Paying for Parenthood: Understanding Parental Leave Policies in Infectious Disease Fellowship.

Background: Many physician trainees plan pregnancy during residency and fellowship. A study of internal medicine program directors (PDs) demonstrated frequent misinterpretation of American Board of Internal Medicine (ABIM) leave policies applied to parental leave. The primary aim was to investigate how infectious disease (ID) PDs interpret current ABIM leave policies. Methods: We surveyed 155 ID PDs in an online anonymous questionnaire about knowledge of ABIM leave policies and application toward trainee leaves. Results: Of 155 PDs, 56 (36%) responded to the survey. Nearly 70% incorrectly identified leave limits permitted. A majority mistakenly chose to extend training when a competent fellow was within the allowed duration of leave. PDs reported that the majority of ID trainee maternity/birth parent leaves (60%) were ≤7 weeks and only 7% were ≥12 weeks; 50% of paternity/nonbirth parent leaves were ≤3 weeks. Conclusions: Surveyed ID fellowship PDs often misinterpret ABIM leave policies and apply policies incorrectly when given sample scenarios..

Teaching Everyone Everywhere All at Once: Leveraging Social Media to Implement a Multisite Fungal Diagnostics Curriculum.

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.

Inclusion, Diversity, Access, and Equity in Infectious Diseases Fellowship Training: Tools for Program Directors.

The Infectious Diseases Society of America (IDSA) has set clear priorities in recent years to promote inclusion, diversity, access, and equity (IDA&E) in infectious disease (ID) clinical practice, medical education, and research. The IDSA IDA&E Task Force was launched in 2018 to ensure implementation of these principles. The IDSA Training Program Directors Committee met in 2021 and discussed IDA&E best practices as they pertain to the education of ID fellows. Committee members sought to develop specific goals and strategies related to recruitment, clinical training, didactics, and faculty development. This article represents a presentation of ideas brought forth at the meeting in those spheres and is meant to serve as a reference document for ID training program directors seeking guidance in this area.

Mistaken Identity: Many Diagnoses are Frequently Misattributed to Lyme Disease.

BACKGROUND: Prior studies have demonstrated that Lyme disease is frequently over-diagnosed. However, few studies describe which conditions are misdiagnosed as Lyme disease. METHODS: This retrospective observational cohort study evaluated patients who lacked evidence for Borrelia burgdorferi infection referred for Lyme disease to a Mid-Atlantic academic center from 2000-2013. The primary outcome is clinically described diagnoses contributing to symptoms. Secondary outcomes included symptom duration and determination whether diagnoses were new or attributed to existing medical conditions. RESULTS: Of 1261 referred patients, 1061 (84%) had no findings of active Lyme disease, with 690 (65%) receiving other diagnoses; resulting in 405 (59%) having newly diagnosed medical conditions, 134 (19%) attributed to pre-existing medical issues, and 151 (22%) with both new and pre-existing conditions. Among the 690 patients, the median symptom duration was 796 days, and a total of 139 discrete diagnoses were made. Infectious disease diagnoses comprised only 3.2%. Leading diagnoses were anxiety/depression 222 (21%), fibromyalgia 120 (11%), chronic fatigue syndrome 77 (7%), migraine disorder 74 (7%), osteoarthritis 62 (6%), and sleep disorder/apnea 48 (5%). Examples of less frequent but non-syndromic diseases newly diagnosed included multiple sclerosis (n = 11), malignancy (n = 8), Parkinson's disease (n = 8), sarcoidosis (n = 4), or amyotrophic lateral sclerosis (n = 4). CONCLUSIONS: Most patients with long-term symptoms have either new or pre-existing disorders accounting for their symptoms other than Lyme disease, suggesting overdiagnosis in this population. Patients referred for consideration of Lyme disease for chronic symptoms deserve careful assessment for diagnoses other than Borrelia burgdorferi infection.

Virtual Recruitment Is Here to Stay: A Survey of ID Fellowship Program Directors and Matched Applicants Regarding Their 2020 Virtual Recruitment Experiences.

