RESUMO

Entrustable professional activities (EPAs) have been proposed as a practical framework for the implementation of competency-based education. As veterinary education moves toward a competency-based approach, core EPAs provide a context for assessment of workplace activities. This article reports on the development of eight core clinical EPAs for veterinary education created through multi-institutional collaboration, with international input from veterinary educators and veterinary educational leaders. These core EPAs are intended as minimal expectations for clinical activities that should be assessed for every graduate of Association of American Veterinary Medical Colleges member institutions. Adoption of the core EPAs and the associated Competency-Based Veterinary Education (CBVE) framework by veterinary schools is intended to promote Day One graduate competence and thereby enhance patient care and client service.

RESUMO

Competency-based medical education is an educational innovation implemented in health professions worldwide as a means to ensure graduates meet patient and societal needs. The focus on student-centered education and programmatic outcomes offers a series of benefits to learners, institutions and society. However, efforts to establish a shared, comprehensive competency-based framework in veterinary education have lagged. This article reports on the development and outcome of a competency-based veterinary education (CBVE) framework created through multi-institutional collaboration with international input from veterinary educators and veterinary educational leaders. The CBVE Framework is designed to reflect the competencies expected of new graduates from member institutions of the Association of American Veterinary Medical Colleges (AAVMC). The CBVE Framework consists of nine domains of competence and 32 competencies, each supplemented with illustrative sub-competencies to guide veterinary schools in implementing competency-based education in their local context. The nine domains of competence are: clinical reasoning and decision-making; individual animal care and management; animal population care and management; public health; communication; collaboration; professionalism and professional identity; financial and practice management; and scholarship. Developed through diverse input to facilitate broad adoption, the CBVE Framework provides the foundation for competency-based curricula and outcomes assessment in veterinary education internationally. We believe that other groups seeking to design a collective product for broad adoption might find useful the methods used to develop the CBVE Framework, including establishing expertise diversity within a small-to-medium size working group, soliciting progressive input and feedback from stakeholders, and engaging in consensus building and critical reflection throughout the development process.

RESUMO

Purpose: Despite the adoption of competency-based education in some veterinary schools over the past 15 years, only recently has a concerted effort been directed toward this in veterinary education internationally.Methods: In 2015, educational leaders from the Association of American Veterinary Medical Colleges (AAVMC) member schools came together with a strong call to action to create shared tools for clinical competency assessment.Results: This resulted in the formation of the AAVMC Competency-Based Veterinary Education (CBVE) Working Group, which then embarked on the creation of a shared competency framework and the development of eight core entrustable professional activities (EPAs) linked to this framework.Conclusions: This paper will report on the development of these EPAs and their integration with the concurrently-developed CBVE Framework.

RESUMO

In this work, we explore the interactions between the ionic liquid 1-ethyl-3-methylimidazolim acetate and different inorganic salts belonging to two different cation families, those based on ammonium and others based on sodium. NMR and Raman spectroscopy are used to screen for changes in the molecular environment of the ions in the ionic liquid + inorganic salt mixtures as compared to pure ionic liquid. The ion self-diffusion coefficients are determined from NMR data, allowing the discussion of the ionicity values of the ionic liquid + inorganic salt mixtures calculated using different methods. Our data reveal that preferential interactions are established between the ionic liquid and ammonium-based salts, as opposed to sodium-based salts. Computational calculations show the formation of aggregates between the ionic liquid and the inorganic salt, which is consistent with the spectroscopic data, and indicate that the acetate anion of the ionic liquid establishes preferential interactions with the ammonium cation of the inorganic salts, leaving the imidazolium cation less engaged in the media.

