Learning through role-playing games: an approach for active learning and teaching

This study evaluates the use of role-playing games (RPGs) as a methodological approach for teaching cellular biology, assessing student satisfaction, learning outcomes, and retention of acquired knowledge. First-year undergraduate medical students at two Brazilian public universities attended either an RPG-based class (RPG group) or a lecture (lecture-based group) on topics related to cellular biology. Pre- and post-RPG-based class questionnaires were compared to scores in regular exams and in an unannounced test one year later to assess students' attitudes and learning. From the 230 students that attended the RPG classes, 78.4% responded that the RPG-based classes were an effective tool for learning; 55.4% thought that such classes were better than lectures but did not replace them; and 81% responded that they would use this method. The lecture-based group achieved a higher grade in 1 of 14 regular exam questions. In the medium-term evaluation (one year later), the RPG group scored higher in 2 of 12 questions. RPG classes are thus quantitatively as effective as formal lectures, are well accepted by students, and may serve as educational tools, giving students the chance to learn actively and potentially retain the acquired knowledge more efficiently.

Teaching project: a low-cost swine model for chest tube insertion training

Objective: to describe and evaluate the acceptance of a low-cost chest tube insertion porcine model in a medical education project in the southwest of Paraná, Brazil. Methods: we developed a low-cost and low technology porcine model for teaching chest tube insertion and used it in a teaching project. Medical trainees - students and residents - received theoretical instructions about the procedure and performed thoracic drainage in this porcine model. After performing the procedure, the participants filled a feedback questionnaire about the proposed experimental model. This study presents the model and analyzes the questionnaire responses. Results: seventy-nine medical trainees used and evaluated the model. The anatomical correlation between the porcine model and human anatomy was considered high and averaged 8.1±1.0 among trainees. All study participants approved the low-cost porcine model for chest tube insertion. Conclusion: the presented low-cost porcine model for chest tube insertion training was feasible and had good acceptability among trainees. This model has potential use as a teaching tool in medical education.

Prevalência da síndrome metabólica em portadoras da síndrome dos ovários policísticos

OBJETIVO: avaliar a prevalência da síndrome metabólica nas portadoras da síndrome dos ovários policísticos (SOP). MÉTODOS: foram avaliadas 46 mulheres com SOP, segundo os critérios de Rotterdam (2003), e 44 mulheres saudáveis, com ciclos menstruais regulares, ausência de hiperandrogenismo clínico ou laboratorial e de microcistos ovarianos ao ultra-som pélvico (grupo controle). Para o diagnóstico da síndrome metabólica foram considerados os critérios do National Cholesterol Education Program (NCEP, 2002) e da International Diabetes Federation (IDF, 2005). RESULTADOS: a prevalência da síndrome metabólica foi de 30,4% nas portadoras da SOP e de 6,8% no grupo controle, segundo critérios do NCEP, e de 32,6 e 9,1% nas pacientes com SOP e controles, respectivamente, segundo os critérios da IDF. A diferença entre estas proporções foi estatisticamente significante (p=0,004), independente do critério utilizado, do IMC e da idade. Ao analisarmos cada componente individual da síndrome metabólica, observamos que a anormalidade metabólica mais freqüente nas portadoras da SOP foi o HDL colesterol abaixo de 50 mg/dL, ocorrendo em 52,2% dos casos. As prevalências da glicemia de jejum superior a 110 mg/dL (4,3%), circunferência abdominal >88 cm (47,8%), e pressão arterial >130/85 mmHg (28,2%) foram significativamente maior nas portadoras da SOP. CONCLUSÕES: a síndrome metabólica é significativamente mais freqüente nas pacientes com SOP que na população geral, independente da idade e do IMC, o que pode significar um maior risco cardiovascular nestas pacientes.

Internal quality control indicators of cervical cytopathology exams performed in laboratories monitored by the External Quality Control Laboratory

