The present study aimed to evaluate increasing levels of fish waste oil in diets for laying hens on serum biochemistry profile. 192 Hisex White laying hens at 29 weeks of age were used, with water and food ad libitum. The experimental design was completely randomized consisting of eight treatments corresponding to the inclusion levels of fish waste oil (0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 and 3.5%) in the diets, with four replicates of six birds each. Data collected were subjected to polynomial regression at 5% of significance. Significant differences (P<0.05) were observed in triglycerides, glucose, total cholesterol, and uric acid. These parameters presented a decrease when hens fed diets with higher level of fish waste oil. The results of the present study indicated that the inclusion of fish waste oil caused a significant effect in the serum biochemical profile of laying hens, especially in glucose, triglycerides, total cholesterol, and uric acid concentrations. The inclusion level of 3.5% of fish waste oil caused larger disequilibrium in the serum biochemical profile of laying hens.(AU)

O presente estudo objetivou avaliar os níveis crescentes de óleo de resíduo de pescado em dietas para poedeiras leves sobre o perfil bioquímico sérico. Foram utilizadas poedeiras Hisex White com 29 semanas, com água e ração ad libitum. O delineamento experimental foi inteiramente ao acaso, consistindo de oito tratamentos correspondentes aos níveis de inclusão de óleo de resíduo de pescado (0; 0,5; 1,0; 1,5; 2,0; 2,5; 3,0 e 3,5%) nas dietas, com quatro repetições de seis aves cada. Os dados coletados foram submetidos à regressão polinomial a 5% de significância. Diferenças significativas (P<0,05) foram observadas nas concentrações de triglicerídeos, glicose, colesterol total e ácido úrico. Esses parâmetros apresentaram uma diminuição quando as aves se alimentaram com rações contendo maior nível de óleo do resíduo de pescado. Os resultados do presente estudo indicaram que a inclusão de óleo do resíduo de pescado acarretou um efeito significativo no perfil bioquímico sérico de poedeiras, principalmente nas concentrações de glicose, triglicerídeos, colesterol total e ácido úrico. O nível de inclusão de 3,5% do óleo do resíduo de pescado acarretou maior desequilíbrio no perfil bioquímico sérico das poedeiras.(AU)

Introduction: Cancer is one of the leading causes of morbidity and mortality worldwide. There are few studies showing adjusted models with other predictors of mortality by a conceptual model perspective. Objective: The objective of this study was to verify the prediction of albumin and Prognostic Nutritional Index (PNI) with in-hospital mortality in cancer patients. Method: Retrospective study was performed from 2014 to 2016 with 262 cancer patients (gastrointestinal tract, male genital organs, breast, metastasis, urinary tract, head and neck and others). Demographic data, blood counts, C-reactive protein, albumin, and haematological indexes (Prognosis nutritional index - PNI, Neutrophils to lymphocytes ratio - NLR, Monocytes lymphocytes ratio - MLR, Platelets to lymphocytes ratio - PLR and Platelets to albumin ratio - PAR), nutritional diagnoses and hospital outcomes (discharge or death) were collected. The cumulative probability of death was calculated by Kaplan-Meier curves, and survival analyses were performed using the Cox proportional hazards model. Results: The frequency of death among the study patients was 10.7% (28). Among the patients who died, 99.2% (26) presented some degree of malnutrition (p=0.004). In the multivariate analysis, serum albumin (<3 g/dL) was independently associated with in-hospital mortality (HR=3.43, 95% CI 1.11-10.63). On the other hand, the PNI was not associated with in-hospital mortality. Conclusion: Serum albumin levels during hospitalization were predictors of in-hospital mortality in the population evaluated. These results suggest that the serum levels of this protein can be used in clinical practice, adding prognostic information in patients with cancer

