The FDA Just Made It a Lot Easier for DNA Health Tests to Hit the Market

Tue, 11/07/2017 - 16:59

(Gizmodo) – The newly proposed regulations will allow genetic health tests to make it to market without prior review. Companies seeking to sell such tests would have to come to the FDA for a one-time review. But after getting that initial FDA stamp of approval, any subsequent genetic health test the company develops will not face further regulatory hurdles. “Our goal is to streamline the regulatory pathway to get innovative medical products to people more efficiently, while providing the FDA assurances that consumers seek,” said Gottlieb.

Should Children Form Emotional Bonds with Robots?

Tue, 11/07/2017 - 16:56

(The Atlantic) – Stefania Druga and Randi Williams, the researchers behind the study, want to know how children perceive smart robots, and, eventually, to study how those bots affect kids’ cognitive development. So far, they’ve discovered that little children (ages 3 and 4) aren’t sure whether the robots are smarter than they are, but that slightly older children (ages 6 to 10) believe the robots to have superior intelligence. Druga and Williams were inspired by the research of the legendary Sherry Turkle, who wrote a highly influential 1984 book called The Second Self.

Brain Imaging Reveals ADHD as a Collection of Different Disorders

Tue, 11/07/2017 - 16:42

(Science Daily) – Researchers have found that patients with different types of attention-deficit/hyperactivity disorder (ADHD) have impairments in unique brain systems, indicating that there may not be a one-size-fits-all explanation for the cause of the disorder. Based on performance on behavioral tests, adolescents with ADHD fit into one of three subgroups, where each group demonstrated distinct impairments in the brain with no common abnormalities between them.

Over-the-Counter Painkillers Treated Painful Injuries Just as Well as Opioids in New Study

Tue, 11/07/2017 - 16:36

(Los Angeles Times) – In an opioid epidemic that currently claims an average of 91 lives per day, there have been many paths to addiction. For some, it started with a fall or a sports injury, a trip to a nearby emergency room and a prescription for a narcotic pain reliever that seemed to work well in the ER. New research underscores how tragically risky — and unnecessary — such prescribing choices have been. In a new study of patients who showed up to an emergency department with acute pain in their shoulders, arms, hips or legs, researchers found that a cocktail of two non-addictive, over-the-counter drugs relieved pain just as well as — and maybe just a little better than — a trio of opioid pain medications widely prescribed under such circumstances.

For Patients with Heart Failure, Little Guidance as Death Nears

Tue, 11/07/2017 - 16:26

(New York Times) – Yet there are no widely accepted guidelines for dealing with these patients as they near death. Cancer specialists regularly move their patients to hospice at the end of life, for instance, but few cardiologists even think of it. Heart patients account for just 15 percent of hospice deaths, while cancer patients make up half, according to a recent study. That paper, published in the Journal of the American College of Cardiology, reviewed a number of ways in which heart patients are let down at the end of life. Implanted defibrillators often remain activated until the very end, for example, even for those in hospice.

Tokyo: Artificial Intelligence ‘Boy’ Shibuya Mirai Becomes World’s First AI Bot To Be Granted Residency

Tue, 11/07/2017 - 16:06

(Newsweek) – A chatbot programmed to be a seven-year-old boy has become the first AI bot to be granted official residence in Tokyo, Japan. Shibuya Mirai is the latest resident of Shibuya, a Tokyo ward with a population of around 224,000 people, despite only existing as a chatbot on the Line messaging app. The ward’s decision to make Mirai—meaning ‘future’ in Japanese—an official resident is part of a project aimed at making the local government more familiar and accessible to locals. The chatty seven-year-old is designed to listen to the opinions of Shibuya residents.

Politically Connected Cancer Mogul Faces Questions over His Genetic Tests

Tue, 11/07/2017 - 16:02

(Politico) – Patrick Soon-Shiong, the medical entrepreneur who has expanded his influence in Washington by cultivating close ties to both parties, has struggled to meet analysts’ expectations for sales of his GPS genetic test, the key to his plan to transform cancer treatment by matching patients with tailored drug treatments. At the same time, sales of the GPS test are being boosted by purchases from hospitals and clinics associated with doctors who have financial ties to his network of for-profit and non-profit companies.

Euthanasia and Physician-Assisted Suicide Not Meeting Due Care Criteria in the Netherlands

Mon, 11/06/2017 - 14:27

(BMJ) – Of 33 DCNM, [due care not met], cases identified (occurring 2012–2016), 32 cases (97%) were published online and included in the analysis. 22 cases (69%) violated only procedural criteria, relating to improper medication administration or inadequate physician consultation. 10 cases (31%) failed to meet substantive criteria, with the most common violation involving the no reasonable alternative (to EAS [euthanasia and physician-assisted suicide]) criterion (seven cases). Most substantive cases involved controversial elements, such as EAS for psychiatric disorders or ‘tired of life’, in incapacitated patients or by physicians from advocacy organisations. Even in substantive criteria cases, the RTE’s focus was procedural.

‘You Could Do It Tomorrow’: How Soon Is ‘Soon’ for Trans Women Wanting to Give Birth?

Mon, 11/06/2017 - 14:21

(Sacramento Bee) – Medical treatments for transgender people have gone “mainstream,” according to Richard Paulson, an obstetrician-gynecologist in Los Angeles and the president of the American Society for Reproductive Medicine. With that comes the prospect for a medical development that could shatter some of the most strongly-held beliefs for centuries about biological sex and the ability to conceive a child. In short, some scientists believe that transgender women — those who were assigned male at birth — could soon give birth.

