The ID Digital Institute: Building a digital education toolset and community.

Organic digital education (ODE) includes online medical education content that can take various forms, such as blogs, social media, videos, podcasts, or infographics. Multimedia ODE platforms have unique benefits and have quickly become an essential part of medical education. Modern medical educators with competency in digital teaching modalities can leverage these for teaching as well as career development and dissemination of scientific research. The ID Digital Institute is a digital education program with a curriculum designed to equip infectious diseases (ID) professionals with the skills to appraise, create, curate, and integrate ODE into their teaching and career. We share the structure, content, and lessons learned from the ID Digital Institute program. We also illustrate how digital education skills can present unique opportunities to align with current and future transplant and immunocompromised host infectious diseases education efforts.

The performance of bronchoalveolar lavage Aspergillus PCR testing in solid organ transplant recipients with invasive pulmonary aspergillosis.

BACKGROUND: Invasive aspergillosis affects solid organ transplant (SOT) recipients, carrying a high risk of mortality and morbidity in this population. Rapid and accurate diagnosis is essential to ensure the initiation of correct antifungal therapy. We aimed to evaluate the performance of the bronchoalveolar lavage (BAL) Eurofins Viracor Aspergillus PCR (AspPCR) in diagnosing invasive pulmonary aspergillosis (IPA) in SOT recipients. METHODS: We conducted a multicenter retrospective study of SOT recipients in Arizona from February 2019 to December 2022 who had AspPCR done at the time of the clinical encounter. Probable IPA was defined as a positive BAL culture with Aspergillus spp. with clinical and imaging findings of IPA per EORTC/MSGERC criteria. RESULTS: Ninety-nine SOT recipients with 131 encounters with BAL AspPCR testing were included. The median age was 66, the majority were White, non-Hispanics (60%), and males (66%). Among the participants, 93 lung transplant recipients with 87 of the encounters received antifungal prophylaxis active against Aspergillus spp. Sixty-four encounters had BAL galactomannan (GM), all of which had BAL GM <1 OD, and one case had a serum GM of 10 OD. Nine cases met the definition of IPA. The sensitivity of the BAL AspPCR was 67% (95% CI 30%-93%), and the specificity was 98% (95% CI 93%-99%). CONCLUSION: BAL AspPCR had moderate sensitivity and high specificity in identifying IPA in our cohort of SOT recipients. Further studies in populations with a higher prevalence of IPA are needed to evaluate the performance of this test.

Candidemia Following Severe COVID-19 in Hospitalised and Critical Ill Patients: A Systematic Review and Meta-Analysis.

RATIONALE: The epidemiology and clinical impact of COVID-19-associated candidemia (CAC) remained uncertain, leaving gaps in understanding its prevalence, risk factors and outcomes. METHODS: A systematic review and meta-analysis were conducted by searching PubMed, Embase and Scopus for reports of CAC prevalence, risk factors and clinical outcomes up to June 18, 2024. The generalised linear mixed model was employed to determine the prevalence and 95% confidence intervals (CIs). The risk factors and clinical outcomes were compared between patients with and without CAC using the inverse variance method. RESULTS: From 81 studies encompassing 29 countries and involving 351,268 patients, the global prevalence of CAC was 4.33% (95% Cl, 3.16%-5.90%) in intensive care unit (ICU) patients. In ICUs, the pooled prevalence of CAC in high-income countries was significantly higher than that of lower-middle-income countries (5.99% [95% Cl, 4.24%-8.40%] vs. 2.23% [95% Cl, 1.06%-4.61%], p = 0.02). Resistant Candida species, including C. auris, C. glabrata (Nakaseomyces glabratus) and C. krusei (Pichia kudriavzveii), constituted 2% of ICU cases. The mortality rate for CAC was 68.40% (95% Cl, 61.86%-74.28%) among ICU patients. Several risk factors were associated with CAC, including antibiotic use, central venous catheter placement, dialysis, mechanical ventilation, tocilizumab, extracorporeal membrane oxygenation and total parenteral nutrition. Notably, the pooled odds ratio of tocilizumab was 2.59 (95% CI, 1.44-4.65). CONCLUSIONS: The prevalence of CAC is substantial in the ICU setting, particularly in high-income countries. Several risk factors associated with CAC were identified, including several that are modifiable, offering the opportunity to mitigate the risk of CAC.

