Origen of Alexandria stands at the headwaters of the entire history of Gospel reading. In this study of the earliest extant Gospel commentaries, Samuel Johnson explores questions, often associated with modern Gospel criticism, that were already formative of the first moments of the Christian interpretative tradition. Origen's approach to the Gospels in fact arose from straightforward historical and literary critical judgments: the Gospel narratives interweave things that happened with things that did not. Origen discerned that the Gospels depict events in Jesus's life not merely as matters of historical fact, but also figuratively. He did not just interpret the Gospels allegorically. Johnson demonstrates that Origen believed the Gospel writers themselves were figurative readers of the life of Jesus. Origen thus found no contradiction between discerning the truth of the Christian Gospels and facing the critical challenges of their literary form and formation. Johnson's study shows how they constitute a single unified vision.
The incidence of facial palsy has been rising worldwide, with recent evidence emerging of links to COVID-19 infection. To date, guidance on cost-effective treatments is limited to medication (prednisolone). In terms of physical therapy, neuromuscular retraining (NMR) to restore balanced facial function has been most widely evaluated, but not in terms of cost effectiveness. The added value of telerehabilitation is unknown.
Methods
A multistage technology assessment was conducted, which included the following:
• a national survey of current therapy pathways in the UK and patients’ and clinicians’ views on the benefits and challenges of telerehabilitation;
• a systematic review of clinical effectiveness trials evaluating facial NMR therapy;
• calculation of long-term morbidity costs (national economic burden) based on incidence, patient recovery profiles, health-related quality of life, and national facial palsy treatment costs (valuation of clinical improvements in monetary terms was provided by a national Delphi panel); and
• evaluation of the cost effectiveness of telerehabilitation (remote monitoring wearables) added to current face-to-face NMR delivery.
Results
Nationally, approximately five percent of patients with facial palsy (17% of unresolved cases) are referred for facial NMR. The long-term economic burden associated with unresolved cases is estimated to range from GBP351 (EUR417) to GBP584 (EUR692) million, indicating substantial savings if long-term recovery can be improved. Medical treatment costs are GBP86.34 (EUR102) million per annual cohort, and physical and psychological therapy costs are GBP643,292 (EUR762,561). Economic modeling showed that telerehabilitation was cost effective, producing a health gain and a cost-saving of GBP468 (EUR555) per patient. If scaled to the national level for all patients who do not recover fully, an annual saving of GBP3.075 (EUR3.65) million is possible.
Conclusions
Economic modeling indicates that NMR could improve patient outcomes and reduce costs. The national survey demonstrated that access to NMR therapy services is limited, so introduction of telerehabilitation could improve access for currently underserved populations. Future clinical trials need to incorporate economic evaluations to help inform decision-making.
Non-clinical aspects of life, such as social, environmental, behavioral, psychological, and economic factors, what we call the sociome, play significant roles in shaping patient health and health outcomes. This paper introduces the Sociome Data Commons (SDC), a new research platform that enables large-scale data analysis for investigating such factors.
Methods:
This platform focuses on “hyper-local” data, i.e., at the neighborhood or point level, a geospatial scale of data not adequately considered in existing tools and projects. We enumerate key insights gained regarding data quality standards, data governance, and organizational structure for long-term project sustainability. A pilot use case investigating sociome factors associated with asthma exacerbations in children residing on the South Side of Chicago used machine learning and six SDC datasets.
Results:
The pilot use case reveals one dominant spatial cluster for asthma exacerbations and important roles of housing conditions and cost, proximity to Superfund pollution sites, urban flooding, violent crime, lack of insurance, and a poverty index.
Conclusion:
The SDC has been purposefully designed to support and encourage extension of the platform into new data sets as well as the continued development, refinement, and adoption of standards for dataset quality, dataset inclusion, metadata annotation, and data access/governance. The asthma pilot has served as the first driver use case and demonstrates promise for future investigation into the sociome and clinical outcomes. Additional projects will be selected, in part for their ability to exercise and grow the capacity of the SDC to meet its ambitious goals.
