Abstract
Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating neurologic disease with high mortality and disability. There have been global improvements in survival, which has contributed to the prevalence of patients living with long-term sequelae related to this disease. The focus of active research has traditionally centered on acute treatment to reduce mortality, but now there is a great need to study the course of short- and long-term recovery in these patients. In this narrative review, we aim to describe the core pillars in the preservation of cerebral function, prevention of complications, the recent literature studying neuroplasticity, and future directions for research to enhance recovery outcomes following aSAH.

Abstract
BACKGROUND In patients with disorders of consciousness (DoC), laboratory and molecular biomarkers may help define endotypes, identify therapeutic targets, prognosticate outcomes, and guide patient selection in clinical trials. We performed a systematic review to identify common data elements (CDEs) and key design elements (KDEs) for future coma and DoC research. METHODS The Curing Coma Campaign Biospecimens and Biomarkers work group, composed of seven invited members, reviewed existing biomarker and biospecimens CDEs and conducted a systematic literature review for laboratory and molecular biomarkers using predetermined search words and standardized methodology. Identified CDEs and KDEs were adjudicated into core, basic, supplemental, or experimental CDEs per National Institutes of Health classification based on level of evidence, reproducibility, and generalizability across different diseases through a consensus process. RESULTS Among existing National Institutes of Health CDEs, those developed for ischemic stroke, traumatic brain injury, and subarachnoid hemorrhage were most relevant to DoC and included. KDEs were common to all disease states and included biospecimen collection time points, baseline indicator, biological source, anatomical location of collection, collection method, and processing and storage methodology. Additionally, two disease core, nine basic, 24 supplemental, and 59 exploratory biomarker CDEs were identified. Results were summarized and generated into a Laboratory Data and Biospecimens Case Report Form (CRF) and underwent public review. A final CRF version 1.0 is reported here. CONCLUSIONS Exponential growth in biomarkers development has generated a growing number of potential experimental biomarkers associated with DoC, but few meet the quality, reproducibility, and generalizability criteria to be classified as core and basic biomarker and biospecimen CDEs. Identification and adaptation of KDEs, however, contribute to standardizing methodology to promote harmonization of future biomarker and biospecimens studies in DoC. Development of this CRF serves as a basic building block for future DoC studies.

Abstract
Background: The mental health impacts of climate change-related disasters are significant. However, access to mental health services is often limited by the availability of trained clinicians. Although building local community capability for the mental health response is often prioritised in policy settings, the lack of evidence-based programs is problematic. The aim of this study was to test the efficacy of the Skills for Life Adjustment and Resilience programme (SOLAR) delivered by trained local community members following compound disasters (drought, wildfires, pandemic-related lockdowns) in Australia.Method: Thirty-six community members were trained to deliver the SOLAR programme, a skills-based, trauma informed, psychosocial programme. Sixty-six people with anxiety, depression and/or posttraumatic stress symptoms, and impairment were randomised into the SOLAR programme or a Self-Help condition. They were assessed pre, post and two months following the interventions. The SOLAR programme was delivered across five 1-hourly sessions (either face to face or virtually). Those in the Self-Help condition received weekly emails with self-help information including links to online educational videos.Results: Multigroup analyses indicated that participants in the SOLAR condition experienced significantly lower levels of anxiety and depression, and PTSD symptom severity between pre - and post-intervention (T1 to T2), relative to the Self-Help condition, while controlling for scores at intake. These differences were not statistically different at follow-up. The SOLAR programme was associated with large effect size improvements in posttraumatic stress symptoms over time.Conclusion: The SOLAR programme was effective in improving anxiety, depression and posttraumatic stress symptoms over time. However, by follow-up the size of the effect was similar to an active self-help condition. Given the ongoing stressors in the community associated with compounding disasters it may be that booster sessions would have been useful to sustain programme impact.Trial registration: Australian New Zealand Clinical Trials Registry identifier: ACTRN12621000283875..

Abstract
Background: Survivors of critical illness experience high rates of serious health-related suffering. The delivery of palliative care may assist in decreasing this burden for survivors and their families. Objectives: To understand beliefs, attitudes, and experiences of post-intensive care unit (ICU) program clinicians regarding palliative care and explore barriers and facilitators to incorporating palliative care into critical illness survivorship care. Design: Qualitative inquiry using semistructured interviews and framework analysis. Results were mapped using the Consolidated Framework for Implementation Research. Setting/Subjects: We interviewed 29 international members (United States, United Kingdom, Canada) of the Critical and Acute Illness Recovery Organization post-ICU clinic collaborative. Results: All interprofessional clinicians described components of palliative care as essential to post-ICU clinic practice, including symptom management, patient/family support, facilitation of goal-concordant care, expectation management and anticipatory guidance, spiritual support, and discussion of future health care wishes and advance care planning. Facilitators promoting palliative care strategies were clinician level, including first-hand experience, perceived value, and a positive attitude regarding palliative care. Clinician-level barriers were reciprocals and included insufficient palliative care knowledge, lack of self-efficacy, and a perceived need to protect ICU survivors from interventions the clinician felt may adversely affect recovery or change the care trajectory. System-level barriers included time constraints, cost, and lack of specialty palliative care services. Conclusion: Palliative care may be an essential element of post-ICU clinic care. Implementation efforts focused on tailoring strategies to improve post-ICU program clinicians' palliative care knowledge and self-efficacy could be a key to enhanced care delivery for survivors of critical illness.

