Background: Cardiovascular diseases (CVDs) are a group of disorders of the heart and blood vessels. Yoga is a low-cost, easily accessible lifestyle modification program that holds as an approach to decreasing cardiometabolic risk factors and increasing exercise self-efficacy among high-risk subjects. This study aimed to assess the impact of the yogic lifestyle (including diet) on cardiovascular risk scores by using the Framingham (FRS), QRISK3 score, and World Health Organization (WHO) CVD risk prediction charts at baseline, three months, and six months.

Objective: Detecting and measuring changes in longitudinal fundus imaging is key to monitoring disease progression in chronic ophthalmic diseases, such as glaucoma and macular degeneration. Clinicians assess changes in disease status by either independently reviewing or manually juxtaposing longitudinally acquired color fundus photos (CFPs). Distinguishing variations in image acquisition due to camera orientation, zoom, and exposure from true disease-related changes can be challenging.

A Multifaceted Approach to Abdominal Aortic Aneurysm.

Ann Vasc Dis

January 2025

Department of Vascular Surgery, The University of Tokyo, Tokyo, Japan.

Article Synopsis
  • The exact causes of abdominal aortic aneurysms (AAAs) are still unclear, prompting the need for a thorough research approach due to their complex development.
  • Throughout my studies, I created a rat model to investigate AAAs while exploring nanoparticle drug delivery methods.
  • Although endovascular aneurysm repair (EVAR) has improved over the years, there's a lack of concrete evidence in Japan, which we aimed to address by analyzing data from multiple registries and using simulations to tackle clinical questions.

Chronic limb-threatening ischemia (CLTI) occurs in the advanced stage of peripheral artery disease and is associated with high risks of mortality and amputation. Universal management strategies are not always applicable, owing to population diversity, and the Western trials may not be applicable to Japanese patients, owing to differences in demographics and clinical profiles. This paper examines the outcomes of revascularization in Japanese CLTI patients and emphasizes the benefits of tailored management.

Surgical thrombectomy has been established as an effective treatment for acute limb ischemia (ALI). Nevertheless, manipulation via the common femoral artery (CFA) to retrieve thrombus in the infra-popliteal artery sometimes proves less effective. We retrospectively reviewed patients undergoing surgical thrombectomy for infra-inguinal ALI from January 2010 to December 2022.

Article Synopsis
  • The study explores the unclear mechanisms behind abdominal aortic aneurysm (AAA) by analyzing gut microbiota in fecal samples from patients with AAA and healthy controls.
  • It was found that patients with AAA had higher levels of certain oral bacteria and lower levels of bacterial genes associated with alpha lipoic acid (ALA) biosynthesis in their feces.
  • These findings suggest potential for developing gut microbiome-based treatments for AAA, highlighting the role of gut bacteria in the condition's pathophysiology.

Position in proton Bragg curve influences DNA damage complexity and survival in head and neck cancer cells.

Clin Transl Radiat Oncol

March 2025

Department of Molecular Genetics, Oncode Institute, Erasmus MC Cancer Institute, Erasmus University Medical Center, Rotterdam, the Netherlands.

Background And Purpose: Understanding the cellular and molecular effect of proton radiation, particularly the increased DNA damage complexity at the distal end of the Bragg curve, is current topic of investigation. This work aims to study clonogenic survival and DNA damage foci kinetics of a head and neck squamous cell carcinoma cell line at various positions along a double passively scattered Bragg curve. Complementary studies are conducted to gain insights into the link between cell survival variations, experimentally yielded foci and the number and complexity of double strand breaks (DSBs).

Objective: Antithrombotic therapy improves endovascular intervention outcomes for peripheral artery disease. However, there are limited data guiding the choice and duration of these adjuvant therapies. Thus, we explored current antithrombotic prescribing preferences among vascular interventionalists, hypothesizing that there are varied and inconsistent treatment practices among providers.

Millions of patients and their caretakers live and deal with the devastating consequences of spinal cord injury (SCI) worldwide. Despite outstanding advances in the field to both understand and tackle these pathologies, a cure for SCI patients, with their peculiar characteristics, is still a mirage. One of the most promising therapeutic strategies to date for these patients involves the use of epidural electrical stimulation.

Anisotropic structure of nanofiber hydrogel accelerates diabetic wound healing via triadic synergy of immune-angiogenic-neurogenic microenvironments.

State Key Laboratory of New Ceramics and Fine Processing, Key Laboratory of Advanced Materials, School of Materials Science and Engineering, Tsinghua University, 100084, Beijing, China.

Wound healing in chronic diabetic patients remains challenging due to the multiple types of cellular dysfunction and the impairment of multidimensional microenvironments. The physical signals of structural anisotropy offer significant potential for orchestrating multicellular regulation through physical contact and cellular mechanosensing pathways, irrespective of cell type. In this study, we developed a highly oriented anisotropic nanofiber hydrogel designed to provide directional guidance for cellular extension and cytoskeletal organization, thereby achieving pronounced multicellular modulation, including shape-induced polarization of macrophages, morphogenetic maturation of Schwann cells, oriented extracellular matrix (ECM) deposition by fibroblasts, and enhanced vascularization by endothelial cells.

Background: Although Amyloid-beta and Tau are the hallmarks of Alzheimer's Disease (AD), other protein pathways such as endothelial dysfunction may be involved and may precede cognitive symptoms. Our objective was to characterize the cerebrospinal fluid (CSF) proteomic profiles focusing on cardiometabolic-related protein pathways in individuals on the AD spectrum.

Methods: We performed CSF and plasma-targeted proteomics (276 proteins) from 354 participants of the Brain Stress Hypertension and Aging Program (BSHARP), of which 8% had preclinical AD, and 24% had MCI due to AD.

Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory vascular disease of medium-sized arteries that causes abnormal cellular growth in arterial walls and most commonly affects young to middle-aged women (20-50 years of age). While FMD often involves the renal arteries, it can affect any arterial bed. FMD has a characteristic angiographic appearance of a "string of beads.

Predictive value of CT-based and AI-reconstructed 3D-TAPSE in patients undergoing transcatheter tricuspid valve repair.

Front Cardiovasc Med

January 2025

Clinic for General and Interventional Cardiology/Angiology, Herz- und Diabeteszentrum, NRW, Ruhr-Universität Bochum, Medizinische Fakultät OWL (Universität Bielefeld), Bad Oeynhausen, Germany.

Background: The tricuspid annular plane systolic excursion (TAPSE) assessed by echocardiography has failed in predicting outcomes in patients with severe tricuspid regurgitation (TR) undergoing transcatheter tricuspid valve intervention (TTVI). Considering the complex shape of the tricuspid annulus and right ventricle, as well as the difficult echocardiographic image acquisition of the right heart, cardiac computed tomography (CT) might be superior for the analysis of the annular excursion. Thus, this study aimed to analyze whether CT-captured TAPSE provides additional value in predicting outcomes after TTVI.

The gradually increasing age of the world population implies that the prevalence of neurodegenerative diseases also continues to rise. These diseases are characterized by a progressive loss of cognitive and motor functions. Parkinson's disease, which involves the gradual death of specialized neural tissue, is a striking example of a neurodegenerative process.

Background And Objective: Hemodynamic changes that lead to increased blood pressure represent the main drivers of organ damage in hypertension. Prolonged increases to blood pressure can lead to vascular remodeling, which also affects vascular hemodynamics during the pathogenesis of hypertension. Exercise is beneficial for relieving hypertension, however the mechanistic link between exercise training and how it influences hemodynamics in the context of hypertension is not well understood.
