51 members of the U.S. House of Representatives have signed a letter to the U.S. Drug Enforcement Agency (DEA) urging the federal agency to halt an emergency push to ban the analgesic herb kratom by as early as tomorrow. 

Researchers have clarified important mechanisms involved in the formation of neural circuits in the brain, and discovered that delta-9-tetrahydrocannabinol (THC), a psychoactive substance also found in cannabis, causes disruption of neural circuits within the cortex. 

Women who have high alcohol intake, 14 or more servings of alcohol a week are slightly more likely to have reduced fertility, suggests a study published in The BMJ today.

In developed countries, up to 24% of couples experience infertility, defined as time to pregnancy of 12 months or more. Official guidelines in countries like the USA, UK and Denmark recommend that women trying to become pregnant should abstain from alcohol consumption. But the extent to which alcohol intake affects female fertility is unclear. So a group of Danish researchers carried out a large prospective cohort study to examine the association between pre-conception alcohol consumption and time to pregnancy.

During the 2016, after 8 years of politicians refusing to work together, it may surprise you to learn that other groups do consult experts outside their own circles. It won't surprise you to learn a group of academics think that's a bad thing, and that cancer care guidelines should never meet with the companies that actually create cancer care.

Yet that's what the University of North Carolina Lineberger Comprehensive Cancer Center sets out to do, and does; they think that any consulting means scientists and doctors are for sale. 

A new study in Neurology associates calcium supplements with an increased risk of dementia in older women who have had a stroke or other signs of cerebrovascular disease. 
Calcium from food affects the body differently than calcium from supplements and is safe or even protective against vascular problems. 

Cerebrovascular disease is a group of disorders that affect blood flow in the brain. These diseases, including stroke, are the fifth leading cause of death in the United States and increase the risk of developing dementia.

The combination of two plant compounds that have medicinal properties - curcumin and silymarin - holds promise in treating colon cancer, according findings in the Journal of Cancer.

Curcumin is the active ingredient in the spice turmeric, which is present in spicy curry dishes, and silymarin is a component of milk thistle, which has been used to treat liver disease.

Last week, a press release reached me announcing that a Chinese herbal medicine called "Phynova Joint and Muscle Relief Tablets" and containing the active ingredient Sigesbeckia is now on sale in the UK for the first time, in Boots The Chemist: 
Sigesbeckia is the first traditional Chinese treatment granted a traditional herbal registration (THR) under the traditional herbal medicines product directive in the UK, by drug safety watchdog the Medicines and Healthcare Products Regulatory Agency (MHRA). Oxford based Phynova which manufactures the product was granted the UK licence last year.

Eating a powdered food supplement based on a molecule produced by bacteria in the gut, reduces cravings for high-calorie foods such as chocolate, cake and pizza, according to a small pilot study which asked 20 volunteers to consume a milkshake that either contained an ingredient called inulin-propionate ester, or a type of fiber called inulin.

Previous studies have found that bacteria in the gut release a compound called propionate when they digest the fiber inulin, which can signal to the brain to reduce appetite. However the inulin-propionate ester supplement releases much more propionate in the intestines than inulin alone.

MINNEAPOLIS - A drug commonly used to treat pain, epilepsy, anxiety and other brain health disorders may be associated with an increased risk of major birth defects, according to a study in Neurology

The drug pregabalin is approved by the FDA to treat epilepsy, fibromyalgia and neuropathic pain, such as pain from diabetic neuropathy or pain after shingles or spinal cord injury. It is also used for generalized anxiety disorder and other mental health issues. This is called off-label prescribing.

As I am new here, it might be a good idea to briefly introduce myself. I am a physician, trained in Germany, whose very first post as a freshly-backed doctor happened to be in Germany’s only homeopathic hospital. At the time (mid 1970s), I had no idea that this experience would determine so much of my professional life.

Subsequently, I became a conventional doctor until I risked a complete career change: I went to London and worked in a research laboratory. This is when I began to think as a scientist. Later, I returned to Germany, did a PhD and, for many years, worked simultaneously as a scientist as well as a clinician.
