Information Technology (IT) can be an important component for innovation since enabling e-learning it can provide conditions to which the organization can work with new business and improved processes. In this regard, the Learning Management Systems (LMS) allows communication and interaction between teachers and students in virtual spaces. However the literature indicates that there are gaps in the researches, especially concerning the use of IT for the management of e-learning. The purpose of this paper is to analyze the available literature about the application of LMS for the e-learning management, seeking to present possibilities for researches in the field. An integrative literature review was performed considering the Web of Science, Scopus, Ebsco and Scielo databases, where 78 references were found, of which 25 were full papers. This analysis derives interesting characteristics from scientific studies, highlighting gaps and guidelines for future research.

High quality, well designed medical devices are necessary to provide safe and effective clinical care for patients as well as to ensure the health and safety of professional and lay device users. Capturing the user requirements of users and incorporating these into design is an essential component of this. The field of ergonomics has an opportunity to assist, not only with this area, but also to encourage a more general consideration of the user during medical device development. A review of the literature on methods for assessing user requirements in engineering and ergonomics found that little published work exists on the ergonomics aspects of medical device development. In particular there is little advice available to developers on which issues to consider during design and development or recommendations for good practice in terms of the methods and approaches needed to capture the full range of user requirements. The Multidisciplinary Assessment of Technology Centre for Healthcare (MATCH) is a research collaboration that is working in conjunction with industrial collaborators to apply ergonomics methods to real case study projects with the ultimate aim of producing an industry-focused guide to applying ergonomics principles in medical device development.

Introducción: La diverticulosis es la condición más frecuentemente encontrada en la colonoscopia, condición asintomática, con un alto costo para el sistema de salud. Diversos factores han demostrado estar en relación con la aparición de la enfermedad. En nuestra población, esta información se desconoce; el objetivo del estudio es la caracterización de la población con diverticulosis y su relación con la frecuencia de la ingesta de fibra. Materiales y Métodos: Estudio observacional prospectivo de corte transversal con componente analítico. Realizado a todas las personas que asistieron al HUS a realización de colonoscopia entre Noviembre de 2015 y Abril de 2016. Se recolectaron datos de la frecuencia de fibra ingerida a través de entrevistas basadas. Resultados: Se estudiaron 278 personas, 55.7% mujeres. La prevalencia de diverticulosis fue de 21.58%, siendo más frecuente en mujeres ( 66,7%), 31% entre los 71-80 años, 2,16% tenían antecedente familiar de diverticulosis; principal sitio de afectación fue colon sigmoide en las mujeres y el colon descendente en los hombres. En las personas con diverticulosis el consumo de harina de trigo fue mayor (91,67% vs 86,7%), mientras el consumo de frutas fue mayor en las personas que no presentaron diverticulosis (83,49% vs 78,33%). Conclusiones: La prevalencia de diverticulosis es similar a lo reportado en la literatura. Así mismo se encontró un mayor consumo de fibra en la población sin divertículos lo que hace pensar que a pesar de que esta condición es multifactorial , el consumo de mayores cantidades de fibra puede prevenir la aparición de la misma

O presente relatório está inserido no âmbito da unidade curricular do Estágio Curricular do Mestrado Integrado em Medicina Veterinária da Universidade de Évora, sob orientação da Drª Sónia Lucena e coorientação da Drª Ângela Martins. Encontra-se dividido em duas partes, a primeira é referente à casuística acompanhada no Hospital Veterinário da Arrábida e Centro de Reabilitação Animal da Arrábida durante o período de cinco meses de estágio. Na casuística são expostos de forma breve os casos clínicos e procedimentos acompanhados durante o período de estágio. Na segunda parte é desenvolvida uma monografia intitulada “Maneio da dor crónica” acompanhada por uma descrição de um caso clínico assistido durante o estágio. A dor crónica é considerada uma dor patológica, deixando de ser um mecanismo de defesa do organismo e passando a ser considerada uma doença. É de difícil tratamento e requer um esforço multidisciplinar; ABSTRACT: Small Animal Medicine This report is conducted under the context of the curricular internship course unit of integrated master’s degree in Veterinary Medicine at the University of Évora under the supervision of Dr. Sónia Lucena and cosupervision of Dr. Ângela Martins. The first component refers to the assisted cases followed in Hospital Veterinário da Arrábida and Centro de Reabilitação Animal da Arrábida during the five months of the practice period. In the followed cases part it is explored briefly some clinical cases and procedures accompanied during that practice period. The second component consists of a monograph titled “Chronic pain management” accompanied with a description of a clinical case followed seen during the practice period. Chronic pain is considered a pathological pain, ceasing to be a defense mechanism of the body and to be considered a disease. It is difficult to treat and requires a multidisciplinary effort.

