Results from a synthetic model of the ITER XRCS-Core diagnostic based on high-fidelity x-ray ray tracing.

A high-fidelity synthetic diagnostic has been developed for the ITER core x-ray crystal spectrometer diagnostic based on x-ray ray tracing. This synthetic diagnostic has been used to model expected performance of the diagnostic, to aid in diagnostic design, and to develop engineering tolerances. The synthetic model is based on x-ray ray tracing using the recently developed xicsrt ray tracing code and includes a fully three-dimensional representation of the diagnostic based on the computer aided design.

Development of an early intervention in psychosis services fidelity questionnaire.

Purpose: We describe the development of an online fidelity questionnaire for early intervention in psychosis (EIP) services, to be used in population-level research, and that can be completed using self-reports from EIP staff.

Methods: A review of key literature sources on the components of EIP services was used to identify those components eligible for inclusion in the questionnaire. A modified Delphi approach, using experts in EIP services, was used to select the most important components to include in the questionnaire.

Preliminary evaluation of a questionnaire for assessing fidelity of early intervention for psychosis services.

Purpose: Fast, easy, and cost-effective methods are needed for fidelity assessment, quality improvement initiatives, and population-based studies in Early Intervention for Psychosis (EIP) services. Having an online questionnaire assessing the fidelity of EIP services, completed by staff self-reports, and having evidence of reliability and validity, could fill that gap. We assess the reliability and validity of the Early Intervention for Psychosis Services Fidelity Questionnaire (EIPS-FQ), developed in Part I of this set of papers.

Commentary: core descriptor sets using consensus methods support 'table one' consistency.

Dedicated anticoagulation management protocols in fragility femoral fracture care - a source of significant variance and limited effectiveness in improving time to surgery: The hip and femoral fracture anticoagulation surgical timing evaluation (HASTE) study.

Introduction: Approximately 20 % of femoral fragility fracture patients take anticoagulants, typically warfarin or Direct Oral AntiCoagulant (DOAC). These can impact timing of surgery affecting patient survival. Due to several possible approaches and numerous factors to consider in the preoperative workup of anticoagulated patients, potential for variations in clinical practice exist.

Design and validation of a GMP stem cell manufacturing protocol for MPSII hematopoietic stem cell gene therapy.

Hematopoietic stem cell gene therapy (HSCGT) is a promising therapeutic strategy for the treatment of neurodegenerative, metabolic disorders. The approach involves the introduction of a missing gene into patients' own stem cells via lentiviral-mediated transduction (TD). Once transplanted back into a fully conditioned patient, these genetically modified HSCs can repopulate the blood system and produce the functional protein, previously absent or non-functional in the patient, which can then cross-correct other affected cells in somatic organs and the central nervous system.

Revisiting the Roles of Catalytic Residues in Human Ornithine Transcarbamylase.

Human ornithine transcarbamylase (hOTC) is a mitochondrial transferase protein involved in the urea cycle and is crucial for the conversion of toxic ammonia to urea. Structural analysis coupled with kinetic studies of rat, bovine, and other transferase proteins has identified residues that play key roles in substrate recognition and conformational changes but has not provided direct evidence for all of the active residues involved in OTC function. Here, computational methods were used to predict the likely active residues of hOTC; the function of these residues was then probed with site-directed mutagenesis and biochemical characterization.

Development and usability testing of an online support tool to identify models and frameworks to inform implementation.

Background: Theories, models and frameworks (TMFs) are useful when implementing, evaluating and sustaining healthcare evidence-based interventions. Yet it can be challenging to identify an appropriate TMF for an implementation project. We developed and tested the usability of an online tool to help individuals who are doing or supporting implementation practice activities to identify appropriate models and/or frameworks to inform their work.

Examining the Backpack Weight Relative to Students' Body Weight Among Urban and Rural Schoolchildren: A Cross-Sectional Study.

Background Schoolbags or backpacks have been an essential part of the education system for a long time. However, a hefty backpack causes the child to arch the back excessively or bend their head and trunk forward to withstand the weight of the schoolbag. If the student carries the backpack on one shoulder, he/she bends to the opposite side to compensate for the extra weight, which may damage the shoulders and spine.

Modelled impact of virtual fractional flow reserve in patients undergoing coronary angiography (VIRTU-4).

Background: The practical application of 'virtual' (computed) fractional flow reserve (vFFR) based on invasive coronary angiogram (ICA) images is unknown. The objective of this cohort study was to investigate the potential of vFFR to guide the management of unselected patients undergoing ICA. The hypothesis was that it changes management in >10% of cases.

A Goffmanian analysis of impact of unclear professional identity and role negotiation of pharmacists in primary care: A multiple case study.

Background: Professional identity and its development is a focus of research, education, and practice. But, there is a lack of how professional identity impacts changes in pharmacists' roles in practice, which are particularly prevalent in primary care teams.

Objectives: This research uses Goffmanian theory, micro-sociologic interactional theory, to describe the outcomes of role negotiation in integrated primary care teams.

Factors contributing to high performance of sows in free farrowing systems.