PURPOSE: To evaluate the impact of continued education provided by an external quality control laboratory on the indicators of internal quality control of cytopathology exams.METHODS: The internal quality assurance indicators for cytopathology exams from 12 laboratories monitored by the External Quality Control Laboratory were evaluated. Overall, 185,194 exams were included, 98,133 of which referred to the period preceding implementation of a continued education program, while 87,061 referred to the period following this intervention. Data were obtained from the Cervical Cancer Database of the Brazilian National Health Service.RESULTS: Following implementation of the continued education program, the positivity index (PI) remained within recommended limits in four laboratories. In another four laboratories, the PI progressed from below the limits to within the recommended standards. In one laboratory, the PI remained low, in two laboratories, it remained very low, and in one, it increased from very low to low. The percentage of exams compatible with a high-grade squamous intraepithelial lesion (HSIL) remained within the recommended limits in five laboratories, while in three laboratories it progressed from below the recommended levels to >0.4% of the total number of satisfactory exams, and in four laboratories it remained below the standard limit. Both the percentage of atypical squamous cells of undetermined significance (ASC-US) in relation to abnormal exams, and the ratio between ASC-US and intraepithelial lesions remained within recommended levels in all the laboratories investigated.CONCLUSION: An improvement was found in the indicators represented by the positivity index and the percentage of exams compatible with a high-grade squamous intraepithelial lesion, showing that the role played by the external quality control laboratory in providing continued education contributed towards improving laboratory staff skills in detecting cervical cancer precursor lesions.

Papel protetor do alelo G do polimorfismo no gene Interleucina 10 (-1082G/A) contra o desenvolvimento de pré-eclâmpsia

OBJETIVOS:Identificar a frequência do polimorfismo no gene IL-10, rs1800896 (-1082 A/G), em mulheres com pré-eclâmpsia (PE) e em mulheres do grupo controle e associar a presença deste polimorfismo com a proteção contra o desenvolvimento da PE.MÉTODOS:Estudo do tipo caso-controle, no qual foram selecionadas 54 mulheres com PE, classificadas de acordo com os critérios da National High Blood Pressure Education Program e 172 mulheres do grupo controle, com pelo menos duas gestações saudáveis. O polimorfismo proposto foi estudado utilizando-se a técnica de reação em cadeia da polimerase em tempo real (qPCR), com sondas de hidrólise. A análise estatística foi realizada utilizando-se o teste de associação do χ2. Odds ratio e seu intervalo de confiança de 95% foram usados para medir a força de associação entre o polimorfismo estudado e o desenvolvimento da PE.RESULTADOS:Foi observado aumento significativo da frequência do genótipo AG entre mulheres do grupo controle (85 versus 15% nas mulheres com PE). O alelo G é significativamente mais frequente entre as mulheres do grupo controle do que nas com PE (Teste χ2; p=0,01). Oodds ratio para as portadoras do alelo G foi de 2, 13, indicando que apresentam menor risco de desenvolver PE do que as não portadoras.CONCLUSÕES:Sugere-se associação entre a presença do alelo G do polimorfismo no geneIL-10, rs1800896 (-1082 A/G), e a proteção contra o desenvolvimento da PE. Mais estudos sobre a contribuição dessas variações e os mecanismos pelos quais afetam o risco de desenvolver PE ainda necessitam de ser realizadas.

Fatores preditivos para a ocorrência de pólipos endometriais em mulheres na pós-menopausa

OBJETIVO:Avaliar os fatores clínicos preditivos para o desenvolvimento dos pólipos endometriais em mulheres na pós-menopausa.MÉTODOS:Estudo de coorte observacional com mulheres na pós-menopausa, que haviam sido atendidas em hospital público universitário. Dados clínicos, antropométricos, laboratoriais e ultrassonográficos de 132 pacientes com diagnóstico anatomopatológico de pólipo endometrial e de 264 mulheres sem alterações endometriais (controle) foram comparados para avaliar os fatores preditivos do pólipo endometrial. Foram incluídas no estudo mulheres com amenorreia ≥12 meses e idade ≥45 anos, em uma proporção de 1 caso para 2 controles. Para a análise estatística, foram empregados os testes t de Student, χ2 e regressão logística — odds ratio (OR).RESULTADOS:As pacientes com pólipo endometrial apresentaram idade mais avançada e maior tempo de menopausa quando comparadas ao controle (p<0,0001). A porcentagem de mulheres obesas com pólipo (72,0%) foi superior à do Grupo Controle (39%; p<0,0001). A medida da circunferência da cintura foi superior entre as pacientes com pólipo (p=0,0001). Observou-se uma incidência de diabetes, hipertensão e dislipidemias mais elevada nas pacientes com pólipo endometrial (p<0,0001). De acordo com os critérios do US National Cholesterol Education Program/Adult Treatment Panel III (NCEP/ATP III), 48,5% das mulheres com pólipo e 33,3% do Grupo Controle foram classificadas como portadoras de síndrome metabólica (p=0,004). Em relação ao Grupo Controle, apresentaram maior chance de desenvolvimento de pólipo endometrial as pacientes com: IMC≥25 kg/m2 (OR=4,6; IC95% 2,1–10,0); glicose ≥100 mg/dL (OR=2,8; IC95% 1,3–5,9); dislipidemia (OR=7,0; IC95% 3,7–13,3); diabetes (OR=2,5; IC95% 1,0–6,3) e síndrome metabólica (OR=2,7; IC95% 1,1–6,4).CONCLUSÃO:Em mulheres na pós-menopausa, obesidade, dislipidemia, hiperglicemia e presença de síndrome metabólica foram fatores preditivos para o desenvolvimento de pólipo endometrial.

