A preferred vision for administering elementary schools : a reflective essay

Society will continue to change, and schools will have to meet the challenges of those changes. To meet these challenges, it will be vital to keep abreast of innovations and current trends in education. Motivating teachers to examine and reflect upon their teaching, and empowering them to implement their ideas and programs will be keys to a successful school

Very rapid long-distance sea crossing by a migratory bird

Landbirds undertaking within-continent migrations have the possibility to stop en route, but most long-distance migrants must also undertake large non-stop sea crossings, the length of which can vary greatly. For shorebirds migrating from Iceland to West Africa, the shortest route would involve one of the longest continuous sea crossings while alternative, mostly overland, routes are available. Using geolocators to track the migration of Icelandic whimbrels (Numenius phaeopus), we show that they can complete a round-trip of 11,000 km making two non-stop sea crossings and flying at speeds of up to 24 m s-1; the fastest recorded for shorebirds flying over the ocean. Although wind support could reduce flight energetic costs, whimbrels faced headwinds up to twice their ground speed, indicating that unfavourable and potentially fatal weather conditions are not uncommon. Such apparently high risk migrations might be more common than previously thought, with potential fitness gains outweighing the costs

Role of buccal mucosa graft ureteroplasty in the surgical management of pyeloplasty failure

Objective: Secondary pyeloplasty for recurrent ureteropelvic junction obstruction may be a safe and feasible surgical option for patients. This study aimed to demonstrate outcomes of utilizing a non-transecting buccal mucosa graft ureteroplasty for management of recurrent ureteropelvic junction obstruction after prior failed pyeloplasty. Methods: We performed a retrospective review of our Collaborative of Reconstructive Robotic Ureteral Surgery database for all consecutive patients who underwent buccal mucosa graft ureteroplasty between April 2012 and June 2022 for management of recurrent ureteropelvic junction obstruction after prior failed pyeloplasty. Primary outcome included surgical success which was defined as the absence of flank pain and obstruction on imaging. Results: Overall, ten patients were included in our analysis. The median stricture length was 2.5 (interquartile range IQR 1.8–4.0) cm. Median operative time was 230.5 (IQR 199.5–287.0) min and median estimated blood loss was 50 (IQR 28.8–102.5) mL. At a median follow-up of 10.3 (IQR 6.2–14.8) months, 80% of patients were surgically successful and there were no major (Clavien-Dindo grade>2) complications. Conclusion: Buccal mucosa graft ureteroplasty is a valuable non-transecting surgical option for patients with recurrent UPJO who failed prior pyeloplasty and has comparable outcomes to the literature regarding standard transecting techniques.Lewis Katz School of MedicineUrolog

Symptom appraisal in uncertainty: A theory-driven thematic analysis with survivors of childhood cancer

Objective: Somatic symptoms capture attention, demand interpretation, and promote health behaviors. Symptom appraisal is particularly impactful within uncertain health contexts such as cancer survivorship. Yet, little is known about how individuals make sense of somatic symptoms within uncertain health contexts, nor how this process guides health behaviors. Design: 25 adolescent and young adult survivors of childhood cancer completed semi-structured interviews regarding how they appraise and respond to changing somatic sensations within the uncertain context of survivorship. Main Outcome Measures: Interviews were transcribed verbatim and subjected to a hybrid deductive-inductive thematic analysis, guided by the Cancer Threat Interpretation model. Results: Theme 1 (‘symptoms as signals of bodily threat’) captured that participants commonly interpret everyday sensations as indicating cancer recurrence or new illness. Theme 2 (‘playing detective with bodily signals’) captured the cognitive and behavioral strategies that participants described using to determine whether somatic sensations indicated a health threat. These two themes are qualified by the recognition that post-cancer symptoms are wily and influenced by psychological factors such as anxiety (Theme 3: ‘living with symptom-related uncertainty’). Conclusions: These data highlight the need for novel symptom management approaches that target how somatic sensations are appraised and responded to as signals of bodily threat.<br/

Hemodynamic Effects of Entry and Exit Tear Size in Aortic Dissection Evaluated with In Vitro Magnetic Resonance Imaging and Fluid-Structure Interaction Simulation

Understanding the complex interplay between morphologic and hemodynamic features in aortic dissection is critical for risk stratification and for the development of individualized therapy. This work evaluates the effects of entry and exit tear size on the hemodynamics in type B aortic dissection by comparing fluid-structure interaction (FSI) simulations with in vitro 4D-flow magnetic resonance imaging (MRI). A baseline patient-specific 3D-printed model and two variants with modified tear size (smaller entry tear, smaller exit tear) were embedded into a flow- and pressure-controlled setup to perform MRI as well as 12-point catheter-based pressure measurements. The same models defined the wall and fluid domains for FSI simulations, for which boundary conditions were matched with measured data. Results showed exceptionally well matched complex flow patterns between 4D-flow MRI and FSI simulations. Compared to the baseline model, false lumen flow volume decreased with either a smaller entry tear (-17.8 and -18.5 %, for FSI simulation and 4D-flow MRI, respectively) or smaller exit tear (-16.0 and -17.3 %). True to false lumen pressure difference (initially 11.0 and 7.9 mmHg, for FSI simulation and catheter-based pressure measurements, respectively) increased with a smaller entry tear (28.9 and 14.6 mmHg), and became negative with a smaller exit tear (-20.6 and -13.2 mmHg). This work establishes quantitative and qualitative effects of entry or exit tear size on hemodynamics in aortic dissection, with particularly notable impact observed on FL pressurization. FSI simulations demonstrate acceptable qualitative and quantitative agreement with flow imaging, supporting its deployment in clinical studies.Comment: Judith Zimmermann and Kathrin B\"aumler contributed equall

“You don’t accept he’s completely ok”:A reflexive thematic analysis of parents’ roles in monitoring their child’s health and symptoms after finishing childhood cancer treatment

Objectives/purpose: Childhood cancer survival brings continued mental and physical health challenges both for the child and for the family. In this study, we investigated how parents viewed their roles in their child’s health and symptom monitoring during the survivorship period. Methods: Twenty-one parents of childhood cancer survivors (n = 18 mothers; parent mage = 49.78 years, child mage = 18.50 years; range = 12–25 years), whose children were at least one year off-treatment (m = 3.67 years; SD = 2.25; various diagnoses), completed semi-structured interviews. Interviews were recorded, transcribed, and analyzed using reflexive thematic analysis. Results: Analyses generated three themes which reflect roles that parents may adopt in the context of monitoring symptoms in their childhood cancer survivor. “Vigilant Mama and Papa” (theme 1) described parents who expressed a strong sense of responsibility for protecting their child’s health during survivorship resulting in careful monitoring of their child’s symptoms and health. “Pragmatic Mamas and Papas” (theme 2) described parents who adopted an approach to symptom and health monitoring that emphasized moving past cancer and focusing on the future. Finally, “Encouraging Mamas and Papas” (theme 3) described parents who focused on educating and preparing their child to develop an autonomous approach to health and symptom self-monitoring as they transitioned to survivorship and adulthood. Conclusion: Parents take on varying roles in monitoring their child’s symptoms and health after finishing childhood cancer treatment. Implications for Cancer Survivors: Understanding the ways in which parents continue to be involved in their child’s cancer journey helps researchers develop interventions to support dyadic coping in survivorship.</p
