    Finding effective methods to guide novice clinical education researchers to interrogate their beliefs about paradigms can be a challenge for education practitioners leading training in this area. We share why we believe it is important for healthcare educators to build an understanding of research paradigms and how we demystified the teaching of philosophy and the ‘-ologies’ of research, to support novice researchers in their development. Through our use of gamification techniques based on Socratic questioning, we show how educators may be supported in the process of deconstructing their research project’s paradigm into its component parts. This comprises key questions about coherent alignment of their ontologies, epistemologies, and methods, and encouraging researchers to think openly about their assumptions to improve the conduct of research, particularly in the qualitative field

    Gender differences and mask wearing: an observational study on a University campus and a mini-meta-analysis

    Research informed by evolutionary theory has suggested that, all else being equal, men are expected to take greater risks than women. This has been evidenced in a range of domains, including health prevention behaviours. In this study, gender differences in mask wearing were recorded at three locations on a University campus (n = 1,435). Logistic regression and Bayes Factor analyses demonstrated that the data do not support a gender difference in mask wearing. This led us to supplement our findings with a mini-meta-analyis, synthesising the gender difference reported in ten papers (n = 73,493) observing mask wearing during the COVID-19 pandemic. This analysis is supportive of a weak effect whereby women are more inclined to wear a mask than men (OR = 1.54, 95 CI = 1.26 to 1.88). However, the mini-meta-analysis also suggested a considerable amount of heterogeneity. Our research calls for further work assessing the factors explaining this heterogeneity in the observed gender difference in mask wearing

    Purpose We assessed the impact of mHealth on Pap test screening uptake and also determined the factors that affect screening uptake among women in Lagos, Nigeria. Materials and Methods A randomized controlled trial was carried out among women in two tertiary health institutions in Lagos, Nigeria, between July 2020 and March 2021. Participants were randomly assigned to either a text message (mHealth) intervention or usual care arm. The main study outcome was the uptake of Pap smear testing within 6 months of enrollment in the study. We tested the associations between two groups of continuous variables using the unpooled independent-sample t-test (normal distribution) and that of two groups of categorical variables with the chi-square (χ2) test. Using a multinomial logistic regression model, we adjusted for relevant sociodemographic and clinical predictors of uptake of Pap smear screening. Statistical significance was defined as P < .05. Results There was a significantly higher rate of uptake of Pap smear screening among women in the mHealth arm compared with those in the usual care arm (51.0% v 35.7%, P = .031). Following adjustment in the final multivariate model, level of income (odds ratio [OR] = 5.13, 95% CI, 1.55 to 16.95), awareness of Pap smear (OR = 16.26; 95% CI, 2.49 to 76.64), General Outpatient clinic attendance, and introduction of mHealth intervention during follow-up (OR = 4.36; 95% CI, 1.44 to 13.22) were the independent predictors of Pap smear uptake. Conclusion The use of mHealth technologies intervention via short-text message services is a feasible solution for cervical cancer prevention in low- and middle-income countries, and thus, the widespread use of mHealth services by health care providers and policymakers could contribute to the implementation of cervical cancer prevention services in Nigeria and in the settings of other low- and middle-income countries

    Exploring the Contextual Assumptions, Interventions, and Outcomes of Digital Advance Care Planning Systems: A Theory of Change Approach to Understand Implementation and Evaluation

