    From Springer Nature via Jisc Publications RouterAlastair Ager - ORCID 0000-0002-9474-3563 https://orcid.org/0000-0002-9474-3563Background: Evidence of ‘what works’ in humanitarian programming is important for addressing the disruptive consequences of conflict and forced displacement. However, collecting robust scientific evidence, and ensuring contextual relevance, is challenging. We measured the biological, psychosocial, and cognitive impacts of a structured psychosocial intervention, implemented by Mercy Corps with Syrian refugees and Jordanian host-community youth. In this paper, we present a case analysis of this evaluation study and reflect on the scientific contributions of the work, the challenges experienced in its delivery, and the strategies deployed to address them.Discussion: We identified challenges with respect to study design, methods, and dissemination: these included the logistics and acceptability of implementing a randomized controlled trial in a humanitarian context, the selection and refinement of culturally-relevant research tools and community-based practices, and the dissemination of results to multiple stakeholders. We demonstrated beneficial and sustained impacts on self-reports of insecurity, stress, and mental health; developed a reliable and culturally-relevant measure of resilience; experimentally tested cognitive skills; and showed that levels of cortisol, a biomarker of chronic stress, reduced by one third in response to intervention. Using stress biomarkers offered proof-of-concept evidence, beyond self-reported data: interventions targeting mental health and psychosocial wellbeing can regulate physiological stress in the body as well as improve self-reported mental health and wellbeing. We built constructive dialogue between local communities, scholars, humanitarian practitioners, and policy-makers.Conclusions: Our work shows the value of rigorous research in humanitarian settings, emphasizing relevance for local communities and meaningful ways to build research ownership. Findings encourage the adoption of cognitive measures and stress biomarkers alongside self-report surveys in evaluating programme impacts. High-quality scientific research with youth can be feasible, useful, and ethical in humanitarian settings.pubpu

    PURPOSE: Paracetamol has been associated with a reduction in blood pressure, especially in febrile, critically-ill adults. We hypothesised that blood pressure would fall following administration of paracetamol in critically-ill children and this effect would be greater during fever and among children with a high body surface area to weight ratio. METHODS: A 12-month prospective observational study of children (0-16years) admitted to paediatric intensive care, who underwent pulse contour analysis and received paracetamol concurrently. RESULTS: Mean arterial blood pressure decreased significantly by 4.7% from baseline (95% CI 1.75-8.07%) in 31 children following 148 doses of paracetamol. The nadir was 2-hour post-dose. The effect was pronounced in children with fever at baseline (6.4%, 95% CI 2.8-10%), although this was not statistically significant. There was no simple relationship between this effect and body surface area to weight ratio. The association between a change in blood pressure and changes in heart rate or measured stroke volume was poor; therefore it was likely that a change in the systemic vascular resistance contributes most to this effect. CONCLUSION: There is a significant but modest reduction in blood pressure post-paracetamol in critically-ill children. This is likely related to a change in systemic vascular resistance

    Predicting school uptake of The Daily Mile in Northern Ireland- a data linkage study with School Census Data and Multiple Deprivation Measures

    BACKGROUND: Participating in physical activity benefits health, yet a majority of children remain inactive. The Daily Mile™ (TDM) originated in Scotland in 2012 with the aim of increasing primary school children's physical fitness. Despite being a practically feasible and popular initiative, it remains unclear the extent to which schools implement TDM, and whether TDM core principles are adhered to (i.e., run or jog at least 3-days per week). In Northern Ireland it is unknown how many schools regularly participate in TDM, and whether there is an association between TDM participation with school type, school location, size, total number of children attending the school, school deprivation level, and/or motivation as measured by the COM-B model (Capabilities, Opportunities, Motivation model of behaviour). Therefore, this study aimed to quantify the uptake of TDM in Northern Ireland, assess whether schools are following the core principles, and analyse if there is an association between aforesaid demographic factors and TDM participation.METHODS: An online cross-sectional survey was sent to all primary and special education schools in Northern Ireland with the support of the Education Authority for Northern Ireland and the Public Health Agency for Northern Ireland. The survey was completed by the school principal or teacher, and was available from 31st August until 16th December 2022. Survey results were linked with the 2021/2022 Northern Ireland School Census Data and Northern Ireland Multiple Deprivation Measure 2017. Quantitative and qualitative questions were included in the survey to assess participation and implementation of TDM.RESULTS: The survey received 609 school responses. After data cleaning, and removal of duplicates from schools a sample of 358 primary schools (45%) and 19 special education schools (47.5%) was analysed. Over half (54.7%) of primary schools and 36.8% of special education schools reported taking part in TDM. More special education needs schools reported taking part in their own version of an 'active mile' rather than TDM formally, and qualitative findings showed TDM was not perceived as appropriate for many children in special educational settings. There was wide variation in adherence to TDM core principles. A multivariate binary logistic regression model was fitted to the data, but it was not statistically significant (χ2(17) = 22.689, p = .160). However, univariate effects showed that increasing levels on COM-B (Capability) was associated with increased likelihood of TDM participation (OR = 2.506), and Catholic Maintained schools were almost twice as likely as Controlled schools to be delivering TDM (OR = 1.919). There was no association found between deprivation and TDM uptake.CONCLUSION: Encouragingly over 50% of schools in Northern Ireland reported taking part in TDM. However, despite being a low-cost and practically feasible physical activity initiative, further intervention work with sound research methodology is needed to promote adherence to TDM core principles to maximise benefits to children's health. Furthermore, concerted efforts are required to adjust TDM so that it is inclusive for all educational settings, and children's abilities.</p

