PHOTOBIOMODULATION ON MUSCLE STRENGTH AND FATIGUE IN MULTIPLE SCLEROSIS: SYSTEMATIC REVIEW

Background: Photobiomodulation plays an important role in modulating the inflammatory process, accelerating tissue repair, which can be beneficial in cases such as multiple sclerosis. Objective: To carry out a literature review about effectiveness of photobiomodulation on muscle strength and fatigue in multiple sclerosis. Methods: The databases included were PubMed, Embase, Cochrane, Web of Science, Scopus and LILACS (Latin American and Caribbean Health Sciences Literature). Also the gray literature: Google Scholar, LIVIVO (ZB MED Search Portal for Life Sciences), Open Grey and Library of Thesis and Dissertations CAPES (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior). The risk of bias was assessed using the Cochrane tool, Rob 2, and the data was extracted and assessed by blinded reviewers. Results: Initially 7302 records were found, 7102 in the main databases and 200 in the gray literature. After removing duplicates, 4217 studies were left for Phase 1 and 10 for Phase 2. Finally, 3 randomized clinical trials were included in this review. Conclusion: The studies included risk of bias in this review was predominantly low. PBM proved to be effective in improving muscle strength, but not fatigue. However, the number of human clinical trials is still too few for a more conclusive analysis.

ALFABETIZAÇÃO DE ESTUDANTES CEGOS: O QUE REVELA A PRODUÇÃO PERIÓDICA NACIONAL?

ABSTRACT: This review article catalogs and analyzes Brazilian scientific articles on blind people's literacy. To this end, we carried out a systematic search by subject on the Portal de Periódicos of the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). As a corpus for analysis, we found only seven national scientific articles published between 2007 and 2022 in different journals, without any identifiable patterns regarding their insertion, frequency, and bibliographic dissemination. Amongst them, only three are indexed in the Scielo database. The articles, in short, show the relevance of Braille for blind learners' initial learning of reading and writing. However, their samples present limited and reduced data, mainly due to the small number of blind participants. The space-time of the inclusive standard class was absent from the articles, which mainly dealt with institutions or specialized contexts. In addition, the authors' research contexts and institutions are concentrated in the Brazilian Southeast-South regions. Furthermore, theoretical-methodological insufficiencies persist in scientific research communication. Therefore, we recommend new and broader studies exploring the interfaces between literacy and blindness in Brazil, with the dissemination of their results in scientific journals.

Métodos de avaliação institucional que incluem o corpo discente em faculdades de Medicina: uma revisão sistemática

Abstract Introduction: Institutional evaluation is an important tool for the constant improvement of medical courses, especially when they take the student’s opinion as one of their focuses. Objective: The main objective of this study is to investigate which methods are used to conduct institutional evaluations involving student opinion through a scoping systematic review. Methodology: In compliance with the “Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR)”, the searches were conducted in a standardized form, involving at least two researchers and consulting the Lilacs, Scielo, Pubmed, and Embase databases and the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), using the software Rayyan, to signal duplicates and allow an independent and unbiased evaluation by the two reviewers. The inclusion criteria used were: Studies published between 2009 and 2019, containing the methodology of evaluation, which assessed medical courses and in which this evaluation was carried out by students at some stage. Also, the following exclusion criteria were used: studies written in languages other than Portuguese, English, French and Spanish; evaluations of a specific pedagogical intervention or limited to some subjects; and articles focusing on student self-assessment. The restriction of time and languages carries the risk of selection bias. Results: 2355 records were found and 12 articles were included. Most studies created their questionnaire and used mostly quantitative scales, although many also included some type of qualitative analysis with written questions. Most of the studies dealt with an occasional analysis and not with a project of permanent evaluation of the institution. Conclusion: Publications in the field of institutional evaluation that involve students and describe the questionnaire are still rare, especially when related to permanent evaluations.

