Abstract
BACKGROUND Caesarean section (CS) is a major abdominal surgery performed usually on a young and healthy population under neuraxial anesthesia with little to no sedation. This creates a distinct surgical experience whereby patients are aware of the surgical process, physical sensations, and their environment. This study aimed to provide an in-depth descriptive assessment of subjective surgical experience during CS under regional anaesthesia. We expected the information gained would enhance our current understanding and better alleviate patient anxiety through informed counselling. METHODS This qualitative descriptive study was conducted at a Canadian academic centre. Twenty patients participated in semi-structured interviews within a week of CS, using an interview guide developed for this study. Patient medical records were reviewed to collect demographic and surgical information. Thematic analysis was conducted using an inductive approach to determine common themes. RESULTS Nine themes were identified. Five themes were identified in the category of surgical sensation and four themes were identified in the category of peri-operative education. CONCLUSIONS Patients commonly experienced pressure and movement sensations at varying intensity, and most did not experience pain. Environmental factors, including sounds and distraction by the newborn, affected perception of surgical sensation. Patients wish to receive pre-operative counselling regarding potential surgical sensations, as well as ongoing communication from their anaesthesiologist. These results can be used to guide informed discussions with patients and direct further investigation in this area.

Abstract
BACKGROUND The prevalence of childhood obesity has been increasing for several decades. Active video games (AVG) may be an effective intervention to help manage this rising health crisis. The aim of this review is to evaluate whether AVG are effective at reducing weight or improving body composition in overweight youths. METHOD Medline, Embase, SportDiscus, ASSIA, CINAHL Plus, CENTRAL, CDSR and PsychINFO databases were searched for studies assessing quantitative or qualitative impact of AVG in overweight adolescents published in English. Three authors screened the results using inclusion/exclusion criteria. RESULTS A total of 12 studies met the inclusion criteria; 11 reported a significant decrease in at least one weight outcome. Results from seven randomized controlled trials were pooled by meta-analysis, which compared with controls subjects in AVG groups demonstrated greater body mass index (BMI) Z-score reduction (mean difference: -0.09 (-0.12, -0.05) I2 = 34%, P < 0.0001). The mean weight reduction (-2.66 Kg (-5.67, +0.35) I2 = 0%, P = 0.08) and BMI (-2.29 (-4.81, +0.22) I2 = 49%, P = 0.07) were greater in AVG groups but results did not reach statistical significance. CONCLUSIONS BMI Z-score was significantly reduced in the AVG group and the majority of included studies reported significant results in at least one weight outcome, suggesting AVG can be used to reduce weight or improve body composition in overweight youths. Further studies investigating the long-term sustainability of this change in body composition are needed.

Abstract
The global workforce crisis significantly impacts how evidence-based treatment is provided to youth with developmental disabilities and co-occurring mental health conditions. Addressing the workforce crisis requires re-examining the long-standing methods of selecting individuals for employment based on academic degrees. This project offers an innovative workforce development option that provides specialized training to staff with advanced education degrees and staff with less education. The participants in this study were employed in a rural area of the USA within the mental health, child welfare, and correctional industries. All participants worked with youth experiencing intellectual disabilities and mental illness. Results indicated that participants improved their knowledge of the population, demonstrated a better understanding of EBPs, and were willing to employ evidence-based approaches regardless of their education or age. Although overall attitudes toward EBPs decreased, diverging attitudes increased, suggesting a need to accommodate treatment strategies when EBP models are unavailable for special populations. Initial knowledge gaps demonstrated by those with a master's degree and those with less education disappeared after the training. This finding supports the application of innovative task-shifting options in mental health, such as diverting more sophisticated care tasks to nonprofessionally trained persons, which can reduce workforce pressure and unmet demand for care. This study demonstrates cost-effective and time-efficient methods of training staff regardless of education by relying less on specific EBP models and more on adaptation.

Abstract
OBJECTIVE Although there is growing interest in medically authorized cannabis for chronic pain, little is known about patients' perspectives. We explored perceptions of people living with chronic pain regarding benefits and concerns surrounding their use of cannabis for therapeutic purposes. SETTING A hospital-based clinic in Hamilton and two community-based interdisciplinary pain clinics in Burlington, Ontario, Canada. METHODS In this qualitative descriptive study, we conducted semi-structured interviews with 13 people living with chronic pain who used cannabis therapeutically, living in Ontario, Canada. We used thematic analysis, with data collection, coding, and analysis occurring concurrently. RESULTS People living with chronic pain reported important benefits associated with use of cannabis for therapeutic purposes, including reduced pain, improved functionality, and less risk of harms compared to prescription opioids. Most patients also acknowledged harms, such as grogginess and coughing, and there was considerable variability in patient experiences. Financial costs and stigma were identified as important barriers to use of cannabis. CONCLUSION Evidence-based guidance that incorporates patients' values and preferences may be helpful to inform the role of cannabis in the management of chronic pain.

