 methylation assays into clinical diagnostics to reduce the number of SLS patients and provide more appropriate surveillance and screening recommendations.

Abstract
Background Antenatal pelvic floor muscle exercises (PFME) in women without prior urinary incontinence (UI) are effective in reducing postnatal UI; however, UK midwives often do not provide advice and information to women on undertaking PFME, with evidence that among women who do receive advice, many do not perform PFME. Methods The primary aim of this feasibility and pilot cluster randomised controlled trial is to provide a potential assessment of the feasibility of undertaking a future definitive trial of a midwifery-led antenatal intervention to support women to perform PFME in pregnancy and reduce UI postnatally. Community midwifery teams in participating NHS sites comprise trial clusters (n = 17). Midwives in teams randomised to the intervention will be trained on how to teach PFME to women and how to support them in undertaking PFME in pregnancy. Women whose community midwifery teams are allocated to control will receive standard antenatal care only. All pregnant women who give birth over a pre-selected sample month who receive antenatal care from participating community midwifery teams (clusters) will be sent a questionnaire at 10–12 weeks postpartum (around 1400–1500 women). Process evaluation data will include interviews with midwives to assess if the intervention could be implemented as planned. Interviews with women in both trial arms will explore their experiences of support from midwives to perform PFME during pregnancy. Data will be stored securely at the Universities of Birmingham and Exeter. Results will be disseminated through publications aimed at maternity service users, clinicians, and academics and inform a potential definitive trial of effectiveness. The West Midlands–Edgbaston Research Ethics Committee approved the study protocol. Discussion Trial outcomes will determine if criteria to progress to a definitive cluster trial are met. These include women’s questionnaire return rates, prevalence of UI, and other health outcomes as reported by women at 10–12 weeks postpartum. Progress to a definitive trial however is likely to be prevented in the UK context by new perinatal pelvic health service, although this may be possible elsewhere.

Abstract
BackgroundCurrent care pathways for people with Parkinson’s (PwP) are not tailored to need. In line with the NHS Long Term Plan, together with PwP, we have co-developed, piloted and evaluated an innovative care pathway, ‘Home Based Care (HBC)’, based on supported self-management, triggered contacts and digitally-enabled remote monitoring.MethodEvaluation was performed at baseline and 6-monthly of motor (UPDRS II and accelerometer) and non-motor (NMSQ, PDSS2, HADS) symptoms, acceptability and self-management efficacy. Care was audited using Parkinson’s UK national audit standards. Process measures captured feasibility.ResultsData are available for 93 patients at baseline and 38 at 6m. Compared with baseline, after 6m on HBC, fewer PwP had uncontrolled bradykinesia (55.3% vs 63.4%), severe non-motor symptom burden (32.4% vs 50.6%), depression (2.9% vs 15.9%) and anxiety (17.1% vs 23.2%); median UPDRS II improved from 12.0 to 9.0; PwP felt more involved in care (70% vs 42%), listened to (72% vs 48%) and treated as an individual (81% vs 58%), as well as having increased PD understanding (57% vs 38%) and ability to self- manage (45% vs 34%). HBC met 93% of national audit criteria.ConclusionsWe have demonstrated acceptability, feasibility and effectiveness of our novel Parkinson’s care pathway.e.king6@nhs.net|NIHR Bursary

Abstract
Healthcare for people with Parkinson’s (PwP) can vary across the UK. With the prediction that numbers will increase by a fifth by 2025, the Parkinson’s specialist team in Plymouth recognised an opportunity to meet the challenge with a service re-design that incorporated patient initiated contact and digital technology.Following a series of workshops facilitated by healthcare design engineers, and attended by PwP, their family, Parkinson’s practitioners, and digital health representatives, various supportive and educational materials were devised to support patient self-management supported by home based monitoring.The main structure and associated materials of the pathway incorporated 3 main themes:Education and support (which includes an initial teaching session, information booklets, symptom tracking cards, and an online social media group for peer support);Clear information on how to initiate a healthcare contact via a dedicated email and telephone hotline;Motor and non-motor symptoms monitored from home via the Parkinson’s KinetigraphTM (PKG) watch and regular completion of validated questionnaires.The first phase of this Health Foundation Innovation project was implemented in Oct 2019 with 10 PwP from Plymouth taking part. A wider roll out of the pathway involving people in East Cornwall, West Devon and Plymouth is taking place in 2020, involving 150 patients. Embedded processes for evaluation and feedback inform continued development and refinement of the pathway.camille.carroll@plymouth.ac.uk

