Abstract
BACKGROUND There is growing interest in use of entrustable professional activity (EPA)-grounded workplace-based assessments (WBAs) to assess medical students through direct observation in the clinical setting. However, there has been very little reflection on how these tools are received by the faculty using them to deliver feedback. Faculty acceptance of WBAs is fundamentally important to sustained utilisation in the clinical setting, and understanding faculty perceptions of the WBA as an adjunct for giving targeted feedback is necessary to guide future faculty development in this area. APPROACH Use of a formative EPA-grounded WBA was implemented in the ambulatory setting during the paediatrics clerkship following performance-driven training and frame-of-reference training with faculty. Surveys and semi-structured interviews with faculty members explored how faculty perceived the tool and its impact on feedback delivery. EVALUATION Faculty reported providing more specific, task-oriented feedback following implementation of the WBA, as well as greater timeliness of feedback and greater satisfaction with opportunities to provide feedback, although these later two findings did not reach significance. Themes from the interviews reflected the benefits of WBAs, persistent barriers to the provision of feedback and suggestions for improvement of the WBA. IMPLICATIONS EPA-grounded WBAs are feasible to implement in the outpatient primary care setting and improve feedback delivery around core EPAs. The WBAs positively impacted the way faculty conceptualise feedback and provide learners with more actionable, behaviour-based feedback. Findings will inform modifications to the WBA and future faculty development and training to allow for sustainable WBA utilisation in the core clerkship.

Abstract
BACKGROUND There is little currently little information available regarding the nature of the advice requests veterinary dermatologists receive from general practitioners. Collation of such data could direct continuing veterinary development in the future. METHODS Dermatologists completed hand-written recording sheets during or after enquiries. Information recorded included the route of enquiry, nature of advice, material provided, practice type and location, animal signalment, presenting signs, diagnosis/differential diagnosis, treatment and referral recommendations, time taken and if charges were made. RESULTS Twelve dermatology services recorded 768 advice requests over a 6-month period. Most requests were submitted via email and related to canine dermatology (81%). An average of 9.5 minutes was spent replying to requests. Charges were made in 2% of cases. Advice regarding otitis was most commonly sought, followed by pruritus, alopecia and crusting. The most frequently discussed diagnoses included allergy, otitis, pyoderma, demodicosis, dermatophytosis and neoplasia. Antibiotics, anti-pruritics and topical otic medications were the most commonly discussed therapeutics. LIMITATIONS This is an initial study and therefore there are limitations involving the depth of the data. Additional studies should be completed which identify why advice is sought, decision-making regarding referral, and if advice should be charged similarly to other disciplines. CONCLUSIONS These findings highlight that veterinarians mostly frequently seek advice on management of common dermatological problems, including allergy, otitis and pyoderma.

Abstract
OBJECTIVES Assessing the cost-effectiveness of complex pharmaceutical care interventions and medication error outcomes is hindered by lack of available data on actual outcomes consequent to errors that were intercepted for patient safety reasons. Expert judgement is an approach to acquire data regarding unknown parameters in an economic model which are otherwise insufficient or not possible to obtain. The aim of this paper is to describe a method to approach this problem using findings from a single intervention study and to calculate the potential costs and consequences associated with discharge medication error. METHODS Using data from a previous intervention study, the hypothetical consequences of medication error(s) at hospital discharge, in terms of diagnosis, healthcare resource utilisation and impact on health-related quality of life, were identified by expert judgement of anonymised cases. Primary healthcare utilisation costs were derived from published tariffs, inpatient costs were derived by simulation in the hospital discharge activity database test environment and the difference between adjudicated baseline and posterror health state was expressed as quality-adjusted life year (QALY) decrement. RESULTS Four experts provided judgement on 81 cases. Of these, 75 were judged to have potential clinical consequences. Between 56 and 69 of the 81 cases were variably judged to require remedial healthcare utilisation. The mean calculated cost per case (representing an individual patient), based on all 81 cases, was €1009.58, 95% CI 726.64 to 1585.67. The mean QALY loss was 0.03 (95% CI 0.01 to 0.05). CONCLUSION An expert judgement process proved feasible and useful to estimate financial cost and QALY loss associated with hospital discharge medication error. These estimates will be employed in model-based economic evaluation. This method could be transferred to other prospective observational patient safety research which seeks to assess value for money of complex interventions.

Abstract
BACKGROUND In the face of the COVID-19 pandemic, the Defence Science and Technology Laboratory (Dstl) and Defence Pathology combined to form the Defence Clinical Lab (DCL), an accredited (ISO/IEC 17025:2017) high-throughput SARS-CoV-2 PCR screening capability for military personnel. LABORATORY STRUCTURE AND RESOURCE The DCL was modular in organisation, with laboratory modules and supporting functions combining to provide the accredited SARS-CoV-2 (envelope (E)-gene) PCR assay. The DCL was resourced by Dstl scientists and military clinicians and biomedical scientists. LABORATORY RESULTS Over 12 months of operation, the DCL was open on 289 days and tested over 72 000 samples. Six hundred military SARS-CoV-2-positive results were reported with a median E-gene quantitation cycle (Cq) value of 30.44. The lowest Cq value for a positive result observed was 11.20. Only 64 samples (0.09%) were voided due to assay inhibition after processing started. CONCLUSIONS Through a sustained effort and despite various operational issues, the collaboration between Dstl scientific expertise and Defence Pathology clinical expertise provided the UK military with an accredited high-throughput SARS-CoV-2 PCR test capability at the height of the COVID-19 pandemic. The DCL helped facilitate military training and operational deployments contributing to the maintenance of UK military capability. In offering a bespoke capability, including features such as testing samples in unit batches and oversight by military consultant microbiologists, the DCL provided additional benefits to the UK Ministry of Defence that were potentially not available from other SARS-CoV-2 PCR laboratories. The links between Dstl and Defence Pathology have also been strengthened, benefitting future research activities and operational responses.

