RESUMO

INTRODUCTION: Xingu Indigenous Park (XIP) currently protects 16 ethnic Indigenous groups and is located in the central area of Brazil. XIP is the first and the largest Indigenous land to be recognized in the country. Community access is limited and restricted for the non-Indigenous population, and the Indigenous women are constantly dealing with shortages of medical care. High-risk human papillomavirus (HR-HPV) is the most common cause of cervical cancer and is detected in 99% of cervical precancers. HPV infections may be associated with bacterial agents such as Chlamydia trachomatis and Neisseria gonorrhoeae, which are also important causative agents of sexually transmitted infections and are responsible for the most frequent bacterial infections in the world. The present study evaluated the frequency and potential impact of Chlamydia trachomatis, Neisseria gonorrhoeae, and HR-HPV in the Indigenous women of XIP. METHODS: In this cross-sectional study, 992 cervical-vaginal samples were collected from Indigenous women, using a Cervex-Brush, and were immediately placed in a SurePath medium. All samples were submitted to the cobas® 4800 detection system for the identification of 14 different types of HR-HPV, and the multiplex Abbott RealTime CT/NG assay for the detection of Chlamydia trachomatis and Neisseria gonorrhoeae. RESULTS: HR-HPV was detected in 18.2% of women; 6% were positive for HPV16, 5% for HPV18, and 81% for other types of HR-HPV. Co-infections of HPV16 and other types was observed in 5% of women, and 3% had co-infections of HPV18 and other types. Moreover, 1.8% of women were positive for Chlamydia trachomatis, while Neisseria gonorrhoeae was not detected. In women with HR-HPV, 33% had Chlamydia trachomatis infections, 28% were positive for HR-HPV other than HPV16 or HPV18, and 5% had co-infections of HPV16 and the other types of HPV. Younger women were found to be more susceptible to HPV infections. CONCLUSION: The findings indicate a high frequency of HR-HPV and a considerable frequency of Chlamydia trachomatis in the Indigenous women of XIP. The detection of Chlamydia trachomatis, Neisseria gonorrhoeae, and/or HR-HPV does not present evidence of a potential interrelationship for a combined pathogenic action in these women.

RESUMO

Fluoride is one of the main phytotoxic environmental pollutants, and high concentrations (10-30 mg L-1) are commonly detected in surface and groundwater. Little, however, is known about the effects of this pollutant on crops that require irrigation during their development, which, in addition to phytotoxicity, may cause negative human health effects. Thus, the aim of this study was to characterize the effects of potassium fluoride (KF) on the germination of lettuce seeds and identify the physiological and anatomical markers of this pollutant's action on plants exposed to it during growth. Initially, lettuce seeds were sown in gerboxes and soaked in solutions containing 0 mg L-1, 10 mg L-1, 20 mg L-1, and 30 mg L-1 KF. Plants grown in a greenhouse were treated daily with KF irrigation at the same KF concentrations for 40 days. KF exposure reduced the germination rate and germination speed index of lettuce seeds at 20 mg L-1 and 30 mg L-1, resulting in compromised root development at the highest KF concentration. Lettuce plants displayed a slight photosynthesis reduction and a significant photochemical efficiency decrease after exposures to all KF concentrations. Lower chlorophyll contents and nitrogen balance indices were observed in plants exposed to 30 mg L-1 KF. On the other hand, increases in phenolic compounds and malondialdehyde were noted with increasing KF concentrations. Lettuce plants can, therefore, accumulate fluoride in leaves when irrigated with KF-rich water. The investigated physiological and biochemical variables were proven to be adequate fluoride action biomarkers in lettuce plants and may become an important tool in the study of olericulture contaminants.

