A computationally efficient speech enhancement pipeline in noisy environments based on a single-processor implementation is developed for utilization in bilateral cochlear implant systems. A two-channel joint objective function is defined and a closed form solution is obtained based on the weighted-Euclidean distortion measure. The computational efficiency and no need for synchronization aspects of this pipeline make it a suitable solution for real-time deployment. A speech quality measure is used to show its effectiveness in six different noisy environments as compared to a similar one-channel enhancement pipeline when using two separate processors or when using independent sequential processing.

Background: Effective staff-to-staff and patient-provider communication in the Emergency Department (ED) is essential for safe, quality care. Routine wearing of Personal-Protective-Equipment (PPE) has introduced new challenges to communication. We aimed to understand the perspectives of ED staff about communicating while wearing PPE, and to identify factors contributing to communication success, breakdown, and repair.

Chronic sleep deprivation and lack of physical exercise may have detrimental effects on overall health, particularly in terms of brain health, with significant implications for cognitive function and well-being. This review explores the impact of chronic sleep deprivation and physical exercise on brain atrophy in mild cognitive impairment (MCI) and Alzheimer's disease (AD). Drawing insights from 40 selected studies, the review synthesizes evidence on these lifestyle factors' correlations with neurodegenerative changes.

Child-directed speech (CDS), which amplifies acoustic and social features of speech during interactions with young children, promotes typical phonetic and language development. In autism, both behavioral and brain data indicate reduced sensitivity to human speech, which predicts absent, decreased, or atypical benefits of exaggerated speech signals such as CDS. This study investigates the impact of exaggerated fundamental frequency (F0) and voice-onset time on the neural processing of speech sounds in 22 Chinese-speaking autistic children aged 2-7 years old with a history of speech delays, compared with 25 typically developing (TD) peers.

Photodynamic therapy (PDT) is a minimally invasive treatment that elicits tumor apoptosis using laser light exclusively applied to the tumor site. IR-783, a heptamethine cyanine (HMC) dye, impedes the proliferation of breast cancer cells, even without light. Although studies have investigated the efficacy of IR-783 in cell and animal studies, its efficacy in clinical settings remains unknown.

: Over the past two decades, the utilization of virtual care in rehabilitation has witnessed a significant surge; this is owing to the widespread availability of technological tools and the global impact of the COVID-19 pandemic. As a result, discussions surrounding the relevance and benefits of telerehabilitation have gained prominence among practitioners, who continually seek to enhance patient care while maintaining high standards of quality. Associated with these discussions are concerns over being able to provide care in an ethical way, as well as addressing equity issues that might be hindered or improved via telerehabilitation.
