Performance of the Medical Priority Dispatch System® in Identifying Patients Requiring Chest Compressions at Overdose Prevention Services: A Retrospective Cohort Study. PREHOSP EMERG CARE 2024:1-8. [PMID: 38407219 DOI: 10.1080/10903127.2024.2319150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Accepted: 02/08/2024] [Indexed: 02/27/2024]
Abstract
BACKGROUND AND AIMS The Medical Priority Dispatch System (MPDS)® is used to triage 9-1-1 calls according to acuity, with certain coding receiving telecommunicator cardiopulmonary resuscitation (T-CPR) for suspected out-of-hospital cardiac arrest (OHCA). However, this may be challenging for those with drug poisoning emergencies, who may resemble OHCA. We sought to examine the performance of the system to correctly identify cases requiring T-CPR, specifically at overdose prevention services (OPS). METHODS This retrospective cohort study included patients attended by the provincial emergency medical system (EMS) (May 1, 2019-January 31, 2023). We calculated the diagnostic performance of MPDS® assessment of whether the case required T-CPR instructions against the gold standard of whether the patient was found pulseless on EMS clinician arrival. We compared performance among subgroups, specifically OPS vs other locations and drug poisoning-classified cases vs other case classifications. RESULTS Comparing OPS to other locations, the sensitivity of MPDS® was similar (66.7% vs 62.4%, p = 0.4), with lower specificity (87.3% vs 98.1%, p < 0.01) and positive predictive value (0.3% vs 35.7%, p < 0.01) and higher negative predictive value (99.9% vs 99.4%, p < 0.01). The negative likelihood ratio of MPDS® was 0.381 at OPS locations, compared with 0.383 at other locations, while the positive likelihood ratio was 5.24, compared with 32.36. In patients with drug poisoning emergencies, compared with other 9-1-1 events, MPDS® had higher sensitivity (83.6% vs 60.6%, p < 0.01) but lower specificity (77.6% vs 98.9%, p < 0.01) and positive predictive value (10.5% vs 48.5%, p < 0.01), and similar negative predictive value (99.33% vs 99.35%, p = 0.03). The negative likelihood ratio of MPDS® was 0.212 in drug poisoning emergencies compared with 0.398 for all other presentations, and the positive likelihood ratio was 3.73 compared with 57.88. DISCUSSION AND CONCLUSIONS The ability of MPDS® to correctly identify patients needing telecommunicator cardiopulmonary resuscitation instructions differed between OPS settings and other locations, frequently recommending T-CPR for patients not suffering OHCA at an OPS. Different strategies developed in collaboration with people who use substances are required to better tailor dispatch instructions prior to EMS arrival to avoid delays in life-saving interventions.

The effects of short-term, progressive exercise training on disease activity in smouldering multiple myeloma and monoclonal gammopathy of undetermined significance: a single-arm pilot study. BMC Cancer 2024; 24:174. [PMID: 38317104 PMCID: PMC10840198 DOI: 10.1186/s12885-024-11817-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Accepted: 01/01/2024] [Indexed: 02/07/2024] Open
Abstract
BACKGROUND High levels of physical activity are associated with reduced risk of the blood cancer multiple myeloma (MM). MM is preceded by the asymptomatic stages of monoclonal gammopathy of undetermined significance (MGUS) and smouldering multiple myeloma (SMM) which are clinically managed by watchful waiting. A case study (N = 1) of a former elite athlete aged 44 years previously indicated that a multi-modal exercise programme reversed SMM disease activity. To build from this prior case study, the present pilot study firstly examined if short-term exercise training was feasible and safe for a group of MGUS and SMM patients, and secondly investigated the effects on MGUS/SMM disease activity. METHODS In this single-arm pilot study, N = 20 participants diagnosed with MGUS or SMM were allocated to receive a 16-week progressive exercise programme. Primary outcome measures were feasibility and safety. Secondary outcomes were pre- to post-exercise training changes to blood biomarkers of MGUS and SMM disease activity- monoclonal (M)-protein and free light chains (FLC)- plus cardiorespiratory and functional fitness, body composition, quality of life, blood immunophenotype, and blood biomarkers of inflammation. RESULTS Fifteen (3 MGUS and 12 SMM) participants completed the exercise programme. Adherence was 91 ± 11%. Compliance was 75 ± 25% overall, with a notable decline in compliance at intensities > 70% V̇O2PEAK. There were no serious adverse events. There were no changes to M-protein (0.0 ± 1.0 g/L, P =.903), involved FLC (+ 1.8 ± 16.8 mg/L, P =.839), or FLC difference (+ 0.2 ± 15.6 mg/L, P =.946) from pre- to post-exercise training. There were pre- to post-exercise training improvements to diastolic blood pressure (- 3 ± 5 mmHg, P =.033), sit-to-stand test performance (+ 5 ± 5 repetitions, P =.002), and energy/fatigue scores (+ 10 ± 15%, P =.026). Other secondary outcomes were unchanged. CONCLUSIONS A 16-week progressive exercise programme was feasible and safe, but did not reverse MGUS/SMM disease activity, contrasting a prior case study showing that five years of exercise training reversed SMM in a 44-year-old former athlete. Longer exercise interventions should be explored in a group of MGUS/SMM patients, with measurements of disease biomarkers, along with rates of disease progression (i.e., MGUS/SMM to MM).

The paramedic-general practitioner relationship: a scoping review. Aust J Prim Health 2023; 29:547-557. [PMID: 37574261 DOI: 10.1071/py23060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Accepted: 07/20/2023] [Indexed: 08/15/2023]
Abstract
BACKGROUND Health services internationally are implementing programs that increase working ties between paramedics and general practitioners (GPs) to reduce unnecessary transport to emergency departments (EDs) and improve access to primary health care. As paramedic involvement in primary health care develops, there is increasing focus on the GP-paramedic collaborative relationship. Resulting issues regarding professional boundaries may occur, as paramedics practice in fields that were previously solely in the GP scope. An effective paramedic-GP working relationship will be an essential foundation to the success of future strategies. METHODS A search of three electronic databases was completed (Ovid MEDLINE, Embase Classic+ Embase and CINAHL Plus). Eligibility for inclusion required analysis of the relationship between paramedics and GPs. All processes were completed by two independent reviewers. RESULTS After removal of duplicates, 4995 titles were screened by title and/or abstract. After full-text review, 15 studies were included. Five themes were identified that contribute significantly to the strengths and weaknesses of the relationship - the importance of communication, understanding scope of practice, leadership roles, responsibility for patient care and interdisciplinary training. Issues identified included significant variation in the structure of different emergency medical services and varying standards of education requirements for paramedics worldwide. CONCLUSIONS There were no published Australian studies that had the primary aim of examining the paramedic-GP relationship. The depth of research on this topic is lacking, despite increased interest over the past decade. The relevance of the international literature to the Australian setting is questionable.

