Orthodontic brackets friction changes after clinical use : a systematic review
2019
Background To evaluate the bracket-wire friction force after clinical use. Material and methods A systematic search of several electronic databases (PubMed, Embase, Web of Science, Scopus, The Cochrane Library, Lilacs and Google Scholar) without limitations regarding publication year or language, was performed. In-vitro studies analyzing the changes in friction force of orthodontic brackets before/after their clinical use were considered. Risk of Bias was assessed with Downs and Black checklist. All methodological features that could interfere in the results were specifically described. Results Seven studies satisfied the inclusion criteria and were included in the review. All 7 studies rep…
HAV infection in chronic liver disease: a rationale for vaccination.
2003
We report the conduct and results of a systematic search of the literature to assess whether exposure to HAV could induce a fatal deterioration of liver diseases. We assessed 30 studies and found evidence of progressive decrease of natural immunity against HAV in Italy. HAV vaccine seems as safe in chronic liver diseases than in general population. On the basis of the evidence we recommend that subjects with chronic liver disease should be vaccinated against HAV, especially if younger than 40 years.
On the origin of the X-ray emission from Herbig Ae/Be stars
2006
We performed a systematic search for Chandra archival observations of Herbig Ae/Be stars. These stars are fully radiative and not expected to support dynamo action analogous to their convective lower-mass counterparts, the T Tauri stars. Their X-ray emission has remained unexplained. The superior spatial resolution of Chandra with respect to previous X-ray instrumentation has allowed us to examine the possible role of late-type companions in generating the observed X-rays. In the total sample of 17 Herbig Ae/Be stars, 8 are resolved from X-ray emitting faint companions or other unrelated X-ray bright objects within 10". The detection fraction of Herbig Ae/Be stars is 76 %, but lowers to 35 …
Asthma diagnosis in infants and preschool children: a systematic review of clinical guidelines.
2019
Background and aim: The definition and diagnosis of asthma are the subject of controversy that is particularly intense in the case of individuals in the first years of life, due to reasons such as the difficulty of performing objective pulmonary function tests or the high frequency with which the symptoms subside in the course of childhood. Since there is no consensus regarding the diagnosis of asthma in preschool children, a systematic review has been carried out. Materials and methods: A systematic search was made of the clinical guidelines published in the last 10 years and containing information referred to the concept or diagnosis of asthma in childhood - including the first years of l…
Diabetes mellitus tipo 1: breve revisión de los principales factores psicológicos asociados
2015
Resumen: La diabetes mellitus tipo 1 (DM1) es una enfermedad crónica ampliamente extendida entre la población infantojuvenil. Suele suponer una sobrecarga significativa en el niño y su familia, modificando aspectos en su estilo de vida, necesarios para cumplimentar las exigencias del tratamiento.Nuestro objetivo es estudiar las principales características psicológicas, familiares y de ajuste a la enfermedad de los niños y adolescentes diagnosticados de DM1, haciendo especial hincapié en los factores psicopatológicos asociados.La metodología empleada ha consistido en una búsqueda bibliográfica sistemática en las principales bases de datos científicas.Debido al impacto biopsicosocial que la D…
El currículum oculto visual en los libros de texto de Educación Física: Una revisión sistemática
2021
RESUMEN: El presente estudio tiene como objetivo principal revisar las diferentes investigaciones relacionadas con el análisis de las imágenes de los libros de texto de Educación Física (EF) en la enseñanza obligatoria del sistema educativo español, en el período que comprende las leyes educativas de la Ley Orgánica 1/1990 de Ordenación General del Sistema Educativo (LOGSE), la Ley Orgánica 2/2006 de Educación (LOE) y la Ley Orgánica 8/2013 para la Mejora de la Calidad Educativa (LOMCE). Para ello se realizó una búsqueda sistemática siguiendo las pautas de PRISMA en las bases de datos de Dialnet, Google Scholar, Redalyc, Scielo, Scopus y Web of Science, seleccionando 20 artículos de 253 enc…
Serotypes of Aggregatibacter actinomycetemcomitans in relation to periodontal status and geographic origin of individuals-a review of the literature
2014
Objectives: Several studies have focused on the relationship among serotype distribution, ethnical status and geo - graphic populations, and periodontal conditions. Studies that have investigated the prevalence and the distribution of A. actinomycetemcomitans serotypes and the relation between the different serotypes of the bacterium and periodontal status were reviewed. Material and Methods: A systematic literature search for publications regarding the distribution of A. actinomyc - etemcomitans serotypes in subgingival samples of periodontitis patients and periodontally healthy subjects by employing polymerase chain reaction (PCR) was conducted. Results: From the 85 studies identified in …
Use of simulation-based learning among perioperative nurses and students: A scoping review.
2018
Abstract Objectives Simulation-based learning has been extensively explored, especially in baccalaureate nursing programmes. Recently, simulation-based learning has been introduced in perioperative nursing. The aim of this scoping review is to investigate work published on the use of simulation-based learning in the field of perioperative nursing. Design and data sources A scoping review was conducted using the methodological framework of Arksey and O'Malley to identify a broad range of relevant literature, regardless of study design. A comprehensive and systematic search was performed using Medline, CINAHL, Eric, Svemed+, PsychINFO and Embase in May 2016 and then was updated in February 20…
Decoupling Office Energy Efficiency From Employees' Well-Being and Performance: A Systematic Review
2019
Energy efficiency (i.e., the ratio of output of performance to input of energy) in office buildings can reduce energy costs and CO2 emissions, but there are barriers to widespread adoption of energy efficient solutions in offices because they are often perceived as a potential threat to perceived comfort, well-being, and performance of office users. However, the links between offices' energy efficiency and users' performance and well-being through their moderators are neither necessary nor empirically confirmed. The purpose of this study is to carry out a systematic review to identify the existing empirical evidence regarding the relationships between energy-efficient solutions in sustainab…

2018
Background Three-dimensional view in laparoscopic general, gynaecologic and urologic surgery is an efficient, safe and sustainable innovation. The present paper is an extract taken from a full health technology assessment report on three-dimensional vision technology compared with standard two-dimensional laparoscopic systems. Methods A health technology assessment approach was implemented in order to investigate all the economic, social, ethical and organisational implications related to the adoption of the innovative three-dimensional view. With the support of a multi-disciplinary team, composed of eight experts working in Italian hospitals and Universities, qualitative and quantitative d…
