The feasibility and acceptability of using virtual world technology for interprofessional education in palliative care: a mixed methods study.

The objective of this mixed methods study was to evaluate the feasibility and acceptability of using a virtual world educational environment for interprofessional health professions students learning about palliative care. Graduate students (n = 35) from five different health professions programs (medicine, nursing, nutrition, physical therapy, and social work) across two educational institutions participated in a small-group immersive educational experience focused on palliative care in the virtual world of Second Life. Collected data included pre and post surveys of interprofessional attitudes using previously-published questionnaires as well as student reflective writing and photographs about their experience. We found it was feasible to create and deliver an interprofessional educational experience in palliative care in a virtual world environment. The educational experience was acceptable to participants, with an improvement in attitudes toward interprofessional education and interprofessional teamwork after a single virtual world educational session, based on both quantitative and qualitative results. Students found the virtual world environment acceptable for interprofessional education focused on palliative care, based on qualitative results. As health professions schools develop interprofessional education curricula, the use of virtual world technology may be an important modality to consider, to effectively and conveniently bring interprofessional learners together.

Revealing the Hidden Clerkship Curriculum: A Qualitative Analysis.

BACKGROUND AND OBJECTIVES: Family medicine (FM) clerkships have learning objectives to define what students should learn by the end of their clerkship, but how do we know what larger lessons students are taking away? This study aimed to explore the FM clerkship explicit and hidden curriculum. METHODS: Students were asked to list their top five take-home points at the end of their FM clerkship at two institutions. A total of 668 written reflections were qualitatively analyzed. RESULTS: Thirteen code categories emerged: scope of practice, health care systems, role of FM in the system, traits of a family doctor, values of FM, cultural competency and social justice, challenges of FM care, evidence-based medicine, clinical skills for a student, personal impact, life skills and tips, patient centeredness, and clinical pearls. Prominent subcategories included prevention, team-based care, doctor-patient relationship, and continuity of care. CONCLUSIONS: When compared to the FM clerkship learning objectives at both institutions, four code categories emerged that were not part of the explicit objectives: traits of a family doctor, challenges in FM care, personal impact, and life skills and tips. Conversely, some nuances of the learning objective of FM in the health care system regarding decreasing cost and improving health outcomes and equity were not represented in the coded categories of student responses. These findings could potentially help FM clerkships nationally define ways to improve messaging around challenges in FM care and help the 25 x 2030 initiative to produce more family physicians in the United States.

The Relationship Between Medical School Clerkships and Primary Care Specialty Choice: A Narrative Review.

BACKGROUND AND OBJECTIVES: There is a persistent shortage of primary care physicians in the United States. Medical schools can help meet societal primary care health needs by graduating more students who select family medicine and other primary care careers. The objective of this narrative review was to evaluate the relationship between clerkships and primary care specialty choice. METHODS: We conducted a systematic literature search and narrative review of research articles examining the association between clerkships and primary care specialty choice. We evaluated the quality of included articles using a validated scale, assessed for methodology and outcomes, and synthesized using a narrative approach. RESULTS: We identified 59 articles meeting our research criteria. A required primary care clerkship in the core clerkship year was associated with increased primary care specialty choice. This finding was strongest for family medicine clerkships and family medicine specialty choice. Clerkships that were longer, were of higher quality, exposed students to a wider scope of primary care practice, and occurred within an institutional climate supportive of primary care were also correlated with more students choosing a primary care specialty. While student self-reported interest in primary care often increased following a primary care clerkship, this interest was not always sustained or consistently associated with a primary care residency match or primary care career. CONCLUSIONS: Required family medicine and primary care clerkships were correlated with primary care specialty choice. More high-quality research is needed to better understand how to maximize the impact of clerkships on primary care specialty choice.

Medical School Characteristics, Policies, and Practices That Support Primary Care Specialty Choice: A Scoping Review of 5 Decades of Research.

