Abstract
INTRODUCTION Canadian Armed Forces (CAF) members must complete an annual fitness evaluation. Members with a total hip arthroplasty (THA) may be at risk of injury during these strenuous tests. To inform CAF policy, we sought expert consensus on the safety of fitness testing for members with a THA. METHODS We conducted a three-round Delphi study with a panel of hip arthroplasty experts to determine the safety of CAF operational fitness evaluations for members with a THA. The experts evaluated videos of the 10 individual tasks included in the evaluations. RESULTS All individual tasks were judged to be safe by consensus. One task, which involves digging with a shovel, was considered safe provided that participants avoid deep hip flexion. The nine other tasks were judged to be safe without modifications or interventions. The experts also supported a policy recommendation that would allow members to perform military fitness evaluations if they (1) have a primary THA, (2) had no episodes of instability, (3) are at least 12 months postoperatively and (4) have been cleared by an orthopaedic surgeon and a physiatrist/physiotherapist. CONCLUSION A panel of arthroplasty experts concluded, based on video analysis, that CAF fitness evaluations are generally safe for members with a THA.

Abstract
BACKGROUND We aimed to determine the knowledge, training, practices and attitudes of obstetric anaesthetic practitioners with regard to failed neuraxial anaesthesia for caesarean delivery. METHOD We performed a contemporaneous and representative survey in an innovative fashion. We conducted an international cross-sectional study of obstetric anaesthetic practitioners at the Annual Scientific Meeting of the Obstetric Anaesthetists' Association (OAA 2021). Validated survey questions were collected in real time using an audience response system. RESULTS Of the 426 participants who logged into the survey system, 356 provided responses (4173 responses to 13 questions, across all grades/seniority of practitioner). The number of responses to questions ranged from 81% to 61%. Survey responses suggest that it is routine for respondents to inform patients about the difference between pain and expected intra-operative sensations, (320/327, 97.9%) but less routine to inform patients of the risk of intra-operative pain (204/260, 78.5%), or the possibility of conversion to general anaesthesia. (290/309 93.8%). Only 30% of respondents reported the use of written guidelines for follow-up of patients who experience intra-operative pain under neuraxial anaesthesia, and only 23% reported formal training in management of intra-operative pain under neuraxial anaesthesia. Respondents felt that inadequate block duration, prolonged surgery, and patient anxiety were contributory factors to failed anaesthesia, and the contributory factors differed between grade/seniority of practitioner. Modalities used to test a block were cold, motor block and light touch, with approximately 65% of respondents routinely using three modalities. CONCLUSIONS Our study survey found that the consent process may not always be adequately comprehensive, and that standardised documentation and testing of the block and focused training may be beneficial to prevent patient dissatisfaction and the chance of litigation.

Abstract
Most aspects of in-vitro fertilisation (IVF) have changed dramatically since introduction, but embryo transfer (ET) technique remains largely unaltered. We aimed to determine whether four-dimensional ultrasound guided embryo transfers (4D UGET) could improve pregnancy rates when compared with clinical touch technique (CTT). This was a single centre open labelled randomised controlled trial in a tertiary fertility centre in the UK. 320 women were randomised on the day of single ET. The primary outcome was clinical pregnancy rate (CPR), secondary outcomes included live birth rate (LBR), biochemical pregnancy rate (BPR), miscarriage, pregnancy of unknown location (PUL) and ectopic pregnancy. 4D-UGET resulted in significantly higher CPR [50% vs 36% p = 0.02, OR 1.78 (1.12-2.84)] and LBR [41% vs 28%, p = 0.02, OR 1.77 (1.09-2.87)] when compared to CTT technique. Miscarriage (p = 0.49), PUL (p = 0.14) and ectopic pregnancy (p = 0.96) were similar between the two groups. LBR, from this trial, are significantly higher than the current UK average (41% vs 24%). 4D UGET allows for superior imaging of the uterine cavity, whilst tailoring the embryo deposition point specifically to the patient. Further RCTs are required to determine if these results can be replicated in other units and whether 4D UGET is superior to 2D UGET.