Abstract
PURPOSE Adolescents with cancer routinely report feelings of isolation and exclusion, including from medical decision-making. To address this problem and support adolescents, we designed and implemented the novel, virtual, weekly Teens4Teens peer support group and patient education program. We examined the views of participating adolescents, program guest speakers, and program moderators as they pertained to the need for the program, its feasibility, acceptability, and perceived impact. METHODS We recruited all available adolescents, moderators, and guest speakers who participated in Teens4Teens to take part in audio-recorded, semi-structured interviews. Interviews were transcribed, coded, and analyzed using thematic analysis. RESULTS We conducted 21 interviews across participant groups. We identified four broad themes: pathways into the Teen4Teens program, Teens4Teens implementation capacity, perspectives of the positive impact of Teens4Teens, and suggestions to improve Teens4Teens. These themes described a perceived need for adolescent-centered psychosocial programming in pediatric cancer care, provided lessons on how best to build and apply such a program, and highlighted the value of the program for both adolescents' and clinicians' acceptability, feasibility, and perceived utility. CONCLUSION Adolescents, guest speakers, and moderators valued Teens4Teens and made suggestions to improve capacity to routinely implement the program. Adolescent-tailored psychosocial programming, such as Teens4Teens, is positioned to be integrated into clinical care with relative ease and may serve to improve the cancer care experience of adolescents and their families. This study has potential to provide researchers and clinicians with valuable information about the content, design, and delivery of virtual peer support programming for adolescents with cancer.

Abstract
Candidate gene studies have identified genetic variants associated with clinical outcomes following aneurysmal subarachnoid haemorrhage (aSAH), but no genome-wide association studies have been performed to date. Here we report the results of the discovery phase of a two-stage genome-wide meta-analysis of outcome after aSAH. We identified 157 independent loci harbouring 756 genetic variants associated with outcome after aSAH (p < 1 × 10-4), which require validation. A single variant (rs12949158), in SPNS2, achieved genome-wide significance (p = 4.29 × 10-8) implicating sphingosine-1-phosphate signalling in outcome after aSAH. A large multicentre international effort to recruit samples for validation is required and ongoing. Validation of these findings will provide significant insight into the pathophysiology of outcomes after aSAH with potential implications for treatment.

Abstract
PURPOSE/OBJECTIVE(S) In HERMES (NCT04595019) men with localized prostate cancer are treated on the Unity MR-Linac platform (MRL, Elekta AB, Stockholm) and randomized between stereotactic body radiotherapy (SBRT) with 36.25 Gy in 5 fractions and 24 Gy in 2 fractions. Patients randomized to two fractions receive 24 Gy to the high risk PTV, 20 Gy to the low risk PTV and a boost of 27 Gy to the dominant intraprostatic lesion. This study explores dose received by the target and organs at risk (OARs) when considering intrafraction motion in two fraction SBRT. MATERIALS/METHODS Targets and OARs were delineated and a reference plan generated on Monaco v5.40.01 (Elekta). An Adapt-to-Shape (ATS) workflow was used. Contours were propagated to the session MRI (MRIsession) and edited accordingly. Prior to delivery, a verification MRI (MRIverif) was acquired with baseline shifts corrected for using the Adapt-to-Position (ATP-of-ATS) workflow. A post treatment MRI (MRIpost) was acquired after delivery. Men in the 2-fraction arm received each fraction in 2 sub-fractions sequentially on the same day, to mitigate intrafraction motion. The plans of 5 men receiving 2 fraction SBRT were analyzed. The targets, urethra, bladder and rectum were recontoured on the MRIverif and MRIpost. Delivered plans were recalculated on the corresponding MRIverif and MRIpost. The percentage of optimal and mandatory target dose constraints met were calculated. Accumulated OAR doses were calculated by averaging their respective dose statistics across all sub-fractions, conservatively assuming that the same area of the OAR receives the maximum dose each fraction. Analysis was carried out separately for MRIverif and MRIpost as the true 'delivered dose' most likely lies between these two estimates. RESULTS There was good coverage across all fractions. The mandatory constraints of CTVpsv V24.0 Gy > 95% and CTVsv V20.0 Gy > 95% were met in 100% of fractions and V2700cGy > 95% in 90% on the MRIpost. Table 3 shows OAR dose. CONCLUSION This work demonstrates that target coverage is good, even for the GTV where no margin is applied. With our conservative dose calculation approach, we found dose constraints are exceeded for some patients. However, treatment has been well tolerated, suggesting that that our current dose constraints may be cautious. Once Elekta's True Tracking and automated gating software is implemented at our center we will be able to further improve OAR clinical goal compliance.

Abstract
Background Prolonged Exposure (PE), a trauma-focused therapy, is one of the most efficacious treatments available for PTSD. However, many people with PTSD do not lose their diagnosis following delivery of PE. The Unified Protocol (UP) for Transdiagnostic Treatment of Emotional Disorders is a non-trauma focused treatment that may offer an alternative treatment for PTSD. Methods This paper describes the study protocol for IMPACT, an assessor-blinded randomized controlled trial that examines the non-inferiority of UP relative to PE for participants who meet DSM-5 criteria for current PTSD. One hundred and twenty adult participants with PTSD will be randomized to receive either 10 × 90-min sessions of UP or PE with a trained provider. The primary outcome is severity of PTSD symptoms assessed by the Clinician Administered PTSD Scale for DSM-5 (CAPS-5) at post-treatment. Discussion While evidence-based treatments are available for PTSD, high levels of treatment dropout and non-response require new approaches to be tested. The UP is based on emotion regulation theory and is effective in treating anxiety and depressive disorders, however, there has been limited application to PTSD. This is the first rigorous study comparing UP to PE in a non-inferiority randomized controlled trial and may help improve clinical outcomes for those with PTSD. Trial registration This trial was prospectively registered with the Australian New Zealand Clinical Trials Registry, Trial ID (ACTRN12619000543189).

