Article Abstract
Introduction: Poor cardiovascular health (CVH) is linked to Alzheimer's disease and dementia; however, its association with neurocognitive trajectories earlier in life remains underexplored.
Methods: We included 3224 participants with information on CVH at early midlife (mean age 45.0 ± standard deviation 3.4) an cognitive assessments, and neuroimaging 5, 10, and 15 years later including white matter hyperintensities (WMHs), total gray matter (GM), and hippocampal volume. CVH was operationalized according to the American Heart Association's (AHA) "Life's Essential 8" (LE8) guidelines. The association between LE8 and cognitive and neuroimaging measures was examined using mixed linear regression adjusting for age, sex, race, and education.
Results: Worse LE8 score was associated with steeper decline in cognition, higher accumulation of WMHs, and steeper decline in total GM and hippocampal volume.
Discussion: Poor CVH is related to accelerated brain aging across midlife, highlighting the need to screen for and improve CVH earlier to prevent adverse cognitive outcomes.
Highlights: Poor cardiovascular health in early midlife is associated with faster decline in cognition across 10 years overall and in specific domains. Poor and intermediate cardiovascular health was associated with higher accumulation of white matter hyperintensities across midlife. Poor cardiovascular health was associated with faster atrophy in total gray matter volume and hippocampal volume.

Embryo transfer (ET) is a valuable reproductive technology in pigs, albeit its efficiency remains significantly lower than that of natural mating or artificial insemination (AI), owing to high embryonic death rates. Critical for embryo survival and pregnancy success is the placenta, which supports conceptus development through nutrient exchange, hormone production, and immune modulation. Alterations in placental development and function may therefore underlie the reduced efficiency of ET.

Pomegranate (Punica granatum L) is a rich source of bioactive compounds, including punicalagin, ellagic acid, anthocyanins, and urolithins, which contribute to its broad pharmacological potential. This review summarizes evidence from in vitro and in vivo experiments, as well as clinical studies, highlighting pomegranate's therapeutic effects in inflammation, metabolic disorders, cancer, cardiovascular disease, neurodegeneration, microbial infections, and skin conditions. Mechanistic insights show modulation of pathways such as nuclear factor-kappa B (NF-κB), mitogen-activated protein kinase (MAPK), alpha serine/threonine-protein kinase (AKT1), and nuclear factor erythroid 2-related factor 2 (Nrf2).

Background And Aims: Aim of this study was to assess the risk of hemolysis, the extent of myocardial and neural injury after monopolar, monophasic pulsed field ablation (PFA) using a lattice-tip catheter in comparison to single-shot PF ablation platforms employing bipolar, biphasic waveforms.
Methods: This prospective study included consecutive patients undergoing PFA for atrial fibrillation (AF) using the Affera™ mapping and ablation system (n=40). Biomarkers for hemolysis (haptoglobin, LDH, bilirubin), myocardial injury (high-sensitive troponin T, CK, CK-MB), neurocardiac injury (S100), and renal function (creatinine) were assessed pre- and within 24 hours post-ablation.
