Introduction: A secondary loss of response (LOR) to infliximab (IFX) therapy for inflammatory bowel disease (IBD) is typically associated with low IFX trough levels, often with high levels of neutralizing antibodies to IFX (ATI). A small subset of patients on long-term therapy experience a “nonimmune” LOR, without ATI and with desired IFX trough levels ≥5 μg/mL, regarded as a LOR to the mechanism of action of IFX. However, this currently accepted IFX goal level is largely derived from observations of patients within the first year of therapy and may not apply to those on treatment beyond 1 year. Methods: Retrospective review of all IBD patients receiving IFX infusions for ≥12 months with at least 1 IFX trough and ATI measurement beyond 12 months was conducted. Chart review of all patients with absent ATI and an IFX trough ≥5 μg/mL classifies as LOR versus non-LOR based on physician assessment, with a comparison of IFX troughs between the two groups. Results: Of 167 patients using IFX ≥12 months, 13 (7.8%) experienced a nonimmune secondary LOR. The mean duration of IFX use was over 3 years for both LOR and non-LOR patients. The mean IFX trough for those with LOR was greater than for those without LOR, 18.5 μg/mL versus 13.1 μg/mL, p = 0.110. Conclusion: Our results did not demonstrate lower IFX levels among patients experiencing secondary nonimmune LOR on long-term therapy. Our results do not redefine the therapeutic IFX goal levels for those patients on long-term therapy and suggest that underdosing of IFX is not the cause of secondary LOR.

Uncertainty quantification (UQ) is a well-established category of methods to estimate the effect of parameter variations on a quantity of interest based on a solid mathematical foundation. In the wind energy field most UQ studies focus on the sensitivity of turbine loads. This article presents a framework, wrapped around a modern Python UQ library, to analyze the impact of uncertain turbine properties on aeroelastic stability. The UQ methodology applies a polynomial chaos expansion surrogate model. A comparison is made between different wind turbine simulation tools on the engineering model level (alaska/Wind, Bladed, HAWC2/HAWCStab2, and Simpack). Two case studies are used to demonstrate the effectiveness of the method to analyze the sensitivity of the aeroelastic damping of an unstable turbine mode to variations of structural blade cross-section parameters. The code-to-code comparison shows good agreement between the simulation tools for the reference model, but also significant differences in the sensitivities.

Direct fabrication of pure metallic nanostructures is one of the main aims of focused electron beam-induced deposition (FEBID). It was recently achieved for gold deposits by the co-injection of a water precursor and the gold precursor Au(tfac)Me2. In this work results are reported, using the same approach, on a different gold precursor, Au(acac)Me2, as well as the frequently used platinum precursor MeCpPtMe3. As a water precursor MgSO4·7H2O was used. The purification during deposition led to a decrease of the carbon-to-gold ratio (in atom %) from 2.8 to 0.5 and a decrease of the carbon-to-platinum ratio (in atom %) from 6–7 to 0.2. The purification was done in a regular scanning electron microscope using commercially available components and chemicals, which paves the way for a broader application of direct etching-assisted FEBID to obtain pure metallic structures.

