Brain serotonin, oxytocin, and their interaction: Relevance for eating disorders.

Introduction: Eating disorders are characterized by maladaptive eating behaviors and preoccupations around body shape, weight, and eating. The serotonin system has been among the most widely studied neurobiological factors in relation to eating disorders. Recent research also highlighted the role of oxytocin.

The role of pleural pressure in inducing pneumothorax and other adverse effects of positive pressure ventilation.

Mechanical ventilation, essential for critically ill patients, contrasts with natural respiration, primarily due to differences in pleural pressure ( ). Natural inspiration decreases , pulling the lungs away from the thoracic wall, whereas positive pressure inspiration increases , pushing the lungs against the thoracic wall. This shift has several consequences.

Examining Dimensionality and Item-Quality of the Eating Disorder Examination Questionnaire in Individuals With Eating Disorders Using Item Response Theory Analysis.

Objective: The Eating Disorder Examination Questionnaire (EDE-Q) is a widely-used measure of eating-disorder symptoms. However, inconsistent replication of the subscale structure raises concern about validity. To provide a rigorous test of the EDE-Q's dimensionality and item-quality, we applied modern and classical test theory approaches to data obtained from a large, transdiagnostic sample of people with clinical eating disorders.

Oculomotor behaviors in youth with an eating disorder: findings from a video-based eye tracking task.

Background: The oculomotor circuit spans many cortical and subcortical areas that have been implicated in psychiatric disease. This, combined with previous findings, suggests that eye tracking may be a useful method to investigate eating disorders. Therefore, this study aimed to assess oculomotor behaviors in youth with and without an eating disorder.
