Abstract This ecological, time-trend study examined rates of homicide against women residing in Brazil, by state and race/colour, from 2016 to 2020, by performing. Multiple analysis by regression model on longitudinal data. During the study period, 20,405 homicides of women were recorded in Brazil. Standardised homicides rates were higher among black women (6.1/100,000) than among white women (3.4/100,000). From 2016 to 2020, rates decreased 25.2%, from 4.7 deaths per 100,000 women in 2016 to 3.5 in 2020, with a statistically significant downward trend among both black and white women. Statistically significant inverse relationships were found between female homicide rates and HDI, illiteracy rate and proportion of ill-defined causes. The average homicide rate decreased in 2019 and 2020, as compared with 2016. Despite the decreasing time trend in homicide rates for both black and white women, they differed substantially by race, with worse outcomes for black women. ecological timetrend Brazil racecolour race colour race/colour 201 2020 performing data period 20405 20 405 20,40 6.1/100,000 61100000 6 1 100 000 (6.1/100,000 3.4/100,000. 34100000 3.4/100,000 . 3 4 (3.4/100,000) 252 25 2 25.2% 47 7 4. 100000 100,00 35 5 3.

Resumo O objetivo deste estudo é avaliar as taxas de homicídios contra mulheres residentes no Brasil, segundo unidades da federação e raça/cor, no período de 2016 a 2020. Trata-se de um estudo ecológico de tendência temporal. Foi realizada análise múltipla adotando-se modelo de regressão para dados longitudinais. No período, ocorreram no Brasil 20.405 homicídios de mulheres e as taxas padronizadas mostraram que as mulheres negras (6,1/100.000) apresentaram as maiores taxas, em comparação às brancas (3,4/100.000). O Brasil apresentou queda de 25,2% de 2016 a 2020. A taxa de homicídio variou de 4,7 mortes por 100 mil mulheres em 2016 para 3,5 em 2020, mas a tendência decrescente e estatisticamente significante foi observada nas taxas de mulheres negras e brancas. As variáveis IDH, taxa de analfabetismo e proporção de causas mal definidas apresentaram uma relação inversa e estatisticamente significante com as taxas de homicídio de mulheres. Nos anos de 2019 e 2020 houve uma diminuição da taxa média de homicídio em relação ao ano de 2016. Apesar do decrescimento na evolução temporal das taxas para negras e brancas, houve diferenças raciais importantes nos homicídios de mulheres, com piores resultados para as mulheres negras. raçacor raça cor raça/cor 201 Tratase Trata se adotandose adotando longitudinais 20405 20 405 20.40 6,1/100.000 61100000 6 1 000 (6,1/100.000 3,4/100.000. 34100000 3,4/100.000 . 3 4 (3,4/100.000) 252 25 2 25,2 47 7 4, 10 35 5 3, IDH 202 2040 40 20.4 6,1/100.00 6110000 00 (6,1/100.00 3410000 3,4/100.00 (3,4/100.000 25, 204 20. 6,1/100.0 611000 0 (6,1/100.0 341000 3,4/100.0 (3,4/100.00 6,1/100. 61100 (6,1/100. 34100 3,4/100.

Abstract Mortality caused by the COVID-19 pandemic has impacted indicators of Years of Potential Life Lost (YPLL) worldwide. This study aimed to estimate the YPLL due to mortality caused by COVID-19, according to sex, age group, and race/color in Brazil, from March 2020 to December 2021. Deaths caused by COVID-19 were characterized, in which the rates and ratios of standardized YPLL rates, the average number of years of potential life lost (ANYPLL), and the average age at death (AAD) were estimated and compared. Overall, 13,776,969.50 potential years of life were lost, which resulted in an average loss of 22.5 potential years not lived. A greater loss of potential years of life was identified in men (58.12%) and in the age groups from 0 to 59 years in the black (58.92%) and indigenous (63.35%) populations, while in the age groups of 60 years and over, a greater loss of YPLL was observed in the white (45.89%) and yellow (53.22%) populations. Women recorded the highest ADD, with the exception of indigenous women. White men (1.63), brown men (1.59), and black men (1.61) had the highest rates when compared to white women. Although COVID-19 has a greater impact on the elderly, it was the black and indigenous populations under the age of 60 who had the greatest loss of potential years of life.