Swedish Ethics Review Board: Macchiarini Is Guilty

Mon, 11/06/2017 - 14:11

(The Scientist) – The Expert Group on Scientific Misconduct at Sweden’s Central Ethics Review Board (CEPN) has found evidence of scientific misconduct in all six of Paolo Macchiarini’s synthetic trachea transplantation publications it reviewed. The papers reported on the implantations of three patients with artificial tracheae—all of whom died.

Bioethicist: History Tells Us CRISPR Fears Are Overblown

Mon, 11/06/2017 - 14:01

(Medscape) – History tells us that fears about designer babies are exaggerated when it comes to the alteration, deletion, or swapping of genes in human embryos, renowned bioethicist Alta Charo, PhD, said during a TEDMED 2017 talk in Palm Springs, California. “In fact, we’ve now had 50 years of responsible and useful advances in genetic screening, genetic testing and, most recently, genetic treatment,” said Dr Charo, who is professor of law and bioethics at the University of Wisconsin in Madison and a member of the National Academies’ Human Gene Editing Initiative.

The Public’s Distrust of Biotech Is Deepening. Commercialization May Be to Blame.

Mon, 11/06/2017 - 13:48

(Undark) – Harvard medical geneticist Robert C. Green, reflective, cautious, and as decent as a scientist can sound, took to television last month to make people aware of an open trial at the Brigham and Women’s Hospital, which uses genomic sequencing to screen for variants that can predict 1,800 genetic conditions in newborns. The cutting-edge study foreshadows what genetic science might bestow to human health, but the more interesting takeaway is that the failure of the study to connect with the public — very few are enrolling — may signify a deepening distrust of biotech.

Should Patients with Dementia Be Able to Decline Spoon-Feeding?

Mon, 11/06/2017 - 13:34

(NPR) – People who abhor the thought of being kept alive with feeding tubes or other types of artificial nutrition and hydration have, for years, had a way out: They could officially document their wishes to halt such interventions using advance directives. Even patients diagnosed with progressive dementia who are able to record crucial end-of-life decisions before the disease robs them of their mental capacity could write advance directives. But caregivers and courts have rarely honored patients’ wishes to refuse food and fluids offered by hand.

Easing Burnout for Health Care Providers

Mon, 11/06/2017 - 13:21

(U.S. News & World Report) – More than half of U.S. physicians have at least one symptom of professional burnout, Shanafelt said, and the problem is getting worse. “We are seeing increasing rates of distress,” he said, and that equates to decreased quality of care for the patient – burnout correlates with mortality rates. There are implications for the health care professional, too, such as increased odds of substance abuse, suicide and leaving the profession.

Scientists Faked a Procedure on Patients to Find that Stents Don’t Actually Make them Feel Better

Fri, 11/03/2017 - 11:33

(Quartz) – Researchers at Imperial College London conducted a study on 200 patients who had one severely blocked artery to the heart, which starves the heart of oxygen and causes chest pain, especially when someone with the condition tries to exert themselves. For six weeks, the research team gave the participants statins and blood pressure medication, and then each patient underwent a routine procedure to insert a stent into the affected arteries. Except only about half of the patients actually got a stent.

Why Plague Caught Madagascar Unaware

Fri, 11/03/2017 - 11:31

(BBC) – Madagascar is facing the worst outbreak of plague in 50 years. There have been more than 1,800 cases and 127 deaths since the start of August, according to new figures. The island off the south-east coast of Africa is used to seeing about 400 cases of mostly bubonic plague in the same rural areas every year.  But this year it has developed into the deadlier pneumonic version and spread to much more populated areas, including the capital.

Heart Disease Death Rate Plummets, But Overdose Death Rate Rises, CDC Says

Fri, 11/03/2017 - 11:28

(CNN) – Three new reports from the US Centers for Disease Control and Prevention bring both good and bad news about Americans’ health. Death rates for heart disease, cancer and HIV are all down in the United States in the year ending mid-2017 compared to the same period last year, according to one report published Friday by the CDC’s National Center for Health Statistics. Despite these “wins,” the overall mortality rate has increased from the same time last year, the report also indicated. This overall uptick includes the death rate for drug overdoses.

MDMA’s Journey from Molly to Medicine

Fri, 11/03/2017 - 11:26

(Scientific American) – The speed and effectiveness of the psychedelic experience Casey describes has caught the attention of the Food and Drug Administration, despite the Drug Enforcement Administration’s 1985 classification of MDMA as a Schedule I substance—the murderer’s row of illicit drugs that include heroin and are deemed to have no medical value. This past August the FDA granted MDMA “breakthrough therapy” status in the treatment of PTSD, meaning it may provide a substantial improvement over existing therapies. The agency will work closely with MAPS—a privately funded research institute founded 31 years ago in Santa Cruz, California—to design and conduct phase III trials starting next spring. This marks the first time psychedelic-assisted psychotherapy will be monitored in phase III trials for possible prescription use.

Can Math Be Used to Predict an Outbreak?

Fri, 11/03/2017 - 11:17

(Milwaukee Journal Sentinel) – While sitting in séances and pursuing Marabou storks may seem like extreme measures, the data researchers gather in the field — everything from the size and frequency of bat litters, to the levels of virus in their blood serum — is being used to build mathematical tools that scientists hope will achieve a landmark in human health. They want to predict an infectious outbreak before it happens.

West Virginia Cities Sue Accrediting Group over Painkillers

Fri, 11/03/2017 - 11:13

(STAT News) – Several West Virginia municipalities are suing The Joint Commission, claiming the Chicago-based health care accreditation group downplayed the dangers of prescription painkillers and helped fuel addictions. The Charleston Gazette-Mail reports that the cities of Charleston, Huntington and Kenova and the town of Ceredo filed the class-action lawsuit Thursday in Charleston.
