Deweyan Reflections on Knowledge-Producing Schools
Authors: Schneider S.B. , Garrison Jim 
Published: February 2022

Background/Context Our article examines some of the philosophical underpinnings of knowledge-producing schools (KPS). KPS is an Australian initiative advanced by such researchers as Chris Bigum, Colin Lankshear, and Michael Knobel. Purpose/Objective/Research Question/Focus of Study We examine the epistemology and the theory of new literacy that KPS scholars put forth, which we strongly endorse, and address a lack of attention to embodiment and the emotions that KPS epistemology would seem to require. Our article is devoted to addressing this omission, which we frequently find in other approaches to literacy studies as well. Research Design We call on the philosophy of Deweyan pragmatism to provide a friendly critique and reconstruction of KPS epistemology. In doing so, we will rely on the perspective of Deweyan pragmatism supplemented by some of the insights of pragmatist feminism. Conclusions/Recommendations In our reconstruction of KPS, we offer a Deweyan performance epistemology that resembles the epistemology championed by KPS in some important ways, but by emphasizing the role of embodiment and emotion (“bodying”) in making meaning and making knowing, it allows us to better comprehend what it entails to be a member of a community of practice.
Echo Effects and Curriculum Change
Authors: Cornbleth Catherine 
Published: February 2022

Background/Context This project is framed by a critical pragmatism, which is evident in the questioning of how social conditions and events outside schools influence classroom practice and in exploring the question of who benefits, collectively and individually, socially and politically, as well as pedagogically. Purpose/Objective/Research Question/Focus of Study The intent of this work is to better our understanding of the school-society nexus generally and, more specifically, of curriculum practice and change in relation to societal conditions and events. This goal is pursued by means of analysis of relevant research to illustrate what might be called “echo effects” in order to account for changes in curriculum policy and practice in response to external press. Research Design Methodologically, this is an analytic article that reexamines data and interpretations from several relevant research projects. In addition to media research relevant to the conception of “echo,” four cases/studies provide illustration of echoes and apparent “echo effects” on curriculum policy and/or practice: state-level curriculum policymaking; school administrator perceptions and practices regarding censorship challenges; teachers’ responses to new or increased state testing in academic subject areas; and teachers’ responses to the terrorist attacks of September 11, 2001, and their aftermath. Conclusions/Recommendations Echoes and apparent echo effects on curriculum policy and classroom practice are important because they demonstrate one means by which events and “social forces” enter into public and professional discourses, and that discourses matter, in part by framing issues, focusing attention, and rendering legitimacy. Echo effects appear to be dependent on the echoes being received or “heard” and on the extent to which they are perceived or interpreted in ways (1) compatible with one's values and priorities, and (2) feasible to act on in current circumstances (given one's assessment of the situation, one's political and professional skills, and so forth). Next steps include examining the conditions under which echo effects are stronger or weaker and perhaps attempting to manage (e.g., deflect) the echoes themselves. Notably, the cases of echo effects offered here all contribute, though in varying degrees, to the narrowing of curriculum policy and practice. The cumulative curriculum effects of these echoes appear to sustain more than challenge the status quo. With greater awareness and understanding of how external influences enter in and operate, we are better able to raise questions and attempt to reshape curricular and other educational issues, not merely to participate in the debates on terms set by others or to be swept along by default.
Learning Motivation: The Role of Opportunity
Authors: Mccaslin Mary 
Published: February 2022

Background/Context Student motivation typically has been studied as it relates to extrinsic (e.g., reinforcement) and intrinsic (e.g., choice) sources of influence. Our observation of Grades 3–5 classrooms engaged in Comprehensive School Reform (CSR), however, unexpectedly indicated that opportunities for both rewards and choice were scarce. This study sought to better understand what might influence student motivation in these settings. Purpose The purpose of this study was (1) to listen to students to understand how they talked about school, classroom learning, and related issues that appeared to matter to them; (2) to observe students in their daily negotiations of school tasks, challenges, and relationships; (3) to then design survey measures to capture these students’ perspectives and motivational dynamics; and (4) to determine if the apparent student motivational dynamics generalized to other students in similar contexts. Research Design The author conducted a participant observation project in a single school, engaged in school reform, that served students living in poverty. The study involved frequent (N = 45) school visits from the spring of one school year through the spring of the next. The goal was to generate hypotheses about what might inform student motivational dynamics in the context of CSR schools. Conclusions/Recommendations The central theme to emerge from the participant observation study was the key role of opportunity in students’ learning motivation and motivation to learn. Motivational opportunities were organized into three types: supports, challenges, and threats. Each was represented in survey measures that appear useful in capturing the motivational dispositions and beliefs about school of students in Grades 3–5 in similar contexts.
Teacher Support of Student Autonomy in Comprehensive School Reform Classrooms
Authors: Bozack Amanda Rabidue , Vega Ruby , Mccaslin Mary , Good Thomas L. 
Published: February 2022

