ABSTRACT

Enterovesical fistula (EVF) is a fistulous communication between the intestine and the bladder. It is uncommon and its classic clinical manifestations are the presence of pneumaturia, fecaluria, suprapubic pain and recurrent urinary infections. Surgical repair of EVF leads to rapid correction of both diarrhea and metabolic abnormalities. We report a 73-year-old diabetic woman with a neurogenic bladder secondary to a spine meningioma. She presented with diarrhea, vomiting, impaired consciousness and metabolic acidosis. She developed hypernatremia, hypokalemia, hypocalcemia, and hypophosphatemia, which were successfully corrected.

ABSTRACT

Resumen Introducción: El shock hemorrágico es una de las causas más comunes de muerte en pacientes con trauma debido a que pone en marcha un círculo vicioso de mecanismos que incluyen hipotermia, acidosis y coagulopatía. Para mitigar estos efectos, se han propuesto estrategias de control de daños, incluido el aporte controlado de líquidos con hipotensión permisiva contemplando metas en la presión arterial sistólica para mantener una adecuada perfusión de los tejidos. Objetivo: Conocer información actualizada acerca del manejo de la hipotensión permisiva en pacientes con trauma. Metodología: Se buscó información en las bases de datos Web-of-Science y Scopus de los últimos cinco años. El resultado arrojó un total de 118 artículos de los cuales se tomaron 30, según los criterios de inclusión y exclusión. Resultados: Todos los artículos consideran el uso de la hipotensión permisiva como una buena opción para el manejo de los pacientes con trauma e hipotensión, sin embargo, difieren en qué momento es adecuado utilizarlo y en qué condiciones se debe realizar. Conclusiones: Si bien la hipotensión permisiva se ha convertido en uno de los pilares fundamentales en el manejo prehospitalario del paciente con trauma, se requieren estudios investigativos en humanos para soportar cuándo y cómo debe utilizarse.


Abstract Introduction: Hemorrhagic shock is one of the most common causes of death in trauma patients, because it sets in motion a vicious cycle of mechanisms, including hypothermia, acidosis, and coagulopathy. To mitigate these effects, damage control strategies have been proposed, including the controlled intake of fluids with permissive hypotension, contemplating goals in systolic blood pressure, and thus, maintaining adequate tissue perfusion. Objective: The present research aimed to review the literature in search of updated information about the management of permissive hypotension in patients with trauma. Methodology: Information was searched in the Web-of-Science and Scopus databases in the last five years. The result yielded a total of 118 articles, of which 30 were taken according to the inclusion and exclusion criteria. Results: All the articles consider the use of permissive hypotension as a good option for the management of patients with trauma and hypotension, however, they differ when it is appropriate to use it and under what conditions it should be performed. Conclusions: Although permissive hypotension has become one of the fundamental pillars in the prehospital management of the patient with trauma, research studies in humans are required to support when and how it should be used.

ABSTRACT

Introducción: El objetivo del presente estudio fue establecer un modelo predictivo de mor-talidad en recién nacidos de alto riesgo. Métodos: el presente es un estudio epidemiológico, observacional y transversal, realizado en el Hospital Ginecológico Isidro Ayora, Quito, Ecuador, en 2019, incluyó 220 recién nacidos de alto riesgo. Resultados: Se incluyeron 220 Recién nacidos de alto riesgo. No existen asociaciones significativas con factores prenatales, pero sí una relación estadística con el peso, la edad gestacional, el puntaje de APGAR, las necesidades de reanimación y la presencia de anomalías congénitas; también, con shock, hemorragia pulmonar, hiperglucemia, acidosis y estancia hospitalaria. no existen asociaciones significativas con factores prenatales, pero sí una relación estadística con el peso, la edad gestacional, el puntaje de APGAR, las necesidades de reanimación y la presencia de anomalías congénitas; también, con shock, hemorragia pulmonar, hiperglucemia, acidosis y estancia hospitalaria. Conclusión: La presencia de mayor exceso de bases, mínima FiO2, choque séptico, al menos un defecto congénito, con pequeño para la edad gestacional, determina un 80% de probabilidad de muerte. Si el exceso de bases es superior a -12 mEq/L, el lactante tiene 13 veces más probabilidades de morir, y si requiere una FiO2 mínima superior al 29%, tiene 4.2 veces más probabilidades de morir. La fiabilidad del aumento de bases en exceso predice un 76,3% más de riesgo de muerte.


