单选题U.S. States Do Poorly in Women"s Health Not a single U. S. state meets basic federal goals for women"s health, and the nation as a whole fails except in two areas—mammograms and dental check-ups—researchers said on Thursday. Millions of women lack health insurance, and states make it difficult to enroll in Medicaid, the state-federal health insurance plan for the poor, according to the report. And few states are doing anywhere near enough to help women quit smoking the leading cause of death in the United States. "The nation as a whole and the individual states fall short of meeting national goals," reads the report. Put together by the National Women"s Law Center and the Oregon Health Science University, "These health goals provide a road map for assessing the status of women"s health." Of 27 measures examined by the group, from screening for diseases to actually treating them, the nation passes on only two, the researchers said. "The nation is so far from the healthy people goals that it receives an overall grade of "unsatisfactory"," they wrote. The problem seems to be a lack among states of an overall plan for health in general, the NWLC said. "State policy makers" piecemeal approach to our health care crisis has resulted in a complex and ineffective system that fails to meet the health care needs of women," Judy Waxman, NWLC Vice President for Health, said in a statement. "Lawmakers need to take a comprehensive, long-term approach to meeting women"s health needs and tackle this serious problem that plagues so many families."

单选题 Late-night Drinking Coffee lovers beware. Having a quick "pick-me-up" cup of coffee1 late in the day will play havoc with your sleep. As well as being a stimulant, caffeine interrupts the flow of melatonin, the brain hormone that sends people into a sleep. Melatonin levels normally start to rise about two hours before bedtime. Levels then peak between 2 a.m. and 4 a. m. , before falling again. "It's the neurohormone that controls our sleep and tells our body when to sleep and when to wake," says Maurice Ohayon of the Stanford Sleep Epidemiology Research Center at Stanford University in California. But researchers in Israel have found that caffeinated coffee halves the body's levels of this sleep hormone. Lotan Shilo and a team at the Sapir Medical Center in Tel Aviv University found that six volunteers slept less well after a cup of caffeinated coffee than after drinking the same amount of decal. On average, subjects slept 336 minutes per night after drinking caffeinated coffee, compared with 415 minutes after decal. They also took half an hour to drop off-twice as long as usual-and jigged around in bed twice as much. In the second phase of the experiment, the researchers wolfe the volunteers every three hours and asked them to give a urine sample. Shilo measured concentrations of a breakdown product of melatonin. The results suggest that melatonin concentrations in caffeine drinkers were half those in decal drinkers. In a paper accepted for publication in Sleep Medicinc, the researchers suggest that caffeine blocks production of the enzyme that drives melatonin production. Because it can take many hours to eliminate caffeine from the body, Ohayon recommends that coffee lovers switch to decal after lunch.

单选题Smart Window Windows not only let light in to cut down an electricity use for lighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between with a flip of a switch. "It took us a long time to figure out what a window really is," says Claes Granqvist. He's a professor of solid-state physics at Uppsala University in Sweden. "It's contact with the outside world. You have to have visual contact with the surrounding world to feel well." So, windows and natural light are important for improving the way people feel when they're stuck indoors. Yet, windows are the weak link in a building when it comes to energy and temperature control. In the winter, cold air leaks in. When it's hot and sunny, sunlight streams in. All of this sunlight carries lots of heat and energy. And all of this extra heat forces people to turn on their air conditioners. Producing blasts of cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world. Windows have been a major focus of energy research for a long time. Over the years, scientists have come up with a variety of strategies for coating, glazing, and layering windows to make them more energy efficient. Smart windows go a step further. They use chromogenic technologies which involve changes of color. electro chromic windows use electricity to change color. For example, a sheet of glass coated with thin layers of chemical compound such as tungsten oxide works a bit like a battery. Tungsten oxide is clear when an electric charge is applied and dark when the charge is removed, that is, when the amount of voltage is decreased, the window darkens until it's completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear or dark. One important feature that makes a smart window so smart is that it has a sort of "memory." All it takes is a small jolt of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take anywhere from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need. "In the future," Granqvist says, "our buildings may look different.

