Ryan J Roberts, Debbie Le, Daniel B Leznoff
The new lanthanide-dicyanoaurate coordination polymers [(n)Bu4N]2[Ln(NO3)4Au(CN)2] (Ln = Sm, Dy) and Sm[Au(CN)2]3·3H2O were prepared and structurally characterized and their luminescence spectra described. The emissions of solid-solutions of [(n)Bu4N]2[Ln(NO3)4Au(CN)2] (Ln = Ce, Sm, Eu, Tb, and Dy) were explored with an emphasis on their capacity for luminescent color tuning and white-light emission via the selection of composition, excitation wavelength, and temperature. Specifically, the binary solid-solutions [(n)Bu4N]2[Ce0...

An increasing number of patients are being treated with cardiovascular implantable electronic devices (CIEDs), many of which are MR conditional. There is a lack of literature on the safe scanning of MR conditional CIEDs. This review article discusses MR imaging safety in patients with implanted CIEDs. Guidelines on safe use and indications of imaging patients with MR conditional CIEDs are described, followed by a pictorial essay of the radiographic features of these devices. We also discuss the challenges of monitoring the patient in the MR environment, advances in MRI conditional imaging of devices, availability, limitations and workflow including vendor-specific and other collaborative efforts to simplify the scanning process...

Contrast-induced encephalopathy (CIE) is a rare neurological complication following the administration of injectable intravascular contrast media. Patients with CIE present a wide spectrum of symptoms such as headache, transient cortical blindness, seizure and focal neurological deficits. The diagnosis of CIE requires a high index of suspicion. Its early recognition is of paramount importance in instituting the appropriate supportive treatment in the form of intravenous fluids and also in avoiding unnecessary potentially harmful treatment such as intravenous thrombolysis for suspected ischemic stroke...

BACKGROUND: Studies have shown that remote monitoring (RPM) of implantable cardioverter defibrillators (ICDs) is at least comparable to in-clinic follow-up with regard to clinical outcomes and might be cost-effective, yet RPM is not standard clinical practice within Europe. Better insight into the patient perspective on RPM may aid in its acceptance, implementation and reimbursement. This narrative review 1) summarizes existing evidence on the impact of RPM on patient reported outcomes and 2) discusses future directions in examining the patient perspective...

BACKGROUND: Patients' illness perceptions are associated with psychological wellbeing and can be measured with the Brief Illness Perception Questionnaire (B-IPQ). However, little is known about illness perceptions in patients with heart failure. We examined the dimensional structure, validity and clinical and psychological correlates of the B-IPQ in Dutch, French and German patients with heart failure and an implantable cardioverter defibrillator (ICD). METHOD: European heart failure patients (n=585) participating in the REMOTE-CIED study completed a set of questionnaires 1-2weeks post ICD-implantation, including the B-IPQ...

Indicator cotton swabs have been developed in order to enable faster, less expensive, and simpler information gathering of a wound status. Swabs are normally used for cleaning the wound, but here, they were covalently functionalized with indicator chemistry. Thus, they in principle enable simultaneous wound cleaning and wound pH detection. Using an indicator dye with a color change from yellow to red, combined with an inert dye of blue color, a traffic light color change from green to red is induced when pH increases...

Aged skin is reported to be associated with unattractive skin color changes and solar elastosis. However, comparative studies have not documented the possible correlation between the two factors. This study investigated the plausible relationship between the facial skin color of elderly Asians and solar elastosis. A total of 22 skin specimens were collected from 22 Korean patients who underwent cheek skin biopsies. Skin color was quantitatively measured using colorimetric photography techniques to produce CIE L*a*b* values; the degree of solar elastosis was quantifiably assessed using a histologic grading scale...