Abstract
There are more than 70 distinct sarcomas, and this diversity complicates the development of precision-based therapeutics for these cancers. Prospective comprehensive genomic profiling could overcome this challenge by providing insight into sarcomas' molecular drivers. Through targeted panel sequencing of 7494 sarcomas representing 44 histologies, we identify highly recurrent and type-specific alterations that aid in diagnosis and treatment decisions. Sequencing could lead to refinement or reassignment of 10.5% of diagnoses. Nearly one-third of patients (31.7%) harbor potentially actionable alterations, including a significant proportion (2.6%) with kinase gene rearrangements; 3.9% have a tumor mutational burden ≥10 mut/Mb. We describe low frequencies of microsatellite instability (<0.3%) and a high degree of genome-wide loss of heterozygosity (15%) across sarcomas, which are not readily explained by homologous recombination deficiency (observed in 2.5% of cases). In a clinically annotated subset of 118 patients, we validate actionable genetic events as therapeutic targets. Collectively, our findings reveal the genetic landscape of human sarcomas, which may inform future development of therapeutics and improve clinical outcomes for patients with these rare cancers.

Abstract
Introduction Digital health, the use of apps, text-messaging, and online interventions, can revolutionize healthcare and make care more equitable. Currently, digital health interventions are often not designed for those who could benefit most and may have unintended consequences. In this paper, we explain how privacy vulnerabilities and power imbalances, including racism and sexism, continue to influence health app design and research. We provide guidelines for researchers to design, report and evaluate digital health studies to maximize social justice in health. Methods From September 2020 to April 2021, we held five discussion and brainstorming sessions with researchers, students, and community partners to develop the guide and the key questions. We additionally conducted an informal literature review, invited experts to review our guide, and identified examples from our own digital health study and other studies. Results We identified five overarching topics with key questions and subquestions to guide researchers in designing or evaluating a digital health research study. The overarching topics are: 1. Equitable distribution; 2. Equitable design; 3. Privacy and data return; 4. Stereotype and bias; 5. Structural racism. Conclusion We provide a guide with five key topics and questions for social justice digital health research. Encouraging researchers and practitioners to ask these questions will help to spark a transformation in digital health toward more equitable and ethical research. Future work needs to determine if the quality of studies can improve when researchers use this guide.

Abstract
Nusinersen (NUS), the first treatment approved for Spinal Muscular Atrophy type 1 (SMA1), was made available in the UK for SMA1 through the Expanded Access Program (EAP) in 2017. The Great Ormond Street Respiratory (GSR) score was developed as an objective respiratory assessment for children with SMA1 during their treatment. Aims: Track respiratory status of SMA1 children over the course of Nusinersen treatment and compare GSR scores amongst SMA1 sub-types. Single centre study on SMA1 patients using the GSR score at set time points: prior to first NUS dose; 2 weeks post end of loading doses; 2 weeks post-subsequent doses. GSR score ranges 1-28, being 1-9 = Stable minimal support, thorough to 23-28 = Poor reserve with maximum support. 20 SMA1 children underwent NUS treatment between January 2017 - November 2018. Median age of diagnosis was 5.0 months. NUS started at median of 9.57 months. From 5th dose onwards, GSR scores were significantly lower for Type 1C patients compared to Type 1B By month 18, irrespective of subtypes, the whole cohort appears to stabilise GSR Scores. As treatment duration increases, an overall stabilisation of respiratory status across the cohort was observed. Further longitudinal studies are needed to validate the GSR.

Abstract
BACKGROUND Thrombosis in the neonatal population is rare, but increasing. Its incidence and management are not well understood. OBJECTIVES To investigate the incidence, associated factors, and management of thrombosis in the neonatal intensive care unit (NICU) population. PATIENTS/METHODS We performed a retrospective cohort study of infants admitted to a Pediatrix Medical Group-affiliated NICU from 1997 through 2015. We determined the prevalence of venous and arterial thrombosis, and assessed demographic characteristics and known risk factors. Categorical variables were compared with the Pearson χ2 test and continuous variables with Wilcoxon rank-sum tests. Stepwise logistic regression was used to identify associated factors. The primary outcome was incidence of thrombosis. Secondary analyses investigated correlations between clinical and demographic characteristics and thrombosis. RESULTS Among 1 158 755 infants, we identified 2367 (0.20%) diagnosed with thrombosis. In a multivariable regression analysis, prematurity, male sex, congenital heart disease, sepsis, ventilator support, vasopressor receipt, central venous catheter, invasive procedures, and receipt of erythropoietin were associated with increased risk of thrombosis, while Black race and Hispanic ethnicity were associated with reduced risk. The majority of infants diagnosed with thrombosis (73%) received no anticoagulation, but anticoagulant use in infants with thrombosis was higher than those without (27% versus 0.2%, P < .001). Thrombosis in infants was associated with higher mortality (11% versus 2%, P < .001) and longer hospital stays (57 days, [interquartile range (IQR) 28--100] versus 10 days, [IQR 6--22], P < .001). CONCLUSIONS In the largest national study to date, we found that thrombosis in NICU patients is associated with prematurity, low birth weight, sepsis, and invasive procedures.

