Quels motifs amènent des professeurs d'université à mettre en place des pratiques pédagogiques non magistrales dans le contexte de l'enseignement à de grands groupes?

Le contexte de l’enseignement supérieur actuel, marqué notamment par la massification et la réduction du budget en éducation, fait en sorte que l’enseignement à de grands groupes d’étudiants est devenu une nécessité, mais aussi un défi chez les professeurs d’université. La taille des groupes influence-t-elle la réussite des étudiants? Plusieurs études, dont celles de Atkinson (2010), Milesi et Gamoran (2006) et Wulff et al. (1987), montrent que, dans ce format d’enseignement, ce n’est pas nécessairement le nombre de participants qui constitue l’élément important, mais la qualité de l’enseignement. En particulier, la recherche de Mulryan-Kyne (2010) affirme que la taille de la classe n’aurait pas d’influence négative sur l’apprentissage si le professeur adopte des stratégies d’enseignement adaptées et les applique dans le contexte approprié. Actuellement, face à un public de plus en plus hétérogène et à l’ère numérique, les professeurs font des efforts pour mettre en place des pratiques pédagogiques non magistrales pour favoriser la réussite et la persévérance chez les étudiants. De ce fait, nous avons cherché à répondre à la question générale de recherche suivante : Quels motifs amènent des professeurs d'université à mettre en place des pratiques pédagogiques non magistrales dans le contexte de l'enseignement à de grands groupes? Et aux cinq questions spécifiques : (1) Quels sont les types d’enseignement que les professeurs d’université ont vécus quand ils étaient étudiant(e)s?, (2) Quels motifs les professeurs d’université invoquent-ils pour expliquer les changements introduits dans leurs pratiques pédagogiques dans l’enseignement à de grands groupes?, (3) Comment les professeurs ont-ils expérimenté ces changements dans leurs pratiques pédagogiques?, (4) Comment est mis en place le changement des pratiques pédagogiques chez les professeurs d’université?, (5) Quelle est la définition de ce qu’est un grand groupe chez les professeurs d’université? Nous avons donc mené une étude qualitative avec des entrevues semi-dirigées auprès de 21 professeurs de deux universités au Québec. À travers l’analyse thématique avec l’aide du support-papier et du logiciel QDA Miner, les résultats de nos analyses ont permis de mettre en évidence, d’une part, le processus qui semble caractériser le changement des pratiques pédagogiques chez les professeurs que nous avons interrogés et, d’autre part, les principaux motifs qui conduisent les professeurs à s’engager dans ce changement.The higher education, in specific the massification and reduction of the education budget, has created a context where teaching large groups of students has become a necessity, creating a challenge for university professors. Does the size of groups influence student success? Several studies, including those of Atkinson (2010); Milesi & Gamoran (2006) and Wulff et al. (1987), show that, in this teaching format, it is not the number of participants that matters, but the quality of teaching. In particular, Mulryan-Kyne's (2010) research points out that class size would not negatively influence learning if the teacher adopts teaching strategies adapted to the appropriate context. Faced with an increasingly heterogeneous audience and in the digital era, professors are making efforts to implement non-traditional practices geared towards student success and perseverance. As a result, this research aims to answer the following questions: What motivates university professors to implement non-lecturing pedagogical practices in the context of teaching large groups? And to the five specific questions: (1) What types of teaching have university professors experienced as students? (2) What reasons do university professors give for changing their teaching practices with large groups? (3) How have university professors experienced these changes in their teaching practices? (4) How are changes in teaching practices implemented by university professors? (5) How do university professors define large student groups? A qualitative study with semi-directed interviews was conducted with 21 professors from two universities in Quebec. Through thematic analysis and using paper support and QDA Miner software, our analysis highlighted, on the one hand, the process that seems to characterize the change in pedagogical practices among the professors we interviewed and, on the other hand, the main motivations that encouraged professors to engage in this change