Controlling infections in hospitalized pretransplant candidates.

PURPOSE OF REVIEW: Infections in hospitalized patients awaiting solid organ transplantation can pose complicated diagnostic and therapeutic challenges. Goals of management include stabilizing the patient, treating or controlling infections, and decreasing the risk of reactivation of infection after transplant. RECENT FINDINGS: Groups such as The Organ Procurement and Transplantation Network, American Society of Transplantation Infectious Diseases Community of Practice and the European Society of Clinical Microbiology and Infectious Diseases have updated their guidelines on screening and treatment of infection in transplant candidates. There are also recent developments in therapeutic options for tuberculosis, COVID-19, Clostridioides difficile colitis, bloodstream infections, and other common infections. SUMMARY: Ideally, antimicrobial therapy should be complete prior to transplantation. In situations in which completion of therapy prior to transplant is not feasible, therapy may need to be prolonged or modified. In most situations, infections can be managed similarly to the general population, although some infections, particularly fungal and mycobacterial, require a different management approach. We review disease- and organ-specific management.

Prevalence of Ocular Candidiasis and Candida Endophthalmitis in Patients With Candidemia: A Systematic Review and Meta-Analysis.

BACKGROUND: Infectious diseases and ophthalmology professional societies have disagreed regarding ocular screening in patients with candidemia. We aimed to summarize the current evidence on the prevalence of ocular candidiasis (OC) and Candida endophthalmitis (CE) according to the standardized definitions. METHODS: A literature search was conducted from the inception date through 16 October 2022 using PubMed, Embase, and SCOPUS. Pooled prevalence of ocular complications was derived from generalized linear mixed models (PROSPERO CRD42022326610). RESULTS: A total of 70 and 35 studies were included in the meta-analysis for OC and concordant CE (chorioretinitis with vitreous involvement), respectively. This study represented 8599 patients with candidemia who underwent ophthalmologic examination. Pooled prevalences (95% CI) of OC, overall CE, concordant CE, and discordant CE were 10.7% (8.4-13.5%), 3.1% (2.1-4.5%), 1.8% (1.3-2.6%), and 7.4% (4.5-12%) of patients screened, respectively. Studies from Asian countries had significantly higher concordant CE prevalence (95% CI) of patients screened (3.6%; 2.9-4.6%) compared with studies from European countries (1.4%; .4-5%) and American countries (1.4%; .9-2.2%) (P <.01). Presence of total parenteral nutrition and Candida albicans was associated with CE, with pooled odds ratios (95% CI) of 6.92 (3.58-13.36) and 3.02 (1.67-5.46), respectively. CONCLUSIONS: Prevalence of concordant CE overall and among Asian countries was 2 and 4 times higher than the prevalence previously reported by the American Academy of Ophthalmology (AAO) of <0.9%, respectively. There is an urgent need to study optimal screening protocols and to establish joint recommendations by the Infectious Diseases Society of America and AAO.

Around the World in 60 Minutes: How a Virtual Morning Report has Created an International Community for Clinical Reasoning and Medical Education.