Abstract
OBJECTIVE A proportion of children die, making them potentially eligible to be organ/tissue donors. Not all are approached for donation, and experiences of those parents are not well understood. The objective was to investigate to what extent organ and tissue donation (OTD) is discussed as part of end-of-life care and to explore parents' and healthcare professionals' (HCPs) experiences. DESIGN A retrospective qualitative study. SETTING Multicentre study with participants recruited through two neonatal intensive care units (ICUs), two paediatric ICUs, a cardiac ICU and a children's hospice. PATIENTS Bereaved parents, parents of a child with a long-term condition (LTC) and HCPs. INTERVENTIONS None. MAIN OUTCOMES AND MEASURES Parents' and HCPs' views and experiences of discussions about OTD. RESULTS 24 parents of 20 children were interviewed: 21 bereaved parents and 3 parents of a child with a LTC. Seven parents were asked about donation (13 not asked), four agreed and two donated. 41 HCPs were interviewed. Themes: complexity of donation process, OTD as a coping strategy, the importance of asking, difficulty of raising the topic,\ and parents' assumptions about health of organs (when donation is not discussed). CONCLUSIONS The findings add new knowledge about parents' assumptions about the value of their child's organs when discussions about OTD are not raised, and that HCPs do not routinely ask, are sometimes hesitant to ask in fear of damaging relationships, and the reality of the complexity of the donation process. Given the current levels of awareness around OTD, the topic should be raised.

Abstract
Pain neurophysiology education (PNE) is an educational intervention for patients with chronic pain. PNE purports to assist patients to reconceptualise their pain away from the biomedical model towards a more biopsychosocial understanding by explaining pain biology. This study aimed to explore the extent, and nature, of patients' reconceptualisation of their chronic low back pain (CLBP) following PNE. Eleven adults with CLBP underwent semistructured interviews before and three weeks after receiving PNE. Interviews were transcribed verbatim and thematically analysed in a framework approach using four a priori themes identified from our previous research: (1) degrees of reconceptualisation, (2) personal relevance, (3) importance of prior beliefs, and (4) perceived benefit of PNE. We observed varying degrees of reconceptualisation from zero to almost complete, with most participants showing partial reconceptualisation. Personal relevance of the information to participants and their prior beliefs were associated with the degree of benefit they perceived from PNE. Where benefits were found, they manifested as improved understanding, coping, and function. Findings map closely to our previous studies in more disparate chronic pain groups. The phenomenon of reconceptualisation is applicable to CLBP and the sufficiency of the themes from our previous studies increases confidence in the certainty of the findings.

Abstract
Background This narrative review explores the ways in which drawing on theories and methods used in sociological work on footwear and identity can contribute to healthcare research with podiatrists and their patients, highlighting recent research in this field, implications for practice and potential areas for future development. Traditionally, research within Podiatry Services has tended to adopt a quantitative, positivist focus, developing separately from a growing body of sociological work exploring the importance of shoes in constructing identity and self-image. Bringing qualitative research drawing on sociological theory and methods to the clinical encounter has real potential to increase our understanding of patient values, motivations and – crucially – any barriers to adopting ‘healthier’ footwear that they may encounter. Such work can help practitioners to understand why patients may resist making changes to their footwear practices, and help us to devise new ways for practitioners to explore and ultimately break down individual barriers to change (including their own preconceptions as practitioners). This, in turn, may lead to long-term, sustainable changes to footwear practices and improvements in foot health for those with complex health conditions and the wider population. Conclusion A recognition of the complex links between shoes and identity is opening up space for discussion of patient resistance to footwear changes, and paving the way for future research in this field beyond the temporary ‘moment’ of the clinical encounter.

Abstract
11001 Background: The utility of NGS in management of sarcoma pts remains undefined. Methods: We retrospectively analyzed the NGS profile of patients who were sequenced using a panel of 405 cancer-related genes in DNA and 265 genes rearranged in RNA. Diagnostic and therapeutic implications of mutations (mut) were evaluated through published literature (OncoKb.org, Pubmed). An algorithm was applied to determine germline mut. Following IRB approval, we evaluated the clinical outcomes of pts who underwent NGS at MSKCC. Results: From 2012–2016, 5635 pts worldwide with 56 histologies were tested. Median age of 52 yrs ( < 1-88), 52% females and sarcoma NOS (n = 858) was most frequent. Tumors were sequenced to a mean coverage of 634X; 1165 fusions and > 60,000 mut were found. Mut suspicious for germline defects were seen in 542 pts (9.6%) in known and novel genes ( BRCA, ARID1, FANC). Tumor mutational burden was 2.5/Mb (0–329) and glomus tumors and EHE had the highest and lowest mut, respectively. 16% and 7% of pts had treatment-linked alterations (TLA) known to respond to an FDA approved or study drug, respectively. 42% of pts had TLA eligible for NCI-MATCH, ASCO-TAPUR or other studies. Novel TLA include AKT, ESR1, BRCA, NTRK, PTCH1, SMARCB1 and others. Of the 107 MSKCC pts with clinical data, 60/107 (57%) had at least one TLA, of which 31 (30%) enrolled on a matched trial and 26 pts were ineligible or lacked access to trials. Partial/complete responses were seen with inhibitors to NTRK, IDH1, BRAF, PI3K/mTOR, MDM2, SMARCB1 and others. NGS changed the initial pathology diagnosis and treatments in 5% pts (e.g. LMS to liposarcoma, clear cell to melanoma). Resistance mutations averted futile therapies in 5% pts (e.g. Rb loss and palbociclib in liposarcoma). Conclusions: Our data suggests that NGS has a significant impact in aiding diagnosis and selecting matched therapies in sarcoma. Suspected germline aberrations, while intriguing, needs further validation.

