Presynaptic gating of monkey proprioceptive signals for proper motor action.

Our rich behavioural repertoire is supported by complicated synaptic connectivity in the central nervous system, which must be modulated to prevent behavioural control from being overwhelmed. For this modulation, presynaptic inhibition is an efficient mechanism because it can gate specific synaptic input without interfering with main circuit operations. Previously, we reported the task-dependent presynaptic inhibition of the cutaneous afferent input to the spinal cord in behaving monkeys.

Real-World Effectiveness and Safety of a Single-Pill Combination of Olmesartan/Amlodipine/Hydrochlorothiazide in Korean Patients with Hypertension and Cardiovascular Risk Factors.

Introduction: Patients with hypertension and additional cardiovascular risk factors pose a challenge by requiring more intensive blood pressure (BP) control. Single-pill combination (SPC) therapy can benefit these patients by improving medication adherence.

Methods: This prospective, multicenter observational study assessed the real-world safety and effectiveness of an SPC containing olmesartan, amlodipine, and hydrochlorothiazide (O/A/H) in South Korean patients with hypertension and cardiovascular risk factors.

Stem cell laden nano and micro collagen/PLGA bimodal fibrous patches for myocardial regeneration.

Background: Although the use of cardiac patches is still controversial, cardiac patch has the significance in the field of the tissue engineered cardiac regeneration because it overcomes several shortcomings of intra-myocardial injection by providing a template for cells to form a cohesive sheet. So far, fibrous scaffolds fabricated using electrospinning technique have been increasingly explored for preparation of cardiac patches. One of the problems with the use of electrospinning is that nanofibrous structures hardly allow the infiltration of cells for development of 3D tissue construct.

Gender-specific differences in central blood pressure and optimal target blood pressure based on the prediction of cardiovascular events.

Background: Hypertension (HBP) is a common disease among both men and women. Central blood pressure (CBP) is a method of evaluating aorta pressure that can assess the intrinsic BP of an individual patient that more closely correlates with cardiovascular disease (CVD) outcomes than peripheral BP parameters. We evaluated gender-specific differences in CBP and optimal target BP based on a composite outcome of CVD, heart failure (HF), and hypertensive complications in patients with HBP.

Impact of hypoglycemia at the time of hospitalization for heart failure from emergency department on major adverse cardiovascular events in patients with and without type 2 diabetes.

Background: Few studies have examined the association between hypoglycemic episodes among people with type 2 diabetes (T2DM) at the time of hospitalization for heart failure (HF) and cardiovascular outcomes.

Methods: From March 2016 to June 2018, we conducted a retrospective cohort study to investigate hypoglycemia during HF hospitalization in the emergency department, three-point major adverse cardiovascular events (3P-MACE), and all-cause mortality; these were followed up through June 2021. HF hospitalization was defined according to American Heart Association criteria.

Prediction of cardiovascular events by central blood pressure using radial tonometry in type 2 diabetes mellitus patients.

Background: High blood pressure (BP) and type 2 diabetes mellitus (T2DM) are major causes of atherosclerotic cardiovascular disease (ASCVD) and heart failure (HF). Central blood pressure (CBP) is more predictive of ASCVD than is brachial BP; however, an association of CBP with ASCVD has not been found in T2DM patients. We evaluated the impact of CBP and the association between optimal level of noninvasively measured CBP and office BP in T2DM patients based on composite outcome of ASCVD, HF, and complications of hypertension.

Clinical implications of central blood pressure measured by radial tonometry and automated office blood pressure measured using automatic devices in cardiovascular diseases.

Objective: Central aortic systolic blood pressure (CBP) measured by carotid-femoral pulse wave analysis (cfPWA) is a gold standard method to estimate true arterial pressure. However, the impact of the CBP level measured by radial PWA on cardiovascular (CV) risk assessment is unclear. This study aimed to determine the impact on CV outcome assessment and the association between the optimal levels of non-invasively measured CBP and automated office blood pressure (OBP) in clinical practice.