Introduction: The aim of this study was to establish a predictive model of mortality in high-risk newborns. Methods: An epidemiological, observational, and cross-sectional study was carried out at the Isidro Ayora Gynecological Hospital, Quito, Ecuador in 201. The study included 220 high-risk newborns. Results: No significant associations with prenatal factors were found, but a statistical rela-tionship with weight, gestational age, Appearance, Pulse, Grimace, Activity, and Respiration (APGAR) score, resuscitation needs, and the presence of congenital anomalies in addition to shock, pulmonary hemorrhage, hyperglycemia, acidosis, and hospital stay was noted. Conclusion: The presence of a more significant base excess, minimum fraction of inspired oxygen (FiO2), septic shock, and at least one congenital defect with small gestational age determined an 80% probability of death. If the base excess was > −12 mEq/L, the infant was 13 times more likely to die, and if the infant required a minimum FiO2 > 29%, the newborn was 4.2 times more likely to die. The reliability of the excess base increase predicted a 76.3% higher risk of death.

ABSTRACT

This study aims to determine the relationship between indicators of the motor activity, pH factor, rumen and rectal temperature within 10 days after calving and to analyze the possibility of using the studied parameters as prognostic signs for diagnosing sub-acute rumen acidosis (SARA). The measurements were taken using bolus with sensors designed to monitor cow health. The motor activity, pH factor and ruminal temperature of 10 cows were measured during 10 days at a measurement interval of every 60 seconds. Next, the researchers calculated the average values of the obtained readings, which were divided into 2 groups according to a measurement interval of every 12 hours. Rectal temperature was measured using a veterinary thermometer every 12 hours (at 8 a.m. and at 8 p.m.). As a result, 200 measurements were obtained. Descriptive sampling statistics were calculated using the SPSS Statistics program. An increase in motor activity reduces the pH level of the rumen environment. Lowering the pH factor of the rumen environment leads to an increase in ruminal temperature. There is a positive statistically significant correlation between ruminal and rectal temperature. The nosology of SARA can be predicted by measuring the motor activity and rectal temperature of dairy cows.(AU)


Este estudo visa determinar a relação entre indicadores de atividade motora, fator de pH, temperatura ruminal e retal em até 10 dias após o parto e analisar a possibilidade de utilizar os parâmetros estudados como sinais prognósticos para o diagnóstico de acidose ruminal subaguda (SARA). As medições foram feitas usando bolus com sensores projetados para monitorar a saúde das vacas. A atividade motora, o fator de pH e a temperatura ruminal de 10 vacas foram medidos durante 10 dias em intervalos de medição de 60 segundos. A seguir, os pesquisadores calcularam os valores médios das leituras obtidas, que foram divididos em 2 grupos de acordo com um intervalo de medição a cada 12 horas. A temperatura retal foi medida com um termômetro veterinário a cada 12 horas (às 8h e às 20h). Como resultado, foram obtidas 200 medições. As estatísticas de amostragem descritiva foram calculadas usando o programa SPSS Statistics. Um aumento na atividade motora reduz o nível de pH do ambiente ruminal. A redução do fator de pH do ambiente ruminal leva a um aumento da temperatura ruminal. Existe uma correlação positiva estatisticamente significativa entre a temperatura ruminal e retal. A nosologia com SARA pode ser prevista medindo a atividade motora e a temperatura retal de vacas leiteiras.(AU)

ABSTRACT

Concern with antimicrobial resistance in animal production systems increases the interest toward integrative therapies. The objective of the present report was to report an integrative approach to a goat undergoing rumenotomy. A goat with ruminal acidosis underwent rumenotomy, corrective rumen suture, moxibustion, and treatment of the surgical wound (TFO) with sugar. In the first twenty days, acupuncture was performed on ST36, indirect moxibustion on Sp6 and CV8, and TFO with antibiotic ointment and sugar. The wound contracted 2cm, there was gradual return of ruminal dynamics, and moderate pain. Acupuncture continued from D21 to D50 on Yin tang, BL13, BL20, BL23, and BL22. Although there was drainage of ruminal fluid, the wound contracted 4cm during this period, pain was absent, and ruminal dynamics normal. During the last thirty days, the acupuncture technique surround the dragon was used and BL13 point needled, with complete closure of the wound. The TFO from D21 was performed solely with sugar. During treatment, there was modulation of the inflammatory response, with formation of granulation tissue and neovascularization. On D84, fibrinogen was 100mg/dL. The authors conclude that the use of sugar, acupuncture, and moxibustion contributed to return of normal ruminal motility, wound contraction, and complete tissue reepithelization.(AU)


