laron writes “In Israel, a new law is in the making: Holders of donor cards and their families would get preference if they should need an organ for themselves. Apparently this initiative faces resistance from Orthodox rabbis, who hold that organ donation is against religious law. Jacob Lavee, director of the heart transplant unit at Israel’s Sheba Medical Center, and one of the draftees of this new law, hopes that a broader pool of organs will ultimately benefit everyone, but acknowledges that one of his primary motivations is ‘to prevent free riders.’ (Apparently receiving an organ is OK under religious law.)”

barnyjr writes “According to a story from Reuters, ‘Vaccines that contain a mercury-based preservative called thimerosal cannot cause autism on their own, a special US court ruled on Friday, dealing one more blow to parents seeking to blame vaccines for their children’s illness. The special US Court of Federal Claims ruled that vaccines could not have caused the autism of an Oregon boy, William Mead, ending his family’s quest for reimbursement. … While the state court determined the autism was vaccine-related, [Special Master George] Hastings said overwhelming medical evidence showed otherwise. The theory presented by the Meads and experts who testified on their behalf “was biologically implausible and scientifically unsupported,” Hasting wrote.’”

CWmike writes “Two insurance organizations in upstate New York said on Wednesday that they will offer their members and employers virtual physician visits beginning this summer, making New York the fourth state to provide these types of services. BlueCross BlueShield of Western New York, BlueShield of Northeastern New York and technology services provider American Well said the Online Care service will allow members to talk with physicians in real time through a private online chat network or through a voice-over-IP phone call. The service also offers video chat and instant messages. Members can sign on to the insurer’s Web sites and look for physicians who are available online in various specialty areas.”

Xemu writes “Computer’s don’t make children fat, but watching TV for the same length of time does. This is shown by a recent Swedish study of all school children in Lund’s county conducted by RN Pernilla Garmy. The results were clear: The child’s obesity was directly affected by placing a TV in the child’s room, but placing a computer in the room had no effect at all. One theory is that it’s common to have a snack in front of the TV, while a computer requires a more active user, for example when chatting or playing games.”

suraj.sun writes “The virus that causes AIDS can hide in the bone marrow, avoiding drugs and later awakening to cause illness, according to new research that could point the way toward better treatments for the disease. Dr. Kathleen Collins of the University of Michigan and her colleagues report in this week’s edition of the journal Nature Medicine that the HIV virus can infect long-lived bone marrow cells that eventually convert into blood cells. The virus is dormant in the bone marrow cells, she said, but when those progenitor cells develop into blood cells, it can be reactivated and cause renewed infection. The virus kills the new blood cells and then moves on to infect other cells, said. In recent years, drugs have reduced AIDS deaths sharply, but patients need to keep taking the medicines for life or the infection comes back, Dr. Collins said.”

Costing just a cent to produce and requiring just a single drop of blood, this paper chip, designed by Harvard chemist George Whitesides, can diagnose HIV, tuberculosis, malaria and more. What substance makes this tiny marvel possible? Comic-book ink.

The water-resistant ink pushes the blood into the different paper channels, each of which contain chemicals that react with the blood and change color to indicate the presence and severity of the various diseases.

In developing countries where technology for diagnosing diseases needs to be cheap and easy for individuals to use themselves, it’s hard to imagine a test simpler than Whitesides’ “zero cost diagnostics”. The chemist presented his idea at a recent TED conference and summarized it in a video for CNN:

In his presentations, Whitesides explains how the paper tests could be produced cheaply in great numbers by inexpensive wax printers and proposes that individuals could send their results to doctors with cheap camera phones. Solutions for third world problems are often weighed down by their ambition and complexity, but the advantages of Whitesides’ work rests in its simplicity. [CNN via PopSci via Inhabitat

A few months ago you may remember my Real Review of Lexi-Comp beta for webOS. I concluded then that the app (which was a major leap forward in medical software on webOS) was exceptionally good, functioning largely as Med School in an app. Fast forward a few months, and following a prolonged hiatus from the app catalog, Lexi-Comp returned to provide healthcare practitioners with a much needed reference app.

But oh how quickly the landscape changes. Shortly after the return of Lexi-Comp, a webOS version of Epocrates, perhaps the most ubiquitous medical reference app made has also become available with a slightly different approach to medical reference on the go. In this review I’ll describe my real-world experience with Epocrates over the last several days, comparing the salient points with my experience of the current trial version of Lexi-Comp.

reporter writes “New strains of ‘Gram-negative’ bacteria have become resistant to all safe antibiotics. Though methicillin-resistant Staphylococcus aureus (MRSA) is the best-known antibiotic-resistant germ, the new class of resistant bacteria could be more dangerous still. ‘The bacteria, classified as Gram-negative because of their reaction to the so-called Gram stain test, can cause severe pneumonia and infections of the urinary tract, bloodstream, and other parts of the body. Their cell structure makes them more difficult to attack with antibiotics than Gram-positive organisms like MRSA.’ The only antibiotics — colistin and polymyxin B — that still have efficacy against Gram-negative bacteria produce dangerous side effects: kidney damage and nerve damage. Patients who are infected with Gram-negative bacteria must make the unsavory choice between life with kidney damage or death with intact kidneys. Recently, some new strains of Gram-negative bacteria have shown resistance against even colistin and polymyxin B. Infection with these new strains typically means death for the patient.”

An anonymous reader writes “Homeopathic remedies work no better than placebos, and so should no longer be paid for by the UK National Health Service, a committee of British members of parliament has concluded. In preparing its report, the committee, which scrutinizes the evidence behind government policies, took evidence from scientists and homeopaths, and reviewed numerous reports and scientific investigations into homeopathy. It found no evidence that such treatments work beyond providing a placebo effect.”

An anonymous reader writes “I’ve been working at a large company since I got out of college, so I didn’t have to give much thought to getting my own healthcare plan. Now I’m thinking about leaving the corporate world and starting out on my own. I have a family now, so I need to make sure we’re going to be covered should anything happen. Researching online turns up horror stories of people trying to get individual healthcare plans, or getting denied coverage on plans they thought they had. Does anyone else have experience going through this and what you’ve had to deal with, or am I making too big a deal of it?”
