Clear Aligners and Miniscrews in a Scissor Bite Adult Treatment.

Scissor bite does not correct spontaneously. It gradually worsens by overeruption, negatively affecting masticatory function. It is intended with this manuscript to evaluate the different treatment strategies to correct this malocclusion in adult patients, exploring treatment with clear aligners, bite ramps, and MS (miniscrews), especially in this case of a patient with unilateral right scissor bite, with high dental compensation in the three planes of space, asymmetrical sagittal dental position, overeruption on the scissor bite condition, and a high mandibular arch constriction and maxillary expansion. A comprehensive literature research was performed from 2002 until March 2023. PubMed and BVS databases were used, with the following keywords: "scissor bite OR brodie bite" AND "malocclusion" AND "treatment OR correction OR therapeutics". Since correcting skeletal asymmetries after the growth completion is challenging, adult patient cases often involve a combined orthodontic-surgical approach. In the present clinical case, the severe limitations to decompensating tooth positions for a surgical treatment, with the necessity to perform lower asymmetric extraction and a must longer orthodontic treatment, were the major reasons to avoid the surgical approach, after the scissor bite correction. In spite of this, the efficiency of the clear aligners and auxiliaries like bite ramps, MS, and elastics in successfully correcting a complex scissor bite in an adult patient was demonstrated, with significant esthetic and functional commitment, demonstrated by the case reliability PAR (peer assessment rating) index.

Case Study: Rosai-Dorfman Disease and Its Multifaceted Aspects.

Rosai-Dorfman Disease (RDD) is a rare non-Langerhans histiocytosis, usually self-limited and presenting with massive, painless, bilateral cervical lymphadenopathy, with or without constitutional symptoms. Extranodal disease is frequently present, and may happen in the absence of lymph node involvement, symptomatology and differential diagnosis will depend on the site affected and fatal cases may occur. The authors present two cases of Rosai-Dorfman disease (RDD), diagnosed through immunohistochemistry, with different progressions, one with complete remission and one culminating in death, highlighting the variety of presentations and the diagnostic difficulty. RDD is a rare condition with clinical presentations similar to several diseases, and should be considered in the differential diagnosis of lymphadenopathy with extranodal lesions.

Quality of life of women who underwent breast cancer treatment relative to sociodemographic, behavioral, and clinical factors.

OBJECTIVE: Patients with cancer often undergo multiple extended treatments that decrease their quality of life. However, the quality of life of women with breast cancer after they undergo treatment remains underexplored in Brazil. Therefore, this study determined sociodemographic, behavioral, and clinical factors related to the post-treatment quality of life of women with breast cancer. METHODS: This cross-sectional study involved 101 women diagnosed with breast cancer between 2014 and 2016 and treated at a Brazilian Oncology Reference Service. Data were collected from them using face-to-face surveys. Quality of life was evaluated using the European Organization for the Research and Treatment of Cancer Core Quality of Life questionnaire (EORTC QLQ-C30) and EORTC Breast Cancer-specific Quality of Life questionnaire (EORTC QLQ-BR23). The data collected were analyzed using Student's t-test and Mann-Whitney U test. RESULTS: The median score on the global health, functional, and symptom scales of the EORTC QLQ-C30 was 75.00 (Interquartile range=33.33), 75.99 (Standard deviation [SD]=19.26), and 19.67 (SD=16.91), respectively. The mean score on the functional and symptom scales of the EORTC QLQ-BR23 was 61.89 (SD=17.21) and 20.12 (SD=16.94), respectively. Furthermore, higher post-treatment quality of life was found to be associated with being aged 50 or more, being Black, having eight or more years of education, having a partner, having a paying job, receiving treatment from the private healthcare system, having a higher income, living in the municipality where healthcare services are availed, engaging in physical activity, not smoking, being more religious, having more social support, not being overweight, having no comorbidities, and undergoing lumpectomy. CONCLUSION: Sociodemographic, behavioral, and clinical factors significantly impact the quality of life of women who undergo breast cancer treatment. Implementing interventions that improve health and reducing inequalities in the access to healthcare services can improve the quality of life of these patients. BACKGROUND: Sociodemographic, clinical, and lifestyle factors impact the quality of life of breast cancer survivors. BACKGROUND: Breast cancer therapy may affect future perspectives and emotional, cognitive, and sexual function. BACKGROUND: Some aspects of quality of life still require attention from health professionals. BACKGROUND: Higher post-treatment quality of life of women with breast cancer is linked to being aged 50 or more, being Black, having 8 or more years of education, having a partner, having a paying job, receiving care from private healthcare, having a high per capita income, residing in the municipality where the service is availed, engaging in physical activity, not smoking, greater religiosity, having more social support, having a normal weight, having no comorbidities, and undergoing lumpectomy.

