RESUMEN

Fermented soybean grain (FSBG) is considered improper to use as a protein source in animal nutrition, since it is assumed that defects cause changes on its chemical composition and favor mycotoxins production, but chemical composition data does not support this theory and in vivo studies are missing. Thus, this study aimed to evaluate the effects of FSBG in feedlot lamb diets. For that, two types of FSBG (partially fermented and completely fermented, PFSBG and CFSBG) and one standard soybean grain (SSBG) were obtained and evaluated alone or as a component of experimental diets by in vitro and in vivo studies, where FSBG totally replaced SSBG in feedlot lamb diets, which was included in the experimental diets in 17.4% on dry matter basis as protein source. Before the studies, both soybeans were sent to a specialized laboratory where no mycotoxins were detected. As a result, lower DM and carbohydrate contents but higher crude protein, fiber, and indigestible NDF contents were measured in CFSBG than in SSBG. Furthermore, both types of FSBG showed lower digestibility in vitro dry matter (IVDMD) than SSBG when evaluated separately; however, when evaluated in experimental diets, the substitution of SSBG for FSBG did not affect IVDMD. It was also observed that FSBG also had less rumen-degradable protein than SSBG (mean 47.9 vs 86.4%). In the in vivo study, FSBG did not affect nutrient intake, apparent digestibility, or animal performance (i.e., average daily gain and carcass gain). Thus, mycotoxins-free FSBG may be an alternative to totally replace SSBG in feedlot lamb diets.

RESUMEN

The Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) is a simple, feasible, and sensitive questionnaire developed in English for assessing the health status (symptoms, function, and quality of life) of patients with heart failure (HF). We aimed to assess the internal consistency and construct validity of the Portuguese version of KCCQ-12. We administered the KCCQ-12, the Minnesota Living Heart Failure (MLHFQ), and the New York Heart Association (NYHA) classification by telephone. Internal consistency was assessed with Cronbach's Alpha (α-Cronbach) and construct validity with correlations to the MLHFQ and NYHA. Internal consistency was high (α-Cronbach = 0.92 for the Overall Summary score and 0.77-0.85 for the subdomains). Construct validity was supported by finding high correlations between the KCCQ-12 Physical Limitation and the Symptom Frequency domains with the physical domain of the MLHFQ (r = -0.70 and r = -0.76, p < 0.001 for both) and the Overall Summary scale with NYHA classifications (r = -0.72, p < 0.001). The Portuguese version of KCCQ-12 has high internal consistency and shows a convergent construct validity with other measures quantifying the health status of patients with chronic HF and can be used confidently in Brazil for research and clinical care.

RESUMEN

BACKGROUND: Genetic variability is the most important parameter in plant breeding based on selection. There is a need for morpho-agronomic and molecular characterization of Passiflora species, to exploit their genetic resources more efficiently. No study has yet been carried out to compare half-sib and full-sib families in relation to the magnitude of the genetic variability obtained in them, and then to elucidate the advantages or disadvantages of each one. METHODS AND RESULTS: In the present study, SSR markers were used to evaluate the genetic structure and diversity of half-sib and full-sib progenies of sour passion fruit. Two full-sib progenies (PSA and PSB), and a half-sib progeny (PHS), together with their parents, were genotyped with a set of eight pairs of SSR markers. Discriminant Analysis of Principal Components (DAPC) and Structure software were used to study the genetic structure of the progenies. The results indicate that the half-sib progeny has lower genetic variability, although it has higher allele richness. By the AMOVA most of the genetic variability was found within the progenies. Three groups were clearly observed in the DAPC analysis, while two hypothetical groups (k = 2) were observed in the Bayesian approach. The PSB progeny showed a high genetic mixture between the PSA and PHS progenies. CONCLUSION: Lower genetic variability is found in half-sib progenies. The results obtained here allow us to suppose that the selection within full-sib progenies will possibly provide better estimates of genetic variance in sour passion fruit breeding programs, since they provide greater genetic diversity.

