Effects of early-life F-53B exposure on thyroid function in juvenile rats: The role of the cAMP signaling pathway.

Chlorinated polyfluoroalkyl ether sulfonate (F-53B), a substitute for perfluorooctane sulfonate (PFOS), exerts a stronger effect on neonatal thyroid hormone (TH) than PFOS. However, limited data on its thyrotoxicity complicates early-life risk assessment. Here, Sprague-Dawley rats were gavaged with F-53B (0, 8, 80, 800 μg/kg/d) for 63 days, from two weeks pre-pregnancy to two weeks post-weaning.

Outcomes of Patients with Cancer Admitted with Heart Failure-Associated Cardiogenic Shock.

Background: Acute decompensated heart failure (HF) can progress to cardiogenic shock, and patients with cancer are at an increased risk of HF compared to patients without cancer. However, limited data exist on outcomes of patients admitted for HF-related cardiogenic shock (HF-CS) with cancer versus without cancer.

Methods: Adult patients admitted for HF-CS between 2014-2020 were identified using the National Readmission Database.

Ixodes scapularis Tick Parasitizing Dog in Dawson County, Montana, USA, 2023.

In October 2023, a partially engorged female Ixodes tick was removed from a dog in Bozeman, Montana, USA, that had recently spent time in eastern Montana. The tick was identified as I. scapularis according to morphologic characteristics and genomic sequencing, suggesting an expanded geographic distribution requiring continued public health surveillance.

Racial and ethnic differences in prenatal exposure to environmental phenols and parabens in the ECHO Cohort.

Background: Research suggests racial/ethnic disparities in prenatal exposure to endocrine disrupting environmental phenols (EPs) in limited populations. However, no studies have investigated racial/ethnic disparities in prenatal EP exposure across the U.S.

Risk of Post-Transplant Malignancy After Isolated Heart Transplant Among Adult Patients With Congenital Heart Disease.

Introduction: Patients with congenital heart disease (CHD) are at increased risk of cancer. In patients with CHD and advanced heart failure, isolated heart transplantation (HT) can be considered. In the overall HT population, immunosuppression after HT increases the risk of post-transplant malignancy (PTM).
