Unilateral diaphragmatic paralysis, resulting from nerve or muscle injuries, is an uncommon phenomenon often missed due to its asymptomatic nature. This condition can lead to decreased pulmonary function, particularly in patients with underlying comorbidities or cardiopulmonary issues. Identification and understanding of the underlying cause of the paralysis are essential for effective management and improved patient outcomes.

The influence of neural activity on astrocytes and their reciprocal interactions with neurons has emerged as an important modulator of synapse function. Astrocytes exhibit activity-dependent changes in gene expression, yet the molecular mechanisms by which they accomplish this have remained largely unknown. The molecular signaling pathway, Sonic hedgehog (Shh), mediates neuron-astrocyte communication and regulates the organization of cortical synapses.

Background: Misclassification bias is introduced into medical claims-based research because of reliance on diagnostic coding rather than full medical record review. We sought to characterize this bias for idiopathic intracranial hypertension (IIH) and evaluate strategies to reduce it.

Methods: A retrospective review of medical records was conducted using a clinical data warehouse containing medical records and administrative data from an academic medical center.
