RESUMEN
The main objective of this secondary analysis was to describe the nutritional status of the Better Outcomes in Labour Difficulty (BOLD) project study population and determine possible associations between maternal nutritional status (as reflected by maternal BMI at the time of birth) and severe neonatal outcomes (SNO). We also analysed previous and index maternal pathologies to determine associations with neonatal outcomes. We used the classification designed by Atalah for maternal BMI and compared with the Hyperglycaemia and Adverse Pregnancy Outcome study one. To describe the nutritional status of this population, figures of distribution and test of normality related to weight and BMI were presented for the women and their babies. To explore the association between maternal BMI data and SNO, the χ2 test was performed. To identify a maternal characteristic or a group of characteristics that could predict SNO, we used Fisher's exact test using previous maternal pathology collected in the BOLD project as well as that in the index pregnancy. In this study, BMI at the time of birth was not associated with neonatal near miss or death. We found that previous maternal obesity, diabetes and chronic hypertension were associated with SNO. Maternal pathology in the index pregnancy such as other obstetric haemorrhage, pre-eclampsia, anaemia and gestational diabetes was associated with SNO.

BACKGROUND: Caesarean section is recommended in situations in which vaginal birth presents a greater likelihood of adverse maternal or perinatal outcomes than normal. However, it is associated with a higher risk of complications, especially when performed without a clear medical indication. Since labour attendants have no standardised clinical method to assist in this decision, statistical tools developed based on multiple labour variables may be an alternative. The objective of this paper was to develop and evaluate the accuracy of models for caesarean section prediction using maternal and foetal characteristics collected at admission and through labour. METHOD: This is a secondary analysis of the World Health Organization's Better Outcomes in Labour Difficulty prospective cohort study in two sub-Saharan African countries. Data were collected from women admitted for labour and childbirth in 13 hospitals in Nigeria as well as Uganda between 2014 and 2015. We applied logistic regression to develop different models to predict caesarean section, based on the time when intrapartum assessment was made. To evaluate discriminatory capacity of the various models, we calculated: area under the curve, diagnostic accuracy, positive predictive value, negative predictive value, sensitivity and specificity. RESULTS: A total of 8957 pregnant women with 12.67% of caesarean births were used for model development. The model based on labour admission characteristics showed an area under the curve of 78.70%, sensitivity of 63.20%, specificity of 78.68% and accuracy of 76.62%. On the other hand, the models that applied intrapartum assessments performed better, with an area under the curve of 93.66%, sensitivity of 80.12%, specificity of 89.26% and accuracy of 88.03%. CONCLUSION: It is possible to predict the likelihood of intrapartum caesarean section with high accuracy based on labour characteristics and events. However, the accuracy of this prediction is considerably higher when based on information obtained throughout the course of labour.

BACKGROUND: Escalation in the global rates of labour interventions, particularly cesarean section and oxytocin augmentation, has renewed interest in a better understanding of natural labour progression. Methodological advancements in statistical and computational techniques addressing the limitations of pioneer studies have led to novel findings and triggered a re-evaluation of current labour practices. As part of the World Health Organization's Better Outcomes in Labour Difficulty (BOLD) project, which aimed to develop a new labour monitoring-to-action tool, we examined the patterns of labour progression as depicted by cervical dilatation over time in a cohort of women in Nigeria and Uganda who gave birth vaginally following a spontaneous labour onset. METHODS AND FINDINGS: This was a prospective, multicentre, cohort study of 5,606 women with singleton, vertex, term gestation who presented at ≤ 6 cm of cervical dilatation following a spontaneous labour onset that resulted in a vaginal birth with no adverse birth outcomes in 13 hospitals across Nigeria and Uganda. We independently applied survival analysis and multistate Markov models to estimate the duration of labour centimetre by centimetre until 10 cm and the cumulative duration of labour from the cervical dilatation at admission through 10 cm. Multistate Markov and nonlinear mixed models were separately used to construct average labour curves. All analyses were conducted according to three parity groups: parity = 0 (n = 2,166), parity = 1 (n = 1,488), and parity = 2+ (n = 1,952). We performed sensitivity analyses to assess the impact of oxytocin augmentation on labour progression by re-examining the progression patterns after excluding women with augmented labours. Labour was augmented with oxytocin in 40% of nulliparous and 28% of multiparous women. The median time to advance by 1 cm exceeded 1 hour until 5 cm was reached in both nulliparous and multiparous women. Based on a 95th percentile threshold, nulliparous women may take up to 7 hours to progress from 4 to 5 cm and over 3 hours to progress from 5 to 6 cm. Median cumulative duration of labour indicates that nulliparous women admitted at 4 cm, 5 cm, and 6 cm reached 10 cm within an expected time frame if the dilatation rate was ≥ 1 cm/hour, but their corresponding 95th percentiles show that labour could last up to 14, 11, and 9 hours, respectively. Substantial differences exist between actual plots of labour progression of individual women and the 'average labour curves' derived from study population-level data. Exclusion of women with augmented labours from the study population resulted in slightly faster labour progression patterns. CONCLUSIONS: Cervical dilatation during labour in the slowest-yet-normal women can progress more slowly than the widely accepted benchmark of 1 cm/hour, irrespective of parity. Interventions to expedite labour to conform to a cervical dilatation threshold of 1 cm/hour may be inappropriate, especially when applied before 5 cm in nulliparous and multiparous women. Averaged labour curves may not truly reflect the variability associated with labour progression, and their use for decision-making in labour management should be de-emphasized.

