Evaluation of patient health outcomes of a student-run free clinic in East Harlem

BACKGROUND

Most United States medical schools have affiliated student-run free clinics, but the quality of services provided in such contexts compared to national metrics is unknown. This study determines whether a student-run, attending-supervised free clinic servicing a low-income and minority race patient population in New York City can meet national metrics of care.

METHODS

Through chart review from January 1, 2020 to December 31, 2020, patient outcomes and service utilization in the Healthcare Effectiveness Data and Information Set were examined and compared to national rates of patients using Medicaid HMO or Medicare. Patients are ≥ 21 years of age, residents of East Harlem, and ineligible for health insurance because of legal residency requirements. The majority identify as Hispanic and speak Spanish as their primary language. All patients who were seen in the clinic during the 2020 calendar year were included. The primary study outcome is the number of Healthcare Effectiveness Data and Information Set measures in which patients, seen in a student-run free clinic, meet or exceed national comparisons.

RESULTS

The healthcare outcomes of 238 patients, mean age 47.8 years and 54.6% female, were examined in 18 Healthcare Effectiveness Data and Information Set measures. The student-run free clinic met or exceeded national metrics in 16 out of 18 categories.

CONCLUSIONS

The student-run free clinic met or exceeded the national standard of care according to national metrics. Evidence-based priorities have been clarified for future improvement. Other student-run free clinics should similarly evaluate the quality of their services.

Synthesis of 15N-Pyridines and Higher Mass Isotopologs via Zincke Imine Intermediates

Methods to incorporate stable radioisotopes are integral to pharmaceutical and agrochemical development. However, despite the prevalence of pyridines in candidate compounds, methods to incorporate 15N atoms within their structures are limited. Here, we present a general approach to pyridine 15N-labeling that proceeds via ring-opening to NTf-Zincke imines and then ring-closure with commercially available 15NH4Cl salts. This process functions on a range of substituted pyridines, from simple building block-type compounds to late-stage labeling of complex pharmaceuticals, and 15N-incorporation is >95% in most cases. The reactivity of the Zincke imine intermediates also enables deuteration of the pyridine C3- and C5-positions, resulting in higher mass isotopologs required for LCMS analysis of biological fluids during drug development.

Multiorgan MRI findings after hospitalisation with COVID-19 in the UK (C-MORE): a prospective, multicentre, observational cohort study

INTRODUCTION

The multiorgan impact of moderate to severe coronavirus infections in the post-acute phase is still poorly understood. We aimed to evaluate the excess burden of multiorgan abnormalities after hospitalisation with COVID-19, evaluate their determinants, and explore associations with patient-related outcome measures.

METHODS

In a prospective, UK-wide, multicentre MRI follow-up study (C-MORE), adults (aged ≥18 years) discharged from hospital following COVID-19 who were included in Tier 2 of the Post-hospitalisation COVID-19 study (PHOSP-COVID) and contemporary controls with no evidence of previous COVID-19 (SARS-CoV-2 nucleocapsid antibody negative) underwent multiorgan MRI (lungs, heart, brain, liver, and kidneys) with quantitative and qualitative assessment of images and clinical adjudication when relevant. Individuals with end-stage renal failure or contraindications to MRI were excluded. Participants also underwent detailed recording of symptoms, and physiological and biochemical tests. The primary outcome was the excess burden of multiorgan abnormalities (two or more organs) relative to controls, with further adjustments for potential confounders. The C-MORE study is ongoing and is registered with ClinicalTrials.gov, NCT04510025.

FINDINGS

Of 2710 participants in Tier 2 of PHOSP-COVID, 531 were recruited across 13 UK-wide C-MORE sites. After exclusions, 259 C-MORE patients (mean age 57 years [SD 12]; 158 [61%] male and 101 [39%] female) who were discharged from hospital with PCR-confirmed or clinically diagnosed COVID-19 between March 1, 2020, and Nov 1, 2021, and 52 non-COVID-19 controls from the community (mean age 49 years [SD 14]; 30 [58%] male and 22 [42%] female) were included in the analysis. Patients were assessed at a median of 5·0 months (IQR 4·2-6·3) after hospital discharge. Compared with non-COVID-19 controls, patients were older, living with more obesity, and had more comorbidities. Multiorgan abnormalities on MRI were more frequent in patients than in controls (157 [61%] of 259 vs 14 [27%] of 52; p<0·0001) and independently associated with COVID-19 status (odds ratio [OR] 2·9 [95% CI 1·5-5·8]; padjusted=0·0023) after adjusting for relevant confounders. Compared with controls, patients were more likely to have MRI evidence of lung abnormalities (p=0·0001; parenchymal abnormalities), brain abnormalities (p<0·0001; more white matter hyperintensities and regional brain volume reduction), and kidney abnormalities (p=0·014; lower medullary T1 and loss of corticomedullary differentiation), whereas cardiac and liver MRI abnormalities were similar between patients and controls. Patients with multiorgan abnormalities were older (difference in mean age 7 years [95% CI 4-10]; mean age of 59·8 years [SD 11·7] with multiorgan abnormalities vs mean age of 52·8 years [11·9] without multiorgan abnormalities; p<0·0001), more likely to have three or more comorbidities (OR 2·47 [1·32-4·82]; padjusted=0·0059), and more likely to have a more severe acute infection (acute CRP >5mg/L, OR 3·55 [1·23-11·88]; padjusted=0·025) than those without multiorgan abnormalities. Presence of lung MRI abnormalities was associated with a two-fold higher risk of chest tightness, and multiorgan MRI abnormalities were associated with severe and very severe persistent physical and mental health impairment (PHOSP-COVID symptom clusters) after hospitalisation.

INTERPRETATION

After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification.

A novel mutation in EROS (CYBC1) causes chronic granulomatous disease

Chronic Granulomatous Disease (CGD) is an inborn error of immunity characterised by opportunistic infection and sterile granulomatous inflammation. CGD is caused by a failure of reactive oxygen species (ROS) production by the phagocyte NADPH oxidase. Mutations in the genes encoding phagocyte NADPH oxidase subunits cause CGD. We and others have described a novel form of CGD (CGD5) secondary to lack of EROS (CYBC1), a highly selective chaperone for gp91phox. EROS-deficient cells express minimal levels of gp91phox and its binding partner p22phox, but EROS also controls the expression of other proteins such as P2X7. The full nature of CGD5 is currently unknown. We describe a homozygous frameshift mutation in CYBC1 leading to CGD. Individuals who are heterozygous for this mutation are found in South Asian populations (allele frequency = 0.00006545), thus it is not a private mutation. Therefore, it is likely to be the underlying cause of other cases of CGD.