Abstract
Type 2 diabetes (T2D) is associated with compromised identity of insulin-producing pancreatic islet β cells, characterized by inappropriate production of other islet cell-enriched hormones. Here, we examined how hormone misexpression was influenced by the MAFA and MAFB transcription factors, closely related proteins that maintain islet cell function. Mice specifically lacking MafA in β cells demonstrated broad, population-wide changes in hormone gene expression with an overall gene signature closely resembling islet gastrin+ (Gast+) cells generated under conditions of chronic hyperglycemia and obesity. A human β cell line deficient in MAFB, but not one lacking MAFA, also produced a GAST+ gene expression pattern. In addition, GAST was detected in human T2D β cells with low levels of MAFB. Moreover, evidence is provided that human MAFB can directly repress GAST gene transcription. These results support a potentially novel, species-specific role for MafA and MAFB in maintaining adult mouse and human β cell identity, respectively. Here, we discuss the possibility that induction of Gast/GAST and other non-β cell hormones, by reduction in the levels of these transcription factors, represents a dysfunctional β cell signature.

Abstract
BACKGROUND Anaesthetists are crucial members of the maternity unit team, providing peri-operative analgesia and anaesthesia, and supporting the delivery of medical care to high-risk women. The effective contribution from obstetric anaesthetists to safety in maternity units depends on how anaesthesia services are organised and resourced. There is a lack of information on how obstetric anaesthetic care is resourced in the UK. METHODS The Obstetric Anaesthetists' Association surveyed UK clinical leads for their hospital's obstetric anaesthetic service and examined compliance with national recommendations. RESULTS There were 153 responses by lead obstetric anaesthetists from 184 maternity units in the UK (83%). The number of consultants per 1000 deliveries was 2.2 [1.6-2.7] (median [IQR]). In 20% of units, there was a dedicated on-call rota (on-call only for obstetric anaesthesia), whilst the remainder had a 'combined' on-call rota (on-call for other clinical areas in addition to obstetrics). Multidisciplinary ward rounds were held in 83% of units. Twenty-five (16%) units reported having no regular multidisciplinary ward rounds, of which nine (6%) did not have any multidisciplinary ward rounds. Planned operating lists for elective caesarean sections were provided in 77% of units. CONCLUSIONS In the largest survey of obstetric anaesthesia workload to be reported for any health system, we found significant disparities between obstetric anaesthesia service provision and current national recommendations for areas including consultant staffing, support for elective caesarean section lists, antenatal anaesthetic clinics, and consultant support for service development. Wide national variation in service provision was identified.

Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
A woman who experiences pain during caesarean section under neuraxial anaesthesia is at risk of adverse psychological sequelae. Litigation arising from pain during caesarean section under neuraxial anaesthesia has replaced accidental awareness under general anaesthesia as the most common successful medicolegal claim against obstetric anaesthetists. Generic guidelines on caesarean section exist, but they do not provide specific recommendations for this area of anaesthetic practice. This guidance aims to offer pragmatic advice to support anaesthetists in caring for women during caesarean section. It emphasises the importance of non-technical skills, offers advice on best practice and aims to encourage standardisation. The guidance results from a collaborative effort by anaesthetists, psychologists and patients and has been developed to support clinicians and promote standardisation of practice in this area.

