Abstract This paper describes the automation of a forearm prosthesis using the signal collected by a Fiber Bragg Grating (FBG) sensor. The FBG sensor is applied to one subject's forearm to measure the deformation as a result of the index and middle fingers when moved individually. It is possible to control a one joint model prosthesis allied to a compliant hand mechanism through signal analyses. Each finger movement has its features, such as its amplitude, which opens the possibility of using those to control different parts of the prosthesis, joint rotation by the middle finger, and compliant hand movement by the index finger. This paper presents results regarding prosthesis assembling, Hypertext Transfer Protocol (HTTP) communication latency between prosthesis and computer and tests with pre-acquired and processed FBG signal data. The prosthesis wrist rotation movement is related to the middle finger signal, and its compliant mechanism actuation is due to index finger signal. The communication between prosthesis and the computer had a mean latency of 140 ms and a standard deviation of 18 ms. The results demonstrate the potential for using the sensor system and automated prosthesis in other applications involving real-time forearm sensing, multi-finger signal analysis, and prosthetic movement.

Abstract Vibration analysis systems are used to assess the operational condition of machines and electromechanical components in various applications. This work presents a measurement and feature extraction system that analyzes dynamic strain patterns in signals measured by fiber Bragg grating (FBG). The features were used to identify different simulated operational conditions in an electromechanical relay. The selection of the best feature space in the first approach was performed by statistical criteria that determine the threshold values and frequency bands to calculate each signal's switching time and power spectral density (PSD). These parameters are used in the support vector machine (SVM) algorithm, which presents 98 % accuracy for distinguishing four distinct conditions. Another methodology for extracting features, called wavelet scattering transform (WST), was used to demonstrate that it is possible to achieve even better performance levels. The results allow extending the methodology to more complex systems.

Abstract In this work, measuring capabilities of a Sagnac Interferometer-based Distributed Optical Fiber Sensor (DOFS) system are demonstrated by comparing its results to a conventional amplitude-based Distributed Acoustic Sensing (DAS) system. Through a set of three different experiments, it was demonstrated that both sensing systems can detect and locate dynamical deformation along the fiber, in addition to determining its frequency components. The coherent amplitude-based DAS presented a lower background noise. In contrast, even though the Sagnac interferometry-based system presented low-frequency noise in the measurements, it is less susceptible to harmonic distortion for higher amplitude deformations since its sensing principles rely on the measurement of the accumulated phase rather than the amplitude of the backscattered signal purely. Accordingly, the Sagnac interferometry-based system arises as a promising and rather accessible topology for a DOFS implementation. work Interferometerbased Interferometer based (DOFS amplitudebased (DAS experiments fiber components contrast interferometrybased interferometry lowfrequency low measurements purely Accordingly implementation

Abstract Background Atrial fibrillation (AF) is the most common arrhythmia in patients with end-stage renal disease (ESRD). The coexistence of high thromboembolic and hemorrhagic risks, added to the lack of strong scientific evidence on the safety of anticoagulants in the setting of renal failure, makes this a clinically challenging situation. Objectives To describe the clinical-demographic profile and prevalence of AF in the population with ESRD undergoing dialysis. Secondary objectives include the assessment of thromboembolic (CHA2DS2VASC) and bleeding (HASBLED) risk scores. Methods Cross-sectional analytical-descriptive study, carried out between January and March 2020. Patients with ESRD were evaluated by means of a medical history questionnaire, physical examination, and 12-lead electrocardiogram. A chi-square (χ2) association test was applied to calculate association between clinical variables and AF, with a significance level of α = 0.05. Results This study evaluated 295 patients, most of whom were men (170), elderly (63, IQR 53-71), current smokers (130), with associated cardio-endocrine comorbidities. The prevalence of AF was 6.7% (20). Heart failure (HF) (χ2=15.417; p<0.001), age of 65 years or older (χ2=14.584; p<0.001), and anticoagulation (χ2=5.715; p<0.01) were associated with AF. The median CHA2DS2VASC and HASBLED was 4 and 3, respectively. Eight patients were taking warfarin and five were receiving apixaban. Conclusion The prevalence of AF in this study is similar to that reported in other published articles on the subject, and patients were at high risk for cardiovascular outcomes. Non-anticoagulation strategy was commonly adopted due to controversies in the literature as well as the absence of published randomized clinical trials.