Trainee Love and Breakup Letters to NephSIM: A Free, Mobile-Optimized, Nephrology Teaching Tool

BACKGROUND

It is not known how learners feel about free open access medical education (FOAMed) as they progress through their training from medical school to fellowship. Love and breakup letter methodology (LBM) is a technique that has been used extensively in user experience technology-based research but has not previously been used in evaluating medical education tools. LBM asks participants to creatively write a "love" or "breakup" letter to a product under study to capture their thoughts and emotions when engaging with it. We conducted qualitative analysis of data from focus groups to explore how attitudes toward a learning platform change at various training stages and to broaden our understanding of how we meet learners' needs through a nephrology FOAMed tool, NephSIM.

METHODS

Three virtual, recorded focus groups were conducted with second-year medical students, internal medicine residents, and nephrology fellows ( N =18). At the start of the focus group, participants composed and read their love and breakup letters. Semistructured discussions were then led by facilitator-driven questions and peer comments. After transcription, inductive data analysis was conducted using Braun and Clarke's six-step thematic analysis.

RESULTS

Four main themes were seen across all groups: attitudes toward teaching tool, perception of nephrology, learning needs and approach, and application to practice. Preclinical students positively viewed the opportunity to simulate the clinical setting and unanimously wrote love letters. Reactions from residents and fellows were mixed. Residents were interested in brevity and speed of learning, preferring algorithms and succinct approaches to meet their practice-based learning needs. Fellows' learning needs were driven by a desire to prepare for the nephrology board examination and review cases uncommonly seen in practice.

CONCLUSIONS

LBM provided a valuable methodology through which to identify trainee reactions to a FOAMed tool and highlighted the challenges of meeting learning needs of a continuum of trainees with a single learning platform.

Richer than Gold: the fungal biodiversity of Reserva Los Cedros, a threatened Andean cloud forest

BACKGROUND

Globally, many undescribed fungal taxa reside in the hyperdiverse, yet undersampled, tropics. These species are under increasing threat from habitat destruction by expanding extractive industry, in addition to global climate change and other threats. Reserva Los Cedros is a primary cloud forest reserve of ~ 5256 ha, and is among the last unlogged watersheds on the western slope of the Ecuadorian Andes. No major fungal survey has been done there, presenting an opportunity to document fungi in primary forest in an underrepresented habitat and location. Above-ground surveys from 2008 to 2019 resulted in 1760 vouchered collections, cataloged and deposited at QCNE in Ecuador, mostly Agaricales sensu lato and Xylariales. We document diversity using a combination of ITS barcode sequencing and digital photography, and share the information via public repositories (GenBank & iNaturalist).

RESULTS

Preliminary identifications indicate the presence of at least 727 unique fungal species within the Reserve, representing 4 phyla, 17 classes, 40 orders, 101 families, and 229 genera. Two taxa at Los Cedros have recently been recommended to the IUCN Fungal Red List Initiative (Thamnomyces chocöensis Læssøe and "Lactocollybia" aurantiaca Singer), and we add occurrence data for two others already under consideration (Hygrocybe aphylla Læssøe & Boertm. and Lamelloporus americanus Ryvarden).

CONCLUSIONS

Plants and animals are known to exhibit exceptionally high diversity and endemism in the Chocó bioregion, as the fungi do as well. Our collections contribute to understanding this important driver of biodiversity in the Neotropics, as well as illustrating the importance and utility of such data to conservation efforts.

RESUMEN

Antecedentes: A nivel mundial muchos taxones fúngicos no descritos residen en los trópicos hiper diversos aunque continúan submuestreados. Estas especies están cada vez más amenazadas por la destrucción del hábitat debido a la expansión de la industria extractivista además del cambio climático global y otras amenazas. Los Cedros es una reserva de bosque nublado primario de ~ 5256 ha y se encuentra entre las últimas cuencas hidrográficas no explotadas en la vertiente occidental de los Andes ecuatorianos. Nunca antes se ha realizado un estudio de diversidad micológica en el sitio, lo que significa una oportunidad para documentar hongos en el bosque primario, en hábitat y ubicación subrepresentatadas. El presente estudio recopila información entre el 2008 y 2019 muestreando material sobre todos los sustratos, reportando 1760 colecciones catalogadas y depositadas en el Fungario del QCNE de Ecuador, en su mayoría Agaricales sensu lato y Xylariales; además se documenta la diversidad mediante secuenciación de códigos de barras ITS y fotografía digital, la información está disponible en repositorios públicos digitales (GenBank e iNaturalist).

RESULTADOS

La identificación preliminar indica la presencia de al menos 727 especies únicas de hongos dentro de la Reserva, que representan 4 filos, 17 clases, 40 órdenes, 101 familias y 229 géneros. Recientemente dos taxones en Los Cedros se recomendaron a la Iniciativa de Lista Roja de Hongos de la UICN (Thamnomyces chocöensis Læssøe y "Lactocollybia" aurantiaca Singer) y agregamos datos de presencia de otros dos que ya estaban bajo consideración (Hygrocybe aphylla Læssøe & Boertm. y Lamelloporus americanus Ryvarden).

CONCLUSIONES

Se sabe que plantas y animales exhiben una diversidad y endemismo excepcionalmente altos en la bioregión del Chocó y los hongos no son la excepción. Nuestras colecciones contribuyen a comprender este importante promotor de la biodiversidad en el Neotrópico además de ilustrar la importancia y utilidad de dichos datos para los esfuerzos de conservación.

Learning in Tension: A Case Study Examining What Internal Medicine Residents Learn in the Ambulatory Care Setting

Introduction

Medical care of patients with complex conditions has shifted to the ambulatory setting, whereas current knowledge of resident learning is primarily based on studies from inpatient settings. Preparing trainees to adapt to this shift necessitates an understanding of what internal medicine (IM) residents currently learn during ambulatory rotations. The aim of this study is to identify what residents learn during their ambulatory care experience.