Method This is a scope review using the methodology of the Joanna Briggs Institute (JBI). The protocol was registered on the Open Science Framework (OSF) platform, DOI: 10.17605/OSF.IO/RP9EV. The search was conducted in the following databases: MEDLINE/PubMed, Web of Science, LILACS, BDENF, SCOPUS, and Cochrane, as well as grey literature available on Google Scholar and the Theses and Dissertations Portal of the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). The search and screening process took place in August and September 2022. Published studies with full-text available were included without language or time frame limitations. Descriptors and keywords were used, combined with boolean operators OR and AND: Older woman, old woman, aged, aged 60 and over, seniors, older adults, elderly, educational practices, health education, constructs of Paulo Freire, liberating education, Paulo Freire. Results The total number of included studies consisted of 16 publications, predominantly qualitative approaches and experiential reports. The publication years ranged from 1999 to 2021, with languages identified as Portuguese and English. Educational practices were organized following the framework of Paulo Freire, with cultural circles, workshops, and games being the most addressed topics. Conclusion The studies showed that educational practices are participatory and dialogical, and they may contribute to empowering older women in terms of self-care.

Verification of the peculiarities of the Anthophoridae Family (Insecta: Hymenoptera)

Solitary behavior is characterized by the independence of females in building and provisioning their nests. There is no cooperation, or division of labor, between females of the same generation, or between mother and daughters. Most of the time, the mother dies before her offspring emerges, with no intergenerational relationships. There is a great diversity of nesting habits among solitary bees. Several species of the Megachilidae, Anthophoridae, and Apidae families nest in hollow branches of plants or pre-existing holes in wood. Others nest in cavities on the ground or in ravines or in protected places and few build exposed nests. The objective of this manuscript is to know the peculiarities of the Anthophoridae Family. The study proposed here constitutes bibliographical research in national and international publications that address the Anthophoridae (Insecta: Hymenoptera: Apoidea) in the field of Entomology. The bibliographical research was carried out using the descriptors Hymenoptera, wasps, and bees in the virtual library in Entomology and in the digital library of theses and dissertations of Universidade de São Paulo (BDTD). Concerned with drawing a public profile of quality research in the area, we sought, a literature review in the main journals in the area classified by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). In order to complement this analysis with other types of documents such as books, scientific journals, and documents.

Prevalence of HIV-1 infection and associated characteristics in a Brazilian indigenous population: a cross-sectional study

Despite significant progress in the areas of prevention, diagnosis, and treatment, HIV continues to result in a substantial number of fatalities on a global scale each year. Gaining insights from epidemiological data can prove instrumental in the development of health promotion strategies, particularly within vulnerable populations, such as indigenous groups. Consequently, our study aimed to investigate the prevalence of HIV infection within the indigenous population residing in the second-largest region of Brazil. Additionally, we sought to explore the subtypes of HIV-1 and detect any drug-resistance mutations present within this population. In this cross-sectional study, we aimed to evaluate the prevalence of HIV-1 infection and explore its associated characteristics within the indigenous population residing in the villages of Jaguapiru and Bororó, located in the Dourados area of Mato Grosso do Sul (MS), Brazil. Blood samples were collected for rapid HIV screening, serological tests, nucleic acid amplification, and HIV subtyping. Additionally, the HIV-1 viral load and CD4+ T lymphocyte count of the people living with HIV (PLHIV) were assessed at the time of recruitment and 24 weeks later. Out of the 2190 invited individuals, 1927 (88%) were included in this study. The average age of the participants was 34.2 (±13.8) years, with a majority of 74% being female. Moreover, 68.44% of the participants identified themselves as belonging to the Guarani-Kaiowa ethnic group. HIV seroprevalence was 0.93% (18/1927), and 73.22% (1411/1927) were unaware of their serological status. The prevalence of HIV-1 was higher in single indigenous people [10/617 (1.62%)], who received government benefits [14/1021 (1.37%)], had less than five years of formal education [11/685 (1.61%)], had sexual intercourse with users of injectable drugs [2/21 (9.52%)], with history of sexually transmitted infections (STIs) [10/62 (16.2%)] and incarceration [3/62 (4.84%)]. Of 18 positive samples, 44.4% (8/18) were successfully amplified, and HIV-1 subtype C was prevalent. Furthermore, we identified HIV-1 drug resistance mutations in four patients, specifically from the classes of Protease Inhibitor, Nucleoside Reverse Transcriptase Inhibitor, and Non-Nucleoside Reverse Transcriptase Inhibitor. Notably, three of these patients exhibited a high viral load even after 24 weeks of undergoing antiretroviral therapy. Out of the 18 PLHIV, 66.66% (12/18) had a viral load below 1000 copies/mL, while 50% (9/18) had a CD4+ T lymphocytes count greater than 350cells/mL after 24 weeks of treatment. Despite the concerted efforts to control HIV infection, the prevalence observed in the indigenous population under study surpassed that reported in other Brazilian indigenous groups. This disparity highlights the disproportionate impact of the disease on this particular group. The detection of drug-resistance mutations further emphasizes the critical need to expand diagnostic coverage, closely monitor treatment strategies, and maintain ongoing molecular surveillance. These measures are imperative for enhancing HIV management within this vulnerable population.

