Observation may become a promising new method of diagnosing diseases.
Scientists at Washington University in St. Louis have found that bacteria in the gut can predict Alzheimer’s disease. The results of the work were published in the journal Science Translational Medicine.
Previous studies have shown that certain clusters of microorganisms occur in the gut of people with early signs of various diseases, at stages when it is still difficult to determine them. This observation may become a new promising method for diagnosing diseases.
Now experts have noticed that some types of bacteria can be found in the preclinical stage of dementia. In particular, Faecalibacterium prausnitzii (F. prausnitzii) is more common in the gut microbiome of people without dementia.
However, the authors also noticed the presence of other microorganisms in the body of those who began to develop Alzheimer’s disease, although these bacteria were previously considered beneficial to health.
It has not yet been possible to explain this relationship, however, it is possible that the whole thing is in the stage of the disease. So, not everyone who has signs of preclinical Alzheimer’s disease will develop Alzheimer’s disease itself in the future.
There may be changes in the gut microbiome (decrease in F. prausnitzii) that are characteristic of later stages of the disease.
In June 2023, a research team from around the world, including researchers from the University of Wisconsin-Madison (USA), proved that gut bacteria can help control plaque buildup in the arteries, preventing cardiovascular disease.
Modern medicine does not stand still and is constantly evolving. Read in the gallery regarding the main medical discoveries of the XXI century:
Two of the three types of polio have been eradicated; the last one is coming. Following the type 2 poliovirus, officially declared eradicated in 2015, type 3 virus ceased to exist on October 24, 2019. The last case of infection was recorded in 2012 in Nigeria. All of this has been made possible by the widespread use of vaccines since the 1950s.

Artificial intelligence has learned to predict the structure of proteins. The ability to predict, simply from the sequence of amino acids, what the three-dimensional structure of any protein, of which there are hundreds of thousands in the human body, will not only revolutionize biology, it opens up new possibilities for drug development and the treatment of many diseases.

Malaria will be defeated. Malaria might be completely eradicated by 2050, according to The Lancet. As one of the decisive measures, it is proposed to change the DNA of mosquitoes, which will lead to their infertility or make them resistant to malarial plasmodia.

CRISPR/Cas9 is a genome editing technology that allows it to be adapted for treatment. Theoretically, it will make it possible to better study the course of various complex diseases and “reprogram” the diseased organism for recovery.

Creation of antibodies for viral diseases. Laboratory-created monoclonal antibodies have already revolutionized the treatment of autoimmune diseases and certain types of cancer, but so far their use for treating infections has been limited.

HIV and AIDS are on the decline. The effectiveness of modern ARV therapy has already been proven, and in recent years several patients from different countries have been completely freed from the diagnosis.

First coronavirus vaccines in record time. The way humanity reacted to the coronavirus pandemic, of course, cannot be called a standard – but thanks to the active work of the scientific community, it was possible to create effective vaccines very quickly.

Cancer has been identified through a blood test. In 2020, trials of a universal blood test started in the UK, which allows to detect up to 50 types of cancer at an early stage. The study will be completed in 2023, and if it shows its effectiveness, then by the middle of the decade, blood tests for cancer will become massive.

Hepatitis C has become completely curable. Literally over the past few years, the effectiveness of drugs from the “gentle killer” has approached 100%. Such progress came with the introduction of interferon-free treatment regimens.

Alzheimer’s disease will learn to predict. Alzheimer’s blood test is another small medical revolution of 2020. Scientists have learned to identify the relevant biomarkers in blood plasma regarding four years before the onset of the first symptoms of the disease, which means that such a blood test can be included in annual medical examination programs and recommendations for patients.
