What is the effect of personal discrimination on the political engagement of ethnic and racial minorities? Existing research theorizes increased engagement, but evidence is mixed. The discrimination and political engagement link is tested across six countries: Canada, Denmark, France, Germany, the United Kingdom, and the United States. Interest in politics and political actions (e.g. protest and donations) show constant relationships: people who have experienced discrimination have more interest in politics and take more political actions. There is no clear evidence of different effects of political vs social discrimination. However, the link between turnout and discrimination varies systematically across countries: a positive correlation in three separate American datasets, but mixed and null in other countries. This may be the result of the distinctive American conflict over voting rights for racial minorities. The conclusion discusses priorities for future research, including a focus on establishing causal relationships and testing mechanisms.
This research identified the key determinants and designed a novel Bayesian three-dimension convolution neural network (3D-CNN) for COVID-19 mass casualty incidents (MCI) triage recommendation.
Methods
109 articles between 2019 and 2022 were archived from MEDLINE databases. An empirical review and content analysis were done to find out the triage determinants and a Bayesian 3-D CNN model was designed for triage recommendation.
Results
35 out of 109 articles were used. The severity of infection (signs and symptoms of coronavirus), likelihood of spreading (attitudes of pandemic spreading, personal behaviors, and government policy), and available resources (physician and medication availability, hospital vacancy, and evacuation assets) were the identified determinants. The likelihoods of having COVID-19 were calculated with a Bayesian network based on the parameters of the three determinants, and were pre-processed for training the 3D-CNN model with the COVID19 test result, recover history, and medication outcome for “immediate (hospital admission with immediate medical care)”, “delayed (quarantine center and observation)”, “minimal (home quarantine with medication)”, “semi-minimal (home quarantine without medication)”, or “no priority (no therapeutic resources)” triage recommendation.
Conclusions
The determinants and AI model classify patients to an optimal healthcare facility for reducing disaster medicine risk. The model verification and validation were undergoing.
We perform simulations of an impulsively started, axisymmetric viscoelastic jet exiting a nozzle and entering a stagnant gas phase using the open-source code Basilisk. This code allows for efficient computations through an adaptively refined volume-of-fluid technique that can accurately capture the deformation of the liquid–gas interface. We use the FENE-P constitutive equation to describe the viscoelasticity of the liquid, and employ the log-conformation transformation, which provides stable solutions for the evolution of the conformation tensor as the jet thins down under the action of interfacial tension. For the first time, the entire jetting and breakup process of a viscoelastic fluid is simulated, including the pre-shearing flow through the nozzle, which results in an inhomogeneous initial radial stress distribution in the fluid thread that affects the subsequent breakup dynamics. The evolution of the velocity field and the elastic stresses in the nozzle are validated against analytical solutions where possible, and the early-stage dynamics of the jet evolution are compared favourably to the predictions of linear stability theory. We study the effect of the flow inside the nozzle on the thinning dynamics of the viscoelastic jet (which develops distinctive ‘beads-on-a-string’ structures) and on the spatio-temporal evolution of the polymeric stresses in order to systematically explore the dependence of the filament thinning and breakup characteristics on the initial axial momentum of the jet and the extensibility of the dissolved polymer chains.
To elucidate the association between financial challenges, healthcare needs, and their subsequent impact on individuals’ mental health, physical well-being, and quality of life.
Methods
ChiKobi Health conducted a market research survey consisting of twenty questions. 25 participants responded, providing insights into their emotional states due to health or financial situations, daily energy levels, mental health associations with financial and healthcare situations, overall quality of life, experiences with chronic pain, physical functioning, and interests in healthcare management services and holistic products.
Results
Key findings indicate: 88% of respondents occasionally to often felt emotionally drained due to health or financial situations. 80% rated their overall quality of life as good to excellent, but 40% have experienced chronic pain that interfered with daily activities. 48% felt their physical health was occasionally to always hindered by financial or healthcare limitations. 60% expressed interest in personalized healthcare manager services and 84% in holistic medical products for preventative health needs.
Conclusions
Financial strain and healthcare challenges are significantly intertwined with individuals’ emotional and physical well-being. Given the current global challenges and climate change effects leading to more health-related crises, understanding these interrelationships is paramount for disaster medicine and public health efforts, particularly for vulnerable populations.