Background: Pressure to abolish farrowing crates is increasing, and producers are faced with decisions about which alternative system to adopt. For sow welfare, well designed free farrowing systems without close confinement are considered optimal but producers have concerns about increased piglet mortality, particularly crushing by the sow. Reporting accurate performance figures from commercial farms newly operating such systems could inform the transition process.

Assessing the role of Chemokine (C-C motif) ligand 14 in AKI: a European consensus meeting.

Background: Urinary Chemokine (C-C motif) ligand 14 (CCL14) is a biomarker associated with persistent severe acute kidney injury (AKI). There is limited data to support the implementation of this AKI biomarker to guide therapeutic actions.

Methods: Sixteen AKI experts with clinical CCL14 experience participated in a Delphi-based method to reach consensus on when and how to potentially use CCL14.

Understanding the relationship between surfing performance and fin design.

This research aimed to determine whether accomplished surfers could accurately perceive how changes to surfboard fin design affected their surfing performance. Four different surfboard fins, including conventional, single-grooved, and double-grooved fins, were developed using computer-aided design combined with additive manufacturing (3D printing). We systematically installed these 3D-printed fins into instrumented surfboards, which six accomplished surfers rode on waves in the ocean in a random order while blinded to the fin condition.

Can communities be mobilised to build capacity to respond to the COVID-19 pandemic? A qualitative process evaluation.

Objectives: Government guidance to manage COVID-19 was challenged by low levels of health and digital literacy and lack of information in different languages. 'Covid Confidence' sessions (CC-sessions) were evaluated to assess their effectiveness in counteracting misinformation and provide an alternative source of information about the pandemic.

Design: We worked with community anchor organisations to co-ordinate online CC-sessions serving three economically deprived, ethnically mixed, neighbourhoods.

Use of eye-gaze technology feedback by assistive technology professionals: findings from a thematic analysis.

Eye-gaze technology offers professionals a range of feedback tools, but it is not well understood how these are used to support decision-making or how professionals understand their purpose and function. This paper explores how professionals use a variety of feedback tools and provides commentary on their current use and ideas for future tool development. The study adopted a focus group methodology with two groups of professional participants: those involved in the assessment and provision of eye-gaze technology ( = 6) and those who interact with individuals using eye-gaze technology on an ongoing basis ( = 5).

Radiographer training for screening of patients referred for Magnetic Resonance Imaging: A scoping review.

Introduction: Strict safety practices are essential to ensure the safety of patients and staff in Magnetic Resonance Imaging (MRI). Training regarding the fundamentals of MRI safety is well-established and commonly agreed upon. However, more complex aspect of screening patients, such as image review or screening of unconscious patients/patients with communication difficulties is less well discussed.

Handling 'carbon footprint' in orthopaedics.

Introduction: The National Health Service contributes 4%-5% of England and Wales' greenhouse gases and a quarter of all public sector waste. Between 20% and 33% of healthcare waste originates from a hospital's operating room, and up to 90% of waste is sent for costly and unneeded hazardous waste processing. The goal of this study was to quantify the amount and type of waste produced during a selection of common trauma and elective orthopaedic operations, and to calculate the carbon footprint of processing the waste.

The impact of anticoagulant medications on fragility femur fracture care: The hip and femoral fracture anticoagulation surgical timing evaluation (HASTE) study.

Introduction: Due to their hypocoagulable state on presentation, anticoagulated patients with femoral fragility fractures typically experience delays to surgery. There are no large, multicentre studies previously carried out within the United Kingdom (UK) evaluating the impact of anticoagulant use in this patient population. This study aimed to evaluate the current epidemiology and compare the perioperative management of anticoagulated and non-anticoagulated femoral fragility fracture patients.

Grand challenges in entomology: Priorities for action in the coming decades.

Entomology is key to understanding terrestrial and freshwater ecosystems at a time of unprecedented anthropogenic environmental change and offers substantial untapped potential to benefit humanity in a variety of ways, from improving agricultural practices to managing vector-borne diseases and inspiring technological advances.We identified high priority challenges for entomology using an inclusive, open, and democratic four-stage prioritisation approach, conducted among the membership and affiliates (hereafter 'members') of the UK-based Royal Entomological Society (RES).A list of 710 challenges was gathered from 189 RES members.

A control oriented strategy of disruption prediction to avoid the configuration collapse of tokamak reactors.

The objective of thermonuclear fusion consists of producing electricity from the coalescence of light nuclei in high temperature plasmas. The most promising route to fusion envisages the confinement of such plasmas with magnetic fields, whose most studied configuration is the tokamak. Disruptions are catastrophic collapses affecting all tokamak devices and one of the main potential showstoppers on the route to a commercial reactor.

The Minimisation of Cardiovascular Disease Screening for Kidney Transplant Candidates.

: There is increasing evidence that cardiac screening prior to kidney transplantation does not improve its outcomes. However, risk aversion to perioperative events means that, in practice, testing remains common, limiting the availability of 'real-world' data to support any change. Our objective was to assess perioperative and 1-year post-transplant cardiovascular events in a kidney transplant candidate cohort who received minimal cardiovascular screening.
