Abstract Objective Evaluate autonomic function and low-grade inflammation and characterize the correlation between these variables in schoolchildren with obesity living in the Brazilian northeast region. Methods 84 children with obesity and 41 with normal weight were included in this cross-sectional study. Anthropometry, body composition, blood pressure (BP), inflammatory biomarkers, and heart rate variability (HRV) indexes were analyzed in children aged 7 to 11 years. Results children with obesity had increased systolic (p= 0.0017) and diastolic (p= 0.0131) BP and heart rate (p= 0.0022). The children with obesity displayed significantly lower SDNN, RMSSD, NN50, HF (ms), HF (nu), SD1, SD2, and higher LF (ms), LF (nu), LF/HF, SD1/SD2, DFA-α1, and DFA-α2, compared to normal weight. A lower and higher capacity for producing IL-10 (p= 0.039) and IL-2 (p= 0.009), respectively, were found in children with obesity compared to children with normal weight. Although IL-2, IL-4 and IL17A did not correlate with HRV parameters, IL-6 was positively correlated with SDNN, LF (ms) and SD2, TNF-α was positively correlated with LF/HF and SD1/SD2 ratio, and IFN-γ was positively correlated with SDNN, RMMSSD, NN50, LF (ms), HF (ms), SD1, and SD2. Conclusions The findings suggest that children with obesity have impaired autonomic function and systemic low-grade inflammation compared to children within the normal weight range, the inflammatory biomarkers were correlated with HRV parameters in schoolchildren living in the northeastern region of Brazil.

ABSTRACT: The research was conducted to test the hypothesis that the inclusion of coffee husk (Coffea sp.) would improve the fermentative characteristics and quality of pearl millet silage (Pennisetumglaucum). Thus, the objective was to assess the effect of the inclusion of different levels of coffee husk in pearl millet silage on the chemical composition, fermentative characteristics and degradability in situ of silage. The experimental design used was completely randomized and the treatments consisted of the silage of the whole pearl millet plant with the inclusion of increasing levels of coffee husk: 0%, 7%, 14% and 21%, based on natural matter. After 60 days of fermentation, the silages were evaluated for chemical characteristics, fermentative, degradability in situ dry matter (DM) and neutral detergent fiber (NDF). The inclusion of coffee husk did not alter (P > 0.05) the contents of crude protein (11.94%), NDF (44.89%) and total digestible nutrients (65.09%). There were increases in the concentrations of DM and fiber in acid detergent, accompanied by a reduction in the concentrations of mineral matter and ether extract, as the proportion of coffee husks in silages increased. There was an increase in the lignin content up to the level of 7.59% inclusion of the coffee husk. There was no effect of the inclusion of the coffee husk on the pH of the silage (3.60). However, the inclusion of coffee husk resulted in a reduction in temperature, gas losses, and degradability in situ of silage DM and NDF. It is recommended to include coffee husk up to the level of 14.0% of the natural matter to improve the fermentation pattern and the quality of the pearl millet silage.

RESUMO: A pesquisa foi conduzida para testar a hipótese de que a inclusão de casca de café (Coffea sp.) melhoraria as características fermentativas e a qualidade da silagem de milheto (Pennisetum glaucum). Assim, objetivou-se avaliar o efeito da inclusão de diferentes níveis da casca de café na ensilagem de milheto sobre a composição química, características fermentativas e degradabilidade in situ da silagem. O delineamento experimental utilizado foi inteiramente casualizado e os tratamentos constituíram-se pela silagem da planta inteira de milheto com a inclusão de níveis crescentes de casca de café: 0%, 7%, 14% e 21%, com base na matéria natural. Após 60 dias de fermentação, as silagens foram avaliadas quanto às características químicas, fermentativas, degradabilidade in situ da matéria seca (MS) e da fibra em detergente neutro (FDN). A inclusão da casca de café não alterou (P > 0,05) os teores de proteína bruta (11,94%), FDN (44,89%) e nutrientes digestíveis totais (65,09%). Houve aumentos nas concentrações de MS e fibra em detergente ácido, acompanhados de uma redução nas concentrações de matéria mineral e extrato etéreo, à medida que se aumentou a participação da casca de café nas silagens. Houve um aumento no teor de lignina até o nível de 7,59% de inclusão da casca de café. Não houve efeito da inclusão da casca de café sobre o pH da silagem (3,60). Entretanto, a inclusão de casca de café acarretou na redução da temperatura, perdas por gases, degradabilidade in situ da MS e FDN da silagem. Recomenda-se a inclusão de casca de café até o nível de 14,0% da matéria natural para melhoria do padrão de fermentação e da qualidade da silagem de milheto.

