Photoluminescent lanthanide complexes of Eu and Tb as central atoms and ,-diisopropyl-[2,2'-bipyridine]-6,6'-dicarboxamide as ligand were synthesized. The structure of these complexes was established by single-crystal X-ray diffraction, mass spectrometry, H and C nuclear magnetic resonance, ultraviolet-visible, infrared spectroscopy, and thermogravimetry. Bipyridinic ligands provide formation of coordinatively saturated complexes of lanthanide ions and strong photoluminescence (PL). The Eu- and Tb-complexes exhibit PL emission in the red and green regions observed at a 340 nm excitation. The quantum yield for the complexes was revealed to be 36.5 and 12.6% for Tb- and Eu-complexes, respectively. These lanthanide compounds could be employed as photoluminescent solid-state compounds and as emitting fillers in polymer (for example, polyethylene glycol) photoluminescent materials.

Purpose: The value of genetic information for improving the performance of clinical risk prediction models has yielded variable conclusions. Many methodological decisions have the potential to contribute to differential results. We performed multiple modeling experiments integrating clinical and demographic data from electronic health records (EHR) with genetic data to understand which decisions may affect performance.

Introduction: Implementation of clinical practice guidelines, an important strategy in the prevention of pressure injuries, enables the nurse to interpret evidence-based guideline recommendations, reduce errors, ensure compliance and standardisation of complex processes, manage patient-related risks and systematically regulate all preventable conditions.
Objective: This study was conducted to ensure the Turkish language and content validity of the Standardised Pressure Injury Prevention Protocol (SPIPP- Adult) Checklist 2.0.
Reassurance for Patients-Essential Not Optional.

Initiative for Slow Medicine, Berkeley, California, USA.
Appropriate patient reassurance is an essential feature of clinical practice. My recent experience as a patient, interpreted via my expertise as a health services researcher, led me to insights on ideal and suboptimal reassurance styles in the context of worrisome symptoms. Reassurance is complex: often poorly defined in the scientific literature, rarely rigorously studied, imperfectly understood, and requiring some adaptation to each patient situation.

Background: Head and neck cancer (HNC) is amongst the 10 most common cancers worldwide and has a major effect on patients' quality of life. Given the complexity of this unique group of patients, a multidisciplinary team approach is preferable. Amongst the debilitating sequels of HNC and/or its treatment, swallowing, speech and voice impairments are prevalent and require the involvement of speech-language pathologists (SLPs).
