Abstract The scope of this article is to analyze the compliance of the care offered by Casa de Parto David Capistrano Filho-RJ with the recommendations of the National Guidelines for Care in Natural Childbirth. It involved a descriptive cross-sectional study with 952 observations, from 2014 to 2018. This included analysis of compliance using a judgment matrix and then classified as total compliance (≥75.0%), partial compliance (50.0%-74.9%), incipient compliance (49.9%-25.0%) and non-compliance (less than 24.9%). The results of the judgment matrix show that care in the aspects of labor, delivery and newborn care is in full compliance with the recommendations of the Guidelines. The care at the Casa de Parto Birth Center, conducted by obstetric nurses, follows the recommendations of the national guidelines, and has been seen to incorporate a de-medicalized, personalized form of care, which respects the physiology of childbirth. They also develop a model of their own technologies of care, constituting non-invasive technologies of obstetric nursing care.

Abstract The presented development is an intelligent diagnostic system for transformers that studied machine learning techniques to determine the operational status of these transformers. The study of these techniques is initiated by observing the quantities that define the operational behavior of large transformers, aiming to identify anomalies in their operation from data from sensors that equipment it in the functioning environment. This large power transformer has a theoretical service life of above 20 years and a low failure rate. Thus, obtaining failure values, which have their evolution monitored for large transformers, is almost nil. Therefore, a supervised machine training methodology to diagnose these cases is practically unfeasible. The study carried out with several traditional intelligent techniques can verify this. Several supervised methods (Closest Neighbor K-th Neighbor, Support Vector Machine, Radial Base Function, Decision Trees, Random Forest, Neural Network, AdaBoost, Gaussian Naive Bayes, and Quadratic Discriminant Analysis) were studied.

Abstract Background Religiosity and spirituality have been associated with higher recovery rates, greater adherence to treatments, and better levels of quality of life in patients with heart disease. Objectives To evaluate the association between spirituality, functional gain, and improved quality of life in patients in a cardiovascular rehabilitation program. Methods This prospective cohort study evaluated the association between functional and quality of life gains during a cardiovascular rehabilitation program and a religiosity/spirituality index based on a validated scale. Depression, anxiety, and stress symptoms were screened for control purposes. P values < 0.05 were considered significant for all analyses. Results The study followed 57 patients (66 ± 12 years old; 71.7% male; 76% with coronary artery disease). The Spearman correlation coefficient did not show any associations between increases in functional capacity and organizational (rs = 0.110; p = 0.421), non-organizational (rs = −0.007; p = 0.421), or intrinsic (rs = −0.083; p = 0.543) religiosity. Furthermore, no associations were detected between the results of a quality of life score and organizational (rs = 0.22; p = 0.871), non-organizational (rs = 0.191; p = 0.159), or intrinsic (rs = 0.108; p = 0.429) religiosity. Conclusion No association was detected between functional and quality of life gains and organizational, non-organizational, or intrinsic religiosity in this sample of patients undergoing cardiovascular rehabilitation.

Resumo Fundamento Religiosidade e espiritualidade têm sido associadas a maiores taxas de recuperação, maior adesão a tratamentos e melhores níveis de qualidade de vida em pacientes cardiopatas. Objetivos Avaliar a associação entre espiritualidade, ganho funcional e melhoria de qualidade de vida em pacientes de um programa de reabilitação cardiovascular. Métodos Estudo de coorte prospectiva, no qual foi avaliada a associação entre os ganhos funcional e em qualidade de vida obtidos durante um programa de reabilitação cardiovascular e o índice de religiosidade/espiritualidade a partir de escala validada. Sintomas de depressão, ansiedade e estresse foram rastreados, para fins de controle. Um p < 0,05 foi adotado como padrão significante para todas as análises. Resultados Foram acompanhados 57 pacientes (66 ± 12 anos; 71,7% masculinos, 76% com doença arterial coronariana). O cálculo do coeficiente de correlação de Spearman não evidenciou associações entre incrementos na capacidade funcional e religiosidade organizacional (rs = 0,110; p = 0,421), não organizacional (rs = −0,007; p = 0,421) ou intrínseca (rs = −0,083; p = 0,543). Também não foram detectadas associações entre os resultados de um escore de qualidade de vida e religiosidade organizacional (rs = 0,22; p = 0,871), não organizacional (rs = 0,191; p = 0,159) ou intrínseca (rs = 0,108; p = 0,429). Conclusão Não foi detectada associação entre ganho funcional ou em qualidade de vida e religiosidade organizacional, não organizacional ou intrínseca, nesta amostra de pacientes em reabilitação cardiovascular.