BACKGROUND AND OBJECTIVES: The United States, like many other nations, faces a chronic shortage of primary care physicians. The purpose of this scoping review was to synthesize literature describing evidence-based institutional practices and interventions that support medical students' choices of primary care specialties, published in the United States, Canada, Australia, and New Zealand. METHODS: We surveyed peer-reviewed, published research. An experienced medical librarian conducted searches of multiple databases. Articles were selected for inclusion based on explicit criteria. We charted articles by topic, methodology, year of publication, journal, country of origin, and presence or absence of funding. We then scored included articles for quality. Finally, we defined and described six common stages of development of institutional interventions. RESULTS: We reviewed 8,083 articles and identified 199 articles meeting inclusion criteria and 41 related articles. As a group, studies were of low quality, but improved over time. Most were quantitative studies conducted in the United States. Many studies utilized one of four common methodologic approaches: retrospective surveys, studies of programs or curricula, large-scale multi-institution comparisons, and single-institution exemplars. Most studies developed groundwork or examined effectiveness or impact, with few studies of planning or piloting. Few studies examined state or regional workforce outcomes. CONCLUSIONS: Research examining medical school interventions and institutional practices to support primary care specialty choice would benefit from stronger theoretical grounding, greater investment in planning and piloting, consistent use of language, more qualitative methods, and innovative approaches. Robust funding mechanisms are needed to advance these goals.

Alpha Omega Alpha Honor Medical Society: A Commitment to Inclusion, Diversity, Equity, and Service in the Profession of Medicine.

With a motto of "Be Worthy to Serve the Suffering," Alpha Omega Alpha Honor Medical Society (AΩA) supports the importance, inclusion, and development of a culturally and ethnically diverse medical profession with equitable access for all. The underrepresentation of minorities in medical schools and medicine continues to be a challenge for the medical profession, medical education, and AΩA. AΩA has worked, and continues to work, to ensure the development of diverse leaders, fostering within them the objectivity and equity to be inclusive servant leaders who understand and embrace diversity in all its forms.Inclusion of talented individuals from different backgrounds benefits patient care, population health, education, and scientific discovery. AΩA values an inclusive, diverse, fair, and equitable work and learning environment for all and supports the medical profession in its work to achieve a welcoming, inclusive environment in teaching, learning, caring for patients, and collaboration.The diversity of medical schools is changing and will continue to change. AΩA is committed to continuing to work with its members, medical school deans, and AΩA chapters to assure that AΩA elections are unbiased and based on the values of AΩA and the profession of medicine in service to patients and the profession.Progress toward diversity, inclusion, and equity is more than simply checking off a box or responding to criticism-it is about being and developing diverse excellent physicians. AΩA and all those in the medical profession must continue to guide medicine to be unbiased, open, accepting, inclusive, and culturally aware in order to "Be Worthy to Serve the Suffering."

Predicted loss and gain of function mutations in ACO1 are associated with erythropoiesis.

Hemoglobin is the essential oxygen-carrying molecule in humans and is regulated by cellular iron and oxygen sensing mechanisms. To search for novel variants associated with hemoglobin concentration, we performed genome-wide association studies of hemoglobin concentration using a combined set of 684,122 individuals from Iceland and the UK. Notably, we found seven novel variants, six rare coding and one common, at the ACO1 locus associating with either decreased or increased hemoglobin concentration. Of these variants, the missense Cys506Ser and the stop-gained Lys334Ter mutations are specific to eight and ten generation pedigrees, respectively, and have the two largest effects in the study (EffectCys506Ser = -1.61 SD, CI95 = [-1.98, -1.35]; EffectLys334Ter = 0.63 SD, CI95 = [0.36, 0.91]). We also find Cys506Ser to associate with increased risk of persistent anemia (OR = 17.1, P = 2 × 10-14). The strong bidirectional effects seen in this study implicate ACO1, a known iron sensing molecule, as a major homeostatic regulator of hemoglobin concentration.

MAP1B mutations cause intellectual disability and extensive white matter deficit.

Discovery of coding variants in genes that confer risk of neurodevelopmental disorders is an important step towards understanding the pathophysiology of these disorders. Whole-genome sequencing of 31,463 Icelanders uncovers a frameshift variant (E712KfsTer10) in microtubule-associated protein 1B (MAP1B) that associates with ID/low IQ in a large pedigree (genome-wide corrected P = 0.022). Additional stop-gain variants in MAP1B (E1032Ter and R1664Ter) validate the association with ID and IQ. Carriers have 24% less white matter (WM) volume (ß = -2.1SD, P = 5.1 × 10-8), 47% less corpus callosum (CC) volume (ß = -2.4SD, P = 5.5 × 10-10) and lower brain-wide fractional anisotropy (P = 6.7 × 10-4). In summary, we show that loss of MAP1B function affects general cognitive ability through a profound, brain-wide WM deficit with likely disordered or compromised axons.

