Health Study: Death From Heart Disease Four Times Higher In Women With “Poor Exercise Capacity”

From a European Society of Cardiology online release:

European Society of Cardiology ESCThe annual rate of death from cardiovascular disease was nearly four times higher in women with poor, compared to good, exercise capacity (2.2% versus 0.6%). Annual cancer deaths were doubled in patients with poor, compared to good, exercise capacity (0.9% versus 0.4%). The annual rate of death from other causes was more than four times higher in those with poor, compared to good, exercise capacity (1.4% vs. 0.3%).

Women who can exercise vigorously are at significantly lower risk of dying from heart disease, cancer and other causes. The research is presented today at EuroEcho 2019, a scientific congress of the European Society of Cardiology (ESC).1

During a median follow-up of 4.6 years there were 345 cardiovascular deaths, 164 cancer deaths, and 203 deaths from other causes. After adjusting for factors that could influence the relationship, METs were significantly associated with lower risk of death from cardiovascular disease, cancer, and other causes.

Health Studies: Lifelong Exercise Promotes “Anti-Inflammation” In Skeletal Muscle (Physiology.org)

From a Journal of Applied Physiology online abstract:

Journal of Applied PhysiologyThus, while aging led to a pro-inflammatory profile within blood and muscle, lifelong exercise partially prevented this and generally preserved the acute inflammatory response to exercise seen in young exercising men. Lifelong exercise may positively impact muscle health throughout aging by promoting anti-inflammation in skeletal muscle.

From a New York Times article review of study:

Taken as a whole, these results suggest that long-term exercise may help aging muscles remain healthy in part by readying them to dissipate inflammation, Dr. Trappe says. But on the flip side, sedentary living seems to set up muscles to overreact to strain and remain inflamed, potentially leading to fewer muscular gains when someone does exercise.

Studies: “Blood-Based ‘Liquid Health Check’ Beats Traditional Predictors of Multiple Disease Risks” (Nature)

From a Genetic Engineering & Biotechnology News release:

Nature Medicine Journal Dec 2019“This proof of concept study demonstrates a new paradigm that measurement of blood proteins can accurately deliver health information that spans across numerous medical specialties and that should be actionable for patients and their healthcare providers,” said Peter Ganz, MD, co-leader of this study and the Maurice Eliaser distinguished professor of medicine at UCSF and director of the Center of Excellence in Vascular Research at Zuckerberg San Francisco General Hospital and Trauma Center. 

Specific patterns of protein levels in our blood could be used to provide a comprehensive “liquid health check” that gives a snapshot of health and potentially an indication of the likelihood that we will develop certain diseases or health risk factors in the future, according to research by scientists in the U.S. and U.K. working with SomaLogic. The results of their proof-of-concept study involving more than 16,000 participants, and published in Nature Medicine, showed that while the accuracy of models based on specific protein expression patterns varied, they were all either better predictors than models based on traditional risk factors, or would constitute more convenient and less expensive alternatives to traditional testing.

Health Studies: Foods Containing Lactose Feed “Dangerous” Gut Bacteria

From Sloan Kettering Institute:

Enterococcus BacteriaInfections with the Enterococcus bacterium are a major threat in healthcare settings. They can lead to inflammation of the colon and serious illnesses such as bacteremia and sepsis, as well as other complications.

Now, an international team led by scientists from Memorial Sloan Kettering has shown for the first time that foods containing lactose, a sugar that’s naturally found in milk and dairy products, help Enterococcus thrive in the gut, at least in mice. They also studied changes in the bodies of people having BMTs. The study was published November 29 in Science.

Memorial Sloan KetteringTheir previous research has shown that when harmless strains of microbes are wiped out, often due to treatment with antibiotics, Enterococcus and other harmful types of bacteria can take over due to lack of competition. As part of the new study, which included analysis of microbiota samples from more than 1,300 adults having BMTs, the team confirmed the link between Enterococcus and GVHD.

Health Studies: Eating After Exercise Found To Burn “Twice The Fat”

From a New York Times online article:

Journal of Clinical Endocrinology & MetabolismThe riders who had pedaled on an empty stomach, however, had incinerated about twice as much fat during each ride as the men who consumed the shake first. The riders all had burned about the same number of calories while pedaling, but more of those calories came from fat when the men did not eat first.

Those riders also showed greater improvements in insulin sensitivity at the end of the study and had developed higher levels of certain proteins in their muscles that influence how well muscle cells respond to insulin and use blood sugar.

Working out on an empty stomach could amplify the health benefits of the activity, according to a well-timed new study of the interplay of meal timing, metabolic health and moving. The study, which involved sedentary men and moderate cycling, suggests that whether and when we eat may affect how exercise affects us.

Studies: High Usage Of Commonly Used Oral Antibiotics Increases Risk Of Parkinson’s Disease

From a Neuroscience News & Research online article:

International Parkinson and Movement Disorder Society“The link between antibiotic exposure and Parkinson’s disease fits the current view that in a significant proportion of patients the pathology of Parkinson’s may originate in the gut, possibly related to microbial changes, years before the onset of typical Parkinson motor symptoms such as slowness, muscle stiffness and shaking of the extremities. It was known that the bacterial composition of the intestine in Parkinson’s patients is abnormal, but the cause is unclear. Our results suggest that some commonly used antibiotics, which are known to strongly influence the gut microbiota, could be a predisposing factor,” says research team leader, neurologist Filip Scheperjans MD, Ph.D. from the Department of Neurology of Helsinki University Hospital.

