We sought to define the precise relationship between SGLT2i exposure, types of urinary tract infections (UTI), and clinical risk factors.METHODSWe used an incident user design with active comparator analysis to derive SGLT2i and glucagon-like peptide-1 receptor agonist (GLP1ra) user cohorts from US nationwide insurance claim data. We used both covariate-adjusted Cox models and Cox models with inverse probability of treatment weighting to investigate the risk of non-candida UTI and candida UTI following drug exposure. We compared the risk between SGLT2i and GLP1ra exposure in the general population and subpopulations with genitourinary abnormalities.RESULTSGLT2i exposure compared with GLP1ra exposure was associated with a greater risk of candida UTI (all hazard ratios [HRs] ≥2.42 and all P-values <0.001), but a lower risk of non-candida UTI (all HRs ≤0.91 and all P-values <0.001). Prior genitourinary abnormalities such as prior UTI, prior genital infection, genitourinary malignancy, indwelling foley, or other genitourinary pathology were associated with greater risk of non-candida and/or candida UTI (all adjusted HRs ≥1.26 and all P-values ≤0.002). However, no difference in comparative risk of SGLT2i to GLP1ra exposure for non-candida UTI was observed in these subpopulations. In contrast, an additive effect between SGLT2i exposure and several genitourinary abnormalities was observed for candida UTI (all adjusted HRs ≥2.37 and all P-values <0.001).CONCLUSIONSSGLT2i exposure was associated with greater risk of candida UTI, but not non-candida UTI.

Kidney replacement therapy (KRT) decision readiness is associated with higher selection and use of home dialysis; however, KRT decision-making is complex, and factors informing KRT decision readiness in patients with advanced chronic kidney disease (CKD) are unclear.METHODSUsing the baseline data of the Trial to Evaluate and Assess the effects of Comprehensive KRT-directed patient education on Home dialysis use among VETerans (TEACH-VET), we conducted a cross-sectional analysis to evaluate prevalent KRT decision readiness, defined as ability to choose any KRT modality among US Veterans with advanced CKD. We also evaluated Veterans' ability to achieve high-quality informed KRT decisions (more than 60% decisional confidence on a scale ranging from 1 to 100%) and selection of home dialysis as secondary outcomes. Univariate and multivariable logistic regression were used to test associations between patient-level variables and outcomes.RESULTSOf the 468 enrollees with a complete baseline dataset, 282 (60%) could not pick any KRT modality; the rest were split between high (20%) vs. low-quality (20%) decisions and home (21%) vs. in-center (19%) dialysis. Younger age, higher CKD stage, history of receiving prior KRT-directed education, rural habitation, and objective disease knowledge were positively associated with KRT decision readiness. Only objective disease knowledge was associated with KRT decision readiness after adjustments, with participants in the highest tertile of CKD-specific knowledge having two-fold (OR: 2.31, 95%CI: 1.18, 4.55) and KRT-specific knowledge having five-fold (OR: 5.16, 95%CI: 2.63, 10.32) higher odds of selecting their KRT. Item-level analysis showed that difficult, specifically KRT knowledge-related, items had a high discriminatory capacity to predict KRT decision readiness.CONCLUSIONVeterans with advanced CKD are ill-prepared for KRT decision-making. While social determinants of health have a potential role in identifying high-risk populations, objective kidney failure and KRT-specific knowledge have a dominant impact on KRT decision readiness.","PeriodicalId":50681,"journal":{"name":"Clinical Journal of the American Society of Nephrology","volume":"6 1","pages":""},"PeriodicalIF":9.8,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143824781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Children and adults were analyzed separately in four cohorts 1) full, 2) incident, 3) prevalent, and 4) histology.

However, the process of consenting a patient to a procedure or intervention is often unstandardized, leading to gaps in comprehension, which in turn affects decision-making. This study aimed to assess the patient-reported benefits of video-assisted electronic consent (eConsent) compared with the usual consent practices for percutaneous kidney biopsies (PKB).METHODSIn this single-center, open-label, randomized controlled trial, consecutive patients undergoing PKB between July 2021 and January 2024 were randomized (1:1) to either video-assisted eConsent (intervention) or usual practice of consent (control). The intervention group accessed an eight-minute explanatory animation on an online platform covering the procedure, its risks, and pre- and post-biopsy care before providing digital consent. The control group was consented to by clinicians in the usual manner and signed a paper form. The primary outcome was questionnaire-based patient comprehension, with secondary outcomes including patient-reported experience, anxiety, and satisfaction with the consent process.RESULTSOf 178 eligible patients, 120 were enrolled (60 in each group), with a median age of 52 (IQR 34-65) years, 56% were female, and 59% had less than 12 years of education.

Comprehension did not differ significantly by sex or education level, but younger patients scored higher. The eConsent group also had better comprehension of pre- and post-PKB care.

We utilized panel regression models with individual and year fixed effects to evaluate how exposure to different levels of temperature (measured by heat index) was associated with changes in weekly healthcare utilization from October 1, 2015, to March 31, 2023. Data were derived from medical claims data, Parameter-Elevation Regressions on Independent Slopes Model (PRISM) climate data, and the Census block group of each individual. The study population was comprised of 916,886 individuals with commercial or Medicare insurance who had been diagnosed with CKD stage G3, G4, or G5.

Exposure was the number of days in a week with a daily heat index in ten-degree Fahrenheit bins. Results: We found that exposure to a higher heat index bin, 90-100F compared to 60-70F, was associated with an increase in weekly emergency department utilization (0.55%; 95% CI: 0.42%-0.68%; p<0.001), with larger percent increases for ED visits with a heat-related primary diagnosis code (2.07%; 95% CI: 1.63%-2.51%; p<0.001) or a kidney-related primary diagnosis code (1.37%; 95% CI: 0.56%-2.17%; p <0.001).