Abstract
INTRODUCTION The evolution of technology within healthcare is continuing at a rapid rate. Touchless technologies (i.e. those involving gestures and voice commands) are rapidly being integrated into daily life. The aim of this study was to investigate the potential role for such technologies within diagnostic radiography. METHODS An online survey was developed, piloted and deployed using SurveyMonkey as part of an online radiology congress. Eligible respondents were radiographers or radiologic technologists, including students. The survey covered ten themes relating to the potential role of touchless technologies within diagnostic radiography. Results were analysed using descriptive and inferential statistics. RESULTS 155 people completed the questionnaire. 100 (64.9%) were women and clinical experience ranged from 13.5 (0-40) years. The majority, 54 (35.1%), had a Bachelor's degree with respondents being from 23 different countries (five continents). 34 (21.9%) respondents did not personally own nor intended to purchase touchless technologies. 89 (84.8%) respondents saw themselves using touchless technologies, if available on current imaging equipment. 25 (16.0%) respondents reported that they currently have access to touchless technologies within their workplace. 88 (81.5%) and 67 (65.0%) respondents reported that they saw voice and gesture controls as being key in improving exam efficiency. CONCLUSION Participants clearly perceived a role for touchless technologies within diagnostic radiography. Access to such technologies is not yet widely available within X-ray rooms. Voice activated technologies appear more appealing that gesture-based aids. The primary role for such technologies was defined by participants as focusing on improving examination efficiency. IMPLICATIONS FOR PRACTICE Touchless technologies have been identified and as important and potentially useful in diagnostic radiography. Collaboration between healthcare institutions, industry and academia is required to design and successfully implement these technologies into practice.

Abstract
Dairy cows housed in tiestalls are restricted to one space; therefore, this space should be designed to accommodate all the activities cows need to perform. Lying is a very important behavior for dairy cows as well as a critical measure in the assessment of stall designs, to ensure that the cows' needs for resting space are met. The objective of this study was to determine if increasing tiestall width alters the lying behavior of lactating dairy cows. Two treatments were compared: the current recommendation (139 cm) and a double stall (284 cm). Sixteen cows were blocked by parity and lactation stage, then randomly allocated to a treatment and a stall within 1 of 2 rows in the research barn, for 6 wk. The average stall length was 188 cm. Leg-mounted accelerometers were used to record lying behaviors. Cows were video-recorded 24 h/wk using surveillance cameras positioned above the stalls. Video data from wk 1, 3, and 6 were extracted at a rate of 1 image/min and analyzed by a trained observer to assess the position and the location of the cow's body, head, and limbs during the lying hours. Lying behaviors and frequency of each position and location were analyzed in SAS (SAS Institute Inc., Cary, NC) using a mixed model in which treatment, block, and week were included as fixed factors, and cow and row as random factors. Multiple comparisons were adjusted using the Scheffé method. Results indicate that cows in double stalls fully extended their hindlimbs more often than single stall cows (21.7 vs. 7.6% of lying time). Cows in double stalls also intruded in the neighboring stalls with their hindlimbs less often (1.3 vs. 14.7% of lying time), instead positioning them inside their own stall more often (92.7 vs. 84.6% of lying time). Use of the second stall in the double stall group totaled 11.6, 5.1, 33.8, and 18.0% of lying time, respectively, for the head, front legs, hind legs, and body. Total lying time was not statistically different between double (716 min/d) and single stall (671 min/d) groups. Contacts with stall hardware during lying-down movements were also less frequent in double stalls (43.1 vs. 77.1% of lying events) compared with single stalls. These results suggest that dairy cows housed in double stalls modified their resting habits and used the extra space made available to them. Increasing stall width beyond the current recommendation is likely to benefit the cows by improving their ability to rest.

