The COVID-19 pandemic has had a dramatic impact on the health and social care landscape, both in terms of service provision and citizen need. Responsive, evidence-based research is essential to develop and implement appropriate policies and practices that manage both the pandemic itself, and the impact COVID-19 has on other health and social care issues.
To address this, the Wales COVID-19 Evidence Centre (WCEC) was launched in 2021 with the aim of providing the best available, up-to-date, and relevant evidence to inform health and care decision making across Wales.
Methods
Funded by the Welsh Government, the WCEC comprises of a core team and several collaborating partner organizations, including Health Technology Wales, Wales Centre for Evidence-Based Care, Specialist Unit for Review Evidence Centre, SAIL Databank, Public Health Wales, Bangor Institute for Health & Medical Research in conjunction with Health and Care Economics Cymru, and the Public Health Wales Observatory. Over the last year, WCEC has developed its rapid review processes and methodology informed by best international practice and aims to provide around 50 reviews each year. WCEC works alongside various stakeholder groups from health and social care across Wales, and they form an integral part of the review process, from scoping to knowledge mobilization.
Results
To date, the WCEC has produced reviews on a diverse range of COVID-19 topics, including transmission, vaccination uptake (barriers, facilitators and interventions), mental health and wellbeing, as well as face coverings and other preventative interventions. The topics have also covered a wide range of populations, from general public, to healthcare workers, to children. These reviews have been used to inform policy and decision-making, including the Welsh Government’s Chief Medical Officer 21-day COVID-19 reviews.
Conclusions
The WCEC has brought together multiple specialist centers with a diverse range of skills to produce timely reviews of the most up-to-date research to support decision makers across health and social care. These reviews have informed policy and decision-making across Wales.
The authors discuss new sediment coring at the Early Neolithic submerged site of Atlit-Yam, Israel, that reveals stratified archaeological deposits 0.7–0.9m below the seabed. They demonstrate the potential of micro-geoarchaeological analysis to generate new chrono-stratigraphic data for the onset of Early Neolithic coastal occupation in the Eastern Mediterranean.
With the emergence of Internet of Things (IoT) as a new source of “big” data and value creation, businesses encounter novel opportunities as well as challenges in IoT design. Although recent research argues that digital technology can enable new kinds of development processes that are distinctive from their counterparts in the 20th century, minimal attention has been focused on the IoT design process. In order to contextualize New Product Development (NPD) processes for IoT, this paper comprehensively interrogates existing, and emerging development approaches for products, services, software, and integrated products, and several factors that affect designing IoT. This discussion includes the generic development process, the commonalities and differences of different development approaches, and processes. The paper demonstrates that only a few existing approaches reflect vital characteristics of networked artifacts or the integration of data science within the development model, which is one of the key attributes of IoT design. From these investigations, we propose “The Mobius Strip Model of IoT Development ProcessI,” a conceptual process for IoT design, which is distinctive to others. The continuous loops of the IoT design integrate the attributes and phases of different processes and consist of two different development approaches and strategies. Understanding the particular attributes of the IoT NPD process can help novice and experienced researchers in both feeding and drawing insight from the broader design discourse.
We explore how relational identification (RI) complements the influence of relational exchange within work role-relationships. In two temporally-lagged studies, we examine the contribution of RI, after accounting for relational exchange quality (REQ), in predicting organizationally-relevant behaviors and attitudes – namely, (1) interpersonal citizenship behaviors (ICBs; person-focused and task-focused), (2) job satisfaction, and (3) affective organizational commitment. Across samples of ‘non-professional’ (N = 152) and ‘professional’ (N = 197) employees, we found that RI (after accounting for REQ) significantly predicted outcomes. Indeed, we found RI to be the only predictor (after accounting for REQ) with affective commitment (‘non-professional’ sample only), person-focused ICBs (both samples), and task-focused ICBs (both samples). We discuss potential approaches for better specifying both identification and exchange as well as their unique and interactive effects within work role-relationships as well as managerial implications, limitations, and future research directions.
To assess the training and the future workforce needs of paediatric cardiac critical care faculty.
Design:
REDCap surveys were sent May−August 2019 to medical directors and faculty at the 120 US centres participating in the Society of Thoracic Surgeons Congenital Heart Surgery Database. Faculty and directors were asked about personal training pathway and planned employment changes. Directors were additionally asked for current faculty numbers, expected job openings, presence of training programmes, and numbers of trainees. Predictive modelling of the workforce was performed using respondents’ data. Patient volume was projected from US Census data and compared to projected provider availability.
Measurements and main results:
Sixty-six per cent (79/120) of directors and 62% (294/477) of contacted faculty responded. Most respondents had training that incorporated critical care medicine with the majority completing training beyond categorical fellowship. Younger respondents and those in dedicated cardiac ICUs were more significantly likely to have advanced training or dual fellowships in cardiology and critical care medicine. An estimated 49–63 faculty enter the workforce annually from various training pathways. Based on modelling, these faculty will likely fill current and projected open positions over the next 5 years.
