Otolith tilt-translation reinterpretation following prolonged weightlessness: implications for preflight training.
Observations with three astronauts yielded two major findings. First, perceived self-motion during sinusoidal roll differed immediately postflight from preflight. ⋯ These results support an "otolith tilt-translation reinterpretation" hypothesis, which has clear implications for understanding astronaut reports of space motion sickness during the early period of orbital flight. A proposal for "prophylactic adaptation training" which may provide preflight adaptation to weightlessness, derives from this research.

To identify and characterize civilian air ambulance services, a questionnaire was mailed nationwide to 583 prospective air ambulance services, with 154 responding. Our survey identified differences between hospital, hospital-affiliated, and private air ambulance services as to aircraft ownership, availability, types of aircraft, types of patients being transported, types of medical personnel and equipment, aircraft retrofit, and their feelings regarding air ambulance regulations. ⋯ Based upon this data, we recommend that air ambulance regulations be directed at levels of patient care. Such regulations and guidelines will assist patient safety during aeromedical transports without jeopardizing currently operating air ambulance services.

Transderm scopolamine efficacy related to time of application prior to the onset of motion.
We evaluated Transdermal Scopolamine related to the time of application prior to the onset of motion. In this study 44 subjects participated. ⋯ Therefore, the transdermal scopolamine system should be applied at least 8 h before potentially disturbing motion to provide adequate prophylaxis against motion sickness. We found no significant difference in motion sickness susceptibility between men and women, in contrast to earlier reports.
