Introduction: This study was designed to investigate whether renal α-klotho levels are associated with renal pathology. This is the first report on patients with chronic kidney disease (CKD).
Methods: We conducted a retrospective observational study. A total of 65 CKD patients were enrolled. Serum and renal biopsy samples were collected. Estimated glomerular filtration rate (eGFR) was examined by biochemical test. And α-klotho expressions were assessed by RT-PCR and immunohistochemistry. In addition, detailed microscopic findings were reviewed.
Results: Renal α-klotho levels are associated positively with eGFR, and negatively with renal pathology, including interstitial fibrosis, inflammatory cell infiltration, and tubular atrophy.
Conclusions: The renal α-klotho is related to renal pathology.

Mean arterial pressure at the initiation of continuous renal replacement therapy as a prognostic indicator in patients with acute kidney injury.
Ren Fail

Department of Nephrology, The First Affiliated Hospital of Shenzhen University, Shenzhen Second People's Hospital, Shenzhen, Guangdong Province, China.
Background: Acute kidney injury (AKI) is a common complication in critically ill patients, with approximately 5% requiring continuous renal replacement therapy (CRRT). This study investigated the relationship between mean arterial pressure (MAP) and 28- and 90-day mortality in critically ill AKI patients treated with CRRT.
Methods: This secondary analysis of a bicenter, retrospective, observational study included patients with AKI who were treated with CRRT from January 2009 to September 2016.

Background: McKittrick-Wheelock syndrome is an uncommon and severe disorder caused by large hypersecretory tumors located in the distal colorectal area. Excessive secretion from adenomas is an unusual clinical manifestation that leads to severe electrolyte and fluid depletion, subsequently resulting in kidney injury. Successful treatment relies on quick and cooperative decision-making for timely intervention.

Background: Kidney transplantation is the ultimate treatment for end-stage kidney disease. Function of the kidney graft is not only dependent on medical factors but also on a complication-free surgical procedure. In the event of major surgical complications, the kidney graft is potentially lost and the patient will return to the waiting list which may be long.

Department of Veterinary Sciences, Veterinary Teaching Hospital "Mario Modenato", University of Pisa, via Livornese snc, San Piero a Grado, Pisa, Italy.
Background: Current endogenous indicators utilised in avian medicine are not sensitive enough to detect renal disease in its early stages. Alternative markers ought to be examined as a result. The aim is to investigate the accuracy of limited-sampling models for glomerular filtration rate (GFR) in adult seagulls using plasma clearance of iohexol (IOX).

Background: Infectious episodes contribute to morbidity and mortality in patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Renal involvement, also known as ANCA-associated glomerulonephritis (AGN), is frequently observed in AAV. Little is known about whether co-infection at initial diagnosis is associated with renal outcome and prognosis in children with AGN.