A preocupação com a resistência antimicrobiana nos sistemas de produção animal aumenta o interesse pelas terapias integrativas. Objetiva-se relatar a abordagem integrativa ao paciente caprino submetido à ruminotomia. Uma cabra com acidose ruminal foi submetida à ruminotomia, ruminorrafia, moxabustão, acupuntura e tratamento da ferida operatória (TFO) com açúcar. Nos primeiros vinte dias realizou-se acupuntura em ST36, moxa indireta em Sp6 e CV8, TFO com pomada antibiótica e açúcar. A ferida contraiu 2cm, houve retorno gradual da dinâmica ruminal e dor moderada. A acupuntura continuou de D21 a D50 em Yin tang, BL13, BL20, BL23 e BL22. Apesar da ferida drenar fluido ruminal teve contração de 4cm nesse período, ausência de dor e retorno fisiológico da dinâmica ruminal. Nos últimos trinta dias foi realizada a técnica de acupuntura cercar o dragão e punturou-se o ponto BL13, com fechamento completo da ferida. O TFO a partir do D21 foi realizado somente com açúcar. Durante tratamento houve modulação da resposta inflamatória com formação de tecido de granulação e neoangiogênesse, o D84 revelou fibrinogênio 100mg/dL. Conclui-se que a utilização do açúcar, acupuntura e moxabustão contribuíram para o retorno fisiológico da motilidade ruminal, contração da ferida e completa reepitelização tecidual.(AU)

ABSTRACT

Abstract Introduction: The control of metabolic acidosis in dialysis patients focuses on the supply of bicarbonate during the dialysis session, and it is not standard in all hemodialysis to assess serum bicarbonate concentrations. Bicarbonate expressed in blood gas analysis is the most sensitive standard of analysis and it is measured indirectly, using the Henderson-Hasselbalch equation. There are no studies in this population evaluating the concordance between the calculated bicarbonate with the direct method of biochemical analysis. The aim of this study was to analyze the concordance between the measured and calculated serum bicarbonate levels using blood gas analysis. Methods: We analyzed blood samples from chronic kidney patients undergoing hemodialysis, using the same sample of bicarbonate analysis by biochemistry and gasometry. The concordance was assessed using the Bland-Altman method. Results: 51 samples were analyzed. The analysis revealed a high correlation (r = 0.73) and a mean difference (bias) of 1.15 ± 3 mmol/L. The median time between collection and examination was 241 minutes. Discussion: We can conclude that the biochemical bicarbonate analysis compared to that calculated from blood gas analysis in chronic renal patients was consistent. For greater concordance between the data, it is important that the time between the collection of the samples and the referral to the laboratory for carrying out the dosages does not exceed four hours. The serum bicarbonate dosage can result in cost savings when compared to that of bicarbonate in blood gas analysis.


Resumo Introdução: O controle da acidose metabólica em pacientes dialíticos está voltado, principalmente, para o suprimento de bicarbonato durante a sessão de diálise, não sendo padrão em todas as hemodiálises avaliar as concentrações séricas do bicarbonato. O bicarbonato expresso na gasometria é considerado o padrão mais sensível de análise e é medido indiretamente por meio da equação de Henderson-Hasselbalch. Não há estudos nessa população avaliando a concordância do bicarbonato calculado com o método direto de análise bioquímica. O objetivo deste estudo é analisar a concordância entre o bicarbonato sérico medido e o calculado por meio da gasometria. Métodos: Foram analisadas amostras de sangue de pacientes renais crônicos em hemodiálise sendo feito na mesma amostra de análise do bicarbonato pela bioquímica e análise pela gasometria. A concordância foi avaliada pelo método de Bland-Altman. Resultados: Foram analisados um total de 51 amostras. A análise de correlação revelou alta correlação (r = 0.73) e a diferença média (bias) de 1.15 ± 3 mmol/L. O tempo mediano entre a realização da coleta e do exame foi de 241 minutos. Discussão: Podemos concluir que a realização da dosagem bioquímica do bicarbonato comparada com a calculada a partir da gasometria em pacientes renais crônicos foi concordante. Para maior concordância entre os dados, é importante que o tempo entre a coleta das amostras e o encaminhamento ao laboratório para a realização das dosagens não exceda quatro horas. A dosagem do bicarbonato sérico pode resultar numa economia de custos comparada à do bicarbonato da gasometria.