Resumo O objetivo deste artigo é analisar a distribuição espacial da vacina contra Hepatite B (VCHB) de gestantes. Estudo transversal, realizado com 266 puérperas. O registro da VCHB foi obtido por meio da caderneta de pré-natal. Para a detecção do cluster de risco para presença de registro ou ausência de VCHB foi utilizada a técnica de varredura espacial. Posteriormente a esta identificação do cluster, procedeu-se à comparação das variáveis individuais e ambientais entre as Áreas de Abrangência da Unidade Básica de Saúde (AA-UBS). A prevalência média de não VCHB foi de 88,34%. A análise de varredura espacial Scan observou-se um cluster de alta prevalência de puérperas que apresentava o registro da VCHB em suas cadernetas. Análises comparativas demonstraram que trabalho remunerado e o número de consultas realizadas no pré-natal estão associados positivamente a VCHB. Este trabalho suscita uma reflexão de possíveis disparidades com as demais AA-UBS, além da perspectiva a nível ambiental. Ressalta-se que a situação vacinal sofre influência não somente de fatores intrínsecos aos indivíduos, entretanto, nesse estudo, os resultados apontam que as variáveis individuais são majoritariamente mandatórias na decisão das gestantes em vacinarem.

Abstract The objective of this article is to analyze the spatial distribution of Hepatitis B vaccine (HBVAC) of pregnant women. This is a cross-sectional study carried with 266 puerperae. The HBVAC record was obtained through the prenatal care booklet. The spatial scanning technique was used to detect a cluster of risk for the presence or absence of an HBVAC record. After this cluster identification, the individual and environmental variables were compared between the Coverage Areas of Basic Health Units (CAs-BHUs). The mean prevalence of non-HBVAC was 88.34%. Scan spatial scan analysis observed a cluster of a high prevalence of puerperae with a HBVAC record. Comparative analyses have shown that paid work and the number of prenatal visits are positively associated with an HBVAC record. Given the above, this work brings a reflection on possible disparities with other CAs-BHUs, besides the influence of the environmental perspective. It should be emphasized that the vaccination situation is influenced not only by factors intrinsic to the individuals. However, in this study, the results indicate that individual variables are predominantly mandatory in the decision of HBVAC uptake among pregnant women.

SUMMARY The objective of the present study was to analyze the effects of four different training models, two aerobic and two anaerobic models, in relation to muscular hypertrophy, by means of morphometric analysis of the muscle cells of the soleus muscle and the extensor digitorum longus muscle (EDL). The animals were divided into five groups, control (C), aerobic training in swimming (ATS), resistance training in water (RTW), aerobic training on a treadmill (ATT), and resistance training in climbing (RTC). The aerobic training was performed at 70 % of the anaerobic threshold for 30 minutes, while the RTW was composed of 3 series of 10 jumps, and the RTC 4 series of climbs, both at 80 % of the maximum load. All training protocols were performed for a total period of 4 weeks, 3 times per week. The diameters of the muscle cells were measured by means of histological slides of the EDL and soleus muscles. For the EDL muscle, there was no difference between the ATS and ATT aerobic training models (p = 0.20). However, the RTW presented greater hypertrophy when compared to the RTC (p <0.01). Regarding the soleus muscle, the ATS was responsible for generating greater hypertrophy than the ATT (p <0.01). In addition, the RTC was more efficient at producing hypertrophy than the RTW (p <0.01). In this way, it was concluded that exercise adaptation was according to exercise type, aerobic or anaerobic, and not to the modality used.

