Pon1 and Sult1a1 Polymorphisms and Breast Cancer Among Young Women in Brazil.

Purpose: To investigate the association of genetic polymorphisms Gln192Arg and Leu55Met of Paraoxonase 1 (PON1) gene, and Arg213His of Sulfotransferase 1A1 (SUT1A1) gene with occurrence of breast cancer among young women living in Rio de Janeiro city. Methods: This is a hospital-based case-control study including 265 women aged 18-35 years, diagnosed with breast cancer at National Cancer Institute; and 277 controls in the same age group selected among women patients and companions of three general hospitals from Rio de Janeiro public health network. Polymorphisms genotyping was performed using the PCR-RFLP technique. Results: For PON1 gene, breast cancer women had a greater chance of being homozygote for Leu55Met polymorphism (ORadjusted = 1.42, 95% CI= 0.67-3.00, recessive model) and a lower chance of having at least one allele of Gln192Arg polymorphism (ORadjusted = 0.75, 95% CI = 0.50-1.13, dominant model), but without statistical significance. Accordingly, frequency of the haplotype Met55/Arg192 was lower among breast cancer women, but no statistically significant association was observed (ORadjusted = 0.85; 95% CI = 0.48-1.51). SULT1A1 His/His genotype was significantly associated with a protective effect for breast cancer (OR adjusted = 0.51, 95% CI = 0.28-0.91, recessive model). Conclusion: Arg213His polymorphism of SUT1A1 gene showed a protective effect against breast cancer among Brazilian young women. More studies with different designs are needed to understand the role of PON1 and SULT1A1 polymorphisms in breast cancer development in young Brazilian women.

Influence of non-pharmacological methods on duration of labor: a systematic review / A influência de métodos não farmacológicos na duração do parto: uma revisão sistemática

Abstract The article aims to verify the influence of MNFs on the duration of the birth process. A systematic review was carried out in the MEDLINE, Web of Science and LILACS databases, through a combination of terms that cover the topic addressed, from 1996 to 2021/April. The Excel spreadsheet was used to collect data to extract information regarding each selected article, in turn, data analysis included the evaluation and classification of quality, reliability and risk of bias, thus, the following tools were used: Cochrane RoB 2, Checklist and Newcastle-Ottawa Scale.

Salicylic Acid and Water Stress: Effects on Morphophysiology and Essential Oil Profile of Eryngium foetidum.

The exogenous application of bioregulators, such as salicylic acid (SA), has exhibited promising outcomes in alleviating drought stress. Nevertheless, its impact on culantro (Eryngium foetidum L.) remains unexplored. Thus, the aim of this study was to assess how SA impacts the growth, morphophysiology, and essential oil composition of culantro when subjected to drought. To achieve this, culantro plants were grown under three different watering regimes: well-watered, drought-stressed, and re-watered. Additionally, they were either treated with SA (100 µM) or left untreated, with water serving as the control. SA application did not mitigate the effects of drought in biomass production but increased biomass, leaf number, leaf area, and photosynthetic pigments under well-irrigated and re-watered conditions. After a drought period followed by re-watering, plants recovered membrane integrity independently of SA application. Water stress and the exogenous application of SA also modulated the profile of essential oils. This is the first report about SA and drought affecting growth and essential oil composition in culantro.

N-Methyl-(2S,4R)-trans-4-hydroxy-L-proline isolated Sideroxylon obtusifolium attenuates TPA-induced irritant contact dermatitis in mice.

Dermatitis is defined as a set of inflammatory diseases that affect the skin, with varied causes. Among the different types of dermatitis, contact dermatitis is the most prevalent. Although the current therapy is often effective, it is associated with adverse effects and the possibility of drug tolerance. N-Methyl-(2S, 4R)-trans-4-hydroxy-L-proline is a L-proline amino acid derivative found in the leaves of Sideroxylon obtusifolium, a species traditionally used to treat inflammatory diseases. The aim of this study was to investigate the topical anti-inflammatory effect of N-methyl-(2S, 4R)-trans-4-hydroxy-L-proline (NMP) in 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced irritant contact dermatitis in mice. Topically administered NMP, at doses of 0.03 - 0.50 mg/ear, reduced TPA-induced ear edema and neutrophil migration, as evidenced by low tissue myeloperoxidase activity and verified by histological examination. In addition, NMP (0.06 mg/ear) reduced tissue levels of pro-inflammatory cytokines (TNF-α, IL-6, IL-1ß, INF-γ and MCP-1) and of the anti-inflammatory cytokine IL-10, and reduced gene expression of TNF-α, IL-6 and IL-1ß increased by TPA. The data suggest that N-methyl-(2S, 4R)-trans-4-hydroxy-L-proline acts as a topical anti-inflammatory agent that decreases the expression of inflammatory cytokines, making it useful for the treatment of skin inflammation. Further investigations are necessary for its development as a therapeutic agent.

