Developing a Novel Case-Based Gastroenterology/Hepatology Online Resource for Enhanced Education During and After the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic reshaped the delivery of medical education, necessitating novel modes of instruction to facilitate distance learning. Online medical education resources provide opportunities for self-directed and asynchronous learning. GISIM is a free, open access educational website dedicated to gastroenterology (GI)/hepatology, which teaches pathophysiology and disease management, and supports clinical reasoning skill development through interactive, dynamic, case presentation-based journeys. AIMS: (1) To describe the creation of a mobile-optimized, GI/hepatology educational resource for medical trainees, and (2) to report on trainee feedback on completing and authoring GISIM cases. METHODS: GISIM was created on WordPress and modeled after NephSIM, an e-learning platform dedicated to Nephrology. Content was developed by internal medicine residents and GI/hepatology fellows and attendings. Cases are interactive, prompting users to select differential diagnoses and management plans, with immediate feedback provided on response. Self-reported user demographics and website feedback were collected with an embedded survey. A separate survey evaluated case authors' experiences. RESULTS: GISIM launched in February 2021 and received 12,184 website views and 2003 unique visitors between February 1 2021 and February 28 2022. New cases are disseminated bimonthly. Sixty-one user surveys were collected, with a majority completed by fellows (38%) and residents (26%). All users found the website easy to use and most reported enhanced understanding of case topic areas. Nine author surveys were collected. Authors reported significant learning on chosen topics and improved clinical knowledge through their participation. CONCLUSIONS: We developed a novel GI/hepatology case-based resource that enables distance learning and was perceived as a valuable educational tool by users and authors.

Creating ophthalmology experiences in undergraduate medical education: pilot of a cased-based learning ophthalmology tool.

PURPOSE: To evaluate medical student perceptions of a novel ophthalmology resource delivered through facilitated workshops in the core clerkship curriculum. METHODS: We created www.2020sim.com, a free case-based learning (CBL) ophthalmology tool, adapted from NephSIM (www.nephsim.com). The tool was first piloted with the internal medicine (IM) residents. After confirming a need, we focused on undergraduate medical education (UME) by expanding the 20/20 SIM content and partnering with the neurology (pilot academic year [AY] 2020-2021) and pediatric clerkships (pilot AY 2021-2022) to deliver a facilitated one-hour ophthalmology workshop within each clerkship's didactic curriculum. We evaluated the tool using pre- and post-surveys and knowledge assessments. RESULTS: Of 80 IM residents, 33 (41.3%) completed the needs assessment. Of the 25 residents who attended the workshop, 23 (92.0%) completed the exit survey. IM residents reported discomfort in several ophthalmology domains (9 of 14 rated mean score < 3.0), confirming a need. Most (n = 21/23, 91.3%) rated the tool as good/excellent. Of 145 neurology clerkship students, 125 (86.2%) and at least 88 (60.7%) students completed the pre- and post-test/exit surveys, respectively. On average, participants highly rated the tool, perceiving 20/20 SIM to be relevant to their education [4.1 (0.8)]. Mean pre- to post-test knowledge scores increased from 7.5 to 8.5/10.0 points (p < 0.001). Of the 136 pediatric clerkship students, 67 (49.3%) and 51 (37.5%) completed the pre- and post-surveys, respectively. Respondents perceived increased comfort with ophthalmology topics after the facilitated workshop [3.8 (0.8)]. Mean pre- to post-test knowledge scores trended from 1.8 to 2.0/5.0 points (p = 0.30). Collectively, 20/139 (14.4%) of exit survey respondents visited www.2020sim.com within 1 month after the workshop. CONCLUSION: After identifying areas of greatest need with residents, we partnered with core clerkships to deliver cross-disciplinary ophthalmology content in UME. We found high engagement with 20/20 SIM, with trends toward increased knowledge.

Influence of patient characteristics and immunosuppressant management on mortality in kidney transplant recipients hospitalized with coronavirus disease 2019 (COVID-19).

