Purpose: We present results from a 6-month field trial of a transitional intervention for debilitating primary hyperacusis, including a combination of structured counseling; promotion of safe, comfortable, and healthy sound exposure; and therapeutic broadband sound from sound generators. This intervention is designed to overcome barriers to successful delivery of therapeutic sound as a tool to downregulate neural hyperactivity in the central auditory pathways (i.e.

Purpose: This report describes a hearing device and corresponding fitting protocol designed for use in a transitional intervention for debilitating loudness-based hyperacusis.

Method: The intervention goal is to transition patients with hyperacusis from their typical counterproductive sound avoidance behaviors (i.e.

The formation of pathogenic biofilms on medical devices is a major public health concern accounting for over 65% of healthcare-associated infections and causing high infection morbidity, mortality, and a great burden to patients and the healthcare system due to its resistance to treatment. In this study, we developed a chitosan-based antimicrobial coating with embedded mesoporous silica nanoparticles (MSNs) to load and deliver eugenol, an essential oil component, to inhibit the biofilm formation of common bacteria in medical-device-related infections. The eugenol-loaded MSNs were dispersed in a chitosan solution, which was then cross-linked with glutaraldehyde and drop-casted to obtain coatings.

Beyond reduced audibility, there is convincing evidence that the auditory system adapts according to the principles of homeostatic plasticity in response to a hearing loss. Such compensatory changes include modulation of central auditory gain mechanisms. Earplugging is a common experimental method that has been used to introduce a temporary, reversible hearing loss that induces changes consistent with central gain modulation.

Background: Elective orthopaedic operations were suspended at the start of the COVID-19 lockdown. Three pathways were created to allow patients to undergo urgent elective operations in NHS Tayside as soon as it was deemed safe to do so.

Methods: We examined elective orthopaedic activity in NHS Tayside during and immediately after the Scottish lockdown.

Scholars have increasingly emphasized the importance of using evidence-based programs to promote health and prevent disease. While theoretically and empirically based programs may be effective in carefully controlled conditions, many fail to achieve desired outcomes when implemented in real-world settings. Ensuring high-quality implementation of health promotion programs is critically important as variation in implementation is closely associated with program effectiveness.

Background: Since 2012, all GP practices across Scotland have been supported to take a systematic approach to end-of-life care, by helping them to identify more patients for palliative care through a Palliative Care Directed Enhanced Service (DES). We aimed to understand the impact of this initiative.

Methods: Routine quantitative data from the 2012/13, and 2013/14 DES were collected from regional health boards, analysed and discussed.

Flint Photovoice represents the work of 41 youths and adults recruited to use a participatory-action research approach to photographically document community assets and concerns, critically discuss the resulting images, and communicate with policymakers. At the suggestion of grassroots community leaders, we included policymakers among those asked to take photographs. In accordance with previously established photovoice methodology, we also recruited at the project's outset another group of policymakers and community leaders to provide political will and support for implementing photovoice participants' policy and program recommendations.
