Patients at centers conducting quality improvement projects, (OR [95% CI]) 1.94, [1.36-2.76]), offering assisted PD (1.89, [1.39-2.57]), fostering staff research engagement (1.35, [1.03-1.77]) or hosting HT roadshows (1.22, [1.05-1.41]) had higher odds of HT uptake.

Efforts to limit correction to ≤8 mmol/L per day in patients at high risk of developing ODS became common practice. Recent studies have questioned these guidelines, suggesting that ODS is rare and that slow correction may increase mortality. In this review, we revisit the history of the controversy and find that these claims have persisted for four decades. Older studies supporting faster correction are flawed by referral bias while newer studies are limited by confounding as comorbidities influence rates of both mortality and hyponatremia correction. While both old and new studies emphasize the rarity of MRI-documented ODS after rapid correction, they were not conducted in hyponatremic patients who were at risk for ODS. Old studies reporting hyponatremic deaths due to cerebral edema overestimate its true incidence and new studies reporting an association of mortality and slow rates of sodium correction do not document cerebral edema as a common contributor to death. Further research is required to better define the incidence of both ODS and cerebral edema in patients at risk for these complications. Until then, we conclude that the risks of rapid correction-including irreversible neurological damage-necessitate caution. Clinicians should continue to prioritize slow, controlled sodium correction to protect high-risk patients from harm.","PeriodicalId":7419,"journal":{"name":"American Journal of Kidney Diseases","volume":"55 1","pages":""},"PeriodicalIF":13.2,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145296210","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}

The climate impact from a patient receiving HD was 74% and 46% more than from patients receiving KT and PD, respectively. Similarly, HD accounted for 65% of total air pollution impacts, 54% of human toxicity, and 44% of water depletion. The highest impact of PD was on water depletion (41%) and metal depletion (81%).

Decision aids improve decisional quality and goal-concordant care among older patients with chronic kidney disease (CKD). However, decision aids for kidney replacement therapy have yet to be adapted for the older Latino adult population with advanced CKD. The objective of this study was to assess the acceptability, accessibility and adaptions needed to facilitate use of a Spanish version of the Decision-Aid for Renal Therapy (DART-S) for older Latino adults with advanced CKD.STUDY DESIGNQualitative study applying the Cultural Targeting and Tailoring of Shared Decision-Making Technology Framework in focus group and structured interviews.

Overall, participants found DART-S to be acceptable and accessible. Thematic analysis revealed the importance of incorporating lived experiences, including patient and family testimonials, to illustrate the mental health impact of CKD, self-care strategies, and home dialysis adaptations. Some found the delivery of prognostic information distressing, highlighting the need for more sensitive communication. Tailoring recommendations included information about financial barriers, nutrition, and lifestyle.

Whilst acknowledging these challenges, GSK decided to adopt the CKD-EPI 2021 eGFRcr equation for new adult trials to support health equity and delivery benefits from standardized data management. The eGFRcr obtained using the CKD-EPI 2021 equation versus CKD-EPI 2009 equation is moderately lower in US Black individuals and moderately higher in non-Black individuals.