Scissor Bite in Growing Patients: Case Report Treated with Clear Aligners.

Scissor bite (SB.) is a rare malocclusion that is challenging to diagnose and is often associated with a retrognathic mandible and a series of functional and structural abnormalities that negatively affect the patient. This article intends to analyze the treatment approaches applied to growing patients younger than 16 years old, comparing the conventional appliances described in the literature and a clinical case treated with clear aligners with mandibular advancement (MA.). SB is primarily related to skeletal Class I and II, according to Angle classification. In the various cases analyzed, it can also be mentioned as a significant number of cases with SB of dental origin (seven of dental and four of skeletal) in young patients. In children and adolescents who still have growth potential, the therapeutic possibilities are numerous. A comprehensive literature search was manually performed from 2002 until January 2023, in PubMed and BVS databases with the following conjugated keywords: "scissor bite OR brodie bite" AND "malocclusion" AND "treatment OR correction OR therapeutics". The present case report on a young patient demonstrated the efficiency of the clear aligners with MA to correct an SB, associated with several functional and structural anomalies such as Class II division 1 with an increased overjet and overbite as well as a severe curve of Spee in a hypodivergent biotype.

Occlusal Changes with Clear Aligners and the Case Complexity Influence: A Longitudinal Cohort Clinical Study.

BACKGROUND: Clear aligners (CA) are used 22 h daily, creating a bite-block effect. This work aims to (i) analyze occlusal changes before the beginning of treatment, after the first set of CA and after the use of additional aligners; (ii) compare planned occlusal contacts with the ones obtained after the first set of CA; (iii) analyze the occlusal changes occurred after reaching the orthodontic goals after 3 months of using CA only at night; (iv) evaluate and characterize which tooth movements did not allow the treatment to be completed at the end of the first set of aligners, and finally (v) verify the possible relation between the changes in occlusal contact and areas and parameters such as case complexity and facial biotype. MATERIALS AND METHODS: A quantitative, comparative, and observational longitudinal cohort study design was implemented to evaluate the clinical data and the complexity levels of cases receiving CA. A non-probabilistic and convenience sample of 82 individuals was recruited. The orthodontic malocclusion traits were classified as simple, moderate, or complex corrections based on the basis of the Align® recommendations with the Invisalign® evaluation tool. According to the Invisalign® criteria, patients need only one complex problem for their case to be classified as complex. Meshlab® v. 2022.02, ClinCheck® version Pro 6.0, My-Itero® version 2.7.9.601 5d plus, and IBM® SPSS Statistics software (Statistical Program for Social Sciences), version 27.0 for Windows were the software® used. RESULTS: A statistically significant decrease in area and occlusal contacts number were observed from before the start of orthodontic treatment (T0) to the end of treatment (T1). The changes in the occlusal area (from T0 to T1) were statistically different between hyperdivergent (28.24 [15.51-40.91]) and hypodivergent (16.23 [8.11-24.97]) biotypes (p = 0.031). A significant difference between the hyperdivergent (4.0 [2.0-5.0]) and normodivergent (5.5 [4.0-8.0]) group was found in T1 for the anterior contacts (p = 0.044). Anterior contacts obtained were significantly higher than the planned (p = 0.037) Between T1 and T2 statistically significant increases of occlusal areas, posterior and total contacts were observed. CONCLUSIONS: Occlusal contact and area were decreased, either at the end of the first set or after the use of additional aligners. Anterior occlusal contacts obtained were higher than planned as opposed to posterior occlusal contacts obtained. The hardest tooth movements to achieve to complete the treatment were distalization, rotation, and posterior extrusion. After completing orthodontic treatment (T1) to 3 months after (T2) using additional aligners only at night, posterior occlusal contacts were significantly increased, which could be due to the natural settling of the teeth in this period.

