Educational Group Practices in Primary Care: Interaction Between Professionals, Users and Knowledge

OBJECTIVE To investigate the concept understood by Family Healthcare Strategy (ESF) professionals of knowledge, education and subjects participating in learning activities. METHOD Qualitative study carried out with the ESF professionals with university degree, members of the healthcare staff who undertook educational health group activities at Basic Healthcare Units (UBS) in Belo Horizonte. The following triangulation techniques were used: participant observation, photos and field notes; interviews with professionals; and document analysis. RESULTS We identified three interaction patterns that are different from each other. Firstly, the professional questions, listens and provides information to users, trusting in the transmission of knowledge; secondly, the professional questions and listens, trusting that users can learn from each other; thirdly, the professional questions, listens, discusses and produces knowledge with users, both teaching and learning from each other. CONCLUSION There are educational practices that include unique methods capable of creating a militant space for citizenship engagement.

Primary Health Care from the perception of women living in a rural area

AbstractOBJECTIVEUnderstanding the perception of women living in a rural area about the actions and services of Primary Health Care (PHC) in a municipality of southern Brazil, which is the only one regarded as predominantly rural.METHODA descriptive study of qualitative approach, carried out with women who lived in the countryside and required health services in the 15 days prior to collection.RESULTSThe results registered low fidelity to PHC attributes, focusing its functional axis on sickness, transforming the unit into small points of emergency care and a bureaucratic place where patients are referred to other types of services. The quality of service offered is compromised to offering quick, fragmented and unequal treatment in the rural context.CONCLUSIONThe findings of this study highlight the need for greater efforts in order to adequate the new care model in the development of appropriate actions as designated by PHC in the rural context studied.

Effective continuing professional development for translating shared decision making in primary care: A study protocol.

Background: Shared decision making (SDM) is a process by which a healthcare choice is made jointly by the healthcare professional and the patient. SDM is the essential element of patient-centered care, a core concept of primary care. However, SDM is seldom translated into primary practice. Continuing professional development (CPD) is the principal means by which healthcare professionals continue to gain, improve, and broaden the knowledge and skills required for patient-centered care. Our international collaboration seeks to improve the knowledge base of CPD that targets translating SDM into the clinical practice of primary care in diverse healthcare systems. Methods: Funded by the Canadian Institutes of Health Research (CIHR), our project is to form an international, interdisciplinary research team composed of health services researchers, physicians, nurses, psychologists, dietitians, CPD decision makers and others who will study how CPD causes SDM to be practiced in primary care. We will perform an environmental scan to create an inventory of CPD programs and related activities for translating SDM into clinical practice. These programs will be critically assessed and compared according to their strengths and limitations. We will use the empirical data that results from the environmental scan and the critical appraisal to identify knowledge gaps and generate a research agenda during a two-day workshop to be held in Quebec City. We will ask CPD stakeholders to validate these knowledge gaps and the research agenda. Discussion: This project will analyse existing CPD programs and related activities for translating SDM into the practice of primary care. Because this international collaboration will develop and identify various factors influencing SDM, the project could shed new light on how SDM is implemented in primary care.

Opportunistic screening actions for breast cancer performed by nurses working in primary health care

Abstract OBJECTIVE To identify opportunistic screening actions for breast cancer performed by nurses working in primary health care units in Ribeirão Preto, São Paulo. METHOD Cross-sectional study with 60 nurses from 28 units, who had been working for at least one year in the public municipal health care network. Data were collected between December 2013 and March 2014, by means of a questionnaire, using descriptive analysis and the software IBM SPSS version 20 and Microsoft Excel 2010. RESULTS The results showed that 71.7% of the participants questioned their female patients as for risk factors for breast cancer, mainly during nursing consultation; 70.0% oriented users about the age to perform clinical breast exam, whereas 30.0% did not due to lack of knowledge and time; 60.0% explained about the age to perform mammogram; 73.3% did not refer patients with suspicious breast exam results to the referral department, citing scheduling as the main obstacle to referral. Educational activities were not performed by 78.3% of participants. CONCLUSION Investment is needed in professional training and management of breast cancer screening.