RESUMO

Pterodon pubescens is a native Brazilian species typical of the cerrado biome, belonging to the Leguminosae-Papilionoideae (Fabaceae) family and popularly known as sucupira branca or faveiro. Its seeds exhibit different integument colors, which may exhibit a direct association to physiological quality related to higher germination percentage rates, vigor, and germination speed index (GSI). Therefore, selection and evaluation methods concerning P. pubescens seed quality are required for the preservation of this species. In this context, the aim of the present study was to determine the relationship between P. pubescens seed integument color and seed quality, through a combination of radiographic imaging and physiological, histochemical and biochemical assays. P. pubescens seeds were obtained from five matrices, and visually classified into four color classes, yellow, light brown, dark brown and black. The coordinates "L", "a" and "b", indicated by the colorimeter and the calculations of the chroma and hue angle values, verified that there was a difference in the color of the seeds, eliminating the subjectivity of the visual classification. Thus, the clearer the integuments, the greater their density, filling and α-amylase and ß-amylase hydrolytic enzyme activities, the latter comprising important germination power indicators, in addition to high ascorbate peroxidase (APX) enzyme activities, responsible for hydrogen peroxide (H2O2) elimination. Because of this, lighter colored seeds led to higher vigor, germination and GSI rates. The removal of darker seeds from P. pubescens seed lots guarantees higher germination rates and vigor of new plants in nurseries destined to recompose P. pubescens populations.

RESUMO

Background: Fluoride (F) is one of the main environmental pollutants, and high concentrations are commonly detected in the air and in both surface and groundwater. However, the effects of this pollutant on seed germination and on the initial growth of crop seedlings are still poorly understood. In this context, the aim of this study was to assess morphoanatomical, physiological and biochemical fluoride effect indicators in Phaseolus vulgaris L. seeds and seedlings. Methods: P. vulgaris seeds were exposed to a liquid potassium fluoride solution (KF, pH 6.0) at concentrations of 0 (control), 10, 20, 30 mg L-1 for 7 days. A completely randomized experimental design was applied, consisting of four treatments with four replications each. During the experimental period, physiological (7 days) anatomical and histochemical (2 days), biochemical and chemical (4 days) assessments. An analysis of variance was performed followed by Dunnett's test. to determine significant differences between the KF-exposed groups and control seeds; and a multivariate analysis was performed. Results: The germination parameters, and anatomical, morphological, physiological, biochemical and nutritional characteristics of the seedlings did not show negative effects from exposure to KF at the lowest doses evaluated. On the other hand, treatment with the highest dose of KF (30 mg L-1) resulted in a lower germination rate index and increase in abnormal seedlings, and higher electrical conductivity. A lower root length, magnesium content and photochemical efficiency were also observed. The exposure of P. vulgaris to KF, regardless the dose did not affect seeds anatomy and the accumulation of starch and proteins, in relation to the control group. Conclusions: Our findings demonstrated that P. vulgaris seedlings were tolerant to KF solutions up to 20 mg L-1, and sensitive when exposed to 30 mg KF L-1.

RESUMO

OBJECTIVE: To detect and treat cases of viral hepatitis B, C and D in patients seen at the Native American Outpatient Clinic of Universidade Federal de São Paulo. METHODS: This sample comprised 81 indigenous recruited between 2018 and 2020. Volunteers were aged 7 months to 70 years (mean age of 28±20 years), belonged to 26 ethnic groups spanning the Brazilian territory and answered a questionnaire, which was attached to their medical records. Peripheral blood samples (20mL) were collected, transported to the Clinical Laboratory of Hospital Israelita Albert Einstein, processed, and tested for markers of viral hepatitis B, C and D. RESULTS: In this study, 39 (48.1%) individuals were anti-HBs (+) only, 13 (16.0%) individuals were anti-HBs (+) and anti-HBc (+), and 28 (34.6%) individuals were negative for all markers. No anti-HBc IgM+ samples were found. No cases of hepatitis C and D were found. CONCLUSION: This analysis provided evidence of previous infection by the hepatitis B virus. These findings led to prescription of vaccination against hepatitis B to all participants who were negative for all viral hepatitis B markers, given records of prior hepatitis B vaccination were unreliable.