BACKGROUND: Graduate Medical Education training programs transitioned to all-virtual recruitment in 2020. Limited data have been published regarding the consequences of this transition. We aimed to understand (1) infectious diseases (ID) fellowship programs' recruitment efforts and the effect of virtual recruitment on application and interview numbers and (2) the number of programs to which matched applicants applied and interviewed and applicants' perspectives on virtual recruitment. METHODS: In 2020-2021, we surveyed all US ID fellowship program directors (PDs) and matched applicants. Descriptive data analysis was performed on quantitative survey items. Free-text responses were analyzed through a quantitative content analysis approach. RESULTS: The PD response rate was 68/158 (43%); the applicant response rate was at least 23% (85/365). PDs reported a 27% increase in mean number of applications received and a 45% increase in mean number of applicants interviewed compared with the previous year. Applicants especially valued the online program structure information, PD program overview videos, didactic and curriculum content, and fellow testimonials and profiles. Most applicants preferred interviews lasting no more than 40 minutes and interview days lasting no more than 5 hours. Nearly all (60/64, 94%) PDs adequately learned about candidates; most (48/64, 75%) felt unable to showcase their program as well as when in-person. Most PDs (54/64, 84%) and applicants (56/73, 77%) want an option for virtual recruitment. CONCLUSIONS: Virtual recruitment enabled programs to accommodate more applicants and highlighted applicants' preferences for programs' augmented online presences and time-limited interview days. Most programs and applicants want an option for virtual interviews.

Tocilizumab for the Treatment of COVID-19 Among Hospitalized Patients: A Matched Retrospective Cohort Analysis.

BACKGROUND: There is currently no single treatment that mitigates all harms caused by severe acute respiratory syndrome coronavirus 2 infection. Tocilizumab, an interleukin-6 antagonist, may have a role as an adjunctive immune-modulating therapy. METHODS: This was an observational retrospective study of hospitalized adult patients with confirmed coronavirus disease 2019 (COVID-19). The intervention group comprised patients who received tocilizumab; the comparator arm was drawn from patients who did not receive tocilizumab. The primary outcome was all-cause mortality censored at 28 days; secondary outcomes were all-cause mortality at discharge, time to clinical improvement, and rates of secondary infections. Marginal structural Cox models via inverse probability treatment weights were applied to estimate the effect of tocilizumab. A time-dependent propensity score-matching method was used to generate a 1:1 match for tocilizumab recipients; infectious diseases experts then manually reviewed these matched charts to identify secondary infections. RESULTS: This analysis included 90 tocilizumab recipients and 1669 controls. Under the marginal structural Cox model, tocilizumab was associated with a 62% reduced hazard of death (adjusted hazard ratio [aHR], 0.38; 95% CI, 0.21 to 0.70) and no change in time to clinical improvement (aHR, 1.13; 95% CI, 0.68 to 1.87). The 1:1 matched data set also showed a lower mortality rate (27.8% vs 34.4%) and reduced hazards of death (aHR, 0.47; 95% CI, 0.25 to 0.88). Elevated inflammatory markers were associated with reduced hazards of death among tocilizumab recipients compared with controls. Secondary infection rates were similar between the 2 groups. CONCLUSIONS: Tocilizumab may provide benefit in a subgroup of patients hospitalized with COVID-19 who have elevated biomarkers of hyperinflammation, without increasing the risk of secondary infection.

Education of Infectious Diseases Fellows During the COVID-19 Pandemic Crisis: Challenges and Opportunities.

One of the many challenges that has befallen the Infectious Diseases and Graduate Medical Education communities during the coronavirus disease 2019 (COVID-19) pandemic is the maintenance of continued effective education and training of the future leaders of our field. With the remarkable speed and innovation that has characterized the responses to this pandemic, educators everywhere have adapted existing robust and safe learning environments to meet the needs of our learners. This paper will review distinct aspects of education and training of the Infectious Diseases fellows we believe the COVID-19 pandemic has impacted most, including mentoring, didactics, and wellness. We anticipate that several strategies developed in this context and described herein will help to inform training and best practices during the pandemic and beyond.

Impact of Coronavirus Disease 2019 on Infectious Diseases Fellows in the United States: Perspectives From the First National Infectious Diseases Fellows Call.

The coronavirus disease 2019 (COVID-19) pandemic has affected many providers, but its impact on Infectious Diseases (ID) fellows in the United States is largely undescribed. In this study, we discuss key issues that emerged from the first national ID Fellows Call with respect to the ID fellow's role during the COVID-19 pandemic, teaching/learning, and research.

Randomized Trial of a Vaccine Regimen to Prevent Chronic HCV Infection.