Polymorphism in the lymphotoxin-alpha gene, position +252 (rs909253), is not associated with preeclampsia development in Brazilian women

PURPOSE: To investigate the frequencies of polymorphic allele and genotypes for the LT-α gene, position +252 (rs909253), in Brazilian women with preeclampsia.METHODS: This is a case-control study, in which 30 women with preeclampsia, classified according to the criteria of the National High Blood Pressure Education Program, and 115 women in the control group, with at least two healthy pregnancies, were selected. Peripheral blood was collected, and DNA was extracted, followed by genotyping, using specific primers and restriction analysis. The genotypes obtained were AA, AG and GG. Statistical analysis was performed using the χ2association test. The Hardy-Weinberg Equilibrium was tested using the Haploview Program.RESULTS: The results showed no association between genotypes and preeclampsia development (χ2=2.0; p=0.4). When the AG and GG genotypes were grouped according to allele G presence or absence (genotype AA), the data showed that the presence of allele G was not significantly different between cases (women with preeclampsia) and controls (χ2=0.0; p=1.0). The LT-α gene polymorphism, position +252 (rs909253), seems not to be an important candidate for the development of preeclampsia. Other inflammatory genes should be researched, and studies involving gene-environment interactions should be performed, in order to reach a better understanding of the etiology of the preeclampsia.

Mapping cancer, cardiovascular and malaria research in Brazil

This paper presents performance indicators for the Brazilian cancer, cardiovascular and malaria research areas from 1981 to 1995. The data show an increasing number of papers since 1981 and author numbers indicate a continuous growth of the scientific community and suggest an expected impact of scientific activity on biomedical education. The data also characterize cardiovascular research as a well-established area and cancer research as a faster growing consolidating field. The 1989-1994 share of Brazilian articles among world publications shows a growing trend for the cancer (1.61) and cardiovascular (1.59) areas, and a decrease for the malaria area (0.89). The burden of the three diseases on society is contrasted by the small number of consolidated Brazilian research groups, and a questionable balance of thematic activity, especially with regard to malaria. Brazilian periodicals play an important role in increasing the international visibility of science produced in the country. Cancer and cardiovascular research is strongly concentrated in the Southeastern and in Southern regions of Brazil, especially in São Paulo (at least one address from São Paulo in 64.5% of the 962 cancer articles and in 66.9% of the 2250 cardiovascular articles, the second state being Rio de Janeiro with at least one address in 14.1 and 11% of those articles, respectively). Malaria research (468 articles) is more evenly distributed across the country, following the pattern of the endemic distribution of the disease. Surveying these national indicator trends can be useful to establish policies in the decision process about health sciences, medical education and public health.

Psykoosipotilaille tarkoitetun sähköisen potilasopetusmentelmän levitys ja mielenterveystyön ammattilaisten kokemuksia käytöstä

