Level of Physical Activity and In-Hospital Course of Patients with Acute Coronary Syndrome

Abstract Background: Acute coronary syndrome (ACS) is one of the main causes of morbidity and mortality in the modern world. A sedentary lifestyle, present in 85% of the Brazilian population, is considered a risk factor for the development of coronary artery disease. However, the correlation of a sedentary lifestyle with cardiovascular events (CVE) during hospitalization for ACS is not well established. Objective: To evaluate the association between physical activity level, assessed with the International Physical Activity Questionnaire (IPAQ), with in-hospital prognosis in patients with ACS. Methods: Observational, cross-sectional, and analytical study with 215 subjects with a diagnosis of ACS consecutively admitted to a referral hospital for cardiac patients between July 2009 and February 2011. All volunteers answered the short version of the IPAQ and were observed for the occurrence of CVE during hospitalization with a standardized assessment conducted by the researcher and corroborated by data from medical records. Results: The patients were admitted with diagnoses of unstable angina (34.4%), acute myocardial infarction (AMI) without ST elevation (41.4%), and AMI with ST elevation (24.2%). According to the level of physical activity, the patients were classified as non-active (56.3%) and active (43.7%). A CVE occurred in 35.3% of the cohort. The occurrence of in-hospital complications was associated with the length of hospital stay (odds ratio [OR] = 1.15) and physical inactivity (OR = 2.54), and was independent of age, systolic blood pressure, and prior congestive heart failure. Conclusion: A physically active lifestyle reduces the risk of CVE during hospitalization in patients with ACS.

Mapping of the healthy immunoglobulin repertoire over the course of B cell maturation by deep pyrosequencing

Healthy immunoglobulin repertoire has not been extensively evaluated reflecting in part the challenge of generating sufficiently robust data sets by conventional clonal sequencing. Deep sequencing has revolutionized the capacity to evaluate the depth and breadth of the Ig repertoire along the B cell developmental pathway, and can be used to pin point defect(s) of primary or acquired B-cell associated diseases. In this study healthy IgM and IgG repertoires were studied by 454-pyrosequencing to establish the healthy controls for diseased repertoires. (...)

L' Ensenyament per tasques: programació d'una assignatura de traducció de l'alemany a l'espanyol

In this work we present a proposal for a course in translation from German into Spanish following the task based approach as known in second language acquisition. The aim is to improve the translation competence of translation students. We depart from the hypothesis that some students select inapropiate translation strategies when faced with certain translation problems leading them to translation errors. In order to avoid these translation errors originated by wrong application of such strategies we propose a didactic method which helps to prevent them by a) raising awareness of the different subcompetences required while translating, b) improving the ability to identify translation problems and relate them to the different subcompetences and c) enhancing the use of the most adequate strategy according to the characteristics of each problem. With regard to translation and how translation competence is acquired our work follows the communicative approach to translation theory as defended among others by Hatim & Mason (1990), Lörscher (1992) and Kiraly (1995), where translation is seen as a communicative activity which can be analized from a psycholinguistic perspective. In this sense we give operative definitions for what we understand by “translation problem”, “translation strategy”, “translation error”, “translation competence” and “translation”. Our approach to didactics adapts recent developments in Second Language Teaching within the communicative paradigm as is the task based approach by Nunan (1989) acquisition to translation. Fitting the recquirements of this pedagogic approach we present a planning for a translation course which is compatible with present translation studies.

Sistema de comunicació sense fils utilitzant Zigbee per PDA

La implementació consta d’un driver SDIO per Windows CE 4.2, el controlador SDIO a la FPGA i l'enllaç de comunicació entre la FPGA i el microcontrolador.

Studies on Trypanosoma rangeli Tejera, 1920: IX. Course of infection in different stages of Rhodnius prolixus

Frequent individual observations od different stages of Rhodnius prolixus exposed to Trypanosoma rangeli, revealed a higher susceptibility to infection in the bugs exposed during the two first instars. The mortality rate in infected bugs was significantly higher than in controls, indicating that the parasite was responsible for the majority of deaths. An analysis of the mortality distribution, per instar, is presented. Statistical analysis of deaths among the different infected instars, showed that T. rangeli produces its pathological effect in any stage of R. prolixus independently of its susceptibility to the parasite. The survival to adult decreased in all the infected instar bugs. A significant longer time to reach the adult stage was observed in the infected bugs when compared with controls, excepting for specimens exposed in the third instar. The epidemiological significance of the present results is discussed.

Substance use and depression. Comparative course in adolescents.

OBJECTIVE: To examine the relation between depression and substance use in adolescents and the concomitant courses of both disorders. METHODS: Four individual interviews were administered to 85 adolescent substance users aged 14-19 years (mean 17.1 years, SD 1.4) over a 3.5 year period using the Adolescent Drug Abuse Interview (ADAD) and the Beck Depression Inventory (BDI-13). RESULTS: No predictive effect was observed on one dimension over the other, but each dimension was predictive of its own course. A decrease in substance-use severity paralleled a decrease in depressive state. Similarly, stable substance-use rates, either at a low or a high level, tended to be associated with low or high levels of depression, respectively. However, an increase in substance use was not accompanied by an increase in depressive states. Moreover, depression varied greatly between adolescents, and according to gender and age. CONCLUSIONS: Depressive states and substance use in adolescents can vary considerably overtime, and are closely but rather synchronically related. Since most of the adolescents do not seek help for substance-related problems, substance use should be systematically assessed in adolescents presenting with a depressive state.

Levels of lethal antibody during the course of infection with Schistosoma mansoni in rats and mice

Schistosoma mansoni infected hosts produce an IgG that mediates the complement-dependent killing of schistosomula in vitro. In this study, we followed the levels of serum lethal antibody during infection of rats and mice. Rats presented detectable lethal activity early in the course of infection with a peak in the 6-8th week of infection. This activity declined to non-detectable levels within 2 weeks, remaining low up to the 20-26th week. In mice, lethal antibody was not detected before 7-12 weeks of infection, but raised to higher levels, as compared to non-infected animals, up to 20-24 weeks after infection. We correlate lethal antibody and protective immunity suggesting that the antibody-mediated complement-dependent cytotoxicity to schistosomula play a role in the immunity to reinfection.
