RESUMO

Cardiac hypertrophy (CH) is an adaptive response to maintain cardiac function; however, persistent stress responses lead to contractile dysfunction and heart failure. Although inflammation is involved in these processes, the mechanisms that control cardiac inflammation and hypertrophy still need to be clarified. The NLRP3 inflammasome is a cytosolic multiprotein complex that mediates IL-1ß production. The priming step of NLRP3 is essential for increasing the expression of its components and occurs following NF-κB activation. Hyperthyroidism triggers CH, which can progress to maladaptive CH and even heart failure. We have shown in a previous study that thyroid hormone (TH)-induced CH is linked to the upregulation of S100A8, leading to NF-κB activation. Therefore, we aimed to investigate whether the NLRP3 inflammasome is involved in TH-induced CH and its potential role in CH pathophysiology. Hyperthyroidism was induced in NLRP3 knockout (NLRP3-KO), Caspase-1-KO and Wild Type (WT) male mice of the C57Bl/6J strain, aged 8-12 weeks, by triiodothyronine (7 µg/100 g BW, i.p.) administered daily for 14 days. Morphological and cardiac functional analysis besides molecular assays showed, for the first time, that TH-induced CH is accompanied by reduced NLRP3 expression in the heart and that it occurs independently of the NLRP3 inflammasome and caspase 1-related pathways. However, NLRP3 is important for the maintenance of basal cardiac function since NLRP3-KO mice had impaired diastolic function and reduced heart rate, ejection fraction, and fractional shortening compared with WT mice.

RESUMO

BACKGROUND: Pretreatments of drying can represent an alternative to minimize the negative aspect process on the dry samples. Thus, the influence of ethanol (ET) and freezing (FG) as drying pretreatments was analyzed for slices of papaya. The slices (5 mm) were submitted for drying kinetics (60 °C and 1.5 m s-1 ). Drying kinetics experimental data were fitted using Page's model and a diffusive model with boundary condition of types I and III. Also the thermophysical properties (thermal conductivity and specific heat) were determined and finally, the kinetics of ultrasound-assisted (40 kHz and 132 W) extraction of total phenolic compounds (TPCs) were realized. RESULTS: The combined method (ET + FG) was more efficient in reducing the drying time of papaya slices (48%) and the model 2 simulating the boundary condition of the third type (type III) showed the best fit to the experimental data. Effective diffusivity and convective coefficient were higher for ET + FG, where the maximum reduction in water content was 91% compared to fresh slices. The pretreatments did not influence the thermal conductivity, however, they were significant in the specific heat and in the extraction of TPCs, being higher in the time of 180 min. CONCLUSION: It was confirmed in the results presented that the combined pretreatment ET + FG is the most viable for drying papaya slices. Furthermore, it was found to be the most efficient in minimizing the loss of TPCs. Therefore, this pretreatment has great potential for application in the development of high value-added foods. © 2022 Society of Chemical Industry.

RESUMO

Acute lymphoblastic leukemia (ALL) is the most common childhood cancer worldwide, and it is characterized by the production of immature malignant cells in the bone marrow. Computer vision techniques provide automated analysis that can help specialists diagnose this disease. Microscopy image analysis is the most economical method for the initial screening of patients with ALL, but this task is subjective and time-consuming. In this study, we propose a hybrid model using a genetic algorithm (GA) and a residual convolutional neural network (CNN), ResNet-50V2, to predict ALL using microscopy images available in ALL-IDB dataset. However, accurate prediction requires suitable hyperparameters setup, and tuning these values manually still poses challenges. Hence, this paper uses GA to find the best hyperparameters that lead to the highest accuracy rate in the models. Also, we compare the performance of GA hyperparameter optimization with Random Search and Bayesian optimization methods. The results show that GA optimization improves the accuracy of the classifier, obtaining 98.46% in terms of accuracy. Additionally, our approach sheds new perspectives on identifying leukemia based on computer vision strategies, which could be an alternative for applications in a real-world scenario.

