In this article, the editor compiles several research results published by scientists to tell you how important blood type is to the health of the body, and learn with you! Photo credit: medicalxpress.com.au Blood Adv: Using blood type or promising to help predict an individual's risk of contracting severe COVID-19 doi:10.1182/bloodadvances.20 In two studies published in the international journal Blood Advances before 20002623, scientists from the University of British Columbia and other institutions found that blood type may affect a person's risk of COVID-19 and the resulting serious disease.
in the first study, researchers compared more than 473,000 COVID-19 patients in Denmark with more than 2.2 million in the general population, and found that the proportion of patients with type O blood was lower in the COVID-19 patient population. , while the proportion of patients with type A, B and AB is higher, that is, individuals with type A, B and type AB blood are more likely to develop COVID-19 infection than individuals with type O blood, and the infection rate is similar among the three blood types.
in the second study, researchers included 95 patients hospitalized in Canada with severe COVID-19, and found that patients with type A and AB blood may be more likely to need mechanical ventilation to breathe, suggesting a higher risk of lung damage from COVID-19 infections.
, many patients with type A and AB blood need dialysis to treat kidney failure.
study showed that patients with type A and AB blood had a higher risk of organ abnormalities or organ failure than patients with type O and type B blood.
: Blood type, gene may affect the risk of severe COVID-19 Doi:10.1056/NEJMoa2020283 A new genetic study has found that if a person is infected with a new coronavirus, his genes and blood type may determine his risk of developing a new, more severe coronavirus.
the study, published online June 17 in the journal New England Journal of Medicine, helps to confirm earlier and more interesting evidence that blood types are associated with improved or worsening conditions.
now, a team of researchers in Europe has found that people with type A blood have a 45 percent higher risk of contracting coronavirus and developing "COVID-19 and respiratory failure" than people with other blood types.
, on the other hand, people with type O blood had a 35 percent lower risk of developing this more severe COVID-19.
humans have four main blood types: A, B, AB and O.
not clear why blood types affect susceptivity to serious diseases.
, an emergency physician at Lernox Hill Hospital in New York City, points out that genes that control blood type also play a role in the composition of cell surfaces.
changes in the surface structure of cells could affect the cell's vulnerability to new coronavirus infections, he said.
We also know from previous studies that blood types affect the risk of clotting," he said.
" medRxiv: Chinese scientists found that blood type A has a higher risk of SARS-CoV-2 infection, O blood type is the opposite doi:10.1101/2020.03. 11. The new coronavirus SARS-CoV-2 (previously known as 2019-nCoV) caused coronavirus disease (COVID-19) in 2019 and is now raging around the world.
In a new study, researchers from research institutions such as Southern University of Science and Technology, Wuhan University People's Hospital, Wuhan Jinyintan Hospital and Wuhan University Central South Hospital compared 2,173 patients with COVID-19 diagnosed with SARS-CoV-2 tests from three hospitals in Wuhan and Shenzhen, China.
data were analyzed using one-way AV and two-tailed χ2, and meta-analysis was conducted using random effect models, the results of which were recently published on preprinted server medRxiv.
1775 COVID-19 patients (including 206 deaths) came from Jinyintan Hospital in Wuhan.
113 cases and 285 COVID-19 patients were from Wuhan University People's Hospital and Shenzhen Third People's Hospital, respectively.
the main indicators were ABO blood type, SARS-CoV-2 infection rate and patient death.
ABO blood type distribution of 3,694 normal people in Wuhan was 32.16%, 24.90%, 9.10% and 33.84%, respectively, from Wuhan Gold and Silver The blood types of 1775 COVID-19 patients in Tan Hospital were: A, B, AB and O blood types were 37.75%, 26.42%, 10.03% and 25.80%, respectively.
the proportion of blood type A and blood type O increased and decreased significantly compared to normal population, respectively( P slt;0.001).
similar ABO blood type distribution patterns were observed in 398 patients from Wuhan University People's Hospital and Shenzhen Third People's Hospital.
is interesting! Whether you will be infected with noel virus or depend on the body's blood type! News read: Your blood type may influence yours to norovirus, the winter vomiting virus in the past few months, due to an outbreak of norovirus, many schools are closed, norovirus is called "stomach flu", which can cause mild diarrhea, low fever, etc. , the most worrying is vomiting symptoms, which is the most effective way to spread the virus.
Noru virus is highly contagious and can spread rapidly among a limited population in places such as schools or cruise ships, and although most patients recover within 24-48 hours, noel virus infection is the main cause of childhood disease, with about 50,000 children dying each year in developing countries from noel virus infection.
inscerely, not everyone is susceptible to norovirus, and whether an individual becomes ill may depend on the body's blood type.
When the virus is ingested by the body, it first infects cells located in the small intestine wall, and researchers aren't quite sure why the infection induces related disease manifestations, but the interesting thing is that the body's blood type largely determines whether a person gets sick.
the body's blood types include A, B, AB, and O, which are determined by gene locks, which determine the specific molecules presented by the erythrocyte table changes, namely lysosaccharies, which are formed by different Tang molecules in complex ways.