Problem: Traditionally, clinical reasoning is developed with purposeful exposure to clinical problems through case-based learning and clinical reasoning conferences that harvest a collaborative exchange of information in real-life settings. While virtual platforms have greatly expanded access to remote clinical learning, case-based clinical reasoning opportunities are scarce in low and middle income countries. Intervention: The Clinical Problem Solvers (CPSolvers), a nonprofit organization focused on clinical reasoning education, launched Virtual Morning Report (VMR) during the COVID-19 pandemic. VMR is an open-access, case-based clinical reasoning virtual conference on the Zoom platform modeled after an academic morning report format available to participants worldwide. The authors conducted 17 semi-structured interviews with CPSolvers' VMR participants from 10 different countries to explore the experiences of the international participants of VMR. Context: The CPSolvers was founded by US physicians and has now expanded to include international members throughout all levels of the organization. VMR is open-access to all learners. Preliminary survey data collected from VMR sessions revealed 35% of the attendees were from non-English speaking countries and 53% from non US countries. Impact: Analysis generated four themes that captured the experiences of international participants of VMR: 1) Improving clinical reasoning skills where participants had little to no access to this education or content; 2) Creating a global community from a diverse, safe, and welcoming environment made possible by the virtual platform; 3) Allowing learners to become agents of change by providing tools and skills that are directly applicable in the setting in which they practice medicine; 4) Establishing a global platform, with low barriers to entry and open-access to expertise and quality teaching and content. Study participants agreed with the themes, supporting trustworthiness. Lessons Learned: Findings suggest VMR functions as and has grown into a global community of practice for clinical reasoning. The authors propose strategies and guiding principles based on the identified themes for educators to consider when building effective global learning communities. In an interdependent world where the virtual space eliminates the physical boundaries that silo educational opportunities, emphasis on thoughtful implementation of learning communities in a global context has the potential to reduce medical education disparities in the clinical reasoning space and beyond.

A review of transplant infectious diseases and pediatric transplant infectious diseases curriculum.

PURPOSE OF REVIEW: As the volume and complexity of solid organ and hematopoietic stem cell transplantation continue to see rapid growth, the training of a specialized transplant infectious diseases physician workforce is of increasing interest and importance. This review provides an overview of the evolution of transplant infectious diseases training programs, essential elements of training, as well as future needs. RECENT FINDINGS: Despite the first publication of a transplant infectious diseases curriculum in 2010, more recent surveys of infectious diseases trainees have identified gaps in didactic curriculum, donor and recipient assessment, and safe living practices. SUMMARY: This review of transplant infectious diseases training summarizes growth through the decades, the current landscape of recommend training elements, suggested areas for continued development and expansion in training as well as novel methodologies to reach a modern trainee audience.

Coronavirus Disease 2019-Associated Pulmonary Aspergillosis in Mechanically Ventilated Patients.

BACKGROUND: Coronavirus disease 2019 (COVID-19)-associated pulmonary aspergillosis (CAPA) occurs in critically ill patients with COVID-19. Risks and outcomes remain poorly understood. METHODS: A retrospective cohort study of mechanically ventilated adult patients with COVID-19 admitted to 5 Johns Hopkins hospitals was conducted between March and August 2020. CAPA was defined using composite clinical criteria. Fine and Gray competing risks regression was used to analyze clinical outcomes and, multilevel mixed-effects ordinal logistic regression was used to compare longitudinal disease severity scores. RESULTS: In the cohort of 396 people, 39 met criteria for CAPA. Patients with CAPA were more likely than those without CAPA to have underlying pulmonary vascular disease (41% vs 21.6%, respectively; P = .01), liver disease (35.9% vs 18.2%; P = .02), coagulopathy (51.3% vs 33.1%; P = .03), solid tumors (25.6% vs 10.9%; P = .02), multiple myeloma (5.1% vs 0.3%; P = .03), and corticosteroid exposure during the index admission (66.7% vs 42.6%; P = .005), and had lower body mass indexes (median, 26.6 vs 29.9 [calculated as weight in kilograms divided by height in meters squared]; P = .04). Patients with CAPA had worse outcomes, as measured by ordinal severity of disease scores, requiring longer time to improvement (adjusted odds ratio, 1.081.091.1; P < .001), and advancing in severity almost twice as quickly (subhazard ratio, 1.31.82.5; P < .001). They were intubated twice as long as those without CAPA (subhazard ratio, 0.40.50.6; P < .001) and had longer hospital stays (median [interquartile range], 41.1 [20.5-72.4) vs 18.5 [10.7-31.8] days; P < .001). CONCLUSION: CAPA is associated with poor outcomes. Attention to preventive measures (screening and/or prophylaxis) is warranted in people with high risk of CAPA.