    Living donor kidney transplant is the ideal treatment option for end-stage renal disease; however, the decision to pursue living donor kidney transplant is complex and challenging. Measurement invariance of living donor kidney transplant Decisional Balance and Self-Efficacy across gender (male/female), race (Black/White), and education level (no college/college or higher) were examined using a sequential approach. Full strict invariance was found for Decisional Balance and Self-Efficacy for gender and partial strict invariance was found for Decisional Balance and Self-Efficacy across race and education level. This information will inform tailored feedback based on these constructs in future intervention studies targeting behavior change among specific demographic subgroups

    Metabolomic and Functional Genomic Analyses Reveal Varietal Differences in Bioactive Compounds of Cooked Rice

    Emerging evidence supports that cooked rice (Oryza sativa L.) contains metabolites with biomedical activities, yet little is known about the genetic diversity that is responsible for metabolite variation and differences in health traits. Metabolites from ten diverse varieties of cooked rice were detected using ultra performance liquid chromatography coupled to mass spectrometry. A total of 3,097 compounds were detected, of which 25% differed among the ten varieties. Multivariate analyses of the metabolite profiles showed that the chemical diversity among the varieties cluster according to their defined subspecies classifications: indica, japonica, and aus. Metabolite-specific genetic diversity in rice was investigated by analyzing a collection of single nucleotide polymorphisms (SNPs) in genes from biochemical pathways of nutritional importance. Two classes of bioactive compounds, phenolics and vitamin E, contained nonsynonymous SNPs and SNPs in the 5′ and 3′ untranslated regions for genes in their biosynthesis pathways. Total phenolics and tocopherol concentrations were determined to examine the effect of the genetic diversity among the ten varieties. Per gram of cooked rice, total phenolics ranged from 113.7 to 392.6 µg (gallic acid equivalents), and total tocopherols ranged between 7.2 and 20.9 µg. The variation in the cooked rice metabolome and quantities of bioactive components supports that the SNP-based genetic diversity influenced nutritional components in rice, and that this approach may guide rice improvement strategies for plant and human health

    Urban agglomerations expose citizens to ever-increasing risks from heat, air pollution, noise stress, and reduced nature connectedness. Concurrently, accumulating evidence suggests various health benefits by exposure to urban natural spaces (World Health Organization, 2016a; Bratman et al., 2019). Existing research suggests an array of benefits of contact with nature which are linked to physical activity (e.g., green exercise), active travel, and residential proximity to greenspace. Psychological benefits appear to be related to mood, well-being, attention and pro-environmental behavior; physiological benefits have been described in terms of increased physical activity, improved cardiovascular parameters, reduced stress hormones, and enhanced immune resources (Bowler et al., 2010; Li, 2010; Park et al., 2010; Calogiuri and Chroni, 2014; Hartig et al., 2014; van den Bosch and Sang, 2017)

    Dry Bean: A Protein-Rich Superfood With Carbohydrate Characteristics That Can Close the Dietary Fiber Gap

