Analysis of productions on age/year distortion and Public Policies on the learning gap and correction of the school flow

This article presents a survey of recent productions that deal with the theme of age/year distortion and public policies on the learning gap and correction of the school flow. The research was carried out following the procedures of the "state of knowledge", as proposed by Marília Morosini (2015). A descriptive bibliometric study was carried out, with a qualitative-quantitative approach, using the databases Brazilian Digital Library of Theses and Dissertations and SciELO Citation Index (Web of Science). After a detailed analysis of the selected studies, it was possible to assess that the age/year distortion indexes have been decreasing over the years, mainly due to the adoption of public policies aimed at this purpose. However, there is still a long way to go, among them, ensuring effective learning and not simply automatic approval.

The importance of sustainable practices and whole foods in Brazilian schools

This review article analyzes the importance of sustainable practices and whole foods in Brazilian schools. The qualitative data was collected from articles corresponding to the years 2018 to 2022, through access to: SCIELO, CAPES journal portal and the BDTD (Brazilian Digital Library of Theses and Dissertations) under the criteria: national and complete publications, and with the themes: (i) integral use of food; (ii) existence of the practice and incidences in the consumption of food in its entirety; (iii) investigation of the importance of sustainability and its implication today. Of the 23 articles, 14 were selected, with consultations on laws for discussion and analysis. The aim is to highlight the provocation and promotion of healthy food consumption. School communities provide food as one of the premises for forming healthy eating habits. Therefore, the SDGs: 2, 4 and 12 - zero hunger and sustainable agriculture, quality education and responsible consumption and production - are correlated with situations in which school meals reflect on food waste.

Conclusions: The studies highlighted the potential related to the use of mobile applications in pre-hospital care, contributing especially to improving patient safety and the quality of care provided in pre-hospital urgency and emergencies. The optimization of assistance and early diagnosis times was also shown as a contribution of applications to assistance, in addition to alerting to details that may be unnoticed.

UTILIZAÇÃO DO TESTE RÁPIDO MOLECULAR PARA TUBERCULOSE ENTRE PESSOAS PRIVADAS DE LIBERDADE: REVISÃO DE ESCOPO

ABSTRACT Objective: to map the repercussions of using the rapid molecular test for diagnosing tuberculosis among people deprived of liberty in the scientific literature. Method: this is a scoping review following the recommendations of the Joanna Briggs Institute and PRISMA for Scoping Reviews. The search was conducted using controlled and free vocabulary in the following databases: EMBASE, Scopus, MEDLINE, Cinahl, Academic Search Premier, LILACS and Web of Science, in the Brazilian Digital Library of Theses and Dissertations and Google Scholar. The materials which answered the review question were selected by two independent reviewers based on reading the titles, abstracts and publications. All types of studies and publications were included. The extracted data was subjected to narrative synthesis and presented graphically. Results: a total of 13 among the 461 publications found were included in the review. The studies pointed out the following repercussions of using the rapid molecular test in the prison population: increase in the diagnosis of cases compared to sputum smear microscopy; reduction in diagnosis time, initiating treatment and isolation; identification of strains resistant to antibiotic therapy; reducing the prevalence and occurrence of tuberculosis; high agreement of test results with culture results; lower cost of the test when carried out in groups of samples or when screening is carried out by radiography. Conclusion: the literature indicated that the rapid molecular test is relevant for combating tuberculosis in prison units, so its use should be considered by authorities and managers as a strategic tool for controlling the disease.

