Abstract There is an increasing interest in essential oils extracted from Verbenaceae plant species as potential sources of biologically active compounds that could provide a starting point for designing novel phyto-pharmaceuticals in aquaculture. The present study was aimed to investigate the chemical composition, antioxidant activity, acute toxicity and antimicrobial effects against Vibrio parahaemolyticus of essential oils extracted from Lippia alba and L. origanoides. Approximately 23 components were identified and quantified by gas chromatography-mass spectrometry and flame ionization detection in each species’ essential oil. The most predominant compounds were geranial (23.0%), limonene (17.0%) and neral (15.5%) in L. alba, and thymol (47.2%), p-cymene (16.0%) and E-caryophyllene (11.3%) in L. origanoides. The essential oils have antibacterial activity against Vibrio parahaemolyticus presenting Minimum Inhibitory Concentration (MIC) and Bactericidal Concentration (MBC) values between 156-625 µg mL-1. The essential oils also show antioxidant potential estimated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assays, presenting IC50 of 60.16 mg mL-1 and 0.22 mg mL-1 for L. alba and L. origanoides EO, respectively. Both oils were classified as toxic to Artemia salina nauplii. Therefore, these essential oils may be useful for controlling pathogenic bacteria important to the aquaculture industry.

Abstract Background Management delays imply worse outcomes in rheumatoid arthritis (RA) and, therefore, should be minimized. We evaluated changes in diagnostic and treatment delays regarding RA in the last decades in Brazil. Methods Adults fulfilling the ACR/EULAR (2010) criteria for RA were assessed. Delays in diagnosis and treatment, and the frequencies of early management initiation within thresholds (windows of opportunity) of 3, 6, and 12 months from symptoms onset were evaluated. The Mann–Kendall trend test, chi-squared tests with Cramer’s V effect sizes and analysis of variance were conducted. Results We included 1116 patients: 89.4% female, 56.8% white, mean (SD) age 57.1 (11.5) years. A downward trend was found in diagnostic (tau = - 0.677, p < 0.001) and treatment (tau = - 0.695, p < 0.001) delays from 1990 to 2015. The frequency of early management increased throughout the period, with ascending effect sizes across the 3-, 6-, and 12-month windows (V = 0.120, 0.200 and 0.261, respectively). Despite all improvements, even in recent years (2011–2015) the diagnostic and treatment delays still remained unacceptably high [median (IQR): 8 (4–12) and 11 (5–17) months, respectively], with only 17.2% of the patients treated within the shortest, 3-month window. Conclusion The delays in diagnosis and treatment of RA decreased during the last decades in Brazil. Improvements (effect sizes) were greater at eliminating extreme delays (≥ 12 months) than in attaining really short management windows (≤ 3 months). Very early treatment was still an unrealistic goal for most patients with RA.

Abstract Background Early rheumatoid arthritis (RA) offers an opportunity for better treatment outcomes. In real-life settings, grasping this opportunity might depend on access to specialized care. We evaluated the effects of early versus late assessment by the rheumatologist on the diagnosis, treatment initiation and long-term outcomes of RA under real-life conditions. Methods Adults meeting the ACR/EULAR (2010) or ARA (1987) criteria for RA were included. Structured interviews were conducted. The specialized assessment was deemed “early” when the rheumatologist was the first or second physician consulted after symptoms onset, and “late” when performed afterwards. Delays in RA diagnosis and treatment were inquired. Disease activity (DAS28-CRP) and physical function (HAQ-DI) were evaluated. Student's t, Mann-Whitney U, chi-squared and correlation tests, and multiple linear regression were performed. For sensitivity analysis, a propensity score-matched subsample of early- vs. late-assessed participants was derived based on logistic regression. The study received ethical approval; all participants signed informed consent. Results We included 1057 participants (89.4% female, 56.5% white); mean (SD) age: 56.9 (11.5) years; disease duration: 173.1 (114.5) months. Median (IQR) delays from symptoms onset to both RA diagnosis and initial treatment coincided: 12 (6–36) months, with no significant delay between diagnosis and treatment. Most participants (64.6%) first sought a general practitioner. Notwithstanding, 80.7% had the diagnosis established only by the rheumatologist. Only a minority (28.7%) attained early RA treatment (≤ 6 months of symptoms). Diagnostic and treatment delays were strongly correlated (rho 0.816; p < 0.001). The chances of missing early treatment more than doubled when the assessment by the rheumatologist was belated (OR 2.77; 95% CI: 1.93, 3.97). After long disease duration, late-assessed participants still presented lower chances of remission/low disease activity (OR 0.74; 95% CI: 0.55, 0.99), while the early-assessed ones showed better DAS28-CRP and HAQ-DI scores (difference in means [95% CI]: −0.25 [−0.46, −0.04] and − 0.196 [−0.306, −0.087] respectively). The results in the propensity-score matched subsample confirmed those observed in the original (whole) sample. Conclusions Early diagnosis and treatment initiation in patients with RA was critically dependent on early access to the rheumatologist; late specialized assessment was associated with worse long-term clinical outcomes.

