Abstract

Summary: Background: An episode of acute ulcerative colitis (UC) represents an important watershed moment in a patient's disease course. Aims: To derive a personalised algorithm for identifying patients at high risk of corticosteroid non‐response from variables available at hospital presentation using a large prospectively collected acute UC patient database and machine learning‐based techniques. Methods: We analysed data from 682 consecutive presentations of acute UC. We used an Akaike information criterion‐based elastic net model to select variables based on the 419 earliest presentations of acute UC (1996–2017). We constructed two risk‐scoring algorithms, with and without utilising additional endoscopic variables, using logistic regression models. We validated these risk scores on separate cohorts of 181 (2018–2022) and 82 (2015–2022) acute UC presentations. Results: The partial risk of rescue (ROR) score included the admission indices of oral corticosteroid treatment, bowel frequency ≥6/24 h, albumin, CRP ≥12 mg/mL and log10CRP. The full ROR score incorporates the same variables with the addition of the Mayo endoscopic subscore and disease extent. The AUCs in the main validation cohort were 0.76 (95% CI: 0.69–0.83) and 0.78 (95% CI: 0.71–0.85) for the partial and full ROR scores, respectively. Conclusions: These pragmatic personalised risk scores (available at www.severecolitis.com) have comparably strong performance characteristics and usability enabling the identification of individuals at high risk of corticosteroid non‐response before or after endoscopic assessment. The ROR scores have the potential to challenge conventional acute UC treatment paradigms by identifying patients who may benefit from early rescue therapy or participation in relevant clinical trials.

Abstract

Previous research has provided strong evidence that speech patterns can help to distinguish between people with early stage neurodegenerative disorders (ND) and healthy controls. This study examined speech patterns in responses to questions asked by an intelligent virtual agent (IVA): a talking head on a computer which asks pre-recorded questions. The study investigated whether measures of response length, speech rate and pausing in responses to questions asked by an IVA help to distinguish between healthy control participants and people diagnosed with Mild Cognitive Impairment (MCI) or Alzheimer's disease (AD). The study also considered whether those measures can further help to distinguish between people with MCI, people with AD, and healthy control participants (HC). There were 38 people with ND (31 people with MCI, 7 people with AD) and 26 HC. All interactions took place in English. People with MCI spoke fewer words compared to HC, and people with AD and people with MCI spoke for less time than HC. People with AD spoke at a slower rate than people with MCI and HC. There were significant differences across all three groups for the proportion of time spent pausing and the average pause duration: silent pauses make up the greatest proportion of responses from people with AD, who also have the longest average silent pause duration, followed by people with MCI then HC. Therefore, the study demonstrates the potential of an IVA as a method for collecting data showing patterns which can help to distinguish between diagnostic groups. [ABSTRACT FROM AUTHOR]

9. An uncooperative community : revisiting water privatisation and commoditisation in England and Wales

Abstract

Since its inception in 1989, the private water sector of England and Wales has been enlisted as a centrepiece in debates concerning the merits of privatisation. Advocates point to increased environmental performance and increased investment. Critics note a significant retraction of the early free market aspirations and increasingly prescriptive regulation. However, market mechanisms and liberalisation are once again being emphasised in policy, reigniting the debate surrounding the commoditisation of water. This thesis engages directly and critically with Karen Bakker's 'Uncooperative Commodity' approach to the 'reregulation' of the industry, arguing its tenants must be adapted to accommodate these recent developments. While Bakker's earlier accounts of the reregulation of the water industry placed a great emphasis on the geography and biophysical properties of water, later work by both her and her contemporaries have developed more refined and socialised models of how water and society interact to produce temporary regularities in the material world. This thesis argues that an appropriate means of developing Bakker's original thesis would be a greater focus on socio-historical context when exploring the materiality of water, and hence the degree to which water may be transformed into a private commodity. Bob Jessop's Strategic Relational Approach (Jessop 2008) is deployed as a means of describing and relating: (1) the degree to which research can identify underlying mechanisms which govern the outcomes of attempts to commoditise water under capitalist modes of production, (2) the role of the state and politics in flanking or supporting the commoditisation of water and (3) the role of existing discursive-institutional structures in introducing path-dependencies and uneven power geometries which in turn effect the outcomes of collective action towards the commoditisation of water. The thesis documents historical developments in English and Welsh resource planning, regulation, and policy from 1945 to 2012 in order to explain the current structure of the industry, its response to water scarcity, and the origins of the current reform programme. It then focuses on the conflicts and tensions between actors in the industry generated by the current reform programme and their role in affecting the degree of success of the programme itself.