    Get PDF
    Consumer food choices are often focused on protein intake, but the chosen sources are frequently either animal-based protein that has high fat content or plant-based protein that is low in other nutrients. In either case, these protein sources often lack dietary fiber, which is a nutrient of concern in the 2020–2025 Dietary Guide for Americans. Pulse crops, such as dry edible beans (Phaseolus vulgaris L.), are a rich source of dietary protein and contain approximately equal amounts of dietary fiber per 100 kcal edible portion; yet the consumer's attention has not been directed to this important fact. If product labeling were used to draw attention to the similar ratio of dietary protein to dietary fiber in dry bean and other pulses, measures of carbohydrate quality could also be highlighted. Dietary fiber is categorized into three fractions, namely, soluble (SDF), insoluble (IDF), and oligosaccharides (OLIGO), yet nutrient composition databases, as well as food labels, usually report only crude fiber. The objectives of this research were to measure the content of SDF, IDF, and OLIGO in a large genetically diverse panel of bean cultivars and improved germplasm (n = 275) and determine the impact of growing environment on the content of DF. Dietary fiber was evaluated using the American Association of Analytical Chemist 2011.25 method on bean seed grown at two locations. Dry bean cultivars differed for all DF components (P ≤ 0.05). Insoluble dietary fiber constituted the highest portion of total DF (54.0%), followed by SDF (29.1%) and OLIGO (16.8%). Mean total DF and all components did not differ among genotypes grown in two field environments. These results indicate that value could be added to dry bean by cultivar-specific food labeling for protein and components of dietary fiber

    Pinto bean (Phaseolus vulgaris L.) cultivars ‘Blackfoot’ (Reg. No. CV-316, PI 680632), ‘Nez Perce’ (Reg. No. CV-317, PI 680633), and ‘Twin Falls’ (Reg. No. CV-318, PI 680634) were developed at the University of Idaho, Kimberly Research and Extension Center in collaboration with researchers in Colorado, Nebraska, and Washington. Blackfoot and Nez Perce are sister cultivars derived from the same bulk population, UIP35 (USPT-CBB-1/3/‘Othello’/‘UI 906’//‘Topaz’/‘Buster’). Twin Falls was selected from the bulk population UIP40 (USPT-CBB-1/3/CO12650/USPT-ANT-1//Othello/ABL15). The F8 of both population bulks and checks were yield tested in the Western Regional Bean Trial in 2014 and 2015 and in the Cooperative Dry Bean Nursery in 2015. The three cultivars were yield tested in Idaho in 2015. They were also yield tested across nine production environments in Colorado, Idaho, Nebraska, and Washington in 2016. Blackfoot, Nez Perce, and Twin Falls are the first indeterminate erect Type II growth habit pinto bean cultivars resistant to Bean common mosaic virus (an aphid-vectored potyvirus) and bean rust developed at University of Idaho. Blackfoot has a compact Type IIA growth habit and produces little or no vine (i.e., elongated terminal axis with intertwined internodes that help the plant climb when provided support). In contrast, Nez Perce is tall and produces medium to long vines, with a Type IIB growth habit. Blackfoot has a mean maturity of 85 d and Nez Perce 95 d in southern Idaho. Twin Falls is a full-season cultivar (≥100 d) and relatively tall, with very small or no vines for climbing. The three cultivars have relatively smaller seed (100−1 seeds) than early-maturity pinto ‘Othello’ (≥35 g 100−1 seeds) in the Pacific Northwest

    Improving the Health Benefits of Snap Bean: Genome-Wide Association Studies of Total Phenolic Content

    Get PDF
    Snap beans are a significant source of micronutrients in the human diet. Among the micronutrients present in snap beans are phenolic compounds with known beneficial effects on human health, potentially via their metabolism by the gut-associated microbiome. The genetic pathways leading to the production of phenolics in snap bean pods remain uncertain. In this study, we quantified the level of total phenolic content (TPC) in the Bean Coordinated Agriculture Program (CAP) snap bean diversity panel of 149 accessions. The panel was characterized spectrophotometrically for phenolic content with a Folin-Ciocalteu colorimetric assay. Flower, seed and pod color were also quantified, as red, purple, yellow and brown colors are associated with anthocyanins and flavonols in common bean. Genotyping was performed through an Illumina Infinium Genechip BARCBEAN6K_3 single nucleotide polymorphism (SNP) array. Genome-Wide Association Studies (GWAS) analysis identified 11 quantitative trait nucleotides (QTN) associated with TPC. An SNP was identified for TPC on Pv07 located near the P gene, which is a major switch in the flavonoid biosynthetic pathway. Candidate genes were identified for seven of the 11 TPC QTN. Five regulatory genes were identified and represent novel sources of variation for exploitation in developing snap beans with higher phenolic levels for greater health benefits to the consumer
