Clinical and economic burden of varicella in pediatric patients hospitalized in four institutions in Guatemala.

Varicella presents a public health challenge in Guatemala, with limited evidence regarding its impact; vaccine is currently absent from the national immunization program. Generating local data on the economic and health burden can support immunization policies. This study describes the use of hospital resources, costs of care, clinical and demographic characteristics, and complications in children with varicella.

Thoracoabdominal chordoma in a pediatric patient. A rare entity.

Introduction: Chordoma is a rare, slow-growing notochordal neoplasm typical of adults. Less than 5% of the cases occur in children, where they are located at the skull base. Treatment involves surgical resection with or without radiotherapy.

Benchmarking and performance evaluation of a novel deformable image registration software for radiotherapy CT images.

Purpose: We evaluated and benchmarked a novel deformable image registration (DIR) software functionality (DirOne, Cosylab d.d., Ljubljana, Slovenia) by comparing it to two commercial systems, MIM and VelocityAI, following AAPM task group 132 (TG-132) guidelines.

Comparing new tools of artificial intelligence to the authentic intelligence of our global health students.

Introduction: The transformative feature of Artificial Intelligence (AI) is the massive capacity for interpreting and transforming unstructured data into a coherent and meaningful context. In general, the potential that AI will alter traditional approaches to student research and its evaluation appears to be significant. With regard to research in global health, it is important for students and research experts to assess strengths and limitations of GenAI within this space.

Heavy Ion Particle Therapy in Modern Day Radiation Oncology.

Heavy ion radiotherapy is an emerging technology for treating radioresistant solid tumors. Unlike current low-linear energy transfer techniques, heavy ion radiotherapy, such as carbon ion radiotherapy, enhances the biologic effects related to cancer therapy. Prospective clinical evidence has demonstrated feasibility and efficacy in several disease sites, including head and neck, thoracic, central nervous system, gastrointestinal, pelvic tumors, and sarcomas.
