Abstract Background Ventilator‐associated pneumonia (VAP) is a frequent and severe complication among newborns in neonatal intensive care units (NICUs). It associated with elevated morbidity mortality rates, more extended hospital stays increased health costs. Implementing preventive bundles structured sets of evidence‐based practices reduces VAP incidence. As primary caregivers, nurses are critical consistently applying these measures NICU settings. Aim To evaluate the impact training...

Abstract Background Immune thrombocytopenia (ITP) is characterized by immune response dysregulations. Cytotoxic T lymphocyte‐associated antigen‐4 (CTLA‐4) plays a central role in checkpoint pathways and preventing autoimmune diseases regulating tolerance. We aimed to explore the potential association between CTLA-4 gene polymorphisms ITP as well study their impact on therapy. Methods investigated two single‐nucleotide (SNPs; rs: 231775 3087243) using real-time PCR plasma levels of ELISA 88...

Atherosclerosis has been extensively studied in thalassemia major (TM) and sickle cell disease but not yet β intermedia (TI). Previous studies concerned with TM were performed children. TI patients usually live longer and, thus, are more prone to complications of atherosclerosis.In our study, we applied color Doppler for the determination arterial conduit flow velocities patients.For central circulation, measured right left middle cerebral arteries (MCAs) basilar artery (BA) mean velocity...

Acute myeloid leukemia (AML) is a potentially fatal hematological disease. Along with disease-related factors, patient-related in particular age, are strong predictor of outcome that influence treatment decisions. Many acute risk stratification models have been developed to predict the intensive chemotherapy. However, these did not include physical function assessments.This study investigated impact several namely performance status, and age on short-term outcomes chemotherapy cohort 50...
