Resumen Cuando un choque automotriz ocurre, la energía de impacto se transfiere a los pasajeros lo cual provoca lesiones graves y decesos. Con el objeto de analizar el efecto de las cargas dinámicas en el cuerpo humano, el uso de maniquíes de impacto está en incremento. Sin embargo, su costo es demasiado alto, así como su accesibilidad. Por lo tanto, el presente artículo propone el diseño y desarrollo de un modelo discreto que representa la cabeza y cuello de un maniquí para pruebas de impacto utilizando el software de elemento finito Abaqus. El modelo está conformado por cabeza, región cervical (cuello) incluyendo discos cervicales y discos intervertebrales. La evaluación del conjunto cabeza-cuello se llevó a cabo a través de una prueba de péndulo. Durante la evaluación de parámetros tales como la aceleración, la fuerza de velocidad y posición angular de la cabeza fueron obtenidos. Finalmente, los resultados de la viabilidad del modelo fueron validados mediante el fenómeno de latigazo.

Abstract When car crashes occur, the impact energy is transferred to passengers, provoking fatalities, and severe injuries. In this sense, the use of dummies to analyze the effect of dynamic loads on the human body is increasing. However, its cost is generally expensive and difficult to acquire. Thus, the current article proposes designing and developing a head-neck dummy using Abaqus finite element method software. The design of the dummy model is formed by the head, and neck which are formed by cervical and intervertebral plates. The assessment of the new head-neck model was carried out by a pendulum test. During the evaluation of parameters such as acceleration, velocity force, and angular position of the head were obtained. Finally, the results of the viability of the model were validated through the whiplash phenomenon.

Abstract Thus, the objective of this work was to evaluate the performance of industrial drying and the quality of soybean grains using a direct-fire furnace automatically fed by wood chips. To represent the grains before drying, four samples were collected together with the sampling of the loads in the trucks carried out to classify the product in the storage unit. At drying, performance evaluations and specific energy consumption were carried out. The grains were evaluated for moisture content, germination, electrical conductivity, apparent specific mass, color, acidity index, and PAHs. Drying showed an average efficiency of 75.50%. The average chip consumption was 0.4403 kg of chip/kg of evaporated water. The specific energy consumption was 8,099.50 kJ/kg of evaporated water. The grains showed differences after drying in the characteristics of germination, electrical conductivity, and chroma. Six PAHs were detected in the samples before drying: (B(a)A, Chr, 5 MC, B(j)F, Dib(ai)P, and IcdP). After drying, in addition to the PAHs obtained before drying, five more were detected (B(b)F, B(k)F, B(a)P, Dib(al)P, and Dib(ah)A). Mean PAH concentrations were higher than the maximum values allowed by European Union legislation.

Abstract Objective The use of a fiber glass post (FGP) type and choice of FGP diameter to restore endodontically treated incisors without ferrule is controversial. This study evaluated survival rate and failure mode of severely compromised central incisors without ferrule rehabilitated using resin-based composite (RBC) with or without FGP with different diameters. Methodology A total of 60 decoronated bovine incisors without a ferrule were endodontically treated and prepared for 1.4, 1.6, and 1.8 mm diameter FGPs (Whitepost System DC 0.5, Fit 0.4, and DCE 0.5; FGM). Half of the teeth received FGPs cemented using dual-cure resin cement (Allcem Core; FGM), the other half were filled using only bulk-fill RBC (OPUS Bulk Fill; FGM). The crowns were directly restored with RBC. The roots were embedded in polystyrene resin and the periodontal ligament was simulated with polyether impression material. Fatigue testing was conducted under 5 Hz cyclic loading at 30 degrees to the incisal edge, beginning at 50 N (5,000 cycles) as a warmup. After, the load was increased 100 N every 15,000 cycles until fracture occurred. All specimens were subjected to transillumination, micro-CT analysis, and digital radiography before and after fatigue testing. Fracture mode was classified according to severity and repair potential. Data were analyzed with Kaplan-Meier survival test and post hoc log-rank test (α=0.05) for pairwise comparisons. Results Using FGP significantly increased the number of cycles to failure, irrespective of FGP diameters (p=0.001). The FGP diameters had no statistically significant effect on cycles to failure or failure mode. Conclusion Using FGP without ferrule improved survival rate of structurally severely compromised central incisors compared with rehabilitation without FGP. The diameter of the FGPs had no effect on the survival rate and failure mode.