RESUMO Objetivo: Inquérito nacional de cobertura vacinal aos 12 e 24 meses de idade foi realizado para investigar as quedas nas coberturas a partir de 2016. Métodos: Amostra de 37.836 nascidos vivos das coortes de 2017 e 2018 residentes nas capitais, Distrito Federal (DF) e 12 cidades com mais de 100 mil habitantes, acompanhados nos primeiros 24 meses por registros nas cadernetas de vacinação. Setores censitários foram estratificados segundo condições socioeconômicas, e o mesmo número de crianças foi incluído para cada estrato. Calcularem-se coberturas vacinais de cada vacina e coberturas completas aos 12 e 24 meses, doses aplicadas, válidas e oportunas. Fatores familiares, maternos e da criança associados à cobertura foram pesquisados. Os motivos para não vacinar analisados foram: contraindicações médicas, dificuldades de acesso, problemas no funcionamento do programa e hesitação vacinal. Resultados: Os resultados preliminares mostram que menos de 1% das crianças não foram vacinadas, as coberturas pelo esquema completo são menores que 75% em todas as capitais e no DF, as vacinas com mais de uma dose perdem cobertura progressivamente, há diferenças entre os estratos socioeconômicos, favoráveis aos estratos mais altos em algumas cidades e aos estratos mais baixos em outras. Conclusão: Houve realmente redução da cobertura vacinal em todas as capitais e no DF para as crianças nascidas em 2017 e 2018, denotando piora na execução do Programa Nacional de Imunizações durante os anos de 2017 a 2019. O inquérito realizado não mensurou os impactos da pandemia de COVID-19 que podem ter reduzido ainda mais as coberturas vacinais.

ABSTRACT Objective: The national vaccination coverage survey on full vaccination at 12 and 24 months of age was carried out to investigate drops in coverage as of 2016. Methods: A sample of 37,836 live births from the 2017 or 2018 cohorts living in capital cities, the Federal District, and 12 inner cities with 100 thousand inhabitants were followed for the first 24 months through vaccine record cards. Census tracts stratified according to socioeconomic levels had the same number of children included in each stratum. Coverage for each vaccine, full vaccination at 12 and 24 months and number of doses administered, valid and timely, were calculated. Family, maternal and child factors associated with coverage were surveyed. The reasons for not vaccinating analyzed were: medical contraindications, access difficulties, problems with the program, and vaccine hesitancy. Results: Preliminary results showed that less than 1% of children were not vaccinated, full coverage was less than 75% at all capitals and the Federal District, vaccines requiring more than one dose progressively lost coverage, and there were inequalities among socioeconomic strata, favorable to the highest level in some cities and to the lowest in others. Conclusion: There was an actual reduction in full vaccination in all capitals and the Federal District for children born in 2017 and 2018, showing a deteriorating implementation of the National Immunization Program from 2017 to 2019. The survey did not measure the impacts of the COVID-19 pandemic, which may have further reduced vaccination coverage.

