In recent years, researchers have worked closely with parents, teachers, other school staff, and external stakeholders to increase knowledge on ways to effectively teach children and adolescents with disabilities in mainstream school settings. State, national, and global directives have encouraged the implementation of research-based practices and contributed to advocacy efforts for students with and without disabilities. In a longitudinal comparative case study, Grima-Farrell (2017) responded to these movements by striving to enhance teacher knowledge on how to effectively implement and sustain the use of validated teaching approaches to maximise the student engagement and success of all students. This paper specifically reports on the school-based efforts of 6 experienced teachers as they strive to implement research-based practices to respond to the diverse needs of their students. Results are presented using the research-to-practice model (Grima-Farrell, 2017) as a conceptual framework for guiding instructional decision-making through the implementation and sustained use of validated educational research approaches.
The purpose of this research was to investigate leadership facilitating effective inclusive school practices. Data were collected from leaders at a complex multicultural school perceived by the system and local community as an inclusive school with a focus on quality education. A qualitative case study was used and data were collected over a 6-month period of immersion at the research site. Data included semistructured interviews with the head of special education and the school principal, observations of dialogical and behavioural data described within the lead researcher's reflective journal, and the documented operational structure of the school. The findings include insights into what the principal and head of special education believed inclusion to be, and how these leaders worked with staff to embed inclusive practices. The conclusion drawn from the study is that school leadership for inclusion involves making hard decisions. It is a complex and multifaceted act requiring consciously targeted effort, advocacy, and particular ways of leading. Inclusive practices need reinforcing by frequently articulated expectations, support, and acknowledgement that for all stakeholders inclusion is a constant journey toward a shared vision.
School leadership is critical to provide students with disabilities with opportunities to learn in inclusive schools. We summarise research about inclusive leadership, outlining factors that promoted and impeded inclusive schools in the United States. Next, we provide an example of a national collaboration between the Council of Chief State School Officers (CCSSO) and the Collaboration for Effective Educator Development, Accountability, and Reform (CEEDAR) Center that linked the Professional Standards for Educational Leaders (PSEL; National Policy Board for Educational Administration, 2015) to a supplemental guidance document, titled PSEL 2015 and Promoting Principal Leadership for the Success of Students With Disabilities. The latter illustrates what effective inclusive school leadership means for each of the 10 PSEL standards, and provides recommendations for improving leadership preparation and policy, including licensure. We also consider possible implications of this work for those in other countries, emphasising the need for widely understood and shared leadership practices and the need to link such practices to initial and ongoing leadership development.
In this paper, we explored various aspects of Canadian preservice elementary school teacher views about inclusive physical education. Based on prior work by Loreman (2014) that broadly examined preservice teacher views on inclusive education, in this study we looked specifically at inclusive physical education using a different sample of participants in the same program. Preservice teachers were asked a series of open-ended questions relating to their understandings, feelings of teaching self-efficacy, attitudes, and concerns relating to inclusive physical education in elementary school. Their responses reflected a strong focus on ability diversity (e.g., disability) and indicated that inclusive physical education means that all students should be part of the learning environment or that some should be excluded in roughly equal proportion. Depending on the curricular dimension, their self-perceived levels of preparedness ranged from low to high. The participants also presented a strong case for the necessity of resources available for the teaching of inclusive physical education.
Although researchers have developed evidence-based practices and identified other effective practices that show promise for improving outcomes for students with disabilities, these practices are all too frequently not used in inclusive classrooms. Some have posited that this research-to-practice gap may result because teachers lack confidence in these practices and do not find them feasible for use in their classrooms. More recently, researchers have begun to examine whether teacher education may contribute to this research-to-practice gap. We contend that teacher preparation is an important contributor to the research-to-practice gap, and discuss how teacher preparation might be changed to better prepare teachers to use effective practices in inclusive classrooms. Primary changes that are needed include identifying a set of high-leverage practices that serve as the core curriculum of teacher education and using a practice-based approach to systematically prepare future teachers to use these practices.
Directors of Student Teaching from the Western Canadian provinces participated in focus groups about the realities and decision-making processes around practicum for preservice teachers with disabilities. Results showed current standards, when applied rigidly, served to reify a static, homogenous, and unrealistic definition of ‘teacher’ that marginalises preservice teachers with disabilities. However, the effort of directors to challenge this notion of ‘teacher’, framed within the constructionist model of disability, gives hope for a more inclusive future teaching force.
To compare the epidemiology, clinical characteristics, and mortality of patients with bloodstream infections (BSI) caused by extended-spectrum β-lactamase (ESBL)-producing Escherichia coli (ESBL-EC) versus ESBL-producing Klebsiella pneumoniae (ESBL-KP) and to examine the differences in clinical characteristics and outcome between BSIs caused by isolates with CTX-M versus other ESBL genotypes
As part of the INCREMENT project, 33 tertiary hospitals in 12 countries retrospectively collected data on adult patients diagnosed with ESBL-EC BSI or ESBL-KP BSI between 2004 and 2013. Risk factors for ESBL-EC versus ESBL-KP BSI and for 30-day mortality were examined by bivariate analysis followed by multivariable logistic regression.