ABSTRACT: The aim of this research was to investigate the radiographic, clinical, and histological features of cases of ameloblastoma from a period of 17 years in a Brazilian center and to explore potential differences in children and adolescen ts in relation to adults. Seventy-five patients diagnosed with ameloblastoma from 2001 to 2018 were included. Data from each patient including gender, age, histologic type, location, and radiographic characteristics were reviewed and analyzed retrospectively. The association between the clinical, radiographic, and histologic findings was investigated. No differences regarding the histological pattern of the lesions were observed between groups. Children and adolescents presented well- defined lesions associated with an unerupted tooth compared to adults (p<0.05). The presence of an unerupted tooth was associated with cortical erosion and expansion and MC displacement (p<0.05). Despite similar histologic characteristics, differential radiographic appearance was observed between young patients and adults.

RESUMEN: El objetivo de este trabajo fue investigar las características radiográficas, clínicas e histológicas de casos de ameloblastoma en un período de 17 años, en un centro brasileño y explorar las posibles diferencias en niños y adolescentes en relación con los adultos. Se incluyeron 75 pacientes diagnosticados con ameloblastoma desde 2001 hasta 2018. Los datos de cada paciente, incluyendo el sexo, la edad, el tipo histológico, la ubicación y las características radiográficas, se revisaron y analizaron retrospectivamente. Se investigó la asociación entre los hallazgos clínicos, radiográficos e histológicos. No se observaron diferencias en cuanto al patrón histológico de las lesiones entre los grupos. Los niños y adolescentes presentaron lesiones bien definidas asociadas a un diente no erupcionado en comparación con los adultos (p<0,05). La presencia de un diente no erupcionado se asoció con erosión y expansión cortical y desplazamiento de MC (p<0,05). A pesar de las características histológicas similares, se observó una apariencia radiográfica diferente entre pacientes jóvenes y adultos.

BACKGROUND Zika virus (ZIKV) is an emerging arbovirus associated with foetal malformations and neurological complications. The infection is usually associated with mild symptoms. The comparison between the allelic frequency of polymorphic genes in symptomatic infected individuals in the population can clarify the pathogenic mechanisms of ZIKV. During ZIKV infection, cytokines are produced and natural killer (NK) cells are recruited, whose activation depends on signaling pathways activated by specific receptors, such as killer cell immunoglobulin-like receptors (KIR). These molecules interact with human leukocyte antigen (HLA) class I ligands and are encoded by polymorphic genes. OBJECTIVES This study aimed to evaluate the frequency of allelic variants of the genes encoding the KIR receptors and their HLA class I ligands in 139 symptomatic ZIKV-patients and 170 controls negative for the virus, and to evaluate the role of these variants for ZIKV susceptibility. METHODS KIR and HLA class I genes were genotyped using the polymerase chain reaction-sequence specific oligonucleotide (PCR-SSO) technique. FINDINGS No significant differences in the frequency distribution of KIRs and KIR-HLA in patients compared to controls were observed. MAIN CONCLUSIONS KIR and its HLA ligands might play a minor role in ZIKV infection in the south and southeast Brazilian individuals.

Abstract The objective of this study was to evaluate the drying system using a dryer with furnace automatically fed with eucalyptus chips and another dryer manually fed with eucalyptus firewood, as well as assessing the quality of corn grains. Harvest was mechanically performed and the grains were transported by trucks to the storage unit for drying. Corn grain drying was conducted in mixed-flow dryers with a nominal capacity of 100 tons per hour. For air heating, two direct-fired furnaces were used, one automatically fed with eucalyptus chips and the other manually fed with firewood. Corn grains were evaluated for moisture content, apparent specific mass, thousand-grain weight, polycyclic aromatic hydrocarbons (PAHs), electrical conductivity and color. Drying corn grains with direct fire using firewood or chips as fuel causes contamination by PAHs. In general, the use of firewood or chips did not influence the quality of thousand-grain weight, apparent specific mass and color, while the use of chips increased electrical conductivity. It is essential that research advances in this subject, prioritizing the contamination of food, with proven carcinogenic activity, which should be treated as a high risk to public health.