The integration of 300 mK semiconductor bolometers and 4 K hot-electron bolometers with commercial pulse tube cryocooler (PTC) systems has been investigated. The process also involved the integration of a two-stage 4He-3He adsorption refrigerator with the PTC to produce a cryogen free sub-Kelvin system. Thermometry electronics with an onboard computer and an internet interface have been developed that allow for remote and/or automatic operation. Methods to reduce excess noise seen in the 300 mK bolometer have been investigated to demonstrate the possibility of using high sensitivity bolometric detectors in this system for astrophysics and Earth observation instruments. In order to minimise the microphonic induced noise and thermal fluctuations from the pulse tube operation an AC biasing circuit was used. The origin of excess noise components in the bolometer readout have been identified and quantified as a function of both mechanical and electrical configurations of the cold components. With the optimum configuration thermal fluctuation noise, rather than microphonic induced noise dominates, reducing the bolometer sensitivity by approximately two times compared to the same device operated in a liquid helium cooled cryostat. Clearly the performance could be improved by increasing the thermal isolation of the sorption refrigerator from the pulse tube temperature oscillations. The hot-electron bolometer behaved nominally up to 6 kHz when operated in the cryogen free cryostat. Dynamic audio frequency noise deteriorated the detector's performance above 6 kHz and has been attributed to the movement of the helium gas through the PTC's valves and orifices during its thermodynamic cycle. Restrictions of the signal analyser mean that it is unclear whether this microphonic noise is present above 1 MHz.

Abstract

The solubility of uranium (IV) oxide, UO2, was investigated. Uranium (VI) was reduced to uranium (IV) using sodium dithionite and iron granules at high pH (NaOH). A solubility enhancement of UO2 in the presence of Boom clay humic acid (BCHA) was found to be approximately one order of magnitude, where the solubility of UO2 (10-9 to 10-8 mol dm-3) was increased to 10-7 mol dm-3 by BCHA. The solubility product (Ksp) of aqueous U(OH)4 and stability constant (β141) for BCHA-U(OH)4 were calculated from experimental data using a novel approach utilising the side reaction coefficient theory ('A' term). A log Ksp value of -54.51 for U(OH)4, and a log β141 value of 51.36 for BCHA-U(OH)4 were calculated.

19. Phonetic Variation and Interactional Contingencies in Simultaneous Responses

Author

Walker, Gareth

Abstract

An auspicious but unexplored environment for studying phonetic variation in naturalistic interaction is where two or more participants say the same thing at the same time. Working with a core dataset built from the multimodal Augmented Multi-party Interaction corpus, the principles of conversation analysis were followed to analyze the sequential organization of the talk and to explain the phonetic variation observed. Acoustic divergence and equivalence between simultaneous responses are described. Phonetic features discussed include duration and timing, pitch, loudness, and phonation type. The interactional factors that explain the acoustic divergences are established through turn-by-turn analysis and consideration of gaze direction and other visible features. It is argued that any research on phonetic variation in naturalistic talk that disregards the local organization of interaction will always be incomplete.