Abstract
Abstract
Study question
Does the use of 4D ultrasound to guide embryo transfers improve live birth rates in comparison to the clinical touch technique?
Summary answer
4D ultrasound guided embryo transfers (4DUS) result in significantly higher live birth rates (LBR) in comparison to those performed using the clinical touch technique (CTT)(41%vs28%).
What is known already
A previous Cochrane review showed ultrasound guided embryo transfers (ET) improve pregnancy outcomes in comparison to CTT; however there was a large degree of heterogeneity between the studies and the largest study in the review showed no difference between ultrasound guidance and CTT. A further study demonstrated no difference in ongoing pregnancy rates between 2D vs 3D ultrasound guided embryo transfers, however this study did not use LBR as an endpoint and did not report on procedure duration/difficultly, both of which are known to impact ET success rates.
Study design, size, duration
This was a prospective, open labelled randomised controlled trial comparing superiority between two techniques for ET (4DUS vs CTT). A total of 320 (n = 160/group) patients were recruited using computer generated randomisation that were centrally distributed in consecutive sealed opaque envelopes between July 2018 to December 2019. Main outcomes were clinical pregnancy rate (CPR) and LBR. Following the procedure, participants completed a survey based on their comfort and satisfaction.
Participants/materials, setting, methods
Inclusion criteria included single blastocyst transfer and a normal uterine cavity. Participants were recruited and randomized on the day of ET. Those allocated to the CTT group, had their embryo transferred without ultrasound, depositing the embryo 6cm from the external os. Those in the 4DUS group had their ET using transvaginal 4D ultrasonography and had their embryos deposited at the maximal implantation point (MIP).
Main results and the role of chance
Results were available from a total of 295 women (8% attrition rate, CTT n = 153; 4DUS n = 142)).
No demographic differences between the two groups (CTT and 4DUS) were noted including age (p = 0.05), BMI (p = 0.29), duration of infertility (p = 0.94), type of infertility (p = 0.68) or embryo quality (p = 0.89). All the 4DUS and 95% of the CTT group were performed by the same practitioner.
The 4DUS resulted in significantly higher CPR (50% vs 36% p = 0.015, OR 1.78 (1.12-2.84)) and LBR (41%vs 28%, p = 0.021, OR 1.77 (1.09-2.87)).
There were no statistically significant differences between miscarriage (p = 0.494), pregnancy of unknown location (p = 0.141) or ectopic pregnancy rates (p = 0.958) between the two groups. The 4DUS process took significantly longer time compared with the CTT procedure (15.7 vs 10.2 minutes respectively, p < 0.01). The results of the survey showed no statistical difference between patient comfort (p = 0.17) or satisfaction (p = 0.08) between the groups however there were significantly more positive comments in the 4DUS (p < 0.01). In the 4DUS group there was no difference in mean endometrial thickness (P = 0.186) or endometrial volume (p = 0.836) between pregnant and non-pregnant patients.
Limitations, reasons for caution
Due to the nature of this trial we were unable to blind the participants due to the obvious differences between the methods. Wallace catheters were used for the CTT and Kitazato catheters for the 4DUS, whilst a methodological weakness; previous meta-analysis has not shown any difference between different soft catheters.
Wider implications of the findings
LBRs, when utilizing 4DUS, are significantly higher than the current UK average (41%vs22-23%) and significantly higher than CTT. 4DUS allows for superior imaging of the uterine cavity, tailoring the embryo deposition point specifically to the patient. Further RCTs are required to confirm that 4DUS is the superior technique for ET.

Abstract
Somatic cell reprogramming and tissue repair share relevant factors and molecular programs. Here, Dickkopf-3 (DKK3) is identified as novel factor for organ regeneration using combined transcription-factor-induced reprogramming and RNA-interference techniques. Loss of Dkk3 enhances the generation of induced pluripotent stem cells but does not affect de novo derivation of embryonic stem cells, three-germ-layer differentiation or colony formation capacity of liver and pancreatic organoids. However, DKK3 expression levels in wildtype animals and serum levels in human patients are elevated upon injury. Accordingly, Dkk3-null mice display less liver damage upon acute and chronic failure mediated by increased proliferation in hepatocytes and LGR5+ liver progenitor cell population, respectively. Similarly, recovery from experimental pancreatitis is accelerated. Regeneration onset occurs in the acinar compartment accompanied by virtually abolished canonical-Wnt-signaling in Dkk3-null animals. This results in reduced expression of the Hedgehog repressor Gli3 and increased Hedgehog-signaling activity upon Dkk3 loss. Collectively, these data reveal Dkk3 as a key regulator of organ regeneration via a direct, previously unacknowledged link between DKK3, canonical-Wnt-, and Hedgehog-signaling.