ABSTRACT Objective: Evaluate the influence of isolated and associated prepregnancy obesity and gestational diabetes mellitus (GDM) on adverse perinatal outcomes. Materials and methods: Cross-sectional observational study with women who delivered at a Brazilian Maternity Hospital, between August and December 2020. Data were collected by interview with application form, and medical records. Sample was stratified by body mass index (BMI) and GDM screening in four groups: no obesity (BMI < 30 kg/m2) no GDM – reference; isolated GDM; isolated obesity (BMI ≥ 30 kg/m2); and obesity with GDM. Preeclampsia (PE), cesarean section (CS), large-for-gestational-age (LGA) newborn and admission to neonatal intensive care unit (NICU) were analyzed by odds ratio (OR) adjusted for confounding factors, adopting 95% confidence interval (CI) and P < 0.05 statistically significant. Results: From 1,618 participants, isolated obesity group (233/14.40%) had high chance of PE (OR = 2.16; CI: 1.364-3.426; P = 0.001), isolated GDM group (190/11.74%) had high chance of CS (OR = 1.736; CI: 1.136-2.652; P = 0.011) and NICU admission (OR = 2.32; CI: 1.265-4.261; P = 0.007), and obesity with GDM group (121/7.48%) had high chance of PE (OR = 1.93; CI: 1.074-3.484; P = 0.028), CS (OR = 1.925; CI: 1.124-3.298; P = 0.017) and LGA newborn (OR = 1.81; CI: 1.027-3.204; P = 0.040), compared with reference (1,074/66.38%). Conclusion: Obesity and GDM enhances the chance of different negative outcomes, worsening this prognosis when associated.

Abstract This observational, cross-sectional and quantitative study, by means of the assessment instruments Brief Pain Inventory, Functional Assessment of Chronic Illness Therapy Spiritual Well-Being and Beck Depression Inventory – Short Form, evaluated the influence of spirituality and depression in the pain perception of patients with metastatic breast cancer. Mean age was 57.3 years. Of the 30 participants, 24 (80%) were treated in a public service, 17 (57%) had been diagnosed with breast cancer for more than 5 years, and 27 (90%) were religious or spiritual. Patients with spiritual well-being scores above the median had lower depressive symptom scores (3 vs. 6; p =0.021). The median total score of spiritual well-being showed no significant difference when stratified by median pain perception (31.5% vs. 28.5%; p =0.405). Greater spiritual well-being may be related to lower rates of depression.

Resumen Este estudio observacional, transversal y cuantitativo utilizó los instrumentos Brief Pain Inventory (dolor), Functional Assessment of Chronic Illness Therapy Spiritual Well-Being (bienestar espiritual) y Beck Depression Inventory – Short Form (depresión), para evaluar si la espiritualidad y la depresión influencian en la percepción del dolor en pacientes con cáncer de mama metastásico. La edad promedio fue de 57,3 años; de las 30 participantes, 24 (80%) recibían atención pública; 17 (57%) tenían diagnóstico de cáncer de mama hace más de cinco años; y 27 (90%) solían tener alguna práctica religiosa/espiritual. Aquellas con puntuación de bienestar espiritual superior a la mediana tuvieron una puntuación más baja de síntomas depresivos (3 vs. 6; p =0,021). No hubo diferencias significativas en la mediana de la puntuación total de bienestar espiritual cuando se estratificó por la percepción mediana del dolor (31,5% vs. 28,5%; p =0,405). Una mayor sensación de bienestar espiritual se relacionó a bajas tasas de depresión.

