Disparities in Antifibrotic Medication Utilization Among Veterans With Idiopathic Pulmonary Fibrosis
BackgroundTwo antifibrotic medications, pirfenidone and nintedanib, are approved for the treatment of idiopathic pulmonary fibrosis (IPF). Little is known about their real-world adoption.Research questionWhat are the real-world antifibrotic utilization rates and factors associated with uptake among a national cohort of veterans with IPF?Study design and methodsThis study identified veterans with IPF who received care either provided by the Veterans Affairs (VA) Healthcare System or non-VA care paid for by the VA. Patients who had filled at least one antifibrotic prescription through the VA pharmacy or Medicare Part D between October 15, 2014, and December 31, 2019, were identified. Hierarchical logistic regression models were used to examine factors associated with antifibrotic uptake, accounting for comorbidities, facility clustering, and follow-up time. Fine-Gray models were used to evaluate antifibrotic use by demographic factors, accounting for the competing risk of death.ResultsAmong 14,792 veterans with IPF, 17% received antifibrotics. There were significant disparities in adoption, with lower uptake associated with female sex (adjusted OR, 0.41; 95% CI, 0.27-0.63; P < .001), Black race (adjusted OR, 0.60; 95% CI, 0.49-0.73; P < .001), and rural residence (adjusted OR, 0.88; 95% CI, 0.80-0.97; P = .012). Veterans who received their index diagnosis of IPF outside the VA were less likely to receive antifibrotic therapy (adjusted OR, 0.15; 95% CI, 0.10-0.22; P < .001).InterpretationThis study is the first to evaluate the real-world adoption of antifibrotic medications among veterans with IPF. Overall uptake was low, and there were significant disparities in use. Interventions to address these issues deserve further investigation

Evaluation of Pulmonary Fibrosis Outcomes by Race and Ethnicity in US Adults
Importance: Pulmonary fibrosis (PF) is characterized by progressive scarring of lung tissue and poor survival. Racial and ethnic minority populations face the greatest risk of morbidity and mortality from disparities impacting respiratory health, but the pattern of age at clinically relevant outcomes across diverse racial and ethnic populations with PF is unknown. Objective: To compare the age at PF-related outcomes and the heterogeneity in survival patterns among Hispanic, non-Hispanic Black, and non-Hispanic White participants. Design, setting, and participants: This cohort study included adult patients with a PF diagnosis and used data from prospective clinical registries: the Pulmonary Fibrosis Foundation Registry (PFFR) for the primary cohort and registries from 4 geographically distinct tertiary hospitals in the US for the external multicenter validation (EMV) cohort. Patients were followed between January 2003 and April 2021. Exposures: Race and ethnicity comparisons between Black, Hispanic, and White participants with PF. Main outcomes and measures: Age and sex distribution of participants were measured at the time of study enrollment. All-cause mortality and age at PF diagnosis, hospitalization, lung transplant, and death were assessed in participants over 14 389 person-years. Differences between racial and ethnic groups were compared using Wilcoxon rank sum tests, Bartlett 1-way analysis of variance, and χ2 tests, and crude mortality rates and rate ratios were assessed across racial and ethnic categories using Cox proportional hazards regression models. Results: In total, 4792 participants with PF were assessed (mean [SD] age, 66.1 [11.2] years; 2779 [58.0%] male; 488 [10.2%] Black, 319 [6.7%] Hispanic, and 3985 [83.2%] White); 1904 were in the PFFR and 2888 in the EMV cohort. Black patients with PF were consistently younger than White patients (mean [SD] age at baseline, 57.9 [12.0] vs 68.6 [9.6] years; P Conclusions and relevance: In this cohort study of participants with PF, racial and ethnic disparities, especially among Black patients, were found in PF-related outcomes, including earlier onset of death. Further research is essential to identify and mitigate the underlying responsible factors.</p
Identification of Markers that Distinguish Monocyte-Derived Fibrocytes from Monocytes, Macrophages, and Fibroblasts
The processes that drive fibrotic diseases are complex and include an influx of peripheral blood monocytes that can differentiate into fibroblast-like cells called fibrocytes. Monocytes can also differentiate into other cell types, such as tissue macrophages. The ability to discriminate between monocytes, macrophages, fibrocytes, and fibroblasts in fibrotic lesions could be beneficial in identifying therapies that target either stromal fibroblasts or fibrocytes. and in sections from human lung. We found that markers such as CD34, CD68, and collagen do not effectively discriminate between the four cell types. In addition, IL-4, IL-12, IL-13, IFN-γ, and SAP differentially regulate the expression of CD32, CD163, CD172a, and CD206 on both macrophages and fibrocytes. Finally, CD49c (α3 integrin) expression identifies a subset of fibrocytes, and this subset increases with time in culture.These results suggest that discrimination of monocytes, macrophages, fibrocytes, and fibroblasts in fibrotic lesions is possible, and this may allow for an assessment of fibrocytes in fibrotic diseases
