BACKGROUND: Aerobic exercise reduces blood pressure (BP) on average 5-7 mmHg among those with hypertension; limited evidence suggests similar or even greater BP benefits may result from isometric handgrip (IHG) resistance exercise. METHOD: We conducted a randomized controlled trial investigating the antihypertensive effects of an acute bout of aerobic compared with IHG exercise in the same individuals. Middle-aged adults (n = 27) with prehypertension and obesity randomly completed three experiments: aerobic (60% peak oxygen uptake, 30 min); IHG (30% maximum voluntary contraction, 4 × 2 min bilateral); and nonexercise control...

BACKGROUND: Inadequate nutritional status has been linked to poor outcomes in patients with heart failure (HF). Skeletal muscle wasting affects about 20% of ambulatory patients with HF. The impact of nutritional intake and appetite on skeletal muscle wasting has not been investigated so far. We sought to investigate the impact of nutritional status on muscle wasting and mortality in ambulatory patients with HF. METHODS: We studied 130 ambulatory patients with HF who were recruited as a part of the Studies Investigating Co-morbidities Aggravating Heart Failure (SICA-HF) program...

BACKGROUND: Arterial oxygen desaturation frequently occurs in patients with COPD during daily activities at home. Oxygen flow is usually set at fixed and low rates for ambulatory patients. We evaluated an innovative closed-loop system (FreeO2) that automatically adjusts the oxygen flow to the patient's needs in subjects with COPD during walking followed by recovery time, such as during ambulatory conditions. METHODS: Patients with COPD who exhibited oxygen desaturation on exertion were included in the study...

Motion and noise artifacts (MNAs) impose limits on the usability of the photoplethysmogram (PPG), particularly in the context of ambulatory monitoring. MNAs can distort PPG, causing erroneous estimation of physiological parameters such as heart rate (HR) and arterial oxygen saturation (SpO2). In this study we present a novel approach, "TifMA," based on using the Time-frequency spectrum of PPG to first detect the MNA-corrupted data and next discard the non-usable part of the corrupted data. The term "non-usable" refers to segments of PPG data from which the HR signal cannot be recovered accurately...

The nitrate-nitrite-nitric oxide pathway has emerged as a significant source of nitric oxide (NO) bioactivity. Dietary intake of inorganic nitrate has a number of cardiovascular effects as well as a decrease in oxygen cost during exercise and a reduction in resting metabolic rate (RMR). Oral bacteria have a key role in bioactivation of inorganic nitrate since they catalyse the conversion of salivary nitrate to the more reactive nitrite anion. Recent studies demonstrate that blood pressure increases with the use of an antiseptic mouthwash, indicating that endogenous, NO-synthase derived nitrate is recycled into nitrite and NO, sufficiently to modulate cardiovascular function...

OBJECTIVE: Loss of the nocturnal blood pressure (BP) drop is a risk factor for cardiovascular outcomes. However, clinical parameters that predispose to changes in nocturnal BP are currently uncertain. Given the possible involvement of salt sensitivity in nocturnal BP levels, we investigated a hypothesized association between plasma B-type natriuretic peptide (BNP) levels - a marker of body fluid retention - and nocturnal BP in a general population. METHODS: Study participants were 1020 general individuals...

OBJECTIVE: The most common complications of hyperbaric oxygen treatment (HBOT) are related to pressure changes on gas-containing cavities. Therefore, inability to auto-inflate the middle ear may result in transient or permanent hearing loss. However, it seems that middle ear barotrauma (MEBt) does not develop more often in mechanically ventilated patients than in ambulatory patients. This might be explained by deep sedation of these patients. Therefore, the aim of this study was to determine whether anaesthesia and/or neuromuscular blockade can influence Eustachian tube (ET) function...

AIMS/HYPOTHESIS: Gestational diabetes mellitus (GDM) is a risk factor for the development of endothelial dysfunction and cardiovascular disease. However, in vivo microvascular endothelial function in GDM has not been investigated. This study aimed to examine, using near-infrared spectroscopy (NIRS), whether: (1) there are differences in microvascular reactivity and skeletal muscle oxygen consumption (m[Formula: see text]) at rest and during exercise between GDM and uncomplicated pregnancies; and (2) there is an association of NIRS indices with macrovascular function and cardiovascular disease risk factors...

OBJECTIVE: Evaluations of physical fitness and efficiency to wheelchair propulsion are common in rehabilitation center. The multistage field test (MFT) was developed for wheelchair users and predicts the peak value of oxygen consumption [Formula: see text] , independently of their impairment [1]. In an earlier study, we did not find significant difference between VO2peak estimated by the Vanderthommen's formula and measured VO2peak [2] of trained wheelchair basketball players. MATERIAL/PATIENTS AND METHODS: Comparatively to wheelchair basketball, the athlete's cardio-respiratory and muscular limitations are greater higher in wheelchair rugby...

Veno-venous extracorporeal membrane oxygenation (ECMO) has become a viable and increasingly utilized option for the treatment of refractory hypoxemia in severe acute respiratory distress syndrome (ARDS). However, options are limited for ARDS patients who fail to wean from ECMO. The high rates of infection, presence of extrapulmonary end organ damage, ICU-acquired weakness, and high short-term mortality associated with ARDS are all significant hurdles that make lung transplantation a difficult prospect to consider...
