RESUMEN

Viral gastroenteritis is commonly reported in dogs and involves a great diversity of enteric viruses. In this research, viral diversity was investigated in dogs with diarrhea in Northern Brazil using shotgun metagenomics. Furthermore, the presence of norovirus (NoV) was investigated in 282 stool/rectal swabs of young/adult dogs with or without diarrhea from two public kennels, based on one-step reverse transcription polymerase chain reaction (RT-PCR) for genogroup VI and VII (GVI and GVII) and real-time RT-PCR for GI, GII, and GIV. Thirty-one viral families were identified, including bacteriophages. Phylogenetic analyses showed twelve complete or nearly complete genomes belonging to the species of Protoparvovirus carnivoran1, Mamastrovirus 5, Aichivirus A2, Alphacoronavirus 1, and Chipapillomavirus 1. This is the first description of the intestinal virome of dogs in Northern Brazil and the first detection of canine norovirus GVII in the country. These results are important for helping to understand the viral groups that circulate in the canine population.

RESUMEN

Aim: To describe the oral finding, physical features and medical features with the genetic diagnosis of a Pentasomy X. Case report: A 6-year-old female patient was referred for oral evaluation presenting acute pain related to ulcers in the attached gingival and dorsum of tongue mucosa. Medical history revealed Pentasomy X associated with interatrial communication, convergent strabismus, recurrent seizures, dysautonomia, episodes of thrombosis and cognitive delay with limited oral communication skills. A palliative oral treatment was applied. Oral hygiene improvement and surveillance were decided considering the absence of dental hypersensitivity, post eruptive enamel breakdowns or dental caries. Less than 30 cases had been reported in the literature, reflecting the rare nature of this genetic disorder and with great difficulties to perform dental treatment. As regards the oral health status of these patients, with an emphasis on dental care, information is totally lacking. Conclusion: Oral care in patients with genetic syndromes must consider the status in general health to prevent medical complications associated with oral disease or dental treatment. Minimal intervention and surveillance are appropriate options in customized therapy.

Objetivo: Describir los hallazgos orales, características físicas y médicas con el diagnóstico genético de una pentasomía X. Reporte de caso: Paciente de 6 años remitida para evaluación bucal por presentar dolor agudo relacionado con úlceras en la encía adherida y dorso de la lengua. La historia clínica reveló pentasomía X asociada con comunicación interauricular, estrabismo convergente, convulsiones recurrentes, disautonomía, episodios de trombosis y retraso cognitivo con habilidades limitadas de comunicación oral. Se aplicó un tratamiento oral paliativo. Se decidió la mejora de la higiene oral y la vigilancia considerando la ausencia de hipersensibilidad dental, fracturas de esmalte poseruptivas o caries dental. Se han reportado menos de 30 casos en la literatura, lo que refleja la naturaleza rara de este trastorno genético y con grandes dificultades para realizar el tratamiento odontológico. En cuanto al estado de salud bucal de estos pacientes, con énfasis en el cuidado dental, la información es poca. Conclusión: El cuidado bucal en pacientes con síndromes genéticos debe considerar el estado de salud general para prevenir complicaciones médicas asociadas con enfermedades bucales o tratamientos odontológicos. La intervención mínima y la vigilancia son opciones apropiadas en la terapia personalizada.

Foi realizado tratamento odontológico necessário ao paciente, com os devidos cuidados e terapia reabilitadora com prótese parcial removível superior e inferior. Concluímos que o tratamento odontológico educacional, preventivo, restaurador e reabilitador foi satisfatório e a empatia, como processo dinâmico, envolveu mecanismos cognitivos, afetivos e comportamentais e foi reconhecida por seus efeitos positivos na promoção da saúde bucal do paciente.

This paper aims to report an individualized, inclusive, and humanized dental approach, emphasizing the importance of treating a child aged four years and three months with neurofibromatosis type 1. The patient was referred and treated at the Clinic of the Specialization Course in Pediatric Dentistry of the Graduate School, School of Dentistry, Universidad de la República, Montevideo, Uruguay. The clinical examination revealed scars from the surgical treatment of the plexiform neurofibroma and neck and oral muscle hypotonicity. The intraoral clinical examination showed large edentulous areas as 15 deciduous teeth were missing. The patient had active carious lesions, generalized microbial biofilm on the tooth surfaces, and gingival bleeding. A comprehensive treatment was provided, as well as restorative therapy with upper and lower removable partial dentures. We conclude that the dental educational, preventive, restorative, and rehabilitation treatment was satisfactory. Furthermore, empathy, as a dynamic process, involved cognitive, affective, and behavioral mechanisms. It also helped enhance the patient's oral health.