Abstract

Background: Asking patients who have been referred to memory clinics open questions about recent events has been shown to have diagnostic relevance. Method: We use conversation analysis to look at responses to questions about recent events. The interviewees are healthy control (HC) participants, people with mild cognitive impairment (MCI), and people with Alzheimer's disease (AD). Results: We show differences among the groups' use of claims of memory problems, self-directed questions, and well-prefacing. Healthy control participants produce more talk in response to all of these, while people with MCI and AD either do not, or do so in demonstrably different ways from both HC participants and each other. Discussion/conclusion: Healthy control participants are both willing and able to 'show off' their memory, while people with AD are willing but generally unable to do so. People with MCI, in contrast, display themselves as both unwilling and unable to engage with the agent's questions as tests of memory. [ABSTRACT FROM AUTHOR]

24. Coordination and Interpretation of Vocal and Visible Resources: 'Trail-Off' Conjunctions

Author

Walker, Gareth

Abstract

The empirical focus of this paper is a conversational turn-taking phenomenon in which conjunctions produced immediately after a point of possible syntactic and pragmatic completion are treated by co-participants as points of possible completion and transition relevance. The data for this study are audio-video recordings of 5 unscripted face-to-face interactions involving native speakers of US English, yielding 28 "trail-off" conjunctions. Detailed sequential analysis of talk is combined with analysis of visible features (including gaze, posture, gesture and involvement with material objects) and technical phonetic analysis. A range of phonetic and visible features are shown to regularly co-occur in the production of "trail-off" conjunctions. These features distinguish them from other conjunctions followed by the cessation of talk. (Contains 10 figures, 1 table and 9 notes.)

Abstract

Data on patients with inflammatory bowel diseases (IBD) who have had 2019 novel coronavirus (SARS-CoV-2) disease (COVID-19) are needed.To report the clinical characteristics, including gastrointestinal symptoms, of COVID-19 in IBD patients, and to assess the risk of COVID-19 in IBD.This case series included consecutive IBD patients with laboratory-confirmed COVID-19. Age-adjusted cumulative incidences were compared with the general population in the Madrid region.Through April 8, 12 of 1918 IBD patients were diagnosed with COVID-19. The average age was 52 years, 75% of the patients were female and 58.3% had Crohn's disease. Seven patients (58%) were on maintenance treatment with immunomodulators/biologics, of these four with combined therapy (33%). Eight patients (66%) required hospitalisation (one intensive care unit admission, and two deaths), and four patients were isolated at home. Nine patients had diarrhoea ranging between 4 and 10 loose stools per day (mean 5.4, SD 1.6). In five patients (42%) diarrhoea was a presenting symptom. In two patients, diarrhoea was the only symptom at debut. Cumulative incidence of COVID-19 was 6.2 per 1000 IBD patients. IBD patients had a lower adjusted incidence ratio of COVID-19 (OR 0.74, 95% CI 0.70-0.77; P 0.001), and a similar associated mortality ratio (OR 0.95, 95% CI: 0.84-1.06; P = 0.36), compared with the general population.IBD patients do not have an increased risk of COVID-19 and associated mortality compared with the general population. In many IBD patients, diarrhoea was a presenting symptom, and sometimes, was the only symptom at onset of COVID-19.

Abstract

Contains fulltext : 288040.pdf (Publisher’s version ) (Open Access) BACKGROUND: Anti-drug antibodies are associated with treatment failure to anti-TNF agents in patients with inflammatory bowel disease (IBD). AIM: To assess whether immunogenicity to a patient's first anti-TNF agent would be associated with immunogenicity to the second, irrespective of drug sequence METHODS: We conducted a UK-wide, multicentre, retrospective cohort study to report rates of immunogenicity and treatment failure of second anti-TNF therapies in 1058 patients with IBD who underwent therapeutic drug monitoring for both infliximab and adalimumab. The primary outcome was immunogenicity to the second anti-TNF agent, defined at any timepoint as an anti-TNF antibody concentration ≥9 AU/ml for infliximab and ≥6 AU/ml for adalimumab. RESULTS: In patients treated with infliximab and then adalimumab, those who developed antibodies to infliximab were more likely to develop antibodies to adalimumab, than patients who did not develop antibodies to infliximab (OR 1.99, 95%CI 1.27-3.20, p = 0.002). Similarly, in patients treated with adalimumab and then infliximab, immunogenicity to adalimumab was associated with subsequent immunogenicity to infliximab (OR 2.63, 95%CI 1.46-4.80, p