Abstract Background Our aim was to compare the efficacy of rituximab, tocilizumab, and abatacept in individuals with rheumatoid arthritis (RA) refractory to treatments with MTX or TNFi agents. Methods We searched 6 databases until January 2023 for phase 2–4 RCTs evaluating patients with RA refractory to MTX or TNFi therapy treated with rituximab, abatacept, and tocilizumab (intervention arm) compared to controls. Study data were independently assessed by two investigators. The primary outcome was considered as achieving ACR70 response. Results The meta-analysis included 19 RCTs, with 7,835 patients and a mean study duration of 1.2 years. Hazard ratios for achieving an ACR70 response at six months were not different among the bDMARDs, however, we found high heterogeneity. Three factors showing a critical imbalance among the bDMARD classes were identified: baseline HAQ score, study duration, and frequency of TNFi treatment in control arm. Multivariate meta-regression adjusted to these three factors were conducted for the relative risk (RR) for ACR70. Thus, heterogeneity was attenuated (I2 = 24%) and the explanatory power of the model increased (R2 = 85%). In this model, rituximab did not modify the chance of achieving an ACR70 response compared to abatacept (RR = 1.773, 95%CI 0.113–10.21, p = 0.765). In contrast, abatacept was associated with RR = 2.217 (95%CI 1.554–3.161, p < 0.001) for ACR70 compared to tocilizumab. Conclusion We found high heterogeneity among studies comparing rituximab, abatacept, and tocilizumab. On multivariate metaregressions, if the conditions of the RCTs were similar, we estimate that abatacept could increase the chance of reaching an ACR70 response by 2.2-fold compared to tocilizumab. Key messages Abatacept could increase the chance of reaching an ACR70 response by 2.2-fold compared to tocilizumab.

Resumo Fundamento A classificação funcional da New York Heart Association (NYHA) é o sistema de classificação mais utilizado para a insuficiência cardíaca (IC), enquanto o teste de exercício cardiopulmonar (TECP) é o padrão ouro para a avaliação do estado funcional na IC. Objetivo Analisar a correlação e a concordância entre as classes da NYHA e as variáveis do TECP. Métodos Foram selecionados pacientes com IC com indicação clínica para TECP e fração de ejeção (FE) < 50%. A correlação (coeficiente de Spearman) e a concordância (kappa) entre a classificação da NYHA e as classificações baseadas no TECP foram analisadas. Um valor de p < 0,05 foi considerado significativo. Resultados No total, foram incluídos 244 pacientes no estudo. A idade média foi de 56±14 anos, e a FE média foi de 35,5%±10%. A distribuição de pacientes de acordo com a classificação da NYHA foi a seguinte: classe I (31,2%), classe II (48,3%), classe III (19,2%) e classe IV (1,3%). A correlação (r) entre as classes da NYHA e de Weber foi de 0,489 (p < 0,001), e a concordância foi de 0,231 (p < 0,001). A correlação (r) entre as classes da NYHA e ventilatórias (inclinação da ventilação minuto/produção de dióxido de carbono [VE/VCO2]) foi de 0,218 (p < 0,001), e a concordância foi de 0,002 (p = 0,959). A correlação de Spearman entre as classes da NYHA e do escore TECP foi de 0,223 (p = 0,004), e a concordância kappa foi de 0,027 (p = 0,606). Conclusão Foi identificada uma associação moderada entre as classes da NYHA e de Webber, embora a concordância tenha sido baixa. As classes ventilatórias (inclinação VE/VCO2) e do escore TECP apresentaram uma associação fraca e uma baixa concordância com as classes da NYHA.

