RESUMO

BACKGROUND: The benefits of friendships among peers with and without intellectual and developmental disabilities are well supported by research. However, little is known about the nature of these inclusive friendships in inclusive college courses. METHOD: We explored the perspectives of peers on the development of authentic friendships among peers with and without intellectual and developmental disabilities in inclusive college courses in the United States. We used a sequential, explanatory, transformative mixed methods-grounded theory research design. We integrated quantitative (N = 44) and qualitative (N = 8) findings using blended analysis to inform a preliminary grounded theory of inclusive and reciprocal friendships. RESULTS: Quantitative findings suggest two relationships and one predictor of peers' perceived social engagement. Qualitative findings resulted in five themes that promote friendships. CONCLUSIONS: We propose that the context for developing inclusive friendships could be fostered using the preparation and actions stages of the grounded theory model.

RESUMO

A hallmark of macroautophagy is the covalent lipidation of LC3 and insertion into the double-membrane phagophore, which is driven by the ATG16L1/ATG5-ATG12 complex. In contrast, non-canonical autophagy is a pathway through which LC3 is lipidated and inserted into single membranes, particularly endolysosomal vacuoles during cell engulfment events such as LC3-associated phagocytosis. Factors controlling the targeting of ATG16L1 to phagophores are dispensable for non-canonical autophagy, for which the mechanism of ATG16L1 recruitment is unknown. Here we show that the WD repeat-containing C-terminal domain (WD40 CTD) of ATG16L1 is essential for LC3 recruitment to endolysosomal membranes during non-canonical autophagy, but dispensable for canonical autophagy. Using this strategy to inhibit non-canonical autophagy specifically, we show a reduction of MHC class II antigen presentation in dendritic cells from mice lacking the WD40 CTD Further, we demonstrate activation of non-canonical autophagy dependent on the WD40 CTD during influenza A virus infection. This suggests dependence on WD40 CTD distinguishes between macroautophagy and non-canonical use of autophagy machinery.

RESUMO

Many are calling for concrete mechanisms of oversight for health research involving artificial intelligence (AI). In response, institutional review boards (IRBs) are being turned to as a familiar model of governance. Here, we examine the IRB model as a form of ethics oversight for health research that uses AI. We consider the model's origins, analyze the challenges IRBs are facing in the contexts of both industry and academia, and offer concrete recommendations for how these committees might be adapted in order to provide an effective mechanism of oversight for health-related AI research.

RESUMO

Adaptive changes in lysosomal capacity are driven by the transcription factors TFEB and TFE3 in response to increased autophagic flux and endolysosomal stress, yet the molecular details of their activation are unclear. LC3 and GABARAP members of the ATG8 protein family are required for selective autophagy and sensing perturbation within the endolysosomal system. Here, we show that during the conjugation of ATG8 to single membranes (CASM), Parkin-dependent mitophagy, and Salmonella-induced xenophagy, the membrane conjugation of GABARAP, but not LC3, is required for activation of TFEB/TFE3 to control lysosomal capacity. GABARAP directly binds to a previously unidentified LC3-interacting motif (LIR) in the FLCN/FNIP tumor suppressor complex and mediates sequestration to GABARAP-conjugated membrane compartments. This disrupts FLCN/FNIP GAP function toward RagC/D, resulting in impaired substrate-specific mTOR-dependent phosphorylation of TFEB. Thus, the GABARAP-FLCN/FNIP-TFEB axis serves as a molecular sensor that coordinates lysosomal homeostasis with perturbations and cargo flux within the autophagy-lysosomal network.

RESUMO

Monitoring of ATG8 proteins by western blotting and immunofluorescence microscopy are the most common methods to monitor the autophagy pathway. However, it has recently been shown that ATG8 proteins can be lipidated to non-autophagosome, single-membrane compartments through a noncanonical autophagy pathway. This is commonly found to occur during macro-endocytic processes such as phagocytosis, where it has been termed LC3-associated phagocytosis, and upon lysosomotropic drug treatment. Therefore, care is required when interpreting data based on ATG8 in order to conclude whether a signal relates to the canonical or noncanonical pathway. Here we provide methods to monitor noncanonical autophagy through fluorescence microscopy.