RESUMO

BACKGROUND: Migrant and seasonal farmworking (MSFW) women patients experience substantially more intimate partner violence (IPV) than the general population, but few health-care providers screen patients for IPV. While researchers have examined screening practices in health-care settings, none have exclusively focused on MSFW women. OBJECTIVE: The aim of this phenomenological study was to explore the experiences of health-care providers who have screened for and/or addressed IPV with MSFW women patients. DESIGN: Researchers utilized descriptive phenomenology to capture the lived experiences of these health-care providers. Data were analysed using Colaizzi's seven-stage framework. SETTING AND PARTICIPANTS: Interviews were conducted with nine female participants - all of whom: (i) were clinically active health-care providers within the MSFW community, (ii) were bilingual in English and Spanish or had access to a translator, (iii) had treated MSFW patients who had experienced IPV and (iv) were at least 18 years of age. RESULTS: Participants' experiences were reflected in four emergent themes: (i) provider-centered factors, (ii) patient-centered factors, (iii) clinic-centered factors and (iv) community-centered factors. Participants described barriers to establish routine IPV assessment, decrease patient ambivalence and increase on-site support and community resources. DISCUSSION AND CONCLUSIONS: This study aimed to generate a greater understanding of the experiences of health-care providers with screening for and addressing IPV with MSFW patients. Implications and recommendations for research, clinical practice and policy are provided.

RESUMO

New findings supporting the stability of the superoxide ion, O2˙(-), in the presence of the phosphonium cation, [P6,6,6,14](+), are presented. Extended electrochemical investigations of a series of neat phosphonium-based ILs with different anions, including chloride, bis(trifluoromethylsulfonyl)imide and dicyanamide, demonstrate the chemical reversibility of the oxygen reduction process. Quantum chemistry calculations show a short intermolecular distance (r = 3.128 Å) between the superoxide ion and the phosphonium cation. NMR experiments have been performed to assess the degree of long term degradation of [P6,6,6,14](+), in the presence of superoxide and peroxide species, showing no chemically distinct degradation products of importance in reversible air cathodes.

RESUMO

Migrant and seasonal farm working (MSFW) women report higher rates of intimate partner violence (IPV) as compared to the national average (Hazen and Soriano in Violence Against Women 13:562-582, 2007). Although prior researchers have indicated that implementing IPV screenings in healthcare settings significantly increases rates of identifying IPV (Nelson et al. in Ann Intern Med 156:1-17, 2012; Ramsay et al. in Br Med J 325:314-318, 2002); many providers opt not to screen (Jonassen and Mazor in Acad Med 78(10):S20-S23, 2003; Smith et al. in Fam Community Health 20:1-18, 1998). The purpose of this policy brief is to review previous research related to IPV among MSFW women and, based on the findings, recommend policies that may help to improve the detection, intervention, resources, and available science with respect to this underserved population.

RESUMO

The implementation of competency-based curricula within the health sciences has been an important paradigm shift over the past 30 years. As a result, one of the five strategic goals recommended by the North American Veterinary Medical Education Consortium (NAVMEC) report was to graduate career-ready veterinarians who are proficient in, and have the confidence to use, an agreed-upon set of core competencies. Of the nine competencies identified as essential for veterinary graduates, seven could be classified as professional or non-technical competencies: communication; collaboration; management (self, team, system); lifelong learning, scholarship, value of research; leadership; diversity and multicultural awareness; and adaptation to changing environments. Traditionally, the professional competencies have received less attention in veterinary curricula and their assessment is often sporadic or inconsistent. In contrast, the same or similar competencies are being increasingly recognized in other health professions as essential skills and abilities, and their assessment is being undertaken with enhanced scrutiny and critical appraisal. Several challenges have been associated with the assessment of professional competencies, including agreement as to their definition and therefore their evaluation, the fact that they are frequently complex and require multiple integrative assessments, and the ability and/or desire of faculty to teach and assess these competencies. To provide an improved context for assessment of the seven professional competencies identified in the NAVMEC report, this article describes a broad framework for their evaluation as well as specific examples of how these or similar competencies are currently being measured in medical and veterinary curricula.

RESUMO

Although screening, brief intervention, and referral to treatment (SBIRT) has been a popular model to address potential substance abuse issues in primary care, there is a need for innovative approaches for training providers and staff on SBIRT protocols. An interdisciplinary approach to SBIRT training, named ICARE, was implemented at 3 different medical settings. The ICARE team trained 85 employees at an academic family medicine residency center and 37 employees across 2 rural community health care clinics. Using an innovative "learner-driven" approach, the authors implemented a combination of didactic and interactive training strategies that included on-site coaching, patient simulation exercises, as well as large- and small-group learning.