0021 Bimodality prevalence in a sample of undergraduate students in Sao Paulo city

Abstract Introduction The concept of bimodality comprises a fourth circadian phenotype, the bimodal, whose identification is made by a re-scoring of the Morningness-Eveningness Questionnaire and was first described by Martynhak and colleagues in 2010. Bimodal subjects are originally classified as “intermediate” because they answer the questions sometimes as a morning person and, some others, as an evening one. The present work aimed to describe the prevalence of the bimodal chronotype in a sample of undergraduate students in Sao Paulo city. Methods A web-based cross-sectional study conducted between September 2018 and March 2021, with a convenience sampling method, composed by 615 undergraduate students (82% females, mean age: 23.4±6.5 years) from two higher education institutions at Sao Paulo city. Results Forty-four students (7%) had positive bimodality indexes and bimodal individuals comprised 19 students (74% female; 26% male), 3% of the total sample. Conclusion We met our initial goal and found a bimodality prevalence of 3%. The description of bimodality prevalence in a sample of college students is interesting because they may be a maladaptive population from a sleep and rhythmicity point of view, which may be interesting for the design of academic public policies more consistent with the circadian preferences of students.

0688 Nocturnal pain and its association with quality of life in women: data from the Epidemiologic Sleep Study (EPISONO)

Abstract Introduction It is known that poor sleep is related to pain, even though this relationship is not fully understood. Women with pain present alterations in sleep pattern and reduced quality of life, but little is known about the negative effects of nocturnal pain on these outcomes. This study aimed to evaluate and compare the levels of anxiety, depression, and fatigue in women with pain during the night with those without pain. We hypothesize that pain perception is associated with worsening fatigue and mood outcomes. Methods This cross-sectional study used data from the 2007’s Epidemiological Study of Sleep (EPISONO). A total of 574 women aged 20-80 years participated in the EPISONO, and 244 women met the inclusion criteria of our study, 85 in the pain group and 171 in the control group. Participants were categorized into the pain group if they responded positively to the following questions: i) they generally had pain, according to the Pre-Sleep Questionnaire (PSQ), and ii) pain usually interfered with sleep 3 or more times a week, according to the Pittsburg Sleep Quality Index (PSQI). Participants who responded negatively to these questions were allocated to the control group. All of them underwent a full night laboratory polysomnography, and answered questionnaires related to fatigue, depression, anxiety, and quality of life. Results Significantly higher levels of fatigue (5.4 times), anxiety and depression were observed in the pain group, as well as significantly lower values in all domains of quality of life, compared to the control group. The presence of pain at night was also correlated with levels of anxiety and depression in the psychological (Rs=-0.463, -0.607, respectively) and social (Rs=-0.423, -0.438, respectively) domains of quality of life. Conclusion The presence of pain at night in women is related to a decrease in quality of life and can lead to worsening mood disorders and fatigue. Our results show the importance of investigating pain and its consequences, as well as the interference in women's sleep patterns.

