For ACC, the ratio of spectral power from 0.8 to 5 Hz to broadband power was used to separate good-quality signals from noise. For EDA, the rate of amplitude change and prevalence of sharp peaks significantly differentiated between good-quality data and noise. Spectral entropy was used to assess PPG and showed significant differences between good-, marginal-, and poor-quality signals. Compound C order EEG data were evaluated using methods to identify a spectral noise cutoff frequency. Patients were asked to rate the usability and comfort of each device in several categories. Patients showed a significant preference for the wrist-worn devices, and the Empatica E4 device was preferred most often. Current wearable devices can provide high-quality data and are acceptable for routine use, but continued development is needed to improve data quality, consistency, and management, as well as acceptability to patients.What is known and objective We investigated the elimination efficiency and pharmacokinetics (PK) parameters of vancomycin (VCM) in patients undergoing continuous haemodiafiltration (CHDF) using a polyethyleneimine-coated polyacrylonitrile membrane (AN69ST) for dosage adjustment. Methods We conducted a retrospective study of CHDF patients treated with VCM from December 2017 to August 2019. We calculated PK parameters of VCM and determined the 24-hour dose required to maintain the target trough concentration of VCM (VCM_trough ). Results and discussion The average (95% CI) volume of distribution and total clearance of VCM were 75.5 L (63.7-87.3 L) and 1.84 L/h (1.38-2.30 L/h), respectively, and the elimination rate constant and half-life were 0.026/h (0.017-0.034/h) and 31.2 h (22.8-39.5 h), respectively. The average AN69ST clearance of VCM (CL_CHDF ) was 0.69 L/h (0.52-0.86 L/h). The estimated average doses required to maintain VCM_trough of 10, 15 and 20 μg/mL were 623.1 mg (379.8-866.4 mg), 934.6 mg (569.7-1299.5 mg) and 1246.2 mg (759.6-1732.8 mg), respectively. What is new and conclusion The PK of VCM and CL_CHDF of AN69ST were clarified. These results suggest that it is possible to adjust the dose of VCM in using AN69ST, which efficiently removes cytokines, and contributes to improvement of serious infections.Purpose Image-Guided RadioTherapy (IGRT) improves tumor control but its intensive use may entrain late side effects caused by the additional imaging doses. There is a need to better quantify the additional imaging doses so they can be integrated in the therapeutic workflow. Currently, no dedicated software enables to compute patient-specific imaging doses on a wide range of systems and protocols. As a first step toward this objective, we propose a common methodology to model four different kV imaging systems used in radiotherapy (Varian's OBI, Elekta's XVI, Brainlab's ExacTrac, and Accuray's Cyberknife) using a new type of virtual source model based on Monte-Carlo calculations. Methods We first describe our method to build a simplified description of the photon output, or virtual source models (VSM), of each imaging system. Instead of being constructed using measurement data, as it is most commonly the case, our VSM is used as the summary of the phase-space files (PSF) resulting from a first Monte Carlo simulhe four imaging systems, VSMs were successfully validated against measurements in homogeneous phantoms, and are therefore ready to be used for future preclinical studies in heterogeneous or anthropomorphic phantoms. The cross system modeling methodology developed here should enable, later on, to estimate precisely and accurately patient-specific 3D dose maps delivered during a large range of kV-imaging procedures.Youth-Led Participatory Action Research (YPAR) is a social justice-focused approach for promoting social change and positive youth development in which youth conduct systematic research and actions to improve their schools and communities. Although YPAR is oriented to generating research for action, with evidence-based recommendations often aimed at influencing adults with power over settings and systems that shape youths' lives, we have little understanding of how YPAR evidence influences the thinking and/or actions of adult policymakers or practitioners. In general, the participatory research field lacks a theoretically informed "use of research evidence" lens, while the use of evidence field lacks consideration of the special case and implications of participatory research. To start to address these gaps, this paper presents a conceptual linkage across these two fields and then provides six illustrative case examples across diverse geographic, policy, and programmatic contexts to demonstrate opportunities and challenges in the use of YPAR evidence for policy and practice. Our illustrative focus here is on U.S. K-12 educational contexts, the most-studied setting in the YPAR literature, but questions examined here are relevant to YPAR and other systems domestically and internationally, including health, educational, and legal systems. HIGHLIGHTS The use of research evidence (URE) field identifies characteristics of research and conditions that strengthen URE. Youth-led Participatory Action Research is a special case for factors that influence research use. Six case examples across diverse K-12 contexts illustrate facilitators and barriers for YPAR use. We propose next steps for community psychology research and action to promote the study and use of YPAR evidence.Lanthanides (Ln) are critical raw materials, however, their mining and purification have a considerable negative environmental impact and sustainable recycling and separation strategies for these elements are needed. In this study, we present the precipitation and solubility behavior of Ln complexes with Pyrroloquinoline quinone (PQQ), the cofactor of recently discovered lanthanide (Ln) dependent methanol dehydrogenase (MDH) enzymes. In this context, we have been able to elucidate the molecular structure of a bio-relevant europium PQQ complex for the first time outside a protein environment. The complex crystallizes as an inversion symmetric dimer, Eu 2 PQQ 2 , with binding of Eu in the biologically relevant pocket of PQQ. LnPQQ and Ln1Ln2PQQ complexes are characterized using Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Infrared (IR) spectroscopy, 151 Eu-Mössbauer spectroscopy, X-ray total scattering, and Extended X-ray Absorption Fine Structure (EXAFS). We show that a natural enzymatic cofactor is capable to achieve separation by precipitation of the notoriously similar, and thus difficult to separate, lanthanides to some extent.
