NY Subway Clear of Anthrax, Says CDC Smallpox Virus To Stay On Hand in U.S., Says Gov't Pump Iron, Dump the Cane Fifth West Nile Death Confirmed Asthmatics Need To Pull the Trigger Gout Drug Aids Heart Patients
Here are some of the latest health and medical news developments, compiled by editors of The HealthDay Service:
No Anthrax on NY Subway, Say Early Findings
Early tests on the New York City subway system indicate that it's clear of anthrax, but officials yesterday cautioned that the subway, by definition, is not a sterile environment and that final results of the subway tests will come sometime next week, according to a CNN report.
These tests are part of a weeks-long attempt to figure out how 61-year-old Kathy Nguyen, a Manhattan hospital worker, could have contracted -- and died from -- the disease.
The mail is also still getting its share of attention. Sterilizing mail to kill anthrax spores may take radiation doses so high that they will destroy ordinary medicines, according to an Associated Press interview this week with Food and Drug Administration physicist Orhan Suleiman. He is advising the Postal Service on irradiation.
But so far no one knows just what effect the 5.6 million rads of radiation, delivered by electron beam technology that is now being used on letters, will have on any medical substance. There's simply no data, according to the Pharmaceutical Research and Manufacturers Association.
So far, only letters from government buildings and post offices, known to be anthrax tainted, are being irradiated. Packages that would hold medicines have not yet been put through the process.
In the meantime, another anthrax-containing letter, this time addressed to Sen. Patrick J. Leahy of Vermont, was found Friday evening among 250 barrels of letters impounded after the initial scare, reports The New York Times. The letter was postmarked Oct. 9 in Trenton, N.J., says the FBI. It appears to be almost a carbon copy of the anthrax-containing letters sent to Senator Tom Daschle, the majority leader, and NBC news and The New York Post.
Keep Smallpox in Stock, Orders Bush Admin
The debate over whether the U.S. will destroy its stock of smallpox virus is now settled: The Centers for Disease Control and Prevention will keep it hidden but on hand in case it is needed to fend off a bioterrorist attack, according to a report from CNN.
If someone can make it into a weapon, we may need more new vaccines to deal with it, said one official. And the way to research drugs is by using the live virus.
The U.S. and Russia are the only two nations with a known stockpile of the deadly virus, but some experts are concerned that some of Russia's stock may have leaked into nations like Iraq and into terrorists' hands.
The Clinton administration was leaning toward destroying the virus. Smallpox was declared eradicated worldwide decades ago by the World Health Organization, and it was felt keeping such a virus on hand was unnecessary.
Meanwhile, a poll done for the Associated Press says that 60 percent of all Americans would want a smallpox vaccination if they could get one.
Power Lifts Lift Energy
Men in their 70s who are getting frail may recapture at least some of that youthful vigor with a regimen of power weight lifting and a bit of testosterone, says Dr. Michael O'Grady of Emory University in Atlanta in an Associated Press story.
He and his colleagues studied 32 men, whose average age was 75, had extremely low testosterone levels and were so weak they were barely able to walk around their own homes.
The researchers started the men out slowly with exercise, but by the end of a year, the men who did exercise and took the hormone had improved their performance sixfold. Some could even lift weights of 600 pounds, say the researchers.
But testosterone is not a quick fix, caution the experts. Taking it means having to be closely monitored for signs of prostate cancer.
Fifth West Nile Death Confirmed
A 44-year-old man has become the first person in Alabama to die from the West Nile virus, state health officials said this week, according to the Associated Press.
The man, who was not identified, died Oct. 30 after becoming infected in late August, state veterinarian Bill Johnston said.
The man is the fifth person in the nation to die from the mosquito-borne virus this year, following a 70-year-old man in Massachusetts, a 45-year-old man in New Jersey, a 71-year-old woman in Georgia and a Connecticut woman in her 90s.
The federal Centers for Disease Control and Prevention didn't confirm the Alabama case until this week because of a backlog caused by the anthrax investigation, Johnston said.
Asthmatics Need Mite-y Clean Environments
Ridding your home of dust mites, tobacco smoke, pet dander, molds and other asthma triggers may be a significant way to help asthmatics breathe a bit easier, say experts in a HealthDay report.
Eliminating these irritants could cut the number of asthma attacks by 60 percent, says Dr. Norman Edelman, consultant for scientific affairs with the American Lung Association.
The expert advice: No smoking in the house, be wary of contact with pets, wash all bedding, including pillow cases, once a week in water that's hotter than 130 degrees F to get rid of the mites.
Gout Drug Aids Heart Patients
A gout drug gives straining heart muscles a much-needed tune-up and could one day be a treatment for patients with heart failure, new research says, according to a HealthDay report.
Scientists have found that the drug, allopurinol, can make heart muscles run better while using less energy when it's infused directly into the organ's blood supply. Experts caution, however, that with only nine patients, the study is quite small, and that infusing the heart isn't an appropriate way to treat large numbers of people.
But, they add, the results are encouraging enough to warrant additional research into the drug as a possible therapy for heart failure, a disease with no cure that strikes 550,000 Americans a year.
