Introduction to the Anti-Racism Virtual Issue of the Journal of Occupational Science

The anti-racism virtual issue of the Journal of Occupational Science (JOS) came about after the Editorial Board expressed its commitment to anti-racist work, publishing the position statement ‘A Pledge to Mobilize Against Racism’ (Stanley et al., 2020). In this statement, the Board promised to republish a collection of articles to call attention to racism and its impact on individuals’ doing and society. The intent is to stimulate critical reflection on the contribution occupational scientists can make to exposing and countering racism in everyday doing. As such, the anti-racism virtual issue helps meet a pressing need to recognize the power of occupation in shaping and reproducing social ideologies, attitudes, and behaviors. We, the authors, urge all occupational scientists to build on this knowledge and continue learning about racism to better understand and address how its different dimensions manifest through occupation and everyday life

Surfactant protein A and D polymorphisms and methylprednisolone pharmacogenetics in donor lungs

Objective: Surfactant proteins A and D are important molecules involved in lung allograft innate immunity. Genetic polymorphisms of surfactant proteins A and D are associated with various lung diseases. In this study, surfactant protein A and D expression responses were investigated during pharmacogenetics upon methylprednisolone treatment as observed during lung transplantation. Methods: A human cell line (NCI-H441) and precision-cut lung slices from 16 human donors were incubated with methylprednisolone, and surfactant protein A1, surfactant protein A2, and surfactant protein D messenger RNA and surfactant protein A protein expression were assayed. Surfactant protein A1, A2, and D polymorphisms and surfactant protein A gene and protein expressions were determined. Results: In NCI-H441 cells, methylprednisolone treatment at 10−5 M and 10−6 M reduced surfactant protein A1 and surfactant protein A2 messenger RNA and surfactant protein A protein expression (P <.05). A pharmacogenetic relationship was observed in human donor precision-cut lung slices between the surfactant protein A2 (1Ax) variants: Surfactant protein A1, A2, and D messenger RNA expression were greater for 1A0 versus 1A1 (P <.05); surfactant protein A1/surfactant protein A2 genotype 6A26A2/1A01A0 (n = 5) showed greater surfactant protein A1, A2, and D messenger RNA expression and surfactant protein A protein expression compared with the other surfactant protein A1/surfactant protein A2 genotypes (n = 11) (P <.05). Conclusions: The surfactant protein A genotype and methylprednisolone stimuli influence donor lung surfactant protein A and D expression. Lungs carrying the surfactant protein A2 variant 1A0 have a greater expression of surfactant protein A when treated with methylprednisolone. Surfactant protein A polymorphisms could be used to personalize immunosuppressive regimens

Rethinking Design : A Dialogue on Anti-Racism and Art Activism from a Decolonial Perspective

This chapter focuses on feminist anti-racist activism from a decolonial perspective in the field of cultural production. The authors analyze racialized and racist representations in Finland, and propose interventions from a decolonial perspective. We propose a number of strategies in the field of representation to create non-stereotypical and demeaning racist images, in order to challenge and transform racialized representational practices. We analyze our experience of Finland through concepts such as the white savior complex, white fragility and racial illiteracy to grasp the specificity of the ways through which racism is given meaning and acted upon.Peer reviewe

Donor Surfactant Protein A2 Polymorphism and Lung Transplant Survival.

Purpose Gene polymorphisms of surfactant proteins, key players in lung innate immunity, have been associated with various lung diseases. The aim of this study was to investigate the potential association between variations within the SP-A gene of the donor lung allograft and recipient post-transplant outcome. Methods Lung-Tx pts (n=192) were prospectively followed by PFTs, bronchoscopies with BAL and biopsies. Donor lungs were assayed for SP-A1 (6An) and SP-A2 (1An) gene polymorphism by using the pyrosequencing method. Unadjusted and adjusted stratified Cox survival models are reported. Results SP-A1 and SP-A2 genotype frequency and lung transplant recipient and donor characteristics as well as the cause of death are noted. Recipients were grouped per donor SP-A2 variants. Individuals that received lungs from donors with the SP-A2 1A0 (n=102) versus 1A1 variant (n=68) or SPA2 genotype 1A01A0 (n=54) versus 1A0A1 (n=38) had greater survival at one year (logrank p<0.025). No significant association was noted for SP-A1 variants. Stratified adjusted survival models for one year survival and diagnosis showed a reduced survival for 1A1 variant and the 1A01A1 genotype. Furthermore, when survival was conditional on one year survival no significance was observed, indicating that the survival difference were due to the first year's outcome associated with the 1A1 variant. Conclusion Donor lung SP-A gene polymorphisms are associated with post-transplant clinical outcome. Lungs from donors with the SP-A2 variant 1A1 had a reduced survival at one year. The observed donor genetic differences, via innate immunity relate to the post-transplant clinical outcome.PURPOSE: Gene polymorphisms of surfactant proteins, key players in lung innate immunity, have been associated with various lung diseases.