RESUMO

Integrated behavioral health care (IBHC) continues to grow as an evidence-based service delivery model adopted by healthcare systems all over the world to better care for the holistic needs of patients and their families. Medical family therapy (MedFT), as a field, has offered innovation to IBHC models by delivering biopsychosocial-spiritual (BPS-S), relational, and family-oriented care across a variety of healthcare contexts. This article details a longitudinal review of a program, spanning 16 years, that grew from no behavioral health services to one that is highly integrated, and embeds MedFTs in a number of rural community health centers. This model highlights the importance of interdisciplinary teams, including Peek's clinical, operational, financial, and training worlds, as well as decision-making metrics for systems that predominately care for underserved and minoritized populations. The authors illustrate a framework for how the levels of primary care/behavioral healthcare collaboration relate to the work and practice of MedFTs as conceptualized through the MedFT Health Care Continuum and meet the BPS-S needs of diverse populations seeking pediatric, adult, and dental healthcare services. Also described are shifts made in the model over time based on (a) growth in cultural humility, (b) relationally-oriented practice, operations, finance, and training data, and (c) research informed decisions. Recommendations include ways MedFTs can facilitate provider and administrative buy-in, assess model fidelity, and strive for quality outcomes for patients.

RESUMO

Cognitive impairment (e.g. dementia) presents challenges for individuals, their families, and healthcare professionals alike. The primary care setting presents a unique opportunity to care for older adults living with cognitive impairment, who present with complex care needs that may benefit from a family-centered approach. This indepth systematic review was completed to address three aims: (a) identify the ways in which families of older-adult patients with cognitive impairment are engaged in primary care settings, (b) examine the outcomes of family engagement practices, and (c) organize and discuss the findings using CJ Peek's Three World View. Researchers searched PubMed, Embase, and PsycINFO databases through July 2019. The results included 22 articles out of 6743 identified in the initial search. Researchers provided a description of the emerging themes for each of the three aims. It revealed that family-centered care and family engagement yields promising results including improved health outcomes, quality care, patient experience, and caregiver satisfaction. Furthermore, it promotes and advances the core values of medical family therapy: agency and communion. This review also exposed the inconsistent application of family-centered practices and the need for improved interprofessional education of primary care providers to prepare multidisciplinary teams to deliver family-centered care. Utilizing the vision of Patient- and Family-Centered Care and the lens of the Three World View, this systematic review provides Medical Family Therapists, healthcare administrators, policy makers, educators, and clinicians with information related to family engagement and how it can be implemented and enhanced in the care of patients with cognitive impairment.

RESUMO

INTRODUCTION: Integrated behavioral health care is an important pathway to providing whole person care. It is delivered through a transdisciplinary lens and team and funded through complex policies, billing codes, and systems. While the clinical practice of integrated behavioral health care has received attention in the research, less is known about how health care systems demonstrate and evaluate the utility, effectiveness, impact, and longevity of integrating behavioral health into primary care. METHOD: Health care professionals (N = 145) working in integrated settings were recruited to participate in a metaevaluation about their evaluation practices. Descriptive and regression analyses were used to summarize and evaluate findings on clinical, operational, and financial evaluation practices. RESULTS: There were a variety of types of evaluation practices across the national sample, as well as understanding across professional roles. Findings from the survey, which included primary care providers, behavioral health clinicians, and administrators working in integrated care settings confirmed that there was a lack of knowledge about evaluation and resources necessary to engage in the evaluation of clinical, operational, and financial outcomes. Furthermore, administrators were more likely to know about evaluation practices compared to medical providers and behavioral health providers. The survey also highlighted that organizational barriers to implementing integrated care were an issue across programs. DISCUSSION: Utilizing clinical, operational, and financial evaluation together provide a more comprehensive review of the implementation integrated behavioral health. Real-world implementers and evaluators should consider forming integrated and inclusive evaluation teams, including administrators, medical providers, behavioral health clinicians, patients, and families.

