(Press-News.org) Houston, TX (November 8, 2025) — It can be challenging to identify which patients with advanced chronic kidney disease (CKD) will most benefit from conservative care rather than initiating dialysis. Researchers recently developed and validated a prediction model to estimate individualized survival probabilities with conservative non-dialytic management versus dialysis in patients with advanced CKD from the national Veterans Affairs and OptumLabs® DataWarehouse databases. The work will be presented at ASN Kidney Week 2025 November 5–9.
Investigators found that among veterans with advanced CKD who received dialyticversus non-dialytic management, certain factors were linked to higher mortality risk, including older age; higher baseline and more rapid decline in estimated glomerular filtration rate; higher albuminuria levels; worse frailty indices; lower serum albumin and lower body mass index; recent hospitalization; underlying heart disease, sepsis, or tobacco use; and dialysis transition.
“This new risk prediction tool was developed to estimate the individualized probability of survival with conservative non-dialytic management versus dialysis transition, which demonstrated moderate discrimination (the ability to accurately differentiate between those at higher versus lower risk) and acceptable calibration performance (the degree of agreement between the predicted mortality risk probability and the actual observed probability of death) in two national cohorts of patients with advanced CKD,” said corresponding author Connie Rhee, MD, MSc,of the University of California Los Angeles and the Veterans Affairs Greater Los Angeles Healthcare System. “This study was conducted as part of the NIH-funded ‘Defining Optimal Transitions of Care in Advanced Kidney Disease: Conservative Management vs. Dialysis Approaches (OPTIMAL)’ study, in which our objective is to establish a stronger evidence base for conservative non- dialytic management in the advanced CKD population. By rigorously studying the comparative effectiveness of conservative management versus dialysis transition, findings from our and others’ research have thepotential to expand viable, patient-centric treatment options for CKD. We aim for this tool and other approaches to support and enhance the shared decision-making process regarding conservative management versus dialysis initiation among patients, care partners, and health care providers.”

In a new study of more than 40,000 patients, researchers at Intermountain Health in Salt Lake City have found that patients who have no evidence of calcium in their coronary arteries are not only significantly less likely to die from heart conditions – including heart attacks and heart failure– but also are at reduced risk of death from non-cardiac medical conditions.
Coronary artery calcium (CAC) is a strong predictor of how likely someone is to develop clinical coronary artery disease. It is an excellent measure of coronary plaque burden.
When cholesterol-laden plaque builds up in the coronary arteries, blood flow to heart muscle is limited, and plaque rupture with coronary ...
Coronary artery calcium (CAC) CT scans are becoming a more commonly used tool to effectively determine a patient’s future risk of heart disease and heart attack.
These minimally invasive scans measure how much calcium is already present in the arteries of the heart, so that clinicians can determine if a patient needs medical intervention or other preventative measures, including statin medications.
Now an important new study from heart researchers at Intermountain Health in Salt Lake City ...
Sodium-glucose co-transporter 2 (SGLT2) inhibitors reduce albuminuria (excess albumin in the urine) and the risk of chronic kidney disease (CKD) progression, and certain mineralocorticoid receptor antagonists have similar effects in people with type 2 diabetes and CKD. Investigators recently assessed the albuminuria-lowering efficacy and safety of the novel mineralocorticoid receptor antagonist balcinrenone combined with the SGLT2 dapagliflozin. In the double-blind, active-controlled clinical trial, both doses of this novel balcinrenone/dapagliflozin combination outperformed dapagliflozin alone, cutting levels of ...
Researchers from Mass General Brigham have unveiled the results of a large clinical trial that found that adding the drug evolocumab to patients’ treatment significantly reduced the risk of major adverse cardiovascular events in those who are at high risk. Results were presented today at the American Heart Association Scientific Sessions and simultaneously published in The New England Journal of Medicine.
“The results of this trial offer hope for preventing a first heart attack, stroke, or other ...
Researchers from Mass General Brigham have found that olezarsen—a drug designed to lower triglyceride levels—can also decrease the risk of acute pancreatitis, a potential complication in patients with severely elevated triglyceride levels. The results, from two randomized, placebo-controlled trials (CORE-TIMI 72a and CORE2-TIMI 72b), were presented at the American Heart Association Scientific Sessions and simultaneously published in The New England Journal of Medicine.
Severe hypertriglyceridemia is a condition in which the level of triglycerides (a type of fat that circulates in the blood) is very high. Approximately 1 in 100 people in the U.S. have severe hypertriglyceridemia. ...
Steatotic liver disease (SLD), mainly encompassing metabolic dysfunction-associated steatotic liver disease (MASLD), alcohol-related liver disease (ALD), and metabolic dysfunction and ALD (MetALD), has emerged as the dominant cause of chronic liver disease worldwide, displacing viral hepatitis as the primary aetiology. Globally, the prevalence of MASLD is estimated even over 30%, affecting over one-third of adults. Parallelly, alcohol remains a major risk factor, with heavy drinking contributing to 90–95% of SLD cases and up to 10% advancing to cancer.

In late-breaking presentations at the American Society of Nephrology Kidney Week meeting and simultaneously published in two companion papers in JAMA, the findings are based on data from over 70,000 participants across 10 major randomised controlled trials. The meta-analyses were conducted by the SGLT2 Inhibitor Meta-analysis Cardio-Renal Trialists’ Consortium (SMART-C), led by The George Institute for Global Health.
SGLT2 inhibitors, originally developed to treat type 2 diabetes, have since demonstrated substantial protection against heart failure and chronic ...
Despite effective HIV medication, the immune system of people with HIV remains disrupted in the long term. Researchers at Amsterdam UMC investigated whether this dysregulation can be prevented by starting HIV medication immediately after infection – i.e. within a few days. They saw that six months after this early treatment, the immune system did indeed work as in people without HIV. But in the longer term, the immune system was disrupted again. This is shown by research by Amsterdam UMC, published in the journal EBioMedicine.
Early treatment protects immune systems only temporarily
For this study, the scientists examined ...
Record numbers of men and women globally are now estimated to have reduced kidney function, a new study shows. Figures rose from 378 million people with the disease in 1990 to 788 million in 2023 as the world population grew and aged, making it for the first time a top 10 cause of death worldwide.
Led by researchers at NYU Langone Health, the University of Glasgow, and the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, the analysis explored the rise of the illness, in which the kidneys gradually lose their ability to filter waste and excess fluid from the blood. Mild cases may have no symptoms while the most severe stages ...