ABSTRACT

In this study we evaluated the effects of the prepartum anionic diet on the electrolyte balance and calcemia of high producing dairy cows in the first days of lactation, and investigated the impact on the frequency of subclinical hypocalcemia (SCH). Sixty healthy Holstein cows, producing 30 kg of milk/day, handled in intensive system (compost barn), were distributed in groups (n=15) according to lactation order: first, second, third, and fourth to sixth. In the last three weeks before calving they received a diet with negative DCAD (-6mEq/100g DM) and high chloride content. After calving, they received a diet with positive DCAD (18mEq/100g DM). Urine pH was measured before calving. Serum Na+, Cl-, K+, and total Ca concentrations, and the strong ion difference (SID3) were determined in samples taken soon after calving (0h), 24, 48, 72 and 96h after. The frequencies of SCH were determined considering the critical value of 2.125mmol/L (8.5mg/dL). Two-way repeated measures ANOVA and chi-square test were used for comparisons. The cows eliminated acidic urine before calving. Na+, K+, Cl-, and SID3 values did not differ between groups. Na+ and K+ did not vary between days; Cl- was elevated at calving and decreased until 72h; and SID3 was reduced at calving and increased up to 48h. The Ca levels were reduced until 24h and increased up to 72h. Cows of third and fourth to sixth lactations presented lower values up to 24h. SCH was observed in almost half of the cows (43.3% to 55%) until 48h. The maintenance of hypocalcemia for three or more consecutive days occurred in 53.3% of third and fourth to sixth lactations cows. Ingestion of a high chloride prepartum anionic diet led to hyperchloremic acidosis and this imbalance was reversed on the second postpartum day. The induced effects on electrolyte and acid-base balances were not able to prevent the occurrence of SCH in the first days of lactation.(AU)


Os objetivos do estudo foram avaliar os efeitos que a dieta aniônica pré-parto provoca sobre o equilíbrio eletrolítico e sobre a calcemia de vacas leiteiras de alta produção nos primeiros dias de lactação, e verificar o impacto sobre a frequência da hipocalcemia subclínica (HSC). Sessenta fêmeas hígidas HPB, com produção de 30 kg de leite/dia, manejadas em sistema intensivo (compost barn), foram distribuídas por grupos (n=15) de acordo com a ordem de lactação: primeira, segunda, terceira e quarta a sexta. Nas três semanas pré-parto receberam dieta com DCAD negativa (-6mEq/100g MS) e teor de cloreto elevado. Após o parto receberam dieta com DCAD positiva (18mEq/100g MS). O pH da urina foi mensurado antes do parto. As concentrações séricas de Na+, Cl-, K+ e Ca total e a diferença de íons fortes (SID3) foram determinadas em amostras colhidas ao parto (0h), 24, 48, 72 e 96h após. As frequências de HSC foram determinadas considerando-se o valor crítico de 2,125mmol/L (8,5mg/dL). ANOVA de medidas repetidas e teste de qui-quadrado foram empregados para as comparações. As vacas eliminavam urina ácida antes do parto. Os valores de Na+, K+, Cl- e SID3 não diferiram entre os grupos. Na+ e K+ não variaram entre os dias; Cl- era elevado ao parto e diminuiu até 72h; e SID3 era reduzida ao parto e aumentou até 48h. A calcemia era reduzida até 24h e se elevou até 72h. Vacas de terceira e de quarta a sexta lactações apresentaram valores mais baixos até 24h. A HSC foi observada em quase metade das vacas (43,3% a 55%) até 48h. A manutenção de hipocalcemia por três ou mais dias seguidos ocorreu em 53,3% das vacas de terceira e de quarta a sexta lactações. A ingestão de dieta aniônica pré-parto com alto teor de cloreto provocou acidose hiperclorêmica e este desequilíbrio se reverteu no segundo dia pós-parto. Os efeitos induzidos sobre os equilíbrios eletrolítico e ácido base não foram capazes de prevenir a ocorrência de HSC nos primeiros dias da lactação.(AU)

