Binge eating (BE) is a highly pervasive maladaptive coping strategy in response to severe early life stress such as emotional and social neglect. BE is described as repeated episodes of uncontrolled eating and is tightly linked with comorbid mental health concerns. Despite social stressors occurring at a young age, the onset of BE typically does not occur until adulthood providing an interval for potential therapeutic intervention.

The immediate postoperative period following CNS tumor resection requires intensive care to mitigate complications associated with high morbidity and mortality.
Objective: The primary aim of this study is to comprehensively describe the postoperative complications observed in pediatric patients who underwent primary CNS tumor resection and were subsequently admitted to the pediatric intensive care unit (PICU) at Hospital Universitario Fundación Valle del Lili in Colombia.
Introduction: Hematopoietic cell transplantation (HCT) has become an essential therapeutic modality for pediatric patients with malignant and non-malignant conditions. Despite its effectiveness, many patients experience post-transplant complications often leading into life-threatening conditions requiring specialized care in a Pediatric Intensive Care Unit (PICU). This study aims to describe clinical characteristics associated with mortality in pediatric HCT patients who needed PICU care within 100 days post-transplant in a resource-limited country.

- Inching-locomotion caterpillars (ILAR) serve as inspiration for creating 'inch-worm' robots that utilize biomimicry and can adapt to various environments, including natural and extraterrestrial settings.
- A new mathematical method called Multi-Body Dynamics for Inching-Locomotion Caterpillar Robots (MBD-ILAR) is introduced to simulate the movement of these robots and includes calculations for factors like kinematics and dynamics, focusing on specific robot design aspects.
- A case study was conducted to apply this method, which involved developing a graphical user interface to optimize robot actuator choices and validate the simulation results by analyzing how different parameters influence attachment forces and mechanical performance.