Shaping the future design of paramedicine: A knowledge to action framework to support paramedic system modernization. Australas Emerg Care 2023; 26:296-302. [PMID: 36931964 DOI: 10.1016/j.auec.2023.03.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 03/02/2023] [Accepted: 03/06/2023] [Indexed: 03/17/2023]
Abstract
BACKGROUND Over the past two decades, the demands placed on modern paramedic systems has changed. Paramedic services can no longer continue to operate on a traditional response model where more ambulances are deployed to meet the rising demand of patients calling for their health needs. Recent research has explored system design in paramedicine and its relationship with organizational performance. Two subsequent paramedic systems have been identified with one, the Professionally Autonomous paramedic system, being linked to higher performance. Yet, how to operationalize this model for system modernization continues to be a gap in practice. OBJECTIVE To provide health leaders and policy makers with a framework from which to drive paramedic system modernization. METHODS This study uses the Knowledge to Action framework to develop an implementation plan for systems that seek to modernize their service delivery model toward that of a Professionally Autonomous paramedic system. RESULTS A detailed plan of the steps required to undertake system transformation are outlined. Whilst this framework outlines the components required for system modernization, it does not propose an in-depth outline of each of the steps required to achieve each component. Rather, end users are encouraged to develop individual implementation plans tailored to the local context using the comprehensive tools outlined within. CONCLUSION This knowledge to action framework provides health leaders and policy makers with a uniform roadmap for paramedic system modernization intended to improve health (clinical) outcomes as well as health system outcomes through the Professional Autonomous paramedicine model.

Interprofessional peer assisted learning: Paramedic students learning falls assessments from Occupational Therapy students. J Interprof Care 2023; 37:1032-1035. [PMID: 37190769 DOI: 10.1080/13561820.2023.2208606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 04/24/2023] [Accepted: 04/25/2023] [Indexed: 05/17/2023]
Abstract
Peer-assisted learning (PAL) describes a program in which students learn from students from the same health discipline. This teaching method has gained significant momentum over the past decade as an effective learning strategy for undergraduate healthcare students. Paramedic programs are increasingly utilizing PAL, however there is a scarcity of literature about interprofessional PAL, particularly between Paramedics and allied health students. This project was an evaluation of a pilot educational intervention involving final year undergraduate paramedic students. Occupational Therapy (OT) peer instructors facilitated a session on falls' risk assessments during a scheduled undergraduate Paramedic practical class. The OT peer instructors discussed pertinent considerations for Paramedics attending to elderly patients who have fallen, and then provided direct feedback to the Paramedic students during a case simulation. At the conclusion of the session, Paramedic students completed a survey evaluating their reaction to and learning from the teaching session. Results indicated that interprofessional PAL can improve undergraduate paramedic students' knowledge and confidence in performing a new skill that is well understood by another allied health profession. This adds to the body of empirical research on interprofessional PAL and supports its inclusion as a teaching modality into undergraduate healthcare programs such as Paramedicine.

Strengths and challenges with spiritual care: Student feedback from the EPICC Spiritual Care Self-Assessment Tool. Nurs Open 2023; 10:6923-6934. [PMID: 37475149 PMCID: PMC10495739 DOI: 10.1002/nop2.1946] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 06/10/2023] [Accepted: 07/07/2023] [Indexed: 07/22/2023] Open
Abstract
AIM To explore qualitative data from students' self-reported competencies in spiritual care gathered during testing of a student self-assessment tool based on the EPICC Spiritual Care Education Standard. DESIGN Reflexive thematic analysis of qualitative data from a multinational study on validating a new self-assessment tool. METHODS The EPICC Spiritual Care Education Standard for competency in spiritual care was developed to enhance nurses' and midwives' ability to provide spiritual care by creating a baccalaureate education standard for spiritual care competencies. Spiritual care researchers then developed a self-assessment tool to raise student awareness of spirituality and track personal and professional growth in spiritual care competency. The EPICC Spiritual Care Competency Self-Assessment Tool, tested at eight universities in five countries, provided many opportunities for student comments, resulting in rich qualitative data presented here. RESULTS Themes related to strengths, weaknesses and areas for improvement. Identified strengths were similar across countries: caring attitudes, general knowledge of caring and compassion and good communication skills. Weaknesses/challenges touched on spirituality as overlooked in some cultures but part of life for others, complex questions were hard to understand, and self-assessment tools are common for some and rare for others. Areas for improvement included need for knowledge of religious and other deeply held beliefs and for greater spiritual assessment skills. Similarities across countries related to basic training in communication and compassionate care for nurses globally. Differences lay in the challenges and/or barriers for spiritual care and may relate to cultures within countries and/or university test sites. RELEVANCE TO CLINICAL PRACTICE The Tool raises awareness of spirituality among students and working nurses, providing an accessible way to self-check personal and professional growth in spiritual care competencies, which increases student and nurse capacity to become more knowledgeable and skilled in facilitating spiritual care, thus be role models for students at the intersection of spirituality and health.

DNA methylation is associated with codon degeneracy in a species of bumblebee. Heredity (Edinb) 2023; 130:188-195.

Abstract
Social insects display extreme phenotypic differences between sexes and castes even though the underlying genome can be almost identical. Epigenetic processes have been proposed as a possible mechanism for mediating these phenotypic differences. Using whole genome bisulfite sequencing of queens, males, and reproductive female workers we have characterised the sex- and caste-specific methylome of the bumblebee Bombus terrestris. We have identified a potential role for DNA methylation in histone modification processes which may influence sex and caste phenotypic differences. We also find differentially methylated genes generally show low levels of DNA methylation which may suggest a separate function for lowly methylated genes in mediating transcriptional plasticity, unlike highly methylated genes which are usually involved in housekeeping functions. We also examined the relationship between the underlying genome and the methylome using whole genome re-sequencing of the same queens and males. We find DNA methylation is enriched at zero-fold degenerate sites. We suggest DNA methylation may be acting as a targeted mutagen at these sites, providing substrate for selection via non-synonymous changes in the underlying genome. However, we did not see any relationship between DNA methylation and rates of positive selection in our samples. In order to fully assess a possible role for DNA methylation in adaptive processes a specifically designed study using natural population data is needed.

Developing and testing the EPICC Spiritual Care Competency Self-Assessment Tool for student nurses and midwives. J Clin Nurs 2023; 32:1148-1162. [PMID: 35285563 DOI: 10.1111/jocn.16261] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Revised: 01/31/2022] [Accepted: 02/03/2022] [Indexed: 11/29/2022]
Abstract
AIMS AND OBJECTIVES To develop and psychometrically test a self-assessment tool that measures undergraduate nursing and midwifery students' perceptions of spiritual care competence in health care practice. BACKGROUND Spiritual care is part of nurses/midwives' responsibility. There is a need to better benchmark students' competency development in spiritual care through their education. The EPICC Spiritual Care Education Standard served as groundwork for the development of the EPICC Spiritual Care Competency Self-Assessment Tool. DESIGN Cross sectional, mixed methods design. A STROBE checklist was used. METHODS The Tool (available in English, Dutch and Norwegian) was developed by an international group. It was tested between July-October 2020 with a convenience sample of 323 nursing/midwifery students at eight universities in five countries. The Tool was tested for validity using Kaiser-Meyer-Olkin (KMO) test, exploratory and confirmatory factor analysis, one-way ANOVA and independent samples t test. The reliability was tested by Cronbach's alpha coefficient. Qualitative data were analysed using thematic analysis. RESULTS The KMO test for sampling adequacy was 0.90. All, but two, items were related to the same factor. Cronbach's alpha coefficient for the Tool was 0.91. Students found the Tool easy to use, and they gained new insights by completing it. However, students felt that some questions were repetitive and took time to complete. CONCLUSIONS The Tool has construct and discriminant validity, and high internal consistency (is reliable). In addition, students found the Tool useful, especially in early stages of education. RELEVANCE TO CLINICAL PRACTICE The Tool affords student nurses and midwives the opportunity to self-evaluate their knowledge, skills and attitudes about spirituality and spiritual care. The Tool offers students, educators and preceptors in clinical practice a tangible way of discussing and evaluating spiritual care competency.