Abstract
Introduction This feasibility study aimed to (i) develop a clinical protocol using a long-term potentiation-like repetitive stimulation protocol for transcutaneous electrical nerve stimulation in patients with upper limb complex regional pain syndrome and (ii) develop a research protocol for a single-blind randomised controlled trial investigating the efficacy of transcutaneous electrical nerve stimulation for complex regional pain syndrome. Methods This small-scale single-blind feasibility randomised-controlled trial planned to randomise 30 patients with upper limb complex regional pain syndrome to either a variant of transcutaneous electrical nerve stimulation or placebo transcutaneous electrical nerve stimulation for three weeks. Stimulation comprised 20 pulses over 1 s with a non-stimulation interval of 5 s, a so-called repetitive electrical stimulation protocol following the timing of long-term potentiation. Pain, function and body image were measured at baseline, post-treatment and at three months follow-up. At three months, participants were invited to one-to-one interviews, which were analysed thematically. Results A transcutaneous electrical nerve stimulation protocol with electrodes applied proximal to the area of allodynia in the region of the upper arm was developed. Participant concordance with the protocol was high. Recruitment was below target (transcutaneous electrical nerve stimulation (n = 6), placebo (n = 2)). Mean (SD) pain intensity for the transcutaneous electrical nerve stimulation group on a 0 to 10 scale was 7.2 (2.4), 6.6 (2.8) and 7.8 (1.9), at baseline, post-treatment and at three-month follow-up, respectively. Qualitative data suggested that some patients found transcutaneous electrical nerve stimulation beneficial, easy to use and were still using it at three months. Conclusion Patients tolerated transcutaneous electrical nerve stimulation well, and important methodological information to facilitate the design of a large-scale trial was obtained (ISRCTN48768534).

Abstract
OBJECTIVE Pain neurophysiology education (PNE), a method of pain education, purports to work by helping patients reconceptualise their pain, shifting from a tissue injury model towards a biopsychosocial understanding related to neural sensitivity. Better understanding of pain reconceptualisation following PNE is needed to improve the delivery of this educational approach to enhance its effectiveness. This study aimed to investigate the extent and nature of reconceptualisation following PNE. METHODS In a qualitative design, based on Interpretive Phenomenological Analysis, thematic analysis was carried out on individual interviews with 7 adults before and three weeks after receiving PNE at a pain clinic. RESULTS Three themes emerged describing variable degrees of reconceptualisation; prior beliefs as facilitators and barriers to reconceptualisation; and the influence of reconceptualisation on clinical benefits of PNE. CONCLUSION The results lend support to claims that reconceptualisation is an important mechanism in PNE and justify further investigation of this phenomenon. PRACTICAL IMPLICATIONS When delivering PNE to patients with chronic pain helping patients to reconceptualise their pain may be key to enhancing the clinical benefits of the intervention. Understanding prior beliefs may be an important step in facilitating reconceptualisation.

Abstract
BACKGROUND A previous study highlighted the importance of footwear to individuals' sense of their identity, demonstrating that shoes must 'fit' someone socially, as well as functionally. However, unhealthy shoes can have a detrimental effect on both foot health and mobility. This project utilises qualitative social science methods to enable podiatrists to understand the broader contribution of footwear to patients' sense of themselves and from this an online toolkit was developed to aid footwear education. METHOD Semi-structured interviews were conducted with six podiatrists/shoe-fitters and 13 people with foot pathologies, some of whom also completed shoe diaries. These were supplemented with some follow-up interviews and photographs of participants' own shoes were taken to allow in-depth discussions. RESULTS Four areas related to 'fit' were identified; practicalities, personal, purpose and pressures, all of which need to be considered when discussing changes in footwear. These were incorporated into an online toolkit which was further validated by service users and practitioners in a focus group. CONCLUSION This toolkit can support podiatrists in partnership with patients to identify and address possible barriers to changing footwear towards a more suitable shoe. Enabling patients to make healthier shoe choices will help contribute to improvements in their foot health and mobility.

Abstract
This article addresses theoretical problems around the notion of ‘choice’, using empirical data from a three-year, ESRC-funded study of identity, transition and footwear among both women and men. With a focus on female participants who wore, or had worn high-heeled shoes, it draws on Budgeon’s argument for viewing the body as event, as becoming, and Finch’s use of the concept of display, to explore the temporalities of high-heeled shoe wear, particularly as an aspect of ‘dressing up’. Data from both focus groups and year-long case studies allowed everyday and life course patterns of high-heeled shoe wear to be explored – in many cases, as they unfolded. This material has led us to critique the linear, goal-oriented nature of a modernist ‘project of the self’, and to argue that identification, as a dynamic process, may often be erratic, partial and temporary. Emphasized femininity, it is suggested, can be ‘displayed’ episodically, as an aspect of ‘doing gender’, a perspective that problematizes notions of a ‘post-feminist masquerade’ that inevitably secures gender retrenchment. Through an examination of the occasions and non-occasions that pattern the temporalities of women’s lives, therefore, the article demonstrates a distinction between displaying femininity and doing gender, one that simultaneously sheds light on their relationship with one another.

Abstract
Abstract
In addition to longevity enhancement, calorie restriction has been reported to slow the appearance of aging-related T cell abnormalities. However, the molecular mechanism underlying this phenomenon is ill-defined. We report that short-term calorie restriction in mice conferred protection to naïve CD8+ T cells from death-by-neglect, as compared to cells isolated from mice fed ad libitum. An ortholog of the forkhead transcription factor, Foxo1, is required for the longevity benefits of calorie restriction in C. elegans. Therefore, mice with a conditional, T cell-specific deficiency of Foxo1 were also subjected to calorie restriction. Calorie restriction in the absence of Foxo1 did not result in reduced naïve CD8+ T cell death by neglect. Naïve CD8+ T cells isolated from calorie restricted mice express higher levels of the cell surface receptors, CD8 and CD127, both of which are responsible for receiving homeostatic survival signals in vivo. Thus, Foxo1 coordinates an intrinsic transcriptional response to calorie restriction that alters the sensitivity of naïve CD8+ T cells to homeostatic signals. Additional studies revealed that full calorie restriction (as opposed to restricting one component of the diet) is required for this phenomenon. To our knowledge, Foxo1 is the first transcription factor identified to contribute to altered naïve CD8+ T cell homeostasis during calorie restriction in mice.