ABSTRACT

ABSTRACT Introduction: Metabolic acidosis is associated with the high mortality seen in hemodialysis patients. The panorama of metabolic acidosis in hemodialysis in Brazil is unclear since 1996 when the analysis of bicarbonate levels was no longer a compulsory exam. We aimed to establish the prevalence of metabolic acidosis in a hemodialysis population and analyze the factors associated with low bicarbonate levels. Methods: A cross-sectional study was carried out to assess the prevalence of metabolic acidosis in adults undergoing regular hemodialysis from January to April 2017, in four dialysis centers from Niteroi, Rio de Janeiro, Brazil, and surroundings. For blood gas analysis, samples of 2 mL were collected in heparinized syringes before a midweek dialysis session. Results: 384 patients with a mean age of 58.1 ± 15.8 years (54.5% men and 63.0%, non-white) were included. Approximately 30% had diabetes and 48%, hypertension. Nearly 88% used primary arteriovenous fistula as vascular access. The pre-dialysis mean serum tCO2 in the midweek session was 22.7 ± 3.0 mEq/L. The prevalence rate of serum bicarbonate below DOQI recommendation (22 mEq/L or higher) was 40.3%, and 6.5% had serum bicarbonate < 18 mEq/L. The dialyzer use count and the use of low-flux dialyzers were negatively associated whereas age and the standard Kt/V values were positively associated with the serum bicarbonate levels. Conclusion: The findings were in agreement with global data reported in previous studies. However, because the sample was relatively small and non-representative of the Brazilian population, a more comprehensive study, addressing national data is necessary to substantiate our findings.


RESUMO Introdução: A acidose metabólica está associada à elevada mortalidade observada em pacientes em hemodiálise. O panorama da acidose metabólica na hemodiálise no Brasil perdeu visibilidade em 1996, ano em que a análise dos níveis de bicarbonato deixou de ser obrigatória. Nosso objetivo foi estabelecer a prevalência da acidose metabólica em uma população em hemodiálise e analisar os fatores associados a baixos níveis de bicarbonato. Métodos: O presente estudo transversal avaliou a prevalência de acidose metabólica em adultos regularmente submetidos a hemodiálise de janeiro a abril de 2017, em quatro centros de diálise situados em Niterói e arredores no Estado do Rio de Janeiro. Para análise de gasometria, foram colhidas amostras de 2 mL em seringas heparinizadas antes das sessões de diálise do meio de semana. Resultados: Foram incluídos 384 pacientes com idade média de 58,1 ± 15,8 anos (54,5% homens; 63,0% não brancos). Aproximadamente 30% tinham diabetes e 48% apresentavam hipertensão. Cerca de 88% usavam fístula arteriovenosa primária como acesso vascular. A concentração sérica média pré-diálise de tCO2 na sessão do meio de semana foi de 22,7 ± 3,0 mEq/L. A taxa de prevalência de bicarbonato sérico abaixo do valor recomendado no DOQI (22 mEq/L ou superior) foi de 40,3%; 6,5% dos pacientes apresentaram bicarbonato sérico < 18 mEq/L. Os níveis séricos de bicarbonato apresentaram associações negativas com número de usos do dialisador e uso de dialisadores de baixo fluxo e associações positivas com idade e valores do Kt/V standard. Conclusão: Os resultados foram concordantes com dados globais relatados em estudos anteriores. Contudo, como a amostra era relativamente pequena e não representativa da população brasileira, são necessários estudos mais abrangentes que venham a abordar dados nacionais para consubstanciar nossos achados.

ABSTRACT

Este trabalho descreve um surto de rumenite e abomasite decorrente de sobrecarga de carboidratos em um rebanho de 238 bezerros, com idades entre 12 e 15 meses, causada pela ingestão dos frutos de Enterolobium contortisiliquum. As taxas de morbidade, mortalidade e letalidade foram de, respectivamente, 12,7%, 5,2% e 42,1%. Clinicamente, os bovinos apresentaram fotossensibilização, salivação e diarreia. Os achados de necropsia foram semelhantes nos dois bezerros necropsiados e consistiram de fotodermatite e rumenite ulcerativa multifocal, subaguda a crônica, e abomasite. A relevância deste relato é que, pela primeira vez, foi possível associar a ocorrência da rumenite devido à sobrecarga de carboidratos com a intoxicação espontânea por E. contortisiliquum em bovinos, confirmando achados anteriormente descritos em experimentos realizados com ovinos.(AU)