COMPLETE REPAIR FOR TETRALOGY OF FALLOT IN CHILDREN: SHORT-TERM OUTCOME IN A SINGLE CENTER

Tetralogy of Fallot is a common cyanotic congenital heart disease. Early surgery treatment gives patients a chance to have normal physical and mental health due to preventing complications of cyanosis and even death as a natural history of tetralogy of Fallot. This study aimed to show short-term outcomes (including the time of postoperative hospital stay and 30 days after discharge) of tetralogy of Fallot complete repair at the Department of Pediatric Cardiac Surgery, Cho Ray Hospital. A retrospective study was performed on the data of medical documents of 38 patients, who underwent complete repair for tetralogy of Fallot with full sternotomy and cardiopulmonary bypass from March 2017 to December 2019, following a collection form. The results showed the average age and weight were 33.89±13.02 months and 11.77±2.48 kg. The cardiopulmonary bypass time was 147.74±12.48 mins, the aortic cross-clamp time 104.84±9.73 mins, the mechanical ventilation time 31.14±10.75 hours, the duration of stay in the intensive care unit 58.03±13.56 hours, the postoperative hospital stay time 10.12±1.5 days, and the mortality rate 2.6%. The study concludes that the short-term surgical outcome of complete repair for tetralogy of Fallot in lightweight children is safe and effective with a low mortality rate

The First Probable Case of Hereditary Angioedema in Vietnam

Hereditary angioedema (HAE) is rare disorder due to C1-inhibitor deficiency (C1-INH) that are debilitating and may be life-threatening. HAE is a lack of consensus concerning diagnosis, therapy, and management, particularly in Vietnam. In this case report, we report a 40-year-old male patient with typical clinical symptoms and family history but he showed normal C4 level, and we could not measure C1q and C1-INH level. However, the diagnosis of HAE can be made based on typical clinical symptoms and the favorable prophylactic response to danazol treatment. Based on these findings, we suggest that he has type I HAE, although he showed normal C4 level

Synthesis and redetermination of the crystal structure of salicyl-aldehyde <i>N</i>(4)-morpholino-thio-semi-carbazone.

The structure of the title compound (systematic name: N-{[(2-hy-droxy-phen-yl)methyl-idene]amino}-morpholine-4-carbo-thio-amide), C12H15N3O2S, was prev-iously determined (Koo et al., 1977 ▸) using multiple-film equi-inclination Weissenberg data, but has been redetermined with higher precision to explore its conformation and the hydrogen-bonding patterns and supra-molecular inter-actions. The mol-ecular structure shows intra-molecular O-H⋯N and C-H⋯S inter-actions. The configuration of the C=N bond is E. The mol-ecule is slightly twisted about the central N-N bond. The best planes through the phenyl ring and the morpholino ring make an angle of 43.44 (17)°. In the crystal, the mol-ecules are connected into chains by N-H⋯O and C-H⋯O hydrogen bonds, which combine to generate sheets lying parallel to (002). The most prominent contribution to the surface contacts are H⋯H contacts (51.6%), as concluded from a Hirshfeld surface analysis

Assessment of Drivers of Antimicrobial Usage in Poultry Farms in the Mekong Delta of Vietnam: A Combined Participatory Epidemiology and Q-Sorting Approach

