Changes in Gender and Racial/Ethnic Diversity in US Residency Program Applications From 2018 to 2022.

Background Residency application patterns by gender and race/ethnicity offer important insights about diversity in residency recruitment. It is unknown how the COVID-19 pandemic and virtual interviewing affected these patterns. Objective We hypothesized that the introduction of virtual interviews caused an increase in applications submitted per applicant and that there may be differences by gender and race/ethnicity. Methods We extracted publicly reported Electronic Residency Application Service application data from 2018 to 2022 for 14 residency specialties with 1000 or more applicants in 2022 by self-reported gender and underrepresented in medicine (UIM) status. We compared patterns before and after virtual interviews were introduced in 2021. Results Among 401 480 residency applicants, the average number of applications submitted per applicant increased for all specialties between 2018 and 2022 across gender and race/ethnicity. Across all years, women applied to more programs than men in 5 specialties (dermatology, neurology, obstetrics/gynecology, pediatrics, and surgery), whereas men applied to more programs than women in 3 (anesthesia, family medicine, and physical medicine and rehabilitation). Across all years, non-UIM applicants applied to more programs than UIM applicants in all 14 specialties. There were no clear changes in application patterns by gender and race/ethnicity during in-person versus virtual interview years. Conclusions The average number of applications submitted per applicant increased over time across gender and race/ethnicity. In some specialties, women applied to more programs than men, and in others vice-versa, whereas non-UIM applicants applied to more programs than UIM applicants in all specialties. Virtual interviews did not change these patterns.

Diagnosis, Prognosticators, and Management of Acute Invasive Fungal Rhinosinusitis: Multidisciplinary Consensus Statement and Evidence-Based Review with Recommendations.

BACKGROUND: Acute invasive fungal sinusitis (AIFS) is an aggressive disease that requires prompt diagnosis and multidisciplinary treatment given its rapid progression. However, there is currently no consensus on diagnosis, prognosis, and management strategies for AIFS, with multiple modalities routinely employed. The purpose of this multi-institutional and multidisciplinary evidence-based review with recommendations (EBRR) is to thoroughly review the literature on AIFS, summarize the existing evidence, and provide recommendations on the management of AIFS. METHODS: The PubMed, EMBASE, and Cochrane databases were systematically reviewed from inception through January 2022. Studies evaluating management for orbital, non-sinonasal head and neck, and intracranial manifestations of AIFS were included. An iterative review process was utilized in accordance with EBRR guidelines. Levels of evidence and recommendations on management principles for AIFS were generated. RESULTS: A review and evaluation of published literature was performed on 12 topics surrounding AIFS (signs and symptoms, laboratory and microbiology diagnostics, endoscopy, imaging, pathology, surgery, medical therapy, management of extrasinus extension, reversing immunosuppression, and outcomes and survival). The aggregate quality of evidence was varied across reviewed domains. CONCLUSION: Based on the currently available evidence, judicious utilization of a combination of history and physical examination, laboratory and histopathologic techniques, and endoscopy provide the cornerstone for accurate diagnosis of AIFS. In addition, AIFS is optimally managed by a multidisciplinary team via a combination of surgery (including resection whenever possible), antifungal therapy, and correcting sources of immunosuppression. Higher quality (i.e., prospective) studies are needed to better define the roles of each modality and determine diagnosis and treatment algorithms.

COVID-19 in vaccinated versus unvaccinated hematologic malignancy patients.

The effect of vaccination on severity of subsequent COVID-19 in patients with hematologic malignancies (HMs) is unknown. In this single-center retrospective cohort study, we found no difference in severity of COVID-19 disease in vaccinated (n = 16) versus unvaccinated (n = 54) HM patients using an adjusted multiple logistic regression model. Recent anti-B-cell therapy was associated with more severe illness.

Evaluating an Oncology Video Curriculum Designed to Promote Asynchronous Subspecialty Learning for Internal Medicine Residents.

Internal medicine (IM) residents frequently see patients in subspecialty clinics. However, there are few published core subspecialty curricula targeted to residents' learning and practical needs, and little guidance exists regarding delivery of core subspecialty content to residents rotating across multiple clinical sites. Our study objective was to evaluate a novel oncology video curriculum for IM residents as a model for asynchronous subspecialty resident learning. Using the cognitive theory of multimedia learning, we developed a five-part oncology video curriculum targeted specifically to the needs of IM residents. All second- and third-year residents rotating in oncology clinics from October 2018 to March 2019 at a single training program were invited to participate. We evaluated curricular demand, efficacy, and acceptability, using completion rates, knowledge tests, and a survey. Twenty-eight of 31 (90.3%) residents utilized the curriculum. Resident knowledge improved after utilizing the modules, by 36.9% from pre- to posttests (95% CI [31.3-42.5]; P<0.001) and 13.7% from pre- to delayed posttests (95% CI [7.5-20.0]; P<0.001). Twenty-four of 31 (77.4%) answered the survey. Most residents agreed or strongly agreed that the curriculum contributed to their knowledge (95.2%) and added educational value beyond the clinical rotation (93.1%). Our curriculum evaluation supports the asynchronous delivery of oncology education targeted to the learning needs of IM residents using a novel core video curriculum. These curricular methods provide a model for delivering subspecialty education to IM residents with complex and busy schedules.

COVID-19 in Immunocompromised Hosts: What We Know So Far.

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused significant morbidity and mortality for patients and stressed healthcare systems worldwide. The clinical features and outcomes of COVID-19 among immunosuppressed patients, who are at presumed risk of more severe disease but who may also have decreased detrimental inflammatory responses, are not well characterized. We review the existing literature on COVID-19 among immunocompromised populations ranging from patients with cancer and solid-organ transplant recipients to patients with HIV and those receiving immunomodulatory therapy for autoimmune disease. Patients with malignancy and solid-organ transplant recipients may be at increased risk of severe COVID-19 disease and death, whereas for those with other types of immunocompromise, current evidence is less clear. Overall, further prospective controlled studies are needed to determine the attributable risk of immunocompromising conditions and therapies on COVID-19 disease prognosis.

