Though promoted for treating various medical conditions, evidence of its benefits was mixed as of 2020 , showing effectiveness in certain conditions ...

The abnormal protein PrP Sc accumulates in the brain and destroys nerve cells, which leads to the mental and behavioral features of prion diseases.

There is no risk of receiving the wrong red cells. [27] The devices used are very similar to the devices used for therapeutic plasmapheresis, and the potential for citrate toxicity is similar. The potential risks are explained to prospective donors at the first donation, and most donors tolerate the procedure well. [28]
It is administered by slow injection into a vein. [2] Side effects include nausea and itchiness. [3] Rarely there may be allergic reactions, blood clots, or infections. [1] [3] It is unclear if use during pregnancy or breastfeeding is safe for the baby. [2] Greater care should be taken in people with protein S deficiency, IgA deficiency, or ...
Smokers, people with diabetes, individuals with muscle atrophy or fatty infiltration, and those who do not follow postoperative-care recommendations also are at greater risk. In a 2008 study the frequency of such tears increased from 13% in the youngest group (aged 50–59 y) to 20% (aged 60–69 y), 31% (aged 70–79 y), and 51% in the oldest ...