Abstract
AIM To outline the impact of the Canterbury, New Zealand (NZ) earthquakes on Christchurch Hospital, and the experiences of emergency nurses during this time. BACKGROUND NZ has experienced earthquakes and aftershocks centred in the Canterbury region of the South Island. The location of these, around and within the major city of Christchurch, was unexpected and associated with previously unknown fault lines. While the highest magnitude quake occurred in September 2010, registering 7.1 on the Richter scale, it was the magnitude 6.3 event on 22 February 2011 which was associated with the greatest injury burden and loss of life. Staff working in the only emergency department in the city were faced with an external emergency while also being directly affected as part of the disaster. SOURCES OF EVIDENCE: This paper developed following interviews with nurses who worked during this period, and draws on literature related to healthcare responses to earthquakes and natural disasters. The establishment of an injury database allowed for an accurate picture to emerge of the injury burden, and each of the authors was present and worked in a clinical capacity during the earthquake. DISCUSSION Nurses played a significant role in the response to the earthquakes and its aftermath. However, little is known regarding the impact of this, either in personal or professional terms. This paper presents an overview of the earthquakes and experiences of nurses working during this time, identifying a range of issues that will benefit from further exploration and research. It seeks to provide a sense of the experiences and the potential meanings that were derived from being part of this 'moment in time'. CONCLUSION Examples of innovations in practice emerged during the earthquake response and a number of recommendations for nursing practice are identified.

Abstract
A panel of reporter gene assays (RGAs) coupled with a single solid phase extraction (SPE) step was developed and used to screen bottled mineral water for the presence of four classes of endocrine disruptors (EDs), oestrogens, androgens, progestagens and glucocorticoids. Fourteen brands of bottled mineral water in triplicate (42 samples) were analysed. Overall, hormonal activity was found in 78% of the samples. Oestrogenic, androgenic, progestagenic and glucocorticoid activity was found in 38%, 38%, 36% and 55% of the samples, respectively at an average concentration of 10 ng/l 17β-estradiol equivalent (EEQ), 26 ng/l testosterone equivalent (TEQ), 123 ng/l progesterone equivalent (PEQ) and 13.5 ng/l hydrocortisone equivalent (HEQ). The level of oestrogenic, androgenic and progestagenic activity observed is not considered a matter of concern for the consumers' health. It is unknown whether the glucocorticoid levels observed are safe. The ED source, long term exposure and mixture effects remain to be investigated.

Abstract
Epidermal growth factor receptors (EGFR) contribute to colonic tumorigenesis in experimental models of colon cancer. We previously showed that EGFR was also required for colonic tumor promotion by Western diet. The goal of this study was to identify EGFR-regulated microRNAs that contribute to diet-promoted colonic tumorigenesis. Murine colonic tumors from Egfr(wt) and hypomorphic Egfr(wa2) mice were screened using micro RNA (miRNA) arrays and miR-143 and miR-145 changes confirmed by Northern, real-time PCR, and in situ analysis. Rodent and human sporadic and ulcerative colitis (UC)-associated colon cancers were examined for miR-143 and miR-145. Effects of EGFR on miR-143 and miR-145 expression were assessed in murine and human colonic cells and their putative targets examined in vitro and in vivo. miR-143 and miR-145 were readily detected in normal colonocytes and comparable in Egfr(wt) and Egfr(wa2) mice. These miRNAs were downregulated in azoxymethane and inflammation-associated colonic tumors from Egfr(wt) mice but upregulated in Egfr(wa2) tumors. They were also reduced in human sporadic and UC colon cancers. EGFR signals suppressed miR-143 and miR-145 in human and murine colonic cells. Transfected miR-143 and miR-145 inhibited HCT116 cell growth in vitro and in vivo and downregulated G(1) regulators, K-Ras, MYC, CCND2, cdk6, and E2F3, putative or established targets of these miRNAs. miRNA targets Ras and MYC were increased in colonic tumors from Egfr(wt) but not Egfr(wa2) mice fed a Western diet. EGFR suppresses miR-143 and miR-145 in murine models of colon cancer. Furthermore, Western diet unmasks the tumor suppressor roles of these EGFR-regulated miRNAs.

Abstract
BACKGROUND A transcription regulatory complex (TRC) that includes Ets1, Ets2, PEA3 and β-catenin/T-cell factors regulates osteopontin (OPN) that is implicated in colorectal cancer (CRC) dissemination. The consistency of OPN transcriptional control between primary CRC and metastases is unclear. This study investigates expression and prognostic significance of the OPN-TRC in primary human CRC and associated colorectal liver metastases (CRLM). METHODS Osteopontin-TRC factors were assayed by digital microscopy in 38 primary CRCs and matched CRLM specimens and assessed against clinical prognosis. RESULTS In primary CRC, OPN expression intensity correlated with that of its co-activators, PEA3 (r=0.600; P<0.01), Ets1 (r=0.552; P<0.01), Ets2 (r=0.521; P<0.01) and had prognostic significance. Osteopontin intensity in primary CRC inversely correlated with the interval between diagnosis and resection of CRLM. Overall OPN intensity was lower in CRLM than primary CRC and correlations with co-activators were weaker, for example, Ets1 (P=0.047), PEA3 (P=0.022) or nonsignificant (Ets2). The ratio of OPN expression in CRLM vs primary CRC had prognostic significance. CONCLUSION This study supports transcriptional control of OPN by known coregulators in both primary and secondary CRC. Weaker associations in CRLM suggest involvement of other unknown factors possibly from the liver microenvironment or resulting from additional genetic or epigenetic changes that drive tumour metastatic capability in OPN transcriptional control.