Resumo Mediante estudo observacional, transversal e quantitativo que utilizou os instrumentos de avaliação Brief Pain Inventory (dor), Functional Assessment of Chronic Illness Therapy Spiritual Well-Being (bem-estar espiritual) e Beck Depression Inventory – Short Form (depressão), busca-se avaliar a influência da espiritualidade e da depressão na percepção de dor de pacientes acometidas por neoplasia de mama metastática. A idade média foi 57,3 anos e, das 30 participantes, 24 (80%) tratavam-se em serviço público; 17 (57%) tinham diagnóstico de câncer de mama há mais de cinco anos; e 27 (90%) realizavam alguma prática religiosa/espiritual. Pacientes com escore de bem-estar espiritual acima da mediana apresentaram menor escore dos sintomas depressivos (3 vs . 6; p =0,021). Não houve diferença significativa em relação à mediana do escore total do bem-estar espiritual quando estratificado pela mediana da percepção de dor (31,5% vs . 28,5%; p =0,405). Maior manifestação de bem-estar espiritual pode estar relacionada a menores índices de depressão.

Abstract Neurological disorders in cattle comprise a group of economically relevant diseases with high occurrence and mortality. In this way, the objective was to carry out an epidemiological study of the diseases with neurological manifestations in cattle admitted (alive or dead) to the Garanhuns Bovine Clinic/Federal Rural University of Pernambuco (CBG/UFRPE) from January 2009 to December 2019. Epidemiological information was collected from the clinical records regarding the age group, rearing system, time of year, and area of origin of the animals. The diseases were grouped into categories according to their origin: toxic or toxi-infectious, viral, traumatic/physical, parasitic, metabolic degenerative, bacterial, neoplastic, and others. A total of 6103 cattle were treated during the study period, of which 604 (10.1%) were diagnosed with diseases that had neurological manifestations. Of these, 331 cases were of single occurrence, and 231 cases occurred as outbreaks in the herd. Death was the outcome in almost 80% of the cases (465/596). The frequencies of the different categories were toxic or toxi-infectious (25.2%), viral (21.5%), traumatic/physical (13.6%), parasitic (9.8%), metabolic (9.3%), degenerative (2.3%), bacterial (2.2%), neoplastic (1.2%), and others (1.2%). It was found that almost half of the animals were older than 24 months (229/475), almost 80% were females, more than 60% were submitted to a semi-intensive to intensive rearing system, and the occurrence of disease was higher during the dry period of the year (363/614). The three most frequent neurological diseases in this study were rabies, trauma, and botulism.

Resumo Os distúrbios neurológicos em bovinos abrangem um grupo de enfermidades economicamente relevantes de elevada ocorrência e mortalidade. Desta forma, objetivou-se realizar um estudo epidemiológico das enfermidades que cursaram com manifestações neurológicas que deram entrada (vivos ou mortos) na Clínica de Bovinos de Garanhuns/Universidade Federal Rural de Pernambuco no período de janeiro de 2009 a dezembro de 2019. Nos prontuários clínicos, foram coletadas informaçõe epidemiológicas referentes ao sexo; a faixa etária; ao sistema de criação, época do ano e a área de procedência dos animais. As doenças foram agrupadas em categorias de acordo com sua origem: tóxica ou toxi-infecciosa, viral, traumática, parasitária, degenerativa, metabólica, bacteriana, neoplásica e outras. Um total de 6103 bovinos foram atendidos no período estudado, dos quais 604 (10,1 %) foram diagnosticados com enfermidades que cursaram com manifestações neurológicas. Destes, 331 casos foram de ocorrência individual, 231 casos cursaram como surtos no rebanho. Quase 80% dos casos (465/596) teve o óbito como desfecho. As frequências das distintas categoria foram tóxica ou toxi-infecciosa (25,2%), viral (21,5%), traumática/física (13,6%), parasitária (9,8%), metabólica (9,3%, degenerativa (2,3%), bacteriana (2,2%), neoplásica (1,2%), outras (1,2%). Verificou-se que quase metade dos animais apresentavam idade superior a 24 meses (229/475), quase 80% eram fêmeas, mais de 60% eram submetidos a um sistema de criação de semi-intensivo a intensivo e a ocorrência foi maior durante o período seco do ano (363/614). As três enfermidades com manifestações neurológicas de maior ocorrência neste estudo foram a raiva, os traumatismos e o botulismo.

