Comparison of Serum Selenium Levels Between Patients with Newly Diagnosed Atrial Fibrillation and Normal Controls
Biol Trace Elem Res. 2022 May 9. doi: 10.1007/s12011-022-03281-9. Online ahead of print.ABSTRACTAtrial fibrillation (AF) is the most common sustained dysrhythmia in the elderly population. It is estimated to affect more than 30 million people worldwide. AF occurs when abnormal electrical impulses start to activate in the atria and override the heart's natural pacemaker, which can no longer control the heart's rhythm. Since atrial contractility is impaired in AF, blood flow in the atria becomes stasis over time and causes thrombus formation. This thrombus causes the risk of embolism and causes complications such as stroke. ...

Mechanisms of Arsenic Exposure-Induced Hypertension and Atherosclerosis: an Updated Overview
Biol Trace Elem Res. 2022 Feb 15. doi: 10.1007/s12011-022-03153-2. Online ahead of print.ABSTRACTArsenic is an abundant element in the earth's crust. In the environment and within the human body, this toxic element can be found in both organic and inorganic forms. Chronic exposure to arsenic can predispose humans to cardiovascular diseases including hypertension, stroke, atherosclerosis, and blackfoot disease. Oxidative damage induced by reactive oxygen species is a major player in arsenic-induced toxicity, and it can affect genes expression, inflammatory responses, and/or nitric oxide homeostasis. Exposure to arsenic in d...

A community-based study of demographics, medical and psychiatric conditions, and gender dysphoria/incongruence treatment in transgender/gender diverse individuals
ConclusionTransgender and gender diverse individuals represent a population who express various gender identities and are seeking gender-specific healthcare at increasing rates. Psychiatric illness is highly prevalent compared to the US population but there is no difference in the prevalence of CV risk factors including obesity, type 2 diabetes, hypertension, and dyslipidemia.

Androgens ’ effects on cerebrovascular function in health and disease
AbstractAndrogens affect the cerebral vasculature and may contribute to sex differences in cerebrovascular diseases. Men are at a greater risk for stroke and vascular contributions to cognitive impairment and dementia (VCID) compared to women throughout much of the lifespan. The cerebral vasculature is a target for direct androgen actions, as it expresses several sex steroid receptors and metabolizing enzymes. Androgens ’ actions on the cerebral vasculature are complex, as they have been shown to have both protective and detrimental effects, depending on factors such as age, dose, and disease state. When administered chr...

Serum Ceruloplasmin Is the Candidate Predictive Biomarker for Acute Aortic Dissection and Is Related to Thrombosed False Lumen: a Propensity Score-Matched Observational Case-Control Study.
Abstract Acute aortic dissection (AAD), one of the fatal diseases observed at the department of vascular surgery, is associated with a great mortality rate at the early stage. Ceruloplasmin (CP) is the plasma protein that functions as a copper transporter. The current retrospective research was carried out to assess CP contents and to examine the possible part in diagnosing patients with AAD. In addition, propensity score matching (PSM) was also utilized for reducing the bias in case screening as well as the clinical confounders. Using PSM, this study included 85 pairs of AAD cases (Stanford A and B dissection) an...

Ectopic TWEAKR expression in type I fiber of stroke-prone spontaneously hypertensive rats is related to slow muscle-specific hypotrophy
In this study, we aimed to investigate the pathophysiological characteristics of muscle hypotrophy in SHRSP to determine the therapeutic target molecule(s).Main methodsThe difference in skeletal muscles in the lower leg between WKY and SHRSP was evaluated mainly through weight/tibial length, histological, gene expression, and protein expression analyses.Key findingsSHRSP had a significantly lower weight/tibial length in soleus and gastrocnemius, but not in plantaris and tibialis anterior, indicating that muscles consisting of a relatively high amount of slow muscle fiber were affected. This result was confirmed by the hist...

Sex-specific association of metabolic risk factors with brain ischemic lesions by severity and location
ConclusionsMetabolic syndrome was associated with brain ischemic lesions in men but not in women. Higher body mass index was related to ischemic lesions located in lobar in men and in deep brain/infratentorial areas in women. Its mechanisms remain to be further investigated.

An intricate interaction: dietary fatty acid intake influences hypertension risk
(Kanazawa University) Hypertension is an important public health problem that can lead to life-threatening cardiovascular events, including heart attack and stroke. Here, the relationship between dietary intake of n-6 fatty acids and hypertension, using blood pressure measurement and a diet history questionnaire. A Kanazawa University research team found that increased dietary intake of n-6 fatty acids positively impacted hypertension, but that this benefit was limited to individuals without impaired glucose tolerance.