Methods

Using a qualitative instrumental case study design, the authors conducted separate focus groups with IM trainees (n = 15), supervisors (n = 16), and program directors (n = 5) from two IM programs in New York City, USA in 2019. Participants were invited via email, and focus group sessions were complemented by document analysis of ambulatory syllabi.

Results

Based on focus group commentary and document analysis, content learned in the ambulatory setting encompassed three domains; 1) patient needs, 2) the resident's role within a healthcare team, and 3) health system opportunities and limitations. Residents also learned about tensions within and between these domains including the skills needed to care for patients versus the skills acquired, a desire for ownership of patient care versus fragmented care, and time allotted versus time required.

Discussion

This study revealed two outcomes about what residents learn during their ambulatory care experience. First, learning content largely fell into three domains. Second, residents learned about the tensions between ideal care delivery and the realities of practice. These results highlight the imperative to better align curricula with clinical environments to meet the learning needs of residents.

Multi-omics identify falling LRRC15 as a COVID-19 severity marker and persistent pro-thrombotic signals in convalescence

Patients with end-stage kidney disease (ESKD) are at high risk of severe COVID-19. Here, we perform longitudinal blood sampling of ESKD haemodialysis patients with COVID-19, collecting samples pre-infection, serially during infection, and after clinical recovery. Using plasma proteomics, and RNA-sequencing and flow cytometry of immune cells, we identify transcriptomic and proteomic signatures of COVID-19 severity, and find distinct temporal molecular profiles in patients with severe disease. Supervised learning reveals that the plasma proteome is a superior indicator of clinical severity than the PBMC transcriptome. We show that a decreasing trajectory of plasma LRRC15, a proposed co-receptor for SARS-CoV-2, is associated with a more severe clinical course. We observe that two months after the acute infection, patients still display dysregulated gene expression related to vascular, platelet and coagulation pathways, including PF4 (platelet factor 4), which may explain the prolonged thrombotic risk following COVID-19.

Immunodeficiency, autoimmunity, and increased risk of B cell malignancy in humans with TRAF3 mutations

Tumor necrosis factor receptor-associated factor 3 (TRAF3) is a central regulator of immunity. TRAF3 is often somatically mutated in B cell malignancies, but its role in human immunity is not defined. Here, in five unrelated families, we describe an immune dysregulation syndrome of recurrent bacterial infections, autoimmunity, systemic inflammation, B cell lymphoproliferation, and hypergammaglobulinemia. Affected individuals each had monoallelic mutations in TRAF3 that reduced TRAF3 expression. Immunophenotyping showed that patients' B cells were dysregulated, exhibiting increased nuclear factor-κB 2 activation, elevated mitochondrial respiration, and heightened inflammatory responses. Patients had mild CD4+ T cell lymphopenia, with a reduced proportion of naïve T cells but increased regulatory T cells and circulating T follicular helper cells. Guided by this clinical phenotype, targeted analyses demonstrated that common genetic variants, which also reduce TRAF3 expression, are associated with an increased risk of B cell malignancies, systemic lupus erythematosus, higher immunoglobulin levels, and bacterial infections in the wider population. Reduced TRAF3 conveys disease risks by driving B cell hyperactivity via intrinsic activation of multiple intracellular proinflammatory pathways and increased mitochondrial respiration, with a likely contribution from dysregulated T cell help. Thus, we define monogenic TRAF3 haploinsufficiency syndrome and demonstrate how common TRAF3 variants affect a range of human diseases.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study

BACKGROUND

No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge.

METHODS

The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing.

FINDINGS

2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters.

INTERPRETATION

The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

EROS is a selective chaperone regulating the phagocyte NADPH oxidase and purinergic signalling

EROS (essential for reactive oxygen species) protein is indispensable for expression of gp91phox, the catalytic core of the phagocyte NADPH oxidase. EROS deficiency in humans is a novel cause of the severe immunodeficiency, chronic granulomatous disease, but its mechanism of action was unknown until now. We elucidate the role of EROS, showing it acts at the earliest stages of gp91phox maturation. It binds the immature 58 kDa gp91phox directly, preventing gp91phox degradation and allowing glycosylation via the oligosaccharyltransferase machinery and the incorporation of the heme prosthetic groups essential for catalysis. EROS also regulates the purine receptors P2X7 and P2X1 through direct interactions, and P2X7 is almost absent in EROS-deficient mouse and human primary cells. Accordingly, lack of murine EROS results in markedly abnormal P2X7 signalling, inflammasome activation, and T cell responses. The loss of both ROS and P2X7 signalling leads to resistance to influenza infection in mice. Our work identifies EROS as a highly selective chaperone for key proteins in innate and adaptive immunity and a rheostat for immunity to infection. It has profound implications for our understanding of immune physiology, ROS dysregulation, and possibly gene therapy.

A library of induced pluripotent stem cells from clinically well-characterized, diverse healthy human individuals

A library of well-characterized human induced pluripotent stem cell (hiPSC) lines from clinically healthy human subjects could serve as a useful resource of normal controls for in vitro human development, disease modeling, genotype-phenotype association studies, and drug response evaluation. We report generation and extensive characterization of a gender-balanced, racially/ethnically diverse library of hiPSC lines from 40 clinically healthy human individuals who range in age from 22 to 61 years. The hiPSCs match the karyotype and short tandem repeat identities of their parental fibroblasts, and have a transcription profile characteristic of pluripotent stem cells. We provide whole-genome sequencing data for one hiPSC clone from each individual, genomic ancestry determination, and analysis of mendelian disease genes and risks. We document similar transcriptomic profiles, single-cell RNA-sequencing-derived cell clusters, and physiology of cardiomyocytes differentiated from multiple independent hiPSC lines. This extensive characterization makes this hiPSC library a valuable resource for many studies on human biology.