Abstract Background The New York Heart Association (NYHA) functional classification is the most commonly used classification system for heart failure (HF), whereas cardiopulmonary exercise testing (CPET) is the gold standard for functional status evaluation in HF. Objective This study aimed to analyze correlation and concordance between NYHA classes and CPET variables. Methods HF patients with clinical indication for CPET and ejection fraction (EF) < 50% were selected. Correlation (Spearman coefficient) and concordance (kappa) between NYHA classification and CPET-based classifications were analyzed. A p < 0.05 was accepted as significant. Results In total, 244 patients were included. Mean age was 56 ± 14 years, and mean EF was 35.5% ± 10%. Distribution of patients according to NYHA classification was 31.2%% class I, 48.3% class II, 19.2% class III, and 1.3% class IV. Correlation (r) between NYHA and Weber classes was 0.489 (p < 0.001), and concordance was 0.231 (p < 0.001). Correlation (r) between NYHA and ventilatory classes (minute ventilation/carbon dioxide production [VE/VCO2] slope) was 0.218 (p < 0.001), and concordance was 0.002 (p = 0.959). Spearman correlation between NYHA and CPET score classes was 0.223 (p = 0.004), and kappa concordance was 0.027 (p = 0.606). Conclusion There was a moderate association between NYHA and Weber classes, although concordance was low. Ventilatory (VE/VCO2slope) and CPET score classes had a weak association and a low concordance with NYHA classes.

ABSTRACT Purpose: To analyze the association between obesity and urinary incontinence rate in men submitted to robot-assisted radical prostatectomy (RARP) in a high-volume cancer center. Materials and Methods: We reported 1.077 men who underwent RARP as the primary treatment for localized prostate cancer from 2013 to 2017. Patients were classified as non-obese (normal BMI or overweight) or obese men (BMI ≥30kg/m2). They were grouped according to the age, PSA level, D’Amico risk group, Gleason score, ASA classification, pathological stage, prostate volume, salvage/adjuvant radiotherapy, perioperative complications, and follow-up time. Urinary continence was defined as the use of no pads. For the analysis of long-term urinary continence recovery, we conducted a 1:1 propensity-score matching to control confounders. Results: Among the obese patients, mean BMI was 32.8kg/m2, ranging 30 - 45.7kg/m2. Only 2% was morbidly obese. Obese presented more comorbidities and larger prostates. Median follow-up time was 15 months for the obese. Complications classified as Clavien ≥3 were reported in 5.6% of the obese and in 4.4% of the non-obese men (p=0.423). Median time for continence recovery was 4 months in both groups. In this analysis, HR was 0.989 for urinary continence recovery in obese (95%CI=0.789 - 1.240; p=0.927). Conclusions: Obese can safely undergo RARP with similar continence outcomes comparing to the non-obese men when performed by surgeons with a standardized operative technique. Future studies should perform a subgroup analysis regarding the association of obesity with other comorbidities, intending to optimize patient counseling.

BACKGROUND Leishmania parasites cause leishmaniasis that range from self-limiting cutaneous lesions to more serious forms of the disease. The search for potential drug targets focusing on biochemical and metabolic pathways revealed the sterol biosynthesis inhibitors (SBIs) as a promising approach. In this class of inhibitors is found ketoconazole, a classical inhibitor of 14α-methysterol 14-demethylase. OBJECTIVE The present study aimed to better understand the biological response of Leishmania (Leishmania) amazonensis promastigotes at the cellular level after ketoconazole treatment. METHODS Herein, techniques, such as fluorimetry, flow cytometry, fluorescence microscopy, electron and scanning microscopy were used to investigate the cellular structures and to identify organelles affected by ketoconazole treatment. FINDINGS The study demonstrated, for the first time, the effect of ketoconazole on mitochondrion functioning and its probable relationship to cell cycle and death on L. (L.) amazonensis promastigotes (IFLA/BR/67/PH8 strain). MAIN CONCLUSIONS Ketoconazole-induced mitochondrial damages led to hyperpolarisation of this single organelle and autophagic vacuoles formation, as a parasite survival strategy. These damages did not reflect directly on the parasite cell cycle, but drove the parasites to death, making them susceptible to ketoconazole treatment in in vitro models.

