The aim of this study was to measure the efficacy of a positional therapy device (PTD) at reducing proton pump inhibitor (PPI) refractory nocturnal GERD symptoms. Among patients with GERD, nocturnal symptoms are very common. A recent study demonstrated a decrease in nocturnal acid exposure and reflux episodes in healthy volunteers who slept using a PTD. This is a single-center prospective trial...
Several studies have identified obesity as a risk factor for asthma in both children and adults. An increased prevalence of asthma in subjects with gastro-oesophageal reflux (GOR) and obstructive sleep apnoea syndrome has also been reported. The aim of this investigation was to study obesity, nocturnal GOR and snoring as independent risk factors for onset of asthma and respiratory symptoms in a...
PURPOSE The use of desmopressin in patients with primary nocturnal enuresis is based on the hypothesis of a nocturnal lack of endogenous arginine vasopressin. However, in addition to the kidney, other targets of desmopressin are known. Therefore, we examined whether the administration of desmopressin influences central nervous function in children with primary nocturnal enuresis. MATERIALS AN...
OBJECTIVE Although the association between alanine aminotransferase (ALT) levels and risk of type 2 diabetes is well-studied, the effects of slightly increased ALT levels within the normal range on the temporal normal glucose profile remains poorly understood. METHODS A total of 322 Chinese subjects without impaired glucose tolerance or previous diagnoses of diabetes were recruited for study ...
While color vision perception is thought to be adaptively correlated with foraging efficiency for diurnal mammals, those that forage exclusively at night may not need color vision nor have the capacity for it. Indeed, although the basic condition for mammals is dichromacy, diverse nocturnal mammals have only monochromatic vision, resulting from functional loss of the short-wavelength sensitive ...
INTRODUCTION We investigated the correlation between systolic and diastolic nocturnal blood pressure (BP) values and office BP values, as well as parameters of 24-hour ambulatory BP monitoring, in patients with hypertension. In addition, we compared nocturnal hypertensives with nocturnal normotensives regarding their demographic, clinical, and laboratory characteristics, as well as other data f...
Nocturnal oxygen desaturation during the sleep is very frequent in patients affected by chronic obstructive pulmonary disease (COPD). Hypoventilation, rather than sleeping apnea, is commonly considered as the most relevant factor in the onset of nocturnal oxygen desaturation. On this topic, the Authors have carried on a study on the nocturnal hypoxemia in 70 hospitalized COPD patients with a me...
—Nocturnal activity is important for many animals, but difficulty in documenting that activity has hampered efforts to understand factors that influence when animals are active at night. We used automated radiotelemetry to provide the first detailed tests of the hypothesis that the nocturnal activity of free-ranging snakes should be influenced by temperature, moon phase, and prey abundance by u...
1. To clarify the relationship between nocturnal oxygen desaturation and erythropoietin production in patients with chronic obstructive pulmonary disease, we determined arterial oxygen saturation and serum immunoreactive erythropoietin levels over 24 h in eight patients with chronic obstructive pulmonary disease and in nine normal subjects. 2. In the normal subjects, there was a significant cir...
The effects of performing video display terminal (VDT) tasks with a bright display (BD) at night on nocturnal salivary melatonin concentration, rectal temperature, heart rate, and sleepiness were examined. Seven healthy male adults performed exciting VDT tasks with a BD and a dark display (DD) and boring VDT tasks with a BD and a DD from 2300 to 0200. The light intensities of the BD and DD were...
