Deep neural networks (DNNs) have demonstrated exceptional performance in medical image analysis. However, recent studies have uncovered significant vulnerabilities in DNN models, particularly their susceptibility to adversarial attacks that manipulate these models into making inaccurate predictions. Vision Transformers (ViTs), despite their advanced capabilities in medical imaging tasks, have not been thoroughly evaluated for their robustness against such attacks in this domain.

Unlabelled: Paroxysmal Hypnogenic Dyskinesia (PHD) is a rare movement disorder characterized by involuntary movements, including chorea, athetosis, ballismus, and dystonia, which occur during the Non-Rapid Eye Movement (NREM) sleep stage. Therefore, the diagnosis of PHD is highly crucial due to the presence of differential diagnoses such as epilepsy and other sleep disorders. Although numerous mutations have been identified, the etiology of PHD, which arises from dysregulation in basal ganglia functions, remains unclear.

Article Synopsis
  • The study focused on identifying the clinical characteristics and electrodiagnostic subtypes of Guillain-Barré Syndrome (GBS) in Istanbul over a three-year period.
  • Researchers conducted two electrodiagnostic examinations for 177 GBS patients and compared criteria for differentiating between demyelinating and axonal subtypes, finding varied diagnosis frequencies based on the criteria used.
  • Results indicated that patients with anti-ganglioside antibodies had distinct clinical features, including less sensory symptoms and a more severe disease profile; no significant increase in GBS cases was noted during the COVID-19 pandemic.

Objective: To explore the scope of available research and to identify research gaps on in-vehicle interventions for drowsiness that utilize driver monitoring systems (DMS).

Background: DMS are gaining popularity as a countermeasure against drowsiness. However, how these systems can be best utilized to guide driver attention is unclear.
