46 patients underwent mitral valve repair at the Regional Hospital in Trondheim/St. Elisabeth Heart Clinic, during the period 1983-95. There were 20 female patients. The valve pathology was ischemic in 40%, rheumatic in 10% and other or unknown in 50%. The surgical technique included commissurotomy (n = 9), ring annuloplasty (n = 18), resection of posterior leaflet (n = 12), Kay annuloplasty (n = 10), shortening of chordae (n = 3) and other techniques (n = 2). Postoperative complications included wound infection (n = 1), pneumonia (n = 1), mediastinitis (n = 1), pleural effusion (n = 5), renal failure (n = 1) and multi-organ failure (n = 1). One patient required re-exploration for postoperative bleeding. Three (6.5%) patients died within 30 days of surgery due to low cardiac output (n = 2) and multi-organ failure (n = 1). Nine patients (21%) died later. At follow up, within one year of surgery, marked functional improvement was registered, with only one patient in NYHA class III and none in class IV.

Objective: Frailty has become an increasingly recognized perioperative risk stratification tool. While frailty has been strongly correlated with worsening surgical outcomes, the individual determinants of frailty have rarely been investigated in the setting of aortic disease. The aim of this study was to examine the determinants of an 11-factor modified frailty index (mFI-11) on mortality and postoperative complications in patients undergoing endovascular aortic aneurysm repair (EVAR).

In critically ill patients, compromised microcirculation causes tissue hypoxia, organ failure, and death. These pathophysiological processes occur particularly in patients with high illness severity, so reliable hypoxia biomarkers should reflect this in their occurrence. This secondary analysis of a prospective study categorized patients by their burden of organ dysfunction (BOD) using the cohort's median initial sequential organ failure assessment (SOFA) score of 8 as a cutoff.

: The bite of the Loxosceles spider is a public health problem around the world, mainly in Latin America. The viscerocutaneous presentation is related to the inoculation of toxins (phospholipase-D) that generates a systemic inflammatory reaction with a subsequent increase in cytokines and chemokines. Hemoadsorption is proposed as a therapy that allows for the removal of the toxin and modulation of the inflammatory response in this disease.

Acute pancreatitis (AP) is a potentially fatal acute digestive disease that is widespread globally. Although significant progress has been made in the previous decade, the study of mechanisms and therapeutic strategies is still far from being completed. Xanthine oxidase (XO) is an enzyme that catalyzes hypoxanthine and xanthine to produce urate and is accompanied by the generation of reactive oxygen species (ROS) in purine catabolism.

Sepsis is a life-threatening condition resulting from pathogen infection and characterized by organ dysfunction. Programmed cell death (PCD) during sepsis has been associated with the development of multiple organ dysfunction syndrome (MODS), impacting various physiological systems including respiratory, cardiovascular, renal, neurological, hematological, hepatic, and intestinal systems. It is well-established that pathogen infections lead to immune dysregulation, which subsequently contributes to MODS in sepsis.