Abstract
We report the first measurement of the average of the electron-proton and positron-proton elastic scattering cross sections. This lepton charge-averaged cross section is insensitive to the leading effects of hard two-photon exchange, giving more robust access to the proton's electromagnetic form factors. The cross section was extracted from data taken by the OLYMPUS experiment at DESY, in which alternating stored electron and positron beams were scattered from a windowless gaseous hydrogen target. Elastic scattering events were identified from the coincident detection of the scattered lepton and recoil proton in a large-acceptance toroidal spectrometer. The luminosity was determined from the rates of Møller, Bhabha, and elastic scattering in forward electromagnetic calorimeters. The data provide some selectivity between existing form factor global fits and will provide valuable constraints to future fits.

Abstract
Next generation sequencing studies have highlighted discrepancies in β-cells which exist between mice and men. Numerous reports have identified MAF BZIP Transcription Factor B (MAFB) to be present in human β-cells postnatally, while its expression is restricted to embryonic and neo-natal β-cells in mice. Using CRISPR/Cas9-mediated gene editing, coupled with endocrine cell differentiation strategies, we dissect the contribution of MAFB to β-cell development and function specifically in humans. Here we report that MAFB knockout hPSCs have normal pancreatic differentiation capacity up to the progenitor stage, but favor somatostatin- and pancreatic polypeptide–positive cells at the expense of insulin- and glucagon-producing cells during endocrine cell development. Our results describe a requirement for MAFB late in the human pancreatic developmental program and identify it as a distinguishing transcription factor within islet cell subtype specification. We propose that hPSCs represent a powerful tool to model human pancreatic endocrine development and associated disease pathophysiology. The MAF bZIP transcription factor B (MAFB) is present in postnatal human beta cells but its role is unclear. Here, the authors show that MAFB regulates endocrine pancreatic cell fate specification.

Abstract
The UCNA experiment was designed to measure the neutron β-asymmetry parameter A0 using polarized ultracold neutrons (UCN). UCN produced via downscattering in solid deuterium were polarized via transport through a 7 T magnetic field, and then directed to a 1 T solenoidal electron spectrometer, where the decay electrons were detected in electron detector packages located on the two ends of the spectrometer. A value for A0 was then extracted from the asymmetry in the numbers of counts in the two detector packages. We summarize all of the results from the UCNA experiment, obtained during run periods in 2007, 2008–2009, 2010, and 2011–2013, which ultimately culminated in a 0.67% precision result for A0.

Abstract
Objective It is typical in epidemiological research of osteoarthritis (OA) to collect data for the hand, hip, and knee. However, little population‐based data exist for this disease in the foot. Thus, we addressed patterns of OA for the foot compared with the hand, hip, and knee spanning 2000/2001 to 2017/2018 in England. Methods Secondary‐care data from 3 143 928 patients with OA of the foot, hand, hip, and knee were derived from the National Health Service (NHS) Hospital Episode Statistics (HES) database. Distribution, population prevalence, and incidence of joint‐specific OA were stratified by age and sex. Results OA incidence increased significantly at the foot [3.8% (95% confidence interval [CI] 3.0, 4.6)], hand [10.9% (10.1, 11.7)], hip [3.8% (2.9, 4.7)], and knee [2.9% (2.2, 3.6)] per year from 2000/2001 to 2017/2018. A higher proportion of women were diagnosed with OA, whereas greater incidence in men was estimated for the hand and hip. Foot OA presented comparable diagnosis numbers to the hand. More recently during 2012/2013 to 2017/2018, a significant rise in hip OA was estimated among younger adults, whereas knee OA decreased across all age groups. Incidence of OA in the foot and hand were particularly significant among the 75 or older age group, though bimodal age distributions were observed for both sites. Conclusion The significant increase in secondary care records for OA in England underscores the importance of exploring possible causative factors and identifying groups most at risk. Further detailed data may be particularly important for the hip, which represents significant incidence among younger adults. Greater incidence of OA in the foot compared with the knee emphasizes the need for well‐conducted epidemiological research in this area. Monitoring the performance of surgical outcomes at the population‐level for this frequently affected yet understudied site could have substantial potential to reduce the socioeconomic burden it represents to the NHS.

