Privacy Worry May Keep HIV Patients from Therapy
Patients infected with HIV are often concerned about2 the confidentiality of their HIV-positive status. In fact, some patients are so worried that they will actually give up treatment to prevent the release of this information, according to a report published in the August issue of AIDS Care.
Dr. Kathryn Whetten-Goldstein and colleagues from Duke University, Durham, North Carolina3,
studied the confidentiality issues of 15 HIV-infected patients from rural North Carolina locations. They were divided into groups designed to explore their attitudes toward, and experiences with, breaches in confidentiality.
“The fear of a breach in confidentiality is definitely affecting the care that HIV-infected patients
receive,” Whetten-Goldstein said. “Most studied patients had experienced or knew someone who had experienced a breach in confidentiality.”
“Two types of breaches occurred,”Whetten-Goldstein noted. “The first was a more obvious type of breach. One example was a nurse who told her child that her patient was HIV-positive out of concern that her child would play with the patient’s child.4”
“The other type of breach was more subtle, one that providers might not consider breaches, 5”
Whetten-Goldstein explained. “This type of breach involves providers talking about a patient’s HIV status without the patient’s knowledge of the interaction.”
“The law allows the sharing of information between providers within the same institution, but patient’s consent must be obtained before providers at different institutions can share information,” she pointed out. “Patients in the study wanted providers to tell them when they are going to share information with other providers and why it is being done,” Whetten-Goldstein said. “They also felt that providers should be punished when a breach occurs.”
“However, because patients are often reluctant to seek legal action which may further expose their status, they felt that the system should regulate itself,” she added.

Food and Cancer
Medical expels have suspected for many years that there is a strong link between what a person eats and cancer. They say a new study provides the first evidence1 that vitamins could reduce a person’s chance of developing cancer. A team of Chinese and American scientists did the study. They are from American
National Cancer Institute2 and the Cancer Institute of the Chinese Academy of Medical Sciences3 in Beijing. The Journal of the National Cancer Institute published the results of the study. About thirty thousand people between the ages of 40 to 69 took part in the study. They were from the northern central Chinese area of Linxian. Most of them took vitamins and minerals every day for five years.
Linxian was chosen because the people there have all extremely high rate of cancer of stomach and
esophagus. Researchers believe that fungus and molds in local foods may be partly responsible for the high cancer rate. Researchers divided those into eight groups. Seven of the groups received different mixtures of vitamins and minerals daily. The amounts of the vitamins and minerals were 1 to 2 times greater than what American health officials say is needed. The eighth group received sugar pills4 that had no effect. Those who seemed to gain the most received a mixture of a form of vitamin A called β–carotene, vitamin E and the mineral selenium. The vitamin and mineral are believed to prevent damage to cells caused by cancer-causing substances. Researchers reported a 13 percent drop in cancer rates in those who took β–carotene, vitamin E and selenium5. They also found a 10 percent drop in the number of deaths caused by strokes from bursting blood vessels.
Scientists warn that it is too soon to know if the effect would be the same among people in other
countries. They note that the people in Linxian eat foods that lack necessary vitamins and minerals. Chinese officials will continue to record the health records of the people in Linxian for many years. For now officials reportedly are considering using the results of the study. They want to find a way to improve the health of people in Linxian and other small towns in China. 练习:

Stomach Ulcer
Stomach ulcers are the cause of severe pain for many people. Doctors have been able to help lessen the pain of ulcers. They could not cure them. Now doctors have discovered a cause of ulcers. This means they may have found a way to cure people who suffer from the stomach pain. Studies show that ten percent of the population will develop an ulcer at some time in their life. So a possible cure is good news for many people.
Ulcers are wounds in the stomach that are similar to small cuts or tears1. These wounds can harm the tissue in the stomach2，the pipe that carries the food to the stomach or parts of the small intestines. Fluids in the stomach then increase the pain of an ulcer. How does a person know he or she has an ulcer? Doctors say most people with ulcers feel a burning pain in their chest or stomach3. This pain often is called heartburn. It usually happens before eating or during the night. It causes some people to lose their desire to eat, or they are unable to keep food in their stomachs. Doctors believed that ulcers were caused by unusually strong stomach fluids, which damaged stomach tissue. Now they have discovered that most ulcers are caused by a bacterial organism called Hillico Bactor Pilorie or H Pilorie. H Pilorie bacteria are what make stomach produce extra stomach fluid. Doctors found that they can kill the bacteria with medicines called antibiotics. Health experts say the discovery of a cure for ulcers can save thousands of millions of dollars in medical costs. They also believe curing ulcers will reduce the number of people who develop stomach cancer. The number of people with stomach cancer is very high in Japan, Southeast Asia and parts of Africa.
Doctors say a person is more likely to get an ulcer if someone in his or her family has had one. In fact a person with the family history of ulcers is three times more likely to get one than other people. There are ways people can protect themselves from developing an ulcer. Doctors say it is more important to reduce the amount of strong fluids in the stomach. To do this, doctors say, people should not smoke cigarettes or drink alcohol. And they say people should reduce tension in their lives.

