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...

BACKGROUND: Most exercise interventions for stroke survivors are designed for those who have substantial motor and functional disabilities. There remains a group of well-recovered stroke survivors who have yet to be investigated in terms of their physical capacity and fitness levels. OBJECTIVE: To assess and compare the physical capacities of independently ambulant, community-dwelling stroke survivors to age- and gender-matched comparison participants. METHODS: Data were obtained from 17 stroke survivors participating in the How FITSS? Trial, all with functional ambulatory category of ≥4 and a self-selected walking speed ≥0...

INTRODUCTION: Both sleep-disordered breathing (SDB) and high blood pressure (BP) occur more frequently among obese children than among normal weight children, and this may be due to endothelial dysfunction and worsened arterial stiffness. The aim of this study was to evaluate the possible association between SDB and BP, and the possible role of endothelial function and local and systemic arterial stiffness in a sample of obese children asymptomatic for sleep disturbances. MATERIALS AND METHODS: Thirty-nine obese children were included in the study...

Background. The STOP-BANG questionnaire has been used to identify surgical patients at risk for undiagnosed obstructive sleep apnea (OSA) by classifying patients as low risk (LR) if STOP-BANG score < 3 or high risk (HR) if STOP-BANG score ≥ 3. Few studies have examined whether postoperative complications are increased in HR patients and none have been described in oncologic patients. Objective. This retrospective study examined if HR patients experience increased complications evidenced by an increased length of stay (LOS) in the postanesthesia care unit (PACU)...

One bout of aerobic exercise and regular participation in aerobic exercise has been shown to result in a lowering of office and ambulatory blood pressure of hypertensive individuals. Higher-intensity aerobic exercise, up to 70% of maximal oxygen consumption, does not produce a greater hypotensive effect, compared with moderate-intensity aerobic exercise. Intermittent aerobic and anaerobic exercise, however, performed at an intensity >70% of maximal oxygen uptake has been shown to significantly reduce office and ambulatory blood pressure of hypertensive individuals...

UNLABELLED: "Non-delivery" home oxygen technologies that allow self-filling of ambulatory oxygen cylinders are emerging. They can offer a relatively unlimited supply of ambulatory oxygen in suitably assessed people who require long-term oxygen therapy (LTOT), providing they can use these systems safely and effectively. This allows users to be self-sufficient and facilitates longer periods of time away from home. The evolution and evidence base of this technology is reported with the experience of a national service review in Scotland (UK)...

BACKGROUND: A large subgroup of people with interstitial lung disease (ILD) are normoxic at rest, but rapidly desaturate on exertion. This can limit exercise capacity and worsen dyspnoea. The use of ambulatory or short-burst oxygen when mobilising or during other activities, may improve exercise capacity and relieve dyspnoea. OBJECTIVES: To determine the effects of ambulatory and short-burst oxygen therapy, separately, on exercise capacity, dyspnoea and quality of life in people who have interstitial lung disease (ILD), particularly those with idiopathic pulmonary fibrosis (IPF)...

Extracorporeal membrane oxygenation (ECMO) is a modified form of cardiopulmonary bypass. Although early trials were plagued by severe bleeding and high rates of death, subsequent experience with neonates found good survival, and ECMO became an important tool in the care of critically ill infants with respiratory failure. Since the 1980s, expansion to other groups (children, patients with cardiac disease, etc) followed as experience was obtained. Today, there is a rapid growth of ECMO, especially in the adult population...
