Cardiovascular safety of orforglipron versus insulin glargine in adults with type 2 diabetes at increased cardiovascular risk (ACHIEVE-4): a phase 3, event-driven, randomised, open-label, non-inferiority, active comparator trial.
Klein KR, Wysham C, Tuttle KR, Davies MJ et al. | 2026 Sep 30 | Phase 3, randomized, open-label, non-inferiority trial. | DOI: 10.1016/S0140-6736(26)01865-9
AI Clinical Summary
Orforglipron, an oral non-peptide GLP-1 receptor agonist, demonstrated cardiovascular non-inferiority to insulin glargine (HR 0.84; 95% CI 0.59–1.20) in adults with T2D and high CV risk, including 37.6% with CKD. While orforglipron significantly reduced hypoglycemia risk compared to insulin, it was associated with frequent gastrointestinal adverse events (62.1%) leading to treatment discontinuation. The open-label design and relatively short 2-year median follow-up are notable limitations regarding long-term outcomes.Clinical relevance: High

Donor Self-Esteem Before and After Living Kidney Donation.
Neumann R, Arnold JB, Boudville N, Cuerden MS et al. | 2026 Sep 28 | Prospective multicenter cohort study. | DOI: 10.1053/j.ajkd.2026.05.023
AI Clinical Summary
In 941 donors, self-esteem remained high over 5 years, with low self-esteem occurring in only 2-4% post-donation. While predonation depression predicted lower post-donation self-esteem, donors with lower baseline scores showed modest improvements associated with reduced anxiety and depression. A key limitation was the lack of analysis regarding the impact of recipient graft failure or death on donor psychological outcomes.Clinical relevance: High

Perceptions of Hispanic Patients With Advanced CKD About Communication and Engagement Regarding Kidney Transplantation: A Qualitative Study.
Gupta A, Bansal A, Fielding-Gebhardt H, Baker C et al. | 2026 Oct | Qualitative study | DOI: 10.1053/j.ajkd.2026.04.017
AI Clinical Summary
Spanish-speaking Hispanic patients reported insufficient communication regarding transplant eligibility and socioemotional well-being, leading to fear and uninformed decision-making. While interpreters mitigated language barriers, gaps in social context and clinical engagement persisted. Findings are limited by a small sample size and lack of national representation.Clinical relevance: High

Executive Summary of the ASN Kidney Health Guidance on the Cardiovascular‑Kidney‑Metabolic Syndrome.
Navaneethan SD, Rifkin B, Mottl AK, on behalf of the ASN Kidney Health Workgroup on the Cardiovascular-Kidney-Metabolic Syndrome | 2026 Oct 01 | Practice Guideline | DOI: 10.1681/ASN.0000001230
AI Clinical Summary
This guidance advocates for a multidisciplinary approach to Cardiovascular-Kidney-Metabolic syndrome, emphasizing the PREVENT equation and foundational therapies like RAS inhibitors and SGLT2 inhibitors. It aims to reduce cardiovascular morbidity through rapid treatment sequencing and lifestyle modifications. However, evidence remains limited for pediatric, transplant, and dialysis populations.Clinical relevance: High

The Polycystic Kidney Disease Cyst Transcriptome Defined by Integrating Spatial, Single Nuclear, and Bulk Transcriptomics.
Khan MI, Robichaud JH, Afrin H, Chebib FT et al. | 2026 Sep 28 | Multi-omic spatial transcriptomics study. | DOI: 10.34067/KID.0000001371
AI Clinical Summary
Integrating spatial, single-nuclear, and bulk RNA-seq, researchers identified musculin as a specific cystic anchor gene and mapped interactomes involving TGF-β and mTORC2 signaling. This defines the cyst-specific transcriptome and ligand-receptor crosstalk between cysts and fibroblasts, though findings require further validation in larger cohorts and functional models.Clinical relevance: High

Humoral and Cellular Immune Responses Following Bivalent SARS-CoV-2 mRNA Vaccines in Patients Undergoing Hemodialysis: A Prospective Cohort Study.
Ling TC, Chen PL, Wang JR, Ko WC et al. | 2026 Oct | Prospective observational cohort study | DOI: 10.1016/j.xkme.2026.101480
AI Clinical Summary
Bivalent mRNA boosters significantly increased antibody titers and neutralized emerging Omicron subvariants in hemodialysis patients, matching healthy controls. However, cellular immunity remained suboptimal (58.1% positive IGRA) despite multiple exposures, and antibody levels halved by three months. Limitations include a small, heterogeneous sample.Clinical relevance: High

Giredestrant plus Everolimus in Advanced Breast Cancer.
Mayer EL, Tolaney SM, Martín M, Vidal GA et al. | 2026 Oct 01 | Phase 3, multicenter, randomized controlled trial. | DOI: 10.1056/NEJMoa2602457
AI Clinical Summary
Giredestrant plus everolimus significantly improved progression-free survival (8.8 vs 5.5 months) in ER+/HER2- advanced breast cancer post-CDK4/6 inhibition, particularly in ESR1-mutated tumors. This all-oral regimen offers a potent alternative to standard endocrine combinations, though nearly all patients experienced adverse events, primarily stomatitis and diarrhea. The study was open-label, potentially impacting investigator-assessed outcomes.Clinical relevance: Low

Resistant Hypertension: State of the Art Review.
Khan MS, Arshad MS, Hall ME, Jafar TH et al. | 2026 Oct 02 | State-of-the-art review. | DOI: 10.2215/CJN.0000001266
AI Clinical Summary
Resistant hypertension requires excluding pseudo-resistance via ambulatory monitoring before escalating to fourth-line mineralocorticoid receptor antagonists. While new agents like aprocitentan and renal denervation expand options, clinical impact depends on managing CKD-specific risks like hyperkalemia and volume status. The review is limited by the need for further evidence on phenotype-guided, precision-based treatment strategies.Clinical relevance: High

Impact of African-enriched GATM regulatory variants on creatinine-derived estimated glomerular filtration rate.
Gray OA, Yerges-Armstrong L, Castel SE, Brandenburg JT et al. | 2026 Oct | Genomic association and biomarker validation study. | DOI: 10.1016/j.kint.2026.06.038
AI Clinical Summary
African-enriched GATM variants increase creatine synthesis, causing higher serum creatinine and lower eGFRCr (2 mL/min/1.73m² per allele) independent of true GFR. This biomarker-specific bias leads to CKD overdiagnosis in African ancestry populations without increasing risk for end-stage kidney disease. A limitation is the study’s focus on specific African cohorts, requiring broader validation across diverse global populations to refine clinical GFR estimation.Clinical relevance: High

Improving Access to Transplant: A Quality Improvement Initiative to Reduce Time From Outpatient Dialysis Initiation to Deceased Donor Kidney Transplant Activation.
Chati P, Whittington J, Braden K, Priya S V et al. | 2026 Oct | Quality Improvement Study | DOI: 10.1111/petr.70473
AI Clinical Summary
A single-center pediatric initiative using multidisciplinary clinics and enhanced coordination reduced median dialysis-to-transplant activation time from 211.5 to 130.5 days. This demonstrates that addressing communication and educational barriers can significantly accelerate transplant readiness, though findings are limited by a small sample size (n=10) and single-center design.Clinical relevance: Moderate