BACKGROUND: A safe and effective vaccine to prevent chronic hepatitis C virus (HCV) infection is a critical component of efforts to eliminate the disease. METHODS: In this phase 1-2 randomized, double-blind, placebo-controlled trial, we evaluated a recombinant chimpanzee adenovirus 3 vector priming vaccination followed by a recombinant modified vaccinia Ankara boost; both vaccines encode HCV nonstructural proteins. Adults who were considered to be at risk for HCV infection on the basis of a history of recent injection drug use were randomly assigned (in a 1:1 ratio) to receive vaccine or placebo on days 0 and 56. Vaccine-related serious adverse events, severe local or systemic adverse events, and laboratory adverse events were the primary safety end points. The primary efficacy end point was chronic HCV infection, defined as persistent viremia for 6 months. RESULTS: A total of 548 participants underwent randomization, with 274 assigned to each group. There was no significant difference in the incidence of chronic HCV infection between the groups. In the per-protocol population, chronic HCV infection developed in 14 participants in each group (hazard ratio [vaccine vs. placebo], 1.53; 95% confidence interval [CI], 0.66 to 3.55; vaccine efficacy, -53%; 95% CI, -255 to 34). In the modified intention-to-treat population, chronic HCV infection developed in 19 participants in the vaccine group and 17 in placebo group (hazard ratio, 1.66; 95% CI, 0.79 to 3.50; vaccine efficacy, -66%; 95% CI, -250 to 21). The geometric mean peak HCV RNA level after infection differed between the vaccine group and the placebo group (152.51×103 IU per milliliter and 1804.93×103 IU per milliliter, respectively). T-cell responses to HCV were detected in 78% of the participants in the vaccine group. The percentages of participants with serious adverse events were similar in the two groups. CONCLUSIONS: In this trial, the HCV vaccine regimen did not cause serious adverse events, produced HCV-specific T-cell responses, and lowered the peak HCV RNA level, but it did not prevent chronic HCV infection.

Sharing the cure: Building primary care and public health infrastructure to improve the hepatitis C care continuum in Maryland.

In 2014, trained healthcare provider capacity was insufficient to deliver care to an estimated 70 000 persons in Maryland with chronic hepatitis C virus (HCV) infection. The goal of Maryland Community Based Programs to Test and Cure Hepatitis C, a public health implementation project, was to improve HCV treatment access by expanding the workforce. Sharing the Cure (STC) was a package of services deployed 10/1/14-9/30/18 that included enhanced information technology and public health infrastructure, primary care provider training and practice transformation. Nine primary care sites enrolled. HCV clinical outcomes were documented among individuals who presented for care at sites and met criteria for HCV testing including risk factor or birth cohort (born between 1945 and 1965) based testing. Fifty-three providers completed the STC training. STC providers identified 3237 HCV antibody-positive patients of which 2624 (81%) were RNA+. Of those HCV RNA+, 1739 (66%) were staged, 932 (36%) were prescribed treatment, 838 (32%) started treatment, 721 (27%) completed treatment and 543 (21%) achieved cure. Among 1739 patients staged, 693 (40%) patients had a liver fibrosis assessment score < F2, rendering them ineligible for treatment under Maryland Medicaid guidelines. HCV RNA testing among HCV antibody-positive people increased from 40% (baseline) to 95% among STC providers. Of 554 patients with virologic data reported, 543 (98%) achieved cure. Primary care practices can effectively serve as HCV treatment centers to expand treatment access. However, criteria by insurance providers in Maryland were a major barrier to treatment.

The Struggling Infectious Diseases Fellow: Remediation Challenges and Opportunities.

Remediation of struggling learners is a challenge faced by all educators. In recognition of this reality, and in light of contemporary challenges facing infectious diseases (ID) fellowship program directors, the Infectious Diseases Society of America Training Program Directors' Committee focused the 2018 National Fellowship Program Directors' Meeting at IDWeek on "Remediation of the Struggling Fellow." Small group discussions addressed 7 core topics, including feedback and evaluations, performance management and remediation, knowledge deficits, fellow well-being, efficiency and time management, teaching skills, and career development. This manuscript synthesizes those discussions around a competency-based framework to provide program directors and other educators with a roadmap for addressing common contemporary remediation challenges.

Misdiagnosis of Lyme Disease With Unnecessary Antimicrobial Treatment Characterizes Patients Referred to an Academic Infectious Diseases Clinic.

