CrossFit is training highly practiced by various athletes around the world, who prepare each year to be better and be selected to compete in the CrossFit Games. Currently very little known about the tests that assess muscle fatigue in athletes who practice this type of training. Muscle fatigue plays a fundamental role in the performance of athletes for their preparation and competition. The purpose of this study was to compare the different tests used to measure muscle fatigue in male CrossFit athletes. For them, a systematic search was carried out following the PRISMA guidelines, and the following inclusion criteria were included in the articles: original articles, CrossFit male athletes, and evaluation of muscle fatigue. Studies published in the last 10 years (from 2011 to March 31, 2021) the articles were not limited to a specific language, finding mostly English and Spanish. The main selection was by title, then by abstracting and reading the entire document in potential studies. Finally, five articles were found in which various tests were found to measure muscle fatigue in CrossFit athletes. In conclusion, given the wide variety of workouts (WOD) types of exercises and intensities in CrossFit, it is necessary to assess physical tests and biochemical markers.

The Subject

Pictorial symbols have multiple layers of meaning: not only do they represent objects, events and ideas about the world, they also represent the intentions of artists as well as other artist attributes (age, skill, originality and knowledge, mood, style and sentience). Although children’s developmental milestones of pictorial understanding have been the subject of a long-standing debate, their understanding of the relation between artists and pictures has often been neglected. The aim of this article was to conduct a systematic review on children’s and adolescents’ understanding of the relation between artists and pictures. PsycINFO and Web of Science databases were searched for English, Spanish, German, and Italian language empirical studies that examined this link in 2- to 18-year- olds. Forty-two citations (64 studies) from 14 different countries met the inclusion criteria. Results revealed the majority of the studies focused on the understanding of the artist’s intention. Although research on children’s and adolescents’ understanding of other attributes is scarce, and there were inconsistencies across the methodologies used, it seems that they first acknowledge intention and only later become more aware of how artist’s attributes are communicated through intention. The results of the review encourage subsequent research to provide a clearer conceptualised model of child and adolescent understanding of the artist-picture relationship. Such a model should be placed within a wider framework of the network of relationship between the artist, picture, world and beholder. Finally, consideration of how the development of understanding the artist-picture relationship is bi-directionally influenced with other developmental milestones in the child psychology is encouraged, particularly picture-production and theory of mind, and variations in atypical populations.

Abstract Background Opioids addiction and misuse are among the major problems in the world today. There have been several preliminary studies examining the effect of methadone on depression among addicts, however, these studies have reported inconsistent and even contradictory results. Therefore, the aim of the present study was to determine the effect of methadone on depression in addicts in Iran and around the world, using a meta-analysis approach. Methods This study was a systematic review and meta-analysis including articles published in the SID, MagIran, IranMedex, IranDoc, Cochrane, Embase, ScienceDirect, Scopus, PubMed and Web of Science databases were searched systematically to find articles published from 2006 to March 2019. Heterogeneity index was determined using the Cochran's test (Qc) and I2. Considering heterogeneity of studies, the random effects model was used to estimate the standardized difference of mean score for depression. Subsequently, the level of depression reduction in Iran and worldwide in the intervention group before and after the testwas measured. Results A total of 19 articles met the inclusion criteria, and were therefore selected for this systematic review and meta-analysis. The sample size of the intervention group in the selected studies was 1948. According to the meta-analysis results, the mean depression score in the intervention group was 26.4 ± 5.6 and 18.4 ± 2.6 before and after intervention respectively, indicating the reducing effect of methadone on depression, and this difference was statistically significant (P < 0.01). Conclusion The results of the present study show that methadone significantly reduces depression in addicts. Therefore, regular methadone use can be part of a drug treatment plan.

Background: Diabetes is referred to a group of diseases characterized by high glucose levels in blood. It is caused by a deficiency in the production or function of insulin or both, which can occur because of different reasons, resulting in protein and lipid metabolic disorders. The aim of this study was to systematically review the prevalence and incidence of type 1 diabetes in the world. Methods: A systematic search of resources was conducted to investigate the prevalence and incidence of type 1 diabetes in the world. The databases of Medline (via PubMed and Ovid),ProQuest, Scopus, and Web of Science from January 1980 to September 2019 were searched to locate English articles. The located articles were screened in multiple levels of title, abstract,and full-text and final studies that met the inclusion criteria were retrieved and included in the study. Results: From 1202 located articles, 193 studies were included in this systematic review. The results of meta-analysis showed that the incidence of type 1 diabetes was 15 per 100,000 people and the prevalence was 9.5% (95% CI: 0.07 to 0.12) in the world, which was statistically significant. Conclusion: According to the results, the incidence and prevalence of type 1 diabetes are increasing in the world. As a result, insulin will be difficult to access and afford, especially in underdeveloped and developing countries.