RESUMO

The earliest publications in the field of marriage and family therapy introduced interventions conducted with families experiencing complex health conditions. This strategic review captures an evaluation of efficacy for 87 couple and family interventions published between 2010 and 2019 with a focus on the leading causes of mortality in the United States. These health conditions include chromosomal anomalies and accidents with infants aged 0-4 years; accidents and cancer among children aged 5-14; accidents among adolescents aged 15-24; and heart disease, cancer, accidents, chronic lower respiratory diseases, stroke, Alzheimer's disease, diabetes, influenza/pneumonia, and nephritis/nephrosis among adults 25 and older. Results support the need for greater inclusion of couples and families in assessments and interventions. The greatest chasm in efficacy research was with minoritized couples and families. Implications include ways to initiate couple and family interventions in the context of health conditions with attention given to accessibility, recruitment, retention, and evaluation.

RESUMO

The mechanism of reductive cleavage of model alkyl halides (methyl 2-bromoisobutyrate, methyl 2-bromopropionate, and 1-bromo-1-chloroethane), used as initiators in living radical polymerization (LRP), has been investigated in acetonitrile using both experimental and computational methods. Both theoretical and experimental investigations have revealed that dissociative electron transfer to these alkyl halides proceeds exclusively via a concerted rather than stepwise manner. The reductive cleavage of all three alkyl halides requires a substantial activation barrier stemming mainly from the breaking C-X bond. The activation step during single electron transfer LRP (SET-LRP) was originally proposed to proceed via formation and decomposition of RX(•-) through an outer sphere electron transfer (OSET) process (Guliashvili, T.; Percec, V. J. Polym. Sci., Part A: Polym. Chem. 2007, 45, 1607). These radical anion intermediates were proposed to decompose via heterolytic rather than homolytic C-X bond dissociation. Here it is presented that injection of one electron into RX produces only a weakly associated charge-induced donor-acceptor type radical anion complex without any significant covalent σ type bond character between carbon-centered radical and associated anion leaving group. Therefore, neither homolytic nor heterolytic bond dissociation applies to the reductive cleavage of C-X in these alkyl halides inasmuch as a true radical anion does not form in the process. In addition, the whole mechanism of SET-LRP has to be revisited since it is based on presumed OSET involving intermediate RX(•-), which is shown here to be nonexistent.

RESUMO

The basic scheme for autooxidation of polymers, originally developed by Bolland, Gee and co-workers for rubbers and lipids, is now widely applied to all types of polymeric materials. According to their scheme, the reaction that makes this process autocatalytic, referred to as the propagation step, is a hydrogen abstraction from the next substrate by the peroxyl radical (ROO˙ + RH → ROOH + R˙). In this study, using advanced quantum-chemical methods, we have shown that this step is actually characterised by largely positive Gibbs free energy (10-65 kJ mol(-1)) for most regular polymers with saturated chains (polypropylene, polyethylene, polyvinyl chloride, polyvinyl acetate, polyurethane, poly(methyl methacrylate) etc.) and even some polymers with unsaturated fragments (polystyrene, polyethylene terephthalate). Neither elevated temperature, nor solvation makes this process thermodynamically favourable. Only when the formed radical centre is conjugated with adjacent double bonds (as in polybutadiene) or captodatively stabilised by two suitable functional groups (such as a carbonyl and a lone pair donor such as oxygen or nitrogen), is the propagation step exoergic. Instead, we show that it is the presence of structural defects, such as terminal or internal double bonds, formed either during polymerisation or in the degradation process itself, that is responsible for the autooxidation of most polyesters and most polyalkenes. Recognition of the real mechanism of autooxidation in polymers is a key to developing strategies for the prevention of their degradation.

RESUMO

In recent years, veterinary education has begun the transition to competency-based models, recognizing that, like medical education, our goals include improved patient and client outcomes and the importance of learner-centered methods in education. Given that implementation of competency-based veterinary education (CBVE) is still in its relative infancy across many veterinary programs, we stand to gain from a unified approach to its implementation. As a guideline, the five core components of competency-based medical education (CBME) should serve to ensure and maintain fidelity of the original design of outcomes-based education during implementation of CBVE. Identified the essential and indispensable elements of CBME which include 1) clearly articulated outcome competencies required for practice, 2) sequenced progression of competencies and their developmental markers, 3) tailored learning experiences that facilitate the acquisition of competencies, 4) competency-focused instruction that promotes the acquisition of competencies, and 5) programmatic assessment. This review advocates the adoption of the principles contained in the five core components of CBME, outlines the approach to implementation of CBVE based upon the five core components, and addresses the key differences between veterinary and medical education which may serve as challenges to ensuring fidelity of CBVE during implementation.