RESUMEN

PURPOSE OF REVIEW: As transcatheter edge-to-edge mitral valve repair (TEER) evolves and indications broaden to include younger and lower surgical risk patients, it is essential to understand TEER failure trends and potential impact on subsequent mitral valve surgery, especially when pertaining to feasibility of durable valve reconstruction as opposed to de-novo repair. RECENT FINDINGS: Results of the two largest series analysing mitral valve surgery following TEER have demonstrated remarkably low repairability rates with consequent need for valve replacement. Post TEER surgery was associated with high early and late mortalities, likely as a reflection of patient baseline characteristics and acuity of surgery. Presence and correction of concomitant cardiac pathologies were a frequent finding. Centre and surgeon volumes were important factors in optimizing the likelihood of salvage repair and reducing perioperative risks. SUMMARY: Surgical mitral valve repair in reference centres remain the gold standard and the most durable treatment for degenerative mitral disease with excellent perioperative safety outcomes. Given the high likelihood of needing high-risk mitral valve replacement when TEER fails, consideration for potentially less durable transcatheter alternatives should be taken with caution in younger or lower surgical risk patients.

RESUMEN

OBJECTIVE: The leadless cardiac pacemaker is typically implanted percutaneously and has been widely used for patients who have already undergone valve surgery. We sought to determine the feasibility and safety of implanting the leadless pacemaker under direct visualization during valve surgery. METHODS: We performed a retrospective analysis of consecutive adult patients (n = 15) who underwent implantation of a leadless pacemaker under direct visualization at the time of valve surgery. Indications for single-chamber pacing were sick sinus syndrome with pauses (53.3%), atrial fibrillation with slow ventricular rates (13.3%) or complete heart block (6.6%), and elevated risk for postoperative heart block (26.6%). Leadless pacemaker performance and pacing percentage were assessed. RESULTS: Patients' age was 67.5 ± 17 years, 6 patients (40%) were male, and 14 patients (93%) had atrial fibrillation. Isolated tricuspid valve replacement was performed in 5 patients (33.3%), and the remainder underwent multivalve surgery that included concomitant tricuspid valve repair/replacement. In 93% of the patients (n = 14), the immediate post-cardiopulmonary bypass pacing thresholds were normal (≤2.0 V at 0.24 ms) and normalized in the remaining patient by the next morning. The impedance/sensing values were normal and stable through follow-up (151 ± 119 days) in all patients. Reliable leadless pacemaker performance allowed for deferral of temporary epicardial wires in 11 patients (73%). There were no procedural complications or device malfunction. CONCLUSIONS: Leadless cardiac pacemaker implantation during valve surgery is feasible and safe. This hybrid approach to pacing may simplify the perioperative management of patients undergoing valve surgery who have an indication for single-chamber pacing.

RESUMEN

Introduction: In view of the syphilis epidemic that Brazil is experiencing and the need to strengthen the discourse on preventing this sexually transmitted infection (STI), the campaign "Eu sei, você sabe?" (I know. Do you know?) was conducted for dissemination of the pieces on social media. Objective: The of aim of this study was to perform a qualitative descriptive analysis of the posts published on the social network Instagram of the National Campaign to Fight Syphilis 2020-21 aimed at young people. Methods: The analysis performed was based on the method suggested by Eliseo Véron and aimed to establish relationships between the "reading contracts" offered and the processes of focusing (strong direct relevance) and defocusing (interdiscursive relevance) acting in the messages with the results of the communication indicator "Reach/Exposure". Results: The analysis was conducted from October 2020 to April 2021. In all, 31 cards were published. Among them, eight publications presented in their content a discourse directed at young people including individuals in the 20-29 age bracket. In general, the pieces provided a common proposal of visual structuring and aimed to address the deficiencies identified in previous campaigns developed and presented in the perspective of the project itself, as well as the propositions established by control agencies for dealing with syphilis in Brazil. Conclusion: Some hypotheses raised on the basis of the analysis were as follows. There is the possibility that the distinction between grammars of production and recognition produce negotiations or resistance to the meaning of the interpellation contained in the theme "Sífilis. Eu sei. Você sabe?" Even if the characters presented in the cards did not include some specific audiences, such as young transgenders, the language offered can generate empathy in these audiences. The production strategies of cards with a more visual aesthetic and added to a predominantly graphic distribution of important information possibly contributed to a greater reach/impact on the social network audience.


