Article Abstract
ObjectiveThis study aimed to investigate the prognostic value of the preoperative Inflammatory Prognostic Index (IPI) in predicting late mortality in patients undergoing isolated surgical aortic valve replacement (AVR).MethodsA retrospective, single-center cohort of 400 patients who underwent elective, isolated surgical AVR between 2015 and 2023 was analyzed. The IPI was calculated using the formula: C-reactive protein (CRP) × neutrophil-to-lymphocyte ratio (NLR) / albumin. Patients were stratified into low- and high-IPI groups based on an optimal cut-off value of 0.2588 determined via ROC analysis. Clinical characteristics, operative data, and outcomes were compared. Cox proportional hazards regression was used to identify independent predictors of late mortality.ResultsPatients with high IPI scores (≥0.2588) had significantly increased late mortality compared to those with low IPI (<0.2588) (10.3% vs 2.3%, < .001). High IPI was associated with elevated CRP and neutrophils, and reduced albumin and lymphocytes. In univariate analysis, age, bioprosthesis use, and high IPI were significantly associated with late mortality. However, in multivariate analysis, only high IPI remained an independent predictor (HR = 3.405, 95% CI: 1.289-8.996, = .013). Kaplan-Meier survival analysis confirmed lower long-term survival in the high-IPI group ( < .001).ConclusionPreoperative IPI is a simple, accessible, and independent predictor of late mortality after surgical AVR. Integrating IPI into preoperative risk assessment may improve long-term prognostic stratification and guide perioperative management.

Background: Colorectal cancer (CRC) remains one of the leading causes of cancer-related mortality worldwide. The tumor microenvironment (TME), particularly the interactions between endothelial cells and cancer-associated fibroblasts (CAFs), plays a pivotal role in promoting tumor growth, angiogenesis, oxidative stress, and therapy resistance. The HUVEC-fibroblast co-culture model closely mimics stromal-endothelial interactions observed in CRC, enabling mechanistic insights not achievable in monocultures.

Background: The paper addresses an important section of pediatric combustiology - generalized meningococcal infection, associated with a severe course, the risk of disabling complications, life-threatening conditions, and high mortality.
Objective: The purpose of the study was to share the experience of treating patients with the sequelae of generalized bacterial infection caused by in a children's burn center.
Material And Methods: We conducted a retrospective analysis of the medical records of 23 patients treated in the burn department for babies from 0 to 3 years of the Children's City Clinical Hospital No.

Background MRI-derived arrhythmogenic substrate, including late gadolinium enhancement (LGE) and extracellular volume fraction (ECV), is indicative of sudden cardiac death (SCD) risk in nonischemic dilated cardiomyopathy (DCM). The relative prognostic value of LGE and ECV remains unclear. Purpose To evaluate the performance of LGE and T1 mapping in predicting SCD in patients with DCM and to explore clinical implementation.

Background: Meconium aspiration syndrome (MAS), a common cause of respiratory failure in late preterm and term neonates, is associated with a high risk of mortality and morbidity. Amongst all the treatment modalities for severe MAS, surfactant administration has a proven role in decreasing progressive respiratory failure.
Methods: The present open-label randomised controlled trial aimed to determine the effect of early (≤ 2 h) bolus surfactant therapy as compared to standard care on the total duration of respiratory support.

Objective: To wean respiratory support, preterm infants with severe respiratory failure are often administered systemic corticosteroids. We sought to evaluate if postnatal age or clinical characteristics predicted death or tracheostomy following systemic dexamethasone in evolving bronchopulmonary dysplasia.
Study Design: We performed a retrospective study of infants born at ≤ 30 weeks' gestational age cared for at a Level IV referral center from 2009 to 2019 who received a complete course of systemic dexamethasone beyond 4 weeks of age for the indication of preventing death and/or liberating from positive pressure ventilation.