0410 Lavender essential oil and sleep hygiene as therapeutic options for insomniac postmenopausal women: a randomized clinical trial

Abstract Introduction Menopausal transition and postmenopause often bring sleep complaints and insomnia, a common sleep disorder. In addition, women at this stage also experience vasomotor symptoms, which can compromise sleep maintenance and quality of life. This study aimed to observe the effect of an intervention with aromatherapy and sleep hygiene in the quality of life, self-related sleep pattern and hot flashes record in postmenopausal women with insomnia diagnosis. Methods This pilot study is a double-blind randomized clinical trial. Of the 135 women interested in participating in the study, 34 postmenopausal women met the inclusion criteria and completed the protocol. Volunteers were clinically diagnosed with insomnia and distributed in two groups: Aroma Group (Lavandula angustifolia essential oil) (n=17) and Placebo Group (sunflower oil) (n=17), both inhaled before bedtime for 29 days. The groups received sleep hygiene guidelines and were monitored weekly. To assess the effect of the intervention, the Menopause-Specific Quality-of-Life Questionnaire, intervention version (MENQOL-I), and Epworth Sleepiness Scale (ESS) were used. With data from the sleep diary, we evaluated sleep onset latency (SLO), total sleep time (TST) and sleep efficiency (SE) daily. Additionally, participants who complained of vasomotor symptoms were invited to fill out a hot flashes form, reporting the presence or absence of these symptoms, daily amount, and its intensity. Results The therapeutic approaches in this study benefited participants in both groups in almost all domains of quality of life and self-rated sleep patterns such as TST and SE. Particularly, the lavender essential oil intervention provided significant improvement in the overall quality of life score over time. No differences were observed considering the hot flashes record and sleepiness. Conclusion The aromatherapy intervention was effective in improving overall quality of life in the Aroma group. Furthermore, strategies such as sleep hygiene and a sleep diary helped participants to self-assess their sleep routine and improve it.

0466 Effect of Obstructive Sleep Apnea and CPAP on Telomere Length and its Associated Mechanisms

Abstract Introduction Growing evidence suggests the contribution of obstructive sleep apnea (OSA) in the molecular pathways of aging related to the maintenance of telomere length. The present study aimed to investigate the effect of OSA and its treatment with continuous positive airway pressure (CPAP) on the variation of telomere length and its associated mechanisms. Methods For this, a 6-month randomized, double-blind and sham-controlled clinical trial was conducted. Participants were randomized to CPAP or sham-CPAP and attended 7 visits, in which they underwent clinical assessment and had their blood collected to determine mean leukocyte telomere length (LTL) and the dosage of metabolic and inflammatory markers. Results Among 127 individuals that we contacted, 46 met the inclusion criteria. At baseline, individuals in both groups were homogeneous, including LTL (p=0.106). Adherence during the intervention was 5.29 ± 1.09 in the sham-CPAP group and 5.71 ± 0.19 in the CPAP group. After 6 months of intervention, we observed a statistically significant effect of the treatment (p=0.001) on LTL, in which the sham-CPAP group (1.0117 ± 0.1552, 0.9457 ± 0.0747, 0.8482 ± 0.2163) showed a more significant reduction than the CPAP group (1.0960 ± 0.1122, 1.0521 ± 0.1094, 1.0675 ± 0.1225). Furthermore, we found a negative correlation between delta LTL and dela TNF-α at Visit 7 and Visit 1 (rho=-0.216, p=0.003) due to the sham-CPAP intervention (rho=-0.383, p=0.009) in relation to the use of CPAP (rho=0.021, p=0.800). Conclusion We can conclude that CPAP, when compared to sham-CPAP placebo, caused an effect on LTL stability, potentially by the modulation of TNF-α.