Abstract
QUESTION What strategies can clinical partners and universities implement to enhance physiotherapy student engagement in non-metropolitan clinical placements? DESIGN Mixed-method research design combining focus groups and survey. PARTICIPANTS First-year physiotherapy students from one university at the commencement of their course (n=26); third-year and fourth-year students who had completed a non-metropolitan placement (n=39 survey, n=25 focus group); and clinical educators from three non-metropolitan clinical sites (n=15). INTERVENTION The cohort of first-year physiotherapy students was surveyed to establish their perceptions regarding non-metropolitan clinical education placements. A survey and four focus groups were conducted with third-year and fourth-year students after they had attended non-metropolitan clinical placements, to explore recent experiences. Two focus groups were conducted with clinical educators regarding student engagement at non-metropolitan placements. Quantitative data were summarised with descriptive statistics. Qualitative data were analysed using thematic analysis, synthesising the perspectives of students and clinical educators. RESULTS At the commencement of their physiotherapy course, interest in undertaking a non-metropolitan clinical placement was higher for students with a non-metropolitan upbringing. Concerns about attending non-metropolitan sites included finances, change in living situation, and perceived inferior quality of clinical education. After completing a non-metropolitan placement, four themes were identified in an analysis of student and educator perceptions: individual factors, clinical experience, logistical challenges and strategies for success. CONCLUSION Strategies that were perceived to enhance student engagement in non-metropolitan placements included: tailoring preparation for students, paired rather than individual placements, and near-peer presentations for physiotherapy students prior to undertaking non-metropolitan placements. Dedicated clinical coordinator positions at non-metropolitan sites and assistance in accessing affordable accommodation are likely to positively influence the student experience.

Abstract
OBJECTIVES To describe trends in the incidence and prevalence of diabetic retinopathy (DR) in the UK by diabetes type, age, sex, ethnicity, deprivation, region and calendar year. DESIGN Cohort study using the Clinical Practice Research Datalink (CPRD). SETTING UK primary care. PARTICIPANTS 7.7 million patients ≥12 contributing to the CPRD from 2004 to 2014. PRIMARY AND SECONDARY OUTCOME MEASURES Age-standardised prevalence and incidence of diabetes, DR and severe DR (requiring photocoagulation) by calendar year and population subgroup. Relative risk of developing DR and severe DR by population subgroup. RESULTS The prevalence of DR was 48.4% in the population type 1 diabetes mellitus (T1DM) (14 846/30 657) and 28.3% (95 807/338 390) in the population with type 2 diabetes mellitus (T2DM). Prevalence of DR remained stable in people with T2DM and decreased in people with T1DM. Screening for DR increased over time for patients with T2DM and remained static for patients with T1DM Incidence of DR increased in parallel with the incidence of T2DM in both diabetic populations. Among patients with T2DM, relative risk of DR varied significantly by region, was increased for older age groups and in men compared with women, with risk of severe DR increased in South Asian groups and more deprived groups. Relative risk of DR for patients with T1DM varied by age and region, but not by gender, ethnic group or deprivation. CONCLUSIONS This is the largest study to date examining the burden of DR in the UK. Regional disparities in incidence may relate to differences in screening delivery and disease ascertainment. Evidence that deprivation and ethnicity are associated with a higher risk of severe DR highlights a significant potential health inequality. Findings from this study will have implications for professionals working in the diabetes and sight loss sectors, particularly to inform approaches for diagnosis of retinopathy and campaigning to better tackle the disease for at risk groups.