Background/Context Research in the self-determination theoretical (SDT) tradition indicates that teachers’ autonomy-supportive behaviors result in students’ greater perceived academic competence, better academic performance, and increased achievement. This study describes autonomy-supportive teacher behaviors in schools participating in Comprehensive School Reform (CSR). Research Question In a 2006 pilot study to determine if autonomous opportunities occurred in CSR classroom contexts, Bozack, McCaslin, and Good identified the presence or absence of autonomy-supporting teaching in their written narratives of classroom practices. The current study moves that pilot research forward by asking, Are autonomy-supportive teaching practices present? And if so, what is the nature of the teacher-student interactions in these classrooms? Population The sample consisted of 696 intervals of field notes from 106 classroom observations in five CSR schools in Grades 3, 4, and 5. Research Design Comprehensive School Reform Classroom Observation System (CSRCOS) observation field notes were analyzed using the Autonomy Supportive Behavior Instrument (ASBI). The scale was developed based on previous SDT research suggestions about how teachers can foster autonomy in the classroom. Conclusions Results indicated that all eight teaching practices suggested by SDT were present in our field notes; however, their frequency and form varied considerably from SDT expectations. Students had many opportunities to manipulate objects, but in half of the codes, we found that students were using the same objects for the same tasks in the same way, suggesting that there was little opportunity for students to choose how they wanted to work with objects. Students had many opportunities to talk. Teachers prompted and guided student learning most of the time, yet rarely helped students to relate ideas and concepts from one topic to another or from one lesson to another. Opportunities for student choice were infrequent, and when our field notes included verbal exchange, we found that teachers consistently responded to student questions and student-initiated dialogue. We rarely identified explicit instances of encouragement or teachers engaging the experiences, expertise, or perspective of students.
Herniated superficial lipomas in gluteal and thigh support areas: a special clinical ultrasound presentation
Authors: Whittle Carolina , Fajre Ximena , Silva Catalina , Castro Alex 
Published: February 2022

Background Lipomas are the most frequent benign tumor. They have been described as soft, well-defined, slow-growing palpable masses, and classified as deep or superficial. Purpose To present the clinical and ultrasound findings of herniated superficial subcutaneous lipoma (HSL), located in pressure/support areas, not previously described. Material and Methods A seven-year retrospective review was performed. Patients with a preoperative high-resolution ultrasound (HRUS) diagnosis of HSL archived in the computational system and histological study information were selected. Results A total of 37 patients (mean age = 46 years) were recruited. The clinical diagnoses were “lipoma” or “suspected lipoma” in just 46% of the cases. This was three times more frequent in women. Tumors were located mainly in the gluteal (38%) and proximal thigh areas (35%). Clinically, all patients showed small, soft, rounded skin nodules. On HRUS, they appear as lipomatous tumors that protruded, compressed, and thinned the covering dermal layer. The subcutaneous portion was bigger than the herniated part, with an iceberg image. Conclusion HSL in support areas have a special clinical ultrasound presentation, not previously described. It is important to recognize them for a proper diagnosis and treatment, especially because they clinically may present as small superficial lesions; however, they are associated with a larger subcutaneous portion (iceberg image). It is probable that an estrogen influence on the adipose tissue can be suspected because of the female predominance.

