RESUMO

BACKGROUND: Pythiosis is a rare disease with high mortality, with over 94% of cases reported from Thailand and India. Prompt diagnosis and surgery improves patient outcomes. Therefore, continuing professional development (CPD) is essential for early recognition. However, a needs assessment related to a pythiosis CPD program has not been performed. OBJECTIVES: We conducted a needs assessment to develop a pythiosis CPD program. PATIENTS/METHODS: We conducted a survey study with 267 King Chulalongkorn Memorial Hospital residents (141 internal medicine (IM) residents and 126 surgery residents). A 30-item survey consisting of a knowledge assessment, demographic section, and an attitudes portion was distributed both electronically and via paper. The data was analyzed with descriptive and inferential statistics. RESULTS: Sixty-seven percent completed the survey (110/141 IM residents, 70/126 surgery residents). The mean score [95% confidence interval] on the knowledge assessment was 41.67% [39.64%-43.69%] across all objectives. The three domains with the highest scores were pythiosis risk factors (67.22% correct), microbiologic characteristics (50.83%), and radiographic interpretation (50.56%). The three domains with the lowest scores were laboratory investigation (15.00%), epidemiology (29.17%), and symptomatology (30.83%). Most participants noted that the program should be online with both synchronous and asynchronous sessions, with a preferred length of 60-90 minutes per session. CONCLUSION: The pythiosis CPD program should emphasize education regarding symptomatology, laboratory investigation, and epidemiology, all of which are critical for the early detection of pythiosis to decrease mortality from this devastating disease. Most respondents felt this program was necessary and should be implemented in a virtual blended format.

RESUMO

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.

RESUMO

Background: Environmental fungi are threats to personal and public health. Fungal in vitro diagnostics help diagnose invasive fungal infections (IFIs), but clinicians remain underinformed about their use and interpretation. Given the increasing use of social media to share infectious diseases-related content, we designed and implemented a multisite Twitter-based curriculum focused on IFIs and related diagnostics. Methods: Questions were posted through a dedicated Twitter account twice weekly over 8 weeks. We surveyed clinicians at 3 US academic centers before and after completion of the curriculum and interviewed a subset of participants. We undertook quantitative and qualitative evaluations and reviewed Twitter analytics. Results: We surveyed 450 participants. One hundred twenty-one participants (27%) completed the knowledge assessment precurriculum, 68 (15%) postcurriculum, and 53 (12%) pre- and postcurriculum. We found a significant increase (72% vs 80%, P = .005) in the percentage of correct answers in the pre- versus postcurriculum knowledge assessments. Perceived benefits included a well-executed curriculum that facilitated engagement with appropriately detailed tweetorials from a dedicated Twitter account. Perceived barriers included lack of awareness of tweetorial posts and timing, competing priorities, and the coronavirus disease 2019 pandemic. The Twitter account accrued 1400 followers from 65 countries during the 8-week period. Tweets with multiple-choice questions had a median of 14 904 impressions (interquartile range [IQR], 12 818-16 963), 798 engagements (IQR, 626-1041), and an engagement rate of 6.1% (IQR, 4.2%-6.6%). Conclusions: Educators can leverage social media to share content with a large audience and improve knowledge while being mindful of the barriers associated with implementing a curriculum on social media.

RESUMO

Immunogenicity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination is diminished in hematopoietic stem cell transplant (HSCT) recipients. To summarize current evidence and identify risk factors for attenuated responses, 5 electronic databases were searched since database inceptions through 12 January 2023 for studies reporting humoral and/or cellular immunogenicity of SARS-CoV-2 vaccination in the HSCT population. Using descriptive statistics and random-effects models, extracted numbers of responders and pooled odds ratios (pORs) with 95% confidence intervals (CIs) for risk factors of negative immune responses were analyzed (PROSPERO: CRD42021277109). From 61 studies with 5906 HSCT recipients, after 1, 2, and 3 doses of messenger RNA (mRNA) SARS-CoV-2 vaccines, the mean antispike antibody seropositivity rates (95% CI) were 38% (19-62), 81% (77-84), and 80% (75-84); neutralizing antibody seropositivity rates were 52% (40-64), 71% (54-83), and 78% (61-89); and cellular immune response rates were 52% (39-64), 66% (51-79), and 72% (52-86). After 2 vaccine doses, risk factors (pOR; 95% CI) associated with antispike seronegativity were male recipients (0.63; 0.49-0.83), recent rituximab exposure (0.09; 0.03-0.21), haploidentical allografts (0.46; 0.22-0.95), <24 months from HSCT (0.25; 0.07-0.89), lymphopenia (0.18; 0.13-0.24), hypogammaglobulinemia (0.23; 0.10-0.55), concomitant chemotherapy (0.48; 0.29-0.78) and immunosuppression (0.18; 0.13-0.25). Complete remission of underlying hematologic malignancy (2.55; 1.05-6.17) and myeloablative conditioning (1.72; 1.30-2.28) compared with reduced-intensity conditioning were associated with antispike seropositivity. Ongoing immunosuppression (0.31; 0.10-0.99) was associated with poor cellular immunogenicity. In conclusion, attenuated humoral and cellular immune responses to mRNA SARS-CoV-2 vaccination are associated with several risk factors among HSCT recipients. Optimizing individualized vaccination and developing alternative COVID-19 prevention strategies are warranted.