Background: The near miss concept, denoting near collisions between aircraft, originated in aeronautics, but has recently been transferred to the neonatal context as a way of evaluating the quality of health services for newborns, especially in settings with reduced child mortality. However, there is yet no consensus regarding the underlying criteria. The most common indicators used to assess health care quality include mortality (maternal and neonatal) and life-threatening conditions. Using the World Health Organization (WHO) Better Outcomes in Labour Difficulty (BOLD) prospective cohort study data set, we conducted a secondary analysis to validate the near miss concept and explore the association between maternal and neonatal outcomes. Methods: We studied 10 203 singleton mothers treated between December 2014 and November 2015 in nine Nigerian and four Ugandan hospitals. We validated the near miss concept by testing the diagnostic accuracy (sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and odds ratio (OR)) using death as the reference variable and calculating the maternal and neonatal case fatality rates. We performed ordinal and binomial logistic regression, with the independent variables being those that had P < 0.1 in the univariate analyses. We considered the significance level of 5%. Results: We validated the neonatal near miss concept using the BOLD study data. We observed maternal and neonatal case fatality rates of 70.2% and 6.5%, with an increasing severity relationship between maternal and neonatal outcomes (P < 0.05). Ordinal logistic regression showed that gestational age <37 or >41 weeks and <8 antenatal consultations were related to a higher risk of neonatal severe outcomes, while maternal age between 30 and 34 years functioned as a protective factor against severe neonatal outcomes (SNO). Binomial logistic regression showed gestational age <37(OR = 1.46; 95% confidence interval (CI) = 1.07-1.94) or >41 weeks (OR = 2.26; 95% CI = 1.55-3.20), low educational level (OR = 1.76; 95% CI = 1.12-2.69), overweight/obesity (OR = 1.23; 95% CI = 1.02-1.47), one previous cesarean section (OR = 1.90; 95% CI = 1.36-2.61), one previous abortion (OR = 1.25; 95% CI = 1.00-1.56), and previous chronic condition (OR = 1.83; 95% CI = 1.37-2.41) were risk factors for SNO. Conclusions: The neonatal near miss concept could be used as a parameter for analysis in different health systems, to ensure that measuring of neonatal severity is comparable across health care units. In this analysis, we observed a progressive association between maternal severity and the severity of the newborns' outcomes.

BACKGROUND: Cases of coronavirus disease 2019 (COVID-19) requiring hospitalization continue to appear in vulnerable populations, highlighting the importance of novel treatments. The hyperinflammatory response underlies the severity of the disease, and targeting this pathway may be useful. Herein, we tested whether immunomodulation focusing on interleukin (IL)-6, IL-17, and IL-2, could improve the clinical outcomes of patients admitted with COVID-19. METHODS: This multicenter, open-label, prospective, randomized controlled trial was conducted in Brazil. Sixty hospitalized patients with moderate-to-critical COVID-19 received in addition to standard of care (SOC): IL-17 inhibitor (ixekizumab 80 mg SC/week) 1 dose every 4 weeks; low-dose IL-2 (1.5 million IU per day) for 7 days or until discharge; or indirect IL-6 inhibitor (colchicine) orally (0.5 mg) every 8 hours for 3 days, followed by 4 weeks at 0.5 mg 2x/day; or SOC alone. The primary outcome was accessed in the "per protocol" population as the proportion of patients with clinical improvement, defined as a decrease greater or equal to two points on the World Health Organization's (WHO) seven-category ordinal scale by day 28. RESULTS: All treatments were safe, and the efficacy outcomes did not differ significantly from those of SOC. Interestingly, in the colchicine group, all participants had an improvement of greater or equal to two points on the WHO seven-category ordinal scale and no deaths or patient deterioration were observed. CONCLUSIONS: Ixekizumab, colchicine, and IL-2 were demonstrated to be safe but ineffective for COVID-19 treatment. These results must be interpreted cautiously because of the limited sample size.

