Brush your teeth well! Oral bacteria found in brain of stroke patients

Oral health is an important part of overall healthIn recent years, many studies have reflected the association between periodontal disease and cardiovascular diseaseIt is generally believed that this may be due to the inflammation caused by the infection with a systemic effectHowever, there have also been studies suggesting that the mechanisms behind it may be more complexrecently, a team from Tampere University in Finland found signs of common oral bacteria in blood clots in the brains of stroke patients! This means that, in addition to inflammation, bacteria may also be involved in the formation of blood clotsThe study was also published in journal of the American Heart Association, the official journal of the American Heart Associationthe team has been studying the link between bacterial infections and cardiovascular disease for more than a decadePreviously, they had found the DNA of the oral bacteria, the ahemolytic streptococcus A, in thrombosis samples of the heart attackOther studies have found that brain aneurysms and leg blood clots have the same bacterial tracesthe bacteria are known to cause infectious endocarditis and are associated with thrombosisBut in the case of arterial thrombosis in the brain, it remains to be seen whether oral bacteria play a roleWith the development of brain blood reconstruction techniques such as stent implantation and pumping hydrants, researchers now have the opportunity to study cerebral thrombosisthe new study included 75 patients with ischemic stroke (stroke) treated with mechanical hydrants at the University Hospital of Tampere, Finland, between 2013 and 2017, to measure bacteria in blood clots that were pumped outresearchers detected bacterial DNA in 84% (63 people) of thrombosis samples, the vast majority of which (59) contained streptococcus DNA common lying in the mouthEven more striking is that the average content of all bacterial DNA in blood clots is almost eight times that of these patients' own blood samples, and the average level of streptococcus DNA in blood clots is more than five times that of controlled blood samplesDrOlli Patrakka, lead author of the study, said it was "the first study to show the prevalence of this bacterial infection in patients with ischemic stroke, and oral bacteria may have played a role in the serious complications associated with atherosclerosis, such as thrombosis." speculation about oral health and cardiovascular disease, the American Heart Association convened a panel of experts in 2012 to discuss Scientific statements at the time showed that there was insufficient evidence that bacterial gum disease was the cause of heart disease, or that treating gum disease could help prevent heart disease Although the new study does reveal traces of bacteria in the brain, industry experts are cautious Professor Peter B Lockhart of the Department of Oral Medicine at the Carolina Medical Center, who participated in the scientific statement in 2012, said it is not uncommon for oral bacteria to enter the bloodstream, regardless of whether an individual is healthy or has periodontal disease Once, blood was considered sterile, "but now we already know that bacteria exist throughout the body, including in the blood, and finding traces of bacteria in blood clots doesn't necessarily mean they work in the course of the disease." However, the team believes that "future research will reinforce this view that oral care has more important health effects than previously thought." Dr Patrakka also said regular dental check-ups may help reduce the risk of heart disease Reference s Olli Patrakka, et al., (2019) Oral Sed Sin Tony in Cerebral Thrombi of Patients With Acute Ischemic Stroke Treated With Thrombecttomy Journal of the American Heart Association, 10.1161/JAHA.119.012330 What dos it mean?
