Free-breathing qRF-MRF with pilot tone respiratory motion navigator for T, T, T*, and off-resonance mapping of the human body at 3 T.

Standard quantitative abdominal MRI techniques are time consuming, require breath-holds, and are susceptible to patient motion artifacts. Magnetic resonance fingerprinting (MRF) is naturally multi-parametric and quantifies multiple tissue properties, including T and T. This work includes T* and off-resonance mapping into a free-breathing MRF framework utilizing a pilot tone navigator.

Acyl-CoA thioesterase 13 () attenuates the progression of autosomal dominant polycystic kidney disease via triggering mitochondrial-related cell apoptosis.

Purpose: Autosomal dominant polycystic kidney disease (ADPKD) is the most common cause of end-stage kidney disease. It has been shown that Acyl-CoA thioesterase 13 () level was reduced in renal cystic tissues from ADPKD patients. However, the role of in ADPKD remains largely elusive.

Advancing the molecular understanding of renal tumorigenesis: Acquired cystic disease-associated renal cell carcinoma (ACD-RCC) as a model system.

In summary, the study's investigation of KMT2C and TSC2 variants in ACD-RCC marks a significant advancement in comprehending this distinct kidney tumor. By illuminating the molecular landscape of ACD-RCC, the research sets the stage for future studies aimed at revealing the complex mechanisms driving tumor development and progression. This understanding could eventually lead to more effective management and treatment strategies for renal cancer patients.

Malignant Tumors Identified in Adult Polycystic Kidney Disease Can Be Derived from Both Proximal Tubular and Distal Tubular Origins.

Unlabelled: Adult polycystic kidney disease (APKD) is a genetic disorder leading to premature renal dysfunction and failure. The prevalence of malignant renal tumors occurring in the APKD setting has been rarely reported.

Objective: To better characterize malignant renal tumors in nephrectomy specimens of APKD and apply modern pathologic evaluation.

Increased level of TXNIP and nuclear translocation of TXN is associated with end stage renal disease and development of multiplex renal tumours.

Background: End-stage and acquired cystic renal disease (ESRD/ACRD) kidneys are characterized by inflammatory remodelling and multiplex renal cell carcinomas (RCC). Eosinophilic vacuolated tumour (EVT) occurs exclusively in ACRD. The aim of this study was to identify the involvement of thioredoxin-interacting protein (TXNIP) and thioredoxin (TXN) in ESRD/ACRD pathology.

[Acquired cystic kidney hemorrhage in peritoneal dialysis patients: A report of three cases].

Spontaneous renal cyst hemorrhage is one of the clinical emergencies in peritoneal dialysis (PD) patients and is potentially life-threatening. The main complaints are sudden low back pain, paleness, and hypotensive shock with or without vomiting or fever. In contrast to inherited polycystic kidney disease, acquired cystic kidney disease (ACKD) secondary to chronic kidney disease is easily overlooked or delayed in clinical diagnosis and treatment, leading to severe clinical outcomes.

Acquired cystic disease associated renal cell carcinoma: A clinicopathologic and molecular study of 31 tumors.

Acquired cystic disease associated renal cell carcinomas (ACD-RCC) are rare and their molecular and histopathological characteristics are still being explored. We therefore investigated the clinicopathologic and molecular characteristics of 31 tumors. The patients were predominantly male (n = 30), with tumors mainly left-sided (n = 17), unifocal (n = 19), and unilateral (n = 29) and a mean tumor size of 25 mm (range, 3-65 mm).

Erythrocytosis and CKD: A Review.

Erythrocytosis or polycythemia is defined as an increase in red blood cell concentration above the age- and sex-specific normal levels. Unlike anemia, which is very common in patients with chronic kidney disease (CKD), erythrocytosis is less frequent but requires specific understanding by health care professionals in order to provide the best care. Erythrocytosis, especially when undiagnosed and untreated, can lead to serious thrombotic events and higher mortality.

Incidental finding of acquired cystic kidney disease associated renal cell carcinoma in an adolescent with kidney failure.

Acquired cystic kidney disease (ACKD) can occur in patients with chronic kidney disease and kidney failure, and its incidence increases with the duration of dialysis. In adults, ACKD is less common in the pre-dialysis group (~ 7%), but its incidence can be as high as 80% for those who are on dialysis for more than ten years. There is, however, very little information about the prevalence of ACKD in children.

Acquired Cystic Disease-Associated Renal Cell Carcinoma: A Systematic Review and Meta-analysis.

Acquired cystic disease-associated renal cell carcinoma (ACD-RCC) is a common subtype of renal cell carcinoma (RCC) in end-stage renal disease (ESRD) patients. The current systematic review and meta-analysis was performed to evaluate the clinicopathological, and genetic characteristics of patients with ACD-RCC. A systematic search on three electronic databases including the Pubmed, Scopus, and Web of Science databases were performed until December 31, 2022.

The Link between Autosomal Dominant Polycystic Kidney Disease and Chromosomal Instability: Exploring the Relationship.

In autosomal dominant polycystic kidney disease (ADPKD) with germline mutations in a or gene, innumerable cysts develop from tubules, and renal function deteriorates. Second-hit somatic mutations and renal tubular epithelial (RTE) cell death are crucial features of cyst initiation and disease progression. Here, we use established RTE lines and primary ADPKD cells with disease-associated mutations to investigate genomic instability and DNA damage responses.

Acquired cystic disease-associated renal cell carcinoma with PTCH1 mutation: a case report.

Acquired cystic disease-associated renal cell carcinoma (ACD-RCC) is an extremely rare kidney tumor seen mainly in patients with end-stage renal disease. Currently, there are few reports on this type of tumor. We describe the case of a 58-year-old man who had been receiving peritoneal dialysis for more than nine years due to chronic renal insufficiency and uremia.

An Artificial Intelligence Generated Automated Algorithm to Measure Total Kidney Volume in ADPKD.

Introduction: Accurate tools to inform individual prognosis in patients with autosomal dominant polycystic kidney disease (ADPKD) are lacking. Here, we report an artificial intelligence (AI)-generated method for routinely measuring total kidney volume (TKV).

Methods: An ensemble U-net algorithm was created using the nnUNet approach.

Actual encounters of the kidney kind: Exploring 48 cases of renal collision tumors through the lens of literature.

Multiple tumors of different lineages merging into a single mass, termed collision tumors, are considered a rare phenomenon in the kidney. Tumor components, or partners, may be malignant (including metastatic disease), borderline, or benign. We report the largest cohort to date of 48 cases.

G Protein Coupled Receptor 87 (GPR87) in End Stage Kidney and Associated Tumors.

Background/aim: End-stage renal disease (ESRD) and acquired cystic renal disease (ACRD) are characterized by progressive inflammation, structural remodeling and by development of unique cancer types. Eosinophilic-vacuolated and chromophobe-like renal cell carcinoma develop exclusively in ACRD kidney. The aim of the study was to investigate the molecular mechanism of ESRD/ACRD carcinogenesis.

Performance and Interpretation of Sonography in the Practice of Nephrology: Core Curriculum 2024.

Ultrasonography is increasingly being performed by clinicians at the point of care, and nephrologists are no exception. This Core Curriculum illustrates how ultrasonography can be incorporated into clinical decision making across the spectrum of kidney disease to optimize the care nephrologists provide to patients. Sonography is valuable in outpatient and inpatient settings for the diagnosis and management of acute and chronic kidney disease, evaluation of cystic disease, urinary obstruction, pain, hematuria, proteinuria, assessment of volume status, and in providing guidance for kidney biopsy.