Abstract
This proceedings article presents actionable research targets on the basis of the presentations and discussions at the 2nd Curing Coma National Institutes of Health (NIH) symposium held from May 3 to May 5, 2021. Here, we summarize the background, research priorities, panel discussions, and deliverables discussed during the symposium across six major domains related to disorders of consciousness. The six domains include (1) Biology of Coma, (2) Coma Database, (3) Neuroprognostication, (4) Care of Comatose Patients, (5) Early Clinical Trials, and (6) Long-term Recovery. Following the 1st Curing Coma NIH virtual symposium held on September 9 to September 10, 2020, six workgroups, each consisting of field experts in respective domains, were formed and tasked with identifying gaps and developing key priorities and deliverables to advance the mission of the Curing Coma Campaign. The highly interactive and inspiring presentations and panel discussions during the 3-day virtual NIH symposium identified several action items for the Curing Coma Campaign mission, which we summarize in this article.

Abstract
BackgroundRecruitment of candidates is a cost- and effort-intensive aspect of rheumatology fellowship programs. For program leaders to efficiently use the available resources and improve recruitment outcomes, it is imperative to understand the attributes that influence the candidates’ choice of a program. Previous studies have examined the type and relative importance of the factors that candidates use in selecting other fellowship programs (1, 2). However, no such studies have been conducted in the field of rheumatology.ObjectivesTo examine the factors that influence the selection of fellowship programs by rheumatology applicants.MethodsAn anonymous, web-based survey comprised of 13 questions was shared with rheumatology fellowship applicants on messaging applications and online forums. The survey was open from 10/29/2021-11/06/2021. Participation was voluntary and informed consent was implied through the participants’ response. Three reminders to complete the survey were sent. Four domains of the applicant’s perception in relation to their preference of ranking rheumatology programs were assessed: (1) program prestige, (2) program structure, (3) interview day experience, and (4) career path of the alumni. The survey questions were devised in one of the following formats: (1) 5-point Likert scale, (2) rank order questions, (3) yes/no questions, (4) multiple choice questions, and (5) open-ended questions.ResultsThirty-two rheumatology applicants responded to the survey. The prestige of the program was reported to be extremely important by 16%, very important by 19%, somewhat important by 44%, and little or not important by 21% responders. The opportunity to see a diverse patient population was reported to be important by 97% respondents. The call schedule and higher number of fellows were considered important by 88% of the respondents. 66% preferred programs with higher number of faculty members. 69% favored programs with an ultrasound curriculum. The availability of clinician-educator track (18%), MCR/MPH (14%), and T32 grand (4%) were considered less important. 69% reported that the opportunity to train at a Veterans Administration hospital did not influence their choice. Regarding interview day experience, interaction with the faculty (63%) and the fellows (17%) were considered important factors influencing program ranking. Respondents preferred programs with alumni in academic clinician track (45%) and private practice (43%) compared to programs with alumni in academic research (13%) or industry pathway (4%). The geographical location of the program including the cost of living and location of significant others also influenced the applicants’ choice.ConclusionTo the best of our knowledge, this is the first survey to assess the attributes that influence a candidate’s choice of a rheumatology fellowship program. Our survey demonstrated that a positive interview day experience and program attributes including the opportunity to interact with a diverse patient population, relaxed call schedule, higher number of fellows and faculty, the presence of an ultrasound curriculum, and the location were the dominant factors influencing applicants’ choice of a program. The main limitation of our study is the lack of generalizability due to selection bias. Understanding the factors involved in decision making of the rheumatology fellowship applicants can provide valuable information for both the applicants and the programs and therefore lead to a better match.References[1]Kelm DJ, Skalski JH, Nelson DR, Kashani KB, Lee AS, Wesselius LJ, et al.

Abstract
ABSTRACT BACKGROUND: The American Association of Neuroscience Nurses established a 6-member Research Agenda Task Force in 2019 to identify neuroscience nursing research priorities to lead the field for the next 3 to 5 years. An early step in the process was a literature search to gain an understanding of the current landscape of neuroscience nursing research. METHODS: A search strategy was developed to locate relevant neuroscience nursing research. An experienced medical librarian performed a comprehensive systematic search of multiple databases. Task force members then further refined the search. A separate search was conducted to locate published research by 21 known neuroscience nurse researchers. RESULTS: An initial search located 466 qualitative articles and 1243 quantitative articles, with a further 655 articles published by known neuroscience nurse researchers. All 2364 citations were reviewed by task force members of the working in pairs to screen titles and abstracts for relevance. Nine categories of neuroscience nursing research were identified: quality of life, nursing practice, biomarkers, health promotion, professional development, technology, nursing care outcomes, assessment, and caregivers. Most of the research used descriptive methods, including both quantitative and qualitative methods of inquiry, providing a foundation for more rigorous investigation and interventional research. Research following stroke and the critical care setting were most prevalent. DISCUSSION: New and emerging trends in neuroscience nursing research include the use of technology, biomarkers, lay caregivers, strategies, and tools, including measure development for neurological assessment, and the evaluation of nursing practice including the practice environment and advanced practice nurse providers. Gaps were also evident. CONCLUSION: There is a significant need to expand neuroscience nursing in areas of emerging trends and to use rigorous methods to evaluate nursing practice effects on patient outcomes. The results of this search were used to revise the neuroscience nursing priorities last determined in 2011.