RESUMO Objetivo: Analisar se a avaliação dinâmica de volumes de tomografia computadorizada de feixe cônico (TCFC) influencia a percepção de ortodontistas quanto à determinação da posição e do prognóstico de mini-implantes (MIs) inter-radiculares. Material e Métodos: Foram selecionados 30 volumes de TCFC, nos quais foram simuladas três formas de instalação de MIs: 1) MI a 1 mm de distância da lâmina dura (LD); 2) MI tocando a LD; e 3) MI sobreposto à LD. As imagens foram examinadas por 35 ortodontistas na forma de reconstruções panorâmicas, reconstruções sagitais e uma sequência de reconstruções axiais. Os examinadores avaliaram a relação entre o MI e a LD, e indicaram o prognóstico dos MIs instalados, usando uma escala de 4 pontos (quanto maior o escore, mais favorável o prognóstico). Os dados foram submetidos à análise estatística, por meio dos testes de Kappa, Friedman e Nemenyi. Resultados: Houve associação significativa entre o prognóstico, os tipos de imagem e as três formas de inserção dos MIs (p<0,05). A visualização dinâmica dos volumes de TCFC (reconstruções axiais) foi associada a maiores escores para o prognóstico e a avaliações mais confiáveis da posição dos MIs. Escores mais inconsistentes e discordantes foram mais associados às reconstruções panorâmicas e sagitais. Conclusão: A análise do volume tomográfico em reconstruções axiais pode melhorar a avaliação do ortodontista quanto à posição dos MIs inter-radiculares, apresentando impacto significativo na determinação do prognóstico do caso.

ABSTRACT Objective: To investigate the influence of dynamic visualization of cone beam computed tomography (CBCT) scans on orthodontist’s assessment of positioning status and prognosis of interradicular mini-implants (MI). Methods: Three MI positions were virtually simulated in thirty CBCT volumes: (1) MI 1 mm from the lamina dura (LD), (2) MI touching the LD and (3) MI overlapping the LD. Each position was exposed to orthodontists (n = 35) as panoramic reconstruction, sagittal reconstruction and a sequence of axial slices. Each orthodontist evaluated the MI position (relationship with the LD) and scored the prognosis using a four-point scale (the higher the score, the better the prognosis). Kappa, Friedman and Nemenyi statistics were used. Results: Statistically significant associations were detected between the prognosis scores and the type of image visualized (p<0.05). The dynamic visualization of the CBCT volume (axial slices) was associated with higher scores for prognosis and more reliable evaluation of MI positioning. Inconsistent outcomes were more frequently associated with panoramic and sagittal reconstructions. Conclusion: The dynamic visualization of axial slices allowed orthodontists to perform better assessment of MI position and considerably affected prognosis judgment.

Resumo Fundamento: Interrupções no tempo despendido em comportamento sedentário (breaks) têm sido associadas a melhores níveis de indicadores cardiometabólicos na população adulta. No entanto, em adolescentes, os achados sobre essa associação ainda são conflitantes. Objetivos: Analisar a associação do número de breaks por dia em comportamento sedentário com marcadores cardiometabólicos e avaliar se ela é moderada pelo estado nutricional e o tempo excessivo em comportamento sedentário em adolescentes. Métodos: Estudo transversal com 537 adolescentes (52,3% do sexo feminino), de 10 a 14 anos de idade, de escolas públicas de João Pessoa (PB). O número diário de breaks em comportamento sedentário (>100 counts/minutos) foi mensurado por meio de acelerômetros (Actigraph GT3X+). Os marcadores cardiometabólicos analisados foram: pressão arterial sistólica e diastólica (mmHg), glicose de jejum, colesterol total, triglicerídeos, HDL-c, LDL-c (todos em mg/dL) e índice de massa corporal (IMC) (kg/m2). Utilizou-se a regressão linear para analisar a associação do número de breaks com marcadores cardiometabólicos e avaliar se ela é moderada pelo estado nutricional e o tempo excessivo em comportamento sedentário. O nível de significância de p<0,05 foi adotado para todas as análises. Resultados: O número de breaks por dia se associou negativamente ao IMC (ß = −0,069; IC95%: −0,102; −0,035), mas não aos demais marcadores cardiometabólicos, e essa associação não foi moderada pelo estado nutricional dos adolescentes (p=0,221) e nem pelo tempo excessivo em comportamento sedentário (p=0,176). Conclusão: A inclusão de breaks no tempo em comportamento sedentário parece contribuir para valores mais baixos do IMC em adolescentes.

