EXPRESS: Vocal and musical emotion perception, voice cue discrimination, and quality of life in cochlear implant users with and without acoustic hearing.

This study aims to provide a comprehensive picture of auditory emotion perception in cochlear implant (CI) users by (1) investigating emotion categorization in both vocal (pseud-ospeech) and musical domains, and (2) how individual differences in residual acoustic hearing, sensitivity to voice cues (voice pitch, vocal tract length), and quality of life (QoL) might be associated with vocal emotion perception, and, going a step further, also with musical emotion perception. In 28 adult CI users, with or without self-reported acoustic hearing, we showed that sensitivity (d') scores for emotion categorization varied largely across the participants, in line with previous research. However, within participants, the d' scores for vocal and musical emotion categorization were significantly correlated, indicating similar processing of auditory emotional cues across the pseudo-speech and music domains and robustness of the tests.

Primary care follow-up improves outcomes in older adults following emergency general surgery admission.

Background: While preoperative optimization improves outcomes for older adults undergoing major elective surgery, no such optimization is possible in the emergent setting. Surgeons must identify postoperative interventions to improve outcomes among older emergency general surgery (EGS) patients. The objective of this cohort study was to examine the association between early follow-up with a primary care physician (PCP) and the risk of nursing home acceptance or death in the year following EGS admission among older adults.

Auditory Rhythm Encoding during the Last Trimester of Human Gestation: From Tracking the Basic Beat to Tracking Hierarchical Nested Temporal Structures.

Rhythm perception and synchronization to periodicity hold fundamental neurodevelopmental importance for language acquisition, musical behavior, and social communication. Rhythm is omnipresent in the fetal auditory world and newborns demonstrate sensitivity to auditory rhythmic cues. During the last trimester of gestation, the brain begins to respond to auditory stimulation and to code the auditory environment.

Mortality Among Severely Injured Adolescents Admitted to Pediatric vs Adult Trauma Centers.

Importance: Care in a pediatric (vs adult) trauma center improves outcomes for injured children aged 0 to 12 years, but whether pediatric care benefits injured adolescents is unclear.

Objective: To evaluate the association of pediatric vs adult trauma center care with mortality among severely injured adolescents.

Design, Setting, And Participants: This retrospective cohort study was conducted between April 1, 2012, and March 31, 2020, among adolescents aged 12 to 16 years who were admitted to level I or level II adult trauma centers or a level I pediatric trauma center in British Columbia, Canada.

Morphological Evidence for a Unique Neuromuscular Functional Unit of the Human Vocalis Muscle.

Human vocalization is a complex process that is still only partially understood. Previous studies have suggested the possibility of a localized neuromuscular network of the larynx. Here we investigate this structure in human dissection specimens using multiple immunofluorescence and transmission electron microscopy (TEM).
