Abstract Introduction: Spinal injuries are common among young adult men. Recognizing kinematics can help reduce the number of late diagnoses, especially if there are consciousness disorders. Vertebral fractures can be single or multiple, and they are often associated with extravertebral injuries. Objectives: To examine the distribution of the lesion based on the mechanism of production, to characterize the neurological condition, to evaluate the lesion pattern and its relationship with extravertebral lesions, and to analyze the treatment. Materials and Methods: This was a multicenter, prospective study of patients admitted with post-trauma vertebral injuries between July 1, 2018 and June 30, 2020. Age, gender, kinematics, neurological condition, affected sector, pattern of injury, and associated extravertebral injuries were all examined. Results: There were 281 patients (60% men) evaluated, with 400 vertebral and 118 extravertebral lesions. The causes were as follows: polytrauma in 62 cases, falls from great heights in 147 patients, and traffic accidents in 98. ASIA E was the most frequently observed neurological picture (8 cases), which was not determined at admission. The T2-L5 sector was the most affected, mostly by compression injuries. Head and chest trauma were the most common extravertebral injuries; there was one case of SCIWORA and one early death. Conclusions: The most commonly affected spinal sectors were thoracolumbar, thoracic, and lumbar; the injuries are typically caused by falls from great heights and, in general, are isolated, with no neurological injuries. The treatment is determined by the stability and neurological condition.

Resumen Introducción: Las lesiones raquídeas son frecuentes en hombres adultos jóvenes. Reconocer la cinemática ayuda a disminuir la tasa de diagnósticos tardíos, principalmente si hay trastornos de la conciencia. Las fracturas vertebrales pueden ser únicas o múltiples, y asociarse con lesiones extravertebrales. Los objetivos de este estudio fueron analizar la distribución de la lesión según el mecanismo de producción, caracterizar el cuadro neurológico, evaluar el patrón de lesión y la asociación con lesiones extravertebrales, y analizar el tratamiento. Materiales y Métodos: Estudio multicéntrico, prospectivo de pacientes con lesiones vertebrales postrauma, que ingresaron entre el 1 de julio de 2018 y el 30 de junio de 2020. Se analizaron los siguientes parámetros: edad, sexo, cinemática, cuadro neurológico, sector afectado, patrón de lesión, lesiones extravertebrales asociadas. Resultados: Se evaluó a 281 pacientes (60% hombres) con 400 lesiones vertebrales y 118 extravertebrales que, en 62 casos, conformaban un cuadro de politraumatismo; 147 con trauma por caída de altura y 98, por accidente de tránsito. El cuadro neurológico más observado fue ASIA E (8 casos), no determinado al ingreso. El sector T2-L5 fue el más afectado, en su mayoría, por lesiones por compresión. Las lesiones extravertebrales más frecuentes fueron el trauma de cráneo y de tórax; hubo un caso de SCIWORA y un óbito temprano. Conclusiones: Los sectores raquídeos más afectados fueron: el toracolumbar, el torácico y el lumbar; las lesiones suelen deberse a caídas de altura y suelen ser únicas, sin cuadro neurológico. El tratamiento se decide según la estabilidad y el cuadro neurológico.

ABSTRACT Brazil is the largest Coffea arabica L. producer and exporter in the world market. In view of the need for nitrogen fertilization, the objective of this work was to evaluate the use of digital images of coffee leaves as a function of nitrogen concentration and cultivars, as well as to evaluate the most adequate sampling of this technique to predict leaf nitrogen. The experiment was set in a greenhouse, at UNESP - Experimental Campus of Registro-SP, using 12L pots with medium sand. A completely randomized design was adopted, in a 4 x 2 factorial scheme, with four concentrations of N (0, 50, 100 and 200 mg dm-3), and two coffee cultivars (Mundo Novo and Obatã), with ten replications. The variables evaluated were: hue, dark green color index (DGCI), leaf area and leaf nitrogen content. The hue and DGCI were influenced by N concentration, cultivar and are dependent on the day after treatment application and the number of leaves used. The use of five leaves per replication was more adequate to estimate leaf N content. Hue, DGCI and leaf area were higher in Obatã depending on the day after application of the treatment and N concentration.

