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.

Introduction: Early-onset Alzheimer's disease (EOAD) and late-onset Alzheimer's disease (LOAD) share similar amyloid etiology, but evidence from smaller-scale studies suggests that they manifest differently clinically. Current analyses sought to contrast the cognitive profiles of EOAD and LOAD.
Methods: Z-score cognitive-domain composites for 311 amyloid-positive sporadic EOAD and 314 amyloid-positive LOAD participants were calculated from baseline data from age-appropriate control cohorts.

Recent developments in treatments for both forms of advanced age-related macular degeneration (AMD) have led to the approval of multiple agents and modalities within the last few years. Five new medications for both neovascular AMD (nAMD) and geographic atrophy (GA) secondary to nonexudative AMD (neAMD) have been FDA-approved within the last 5 years, along with a new device designed for sustained drug delivery for nAMD. In nAMD, the newest agents approved by the FDA are brolucizumab (Novartis Pharmaceuticals, Basel, Switzerland), faricimab (F.

Background: Prevention of alcohol-exposed pregnancy (AEP) involves reducing risky alcohol consumption among women at-risk for pregnancy, using effective contraception among women drinking at risky levels to prevent pregnancy, or both. This study presents the outcomes of a randomized controlled trial assessing the efficacy of Native CHOICES, a culturally tailored adaptation of the CHOICES intervention, among American Indian/Alaska Native (AI/AN) women.
Methods: AI/AN women aged 18-44 who were at-risk for an AEP were randomly assigned in a 1:1 ratio to either the Native CHOICES intervention or a waitlist control group.

We sought to characterize cellular composition across the cardiovascular system of the healthy Wistar rat, an important model in preclinical cardiovascular research. We performed single-nucleus RNA sequencing (snRNA-seq) in 78 samples in 10 distinct regions, including the four chambers of the heart, ventricular septum, sinoatrial node, atrioventricular node, aorta, pulmonary artery, and pulmonary veins, which produced 505,835 nuclei. We identified 26 distinct cell types and additional subtypes, with different cellular composition across cardiac regions and tissue-specific transcription for each cell type.

Introduction: The clinical, research and advocacy communities for Rett syndrome are striving to achieve clinical trial readiness, including having fit-for-purpose clinical outcome assessments. This study aimed to (1) describe psychometric properties of clinical outcome assessment for Rett syndrome and (2) identify what is needed to ensure that fit-for-purpose clinical outcome assessments are available for clinical trials.
Methods: Clinical outcome assessments for the top 10 priority domains identified in the Voice of the Patient Report for Rett syndrome were compiled and available psychometric data were extracted.

Background: Initiating urate-lowering therapy can trigger gout flares. Gout flares have been associated with a temporally increased risk of cardiovascular events. Therefore, we aimed to estimate the risk of cardiovascular events in patients with gout initiating urate-lowering therapy with flare prophylaxis using colchicine (the drug recommended for gout flare prohphylaxis by many international societies) compared with no prophylaxis.

Despite landmark breakthroughs in cancer research, African American adults (AA) bear the highest cancer burden compared to other racial groups in the United States (US). AA adults have twice the likelihood of dying from prostate and uterine cancers compared to White adults, suggesting that there are fundamental issues yet to be addressed when developing and implementing cancer-preventative programs for AA communities. Community-based participatory research (CBPR) empowers community members to identify and prioritize their health problems and preferred strategies to tackle these issues.

Reducing low-density lipoprotein cholesterol (LDL-C) levels has been shown to reduce the risk of developing atherosclerotic cardiovascular disease (ASCVD). Statins are the foundation of LDL-C lowering therapy with other non-statin agents used in circumstances where goal LDL-C levels are not reached or owing to intolerance to adverse effects of statins. In 2003, the discovery of the role of the proprotein convertase subtilisin/kexin type 9 (PCSK9) system in promoting elevated LDL-C levels led to new avenues of drug development to achieve target LDL-C.

Toxicant exposure can lead to acute liver injury, characterized by hepatic reprogramming and wound healing. Hepatic stellate cells (HSC) play a key role in liver regeneration during wound healing by secreting fibrogenic factors and production of extracellular matrix (ECM). However, repetitive injury to the liver can lead to extensive scarring and liver fibrosis, indicating HSCs coordinate both regeneration and disease.

Formative verbal feedback during live surgery is essential for adjusting trainee behavior and accelerating skill acquisition. Despite its importance, understanding optimal feedback is challenging due to the difficulty of capturing and categorizing feedback at scale. We propose a Human-AI Collaborative Refinement Process that uses unsupervised machine learning (Topic Modeling) with human refinement to discover feedback categories from surgical transcripts.

Background: In the PROTECTION trial, intravenous amino acids (AA) decreased the occurrence of acute kidney injury (AKI) in cardiac surgery patients with cardiopulmonary bypass (CPB). Recruitment of renal functional reserve may be responsible for such protection. However, patients with chronic kidney disease (CKD) have diminished renal functional reserve, and AA may be less protective in such patients.

Chemical modification of RNAs is important for posttranscriptional gene regulation. The METTL3-METTL14 complex generates most -methyladenosine (mA) modifications in messenger RNAs (mRNAs), and dysregulated methyltransferase expression has been linked to cancers. Here we show that a changed sequence context for mA can promote oncogenesis.

Blood vessels permeate all organs and execute myriad roles in health and disease. Here, we present a protocol to efficiently generate human artery and vein endothelial cells (ECs) from pluripotent stem cells within 3-4 days of differentiation. We delineate how to seed human pluripotent stem cells and sequentially differentiate them into primitive streak, lateral mesoderm, and either artery or vein ECs.

Background: Early midlife individuals (ages 30-40) experience demographic shifts that may influence the remainder of adult life. Although new or persistent alcohol misuse is common during this period, early midlife is understudied in alcohol use literature. We examined the heritability of alcohol misuse; the associations between alcohol misuse and sociodemographic factors, physical health, and well-being; and whether these associations were robust in cotwin comparisons.

Deficits in IL-2 signaling can precipitate autoimmunity by altering the function and survival of FoxP3+ regulatory T cells (Tregs) while high concentrations of IL-2 fuel inflammatory responses. Recently, we showed that the non-beta IL-2 SYNTHORIN molecule SAR444336 (SAR'336) can bypass the induction of autoimmune and inflammatory responses by increasing its reliance on IL-2 receptor α chain subunit (CD25) to provide a bona fide IL-2 signal selectively to Tregs, making it an attractive approach for the control of autoimmunity. In this report, we further demonstrate that SAR'336 can support non-beta IL-2 signaling in murine Tregs and limit NK and CD8+ T cells' proliferation and function.

The adenosinergic pathway converting endogenous ATP to adenosine (ADO) is a major immunosuppressive pathway in cancer. Emerging data indicate that plasma small extracellular vesicles (sEV) express CD39 and CD73 and produce ADO. Using a noninvasive, highly sensitive newly developed assay, metabolism of N-etheno-labeled eATP, eADP or eAMP by ecto-nucleotidases on the external surface of sEV was measured using high pressure liquid chromatography with fluorescence detection.

Previous studies used mostly White samples, but Black/African Americans (B/AAs) must be included in this research to ensure reliability.
Method: Participants were B/AA consensus-confirmed healthy controls (HCs) (n = 49) or mild cognitive impairment (MCI) (n = 34) adults 60-85 years that completed NIHTB-CB and Cogstate for laptop at two timepoints within 4 months.
