Supine Blood Pressure and Risk of Cardiovascular Disease and Mortality.

Importance: Nocturnal hypertension while asleep is associated with substantial increases in risk of cardiovascular disease (CVD) and death. Whether hypertension while supine is a risk factor associated with CVD independent of seated hypertension remains unknown.

Objective: To investigate the association between supine hypertension and CVD outcomes and by hypertension treatment status.

Association of Epicardial Adipose Tissue and Ventricular Arrhythmias in Patients With Nonischemic Cardiomyopathy.

Background: Risk stratification for sudden cardiac death (SCD) in patients with nonischemic cardiomyopathy (NICM) remains challenging.

Objectives: This study aimed to investigate the impact of epicardial adipose tissue (EAT) on SCD in NICM patients.

Methods: Our study cohort included 173 consecutive patients (age 53 ± 14 years, 73% men) scheduled for primary prevention implantable cardioverter-defibrillators (ICDs) implantation who underwent preimplant cardiovascular magnetic resonance.

Multivariable Predictive Model of Postoperative Delirium in Cardiac Surgery Patients: Proteomic and Demographic Contributions.

Background: Delirium after cardiac surgery is common, morbid, and costly, but may be prevented with risk stratification and targeted intervention. In this study, we aimed to identify protein biomarkers and develop a predictive model for postoperative delirium in older patients undergoing cardiac surgery.

Methods: SomaScan analysis of 1305 proteins in the plasma from 57 older adults undergoing cardiac surgery requiring cardiopulmonary bypass was conducted to define delirium-specific protein signatures at baseline (preoperative baseline timepoint [PREOP]) and postoperative day 2 (POD2).

mRNA export factors store nascent transcripts within nuclear speckles as an adaptive response to transient global inhibition of transcription.

Several transcription inhibitors have been developed as cancer therapies. However, they show modest clinical activity, highlighting that our understanding of the cellular response to transcriptional inhibition remains incomplete. Here we report that potent inhibitors of transcription not only impact mRNA output but also markedly impair mRNA transcript localization and nuclear export.
