Introduction/aims: If myasthenia gravis (MG) symptoms are inadequately controlled, patients may experience exacerbations or life-threatening myasthenic crises. Patients with inadequately controlled MG symptoms tend to be treated with chronic intravenous immunoglobulin (IVIg) therapy and/or multiple immunosuppressant therapies (ISTs). This study aimed to examine disease burden, healthcare resource utilization, and associated costs in these patients.

Background: The CoVID pandemic and the associated lockdown had a significant impact on mental health services. Inpatient services faced the challenge of offering acute psychiatric while implementing strict infection control measures. There is, however, a lack of studies investigating the use of coercive measures during the pandemic and their relation to hospitalizations and symptom severity.

Many Black educators in the United States demonstrate a political clarity about white supremacy and the racialized harm it cultivates in and out of schools. We highlight the perspectives of some of these educators and ask, (1) How do they articulate the need to protect Black children? and (2) What mechanisms of protection do they enact in their classrooms and schools? Through further elaborating the politicized caring framework, our analyses show how Black educators disrupt the racialized harm produced within schools to instead (re)position Black students as children worthy of protection via caring relationships, alternative discipline policies, and other interpersonal and institutional mechanisms. This study has implications for teaching, teacher education, and how the "work" of teachers is conceptualized and researched.

Failure to improve achievement in K-12 science for racially minoritized students and students living in poverty continues to challenge the inclusionary rhetoric of . Science education researchers, teacher educators, and educators must consider the racialized and classed inequalities that continue to limit students' opportunities to learn. To achieve this, we must be able to conceptualize sociopolitical pedagogical approaches and learn from empirical examples of science teachers who consciously attend to their students' realities in empowering rather than deficit-oriented ways.

Literature is limited comparing induction immunosuppression in pediatric liver transplant (LTx) recipients. This is a single-center, retrospective cohort study of primary pediatric liver transplants at our center between 2005 and 2016 who received either basiliximab (BSX) or rabbit anti-thymocyte globulin (rATG) induction. Maintenance immunosuppression consisted of tacrolimus ± a corticosteroid taper.

Public schools in the United States have struggled to determine whether their mandate is simply knowledge transmission or includes the development and well-being of the whole child. Contemporary realities of resegregation and inequality have prompted many districts to embrace this latter notion and consider the Full Service Community Schools (FSCSs) model. In this paper, we examine a school district's FSCS initiative as implemented at a predominately Black middle school and a racially heterogeneous high school.

Background And Purpose: this paper examines the impact of demographic change from 2007 to 2021 on the total cost of stroke in Ireland and analyses potential impacts of expanded access to stroke unit care and thrombolytic therapy on stroke outcomes and costs.

Methods: total costs of stroke are estimated for the projected number of stroke cases in 2021 in Ireland. Analysis also estimates the potential number of deaths or institutionalised cases averted among incident stroke cases in Ireland in 2007 at different rates of access to stroke unit care and thrombolytic therapy.

Background: Many countries are developing national audits of stroke care. However, these typically focus on stroke care from acute event to hospital discharge rather than the full spectrum from prevention to long-term care. We report on a comprehensive national audit of stroke care in the community and hospitals in the Republic of Ireland.

Background: Although stroke is recognised as a major factor in admission to nursing home care, data is lacking on the extent and nature of the disabilities and dependency in nursing homes arising from stroke. A national study conducted in nursing homes can quantify the number of residents with stroke in nursing homes, their disability and levels of dependency.

Methods: A cross-sectional survey research design was used.

S100beta is an astrocyte-derived uritotrophic' cytokine which has been implicated in the pathogenesis of Alzheimer's disease. S100beta overexpression by plaque-associated astrocytes correlates with growth of abnormal (strophic') neurites in beta-amyloid plaques, one of the major neuropathological hallmarks of Alzheimer's disease. As the characteristic neuropathological changes of Alzheimer's disease are virtually universal in middle-aged Down's syndrome patients, studies of Down's syndrome patients provide a unique opportunity to investigate the pathophysiological processes underlying the development of Alzheimer-type neuropathological changes.

Diffuse axonal injury (DAI) in the central nervous system is a common cause of post-traumatic coma and may result in varying degrees of disability up to and including the vegetative state. Experimental studies in man and animals have previously relied upon semi-quantitative grading systems for determining the relationship between the extent of DAI and the clinical features of patients. Using beta-amyloid precursor protein immunocytochemistry for the detection of DAI in sections of corpus callosum from 15 cases of fatal head injury, we have developed a quantitative image analysis technique for the assessment of axonal injury.

1. Alzheimer's disease is a heterogeneous disorder that may be caused by genetic or environmental factors or by a combination of both. Abnormalities in chromosomes 1, 14, and 21 have all been implicated in the pathogenesis of the early-onset form of the disease, while the epsilon 4 allele of the apolipoprotein E gene (on chromosome 19) is now recognized as a risk factor for early- and late-onset sporadic and familial Alzheimer's disease.

Chronic overexpression of the neurite growth-promoting factor S100beta has been implicated in the pathogenesis of neuritic plaques in Alzheimer's disease. Such plaques are virtually universal in middle-aged Down's syndrome, making Down's a natural model of Alzheimer's disease. We determined numbers of astrocytes overexpressing S100beta, and of neurons overexpressing beta-amyloid precursor protein (beta-APP), and assayed for neurofibrillary tangles in neocortex of 20 Down's syndrome patients (17 weeks gestation to 68 years).

Activated microglia overexpressing interleukin-1 (IL-1) are prominent neuropathological features of Alzheimer's disease. We used computerized image analysis to determine the number of IL-1 alpha-immunoreactive (IL-1 alpha +) microglia in cytoarchitectonic layers of parahippocampal gyrus (Brodmann's area 28) of Alzheimer and control patients. For cortical layers I and II, the numbers of IL-1 alpha + microglia were similar in Alzheimer and control patients.
