Purpose: The purpose of this study was to assess the influence of talker protective face coverings on sentence recognition in noise for cochlear implant users.
Method: The AzBio sentences were recorded in three conditions: (a) without any face covering (uncovered), (b) with an N95 mask, or (c) with an N95 mask plus face shield. Target sentences were presented at 60 dB SPL, and the 10-talker masker was presented at 50 dB SPL (10 dB signal-to-noise ratio. Speech recognition for these auditory stimuli was compared across conditions for 21 adult subjects with at least 6 months of cochlear implant (CI) use.
Results: Significant deterioration in sentence recognition was observed for the N95 plus face shield ( = 27% [IQR: 14%-35%]) compared with the N95 ( = 72% [IQR: 55%-78%]) condition and for the N95 compared to uncovered ( = 86% [IQR: 68%-91%]) condition.
Conclusions: Talker protective face coverings have a significant influence on speech recognition in noise for CI users. More research is needed to understand the influence of visual cues with protective face coverings that include a plastic component allowing visualization of the talker's face.

Objectives: The SARS-CoV-2 pandemic required the use of personal protective equipment (PPE) in medical and social contexts to reduce exposure and prevent pathogen transmission. This study aims to analyse possible changes in voice and speech parameters with and without PPE.
Methods: Speech samples using different types of PPE were obtained.

Background: Epidemiological studies report associations of drinking water disinfection byproducts (DBPs) with adverse health outcomes, including birth defects. Here, we used a rat model susceptible to pregnancy loss (full-litter resorption; FLR) and eye malformations (anophthalmia, microphthalmia) to test 11 DBPs, including trihalomethanes, haloacetic acids (HAAs), and nitrogen-containing DBPs (N-DBPs).
Methods: Timed-pregnant F344 rats received gavage doses of chloroform, chlorodibromomethane, iodoform, chloroacetic acid, bromoacetic acid, dibromoacetic acid (DBA), diiodoacetic acid (DIA), trichloroacetic acid (TCA), dibromonitromethane, and iodoacetonitrile on gestation days (GD) 6-10.
The Restylane® portfolio of hyaluronic acid (HA) fillers comprises a broad range of products, each with a unique combination of gel strength/firmness and flexibility. Restylane® Shaype™ (HASHA) is a new HA injectable produced with NASHA-HD™ technology and the most recent addition to the Restylane portfolio. NASHA-HD is an evolution of the NASHA™ platform that adds more HA and uses a more efficient cross-linking even though the degree of modification is kept low.

As trends in life expectancy continue to improve, the burden of loneliness in geriatric populations on a global scale is increasing. With advancing age comes an increase in the number of life events that can perpetuate a state of loneliness such as losing a life partner, dwindling social networks, and deteriorating health conditions. This burden can manifest in a variety of mental and physical consequences.