Abstract
Background Cytomegalovirus (CMV) is a highly prevalent herpesvirus, which maintains lifelong latency and places a significant burden on host immunity. Infection is associated with increased rates of vascular disease and overall mortality in the elderly and there is an urgent need for improved understanding of the viral-host balance during ageing. CMV is extremely difficult to detect in healthy donors, however, using droplet digital PCR of DNA from peripheral blood monocytes, we obtained an absolute quantification of viral load in 44 healthy donors across a range of ages. Results Viral DNA was detected in 24 % (9/37) of donors below the age of 70 but was found in all individuals above this age. Furthermore, the mean CMV load was only 8.6 copies per 10,000 monocytes until approximately 70 years of age when it increased by almost 30 fold to 249 copies in older individuals (p < 0.0001). CMV was found within classical CD14+ monocytes and was not detectable within the CD14-CD16+ subset. The titre of CMV-specific IgG increased inexorably with age indicating that loss of humoral immunity is not a determinant of the increased viral load. In contrast, although cellular immunity to the structural late protein pp65 increased with age, the T cell response to the immediate early protein IE1 decreased in older donors. Conclusion These data reveal that effective control of CMV is impaired during healthy ageing, most probably due to loss of cellular control of early viral reactivation. This information will be of value in guiding efforts to reduce CMV-associated health complications in the elderly.

Abstract
OBJECTIVE To implement the Individual Placement and Support (IPS) approach at 4 locations in regional New South Wales, Australia. Outcomes attained were compared with a national non-IPS program and with international trials of IPS within and outside the United States. METHODS Four IPS programs were established through formal partnerships between mental health services and disability employment services. Ninety-five mental health service clients commenced employment assistance and were tracked for a minimum of 12 months. RESULTS Two sites achieved good fidelity to IPS principles, and 2 sites achieved fair fidelity. IPS clients had 3.5 times greater odds of attaining 13 weeks' employment than those receiving assistance in the national network of disability employment services. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE Implementing IPS is challenging in the Australian service delivery context. Factors other than program fidelity appear to contribute to excellent employment outcomes. Further research is needed to identify these factors.

Abstract
Kidney transplant and liver transplant are the treatments of choice for patients with end-stage renal disease and end-stage liver disease, respectively. Pancreas transplant is most commonly performed along with kidney transplant in diabetic end-stage renal disease patients. Despite a steady increase in the numbers of kidney and liver transplants performed each year in the United States, a significant shortage of kidneys and livers available for transplant remains. Organ allocation is the process the Organ Procurement and Transplantation Network (OPTN) uses to determine which candidates are offered which deceased donor organs. OPTN is charged with ensuring the effectiveness, efficiency and equity of organ sharing in the national system of organ allocation. The policy has changed incrementally over time in efforts to optimize allocation to meet these often competing goals. This review describes the history, current status and future direction of policies regarding the allocation of abdominal organs for transplant, namely the kidney, liver and pancreas, in the United States.

Abstract
Patients with hepatocellular carcinoma (HCC) within Milan criteria receive priority on the liver transplant waiting list (WL) and compete with non-HCC patients. Dropout from the WL is an indirect measure of transplant access. Competing risks (CR) evaluation of dropout for HCC and non-HCC patients has not previously been reported. Patients listed between 16 March 2005 and 30 June 2008 were included. Probability of dropout was estimated using a CR technique as well as a Cox model for time to dropout. Overall, non-HCC patients had a higher dropout rate from the WL than HCC patients (p < 0.0001). This was reproducible throughout all regions. In Cox regression, tumor size, model for end-stage liver disease (MELD) score and alpha fetoprotein (AFP) were associated with increased dropout risk. Multivariable analysis with CR showed that MELD score and AFP, were most influential in predicting dropout for HCC patients. The index of concordance for predicting dropout with the CR was 0.70. HCC patients appear to be advantaged in the current allocation scheme based on lower dropout rates without regard to geography. A continuous score incorporating MELD, AFP and tumor size may help to prioritize HCC patients to better equate dropout rates with non-HCC patients and equalize access.