The study included 909 patients: 687 with ESBL-EC BSI and 222 with ESBL-KP BSI. ESBL genotype by polymerase chain reaction amplification of 286 isolates was available. ESBL-KP BSI was associated with intensive care unit admission, cardiovascular and neurological comorbidities, length of stay to bacteremia >14 days from admission, and a nonurinary source. Overall, 30-day mortality was significantly higher in patients with ESBL-KP BSI than ESBL-EC BSI (33.7% vs 17.4%; odds ratio, 1.64; P=.016). CTX-M was the most prevalent ESBL subtype identified (218 of 286 polymerase chain reaction-tested isolates, 76%). No differences in clinical characteristics or in mortality between CTX-M and non–CTX-M ESBLs were detected.
Clinical characteristics and risk of mortality differ significantly between ESBL-EC and ESBL-KP BSI. Therefore, all ESBL-producing Enterobacteriaceae should not be considered a homogeneous group. No differences in outcomes between genotypes were detected.
Asbestos bodies are the histological hallmarks of asbestos exposure. Both conventional and advanced techniques are used to evaluate abundance and composition in histological samples. We previously reported the possibility of using synchrotron X-ray fluorescence microscopy (XFM) for analyzing the chemical composition of asbestos bodies directly in lung tissue samples. Here we applied a high-performance synchrotron X-ray fluorescence (XRF) set-up that could allow new protocols for fast monitoring of the occurrence of asbestos bodies in large histological sections, improving investigation of the related chemical changes. A combination of synchrotron X-ray transmission and fluorescence microscopy techniques at different energies at three distinct synchrotrons was used to characterize asbestos in paraffinated lung tissues. The fast chemical imaging of the XFM beamline (Australian Synchrotron) demonstrates that asbestos bodies can be rapidly and efficiently identified as co-localization of high calcium and iron, the most abundant elements of these formations inside tissues (Fe up to 10% w/w; Ca up to 1%). By following iron presence, we were also able to hint at small asbestos fibers in pleural spaces. XRF at lower energy and at higher spatial resolution was afterwards performed to better define small fibers. These analyses may predispose for future protocols to be set with laboratory instruments.
Accurate discrimination of two morphologically similar species of Patella limpets has been facilitated by using qPCR amplification of species-specific mitochondrial genomic regions. Cost-effective and non-destructive sampling is achieved using a mucus swab and simple sample lysis and dilution to create a PCR template. Results show 100% concurrence with dissection and microscopic analysis, and the technique has been employed successfully in field studies. The use of highly sensitive DNA barcoding techniques such as this hold great potential for improving previously challenging field assessments of species abundance.
Clostridium difficile infection (CDI) has been extensively described in healthcare settings; however, risk factors associated with community-acquired (CA) CDI remain uncertain. This study aimed to synthesize the current evidence for an association between commonly prescribed medications and comorbidities with CA-CDI.
A systematic search was conducted in 5 electronic databases for epidemiologic studies that examined the association between the presence of comorbidities and exposure to medications with the risk of CA-CDI. Pooled odds ratios were estimated using 3 meta-analytic methods. Subgroup analyses by location of studies and by life stages were conducted.
Twelve publications (n=56,776 patients) met inclusion criteria. Antimicrobial (odds ratio, 6.18; 95% CI, 3.80–10.04) and corticosteroid (1.81; 1.15–2.84) exposure were associated with increased risk of CA-CDI. Among the comorbidities, inflammatory bowel disease (odds ratio, 3.72; 95% CI, 1.52–9.12), renal failure (2.64; 1.23–5.68), hematologic cancer (1.75; 1.02–5.68), and diabetes mellitus (1.15; 1.05–1.27) were associated with CA-CDI. By location, antimicrobial exposure was associated with a higher risk of CA-CDI in the United States, whereas proton-pump inhibitor exposure was associated with a higher risk in Europe. By life stages, the risk of CA-CDI associated with antimicrobial exposure greatly increased in adults older than 65 years.
Antimicrobial exposure was the strongest risk factor associated with CA-CDI. Further studies are required to investigate the risk of CA-CDI associated with medications commonly prescribed in the community. Patients with diarrhea who have inflammatory bowel disease, renal failure, hematologic cancer, or diabetes are appropriate populations for interventional studies of screening.
Interventions that prevent healthcare-associated infection should lead to fewer deaths and shorter hospital stays. Cleaning hands (with soap or alcohol) is an effective way to prevent the transmission of organisms, but rates of compliance with hand hygiene are sometimes disappointingly low. The National Hand Hygiene Initiative in Australia aimed to improve hand hygiene compliance among healthcare workers, with the goal of reducing rates of healthcare-associated infection.
We examined whether the introduction of the National Hand Hygiene Initiative was associated with a change in infection rates. Monthly infection rates for healthcare-associated Staphylococcus aureus bloodstream infections were examined in 38 Australian hospitals across 6 states. We used Poisson regression and examined 12 possible patterns of change, with the best fitting pattern chosen using the Akaike information criterion. Monthly bed-days were included to control for increased hospital use over time.
The National Hand Hygiene Initiative was associated with a reduction in infection rates in 4 of the 6 states studied. Two states showed an immediate reduction in rates of 17% and 28%, 2 states showed a linear decrease in rates of 8% and 11% per year, and 2 showed no change in infection rates.
The intervention was associated with reduced infection rates in most states. The failure in 2 states may have been because those states already had effective initiatives before the national initiative’s introduction or because infection rates were already low and could not be further reduced.
