From Sloan Kettering Institute:
Infections 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.
Their 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.

The 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.
“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.
Although 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.
When 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.
Researchers 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.
“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’.”