RESUMEN

Abstract: Sugarcane is an important Brazilian commodity, being usually cultivated in soils with low natural fertility. This study aimed to isolate diazotrophic endophytes from sugarcane tissues and evaluate the morphological and physiological characteristics of their colonies as well as their plant growth-promoting (PGP) traits in select diazotrophic endophytic bacteria. Fifty-six bacterial isolates were identified in the sugarcane tissues, and these isolates presented distinct morphological and physiological traits. A total of thirty-five bacterial isolates were biochemically evaluated. Overall, Bacillus was the dominant genus. Isolates of Methylobacterium spp. and Brevibacillus agri were present only in leaves, while Herbaspirillum seropedicae occurred only in stems. Except to IPA-CF45A, all isolates were nitrogenase positive. All endophytes exhibit production of indol 3-acetic acid. Over 50% of endophytes solubilize phosphate, release N-acyl homoserine lactones, and present the activity of 1-aminocyclopropane-1-carboxylic acid deaminase, catalase, lipase and protease. The network analysis showed that isolates belonged to Burkholderia, Herbaspirillum, and Methylobacterium interact with Bacillus. Bacterial endophytes exhibited distinct morphological, physiological, and PGP traits that are useful for sustainable agriculture, highlighting the isolates IPA-CC33, IPA-CF65, IPA-CC9 and IPA-CF27. Further studies on the effects of these diazotrophic endophytes and their potential for providing microbial inoculants for improving sugarcane fields will provide valuable information to maintain the sustainability and environment quality.

RESUMEN

This study aims to determine the impact of the COVID-19 pandemic, specifically considering the mandatory social isolation measures implemented, on the perceived stress of a sample of dentists and dental students from Latin America and the Caribbean, as well as the associated sociodemographic and pandemic-related variables. A cross-sectional survey was conducted with a sample of 2036 dentists and dental students (1433 women). For the main outcome, the 14-item Perceived Stress Scale (PSS-14) was used. The survey also questioned sociodemographic aspects, questions on the COVID-19 pandemic, health variables, and habits. Descriptive, bivariate, and multivariate analyses (linear regression) were applied to observe the factors associated with perceived stress. The PSS-14 mean score was 24.76 (±11.76). Hierarchical regression models showed significant variables associated with the PSS-14 scores: income level during mandatory social isolation, having older adults under care during mandatory social isolation, self-perceived level of concern regarding COVID-19, self-perceived health, Coffee consumption during mandatory social isolation. In general terms, the pandemic has influenced the personal, social, labor, and everyday life of dental staff and affected the mental health of this population specifically when perceived stress is considered. Public policies, strategies, and mental health surveillance systems are required for this population.

RESUMEN

Soil microbial communities represent the largest biodiversity on Earth, holding an important role in promoting plant growth and productivity. However, the knowledge about how soil factors modulate the bacteria community structure and distribution in tropical regions remain poorly understood, mainly in different cowpea producing ecoregions belonging to Northeastern Brazil. This study addressed the bacterial community along three different ecoregions (Mata, Sertão, and Agreste) through the16S rRNA gene sequencing. The results showed that soil factors, such as Al3+, sand, Na+, cation exchange excel, and total organic C, influenced the bacterial community and could be a predictor of the distinct performance of cowpea production. Also, the bacterial community changed between different ecoregions, and some keystone groups related to plant-growth promotion, such as Bradyrhizobium, Bacillales, Rhizobiales, and Solibacillus, were correlated to cowpea yield, so revealing that the soil microbiome has a primordial role in plant productivity. Here, we provide evidence that bacterial groups related to nutrient cycling can help us to increase cowpea efficiency and we suggest that a better microbiome knowledge can contribute to improving the agricultural performance.

