Objective: To assess the prognosis of patients with hematologic malignancies in acute renal failure who require hemodialysis.
Design: Retrospective study.
Setting: ICU.
Patients: Forty-three consecutive patients.
Methods: Prognostic analysis using both univariate and multivariate (stepwise regression) methods.
Results: Fifteen (35%) patients recovered from acute renal failure and 12 (28%) were discharged from the ICU. The prognosis of patients with acute renal failure linked to sepsis is poorer than the prognosis of the patients with acute renal failure from other etiologies. Only one patient survived in the former group (n = 26) and 11 in the latter group (n = 17); p less than .0001 in multivariate analysis. When accompanied by associated respiratory failure, mortality rate was higher (93% vs. 33%; p less than .0001). The Simplified Acute Physiology Score (SAPS) calculated within the first 24 hr of admission was significantly (p less than .001) related to mortality when the SAPS was greater than or equal to 13. The presence of neutropenia and the type of hematologic malignancy were not related to a worse prognosis. Tolerance to hemodialysis appeared good, and complications were rare.

Association of chronic kidney disease with acute clinical outcomes and hospitalization costs of cancer resection.
PLoS One
January 2025
Cardiovascular Outcomes Research Laboratories (CORELAB), University of California, Los Angeles, Los Angeles, CA, United States of America.
Purpose: Patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD) have been noted to face increased cancer incidence. Yet, the impact of concomitant renal dysfunction on acute outcomes following elective surgery for cancer remains to be elucidated.
Methods: All adult hospitalizations entailing elective resection for lung, esophageal, gastric, pancreatic, hepatic, or colon cancer were identified in the 2016-2020 National Inpatient Sample.
Iodinated Contrast Adsorption in Cartridges With Styrene-Divinylbenzene Sorbent.
Artif Organs
January 2025
International Renal Research Institute of Vicenza (IRRIV), Vicenza, Veneto, Italy.
Background: Contrast-associated acute kidney injury (CA-AKI) is frequent in patients with chronic kidney disease who are submitted to cardiac endovascular procedures using iodinated contrast. In hemoadsorption, cartridges containing styrene-divinylbenzene sorbent resin are applied to remove substances from the blood through an extracorporeal circuit. Importantly, iodinated contrast is also removed via adsorption.

Med Chem
January 2025
Cancer Center, The First Affiliated Hospital of Jinzhou Medical University, Jinzhou, 121001, China.
Background: Dopamine (1) is a commonly used vasopressor, primarily employed to treat various types of shock, congestive heart failure, and acute renal failure. Dopamine dimer (2) is an impurity generated during the production process of dopamine raw materials or the metabolism of dopamine drugs themselves.
Methods: This article presents an effective method for synthesizing dopamine dimer through the condensation of methyl 3,4-dimethoxyphenyl acetate (4) and 3,4-dimethoxyphenylethyl amine (5), followed by reduction and demethylation.
Role of Ciliary Neurotrophic Factor in Angiotensin II-Induced Hypertension.
Hypertension
January 2025
Department of Nephrology, Medical Faculty, University Hospital Düsseldorf, Heinrich Heine University Düsseldorf, Germany (S.A.P., I.Q., D. Arifaj, M.K., D. Argov, L.C.R., J.S.).
Background: Ciliary neurotrophic factor (CNTF), mainly known for its neuroprotective properties, belongs to the IL-6 (interleukin-6) cytokine family. In contrast to IL-6, the effects of CNTF on the vasculature have not been explored. Here, we examined the role of CNTF in AngII (angiotensin II)-induced hypertension.
