Oral HIV test almost as accurate as blood test

New findings that a saliva-based HIV test is only 2 percent less accurate than blood tests could make a case for more widespread self-testing around the world.

Researchers from McGill University in Montreal report in this week's issue of The Lancet Infectious Diseases that field research data from five worldwide databases show that in high-risk populations, the saliva test (approved by the Food and Drug Administration in 2004) is 98.0 percent accurate, compared to a blood test's 99.68 percent accuracy.

The painless and noninvasive OraQuick HIV-1/2 saliva test, which yields results in just 20 minutes, … Read more

Withings looks to create a new market with smart baby scale

LAS VEGAS--The days of standing on a scale with your baby and then without it and measuring the difference are over--if it's worth spending $150 on an Internet-connected scale built just for your little one.

So hopes Withings, the French design company that introduced a smart baby monitor last year and is unveiling its Smart Baby Scale--coming in the second quarter of 2012--at CES this week. Made for iPod, iPhone, and iPad, the scale is the first to use Wi-Fi, Bluetooth, and Bluetooth Smart connectivity for tracking the weight of babies and toddlers.

The specs: at 3.3 … Read more

About to be taken off life support, man wakes

A young man in a coma was unwittingly poised to give the ultimate this holiday season--his life, and with it, his organs. Instead, his mother became the recipient of the ultimate gift: his sudden recovery.

"Nobody could ever give me a better Christmas present than this--ever, ever, ever," his mother, Susan Regan, told ABC News this week.

Sam Schmid, a junior at the University of Arizona, suffered severe brain damage and broken femurs in a five-car accident in October that killed his friend and roommate.

ABC reports that Schmid was airlifted to the Barrow Neurological Institute in Phoenix, … Read more

Uber-app Macaw to watch those fitness goals like a hawk

Developed by U.S. Preventive Medicine alongside wireless health network provider Qualcomm Life, design firm Fjord (… Read more

Biologists one step closer to neutralizing HIV

Researchers around the world have been studying a group of recently-identified antibodies capable of neutralizing most strains of HIV, with the hopes of developing a vaccine that produces antibodies with these same properties.

Now, biologists out of the California Institute of Technology--led by Nobel Laureate David Baltimore--are one step closer to a vaccine with their new method of delivering these antibodies to lab mice, thereby protecting them from HIV.

Their approach, called Vectored ImmunoProphylaxis (VIP) and outlined in today's online issue of Nature, turns the traditional vaccination method on its head.

For the most part, researchers have focused … Read more

Will it be a C-section? Childbirth simulator helps predict

Traditionally, doctors and midwives have used a technique called pelvimetry to measure the pelvis and try to determine its adequacy for giving birth. But pelvis size is just one factor in how smoothly labor will go, rendering the method largely insufficient.

Scientists in France have been working to take some of the guesswork out of labor predictions. Today, at the Radiological Society of North America's annual meeting, they are presenting results of a study showing that their newly developed software, called Predibirth, predicts birth outcomes quite accurately.

The researchers used their software to process magnetic resonance images of 24 … Read more

Seeking weight-loss counseling? Pick up the phone

Obesity is a growing problem in the U.S. Just this week, researchers at the American Heart Association projected that by 2020, the vast majority of Americans will be overweight or obese, with more than half of the country either diabetic or pre-diabetic.

Amidst all the bad news, however, researchers at Johns Hopkins University are offering a small ray of light. Their recent study on telephone counseling by health coaches finds it to be just as effective a means of losing weight as more traditional in-person programs.

That's particularly important because in-person programs are, by nature, more time-consuming and … Read more

Online calculator helps screen for cancer early

A nonprofit research database system called QResearch--which already screens for heart disease, kidney disease, and serious blood cots--is now introducing what look to be highly accurate lung and gastroesophageal cancer screenings as well.

The University of Nottingham and ClinRisk researchers behind the computer-based tool say that their findings, published this week in the British Journal of General Practice, indicate that 10 percent of the patients predicted to be most at risk of developing one of the cancers accounted for 77 percent of actual cancer diagnoses over the following two years.

Chair of the Royal College of General Practitioners Dr. … Read more

Introducing our dirtiest public objects

Poor mail carriers. Not only do they have to put up with threatening dogs and foul weather, but they spend their days touching what may be one of our dirtiest everyday objects: mailbox handles.

The only worse offender? Gas pump handles.

So says a new study by researchers at hygiene solutions firm Kimberly-Clark Professional, who took more than 350 swabs from a variety of everyday objects in Atlanta, Chicago, Dallas, Los Angeles, Miami, and Philadelphia to measure ATP (Adenosine Triphosphate) levels commonly used to detect contamination.

While they did not distinguish between contamination types (i.e. molds versus bacteria), they … Read more

Tablets, apps help autistic people communicate

As a companion piece to an interview this evening with Steve Jobs biographer Walter Isaacson, CBS' "60 Minutes" focused on how touch-screen tablet computers--like those introduced by Apple--are helping non-verbal autistic children communicate with their parents.

The app used by one autistic person in the segment is Proloquo2Go. It's marketed to the parents of kids with special needs--specifically those with autism, apraxia, and other disabilities that affect their communication. Proloque2Go is just one of a growing number of apps that supplement existing speech or replace speech that is not functional to improve social interaction, school performance, and … Read more