Water stress and exogenous carnitine on growth and essential oil profile of Eryngium foetidum L.

Water stress influences plant growth and metabolism. Carnitine, an amino acid involved in lipid metabolism, has been related to responses of plants to abiotic stresses, also modulating their metabolites. Culantro (Eryngium foetidum L.) is a perennial herb, rich in essential oils, native to Latin America, commonly used due to its culinary and medicinal properties. Here, we investigated the effect of exogenous carnitine on morphophysiology and the essential oil profile of culantro plants under water stress. For this, plants were grown under three water conditions: well-watered, drought stress, and re-watered; and sprayed with exogenous carnitine (100 µM) or water (control). Culantro growth was impaired by drought and enhanced by re-watering. Carnitine, in turn, did not reverse drought effects on growth, and impaired the growth of re-watered plants, also improving photosynthetic pigment content. Water conditions and carnitine application changed the essential oil profile of the plants. Drought and re-watering improved the production of eryngial, which was even increased with exogenous carnitine in re-watered plants. In addition, hydroquinone was only produced with the combination of re-watering and carnitine application. The application of exogenous carnitine can be a strategy to induce the production of essential oil compounds with cosmetic and pharmaceutical importance in culantro.

Effectiveness of mat pilates on fatigue in women with breast cancer submitted to adjuvant radiotherapy: randomized controlled clinical trial.

PURPOSE: This clinical trial aimed to evaluate the influence of Mat Pilates and time on the change in fatigue scores in women with breast cancer undergoing adjuvant radiotherapy (RT). Additionally, assess the adherence and adverse effects of Mat Pilates sessions and the association of the level of physical activity with severe fatigue symptoms. METHODS: One hundred fifty-six patients with non-metastatic breast cancer were randomized to usual care or supervised Mat Pilates exercise. Fatigue and physical activity level were measured at baseline, end of RT, 30 days, 3 and 6 months after RT. The generalized estimating equation (GEE) with intention to treat was applied. RESULTS: A significant difference in the fatigue mean between the end of RT and the baseline was found in patients of both groups. There was no adverse effect with the practice of Mat Pilates, and it was analyzed the reduction of the symptom pain after the end of RT in women of intervention group compared to the control. There was no significant effect on fatigue between the groups. Patients with severe fatigue after 3 and 6 months of RT reported a significantly lower level of physical activity in the last periods. CONCLUSION: Fatigue levels increased at the end of RT but returned to baseline values after 6 months. A lower level of physical activity was associated with severe fatigue symptoms. Mat Pilates was safe for these women and reduced the symptom pain after treatment, but it did not successfully reduce fatigue during adjuvant RT. REGISTRATION: NCT03333993.

Exposure to pesticides and breast cancer in the city of Petrópolis, Brazil.

To investigate the association between pesticide use and breast cancer. A hospital-based case-control study was conducted in Petrópolis city, Brazil. The study data were obtained through interviews, and the magnitude of the association between self-reported pesticide exposure and breast cancer was determined using unconditional logistic regression. A higher estimated risk for breast cancer was found in women exposed to pesticides for 10 or more years, where this association was not statistically significant after adjusting for potential confounders (OR = 1.40; 95% CI 0.85-2.49). A positive statistically significant association was found between breast cancer and higher educational level or previous use of hormone replacement therapy (HRT), whereas having had 2 or more pregnancies to term proved a protective factor. Further studies elucidating the contribution of pesticide exposure to the development of breast cancer are needed, given that current findings in the literature are conflicting.

Persistent organic pollutants in hospitalized individuals in the municipality of Petropolis, Brazil.

Persistent organic pollutants (POPs) are highly lipophilic and can accumulate and biomagnify in food chains. Characterized as a public health problem, exposure to these compounds enables the development of diseases like cancer, cardiovascular disease, diabetes, and obesity. The objective of this study was to estimate the plasma levels of organochlorine pesticides and PCBs in 151 samples (97 women; 54 men) in hospitalized individuals in Petropolis, Brazil. Individuals over 18 years of age and residing for at least 2 years in the mountainous region of the State of Rio de Janeiro, Brazil, participated in a cross-sectional study. Interviews using a structured questionnaire and blood samples to estimate plasma levels of persistent organic pollutants provided data. Gas chromatography coupled with triple quadrupole mass spectrometry provided the levels of organochlorine pesticides and PCBs. Compared to data present in the literature, the concentration of POPs was lower, and individuals from 55 to 64 years of age (3.28 ng mL-1) and women (2.52 ng mL-1) presented a higher average concentration of organochlorine pesticides; men (0.05 ng mL-1) also presented a high concentration of PCBs. This is the first Brazilian study to estimate the concentration of several POPs in a hospital-based sample that includes men and women, thus contributing to the characterization of our population regarding environmental exposures relevant to health.