Time standards of nursing in Primary Health Care: an observational study

Abstract OBJECTIVE To determine time standards for interventions and activities conducted by nursing professionals in Family Health Units (FHU) in Brazil to substantiate the calculation of work force. METHOD This was an observational study carried out in 27 FHU, in 12 municipalities in 10 states, in 2013. In each unit, nursing professionals were observed every 10 minutes, for eight work hours, on five consecutive days via the work sampling technique. RESULTS A total of 32,613 observations were made, involving 47 nurses and 93 nursing technicians/assistants. Appointments were the main intervention carried out by nurses, with a mean time of 25.3 minutes, followed by record-keeping, which corresponded to 9.7%. On average, nursing technicians/assistants spent 6.3% of their time keeping records and 30.6 intervention minutes on immunization/vaccination control. CONCLUSION The study resulted in standard times of interventions carried out by the FHU nursing team, which can underpin the determination of nursing staff size and human resource policies. Furthermore, the study showed the panorama of interventions currently employed, allowing for the work process to be reviewed and optimized.

An integrative review of drug utilization by the elderly in primary health care

ABSTRACT OBJECTIVE To identify knowledge produced about drug utilization by the elderly in the primary health care context from 2006 to 2014. METHOD An integrative review of the PubMed, LILACS, BDENF, and SCOPUS databases, including qualitative research papers in Portuguese, English, and Spanish. It excluded papers with insufficient information regarding the methodological description. RESULTS Search found 633 papers that, after being subjected to the inclusion and exclusion criteria, made up a corpusof 76 publications, mostly in English and produced in the United States, England, and Brazil. Results were pooled in eight thematic categories showing the current trend of drug use in the elderly, notably the use of psychotropics, polypharmacy, the prevention of adverse events, and adoption of technologies to facilitate drug management by the elderly. Studies point out the risks posed to the elderly as a consequence of changes in metabolism and simultaneous use of several drugs. CONCLUSION There is strong concern about improving communications between professionals and the elderly in order to promote an exchange of information about therapy, and in this way prevent major health complications in this population.

Characterization of Epstein-Barr virus-specific immune responses and of the novel cytokine interleukin-26 in patients with multiple sclerosis