Conclusions:
Paediatric cardiac critical care training has evolved, such that the majority of faculty now have dual fellowship or advanced training. The projected number of incoming faculty will likely fill open positions within the next 5 years. Institutions with existing or anticipated training programmes should be cognisant of these data and prepare graduates for an increasingly competitive market.
To assess current demographics and duties of physicians as well as the structure of paediatric cardiac critical care in the United States.
Design:
REDCap surveys were sent by email from May till August 2019 to medical directors (“directors”) of critical care units at the 120 United States centres submitting data to the Society of Thoracic Surgeons Congenital Heart Surgery Database and to associated faculty from centres that provided email lists. Faculty and directors were asked about personal attributes and clinical duties. Directors were additionally asked about unit structure.
Measurements and main results:
Responses were received from 66% (79/120) of directors and 62% (294/477) of contacted faculty. Seventy-six percent of directors and 54% of faculty were male, however, faculty <40 years old were predominantly women. The majority of both groups were white. Median bed count (n = 20) was similar in ICUs and multi-disciplinary paediatric ICUs. The median service expectation for one clinical full-time equivalent was 14 weeks of clinical service (interquartile range 12, 16), with the majority of programmes (86%) providing in-house attending night coverage. Work hours were high during service and non-service weeks with both directors (37%) and faculty (45%).
Conclusions:
Racial and ethnic diversity is markedly deficient in the paediatric cardiac critical care workforce. Although the majority of faculty are male, females make up the majority of the workforce younger than 40 years old. Work hours across all age groups and unit types are high both on- and off-service, with most units providing attending in-house night coverage.
People who have suffered the loss of a loved one may subsequently report sensory experiences of the deceased (termed ‘after-death communications’, or ADCs). Such encounters are common and can be a source of comfort to the bereaved. Nevertheless, there has been limited empirical investigation of this phenomenon, and consequently mental health professionals feel ill-equipped to support those who disclose them.
Aims
To map the phenomenology of ADCs, and identify covariates and effects upon the recipient.
Method
We conducted an online mixed-methods survey comprising 194 items about all aspects of ADCs. A purposive sample of 1004 respondents across three language groups (English, French and Spanish) completed the survey.
Results
The most common form of ADC was during sleep, but large numbers of cases involved sensory modalities of touch, sight, hearing, smell and sense of presence that externalised the phenomenon for the recipient. Variations in incidence with participant gender and language group suggest a psychosocial component. ADCs were typically regarded by the participant as deeply meaningful and comforting. Respondents reported significant increases in their sense of spirituality, but not religiosity.
Conclusions
ADCs are a common feature of bereavement that occur unexpectedly, and are independent of any underlying pathology or psychological need. For the person experiencing the hallucination, they are important and meaningful events that they interpret in terms of continuing bonds with the deceased. This adaptive outcome may be stymied where mental health professionals trivialise or pathologise disclosures about ADCs.
Patients with cyanotic heart disease are at an increased risk of developing thrombosis. Aspirin has been the mainstay of prophylactic anticoagulation for shunt-dependent patients with several reports of prevalent aspirin resistance, especially in neonates. We investigate the incidence of aspirin resistance and its relationship to thrombotic events and mortality in a cohort of infants with shunt-dependent physiology.
Methods:
Aspirin resistance was assessed using the VerifyNow™ test on infants with single-ventricle physiology following shunt-dependent palliation operations. In-hospital thrombotic events and mortality data were collected. Statistical analysis was performed to evaluate the effect of aspirin resistance on in-hospital thrombotic events and mortality risk.
Results:
Forty-nine patients were included with 41 of these patients being neonates. Six patients (12%) were aspirin resistant. A birth weight < 2500 grams was a significant factor associated with aspirin resistance (p = 0.04). Following a dose increase or additional dose administration, all patients with initial aspirin resistance had a normal aspirin response. There was no statistically significant difference between aspirin resistance and non-resistance groups with respect to thrombotic events. However, a statistically significant incidence of in-hospital mortality in the presence of thrombotic events was observed amongst aspirin-resistant patients (p = 0.04) in this study.
Conclusion:
Low birth weight was associated with a higher incidence of aspirin resistance. Inadequate initial dosing appears to be the primary reason for aspirin resistance. The presence of both thrombotic events and aspirin resistance was associated with significantly higher in-hospital mortality indicating that these patients warrant closer monitoring.