Introdução: Diante da epidemia de sífilis vivida pelo Brasil e tendo em vista a necessidade de fortalecer o discurso de prevenção dessa infecção sexualmente transmissível, realizou-se a campanha "Eu sei. Você sabe?", voltada para divulgação das peças nas redes sociais digitais. Objetivo: Este trabalho objetiva realizar análise qualitativa descritiva das postagens publicadas na rede social Instagram da Campanha Nacional de Combate à Sífilis 2020-21, destinadas ao público jovem. Métodos: A análise realizada baseia-se na metodologia sugerida por Eliseo Véron e visa estabelecer relações entre os contratos de leitura ofertados e os processos de focalização (pertinência forte direta) e desfocalização (pertinência interdiscursiva) atuantes nas mensagens com os resultados do indicador de comunicação alcance/exposição. Resultados: A análise adotou o recorte temporal de outubro/2020 até abril/2021. Ao todo 31 cards foram publicados. Entre eles, oito publicações apresentaram em seu conteúdo um discurso direcionado ao público jovem, como também personagens na faixa etária entre 20 e 29 anos. De maneira geral, as peças trazem uma proposta comum de estruturação visual e visam contemplar as deficiências identificadas em campanhas anteriores desenvolvidas e apresentadas na perspectiva do próprio projeto, bem como das proposições estabelecidas por órgãos de controle para o enfrentamento da sífilis no Brasil. Conclusão: Algumas hipóteses levantadas com base na análise realizada: há a possibilidade de que a distinção entre gramáticas de produção e reconhecimento produza negociações ou resistências ao sentido da interpelação contida no tema "Sífilis. Eu sei. Você sabe?"; mesmo que as personas apresentadas nos cards não englobem alguns públicos específicos, como jovens transgêneros, a linguagem ofertada pode gerar empatia nesses públicos; as estratégias de produção de cards com estética mais visual e somados a uma distribuição das informações importantes predominantemente gráfica possivelmente contribuíram para maior alcance/impacto no público das redes sociais.

RESUMEN

OBJECTIVE: The objective of this study was to compare the hypoalgesic effects of isolated or combined use of transcutaneous electrical nerve stimulation (TENS) and cervical joint manipulation (JM) in asymptomatic participants. METHODS: One hundred and forty-four healthy participants aged 18 to 30 years old were randomly assigned to 1 of 4 groups (n = 36 per group): active TENS + active JM, active TENS + placebo JM, placebo TENS + active JM, and placebo TENS + placebo JM. Active or placebo TENS was applied to the dominant forearm. JM was applied to the C6-7 segments. The pressure pain threshold was measured pre- and postintervention and after 20 minutes on the forearm and tibialis anterior of the dominant side. RESULTS: Segmental hypoalgesia was greater in the group active TENS + active JM compared with active TENS + placebo JM (P = .002), placebo TENS + active JM (P < .0001), and placebo TENS + placebo JM (P < .0001). For the extrasegmental hypoalgesia, active TENS + active JM had greater hypoalgesic effect compared with active TENS + placebo JM (P = .033), placebo TENS + active JM (P = .002), and placebo TENS + placebo JM (P < .0001). CONCLUSION: TENS and JM produced hypoalgesia when used alone and, when the treatments were combined, a higher segmental and extrasegmental hypoalgesic effect was obtained in asymptomatic participants.

RESUMEN

Systemic inflammatory response and hemodilution are prominent factors associated with cardiopulmonary bypass and result in increased morbidity and mortality in children. Miniaturized systems have evolved to decrease such effects and restrict use of blood products, especially in the neonatal population. We have developed a table mounted cardiopulmonary bypass system that allows closer proximity of the system to the patient with consequent decrease in priming volumes, hemodilution, and its associated effects, and contributes to development into an ideally bloodless surgical approach.