RESUMEN Objetivo. Evaluar si la calidad del calostro se modifica por las características genéticas, fisiológicas y de manejo en el período preparto, así como evaluar si la calidad y composición del calostro se alteran en el proceso de congelación. Material y métodos. En el experimento I, se recogieron muestras de calostro y sangre de 35 vacas (18 Holstein y 17 Jersey). En el experimento II, se recolectaron seis muestras de calostro de vacas Holstein y se congelaron durante 60 días. Resultados. La concentración media de inmunoglobulina G (IgG) fue de 77.65 mg/ml en Jersey y de 82.77 mg/ml en Holstein. La genética, el orden de parto y la interacción entre estos factores no fueron significativos en la concentración de IgG en el calostro. Además, se observó un efecto genético de la vaca en el peso en la cría al nacer y en los tres días de edad (p<0.0001). Con respecto a la transmisión de inmunidad pasiva de terneros, no se observaron efectos de la raza de la vaca y el orden de parto en la concentración de proteínas plasmáticas de la ternera, así como después de tres días de congelación. Las razas de becerros Holstein (83%) y Jersey (82%) mostraron niveles de proteína sérica total por encima de 5.5 g/dL. Las vacas Holstein alojadas en potreros individuales con suplementos dietéticos, proporcionaron una mejor calidad de calostro (93.57 mg IgG/mL). Con el tiempo, el porcentaje de grasa cambió al congelarse, que se redujo con el tiempo (p<0.05) en el Experimento II. Conclusiones. El manejo previo al parto influye en la calidad del calostro, y la congelación no interfiere en la calidad centesimal e inmunológica del calostro, con excepción de la grasa, que disminuye a lo largo del tiempo.
ABSTRACT Objective. The aims of this study were to assess whether colostrum quality is modified by genetic, physiological and management characteristics in the pre-partum period, as well as evaluate whether quality and composition of colostrum is altered in the freezing process. Material and methods. In the experiment I, colostrum and blood samples of 35 cows (18 Holstein and 17 Jerseys) were collected. In the experiment II, six colostrum samples of Holstein cows were collected and frozen during 60 days. Results. The mean immunoglobulin (Ig) concentration was 77.65 mg/ml to Jersey and 82.77 mg/ml to Holstein. The genetic, parturition order, and the interaction between these factors were no significant on IgG concentration in the colostrum. Also, it was observed an effect genetic of cow in the weight on calf at birth and on three days of age (p<0.0001). Regarding transmission of calf passive immunity, no effects of cow breed and calving order were observed on plasma protein concentration of calf, as well as after three days of freezing. Calves of Holstein (83%) and Jersey (82%) breed showed total serum protein levels above 5.5 g/dL. Holstein cows housed in individual paddocks with diet supplementation provided better quality of colostrum (93.57 mg Ig/mL). Over time, the percentage of fat reduced at freezing, that reduced over time (p<0.05) in Experiment II. Conclusions. The pre-partum management exerts influence on colostrum quality, and the freezing not interfere on centesimal and immunological quality of colostrum, with exception the fat, that decrease along the time.

