A patient with end-stage renal disease on maintenance hemodialysis developed sudden severe abdominal pain and distension. He suffered a decline in his hematocrit and subsequent abdominal imaging revealed a large left-sided retroperitoneal hemorrhage in the setting of atrophic, severely cystic kidneys. He underwent selective left renal artery angiography and embolization due to continued hemorrhage with stabilization in his condition. However, he became paraparetic within hours of the embolization procedure due to spinal cord infarct. Acquired cystic kidney disease is a very common entity in patients with chronic kidney disease. Complications include cystic hemorrhage or infection, erythrocytosis, and renal cell carcinoma. Screening of patients for cystic disease and malignant transformation remains a controversial topic; however, most advocate abdominal imaging after 3 to 5 years on dialysis.

In clinical optical molecular imaging, the need for real-time high frame rates and low excitation doses to ensure patient safety inherently increases susceptibility to detection noise. Faced with the challenge of image degradation caused by severe noise, image denoising is essential for mitigating the trade-off between acquisition cost and image quality. However, prevailing deep learning methods exhibit uncontrollable and suboptimal performance with limited interpretability, primarily due to neglecting underlying physical model and frequency information.

Quantitative Assessment of the Effect of Chronic Kidney Disease on Plasma P-Tau217 Concentrations.
Neurology

Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN.
Background And Objectives: Chronic kidney disease (CKD) is known to be associated with increased plasma phosphorylated tau217 (p-tau217) concentrations, potentially confounding the utility of plasma p-tau217 measurements as a marker of amyloid pathology in individuals with suspected Alzheimer disease (AD). In this study, we quantitatively investigate the relationship of plasma p-tau217 concentrations vs estimated glomerular filtration rate (eGFR) in individuals with CKD with and without amyloid pathology.
Methods: This was a retrospective examination of data from 2 observational cohorts from either the Mayo Clinic Study of Aging or the Alzheimer's Disease Research Center cohorts.

Background: Nirmatrelvir with ritonavir (Paxlovid) is indicated for patients with Coronavirus Disease 2019 (COVID-19) who are at risk for progression to severe disease due to the presence of one or more risk factors. Millions of treatment courses have been prescribed in the United States alone. Paxlovid was highly effective at preventing hospitalization and death in clinical trials.

Background: Prostate cancer remains the most frequent cancer among men, representing a significant health burden. Despite its high morbidity and mortality rates, the etiology of prostate cancer remains relatively unknown, with only non-modifiable established risk factors. Chronic inflammation has emerged as a potential factor in prostate carcinogenesis.
