Patients as researchers - innovative experiences in UK National Health Service research

Consumer involvement is an established priority in UK health and social care service development and research. To date, little has been published describing the process of consumer involvement and assessing ‘consumers’ contributions to research. This paper provides a practical account of the effective incorporation of consumers into a research team, and outlines the extent to which they can enhance the research cycle; from project development and conduct, through data analysis and interpretation, to dissemination. Salient points are illustrated using the example of their collaboration in a research project. Of particular note were consumers’ contributions to the development of an ethically enhanced, more robust project design, and enriched data interpretation, which may not have resulted had consumers not been an integral part of the research team

Overview and status of the 0.5NA EUV microfield exposure tool at Berkeley Lab

A 0.5-NA extreme ultraviolet micro-field exposure tool has been installed and commissioned at beamline 12.0.1.4 of the Advanced Light Source synchrotron facility at Lawrence Berkeley National Laboratory. Commissioning has demonstrated a patterning resolution of 13 nm half-pitch with annular 0.35-0.55 illumination; a patterning resolution of 8 nm half-pitch with annular 0.1-0.2 illumination; critical dimension (CD) uniformity of 0.7 nm 1σ on 16 nm nominal CD across 80% of the 200 um x 30 um aberration corrected field of view; aerial image vibration relative to the wafer of 0.75 nn RMS and focus control and focus stepping better than 15 nm

Achieving diffraction-limited performance on the Berkeley MET5

The Berkeley MET5, funded by EUREKA, is a 0.5-NA EUV projection lithography tool located at the Advanced Light Source at Berkeley National Lab. Wavefront measurements of the MET5 optic have been performed using a custom in-situ lateral shearing interferometer suitable for high-NA interferometry. In this paper, we report on the most recent characterization of the MET5 optic demonstrating an RMS wavefront 0.31 nm, and discuss the specialized mask patterns, gratings, and illumination geometries that were employed to accommodate the many challenges associated with high-NA EUV interferometry

W-Curve Alignments for HIV-1 Genomic Comparisons

The W-curve was originally developed as a graphical visualization technique for viewing DNA and RNA sequences. Its ability to render features of DNA also makes it suitable for computational studies. Its main advantage in this area is utilizing a single-pass algorithm for comparing the sequences. Avoiding recursion during sequence alignments offers advantages for speed and in-process resources. The graphical technique also allows for multiple models of comparison to be used depending on the nucleotide patterns embedded in similar whole genomic sequences. The W-curve approach allows us to compare large numbers of samples quickly.We are currently tuning the algorithm to accommodate quirks specific to HIV-1 genomic sequences so that it can be used to aid in diagnostic and vaccine efforts. Tracking the molecular evolution of the virus has been greatly hampered by gap associated problems predominantly embedded within the envelope gene of the virus. Gaps and hypermutation of the virus slow conventional string based alignments of the whole genome. This paper describes the W-curve algorithm itself, and how we have adapted it for comparison of similar HIV-1 genomes. A treebuilding method is developed with the W-curve that utilizes a novel Cylindrical Coordinate distance method and gap analysis method. HIV-1 C2-V5 env sequence regions from a Mother/Infant cohort study are used in the comparison.The output distance matrix and neighbor results produced by the W-curve are functionally equivalent to those from Clustal for C2-V5 sequences in the mother/infant pairs infected with CRF01_AE.Significant potential exists for utilizing this method in place of conventional string based alignment of HIV-1 genomes, such as Clustal X. With W-curve heuristic alignment, it may be possible to obtain clinically useful results in a short time-short enough to affect clinical choices for acute treatment. A description of the W-curve generation process, including a comparison technique of aligning extremes of the curves to effectively phase-shift them past the HIV-1 gap problem, is presented. Besides yielding similar neighbor-joining phenogram topologies, most Mother and Infant C2-V5 sequences in the cohort pairs geometrically map closest to each other, indicating that W-curve heuristics overcame any gap problem

Automated synthesis of radiopharmaceuticals for positron emission tomography: an apparatus for labelling with [11C] methyl iodide (MIASA)

