The Association between Pregnancy Complications and Long-Term Maternal Cardiometabolic Health in the MIREC Cohort Study.

Context: During pregnancy, women who experience certain pregnancy complications show elevations in biomarkers of inflammation and insulin resistance; however, few studies have examined these cardiometabolic biomarkers in the decade following pregnancy.

Objective: To examine the association between pregnancy complications and cardiometabolic biomarkers 9 years postpartum including: blood pressure, blood lipids, body fat percentage, insulin resistance (glucose, insulin, proinsulin, C-peptide, HOMA-IR, HbA1c, leptin, adiponectin) and inflammation (hs-C-reactive protein).

Methods: Using data from the Maternal-Infant Research on Environmental Chemicals (MIREC) cohort study (2008-2021) we determined 3 groups of pregnancy complications: 1) hypertensive disorders of pregnancy (HDP) (n=35); any pregnancy complication in the index pregnancy, defined as preterm birth, HDP, impaired glucose tolerance or gestational diabetes mellitus (GDM) (n=55); or self-reported recurrence of one of these pregnancy complications (n=19).

Integrating Videoconferencing Therapist Guidance Into Stepped Care Internet-Delivered Cognitive Behavioral Therapy for Child and Adolescent Anxiety: Noninferiority Randomized Controlled Trial.

Background: Self-guided internet-delivered cognitive behavioral therapy (ICBT) achieves greater reach than ICBT delivered with therapist guidance, but demonstrates poorer engagement and fewer clinical benefits. Alternative models of care are required that promote engagement and are effective, accessible, and scalable.

Objective: This randomized trial evaluated whether a stepped care approach to ICBT using therapist guidance via videoconferencing for the step-up component (ICBT-SC[VC]) is noninferior to ICBT with full therapist delivery by videoconferencing (ICBT-TG[VC]) for child and adolescent anxiety.

VLDL triglycerides and cholesterol in non-alcoholic fatty liver disease and myocardial infarction.

Background And Aims: Myocardial infarction is a leading cause of death in individuals with non-alcoholic fatty liver disease (NAFLD). The two diseases share elevated very low-density lipoproteins (VLDL) carrying both triglycerides and cholesterol; however, in NAFLD mainly triglycerides accumulate in liver cells while in myocardial infarction mainly cholesterol accumulates in the atherosclerotic plaque. We hypothesized that VLDL triglycerides preferentially associate with risk of NAFLD, while VLDL cholesterol preferentially associates with risk of myocardial infarction.

Pseudorabies virus infection triggers pUL46-mediated phosphorylation of connexin-43 and closure of gap junctions to promote intercellular virus spread.

Gap junctions (GJs) play a pivotal role in intercellular communication between eukaryotic cells, including transfer of biomolecules that contribute to the innate and adaptive immune response. However, if and how viruses affect gap junction intercellular communication (GJIC) remains largely unexplored. Here, we describe how the alphaherpesvirus pseudorabies virus (PRV) triggers ERK1/2-mediated phosphorylation of the main gap junction component connexin 43 (Cx43) and closure of GJIC, which depends on the viral protein pUL46.