ABSTRACT

Currently, the use of sodium bicarbonate (SB) as an ergogenic supplement has been linked to improved performance in several high-intensity and short time interval modalities because it is a natural buffer of the body fluids of the human body. This study aimed to evaluate the acute effect of SB supplementation on muscle strength endurance of resistance training practitioners. Crossover clinical trial, placebo-controlled (PL), and single-masked, included 10 trained adult men. The maximum repetition (1RM) and exhaustion tests with 80% 1RM were performed in the extensor chair and direct thread. In all sessions, the volunteers were verbally stimulated, the total maximum repetitions in the exercises and the blood lactate concentration were measured. SB was supplemented at a dose of 0.3 g/kg body mass. Statistical analysis was performed using SPSS version 25.0. The Shapiro­Wilktest was used to evaluate the normality of the data, and the Student's t-test was used for independent and paired samples. The size of the Cohen's effect was calculated, and the significance level was set at p<0.05. Comparing the supplements, no significant differences were found in all variables tested. However, when comparing pretest and posttest periods, significant differences were found between lactate concentrations, with considerably large effect sizes (> 1.00).SB supplementation by endurance training practitioners induces blood alkalosis, which reduces fatigue and possibly improves muscle strength endurance


Atualmente, o uso de bicarbonato de sódio (SB) como suplemento ergogênico tem sido associado a um melhor desempenho em várias modalidades de alta intensidade e intervalos de tempo curtos, pois é um amortecedor natural dos fluidos corporais do corpo humano. Este estudo teve como objetivo avaliar o efeito agudo da suplementação de SB na resistência da força muscular de praticantes de treinamento de resistência. Ensaio clínico cruzado, controlado por placebo (PL) e com máscara única, incluiu 10 homens adultos treinados. Os testes de repetição máxima (1RM) e exaustão com 80% de 1RM foram realizados na cadeira extensora e na rosca direta. Em todas as sessões, os voluntários foram estimulados verbalmente, foram medidas as repetições máximas totais nos exercícios e a concentração de lactato sanguíneo. O SB foi suplementado na dose de 0,3 g / kg de massa corporal. A análise estatística foi realizada no SPSS versão 25.0. O teste Shapiro-Wilk foi usado para avaliar a normalidade dos dados, e o teste t de Student foi usado para amostras independentes e emparelhadas. O tamanho do efeito de Cohen foi calculado e o nível de significância foi estabelecido em p <0,05. Comparando os suplementos, não foram encontradas diferenças significativas em todas as variáveis testadas. No entanto, ao comparar os períodos pré e pós-teste, foram encontradas diferenças significativas entre as concentrações de lactato, com tamanhos de efeito consideravelmente grandes (> 1,00). A suplementação de SB por praticantes de treinamento de resistência induz alcalose no sangue, o que reduz a fadiga e possivelmente melhora a resistência da força muscular.

ABSTRACT

The causes of death of cattle kept in pre-export feedlots (PEFs) and in feedlot for finishing for slaughter are described. Two studies were conducted: a retrospective study of mortality cases in feedlots from 2000 to 2017 registered at the "Laboratório Regional de Diagnóstico" of the "Faculdade de Veterinária" of the "Universidade Federal de Pelotas"; and a prospective study from January 2018 to August 2019, following up 22 feedlots for finishing and six PEFs for the export of live cattle. From January 2000 to August 2019 samples of 150 cases of diseases that affected feedlot cattle were received from 22 feedlots for finishing and 115 of the six PEFs followed. Mortality considering all diagnosed diseases was significantly higher in feedlots for finishing (p<0.05), than in PEFs for the export of live cattle, of 1% and 0.12%, respectively. Diseases of the digestive system were the most important causes, of death in feedlots regardless of its purpose. Acidosis presented the highest mortality rates both in feedlot for finishing (3.33%) as in PEFs for export (0.95%). In all cases the disease occurred due to failure in the adaptation of animals to the ingestion of concentrated foods. Bovine tick fever and pneumonia presented mortality rates of 0.13% and 0.09%, respectively in PEFs. In the feedlot for finishing seneciosis was the second cause of death due to cattle coming from areas with high infestation by the plant. In the present study, it was possible to identify the main diseases that occur in cattle feedlots for finishing or for the export of live animals in the southern region of Rio Grande do Sul. These diseases are known in other systems of cattle breeding and can be prevented or controlled through management, chemoprophylaxis or vaccination, minimizing losses due to mortality.(AU)


