Call it the beta-carotene quandary. Researchers are scrambling to figure out why foods rich in beta-carotene seem to reduce the risk of lung cancer while high doses of beta-carotene supplements seem to increase the risk.

One theory–that massive doses of beta-carotene keep people from absorbing other substances in fruits and vegetables that may be the real protectors–now has new support from a study from the National Cancer Institute in Bethesda, Maryland.

Regina Ziegler and co-workers analyzed the diets that 763 men recalled eating before they were diagnosed with lung cancer. She compared the diets to those of 564 similar men with no cancer.

The results: Lung cancer was more closely associated with a low intake of alpha-carotene than with a low intake of beta-carotene. Among the men who were current or recent smokers, a diet poor in beta-carotene increased the risk of lung cancer by 60 percent, while a diet poor in alpha-carotene roughly doubled the risk.

Alpha- and beta-carotene usually occur in the same foods. Only seven of the men had frequently eaten foods that are especially rich in beta-carotene (like spinach and other leafy greens) and had infrequently eaten foods that are rich in both carotenes (like carrots and sweet potatoes). All seven got lung cancer.

“It is premature to conclude that alpha-carotene is protective in humans,” says Ziegler. “The most rational way to reduce lung cancer risk is to eat a variety of vegetables and fruits and, most important, to not smoke.”

What is bradycardia?

Having bradycardia (say “bray-dee-KAR-dee-uh”) means your heart beats very slowly. For most people, a heart rate of 60 to 100 beats a minute while at rest is considered normal. If your heart beats less than 60 times a minute, your doctor may diagnose bradycardia

Aids Risk factors

Posted: 28 Dec 2010 08:23 PM PST

AIDS can be transmitted in several ways. The risk factors for HIV transmission vary according to category:

* Sexual contact. Persons at greatest risk are those who do not practice safe sex, those who are not monogamous, those who participate in anal intercourse, and those who have sex with a partner with symptoms of advanced HIV infection and/or other sexually transmitted diseases (STDs). In the United States and Europe, most cases of sexually transmitted HIV infection have resulted from homosexual contact, whereas in Africa, the disease is spread primarily through sexual intercourse among heterosexuals.
* Transmission in pregnancy. High-risk mothers include women married to bisexual men or men who have an abnormal blood condition called hemophilia and require blood transfusions, intravenous drug users, and women living in neighborhoods with a high rate of HIV infection among heterosexuals. The chances of transmitting the disease to the child are higher in women in advanced stages of the disease. Breast feeding increases the risk of transmission by 10-20%. The use of zidovudine (AZT) during pregnancy, however, can decrease the risk of transmission to the baby.
* Exposure to contaminated blood or blood products. With the introduction of blood product screening in the mid-1980s, the incidence of HIV transmission in blood transfusions has dropped to one in every 100,000 transfused. With respect to HIV transmission among drug abusers, risk increases with the duration of using injections, the frequency of needle sharing, the number of persons who share a needle, and the number of AIDS cases in the local population.
* Needle sticks among health care professionals. Present studies indicate that the risk of HIV transmission by a needle stick is about one in 250. This rate can be decreased if the injured worker is given AZT, an anti-retroviral medication, in combination with other medication.

HIV is not transmitted by handshakes or other casual non-sexual contact, coughing or sneezing, or by blood-sucking insects such as mosquitoes.
AIDS in women

AIDS in women is a serious public health concern. Women exposed to HIV infection through heterosexual contact are the most rapidly growing risk group in the United States population. The percentage of AIDS cases diagnosed in women has risen from 7% in 1985 to 23% in 1999. Women diagnosed with AIDS may not live as long as men, although the reasons for this finding are unclear.
