Blood Test May Predict If You Really Need Antibiotics
Antibiotics are often over-prescribed and misused, leading to a global threat of antibiotic resistance. But in a new study, researchers say they’re a step closer to developing a rapid blood test that distinguishes between viral and bacterial respiratory infections, which would mean more accurate antibiotic prescriptions.
Duke University researchers described in Science Translational Medicine a simple blood test that within an hour could alert a doctor whether antibiotics are truly necessary. The test, while still in the early development stages, measures an infected person’s genetic reaction to a microbe.
“Considering the huge vacuum and the void in helping doctors make decisions about antibiotic use, just about any kind of test is an improvement over what’s currently available,” said Dr. Ephraim Tsalik, assistant professor of medicine at Duke University.
Currently, around 50 percent of antibiotic prescriptions for respiratory infections may be unnecessary, according to the American College of Physicians and the Centers for Disease Control and Prevention.

No Pill for this Ill
Does the medical profession really want society to be healthy?
Does this world, where business and money interests are supreme, want
society to be healthy and tranquil? The answer is a big NO. No one wants
to break her/his own rice bowl. The pharmaceutical industry, the most
powerful lobby in the world today—thrice as big and powerful as the oil
industry—will certainly not want people to be healthy. The medical
profession is trying its best to make more and more people come into
their net by ‘regular health check-ups’ of the healthy, run for the
heart, run for cancer and so on; it is also doing its best to create
iatrogenic illnesses. Hospitals, especially the corporate ones, seek
more surgical post-operative complications, as the latter nets more
money into their kitty than the original surgery itself.
Last year’s budget to treat non-fatal adverse drug reactions (ADRs) in
Europe alone was $80 billion! Please give me one good reason why anyone
should want to treat simple acne with azithromycin; but that is exactly
what is done and on a long-term basis. A recent issue of The Times of
India, in a front page news report, mentioned a study done in one Delhi
medical college hospital, which showed that all (did I say all?) germs
in the acne now have become resistant to azithromycin, a high-end
antibiotic reserved for respiratory infections like pneumonia!
Antibiotics are the time bombs waiting to explode anytime now.

How to Save People From Snakebites
The desperate search for better antidotes that can work against many types of venom.
Matt Lewin waited for the paralysis to set in. Two anesthesiologists and an emergency-room doctor monitored his vitals while the mivacurium moved through him. Mivacurium paralyzes skeletal muscles the same way a cobra bite does, with the venom’s most deadly effect: It causes the diaphragm to stop contracting, and the victim suffocates. The doctors had chemically immobilized
Lewin, like a snake would, to see if they could reanimate him with a new snake-venom antidote.
It was an antidote Lewin himself had developed: a nasal spray of the compound neostigmine. Doctors first described neostigmine’s ability to undo snake-induced paralysis in 1972, but it is usually injected, and administered by doctors in a hospital. Lewin wanted to create a first-aid–style, no-supervision-required version that a person could stick up her nose after a cobra bit her. But his Afrin-like version had never been tested against snakebites—not even in mice, rats, chimps, or the other lab-test favorites that usually precede humans.
Lewin, prone in the research room, was the first test subject. (A known antidote to mivacurium waited right next to him, just in case.) At first, the effects of mivacurium felt relaxing, the ultimate shavasana. Then, Lewin couldn’t see. His breathing got shallower. He had trouble swallowing, couldn’t lift his head. Speech departed.
He felt impatient and dependent, like a child whose well-being depends on others. “Even though I knew I was being monitored intensely, they appeared to me very casual,” he says, “because they couldn’t experience what I was experiencing.” And what he was experiencing was a slow, staggering walk toward death (metaphorically, since he couldn’t even wiggle a toe). He could only hope that his antidote would grab his hand and lead him back.
“Everything that was going on was just in my head,” he says, “which was, give me the drug. Stop talking about Hank Williams, Jr.”
Underneath his anxiety, though, he knew that the doctors were confident and focused, playing out the scenario they had dress-rehearsed and planned for months. When he heard them approach his nose with the antidote, he got so excited that his heart monitor began beeping like crazy before the mist even entered his nasal cavity.
The effects were almost instantaneous. The muscles under his face jerked awake and reordered themselves. It felt cartoony, like CGI of a human morphing into an animal. Minutes later, the rest of his body worked. He rose from the bed like Lazarus.
“It worked!” he said.
His words came out slurry and garbled. He cried.
