Perioperative Hyper-coagulation and Thrombosis: Cost Analysis After Congenital Heart Surgery.

Thrombosis, a major adverse event of congenital heart surgery, has been associated with poor outcomes. We hypothesized that in CHD patients undergoing cardiac surgery, increased perioperative use of pro-coagulant products may be associated with postoperative thrombosis in the setting of hyperfibrinogenemia, leading to greater hospital and blood product costs. Single-center retrospective study.

Impact of dual neutralization of TNF-α and IL-1β along with Gentamicin treatment on the functions of blood and splenic neutrophils and its role on improvement of S. aureus induced septic arthritis.

Researches of recent past years have emphasized potential of antibiotics to improve septic arthritis but as multi-drug resistant strains like MRSA are emerging fast, new alternative therapeutic advances are high in demand. This study aims to figure out the role of neutrophils in regulating inflammatory responses of S. aureus induced septic arthritis while using TNF-α Ab or IL-1β Ab along with antibiotic gentamicin or both in combination.

Pyrrolidine dithiocarbamate in combination with L-N-monomethyl arginine alleviates Staphylococcus aureus infection via regulation of CXCL8/CXCR1 axis in peritoneal macrophages in vitro.

The CXCL8/CXCR1 axis in conjoint with the free radicals and anti-oxidants dictates the severity of inflammation caused by the bacteria, Staphylococcus aureus. S.aureus mediated inflammatory processes is regulated by NF-κB and its product, iNOS.

IL-10 in combination with IL-12 and TNF-α attenuates CXCL8/CXCR1 axis in peritoneal macrophages of mice infected with Staphylococcus aureus through the TNFR1-IL-1R-NF-κB pathway.

Overexpression of Staphylococcus aureus mediated CXCL8/CXCR1 axis is a major cause of sepsis and severe inflammatory diseases. This chemokine acts conjointly with various pro-inflammatory and anti-inflammatory cytokines that govern the severity of inflammation. The effects of different combinations of exogenous cytokines on CXCR1 expression in macrophages remain undetermined.

Comparison of Thromboelastography Devices TEG6S Point of Care Device vs. TEG5000 in Pediatric Patients Undergoing Cardiac Surgery.

Thromboelastography (TEG) can predict bleeding in pediatric patients undergoing cardiac surgery. We hypothesized that results obtained from TEG5000 correlate with the new point-of-care TEG6S system and that TEG6S rewarming maximum amplitude (MA) is associated with surrogate endpoints for perioperative bleeding in pediatric patients who underwent complex cardiac surgery. We describe a retrospective study of pediatric (≤18 years) patients who underwent complex cardiac surgery on cardiopulmonary bypass.

Implications of Transfusion in Adults with Congenital Heart Disease Undergoing Cardiac Surgery.

The number of adults with congenital heart disease (CHD) requiring cardiovascular (CV) surgery is increasing rapidly in today's era. We hypothesized that exposure to perioperative blood products is associated with worse outcomes in adults. All adults (≥ 18 years old) undergoing CV surgery with Cardio-Pulmonary Bypass (CPB) between 2015 and 2020 were reviewed retrospectively.

Clinical implications of acute shunt thrombosis in paediatric patients with systemic-to-pulmonary shunt re-interventions.

Purpose: Systemic-to-pulmonary shunts are used as a source of pulmonary blood flow in palliated Congenital Heart Disease in neonates and young infants. Shunt thrombosis, often requiring shunt interventions during index hospitalisation, is associated with poor outcomes. We hypothesised that extensive use of perioperative pro-coagulant products may be associated with shunt thrombosis.

Expert opinion on the preoperative medical optimization of adults with diabetes undergoing metabolic surgery.

Diabetes mellitus (DM) and obesity are interrelated in a complex manner, and their coexistence predisposes patients to a plethora of medical problems. Metabolic surgery has evolved as a promising therapeutic option for both conditions. It is recommended that patients, particularly those of Asian origin, maintain a lower body mass index threshold in the presence of uncontrolled DM.

Calciphylaxis-Associated Cutaneous Vascular Calcification in Noncalciphylaxis Patients.

Calciphylaxis is a highly morbid disease that is strongly associated with chronic kidney disease (CKD); however, the histologic criteria for diagnosis have not been well established nor have their specificity for calciphylaxis been determined. This retrospective study aimed to examine the prevalence of histologic features commonly associated with calciphylaxis in noncalciphylaxis patients. We also sought to evaluate whether these features may be more prevalent in patients with CKD.

Neutralization of TNF-α and IL-1β Regulates CXCL8 Production through CXCL8/CXCR1 Axis in Macrophages during Infection.

Anti-cytokine therapy is widely acknowledged as an anti-inflammatory technique to treat varied infectious diseases. TNF-α and IL-1β are major cytokines that regulate every aspect of the inflammatory process. However, the effects of single or dual cytokine neutralization on mediated CXCL8 secretion and CXCR1 expression in murine peritoneal macrophages remained noninvestigated.

Regulation of Staphylococcus aureus-induced CXCR1 expression via inhibition of receptor mobilization and receptor shedding during dual receptor (TNFR1 and IL-1R) neutralization.

Our earlier studies proposed a radically new idea suggesting interdependency between TNF-α/TNFR1 and IL-1β/IL-1R pathways in modulation of Staphylococcus aureus-induced CXCL8/CXCR1 axis. However, the effects of inhibition of cytokine receptor mobilization at intracellular level and surface TNFR1 and IL-1R shedding on S. aureus-induced CXCR1 expression have not been studied so far in peritoneal macrophages.