Abstract

IntroductionAcute severe ulcerative colitis (ASUC) traditionally requires inpatient hospital management for intravenous therapies and/or colectomy. Ambulatory ASUC care has not yet been evaluated in large cohorts.AimsWe used data from PROTECT, a UK multicentre observational COVID-19 inflammatory bowel disease study, to report the extent, safety and effectiveness of ASUC ambulatory pathways.MethodsAdults (≥18 years old) meeting Truelove and Witts criteria between 1 January 2019–1 June 2019 and 1 March 2020–30 June 2020 were recruited to PROTECT. We used demographic, disease phenotype, treatment outcomes and 3-month follow-up data. Primary outcome was rate of colectomy during the index ASUC episode. Secondary outcomes included corticosteroid response, time to and rate of rescue or primary induction therapy, response to rescue or primary induction therapy, time to colectomy, mortality, duration of inpatient treatment and hospital readmission and colectomy within 3 months of index flare. We compared outcomes in three cohorts: (1) patients treated entirely in inpatient setting; ambulatory patients subdivided into; (2) patients managed as ambulatory from diagnosis and (3) patients hospitalised and subsequently discharged to ambulatory care for continued intravenous steroids.Results37% (22/60) participating hospitals used ambulatory pathways. Of 764 eligible patients, 695 (91%) patients received entirely inpatient care, 15 (2%) patients were managed as ambulatory from diagnosis and 54 (7%) patients were discharged to ambulatory pathways. Aside from younger age in patients treated as ambulatory from diagnosis, no significant differences in disease or patient phenotype were observed. The rate of colectomy (15.0% (104/695) vs 13.3% (2/15) vs 13.0% (7/54), respectively, p=0.96) and secondary outcomes were similar among all three cohorts. Stool culture and flexible sigmoidoscopy were less frequently performed in ambulatory cohorts. Forty per cent of patients treated as ambulatory from diagnosis required subsequent hospital admission.ConclusionsIn a post hoc analysis of one of the largest ASUC cohorts collected to date, we report an emerging UK ambulatory practice which challenges treatment paradigms. However, our analysis remains underpowered to detect key outcome measures and further studies exploring clinical and cost-effectiveness as well as patient and physician acceptability are needed.Trial registration numberNCT04411784.

Abstract

Summary: Background: The COVID‐19 pandemic offered a unique opportunity to understand inflammatory bowel disease (IBD) management during unexpected disruption. This could help to guide practice overall. Aims: To compare prescribing behaviour for IBD flares and outcomes during the early pandemic with pre‐pandemic findings Methods: We performed an observational cohort study comprising patients who contacted IBD teams for symptomatic flares between March and June 2020 in 60 National Health Service trusts in the United Kingdom. Data were compared with a pre‐pandemic cohort after propensity‐matching for age and physician global assessment of disease activity. Results: We included 1864 patients in each of the pandemic and pre‐pandemic cohorts. The principal findings were reduced systemic corticosteroid prescription during the pandemic in Crohn's disease (prednisolone: pandemic 26.5% vs. 37.1%; p < 0.001) and ulcerative colitis (UC) (prednisolone: pandemic 33.5% vs. 40.7%, p < 0.001), with increases in poorly bioavailable oral corticosteroids in Crohn's (pandemic 15.6% vs. 6.8%; p < 0.001) and UC (pandemic 11.8% vs. 5.2%; p < 0.001). Ustekinumab (Crohn's and UC) and vedolizumab (UC) treatment also significantly increased. Three‐month steroid‐free remission in each period was similar in Crohn's (pandemic 28.4% vs. 32.1%; p = 0.17) and UC (pandemic 36.4% vs. 40.2%; p = 0.095). Patients experiencing a flare and suspected COVID‐19 were more likely to have moderately‐to‐severely active disease at 3 months than those with a flare alone. Conclusions: Despite treatment adaptations during the pandemic, steroid‐free outcomes were comparable with pre‐pandemic levels, although concurrent flare and suspected COVID‐19 caused worse outcomes. These findings have implications for IBD management during future pandemics and for standard practice. [ABSTRACT FROM AUTHOR]