Abstract
Introduction In recent years, researchers have identified two new models of paramedicine within the Anglo-American paramedic system known as the Directive and Professionally Autonomous paramedic systems. The research team now seek to compare paramedic perception of system performance between the two systems using prehospital quality indicators. Methods Paramedics employed within Anglo-American paramedic systems undertook a survey evaluating their experience and perception of system performance against a set of modified prehospital quality indicators. Data were collected using a survey combining single-choice questions with matrix multiple-choice questions. Key results were cross-tabulated with demographic (informant) and system factors to compare performance between the two new paramedic systems. Results The survey indicated a substantial difference in perceived clinical and operational performance between the Professionally Autonomous and Directive paramedic systems, with the Professionally Autonomous paramedic system performing consistently better in all 11 prehospital quality indicator domains. Conclusion The results of this survey are a vital step in helping paramedics, health leaders, and academics understand the complex relationship between paramedic system design and system performance, and, for the first time, provides empirical evidence upon which to make a conscious decision to adopt one system or the other.

Clinical reasoning in undergraduate paramedicine: utilisation of a script concordance test. BMC MEDICAL EDUCATION 2023; 23:39. [PMID: 36658560 PMCID: PMC9849838 DOI: 10.1186/s12909-023-04020-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Accepted: 01/11/2023] [Indexed: 06/17/2023]
Abstract
INTRODUCTION Clinical reasoning is a complex cognitive and metacognitive process paramount to patient care in paramedic practice. While universally recognised as an essential component of practice, clinical reasoning has been historically difficult to assess in health care professions. Is the Script Concordance Test (SCT) an achievable and reliable option to test clinical reasoning in undergraduate paramedic students? METHODS This was a single institution observational cohort study designed to use the SCT to measure clinical reasoning in paramedic students. Clinical vignettes were constructed across a range of concepts with varying shades of clinical ambiguity. A reference panel mean scores of the test were compared to that of students. Test responses were graded with the aggregate scoring method with scores awarded for both partially and fully correct responses. RESULTS Eighty-three student paramedic participants (mean age: 21.8 (3.5) years, 54 (65%) female, 27 (33%) male and 2 (2%) non-binary) completed the SCT. The difference between the reference group mean score of 80 (5) and student mean of score of 65.6 (8.4) was statistically significant (p < 0.001). DISCUSSION Clinical reasoning skills are not easily acquired as they are a culmination of education, experience and the ability to apply this in the context to a specific patient. The SCT has shown to be reliable and effective in measuring clinical reasoning in undergraduate paramedics as it has in other health professions such as nursing and medicine. More investigation is required to establish effective pedogeological techniques to optimise clinical reasoning in student and novice paramedics who are devoid of experience.

Abstract
BACKGROUND The randomized, double-blind OlympiA trial compared 1 year of the oral poly(adenosine diphosphate-ribose) polymerase inhibitor, olaparib, to matching placebo as adjuvant therapy for patients with pathogenic or likely pathogenic variants in germline BRCA1 or BRCA2 (gBRCA1/2pv) and high-risk, human epidermal growth factor receptor 2-negative, early breast cancer (EBC). The first pre-specified interim analysis (IA) previously demonstrated statistically significant improvement in invasive disease-free survival (IDFS) and distant disease-free survival (DDFS). The olaparib group had fewer deaths than the placebo group, but the difference did not reach statistical significance for overall survival (OS). We now report the pre-specified second IA of OS with updates of IDFS, DDFS, and safety. PATIENTS AND METHODS One thousand eight hundred and thirty-six patients were randomly assigned to olaparib or placebo following (neo)adjuvant chemotherapy, surgery, and radiation therapy if indicated. Endocrine therapy was given concurrently with study medication for hormone receptor-positive cancers. Statistical significance for OS at this IA required P < 0.015. RESULTS With a median follow-up of 3.5 years, the second IA of OS demonstrated significant improvement in the olaparib group relative to the placebo group [hazard ratio 0.68; 98.5% confidence interval (CI) 0.47-0.97; P = 0.009]. Four-year OS was 89.8% in the olaparib group and 86.4% in the placebo group (Δ 3.4%, 95% CI -0.1% to 6.8%). Four-year IDFS for the olaparib group versus placebo group was 82.7% versus 75.4% (Δ 7.3%, 95% CI 3.0% to 11.5%) and 4-year DDFS was 86.5% versus 79.1% (Δ 7.4%, 95% CI 3.6% to 11.3%), respectively. Subset analyses for OS, IDFS, and DDFS demonstrated benefit across major subgroups. No new safety signals were identified including no new cases of acute myeloid leukemia or myelodysplastic syndrome. CONCLUSION With 3.5 years of median follow-up, OlympiA demonstrates statistically significant improvement in OS with adjuvant olaparib compared with placebo for gBRCA1/2pv-associated EBC and maintained improvements in the previously reported, statistically significant endpoints of IDFS and DDFS with no new safety signals.

Development of a spiritual care education matrix: Factors facilitating/hindering improvement of spiritual care competency in student nurses and midwives. NURSE EDUCATION TODAY 2022; 114:105403.

Abstract
Spiritual care is a fundamental aspect of caring and compassionate nursing/midwifery practice. However, nurses/midwives consistently report feeling unprepared to provide spiritual care for various reasons. A key reason appears to be the lack of structured spiritual care education in undergraduate nursing/midwifery curricula. Between 2016 and 2019, the three-year, European EPICC project ('Enhancing nurses' and midwives' competence in Providing spiritual care through Innovative education and 'Compassionate Care') sought to address gaps in nursing/midwifery competence in spiritual care. A key project output, and the focus of this paper, is the EPICC Gold Standard Matrix for Spiritual Care Education ('EPICC Matrix'), which depicts the complex array of factors hindering/facilitating the development of nursing/midwifery spiritual care competency. The EPICC project followed two major studies that identified factors contributing to nursing/midwifery spiritual care competency development. This evidence, along with the mixed methods focus of the EPICC project to enable co-projection of its outputs informed the development of the EPICC Matrix. The EPICC Matrix was considered to represent 'the cultural, social and political environment in which spiritual care competency develops' in student nurses/midwives. The EPICC Matrix illustrates spiritual care educational considerations during the process of selecting suitable nursing/midwifery students; through the specific aspects of the teaching and learning environment, the student as a person, and the clinical environment in which spiritual care competency develops; and finally, how the student is assessed as competent in providing spiritual care. Recent research supports the use of the EPICC Matrix in undergraduate nursing/midwifery curricula and strengthens the case for support of the other EPICC project outputs, including: the EPICC Spiritual Care Education Standard, EPICC Adoption Toolkit, and the continuation of the EPICC Network. Further testing of the EPICC Matrix to determine its relevance in different cultural/professional contexts within and outside of Europe would be welcomed.

