Moderating effects of contextual factors on relationship between pharmaceutical marketing strategies and physician prescription decision: A review

Decision–making by physicians on patients’ treatment has received increased research attention. Research on the effect of marketing strategies on prescription behaviour has tended to generate controversial results. While some researchers reported a strong influence, some found only moderate effects, while others find no influence at all. The main objective of this paper is to review the influence of the marketing strategies by pharmaceutical firms and contextual factors on physician attitude to drug prescription. The paper presents comprehensive information on pharmaceutical marketing efforts through exhaustive review of relevant literature, and identifies the moderating effects of contextual factors on physician prescribing decisions. It also presents a crucial conceptual model for explaining the theoretical linkages between marketing strategies of pharmaceutical firms, contextual factors and the decision of the physician regarding drug prescription.

How can personal role engagement lead to increased engagement? The roles of meaningfulness and perceived line manager relations

There is an increasing need to understand the psychological processes that link personal development with employee engagement, particularly the boundary conditions at which these occur. The current study sought to meet this need by testing whether perceived opportunities for development are positively associated with job engagement indirectly through the experience of meaningfulness, and whether this indirect relationship is conditional on the level of perceived line manager relations. Questionnaire data was collected from 152 UK workers from a range of occupations and organizations. The results found support for all the hypotheses. In particular, the positive effects of perceived opportunities for development on job engagement (measured one month later) via meaningfulness were only significant for those who perceived that they had a good relationship with their line manager. Thus, there is a need for line managers to develop high quality relationships with their direct reports in order for development practices to translate into positive psychological outcomes. Engagement theory could be advanced by further understanding broaden-and-build and social exchange processes.

Efecto del consumo concomitante de inhibidores de bomba protones y levotiroxina : revisión sistemática y metaanálisis

Estudios afirman que la acidez gástrica es importante en la absorción de levotiroxina (LT4) con resultados controversiales sobre la interacción entre inhibidores de bomba de protones (IBP) y LT4. El objetivo del estudio fue establecer el efecto del uso concomitante de LT4 e IBP en los niveles de TSH en pacientes adultos con hipotiroidismo primario. Se realizó una revisión sistemática mediante búsqueda en Medline, Embase, Lilacs, Bireme, Scielo, Cochrane y Universidad de York, Access Pharmacy, Google Scholar, Dialnet y Opengray. La búsqueda no se limito por lenguaje. Se evaluó el efecto en la diferencia de medias de TSH luego del consumo de LT4 y luego del consumo concomitante con IBP. Se hizo un metaanálisis, análisis de subgrupos y análisis de sensibilidad utilizando el programa Review Manager 5.3. Se eligieron 5 artículos para el análisis cualitativo y 3 para el metaanálisis. La calidad de los estudios fue buena y el riesgo de sesgos bajo. La diferencia de medias obtenida fue 0.21 mUI/L (IC95%: 0.02-0.40; p=0.03; I2:0%). En el análisis de subgrupos en pacientes mayores de 55 años la diferencia de medias fue 0.21 mUI/L (IC95%: 0.01-0.40; p=0.27; I2:19%). En el análisis de sensibilidad se excluyo el estudio con mayor muestra y la diferencia de medias fue 0.49 mUI/L (IC95%: -0.12 a 1.11; p=0.12; I2:0%). La diferencia de medias de TSH luego del consumo concomitante no se considera clínicamente significativa pues no representa riesgo para el paciente. Son necesarios estudios clínicos aleatorizados y evaluar el efecto en los niveles de T4 libre.

Using a Dialogue Manager to Improve Semantic Web Search

Question Answering systems that resort to the Semantic Web as a knowledge base can go well beyond the usual matching words in documents and, preferably, find a precise answer, without requiring user help to interpret the documents returned. In this paper, the authors introduce a Dialogue Manager that, through the analysis of the question and the type of expected answer, provides accurate answers to the questions posed in Natural Language. The Dialogue Manager not only represents the semantics of the questions, but also represents the structure of the discourse, including the user intentions and the questions context, adding the ability to deal with multiple answers and providing justified answers. The authors’ system performance is evaluated by comparing with similar question answering systems. Although the test suite is slight dimension, the results obtained are very promising.

