This study aims to compare operative time, recurrence, and complications between laparoscopic and open techniques for the repair of inguinal hernia in children. Pubmed and Embase databases were systematically searched for studies of pediatric patients who underwent open or laparoscopic inguinal hernia procedures. The main outcomes were operative time, recurrence, and complications.

Background And Objective: Laryngeal Cancer (LC) constitutes approximately one third of head and neck cancers. Detecting early-stage lesions in this anatomical region is crucial for achieving a high survival rate. However, it poses significant diagnostic challenges owing to the varied appearance of lesions and the need for precise characterization for appropriate clinical management.

Background: Among the alleles of the ABO system, cisAB and B(A) are the most intriguing due to their ability to encode a glycosyltransferase that can synthesize both A and B antigens. This dual activity leads to the formation of the AB phenotype, even in the presence of the O allele; resolution is achieved by molecular analyses.

Case Presentation And Methods: We describe herein a Brazilian family in which the mother (M42.

Background: There is a lack of information from Brazil regarding therapies used and outcomes in patients with acute coronary syndrome with ST elevation (STEMI).

Objectives: To evaluate evidence-based therapies, occurrence of outcomes, reperfusion use, and predictors of not receiving reperfusion in patients with STEMI in a national multicenter registry.

Methods: Patients with STEMI from the ACCEPT registry, with up to 12 hours of symptoms, were followed for 1 year for the occurrence of major adverse cardiovascular events.

Article Synopsis
  • Oxidative stress significantly impacts various diseases, and this study presents a new model using hydrogen peroxide-induced stress in Galleria mellonella larvae as a cost-effective and ethical research alternative.
  • The model serves as a bridge between in vitro and in vivo studies and helps identify important biomarkers related to oxidative stress, including lipid peroxidation and antioxidant enzyme activities.
  • Results indicate that while G. mellonella larvae can tolerate high hydrogen peroxide doses initially, prolonged exposure leads to increased damage and reduced survival due to inadequate antioxidant defenses.