Resumo Introdução: A cirurgia para a implantação do dispositivo interno do implante coclear não é inteiramente livre de riscos e pode apresentar problemas que exigem cirurgias revisionais. Objetivo: Verificar a incidência das indicações de cirurgias revisionais para a implantação do dispositivo interno do implante coclear, sua efetividade e correlacionar às variáveis relacionadas às categorias de linguagem e audição. Método: Estudo retrospectivo de pacientes menores de 18 anos submetidos à cirurgia de implante coclear de 2004 a 2015 em um hospital público no Brasil. Os dados coletados foram: idade no momento da implantação, sexo, etiologia da surdez, características audiológicas e da linguagem oral de cada paciente no pré e pós-operatório, necessidade de revisão cirúrgica e razão para ela. Resultados: Foram feitas 265 cirurgias em 236 pacientes. Oito pacientes foram submetidos ao implante coclear bilateral e 10 necessitaram de cirurgia de revisão. Foram necessárias 32 cirurgias para essas 10 crianças (um implante coclear bilateral), das quais 21 foram cirurgias de revisão. Em duas crianças, a remoção do implante coclear foi necessária, sem realização de reimplante; uma delas apresentava malformação coclear, por partição incompleta tipo I; e a outra, devido a trauma. Quanto à causa da necessidade da cirurgia revisional, das oito crianças que permaneceram com implante coclear, quatro apresentaram calcificação coclear após meningite, seguida de trauma (1), malformação do nervo facial (1), falha do dispositivo interno da IC (1) e torção do feixe de eletrodos (1). Conclusão: A incidência de cirurgias revisionais foi de 4,23%. O pós-operatório das cirurgias revisionais permite uma melhoria no desempenho de audição e na linguagem dos pacientes, indicando que essas cirurgias são válidas na maioria dos casos.
Abstract Introduction: The surgery during which the cochlear implant internal device is implanted is not entirely free of risks and may produce problems that will require revision surgeries. Objective: To verify the indications for cochlear implantation revision surgery for the cochlear implant internal device, its effectiveness and its correlation with certain variables related to language and hearing. Methods: A retrospective study of patients under 18 years submitted to cochlear implant surgery from 2004 to 2015 in a public hospital in Brazil. Data collected were: age at the time of implantation, gender, etiology of the hearing loss, audiological and oral language characteristics of each patient before and after cochlear implant surgery and any need for surgical revision and the reason for it. Results: Two hundred and sixty-five surgeries were performed in 236 patients. Eight patients received a bilateral cochlear implant and 10 patients required revision surgery. Thirty-two surgeries were necessary for these 10 children (1 bilateral cochlear implant), of which 21 were revision surgeries. In 2 children, cochlear implant removal was necessary, without reimplantation, one with cochlear malformation due to incomplete partition type I and another due to trauma. With respect to the cause for revision surgery, of the 8 children who were successfully reimplanted, four had cochlear calcification following meningitis, one followed trauma, one exhibited a facial nerve malformation, one experienced a failure of the cochlear implant internal device and one revision surgery was necessary because the electrode was twisted. Conclusion: The incidence of the cochlear implant revision surgery was 4.23%. The period following the revision surgeries revealed an improvement in the subject's hearing and language performance, indicating that these surgeries are valid in most cases.

Abstract Objective To assess the impact of the distance education course “Sickle Cell Disease: Primary Health Care Line” on knowledge acquisition of professional healthcare providers. Methods A cross-sectional study was conducted with a quantitative approach at the Educational and Support Center for Hemoglobinopathies (Cehmob-MG), state of Minas Gerais, Brazil, in 2016. One hundred and fifty-three out of 300 professional healthcare providers were invited to participate in the proposed distance course. Of the participating professional healthcare providers, 72 (47%) successfully concluded the course (Group A), whereas 81 (53%) did not complete their course assignments and did not meet the minimum requirements for regular attendance (Group B). Knowledge acquisition was assessed with the Knowledge of Sickle Cell Disease Instrument, DFConhecimento, applied using the web tool eSurv. Univariate analysis by Poisson regression was employed to assess the influence of sociodemographic variables on the DFConhecimento score and to select variables to compose the initial multivariate regression model (p-value < 0.20). The analysis was performed in the statistical programming environment R. Results The average score was 9.76 for Group A and 6.54 for Group B. The two groups were considered statistically different (p-value < 0.05) for all items with the proportion of correct items being greater in Group A. Professional healthcare providers who concluded the course had a significantly higher DFConhecimento score (45%) when compared to those who did not successfully conclude the course. Conclusion Participation in a distance education course on sickle cell disease had a positive impact on the acquisition of knowledge about the disease by professional healthcare providers.

