Background: Therapeutic plasma exchange (TPE) has evolved to an accepted therapy for selected indications. However, it is technically challenging in children. Moreover, data on safety and efficacy are mainly derived from adult series. The aim of this study was to review the procedure in the context of clinical indications, effectiveness, and safety.
Study Design And Methods: All TPE procedures performed at a tertiary care hospital during a 12-year period (2005-2016) were retrospectively evaluated.
Results: Eighteen patients with a median age of 8.5 (0.2-17) years underwent a total of 280 TPE sessions. Eleven (61%) patients were treated for renal diseases. Three (17%) patients were diagnosed with neurological diseases, two had liver failure, and one patient each had sepsis and stem cell transplant-associated thrombotic microangiopathy. Seven patients (39%) were classified as American Society for Apheresis Category I, four (22%) as Category II, two (13%) each as Category III and IV, and two (13%) were not classified. Two patients with atypical hemolytic-uremic syndrome received TPE as long-term therapy over 2 and 5 years. All procedures were performed using the filtration technique and heparin anticoagulation. Twelve (67%) patients showed full or partial recovery after TPE, six had no response or an uncertain response. Minor adverse events occurred in 30/280 (10.6%) procedures, and one major complication (0.4%) was reported.
Conclusion: TPE is a safe apheresis method in children, even when performed as a long-term therapy. Efficacy is high under selected conditions. A highly skilled and experienced staff is mandatory to ensure patient safety and efficacy.

MicroRNAs (miRNAs) are associated with amyloid-β (Aβ) dysmetabolism, a pivotal factor in the pathogenesis of Alzheimer's disease (AD). This study unveiled a novel miRNA, microRNA-32533 (miR-32533), featuring a distinctive base sequence identified through RNA sequencing of the APPswe/PSEN1dE9 (APP/PS1) mouse brain. Its role and underlying mechanisms were subsequently explored.

Interest in preventative dietary interventions for human health has increasingly focused on the endocannabinoid (eCB)-like compound palmitoylethanolamide (PEA), a bioactive lipid mediator with anti-inflammatory, analgesic, and neuroprotective properties. This Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020-compliant systematic review aimed at collecting and comprehensively discussing all available data from Randomized Controlled Trials (RCTs) evaluating the efficacy and tolerability of PEA supplementation across human illnesses in patient populations. Overall, 48 eligible outputs from 47 RCTs were extracted, covering neuropsychiatric ( = 15), neurological ( = 17), somatic ( = 13), and visceral ( = 11) disturbances, as well as PEA effects on blood/plasma or other tissue biomarkers ( = 10).

Background: Type II diabetes mellitus (T2DM) has been associated with increased risk of colon cancer (CC) and worse prognosis in patients with metastases. The effects of T2DM on postoperative chemoresistance rate (CRR) and long-term disease-free survival (DFS) and overall survival (OS) in patients with stage III CC who receive curative resection remain controversial.
Aim: To investigate whether T2DM or glycemic control is associated with worse postoperative survival outcomes in stage III CC.

The harmful by-product of paracetamol is known as N-Acetyl-p-benzoquinoneimine, (NAPQI). When paracetamol is given at therapeutic dosages or in excess, it undergoes Phase I metabolism in the liver via Cytochrome P-450 2E1 (CYP2E1), and then it produces NAPQI. Previous studies reported that a non-ionic surfactant known as Brij 35 (Polyoxyethylene lauryl ether) has been shown to be an effective inhibitor of CYP2E1 and P-glycoprotein (P-gp).