Breast cancer survival and the health system in Brazil: an analysis of public and private healthcare.

Background: The incidence of breast cancer is increasing globally; however, survival outcomes vary and are lower in developing countries. Methods: We analyzed the 5- and 10-year survival rates for breast cancer according to the type of healthcare insurance (public vs. private) in a referral center for cancer care in the Brazilian southeast region. This hospital-based cohort study included 517 women diagnosed with invasive breast cancer between 2003 and 2005. The Kaplan-Meier method was used to estimate the probability of survival, and the Cox proportional hazards regression model was used to assess prognostic factors. Results: The 5- and 10-year breast cancer survival rates were as follows: private healthcare service survival rate of 80.6% (95% CI 75.0-85.0) and 71.5% (95% CI 65.4-77.1), respectively, and public healthcare service survival rate of 68.5% (95% CI 62.5-73.8) and 58.5% (95% CI 52.1-64.4), respectively. The main factors associated with the worst prognosis were lymph node involvement in both healthcare services and tumor size >2 cm only in public health services. The use of hormone therapy (private) and radiotherapy (public) was associated with the best survival rates. Conclusions: The survival discrepancies found between health services can be explained mainly by the difference in the stage of the disease at the time of diagnosis, indicating inequalities in access to the early detection of breast cancer.

OBJECTIVES: to construct and validate an educational video storyboard about care for premature newborns at home. METHODS: a methodological study, with the construction of an educational video storyboard, validated with 14 judges. Content was selected from scoping review. For data collection, a validated instrument was used. The criterion for validity was agreement greater than 80%, analyzed using the Content Validity Index. RESULTS: the storyboard construction was guided by the Cognitive Theory of Multimedia Learning theoretical framework. Construction and validity took place from May to December 2020. The storyboard's final version lasted 10 minutes, and was validated in terms of objective, structure, presentation and relevance, with a Content Validity Index of 0.9. CONCLUSIONS: the storyboard of the educational video proved to be valid and adequate for health promotion in developing care for premature newborns at home.

Interceptive Treatment with Invisalign® First in Moderate and Severe Cases: A Case Series.

The increasing demand for more aesthetic/comfortable orthodontic alternatives fostered the utilization of clear aligners in recent years. However, the efficacy of clear aligners for treating complex malocclusions is often treated with scepticism. This case series aims to evaluate the predictability of the Invisalign® First system in moderate and severe cases requiring interceptive orthodontic treatments in mixed dentition. A total of 23 patients with 102 interceptive orthodontic malocclusion traits were selected for orthodontic treatment with Invisalign® First and were examined over 18 months (Phase 1). Clinical assessments included ClinCheck® predictions, cephalometric measurements, and measuring tools commonly used to quantify tooth movement. Measurements taken at the beginning and end of the treatment were compared. The complexity degree of each case was established based on the set of problems presented by each patient. All treatment objectives were achieved within 18 months, except for two Class II cases, with 69% of them solved with the first set of aligners. Additional aligners were used in the remaining cases. Even though these 23 cases suggest that the Invisalign® First (Phase 1) may be effective in most interceptive problems, controlled randomized clinical trials are required to evaluate movement predictability and how this relates to the problem complexity and additional aligners required.