ABSTRACT Introduction: Pediatric heart transplantation is the definitive therapy for children with end-stage heart failure. This paper describes our initial experience in pediatric heart transplantation in a tertiary center in Brazil Methods: This is a historical prospective descriptive cohort study based on a review of the medical records of children undergoing heart transplantation at Hospital de Base and Hospital da Criança e Maternidade de São José do Rio Preto. Variables were displayed as frequency, mean, or median. Statistical analysis and Kaplan-Meier actuarial curve were obtained with the aid of Microsoft® Excel® 2019 and STATSDirect version 3.3.5. Results: Between January 2010 and December 2020, ten children underwent bicaval orthotopic heart transplantation, 30% of which were under one year of age. Nine patients had end-stage heart failure (International Society for Heart and Lung Transplantation-Heart Failure D) and 50% of the recipients were transplanted under conditions of progressive clinical deterioration (Interagency Registry for Mechanically Assisted Circulatory Support ≤ 2). Forty percent of the recipients had a panel-reactive antibody > 20% on virtual crossmatch. In the postoperative period, 80% of patients required high dose of inotropic support (vasoactive-inotropic score > 10) for > 48 hours. The death-free survival rate at 131 months was 77.1±14.4%. Most patients (88.9%) in late follow-up had an episode of active cytomegalovirus infection. Cellular rejection, with or without clinical repercussion, was present in 44.4% of the patients. Conclusion: Pediatric heart transplantation produces acceptable and feasible outcomes as definitive therapy for children with end-stage heart failure.

RESUMO Introdução: O abscesso peridural piogênico da coluna (PSEA) é de difícil diagnóstico e pode ter consequências devastadoras. A ressonância magnética (RM) tem alta sensibilidade e especificidade, que são aumentadas ainda mais com contraste. Existem várias classificações dos processos infecciosos vertebrais, com ênfase em espondilodiscite. Objetivo: Analisar os parâmetros morfológicos e sua reprodutibilidade; e analisar as diferentes sequências de imagens de ressonância. Métodos: A partir de um banco de imagens, foi planejada uma classificação morfológica do PSEA, com cinco parâmetros: Região (R) que indica os limites superior e inferior do abscesso; Localização (U), indicando se o abscesso é anterior ou posterior dentro do canal; Comprometimento (C), meníngeo ou de conteúdo das estruturas; Associação (A), discite, osteomielite ou ambas e Perivertebral (P), abscesso extravertebral anterior, lateral ou posterior. Os três primeiros parâmetros dão uma ideia do volume da PSEA, enquanto os dois últimos mostram os focos infecciosos relacionados. Trinta e cinco casos foram analisados usando o coeficiente de Kappa. Resultados: A reprodutibilidade global intra e interobservador foi Kappa 0,81. Os resultados para cada parâmetro foram os seguintes: R = 0,95, U = 0,92, C = 0,66, A = 0,70 e P = 0,80. Os três primeiros dão uma noção de volume e os dois últimos se relacionam com a presença de focos infecciosos vertebrais fora do canal. A RM ponderada em T2 com contraste foi considerada a sequência de imagens mais eficaz. Conclusões: A classificação morfológica é simples de usar e tem excelente reprodutibilidade. Os parâmetros com maior reprodutibilidade foram região e localização com valores > 0,92. A adição do contraste de gadolínio aumentou a sensibilidade do diagnóstico; o uso de imagens sagitais e axiais em RM T2 foi a sequência de imagens mais sensível. Nível de Evidência III; Original.