Beyond the Extra Respiration of Phagocytosis: NADPH Oxidase 2 in Adaptive Immunity and Inflammation

Reactive oxygen species (ROS) derived from the phagocyte NADPH oxidase (NOX2) are essential for host defence and immunoregulation. Their levels must be tightly controlled. ROS are required to prevent infection and are used in signalling to regulate several processes that are essential for normal immunity. A lack of ROS then leads to immunodeficiency and autoinflammation. However, excess ROS are also deleterious, damaging tissues by causing oxidative stress. In this review, we focus on two particular aspects of ROS biology: (i) the emerging understanding that NOX2-derived ROS play a pivotal role in the development and maintenance of adaptive immunity and (ii) the effects of excess ROS in systemic disease and how limiting ROS might represent a therapeutic avenue in limiting excess inflammation.

Protease inhibitor plasma concentrations associate with COVID-19 infection

Protease inhibitors influence a range of innate immunity and inflammatory pathways. We quantified plasma concentrations of key anti-inflammatory protease inhibitors in chronic haemodialysis patients with coronavirus disease 2019 (COVID-19). The samples were collected early in the disease course to determine whether plasma protease inhibitor levels associated with the presence and severity of COVID-19. We used antibody-based immunoassays to measure plasma concentrations of C1 esterase inhibitor, alpha2-macroglobulin, antithrombin and inter-alpha-inhibitor heavy chain 4 (ITIH4) in 100 serial samples from 27 haemodialysis patients with COVID-19. ITIH4 was tested in two assays, one measuring intact ITIH4 and another also detecting any fragmented ITIH4 (total ITIH4). Control cohorts were 32 haemodialysis patients without COVID-19 and 32 healthy controls. We compared protease inhibitor concentration based on current and future COVID-19 severity and with C-reactive protein. Results were adjusted for repeated measures and multiple comparisons. Analysis of all available samples demonstrated lower plasma C1 esterase inhibitor and α2M and higher total ITIH4 in COVID-19 compared with dialysis controls. These differences were also seen in the first sample collected after COVID-19 diagnosis, a median of 4 days from diagnostic swab. Plasma ITIH4 levels were higher in severe than the non-severe COVID-19. Serum C-reactive protein correlated positively with plasma levels of antithrombin, intact ITIH4 and total ITIH4. In conclusion, plasma protease inhibitor concentrations are altered in COVID-19.

Longitudinal proteomic profiling of dialysis patients with COVID-19 reveals markers of severity and predictors of death

End-stage kidney disease (ESKD) patients are at high risk of severe COVID-19. We measured 436 circulating proteins in serial blood samples from hospitalised and non-hospitalised ESKD patients with COVID-19 (n = 256 samples from 55 patients). Comparison to 51 non-infected patients revealed 221 differentially expressed proteins, with consistent results in a separate subcohort of 46 COVID-19 patients. Two hundred and three proteins were associated with clinical severity, including IL6, markers of monocyte recruitment (e.g. CCL2, CCL7), neutrophil activation (e.g. proteinase-3), and epithelial injury (e.g. KRT19). Machine-learning identified predictors of severity including IL18BP, CTSD, GDF15, and KRT19. Survival analysis with joint models revealed 69 predictors of death. Longitudinal modelling with linear mixed models uncovered 32 proteins displaying different temporal profiles in severe versus non-severe disease, including integrins and adhesion molecules. These data implicate epithelial damage, innate immune activation, and leucocyte-endothelial interactions in the pathology of severe COVID-19 and provide a resource for identifying drug targets.

The receptor DNGR-1 signals for phagosomal rupture to promote cross-presentation of dead-cell-associated antigens

Type 1 conventional dendritic (cDC1) cells are necessary for cross-presentation of many viral and tumor antigens to CD8+ T cells. cDC1 cells can be identified in mice and humans by high expression of DNGR-1 (also known as CLEC9A), a receptor that binds dead-cell debris and facilitates XP of corpse-associated antigens. Here, we show that DNGR-1 is a dedicated XP receptor that signals upon ligand engagement to promote phagosomal rupture. This allows escape of phagosomal contents into the cytosol, where they access the endogenous major histocompatibility complex class I antigen processing pathway. The activity of DNGR-1 maps to its signaling domain, which activates SYK and NADPH oxidase to cause phagosomal damage even when spliced into a heterologous receptor and expressed in heterologous cells. Our data reveal the existence of innate immune receptors that couple ligand binding to endocytic vesicle damage to permit MHC class I antigen presentation of exogenous antigens and to regulate adaptive immunity.

Plasma Lectin Pathway Complement Proteins in Patients With COVID-19 and Renal Disease

We do not understand why non-white ethnicity and chronic kidney disease increase susceptibility to COVID-19. The lectin pathway of complement activation is a key contributor to innate immunity and inflammation. Concentrations of plasma lectin pathway proteins influence pathway activity and vary with ethnicity. We measured circulating lectin proteins in a multi-ethnic cohort of chronic kidney disease patients with and without COVID19 infection to determine if lectin pathway activation was contributing to COVID19 severity. We measured 11 lectin proteins in serial samples from a cohort of 33 patients with chronic kidney impairment and COVID19. Controls were single plasma samples from 32 patients on dialysis and 32 healthy individuals. We demonstrated multiple associations between recognition molecules and associated proteases of the lectin pathway and COVID-19, including COVID-19 severity. Some of these associations were unique to patients of Asian and White ethnicity. Our novel findings demonstrate that COVID19 infection alters the concentration of plasma lectin proteins and some of these changes were linked to ethnicity. This suggests a role for the lectin pathway in the host response to COVID-19 and suggest that variability within this pathway may contribute to ethnicity-associated differences in susceptibility to severe COVID-19.

Temporal changes in complement activation in haemodialysis patients with COVID-19 as a predictor of disease progression

BACKGROUND

Complement activation may play a pathogenic role in patients with severe coronavirus disease 2019 (COVID-19) by contributing to tissue inflammation and microvascular thrombosis.

METHODS

Serial samples were collected from patients receiving maintenance haemodialysis (HD). Thirty-nine patients had confirmed COVID-19 and 10 patients had no evidence of COVID-19. Plasma C5a and C3a levels were measured using enzyme-linked immunosorbent assay.

RESULTS

We identified elevated levels of plasma C3a and C5a in HD patients with severe COVID-19 compared with controls. Serial sampling identified that C5a levels were elevated prior to clinical deterioration in patients who developed severe disease. C3a more closely mirrored both clinical and biochemical disease severity.

