Failure Of Latest HIV Vaccine Test: A 'Huge Disappointment'

Originally published on Fri April 26, 2013 12:14 pm

The largest current study of an AIDS vaccine, involving 2,500 people, is being stopped.

After an oversight committee took a preliminary peek at the results this past Monday, they concluded there was no way the study would show that the vaccine prevents HIV infection.

Nor would the vaccine suppress the wily virus among people who get infected despite being vaccinated.

The work is only in mice so far, but it sure is intriguing.

A newly found hormone revs up production of cells that make insulin — the very kind that people with advanced diabetes lack.

An international dream team of flu experts assembled in China today.

Underscoring the urgency that public health agencies feel about the emergence of a new kind of bird flu, the team is headed by Dr. Keiji Fukuda, the World Health Organization's top influenza scientist.

Before he left Geneva, Fukuda explained the wide-open nature of the investigation in an interview with NPR.

Explosions At Boston Marathon

Boston Doctors Compare Marathon Bomb Injuries To War Wounds

Originally published on Wed April 17, 2013 10:26 am

Medical personnel work outside the medical tent in the aftermath of two explosions near the finish line of the Boston Marathon on Monday. At area hospitals, doctors say they were confronted with the kinds of injuries U.S. troops get in Iraq and Afghanistan.

Boston hospitals always staff up their emergency rooms on Marathon Day to care for runners with cramps, dehydration and the occasional heart attack.

But Monday, those hospitals suddenly found themselves with more than 100 traumatized patients — many of them with the kinds of injuries seen more often on a battlefield than a marathon.

Like most big-city hospitals these days, Tufts Medical Center runs regular disaster drills, featuring simulated patients smeared with fake blood.

Feds Fault Preemie Researchers For Ethical Lapses

Originally published on Thu April 11, 2013 8:04 am

How much oxygen should severely premature infants receive? A study that sought to answer the question has been criticized for not fully informing parents about the risks to their children.

Federal officials say a large study of premature infants was ethically flawed because doctors didn't inform the babies' parents about increased risks of blindness, brain damage and death.

The study involved more than 1,300 severely premature infants at nearly two dozen medical institutions between 2004 and 2009. The infants were randomly assigned to receive two different levels of oxygen to see which was better at preventing blindness without increasing the risk of neurologic damage or death.

Human Cases Of Bird Flu In China Draw Scrutiny

Sixteen cases of a new flu around Shanghai have touched off a major effort to determine what kind of threat this new bug might be.

The victims range in age from 4 to 87 years old. Six have died. It is a tragedy for them and their families, but is it a global crisis?

To understand why so few cases are generating so much concern, the first thing to know is that no flu virus like this one — called H7N9 — has ever been known to infect humans before.

As Stroke Risk Rises Among Younger Adults, So Does Early Death

Most people (including a lot of doctors) think of a stroke as something that happens to old people. But the rate is increasing among those in their 50s, 40s and even younger.

In one recent 10-year period, the rate of strokes in Americans younger than 55 went up 84 percent among whites and 54 percent among blacks. One in 5 strokes now occurs in adults 20 to 55 years old — up from 1 in 8 in the mid-1990s.

Catalog Of Gene Markers For Some Cancers Doubles In Size

The largest gene-probing study ever done has fished out dozens of new genetic markers that flag a person's susceptibility to breast, ovarian and prostate cancer.

The 74 newly discovered genetic variants double the previously known number for these malignancies, all of which are driven by sex hormones.

Underscoring the sheer magnitude of the findings, they're contained in 15 scientific papers published simultaneously by five different journals. The Nature group of journals has collected them all here.

Mammography outcomes from nearly a million U.S. women suggest which ones under 50 would stand the greatest chance of benefiting from regular screening: those with very dense breasts.

That's been a bone of contention ever since a federal task force declared nearly four years ago that women younger than 50 shouldn't routinely get the test.

Nothing sends more kids to the hospital than asthma.

So when doctors at Children's Hospital in Boston noticed they kept seeing an unusually high number of asthmatic kids from certain low-income neighborhoods, they wondered if they could do something about the environment these kids were living in.

Every day something like 550 hospitalized Americans suffer cardiac arrest. That's bad news. Only about one in five will live to leave the hospital.

But for the lucky 44,000 a year who are resuscitated and survive, the outlook is much better than expected, authors of a new study say.

It's not the first study that finds the lowly aspirin may protect against the deadliest kind of skin cancer, but it is one of the largest.

And it adds to a mounting pile of studies suggesting that cheap, common aspirin lowers the risk of many cancers — of the colon, breast, esophagus, stomach, prostate, bladder and ovary.