Abstract This study aimed to identify clinical and laboratory variables that could help predict the negative outcome in cattle affected by gastrointestinal emergencies. A retrospective cohort study was carried out using multivariate logistic regression analysis based on data collected from the clinical records of cattle hospitalized at the Garanhuns Bovine Clinic, UFRPE campus. One hundred and twenty-two cattle met the inclusion criteria established for the study. Among the clinical variables, heart rate (HR) and abdominal distension are associated with the outcome in animals with right displaced abomasum (RDA), and anorexia and 10% dehydration in animals with an obstructive intestinal disorder. Among the laboratory variables, plasma fibrinogen (PF) and total leukocyte count were associated with the outcome in animals with RDA, while PF and plasma L-lactate were associated with animals with an obstructive intestinal disorder. HR and the total leukocyte count remained in the final model of the regression adjusted for animals with RDA. On the other hand, plasma L-lactate and PF remained in the final model in the adjusted model for animals with an obstructive intestinal disorder. Cattle with RDA and HR higher than 90 bpm present an increased chance of having a negative outcome whereas cattle with obstructive intestinal disorder and plasma L-lactate higher than 1.84 mmol/L or PF higher than 850 mg/dL have a higher chance of not survive. Therefore, clinical and laboratory variables such as HR, fibrinogen, and plasma L-lactate are useful to predict the negative outcome in cattle with gastrointestinal emergencies, especially RDA and obstructive intestinal disorders.

Resumo Este estudo teve como objetivo identificar variáveis clínicas e laboratoriais que pudessem ajudar a predizer o desfecho negativo em bovinos acometidos por emergências gastrointestinais. Foi realizado um estudo de coorte retrospectivo por meio de análise de regressão logística multivariada com base em dados coletados dos prontuários de bovinos internados na Clínica de Bovinos de Garanhuns, campus da UFRPE. Cento e vinte e dois bovinos atenderam aos critérios de inclusão estabelecidos para o estudo. Dentre as variáveis clínicas, a frequência cardíaca e a distensão abdominal estão associadas ao desfecho em animais com deslocamento de abomaso à direita (DAD), e anorexia e 10% de desidratação em animais com distúrbio intestinal obstrutivo. Entre as variáveis laboratoriais, o fibrinogênio plasmáticao (FP) e a contagem total de leucócitos foram associados ao desfecho em animais com DAD, enquanto o FP e o L-lactato plasmático foram associados a animais com distúrbio intestinal obstrutivo. A frequência cardíaca (FC) e a contagem total de leucócitos permaneceram no modelo final da regressão ajustada para animais com DAD. Por outro lado, o L-lactato plasmático e o FP permaneceram no modelo final ajustado para animais com distúrbio intestinal obstrutivo. Bovinos com DAD e FC maior que 90 bpm apresentam maior chance de ter um desfecho negativo, enquanto bovinos com distúrbio intestinal obstrutivo e L-lactato plasmático maior que 1,84 mmol/L ou FP maior que 850 mg/dL têm maior chance de não sobreviver. Portanto, variáveis clínicas e laboratoriais como FC, FP e L-lactato plasmático são úteis para predizer o desfecho negativo em bovinos com doenças emergências gastrointestinais, especialmente DAD e distúrbios intestinais obstrutivos.

