Prácticas docentes para creatividad en la universidad: estudio en Portugal y Brasil

Creativity is nowadays seen as an essential feature in higher education. Nevertheless, there is a discrepancy between the need for creativity and what higher education classrooms provide. This study assessed the perceptions of 1599 higher education students from two countries (1059 Brazilian and 540 Portuguese students), from two academic domains (Sciences and Technologies – Sc&T; Social Sciences, Arts, and Humanities – SScA&H), about the presence of creativity in their teachers’ instruction and evaluation practices. The study’s findings evidence interactive effects between the variables country and academic domain for most of the assessed factors: encouragement of new ideas, climate for the expression of ideas, and interest in students’ learning. Brazilian Sc&T students presented more negative perceptions of their classroom environments when compared to SScA&H students; Portuguese students showed opposite patterns of results. Some hypothetical explanations are discussed and future directions for research are presented.Criatividade é atualmente tomada como aspecto essencial na Educação Superior.

Odontogenic facial swelling of unknown origin

BACKGROUND: Current radiography techniques have limitations in detecting subtle odontogenic anomalies or defects that can lead to dentoalveolar and facial infections. This report examines the application of micro-CT imaging on two extracted teeth to enable detailed visualization of subtle odontogenic defects that had given rise to facial swellings. METHODS: Two extracted non-carious mandibular left primary canine teeth (73) associated with odontogenic infections were selected from healthy patients, and an intact contralateral tooth (83) from one of the patients was used as a control. All three teeth were subjected to the three-dimensional micro-CT imaging at a resolution of 20 μm. RESULTS: Tooth 73 from the first case displayed dentine pores (channels) that established communication between the pulp chamber and the exposed dentine surface. In comparison, tooth 73 from the second case had a major longitudinal crack extending from the external enamel surface into the pulp chamber. The control tooth did not display any anomalies or major cracks. CONCLUSIONS: The scope of micro-CT imaging can be extended from current in vitro applications to establish post-extraction diagnosis of subtle odontogenic defects, in a manner similar to confirming histopathological diagnoses in extracted teeth. Ongoing technological advancements hold the promise for more widespread translatory applications.S Ranjitkar, W Cheung, R Yong, J Deverell, M Packianathan, C Hal

Significant reductions in tertiary hospital encounters and less travel for families after implementation of Paediatric Care Coordination in Australia 11 Medical and Health Sciences 1117 Public Health and Health Services

Background: Over a third of Australian children have long-term health conditions, often involving multiple organ systems and resulting in complex health care needs. Our healthcare system struggles to meet their needs because of sectoral fragmentation and episodic models of care. Children with medical complexity (CMC) currently rely on tertiary paediatric hospitals for most of their healthcare, but this is not sustainable. We evaluated the impacts of Care Coordination on tertiary hospital service use and family outcomes. Methods: A pre- and post-implementation cohort evaluation of the Care Coordination service at a tertiary paediatric hospital network, was undertaken. From July 2015 CMC enrolled in the service had access to a Care Coordinator, shared-care plans, linkage with local general practitioners (GPs), and access to a 24-h Hotline from August 2016. CMC were those with ≥4 emergency department (ED) presentations, hospital stays of ≥14 days, or ≥ 10 outpatient appointments in 12 months. Medically fragile infants at risk of frequent future hospital utilisation, and children with medical problems complicated by difficult family psychosocial circumstances were also included. Care Coordinators collected outcomes for each enrolled child. Administrative data on hospital encounters 6 months pre- and post-enrolment were analysed for children aged > 6 months. Results: An estimated 557 hospital encounters, were prevented in the 6 months after enrolment, for 534 children aged > 6 months. ED presentations decreased by 40% (Chi2 = 37.95; P < 0.0001) and day-only admissions by 42% (Chi2 = 7.54; P < 0.01). Overnight admissions decreased by 9% but this was not significant. An estimated Au4.9 million was saved over 2 years due to prevented hospital encounters. Shared-care plans were developed for 83.5%. Of 84 children who had no regular GP, 58 (69%) were linked with one. Fifty-five (10%) of families were linked to the 24-h Hotline to enable remote access to support and advice. Over 50,000 km of family travel and 370 school absences was prevented. Conclusions: The Care Coordination service has clear benefits for the tertiary paediatric hospital network and for families. Ongoing evaluation is essential for continuous improvement and to support adjustments to the model according to the local context

Palladium-mediated organic synthesis using porous polymer monolith formed in situ as a continuous catalyst support structure for application in microfluidic devices

The development and advantages of in situ synthesis of organic polymer monolith supports for metal pre-catalysts in narrow bore fused silica capillary microreactors are described. Catalyst immobilisation involves the covalent attachment of ligand binding sites to the porous polymer monolith, followed by coordination to metal centres. Flow-through microreactors using poly(chloromethylstyrene-co-divinylbenzene) monolith in capillaries of internal diameter 250 micrometers were used successfully for Suzuki– Miyaura and Sonogashira reactions, utilising both 1,10-phenanthroline and imidazole/carbene binding to palladium and with very low palladium leaching, illustrating the potential of flow-through technology at the microscale level using organic monolith support for transition metal catalysed reactions. Polymer monoliths, present as a continuous phase filling capillaries and bonded to the internal surface, are promising new materials for solid supported catalysis in microreactors. The performance of the flow-through microreactors included quantitative yields for the conversion of iodobenzene in the Suzuki–Miyaura reaction, and quantitative yields for Sonagashira coupling of p-iodoacetophenone with phenylacetylene

Supported palladium catalysis using a heteroleptic 2-methylthiomethylpyridine–N,S–donor motif for Mizoroki–Heck and Suzuki–Miyaura coupling, including continuous organic monolith in capillary microscale flow-through mode

Flow-through catalysis utilising (2-methylthiomethyl-pyridine)palladium(II) chloride species covalently attached to a macroporous continuous organic polymer monolith synthesised within fused silica capillaries of internal diameter 250 microns is described, together with related studies of ground bulk monolith compared with supported catalysis on Merrifield and Wang beads and homogeneous catalysis under identical conditions to bulk supported catalysis. The monolith substrate, poly(chloromethylstyrene-co-divinylbenzene), has a backbone directly related to Merrifield and Wang resins. The homogeneous precatalyst PdCl2(L2)(L2 = 4-(4-benzyloxyphenyl)-2-methylthiomethyl-pyridine) contains the benzyloxyphenyl group on its periphery as a model for the spacer between the ‘PdCl2(N~S)’ centre and the polymer substituent of the resins and monolith. Suzuki–Miyaura and Mizoroki–Heck catalysis exhibit anticipated trends in reactivity with variation of aryl halide reagents for each system, and show that supported catalysis on beads and monolith gives higher yields than for homogeneous catalysis. The synthesis of 2-methylthiomethylpyridines is presented, together with crystal structures of 4-bromo-2-bromomethylpyridine hydrobromide, 4-(4-hydroxyphenyl)-2-methylthiomethylpyridine (L1), PdCl2(L1) and PdCl2(L2). Hydrogen bonding occurs in 4-bromo-2-bromomethylpyridine hydrobromide as N–H/Br interactions, in 4-(4-hydroxyphenyl)-2-methylthiomethylpyridine as O–H/N to form chains, and in PdCl2(L1) as O–H/Cl interactions leading to adjacent pi-stacked chains oriented in an antiparallel fashion
