A new study has found that people with chronic obstructive pulmonary disease (COPD) experience cardiac autonomic dysfunction, meaning that the heart's ability to speed up during exercise and recover afterwards is limited, regardless of disease severity. "Although it is a respiratory disease, COPD also affects other systems of the body," commented Laura Delgado, predoctoral researcher at ISGlobal. "Its effect on the cardiovascular and muscular system has been extensively studied, but its effect on the autonomic nervous system has received less attention." The study assessed participants' ability to increase their heart rate during exercise (chronotropic response, CR) and return to baseline...

…[A] team of scientists working with a Harvard graduate student is for the first time applying deep learning — a powerful new version of the machine learning form of AI — to forecast sudden disruptions that can halt fusion reactions and damage the doughnut-shaped tokamaks that house the reactions. Unlike traditional software, which carries out prescribed instructions, deep learning learns from its mistakes. Accomplishing this seeming magic are neural networks, layers of interconnected nodes — mathematical algorithms — that are “parameterized,” or weighted by the program to shape the desired output. For any given input the nodes seek to produce...

Paula Broadwell, the woman whose affair with then-CIA director David Petraeus cost him his job, has accused him of having her 'thrown under the bus' over their illicit relationship. The former intelligence officer said she felt 'betrayed' by Petraeus after news of their affair broke in 2012. 'I was in such a state of mental shock and quickly spiraled into a depression,' she told Vanity Fair.

The Canadian dollar has posted gains on Monday session, continuing the upward trend which marked the Friday. USD/CAD is trading at 1.2860. The Canadian dollar posted strong gains on Friday, which was somewhat surprising as Canadian markets were closed for Canada Day. US markets are closed on Monday for Independence Day, so there are no scheduled US events. Canada will publish Manufacturing PMI and the BoC Business Outlook Survey. With the financial markets understandably focused on the stunning Brexit vote, the Federal Reserve’s monetary policy has shifted to the back-burner. That could change later this week, with the release of...

The AH-64A/D Apache and AH-64E Block III Apache Longbow (renamed Guardian) are four-blade twin-engine attack helicopters manufactured by Boeing. The Apache was originally developed by Hughes Helicopters in the 1970s (first flight on September 30, 1975), however, the company was acquired by McDonnell Douglas in 1984. In 1997, McDonnell Douglas merged with Boeing. The latest variant, the AH-64E Apache Guardian helicopter (originally designated AH-64D Block III), is powered by two General Electric T700-GE-701D turboshaft engines with 1,994 shp each. The AH-64D/E models are based on the original AH-64A, which was deployed in 1984 and first used in combat in 1989...

Baltimore Ravens fans gave running back Ray Rice a standing ovation as he jogged onto the field during training camp practice on Monday, according to the team's website. Rice acknowledged the cheering fans by pointing to the crowd. Rice was seen on video in February dragging his then-fiancée out of an Atlantic City casino elevator. He was charged with third-degree aggravated assault after Janay Palmer, whom he later married, was left unconscious following the incident. Rice agreed to enter into a diversion program to avoid a jail sentence. More: Lenient penalty for Ray Rice troubling proof of where NFL's priorities...

History of Gestational Diabetes Mellitus and Future Risk of Atherosclerosis in Midâ€life: The Coronary Artery Risk Development in Young Adults Study Gestational diabetes can be controlled with meal planning, activity and occasionally insulin or other types of medications. Science Recorder | James Fluere | Friday, March 14, 2014 According to a statement from the American Heart Association, gestational diabetes — a condition characterized by high blood sugar levels that is first recognized during pregnancy — may increase risk for heart disease in midlife. Fortunately, the condition can be controlled with meal planning, activity and occasionally insulin or other types of...

(Updated with a response from Dr. Maria Grazia Modena) New questions are being raised about the integrity and reliability of research published by a prominent Italian cardiologist and her colleagues. Last November, as previous reported here, Maria Grazia Modena, a former president of the Italian Society of Cardiology, and 8 other Italian cardiologists were arrested as part of a broad investigation into serious medical misconduct at Modena Hospital. To date the Italian authorities have not issued any indictments, but at least one aspect of the investigation appears to involve unauthorized research and failing to obtain informed consent from patients in...

(CNSNews.com) – As part of his ongoing campaign to transform New York City into what he calls “Fit City,” Mayor Michael Bloomberg is promoting “active design” for low-income housing developments being built there, including plans to prompt residents to use the stairs and rooftop gardens for growing “healthy” foods. In 2010, the Bloomberg Administration and other public and private sector groups issued the “Active Design Guidelines,” which promotes car-free neighborhoods, encourages “physical movement” inside buildings and “improves access to nutritious food.”The Center for Action Design was launched next as a resource for architects and developers who sign on to the...

