    Esta investigación tiene la intención de ofrecer orientaciones a la comunidad educativa y de esta forma, se conforme en una guía de trabajo que contemple los aspectos instruccionales para agilizar el diseño y desarrollo de cursos virtuales, así como el establecimiento de la fundamentación teórica para la propuesta ante la institución educativa donde se desarrolla el proyecto. Es así que se formuló la siguiente pregunta de investigación: ¿De qué manera la implementación de un diseño instruccional sustentado en el modelo ADDIE (Análisis, Diseño, Desarrollo, Implementación y Evaluación) coadyuva con el aprendizaje del diseño de páginas web de la facultad de Ingeniería de Sistemas en una institución de educación superior de Colombia? Se contempló una revisión del enfoque de estudio de casos bajo la propuesta de Stake (2007), en donde se manifiesta la importancia de estudiar a profundidad un caso específico de forma individual antes que por un método de investigación. Se seleccionó una muestra por conveniencia de 3 docentes y 30 estudiantes a quienes se les aplico entrevista semi-estructurada como fuente primaria de recolección de información y la observación no participante y registro anecdótico. Entre los principales hallazgos se encuentra: Los estudiantes de modo contundente hacen comunión total al manifestar que reconocen los contenidos y competencias a desarrollar en el curso. Los docentes a su vez coinciden al manifestar que planear y diseñar las unidades didácticas son herramienta base para proyectar el éxito en el alcance de los objetivos propuestos y reconocen la importancia de la implementación del diseño instruccional y su aplicación en el desarrollo del acto pedagógico, para lograr los objetivos del curso.Instituto Tecnológico de Estudios Superiores de Monterrey ITESMCapítulo 1.

    Many studies had described the morbi-mortality related to medicines. As for the strategies to reduce the possible risks for medicine therapy is very important to readvise the pharmaceutical activity, once the pharmacist has potential for constitute an essential part for the solution of problems related to the utilization of medicines. The purpose of this work was to demonstrate that the therapeutic subdosage and the microbiological contamination may be directly involved with the inappropriate manipulation of medicines stored in residences. Liquid dosage forms containing dipyrone market in Brazil and stored at homes in Araraquara (SP) were analyzed regarding quantitative and microbiological analysis. Only in 57% from 128 samples analyzed the drug quantity was in accordance. Moreover, 26.2% from 128 samples analyzed presented S. aureus, E. coli and Salmonella sp. These results demonstrated clear reduction in their quality, as well as the presence of molds and/or bacteria in some medicines that still agreed with the expirations dates, showing the importance of the pharmacist in advising the correct use and store of medicines.Vários estudos relatam a ocorrência de morbi-mortalidade relacionada com medicamentos. Quanto às estratégias para reduzir possíveis riscos à terapia medicamentosa é de suma importância a necessidade de reorientação da atividade farmacêutica, uma vez que o profissional farmacêutico tem potencial para se constituir em uma parte essencial para a solução dos problemas relacionados à utilização de medicamentos. O objetivo deste trabalho foi demonstrar que o fator subdosagem terapêutica e a contaminação microbiana podem estar diretamente envolvidos com a manipulação inadequada dos medicamentos mantidos nas residências. Medicamentos líquidos contendo dipirona comercializados no Brasil e armazenados em residências em Araraquara (SP) foram avaliados no que se refere a análises quantitativa e microbiológica. Somente em 57% das 128 amostras analisadas a quantidade de fármaco estava de acordo. Além disso, 26,2% das 128 amostras analisadas apresentaram S. aureus, E. coli e Salmonella sp. Esses resultados demonstraram clara queda na qualidade dos mesmos, assim como a presença de fungos e/ou bactérias em alguns dos medicamentos, que ainda estavam dentro de seus prazos de validade, demonstrando a importância do profissional farmacêutico na orientação quanto ao uso e ao armazenamento correto do medicamento

