background increasing demand for limited healthcare resources raises questions about appropriate use of inpatient beds. in the first paediatric bed utilisation study at a regional university centre in ireland, we conducted a cross-sectional study to audit the utilisation of inpatient beds at the regional paediatric unit (rpu) in university hospital limerick (uhl), limerick, ireland and also exa...

Long-duration bed rest is widely employed to simulate the effects of microgravity on various physiological systems, especially for studies of bone, muscle, and the cardiovascular system. This microgravity analog is also extensively used to develop and test countermeasures to microgravity-altered adaptations to Earth gravity. Initial investigations of bone loss used horizontal bed rest with the ...

INTRODUCTION Spaceflight has profound effects on the human body. Many of these effects can be induced with head-down bed rest, which has been a useful ground-based analog. With limited resources aboard the International Space Station for human research, the bed rest analog will be a primary platform on which countermeasures will be developed and tested for lunar and Mars mission scenarios. ME...

BACKGROUND We linked extensive longitudinal data from the Swedish national eating disorders quality registers and patient registers to explore clinical characteristics at diagnosis, diagnostic flux, psychiatric comorbidity, and suicide attempts in 850 individuals diagnosed with binge-eating disorder (BED). METHOD Cases were all individuals who met criteria for BED in the quality registers (N ...

Orthostatic intolerance follows actual weightlessness and weightlessness simulated by bed rest. Orthostasis immediately after acute exercise imposes greater cardiovascular stress than orthostasis without prior exercise. We hypothesized that 5 min/day of simulated orthostasis [supine lower body negative pressure (LBNP)] immediately following LBNP exercise maintains orthostatic tolerance during b...

Leg venous hemodynamics [venous distensibility index (VDI), arterial flow index (AFI), half-emptying time (T1/2)], and leg volumes (LV) were assessed by mercury strain-gauge plethysmography with venous occlusion and volometry, respectively, in seven men before, during, and after 42 days of 6 degrees head-down bed rest. Results showed a high increase in VDI up to day 26 of bed rest (+50% vs. con...

introduction: the important of comparing performance of hospitals using hospital indicators, has been made the necessary of utilizing of the application model inevitable. this study aimed to compare hospital performance key indicators simultaneity. methods: in this descriptive cross sectional and retrospective study, 31 hospitals of isfahan university of medical sciences were evaluated in 2007....

a numerical model for two-phase debris flows is developed in this paper, on the basis of understanding of the physical characteristics of debris flows from field investigations and experiments. employing a moving coordinate, the kinetic energy equation of gravel particles in unit volume in debris flow is developed by considering the potential energy of the particles, energy from the liquid phas...