Published: February 2022

Background: Platelet-rich plasma (PRP) is gaining large interest in clinical practice as a minimally invasive injective treatment for knee osteoarthritis (OA). Different preparation methods are available, and the presence of leukocytes, deemed detrimental in some preclinical studies, is one of the most debated aspects regarding PRP efficacy. Purpose: To compare the safety and effectiveness of leukocyte-rich PRP (LR-PRP) and leukocyte-poor PRP (LP-PRP) for the treatment of knee OA. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 192 patients with symptomatic knee OA (Kellgren-Lawrence grade 1-3) were randomly allocated to 3 weekly injections of LR-PRP or LP-PRP. LP-PRP was obtained with a filter for leukodepletion. LR-PRP and LP-PRP were divided into aliquots of 5 mL, with a mean platelet concentration of 1146.8 × 109/L and 1074.9 × 109/L and a mean leukocyte concentration of 7991.4 × 106/L and 0.1 × 106/L, respectively. Patients were evaluated at baseline and thereafter at 2, 6, and 12 months for the primary outcome, the International Knee Documentation Committee (IKDC) subjective score; and for secondary outcomes, the Knee injury and Osteoarthritis Outcome Score (KOOS) subscales, EuroQol–visual analog scale (EQ-VAS), and Tegner score. Results: No differences between groups were observed in terms of absolute values or improvement of the clinical scores across all follow-up intervals. The mean IKDC subjective score at baseline and 12 months improved from 45.6 to 60.7 in the LR-PRP group as compared with 46.8 to 62.9 in the LP-PRP group ( P = .626). No severe adverse events were described in either group, although 15 mild adverse events (knee pain or swelling) were reported: 12.2% for LR-PRP and 4.7% for LP-PRP ( P = .101). No statistically significant difference was also found between LR-PRP and LP-PRP in terms of failures (7.8% vs 3.5%, P = .331). Conclusion: This double-blind randomized trial showed that 3 intra-articular LR-PRP or LP-PRP injections produced similar clinical improvement in the 12 months of follow-up in patients with symptomatic knee OA. Both treatment groups reported a low number of adverse events, without intergroup differences. The presence of leukocytes did not significantly affect the clinical results of PRP injections.

Published: February 2022

Purpose: The COVID19 pandemic has caused a redistribution of hospital resources. Prioritization strategies are needed in order to organize elective surgeries. We compared the new Medically Necessary Time-Sensitive score (MeNTS) and its factors (disease, procedure, and patient factors) between operated and deferred cases, and also to a subjective priority scale in the Urology department. Methods: The MeNTS score and a subjective prioritization scale were prospective applied to all patients included on the surgical waiting list from March 10 to September 9, 2020. Mann-Whitney U test was used to compare MeNTS scores between operated and non-operated groups. Kruskal-Wallis test was used to compare MeNTS scores between three subjective priority groups. Results: A total of 150 cases were operated while 100 were deferred. Median total MeNTS score in the operated group was 39.5 whereas in the non-operated group it was 38 ( p = 0.135). Median disease factors score was 9.5 in the operated group and 11 in the non-operated group( p = 0.033). Median procedure factors score was 10 in both groups ( p = 0.02). Median patient factors score was 17 in the operated group and 18 in the non-operated group ( p = 0.210). Disease factors displayed a significant difference between the three subjective priority groups Conclusions: Total MeNTS score does not show significant differences between operated and non-operated patients. However, we demonstrate a relationship between MeNTS disease factors and the operated group as well as with the subjective priority scale.

Published: February 2022

Objective The effectiveness of compulsory treatment orders (CTO) in psychiatric practice is an area in need of evidence. There are no recent New Zealand publications on outcomes for patients under CTOs. This study examined the association between CTOs and subsequent rehospitalisation for patients with schizophrenia or related disorders. Method Two year outcome data for 326 consecutive patients discharged in 2013 and 2014 was obtained from the Programme for the Integration of Mental Health Data database. Regression analyses were performed with rehospitalisation as the main outcome. Results For the 54% of patients discharged under CTOs, rehospitalisation was 2–4 times more likely for the CTO group than for voluntary patients. Patients under CTOs also spent longer in hospital post index admission (IA). However, patients placed under CTOs during IA stayed longer than those under CTOs prior to IA. Ethnicity did not contribute significantly to any of the findings. Conclusion This study did not show that patients under CTOs were associated with subsequent reduced resource use. The subgroup analysis suggested that studies with a longer follow-up period may provide better insight into the utility of CTOs.

Published: February 2022

Introduction: Bhutanese refugees may exhibit psychological distress (PD), post-traumatic stress (PTS), and suicidal ideation (SI), but little is known about predictors of these mental health problems. Purpose: To examine rates and predictors of PD, PTS, and SI among Bhutanese refugees. Methods: Cross-sectional correlational study of 209 Bhutanese refugees in Midwestern United States. Data were collected using the Hopkins Symptom Checklist/Nepali version and Refugee Health Screener-15/PTS subscale and then analyzed using simultaneous multiple regression. Results: Rates of PD, PTS, and SI were 18.7%, 8.1%, and 7.7%, respectively. Significant predictors of PD were a history of mental health treatment ( p<.001) and fewer years of schooling ( p = .032). Predictors of PTS were history of mental health treatment ( p<.001), female gender ( p = .016), fewer years of schooling ( p = .012), and being single/previously married ( p = .004). PTS predicted SI (ρ<.001). Discussion: Health providers should routinely assess Bhutanese refugees’ mental health status for timely further assessment and treatment.