CONCLUSIONS

Our findings suggest that activation of complement plays a role in the pathogenesis of COVID-19, leading to endothelial injury and lung damage. C5a may be an earlier biomarker of disease severity than conventional parameters such as C-reactive protein and this warrants further investigation in dedicated biomarker studies. Our data support the testing of complement inhibition as a therapeutic strategy for patients with severe COVID-19.

Loss of IL-10 signaling in macrophages limits bacterial killing driven by prostaglandin E2

Cytokines and lipid mediators are key regulators of inflammation; but how they are mechanistically linked is poorly understood. Here, Mukhopadhyay et al. show a novel regulation between cytokine IL-10 and lipid mediator PGE2 that functionally connects them to intestinal inflammation.

Loss of IL-10 signaling in macrophages (Mφs) leads to inflammatory bowel disease (IBD). Induced pluripotent stem cells (iPSCs) were generated from an infantile-onset IBD patient lacking a functional IL10RB gene. Mφs differentiated from IL-10RB^−/− iPSCs lacked IL-10RB mRNA expression, were unable to phosphorylate STAT3, and failed to reduce LPS induced inflammatory cytokines in the presence of exogenous IL-10. IL-10RB^−/− Mφs exhibited a striking defect in their ability to kill Salmonella enterica serovar Typhimurium, which was rescuable after experimentally introducing functional copies of the IL10RB gene. Genes involved in synthesis and receptor pathways for eicosanoid prostaglandin E2 (PGE2) were more highly induced in IL-10RB^−/− Mφs, and these Mφs produced higher amounts of PGE2 after LPS stimulation compared with controls. Furthermore, pharmacological inhibition of PGE2 synthesis and PGE2 receptor blockade enhanced bacterial killing in Mφs. These results identify a regulatory interaction between IL-10 and PGE2, dysregulation of which may drive aberrant Mφ activation and impaired host defense contributing to IBD pathogenesis.

Lentiviral gene therapy rescues p47phox chronic granulomatous disease and the ability to fight Salmonella infection in mice

Chronic granulomatous disease (CGD) is an inherited primary immunodeficiency disorder characterised by recurrent and often life-threatening infections and hyperinflammation. It is caused by defects of the phagocytic NADPH oxidase, a multicomponent enzyme system responsible for effective pathogen killing. A phase I/II clinical trial of lentiviral gene therapy is underway for the most common form of CGD, X-linked, caused by mutations in the gp91^phox subunit of the NADPH oxidase. We propose to use a similar strategy to tackle p47^phox-deficient CGD, caused by mutations in NCF1, which encodes the p47^phox cytosolic component of the enzymatic complex. We generated a pCCLCHIM-p47^phox lentiviral vector, containing the chimeric Cathepsin G/FES myeloid promoter and a codon-optimised version of the human NCF1 cDNA. Here we show that transduction with the pCCLCHIM-p47^phox vector efficiently restores p47^phox expression and biochemical NADPH oxidase function in p47^phox-deficient human and murine cells. We also tested the ability of our gene therapy approach to control infection by challenging p47^phox-null mice with Salmonella Typhimurium, a leading cause of sepsis in CGD patients, and found that mice reconstituted with lentivirus-transduced hematopoietic stem cells had a reduced bacterial load compared with untreated mice. Overall, our results potentially support the clinical development of a gene therapy approach using the pCCLCHIM-p47^phox vector.

An Innovative Consulting Group for Sharing Expertise on Launching and Sustaining Student-Run Free Clinics: A Model for Building Student-Run Endeavors

Student-run, physician-supervised free clinics (SRFCs) provide essential healthcare services for many uninsured and underinsured patients in the USA. While SRFCs serve diverse populations and offer distinct services, they face many similar barriers to successful clinic operation. Historically, the sharing of best practices and development strategies across SRFCs has been limited and insufficient for both new and emerging free clinics. To address these challenges, in 2015, the East Harlem Health Outreach Program (EHHOP) at the Icahn School of Medicine at Mount Sinai formed the EHHOP Consulting Group (ECG), with the goal of providing client SRFCs individualized support from medical students. ECG draws from the experience of EHHOP and other veteran SRFCs to provide customized solutions to best address client SRFC needs. Here, we describe ECG's inception, structure, and consulting work with client SRFCs. We propose that this interactive, longitudinal model can be adapted to other healthcare trainee initiatives where cross-institutional collaboration could prove beneficial.

Expression, purification and metal utilization of recombinant SodA from Borrelia burgdorferi

Borrelia are microaerophilic spirochetes capable of causing multisystemic diseases such as Lyme disease and Relapsing Fever. The ubiquitous Fe/Mn-dependent superoxide dismutase (SOD) provides essential protection from oxidative damage by the superoxide anion. Borrelia possess a single SOD enzyme - SodA that is essential for virulence, providing protection against host-derived reactive oxygen species (ROS). Here we present a method for recombinant expression and purification of Borrelia burgdorferi SodA in E. coli. Metal exchange or insertion into the Fe/Mn-SOD is inhibited in the folded state. We therefore present a method whereby the recombinant Borrelia SodA binds to Mn under denaturing conditions and is subsequently refolded by a reduction in denaturant. SodA purified by metal affinity chromatography and size exclusion chromatography reveals a single band on SDS-PAGE. Protein folding is confirmed by circular dichroism. A coupled enzyme assay demonstrates SOD activity in the presence of Mn, but not Fe. The apparent molecular weight determined by size exclusion corresponds to a dimer of SodA; a homology model of dimeric SodA is presented revealing a surface Cys distal to the dimer interface. The method presented of acquiring a target metal under denaturing conditions may be applicable to the refolding of other metal-binding proteins.

The Role of Early Immersive Culture Mixing in Cultural Identifications of Multiculturals

Becoming multicultural through early immersive culture mixing (EICM)—i.e., growing up with a mix of cultures that coexist and interact to form an emergent hybrid culture within one’s home—is a rapidly rising phenomenon in many parts of the world. This phenomenon calls for new research that recognizes the possibility of identification with a hybrid culture as well as the distinct cultures from which the hybrid culture derives. This article extends previous research into psychological variation among multiculturals based on the process of EICM, by investigating how EICM influences hybrid cultural identification and distinct cultural identification. In addition, we examine how EICM relates to the components of identity integration—blendedness and harmony. Across two studies of Chinese-Australian multiculturals, we found that whereas EICM was positively associated with multicultural participants’ identification with a hybrid culture and Australian culture, it was not related to their identification with Chinese culture. Findings also indicated that EICM positively predicted identity blendedness, but EICM did not show a clear link with identity harmony. We discuss the implications of our research for advancing EICM theory and helping to forge new research directions in cultural identification.