Abstract We evaluated the accuracy of radiomorphometric indices (RI) and fractal dimension (FD) for screening bone mineral density (BMD) in postmenopausal patients who had breast cancer and were using aromatase inhibitors (AI). The sample consisted of 40 participants. Digital panoramic radiography (DPR) and cone beam computed tomography (CBCT) were evaluated along with dual-energy X-ray absorptiometry (DXA), which is the gold standard for detecting low BMD. According to the T-scores of DXA, the subjects were assigned into two groups: with normal BMD and with low BMD (osteopenia and osteoporosis). The area under the curve (AUC), sensitivity, and specificity with their respective confidence intervals were determined for DPR and CBCT. For DPR indices, AUC ranged from 52.6 to 75.8%. The mandibular cortical width (MCW) had the highest AUC. For FD, the total trabecular index had the highest sensitivity, while the index anterior to the mental foramen (MF) had the highest specificity. In CBCT, the AUC ranged from 51.8 to 62.0%. The indices with the highest AUC were the molar (M) and anterior (A). The symphysis (S) index had the highest sensitivity and the posterior (P) index had the highest specificity. Sensitivity and specificity were adequate for the computed tomography index (Inferior; CTI [I]). Therefore, MCW, FD of the mandible angle, and total trabecular ROI in DPR and the CTI (I), M, P, and A indices in CBCT proved to be promising tools in distinguishing individuals with low BMD. Cutoff point for these indices could be a useful tool to investigate low BMD in postmenopausal women taking AI.

Resumo Fundamento: O teste do degrau de seis minutos (TD6) é uma forma simples de avaliar a capacidade funcional, embora tenha sido pouco estudado em pacientes com doença arterial coronariana (DAC) ou insuficiência cardíaca (IC). Objetivo: Analisar a associação entre o TD6 e o consumo de oxigênio de pico (VO2pico) e desenvolver uma equação que estime o VO2pico com base no TD6, bem como determinar um ponto de corte para o TD6 que preveja um VO2pico ≥ 20 mL.kg-1.min-1 Métodos: Nos 171 pacientes submetidos ao TD6 e a um teste de exercício cardiopulmonar, análises da curva ROC, de regressão e de correlação foram usadas, e um p < 0,05 foi admitido como significativo. Resultados: A idade média foi 60±14 anos, e 74% eram do sexo masculino. A média da fração de ejeção ventricular esquerda foi 57±16%; 74% apresentavam DAC, e 28%, IC. A média do VO2pico foi 19±6 mL.kg-1.min-1, e o desempenho médio do TD6 foi 87±45 passos. A associação entre o TD6 e o VO2pico foi r 0,69 (p < 0,001). Os modelos VO2pico = 19,6 + (0,075 x TD6) – (0,10 x idade) para homens e VO2pico = 19,6 + (0,075 x TD6) – (0,10 x idade) – 2 para mulheres poderiam prever o VO2pico com base nos resultados do TD6 (R ajustado 0,72; R2 ajustado 0,53). O ponto de corte mais acurado para que o TD6 preveja um VO2pico ≥ 20 mL.kg-1.min-1 foi de > 105 passos [área sob a curva 0,85; intervalo de confiança de 95% 0,79 - 0,90; p < 0,001]. Conclusão: Uma equação que preveja o VO2pico com base nos resultados do TD6 foi derivada, e foi encontrada uma associação significativa entre o TD6 e o VO2pico. O ponto de corte do TD6, que prevê um VO2pico ≥ 20 mL.kg-1.min-1, foi > 105 passos. (Arq Bras Cardiol. 2021; 116(5):889-895)