Immune checkpoint inhibitors (ICI) that target PD-1/PD-L1 have recently emerged as an integral component of front-line treatment in metastatic NSCLC patients. The PD-1 inhibitor pembrolizumab is approved as monotherapy for advanced NSCLC with a PD-L1 tumor proportion score (TPS) of ≥1% and in combination with platinum doublet chemotherapy regardless of PD-L1 expression level. However, responses to either regimen occur in only a minority of cases, and PD-L1 TPS is limited as a biomarker in predicting whether a cancer will respond to PD-1 inhibition alone or would be more likely to benefit from PD-1 inhibition plus chemotherapy. Additional biomarkers of immunotherapy efficacy, such as tumor mutational burden (TMB), have not been incorporated into routine clinical practice for treatment selection. The identification of patients who have the greatest likelihood of responding to immunotherapies is critical for guiding treatment decisions. IN addition, early indicators of response could theoretically prevent patients from staying on an ineffective therapy where they might experience complications due to disease progression or develop toxicities from unnecessary exposure to an inactive agent. The aim of this research project is to investigate the clinicopathologic and molecular determinant of response/resistance to the currently available immune checkpoint inhibitors, in order to identify therapeutic vulnerabilities that can be exploited to improve the clinical outcomes of patients with advanced NSCLC.

In long-term oral rehabilitation treatments, resistance of provisional crowns is a very important factor, especially in cases of an extensive edentulous distal space. The aim of this laboratorial study was to evaluate an acrylic resin cantilever-type prosthesis regarding the flexural strength of its in-balance portion as a function of its extension variation and reinforcement by two types of fibers (glass and polyaramid), considering that literature is not conclusive on this subject. Each specimen was composed by 3 total crowns at its mesial portion, each one attached to an implant component (abutment), while the distal portion (cantilever) had two crowns. Each specimen was constructed by injecting acrylic resin into a two-part silicone matrix placed on a metallic base. In each specimen, the crowns were fabricated with either acrylic resin (control group) or acrylic resin reinforced by glass (Fibrante, Angelus) or polyaramide (Kevlar 49, Du Pont) fibers. Compression load was applied on the cantilever, in a point located 7, 14 or 21 mm from the distal surface of the nearest crown with abutment, to simulate different extensions. The specimen was fixed on the metallic base and the force was applied until fracture in a universal test machine. Each one of the 9 sub-groups was composed by 10 specimens. Flexural strength means (in kgf) for the distances of 7, 14 and 21 mm were, respectively, 28.07, 8.27 and 6.39 for control group, 31.89, 9.18 and 5.16 for Kevlar 49 and 30.90, 9.31 and 6.86 for Fibrante. Data analysis ANOVA showed statistically significant difference (p<0.05) only regarding cantilever extension. Tukey's test detected significantly higher flexural strength for the 7 mm-distance, followed by 14 and 21 mm. Fracture was complete only on specimens of non-reinforced groups.