The Subglacial Antarctic Lakes Scientific Access (SALSA) Project accessed Mercer Subglacial Lake using environmentally clean hot-water drilling to examine interactions among ice, water, sediment, rock, microbes and carbon reservoirs within the lake water column and underlying sediments. A ~0.4 m diameter borehole was melted through 1087 m of ice and maintained over ~10 days, allowing observation of ice properties and collection of water and sediment with various tools. Over this period, SALSA collected: 60 L of lake water and 10 L of deep borehole water; microbes >0.2 μm in diameter from in situ filtration of ~100 L of lake water; 10 multicores 0.32–0.49 m long; 1.0 and 1.76 m long gravity cores; three conductivity–temperature–depth profiles of borehole and lake water; five discrete depth current meter measurements in the lake and images of ice, the lake water–ice interface and lake sediments. Temperature and conductivity data showed the hydrodynamic character of water mixing between the borehole and lake after entry. Models simulating melting of the ~6 m thick basal accreted ice layer imply that debris fall-out through the ~15 m water column to the lake sediments from borehole melting had little effect on the stratigraphy of surficial sediment cores.
Analyses of macroscopic charcoal, sediment geochemistry (%C, %N, C/N, δ13C, δ15N), and fossil pollen were conducted on a sediment core recovered from Stella Lake, Nevada, establishing a 2000 year record of fire history and vegetation change for the Great Basin. Charcoal accumulation rates (CHAR) indicate that fire activity, which was minimal from the beginning of the first millennium to AD 750, increased slightly at the onset of the Medieval Climate Anomaly (MCA). Observed changes in catchment vegetation were driven by hydroclimate variability during the early MCA. Two notable increases in CHAR, which occurred during the Little Ice Age (LIA), were identified as major fire events within the catchment. Increased C/N, enriched δ15N, and depleted δ13C values correspond with these events, providing additional evidence for the occurrence of catchment-scale fire events during the late fifteenth and late sixteenth centuries. Shifts in the vegetation community composition and structure accompanied these fires, with Pinus and Picea decreasing in relative abundance and Poaceae increasing in relative abundance following the fire events. During the LIA, the vegetation change and lacustrine geochemical response was most directly influenced by the occurrence of catchment-scale fires, not regional hydroclimate.
We describe an adolescent with Streptococcus pneumoniae meningitis and symptomatic high-grade, second-degree atrioventricular block requiring permanent pacemaker placement. It is difficult to ascertain if these two diagnoses were independent or had a causal relationship though ongoing symptoms were not present prior to the infection. Because of this uncertainty, awareness that rhythm disturbances can be cardiac in origin but also secondary to other aetiologies, such as infection, is warranted.
The patient experience of radiotherapy magnetic resonance (MR) simulation is unknown. This study aims to evaluate the patient experience of MR simulation in comparison to computed tomography (CT) simulation, identifying the quality of patient experience and pathway changes which could improve patient experience outcomes.
Materials and Methods:
MR simulation was acquired for 46 anal and rectal cancer patients. Patient experience questionnaires were provided directly after MR simulation. Questionnaire responses were assessed after 33 patients (cohort one). Changes to the scanning pathway were identified and implemented. The impact of changes was assessed by cohort two (13 patients).
Results:
Response rates were 85% (cohort one) and 54% (cohort two). 75% of cohort one respondents found the magnetic resonance imaging (MRI) experience to be better or similar to their CT experience. Implemented changes included routine use of blankets, earplugs and headphones, music and feet-first positioning and further MRI protocol optimisation. All cohort two respondents found the MRI experience to be better or similar to the CT experience.
Findings:
MR simulation can be a comfortable and positive experience that is comparable to that of standard radiotherapy CT simulation. Special attention is required due to the fundamental differences between CT and MRI scanning.
The approach to vascular access in children with CHD is a complex decision-making process that may have long-term implications. To date, evidence-based recommendations have not been established to inform this process.
Methods:
The RAND/UCLA Appropriateness Method was used to develop miniMAGIC, including sequential phases: definition of scope and key terms; information synthesis and literature review; expert multidisciplinary panel selection and engagement; case scenario development; and appropriateness ratings by expert panel via two rounds. Specific recommendations were made for children with CHD.
Results:
Recommendations were established for the appropriateness of the selection, characteristics, and insertion technique of intravenous catheters in children with CHD with both univentricular and biventricular physiology.
Conclusion:
miniMAGIC-CHD provides evidence-based criteria for intravenous catheter selection for children with CHD.
The objective of this chapter is to introduce the University of Kentucky IR4TD Lean Systems Program (LSP) and the concept of “True Lean,” as well as to discuss what we have observed to be critical challenges (derailers) to the successful implementation of Toyota Production System-(TPS)-based principles within non-Toyota organizations. This learning stems from experience teaching, coaching, and facilitating lean implementation activities in a wide range of industries over the past twenty-five years. Participants in the LSP Lean Certification program have been sent by over 175 companies representing industries from healthcare, steel, glass, ceramics, textiles, automotive, railroads, aerospace, commercial aviation, fast food restaurants, and food processing manufacturers as well as government, education, and NGOs. This chapter shares data collected from our staff and clients in an effort to help understand the current condition of lean in industry today and the major challenges confronting successful lean implementations.