National belonging post‐referendum: Britons living in other EU Member States respond to “Brexit”

Following the EU Referendum, this paper tracks how pro‐Remain British migrants living in other EU Member States expressed a sense of shame and dislocation in relation to their national identity. Developed from a survey of 909 British nationals living in other EU Member States, it hopes to make a timely intervention into wider debates about privileged migration, Britishness, citizenship and belonging. First, it outlines a new articulation of the “bad Britain” discourse among emigrants, who saw the UK as increasingly characterised by xenophobia and insularity. Second, it seeks to understand how their national identity and sense of belonging was being renegotiated post‐referendum through a lens attentive to the cultural politics of emotion and innocence as an operation of whiteness

Genetic Variants of Surfactant Proteins A, B, C, and D in Bronchopulmonary Dysplasia

BPD_28D (O2 dependency at 28 days of life) and BPD_36W (O2 dependency at 36 wks post-menstrual age) are diseases of prematurely born infants exposed to mechanical ventilation and/or oxygen supplementation. In order to determine whether genetic variants of surfactant proteins (SPs-A, B, C, and D) and SP-B-linked microsatellite markers are risk factors in BPD, we performed a family based association study using a Greek study group of 71 neonates (<30 wks gestational age) from 60 families with, 52 BPD_28D and 19 BPD_36W, affected infants. Genotyping was performed using newly designed pyrosequencing assays and previously published methods. Associations between genetic variants of SPs and BPD subgroups were determined using Transmission Disequilibrium Test (TDT) and Family Based Association Test (FBAT). Significant associations (p ≤ 0.01) were observed for alleles of SP-B and SP-B-linked microsatellite markers, and haplotypes of SP-A, SP-D, and SP-B. Specifically, allele B-18_C associated with susceptibility in BPD_36W. Microsatellite marker AAGG_6 associated with susceptibility in BPD_28D/36W group. Haplotype analysis revealed ten susceptibility and one protective haplotypes for SP-B and SP-B-linked microsatellite markers and two SP-A-SP-D protective haplotypes. The data indicate that SP loci are linked to BPD. Studies in different study groups and/or of larger sample size are warranted to confirm these observations and delineate genetic background of BPD subgroups

The Central Clock Neurons Regulate Lipid Storage in Drosophila

A proper balance of lipid breakdown and synthesis is essential for achieving energy homeostasis as alterations in either of these processes can lead to pathological states such as obesity. The regulation of lipid metabolism is quite complex with multiple signals integrated to control overall triglyceride levels in metabolic tissues. Based upon studies demonstrating effects of the circadian clock on metabolism, we sought to determine if the central clock cells in the Drosophila brain contribute to lipid levels in the fat body, the main nutrient storage organ of the fly. Here, we show that altering the function of the Drosophila central clock neurons leads to an increase in fat body triglycerides. We also show that although triglyceride levels are not affected by age, they are increased by expression of the amyloid-beta protein in central clock neurons. The effect on lipid storage seems to be independent of circadian clock output as changes in triglycerides are not always observed in genetic manipulations that result in altered locomotor rhythms. These data demonstrate that the activity of the central clock neurons is necessary for proper lipid storage

Successful outcome of six-level cervicothoracic corpectomy and circumferential reconstruction: case report and review of literature on multilevel cervicothoracic corpectomy

The authors report the successful outcome of a six-level corpectomy across the cervico-thoracic spine with circumferential reconstruction in a patient with extensive osteomyelitis of the cervical and upper thoracic spine. To the authors’ knowledge, this is the first report of a corpectomy extending across six levels of the cervico-thoracic spine. Clinical relevance: the authors recommend anterior cage and plate-assisted reconstruction and additional posterior instrumentation using modern spinal surgical techniques and implants