Human Interleukin-1ß Profile and Self-Reported Pain Monitoring Using Clear Aligners with or without Acceleration Techniques: A Case Report and Investigational Study.

Introduction: There is a growing demand for more aesthetic, comfortable, and faster orthodontic treatments, and clear aligners emerged as a solution to fulfill this need. However, the effectiveness of clear aligners to treat complex malocclusions is yet contentious. The use of acceleration methods could improve the efficacy of clear aligners by stimulating cells' mechanobiology through numerous pathways, but this hypothesis is still poorly explored. Objective: We aimed to monitor the release profile of an inflammatory marker-the interleukin-1ß-and to evaluate its relationship with self-reported pain scores with and without the use of acceleration techniques during an orthodontic treatment requiring difficult tooth movements with clear aligners. Case Report. Here, we report a case of a 46-year-old female patient who presented functional and aesthetic complaints. Intraoral examination revealed a diminished overjet and overbite, rotation of teeth 45 and 24, absence of teeth 25, 35, and 36, buccolingual dislocation of tooth 21, a tendency to a Class III malocclusion, and a 2 mm left deviation of the lower midline. This study is divided into three stimulation phases: no stimulation, mechanical vibration stimulation, and photobiomodulation. Interleukin-1ß levels in gingival crevicular fluid samples from the pressure side of six selected teeth were evaluated at four time points after the orthodontic treatment onset. Pain monitoring in those teeth was performed using a visual analogue scale at the same time points. Results: Interleukin-1ß protein production peaked 24 h after treatment onset. Complex movements were associated with increased self-reported pain. Conclusion: Clear aligners show limitations in solving complex tooth movements, even when combined with acceleration. The development of customized and programmable stimulation microdevices integrated into "smart aligners," which could be designed to specifically stimulate the direction of movement and stimulation parameters and could constitute a solution to optimize the orthodontic tooth movement with clear aligners.

Time to diagnosis and treatment for breast cancer in public and private health services.

OBJECTIVE: To analyze the time to diagnosis and treatment for breast cancer and the associated factors, according to the type of care (public vs. private). METHODOLOGY: Retrospective cohort study with 477 women diagnosed with breast cancer between 2014 and 2016. Data were collected in an oncology service in a municipality in Minas Gerais, in the 2018-2019 period. Analyzes were performed using the Kaplan-Meier method and Cox's proportional regression model. RESULTS: The median time to diagnosis was 70 days, being shorter for women who discovered the disease through screening tests and who were diagnosed in early stages of the disease. The median time for treatment was 32 days, which was shorter for women assisted by private health service, with a high level of education and who were diagnosed in early stages. CONCLUSIONS: Private care and facilitators of access to breast cancer care were associated with shorter waiting times.

Histological and Immunohistochemical Characteristics for Hereditary Breast Cancer Risk in a Cohort of Brazilian Women.

OBJECTIVE: The study aimed to characterize the clinical, histological, and immunohistochemical profile of women with invasive breast cancer, according to the risk for Hereditary Predisposition Breast and Ovarian Cancer Syndrome in a Brazilian population. METHODS: This is a retrospective study performed from a hospital-based cohort of 522 women, diagnosed with breast cancer treated at an oncology referral center in the Southeast region of Brazil, between 2014 and 2016. RESULTS: Among the 430 women diagnosed with invasive breast cancer who composed the study population, 127 (29.5%) were classified as at increased risk for hereditary predisposition to breast and ovarian cancer syndrome. There was a lower level of education in patients at increased risk (34.6%) when compared with those at usual risk (46.0%). Regarding tumor characteristics, women at increased risk had higher percentages of the disease diagnosed at an advanced stage (32.3%), and with tumors > 2cm (63.0%), with increased prevalence for both characteristics, when compared with those at usual risk. Furthermore, we found higher percentages of HG3 (43.3%) and Ki-67 ≥ 25% (64.6%) in women at increased risk, with prevalence being about twice as high in this group. The presence of triple-negative tumors was observed as 25.2% in women at increased risk and 6.0% in women at usual risk, with the prevalence of absence of biomarkers being 2.5 times higher among women in the increased risk group. CONCLUSION: From the clinical criteria routinely used in the diagnosis of breast cancer, the care practice of genetic counseling for patients at increased risk of hereditary breast cancer in contexts such as Brazil is still scarce.