The Digital Classroom: How to Leverage Social Media for Infectious Diseases Education.

Social media (SoMe) platforms have been increasingly used by infectious diseases (ID) learners and educators in recent years. This trend has only accelerated with the changes brought to our educational spaces by the coronavirus disease 2019 pandemic. Given the increasingly diverse SoMe landscape, educators may find themselves struggling with how to effectively use these tools. In this Viewpoint we describe how to use SoMe platforms (e.g., Twitter, podcasts, and open-access online content portals) in medical education, highlight medical education theories supporting their use, and discuss how educators can engage with these learning tools effectively. We focus on how these platforms harness key principles of adult learning and provide a guide for educators in the effective use of SoMe tools in educating ID learners. Finally, we suggest how to effectively interact with and leverage these increasingly important digital platforms.

New Strategies in Clinical Guideline Delivery: Randomized Trial of Online, Interactive Decision Support Versus Guidelines for Human Immunodeficiency Virus Treatment Selection by Trainees.

BACKGROUND: Support for clinicians in human immunodeficiency virus (HIV) medicine is critical given national HIV-provider shortages. The US Department of Health and Human Services (DHHS) guidelines are comprehensive but complex to apply for antiretroviral therapy (ART) selection. Human immunodeficiency virus antiretroviral selection support and interactive search tool (HIV-ASSIST) (www.hivassist.com) is a free tool providing ART decision support that could augment implementation of clinical practice guidelines. METHODS: We conducted a randomized study of medical trainees at Johns Hopkins University, in which participants were asked to select an ART regimen for 10 HIV case scenarios through an electronic survey. Participants were randomized to receive either DHHS guidelines alone, or DHHS guidelines and HIV-ASSIST to support their decision making. ART selections were graded "appropriate" if consistent with DHHS guidelines, or concordant with regimens selected by HIV experts at 4 academic institutions. RESULTS: Among 118 trainees, participants randomized to receive HIV-ASSIST had a significantly higher percentage of appropriate ART selections compared to those receiving DHHS guidelines alone (percentage of appropriate responses in DHHS vs HIV-ASSIST arms: median [Q1, Q3], 40% [30%, 50%] vs 90% [80%, 100%]; P < .001). The effect was seen for all case types, but most pronounced for complex cases involving ART-experienced patients with ongoing viremia (DHHS vs HIV-ASSIST: median [Q1, Q3], 0% [0%, 33%] vs 100% [66%, 100%]). CONCLUSIONS: Trainees using HIV-ASSIST were significantly more likely to choose appropriate ART regimens compared to those using guidelines alone. Interactive decision support tools may be important to ensure appropriate implementation of HIV guidelines. CLINICAL TRIALS REGISTRATION: NCT04080765.

Morning report for all: a qualitative study of disseminating case conferences via podcasting.