A fully automated apparatus for the routine synthesis and formulation of short-lived 11C (t1/2 = 20 min) labelled radiopharmaceuticals for positron emission tomography (PET) has been developed. [11C]Carbon dioxide is converted to [11C]methyl iodide, which can be used to label a wide variety of substrates by methylation at C, N, O, or S electron rich centres. The apparatus, MIASA (methyl iodide automated synthesis apparatus), was designed to operate as part of an automated labelling system in a shielded ‘hot’ laboratory. The apparatus was designed without the size constraints of typical instrumentation used in hot cells, although it is compact where necessary. Ample use of indicators and sensors, together with compact design of the reaction flasks for small dead space and efficient evaporation, led to good reliability and performance. The design of the hardware and software is described in this paper, together with a preparation of 3-N-[11C]methylspiperone as a sterile injectable solution in physiological saline

Solvent-Free Continuous Operations Using Small Footprint Reactors: A Key Approach for Process Intensification

A solvent-free approach to intensification of chemical processes is reported. This concept, in which reactions are carried out solvent-free, without the need for further downstream processing, was highlighted first with a full reduction of ethyl nicotinate to ethylpiperidine-3-carboxylate under continuous flow conditions. Using a small footprint reactor, a throughput of 26.4 g h–1 was achieved. Similarly, this approach was used for the telescoped two-step synthesis of 2-propyl phenol (productivity 120 g h–1) and 2-propyl cyclohexanone (productivity 30 g h–1), starting from the commercially available allyl phenol ether via Claisen rearrangement and subsequent reduction.We would like to thank Pfizer Worldwide Research & Development (CB), the EPSRC (RJM, SVL, Grant Codes EP/K009494/1, EP/M004120/1 and EP/K039520/1) and the Woolf Fisher Trust (DEF) for financial support.This is the final version of the article.

Theorizing healthy settings: a critical discussion with reference to Healthy Universities

The settings approach appreciates that health determinants operate in settings of everyday life. Whilst subject to conceptual development, we argue that the approach lacks a clear and coherent theoretical framework to steer policy, practice and research. Aims: To identify what theories and conceptual models have been used in relation to the implementation and evaluation of Healthy Universities. Methods: A scoping literature review was undertaken between 2010-2013, identifying 26 papers that met inclusion criteria. Findings: Seven theoretical perspectives or conceptual frameworks were identified: the Ottawa Charter; a socio-ecological approach (which implicitly drew on sociological theories concerning structure and agency); salutogenesis; systems thinking; whole system change; organisational development; and a framework proposed by Dooris. These were used to address interrelated questions on the nature of a setting, how health is created in a setting, why the settings approach is a useful means of promoting health, and how health promotion can be introduced into and embedded within a setting. Conclusion: Although distinctive, the example of Healthy Universities drew on common theoretical perspectives that have infused the settings discourse more generally. This engagement with theory was at times well-developed and at other times a passing reference. The paper concludes by pointing to other theories that offer value to healthy settings practice and research and by arguing that theorisation has a key role to play in understanding the complexity of settings and guiding the planning, implementation and evaluation of programmes

Shaping The Future: Developing Principles for Policy Recommendations for Responsible Innovation in Virtual Worlds

As Extended Reality (XR) technologies continue to evolve at a rapid pace, they hold the promise of transforming the way we interact both with digital information and the physical world. Whilst Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR) technologies offer unbridled opportunities for social connections, productivity, and play, these rapid technological advancements also pose critical challenges to ethics, privacy, accessibility, and safety. At present, there is little policy documentation that directly addresses the novel affordances posed by XR technologies, leading to a ‘policy void’ in this space. Having clear and effective policy frameworks prior to the widespread adoption of technology encourages and enables responsible and ethical innovation of XR technologies. This workshop is therefore dedicated to developing forward-thinking principles to guide policy recommendations that address potential future vulnerabilities posed by the widespread adoption of XR technologies whilst simultaneously encouraging the responsible innovation of new advancements within XR. To ensure these policy recommendations promote responsible innovation, the workshop will assemble multidisciplinary academics, industry developers and international policymakers. Our goal is to ensure that all perspectives are considered such that we can collaboratively chart a responsible and sustainable course for the XR landscape