RESUMEN

INTRODUCTION: Due to late complications associated with the use of conventional prosthetic heart valves, several centers have advocated aortic valve repair and/or valve sparing aortic root replacement for patients with aortic valve insufficiency, in order to enhance late survival and minimize adverse postoperative events. METHODS: From March/2012 thru March 2015, 37 patients consecutively underwent conservative operations of the aortic valve and/or aortic root. Mean age was 48±16 years and 81% were males. The aortic valve was bicuspid in 54% and tricuspid in the remaining. All were operated with the aid of intraoperative transesophageal echocardiography. Surgical techniques consisted of replacing the aortic root with a Dacron graft whenever it was dilated or aneurysmatic, using either the remodeling or the reimplantation technique, besides correcting leaflet prolapse when present. Patients were sequentially evaluated with clinical and echocardiographic studies and mean follow-up time was 16±5 months. RESULTS: Thirty-day mortality was 2.7%. In addition there were two late deaths, with late survival being 85% (CI 95% - 68%-95%) at two years. Two patients were reoperated due to primary structural valve failure. Freedom from reoperation or from primary structural valve failure was 90% (CI 95% - 66%-97%) and 91% (CI 95% - 69%-97%) at 2 years, respectively. During clinical follow-up up to 3 years, there were no cases of thromboembolism, hemorrhage or endocarditis. CONCLUSIONS: Although this represents an initial series, these data demonstrates that aortic valve repair and/or valve sparing aortic root surgery can be performed with satisfactory immediate and short-term results.

RESUMEN

Native of the Americas, pitaya is currently a fruit bearing plant in expansion in the domestic and international market and is an alternative source of revenue for small and large farmers. As some studies show the lack of efficiency of natural pollinators in fructification in pitaya, the purpose of this study was to evaluate the efficiency of manual self-pollination and of manual cross pollination in Hylocereus undatus in two periods of pollination. The experiment was carried out in the orchard of the Universidade Federal de Lavras (Federal University of Lavras) in a completely randomized design with a 2 x 2 factorial arrangement (two types of pollination and two flowering periods) with 15 replications, with one flower per replication. The flowers were bagged, emasculated and pollinated manually. The percentage of fruit set , longitudinal and transversal diameter of the fruit, mass of the fruit, pulp and peel, thickness of the peel, soluble solids contents, pH, titratable acidity, ratio (soluble solids:titratable acidity), number of seeds per fruit and seed germination were evaluated. It may be concluded that pollination in red pitaya with its own pollen allows fructification. Flowers pollinated in Apr. result in fruit with physical characteristics superior to the fruit generated by pollination in Jan.


Nativa das Américas, a pitaia é atualmente uma frutífera em expansão no mercado nacional e internacional, sendo uma alternativa de renda aos pequenos e grandes produtores. Como alguns estudos demonstram a ineficiência de polinizadores naturais na frutificação da pitaia, realizou-se este trabalho objetivando-se estudar a eficiência da autopolinização manual e da polinização manual cruzada em Hylocereus undatus, em duas épocas. O experimento foi instalado no pomar da Universidade Federal de Lavras, em delineamento inteiramente casualizado, em esquema fatorial 2 x 2 (dois tipo de polinização e duas épocas de florescimento), com 15 repetições, sendo um flor por repetição. As flores foram ensacadas, emasculadas e polinizadas manualmente. Foram avaliadas a percentagem de pegamento dos frutos, diâmetro longitudinal e transversal dos frutos, massa de fruto, polpa e casca, espessura de casca, teores de sólidos solúveis, pH, acidez titulável, ratio (sólidos solúveis:acidez titulável), número de sementes por fruto e germinação das sementes. Concluiu-se que a polinização em pitaia vermelha com o próprio pólen permite a frutificação. Flores polinizadas em abril resultam em frutos com características físicas superiores aos frutos gerados em janeiro.

RESUMEN

Manipulation of the spinal column is a manual therapeutic resource characterized by passive thrust of a given joint at a high velocity and low amplitude within the limits of anatomic integrity. The objective of the present study was to assess the immediate effects of upper thoracic manipulation on skin temperature in the vertebral region in healthy women. Thus, a randomized controlled blind trial was realized in the university community. Twenty-six healthy women were randomly allocated into an experimental group (n=13) and a placebo group (n=13). A single session of upper thoracic spine manipulation (segment T3) was performed. Infrared thermography was used to determine changes in skin temperature in the vertebral region. Images were taken prior to, immediately after and both five and 10 minutes after manipulation. Two-way repeated measures analysis of variance with post hoc Bonferroni test was used for inter and intragroup comparisons. The level of significance was set to 5%. No significant differences were found between the different evaluation times in either group (p>0.05). In the intergroup analysis, no statistically significant differences were found in any of the comparisons (p>0.05). Based on the method employed, thoracic spine manipulation of the T3 vertebral segment does not promote changes in skin surface temperature in the region manipulated in asymptomatic individuals.