ABSTRACT BACKGROUND: Gastric neuroendocrine tumors are a heterogeneous group of neoplasms that produce bioactive substances. Their treatment varies according to staging and classification, using endoscopic techniques, open surgery, chemotherapy, radiotherapy, and drugs analogous to somatostatin. AIMS: To identify and review cases of gastric neuroendocrine neoplasia submitted to surgical treatment. METHODS: Review of surgically treated patients from 1983 to 2018. RESULTS: Fifteen patients were included, predominantly female (73.33%), with a mean age of 55.93 years. The most common symptom was epigastric pain (93.3%), and the mean time of symptom onset was 10.07 months. The preoperative upper digestive endoscopy (UDE) indicated a predominance of cases with 0 to 1 lesion (60%), sizing ≥1.5 cm (40%), located in the gastric antrum (53.33%), with ulceration (60%), and Borrmann III (33.33%) classification. The assessment of the surgical specimen indicated a predominance of invasive neuroendocrine tumors (60%), with angiolymphatic invasion in most cases (80%). Immunohistochemistry for chromogranin A was positive in 60% of cases and for synaptophysin in 66.7%, with a predominant Ki-67 index between 0 and 2%. Metastasis was observed in 20% of patients. The surgical procedure most performed was subtotal gastrectomy with Roux-en-Y reconstruction (53.3%). Tumor recurrence occurred in 20% of cases and a new treatment was required in 26.67%. CONCLUSIONS: Gastric neuroendocrine tumors have a low incidence in the general population, and surgical treatment is indicated for advanced lesions. The study of its management gains importance in view of the specificities of each case and the need for adequate conduct to prevent recurrences and complications.

RESUMO RACIONAL: Os tumores neuroendócrinos gástricos são um grupo heterogêneo de neoplasias produtoras de substâncias bioativas, sendo o seu tratamento variável de acordo com o estadiamento e a classificação, sendo utilizadas técnicas endoscópicas, cirurgias abertas, quimioterapia, radioterapia e fármacos análogos da somatostatina. OBJETIVOS: Identificar e revisar os casos de neoplasia neuroendócrina gástrica submetidos a tratamento cirúrgico. MÉTODOS: Revisão os doentes tratados cirurgicamente de 1983 e 2018. RESULTADOS: Foram incluídos 15 pacientes, com predomínio do sexo feminino (73,33%) e média de idade de 55,93 anos. O sintoma mais comum foi a epigastralgia (93,3%) e o tempo médio do início dos sintomas foi de 10,07 meses. A endoscopia digestiva pré-operatória indicou predomínio de casos com 0 a 1 lesões (60%), de tamanho ≥ 1,5 cm (40%), localizadas em antro gástrico (53,33%), com ulceração (60%), Borrmann 3 (33,33%). A avaliação da peça cirúrgica indicou um predomínio de tumores neuroendócrinos invasivos (60%), com invasão angiolinfática na maioria dos casos (80%). A imuno-histoquímica para cromogranina A foi positiva em 60% dos casos e para sinaptofisina em 66,7%, com índice de Ki-67 predominante entre 0 e 2%. Metástases foram observadas em 20% dos casos. O procedimento cirúrgico mais utilizado foi a gastrectomia subtotal com reconstrução em Y de Roux (53,3%). Recidiva tumoral ocorreu em 20% dos casos e novo tratamento foi necessário em 26,67% dos casos. CONCLUSÕES: Os tumores neuroendócrinos gástricos apresentam baixa incidência na população em geral, e o tratamento cirúrgico está indicado nas lesões avançadas. O estudo de seu manejo ganha importância frente às especificidades de cada caso e a necessidade de conduta adequada para a prevenção de recidivas e complicações.

Abstract The present research aimed to demonstrate the feasibility of using image segmentation for better drainage extraction, automated drainage network hierarchization and main channel definition based on Horton (1945). The test area for the applications was the Bandeirinha Stream Hydrographic Basin (BSHB), which is located in the municipality of Formosa, in the state of Goiás, Brazil. The study used the Shuttle Radar Topography Mission (SRTM), with a spatial resolution of 1" x 1" (one arc second). The SRTM segmentation was performed using the Python language ODR_Obia algorithm, inserted with a QGIS plugin. Through the QGIS platform, the ODR_Hidro plugin was used to perform the delimitation of the BSHB, the extraction of the drainages and the definition of the main channel. The results were validated in the field and evaluated from the manual definition of the main channel. That was done using both the data produced by the application and the drainage data contained in the vector base of the topographic maps of the Army of Geographic Service (AGS), at the scale of 1:100,000 and 1:25,000. From the results obtained, it can be inferred that the ODR_Hidro model used for the delimitation of the BSHB, the automated hierarchization of the drainages and the definition of the main channel from the segmented SRTM image is very efficient. The field validation demonstrated its effectiveness by proving the existence of first-order drainages which are not mapped on the DSG chart at a scale of 1:100.000. This leads to the conclusion that the use of the proposed tools and the inclusion of image segmentation, aiming for the extraction of drainage network and geomorphometric characterization of watersheds, can efficiently contribute to the provision of morphometric data.