Vaccination against hepatitis B virus (HBV) is effective at preventing vertical transmission. Sierra Leone, Liberia, and Guinea are hyperendemic West African countries; yet, childhood vaccination coverage is suboptimal, and the determinants of incomplete vaccination are poorly understood. We analyzed national survey data (2018–2020) of children aged 4–35 months to assess complete HBV vaccination (receiving 3 doses of the pentavalent vaccine) and incomplete vaccination (receiving <3 doses). Statistical analysis was conducted using the complex sample command in SPSS (version 28). Multivariate logistic regression was used to identify determinants of incomplete immunization. Overall, 11,181 mothers were analyzed (4,846 from Sierra Leone, 2,788 from Liberia, and 3,547 from Guinea). Sierra Leone had the highest HBV childhood vaccination coverage (70.3%), followed by Liberia (64.6%) and Guinea (39.3%). Within countries, HBV vaccination coverage varied by socioeconomic characteristics and healthcare access. In multivariate regression analysis, factors that were significantly associated with incomplete vaccination in at least one country included sex of the child, Muslim mothers, lower household wealth index, <4 antenatal visits, home delivery, and distance to health facility vaccination (all p < 0.05). Understanding and addressing modifiable determinants of incomplete vaccination will be essential to help achieve the 2030 viral hepatitis elimination goals.
This article aims to explore the ethical issues arising from attempts to diversify genomic data and include individuals from underserved groups in studies exploring the relationship between genomics and health. We employed a qualitative synthesis design, combining data from three sources: 1) a rapid review of empirical articles published between 2000 and 2022 with a primary or secondary focus on diversifying genomic data, or the inclusion of underserved groups and ethical issues arising from this, 2) an expert workshop and 3) a narrative review. Using these three sources we found that ethical issues are interconnected across structural factors and research practices. Structural issues include failing to engage with the politics of knowledge production, existing inequities, and their effects on how harms and benefits of genomics are distributed. Issues related to research practices include a lack of reflexivity, exploitative dynamics and the failure to prioritise meaningful co-production. Ethical issues arise from both the structure and the practice of research, which can inhibit researcher and participant opportunities to diversify data in an ethical way. Diverse data are not ethical in and of themselves, and without being attentive to the social, historical and political contexts that shape the lives of potential participants, endeavours to diversify genomic data run the risk of worsening existing inequities. Efforts to construct more representative genomic datasets need to develop ethical approaches that are situated within wider attempts to make the enterprise of genomics more equitable.
Chater & Loewenstein have done a service to the field by raising the fundamental issue of how the political process distorts well-intentioned efforts at behavioral public policy. We connect this argument to broader research on government failure, particularly public choice theory in economics. We further suggest ways that behavioral research can help identify and mitigate such failures.
Whereas most commentators agree about the centrality of narratives in decision-making, the commentaries revealed little consensus about the nature of radical uncertainty. Here we consider thirteen objections to our views, including our characterization of the uncertain decision environment and associated cognitive, affective, and social processes. We conclude that under radical uncertainty, narratives rather than probabilities are the currency of thought.
