Mosquitoes 'put off biting' by human diet drugs

Health
Scientists say they may have found a way to reduce the appetite of blood-hungry mosquitoes, by giving them human diet drugs.This left them feeling full and bloated and put them off biting, US researchers said.They said the technique could be used to prevent illnesses such as Zika, yellow fever and malaria.But their research is still in its early stages, the study in the journal Cell reports.The researchers, from Rockefeller University in New York City, conducted their experiments on Aedes aegypti mosquitoes. Female mosquitoes of this species - who are the only ones who bite - are fiercely attracted to human beings, because their blood contains the protein they need to produce their eggs.Once fed, that attraction to humans goes aw...
Common gut bacteria blocks effects of Parkinson's drugs, study says

Common gut bacteria blocks effects of Parkinson's drugs, study says

Health
Jan. 18 (UPI) -- A common gut bacteria can block a common Parkinson's disease medicine from working on patients with the disease, a new study says. Gut bacteria metabolizes levodopa, a common Parkinson's medication, into dopamine, a neurotransmitter in the brain. Since dopamine can't pass through the blood-brain barrier, it saps the levodopa of its effectiveness, according to a study published Friday in the journal Nature Communications. "It is well established that gut bacteria can affect the brain," Sahar El Aidy, an assistant professor in microbiology at University of Groningen and study lead investigator, said in a news release. "There is a continuous chemical dialogue between gut bacteria and the brain, the so-called gut-brain axis." The less effect a normal dosage of levodopa has on...
Trump signs bills to help patients stop overpaying for drugs

Trump signs bills to help patients stop overpaying for drugs

Health
Insurers will no longer be able to bar pharmacists from telling consumers when paying cash would be cheaper than using insurance for their prescriptions, as a result of bills signed Wednesday by President Donald Trump. The two bills had broad bipartisan support as a consumer-friendly move to correct "gag rules" that many viewed as an egregious business practice. One bill applies to private health insurance and the other to Medicare. The measures bar health plans or middlemen that manage pharmacy benefits from getting in between pharmacists and their customers. No longer can pharmacists be contractually prohibited from telling consumers when they would actually save money by not using their insurance plans. Such head-scratching situations can arise because of convoluted deals between drug...

Some drugs, supplements taken together can pose health risk

Health
Sept. 25 (UPI) -- People who use certain over-the-counter herbal medicines and dietary supplements concurrently with prescription drugs could open themselves up to serious health risks, especially among older adults, according to a study. Researchers in Britain found some drugs' effectiveness was reduced and that new medical problems could be caused with some combinations in a study published Monday in the British Journal of General Practice. They report that blood pressure treatments, statins and aspirin are affected, and there is increased blood glucose concentration and risk of bleeding. They also found the body's reduced ability to absorb prescription drugs associated with aging. Researchers found 32.6 percent of the participants were at risk of potential adverse drug interactions. S...

Media playback is unsupported on your device England's healthcare regulator is calling for a change in the law to protect patients using online doctor sites selling prescription-only drugs.