Afiliação dos estudantes negros e/ou de camada popular ao curso de medicina: uma revisão de literatura

Abstract This article’s theme is the affiliation of black and/or low-income students to the school of medicine and aims to present a literature review carried out by bibliographical survey in the Catalog of Theses & Dissertations repositories, from the Coordination for the Improvement of Higher Education Personnel (henceforth Capes – Portuguese acronym that stands for Coordenação de Aperfeiçoamento de Pessoal de Nível Superior) portal, Brazilian Digital Library of Theses and Dissertations (henceforth BDTD – Portuguese acronym that stands for Biblioteca Digital Brasileira de Teses e Dissertações), Scientific Electronic Library Online (Scielo) and Google Scholar. The descriptors used were “affiliation (afiliação)”, “black student (estudante negro)”, “low-income student (estudante de camada popular)”, “quota holder (cotista)”, “medicine course” (curso de medicina)” and “Coulon”, combined with the Boolean logical operator “and”. The searches privileged the Portuguese language, as it is the Brazilian university context and, after refinement, considering the temporal delimitation of the last five years and the relevance to the epistemological focus given to the study, 20 productions were selected. The results suggest that black and/or lowincome students are still the first in their families to enter university, which is perceived by them as a space for resignification and social mobility. Racial, social, and economic matters permeate their entire university trajectory. It is perceived that the quality of life of these students is compromised so that they can achieve academic success. Therefore, the relevance of welcoming and the involvement of the university in the process of affiliation of black and/or popular students and the absence of analysis of subalternity relationships in Coulon’s concept of affiliation are considered.

Mapeamento sistemático da produção de conhecimento na formação graduada em terapia ocupacional nos contextos territoriais e comunitários no Brasil

Abstract This article aims to recognize and dialogue with the production of knowledge, practices and, in particular, with undergraduate teaching in occupational therapy in territorial and community contexts, through the systematic mapping of articles, dissertations and theses published between 2012 and 2022. Bibliographic search was carried out in November 2022, through the SciELO virtual library, the Brazilian Digital Library of Theses and Dissertations (BDTD), the Brazilian Institute of Information in Science and Technology (IBICT) and the databases: Web of Science, Scopus and Latin American and Caribbean Literature in Health Sciences (LILACS). 40 productions were eligible, of those, 29 articles and 11 dissertations/theses. The results were analyzed based on thematic analysis, whose topics were: What is territorial and community teaching? Where does it occur? What pedagogical strategies? Who teaches? What challenges do you face? What are the guiding concepts? The results point to interdisciplinary, interprofessional, collaborative teaching with important attributes such as the teaching-learning-assistance process in the territory and in territorial services, including actors such as students, professionals, teams and the community, in addition to the teacher who proposes, articulates and mediates of this teaching. We conclude that the mapping presents a general overview of this teaching, highlighting encounters between theories and practices, from different sub-areas of occupational therapy, which, in addition to teaching, propose actions to transform educational, social, cultural and health conditions. However, we noticed that there are gaps in the literature in the area that explain how the concepts are linked to this training, producing specific reflections on the profession in different sub-areas.

The Impacts of Floods on the Health of Riverside Communities in the State of Maranhão: An Integrative Review

Purpose: Through this research, the aim is not only to identify problems but also to provide valuable insights for the formulation of public policies aimed at improving the living conditions and health of these communities, making them more resilient in the face of frequent climatic challenges. Theoretical framework: Floods contribute to the spread of waterborne diseases due to the contamination of water sources and the lack of access to clean water during flooding periods. The presence of pathogens, such as bacteria and viruses, in flooded environments increases the risk of gastrointestinal diseases, emphasizing the need for integrated approaches to control these illnesses. Method/design/approach: Initially, a comprehensive literature review was conducted on studies related to the impacts of floods on the health of riparian communities, with emphasis on the specific context of the State of Maranhão. Academic databases such as PubMed, Scopus, and the Brazilian Digital Library of Theses and Dissertations (BDTD) will be consulted to identify relevant research, theories, and concepts associated with the effects of floods on health. Results and conclusion: Among the 46 selected articles, a higher number focused on floods in the riverside communities of Maranhão (n=30). In second place are those related to health, though few include consequences related to floods (n=10). Fewer articles addressed the social and historical-cultural profile, as observed in (Chart 1) (n=6). The integrative review highlights the complexity and interdisciplinary nature of the impacts of floods on the health of riverside communities in the State of Maranhão. The evidence presented indicates the need for public policies that address not only immediate challenges but also underlying causes, promoting sustainable interventions centered on communities. Research implications: The main managerial, academic, and social contributions of the research include the clear identification of challenges faced by riverside communities in Maranhão during floods. Originality/value: The study adopts an interdisciplinary approach by not only considering the direct impacts of floods on health but also exploring the social and cultural dimensions of riverside communities. This integration of health, environment, and social sciences enhances the understanding of the challenges faced by these communities.