[principles Of Universality, Comprehensiveness And Equity In A Hearing Health Care Service].

This article analyzed whether the practices of hearing health care were consistent with the principles of universality, comprehensiveness and equity from the standpoint of professionals. It involved qualitative research conducted at a Medium Complexity Hearing Health Care Center. A social worker, three speech therapists, a physician and a psychologist constituted the study subjects. Interviews were conducted as well as observation registered in a field diary. The thematic analysis technique was used in the analysis of the material. The analysis of interviews resulted in the construction of the following themes: Universality and access to hearing health, Comprehensive Hearing Health Care and Hearing Health and Equity. The study identified issues that interfere with the quality of service and run counter to the principles of Brazilian Unified Health System. The conclusion reached was that a relatively simple investment in training and professional qualification can bring about significant changes in order to promote a more universal, comprehensive and equitable health service.

[demographic And Clinical Features Of Patients With Rheumatoid Arthritis In Piauí, Brazil--evaluation Of 98 Patients].

Brazilian epidemiological studies on rheumatoid arthritis are scarce, mainly in the northeast; thus many data currently available originate from the international literature. To describe demographic, clinical and serological characteristics of patients with rheumatoid arthritis (RA) followed-up by the same physician, in state of Piauí, Brazil. Data were collected between August 2010 and March 2013, in three health services of Piauí that provided health care in Rheumatology: a university-affiliated hospital, a public outpatient clinic and a private clinic. The numbers represent mean ± SD or percentage: 47.5±11.03 years-old non-Caucasian woman, non-smoker (59.2%), low educational level, mean disease duration of 7.7 years ± 7.6, and major extra-articular manifestations were rheumatoid nodules (19.4%) and sicca syndrome (46.9%). Features of rheumatoid arthritis obtained in this study are similar to those found in some national and international studies, but we observed higher female preponderance and illiteracy rate, in addition to a moderately severe erosive disease on average, with frequent sicca and other extra-articular manifestations.

Motivating Medical Students To Learn Basic Science Concepts Using Chronic Myeloid Leukemia As An Integration Theme.

To report on the use of chronic myeloid leukemia as a theme of basic clinical integration for first year medical students to motivate and enable in-depth understanding of the basic sciences of the future physician. During the past thirteen years we have reviewed and updated the curriculum of the medical school of the Universidade Estadual de Campinas. The main objective of the new curriculum is to teach the students how to learn to learn. Since then, a case of chronic myeloid leukemia has been introduced to first year medical students and discussed in horizontal integration with all themes taught during a molecular and cell biology course. Cell structure and components, protein, chromosomes, gene organization, proliferation, cell cycle, apoptosis, signaling and so on are all themes approached during this course. At the end of every topic approached, the students prepare in advance the corresponding topic of clinical cases chosen randomly during the class, which are then presented by them. During the final class, a paper regarding mutations in the abl gene that cause resistance to tyrosine kinase inhibitors is discussed. After each class, three tests are solved in an interactive evaluation. The course has been successful since its beginning, 13 years ago. Great motivation of those who participated in the course was observed. There were less than 20% absences in the classes. At least three (and as many as nine) students every year were interested in starting research training in the field of hematology. At the end of each class, an interactive evaluation was performed and more than 70% of the answers were correct in each evaluation. Moreover, for the final evaluation, the students summarized, in a written report, the molecular and therapeutic basis of chronic myeloid leukemia, with scores ranging from 0 to 10. Considering all 13 years, a median of 78% of the class scored above 5 (min 74%-max 85%), and a median of 67% scored above 7. Chronic myeloid leukemia is an excellent example of a disease that can be used for clinical basic integration as this disorder involves well known protein, cytogenetic and cell function abnormalities, has well-defined diagnostic strategies and a target oriented therapy.

Synchronous Oral Paracoccidioidomycosis And Pulmonary Tuberculosis In An Immunocompetent Patient.

