Teorias de aprendizagem e suas contribuições no contexto escolar: um diálogo entre os principais teóricos e a contemporaneidade – Uma revisão Narrativa / Learning theories and their contributions in the school context: a dialogue between the main theorists and contemporaneity - A Narrative review

Este artigo tem como objetivo apresentar as teorias de aprendizagem defendidas pelos teóricos Piaget, Vygotsky, Bruner, Ausubel e Gardner e as principais contribuições de cada um para o campo educacional. Estas teorias têm contribuído para ter-se uma compreensão dos processos de aprendizagem visando oferecer avanços de qualidade para o ensino, pois tem subsidiado os docentes na sua prática diária. Apresentamos um esboço das ideias básicas dos teóricos supracitados que discorrem sobre suas teorias de como a aprendizagem acontece e realizamos um paralelo da aplicabilidade no contexto contemporâneo da educação escolar. Conclui-se que quando se faz referência ao processo de ensino-aprendizagem é necessária uma compreensão bem mais ampla a respeito desse processo, pois ensinar vai além do espaço da sala de aula e das atividades executadas pelos estudantes. O docente precisa ter ciência das teorias de aprendizagens, a fim de usá-la a seu favor para favorecer o aprendizado dos alunos, bem como planejar suas aulas evitando improvisos e dessa forma, empenha-se em promover as transformações sociais

Efficacy of bacterial cellulose membrane for the treatment of lower limbs chronic varicose ulcers: a randomized and controlled trial

ABSTRACT Objective: to evaluate the efficacy of Bacterial Cellulose (BC) membrane dressings in the treatment of lower limb venous ulcers. Methods: we carried out a prospective, randomized, controlled study of 25 patients with chronic venous ulcer disease in the lower limbs from the Angiology and Vascular Surgery Service of the Federal University of Pernambuco Hospital and from the Salgado Polyclinic of the County Health Department, Caruaru, Pernambuco. We randomly assigned patients to two groups: control group, receiving dressings with triglyceride oil (11 patients) and experimental group, treated with BC membrane (14 patients). We followed the patients for a period of 120 days. Results: There was a reduction in the wound area in both groups. There were no infections or reactions to the product in any of the groups. Patients in the BC group showed decreased pain and earlier discontinuation of analgesic use. Conclusion: BC membrane can be used as a dressing for the treatment of varicose ulcers of the lower limbs

DIVERTICULITE COMPLICADA (HINCHEY 1B)

<p>Através da camada muscular do cólon, que os divertículos colônicos são herniações não complicadas da mucosa e da submucosa colônica. Quando com o tempo ocorrem essas modificações são definidos falsos divertículos ou pseudodivertículos, já que não envolvem todas as camadas da parede dos cólons, pois se envolvessem, seriam chamados de divertículos verdadeiros (KOHL <i>et al.</i>, 2018).</p&gt

Projetos de Letramento no Ensino Médio: novas perspectivas e desafios

Resumo: Este artigo discute as implicações das novas perspectivas do ensino e aprendizagem de língua materna, em especial o trabalho centrado em projetos que tomam a prática social e as demandas dos sujeitos como ponto de partida para as ações metodológicas, e se volta para a análise de um projeto de letramento realizado no Programa Institucional de Bolsa de Iniciação à Docência (PIBID) do curso de Letras Português da UFSC, que se deu por meio de uma pesquisa-ação (Thiollent, 2008) em uma turma de terceiro ano do Ensino Médio de uma escola pública. As conclusões levam a crer que a falta de engajamento dos alunos pode ter se dado em função da distinção entre práticas de letramento escolares e familiares, demandando ressignificações metodológicas na formulação de projetos de letramento

ABC-SPH risk score for in-hospital mortality in COVID-19 patients : development, external validation and comparison with other available scores

The majority of available scores to assess mortality risk of coronavirus disease 2019 (COVID-19) patients in the emergency department have high risk of bias. Therefore, this cohort aimed to develop and validate a score at hospital admission for predicting in-hospital mortality in COVID-19 patients and to compare this score with other existing ones. Consecutive patients (≥ 18 years) with confirmed COVID-19 admitted to the participating hospitals were included. Logistic regression analysis was performed to develop a prediction model for in-hospital mortality, based on the 3978 patients admitted between March-July, 2020. The model was validated in the 1054 patients admitted during August-September, as well as in an external cohort of 474 Spanish patients. Median (25-75th percentile) age of the model-derivation cohort was 60 (48-72) years, and in-hospital mortality was 20.3%. The validation cohorts had similar age distribution and in-hospital mortality. Seven significant variables were included in the risk score: age, blood urea nitrogen, number of comorbidities, C-reactive protein, SpO/FiO ratio, platelet count, and heart rate. The model had high discriminatory value (AUROC 0.844, 95% CI 0.829-0.859), which was confirmed in the Brazilian (0.859 [95% CI 0.833-0.885]) and Spanish (0.894 [95% CI 0.870-0.919]) validation cohorts, and displayed better discrimination ability than other existing scores. It is implemented in a freely available online risk calculator (https://abc2sph.com/). An easy-to-use rapid scoring system based on characteristics of COVID-19 patients commonly available at hospital presentation was designed and validated for early stratification of in-hospital mortality risk of patients with COVID-19