Abstract
Genomic studies have identified recurrent somatic alterations in genes involved in DNA methylation and post-translational histone modifications in acute lymphoblastic leukemia (ALL), suggesting new opportunities for therapeutic interventions. In this study, we identified G9a/EHMT2 as a potential target in T-ALL through the intersection of epigenome-centered shRNA and chemical screens. We subsequently validated G9a with low-throughput CRISPR-Cas9-based studies targeting the catalytic G9a SET-domain and the testing of G9a chemical inhibitors in vitro, 3D, and in vivo T-ALL models. Mechanistically we determined that G9a repression promotes lysosomal biogenesis and autophagic degradation associated with the suppression of sestrin2 (SESN2) and inhibition of glycogen synthase kinase-3 (GSK-3), suggesting that in T-ALL glycolytic dependent pathways are at least in part under epigenetic control. Thus, targeting G9a represents a strategy to exhaust the metabolic requirement of T-ALL cells.

AIMS AND OBJECTIVES To map existing evidence about educational interventions or strategies in nursing and allied healthcare concerning students' and staffs' spiritual care provision. BACKGROUND Spiritual care is an important part of whole person care, but healthcare staff lack competence and awareness of spiritual issues in practice. To rectify this, it is important to identify what educational approaches are most helpful in supporting them to provide spiritual care. DESIGN A scoping review using the PRISMA-ScR checklist. METHOD Searches in the databases CINAHL, MEDLINE, ATLA and ERIC were conducted for papers spanning January 2009-May 2020. Search terms were related to spirituality, spiritual care, education and clinical teaching. Appraisal tools were used. RESULTS From the 2128 potentially relevant papers, 36 were included. The studies were from 15 different countries and involved nurses, physicians and other health-related professions, and both quantitative, qualitative and mixed methods were used. The results are presented in three themes: Understanding of spirituality, Strategies in educational settings, and Strategies in practice settings. The review points to great diversity in the content, lengths and setting of the educational interventions or strategies. CONCLUSIONS Courses in spiritual care should be implemented in curricula in both undergraduate and postgraduate education, and several studies suggest it should be mandatory. Courses should also be available for healthcare staff to raise awareness and to encourage the integration of spiritual care into their everyday practice. There is a need for greater consensus about how spirituality and spiritual care are described in healthcare settings. RELEVANCE TO CLINICAL PRACTICE Spiritual care must be included both in monodisciplinary and multidisciplinary educational settings. The main result of spiritual care courses is in building awareness of spiritual issues and self-awareness. To ensure the provision of spiritual care for patients in healthcare practices, continuing and multidisciplinary education is recommended.

Abstract
BackgroundDigital ulcers(DUs) in systemic sclerosis(SSc) represent a major clinical challenge. There are no recommendations for the local management of SSc-DUs. Systemic therapy is considered the standard of care. However, there is a strong rationale for local approaches to DU by avoiding side effects from systemic therapies. The World Scleroderma Foundation DU Working Group intends to develop evidence-based recommendations for DU management including local, non-surgical treatment(ln-sT).ObjectivesTo summarise the literature on the safety and efficacy of ln-sT for SSc-DUs.MethodsA systematic literature review(SLR) of papers describing the use of ln-sT for DU in SSc was performed up to May 2021 according to the PICO framework. References were independently screened by two reviewers who independently assessed the full text of eligible articles and extracted data.ResultsAmong 790 retrieved references, 12 were included. Median(range) number of patients per study was 9(7–84), mean age ranging from 37 to 62.5 years. In 5(41%) studies a control group was included. Background systemic therapies are summarized in Table 1. The most studied treatment was botulin toxin A(BTA). It was used as hand injection in 3 studies (median dose ranging from 90 to 150 U) and as 50 U single finger injection in 1 study. Healing rate after a median time of 8-49 weeks ranged from 71% to 100%. In 2 studies a reduction in VAS pain was observed from 20% to 100%. Transient muscle weakness was the most common side effect in 10% of patients. Amniotic(Am) and hydrocolloid membranes(HyM) were used in 1 study each. They were associated with a good healing rate, statistically significant for the HyM. Tadalafil 2% cream was studied in 1 study and was associated with a reduction in the median DU number from 1.6 to 1 per patient after a median time of 4 weeks and a reduction by 1.4 point in the 10-mm VAS scale. Vitamin E gel was shown to be associated with a statistically significant reduction in the healing time compared to SoC alone in 1 RCT(13.2 ± 2.7 versus 20.9 ± 3.6 weeks, P=<0.001). Low-level light therapy, hydrodissection and corticosteroid injection and extracorporeal shock wave(ESW) were evaluated in 1 study each. They were all associated with positive outcomes which was statistically significant only for the ESW. The only negative trial examined dimethyl sulfoxide and was associated with local toxicity.Table 1.Characteristics of the studies.TreatmentType of studyPatientsBaseline DUBackground therapy (%) ETA CCB APA PG ARB ACE-I PDE-5i ISFollow-up (weeks)Healing rate(%)*Pain Reduction (VAS/10)ComparatorHydrodissection and corticosteroid injectionP1202334.4Rheumatoid ArthritisTadalafil 2% Vitamin E gelRRCT15131.6(1)3.5±2.30462700130704 241(1)Reduced time to heal**1.4SoCAmHyMRP67310001002800002817033143810090**SoCBTAMedian 90 U per handHigh-concentration hand100 U non-dominant handSingle finger 50 URRPP772010314571140718558551008514201001414718 4981277717510020%100%Untreated CHLow-level light therapyP8102537025378100ESWP9493355661144441**1.31Dimethyl sulfoxideDBRCT84No change, skin toxicity with 70% formulation*Unless otherwise stated. **Statistically significant.

Abstract
BackgroundManagement of digital ulcers (DUs) in systemic sclerosis (SSc) is a major clinical challenge. To date, systemic therapy is generally considered as the ‘standard of care’ for significant SSc-DUs. However, there is a strong rationale to develop local approaches to DUs, to avoid side effects from systemic therapies. World Scleroderma Foundation DU Working Group intends to develop practical, evidence-based recommendations for DU management including local, Surgical Treatment (L-ST).ObjectivesTo summarize the literature on the safety and efficacy of L-ST for SSc-DUs.MethodsA systematic literature review (SLR) was conducted up to May 2021. According to the PICO framework, eligibility criteria were defined and original research articles about surgical treatment of SSc DUs in adult patients were included. References were independently screened by 2 reviewers who assessed the full text of eligible articles and extracted data.ResultsThirteen eligible articles out of 790 total publications were identified (Table 1). Due to the paucity of randomized controlled trials of surgical treatments for SSc-DU, we included retrospective studies and case series with at least 4 patients. Autologous fat (adipose tissue AT) grafting was the surgical modality mostly identified (7 studies of which 1 RCT and 6 prospective open label single arm). The healing rate (HR) with autologous fat grafting (4 studies) ranged from 66-100 %. In the RCT, two age and sex matched groups were included, adipose tissue (AT)group (n=25 pts) and sham procedure (SP) group (n=13), DU healing was reported in 23/25 in AT group versus 1/13 in the SP group in 8 wks, (p<0.0001), 12 pts in the SP group, received rescue AT injection, all of them healed after 8 wks. Three studies reported autologous adipose-derived stromal vascular fraction(SVF) grafting and the HR ranged from 32-60%, followed up to 12 months. Transient edema and paresthesia were reported in 2 studies, and amputation in 2 ulcers in 1 study, and no complications were reported in other studies. Surgical sympathectomy was reported in 3 studies, with a median healing rate of 81%. Bone marrow derived cell transplantation in a single study showed 87% healing rate over (4-24 wks). Two surgical studies (of direct microsurgical revascularization N=4, and microsurgical arteriolysis, N=6), showed 100% healing of ulcers, no complications reported.Table 1.Characteristics of the extracted studies.StudydesignPatients (n)Baseline DU (n)Background therapy (%)Follow-upOutcomeHealed ulcers(%) Adipose tissue graftAutologous fat graftp9.15PG, CCB—100ETA 26PDE-5i 138-12 wks66Adipose tissue graftingRCT25 case13- Ctr25-case13- CtrPG- 100CCB 1008 wks92-case7-CtrAdipose tissue implantp1515no therapy7 wks100Adipose tissue graftp129PG,CCB-100ETA6 month88adipose derived SVFp1215PDE-5i, ccb, PG allowed22m6Adipose derived SVFp1215CCB 50ETA166 m63 Adipose derived SVFp1819CCB 50PG 27ETA 5IS 7124 wks32SympathectomySympathectomyR611CCB-10020 m81SympathectomyR1335PGCCBAPA35Sympathectomy, vascular bypass (+vein graftR1726Ccb 35APA 47PDE-i5 589 m100Bone marrow derived cells transplantation)p88PG-6236 m87Direct microsurgical revascularizationR44m100Limited microsurgical arteriolysisR61712 m100SVF =stromal vascular fraction P = prospective.

