Age is a predominant risk factor for acute kidney injury (AKI), yet the biological mechanisms underlying this risk are largely unknown. Clonal hematopoiesis of indeterminate potential (CHIP) confers increased risk for several chronic diseases associated with aging. Here we sought to test whether CHIP increases the risk of AKI. In three population-based epidemiology cohorts, we found that CHIP was associated with a greater risk of incident AKI, which was more pronounced in patients with AKI requiring dialysis and in individuals with somatic mutations in genes other than DNMT3A, including mutations in TET2 and JAK2. Mendelian randomization analyses supported a causal …

Incidental Ring-Hyperenhancing Liver Micronodules At Ct Hepatic Arteriography-Guided Percutaneous Thermal Ablation Of Colorectal Liver Metastases, Jessica Albuquerque, Yuan-Mao Lin, Iwan Paolucci, Caleb S O'Connor, Ching-Wei Tzeng, Jean-Nicolas Vauthey, Kristy K Brock, Bruno C Odisio

Faculty, Staff and Student Publications

CT during hepatic arteriography (CTHA) is a highly sensitive imaging method for detecting colorectal liver metastases (CLMs), which supports its use during percutaneous thermal liver ablation. In contrast to its high sensitivity, its specificity for incidental small CLMs not detected at preablation cross-sectional imaging is believed to be low given the absence of specific imaging signatures and the common presence of pseudolesions. In this retrospective study of 22 patients (mean age, 55 years ± 10.6 [SD]; 63.6% male, 36.4% female) with CLMs undergoing CTHA-guided microwave percutaneous thermal ablation between November 2017 and October 2022, the authors provided a definition of …

Associations Between Anemia And Fgf23 In The Ckid Study., Elizabeth Thomas, Alexandra M. Klomhaus, Marciana L. Laster, Susan L. Furth, Bradley A. Warady, Isidro B. Salusky, Mark R. Hanudel

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Fibroblast growth factor 23 (FGF23) is a bone-derived hormone that plays a central role in chronic kidney disease-mineral bone disorder and is associated with CKD progression and cardiovascular morbidity. Factors related to CKD-associated anemia, including iron deficiency, can increase FGF23 production. This study aimed to assess whether anemia and/or iron deficiency are associated with increased circulating concentrations of FGF23 in the large, well-characterized Chronic Kidney Disease in Children (CKiD) study cohort.

METHODS: Hemoglobin concentrations, iron parameters, C-terminal (total) FGF23, intact FGF23, and relevant covariables were measured in cross-sectional analysis of CKiD study subjects.

RESULTS: In 493 pediatric patients with …

A Case Of Siadh After Bowel Preparation For Routine Colonoscopy, Joseph C. Rath, Allison M. Hemmer, Kennedy A. Forest, Kahlen R. Morris, Mary E. Watson

Aesculapius Journal (Health Sciences & Medicine)

Electrolyte abnormalities, including hyponatremia, are a known outcome of bowel preparations used for colonoscopy. Severe and symptomatic hyponatremia after bowel preparation is uncommon and occurs due to excessive release of ADH among other contributing factors. Risk factors for developing hyponatremia after bowel preparation include increased age, female gender, kidney disease, heart failure, and use of various medications. We present the case of a 78-year-old female who presented with altered mental status and possible seizures after completing bowel preparation with polyethylene glycol for a colonoscopy. Serum and urine studies were consistent with SIADH. She required fluid restriction, hypertonic saline, and sodium …

Introduction The aetiology of bacterial vaginosis (BV), a biofilm-associated vaginal infection, remains unknown. Epidemiologic data suggest that it is sexually transmitted. BV is characterised by loss of lactic acid-producing lactobacilli and an increase in facultative and strict anaerobic bacteria. Gardnerella spp are present in 95%–100% of cases; Gardnerella vaginalis has been found to be more virulent than other BV-associated bacteria (BVAB) in vitro. However, G. vaginalis is found in women with normal vaginal microbiota and colonisation is not sufficient for BV development. We hypothesise that Gardnerella spp initiate BV biofilm formation, but incident BV (iBV) requires incorporation of other key …

Glomerular diseases are classified using a descriptive taxonomy that is not reflective of the heterogeneous underlying molecular drivers. This limits not only diagnostic and therapeutic patient management, but also impacts clinical trials evaluating targeted interventions. The Nephrotic Syndrome Study Network (NEPTUNE) is poised to address these challenges. The study has enrolled >850 pediatric and adult patients with proteinuric glomerular diseases who have contributed to deep clinical, histologic, genetic, and molecular profiles linked to long-term outcomes. The NEPTUNE Knowledge Network, comprising combined, multiscalar data sets, captures each participant's molecular disease processes at the time of kidney biopsy. In this editorial, we …

A Case Of Occlusive Myocardial Infarction Caused By Nephrotic Syndrome In A 26-Year-Old Type 1 Diabetic, Kyle Admire, Charlotta Jornlid, Chelsea Ryan, Rebecca Pauly

Marshall Journal of Medicine

Nephrotic syndrome is a rare condition distinguished by proteinuria exceeding 3g per day. Other associated characteristics include hematuria, hypoalbuminemia, edema, and hyperlipidemia. There is an array of complications of this syndrome, which are primarily due to the profound losses of protein in the urine. One such complication is thromboembolism, with most documented cases in the form of venous thromboembolism of the extremities which is in part due to urinary loss of antithrombin III and increased synthesis of prothrombotic factors. There are limited available data regarding arterial thrombi and especially few reports about coronary thromboses, which can be life-threatening. In this …

The Yap1/Taz-Tead Transcriptional Network Regulates Gene Expression At Neuromuscular Junctions In Skeletal Muscle Fibers, Lea Gessler, Danyil Huraskin, Yongzhi Jian, Nane Eiber, Zhaoyong Hu, Tomasz J Prószyński, Said Hashemolhosseini

Faculty, Staff and Students Publications

We examined YAP1/TAZ-TEAD signaling pathway activity at neuromuscular junctions (NMJs) of skeletal muscle fibers in adult mice. Our investigations revealed that muscle-specific knockouts of Yap1 or Taz, or both, demonstrate that these transcriptional coactivators regulate synaptic gene expression, the number and morphology of NMJs, and synaptic nuclei. Yap1 or Taz single knockout mice display reduced grip strength, fragmentation of NMJs, and accumulation of synaptic nuclei. Yap1/Taz muscle-specific double knockout mice do not survive beyond birth and possess almost no NMJs, the few detectable show severely impaired morphology and are organized in widened endplate bands; and with motor nerve endings being …