ABSTRACT Background: Pyogenic Spinal Epidural Abscess (PSEA) is difficult to diagnose and can have devastating consequences. Magnetic Resonance Imaging (MRI) has high sensitivity and specificity, which are further increased with the use of contrast. There are several classifications of vertebral infectious processes, with emphasis on spondylodiscitis. Objective: To analyze the morphological parameters and their reproducibility; and to analyze different resonance imaging sequences. Methods: Using an image database, a morphological classification of PSEA was planned, with five parameters: Region (R), indicating the upper and lower limits of the abscess; Location (U), indicating whether the abscess is anterior or posterior within the canal; Compromise (C), meningeal or content of the structures; Association (A), discitis, osteomyelitis or both; and Perivertebral (P), anterior, lateral or posterior extravertebral abscess. The first three parameters give an idea of the volume of the PSEA, while the last two give the related infectious foci. Thirty-five cases were analyzed using Kappa’s coefficient. Results: The global intra- and interobserver reproducibility was Kappa 0.81. The results for each parameter were as follows: R=0.95, U=0.92, C=0.66, A=0.70 and P=0.80. The first three give a notion of volume and the last two relate to the presence of vertebral infectious foci outside the canal. T2 weighted MRI with contrast was found to be the most effective imaging sequence. Conclusion: The morphological classification is simple to use, with excellent reproducibility. The parameters with the highest reproducibility were region and location, with values >0.92. The addition of gadolinium contrast increased the sensitivity of the diagnosis; the use of sagittal and axial images in T2-MRI was the most sensitive imaging sequence. Evidence Level III; Original.

Abstract Context Aging causes a progressive worsening in postural balance, affecting functional independence and increasing the risk of falls. Objective The aim of the study was to evaluate the effect of aging on the static balance in women from 50-years to 89-years of age. Design This was a cross-sectional study, with 400 irregularly active women were evaluated and grouped by age: Group 6thdecade (age 50 to 59) ‒ 58 participants; Group 7thdecade (age 60 to 69) ‒ 214 participants; Group 8thdecade (age 70 to 79) ‒ 92 participants; Group 9thdecade (age 80 to 89) ‒ 36 participants. Postural balance was evaluated using a portable force platform in a standard standing position, with Eyes Open (EO) and Eyes Closed (EC). Results In the two measurement conditions, the elderly women in Group 9thdecade presented mediolateral displacement and range, and mean velocity greater than the women's values in Groups 6thand 7thdecade. In the EO e EC situation, the displacement was higher in the elderly Group 9thdecade compared to younger groups. Group 8thhas a mean velocity greater than Group 6thdecade in the EO situation. Conclusions Posturography showed a decline in postural balance with advancing age, suggesting that the 9thdecade of life is a borderline age to this detriment due to an increase in postural instability.

Resumo: A densidade mineral óssea é um fator crucial no sucesso ou falha da osteossíntese na cirurgia da coluna vertebral; isso mostra o aparecimento da osteoporose e complicações relacionadas a ela. Sua avaliação é verificada por absorptiometria de raios-X de dupla energia (DEXA) e medição da Unidade Hounsfield (HU) por tomografia. Objetivo: Determinar o uso do HU no planejamento cirúrgico; comparar utilidade no diagnóstico de osteoporose pelo DEXA; e avaliar a sensibilidade na previsão de complicações. Método: Foi realizada uma revisão de literatura sistêmica no PubMed, em consonância com a metodologia PRISMA. Incluindo aqueles que justificaram o uso do planejamento pré-cirúrgico, comparou o HU/DEXA e avaliaram complicações. Para a análise estatística, o χ2 foi usado. Resultados: Inicialmente foram identificados 57 artigos por meio da seleção de nove que atenderam aos critérios de inclusão. Em pacientes submetidos à cirurgia espinhal para fixação e fusão por patologia degenerativa, a medição do HU apresentou prevalência de osteoporose de 58,5% (sensibilidade 93,26%; especificidade 90,22%), complicações associadas à osteoporose de 24,5%, diagnóstico adequado de 71,98% e taxa de liberação de parafusos de 82,31%. Conclusões: A medição da UH para o diagnóstico da osteoporose acaba sendo mais sensível, específica e preditiva em relação ao DEXA, principalmente em pacientes idosos; representa uma ferramenta útil no planejamento da cirurgia espinhal, minimizando o risco de complicações como liberação de parafusos, fraturas, pseudoartrose, subsidência de dispositivos intersomáticos e cifose da junção proximal. Nível de evidência II; Revisão Sistemática e meta-análise.

