The First Large Absorption Survey in H i (FLASH) is a large-area radio survey for neutral hydrogen in and around galaxies in the intermediate redshift range $0.4\lt z\lt1.0$, using the 21-cm H i absorption line as a probe of cold neutral gas. The survey uses the ASKAP radio telescope and will cover 24,000 deg$^2$ of sky over the next five years. FLASH breaks new ground in two ways – it is the first large H i absorption survey to be carried out without any optical preselection of targets, and we use an automated Bayesian line-finding tool to search through large datasets and assign a statistical significance to potential line detections. Two Pilot Surveys, covering around 3000 deg$^2$ of sky, were carried out in 2019-22 to test and verify the strategy for the full FLASH survey. The processed data products from these Pilot Surveys (spectral-line cubes, continuum images, and catalogues) are public and available online. In this paper, we describe the FLASH spectral-line and continuum data products and discuss the quality of the H i spectra and the completeness of our automated line search. Finally, we present a set of 30 new H i absorption lines that were robustly detected in the Pilot Surveys, almost doubling the number of known H i absorption systems at $0.4\lt z\lt1$. The detected lines span a wide range in H i optical depth, including three lines with a peak optical depth $\tau\gt1$, and appear to be a mixture of intervening and associated systems. Interestingly, around two-thirds of the lines found in this untargeted sample are detected against sources with a peaked-spectrum radio continuum, which are only a minor (5–20%) fraction of the overall radio-source population. The detection rate for H i absorption lines in the Pilot Surveys (0.3 to 0.5 lines per 40 deg$^2$ ASKAP field) is a factor of two below the expected value. One possible reason for this is the presence of a range of spectral-line artefacts in the Pilot Survey data that have now been mitigated and are not expected to recur in the full FLASH survey. A future paper in this series will discuss the host galaxies of the H i absorption systems identified here.
Little guidance exists for developing institutional policies and procedures that support financial management of community-engaged research, including those related to compensating community partners equitably and efficiently for their expertise and time. To address this gap at our institution, the North Carolina Translational and Clinical Sciences Institute at the University of North Carolina at Chapel Hill (UNC) pursued an iterative, multi-pronged approach to identify and address institutional barriers and facilitators related to community partner compensation for research engagement. This case study describes the approach used to involve research administrative leadership, research teams, and community partners at UNC in the identification of institutional barriers to efficient partner compensation. It also elucidates our efforts to develop policies, processes, and resources to address these barriers. The approaches and solutions described can be adapted by other academic research institutions to enhance compensation processes and to facilitate incorporation of community perspectives into the design and implementation of institutional processes that directly impact their engagement in research.
Advancements in VLBI instrumentation, driven by the geodetic community’s goal of achieving positioning accuracy of 1 mm and stability of 0.1 mm/y, have led to the development of new broadband systems. Here, we assess the potential of these new capabilities for space weather monitoring. These enhanced VLBI capabilities were used to investigate interplanetary scintillation (IPS), a phenomenon caused by the scattering of radio waves due to density irregularities in the solar wind. Compact radio sources near the Sun were observed using the AuScope VLBI array in Australia, which consists of 12-m telescopes at Hobart, Katherine, and Yarragadee. The baseline lengths between these telescopes are approximately 3 400 km (Hobart–Katherine), 3 200 km (Hobart–Yarragadee), and 2 400 km (Katherine–Yarragadee). The observations covered solar elongations from 6.5$^\circ$ to 11.3$^\circ$ and frequencies between 3 and 13 GHz. The study focused on phase scintillation as an indicator of turbulence in the solar wind. As the solar elongation decreased, we observed an increase in the phase scintillation index, consistent with theoretical models. Importantly, the broadband system also detected IPS using relatively weak radio sources. Additionally, the phase scintillation increased with baseline length, in agreement with Kolmogorov turbulence with an index of 11/3. These findings demonstrate the effectiveness of geodetic broadband VLBI in capturing detailed features of the solar wind. This capability enables continuous space weather monitoring and advances our understanding of solar and interplanetary dynamics.