    Get PDF
    Background: Digital advance care planning systems are used internationally to document and share patients’ wishes and preferences to inform care delivery. However, their use is impeded by a limited understanding of factors influencing implementation and evaluation. Aim: To develop mid-range programme theory to account for technological, infrastructure and human factor influences on digital advance care planning systems. Design: Exploratory qualitative research design incorporating Theory of Change workshops that explored contextual assumptions affecting digital advance care planning in practice. A mid-range programme theory was developed through thematic framework analysis using the Non-adoption, Abandonment, Scale-up, Spread, and Sustainability (NASSS) framework, generating a conceptual model depicting contextual assumptions, interventions and outcomes influencing implementation. Participants: 38 participants (16 from London, 14 from West Yorkshire, and eight online) including patients, carers, and health and care professionals (including those with commissioning responsibilities). Results: A conceptual model was generated depicting five distinct components relating to digital advance care planning system use: (sociocultural, technical, and structural prerequisites; recognition of the clinical need for conversation; having conversations and documenting decisions; accessing, actioning, and amending; and using data to support evaluation, use, and implementation). There were differences and uncertainty relating to what digital advance care planning systems are, who they are for, and how they should be evaluated. Conclusions: Digital advance care planning lacks shared beliefs and practices, despite these being essential for complex technology implementation. Our mid-range programme theory can guide their further development and application by considering technological, infrastructure and human factor influences to optimise their implementation

    A small-molecule PI3Kα activator for cardioprotection and neuroregeneration

    Harnessing the potential beneficial effects of kinase signalling through the generation of direct kinase activators remains an underexplored area of drug development1,2,3,4,5. This also applies to the PI3K signalling pathway, which has been extensively targeted by inhibitors for conditions with PI3K overactivation, such as cancer and immune dysregulation. Here we report the discovery of UCL-TRO-1938 (referred to as 1938 hereon), a small-molecule activator of the PI3Kα isoform, a crucial effector of growth factor signalling. 1938 allosterically activates PI3Kα through a distinct mechanism by enhancing multiple steps of the PI3Kα catalytic cycle and causes both local and global conformational changes in the PI3Kα structure. This compound is selective for PI3Kα over other PI3K isoforms and multiple protein and lipid kinases. It transiently activates PI3K signalling in all rodent and human cells tested, resulting in cellular responses such as proliferation and neurite outgrowth. In rodent models, acute treatment with 1938 provides cardioprotection from ischaemia–reperfusion injury and, after local administration, enhances nerve regeneration following nerve crush. This study identifies a chemical tool to directly probe the PI3Kα signalling pathway and a new approach to modulate PI3K activity, widening the therapeutic potential of targeting these enzymes through short-term activation for tissue protection and regeneration. Our findings illustrate the potential of activating kinases for therapeutic benefit, a currently largely untapped area of drug development

    Early ultrasound surveillance of newly-created haemodialysis arteriovenous fistula

    IntroductionWe assess if ultrasound surveillance of newly-created arteriovenous fistulas (AVFs) can predict nonmaturation sufficiently reliably to justify randomized controlled trial (RCT) evaluation of ultrasound-directed salvage intervention.MethodsConsenting adults underwent blinded fortnightly ultrasound scanning of their AVF after creation, with scan characteristics that predicted AVF nonmaturation identified by logistic regression modeling.ResultsOf 333 AVFs created, 65.8% matured by 10 weeks. Serial scanning revealed that maturation occurred rapidly, whereas consistently lower fistula flow rates and venous diameters were observed in those that did not mature. Wrist and elbow AVF nonmaturation could be optimally modeled from week 4 ultrasound parameters alone, but with only moderate positive predictive values (PPVs) (wrist, 60.6% [95% confidence interval, CI: 43.9–77.3]; elbow, 66.7% [48.9–84.4]). Moreover, 40 (70.2%) of the 57 AVFs that thrombosed by week 10 had already failed by the week 4 scan, thus limiting the potential of salvage procedures initiated by that scan’s findings to alter overall maturation rates. Modeling of the early ultrasound characteristics could also predict primary patency failure at 6 months; however, that model performed poorly at predicting assisted primary failure (those AVFs that failed despite a salvage attempt), partly because patency of at-risk AVFs was maintained by successful salvage performed without recourse to the early scan data.ConclusionEarly ultrasound surveillance may predict fistula maturation, but is likely, at best, to result in only very modest improvements in fistula patency. Power calculations suggest that an impractically large number of participants (>1700) would be required for formal RCT evaluation
