RESUMO
OBJECTIVES: Clinicians in the emergency department (ED) frequently encounter seriously ill patients at a time when advance directives may be pivotal in improved clinician decision-making. The objectives of this study were to identify the prevalence of advanced directives in ED patients, as well as patterns of advance care discussions between patients and providers. This study describes patients' perceptions and expectations of such serious illness discussions in an emergency care setting with the expectation of including patients as strategic members of the care team. METHODS: Trained research assistants in two emergency departments surveyed patients over age 65, or their caregivers, from July 2016 to August 2018. Patients were verbally administered a standard survey tool related to advance directives and advance care planning. RESULTS: 497 out of 877 patients completed surveys (59.4%). 50% of patients reported having an advance care planning document. The large majority (92%) of patients with an advance directive had not been asked about it during their ED visit. When questioned about their personal preferences, 79% of patients thought emergency physicians should be aware of their wishes regarding life-sustaining treatments and end-of-life care. Paradoxically, only 38% expressed a desire to discuss advance care plans with an ED clinician. CONCLUSIONS: Older patients expect emergency clinicians to be aware of their care preferences, yet most are not asked about these care preferences in the ED. The large gap between patient preference and reality suggests the need for more targeted discussion by ED clinicians and translation of patient perspectives into system healthcare improvements. Future studies should explore barriers to advance care planning in the ED as well as patient preferences for these conversations to support a true healthcare learning system.
RESUMO
BACKGROUND: Interprofessional education is recognized as an important part of the training of future health professionals. Limited investigation has been done on the experiences of students who have completed interprofessional mentored research during their clinical training. PURPOSE: To explore if this experience provided meaningful training in key areas of interprofessional education. METHOD: Using a qualitative descriptive framework, one-on-one interviews were conducted with eight healthcare providers (three occupational therapists and five speech language pathologists) who engaged in interprofessional research during their clinical training. Qualitative content analysis was completed with triangulation by analyst and member checking. CONCLUSION: Three main themes were identified: 1) interprofessional research project collaboration, 2) professional development, and 3) recommendations for student-oriented interprofessional research collaborations. The results illustrated that the health practitioners found their student experiences valuable to their current interprofessional practice and provided salient training on roles and responsibilities, teamwork, and communication.

BACKGROUND: Half of the 4.7 M veterans who reside in rural communities and rely on U.S. Department of Veterans Affairs (VA) health care are older (≥65). Their rurality presents unique challenges, including a shortage of clinicians skilled in geriatric medicine. Community-based outpatient clinics (CBOCs) help extend VA's geographic reach but are typically located in under-resourced settings. Telemedicine may increase access to care, but little is known about CBOCs' capacity to leverage telemedicine to meet older patients' needs. We identified organizational barriers and facilitators to the use of geriatric telemedicine specialty care from the perspective of rural clinicians and staff. METHODS: From February-April 2020, we interviewed CBOC clinicians and staff (N = 50) from 13 rural CBOCs affiliated with four VA Geriatric Research Education and Clinical Centers. Semi-structured interviews addressed patient population characteristics; CBOC location, staffing, and in-house resources; use of VA specialty care services; and telemedicine use. We developed a codebook using an iterative process and Gale's Framework Method thematically organize and analyze data. RESULTS: Respondents perceived that their CBOCs serve a predominantly older patient population. Four characteristics enabled CBOCs to offer geriatric telemedicine specialty care: partnerships with larger VA Medical Center teams; social worker/telehealth clinical technician knowledge of geriatrics and telehealth resources; periodic outreach/education from geriatric specialists; and routine use of other telehealth services. Barriers included: constraints on clinic space and unstable internet for telemedicine visits; staffing challenges leading to limited familiarity with telemedicine resources; and clinician and staff perceptions of older veterans' preference for in-person visits. CONCLUSIONS: Telemedicine is an important modality to enhance access to care for an increasingly older and medically complex patient population. Although rural CBOCs provide a large portion of care to VA's growing geriatric population, staff are insufficiently trained in geriatrics, work in resource-poor settings, and are largely unaware of VA telemedicine programs designed to support them.