The influence of patient characteristics and immunosuppression management on COVID-19 outcomes in kidney transplant recipients (KTRs) remains uncertain. We performed a single-center, retrospective review of all adult KTRs admitted to the hospital with confirmed COVID-19 between 03/15/2020 and 05/15/2020. Patients were followed from the date of admission up to 1 month following hospital discharge or study conclusion (06/15/2020). Baseline characteristics, laboratory parameters, and immunosuppression were compared between survivors and patients who died to identify predictors of mortality. 38 KTRs with a mean baseline eGFR of 52.5 ml/min/1.73 m2 were hospitalized during the review period. Maintenance immunosuppression included tacrolimus (84.2%), mycophenolate (89.5%), and corticosteroids (81.6%) in the majority of patients. Eleven patients (28.9%) died during the hospitalization. Older age (OR = 2.05; 1.04-4.04), peak D-dimer (OR = 1.20; 1.04-1.39), and peak white blood cell count (OR = 1.11; 1.02-1.21) were all associated with mortality among KTRs hospitalized for COVID-19. Increased mortality was also observed among KTRs with concomitant HIV infection (87.5% vs. 36.1%; p < .01). Conversely, immunosuppression intensity and degree of reduction following COVID-19 diagnosis were not associated with either survival or acute allograft rejection. Our findings potentially support a strategy of individualization of immunosuppression targets based on patient-specific risk factors, rather than universal immunosuppression reduction for KTRs at risk from COVID-19.

Back off baclofen when the kidneys don't work.

Medication adverse events are common and often preventable. Patients with diminished kidney function are particularly susceptible to adverse events, especially if the medication's primary means of elimination is through the kidneys. Neurotoxicity from baclofen (80% excreted by the kidneys) is increasingly being recognized in patients with diminished kidney function. Chauvin et al. performed a large population-based retrospective cohort study in patients with end-stage kidney disease (ESKD) and showed a high rate of encephalopathy with hospitalizations shortly after baclofen exposure. This commentary discusses the high rate of altered mental status after baclofen exposure in patients with ESKD, potential reasons for the continued reports of this adverse event, and strategies to educate the health care community.

COVID-19 and kidney transplantation: Results from the TANGO International Transplant Consortium.

Kidney transplant recipients may be at a high risk of developing critical coronavirus disease 2019 (COVID-19) illness due to chronic immunosuppression and comorbidities. We identified hospitalized adult kidney transplant recipients at 12 transplant centers in the United States, Italy, and Spain who tested positive for COVID-19. Clinical presentation, laboratory values, immunosuppression, and treatment strategies were reviewed, and predictors of poor clinical outcomes were determined through multivariable analyses. Among 9845 kidney transplant recipients across centers, 144 were hospitalized due to COVID-19 during the 9-week study period. Of the 144 patients, 66% were male with a mean age of 60 (±12) years, and 40% were Hispanic and 25% were African American. Prevalent comorbidities included hypertension (95%), diabetes (52%), obesity (49%), and heart (28%) and lung (19%) disease. Therapeutic management included antimetabolite withdrawal (68%), calcineurin inhibitor withdrawal (23%), hydroxychloroquine (71%), antibiotics (74%), tocilizumab (13%), and antivirals (14%). During a median follow-up period of 52 days (IQR: 16-66 days), acute kidney injury occurred in 52% cases, with respiratory failure requiring intubation in 29%, and the mortality rate was 32%. The 46 patients who died were older, had lower lymphocyte counts and estimated glomerular filtration rate levels, and had higher serum lactate dehydrogenase, procalcitonin, and interleukin-6 levels. In sum, hospitalized kidney transplant recipients with COVID-19 have higher rates of acute kidney injury and mortality.

Kidney transplantation using lymphocyte depleting induction and standard maintenance immunosuppression at the height of the SARS-CoV-2 pandemic in New York City: A single-center experience.