Introducción: El cáncer es una de las principales causas de morbilidad y mortalidad en todo el mundo. Hay pocos estudios que muestren modelos ajustados con otros predictores de mortalidad desde una perspectiva de modelo conceptual. Objetivo: El objetivo de este estudio fue verificar la predicción de la albúmina y el Índice Nutricional Pronóstico (IPN) con la mortalidad hospitalaria en pacientes con cáncer (tracto gastrointestinal, órganos genitales masculinos, mama, metástasis, tracto urinario, cabeza y cuello y otros). Método: Se realizó un estudio retrospectivo de 2014 a 2016 con 262 pacientes con cáncer. Se recogieron datos demográficos, hemogramas, proteína C reactiva, albúmina y índices hematológicos (Índice de Pronóstico Nutricional - IPN, proporción neutrófilos/linfocitos - NLR, proporción monocitos/linfocitos - MLR, proporción plaquetas/linfocitos - PLR y proporción plaquetas/albúmina - PAR), diagnósticos nutricionales y resultados hospitalarios (alta o muerte). La probabilidad acumulada de muerte se calculó mediante curvas de Kaplan-Meier y se realizaron análisis supervivencia utilizando el modelo de riesgos proporcionales de Cox. Resultados: La frecuencia de muerte entre los pacientes del estudio fue del 10,7% (28). Entre los pacientes fallecidos, el 99,2% (26) presentaba algún grado de desnutrición (p=0,004). En el análisis multivariado, la albúmina sérica (<3 g/dL) se asoció de forma independiente con la mortalidad hospitalaria (HR=3,43, IC 95% 1,11-10,63). Por otro lado, el IPN no se asoció con mortalidad intrahospitalaria. Conclusión: Los niveles de albúmina sérica durante la hospitalización fueron predictores de mortalidad intrahospitalaria en la población evaluada. Nuestros resultados sugieren que los niveles séricos de esta proteína se pueden utilizar en la práctica clínica, agregando información de pronóstico en pacientes con cáncer.

Introdução: O câncer é uma das principais causas de morbidade e mortalidade em todo o mundo. Existem poucos estudos mostrando modelos ajustados com outros preditores de mortalidade por uma perspectiva de modelo conceitual. Objetivo: Verificar a predição de albumina e do Índice Nutricional Prognóstico (IPN) com mortalidade intra-hospitalar em pacientes com câncer. Método: Estudo retrospectivo realizado de 2014 a 2016 com 262 pacientes com câncer (trato gastrointestinal, órgãos genitais masculinos, mama, metástases, trato urinário, cabeça e pescoço e outros). Foram coletados dados demográficos, hemograma, proteína C reativa, albumina e índices hematológicos (índice de prognóstico nutricional - IPN; relação neutrófilo por linfócitos - RNL; relação monócitos por linfócitos - RML; relação plaquetas por linfócitos - RPL; e relação plaquetas por albumina ­ RPA), diagnósticos nutricionais e desfechos hospitalares (alta ou óbito). A probabilidade cumulativa de morte foi calculada pelas curvas de Kaplan-Meier e as análises de sobrevivência realizadas usando o modelo de risco proporcional de Cox. Resultados: A frequência de óbito entre os pacientes do estudo foi de 10,7% (28). Entre os pacientes que morreram, 99,2% (26) apresentavam algum grau de desnutrição (p=0,004). Na análise multivariada, a albumina sérica (<3 g/dL) associou-se de forma independente à mortalidade hospitalar (HR=3,43, IC95% 1,11-10,63). Por outro lado, o IPN não foi associado com mortalidade intra-hospitalar. Conclusão: Os níveis de albumina sérica durante a internação foram preditores de mortalidade intra-hospitalar na população avaliada. Esses resultados sugerem que os níveis séricos dessa proteína podem ser utilizados na prática clínica, agregando informações prognósticas em pacientes com câncer

ABSTRACT Objective The present study assessed the differences in nutritional markers (albumin, transferrin, total body fat, and body mass index) and clinical complications (diarrhea, vomiting, and diet interruptions) associated with enteral nutrition. Methods This is an open-label, randomized, two-arm parallel-group controlled clinical trial. Out of 105 patients assessed for eligibility, 35 adult patients were randomly divided into two groups and followed for 28 days. The sample comprised a heterogeneous group of severely ill individuals initially treated in the intensive care units. Neurological conditions (i.e., strokes and brain tumours) were the most common reasons for hospitalization. Patients had one singularity: the clinical need for exclusive enteral nutrition therapy. One group received the diet via gastric tube and the other via a post-pyloric tube. Results The groups presented increases in the calories prescribed and administered, as well as reduced diet discontinuation. Although similar values were observed up to day 21, the post-pyloric group showed increased albumin levels compared to the gastric group on Day 28. Transferrin levels increased over time in both groups. Conclusion There were no differences in the complications recorded between groups, albeit serum albumin significantly increased in the post-pyloric group.