ABSTRACT BACKGROUND: Establishing research priorities is essential not only to support evidence-based nursing practice but also to direct research agendas for nursing organizations such as the American Association of Neuroscience Nursing. METHODS: A 6-member Research Agenda Task Force selected potential research priorities based on a literature search of neuroscience nursing research. Using a 2-round, modified Delphi methodology, electronic surveys were distributed to 53 neuroscience nursing experts to gain consensus on the research priorities for neuroscience nursing. Survey data included demographics, agreement with selected gaps in neuroscience nursing research, and impact of selected neuroscience nursing research topics on the field. RESULTS: Twenty-six of 53 experts (49% response rate) participated in round 1, and 30 of 53 experts (57% response rate) participated in round 2. In round 1, the Research Agenda Task Force members revised the list of gaps in neuroscience nursing research to include only the top 39 ranked topics with greater than or equal to 73% agreement, created a new category "Professional Practice Issues," and added 1 additional topic. In round 2, 14 topics were ranked greater than or equal to 70% impactful and identified as the top neuroscience nursing research priorities. CONCLUSION: The results of this study served as an effort for creating research priorities and enhancing research collaboration that focuses on neuroscience nursing. Focusing on gaps in the literature and setting research priorities can ultimately improve patient outcomes. Neuroscience nursing research priorities can be used to inform, guide, and aid nurse scientists, educators, and providers, and to inform agencies that provide research and program funding.

Abstract
Aneurysmal subarachnoid haemorrhage (aSAH) results in persistent clinical deficits which prevent survivors from returning to normal daily functioning. Only a small fraction of the variation in clinical outcome following aSAH is explained by known clinical, demographic and imaging variables; meaning additional unknown factors must play a key role in clinical outcome. There is a growing body of evidence that genetic variation is important in determining outcome following aSAH. Understanding genetic determinants of outcome will help to improve prognostic modelling, stratify patients in clinical trials and target novel strategies to treat this devastating disease. This protocol details a two-stage genome-wide association study to identify susceptibility loci for clinical outcome after aSAH using individual patient-level data from multiple international cohorts. Clinical outcome will be assessed using the modified Rankin Scale or Glasgow Outcome Scale at 1–24 months. The stage 1 discovery will involve meta-analysis of individual-level genotypes from different cohorts, controlling for key covariates. Based on statistical significance, supplemented by biological relevance, top single nucleotide polymorphisms will be selected for replication at stage 2. The study has national and local ethical approval. The results of this study will be rapidly communicated to clinicians, researchers and patients through open-access publication(s), presentation(s) at international conferences and via our patient and public network.

Abstract
Abstract
Introduction
Self-harm rates in the UK are increasing. Healthcare professionals’ beliefs regarding repeat attendance; attention-seeking; and poor treatment compliance may contribute to patients’ stigma. Self-inflicted burns (SIB) constitute a minority of burns cases, but require disproportionate healthcare input, yet little is known about these patients. Our aim was to evaluate presentations, compliance and outcomes in this patient group.
Method
A retrospective audit of outpatients with SIBs attending a UK Burns Unit over four years (Jan 2016-Dec 2019).
Results
Over the study period, 58 patients presented with 94 burn wounds. Incidence doubled over one year (2018-2019). Most patients were female (85%) with a median age of 29 years (range 19-62). The most commonly associated psychiatric diagnosis was personality disorder. On presentation 22% (n = 21) were admitted under the Mental Health Act. For 83% (n = 48) it was their first presentation with a SIB, although 74% had previously presented with non-burn self-harm. Median burn size was 0.5% TBSA, the most common mechanism was contact (48%) and 77% were deep (n = 77). 92% were compliant with treatment and did not tamper with their wounds or dressings.
Conclusions
The majority, 70% (n = 41), of patients only presented once to the Burns Department during the study period. This challenges the commonly held stereotype that those who self-harm will also seek attention through repeat presentation. Ongoing education among health professionals may dispel some myths regarding these individuals. Further, larger investigations, may permit rigorous comparison of treatment outcomes with non-SIB patients.

