A smartphone application using the phone's camera function performed better than traditional physical examination to assess blood flow in a wrist artery for patients undergoing coronary angiography, according to a randomized trial published in CMAJ (Canadian Medical Association Journal).
TORONTO, April 3, 2018 -- Carbohydrates get a lot of bad press and blame for the obesity epidemic, but a new study suggests that this negative attention may not be deserved for pasta.
Unlike most 'refined' carbohydrates, which are rapidly absorbed into the bloodstream, pasta has a low glycemic index, meaning it causes smaller increases in blood sugar levels than those caused by eating foods with a high glycemic index.
Norwegians love to heat with wood. That's easy to see when driving around the Norwegian countryside in the winter. Stacks of wood line the walls of houses and smoke rises from the chimneys, especially on cold days.
There was even a national "wood night program" on NRK, the Norwegian Broadcasting Corporation, which ran for 12 hours and attracted international attention because of its unusual theme.
Every human cell is encased in a five-nanometer-thick lipid membrane that protects it from the surrounding environment. Like a gatekeeper, the membrane determines which ions and molecules can pass through. In so doing, it ensures the cell's well-being and stability and allows it to communicate via electrical signals.
Key takeaways:
Black-white disparities in hospital readmission rates in the U.S. narrowed after the introduction of a Medicare program that penalizes higher-than-expected readmissions.
Minority-serving hospitals continue to disproportionately receive penalties for their readmission rates, suggesting that more work needs to be done to ensure that pay-for-performance programs promote greater equity in care.
Satellite imagery showed that Tropical Cyclone Jelawat had developed an eye as it strengthened into a Super Typhoon.
On March 30, Jelawat was moving through the Philippine Sea. At 11 a.m. EST (1500 UTC) Jelawat was a hurricane with maximum sustained winds near 150 mph (130 knots/241 kph). The center of circulation was near 17.1 degrees north latitude and 139.5 degrees east longitude, approximately 384 nautical miles west-northwest of Andersen Air Force Base. Jelawat has tracked east-northeastward at 12.6 mph (11 knots/20.3 kph).
By learning how water is collected by living organisms, including rice leaves and pitcher plants, scientists at The University of Texas at Dallas created and tested a combination of materials that can do the same thing, but faster.
The iconic cone-like structure of Mount Etna could have been created after water levels in the Mediterranean Sea rose following an extended period of deglaciation, according to new research.
A study by Iain Stewart, Professor of Geoscience Communication at the University of Plymouth, explores changes in the volcano's structures which began around 130,000 years ago.
Scientists have previously said the switch from a fissure-type shield volcano to an inland cluster of nested stratovolcanoes was caused by a tectonically driven rearrangement of major border faults.
CHAMPAIGN, Ill. -- Bacteria in tap water can multiply when a faucet isn't used for a few days, such as when a house is vacant over a week's vacation, a new study from University of Illinois engineers found. The study suggests a new method to show how microbial communities, including those responsible for illnesses like Legionnaires' disease, may assemble inside the plumbing systems of homes and public buildings.
The findings are published in Nature's ISME Journal: Multidisciplinary Journal of Microbial Ecology.
Philadelphia, March 29, 2018 - The thrill of a hockey victory may put younger men at an increased risk for heart attack. A new study published in the Canadian Journal of Cardiology found an increase in hospital admissions for men under 55 presenting with symptoms of ST-elevation myocardial infarction (STEMI) or heart attack the day after a Montreal Canadiens win.
PITTSBURGH, March 29, 2018 - In response to repeated calls for an integrated and coordinated emergency and trauma care system in the U.S., University of Pittsburgh School of Medicine scientists and UPMC physicians rose to the challenge and divided the nation into hundreds of referral regions that describe how patients access advanced care, in a way that respects geopolitical borders.
AUGUSTA, Ga. (March 29, 2018) - A single high-fat milkshake, with a fat and calorie content similar to some enticing restaurant fare, can quickly transform our healthy red blood cells into small, spiky cells that wreak havoc inside our blood vessels and help set the perfect stage for cardiovascular disease, scientists report.
MINNEAPOLIS - A new study looks at what problems affect people most after a stroke and it provides a broader picture than what some may usually expect to see. Stroke affects more than just physical functioning, according to a study is published the March 28, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Some stage III colon cancer patients can cut in half the number of chemotherapy treatments they receive after surgery, significantly reducing the costs, treatment time, and long-term toxic effects of chemotherapy, according to results of a unique global clinical trial collaboration published for the first time in the New England Journal of Medicine.
SAN ANTONIO, Texas, U.S.A.--An international team led by Dr. Patricia Dahia, M.D., Ph.D., of UT Health San Antonio, discovered a genetic mutation that explains why adults with severe congenital heart defects--who live with low oxygen in their blood--are at dramatically high risk for adrenal gland cancer.
The finding is being made public March 29 in the New England Journal of Medicine.