BACKGROUND: Concerns have been raised regarding proceeding with kidney transplantation using standard immunosuppression in COVID-19 endemic areas. METHODS: We performed a single-center review of all adult kidney transplants performed during the COVID-19 pandemic in New York City. Patients were managed with standard immunosuppression protocols, including lymphocyte depleting induction and trough-guided tacrolimus. Retrospective data were collected for 3 months from the date of transplantation or until study conclusion (5/7/2020). The primary outcomes assessed included patient and allograft survival as well as COVID-19 related hospital readmission. RESULTS: 30 kidney transplants were performed during the height of the COVID-19 pandemic. After a median follow-up of 51.5 days, 93.3% of patients were alive with 100% death-censored allograft survival. 9 patients were readmitted to the hospital during the study period, 4 (13.3%) related to infection with COVID-19. Infections were mild in 3/4 patients, with one patient developing severe disease leading to respiratory failure. Patients readmitted with COVID-19 were numerically more likely to be African American, have a BMI > 30 kg/m2, have a lymphocyte count ≤ 300 cells/mL, and be on maintenance corticosteroids. CONCLUSIONS: Kidney transplantation in areas endemic to COVID-19 using standard induction and maintenance immunosuppression appears to be associated with a modest risk for severe COVID-19 related disease.

Implementation of a quality improvement strategy to increase outpatient kidney transplant referrals.

BACKGROUND: Kidney transplantation remains the optimal therapy for patients with end stage kidney disease (ESKD), though a small fraction of patients on dialysis are on organ waitlists. An important barrier to both preemptive kidney transplantation and successful waitlisting is timely referral to a kidney transplant center. We implemented a quality improvement strategy to improve outpatient kidney transplant referrals in a single center academic outpatient nephrology clinic. METHODS: Over a 3 month period (July 1-September 30, 2016), we assessed the baseline kidney transplantation referral rate at our outpatient nephrology clinic for patients 18-75 years old with an estimated glomerular filtration rate (eGFR) of less than 20 mL/min/1.73m2 (2 values over 90 days apart). Charts were manually reviewed by two reviewers to look for kidney transplant referrals and documentation of discussions about kidney transplantation. We then performed a root cause analysis to explore potential barriers to kidney transplantation. Our intervention began on July 1, 2017 and included the implementation of a column in the electronic medical record (EMR) which displayed the patient's last eGFR as part of the clinic schedule. In addition, physicians were given a document listing their patients to be seen that day with an eGFR of < 20 mL/min/1.73m2. Annual education sessions were also held to discuss the importance of timely kidney transplant referral. RESULTS: At baseline, 54 unique patients with eGFR ≤20 ml/min/1.73 m2 were identified who were seen in the Clinic between July 1, 2016 and September 30, 2016. 29.6% (16) eligible patients were referred for kidney transplantation evaluation. 69.5% (37) of these patients were not referred for kidney transplant evaluation. 46.3% (25) did not have documentation regarding kidney transplant in the EMR. nephrologist's most recent note. Following the intervention, 66 unique patients met criteria for eligibility for kidney transplant evaluation. Kidney transplant referrals increased to 60.6% (p <  0.001). CONCLUSIONS: Our pilot implementation study of a strategy to improve outpatient kidney transplant referrals showed that a free, simple, scalable intervention can significantly improve kidney transplant referrals in the outpatient setting. This intervention targeted the nephrologist's role in the transplant referral, and facilitated the process of patient recognition and performing the referral itself without significantly interrupting the workflow. Next steps include further investigation to study the impact of early referral to kidney transplant centers on preemptive and living donor kidney transplantation as well as successful waitlisting.

Tackling acid-base disorders, one Twitter poll at a time.

Understanding and interpretation of acid-base disorders is an important clinical skill that is applicable to the majority of physicians. Although this topic is taught early in medical school, acid-base disturbances have been described as challenging by postgraduate trainees. We describe the use of Twitter, an online microblogging platform, to augment education in acid-base disturbances by using polls in which the user is shown laboratory values and then asked to select the most likely etiology of the disorder. The answer and a brief explanation are then shared in a subsequent tweet. Both polling questions and answers are shared from the account for the online, mobile-optimized, nephrology teaching tool NephSIM (https://www.nephsim.com/). An anonymous survey was administered to assess attitudes toward these polls. Using Twitter as an approach to enhance teaching of acid-base disturbances was both feasible and an engaging way to teach a challenging topic for trainees and physicians. Moreover, the coronavirus disease 2019 (COVID-19) pandemic has demonstrated the importance of incorporating virtual learning opportunities in all levels of medical education.

Severe hypercalcemia preceding a diagnosis of Pneumocystis jirovecii pneumonia in a liver transplant recipient.