Urinary dialkylphosphate metabolites in the assessment of exposure to organophosphate pesticides: from 2000 to 2022.

The general population and workers are exposed to organophosphate insecticides, one of the leading chemical classes of pesticides used in rural and urban areas, in the control of arboviruses and agriculture. These pesticides cause environmental/occupational exposure and associated risks to human and environmental health. The objective of this study was to carry out an integrative review of epidemiological studies that identified and quantified dialkylphosphate metabolites in the urine of exposed populations, focusing on the vector control workers, discussing the application and the results found. Searches utilized the Pubmed, Scielo, and the Brazilian Digital Library of Theses and Dissertations (BDTD) databases between 2000 and 2021. From the 194 selected studies, 75 (39%) were with children/adolescents, 48 (24%) with rural workers, 36 (19%) with the general population, 27 (14%) with pregnant women, and 9 (4%) with vector control workers. The total dialkylphosphate concentrations found in the occupationally exposed population were higher than in the general population. Studies demonstrate that dialkylphosphates are sensitive and representative exposure biomarkers for environmental and occupational organophosphate exposure. The work revealed a lack of studies with vector control workers and a lack of studies in developing countries.

Mind, brain and education: neuropsychological contributions to executive function training in the classroom with students with ADHD

Attention Deficit Hyperactivity Disorder (ADHD) is one of the neurodevelopmental disorders with the highest incidence in children and adolescents. With multifactorial characteristics, ADHD leads to impairments in executive functioning, for example, in skills related to Executive Functions (EFs) such as behavior control, sustaining attention and mastering activity levels or impulses, usually leading to impairments in learning. The aim of this article was to carry out a literature review as a contribution of neuropsychology to training EFs in the classroom with students with ADHD. An exploratory study was carried out, followed by descriptive or experimental research. Searches were carried out in the Scientific Electronic Library Online (SCIELO), Biblioteca Virtual em Saúde-Psicologia Brasil (BVSPSI), Periódicos Eletrônicos de Psicologia (PEPSIC) databases, in the journals available in the Brazilian Digital Library of Theses and Dissertations (BDTD), in PUBMED and in textbooks. Covering publications from 2017 to 2023, 8 articles were selected for analysis. The bibliographic survey showed the importance of studies on ADHD related to EFs, and it is important for teachers to stimulate these functions, as studies have shown that they have minimized the impact on learning deficits in students with ADHD, and that they can consequently bring about better emotional regulation. This review provided evidence showing that EF training improves executive functioning, reducing ADHD symptoms and leading to improvements in academic functioning. It is suggested that further empirical research into EF intervention by educators for students with ADHD with greater breadth and sampling needs to be carried out.

Educational practices through information and communication technologies: integration between active methodologies

Improving the academic and professional background of people from varied levels make us rethink about the role of formal teaching strategies, considering that even today deficencies are displayd in learning environments. In its most noticeable phase, the traditional teaching is highly associated with school evasion, pragmatic learning and students’ discouragement to learn. There are several pedagogic recommendations made to the teachers in order to reverse this situation, but there are not many practical alternatives presented. Given the current context, this article aims at describing the integration between two active methodologies: Just in Time Teaching (JiTT) and Peer Instruction (PI), and the goal is to promote the potencial of both in the teaching and learning process. These methodologies make use of information and communication technologies (ICT) to their own functionality. But for that purpose, a sistematic review on integration between these methodologies was made in this research, being held at the database of SciELO, Scopus and Brazilian Digital Library of Theses and Dissertations, in the period 2015-2020. There have been found 311 articles and 1,663 theses/dissertations and, among all, 22 studies were selected, including national and international. The results have showed that the integration between active methodologies improved the students’ performances, considering their learning, development, autonomy to carry out studies, interactivity in search for learning, team work and proactivity; becoming protagonists of their own learning process.