RESUMO Objetivo Avaliar diferenças tanto nos marcadores nutricionais (albumina, transferrina, gordura corporal e índice de massa corporal) quanto nas complicações clínicas (diarreia, vômitos e interrupções na dieta) associadas à nutrição enteral administrada através de duas vias tradicionais. Métodos Este é um ensaio clínico de tratamento, paralelo de dois braços, aberto e randomizado controlado. Dos 105 participantes avaliados para elegibilidade, 35 pacientes adultos foram divididos aleatoriamente em dois grupos e seguidos por 28 dias. A amostra foi formada por um grupo heterogêneo e gravemente enfermo, tratados inicialmente em unidades de terapia intensiva. Condições neurológicas, como acidente vascular e tumores cerebrais foram as razões principais para hospitalização. Os pacientes tinham em comum um aspecto, a saber, a necessidade clínica exclusiva de receber nutrição enteral. Um grupo recebeu a dieta via sonda gástrica e o outro através de sonda pós-pilórica. Resultados Os grupos apresentaram aumento de calorias prescritas e administradas, bem como redução da descontinuação da dieta. Embora valores semelhantes tenham sido observados até o 21° dia, o grupo pós-pilórico apresentou aumento dos níveis de albumina em relação ao grupo gástrico no dia 28. Os níveis de transferrina aumentaram ao longo do tempo em ambos os grupos. Conclusão Não houve diferenças nas complicações registradas entre os grupos, embora níveis séricos de albumina aumentaram significativamente no grupo pós-pilórico.

SUMMARY OBJECTIVE: Serum inflammatory markers and albumin levels provide an assumption for the severity of COVID-19 infection. Our objective was to investigate the determinant role of serum inflammatory markers, albumin, and hemoglobin (Hb) in predicting the diagnosis in patients with a pre-diagnosis of COVID-19. METHODS: Demographic findings, complete blood count and serum biochemical values of the patients analyzed. RESULTS: Of the patients included in the study, 48 were COVID (+) and 253 were COVID (-). Statistically significant difference was found in terms of hemoglobin, mean platelet volume, and monocyte/eosinophil ratio. CONCLUSIONS: The levels of serum albumin, hemoglobin, monocyte/eosinophil ratio, and mean platelet volume can be predictive factors for diagnosis in patients with COVID-19.

Resumen Introducción: Aun con adecuado protocolo de desconexión de la ventilación mecánica (DVM), el procedimiento falla en 15 a 30 % de los casos. Objetivo: Evaluar la asociación entre factores de riesgo independientes y fracaso posextubación en pacientes con DVM en una unidad de cuidados intensivos. Método: Estudio de cohorte, longitudinal, prospectivo, analítico, que incluyó pacientes sometidos a ventilación mecánica por más de 24 horas y que fueron extubados. Se obtuvieron reportes preextubación de hemoglobina, albúmina, fósforo, índice cintura-cadera y puntuación SOFA. Se definió como fracaso de extubación al reinicio de la ventilación mecánica en 48 horas o menos. Resultados: Se extubaron 123 pacientes, 74 hombres (60 %); la edad promedio fue de 50 ± 18 años. Ocurrió fracaso de extubación en 37 (30 %). Como factores de riesgo independentes se asoció hipoalbuminemia en 29 (23.8 %, RR = 1.43, IC 95 % = 1.11-1.85) e hipofosfatemia en 18 (14.6 %, RR = 2.98, IC 95 % = 1.66-5.35); se observaron dos o más factores de riesgo independientes en 22.7 % (RR = 1.51, IC 95 % = 1.14-2.00). Conclusiones: Identificar los factores de riesgo independentes antes de la DVM puede ayudar a reducir el fracaso de la extubación y la morbimortalidad asociada.