RESUMO

Efficient methodologies for automated seed quality evaluations are important for the seed industry. Advanced seed technology research requires the use of adequate methods to ensure good seed performance under adverse environmental conditions; thus, providing producers with detailed, quick, and accurate information on structural seed integrity and ensuring vigorous production. To address this problem, this study aimed to determine Brachiaria brizantha (Marandu cv., Piatã cv. and Xaraés cv.) seed quality through radiographic imaging analyses associated with vigor tests and anatomical characterizations. Brachiaria seed cultivars displaying different physical and physiological attributes were selected and subjected to the 1000-seed weight test, water content determinations, X-ray analyses, germination tests, and anatomical characterizations. The X-ray analyses made it possible to establish a relationship between the X-ray images and other determined variables. Furthermore, the X-ray images can indicate evidence of internal and external damage that could later compromise germination. The Marandu and Piatã cultivars presented the highest germination percentages, germination speed indices, normal seedling development, and cellular structure preservation compared to the Xaraés cultivar. To summarize, X-ray analyses are efficient methods used for the selection of higher physical quality cultivars and can aid in the decision-making processes of companies and seed producers worldwide.

RESUMO

Introduction: With the evolution of technologies, new digital resources have emerged establishing different practices in human behavior, including the excessive use of digital devices, causing different dependencies due to the nonconscious use of these technologies. The digital use of digital devices will always be very important to the organizational process, but the abusive or excessive use can bring performance problems at work and also for people. Collective environments of organizations also begin to show "symptoms" of these dependencies, and observing these behaviors can contribute to greater employees comfort and the functioning of the business organization. Objective: To identify the level of digital dependency of employees in organizational environments and to investigate this dependency associated with demographic characteristics. Method: Data collection took place online, from 11.05.2019 to 03.05.2020, with a sample totaling 307 volunteers and 13 questionnaires excluded due to filling error, ending with 294 valid questionnaires. A validated scale was used to Assess Digital Employee Dependence (EDDE), with 19 questions (Annex 1) and inserted in the Google Forms platform, widely used for data collection in surveys. After the collection procedure, a database was created for statistical analysis and discussion of the results. Results: Factor Analysis identified 4 factors using the Kaiser Method, via Scree Plot and 19 questions were maintained, according to previous applications of this questionnaire. The sample presented itself without digital dependence (42.2%) or with mild dependence (30.3%). Only women had a severe level of digital dependence, but with low significance (1.7%). Conclusion: The severe digital dependency had a very low score, while the sum of volunteers without dependence with a mild level characterizes a sample without relevant digital dependence. Women showed a higher level of digital dependence although more research needs to confirm this sign. The limitations found for applying the research did not compromise the results.

RESUMO

INTRODUCTION: The social distancing (SD) adopted during the coronavirus disease 2019 (COVID-19) pandemic has transformed the internet from a convenience into a necessity. The behavioral changes caused by isolation range from adaptation of consumption, work, and teaching routines to altered leisure options to occupy idle time at home. Such transformations can be positive, expanding use of digital technologies (DT), but they can also have serious future physical and emotional consequences if there conscious use of technological devices is lacking. OBJECTIVES: The study aimed to validate the Behavioral Changes Scale on the Use of Digital Technologies During Social Distancing (BCSDTSD), an instrument for assessing behavioral changes related to use of DT during SD. METHOD: Validation of the BCSDTSD in five phases: 1. construction of an initial scale with 10 questions; 2. evaluation of the questions by a panel of experts; 3. application to 1,012 volunteers via the internet; 4. statistical analysis of the results; and 5. preparation of the validated final version of the BCSDTSD. Data were analyzed using the dplyr, psy , and paran packages and the REdaS statistical program. Three statistical criteria were used in the factor analysis (FA). RESULTS: FA confirmed that all 10 questions in the questionnaire should be maintained, confirming its robust construction, and Cronbach's alpha demonstrated its internal consistency with a value of 0.725, which is satisfactory for first-application questionnaires. CONCLUSION: The BCSDTSD instrument was validated for assessment of behavioral changes related to the use of DT during SD.