OBJECTIVES/GOALS: Glioblastomas (GBMs) are heterogeneous, treatment-resistant tumors that are driven by populations of cancer stem cells (CSCs). In this study, we perform an epigenetic-focused functional genomics screen in GBM organoids and identify WDR5 as an essential epigenetic regulator in the SOX2-enriched, therapy resistant cancer stem cell niche. METHODS/STUDY POPULATION: Despite their importance for tumor growth, few molecular mechanisms critical for CSC population maintenance have been exploited for therapeutic development. We developed a spatially resolved loss-of-function screen in GBM patient-derived organoids to identify essential epigenetic regulators in the SOX2-enriched, therapy resistant niche. Our niche-specific screens identified WDR5, an H3K4 histone methyltransferase responsible for activating specific gene expression, as indispensable for GBM CSC growth and survival. RESULTS/ANTICIPATED RESULTS: In GBM CSC models, WDR5 inhibitors blocked WRAD complex assembly and reduced H3K4 trimethylation and expression of genes involved in CSC-relevant oncogenic pathways. H3K4me3 peaks lost with WDR5 inhibitor treatment occurred disproportionally on POU transcription factor motifs, required for stem cell maintenance and including the POU5F1(OCT4)::SOX2 motif. We incorporated a SOX2/OCT4 motif driven GFP reporter system into our CSC cell models and found that WDR5 inhibitor treatment resulted in dose-dependent silencing of stem cell reporter activity. Further, WDR5 inhibitor treatment altered the stem cell state, disrupting CSC in vitro growth and self-renewal as well as in vivo tumor growth. DISCUSSION/SIGNIFICANCE: Our results unveiled the role of WDR5 in maintaining the CSC state in GBM and provide a rationale for therapeutic development of WDR5 inhibitors for GBM and other advanced cancers. This conceptual and experimental framework can be applied to many cancers, and can unmask unique microenvironmental biology and rationally designed combination therapies.
Conviction Narrative Theory (CNT) is a theory of choice under radical uncertainty – situations where outcomes cannot be enumerated and probabilities cannot be assigned. Whereas most theories of choice assume that people rely on (potentially biased) probabilistic judgments, such theories cannot account for adaptive decision-making when probabilities cannot be assigned. CNT proposes that people use narratives – structured representations of causal, temporal, analogical, and valence relationships – rather than probabilities, as the currency of thought that unifies our sense-making and decision-making faculties. According to CNT, narratives arise from the interplay between individual cognition and the social environment, with reasoners adopting a narrative that feels “right” to explain the available data; using that narrative to imagine plausible futures; and affectively evaluating those imagined futures to make a choice. Evidence from many areas of the cognitive, behavioral, and social sciences supports this basic model, including lab experiments, interview studies, and econometric analyses. We identify 12 propositions to explain how the mental representations (narratives) interact with four inter-related processes (explanation, simulation, affective evaluation, and communication), examining the theoretical and empirical basis for each. We conclude by discussing how CNT can provide a common vocabulary for researchers studying everyday choices across areas of the decision sciences.
Statistical issues are prominent in Alzheimer’s disease (AD) clinical trials due to the enormous challenges in this disease. The complexity of the disease and intervention pathways challenge drug discovery efforts, but measurement and analysis complexities and subjective outcomes also interfere with successful drug development. Variability across disease stage, disease sub-types, comorbidities and concomitant treatments (between-subject), and non-equivalent forms, good and bad days, and rater inconsistencies (within-subject) increase the chance of failure. AD-specific statistical expertise is critical for success, in contrast to most disease areas that require less disease-specific statistical knowledge. Use of global statistical tests and composites, correcting for covariates, and model selection increase the chance of a clearly positive outcome for active treatments and a clearly negative outcome for inactive or harmful treatments.
The ancient city of Gabii—an Italian polity of the first millennium BC and a peer to early Rome—has often been presented as an example of urban decline, a counterpoint to Rome's rise from a collection of hilltop huts to a Mediterranean hegemon. Here the authors draw on the results from recent excavations at Gabii that challenge such simplistic models of urban history. Diachronic evidence documenting activity at the site over the course of 1400 years highlights shifting values and rhythms materialised in the maintenance, transformation and abandonment of different urban components. This complex picture of adaptation and resilience provides a model of ancient urbanism that calls into question outdated narratives of urban success and failure.
‘Group consultations/visits’ are described as providing shared medical appointments delivering a range of care options and education by clinicians while providing elements of patient choice, empowerment and peer support.
This innovative and cost effective model of care delivery was first conceived in the US and has been gaining a strong foothold in the UK since 2016, mainly limited to GP settings.
