Pratique dentaire en milieu rural : perspectives des étudiants en médecine dentaire du Québec

Introduction: La répartition de la main-d'oeuvre dentaire à travers le Canada est fortement balancée en faveur des zones urbaines, une situation qui favorise les disparités dans l'accès aux soins de santé buccodentaire. En engageant des professionnels de la santé buccodentaire dans la pratique dentaire en milieu rural, il faut d’abord comprendre leurs opinions personnelles et professionnelles, ainsi que les obstacles et les facteurs motivant leur choix de pratique. Cependant, il existe un manque des connaissances sur la perception des étudiants de soins de santé buccodentaire à l'égard de la pratique rurale. Par conséquent, nous avons voulu vérifier comment les étudiantes en médecine dentaire perçoivent la pratique dentaire en milieu rural. Méthodes: Nous avons effectué une recherche qualitative dans deux grandes facultés de médecine dentaire au Québec. Un échantillonnage intentionnel et la technique boule de neige ont été utilisé pour recruter des étudiants finissants et des résidents en médecine dentaire en tant que participants à l'étude. Des enregistrements sonores des entrevues, d’une durée de 60 à 90 minutes, semi-structurées et face à face ont été colligés jusqu’à atteinte de la saturation. Nous avons procédé à une analyse thématique pour dégager les enjeux. Cela a inclus un compte-rendu des entrevues, l’encodage des transcriptions, la présentation des données et leur interprétation. Résultats: Dix-sept entretiens (10 F et 7 M, âge: 22 à 39) ont été réalisées. Cinq grands thèmes ont émergé des entrevues: niveau des connaissances sur les inégalités de la santé buccodentaire en milieu rural, image de la ruralité, image de la pratique dentaire en milieu rural, obstacles perçus et facteurs mobilisateurs. Les étudiants ont exprimé que l'éducation dentaire, les avantages financiers, le professionnalisme, le soutien professionnel, et les médias sociaux peuvent influencer positivement leur intérêt à l’égard de la pratique dentaire en milieu rural. Conclusion : Les résultats de cette étude soutiennent la mise en place de stratégies connues pour augmenter la connaissance et la motivation des étudiants en médecine dentaire pour choisir leur profession dans une région rurale. Les acteurs des politiques éducatives ont un rôle essentiel dans la promotion de ces politiques et stratégies facilitantes.

Hypotensive effects of hawthorn for patients with diabetes taking prescription drugs: a randomised controlled trial

Background Hawthorn (Crataegus laevigata) leaves, flowers and berries are used by herbal practitioners in the UK to treat hypertension in conjunction with prescribed drugs. Small-scale human studies support this approach. Aim To investigate the effects of hawthorn for hypertension in patients with type 2 diabetes taking prescribed drugs. Design of study Randomised controlled trial. Setting General practices in Reading, UK. Method Patients with type 2 diabetes (n = 79) were randomised to daily 1200 mg hawthorn extract (n = 39) or placebo (n = 40) for 16 weeks. At baseline and outcome a wellbeing questionnaire was completed and blood pressure and fasting blood samples taken. A food frequency questionnaire estimated nutrient intake. Results Hypotensive drugs were used by 71% of the study population with a mean intake of 4.4 hypoglycaemic and/or hypotensive drugs. Fat intake was lower and sugar intake higher than recommendations, and low micronutrient intake was prevalent. There was a significant group difference in mean diastolic blood pressure reductions (P = 0.035): the hawthorn group showed greater reductions (baseline: 85.6 mmHg, 95% confidence interval [Cl] = 83.3 to 87.8; outcome: 83.0 mmHg, 95% Cl = 80.5 to 85.7) than the placebo group (baseline: 84.5 mmHg, 95% Cl = 82 to 87; outcome: 85.0 mmHg, 95% Cl = 82.2 to 87.8). There was no group difference in systolic blood pressure reduction from baseline (3.6 and 0.8 mmHg for hawthorn and placebo groups, respectively; P = 0.329). Although mean fat intake met current recommendations, mean sugar intake was higher and there were indications of potential multiple micronutrient deficiencies. No herb-drug interaction was found and minor health complaints were reduced from baseline in both groups. Conclusions This is the first randomised controlled trial to demonstrate a hypotensive effect of hawthorn in patients with diabetes taking medication.