This Element explores the idea of publication in media used before, alongside, and after print. It contrasts multiple traditions of unprinted communication in their diversity and particularity. This decentres print as the means for understanding publication; instead, publication is seen as an heuristic term which identifies activities these traditions share, but which also differ in ways not reducible to comparisons with printing. The Element engages with texts written on papyrus, chiselled in stone, and created digitally; sung, proclaimed, and put on stage; banned, hidden and rediscovered. The authors move between Greek inscriptions and Tibetan edicts, early modern manuscripts and AI-assisted composition, monasteries and courts, constantly questioning the term 'publication' and considering the agency of people publishing and the publics they address. The picture that transpires is that of a colourful variety of contexts of production and dissemination, underlining the value of studying 'unprinted' publication in its own right.
Background: Candida auris, a multi-drug resistant fungal pathogen, was introduced to Tennessee in 2021. There are limited studies on the spread of C. auris in highly specialized care settings including outpatient dialysis facilities. Facilities are concerned that C. auris transmission is difficult to prevent in this setting due to patient vulnerability, treatment frequency and length, and isolation challenges. As a result, these facilities may reject patients based on their positive colonization status. In 2023, the Tennessee Department of Health (TDH) conducted two containment-driven colonization screenings in response to a colonized patient receiving dialysis treatment for one month without their status being known to the facility. Methods: An initial point prevalence survey (PPS) was conducted to assess for ongoing transmission among dialysis patients. Patient screening was prioritized for the cohort of patients who received dialysis at the same time as the index patient (Cohort A). The screening was broadened to include patients dialyzed directly before Cohort A (Cohort B) by request of the Cohort B patients. A second PPS was conducted 7 weeks later, targeting the same cohorts. Specimens were collected through supervised patient self-collection of a skin swab from the axilla and groin. Flocked Eswabs were used for collection and transferred in Amies transport media to the Tennessee State Public Health Lab. The presence of C. auris was detected via Polymerase Chain Reaction (PCR). Results: Twenty-three patients (12 from Cohort A; 11 from Cohort B) were screened in the first PPS. One patient from Cohort A tested positive. This colonized patient was determined to be a known C. auris case first detected four months prior, but the patient’s status was never communicated to the dialysis facility from the discharging acute care facility. Eleven patients, excluding the previously identified positives, participated (9 from Cohort A; 2 from Cohort B) in the second PPS; no positives were identified. Discussion: The index patient and an additional patient identified by the PPS both received dialysis at this facility for up to 4 months without facility knowledge. These results suggest that the standard infection control practices at this dialysis facility were adequate to prevent the transmission of C. auris among dialysis patients on multiple shifts. Additionally, patient self-collection identified a known C. auris patient. Future TDH work includes further evaluating the risk of C. auris transmission and developing targeted infection prevention and control practices for the outpatient dialysis setting.
Chronic pain is common and debilitating, and recommended treatments are only moderately effective for pain relief. Focus has shifted to refining targets for change within psychological therapy to improve pain management. Evidence has shown the role of intrusive images in many psychological disorders. However, only a few studies have advanced our knowledge of the presence and impact of mental imagery in chronic pain. This exploratory study aimed to increase our understanding of how people with chronic pain perceive intrusive visual images to influence their daily life. The study employed a qualitative design, using semi-structured interviews to explore the content, emotional valence, cognitive and behavioural impact of pain-related visual images of ten participants with self-reported diagnosis of chronic pain. Data analysis was conducted by performing an inductive thematic analysis. Three key themes were identified: (1) ‘I start to create images in my head’: pain-related mental images, which revolves around descriptions of participants’ most significant visual image; (2) metaphors for pain, related to the imagery as a means to conceptualise and give meaning to the pain; and (3) “With the pain comes the image”: a companion to pain, which focuses on the role of intrusive images in the experience of pain. Results show that pain-related mental imagery appeared to be an intrusive, uncontrollable, and vivid cognitive accompaniment for many pain sufferers. The findings suggest that mental images may serve as an additional target in cognitive behavioural therapy to enhance individuals’ cognitive, behavioural and emotional change.