BACKGROUND: Incidence of the opportunistic infection Pneumocystis jirovecii pneumonia (PJP) in solid organ transplant patients ranges from 5 to 15% with a mortality of up to 38%. CASE PRESENTATION: We present a liver transplant recipient who developed hypoxemic respiratory failure related to PJP soon after treatment for allograft rejection. His presentation was preceded by severe hypercalcemia of 14.6 mg/dL and an ionized calcium of 1.7 mmol/L which remained elevated despite usual medical management and eventually required renal replacement therapy. As approximately 5% of PJP cases have granulomas, here we review the role of pulmonary macrophages and inflammatory cytokines in the pathophysiology of granuloma-mediated hypercalcemia. We also discuss the interpretation of our patient's laboratory studies, response to medical therapy, and clinical risk factors which predisposed him to PJP. CONCLUSIONS: It is important for clinicians to consider PJP as an etiology of granulomatous pneumonia and non-parathyroid hormone mediated hypercalcemia in chronically immunosuppressed organ transplant recipients for timely diagnosis and management.

Salt and Water: A Review of Hypernatremia.

Serum sodium disorders are generally a marker of water balance in the body. Thus, hypernatremia is most often caused by an overall deficit of total body water. Other unique circumstances may lead to excess salt, without an impact on the body's total water volume. Hypernatremia is commonly acquired in both the hospital and community. As hypernatremia is associated with increased morbidity and mortality, treatment should be initiated promptly. In this review, we will discuss the pathophysiology and management of the main types of hypernatremia, which can be categorized as either a loss of water or gain of sodium that can be mediated by renal or extrarenal mechanisms.

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.

Reimagining Nephrology Fellowship Education to Meet the Future Needs of Nephrology: A Report of the American Society of Nephrology Task Force on the Future of Nephrology.

The American Society of Nephrology (ASN) Task Force on the Future of Nephrology was established in April 2022 in response to requests from the American Board of Internal Medicine and the Accreditation Council for Graduate Medical Education regarding training requirements in nephrology. Given recent changes in kidney care, ASN also charged the task force with reconsidering all aspects of the specialty's future to ensure that nephrologists are prepared to provide high-quality care for people with kidney diseases. The task force engaged multiple stakeholders to develop 10 recommendations focused on strategies needed to promote: ( 1 ) just, equitable, and high-quality care for people living with kidney diseases; ( 2 ) the value of nephrology as a specialty to nephrologists, the future nephrology workforce, the health care system, the public, and government; and ( 3 ) innovation and personalization of nephrology education across the scope of medical training. This report reviews the process, rationale, and details (the "why" and the "what") of these recommendations. In the future, ASN will summarize the "how" of implementing the final report and its 10 recommendations.

Urine Microscopy for Internal Medicine Residents: A Needs Assessment and Implementation of Virtual Teaching Sessions.

Background: Although urine microscopy is an important step in the initial evaluation of a patient with kidney disease, internal medicine residents have minimal exposure to this technique during their training. The goal of this study was to understand knowledge of and attitudes toward urine microscopy among internal medicine residents and to implement virtual urine microscopy teaching sessions. Methods: A voluntary, anonymous, online survey was sent to all of the categorical internal medicine residents (n=131) training at the Icahn School of Medicine at Mount Sinai (ISMMS). The survey included 13 questions to assess attitudes toward, experience with, and clinical interpretation of urine microscopy specimens. In response to the survey results, we implemented virtual urine microscopy teaching sessions using video conferencing software that incorporated real-time urine sediment analysis with nephrology fellows and attending nephrologists. Results: The survey response rate was 45% (59 of 131). Forty-seven percent (28 of 59) of respondents reported performing urine microscopy at least once during their training, and 75% (44 of 59) of respondents did not feel comfortable performing urine microscopy. The majority of residents (92%; 54 of 59) reported they felt urine microscopy was very helpful or somewhat helpful in the evaluation of patients with AKI. Overall, 41% of responses to clinical interpretation questions were considered correct. Following survey completion, virtual urine microscopy sessions were held monthly and well received by the participants. Conclusions: Our study found that internal medicine residents perceive urine microscopy as a helpful diagnostic tool, although lack the skills to perform and interpret urine microscopy sediments. Virtual educational sessions using video conferencing software are a technically feasible approach to teaching urine microscopy to internal medicine residents. Future studies include a study of the effect of these sessions on learning of urine microscopy.

