Salt and blood sugar links offer new clues for kidney care.
Today's news focuses on observational studies that show links between diet, blood sugar, and kidney health. These findings help doctors identify risks but do not prove direct causes. A new trial is also starting to test how best to lower blood pressure in kidney patients.
Wound healing, limb salvage and mortality after limb-salvage treatment in patients with diabetes and end-stage renal disease with limb-threatening ischemia: a systematic review and single-arm meta-analysis
This preprint is a meta-analysis that pools data from many studies on wound healing in people with diabetes and end-stage kidney disease. It looks at how well wounds heal after limb-salvage treatment. It is a preprint, so it has not been peer-reviewed yet. It provides a broad view of outcomes for this high-risk group.
Applications of artificial intelligence in chronic kidney disease: a systematic review.
This review looked at how computer tools help find and manage kidney disease. It checked studies from 2019 to 2025. The review shows these tools can spot problems early. It is a summary of many studies, so it is strong evidence.
Diagnostic accuracy of AI-augmented renal ultrasound for degenerative kidney disorders: a systematic review and meta-analysis.
This review looked at 18 studies and found AI added to kidney ultrasound correctly identified degenerative kidney disease in most cases — about 85% accurate for detecting scarring and 78% accurate for staging disease severity. The AI tools were tested on images from real patients, but no study yet shows this improves patient outcomes. A large randomized trial is needed to prove it helps people keep their kidneys longer.
Influence of Donor Age on Graft and Patient Outcomes in Kidney Transplantation: A Systematic Review and Meta-Analysis.
This study pooled earlier research to ask whether an older kidney donor means a worse result for the person who gets the kidney. The authors followed standard review rules (PRISMA 2020) and searched 4 major medical databases. It looked at how long the new kidney keeps working and how long patients live. The excerpt we have does not give the size of the effect, so read the full paper before drawing conclusions about older donor kidneys.
Comparative Cardiorenal Efficacy and Safety of Finerenone, SGLT2 Inhibitors, Semaglutide and Their Combination in Diabetic Kidney Disease.
This review pooled 10 sets of randomized trial data from adults with type 2 diabetes and kidney disease. It compared four options for protecting the kidneys and heart: finerenone, SGLT2 inhibitor drugs, semaglutide, and finerenone taken with an SGLT2 inhibitor. It also compared their side effects. The part of the summary we received cuts off before the results, so we cannot yet say which option did best or by how much.

Salt Intake and Kidney Outcomes in Older Adults With Chronic Kidney Disease: A Stage-Specific Cohort Study.
This study looked at older adults, age 75 and up, with kidney disease. It checked how much salt they ate and how their kidneys did over time. It is an observational study, so it shows a link between salt and kidney decline, but not proof that salt causes it. This helps doctors advise older patients on diet.
Diabetes progression and severe hypoglycemia: a nationwide cohort study of 2,475,605 adults with type 2 diabetes mellitus.
This large study followed 2,475,605 adults with type 2 diabetes. It found that people with more severe diabetes, including those with kidney disease, were more likely to have very low blood sugar. This is an observational study, so it shows a link, not proof of cause. It helps doctors know who is at higher risk.
Selective glomerular hypofiltration syndrome: a novel renal phenotype associated with cardiovascular disease and adverse outcomes in diabetic kidney disease.
Researchers studied 182 people with biopsy-proven diabetic kidney disease. They found a link between a specific kidney filter pattern and heart disease. This study shows a connection, not proof of cause. It helps identify people at higher risk for heart problems.
Speckle Tracking Analysis of the Left and Right Heart in Type 1 Diabetes Patients with End-Stage Renal Disease Awaiting Simultaneous Pancreas-Kidney Transplantation
This preprint looked at heart scans of 16 people with type 1 diabetes and end-stage kidney disease. They were waiting for a combined pancreas and kidney transplant. It is a small observational study, so it shows a link but not proof of cause. It helps doctors understand heart risks before surgery.
Influence of Chronic Kidney Disease on Outcomes After Paclitaxel-Coated Balloon Angioplasty for Coronary In-Stent Restenosis
This study looked at people with kidney disease who had a heart procedure to open blocked arteries. It shows a link between kidney health and how well the heart procedure works. It is an observational study, so it shows a connection but not proof of cause.
Distinct renal adverse event profiles among CDK4/6 inhibitors: a comparative pharmacovigilance analysis
This study looked at safety reports for three cancer drugs. It found that each drug has a different pattern of kidney side effects. This shows a link between the drugs and kidney issues, but it is not proof of cause.
Epidemiology of Critically Ill Patients With Cirrhosis Undergoing Continuous Renal Replacement Therapy: A Contemporaneous Parallel Analysis of the HRS-HARMONY and CRRTnet Registries.
This study looked at 245 people with liver disease who needed dialysis in the ICU. It tracked how they were treated and how many died in the hospital. It shows a link between treatment choices and outcomes. It does not prove that one choice caused the result.
0055Prevalence of Endogenous Hypercortisolism in Individuals With Resistant Hypertension Stratified by Kidney Function: Results From the MOMENTUM Study
This study looked at people with hard-to-control high blood pressure. It checked if high stress hormone levels were linked to kidney function. It found that 27.3% had high stress hormone levels. It shows a link, not proof of cause.
Risk Factors and Short-Term Outcomes of Lower Limb Fractures in Diabetic Patients Presenting to Emergency
