Objective: Type 1 diabetes mellitus (T1D) is a chronic disease that is common in childhood and adolescence, where care and metabolic control are difficult for both adolescents and their parents. Parental participation in the care and treatment process, especially during adolescence when adolescents develop autonomy and take responsibility for self-care, affects both the adolescent's perception of autonomy and may cause difficulties in self-management. This study was conducted to determine the effect of parental support on adolescents' self-efficacy, quality of life (QoL) and glycaemic control in adolescents with T1D.

Article Synopsis
  • - Epithelial ovarian neoplasms usually affect older patients, while germ cell tumors (GCTs) are more common in younger individuals; however, GCTs can appear in older patients often alongside an epithelial tumor, known as somatically derived GCTs.
  • - The case discussed involves a rare mixed GCT affecting both ovaries, featuring elements of a high-grade serous carcinoma, a yolk sac tumor, and choriocarcinoma.
  • - Diagnosing somatically derived GCTs is challenging for pathologists due to their similarity to high-grade epithelial neoplasms, and accurate diagnosis is vital since these tumors tend to have poor outcomes.

Article Synopsis
  • A 6-year-old girl with growth and blood disorders was found to have a specific genetic mutation linked to a potential new hereditary bone marrow failure syndrome.
  • Whole-exome analysis identified a homozygous variant in a gene associated with the Ras-MAPK pathway, which is known to cause RASopathies—a group of genetic diseases with similar symptoms like growth delays and facial features.
  • The study suggests that this mutation may disrupt protein interactions, likely contributing to the girl's unique clinical symptoms, and proposes this gene as a promising candidate for further research into RASopathies.

Article Synopsis
  • Obese children face a higher risk of arrhythmias and sudden death, even if they don’t have heart dysfunction, due to factors like insulin resistance and neurohumoral changes.
  • A study involving 50 obese children assessed various heart rhythm parameters using 12-lead ECGs, focusing on factors like Tp-e time and QT intervals to determine risks associated with ventricular arrhythmia.
  • Results indicated that obese children, especially those with insulin resistance, showed significant changes in heart rhythm parameters, suggesting the need for regular monitoring of their heart health through ECGs and Holter monitoring to prevent potential arrhythmias.