How the phagocyte NADPH oxidase regulates innate immunity

The phagocyte NADPH oxidase is a multi subunit protein complex that generates reactive oxygen species at cell membranes and within phagosomes. It is essential for host defence as evidenced by the severe immunodeficiency syndrome caused by a loss of one of the subunits. This is known as chronic granulomatous disease (CGD). However, the phagocyte NADPH oxidase also has a key role to play in regulating immunity and it is notable that chronic granulomatous disease is also characterised by autoimmune and autoinflammatory manifestations. This is because reactive oxygen species play a role in regulating signalling through their ability to post-translationally modify amino acid residues such as cysteine and methionine. In this review, I will outline the major aspects of innate immunity that are regulated by the phagocyte NADPH oxidase, including control of transcription, autophagy, the inflammasome and type 1 interferon signalling.

Antibody repertoire analysis in polygenic autoimmune diseases

High-throughput sequencing of the DNA/RNA encoding antibody heavy- and light-chains is rapidly transforming the field of adaptive immunity. It can address key questions, including: (i) how the B-cell repertoire differs in health and disease; and (ii) if it does differ, the point(s) in B-cell development at which this occurs. The advent of technologies, such as whole-genome sequencing, offers the chance to link abnormalities in the B-cell antibody repertoire to specific genomic variants and polymorphisms. Here, we discuss the current research using B-cell antibody repertoire sequencing in three polygenic autoimmune diseases where there is good evidence for a pathological role for B-cells, namely systemic lupus erythematosus, multiple sclerosis and rheumatoid arthritis. These autoimmune diseases exhibit significantly skewed B-cell receptor repertoires compared with healthy controls. Interestingly, some common repertoire defects are shared between diseases, such as elevated IGHV4-34 gene usage. B-cell clones have effectively been characterized and tracked between different tissues and blood in autoimmune disease. It has been hypothesized that these differences may signify differences in B-cell tolerance; however, the mechanisms and implications of these defects are not clear.

NBEAL2 is required for neutrophil and NK cell function and pathogen defense

Mutations in the human NBEAL2 gene cause gray platelet syndrome (GPS), a bleeding diathesis characterized by a lack of α granules in platelets. The functions of the NBEAL2 protein have not been explored outside platelet biology, but there are reports of increased frequency of infection and abnormal neutrophil morphology in patients with GPS. We therefore investigated the role of NBEAL2 in immunity by analyzing the phenotype of Nbeal2-deficient mice. We found profound abnormalities in the Nbeal2-deficient immune system, particularly in the function of neutrophils and NK cells. Phenotyping of Nbeal2-deficient neutrophils showed a severe reduction in granule contents across all granule subsets. Despite this, Nbeal2-deficient neutrophils had an enhanced phagocyte respiratory burst relative to Nbeal2-expressing neutrophils. This respiratory burst was associated with increased expression of cytosolic components of the NADPH oxidase complex. Nbeal2-deficient NK cells were also dysfunctional and showed reduced degranulation. These abnormalities were associated with increased susceptibility to both bacterial (Staphylococcus aureus) and viral (murine CMV) infection in vivo. These results define an essential role for NBEAL2 in mammalian immunity.

The phagocyte respiratory burst: Historical perspectives and recent advances

When exposed to certain stimuli, phagocytes (including neutrophils, macrophages and eosinophils) undergo marked changes in the way they handle oxygen. Firstly, their rate of oxygen uptake increases greatly. This is accompanied by (i) the production of large amounts of superoxide and hydrogen peroxide and (ii) the metabolism of large quantities of glucose through the hexose monophosphate shunt. We now know that the oxygen used is not for respiration but for the production of powerful microbiocidal agents downstream of the initial production of superoxide. Concomitantly, glucose is oxidised through the hexose monophosphate shunt to re-generate the NADPH that has been consumed through the reduction of molecular oxygen to generate superoxide. This phagocyte respiratory burst is generated by an NADPH oxidase multi-protein complex that has a catalytic core consisting of membrane-bound gp91phox (CYBB) and p22phox (CYBA) sub-units and cytosolic components p47phox (NCF1), p67phox (NCF2) and p40phox (NCF4). Finally, another cytosolic component, the small G-protein Rac (Rac2 in neutrophils and Rac1 in macrophages) is also required for full activation. The importance of the complex in host defence is underlined by chronic granulomatous disease, a severe life-limiting immunodeficiency caused by mutations in the genes encoding the individual subunits. In this review, I will discuss the experimental evidence that underlies our knowledge of the respiratory burst, outlining how elegant biochemical analysis, coupled with study of patients deficient in the various subunits has helped elucidate the function of this essential part of innate immunity. I will also discuss some exciting recent studies that shed new light on how the abundance of the various components is controlled. Finally, I will explore the emerging role of reactive oxygen species such as superoxide and hydrogen peroxide in the pathogenesis of major human diseases including auto-inflammatory diseases.

A model for integrating the assessment and management of geriatric syndromes into internal medicine continuity practice: 5-year report

A geriatric ambulatory curriculum was created to improve internal medicine residents' care of geriatric patients. Second-year residents met for a 3-hour session weekly for 4 consecutive weeks during a block rotation with faculty geriatricians for a curriculum focused on dementia, falls, and urinary incontinence. After a 1-hour case-based didactic session, residents applied learned content and concepts to patient consultations. Consultative encounters were precepted by faculty and shared with the team. After completing our curriculum, residents reported knowledge acquired and enhanced evaluation and management skills of these three syndromes and were more likely to use all recommended screening tests in future practice. This article describes the process and strategies guiding development of a successful ambulatory geriatric curriculum model that can be embedded into preexisting internal medicine clinics to help future internists to better manage these and other common geriatric syndromes.

