Machine learning illuminates genetic links between blood cells and disease

Machine learning illuminates genetic links between blood cells and disease

Credit: CC0 Public Domain Scientists from the Cambridge Baker Systems Genomics Initiative have used machine learning to create genetic predictors of blood cell traits, such as white blood cell counts, that are linked to chronic disease. The research, published today in the journal Cell Genomics, identified shared genetic architecture between blood cell traits and various …

Long-term use of blood pressure medication could be contributing to kidney damage

Long-term use of blood pressure medication could be contributing to kidney damage

New kidney research from the University of Virginia School of Medicine is raising concerns that long-term use of drugs commonly prescribed to treat high-blood pressure and heart failure could be contributing to kidney damage. Patients should continue taking the medications, which include the well-known and widely used ACE inhibitors, the researchers say. But the scientists …

New graft strategy may improve outcomes for blood stem cell recipients

New graft strategy may improve outcomes for blood stem cell recipients

Credit: CC0 Public Domain Removing one type of T cell from donor blood used for stem cell grafts could greatly reduce a serious complication called graft-versus-host disease in patients with leukemia, according to a new study. Published today in the Journal of Clinical Oncology, the study reports that only 7% of leukemia patients who received …

Blood test helps predict who may benefit from lung cancer screening

Credit: CC0 Public Domain A blood test, combined with a risk model based on an individual’s history, more accurately determines who is likely to benefit from lung cancer screening than the current U.S. recommendation, according to a study published today in the Journal of Clinical Oncology led by researchers from The University of Texas MD …

Blood test may one day predict severe pregnancy complication

Credit: Unsplash/CC0 Public Domain A blood test may one day be able to predict whether someone who is pregnant will develop a serious blood pressure disorder months before symptoms show up. Preeclampsia happens in around 1 of 20 pregnancies, usually in the third trimester, and can cause organ damage, stroke and preterm birth. Pregnancy-related high …

Changes in the blood, not the heart, may underlie cardiac thrombosis in COVID-19 patients

A: The number of neutrophil-platelet aggregates per 20x field was quantified in patients and controls. B and C: Patient tissue images of neutrophil-platelet aggregates and a neutrophil during NETosis, capturing platelets. D: Neutrophil rich macrothrombi composed of more than 30% neutrophils were counted in entire tissue at 10x. Values were normalized by tissue area. E …