Onset of chaotic gravitational lensing in non-Kerr rotating black holes with quadrupole mass moment* *Supported by the National Natural Science Foundation of China (NNSFC, 12005077) and Guangdong Basic and Applied Basic Research Foundation (2021A1515012374). We also gratefully acknowledge the financial support from Brazilian agencies Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP), Fundação de Amparo à Pesquisa

In the electromagnetic channel, chaotic gravitational lensing is a peculiar phenomenon in strong gravitational lensing. In this study, we analyze the properties and emergence of chaotic gravitational lensing in the Manko-Novikov black hole spacetime. Aiming to better understand the underlying physics, we elaborate on the boundaries of the accessible region through analyses of the contours of the effective potentials. The latter is associated with the two roots of a quadratic equation. In particular, we explore its interplay with an ergoregion, which leads to specific features of the effective potentials, such as the emergence of a cuspy edge and the formation of a pocket, which serve as static constraints on the geodesics. Additionally, we investigate the properties of the radial and angular accelerations at the turning points in photon trajectories. The accelerations are further examined and may provide kinematic constraints on the geodesics, as argued herein. It is concluded that the onset of the chaotic lensing is significantly related to both constraints; as a result, an arbitrary slight deviation in the incident photon is significantly amplified during evolution through an extensive period, demonstrating the complexity in the highly nonlinear deterministic gravitational system.

Oxygen uptake efficiency slope measured by cardiopulmonary exercise testing: applicability analysis of the available prediction equations in a Brazilian healthy sample

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) and Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq). Background Oxygen uptake efficiency slope (OUES) measured by cardiopulmonary exercise testing (CPET) is a measure derived from submaximal oxygen uptake values and has prognostic significance in heart failure patients. Measured values are compared to reference standards for an adequate individual assessment. However, current reference values prediction equations have applicability limitations due to differences in ergometer and sample characteristics (age range and nationatilies), which may impact external validation, as international heterogeneities in peak oxygen uptake values have already been demonstrated by Milani et al. and Peterman et al. Purpose To analyze the applicability of the available prediction equations for OUES in a healthy Brazilian sample from the Midwest region. Methods Cross-sectional study of subjects assessed by treadmill CPET in the Brazilian Midwest region between January/2011 to March/2020. The inclusion criteria were CPET performed on a treadmill in healthy subjects aged 20 years or older, and with respiratory exchange ratio ≥ 1.0. The exclusion criteria were any history of cardiovascular or pulmonary disease, presence of cardiovascular risk factors (such as hypertension, diabetes mellitus, current smoking, and obesity) and abnormalities on CPET. The following available prediction equations were used for comparisons with the measured OUES: 1) Buys et al. from Belgium/Netherlands; 2) Hollemberg et al. from United States; 3) Sun et al. from United States; 4) Brazilian prediction equations calculated in our same sample using sex, age and anthropometric variables. Statistical comparisons between measured and predicted OUES were performed using Spearman correlation test and Bland-Altman agreement analysis. Results During the study period, 7,843 CPETs were performed and included for eligibility. After applying the inclusion and exclusion criteria, 3,544 assessments of healthy individuals were included (1,574 women; 1,970 men; age 20 to 80 years). All correlations between measured and predicted values were significant, with rho ranging from 0.325 to 0.396 in females and from 0.391 to 0.450 in males (Figure 1). The mean errors by the Bland-Altman agreement analysis were heterogeneous between the OUES predition equations, with better results in our Brazilian equation. Greater bias were observed in the equation by Sun et al. for both sexes, in the equation from Buys et al. for females and in the equation by Hollemberg et al. for males (Figure 2). Conclusions The applicability analysis of the international prediction equations for OUES revealed great heterogeneity, limiting the external validation of the available equations, and highlighting the importance of using country-specific reference values for OUES to ensure a correct individual evaluation.