Abstract
Only a small proportion of COVID-19 patients in Canada have been recruited into clinical research studies. One reason is that few community intensive care units (ICUs) in Canada participate in research. The objective of this study was to examine the motivating factors, barriers and facilitators to research participation amongst Canadian community ICU stakeholders. A cross-sectional online survey was distributed between May and November 2020. The survey focused on 6 domains: participant demographics, ICU characteristics, ICU research infrastructure, motivating factors, perceived barriers, and perceived facilitators. Responses were received from 73 community ICU stakeholders, representing 18 ICUs. 7/18 ICUs had a clinical research program. Participants rated their interest in pandemic research at a mean of 5.2 (Standard Deviation [SD] = 1.9) on a 7-point Likert scale from ‘not interested’ to ‘very interested’. The strongest motivating factor for research participation was the belief that research improves clinical care and outcomes. The most significant facilitators of research involvement were the availability of an experienced research coordinator and dedicated external funding to cover start-up costs, while the most significant barriers to research involvement were a lack of start-up funding for a research coordinator and a lack of ICU research experience. Canadian Community ICU stakeholders are interested in participating in pandemic research but lack basic infrastructure, research personnel, research experience and start-up funding. Evolution of a research support model at community hospitals, where most patients receive acute care, may increase research participation and improve the generalizability of funded research in Canada.

Abstract
Inappropriate use of antibiotics is among the key drivers of antimicrobial resistance (AMR). Antibiotic use in Northern Ireland (NI) is the highest in the UK and approximately 80% is prescribed in primary care. Little information however exists about the patient and prescriber factors driving this. We described the trend in NI primary care total antibiotic prescribing 2010–2019 and conducted a cross-sectional study using a random sample of individuals registered with an NI GP on 1st January 2019. We used multilevel logistic regression to examine how sociodemographic factors and urinary catheter use was associated with the likelihood of being prescribed an antibiotic during 2019, adjusting for clustering at GP practice and GP federation levels. Finite mixture modelling (FMM) was conducted to determine the association between the aforementioned risk factors and quantity of antibiotic prescribed (defined daily doses). The association between age and antibiotic prescription differed by gender. Compared to males 41–50 years, adjusted odds of prescription were higher for males aged 0–10, 11–20 and 51 + years, and females of any age. Catheter use was strongly associated with antibiotic prescription (aOR = 6.82, 95% CI 2.50–18.64). Socioeconomic deprivation and urban/rural settlement were not associated in the multilevel logistic analysis. GP practices and federations accounted for 1.24% and 0.12% of the variation in antibiotic prescribing respectively. FMM showed associations between larger quantities of antibiotics and being older, male and having a catheter. This work described the profile of individuals most likely to receive an antibiotic prescription in NI primary care and identified GP practice as a source of variation; suggesting an opportunity for reduction from effective interventions targeted at both individuals and general practices.

Abstract
INTRODUCTION Chronic pelvic pain (CPP) is a significant issue, and approximately 14% of women experience CPP once in their life-time. While interdisciplinary pain management is considered the gold standard of treatment, few programs offer this type of treatment in Canada. The aims of this paper were to: 1) describe the development of an interdisciplinary CPP program; and 2) demonstrate changes in patient-related outcomes after attending an interdisciplinary CPP program. METHODS Referrals were received from community urologists and obstetricians/gynecologists, and pain physicians at the Michael G. DeGroote Pain Clinic. Patients attended an orientation session, completed an interdisciplinary assessment, and if appropriate, attended an eight-day interdisciplinary CPP program. Each day consisted of group-based pelvic floor physiotherapy, psychoeducation, goal-setting, cognitive behavioral therapy, and mindfulness. Psychometric questionnaires were completed pre- and post-program by patients, and paired sample t-tests were used to evaluate the changes in patient-related outcomes after attending the program. RESULTS Thirty-seven female patients completed the program, and results demonstrate that the CPP program was associated with significant improvements in impact of pelvic pain on quality of life, readiness for change, and pain-related self-efficacy, as well as decreases in pain catastrophizing and fear of pain/re-injury. CONCLUSIONS CPP is a complex condition that requires interdisciplinary management and care. The results of this study demonstrate the short-term benefits of an interdisciplinary CPP program, highlight the unique needs of women with CPP, and implicate multiple factors for programming and treatment.

Abstract
IMPORTANCE Evidence regarding corticosteroid use for severe coronavirus disease 2019 (COVID-19) is limited. OBJECTIVE To determine whether hydrocortisone improves outcome for patients with severe COVID-19. DESIGN, SETTING, AND PARTICIPANTS An ongoing adaptive platform trial testing multiple interventions within multiple therapeutic domains, for example, antiviral agents, corticosteroids, or immunoglobulin. Between March 9 and June 17, 2020, 614 adult patients with suspected or confirmed COVID-19 were enrolled and randomized within at least 1 domain following admission to an intensive care unit (ICU) for respiratory or cardiovascular organ support at 121 sites in 8 countries. Of these, 403 were randomized to open-label interventions within the corticosteroid domain. The domain was halted after results from another trial were released. Follow-up ended August 12, 2020. INTERVENTIONS The corticosteroid domain randomized participants to a fixed 7-day course of intravenous hydrocortisone (50 mg or 100 mg every 6 hours) (n = 143), a shock-dependent course (50 mg every 6 hours when shock was clinically evident) (n = 152), or no hydrocortisone (n = 108). MAIN OUTCOMES AND MEASURES The primary end point was organ support-free days (days alive and free of ICU-based respiratory or cardiovascular support) within 21 days, where patients who died were assigned -1 day. The primary analysis was a bayesian cumulative logistic model that included all patients enrolled with severe COVID-19, adjusting for age, sex, site, region, time, assignment to interventions within other domains, and domain and intervention eligibility. Superiority was defined as the posterior probability of an odds ratio greater than 1 (threshold for trial conclusion of superiority >99%). RESULTS After excluding 19 participants who withdrew consent, there were 384 patients (mean age, 60 years; 29% female) randomized to the fixed-dose (n = 137), shock-dependent (n = 146), and no (n = 101) hydrocortisone groups; 379 (99%) completed the study and were included in the analysis. The mean age for the 3 groups ranged between 59.5 and 60.4 years; most patients were male (range, 70.6%-71.5%); mean body mass index ranged between 29.7 and 30.9; and patients receiving mechanical ventilation ranged between 50.0% and 63.5%. For the fixed-dose, shock-dependent, and no hydrocortisone groups, respectively, the median organ support-free days were 0 (IQR, -1 to 15), 0 (IQR, -1 to 13), and 0 (-1 to 11) days (composed of 30%, 26%, and 33% mortality rates and 11.5, 9.5, and 6 median organ support-free days among survivors). The median adjusted odds ratio and bayesian probability of superiority were 1.43 (95% credible interval, 0.91-2.27) and 93% for fixed-dose hydrocortisone, respectively, and were 1.22 (95% credible interval, 0.76-1.94) and 80% for shock-dependent hydrocortisone compared with no hydrocortisone. Serious adverse events were reported in 4 (3%), 5 (3%), and 1 (1%) patients in the fixed-dose, shock-dependent, and no hydrocortisone groups, respectively. CONCLUSIONS AND RELEVANCE Among patients with severe COVID-19, treatment with a 7-day fixed-dose course of hydrocortisone or shock-dependent dosing of hydrocortisone, compared with no hydrocortisone, resulted in 93% and 80% probabilities of superiority with regard to the odds of improvement in organ support-free days within 21 days. However, the trial was stopped early and no treatment strategy met prespecified criteria for statistical superiority, precluding definitive conclusions. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02735707.