BACKGROUND: Although Lyme disease is the most common vector-borne infection in the United States, diagnostic accuracy within community settings is not well characterized. METHODS: A retrospective observational cohort study of patients referred to an academic center with a presumed diagnosis or concern for Lyme disease between 2000 and 2013 was performed to analyze diagnoses and treatments. Characteristics of those with Lyme disease and those misdiagnosed as having Lyme disease were compared. RESULTS: Of 1261 patients, 911 (72.2%) did not have Lyme disease, 184 (14.6%) had active or recent Lyme disease, 150 (11.9%) had a remote history of Lyme disease, and 16 (1.3%) were identified as having possible Lyme disease. Patients without current Lyme disease were more likely to be female (odds ratio [OR], 1.56; 95% confidence interval [CI], 1.08-2.45), to have had symptoms for >3 months (OR, 8.78; 95% CI, 5.87-13.1), to have higher symptom counts (OR per additional symptom, 1.08; 95% CI, 1.02-1.13), to have had more Lyme-related laboratory testing (OR per additional laboratory test, 1.17; 95% CI, 1.03-1.32), and to have been diagnosed with what were regarded as coinfections (OR, 3.13; 95% CI, 1.14-8.57). Of the 911 patients without Lyme disease, 764 (83.9%) had received antimicrobials to treat Lyme disease or their coinfections. The percentage of patients established to have Lyme disease was lower than in earlier studies of referred populations. CONCLUSIONS: Among patients referred to an academic Infectious Diseases practice for Lyme disease, incorrect diagnoses and unnecessary antibiotic treatment were common, both for Lyme disease and for coinfections.

Pressure pain thresholds: Subject factors and the meaning of peak pressures.

BACKGROUND: The assessment of pressure pain has become an integral part in pain research. The distribution of pressure under a plunger can be uneven. However, measurements based on conventional devices show the applied force or mean pressure, failing to take local pressure peaks into account. Our main question was whether peak pressures under the probe are responsible for pain onset. METHODS: A force-controlled algometer was fitted with a newly developed pressure-indicating film. Pressure pain thresholds (PPTs) of 100 healthy subjects (57 men, age 18-66 years) were assessed at 29 sites across the body. Each site was measured three times, nonconsecutively and presented in randomized order. Forty subjects were manual labourers. RESULTS: Pressure distributions on hard tissue (bone) were more heterogeneous and showed more prominent peaks beneath the probe when reaching the PPT. Soft tissue (e.g. muscle) created a distinct distribution, with higher pressure especially around the corners of the probe. A high variability of PPTs between subjects and different measurement sites was observed. Men as well as manual labourers had comparatively higher adjusted pressure pain thresholds (force and pressure). CONCLUSIONS: Peak pressures could be relevant for pain onset and should be accounted for in mechanical pain studies. The probe, indentation depth and tissue properties have a major impact on pressure distributions and may therefore affect the perception of pressure pain. Due to higher intra-individual differences regarding peak pressures at the spinous processes, breastbone, forehead and abdomen caution are needed when interpreting those sites. SIGNIFICANCE: This study adds some important considerations for the use of pressure algometers. It was found that during pressure pain thresholds readings distinct peak pressure profiles could arise, which may influence the perception of pain. Peak pressure could be another contributing factor, which may explain some of the high variability in pressure pain readings.

An acute exposure to ozone impairs human olfactory functioning.

INTRODUCTION: Ozone is a ubiquitous and irritant gas. We questioned whether an acute exposure to 0.2 ppm ozone impaired olfactory functioning. METHODS: Healthy, normosmic subjects were exposed according to a parallel group design either to 0.2 ppm ozone (n = 15) or to sham (n = 13) in an exposure chamber for two hours. Possible irritating effects were assessed by questionnaire (range 0-5). The detection threshold of n-butanol was measured with the Sniffin' Sticks test before and after exposure. Olfactory thresholds were logarithmized and a two-way analysis of variance (ANOVA) with repeated measurements was carried out to test the effects of exposure (ozone vs. sham) and time (before vs. after exposure). Additionally, nasal secretions were taken at a preliminary examination and after exposure to determine interleukins 1ß and 8. RESULTS: No irritating effects to the upper airways were observed. In the ozone group, the median score for cough increased from 0 to 2 at the end of exposure (sham group 0 and 0, respectively, p < 0.001). The ANOVA showed a main effect for ozone exposure (F (1, 26) = 27.6, p = 0.0002), indicating higher olfactory thresholds in the ozone group. Concentrations of interleukins in nasal secretions did not increase following ozone exposure. CONCLUSIONS: This study shows a clear impairment of olfactory functioning following an acute exposure to 0.2 ppm ozone.