RÉSUMÉ La sclérose en plaques (SEP) est une maladie démyélinisante du système nerveux central (SNC) qui touche le plus souvent de jeunes femmes. Bien qu'elle ait été décrite pour la première fois il y a plus de 200 ans, son étiologie n'est pas encore complètement comprise. Contrairement à d'autres maladies purement génétiques, l'épidémiologie de la SEP ne peut être que partiellement expliquée par des facteurs génétiques. Ceci suggère que des facteurs environnementaux pourraient être impliqués dans la pathogenèse de la SEP. Parmi ceux-ci, le virus d'Epstein-Barr (EBV) est un excellent candidat, comme cela a été démontré par de larges études séroépidémiologiques ainsi que pax l'évaluation de la réponse cellulaire dans le sang. Bien que le SNC soit en fait la cible des réponses immunitaires anormales dans la SEP, peu d'études ont été accomplies sur les réponses immunitaires spécifiques à EBV dans ce compartiment. Ceci est particulièrement vrai chez des patients vivants chez lesquels des biopsies sont rarement effectuées, ainsi que pour les réponses cellulaires car très peu de cellules immunitaires peuvent être obtenues du SNC. Nous avons donc développé des conditions de cultures et un readout nous permettant d'étudier le nombre réduit de cellules disponibles dans le liquide céphalo-rachidien (LCR), qui représente le seul matériel pouvant être obtenu du SNC de patients SEP vivants. Nous avons trouvé que les réponses cellulaires et humorales spécifiques à EBV étaient augmentées dans le LCR des patients SEP comparé à du sang pairé, ainsi que par rapport à des patients avec d'autres maladies neurologiques inflammatoires et noninflammatoires. Afin de déterminer si les réponses immunitaires augmentées contre EBV étaient spécifiques à ce virus ou si elles reflétaient simplement une hyperactivation immunitaire aspécifique, nous avons comparé les réponses spécifiques à EBV avec celles spécifiques au cytomegalovirus (CNN). En effet, comme EBV, CNN est un herpesvirus neurotropique qui peut établir des infections latentes, mais ce dernier n'est pas considéré comme étant associé à la SEP. De façon intéressante, les réponses immunitaires spécifiques à CNN trouvées dans le LCR étaient plus basses que dans le sang, et ceci dans toutes les catégories de patients. Ces données suggèrent qu'une réactivation d'EBV pourrait avoir lieu dans le SNC des patients SEP à un stade précoce de la maladie et renforcent fortement l'hypothèse qu'EBV pourrait avoir un rôle déclencheur dans cette maladie. Ainsi, il pourrait être intéressant d'explorer si un traitement ou un vaccin efficace contre EBV peut prévenir le développement de la SEP. On ne connaît toujours pas la raison pour laquelle les réponses immunitaires spécifiques à EBV sont augmentées chez les patients SEP. Une hypothèse est que la réponse immunitaire est qualitativement différente chez les patients SEP par rapports aux contrôles. Pour examiner ceci, nous avons évalué le profile cytokinique de lymphocytes T CD4+ et CD8+ stimulés par EBV, mais nous n'avons pas pu mettre en évidence de différence remarquable entre patients SEP et sujets sains. Cette question reste donc ouverte et d'autres études sont justifiées. Il n'existe pas de marqueur fiable de la SEP. Ici, nous avons trouvé que la cytokine IL-26, récemment décrite, était augmentée dans les lymphocytes T CD8+ des patients avec une SEP secondairement progressive comparé à des patients SEP en poussée, des patients avec une SEP primairement progressive, des patients avec d'autres maladies neurologiques inflammatoires, ou des sujets sains. De plus, nous avons identifié des types de cellules dérivées du cerveau (astrocytes, oligodendrocytes et neurones) qui exprimaient le récepteur de l'IL-26. Ceci ouvre la voie à d'autres études afin de mieux comprendre la fonction de l'II.-26 et son interaction avec la. SEP. SUMMARY : Multiple sclerosis (MS) is a demyelinating disease affecting the central nervous system (CNS), mostly in young female adults. Although it was first described 200 years ago, its etiology is still not completely understood. Contrary to other purely genetic diseases, genetics can explain only part of MS epidemiology. Therefore, environmental factors that might be involved in MS pathogenesis were searched for. Among them, Epstein-Barr virus (EBV) is a strong potential candidate, such as shown by large seroepidemiological studies and cellular immune response assessments in the blood. Although the CNS is the actual target of abnormal immune responses in MS, few studies have been performed on EBV-specific immune responses in this compartment. This is particularly true for live patients, from which biopsy material is almost never available, and for cellular immune responses, since very few immune cells are available from the CNS. We therefore developed culture conditions and a readout that were compatible with the study of the reduced number of cells found in the cerebrospinal fluid (CSF), the only readily available material from the CNS of live ' MS patients. We found that EBV-specific cellular and humoral immune responses were increased in the CSF of MS patients as compared with paired blood, as well as compared with the CSF of patients with other inflammatory and non-inflammatory neurological diseases. To determine whether the enhanced immune responses against EBV were specific of this virus or simply reflected an aspecific immune hyperactivation, we compared the EBV- with the cytomegalovirus (CMV)-specific immune responses. Indeed, like EBV, CMV is a neurotrophic herpesvirus that can establish latent infections, but the latter is not considered to be associated with MS. Interestingly, CSF CMV-specific immune responses were lower than blood ones and this, in all patient categories. These findings suggest that EBV reactivation may be taking place in the CNS of patients at the early stages of MS and strengthen the hypothesis that EBV may have a triggering role in this disease. Therefore, it might be interesting to explore whether an efficient anti-EBV drug or vaccine is able to prevent MS development. The reason why EBV-specific immune responses are increased in MS patients is still missing. One hypothesis might be that the immune response against EBV is qualitatively different in MS patients as compared with controls. To examine this, we assessed the cytokine mRNA profile of EBV-stimulated CD4+ and CD8+ T cells, but could not find any remarkable difference between MS patients and healthy controls. Therefore, this question remains open and fiirther studies are warranted. Reliable disease markers are lacking for MS. Here, we found that the recently described cytokine IL-26 was increased in CD8+ T cells of patients with secondary progressive MS as compared with relapsing MS, primary progressive MS, other inflammatory neurological diseases and healthy controls. Moreover, we identified brain cell types (astrocytes, oligodendrocytes and neurons) that expressed the IL-26 receptor, paring the way for further studies to understand IL-26 function and its interaction with MS.