Brucellosis Prostatitis: A Neglected Diagnosis for a Tropical Disease
Fevers of unknown origin (FUO) remain a diagnostic challenge despite recent advances in diagnostic modalities including serological testing and imaging techniques. We report a case of FUO subsequently found to be acute prostatitis secondary to brucellosis in an immigrant from Mexico. A 74-year-old Mexican man who had immigrated to the USA 2Â months prior presented to the emergency room with fever, dysuria, watery diarrhea, and tender prostate. Blood cultures collected during a febrile episode grew
Brucella melitensis
9Â days after collection. The
Brucella
IgM antibody was also positive. He was started on treatment with intravenous gentamicin, oral rifampin, and oral doxycycline. The patient’s fever, abdominal symptoms, and dysuria resolved. His case highlights the importance of including brucellosis in the differential diagnosis in patients presenting with FUO with the appropriate risk factors
Variability in Global Prevalence of Interstitial Lung Disease
International audienceThere are limited epidemiologic studies describing the global burden and geographic heterogeneity of interstitial lung disease (ILD) subtypes. We found that among seventeen methodologically heterogenous studies that examined the incidence, prevalence and relative frequencies of ILDs, the incidence of ILD ranged from 1 to 31.5 per 100,000 person-years and prevalence ranged from 6.3 to 71 per 100,000 people. In North America and Europe, idiopathic pulmonary fibrosis and sarcoidosis were the most prevalent ILDs while the relative frequency of hypersensitivity pneumonitis was higher in Asia, particularly in India (10.7–47.3%) and Pakistan (12.6%). The relative frequency of connective tissue disease ILD demonstrated the greatest geographic variability, ranging from 7.5% of cases in Belgium to 33.3% of cases in Canada and 34.8% of cases in Saudi Arabia. These differences may represent true differences based on underlying characteristics of the source populations or methodological differences in disease classification and patient recruitment (registry vs. population-based cohorts). There are three areas where we feel addition work is needed to better understand the global burden of ILD. First, a standard ontology with diagnostic confidence thresholds for comparative epidemiology studies of ILD is needed. Second, more globally representative data should be published in English language journals as current literature has largely focused on Europe and North America with little data from South America, Africa and Asia. Third, the inclusion of community-based cohorts that leverage the strength of large databases can help better estimate population burden of disease. These large, community-based longitudinal cohorts would also allow for tracking of global trends and be a valuable resource for collective study. We believe the ILD research community should organize to define a shared ontology for disease classification and commit to conducting global claims and electronic health record based epidemiologic studies in a standardized fashion. Aggregating and sharing this type of data would provide a unique opportunity for international collaboration as our understanding of ILD continues to grow and evolve. Better understanding the geographic and temporal patterns of disease prevalence and identifying clusters of ILD subtypes will facilitate improved understanding of emerging risk factors and help identify targets for future intervention
Using Visual Arts Education and Reflective Practice to Increase Empathy and Perspective Taking in Medical Students
INTRODUCTION: Empathy is a critical competency for health care providers. However, empathy levels in medical students and residents have been shown to paradoxically decrease during training. Arts and humanities education and reflective practice may reduce burnout and promote empathy during medical school.
METHODS: We developed and implemented an art education elective for medical students focusing on observation and reflective practice and measured its impact on empathy. Between 2017 and 2022, first-year medical students were offered an annual, 4-week elective led by art educators that featured visualization exercises and discussions on the role of bias and perspective in art interpretation. Curriculum effectiveness and impact on empathy were measured using the validated Interpersonal Reactivity Index (IRI) and self-assessments.
RESULTS: One hundred twenty-eight students participated in the elective over a 5-year period; 89 (70%) completed assessments. Students reported improvements in empathic communication, recognition of bias, and observation skills. IRI data demonstrated a significant increase in perspective taking (19.0 vs. 20.2; p \u3c .0125).
DISCUSSION: Participation in the elective was associated with self-reported improvements in visual observation, awareness of bias, and empathetic communication. IRI results showed that participants also demonstrated improved perspective taking. Since perspective taking is a cognitive component of empathy, we have provided some empirical evidence that arts education in medical school can promote empathic attitudes and skills