OBJETIVO: O presente estudo buscou caracterizar o perfil clínico, histológico e imunohistoquímico de mulheres com câncer de mama invasivo segundo o risco para a Síndrome de Predisposição Hereditária ao Câncer de Mama e Ovário em uma população brasileira. MéTODOS: Trata-se de um estudo retrospectivo realizado a partir de uma coorte hospitalar composta por 522 mulheres diagnosticadas com câncer de mama entre 2014 e 2016 assistidas em um centro de referência oncológica localizado na região sudeste brasileira. RESULTADOS: Entre as 430 mulheres diagnosticadas com câncer de mama invasivo que compuseram a população de estudo, 127 (29,5%) foram classificadas como de risco aumentado para a síndrome de predisposição hereditária ao câncer de mama e ovário. Verificou-se menor nível de escolaridade nas pacientes com risco aumentado (34,6%) quando comparadas àquelas consideradas como de risco habitual (46,0%). Quanto às características do tumor, as mulheres de risco aumentado apresentaram maiores percentuais de doença diagnosticada em estádio avançado (32,3%) e com tumores > 2cm (63,0%), com prevalência aumentada para ambas as características, quando comparadas àquelas de risco habitual. Ainda nas mulheres de risco aumentado, foram encontrados maiores percentuais de GH3 (43,3%) e Ki-67 ≥ 25% (64,6%), com prevalência cerca de duas vezes maior neste grupo. A presença de tumores triplo-negativos foi observada em 25,2% nas mulheres de risco aumentado e 6,0% nas mulheres de risco habitual, com prevalência de ausência de biomarcadores 2,5 vezes maior entre as mulheres do grupo de risco aumentado. CONCLUSãO: A partir dos critérios clínicos rotineiramente utilizados no diagnóstico do câncer de mama, a prática assistencial do aconselhamento genético para as pacientes com risco aumentado de câncer de mama hereditário em contextos como o do Brasil ainda é escarça.

Macrobrachium/ Spence Bate, 1868 (Decapoda: Palaemonidae): New records, range extension and geographic distribution in the Northeastern Caatinga amp; Coastal Drainages, and São Francisco hydrographic ecoregions, Northeast of Brazil.

This study constitutes the most comprehensive effort ever done to assess the faunal diversity of the Macrobrachium genus within two ecoregions that encompass part of the northeastern Brazil: the Northeastern Caatinga Coastal Drainages, and the São Francisco (Lower-middle and Lower portions). Through sampling in several of their hydrographic basins, bibliographic research, and consulting scientific collections, our results reveal the occurrence of five species along these ecoregions: Macrobrachium acanthurus, M. amazonicum, M. carcinus, M. jelskii and M. olfersii. We also provide the first record of these species for several river basins in both ecoregions. Additionally, we confirm the occurrence of M. carcinus from Rio Grande do Norte State and provide updated distribution maps for each species in the studied area. This carcinofauna survey may form the basis for future evaluations of eventual anthropic impacts on biological diversity resulting from projects being implemented in these regions, which involve the São Francisco interbasin water transfer.

Ideal vs adapted digital smile diagnosis in multidisciplinary cases during clear aligner treatment.