Abstract Partial discharges can occur in different types of electric equipment and cause progressive insulation deterioration, so there is interest in monitoring partial discharges for assessing the state of the isolation of an electric system and to predict failures. Techniques to detect partial discharges, such as detecting ultrasonic emission, have been proposed in the literature, but as various effects can co-occur during a discharge, identifying characteristics in sound and pressure waveforms and correlating then with discharge characteristics is difficult. Simulations can assist in these correlations by allowing the isolation of the different phenomena. In this work the drift diffusion model, including photoionization, is coupled with the linearized compressible Navier-Stokes equations to simulate ultrasonic waves produced by partial discharges. Previous works have used the incompressible Navier-Stokes equations, so they can simulate ionic wind produced by the Trichel pulses, but no sound. In the literature, simulations have focused either on streamers or Trichel pulses. In this work both discharges and produced sound waves are successfully simulated for the needle-plane geometry in air. The electric current and charge per pulse are compared with experimental results reported in the literature for the same discharge conditions. The simulations have demonstrated that the sound waves depart from the electrode tip for the Trichel pulses, and for the streamers two sound waves are produced, one from the electrode tip and the other from the whole discharge length. Differences in the wave front with respect to the relative position to the electrode tip were analyzed, showing that near the discharge spot the sound wave is not a spherical wavefront. The sound wave for one of the discharges in the Trichel pulse regime was compared with experimental results in the literature. Results are in good agreement with the experimental data found in the literature. Both current and sound waves were successfully predicted and correlated with the discharge, results that can be used to help in the detection of partial discharges.

RESUMEN En los últimos años el cultivo de café guatemalteco ha sufrido declinación en su rendimiento como resultado de la roya del café. El uso de cultivares resistentes a esta enfermedad y con potencial para producir cafés con buena calidad de bebida es fundamental para la sustentabilidad del cultivo en el país. El objetivo de este estudio fue analizar el potencial de calidad del grano y el perfil sensorial de genotipos de café Arábica resistentes a la roya, en función de diferentes tiempos de fermentación biológica. El experimento se implementó en julio de 2014, en la finca El Panorama, ubicada en el municipio de San Rafael Pie de La Cuesta, Departamento de San Marcos, Guatemala. Se probaron ocho progenies F5 resistentes a la roya y se utilizaron como controles los cultivares Marsellesa y Bourbon Amarelo. Cada genotipo fue sometido a dos tiempos de fermentación biológica en agua, después del pelado (24 y 72 h). El diseño experimental fue bloques completos al azar con tres repeticiones en un esquema factorial 10 (genotipos) × 2 (tiempos), totalizando 60 unidades experimentales. Se evaluó la calidad, perfil sensorial y granulometría de los tratamientos. Todos los genotipos estudiados resistentes a la roya mostraron potencial para la producción de cafés especiales en Guatemala y una granulometría superior en relación al Bourbon Amarelo. Marsellesa y Bourbon Amarelo obtuvieron puntajes finales más altos y los atributos de sabor, regusto, acidez, cuerpo, equilibrio y en general, fueron más acentuados. El tiempo de fermentación biológica no influyó en la puntuación final del café (pontuación total en el protocolo SCA); sin embargo, hubo un cambio en el perfil sensorial, con énfasis en el cultivar Marsellesa, que aumentó la frecuencia de notas frutales y redujo las notas de caramelo con mayor tiempo de fermentación.

SUMMARY In recent years, the Guatemalan coffee plantations have suffered a decline in its yield as a result of coffee rust. The use of cultivars resistant to this disease and with the potential to produce coffee with good drinking quality is essential for the sustainability of coffee cultivation in the country. The aim of this study was to analyze bean quality potential and the sensory profile of rust-resistant Arabica coffee genotypes as a function of different times of biological fermentation. The experiment was carried out in July 2014, at El Panorama farm, located in the municipality of San Rafael Pie de La Cuesta, Department of San Marcos, Guatemala. Eight rust resistant F5 progenies were tested and cultivars Marsellesa and Bourbon Amarelo were used as controls. Each genotype was subjected to two times of biological fermentation in water, after peeling (24 and 72 h). The experimental design was randomized complete blocks with three replications, in a 10 (genotypes) × 2 (times) factorial scheme, totaling 60 experimental units. The quality, sensory profile and granulometry of the treatments were evaluated. All the rust-resistant genotypes studied showed potential to produce specialty coffees in Guatemala and a superior granulometry in relation to Bourbon Amarelo. Marsellesa and Bourbon Amarelo obtained higher final scores and the attributes flavor, aftertaste, acidity, body, balance and overall were more accentuated. The time of biological fermentation did not influence the final score of the coffee (total score in the SCA protocol); however, there was a change in the sensory profile, with emphasis on cultivar Marsellesa, which increased the frequency of fruity notes and reduced caramel notes with longer fermentation time.