RESUMO

BACKGROUND: Fluoride pollution is a global problem because of its high phytotoxicity. Fluoride is released in air, water and soil through industrial processes, where it damages various plant species. Ricinus communis is widely distributed in Brazil, India and China and has been extensively used as a phytoremediation species in heavy metal-contaminated soils. However, few studies regarding the effect of air pollutants on R. communis have been published, and no information about the exposure of this species to fluoride is available. Therefore, the aim of the present study was to investigate the effects of fluoride on R. communis morphoanatomical and physiological responses using simulated rainfall containing potassium fluoride (KF). METHODS: Young plants at approximately 10 days after emergence were treated daily with KF using simulated rainfall at 0, 1.5, 3.0 and 4.5 mg L-1, for 37 consecutive days. Chlorophyll a fluorescence, gas exchange, anatomical characteristics and fluoride accumulation in the roots and leaves were evaluated after this period. RESULTS: No visual or anatomical symptoms were observed for the first three treatments. Necrosis and chlorosis were visually evident after the 37th day of KF application at 4.5 mg L-1, followed by changes in parenchyma tissues, cell collapse and phenolic compound accumulation at the end of the experiment. No damage was observed in terms of photosynthetic photochemical and biochemical stages. Maintenance of physiological characteristics in the presence of fluoride accumulation in roots and leaves were shown to be important fluoride biomarkers. These characteristics suggest that R. communis is tolerant to 1.5 and 3.0 mg L-1 KF, and is anatomically sensitive at 4.5 mg L-1 KF.

RESUMO

OBJECTIVE: To determine the agreement between body self-image (based on the Stunkard figure rating scale) and nutritional status and to evaluate body satisfaction among the Khisêdjê indigenous people of Parque Indígena do Xingu (Xingu Indigenous Park). METHODS: A cross-sectional study involving 131 natives aged 20 and older. Data on body image, body mass index and waist circumference were collected. Kappa statistics, χ2 (p < 0.05), crude and adjusted prevalence ratios and Student's t-test were used for data analysis. RESULTS: The prevalence of overweight and obesity was respectively 42 and 5.3%. The percentage of satisfaction with body profile was 61.8% with no difference between the sexes. There was good agreement between actual and ideal self-image (p < 0.001), but poor agreement between actual and ideal self-image with nutritional status for both sexes. A higher prevalence of body dissatisfaction due to overweight was detected in individuals with central obesity and overweight. CONCLUSION: The results suggest that body self-image evaluated by the Stunkard silhouette scale has little applicability as an indicator of nutritional status among the indigenous Khisêdjê of Xingu Indigenous Park.

RESUMO

Lobomycosis is a rare granulomatous skin disease with a high prevalence in the Amazon region. The Kaiabi Indians are an especially affected group. We studied the current epidemiologic and clinical progression of lobomycosis among the Kaiabi in Brazil, from initial case reports in 1965 through 2019. A total of 60 lobomycosis cases had been reported among the Kaiabi, and we identified 3 new cases in our review. Of 550 cases of lobomycosis ever reported worldwide, 11.5% were among the Kaiabi. We note a high incidence among female Kaiabi and a precocious onset of disease in this indigenous population. Male Kaiabi frequently are infected with the multicentric form and women more frequently exhibit the localized form. Ulcerated lesions are observed more often in the multicentric form. The prevalence among this indigenous group could be explained by genetic susceptibility and lifestyle, which exposes them to a particular agent in the habitats in which they live.

