Aims
Psychosis is a major mental illness with first onset in young adults. The prognosis is poor in around half of the people affected, and difficult to predict. The few tools available to predict prognosis have major weaknesses which limit their use in clinical practice. We aimed to develop and validate a risk prediction model of symptom non-remission in first-episode psychosis.
MethodOur development cohort consisted of 1027 patients with first-episode psychosis recruited between 2005 to 2010 from 14 early intervention services across the National Health Service in England. Our validation cohort consisted of 399 patients with first-episode psychosis recruited between 2006 to 2009 from a further 11 English early intervention services. The one-year non-remission rate was 52% and 54% in the development and validation cohorts, respectively. Multivariable logistic regression was used to develop a risk prediction model for non-remission, which was externally validated.
ResultThe prediction model showed good discrimination (C-statistic of 0.74 (0.72, 0.76) and adequate calibration with intercept alpha of 0.13 (0.03, 0.23) and slope beta of 0.99 (0.87, 1.12). Our model improved the net-benefit by 16% at a risk threshold of 50%, equivalent to 16 more detected non-remitted first-episode psychosis individuals per 100 without incorrectly classifying remitted cases.
ConclusionOnce prospectively validated, our first episode psychosis prediction model could help identify patients at increased risk of non-remission at initial clinical contact.

Background:
Shortages of personal protective equipment during the coronavirus disease 2019 (COVID-19) pandemic have led to the extended use or reuse of single-use respirators and surgical masks by frontline healthcare workers. The evidence base underpinning such practices warrants examination.
Objectives:To synthesize current guidance and systematic review evidence on extended use, reuse, or reprocessing of single-use surgical masks or filtering face-piece respirators.
Data sources:We used the World Health Organization, the European Centre for Disease Prevention and Control, the US Centers for Disease Control and Prevention, and Public Health England websites to identify guidance. We used Medline, PubMed, Epistemonikos, Cochrane Database, and preprint servers for systematic reviews.
Methods:Two reviewers conducted screening and data extraction. The quality of included systematic reviews was appraised using AMSTAR-2. Findings were narratively synthesized.
Results:In total, 6 guidance documents were identified. Levels of detail and consistency across documents varied. They included 4 high-quality systematic reviews: 3 focused on reprocessing (decontamination) of N95 respirators and 1 focused on reprocessing of surgical masks. Vaporized hydrogen peroxide and ultraviolet germicidal irradiation were highlighted as the most promising reprocessing methods, but evidence on the relative efficacy and safety of different methods was limited. We found no well-established methods for reprocessing respirators at scale.
Conclusions:Evidence on the impact of extended use and reuse of surgical masks and respirators is limited, and gaps and inconsistencies exist in current guidance. Where extended use or reuse is being practiced, healthcare organizations should ensure that policies and systems are in place to ensure these practices are carried out safely and in line with available guidance.

The Spalding Gentlemen's Society is one of the oldest extant learned societies in the world. At the time of its foundation over 300 years ago such societies were popular and membership was viewed as an important attribute of middle-class life. Most societies were short-lived and extant references to them are rare. What sets Spalding over all others is not only its longevity but also the quality of its records, which contain numerous references to music. This article aims to present the musical activities of the Society and to put them into the context of the early eighteenth-century English and European musical world. It begins with a discussion of the annual anniversary concerts and a detailed study of the 1738–46 programmes, commenting on the music performed and those who took part; these programmes are given as appendices. This research is further augmented by an examination of the music-related matters discussed at their meetings and other events that took place in Spalding. It may be impossible to ascertain how unique the Society's musical activities were, but it is rare to have such detail, and this is the first time that these important records, at least in relation to music, have been discussed in any depth.

Objective
The Crunch&Sip programme is a school-based nutrition initiative designed to increase the fruit, vegetable and water intakes of primary-school children. In recognition of the notable deficits in children’s vegetable consumption, the present study explored the receptivity of school staff to a realignment of the Crunch&Sip programme to feature a primary focus on vegetable consumption. This involved investigating school staff members’ perceptions of relevant barriers, motivators and facilitators.
DesignA multi-method approach was adopted that involved four focus groups and a survey (administered in paper and online formats) containing a mixture of open- and closed-ended items.
SettingWestern Australia.
SubjectsStaff from Western Australian schools participated in the focus groups (n 37) and survey (n 620).
ResultsSchool staff were strongly supportive of modifying the Crunch&Sip programme to focus primarily on children’s vegetable consumption and this was generally considered to be a feasible change to implement. Possible barriers identified included children’s taste preferences and a perceived lack of parental support. Suggested strategies to overcome these barriers were education sessions for parents and children, teachers modelling vegetable consumption for their students and integrating vegetable-related topics into the school curriculum.
ConclusionsSchool staff are likely to support the introduction of school-based nutrition programmes that specifically encourage the consumption of vegetables. Potential barriers may be overcome through strategies to engage parents and children.

Objective
To identify the features of a nutrition education programme for disadvantaged adults deemed most attractive and useful by participants.
DesignA two-year, multi-method, qualitative evaluation of pre and post data collected from programme participants. Data were imported into NVivo10 for coding to facilitate a thematic analysis.
SettingWestern Australia.
ParticipantsIndividuals attending the Western Australian FOODcents nutrition education programme that is designed to provide knowledge and skills needed to consume a healthy diet on a budget. Focus groups were conducted several weeks after course completion (five groups, forty-seven participants), observations were conducted during FOODcents sessions (thirty-one observation episodes, 237 participants), and open-ended questions were asked in pre–post hard-copy surveys administered in sessions (n 927) and an online survey administered on average six weeks after course completion (n 114).
ResultsThe course attributes that were found to be especially important to participants were: (i) user-friendly, practical information that could be immediately translated to their daily lives; (ii) experiential learning that involved direct contact with food products; and (iii) opportunities for social interaction. These aspects of nutrition education were described as being highly influential in the decision to participate in the course, the application of the information in their subsequent food purchase and preparation activities, and their word-of-mouth communications with others about the course.
ConclusionsIncorporating aspects of most importance to participants into nutrition education programme delivery and promotion may increase joining rates, enjoyment, satisfaction with course content and, ultimately, the uptake of recommended behaviours.