RESUMO: Este estudo teve como objetivo analisar os casos de mastocitomas cutâneos em cães atendidos no Hospital Veterinário Governador Laudo Natel da Faculdade de Ciências Agrárias e Veterinárias (FCAV) Unesp Câmpus Jaboticabal, no período de 2005 a 2015, além de avaliar a ocorrência dessa neoplasia em relação à raça, sexo e idade; determinar as regiões corpóreas mais acometidas e as características neoplásicas observadas, assim como, os métodos de diagnóstico mais utilizados no setor, estabelecer os principais graus histológicos diagnosticados e os tratamentos preconizados, verificar alterações de tamanho em relação aos linfonodos, à taxa de recidiva, metástase e possíveis associações entre as variáveis consideradas. Foram avaliados 192 prontuários clínicos de pacientes e observou-se que os cães sem raça definida (SRD) (n=46, 23,96%) foram os mais acometidos, seguidos por cães da raça Boxer (n=40, 20,83%) e Pit bull (n=27, 14,06%). A maioria dos cães eram fêmeas (n=107, 55,7%), e com idade de 7 a 11 anos (n=120, 62,5%). Do total, 32 pacientes apresentaram (16,7%) tumores localizados em membro pélvico, seguidos por nódulos em membro torácico (10,4%, n=20). Sessenta e cinco animais possuíam nódulos ulcerados (33,9%), sendo 96 nódulos de consistência firme (50%). Setenta e seis animais apresentavam múltiplos nódulos (39,6%) e aqueles acima de três centímetros perfaziam 39,1% da amostra (n=75). O método mais utilizado para o diagnóstico foi a punção aspirativa por agulha fina associado à histopatologia (HT), totalizando 39,8% dos nódulos (n=66), seguido pela HT com 37,3% (n=62). Em relação às variáveis histológicas, 18 pacientes apresentaram grau I (11,8%), 112 com grau II (73,7%) e 22 com grau III (14,5%) de acordo com Patnaik et al. (1984). Segundo a classificação de Kiupel et al. (2011), 37 casos foram classificados como de alto grau (35,2%) e 68 como sendo de baixo grau (64,8%). Foi observada associação estatística quando se avaliou a presença de nódulos solitários/múltiplos e o grau histológico, segundo Patnaik et al. (1984) (p=0,008) e Kiupel et al. (2011) (p=0,004), sendo que nódulos com piores características prognósticas eram mais frequentes nos animais diagnosticados com múltiplos nódulos, independente da classificação histológica empregada. Também foi observada a associação entre a presença de nódulos múltiplos com estadio II ou IV (p<0,001) e com a presença de recidiva (p=0,001). Em relação à classificação histológica de Kiupel et al. (2011) foi possível observar associação estatística entre o grau histológico e o tamanho do tumor (p=0,001), a consistência (p=0,028) e a velocidade de crescimento do nódulo (p<0,001); aumento de linfonodo (p<0,001) e o tratamento empregado (p=0,002). Nódulos com tamanho superior a três centímetros (56,8%, n=21) e de crescimento rápido (52,9%, n=36%), eram mais frequentes nos tumores de alto grau. Aumento de linfonodo (80,6%, n=25) e tratamento quimioterápico (83,3%, n=5) também estavam associados a pacientes com alto grau histológico. Em relação à classificação de Patnaik et al. (1984), as variáveis raça e sexo diferiram proporcionalmente entre os grupos histológicos (p=0,008 e 0,040 respectivamente), sendo que o aumento do linfonodo e o crescimento rápido do tumor também tiveram associação com o grau histológico (p=0,002 e 0,001). Quase a metade dos pacientes (47,4%) foi submetidas ao tratamento cirúrgico e quimioterápico (n=91), sendo que em 31,3% (n=60) dos pacientes realizou-se apenas o procedimento cirúrgico. Sessenta e um animais (31,8%) apresentaram aumento de tamanho em linfonodos regionais (31,8%), sendo que 71,9% dos nódulos avaliados tiveram crescimento rápido. O tempo de evolução clínica do tumor foi menor ou igual a um ano, em 158 pacientes (82,3%), seguido por 25 pacientes (13%) com evolução de 1 a 2 anos. Foram observados 66 casos (40,5%) de recidiva e 16 (8,3%) de metástase à distância. Com este estudo, pode-se concluir que cães sem raça definida são os mais acometidos pelo mastocitoma cutâneo, na região de Jaboticabal, seguido por cães da raça Boxer, com idade variando entre 7 e 11 anos, não sendo observada predileção sexual; os nódulos encontrados eram predominantemente não ulcerados, solitários e menores que três centímetros; a maioria dos pacientes apresentou mastocitoma grau II, segundo Patnaik et al. (1984) e baixo grau segundo Kiupel et al. (2011); não se observou recidiva, em sua maioria, nem metástase em linfonodos e/ou a distância; o diagnóstico mais utilizado foi a punção aspirativa por agulha fina associada à histopatologia; a localização dos nódulos era mais prevalente nos membros pélvicos e torácicos, seguido por cabeça e pescoço. A consistência dos nódulos era de apresentação firme ou macia; e a metade dos pacientes foi submetida ao procedimento cirúrgico associado à quimioterapia antineoplásica.
