Inheritance of Imaging Parameters of Arrhythmic Risk in Mitral Valve Prolapse: A Pedigree Study.
Circ Cardiovasc Imaging
January 2025
Division of Cardiology, Department of Medicine, University of California, San Francisco (L.C., S.D., D.B., J.J.T., Q.F., L.T., A.H.R., R.J., S.H., H.H.H., Z.H.T., N.B.S., F.N.D.).
Background: A subset of patients with mitral valve prolapse (MVP), a highly heritable condition, experience sudden cardiac arrest (SCA) or sudden cardiac death (SCD). However, the inheritance of phenotypic imaging features of arrhythmic MVP remains unknown.
Methods: We recruited 23 MVP probands, including 9 with SCA/SCD and 14 with frequent/complex ventricular ectopy.
Treatment of discoid lupus erythematosus scarring alopecia with deucravacitinib: A case report.
SAGE Open Med Case Rep

Division of Dermatology, Faculty of Medicine, University of Ottawa, Ottawa, ON, Canada.
Discoid lupus erythematosus is a chronic, recurring, autoimmune skin disease causing annular, scarring plaques on the head and neck. Deucravacitinib, a tyrosine kinase 2 inhibitor in the Janus kinase inhibitor family, represents an emerging treatment option in systemic lupus erythematosus with potential applicability to discoid lupus erythematosus. We describe a 48-year-old woman with multiple treatment-refractory scalp plaques and associated alopecia treated with deucravacitinib.

Division of Cardiovascular Medicine, Brigham and Women's Hospital Harvard Medical School Boston MA USA.
Background: This study aims to characterize right ventricular dysfunction (RVD) in heart failure (HF) with preserved ejection fraction and understand the cumulative prognostic value of abnormal RV echocardiographic parameters in HF with preserved ejection fraction.
Methods And Results: Data from 809 patients in the PARAGON-HF (Prospective Comparison of Angiotensin Receptor-Neprilysin Inhibitor With Angiotensin-Receptor Blocker Global Outcomes in HF With Preserved Ejection Fraction) echocardiographic substudy (55% women, mean age 74±8 years) were analyzed. Correlates of RVD (defined as tricuspid annular plane systolic excursion <1.
Non-lytic spread of poliovirus requires the nonstructural protein 3CD.

Department of Microbiology and Immunology, The University of North Carolina at Chapel Hill, Chapel Hill, North Carolina, USA.
Unlabelled: Non-enveloped viruses like poliovirus (PV) have evolved the capacity to spread by non-lytic mechanisms. For PV, this mechanism exploits the host secretory autophagy pathway. Virions are selectively incorporated into autophagosomes, double-membrane vesicles that travel to the plasma membrane, fuse, and release single-membrane vesicles containing virions.