Peak oxygen uptake during treadmill cardiopulmonary exercise testing: applicability analysis of the FRIEND registry prediction equation in a Brazilian healthy sample

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq). Background Peak oxygen uptake (VO2peak) measured by cardiopulmonary exercise testing (CPET) is an important marker for health, physical performance and cardiovascular prognosis. Measured values are compared to reference standards for an adequate individual assessment. However, regional and international heterogeneities for VO2peak values have already been demonstrated by Milani, which may limit the external validation of the predictive equations developed in different nationalities. One of these equations was developed in an American population sample (FRIEND Registry) by Myers, but this equation has never been evaluated for portability in a population sample from the Brazilian Midwest region. Purpose To analyze the applicability of the FRIEND registry prediction equation for treadmill VO2peak in a healthy Brazilian sample from the Midwest region. Methods Cross-sectional study of subjects assessed by CPET in the Brazilian Midwest region between January/2011 to March/2020. The inclusion criteria were CPET performed on a treadmill in healthy subjects aged 20 years or older, and with respiratory exchange ratio ≥ 1.0. The exclusion criteria were any history of cardiovascular or pulmonary disease, presence of cardiovascular risk factors (such as hypertension, diabetes mellitus, current smoking, and obesity) and abnormalities on CPET. Variables were described as median and interquartile range. Statistical comparisons between measured and predicted VO2peak were performed using Spearman correlation test, Wilcoxon signed rank test, and Bland-Altman agreement analysis. Results During the study period, 7,843 CPET were performed and included for eligibility. After applying the inclusion and exclusion criteria, 3,544 assessments of healthy individuals were included (1,574 women; 1,970 men; age 20 to 80 years). The measured and predicted VO2peak were, respectively, 29.4 (25.1; 33.9) and 33.1 (29.5; 36.2) mL/kg/min in females, and 39.4 (34.3; 43.9) and 42.2 (39.1; 45.0) mL/kg/min in males, with significant differences (p < 0.0001). Correlations were significant (p < 0.0001) for both sexes (rho = 0.418 in women and 0.432 in men) (Figure 1). The mean error by the Bland-Altman agreement analysis was similar in both sexes, with a bias of -2.96 mL/kg/min (95% limits of agreement: -14.96 to 9.04 ) in females and a bias of -2.78 mL/kg/min (95% limits of agreement: - 15.39 to 9.83) in males (Figure 2). Conclusions The median values of the measured VO2peak were lower than the predicted values for both sexes, with a significant mean error, which limits the applicability of the FRIEND registry prediction equation in the Brazilian Midwest region population and highlights the international heterogeneity of the variable.

Echoes of axial gravitational perturbations in stars of uniform density* *Supported by the National Natural Science Foundation of China (42230207) and the Brazilian Agencies Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP), Fundação de Amparo à Pesquisa do Estado do Rio de Janeiro (FAPERJ), Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), Coordenação de Aperfeiçoamento de Pessoal

This study investigates the echoes in axial gravitational perturbations in compact objects. Accordingly, we propose an alternative scheme of the finite difference method implemented in two coordinate systems, where the initial conditions are placed on the axis of the tortoise coordinate with appropriate boundary conditions that fully respect the causality. The scheme is then employed to study the temporal profiles of the quasinormal oscillations in the Schwarzschild black hole and uniform-density stars. When presented as a two-dimensional evolution profile, the resulting ringdown waveforms in the black hole metric are split into reflected and transmitted waves as the initial perturbations evolve and collide with the peak of the effective potential. Meanwhile, for compact stars, quasinormal oscillations might be characterized by echoes. Consistent with the causality arguments, the phenomenon is produced by the gravitational waves bouncing between the divergent potential at the star's center and the peak of the effective potential. The implications of the present study are also discussed herein.