Abstract
The 2009-12 MBRRACE-UK report highlighted the deaths of two women in whom dural puncture had occurred during insertion of a labour epidural catheter. Despite suffering long-term headaches, neither woman was adequately followed-up after discharge from hospital. Death resulted from a cerebral vein thrombosis in one case and a subdural haematoma in the other. Due to significant variation in the treatment of obstetric post-dural puncture headache, an Obstetric Anaesthetists' Association working group was set up to produce evidence-based guidelines to guide clinicians. These guidelines have been condensed into two review articles. In this second review, the role of an epidural blood patch is discussed using a question and answer format.

Abstract
The integration of genomic and transcriptomic profiles of 2000 breast tumours from the METABRIC [Molecular Taxonomy of Breast Cancer International Consortium] cohort revealed ten subtypes, termed integrative clusters (IntClust/s), characterised by distinct genomic drivers. Central histopathology (N = 1643) review was undertaken to explore the relationship between these ten molecular subtypes and traditional clinicopathological features. IntClust subtypes were significantly associated with histological type, tumour grade, receptor status, and lymphocytic infiltration (p < 0.0001). Lymph node status and Nottingham Prognostic Index [NPI] categories were also significantly associated with IntClust subtype. IntClust 3 was enriched for tubular and lobular carcinomas, the latter largely accounting for the association with CDH1 mutations in this cluster. Mucinous carcinomas were not present in IntClusts 5 or 10, but did not show an association with any of the remaining IntClusts. In contrast, medullary-like cancers were associated with IntClust 10 (15/26). Hormone receptor-positive tumours were scattered across all IntClusts. IntClust 5 was dominated by HER2 positivity (127/151), including both hormone receptor-positive (60/72) and hormone receptor-negative tumours (67/77). Triple-negative tumours comprised the majority of IntClust 10 (132/159) and around a quarter of IntClust 4 (52/217). Whilst the ten IntClust subtypes of breast cancer show characteristic patterns of association with traditional clinicopathological variables, no IntClust can be adequately identified by these variables alone. Hence, the addition of genomic stratification has the potential to enhance the biological relevance of the current clinical evaluation and facilitate genome-guided therapeutic strategies.

Abstract
The OLYMPUS Collaboration reports on a precision measurement of the positron-proton to electron-proton elastic cross section ratio, R_{2γ}, a direct measure of the contribution of hard two-photon exchange to the elastic cross section. In the OLYMPUS measurement, 2.01 GeV electron and positron beams were directed through a hydrogen gas target internal to the DORIS storage ring at DESY. A toroidal magnetic spectrometer instrumented with drift chambers and time-of-flight scintillators detected elastically scattered leptons in coincidence with recoiling protons over a scattering angle range of ≈20° to 80°. The relative luminosity between the two beam species was monitored using tracking telescopes of interleaved gas electron multiplier and multiwire proportional chamber detectors at 12°, as well as symmetric Møller or Bhabha calorimeters at 1.29°. A total integrated luminosity of 4.5 fb^{-1} was collected. In the extraction of R_{2γ}, radiative effects were taken into account using a Monte Carlo generator to simulate the convolutions of internal bremsstrahlung with experiment-specific conditions such as detector acceptance and reconstruction efficiency. The resulting values of R_{2γ}, presented here for a wide range of virtual photon polarization 0.456<ε<0.978, are smaller than some hadronic two-photon exchange calculations predict, but are in reasonable agreement with a subtracted dispersion model and a phenomenological fit to the form factor data.

Abstract
Pluripotency represents a cell state comprising a fine-tuned pattern of transcription factor activity required for embryonic stem cell (ESC) self-renewal. TBX3 is the earliest expressed member of the T-box transcription factor family and is involved in maintenance and induction of pluripotency. Hence, TBX3 is believed to be a key member of the pluripotency circuitry, with loss of TBX3 coinciding with loss of pluripotency. We report a dynamic expression of TBX3 in vitro and in vivo using genetic reporter tools tracking TBX3 expression in mouse ESCs (mESCs). Low TBX3 levels are associated with reduced pluripotency, resembling the more mature epiblast. Notably, TBX3-low cells maintain the intrinsic capability to switch to a TBX3-high state and vice versa. Additionally, we show TBX3 to be dispensable for induction and maintenance of naive pluripotency as well as for germ cell development. These data highlight novel facets of TBX3 action in mESCs.

