Background: Education faced challenges during the COVID-19 pandemic. Although the United States has declared an end to the public health emergency, schools continue to be impacted. While considerable research has focused on the impact of the pandemic on students, fewer studies have focused on educators, and even less on educators who specialize in working with marginalized student populations. Methods: This study measured the impact of the pandemic impact on educators working with students from seasonal and migrant farmworker families to understand what supports educators need as schools plan for long-term recovery. A total of 1024 educators including early childhood education and K-12 teachers, as well as administrators, completed a COVID-19 questionnaire between October 2020 and January 2021, measuring their experiences as well as personal and work-related stressors during the pandemic. Results: Educators underwent difficult COVID-19 experiences and faced several factors contributing to personal and work-related stress. Personal stress factors included concerns about they themselves, or family members, becoming ill, concerns about the emotional/mental health of their family, and fear of loss/reduction in employment. Work-related stress factors included concerns about the emotional and mental health of co-workers. Conclusion: Educators working with migrant children need additional supports--including support from administrators, psychological services, and opportunities to give/receive colleague/peer support.

Recently, the California Department of Public Health issued an advisory related to the substantial rise in Coccidioidomycosis in California, which has been attributed in part to climate change and rapid housing development. Most cases are self-limiting, but some may spread to the meninges, resulting in coccidioidal meningitis (CM). Many providers mistakenly presume that CM is limited to patients who are immunocompromised. In this case series and literature review, we present 12 cases of CM in immunocompetent individuals seen at a single tertiary academic center between 1 January 2019 and 31 December 2023. All 12 cases developed complications, with 10 requiring ventriculoperitoneal shunting, 6 having spinal cord involvement (5 with cervical spine involvement), 4 having strokes, and 3 dying from complications related to CM. It is important to recognize CM as it may be life-threatening if not promptly diagnosed.

Centered on superiority over a certain group or individual, discrimination becomes predominant in prestigious institutions that pride themselves on exclusivity. Collegiate honors programs tend to deepen this practice by creating highly elite spaces accessible only to a select few. This rigidity can lead to an underrepresentation of historically marginalized groups, students who often lack the necessary resources for achieving academic excellence. This case study examines the ways honors programs inadvertently perpetuate discrimination among different social identities. Using inductive interviewing of honors students (n = 12) to gauge individual perceptions of program diversity, researchers rely on content analysis to generate four themes (relationship, discrimination, exclusion, conformity). By cross-analyzing participant responses with social identities, key programmatic components that may have led to covert systemic bias are uncovered. Results further indicate a possible link between a student's racial identity and their sense of belonging within the program, with people of color reporting more instances of "othering" and discrimination. This study reveals a pressing need for increasing access to honors for minority students and improving the level of integration and retention among students currently enrolled.

Gender studies have become relevant for English language teaching and initial teacher education. This study uses a narrative inquiry approach to inspect two language teachers' life stories in an initial teacher education program. We document how their femininities and identities are embodied through their language pedagogy since it is a praxis that allows resistance and resurgence against paradigms that limit their identities. Findings reveal that femininities provide a broader spectrum of individual gender realities and constructions. Teachers' femininities are embodied in teachers' practices. This is why some traits of these embodiments can be related to hegemonic aspects of gender, without this necessarily meaning that there is no resistance in the pedagogical field. On the contrary, it shows the capacity to redefine these attitudes that, from the pedagogical perspective, resist the hegemony of teacher gender identity.

Soil microbial communities impact carbon sequestration and release, biogeochemical cycling, and agricultural yields. These global effects rely on metabolic interactions that modulate community composition and function. However, the physicochemical and taxonomic complexity of soil and the scarcity of available isolates for phenotypic testing are significant barriers to studying soil microbial interactions. Corrinoids-the vitamin B12 family of cofactors-are critical for microbial metabolism, yet they are synthesized by only a subset of microbiome members. Here, we evaluated corrinoid production and dependence in soil bacteria as a model to investigate the ecological roles of microorganisms involved in metabolic interactions. We isolated and characterized a taxonomically diverse collection of 161 soil bacteria from a single study site. Most corrinoid-dependent bacteria in the collection prefer B12 over other corrinoids, while all tested producers synthesize B12, indicating metabolic compatibility between producers and dependents in the collection. Furthermore, a subset of producers release B12 at levels sufficient to support dependent isolates in laboratory culture at estimated ratios of up to 1000 dependents per producer. Within our isolate collection, we did not find strong phylogenetic patterns in corrinoid production or dependence. Upon investigating trends in the phylogenetic dispersion of corrinoid metabolism categories across sequenced bacteria from various environments, we found that these traits are conserved in 47 out of 85 genera. Together, these phenotypic and genomic results provide evidence for corrinoid-based metabolic interactions among bacteria and provide a framework for the study of nutrient-sharing ecological interactions in microbial communities.

