RESUMO

BACKGROUND: Invasive fungal infections have been described throughout the COVID-19 pandemic. Cryptococcal disease after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been reported in several isolated case reports and 1 larger case series. We sought to describe cryptococcal infections following SARS-CoV-2 through establishing a database to investigate underlying risk factors, disease manifestations, and outcomes. METHODS: We created a crowdsourced call for cases solicited through the Mycoses Study Group Education and Research Consortium, the Centers for Disease Control and Prevention Emerging Infectious Diseases Network, and infectious diseases Twitter groups. Data were collected in a web-based and secure REDCap survey without personal identifiers. RESULTS: Sixty-nine cases were identified and submitted by 29 separate institutional sites. Cryptococcosis was diagnosed a median of 22 days (interquartile range, 9-42 days) after SARS-CoV-2 infection. Mortality among those with available follow-up was 72% (26/36) for the immunocompetent group and 48% (15/31) for the immunocompromised group (likelihood ratio, 4.01; P = .045). We observed a correlation between disease manifestation (central nervous system infection, proven/probable disseminated disease, and respiratory) and mortality (P = .002). CONCLUSIONS: The mortality rate of 59% for patients with cryptococcosis following SARS-CoV-2 is higher than that of modern Cryptococcus cohorts. There was an association between immunocompromised status and cryptococcal disease manifestations as well as mortality. Moreover, our series emphasizes the need for clinical and laboratory assessment of opportunistic infections beyond 30 days when concerning symptoms develop.

RESUMO

Invasive fungal infections cause significant morbidity and mortality in hematopoietic stem cell transplant recipients. In order to minimize these infections, prophylaxis has become routine, although the agents used have changed over time. This presents new challenges as we consider an approach to breakthrough infections and recognize the epidemiologic shift toward isolates with higher rates of drug resistance. This review outlines the management of the most common pathogens (Candida, Aspergillus, Mucorales) as well as rarer pathogens that have higher rates of resistance (Trichosporon, Fusarium, Scedosporium, and Lomentospora). We discuss potential approaches to proven or possible breakthrough infections with yeast and pulmonary mold disease. Finally, we outline the role for combination therapy and newer antifungals, acknowledging current knowledge gaps and areas for future exploration.

RESUMO

In 2022, the largest global outbreak of mpox to date emerged. In the immunocompetent host, mpox generally presents as a self-limiting illness. However, immunosuppression, such as that seen with advanced HIV, has been associated with significant morbidity and mortality related to mpox infection. To evaluate the impact of immunosuppression related to solid organ transplantation on clinical features and outcomes of mpox we established a multicenter case registry. Eleven cases from 7 participating centers in the USA were submitted. All cases occurred in males. The majority were kidney transplant recipients (91%, n = 10). Median duration of symptoms at presentation was 6 days (range, 3-14 days). Rates of hospitalization were high (73%, n = 8) with a median length of stay of 4.5 days (range, 1-10 days). Mpox in solid organ transplant recipients was associated with a high burden of skin lesions and systemic symptoms. Fever, fatigue, pharyngitis, and proctitis were commonly reported. Other clinical features included headache, myalgia, epididymo-orchitis, urinary retention, hematemesis, pneumonitis, and circulatory shock. All patients received treatment with tecovirimat. There was 1 mpox-related death in the cohort. Infection was reported to have resolved at 30-day follow-up in all other cases.

RESUMO

There is a need for formal students-as-teachers education with authentic application. We report on a course that teaches and models effective educational theory. Students applied theory by writing questions with answer explanations which were incorporated into an online educational platform used by first-year medical students.

RESUMO

Xenotransplantation of organs from swine in immunosuppressed human recipients poses many of the same challenges of allotransplantation relative to the risk for infection, malignancy, or graft rejection in proportion to the degree of immunosuppression and epidemiologic exposures. The unique features of xenotransplantation from pigs relative to infectious risk center on the potential for unusual organisms derived from swine causing productive infection, "xenosis" or "xenozoonosis," in the host. Based on experience in allotransplantation, the greatest hazard is due to viruses, due to the relative lack of information regarding the behavior of these potential pathogens in humans, the absence of validated serologic and molecular assays for swine-derived pathogens, and uncertainty regarding the efficacy of therapeutic agents for these organisms. Other known, potential pathogens (i.e., bacteria, fungi, parasites) tend to be comparable to those of humans. Concerns remain for unknown organisms in swine that may replicate in immunosuppressed humans. Clinical trials of genetically modified organs sourced from swine in immunosuppressed humans with organ failure are under development. Such trials require informed consent regarding potential infectious risks to the recipient, determination of breeding characteristics of swine, assessments of potential risks to the public and healthcare providers, consideration of ethical issues posed by this novel therapy, and defined strategies to monitor and address infectious episodes that may be encountered by healthcare teams. Clinical trials in xenotransplantation will allow improved definition of potential infectious risks.