Abstract Background The ongoing global crisis of Higher Education (HE) institutions during the post-COVID-19 pandemic period has increased the likelihood of enduring psychological stressors for staff. This study aimed to identify factors associated with job insecurity, burnout, psychological distress and coping amongst staff working at HE institutions globally. Methods An anonymous cross-sectional study was conducted in 2023 with staff at HE institutions across 16 countries. Job insecurity was measured using the Job Insecurity Scale (JIS), burnout using the Perceived Burnout measure question, psychological distress using the Kessler Psychological Distress Scale (K10), and coping using the Brief Resilient Coping Scale. Multivariable logistic regression with a stepwise variable selection method was used to identify associations. Results A total of 2,353 staff participated; the mean age (± SD) was 43(± 10) years and 61% were females. Most staff (85%) did not feel job insecurity, one-third (29%) perceived burnout in their jobs, more than two-thirds (73%) experienced moderate to very high levels of psychological distress, and more than half (58%) exhibited medium to high resilient coping. Perceived job insecurity was associated with staff working part-time [Adjusted Odds Ratio 1.53 (95% Confidence Intervals 1.15–2.02)], having an academic appointment [2.45 (1.78–3.27)], having multiple co-morbidities [1.86 (1.41–2.48)], perceived burnout [1.99 (1.54–2.56)] and moderate to very high level of psychological distress [1.68 (1.18–2.39)]. Perceived burnout was associated with being female [1.35 (1.12–1.63)], having multiple co-morbidities [1.53 (1.20–1.97)], perceived job insecurity [1.99 (1.55–2.57)], and moderate to very high levels of psychological distress [3.23 (2.42–4.30)]. Staff with multiple co-morbidities [1.46 (1.11–1.92)], mental health issues [2.73 (1.79–4.15)], perceived job insecurity [1.61 (1.13–2.30)], and perceived burnout [3.22 (2.41–4.31)] were associated with moderate to very high levels of psychological distress. Staff who perceived their mental health as good to excellent [3.36 (2.69–4.19)] were more likely to have medium to high resilient coping. Conclusions Factors identified in this study should be considered in reviewing and updating current support strategies for staff at HE institutions across all countries to reduce stress and burnout and improve wellbeing.

IntroductionEntering higher education (HE) is one of the most significant transitions in a student’s life and is negatively impacted by any disparity between expectation and initial experience when joining their course.MethodThe current study explored how the students’ experiences of learning and teaching practices in their previous educational environment influenced their expectations and initial experiences of HE. The study adopted a mixed methods approach, initially surveying 69 students concerning their previous educational experiences, expectations and experiences of HE. Informed by the questions in the survey, two semi-structured focus groups comprising a total of 6 students were completed and analysed using inductive thematic analysis.Results and discussionThe current research identified specific challenges students face as they transition into HE, often resulting in an initial culture shock as that adapt to their new learning environment. These challenges are, to some extent, a consequence of their previous learning environment. Whilst expectations of HE were cultivated in their previous educational environment, they were not always accurate and resulted in a mismatch between expectation and reality of HE. This article identifies what may be missing for a student as they transition from further education into HE, and explores some of the opportunities HE faces in addressing these deficits.

BackgroundSchistosomiasis is caused by infection with parasitic Schistosoma worms and affects more than 250 million people globally. The detection of schistosome derived circulating cathodic and anodic antigens (CCA and CAA) has proven highly valuable for detecting active Schistosoma infections, causing both intestinal and urinary schistosomiasis.AimThe combined detection of CCA and CAA was explored to improve accuracy in detecting Schistosoma infections.MethodsParallel detection of CCA and CAA was performed on two banked sample sets with matching serum and urine samples from Schistosoma mansoni (Sm) and S. haematobium (Sh) infected individuals using the non-concentration based lateral flow (LF) test comprising the sensitive luminescent up-converting reporter particle (UCP) technology.ResultsParallel detection of CCA and CAA increased the positivity rate for detecting both Sm and Sh infections compared to the detection of either antigen separately, demonstrating the added value of detecting both antigens in a single sample to confirm diagnosis, independent from the Schistosoma species. Significantly higher CCA concentrations in urine were observed in Sm infected individuals compared to Sh infected individuals, while serum CCA-concentrations were similar between species. CAA concentrations were higher in serum compared to those in urine, irrespective of species. When exploring the relationship of CCA and CAA in urine, the CCA/CAA ratio in Sm infected individuals was significantly higher than in Sh infected individuals, while no differences were observed in serum.Discussion and conclusionParallel detection of CCA and CAA via the UCP-LF platform showed added diagnostic value through an increased positivity rate for the detection of Sm and Sh infections, compared to only detecting either of the antigens. The combined and quantitative detection of CCA and CAA is indicative for identifying the infecting species, but needs further exploration.