Abstract
BackgroundDigital ulcers (DU) are common in systemic sclerosis (SSc) and associated with reduced survival, high morbidity and poor quality of life. Recommendations have previously been proposed for DU management yet there remains significant unmet patient need. Therefore the World Scleroderma Foundation DU Working Group intends to develop practical evidence based recommendations for DU management.ObjectivesTo summarise data on efficacy and safety of systemic treatments for SSc DU.MethodsA systematic literature review to May 2021 was performed. PubMed, MEDLINE, Embase, Web of Science, Cochrane Library, Emcare (OVID) and Academic Search Premier databases were searched for original studies on adult patients with SSc DU treated with systemic pharmacological treatment. Based on the PICO framework, eligibility criteria were defined and references were independently screened by two reviewers. Reviewers independently assessed the full text of eligible articles. Owing to interstudy heterogeneity narrative summaries were used to present data.ResultsThe search strategy identified 1271 references of which 45 eligible articles were included. Seventeen studies were randomised placebo controlled trials (RCT) pertaining to PDE5 antagonists (PDE5i) (n=3), endothelin receptor antagonists (ERA) (n=3), prostanoids (n=7), antiplatelet agents (n=1) and other (n=3) (Table 1). No head to head RCT was retrieved. All other studies were observational studies (OBS). Studies were highly heterogeneous with application of differing definition of DU, variable study eligibility criteria, clinical endpoints and follow up periods. This limited the calculation of effect size and comparison across studies.Table 1.Characteristics of placebo controlled randomised controlled trialsAuthor YearInterventionnFollow upOutcomeFavours interventionHachulla 2016Sildenafil8312 weeksTime to DU healing-Andrigueti 2017Sildenafil4112 weeksDU healing+Shenoy 2010Tadalafil246 weeksNew DU+Khanna 2016Macitentan55416 weeksNew DU-Matucci-Cerinic 2011Bosentan18832 weeksNew DU Time to healing of DU+-Korn 2004Bosentan12212 weeksNew DU+Kawald 2008IV iloprost5012 monthsDU healing-Wigley 1992IV iloprost3510 weeksDU healing+Wigley 1994IV iloprost739 weeks50% reduction in DU score-Seibold 2017Treprostinil14820 weeksNet DU burden-Vayssairat 1999Beraprost10725 weeks% patients with new DU-Denton 2017Selexipag7412 weeksNumber of new DU DU healing-Lau 1993Cicaprost334 weeksNumber of DU-Abou-Raya 2008Atorvastatin844 monthsNumber of DU+Au 2010Cyclophosphamide15812 monthsNumber of patients with DU-Beckett 1984Dipyridamole / aspirin412 yearsChange in general SSc-Nagaraja 2019Riociguat1732 weeksNet DU burden-+ significantly superior to comparator- non significantly different from comparatorDU: digital ulcers IV: intravenous SSc: systemic sclerosisSeveral RCT found improved DU healing with treatment: two with PDE5i, one with iloprost and one showed improved DU healing and prevention with atorvastatin. Two RCT demonstrated effective prevention of new DU with bosentan. OBS studies with a total of 621 patients showed variable improvements in the healing of DU with CCB, PDE5i, ERA, statins, N-acetylcysteine, prostanoids and ketanserin and prevention of new DU with ERA.Regarding safety, all treatments were generally tolerated with few serious adverse events. Treatment was ceased in 6.25-17.5% of patients in RCT due to treatment related side effects.ConclusionDespite several studies assessing the efficacy and safety of systemic pharmacological treatment of SSc DU, it is not possible to draw solid conclusions due to study heterogeneity. Small RCT have shown treatment benefit with PDE5i, iloprost and atorvastatin. Large studies demonstrated effective prevention of new DU with bosentan. Our results highlight the urgent need for improved clinical trial design to generate more robust evidence and novel therapies to guide the management SSc DU.AcknowledgementsThis work was supported by the World Scleroderma Foundation.Disclosure of InterestsNancy Maltez: None declared, Laura Ross: None declared, Michael Hughes Speakers bureau: Actelion Pharmaceuticals, Eli Lilly and Pfizer outside of the submitted work., Jan Schoones: None declared, Murray Baron: None declared, Lorinda Chung Consultant of: Eicos, Corrado Campochiaro: None declared, Yossra A.

TRIM8 modulates the EWS/FLI oncoprotein to promote survival in Ewing sarcoma. Cancer Cell 2021; 39:1262-1278.e7.

Abstract
Fusion-transcription factors (fusion-TFs) represent a class of driver oncoproteins that are difficult to therapeutically target. Recently, protein degradation has emerged as a strategy to target these challenging oncoproteins. The mechanisms that regulate fusion-TF stability, however, are generally unknown. Using CRISPR-Cas9 screening, we discovered tripartite motif-containing 8 (TRIM8) as an E3 ubiquitin ligase that ubiquitinates and degrades EWS/FLI, a driver fusion-TF in Ewing sarcoma. Moreover, we identified TRIM8 as a selective dependency in Ewing sarcoma compared with >700 other cancer cell lines. Mechanistically, TRIM8 knockout led to an increase in EWS/FLI protein levels that was not tolerated. EWS/FLI acts as a neomorphic substrate for TRIM8, defining the selective nature of the dependency. Our results demonstrate that fusion-TF protein stability is tightly regulated and highlight fusion oncoprotein-specific regulators as selective therapeutic targets. This study provides a tractable strategy to therapeutically exploit oncogene overdose in Ewing sarcoma and potentially other fusion-TF-driven cancers.

Abstract
The development and survival of cancer cells require adaptive mechanisms to stress. Such adaptations can confer intrinsic vulnerabilities, enabling the selective targeting of cancer cells. Through a pooled in vivo short hairpin RNA (shRNA) screen, we identified the adenosine triphosphatase associated with diverse cellular activities (AAA-ATPase) valosin-containing protein (VCP) as a top stress-related vulnerability in acute myeloid leukemia (AML). We established that AML was the most responsive disease to chemical inhibition of VCP across a panel of 16 cancer types. The sensitivity to VCP inhibition of human AML cell lines, primary patient samples, and syngeneic and xenograft mouse models of AML was validated using VCP-directed shRNAs, overexpression of a dominant-negative VCP mutant, and chemical inhibition. By combining mass spectrometry-based analysis of the VCP interactome and phospho-signaling studies, we determined that VCP is important for ataxia telangiectasia mutated (ATM) kinase activation and subsequent DNA repair through homologous recombination in AML. A second-generation VCP inhibitor, CB-5339, was then developed and characterized. Efficacy and safety of CB-5339 were validated in multiple AML models, including syngeneic and patient-derived xenograft murine models. We further demonstrated that combining DNA-damaging agents, such as anthracyclines, with CB-5339 treatment synergizes to impair leukemic growth in an MLL-AF9-driven AML murine model. These studies support the clinical testing of CB-5339 as a single agent or in combination with standard-of-care DNA-damaging chemotherapy for the treatment of AML.