Disseminated Legionella micdadei infection in a liver transplant patient presenting as pulmonary nodules and a laryngeal lesion.

We report a liver transplant patient with disseminated Legionella micdadei infection with pulmonary, laryngeal, and suspected muscle involvement. This organism, which stains weakly acid-fast, primarily affects immunocompromised patients. The diagnosis is difficult to make; in this case, the organism was identified via molecular diagnostics on laryngeal and pulmonary biopsy tissue.

Treatment of immunocompromised COVID-19 patients with convalescent plasma.

Immunosuppressed patients such as solid organ transplant and hematologic malignancy patients appear to be at increased risk for morbidity and mortality due to coronavirus disease 2019 (COVID-19) caused by SARS coronavirus 2 (SARS-CoV-2). Convalescent plasma, a method of passive immunization that has been applied to prior viral pandemics, holds promise as a potential treatment for COVID-19. Immunocompromised patients may experience more benefit from convalescent plasma given underlying deficits in B and T cell immunity as well as contraindications to antiviral and immunomodulatory therapy. We describe our institutional experience with four immunosuppressed patients (two kidney transplant recipients, one lung transplant recipient, and one chronic myelogenous leukemia patient) treated with COVID-19 convalescent plasma through the Expanded Access Program (NCT04338360). All patients clinically improved after administration (two fully recovered and two discharged to skilled nursing facilities) and none experienced a transfusion reaction. We also report the characteristics of convalescent plasma product from a local blood center including positive SARS-CoV-2 IgG and negative SARS-CoV-2 PCR in all samples tested. This preliminary evidence suggest that convalescent plasma may be safe among immunosuppressed patients with COVID-19 and emphasizes the need for further data on the efficacy of convalescent plasma as either primary or adjunctive therapy for COVID-19.

Disseminated Acanthamoeba infection in a heart transplant recipient treated successfully with a miltefosine-containing regimen: Case report and review of the literature.

Disseminated acanthamoebiasis is a rare, often fatal, infection most commonly affecting immunocompromised patients. We report a case involving sinuses, skin, and bone in a 60-year-old woman 5 months after heart transplantation. She improved with a combination of flucytosine, fluconazole, miltefosine, and decreased immunosuppression. To our knowledge, this is the first case of successfully treated disseminated acanthamoebiasis in a heart transplant recipient and only the second successful use of miltefosine for this infection among solid organ transplant recipients. Acanthamoeba infection should be considered in transplant recipients with evidence of skin, central nervous system, and sinus infections that are unresponsive to antibiotics. Miltefosine may represent an effective component of a multidrug therapeutic regimen for the treatment of this amoebic infection.

Impact of highly active antiretroviral therapy and immunologic status on hepatitis C virus quasispecies diversity in human immunodeficiency virus/hepatitis C virus-coinfected patients.

This study analyzes the effect of highly active antiretroviral therapy (HAART), and thus immunologic status, on hepatitis C virus (HCV) load and quasispecies diversity in patients coinfected with the human immunodeficiency virus (HIV) and HCV. Three cohorts of coinfected patients were analyzed retrospectively over a period of 7 to 10 months: group A was antiretroviral drug naïve at baseline and then on HAART for the remainder of the study, group B did not receive antiretroviral therapy at any point, and group C was on HAART for the entire study. HCV quasispecies diversity was analyzed by sequencing hypervariable region 1. In a longitudinal analysis, there was no significant change from baseline in any immunologic, virologic, or quasispecies parameter in any of the three groups. However, in comparison to groups A and B, group C had significantly higher CD4+- and CD8+-cell counts, a trend toward a higher HCV load, and significantly increased number of HCV clones, entropy, genetic distance, and ratio of nonsynonymous substitutions per nonsynonymous site to synonymous substitutions per synonymous site (Ka/Ks). In addition, CD4+-cell count was positively correlated with HCV load, genetic distance, and Ka. Interestingly, patients infected with HCV genotype 2 or 3 had a significantly higher CD4+-cell count, HCV load, genetic distance, and Ka/Ks than those infected with genotype 1. These results suggest that there is no immediate effect of HAART on HCV but that, with prolonged HAART, immune restoration results in an increase in HCV load and quasispecies diversity.

The role of Sp1 and NF-kappa B in regulating CD40 gene expression.

CD40 is a member of the tumor necrosis factor receptor superfamily and is a key signaling molecule expressed by antigen-presenting cells of the immune system. In a previous paper, we demonstrated that the expression of CD40 is regulated by both post-transcriptional and post-translational processes. In this paper, we show that basal (constitutive) CD40 gene expression is regulated by a TATA-less promoter, with Sp1 as a key transcription factor. Two Sp1 binding regions were identified in the mouse CD40 promoter at positions -59 to -50 and -74 to -66. Surprisingly, Sp1-mediated CD40 transcription was reduced following lipopolysaccharide stimulation and was associated with a time-dependent reduction in Sp1 DNA binding activity. This reduction seemed to be mediated by phosphorylation of the Sp1 molecule. We also show here that CD40 expression in lipopolysaccharide-stimulated cells is up-regulated by NF-kappaB through two distinct sites. One of these sites (-128 to -119) was shown to bind p50 and p65 members of the NF-kappaB family, while the other site (-562 to -553) bound only p65. Transfectants of p65 were generated using RAW 264 cells, and it was shown that the up-regulation of CD40 mRNA expression was dependent on the presence of the p65 molecule.
