Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), often necessitates long-term treatment and hospitalizations and also may require surgery. The ( rs3197999 polymorphism is strongly associated with the risk of IBD but its exact clinical correlates remain under investigation. We aimed to characterize the relationships between the rs3197999 genotype and the clinical characteristics in children and adolescents with IBD within a multi-center cross-sectional study.

Assessment of Dried Serum Spots (DSS) and Volumetric-Absorptive Microsampling (VAMS) Techniques in Therapeutic Drug Monitoring of (Val)Ganciclovir-Comparative Study in Analytical and Clinical Practice.

Ganciclovir (GCV) and its prodrug valganciclovir (VGCV) are antiviral medications primarily used to treat infections caused by cytomegalovirus (CMV), particularly in immunocompromised individuals such as solid organ transplant (SOT) recipients. Therapy with GCV is associated with significant side effects, including bone marrow suppression. Therefore, therapeutic drug monitoring (TDM) is mandatory for an appropriate balance between subtherapeutic and toxic drug levels.

Bone Turnover Markers during Growth Hormone Therapy for Short Stature Children Born Small for Gestational Age.

Growth hormone therapy (GHT) can improve growth velocity and final height, but can also accelerate the process of bone growth, which is related to structural bone modeling in both formation and resorption. This study evaluated the capacity of bone turnover markers to predict early growth response to one year of GHT in short stature children born small for gestational age (SGA). This study included 25 prepubertal children born SGA.

Gas Chromatography-Mass Spectrometry-Based Analyses of Fecal Short-Chain Fatty Acids (SCFAs): A Summary Review and Own Experience.

The gut microbiome, crucial to human health, changes with age and disease, and influences metabolic profiles. Gut bacteria produce short-chain fatty acids (SCFAs), essential for maintaining homeostasis and modulating inflammation. Dysbiosis, commonly due to poor diet or lifestyle, disrupts the integrity of the intestinal barrier and may contribute to conditions such as obesity, diabetes, and non-alcoholic fatty liver disease (NAFLD).

Genetic hallmarks and clinical implications of chromothripsis in childhood T-cell acute lymphoblastic leukemia.

Chromothripsis (cth) is a form of genomic instability leading to massive de novo structural chromosome rearrangements in a one-time catastrophic event. It can cause cancer-promoting alterations, such as loss of sequences for tumor-suppressor genes, formation of oncogenic fusions, and oncogene amplifications. We investigated the genetic background and clinical significance of cth in childhood T-cell acute lymphoblastic leukemia (T-ALL) patients.

A DNA Polymerase Subunit Gamma (POLG) Mutation Imposing a Difficult Differential Diagnosis of Hepatic Encephalopathy in a Newborn: A Case Report.

Hepatic encephalopathy (HE) is a condition connected with neuropsychiatric alteration during hepatic failure. The differential diagnosis of HE is challenging due to overlapping symptoms with other conditions. Polymerase subunit gamma (POLG) is a mitochondrial gene, and an infant POLG mutation can manifest with severe and progressive hepatic failure and encephalopathy, imposing a difficult differential diagnosis due to similarities to other conditions.
