Part 1 of the analysis involved subjects who have been randomly assigned to get VX-770 every 12 hours at doses of 25, 75, or 150 mg or placebo. The study drug was administered during two 14-day intervals separated by a washout period. Part 2 of the analysis involved new topics who were randomly assigned to get VX-770 every 12 hours at a dosage of 150 or 250 mg or placebo for 28 consecutive days. The primary objective was to judge the adverse-event and safety profile of VX-770. Secondary end points included assessment of biomarkers of CFTR ion-channel function, pulmonary function, and health-related standard of living. The CFTR chloride transport function was evaluated in the airway epithelium based on the nasal potential difference11 and outside the respiratory tract on the basis of the sweat chloride focus.12 Each CFQ-R domain is scored on a 100-point scale, with higher scores indicating a lower effect of symptoms on the patient’s standard of living.But sleep deprivation fogs the brain, a problem that can lead to serious medical mistakes. Therefore in 2003, the Accreditation Council for Graduate Medical Education released the first caps. Before then, residents in a few specialties could average 110 hours a week. The government asked the IOM to study the current caps. Violations of current limits are normal and residents complain seldom, the committee found. While quality of life has improved, there’s still a lot of burnout. And despite one study that found residents made more mistakes while working longer shifts, patient basic safety depends on so many factors that it is impossible to tell however if the caps helped that issue, the report said.