Busting myths in online education: Faculty examples from the field.

The shift in learning environments due to the COVID-19 pandemic necessitates a closer look at course design, faculty approaches to teaching, and student interaction, all of which may predict learner achievement and satisfaction. Transitioning to an online environment requires the reinvention, reimagining, and applying of "e-flavors" of general learning theory. With this shift to online learning comes the opportunity for misunderstandings and "myths" to occur, which may stand in the way of faculty embracing online learning and fully realizing its potential. This article seeks to address several myths and misconceptions that have arisen in higher education during the rapid shift to online teaching and learning. While not comprehensive, these myths represent a snapshot of common challenges. These are we can transfer our in-person course design to online; adult learners do not need an empathetic approach; and online teaching and learning is socially isolating. Through an appreciative inquiry framework, we present each myth in the context of relevant literature and invite faculty with varied online teaching experience to share their own case studies that illustrate how they have "busted" these myths with the goal to identify existing examples of locally effective practices for the express purpose of replication that leads to positive change.

The Many Faces of Calcineurin Inhibitor Toxicity-What the FK?

Calcineurin inhibitors (CNIs) are both the savior and Achilles' heel of kidney transplantation. Although CNIs have significantly reduced rates of acute rejection, their numerous toxicities can plague kidney transplant recipients. By 10 years, virtually all allografts will have evidence of CNI nephrotoxicity. CNIs have been strongly associated with hypertension, dyslipidemia, and new onset of diabetes after transplantation-significantly contributing to cardiovascular risk in the kidney transplant recipient. Multiple electrolyte derangements including hyperkalemia, hypomagnesemia, hypercalciuria, metabolic acidosis, and hyperuricemia may be challenging to manage for the clinician. Finally, CNI-associated tremor, gingival hyperplasia, and defects in hair growth can have a significant impact on the transplant recipient's quality of life. In this review, the authors briefly discuss the pharmacokinetics of CNI and discuss the numerous clinically relevant toxicities of commonly used CNIs, cyclosporine and tacrolimus.

Training the Public Physician: The Nephrology Social Media Collective Internship.

The significant growth of social media use by the medical community, including nephrology, has led to a need to equip health care professionals with the mentorship, knowledge, and tools to use these platforms both effectively and professionally. Social media is free and accessible to almost anyone with a computer or mobile device, which not only has revolutionized the dissemination of information, but also has created a venue for unprofessionalism and missteps. This article describes the Nephrology Social Media Collective internship, a 12-month, mentored training program during which selected interns participate in a curriculum of lectures, activities, and projects that aim to increase their knowledge, proficiency, and confidence in the use of social media. The goal of the internship is to train participants to acquire modern communication skills that are not taught in traditional medical training, and leverage these to become leaders in medicine. The structure of the internship, application process, and educational components, along with areas for improvement and future directions, are discussed.

COVID-19 and the kidney: what we think we know so far and what we don't.

The novel coronavirus disease infection (COVID-19) outbreak that was declared a global pandemic in March 2020 had led to an internationally variable but concerning incidence of COVID-associated acute kidney injury (AKI), with prevalence reported as high as 46% in large cohorts of hospitalized patients. Variability in AKI may be explained by differences in traditional risk factors for AKI, heterogeneity among patient cohorts, and differences in racial and ethnic groups. Further, AKI requiring kidney replacement therapies (KRT) has been associated with increased mortality. Proposed mechanisms of kidney injury include direct viral-induced tubular or glomerular injury, sepsis-associated AKI, and thrombotic disease. Kidney pathology include acute tubular injury, glomerular fibrin thrombi, pigmented tubular casts, and collapsing focal segmental glomerulosclerosis. "Viral-like" particles have been observed in renal samples at electron microscopy and viral RNA has been identified in both glomerular and tubular compartments of kidney specimens, but the link between viral presence and injury remain unclear. Though the link between AKI and poor outcomes is clear, prevalence and outcomes of COVID-19 in patients with chronic kidney disease and end stage kidney disease has not yet been reported. In patients on immunosuppression like those with kidney transplants or glomerular disease, COVID-19 has presented a management dilemma. Herein, we review the existing literature on kidney disease in COVID-19 and discuss what remains to be learned.