Key learning aims
(1) To understand the role of mental imagery in the daily life of individuals with chronic pain.
(2) To examine the impact of intrusive images on the emotions, cognitions, and behaviours of people with chronic pain.
(3) To consider clinical implications for CBT interventions targeting pain-related mental images to manage chronic pain.
The National Institute For Health And Care Excellence (NICE) is widely acknowledged as a seminal health technology assessment (HTA) body, known for its transparent and accountable approach to decision-making. This research aimed to investigate the impact of NICE methodology and decisions on international HTA bodies. We sought to identify direct and indirect factors that may influence an international HTA body’s methods or outcomes. To the best of our knowledge, this is the first research to use a qualitative approach to understand the influence of NICE on other HTA bodies.
Methods
We conducted 13 semi-structured qualitative interviews with HTA and market access experts from industry and academia from nine countries (Brazil, Israel, Italy, Japan, Poland, Saudi Arabia, South Korea, Sweden, and the United Arab Emirates). The interview script was organized into three main sections: comparing NICE methods and processes with other HTA bodies; the impact of specific NICE decisions; and Likert scale questions (to allow for comparability of opinions).
Results
Most interviewees believed their local HTA body would consider NICE’s decision when evaluating a medicine. However, the way and extent to which NICE influences HTA varied across countries. The most common means of considering a NICE decision was as background information or context for an HTA evaluation. Generally, interviewees suggested that negative NICE decisions had more impact on local decision-making than positive decisions. Nine of the 13 interviewees agreed or strongly agreed that their country’s HTA body considers the decisions of other HTA bodies in their decision-making process. Eleven of the 13 interviewees agreed or strongly agreed that the development of their country’s HTA body methods and processes was influenced by NICE.
Conclusions
NICE is perceived to be a seminal HTA body, with continued influence on HTA agencies in other countries. However, the mechanisms and extent of this influence varies considerably between countries. We suggest that implicit factors are likely to contribute more to NICE’s influence than individual decisions. Nevertheless, further research is needed to reveal these factors and increase efficiency in international HTA decision-making processes.
The Sustainable Development Goals (SDGs) adopted in 2015 represent an important opportunity to improve learning globally. In this light, this chapter draws on a unique set of early literacy assessment results and demographic information from six African countries (Ghana, Kenya, Liberia, Malawi, Tanzania, and Zambia) to better understand the role that language plays in influencing early reading outcomes. While these data have been published in individual country reports, the information has not been analyzed and released prominently in the narrative surrounding learning outcomes in the region, although data like those presented in this chapter have begun to reverse this tendency. Following this introduction, a brief history is provided of postcolonial trends in literacy acquisition and language policyin sub-Saharan Africa from about 1960 to the present day, documenting the current language of instruction policies for twenty countries. Key questions are also outlined to drive the interest in gaining a better understanding of the variation in literacy acquisition in a selection of target countries for which we have data; then the chapter documents the data and methods usedas well as the results. Finally, the chapter discusses the implications of this work a for future policy and planning to achieve the promises made under the SDGs.
The report examined reciprocal within-person associations among maternal depressive symptoms and offspring depressive, anxiety and irritability symptoms from early childhood to adolescence using a random intercept cross-lagged panel model (RI-CLPM).
Method:
Participants were 609 mother–child dyads participating in the Stony Brook Temperament Study. Child and maternal internalizing symptoms were assessed every 3 years from ages 3 to 15 using maternal report on the Child Behavior Checklist (CBCL) and Diagnostic Inventory for Depression, respectively.
Results:
At the between-person level, maternal depressive symptoms, and child depressive, anxiety, and irritability symptoms were all positively associated with one another. At the within-person level, greater within-person child anxiety symptoms at age 3 predicted both greater child anxiety and depressive symptoms at age 15 via greater child anxiety from ages 6 to 12, and greater within-person child irritability at age 3 predicted greater maternal depressive symptoms at age 15 via greater child irritability from ages 6 to 12.