Soil microbial communities perform critical ecosystem services through the collective metabolic activities of numerous individual organisms. Most microbes use corrinoids, a structurally diverse family of cofactors related to vitamin B12. Corrinoid structure influences the growth of individual microbes, yet how these growth responses scale to the community level remains unknown. Analysis of metagenome-assembled genomes suggests that corrinoids are supplied to the community by members of the archaeal and bacterial phyla Thermoproteota, Actinobacteria, and Proteobacteria. Corrinoids were found largely adhered to the soil matrix in a grassland soil, at levels exceeding those required by cultured bacteria. Enrichment cultures and soil microcosms seeded with different corrinoids showed distinct shifts in bacterial community composition, supporting the hypothesis that corrinoid structure can shape communities. Environmental context influenced both community- and taxon-specific responses to specific corrinoids. These results implicate corrinoids as key determinants of soil microbiome structure and suggest that environmental micronutrient reservoirs promote community stability.

Craniofacial phenotyping is critical for both syndrome delineation and diagnosis because craniofacial abnormalities occur in 30% of characterized genetic syndromes. Clinical reports, textbooks, and available software tools typically provide two-dimensional, static images and illustrations of the characteristic phenotypes of genetic syndromes. In this work, we provide an interactive web application that provides three-dimensional, dynamic visualizations for the characteristic craniofacial effects of 95 syndromes. Users can visualize syndrome facial appearance estimates quantified from data and easily compare craniofacial phenotypes of different syndromes. Our application also provides a map of morphological similarity between a target syndrome and other syndromes. Finally, users can upload 3D facial scans of individuals and compare them to our syndrome atlas estimates. In summary, we provide an interactive reference for the craniofacial phenotypes of syndromes that allows for precise, individual-specific comparisons of dysmorphology.

We describe a case of a young patient with a recurrent pleomorphic xanthoastrocytoma (PXA) showing unusual cell-in-cell (CiC) phenomena. We observed mostly viable but also necrotic neutrophils engulfed within tumor cells. The recurrent tumor was immunopositive for BRAFV600E mutant protein and showed CDKN2 homozygous deletions typical of PXA. Both genetic alterations were also reported in the original primary tumor. Unlike the original tumor that was GFAP and Olig-2 immunopositive, the recurrent neoplasm was largely negative for GFAP and Olig-2 suggesting dedifferentiation. The large malignant cells that contained the neutrophils were negative for histiocytic and lymphohematopoietic markers. Whereas CDKN2 homozygous deletion is common in PXA, its presence is rare in histiocytic neoplasms. Both reactive astrocytes and glial neoplasms very rarely may engulf neutrophils in a process resembling emperipolesis or cellular cannibalism. Future work may clarify which type of CiC pathway is involved.

ABSTRACT: Traits related to calving have a significant impact on animal welfare and farm profitability in dairy production systems. Identifying genomic regions associated with calving traits could contribute to refining dairy cattle breeding programs and management practices in the dairy industry. Therefore, the primary objectives of this study were to estimate genetic parameters and perform GWAS and functional enrichment analyses for stillbirth, gestation length, calf size, and calving ease traits in North American Jersey cattle. A total of 40,503 animals with phenotypic records and 5,398 animals genotyped for 45,101 SNPs were included in the analyses. Genetic parameters were estimated based on animal models and Bayesian methods. The effects of SNPs were estimated using the single-step GBLUP method. The heritability (SE) estimates ranged from 0.01 (0.01) for stillbirths in heifers to 0.11 (0.01) for gestation length in cows. The genetic correlations ranged from −0.58 (0.11) between calving ease and stillbirths in heifers to 0.44 (0.14) between calving ease and calf size in cows. Calving ease showed the highest genetic correlation between heifers and cows, 0.8 (0.22) respectively. The candidate genes identified, including MTHFR, SERPINA5, IGFBP3, and ZRANB1, are involved in key biological processes and metabolic pathways related to the studied traits. Reducing environmental variation and identifying novel indicators of reproduction traits in the Jersey breed are needed given the low heritability estimates for most traits evaluated in this study. In conclusion, this study provides a characterization of the genetic background of calving-related traits in Jersey cattle. The estimates obtained can be used to improve or build selection indexes in Jersey cattle breeding programs in North America.

