More Than 8 Hours" Sleep

Although the dangers of too little sleep are widely known， new research suggests that people who sleep too much may also suffer the consequences.

Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep， as well as a number of other sleep problems， than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night"s sleep than 8-hour sleepers.

These findings， which DL Daniel Kripke reported in the journal Psychosomatic Medicine，demonstrate that people who want to get a good night"s rest may not need to set aside more than 8 hours a night. He added that "it might be a good idea" for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed， but cautioned that more research is needed to confirm this.

Previous studies have shown the potential dangers of chronic shortages of sleep—— for instance，one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.

For the current report， Kripke reviewed the responses of 1，004 adults to sleep questionnaires，in which participants indicated how much they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night， arising early in the morning and being unable to fall back to sleep， and having fatigue interfere with day-to-day functioning.

Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview， Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence， he added that one way to help insomnia is to spend less time in bed. "It stands to reason that if a person spends too long a time in bed， then they"ll spend a higher percentage of time awake." he said.

Cancer Drug Trials Often Halted Early

An increasing number of clinical trials for new cancer treatments are being halted before the risks and benefits have been fully evaluated， say Italian researchers， who warn that this growing trend could put patients at risk of harm from new therapies rushed into use.

The researchers looked at 25 randomized， controlled clinical trials that were stopped early because the treatments had started to show benefit to patients.

"When we analyzed 25 trials over a 10-year period between 1997 and 2007， we found a consistent increase in prematurely stopped trials——more than 50 percent were stopped within the last three years，" study co-author Giovanni Apolone said at a news conference Tuesday.

Of 14 trials halted early and published between 2005 and 2007， the researchers found that 11（79 percent） of them were used to support drug approval applications submitted to the European Medicines Agency and the U.S. Food and Drug Administration.

"This suggests a strong commercial component in stopping trials prematurely. In fact， this strategy could guarantee quicker access to the market for companies. On the other hand， a quicker clinical drug development may lead to an "immature" benefit/risk balance of new drugs，"Apolone said.

He and his colleagues "are aware that trials stopped early because they are showing benefit may result in identification of promising new treatments for patients. However， findings obtained following this strategy should be considered to be preliminary results that require subsequent confmnation."

It can take several years for the long-term benefits or harmful side effects of a new treatment to become apparent， Apolone noted， but the average duration （持续时间） of the 25 studies he and his colleagues analyzed was 30 months， with a range from 12 to 64 months.

They also found that at the time five of the studies were stopped， they"d enrolled less than 40 percent of the total number of patients planned for final analysis.

"Clinical trials need to stop early for superior benefit whenever there"s proof beyond reasonable doubt that the new treatment really is superior. That would be an ethical obligation，"Stuart Pocock， a professor of medical statistics at the London School of Hygiene and Tropical Medicine in the United Kingdom， said at the news conference. "However， too many trials are stopped early claiming efficacy （功效） without strong evidence being available."

The number of prematurely stopped clinical trials has increased recently. 查看材料