Abstract
BACKGROUND Understanding and improving obstetrical quality and safety is an important goal of professional societies, and many interventions such as checklists, safety bundles, educational interventions, or other culture changes have been implemented to improve the quality of care provided to obstetrical patients. Although many factors contribute to delivery decisions, a reduced workload has addressed how provider issues such as fatigue or behaviors surrounding impending shift changes may influence the delivery mode and outcomes. OBJECTIVE The objective was to assess whether intrapartum obstetrical interventions and adverse outcomes differ based on the temporal proximity of the delivery to the attending's shift change. STUDY DESIGN This was a secondary analysis from a multicenter obstetrical cohort in which all patients with cephalic, singleton gestations who attempted vaginal birth were eligible for inclusion. The primary exposure used to quantify the relationship between the proximity of the provider to their shift change and a delivery intervention was the ratio of time from the most recent attending shift change to vaginal delivery or decision for cesarean delivery to the total length of the shift. Ratios were used to represent the proportion of time completed in the shift by normalizing for varying shift lengths. A sensitivity analysis restricted to patients who were delivered by physicians working 12-hour shifts was performed. Outcomes chosen included cesarean delivery, episiotomy, third- or fourth-degree perineal laceration, 5-minute Apgar score of <4, and neonatal intensive care unit admission. Chi-squared tests were used to evaluate outcomes based on the proportion of the attending's shift completed. Adjusted and unadjusted logistic models fitting a cubic spline (when indicated) were used to determine whether the frequency of outcomes throughout the shift occurred in a statistically significant, nonlinear pattern RESULTS: Of the 82,851 patients eligible for inclusion, 47,262 (57%) had ratio data available and constituted the analyzable sample. Deliveries were evenly distributed throughout shifts, with 50.6% taking place in the first half of shifts. There were no statistically significant differences in the frequency of cesarean delivery, episiotomy, third- or fourth-degree perineal lacerations, or 5-minute Apgar scores of <4 based on the proportion of the shift completed. The findings were unchanged when evaluated with a cubic spline in unadjusted and adjusted logistic models. Sensitivity analyses performed on the 22.2% of patients who were delivered by a physician completing a 12-hour shift showed similar findings. There was a small increase in the frequency of neonatal intensive care unit admissions with a greater proportion of the shift completed (adjusted P=.009), but the findings did not persist in the sensitivity analysis. CONCLUSION Clinically significant differences in obstetrical interventions and outcomes do not seem to exist based on the temporal proximity to the attending physician's shift change. Future work should attempt to directly study unit culture and provider fatigue to further investigate opportunities to improve obstetrical quality of care, and additional studies are needed to corroborate these findings in community settings.

Abstract
Coma and disorders of consciousness (DoC) are highly prevalent and constitute a burden for patients, families, and society worldwide. As part of the Curing Coma Campaign, the Neurocritical Care Society partnered with the National Institutes of Health to organize a symposium bringing together experts from all over the world to develop research targets for DoC. The conference was structured along six domains: (1) defining endotype/phenotypes, (2) biomarkers, (3) proof-of-concept clinical trials, (4) neuroprognostication, (5) long-term recovery, and (6) large datasets. This proceedings paper presents actionable research targets based on the presentations and discussions that occurred at the conference. We summarize the background, main research gaps, overall goals, the panel discussion of the approach, limitations and challenges, and deliverables that were identified.

Abstract
Background:People with rheumatoid arthritis (RA) have a higher risk of serious infections. The most common nosocomial infection in the United States (US) is Clostridioides difficile infection (CDI) and yet, little is known regarding the impact of comorbid RA on outcomes in persons hospitalized with CDI.Objectives:To evaluate the trends over time and predictors of inpatient mortality in hospitalized patients with CDI comparing those with and without RA.Methods:We used the National Inpatient Sample (NIS) database, the largest available all-payer database of inpatient hospitalizations in the US. Patients aged ≥18 years admitted with CDI from 2006-2018 were included. Patients with RA were identified using the International Classification of Diseases (ICD) 9 and 10 codes. Categorical variables between CDI patients with and without RA were compared using Chi-squared test. Temporal trends of hospitalization charges, length of stay (LOS) and inpatient mortality were assessed using the Cochrane Armitage test. Predictors of inpatient mortality were assessed using multivariable logistic regression adjusting for: age ≥65, sex, race, presence of RA, and Elixhauser comorbidity index.Results:There were 4,396,945 hospitalizations with a discharge diagnosis of CDI in the study period, of which 111,336 (2.5%) had a coexisting diagnosis of RA. Over the study period, the proportion of CDI patients with a diagnosis of RA increased from 1.7% in 2006 to 3.3% in 2018 with a statistically significant trend of rise (p trend<0.001). There were significantly more females in the RA group (78.2%) than without RA (57.5%), p <0.001. RA group was significantly younger (68.0 vs 70.7, P<0.001). Races were similar between the groups.The inflation-adjusted average charge for hospitalization for CDI without RA was significantly higher than for CDI with RA ($95,863 vs $73,025, p<0.001). There was an increasing trend in inflation-adjusted average charge for hospitalization for both CDI without RA ($76,966 in 2006 to $104,552 in 2018, p<0.001) and CDI with RA ($55,689 in 2006 to $77,295 in 2018, p<0.001). Patients with or without RA had the same median length of stay (LOS) of 7 days. But when trended over time, for patients without RA, the median LOS decreased from 8 days in 2006-08 to 6 days in 2016-18 whereas for patients with RA, the median LOS fluctuated between 6 and 7 days over the course of study period.CDI patients without RA had a significantly higher mortality over the study period than those with RA (7.8% vs 6.1%, p<0.001). Among non-RA CDI patients, mortality decreased from 9.3% in 2006 to 6.3% in 2018 (p trend <0.001). Hospitalizations of people with CDI and comorbid RA showed an overall decreasing trend (p trend <0.001).The multivariable analyses found age≥65 was associated with increased inpatient mortality (adjusted odds ratio [aOR], 1.77, 95% confidence interval [CI], 1.73-1.80), whereas a diagnosis of RA was associated with a decreased mortality (aOR 0.86, 95% CI, 0.81-0.91) (Table 1).Table 1.Predictors of inpatient mortalityaOR95% C.I. for aORP-valueLowerUpperAge ≥ 651.7651.7301.801<0.001Hospitalization years -Years 2006-2011Ref -Years 2011-20140.7070.6930.721<0.001 -Years 2015-20180.5820.5690.594<0.001Elixhauser Comorbidity Index1.0561.0551.056<0.001Rheumatoid Arthritis0.8590.8100.911<0.001Female0.8700.8550.885<0.001Race -WhiteRef -African American1.0711.0441.099<0.001 -Hispanic1.1441.1081.180<0.001 -Asian/Pacific Islander1.2671.2001.337<0.001 -Native American1.0220.9101.1470.716 -Other races1.2631.2011.329<0.001aOR = Adjusted Odds Ratio; C.I.= confidence intervalConclusion:In this nationwide study, among hospitalized patients with CDI, those with comorbid RA had significantly decreased odds of inpatient mortality than those without RA.

