Preeclampsia (PE) and vascular dysfunction are major causes of maternal and neonatal morbidity and mortality. Although extensively studied, the complete understanding of the pathophysiology behind PE remains unclear. Current reports indicate that exosomes are essential mediators in PE-related cardiovascular disease (CVDs). Exosomes are synthesized from multivesicular bodies (MVB) and contain functionally active microRNAs miRNAs). These miRNAs have been shown to mediate physiological and pathological functions through autocrine, paracrine, and endocrine signaling mechanisms. The role of miRNAs in pregnant women with PE has been studied extensively. However, little is known about the effect of exosomal miRNAs (exomiR) in PE. This paper will review and discuss the existing evidence for exomiR function in PE and highlight the need for future studies to explore the role that exomiR signatures have in cardiovascular dysfunction associated with PE.

Background: Genetic modifiers are believed to play an important role in the onset and severity of polycystic kidney disease (PKD), but identifying these modifiers has been challenging due to the lack of effective methodologies.
Methods: We generated zebrafish mutants of IFT140, a skeletal ciliopathy gene and newly identified autosomal dominant PKD (ADPKD) gene, to examine skeletal development and kidney cyst formation in larval and juvenile mutants. Additionally, we utilized ift140 crispants, generated through efficient microhomology-mediated end joining (MMEJ)-based genome editing, to compare phenotypes with mutants and conduct a pilot genetic modifier screen.

Background: Lower extremity arterial disease is a prevalent vascular condition leading to ischemic symptoms and increased risk of cardiovascular events. Drug-eluting stents have improved outcomes by reducing restenosis, with sirolimus emerging as a promising alternative to paclitaxel due to its safer profile. This study evaluates the efficacy and safety of novel polymer-free Amphilimus formulation (Sirolimus + fatty acid) eluting self-expanding stent in the treatment of femoropopliteal disease in a real-world population.

Importance: Previous data suggest that the time changes associated with daylight savings time (DST) may be associated with an increased incidence of acute myocardial infarction (AMI).
Objective: To determine whether the incidence of patients presenting with AMI is greater during the weeks during or after DST and compare the in-hospital clinical events between the week before DST and after DST.
Design, Setting, And Participants: This cross-sectional study examined patients enrolled in the Chest Pain MI Registry from 2013 to 2022.

Importance: As obesity rates rise in the US, managing associated metabolic comorbidities presents a growing burden to the health care system. While bariatric surgery has shown promise in mitigating established metabolic conditions, no large studies have quantified the risk of developing major obesity-related comorbidities after bariatric surgery.
Objective: To identify common metabolic phenotypes for patients eligible for bariatric surgery and to estimate crude and adjusted incidence rates of additional metabolic comorbidities associated with bariatric surgery compared with weight management program (WMP) alone.

In cardiovascular research, melatonin has shown promise in exhibiting antifibrotic properties and modulating endoplasmic reticulum (ER) stress. However, the exact mechanism by which it influences myocardial fibrosis has not been fully clarified. Therefore, this research aimed to investigate the inhibitory effect of melatonin on the progression of myocardial fibrosis through a mechanism involving the BIP/PERK/CHOP signaling pathway, both in silico and in vivo experimental models.