A digital smile diagnosis based on Digital Smile Design (DSD) concepts reinforces the predictability and precision of orthodontic and multidisciplinary cases as it allows more accurate planning from an esthetic point of view. The intention of this clinical case series was to verify the relationship between the ideal and adapted smile in three orthodontic multidisciplinary cases treated using the Invisalign system in order to have a better understanding of the correlation between the several smile components. The ideal smile construction requires face, lips, gingival tissue, and tooth analysis and evaluation, as well as the appreciation of how all these aspects occur together. When the ideal smile line is not achievable in difficult clinical situations, the treatment goal would be an adaptation to the same line that supports a more predictable movement range. These DSD and orthodontic concepts should be primarily applied, since all intermediate involvement, as well as the final outcomes, are essentially planned from the beginning in clear aligner treatments. The presented case series allowed the authors to understand the importance of these digital diagnostic tools in dealing with certain particularities in orthodontic clear aligner treatments, both at the beginning and during the refinement/finishing stages.

Sleep apnea: before and after heart transplant.

Sleep disorder breathing is a highly prevalent public health problem and is common among patients with cardio and cerebrovascular diseases. Respiratory events are associated with numerous consequences, such as the hyperadrenergic state, known as a predictor of premature mortality in patients with heart failure. On the other hand, reduced stroke volume is associated with fluid retention in patients with heart failure, leading to changes in the upper airflow dynamics. Whether and how to treat sleep disorder breathing enables chronic cardiovascular consequences to be reversed is not fully established. Few cases are known where sleep disordered breathing diagnosis was made several years before heart transplantation. To better understand how does sleep apnea evolve and to ponder about what is the best treatment approach in this context, is the objective with this case presentation.

Quality of life of women who underwent breast cancer treatment relative to sociodemographic, behavioral, and clinical factors

ABSTRACT Objective Patients with cancer often undergo multiple extended treatments that decrease their quality of life. However, the quality of life of women with breast cancer after they undergo treatment remains underexplored in Brazil. Therefore, this study determined sociodemographic, behavioral, and clinical factors related to the post-treatment quality of life of women with breast cancer. Methods This cross-sectional study involved 101 women diagnosed with breast cancer between 2014 and 2016 and treated at a Brazilian Oncology Reference Service. Data were collected from them using face-to-face surveys. Quality of life was evaluated using the European Organization for the Research and Treatment of Cancer Core Quality of Life questionnaire (EORTC QLQ-C30) and EORTC Breast Cancer-specific Quality of Life questionnaire (EORTC QLQ-BR23). The data collected were analyzed using Student's t-test and Mann-Whitney U test. Results The median score on the global health, functional, and symptom scales of the EORTC QLQ-C30 was 75.00 (Interquartile range=33.33), 75.99 (Standard deviation [SD]=19.26), and 19.67 (SD=16.91), respectively. The mean score on the functional and symptom scales of the EORTC QLQ-BR23 was 61.89 (SD=17.21) and 20.12 (SD=16.94), respectively. Furthermore, higher post-treatment quality of life was found to be associated with being aged 50 or more, being Black, having eight or more years of education, having a partner, having a paying job, receiving treatment from the private healthcare system, having a higher income, living in the municipality where healthcare services are availed, engaging in physical activity, not smoking, being more religious, having more social support, not being overweight, having no comorbidities, and undergoing lumpectomy. Conclusion Sociodemographic, behavioral, and clinical factors significantly impact the quality of life of women who undergo breast cancer treatment. Implementing interventions that improve health and reducing inequalities in the access to healthcare services can improve the quality of life of these patients.

[Non-metastatic breast cancer specific-survival of patients after treatment with adjuvant chemotherapy]. / Sobrevida específica de pacientes com câncer de mama não-metastático submetidas à quimioterapia adjuvante.