Descrevem-se as causas de morte de bovinos mantidos confinados em estabelecimentos pré-embarque (EPEs) para exportação de animais vivos e em estabelecimentos de terminação para abate. Foram realizados dois estudos: um retrospectivo dos casos de mortalidade em confinamentos de 2000 a 2017 registrados no Laboratório Regional de Diagnóstico da Faculdade de Veterinária da Universidade Federal de Pelotas; e um estudo prospectivo de janeiro de 2018 a agosto de 2019, acompanhando-se 22 confinamentos de terminação e seis EPEs para exportação de bovinos vivos. No total, de janeiro de 2000 a agosto de 2019 foram recebidos no LRD-UFPel amostras de 150 casos de enfermidades que afetaram bovinos confinados, 35 provenientes de 22 confinamentos de terminação e 115 dos seis EPEs acompanhados. A mortalidade considerando-se todas as enfermidades diagnosticadas foi significativamente maior nos confinamentos para terminação (p<0,05), do que nos EPEs para exportação de bovinos vivos, de 1% e 0,12%, respectivamente. As doenças do sistema digestivo foram as causas de morte mais importante nos confinamentos, independente da finalidade. Acidose apresentou as maiores taxas de mortalidade tanto nos confinamentos para terminação (3,33%) como nos EPEs para exportação (0,95%). Em todos os casos a doença ocorreu devido a falha na adaptação dos animais à ingestão de alimentos concentrados. Tristeza parasitária bovina e pneumonias apresentaram taxas de mortalidade de 0,13% e 0,09, respectivamente em EPEs de exportação. Nos confinamentos para terminação a seneciose foi a segunda causa de morte devido aos bovinos serem provenientes de áreas com alta infestação pela planta. Este estudo permitiu identificar as principais enfermidades diagnosticadas em confinamentos para terminação de bovinos ou para exportação de bovinos vivos na região Sul do Rio Grande do Sul. Observou-se que são doenças que ocorrem em outros sistemas de criação de bovinos e que podem ser prevenidas ou controladas por meio de manejo, quimioprofilaxia ou vacinação, minimizando prejuízos por mortalidade de animais.(AU)

ABSTRACT

Introducción: el trauma se considera un problema de salud pública, siendo la mortalidad el principal indicador de su magnitud. La detección de los componentes de la triada letal tienen relevancia clínica en la mortalidad de quienes padecen un trauma grave (ISS> 16 puntos). Objetivo: determinar las características operativas de la tríada letal en pacientes que ingresaron de enero 2012 a diciembre 2017 al servicio de urgencias de los Hospitales de San José e Infantil Universitario de San José de Bogotá con diagnóstico de trauma grave, para predecir mortalidad. Métodos: estudio de casos y controles para pruebas diagnósticas en este período con el fin de evaluar la mortalidad en los pacientes con trauma grave definido por una escala validada internacionalmente INJURY SEVERITY SCORE en este caso mayor de 16 puntos. Resultados: se incluyeron 500 casos; las características predominantes fueron trauma craneoencefálico en 74% de pacientes fallecidos y 43.8% de los egresados vivos, hipotermia (<36°C) evidenciada en 98,2% de los casos que egresaron vivos (controles) y en 96% de fallecidos (casos) y acidosis con 2,7% de los que sobrevivieron y 68% de los fallecidos. Esta triada letal presentó una sensibilidad de 0.02 y especificidad de 1, cuyos valores predictivos negativos fueron de 1 y 0.90. Conclusión: la sensibilidad de la triada letal en el estudio fue menor a la reportada en la literatura y la especificidad mayor con valores predictivos altos, considerándose así no determinante en la mortalidad de los pacientes con trauma severo.


Introduction: trauma is considered a public health problem, and mortality rate is the main indicator of its magnitude. Clinical recognition of the lethal triad components is relevant as a predictor of death in major trauma patients. Objective:to determine the operative features of the lethal triad in patients admitted to the emergency services of the San José and Infantil Universitario de San José Hospitals in Bogota with major trauma injuries, from January 2012 to December 2017, to estimate the probability of death. Methods: a case and control study of results in diagnostic tests during said period in order to evaluate mortality rate in severe cranioencephalic trauma patients. Results: 500 cases were included; the predominant characteristics were brain trauma in 74% of deceased patients and 43.8% of survivors, moderate hypothermia (equal or < 36°C) was evidenced in 98.2% among survivors and in 96% of non-survivors and acidosis in 2.7% of those who survived and 68% of those who died. This lethal triad had a sensibility and specificity of 0.02 and 1, with negative predictive values of 1 and 0.90. Conclusion: The sensitivity of the lethal triad was less than that reported in the literature and specificity was greater with high predictive values, thus it was considered that the triad was non determinant in the mortality rate of severe trauma patients.