RESUMO

Cardiovascular diseases are among the main causes of mortality in the world. There is evidence of cardiovascular harm after exposure to low lead or mercury concentrations, but the effects of chronic exposure to the association of low doses of these toxic metals are still unknown. This work evaluated after 4 weeks, the association effects of low concentrations of lead and mercury on blood pressure and vascular resistance reactivity. Wistar rats were exposed for 28 days to lead acetate (1st dose of 4 µg/100 g and subsequent doses of 0.05 µg /100 g/day to cover daily losses) and mercury chloride (1st dose of 2.17 µg/kg and subsequent doses of 0.03 µg/kg/ day to cover daily losses) and the control group received saline, i.m. Results showed that treatment increased blood pressure and induced left ventricular hypertrophy. The mesenteric vascular reactivity to phenylephrine and the endothelium-dependent vasodilator response assessed by acetylcholine did not change. Additionally, reduced involvement of vasoconstrictor prostanoids derived from cyclooxygenase was observed in the PbHg group. By other regulatory routes, such as potassium channels, the vessel showed a greater participation of BKCa channels, and a reduction in the participation of Kv channels and SKCa channels. The endothelium-independent smooth muscle relaxation was significantly impaired by reducing cGMP, possibly through the hyperstimulation of Phosphodiesterase-5 (PDE5). Our results suggested that exposure to low doses of lead and mercury triggers this compensatory mechanism, in response to the augment of arterial pressure.

RESUMO

A multidrug-resistant CTX-M-15-producing Klebsiella pneumoniae (KpP1 strain) was isolated from a native Amazonian fish (Brachyplatystoma filamentosum) at the Brazilian Amazon. The strain was identified by MALDI-TOF. The genome was extracted, purified and a Nextera DNA Flex library was prepared and sequenced by Illumina platform. The sequenced genome was de novo assembled using Unicycler and in silico prediction accomplished by curated bioinformatics tools. The size of the genome is 5.6 Mb with 5715 genes. Whole-genome sequencing analysis revealed the presence of wide resistome, with genes conferring resistance to clinically relevant antibiotics, heavy metals and disinfectants. The KpP1 strain was assigned to the sequence type ST3827, KL111 (wzi113) and O3b locus. Native freshwater fish sold in wet markets of the Amazonian region could be an important vehicle for transmission of multidrug-resistant bacteria to humans. This study may give genomic insights on the spread of critical-priority WHO pathogens in a One Health context.

RESUMO

BACKGROUND: The Coronavirus disease (COVID-19) is highly infectious, with the recent World Health Organization decree confirming a global public health emergency. The outcomes related to maternal and fetal health among pregnant women infected with the virus are still poorly understood. The world population has been waiting for answers and remains constantly alert about the pandemic's progress. It is not yet known what impact this pandemic experience will have on the population's mental health, especially pregnant women. METHOD: We aim to understand and discuss the experiences of women who were infected by COVID-19 during pregnancy, in relation to the illness process, community relations, and social media influences. This is a qualitative study in which we will interview women who were infected by COVID-19 during pregnancy and received medical care from a tertiary university hospital specializing in women's health in Brazil. We will use the techniques of Semi-Directed Interviews of Open and In-depth Questions, socio-demographic and health data sheets, and Field Diaries. We will use purposive sampling and the criterion of theoretical saturation for its construction. The interviews will be conducted by phone or video call, with audio recorded for later transcription. The treatment of the data will be completed through Thematic Analysis and discussed in light of the Health Psychology framework, with the production of categories that answer the proposed research questions. DISCUSSION: It is expected that the results contribute to the understanding about the demands that come to the health professional of women infected by COVID-19 during pregnancy in a pandemic situation. INTRODUçãO: A doença causada pelo coronavírus (COVID-19) é altamente infecciosa, com a recente declaração da Organização Mundial de Saúde confirmando emergência global de saúde pública. Os desfechos relacionados a saúde materno-fetal entre gestantes infectadas pelo vírus ainda são pouco conhecidos. A população mundial tem aguardado respostas e se mantém constantemente em alerta sobre o progresso da pandemia. Ainda não se sabe qual será o impacto da experiência da pandemia sobre a saúde mental da população, especialmente entre mulheres grávidas. MéTODO: O objetivo deste estudo é compreender e discutir as experiências de mulheres infectadas pelo COVID-19 durante a gravidez, em relação ao processo de adoecimento, às relações comunitárias e a influência de mídias sociais. Este é um estudo qualitativo em que serão entrevistadas mulheres infectadas pelo COVID-19 durante a gestação, atendidas em um hospital universitário terciário especializado em saúde da mulher no Brasil. Serão usadas as técnicas de Entrevistas Semi-Dirigidas de Perguntas Abertas em Profundidade, ficha de dados sociodemográficos e de saúde e diários de campo. A amostra será selecionada intencionalmente, usando o critério de saturação teórica para a sua construção. As entrevistas serão conduzidas por telefone ou videoconferência, com áudio gravado para posterior transcrição. O tratamento dos dados seguirá a Análise Temática e os resultados serão discutidos sob conceitos de Psicologia da Saúde, com a produção de categorias que respondam as questões de pesquisa propostas. DISCUSSãO: Espera-se que os resultados contribuam para a compreensão de demandas emergentes entre profissionais de saúde para mulheres infectadas pelo COVID-19 durante a gestação em situação de pandemia.