ABSTRACT Objective The incidence of thrombotic events and acute kidney injury is high in critically ill patients with COVID-19. We aimed to evaluate and compare the coagulation profiles of patients with COVID-19 developing acute kidney injury versus those who did not, during their intensive care unit stay. Methods Conventional coagulation and platelet function tests, fibrinolysis, endogenous inhibitors of coagulation tests, and rotational thromboelastometry were conducted on days 0, 1, 3, 7, and 14 following intensive care unit admission. Results Out of 30 patients included, 13 (43.4%) met the criteria for acute kidney injury. Comparing both groups, patients with acute kidney injury were older: 73 (60-84) versus 54 (47-64) years, p=0.027, and had a lower baseline glomerular filtration rate: 70 (51-81) versus 93 (83-106) mL/min/1.73m2, p=0.004. On day 1, D-dimer and fibrinogen levels were elevated but similar between groups: 1780 (1319-5517) versus 1794 (726-2324) ng/mL, p=0.145 and 608 (550-700) versus 642 (469-722) g/dL, p=0.95, respectively. Rotational thromboelastometry data were also similar between groups. However, antithrombin activity and protein C levels were lower in patients who developed acute kidney injury: 82 (75-92) versus 98 (90-116), p=0.028 and 70 (52-82) versus 88 (78-101) µ/mL, p=0.038, respectively. Mean protein C levels were lower in the group with acute kidney injury across multiple time points during their stay in the intensive care unit. Conclusion Critically ill patients experiencing acute kidney injury exhibited lower endogenous anticoagulant levels. Further studies are needed to understand the role of natural anticoagulants in the pathophysiology of acute kidney injury within this population.

RESUMO: Descrevem-se casos de periodontite em ovinos provenientes das regiões do Agreste e Zona da Mata de Pernambuco, Nordeste do Brasil. Informações sobre raça, idade e sexo dos animais afetados bem como os aspectos clínicos e patológicos dos surtos foram obtidos a partir de visitas às propriedades e são reportados. 15 animais de um total de 450 ovinos da raça Santa Inês, com idade entre três a doze anos de idade manifestaram baixa condição corporal, pelagem sem brilho e dificuldade de alimentar-se, acompanhado de dor à palpação na região mandibular. O exame físico da cavidade oral dos animais afetados e os achados post mortem de indivíduos abatidos revelaram graus variados de periodontite, desgaste, fratura, mobilidade e perda dentária, associados a retração gengival, presença de biofilme e compactação de resíduos alimentares entre os dentes incisivos, pré-molares e molares. Em oito animais havia aumento de volume mandibular e em dois deles observaram-se abscessos fistulados que ocorreram exclusivamente nos dentes mandibulares. A ocorrência de periodontite em ovinos não têm sido registrada no Nordeste do Brasil, sendo estes os primeiros casos descritos na região.

ABSTRACT: Cases of periodontitis in sheep from the Agreste and Zona da Mata regions of Pernambuco, Northeastern Brazil, are described. Information on breed, age and sex of affected animals as well as clinical and pathological aspects of the disease were obtained during farm visits. Fifteen animals from a total of 450 Santa Inês sheep, aged between three and twelve years, showed low body condition score, dull coat, and difficulty in feeding followed by pain on palpation of the mandibular region. Physical examination of the oral cavity of affected animals and post mortem findings of slaughtered individuals revealed varying degrees of periodontitis, wear, fracture, mobility, and loss of teeth associated with gingival retraction, presence of biofilm and food packing between incisors, premolars and molars teeth. Increased mandibular volume was observed in eight animals and, in two of them, an abscess fistula, exclusively in mandibular teeth. The occurrence of periodontitis in sheep had not been recorded until now in Northeastern Brazil and, thus, this is the first description of cases in the region.