Tämän laadullisen tutkimuksen tarkoituksena oli kuvata psykoosipotilaille tarkoitetun sähköisen potilasopetusmentelmän (MieliNet) levitystä sekä sosiaali- ja terveydenhuollon psykiatristen toimintayksiköiden mielenterveystyön ammattilaisten kokemuksia sähköisen potilasopetusmenetelmän käytöstä. Tutkimuksen tavoitteena on saatavan tiedon avulla kehittää edelleen MieliNet-ohjelman hyödynnettävyyttä psykiatrisessa hoitotyössä. Tutkimusaineisto kerättiin kolmessa vaiheessa. Ensimmäisessä vaiheessa selvitettiin sosiaali- ja terveydenhuollon psykiatristen toimintayksiköiden (n = 125) kiinnostusta tutustua sähköiseen potilasopetukseen. Potilasopetuksesta kiinnostuneiden organisaatioiden (n = 16) taustatiedot kuvattiin sekä selvitettiin mielenterveystyön ammattilaisten (n = 41) halukkutta tutustua MieliNet-sivustoon ja osallistua sähköisen potilasopetuksen verkkokurssille. Toisessa ja kolmannessa vaiheessa aineisto kerättiin sähköiselle moodle-alustalle sähköisen potilasopetusmenetelmän koekäyttäjiltä (n=7). Aineisto analysoitiin induktiivista ja deduktiivista sisällön analyysiä käyttäen. Tutkimustulosten mukaan sähköisestä potilasopetusmenetelmästä kiinnostuneiden organisaatioiden osuus oli 4% niistä organisaatioista, joille tiedon levitys tapahtui. Sähköisen potilasopetusmenetelmän koekäyttäjistä valtaosa työskenteli erikoissairaanhoidossa toimivissa aikuispsykiatrian avohoidon yksiköissä. Sähköisen potilasopetusmenetelmän käytön vahvuuksina koettiin potilasopetuksen tehostuminen, omahoitajasuhteen kehittyminen ja potilaiden lisääntynyt hoitoon sitoutuminen. Heikkouksina koettiin ongelmat sähköisen potilasopetusohjelman käytössä ja ennakkoluulot sähköisen potilasopetusohjelman käytöstä sekä potilaiden psyykkisen voinnin heikentyminen. Mahdollisuuksina koettiin potilasopetuksen tehostuminen ja potilasopetusohjelman uudet käyttömahdollisuudet. Uhkina koettiin sähköisen potilasopetusmenetelmän riittämätön arvostus sekä ongelmat ja ennakkoluulot potilasopetusohjelman käytössä. Potilaiden yksilöllisyys huomioitiin hyvin potilasopetustilanteissa. Sähköinen potilasopetusmenetelmä synnytti keskustelua potilaille tärkeistä asioista. Potilasopetustilanteiden sujuminen, potilaiden asenne ja oma osaaminen aiheuttivat huolta. Potilasopetustilanteisiin valmistautumiseen halutaan jatkossa kiinnittää enemmän huomiota.

Prevalence of metabolic syndrome and its associated factors in renal transplant recipients

INTRODUCTION: The population of patients undergoing renal transplantation is considered at highrisk for developing obesity and changes in lipid and glucose metabolism, due to the use of immunosuppressive drugs and increased food freedom in the post-transplant period. OBJECTIVE: This study was designed to assess the prevalence of metabolic syndrome in renal transplant recipients and to identify factors associated with its occurrence. METHODS: A cross-sectional study was performed in renal transplant patients, with more than six months of follow-up. The metabolic syndrome was diagnosed according to the criteria of the National Cholesterol Education Program Adult Treatment Panel III. RESULTS: Among the 87 pa- tients enrolled, 39 (44.8%) presented the phenotype of metabolic syndrome. The mean age of the patients was 43.5 ± 12.1 years-old, with a predominance of male (69.0%) and white (66.7%). The mean and median times of post transplant follow-up were 64.2 ± 49.4 and 56 months, respectively. All the 12 patients who developed post-transplant diabetes mellitus also met the criteria for metabolic syndrome, which compromised the inclusion of this variable in the logistic regression. In the univariate analysis, patients with metabolic syndrome had higher mean age (p = 0.008), higher median blood level of cyclosporine (p = 0.021), higher prevalence of history of coronary disease (p = 0.023), and they were more frequent users of beta (p = 0.011) and calcium- channel blockers (p = 0.039). In the multivariate analysis, age (HR = 1.06; 95% CI=1.01-1.11, p=0.006) and use of beta-blockers (HR = 4.02; 95% CI = 1.41 - 11.4, p = 0.009) were asso- ciated with increased risk of metabolic syndrome. CONCLUSION: Metabolic syndrome was highly prevalent in the population of renal trans- plant recipients studied, and it was associated with older age, use of beta-blockers, and post-transplant diabetes mellitus.

Examining experiences that develop responsivity in practitioners

This thesis has been produced to meet the requirements of Brock University's Masters of Education program. It is the result of many peoples' reflections on and beliefs about the act of teaching in today's world. This manuscript is intended to provide the reader with an engaged interpretation of the dynamic field of teaching. In recognizing the ever-changing demands of the profession, this paper serves to provide the reader with a gathering of strategies or paradigm of action which an educator may employ to respond to the demands of his/her complex vocation. This gathering of strategies represents the phenomenon I have examined throughout this study: responsivity. What is it? Is it important for a practitioner to develop? If so, how can it be developed? In no way is this an "answer book" for teachers to adhere to. It is a collection of thoughts and ideas from an array of "insiders" who have experienced the phenomenon of responsivity. It will not provide the reader with immediate answers. What it will offer the reader is a deeper understanding of the related issues and concerns surrounding responsivity.