Training pharmacists to deliver a complex information technology intervention (PINCER) using the principles of educational outreach and root cause analysis

Objective: To describe the training undertaken by pharmacists employed in a pharmacist-led information technology-based intervention study to reduce medication errors in primary care (PINCER Trial), evaluate pharmacists’ assessment of the training, and the time implications of undertaking the training. Methods: Six pharmacists received training, which included training on root cause analysis and educational outreach, to enable them to deliver the PINCER Trial intervention. This was evaluated using self-report questionnaires at the end of each training session. The time taken to complete each session was recorded. Data from the evaluation forms were entered onto a Microsoft Excel spreadsheet, independently checked and the summary of results further verified. Frequencies were calculated for responses to the three-point Likert scale questions. Free-text comments from the evaluation forms and pharmacists’ diaries were analysed thematically. Key findings: All six pharmacists received 22 hours of training over five sessions. In four out of the five sessions, the pharmacists who completed an evaluation form (27 out of 30 were completed) stated they were satisfied or very satisfied with the various elements of the training package. Analysis of free-text comments and the pharmacists’ diaries showed that the principles of root cause analysis and educational outreach were viewed as useful tools to help pharmacists conduct pharmaceutical interventions in both the study and other pharmacy roles that they undertook. The opportunity to undertake role play was a valuable part of the training received. Conclusions: Findings presented in this paper suggest that providing the PINCER pharmacists with training in root cause analysis and educational outreach contributed to the successful delivery of PINCER interventions and could potentially be utilised by other pharmacists based in general practice to deliver pharmaceutical interventions to improve patient safety.

Análise das condições ergonômicas da situação de trabalho dos auxiliares de enfermagem em uma unidade de interação hospitalar

O objetivo do presente estudo foi investigar as condições ergonômicas da situação de trabalho dos Auxiliares de Enfermagem em uma unidade de clínica geral de um hospital privado na cidade de Curitiba, Paraná, bem como sugerir melhorias a partir da situação caracterizada. Com a aplicação do método da Análise Ergonômica do Trabalho (AET), pôde-se verificar a realidade desses profissionais, caracterizando suas tarefas, registrando a existência de distanciamento entre tarefa prescrita e real. Os resultados obtidos evidenciaram problemas no âmbito organizacional como a montagem inadequada da escala de divisão de pacientes, o quadro de pessoal abaixo da exigência mínima estabelecida pelo Conselho Federal de Enfermagem (COFEN), a falta e a má conservação de materiais e equipamentos e, em relação ao posto de trabalho, o dimensionamento inadequado dos espaços para trânsito de pessoas e equipamentos. Concluiu-se que os problemas de maior relevância são de origem organizacional e que os mesmos favorecem e, até mesmo, intensificam os relativos ao posto de trabalho, contribuindo para o elevado índice de atestados e insatisfação entre os Auxiliares de Enfermagem. O estudo é finalizado com sugestões de melhorias, entre elas, o redimensionamento do número de leitos nas enfermarias e quadro de pessoal, promoção de rodízio dos Auxiliares de Enfermagem entre postos de diferentes níveis de exigência, escalonamento apropriado na distribuição de pacientes de acordo com a gravidade do quadro clínico, formação de comitês com reuniões periódicas para discussão de problemas existentes e outras possíveis soluções.

O consentimento informado: Qual o seu real valor na prática médica?

Trata-se de um artigo que comenta sobre a real importância do Termo de Consentimento Informado na prática médica. Este documento tem sido cada vez mais usado como uma prática defensiva, a fim de constituir provas para defesa de um eventual processo judicial de responsabilidade médica, desvirtuando assim a idéia original, que seria a de respeitar a autonomia do paciente e delimitar a responsabilidade médica. O documento tem como objetivo mostrar que o médico cumpriu com seu dever de informar. Seu grande valor reside nos casos onde existam riscos de danos irreversíveis ao paciente. Conclui-se, porém, que um prontuário bem elaborado onde se inclui o registro das informações que foram transmitidas, bem como o grau de participação dos pacientes e seus familiares nas decisões terapêuticas, também deve ter valor ético e jurídico semelhante do TCI.

Atitudes distintas de profssionais de diferentes especialidades médicas relacionadas à autonomia e aspectos jurídicos no cuidado de pacientes com demência

The evaluation of competence of Alzheimer's disease (AD) patients to assume personal or collective responsibilities and the resulting legal implications is a relevant issue. Objectives: The aim of this study was to evaluate the attitudes of different medical specialists towards the disability of patients with Alzheimer's disease and practitioners' competence to interfere with decision-making autonomy. Methods: Professionals from different areas (Neurology, Psychiatry, Geriatrics, and General Practice) were interviewed by one of the authors, after being presented a fictitious clinical case which raised several topics, namely: [1] Critical judgment and capacity of the patient to take decisions related to daily activities; [2] The role of family physicians in nominating trustees and caregivers. Results: Answers to the first question did not differ regarding degree of preservation of awareness but at least 25% stressed that the patient must be carefully listened to, independent of caregiver or legal representative opinion. There were significant knowledge gaps in responses to the second question. Half of the physicians interviewed did not have adequate information about the legal aspects of caring for patients with Alzheimer's disease. Conclusions: Legal aspects is a topic that must be incorporated into professional training in order to improve attitudes toward the long-term management of patients with dementia.