Reducing inequalities in preconception health and care is critical to improving the health and life chances of current and future generations. A hybrid workshop was held at the 2023 UK Preconception Early and Mid-Career Researchers (EMCR) Network conference to co-develop recommendations on ways to address inequalities in preconception health and care. The workshop engaged multi-disciplinary professionals across diverse career stages and people with lived experience (total n = 69). Interactive discussions explored barriers to achieving optimal preconception health, driving influences of inequalities and recommendations. The Socio-Ecological Model framed the identified themes, with recommendations structured at interpersonal (e.g. community engagement), institutional (e.g. integration of preconception care within existing services) and environmental/societal levels (e.g. education in schools). The co-developed recommendations provide a framework for addressing inequalities in preconception health, emphasising the importance of a whole-systems approach. Further research and evidence-based interventions are now needed to advance the advocacy and implementation of our recommendations.
Little is known about the distribution and natural history of hoverflies (Diptera: Syrphidae) in western Canada. Filling in knowledge gaps and tracking this potentially changing fauna are important because hoverflies are likely important pollinators and are natural pest control agents for crops. Hoverflies were collected using Malaise traps placed near fields seeded to canola in central Alberta from May to August 2021. Platycheirus varipes Curran represents a new species record for Alberta. Two species of conservation concern and two species with extremely limited collection records were also collected. A species that was previously found only in mountainous regions and another three species whose Albertan records consisted only of iNaturalist records were found.
Each year, disasters impact over 50 million, and conflicts are indirectly related to 1,000,000 deaths. Traditionally, humanitarians help in two ways: Deployment: sending healthcare workers to provide direct care, and Development: training local healthcare workers. But these routes limit who can be reached and how quickly. We envision a scalable solution that moves beyond traditional humanitarian avenues to empower the public to save lives and reduce suffering through equitable, open-access education.

Kokum [Garcinia indica (Thouars) Choisy] is a multi-purpose tree with culinary, cosmetics and pharmaceutical uses found popular in Konkan region of India. ICAR-NBPGR Regional Station, Thrissur made a systematic exploration and collection missions on kokum over a period from 1987–2004 and collected 31 accessions from various parts of Konkan region to characterize them using morphological characters and also to investigate their flowering and fruiting behaviour. Totally, 85 trees planted in Field Gene Bank in which only 67 trees (23 accessions) survived during field establishment. Among them, 32 (47.8%) were male and remaining 25 identified as female (37.3%) and 10 as co-sexual (14.9%). Fruit bearing ability noticed only in both female and co-sexual trees with huge variation in fruits. Morphological characterization of 33 trees with fruiting (23 accessions) for 35 morphological traits revealed presence of considerable amount of variation among them on basis of CV%. Highest positive correlation observed between fresh seed weight and fresh kernel weight (0.92). Cluster analysis formed four major clusters with Cluster I and II comprising male/bisexual genotypes and Cluster III and IV with female genotypes and it clearly distinguished male/bisexual genotypes from female ones. PCA analysis accounted 65.6% of genetic variation present among accessions by first three most informative PCs. Superior accessions identified for important traits will be more useful in industrial aspects of preparing kokum butter and juice. Further, seasonal difference identified in fruiting and maturity of fruits well-before onset of monsoon may be exploited by kokum industries for drying and processing of fruits.
In the field of cancer, many cancer patient associations (CPAs) have been established in Türkiye to support individuals living with cancer (ILCs) throughout the diagnosis and treatment processes. The presence of CPAs for ILCs became more significant after the major earthquakes in southeastern Türkiye in February 2023. The aim of this study is to identify the challenges of ILCs after the earthquakes from the perspective of CPA members.
Methods
This study employed a qualitative approach. The data collection method was in-depth interviews. Semi-structured, open-ended interviews were conducted with 15 volunteers who work with ILCs, selected through purposeful sampling. The data were analyzed by using inductive thematic analysis. This study was conducted between April and May 2023.
Results
Three main themes (problems of ILCs caused by earthquakes, access to health care, future concerns) and 11 subthemes were extracted through analyzing interviews.
Conclusion
ILCs experienced diverse difficulties after earthquakes. Members of CPAs observed that acute interventions to injured people and humanitarian aid activities had the first-place importance after the earthquake, while cancer-related care took the second place, anticipating devastating outcomes for the future of their care. CPAs should be supported by the public, local governments, and central government in their endeavors for ILCs.
Melt-front instabilities during the combustion of a spinning polymethylmethacrylate disk in air are investigated. Mainly straight rivulet-type flow patterns were found, though under certain conditions saw-tooth patterns were observed. The measured wavelengths of the instabilities agree with earlier theoretical predictions of driven contact-line instabilities.