Abstract
OBJECTIVE To determine the accuracy, acceptability and cost-effectiveness of polymerase chain reaction (PCR) and optical immunoassay (OIA) rapid tests for maternal group B streptococcal (GBS) colonisation at labour. DESIGN A test accuracy study was used to determine the accuracy of rapid tests for GBS colonisation of women in labour. Acceptability of testing to participants was evaluated through a questionnaire administered after delivery, and acceptability to staff through focus groups. A decision-analytic model was constructed to assess the cost-effectiveness of various screening strategies. SETTING Two large obstetric units in the UK. PARTICIPANTS Women booked for delivery at the participating units other than those electing for a Caesarean delivery. INTERVENTIONS Vaginal and rectal swabs were obtained at the onset of labour and the results of vaginal and rectal PCR and OIA (index) tests were compared with the reference standard of enriched culture of combined vaginal and rectal swabs. MAIN OUTCOME MEASURES The accuracy of the index tests, the relative accuracies of tests on vaginal and rectal swabs and whether test accuracy varied according to the presence or absence of maternal risk factors. RESULTS PCR was significantly more accurate than OIA for the detection of maternal GBS colonisation. Combined vaginal or rectal swab index tests were more sensitive than either test considered individually [combined swab sensitivity for PCR 84% (95% CI 79-88%); vaginal swab 58% (52-64%); rectal swab 71% (66-76%)]. The highest sensitivity for PCR came at the cost of lower specificity [combined specificity 87% (95% CI 85-89%); vaginal swab 92% (90-94%); rectal swab 92% (90-93%)]. The sensitivity and specificity of rapid tests varied according to the presence or absence of maternal risk factors, but not consistently. PCR results were determinants of neonatal GBS colonisation, but maternal risk factors were not. Overall levels of acceptability for rapid testing amongst participants were high. Vaginal swabs were more acceptable than rectal swabs. South Asian women were least likely to have participated in the study and were less happy with the sampling procedure and with the prospect of rapid testing as part of routine care. Midwives were generally positive towards rapid testing but had concerns that it might lead to overtreatment and unnecessary interference in births. Modelling analysis revealed that the most cost-effective strategy was to provide routine intravenous antibiotic prophylaxis (IAP) to all women without screening. Removing this strategy, which is unlikely to be acceptable to most women and midwives, resulted in screening, based on a culture test at 35-37 weeks' gestation, with the provision of antibiotics to all women who screened positive being most cost-effective, assuming that all women in premature labour would receive IAP. The results were sensitive to very small increases in costs and changes in other assumptions. Screening using a rapid test was not cost-effective based on its current sensitivity, specificity and cost. CONCLUSIONS Neither rapid test was sufficiently accurate to recommend it for routine use in clinical practice. IAP directed by screening with enriched culture at 35-37 weeks' gestation is likely to be the most acceptable cost-effective strategy, although it is premature to suggest the implementation of this strategy at present.

Abstract
BACKGROUND & AIMS MUTYH-associated polyposis (MAP) is an autosomal recessive disorder caused by mutations in the MUTYH gene. Patients with MAP are at extremely high risk of colorectal cancer, but the risks of colorectal and other cancers in heterozygous carriers of a single MUTYH mutation are uncertain. We performed a retrospective study of cancer incidence and causes of death among obligate MUTYH heterozygote individuals. METHODS MAP index cases were identified from polyposis registers in Germany, The Netherlands, and the United Kingdom. Cancer incidence, cancer mortality, and all-cause mortality data were collected from 347 parents of unrelated MAP index cases and the spouses of 3 index cases who were also found to be heterozygous for single MUTYH mutations. These data were compared with appropriate national sex-, age-, and period-specific population data to obtain standardized mortality ratios (SMR) and standardized incidence ratios (SIR). RESULTS There was a 2-fold increase in the incidence of colorectal cancer among parents of MAP cases, compared with the general population (SIR, 2.12; 95% confidence interval [CI]: 1.30-3.28). Their colorectal cancer mortality was not increased significantly (SMR, 1.02; 95% CI: 0.41-2.10) nor was overall cancer risk (SIR, 0.92; 95% CI: 0.70-1.18), cancer mortality (SMR, 1.12; 95% CI: 0.83-1.48), or overall mortality (SMR, 0.94; 95% CI: 0.80-1.08). CONCLUSIONS The risk of colorectal cancer in heterozygous carriers of single MUTYH mutations who are relatives of patients with MAP is comparable with that of first-degree relatives of patients with sporadic colorectal cancer. Screening measures should be based on this modest increase in risk.

