Are donor traits transmitted to recipients through blood transfusions?!

There is no doubt that blood transfusions are life-saving, but some transfusion recipients report changes in mood, behavior, and even their memories after undergoing the procedure.
The potential effects of blood transfusions were recently revealed in a new study that linked spontaneous brain bleeding to this procedure in rare cases.

According to the study conducted by researchers from the Karolinska Institute in Sweden, the University of Copenhagen in Denmark and other institutions, patients who received blood from donors who suffered from brain bleeding were themselves more likely to suffer from bleeding as well.

There are concerns that cerebral amyloid angiopathy, also known as congenital angiopathy, which causes a buildup of proteins in blood vessels in the brain, could spread through blood transfusions, thus causing bleeding.

If this phenomenon is confirmed, researchers say more research is needed.

Last month, researchers at the Karolinska Institutet in Sweden published a large study suggesting that, for example, the cause of a spontaneous brain hemorrhage can be transmitted from donor to recipient via blood transfusion.

The study, published in the Journal of the American Medical Association, found that patients who received blood from donors who had previously had recurrent brain bleeds were more than twice as likely to suffer the bleed themselves.

The researchers relied on a Swedish-Danish database containing information on donors and patients receiving blood transfusions from the 1970s onwards, and more than one million patients were included.

The findings suggest that some of the factors that can lead to spontaneous brain hemorrhage can be spread by blood transfusion. However, since only 0.1% of donors in the study had previously experienced recurrent brain bleeding, this affected a small number of patients.

“Blood transfusions are relatively common, making adverse effects an important public health issue,” said Gustav Edgren, associate professor of epidemiology and one of the researchers on the recent study. “However, you are unlikely to suffer a brain bleed from something transmitted through a blood transfusion.” ".

The researchers now plan to examine samples from the Biobank Study of Danish blood donors to see if they can identify abnormal proteins associated with the condition, which may damage blood vessels.


Doctor explains the results of "neck cracking"

Some people try to crack their neck to relieve tension caused by poor posture, but they do not know what damage this process can cause.
Dr. Andrei Kapichkin, a specialist in spinal diseases and reflexology, explains in an interview with Sputnik Radio what this operation can lead to.

A common habit we practice that may lead to serious consequences!
According to him, poor posture while walking or a sedentary lifestyle can lead to tension in the cervical vertebrae which can be removed by cracking the neck, but this process is unsafe for health.

He says: “There are spacers between adjacent vertebrae in the neck. For example, when the capsules of these spacers are compressed due to incorrect posture, pain appears resulting from spondyloarthritis - which is destructive degenerative changes in the spacers of the spine. The occurrence of cracking indicates the release of the spacer capsule, after which the vertebrae begin "By moving naturally, the muscles relax, and this can bring relief. However, it is not recommended to do this on your own without the help of a specialist doctor, because the person could put pressure on the vertebral artery."

The specialist goes on to explain that if the neck “cracking” operation is not successful, a disturbance in the blood supply to the cerebellum may occur.

He says: “The vertebral artery passes through a fine bone canal and supplies blood to the cerebellum. The cerebellum is responsible for the stability of our gait and the correct body position. Therefore, if this artery is damaged, the cerebellum will suffer from a lack of oxygen, which leads to the person feeling dizzy, and this condition is called “vertebrobasilar insufficiency.” “. Any circulatory disorder resulting from mechanical damage. Of course, this is not a stroke. However, if symptoms of this disorder appear, you must consult a doctor and undergo treatment.”