Conclusions:
Findings reveal novel within-person developmental pathways from early childhood internalizing problems to later internalizing problems in both the child and mother. Intervention and prevention efforts should thus focus on early identification and prevention of childhood internalizing symptoms to reduce negative effects on both child and parent symptoms.
To improve the confidence and preparedness of junior doctors in managing medical or psychiatric emergencies when on call at an inpatient psychiatric unit.
Background
Facilities for emergency care differ between acute medical and psychiatric units. Protocols for managing acutely deteriorating patients and those requiring immediate resuscitation differ across these organisations.
Managing medical emergencies can be stressful for all involved. Junior doctors rotate between services where the level of support varies depending on specialty and setting. For doctors who have worked in a setting where the minimum emergency response includes a Resuscitation team, moving to an environment with less support available is a challenge.
In our unit, the protocol following an urgent call is for the on-call doctor (who has access to basic resuscitation equipment) to attend and assess the need for paramedics and transfer to local hospital. Stress can be worsened by change of environment, change of expectation and concern about best management in new settings.
Method
A cohort of junior doctors were recruited. Baseline assessment included rating their confidence level (scale 1- 10), listing common medical and psychiatric scenarios they had experienced and those they felt least confident managing. Over a period of 10 weeks, follow-up data was obtained. Interventions to improve confidence were assessed during this period, including a handbook and a teaching session on emergency medications. At the end of the project a wordcloud was created in response to the request to “choose 5 words to describe your feelings when called to an emergency”. Identified themes have been fed back to relevant senior staff and will form the basis of future projects.
Result
The initial average confidence score improved from 4.9 to 9.2 and was sustained out to 14 weeks. According the word cloud the most commonly used words were “morale” and “education”.
Conclusion
Prior to the study, confidence levels amongst the Junior Doctors was low. Introduction of the handbook and teaching session led to an improvement which was sustained. Key themes identified using a word cloud were “morale” and “education”.
For junior doctors moving from between services, different expectations and protocol for management of emergencies can influence confidence levels. Psychiatric units should be cognisant of these concerns and implement evidence-based intervention to support junior doctor confidence and improve quality of working experience.
The aim of this project is to improve the training experience of Psychiatry trainees across CNWL. In QI terms, we want to achieve a satisfaction rating of above 7/10 for all themes identified by August 2021.
Method
Collected baseline data on satisfaction and priority ratings on 7 training themes Held discussion groups with trainees for specific themes to generate issues and solutions Developed and provided Quality Improvement training for trainees and trainers, 1:1 support and QI clinics – empowering trainees to develop their own local project and to make changes to issues on the ground Enacted central changes in communication, responsiveness, recognising success.
Reassessed and fedback to the trainees throughout.
Result
Our baseline satisfaction survey was completed in June 2020. Trainees their satisfaction for each theme out of 10 and to rank their priorities for change. Results showed satisfaction was lowest in morale and in safety and highest in education and supervision. Their highest priorities for change were safety, then morale, with induction as the lowest priority.
We repeated the survey in October 2020. This showed improvements in most themes (apart from induction, perhaps due to induction having to be delivered virtually). Satisfaction in key priority areas of morale and safety increased from 4.53 to 6.37, and 5.12 to 6.70 respectively. We also asked what ‘one thing’ would they improve about their training. Key phrases included teaching, on-call, communication and induction.
From this data, and softer feedback from trainees, it is encouraging that we are moving in a positive direction, but we are continuing to make changes.
Conclusion
• Trainees must be central to the work in improving their training
• Using QI methodology helps – developing a structure and breaking down a bigger task helps make a plan
• Feedback is key – but people are busy and receive a lot of emails and requests to fill surveys – catching people ‘in person’ (virtually) was the best way to ensure a lot of responses
• Trainees have loads of great ideas, but they need support, time and resources to be able to develop their projects and changes
• Flexibility is crucial: some topics work better locally, driven by trainees and some require a more coordinated, central role
We hope that developing a structured approach to a large task like improving training will help make changes sustainable, and enables us to share our learning with others.
