Objectives: Regular exercise is known to reduce arterial stiffness (AS) in hemodialysis patients. However, the impact of a more realistic intradialytic form of exercise, such as pedaling, is unclear. We aimed to examine 1) the effect of intradialytic pedaling exercise on AS over 4 months, and 2) the longer-term effect of pedaling on AS 4 months after exercise cessation. Methods: Patients on stable in-center hemodialysis (3x/week) were randomly assigned 1:1 to either intradialytic pedaling exercise (EX) or to a control group receiving usual hemodialysis (nonEX) for 4 months...

REVIEW
Stefano Salvioli, Maddalena Guidi, Giulia Marcotulli
Plantar heel pain is one of the most common causes of pain and musculoskeletal pathologies of the foot. The aim of this systematic review was to identify the most effective, conservative and non-pharmacological treatments regarding pain in patients with plantar heel pain. The authors searched 5 databases and included only randomized control trials which investigated the efficacy of a conservative non-pharmacological treatment compared to the placebo, for the outcome of pain. Study selection, data collection and risk of bias assessment were conducted independently by two authors, and consensus was reached with a third author...

BACKGROUND: Predictive abilities of cardiovascular biomarkers to renal function decline are more significant in Chinese community-dwelling population without glomerular filtration rate (GFR) below 60 ml/min/1.73m(2), and long-term prospective study is an optimal choice to explore this problem. Aim of this analysis was to observe this problem during the follow-up of 5 years. METHODS: In a large medical check-up program in Beijing, there were 948 participants with renal function evaluated at baseline and follow-up of 5 years...

BACKGROUD AND PURPOSE: Wall-to-lumen ratio of retinal arterioles (W/L ratio) might serve as an in-vivo parameter of microvascular damage. No study has investigated the relationship between carotid stiffness and W/L ratio of retinal arteries. Therefore, the aim of the current study was to assess the correlation between local carotid stiffness, as assessed by echotracking technique, and W/L ratio of retinal arterioles, as assessed by noninvasive flowmetry in normotensive patients and in patients with primary hypertension...

Background: Arterial stiffness increases pressure load to the left ventricle (LV), leading to LV hypertrophy and subendocardial ischemia. Neurohormones stimulate myocardial fibrosis and LV dysfunction. We aimed to explore the associations of arterial stiffness and plasma aldosterone with multi-directional, layer-specific LV, and left atrial (LA) mechanical function in hypertensive patients. Methods: Layer-specific LV global longitudinal strain (GLS-trans, GLS-endo, GLS-epi), global circumferential strain (GCS-trans, GCS-endo, GCS-epi), LV torsional parameters, and LA global longitudinal strain (LA GLS) were analyzed by two-dimensional speckle tracking echocardiography in 195 hypertensive patients (110 men, mean age 55 years)...

Cognitive impairment and elevated arterial stiffness have been described in patients with arterial hypertension, but their association has not been well studied. We evaluated the correlation of arterial stiffness and different cognitive domains in patients with hypertension compared with those with normotension. We evaluated 211 patients (69 with normotension and 142 with hypertension). Patients were age matched and distributed according to their blood pressure: normotension, hypertension stage 1, and hypertension stage 2...

We report on two previously unknown non-local effects that have been found to impair Brillouin optical time-domain analysis (BOTDA) sensors that deploy limited extinction ratio (ER) pump pulses. The first one originates in the increased depletion of the pedestal of the pump pulses by the amplified probe wave, which in turn entails a reduced amplification of the probe and a measurement distortion. The second effect is due to the interplay between the transient response of the erbium-doped fiber amplifiers (EDFA) that are normally deployed to amplify the pump and the pedestal of the pump pulses...

