Elevated brain-derived cell-free DNA among patients with first psychotic episode - a proof-of-concept study.

Schizophrenia is a common, severe, and debilitating psychiatric disorder. Despite extensive research there is as yet no biological marker that can aid in its diagnosis and course prediction. This precludes early detection and intervention.

Increased Uniformity in Diagnostic Accuracy of Pigmented Lesions Using Electrical Impedance Spectroscopy Information.

Background: Novel non-invasive technologies augment information available to a clinician to enhance diagnosis. Electrical impedance spectroscopy (EIS) is a highly sensitive technology used before biopsy to differentiate equivocal lesions through differences in electrical resistance of benign versus malignant cells. A recent study of an EIS device approved by the United States Food and Drug Administration supported this device's impact on clinical management among dermatology residents.

Comparable reliability and acceptability of telepsychiatry and face-to-face psychiatric assessments in the emergency room setting.

Objective: This study aims to compare the reliability and acceptability of psychiatric interviews using telepsychiatry and face-to-face modalities in the emergency room setting.

Methods: In this prospective observational feasibility study, psychiatric patients ( = 38) who presented in emergency rooms between April and June 2020, went through face-to-face and videoconference telepsychiatry interviews in a non-randomised varying order. Interviewers and a senior psychiatry resident who observed both interviews determined diagnosis, recommended disposition and indication for involuntary admission.

Patient knowledge of FDA-mandated sunscreen labeling terminology: A cross-sectional survey.

Background: Insufficient understanding of sunscreen labeling terminology is a barrier to effective use. The Food and Drug Administration (FDA) issued the "final rule" on sunscreen labeling in 2011, in an effort to promote effective usage. However, relatively little is known about patient knowledge of sunscreen labeling terminology.