Abstract
The core cohesin subunit STAG2 is recurrently mutated in Ewing sarcoma but its biological role is less clear. Here, we demonstrate that cohesin complexes containing STAG2 occupy enhancer and polycomb repressive complex (PRC2)-marked regulatory regions. Genetic suppression of STAG2 leads to a compensatory increase in cohesin-STAG1 complexes, but not in enhancer-rich regions, and results in reprogramming of cis-chromatin interactions. Strikingly, in STAG2 knockout cells the oncogenic genetic program driven by the fusion transcription factor EWS/FLI1 was highly perturbed, in part due to altered enhancer-promoter contacts. Moreover, loss of STAG2 also disrupted PRC2-mediated regulation of gene expression. Combined, these transcriptional changes converged to modulate EWS/FLI1, migratory, and neurodevelopmental programs. Finally, consistent with clinical observations, functional studies revealed that loss of STAG2 enhances the metastatic potential of Ewing sarcoma xenografts. Our findings demonstrate that STAG2 mutations can alter chromatin architecture and transcriptional programs to promote an aggressive cancer phenotype.

Abstract
AIMS The aim of this study was to develop a consensus-based Spiritual Care Education Standard for undergraduate N/M students to use in undergraduate programmes. DESIGN Mixed methods were used consisting of qualitative and quantitative methods based on the principles of Delphi research. METHODS The sample consisted of a total of 58 (N = 58) participants from 21 European countries. Data collection was conducted from June 2017 - February 2019 and took place in facilitated iterative action learning cycles and online surveys. Data were analysed by descriptive statistics and qualitative analysis. Consensus was stated by >90% agreement. RESULTS The process resulted in an EPICC Spiritual Care Education Standard consisting of the following four spiritual care competences: Intrapersonal spirituality, Interpersonal spirituality, Spiritual care: assessment and planning, Spiritual care: intervention and evaluation. For every competence, learning outcomes were described in knowledge, skills and attitudes. CONCLUSION This Standard guides N/M spiritual care education, student assessment and research. It can be the starting point for discussing spiritual care competences in other healthcare professions. Follow-up research should focus on implementation of the standard and on assessment of students' spiritual competence. IMPACT The Standard guides curriculum and programme development. The Standard guides students in performing their learning process. The Standard provides a frame of reference for policy making and follow-up research.

Abstract
Continuous sampling provides the most complete data set for behavioral research; however, it often requires a prohibitive investment of time and labor. The objectives of this study were to validate behavioral observation methods of young broiler chickens using 1) 7 scan sampling intervals (0.5, 1, 3, 5, 10, 15, and 30 min) and 2) an automated tracking software program (EthoVision XT 14) compared to continuous behavioral observation, considered the gold standard for behavior observation. Ten 19-day-old Ross 708 broiler cockerels were included in this study. All behavior was video recorded over an 8-h period, and data were collected using a continuous sampling methodology. The same video files were utilized for analysis for scan sampling and automated tracking software analysis. For both analyses, the following criteria were used to identify which method accurately reflected the true duration and frequency for each behavior, as determined by continuous observation: R2 ≥ 0.9, slope was not different from 1 (P > 0.05), and intercept was not different from 0 (P > 0.05). Active, eating, drinking, and maintenance behaviors were accurately estimated with 0.5-min scan sample intervals. Active, inactive, eating, and maintenance behaviors were accurately estimated with 1-min scan sample intervals. Inactive behavior was accurately estimated with 5-min scan sample intervals. The remainder of sampling intervals examined did not provide accurate estimates, and no scan sampling interval accurately estimated the number of behavior bouts. The automated tracking software was able to accurately detect true duration of inactive behavior but was unable to accurately detect activity. The results of this study suggest that high-frequency behaviors can be accurately observed with instantaneous scan sampling up to 1-min intervals. Automated tracking software can accurately identify inactivity in young broiler chickens, but further behavior identification will require refinement.

Abstract
Spleen tyrosine kinase (SYK) is a nonmutated therapeutic target in acute myeloid leukemia (AML). Attempts to exploit SYK therapeutically in AML have shown promising results in combination with chemotherapy, likely reflecting induced mechanisms of resistance to single-agent treatment in vivo. We conducted a genome-scale open reading frame (ORF) resistance screen and identified activation of the RAS-MAPK-ERK pathway as one major mechanism of resistance to SYK inhibitors. This finding was validated in AML cell lines with innate and acquired resistance to SYK inhibitors. Furthermore, patients with AML with select mutations activating these pathways displayed early resistance to SYK inhibition. To circumvent SYK inhibitor therapy resistance in AML, we demonstrate that a MEK and SYK inhibitor combination is synergistic in vitro and in vivo. Our data provide justification for use of ORF screening to identify resistance mechanisms to kinase inhibitor therapy in AML lacking distinct mutations and to direct novel combination-based strategies to abrogate these. SIGNIFICANCE: The integration of functional genomic screening with the study of mechanisms of intrinsic and acquired resistance in model systems and human patients identified resistance to SYK inhibitors through MAPK signaling in AML. The dual targeting of SYK and the MAPK pathway offers a combinatorial strategy to overcome this resistance.This article is highlighted in the In This Issue feature, p. 161.

Abstract
Abstract
Interlaboratory validation studies have been performed on 2 methods for the determination of chlormequat (CLQ) and mepiquat (MPQ). Both methods used identical extraction procedures and stable isotope internal standardization but differed in the use of liquid chromatography/mass spectrometry (LC/MS) or LC/tandem mass spectrometry (LC/MS/MS) for the determination, the amount of internal standard used, and the expected limit of detection. After addition of deuterated internal standards, CLQ and MPQ were extracted with methanol–water and determined by LC/MS or LC/MS/MS with positive electrospray ionization. Eight European laboratories participated in the LC/MS method study, analyzing mushroom, pear, wheat flour, and fruit puree with residues of CLQ in the range 0.040–1.19 mg/kg and of MPQ in the range 0.041–0.39 mg/kg. For CLQ, the Horwitz ratio (HoRat) values for individual test materials/levels were in the range 0.85–1.13 with amean of 1.00, showing good method performance. For MPQ, the Ho values for mushroom, pear (both levels), and wheat flour were in the range 0.83–0.94, again indicating good method performance. For the determination of MPQ in infant food (fruit puree) at 0.041 mg/kg, the Ho was 1.7 when a value of 0 reported by one participant was excluded. In the LC/MS/MS study, in which 11 laboratories participated, a separate sample set was analyzed with residues of CLQ in the range 0.007–1.03 mg/kg and of MPQ in the range 0.008–0.72 mg/kg. Ho values for CLQ were in the range 0.27–1.36 and for MPQ in the range 0.51–2.10, all corresponding to acceptable method performance.