ABSTRACT Bone mineral density is a crucial factor in the success or failure of osteosynthesis in spine surgery; it shows the onset of osteoporosis and related complications. Its evaluation is verified by dual-energy X-ray absorptiometry (DEXA) and Hounsfield Unit (HU) measurement by CT scan. Objective: Determine the use of HU in surgical planning; compare utility in diagnosing osteoporosis by DEXA; and evaluate sensitivity in predicting complications. Method: A systemic literature review was conducted on PubMed, in line with PRISMA methodology. Including those who justified the use of pre-surgical planning, compared HU/DEXA, and assessed complications. For the statistical analysis, the χ2 was used. Results: 57 articles were identified by selecting nine that met the inclusion criteria. In patients undergoing spinal surgery for fixation and fusion for degenerative pathology, HU measurement showed a prevalence of osteoporosis of 58.5% (sensitivity 93.26%; specificity 90.22%), osteoporosis-associated complications of 24.5%, proper diagnosis of 71.98%, and screw release rate of 82.31%. Conclusions: UH measurement for the diagnosis of osteoporosis turns out to be more sensitive, specific, and predictive compared to DEXA, especially in elderly patients; it represents a useful tool in planning spinal surgery, minimizing the risk of complications such as screw release, fractures, pseudoarthrosis, subsidence of intersomatic devices, and kyphosis of the proximal junction. Level of evidence II; Study Design: Systematic Review and meta-analysis.

Abstract: At present, the possibility of communicating or expressing oneself through an electronic medium is very wide: most users of computers and mobile devices use email, social networks, chats and other tools. One of the problems that has arisen with this form of communication is excess, such as plagiarism, false identity, intimidating notes, and others. The attribution of authorship of texts (AAT) is responsible for answering the question of who is the author of a text, giving some previous examples of that author (training set). A useful process within the AAT is the identification of gender or sex (male, female) and that has been studied by several authors, but mainly for English. The present work proposes a computational model based on lexical characteristics (n-grams) for the identification of the genre for short texts in Spanish. Tests were made with a corpus of text messages on social networks and blogs, obtaining promising results.

Resumen: En la actualidad, la posibilidad de comunicarse o de expresarse por un medio electrónico es muy amplia: correo electrónico, redes sociales, chats y otras herramientas son usadas por la mayoría de los usuarios de computadoras y dispositivos móviles. Uno de los problemas que se ha presentado con esta forma de comunicación es el exceso, como el plagio, falsa identidad, notas intimidatorias, etc. La atribución de autoría de textos (AAT) se encarga de responder a la cuestión de quién es el autor de un texto, dando algunos ejemplos previos de ese autor (conjunto de entrenamiento). Un proceso útil dentro de la AAT es la identificación de género o sexo (hombre, mujer) y que ha sido estudiado por varios autores, pero principalmente para el inglés. El presente trabajo propone un modelo computacional basado en características léxicas (n-gramas) para la identificación del género para textos cortos en español. Se hicieron pruebas con un corpus de textos de mensajes en redes sociales y blogs, obteniendo resultados prometedores.