Facilitating self-directed learning: the nurse educators' perspective

The concept of self-directed learning was examined from the nurse educators' perspective. One structured interview, lasting between one and one-and-a half hours, was conducted with each of 14 nurse educators in two community college continuing education programs in nursing. One community college program encourages selfdirected learning; the other encourages self-study and active participation in the teaching/learning process. All 14 interviews were tape-recorded and transcribed verbatim. Verbatim transcripts were analyzed for themes, patterns, and relationships utilizing analyst-constructed typologies. six prerequisites or necessary conditions for facilitating self-directed learning in a community college continuing education program in nursing were identified. ~he crucial issue in facilitating self-directed learning was found to be the issue of teacher-control.

Creating a global consciousness throught the driver model of curriculum development

The purpose of this study was to investigate the effect a human link through the One World Youth Project has on a global education program, if a human connection through the program enhances a student's ability to develop a critical consciousness of global issues, and the etTectiveness of thc constructivist-based Driver Model of Curriculum Development, which served as the curriculum model in this study. An action based research cycle was chosen as this study's research methodology and incorporated 5 qualitative data collection instruments: a) interviews and questionnaires, b) artifacts, c) teacher journal, d) critical friend's observation forms, and e) my critical friend's postobservation interviews. The data were conected from 4 student participants and my critical friend during all stages of the action research cycle. The results of this study provide educators with data on the impact of human connections in a global education program, the effects these connections have on students, and the effectiveness of the Driver Model of Curriculum Development. This study also provides practical activities and strategies that could be used by educators to develop their own global education programs. The United Nations drafted the Millennium Development Goals in an effort to improve the lives of billions of people across the globe. The eight goals were developed with the support of all member nations since all human beings are global citizens who have a responsibility to make the world a better place. Students need to develop a critical consciousness of global issues so that they can work with others to eliminate them. Students who are taught to restate the opinions of others win not be prepared to inherit a world full of challenges that will require new innovative ideas to foster positive change.

An Exploration Into Doctoral Students' Sense of Community and its Influence on the Formation of Informal Mentoring Relationships

This exploratory mixed method research project was designed to investigate an area of doctoral education that has received little attention in the past. This research focused specifically on the non-intellectual, hoped-for by-products of doctoral education; the dynamic processes of developing and maintaining both a sense of community and informal mentoring relationships. The design of the study captured the experiences of doctoral students and alumni at various time periods in the doctoral program. Participants represented a diverse group of students with differences in professional and academic backgrounds and life stages. A pilot study for this research suggested that the presence of a sense of community and informal mentoring may provide the necessary relationships to support this diversity. The primary question at the forefront of this study was: Do doctoral students feel connected to one another? Five subquestions were developed to address this research topic: Does a sense of community already exist and flourish in doctoral education? Are the programs and resources of the doctoral program organized to nurture the creation and maintenance of a sense of community? Is a sense of community a foundational element in the formation of naturally occurring relationships among doctoral students? What educational and socio-emotional benefits are associated with informal mentoring relationships during the doctoral experience? and Do doctoral students perceive a change in their development as stewards of their discipline over time? The principal methods used to investigate these research questions combined both quantitative and qualitative techniques in a concurrent time sequence. The quantitative portion of the study involved a questionnaire, while the qualitative portion involved two approaches; face-to-face interviews and an open-ended question at the end of the questionnaire. Findings from the study indicated that the presence of both sense of community and informal mentoring enhance the overall quality of doctoral education. Program elements that enhanced or hindered connection between students were identified. Both the dynamics and the emotional, social, and academic benefits of informal mentoring were elucidated. Over time participants perceived changes in their development of the qualities assqciated with stewardship. This study brought the "hoped-for by-products" associated with doctoral education from the background shadows to an illuminated position at the forefront of inquiry.

Mental Health and Becoming a Teacher: A Narrative on the Experiences and Identities of Teacher Candidates

This study used narrative inquiry to shed light on the identity development of teacher candidates who experienced mental health issues during teacher education programs. The study sought to examine (a) stories that teacher candidates tell about being in a teacher education program while experiencing mental health issues; (b) identity development of teachers who have experienced mental health issues; and (c) how narratives of teacher candidates and beginning teachers challenge stereotyping and stigmatization. Through discussion and letter correspondence, the participants and I shared stories that represented our lived experiences. The study explored our stories using the 3 commonplaces of temporality, sociality, and place from a theoretical framework of narrative inquiry. Four themes emerged from the data analysis: the stigmatization of mental health issues; dealing with conflict; the need for a safe and supportive environment; and the complexity of mental health issues. This study contributes to the literature by exploring the lived experiences of teacher candidates and beginning teachers with mental health issues. The narratives inform teacher education programs, the teaching profession, and the mental health field.