Abstract Background: The interruption of the time spent in sedentary behavior (breaks) has been associated with better levels of cardiometabolic indicators in the adult population, but in adolescents, further investigations are still needed to confirm these findings. Objectives: To analyze the association of the number of breaks per day in sedentary behaviors with cardiometabolic markers and whether it was moderated by nutritional status and excessive time on sedentary behavior in adolescents. Methods: This is a cross-sectional study of 537 adolescents (52.3% girls), aged between 10 and 14 years, enrolled in public schools in the city of João Pessoa, Paraíba state, Brazil. The number of daily breaks (>100 counts/minutes) in sedentary time was measured by Actigraph GT3X+ accelerometers. The following cardiometabolic markers were analyzed: systolic and diastolic blood pressure (mmHg), fasting blood glucose levels, total cholesterol, triglycerides, HDL-c, LDL-c (all in mg/dL) and body mass index (BMI) (kg/m2). Linear regression was used to analyze the association between the number of breaks and cardiometabolic markers and whether this association was moderated by nutritional status and excessive time in sedentary behavior. The significance level of p<0.05 was adopted for all analyses. Results: The number of daily breaks was negatively associated with BMI (boys – ß = −0.083; 95%CI: −0.132; −0.034 and girls – ß = −0.115; 95%CI: −0.169; −0.061), but not with the remaining cardiometabolic markers. The number of breaks per day was negatively associated with BMI (ß = −0.069; 95% CI: −0.102; −0.035), but not with the other cardiometabolic markers and this association was not moderated by the adolescents' nutritional status (p=0.221), or by excessive time in sedentary behavior (p=0.176). Conclusions: Including breaks in sedentary time seems to contribute to lower BMI values in adolescents.

Abstract In the design of multi-outlet irrigation systems, it is necessary to calculate the frictional energy losses in pipes and determine the most economical and optimal diameter, for this, there are the equations of Manning, Hanzen & Williams and Darcy & Wesbach. According to the above, the objective of this work was to perform a mathematical physical analysis of the equations of energy losses due to friction in pipes and fittings to generate at least one deterministic equation based on the Manning and Darcy & Wesbach equation for the hydraulic design of multi-outlet irrigation and reduce high costs in the operation of agricultural irrigation equipment. The study was conducted in spring 2021, at the National Technological Institute of Mexico, Technological Institute of Torreón campus. The equations of localized and frictional energy losses (Darcy & Wesbach and Manning) were algebraically merged, and three deterministic equations were obtained for the design of multiple outlets with a relative error range from -0.009 to 0.209% in relation to the equation proposed by SARH 1979 (CENAMAR).

Resumen En el diseño de sistemas de riego de multisalidas es necesario calcular las pérdidas de energía por fricción en tuberías y determinar el diámetro más económico y óptimo, para ello existen las ecuaciones de Manning, Hanzen & Williams y Darcy & Wesbach. De acuerdo con lo anterior el objetivo de este trabajo fue realizar un análisis físico matemático a las ecuaciones de pérdidas de energía por rozamiento en tuberías y accesorios para generar al menos una ecuación determinística basada en la ecuación de Manning y Darcy & Wesbach para el diseño hidráulico del riego por multisalidas y reducir altos costos en la operación de los equipos de riego agrícola. El estudio se llevó a cabo en primavera de 2021, en el Tecnológico Nacional de México, Campus Instituto Tecnológico de Torreón. Se fusionaron algebraicamente las ecuaciones de pérdidas de energía localizada y por rozamiento (Darcy & Wesbach y Manning) y se obtuvieron tres ecuaciones determinísticas para el diseño de salidas múltiples con un rango de error relativo de -0.009 a 0.209% con relación a la ecuación propuesta por la SARH 1979 (CENAMAR).

RESUMO - RACIONAL: A obesidade é caracterizada pelo acúmulo excessivo de gordura corporal prejudicial à saúde e nos últimos anos tem crescido significativamente na maioria dos países. A cirurgia bariátrica deverá ser recomendada para pacientes obesos que não obtiveram êxito no tratamento clínico e após análise da equipe multiprofissional. Objetivo: comparar os resultados metabólicos, perda ponderal e parâmetros associados à obesidade no pré e pós-operatório dos pacientes submetidos à cirurgia bariátrica. Métodos: estudo retrospectivo, descritivo, transversal, de abordagem quantitativa através da consulta a prontuários. Os dados foram coletados no período de maio a setembro de 2020, de indivíduos submetidos à cirurgia bariátrica no período de 15 anos (2003 a 2018). Foi realizada análise estatística comparativa e descritiva das variáveis antropométricas, metabólicas, bioquímicas e morbidades associadas. Resultados: a maioria era do sexo feminino (68,50%). Em ambos os sexos a maior prevalência se encontravam na faixa etária de 30 a 39 anos e mais da metade tinha obesidade grau III. A técnica cirúrgica utilizada foi o gastroplastia em Y de Roux. Após 4 meses houve uma redução significativa do perfil lipídico, dos parâmetros antropométricos e enzimas hepáticas em ambos os sexos, os quais permaneceram em declínio no final do primeiro ano, com melhora acentuada da síndrome metabólica. Conclusões: O impacto positivo determinado pela gastroplastia na perda de peso, na redução do IMC e perfil lipídico é bastante relevante já após quatro meses, e se mantém após um ano da realização do procedimento, demonstrando benefícios na redução dos fatores de risco da síndrome metabólica.

