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.
Today brought no new kidney research, so the day is one for steady habits
-
One animal study reported a Chinese herbal formula slowing muscle loss in rats, which is far too early to mean anything for people.
Some days the research world simply does not produce kidney news, and this is one of them. The closest item is a review weighing three eating patterns for people living with both obesity and kidney disease, and it leans toward whole patterns you can actually stick with rather than strict single-nutrient rules. Everything else that came in studied other conditions, or studied animals, so it cannot be stretched to cover kidneys. A quiet day is a reasonable time to check in with your care team about the plan you already have.
Remotely Delivered Nutrition Interventions with or Without Physical Activity Interventions in Adults with Cardiovascular Diseases: A Systematic Review of Randomized Controlled Trials.
This review pulled together randomized trials of diet coaching delivered at a distance, by phone or app, for adults with heart disease. Some trials added exercise coaching on top. The review reports these remote programs can shift eating and activity habits. It covers heart disease only, with no kidney patients and no kidney measurements.
Efficacy of desmopressin in reducing post-procedural bleeding among chronic kidney disease patients: a systematic review and meta-analysis.
Researchers pooled results from randomized trials, searching three medical databases through August 2025, to test whether the drug desmopressin cuts bleeding when people with chronic kidney disease have surgery or a procedure. Kidney disease makes the blood's clotting cells work poorly, so bleeding is a real risk. Desmopressin is already given for this, but doctors were not sure it worked. Pooling randomized trials is the strongest kind of evidence, so this gives a clearer answer than any single trial did.
Abdominal aortic calcification index and prognosis in patients with chronic kidney disease: a meta-analysis
This review pooled many earlier studies that scored calcium buildup in the main artery of the belly on scans in people with kidney disease. It asked whether a higher score goes with worse outcomes later, such as heart problems and death. The pooled studies watched people over time rather than testing a treatment, so the pattern is a strong link, not proof that the calcium itself does the harm. A scan score like this could help flag who needs closer watching.
The Effects of Guided Imagery on Women's Health: A Systematic Review of Experimental Studies.
This review gathered experimental studies of guided imagery in women, a relaxation practice that uses vivid mental pictures. It looked at cancer care, pregnancy, childbirth and menopause, and reported effects on mood and body measures. The review does not cover kidney disease, and it pools small studies rather than one large trial. Nothing here tells you whether guided imagery helps kidneys.
Renal Safety of Intravitreal Ranibizumab and the Effects of SGLT2 Inhibition in Diabetic Macular Oedema: A Post Hoc Analysis of the COMET Trial.
This is a follow-up look at 53 people from the COMET randomized trial, all with swelling in the back of the eye from diabetes. Researchers checked whether eye injections of the drug ranibizumab affected the kidneys over 48 weeks, tracking kidney filtering rate (eGFR), protein in the urine, and red blood cell levels. They also checked whether SGLT2 inhibitor drugs showed their usual kidney and blood effects in this group. The study is small and was not designed to answer this question up front, so it is a safety signal check rather than firm proof.
Effects of Brussels Chicory and Concurrent Exercise Training on HDL Function and Subclass Profiles in Overweight College Students: A Pilot Randomized Controlled Trial.
This was a small pilot study in overweight college students who were split at random into three groups. One group took a supplement made from Brussels chicory, a leafy vegetable rich in plant compounds called phenolic acids. The other two added either supervised exercise or exercise with mindfulness training on top of the supplement. The report we have does not give the number of people or how long it ran, and it measured lab markers of good cholesterol function rather than any health outcome.
Association of Domain-Specific Physical Activity with Sleep Disorders in U.S. Adults: A Cross-Sectional Study Based on NHANES.
This study looked at 25,732 American adults, average age about 50, in a national health survey. It compared sleep problems against activity at work, activity while getting around, and activity in free time. Because everyone was measured at one moment in time, it can only show a link, not prove that exercise changes sleep. There is no kidney angle here.
Dietary Patterns for Obesity in CKD: Mediterranean, Low-Carbohydrate, and Plant-Forward Approaches-What Fits Best?
This review compares three ways of eating for people who have both obesity and kidney disease: the Mediterranean diet, mostly-plant diets, and low-carb or keto diets. Extra weight and kidney disease make each other worse, and older advice that just cut single nutrients often left people with poor nutrition or a plan they could not stick to. The authors argue whole eating patterns fit better, but this is a summary of other studies, not a new trial. It shows which patterns look promising, not proof that one of them protects kidneys.
Spiritual Well-Being as a Patient-Reported Assessment Dimension in Advanced Cancer: Clinical Validation and Quality-of-Life Implications.
Researchers tested a questionnaire that measures spiritual well-being in people with advanced cancer. They found that scores on it lined up with quality of life scores. This shows a link between the two, not proof that one causes the other. The study is about cancer care, not kidney disease.
A Mobile Application Intervention for Emotional Health in Older Adults: Designed for Dementia Prevention.
Adults aged 60 and over, none of whom had dementia, used a phone app called MELI built to protect thinking skills. Researchers measured depression, anxiety and life satisfaction before and after. The abstract does not show a comparison group chosen at random, so this shows a link at best, not proof the app caused the change. It has nothing to do with kidney disease.