Research in marketing, psychology, economics, and decision making has long examined what people choose, when people choose, and why people choose. But almost no research has examined how long people consume their choices. Here, we examined an asymmetry between choosing an option and consuming it. Under the aegis of nudges, we conducted two randomized longitudinal experiments on how long people consumed a choice that was incentivized vis-à-vis a decoy effect, default effect, and compromise effect. We found that these nudges influenced choosing and consuming in opposite directions: Participants were more likely to choose the nudged option; however, they consumed it less compared to participants who chose an identical non-nudged option. Our research thus demonstrates that nudges could lead people to consume a nudged option less after choosing it, illuminating the potential for future research to examine the unexplored area of longitudinal, post-acquisition, post-nudge effects.

Abstract In contrast to acute diarrhoea, the aetiology of persistent digestive disorders (≥ 14 days) is poorly understood in low-resource settings and conventional diagnostic approaches lack accuracy. In this multi-country study, we compared multiplex real-time PCR for enteric bacterial, parasitic and viral pathogens in stool samples from symptomatic patients and matched asymptomatic controls in Côte d’Ivoire, Mali and Nepal. Among 1826 stool samples, the prevalence of most pathogens was highest in Mali, being up to threefold higher than in Côte d’Ivoire and up to tenfold higher than in Nepal. In all settings, the most prevalent bacteria were EAEC (13.0–39.9%) and Campylobacter spp. (3.9–35.3%). Giardia intestinalis was the predominant intestinal protozoon (2.9–20.5%), and adenovirus 40/41 was the most frequently observed viral pathogen (6.3–25.1%). Significantly different prevalences between symptomatic and asymptomatic individuals were observed for Campylobacter, EIEC and ETEC in the two African sites, and for norovirus in Nepal. Multiple species pathogen infection was common in Côte d’Ivoire and Mali, but rarely found in Nepal. We observed that molecular testing detected multiple enteric pathogens and showed low discriminatory accuracy to distinguish between symptomatic and asymptomatic individuals. Yet, multiplex PCR allowed for direct comparison between different countries and revealed considerable setting-specificity.

Project-based learning (PBL) grounds instruction in authentic learning experiences where students engage in real-world explorations that culminate in a final product or performance. We report on a mixed methods study with 43 ninth-grade English language arts (ELA) teachers (22 PBL and 21 comparison) and 1,671 students exploring the feasibility of enacting PBL in ELA classrooms and examining how teachers and students perceived this approach to learning. PBL teachers enacted PBL design principles significantly more than comparison teachers. The majority of PBL teachers perceived positive instructional shifts including more student-centered and authentic learning, more student choice, and greater student engagement. Many teachers also expressed a sense of renewal and passion. Students in PBL classrooms reported more meaningful learning experiences, opportunities for collaboration, and other aspects of social and emotional learning. We discuss tensions, including the challenge of covering required content and skills within a PBL-focused classroom.

Background/purpose: British, European and American universities are increasingly adopting competency-based learning, yet, there are different and conflicting definitions of competence, competency, and competency-based learning. Consequently, multiple interpretations and understandings are held by educators in respect of what these terms mean, when applied to their own teaching and assessment practices. Therefore, unless informed and considered discussion has taken place amongst staff about their individual understandings and interpretations, any development of new, competency-based assessment processes and procedures, is necessarily problematic. The main purpose of the paper is to stimulate reflection and discussion, so that teaching staff can arrive at a common understanding and interpretation of what competency-based education is, so that they may develop appropriate, authentic and equitable assessment processes. Materials/methods: The methodology used was a systematic review of literature on competence, competency-based learning and the assessment of competency-based learning. Conclusion: This paper provides an overview of the main issues and tensions involved in clearly defining competency within higher education programmes and assessing competence, along with two clear recommendations for practice. The recommendations have significance for all higher education teaching staff involved in programmes of competency-based learning.

