INTRODUCTION: We aimed to compare pregnancy outcomes of women with inflammatory bowel disease using biosimilar vs originator infliximab (IFX). METHODS: In a prospective cohort of pregnant women with inflammatory bowel disease, we collected characteristics, medications, pregnancy outcomes, and developmental milestones. We compared outcomes by IFX biosimilar or originator use via bivariate statistics. RESULTS: A total of 100 pregnant women on originator IFX and 20 on biosimilar IFX were included. There were no differences in pregnancy complications between groups (48% vs 35%, P = 0.29). Infant developmental milestones were comparable at 12 months. DISCUSSION: Biosimilar IFX is not associated with adverse pregnancy or infant outcomes.

Abstract A cluster of macrolide-resistant Mycoplasma pneumoniae -causing community-acquired pneumonia was observed in children in North Dakota in 2024. Suspicion was raised by non-response to macrolides, with confirmation via a polymerase-chain reaction assay. Prompt improvement occurred after the initiation of alternative antibiotics.

Abstract In 2003, the Institute of Medicine noted the need to improve workforce diversity. The American Society of Hematology (ASH) responded by developing the Minority Recruitment Initiative (MRI) to recruit diverse physicians/scientists into hematology. We evaluated the outcomes of the program. From 2004 to 2022, there were 405 awardees. Compared with national estimates, MRI awardees were less likely to discontinue their degree programs. MRI graduate student awardees had 0% attrition (97.5% confidence interval [CI], 10.6), whereas the national minority graduate student attrition was 36%. Medical student awardees had 2.2% (95% CI, 0.61-5.6) attrition, compared with the minority medical school attrition of 5.6%. Awardees were more likely than expected to pursue hematology-oncology (5.7% minority national estimate) because 14.4% (95% CI, 8.1-23.0) of medical student awardees and 88.5% (95% CI, 70.0-97.6) of early career awardees remain in the field. ASH has developed a successful program, but continued efforts are needed to advance equity in hematology.

AbstractBackground and purposeLower left atrial (LA) function is associated with higher dementia risk and may be mechanistically linked through vascular brain injury, an established correlate for higher dementia risk. Using data from the Atherosclerosis Risk in Communities study, we assessed the cross‐sectional association between LA function and brain magnetic resonance imaging (MRI) markers of vascular brain injury.MethodsWe included 1488 participants who were free of prevalent dementia, stroke, or atrial fibrillation and who underwent a two‐dimensional echocardiogram and brain MRI in 2011–2013 (mean [± standard deviation] age 76 [± 5] years, 60% female, 27% Black). LA function measures (reservoir, conduit, contractile strain) were assessed in quartiles. Brain MRI measures included cerebral microbleeds, brain infarcts, and white matter hyperintensity (WMH) volume. Logistic regression was used for dichotomous outcomes. Linear regression was used for WMH volume.ResultsOverall, 343 (23%) and 344 participants (23%) had ≥1 cerebral microbleed or brain infarct. After multivariable adjustments, the lowest LA reservoir and conduit strain quartiles (vs. highest quartile) were associated with higher odds of the presence of ≥1 cerebral microbleed (odds ratios [95% confidence intervals] 1.78 [1.42–2.22] and 1.52 [1.22–1.90]). Compared to the highest quartile, participants in the lowest LA conduit strain quartile had 1.51 (95% confidence interval 1.22–1.88) times higher odds of having ≥1 brain infarct. Lower LA contractile strain was associated with lower odds of brain infarcts. No association with WMH volume was noted.ConclusionsWe found that LA reservoir and conduit strain were associated with cerebral microbleeds and brain infarcts. Lower LA function may be linked to dementia risk via vascular brain injury. Prospective studies are needed to confirm these findings.