RESUMO

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.

RESUMO

BACKGROUND: Ribavirin use for respiratory syncytial virus (RSV) infection in patients with haematologic malignancies (HM) and haematopoietic stem cell transplant (HSCT) recipients remains controversial. OBJECTIVES: To summarize the current evidence of ribavirin treatment in association with mortality and progression to lower respiratory tract infection (LRTI) among patients with HM/HSCT with RSV infection. DATA SOURCES: MEDLINE, Embase, and the Institute for Scientific Information Web of Science. STUDY ELIGIBILITY CRITERIA: Randomized controlled trials and observational studies investigating the effects of ribavirin, compared with treatment without ribavirin, for RSV infection. PARTICIPANTS: Patients with HM/HSCT. INTERVENTIONS: Ribavirin versus no ribavirin. ASSESSMENT OF RISK OF BIAS: The risk of bias in non-randomized studies of exposure (ROBIN-E). METHODS OF DATA SYNTHESIS: The random-effects model was used to calculate the pooled OR (pOR) with 95% CI for the pooled effect estimates of ribavirin benefits. Grading of recommendation assessment, development, and evaluation was used to evaluate the certainty of evidence. RESULTS: One randomized controlled trial and 14 observational studies were included, representing 1125 patients with HM/HSCT. Ribavirin use was not associated with lower all-cause or RSV-associated mortality with pORs [95% CI] of 0.81 [0.40, 1.66], I2 = 55% (low certainty of evidence) and 0.48 [0.11, 2.15], I2 = 64% (very low certainty of evidence), respectively. In subgroup analyses, ribavirin use was associated with lower mortality in patients with HM/HSCT with LRTI with pOR [95% CI] of 0.19 [0.07, 0.51], I2 = 0% (moderate certainty of evidence). In subgroup analyses among studies providing adjusted OR, ribavirin use was associated with lower all-cause mortality with pOR of 0.41 [0.23, 0.74], I2 = 0% (moderate certainty of evidence). In addition, aerosolized ribavirin was associated with lower progression to LRTI with pOR [95% CI] of 0.27 [0.09, 0.80], I2 = 71% (low certainty of evidence). CONCLUSIONS: Ribavirin may be a reasonable option to treat RSV in patients with HM/HSCT in the absence of other effective antiviral agents.

RESUMO

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.

RESUMO

Patients with multiple myeloma (MM) have a diminished immune response to coronavirus disease 2019 (COVID-19) vaccines. Risk factors for an impaired immune response are yet to be determined. We aimed to summarize the COVID-19 vaccine immunogenicity and to identify factors that influence the humoral immune response in patients with MM. Two reviewers independently conducted a literature search in MEDLINE, Embase, ISI Web of Science, Cochrane library, and Clinicaltrials.gov from existence until 24 May 24 2022. (PROSPERO: CRD42021277005). A total of 15 studies were included in the systematic review and 5 were included in the meta-analysis. The average rate (range) of positive functional T-lymphocyte response was 44.2% (34.2%-48.5%) after 2 doses of messenger RNA (mRNA) COVID-19 vaccines. The average antispike antibody response rates (range) were 42.7% (20.8%-88.5%) and 78.2% (55.8%-94.2%) after 1 and 2 doses of mRNA COVID-19 vaccines, respectively. The average neutralizing antibody response rates (range) were 25% (1 study) and 62.7% (53.3%-68.6%) after 1 and 2 doses of mRNA COVID-19 vaccines, respectively. Patients with high-risk cytogenetics or receiving anti-CD38 therapy were less likely to have a humoral immune response with pooled odds ratios of 0.36 (95% confidence interval [95% CI], 0.18, 0.69), I2 = 0% and 0.42 (95% CI, 0.22, 0.79), I2 = 14%, respectively. Patients who were not on active MM treatment were more likely to respond with pooled odds ratio of 2.42 (95% CI, 1.10, 5.33), I2 = 7%. Patients with MM had low rates of humoral and cellular immune responses to the mRNA COVID-19 vaccines. Further studies are needed to determine the optimal doses of vaccines and evaluate the use of monoclonal antibodies for pre-exposure prophylaxis in this population.

