Un nuevo estudio revela una forma de ‘engañar’ a las bacterias responsables de enfermedades como la tuberculosis y la úlcera gástrica y duodenal que consiste en evitar el normal funcionamiento de una de las enzimas que necesitan para sobrevivir.

Twitter is partnering with publisher Everyday Health to deliver public-health alerts and to sell ad packages related to health topics.
The publisher, which owns a host of health-related properties like Daily Glow and Jillian Michaels, will be able to scour the 2 million health-related daily tweets in the U.S. to see if anything is overindexing in a region to suggest that there’s an impending outbreak (which could include mental-health issues). The deal is similar to host of partnerships with the likes of ESPN, A&E, Conde Nast and Major League Baseball.

Pain is a big problem. If you read about pain management centers, you might think it had been solved. It has not, yet. And when no effective treatment exists for a medical problem, it leads to a tendency to clutch at straws. Research has shown that acupuncture is little more than such a straw.
Although it is commonly claimed that acupuncture has been around for thousands of years, it has not always been popular, even in China. For almost 1000 years, it was in decline, and in 1822, Emperor Dao Guang issued an imperial edict stating that acupuncture and moxibustion should be banned forever from the Imperial Medical Academy.
Acupuncture continued as a minor fringe activity in the 1950s. After the Chinese Civil War, the Chinese Communist Party ridiculed Traditional Chinese Medicine, including acupuncture, as superstitious. Chairman Mao Zedong later revived Traditional Chinese Medicine as part of the Great Proletarian Cultural Revolution of 1966. The revival was a convenient response to the dearth of medically trained people in postwar China and a useful way to increase Chinese nationalism. It is said that Chairman Mao himself preferred Western medicine. His personal physician quotes him as saying “Even though I believe we should promote Chinese medicine, I personally do not believe in it. I do not take Chinese medicine.”
The political, or perhaps commercial, bias seems to still exist. It has been reported (by authors who are sympathetic to alternative medicine) that “all trials [of acupuncture] originating in China, Japan, Hong Kong, and Taiwan were positive.”
Acupuncture was essentially defunct in the West until President Nixon visited China in 1972. Its revival in the West was largely a result of a single anecdote promulgated by journalist James Reston in the New York Times after he had acupuncture in Beijing for postoperative pain in 1971. Despite his eminence as a political journalist, Reston had no scientific background and evidently did not appreciate the post hoc ergo propter hoc fallacy, or the idea of regression to the mean.
After Reston’s report, acupuncture quickly became popular in the West. Stories circulated that patients in China had open heart surgery using only acupuncture. The Medical Research Council (UK) sent a delegation, which included Alan Hodgkin, to China in 1972 to investigate these claims, about which they were skeptical. The claims were repeated in 2006 in a British Broadcasting Corporation TV program, but Simon Singh (author of Fermat’s Last Theorem) discovered that the patient had been given a combination of 3 very powerful sedatives (midazolam, droperidol, fentanyl) and large volumes of local anesthetic injected into the chest. The acupuncture needles were purely cosmetic.
Curiously, given that its alleged principles are as bizarre as those on any other sort of prescientific medicine, acupuncture seemed to gain somewhat more plausibility than other forms of alternative medicine. As a result, more research has been done on acupuncture than on just about any other fringe practice.
The outcome of this research, we propose, is that the benefits of acupuncture are likely nonexistent, or at best are too small and too transient to be of any clinical significance.
Most patients who enter the gym of the San Mateo Medical Center in California are there to work with physical therapists. But a few who had knee replacements are being coached by a digital avatar instead.
The avatar, Molly, interviews them in Spanish or English about the levels of pain they feel as a video guides them through exercises, while the 3-D cameras of a Kinect device measure their movements. Because it’s a pilot project, Paul Carlisle, the director of rehabilitation services, looks on. But the ultimate goal is for the routine to be done from a patient’s home.
“It would change our whole model,” says Carlisle, who is running the trial as the public hospital looks for creative ways to extend the reach of its overtaxed budget and staff. “We don’t want to replace therapists. But in some ways, it does replace the need to have them there all the time.”
Receiving remote medical care is becoming more common as technologies improve and health records get digitized. Sense.ly, the California startup running the trial, is one of more than 500 companies using health-care tools fromNuance, a company that develops speech-recognition and virtual-assistant software. “Our goal is basically to capture the patient’s state of mind and body,” says Ivana Schnur, cofounder of Sense.ly and a clinical psychologist who has spent years developing virtual-reality tools in medicine and mental health.
Using Sense.ly’s platform, patients can communicate their condition to an emotionally reactive avatar through their phone, desktop, or TV. The avatar asks the patient simple questions, and if programmed by a doctor, it can answer questions too—such as what a diabetes patient with high blood-sugar readings should eat that day. The software also collects data from other medical devices that a patient uses, such as a glucose meter, and can capture gestures with a Kinect. The reports sent to the doctor include red-flag notifications to act on right away; charts, graphs, and analytics tracing the patient’s progress over time; and a transcript of the voice interaction.
“A physician’s time is always limited,” says Benjamin Kanter, chief medical information officer at Palomar Health in San Diego. “For a long time, we’ve had the challenge of just getting information into the system. Now the system is starting to actually help me.”
Schnur says one real advance is the avatar itself, which is important in helping both patients and doctors to trust the interactions. Molly, still a work in progress, can modulate her tone of voice and facial expressions. Schnur says that sometimes patients are more willing to share sensitive information with a nonjudgmental avatar than with a doctor.
Patients in San Mateo seem to like the interaction, Carlisle says, and he does too: “I’ve gotten used to the avatar. I look forward to seeing it when it comes online.”
The Sense.ly software, currently in beta, is also being tested at an addiction and detox clinic in California, doing patient intake and assessment in a crowded waiting room. Schnur hopes the system will eventually be used for even more complex tasks. The company, a product of the French telecommunication company Orange’s Silicon Valley incubator program, is working to include additional features, such as the ability to interpret and respond to a patient’s facial expressions.
Of course, doctors see some risks in such approaches, especially if the software makes an error or misinterprets an interaction. Kanter points out that although electronic systems often reduce errors, any errors that occur can propagate more quickly than those made only on paper.
Carlisle, who will enroll 50 to 60 patients by the time the study is done, is looking forward to getting more data. Over time, he hopes, not only will he improve the care of individual patients in their home environments, but what he learns from the data will improve therapy for everyone.