Internal Medicine Residents' Knowledge and Practice of Pulmonary Tuberculosis Diagnosis.

BACKGROUND: Internal medicine physicians are often the first providers to encounter patients with a new diagnosis of tuberculosis. Given the public health risks of missed tuberculosis cases, assessing internal medicine residents' ability to diagnose tuberculosis is important. METHODS: Internal medicine resident knowledge and practice patterns in pulmonary tuberculosis diagnosis at 7 academic hospitals were assessed utilizing (a) a 10-item validated pulmonary tuberculosis diagnosis assessment tool and (b) a retrospective chart review of 343 patients who underwent a pulmonary tuberculosis evaluation while admitted to a resident-staffed internal medicine or infectious disease service. Our primary outcomes were the mean score and percentage of correct responses per assessment tool question, and the percentage of patients who had Centers for Disease Control and Prevention-recommended tuberculosis diagnostic tests obtained. RESULTS: Of the 886 residents who received the assessment, 541 responded, yielding a response rate of 61%. The mean score on the assessment tool (SD) was 4.4 (1.6), and the correct response rate was 57% (311/541) or less on 9 of 10 questions. On chart review, each recommended test was obtained for ≤43% (148/343) of patients, other than chest x-ray (328/343; 96%). A nucleic acid amplification test was obtained for 18% (62/343) of patients, whereas 24% (83/343) had only 1 respiratory sample obtained. Twenty patients were diagnosed with tuberculosis. CONCLUSIONS: Significant knowledge and practice gaps exist in internal medicine residents' abilities to diagnose tuberculosis. As residents represent the future providers who will be evaluating patients with possible tuberculosis, such deficiencies must be addressed.

Developing an Assessment Framework for Essential Internal Medicine Subspecialty Topics.

BACKGROUND: Assessing residents by direct observation is the preferred assessment method for infrequently encountered subspecialty topics, but this is logistically challenging. OBJECTIVE: We developed an assessment framework for internal medicine (IM) residents in subspecialty topics, using tuberculosis diagnosis for proof of concept. METHODS: We used a 4-step process at 8 academic medical centers that entailed (1) creating a 10-item knowledge assessment tool; (2) pilot testing on a sample of 129 IM residents and infectious disease fellow volunteers to evaluate validity evidence; (3) implementing the final tool among 886 resident volunteers; and (4) assessing outcomes via retrospective chart review. Outcomes included tool score, item performance, and rates of obtaining recommended diagnostics. RESULTS: Following tool development, 10 infectious disease experts provided content validity. Pilot testing showed higher mean scores for fellows compared with residents (7 [SD = 1.8] versus 3.8 [SD = 1.7], respectively, P < .001) and a satisfactory Kuder-Richardson Formula 20 (0.72). Implementation of the tool revealed a 14-minute (SD = 2.0) mean completion time, 61% (541 of 886) response rate, 4.4 (SD = 1.6) mean score, and ≤ 57% correct response rate for 9 of 10 items. On chart review (n = 343), the rate of obtaining each recommended test was ≤ 43% (113 of 261), except for chest x-rays (96%, 328 of 343). CONCLUSIONS: Our assessment framework revealed knowledge and practice gaps in tuberculosis diagnosis in IM residents. Adopting this approach may help ensure assessment is not limited to frequently encountered topics.

Laser irradiation of Mg-Al-Zn alloy: Reduced electrochemical kinetics and enhanced performance in simulated body fluid.

As a lightweight metal with mechanical properties similar to natural bone, Mg and its alloys are great prospects for biodegradable, load bearing implants. However, rapid degradation and H2 gas production in physiological media has prevented widespread use of Mg alloys. Surface heterogeneities in the form of intermetallic particles dominate the corrosion response. This research shows that surface homogenization significantly improved the biological corrosion response observed during immersion in simulated body fluid (SBF). The laser processed Mg alloy exhibited a 50% reduction in mass loss and H2 evolution after 24 h of immersion in SBF when compared to the wrought, cast alloy. The laser processed samples exhibited increased wettability as evident from wetting angle studies, further suggesting improved biocompatibility. Electrochemical analysis by potentiodynamic polarization measurements showed that the anodic and cathodic kinetics were reduced following laser processing and are attributed to the surface chemical homogeneity.
