Eye masks and earplugs could help hospital patients get a better night's sleep. Researchers writing in BioMed Central's open access journal Critical Care investigated their effect on sleep quality in a simulated intensive care environment.

Xiaoying Jiang from Fujian Medical University, Fuzhou, China, worked with a team of researchers to carry out the study in 14 healthy people exposed to recorded intensive care noise and equivalent light levels. She said, "Sleep disruption is common in intensive care unit patients and has been associated with impaired immune function, decreased inspiratory muscle endurance, extended mechanical ventilation, delirium and severe morbidity."

The researchers measured sleep quality over four nights; one to get used to the new environment and one 'baseline' night, followed by two nights exposed to noise and light, one with eye masks and ear plugs and one without. To minimize any effects of ordering, the last two nights were randomized. According to Jiang, "The earplugs and eye masks were applied easily and remained in place and intact throughout the nights they were used. Use of plugs and masks resulted in more REM sleep, shorter REM latency and fewer arousals. Subjective measures of sleep quality were also significantly improved, and participants reported much less awareness of their surroundings when they were worn."

Jiang concludes, "This study provides a reasonable basis for promoting the routine use of earplugs and eye masks for intensive care patients. Future studies should be designed to determine if this ultimately improves clinical outcomes."

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