A manipulação da coluna vertebral é um recurso da terapia manual caracterizado por um impulso passivo de alta velocidade e baixa amplitude dentro dos limites de integridade anatômica de uma articulação (thrust). O objetivo do presente estudo foi avaliar os efeitos imediatos da manipulação torácica alta sobre a temperatura superficial cutânea da região vertebral em mulheres saudáveis. Para tal, foi realizado um estudo clínico randomizado cego na comunidade universitária. Vinte e seis voluntárias saudáveis foram alocadas de forma randomizada em um grupo experimental (n=13) e um grupo placebo (n=13). Uma sessão de manipulação torácica alta (segmento T3) foi realizada. Foi empregada a termografia infravermelha para determinar alterações na temperatura cutânea na região vertebral. Imagens foram capturadas antes, imediatamente após, cinco e dez minutos após a manipulação. Foi usada análise de variância com medidas repetidas (dois critérios) seguida do teste de Bonferroni para as comparações inter e intragrupos. Adotou-se um nível de significância de 5%. Não foi encontrada diferença significativa nas diferentes avaliações ao longo do tempo (p>0,05). Na análise intergrupos, não foi constatada diferença significativa nas comparações realizadas (p>0,05). Com base na metodologia empregada, a manipulação torácica do segmento vertebral T3 não promoveu alterações na temperatura superficial cutânea na região manipulada.


La manipulación de la espina dorsal es un recurso de terapia manual que se caracteriza por un impulso pasivo de alta velocidad y baja amplitud de los límites de integridad anatómica de una articulación (thrust). Esta investigación tuvo por objetivo evaluar los efectos inmediatos de la alta manipulación torácica de la temperatura superficial de la piel en la región vertebral en mujeres sanas. Para eso, se ha realizado un estudio clínico aleatorizado ciego en la comunidad universitaria. Veintiséis voluntarias han sido puestas de forma aleatorizada en un grupo experimental (n=13) y un grupo placebo (n=13). Ha sido realizada una sesión de manipulación torácica alta (segmento T3). Se ha empleado el término infrarrojo para determinar alteraciones en la temperatura de la piel en la región vertebral. Se han capturado imágenes antes, inmediatamente después, cinco y diez minutos tras la manipulación. Se ha hecho un análisis de los cambios con medidas repetidas (dos criterios) seguido de la prueba de Bonferroni para las comparaciones inter e intragrupal. Se ha adoptado un nivel de significancia de 5%. No ha sido encontrado diferencias significativas en las diferentes evaluaciones al largo del tiempo (p>0,05). En el análisis intergrupal, no ha sido constatado diferencias significativas en las comparaciones realizadas (p>0,05). Basándose en la metodología empleada, la manipulación torácica del segmento vertebral T3 no cambió la temperatura superficial de la piel en la región estudiada.

RESUMEN

AIM: The purpose of the present study was to correlate the degree of temporomandibular disorder (TMD) severity and skin temperatures over the temporomandibular joint (TMJ) and masseter and anterior temporalis muscles. MATERIALS AND METHODS: This blind cross-sectional study involved 60 women aged 18-40 years. The volunteers were allocated to groups based on Fonseca anamnestic index (FAI) score: no TMD, mild TMD, moderate TMD, and severe TMD (n = 15 each). All volunteers underwent infrared thermography for the determination of skin temperatures over the TMJ, masseter and anterior temporalis muscles. The Shapiro-Wilk test was used to determine the normality of the data. The Kruskal-Wallis test, followed by Dunn's test, was used for comparisons among groups according to TMD severity. Spearman's correlation coefficients were calculated to determine the strength of associations among variables. RESULTS: Weak, positive, significant associations were found between FAI score and skin temperatures over the left TMJ (rs = 0.195, p = 0.009) and right TMJ (rs = 0.238, p = 0.001). Temperatures over the right and left TMJ were significantly higher in groups with more severe TMD (p < 0.05). CONCLUSION: FAI score was associated with skin temperature over the TMJ, as determined by infrared thermography, in this sample. Women with more severe TMD demonstrated a bilateral increase in skin temperature.