    Limited data on the coagulation profile in children affected by the SARS-CoV-2 infection are available. We aimed to evaluate the role of d-dimers as predictors of poor outcomes in a pediatric population affected by the SARS-CoV-2 infection or multisystem inflammatory syndrome (MIS-C). We performed a retrospective cross-sectional multicenter study. Data from four different centers were collected. Laboratory tests, when performed, were collected at the time of diagnosis, and 24, 48, 72, 96, 120 and beyond 120 h from diagnosis; blood counts with formula, an international normalized ratio (INR), activated partial thromboplastin time (aPTT), D-dimers and fibrinogen values were collected. Data regarding clinical history, management and outcome of the patients were also collected. Three hundred sixteen patients with a median age of 3.93 years (IQR 0.62–10.7) diagnosed with COVID-19 or MIS-C were enrolled. Fifty-eight patients (18.3%) showed a severe clinical outcome, 13 (4.1%) developed sequelae and 3 (0.9%) died. The univariate analysis showed that age, high D-dimer values, hyperfibrinogenemia, INR and aPTT elongation, and low platelet count were associated with an increased risk of pediatric intensive care unit (PICU) admission (p < 0.01). Three multivariate logistic regressions showed that a d-dimer level increase was associated with a higher risk of PICU admission. This study shows that D-dimer values play an important role in predicting the more severe spectrum of the SARS-CoV-2 infection, and was higher also in those that developed sequelae, including long COVID-19

    Induction of apoptosis in A549 pulmonary cells by two Paracoccidioides brasiliensis samples

    Paracoccidioidomycosis presents a variety of clinical manifestations and Paracoccidioides brasiliensis can reach many tissues, most importantly the lungs. The ability of the pathogen to interact with host surface structures is essential to its virulence. The interaction between P. brasiliensis and epithelial cells has been studied, with particular emphasis on the induction of apoptosis. To investigate the expression of different apoptosis-inducing pathways in human A549 cells, we infected these cells with P. brasiliensis Pb18SP (subcultured) and 18R (recently isolated from cell culture and showing a high adhesion pattern) samples in vitro. The expressions of Bcl-2, Bak and caspase 3 were analysed by flow cytometry and DNA fragmentation using the TUNEL technique. Apoptosis of human A549 cells was induced by P. brasiliensis in a sample and time-dependent manner. Using an in vitro model, our data demonstrates that caspase 3, Bak, Bcl-2 and DNA fragmentation mediate P. brasiliensis-induced apoptosis in A549 cells. The overall mechanism is a complex process, which may involve several signal transduction pathways. These findings could partially explain the efficient behaviour of this fungus in promoting tissue infection and/or blood dissemination.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

    Genomic surveillance of SARS-CoV-2 in patients presenting neurological manifestations

    Get PDF
    During the first wave of infections, neurological symptoms in Coronavirus Disease 2019 (COVID-19) patients raised particular concern, suggesting that, in a subset of patients, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could invade and damage cells of the central nervous system (CNS). Indeed, up to date several in vitro and in vivo studies have shown the ability of SARS-CoV-2 to reach the CNS. Both viral and/or host related features could explain why this occurs only in certain individuals and not in all the infected population. The aim of the present study was to evaluate if onset of neurological manifestations in COVID-19 patients was related to specific viral genomic signatures. To this end, viral genome was extracted directly from nasopharyngeal swabs of selected SARS-CoV-2 positive patients presenting a spectrum of neurological symptoms related to COVID-19, ranging from anosmia/ageusia to more severe symptoms. By adopting a whole genome sequences approach, here we describe a panel of known as well as unknown mutations detected in the analyzed SARS-CoV-2 genomes. While some of the found mutations were already associated with an improved viral fitness, no common signatures were detected when comparing viral sequences belonging to specific groups of patients. In conclusion, our data support the notion that COVID-19 neurological manifestations are mainly linked to patient-specific features more than to virus genomic peculiarities