Benefícios acidentários e previdenciários concedidos a portadores de câncer no Brasil, 2008-2014 / Accident and social security benefits granted to cancer patients in Brazil, 2008-2014

Resumo O objetivo deste artigo é descrever a distribuição do câncer entre os benefícios concedidos pelo Registro Geral da Previdência Social (RGPS), de 2008 a 2014, no Brasil. Estudo ecológico com dados cedidos pelo Instituto Nacional do Seguro Social (INSS). Determinou-se a proporção de benefícios acidentários (relacionados ao trabalho) e previdenciários (gerais) concedidos por câncer no Brasil, entre os benefícios concedidos por todas as causas e realizou-se uma análise espacial para avaliar a distribuição geográfica dessas proporções, tendo os estados brasileiros como unidade de análise. O câncer foi motivo de concessão de 533.438 benefícios (2,9% do total de benefícios concedidos por todas as causas), com predomínio do sexo feminino nos benefícios previdenciários (53,7%) e do sexo masculino nos benefícios acidentários (71,6%). As maiores proporções de benefícios previdenciários por câncer ocorreram nas regiões Norte e Centro-Oeste. Em 19 dos 26 estados brasileiros e no Distrito Federal não houve concessão de benefício acidentário por câncer. A análise das ocorrências de câncer que geraram concessões de benefícios do RGPS sugere uma desproporcionalidade da concessão de benefícios previdenciários em relação aos acidentários, principalmente nas regiões Norte, Nordeste e Sul do Brasil.

Abstract This article aims to describe the distribution of cancer among the benefits granted by the General Social Security Registry, from 2008 to 2014, in Brazil. Ecological study using data given by the National Social Security Institute. The proportion of accidental (work-related) and social security (general) benefits granted by cancer in Brazil was determined, among the benefits granted for all causes, and a spatial analysis was conducted to assess the geographical distribution of these proportions, with the states Brazilians as a unit of analysis. Cancer was the reason for granting 533,438 benefits (2.9% of the total benefits granted for all causes), with a predominance of females in social security benefits (53.7%) and males in accidental benefits (71.6 %). The highest proportions of social security benefits for cancer occurred in North and Midwest regions. In 19 of the 26 Brazilian states (including all states in the southern region) and in the Federal District, there was no granting of accident benefits for cancer. The analysis of the occurrences of cancer that generated benefit concessions suggests a disproportionality in granting of social security benefits in relation to accident workers, mainly in North, Northeast and South regions of Brazil.

Câncer segundo a Atividade Econômica na Região Sudeste do Brasil: Benefícios Concedidos pelo Regime Geral de Previdência Social / Cancer per Economic Activity at Brazil's Southeast Region: Benefits Granted by the Brazilian Social Security System / Cáncer según Actividad Económica en la Región Sudeste del Brasil: Beneficio Concedido por el Sistema General de Seguridad Social de Brasil

Introdução: Apesar da importância econômica da Região, ainda existem poucos estudos na literatura sobre o câncer ocupacional na Região Sudeste do Brasil. Objetivo: Comparar a distribuição do câncer entre os benefícios concedidos pelo Regime Geral da Previdência Social (RGPS), por ramo de atividade econômica do segurado, no período de 2008 a 2014, na Região Sudeste do Brasil. Método: Foram calculadas as proporções de benefícios acidentários (relacionados ao trabalho) e previdenciários (geral) concedidos por câncer, segundo o ramo de atividade econômica do segurado (bancário, comerciário, transporte e carga, ferroviário, industriário, marítimo, serviço público, rural e não preenchido). Resultados: O câncer representou 3,07% (271.086) dos benefícios concedidos por todas as causas. Os ramos de atividades comerciário e rural tiveram as maiores proporções de benefícios concedidos por câncer, em todos os Estados. Para ambos, as principais localizações de câncer que motivaram a concessão de benefícios previdenciários foram mama e próstata, e as outras neoplasias malignas da pele foram a principal localização para os benefícios acidentários. Conclusão: A desproporcionalidade entre o número de benefícios previdenciários e acidentários concedidos por câncer sugere erro em muitos benefícios, desfavorecendo os acidentários. O aprimoramento das anamneses do trabalhador pelo médico perito, com a utilização de documentos complementares, pode auxiliar no estabelecimento do nexo causal entre a atividade profissional e o câncer, concedendo benefícios acidentários quando houver esse nexo. Adicionalmente, ainda são necessárias estratégias de vigilância para subsidiar a implementação de ações de prevenção do câncer ocupacional na Região Sudeste do Brasil

