Background: Defibrillation testing can be done either via an external cardiac defibrillator or directly via the implanted defibrillator during implantation (device-based testing). The advantage of one testing methodology over the other has not been adequately studied.
Methods And Results: Seventy-four patients (72% men) were randomized into two groups depending on the defibrillation testing methodology used--external cardiac defibrillation and device-based testing groups. R-wave, pacing threshold, pacing impedance, defibrillation threshold, defibrillation pathway impedance and total procedure time were not significantly different between the two groups.
Conclusions: Device-based testing did not significantly reduce the procedure time. Lead and defibrillation parameters were similar in both the groups; lead repositioning and replacement were required in three patients in the external cardiac defibrillation group.

Background: Only 15% of the nearly 30 million Americans with hearing loss use hearing aids, partly due to high cost, stigma, and limited access to professional hearing care. Hearing impairment in adults can lead to social isolation and depression and is associated with an increased risk of falls. Given the persistent barriers to hearing aid use, the Food and Drug Administration issued a final rule to allow over-the-counter hearing aids to be sold directly to adult consumers with perceived mild to moderate hearing loss at pharmacies, stores, and online retailers without seeing a physician or licensed hearing health care professional.

Purpose: There is evidence of the role of dark adaptation (DA) as a functional biomarker in age-related macular degeneration (AMD) where foveal cones are impacted during the initial stages of AMD. In this study we determine the repeatability of smartphone application (MOBILE DA) to evaluate the cone-mediated dark adaptation (DA) in healthy young adults.
Methods: Testing was done by placing a smartphone in front of the subject in a dark room.
Fever Prevention and Neurological Recovery in In-Hospital Cardiac Arrest Survivors at a Limited-Resource Setting.

Temperature management plays a critical role in the neurological recovery of cardiac arrest survivors. While advanced device-based temperature control systems are prevalent in high-resource settings, their implementation in low-resource environments remains a challenge. This study aimed to examine the impact of fever prevention on neurological outcomes in cardiac arrest survivors managed without device-based temperature control.

Background: The COVID-19 pandemic has significantly affected global health, economies, and societies, and highlighted the urgent need for rapid, sensitive, affordable, and portable diagnostic devices for respiratory diseases, especially in areas with limited resources. In recent years, there has been rapid development in integrated equipments using microfluidic chips and biochemical detection technologies. However, these devices are expensive and complex to operate, showing limited feasibility for in point of care tests (PoCTs).

Purpose: Although several techniques have been described for bent intramedullary nail removal, there is no universally accepted strategy. We hypothesized that a device based on the action principle of a three-point bend fixture could facilitate extraction of bent intramedullary nails; this paper describes its design and experimental testing.
Methods: Five large synthetic left femurs and five steel intramedullary nails were used.