The dorsal raphe nucleus (DRN) is the origin of ascending serotonergic projections and is considered to be an important component of the brain circuit that mediates anxiety- and depression-related behaviors. A large fraction of DRN serotonin-positive neurons contain nitric oxide (NO). Disruption of NO-mediated neurotransmission in the DRN by NO synthase inhibitors produces anxiolytic- and antidepressant-like effects in rats and also induces nonspecific interference with locomotor activity. We investigated the involvement of the 5-HT1A autoreceptor in the locomotor effects induced by NO in the DRN of male Wistar rats (280-310 g, N = 9-10 per group). The NO donor 3-morpholinosylnomine hydrochloride (SIN-1, 150, and 300 nmol) and the NO scavenger S-3-carboxy-4-hydroxyphenylglycine (carboxy-PTIO, 0.1-3.0 nmol) were injected into the DRN of rats immediately before they were exposed to the open field for 10 min. To evaluate the involvement of the 5-HT1A receptor and the N-methyl-D-aspartate (NMDA) glutamate receptor in the locomotor effects of NO, animals were pretreated with the 5-HT1A receptor agonist 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT, 8 nmol), the 5-HT1A receptor antagonist N-(2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl)-N-2-pyridinyl-cyclohexanecarboxamide maleate (WAY-100635, 0.37 nmol), and the NMDA receptor antagonist DL-2-amino-7-phosphonoheptanoic acid (AP7, 1 nmol), followed by microinjection of SIN-1 into the DRN. SIN-1 increased the distance traveled (mean ± SEM) in the open-field test (4431 ± 306.1 cm; F7,63 = 2.44, P = 0.028) and this effect was blocked by previous 8-OH-DPAT (2885 ± 490.4 cm) or AP7 (3335 ± 283.5 cm) administration (P < 0.05, Duncan test). These results indicate that 5-HT1A receptor activation and/or facilitation of glutamate neurotransmission can modulate the locomotor effects induced by NO in the DRN.

INTRODUÇÃO: em alguns casos, a extração de pré-molares torna-se necessária e nem sempre os espaços são completamente fechados após o alinhamento e nivelamento. O arco de dupla chave, ou Double Key Loop (DKL), é um arco retangular de aço para retração, com duas alças - uma mesial e outra distal ao canino. OBJETIVOS: este trabalho propôs-se a estudar o local onde a força é exercida, após a ativação desse arco, utilizando ativação na alça distal, ativação entre as alças e na alça distal, e ativação com Gurin®. MÉTODOS: foram montados nove modelos fotoelásticos de um arco dentário inferior, sem os primeiros pré-molares e os terceiros molares, com braquetes In-Ovation e arco DKL. O arco foi ativado e a região de incisivos, caninos e dentes posteriores foi fotografada, com interposição de filtros polarizadores de luz. RESULTADOS E CONCLUSÕES: após a análise do modelo fotoelástico, concluiu-se que a ativação com Gurin® pode produzir movimento de retração anterior com componente extrusivo; a ativação na alça distal pode produzir movimento de retração anterior sem componente extrusivo; e a ativação entre as alças e na alça distal pode produzir movimento de retração anterior com componente intrusivo.

OBJETIVO: Este estudo comparou parâmetros antropométricos e de resistência à insulina de indivíduos sem e com síndrome metabólica (SM), subestratificados pela presença de anormalidades glicêmicas. SUJEITOS E MÉTODOS: Foram incluídos 454 indivíduos (66% mulheres, 54% brancos), sendo 155 alocados para o grupo 1 (sem SM, sem anormalidade glicêmica), 32 para o grupo 2 (sem SM, com anormalidade glicêmica), 104 no grupo 3 (com SM, sem anormalidade glicêmica) e 163 no grupo 4 (com SM e anormalidade glicêmica). Os grupos foram comparados por ANOVA. RESULTADOS: Os grupos com SM (3 e 4) apresentaram os piores perfis antropométrico e lipídico; no grupo 2, apesar de glicemias significantemente mais elevadas, as médias das variáveis antropométricas e lipídicas não diferiram do grupo 1. Os maiores valores médios de HOMA-IR foram encontrados nos grupos com SM, enquanto o grupo 2 apresentou o menor HOMA-β. A trigliceridemia foi a variável metabólica com coeficientes de correlação mais elevados com a antropometria. Porém, as correlações mais fortes foram da circunferência da cintura (r = 0,503) e da razão cintura-altura (r = 0,513) com o HOMA-IR (p < 0,01). CONCLUSÃO: Nossos achados revelam que, em amostra da população brasileira, qualquer das medidas antropométricas identifica indivíduos com SM, mas não parece capaz de diferenciar aqueles com distúrbio glicêmico. Reforçamos a relação mais forte das medidas de adiposidade central com resistência à insulina, sugerindo utilidade da razão cintura-altura. É possível que componente autoimune contribua para o comprometimento do metabolismo glicídico dos indivíduos do grupo 2.