A truncating mutation in EPOR leads to hypo-responsiveness to erythropoietin with normal haemoglobin.

The cytokine erythropoietin (EPO), signalling through the EPO receptor (EPO-R), is essential for the formation of red blood cells. We performed a genome-wide association study (GWAS) testing 32.5 million sequence variants for association with serum EPO levels in a set of 4187 individuals. We detect an association between a rare and well imputed stop-gained variant rs370865377[A] (p.Gln82Ter) in EPOR, carried by 1 in 550 Icelanders, and increased serum EPO levels (MAF = 0.09%, Effect = 1.47 SD, P = 3.3 × 10-7). We validated these findings by measuring serum EPO levels in 34 additional pairs of carriers and matched controls and found carriers to have 3.23-fold higher EPO levels than controls (P = 1.7 × 10-6; P combined = 1.6 × 10-11). In contrast to previously reported EPOR mutations, p.Gln82Ter does not associate with haemoglobin levels (Effect = -0.045 SD, P = 0.32, N = 273,160), probably due to a compensatory EPO upregulation in response to EPO-R hypo-responsiveness.

What should physicians know about hypertension? The implicit knowledge requirements in the maintenance of certification self-assessment module.

BACKGROUND AND OBJECTIVES: The American Board of Family Medicine (ABFM) Maintenance of Certification process requires family physicians to have a core knowledge base in key areas such as hypertension and diabetes care but does not define this knowledge in specific terms. We developed a method of content analysis to evaluate what type of knowledge is assessed on the ABFM's Hypertension Self-assessment Module (SAM) to better understand what the implied knowledge of a family physician should be. METHODS: In this qualitative descriptive analysis, we categorized the 60 questions comprising the knowledge assessment portion of the Hypertension SAM, version 2.20.03, into diagnosis, treatment, or etiology/general knowledge questions. Diagnosis and treatment questions were graded for relevance to typical family practice. Diagnosis questions were coded regarding importance. Treatment questions were subdivided into drug or nondrug treatments. Drug treatment items were categorized as testing knowledge of safety/tolerability issues, effectiveness issues, or cost considerations. RESULTS: The 60 questions represented 213 specific items of knowledge. Most (71%) of the items on the SAM focused on therapy, with the remainder evaluating knowledge of diagnosis issues or general knowledge. Of the therapy-related items, the items were evenly split between knowledge of safety/tolerability and knowledge of effectiveness (47.1% each). The remaining items required knowledge of nondrug therapy. No items evaluated knowledge of the relative cost of treatment or cost-effectiveness. With regard to the relevance of the tested information, only 70% of the items test knowledge that would be commonly needed in the practice of family medicine. CONCLUSIONS: There is currently no consensus on the discrete set of skills and knowledge that should be held by a competent family physician. In the absence of a comprehensive set of goals and objectives, the knowledge content being assessed in the SAMs can at least inform teaching programs about what their learners will be required to know to maintain certification. For the content area of hypertension, most of the knowledge required was regarding drug treatment. Interestingly, 30% of the knowledge content being assessed was found to be neither important nor commonly needed in the care of patients. We recommend that more work be done to define the specific knowledge and skills required for a competent family physician and that future maintenance of certification modules be written to assess mastery of these core requirements.

A new Caenorhabditis elegans model of human huntingtin 513 aggregation and toxicity in body wall muscles.

Expanded polyglutamine repeats in different proteins are the known determinants of at least nine progressive neurodegenerative disorders whose symptoms include cognitive and motor impairment that worsen as patients age. One such disorder is Huntington's Disease (HD) that is caused by a polyglutamine expansion in the human huntingtin protein (htt). The polyglutamine expansion destabilizes htt leading to protein misfolding, which in turn triggers neurodegeneration and the disruption of energy metabolism in muscle cells. However, the molecular mechanisms that underlie htt proteotoxicity have been somewhat elusive, and the muscle phenotypes have not been well studied. To generate tools to elucidate the basis for muscle dysfunction, we engineered Caenorhabditis elegans to express a disease-associated 513 amino acid fragment of human htt in body wall muscle cells. We show that this htt fragment aggregates in C. elegans in a polyglutamine length-dependent manner and is toxic. Toxicity manifests as motor impairment and a shortened lifespan. Compared to previous models, the data suggest that the protein context in which a polyglutamine tract is embedded alters aggregation propensity and toxicity, likely by affecting interactions with the muscle cell environment.