Circadian Rhythm Sleep-Wake Disorders (CRSWDs) are important sleep disorders whose unifying feature is a mismatch between the preferred or required times for sleep and wakefulness and the endogenous circadian drives for these. Their etiology, presentation, and treatment can be different in pediatric patients as compared to adults. Evaluation of these disorders must be performed while viewed through the lens of a patient's comorbid conditions. Newer methods of assessment promise to provide greater diagnostic clarity and critical insights into how circadian physiology affects overall health and disease states. Effective clinical management of CRSWDs is multimodal, requiring an integrated approach across disciplines. Therapeutic success depends upon appropriately timed nonpharmacologic and pharmacologic interventions. A better understanding of the genetic predispositions for and causes of CRSWDs has led to novel clinical opportunities for diagnosis and improved therapeutics.

AIMS: To introduce a resource supporting research on Gulf War illness (GWI) and related disorders, the Gulf War Veterans' Illnesses Biorepository (GWVIB). METHODS: Gulf War era veterans (GWVs) are recruited nationally and enrolled via telephone and email/postal mail. Enrolled veterans receive annual telephone and mail follow-up to collect health data until their passing. A postmortem neuropathological examination is performed, and fixed and frozen brain and spinal cord samples are banked to support research. Investigators studying GWI and related disorders may request tissue and data from the GWVIB. RESULTS: As of September 2021, 127 GWVs from 39 states were enrolled; 60 met the criteria for GWI, and 14 met the criteria for chronic multisymptom illness (CMI). Enrollees have been followed up to six years. Postmortem tissue recoveries were performed on 14 GWVs. The most commonly found neuropathologies included amyotrophic lateral sclerosis, chronic traumatic encephalopathy, and Lewy body disease. Tissue was of good quality with an average RNA integrity number of 5.8 (SD = 1.0) and ≥4.8 in all of the cases. DISCUSSION: The availability of health data and high-quality CNS tissue from this well-characterized GWV cohort will support research on GWI and related disorders affecting GWVs. Enrollment is ongoing.
RESUMO
Perniosis, or chilblain, is characterized by skin lesions that occur as an abnormal reaction to exposure to cold and damp conditions. It can present as an idiopathic dermatosis or in association with an underlying connective tissue or autoimmune disease. Differentiation by histopathologic examination is controversial. Herein, we report a unique case of a 73-year-old woman who developed acquired perniosis on the buttocks from the use of ice packs to treat chronic low back pain.

Fibrofolliculoma and trichodiscoma are adnexal tumors that arise from or around hair follicles and are two of the many characteristic features of Birt-Hogg-Dubé (BHD) syndrome. Fibrofolliculoma and other hair follicle hamartomas can be differentiated from their clinically indistinct counterparts (eg, trichodiscomas, trichoadenomas) by histologic and staining comparison. We report a rare case of a 54-year-old man who presented with a subcutaneous papule on the abdomen that was histologically proven to have features of both a solitary fibrofolliculoma and trichodiscoma.