Abstract
Objective Robson's Ten Group Classification System (TGCS) creates clinically relevant sub‐groups for monitoring caesarean birth rates. This study assesses whether this classification can be derived from routine data in Europe and uses it to analyse national caesarean rates. Design Observational study using routine data. Setting Twenty‐seven EU member states plus Iceland, Norway, Switzerland and the UK. Population All births at ≥22 weeks of gestational age in 2015. Methods National statistical offices and medical birth registers derived numbers of caesarean births in TGCS groups. Main outcome measures Overall caesarean rate, prevalence and caesarean rates in each of the TGCS groups. Results Of 31 countries, 18 were able to provide data on the TGCS groups, with UK data available only from Northern Ireland. Caesarean birth rates ranged from 16.1 to 56.9%. Countries providing TGCS data had lower caesarean rates than countries without data (25.8% versus 32.9%, P = 0.04). Countries with higher caesarean rates tended to have higher rates in all TGCS groups. Substantial heterogeneity was observed, however, especially for groups 5 (previous caesarean section), 6, 7 (nulliparous/multiparous breech) and 10 (singleton cephalic preterm). The differences in percentages of abnormal lies, group 9, illustrate potential misclassification arising from unstandardised definitions. Conclusions Although further validation of data quality is needed, using TGCS in Europe provides valuable comparator and baseline data for benchmarking and surveillance. Higher caesarean rates in countries unable to construct the TGCS suggest that effective routine information systems may be an indicator of a country's investment in implementing evidence‐based caesarean policies. Tweetable abstract Many European countries can provide Robson's Ten‐Group Classification to improve caesarean rate comparisons. Many European countries can provide Robson's Ten‐Group Classification to improve caesarean rate comparisons.

Abstract
BACKGROUND Cutaneous squamous cell carcinoma (cSCC) is a common cancer that invades the dermis through the basement membrane. The role of the basement membrane in poorly differentiated cSCC is not well understood. OBJECTIVES To study the effect that loss of the laminin subunit alpha-3 (α3) chain from the tumour microenvironment has on tumour invasion and inflammatory cell recruitment. METHODS We examined the role of the basement membrane proteins laminin subunits α3, β3 and γ2 in SCC invasion and inflammatory cell recruitment using immunohistochemistry, short hairpin RNA knockdown, RNA-Seq, mouse xenograft models and patient tumour samples. RESULTS Analysis of SCC tumours and cell lines using antibodies specific to laminin chains α3, β3 and γ2 identified a link between poorly differentiated SCC and reduced expression of laminin α3 but not the other laminin subunits investigated. Knockdown of laminin α3 increased tumour invasion both in vitro and in vivo. Western blot and immunohistochemical staining identified increased phosphorylated myosin light chain with loss of laminin α3. Inhibition of ROCK (rho-associated protein kinase) but not Rac1 significantly reduced the invasive potential of laminin α3 knockdown cells. Knockdown of laminin subunits α3 and γ2 increased monocyte recruitment to the tumour microenvironment. However, only the loss of laminin α3 correlated with increased tumour-associated macrophages both in xenografted tumours and in patient tumour samples. CONCLUSIONS These data provide evidence that loss of the laminin α3 chain in cSCC has an effect on both the epithelial and immune components of cSCC, resulting in an aggressive tumour microenvironment.

Abstract
BACKGROUND The incidence of breech presentation in single pregnancies at term is between three to 5 %. In order to support eligible women in their choice of mode of delivery, a dedicated breech clinic with a care pathway was developed in December 2015 in a tertiary referral centre in Brussels. The primary objective of this study was to evaluate the vaginal birth rate before and after the introduction of a dedicated breech clinic. The secondary objective was to compare the early neonatal outcomes before and after the breech clinic was introduced. METHODS This was a single centre retrospective and prospective study. The inclusion criteria were term (from 37 weeks), singleton fetus and breech presentation at delivery. The exclusion criteria were suspected intrauterine growth restriction, severe fetal malformations and intrauterine fetal demise. We used a composite outcome as an indicator of neonatal morbidity and mortality. RESULTS After the introduction of the breech clinic, we observed a significant increase in planned vaginal delivery from 7.4% (12/162) to 53.0% (61/115) (OR: 13.5; 95% CI: 6.7-27.0). The effective vaginal breech delivery rate (planned and unexpected) significantly increased from 4.3% (7/162) pre-implementation of breech clinic to 43.5% (50/115) post-implementation (OR: 17.0; 95% CI: 7.3-39.6). Neonatal outcomes were not statistically different between the before and after periods. CONCLUSION The introduction of a dedicated breech clinic has led to an increase in vaginal deliveries for breech babies without adversely affecting neonatal outcomes.