What Is a Dream?
For centuries, people have wondered about the strange things that they dream about. Some psychologists say that this nighttime activity of the mind has no special meaning. Others，however， think that dreams are an important part of our lives. In fact, many experts believe that dreams can tell us about a person’s mind and emotions.
Before modern times, many people thought that dreams contained messages from God. It was only in the twentieth century that people started to study dreams in a scientific way.
The Austrian psychologist, Sigmund Freud1，was probably the first person to study dreams scientifically. In his famous book, The interpretation of Dreams (1900), Freud wrote that dreams are an expression of a person’s wishes. He believed that dreams allow people to express the feelings, thoughts, and fears that they are afraid to express in real life.
The Swiss psychiatrist Carl Jung2 was once a student of Freud’s. Jung，however，had a different idea about dreams. Jung believed that the purpose of a dream was to communicate a message to the dreamer. He thought people could learn more about themselves by thinking about their dreams. For example, people who dream about falling may learn that they have too high an opinion of themselves. On the other hand, people who dream about being heroes may learn that they think too little of themselves.
Modern-day psychologists continue to develop theories about dreams. For example, psychologist
William Domhoff from the University of California, Santa Cruz，believes that dreams are tightly linked to a person’s daily life, thoughts, and behavior. A criminal, for example, might dream about crime.
Domhoff believes that there is a connection between dreams and age. His research shows that children do not dream as much as adults. According to Domhoff, dreaming is a mental skill that needs time to develop.
He has also found a link between dreams and gender. His studies show that the dreams of men and women are different. For example, the people in men’s dreams are often other men, and the dreams often involve fighting. This is not true of women’s dreams.3 Domhoff found this gender difference in the dreams of people from 11 cultures around the world, including both modern and traditional ones.
Can dreams help us understand ourselves? Psychologists continue to try to answer this question in
different ways. However, one thing they agree on this: If you dream that something terrible is going to occur, you shouldn’t panic. The dream may have meaning, but it does not mean that some terrible event will actually take place. It’s important to remember that the world of dreams is not the real world.

Red Meat Links to Higher Risk of Breast Cancer
Exercise and keeping a healthy weight are two things that doctors say might help women lower their risk of breast cancer.
Mothers may reduce their risk if they breastfeed for at least four months. For older women, hormone replacement therapy2 can lower the risk of some other diseases. But it has been found to increase the risk of breast cancer. So women should consider their choices carefully. The same may be said for diet.
New findings show that younger women who eat a lot of red meat have higher rates of breast cancers called hormone-receptor positive3. The growth is fed by the levels of estrogen or another hormone, progesterone, in the body.
Researchers at Brigham Women’s Hospital in Boston, Massachusetts, reported the findings as part of a health study of nurses. The researchers followed the health of more than 90,000 women from 1991 to 2003. Those who ate the most red meat ate more than one and one-half servings a day. A serving was defined as roughly 84 grams. Those who ate the least red meat ate less than three servings a week. This is what the study found about breast cancers that were hormone receptor-positive: The women who ate the most red meat were almost two times as likely to get them as the women who ate the least of it.
Eunyoung Cho, the lead author of the report, says more research is needed to know the reason for the link. But in the past, researchers have suggested that three things may play a part. One is the way meat is cooked or processed. Another is the use of growth hormones in cows. And the third is the kind of iron in red meat: The study appears in the Archives of Internal Medicine.
And now we have more to tell you about our subject — resveratrol. We discussed a study in the United States that found that large amounts of this plant compound helped fat mice live longer. The mice were fed much more resveratrol than people could get from red wine, one of the foods that contains it.
Now, scientists in France say resveratrol also improves muscle performance — again, at least in mice. They were able to run two times as far in laboratory treadmill tests4 as mice normally could. The study at the Institute of Genetics and Molecular and Cellular Biology5 appeared in the journal Cell.

2.Estrogen may contribute to the development of breast cancer as much as hormone replacement therapy.

3.The amount of red meat a woman eats is directly proportional to the probability of breast cancer. A. Right