Objective
For more than 20 years, the FOODcents adult nutrition education programme has been delivered to Western Australians. The aim of the programme is to provide disadvantaged individuals with the knowledge, skills and motivation to buy healthy foods on a limited budget. The present study evaluated whether the FOODcents curriculum and the way it is delivered are effective in improving participants’ nutrition-related knowledge and behaviours.
DesignEvaluation data were collected via in-session pre–post questionnaires and a post-course online questionnaire.
SettingWestern Australia.
SubjectsData were collected from participants attending just over one-half (54 %) of the FOODcents courses conducted over the two-year evaluation period. In total, 927 course participants provided usable data.
ResultsAfter exposure to the course, respondents demonstrated an improved ability to: (i) categorize foods according to the frequency with which they should be consumed and the proportion of the food budget that should be allocated to them; (ii) correctly interpret nutrition labels on food products; and (iii) appreciate the link between diet/obesity and a range of diseases. Improvements in the latter were especially pronounced among participants of low socio-economic status. In terms of behaviour change, significant improvements in fruit and vegetable consumption were reported, along with reductions in the consumption of fast food. Participants of low socio-economic status reported the greatest changes.
ConclusionsThe results indicate that the FOODcents nutrition education programme improves participants’ nutrition-related knowledge and behaviours.

Summary
Introduction to the National Videogame Archive
Formed in 2008 as a partnership between the National Media Museum in Bradford, West Yorkshire, and Nottingham Trent University (NTU) and drawing on expertise from colleagues at Bath Spa University, the National Videogame Archive (NVA) aims to collect, interpret, make accessible for study and research and, where possible, exhibit videogames and the associated ephemera of videogame cultures.
Formerly known as the National Museum of Photography, Film and Television, the National Media Museum changed its name in 2006 to encompass wider forms of media and reflect the radical impact of digital technology. As a key part of this refocusing, in 2007 the Museum created a new Curator of New Media role to widen the collection within the areas of internet and computing technology, videogames and digital art. At the same time, researchers at Nottingham Trent University and Bath Spa University were conducting feasibility research to investigate the efficacy of formal preservation and exhibition strategies and environments for UK videogames. Following consultation, the NVA – a sub-division of the Museum's National New Media Collection – was launched in October 2008 (National Media Museum, 2010)
The NVA aims to preserve, analyse and display the products of the global videogame industry by placing the games in their historical, social, political and cultural contexts. This means treating videogames as more than digital code that can be dissected and emulated or as a system of rules or representations. At the heart of the NVA is a respect for the material form of the game as well as the box art, manuals, advertising, marketing and merchandizing materials that support it and give it meaning and context.
In addition to collecting, curating and archiving these vital parts of popular culture, the ongoing research of the NVA is oriented around exploring and devising innovative and engaging ways to exhibit and analyse videogames for a general audience. This involves considering the interpretation and display of videogame experiences for diverse audiences that might include adepts and non-adepts alike, and exhibition in environments such as museum galleries which are not normally conducive to videogame play (see e.g. Newman, 2009, 2011, 2012; Newman and Woolley, 2009).

Simple alkanedithiols exhibit the same molecular conductance whether measured in air, under vacuum or under liquids of different polarity. Here, we show that the presence of water ‘gates’ the conductance of a family of oligothiophene–containing molecular wires, and that the longer the oligothiophene, the larger is the effect; for the longest example studied, the molecular conductance is over two orders of magnitude larger in the presence of water, an unprecedented result suggesting that ambient water is a crucial factor to be taken into account when measuring single molecule conductances (SMC), or in the design of future molecular electronic devices. Theoretical investigation of electron transport through the molecules, using the ab initio non-equilibrium Green's function (SMEAGOL) method, shows that water molecules interact with the thiophene rings, shifting the transport resonances enough to increase greatly the SMC of the longer, more conjugated examples.

Until recently, the synthesis of polythiophenes using Suzuki chemistry has proven difficult because of the ready protodeborylation of thiophene boronates. However, we now report that the new generation of bulky, electron-rich Pd(0)-phosphane catalysts are effective and reliable for the preparation of regioregular polyalkylthiophenes using Suzuki coupling. Moreover, the monomers can be prepared in high yield by Ir-catalysed borylation, without the need for strong organolithium bases, making this potentially a highly functional group-tolerant approach to polyalkylthiophene derivatives. Perfluoroalkylthiophenes also undergo this reaction.

Although integrated circuit design principles are well understood, they lead to the possibility of radically new modes of device operation when applied to conjugated polymers. Design for speed is very important, even when this is not a primary requirement for a particular application, since supply voltage can be reduced and with it power dissipation. For all-polymer circuits, on thermally insulating plastic substrates, device operating temperature will also be reduced. This has implications for device stability. There are a number of factors that are important in increasing circuit speed. Reduction of channel length must be accompanied by a reduction of gate overlap capacitance and this makes the conventional versions of bottom gate TFT perform badly. Vertical devices are a particularly attractive proposition providing that off-currents can be maintained at a low level. One approach is to use Schottky barriers as the source and drain. Examples will be explained, as will the very unusual mode of operation of such devices. Optimum load structures will also be defined.