Introduction: Despite the economic importance of the Region, there are still few studies in the literature about occupational cancer in Brazil's Southeast Region. Objective: Compare the distribution of cancer-related benefits granted by the Brazilian Social Security System (RGPS) by economic activity of the insured individual, between 2008 and 2014, at Brazil's Southeast Region. Method: The proportions of cancer-related accidental (work-related) and social security (general) benefits granted, according to the economic activity of the insured individual (bank cashier, salesperson, transport and freight worker, railway worker, industrial worker, sailor, public servant, rural worker, and blank) were calculated. Results: Cancer represented 3.07% (271,086) of the benefits granted for all causes. Commercial and rural activities showed the largest proportions of cancer-related benefits granted in all States. For both activities, breast and prostate cancers were the main locations that justified the approval of social security benefits, and other malignant skin neoplasms were the main locations for accidental benefits. Conclusion: The disproportionality between the number of cancer-related social security and accidental benefits granted suggests an error in many benefits, disfavoring accidental benefits. The improvement of the anamneses of the worker by the medical expert, with the use of additional documents, can aid the establishment of the causal link between the professional activity and the cancer developed, granting accidental benefits when this link exists. Moreover, surveillance strategies to boost the implementation of actions to prevent occupational cancer are still necessary at that Region

Introducción: A pesar de la importancia económica de la Región, todavía hay pocos estudios en la literatura sobre el cáncer ocupacional en la Región Sudeste del Brasil. Objetivo: Comparar la distribución del cáncer entre los beneficios otorgados por el Sistema General de Seguridad Social (RGPS), según la actividad económica del asegurado, de 2008 a 2014, en la Región Sudeste del Brasil. Método: Se calcularon las proporciones de los beneficios accidentales (laborales) y previsionales (generales) otorgados por cáncer, de acuerdo con la actividad económica del asegurado (bancaria, comercial, transporte y carga, ferroviaria, industrial, marítima, servicio público, rural y no llenado). Resultados: El cáncer representó el 3,07% (271.086) de los beneficios por todas las causas. Las actividades comerciales y rurales tuvieron las mayores proporciones de beneficios otorgados por cáncer, en todos los estados. Para ambos, las principales localizaciones de cáncer que motivaron el otorgamiento de los beneficios de la seguridad social fueron las de mama y próstata, y otras neoplasias malignas de la piel fueron la principal localización de los beneficios accidentales. Conclusión: La desproporción entre el número de beneficios de seguridad social y de accidentes otorgados por cáncer sugiere un error en muchos beneficios, desfavoreciendo los por accidentes. El perfeccionamiento de las anamnesis del trabajador por parte del perito médico, con el uso de documentos complementarios, puede ayudar a establecer el nexo de causalidad entre la actividad profesional y el cáncer, otorgando beneficios accidentales cuando exista dicho nexo. Además, todavía se necesitan estrategias de vigilancia para apoyar la implementación de acciones de prevención del cáncer ocupacional en la Región Sudeste del Brasil

Polimorfismo Genético TP53 Arg72Pro e Câncer de Mama em Mulheres Jovens: Estudo Caso-Controle no Brasil / TP53 Arg72Pro Genetic Polymorphism and Young Women with Breast Cancer: Case-Control Study in Brazil / Polimorfismo Genético TP53 Arg72Pro y Cáncer de Mama en Mujeres Jóvenes: Estudio de Casos y Controles en el Brasil

Introduction: Breast cancer is the most common cancer in women and incidence and mortality rates are increasing among young women worldwide, including Brazil. TP53 Arg72Pro polymorphism (rs1042522) has been associated with breast cancer, due to its important role in cell cycle that impacts the development of cancer. Objective: To determine the magnitude of the association between TP53 Arg72Pro polymorphism and breast cancer development in young Brazilian women. Method: Hospital-based case-control study conducted in Rio de Janeiro with 268 confirmed breast cancer cases and 277 controls with women enrolled among hospitalized patients without neoplastic diseases or their companions at three public hospitals. Results: The genotype frequency was 46.57% for Arg/Pro, 35.74% for Arg/Arg, and 17.69% for Pro/Pro among healthy controls and 41.04% for Arg/Pro, 46.64% for Arg/Arg, and 12.31% for Pro/Pro among breast cancer cases. The genotypes Pro/Pro (OR=0.46; 95% CI=0.27-0.80, in comparison with Arg/Arg genotype) and Pro allele in dominant model (OR=0.65; 95% CI=0.45-0.92, in comparison with Arg/Arg genotype) were statistically associated with a protective effect for breast cancer among young Brazilian women. Also, family history of breast or ovary cancer (OR=2.18; 95% CI=1.37-3.46) and tobacco use (OR=1.74; 95% CI=1.14-2.68) were statistically associated with breast cancer. Conclusion: Further studies are necessary to confirm that Arg72Pro polymorphism can be a protective factor for breast cancer development among young women, since ethnicity can influence genotypes frequencies and the risk of developing breast cancer