Abstract
Animal experiments remain essential to understand the fundamental mechanisms underpinning malignancy and to discover improved methods to prevent, diagnose and treat cancer. Excellent standards of animal care are fully consistent with the conduct of high quality cancer research. Here we provide updated guidelines on the welfare and use of animals in cancer research. All experiments should incorporate the 3Rs: replacement, reduction and refinement. Focusing on animal welfare, we present recommendations on all aspects of cancer research, including: study design, statistics and pilot studies; choice of tumour models (e.g., genetically engineered, orthotopic and metastatic); therapy (including drugs and radiation); imaging (covering techniques, anaesthesia and restraint); humane endpoints (including tumour burden and site); and publication of best practice.

Abstract
Animals have been used as experimental models for centuries and their use has enabled researchers to make significant advances in many areas of human health and disease. However, this is not always the case and there are limitations in using animal models as surrogates for humans, which have hampered the development of efficacious therapeutics for some pathologies. Scientific limitations, together with ethical concerns, legislative changes and the current economic climate are driving researchers to look for and develop alternative non-animal research tools. Technological advances in tissue engineering, 'omics' approaches and in silico modelling for example, are enabling scientists to conduct their research without using animals in a broad range of disciplines, including complex multi-system reflexes such as nausea and vomiting.

Abstract
Background All aspects of the heath care sector are being asked to account for their performance. This poses unique challenges for local public health units with their traditional focus on population health and their emphasis on disease prevention, health promotion and protection. Reliance on measures of health status provides an imprecise and partial picture of the performance of a health unit. In 2004 the provincial Institute for Clinical Evaluative Sciences based in Ontario, Canada introduced a public-health specific balanced scorecard framework. We present the conceptual deliberations and decisions undertaken by a health unit while adopting the framework. Discussion Posing, pondering and answering key questions assisted in applying the framework and developing indicators. Questions such as: Who should be involved in developing performance indicators? What level of performance should be measured? Who is the primary intended audience? Where and how do we begin? What types of indicators should populate the health status and determinants quadrant? What types of indicators should populate the resources and services quadrant? What type of indicators should populate the community engagement quadrant? What types of indicators should populate the integration and responsiveness quadrants? Should we try to link the quadrants? What comparators do we use? How do we move from a baseline report card to a continuous quality improvement management tool? Summary An inclusive, participatory process was chosen for defining and creating indicators to populate the four quadrants. Examples of indicators that populate the four quadrants of the scorecard are presented and key decisions are highlighted that facilitated the process.

Abstract
BACKGROUND Extrapancreatic organ dysfunction is the key determinant of mortality in acute pancreatitis (AP). This study aimed to document the frequency and duration of individual organ dysfunction in all fatalities caused by AP in a large, population-based cohort. METHODS All deaths caused by AP in Scotland between 2000 and 2006 inclusive were analysed (n = 1024). RESULTS The median time lapse between the onset of AP and death was 6 days (interquartile range [IQR] 17 days); that between the onset of organ dysfunction and death was 3 days (IQR 7 days). There was no apparent bimodal distribution. The majority of patients had single- (384 patients) or two-system (242 patients) extrapancreatic organ dysfunction. Pulmonary dysfunction was most prevalent (30% of organ-specific entries, 198/660), followed by cardiovascular (18%, 117/660), renal (16%, 108/660), liver (11%, 71/660), gastrointestinal (9%, 59/660), haemorrhage (6%, 38/660), coagulopathy (5%, 31/660) and central nervous system (6%, 38/660) dysfunction. CONCLUSIONS Death in AP occurs early in the disease course. The present findings support the primacy of pulmonary injury as the modal pattern of organ dysfunction in severe AP, with increased frequencies of cardiovascular and renal compromise in fatal AP.

Abstract
BACKGROUND Little is known about inter-facility patient transfers in populations. In 2003, detailed information about inter-facility patient transfers began to be systematically collected in Ontario. METHODOLOGY The authors undertook a descriptive examination of inter-facility patient transfers using a newly created population-based information system. RESULTS Approximately 1,000 inter-facility patient transfers occur in Ontario each day, and every day and a half, the total distance travelled for these transfers equals the distance around the earth's circumference. The annual cost for patient transfers is approximately $283 million. Most common were routine and non-urgent inter-facility patient transfers. Eighty-five thousand patients (24.3% of transferred patients) were transported between healthcare facilities for dialysis appointments, appointments with physicians and return trips home. Patients with circulatory conditions were the most commonly transferred diagnostic group. Although 70% of all transfers were within 25 kilometres, some were for longer distances: for example, those involving pregnant women and newborn babies required travelling a median distance of 40.3 kilometres for continued care. Cardiac patients (54,000 patient transfers per year) travelled a median of 24.2 kilometres to reach a catheterization lab for treatment and further investigation. There was considerable lateral movement between academic health sciences centres (AHSCs). Over 16,000 patients per year (4.7% of all transfers) were transferred from one AHSC to another, predominantly for cardiac care. DISCUSSION Patients in Ontario are often transferred between healthcare facilities. Most transfers are for routine, non-life-threatening reasons, using the Emergency Medical Services (EMS) system. This practice diverts resources from more emergent requests. Although patient transportation is a necessary part of any healthcare system, the results of this study highlight the current demands on a system that was not intended for the volume of inter-facility patient transfers it is supporting. These results call into question the use of sophisticated, highly trained, expensive patient transfer resources to provide routine medical services in Ontario.