The project goal was to attempt to transfer the model into a mental health setting by developing and delivering a novel intervention, to improve health and wellbeing options in a CMHT population.
Method
A four session course was developed focussing on stress, sleep and nutrition. These chosen topics covered common significant challenges to patient health in psychiatry. Sessions were delivered to proactively address these important health related issues in a group visit setting.
Baseline and post intervention feedback including telephone interviews were conducted to evaluate the effectiveness of the intervention.
Result
The qualitative data and the positive feedback obtained from participants indicate the intervention was highly valued and deemed effective in promoting positive health and lifestyle changes. Participants valued the educational and co-production aspects as well as the social and peer support elements of the groups. They appreciated the level of access they had with the clinicians involved, to explore their health and wellbeing in more detail without being limited by the usual 30 minute clinic follow-up sessions.
The clinicians involved found the sessions rewarding and more engaging than most of routine 1:1 clinic sessions as they were able to spend quality time exploring important issues and not just educate the patients but also be educated by their questions and feedback about their lived experiences.
Conclusion
The project aim was met and we believe this intervention can be successfully incorporated into the identified service provision gap within the CMH T model. There is potential to build on and embed this innovation with roll-out to a wide range of service users in different settings.
In line with existing literature from GP settings, the consensus was that the amalgamated group visits/consultations model could be successfully modified to meet the needs of patients in the Mental Health arena who have a range of physical health and lifestyle concerns.
We planned to obtain more information about improvement in patient self-management but this was affected by the pandemic. However, we believe it is a cost effective and helpful innovation which warrants further promotion and evaluation.
Studies suggest that alcohol consumption and alcohol use disorders have distinct genetic backgrounds.
Methods
We examined whether polygenic risk scores (PRS) for consumption and problem subscales of the Alcohol Use Disorders Identification Test (AUDIT-C, AUDIT-P) in the UK Biobank (UKB; N = 121 630) correlate with alcohol outcomes in four independent samples: an ascertained cohort, the Collaborative Study on the Genetics of Alcoholism (COGA; N = 6850), and population-based cohorts: Avon Longitudinal Study of Parents and Children (ALSPAC; N = 5911), Generation Scotland (GS; N = 17 461), and an independent subset of UKB (N = 245 947). Regression models and survival analyses tested whether the PRS were associated with the alcohol-related outcomes.
Results
In COGA, AUDIT-P PRS was associated with alcohol dependence, AUD symptom count, maximum drinks (R2 = 0.47–0.68%, p = 2.0 × 10−8–1.0 × 10−10), and increased likelihood of onset of alcohol dependence (hazard ratio = 1.15, p = 4.7 × 10−8); AUDIT-C PRS was not an independent predictor of any phenotype. In ALSPAC, the AUDIT-C PRS was associated with alcohol dependence (R2 = 0.96%, p = 4.8 × 10−6). In GS, AUDIT-C PRS was a better predictor of weekly alcohol use (R2 = 0.27%, p = 5.5 × 10−11), while AUDIT-P PRS was more associated with problem drinking (R2 = 0.40%, p = 9.0 × 10−7). Lastly, AUDIT-P PRS was associated with ICD-based alcohol-related disorders in the UKB subset (R2 = 0.18%, p < 2.0 × 10−16).
Conclusions
AUDIT-P PRS was associated with a range of alcohol-related phenotypes across population-based and ascertained cohorts, while AUDIT-C PRS showed less utility in the ascertained cohort. We show that AUDIT-P is genetically correlated with both use and misuse and demonstrate the influence of ascertainment schemes on PRS analyses.
In the United Kingdom (UK), 23,000 people annually are diagnosed with facial palsy (acute onset facial paralysis). For nearly one third this will result in a permanent disability, including in some the inability to smile. In addition to initial pharmacological therapy, guidelines recommend tailored facial exercise (TFE) therapy repeated every day. However, not all patients are currently able to access such specialist physical therapy. ‘Smart specs’ (using miniaturized sensors in the frames to measure facial movement) are currently being developed. Linked to a smartphone, these could allow people to practice TFEs discreetly, provide immediate feedback, and supply data on outcomes to the patient and their clinician.