Abstract
IMPORTANCE Evidence regarding corticosteroid use for severe coronavirus disease 2019 (COVID-19) is limited. OBJECTIVE To determine whether hydrocortisone improves outcome for patients with severe COVID-19. DESIGN, SETTING, AND PARTICIPANTS An ongoing adaptive platform trial testing multiple interventions within multiple therapeutic domains, for example, antiviral agents, corticosteroids, or immunoglobulin. Between March 9 and June 17, 2020, 614 adult patients with suspected or confirmed COVID-19 were enrolled and randomized within at least 1 domain following admission to an intensive care unit (ICU) for respiratory or cardiovascular organ support at 121 sites in 8 countries. Of these, 403 were randomized to open-label interventions within the corticosteroid domain. The domain was halted after results from another trial were released. Follow-up ended August 12, 2020. INTERVENTIONS The corticosteroid domain randomized participants to a fixed 7-day course of intravenous hydrocortisone (50 mg or 100 mg every 6 hours) (n = 143), a shock-dependent course (50 mg every 6 hours when shock was clinically evident) (n = 152), or no hydrocortisone (n = 108). MAIN OUTCOMES AND MEASURES The primary end point was organ support-free days (days alive and free of ICU-based respiratory or cardiovascular support) within 21 days, where patients who died were assigned -1 day. The primary analysis was a bayesian cumulative logistic model that included all patients enrolled with severe COVID-19, adjusting for age, sex, site, region, time, assignment to interventions within other domains, and domain and intervention eligibility. Superiority was defined as the posterior probability of an odds ratio greater than 1 (threshold for trial conclusion of superiority >99%). RESULTS After excluding 19 participants who withdrew consent, there were 384 patients (mean age, 60 years; 29% female) randomized to the fixed-dose (n = 137), shock-dependent (n = 146), and no (n = 101) hydrocortisone groups; 379 (99%) completed the study and were included in the analysis. The mean age for the 3 groups ranged between 59.5 and 60.4 years; most patients were male (range, 70.6%-71.5%); mean body mass index ranged between 29.7 and 30.9; and patients receiving mechanical ventilation ranged between 50.0% and 63.5%. For the fixed-dose, shock-dependent, and no hydrocortisone groups, respectively, the median organ support-free days were 0 (IQR, -1 to 15), 0 (IQR, -1 to 13), and 0 (-1 to 11) days (composed of 30%, 26%, and 33% mortality rates and 11.5, 9.5, and 6 median organ support-free days among survivors). The median adjusted odds ratio and bayesian probability of superiority were 1.43 (95% credible interval, 0.91-2.27) and 93% for fixed-dose hydrocortisone, respectively, and were 1.22 (95% credible interval, 0.76-1.94) and 80% for shock-dependent hydrocortisone compared with no hydrocortisone. Serious adverse events were reported in 4 (3%), 5 (3%), and 1 (1%) patients in the fixed-dose, shock-dependent, and no hydrocortisone groups, respectively. CONCLUSIONS AND RELEVANCE Among patients with severe COVID-19, treatment with a 7-day fixed-dose course of hydrocortisone or shock-dependent dosing of hydrocortisone, compared with no hydrocortisone, resulted in 93% and 80% probabilities of superiority with regard to the odds of improvement in organ support-free days within 21 days. However, the trial was stopped early and no treatment strategy met prespecified criteria for statistical superiority, precluding definitive conclusions.

Abstract
Objective: The primary objectives of this pre-post session study, was to evaluate the impact of a pharmacist-led education session on the perceived benefits and safety of cannabis among patients with chronic pain, as well as determine the influence of pharmacist education on the selection of safer cannabis products and dosage forms for medical use among patients. Methods: A retrospective analysis of completed pre-post session questionnaires was conducted among chronic pain patients attending a mandatory education session led by a pharmacist, prior to being authorized cannabis in clinic. All questionnaire data was analyzed using SPSS v. 25. Demographic and sample characteristics were reviewed using univariate analyses. Chi-Square tests were employed to determine if the group-based education significantly affected knowledge, perception of efficacy and safety of cannabis. Results: Of the 260 session participants, 203 completed pre-post session questionnaires. After the session, a majority of current cannabis users (33.8%) and cannabis naïve/past users (56.9%) reported they would use a low THC product in the future, and a majority of current users (54.5%) would use a high CBD product in the future. After education, participants were more likely to report cannabis as having the potential for addiction (chi-square =42.6, p <0.0001) and harm (chi-square =34.0, p <0.0001). Conclusions: Pharmacist counselling and education has the potential to influence patient selection and use of cannabis, from more harmful to safer products, as well as moderate the potential perceived benefits of use.

