[Do We Need more Volunteer Work in Medicine? Project Examples from Trauma Surgery].

The nursing shortage, legal requirements, and funding deficits have led to increasingly poor patient care in German hospitals.Volunteer patient companions offer support by conversing with and caring for patients. This can work to relieve hospital staff while diminishing patients' fears/worries.

Voice handicap in singers.

The study aimed to determine the differences in responses to the Voice Handicap Index (VHI-10) between singers and nonsingers and to evaluate the ranked order differences of the VHI-10 statements for both groups. The VHI-10 was modified to include statements related to the singing voice for comparison to the original VHI-10. Thirty-five nonsingers with documented voice disorders responded to the VHI-10.

Aerodynamic and acoustical measures of speech, operatic, and Broadway vocal styles in a professional female singer.

Understanding how the voice is used in different styles of singing is commonly based on intuitive descriptions offered by performers who are proficient in only one style. Such descriptions are debatable, lack reproducibility, and lack scientifically derived explanations of the characteristics. We undertook acoustic and aerodynamic analyses of a female subject with professional experience in both operatic and Broadway styles of singing, who sang examples in these two styles.