O TRANSTORNO DO ESPECTRO AUTISTA E AS REPRESENTAÇÕES SOCIAIS DE PROFESSORES: UMA REVISÃO DE LITERATURA EM PRODUÇÕES ACADÊMICAS BRASILEIRAS

The present research aimed to investigate the state of knowledge regarding the social representations of teachers about students with Autism Spectrum Disorder (ASD), based on stricto sensu productions published in Brazil between 2005 and 2021. The methodological procedure used in this literature review was a systematic survey of dissertations and theses regarding the social representations of professors about students with ASD in the Brazilian Digital Library of Theses and Dissertations (BDTD), acronym in Brazilian Portuguese) and Catalog of Dissertation and Theses of the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) databases. After applying the inclusion and exclusion criteria, six works were selected, of which five dissertations and one thesis, to compose the analysis. As a result, we identified that most professors are stucked in social representations marked by prejudice and stereotypes. Therefore, it is necessary a broad and continuous clarification of the potential of these students in order to attitudinal changes may occur. We conclude that it is extremely important to carry out further research and studies that approach the theme of social representations and ASD in the academic environment, based on the scarce literature on the subject.

Considerations for continued expansion of the Brazilian post-graduate system

The number of programs and students in the Brazilian postgraduate system has doubled in the last 10 years. This has implications for the quality and financing of these programs as well as for the development of the regions where they are set. This study aims to investigate the reasons and limitations for the continued expansion of the Brazilian postgraduate system. Data (2011 to 2020) for this study came from: (i) the “Sucupira” postgraduate database from the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), (ii) Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (INEP), (iii) Brazilian Institute of Geography and Statistics (IBGE), (iv) InCites® and Web of Science data, and (v) questionnaire and meetings with the deans for Higher Education Institutions (HEIs) in Brazil. Data analyses included regression over time, frequency chi-square, and correspondence analyses. Different types of institutions in different regions showed varying opinions, with higher expectations for expansion in smaller, newer institutions, especially private ones. While the HEIs in the Northern region believe that the master’s degree is to correct undergraduate flaws, the HEIs in the South and Central regions and the community believe that the master’s degree should develop professional skills. In contrast, the larger HEIs with older postgraduate programs in all regions believe in direct doctorate strategy. The reasons for creating new post-graduate programs involved following the institution’s general guidelines for private and community HEIs and granting the lecturers’ wishes or constant expansion depending on region, North, Northeast, and Central regions, as well as for creating medium-sized state universities. State-of-the-art research or the interests of society were prevalent for the largest and oldest HEIs. Continued expansion of the Brazilian postgraduate system needs to take into account factors including the demand for the program, regionalization, the quality of the programs, the means of funding, and the student vacancies existing in programs with high grades, among other challenges.

Youth Well-being: Exploring Models and Instruments

Well-being is a phenomenon widely studied in the health field. Specifically in Psychology, well-being has been studied from different perspectives ranging from the cognitive evaluation of one's own life to positive functioning at different levels. Considering the different perspectives of studying well-being, this study carried out a scoping review with the objective of mapping the main models and instruments used to evaluate the phenomenon in the adolescent population in the last five years. The publication search strategy used the Periodicals Portal of the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), including articles in Portuguese, English and Spanish, peer-reviewed, complete in the databases, with samples between 12 and 18 years old. The main findings of this review indicate a plurality of well-being models that derive from five main approaches, namely subjective well-being, psychological well-being, quality of life, wellness and mixed approaches. The proliferation of well-being models can generate theoretical divergences and conflicting interpretations, which directly impact the generalization of data, compromising the development of health interventions and policies. Also noteworthy is the gap in studies that investigate gender disparities and the nuances of racial and ethnic identity in relation to well-being in adolescence. These gaps suggest the need for more inclusive research that is sensitive to the particularities of adolescents to promote a more complete and effective understanding of well-being at this crucial stage of development.