Eros is a novel transmembrane protein that controls the phagocyte respiratory burst and is essential for innate immunity

The phagocyte respiratory burst is crucial for innate immunity. The transfer of electrons to oxygen is mediated by a membrane-bound heterodimer, comprising gp91phox and p22phox subunits. Deficiency of either subunit leads to severe immunodeficiency. We describe Eros (essential for reactive oxygen species), a protein encoded by the previously undefined mouse gene bc017643, and show that it is essential for host defense via the phagocyte NAPDH oxidase. Eros is required for expression of the NADPH oxidase components, gp91phox and p22phox Consequently, Eros-deficient mice quickly succumb to infection. Eros also contributes to the formation of neutrophil extracellular traps (NETS) and impacts on the immune response to melanoma metastases. Eros is an ortholog of the plant protein Ycf4, which is necessary for expression of proteins of the photosynthetic photosystem 1 complex, itself also an NADPH oxio-reductase. We thus describe the key role of the previously uncharacterized protein Eros in host defense.

Interpreter training for medical students: pilot implementation and assessment in a student-run clinic

BACKGROUND

Trained medical interpreters are instrumental to patient satisfaction and quality of care. They are especially important in student-run clinics, where many patients have limited English proficiency. Because student-run clinics have ties to their medical schools, they have access to bilingual students who may volunteer to interpret, but are not necessarily formally trained.

METHODS

To study the feasibility and efficacy of leveraging medical student volunteers to improve interpretation services, we performed a pilot study at the student-run clinic at the Icahn School of Medicine at Mount Sinai. In each fall semester in 2012-2015, we implemented a 6-h course providing didactic and interactive training on medical Spanish interpreting techniques and language skills to bilingual students. We then assessed the impact of the course on interpreter abilities.

RESULTS

Participants' comfort levels, understanding of their roles, and understanding of terminology significantly increased after the course (p < 0.05), and these gains remained several months later (p < 0.05) and were repeated in an independent cohort. Patients and student clinicians also rated participants highly (averages above 4.5 out of 5) on these measures in real clinical encounters.

CONCLUSIONS

These findings suggest that a formal interpreter training course tailored for medical students in the setting of a student-run clinic is feasible and effective. This program for training qualified student interpreters can serve as a model for other settings where medical students serve as interpreters.

Item-Difficulty Sequence in Achievement Examinations: Examinees' Preferences and Test-Taking Strategies

Elementary, secondary school, and university students were asked for the test-taking strategy usually used in taking an achievement test and for the sequence of difficulty preferred for achievement test items. The majority preferred an easy-to-hard strategy with items in order-presented as second choice, and the hard-to-easy strategy chosen least often. No conclusions were drawn as to the effect of students' usual test-taking strategies on research with various item-difficulty sequences. The data on students' preferences for item sequences support the use of the easy-to-hard or random arrangement over the hard-to-easy.

What Is Implementation Science and What Forces Are Driving a Change in Medical Education?

Evidence-based interventions to improve health care and medical education face multiple complex barriers to adoption and success. Implementation science focuses on the period following research dissemination, which is necessary but insufficient to address important gaps in clinician performance and patient outcomes. This article describes the forces on health care institutions, medical schools, physician clinicians, and trainees that have created the imperative to design educational interventions to address the gap between evidence and practice. These forces include accreditation, certification, licensure, and regulatory and research funding initiatives focused on improving the quality of health professions education and clinical practice. Medical educators must expand their focus on "what to change" to include "how to change" in order to prepare health care professionals and institutions to effectively adopt new evidence-based practices to improve patient, and ultimately population, outcomes.

Communication In Intercultural Interaction

This study examined the communication styles of East Asians and Anglo-European New Zealanders (Pakeha). Results indicated that in general, Asians exhibited more sociocentric communication behavior whereas Pakeha exhibited more idiocentric behavior. In intercultural interactions, both the frequency and intensity of these behavior styles were exacerbated. Results further indicated that task accomplishment required more time in the intercultural condition as compared to homogeneous conditions. Implications for international management research and practice are discussed.

Effect of Culture on Situational Determinants of Exchange Behavior in Organizations

This study examined the moderating effect of national culture on the relationship between a key situational indicator (job satisfaction) and the exchange behaviors of employees. The main effect of job satisfaction on the outcome behaviors of exit, voice, loyalty, and neglect was consistent in Indonesia and New Zealand suggesting a possible universal relationship. However, the cultural group of participants (Indonesia or New Zealand) moderated the influence of job satisfaction on all outcomes with the exception of voice. The implications of these results for theory and practice are discussed.

Causal Attribution in an Intercultural Interaction

Causal attribution for three different levels of adaptive behaviour by a foreign (Japanese) manager to the cultural expectations of host country (United States) subordinates was examined in an experimental setting. Two methods, written descriptions of the intercultural interaction (scripts) and direct observation (videotapes produced from the scripts), were used to present the behaviour. A main effect was found for the level of adaptive behaviour on attribution to internal causes. There was no significant difference in the accuracy of participants' memory of critical behaviours based on the method used to present the behaviours. However, participants' recognition memory was affected by the level of cultural adaptation to which they were exposed. Also, a significant interaction between method of stimulus presentation and level of cultural adaptation on causal attribution indicated that the mode of presentation may have affected the psychological process under investigation. Implications for the study of intercultural interactions are discussed.

Cultural Diversity and Work Group Effectiveness

Changes in workforce demographics resulting from globalization, combined with the rising popularity of team-based management techniques, has resulted in a practical concern with the management of multicultural groups. In this experimental study, three mechanisms that are proposed to influence group effectiveness are examined. Results supported the notion that the cultural diversity of the group, the sociocultural norms of group members, and their relative cultural distance from each other influence work group effectiveness. Culturally homogeneous groups had higher performance than did culturally heterogeneous groups on five group tasks. The degree of collectivist orientations of group members was directly related to their evaluations of group processes, and their relative cultural distance from each other influenced their perceptions of group receptiveness. A comparison of the results of this study with previous research indicates the importance of the group task and process-related feedback on group performance. Implications of these findings are discussed.