RESUMO

OBJECTIVE To analyze the the social representations of young Catholics about HIV/AIDS prevention and sexuality. METHOD Mixed study, based on the theory of social representations, held in 2015 with 84 young Catholics participating in the group "World Youth Day" on Facebook. The data were collected through the technique of free association of words and in-depth interview. For the information analysis, the software Tri-Deux-Mots and Alceste were used. RESULTS Sexuality is processed in the representational field of young people as being associated with the sexual practice. In turn, the prevention of HIV, a phenomenon represented as intrinsic to sexuality, occurs through the use of condoms or fidelity within marriage. CONCLUSION Young Catholics represent the prevention of HIV/AIDS as a transverse phenomenon to sexuality, whose sexual practices are anchored both in hegemonic and progressive discourses.

RESUMO

Black rice (Oryza sativa) stands out for its high content of bioactive compounds with functional properties that play an important role in health benefits. The phytochemical level is affected by industrial processing due to its instability to the hydrothermal process. Studies about the influence of industrial processing on the phytochemical profile of black-rice-based foods are still scarce. This study carried out a comprehensive review of the influence of industrial applications on the bioactive compounds in food products based on black rice and their health-promoting effects. Most industrial processes such as drying, storage, cooking, and extrusion affect phytochemical content and antioxidant capacity. Alternatively, technologies such as fermentation, UV-C irradiation, and sprouting can maintain or improve the phytochemical content in black rice products.

RESUMO

INTRODUCTION: Sudden infant death syndrome (SIDS) is the unexpected death of an infant less than 1 year old, which occurs without presentation of any signs of mortality risk and it is not explained even after investigation, necropsy and review of the site of death. The nurse is an essential healthcare professional working with children and families who can contribute to preventing avoidable deaths of infants. Because SIDS is preventable, permanent education of the healthcare team, family members and infant caregivers is necessary. OBJECTIVE: To explore the scientific literature about knowledge, attitudes and practice on SIDS. METHODS AND ANALYSIS: A scoping review will be conducted. Quantitative or qualitative primary studies, theses, dissertations and technical and governmental documents in English, Spanish, French or Portuguese will be considered, without a time limit for selection with search, in the databases: Pubmed, Embase, Scopus, Virtual Health Library, Digital Library of Theses and Dissertations of the Brazilian Institute and Cochrane. A search strategy will be elaborated with the keywords in the following themes: knowledge, attitudes, practice, sudden infant death and healthcare. The eligibility criteria will be applied to references of selected articles to identify new studies. The studies selected will be subjected to thematic content analysis, which allows data interpretation through a systematic classification process for coding themes to the analysis of quantitative and qualitative studies and meta-aggregation. NVIVO V.14 software will be used to organise, code and validate the data. ETHICS AND DISSEMINATION: Ethics approval is not required. The results will be disseminated to the health science community through professional networks, conference presentations and publication in a scientific journal.

RESUMO

The overuse of antimicrobials in livestock has contributed to the emergence and selection of clinically relevant multidrug-resistant bacteria. In Brazil, there is no conclusive information on the occurrence of Escherichia coli producing extended-spectrum ß-lactamase (ESßL) in cattle breeding, which is an important sector of agribusiness in this country. Herein, we investigated the presence of ESßL-positive E. coli strains in dairy cattle from a commercial farm with routine practice of therapeutic cephalosporins. Ninety-five rectal swab samples were collected from healthy dairy calves and cows under treatment with ceftiofur. Samples were screened for the presence of ESßL producers, and positive isolates were identified by MALDI-TOF, with subsequent screening for genes encoding ESßL variants by PCR and sequencing. The presence of ESßL (CTX-M-15)-producing E. coli was confirmed in calves, and lactating and dry cows. Most ESßL strains with genetic homologies ≥ 90% were grouped into two major PFGE clusters, confirming the suscessful expansion of clonally related lineages in animals from different lactating cycles, on the same property. Four representatives CTX-M-15-positive E. coli strains had their genomes sequenced, belonging to the clonal complex (CC) 23 and sequence type (ST) 90. A phylogeographical landscape of ST90 was performed revealing a global One Health linkage. Our results highlight the intestinal microbiota of dairy cattle as a hotspot for the spread of critical priority ESßL-producing E. coli and demonstrate that ST90 is an international clone genomically adapted to human and animal hosts, which deserve additional investigation to determine its zoonotic potential and impact in food chain.