Abstract Introduction: Even with an adequate mechanical ventilation weaning (MVW) protocol, the procedure fails in 15 to 30 % of cases. Objective: To assess the association between independent risk factors (IRFs) and post-extubation failure in patients undergoing MVW in an intensive care unit. Method: Longitudinal, prospective, analytical cohort study in patients on mechanical ventilation for more than 24 hours and who were extubated. Pre-extubation reports of hemoglobin, albumin, phosphorus, waist-hip ratio and SOFA score were obtained. Extubation failure was defined as resumption of mechanical ventilation within 48 hours or less. Results: 123 patients were extubated, out of whom 74 were males (60 %); average age was 50 ± 18 years. Extubation failure occurred in 37 (30 %). Hypoalbuminemia was associated as an independent risk factor in 29 (23.8 %, RR = 1.43, 95 % CI = 1.11-1.85) and hypophosphatemia was in 18 (14.6 %, RR = 2.98, 95 % CI = 1.66-5.35); two or more IRFs were observed in 22.7 % (RR = 1.51, 95 % CI = 1.14-2.00). Conclusions: Identifying independent risk factors prior to MVW can help reduce the risk of extubation failure and associated morbidity and mortality.

Abstract Background Telogen effluvium is the most common form of non-scarring alopecia characterized by diffuse hair loss. Ischemia-modified albumin is a marker of oxidative stress and inflammation. Objective The aim of this study was to compare the levels of ischemia-modified albumin of telogen effluvium patients with healthy controls. Methods Ninety-one patients diagnosed with telogen effluvium and 35 healthy volunteers were included in the study. Serum ischemia-modified albumin level was determined by a fast-colorimetric method, and albumin cobalt binding test. The results were evaluated statistically. Results There was no statistically significant difference between the serum albumin values of patient and control groups (p = 0.739). Serum ischemia-modified albumin values were significantly higher in the patients with telogen effluvium than healthy controls (p < 0.001). Study limitations Body mass index values of the patient and control groups could not be calculated. Conclusions To the best of the authors' knowledge, this is the first clinical study to investigate the role of oxidative stress in the pathogenesis of telogen effluvium using ischemia-modified albumin as a biomarker. Based on the results of the present study, it can be considered that oxidative stress plays an important role in the pathogenesis of telogen effluvium. There is a need for further studies to support the results of this study, to demonstrate the possible effects of oxidative stress, and to investigate the other oxidative stress markers in the pathogenesis of telogen effluvium.

Introducción: La albúmina sérica constituye uno de los parámetros utilizados para predecir el riesgo de complicaciones en pacientes intervenidos quirúrgicamente. Objetivo: Evaluar la utilidad de la albúmina sérica como factor pronóstico de fallo múltiple de órganos en pacientes con peritonitis difusa secundaria. Método: Se realizó un estudio observacional, analítico, de cohortes de 54 pacientes con peritonitis difusa secundaria atendidos en la Unidad de Cuidados Intensivos del Hospital General Universitario Carlos Manuel de Céspedes de Bayamo, de la provincia de Granma, durante el 2016. La variable marcadora del pronóstico fue el fallo múltiple de órganos, que se evaluó con la escala Secuencial Organ Failure Assessment. Resultados: En 37,7 % de los pacientes se desarrolló fallo múltiple de órganos; asimismo, el valor promedio de la albúmina sérica al ingreso (desviación estándar) fue 30,3 g/L (+ 3,4) en pacientes con dicha afectación y 33,2 g/L (+ 4,1) sin esta (p=0,012). El riesgo relativo de fallo múltiple de órganos resultó ser de 1,9 (IC: 95 % 1,1-3,2) con albúmina de 30 g/L o menos. En el análisis multivariado la albúmina sérica constituyó un factor independiente de fallo múltiple de órganos junto al índice de APACHE II; mientras que el área bajo la curva receptor operador presentó un valor de 0,7 cuando se estimó la capacidad discriminativa de la albúmina para predecir la no aparición de fallo múltiple de órganos y de 0,2 para predecir su desarrollo. Conclusiones: La albúmina sérica es útil como factor pronóstico de fallo múltiple de órganos en pacientes con peritonitis difusa secundaria.