Paracoccidioidomycosis (PCM) and tuberculosis (TB) are chronic granulomatous infectious diseases, in which the main form of contraction is through inhalation of the microorganism-Paracoccidioides brasiliensis and Mycobacterium tuberculosis. Oral involvement of PCM is observed in up to 70 % of the cases and usually presents clinically as ulcerations with granular surface showing tiny hemorrhagic areas. Oral presentation of TB is rare with prevalence smaller than 0.5 % of all cases. Clinical presentation of oral TB mainly consists of single ulcers with irregular limits and necrotic base. A 70-year-old immunocompetent man presented simultaneously oral PCM and pulmonary TB. Medical history revealed a previous diagnosis of pulmonary TB; however, even under treatment for TB, the patient remained with oral lesions and intense pulmonary fibrosis. The physician requested P. brasiliensis serological analysis, which resulted positive. Although the combination of PCM and TB has been reported in the literature, it is still considered an uncommon condition and their diagnosis may represent a challenge to healthcare professionals because of the similarity between their clinical and radiological presentations.

Patient education in glaucoma: what do patients know about glaucoma?

PURPOSE: To evaluate the knowledge glaucoma patients have about their disease and its treatment. METHODS: One hundred and eighty-three patients were interviewed at the Glaucoma Service of Wills Eye Hospital (Philadelphia, USA, Group 1) and 100 at the Glaucoma Service of University of Campinas (Campinas, Brazil, Group 2). An informal, relaxed atmosphere was created by the interviewer before asking a list of 18 open-ended questions. RESULTS: In Group 1, 44% of the 183 patients did not have an acceptable idea about what glaucoma is, 30% did not know the purpose of the medications they were taking, 47% were not aware of what was an average intraocular pressure, and 45% did not understand why visual fields were examined. In Group 2, 54% gave unsatisfactory answers to the question What is glaucoma?, 54% did not know the purpose of the medications they were taking, 80% were not aware of what was an average intraocular pressure, and 94% did not understand why visual fields were examined (p<0.001). Linear regression analysis demonstrated that level of education was positively correlated to knowledge about glaucoma in both groups (r=0.65, p=0.001). CONCLUSION: This study showed that patients' knowledge about glaucoma varies greatly, and that in an urban, American setting, around one third of the patients have minimal understanding, whereas in an urban setting in Brazil around two thirds of patients were lacking basic information about glaucoma. Innovative and effective methods are needed to correct this situation.

Diagnostic agreement between panoramic radiographs and color doppler images of carotid atheroma

The aim of this study was to investigate the agreement between diagnoses of calcified atheroma seen on panoramic radiographs and color Doppler images. Our interest stems from the fact that panoramic images can show the presence of atheroma regardless of the level of obstruction detected by color Doppler images. Panoramic and color Doppler images of 16 patients obtained from the archives of the Health Department of the city of Valença, RJ, Brazil, were analyzed in this study. Both sides of each patient were observed on the images, with a total of 32 analyzed cervical regions. The level of agreement between diagnoses was analyzed using the Kappa statistics. There was a high level of agreement, with a Kappa value of 0.78. In conclusion, panoramic radiographs can help detecting calcifications in the cervical region of patients susceptible to vascular diseases predisposing to myocardial infarction and cerebrovascular accidents. If properly trained and informed, dentists can refer their patients to a physician for a cardiovascular evaluation in order to receive proper and timely medical treatment.

Microlithiasis of the gallbladder: role of endoscopic ultrasonography in patients with idiopathic acute pancreatitis