This paper aims to discuss the Bayesian estimation approach for the zero-inflated cure class of models, which extends the standard cure model by accommodating zero-inflated data in the survival analysis context. A comprehensive simulation study is carried out to assess the performance of the estimation procedure. A new estimation methodology is illustrated using a real dataset related to women diagnosed with invasive cervical cancer in Brazil.
RESUMEN
In obstetrics and gynecology, knowledge about how women's features are associated with childbirth is important. This leads to establishing guidelines and can help managers to describe the dynamics of pregnant women's hospital stays. Then, time is a variable of great importance and can be described by survival models. An issue that should be considered in the modeling is the inclusion of women for whom the duration of labor cannot be observed due to fetal death, generating a proportion of times equal to zero. Additionally, another proportion of women's time may be censored due to some intervention. The aim of this paper was to present the Log-Normal zero-inflated cure regression model and to evaluate likelihood-based parameter estimation by a simulation study. In general, the inference procedures showed a better performance for larger samples and low proportions of zero inflation and cure. To exemplify how this model can be an important tool for investigating the course of the childbirth process, we considered the Better Outcomes in Labor Difficulty project dataset and showed that parity and educational level are associated with the main outcomes. We acknowledge the World Health Organization for granting us permission to use the dataset.
RESUMEN
BACKGROUND: We aimed to evaluate the impact of providing dental care to critically ill patients on their risk of death and ventilator-associated pneumonia (VAP). METHODS: A quasi-experimental study was conducted in 2 intensive care units (ICU) from 2016 to 2019. The intervention consisted of implementing routine dental care, focusing on oral hygiene and periodontal treatment, at least 3 times a week, for patients admitted to the study units. In the pre-intervention period, routine oral hygiene was provided by the ICU nursing staff. The primary and secondary study outcomes were mortality, evaluated at the end of the ICU stay, and VAP incidence density, respectively. Data were analyzed using the ARIMA (autoregressive integrated moving average) time series model in R software. RESULTS: During the intervention period, 5,147 dental procedures were performed among 355 patients. The time series showed that ICU mortality was 36.11%, 32.71%, and 32.30% within the 3 years before the intervention, and 28.71% during the intervention period (P = .015). VAP incidence density did not significantly change during the study period (P = .716). CONCLUSION: A dental care intervention focused on oral hygiene and periodontal treatment regularly provided by dentists to critically ill patients may decrease their risk of dying in the ICU. Randomized clinical trials should be performed to confirm these findings. TRIAL REGISTRATION: WHO-affiliated Brazilian Clinical Trials Registry. RBR-4jmz36.

Long-term survivor models have been extensively used for modelling time-to-event data with a significant proportion of patients who do not experience poor outcome. In this paper, we propose a new long-term survivor hazard model, which accommodates comprehensive families of cure rate models as particular cases, including modified Weibull, exponentiated Weibull, Weibull, exponential and Rayleigh distribution, among others. The maximum likelihood estimation procedure is presented. A simulation study evaluates bias and mean square error of the considered estimation procedure as well as the coverage probabilities of the parameters asymptotic and bootstrap confidence intervals. A real Brazilian dataset on breast cancer illustrates the methodology. From the practical point of view, under our modelling, we provide a parameter that works as a metric to quantify and compare the risk between different stages of the disease. We emphasize that, we developed an online platform for oncologists to calculate the probability of survival of patients diagnosed with breast cancer according to the stage of the disease in real time.