Methods:
Modelling of introduction of Facial Remote Activity Monitoring Eyewear (FRAME) into treatment pathways for patients with facial palsy. This included: (i) review on effectiveness of TFE therapy; (ii) national surveys (medical staff, facial therapy specialists and patients) to gather data on access to TFE therapy; (iii) Delphi Exercise to identify consensus on key outcome measures; and, (iv) economic modelling to estimate cost-effectiveness and determine a range of acceptable costs for the technology. In parallel, research to examine target markets to inform product development, and production of integral commercialization plan.
Results:
Searches short-listed ten studies to add to the three included in the 2011 Cochrane review. Surveys indicate approximately thirteen percent of eligible UK patients access personalized TFE therapy. Estimated annual expenditure on hospital treatments for facial palsy patients is currently >GBP 80 million (>USD 106 million) compared with <GBP 0.5 million (<USD 0.66 million) on TFE therapy. Patients with permanent defects can suffer a loss of up to two quality-adjusted life years (QALYs).
Conclusions:
Findings from this study, particularly in relation to costs and benefits, will inform the design of a subsequent randomized controlled trial. A novel wearable technology could make a major difference to people's lives, as well as generating potential efficiencies for healthcare.
Zero-sum thinking and aversion to trade pervade our society, yet fly in the face of everyday experience and the consensus of economists. Boyer & Petersen's (B&P's) evolutionary model invokes coalitional psychology to explain these puzzling intuitions. I raise several empirical challenges to this explanation, proposing two alternative mechanisms – intuitive mercantilism (assigning value to money rather than goods) and errors in perspective-taking.
Professional money management appears to require little skill, yet its practitioners command astronomical salaries. Singh's theory of shamanism provides one possible explanation: Financial professionals are the shamans of the global economy. They cultivate the perception of superhuman traits, maintain grueling initiation rituals, and rely on esoteric divination rituals. An anthropological view of markets can usefully supplement economic and psychological approaches.
Caregiver satisfaction and experience surveys help health professionals to understand, measure, and improve the quality of care provided for patients and their families.
Objective:
Our aim was to explore caregiver perceptions of the care received from Australian specialist palliative care services.
Method:
Caregivers of patients receiving palliative care in services registered with Australia's Palliative Care Outcomes Collaboration were invited to participate in a caregiver survey. The survey included the FAMCARE–2 and four items from the Ongoing Needs Identification: Caregiver Profile questionnaire.
Results:
Surveys were completed by 1,592 caregivers from 49 services. Most respondents reported high satisfaction and positive experiences. Caregivers receiving care from community-based palliative care teams were less satisfied with the management of physical symptoms and comfort (odds ratio [OR] = 0.29; 95% confidence interval [CI95%] = 0.14, 0.59), with patient psychological care (OR = 0.56; CI95% = 0.32, 0.98), and with family support (OR = 0.52; CI95% = 0.35, 0.77) than caregivers of patients in an inpatient setting. If aged over 60 years, caregivers were less likely to have their information needs met regarding available support services (OR = 0.98; CI95% = 0.97, 0.98) and carer payments (OR = 0.99; CI95% = 0.98, 1.00). Also, caregivers were less likely to receive adequate information about carer payments if located in an outer regional area (OR = 0.41; CI95% = 0.25, 0.64). With practical training, caregivers receiving care from community services reported inadequate information provision to support them in caring for patients (OR = 0.60; CI95% = 0.45, 0.81).
Significance of Results:
While our study identified caregivers as having positive and satisfactory experiences across all domains of care, there is room for improvement in the delivery of palliative care across symptom management, as well as patient and caregiver support, especially in community settings. Caregiver surveys can facilitate the identification and evaluation of both patients' and caregivers' experiences, satisfaction, distress, and unmet needs.
