Managing cardiovascular disease in pregnant people: Defining the pregnancy heart team.

Cardiovascular disease is a leading cause of morbidity and mortality for pregnant patients. A significant portion of cardiac morbidity and mortality is preventable and related to poor or delayed recognition of clinical warning signs and oversights in management. The establishment of pregnancy heart teams facilitates multidisciplinary planning to improve management of people with cardiovascular disease.

Placental Pathology and Blood Pressure at Age 7: A Longitudinal Discordant Twin Analysis.

Background: Evidence suggests that the intrauterine environment shapes offspring cardiovascular disease risk. Although placental dysfunction may be an important pathophysiologic pathway, numerous parental and pregnancy characteristics that influence offspring blood pressure are strong confounders of the mechanistic role of the placenta in observational analyses of singletons. Therefore, we leverage twin- and sibling-based comparison designs to determine whether placental pathology is associated with offspring blood pressure at age 7 while mitigating major sources of confounding.

Dual Treatment of Refractory Focal Epilepsy and Obsessive-Compulsive Disorder With Intracranial Responsive Neurostimulation.

Purpose Of The Review: Intracranial neurostimulation is a well-established treatment of neurologic conditions such as drug-resistant epilepsy (DRE) and movement disorders, and there is emerging evidence for using deep brain stimulation to treat obsessive-compulsive disorder (OCD) and depression. Nearly all published reports of intracranial neurostimulation have focused on implanting a single device to treat a single condition. The purpose of this review was to educate neurology clinicians on the background literature informing dual treatment of 2 comorbid neuropsychiatric conditions epilepsy and OCD, discuss ethical and logistical challenges to dual neuropsychiatric treatment with a single device, and demonstrate the promise and pitfalls of this approach through discussion of the first-in-human closed-looped neurostimulator (RNS) implanted to treat both DRE (on-label) and OCD (off-label).

A mismatch in the expression of cell surface molecules induces tissue-intrinsic defense against aberrant cells.

Tissue-intrinsic error correction enables epithelial cells to detect abnormal neighboring cells and facilitate their removal from the tissue. One of these pathways, "interface surveillance," is triggered by cells with aberrant developmental and cell-fate-patterning pathways. It remains unknown which molecular mechanisms provide cells with the ability to compare fate between neighboring cells.

Machine perfusion of the liver and in vivo animal models: A systematic review of the preclinical research landscape.

Machine perfusion (MP) is often referred to as one of the most promising advancements in liver transplantation research of the last few decades, with various techniques and modalities being evaluated in preclinical studies using animal models.