Adverse drug reaction as cause of hospital admission of elderly people: a pilot study

The objective of this study was to estimate the prevalence of adverse drug reactions (ADR) related to hospital admission of elderly people, identifying the use of potentially inappropriate medication (PIM), the ADR and the risk factors associated with the hospitalization. A cross-sectional study was conducted in a private hospital of São Paulo State, Brazil. All patients aged ≥ 60 years, admitted in the general practice ward in May 2006 were interviewed about the drugs used and the symptoms/complaints that resulted in hospitalization. More than a half (54.5 %) of elderly hospitalizations were related with ADR. The therapeutic classes involved with ADR were: cardiovascular (37.7 %), central nervous (34.6 %) and respiratory (5.7 %). The ADR observed were disorders in circulatory (28.4 %), digestive (20.0 %) and respiratory (18.9 %) tracts. 27 elderly had made PIM and in 20 of them this was the cause of hospitalization. Polypharmacy was an ADR risk factor (p = 0.021).These data allows the healthcare professionals upgrade, qualifying them in pharmcovigilance.

Saúde da Família: O desafio de uma atenção coletiva

The Family Health Strategies, incorporated by the Ministry of Health in 1994, has consolidated the national policy of health care that has as its main care focus the family. In this model, this institution constitutes the first object of attention, understood from its environment and interaction. In recent decades, the Brazilian family structure is suffering profound changes that directly affect the practices of health care. This study redeem the family concepts and ideas and their social representations and still prove and present the importance and the necessity of the use of these ample instruments of collective boarding in health area: the APGAR, the genogram and eco-map, using the environment observation and family history - crucial factors to the reality of the nuclear family diagnosis - for further planning of health action strategies. It was concluded that the current structure of the family require training from the health teams, for physical, cultural, biological and social points of the family context for the correct use of the instruments cited, important tools for collective approach in the public health area.

Análise do conhecimento dos cirurgiões dentistas sobre plano de tratamento das injúrias do ligamento periodontal após traumatismo dentoalveolar

O diagnóstico preciso e a elaboração de um plano de tratamento adequado podem constituir uma tarefa bastante complexa, especialmente nos traumatismos dentoalveolares, pois necessitam de uma abordagem multidisciplinar e conhecimento sobre o processo de reparo após o traumatismo. O objetivo do trabalho foi analisar o conhecimento dos cirurgiões dentistas sobre plano de tratamento das injúrias do ligamento periodontal após traumatismo dentoalveolar. Para tanto, a partir de um questionário, foram abordadas perguntas referentes ao perfil dos profissionais entrevistados e conduta frente às injúrias do ligamento periodontal (concussão, subluxação, luxação extrusiva, luxação lateral e luxação intrusiva) ocasionadas por traumatismo dentoalveolar. Seiscentos e noventa e três cirurgiões dentistas que participaram da 23ª Reunião Anual da SBPqO (2006) responderam o questionário e os dados obtidos foram submetidos à análise descritiva, enquanto o teste estatístico foi aplicado para demonstrar as freqüências e o nível de significância entre as variáveis (Teste qui-quadrado ou Teste Exato de Fisher). De acordo com os resultados obtidos, grandes dificuldades foram encontradas com relação ao plano de tratamento das luxações extrusiva, lateral e intrusiva. De maneira geral, a especialidade não influenciou na elaboração de planos adequados para as injúrias mais complexas. Foi possível concluir que os cirurgiões dentistas não apresentam conhecimento suficiente para tratar de maneira adequada as injúrias mais severas do ligamento periodontal após traumatismo dentoalveolar

Multivariate approach in the selection of superior soybean progeny which carry the RR gene

Efficiency in the use of genetic variability, whether existing or created, increases when properly explored and analysed. Incorporation of biotechnology into breeding programs has been the general practice. The challenge for the researcher is the constant development of new and improved cultivars. The aim of this experiment was to select progenies with superior characteristics, whether or not carriers of the RR gene, derived from bi-parental crosses in the soybean, with the help of multivariate techniques. The experiment was carried out in a family-type experimental design, including controls, during the agricultural year 2010/2011 and 2011/2012 in Jaboticabal in the Brazilian State of São Paulo. From the F3 generation, phenotypically superior plants were selected, which were evaluated for the following traits: number of days to flowering; number of days to maturity; height of first pod insertion; plant height at maturity; lodging; agronomic value; number of branches; number of pods per plant; 100-seed weight; number of seeds per plant; grain yield per plant. Given the results, it appears possible to select superior progeny by principal component analysis. Cluster analysis using the K-means method links progeny according to the most important characteristics in each group and identifies, by the Ward method and by means of a dendrogram, the structure of similarity and divergence between selected progeny. Both methods are effective in aiding progeny selection.