OBJECTIVE: Analyze the 5-year breast cancer specific-survival rate of women diagnosed with invasive non-metastatic disease, who as part of their primary treatment underwent surgery followed by adjuvant chemotherapy. METHODS: Four hundred twenty eight patients diagnosed between 1998 and 2000 were recruited from all oncology services of the municipality of Juiz de Fora, MG, Brasil. Survival time was counted from the date of the histopathological diagnosis and the date of death due to breast cancer was considered the adverse event. Women alive until December 2005, the final date of the follow-up, were censored. For those who interrupt treatment, censor date was the last follow-up in the medical records. Kaplan-Meier survival curves were estimated, with the differences assessed by the log-rank test. RESULTS: Mean age was 51.2 years, and most (72.6%) were Caucasian. Clinical Stages II (47.4%) and III (38.6%) predominated. Breast cancer specific five-year survival rate was 82.0%. A worst survival was observed among women with disease diagnostic before menopause (p=0.02), with tumor size greater than 2.0 cm (p=0.05), with lymph node involvement (p=0,000), in a more advanced disease stage (p=0.000), on a full adjuvant chemotherapy regimen (p=0.03), and who used hormone therapy (p=0.05). CONCLUSION: This research allowed identification of the profile and disease survival of breast cancer patients who used adjuvant chemotherapy. These results stimulated the adoption of intensive strategies by the local health authorities for disease control and prevention in this population, emphasizing the increasing need of breast cancer screening, mainly for women considered as of high risk and the availability of timely treatment for all cases diagnosed.

[Racial disparity in 10-year breast cancer survival: a mediation analysis using potential responses approach]. / Disparidade racial na sobrevivência em 10 anos para o câncer de mama: uma análise de mediação usando abordagem de respostas potenciais.

The study's objectives were to investigate the association between race/color and 10-year survival in women with breast cancer and the role of staging as mediator. This was a hospital cohort with 481 women with invasive breast cancer diagnosed from 2003 to 2005. Comparisons were made between white and black women as to sociodemographic characteristics and staging, using the chi-square test, and 10-year survival, using Kaplan-Meier and Cox regression methods. For the race/color variable, direct and indirect effects were estimated, mediated by staging, with adjustment for the socioeconomic status of the woman's area of residence and age, using the potential responses (counterfactual) model and Cox multiple regression. Black women living in low-income census tracts were more likely to use the public health care system and to be diagnosed at more advanced stages. Breast cancer-specific 10-year survival was 64.3% (95%CI: 60.0; 68.9), with a significant difference between whites (69.5%; 95%CI: 64.8; 74.6) and blacks (44; 95%CI: 35.2%; 55.1). In the multivariate models adjusted for income and age, black women had worse prognosis (HR = 2.09; 95%CI: 1.76; 2.51), and the proportion mediated by staging was 40% (95%CI: 37; 42). There is racial disparity in 10-year breast cancer survival in Brazilian women, mediated mainly by more advanced staging at diagnosis in black women. This highlights the need to expand both the coverage and the quality of breast cancer screening and to facilitate access to early diagnosis and treatment in order to reduce racial inequality.

Os objetivos foram investigar a associação entre raça/cor e a sobrevivência em 10 anos de mulheres com câncer de mama e o papel do estadiamento como mediador. Coorte hospitalar com 481 mulheres com câncer invasivo de mama, diagnosticadas entre 2003 e 2005. Foram feitas comparações entre mulheres brancas e negras quanto às características sociodemográficas e ao estadiamento, usando o teste qui-quadrado, e à sobrevivência em 10 anos, usando os métodos de Kaplan-Meier e regressão de Cox. Foram estimados para a variável raça/cor efeitos diretos e indiretos, mediados pelo estadiamento, com ajuste para a condição social da área de residência e idade, utilizando o modelo de respostas potenciais (contrafactual) e regressão múltipla de Cox. As mulheres negras residiam em setores censitários de menor renda, eram usuárias do setor público em maior proporção e foram diagnosticadas com estadiamentos mais avançados. A sobrevivência específica em 10 anos foi de 64,3% (IC95%: 60,0; 68,9), com diferença significativa entre brancas (69,5%; IC95%: 64,8; 74,6) e negras (44%; IC95%: 35,2; 55,1). Nos modelos múltiplos, ajustados para renda e idade, as negras tiveram pior prognóstico (HR = 2,09; IC95%: 1,76; 2,51), e a proporção mediada pelo estadiamento foi de 40% (IC95%: 37; 42). Há disparidade racial na sobrevivência do câncer de mama em 10 anos, mediada principalmente pelo estadiamento mais avançado da doença nas mulheres negras. Isso aponta para a necessidade de ampliar a cobertura e a qualidade do programa de rastreamento dessa doença e facilitar o acesso ao diagnóstico e tratamento precoces, com vistas à redução da iniquidade racial.