Introduction Children with acute myeloid leukemia (AML) are at risk for serious electrolyte abnormalities. Case report We reported a case of hyperphosphatemia in a child with acute myeloid leukemia who received liposomal amphotericin B (AMBL) for the treatment of an invasive fungal infection. The findings of this case suggest that cumulative dose accumulation due to long term AMBL treatment may result in late-onset hyperphosphatemia. Management and outcome This is the first case report in the literature that of late-onset hyperphosphatemia (day 56) in a patient with low-dose AMBL treatment (3–5 mg/kg/day) and normal renal function. Discussion We highlight the importance of increasing awareness of AMBL related hyperphosphatemia among healthcare providers.

Published: February 2022

Objectives Explantation of both endovascular endovascular aneurysm repair and open aortic grafts is a procedure associated with high peri-operative risk, and the current study sought to determine the outcomes and trends over time in these patients. Methods This study examined data from all patients undergoing explant of an aortic graft (both open and endovascular) between January 2004 and December 2020 at a single centre. Variables analysed included comorbidities, duration to and indication for explantation, type of revascularization, in-hospital complications and mortality, duration of hospital and ICU stay, and out-patient mortality. Results Of 688 open and 1352 EVARs performed, 46 patients underwent 48 explants. Five were open grafts and 43 were endografts, equating to an explant rate of 0.73% of open and 3.18% EVARs. Average time to explant was 70 months, with patients presenting electively having a significantly longer duration to representation than those presenting emergently (51 vs 44 months, p=0.003). Indication for explant was endoleak in 70%, infection in 23%, and occlusion in 6%. Of the endoleaks, 61% of were Type 1, 22% Type II, 11% Type IV, and 6% Type V. On representation, 17 patients (35%) were symptomatic. Overall mortality rate was 8.3%, with a trend for higher mortality in emergent than elective presentations (11.8 vs 6.5%, p=0.55). There was no change in explant rate over time. Conclusions Elective aortic graft explantation is associated with low mortality, despite its complexity and patient comorbidities. Patients presenting with symptoms suffered higher mortality and a longer post-operative course, suggesting that aortic graft explantation should be considered sooner rather than later, rather than persisting with repeated endovascular management.
Complete inguinal bladder hernia causing acute right upper urinary tract obstruction
Authors: Madden-McKee Christopher TJ , Getty Matthew , Thompson Trevor J 
Published: February 2022

Case Summary: An 86-year-old male nursing home resident presented with increasing confusion and was initially treated for catheter-associated urinary tract infection. Computed tomography (CT) scan demonstrated complete inguinal bladder hernia with compression of the right vesico-ureteric junction leading to acute obstructive renal failure. Percutaneous nephrostomy was attempted but was not possible due to patient non-compliance. Patient improved with conservative management. Discussion: Bladder involvement in inguinal hernia is rare with most cases being identified at the time of hernia repair and there is a 17% risk of intra-operative bladder injury. Key risk factors include increasing age, male gender, lower urinary tract symptoms and previous hernia repair. Percutaneous nephrostomy followed by inguinal hernia repair is the treatment of choice for most patients. This case highlights that inguinal bladder hernia can lead to acute upper urinary tract obstruction even when the bladder is catheterised. Level of evidence: IV
Functional outcome following excision of giant cell tumour of the distal radius and reconstruction by autologous non-vascularized osteoarticular fibula graft

Published: February 2022

Purpose Giant cell tumour (GCT) of the bone is a benign but locally aggressive tumour, commonly occurs at the metaphyseal–epiphyseal junction of the distal femur, proximal tibia, and distal radius. For Campanacci grade II and III lesions of the distal radius and in cases of recurrence, we usually carry out wide resection and reconstruction. There are numerous publications on the treatment of GCT of the distal radius. Still, reports on the functional outcome using non-vascularized fibular graft arthroplasty without fusion remain limited. Method We reviewed patients who underwent wide resection and non-vascularized fibular graft arthroplasty from 2007 to May 2014. The assessment was done with Musculoskeletal Tumour Society Score (MSTS), Toronto Extremities Scoring System (TESS) and Disability of the Arm, Shoulder and Hand (DASH) scores. We also reviewed the radiographic results. Results Fifteen patients were recruited, of whom 10 cases used ipsilateral fibular graft and five used contralateral non-vascularized fibular graft. The average duration of follow up was 6 years (3.25–9.92 years). The average grip strength was 48.1% compared to the non-operated hand. The average MSTS score was 78.4 %, TESS score was 84%, and DASH score was 25.2. The average time to radiological union was 12.5 weeks. 64% (29–78%) of the range of movement is preserved compared to the normal side. The complication rate was 20%. Conclusion Fibula autograft arthroplasty is a feasible method of reconstruction after distal radius resection with good functional outcomes.