Introduction: Seric albumin constitutes one of the parameters used to predict the risk of complications in patients surgically intervened. Objective: To evaluate the utility of seric albumin as prediction factor of multiple failure of organs in patients with secondary diffuse peritonitis. Method: An observational, cohorts analytic study of 54 patients with secondary diffuse peritonitis was carried out, they were assisted in the Intensive Cares Unit of Carlos Manuel de Céspedes University General Hospital in Bayamo, Granma, during 2016. The marker variable of prediction was the multiple failures of organs that was evaluated with the Sequential scale Organ Failure Assessment. Results: In the 37.7 % of patients multiple failure of organs was developed; also, the average value of seric albumin at admission (standard deviation) was 30.3 g/L (+ 3.4) in patients with this disorder and 33.2 g/L (+ 4.1) without this disorder (p=0.012). The relative risk of multiple failure of organs was 1.9 (CI: 95 % 1.1-3.2) with albumin of 30 g/L or less. In the multivariate analysis seric albumin constituted an independent factor of multiple failure of organs along with APACHE II index; while the area under the curve receiving operator presented a value of 0.7 when the discriminative capacity of the albumin was considered to predict if the multiple failure of organs was not present and 0.2 to predict its development. Conclusions: Seric albumin is useful as prediction factor of multiple failure of organs in patients with secondary diffuse peritonitis.

Abstract Introduction: Sudden hearing loss is a significant otologic emergency. Previous studies have revealed a coexistence of sudden hearing loss with chronic inflammation. The predictive importance of C-reactive protein/albumin values as a prognostic factor has been shown in various inflammatory and tumoral conditions. Objectives: The aim of this study was to determine whether the C-reactive protein/albumin ratio in sudden hearing loss can be used for prognostic purposes and whether there is a relationship between the neutrophil/lymphocyte ratio and the C-reactive protein/albumin ratio. Methods: A retrospective examination was made of 40 patients diagnosed with idiopathic sudden hearing loss and a control group of 45 healthy subjects. The pure tone averages of all the patients were determined on first presentation and repeated at 3 months after the treatment. The patients were separated into 2 groups according to the response to treatment. The neutrophil/lynphocyte ratio and the C-reactive protein/albumin ratios were calculated from the laboratory tests. Results: The patients included 16 females and 24 males with a mean age of 44.1 ± 14.2 years and the control group was composed of 23 females and 22 males with a mean age of 42.2 ± 13.8 years. The mean C-reactive protein/albumin ratio was 0.95 ± 0.47 in the patient group and 0.74 ± 0.13 in the control group. The difference was statistically significant (p = 0.009). The mean C-reactive protein/albumin ratio was 0.79 ± 0.12 in the response to treatment group and 1.27 ± 0.72 in the non-response group, with no significant difference determined between the groups (p = 0.418). The mean neutrophil/lymphocyte ratio was 3.52 ± 3.00 in the response to treatment group and 4.90 ± 4.60 in the non-response group, with no statistically significant difference determined between the groups (p = 0.261). Conclusion: C-reactive/albumin ratio was significantly higher in patients with sudden hearing loss than in the control group. Although C-reactive protein/albumin ratio was found to be lower in sudden hearing loss patients who responded to treatment compared to those who did not, the difference between two groups was not statistically significant.