ABSTRACT

La metformina es un medicamento ampliamente utilizado como tratamiento de primera línea en diabetes mellitus tipo 2, su mecanismo de acción incluye impedir la elaboración de glucosa hepática, disminuye el transporte de glucosa a nivel intestinal entre otros. Uno de sus efectos adversos es la acidosis láctica, la mortalidad en estos pacientes aún es elevada a pesar de tratamientos modernos con terapia de sustitución renal. Presentación del caso: Presentamos el caso de una paciente femenina de 16 años que ingresó al servicio de emergencia debido a intoxicación con metformina (30 tabletas de 500mg) secundario a intento autolítico. La paciente se presentó somnolienta, con ruidos hidroaéreos aumentados, y relajación de esfínteres. Los controles gasométricos mostraron cifras de lactato en ascenso, llegando a valores de hasta 19,5 mmol/L. Paciente requirió ventilación mecánica invasiva motivo por el cual, ingresó al servicio de Terapia Intensiva para manejo de fallo multiorgánico, se inició tratamiento sustitutivo renal con ciclos prolongados. Paciente fue dada de alta del servicio de terapia intensiva en su quinto día de hospitalización y continuó su tratamiento multidisciplinar a cargo del servicio de medicina interna. Conclusiones: La metformina al ser un medicamento ampliamente usado a nivel mundial, todo servicio de emergencias debería estar preparado para identificar los casos de intoxicación por este fármaco. Dentro de las intervenciones se incluye: fluidoterapia, drogas vasoactivas, soporte ventilatorio invasivo, bicarbonato de sodio y terapia de reemplazo renal; todas ellas se brindaron a nuestra paciente con resultados exitosos.


Metformin is a medicine used as first-line treatment in type 2 diabetes mellitus, its mechanism of action includes among others: preventing the production of hepatic glucose, decreases the transport of glucose at intestinal level. One of its adverse effects is lactic acidosis, especially when its used in autolytic attempts. Mortality in these patients is still high despite modern treatment with renal replacement therapy. Case presentation: We present the case of a 16-year-old female patient who entered the emergency service due to metformin poisoning (30 tablets of 500mg) secondary to autolytic attempt. The patient was drowsy, with increased hydroaereal noises, and relaxation of sphincters. Gasometric controls showed rising lactate figures, reaching values of up to 19.5 mmol/L. Patient required invasive mechanical ventilation which is why, entered the intensive therapy service for management of multiorgan failure, renal replacement treatment was initiated with prolonged cycles. Patient was discharged from intensive care on her fifth day of hospitalization and continued her treatment in charge of the internal medicine service. Conclusions: Metformin being a widely used medicine worldwide, every emergency service should be prepared to identify cases of this drug. Interventions include: fluid therapy, vasoactive drugs, invasive ventilatory support, sodium bicarbonate, and renal replacement therapy; All of them were provided to our patient with successful results.

ABSTRACT

OBJECTIVE@#To investigate the effects of acid-sensing ion channels (ASICs) on electrophysiological epileptic activities of mouse hippocampal pyramidal neurons in the extracellular acidotic condition.@*METHODS@#We investigated effects of extracellular acidosis on epileptic activities induced by elevated extracellular K concentration or the application of an antagonist of GABA receptors in perfusate of mouse hippocampal slices under field potential recordings. We also tested the effects of extracellular acidosis on neuronal excitability under field potential recording and evaluated the changes in epileptic activities of the neurons in response to pharmacological inhibition of ASICs using a specific inhibitor of ASICs.@*RESULTS@#Extracellular acidosis significantly suppressed epileptic activities of the hippocampal neurons by converting ictal-like epileptic activities to non-ictal-like epileptic activities in both high [K ]o and disinhibition models, and also suppressed the intrinsic excitability of the neurons. ASICs inhibitor did not antagonize the inhibitory effect of extracellular acidosis on ictal epileptic activities and intrinsic neuronal excitability, but exacerbated non-ictal epileptic activities of the neurons in extracellular acidotic condition in both high [K]o and disinhibition models.@*CONCLUSIONS@#ASICs can differentially modulate ictal-like and non-ictallike epileptic activities via its direct actions on excitatory neurons.
