AIMS Erythropoiesis is a tightly controlled biological event, but its regulation under non-hypoxic conditions, however, remains unresolved. We examined whether acute changes in central venous blood pressure (CVP) elicited by whole-body tilting affect erythropoietin (EPO) concentration according to volume-regulating hormones. METHODS Plasma EPO,(More)
AIM To examine the influence of polypharmacy ordered by the pretreating site and deprescribing (i.e. the appropriate withdrawal of prescribed drugs) by the nursing home physician on survival time. METHODS Retrospective Analysis of medical databasis from 1,249 patients, thereof 611 in a nursing home with practice of deprescribing. RESULTS 70% of the(More)
In 1983 the Greek Ministry of Health, in presenting the new mental health law, described the state of the mental health system in the country as follows: "it is generally recognised that the psychiatric services in Greece are totally inadequate. The treatment inflicted on patients is often approaching the negation of the fundamental notions of human(More)
This study aimed at comparing the perception and production of English front vowels by 17 proficient Brazilian speakers of English as a second language (L2) and 6 native speakers of American English. Towards this end, three experiments were carried out: (i) a production test measuring the first two formants of the participants' English front vowels, (ii) an(More)
BACKGROUND It remains unknown whether brain perfusion is preserved and mirrored by middle cerebral blood flow velocity (MCA BFV) during prolonged changes in body posture. Herein, we examined the impact of sustained (180 min) 30° head-up (HUT) and head-down (HDT) tilt on brain perfusion, as determined by MCA BFV and blood flow in the extracranial arteries.(More)
The main aim of the present study was to quantify the magnitude of differences introduced when estimating a given blood volume compartment (e.g. plasma volume) through the direct determination of another compartment (e.g. red cell volume) by multiplication of venous haematocrit and/or haemoglobin concentration. However, since whole body haematocrit is(More)