Educación Primaria

La capacidad aeróbica ha sido ampliamente estudiada a lo largo de los años, debido a su relación con la condición física, el rendimiento deportivo y la salud. Para la evaluación de la misma, un instrumento ampliamente utilizado es el test Course Navette, quecalcula de manera indirecta el consumo máximo de oxígeno. El objetivo de este estudio fue conocer el panorama actual del nivel de capacidad aeróbica en escolares de Educación Primaria, determinado a través del test Course Navette. Se realizó una revisión sistemática sobre estudios transversales llevados a cabo en todo el mundo, que evaluaron mediante el test Course Navette la capacidad aeróbica en escolares de Educación Primaria. En total, 19 estudios fueron incluidos en la revisión. La mayoría de los estudios muestran que los niños y niñas de primaria de diferentes países tienen una capacidad cardiorrespiratoria considerada como saludable. No obstante, las medias encontradas no son lo suficientemente eminentes, donde la volatilidad entre participantes resulta elevada. Por ello, es necesario mejorar los niveles de capacidad física en escolares, como un factor de importancia capital para el mantenimiento y optimización de la salud; especialmente, entre aquellos que se encuentran por debajo de los umbrales definidos para el riesgo cardiovascular. Aerobic capacity has been extensively studied over the years because of its relationship to fitness, sports performance, and health. For its evaluation, a widely used instrument is the Course Navette test, which indirectly calculates the maximum oxygen consumption. The objective of this study was to know the current panorama of the level of aerobic capacity in primary school children, determined through the Course Navette test. A systematic review was carried out on transversal studies carried out all over the world, which evaluated aerobic capacity in primary school children by means of the Course Navette test. A total of 19 studies were included in the review. Most studies show that primary school children in different countries have a cardiorespiratory capacity that is not considered a health risk. However, the averages found are not eminent enough, where volatility among participants is high. Therefore, it is necessary to improve the levels of physical capacity in schoolchildren, as a factor of capital importance for the maintenance and optimization of health, especially among those who are below the thresholds defined for cardiovascular risk.

Recreational Use

Marijuana is considered illicit in much of the world, and is classified as a drug for recreational use, in recent decades the medicinal use of Cannabis sativa L. has grown and diversified, being considered the only therapeutic alternative in the control of serious and incurable diseases such as syndrome of Dravet. The world panorama has shown a more liberal position, since in several countries such as the United States of America, Holland, Australia, Italy, and more recently in Canada, the use of medications, or even the recreational use of this plant, have been regulated. In this context, the investigation of the modifying effects on physical activity of empirically used cannabinoids is fundamental nowadays, mainly due to the regulatory recognition of Cannabis sativa L. as a medicinal plant in a large part of the world. Therefore, the objective of this review was to verify the evidence related to the effect of cannabis on physical performance and to identify and highlight the challenges in the interpretation of information regarding the performance of practitioners of physical activity, as well as athletes, presenting new trends in this area of research to be addressed. To carry out the systematic review, a bibliographic survey of case reports was obtained through Pubmed, Science Direct and Google Academic databases. The following keywords were used to perform the research: cannabis, performance, pain, competition. The following filters were used as inclusion criteria a languages used english; species: humans; types of articles: original articles and reviews and period of publication of articles: 1981 to 2021.