OBJECTIVES: Causes may be found in most cases of acute pancreatitis, however no etiology is found by clinical, biological and imaging investigations in 30% of these cases. Our objective was to evaluate results from endoscopic ultrasonography (EUS) for diagnosis of gallbladder microlithiasis in patients with unexplained (idiopathic) acute pancreatitis. METHODS: Thirty-six consecutive non-alcoholic patients with diagnoses of acute pancreatitis were studied over a five-year period. None of them showed signs of gallstones on transabdominal ultrasound or tomography. We performed EUS within one week of diagnosing acute pancreatitis. Diagnosis of gallbladder microlithiasis on EUS was based upon findings of hyperechoic signals of 0.5-3.0 mm, with or without acoustic shadowing. All patients (36 cases) underwent cholecystectomy, in accordance with indication from the attending physician or based upon EUS diagnosis. RESULTS: Twenty-seven patients (75%) had microlithiasis confirmed by histology and nine did not (25%). EUS findings were positive in twenty-five. Two patients had acute cholecystitis diagnosed at EUS that was confirmed by surgical and histological findings. In two patients, EUS showed cholesterolosis and pathological analysis disclosed stones not detected by EUS. EUS diagnosed microlithiasis in four cases not confirmed by surgical treatment. In our study, sensitivity, specificity and positive and negative predictive values to identify gallbladder microlithiasis (with 95% confidence interval) were 92.6% (74.2-98.7%), 55.6% (22.7-84.7%), 86.2% (67.4-95.5%) and 71.4% (30.3-94.9%), respectively. Overall EUS accuracy was 83.2%. CONCLUSIONS: EUS is a very reliable procedure to diagnose gallbladder microlithiasis and should be used for the management of patients with unexplained acute pancreatitis. This procedure should be part of advanced endoscopic evaluation.

Critical applications of SW 846 US EPA methods to evaluation of marine samples quality

Technical evaluation of analytical data is of extreme relevance considering it can be used for comparisons with environmental quality standards and decision-making as related to the management of disposal of dredged sediments and the evaluation of salt and brackish water quality in accordance with CONAMA 357/05 Resolution. It is, therefore, essential that the project manager discusses the environmental agency's technical requirements with the laboratory contracted for the follow-up of the analysis underway and even with a view to possible re-analysis when anomalous data are identified. The main technical requirements are: (1) method quantitation limits (QLs) should fall below environmental standards; (2) analyses should be carried out in laboratories whose analytical scope is accredited by the National Institute of Metrology (INMETRO) or qualified or accepted by a licensing agency; (3) chain of custody should be provided in order to ensure sample traceability; (4) control charts should be provided to prove method performance; (5) certified reference material analysis or, if that is not available, matrix spike analysis, should be undertaken and (6) chromatograms should be included in the analytical report. Within this context and with a view to helping environmental managers in analytical report evaluation, this work has as objectives the discussion of the limitations of the application of SW 846 US EPA methods to marine samples, the consequences of having data based on method detection limits (MDL) and not sample quantitation limits (SQL), and present possible modifications of the principal method applied by laboratories in order to comply with environmental quality standards.

O difícil acesso a serviços de média complexidade do SUS: o caso da cidade de São Paulo, Brasil

O acesso aos serviços de média complexidade tem sido apontado, por gestores e pesquisadores, como um dos entraves para a efetivação da integralidade do SUS. Este artigo teve o objetivo de avaliar mecanismos utilizados pela gestão do SUS, no município de São Paulo, para garantir acesso à assistência de média complexidade, durante o período de 2005 a 2008. Optou-se pela estratégia de estudo de caso, utilizando as seguintes fontes de evidência: entrevistas com gestores; grupo focal com usuários e observação participante. Utilizouas técnica de análise temática, a partir do referencial teórico da integralidade da assistência, na dimensão da organização de serviços. Buscou-se descrever os caminhos percorridos pelos usuários para acessar os serviços da média complexidade, a partir da visão dos gestores e dos próprios usuários. A média complexidade foi identificada, pelos gestores, como o "gargalo" do SUS e um dos principais obstáculos para a construção da integralidade. Para enfrentar essa situação, o gestor municipal investiu na informatização dos serviços, como medida isolada e, ainda, sem considerar a necessidade dos usuários. Sendo assim, essa incorporação tecnológica teve pouco impacto na melhoria do acesso, o que se confirmou no relato dos usuários. Discute-se que para o enfrentamento de um problema tão complexo são necessárias ações articuladas, tanto no âmbito da política de saúde, quanto da organização dos serviços, bem como a (re)organização do processo de trabalho em todos os níveis do sistema de saúde.