The article introduces and studies Hausdorff–Berezin operators on the unit ball in a complex space. These operators are a natural generalization of the Berezin transform. In addition, the class of such operators contains, for example, the invariant Green potential, and some other operators of complex analysis. Sufficient and necessary conditions for boundedness in the space of p – integrable functions with Haar measure (invariant with respect to involutive automorphisms of the unit ball) are given. We also provide results on compactness of Hausdorff–Berezin operators in Lebesgue spaces on the unit ball. Such operators have previously been introduced and studied in the context of the unit disc in the complex plane. Present work is a natural continuation of these studies.
Liquid bridges are formed when a flowing liquid interacts with multiple parallel fibres, as relevant to heat and mass transfer applications that utilize flow down fibre arrays. We perform a comprehensive experimental study of flowing liquid bridges between two vertical fibres whose spacing is controlled dynamically in our experimental apparatus. The bridge patterns exhibit a regular periodic spacing typical of absolute instability for low flow rates, but become spatially inhomogeneous above a critical flow rate where the base flow is convectively unstable. The shapes of individual bridges and their associated dynamics are measured, as they depend upon the liquid properties, and fibre geometry/spacing. The bridge length scales similarly to static bridges between parallel fibres. The bridge dynamics exhibits a dependence on viscosity and scale with the impedance. A simple energy balance is used to derive a scaling relationship for the bridge velocity that captures the general trend of our experimental data. Finally, we demonstrate that these scalings similarly apply when the fibres are dynamically separated or brought together.
Particles in pressure-driven channel flow are often inhomogeneously distributed. Two modes of low-Reynolds-number instability, absent in Poiseuille flow of clean fluid, are created by inhomogeneous particle loading, and their mechanism is worked out here. Two distinct classes of behaviour are seen: when the critical layer of the dominant perturbation overlaps with variations in particle concentration, the new instabilities arise, which we term overlap modes. But when the layers are distinct, only the traditional Tollmien–Schlichting mode of instability occurs. We derive the dominant critical-layer balance equations in this flow along the lines done classically for clean fluid. These reveal how concentration variations within the critical layer cause the two particle-driven instabilities. As a result of these variations, disturbance kinetic energy production is qualitatively and majorly altered. Surprisingly, the two overlap modes, although completely different in the symmetry of the eigenstructure and regime of exponential growth, show practically identical energy budgets, highlighting the relevance of variations within the critical layer. The wall layer is shown to be unimportant. We derive a minimal composite theory comprising all terms in the complete equation which are dominant somewhere in the flow, and show that it contains the essential physics. When particles are infinitely dense relative to the fluid, the volume fraction is negligible. But for finite density ratios, the volume fraction of particles causes a profile of effective viscosity. This is shown to be uniformly stabilizing in the present flow. Gravity is neglected here, and will be important to study in the future. So will the transient growth of perturbations due to non-normality of the stability operator, in a quest for the mechanism of transition to turbulence.
Kawasaki disease is an acute febrile disease causing systemic vasculitis that is common in infants and young children. This study was conducted to explore the relationships of the rs1412125, and rs2249825 single nucleotide polymorphisms of the high mobility group box 1 gene to Kawasaki disease and its complication of coronary artery injury.
Methods:
In total, 200 children with Kawasaki disease (49 with coronary artery injury) and 200 healthy controls were enrolled in this study. Polymerase chain reaction was used to amplify the target gene, and direct sequencing was performed to determine distributions at the rs1412125 T/C and rs2249825 C/G loci in the HMGB1 gene. The chi-squared test was used to compare data between groups. Linkage disequilibrium coefficients and single nucleotide polymorphism haplotype analysis were conducted, and a false-positive report probability analysis was used to assess significant associations. Expression quantitative trait loci analysis was performed to determine if single nucleotide polymorphisms affected mRNA levels via the GTEx portal.
Results:
Significant differences in the genotype TT, TC, and CC distributions (χ2 = 7.918, P = 0.019) and allele T and C frequencies (χ2 = 6.125, P = 0.013) of rs1412125 T/C locus were found between the Kawasaki disease and healthy control groups. The genotype CC was associated with a greater Kawasaki disease risk [odds ratio = 3.205, 95% confidence interval = 1.352–7.595, χ2 = 7.560, P = 0.006]. C allele carriers had a higher Kawasaki disease risk than did T allele carriers (odds ratio = 1.469, 95% confidence interval = 1.083–1.993, χ2 = 6.125, P = 0.013). The rs1412125 genotype T/C distribution (χ2 = 10.906, P = 0.004) and allele frequencies (χ2 = 8.813, P = 0.003) differed significantly between patients with and without coronary artery injury. In the dominant model, the coronary artery injury risk was 3.006 times greater for patients with the TT genotype than for those with the other genotypes (odds ratio = 3.006, 95% confidence interval = 1.540–5.867, χ2 = 10.875, P = 0.001). No significant difference in the rs2249825 genotype C/G distribution or allele frequencies was found between the Kawasaki disease and control groups, or between the coronary artery injury and without coronary artery injury groups.