Completing contracts ex post: How car manufacturers manage car dealers

This article illustrates how contracts are completed ex post in practice and, in so doing, indirectly suggests what the real function of contracts may be. Our evidence comes from the contracts between automobile manufacturers and their dealers in 23 dealership networks in Spain. Franchising dominates automobile distribution because of the need to decentralize pricing and control of service decisions. It motivates local managers to undertake these activities at minimum cost for the manufacturer. However, it creates incentive conflicts, both between manufacturers and dealers and among dealers themselves, concerning the level of sales and service provided. It also holds potential for expropriation of specific investments. Contracts deal with these conflicts by restricting dealers decision rights and granting manufacturers extensive completion, monitoring and enforcement powers. The main mechanism that may prevent abuse of these powers is the manufacturers reputational capital.

Spinning welfare: The gains from process innovation in cotton and car production

Economists and economic historians want to know how much better life is today than in the past.Fifty years ago economic historians found surprisingly small gains from 19th century US railroads,while more recently economists have found relatively large gains from electricity, computers and cellphones. In each case the implicit or explicit assumption is that researchers were measuring the valueof a new good to society. In this paper we use the same techniques to find the value to society ofmaking existing goods cheaper. Henry Ford did not invent the car, and the inventors of mechanisedcotton spinning in the industrial revolution invented no new product. But both made existing productsdramatically cheaper, bringing them into the reach of many more consumers. That in turn haspotentially large welfare effects. We find that the consumer surplus of Henry Ford s production linewas around 2% by 1923, 15 years after Ford began to implement the moving assembly line, while themechanisation of cotton spinning was worth around 6% by 1820, 34 years after its initial invention.Both are large: of the same order of magnitude as consumer expenditure on these items, and as largeor larger than the value of the internet to consumers. On the social savings measure traditionally usedby economic historians, these process innovations were worth 15% and 18% respectively, makingthem more important than railroads. Our results remind us that process innovations can be at least asimportant for welfare and productivity as the invention of new products.

Prediction of myocardial infarction size using the SYNTAX score in patients treated with primary percutaneous coronary intervention for acute ST- segment elevation myocardial infarction