RESUMO

INTRODUCTION: There are particularities of chronic kidney disease (CKD) in women and their treatment. The biology of women exposes them to greater risk factors for CKD and both pregnancy and the postpartum period place an additional burden on renal health. Pregnancy complications may cause or worsen CKD. OBJECTIVE: To explore the experiences of women with CKD undergoing hemodialysis in relation to their reproductive history. METHODS: This study consisted of clinical-qualitative design with semi-structured individual interviews and open-ended questions. The sample selection was intentional and according to the theoretical saturation criterion. The data analysis was carried out based on the seven steps of the clinical-qualitative content analysis and validated by Nvivo11. This study was conducted in a public hemodialysis clinic of the Brazilian National Health System. RESULTS: Twelve women undergoing hemodialysis were interviewed. The results from the analysis revealed three categories: 1) Association of pregnancy with CKD; 2) Nebulosity in relation to diagnosis and reproductive history 3) Being a woman undergoing hemodialysis. CONCLUSION: Our study showed the importance of considering the specificities of CKD in women, suggesting that these issues are important for diagnosis and treatment adherence. Consideration of reproductive life history allows the health of women undergoing hemodialysis to be promoted holistically, including aspects of mental health.

RESUMO

BACKGROUND: Varicocele is one of the main causes of male infertility. Although the pathophysiology mechanism of varicocele is very well described and understood, there are some unanswered questions that remains unknown. Some studies have previously described the state of testicular inflammation and sperm in animal models, especially the mouse model, and the seminal plasma of men with varicocele, with or without changes in semen parameters. METHODS OF STUDY: This review intended to verify the role of inflammatory mechanism in varicocele, using clinical studies as well as animal model studies on the effect of inflammation caused by varicocele on the function of testicular somatic and germ cells. RESULTS: In-vivo studies confirmed whether anti-inflammatory molecules could treat the semen of men with varicocele and rats with varicocele. The use of different anti-inflammatory agents in mouse model studies provided a new perspective for future clinical studies to investigate the effect of concurrent treatment with surgery to improve surgical outcomes. CONCLUSION: Similar to animal model studies, previously conducted clinical trials have demonstrated the effectiveness of anti-inflammatory therapy in varicocele patients. However, clinical trials using anti-inflammatory are needed to be conducted agents to evaluate different aspects of this therapeutical approach in varicocele patients.

RESUMO

Extended spectrum ß-lactamase (ESBL)-producing Enterobacterales has spread rapidly around the world, reaching remote areas. In this regard, wild birds that acquire ESBL producers from anthropogenically impacted areas can become reservoirs, contributing to further dissemination of antimicrobial-resistant bacteria categorized as critical priority pathogens to remote environments, during migration seasons. We have conducted a microbiological and genomic investigation on the occurrence and features of ESBL-producing Enterobacterales in wild birds from the remote Acuy Island, in the Gulf of Corcovado, at Chilean Patagonia. Strikingly, five ESBL-producing Escherichia coli were isolated from migratory and resident gulls. Whole-genome sequencing (WGS) analysis revealed the presence of two E. coli clones belonging to international sequence types (STs) ST295 and ST388, producing CTX-M-55 and CTX-M-1 ESBLs, respectively. Moreover, E. coli carried a wide resistome and virulome associated with human and animal infections. Phylogenomic analysis of global and publicly genomes of E. coli ST388 (n = 51) and ST295 (n = 85) clustered gulls isolates along to E. coli strains isolated from the environment, companion animal and livestock in the United States of America, within or close to the migratory route of Franklin's gull, suggesting a possible trans hemispheric movement of international clones of WHO critical priority ESBL producing pathogens.

