- Predicting the Risk for Five Deadly Diseases (ptcommunity.com)
Scientists have created a powerful new tool to calculate a person’s inherited risks for heart disease, breast cancer, type 2 diabetes, chronic inflammatory bowel disease, and atrial fibrillation...By surveying changes in DNA at 6.6 million places in the human genome, investigators at the Broad Institute and Harvard University were able to identify many more people at risk than do the usual genetic tests, which take into account very few genes...The researchers are now building a website that will allow anyone to upload genetic data from a company like 23andMe or Ancestry.com. Users will receive risk scores for the five aforementioned diseases. A risk score, including obtaining the genetic data, should cost less than $100...The study began because there was general agreement among researchers that many common diseases are linked not to one mutation, but rather to thousands or millions of mutations...scientists have cataloged more than 6 million tiny changes in DNA that slightly affect the chances that people will get various diseases. Each of those genetic alterations has such a small effect—approximately a 1 percent increase or decrease in a person’s odds of getting a disease — that it would not be helpful to test for each one in isolation...But...to combine data on all of the small DNA changes to construct an individual risk score. To do that, the researchers needed a new algorithm that would weigh the significance of the variations in the genes.
- Discrepancy between trial goals, results may mask treatment risks (reuters.com)Association of Trial Registration With Reporting of Primary Outcomes in Protocols and Publications (jamanetwork.com)
Scientists often fail to publicly register plans for clinical trials or to publish the results, and the outcomes they do share may mask instances when new treatments are unsafe or ineffective, a small study suggests...One goal of asking scientists to register clinical trial plans in public research databases is to highlight the main objective of experiments and make it easy to see whether a tested treatment achieved this goal when results are published, the study authors note in JAMA...But more than one-third of the 113 clinical trials researchers examined for the study were never registered. Only 64 of the trials, or 57 percent, were published...One in five trials didn’t define a primary outcome, or clear protocols for determining if the tested treatment had achieved its main goal...Doctors rely on published evidence to guide patient care decisions, while researchers use the published literature to guide which promising areas of inquiry to pursue...Unpublished trials tend to be the ones that found treatments didn’t work or weren’t safe...Published results, meanwhile, tend to highlight successful experiments...

- Wireless system can power devices inside the body (news.mit.edu)
MIT researchers, working with scientists from Brigham and Women’s Hospital, have developed a new way to power and communicate with devices implanted deep within the human body. Such devices could be used to deliver drugs, monitor conditions inside the body, or treat disease by stimulating the brain with electricity or light...The implants are powered by radio frequency waves, which can safely pass through human tissues...in animals, the researchers showed that the waves can power devices located 10 centimeters deep in tissue, from a distance of 1 meter...Even though these tiny implantable devices have no batteries, we can now communicate with them from a distance outside the body. This opens up entirely new types of medical applications...An overarching aspiration is that regulators will provide input to the design and may incorporate framework elements and learnings into regulatory programs. .
- Big-Data Analysis Points Toward New Drug Discovery Method (technologynetworks.com)Reversal of cancer gene expression correlates with drug efficacy and reveals therapeutic targets (nature.com)
A research team led by scientists at UC San Francisco has developed a computational method to systematically probe massive amounts of open-access data to discover new ways to use drugs, including some that have already been approved for other uses...The method enables scientists to bypass the usual experiments in biological specimens and to instead do computational analyses, using open-access data to match FDA-approved drugs and other existing compounds to the molecular fingerprints of diseases like cancer. The specificity of the links between these drugs and the diseases they are predicted to be able to treat holds the potential to target drugs in ways that minimize side effects, overcome resistance and reveal more clearly how both the drugs and the diseases are working...Our hope is that ultimately our computational approach can be broadly applied, not only to cancer, but also to other diseases where molecular data exist, and that it will speed up drug discovery in diseases with high unmet needs...I’m (Bin Chen, PhD) most excited about the possibilities for applying this approach to individual patients to prescribe the best drug for each...

- Online forums give investors an early warning of shady scientific findings (statnews.com)
Scientists around the globe nowadays regularly take to the internet to scrutinize research after it’s been published — including to run their own analyses of the data and spot mistakes or fraud...And as interest in this so-called post-publication peer review has swelled, one lawyer argues, biotech and pharma companies would do well to take note. If companies and their investors aren’t reading these sites, they may be the last to know when industry-funded research is called into question...The most prominent forum for these discussions is PubPeer, where anyone can create an anonymous account and comment on published research papers. Many of the posts on PubPeer point out instances of plagiarism and duplicated or manipulated images — all of which represent retractable offenses and serious scientific misconduct. But posters often note erroneous data, flawed methodology, or even just sloppy thinking that somehow escaped the scrutiny of peer reviewers before the article was published.
- Study Indicates 75% of Human Genome is Non-functional (technologynetworks.com)
An evolutionary biologist at the University of Houston has published new calculations that indicate no more than 25 percent of the human genome is functional. That is in stark contrast to suggestions by scientists with the ENCODE project that as much as 80 percent of the genome is functional...In work published online in Genome Biology and Evolution, Dan Graur reports the functional portion of the human genome probably falls between 10 percent and 15 percent, with an upper limit of 25 percent. The rest is so-called junk DNA, or useless but harmless DNA…this new study...will help to refocus the science of human genomics...“We need to know the functional fraction of the human genome in order to focus biomedical research on the parts that can be used to prevent and cure disease,” he said. “There is no need to sequence everything under the sun. We need only to sequence the sections we know are functional.”
