Identifying Key Biomarkers in Pediatric Pulmonary Hypertension: An Investigative Approach.

This study assesses the utility of early biomarkers-5-hydroxyindoleacetic acid (5-HIAA) and insulin-like growth factor 1 (IGF-1)-for diagnosing and monitoring pulmonary hypertension (PH) in children with congenital heart defects (CHD). Due to the risks associated with invasive diagnostics, such as right heart catheterization, non-invasive biomarkers provide a safer alternative for early PH detection. This cohort-based study utilized blood and urine samples to measure 5-HIAA and IGF-1 levels via enzyme immunoassays.

Genetic Predictors of the Development of Complications after Coronary Stenting.

Due to the fact that there are scientific discussions about the significance of gene polymorphisms in the risk of developing cardiovascular complications after a percutaneous coronary intervention, it is of interest to evaluate the genetic predictors of the development of cardiovascular events. This study is a molecular genetic study. Association with the genes of biomarkers for inflammation and immune response increases the risk of cardiovascular events: rs1234313 (TNFSF4): (A/G, OR-4.

Mortality Risk Factors of Early Neonatal Sepsis During COVID-19 Pandemic.

Purpose: This study aimed to determine predisposing factors for negative outcome in infants with early neonatal sepsis during COVID-19.

Patients And Methods: A prospective cohort study of 172 newborns up to 4 days diagnosed with neonatal sepsis was carried out in Karaganda (Kazakhstan). The microbiological examination was used to identify a causative agent of bloodstream infection.

The Presence of PDL-1 on CD8+ Lymphocytes Is Linked to Survival in Neonatal Sepsis.

Sepsis is life-threatening organ dysfunction caused by a dysregulated host response to infection. Neonatal sepsis is the main cause of death in newborns, especially preterm infants. The pathogenesis of sepsis is based on a hyper-inflammatory syndrome combined with an immunosuppressive mechanism in sepsis.

Influence of Pathogen Type on Neonatal Sepsis Biomarkers.

Understanding immunoregulation in newborns can help to determine the pathophysiology of neonatal sepsis and will contribute to improve the diagnosis, prognosis, and treatment and remains an urgent and unmet medical need to understand hyperinflammation or hypoinflammation associated with sepsis in newborns. This study included infants (up to 4 days old). The "sepsis" criteria was a positive blood culture.

Proinflammatory cytokines and colorectal cancer - the impact of the stage.

Colorectal cancer is one of the most often diagnosed malignant tumors. In Kazakhstan, high incidence of CC is registered along with other oncology diseases. Despite a significant progress in the disease treatment achieved lately, CC is still one of the major reasons of mortality due to oncologic pathologies.