ABSTRACT: This study analyzed the cases of cutaneous mastocytomas in dogs seen at the Governador Laudo Natel Veterinary Hospital of the College of Agrarian and Veterinary Sciences (FCAV), Unesp, in Jaboticabal, from 2005 to 2015. The objective was to determine the occurrence of this neoplasm regarding breed, sex, and age, the most affected body parts and observed neoplastic characteristics; the most widely used diagnosis methods, the main histological grades and recommended treatments, to evaluate size changes in relation to lymph nodes, recurrence rate, metastasis and to verify possible associations between the evaluated variables. The clinical files of 192 patients were evaluated. The most affected dogs were of mixed breed (n=46, 23.96%), followed by Boxer (n=40, 20.83%) and Pitbull (n=27, 14.06%). Most of the dogs were females (n=107, 55.7%), aged between 7 and 11 years old (n=120, 62.5%). Thirty-two patients had (16.7%) tumors located in the pelvic limb, followed by thoracic limbs (10.4% n=20). Sixty-five animals had ulcerated nodules (33.9%), of which 96 had firm consistency (50%). Seventy-six animals had multiple nodules (39.6%), and 39.1% of the sample (n=75) had nodules larger than three centimeters. The most used diagnosis method was fine needle aspiration together with histopathology (HT), totaling 39.8% of nodules (n=66), followed by HT in 37.3% of the patients (n=62). Regarding the histological variables, 18 patients had grade I (11.8%), 112 grade II (73.7%), and 22 grade III (14.5%) classified according to Patnaik et al. (1984). According to the classification of Kiupel et al. (2011) 37 cases were classified as high grade (35.2%) and 68 as low grade (64.8%). Statistical association was observed when the presence of solitary/multiple nodules and the histological grade were evaluated according to Patnaik et al. (1984) (P=0.008) and Kiupel et al. (2011) (P=0.004). The nodules with worse prognostic feature were more frequent in animals diagnosed with multiple nodules, regardless of the histological classification used. The presence of multiple nodules in stage II or IV (p<0.001) and recurrence of the disease (p=0.001) was also observed. Regarding the histological classification of Kiupel et al. (2011), there was a statistical association between histological grade and tumor size (p=0.001), consistency (p=0.028) and nodule growth rate (p<0.001), lymph node enlargement (p<0.001) and the treatment used (p=0.002). Nodules larger than three centimeters (56.8% n=21) and fast growing (52.9% n=36%) were more frequent in high-grade tumors. Lymph node enlargement (80.6% n=25) and chemotherapeutic treatment (83.3% n=5) were also associated with patients with this histological grade. According to the classification of Patnaik et al. (1984), breed and sex differed proportionally between the histological groups (p=0.008 and 0.040 respectively), and lymph node enlargement and rapid tumor growth were also associated with histological grade (p=0.002 and 0.001). Almost half of the patients (47.4%) underwent surgical and chemotherapeutic treatment (n=91) while only surgical procedure was performed in 31.3% (n=60) of the patients. Sixty-one animals (31.8%) had enlarged regional lymph nodes (31.8%), and 71.9% of the nodes evaluated had rapid growth. The clinical evolution time of the tumor was less than or equal to one year in 158 patients (82.3%), followed by 1 to 2 years in 25 patients (13%). There were 66 cases (40.5%) of recurrence and 16 (8.3%) of distant metastasis. With this study, it can be concluded that dogs with mixed breed are the most affected by cutaneous mastocytoma in Jaboticabal city, followed by Boxer dogs, with ages varying between 7 and 11 years, with no sexual predisposition observed. It was also concluded that nodules were predominantly non-ulcerated, solitary and smaller than 3 centimeters, that the majority of patients presented grade II mastocytoma according to Patnaik et al. (1984) and low grade according to Kiupel et al. (2011), not being observed in most of them recurrence, lymph node or distance metastasis. The most commonly used diagnosis was fine-needle aspiration associated with histopathology, and in relation to location, nodules were found predominantly in pelvic and thoracic limbs, followed by head and neck. The consistency of the nodules was both firm and soft, and half of the patients underwent the associated surgical procedure of antineoplastic chemotherapy.

