Academic press offices are known to overhype their own research. But the University of Maryland recently took this to appalling new heights — trumpeting an incredibly shoddy study on chocolate milk and concussions that happened to benefit a corporate partner. It's a cautionary tale of just how badly science can go awry as universities increasingly partner with corporations to conduct research. [more inside]
A writer for Gray's Anatomy on confronting the doctor who missed her rare cancer. I didn't question him when he prescribed anti-depressants—rather than another MRI—after I confided I was sleep deprived from constant knifing back pain. I convinced myself that his inability to fix me was my failure, not his. I wasn't tough enough. I weighed too much, exercised too little. It was my fault I couldn't walk to the grocery store without a cane and a fistful of Vicodin. He called me "impatient" and "emotional." It never occurred to me that being "female" was perhaps the most dangerous label of all. [more inside]

Humans 2.0 - "With CRISPR, scientists can change, delete, and replace genes in any animal, including us. Working mostly with mice, researchers have already deployed the tool to correct the genetic errors responsible for sickle-cell anemia, muscular dystrophy, and the fundamental defect associated with cystic fibrosis. One group has replaced a mutation that causes cataracts; another has destroyed receptors that H.I.V. uses to infiltrate our immune system." [more inside]

Can’t Swallow a Pill? There’s Help for That [New York Times]
Most children start swallowing pills around age 10, said Dr. Tanya Altmann, a pediatrician in Calabasas, Calif., and a spokeswoman for the American Academy of Pediatrics. And 20 percent to 40 percent are unable to swallow a standard-size pill or capsule, according to a recent study in the journal Pediatrics. [...] Many never outgrow the problem.[more inside]
New Ebola vaccine shows 100% success rate in clinical trial. Today the World Health Organization has announced that the rVSV-ZEBOV vaccine had a 100% success rate in preventing onset of the disease if administered within 10 days of exposure (n=4,000). In response to the current outbreak in West Africa that has afflicted over 27,000 and killed over 11,000, this collaborative effort led by the WHO pushed the vaccine through a process that usually takes more than a decade in just 12 months. Official paper from The Lancet here (pdf).
New research into the pain processing of mice has found male and female mice process pain differently, and the discovery may also apply to other species, including humans.

