Landscape of Cyclic Vomiting Syndrome: From Bedside to Bench, Past to Present.
Neurogastroenterol Motil
January 2025
Department of Pediatrics, Medical College of Wisconsin, Milwaukee, WI, USA.
Investigations into mechanisms of cyclic(al) vomiting syndrome (CVS) began at the bedside more than a century ago. The modern era started with the formation of the Cyclic Vomiting Syndrome Association in 1993 that helped initiate robust efforts in education, advocacy, family physician conferences, scientific symposia, dedicated clinical programs, therapeutic guidelines, and research. Even today, bedside clues continue to emerge with the recent description of cannabinoid hyperemesis syndrome (CHS) and subsequent evidence of a perturbed endocannabinoid system.

The endothelin-B receptor (ETR) mediates vasodilation in young women, an effect that is absent in postmenopausal women. We have previously demonstrated that ETR-mediated vasodilation is regulated by estradiol (E) in young women; however, the impact of E on ETR function in postmenopausal women remains unknown. Accordingly, the objective of this study was to test the hypothesis that E exposure restores ETR-mediated dilation in postmenopausal women.

Department of Biomedical Engineering, University of Virginia, Charlottesville, VA, 22908, USA.
Background: Primary luminal breast cancer cells lose their identity rapidly in standard tissue culture, which is problematic for testing hormone interventions and molecular pathways specific to the luminal subtype. Breast cancer organoids are thought to retain tumor characteristics better, but long-term viability of luminal-subtype cases is a persistent challenge. Our goal was to adapt short-term organoids of luminal breast cancer for parallel testing of genetic and pharmacologic perturbations.

Menopause
January 2025
From the Department of Radiology, Mayo Clinic, Rochester, MN.
Objective: To assess the association of systolic and diastolic blood pressure (SBP and DBP) in recently menopausal women with white matter hyperintensity (WMH) volume later in life and determine whether short-term menopausal hormone therapy (mHT) modifies these associations.
Methods: Kronos Early Estrogen Prevention Study (KEEPS) was a multicenter, randomized, double-blinded, placebo-controlled 4-year mHT trial (oral conjugated equine estrogens or transdermal 17β-estradiol). KEEPS continuation was an observational follow-up of the participants 10 years after the end of mHT.
