Background: Opioid-related inpatient hospital stays are increasing at alarming rates. Unidentified and poorly treated opioid withdrawal may be associated with inpatients leaving against medical advice and increased health care utilization. To address these concerns, we developed and implemented a clinical pathway to screen and treat medical service inpatients for opioid withdrawal.

In the paper, we present a novel approach to the optimum design of wearable antenna arrays intended for off-body links of wireless body area networks. Specifically, we investigate a four-element array that has a switchable radiation pattern able to direct its higher gain towards a signal source and a lower gain towards an interference. The aim is to increase the signal to interference ratio.

Obese patients constitute 40% of the adult population. MRIs of obese patients are typically challenging because of the effects of a large field of view on image quality and the increased risk of thermal burns from contact with the bore. In this case report, the impacts of obesity on MRI procedures and safety are introduced.

Article Synopsis
  • The research aims to enhance the efficiency of a wireless body area sensor network used for monitoring individuals in seated and standing positions.
  • The system features three nodes positioned on the user's body, with one fixed on the head and two adjustable on the trunk and leg, allowing optimization of their placement for better performance.
  • An evolutionary strategy optimization algorithm (Estra) combined with electromagnetic analysis software (Remcom XFdtd) is employed to find an optimal setup that balances on-body and off-body data transmission effectively.
