Resistance To Antibiotics Found In Isolated Amazonian Tribe 51

from the strong-willed-organisms dept.
sciencehabit writes When scientists first made contact with an isolated village of Yanomami hunter-gatherers in the remote mountains of the Amazon jungle of Venezuela in 2009, they marveled at the chance to study the health of people who had never been exposed to Western medicine or diets. But much to their surprise, these Yanomami's gut bacteria have already evolved a diverse array of antibiotic-resistance genes, according to a new study, even though these mountain people had never ingested antibiotics or animals raised with drugs. The find suggests that microbes have long evolved the capability to fight toxins, including antibiotics, and that preventing drug resistance may be harder than scientists thought.

Columbia University Doctors Ask For Dr. Mehmet Oz's Dismissal 300

circletimessquare writes Dr. Mehmet Oz serves as vice chairman of Columbia University Medical Center's department of surgery. He is a respected cardiothoracic surgeon but his television show has been accused of pushing snake oil. Now other doctors at Columbia University want Dr. Oz kicked off the medical school faculty. Dr. Oz has responded on his Facebook account: "I bring the public information that will help them on their path to be their best selves. We provide multiple points of view, including mine which is offered without conflict of interest. That doesn't sit well with certain agendas which distort the facts. For example, I do not claim that GMO foods are dangerous, but believe that they should be labeled like they are in most countries around the world." In their letter, the doctors accuse Dr. Oz of quackery: "Dr. Oz has repeatedly shown disdain for science and for evidence-based medicine, as well as baseless and relentless opposition to the genetic engineering of food crops. Worst of all, he has manifested an egregious lack of integrity by promoting quack treatments and cures in the interest of personal financial gain."

When You're the NFL Commish, Getting E-Medical Record Interoperability's a Cinch 46

Posted by Soulskill
from the it's-good-to-be-the-commish dept.
Lucas123 writes: The NFL recently completed the rollout of an electronic medical record (EMR) system and picture archiving & communication system (PACS) that allows mobile access for teams to player's health information at the swipe of a finger — radiological images, GPS tracking information, and detailed health evaluation data back to grade school. But as NFL football players are on the road a lot, often they're not being treated at hospitals or by specialists whose own EMRs are integrated with the NFL's; it's a microcosm of the industry-wide healthcare interoperability issue facing the U.S. today. The NFL, however, found achieving EMR interoperability isn't so much a technological issue as a political one, and if you have publicity on your side, it's not that difficult. NFL CIO Michelle McKenna-Doyle, who led the NFL's EMR rollout, said a call from a team owner to a hospital administrator typically does the trick. Even NFL Commissioner Roger Goodell once made the call to a hospital CEO, "and things started moving in the next couple of days," McKenna-Doyle said. "They're very aware of the publicity."

New Chemical Tools Lead To Targeted Cancer Drugs 21

Posted by Soulskill
from the sniper-scope-built-out-of-proteins dept.
New submitter caudex writes: Proteins are encoded in DNA, and while the degeneracy of the genetic code works to minimize errors, a single DNA basepair mutation can change the structure of the encoded protein. When a mutated protein causes uncontrolled cell growth, we call it cancer. Unfortunately, proteins typically contain hundreds of amino acids, and developing a drug that will target the version of a protein containing one amino acid mutation is difficult. For this reason, most anticancer agents indiscriminately attack both mutant and healthy proteins and tissues. Researchers at Caltech have come up with a potentially general method for selectively drugging only the mutant protein at fault for cancerous activity, even in the crowded and complex milieu of living cells. Their proof of concept study published in Nature Chemistry targets the E17K mutation, which can be the causative mutation of many types of cancer.

How Brain Pacemakers Treat Parkinson's Disease 23

from the keeping-it-under-control dept.
the_newsbeagle writes Pharmaceutical research for neuropsychiatric disorders hasn't produced many breakthroughs lately, which may explain why there's so much excitement around "electroceutical" research. That buzzy new field encompasses deep brain stimulation (DBS), in which an implanted stimulator sends little jolts through the neural tissue. DBS has become an accepted therapy for Parkinson's and other motor disorders, even though researchers haven't really understood how it works. Now, new research may have found the mechanism of action in Parkinson's patients: The stimulation reduces an exaggerated synchronization of neuron activity in the motor cortex.

