New blood test can detect 8 types of cancer
The advances in science for the identification of tumors increasingly early has evolved enough. Recently, researchers at Johns Hopkins University in the United States have created a new blood test that can identify eight types of cancer before the disease evolves and spreads to other organs.
The test, called CancerSEEK, will have the estimated cost of $ 500 (something around $ 1,600 today - figure searched on 1/23/2018), say the researchers in the article published in the American scientific journal Science.
The research was done with 1,005 volunteers who had symptoms who already had a pre-diagnosis of cancer, and who were diagnosed with a blood test with an accuracy rate of about 70% in total. The cancers found by the examination were: ovarian cancer, liver cancer, stomach cancer, pancreatic cancer, esophageal cancer, colon cancer, lung cancer and breast cancer.
Some types of cancers, such as ovarian, liver, stomach, pancreas and esophagus, there are no screening exams available for persons at medium risk, however, CancerSEEK was able to identify these five types, with a sensitivity rate of 69% to 98%. , including the anatomical location of cancer in 83% of cases. The non-invasive test is based on a combined analysis of DNA mutations in 16 cancer genes and at the levels of 10 circulating protein biomarkers. Although promising, scientists point out that further testing and enhancement of the technology is still needed before it reaches the market.
A stressful day after a bad night's sleep can be a particularly harmful combination of blood pressure, a new study by scientists at the University of Pittsburgh in the United States shows. Earlier studies have shown that lack of sleep can affect blood pressure, leaving people more prone to cardiovascular problems such as high blood pressure, stroke and stroke.
Since suspected cases of yellow fever have become common in several regions of Brazil, the demand for the yellow fever vaccine has increased. As a strategy to meet more people with this immunization, the Ministry of Health decided to implant the fractional dose of the vaccine in some municipalities of São Paulo, Rio de Janeiro and Bahia.