RESUMO

BACKGROUND: Concept-based curricula, coupled with conceptual approach to teaching, fosters conceptual learning. There is a need for clarity in the definition of conceptual learning. METHOD: Walker and Avant's method of concept analysis was used. RESULTS: Conceptual learning is a process in which learners organize concept-relevant knowledge, skills, and attitudes to form logical cognitive connections resulting in assimilation, storage, retrieval, and transfer of concepts to applicable situations, familiar and unfamiliar. Attributes identified were (a) recognizing patterns in information, (b) forming linkages with concepts, (c) acquiring deeper understanding of concepts, (d) developing personal relevance, and (e) applying concepts to other situations. Antecedents were (a) learner cognitive potential, (b) organized conceptual framework, and (c) conceptual approach to teaching. Consequences were (a) enhanced synthesis and analysis, (b) improved problem solving, (c) ability to translate theory to practice, (d) appreciation of linear/nonlinear ways of thinking, and (e) enhanced concept construction. CONCLUSION: This analysis provides a referent for recognizing the occurrence of conceptual learning and developing instruments to measure its outcomes. [J Nurs Educ. 2019;58(1):7-15.].

RESUMO

Health care employers demand that workers be skilled in clinical reasoning, able to work within complex interprofessional teams to provide safe, quality patient-centered care in a complex evolving system. To this end, there have been calls for radical transformation of nursing education including the development of a baccalaureate generalist nurse. Based on recommendations from the American Association of Colleges of Nursing, faculty concluded that clinical education must change moving beyond direct patient care by applying the concepts associated with designer, manager, and coordinator of care and being a member of a profession. To accomplish this, the faculty utilized a system of focused learning assignments (FLAs) that present transformative learning opportunities that expose students to "disorienting dilemmas," alternative perspectives, and repeated opportunities to reflect and challenge their own beliefs. The FLAs collected in a "Playbook" were scaffolded to build the student's competencies over the course of the clinical experience. The FLAs were centered on the 6 Quality and Safety Education for Nurses competencies, with 2 additional concepts of professionalism and systems-based practice. The FLAs were competency-based exercises that students performed when not assigned to direct patient care or had free clinical time. Each FLA had a lesson plan that allowed the student and faculty member to see the competency addressed by the lesson, resources, time on task, student instructions, guide for reflection, grading rubric, and recommendations for clinical instructor. The major advantages of the model included (a) consistent implementation of structured learning experiences by a diverse teaching staff using a coaching model of instruction; (b) more systematic approach to present learning activities that build upon each other; (c) increased time for faculty to interact with students providing direct patient care; (d) guaranteed capture of selected transformative learning experiences; (e) increased student reflection to promote transformative learning; and (f) provided avenues for timely feedback to students.

RESUMO

Undergraduate curriculum revision is a daunting task, particularly when new accreditation criteria clearly call for substantive changes in how baccalaureate generalist nurses are educated. Using the nine essentials of The Essentials of Baccalaureate Education for Professional Nursing Practice (American Association of Colleges of Nursing, 2008) and the 109 Essential outcomes, the University of Kansas School of Nursing undergraduate faculty employed three phases of change: (a) understanding, (b) analysis, and (c) design to create an innovative curriculum. Theoretical influences from E. M. Rogers' (2003) Diffusion of Innovations theory, W. Bridges' (2009) work with transitions, and concepts of ownership guided the revision process. Strategies, such as gap analysis, nominal group technique, and word clouds, facilitated faculty transition from the ending of the old curriculum to ownership and beginning of the new curriculum. Inductive methods of faculty perceptions of ideal graduate characteristics and clustering of themes in the 109 Essential outcomes produced five themes: (a) communication/professional development, (b) evidence-based practice, (c) leadership/management, (d) nursing across the lifespan, and (e) population-based health care. A Q-Sort of the Essentials placed all 109 essential outcomes under each of these categories. Essential outcomes within these categories were then interpreted as data points and used as the basis for course design and accompanying credit allocation. A variety of research, theory, and interpersonally sensitive approaches yielded an innovative curriculum reflecting the Essentials and "new beginnings" for the undergraduate faculty.

RESUMO

The virtual physiological human (VPH) initiative encompasses a wide range of activities, including structural and functional imaging, data mining, knowledge discovery tool and database development, biomedical modelling, simulation and visualization. The VPH community is developing from a multitude of relatively focused, but disparate, research endeavours into an integrated effort to bring together, develop and translate emerging technologies for application, from academia to industry and medicine. This process initially builds on the evolution of multi-disciplinary interactions and abilities, but addressing the challenges associated with the implementation of the VPH will require, in the very near future, a translation of quantitative changes into a new quality of highly trained multi-disciplinary personnel. Current strategies for undergraduate and on-the-job training may soon prove insufficient for this. The European Commission seventh framework VPH network of excellence is exploring this emerging need, and is developing a framework of novel training initiatives to address the predicted shortfall in suitably skilled VPH-aware professionals. This paper reports first steps in the implementation of a coherent VPH training portfolio.