Abstract
Three groups of rats ( n = 6) were given prior experience in a Skinner box before being trained in a two-way shuttlebox-avoidance task. Subjects experiencing controllable shock (avoidable or escapable) performed significantly better than a yoked control group which had no control over shocks in the Skinner box and better than a control group which experienced no shock in the Skinner box. Results can be interpreted adequately in terms of the learned helplessness hypothesis proposed by Maier, Seligman, and Solomon.

Abstract
Abstract
Background: It is unclear if all breast cancer (BC) patients require baseline left ventricular function (LVEF) assessment prior to anthracycline based chemotherapy (ABC), and the approach is variable in clinical practice. Our objective is to determine the cost effectiveness of obtaining a baseline LVEF assessment prior to (neo) adjuvant ABC in clinical practice.
Methods: We performed a retrospective analysis of the Yale Equilibrium Radionuclide Angiography (ERNA) database for 701 breast cancer patients who had a baseline ERNA scan prior to systemic therapy for an initial diagnosis of stages I-IV BC between July 2003 and May 2013. We found that 14 of 701 (2%) patients had a baseline LVEF < 50%. Age, pre-existing cardiac risk factors and coronary artery disease did not predict an abnormal baseline LVEF <50 %. To evaluate the benefit of obtaining a baseline echocardiogram or ERNA before ABC, we considered the screening scenario in which BC patients with a baseline LVEF < 50% on screening echocardiogram are treated with a second (2nd) generation non-ABC and those with baseline LVEF ≥ 50% receive a third (3rd) generation ABC, and compared this with a non-screening scenario with uniform 3rd generation ABC treatment for all patients who do not have a baseline echocardiogram. We used Adjuvant Online to obtain estimates of the disease free (DFS) and overall survival (OS) for a 3rd generation ABC regimen vs a 2nd generation non-ABC regimen for 50 year old patients with a T2N1 hormone receptor positive BC. We implemented these oncologic clinical outcomes (in addition to cardiotoxicity-related clinical outcomes, costs of screening echocardiogram and treatment of congestive heart failure (CHF), quality of life metrics, as reported in the literature) into a simplified decision-analytic cost-effectiveness analysis that accounts for the different disease states and their associated costs and quality of life outcomes.
Results: Assuming that 20% of the unscreened patients with a LVEF < 50% will develop CHF if treated with ABC regimen without management of baseline cardiac dysfunction, the base case incremental cost effectiveness ratio (ICER) was determined to be 18,520 $USD/QALY. Sensitivity analysis suggested that the cost-effectiveness of baseline LVEF assessment is primarily driven by the prevalence of patients with LVEF < 50%, the incidence of CHF in this high-risk patient group if treated with ABC regimen, and time to CHF development. While our analysis did not reveal risk factors predictive of low baseline LVEF, our model's dependence on prevalence of LVEF < 50% demonstrates the importance of risk factor stratification. A hypothetical predictive marker which enriches the prevalence of an abnormal baseline LVEF 5-fold to 10% would result in a cost-effectiveness of 10,990 $USD/QALY. The model is less sensitive to the cost of baseline echocardiogram testing.
Conclusion: Baseline LVEF assessment was found to be cost-effective under a willingness-to-pay threshold of $50,000/QALY. Our sensitivity analysis suggests that risk factor-guided LVEF baseline LVEF screening may increase the number of high-risk patients in the treatment population, thus further increasing the cost-effectiveness of baseline LVEF assessment.