The COVID pandemic has had both a massive impact on clinical service delivery and the way that training and education is provided. CNWL is a large NHS provider and has approximately 7000 staff working across 150 locations, providing mental health and community health services. In response to the need to share learning across the organisation, a trustwide “Safety Conversation Day” took place to spotlight the work being done to promote safety and to act as a platform to share ideas and learning across the trust. This was the first ever virtual conference organised by the trust.
Method
The one-day conference included virtual posters and an all-day open access virtual conversation delivered via zoom. The day was divided into 6 safety themes: Safety tools; Safer Environments; Supporting and Involving Staff; Safer use of Medicines; See Think Act and Relational Security; and Prevention is Better than Cure. Frontline staff delivered 5-6 short presentations each hour highlighting new ways of working, quality improvement, local research etc.
Staff were also encouraged to submit posters for the event, with webinars held on how to write a poster held prior to the safety conversation to promote engagement. Prizes were awarded for best posters in the different categories.
A mentimeter survey was running throughout the day to get feedback from participants.
Result
This was the largest event of this kind held by the trust. 430 unique viewers logged in during the day to watch the presentations.
Feedback was very positive on the mentimeter survey. 3 questions were asked on a likert scale of: Strongly Disagree – Strongly Agree (rated out of 5):
– ‘I found the posters really useful': 4.5/5
– ‘I found the presentations very useful': 4.6/5
– ‘I will share what I've learnt about safety': 4.6/5
Open space questions and word cloud responses also highlighted qualitative feedback with most frequent responses including ‘inspiring', ‘interesting and ‘stimulating’.
174 posters were presented with good representation from all services and staff groups across the trust (18 on safer use of medicines, 15 on co-production, 52 on quality improvement, 50 on COVID and non-COVID safety, 16 on use of technology, 23 on supporting and involving staff). These posters have since been downloaded 4062 times.
Conclusion
The first CNWL safety conference proved an excellent opportunity to celebrate achievements in patient safety in a very difficult year. It was very well-received and well-attended by staff, promoting maximal learning across the organisation.
The first demonstration of laser action in ruby was made in 1960 by T. H. Maiman of Hughes Research Laboratories, USA. Many laboratories worldwide began the search for lasers using different materials, operating at different wavelengths. In the UK, academia, industry and the central laboratories took up the challenge from the earliest days to develop these systems for a broad range of applications. This historical review looks at the contribution the UK has made to the advancement of the technology, the development of systems and components and their exploitation over the last 60 years.
This study aimed to investigate general factors associated with prognosis regardless of the type of treatment received, for adults with depression in primary care.
Methods
We searched Medline, Embase, PsycINFO and Cochrane Central (inception to 12/01/2020) for RCTs that included the most commonly used comprehensive measure of depressive and anxiety disorder symptoms and diagnoses, in primary care depression RCTs (the Revised Clinical Interview Schedule: CIS-R). Two-stage random-effects meta-analyses were conducted.
Results
Twelve (n = 6024) of thirteen eligible studies (n = 6175) provided individual patient data. There was a 31% (95%CI: 25 to 37) difference in depressive symptoms at 3–4 months per standard deviation increase in baseline depressive symptoms. Four additional factors: the duration of anxiety; duration of depression; comorbid panic disorder; and a history of antidepressant treatment were also independently associated with poorer prognosis. There was evidence that the difference in prognosis when these factors were combined could be of clinical importance. Adding these variables improved the amount of variance explained in 3–4 month depressive symptoms from 16% using depressive symptom severity alone to 27%. Risk of bias (assessed with QUIPS) was low in all studies and quality (assessed with GRADE) was high. Sensitivity analyses did not alter our conclusions.