Background: Creutzfeldt-Jakob disease (CJD) is a prion affection that typically produces a rapidly progressive dementia with different neurologic and extra-neurologic manifestations. Aim: To characterize clinical, imaging and electroencephalography findings in patients with a probable CJD. Patients and Methods: A case series study of patients admitted in the Neurology department at a public hospital, between 2014 and 2019. Demographic, clinical, imaging, and electroencephalographic data of patients with probable CJD were analyzed. Results: Seventeen patients aged 63 ± 11 years (53% women) with a probable CJD were gathered. The incidence was 4.7 cases/year per million inhabitants. Twenty four percent of patients had a family history of CJD. The median time between the onset of symptoms and the hospital admission was three months with a survival of four months. The most common clinical manifestations were an amnesic syndrome in 88%, myoclonus in 76%, frontal syndrome and ataxia in 71%. Brain MRI was abnormal in all patients. The preponderant finding was the involvement of the caudate nucleus in 82% of cases. In the EEG, 94% of patients had abnormalities. All had a theta-delta slowing as a base rhythm. The pseudo-periodic pattern was observed in the 29% and status epilepticus in 18%. Conclusions: In this group of patients we observed the heterogeneity of the clinical manifestations of the disease, the frequent imaging and electroencephalographic alterations and the short evolution time leading to death.

Abstract Objective: the aim of this study was to assess weight loss, diet prescribed, and nutritional status in hospitalized patients, as well as their associated factors. Methods: weight loss during hospitalization, nutritional status, disease type, and prescribed diet were investigated in a retrospective study in 621 hospitalized patients. The chi-squared, Fisher's, Mann-Whitney, and Kruskal-Wallis tests were used for statistical analysis. To identify factors associated with weight loss a logistic regression analysis was performed. The significance level adopted for statistical tests was 5 %. Results: patients who experienced weight loss during hospitalization were associated with longer hospital stays (p < 0.0001; OR = 1.052; 95 % CI = 1.030 to 1.073), malnourishment according to the subjective global assessment (p = 0.0358; OR = 1.520; 95 % CI = 1,028 to 2,248), digestive disorders (p = 0.0081; OR = 3.177; 95 % CI = 1.351 to 7.469), and digestive neoplasms (p = 0.0407; OR = 2.410; 95 % CI = 1.038 to 5.597). Conclusion: weight loss during hospitalization was associated with neoplasms, digestive diseases, malnutrition, and length of stay.

Resumen Objetivo: el objetivo de este estudio fue evaluar la pérdida de peso, la dieta prescrita y el estado nutricional de pacientes hospitalizados y sus factores asociados. Métodos: se investigó la pérdida de peso durante la hospitalización, el estado nutricional, el tipo de enfermedad y la dieta prescrita en un estudio retrospectivo de 621 pacientes hospitalizados. Las pruebas del chi cuadrado, Fisher, Mann-Whitney y Kruskal-Wallis se utilizaron para el análisis estadístico. Para identificar los factores asociados con la pérdida de peso se utilizó la regresión logística. El nivel de significación adoptado para las pruebas estadísticas fue del 5 %. Resultados: los casos de pérdida de peso durante la hospitalización se asociaron a las estancias hospitalarias más largas (p < 0,0001; OR = 1,052; IC 95 % = 1,030; 1,073), la desnutrición según la evaluación global subjetiva (p = 0,0358; OR = 1,520; IC 95 % = 1,028; 2,248) los trastornos digestivos (p = 0,0081; OR = 3,177; IC 95 % = 1,351; 7,469) y las neoplasias digestivas (p = 0,0407; OR = 2,410; IC 95 % = 1,038; 5,597). Conclusión: la pérdida de peso durante la hospitalización se asoció con las neoplasias y las enfermedades digestivas, la desnutrición y la duración de la estancia.