RESUMO

A simplex-centroid design was used to evaluate the effect of proportions (0 to 100%) of whole wheat flour (WWF), whole mung bean flour (WMF) and whole rice flour (BRF) on the quality of cookies savory. The dough cut in the shape of a disks (37 mm × 2 mm) showed a 13% retraction in diameter when they contained exclusively WWF, it was less intense (5%) with BRF and null (0%) with WMF. The dough expansion occurred only vertically, the thicknesses of the WWF, WMF and BRF biscuits were 5.33, 2.79 and 2.13 times greater than the initial dough height, respectively. This characteristic showed high correlations with volumetric expansion (r = 0.95), specific volume (r = 0.90), hardness (r = 0.92), fracturability (r = 0.93) and spread factor (r = -0.96). BRF increased the value of the color difference of the biscuits up to 17.70, the effect of WMF was smaller (6.51). Only the radial expansion index correlated with the trough (r = 0.76), final viscosity (r = 0.79) and setback (r = 0.77) parameters. Considering the main desirable physical characteristics in savory biscuits, the highest global desirability obtained was for the proportion of 49% WWF, 24% WMF and 27% BRF.

RESUMO

OBJECTIVE: The objective of this study was to assess the risk and prevalence of oral cancer in patients with systemic lupus erythematosus (SLE) or discoid lupus erythematosus (DLE). STUDY DESIGN: The review included observational cohort and cross-sectional studies that investigated the incidence or prevalence of oral cancer in adults with confirmed diagnoses of SLE or DLE. Studies were selected based on predefined eligibility criteria, including the use of specific diagnostic criteria for SLE and DLE. After searches in PubMed/MEDLINE, EMBASE, Scopus, Web of Science, LILACS, and LIVIVO databases and gray literature for relevant studies, the selection process was conducted by independent reviewers. RESULTS: A total of 5,545 articles were identified. After screening, 8 studies met the inclusion criteria. The pooled risk estimate indicated a significantly increased risk of oral cancer in patients with SLE (risk ratio = 2.69; 95% confidence interval, 1.75 to 4.16; I2 = 0%; P = .78) compared with the general population. The pooled prevalence of oral cancer in patients with DLE was 10% (95% ci, 0.03 to 0.13; I2 = 59%; P = .12). CONCLUSIONS: This review provides evidence supporting an elevated risk for individuals with SLE or DLE developing oral cancer. The findings highlight the importance of monitoring oral mucosa in patients with these conditions.

RESUMO

Cystathionine ß-synthase (CBS), CSE (cystathionine γ-lyase) and 3-mercaptopyruvate sulfurtransferase (3-MST) have emerged as three significant sources of hydrogen sulfide (H2S) in various forms of mammalian cancer. Here, we investigated the functional role of CBS' and 3-MST's catalytic activity in the murine breast cancer cell line EO771. The CBS/CSE inhibitor aminooxyacetic acid (AOAA) and the 3-MST inhibitor 2-[(4-hydroxy-6-methylpyrimidin-2-yl)sulfanyl]-1-(naphthalen-1-yl)ethan-1-one (HMPSNE) were used to assess the role of endogenous H2S in the modulation of breast cancer cell proliferation, migration, bioenergetics and viability in vitro. Methods included measurements of cell viability (MTT and LDH assays), cell proliferation and in vitro wound healing (IncuCyte) and cellular bioenergetics (Seahorse extracellular flux analysis). CBS and 3-MST, as well as expression were detected by Western blotting; H2S production was measured by the fluorescent dye AzMC. The results show that EO771 cells express CBS, CSE and 3-MST protein, as well as several enzymes involved in H2S degradation (SQR, TST, and ETHE1). Pharmacological inhibition of CBS or 3-MST inhibited H2S production, suppressed cellular bioenergetics and attenuated cell proliferation. Cell migration was only inhibited by the 3-MST inhibitor, but not the CBS/CSE inhibitor. Inhibition of CBS/CSE of 3-MST did not significantly affect basal cell viability; inhibition of 3-MST (but not of CBS/CSE) slightly enhanced the cytotoxic effects of oxidative stress (hydrogen peroxide challenge). From these findings, we conclude that endogenous H2S, generated by 3-MST and to a lower degree by CBS/CSE, significantly contributes to the maintenance of bioenergetics, proliferation and migration in murine breast cancer cells and may also exert a minor role as a cytoprotectant.