Abstract
Purpose Children who are deaf and hard of hearing (DHH) face a wide array of issues that can impact their mental health and well-being. This study aimed to explore the role of schools and classroom teachers in supporting the mental health and well-being of DHH children. Method A qualitative study comprising telephone and semistructured interviews with 12 mainstream school classroom teachers who directly support the education and well-being of DHH children was conducted. Thematic analysis was used to analyze the data. Result Classroom teachers indicated they play an important role in supporting the mental health and well-being of DHH children but identified a range of constraints to providing this support. Four themes were identified: (a) "culture of professional practice," (b) "operationalized practice," (c) "constraints to practice," and (d) "solutions for constraints." Conclusions Classroom teachers play an important role in supporting the mental health and well-being of DHH children but face several constraints in their practice, including limited training and awareness and access to resources. While further research is needed, this study suggests that classroom resources and teacher professional development are needed to enhance classroom teachers' understanding of how to support the mental health and well-being of DHH children.

Abstract
In Northern Ireland there are concerns about candidaemia, with rates higher than those reported in England and Wales. Our aim was to explore the epidemiology of candidaemia during a 10 year period and the clinical management upon suspicion of cases during a one year enhanced investigation in Northern Ireland.Candidaemia reports to the Public Health Agency were validated during 2002-2011 and used to examine incidence and antifungal sensitivity trends (during 2007-2011). A clinical proforma was used to collate information for all patients with candidaemia in 2011.The majority (96%) of isolates were captured through voluntary laboratory reporting. There was a year-on-year increase in candidaemia from 2002-2011, from 80 to 131 episodes (incidence rate ratio 1.09 95% CI 1.05-1.13). Rates were highest in males under 1 year and over 75 years. 83/98 (85%) of case notes were available from candidaemia patients during 2011. The most prevalent risk factors were patients on total parenteral nutrition (26 people, 31.3%), surgery in the two months prior to the candidaemia (25 people, 30.1%), significant steroid use in the previous 3 months (24 people, 28.9%) and active neoplastic disease (23 people, 27.7%),This study confirmed an increase in candidaemia rates over time, with the observed incidence in 2011 higher than England and Wales. We identified areas for improvement around the clinical management of candidaemia. We recommend raising the awareness of guidelines for fundoscopy, echocardiography and central venous catheter removal.

Abstract
Background: One in five Canadians experience chronic pain, and interdisciplinary pain programs are well established as the gold standard of treatment. However, not all patients are ready to engage in interdisciplinary treatment for chronic pain. Aims: The aims of this study were to (1) first demonstrate changes in patient-related outcomes after attending a publicly funded 8-week interdisciplinary pain program and (2) evaluate pain-related predictors of readiness for change. Methods: The institution's research ethics board approved this study. One hundred twenty-nine patients completed questionnaires on the first and last day of attending the program. Paired sample t-tests were utilized to evaluate the changes in patient-related outcomes after attending the program, and linear regressions were utilized to evaluate pain-related predictors of the stages of change. Results: Postprogram, there were significant decreases in pain-related interference, fear of pain/re-injury, pain catastrophizing, and symptoms of stress, depression, and anxiety and a significant increase in wellness-focused coping and self-efficacy. Postprogram, patients also demonstrated lower scores in precontemplation and contemplation and higher scores in action and maintenance stages of readiness for change. In predicting precontemplation, fear of pain/re-injury was the sole predictor, and self-efficacy was the sole predictor of the contemplation, action, and maintenance stages. Conclusion: These results demonstrate the short-term benefits of an 8-week interdisciplinary pain program. It is suggested that preprogram interventions targeting kinesophobia for individuals who are precontemplative and self-efficacy for others may be important to facilitate patient engagement.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
OBJECTIVES To train and compare machine-learning algorithms with traditional regression analysis for the prediction of early biochemical recurrence after robot-assisted prostatectomy. PATIENTS AND METHODS A prospectively collected dataset of 338 patients who underwent robot-assisted prostatectomy for localized prostate cancer was examined. We used three supervised machine-learning algorithms and 19 different training variables (demographic, clinical, imaging and operative data) in a hypothesis-free manner to build models that could predict patients with biochemical recurrence at 1 year. We also performed traditional Cox regression analysis for comparison. RESULTS K-nearest neighbour, logistic regression and random forest classifier were used as machine-learning models. Classic Cox regression analysis had an area under the curve (AUC) of 0.865 for the prediction of biochemical recurrence. All three of our machine-learning models (K-nearest neighbour (AUC 0.903), random forest tree (AUC 0.924) and logistic regression (AUC 0.940) outperformed the conventional statistical regression model. Accuracy prediction scores for K-nearest neighbour, random forest tree and logistic regression were 0.976, 0.953 and 0.976, respectively. CONCLUSIONS Machine-learning techniques can produce accurate disease predictability better that traditional statistical regression. These tools may prove clinically useful for the automated prediction of patients who develop early biochemical recurrence after robot-assisted prostatectomy. For these patients, appropriate individualized treatment options can improve outcomes and quality of life.

