Comparison between Brazil and the 30 Most Innovative Countries in the World

Innovation can be defined as the implementation of a new or significantly improved product (good or service), or a process, a new marketing method, a new organizational method in business practices, workplace organization, or external relations. This innovation can be measured by several factors such as investments in research and development, the concentration of high-tech companies traded on the stock exchange, among others. The present study aims to perform a cluster analysis to investigate the behavior of the most innovative countries compared to Brazil. The study contemplates a historical series from the years 2012 to 2015 of the 30 most innovative countries in the world having been added to Brazil. In addition, a series of macroeconomic, political and social variables are considered

La doble ruptura: problemas epistemológicos a partir de la construcción de una base de datos histórica relativa a la conversión forzada

Este articulo muestra algunos problemas epistemológicos derivados de la explotación de los textos recogidos en el proceso e creación de la base de datos del proyecto POCRAM, relativa a la cuestión de la «conversión religiosa» entre la antigüedad tardía y el fin de la edad moderna. Así mismo se hace un balance de la evolución de las humanidades numéricas (especialmente en Francia), así como de los proyectos precedentes en que se inspira la conceptualización de la base. Presentamos nuestro Corpus y las consecuencias de su explotación gracias al uso de diferentes software que provocan una doble ruptura, epistemológica y conceptual  en la forma de entender la historia

Ascher syndrome: Clinical case care and treatment

Presentamos un paciente con “Sindrome de Ascher”. Se trata de una rara entidad benigna, que es una anomalía congénita o adquirida de etiología desconocida. Clínicamente el Síndrome de Ascher, está compuesto por una tríada de signos clínicos: doble labio (siendo el superior el más frecuentemente involucrado), blefarocalasia y bocio no tóxico (agrandamiento tiroideo, no funcional y ausente en aproximadamente la mitad de los casos). Cuando la deformidad labial interfiere con la masticación o provoca groseras alteraciones estéticas, el tratamiento quirúrgico está indicado.We present a case report of patient with Ascher Syndrome. It is a rare entity, benig, with few cases related in the world. Clinically Ascher Syndrome it is an anomaly wich may be either congenital or acquired, composed by three fillings: blepharochalasis, double lip (upper lip is involved more often than the lower, although on occasion both may be involved), and nontoxicthyroid goiter). Apart from a deformity that interferes whit mastication and speech, surgical treatment may be indicated for cosmetic reasons

Chemical composition modulates the adverse effects of particles on the mucociliary epithelium

OBJECTIVE:We compared the adverse effects of two types of real ambient particles; i.e., total suspended particles from an electrostatic precipitator of a steel mill and fine air particles from an urban ambient particulate matter of 2.5 µm, on mucociliary clearance.METHOD:Mucociliary function was quantified by mucociliary transport, ciliary beating frequency and the amount of acid and neutral mucous in epithelial cells through morphometry of frog palate preparations. The palates were immersed in one of the following solutions: total suspended particles (0.1 mg/mL), particulate matter 2.5 µm 0.1 mg/mL (PM0.1) or 3.0 mg/mL (PM3.0) and amphibian Ringer’s solution (control). Particle chemical compositions were determined by X-ray fluorescence and gas chromatography/mass spectrometry.RESULTS:Exposure to total suspended particles and PM3.0 decreased mucociliary transport. Ciliary beating frequency was diminished by total suspended particles at all times during exposure, while particulate matter of 2.5 µm did not elicit changes. Particulate matter of 2.5 µm reduced epithelial mucous and epithelium thickness, while total suspended particles behaved similarly to the control group. Total suspended particles exhibited a predominance of Fe and no organic compounds, while the particulate matter 2.5 µm contained predominant amounts of S, Fe, Si and, to a lesser extent, Cu, Ni, V, Zn and organic compounds.CONCLUSION:Our results showed that different compositions of particles induced different airway epithelial responses, emphasizing that knowledge of their individual characteristics may help to establish policies aimed at controlling air pollution

Fatores que influenciam a escolha da área de atuação entre formandos em Terapia Ocupacional

The objectives of this study were to identify factors that influence the choice of professional acting area among Universidade Federal de Minas Gerais (UFMG) and Faculdade de Ciências Médicas de Minas Gerais (FCMMG) Occupational Therapy undergraduate students; to characterize the relevance of these factors in the choice of professional interest area and to compare specific choosing factors among the undergraduate students from both distinct (public and private schools) Occupational Therapy courses in the city of Belo Horizonte/MG. Surveying forms were distributed to all UFMG students graduating in the second semester of 2001, first and second semesters of 2002, and to the FCMMG graduating classes of 2001 and 2002. The data were analyzed with quantitative procedures by means of their statistical frequency. The results revealed the following factors as relevant, which were ranked higher (above 7 in 10) in their process of decision: fondness, vocation, readiness, relationship with professionals, curricular practical experience, faculty educational background, professor/student relationship, and area theoretical/clinical consistency.

Conversion from immediate-release tacrolimus to prolonged-release tacrolimus in stable heart transplant patients: a retrospective study

[Abstract] Background Lifelong adherence with post-transplant immunosuppression is challenging, with nonadherence associated with greater acute rejection (AR) risk. Methods This retrospective study evaluated conversion from immediate-release tacrolimus (IRT) to prolonged-release tacrolimus (PRT), between January 2008 and December 2012 in stable adult heart transplant recipients. Cumulative incidence rate (IR) of AR and infection pre- and postconversion, safety, tacrolimus dose and trough levels, concomitant immunosuppression, and PRT discontinuation were analyzed (intention-to-treat population). Results Overall, 467 patients (mean age, 59.3 [SD, 13.3] years) converted to PRT at 5.1 (SD, 4.9) years post transplant and were followed for 3.4 (SD, 1.5) years. During the 6 months post conversion, 5 patients (1.1%; 95% CI, 0.35%–2.48%) had an AR episode and IR was 2.2/100 patient-years (95% CI, 0.91–5.26). Incidence of rejection preconversion varied by time from transplant to conversion. Infection IR was similar post- and preconversion (9.2/100 patient-years [95% CI, 7.4–11.3] vs 10.6/100 patient-years [95% CI, 8.8–12.3], respectively; P = .20). Safety variables remained similar post conversion. The IR of mortality/graft loss was 2.3/100 patient-years (95% CI, 1.7–3.1). Conclusions Conversion from IRT to PRT in heart transplant recipients in Spain was associated with no new safety concerns and appropriate immunosuppressive effectiveness