Teaching cross-cultural communication skills online: a multi-method evaluation.

BACKGROUND AND OBJECTIVES: Cultural competency education is an important and required part of undergraduate medical education. The objective of this study was to evaluate whether an online cross-cultural communication module could increase student use of cross-cultural communication questions that assess the patient's definition of the problem, the way the problem affects their life, their concerns about the problem, and what the treatment should be (PACT). METHODS: We used multi-method assessment of students assigned to family medicine clerkship blocks that were randomized to receive online cultural competency and PACT training added to their standard curriculum or to a control group receiving the standard curriculum only. Outcomes included comparison, via analysis of variance, of number of PACT questions used during an observed Standardized Patient Exercise, end-of-year OSCE scores, and qualitative analysis of student narratives. RESULTS: Students (n=119) who participated in the online module (n=60) demonstrated increased use of cross-cultural communication PACT questions compared to the control group (n=59) and generally had positive themes emerge from their reflective writing. The module had the biggest impact on students who later went on to match in high communication specialties. CONCLUSIONS: Online teaching of cross-cultural communication skills can be effective at changing medical student behavior.

Therapeutic exercise attenuates neutrophilic lung injury and skeletal muscle wasting.

Early mobilization of critically ill patients with the acute respiratory distress syndrome (ARDS) has emerged as a therapeutic strategy that improves patient outcomes, such as the duration of mechanical ventilation and muscle strength. Despite the apparent efficacy of early mobility programs, their use in clinical practice is limited outside of specialized centers and clinical trials. To evaluate the mechanisms underlying mobility therapy, we exercised acute lung injury (ALI) mice for 2 days after the instillation of lipopolysaccharides into their lungs. We found that a short duration of moderate intensity exercise in ALI mice attenuated muscle ring finger 1 (MuRF1)-mediated atrophy of the limb and respiratory muscles and improved limb muscle force generation. Exercise also limited the influx of neutrophils into the alveolar space through modulation of a coordinated systemic neutrophil chemokine response. Granulocyte colony-stimulating factor (G-CSF) concentrations were systemically reduced by exercise in ALI mice, and in vivo blockade of the G-CSF receptor recapitulated the lung exercise phenotype in ALI mice. Additionally, plasma G-CSF concentrations in humans with acute respiratory failure (ARF) undergoing early mobility therapy showed greater decrements over time compared to control ARF patients. Together, these data provide a mechanism whereby early mobility therapy attenuates muscle wasting and limits ongoing alveolar neutrophilia through modulation of systemic neutrophil chemokines in lung-injured mice and humans.

Novel polyglutamine model uncouples proteotoxicity from aging.

Polyglutamine expansions in certain proteins are the genetic determinants for nine distinct progressive neurodegenerative disorders and resultant age-related dementia. In these cases, neurodegeneration is due to the aggregation propensity and resultant toxic properties of the polyglutamine-containing proteins. We are interested in elucidating the underlying mechanisms of toxicity of the protein ataxin-3, in which a polyglutamine expansion is the genetic determinant for Machado-Joseph Disease (MJD), also referred to as spinocerebellar ataxia 3 (SCA3). To this end, we have developed a novel model for ataxin-3 protein aggregation, by expressing a disease-related polyglutamine-containing fragment of ataxin-3 in the genetically tractable body wall muscle cells of the model system C. elegans. Here, we demonstrate that this ataxin-3 fragment aggregates in a polyQ length-dependent manner in C. elegans muscle cells and that this aggregation is associated with cellular dysfunction. However, surprisingly, this aggregation and resultant toxicity was not influenced by aging. This is in contrast to polyglutamine peptides alone whose aggregation/toxicity is highly dependent on age. Thus, the data presented here not only describe a new polyglutamine model, but also suggest that protein context likely influences the cellular interactions of the polyglutamine-containing protein and thereby modulates its toxic properties.