ABSTRACT - BACKGROUND: Obesity is a disease characterized by an excessive accumulation of body fat, which is harmful to health, and it has grown significantly in the past years in the majority of countries. The surgery should be recommended to those patients with obesity who did not succeed in conservative clinical therapy after a rigorous analysis by a multidisciplinary team. Objective: The aim of this study was to compare metabolic results, weight loss, and parameters associated with obesity in the preoperative and postoperative periods of patients treated with bariatric surgery. Methods: This was a retrospective, descriptive, cross-sectional, and quantitative study through consultation medical records. Data were collected from May to September 2020 from individuals treated with bariatric surgery in a period of 15 years (from 2003 to 2018). A comparative and descriptive statistical analysis of anthropometric, metabolic, biochemical, and associated morbidities was performed. Results: The majority of patients were female (68.50%). In both sexes, the highest prevalence was found in the age group of 30-39 years and more than half had grade III obesity. The surgical technique used was gastroplasty with Roux-en-Y gastric bypass. After 4 months, there was a significant reduction in the lipid profile, anthropometric parameters, and liver enzymes in both sexes, which remained decreasing till the end of the first year, with marked improvement in the metabolic syndrome (MS). Conclusions: The positive impact resulted from gastroplasty in terms of weight loss, reduction of body mass index, and lipid profile is quite relevant after 4 months and it is maintained until 1 year after the procedure, showing benefits in reducing the risk factors of the MS.

Abstract Coronavirus disease 2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus type 2 (SARS-CoV-2), is the largest pandemic in modern history with very high infection rates and considerable mortality. The disease, which emerged in China’s Wuhan province, had its first reported case on December 29, 2019, and spread rapidly worldwide. On March 11, 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic and global health emergency. Since the outbreak, efforts to develop COVID-19 vaccines, engineer new drugs, and evaluate existing ones for drug repurposing have been intensively undertaken to find ways to control this pandemic. COVID-19 therapeutic strategies aim to impair molecular pathways involved in the virus entrance and replication or interfere in the patients’ overreaction and immunopathology. Moreover, nanotechnology could be an approach to boost the activity of new drugs. Several COVID-19 vaccine candidates have received emergency-use or full authorization in one or more countries, and others are being developed and tested. This review assesses the different strategies currently proposed to control COVID-19 and the issues or limitations imposed on some approaches by the human and viral genetic variability.

Resumo Objetivo: Caracterizar as pesquisas etnográficas na área de enfermagem obstétrica quanto a seus aspectos teóricos, metodológicos e analíticos. Método: Revisão integrativa realizada nas bases de dados MEDLINE®, LILACS, BDENF e CINAHL, bem como na biblioteca virtual SciELO. Resultados: Após processo de triagem e leitura na íntegra das referências primárias, 30 artigos formaram o corpus analítico. Os métodos mais utilizados foram etnoenfermagem, etnografia e etnografia institucional; o tempo de imersão no campo variou entre 12 visitas e 48 meses, ocorrendo em contextos institucionais. As principais técnicas de coleta de dados foram observação, entrevistas individuais e guias capacitadores da etnoenfermagem. Os dados foram organizados sob a forma de temas e subtemas, analisados por meio do guia de análise da etnoenfermagem, tendo como referencial teórico a Teoria da Diversidade e Universalidade do Cuidado Cultural. Conclusão: Estudos etnográficos na área de enfermagem obstétrica situam-se no âmbito das microetnografias e são operacionalizados com aporte em referenciais teórico-metodológicos da enfermagem, sendo úteis para se analisar a complexidade dos fenômenos que envolvem o cuidado de enfermagem obstétrico, com foco nas perspectivas etic (profissionais) e emic (mulheres).