Kludgey Electronic Health Records Are Becoming Fodder For Malpractice Suits 183

Posted by timothy
from the so-it-says-here-you-were-born-in-1709 dept.
Lucas123 writes The inherent issues that come with highly complex and kludgey electronic medical records — and for the healthcare professionals required to use them — hasn't been lost on lawyers, who see the potential for millions of dollars in judgments for plaintiffs suing for medical negligence or malpractice. Work flows that require a dozen or more mouse clicks to input even basic patient information has prompted healthcare workers to seek short cuts, such as cutting and pasting from previous visits, a practice that can also include the duplication of old vital sign data, or other critical information, such as a patient's age. While the malpractice suits have to date focused on care providers, they'll soon target EMR vendors, according to Keith Klein, a medical doctor and professor of medicine at UCLA. Klein has been called as an expert witness for more than 350 state or federal medical malpractice cases and he's seen a marked rise in plaintiff attorney's using EMRs as evidence that healthcare workers fell short of their responsibility for proper care. In one such case, a judge awarded more than $7.5 million when a patient suffered permanent kidney damage, and even though physicians hadn't neglected the patient, the complexity of the EMR was responsible for them missing uric kidney stone. The EMR was ore than 3,000 pages in length and included massive amounts of duplicated information, something that's not uncommon.

Being Overweight Reduces Dementia Risk 96

Posted by timothy
from the correlation-is-easy dept.
jones_supa writes Being overweight cuts the risk of dementia, according to the largest and most precise investigation into the relationship (abstract). The researchers were surprised by the findings, which run contrary to current health advice. The team at Oxon Epidemiology and the London School of Hygiene and Tropical Medicine analyzed medical records from 2 million people aged 55 on average, for up to two decades. Their most conservative analysis showed underweight people had a 39% greater risk of dementia compared with being a normal healthy weight. But those who were overweight had an 18% reduction in dementia, and the figure was 24% reduction for the obese. Any explanation for the protective effect is distinctly lacking. There are some ideas that vitamin D and E deficiencies contribute to dementia and they may be less common in those eating more. Be it any way, let's still not forget that heart disease, stroke, diabetes, some cancers and other diseases are all linked to a bigger waistline. Maybe being slightly overweight is the optimum to strike, if the recent study is to be followed.

The Democratization of Medical Diagnosis and Discovery 96

Posted by Soulskill
from the next-level-hypochondria dept.
An anonymous reader writes: As wearable fitness devices become popular, we're seeing the beginning of a change in how untrained people can monitor their own health. On top of that, we also have access now to powerful data-sharing tools — if a patient has the means and the interest to look at the data from a doctor's medical scans, she can. A post at the NY Times argues this is leading to the democratization of medical discovery. Physicians and researchers are now saying, "Better-informed patients ... are more likely to take better care of themselves, comply with prescription drug regimens and even detect early-warning signals of illness." These tools also allow easier aggregation of data from large groups of patients (hopefully anonymized), which can provide more accurate assessments of the typical course of disease than current methods, which often rely on interpretations of interpretations.

DHS: Drug Infusion Pumps Vulnerable To Trivial Hacks 37

Posted by samzenpus
from the maintaining-the-proper-dosage dept.
chicksdaddy writes with news of a DHS warning about the vulnerability of a popular brand of drug pumps. "The Department of Homeland Security warned that drug infusion pump management software sold by Hospira contains serious and exploitable vulnerabilities that could be used to remotely take control of the devices.