Cumulative metabolic burden and urinary albumin-to-creatinine ratio in non-diabetic adults: a nationwide population-based study.
This nationwide study looked at adults without diabetes and asked whether piling up metabolic problems over time tracks with early kidney damage. The damage marker is albumin in the urine, a protein that leaks out when the kidney's filters are strained. People with more metabolic burden had higher levels of that protein. This is an observational snapshot, so it shows a link, not proof that one causes the other.
Association of neutrophil-to-lymphocyte-platelet ratio with residual renal function in early-stage peritoneal dialysis patients.
This study tested a blood measure that combines three cell counts: neutrophils, lymphocytes and platelets. In people on peritoneal dialysis, a home form of dialysis, a higher number went along with less leftover kidney function of their own. Patients were split into a group on dialysis 3 to 12 months and a group past 12 months. It was a look back at medical records, so it shows a link, not proof that inflammation causes the loss.
Sex differences in cardiac function and remodelling in patients with preserved left ventricular ejection fraction across all stages of chronic kidney disease.
Doctors reviewed heart scans from 84 people with kidney disease across all five stages, matched for sex, plus healthy people for comparison. Everyone had normal heart pumping strength, so the study looked instead at changes in the heart's shape and how it fills. Women and men with kidney disease showed different patterns of change. This is a look back at old records, so it shows a link between sex and heart changes, not proof that one causes the other.
Finerenone Use in Heart Failure Patients with Type 2 Diabetes and Kidney Disease: An Analysis of the FINE-TURK Registry.
Doctors in Turkey reviewed records from the FINE-TURK registry to see how the drug finerenone performed in people who have type 2 diabetes, kidney disease and heart failure all at once. Finerenone is known to protect the heart and kidneys in diabetes with kidney disease, but people with heart failure were barely studied before. The report describes who these patients were and what happened to their kidneys over a short follow-up. It is a look-back at real-world records, so it shows patterns, not proof that the drug caused the results.
Profile, follow-up adherence and progression of people with advanced chronic kidney disease in specialized care centers: a retrospective study, Santa Catarina state, Brazil, 2021-2024.
Researchers looked back at medical records from five kidney clinics in Santa Catarina, Brazil, covering people treated between November 2021 and October 2024. Everyone had stage 4 or stage 5 kidney disease, which is advanced. The team described who these patients were, how many kept coming to appointments, and how their kidney filtering rate (eGFR) changed after one year of specialist care. This kind of look-back study can show a link between staying in care and kidney results, but it cannot prove the care caused the difference.
Associations Among Caregiver Burden, Mindful Self-Care, and Health Perception in Informal Caregivers of Patients With Chronic Kidney Disease: A Cross-Sectional Study.
This study surveyed unpaid family caregivers of people with chronic kidney disease at a single point in time. It measured how heavy the caregiving load felt, how healthy caregivers rated themselves, and how much they practiced mindful self-care, meaning paying attention to their own needs on purpose. The researchers found these three things are linked to each other. A one-time survey shows a link only. It cannot tell us whether self-care makes caregivers healthier or whether healthier caregivers simply have more room for self-care.
Reciprocal mediation of immuno-inflammation and insulin resistance in the risk of chronic kidney disease among patients with coronary artery disease: insights from neutrophil-to-lymphocyte ratio and triglyceride-glucose index
In people with clogged heart arteries, researchers checked two cheap blood markers: one for inflammation, based on the ratio of two white blood cell types, and one for insulin resistance, based on blood fat and blood sugar. Higher levels on both tracked with a higher chance of having chronic kidney disease, and each one seemed to carry part of the other's effect. That fits the idea that inflammation and blood sugar problems feed each other and wear on the kidneys. This is an observational study, so it shows a link, not proof that either marker causes kidney damage.
Birth characteristics and growth outcome in children with nephropathic cystinosis compared with other chronic kidney disease entities prior to kidney replacement therapy
Researchers compared birth size and later growth in children with nephropathic cystinosis, a rare inherited disease that damages the kidneys, against children with other kinds of chronic kidney disease. All the children were still before dialysis or a transplant. The comparison points to differences in how these children grow, which matters because poor growth is a warning sign in childhood kidney disease. This is an observational study, so it shows a link and not proof of cause.
Random Urinary Calcium/Creatinine Ratio as a Predictor of Dehydration in Hypercalcemic and Normocalcemic Patients
This study tested whether one urine sample, comparing calcium against creatinine, can flag dehydration. Creatinine is a waste product used to judge how concentrated the urine is. It is an observational study, so it shows a link, not proof of cause. Spotting dehydration early matters because it can injure the kidneys.
Cardio-Renal Interaction Between NT-proBNP and Renal Function Across Chronic Kidney Disease Stages in Patients with Heart Failure
This study looked at NT-proBNP, a blood marker of heart strain, in people with heart failure at different stages of kidney disease. Weak kidneys raise this marker on their own, which makes the heart test harder to read. It is an observational study, so it shows a link between kidney function and the marker, not proof of cause.