OBJECTIVE: To evaluate the effectiveness of dental treatment in improving oral health in critical patients. METHODS: This randomised clinical trial was conducted in a general intensive care unit (ICU) at a tertiary care public facility from 1 January 2011 to 8 August 2013. Data from 254 adult patients staying in the ICU for 48 hours or more were analysed. The experimental group (n = 127) had access to dental treatment provided by a dentist four to five times a week, in addition to routine oral hygiene, whereas the control group (n = 127) had access only to routine oral hygiene, including topical application of chlorhexidine, provided by the ICU nursing staff. The baseline oral health status of the enrolled patients was poor and included edentulism, caries, gingivitis, periodontitis and residual roots. Dental treatment consisted of toothbrushing, tongue scraping, removal of calculus, scaling and root planing, caries restoration and tooth extraction. RESULTS: The Oral Hygiene Index Simplified (OHI-S) and Gingival Index (GI) scores decreased in the experimental group but did not change significantly in the control group during the ICU stay. Dental treatment prevented most of the episodes of respiratory tract infections, as previously reported. No severe adverse events from the dental treatment were observed. CONCLUSION: From an interprofessional perspective, our results support the idea of including dentists in the ICU team to improve oral health in critical patients and effectively prevent respiratory tract infections, in addition to the improvement achievable by applying chlorhexidine alone.

RESUMEN
OBJECTIVE: To correlate blood transfusions and clinical outcomes during hospitalization in coronary artery bypass grafting surgery (CABG). METHODS: Transfusion, clinical and hematological data were collected for 1,378 patients undergoing isolated or combined CABG between January 2011 and December 2012. The effect of blood transfusions was evaluated through multivariate analysis to predict three co-primary outcomes: composite ischemic events, composite infectious complications and hospital mortality. Because higher risk patients receive more transfusions, the hospital mortality outcome was also tested on a stratum of low-risk patients to isolate the effect of preoperative risk on the results. RESULTS: The transfusion rate was 63.9%. The use of blood products was associated with a higher incidence of the three coprimary outcomes: composite infectious complications (OR 2.67, 95% CI 1.70 to 4.19; P<0.001), composite ischemic events (OR 2.42, 95% CI 1.70 to 3.46; P<0.001) and hospital mortality (OR 3.07, 95% CI 1.53 to 6.13; P<0.001). When only patients with logistic EuroSCORE ≤ 2% were evaluated, i.e., low-risk individuals, the mortality rate and the incidence of ischemic events and infectious complications composites remained higher among the transfused patients [6% vs. 0.4% (P<0.001), 11.7% vs. 24,3% (P<0.001) and 6.5% vs. 12.7% (P=0.002), respectively]. CONCLUSION: The use of blood components in patients undergoing CABG was associated with ischemic events, infectious complications and hospital mortality, even in low-risk patients.

Heart rate variability (HRV) analysis is a useful method to assess abnormal functioning in the autonomic nervous system and to predict cardiac events in patients with heart failure (HF). HRV measurements with heart rate monitors have been validated with an electrocardiograph in healthy subjects but not in patients with HF. We explored the reproducibility of HRV in two consecutive six-minute walk tests (6MW), 60-minute apart, using a heart rate monitor (PolarS810i) and a portable electrocardiograph (called Holter) in 50 HF patients (mean age 59 years, NYHA II, left ventricular ejection fraction ~35%). The reproducibility for each device was analysed using a paired t-test or the Wilcoxon signed-rank test. Additionally, we assessed the agreement between the two devices based on the HRV indices at rest, during the 6MW and during recovery using concordance correlation coefficients (CCC), 95% confidence intervals and Bland-Altman plots. The test-retest for the HRV analyses was reproducible using Holter and PolarS810i at rest but not during recovery. In the second 6MW, patients showed significant increases in rMSSD and walking distance. The PolarS810i measurements had remarkably high concordance correlation [0.86Asunto(s)

RESUMEN
PURPOSE: To validate the instrument Body Image Relationship Scale (BIRS) for Brazilian women with breast cancer. METHODS: The instrument was administered by trained interviewers to 139 women who used the Brazilian Unified Health System (SUS). All of them had been submitted to cancer treatments between 2006 and 2010. The instrument was validated considering internal consistency and reliability. In order to compare the techniques, the same factorial analysis as used in the original paper was carried out. RESULTS: The Spearman-Brown correlation value was 0.8, indicating high internal reliability. The Cronbach's alpha found was 0.9, indicating a high level of internal consistency. Factorial analysis showed that four items had low factorial load and no discriminatory power, and another five items were relocated to other factors. When the instrument was applied, it showed variability to that of the original instrument. CONCLUSION: The Brazilian version of the Body Image Relationship Scale (BIRS), named Escala de Relacionamento e Imagem Corporal (ERIC), showed evidence of adequate reliability and internal consistency, making this instrument suitable to be recommended for application to Brazilian women with breast cancer, despite some limitations.