Abstract
In 2010, 2.5 million people sustained a traumatic brain injury (TBI), with an estimated 75 per cent being mild TBI. Mild TBI is defined as a Glasgow Coma Scale (GCS) of 13 to 15. Based on recent data and our institutional experience, we hypothesized that mild TBI patients, including patients on aspirin, could be safely managed by trauma surgeons without neurosurgical consultation. Trauma patients admitted to a single Level I trauma center from June 2014 through July 2015 aged 18 years or older were evaluated. Patients with a GCS ≥14, regardless of intoxication, with an epidural or subdural hematoma ≤4 mm, trace or small subarachnoid hemorrhage, and/or nondisplaced skull fracture were prospectively enrolled. The primary outcomes were needed for neurosurgical consultation and intervention. Secondary outcomes included readmission rate and neurologic morbidity and mortality rate. Of 1341 trauma admits, 77 were enrolled. No patients required neurosurgical intervention. Only 1/75 (1.3%) patients required neurosurgical consultation. Outpatient follow-up was achieved with 75/77 (97.4%) patients. No mortalities, major neurologic morbidities, or readmissions were observed (95% confidence interval 0-4%). None of the 21 patients on aspirin required neurosurgical intervention and only 1/21 (4.8%) patients required neurosurgical consultation with no mortalities observed at follow-up. Management of mild TBI can be safely accomplished by trauma surgeons without routine neurosurgical consultation. Larger multicenter prospective studies are required to evaluate our finding that this also may be safe in patients taking aspirin.

Abstract
Background : In Europe, over 70% of the population live in urban areas (UAs). Most international comparative health research is done using national level data, as reliable and comparable urban data are often unavailable or difficult to access. This study aims to investigate whether population health is different in UAs compared with their corresponding countries. : Routinely available health-related data were collected by the EURO-URHIS 2 project, for 10 European countries and for 24 UAs within those countries. National and UA level data for 11 health indicators were compared through the calculation of relative difference, and geographical patterns within Europe were investigated using the Mann Whitney U test. Linear regression modelling was used to adjust for population density, gross domestic product and urbanicity. : In general, the urban population in Eastern Europe is less healthy than the Western European urban population. However, people in Eastern Europe have significantly better broad health outcomes in UAs as compared with the corresponding country as a whole, whereas people in Western Europe have generally worse broader health outcomes in UAs. : For most European countries and UAs that were investigated, the national level health status data does not correspond with the health status at UA level. In order to identify health problems in UAs and to provide information for local health policy, health monitoring and international benchmarking should also be conducted at the local level.

Abstract
This chapter deconstructs the process of angiogenesis into its component parts in order to provide simple assays to measure discrete endothelial cell functions. The techniques described will be suitable for studying stimulators and/or inhibitors of angiogenesis and determining which aspect of the process is modulated. The assays are designed to be robust and straightforward, using human umbilical vein endothelial cells, but with an option to use other sources such as microvascular endothelial cells from various tissues or lymphatic endothelial cells. It must be appreciated that such reductionist approaches cannot cover the complexity of the angiogenic process as a whole, incorporating as it does a myriad of positive and negative signals, three-dimensional interactions with host tissues and many accessory cells including fibroblasts, macrophages, pericytes and platelets. The extent to which in vitro assays predict physiological or pathological processes in vivo (e.g., wound healing, tumor angiogenesis) or surrogate techniques such as the use of Matrigel™ plugs, sponge implants, corneal assays etc remains to be determined.

Abstract
Abstract
The current 2D methods for cancer drug discovery have had some difficulty in identifying potential drug candidates that can be used for clinical testing. To overcome this challenge, there has been an increase in research of 3D tissue culture that facilitated the development of new in-vitro tumor model assays. Traditional 2D and 3D analysis method relied heavily on visual observation using microscopy. However, the method is time-consuming and has high variations. Automated plate-based imaging cytometer can be employed to rapidly analyze and characterize 3D tumor spheroids, which can be used to generate both quantitative and qualitative results. In this work, we demonstrate a novel 3D tumor spheroid analysis method using the Celigo imaging cytometer for spheroid counting, size analysis, tumor migration and invasion, tumor viability, and dose response of drug induced/inhibited tumor growth. The plate-based imaging cytometer utilizes bright-field and three fluorescence channels (Blue, Green, and Red) for multi-channel analysis. By utilizing the F theta lens technology, uniform bright-field image is captured for more accurate counting of the entire well. In addition, Celigo analysis software is used to report numerous parameters allowing detailed spheroid characterization. In addition to direct spheroid counting in the well, the use of specific fluorescent dyes and probes allow the user to define viable and hypoxic areas within spheroids and monitor migration and invasion on or into supporting cells and/or tissues. The results showed that Celigo imaging cytometer can accurately count and measure spheroid sizes in response to drug induction. Furthermore, tumor migration and invasion were clearly observed and quantified in the captured images. By utilizing the 3D spheroid imaging cytometry method, researchers can quickly characterize and quantify tumor spheroids, which can improve the efficiency of identification of potential cancer drug candidates.

Abstract
We report an outbreak of four confirmed cases of invasive pneumococcal disease (IPD) in individuals occupationally exposed to welding fumes, at a Belfast shipyard (Northern Ireland). All cases were hospitalised. A high-risk sub-group of 679 workers has been targeted for antibiotic prophylaxis and pneumococcal vaccination. Physicians and public health institutions outside Northern Ireland should be alert to individuals presenting with pneumonia or IPD and recent links to the shipyard, to facilitate early assessment and treatment.