RESUMO

This article discusses the social representations of women living in common-law marriage in terms of their vulnerability to becoming infected with HIV/AIDS. Data were obtained through the free association of words, and consisted of an excerpt of a study founded on the Social Representations Theory developed with HIV-negative women living in the state capital and cities in the interior of Bahia. The correspondence factor analysis showed significance for the variables: origin, education level and time spent in common-law marriage. Their acceptance of marital affairs emerged as a vulnerability factor for respondents with one to five years spent in common-law marriage, living in cities in the interior. Women from the capital, with 6-10 years spent in common-law marriage, reported monogamy as a form of prevention. Women with a longer common-law marriage who had completed only a primary education reported feeling invulnerable, which was the opposite of those with one to five years in common-law marriage with a secondary education. Results show there is a need for more interventions aiming to denaturalize the socio-cultural coercions that generate representations and make women in common-law marriages more vulnerable to AIDS.

OBJECTIVE: To assess the quality of life (QoL) of pregnant women with systemic lupus erythematosus (SLE) treated at a high-risk prenatal outpatient clinic during the third trimester of gestation. METHODS: An observational descriptive study was performed in a high-risk prenatal outpatient clinic. Women in the third trimester of pregnancy and undergoing antenatal care between July 2017 and July 2019 answered the abbreviated World Health Organization Quality of Life (WHOQOL-BREF) questionnaire, consisting of 26 questions divided into 4 domains (physical, psychological, social and environmental). RESULTS: We interviewed 50 pregnant women with a mean gestational age of 30 weeks (standard deviation [SD]: 10 weeks) who were diagnosed with SLE. The average age of the participants was 30 years (SD: 14.85), and the average time since the diagnosis of SLE was of 9.06 years (SD: 6.8 years). Most participants had a partner, did not plan their pregnancy (76%), and did not use contraception prior to pregnancy (80%). The score of each domain ranges from 0 (the worst score) to 100 (the best score). The means ± SDs of the scores of the participants on each domain were: physical - 52.21 ± 18.44); psychological - 64.17 ± 18.56); social - 66.33 ± 27.09); and environmental - 64.56 (18.53). The means ± SDs of the general QoL, and health-related QoL items were of 70.50 ± 24.06 and 70.00 ± 30.72 respectively. CONCLUSION: The physical domain presented the lowest scores compared with the other three domains. Pregnant women with SLE had high overall QoL scores, and their health-related QoL scores were also relatively high.


OBJETIVO: Investigar a qualidade de vida (QV) de gestantes com lúpus eritematoso sistêmico (LES), em acompanhamento ambulatorial pré-natal de alto risco, durante o terceiro trimestre de gestação. MéTODOS: Foi realizado um estudo observacional descritivo em ambulatório de pré-natal de alto risco. As mulheres em acompanhamento pré-natal no terceiro trimestre de gravidez entre julho de 2017 e julho de 2019 responderam ao questionário abreviado de Qualidade de Vida da Organização Mundial de Saúde (abbreviated World Health Organization Quality of Life, WHOQOL-BREF, em inglês), composto por 26 questões divididas em 4 domínios (físico, psicológico, social e ambiental). RESULTADOS: Foram entrevistadas 50 gestantes com diagnóstico de LES e média de 30 semanas de idade gestacional (desvio padrão [DP]: 10 semanas). A idade média das participantes foi de 30 anos (DP: 14,85), e o tempo médio desde o diagnóstico de lúpus foi de 9,06 anos (DP = 15,55 anos). A maioria das participantes tinha companheiro, não havia planejado a gravidez (76%), e não fazia uso de anticoncepcional antes da gravidez (80%). A pontuação em cada domínios varia de 0 (pior pontuação) a 100 (melhor pontuação). As médias ± DPs das pontuações das participantes em cada domínios foram: físico ­ 52,21 ± 18,44; psicológico ­ 64,17 ± 18,56; social ­ 66,33 ± 27,09; e ambiental ­64,56 ± 18,53). As médias ± DPs dos itens relativos à QV geral e à QV relacionada à saude foram de 70,50 ± 24,06) e 70,00 ± 30,72, respectivamente. CONCLUSãO: O domínio físico apresentou as menores pontuações em comparação com os outros três domínios. Mulheres grávidas com LES tiveram pontuação alta no item de QV geral, e a pontuação no item de QV relacionada à saúde também foi relativamente alta.