BACKGROUND: Despite its long-established importance, diagnostic reasoning (DR) education has suffered uneven implementation in medical education. The Clinical Problem Solvers (CPSolvers) podcast has emerged as a novel strategy to help teach DR through case conferences with expert diagnosticians and trainees. CPSolvers has 25,000 listeners in 147 countries. The aim of this study was to evaluate the podcast by eliciting the developers' goals of the podcast, then determining to what extent they aligned with the listeners' actual usage habits, features they valued, and perceptions of the podcast. METHODS: We conducted semi-structured interviews with 3 developers and 8 listeners from April-May 2020, followed by qualitative thematic analysis. RESULTS: Three major developer goals with sub-goals resulted: 1. To teach diagnostic reasoning in a case-based format by (1a) teaching schemas, (1b) modeling expert diagnostic reasoning, (1c) teaching clinical knowledge, and (1d) teaching diagnostic reasoning terminology. 2. To change the culture of medicine by (2a) promoting diversity, (2b) modeling humility and promoting psychological safety, and (2c) creating a fun, casual way to learn. 3. To democratize the teaching of diagnostic reasoning by leveraging technology. Listeners' usage habits, valued features, and perceptions overall strongly aligned with all these aspects, except for (1c) clinical knowledge, and (1d) diagnostic reasoning terminology. Listeners identified (1a) schemas, and (2c) promotion of psychological safety as the most valuable features of the podcast. CONCLUSION: CPSolvers has been perceived as a highly effective and novel way to disseminate DR education in the form of case conferences, serving as an alternative to traditional in-person case conferences suspended during COVID-19. CPSolvers combines many known benefits of in-person case conferences with a compassionate and entertaining teaching style, plus advantages of the podcasting medium - democratizing morning report for listeners around the world.

Reduced Mortality of Staphylococcus aureus Bacteremia in a Retrospective Cohort Study of 2139 Patients: 2007-2015.

BACKGROUND: Understanding the changing epidemiology of Staphylococcus aureus bacteremia, as well as the variables associated with poor outcomes, can yield insight into potential interventions. METHODS: This study was a retrospective, observational cohort study of adult patients at an academic medical center in New York City who had S. aureus bloodstream infections between 1 January 2007 and 31 December 2015. Participants were divided into 3 periods: group 1 (2007-2009), group 2 (2010-2012), and group 3 (2013-2015) for trend analysis. All clinical strains were genotyped (spa.). The main outcome was 30-day all-cause mortality. RESULTS: There were 1264 episodes of methicillin-susceptible S. aureus (MSSA) and 875 episodes of methicillin-resistant S. aureus (MRSA) bacteremia, with a rising proportion due to MSSA (55% group 1; 59% group 2; 63% group 3; P = .03.) There were no significant changes in average age, gender, Charlson score, and distribution of strain genotypes. Mortality in MRSA infection was unchanged (25% group 1; 25% group 2; 26% group 3), while mortality in MSSA infection significantly declined (18% group 1; 18% group 2; 13% group 3). The average time to antistaphylococcal therapy (AST) in MSSA infection declined during the study (3.7 days group 1; 3.5 group 2; 2.2 group 3). In multivariate analysis, AST within 7 days of initial positive MSSA culture was associated with survival. CONCLUSIONS: Mortality in MSSA bloodstream infection is declining, associated with a decrease in time to targeted therapy. These results emphasize the potential for rapid diagnostics and early optimization of treatment to impact outcomes in MSSA bacteremia.

Comparing Students' Clinical Grades to Scores on a Standardized Patient Note-Writing Task.

