Gut may be involved in Covid 19

1月

There is mounting evidence suggesting that our gut microbiome is involved in the Covid 19 disease, according to a January 04 2021 report released publicly in the BMJ's (British Medical Association journal) Gut, based on research by the Chinese University of Hong Kong.

The study samples and records of 100 patients infected with SARS-CoV-2. The study found that the microbiome composition was significantly altered in patients with COVID-19 compared with non-COVID-19 individuals, according to BMJ. Researchers found that covid 19 patients had a significant deficiency of Faecalibacterium prausnitzii, Eubacterium rectale and bifidobacteria. These gut bacteria species are known to keep our gut health in balance. Its deficiency results in dybiosis.

Moreover, these patients also experienced unusually high concentrations of cytokines and other inflammatory markers accepted by the medical community. Covid patients continue to experience dysbiosis long after their recovery.

Bacteria and milk in Kefir depend on each other for survival

After studying 15 kefir samples, the researchers discovered to their surprise that the dominant species of Lactobacillus bacteria found in kefir grains cannot survive on their own in milk -- the other key ingredient in kefir. However, when the species work together, feeding on each other's metabolites in the kefir culture, they each provide something another needs.

Another break gut microbiome and health, a study of the bacteria Sphingomonas desiccabilis by Dr. Charles S. Cockell, a professor of astrobiology at the University of Edinburgh, was able to separate rare earth elements from rock, according to a November 11 2020 New York Times article by Kenneth Chang. In the test, Cockell and his associates with help from the European Space Agency, used S. desiccabilis to increase the amount of rare earth elements extracted from the basalt by roughly a factor of two.

The team tested this at the space station, where Luca Parmitano, a European Space Agency astronaut, placed some of the S. desiccabilis in a centrifuge spun at speeds to simulate Mars or Earth gravity, and in zero-gravity environment.

Gut microbiome connection to sleep

Medical News Today reported December 24 2020 new research from Japan's University of Tsukuba that gut bacteria helps create important chemical brain messengers such as serotonin and dopamine, positively impacting one's sleep patterns.

"We found that microbe depletion eliminated serotonin in the gut", according to Prof. Masashi Yanagisawa quoted in the Medical News Today article.

Avacados: good for you; good for your gut

We already know that avacados are good for us. A large part of the reason is avacados are high in monounsaturated heart healthy fiber.

A study by the University of Illinois Division of Nutritional Sciences was conducted on 163 young adults who ate avocado every day, according to a December 14 2020 article in Neuroscience News. Researchers found a greater abundance and diversity of gut microbes that break down fiber, reduced bile acids, and increased short chain fatty acids among the test subjects, according to Sharon Thompson, graduate student of the University of Illinois nutritional science program.

The study was led and co-authored by Dr. Hannah Holscher, assistant professor of nutrition in the Department of Food Science and Human Nutrition.

New sequencing technology tests for microbes on historic art and relics

12月

Thanks to nanopore technology, we can trace microbes from years past. A new “nanopore” genetic sequencing device from Oxford Nanopore Technologies uses fewer reagents and chemicals to process the samples than do previous generations of sequencing technology, according to a Wired magazine article quoting Guadalupe Piñar, a microbiologist at the University of Natural Resources and Life Sciences in Vienna.

The sequencer is sensitive enough to take what little DNA the researchers can dab off of drawings without damaging valuable articles and relics, and identify an array of microbes.

several studies link dysbiosis of our gut microbiome to depression

Yet another study has linked depression to disruptions in our gut microbiome, according to a December 03 2020 article by Medical Express. Several institutions in China and two in the U.S. researched the matter originally published in the journal Science Advances. Previously, major depressive disorder (MDD) studies have found the gut microbiome species Coprococcus and Dialister were depleted in patients with depression (1), whereas butyrate-producing Faecalibacterium and Coprococcus bacteria are linked to higher quality of life.

Specifically, this team of researchers studied fecal samples from 156 MDD patients, individuals with MDD. They found 47 bacterial species, 50 fecal metabolites, and three bacteriophages that were different from their control group of 155 non-MDD or healthy individuals (2). The differing, depleted gut bacteria species in MDD patients include 10 species from the bacteriods family, 29 from blautia, 5 from eubacterium, 3 from clostridium, according to the Science Advances report (3).

A study by the University of Turku announced by Science Daily on November 20 2020, determined that 54% of the human gut bacterial species have some sensitivity to glyphosate, the most commonly used herbicide. The results are based on a bioinformatics tool developed by Docent Marjo Helander at the University of Turku.

Helander plans to further research the A rich and diverse microbial community is living in soil, on plant surfaces, and in animal guts. It is possible that even low glyphosate residue may indirectly affect pest and pathogen occurrence in these communities.

Vitamin D - gut microbiome connection

12月

17日

Researchers at the University of California San Diego were able to demonstrate that the makeup of a person's gut microbiome is connected to their levels of active vitamin D, according to a November 30 2020 Medical Express article.

It is believed and confirmed by numerous studies that vitamin D has important health benefits such as lowering risk of cancer, heart disease. A clinical study of more than 25,000 adults found that found that vitamin D supplements has no health benefits at all as originally believed.

Said author Deborah Kado, MD, director of the Osteoporosis Clinic at UC San Diego Health as quoted in the Medical Express, "it doesn't matter how much vitamin D you get through sunlight or supplementation, nor how much your body can store; it matters how well your body is able to metabolize that into active vitamin D." This points to the conclusion that bacteria plays a role in metabolizing vitamin D, adds Kado.

According to a December 01 2020 article published by the Massive Science Consortium, scientists at the University College, Cork measured the effects of different antidepressants on common gut bacteria on petri dishes.

Scientists found that antidepressants inhibited the growth of gut bacteria. The study found that desipramine and aripiprazole were particularly detrimental to our gut bacteria. This research points to opportunity to reduce negative side effects of antidepressants.
