Development, feasibility and usability of an app for the correct nutrition of children and adolescents with acute lymphoblastic leukemia

These results align with previous studies demonstrating the potential of digital health tools to enhance treatment compliance and overall well-being in vulnerable populations. By addressing key nutritional challenges faced by children and adolescents with ALL - such as appetite loss, food aversions, gastrointestinal side effects, and food safety concerns - the "Hematognam" app offers a complementary tool to existing dietary counseling, supporting both families and clinicians in daily nutritional management. The development and implementation of the "Hematognam" app proved feasible and effective in addressing the nutritional needs of children and adolescents with ALL during chemotherapy.