RESUMO

BACKGROUND: Musculoskeletal traumas are on the rise in the United States; however, limited studies are available to help trauma providers assess and treat concerns beyond the physical impact. Little is understood about the psychological, social, and spiritual factors that protect patients from adverse effects after a physical trauma or their experiences with each factor afterward. OBJECTIVE: This systematic review was conducted to investigate and review advancements in research related to risk and resiliency factors experienced by survivors of traumatic musculoskeletal injuries. The use of biopsychosocial-spiritual (BPS-S) framework and resiliency theory guided the analysis. METHODS: Researchers reviewed 1003 articles, but only seven met the search criteria. Due to the complexity and uniqueness of traumatic brain injuries, studies on that target population were excluded. RESULTS: Of the seven articles reviewed, three identified psychological protective factors that protect against negative health outcomes; three identified negative psychological, social, or spiritual outcomes; and none investigated social or spiritual health. CONCLUSIONS: There are significant gaps in the literature surrounding risk and resiliency factors related to the BPS-S health of musculoskeletal injury survivors.

RESUMO

Free energies for the homolysis of the NO-C and N-OC bonds were compared for a large number of alkoxyamines at 298 and 393 K, both in the gas phase and in toluene solution. On this basis, the scope of the N-OC homolysis side reaction in nitroxide-mediated polymerization was determined. It was found that the free energies of NO-C and N-OC homolysis are not correlated, with NO-C homolysis being more dependent upon the properties of the alkyl fragment and N-OC homolysis being more dependent upon the structure of the aminyl fragment. Acyclic alkoxyamines and those bearing the indoline functionality have lower free energies of N-OC homolysis than other cyclic alkoxyamines, with the five-membered pyrrolidine and isoindoline derivatives showing lower free energies than the six-membered piperidine derivatives. For most nitroxides, N-OC homolysis is normally favored above NO-C homolysis only when a heteroatom that is α to the NOC carbon center stabilizes the NO-C bond and/or the released alkyl radical is not sufficiently stabilized. As part of this work, accurate methods for the calculation of free energies for the homolysis of alkoxyamines were determined. Accurate thermodynamic parameters to within 4.5 kJ mol(-1) of experimental values were found using an ONIOM approximation to G3(MP2)-RAD combined with PCM solvation energies at the B3-LYP/6-31G(d) level.

RESUMO

Introduction: Primary care agencies remain an ideal setting for implementing parenting programs that meet the needs of Latinx parents. However, little to no research has been done on how well adapted primary care parenting programs (PCPPs) are to the beliefs, values, and practices of many Latinx families. Method: Using 5 inclusion criteria, 8 PCPPs were selected and compared across 8 domains: focus, age of child, composition, sequence, duration, training length, estimated start-up costs, and number of cultural adaptations. Results: PCPPs vary widely across all 8 domains, with some PCPPs being relatively brief and low cost and others more all encompassing and expensive. Only 4 of the 8 programs demonstrated cultural adaptations outside Spanish translation. Conclusion: This comparison demonstrates that there is a lack of cultural consideration among researchers who develop PCPPs. Recommendations for providing culturally attuned parenting services for Latinx families within a primary care environment are given. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

RESUMO

A test set of 21 radical addition and 28 hydrogen abstraction reactions has been studied at the W1, G4, G3X, G3X(MP2), and G3X(MP2)-RAD levels of theory with a view to establishing whether the recently introduced G4 theory offers improved performance over the G3 methods. All methods tested approximated the benchmark W1 values to within a mean absolute deviation (MAD) of 4 kJ mol(-1) or less, although maximum absolute deviations for problematic reactions (such as radical addition to thiocarbonyl compounds) can be as much as 10 kJ mol(-1) for the G3 methods. The new noncanceling higher-level correction (HLC) term in G4 was found to be capable of mitigating these errors in radical addition, but it introduced a systematic error to the reaction energies of the abstraction reactions, and its format may therefore require re-examination. G3 methods were shown to offer "chemical accuracy" even for these problematic cases, provided they were corrected to the W1 level of theory via an ONIOM-based approach.