Resumo O objetivo do presente estudo foi avaliar a taxa de crescimento de Balantidium coli em três meios de cultura xênicos. Entre 2013 e 2015 foram estudados 10 isolados de B. coli obtidos de Cynomolgus macaques e 30 isolados de suínos. Um inóculo contendo 500 trofozoítos foi transferido para tubos contendo os meios LES, TYSGM-9 e Pavlova. Os cultivos foram avaliados com tempos de incubação de 24, 48, 72 e 96 horas. Na maioria das cepas analisadas não foi observado diferença significativa na taxa de crescimento comparando TYSGM-9 e Pavlova (Wilcoxon p>0,016). Em Pavlova, os trofozoítos apresentaram máximo de crescimento a 72 h com diferença significativa quando se comparou com os tempos de 24 h e 96 h (Wilcoxon <0,008). Em LES observou-se trofozoítos viáveis até 24 horas com diferença significativa (Friedman p<0,05 e Wilcoxon p<0,016), na quantidade de células parasitárias, quando comparado com Pavlova e TYSGM-9. Dessa forma, o meio LES mostrou-se ser menos adequado do que os outros, para a manutenção de B. coli. Apesar do resultado satisfatório em TYSGM-9, Pavlova foi considerado ideal para manutenção do protozoário, por garantir a viabilidade do parasito com subcultivos a cada três dias, além de apresentar menor custo.
Abstract The aim of the present study was to evaluate the growth rate of Balantidium coli in three xenic media cultures. Between 2013 and 2015, 10 B. coli isolates obtained from feces of Cynomolgus macaques, and 30 isolates from feces of pigs were studied. An inoculum of 500 trophozoites was transferred to tubes containing LES, TYSGM-9 and Pavlova media. These cultures were evaluated at incubation times of 24, 48, 72 and 96 hours. In most of strains analyzed wasn’t showed significant difference in the growth rate comparing TYSGM-9 and Pavlova media (Wilcoxon p>0.016). In Pavlova medium, the trophozoites showed a maximum growth at 72 hours with significant difference when compared with the times of 24 h and 96 h (Wilcoxon <0.008). In LES, viable trophozoites were observed until 24 hours, with a significant difference (Friedman p<0.05, Wilcoxon p<0.016) in the number of parasite cells compared with Pavlova and TYSGM-9 media cultures. Thus, LES medium seemed to be less adequate than the other media for maintenance of B. coli. Despite the satisfactory results in TYSGM-9, Pavlova medium was considered ideal for the maintenance of this protozoan strain, guaranteeing the viability of the parasite with subculture every three days, presenting lower costs.

Laparoscopic and vaginal routes are the preferable routes to consider when planning a hysterectomy. Laparoscopy brings advantages to vaginal route when there are concomitant adnexal masses, endometriosis, pelvic inflammatory disease or previous abdominal surgeries. However, the learning curve in laparoscopy is slower and the surgery itself is, consequently, very dependent on the surgeon's experience. In this article, the authors review the first 300 total laparoscopic hysterectomy (TLH) surgeries in a new Obstetric/Gynecology Department. A retrospective analysis to clinical files of patients submitted to TLH between January 2013 and February 2016. Data was divided in 2 groups: group A, corresponding to the first 150 HTL and group B, with the 150 subsequent HTL. The results showed 2 similar groups, with median ages of 51 years old, with 27 median corporeal mass index, with 41% of the patients having previous abdominal surgeries. The main surgical indication was anomalous uterine bleeding secondary to mioma/adenomyosis (53%), and 309 concomitant surgeries were performed during surgical time (the majority in the adnexal area, 84%). Globally the intra-operatory and post-operatory complications rate was 1% and 2.3%, respectively, and most occurred in group A. The conversion rate to laparotomy or vaginal assisted laparoscopic hysterectomy was low (2.3%), and was only verified in group A, with statistic significance (p-value - 0.024). The blood loss volume was also statiscally different between the 2 groups (p-value < 0.001), with less volume blood loss in group B. The average uterine weight was similar in the 2 groups, with 187 and 168 grams, and the average surgical time was 155 and 148 minutes, which included the concomitant surgeries. In conclusions, despite the small number of cases, our study seems to show a tendency towards decrease in complications rate, conversion rate and blood loss, probably due to increased experience of the surgeons

ABSTRACT Hog raising generates a large amount of residues that is commonly discarded into the soil as fertilizer even with environmental risks. In this context, the aim of this study was to assess the application effects of different doses of swine wastewater (SW) associated with mineral fertilization on the abundance and diversity of organisms of soil meso- and macrofauna in two soybean crops. Treatments consisted of four doses (0, 100, 200, and 300 m3 ha−1) of SW with or without mineral fertilization in two soybean crop, totaling 24 experimental units. Soil meso- and macrofauna were sampled using pitfall traps installed at each plot. Samples were sorted and the organisms were separated and identified. The highest abundances were found between groups of springtails and spider mites. Soil meso- and macrofauna differed between soybean crops influenced by soil physical and chemical parameters. Doses of swine wastewater between 0 and 300 m3 ha−1 and mineral fertilization do not have effects on ecological indices of soil meso- and macrofauna. However, periodic applications over time change soil physicochemical variables, which may lead to negative effects in the long term.