RESUMEN

ABSTRACT: This study evaluated the activity of rhizobia isolates inoculated in large (18 mm) and small (11 mm) seeds on lima bean growth, nodulation and N fixation. Selected rhizobia isolates were compared with a reference strain CIAT899 and two controls without inoculation. Large seeds contributed for highest plant growth, nodulation and N fixation than small seeds. The isolates UFPI-59, UFPI-18 and UFPI-38 promoted the highest values of shoot and root dry weight, respectively. The isolates UFPI-32 promoted the highest values of nodule number, while UFPI-59 promoted the highest values of nodule dry weight. The isolates UFPI-38 and UFPI-59 promoted the highest accumulation of N. This study showed that seed size really influences lima bean growth, nodulation and BNF. Considering rhizobia isolates, UFPI-59, UFPI-38, and UFPI-18 contributed for plant growth, promoted better nodulation and effectiveness on biological N fixation.

RESUMO: Este estudo avaliou a atividade de isolados de rizóbios inoculados em sementes pequenas (11 mm) e grandes (18 mm) sobre o crescimento, nodulação e fixação de N de feijão-fava. Isolados selecionados de rizóbios foram comparados com uma estirpe de referência CIAT899 e dois controles sem inoculação. Sementes grandes contribuíram para maior crescimento de plantas, nodulação e fixação de N do que sementes pequenas. Os isolados UFPI-59, UFPI-18 e UFPI-38 promoveram os maiores valores de massa seca de parte aérea e raízes. Os isolados UFPI-32 e UFPI-59 promoveram os maiores valores de número e massa de nódulos, respectivamente. Os isolados UFPI-38 e UFPI-59 promoveram maior acúmulo de N. Este estudo mostrou que o tamanho de sementes influencia o crescimento, nodulação e fixação de N em feijão-fava. Considerando os isolados de rizóbios, UFPI-59, UFPI-38 e UFPI-18 contribuíram para o crescimento de plantas, promoveram melhor nodulação e eficiência na fixação de N.

RESUMEN

This study aimed to assess the occurrence of arbuscular mycorrhizal fungi (AMF) in annatto (Bixa orellana L.) cultivars and their response to AMF inoculation using biometric parameters. The occurrence surveys were conducted in annatto fields in three municipalities from Pernambuco Forest Zone: Lagoa de Itaenga, Gloria de Goitá, and Vitoria de Santo Antão, and in four cultivars (Red Piave, Green Piave, Red Peruvian Paulista, and Green Peruvian Paulista). In a greenhouse, biometric parameters of annatto seedlings of Red Piave, Red Peruvian Paulista, Embrapa-36, and Embrapa-37 cultivars inoculated with AMF isolated from annatto fields. The Red Piave cultivar exhibited greater root colonization than the Green Peruvian Paulista in the Lagoa de Itaenga and Vitoria de Santo Antão municipalities. The cultivar Red Piave showed a more beneficial association with AMF in plants and soil than cultivar Green Peruvian Paulista did, in both Lagoa de Itaenga and Vitoria de Santo Antão. AMF inoculation was effective in promoting the growth of annatto plants, particularly those inoculants with S. heterogama and C. etunicatum.(AU)

RESUMEN

Resumen La región de América Latina se ha convertido en la más afectada del mundo por la pandemia del COVID-19. Y personas con necesidades especiales, población ya vulnerable, están sufriendo un impacto significativo de la crisis actual. Dado que estas personas no pueden dejar de ser protegidas y cuidadas, un grupo de profesores de 10 países de América Latina se reunió para analizar la situación de la odontología para pacientes con necesidades especiales en la región. En todos los países, se evidenció que el confinamiento y las restricciones de desplazamiento están interrumpiendo el acceso a bienes y servicios esenciales para ellos. En cuanto a la odontología, la disposición general es posponer los procedimientos de rutina, a menos que sean clínicamente urgentes o de emergencia; adoptar estrictas medidas de protección personal y evitar o minimizar las intervenciones que puedan producir aerosoles. La atención odontológica remota, teleodontología, se considera como una herramienta fundamental en este momento, ya que permite evaluar la necesidad de atención presencial y ofrecer soporte, información y seguridad a los pacientes y familias. La pandemia nos ha demostrado, a todos, que impulsar la Promoción de la Salud es el verdadero camino, y que no debemos esperar a que se presenten condiciones que afecten la calidad de vida.