Objetivo: analisar a Política de Garantia de Preços Mínimos para os Produtos da Sociobiodiversidade - PGPMBio com um olhar para a composição do custo de extração da Castanha-da-amazônia nos Estados de Rondônia e Acre. Materiais e Métodos: utilizou-se da abordagem qualitativa por meio de um estudo de campo. A Matriz proposta por Easton (1957) possibilitou a análise da Política Pública. A pesquisa de campo ocorreu em três momentos distintos, com 34 entrevistados: o primeiro foi em Brasiléia - AC em novembro de 2014, em Porto Velho - RO em março de 2015 e por fim em Porto Velho-RO, em Brasiléia - AC e Cobija - Bolívia em junho de 2015. Resultados: Concluiu-se que há uma discrepância entre o preço mínimo definido na PGPMBio e o preço pago pelo mercado para os casos estudados. Os resultados apontam que a PGPMBio não considera custos ambientais na elaboração do preço mínimo, empregando critérios econômicos em um contexto que exige visão sustentável. Limitações do estudo: tamanho da amostra de extrativista que, por se apresentar em uma quantidade reduzida impossibilita a expansão dos resultados para toda a população, ficando limitada à realidade dos indivíduos entrevistados. Implicações práticas: Sugere-se a inclusão de bonificações por serviços ambientais no cálculo do preço mínimo. Originalidade: o reconhecimento da força de trabalho do extrativista da Castanha-da-amazônia na composição do custo do produto. Isso foi possível devido à análise de custos de produção da Castanha-da-amazônia por meio da metodologia de análise de políticas públicas de Easton (1957) e a simultânea verificação da aplicabilidade da PGPMBio entre os extrativistas.

ABSTRACT Objective: To analyze the Minimum Price Guarantee Policy for Sociobiodiversity Products - PGPMBio with focus on the composition of the extraction cost of the Brazil nut in the states of Rondônia and Acre. Materials and Methods: This work used a qualitative approach through a field study. The Matrix proposed by Easton (1957) enabled an analysis of Public Policy. The field research took place at three different times, with 34 respondents: the first was in Brasiléia -AC) Acre State) in November 2014, in Porto Velho - RO (Rondônia State) in March 2015, in Brasiléia - AC and Cobija - Bolivia in June 2015. Results: It was concluded that there is a discrepancy between the minimum price defined in PGPMBio and the price paid by the market in the cases studied. The results show that PGPMBio does not consider environmental costs in the elaboration of the minimum price, employing economic criteria in a context that requires a sustainable vision. Study limitations: The size of the extractivist sample, which, due to its small quantity, makes it impossible to expand the results for the entire population, being limited to the reality of the interviewees. Practical implications: It is suggested to include bonuses for environmental services in the calculation of the minimum price. Originality: The recognition of the workforce on the extractivism of the Chestnut-of-the-Amazon in the composition of the product’s cost. This was possible due to the analysis of production costs of the Chestnut-of-the-Amazon through the methodology of analysis of public policies of Easton (1957) and the simultaneous verification of the applicability of PGPMBio among the extractivists.

Abstract The present work describes the use of a simulation model based on asymptotic methods (ray tracing) on the propagation of ultra-wideband radio signals in a densely-arborized urban channel. The model was previously validated and adjusted using data obtained from measurement campaigns in the millimeter-wave band in locations different from the one to be analyzed here. The simulation uses deterministic methods to predict the received power, cross-polar discrimination, root mean square delay spread, and mean delay in a channel with a high density of scatterers (trees, buildings, and poles). Simulated signals were transmitted in the vertical and horizontal polarizations, considering non-specular reflections caused by rough surfaces and the effect of the transmitter’s height variation in outdoor channels.

