Nephrogenic systemic fibrosis (NSF) is a devastating complication of severe renal failure. Recent reports suggest that exposure to gadolinium-containing contrast agents (GCCA) is associated with the occurrence of NSF. The population of patients with ESRD in and around Bridgeport, CT, was studied during an 18-mo period. The incidence of NSF was 4.3 cases per 1000 patient-years. Each radiologic study using gadolinium presented a 2.4% risk for NSF. The association between gadolinium exposure and NSF was highly significant (P < or = 0.001). It is concluded that GCCA exposure is a major risk factor for NSF in the ESRD population. Because of the significant morbidity and mortality with NSF, it is believed that gadolinium exposure should be avoided in patients with ESRD. In the event that exposure cannot be avoided, careful consideration of the potential consequences, including a thorough discussion of the risks and benefits of GCCA, is advised.

Improving the understanding of how chemicals affect on organisms and assessing the associated environmental risks is of major interest in environmental studies. This can be achieved by using complementary approaches based on the study of the molecular responses of organisms. Because of the known chemical pressures on the environment, regulations on the content of some chemicals, such as cadmium, have been mostly completed.

Background: We examined chronic gadolinium retention impact on gene expression in the mouse central nervous system (CNS) after injection of linear or macrocyclic gadolinium-based contrast agents (GBCAs).
Methods: From 05/2022 to 07/2023, 36 female mice underwent weekly intraperitoneal injections of gadodiamide (2.5 mmol/kg, linear), gadobutrol (2.

The use of rare earth elements has increased in recent years, leading to a rise in environmental concentrations. Despite the growth in number of studies regarding toxicity, knowledge gaps remain. For Daphnia magna, standardized test methods involve exposure periods of either 48 h or 21 days to assess toxicological effects.

Objectives: To investigate the associations between gadolinium-based contrast agent (GBCA) administration and the occurrence of acute kidney injury (AKI) in pediatric patients, and to determine the risks associated with AKI.
Materials And Methods: This retrospective study was conducted on pediatric patients who underwent contrast-enhanced or unenhanced MRI between January 1st, 2015, and June 30th, 2021. Examinations were included if they had data on height and serum creatinine levels within 3 months before and 2 days after the examinations.

The mobilization of rare earth elements (REEs) in aquatic ecosystems is expected to rise significantly due to intensified exploitation, erosion, and climate change. As a result, more attention has been brought to study their environmental fate. However, our ability to assess contamination risks in freshwater organisms remains limited due to scarce data on the composition and accumulation of REEs.