BACKGROUND: The aim of this study was to investigate the association between the serum cystatin C level and cardiovascular disease risk in patients with type 2 diabetes mellitus. METHODS: We studied 523 patients with type 2 diabetes mellitus and calculated estimated 10-year risk of atherosclerotic cardiovascular disease (%). Subclinical atherosclerosis was defined as brachial-ankle pulse wave velocity ⩾1700 ms, indicating the presence of arterial stiffness. RESULTS: Cystatin C level was significantly higher in the subclinical atherosclerosis group (brachial-ankle pulse wave velocity ⩾ 1700 ms) than in the non-subclinical atherosclerosis group (brachial-ankle pulse wave velocity < 1700 ms) (7...

BACKGROUND: Metabolic syndrome (MetS) is associated with structural and functional vascular abnormalities, which may lead to increased arterial stiffness, more frequent cardiovascular events and higher mortality. However, the role played by clustering of risk factors and the combining pattern of MetS risk factors and their association with the arterial stiffness have yet to be fully understood. Age, hypertension and diabetes mellitus seem to be strongly associated with increased pulse wave velocity (PWV)...

BACKGROUND: Peripheral arterial stiffness gives rise to the high prevalence of peripheral arterial disease (PAD). It is necessary to conduct a large-scale study in Chinese community-dwelling population to clarify the relationships of alcohol and tobacco consumption with peripheral arterial stiffness. Most studies had a small sample size, and were not performed in Chinese community-dwelling population without symptomatic PAD. This analysis was designed to examine the relationships of alcohol and tobacco consumption with peripheral arterial stiffness in Chinese community-dwelling population without symptomatic PAD...

OBJECTIVE: Arterial stiffness is an independent cardiovascular risk factor and sodium intake could be a determinant of arterial stiffness. Nevertheless, the studies that investigated the effect of reducing dietary sodium intake on arterial stiffness in humans provided inconsistent results. Therefore, we performed a systematic review and a meta-analysis of the available randomized controlled trials of salt restriction and arterial stiffness to try and achieve more definitive conclusions...

BACKGROUND: Although pulse-wave velocity (PWV) is a recognized risk predictor for cardiovascular diseases, its association with cardiovascular outcomes in heart failure with preserved left ventricular ejection fraction (HFpEF) is unclear. METHODS AND RESULTS: The 502 patients with HFpEF finally enrolled in this study (mean follow-up duration: 1017 days) were divided into those with or without peripheral artery disease (PAD). The latter were further grouped according to brachial-ankle PWV (baPWV) quintiles using an ankle-brachial pressure index device...

PURPOSE: Inhibition of the renin-angiotensin system may have effects on vascular structure and function beyond the effects on blood pressure (BP) reduction. We studied the ability of a single arm cuff oscillometric method (Arteriograph, TensioMed, Hungary) to assess effects of antihypertensive treatment on BP and arterial stiffness. Furthermore, this technique was compared to pulse wave analysis and applanation tonometry (SphygmoCor, AtCor Medical, Australia). MATERIALS AND METHODS: Brachial and aortic BP, augmentation index (AIx), and carotid-femoral pulse wave velocity (PWV) was simultaneously assessed by both techniques in 71 untreated hypertensive patients...

Asthma is a chronic airway inflammation with a potential systemic impact. Atherosclerosis is a chronic inflammatory artery disease. The aim of our study was to prove if there is a correlation between the occurrence of asthma and increased atherosclerotic vessel disorders. Vessel status was compared between mild-to-moderate, severe allergic asthma and matched controls. Measurements of artery stiffness were calculated by central pulse wave velocity, ultrasonographic strain imaging and ankle-brachial index. Atherosclerotic plaque burden was assessed by colour-coded duplex sonography...

Blunted nocturnal dipping in blood pressure (BP) is associated with increased cardiovascular disease (CVD) risk in middle-aged/older adults. The prevalence of blunted nocturnal BP dipping is higher in persons with obesity and diabetes, conditions that are also associated with elevated aortic stiffness and inflammation. Therefore, we hypothesized that elevated glycemia, inflammation and aortic stiffness would be inversely associated with the magnitude of nocturnal systolic BP dipping among middle-aged/older adults with obesity at high CVD risk...
