Our goal was to determine whether existing tests of spatial ability can predict an astronaut's qualification test performance after robotic training. Because training astronauts to be qualified robotics operators is so long and expensive, NASA is interested in tools that can predict robotics performance before training begins. Currently, the Astronaut(More)
BACKGROUND To determine incidence rate, etiology and risk factors for central venous catheter (CVC)-related infections in critically-ill patients, a prospective cohort study was conducted in the general Intensive Care Unit (ICU) of a 212 bed Hospital in Florianópolis, Brazil.

BACKGROUND It is still unknown whether a correlation exists between left ventricular Tei index obtained by tissue Doppler imaging and that determined by flow Doppler waveforms. This study was conducted to evaluate their relationship and to assess the positional effect on them. METHODS Twenty-six healthy subjects and 25 patients with essential hypertension(More)
Crewmember adapted to the microgravity state may need to egress the vehicle within a few minutes for safety and operational reasons after g-transitions. The transition from one sensorimotor state to another consists of two main mechanisms: strategic and plastic-adaptive and have been demonstrated in astronauts returning after long duration space flight.(More)