RESUMEN El objetivo del estudio fue analizar los efectos de cuatro diferentes modelos de entrenamiento, dos aeróbicos y dos anaeróbicos en la hipertrofia muscular en ratas, a través del análisis morfométrico de las células musculares de los músculos sóleo y extensor largo de los dedos (ELD). Los animales fueran divididos en cinco grupos: control (C), entrenamiento aeróbico en natación (TAN), entrenamiento resistido en medio acuático (TRA), entrenamiento resistido en escalada (TRE) y entrenamiento aeróbico en estera rodante (TRE). Los entrenamientos aeróbicos fueron realizados a 70 % del umbral anaeróbico, durante 30 minutos, en cuanto los TRA fueron realizados por 3 series de 10 saltos y el TRE, 4 series de escaladas, ambos a la intensidad de 80 % de la carga máxima. Todos los protocolos de entrenamientos fueron realizados tres veces a la semana por un período de 4 semanas. Fueron demarcados los diámetros de las células musculares de los músculos ELD y sóleo por medio de láminas histológicas. En el músculo ELD no se pudo observar diferencia entre los modelos de entrenamiento aeróbico TAN y TAE (p=0,20). Además, el TRA demostró mayor hipertrofia comparado al TRE (p<0,01). Con relación al músculo sóleo, el TAN fue responsable de generar mayor hipertrofia respecto al TRA (p<0,01). De este modo es posible concluir que la adaptación depende del tipo de ejercicio, aeróbico o anaeróbico, y no en función de la modalidad utilizada.

ABSTRACT Schinus terebinthifolius Raddi, Anacardiaceae, native to Brazil, is referred to as "pimento-rosa" and is used to treat inflammatory disease in folk medicine. Studies have reported important pharmacological properties, but these effects have still not been fully exploited. This study reports that the crude extract and isolated compounds of S. terebinthifolius (leaves) have in vitro antioxidant, antiproliferative, and in vivo anti-inflammatory activities. The samples were evaluated for antioxidant activity using 2, 2-diphenyl-1-picrylhydrazyl, β-carotene/linoleic acid and 2,2′-azino-bis-(3-ethylbenzothiazoline)-6-sulphonic acid reagents. The anti-inflammatory effects were assayed against a carrageenan-induced paw oedema model in mice to test doses of 10, 100 and 300 mg/kg at different time points in addition to myeloperoxidase activity analysis. The antiproliferative activity was evaluated using ten human tumour cell lines. Two derivatives of gallic acid and four flavonoids were isolated and exhibited considerable antioxidant activity. The extract and its compounds showed selectivity towards ovarian cancer cells, with growth inhibitory activity values ranging from 1.9 to 6.5 µg/ml. Sample extracts and methyl gallate significantly inhibited carrageenan-induced oedema in the mice paw oedema experimental model. The calculated topological polar surface area for methyl gallate (86.98 Å2) showed good intestinal absorption. The effects reported herein are be related to the presence of flavonoids and the galloyl phenolic derivative content.

Resumo Fundamento: Insuficiência cardíaca direita apresenta grande morbimortalidade e pode ser causada por hipertensão arterial pulmonar. Um método diferenciado e inovador utilizado em avaliações histológicas é a dimensão fractal, que permite a caracterização de estruturas irregulares e complexas e pode quantificar alterações estruturais dos tecidos. Objetivo: Avaliar a utilização do método da dimensão fractal nos cardiomiócitos de ratos com hipertensão arterial pulmonar induzida por monocrotalina, associada com análise histológica e funcional. Métodos: Ratos Wistar machos foram divididos em 2 grupos: controle (C; n = 8) e hipertensão arterial pulmonar induzida por monocrotalina (M; n = 8). Após 5 semanas da indução da hipertensão arterial pulmonar pela monocrotalina, foi realizado ecocardiograma. Os animais foram eutanasiados, o coração dissecado e os ventrículos pesados para avaliação dos parâmetros anatômicos. Lâminas histológicas foram confeccionadas, coradas com hematoxilina/eosina para análise da dimensão fractal, realizada pelo método box-counting . Inicialmente foi testada a normalidade dos dados (teste Shapiro Wilk) e a comparação entre os grupos foi por meio do teste t de Student não pareado ou teste de Mann Whitney (p < 0,05). Resultados: Maiores valores da dimensão fractal foram observados no grupo M em comparação ao C (1,43 ± 0,06 vs. 1,37 ± 0,04; p < 0,05). O ecocardiograma apontou menores valores no grupo M para velocidade máxima pulmonar, tempo de aceleração pulmonar e tempo de ejeção, sugerindo piora funcional nesses animais, que também apresentaram hipertrofia cardíaca. Conclusão: As alterações observadas comprovam a disfunção cardíaca induzida pela hipertensão arterial pulmonar e apontam que a dimensão fractal é um método eficaz para avaliar alterações morfológicas cardíacas induzidas pela disfunção ventricular.

