To predict the impact of face personal protective equipment on verbal communication during the SARS-CoV-2 pandemic.

We assessed the effect of common types and combinations of face personal protective equipment on speech intelligibility in quiet and in a simulated noisy environment.

Wearing face personal protective equipment impairs transmission of middle-to-high voice frequencies and affects speech intelligibility. Surgical masks are responsible for up to 23.3% loss of speech intelligibility in noisy environments. The effects are larger in the condition of advanced face personal protective equipment, accounting for up to 69.0% reduction of speech intelligibility.

The use of face personal protective equipment causes significant verbal communication issues. Healthcare workers, school-aged children, and people affected by voice and hearing disorders may represent specific at-risk groups for impaired speech intelligibility.

Functional magnetic resonance imaging (fMRI) allows the measurement of changes in blood flow in association with changes in brain activity. This technique has been used frequently to study brain activation in response to odorous stimuli. The aim of this study was to evaluate the effects of odor delivery conditions on brain responses obtained with fMRI.

Prospective cohort study SETTING Academic institution.

Twenty healthy volunteers (mean age = 29.5years; 9 women, 11 men) participated. Three odor delivery methods were used "tube" (odor presented intranasally with separate tubing for each nostril), "mask" (odor presented in a face mask covering the subject's nose) and "vacuum" (odor presented into the ambient air). Presentation of the pleasant "peach" odor was performed using a computer-controlled olfactometer. Subjects were asked to evaluate the intensity of the odors after each fMRI run.

"Tube" showed higher self-rated odor intensity compared to "mask" and "vacuum" (F = 18.4, p < 0.001). SB290157 purchase Odor intensity had a positive correlation (r = 0.6, p < 0.05) with percent signal change extracted from the secondary olfactory cortex region in the mask condition. In the tube condition, several selected regions of interest (Amygdala, Insula, Thalamus) showed lower activations compared to the other two conditions (p
 < 0.001, mask > tube, vacuum > tube).

Activations of region of interests (ROIs) in response to the odorous stimuli showed differences under the three conditions (mask, tube, vacuum). In this passive fMRI paradigm, this may partly reflect the differences in odor intensity, but also in attention and contextual variables related to odor perception.

To determine pre- and post-treatment factors that are useful for predicting the prognosis of hearing improvement in idiopathic sudden sensorineural hearing loss (ISSHL).

This retrospective study included 332 patients with ISSHL. Patients received intravenous steroid treatment (prednisolone sodium succinate; 120mg/day followed by dose tapering). Complete recovery of hearing levels was defined as a final pure-tone audiometry of ≤ 20dB HL or the same level as the contralateral ear. Patients' age; sex; side of hearing loss; initial hearing level; days from onset to treatment; presence of vertigo, diabetes, and hypertension; and hearing improvement on days 3-4 and 6-7 after treatment initiation were analyzed as potential prognostic factors.

Overall, 109 patients (32%) had complete recovery. Results of the multivariate logistic regression model identified age (odds ratio [OR] = 0.974), initial hearing level (OR = 0.949), vertigo (OR = 0.409), and hearing improvement on days 6-7 after treatment initiation (OR = 1.11) as significant independent predictors of complete recovery. Age ≥ 60years, initial hearing level ≥ 72.5dB HL, and vertigo contributed to poor prognosis. Patients without these three factors and a hearing improvement of ≥ 10dB HL on days 6-7 post-treatment had a complete recovery rate of 80%. Only 1.5% of the patients with 2-3 of these factors and a hearing improvement of < 10dB HL on days 6-7 after treatment initiation achieved complete recovery.

Age, initial hearing level, vertigo, and hearing improvement on days 6-7 after treatment initiation were independent predictors of hearing recovery in ISSHL.

The association between the tumor subsites of the oral cavity and the risk of osteoradionecrosis of the jaw (ORNJ) remains unclear. We study the correlation between oral cavity tumor subsites and the risk of ORNJ in a nationwide population-based database.

We enrolled 16,701 adult patients with oral cavity cancers who were treated with radiotherapy between 2000 and 2013. The subsites of the oral tumor, treatments of oral cavity cancers, and the timing of tooth extraction were examined for their association with ORNJ in oral cancer patients.

903 patients (5.40%) developed ORNJ. Of the relevant variables, pre-RT mandible surgery, tooth extraction either before or after RT, and tumor sites were associated with the risk of ORNJ. The adjusted HRs for ORNJ in the mouth floor, gums, retromolar, and buccal cancer were 2.056 (1.490-2.837), 1.909 (1.552-2.349), 1.683 (1.105-2.562), and 1.303 (1.111-1.528), respectively, compared with the risk of tongue cancer. There was no significant difference in the risk of ORNJ between the pre-RT extraction group, the during-RT extraction group, and the post-RT extraction (less than 6months) group; the post-RT extraction (more than 6months) group had a significantly higher risk of ORNJ.

This study demonstrated that oral cavity tumor subsite is an independent risk factor of ORNJ after RT. Post-RT extraction (less than 6months) group did not carry a significantly higher risk of ORNJ compared with pre-RT extraction group or during RT extraction group.