Resumen: En | Texto: En | PDF: En

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

Resumen: En | Texto: En | PDF: En

Abstract: The aim of the present study was to analyze the epidemiology of maxillofacial odontogenic and non-odontogenic cysts diagnosed for 30 years in a Brazilian population. A retrospective descriptive cross-sectional study was performed. Biopsy records were obtained from the archives of a Brazilian referral center between 1989 and 2019. Data regarding age, gender, anatomical location, and histopathological diagnosis were collected and categorized. Further, a literature search for similar studies was performed. A total of 6.994 biopsy records were evaluated, but only 367 (5.24%) cases were classified as odontogenic cysts (OC) or non-odontogenic cysts (NOC). Among all cystic lesions, 341 cases (92.9%) were OC and 26 cases (7.1%) were NOC. These lesions were more common in females (n = 208 / 56.67%) and located mostly in the mandible (n = 195 / 53.1%). In patients with OC, the radicular cyst was the most frequent (n = 134 / 36.5%), followed by the dentigerous cyst (n = 101 / 27.5%) and the odontogenic keratocyst (n = 52 / 14.2%). Patients with NOC had a higher frequency of epidermoid cyst (n = 12 / 3.3%), oral lymphoepithelial cyst (n = 7 / 1.9%), and nasopalatine duct cyst (n = 4 / 1.1%). The OCs were more prevalent than NOCs, and inflammatory cysts were the most common among all the OCs.

Resumen: En | Texto: En | PDF: En

OBJECTIVES: To evaluate the clinical characteristics, ground reaction force (GRF), and function of the plantar muscles and dorsiflexors of the ankle in runners with and without Achilles tendinopathy (AT) and in non-runners. METHODS: Seventy-two participants (42 men, 30 women; mean age: 37.3±9.9 years) were enrolled in this cross-sectional study and divided into three groups: AT group (ATG, n=24), healthy runners’ group (HRG, n=24), and non-runners’ group (NRG, n=24). Both ankles were evaluated in each group. The American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale was used for clinical and functional evaluation. GRF was evaluated using force plates and muscle strength was evaluated using an isokinetic dynamometer. RESULTS: The AOFAS scores were lower in the ATG. The strike impulse was higher in the ATG than in the HRG and NRG. However, GRF was similar among the groups. The ATG exhibited lower total work at 120°/s speed than the HRG. The peak torque in concentric dorsiflexion was lower in the NRG than in the ATG and HRG. The peak torque and total work in concentric plantar flexion were lower in the NRG than in the ATG. The peak torque and total work in eccentric plantar flexion were lower in the NRG than in the ATG and HRG. CONCLUSION: Runners with AT showed higher strike impulse, lower muscle strength of the plantar flexors, and higher clinical and functional damage.

ABSTRACT: This study aims to determine the intention of future behavior of undergraduate students, concerning the Sustainable Development Goals (SDGs), which is based on the Theory of Planned Behavior. The methodology applied refers to a non-experimental cross-sectional cohort research statistically modeled from structural equations. 213 students from a Chilean Public University were evaluated. The research data were tabulated considering the variables intention, attitude, subjective norm and Perceived Behavioural Control (PBC). The results of the hypothesized model partially support the validity of the Theory of Planned Behavior, that is, the intention of the students determined by the individual beliefs and motivations of the individual. The findings must be understood according to the limitations of the study. Finally, the implications and future lines of research are presented.

RESUMEN: Este estudio tiene como propósito determinar la intención del comportamiento futuro de estudiantes de pregrado, con respecto a los Objetivos de Desarrollo Sostenible (ODS), la que es fundamentada a partir de la Teoría del Comportamiento Planificado. La metodología que se aplica se refiere a una investigación no experimental de cohorte transversal modelado estadísticamente a partir de ecuaciones estructurales. Se evaluaron a 213 estudiantes de una Universidad Pública Chilena. Los datos de investigación se tabularon considerando las variables intención, actitud, norma subjetiva y control del comportamiento percibido (PBC). Los resultados del modelo hipotetizado apoyan parcialmente la validez de la Teoría del Comportamiento Planificado, esto es la intención de los estudiantes determinada por las creencias individuales y motivaciones propias del individuo. Los hallazgos deben ser comprendidos de acuerdo a las limitaciones del estudio. Finalmente, se presentan las implicancias y las futuras líneas de investigación.
