BACKGROUND: Epigastric pain is frequent in Emergency Medicine and remains a challenging situation. Besides benign etiologies such as gastritis or uncomplicated cholelithiasis, it could reveal myocardial infarction or vascular disease. Point-of-care ultrasound (POCUS) could be performed in such situation. CASE PRESENTATION: A healthy 66-year-old man with no previous medical history was admitted to the Emergency Department for a rapid onset epigastric pain. He reported taking non-steroidal anti-inflammatories for 1 week prior to admission...

Background: Precise regional quantitative assessment of renal function is limited with conventional 99mTc-labeled renal radiotracers. A recent study reported that the positron emission tomography (PET) radiotracer 2-deoxy-2-18F-fluorosorbitol (18F-FDS) has ideal pharmacokinetics for functional renal imaging. Furthermore, 18F-FDS is available via simple reduction from routinely used 2-deoxy-2-18F-fluoro-D-glucose (18F-FDG). We aimed to further investigate the potential of 18F-FDS PET as a functional renal imaging agent using rat models of kidney diseases...

A major reason for poor long-term kidney transplant outcomes is the development of chronic allograft injury, characterized by interstitial fibrosis and tubular atrophy. Currently, an invasive biopsy that samples only <1% of the kidney is the gold standard for detecting kidney allograft fibrosis. We report the use of magnetic resonance elastography (MRE) to quantify tissue stiffness as a noninvasive and whole-kidney measurement tool of allograft fibrosis in a kidney transplant patient at 2 time points. The MRE whole-kidney stiffness values reflected the changes in fibrosis of the kidney allograft as assessed by histologic examination...

BACKGROUND: Mild hyperphosphatemia is a putative risk factor for cardiovascular disease [CVD], loss of kidney function, and mortality. Very limited data are available from sizable multicenter kidney transplant recipient (KTR) cohorts assessing the potential relationships between serum phosphorus levels and the development of CVD outcomes, transplant failure, or all-cause mortality. STUDY DESIGN: Cohort study. SETTING & PARTICIPANTS: The Folic Acid for Vascular Outcome Reduction in Transplantation (FAVORIT) Trial, a large, multicenter, multiethnic, controlled clinical trial that provided definitive evidence that high-dose vitamin B-based lowering of plasma homocysteine levels did not reduce CVD events, transplant failure, or total mortality in stable KTRs...

Critically ill patients with acute kidney injury (AKI) are heterogeneous on pathophysiology and prognosis. The role of endothelial damage in the pathogenesis of refractory AKI has not been clarified. The aim was to determine if biomarkers of endothelial damage, independently of the inflammatory insult on the kidney, can predict recovery of acute kidney injury. METHODS: From the "Procalcitonin And Survival Study" multicenter intensive care unit cohort, followed for 28 days after admission, we included patients without chronic kidney disease, who survived >24 h after admission and with plasma samples at admission available for biomarker analysis...

Blood is a bodily fluid that is vital for a number of life functions in animals. To a first approximation, blood is a mildly alkaline aqueous fluid (plasma) in which a large number of free-floating red cells (erythrocytes), white cells (leucocytes), and platelets are suspended. The primary function of blood is to transport oxygen from the lungs to all the cells of the body and move carbon dioxide in the return direction after it is produced by the cells' metabolism. Blood also carries nutrients to the cells and brings waste products to the liver and kidneys...

BACKGROUND: Frail individuals are at increased risk for poor outcomes, including adverse drug events. Kidney function is often compromised in frailty and is a key consideration in medication choice and dosing; however, creatinine-based measures of kidney function may be biased in frail individuals. STUDY DESIGN: Observational study. SETTING & PARTICIPANTS: 4,987 community-dwelling older men and women with complete data who participated in visit 5 of the Atherosclerosis Risk in Communities (ARIC) Study (2011-2013)...

BACKGROUND: The measurement of urinary biomarkers during ex vivo normothermic kidney perfusion (EVKP) may aid in the assessment of a kidney prior to transplantation. This study measured levels of neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1) and endothelin-1 (ET-1) during EVKP in a series of discarded human kidneys. METHODS: Fifty-six kidneys from deceased donors were recruited into the study. Each kidney underwent 60 minutes of EVKP and was scored based on the macroscopic appearance, renal blood flow and urine output...

BACKGROUND: Natural honey (honey) is considered as a part of traditional medicine all over the world. It has both antimicrobial and antioxidant properties, useful in stimulation of wounds and burns healing and gastric ulcers treatment. The aim of this study, for the first time, was to investigate the antioxidant properties and protective role of honey against carcinogen chemical aflatoxin (AF) exposure in rats, which were evaluated by histopathological changes in liver and kidney, measuring level of serum marker enzymes [aspartate aminotransferase (AST), alanin aminotransferase (ALT), gamma glutamil transpeptidase (GGT)], antioxidant defense systems [Reduced glutathione (GSH), glutathione reductase (GR), superoxide dismutase (SOD), glutathione-S-transferase (GST) and catalase (CAT)], and lipid peroxidation content in liver, erythrocyte, brain, kidney, heart and lungs...

We report a case of a 20-year-old female having systemic hypertension who presented with right-sided proptosis, chemosis, and diminished vision, preceded by an acute episode of unilateral throbbing headache. Imaging studies revealed a right-sided direct, spontaneous carotid-cavernous fistula (CCF), aneurysm of internal carotid artery, bleed in the parieto-frontal lobe, and swelling of extraocular muscles. Abdominal ultrasound revealed a small contracted right kidney measuring 64 mm × 27 mm. A direct spontaneous CCF can occur spontaneously following rupture of intracranial aneurysm without any history of trauma or connective tissue disorder...
