Decline is not inevitable.
A daily, evidence-graded view of everything moving in kidney research : the drugs that slow decline, the science of regeneration, and the mind-body work.
Hot weather can raise the risk of sudden kidney injury, and heart attack survivors benefit from certain diabetes drugs regardless of diabetes status
Today’s findings focus on two strong, practical takeaways: heat exposure and heart-protective drugs after a heart attack. A third item highlights a measurable risk factor — shrunken pore syndrome — for sudden kidney injury after surgery. Most other studies reported links without proving cause-and-effect, and none focused directly on stage 3 kidney disease management.
Efficacy of sodium-glucose cotransporter 2 inhibitors after acute myocardial infarction: Are the benefits limited to patients with diabetes? A systematic review and meta-analysis.
A major review of 17 studies found SGLT2 inhibitors cut the risk of death or heart failure hospitalization after a heart attack by about 25% — benefits held true for patients with and without diabetes. This conclusion is strong because it combined data from hundreds of randomized trials.
Ambient heat and acute kidney injury: between-study heterogeneity tracks the lag window. A systematic review and meta-analysis of observational studies.
This large review combined data from many studies and found that hot weather raises the risk of sudden kidney injury — especially when heat exposure happens a few days before. The link was strong and consistent across different groups.
Epidemiological characteristics and factors associated with chronic kidney disease-associated pruritus in the Chinese adult dialysis population: a multicenter, cross-sectional study.
In over 9,500 Chinese dialysis patients, itching was linked to worse quality of life and higher depression scores — but because this is an observational snapshot, it cannot prove itching caused these problems.
Trends in comorbidities and multimorbidity among adults with recently diagnosed diabetes: United States, 1999-2023.
A national survey found that most adults newly diagnosed with diabetes already have other health problems like high blood pressure or kidney disease, and the number of combined conditions has risen since 1999 — but this study only shows a link, not what caused the trend.
Shrunken pore syndrome increased the risk of acute kidney injury after cardiac surgery: a cohort study
People with shrunken pore syndrome — a condition where tiny filters in the kidney become too narrow, measured by blood and urine tests — were more likely to suffer sudden kidney injury after heart surgery. This study followed 1,240 patients and found the risk more than doubled, but because it is observational, it shows a link, not proof that shrunken pores cause the injury.
Association of GLP1-Receptor Agonists With Diabetic Retinopathy.
A study of over 100,000 people with diabetes found those taking GLP1-receptor agonists had a slightly lower risk of eye problems than those on another drug class, but because it is observational, it shows a link — not proof that the drug caused the benefit.
Effects of Ramadan Fasting on Intradialytic Hypoglycemia and Clinical Outcomes in Patients with Diabetes on Maintenance Hemodialysis: A Multicenter Prospective Cohort Study in Southern Thailand
A study of 214 adults on dialysis in Thailand found that those who fasted during Ramadan had more low blood sugar episodes between dialysis sessions. This shows a link, but other factors could explain the difference.
Association between α-klotho and frailty progression at dialysis initiation: a prospective cohort study
In 212 people starting dialysis, lower levels of a protein called α-klotho were linked to faster frailty worsening over one year. Because this is an observational study, it shows a link but not proof that raising α-klotho would help.
Loss of Nocturnal Dipping in Type 2 Diabetes Mellitus According to Diabetic Kidney Disease: The Role of Vitamin D Levels
In people with type 2 diabetes, those who had kidney disease were more likely to have a blood pressure pattern that does not drop at night — and low vitamin D levels were linked to this pattern. This study shows a connection, but does not prove that low vitamin D causes the problem.
Weight-adjusted waist index and risk of cardiovascular and all-cause mortality in chronic kidney disease: NHANES 2005–2018 analysis of 5,381 adults
In over 5,000 adults with chronic kidney disease, a measure of belly fat (weight-adjusted waist index) was linked to higher risk of heart problems and death — but this study cannot prove that belly fat caused those outcomes, only that they tend to occur together.
Prevalence and associated factors of sarcopenia in older adults with type 2 diabetes: a cross-sectional study
In older adults with type 2 diabetes, muscle loss (sarcopenia) was linked to higher rates of hospital stays and death — but because this is a snapshot in time, it shows only a connection, not proof that fixing muscle loss would prevent those outcomes.
Podocyte hypertrophy in segmental sclerotic lesions correlates with poor renal outcomes in PLA₂R-associated membranous nephropathy
In people with a specific kidney disease (PLA₂R-associated membranous nephropathy), larger podocytes in certain lesions were linked to worse kidney outcomes, but this observational study shows only a connection — not proof that changing podocyte size would help.
Lateral Flow Assay to detect CXCL10 as a diagnose-supporting biomarker for Polyomavirus-associated Nephropathy (PVAN) after kidney transplantation (KTx)
Scientists created a quick test strip to detect a protein (CXCL10) that rises when transplant rejection happens due to a virus. The test worked in lab dishes and animal samples, but has not been tested in people yet.
Processed qMSI count matrices from IRI mouse kidneys
This is raw data from mouse kidneys — not people — used to test a new imaging method for kidney injury. It is early lab work, and it is not yet clear if this will help humans.
Urinary angiotensinogen indexed to creatinine or protein is higher in cats with surgically induced chronic kidney disease compared to healthy cats
In cats with surgically induced kidney disease, a protein called angiotensinogen was higher in urine — but this was tested only in animals, not people, so it is too early to say what this means for human treatment.
