This study examined the effects of presleep cognitive stress on insomniac and noninsomniac subjects. Ten sleep-onset insomniacs and 11 noninsomniacs spent five nights in a sleep laboratory. They slept undisturbed on the first three nights but were exposed to brief cognitive stressors before sleep-onset on the fourth and fifth nights. Significant(More)
INTRODUCTION Circulatory dysfunction in cirrhotic patients may cause a specific kind of functional renal failure termed hepato-renal syndrome (HRS). It contributes to the high incidence of renal failure in cirrhotic intensive care unit (ICU) patients. Fluid therapy may aggravate renal failure by increasing ascites and intra-abdominal pressure (IAP). This(More)
OBJECTIVE Volume depletion and/or increased hematocrit are associated with poor prognosis in necrotizing pancreatitis. Several studies suggest that intrathoracic blood volume index (ITBI) might be superior to central venous pressure (CVP) with regard to preload assessment. Therefore, the aim of our study was to evaluate the predictive value of CVP and(More)
BACKGROUND Variability of body weight (BW) and height calls for indexation of volumetric hemodynamic parameters. Extravascular lung water (EVLW) has formerly been indexed to actual BW (BW(act)) termed EVLW-index (EVLWI). In overweight patients indexation to BW(act) might inappropriately lower indexed EVLWI(act). Several studies suggest indexation of EVLWI(More)
OBJECTIVE To assess the effect of reducing intra-abdominal pressure (IAP) by paracentesis on renal resistive index (RI), hemodynamics and renal function. DESIGN AND SETTING Uncontrolled trial in a university gastroenterological intensive care unit. PATIENTS Twelve spontaneously breathing cirrhotic patients with hepatorenal syndrome, tense ascites and a(More)
— Interpretation of aerial images is normally carried out by visual interpretation as traditional classification routines are too limited in dealing with the complexity of very high resolution data. Segmentation based classifiers can overcome this limitation by dividing images into homogenous segments and using them as basis for further classification(More)
The prevalence of dementia syndromes was studied in individuals aged 70 and over living in institutions integrated into primary care within a limited area in southern Sweden. The populations studied were all persons living in homes for the elderly in the city of Lund (n = 471) and all persons living in nursing homes in the Lund health service district (n =(More)
In this study, we investigated whether hydration with sodium bicarbonate is superior to hydration with saline in addition to theophylline (both groups) in the prophylaxis of contrast-induced nephropathy (CIN). It was a prospective, randomized, double-blinded study in a university hospital on 2 general intensive care units (63% of investigations) and normal(More)