Abstract Background: Right-sided heart failure has high morbidity and mortality, and may be caused by pulmonary arterial hypertension. Fractal dimension is a differentiated and innovative method used in histological evaluations that allows the characterization of irregular and complex structures and the quantification of structural tissue changes. Objective: To assess the use of fractal dimension in cardiomyocytes of rats with monocrotaline-induced pulmonary arterial hypertension, in addition to providing histological and functional analysis. Methods: Male Wistar rats were divided into 2 groups: control (C; n = 8) and monocrotaline-induced pulmonary arterial hypertension (M; n = 8). Five weeks after pulmonary arterial hypertension induction with monocrotaline, echocardiography was performed and the animals were euthanized. The heart was dissected, the ventricles weighed to assess anatomical parameters, and histological slides were prepared and stained with hematoxylin/eosin for fractal dimension analysis, performed using box-counting method. Data normality was tested (Shapiro-Wilk test), and the groups were compared with non-paired Student t test or Mann Whitney test (p < 0.05). Results: Higher fractal dimension values were observed in group M as compared to group C (1.39 ± 0.05 vs. 1.37 ± 0.04; p < 0.05). Echocardiography showed lower pulmonary artery flow velocity, pulmonary acceleration time and ejection time values in group M, suggesting function worsening in those animals. Conclusion: The changes observed confirm pulmonary-arterial-hypertension-induced cardiac dysfunction, and point to fractal dimension as an effective method to evaluate cardiac morphological changes induced by ventricular dysfunction.

OBJETIVO: Este estudo investigou alterações de curto prazo na composição corporal, na força de preensão palmar e na presença de linfedema em mulheres submetidas à cirurgia do câncer de mama. MÉTODOS: Noventa e cinco mulheres participaram de um estudo transversal, sendo divididas em dois grupos: Controle (n=46), mulheres saudáveis, e Experimental (n=49), mulheres seis meses após cirurgia do câncer de mama. O Grupo Experimental foi subdividido em mastectomia total direita (RTM, n=15), mastectomia total esquerda (LTM, n=11), quadrantectomia direita (RQ, n=13) e quadrantectomia esquerda (LQ, n=10). Também foi redistribuído entre mulheres com presença (n=10) ou ausência (n=39) de linfedema. Foram avaliadas a presença de linfedema, a força de preensão palmar e a composição corporal. RESULTADOS: A massa magra de tronco e a força de preensão palmar estavam diminuídas no Grupo Experimental. Massa magra total estava aumentada na LTM comparada à RTM ou LQ. Força de preensão palmar esquerda na LTM estava diminuída comparada à RTM e RQ e em LQ comparada à RTM e RQ. Finalmente, massa magra total, magra e gorda de tronco e massa magra de braço esquerdo e direito estavam aumentadas em mulheres com linfedema. CONCLUSÕES: Sobreviventes do câncer de mama possuem alterações na composição corporal e na força de preensão palmar seis meses após a cirurgia, porém a interação entre o tipo de cirurgia e seu impacto não está clara. Além disso, mulheres que desenvolveram linfedema neste período mostraram alterações mais significantes na composição corporal, mas que não foram suficientes para causar prejuízo na força de preensão palmar.

PURPOSE: This study investigated short-term changes in body composition, handgrip strength, and presence of lymphedema in women who underwent breast cancer surgery. METHODS: Ninety-five women participated in a cross-sectional study, divided into two groups: Control (n=46), with healthy women, and Experimental (n=49), with women six months after breast cancer surgery . The Experimental Group was subdivided into right total mastectomy (RTM, n=15), left total mastectomy (LTM, n=11), right quadrant (RQ, n=13), and left quadrant (LQ, n=10). It was also redistributed among women with presence (n=10) or absence (n=39) of lymphedema. Presence of lymphedema, handgrip strength, and body composition were assessed. RESULTS: Trunk lean mass and handgrip strength were decreased in the Experimental Group. Total lean mass was increased in the LTM compared to RTM or LQ. Left handgrip strength in LTM was decreased compared to RTM and RQ and in LQ compared to RTM and RQ. Finally, total lean mass, trunk fat mass, trunk lean mass, right and left arm lean mass were increased in women with lymphedema. CONCLUSIONS: Breast cancer survivors have changes in their body composition and in handgrip strength six months after surgery; however, the interaction between the type of surgery and its impact is unclear. Furthermore, women who developed lymphedema in this period showed more significant changes in the body composition, but they were not enough to cause impairment in handgrip strength.

