Working the edges of Posthuman disability studies: theorising with disabled young people with life‐limiting impairments

This paper is built upon an assumption: that social theory can be generated through a meaningful engagement with a co‐researcher group of disabled young people. Our co‐researchers are theoretical provocateurs and theorists in their own right who, through their activism and writing, are challenging us to reconsider the meaning of life, death and disability. Their work on our funded Economic and Social Research Council (ESRC) project has enabled us to consider the promise and potential of humanist and posthuman epistemologies, theories, methodologies, interventions and activisms. The paper introduces the research, the authors of this paper (academics and co‐researchers) and then explores three layers of analysis that work the edges of posthuman thinking; sovereign and assembled selves; affects and desires; mourning and affirmation. We conclude by asserting that as a research team we are engaging with a DisHuman approach to theory and activism: one that blends the pragmatics of humanism with posthuman possibilities.     

Middle Meningeal Artery Embolization Using Combined Particle Embolization and n-BCA with the Dextrose 5% in Water Push Technique for Chronic Subdural Hematomas: A Prospective Safety and Feasibility Study

BACKGROUND AND PURPOSE:Embolization of the middle meningeal artery for treatment of refractory or recurrent chronic subdural hematomas has gained momentum during the past few years. Little has been reported on the use of the n-BCA liquid embolic system for middle meningeal artery embolization. We present the technical feasibility of using diluted n-BCA for middle meningeal artery embolization.MATERIALS AND METHODS:We sought to examine the safety and technical feasibility of the diluted n-BCA liquid embolic system for middle meningeal artery embolization. Patients with chronic refractory or recurrent subdural hematomas were prospectively enrolled from September 2019 to June 2020. The primary outcome was the safety and technical feasibility of the use of diluted n-BCA for embolization of the middle meningeal artery. The secondary end point was the efficacy in reducing hematoma volume.RESULTS:A total of 16 patients were prospectively enrolled. Concomitant burr-hole craniotomies were performed in 12 of the 16 patients. Two patients required an operation following middle meningeal artery embolization for persistent symptoms. The primary end point was met in 100% of cases in which there were no intra- or postprocedural complications. Distal penetration of the middle meningeal artery branches was achieved in all the enrolled cases. A 7-day post–middle meningeal artery embolization follow-up head CT demonstrated improvement (>50% reduction in subdural hematoma volume) in 9/15 (60%) patients, with 6/15 (40%) showing an unchanged or stable subdural hematoma. At day 21, available CT scans demonstrated substantial further improvement (>75% reduction in subdural hematoma volume).CONCLUSIONS:Embolization of the middle meningeal artery using diluted n-BCA and ethiodized oil (1:6) is safe and feasible from a technical standpoint. The use of a dextrose 5% bolus improves distal penetration of the glue.

Despite traditional treatment with surgical evacuation, chronic subdural hematomas (cSDHs) tend to have an indolent course with frequent recurrences.¹ In recent years, embolization of the middle meningeal artery (MMA) for treatment of refractory or recurrent cSDH has gained momentum, with recent literature showing a significant reduction in the size of the cSDH as well as lower rates of recurrence.² The primary endovascular techniques used to date have involved the use of polyvinyl alcohol particles (PVA) and Onyx liquid embolic (ethylene-vinyl alcohol dissolved in dimethyl-sulfoxide; Medtronic). Another commonly used liquid embolic agent in the neurointerventional area is n-BCA, which is a liquid adhesive that polymerizes rapidly on contact with ionic substances and can be injected to achieve permanent vessel occlusion. The rates of polymerization and flow and the penetration depth can be modified using varying amounts of ethiodized oil as well as concurrent infusion of dextrose 5% in water (D5W) during n-BCA (Trufill, Cordis Neurovascular) injection (D5W-push technique).³ Data on the use of n-BCA as an embolic agent in cases of cSDH are extremely limited. Herein, we sought to study the safety and technical feasibility of using diluted n-BCA for embolization of the MMA for cSDHs.     

Developing collaborative approaches to international research: Perspectives of new global health researchers

Within a global context of growing health inequities, the fostering of partnerships and collaborative research have been promoted as playing a critical role in tackling health inequities and health system problems worldwide. Since 2004, the Canadian Coalition for Global Health Research (CCGHR) has facilitated annual Summer Institutes for new global health researchers aimed at strengthening global health research competencies and partnerships among participants. We sought to explore CCGHR Summer Institute alumni perspectives on the Summer Institute experience, particularly on the individual research pairings of Canadian and low- and middle-income countries researchers that have characterised the program. The results reveal that the Summer Institute offered an enriching learning opportunity for participants and worked to further their collaborative projects through providing dedicated one-on-one time with their international research partner, feedback from colleagues from around the world and mentorship by more senior researchers. Positive individual relationships among researchers, as well as the existence of institutional collaborations, employer and funding support, and agendas of local and national politicians were factors that have influenced the ongoing collaboration of partners. There is a need to more fully examine the interplay between individual and institutional-level collaborations, as well as their social and political contexts.     

Utilization of social workers in home care: An analysis of service use

ABSTRACT

Social workers are well positioned to address mental health complications impacting home care populations, yet social work has one of the lowest utilization rates of offered home care supports in Ontario. This study analyzed care plan data of frontline in-home social work services. Results identified adjustment to illness as the most common category and that seniors required significantly fewer visits and days on service than non-seniors. Most patients were able to accomplish their social work-based goals. Results highlight a need for further research and for capitalizing on the untapped potential value of social work home care services for patients.     

Dysfunctional RNA-binding protein biology and neurodegeneration in experimental autoimmune encephalomyelitis in female mice

Altered stress granule (SG) and RNA-binding protein (RBP) biology have been shown to contribute to the pathogenesis of several neurodegenerative diseases, yet little is known about their role in multiple sclerosis (MS). Pathological features associated with dysfunctional RBPs include RBP mislocalization from its normal nuclear location to the cytoplasm and the formation of chronic SGs. We tested the hypothesis that altered SG and RBP biology might contribute to the neurodegeneration in experimental autoimmune encephalomyelitis (EAE). C57BL/6 female mice were actively immunized with MOG_35-55 to induce EAE. Spinal cords were examined for mislocalization of the RBPs, heterogeneous nuclear ribonucleoprotein A1 (hnRNP A1) and TAR-DNA binding protein-43 (TDP-43), SGs, neurodegeneration (SMI-32), T cells (CD3), and macrophages (CD68). In contrast to naive mice, mice with EAE showed SG formation (p < 0.0001) and mislocalization of hnRNP A1 (p < 0.05) in neurons of the ventral spinal cord gray matter, which correlated with clinical score (R = 0.8104, p = 0.0253). In these same areas, there was a neuronal loss (p < 0.0001) and increased SMI-32 immunoreactivity (both markers of neurodegeneration) and increased staining for CD3⁺ T cells and IFN-gamma. These findings recapitulate the SG and RBP biology and markers of neurodegeneration in MS tissues and suggest that altered SG and RBP biology contribute to the neurodegeneration in EAE, which might also apply to the pathogenesis of MS.