RESUMEN

The aim of the present study was to investigate the correlation between the chronicity of myogenous temporomandibular disorder (TMD) and skin temperature over the masseter and anterior temporalis muscles. A blind, cross-sectional study was carried out involving 30 women with myogenous TMD, aged 18-40 years (mean of 23.60 ± 5.12 years). The volunteers were recruited from the university community. The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) was used for the diagnosis of TMD and the determination of chronicity. The volunteers were also submitted to infrared thermography to measure absolute skin temperature over the masseter and anterior temporalis muscles and determine their temperature asymmetries. A significant association was found between duration of TMD and temperature asymmetry of the anterior temporalis muscle (rs = 0.224, p = 0.034). The present findings demonstrate that chronicity of myogenous TMD changes the skin temperature over the anterior temporalis muscle.

RESUMEN

BACKGROUND AND OBJECTIVE: There is a close interaction between the mandibular and cervical systems due to the existing neurological and biomechanical communications. This study aimed to evaluate the relationship between neck disability and mandibular range of motion (ROM). MATERIALS AND METHODS: Fifty-two women aged between 18 and 40 years were recruited and allocated to four groups using two outcome measures: the Neck Disability Index (NDI) and the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD): Group I (n=13), healthy volunteers; Group II (n=13), volunteers with TMD and neck disability; Group III (n=13), volunteers with TMD and without neck disability; and Group IV (n=13), volunteers with neck disability and without TMD. Mandibular ROM was evaluated as part of the RDC/TMD clinical examination. Statistical analysis involved one-way ANOVA followed by Tukey's test for comparisons between groups. Spearman's correlation coefficients were calculated to determined correlations among the variables. RESULTS: Significant differences were found in the mandibular ROM of functional opening in the comparisons between Groups I and III (p=0.009) and between Groups III and IV (p=0.024). No significant association was found between mandibular ROM and the NDI score (p > 0.05). CONCLUSION: Based on the methodology employed, there is no association between mandibular ROM and neck disability in university women. In this sense, clinical interventions focusing on the flexibility of the temporomandibular joint does not have repercussions on the neck disability and vice versa.

RESUMEN

The aim of the present study was to assess the accuracy of two forms of infrared image analysis (area and extension) of the masseter and anterior temporalis muscles in the diagnosis of myogenous temporomandibular disorder (TMD). A cross-sectional study was carried out involving 104 female volunteers from the university community. Following the application of the Research Diagnostic Criteria for Temporomandibular Disorders, the volunteers were divided into a TMD group (n = 52) and control group (n = 52), and evaluated using infrared thermography. The area and extension of the masseter and anterior temporalis muscles were measured on the images. The receiver operating characteristic (ROC) curve was used to determine diagnostic accuracy (area under the curve), best cutoff point, sensitivity and specificity. A significant difference in skin temperature between groups was only found in the measurement of the area of the left anterior temporalis muscle (p = 0.011). The area under the ROC curve was less than the reference values for all muscles evaluated in the analyses of area and extension. Thus, neither method of infrared thermography tested for the quantification of the masseter and anterior temporalis muscles (analysis of area and extension) is consistent with the RDC/TMD for the diagnosis of myogenous TMD in women.

RESUMEN

OBJECTIVE: To evaluate the accidents with biological material among medical students interning in a trauma emergency room and identify key related situations, attributed causes and prevention. METHODS: we conducted a study with a quantitative approach. Data were collected through a questionnaire applied via internet, with closed, multiple-choice questions regarding accidents with biological material. The sample comprised 100 students. RESULTS: thirty-two had accidents with biological material. Higher-risk activities were local anesthesia (39.47%), suture (18.42%) and needle recapping (15.79%). The main routes of exposure to biological material were the eyes or mucosa, with 34%, and syringe needle puncture, with 45%. After contamination, only 52% reported the accident to the responsible department. CONCLUSION: The main causes of accidents and routes of exposure found may be attributed to several factors, such as lack of training and failure to use personal protective equipment. Educational and preventive actions are extremely important to reduce the incidence of accidents with biological materials and improve the conduct of post-exposure. It is important to understand the main causes attributed and situations related, so as general and effective measures can be applied.