The present study was carried out to evaluate the effect of statins associated with physical exercise (PE) in liver cells in dyslipidemic rats through cariometry. The animals were divided into six groups: animals subjected to a hypercholesterolemic diet (HD), simvastatin, with (G1) and without (G2) physical exercise (PE); HD submitted (G3) or not (G4) to PE, and commercial food diet (F) with (G5) and without (G6) PE. Histological analysis of the liver was performed by staining the slides with hematoxylin and eosin. The cariometric study included measuring the major and minor diameters of the hepatocytes nuclei. The Shapiro-Wilk test was also performed. To determine the differences among the groups, the Kruskal-Wallis Test with Dunn's post-test were conducted. The significance level was set at 5%. No difference was found in the hepatocytes nuclei between G5 and G6. When these groups were related with G3 and G4, reduced nuclei were observed. There was no difference between G1 and G6. The comparison between G6 and G2 showed that the nuclei in G2 were smaller. No difference was detected between G5 and G1. Changes were observed in the nuclei shape in G2 in comparison to G1. Considering G2 and G3, a decrease in the size of nuclei was observed in G3. On the other hand, G2 showed changes in shape in the comparative analysis with G4. The size and shape of G1 nuclei were larger than G3 as well as changes in shape were observed when compared to G4. G4 showed smaller nuclei than G3. Therefore, F, associated or not with the practice of PE, does not alter the size and shape of the hepatocytes nuclei; HD combined with sedentarism influences changes in the morphometric parameters of hepatocytes; and the association of simvastatin and PE seems to protect the hepatocytes nuclei with regard to HD.

Fitobezoares são estruturas formadas pela agregação de fibras, principalmente vegetais, no trato digestivo de ruminantes, ocasionando obstruções intestinais que podem levar o animal à morte. Informações sobre a formação desse aglomerado ainda são escassas. Neste estudo, são identificados os principais componentes de fitobezoares bovinos, e descrita as estruturas anatômicas das folhas de três espécies de Stylosanthes SW.: S.capitata Vogel, S. macrocephala M. B. Ferreira & S. Costa, S. guianensis var. vulgaris M.B. Ferreira & Sousa Costa cv. 'Mineirão' e S. guianensis (Aubl.) Sw. As plantas selecionadas são utilizadas na dieta do gado e potenciais formadoras do fitobezoar. Os fitobezoares foram fragmentados para análise de sua composição e analisados seguindo-se as técnicas da anatomia vegetal. As fibras e cristais encontrados em fitobezoares são similares aos observados nos feixes esclerenquimáticos presentes nos folíolos das espécies de Stylosanthes avaliadas. Nossos resultados apontam diferenças na abundância de fibras nos folíolos de cada espécie. S. macrocephala é a variedade que sugere maior potencial para formação de fitobezoares no trato digestivo de animais que se alimentam dessa leguminosa, devido a abundância de fibras e cristais presentes na folha. Os feixes esclerenquimáticos, idioblastos e a abundância de cristais de oxalato de cálcio nas espécies Stylosanthes podem potencializar a formação de fitobezoares em ruminantes, em especial quando essas leguminosas são consumidas em excesso.

Phytobezoars are structures formed by the aggregation of primarily plant fibers in the digestive tract of ruminants, causing intestinal obstruction that can lead to the death of an animal. Information about the formation of these clusters is scarce. This study identified the main components of bovine phytobezoars and described the leaf anatomy of three species and one variety of Stylosanthes SW.: S.capitata Vogel, S. macrocephala B. Ferreira & S. Costa, S. guianensis var. vulgaris M.B. & Sousa Ferreira Costa cv. 'Mineirão' and S. guianensis (Aubl.) Sw. These plants are used as feed for livestock and probably contribute to the formation of phytobezoars. The phytobezoars were fragmented for analysis of their internal composition and were studied according to plant anatomy techniques. The fibers and crystals found in phytobezoars were similar to the sclerenchyma fiber bundles found in Stylosanthes. The comparative analysis of Stylosanthes showed differences in the abundance of fibers in the leaflets of each species. S. macrocephala is the variety that may have the highest potential for formation of phytobezoars in the digestive tract of animals because there was an abundance of fibers and crystals present in the leaf. The sclerenchyma bundles, idioblasts, and the abundance of calcium oxalate crystals in Stylosanthes species may potentiate the formation of phytobezoars in ruminants, particularly when these legumes are consumed in excess.