Abstract
AIM OF THE STUDY Genista tenera is a plant endemic to the island of Madeira and is used in folk medicine to control diabetes. In the present work we evaluate the antihyperglycaemic activity of its n-butanol extract and determine its chromatographic profile. In addition, this extract, the ethyl acetate and diethyl ether plant extracts were studied in order to assess the plant antioxidant and acetylcholinesterase inhibitory activities, as well as its cyto- and genotoxicities. MATERIALS AND METHODS HPLC-DAD-ESI-MS was used to analyze the flavonoid profile of the n-butanol extract. The antihyperglycaemic activity of this extract was performed over streptozotocin induced diabetic Wistar rats (200 mg/kg, bw/day), for 15 days. Antioxidant activity (DPPH assay) and acetylcholinesterase inhibitory effect (Ellman method) were also performed. Acute cytotoxicity and genotoxicity were assessed by proliferative index quantification and the short-term chromosomal aberration technique, after exposure of lymphocytes to the extracts. RESULTS AND CONCLUSIONS The n-butanol extract, where 21 monoglycosyl and 12 diglycosyl flavonoids were detected, significantly lowered blood glucose levels, bringing them to normal values after 15 days of treatment. The best radical scavenging activity was observed for the ethyl acetate extract (48.7% at 139.1 microg/mL), which was also the most effective one at the minimal concentration tested. The highest acetylcholinesterase inhibitory activity (77.0% at 70.0 microg/mL) was also obtained with the ethyl acetate extract. In vitro toxicity studies showed no evidence for acute cytotoxicity or genotoxicity. This is the first report on antidiabetic activity of genus Genista.

Abstract
A decade of empirical work in brain imaging, genomics, and other areas of research has yielded new knowledge about the frequency of incidental findings, investigator responsibility, and risks and benefits of disclosure. Straightforward guidance for handling such findings of possible clinical significance, however, has been elusive. In early work focusing on imaging studies of the brain, we suggested that investigators and institutional review boards must anticipate and articulate plans for handling incidental findings. Here we provide a detailed analysis of different approaches to the problem and evaluate their merits in the context of the goals and setting of the research and the involvement of neurologists, radiologists, and other physicians. Protecting subject welfare and privacy, as well as ensuring scientific integrity, are the highest priorities in making choices about how to handle incidental findings. Forethought and clarity will enable these goals without overburdening research conducted within or outside the medical setting.

Abstract
BACKGROUND Since the authors' report on the lateral approach to laparoscopic colon resection (LCR), medial-to-lateral (M-L) segmental resection has continued to evolve. This report analyzes their learning curve experience with a standardized three-trocar M-L technique, which demonstrates the influence of operative volume on proficiency and outcome. METHODS From January 1999 to December 2004, 100 consecutive patients underwent a standardized three-trocar M-L segmental LCR. Patient demographics, indications for surgery, operative proficiency (time), and outcome (i.e., blood loss, conversion to open surgery, length of hospital stay, morbidity, and mortality) were recorded. A learning curve analysis was performed using a t-test and analysis of variance (ANOVA). RESULTS The 100 M-L LCRs included sigmoid (55%), right (34%), left (6%), and transverse (5%) approaches. Overall learning curve proficiency was influenced by increasing operative experience (p = 0.02). However, significant and consistent improvement in the learning curve occurred only after 38 LCRs (p < 0.008). Notably, all conversions to open surgery (3%) occurred during the early learning curve. Similarly, early LCR patients experienced greater morbidity (mean, 21% vs 12%) and mortality (mean, 5% vs 2%) than their later counterparts. CONCLUSION To obtain optimum proficiency in performing LCR, a minimum of 38 M-L procedures is required. Operative and patient outcomes improve beyond the early learning curve.
