Studies: Oral Liquid Salt Choline & Geranate (CAGE) Blocks Fat Absorption W/ 12% Weight Loss (Harvard)

From a Harvard news release:

Harvard John A. Paulson School of Engineering and Applied Sciences…a new study from the Harvard John A. Paulson School for Engineering and Applied Sciences (SEAS) and Harvard’s Wyss Institute for Biologically Inspired Engineering has found that an orally administered liquid salt called Choline and Geranate (CAGE) can physically reduce the absorption of fats from food with no discernible side effects in rats, and reduces total body weight by about 12 percent.

CAGE Harvard Study“A reduction in body weight of 12 percent is like getting a human from 200 pounds down to 176, which is a significant change,” said first author Md Nurunnabi, a former Postdoctoral Fellow at the Wyss Institute and SEAS who is now an Assistant Professor of Pharmaceutical Sciences at The University of Texas at El Paso. “Our goal is to translate this work into a product that can help people maintain a healthier weight, and this study marks the very beginning of that journey.”

CAGE, which is a salt in its liquid state, was created a few years ago by Samir Mitragotri, the Hiller Professor of Bioengineering and Hansjörg Wyss Professor of Biologically Inspired Engineering, as part of an effort to improve the body’s absorption of medicines.

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.

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.

Engineering In Nature: “Honeybees Use Their Wings For Water Surface Locomotion” (Caltech)

From a Caltech online article:

Bees Surf Atop Water to escape CaltechWhen a bee lands on water, the water sticks to its wings, robbing it of the ability to fly. However, that stickiness allows the bee to drag water, creating waves that propel it forward. In the lab, Roh and Gharib noted that the generated wave pattern is symmetrical from left to right. A strong, large-amplitude wave with an interference pattern is generated in the water at the rear of the bee, while the surface in front of the bee lacks the large wave and interference. This asymmetry propels the bees forward with the slightest of force—about 20 millionths of a Newton.

Walking on Caltech’s campus, research engineer Chris Roh (MS ’13, PhD ’17) happened to see a bee stuck in the water of Millikan Pond. Although it was a common-enough sight, it led Roh and his advisor, Mory Gharib (PhD ’83), to a discovery about the potentially unique way that bees navigate the interface between water and air.

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.

Brain Health: “Package Of Lifestyle Changes” (Brisk Exercise, Healthy Diet & Sleep, Cognitive Training) Helps Prevent Dementia

From a Wall Street Journal online article:

How Likely is Dementia - Source The Lancet, Gill Livingston, et al.
How Likely Is Dementia?

Dementia is a complicated disease that has multiple causes and risk factors, some of which remain unknown. Nevertheless, there is increasing evidence that people—even those who inherit genes that put them at greater risk of developing Alzheimer’s in later life—can improve their chances by adopting lifestyle changes.

“It’s not just about running three times a week,” says Sarah Lenz Lock, executive director of AARP’s Global Council on Brain Health. “Instead, it’s about a package of behaviors, including aerobic exercise, strength training, a healthy diet, sleep and cognitive training.”

When it comes to battling dementia, the unfortunate news is this: Medications have proven ineffective at curing or stopping the disease and its most common form, Alzheimer’s disease. But that isn’t the end of the story. According to a recent wave of scientific studies, we have more control over our cognitive health than is commonly known. We just have to take certain steps—ideally, early and often—to live a healthier lifestyle.

In fact, according to a recent report commissioned by the Lancet, a medical journal, around 35% of dementia cases might be prevented if people do things including exercising and engaging in cognitively stimulating activities. “When people ask me how to prevent dementia, they often want a simple answer, such as vitamins, dietary supplements or the latest hyped idea,” says Eric Larson, a physician at Kaiser Permanente in Seattle and one of a group of scientists who helped prepare the report. “I tell them they can take many common-sense actions that promote health throughout life.”

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.

Health Reports: CDC Finds That 35,000 Americans Die Of Antibiotic-Resistant Infections Each Year

CDC Antibiotic Resistance Threats in the United States 2019More than 2.8 million antibiotic-resistant infections occur in the United States each year, and more than 35,000 people die as a result. In addition, nearly 223,900 people in the United States required hospital care for C. difficile and at least 12,800 people died in 2017.

Germs continue to spread and develop new types of resistance, and progress may be undermined by some community-associated infections that are on the rise. More action is needed to address antibiotic resistance. While the development of new treatments is one of these key actions, such investments must be coupled with dedicated efforts toward preventing infections in the first place, slowing the development of resistance through better antibiotic use, and stopping the spread of resistance when it does develop to protect American lives now and in the future.

CDC’s Antibiotic Resistance Threats in the United States, 2019 (2019 AR Threats Report) includes updated national death and infection estimates that underscore the continued threat of antibiotic resistance in the United States. New CDC data show that while the burden of antibiotic-resistance threats in the United States was greater than initially understood, deaths are decreasing since the 2013 report. This suggests that U.S. efforts—preventing infections, stopping spread of bacteria and fungi, and improving use of antibiotics in humans, animals, and the environment—are working, especially in hospitals. Vaccination, where possible, has also shown to be an effective tool of preventing infections, including those that can be resistant, in the community.

Exercise Studies: Older Adults’ “Fragmented Physical Exercise” Linked To Higher Death Rates

From a National Institute On Aging release:

Baltimore Longitudinal Study of Aging Studies
Baltimore Longitudinal Study of Aging Studies

Fragmented physical activity, but not total daily activity, was significantly associated with death, the researchers found. For each 10% higher degree of activity fragmentation, mortality risk was 49% greater. The duration of physical activity also mattered: Participants who frequently engaged in short bouts of activity of less than five minutes were more likely to die than those whose activity bouts lasted five minutes or longer. These associations held after adjusting for age, sex, body mass index and other factors.

Daily physical activity, which benefits health and quality of life, typically decreases in older adults. A new study shows that higher fragmentation of that activity — more transitions from activity to sedentariness — may be a better indicator of risk of death than a person’s overall level of physical activity.

Researchers from the Johns Hopkins Bloomberg School of Public Health, Baltimore, analyzed data from the NIA-supported Baltimore Longitudinal Study of Aging (BLSA), looking at a week’s worth of minute-by-minute physical activity for 548 healthy participants age 65 and older (average age, 76).