A Prospective Randomized, Double-Blind, Multi-Center, Phase III Clinical Trial Evaluating the Efficacy and Safety of Olmesartan/Amlodipine plus Rosuvastatin Combination Treatment in Patients with Concomitant Hypertension and Dyslipidemia: A LEISURE Study.

Background: This study was a multicenter, randomized, double-blinded, placebo-controlled phase III clinical trial to investigate the efficacy and safety of an olmesartan/amlodipine single pill plus rosuvastatin combination treatment for patients with concomitant hypertension and dyslipidemia.

Methods: Patients with both hypertension and dyslipidemia aged 20-80 were enrolled from 36 tertiary hospitals in Korea from January 2017 to April 2018. Patients were randomized to three groups in a 1:1:0.

Effect of Long-Term Classical Ballet Dance Training on Postactivation Depression of the Soleus Hoffmann-Reflex.

Classical ballet dancing is a good model for studying the long-term activity-dependent plasticity of the central nervous system in humans, as it requires unique ankle movements to maintain ballet postures. The purpose of this study was to investigate whether postactivation depression is changed through long-term specific motor training. Eight ballet dancers and eight sedentary subjects participated in this study.

Real-world evidence on the strategy of olmesartan-based triple single-pill combination in Korean hypertensive patients: a prospective, multicenter, observational study (RESOLVE-PRO).

Background: In this prospective, multicenter, non-comparative observational study, the effectiveness and safety of the triple single-pill combination (SPC) of olmesartan/amlodipine/hydrochlorothiazide (OM/AML/HCTZ) were evaluated in a real clinical practice setting in Korean patients with essential hypertension.

Methods: A total of 3752 patients were enrolled and followed for 12 months after administration of OM/AML/HCTZ. Primary endpoint was change from baseline to month 6 in the mean systolic blood pressure (SBP).

Accelerated diastolic dysfunction in premenopausal women with rheumatoid arthritis.

Background: Disturbances of diastolic function precede systolic heart failure and, although clinically silent, represent the earliest sign of cardiac involvement. Diastolic dysfunction (DD) is associated with age, gender (female), and hypertension. However, little is known about the age-specific incidence rates and risk factors for DD in patients with rheumatoid arthritis (RA).

Single-pill Combination Therapy of Azilsartan Medoxomil/Chlorthalidone for Treatment of Hypertension: A Systematic Review.

Purpose: The goal of this study was to review recent clinical studies of azilsartan medoxomil (AZL-M) and chlorthalidone (CLD), a combined angiotensin receptor blocker and thiazide-like diuretic, and its role in recently published guidelines. This review explores the role of AZL-M/CLD in treating patients with hypertension.

Methods: A systematic review of literature published from 1990 to 2018 was performed by using the following key words: Edarbyclor, azilsartan, chlorthalidone, pharmacokinetic, and hypertension.

The long-term effect of age on cardiovascular disease in patients with breast cancer who received chemotherapy.

Purpose: As breast cancer survival has significantly improved and patient life expectancy has increased, greater numbers of elderly breast cancer survivors are at risk for cardiovascular disease (CVD). Therefore, this study investigated the impact of age on the incidence, mortality, and predictors of CVD following adjuvant chemotherapy in the late period of survivorship.

Methods: 761 Patients who underwent chemotherapy were enrolled and divided into patients aged < 50 years (n = 413, 54.

Acquisition and maintenance of motor memory through specific motor practice over the long term as revealed by stretch reflex responses in older ballet dancers.

The present study addressed whether motor memory acquired earlier in life through specific training can be maintained through later life with further training. To this end, the present study focused on the training effect of a specific ballet practice and investigated the spinally mediated stretch reflex responses of the soleus muscle in ballet dancers of upper-middle to old age (60.6 ± 5.

