Randomized Controlled Trial Multicenter Study Comparative Study
Symptomatic Adjacent Level Disease Requiring Surgery: Analysis of 10-Year Results From a Prospective, Randomized, Clinical Trial Comparing Cervical Disc Arthroplasty to Anterior Cervical Fusion.
Ten-year follow-up data from the US Food and Drug Administration investigational device exemption trial comparing BRYAN® Cervical Disc (Medtronic, Dublin, Ireland) arthroplasty to anterior cervical discectomy and fusion (ACDF) demonstrated that disc arthroplasty maintained range of motion and improvements in overall success and neck disability. ⋯ Compared with ACDF, fewer patients with the BRYAN® disc required surgery for symptomatic adjacent level degeneration, but this did not achieve statistical significance. Analysis of combined study data using Bryan and Prestige discs shows significant differences in SADLRS as early as 7 yr.

Most of the patients with Parkinson's disease suffer from speech disorders characterized mainly by dysarthria and hypophonia. ⋯ Our findings suggest mechanisms of neuronal degradation due to Parkinsonian speech disorders and their possible compensation. As impairment in sharply tuned units may be compensated by broadly tuned ones, the proposed compensation model appears to be suboptimal, lending support to the persistence of speech disorders in the course of the disease.

Physicians are poorly trained in balancing the demands of a career in medicine and maintaining personal health. Physician burnout occurs due to demanding hours and psychological conditions unique to the field. Programs that address overall well-being early in residency are necessary to prevent physician burnout and promote physician mental health. ⋯ Residency-incorporated wellness programs are achievable and can benefit resident mental health. Lack of a control group limits the interpretation of the results. Programs such as these may be implemented to promote well-being and combat physician burnout and its associated mental health abnormalities.
