Article Synopsis
- The study investigates the occurrence and clinical outcomes of IDH1/2 mutations in pediatric gliomas, emphasizing the differences in treatment approaches between pediatric and adult healthcare providers.
- Among 851 pediatric glioma patients analyzed, 78 (9.2%) were found to have IDH1/2 mutations, with higher rates observed in older age groups, particularly among those aged 10-21.
- The research indicates that most patients were managed with observation rather than additional therapies, and while low-grade glioma patients experienced decent long-term survival, high-grade cases showed lower progression-free survival rates, suggesting outcomes were similar to those seen in adults.
Piperaceae family is original from tropical regions and it shows more than 700 species around the world. Piper gaudichaudianum Kunth is the specie more abundant in Brazil, occurring from Northeast to South Brazil. In this paper, it was investigated the influence of some experimental parameters on the pressurized liquid extraction (PLE) of P.

The analysis of extracts was done by gas chromatography with mass spectrometric detection. The identification and quantification was made by co-injections of the extract with certified standards.