Introdução: O câncer de mama é o mais comum em mulheres e as taxas de incidência e mortalidade estão aumentando entre mulheres jovens em todo o mundo, inclusive no Brasil. O polimorfismo TP53 Arg72Pro (rs1042522) tem sido associado ao câncer de mama em razão do seu importante papel no ciclo celular que pode impactar o desenvolvimento do câncer. Objetivo: Determinar a magnitude da associação entre o polimorfismo TP53 Arg72Pro e o desenvolvimento de câncer de mama em mulheres jovens brasileiras. Método: Estudo caso-controle de base hospitalar realizado no Rio de Janeiro com 268 casos confirmados de câncer de mama e 277 controles com mulheres cadastradas entre pacientes internados sem doenças neoplásicas ou seus acompanhantes em três hospitais públicos. Resultados: A frequência genotípica foi de 46,57% para Arg/Pro, 35,74% para Arg/Arg e 17,69% para Pro/Pro entre controles saudáveis e 41,04% para Arg/Pro, 46,64% para Arg/ Arg e 12,31% para Pro /Pro entre os casos de câncer de mama. Os genótipos Pro/Pro (OR=0,46; IC 95%=0,27-0,80, em comparação ao genótipo Arg/ Arg) e o alelo Pro no modelo dominante (OR=0,65; IC 95%=0,45-0,92, em comparação com o genótipo Arg/Arg) foram estatisticamente associados a um efeito protetor para o câncer de mama em mulheres jovens brasileiras. Além disso, história familiar de câncer de mama ou ovário (OR=2,18; IC 95%=1,37-3,46) e tabagismo (OR=1,74; IC 95%=1,14-2,68) foi estatisticamente associada ao câncer de mama. Conclusão: Novos estudos são necessários para confirmar que o polimorfismo Arg72Pro pode ser um fator de proteção para o desenvolvimento de câncer de mama em mulheres jovens, uma vez que a etnia pode influenciar tanto as frequências desses genótipos quanto o risco de desenvolver câncer de mama

Positive attributes in elderly people with different degrees of depression: a study based on network analysis

Abstract Introduction Depression in aging may lead to loss of autonomy and worsening of comorbidities. Understanding how positive attributes contribute to healthier and happier aging has been one ofthe purposes of Positive Psychology. However, the literature still lacks studies that evaluate how depression in the elderly is related to constructs considered positive. Objective The present study aimed comparing scores of constructs of spiritual well-being, social support, selfesteem, life satisfaction, affection, optimism, and hope in the elderly with minimal, mild, moderate, and severe depression and healthy controls in order to investigate possible indirect and mediated relationships between positive constructs and depression. Methods A cross-sectional study was conducted with elderly, 62 of whom were diagnosed with different severity of Major Depression (DSM-V) (minimum, mild, moderate, and severe according to the Beck Depression Inventory - BDI) and 66 healthy controls matched by age, sex and schooling. The instruments used were adapted and validated versions of the Spirituality Self-Rating Scale, the Rosenberg Self-Esteem Scale, the Medical Outcomes Social Scale of Support, the Life Satisfaction Scale, the Positive and Negative Affect Schedule, the Revised Life Orientation Test, and the Adult Dispositional Hope Scale. After comparing the means of scores between groups, an analysis of normalized partial association networks was performed to investigate the direct and mediated relationships between depression and other evaluated constructs. Results Scores of spiritual well-being, social support, self-esteem, life satisfaction, positive affect, optimism, negative affects, and hope differed significantly between the control group and the degrees of depression (p < 0.001). The analysis of normalized partial association networks has shown that the relations of depression with the constructs of life satisfaction, self-esteem, and social support are mediated, while the constructs of dispositional hope, positive affect, spiritual well-being, and optimism are indirectly related to depression. The social class was also positively related to depression. Conclusion Depression in different degrees is associated with a reduction in the scores of instruments that evaluate positive attributes. The constructs directly associated with depression are spiritual well-being, optimism, positive affect, and dispositional hope. The others had mediated relationship. These results may contribute to the planning of future interventions for the prevention of depression among the elderly.