Exploiting an Asp-Glu "switch" in glycogen synthase kinase 3 to design paralog-selective inhibitors for use in acute myeloid leukemia. Sci Transl Med 2019.

Abstract
Glycogen synthase kinase 3 (GSK3), a key regulatory kinase in the wingless-type MMTV integration site family (WNT) pathway, is a therapeutic target of interest in many diseases. Although dual GSK3α/β inhibitors have entered clinical trials, none has successfully translated to clinical application. Mechanism-based toxicities, driven in part by the inhibition of both GSK3 paralogs and subsequent β-catenin stabilization, are a concern in the translation of this target class because mutations and overexpression of β-catenin are associated with many cancers. Knockdown of GSK3α or GSK3β individually does not increase β-catenin and offers a conceptual resolution to targeting GSK3: paralog-selective inhibition. However, inadequate chemical tools exist. The design of selective adenosine triphosphate (ATP)-competitive inhibitors poses a drug discovery challenge due to the high homology (95% identity and 100% similarity) in this binding domain. Taking advantage of an Asp133→Glu196 "switch" in their kinase hinge, we present a rational design strategy toward the discovery of paralog-selective GSK3 inhibitors. These GSK3α- and GSK3β-selective inhibitors provide insights into GSK3 targeting in acute myeloid leukemia (AML), where GSK3α was identified as a therapeutic target using genetic approaches. The GSK3α-selective compound BRD0705 inhibits kinase function and does not stabilize β-catenin, mitigating potential neoplastic concerns. BRD0705 induces myeloid differentiation and impairs colony formation in AML cells, with no apparent effect on normal hematopoietic cells. Moreover, BRD0705 impairs leukemia initiation and prolongs survival in AML mouse models. These studies demonstrate feasibility of paralog-selective GSK3α inhibition, offering a promising therapeutic approach in AML.

Abstract
Gallbladder mucocele (GBM) is a common extra-hepatic biliary syndrome in dogs with death rates ranging from 7 to 45%. Therefore, the aim of this study was to identify the association of survival with variables that could be utilized to improve clinical decisions. A total of 1194 dogs with a gross and histopathological diagnosis of GBM were included from 41 veterinary referral hospitals in this retrospective study. Dogs with GBM that demonstrated abnormal clinical signs had significantly greater odds of death than subclinical dogs in a univariable analysis (OR, 4.2; 95% CI, 2.14-8.23; P<0.001). The multivariable model indicated that categorical variables including owner recognition of jaundice (OR, 2.12; 95% CI, 1.19-3.77; P=0.011), concurrent hyperadrenocorticism (OR 1.94; 95% CI, 1.08-3.47; P=0.026), and Pomeranian breed (OR, 2.46; 95% CI 1.10-5.50; P=0.029) were associated with increased odds of death, and vomiting was associated with decreased odds of death (OR, 0.48; 95% CI, 0.30-0.72; P=0.001). Continuous variables in the multivariable model, total serum/plasma bilirubin concentration (OR, 1.03; 95% CI, 1.01-1.04; P<0.001) and age (OR, 1.17; 95% CI, 1.08-1.26; P<0.001), were associated with increased odds of death. The clinical utility of total serum/plasma bilirubin concentration as a biomarker to predict death was poor with a sensitivity of 0.61 (95% CI, 0.54-0.69) and a specificity of 0.63 (95% CI, 0.59-0.66). This study identified several prognostic variables in dogs with GBM including total serum/plasma bilirubin concentration, age, clinical signs, concurrent hyperadrenocorticism, and the Pomeranian breed. The presence of hypothyroidism or diabetes mellitus did not impact outcome in this study.

Abstract
OBJECTIVE There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings. RESEARCH DESIGN AND METHODS Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years. RESULTS At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects. CONCLUSIONS Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Abstract
BACKGROUND Dietetic models of care at Logan Hospital changed from all patients with a confirmed stroke receiving dietitian assessment (Old pathway) to only those patients screened as high-nutritional-risk (Modified pathway). However, it was unknown whether all low-nutritional-risk patients who were indicated for dietitian assessment for nutrition support actually received assessment. This pre-post retrospective study evaluated whether the Old pathway and the Modified pathway were equally effective in identifying low-nutritional-risk stroke patients who were indicated for dietitian assessment and compared the time spent providing Dietetic care. METHODS For both pathways, medical charts were reviewed for low-nutritional-risk patients admitted between December 2012 and November 2017 with a confirmed stroke, who were given a standard food and fluid diet code and scored MST < 2 (Malnutrition Screening Tool) on admission. Data collected included demographics, anthropometrics, malnutrition assessment, dietetic intervention and time spent caring for patients. Malnutrition-related clinical indicators were used to classify patients as either Dietitian Assessment for Nutrition Support Indicated or Not Indicated. RESULTS Low-nutritional-risk patients were similar on the Old (n = 180) and Modified (n = 206) pathways [mean (SD) 66 (13) years, 63% male, 4% malnutrition]. Those classified as Dietitian Assessment for Nutrition Support Indicated (n = 61 of 180) were older, had a longer length of stay (P < 0.05), and were all identified by the Dietitian on both pathways. Ten minutes less dietetic time per patient was required on the Modified pathway (P < 0.001). CONCLUSIONS The Modified Nutrition Stroke pathway performed more efficiently than the Old pathway and was equally effective at ensuring that stroke patients who were determined as being low-nutritional-risk received dietitian assessment during admission if indicated.

A Combination CDK4/6 and IGF1R Inhibitor Strategy for Ewing Sarcoma. Clin Cancer Res 2018; 25:1343-1357.

Abstract
PURPOSE Novel targeted therapeutics have transformed the care of subsets of patients with cancer. In pediatric malignancies, however, with simple tumor genomes and infrequent targetable mutations, there have been few new FDA-approved targeted drugs. The cyclin-dependent kinase (CDK)4/6 pathway recently emerged as a dependency in Ewing sarcoma. Given the heightened efficacy of this class with targeted drug combinations in other cancers, as well as the propensity of resistance to emerge with single agents, we aimed to identify genes mediating resistance to CDK4/6 inhibitors and biologically relevant combinations for use with CDK4/6 inhibitors in Ewing. EXPERIMENTAL DESIGN We performed a genome-scale open reading frame (ORF) screen in 2 Ewing cell lines sensitive to CDK4/6 inhibitors to identify genes conferring resistance. Concurrently, we established resistance to a CDK4/6 inhibitor in a Ewing cell line. RESULTS The ORF screen revealed IGF1R as a gene whose overexpression promoted drug escape. We also found elevated levels of phospho-IGF1R in our resistant Ewing cell line, supporting the relevance of IGF1R signaling to acquired resistance. In a small-molecule screen, an IGF1R inhibitor scored as synergistic with CDK4/6 inhibitor treatment. The combination of CDK4/6 inhibitors and IGF1R inhibitors was synergistic in vitro and active in mouse models. Mechanistically, this combination more profoundly repressed cell cycle and PI3K/mTOR signaling than either single drug perturbation. CONCLUSIONS Taken together, these results suggest that IGF1R inhibitors activation is an escape mechanism to CDK4/6 inhibitors in Ewing sarcoma and that dual targeting of CDK4/6 inhibitors and IGF1R inhibitors provides a candidate synergistic combination for clinical application in this disease.