Abstract
The morbidity and mortality associated with Clostridium difficile ribotype 078 were examined by comparison with other known outbreak strains. A healthcare interaction within eight weeks of a positive specimen significantly increased the likelihood of ribotype 078 compared with ribotype 027. Individuals with ribotype 078 also tended to come from community sources, have a hospital stay post specimen similar to ribotype 027 and a lower 30-day mortality, but these differences were not statistically significant. This study generates several hypotheses and a methodological platform to explore this unique profile.

Abstract
Background There is overwhelming evidence that in vitro three-dimensional tumor cell cultures more accurately reflect the complex in vivo microenvironment than simple two-dimensional cell monolayers, not least with respect to gene expression profiles, signaling pathway activity and drug sensitivity. However, most currently available three-dimensional techniques are time consuming and/or lack reproducibility; thus standardized and rapid protocols are urgently needed. Results To address this requirement, we have developed a versatile toolkit of reproducible three-dimensional tumor spheroid models for dynamic, automated, quantitative imaging and analysis that are compatible with routine high-throughput preclinical studies. Not only do these microplate methods measure three-dimensional tumor growth, but they have also been significantly enhanced to facilitate a range of functional assays exemplifying additional key hallmarks of cancer, namely cell motility and matrix invasion. Moreover, mutual tissue invasion and angiogenesis is accommodated by coculturing tumor spheroids with murine embryoid bodies within which angiogenic differentiation occurs. Highly malignant human tumor cells were selected to exemplify therapeutic effects of three specific molecularly-targeted agents: PI-103 (phosphatidylinositol-3-kinase (PI3K)-mammalian target of rapamycin (mTOR) inhibitor), 17-N-allylamino-17-demethoxygeldanamycin (17-AAG) (heat shock protein 90 (HSP90) inhibitor) and CCT130234 (in-house phospholipase C (PLC)γ inhibitor). Fully automated analysis using a Celigo cytometer was validated for tumor spheroid growth and invasion against standard image analysis techniques, with excellent reproducibility and significantly increased throughput. In addition, we discovered key differential sensitivities to targeted agents between two-dimensional and three-dimensional cultures, and also demonstrated enhanced potency of some agents against cell migration/invasion compared with proliferation, suggesting their preferential utility in metastatic disease. Conclusions We have established and validated a suite of highly reproducible tumor microplate three-dimensional functional assays to enhance the biological relevance of early preclinical cancer studies. We believe these assays will increase the translational predictive value of in vitro drug evaluation studies and reduce the need for in vivo studies by more effective triaging of compounds.

Abstract
Voltage-gated sodium channel (VGSC) activity has previously been reported in endothelial cells (ECs). However, the exact isoforms of VGSCs present, their mode(s) of action, and potential role(s) in angiogenesis have not been investigated. The main aims of this study were to determine the role of VGSC activity in angiogenic functions and to elucidate the potentially associated signaling mechanisms using human umbilical vein endothelial cells (HUVECs) as a model system. Real-time PCR showed that the primary functional VGSC α- and β-subunit isoforms in HUVECs were Nav1.5, Nav1.7, VGSCβ1, and VGSCβ3. Western blots verified that VGSCα proteins were expressed in HUVECs, and immunohistochemistry revealed VGSCα expression in mouse aortic ECs in vivo. Electrophysiological recordings showed that the channels were functional and suppressed by tetrodotoxin (TTX). VGSC activity modulated the following angiogenic properties of HUVECs: VEGF-induced proliferation or chemotaxis, tubular differentiation, and substrate adhesion. Interestingly, different aspects of angiogenesis were controlled by the different VGSC isoforms based on TTX sensitivity and effects of siRNA-mediated gene silencing. Additionally, we show for the first time that TTX-resistant (TTX-R) VGSCs (Nav1.5) potentiate VEGF-induced ERK1/2 activation through the PKCα-B-RAF signaling axis. We postulate that this potentiation occurs through modulation of VEGF-induced HUVEC depolarization and [Ca(2+)](i). We conclude that VGSCs regulate multiple angiogenic functions and VEGF signaling in HUVECs. Our results imply that targeting VGSC expression/activity could be a novel strategy for controlling angiogenesis.

Abstract
PURPOSE Policy recommendations specify how academic medical centers should manage clinical conflicts of interest (CCOIs), including gifts and payments to physicians from pharmaceutical companies. However, no reliable data exist on the extent to which schools have policies to manage CCOIs. The authors sought to determine the extent and strength of medical schools' CCOI policies. METHOD A survey asked compliance officers at 125 MD-granting medical schools in the United States to indicate whether their institutions had policies covering 11 areas of CCOI and to provide copies of relevant policies. Policies were scored as 0 (no policy), 1 (permissive), 2 (moderate), or 3 (stringent), based on published recommendations. Each school's scores were averaged to create a measure of overall policy strength. The authors also collected information on schools' public/private status, hospital ownership/affiliation, and NIH funding to determine whether these characteristics were associated with differences in policy strength. RESULTS A representative sample of 77 of 125 (62%) medical schools responded between October 2007 and December 2008. Absence of policy was the most frequent finding in 7 of 11 CCOI areas. The mean score for overall policy strength was 1.2. Greater NIH funding was associated with stronger policies in 9 areas. CONCLUSIONS This analysis provides a comprehensive overview of medical schools' CCOI policies. Wider adoption of CCOI policies is crucial to eliminate undue industry influence in clinical care and to preserve public trust in the medical profession. The authors close with a consideration of why so few medical schools have implemented strong policies.