In the Mekong Delta of Vietnam, poultry farmers use high amounts of antimicrobials, but little is known about the drivers that influence this usage. We aimed to identify these drivers using a novel approach that combined participatory epidemiology (PE) and Q-sorting (a methodology that allows the analysis of the subjectivity of individuals facing a common phenomenon). A total of 26 semi-structured collective interviews were conducted with 125 farmers representative of the most common farming systems in the area (chickens, meat ducks, and mobile grazing ducks), as well as with 73 farmers' advisors [veterinarians, veterinary drug shop owners, and government veterinarians/commune animal health workers (CAHWs)] in five districts of Dong Thap province (Mekong Delta). Through these interviews, 46 statements related to the antimicrobials' perceived reliability, costs, and impact on flock health were created. These statements were then investigated on 54 individuals (28 farmers and 26 farmers' advisors) using Q-sorting interviews. Farmers generally indicated a higher propensity for antimicrobial usage (AMU) should their flocks encounter bacterial infections (75.0–78.6%) compared with viral infections (8.3–66.7%). The most trusted sources of advice to farmers were, in decreasing order: government veterinarian/CAHWs, their own knowledge/experience, veterinary drug shop owners, and sales persons from pharmaceutical and feed companies. The highest peak of AMU took place in the early phase of the production cycle. Farmers and their advisors showed considerable heterogeneity of attitudes with regards to AMU, with, respectively, four and three discourses representing their views on AMU. Overall, farmers regarded the cost of AMU cheaper than other disease management practices implemented on their farms. However, they also believed that even though these measures were more expensive, they would also lead to more effective disease prevention. A key recommendation from this finding would be for the veterinary authorities to implement long-term sustainable training programs aiming at reducing farmers' reliance on antimicrobials

PHENOLIC COMPOUNDS FROM CALLISTEMON CITRINUS LEAVES AND STEMS

In the search for bioactive constituents from Vietnamese plants,  the leaves and stems of Callistemon citrinus (Curtis) Skeels were selected for chemical investigation. Phytochemical analysis of plant led to the isolation of eight phenolic compounds including two flavonoids (eucalyptine (1) and 8-demethyleucalyptine (2)), two alcohols (blumenol A (3), n-tetratriacontanol (4)), three benzoic acid derivatives (acid gallic (5), methyl gallate (6) protocatechuic acid (7)), one sterol (b-sitosterol (8)), and along with one sesquiterpene (2,6,10-bisabolatriene (9)). The structures of the natural compounds were determined by spectroscopic evidences including 1D- and 2D-NMR and ESI-MS

Antibiotic use and prescription and its effects on Enterobacteriaceae in the gut in children with mild respiratory infections in Ho Chi Minh City, Vietnam. A prospective observational outpatient study.

BACKGROUND AND OBJECTIVES: Treatment guidelines do not recommend antibiotic use for acute respiratory infections (ARI), except for streptococcal pharyngitis/tonsillitis and pneumonia. However, antibiotics are prescribed frequently for children with ARI, often in absence of evidence for bacterial infection. The objectives of this study were 1) to assess the appropriateness of antibiotic prescriptions for mild ARI in paediatric outpatients in relation to available guidelines and detected pathogens, 2) to assess antibiotic use on presentation using questionnaires and detection in urine 3) to assess the carriage rates and proportions of resistant intestinal Enterobacteriaceae before, during and after consultation. MATERIALS AND METHODS: Patients were prospectively enrolled in Children's Hospital 1, Ho Chi Minh City, Vietnam and diagnoses, prescribed therapy and outcome were recorded on first visit and on follow-up after 7 days. Respiratory bacterial and viral pathogens were detected using molecular assays. Antibiotic use before presentation was assessed using questionnaires and urine HPLC. The impact of antibiotic usage on intestinal Enterobacteriaceae was assessed with semi-quantitative culture on agar with and without antibiotics on presentation and after 7 and 28 days. RESULTS: A total of 563 patients were enrolled between February 2009 and February 2010. Antibiotics were prescribed for all except 2 of 563 patients. The majority were 2nd and 3rd generation oral cephalosporins and amoxicillin with or without clavulanic acid. Respiratory viruses were detected in respiratory specimens of 72.5% of patients. Antibiotic use was considered inappropriate in 90.1% and 67.5%, based on guidelines and detected pathogens, respectively. On presentation parents reported antibiotic use for 22% of patients, 41% of parents did not know and 37% denied antibiotic use. Among these three groups, six commonly used antibiotics were detected with HPLC in patients' urine in 49%, 40% and 14%, respectively. Temporary selection of 3rd generation cephalosporin resistant intestinal Enterobacteriaceae during antibiotic use was observed, with co-selection of resistance to aminoglycosides and fluoroquinolones. CONCLUSIONS: We report overuse and overprescription of antibiotics for uncomplicated ARI with selection of resistant intestinal Enterobacteriaceae, posing a risk for community transmission and persistence in a setting of a highly granular healthcare system and unrestricted access to antibiotics through private pharmacies.