RESUMO

Rapid growth in the oil industry has been accompanied concomitant increases in risks of spills or leaks triggered by natural or anthropogenic causes that cause soil changes and plant damage. Bio-scavenging and phytoremediation plants are important tools for identifying pollutants and mitigating environmental damage. The objective of this study was to evaluate the phytoremediation potential of Ricinus communis cultivated in soils contaminated with mineral oil, and to determine the possible visual, anatomical and physiological effects. R. communis seeds were pre-germinated in individual pots containing Red Latosol contaminated with Lubrax Essential SL (15W-40) mineral oil at concentrations of 0 (control), 5, 10, and 15 g kg-1. After exposure to treatments, emergency evaluations were performed, and after 45 days of cultivation, visual, morphoanatomical, physiological and oil removal effects were evaluated. There was no difference in emergence showed between treatments. Visual effects were characterized by necrosis and chlorosis formation in R. communis, evidenced on the 45th day of cultivation in all treatments tested, followed by parenchymal tissue alterations with collapsed cell formation and damage to photosynthesis with increasing doses. We found that R. communis removed up to 81% of hydrocarbons in soils, classifying it as potential phytoremediator of contaminated soils. The strong correlation between the variables suggests that R. communis can be used as an indicator of pollutant action.

RESUMO

RESUMO: Objetivos: Verificar a concordância entre autoimagem corporal (escala de silhuetas de Stunkard et al.) e estado nutricional e avaliar a satisfação corporal em indígenas khisêdjê do Parque Indígena do Xingu. Métodos: Estudo transversal que incluiu 131 indígenas khisêdjê, com 20 anos ou mais. Coletaram-se dados sobre imagem corporal, índice de massa corporal e perímetro da cintura. Foram utilizados a estatística kappa, o teste χ2 (p < 0,05), as razões de prevalências brutas e ajustadas e o teste t de Student. Resultados: As prevalências de sobrepeso e obesidade foram, respectivamente, 42 e 5,3%. A porcentagem de satisfação com o perfil corporal foi de 61,8%, sem diferença entre os sexos. Houve boa concordância entre autoimagem real e autoimagem ideal (p < 0,001), porém baixa concordância entre a autoimagem real e ideal e o estado nutricional para ambos os sexos. Maior prevalência de insatisfação corporal por excesso de peso foi detectada entre indivíduos com obesidade central e excesso de peso. Conclusão: Os resultados sugerem que a autoimagem corporal avaliada por meio da escala de silhuetas de Stunkard et al. tem pouca aplicabilidade como indicador do estado nutricional de indígenas khisêdjê do Parque Indígena do Xingu.

RESUMO

Resumo O objetivo deste artigo é apresentar e discutir a vulnerabilidade de povos indígenas em isolamento voluntário a epidemias decorrentes do contato com representantes de nossa sociedade e apontar os desafios para a assistência à saúde nas situações de contato iminente. A partir da experiência dos autores na atenção à saúde de comunidades indígenas isoladas e de contato recente e de informações existentes na literatura indigenista, são apresentados exemplos da alta mortalidade que incidiu sobre alguns povos indígenas em períodos posteriores à quebra de seu estado de isolamento. O artigo atualiza as informações existentes sobre povos indígenas isolados no Brasil, discute a política indigenista e as ameaças a que estão submetidos esses povos pelo avanço da invasão ilegal de seus territórios e alerta para a possibilidade de novos contatos entre esses grupos e a sociedade circundante no contexto atual de ataque aos direitos indígenas agravados pela epidemia de covid-19. Contextualizam-se a suscetibilidade dos povos indígenas isolados, a necessidade de preparação para futuras situações de contato e medidas para evitar o contágio quando ocorrer a quebra do estado de isolamento desses povos.


Abstract The purpose of this article is to present and discuss the vulnerability of indigenous people in voluntary isolation due to epidemics resulting from contact with representatives of our society and to point out the challenges for health care in situations of imminent contact. Based on the authors' experience in the health care of isolated and recently contacted indigenous communities and on information in the indigenous literature, examples of the high mortality that affected some indigenous peoples in periods after break of their isolation state are presented. The article updates the existing information on isolated indigenous peoples in Brazil, discusses the indigenous policy formulated for them, the threats to which they are subjected by the advance of the illegal invasion of their territories and alerts to the possibility of new contacts of these groups and the surrounding society, in current context of attack on indigenous rights aggravated by the COVID-19 pandemic. It contextualizes the susceptibility of isolated indigenous peoples, the need to be ready for future situations of contact and measures to avoid contagion when the isolation of these peoples is interrupted.