The same lysosic molecules on red blood cells also appear on the surface of small intestine cells, and viruses such as noel viruses use them to catch and infect small intestine cells, and the specific structure of these lysosic molecules determines whether a particular virus adsorptions and attacks host cells.
blood type affects our risk of heart disease or stroke? NEWS READ: A recent study by Your Blood Type Can Can Be Linked to a Higher Risk of Heart Attack or Stroke has found a relationship between blood type and heart disease and stroke risk.
specifically, if the blood type is not "O" type, the risk of developing both types of disease increases.
by analyzing the blood type of 1.3 million volunteers and their risk of heart disease and stroke, the researchers found that people with non-"O" blood types had a 9 percent higher risk of cardiovascular disease than those with "O" blood types.
but the researchers don't know if there's a causal relationship.
means that until we know enough, we can't say which blood type increases the risk of cardiovascular disease, after all, correlation doesn't represent cause and effect.
, however, is based on a large number of samples and therefore deserves further study.
our blood type is determined by the type of antigen antibody that is specific to the surface of the blood cell, and since the blood type is inherited, this has been determined before we were born.
picture source: truthinsideofyou.org: Brain Res Bull: "The brain doesn't work because of blood type!" doi:10.1016/j.brainresbull.2015.05.005 A cutting-edge study by researchers at Sheffield University found that blood types play a role in the development of the nervous system and that blood types may have a high risk of causing cognitive decline.
The study, conducted in collaboration with the IRCS San Camillo Hospital Foundation in Venice, found that people with type O blood had more gray mass in their brains than people with other blood types, such as A, B or AB, to protect them from Alzheimer's disease.
Matteo De Marco and Annana Venneri, researchers from the Department of Neuroscience at Sheffield University, analyzed MRI results from 189 healthy volunteers.
calculated the gray mass levels in the volunteers' brains and studied differences in gray mass between blood types.
study, published in the journal Brain Research Bulletin, showed that people with type O blood had more grayseed in the back of the brain.
by contrast, people with blood types A, B and AB have small amounts of gray mass in the temporal and marginal areas of the brain, including the left sea mass, one of the earliest damaged parts of the brain for Alzheimer's disease.
: Nat Med: O blood type or doi that protects the body from malaria infection: 10.1038/nm.3812 It is well known that people with type O blood are often protected from death from severe malaria In a recent paper published in the international journal Nature Medicine, scientists from The Caroline Institute in Sweden revealed the molecular mechanisms by which type O blood protects individuals from malaria death, suggesting that selective pressures caused by malaria may trigger a global distribution of human ABO blood types.
Malaria is a serious disease, with about 200 million people infected each year, including 600,000 children under 5 years of age, according to the WHO, while deadly malaria is often endemic in sub-Saharan Africa, where malaria is caused by different malaria parasite species, and the most deadly malaria parasite is Plasmodium falciparum. In plasmodium falciparum, in an individual infected with malaria, infected red blood cells are over-absorbed in the body's microcryste vessel system, blocking blood flow, causing hypoxia and tissue damage in the patient's body, which eventually leads to coma, brain damage and death.
Previously, researchers have conducted in-depth studies of the various malaria parasites that cause malaria, and researchers have long known that type O blood protects individuals against severe malaria, while other blood types do not;
: Blood type or affect your memory doi:10.1212/WNL.0000000000844 People with AB blood may be more likely to develop memory loss in later life than other blood type people.
AB is the most common blood type, accounting for about 4% of the U.S. population.
study found that people with AB blood were 82 percent more likely to develop thinking and memory problems and Alzheimer's disease than those with other blood types.
the study was a large study involving more than 30,000 people, with an average follow-up study of 3.4 years.
these people did not have memory or thinking function problems at the beginning of the study, but during the study, the study identified 495 participants with thinking and memory problems or cognitive impairments.
compared these people to 587 people without cognitive problems.
found that people with TYPE AB blood accounted for 6 percent of those with cognitive impairment, up from 4 percent of the population.
while the study looked at the relationship between blood type and cognitive impairment risk, there are studies that show that certain factors, such as high blood pressure, high cholesterol and diabetes, also increase the risk of cognitive impairment and Alzheimer's disease.
addition, blood types are also involved in other vascular diseases such as stroke, so it is important to study the link between blood types and brain health, and more research is needed to confirm these results.
.9 ATVB: Blood type affects the risk of heart disease doi:10.1161/? People with type A, B or AB blood have a higher risk of coronary heart disease than people with type O blood, according to a new study published in the journal Arteriosclerosis, Thrombosis andVascular Biology.
in the study of people with this rare blood type AB, which accounts for about 7 percent of the U.S. population, the researchers found that those with AB type had a 23 percent increased risk of heart disease.