RESUMO

The ongoing 2022 multicountry outbreak of monkeypox is the largest in history to occur outside of Africa. Monkeypox is an emerging zoonotic disease that for decades has been viewed as an infectious disease with significant epidemic potential because of the increasing occurrence of human outbreaks in recent years. As public health entities work to contain the current outbreak, healthcare professionals globally are aiming to become familiar with the various clinical presentations and management of this infection. We present in this review an updated overview of monkeypox for healthcare professionals in the context of the ongoing outbreaks around the world.

RESUMO

Background: Real-world data on the effectiveness of neutralizing casirivimab-imdevimab monoclonal antibody (Cas-Imd mAb) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among high-risk patients may inform the response to future SARS-CoV-2 variants. Methods: This study covers an observational retrospective data analysis in Banner Health Care System sites, mainly in Arizona. During the study period, the prevalence of SARS-CoV-2 Delta variant was between 95% and 100%. Of 29 635 patients who tested positive for coronavirus disease 2019 (COVID-19) between 1 August 2021 and 30 October 2021, in the Banner Health Care System, the study cohort was split into 4213 adult patients who received Cas-Imd mAb (1200 mg) treatment compared to a PS-matched 4213 untreated patients. The primary outcomes were the incidence of all-cause hospitalization, intensive care unit (ICU) admission, and mortality within 30 days of Cas-Imd mAb administration or Delta variant infection. Results: Compared to the PS-matched untreated cohort, the Cas-Imd mAb cohort had significantly lower all-cause hospitalization (4.2% vs 17.6%; difference in percentages, -13.4 [95% confidence interval {CI}, -14.7 to -12.0]; P < .001), ICU admission (0.3% vs 2.8%; difference, -2.4 [95% CI, -3.0 to -1.9]; P < .001), and mortality (0.2% vs 2.0%; difference, -1.8 [95% CI, -2.3 to -1.3]; P < .001) within 30 days. The Cas-Imd mAb treatment was associated with lower rate of hospitalization (hazard ratio [HR], 0.22 [95% CI, .19-.26]; P < .001) and mortality (HR, 0.11 [95% CI, .06-.21]; P < .001). Conclusions: Cas-Imd mAb treatment was associated with a lower hospitalization rate, ICU admission, and mortality within 30 days among patients infected with the SARS-CoV-2 Delta variant.

RESUMO

Background: Online resources and social media have become increasingly ubiquitous in medical education. Little is known about the need for educational resources aimed at infectious disease (ID) fellows. Methods: We conducted an educational needs assessment through a survey that aimed to describe ID fellows' current use of online and social media tools, assess the value of online learning, and identify the educational content preferred by ID fellows. We subsequently convened focus groups with ID fellows to explore how digital tools contribute to fellow learning. Results: A total of 110 ID fellows responded to the survey. Over half were second-year fellows (61, 55%). Although many respondents were satisfied with the educational resources provided by their fellowship program (70, 64%), the majority were interested in an online collaborative educational resource (97, 88%). Twitter was the most popular social media platform for education and the most valued online resource for learning. Focus groups identified several themes regarding social medial learning: broadened community, low barrier to learning, technology-enhanced learning, and limitations of current tools. Overall, the focus groups suggest that fellows value social media and online learning. Conclusions: ID fellows are currently using online and social media resources, which they view as valuable educational tools. Fellowship programs should consider these resources as complementary to traditional teaching and as a means to augment ID fellow education.

RESUMO

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.