Medida do equilíbrio de decisões para redução do peso corporal entre pessoas com sobrepeso ou obesidade: uma revisão sistemática / Measuring the balance of decisions to reduce body weight among overweight or obesity people: a systematic review

Introdução: Abordagens comportamentais têm contribuído para a efetividade do tratamento da obesidade. A avaliação do equilíbrio de decisões (ED) para redução de peso, isto é, o equilíbrio entre prós e contras da mudança de comportamento, é estratégica no tratamento, contribuindo para a pactuação de estratégias para o enfrentamento dos desafios. É necessário, porém, utilizar instrumentos válidos para mensurar o ED. Objetivo: Avaliar a qualidade de instrumentos de avaliação do ED para redução do peso corporal visando qualificar o cuidado da pessoa com obesidade no Sistema Único de Saúde (SUS). Métodos: Realizou-se revisão sistemática da literatura sobre o desenvolvimento e a validação de instrumentos em sete bases de dados seguindo a metodologia Cosmin. Variações dos termos psicometria, obesidade e ED foram combinadas com operadores booleanos. Em duplicada e independentemente, duas pesquisadoras realizaram: extração de dados, avaliação da qualidade e síntese de evidências, sendo as divergências solucionadas por consenso. Esta revisão foi registrada na base internacional Prospero (CRD42020197797). Resultados: Identificaram-se cinco estudos, sendo que três realizaram a tradução e adaptação transcultural do mesmo instrumento. Todos os estudos apresentaram ED em duas dimensões (prós e contras), mas usaram métodos duvidosos ou inadequados, e a maioria apresentou evidências científicas de muito baixa qualidade. Conclusões: Os resultados não sustentaram o uso dos instrumentos existentes nem sua tradução e adaptação transcultural, sendo necessário o desenvolvimento de um novo instrumento. Este estudo, ao disponibilizar um instrumento válido para uso no SUS, poderá contribuir para qualificar o cuidado da pessoa com obesidade e deter o crescimento da obesidade no país.

Introduction: Behavioral strategies have been adding to the effectiveness of obesity treatment. And the assessment of the decisional balance (DB) for weight reduction, that is, the balance between expected losses and gains around the behavioral changes, is strategic for managing obesity. The DB assessment may contribute to the agreement on strategies to face the challenges of the treatment. But, there is a need to use a valid instrument to assess the DB. Objective: evaluate the quality of instruments assessing DB for weight reduction to qualify obesity management in the Sistema Único de Saúde ­ SUS (Unified Health System). Methods: A systematic review of studies about instrument development and/or validation was carried out on seven databases using the Cosmin methodology. Terms related to psychometrics, obesity, and DB were combined with Boolean operators to guide the search. Two researchers performed independently and in duplicate: data extraction, quality assessment, and evidence synthesis, and divergences were resolved by consensus. This review was registered in the international database Prospero (CRD42020197797). Results: Five studies were identified. Three of them reported translations and cross-cultural validity of the same instrument. All analyses presented DB in two dimensions (pros and cons, but used doubtful or inadequate methods. Most of the evidence was very low rate. Conclusions:The results did not support the instrument's use, translations, or cross-cultural adaptation. It is necessary to develop a new tool. By providing a valid instrument for use in SUS, this study could contribute to qualifying the care of people with obesity and stopping the growth of obesity in the country.

Hepatic and blood alterations in Lithobates catesbeianus tadpoles exposed to sulfamethoxazole and oxytetracycline.

In this study the effects of environmentally realistic concentrations of the antibiotics sulfamethoxazole (SMX) and oxytetracyclyne (OTC) on Lithobates catesbeianus tadpoles were evaluated, through the analyzes of the frequencies of micronucleus and nuclear abnormalities in erythrocytes, alterations in leucocytes, liver histopathology, and changes in hepatic esterase activities and oxidative stress biomarkers. The animals were exposed for 16 days at concentrations of 0 (control), 20, 90 and 460 ng L-1. No significant difference was found in the frequencies of micronucleus and nuclear abnormalities. The two highest concentrations of SMX and all concentrations of OTC caused a significant increase in the number of lymphocytes. A significant decrease in the number of neutrophils compared to the control group was observed for all concentrations tested of both antibiotics. Also, decrease in the activity of glutathione S-transferase and high histopathological severity scores, indicating liver damage, were found in tadpoles exposed to the two highest concentrations of SMX and all concentrations of OTC. The main changes in the liver histopathology were the presence of inflammatory infiltrate, melanomacrophages, vascular congestion, blood cells and eosinophils. Esterase activities were unchanged. Indeed, the two highest concentrations of OTC caused a reduction in the activities of superoxide dismutase and glucose 6-phosphate dehydrogenase, while the highest concentration inhibited the activity of glutathione peroxidase and increased protein carbonyl levels. These results evidences that environmentally realistic concentrations of SMX and OTC in aquatic environments are capable to significantly disrupt tadpoles' physiology, possibly affecting negatively their survival rate in natural environments.