The 2015 Dietary Guidelines Advisory Committee (DGAC) report, submitted to the U.S. Department of Health and Human Services and the U.S. Department of Agriculture, makes a historic change: for the first time since 1980, the report no longer recommends the restriction of dietary cholesterol nor of total dietary fat. An article published today in JAMA calls on HHS and USDA to heed the DGAC report. The article goes on to praise the report's new emphasis: reducing consumption of sugar and refined carbohydrates, and increasing consumption of whole foods (even those high in fats).
New U.S. government research indicates that female military veterans commit suicide at nearly six times the rate of other women and at rates nearly equal to that of male veterans -- a finding that surprised researchers because women are generally are far less likely than men to commit suicide. The findings raise questions about the backgrounds and experiences of women who serve in the United States' armed forces. [more inside]
Loaded with Lead. America has an estimated 10,000 gun ranges and 40 million annual recreational shooters. But when guns are fired with lead-based ammunition, they spread a toxin: lead vapor and dust. A year-long Seattle Times investigation shows that due to poor ventilation and contact with lead-coated surfaces, thousands of workers, shooters and their family members have been contaminated and been made sick at shooting ranges nationwide. Reckless range owners/operators, unenforced regulations as well as a lack of oversight and inspections are to blame. [more inside]
For the past few years, a small group of psychiatrists, researchers, educators, and game designers have run a quiet but intense footrace to become the first to earn FDA approval for a medically sound, prescription-strength video game for ADHD. That’s not a metaphor. They are seeking approval for a game that a doctor can actually prescribe..In this excerpt from his new book, posted on Medium, journalist Greg Toppo discusses a variety of new neurogames and how they may in the future treat conditions like ADHD and anxiety, strengthen skills like multitasking and mindfulness, and reduce the need for pharmaceutical interventions for children. (Fair warning, the article has an animated header image that may annoy, so you may want to scroll right on down past it before you start reading.)
The CRISPR Revolution [ungated: 1,2,3] - "Biologists continue to hone their tools for deleting, replacing or otherwise editing DNA and a strategy called CRISPR has quickly become one of the most popular ways to do genome engineering. Utilizing a modified bacterial protein and a RNA that guides it to a specific DNA sequence, the CRISPR system provides unprecedented control over genes in many species, including perhaps humans. This control has allowed many new types of experiments, but also raised questions about what CRISPR can enable." [more inside]
Fish oil: it's been touted as a solution to heart health, dementia, glaucoma, and a host of other ailments. Unfortunately, it turns out that most of the evidence for its benefits is equivocal at best. And it turns out that fish oil isn't particularly useful for our pets, either. Worse, it turns out that the foundational study that kicked off interest in fish oil as a supplement is not quite as promising for fish oils as it is usually construed and cited. Given that fish oil can induce strokes in high quantities (and may interfere with treatments like chemotherapy), is poorly regulated, and is expensive, should we be promoting fish oil supplements as strongly as we do?
Health-conscious people are haunted by the idea that they “should” correct their posture, and many fight a chronic, uncertain and tedious battle against crookedness. But is it necessary? After working as a massage therapist for many years, I became confident that poor posture is a “real” thing. I think it is sometimes a factor in chronic pain, mostly later in life, and probably can also be improved in some cases with a little effort. But it’s not a straightforward business, this posture stuff! There aren’t many “easy wins” for people here. And there’s plenty of potential to waste time and money — or even get hurt. Delving deeper into the topic as a journalist, studying the scientific literature and learning more from countless readers and experts, I have developed many reasonable doubts about posture’s importance.
Your new kidney is in the cloud. When former software developer David Jacobs was fortunate enough to get a kidney transplant eleven years ago, it occurred to him that there had to be a better way to match recipients with potential donors... so he bankrolled a company, and designed the cloud-based software needed to do it. As a result, thanks to paired kidney exchanges, a single kidney donation in San Francisco is saving six lives over the next few days... and will soon be saving a total of twelve lives, while removing people from the kidney waiting list, reducing the organ wait time for patients who don't have the time to spare.
The annual James Dyson Award is open to current and recent design engineering students. The winner this year is James Roberts with his inflatable incubator MOM.

It's easy to break a patient like Rogelio—Mexican and poor and chronically ill—down to his potassium level and to make medical decisions according to a number. But that's only part of the story of how the undocumented ill are cared for here in Houston. Within this city's history—a history that includes segregation during the 1960s, a large immigrant population, strong economic growth over the past half century, not to mention the world's largest medical center—is the story of how Houston sought local solutions to provide compassionate care to its indigent and undocumented, the latter of which, some might say, have helped the city grow.Dr. Ricardo Nuila reports from the emergency room at Houston's Ben Taub Hospital, where Harris County's undocumented ill can avail themselves of some of the country's best health care: Taking Care of Our Own.

According to the American Society of Addiction Medicine, addiction is “a primary, chronic disease of brain reward, motivation, memory and related circuitry.” However, that’s not what the epidemiology of the disorder suggests. By age 35, half of all people who qualified for active alcoholism or addiction diagnoses during their teens and 20s no longer do, according to a study of over 42,000 Americans in a sample designed to represent the adult population.

“The gap between what patients and doctors expect from these procedures, and the benefit that they actually provide, shows the profound impact of a certain kind of mechanical logic in medicine,” he explains. “Even though doctors value randomized clinical trials and evidence-based medicine, they are powerfully influenced by ideas about how diseases and treatments work. If doctors think a treatment should work, they come to believe that it does work, even when the clinical evidence isn’t there.” [more inside]