The MedNet server software manages drug libraries, firmware updates, and configurations of Hospira intravenous pumps. DHS's Industrial Control System Computer Emergency Response Team (ICS-CERT) said in an advisory issued Tuesday that the MedNet software from the firm Hospira contains four critical vulnerabilities – three of them capable of being exploited remotely. The vulnerabilities could allow a malicious actor to run malicious code on and take control of the MedNet servers, which could be used to distribute unauthorized modifications to medication libraries and pump configurations.

The vulnerabilities were discovered by independent security researcher Billy Rios and reported to both Hospira and ICS-CERT. The vulnerabilities vary in their severity. Among the most serious is Rios's discovery of a plaintext, hard-coded password for the SQL database used by the MedNet software (CVE-2014-5405e). By obtaining that password, an attacker could compromise the MedNet SQL server and gain administrative access to the workstation used to manage deployed pumps."

Invaders Demand Flu Shots 57

An Anonymous Coward writes in with this bit from the Intercontinental Radio News Network describing an ongoing situation near Grovers Mill, New Jersey. What was originally thought to be a large meteor crash near the Wilmuth farm has turned out to be the beginning of a Martian invasion. Local officials have had limited contact with the invaders at this point, but their actions so far have the experts scratching their heads. "I expected to be disintegrated or turned into a pile of goo by their advance weaponry but all they did was ask where they could get cold medicine," says a first responder. Initial reports indicate that the aliens have gathered all the vitamin C and antihistamine tablets from the downtown area and have now surrounded the local hospital in their strange ships and are demanding flu shots. A Centers for Disease Control and Prevention spokesman says that the agency theorizes the red Martian dust makes the cold and flu season almost unbearable and hopes that the aliens will leave soon after their treatments. He adds: "While alien invaders are terrifying we can take heart in the fact that our flu shot campaign has performed beyond all expectations this year by reaching Mars. We consider their demands our success."

Material Made From Crustaceans Could Combat Battlefield Blood Loss 76

Posted by Soulskill
from the also-good-news-for-swashbucklers dept.
MTorrice writes: A foam composed of a polymer derived from crustacean shells may prevent more soldiers from falling victim to the most prolific killer on the battlefield: blood loss. Pressure is one of the best tools that medics have to fight bleeding, but they can't use it on severe wounds near organs. Here, compression could do more harm than good. First responders have no way to effectively dam blood flows from these non-compressible injuries, which account for the majority of hemorrhagic deaths. The new foam could help stop bleeding in these types of injuries. It relies on chitosan, a biopolymer that comes from processed crustacean shells. By modifying the chitosan, the developers gave the material the ability to anchor blood cells into gel-like networks, essentially forming blood clots. The researchers dispersed the modified chitosan in water to create a fluid they could spray directly onto noncompressible wounds.

Is the Apple Watch a Useful Medical Device? (Video) 47

Let's kill the suspense right away by answering the title question, 'Probably not.' For one thing, according to interviewee Alfred Poor, the Apple Watch is in no way linked to the Apple Research Kit. Dr. Poor is editor of the Health Tech Insider website, so he follows this kind of thing more carefully than most people. And the Apple watch is not the only device mentioned in this video (or transcript, if you prefer reading to listening). If you want to ruminate about the possibility of direct mind control, for instance, you need to know about the Thync, whose vendor calls it 'A groundbreaking wearable device that enables you to shift your state of mind in minutes.' They say it 'induces on-demand shifts in energy, calm, or focus.' It even has a 'pleasure' setting. Crank that to 11 and you might happily spend your days prone, being fed by a drip and emptied by a catheter, moving only when an attendant turns you over to keep bedsores from developing -- not that you'll care if they do -- as you spend the rest of your life in an artificially-induced joyful stupor.

