Another reason to cook meat and pay attention around the cat litter box is:Parasite Toxoplasma gondiiNew studies suggest that breeding in cats and most often spreading to humans through raw meat may increase the risk of human brain tumors.
Researchers T. Gondy antibody The most common type of people’s blood, showing previous exposure to parasites, and the development of glioma Brain tumor,A few years later.
Survey results published on Monday (January 11) International Journal of Cancer, “Individuals with higher exposure T. Gondy Parasites are more likely to develop gliomas, “said Anna Coghill, a research co-author and cancer epidemiologist at the Mofit Cancer Center in Tampa, Florida. Said in a statement.. However, Coghill warns that current findings “need to be reproduced in larger, more diverse groups of individuals,” and the overall risk of developing glioma in a lifetime is low. It remains.
Moreover, current studies cannot prove a causal relationship. “This does not mean that T. Gondy “Some people with glioma do not have glioma,” James Hodge, an epidemiologist and research co-author of the American Cancer Society in Atlanta, said in a statement. T. Gondy Antibodies and vice versa. ”
Relation: Seven Strange Facts About the “Mind Control” Parasite Toxoplasma Protozoan
Brain parasite
T. Gondy It infects most warm-blooded animals, including humans. However, because sexual replication occurs only in cats, they must be infected and complete their life cycle. Parasites that can infect the brain Reduced alertness to cats for infected rodents And promotes its own replication. It is also related to human risky behavior. Humans can be exposed to parasites by scooping cat toilets from infected pets, but a more common route of exposure is to ingest raw or undercooked meat from infected animals.
T. Gondy Infectious disease known as ToxoplasmosisIs common, affecting an estimated 2 billion people worldwide and 40 million in the United States. Live Science previously reported.. Most people with infections have no symptoms because the immune system suppresses the parasites, but in rare cases, the parasites can cause serious symptoms such as loss of vision. Centers for Disease Control and Prevention (CDC)..
Glioblastoma is a deadly cancer, and glioblastoma is its most deadly subtype. The estimated 5-year survival rate for glioblastoma is only 6% in people 55 years and older compared to the general population without cancer. American Cancer Society.. Risk factors for glioma include men, non-Hispanic Caucasians, the elderly, and tall.
To investigate the effect of T. Gondy Researchers at risk of developing glioma T. Gondy In blood samples from people with glioma (samples were collected years before diagnosis) and cancer-free controls. Researchers used blood samples and data from participants in two early studies, the American Cancer Society Cancer Prevention Study-II Nutrition Cohort (CPSII-NC) and the Norwegian Cancer Register Janus Serum Bank (Yanus). did.
Participants with glioma were more likely to have antibodies than participants in the control group T. Gondy In their blood samples, the researchers found.In addition, in participants of the Janus study, the risk of glioblastoma is T. Gondy Researchers have found that the higher the antibody level, or antibody level, the higher the risk. However, T. Gondy Exposure and risk of glioma were statistically meaningless for all individual antibodies tested and all glioma subtypes.
This was the first prospective study — that is, the study we investigated. T. Gondy Report the relationship between pre-cancer exposure- T. Gondy Exposure and development of glioma, the authors wrote. This study design allowed researchers to avoid the possibility that the link between gliomas and parasites is actually due to gliomas, increasing the risk of infection by the parasites.
Identification T. Gondy It may have practical implications as a risk factor for glioma. Most risk factors for glioma are not correctable, but exposure to parasites is something that people can try to avoid, the authors say.
If other studies confirm these findings, “reducing exposure to this common food-borne pathogen provides the first concrete opportunity to prevent this highly aggressive brain tumor. Would, “they conclude.
Jeff Hyde, a parasitologist at the University of Salford in the United Kingdom, said, “In principle, T. Gondy Exposure may prevent some gliomas — probably because there is less stress on the immune system. Hide wasn’t involved in the current study, but he co-authored the 2019 study in the journal. ERJ Open Research Report links between the existence of T. Gondy Antibodies and lung cancer.
“This study suggests a link between exposure and exposure. Toxoplasma gondii Dr. Craig Hobinski, a neuropathologist at the Fineberg School of Medicine at Northwestern University in Chicago, told Live Science by email. cancer. “
However, both Horbinski, who was not involved in the study, and the authors of the study believe that more data is needed to determine if a link between parasite exposure and the development of glioma applies. I am. “The data are interesting, but not enough to draw solid conclusions,” Hobinski said.
In the future, researchers should do more research on larger populations, including more cases of glioma, Horbinski said. “That’s the only way to resolve this dispute,” he added.
