单选题Privacy Worry May Keep HIV Patients from Therapy Patients infected with HIV are often concerned about 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 Carolina, 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. " "The other type of breach was more subtle, one that providers might not consider breaches, " 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.

单选题U.S. to Start $3.2 Billion Child Health Study in January A study that will cost $3.2 billion and last more than two decades to track the health of 100,000 U. S. children from before birth to age 21 will be launched in January, U. S. health officials said on Friday. Officials from the U. S. government"s National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness. The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health. Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said. Officials said more than $ 200 million has been spent already and the study is projected to cost $ 3.2 billion. "We anticipate that in the long term, what we learn from the study will result in a significant savings in the nation"s health care costs," Dr. Duane Alexander, who heads the NIH"s Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters. The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21. Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheidt of the NIH, who heads the study. The people taking part will be from rural, urban and suburban areas, from all income and educational levels and from all racial groups, the NIH said.