Abstract
Traumatic brain injury (TBI) is a leading cause of death and disability, with more than 5 million people in the United States living with long-term complications related to TBI. This study examined the relationship between TP53, the gene that codes for the protein p53, and outcome variability following severe TBI. The p53 protein impacts neuronal apoptosis following TBI, thus investigation into TP53 genetic variability as a prognosticator for TBI outcomes (mortality, Glasgow Outcome Scale [GOS], Neurobehavioral Rating Scale [NRS], and Disability Rating Scale [DRS]) is warranted. Participants (N = 429) with severe TBI (Glasgow Coma Scale score ≤8) were enrolled into a prospective study with outcomes assessed over 24 months following injury. The single-nucleotide polymorphism Arg72Pro (rs1042522), a functional missense polymorphism for which the CC homozygous genotype is most efficient at inducing apoptosis, was investigated. Individuals with the CC genotype (arginine homozygotes) were more likely to have poorer outcomes at 24 months following TBI compared to individuals with CG/GG genotypes (GOS: p = .048, DRS: p = .022). These findings add to preliminary evidence that p53 plays a role in recovery following TBI and, if further replicated, could support investigations into p53-based therapies for treating TBI.

Abstract
Abstract
Despite the benefits of outdoor free-play for children (physical activity, well-being, independent mobility), access to urban spaces for play is on the decline in many cities. As such, there are increasing calls from public health officials, city planners and childhood advocates in Canada to promote outdoor play in cities. Responding to these calls, our pilot intervention will examine whether creating urban play spaces through road closures around schools and in neighbourhoods can increase children’s outdoor play, physical activity and social interaction among residents.
The year-long intervention will involve road closures in four Montreal (Canada) neighbourhoods with different socio-economic profiles. After a diagnostic portrait of each site, participatory planning will engage children aged 8-12 and youth aged 13-18 to help redesign their neighbourhood streets for better access and playability. Outdoor play will be measured using a “playability index” to determine if increased outdoor play is due to intervention changes. Children’s physical activity, play and mobility patterns will be captured with GPS loggers and accelerometers, and play duration and location will be recorded through daily diaries. Questionnaires will be given to parents and children regarding changing behaviours and perceptions about outdoor play, risk/safety and independent mobility. While still in a pilot phase, this paper will present the intervention approach and outline how it promises to impact multiple components of urban life for children and adults (physical/mental health, safety, social interaction, environment/equity).
The intervention is innovative by engaging children and families in its design and development, and by involving schools, municipalities and residents in its implementation and assessment. This co-creation and development promises broad impacts on local social practices and policy development, results which may be transferable to other Canadian and international cities.
Key messages
Access to urban outdoor play is critical for children’s well-being. Road closures can increase urban outdoor play, thereby contributing to physical and mental health and promoting social interaction. Child and youth participation in the planning and development of urban play spaces can increase their relevance and broaden their social, environmental, health and policy impacts.

Abstract
INTRODUCTION Routine histopathologic gallbladder examination after cholecystectomy has been a point of discussion. The aim of this study was to evaluate the macroscopic examination by the surgeon in relation to the final histology. METHODS A prospective study was conducted to investigate the practice of macroscopic gallbladder examination by a surgeon compared to routine histopathology by a pathologist. All consecutive cholecystectomies were included between November 2009 and February 2011. RESULTS A total of 319 consecutive cholecystectomies were performed. Of all macroscopic examinations, the surgeon identified 62 gallbladders with macroscopic abnormalities, ranging from polyps to wall thickening or ulcers. In 55 (17.2%) cases, the surgeon judged that further examination of the specimen by the pathologist could possibly lead to additional and relevant findings. There was a strong agreement between the surgeon and the pathologist concerning the macroscopic examination (κappa = 0.822). The surgeon and the pathologist had disagreement on the macroscopic examination of 18 gallbladders, without clinical consequences for the patient. DISCUSSION The present prospective study shows that the surgeon should be able to select those gallbladders needing a microscopic gallbladder examination. Potentially, about 80% of this kind of routine histology can be reduced.

Abstract
OBJECTIVE To perform an individual patient-level data (IPLD) analysis and to determine the relationship between haptoglobin (HP) genotype and outcomes after aneurysmal subarachnoid hemorrhage (aSAH). METHODS The primary outcome was favorable outcome on the modified Rankin Scale or Glasgow Outcome Scale up to 12 months after ictus. The secondary outcomes were occurrence of delayed ischemic neurologic deficit, radiologic infarction, angiographic vasospasm, and transcranial Doppler evidence of vasospasm. World Federation of Neurological Surgeons (WFNS) scale, Fisher grade, age, and aneurysmal treatment modality were covariates for both primary and secondary outcomes. As preplanned, a 2-stage IPLD analysis was conducted, followed by these sensitivity analyses: (1) unadjusted; (2) exclusion of unpublished studies; (3) all permutations of HP genotypes; (4) sliding dichotomy; (5) ordinal regression; (6) 1-stage analysis; (7) exclusion of studies not in Hardy-Weinberg equilibrium (HWE); (8) inclusion of studies without the essential covariates; (9) inclusion of additional covariates; and (10) including only covariates significant in univariate analysis. RESULTS Eleven studies (5 published, 6 unpublished) totaling 939 patients were included. Overall, the study population was in HWE. Follow-up times were 1, 3, and 6 months for 355, 516, and 438 patients. HP genotype was not associated with any primary or secondary outcome. No trends were observed. When taken through the same analysis, higher age and WFNS scale were associated with an unfavorable outcome as expected. CONCLUSION This comprehensive IPLD analysis, carefully controlling for covariates, refutes previous studies showing that HP1-1 associates with better outcome after aSAH.