RESUMEN El linfoma representa la enfermedad linfoproliferativa más frecuente en gatos. Sin embargo, el linfoma cutáneo es una rara forma de linfoma extranodal. Recientemente, el linfoma cutáneo se reportó localizado en el tarso. Tanto clínica como histopatológicamente, esta forma difiere de la forma cutánea típica, y se denominó linfoma tarsal felino. Este estudio describe el caso de un gato, doméstico de pelo largo, 13 años de edad con una masa subcutánea, de 30 días de evolución en la región tarsal del miembro pélvico derecho. La histopatologia reveló neoplasia de células redondas, sugestiva de linfoma de células grandes. La inmunohistoquímica confirmó el diagnóstico de linfoma imunoblástico de células B. El tratamiento realizado fue lomustina y prednisolona con tiempo de sobrevida de 2,1 meses. La agresividad de este linfoma, refuerza la necesidad de estudios para entender su curso y mejorar protocolos terapéuticos que incrementen tanto la sobrevida como la calidad de vida para estos pacientes.
ABSTRACT Lymphoma is the most common lymphoproliferative disorder in cats. Cutaneous lymphoma, however, is a rare form of extranodal lymphoma. Recently, several cutaneous lymphomas at the tarsal region have been reported in cats. As it differs clinically and histopathologically from the common cutaneous lymphoma, it was denominated cutaneous tarsal lymphoma. The present study describes the case of a 13-year-old male domestic longhair cat that presented with a subcutaneous mass, of 30-days evolution, at the tarsal region of the right pelvic limb. Histopathology analysis showed malignant neoplasia of round cells, morphologically suggestive of large cell lymphoma. Immunohistochemistry confirmed the diagnosis of B-immunoblastic lymphoma. Patient was treated with lomustine, and prednisolone with an overall survival time of 2.1 months. The aggressiveness of this feline lymphoma reinforces the need for further studies to understand better the disease progression and to establish improved therapeutic protocols that can increase survival time and improve quality of life of these patients.

RESUMO Objetivo: Determinar a precisão intra e inter-observador na identificação dos pontos Sella (S), Násio (N), A e B. Também, verificar como a identificação dos pontos pode interferir nas medições angulares de SNA e SNB por ortodontistas e radiologistas odontológicos. Métodos: Vinte telerradiografias laterais digitais foram avaliadas por cinco ortodontistas e cinco radiologistas odontológicos. Diferenças de medidas lineares e angulares foram avaliadas. Resultados: Concordância intra e inter-observador foi avaliada e a reprodutibilidade intra e inter-observador dos componentes horizontais e verticais da identificação S marco (ICC: 0,75 / 0,90). Ortodontistas tenderam a produzir maior valor para SNA (-0.18º), enquanto que para o ângulo SNB houve tendência a dimininuição do valor (0.55º). Em geral, os valores obtidos para o ângulo SNA foram menores (radiologistas: -0.308º e ortodontistas: -0.092º) e SNB apresentados com valores maiores (radiologistas: -0.074º: 0.078º e ortodontistas). Concordância intra e inter-observador foi avaliada e a reprodutibilidade intra e inter-observador dos componentes horizontais e verticais da identificação S marco (ICC: 0,75 / 0,90). Ortodontistas tenderam a produzir maior valor para SNA (-0.18º), enquanto que para o ângulo SNB houve tendência a dimininuição do valor (0.55º). Em geral, os valores obtidos para o ângulo SNA foram menores (radiologistas: -0.308º e ortodontistas: -0.092º) e SNB apresentados com valores maiores (radiologistas: -0.074º: 0.078º e ortodontistas). Conclusão: A identificação do ponto Sella revelou uma melhor concordância entre os radiologistas odontológicos. Ortodontistas, no entanto, mostraram uma maior variabilidade na identificação do ponto S e, consequentemente, os ângulos SNA e SNB variaram significativamente. A identificação do ponto Sella revelou uma melhor concordância entre os radiologistas odontológicos. Ortodontistas, no entanto, mostraram uma maior variabilidade na identificação do ponto S e, consequentemente, os ângulos SNA e SNB variaram significativamente.
