Columbia researchers develop kidney disease-spotting algorithm

Photo by Steve Dabenport/Getty Images Researchers at Columbia University Vagelos College of Physicians and Surgeons have developed an algorithm that automatically scours electronic health records to alert physicians to early-stage chronic kidney disease.   The algorithm searches EHRs for results of blood and urine tests before performing calculations to indicate kidney function and damage and alerting clinicians. Identifying kidney disease early is of paramount importance, because we have treatments that can slow disease progression before the damage becomes irreversible, said study leader Dr. Krzysztof Kiryluk, associate professor of medicine, in a statement to press.   WHY IT MATTERS   More than one in seven adults is estimated to have chronic kidney disease, according to the U.S. Centers for Disease Control and Prevention, but as many as 90% don t know they have it.  

Vadadustat Matches Standard for CKD-Related Anemia, With Caveat

email article The investigational hypoxia-inducible factor (HIF) prolyl hydroxylase inhibitor vadadustat was noninferior to the erythropoiesis-stimulating agent darbepoetin alfa for treating anemia in chronic kidney disease (CKD) patients, a pair of phase III trials found. 2TECT Study of non-dialysis-dependent CKD treatment with vadadustat met the pre-specified noninferiority endpoint for hematologic efficacy compared with darbepoetin alfa, reported Glenn Chertow, MD, MPH, of Stanford University School of Medicine in California, and colleagues. Looking only at ESA-untreated patients, there was an average between-group hemoglobin concentration difference of 0.05 g/dL (95% CI -0.04 to 0.15) maintained from weeks 24 to 36 with vadadustat or darbepoetin alfa treatment.

COVID-19 survivors face higher risk of death and serious illness

COVID-19 survivors including those not sick enough to be hospitalized have an increased risk of death in the six months following diagnosis with the virus, researchers report. As the COVID-19 pandemic has progressed, it has become clear that many survivors even those who had mild cases continue to manage a variety of health problems long after the initial infection should have resolved. The researchers have catalogued the numerous diseases associated with COVID-19, providing a big-picture overview of the long-term complications of COVID-19 and revealing the massive burden this disease is likely to place on the world’s population in the coming years.