A state-of-the-science review of analytical methods for urinary dialkylphosphate metabolites in the assessment of exposure to organophosphate pesticides: From 2000 to 2022.

The general population and workers are exposed to organophosphate insecticides, one of the leading chemical classes of pesticides used in rural and urban areas. This paper aims to conduct an integrative review of the most used analytical methods for identifying and quantifying dialkylphosphate-which are metabolites of organophosphate insecticides-in the urine of exposed workers, discussing their advantages, limitations and applicability. Searches utilized the PubMed, the Scientific Electronic Library Online and the Brazilian Digital Library of Theses and Dissertations databases between 2000 and 2021. Twenty-five studies were selected. The extraction methods most used were liquid-liquid extraction (LLE) (36%) and solid-phase extraction (SPE) (36%), with the SPE being more economical in terms of time and amount of solvents needed, and presenting the best percentage of recovery of analytes, when compared with LLE. Nineteen studies (76%) used the gas chromatography method of separation, and among these, 12 records (63%) indicated mass spectrometry used as a detection technology (analyzer). Studies demonstrate that dialkylphosphates are sensitive and representative exposure biomarkers for environmental and occupational organophosphate exposure.

This work investigated in the literature academic papers on the extraction of oil from macauba pulp and kernels and their cosmetic formulations based on this fruit. In the bibliographical systematization, we delimited the database: Google Academic, Capes Periodical, Scientific Electronic Library (SciELO) and Brazilian Digital Library of Theses and Dissertations (BDTD), filtered the works between the years 2018 and 2022, we defined the languages in Portuguese or English, the works as articles, dissertations and monographs. The information systematized brought the plant profile, the methods of oil extraction from both the pulp and the kernel of the macaúba, the extraction processes that have greater efficiency and safety of their products, thus becoming a reference for future research based on the species to subsidize the development of products for the food industry, cosmetics and pharmaceuticals.

Use of the Maslach Burnout Inventory Among Public Health Care Professionals: Scoping Review.

Work can be considered a source of living, well-being, and socioeconomic development. When the work environment negatively influences individuals, it may trigger emotional disturbances, behavioral problems, chronic stress conditions, and illnesses such as burnout syndrome (BS). Recently, studies on BS have increased and placed a special focus on health care professionals. The prevalence of BS among health professionals is associated with their chronic exposure to human hardship and long working hours without proper rest. These factors have contributed to greater stress and high physical and emotional exhaustion levels. This study aims to identify and map studies using the Maslach Burnout Inventory (MBI) scale to identify burnout syndrome in health professionals working in public health services. This scoping review was developed based on the Joanna Briggs Institute (JBI) Reviewers Manual and reported according to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews). A total of 6 databases were searched to identify relevant studies: Embase, LILACS, MEDLINE or PubMed, PsycInfo, Scopus, and Web of Science. Gray literature was consulted on ProQuest Dissertations and Theses Global, Google Scholar, Brazilian Digital Library of Theses and Dissertations, and Open Access Theses and Dissertations. Additionally, the reference lists were searched to retrieve studies not previously selected. The steps followed in this study were proposed by Arskey and O'Malley and Levac, Colquhoun, and O'Brien: identification of research questions, identification of potential studies, study selection, data extraction and imputation, data analyses and interpretation, and consultation with stakeholders. The detailed methodology was published in a protocol. A total of 55 articles were identified after screening for eligibility criteria, published between 1999 and 2021 in 32 countries. Most reports were published in Brazil, Spain, and China. A total of 22 versions of the MBI were identified, presenting different items, scores, and cutoff points. The included studies had recommendations and implications for clinical practice. The consultation with stakeholders allowed knowledge translation for those interested in BS. Studies mostly included physicians (34/55, 61.8%) and nurses (24/55, 43.6%), and the original version of MBI was predominantly used. Divergences in BS classification were highlighted, which may be related to MBI cross-cultural adaptations and applications in other countries. This study contributes to the advancement of research regarding burnout syndrome as an occupational illness since it has harmful consequences for workers, health care services, and the quality of care provided to the population.