Abstract Schistosomiasis is a neglected tropical disease and affects over 200 million people worldwide. The snail Biomphalaria glabrata is one of the intermediate hosts of S. mansoni. The aim of this work was to verify the action of Euphorbia milii var. hislopii latex in the hemocytes profile and histopathology of B. glabrata infected by S. mansoni. Uninfected and infected snails were exposed to sublethal concentration of E. milii latex for 24 hours (1.0 mg/L). The survival rate was 88.5% for the uninfected snails and 66.6% for the infected and exposed snails. In the snails infected by S. mansoni, the exposure to E. milii latex promoted proliferation of hemocytes in the tentacles, mantle, digestive gland and kidney. In the digestive gland and the kidney, granulomatous reactions occurred around the sporocysts and caused their destruction. The number of circulating hemocytes from the group infected and exposed to E. milii latex was significantly higher than in the other groups. Three types of hemocytes were found: hyalinocytes, granulocytes and blast-like cells. We conclude that the E. milii latex influenced the cellular immune response of the susceptible B. glabrata strain to infection by S. mansoni, promoting the destruction of parasites.

Abstract Banana tree bacterial wilt is caused by the Ralstonia solanacearum Moko ecotype. These strains vary in their symptom progression in banana, and are classified as typical Moko variants (phylotype IIA and IIB strains from across Central and South America), Bugtok variant (Philippines), and Sergipe facies (the states of Sergipe and Alagoas, Brazil). This study used comparative genomic and phylogenomic approaches to identify a correlation between the symptom progression of the Moko ecotypes based on the analysis of 23 available genomes. Average nucleotide identity and in silico DNA-DNA hybridization revealed a high correlation (>96% and >78%, respectively) between the genomes of Moko variants. Pan-genome analysis identified 21.3% of inheritable regions between representatives of the typical Moko and Sergipe facies variants, which could be traced to an abundance of exclusive homolog clusters. Moko ecotype genomes shared 1,951 orthologous genes, but representatives with typical symptoms did not display unique orthologues. Moreover, Bugtok disease and Sergipe facies genomes did not share any unique genes, suggesting convergent evolution to a shared symptom progression. Overall, genomic and phylogenomic analyses were insufficient to differentiate the Moko variants based on symptom progression.

RESUMO: Descrevem-se os aspectos clínicos, patológicos e reprodutivos de um surto de deficiência de cobre em cabras leiteiras e em cabritos da região semiárida de Pernambuco, Brasil. Dez cabras leiteiras adultas com sinais clínicos de deficiência de cobre e quatro cabritos com ataxia enzoótica nascidos dessas cabras foram separados do rebanho e examinados. Nas cabras leiteiras, a concentração média de cobre sérico foi de 6,1±2,8mmol/L e a concentração média de ferro sérico foi de 39,5±8,2mmol/L. Nos cabritos, a concentração média de cobre sérico foi de 3,8±0,9mmol/L e a concentração média de ferro sérico foi de 38,5±4,1mmol/L. Os sinais clínicos nas cabras consistiram em mucosas pálidas, anemia, diarreia, acromotriquia, pelos opacos e quebradiços e alopecia. As principais alterações reprodutivas consistiram em anestro prolongado, reabsorção embrionária e aumento da taxa de retenção de placenta. Os cabritos nascidos vivos dessas cabras nasceram fracos, com ataxia neonatal ou desenvolveram ataxia tardia em até 70 dias de vida. Seis cabras leiteiras e quatro cabritos foram necropsiados. Nas cabras, a maioria dos ovários examinados macroscopicamente eram pequenos, firmes e não apresentavam folículos viáveis em sua superfície. Microscopicamente, houve redução de folículos viáveis, além de desorganização das estruturas foliculares, com marcada atresia folicular. Macroscopicamente não foram observadas alterações nos cabritos com ataxia enzoótica. As lesões histológicas observadas nesses cabritos consistiram em cromatólise neuronal e degeneração axonal, principalmente em neurônios da medula espinhal. Neste estudo a fonte dos altos teores de ferro no soro não foi identificada, mas sabe-se que surtos de deficiência de cobre podem ocorrer devido ao excesso de ingestão de ferro, principalmente quando não é fornecida suplementação mineral adequada para os rebanhos caprinos.