Resumo: A região da América Latina tem se tornado a mais afetada do mundo pela pandemia do COVID-19. E as pessoas com necessidades especiais, população já vulnerável, estão sofrendo um impacto significativo da crise atual. Uma vez que essas pessoas não podem deixar de ser protegidas e cuidadas, um grupo de professores de 10 países de América Latina se reuniu para analisar a situação da odontologia para pacientes com necessidades especiais na região. Em todos os países se verificaram que o confinamento e restrições de movimento estavam interrompendo o acesso a bens e serviços essenciais para eles. Para a odontologia, a orientação geral é adiar procedimentos de rotina, a menos que seja clinicamente urgente ou emergencial; adotar medidas rígidas de proteção individual e evitar ou minimizar intervenções que possam produzir aerossóis. O atendimento odontológico à distância, teleodontología, é considerada uma ferramenta fundamental neste momento, pois permite avaliar a necessidade de atendimento presencial e oferecer suporte, informação e segurança aos pacientes e famílias. A pandemia tem demostrado, para todos, que trabalhar na Promoção da Saúde é o verdadeiro caminho, e que não devemos esperar por condições que afetem a qualidade de vida.

Abstract Latin America has become the most affected region by the COVID-19 pandemic in the world. People with special needs-an already vulnerable population-are suffering terrible consequences on account of this crisis. These people need to be protected and cared for at all times. Therefore, a group of lecturers from ten Latin American countries came together to analyze the regional situation of dental care for patients with special needs. Every country shows evidence that lockdowns and movement restrictions interrupt these people's access to essential goods and services. The general course of action regarding dental care is to postpone routine procedures unless they are clinically urgent or an emergency, implement strict personal protection measures and avoid or minimize processes that may produce aerosols. Remote dental care is considered essential these days since it allows practitioners to assess the need for face-to-face care and offer support, information, and safety to patients and families. The pandemic has shown us all that supporting health promotion is the true path and that we should not wait until conditions that affect people's quality of life appear to act.

RESUMEN

Abstract Introduction: this study aimed to describe the profile of the referrals sent to the hospital dentistry team from patients in Hospital Criança Conceição in Porto Alegre, Rio Grande do Sul, Brazil, from January 2012 to July 2018. Methods: a descriptive, retrospective study was conducted, evaluating 193 electronic dental records to extract the following data: patient's sex and age, description of the referral made by other health professionals and the dentist's behavior in solving the presented problem. Results: 61.6% of patients were male and the mean age of all patients was 10.5 years. Most dental referrals came from the oncohematology area (75.12%) and the predominant reason was pre- and post-chemotherapy patients' dental care (40.4%). The diagnosis most commonly found by dentists was mucositis (17.6%) and caries (16%). There was absence of oral diseases in 23.8% of cases. The interventions most commonly performed by the hospital dentistry team were laser therapy (57.5%) and oral hygiene instructions (49.1%) in the hospital setting, while procedures in dental offices and surgical rooms included exodontias (27.7%) and restorations (11.7%). Conclusions: the profile of referrals sent to the hospital dentistry team from patients hospitalized in the Hospital Criança Conceição in Porto Alegre, Rio Grande do Sul, Brazil, is inadequate, since there was a lack of transdisciplinary management including dental care, in addition to poor use of information technology resources and lack of more objective medical records for easy retrieval of patient health information.

Resumen Introducción: este estudio pretende describir el perfil de las interconsultas enviadas al equipo de odontología hospitalaria provenientes de pacientes internados en el Hospital Criança Conceição de Porto Alegre, Rio Grande do Sul, Brasil, en el período de enero de 2012 a julio de 2018. Métodos: estudio descriptive retrospectivo en el que se evaluaron 193 historias clínicas odontológicas electrónicas para extraer los siguientes datos: sexo y edad del paciente, descripción de la interconsulta realizada por otros profesionales de salud y conducta del cirujano dentista frente al problema presentado. Resultados: el 61,6% de los pacientes fue de sexo masculino y la edad promedio general fue 10,5 años. Las interconsultas más solicitadas para los cirujanos dentistas fueron provenientes del área de oncohematología (75,12%) y el motivo predominante fue sobre el cuidado bucal a pacientes pre y posquimioterapia (40,4%). El diagnóstico que más encontraron los dentistas fue mucositis (17,6%) y lesiones de caries (16%). Hubo ausencia de enfermedades bucales en 23,8% de los casos. Las intervenciones más realizadas por el equipo de odontología fueron aplicaciones de laserterapia (57,5%) y orientaciones de higiene bucal (49,1%) en ámbito hospitalario; en sillón dental y sala quirúrgica, fueron exodoncias (27,7%) y restauraciones (11,7%). Conclusiones: el perfil de las interconsultas enviadas al equipo de odontología hospitalaria provenientes de pacientes internados en el Hospital Criança Conceição de Porto Alegre, Rio Grande do Sul, Brasil, es inadecuado, pues se demostró falta de manejo transdisciplinar que incluya odontología, además de la necesidad de un mejor aprovechamiento de los recursos de tecnología de información e historias clínicas más objetivas y que permitan obtener más fácilmente la información de salud de los pacientes.