单选题Reingold and other epidemiologists don't discount hand--washing as an important tool in public health: there is plenty of evidence that it prevents other nasty bugs, including the common cold, many respiratory (呼吸道的) infections, and viruses that cause diarrhea (腹泻). But Reingold is bothered by the lack of science supporting the CDC's message, and he worries that the emphasis on a simple measure like hand -washing creates a false sense of security from H1N1 and tamps down the discussion of more difficult preventive measures. He said as much in an e - mail to the CDC this May. "I wouldn't care so much that we might be getting folks to improve hand - washing... with what is likely to be incorrect information about its ability to prevent influenza" if the media and the court of public opinion weren't so quick to embrace it as the only solution at the expense of things like surgical masks, wrote Reingold in his letter to the CDC. While Reingold admits he doesn't know if masks would reduce transmission of the virus, he hypothesizes that they're more likely to be helpful containing exposure to the airborne virus than hand -washing, and should not be so easily discounted. (Other experts are skeptical of face masks because it's difficult to ensure proper use, or that people will wear them in the first place. ) Hand -washing can prevent some nasty bugs, but not includingA. the comnlon cold.B. respiratory infections.C. viruses causing diarrhea.D.

单选题High Rate of Stress among Doctors As the HIN1 swine flu virus spreads rapidly through the Northern Hemisphere, doctors and other health care professionals face a heavier - than - usual workload. Even without a flu pandemic, studies show, up to 60 percent of physicians in the United States suffer to some degree from" burnout" - physical and emotional exhaustion: The stress on doctors can cause medical mistakes even errors that could cost people their lives, so the universities that train America' s doctors are looking for ways to prevent burnout. At a hospital in Tennessee, Dr. William May tries to diagnose his patients as quickly as he can. "We don' t like to have to add that extra space. We' re just busy. Very, very busy, "he says. Even without a pandemic to add to the workload, doctors are busier than ever In Rochester, New York, primary -care physician Michael Schneider has seen the stress from his work increase steadily over the past 30 years. " It' s something lost when we have phones ringing, consultants calling, and computer screens flashing. "he says. Another study looks at how to help physicians cope with stress. Dr. Michael Krasner, leader of the study, saw a definite change in the doctors after a year of relaxation training. His theory is that physicians who have better communication skills, and who know how to relax when they can, can avoid symptoms of emotional exhaustion, such as a lack of a sense of accomplishment or difficulty empathizing with patients. Dr Schneider says the course helped him. "We are so removed from some of the skills we had all learned - or believed we had learned in medical school - about communication, that having an intensive course that really re-teaches and reinforces the skills that we had perhaps lost, is very valuable, "he says. This research highlights how important it is for doctors to address their own physical and mental well being, both for their own good and for that of their patients. The study appears in the journal of the American Medical Association.

单选题One Good Reason to Let Smallpox Live It"s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US and one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves? 16 reality, of course, it was naive to 17 that everyone would let 18 of such a potential weapon. Undoubtedly several nations still have 19 vials. 20 the last "official" stocks of live virus bred mistrust of the US and Russia, 21 no obvious gain. Now American researchers have 22 an animal model of the human disease, opening the 23 for tests on new treatments and vaccines. So one again there"s a good reason to 24 the virus—just in 25 the disease puts in reappearance. How do we 26 with the mistrust of the US and Russia 27 Keep the virus 28 international auspices in a well-guarded UN laboratory that"s open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn"t 29 the idea is wrong. If the virus 30 useful, then let"s make it the servant of all humanity—not just a part of it.

单选题Not only is this a deadly way to practice medicine, but it's also a breathtakingly expensive one. In 2005 Americans paid out a record 16% of our gross domestic product for health care--a cool $ 2 trillion - making US the world's top spender on health care per capita. You might think we'd be getting some bang for those bucks, but our leading killer remains what it has been every year since 1900 (with the exception of 1918, when influenza claimed more lives ): heart disease, which kills nearly 650,000 of us each year. "The reason we rank so poorly is that we don't provide a basic - wellness infrastructure, "says Dr. Mehmet Oz, director of the cardiovascular institute at the Columbia University Medical Center and a host on the Discovery Health Channel. How much did the Americans pay for health care in 2005?A. 16% of their income.B. US $ 650,000C. US $ 2 i000,000,000,000D. US $1900 to US $1918 per person.