Abstract Background There is increasing epidemiological evidence supporting the association between onchocerciasis and seizures, reinforcing the concept of onchocerciasis-associated epilepsy (OAE). The aim of this paper is to provide an update on the new knowledge about OAE and to propose recommendations to the World Health Organization how to address this public health problem. Main text During the 2nd International Workshop on OAE held on 19–21 September, 2023, in Antwerp, Belgium, participants recognised OAE as a substantial yet neglected public health problem, particularly in areas of sub-Saharan Africa where onchocerciasis remains hyperendemic. Evidence from prospective population-based studies suggest that strengthening onchocerciasis elimination efforts leads to a significant reduction of OAE incidence. There is a need to validate an OAE case definition to estimate the burden of disease and identify onchocerciasis-endemic areas requiring intensification of onchocerciasis elimination programmes and integration of epilepsy care. It is expected that raising awareness about OAE will boost the population uptake of ivermectin. The implementation of a community-based epilepsy treatment programme offering free anti-seizure medications (ASMs) has shown high effectiveness in reducing the frequency of seizures and improving the overall quality of life of people with epilepsy. Conclusions To reduce OAE burden, enhanced collaboration between onchocerciasis and mental health programmes at community, national, and international levels is required. Urgent efforts are needed to ensure the uninterrupted provision of free ASMs in onchocerciasis-endemic areas. Furthermore, OAE should be included in the quantification of the onchocerciasis disease burden. Graphical Abstract

Personal tutoring is renowned for the positive role it can play in supporting student satisfaction, engagement and attainment outcomes in higher education. Surprisingly though, few studies have specifically investigated the demands of this role from the perspective of the personal tutor. Through the theoretical lens of Role Theory, this study explored university tutors' experiences of their personal tutoring role within a sport educational setting at a United Kingdom university. All data was collected through face-to-face semi structured qualitative interviews and analysed using thematic analysis. Key findings were the negative impact of personal tutoring on participants role multiplicity, intra-role accumulation and role identity. Most participants viewed the role as being time consuming, emotionally challenging and one they would prefer not to undertake (role multiplicity), feeling under qualified and ill-equipped in assisting their tutees because of the increasingly serious and complex nature of non-academic related issues presented (intra-role accumulation). Several lacked confidence and interest in the role, finding it to be stressful and instead favouring greater research responsibilities within their workloads (role identity). The collective findings provide academic colleagues and senior university management teams with evidence to inform future institutional policies and practices. This will help ensure personal tutors working across multiple disciplines and academic levels fully understand what the role is, the demands they are likely to encounter, the continued professional development required to facilitate and support the role and how the role should be better recognised in academic promotion criteria. Study limitations and future research avenues are discussed.

Background: Natureculture (Fuentes, 2010; Haraway, 2003) constructs offer a powerful framework for science education to explore learners' interactions with and understanding of the natural world. Technologies such as Augmented Reality (AR) designed to reveal pets' sensory worlds and companionship with pets can facilitate learners' harmonious relationships with significant others in naturecultures. Methods: At a two-week virtual summer camp, we engaged teens in inquiring into dogs' and cats' senses using selective color filters, investigations, experience design projects, and understanding how the umwelt (von Uexküll, 2001) of pets impacts their lives with humans. We qualitatively analyzed participants' talk, extensive notes, and projects completed at the workshop. Findings: We found that teens engaged in the science and engineering practices of planning and carrying out investigations, constructing explanations and designing solutions, and questioning while investigating specific aspects of their pets' lives. Further, we found that teens checking and taking pets' perspectives while caring for them shaped their productive engagement in these practices. The relationship between pets and humans facilitated an ecological and relational approach to science learning. Contribution: Our findings suggest that relational practices of caring and perspective-taking coexist with scientific practices and enrich scientific inquiry.

