Traditional optical fibers are insensitive to magnetic fields, however many applications would benefit from fiber-based magnetometry devices. In this work, we demonstrate a magnetically sensitive optical fiber by doping nanodiamonds containing nitrogen vacancy centers into tellurite glass fibers. The fabrication process provides a robust and isolated sensing platform as the magnetic sensors are fixed in the tellurite glass matrix. Using optically detected magnetic resonance from the doped nanodiamonds, we demonstrate detection of local magnetic fields via side excitation and longitudinal collection...

One of the "hidden" medical devices in the school setting is the baclofen pump, which is used for the treatment of spasticity. The goals of spasticity treatment are to decrease muscle tone, deformity, and pain in order to maximize function and ease of care for both child and caregiver. The use of an intrathecal baclofen pump, often for children with cerebral palsy, spinal cord injury, brain injury, or stroke, has been effective in spasticity treatment. It is important for school nurses to be aware of the safety implications associated with this type of device...

Clinicians are adult learners in a complex environment that historically does not invest in training in a way that is conducive to these types of learners. Adult learners are independent, self-directed, and goal oriented. In today's fast-paced clinical setting, a practical need exists for nurses and clinicians to master the technology they use on a daily basis, especially as medical devices have become more interconnected and complex. As hospitals look to embrace new technologies, medical device companies must provide clinical end-user training...

BACKGROUND AND AIM: Subcutaneous implantable cardioverter-defibrillator (S-ICD) is an effective and modern tool used to protect patients at risk of sudden cardiac death from potentially life-threatening ventricular arrhythmias. The first S-ICD systems were implanted in Poland in 2014, but since that time the national experience with that therapy has been limited. Our analysis summarizes the single-center experience at the Department of Cardiology and Electrotherapy of the Medical University of Gdansk with the use of S-ICD from the year 2014 to 2017...

BACKGROUND: With the changing conditions of war, maxillofacial injuries are observed more frequently. Particularly in urban areas, high-energy explosive devices (HEEDs), such as improvised explosive devices, are often used alongside long-barreled weapons (LBWs). It is important to use trauma scoring systems and a multidisciplinary approach for medically and accurately responding to the trauma patient in a timely manner. This study aimed to compare the Military Combat Injury Scale (MCIS) and Military Functional Incapacity Scale (MFIS) between injuries sustained by LBWs or HEEDs and to share experiences of an operational field hospital...

Stephen D Silberstein
Migraine varies in its frequency, severity, and impact; treatment should consider these variations and the patient's needs and goals. Migraine pharmacologic treatment may be acute (abortive) or preventive (prophylactic), and patients often require both. New medication devices are available or in development, including an intracutaneous, microneedle system of zolmitriptan and sumatriptan, and breath-powered powder sumatriptan intranasal treatment. Lasmiditan, a 5-HT1F receptor agonist, is in development for acute treatment, as are small molecule calcitonin gene-related peptide (CGRP) receptor antagonists (Gepants) for acute and preventive treatment...

Glioblastoma is an aggressive brain malignancy with poor outcomes. Current standard of care involves surgery, radiotherapy and chemotherapy. Even with optimal treatment, 5-year survival rates are low. Many patients are unable to tolerate the considerable side effects that therapy involves and suffer from low quality of life. Anti-mitotic tumor treating fields have shown potential in treating glioblastoma with data suggesting that they prolong disease-free survival and overall survival. Novocure has marketed a device that generates these fields via externally placed electrodes...

Smartphones and tablets with their nearly unlimited number of different applications have become an integral part of everyday life. Thus, mobile devices and applications have also found their way into the healthcare sector.For developers, manufacturers, or users as well, it is often difficult to decide whether a mobile health application is a medical device.In this context, it is extremely important for manufacturers to decide at an early stage of the development whether the product is to be introduced into the market as a medical device and is therefore subject to the legislation on medical devices...

John W Perry, David Hardy, Shvetank Agarwal, Gautam Agarwal
Hemodialysis Reliable Outflow (HeRO) grafts (Merit Medical Systems, Inc, South Jordan, Utah) provide a means for access in catheter-dependent hemodialysis patients but typically require several weeks for tissue incorporation. Modifying the HeRO graft with an ACUSEAL graft (W. L. Gore & Associates, Newark, Del) can allow immediate cannulation, thus reducing catheter dependence time and its associated complications. A retrospective review of patients at our institution from 2013 to 2016 who underwent placement of a modified HeRO dialysis system with ACUSEAL graft was performed...

OBJECTIVES: Physicians often use computer technologies to assist in work activities, including family-centered rounds (FCR), but little is known about the attitudes of families on the use of these technologies. We aimed to describe these perceptions on the presence and use of computer technologies during FCR. METHODS: We conducted observations of FCR from a parent's visual perspective to "see what they see." This was followed by in-depth interviews with the families of patients admitted to the hospitalist service at our institution to describe their experience with the use of computer technology by the medical team during FCR...

BACKGROUND: Patients with left bundle branch block (LBBB) often respond to cardiac resynchronization therapy (CRT) with left ventricular ejection fraction (LVEF) improvement. Guideline-directed medical therapy (GDMT), not CRT, is first-line therapy for patients with reduced LVEF with LBBB. However, there are little data on how patients with reduced LVEF and LBBB respond to GDMT. OBJECTIVES: This study examined patients with cardiomyopathy and sought to assess rates of LVEF improvement for patients with LBBB compared to other QRS morphologies...

Asthma and chronic obstructive pulmonary disease (COPD) patients are required to inhale forcefully and deeply to receive medication when using a dry powder inhaler (DPI). There is a clinical need to objectively monitor the inhalation flow profile of DPIs in order to remotely monitor patient inhalation technique. Audio-based methods have been previously employed to accurately estimate flow parameters such as the peak inspiratory flow rate of inhalations, however, these methods required multiple calibration inhalation audio recordings...

BACKGROUND: Residual systemic inflammation persists despite suppressive antiretroviral therapy (ART) and is associated with non-AIDS clinical outcomes. We aimed to evaluate the association between ART adherence and inflammation in Ugandans living with HIV who were predominantly receiving nevirapine-based ART with a thymidine analog backbone and were virologically suppressed by conventional assays. METHODS: Plasma concentrations of interleukin-6 (IL-6), D-dimer, soluble (s)CD14, sCD163, the kynurenine/tryptophan (K/T) ratio, in addition to CD8 T-cell activation, were measured at baseline and 6 months after ART initiation in treatment-naïve adults who achieved an undetectable plasma HIV RNA (<400 copies/mL) at their 6-month visit...

An overwhelming majority of hospitalized patients undergo intravenous (IV) catheter insertion in order to receive hydration and necessary medication. Current IV insertion training techniques include manikins that are unable to react or give feedback to the trainee. The Avstick® is a realistic training device that can be worn by an actor, allowing a nurse trainee to perform an IV catheter insertion on a live patient without causing the person harm. The purpose of this study is to demonstrate the effectiveness of the Avstick in nursing education to increase nurse-patient communication and trainee self-efficacy...
