Exposure to repetitive head impacts (RHI), such as those experienced in American football, is linked to cognitive dysfunction later in life. Traumatic encephalopathy syndrome (TES) is a proposed clinical syndrome thought to be linked to neuropath-ology of chronic traumatic encephalopathy (CTE), a condition associated with RHI from football. Cognitive intra-individual variability (d-CIIV) measures test-score dispersion, indicating cognitive dysfunction.

Background: Protein-truncating mutations in the titin gene are associated with increased risk of atrial fibrillation. However, little is known about the underlying pathophysiology.

Methods: We identified a heterozygous titin truncating variant (TTNtv) in a patient with unexplained early onset atrial fibrillation and normal ventricular function.

Background: Chronic limb-threatening ischemia (CLTI) in patients with chronic kidney disease (CKD) has a high risk of poor outcomes. We aimed to compare the outcomes of lower extremity revascularization in patients with CLTI stratified by CKD severity in patients enrolled in the prospective, randomized Best Endovascular vs Best Surgical Therapy in Patients with CLTI (BEST-CLI) trial.

Methods: The BEST-CLI trial dataset was queried to categorize patients into three groups according to CKD stage.

Importance: A substantial number of individuals worldwide experience long COVID, or post-COVID condition. Other postviral and autoimmune conditions have a female predominance, but whether the same is true for long COVID, especially within different subgroups, is uncertain.

Objective: To evaluate sex differences in the risk of developing long COVID among adults with SARS-CoV-2 infection.

Improved Annotation of Asthma Gene Variants with Cell Type Deconvolution of Nasal and Lung Expression-Quantitative Trait Loci.

Am J Respir Cell Mol Biol

January 2025

University of Groningen, University Medical Center Groningen, Department of Pulmonology and Pediatric Allergy, Beatrix Children's Hospital, Groningen, Netherlands.

Asthma is a genetically complex inflammatory airway disease associated with over 200 Single nucleotide polymorphisms (SNPs). However, the functional effects of many asthma-associated SNPs in lung and airway epithelial samples are unknown. Here, we aimed to conduct expression quantitative trait loci (eQTL) analysis using a meta-analysis of nasal and lung samples.

Background: Hypertension, a leading global risk factor for mortality and disability, disproportionately affects racial and ethnic minorities. Our study investigates the association between the type of prior antihypertensive medication use and the likelihood of cardiovascular events (CVE) and assesses whether the patient's race influences this relationship.

Methods: A retrospective study of 14 836 hypertension cases aged ≥ 40 years was conducted using data from HCA Healthcare between 2017 and 2023.

 Cognitive impairment is a core feature of traumatic encephalopathy syndrome (TES), the putative clinical syndrome of chronic traumatic encephalopathy-a neuropathological disease associated with repetitive head impacts (RHI). Careful operationalization of cognitive impairment is essential to improving the diagnostic specificity and accuracy of TES criteria. We compared single- versus two-test criteria for cognitive impairment in their associations with CSF and imaging biomarkers in male former American football players.

Background: Risk estimation is an essential component of cardiovascular disease prevention among people with HIV. We aimed to characterise how well atherosclerotic cardiovascular disease (ASCVD) risk scores used in clinical guidelines perform among people with HIV globally.

Methods: In this prospective cohort study leveraging REPRIEVE data, we included participants aged 40-75 years, with low-to-moderate traditional cardiovascular risk, not taking statin therapy.

Accurately basecalling sequence backbones in the presence of nucleotide modifications remains a substantial challenge in nanopore sequencing bioinformatics. It has been extensively demonstrated that state-of-the-art basecallers are less compatible with modification-induced sequencing signals. A precise basecalling, on the other hand, serves as the prerequisite for virtually all the downstream analyses.

Background: Women with endometriosis are more likely to have migraine. The mechanisms underlying this co-morbidity are unknown. Prolactin, a neurohormone secreted and released into circulation from the anterior pituitary, can sensitize sensory neurons from female, but not male, rodents, monkeys and human donors.

Reversal of inflammatory reprogramming by vasodilator agents in pulmonary hypertension.

ERJ Open Res

January 2025

Center for Pulmonary Vascular Biology and Medicine, Pittsburgh Heart, Lung and Blood Vascular Medicine Institute, Division of Cardiology, Department of Medicine, University of Pittsburgh School of Medicine and UPMC, Pittsburgh, PA, USA.

Background: Pulmonary arterial hypertension (PAH) is a deadly disease without effective non-invasive diagnostic and prognostic testing. It remains unclear whether vasodilators reverse inflammatory activation, a part of PAH pathogenesis. Single-cell profiling of inflammatory cells in blood could clarify these PAH mechanisms.

Systematic Review and Meta-Analysis of the Super High-Pressure Balloon (SIS-OPN) for Percutaneous Coronary Intervention.

Catheter Cardiovasc Interv

January 2025

Minneapolis Heart Institute and Minneapolis Heart Institute Foundation, Abbott Northwestern Hospital, Minneapolis, Minnesota, USA.

Introduction: The super high-pressure NC balloon (OPN NC; SIS Medical AG, Winterthur, Switzerland) is increasingly used in percutaneous coronary intervention (PCI). We performed a systematic review and meta-analysis of its efficacy and safety.

Methods: A systematic review was conducted using PubMed and the Cochrane Library to identify studies using the OPN NC balloon in PCI.

Background Cardiac surgery-associated acute kidney injury (CSA-AKI) remains a significant complication following coronary artery bypass grafting (CABG), affecting 22%-30% of patients. This study evaluates the efficacy of NephroCheck, a biomarker-based test measuring insulin-like growth factor-binding protein 7 (IGFBP7) and tissue inhibitor of metalloproteinases-2 (TIMP2), in predicting postoperative AKI. Methods In this retrospective observational cohort study, 21 patients undergoing isolated CABG were analyzed.

Cheek swabs, heterogeneous samples consisting primarily of buccal epithelial cells, are widely used in pediatric DNA methylation studies and biomarker creation. However, the decrease in buccal proportion with age in adults remains unexamined in childhood. We analyzed cheek swabs from 4626 typically developing children 2-months to 20-years-old.

Maternal postpartum depressive (PPD) symptoms have the potential to negatively impact mother-infant interactions, particularly in populations experiencing contextual stress. We used a resilience perspective to examine maternal perceptions of partner support as a protective factor in the relation between PPD symptoms and mother-infant dyadic reciprocity. Low income, Mexican-origin women ( = 322; = 27.

Importance: Atrial fibrillation (AF) is the most common, chronic, cardiac arrythmia in older US adults. It is not known whether AF is independently associated with increased risk of retinal stroke (central retinal artery occlusion), a subtype of ischemic stroke that causes severely disabling visual loss in most cases and is a harbinger of further vascular events.

Objective: To determine whether there is an association between AF and retinal stroke.

Advances in modeling permeability and selectivity of the blood-brain barrier using microfluidics.

Microfluid Nanofluidics

July 2024

Department of Biomedical Engineering, The University of Arizona, 1200 E University Blvd, Tucson 85721, Arizona, USA.

The blood-brain barrier (BBB) protects the brain by actively allowing the entry of ions and nutrients while limiting the passage of from toxins and pathogens. A healthy BBB has low permeability and high selectivity to maintain normal brain functions. Increased BBB permeability can result from neurological diseases and traumatic injuries.