Abstract
HYPOTHESIS We hypothesized that patient factors, injury patterns, and therapeutic interventions influence outcomes among older patients incurring traumatic chest injuries. DESIGN Patients older than 50 years with at least 1 rib fracture (RF) were retrospectively studied, including institutional data, patient data, clinical interventions, and complications. Univariable and multivariable analyses were performed. SETTING Eight trauma centers. PATIENTS A total of 1621 patients. MAIN OUTCOME MEASURE Survival. RESULTS Patient data collected include the following: age (mean, 70.1 years), number of RFs (mean, 3.7), Abbreviated Injury Scale chest score (mean, 2.7), Injury Severity Score (mean, 11.7), and mortality (overall, 4.6%). On univariable analysis, increased mortality was associated with admission to high-volume trauma centers and level I centers, preexisting coronary artery disease or congestive heart failure, intubation or development of pneumonia, and increasing age, Injury Severity Score, and number of RFs. On multivariable analysis, strongest predictors of mortality were admission to high-volume trauma centers, preexisting congestive heart failure, intubation, and increasing age and Injury Severity Score. Using this predictive model, tracheostomy and patient-controlled analgesia had protective effects on survival. CONCLUSIONS In a large regional trauma cooperative, increasing age and Injury Severity Score were independent predictors of survival among older patients incurring traumatic RFs. Admission to high-volume trauma centers, preexisting congestive heart failure, and intubation added to mortality. Therapies associated with improved survival were patient-controlled analgesia and tracheostomy. Further regional cooperation should allow development of standard care practices for these challenging patients.

Abstract
INTRODUCTION Following the withdrawal of acute medical services from rural Angus, a rapid-access Neurovascular (TIA) Clinic was established at Stracathro Hospital in December 2003. Referral protocols were agreed with Angus Primary Care. We measured the performance of this clinic over its first two years against national standards outlined by Quality Improvement Scotland (2005). METHODS In a retrospective study between 1st December 2003 and 30th November 2005, patient demographics, waiting times, investigation results, diagnoses, and secondary prevention issues were analysed. Challenges presented by a rural setting were also examined, RESULTS By November 2005, from a total of 355 patients, 79% were seen within 7 days and 98% within 14 days of clinic referral. Pre-clinic bloods were increasingly done in general practice. All patients had CT head and carotid NIVA scans performed on the day of clinic attendance. A high positive diagnostic yield from CT scanning was obtained in the first year of the clinic, and a significant proportion of patients had new secondary drug prevention treatment recommended. Organisational and transport difficulties were addressed and overcome. DISCUSSION Developing a rapid-access neurovascular clinic in a rural setting is achievable, and waiting times approaching national standard targets are possible. A TIA clinic can identify rapidly those with cerebrovascular disease, allowing commencement of appropriate secondary prevention therapy.

Employees with limited education may be excluded from advanced training due to assumptions that they might not learn rapidly. However, preparatory training may be able to overcome missing experience in education. The purpose of this study was to test the hypothesis that computer-based training (CBT) in supervisor skills of Latino agricultural workers would improve subsequent performance in a workshop designed to teach supervisor skills. Ten men born and educated in Mexico participated in the study; all spoke Spanish, the language of the training. Five participants (mean 6.4 years of education) completed supervisor skills CBT, and five participants (mean 8.2 years of education) completed hazard communication (HazCom) CBT as a control condition. Following the CBT, all participants completed a two-day face-to-face workshop on supervisory skills conducted by an experienced behavior management consultant. Although the groups did not differ in their knowledge scores on a multiple-choice test before the face-to-face workshop, after the workshop the HazCom group had a mean test score of 51.2% (SD = 8.7) while the supervisor group had a higher mean test score of 65.2% (SD = 14.3). The difference was marginally significant by a t-test (p = 0.052), and the effect size was large (d = 1.16). The results suggest that computer-based training in supervisor skills can be effective in preparing participants with limited education to learn supervisor skills from a face-to-face workshop. This result suggests that limited educational attainment is not a barrier to learning the complex knowledge required to supervise employees, that pre-training may improve learning in a workshop format, and that training may be presented effectively in a computer-based format to employees with limited education.

Abstract
This chapter covers the breakdown of the process of angiogenesis into simple assays to measure discrete endothelial cell functions. The techniques described are suitable for studying stimulators or inhibitors of angiogenesis and determining which aspect of the process is modulated. The procedures outlined are robust and straightforward but cannot cover the complexity of the angiogenic process as a whole, incorporating as it does myriad positive and negative signals, three-dimensional interactions with host tissues and many accessory cells, including fibroblasts, macrophages, pericytes, and platelets. The extent to which in vitro assays predict responses in vivo (e.g., wound healing, tumor angiogenesis, or surrogate techniques such as Matrigel plugs, sponge implants, corneal assays, etc.) remains to be determined.

Abstract
Phospholipase C-gamma (PLC-gamma) has been identified as a possible biological target for anticancer drug therapy but suitable inhibitors are lacking. Therefore, in order to identify active compounds (hits) virtual high throughput screening was performed. The crystal structure of the PLC-delta isoform was used as a model docking scaffold since no crystallographic data are available on its gamma counterpart. A pilot screen was performed using approximately 9.2x10(4) compounds, where the robustness of the methodology was tested. This was followed by the main screening effort where approximately 4.4x10(5) compounds were used. In both cases, plausible compounds were identified (virtual hits) and a selection of these was experimentally tested. The most potent compounds were in the single digit micro-molar range as determined from the biochemical (Flashplate) assay. This translated into approximately 15 microM in a functional assay in cells. About 30% of the virtual hits showed activity against PLC-gamma (IC(50)<50 microM).