BACKGROUND: Few assessments capture the diagnostic impressions medical students form immediately following patient encounters. However, notes written for objective structured clinical examinations (OSCEs) allow learners to document their clinical reasoning in real time. The University of Illinois at Chicago College of Medicine (UIC-COM) has developed a rubric for scoring patient notes (PNs) in their OSCE for senior students. OBJECTIVE: To validate the UIC-COM PN Scoring Rubric as a measure of clinical reasoning by comparing PN scores from a similar exam at the Columbia University Vagelos College of Physicians and Surgeons (VP&S) to clinical rotation performance. DESIGN: Cross-sectional analysis. PARTICIPANTS: From a total of 146 third-year medical students who completed the OSCE at VP&S in spring 2017, we selected 60 at random, 20 from each tertile of clinical rotation performance. MAIN MEASURES: We scored these students' PNs using the rubric's four sections-Documentation, Differential Diagnosis, Justification, and Workup, each scored from 1 to 4-and calculated a composite score (maximum 100). We used one-way ANOVA to examine differences in scores between clinical rotation performance tertiles. KEY RESULTS: Students in the bottom, middle, and top clinical rotation performance tertiles had mean Documentation scores of 2.54, 2.63, and 2.88, respectively (p = 0.02, bottom vs. top tertile). Mean composite scores were 61.98, 64.05, and 67.86, respectively (p = 0.02, bottom vs. top tertile). CONCLUSIONS: We showed an association between PN scores and clinical rotation performance. Since clinical rotation grades incorporate multiple types of assessments of students' clinical reasoning skills, we believe that this correlation lends validity evidence to using the note-writing task as a measure of clinical reasoning. Future directions include expanding the task to different stages of learners, to real life patient encounters, and to formative rather than summative assessments of note-writing skills.

Picture of a pandemic: visual aids in the COVID-19 crisis.

As a global crisis, COVID-19 has underscored the challenge of disseminating evidence-based public health recommendations amidst a rapidly evolving, often uncensored information ecosystem-one fueled in part by an unprecedented degree of connected afforded through social media. In this piece, we explore an underdiscussed intersection between the visual arts and public health, focusing on the use of validated infographics and other forms of visual communication to rapidly disseminate accurate public health information during the COVID-19 pandemic. We illustrate our arguments through our own experience in creating a validated infographic for patients, now disseminated through social media and other outlets across the world in nearly 20 translations. Visual communication offers a creative and practical medium to bridge critical health literacy gaps, empower diverse patient communities through evidence-based information and facilitate public health advocacy during this pandemic and the 'new normal' that lies ahead.

Cryptococcal infection in haematologic malignancies and haematopoietic stem cell transplantation.

This review summarises both the recent and relevant studies about cryptococcal infections in haematologic malignancies and haematopoietic stem cell transplantation. Although uncommon in this patient population, this infection carries a high mortality, especially if left untreated. Given the limited data, we draw some conclusions with respect to management from the solid organ transplantation and HIV-infected literature. Herein, we discuss cryptococcosis with a particular attention to its background, epidemiology, risk factors, clinical presentation, diagnosis, treatment and prevention in this group.

Advanced age dissociates dual functions of the perirhinal cortex.

The perirhinal cortex (PRC) is proposed to both represent high-order sensory information and maintain those representations across delays. These cognitive processes are required for recognition memory, which declines during normal aging. Whether or not advanced age affects the ability of PRC principal cells to support these dual roles, however, is not known. The current experiment recorded PRC neurons as young and aged rats traversed a track. When objects were placed on the track, a subset of the neurons became active at discrete locations adjacent to objects. Importantly, the aged rats had a lower proportion of neurons that were activated by objects. Once PRC activity patterns in the presence of objects were established, however, both age groups maintained these representations across delays up to 2 h. These data support the hypothesis that age-associated deficits in stimulus recognition arise from impairments in high-order stimulus representation rather than difficulty in sustaining stable activity patterns over time.

Global impact of a virtual neurology morning report.

The global shortage and inequitable distribution of neurologists has led to significant gaps not only in neurology care, but also in neurology education. In order to increase access to neurology education, we developed neurology virtual morning report (NVMR), a virtual, open-access, case-based clinical reasoning conference available to learners worldwide. To evaluate NVMR's impact on participants' perception of, interest in, and confidence in neurology, we conducted a survey. Respondents represented 25 different countries of various income levels. The majority of respondents reported that NVMR decreased their perception of difficulty in understanding neurology and increased confidence in various clinical reasoning domains in neurology. Additionally, the majority of medical student participants showed an increased interest in pursuing neurology as a future specialty after participating in NVMR. NVMR represents a potential model for virtual educational conferences and highlights the opportunities digital education has to improve equitable access to neurology education.