Abstract
BACKGROUND Understanding the heterogeneous genotypes and phenotypes of prostate cancer is fundamental to improving the way we treat this disease. As yet, there are no validated descriptions of prostate cancer subgroups derived from integrated genomics linked with clinical outcome. METHODS In a study of 482 tumour, benign and germline samples from 259 men with primary prostate cancer, we used integrative analysis of copy number alterations (CNA) and array transcriptomics to identify genomic loci that affect expression levels of mRNA in an expression quantitative trait loci (eQTL) approach, to stratify patients into subgroups that we then associated with future clinical behaviour, and compared with either CNA or transcriptomics alone. FINDINGS We identified five separate patient subgroups with distinct genomic alterations and expression profiles based on 100 discriminating genes in our separate discovery and validation sets of 125 and 103 men. These subgroups were able to consistently predict biochemical relapse (p = 0.0017 and p = 0.016 respectively) and were further validated in a third cohort with long-term follow-up (p = 0.027). We show the relative contributions of gene expression and copy number data on phenotype, and demonstrate the improved power gained from integrative analyses. We confirm alterations in six genes previously associated with prostate cancer (MAP3K7, MELK, RCBTB2, ELAC2, TPD52, ZBTB4), and also identify 94 genes not previously linked to prostate cancer progression that would not have been detected using either transcript or copy number data alone. We confirm a number of previously published molecular changes associated with high risk disease, including MYC amplification, and NKX3-1, RB1 and PTEN deletions, as well as over-expression of PCA3 and AMACR, and loss of MSMB in tumour tissue. A subset of the 100 genes outperforms established clinical predictors of poor prognosis (PSA, Gleason score), as well as previously published gene signatures (p = 0.0001). We further show how our molecular profiles can be used for the early detection of aggressive cases in a clinical setting, and inform treatment decisions. INTERPRETATION For the first time in prostate cancer this study demonstrates the importance of integrated genomic analyses incorporating both benign and tumour tissue data in identifying molecular alterations leading to the generation of robust gene sets that are predictive of clinical outcome in independent patient cohorts.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is associated with accumulation of particular oncogenic mutations and recent genetic sequencing studies have identified ataxia telangiectasia-mutated (ATM) mutations in PDAC cohorts. Here we report that conditional deletion of ATM in a mouse model of PDAC induces a greater number of proliferative precursor lesions coupled with a pronounced fibrotic reaction. ATM-targeted mice display altered TGFβ-superfamily signalling and enhanced epithelial-to-mesenchymal transition (EMT) coupled with shortened survival. Notably, our mouse model recapitulates many features of more aggressive human PDAC subtypes. Particularly, we report that low expression of ATM predicts EMT, a gene signature specific for Bmp4 signalling and poor prognosis in human PDAC. Our data suggest an intimate link between ATM expression and pancreatic cancer progression in mice and men.

Abstract
Human mRNA DeXD/H-box helicases are ubiquitous molecular motors that are required for the majority of cellular processes that involve RNA metabolism. One of the most abundant is eIF4A, which is required during the initiation phase of protein synthesis to unwind regions of highly structured mRNA that would otherwise impede the scanning ribosome. Dysregulation of protein synthesis is associated with tumorigenesis, but little is known about the detailed relationships between RNA helicase function and the malignant phenotype in solid malignancies. Therefore, immunohistochemical analysis was performed on over 3000 breast tumors to investigate the relationship among expression of eIF4A1, the helicase-modulating proteins eIF4B, eIF4E and PDCD4, and clinical outcome. We found eIF4A1, eIF4B and eIF4E to be independent predictors of poor outcome in ER-negative disease, while in contrast, the eIF4A1 inhibitor PDCD4 was related to improved outcome in ER-positive breast cancer. Consistent with these data, modulation of eIF4A1, eIF4B and PCDC4 expression in cultured MCF7 cells all restricted breast cancer cell growth and cycling. The eIF4A1-dependent translatome of MCF7 cells was defined by polysome profiling, and was shown to be highly enriched for several classes of oncogenic genes, including G-protein constituents, cyclins and protein kinases, and for mRNAs with G/C-rich 5'UTRs with potential to form G-quadruplexes and with 3'UTRs containing microRNA target sites. Overall, our data show that dysregulation of mRNA unwinding contributes to the malignant phenotype in breast cancer via preferential translation of a class of genes involved in pro-oncogenic signaling at numerous levels. Furthermore, immunohistochemical tests are promising biomarkers for tumors sensitive to anti-helicase therapies.