Abstract
Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) equation is currently recommended for the estimation of glomerular filtration rate (GFR). This retrospective study aimed to evaluate the correlation between creatinine and cysC-based estimated GFRs and measured GFR in healthy adults. Consecutive healthy adults who were accepted as voluntary kidney donors at our center between January 2008 and December 2012 were included in the study. The 336 individuals who comprised the study population had a mean age of 41.6 ± 11.8 years, male:female ratio 1:1.7, mean creatinine 0.9 ± 0.1 mg/dl, and mean cysC 0.8 ± 0.1 mg/dl. Mean measured GFR by Tc-99m diethylenetriaminepentaacetic acid using Gates method was 98.4 ± 21.2 ml/min/1.73 m2. The mean ± standard deviation of eGFRs by various formulae were as follows: Cockcroft–Gault (CG) = 88.1 ± 15.9 ml/min/1.73 m2, Modification of Diet in Renal Disease (MDRD) = 78 ± 14.7 ml/min/1.73 m2, CKD-EPI creatinine = 88.1 ± 15.5 ml/min/1.73 m2, CKD-EPI cysC = 97 ± 19.9 ml/min/1.73 m2, CKD-EPI creatinine-cysC (CKD-EPI cr-cysC) = 92.5 ± 14.1 ml/min/1.73 m2. The CKD-EPI cr-cysC equation had the highest accuracy, with 43% and 72% of values lying within ±10% and ±20% of the measured GFR, respectively. Bland–Altman analyses for levels of agreement showed least bias with CKD-EPI cysC overall and among females, while among males, CKD-EPI creatinine equation had the least bias. The CKD-EPI equation showed a higher performance than the MDRD and CG equation in GFR estimation of a healthy population. Among CKD-EPI equations, CKD-EPI cr-cysC had the highest accuracy and CKD-EPI cysC the least bias.

Abstract
BACKGROUND Studies of early-term birth after demonstrated fetal lung maturity show that respiratory and other outcomes are worse with early-term birth (370-386 weeks) even after demonstrated fetal lung maturity when compared with full-term birth (390-406 weeks). However, these studies included medically indicated births and are therefore potentially limited by confounding by the indication for delivery. Thus, the increase in adverse outcomes might be due to the indication for early-term birth rather than the early-term birth itself. OBJECTIVE We examined the prevalence and risks of adverse neonatal outcomes associated with early-term birth after confirmed fetal lung maturity as compared with full-term birth in the absence of indications for early delivery. STUDY DESIGN This is a secondary analysis of an observational study of births to 115,502 women in 25 hospitals in the United States from 2008 through 2011. Singleton nonanomalous births at 37-40 weeks with no identifiable indication for delivery were included; early-term births after positive fetal lung maturity testing were compared with full-term births. The primary outcome was a composite of death, ventilator for ≥2 days, continuous positive airway pressure, proven sepsis, pneumonia or meningitis, treated hypoglycemia, hyperbilirubinemia (phototherapy), and 5-minute Apgar <7. Logistic regression and propensity score matching (both 1:1 and 1:2) were used. RESULTS In all, 48,137 births met inclusion criteria; the prevalence of fetal lung maturity testing in the absence of medical or obstetric indications for early delivery was 0.52% (n = 249). There were 180 (0.37%) early-term births after confirmed pulmonary maturity and 47,957 full-term births. Women in the former group were more likely to be non-Hispanic white, smoke, have received antenatal steroids, have induction, and have a cesarean. Risks of the composite (16.1% vs 5.4%; adjusted odds ratio, 3.2; 95% confidence interval, 2.1-4.8 from logistic regression) were more frequent with elective early-term birth. Propensity scores matching confirmed the increased primary composite in elective early-term births: adjusted odds ratios, 4.3 (95% confidence interval, 1.8-10.5) for 1:1 and 3.5 (95% confidence interval, 1.8-6.5) for 1:2 matching. Among components of the primary outcome, CPAP use and hyperbilirubinemia requiring phototherapy were significantly increased. Transient tachypnea of the newborn, neonatal intensive care unit admission, and prolonged neonatal intensive care unit stay (>2 days) were also increased with early-term birth. CONCLUSION Even with confirmed pulmonary maturity, early-term birth in the absence of medical or obstetric indications is associated with worse neonatal respiratory and hepatic outcomes compared with full-term birth, suggesting relative immaturity of these organ systems in early-term births.

Abstract
Introduction Management of hip fractures has evolved over recent years to drive better outcomes including length of hospital stay. We aimed to identify and quantify the effect that patient factors influence acute hospital and total health service length of stay. Methods A retrospective observational study based on National Hip Fracture Database data was conducted from 1 January 2014 to 31 December 2015. A multiple regression analysis of 330 patients was carried out to determine independent factors that affect acute hospital and total hospital length of stay. Results American Society of Anesthesiologists (ASA) grade 3 or above, Abbreviated Mental Test Score (AMTS) less than 8 and poor mobility status were independent factors, significantly increasing length of hospital stay in our population. Acute hospital length of stay can be predicted as 8.9 days longer when AMTS less than 8, 4.2 days longer when ASA grade was 3 or above and 20.4 days longer when unable to mobilise unaided (compared with independently mobile individuals). Other factors including total hip replacement compared with hemiarthroplasty did not independently affect length of stay. Conclusions Our analysis in a representative and generalisable population illustrates the importance of identifying these three patient characteristics in hip fracture patients. When recognised and targeted with orthogeriatric support, the length of hospital stay for these patients can be reduced and overall hip fracture care improved. Screening on admission for ASA grade, AMTS and mobility status allows prediction of length of stay and tailoring of care to match needs.