Abstract Background Contextual factors involving the physical and social environment, as well as personal factors, are closely related to functional status, and they can have positive or negative influences on the health conditions or status of an individual in society. Objectives The objective is to evaluate the effect of a mindfulness-based intervention program on functional status and mindfulness levels in primary health care (PHC) professionals in Ribeirão Preto, Brazil. Methods This is a quasi-experimental study, with 26 PHC professionals, using quantitative methods and an analytical before and after approach of an 8-week mindfulness program. Results There were significant differences in mindfulness facets after the intervention: Observe (p = 0.002); Describe - positive formulation (p = 0.01); Acting with awareness - automatic pilot (p = 0.01) and distraction (p = 0.05); Nonreactivity (p = 0.0005); Nonjudgement (p = 0.01); and in total mindfulness scores (p = 0.0000018). Regarding functional status, significant differences were found: change in health (p = 0.01), overall health (p = 0.007), quality of life (p = 0.04) and feelings (p = 0.01). Discussion The results in improving the functional status and mindfulness of PHC professionals show that mindfulness practices can improve the worker's quality of life and health.

PURPOSE: To understand the reproductive and sexual life of women treated for breast cancer. METHODS: A total of 139 women with a diagnosis made at least 6 months ago were interviewed after being randomly selected in a rehabilitation service. The interviews were carried out between 2006 and 2010. The inclusion criteria were: to have used a rehabilitation service between 2006 and 2010, to be a Unified Health System user, to have been a patient at a regional hospital and to be resident in the area of DRS XIII-Ribeirão Preto, state of São Paulo. The interviewees were visited at home where a face to face questionnaire regarding sociodemographic features and questions about the disease and reproductive and sexual life was administered. For the last one, the Female Sexual Function Index instrument was used. Data were analyzed statistically by the χ² test, Fisher exact test, Student's t test, multivariate analysis by logistic regression, factorial analysis and the Cronbach's alpha. RESULTS: Most patients had between 2 to 3 children and 80% used some contraceptive. About half of them had had sexual intercourse in the last month, 45.3% had interrupted sexual intercourse during treatment and 25.9% did not. There were reports of decreasing sexual activity, although half of the interviewees had re-started sexual life during the first six months after treatment. About half presented sexual dissatisfaction. An active sexual life is associated with being younger than 40 years of age and to have a partner. No association was found between active sexual life and diagnosis and types of treatment. CONCLUSION: Sexual activity of women treated for breast cancer is not associated with the treatments, but with age and with the opportunity of having sex.

BACKGROUND: KRAS gene mutations play an important role in the carcinogenesis of colorectal tumors. However, studies that have assessed the association between KRAS gene mutation status and disease characteristics report conflicting results. To assess KRAS gene status (mutated or wild-type) and its association with the clinical, epidemiological, and histopathological features of metastatic colorectal adenocarcinoma as well its association with clinical outcomes. METHODS: Cross-sectional descriptive study in which clinical and histopathological data were collected from the medical records of 65 patients diagnosed with metastatic colorectal adenocarcinoma at the Clinical Oncology Service of the Teaching Hospital of the School of Medicine of Ribeirao Preto, University of Sao Paulo (Hospital das Clinicas da Faculdade de Medicina de Ribeirao Preto, Universidade de Sao Paulo -HCFMRP-USP) between 2005 and 2012 and analyzed based on their KRAS gene status. RESULTS: KRAS gene mutations were found in 49.2% of the tumors, and G/A (25.5%) and Gly12Asp (34.37%) were the most frequent mutations. Among the investigated clinical features (gender, ECOG (Eastern Cooperative Oncology Group), histology, degree of cell differentiation, lymph node ratio, primary tumor site, staging, presence of synchronous metastasis, lung metastasis, and liver metastasis), the association between age less than 65 years with KRAS mutation was statistically significant (P = 0.046). KRAS mutation status did not exhibit a significant correlation with the overall survival of the patients (P = 0.078); however, the cases with KRAS mutation exhibited shorter survival. In the multivariate analysis, synchronous metastasis (P = 0.03) and liver metastasis (P = 0.008) behaved as independent factors of poor prognosis relative to the overall survival of the patients. CONCLUSION: The KRAS mutation status did not exhibit prognostic value in the investigated sample. Among the older patients (> 65 years old), wild-type KRAS was more frequently observed compared to mutated KRAS.