Burden of injury along the development spectrum : associations between the Socio-demographic Index and disability-adjusted life year estimates from the Global Burden of Disease Study 2017

Background The epidemiological transition of non-communicable diseases replacing infectious diseases as the main contributors to disease burden has been well documented in global health literature. Less focus, however, has been given to the relationship between sociodemographic changes and injury. The aim of this study was to examine the association between disability-adjusted life years (DALYs) from injury for 195 countries and territories at different levels along the development spectrum between 1990 and 2017 based on the Global Burden of Disease (GBD) 2017 estimates. Methods Injury mortality was estimated using the GBD mortality database, corrections for garbage coding and CODEm-the cause of death ensemble modelling tool. Morbidity estimation was based on surveys and inpatient and outpatient data sets for 30 cause-of-injury with 47 nature-of-injury categories each. The Socio-demographic Index (SDI) is a composite indicator that includes lagged income per capita, average educational attainment over age 15 years and total fertility rate. Results For many causes of injury, age-standardised DALY rates declined with increasing SDI, although road injury, interpersonal violence and self-harm did not follow this pattern. Particularly for self-harm opposing patterns were observed in regions with similar SDI levels. For road injuries, this effect was less pronounced. Conclusions The overall global pattern is that of declining injury burden with increasing SDI. However, not all injuries follow this pattern, which suggests multiple underlying mechanisms influencing injury DALYs. There is a need for a detailed understanding of these patterns to help to inform national and global efforts to address injury-related health outcomes across the development spectrum.Peer reviewe

Global, regional, and national incidence, prevalence, and years lived with disability for 354 diseases and injuries for 195 countries and territories, 1990-2017: a systematic analysis for the Global Burden of Disease Study 2017.

The Global Burden of Diseases, Injuries and Risk Factors 2017 includes a comprehensive assessment of incidence, prevalence, and years lived with disability (YLDs) for 354 causes in 195 countries and territories from 1990 to 2017. Previous GBD studies have shown how the decline of mortality rates from 1990 to 2016 has led to an increase in life expectancy, an ageing global population, and an expansion of the non-fatal burden of disease and injury. These studies have also shown how a substantial portion of the world's population experiences non-fatal health loss with considerable heterogeneity among different causes, locations, ages, and sexes. Ongoing objectives of the GBD study include increasing the level of estimation detail, improving analytical strategies, and increasing the amount of high-quality data. METHODS: We estimated incidence and prevalence for 354 diseases and injuries and 3484 sequelae. We used an updated and extensive body of literature studies, survey data, surveillance data, inpatient admission records, outpatient visit records, and health insurance claims, and additionally used results from cause of death models to inform estimates using a total of 68 781 data sources. Newly available clinical data from India, Iran, Japan, Jordan, Nepal, China, Brazil, Norway, and Italy were incorporated, as well as updated claims data from the USA and new claims data from Taiwan (province of China) and Singapore. We used DisMod-MR 2.1, a Bayesian meta-regression tool, as the main method of estimation, ensuring consistency between rates of incidence, prevalence, remission, and cause of death for each condition. YLDs were estimated as the product of a prevalence estimate and a disability weight for health states of each mutually exclusive sequela, adjusted for comorbidity. We updated the Socio-demographic Index (SDI), a summary development indicator of income per capita, years of schooling, and total fertility rate. Additionally, we calculated differences between male and female YLDs to identify divergent trends across sexes. GBD 2017 complies with the Guidelines for Accurate and Transparent Health Estimates Reporting