Effectiveness in the removal of bioceramic sealers versus conventional sealers: systematic review and meta-analysis

This study aimed to carry out a systematic review to evaluate the effectiveness in removing bioceramic sealers compared to conventional sealers commonly used, evaluated through the percentage of remaining material. The electronic search was carried out in the following databases: MEDLINE (PubMed), Embase, Web of Science, Scopus, Cochrane Library, and in gray literature, at the Brazilian Digital Library of Theses and Dissertations (BDTD). Two independent researchers conducted the survey to identify the studies, without restrictions on year and language of publication, using the PICO strategy until the month of August 2020. A total of 80 titles were retrieved in the initial search, however, only 9 studies were included for the qualitative synthesis and 5 studies were included in the quantitative synthesis. The descriptive results indicated that the average time taken to remove the filling material was longer for bioceramics by approximately 67% of the studies that evaluated this condition, and with regard to the establishment of patency, no difference was detected between the sealers. It could be observed that bioceramic sealers presented a lower amount of remaining material than conventional sealers (p = 0.01) both in the overall analysis and in the analysis of subgroups. The removal of conventional sealer proved to be inferior to bioceramic sealers, with greater amounts of material remaining in the root canals after endodontic retreatment. The use of bioceramic sealers has gained space in the endodontic practice. However, it is not yet known whether these sealers affect the removal of root canal fillings during retreatments.

Scientific studies on Krav Maga: state of the art

This study aimed to analyze and synthesize the main concepts about Krav Maga in the last four decades. This is a review of the academic literature with a qualitative approach and a narrative nature. The searched databases are PubMed/Medline, Scopus, Web of Science, SciELO, Index Medicus, Capes Platform, ProQuest Digital Dissertations, Brazilian Digital Library of Theses and Dissertations (BDTD) and Google Scholar, between the years 1982 and 2022. Empirical studies with cross-sectional, longitudinal, case, control and randomized design were included, and books and private websites were excluded. The textual corpus was processed by the IRaMuTeQ software. Forty-four studies met the eligibility criteria, of which eighteen conceptualized Krav Maga as “self-defense”, twelve as “fighting”, seven as “hand-to-hand combat”, four as “self-defense art”, three as “cultural heritage” and immaterial” and another as a “hybrid system”. The main aspects evoked and addressed in the research were: Operational and Military, Historical, Pedagogical, Psychosocial and Physiological. Most studies had low to moderate methodological quality, indicating the need for greater control of biases in future research. In addition, it was evidenced that Krav Maga is a system, or method developed for self-defense, however, it is a polysemic term, and cannot be understood in a uniform and linear way.

