Researchers from Johns Hopkins University Bloomberg School of Public Health, US, developed a new non-fasting blood test that can help identify youth at risk of developing type 2 diabetes and prediabetes.
The results of the conducted study suggest that this simple blood test, hemoglobin A1c (HbA1c), should be used more often to screen young people for diabetes and health risks connected with this condition. The HbA1c test is accurate and easy to administer in young patients.
Study authors write in their paper: “Our study demonstrates that HbA1c is a useful non-fasting test for identifying high-risk youth who could benefit from lifestyle interventions to prevent diabetes and cardiovascular disease later in life.”
According to recent research, some readings from a routine blood test, used as markers of immune condition and inflammation, may indicate people that are at higher risk of disease and death associated with this disease.
For the study, the researchers analyzed data from 31,178 participants that were collected from them within the National Health and Nutrition Examination Survey (NHANES). The analysis results showed that people with low levels of lymphocytes had a higher risk to die from heart disease, cancer, and respiratory conditions.
Study author Jarrod E. Dalton, Ph.D., an epidemiologist at the Cleveland Clinic’s Lerner Research Institute, says: “The complete blood count test is convenient, inexpensive, and — as our findings suggest —may be used to help physicians screen for and prevent disease and disease-related mortality.”
Last year a team of researchers from Rensselaer Polytechnic Institute, US, developed a simple blood test for diagnosing ASD (autism spectrum disorder). At the present moment, a follow-up study confirms the original finding.
In this test, there is an algorithm that takes into account the presence and concentration of numerous chemicals in the blood associated with ASD.
To make the test more predictive, the scientists worked with children divided into several groups within the existing studies. Using the test, they found 154 aged from 2 5o 17 years.
Systems biologist and senior author Juergen Hahn says: “This is an approach that we would like to see move forward into clinical trials and ultimately into a commercially available test.” She also adds: “We were able to predict with 88% accuracy whether children have autism.”
A team of scientists from Johns Hopkins University School of Medicine created a new blood test that can be a much simpler and more effective diagnostic technique than most of the modern techniques. This technique called CancerSEEK and has the potential of identifying 8 types of cancer from one sample of blood.
For the study, the researchers tested CancersEEK on 1,005 individuals who were diagnosed with non-metastatic forms of one of the 8 cancers. They discovered that the test was able to identify 70% of cancers. Its sensitivity varied depending on the cancer type.
Study co-author Dr. Bert Vogelstein of Johns Hopkins University School of Medicine says: “This test represents the next step in changing the focus of cancer research from late-stage disease to early disease, which I believe will be critical to reducing cancer deaths in the long-term.”
Researchers from the US developed a method for diagnosing schizophrenia. A report about their work can be found in the journal Analytical Chemistry.
Scientists offer diagnosising chizophrenia to pay attention to oxidative stress – cell damage due to oxidation.
In their view, this mechanism is closely associated with many diseases, including schizophrenia and other mental disorders.
The new approach has been tested on a cohort of patients with schizophrenia and healthy individuals. As a result, researchers were able to correctly separate the blood samples of sick people from healthy one. For the detection of oxidative stress they used iridium salt as for the evaluation of the process in the food products.
The researchers hope that their technique will be used for the diagnosis of schizophrenia: the sooner the disease is found, the more successful it is treated. Now the diagnosis is sometimes stretched for a year.