Domain and Development of Cultural Intelligence

The potential for defining a reliable measure of a cross-cultural facet of intelligence has enormous implications for explaining and predicting the increasingly prevalent cross-cultural interactions that occur in business settings. In this article, the author presents a definition of cultural intelligence (CQ) that explicitly introduces the concept of mindfulness as a key component that links knowledge with behavioral capability. It builds on previous definitions by grounding the conceptualization in the cognitive domain and differentiating CQ as a capability that includes skilled behavior. However, alternatives to previous conceptualizations with regard to the constituent elements and their relationship to each other are presented with a view toward a tighter specification of the construct. Also, a developmental stage model of CQ is outlined. Implications for the assessment of CQ are discussed.

Residents' Perspectives on Rewards and Challenges of Caring for Ambulatory Care Patients Living With Chronic Illness: Findings From Three Academic Health Centers

PURPOSE

To elicit residents' perspectives on rewards and challenges of caring for ambulatory patients with chronic illness and ways to improve their education in caring for these patients.

METHOD

The authors conducted a qualitative study with internal medicine residents during ambulatory medicine block rotations at three academic health centers from October 2011 through February 2012. Focus group questions covered rewards and challenges of caring for patients with chronic illness and strengths and weaknesses of residency education therein, and the Chronic Care Model provided a framework for interpretation. Qualitative analysis was used to identify themes.

RESULTS

Five focus groups were conducted with 28 residents. Discussions yielded 224 comments, which were categorized into 5 domains and 36 themes. Twelve themes related to perceptions of challenges in providing care, and 3 themes related to perceptions of rewards in providing care. Eight themes focused on strategies to improve the patient experience. Strengths of the residency program were identified in 7 themes. Six themes related to ways for improving learning about caring for patients with chronic disease in the ambulatory setting.

CONCLUSIONS

Residents perceived rewards, challenges, and barriers in caring for patients with chronic illness in the ambulatory setting, from providers' and patients' perspectives. They have developed strategies to provide effective patient care. Residents identified best practices in their residency for resident education and patient care and also made suggestions for improvement. Findings have significant implications for residency education and practice redesign in the 21st century for care of patients with chronic illness.

The role of self-concept in cross-cultural communication

Empirical evidence supports the notion that communication behaviors in intercultural encounters are effectively extensions of cultural values as well as epistemologies. Study 1 established communication behaviors of Asians and New Zealanders (NZs) as consistent with vertical collectivism and horizontal individualism, respectively. In particular, argumentativeness is positively related to independent self-construal (SC) and negatively related to interdependent SC. This supports Markus and Kitayama’s SC theory. Study 2 showed that NZs exhibited more idiocentric and argumentative behavior, while Asians displayed more sociocentric and less argumentative behavior during two actual interactions; specifically, participants diverged in their communication styles to be more consistent with their cultural values during intercultural interactions. Analyses of decision outcomes provide support that culture moderates cognitive consistency behaviors such that NZs exhibited more inconsistency-reduction behaviors, which is rooted in adherence to noncontradiction. In contrast, Asians exhibited more inconsistency-support behaviors, suggesting that naive dialecticism rooted in acceptance of contradiction is customary in Asian social interaction.

In the form of a guideline, this article describes one such intervention, interprofessional education (IPE), which is a common intervention in health professions education. IPE is an opportunity for individuals of multiple professions to interact to learn together, to break down professional silos, and to achieve interprofessional learning outcomes in the service of high-value patient care. Based on a review of recent evidence and a facilitated discussion with US and Canadian experts, we describe IPE, its terminology, and other important information about the intervention. We encourage leaders and researchers to consider and to build on this guideline as they plan, implement, evaluate, and report IPE efforts. Clear and consistent use of terminology is imperative, along with complete and accurate descriptions of interventions, to improve the use and study of IPE.

Society for Academic Continuing Medical Education Intervention Guideline Series: Guideline 1, Performance Measurement and Feedback

The Society for Academic Continuing Medical Education commissioned a study to clarify and, if possible, to standardize the terminology for a set of important educational interventions. In the form of a guideline, this article describes one such intervention, performance measurement and feedback, which is a common intervention in health professions education. In the form of a summary report, performance measurement and feedback is an opportunity for clinicians to view data about the care they provide compared with some standard and often with peer and benchmark comparisons. Based on a review of recent evidence and a facilitated discussion with the US and Canadian experts, we describe proper terminology for performance measurement and feedback and other important information about the intervention. We encourage leaders and researchers to consider and build on this guideline as they plan, implement, evaluate, and report efforts with performance measurement and feedback. Clear and consistent use of terminology is imperative, along with complete and accurate descriptions of interventions, to improve the use and study of performance measurement and feedback.

A user-editable web-based platform to streamline clinical information flow

Frequent turnover of staff in medical clinics creates challenges in the maintenance of clinical protocols, workflows, and information management. Care coordination between providers in such a setting can be complex; disruptions in communication may lead to poorer health outcomes and patient satisfaction. Furthermore, protocols change frequently in response to new guidelines, which demands rapid updates to maintain compliance. To address these challenges, we developed an intuitive, end-user editable web-based knowledge management system optimized for use on mobile devices. The resulting system served as a point of care information storage and retrieval tool that providers can reference quickly for operational tasks. Since launch, the platform has allowed our clinic to consolidate knowledge banks, standardize staff training, and streamline information flow during clinic, and is now used extensively by clinic staff. During a one-year period, 175 new pages have been created and 1686 edits have been submitted by users. We posit that a mobile platform for clinical information flow management has significant potential to improve information maintenance and facilitate transfer of up-to-date clinical protocols to new personnel.

n-Culturals, the next cross-cultural challenge

This article advances current conceptualizations of multicultural identities by identifying constituent elements of multicultural identity as knowledge, identification, internalization, and commitment. This new conceptualization is labeled n- Culturalism and posits that there are individuals who operate at the intersection of multiple cultures by maintaining salience of their multiple cultural identities. We illustrate that n-Culturals are assets to organizations because they are creative synthesizers that are able to facilitate organizational goals and can also serve as models for others who are struggling in a multicultural environment. This article provides some solutions to managing multicultural challenges in organizations, such as conflicting values and identities. It also offers solutions on how individuals and organizations can leverage their identities in relation to the multiculturalism continuum to achieve desired workplace outcomes. Further, we introduce the multicultural mentor modeling program for organizations, which, if implemented, can help struggling multiculturals to address challenges in their social cognition and to develop appropriate and effective behaviors in and outside of the workplace.