Right Ventricular Analysis Using Real-time Three-dimensional Echocardiography for Preload Dependency.

Background: The importance of the right ventricle (RV) has been increasingly recognized, and accurate RV measurement has become necessary. However, assessment of the RV with two-dimensional (2D) echocardiography has several limitations. As the development of novel methods for RV measurement continues, we can expect more accordant values related to RV geometry.

A Case of a 50-Year-Old Woman with Typical Fabry Disease Who Showed Serial Electrocardiographic and Echocardiographic Changes over a 17-Year Period.

Fabry disease (FD) is a progressive, X-linked lysosomal storage disorder caused by a deficiency of -galactosidase A activity. Affected individuals accumulate globotriaosylceramide and glycosphingolipids in the lysosomes and cytoplasm of cells throughout the body, leading to major organ failure and premature death. Cardiac involvement includes left ventricular hypertrophy, arrhythmia, endothelial dysfunction at vascular wall, and cardiomyopathy.

Association of the plasma aldosterone concentration, left atrial deformation and ambulatory blood pressure in never-treated early hypertensive patients.

Left atrial (LA) strain is known to exhibit an early progressive reduction in hypertensive patients with diastolic dysfunction. However, an association of the renin-angiotensin-*aldosterone system (RAAS) with LA deformation has not been found in these patients. We aimed to investigate the association of plasma aldosterone concentration (PAC) and 24-hour ambulatory blood pressure monitoring (ABPM) with LA and left ventricle (LV) deformation in never-treated early hypertensive patients.

The impact of preload on 3-dimensional deformation parameters: principal strain, twist and torsion.

Background: Strain analysis is feasible using three-dimensional (3D) echocardiography. This approach provides various parameters based on speckle tracking analysis from one full-volume image of the left ventricle; however, evidence for its volume independence is still lacking.

Methods: Fifty-eight subjects who were examined by transthoracic echocardiography immediately before and after hemodialysis (HD) were enrolled.

Identification of a Novel GLA Mutation (L206 P) in a Patient with Fabry Disease.

We report a new α-Galactosidase A (αGal-A) mutation in a 39-year-old Korean born, male Fabry disease patient. Fabry disease is a devastating, progressive inborn error of metabolism caused by X-linked genetic mutations. In this case, the first clinical symptom to occur was in childhood consisting of a burning pain originating in the extremities then radiating inwards to the limbs.

Is Carotid Artery Ultrasound Still Useful Method for Evaluation of Atherosclerosis?

Carotid ultrasound is an imaging modality that allows non-invasive assessment of vascular anatomy and function. Carotid intima-media thickness (IMT) has been shown to predict cardiovascular (CV) risk in multiple large studies. However, in 2013, American College of Cardiology/American Heart Association guidelines designated that the carotid IMT as class III evidence level was not recommended for use in clinical practice as a routine measurement of risk assessment for a first atherosclerotic CV event.

Findings of Cardiac Magnetic Resonance Imaging in Hypertrophic Cardiomyopathy after 16 Years.

A 58-year-old man had been diagnosed with non-obstructive hypertrophic cardiomyopathy (HCMP) according to echocardiography findings 16 years ago. Echocardiography showed ischemic cardiomyopathy (CMP)-like features with decreased systolic function but a non-dilated chamber. Coronary angiography was performed but showed a normal coronary artery.

The Clinical Significance of Separate Measurements of Carotid Arterial Wall to Assess the Risk Factor for Atherosclerosis.

Background: Carotid intima-media thickness (CIMT) is associated with several risk factors for atherosclerosis and has been consistently linked to cardiovascular and cerebrovascular disease. The clinical significance of separate measurements of CIMT, which is the sum of the intima (IT) and media thickness (MT), to use as an assessment of risk for atherosclerosis has not yet been fully established.

Methods: Among 3377 patients who underwent B-mode ultrasound of carotid arteries and coronary angiography in the Medical Department of St.