RESUMO

Background: Microbiology is a critical and expansive topic that many medical schools' curriculum must teach in a constrained time frame. We implemented a microbiology question bank smart phone app enhanced with game elements and clinical pearls during a microbiology course for first-year medical students. We hypothesized that these enhancements and clinical pearls would engage the students meaningfully and increase their knowledge base. Methods: Though use was optional, students' game play was recorded through the app, which was compared to test grades retrospectively. A player efficiency rating (PER) was calculated as a function of question response, accuracy, and engagement. Students were separated into tertiles of PER and median exam grades were compared using a non-parametric Kruskal-Wallis (KW) test. An anonymous satisfaction and usability feedback survey was also administered. Results: One hundred eighty-one of the 189 students (96%) answered at least one question, and 165 (87%) completed all 56 questions. The average PER was 84.75. We received feedback surveys from 61 (34%) students in the course, with positive responses regarding the perceived impact on learning microbiology. The KW test found a positive correlation for median exam scores of the player groups when divided into tertiles by PER (p = 0.0002). Conclusions: We leveraged gamification and clinical pearls to design a supplemental microbiology question bank. We found high engagement overall and higher class exam scores associated with greater use of the question bank.

RESUMO

Leveraging elements of game design and theories of human motivation, gamification provides a variety of techniques to engage learners in novel ways. Our Clinical and Translational Science Award created the software platform (Kaizen-Education©) to deliver gamified educational content in 2012. Here, we explore two novel use cases of this platform to provide practical insights for leveraging these methods in educational settings: (1) national training in rigor, reproducibility, and transparency and (2) attainment of learner competency (n = 7) as a gauge of curricular effectiveness across Master of Public Health degree tracks (n = 5). Data were captured in real time during player interaction with Kaizen-Education© to provide descriptive analyses of player engagement in both implementation examples. We then assessed item analysis to assess knowledge gain and competency attainment. We have just begun to leverage the potential for gamification to engage learners, enhance knowledge acquisition, and document completion of training, across various learning environments. We encourage a systematic approach to gamification applying insights from self-determination theory to learners and learning environments, a methodical approach to game design and rigorous analysis after implementation to generate evidence-based insights to maximize educational return for time invested.

RESUMO

We describe the impact of universal masking and universal testing at admission on high-risk exposures to severe acute respiratory syndrome coronavirus 2 for healthcare workers. Universal masking decreased the rate of high-risk exposures per patient-day by 68%, and universal testing further decreased those exposures by 77%.

RESUMO

BACKGROUND: Continuity between patients and physicians is a core principle of primary care and an accreditation requirement. Resident continuity clinics face challenges in nurturing continuity for their patients and trainees. OBJECTIVE: We undertook a scoping review of the literature to better understand published benchmarks for resident continuity; the effectiveness of interventions to improve continuity; and the impact of continuity on resident and patient satisfaction, patient outcomes, and resident career choice. METHODS: We developed a MEDLINE search strategy to identify articles that defined continuity in residency programs in internal medicine, family medicine, and pediatrics published prior to December 31, 2015, and used a quality evaluation tool to assess included studies. RESULTS: The review includes 34 articles describing 12 different measures of continuity. The usual provider of care and continuity for physician formulas were most commonly utilized, and mean baseline continuity was 56 and 55, respectively (out of a total possible score of 100). Clinic and residency program redesign innovations (eg, advanced access scheduling, team-based care, and block scheduling) were studied and had mixed impact on continuity. Continuity in resident clinics is lower than published continuity rates for independently practicing physicians. CONCLUSIONS: Interventions to enhance continuity in resident clinics have mixed effects. More research is needed to understand how changes in continuity affect resident and patient satisfaction, patient outcomes, and resident career choice. A major challenge to research in this area is the lack of empanelment of residents' patients, creating difficulties in scheduling and measuring continuity visits.