This article is based on a literature review and analysis of studies related to social and armed conflicts in the Northern Cauca sub-region, where there is a diversity of ethnic communities such as indigenous peoples, especially the Nasa people, black communities and zones of peasant reserve. Methodologically, the review of publications made by legal anthropologists, sociologists and lawyers, and the researchers' own experience in the field, adding a critical analysis of the data collected, the conflictive panorama and transitional justice is shown from a historical-critical perspective. in a region rich in biodiversity and the possible transformations of the conflict.

Guidelines for testosterone replacement therapy (TRT) have been well studied and defined in adults, however, this remains less defined for adolescents and young men. There are a variety of conditions in adolescents and young men that necessitate TRT. These conditions range from genetic etiologies such as Kallmann syndrome and Klinefelter syndrome, to acquired causes such as testicular trauma. Conditions can be broadly classified as hypogonadotropic hypogonadism or hypergonadotropic hypogonadism, depending on whether there are concurrently elevated gonadotropins (follicle-stimulating hormone (FSH) and luteinizing hormone (LH)). The decision to initiate TRT in these cases is multifaceted, contributing to the challenge of formulating clear guidelines. In this review, we utilized online sources such as PubMed and Google Scholar to find relevant literature, using key words such as testosterone therapy, adolescents and hormone replacement and hypogonadism in adolescents. This narrative review explores existing literature on TRT in adolescents and young men, encompassing common etiologies of hypogonadism in this population, available TRT therapies, and management and surveillance protocols. Furthermore, it addresses the evolving field of TRT in transgender youth. This study underscores the necessity for additional clinical investigations to explore emerging TRT therapies and establish clear surveillance guidelines tailored to this population.

In response to international sanctions, Russia has restructured its hydrocarbon commerce through trade deflection, redirecting exports from sanctioning to non-sanctioning countries. Theresearch aimed to analyze hydrocarbon trade deflection under theRussia–Ukraine conflict within thecontext of theChina–Russia Strategic Partnership and BRICS, and to assess therestructuring of Russia’s crude oil and natural gas supply chains from 2020 to 2023. Two questions were addressed: Whether trade deflection shifted towards non-sanctioning countries, including China and other BRICS countries; whether Russia’s oil and gas supply chains were restructured towards these regions? Design incorporates themethod developed by theauthor which generates and utilizes an integrated database of Bill of Lading and export data to analyze supply-chain trade restructuring, identifying specific shifts in trade flows by product, country, and enterprises. Findings reflected that after sanctions were imposed in early 2022, Russian hydrocarbon exports to sanctioning countries declined sharply, while exports to non-sanctioning countries, particularly China and India, increased significantly. Findings demonstrate theeffectiveness of trade deflection as a strategic response to sanctions. This strategy has mitigated theadverse impacts on Russian oil and gas industry, with significant increases in exports to China and India. TheComprehensive Strategic Partnership with China has helped secure a substantial market for Russian crude oil and increased China’s energy security. This study enhances understanding of trade deflection mechanisms and provides a framework for analyzing theinterplay between international trade, geopolitical strategies, and economic resilience. Geopolitical alliances and trade partnerships have ensured resilience and continuity in global trade. This shift indicates strategic diversification towards Asian markets and increased Central Asian involvement. BRICS engagement has provided Russia with a platform to advocate for energy security and challenge Western dominance in global energy governance. Future research should explore other supply-chain components and analyze trade within theBRICS+ group and Russia–China bilateral trade.