Abstract
BACKGROUND There is a paucity of studies examining the beneficial effects of fish consumption on cardiovascular diseases (CVDs) among adults with diabetes, who experience a substantially high risk of CVDs. METHODS AND RESULTS We analyzed the data of 1136 adults with diabetes mellitus aged 18 years and older who participated in the National Health and Nutrition Examination Survey, 1988-1994, and were followed up through December 31, 2010. We used Cox regression to estimate the adjusted hazard ratios (HRs) for the relative risk across the levels of fish consumption. A total of 698 deaths were recorded at the end of 11,465 person-years follow-up with a mortality rate of 60.88 per 1000 person-years. CVDs were listed as a contributing cause for 326 deaths, thus accounting for 46.4% of total deaths. Stroke-specific mortality rate among patients who ate fish less than once a week was more than twice as high as that among patients who ate fish more than twice a week, 6.23 vs. 2.36 per 1000 person-years, respectively. The corresponding CVD-specific rate was 34.38 vs. 22.99 per 1000 person-years, respectively. The adjusted HRs of death due to stroke were 1.00 (reference), 0.55 (95% confidence interval = 0.28-1.07), and 0.30 (0.11-0.80) among patients who ate fish <1, 1-2, and 2 + times a week, and the corresponding HRs of death due to CVDs were 1.00 (reference), 0.78 (0.60-1.02), and 0.69 (0.50-0.96), respectively. CONCLUSIONS A high consumption of fish was associated with a low risk of death due to CVDs, especially stroke, among adults with diabetes.

Nursing and midwifery students' perceptions of spirituality, spiritual care, and spiritual care competency: A prospective, longitudinal, correlational European study. NURSE EDUCATION TODAY 2018; 67:64-71. [PMID: 29763841 DOI: 10.1016/j.nedt.2018.05.002] [Citation(s) in RCA: 59] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/07/2017] [Revised: 04/04/2018] [Accepted: 05/01/2018] [Indexed: 05/11/2023]
Abstract
BACKGROUND Nurses and midwives care for people at some of the most vulnerable moments of their lives, so it is essential that they have the skills to give care which is compassionate, dignified, holistic and person-centred. Holistic care includes spiritual care which is concerned with helping people whose beliefs, values and sense of meaning, purpose and connection is challenged by birth, illness or death. Spiritual care is expected of nurses/midwives but they feel least prepared for this part of their role. How nursing and midwifery students can be prepared for spiritual care is the focus of this study. OBJECTIVES 1. To describe undergraduate nursing and midwifery student's perceptions of spirituality/spiritual care, their perceived competence in giving spiritual care and how these perceptions change over time. 2. To explore factors contributing to development of spiritual care competency. METHODS Prospective, longitudinal, multinational, correlational survey design. A convenience sample of 2193 undergraduate nursing and midwifery students (69% response rate, dropping to 33%) enrolled at 21 universities in eight countries completed questionnaires capturing demographic data (purpose designed questionnaire) and measuring perception of spirituality/spiritual care (SSCRS), spiritual care competency (SCCS), spiritual wellbeing (JAREL) and spiritual attitude and involvement (SAIL) on 4 occasions (start of course n = 2193, year 2 n = 1182, year 3 n = 736, end of course n = 595) between 2011 and 2015. Data were analysed using descriptive, bivariate and multivariate analyses as appropriate. RESULTS Perceived competency increased significantly over the course of students' study which they attributed to caring for patients, events in their own lives and teaching/discussion in university. Two factors were significantly correlated with perceived spiritual care competency: perception of spirituality/spiritual care, where a broad view was preferable, and personal spirituality, where high spiritual wellbeing (JAREL) and spiritual attitude and involvement (SAIL) scores were preferable. CONCLUSIONS We have provided the first international evidence that perceived spiritual care competence is developed in undergraduate nursing and midwifery students and that students' perceptions of spirituality and personal spirituality contribute to that development. Implications for teaching and learning and student selection are discussed. The study is limited by attrition which is common in longitudinal research.

Improving health care student attitudes toward older adults through educational interventions: A systematic review. GERONTOLOGY & GERIATRICS EDUCATION 2018; 39:193-213. [PMID: 27935437 DOI: 10.1080/02701960.2016.1267641] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 05/25/2023]
Abstract
Educational institutions should aim to positively influence the attitudes of future health care practitioners toward older patients to ensure the provision of quality patient care. This systematic review of the literature aims to determine the effectiveness of educational interventions designed to improve health care student behaviors and/or attitudes toward older people. The 29 studies included in this review utilized a variety of interventions, methods, and measurement tools. The most common type of educational intervention incorporated interaction with real patients. Few studies evaluated the impact of interventions on behavior; therefore, more observational studies are required. Overall interventions incorporating interactions with real patients who are independently living had a positive impact on student attitudes toward older adults. Clinically focused placements with patients who are ill may still have a place in the development of the patient-centered interview and assessment skills, along with improving confidence and competence, despite not having a favorable impact on attitudes.

CRISPR-Cas9 screen reveals a MYCN-amplified neuroblastoma dependency on EZH2. J Clin Invest 2017; 128:446-462. [PMID: 29202477 DOI: 10.1172/jci90793] [Citation(s) in RCA: 97] [Impact Index Per Article: 13.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2016] [Accepted: 10/24/2017] [Indexed: 12/26/2022] Open
Abstract
Pharmacologically difficult targets, such as MYC transcription factors, represent a major challenge in cancer therapy. For the childhood cancer neuroblastoma, amplification of the oncogene MYCN is associated with high-risk disease and poor prognosis. Here, we deployed genome-scale CRISPR-Cas9 screening of MYCN-amplified neuroblastoma and found a preferential dependency on genes encoding the polycomb repressive complex 2 (PRC2) components EZH2, EED, and SUZ12. Genetic and pharmacological suppression of EZH2 inhibited neuroblastoma growth in vitro and in vivo. Moreover, compared with neuroblastomas without MYCN amplification, MYCN-amplified neuroblastomas expressed higher levels of EZH2. ChIP analysis showed that MYCN binds at the EZH2 promoter, thereby directly driving expression. Transcriptomic and epigenetic analysis, as well as genetic rescue experiments, revealed that EZH2 represses neuronal differentiation in neuroblastoma in a PRC2-dependent manner. Moreover, MYCN-amplified and high-risk primary tumors from patients with neuroblastoma exhibited strong repression of EZH2-regulated genes. Additionally, overexpression of IGFBP3, a direct EZH2 target, suppressed neuroblastoma growth in vitro and in vivo. We further observed strong synergy between histone deacetylase inhibitors and EZH2 inhibitors. Together, these observations demonstrate that MYCN upregulates EZH2, leading to inactivation of a tumor suppressor program in neuroblastoma, and support testing EZH2 inhibitors in patients with MYCN-amplified neuroblastoma.

Abstract
This research aimed to gain an understanding of the psychosocial support needs of older patients in the out-of-hospital setting from the perspective of paramedics. Specifically, we investigate if and how paramedics are able to meet the needs of older adults, and the barriers preventing them from achieving this. This study was a cross-sectional study utilizing a sequential design with both quantitative and qualitative methodologies. All participants agreed or strongly agreed that older patients have needs beyond the physical and that they would like to do more for older patients. Paramedics discussed that psychosocial support issues are rarely in isolation and straightforward but were often coupled with broader, longer term physical health and social support issues. They would like to be able to do more for patients but feel hamstrung by lack of time, resources, and know-how.
