Renal replacement therapies (RRT) are increasingly used for the treatment of acute and chronic kidney diseases as well as intoxications and accidental drug overdoses. These therapies offer a mechanism for the removal of toxic substances from the patient's blood and supplement the standard detoxification protocols. If instituted early, RRT can have a significant effect on the course of the toxicity; however, this process is not selective for the removal of only harmful products and can also result in the clearance of medications intended for therapeutic use.

Impact of hemoadsorption with CytoSorb® on meropenem and piperacillin exposure in critically ill patients in a post-CKRT setup: a single-center, retrospective data analysis.
Intensive Care Med Exp

Purpose: CytoSorb® (CS) adsorbent is a hemoadsorption filter for extracorporeal blood purification often integrated into continuous kidney replacement therapy (CKRT). It is primarily used in critically ill patients with sepsis and related conditions, including cytokine storms and systemic inflammatory responses. Up to now, there is no evidence nor recommendation for the use of CS filters in sepsis (22).

Circulating histones have been identified as essential mediators that lead to hyperinflammation, platelet aggregation, coagulation cascade activation, endothelial cell injury, multiple organ dysfunction, and death in severe patients with sepsis, multiple trauma, COVID-19, acute liver failure, and pancreatitis. Clinical evidence suggests that plasma levels of circulating histones are positively associated with disease severity and survival in patients with such critical diseases. However, safe and efficient therapeutic strategies targeting circulating histones are lacking in current clinical practice.

Aim: To evaluate the efficacy of flexible ureteroscopic lithotripsy (FURL) and extracorporeal shock wave lithotripsy (ESWL) in the treatment of ureteral calculi based on decision tree model.
Methods: A total of 600 patients with ureteral calculi, including 289 treated with FURL and 311 cases with ESWL in Anqing Municipal Hospital from June 2021 to August 2023, were selected as study subjects. Perioperative indicators and stone clearance rate of the two groups were compared, and the preoperative and postoperative (24 and 72 hours) changes of serum creatinine, cystatin C (Cys-C) and microalbumin were observed.
Redo mitral valve replacement with annular reconstruction of left atrial dissection following mitral valve replacement for infective endocarditis: a case report.

Department of Cardiovascular Surgery, Osaka General Medical Center, Osaka, 558-8558, Japan.
Background: Left atrial dissection is a rare and occasionally fatal complication of cardiac surgery and is defined as the creation of a false chamber through a tear in the mitral valve annulus extending into the left atrial wall. Some patients are asymptomatic, while others present with various symptoms, such as chest pain, dyspnea, and even cardiac arrest. Although there is no established management for left atrial dissection, surgery should be considered in patients with hemodynamic disruption.

While traditional ECMO systems are effective, their large priming volumes and significant blood-contacting surface areas can lead to complications, particularly in neonates and pediatric patients. Microfluidic ECMO systems offer a promising alternative by miniaturizing the ECMO technology, reducing blood volume requirements, and minimizing device surface area to improve safety and efficiency.
