Comparing Patient-Specific Variations in Intra-Cochlear Neural Health Estimated Using Psychophysical Thresholds and Panoramic Electrically Evoked Compound Action Potentials (PECAPs).

Purpose: Variations in neural survival along the cochlear implant electrode array leads to off-place listening, resulting in poorer speech understanding outcomes for recipients. Therefore, it is important to develop and compare clinically viable tests to identify these patient-specific intra-cochlear neural differences.

Methods: Nineteen experienced cochlear implant recipients (9 males and 10 females) were recruited for this study.

Characterizing populations prioritized for PrEP in 19 African countries: a review of national guidance.

Introduction: While African countries have expanded access to HIV pre-exposure prophylaxis (PrEP) since 2015, regional targets for PrEP uptake remain unmet. Understanding which populations are prioritized for PrEP at the policy level is an important step in determining the scope of PrEP distribution across Africa and identifying gaps in programme implementation. We reviewed national guidance to characterize populations prioritized for PrEP in Africa.

Resting-State Functional Connectivity Predicts Cochlear-Implant Speech Outcomes.

Objectives: Cochlear implants (CIs) have revolutionized hearing restoration for individuals with severe or profound hearing loss. However, a substantial and unexplained variability persists in CI outcomes, even when considering subject-specific factors such as age and the duration of deafness. In a pioneering study, we use resting-state functional near-infrared spectroscopy to predict speech-understanding outcomes before and after CI implantation.