Abstract Objective: To evaluate cardiac function and structural changes in children of diabetic mothers in the fetal and neonatal period using Doppler-echocardiographic data. Method: A prospective, descriptive observational study conducted in a private and tertiary care service for high-risk pregnant women. It included 48 children of mothers with gestational diabetes mellitus (GDM) considered clinically compensated during pregnancy, with a single fetus and absence of malformations. Myocardial thickness, shortening fraction, left ventricular (LVMPI) and right ventricular (RVMPI) myocardial performance index, and mitral and tricuspid valve E/A ratio were evaluated in 96 echocardiographic exams with Doppler. Results: The hypertrophic cardiomyopathy was 29% vs 6% p = 0.006 in the prenatal and postnatal periods respectively. The shortening fraction was 0% vs 6% p = 0.242 in the fetuses and newborns respectively. The myocardial performance index of the right ventricle was 12% vs 54% p ≤ 0.001, and on the left ventricle 27% vs 60% p = 0.001 in the prenatal and postnatal periods respectively. The ratio of mitral valve E/A waves was 6% vs 50% p ≤ 0.001 and the ratio of tricuspid valve E/A waves was 0% vs 27% p 0.001 in the fetuses and newborns respectively. Conclusion: A decrease in the rate of myocardial hypertrophy and changes in cardiac function parameters were observed in the fetal and neonatal periods.

Resumo Objetivos: avaliar a assistência pré-natal prestada a gestantes de baixo risco usuárias do Sistema Único de Saúde da cidade de Joinville – SC. Métodos: trata-se de um estudo observacional transversal realizado de março de 2018 a fevereiro de 2019, mediante entrevista e análise do Cartão da Gestante de puérperas maiores de 18 anos, procedentes de Joinville, que realizaram o pré-natal no SUS, sendo excluídas puérperas desistentes. Avaliou-se a assistência pré-natal mediante critérios preconizados pelo Programa de Humanização no Pré-natal e Nascimento. Resultados: foram entrevistadas 683 puérperas. Os critérios com maiores índices de adequação foram acessibilidade (99,6%), início precoce do pré-natal (92,7%) e realização de 6 ou mais consultas (87,1%) e os critérios que apresentaram as menores taxas de adequação foram o conjunto de orientações (17,7%) e os exames do terceiro e primeiro trimestre (42,5% e 63,5% respectivamente). Conclusão: conclui-se que a assistência pré-natal realizada pelo SUS da cidade de Joinville, não obstante da acessibilidade praticamente universal, do início precoce e da prevalência de puérperas com mais de 6 consultas, demonstrou declínio acentuado na análise dos indicadores preconizados.

Abstract Objectives: to evaluate prenatal care provided to low-risk pregnant women users of the Sistema Único de Saúde (SUS) (Public Health System) in the city of Joinville, SC. Methods: this is a cross-sectional observational study carried out from March 2018 to February 2019, through interview and analysis of the Pregnant Card of puerperal over 18 years old, from Joinville, who underwent prenatal care at SUS, excluding recent given up puerperal. Prenatal care was evaluated according to the recommended criteria by the Prenatal and Birth Humanization Program. Results: 683 mothers were interviewed. The criteria with the highest levels of adequacy were accessibility (99.6%), early initiation on prenatal care (92.7%) and 6 or more consultations (87.1%) and the criteria with the lowest rates of adequacy were the set of guidelines (17.7%) and the third and first trimester exams (42.5% and 63.5% respectively). Conclusion: it is concluded that the prenatal care provided by SUS in the city of Joinville, despite the almost universal accessibility, the early onset and the prevalence of puerperal women with more than 6 consultations, showed a sharp decline in the analysis of the recommended indicators.