ABSTRACT: The clinical, pathological and reproductive aspects of an outbreak of copper deficiency in dairy goats and kids from the semiarid region of Pernambuco, Brazil are described. Ten adult dairy goats with clinical signs of deficiency and four kids presenting enzootic ataxia born from copper deficient does were separated from the herd, and examined. In the dairy goats, the average serum concentration of copper was 6.1±2.8mmol/L and iron was 39.5±8.2mmol/L. In kids, the average serum concentration of copper was 3.8±0.9mmol/L and iron was 38.5±4.1mmol/L. Clinical signs in dairy goats consisted of pale mucous membranes, anemia, emaciation, diarrhea, achromotrichia, brittle hair and alopecia. The main reproductive alterations consisted of prolonged anestrus, embryonic resorption and high indices of retained placenta. The kids born from copper deficient dairy goats were weak, and presented neonatal or late ataxia until 70 days of life. Six dairy goats and four kids were necropsied. Most ovaries examined were small, firm and did not present viable follicles on their surface. Microscopically, there was reduction of viable follicles in addition to disorganization of follicular and stromal structures, with marked follicular atresia. Microscopically, changes in kids with enzootic ataxia consisted of neuronal chromatolysis and axonal degeneration, mainly in neurons of the spinal cord. In this study, the source of high iron was not identified, but it is known that outbreaks of copper deficiency can occur due to excess iron intake, mainly when adequate mineral supplementation is not provided for the goat herds.

ABSTRACT BACKGROUND: Caustic ingestion is still a health problem of utmost importance in the West. In developing countries, this incident remains at increase and it is associated with unfavorable factors like social, economic, and educational handicaps, besides a lack of prevention. Esophagocele is a rare consequence of caustic ingestion. AIM: We aimed to describe a patient with multiple caustic ingestions who presented an esophagocele resected by videothoracoscopy. METHODS: A woman ingested caustic soda when she was only 17 years old in a suicidal attempt during a depressive crisis. Initially, she was submitted to a retrosternal esophagocoloplasty with the maintenance of her damaged esophagus. After 1 year of this first surgery, she ingested caustic soda again in a new suicidal attempt. Her transposed large bowel in the first surgery became narrow, being replaced in a second surgery by a retrosternal esophagogastroplasty. Still, at the second surgery, her damaged esophagus remained in its original position in the posterior mediastinum. However, after 5 years, she developed an esophagocele. RESULTS: The esophagocele was resected through videothoracoscopy in a prone position, employing four trocars. The postoperative was uneventful. CONCLUSION: Esophageal exclusion must always be recorded because esophagocele presents unspecific symptoms. The videothoracoscopy in a prone position is an excellent technical option to resect esophagoceles.

RESUMO RACIONAL: A ingestão de produtos cáusticos ainda é um problema de saúde de extrema importância no Ocidente. Nos países em desenvolvimento, este incidente continua em ascensão e está associada a fatores desfavoráveis como sociais, econômicos e educacionais, além da falta de prevenção. A esofagocele é uma consequência rara da ingestão de cáusticos. OBJETIVO: Nosso objetivo é descrever um paciente com múltiplas ingestões cáusticas que apresentou uma esofagocele ressecada por videotoracoscopia. MÉTODOS: Doente feminina que ingeriu soda cáustica com 17 anos de idade, como tentativa de suicídio, durante uma crise depressiva. Inicialmente, foi submetida a esofagocoloplastia retroesternal com manutenção do esôfago lesado. Após um ano desta primeira cirurgia, voltou a ingerir soda cáustica, em nova tentativa de suicídio. Seu intestino grosso transposto na primeira cirurgia tornou-se estenosado, sendo substituído em uma segunda cirurgia, por esofagogastroplastia retroesternal. Ainda assim, nesta segunda cirurgia, o esôfago lesado permaneceu em sua posição original no mediastino posterior. No entanto, após cinco anos, ela desenvolveu uma esofagocele. RESULTADOS: A esofagocele foi ressecada por videotoracoscopia, em decúbito ventral, empregando-se quatro trocartes. O pós-operatório transcorreu sem intercorrências. CONCLUSÕES: A exclusão esofágica deve ser sempre registrada, pois a esofagocele apresenta sintomas inespecíficos. A videotoracoscopia em posição prona é uma excelente opção técnica para ressecção de esofagoceles.

