Aspirin Lowers Stroke Risk In Women With History Of Preeclampsia

A new study suggests aspirin may lower stroke risk among middle-aged women with a history of preeclampsia. Middle-aged women with a history of preeclampsia have a greater risk of stroke, and aspirin may be able to reduce the risk, according to a new study led by researchers at Columbia University Vagelos College of Physicians & Surgeons. The study was published today in the journal Neurology, along with an accompanying editorial and podcast.

Opioid Overdose: FDA Moves to Fast-Track OTC Naloxone

The US Food and Drug Administration (FDA) announced "unprecedented" steps to support companies in developing over-the-counter (OTC) naloxone to help reduce opioid overdose deaths."With the number of overdose deaths involving prescription and illicit opioids more than doubling over the last 7 years to nearly 48,000 in 2017, it's critical that we continue to address this tragedy from all fronts," FDA Commissioner Scott Gottlieb, MD, said in a statement.

Risk Of Food Poisoning From Listeria monocytogenes

APC Microbiome Ireland scientists based at University College Cork have shown for the first time that a high fat "western" diet reduces the efficiency of the immune system to fight infectious disease particularly in the gut, and to infection with the foodborne pathogen, Listeria monocytogenes. The researchers found that feeding mice with a "westernised" diet, which is high in fat and low in fermentable fibre, affected both the immune system and the bacteria resident in the gut (the gut microbiota).

For Reproductive Success, Staying In Shape Is Vital

Cells must keep their shape and proportions to successfully reproduce through cell division, finds new research from the Francis Crick Institute and King's College London. The research, published in Nature Communications, reveals a fundamental biological basis for scaling, where cells maintain their proportions as they grow or shrink. This principle is seen throughout life, from single cells through to complex organisms, but its biological origins have remained a mystery.

Brain Vital Signs Detect Neurophysiological Impairments In Players

A team of Canadian and U.S. brain researchers have published results from a multi-year hockey concussion study, which tracked the brain function of young Junior A male ice hockey players using a new brainwave monitoring method called "brain vital signs." The peer-reviewed study is published online, and will be featured as an "Editor's Choice" in the February issue of "Brain: A Journal of Neurology", published by the Oxford University Press.

Text Message To Truck Drivers: For HIV Self-testing

Truck drivers in sub-Saharan Africa are especially vulnerable to infection with HIV due to contact with multiple sexual partners—often including sex workers—along their trucking routes. Accessing HIV testing can be a challenge for truckers due to their mobility and long working hours, as well as concerns about confidentiality and stigma.

For Health Insurance Premiums: Expect Govt To Revise 80D Limits

Medical inflation is growing at 14-16% every year and the healthcare expenses of the average household can easily exceed the medical allowance limit of Rs15,000 per annum. Companies usually cap the medical allowances at the tax-free limit of Rs15,000. The Union Budget 2019-20 holds many expectations even as India's domestic economy is going through a critical phase of growth.

New-style Packs: The Message Of Dangers Of Smoking Is More Effective

Smokers once used to turn a blind eye to health warnings on cigarette packets. But now researchers at the University of Huddersfield have used eye-tracking technology to prove that new-style packs have shifted the focus so that the message about the dangers of smoking is getting through more effectively.

Regulations introduced in the UK in 2016 insist that health warnings – consisting of text and pictures – must occupy 65 per cent of the front and back of cigarette and tobacco packaging. The names of the manufacturer and the brand must also now be printed in a low key, standardised style, against a drab brown background.
