A Multicenter ICET-A Survey on Adherence to Annual Oral Glucose Tolerance Test (OGTT) Screening in Transfusion-Dependent Thalassemia (TDT) Patients - The Expert Clinicians' Opinion on Factors Influencing the Adherence and on Alternative Strategies for Adherence Optimization.

Background: Current guidelines for screening glucose dysregulation (GD) in patients with transfusion-dependent thalassemia (TDT) recommend an annual 2-hour oral glucose tolerance test (OGTT) starting at the age of 10 years.

Objective: Assessment of adherence to OGTT screening in patients with TDT.

Methods: A questionnaire was distributed to 18 Thalassemia Centers in 10 different countries, targeting factors influencing adherence to annual OGTT screening in specialized multidisciplinary pediatric and adult TDT units and identifying strategies to improve adherence to OGTT in TDT patients.

RAD51 and RAD50 genetic polymorphisms from homologous recombination repair pathway are associated with disease outcomes and organ toxicities in AML.

Background: Acute myeloid leukemia (AML) is a heterogeneous malignancy that responds to various therapies. The sensitivity of leukemia cells to chemotherapy is affected by the DNA damage response (DDR). In this study, we examined the association between RAD51 rs1801320, XRCC3 rs861539, NBS1 rs1805794, MRE11 rs569143, and RAD50 rs2299014 variants of the homologous recombination repair (HRR) pathway and AML outcomes.

ATP-Binding Cassette Transporter Genes and microRNAs in Pediatric B-Cell ALL: Expression Insights.

Background: Acute lymphocytic leukemia (ALL), characterized by uncontrolled growth of abnormal lymphocytes, predominantly affects children. Genetic analysis focusing on genes and microRNAs reveals important information about the biology of ALL, enabling accurate diagnosis and treatment. This study examines gene and microRNA expression in B cell ALL to improve early diagnosis and personalized treatment.

Clinical Outcomes of Pediatric Cancer Patients with COVID-19: A Cross-Sectional Study.

Considering the widespread COVID-19 pandemic and its impact, especially on children, particularly those with cancer, in terms of transmission risk, mortality, and the occurrence of the disease based on various studies in different countries, we decided to conduct this study to improve the care of children with cancer regarding COVID-19. A descriptive cross-sectional study with a confirmed diagnosis of COVID-19 consisted of obtaining 20 mL of blood samples from the participants in a random manner. Diagnostic examinations, including CT scans, chest X-rays, and a range of hematologic and blood tests, such as complete blood count, ESR, CRP, and D-Dimer, were performed on all patients.

Identification of miR-20a as A Potential Discerning Biomarker for Non-Invasive versus Invasive Retinoblastoma.

Objective: Intraocular retinoblastoma (RB) is common in kids. Although the cause of this disease is a mutation in the RB1 gene, the formed cancerous mass in different patients is seen in non-invasive states, limited to the ocular cavity or in invasive states distributed to other parts of the body. Because this tumor's aggressiveness cannot be predicted early, these patients receive systemic chemotherapy with multiple drugs.