A discriminação racial pode influenciar o funcionamento dos serviços de saúde e as relações entre profissionais e usuários(as) e pode ser reproduzida, imperceptivelmente, através do modo como as pessoas do entorno são tratadas. Este estudo teve como objetivo descrever a percepção de mulheres acerca da discriminação racial nas práticas de cuidado em saúde reprodutiva. Trata-se de um estudo exploratório-descritivo, com abordagem qualitativa. As informações foram coletadas numa Unidade Básica de Saúde de Salvador-BA, em 2010, por meio de entrevista semiestruturada, realizada com 25 mulheres. Para análise dos discursos utilizou-se a técnica de análise temática. A análise revelou situações de discriminação vivenciadas/presenciadas pelas mulheres nos serviços de saúde reprodutiva e o reconhecimento da discriminação relacionada à raça/cor e à classe social. Apesar de haver percepção da discriminação racial, as mulheres apresentaram dificuldade em reconhecer que sofriam tais práticas, evidenciando a naturalização das desigualdades raciais no cuidado em saúde reprodutiva.

Racial discrimination can influence the functioning of the health services and the relationships between health professionals and service users, and may be reproduced imperceptibly, through how the people in the vicinity are treated. This study aimed to describe women's perception about racial discrimination in health care practices in reproductive health. It is an exploratory-descriptive study, with a qualitative approach. The information was collected in a Primary Health Care Center in Salvador, Bahia, in 2010, through semi-structured interviews held with 25 women. The technique of thematic analysis was used for analyzing the discourses. The analysis revealed situations of discrimination experienced or witnessed by the women in the reproductive health services and recognition of discrimination related to race/color and to social class. Despite there being perception of racial discrimination, the women had difficulty in recognizing that they suffered such practices, evidencing the naturalization of racial inequalities in reproductive health care.

La discriminación racial puede afectar tanto el funcionamiento de los servicios de salud y las relaciones entre profesionales y usuarios y se puede jugar sin problemas tanto a través del trato a la persona de nuestro entorno ya nosotros mismos. El objetivo del estudio es identificar y describir la percepción de mujeres a cerca de la discriminación de raza en prácticas de cuidado en salud reproductiva. La investigación es del tipo descriptiva, exploratoria, con abordaje cualitativa. Las informaciones fueran colectadas en uma Unidad Basica de Salud em La ciudad de Salvador, Bahia, Brasil, en 2010.

BACKGROUND: There is difficulty in gathering data on the prevalence of human T-cell lymphotropic virus in blood donors as confirmatory testing is not mandatory in Brazil. This suggests there may be an underreporting of the prevalence. OBJECTIVE: To estimate the prevalence of human T-cell lymphotropic virus types 1 and 2 in donors of a blood bank in Caruaru, Brazil. METHODS: This was an observational, epidemiological, descriptive, longitudinal and retrospective study with information about the serology of donors of the Caruaru Blood Center, Fundação de Hematologia e Hemoterapia de Pernambuco (Hemope) from May 2006 to December 2010. The data were analyzed using the Excel 2010 computer program (Microsoft Office(r)). RESULTS: Of 61,881 donors, 60 (0.096%) individuals were identified as potential carriers of human T-cell lymphotropic virus types 1 and 2. Of these, 28 (0.045%) were positive and 32 (0.051%) had inconclusive results in the serological screening. Forty-five (0.072%) were retested; 17 were positive (0.027%) and 3 inconclusive (0.005%). After confirmatory tests, 8 were positive (0.013%). Six (75%) of the confirmed cases were women. CONCLUSION: Epidemiological surveys like this are very important in order to create campaigns to attract donors and reduce the costs of laboratory tests.
