You just ate a bunch of poisonous stuff. Some of it was especially nasty, and I don't mean the cooking, rather, the chemicals in the food. Chances are that you are fine. 

So am I, with the exception of sitting (mostly still) for two hours in a car with my mother (wonderful woman and I love her to death, but good lord, can she talk!) on the Long Island Expressway (LIE)—a misnomer if ever there were one—to attend Thanksgiving dinner. 

The day was not lacking in stress. This is me channeling Lloyd Bridges: 

New research finds that progesterone supplements in the first trimester of pregnancy do not improve outcomes in women with a history of unexplained recurrent miscarriages.

The study of 826 women with previously unexplained recurrent miscarriage showed that those who received progesterone treatment in early pregnancy were no less likely to miscarry than those who received a placebo. This was true whatever their age, ethnicity, medical history and pregnancy history.

Smoking high potency 'skunk-like' cannabis can damage a crucial part of the brain responsible for communication between the two brain hemispheres, according to a new study.

Researchers have known for some time that long-term cannabis use increases the risk of psychosis and recent evidence suggests that alterations in brain function and structure may be responsible for this greater vulnerability. 

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most commonly diagnosed childhood disorders and can continue through adolescence into adulthood. Diagnoses exploded in the 1990s and now it is found in about 5% of children, but such diagnosis is based on clinical judgment rather than objective diagnostic markers. Symptoms include difficulty focusing attention and remaining "on task", impulsive behavior and extreme hyperactivity but some diagnoses have been made even when those behaviors were mild, so chemical interventions should be cautiously - but they are not.

Kids and teens who take medications like Ritalin to treat attention-deficit hyperactivity disorder are also twice as likely to be physically or emotionally bullied by peers. At even higher risk were middle and high school students who sold or shared their medications--those kids were four-and-a-half times likelier to be victimized by peers.

The main findings are the same for both sexes, said the study's first author, Quyen Epstein-Ngo, research assistant professor in gender studies at the University of Michigan. 

A paper in the Canadian Journal of Cardiology warns that the use of unvalidated natural "medicine" may lead to severe poisoning.

A 45-year-old Chinese woman was diagnosed with a severe heart-rhythm disorder, bidirectional ventricular tachycardia (BVT), associated with aconitine poisoning. BVT is a rare form of tachycardia (characterized by a resting heart rate over 100 beats per minute) and a distinct pattern of ECG waves on presentation.

Smokeless tobacco is used far less than cigarettes, primarily among men and young people, but it has become a cause for concern due to links with adverse health effects and identification as a cause of cancer.

Survey results and biomarkers published in Cancer Epidemiology, Biomarkers&Prevention, a journal of the American Association for Cancer Research, find that U.S. adults who used only smokeless tobacco products had higher levels of biomarkers of exposure to nicotine and a cancer-causing toxicant -- the tobacco-specific nitrosamine NNK -- compared with those who only used cigarettes.

Warning labels on medications about the dangers of driving don't stop people from getting behind the wheel, according to Dr Tanya Smyth, from the Queensland University of Technology   Centre for Accident Research&Road Safety.

Driving while affected by prescription and over-the-counter medications had the potential to be as dangerous as driving under the influence of illegal drugs. Medication warning labels and accompanying pharmacist advice were the primary method to control drug driving but required the user to self-assess their impairment.

Good news for space travelers on medication - expiration dates aren't different in the low orbit of the International Space Station (ISS). 

While the ISS is regularly resupplied with medicines to replace those which have passed their expiry date, this may not be possible on exploration missions that travel to more distant points. On Earth, medicines degrade over time, particularly when exposed to light, oxygen, or humidity. Although temperature and humidity conditions on board the ISS are generally within ideal ranges for medicine storage on Earth, until now, there has been little evidence of how medicines might react to factors unique to spaceflight, such as microgravity and constant exposure to elevated radiation levels.

The opioid addiction for more than half of female methadone clinic patients began with painkillers prescribed by doctors, according to a paper in Biology of Sex Differences.

More than half (52%) of women and a third (38%) of men reported doctor-prescribed painkillers as their first contact with opioid drugs, a family of drugs which include prescription medicines such OxyContin and codeine, as well as illicit drugs such as heroin.
