Objective: To determine whether patients with unresponsive wakefulness syndrome respond to auditory stimuli based on changes in facial expressions. Participants: Six patients diagnosed with disorders of consciousness due to brain injury with permission for participation from their doctor. Design: In this hypothesis-driven observational study, the facial expressions of patients with unresponsive wakefulness syndrome were video-recorded for 5 min before and during auditory stimulation in three consecutive weekly sessions. Main Measures: Facial muscle movement was quantified using FaceReader® software (Noldus, Wageningen, Netherlands). Valence/action unit values were plotted to detail facial expression changes. Heart rate values were also plotted. These parameters were compared before and after stimulation. Results: No significant differences in valence integral values or average heart rate were observed between the pre- and intra-stimulus conditions. However, valence signals increased in approximately half of the sessions, indicating that some patients with unresponsive wakefulness syndrome may exhibit emotional responses to auditory stimuli. Analysis of action unit integral values indicated that movement of the eyebrows and eyelids on the upper part of the face occurred during auditory stimulation. Furthermore, the types of auditory stimuli differed depending on the session for the 12 sessions of voice stimuli, whereas the changes in average heart rate differed in each of nine sessions of music stimuli. Because the changes in average heart rate were similar, it is possible that musical stimuli are more suitable than voice stimuli. Conclusion: Some patients with unresponsive wakefulness syndrome may have an emotional response to auditory stimuli. Our findings indicate that it may be possible to distinguish the emotional expression response of a patient based on their facial expression.

We aimed to clarify the sleep status before delirium onset among older adults receiving home care. The sleep status of 21 participants aged ≥65 years was monitored while they slept with a sensor placed under their bedding, after ruling out insomnia and dementia. The incidence of delirium was 28.6%;delirium onset occurred within an average of 2.7 (SD = 12) days after the start of home care among those whose care environment was changed due to hospital discharge or moving. Increased interrupted sleep and activity during sleep indicated that sleep fragmentation occurred before delirium onset. In conclusion, individuals aged ≥65 years and those whose care environment has changed should be screened for delirium because the time to delirium onset is short. Further, interventions to monitor the sleep status and prevent delirium onset should be implemented from the day home care begins.

Objective： To investigate the influence of the depth of skin press in blunt tip placebo acupuncture needles on patient blinding and its relationship to needle ***： Forty healthy volunteers were enrolled as subjects for patient blinding. Four acupuncturists applied the following needles randomly at three points in each forearm： 0.18 mm and 0.25 mm diameter penetrating needles inserted to a depth of 5 mm, and 0.18 mm and 0.25 mm diameter skin-touch needles depressing the skin at the acupoint to a depth of 1 mm and 2 mm from the skin surface. The subjects reported their guesses at the nature of needles they received, and rated needle pain and de qi. A blinding index was calculated to define the success of blinding for ***： The blinding status of subjects for 1 mm press needles of 0.18 mm diameter was ＂random guess＂,but ＂unblinded＂ for 1 mm press needles of 0.25 mm diameter. For 2 mm press needles of both diameters,the blinding status was ＂opposite guess＂ and the blinding status for penetrating needles of both diameters was ＂unblinded.＂ The percentages of ＂felt pain＂ with 2 mm press needles of both diameters were similar to that with penetrating needles, but those were not similar for 1 mm press needles. The frequency of de qi occurrence with 2 mm press needles of 0.18 mm diameter was similar to that of penetrating needles of both ***： Placebo needles of 2 mm press made more subjects guess that the needles penetrated the skin than 1 mm press needles. The use of small diameter needles increased patient blinding.

Objective: Congenital auditory neuropathy(AN) affects hearing and speech development. The degree of hearing difficulty in congenital AN varies as a function of pathology at the inner ear hair cell(IHC) synapses or the auditory nerve. We report a case of a Chinese girl with AN revealed by OTOF(otoferlin) gene mutation analysis who had only a mild hearing ***: A 13-year-old Chinese girl was diagnosed as having congenital AN on the basis of OTOF gene mutation analysis. She manifest a mild sensorineural hearing loss with 50% maximum monosyllable speech discrimination rate, normal DPOAEs(distortion product otoacoustic emissions) beyond ambient noise levels, only SPs(summating potentials) evoked during ECoG(electrocochleography) and absent ABRs(auditory evoked brainstem responses) bilaterally to clicks presented at 100 d Bn HL. She was able to effectively communicate with others by speech reading owing to her mild hearing loss. Moreover, bilateral hearing aids helped her to ***: Our patient was demonstrated to have a mutation on the OTOF gene. Nevertheless, she was able to communicate using auditory visual speech reading in spite of a mild auditory threshold elevation probably due to partial pathology at the IHC synapses or in the auditory nerve.