  El trabajo tiene por objetivo revisar la evidencia científica relacionada con el fútbol para personas amputadas. Para la búsqueda de referencia, se utilizó como descriptores las siguientes palabras clave: “Football” y “Amputee”. Los términos fueron introducidos en inglés en las siguientes bases de datos informatizadas: SPORTDiscus, PUBMED, Web Of Science y SCOPUS, considerando todos los documentos publicados hasta septiembre del 2020. Para limitar la búsqueda, se introdujeron cuatro criterios de inclusión: 1) Seleccionar documentos disponibles a texto completo o con resumen, 2) Contar con suficiente información relevante sobre el fútbol para personas con amputaciones (Mínimo 50 palabras), 3) Aportar información relacionada con la condición física, entrenamiento, lesiones y/o aspectos sociales de los jugadores de fútbol para personas con amputaciones, y 4) Estar escrito en español, inglés o portugués. La revisión sistemática exploratoria contó con diez documentos relacionados con el fútbol para personas con amputaciones. Los documentos existentes relacionados con la temática son escasos como consecuencia de la falta de evolución de esta modalidad. Estos manuscritos, en su mayoría, tratan aspectos como la fuerza y la resistencia. Además, un sólo documento habla de la utilización de dispositivos inerciales en sus mediciones. Por tanto, surge la necesidad de realizar nuevas investigaciones en el ámbito de fútbol para personas con amputaciones. Abstract. The study aims to review the scientific evidence related to football for amputees. For the reference search, the following keywords were used as descriptors: “Football” and “Amputee”. The terms were entered in English in the following computerized databases: SPORTDiscus, PUBMED, Web of Science and SCOPUS, considering all the documents published up to September 2020. To limit the search, four inclusion criteria were introduced: 1) Select documents available in full text or with abstract, 2) Have enough relevant information about soccer for amputees (Minimum 50 words), 3) Provide information related to the physical condition, training, injuries and / or social aspects of the players of soccer for people with amputations, and 4) Be written in Spanish, English or Portuguese. The exploratory systematic review featured ten football related documents for amputees. The existing documents related to the subject are scarce as a consequence of the lack of evolution of this modality. These manuscripts, for the most part, deal with aspects such as strength and endurance. Furthermore, only one document talks about the use of inertial devices in their measurements. Therefore, there is a need for further research in the field of football for amputees.

The article observes the current changes of the refugee crisis after the effect of COVID 19 that can lead to a growing crisis of more than 79.5 million refugee and displaced people across the world. The study aims to examine the prevailing and forthcoming challenges of refugees and displaced people. A systematic review was followed to conduct the study and articles were selected based on their inclusion criteria. There is a growing need to understand the refugee crisis coupled with the necessity to design practical resolutions. The study found institutional and financial support are the main drivers for the refugee management in their distress voyage. These are challenged due to the adverse effect of the COVID 19 epidemic and the current downturn of the world economy. The study tries to stress the array of institutions that are working on the support for the refugees and displaced people that are challenging and can result in a crisis in the future. The paper concludes with an argument about the changing scenario of policies for migration which are restricting and changing due to the existing pandemic which demands synergistic performance within the government to manage the crisis.

ABSTRACTObjectives: to realize a literature systematic review on the incidence of cancer in the world. Methodology: it was conducted a search in the database of the PUBMED with the descriptors epidemiology, prostate, cancer. We selected articles published from 2002 to 2007. It was used as a criterion for exclusion searches that are not directly addressing the incidence of prostate cancer in the population. They were collected the following variables: author(s), year, purpose, methodology and conclusions. Results: 10 articles were reported. Conclusions: it was possible to verify that in the world, the distribution of prostate cancer varies with ethnicity, genetic susceptibility and environmental factors such as diet. With regard to ethnicity, black men have greater susceptibility to tumor that white men of similar age. In the case of genetic, changes in alleles of genes that control the metabolism of androgens influence the incidence of tumor. As for nutrition, research confirms the influence of foods such as meat, fats and oils, ice cream, margarine and vegetable fat. Descriptors: neoplasms; prostate; epidemiology.RESUMO                                                                                                                                                    Objetivo: realizar revisão sistemática de literatura sobre a incidência dessa neoplasia no mundo. Metodologia: foi realizada busca na base de dados do PUBMED com os descritores epidemiology, prostate, câncer. Foram selecionados artigos publicados entre 2002 a 2007. Utilizou-se como critério de exclusão, pesquisas que não se tratavam diretamente da incidência do câncer de próstata na população. Foram coletadas as seguintes variáveis: autor(es), ano, objetivo, metodologia e conclusões. Resultados: foram relatados 10 artigos. Conclusões: foi possível verificar que, no mundo, a distribuição do câncer de próstata varia com a etnia, susceptibilidade genética e fatores ambientais, tais como dieta. Com relação à etnia pode-se perceber que homens negros possuem maior susceptibilidade ao tumor que homens brancos de mesma idade. Tratando-se de genética, as variações em alelos de genes que controlam o metabolismo de andrógenos influenciam na incidência do tumor. Quanto à nutrição, pesquisas confirmam a influência de alimentos como: carne, gorduras e óleos, sorvetes, margarina e gordura vegetal. Descritores: neoplasias; próstata; epidemiologia.RESUMENObjetivos: realizar una revisión sistemática de datos epidemiológicos sobre la incidencia de cáncer en el mundo.