Background: Sub-Saharan Africa stands out as one of the regions most affected by the climate crisis, while it has contributed to the problem only marginally. The foreseen negative effect on health adds great stress to the already overburdened health systems. Health systems' adaptation to climate change is, therefore, urgently needed to better protect human health. There is, however, scant evidence on how adaption is being planned and implemented in Africa. The aim of this study was to review the literature on health system adaptation in sub-Saharan Africa. Methods: In this scoping review and case study, we first carried out the scoping review, searching for publications on adaptation measures using the PubMed, Science Direct, and Web of Science databases on July 1, 2023. We included papers in English and French that addressed the adaptation of health systems in countries in sub-Saharan Africa without time limit. Second, we did a case study of the design and implementation of the National Adaptation Plan of Benin, with a specific focus on the policy-making process underlying the plan, whereby we used the health policy triangle as a policy analysis framework. Data were collected through a document review of national policy plans, reports, and evaluations. Findings: A total of 14 papers met the inclusion criteria, showing that climate change adaptation remains a niche in the literature for sub-Saharan Africa. Most included papers were authored by individuals from high-income countries. Health system adaptation measures cover seven domains: health systems strengthening; policy and planning; financing and implementation; information and capacity building; societal resilience; disaster risk prevention, preparedness, response, and recovery; and mitigation. The review found that the dominant role of global agencies in supporting or steering health system adaptation planning contributes to policy mimicry across countries, as confirmed by the case study of the adaptation plan in Benin. Benin's National Adaptation Plan prioritised three climate hazards: heat, drought, and flooding. Although the financial and technical inputs of international agencies effectively support Benin's adaptation planning, these inputs might induce a more narrow focus that does not fully respond to Benin's needs in terms of climate shocks and adaptation priorities. Interpretation: Health systems in sub-Saharan Africa are already adapting to climate change. Future research could focus on how national governments could develop adaptation plans that are responsive to local needs by making the needs analysis and priority-setting processes more inclusive of local stakeholders.

An increasing number of real estate actors appear to be searching for ways to incorporate nature and biodiversity in urban development projects. In this article, we study three Dutch urban development projects with high biodiversity ambitions in order to learn how they came to fruition. We combine transition theory with practice theory and identify key barriers and drivers on the basis of these approaches. We highlight that incorporating biodiversity in urban development projects requires considerable knowledge development, implies a higher entrepreneurial risk and asks for various pragmatic solutions to overcome barriers. We identify four key recommendations for promoting nature-inclusive urban development: (1) facilitate knowledge development and exchange; (2) incorporate and reward biodiversity in environmental certification schemes and tender criteria; (3) translate a strategic vision on biodiversity into concrete regulations to bridge the policy implementation gap; (4) stimulate the uptake of nature-inclusive urban development in corporate visions.

BackgroundFasciolosis is an emerging public health threat in a number of regions worldwide. To date, we lack an overview of both its occurrence and distribution in Southeast Asia across all actors involved in the life cycle, which impedes the development of disease control measures. Therefore, our objective was to collect recent information on the distribution and the prevalence of Fasciola spp. and the associated risk factors for infection in humans, animals, snails and plant carriers in Southeast Asia.MethodologyBibliographic and grey literature databases as well as reference lists of important review articles were searched for relevant records published between January 1st, 2000, and June 30th, 2022. The systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for reporting systematic reviews. A total of 3,887 records were retrieved, of which 100 were included in the final analysis.Principal findingsThe studies focused mainly on one host species (96.0%), with Fasciola spp. infection in animals being the most studied (72.0%), followed by humans (21.0%). Based on the used inclusion and exclusion criteria, reports were retrieved describing the presence of Fasciola spp. infection in seven out of 11 countries in Southeast Asia. Depending on the diagnostic tool applied, the prevalence of Fasciola spp. infection ranged between 0.3% and 66.7% in humans, between 0% and 97.8% in animals, and between 0% and 66.2% in snails. There were no studies reporting the presence of metacercariae on plant carriers.Conclusions/significanceOur study reconfirms that Fasciola spp. infections are widespread and highly prevalent in Southeast Asia, but it remains difficult to accurately assess the true occurrence of Fasciola spp. in absence of well-designed surveys covering all hosts. As next steps we propose to assess the occurrence of the infection across all actors involved in the transmission, to identify associated risk factors and to estimate the burden of the disease to support national and international decision makers.