Abstract Objective: To characterize ethnographic research in the area of obstetric nursing regarding its theoretical, methodological and analytical aspects. Method: An integrative review performed in the MEDLINE®, LILACS, BDENF and CINAHL databases, as well as the SciELO virtual library. Results: Thirty (30) articles formed the analytical corpus after screening and reading the primary references in full. The most used methods were ethno-nursing, ethnography and institutional ethnography; the immersion time in the field ranged from 12 visits to 48 months occurring in institutional contexts. The main data collection techniques were observation, individual interviews and training guides for ethno-nursing. The data were organized as themes and subthemes, analyzed through the ethno-nursing analysis guide, implementing the Theory of Diversity and Universality of Cultural Care as theoretical reference. Conclusion: Ethnographic studies in the area of obstetric nursing are within the scope of microethnographies and are operationalized based on theoretical-methodological nursing references, being useful to analyze the complexity of phenomena involving obstetric nursing care, and focusing on the etic (professional) and emic (women) perspectives.

ABSTRACT The objective with this study was to evaluate the libido and sexual behavior of Pantaneiro stallions in Brazil in two periods, the rainy and dry seasons. Their sexual behavior was evaluated during mating with mares in estrus, and the libido was scored for statistical analysis. The reaction time and time to mount and ejaculate were 78.1±64.6 s and 289.0 s, respectively. The most relevant events of sexual behavior observed in the Pantaneiro stallions were mounting without erection, mounting without ejaculation, smelling, and vocalizing. In general, the season did not affect the libido of stallions. Even with the high temperatures and humidity, which could cause thermal stress, the stallions showed good libido score during most of evaluations, with some individual differences. Pantaneiro stallions are able to breed mares during the entire year and could facilitate the breeding management to raise the number of Pantaneiro horses of the herds and optimize the use of the stallions during the breeding season, with more females per male.

RESUMO O feijão-caupi possui grande importância socioeconômica, principalmente nas regiões Norte/Nordeste do Brasil. Devido a este fator o melhoramento genético dessa espécie vem se tornando cada vez mais relevante. O trabalho teve como objetivo avaliar a divergência genética entre genótipos de feijão-caupi do Banco Ativo de Germoplasma do Instituto Agronômico de Pernambuco (IPA), a fim de indicar os mais divergentes e produtivos como genitores de forma a enriquecer o programa de melhoramento da cultura nessa instituição. O ensaio foi conduzido na Estação experimental de Itapirema (IPA), Goiana-PE, em delineamento experimental de blocos casualizados com quatro repetições. Utilizaram-se 30 genótipos sendo duas testemunhas (Miranda IPA 207 e Paulistinha). Foram avaliados: início de floração, número de vagem/pedúnculo, número de vagem/planta, comprimento médio de vagem, peso de dez vagens, peso dos grãos de dez vagens, índice de grãos, número de grãos em dez vagens, peso de cem grãos, rendimento de grãos/hectare, porte, cor da flor, da folha, da vagem e do grão e a forma do grão. Existe divergência genética entre os genótipos de feijão-caupi avaliados. As características peso de vagem, início da floração, comprimento da vagem, peso de cem grãos e número de vagens por planta foram as que mais contribuíram para a divergência genética. Os cruzamentos indicados para viabilizar novas combinações gênicas mais favoráveis são: Pitiúba x Cabeçudo, Pitiúba x Manteiga e Pitiúba x Costela de Vaca.

ABSTRACT Cowpea has great socioeconomic importance, especially in the North and Northeast of Brazil, and its genetic improvement has become increasingly relevant. This study aimed to assess the genetic divergence among cowpea genotypes of the active germplasm bank of the Agronomic Institute of Pernambuco to indicate the most divergent and productive as parents aiming at enriching its breeding program in this institution. The experiment was carried out at the experimental station of Itapirema, Goiana, PE, in a randomized block design with four replications. Thirty genotypes were used in the study, being two of them the controls (Miranda IPA 207 and Paulistinha). The parameters flowering, number of pods per peduncle, number of pods per plant, pod length, ten pod weight, grain index, number of grains in ten pods, hundred-grain weight, grain yield per hectare, plant habit, color of flowers, leaves, pods, and grains, and grain shape were assessed. Genetic divergence was observed among the cowpea genotypes. Pod length and weight, flowering, hundred-grain weight, and the number of pods per plant were the main contributors to genetic divergence. Crosses indicated to enable new gene combinations more favorable for cowpea are Pitiúba x Cabeçudo, Pitiúba x Manteiga, and Pitiúba x Costela de Vaca.