RESUMO

Importance: Recipients of solid organ transplant (SOT) experience decreased immunogenicity after COVID-19 vaccination. Objective: To summarize current evidence on vaccine responses and identify risk factors for diminished humoral immune response in recipients of SOT. Data Sources: A literature search was conducted from existence of database through December 15, 2021, using MEDLINE, Embase, Web of Science, Cochrane Library, and ClinicalTrials.gov. Study Selection: Studies reporting humoral immune response of the COVID-19 vaccines in recipients of SOT were reviewed. Data Extraction and Synthesis: Two reviewers independently extracted data from each eligible study. Descriptive statistics and a random-effects model were used. This report was prepared following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Data were analyzed from December 2021 to February 2022. Main Outcomes and Measures: The total numbers of positive immune responses and percentage across each vaccine platform were recorded. Pooled odds ratios (pORs) with 95% CIs were used to calculate the pooled effect estimates of risk factors for poor antibody response. Results: A total of 83 studies were included for the systematic review, and 29 studies were included in the meta-analysis, representing 11 713 recipients of SOT. The weighted mean (range) of total positive humoral response for antispike antibodies after receipt of mRNA COVID-19 vaccine was 10.4% (0%-37.9%) for 1 dose, 44.9% (0%-79.1%) for 2 doses, and 63.1% (49.1%-69.1%) for 3 doses. In 2 studies, 50% of recipients of SOT with no or minimal antibody response after 3 doses of mRNA COVID-19 vaccine mounted an antibody response after a fourth dose. Among the factors associated with poor antibody response were older age (mean [SE] age difference between responders and nonresponders, 3.94 [1.1] years), deceased donor status (pOR, 0.66 [95% CI, 0.53-0.83]; I2 = 0%), antimetabolite use (pOR, 0.21 [95% CI, 0.14-0.29]; I2 = 70%), recent rituximab exposure (pOR, 0.21 [95% CI, 0.07-0.61]; I2 = 0%), and recent antithymocyte globulin exposure (pOR, 0.32 [95% CI, 0.15-0.71]; I2 = 0%). Conclusions and Relevance: In this systematic review and meta-analysis, the rates of positive antibody response in solid organ transplant recipients remained low despite multiple doses of mRNA vaccines. These findings suggest that more efforts are needed to modulate the risk factors associated with reduced humoral responses and to study monoclonal antibody prophylaxis among recipients of SOT who are at high risk of diminished humoral response.

RESUMO

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.

BACKGROUND: In allogeneic haematopoietic stem cell transplant (allo-HSCT) recipients, the inter-relationship between post-transplant cytomegalovirus (CMV) and subsequent invasive fungal infections (IFIs) is conflicting and the association of CMV serostatus with IFIs has not been evaluated. OBJECTIVES: To determine the relationship between CMV infection/serostatus and IFIs in allo-HSCT populations. DATA SOURCES: A systematic literature search was conducted from existence until 11 July 2021 using Medline, Embase and ISI Web of Science databases. STUDY ELIGIBILITY CRITERIA: Cross-sectional, prospective cohort, retrospective cohort and case-control studies that reported allo-HSCT recipients with CMV and without CMV who developed or did not develop IFIs after CMV infection. PARTICIPANTS: Allo-HSCT recipients. INTERVENTIONS: Not applicable. METHODS: A systematic search, screening, data extracting and assessing study quality were independently conducted by two reviewers. The Newcastle-Ottawa scale was used to assess risk of bias. data were analysed using the pooled effect estimates of a random-effects model. RESULTS: A total of 18 and 12 studies were included for systematic review and meta-analysis, respectively. Post-transplant CMV infection significantly increased the risk of IFIs with a pooled hazard ratio (pHR) of 2.58 (1.78, 3.74), I2 = 75%. Further subgroup analyses by timing of IFIs, CMV definitions, study continents, study design and adjustment of effect estimates showed that post-transplant CMV infection consistently increased the risk of subsequent IFIs. High-risk CMV serostatus (D-/R+) increased the risk of IFIs with a pooled odds ratio (OR) of 1.33 (1.04, 1.71), I2 = 0%, but low-risk CMV serostatus (D-/R-) decreased the risk of IFIs with a pOR of 0.69 (0.55, 0.87), I2 = 0%. CONCLUSIONS: Post-transplant CMV infection and high-risk CMV serostatus increased the risk of IFIs, but low-risk CMV serostatus decreased risk of IFIs among allo-HSCT recipients. Further studies are needed to identify at-risk allo-HSCT recipients as well as to focus on fungal diagnostics and prophylaxis to prevent this fungal-after-viral phenomenon.

RESUMO

Aspergillus lentulus is a drug-resistant species that is phenotypically similar to A. fumigatus. It was discovered as a cause of azole-breakthrough disease, consistent with in vitro resistance. Clinical labs can misidentify the species as fumigatus based on phenotypic typing. We describe 4 recent cases and provide a brief review.
