Background: Road traffic accidents are potentially preventable multifactorial events due to factors such as vehicle fleet growth, human error and inadequate or insufficient laws, being responsible for a significant portion of morbidity and mortality in children. Objective: To calculate the Pediatric Trauma Score (PTS) and the Revised Trauma Score (RTS) and compare if there is a relationship between the severity of injury and the age of road traffic victims.

O estudo teve como objetivo avaliar as dificuldades dos enfermeiros de uma unidade de emergência no manejo do paciente politraumatizado. Trata-se de um estudo transversal, descritivo, de abordagem quantitativa, realizado com enfermeiros que atuam na emergência de um hospital público da região sudoeste do estado da Bahia, Brasil. Amostragem ocorreu de forma não probabilística, por conveniência, com amostra composta por 19 enfermeiros. Os dados foram analisados por estatística descritiva simples.

The aim of this study is to investigate the pedagogical practice of mathematics teachers from the final years of elementary school in the Municipal Public School of Teresina-PI, in effective teaching activity, based on the narratives of these teachers. This is an empirical research with a qualitative approach.

The objective of this study is to review and synthesize findings of the presence of comorbidities and mortality in the elderly after SARS-CoV infection. A systematic review and meta-analysis were conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive systematic search was performed on Pubmed and EMBASE, to find articles published until May 2020. For the prevalence estimates of the included observational studies, a random effects meta-analysis model was used with the Variance Estimator.

Our vision is to scale up this inspiring body of work to develop a collective approach to river rejuvenation that focuses on addressing the needs of the entire eco-system. A multi-stakeholder approach provides a practical framework to integrate all these different pockets of development into a larger picture for maximizing their impact.

Objective: To associate the levels of fatty acids in serum with anthropometric markers. Methods: A total of 48 subjects were evaluated by quantifying their relative percentages of serum free and esterified fatty acids (EFAs) by gas chromatography. Measures including body mass index (BMI), body fat percentage (BF%), waist circumference (WC) and waist-hip ratio (WHR) were used to characterize anthropometric measurements.

Esta pesquisa pretendeu aplicar uma nova metodologia de ensino com o estudo dos “mapas conceituais”, no qual esta ferramenta é capaz de organizar e mostrar o conhecimento de forma muito clara, além de demonstrar como as informações interagem.

This article describes the approach of the systems engineering to develop a Video Surveillance System. It used the concepts of integrated development and total vision framework as lines of direction for concept of the related system. The approach adopted the analysis of the interactions between product, process and organization during all the life cycle.

Defensins represent an important group of antimicrobial peptides and are expressed in the skin and other tissues of various mammalian species. These peptides participate in innate immunity, aiding in the immune response. The objective of this work was to compare the levels of β-defensin gene expressions (cBD1 and cBD103) in skin scrapings of the Poodle dogs with and without dermatitis. Eight dogs with dermatitis and 13 healthy dogs from the Veterinary Hospital and privately owned had collected skin scrapings. RNA extraction was obtained by Trizol® reagent.

A study was conducted to determine the effect of supplementing basal Rhodes grass hay with dried Calliandra leaves and common Vetch hay on growing dairy goats on voluntary feed intake and growth rate under a confined feeding system. A total of twelve weaned male Toggenburg crosses aged between 3 and 4 months were randomly allocated to 3 dietary treatments in a randomized complete block design. T1: Rhodes grass hay as the control, T2: 30% Calliandra + Basal diet, T3: 30% Vetch + Basal diet. The initial 10 days were allowed for adaptation to the diets and data collected for 8 weeks.
