Elective Naloxone-Induced Opioid Withdrawal for Rapid Initiation of Medication-Assisted Treatment of Opioid Use Disorder.

We present a case of elective naloxone-induced opioid withdrawal followed by buprenorphine rescue to initiate opioid use disorder treatment in the emergency department. This strategy may represent a safe alternative to prescribing buprenorphine for outpatient initiation, a method that puts the patient at risk for complications of unmonitored opioid withdrawal, including relapse. After confirmation that the naloxone-induced withdrawal was adequately treated with buprenorphine, the patient was discharged with prescribed buprenorphine to follow up in an addiction medicine clinic, where he was treated 2 days later.

Flow control using audio tones in resonant microfluidic networks: towards cell-phone controlled lab-on-a-chip devices.

Fluid control remains a challenge in development of portable lab-on-a-chip devices. Here, we show that microfluidic networks driven by single-frequency audio tones create resonant oscillating flow that is predicted by equivalent electrical circuit models. We fabricated microfluidic devices with fluidic resistors (R), inductors (L), and capacitors (C) to create RLC networks with band-pass resonance in the audible frequency range available on portable audio devices.

A Bioimpedance Analysis Platform for Amputee Residual Limb Assessment.

Objective: The objective of this research was to develop a bioimpedance platform for monitoring fluid volume in residual limbs of people with trans-tibial limb loss using prostheses.

Methods: A customized multifrequency current stimulus profile was sent to thin flat electrodes positioned on the thigh and distal residual limb. The applied current signal and sensed voltage signals from four pairs of electrodes located on the anterior and posterior surfaces were demodulated into resistive and reactive components.

Does temporary socket removal affect residual limb fluid volume of trans-tibial amputees?

Background: Lower-limb prosthesis users typically experience residual limb volume losses over the course of the day that can detrimentally affect socket fit.

Objectives: To determine whether temporarily doffing the prosthesis encouraged residual limb fluid volume recovery and whether the recovered fluid was maintained.

Study Design: Experimental design.

Device to monitor sock use in people using prosthetic limbs: technical report.

A device using radio frequency identification (RFID) technology was developed to continuously monitor sock use in people who use prosthetic limbs. RFID tags were placed on prosthetic socks worn by subjects with transtibial limb loss, and a high-frequency RFID reader and antenna were placed in a portable unit mounted to the outside of the prosthetic socket. Bench testing showed the device to have a maximum read range between 5.

Assessment of CPR interruptions from transthoracic impedance during use of the LUCAS™ mechanical chest compression system.

Background: Quality of cardiopulmonary resuscitation (CPR) is a key determinant of outcome following out-of-hospital cardiac arrest (OHCA). Recent evidence shows manual chest compressions are typically too shallow, interruptions are frequent and prolonged, and incomplete release between compressions is common. Mechanical chest compression systems have been developed as adjuncts for CPR but interruption of CPR during their use is not well documented.