Impact on fatigue of different types of physical exercise during adjuvant chemotherapy and radiotherapy in breast cancer: systematic review and meta-analysis.

BACKGROUND: Physical exercise in women with breast cancer has shown benefits in reducing fatigue levels during adjuvant radiotherapy and chemotherapy. However, it is not well understood which type of exercise is more effective. OBJECTIVE: Assess the impact of different types of physical exercises on fatigue and which is the most effective in reducing this adverse effect during adjuvant treatment in breast cancer. METHODS: The inclusion criteria were randomized clinical trials of physical exercise in women diagnosed with breast cancer in stages I to IV, above 18 years, evaluating fatigue using validated questionnaires. The meta-analysis pooled results by standardized mean difference (SMD). RESULTS: A total of 20 randomized clinical trials involving 1793 participants revealed that the practice of physical exercise was statistically effective in reducing fatigue (SMD = - 0.46; 95% CI: - 0.66, - 0.27). Our analysis of subgroups suggests that the supervised combination of resistance training (RT) with aerobic training (AT) is the most effective physical exercise to reduce fatigue (SMD = - 1.13; 95% CI: - 2.09, - 0.17). The supervised RT was more effective (SMD = - 0.30; 95% CI: - 0.46, - 0.15) than supervised AT or mind-body techniques. It was observed that only during chemotherapy, women with breast cancer in the intervention groups showed a significant reduction in fatigue (SMD = - 0.38; 95% CI: - 0.55 to - 0.20). CONCLUSION: Physical exercise during adjuvant chemotherapy and/or radiotherapy in women with breast cancer can be considered beneficial in reducing fatigue, especially for women undergoing chemotherapy and for supervised training of resistance or combined RT and AT.

Objetivo: Os ácidos graxos essenciais (AGE) ômega-3 dos tipos ácido eicosapentaenoico (EPA) e ácido docosa-hexaenoico (DHA), são benéficos para o sistema nervoso central (SNC) - com estudos demonstrando seu papel na mielinização, formação de sinapses, além da relação de sua deficiência com o desenvolvimento de patologias neurológicas e psiquiátricas. Portanto, o presente trabalho objetiva avaliar sistematicamente os efeitos da ingestão de EPA/DHA no SNC de humanos em diferentes faixas etárias e estados de saúde neurológica e psiquiátrica. Metodologia: Foi adotado o método PRISMA, a busca por estudos foi realizada na base de dados científicos Medline, sendo incluídos artigos publicados entre 2010-2021, publicados em língua inglesa, ensaios clínicos aleatórios (randomizados), e estudos observacionais. Resultados:11 artigos foram selecionados e, em seguida, categorizados por temas. No desenvolvimento neuropsicomotor infantil, observou-se, com a suplementação, benefícios na aquisição da linguagem e obtenção de escores levemente melhores em testes neurológicos. Em adultos saudáveis, houve indícios de aumento na eficácia do processamento neural. No TDAH em crianças, melhores resultados em testes de atenção. Em indivíduos com esquizofrenia, houve menor perda da espessura cortical. Em idosos com déficit de memória ou doença de Alzheimer, maior oxigenação cerebral, menos inflamação e desaceleração da perda de massa cerebral. Conclusão: Constata-se, pela análise dos estudos, que os AGs EPA/DHA beneficiam o SNC por meio de efeitos no neurodesenvolvimento, função cognitiva, prevenção de doenças e como estratégia terapêutica adjuvante.

Objective: The omega-3 essential fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are beneficial to the central nervous system (CNS), with studies demonstrating their role in myelination and synaptogenesis. Furthermore, its deficiency was correlated with the development of neurological and psychiatric pathologies. Therefore, the present work aims to systematically evaluate the effects of EPA/DHA ingestion on the CNS of humans in different age groups and neurological and psychiatric health status. Methodology: This study was conducted observing the PRISMA method; the search for studies was performed in the scientific database Medline. The inclusion criteria were articles published between 2010-2021, published in English, randomized clinical trials with humans, and observational studies. Results: 1 1 articles were selected and then categorized by topic. It was observed that in children's neuropsychomotor development the EPA/DHA supplementation benefited language acquisition and provided slightly better scores in neurological tests. In healthy adults, there was found evidence of an increase in the effectiveness of neural processing. In children with ADHD, the consumption of EPA/DHA was linked with better scores on tests of attention. In individuals with schizophrenia, there was less loss of cortical thickness. In older adults with memory deficits or Alzheimer's disease, results such as an increase in brain oxygenation, less inflammation, and slower brain mass loss were found. Conclusion: From the analysis of the studies, it appears that the ingestion of EPA/DHA benefits the CNS through effects on neurodevelopment, cognitive function, disease prevention, and as an adjuvant therapeutic strategy.