Abstract Background: Six-minute step test (6MST) is a simple way to evaluate functional capacity, although it has not been well studied in patients with coronary artery disease (CAD) or heart failure (HF). Objective: Analyze the association between the 6MST and peak oxygen uptake (VO2peak) and develop an equation for estimating VO2peak based on the 6MST, as well as to determine a cutoff point for the 6MST that predicts a VO2peak ≥20 mL.Kg-1.min-1 Methods: In 171 patients who underwent the 6MST and a cardiopulmonary exercise test, correlation, regression, and ROC analysis were used and a p < 0.05 was admitted as significant. Results: mean age was 60±14 years and 74% were male. Mean left ventricle ejection fraction was 57±16%, 74% had CAD and 28% had HF. Mean VO2peak was 19±6 mL.Kg-1.min-1 and mean 6MST performance was 87±45 steps. Association between 6MST and VO2peak was r 0.69 (p <0.001). The model VO2peak =19.6 + (0.075 x 6MST) – (0.10 x age) for men and VO2peak =19.6 + (0.075 x 6MST) – (0.10 x age) – 2 for women could predict VO2peak based on 6MST results (adjusted R 0.72; adjusted R2 0.53). The most accurate cutoff point for 6MST to predict a VO2peak ≥20 mL.Kg-1.min-1 was >105 steps (AUC 0.85; 95% CI 0.79 -0.90; p <0.001). Conclusion: An equation for predicting VO2peak based on 6MST results was derived, and a significant association was found between 6MST and VO2peak. The cutoff point for 6MST, which predicts a VO2peak ≥20 mL.Kg-1.min-1, was >105 steps. (Arq Bras Cardiol. 2021; 116(5):889-895)

ABSTRACT Purpose: Incidence and mortality of prostate cancer (PCa) are still increasing in developing countries. Limited access to the health system or more aggressive disease are potential reasons for this. Ethnic and social differences in developed countries seem to make inappropriate to extrapolate data from other centers. We aim to report the epidemiological profile of a PSA-screened population from a cancer center in Brazil. Materials and Methods: We retrospectively selected 9.692 men enrolled in a PCa prevention program, comprising total PSA level and digital rectal examination at the first appointment, associated with complementary tests when necessary. Men aged over 40 years-old were included after shared decision-making process. Prostate biopsy (TRUS) was performed when clinically suspected for PCa. After the diagnosis, patients underwent appropriate treatment. Results: TRUS was performed in 5.5% of men and PCa incidence was 2.6%. Overall ratio between number of patients who needed to be screened in order to diagnose one cancer was 38.9 patients, with 2.1 biopsies performed to diagnose a cancer. Positive predictive value (PPV) of TRUS biopsy in this strategy was 47.2%, varying from 38.5% (<50 years-old) to 60% (>80 years-old). We evidenced 70 patients (27.9%) classified as low risk tumors, 74 (29.5%) as intermediate risk, and 107 (42.6%) as high-risk disease. Conclusions: PSA-screening remains controversial in literature. In front of a huge miscegenated people and considering the big proportion of high-risk PCa, even in young men diagnosed with the disease, it is imperative to inform patients and health providers about these data particularities in Brazil.

ABSTRACT BACKGROUND: Postpoliomyelitis syndrome is a clinical condition that can affect poliomyelitis survivors. OBJECTIVE: Our aim was to evaluate knowledge of poliomyelitis and postpoliomyelitis syndrome among Brazilian healthcare professionals. DESIGN AND SETTING: Cross-sectional study conducted at a Brazilian public higher education institution located in the state of Goiás. METHODS: The participants (n = 578) were Brazilian physicians, physical therapists, nurses, nutritionists and psychologists. A self-administered questionnaire (30 questions) was designed to probe knowledge about poliomyelitis and postpoliomyelitis syndrome. From the questionnaire, we created a structured test to objectively evaluate the knowledge of these professionals. The test was composed of 20 questions and was scored over a range from 0 (totally ill-informed) to 20 (totally well-informed). RESULTS: In general, the physicians, physical therapists and nurses demonstrated better understanding of poliomyelitis and postpoliomyelitis syndrome. The healthcare professionals who had received previous information about poliomyelitis and postpoliomyelitis syndrome had significantly higher scores than those who had never received information (P < 0.001). On average, this difference was approximately 28.6%. CONCLUSIONS: The findings from the present study indicate that there is a critical need for improvement of knowledge about postpoliomyelitis syndrome among Brazilian healthcare professionals. The services provided by these professionals may therefore become compromised. Furthermore, public healthcare initiatives should be implemented to improve knowledge among healthcare professionals.