PRÁTICAS COLABORATIVAS COMO PROPOSTA NA EDUCAÇÃO ESPECIAL: REVISÃO SISTEMÁTICA SOBRE FORMAÇÃO DOCENTE

Considering that collaboration is a principle that guides educational practice, the objective of the study was to understand the scientific knowledge about teacher training opportunities focused on collaborative practices in the school environment as a proposal in Special Education. This is a systematic literature review that used the Brazilian Digital Library of Theses and Dissertations (BDTD) as a data platform, considering all works in Portuguese, available until October 2022. 45 studies were found, 24 of which were dissertations. and 21 theses developed in graduate programs focused on the areas of Education and Special Education in Brazil. We consider it relevant to analyze the following components to know the selected research in detail: year, thesis or dissertation, method, participants, characterization of the students involved in the research, characterization of the training actions proposed to the participating teachers andLimitations found in the studies, for collaboration between professionals. As a result, we found that the works point out that training focused on collaborative practices favored teaching actions with Special Education Target Public (EPAEE) Students, improving teaching for all, but we observed that the studies showed limitations related to the lack of resources human resources and collective time among professionals to develop and establish joint work, in addition to the need for continued training for teachers.

Special Education Resource Rooms Type 1 in Brazil: An analysis of research objectives in dissertations on mathematics education

This article presents the results of an investigation aimed at analyzing research on Type 1 Multifunctional Resource Rooms (MRR1) in Brazil, materialized in the form of dissertations, in the teaching of mathematics at the levels of Elementary Education 2 and High School. The dissertations analyzed were accessed on the website of the Brazilian Digital Library of Theses and Dissertations (DLTD) through the following search triggers: "resource room", "mathematics", "intellectual disability", "teaching of mathematics", "mathematical games", and some restrictive details were highlighted in the methodological procedures. From this process, we selected 10 dissertations, which were analyzed in their completeness. However, for this article, we focused only on interpreting the research objectives presented by the authors of these productions. In our analysis, we constructed three categories from the themes presented in three axes, namely: Axis 1, concerns the perceptions, conceptions, and activities developed for the training of student teachers, beginning teachers, and/or those in practice in MRR1 for the teaching of mathematics; Axis 2 concerns the discussions, observations, and theorizations about MRR1 for the teaching of mathematics, and finally, Axis 3, which encompasses proposals and descriptions of activities as pedagogical resources in MRR1 for the teaching of mathematics.

Self-Care Requisites for People with Intestinal Ostomies: A Scoping Review

Self-care is one of the main factors altered in the life of a person with an ostomy. Self-care requisites with nursing support are necessary. Objectives: To map the self-care requisites for people with intestinal ostomies in their adaptive process, guided by Orem’s theory. Materials and methodology: A scoping review was conducted between May and June 2022, in which studies published from 2000 to 2022 were selected, based on Orem’s self-care deficit nursing theory. The sources of evidence used were Medical Literature Analysis and Retrieval System Online, Cinahl, Scopus, Latin American and Caribbean Health Sciences Literature, Nursing database, Índice Bibliográfico Español en Ciencias de la Salud, Web of Science, Scientific Electronic Library Online, Brazilian Digital Library of Theses and Dissertations, Open Access Scientific Repositories of Portugal, Theses Canada, DART-Europe E-Theses Portal, and National ETD Portal. Studies presenting at least one requisite of self-care for people with intestinal ostomies, whether or not they addressed Orem’s theory, and that were published in full were included. We followed the recommendations of the Joanna Briggs Institute and the PRISMA International Guide, registered in the Open Science Framework (10.17605/OSF.IO/XRH5K). The following descriptors and search strategies were used: (ostomy OR colostomy OR ileostomy OR stoma) AND (self-care OR self-management) AND (adaptation OR adjustment). Results: The final sample was composed of 87 studies. In universal requisites, studies in the category “nutritional aspects” predominated, of which the most frequent was “eat regularly and follow a balanced diet” (23; 26.4%); in developmental requisites, the prevalent category was “stoma and peristomal skin care” and requisite “assess peristomal skin integrity” (27; 31.0%); in the health deviation requisites, the predominant category was “choice of collection equipment and adjuvant products” and the requisite “use hydrocolloid powder to absorb moisture in cases of dermatitis” (13; 14.9%). Conclusions: The study contributes to guiding the assistance to the person with an ostomy, improving the self-care learning process. However, new intervention studies are still needed.
