How this pediatrician handles a distorted concept of reality [PODCAST]
“The victims of this now distorted concept of liberty are ones that we physicians encounter every day. The one that inspired this essay for me is an 11-year-old boy that I saw three weeks ago. He is a patient of mine in my pediatric practice who came to see me with typical respiratory symptoms thatRead more …How this pediatrician handles a distorted concept of reality [PODCAST] originally appeared inKevinMD.com.

Viral upper respiratory infections in the age of COVID
Your toddler has had a cough and runny, stuffy nose on and off for months. They also attend daycare and have a sibling in preschool. You are worried about the symptoms. You are also exhausted because your child’s coughing and congestion is not letting either of you sleep at night. Does this sound familiar?

Innovation, mRNA, and Public Policy
Chris EdwardsThe main weapons against COVID-19 are the vaccines developed by Moderna and BioNTech after a decade of their research into mRNA technologies. That research was supported by more than $3 billion of private angel investment and venture capital.Democrats and Republicans both support medical research funding, and Republicans tout the Trump administration ’s Operation Warp Speed. But governments were not the key to mRNA development. Instead, we can thank the leaders and scientists at Moderna and BioNTech and the suppliers of private capital to them, as I discusshere andhere.TheWall Street Journal ’s A...

In this study, they found these drugs can kill senescent cells from cultures of human fat tissue. The tissue was donated by individuals with obesity who were known to have metabolic troubles. Without treatment, the human fat tissues induced metabolic problems in immune-deficient mice. After treatment with dasatinib and quercetin, the harmful effects of the fat tissue were almost eliminated.

It ’ s not all Greek to me
By now, we’ve all heard the phrase “variant of concern” referring to a new form of the coronavirus that causes COVID-19. Technically, these variants have mutations that alter how well the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus infects our cells. If the new form of the virus is of concern it is usually because the mutations in the spike protein on the surface of the virus are likely to make it more infectious, faster spreading and/or to worse symptoms or lead to more deaths.
The national and international health organisations assess new variants of which there are known to be hu...

There is no quick fix for kids ’ cold and flu symptoms but there are things you can do
Colder weather is upon us again – and so is cold and flu season. Nearly two years into the fight against COVID-19, we welcome children returning to schools, daycare, and sports. But with the loosening of restrictions and increased social contacts, we are also now seeing increased circulation of common seasonal respiratory viruse s. Kids areRead more …There is no quick fix for kids’ cold and flu symptoms but there are things you can do originally appeared inKevinMD.com. (Source: Kevin, M.D. - Medical Weblog)

Airway Chip as Benchtop Model of Cystic Fibrosis
Researchers at Harvard’s Wyss Institute created a microfluidic chip that mimics the airway of patients with cystic fibrosis. By including lung airway cells from cystic fibrosis patients within the device, the team was able to reproduce many of the hallmarks of the disease, including a thick mucus layer, inflammation, and bacterial growth. The chip could provide the first advanced preclinical testing platform for cystic fibrosis treatments and increase our understanding of the disease.

Oral Bacteria and Age-Related Airway Inflammation
Researchers have in the past proposed links between oral bacteria and chronic inflammation, particularly in the heart and brain, proposing that bacterial toxins and bacteria themselves enter the bloodstream via damaged gums. This undoubtedly happens, but supporting data is mixed when it comes to the question of whether or not this has a meaningful effect size in comparison to other inflammatory mechanisms and contributions to age-related disease. Here, a different route for bacteria is proposed: passage into the airways and lungs, a possibly explanation as why gum disease and respiratory mortality are correlated in older p...

Vocal Biomarkers: New Opportunities in Prevention
Vocal biomarkers have amazing potential in reforming diagnostics. As certain diseases, like those affecting the heart, lungs, vocal folds or the brain can alter a person’s voice, artificial intelligence (A.I.)-based voice analyses provide new horizons in medicine. Using biomarkers for diagnosis and remote monitoring can also be used for COVID-screening. So is it possible to diagnose illnesses from the sound of your voice?
Let’s have a look at where this technology stands today.

More Data on Particulate Air Pollution as a Contributing Cause of Mortality
In this study, we investigated whether the type of fuel used for cooking is associated with subsequent 8-year mortality and whether switching the fuel used for cooking for 4 years is associated with changes in HR with successive 5 years of follow-up.
Among the participants in the 2011-2018 survey, 53% reported using solid fuel. Such group was associated with a 9% increase in mortality risk relative to clean fuel users (HR = 1.09). Among participants in the 2014-2018 survey, 339 reported a switch from solid to clean fuels and they were not at increased mortality risk relative to the 488 people that reported a stable ...

Chip for Investigation of Coronavirus Intestinal Infection
This study demonstrates that we can explore complex interactions between cells, pathogens, and drugs in the human intestine using our Intestine Chip as a preclinical model,” said Don Ingber, a researcher involved in the study, via a press release. “We hope it proves useful in the ongoing effort to better understand the effects of SARS-CoV-2 and to identify drugs that could be used to combat future viral pandemics.”