Conclusions:
The rs1412125 polymorphism of the HMGB1 gene is associated with Kawasaki disease and its coronary artery injury complication. The CC genotype may be a risk factor for Kawasaki disease onset, and the TT genotype may be a risk factor for coronary artery injury in Kawasaki disease.
Cardiac intensive care providers require a comprehensive understanding of cardiac output and oxygen delivery. The estimation of cardiac output in clinical practice often relies on thermodilution and the Fick principle. Central venous saturation and lactate levels are commonly used indicators for cardiac output assessment. However, the relationship between venous lactate levels and venous oxygen saturation in paediatric cardiac intensive care patients remains unclear.
Methods:
This is a single-centre retrospective pilot study aimed to investigate the correlation between venous lactate and venous oxygen saturation in paediatric patients. Data collected included venous saturation, heart rate, mean arterial blood pressure, arterial saturation by pulse oximetry, cerebral and renal near-infra-red spectroscopy values, and the presence of a functionally univentricular heart. Statistical analyses included Bayesian Pearson correlation and regression analyses.
Results:
A total of 203 data points from 37 unique patients were included in the analysis. There was no significant correlation between serum lactate and venous saturation (correlation coefficient = –0.01; Bayes factor 10 = 0.06). Serum lactate also did not correlate with other haemodynamic metrics. Venous saturation showed correlations with arterial saturation and cerebral and renal near-infra-red spectroscopy. Regression analysis revealed that parallel circulation, arterial saturation, and cerebral near-infra-red spectroscopy were predictive of venous saturation. The following equation resulted from the regression analysis: 68.0 – (12.7 x parallel circulation) – (0.8 x arterial saturation) + (0.3 x cerebral near-infra-red spectroscopy). This model had a Bayes factor 10 of 0.03 and adjusted R-squared was 0.29.
Conclusion:
In paediatric cardiac intensive care patients, there is no significant correlation between venous lactate and venous saturation, suggesting that lactate may not be a reliable marker for assessing the adequacy of oxygen delivery in this population. Only a weak correlation could be identified once the venous saturation was 70% or lower. Additional research is needed to explore alternative markers for monitoring oxygen delivery in critically ill paediatric patients.
Equations are given which allow an analyst to obtain a correct absolute quantitative phase analysis via the internal standard method when a reference material with a known crystallinity of less than 100% is used. Comparisons are made with previous equations, and a numerical example is given.
The increased global prevalence of type II diabetes mellitus (T2DM) is associated with consumption of low fibre ‘Western diets’. Characteristic metabolic parameters of these individuals include insulin resistance, high fasting and postprandial glucose, as well as low-grade systemic inflammation. Gut microbiota composition is altered significantly in these cohorts suggesting a causative link between diet, microbiota and disease. Dietary fibre consumption has been shown to alleviate these changes and improve glucose parameters in individuals with metabolic disease. We previously reported that yeast β-glucan (yeast beta-1,3/1,6-D-glucan; Wellmune) supplementation ameliorated hyperinsulinaemia and insulin resistance in a murine model. Here, we conducted a randomised, placebo-controlled, two-armed dietary fibre phase I exploratory intervention study in patients with T2DM. The primary outcome measure was alteration to microbiota composition, while the secondary outcome measures included markers of glycaemic control, inflammation as well as metabolomics. Patients were supplemented with 2·5g/day of maltodextrin (placebo) or yeast β-1,3/1,6-D-glucan (treatment). Yeast β-glucan (Wellmune) lowered insulin resistance compared with the placebo maltodextrin after 8 weeks of consumption. TNFα was significantly lower after 4 weeks of β-glucan supplementation. Significantly higher fecal concentrations of several bile acids were detected in the treatment group when compared with the placebo after 8 weeks. These included tauroursodeoxycholic acid, which was previously shown to improve glucose control and lower insulin resistance. Interestingly, the hypoglycaemic and anti-inflammatory effect of yeast β-glucan was independent of any changes in fecal microbiota composition or short-chain fatty acid levels. Our findings highlight the potential of yeast β-glucan to lower insulin resistance in patients with T2DM.