Abstract
UNLABELLED This study reports the direct costs related to osteoporosis and hip fractures paid for governmental and private institutions in the Mexican health system and estimates the impact of these entities on Mexico. We conclude that the economic burden due to the direct costs of hip fracture justifies wide-scale prevention programs for osteoporosis (OP). METHODS To estimate the total direct costs of OP and hip fractures in the Mexican Health care system, a sample of governmental and private institutions were studied. Information was gathered through direct questionnaires in 275 OP patients and 218 hip fracture cases. Additionally, a chart review was conducted and experts' opinions obtained to get accurate protocol scenarios for diagnoses and treatment of OP with no fracture. Microcosting and activity-based costing techniques were used to yield unit costs. RESULTS The total direct costs for OP and hip fracture were estimated for 2006 based on the projected annual incidence of hip fractures in Mexico. A total of 22,233 hip fracture cases were estimated for 2006 with a total cost to the healthcare system of US$ 97,058,159 for the acute treatment alone ($4,365.50 per case). We found considerable differences in costs and the way the patients were treated across the different health sectors within the country. CONCLUSION Costs of the acute treatment of hip fractures in Mexico are high and are expected to increase with the predicted increment of life expectancy and the number of elderly in our population.

Abstract
BACKGROUND Osteoporosis is an abnormal reduction in bone mass and bone deterioration leading to increased fracture risk. Risedronate belongs to the bisphosphonate class of drugs which act to inhibit bone resorption by interfering with the activity of osteoclasts. OBJECTIVES To assess the efficacy of residronate in the primary and secondary prevention of osteoporotic fractures in postmenopausal women. SEARCH STRATEGY We searched CENTRAL, MEDLINE and EMBASE. Relevant randomized controlled trials published between 1966 to 2007 were identified. SELECTION CRITERIA Women receiving at least one year of risedronate for postmenopausal osteoporosis were compared to those receiving placebo or concurrent calcium/vitamin D or both. The outcome was fracture incidence. DATA COLLECTION AND ANALYSIS We carried out study selection and data abstraction in duplicate. Study quality was assessed through the reporting of allocation concealment, blinding and withdrawals. Meta-analysis was preformed using relative risks and a >15% relative change was considered clinically important. MAIN RESULTS Seven trials were included in the review representing 14,049 women. Relative (RRR) and absolute (ARR) risk reductions for the 5 mg dose were as follows. Risk estimates for primary prevention were available only for vertebral and non vertebral fractures and showed no statistically significant effect of risedronate on fractures. For secondary prevention, a significant 39% RRR in vertebral fractures (RR 0.61, 95% CI 0.50 to 0.76) with 5% ARR was found. For non-vertebral fractures, a significant 20% RRR (RR 0.80, 95% CI 0.72 to 0.90) with 2% ARR and for hip fractures there was a significant 26% RRR (RR: 0.74, 95% CI 0.59 to 0.94) with a 1% ARR. When primary and secondary prevention studies were combined, the reduction in fractures remained statistically significant for both vertebral (RR 0.63, 0.51 to 0.77) and non vertebral fractures (RR 0.80, 0.72 to 0.90)For adverse events, no statistically significant differences were found in any of the included studies. However, observational data has led to concerns regarding the potential risk for upper gastrointestinal injury and, less commonly, osteonecrosis of the jaw. AUTHORS' CONCLUSIONS At 5 mg/day a statistically significant and clinically important benefit in the secondary prevention of vertebral, non-vertebral and hip fractures was observed, but not for wrist. The level of evidence for secondary prevention is Gold (www.cochranemsk.org) for vertebral and non-vertebral and Silver for hip and wrist. There were no statistically significant reductions in the primary prevention of vertebral and non-vertebral fractures. The level of evidence is Silver.

Abstract
BACKGROUND Osteoporosis is an abnormal reduction in bone mass and bone deterioration leading to increased fracture risk. Alendronate belongs to the bisphosphonate class of drugs, which act to inhibit bone resorption by interfering with the activity of osteoclasts. OBJECTIVES To assess the efficacy of alendronate in the primary and secondary prevention of osteoporotic fractures in postmenopausal women. SEARCH STRATEGY We searched CENTRAL, MEDLINE and EMBASE for relevant randomized controlled trials published between 1966 to 2007. SELECTION CRITERIA Women receiving at least one year of alendronate, for postmenopausal osteoporosis, were compared to those receiving placebo and/or concurrent calcium/vitamin D. The outcome was fracture incidence. DATA COLLECTION AND ANALYSIS We undertook study selection and data abstraction in duplicate. We performed meta-analysis of fracture outcomes using relative risks and a > 15% relative change was considered clinically important. We assessed study quality through reporting of allocation concealment, blinding and withdrawals. MAIN RESULTS Eleven trials representing 12,068 women were included in the review. Relative (RRR) and absolute (ARR) risk reductions for the 10 mg dose were as follows. For vertebral fractures, a significant 45% RRR was found (RR 0.55, 95% CI 0.45 to 0.67). This was significant for both primary prevention, with 45% RRR (RR 0.55, 95% CI 0.38 to 0.80) and 2% ARR, and secondary prevention with 45% RRR (RR 0.55, 95% CI 0.43 to 0.69) and 6% ARR. For non-vertebral fractures, a significant 16% RRR was found (RR 0.84, 95% CI 0.74 to 0.94). This was significant for secondary prevention, with 23% RRR (RR 0.77, 95% CI 0.64 to 0.92) and 2% ARR, but not for primary prevention (RR 0.89, 95% CI 0.76 to 1.04). There was a significant 40% RRR in hip fractures (RR 0.60, 95% CI 0.40 to 0.92), but only secondary prevention was significant with 53% RRR (RR 0.47, 95% CI 0.26 to 0.85) and 1% ARR. The only significance found for wrist was in secondary prevention, with a 50% RRR (RR 0.50 95% CI 0.34 to 0.73) and 2% ARR. For adverse events, we found no statistically significant differences in any included study. However, observational data raise concerns regarding potential risk for upper gastrointestinal injury and, less commonly, osteonecrosis of the jaw. AUTHORS' CONCLUSIONS At 10 mg per day, both clinically important and statistically significant reductions in vertebral, non-vertebral, hip and wrist fractures were observed for secondary prevention ('gold' level evidence, www.cochranemsk.org). We found no statistically significant results for primary prevention, with the exception of vertebral fractures, for which the reduction was clinically important ('gold' level evidence).

