Fluticasone-based inhaled corticosteroid treatment substantially changed airway microbiome diversity in patients with COPD, according to new data published in the American Journal of Respiratory and Critical Care Medicine.

“Inhaled corticosteroids . . . can change the microbial communities of airways of COPD patients, rendering them more susceptible for pneumonia,” Don D. Sin, MD, director and De Lazzari Family Chair at the Centre for Heart Lung Innovation, Canada Research Chair in COPD and professor of respiratory medicine, department of medicine at St. Paul’s Hospital, Vancouver, British Columbia, is quoted saying in Healio.

The study results according to the Healio report related to “reduced abundances of Pasteurellas, Pasteurellaceae and Haemophilus.” It also suggests that further studies are needed to determine “which bacterial organisms are responsible for keeping the microbiome airway healthy”.

According to a December 07 2022 article, Ferring Company developed a first-of-its-kind prototype biomarker algorithm that measures the positive and negative impact on our gut microbiome of using antibiotics.

The Ferring MHI-A algorithm differentiates post-antibiotic dysbiosis from healthy microbiota in the gut associated with healthy Bacteroidia and Clostridia, versus potentially harmful species such as Gammaproteobacteria and Bacilli.

Researchers at Ferring say MHI-A is a useful for rank-ordering the microbiota-disrupting effects of antibiotics and a measure of microbiota restoration. Ken Blount, Chief Scientific Officer, Rebiotix, Vice President Microbiome Research, Ferring Pharmaceuticals, is quoted by Business Wire as saying, “This biomarker provides a concise metric for assessing the complex changes in the microbiome of trial participants pre- to post-treatment.”

Nature is doing its own repairing with growth of plastic eating enzymes

thread
Scientists at the Chalmers University in Sweden that one in every four organisms in the microbiomes they studied carries a protein sequence for plastic-degrading enzymes, according to an article published December 16 2021 in The Nerdist.com.

Scientists identified locations where these plastic degrading microbiomes are growing in number alongside plastic pollution in the oceans. As to whether or not this development is keeping up with plastic pollution growth is still to be determined.

Autism tied to mother's microbiome

According to a December 08 2021 Genetic Engineering and Biotechnology News (Genengnews) article, autism spectrum disorder (ASD) can be sourced by inflammation in the mother's womb leading to gastrointestinal issues in the child.

Based on mouse models of autism used by scientists at Harvard (Medical School) and MIT (Massachusetts Institute of Technology), IL-17A not only changes the mother’s gut microbiome but it also alters brain development in the fetus, affecting the offspring’s immune system. This change in immune development primes the offspring for inflammatory attacks of the gut after birth, leading to neurodevelopmental and immunological symptoms (1).

The findings are based on mouse studies of IL-17a during pregnancy by Gloria Choi, PhD, associate professor at the department of brain and cognitive sciences at the Picower Institute for Learning and Memory at the Massachusetts Institute of Technology, and Jun Huh, PhD, associate professor of immunology, Harvard Medical School.

In related news in 2017, Rensselaer Polytechnic Institute discovered a new way to identify children on the autism spectrum based on concentrations of specific substances, folate-dependent one-carbon (FOCM) metabolism and transsulfuration (TS) pathways, found in their blood samples (2).

phenolic compounds in food aid in reducing free radicals; TCM dismissed by WebMD

phenolic compounds in food aid...
According to a mice study and other studies reported in Handawi on November 08 2021, phenolic compounds effectively reduced oxidative stress from the buildup of free radicals. Free radicals are known to lead to various diseases including cardiovascular diseases, diabetes, cancer, and neurodegenerative diseases (1).

Phenolic compounds have received considerable attention for their antioxidant, anti-inflammatory, and anti-carcinogenic properties. Two main compounds mentioned here are protocatechuic acid (PCA) and protocatechuic aldehyde (PAL).

Phenolic compounds are naturally present in many plant-based foods such as fruits, vegetables, beans, spices, rice, crops, legumes, hemp, and lentils. Herbs such as basil, lemon thyme, and mint also contain high concentrations of these anti-oxidant compounds.

Salvia miltiorrhiza, also known as red sage, Chinese sage, danshen, is a perennial plant in the genus Salvia, commonly used in traditional Chinese medicine. While Danshen possesses high concentrations of PCA and PAL, WebMD warns that eating too much of it and for some people, it can cause upset stomach. On the other hand, WebMD fails to sight any scientific evidence or research it’s claims about Danshen while acknowledging that the same therapeutic compounds in other western foods are effective (2).

According to the Handawi article, the effectiveness of distributing these antioxidants to the body and brain depends in part on the gut microbiome ability to biotransform them into lower molecular weight compounds (1).

tastes for bitter veggies influenced by oral microbes

thread

According to a November 02 2021 report by Ars Technica, oral microbiome in human saliva can affect odor detection, which may be linked to individual tastes for or against certain bitter chemicals in our food.

According to the report, about 25 percent of people can't taste propylthiouracil (PROP), a chemical that is similar to the bitter compounds found in cabbage, cauliflower, broccoli, coffee, tonic water, and dark beers. This means 75% of people detect unpleasant bitterness in these vegetables and beverages.

The bitter compounds in these foods are called glucosinolates. There are about 25 “bitterness genes”, according to scientists, which are also responsible for much of the nutritional value of these foods. Beyond the genetics, some people take kindly to certain types of bitterness and not others, matters of personal preferences.

Antibiotics are used to fight pathogens but also target commensal bacteria, disturbing the composition of gut microbiota and causing dysbiosis and disease.

According to an October 13 2021 Medical Express report, antibiotics are known to cause asthma, food allergies, obesity, gastrointestinal problems and Clostridioides difficile infections.

The October 13 2021 article in Nature said 144 antibiotics were studied to assess their affect on 38 human gut microbiome species. The study found that two common antibiotics macrolides and tetracyclines, inhibited nearly all gut bacteria tested, but also killed several species.

Gut microbiome health may affect muscle growth

thread
The researchers found that for muscles to grow following exercise, according to new a September 27, 2021 article In Medical Express written by The Physiological Society. Based on a study of mice, the gut microbiome may be important for the health of our muscles.

The study found that the mice that received antibiotic treatment which killed the bacteria of their gut microbiome showed significantly less muscle growth than mice who did not receive the antibiotic treatment.

John McCarthy, senior author added “world-class runners were found to have more of a particular type of bacteria that provided an additional source of energy which was thought to help them run faster. Thus, the gut microbiome makes substances that appear to be important for skeletal muscles,” he is quoted saying in the Medical Express report.

The microbiome of corals -- which comprise bacteria, fungi and viruses -- play an important role in the ability of corals to tolerate rising ocean temperatures, according to a September 30 2021 article in Science Daily led by Penn State University. Says Penn State biology professor Monica Medina, prolonged exposure to heat can cause 'bleaching' and the animal to die.

Viridiana Avila-Magaña, former student at Penn State, and team tracked genes that have already diverged in expression across species in response to any given stimuli -- in our case heat stress. She is currently a postdoctoral fellow at Colorado University Boulder.

The entire holobiont -- the coral animal, photosymbiont and microbiome -- is involved in the stress response. They found several genes that aid a coral’s response to heat stress. They also found more tolerant species had greater bacterial activity and diversity, according to Science Daily. The microbiome includes bacteria, fungi and viruses.

Among the three coral species examined - mountainous star coral, the knobby brain coral, and the starlet coral - the starlet coral was found to be more heat stress tolerant. This is due in part to a higher number and diversity of thermally tolerant microbes in their microbiomes, according to the Science Daily article.