Higher exposure to commonly used oral antibiotics is linked to an increased risk of Parkinson’s disease according to a recently published study by researchers from the Helsinki University Hospital, Finland.

The strongest associations were found for broad-spectrum antibiotics and those that act against anaerobic bacteria and fungi. The timing of antibiotic exposure also seemed to matter.

The study suggests that excessive use of certain antibiotics can predispose to Parkinson’s disease with a delay of up to 10 to 15 years. This connection may be explained by their disruptive effects on the gut microbial ecosystem.

Health: “Feather Duvet Lung” Left Undiagnosed Risks Irreversible Lung Fibrosis (BMJ Case Reports)

From a British Medical Journal (BMJ) online release:

Feather Duvet LungAlthough he had no pet birds, on closer questioning he had recently acquired a duvet and pillows containing feathers. His symptoms, chest radiograph and lung function tests improved after removal of all feather bedding, and he was also started on oral corticosteroid therapy. Our case reinforces the importance of taking a meticulous exposure history and asking about domestic bedding in patients with unexplained breathlessness. Prompt recognition and cessation of antigen exposure may prevent the development of irreversible lung fibrosis.

A 43-year-old non-smoker was referred with a 3-month history of malaise, fatigue and breathlessness. Blood avian precipitins were strongly positive. Lung function testing confirmed a restrictive pattern with impaired gas transfer. A ‘ground glass’ mosaic pattern was seen on CT imaging, suggestive of hypersensitivity pneumonitis.

Feather duvet lung (FDL), is an immunologically mediated form of hypersensitivity pneumonitis (HP), also sometimes called extrinsic allergic alveolitis. FDL is caused by inhalation of organic dust from duck or goose feathers found in duvets and pillows. Antigen inhalation triggers an immunological cascade, resulting in lung parenchymal inflammation. Repeated exposure may result in irreversible lung fibrosis.

Health Studies: NSAIDs (Nonsteroidal Anti-Inflammatory Drugs) Increase Heart Failure Risk For Arthritis Patients

From a Harvard Medical School release:

Harvard Medical SchoolResearchers matched 7,743 people with osteoarthritis with 23,229 healthy people who rarely or never took NSAIDs. People with osteoarthritis had a 42% higher risk of heart failure and a 17% higher risk of coronary artery disease compared with healthy people. After controlling for a range of factors that contribute to heart disease (including high body mass index, high blood pressure, and diabetes), they concluded that 41% of the increased risk of heart disease related to osteoarthritis was due to the use of NSAIDs.

To manage the painful joint disease known as osteoarthritis, people often take ibuprofen (Advil, Motrin) and naproxen (Aleve, Anaprox). But these and related drugs — known as NSAIDs — may account for the higher rates of heart disease seen in people with osteoarthritis, a new study suggests.

Health Studies: Reduced Mental Alertness (“Brain Fog”) Is Caused By Inflammation In The Body

From a Genetic Engineering & Biotechnology News release:

NeuroImage Journal“These results show quite clearly that there’s a very specific part of the brain network that’s affected by inflammation,” noted Mazaheri. “This could explain ‘brain fog’.”

Raymond added that “this research finding is a major step forward in understanding the links between physical, cognitive, and mental health and tells us that even the mildest of illnesses may reduce alertness.”

Researchers at the University of Birmingham’s Centre for Human Brain Health in collaboration with the University of Amsterdam say they have uncovered a possible explanation for the mental sluggishness that often accompanies illness. The team investigated the link between “mental fog” and inflammation, the body’s response to illness. In a study (“Selective effects of acute low-grade inflammation on human visual attention”) published in Neuroimage, they showed that inflammation appears to have a particularly negative impact on the brain’s readiness to reach and maintain an alert state.

Heart Disease: Stents, Bypass Surgery Provide No Benefits To Stable Patients In Large Funded Trial

From a Stanford Medicine online release:

Stent in Coronary Artery“For patients with severe but stable heart disease who don’t want to undergo these invasive procedures, these results are very reassuring,” said David Maron, MD, clinical professor of medicine and director of preventive cardiology at the Stanford School of Medicine, and co-chair of the trial, called ISCHEMIA, for International Study of Comparative Health Effectiveness with Medical and Invasive Approaches. 

“The results don’t suggest they should undergo procedures in order to prevent cardiac events,” added Maron, who is also chief of the Stanford Prevention Research Center.

Patients with severe but stable heart disease who are treated with medications and lifestyle advice alone are no more at risk of a heart attack or death than those who undergo invasive surgical procedures, according to a large, federally-funded clinical trial led by researchers at the Stanford School of Medicine and New York University’s medical school.

The trial did show, however, that among patients with coronary artery disease who also had symptoms of angina — chest pain caused by restricted blood flow to the heart — treatment with invasive procedures, such as stents or bypass surgery, was more effective at relieving symptoms and improving quality of life.
