The vast majority of so-called "super-frequent user" patients who seek care in the Emergency Department - a patient is considered a super-frequent user if they visit the emergency room at least 10 times a year  - have a substance abuse addiction, according to a Henry Ford Hospital analysis.

ER physicians have long said that patients who frequent the ER for their care have a substance abuse addiction but few studies have actually measured the rate of addiction of these patients.

The  findings presented Saturday at the Society for Academic Emergency Medicine (SAEM) annual meeting in Dallas found that super-frequent users seeking pain-relief narcotics were more often women. 

The study's key findings:

When most people think of modern birds they don't often picture dinosaurs - but that is the case. Dinosaurs rule the sky as they once ruled land and there are even modern raptors - eagles.

Athens, 17 May 2014: Negative iron balance predicts survival in patients with acute heart failure, according to research presented for the first time today at the Heart Failure Congress 2014 in Athens, Greece. The Congress is the main annual meeting of the Heart Failure Association of the European Society of Cardiology.

Professor Ewa Jankowska, first author of the study, said: "Patients with acute heart failure have a major collapse in homeostasis. Iron is a key micronutrient that is required for the maintenance of homeostasis. Iron is needed for cellular metabolism and deficiency leads to severely impaired energy metabolism and mitochondrial dysfunction."

The U.S. Food and Drug Administration (FDA) today allowed marketing of the DEKA Arm System, the first prosthetic arm that can perform multiple, simultaneous powered movements controlled by electrical signals from electromyogram (EMG) electrodes.

Deka calls it "Luke", after Luke Skywalker of "Star Wars" fame, and the project was funded by DARPA.

EMG electrodes detect electrical activity caused by the contraction of muscles close to where the prosthesis is attached. The electrodes send the electrical signals to a computer processor in the prosthesis that translates them to a specific movement or movements.

PHILADELPHIA — Young adults who smoked water pipes in hookah bars had elevated levels of nicotine, cotinine, tobacco-related cancer-causing agents, and volatile organic compounds (VOC) in their urine, and this may increase their risk for cancer and other chronic diseases, according to a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Massachusetts General Hospital (MGH) investigators have developed a transgenic mouse that synthesizes both the omega-3 and omega-6 essential fatty acids within its tissues on a diet of carbohydrates or saturated fats. Called "essential" because they are necessary to maintain important bodily functions, omega fatty acids cannot naturally be synthesized by mammals and therefore must be acquired by diet. Significant evidence suggest that the ratio of dietary omega-6 to omega-3 has important implications for human health, further increasing interest in the development of foods rich in omega-3s, which are found in certain species of fish as well as some nuts and green vegetables.