Objectives The relevance of the SYNTAX score for the particular case of patients with acute ST- segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI)  has previously only been studied in the setting of post hoc analysis of large prospective randomized clinical trials. A "real-life" population approach has never been explored before. The aim of this study was to evaluate the impact of the SYNTAX score for the prediction of the myocardial infarction size, estimated by the creatin-kinase (CK) peak value, using the SYNTAX score in patients treated with primary coronary intervention for acute ST-segment elevation myocardial infarction. Methods The primary endpoint of the study was myocardial infarction size as measured by the CK peak value. The SYNTAX score was calculated retrospectively in 253 consecutive patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) in a large tertiary referral center in Switzerland, between January 2009 and June 2010. Linear regression analysis was performed to compare myocardial infarction size with the SYNTAX score. This same endpoint was then stratified according to SYNTAX score tertiles: low <22 (n=178), intermediate [22-32] (n=60), and high >=33 (n=15). Results There were no significant differences in terms of clinical characteristics between the three groups. When stratified according to the SYNTAX score tertiles, average CK peak values of 1985 (low<22), 3336 (intermediate [22-32]) and 3684 (high>=33) were obtained with a p-value <0.0001. Bartlett's test for equal variances between the three groups was 9.999 (p-value <0.0067). A moderate Pearson product-moment correlation coefficient (r=0.4074) with a high statistical significance level (p-value <0.0001) was found. The coefficient of determination (R^2=0.1660) showed that approximately 17% of the variation of CK peak value (myocardial infarction size) could be explained by the SYNTAX score, i.e. by the coronary disease complexity. Conclusion In an all-comers population, the SYNTAX score is an additional tool in predicting myocardial infarction size in patients treated with primary percutaneous coronary intervention (PPCI). The stratification of patients in different risk groups according to SYNTAX enables to identify a high-risk population that may warrant particular patient care.

The chemokine receptor CXCR4 strongly promotes neuroblastoma primary tumour and metastatic growth, but not invasion.

Neuroblastoma (NB) is a heterogeneous, and particularly malignant childhood neoplasm in its higher stages, with a propensity to form metastasis in selected organs, in particular liver and bone marrow, and for which there is still no efficient treatment available beyond surgery. Recent evidence indicates that the CXCR4/CXCL12 chemokine/receptor axis may be involved in promoting NB invasion and metastasis. In this study, we explored the potential role of CXCR4 in the malignant behaviour of NB, using a combination of in vitro functional analyses and in vivo growth and metastasis assessment in an orthotopic NB mouse model. We show here that CXCR4 overexpression in non-metastatic CXCR4-negative NB cells IGR-NB8 and in moderately metastatic, CXCR4 expressing NB cells IGR-N91, strongly increased tumour growth of primary tumours and liver metastases, without altering the frequency or the pattern of metastasis. Moreover shRNA-mediated knock-down experiments confirmed our observations by showing that silencing CXCR4 in NB cells impairs in vitro and almost abrogates in vivo growth. High levels of CXCL12 were detected in the mouse adrenal gland (the primary tumour site), and in the liver suggesting a paracrine effect of host-derived CXCL12 on NB growth. In conclusion, this study reveals a yet unreported NB-specific predominant growth and survival-promoting role of CXCR4, which warrants a critical reconsideration of the role of CXCR4 in the malignant behaviour of NB and other cancers.

Clinical characteristics and outcome of isolated extracerebral relapses of primary central nervous system lymphoma: a case series.

There is very limited data on isolated systemic relapses of primary central nervous system lymphomas (PCNSL). We retrospectively reviewed the clinical characteristics and outcome of 10 patients with isolated systemic disease among 209 patients with PCNSL mainly treated with methotrexate-based chemotherapy (CT) with or without radiation therapy (RT). Isolated systemic relapse remained rare (4.8%, 10/209 patients). Median time from initial diagnosis to relapse was 33 months (range, 3-94). Sites of relapse were mostly extranodal. Three patients presented with early extra-cerebral (EC) relapse 3, 5 and 8 months from the beginning of initial treatment, respectively, and 7 patients had later relapses (range, 17-94 months). Treatment at relapse included surgery alone, RT alone, CT with or without radiotherapy, or CT with autologous stem cell transplantation (ASCT). Median overall survival (OS) after relapse was 15.5 months (range, 5.8-24.5) compared to 4.6 months (range, 3.6-6.5) for patients with central nervous system (CNS) relapse (p = 0.35). In conclusion, isolated systemic relapses exist but are infrequent. Early EC relapse suggests the presence of systemic disease undetectable by conventional evaluation at initial diagnosis. Patient follow-up must be prolonged because systemic relapse can occur as late as 10 years after initial diagnosis. Whether EC relapses of PCNSL have a better prognosis than CNS relapses needs to be assessed in a larger cohort. Copyright © 2010 John Wiley & Sons, Ltd.