Introdução: Traumatismos dentários são considerados problema de saúde pública, sendo a segunda maior demanda de urgências odontológicas, tendo sua maior ocorrência em ambiente escolar, atribuindo aos professores a responsabilidade de adotar as primeiras condutas. Objetivo: Avaliar o conhecimento de acadêmicos do último ano dos cursos de educação física e pedagogia da Universidade Federal do Espírito Santo frente aos traumatismos dentários. Material e método: Estudo descritivo transversal onde foram aplicados 106 questionários, sendo 55 no curso de pedagogia e 51 no curso de educação física envolvendo dados sociodemográficos e conhecimento sobre injúrias dentárias. A análise estatística foi feita por meio do pacote estatístico SPSS 20. Resultado: 98,1% dos entrevistados não tiveram treinamento sobre traumatismos, 92,5% não se julgam aptos a prestar socorro diante de um trauma, mas consideram importante (55,7%). Sobre a avulsão dentária a maioria respondeu que não reimplantaria e não possuem conhecimento sobre o tempo apropriado bem como é feito o armazenamento/transporte do elemento dentário. Conclusão: Os futuros docentes demonstraram despreparo e conhecimento deficiente diante das condutas em traumatismos, favorecendo prognósticos desfavoráveis, impactando negativamente na qualidade de vida das vítimas, no tocante a aspectos estéticos, funcionais e psicológicos. Evidencia-se, portanto, necessidade de treinamento e capacitação destes durante sua formação profissional

Introduction: Dental trauma is considered a public health problem, being the second most prominent dental emergency, whose greatest occurrence is in schools, assigning teachers the responsibility of administering first aid. Objective: To evaluate the knowledge of dental trauma among final-year's students of pedagogy and physical education courses at the Federal University of Espírito Santo. Material and method: A cross-sectional descriptive study was applied. A total of 106 questionnaires were answered by 55 students from the physical education course and 51, from the pedagogy course; comprised of ciodemographic data and knowledge of dental injuries. Statistical analysis was done using the statistical package SPSS 20. Result: 98.1% of the interviewees had no training on trauma, 92.5% considered themselves incapable of providing help when facing trauma, but considered the ability important (55.7%). When asked about tooth avulsion, most of them answered that they would not reimplant the tooth, were not aware of the appropriate time window to do so, or how the storage/transportation of the dental element was to be done. Conclusion: These future teachers showed unpreparedness and deficient knowledge Evaluation of the knowledge regarding trauma treatment procedures, favoring unfavorable prognoses which would negatively impact the quality of life of the victims in terms of aesthetic, functional and psychological aspects. Therefore, the need for dental trauma education during their professional training is evident

Effect of systemic photobiomodulation in the course of acute lung injury in rats.

Acute lung injury (ALI) is a severe, multifactorial lung pathology characterized by diffuse alveolar injury, inflammatory cell infiltration, alveolar epithelial barrier rupture, alveolar edema, and impaired pulmonary gas exchange, with a high rate of mortality; and sepsis is its most common cause. The mechanisms underlying ALI due to systemic inflammation were investigated experimentally by systemic lipopolysaccharide (LPS) administration. Photobiomodulation (PBM) has been showing good results for several inflammatory diseases, but there are not enough studies to support the real benefits of its use, especially systemically. Considering that ALI is a pathology with high morbidity and mortality, we studied the effect of systemic PBM with red light-emitting diode (LED) (wavelength 660 nm; potency 100 mW; energy density 5 J/cm; total energy 15 J; time 150 s) in the management of inflammatory parameters of this disease. For this, 54 male Wistar rats were submitted to ALI by LPS injection (IP) and treated or not with PBM systemically in the tail 2 and 6 h after LPS injection. Data were analyzed by one-way ANOVA followed by Student's Newman-Keuls. Our results point to the beneficial effects of systemic PBM on the LPS-induced ALI, as it reduced the number of neutrophils recruited into the bronchoalveolar lavage, myeloperoxidase activity, and also reduced interleukins (IL) 1ß, IL-6, and IL-17 in the lung. Even considering the promising results, we highlight the importance of further studies to understand the mechanisms involved, and especially the dosimetry, so that in near future, we can apply this knowledge in clinical practice.