RESUMEN

Purpose: To assess the survival and risk factors associated with the failure of atraumatic restorative treatment (ART) restorations placed in children with early child-hood caries (ECC).
Methods: The sample consisted of 286 restorations from the records of 137 children treated in a university dental clinic. The date of restoration placement, any reintervention (failure), and the patient's last checkup were recorded. Restoration longevity up to one year of follow-up was assessed via the Kaplan-Meier survival test. Multi-variate Cox regression analysis with shared frailty was used to evaluate the factors associated with failures (P <0.05).
Results: The mean age of the children was 2.3±0.6 years, presenting a decayed, missing, and filled teeth (dmft) mean of 6.3±3.2. Mean survival time was 11.1 months (95 percent confidence interval = 10.8 to 11.4), with 85 percent of the restorations surviving after one year. Caries experience was associated with risk of restoration failure in crude analysis. ART restorations done in children with high caries experience had 2.71 times more risk of failure than those placed in children with moderate caries experience (P=0.03). However, the association lost its significance in the adjusted model (P=0.07).
Conclusion: ART is a patient-friendly approach to manage ECC that promotes satisfactory restoration survival after one year.

RESUMEN

Abstract Objective: To evaluate the prevalence of early childhood caries and its association with Child's Programmatic Action dental visits in a Primary Care Service. Material and Methods: A cross-sectional analytical study was carried out at the Health Centers of the Grupo HospitalarConceição Community Health Service in Porto Alegre, RS, Brazil. Mothers answered a questionnaire containing socioeconomic data, eating habits and oral care of their children. Caries examination was performed by two examiners calibrated using WHO criteria. Results: Eighty-one children with mean age of 58.8 (SD=4.8) months were evaluated, 58% were male. Caries prevalence was 43%, with mean dmft = 1.7 and mean dmfs = 3.09. In the multivariate analysis, there was a statistically significant association of caries with maternal schooling (PR=1.31, 95%CI=1.06-1.62, p=0.012), family income (PR=0.93, 95% CI=0.90-0.97, p<0.001), adequacy of the number of childcare visits (PR=0.68, 95%CI=0.54-0.86, p=0.001) and number of visits to the dentist (PR=1.04, 95%CI=1.01-1.06, p=0.001). Conclusion: Ensuring access to childcare and early dental consultation, while the family context is disregarded, does not seem to be enough to reduce caries. It is necessary to think of non-conventional oral health promotion strategies in Primary Health Care taking into account the territory and social determinants since changes to eating and oral hygiene habits and behaviors are still a challenge to the control of childhood caries.

RESUMEN

The growing need for the use of clean energy has led society to seek alternatives to fossil fuels in order to less pollute the environment. Sugarcane has been known to produce enough biomass and to have associative microorganisms, such as plant growth-promoting bacteria (PGPB), which have the potential to improve the yield of crops. The objective of this study is to evaluate the efficiency and the isotopic dilution of 15N of microbial inoculants containing endophytic diazotrophic bacteria, individually inoculated and in mixture, on productivity, technological quality and biological nitrogen fixation (BNF) of sugarcane variety RB92579. The experiment was conducted for three consecutive years, comprising different crop cycles, in a completely randomized block design with four replications. The evaluations were at 11 months after planting for plant-cane, and at 12 months after cutting for ratoon cane and second ratoon cane. The contribution of BNF by 15N natural abundance technique to inoculated treatments ranged from 18% to 57.31%. This study showed that no strain promoted the improvement on yield and biological nitrogen fixation during the three cycles of sugarcane (plant-cane, ratoon cane and second ratoon cane). However, industrial characteristics of sugar cane can be affectd by PGPB inoculation.