Abstract
BACKGROUND Osteoporosis is an abnormal reduction in bone mass and bone deterioration leading to increased fracture risk. Etidronate belongs to the bisphosphonate class of drugs which act to inhibit bone resorption by interfering with the activity of osteoclasts. OBJECTIVES To assess the efficacy of etidronate in the primary and secondary prevention of osteoporotic fractures in postmenopausal women. SEARCH STRATEGY We searched CENTRAL, MEDLINE and EMBASE for relevant randomized controlled trials published between 1966 to 2007. SELECTION CRITERIA Women receiving at least one year of etidronate for postmenopausal osteoporosis were compared to those receiving placebo and/or concurrent calcium/vitamin D. The outcome was fracture incidence. DATA COLLECTION AND ANALYSIS Study selection and data abstraction was done in duplicate. Meta-analysis of fracture outcomes was performed with data presented as relative risks and a relative change greater than 15% was considered clinically important. Study quality was assessed through the reporting of allocation concealment, blinding and withdrawals. MAIN RESULTS Eleven studies representing a total of 1248 patients were included in the review.A significant 41% relative risk reduction (RRR) in vertebral fractures across eight studies (RR 0.59, 95% CI 0.36 to 0.96) was found. The six secondary prevention trials demonstrated a significant RRR of 47% in vertebral fractures (RR 0.53, 95% CI 0.32 to 0.87) and a 5% absolute risk reduction (ARR); compared with the pooled result for the two primary prevention trials (RR 3.03, 95% CI 0.32 to 28.44), which was not significant. There were no statistically significant risk reductions for non-vertebral (RR 0.98, 95% CI 0.68 to 1.42), hip (RR 1.20, 95% CI 0.37 to 3.88) or wrist fractures (RR 0.87, 95% CI: 0.32 to 2.36). For adverse events, no statistically significant differences were found in the included studies. However, observational data has led to concerns regarding potential risk for upper gastrointestinal injury. AUTHORS' CONCLUSIONS Etidronate, at 400 mg per day, demonstrated a statistically significant and clinically important benefit in the secondary prevention of vertebral fractures. No statistically significant reductions in vertebral fractures were observed when it was used for primary prevention. In addition, no statistically significant reductions in non-vertebral, hip, or wrist fractures were found, regardless of whether etidronate was used for primary or secondary prevention. The level of evidence for all outcomes is Silver (www.cochranemsk.org.).

Abstract
BACKGROUND Osteoarthritis (OA) affects a large portion of the population. Low Level Laser Therapy (LLLT) is a light source that generates extremely pure light, of a single wavelength. The effect is not thermal, but rather related to photochemical reactions in the cells. LLLT was introduced as an alternative non-invasive treatment for OA about 30 years ago, but its effectiveness has to be examined more closely, especially in the treatment of OA. OBJECTIVES To assess the effectiveness of class III LLLT for osteoarthritis when irradiation is directed at the osteoarthritic joint capsule. SEARCH STRATEGY Searches were conducted in the following databases: MEDLINE, EMBASE, the Cochrane Musculoskeletal registry, the Rehabilitation and Related Therapies field registry and the Cochrane Controlled Trials Register up to May, 2005. SELECTION CRITERIA Following an a prior protocol, only controlled clinical trials of LLLT for the treatment of patients with a clinical diagnosis of OA were eligible. Abstracts lacking data were excluded unless further data could be obtained from the authors. DATA COLLECTION AND ANALYSIS Two reviewers independently selected trials and extracted data using predetermined forms. A fixed effects model was used throughout for continuous variables, except where heterogeneity existed; in which case, a random effects model was used. Results were analyzed as weighted mean differences (WMD) with 95% confidence intervals (CI), whereas the difference between the treatment and control groups was weighted by the inverse of the variance. Standardized mean differences (SMD) were calculated by dividing the difference between treatment and control by the baseline variance, and were used in the analysis of pain because different scales were used to measure it. Dichotomous outcomes were analyzed with relative risk (RR). MAIN RESULTS Eight trials were included with 233 patients randomized to laser and 172 patients to placebo laser. Treatment duration ranged from two to six weeks. Pain was assessed in seven trials. When the results were pooled from different pain scales used in these seven trials, a statistically significant difference in favor of laser treatment was found with a SMD of -0.28 (95% CI: -0.48 to -0.09). One of these studies also measured pain during movement and found a statistically significant difference in favor of laser treatment with a WMD of -1.16 (95% CI: -2.02 to -0.30). Two studies found significant results for increased knee range of motion. Two others studies found a statistically significant difference in favor of laser treatment for patient-assessed global disease activity with laser compared to placebo (RR 1.70, 95%CI: 1.1. to 2.63). One trial evaluated the effectiveness of laser treatment in temporomandibular joint OA and found a statistically significant difference (WMD 38.69, 95% CI: 29.25 to 48.13) using the change in VAS score to measure pain. One study found a statistically significant difference in favor of laser treatment at the end of treatment and at 4 and 8 weeks post-treatment for morning stiffness. Other outcome measures of joint tenderness and strength did not yield significant differences. AUTHORS' CONCLUSIONS Five trials included in this review showed a statistically significant difference favoring laser treatment when compared to placebo for at least one outcome measure. Three trials did not report beneficial effects. The varying results of these trials may be due to the method of laser application and/or other features of LLLT application. Clinicians and researchers should consistently report the characteristics of LLLT devices and application techniques used. New trials on LLLT should make use of standardized, validated outcomes. There is clearly a need to investigate the effects of different dosages on LLLT effectiveness for OA in future randomized, controlled clinical trials. Also, more studies should be done to investigate the anti-inflammatory action of laser as well as the appropriate parameters needed to achieve an anti-inflammatory effect.