Los objetivos fueron investigar la asociación entre raza/color y la supervivencia en 10 años de mujeres con cáncer de mama y el papel de la fase de desarrollo como mediador. Se trata de una cohorte hospitalaria de 481 mujeres, con cáncer invasivo de mama, diagnosticadas entre 2003 y 2005. Se realizaron comparaciones entre mujeres blancas y negras, en cuanto a las características sociodemográficas y a la fase del cáncer, usando el test chi-quadrado, y la supervivencia en 10 años, usando los métodos de Kaplan-Meier y regresión de Cox. Se estimaron para la variable raza/color efectos directos e indirectos, mediados por las diferentes fases, con ajuste en la condición social del área de residencia y edad, utilizando el modelo de respuestas potenciales (contrafactual) y regresión múltiple de Cox. Las mujeres negras residían en sectores censitarios de menor renta, eran usuarias del sector público en mayor proporción y fueron diagnosticadas en fases más avanzadas. La supervivencia específica en 10 años fue de un 64,3% (IC95%: 60,0; 68,9), con una diferencia significativa entre blancas (69,5%; IC95%: 64,8%-74,6%) y negras (44%; IC95%: 35,2; 55,1). En los modelos múltiples, ajustados para renta y edad, las negras tuvieron un peor pronóstico (HR = 2,09; IC95%: 1,76-2,51), y la proporción mediada por el estadio fue de un 40% (IC95%: 37; 42). Existe disparidad racial en la supervivencia del cáncer de mama en 10 años, mediada principalmente por el estadio más avanzado de la enfermedad en las mujeres negras. Esto apunta la necesidad de ampliar la cobertura y calidad del programa de rastreo de esa enfermedad y facilitar el acceso al diagnóstico y tratamiento precoces, con vistas a la reducción de la inequidad racial.

(Re)Descobrindo a teoria fundamentada para a pesquisa em enfermagem: reflexões sobre a vertente relativista / (Re)discovering the grounded theory for research in nursing: reflections on the relativist strand / (Re)Descubriendo la teoría fundamentada para la investigación en enfermería: reflexiones sobre la corriente relativista

Objetivo: descrever e analisar criticamente a vertente relativista da Teoria fundamentada nos dados (TFD), incluindo uma abordagem de como utilizar este referencial metodológico nas pesquisas qualitativas em enfermagem. Conteúdo: estudo teórico reflexivo organizado em três tópicos. Primeiramente apresenta a evolução da TFD e o legado straussiano; na sequência as características metodológicas da vertente relativista e, por fim, as contribuições da TFD relativista para as pesquisas em enfermagem brasileira. Considerações finais: trata-se de um referencial apropriado para estudos na enfermagem, por possibilitar a geração de modelos explicativos, a partir da prática de enfermagem, e por fornecer subsídios para os profissionais de saúde refletirem sobre o seu fazer com vistas a otimizar a qualidade do cuidado.

Objective: to describe and critically analyze the relativistic aspect of Grounded Theory (GT), also addressing how to use this methodological framework in qualitative research in Nursing. Content: this reflective, theoretical study was organized into three topics: first, the evolution of GT and the legacy of Strauss; then, the methodological characteristics of the relativistic approach; and, finally, the contributions of relativist GT to Brazilian Nursing research. Final considerations: this framework is appropriate for nursing studies, as it makes it possible to generate explanatory models based on nursing in practice and provides input for health personnel to reflect on their own practice, in order to optimize the quality of care.