RESUMO

Native Cerrado plants are exposed to soils with low pH and high availability of Al. In this study, we measured the Al content in adult plants, and investigated the effects of various Al doses on germination and early development of Eugenia dysenterica plants. For germination tests, the seeds were soaked in Al solution and evaluated for twenty days in growth chambers. In a second experiment, young plants were cultivated in hydroponic systems with various Al concentrations to evaluate the morphological, anatomical and physiological characteristics of E. dysenterica. Anatomical changes and low germinative vigor were observed in seeds germinated in 600 and 800 µmol Al3+ L-1. In the hydroponic system, 200 µmol Al3+ L-1 stimulated root growth in young plants. The activity of antioxidant enzymes and the accumulation of phenolic compounds were greatest at the highest Al doses, preventing changes in gas exchange and chlorophyll a fluorescence. Starch grain accumulation was noted in plant cells exposed to 200 and 400 µmol Al3+ L-1. Adult E. dysenterica trees also accumulated Al in leaves, bark and seeds. These data suggest that E. dysenterica is tolerant to Al.

RESUMO

This paper analyses the impact of the Working with Traditional Midwives Program on the daily routine of a Krahô indigenous women group. This is an ethnographic study that mainly used observation and field diary as supporting tools. Other tools were timely interviews and secondary data. Fieldwork occurred between August 2015 and December 2016 and involved ten women of eight different villages. Results point to a disassociation between the Program's main objective, which is focused on appreciating and reviving midwives' knowledge and the daily village reality. Although the Program has targeted women who already work empirically on the birth setting, there was a generalized acknowledgement in villages that women "became midwives" after taking the course. Consequently, the lack of payment and the frustrated expectation that "government" would hire them, though never assumed, were interpreted as neglect.

Este artigo analisa o impacto do Programa Trabalhando com Parteiras Tradicionais no cotidiano de um grupo de mulheres indígenas Krahô. Trata-se de um estudo etnográfico que utilizou a observação e o diário de campo como suportes principais, além de entrevistas pontuais e dados secundários. O trabalho de campo ocorreu entre agosto de 2015 e dezembro de 2016 e envolveu dez mulheres de oito aldeias diferentes. Os resultados apontam uma desconexão entre o objetivo principal do Programa, centrado na valorização e no resgate do saber da parteira, e a realidade no cotidiano das aldeias. Muito embora o programa tenha como público-alvo mulheres que já atuam empiricamente no cenário do parto, houve o entendimento de que as mulheres "tornaram-se parteiras" após o curso. Por consequência, a falta de pagamento e a expectativa frustrada de contratação por parte do "governo", embora não previstas, foram interpretadas como descaso. Os resultados indicam um viés etnocentrado do Programa, focado na difusão do saber científico e na entrega de materiais fora da lógica de cuidado do grupo em análise. Estudos que avaliem o impacto das ações do Programa em outros contextos, inclusive não indígenas, podem contribuir para os ajustes necessários e a efetiva valorização do trabalho dessas mulheres.

Abstract This paper analyses the impact of the Working with Traditional Midwives Program on the daily routine of a Krahô indigenous women group. This is an ethnographic study that mainly used observation and field diary as supporting tools. Other tools were timely interviews and secondary data. Fieldwork occurred between August 2015 and December 2016 and involved ten women of eight different villages. Results point to a disassociation between the Program's main objective, which is focused on appreciating and reviving midwives' knowledge and the daily village reality. Although the Program has targeted women who already work empirically on the birth setting, there was a generalized acknowledgement in villages that women "became midwives" after taking the course. Consequently, the lack of payment and the frustrated expectation that "government" would hire them, though never assumed, were interpreted as neglect. Results reveal an ethnocentric bias of the Program, focused on disseminating scientific knowledge and delivering materials that deviate from the logic of the group under analysis. Studies that evaluate the impact of the Programs' actions in other contexts, including non-indigenous ones, may contribute to the necessary adjustments and the effective appreciation of these women's work.
