BACKGROUND: Osteoarthritis is a significant burden on personal health and for social cost, and its prevalence is rising. Recent research has revealed an association between osteoarthritis and cardiovascular disease, and this study uses the Framingham risk score (FRS), which is widely used as a composite index of cardiovascular risk factors, to investigate the association between osteoarthritis and various cardiovascular risk factors. METHODS: A total 9,514 participants aged 50 years or older who received knee X-ray diagnosis of the 5th Korean National Health and Nutrition Examination Survey (total surveyees = 24,173) released by the Korean Centers for Disease Control and Prevention was included for analysis...

This investigation examined the effects of slope of the surface of support (35°, 30°, 20°, 10° Facing(Toe) Down, 0° Flat and 10°, 20°, 25° Facing (Toe) Up) and postural orientation on the margins of postural stability in quiet standing of young adults. The findings showed that the center of pressure-CoP (displacement, area and length) had least motion at the baseline (0° Flat) platform condition that progressively increased as a function of platform angle in both facing up and down directions. The virtual time to collision (VTC) dynamics revealed that the spatio-temporal margins to the functional stability boundary were progressively smaller and the VTC time series also more regular (SampEn-Sample Entropy) as slope angle increased...

The lack of adherence to treatment in hypertension affects approximately 30 % of patients. The elderly, those with several co-morbidities, social isolation, low incomes or depressive symptoms are the most vulnerable to this problem. There is no ideal method to quantify the adherence to the treatment. Indirect methods are recommended in clinical practice. Any intervention strategy should not blame the patient and try a collaborative approach. It is recommended to involve the patient in decision-making. The clinical interview style must be patient-centered including motivational techniques...

The speed of sound and attenuation are important properties for characterizing reference materials such as biological phantoms used in ultrasound applications. There are many publications on the manufacture of ultrasonic phantoms and the characterization of their properties. However, few studies have applied the principles of metrology, such as the expression of the uncertainty of measurement. The objective of this study is to validate a method for characterizing the speed of sound and the attenuation coefficient of tissue-mimicking material (TMM) based on the expression of the measurement of uncertainty...

Purpose: The advent of vascular endothelial VEGF antagonists has increased the therapeutic options for diabetic maculopathy considerably. However, there is a need to identify patients who respond favorably to the treatment from those in whom the treatment is less effective. The purpose of the present study was to test the hypothesis that the oxygen saturation in retinal vessels together with other risk factors can predict the effect of anti-VEGF treatment on diabetic maculopathy. Methods: In 73 eyes from 53 patients with center-involving diabetic macular edema, multiple linear regression was used to evaluate the predictive value of oxygen saturation in larger retinal vessels together with age, diabetes duration, diabetes type, hemoglobin A1c (HbA1c), mean arterial blood pressure (MAP), body mass index (BMI), previous retinal photocoagulation, visual acuity (VA), and central retinal thickness (CRT) before treatment as explanatory variables for VA and CRT after three monthly injections of anti-VEGF medication...

BACKGROUND/AIMS: Portal hypertension (PH) is a common complication of chronic liver disease and results in esophageal and gastric variceal bleeding, which is associated with a high mortality rate. Measurement of the hepatic venous pressure gradient (HVPG) is considered the gold standard for diagnosing PH and estimating the risk of varices and bleeding. In contrast, upper gastrointestinal (GI) endoscopy (UGE) can reliably demonstrate the presence of varices and bleeding. Both measures are invasive, and HVPG is mainly restricted to tertiary centers...

The aim of this systematic review with meta-analysis was to investigate if using textured or other types of stimulating insoles improve gait characteristics and balance/postural control in patients with multiple sclerosis and Parkinson's disease. Primary outcomes for balance were the center of pressure (CoP) displacement and CoP velocity/sway rate. Primary outcomes for gait were the cadence, velocity, and step length. Standardized mean differences (SMD) were used to verify the efficacy of wearing the insoles on gait and balance outcome measures...

Big data indicates the large and ever-increasing volumes of data adhere to the following 4Vs: volume (ever-increasing amount), velocity (quickly generated), variety (many different types), veracity (from trustable sources). The last decade has seen huge advances in the amount of data we routinely generate and collect in pretty much everything we do, as well as our ability to use technology to analyze and understand it. The routine operation of modern health care systems also produces an abundance of electronically stored data on an ongoing basis as a byproduct of clinical practice...

OBJECTIVE: Primary aldosteronism is associated with increased left ventricular mass independent of blood pressure levels. Previous studies suggest that elevated aldosterone causes cardiac damage only in the presence of an inappropriate salt status. We examined the relevance of dietary salt intake on cardiac changes in patients with primary aldosteronism before and after treatment. DESIGN AND METHOD: Sixty-five patients with tumoral or idiopathic primary aldosteronism were recruited at a University medical center and followed after either surgical (n = 30) or medical (n = 35) treatment...

OBJECTIVE: Chronic kidney disease (CKD) is associated with increased arterial stiffness, which is a well-known predictor of future cardiovascular events. However, the underlying mechanism of arterial stiffening in CKD is not well known. Accelerated immune aging, characterized by expansion of immunosenescent T cell fraction might be involved in the pathogenesis of arterial stiffening in CKD. We aimed to evaluate the relationship between arterial stiffness and immunosenescent T cell (CD8CD57 or CD8CD28 T cell) fraction in patients with CKD...

Primary aldosteronism (PA) involves more than 11% of patients referred to specialized hypertension centers and, therefore, is much more common than commonly held. Moreover, it causes a damage to the heart, blood vessels and kidneys, which translates into a high rate of cardiovascular events, in excess to the degree of blood pressure raise. Along with the notion that a timely diagnosis entails a fundamental step for the choice of an appropriate therapy, which can correct the arterial hypertension and the hypokalemia, this justifies efforts to search for PA in the majority of the patients with hypertension...