A Rede de Atenção às Urgências e Emergências no Brasil: revisão integrativa da literatura

Abstract The Urgent and Emergency Care Network (RUE) was proposed in Brazil as a public policy to articulate and integrate the health services of the Brazilian National Health System (SUS), expanding and qualifying the access of users in e emergency health situations in an efficient and timely manner. This study analyzes the scientific production on the RUE in Brazil and elaborates summaries showing the limits and challenges of this health policy. An integrative literature review was used as a method, based on the search for articles in the LILACS, SciELO, and MEDLINE databases and for dissertations and theses on the virtual platform of the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). The investigation enabled the analysis of 34 studies in the field of collective health, focused on the different emergency services and the integration between them, including possible changes in the health care process and different evaluation strategies, by using different approaches, mainly qualitative.

By analyzing the propagation of discontinuity in nonlinear electrodynamics, we numerically investigate the related black hole shadows of recently derived rotating black hole solutions in gravity. In this context, the geodesic motion of the relevant perturbations is governed by an effective geometry, which is closely related to the underlying spacetime metric. We derive the effective geometry, and the latter is used to determine the trajectory of the propagation vector of an arbitrary finite discontinuity in the electrodynamic perturbations, namely, the photon. Subsequently, the image of the black hole is evaluated using the ray-tracing technique. Moreover, we discuss the physical relevance of metric parameters, such as the nonlinear coupling, spin, and charge, by studying their impact on the resultant black hole shadows.

Peak ventilation during treadmill cardiopulmonary exercise testing: applicability analysis of the FRIEND registry prediction equation in a Brazilian healthy sample

Abstract Background Peak ventilation (VEpeak) measured by cardiopulmonary exercise testing (CPX) is a valuable clinical information, especially in patients with pulmonary diseases. Measured values can be compared to maximal voluntary ventilation or to predicted VEpeak calculated by nonexercise equations. However, the FRIEND Registry prediction equation has never been assessed for portability in a Brazilian population sample. Purpose To analyze the applicability of the FRIEND registry prediction equation for VEpeak during treadmill CPX in a Brazilian healthy sample. Methods Cross-sectional study of subjects assessed by CPX in the Brazilian Midwest region between January/2011 to March/2020. The inclusion criteria were CPX performed on treadmill in healthy individuals aged 20 years or older, and with respiratory exchange ratio ≥1.0. The exclusion criteria were any history of cardiovascular or pulmonary disease, presence of cardiovascular risk factors (such as hypertension, diabetes mellitus, current smoking, and obesity) and abnormalities on CPX. Measured VEpeak values were compared with predicted values calculated using age, sex, and height, according to the FRIEND Registry prediction equation. Variables were described as median and interquartile range. Statistical comparisons between measured and predicted VEpeak were performed using Spearman correlation test, Wilcoxon signed rank test, and Blant-Altman agreement analysis. Results During the study period 7,843 CPX were performed and included for study eligibility. After the inclusion and exclusion criteria were applied, 3,544 healthy individuals' assessments were included [1,574 females and 1,970 males, age 39 (33, 47) years]. The measured and predicted VEpeak were, respectively, 76.8 (66.7, 87.4) and 76.2 (68.5, 83.0) L min–1 in females, with significant difference (p=0.004). In males, the measured and predicted VEpeak were, respectively, 123.0 (107.3, 137.3) and 114.8 (107.5, 120.7) L min–1, also with statistical difference (p<0.001). Correlations were significant (p<0.001) for both sexes (r2=0.424 for females and .421 for males) (Figure 1). Average error was lower for females than males, with bias of 1.22 L min–1 (95% limits of agreement: - 26.95 to 29.39) in females and bias of 8.41 L min–1 (95% limits of agreement: −33.04 to 49.87) in males (Figure 2). Conclusion Measured VEpeak median values were greater than predicted median values for both sexes, with lower average error in females than in males. The significant average error in males limits the prediction equation applicability in the Brazilian population. Thus, the development of a new Brazilian prediction equation is necessary to better evaluate the variable response during CPX in Brazil.