This essay builds upon previous work introducing the hermeneutic of Divine relationship, a lens by which systemically oriented Christian therapists can begin to understand the connections between the relational nature of God and their systemic worldview. Specifically, we explore what liberation theology has to offer each of the five domains of the hermeneutic of Divine relationship (i.e., God's nature, human nature, sin and suffering, reconciliation, and hope) and by doing so demonstrate how a revisioning of the hermeneutic of Divine relationship through a liberation theology lens helps move the hermeneutic forward in its ability to aid all systemically oriented Christian therapists with their personal and professional integration. Additionally, this essay explores what a training course on the hermeneutic of Divine relationship could look like and presents a prototype curriculum for training on the hermeneutic of Divine relationship and personal/professional integration for systemically oriented Christian therapists.

Social workers are well positioned to meet the needs of the immigrant population in the United States (U.S.) and social workers across all fields and specializations should both feel competent and have the appropriate skills to work with immigrant clients. In this paper, we provide context around the immigrant population in the U.S. and discuss social work's role in helping immigrants, and the role of the MSW degree in helping to prepare social workers to work with immigrants. Using publicly available data on MSW school websites, we analyze the prevalence of courses that specifically focus on immigrants or immigration. We found a lack of semester-long immigrant-specific courses in that only 12% of the programs offered these courses. We also noted the geographic clustering of some programs that offer these courses. We propose that schools do one of the following depending on their current course offerings, faculty expertise, and other resources: ensuring that basic content and case examples about immigrants are included in foundational social work courses, and when feasible or appropriate create elective courses, or create a concentration for those wishing to specialize in social work practice with immigrants.

In this paper, for a bounded linear operator defined on a complex Banach space of infinite dimension, we consider the set of isolated points in its approximate point spectrum, which are eigenvalues of finite multiplicity; this set can be equal to the spectrum of the operator but without its upper semi-Fredholm spectrum, and this relation or equality defines in the literature a new spectral property called the property $ (\omega{ \pi }) $ and is a generalization of the classical a-Weyl theorem. We establish some characterizations and consequences about the property $ (\omega{ \pi }) $, some with topological aspects. Furthermore, we study this property through the Riesz functional calculus. Part of the spectral structure of a linear operator verifying property $ (\omega{ \pi }) $ is described, obtaining some associated properties.

Abstract SARS-CoV-2 caused the pandemic situation experienced since the beginning of 2020, and many countries faced the rapid spread and severe form of the disease. Mechanisms of interaction between the virus and the host were observed during acute phase, but few data are available when related to immunity dynamics in convalescents. We conducted a longitudinal study, with 51 healthy donors and 62 COVID-19 convalescent patients, which these had a 2-month follow-up after symptoms recovery. Venous blood sample was obtained from all participants to measure blood count, subpopulations of monocytes, lymphocytes, natural killer cells and dendritic cells. Serum was used to measure cytokines, chemokines, growth factors, anti-N IgG and anti-S IgG/IgM antibodies. Statistic was performed by Kruskal–Wallis test, and linear regression with days post symptoms and antibody titers. All analysis had confidence interval of 95%. Less than 35% of convalescents were anti-S IgM+, while more than 80% were IgG+ in D30. Anti-N IgG decreased along time, with loss of seroreactivity of 13%. Eosinophil count played a distinct role on both antibodies during all study, and the convalescence was orchestrated by higher neutrophil-to-lymphocyte ratio and IL-15, but initial stages were marked by increase in myeloid DCs, B1 lymphocytes, inflammatory and patrolling monocytes, G-CSF and IL-2. Later convalescence seemed to change to cytotoxicity mediated by T lymphocytes, plasmacytoid DCs, VEGF, IL-9 and CXCL10. Anti-S IgG antibodies showed the longest perseverance and may be a better option for diagnosis. The inflammatory pattern is yet present on initial stage of convalescence, but quickly shifts to a reparative dynamic. Meanwhile eosinophils seem to play a role on anti-N levels in convalescence, although may not be the major causative agent. We must highlight the importance of immunological markers on acute clinical outcomes, but their comprehension to potentialize adaptive system must be explored to improve immunizations and further preventive policies.