Abstract
We describe the biological properties of NVP-AUY922, a novel resorcinylic isoxazole amide heat shock protein 90 (HSP90) inhibitor. NVP-AUY922 potently inhibits HSP90 (K(d) = 1.7 nmol/L) and proliferation of human tumor cells with GI(50) values of approximately 2 to 40 nmol/L, inducing G(1)-G(2) arrest and apoptosis. Activity is independent of NQO1/DT-diaphorase, maintained in drug-resistant cells and under hypoxic conditions. The molecular signature of HSP90 inhibition, comprising induced HSP72 and depleted client proteins, was readily demonstrable. NVP-AUY922 was glucuronidated less than previously described isoxazoles, yielding higher drug levels in human cancer cells and xenografts. Daily dosing of NVP-AUY922 (50 mg/kg i.p. or i.v.) to athymic mice generated peak tumor levels at least 100-fold above cellular GI(50). This produced statistically significant growth inhibition and/or regressions in human tumor xenografts with diverse oncogenic profiles: BT474 breast tumor treated/control, 21%; A2780 ovarian, 11%; U87MG glioblastoma, 7%; PC3 prostate, 37%; and WM266.4 melanoma, 31%. Therapeutic effects were concordant with changes in pharmacodynamic markers, including induction of HSP72 and depletion of ERBB2, CRAF, cyclin-dependent kinase 4, phospho-AKT/total AKT, and hypoxia-inducible factor-1alpha, determined by Western blot, electrochemiluminescent immunoassay, or immunohistochemistry. NVP-AUY922 also significantly inhibited tumor cell chemotaxis/invasion in vitro, WM266.4 melanoma lung metastases, and lymphatic metastases from orthotopically implanted PC3LN3 prostate carcinoma. NVP-AUY922 inhibited proliferation, chemomigration, and tubular differentiation of human endothelial cells and antiangiogenic activity was reflected in reduced microvessel density in tumor xenografts. Collectively, the data show that NVP-AUY922 is a potent, novel inhibitor of HSP90, acting via several processes (cytostasis, apoptosis, invasion, and angiogenesis) to inhibit tumor growth and metastasis. NVP-AUY922 has entered phase I clinical trials.

Abstract
Syk, a non-receptor tyrosine kinase, is an important component of immunoreceptor signaling in hematopoietic cells. It has been implicated in key regulatory pathways including phosphoinositide 3-kinase and phospholipase Cgamma (PLCgamma) activation in B cells and integrin signaling in platelets and bronchial epithelial cells. Recently, potential roles in cancer have been reported. In breast cancers, reduced Syk expression was associated with invasion, and its overexpression in cell lines was shown to inhibit cell motility. In contrast, Syk has been shown to mediate chemomigration in nasopharyngeal carcinoma cells. Its role in squamous cell carcinomas of the head and neck (SCCHN) has not yet been investigated. Syk mRNA and protein expression was detected in 6 of 10 SCCHN cell lines. When Syk was transfected into Syk-negative cells (SIHN-011A), chemomigration was enhanced in vitro and this was associated with activation of PLCgamma1. Conversely, abrogation of Syk activity by pharmacologic inhibition or small interfering RNA in HN6 cells with high levels of endogenous expression inhibited migration, haptotaxis, and engagement with matrix proteins; this was accompanied by decreased levels of phosphorylated AKT. Similar effects were seen in Syk-positive CAL 27 cells but not in Syk-negative SIHN-011A cells. Immunoprecipitation suggested co-association of Syk with epidermal growth factor receptor and GRB-2. Syk expression in SCCHN patient tissues was examined by semiquantitative real-time PCR (n = 45) and immunohistochemistry (n = 38) in two independent cohorts. Higher levels of Syk expression were observed in tumors and lymph node metastases relative to normal tissues. High Syk expression significantly correlated with worse survival and may be of prognostic value in SCCHN due to its potential role in cell migration and invasion.

Abstract
Extensive evidence implicates activation of the lipid phosphatidylinositide 3-kinase (PI3K) pathway in the genesis and progression of various human cancers. PI3K inhibitors thus have considerable potential as molecular cancer therapeutics. Here, we detail the pharmacologic properties of a prototype of a new series of inhibitors of class I PI3K. PI103 is a potent inhibitor with low IC50 values against recombinant PI3K isoforms p110alpha (2 nmol/L), p110beta (3 nmol/L), p110delta (3 nmol/L), and p110gamma (15 nmol/L). PI103 also inhibited TORC1 by 83.9% at 0.5 micromol/L and exhibited an IC50 of 14 nmol/L against DNA-PK. A high degree of selectivity for the PI3K family was shown by the lack of activity of PI103 in a panel of 70 protein kinases. PI103 potently inhibited proliferation and invasion of a wide variety of human cancer cells in vitro and showed biomarker modulation consistent with inhibition of PI3K signaling. PI103 was extensively metabolized, but distributed rapidly to tissues and tumors. This resulted in tumor growth delay in eight different human cancer xenograft models with various PI3K pathway abnormalities. Decreased phosphorylation of AKT was observed in U87MG gliomas, consistent with drug levels achieved. We also showed inhibition of invasion in orthotopic breast and ovarian cancer xenograft models and obtained evidence that PI103 has antiangiogenic potential. Despite its rapid in vivo metabolism, PI103 is a valuable tool compound for exploring the biological function of class I PI3K and importantly represents a lead for further optimization of this novel class of targeted molecular cancer therapeutic.