Abstract Banana vascular wilt or Moko is a disease caused by Ralstonia solanacearum. This study aimed to sequence, assemble, annotate, and compare the genomes of R. solanacearum Moko ecotypes of different sequevar strains from Brazil. Average nucleotide identity analyses demonstrated a high correlation (> 96%) between the genome sequences of strains CCRMRs277 (sequevar IIA-24), CCRMRs287 (IIB-4), CCRMRs304 (IIA-24), and CCRMRsB7 (IIB-25), which were grouped into phylotypes IIA and IIB. The number of coding sequences present in chromosomes and megaplasmids varied from 3,070 to 3,521 and 1,669 to 1,750, respectively. Pangenome analysis identified 3,378 clusters in the chromosomes, of which 2,604 were shared by all four analyzed genomes and 2,580 were single copies. In megaplasmids, 1,834 clusters were identified, of which 1,005 were shared by all four genomes and 992 were identified as single copies. Strains CCRMRsB7 and CCRMRs287 differed from the others by having unique clusters in both their chromosomes and megaplasmids, and CCRMRsB7 possessed the largest genome among all Moko ecotype strains sequenced to date. Therefore, the genomic information obtained in this study provides a theoretical basis for the identification, characterization, and phylogenetic analysis of R. solanacearum Moko ecotypes.

RESUMO Racional: A terapia multimodal com quimioradioterapia neoadjuvantes, seguido de esofagectomia tem oferecido melhores resultados de sobrevida, em comparação à esofagectomia isolada, no câncer do esôfago avançado. Além disso, os doentes que apresentam resposta patológica completa ao tratamento neoadjuvante, têm evoluido com maior sobrevida global e maior sobrevida livre de doença em comparação aos que apresentam resposta incompleta. Objetivo: Comparar os resultados de sobrevida global e sobrevida livre de doença entre os doentes com resposta completa e incompleta, submetidos à quimioradioterapia neoadjuvante, com dois esquemas terapêuticos, seguidos de esofagectomia transhiatal. Métodos: Estudo retrospectivo, aprovado pelo Comitê de Ética em pesquisa, analisando os prontuários de 56 doentes, divididos em dois grupos de pacientes, submetidos a radioterapia (4400 a 5400 cGY) e quimioterapia (5-Fluorouracil+Cisplatina versus Paclitaxel+Carboplatina) neoadjuvantes e posteriormente a tratamento cirúrgico, no período de 2005 a 2012, portadores de carcinoma espinocelular do esôfago. Resultados: Os grupos não diferiram significativamente quanto ao gênero, raça, idade, complicações pós-operatórias, sobrevida livre de doença e sobrevida global. A sobrevida em 5 anos de doentes com resposta incompleta e completa foram, respectivamente, 18,92% e 42,10% (p>0,05). Entretanto, os doentes que receberam Paclitaxel+Carboplatina, tiveram melhores respostas patológicas completas à neoadjuvância, em comparação ao 5-Fluorouracil+Cisplatina (47,37% versus 21,62% - p=0,0473, p<0,05). Conclusões: Não houve diferença estatística na sobrevida global e na sobrevida livre de doença dos doentes que apresentaram resposta patológica completa à neoadjuvância. Os doentes submetidos ao esquema terapêutico com Paclitaxel e Carboplastina, mostraram diferença significativa com melhor resposta patológica completa e evolução da doença. Novos parâmetros são indicados para esclarecer o real valor na sobrevida, da resposta patológica completa à neoadjuvância, no câncer de esôfago.