All of them had been submitted to cancer treatments between 2006 and 2010. The instrument was validated considering internal consistency and reliability. In order to compare the techniques, the same factorial analysis as used in the original paper was carried outRESULTSThe Spearman-Brown correlation value was 0.8, indicating high internal reliability. The Cronbach's alpha found was 0.9, indicating a high level of internal consistency. Factorial analysis showed that four items had low factorial load and no discriminatory power, and another five items were relocated to other factors. When the instrument was applied, it showed variability to that of the original instrumentCONCLUSIONThe Brazilian version of the Body Image Relationship Scale (BIRS), namedEscala de Relacionamento e Imagem Corporal (ERIC), showed evidence of adequate reliability and internal consistency, making this instrument suitable to be recommended for application to Brazilian women with breast cancer, despite some limitations.

OBJETIVO: Compreender a vida sexual e reprodutiva de mulheres tratadas de câncer de mama. MÉTODOS: Foram entrevistadas 139 mulheres com diagnóstico há pelo menos seis meses, selecionadas aleatoriamente em um serviço de reabilitação. As entrevistas foram feitas entre 2006 e 2010. Todas eram usuárias do SUS, pacientes de um hospital regional e moradoras da região DRS XIII-Ribeirão Preto, Estado de São Paulo. As entrevistadas foram visitadas em seu domicílio onde foi aplicado um questionário face a face que abordava questões relativas às características sociodemográficas, da doença e da vida reprodutiva e sexual, para esta última aplicou-se o instrumento Índice de Função Sexual Feminina (IFSF). A análise estatística incluiu o teste do χ², o teste exato de Fisher e o teste t de Student, análise multivariada por regressão logística e análise fatorial e alfa de Cronbach. RESULTADOS: A maioria teve entre 2 e 3 filhos e 80% utilizaram algum método anticoncepcional. Cerca de metade das mulheres tiveram relação sexual no último mês, 45,3% interromperam as relações sexuais durante o tratamento e 25,9% não interromperam. Houve relato de diminuição da frequência sexual, embora metade das entrevistadas tenha retomado a vida sexual nos primeiros seis meses após o tratamento. Pouco mais de metade apresentou insatisfação sexual. Encontrou-se vida sexual ativa associada à idade menor que 40 anos e a ter parceiro. Não foi encontrada associação entre vida sexual ativa e ao diagnóstico e tipos de tratamento. CONCLUSÃO: A atividade sexual de mulheres tratadas para câncer de mama não está associada aos tratamentos, mas à idade e à oportunidade de ter sexo.
PURPOSE: To understand the reproductive and sexual life of women treated for breast cancer. METHODS: A total of 139 women with a diagnosis made at least 6 months ago were interviewed after being randomly selected in a rehabilitation service. The interviews were carried out between 2006 and 2010. The inclusion criteria were: to have used a rehabilitation service between 2006 and 2010, to be a Unified Health System user, to have been a patient at a regional hospital and to be resident in the area of DRS XIII-Ribeirão Preto, state of São Paulo. The interviewees were visited at home where a face to face questionnaire regarding sociodemographic features and questions about the disease and reproductive and sexual life was administered. For the last one, the Female Sexual Function Index instrument was used. Data were analyzed statistically by the χ² test, Fisher exact test, Student's t test, multivariate analysis by logistic regression, factorial analysis and the Cronbach's alpha. RESULTS: Most patients had between 2 to 3 children and 80% used some contraceptive. About half of them had had sexual intercourse in the last month, 45.3% had interrupted sexual intercourse during treatment and 25.9% did not. There were reports of decreasing sexual activity, although half of the interviewees had re-started sexual life during the first six months after treatment. About half presented sexual dissatisfaction. An active sexual life is associated with being younger than 40 years of age and to have a partner. No association was found between active sexual life and diagnosis and types of treatment. CONCLUSION: Sexual activity of women treated for breast cancer is not associated with the treatments, but with age and with the opportunity of having sex.