Conclusions
When adults seek treatment for depression clinicians should routinely assess for the duration of anxiety, duration of depression, comorbid panic disorder, and a history of antidepressant treatment alongside depressive symptom severity. This could provide clinicians and patients with useful and desired information to elucidate prognosis and aid the clinical management of depression.
We studied the compositional turnover in infracommunities and component communities of ecto- and endoparasites infesting a bat, Miniopterus natalensis (Chiroptera, Miniopteridae), across seven sampling sites using the zeta diversity metric (measuring similarity between multiple communities) and calculating zeta decline and retention rate (both scales) and zeta decay (component communities). We asked whether the patterns of zeta diversity differ between (a) infracommunities and component communities; (b) ecto- and endoparasites and (c) subsets of communities infecting male and female bats. The pattern of compositional turnover differed between infracommunities and component communities in endoparasites only. The shape of zeta decline for infracommunities indicated that there were approximately equal probabilities of ecto- and endoparasitic species to occur on/in any bat individual within a site. The shape of zeta decline for component communities suggested the stochasticity of ectoparasite turnover, whereas the turnover of endoparasites was driven by niche-based processes. Compositional turnover in component communities of ectoparasites was more spatially dependent than that of endoparasites. Spatial independence of compositional turnover in endoparasites was due to subcommunities harboured by female bats. We conclude that the patterns of compositional turnover in infracommunities were similar in ecto- and endoparasites, whereas the patterns of turnover in component communities differed between these groups.
When a patient in an in-patient psychiatric setting allegedly commits a crime, psychiatrists are sometimes asked to assess their fitness to be interviewed by the police. This article describes how to conduct this assessment, outlines the criminal justice process leading to police interviews (with particular reference to the legal system in England and Wales) and highlights practical issues to consider when assessing fitness to be interviewed in this context.
Radiocarbon (14C) ages cannot provide absolutely dated chronologies for archaeological or paleoenvironmental studies directly but must be converted to calendar age equivalents using a calibration curve compensating for fluctuations in atmospheric 14C concentration. Although calibration curves are constructed from independently dated archives, they invariably require revision as new data become available and our understanding of the Earth system improves. In this volume the international 14C calibration curves for both the Northern and Southern Hemispheres, as well as for the ocean surface layer, have been updated to include a wealth of new data and extended to 55,000 cal BP. Based on tree rings, IntCal20 now extends as a fully atmospheric record to ca. 13,900 cal BP. For the older part of the timescale, IntCal20 comprises statistically integrated evidence from floating tree-ring chronologies, lacustrine and marine sediments, speleothems, and corals. We utilized improved evaluation of the timescales and location variable 14C offsets from the atmosphere (reservoir age, dead carbon fraction) for each dataset. New statistical methods have refined the structure of the calibration curves while maintaining a robust treatment of uncertainties in the 14C ages, the calendar ages and other corrections. The inclusion of modeled marine reservoir ages derived from a three-dimensional ocean circulation model has allowed us to apply more appropriate reservoir corrections to the marine 14C data rather than the previous use of constant regional offsets from the atmosphere. Here we provide an overview of the new and revised datasets and the associated methods used for the construction of the IntCal20 curve and explore potential regional offsets for tree-ring data. We discuss the main differences with respect to the previous calibration curve, IntCal13, and some of the implications for archaeology and geosciences ranging from the recent past to the time of the extinction of the Neanderthals.
We describe an ultra-wide-bandwidth, low-frequency receiver recently installed on the Parkes radio telescope. The receiver system provides continuous frequency coverage from 704 to 4032 MHz. For much of the band (${\sim}60\%$), the system temperature is approximately 22 K and the receiver system remains in a linear regime even in the presence of strong mobile phone transmissions. We discuss the scientific and technical aspects of the new receiver, including its astronomical objectives, as well as the feed, receiver, digitiser, and signal processor design. We describe the pipeline routines that form the archive-ready data products and how those data files can be accessed from the archives. The system performance is quantified, including the system noise and linearity, beam shape, antenna efficiency, polarisation calibration, and timing stability.