ABSTRACT Background Multimodal therapy with neoadjuvant chemoradiotherapy, followed by esophagectomy has offered better survival results, compared to isolated esophagectomy, in advanced esophageal cancer. In addition, patients who have a complete pathological response to neoadjuvant treatment presented greater overall survival and longer disease-free survival compared to those with incomplete response. Aim: To compare the results of overall survival and disease-free survival among patients with complete and incomplete response, submitted to neoadjuvant chemoradiotherapy, with two therapeutic regimens, followed by transhiatal esophagectomy. Methods: Retrospective study, approved by the Research Ethics Committee, analyzing the medical records of 56 patients with squamous cell carcinoma of the esophagus, divided into two groups, submitted to radiotherapy (5040 cGY) and chemotherapy (5-Fluorouracil + Cisplatin versus Paclitaxel + Carboplatin) neoadjuvants and subsequently to surgical treatment, in the period from 2005 to 2012, patients. Results The groups did not differ significantly in terms of gender, race, age, postoperative complications, disease-free survival and overall survival. The 5-year survival rate of patients with incomplete and complete response was 18.92% and 42.10%, respectively (p> 0.05). However, patients who received Paclitaxel + Carboplatin, had better complete pathological responses to neoadjuvant, compared to 5-Fluorouracil + Cisplatin (47.37% versus 21.62% - p = 0.0473, p <0.05). Conclusions There was no statistical difference in overall survival and disease-free survival for patients who had a complete pathological response to neoadjuvant. Patients submitted to the therapeutic regimen with Paclitaxel and Carboplastin, showed a significant difference with better complete pathological response and disease progression. New parameters are indicated to clarify the real value in survival, from the complete pathological response to neoadjuvant, in esophageal cancer.

RESUMO: A mastite é uma doença multifatorial e é considerada um dos problemas mais importantes na indústria de laticínios no mundo todo. A condição é caracterizada pela redução de leite e várias anormalidades na glândula mamária. O objetivo deste estudo foi relatar um surto de mastite gangrenosa causada por Staphylococcus haemolyticus multirresistente em um rebanho ovino Santa Inês. Dezoito ovelhas foram afetadas e cinco delas com quadro clínico severo foram examinadas. O quadro clínico-patológico era variável quanto a severidade e consistia em apatia, anorexia, magreza, pelos opacos e quebradiços e vasos episclerais aparentes e ingurgitados. As ovelhas apresentavam glândulas aumentadas, firmes e dolorosas. Macroscopicamente, as principais lesões consistiam em mastite gangrenosa e microscopicamente havia necrose do parênquima glandular, trombose e fibrose. Amostras de leite de uma das cinco ovelhas severamente afetadas foram coletadas e cultivadas sob incubação aeróbica ou microaerofílica a 37°C por 24 horas em ágar sangue de ovelha. As colônias obtidas foram então submetidas ao MALDI-TOF para especiação. Além disso, as colônias foram submetidas a um teste de suscetibilidade antimicrobiana e foi realizada a genotipagem de fatores de virulência e genes de resistência. Os isolados apresentaram multirresistência antimicrobiana por serem resistentes a sete dos 13 antibióticos testados. Os isolados também foram positivos para dois genes enterotoxigênicos estafilocócicos (sec e see) e proteína B de ligação à fibronectina (fnbB).

ABSTRACT: Mastitis is a multifactorial disease and considered one of the most critical problems in the dairy industry worldwide. The condition is characterized by reduced milk and several abnormalities in the mammary gland. This study aimed to report an outbreak of gangrenous mastitis caused by multidrug-resistant Staphylococcus haemolyticus in a Santa Inês sheep herd. Eighteen sheep were affected, and five of them with severe clinical pictures were examined. The clinical and pathological picture were variable and characterized by apathy, anorexia, emaciation, opaque and brittle hair, apparent and congested episcleral vessels, and hyperthermia. These ewes had enlarged, firm, and painful mammary glands. Macroscopically, these lesions consisted of severe gangrenous mastitis, and microscopically, the primary lesions consisted of necrosis, thrombosis, and fibrosis of the mammary parenchyma. Milk samples from one of the five severely affected ewes were collected and cultured under aerobic or microaerophilic incubation at 37°C for 24 hours on sheep blood agar. The obtained colonies were then submitted to MALDI-TOF for speciation. The colonies were also submitted to an antimicrobial susceptibility test, genotyping of virulence factors and resistance genes were also performed. The isolates showed antimicrobial multiresistance since they were resistant to seven out of 13 tested antibiotics. The isolates were also positive for two staphylococcal enterotoxigenic genes (sec and see) and fibronectin-binding protein B (fnbB).