Child Psychotherapist: Easy and Constant Access To the Internet Is Harming Kids 353

First time accepted submitter sharkbiter sends note that one of the UK's foremost psychotherapists has concerns that smartphones may be harmful to the mental health of children. "Julie Lynn Evans has been a child psychotherapist for 25 years, working in hospitals, schools and with families, and she says she has never been so busy. 'In the 1990s, I would have had one or two attempted suicides a year – mainly teenaged girls taking overdoses, the things that don't get reported. Now, I could have as many as four a month.'.... Issues such as cyber-bullying are, of course, nothing new, and schools now all strive to develop robust policies to tackle them, but Lynn Evans’ target is both more precise and more general. She is pointing a finger of accusation at the smartphones - “pocket rockets” as she calls them – which are now routinely in the hands of over 80 per cent of secondary school age children. Their arrival has been, she notes, a key change since 2010. 'It’s a simplistic view, but I think it is the ubiquity of broadband and smartphones that has changed the pace and the power and the drama of mental illness in young people.'”

An anonymous reader sends word that a common weed killer may cause cancer according to the World Health Organization. "The world's most widely used weed killer can 'probably' cause cancer, the World Health Organization said on Friday. The WHO's cancer arm, the International Agency for Research on Cancer, said glyphosate, the active ingredient in Roundup and other herbicides, was 'classified as probably carcinogenic to humans.' It also said there was 'limited evidence' that glyphosate was carcinogenic in humans for non-Hodgkin lymphoma." Unsurprisingly, Monsanto, Roundup's manufacturer disagrees saying there is no evidence to support the findings and calls on WHO to hold a meeting to explain their conclusions.

New Alzheimer's Treatment Fully Restores Memory Function For Mice 109

Posted by timothy
from the better-than-deja-vu dept.
New submitter wrp103 writes Australian researchers have come up with a non-invasive ultrasound technology [abstract] that clears the brain of neurotoxic amyloid plaques — structures that are responsible for memory loss and a decline in cognitive function in Alzheimer's patients. A slice: Publishing in Science Translational Medicine, the team describes the technique as using a particular type of ultrasound called a focused therapeutic ultrasound, which non-invasively beams sound waves into the brain tissue. By oscillating super-fast, these sound waves are able to gently open up the blood-brain barrier, which is a layer that protects the brain against bacteria, and stimulate the brain’s microglial cells to move in. Microglila cells are basically waste-removal cells, so once they get past the blood-brain barrier, they’re able to clear out the toxic beta-amyloid clumps before the blood-brain barrier is restored within a few hours. The team reports fully restoring the memories of 75 percent of the mice they tested it on, with zero damage to the surrounding brain tissue. They found that the treated mice displayed improved performance in three memory tasks - a maze, a test to get them to recognise new objects, and one to get them to remember the places they should avoid.

Excess Time Indoors May Explain Rising Myopia Rates 144

Posted by timothy
from the buildings-hate-us dept.
Nature reports that an unexpected factor may be behind a growing epidemic of nearsightedness: time spent indoors. From the article: Because the eye grows throughout childhood, myopia generally develops in school-age children and adolescents. About one-fifth of university-aged people in East Asia now have this extreme form of myopia, and half of them are expected to develop irreversible vision loss. This threat has prompted a rise in research to try to understand the causes of the disorder — and scientists are beginning to find answers. They are challenging old ideas that myopia is the domain of the bookish child and are instead coalescing around a new notion: that spending too long indoors is placing children at risk. “We're really trying to give this message now that children need to spend more time outside,” says Kathryn Rose, head of orthoptics at the University of Technology, Sydney.

Internet of Things Endangered By Inaccurate Network Time, Says NIST 166

Posted by Soulskill
from the turn-left-in-+/-3-minutes dept.
An anonymous reader writes: Current standards of network timekeeping are inadequate to some of the critical systems that are being envisaged for the Internet of Things, according to a report (PDF) by the National Institute of Standards and Technology (NIST). The report says, "A new economy built on the massive growth of endpoints on the internet will require precise and verifiable timing in ways that current systems do not support. Applications, computers, and communications systems have been developed with modules and layers that optimize data processing but degrade accurate timing." NIST's Chad Boutin likens current network accuracy to an attempt to synchronize watches via the postal system, and suggests that remote medicine and self-driving cars will need far higher standards in order not to put lives at risk. He says, "modern computer programs only have probabilities on execution times, rather than the strong certainties that safety-critical systems require."