She was a 32-year-old aerobics instructor from a Dallas suburb — healthy, college-educated, with two young children. Nothing out of the ordinary, except one thing. Her cholesterol was astoundingly low. Her low-density lipoprotein, or LDL, the form that promotes heart disease, was 14, a level unheard-of in healthy adults, whose normal level is over 100. The reason: a rare gene mutation she had inherited from both parents. Only one other person, a young, healthy Zimbabwean woman whose LDL cholesterol was 15, has ever been found with the same mutation. The discovery of the mutation and of the two women with...

In a multiethnic group of adults, low serum 25-hydroxyvitamin D concentration was associated with increased risk of coronary heart disease events among white or Chinese participants but not among black or Hispanic participants, results that suggest that the risks and benefits of vitamin D supplementation should be evaluated carefully across race and ethnicity, according to a study in the July 10 issue of JAMA. "Low circulating concentrations of 25-hydroxyvitamin D (25[OH]D) have been consistently associated with increased risk of clinical and subclinical coronary heart disease (CHD). Whether this relationship is causal and modifiable with vitamin D supplementation has not yet...

Drugs that are used for treating Alzheimer's disease in its early stages are linked to a reduced risk of heart attacks and death, according to a large study of over 7,000 people with Alzheimer's disease in Sweden.The research, which is published online today (Wednesday) in the European Heart Journal [1], looked at cholinesterase inhibitors (ChEIs), such as donepezil, rivastigmine and galantamine, which are used for treating mild to moderate Alzheimer's disease [2]. Side-effects of ChEIs include a beneficial effect on the vagus nerve, which controls the rate at which the heart beats, and some experimental studies have suggested that ChEIs...

In the 2008 Pixar movie WALL.E, humans so clogged up the earth with garbage they had to move to spaceships. Motorized chairs ferried the obese blobs portraying people of the future, who sipped liquids from massive cups and sat mesmerized by video screens. It was both funny and scary in its assessment of America’s throw-away, fast-food culture where convenience is everything and self-control and direction outsourced to technology. At the time of the movie it was part of an emerging chorus of voices decrying Americans’ growing girth. Five years later it is almost impossible to go a day without seeing...

Another large study has failed to find any benefits for fish oil supplements. The Italian Risk and Prevention Study, published in the New England Journal of Medicine, enrolled 12,513 people who had not had a myocardial infarction but had evidence of atherosclerosis or had multiple cardiovascular risk factors. The patients were randomized to either a fish oil supplement (1 gram daily of n-3 fatty acids) or placebo. After 5 years of followup, the primary endpoint– the time to death from cardiovascular causes or admission to the hospital for cardiovascular causes– had occurred in 11.7% of the fish oil group versus...

Our guts are awash in bacteria, and now a new study fingers them as culprits in heart disease. A complicated dance between the microbes and a component of red meat could help explain how the food might cause atherosclerosis. The work also has implications for certain energy drinks and energy supplements, which contain the same nutrient that these bacteria like chasing after. Red meat is considered bad news when it comes to heart health, although studies aren't consistent about how much can hurt and whether it always does. Furthermore, it's not clear which components of meat are doing harm. Various...

Gut bacteria may convert a nutrient found in red meat into a compound that can damage the heartThe link between red meat and poor heart health has traditionally been blamed on cholesterol, but new evidence suggests this isn't the whole story. US researchers found that carnitine, a nutrient found in red meat, is converted into a metabolite that promotes cardiovascular disease by gut bacteria. This may mean that the popular practice of taking carnitine supplements to build muscle is unwise.‘The cholesterol and saturated fat content of red meat is not sufficient to account for increased cardiac risk,’ says lead author...

Revised guidelines for heart health are set to move away from target-based approach. Soon after Joseph Francis learned that his levels of ‘bad’ LDL cholesterol sat at twice the norm, he discovered the shortcomings of cholesterol-lowering drugs — and of the clinical advice guiding their use. Francis, the director of clinical analysis and reporting at the Veterans Health Administration (VA) in Washington DC, started taking Lipitor (atorvastatin), a cholesterol-lowering statin and the best-selling drug in pharmaceutical history. His LDL plummeted, but still hovered just above a target mandated by clinical guidelines. Adding other medications had no effect, and upping the...