ABSTRACT Objective: To determine intra- and inter-observer precision in Sella (S), Nasion (N), point A and B identification. Additionally, to determine how it can interfere with angular measurements of SNA and SNB by orthodontists and dentomaxillofacial radiologists. Methods: Twenty digital lateral cephalometric radiographs were evaluated by five orthodontists and five dentomaxillofacial radiologists. Results: Differences in linear and angular measuremts were assessed. Intra- and inter-observer agreement was evaluated. Intra- and inter-observer reproducibility of the horizontal and vertical components of the S landmark identification (ICC: 0.75/0.90). Orthodontists tended to produce larger SNA (-0.18º), while SNB angle had a tendency to be smaller (0.55º). In general, SNA angle was smaller (DMFRs: -0.308º and orthodontists: -0.092º), and SNB presented with larger values (DMFR: 0.078º and orthodontists: -0.074º). Conclusion: Identification of the Sella landmark revealed a better agreement amongst dentomaxillofacial radiologists. Orthodontists, however, showed a larger variability in S identification and, consequently, the SNA and SNB angles drifted significantly.

Resumo: Lesões cutâneas crônicas afetam 15% dos pacientes diabéticos e humanos representam um risco 15 a 46 vezes maior de amputações de membros em comparação com as pessoas com a glicemia normal. Supõe-se que a metade destas amputações poderia ser evitada por meio do tratamento precoce das feridas cutâneas com, por exemplo, uma adequada terapia celular. Objetivos: Neste estudo, a ação do transplante autólogo de células estaminais mesenquimais (MSC) foi avaliada em comparação com o tratamento com plasma rico em plaquetas autólogo (PRP) na cicatrização de lesões cutâneas induzidas em camundongos diabéticos. Estes animais foram previamente tratados com estreptozotocina para induzir diabetes mellitus e feridas redondas de 1,5 cm de diâmetro foram criadas na região posterior. Os diâmetros dos ferimentos e tempo de cicatrização foram avaliados durante 30 dias e os resultados foram submetidos à análise de variância e média pelo teste de Tukey. Verificou-se que os animais tratados com MSC apresentam uma cicatrização mais acelerada da lesão cutânea que do que os animais tratados com PRP. No entanto, o tratamento com PRP apresentou melhores resultados do que apenas a assepsia das lesões diariamente com solução salina ou cobrindo-os com atadura semi-permeável. Além disso, a utilização de atadura semi-permeável mantidas as lesões cutâneas de camundongos diabéticos não interfere negativamente com a cicatrização, provou ser inofensiva para usar, mas manteve as lesões cutâneas hidratadas mais do que os expostos ao meio ambiente.
Abstract: Chronic cutaneous lesions affect 15% of diabetic human patients and represent a risk 15 to 46 times larger of limb amputations compared to people with normal glycemia. It is assumed that half of these amputations could be prevented by early treatment of wounds, for example, with proper cell therapy. Objectives: In this study, the action of the autologous transplant of mesenchymal stem-cells (MSC) was evaluated compared to the treatment with autologous platelet rich plasma (PRP) in the cicatrization of cutaneous lesions induced in diabetic mice. These animals were previously treated with streptozootocin to induce diabetes mellitus and round wounds of 1.5cm in diameter were created in the posterior region. Diameters of the wounds and healing time were evaluated during 30 days and the results were submitted to variance analysis and Tukey's test average. It was noticed that the animals treated with MSC presented a more accelerated cicatrization of the cutaneous lesion than the animals treated with PRP. However, the treatment with PRP presented better results than just the daily asepsis of the lesions with saline or covering them with semi-permeable bandage. Besides, the use of semi-permeable bandage kept the cutaneous lesions of diabetic mice did not interfere negatively with cicatrization, proved to be harmless to use, but kept the cutaneous lesions more hydrated than the ones exposed to the environment.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.