The evaluation of ecosystem quality is inherently subjective, requiring decisions about which variables to notice or measure, and how these variables are integrated into a coherent evaluation. Despite the central role of human judgment, few evaluation methods address the subjectivity that is inherent in their design. There are, however, advantages to directly using opinion to create an expert system where the metric is constructed around opinion data. These advantages include stakeholder inclusion and the encouragement of a dialogue of data-driven criticism rather than subjective counter-opinion. We create an expert system to express the quality of a grassland ecosystem in Australia. We use an ensemble of bagged regression trees trained on calibrated expert preference data, to model the perceived quality of this grassland using a set of eight site variables as inputs. The model provides useful predictions of grassland quality, producing predictions similar to real expert evaluations of independent synthetic test sites not used to train the model. We apply the model to real grassland sites ranging from pristine to highly degraded, and confirm that our model orders the sites according to their degree of modification. We demonstrate that the use of too few experts produces relatively poor results, and show that for our problem the use of data from over twenty experts is appropriate. The scaling approach we used to calibrate between-expert data is shown to be an appropriate mechanism for aggregating the opinions of multiple experts. The resultant model will be useful in many contexts, and can be used by managers as a tool to evaluate real sites. It can also be integrated into ecological models of change as a means of evaluating predicted changes, for example, as a measure of utility when combined with cost estimates. The basic approach demonstrated here is applicable to any ecosystem, and we discuss the opportunities and limitations of its wider use.

STUDY OBJECTIVE: The goal of this study was to evaluate demographic factors associated with increased emergency department use among people with psychiatric conditions. METHODS: This was a retrospective cohort study of all patients presenting to an urban, academic emergency department with a history of at least one mental health-related final diagnosis. RESULTS: A total of 569 people with psychiatric conditions were included in the study. Of this group, 22.1% had four or more visits within 2009. People with more than four annual visits were more likely to be over age 40, to have at least one chronic condition, to have Medicaid, and to be Black compared with those with fewer than four annual visits. DISCUSSION: The frequent-user group had fewer visits with a final psychiatric diagnosis, lower rate of psychiatric admissions, and higher rate of visits resulting in a medical admission than the infrequent-user group.

Peptide P(11)-4 (QQRFEWEFEQQ) was designed to self-assemble to form beta-sheets and nematic gels in the pH range 5-7 at concentrations > or =12.6 mM in water. This self-assembly is reversibly controlled by adjusting the pH of the solvent. It can also self-assemble into gels in biological media. This together with its biocompatibility and biodegradability make P(11)-4 an attractive building block for the fabrication of nanoscale materials with uses in, for example, tissue engineering. A limitation to large-scale production of such peptides is the high cost of solid phase chemical synthesis. We describe expression of peptide P(11)-4 in the bacterium Escherichia coli from constructs carrying tandem repeats of the peptide coding sequence. The vector pET31b+ was used to express P(11)-4 repeats fused to the ketosteroid isomerase protein which accumulates in easily recoverable inclusion bodies. Importantly, the use of auto-induction growth medium to enhance cell density and protein expression levels resulted in recovery of 2.5 g fusion protein/L culture in both shake flask and batch fermentation. Whole cell detergent lysis allowed recovery of inclusion bodies largely composed of the fusion protein. Cyanogen bromide cleavage followed by reverse phase HPLC allowed purification of the recombinant peptide with a C-terminal homoserine lactone (rP(11)-4(hsl)). This recombinant peptide formed pH dependent hydrogels, displayed beta-structure measured by circular dichroism and fibril formation observed by transmission electron microscopy.

In order to characterize connexin expression and regulation in the epidermis, we have characterized a rat epidermal keratinocyte (REK) cell line that is phenotypically similar to basal keratinocytes in that they have the ability to differentiate into organotypic epidermis consisting of a basal cell layer, 2-3 suprabasal cell layers, and a cornified layer. RT-PCR revealed that REK cells express mRNA for Cx26, Cx31, Cx31.1, Cx37, and Cx43, which mimics the reported connexin profile for rat tissue. In addition, we report the expression of Cx30, Cx30.3, Cx40, and Cx45 in rat keratinocytes, highlighting the complexity of the connexin complement in rat epidermis. Furthermore, 3-dimensional analysis of organotypic skin revealed that Cx26 and Cx43 are exquisitely regulated during the differentiation process. The life-cycle of these connexins including their expression, transport, assembly into gap junctions, internalization, and degradation are elegantly depicted in organotypic epidermis as keratinocytes proceed from differentiation to programmed cell death.
