Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. Due to new therapeutic schedules and cooperation between oncological centers it is curable in more than 80% of affected children. For the optimalization of the therapy there is necessary to assess the risk criteria that have influence on the treatment results in the certain groups of patients. Hyperleukocytosis and the age (less than 1 year and more than 10 years) are known as unfavorable risk factors. The study was designed to assess the long-term treatment results in children with ALL and the initial leukocytosis over 50 000/mm3 with the use of the modified "New York" protocols. We present the treatment results of 340 children with ALL treated in nine centers of Polish Pediatric Leukemia/Lymphoma Study Group (PPLLSG) according to three consecutive versions of modified "New York" protocol (group I, II, and III) between 1987 and 2003. Within the analyzed groups the first complete remission (I CR) was achieved in 91%, 95% and 96% of the patients, respectively. Relapses occurred in 37%, 21.5% and 26% of the patients and 3.7%, 1.8% and 5.7% of children died in the I CR due to complications, in the I, II and III therapeutic group, respectively. Obtained 5-and 10-year event-free survival (EFS) were 56% and 53.5% for the group I and 73% and 73% for the group II. Five-year EFS for the group III was 67%. The implementation of the New York protocol in 1987 and New York I in 1997 has improved the treatment results in children with ALL and initial leukocytosis over 50 000/mm3. Protocol New York II did not further improve the treatment results. Among analyzed parameters (age, gender, the initial leukocytosis, the blast cells immunophenotype) only age had the statistical significance. The implementation of modified "New York" protocols has improved the treatment results in children with ALL and initial leukocytosis over 50 000/mm3 compared to previous results.

Immune checkpoint inhibitors (ICIs) have transformed cancer treatment but are frequently associated with immune-related adverse events (irAEs). This article offers a novel synthesis of findings from both preclinical and clinical studies, focusing on the molecular mechanisms driving irAEs across diverse organ systems. It examines key immune cells, such as T cell subsets and myeloid cells, which are instrumental in irAE pathogenesis, alongside an in-depth analysis of cytokine signaling [interleukin (IL)-6, IL-17, IL-4), interferon γ (IFN-γ), IL-1β, tumor necrosis factor α (TNF-α)], integrin-mediated interactions [integrin subunits αITGA)4 and ITGB7], and microbiome-related factors that contribute to irAE pathology.

Pancreatic cancer, especially pancreatic ductal adenocarcinoma (PDAC), is one of the most challenging clinical conditions due to its late-stage diagnosis and poor survival rates. Mesenchymal stem cells (MSCs), used for targeted therapies, are being explored as a promising treatment because of their tumor-homing properties and potential contributions to the pancreatic cancer microenvironment. Understanding these interactions is crucial for developing effective treatments.

The manufacturing of soy-based adhesives with high bonding strength, excellent water resistance, and exceptional environmental performance still faces difficulties. In this work, using glyoxal-urea (GU) resin, chitosan (CS), and soy protein isolate (SPI) as the primary raw materials in order to effectively mitigate the release of free formaldehyde commonly found in traditional wood-based panels. Obtaining an adhesive with high strength, excellent water resistance, and a stable cross-linking structure of GU/CS/SPI (CS represents different mass fractions of chitosan solution).

This study presents a new approach for fabricating 3D-printed self-healing hydrogels via light-assisted 3D printing, utilizing Schiff-base and covalent bonding formations resulting from the reaction between amine and aldehyde functional groups alongside the photopolymerization of methacrylate groups. Two distinct polymers, carboxymethyl chitosan (CMCs) and dextran, were first modified to yield methacrylate-modified carboxymethyl chitosan (CMCs-MA) and oxidized dextran (OD). The structural modifications of these polymers were confirmed using spectroscopic techniques, including H NMR and FTIR analyses.