Resumo Introdução: A perda auditiva neurossensorial súbita ou surdez súbita é uma emergência otológica significativa. Estudos anteriores revelaram uma coexistência dessa condição com inflamação crônica. A importância preditiva dos valores da relação proteína C-reativa/albumina como fator prognóstico tem sido demonstrada em várias condições inflamatórias e tumorais. Objetivos: O objetivo deste estudo foi determinar se a relação proteína C-reativa/albumina na perda auditiva neurossensorial súbita pode ser usada para fins prognósticos e se existe uma associação entre as relações neutrófilo/linfócito e proteína C-reativa/albumina. Método: Foram avaliados retrospectivamente 40 pacientes com diagnóstico de perda auditiva neurossensorial súbita idiopática e um grupo controle de 45 indivíduos saudáveis. As médias de tons puros de todos os pacientes foram determinadas na primeira consulta e repetidas 3 meses após o tratamento. Os pacientes foram separados em 2 grupos de acordo com a resposta ao tratamento. As relações neutrófilo/linfócito e proteína C-reativa/albumina foram calculadas a partir de testes laboratoriais. Resultados: Os pacientes incluíam 16 mulheres e 24 homens, com média de 44,1 ± 14,2 anos, e o grupo controle por 23 mulheres e 22 homens, com média de 42,2 ± 13,8 anos. A média da relação proteína C-reativa/albumina foi de 0,95 ± 0,47 no grupo de pacientes e de 0,74 ± 0,13 no grupo controle e a diferença foi estatisticamente significante (p = 0,009). A média da relação proteína C-reativa/albumina foi de 0,79 ± 0,12 do grupo com resposta ao tratamento e de 1,27 ± 0,72 no grupo sem resposta, sem diferença significante entre os grupos (p = 0,418). A média da relação neutrófilo/linfócito foi de 3,52 ± 3,00 no grupo com resposta ao tratamento e de 4,90 ± 4,60 no grupo sem resposta, sem diferença estatisticamente significativa entre os grupos (p = 0,261). Conclusão: A relação proteína C-reativa/albumina foi significantemente maior nos pacientes com perda auditiva neurossensorial súbita do que no grupo controle. No entanto, embora a relação proteína C-reativa/albumina tenha sido menor nos pacientes com perda auditiva neurossensorial súbita que responderam ao tratamento em comparação a aqueles que não apresentaram resposta, a diferença entre os dois grupos não foi estatisticamente significante.

The objective of this research was to creates a reference interval for C-reactive protein (CRP)/albumin ratio (CAR) in the canine species and to analyze the potential of CRP, albumin and the relationship between both, to serve as indicators of disease severity, length of hospital stay (LoS) and mortality in this species. For this, an outcome study was conducted in a Veterinary Teaching Hospital in southern Brazil. One hundred ninety dogs were included randomly, without distinction of gender, age, or breed, from June 2013 to November 2016. Plasma was collected from them and analyzed for assessment of CRP and albumin. The reference range stipulated for CAR in dogs was 0.36-0.60, as determined by the confidence interval of mean resamplings (in percentiles). The frequencies mean, and standard deviations of the variables, correlation analysis, and comparative analysis (Kruskal-Wallis in α = 5%) were calculated. Elevation (above reference) of CAR was determined to be proportional to the severity of the underlying disease, and CRP means were reasonable. Besides, hypoalbuminemia was indicative of systemic disease, but not of severity. Thus, CAR was a better marker of disease severity than were CRP and albumin, analyzed separately. Concerning LoS, there was a positive correlation with CAR (p<0.01) in patients, and the same was not observed with CRP and albumin. Concerning mortality, hypoalbuminemia was the only marker valid in animals with a critical illness (p=0.04). In conclusion, CAR is a better marker of disease severity and LoS in dogs than are CRP and albumin analyzed separately.(AU)

O objetivo desta pesquisa foi determinar um intervalo de referência para a relação proteína C reativa (PCR)/albumina (R:PCR/ALB) na espécie canina e analisar o potencial de PCR, albumina e a relação entre ambas como indicadores de gravidade de doença, tempo de internação (TI) e mortalidade nesta espécie. Para isso, um estudo foi realizado em um Hospital Veterinário Escola no sul do Brasil. Cento e noventa cães foram incluídos aleatoriamente, sem distinção de sexo, idade ou raça, de junho de 2013 a novembro de 2016. O plasma foi coletado e analisado para avaliação da PCR e albumina. O intervalo de referência estipulado para o R:PCR/ALB em cães foi de 0,36-0,60, conforme determinado pelo intervalo de confiança da média das reamostragens (em percentis). Foram calculadas as frequências, médias e desvios-padrões das variáveis, análises de correlação e análises comparativas (Kruskal-Wallis em α = 5%). Notou-se elevação (acima da referência) da R:PCR/ALB proporcional à gravidade da doença de base, sendo normais as médias da PCR. Adicionalmente, a hipoalbuminemia foi indicadora de doença sistêmica, mas, não de gravidade. Dessa forma, a R:PCR/ALB foi melhor indicadora de gravidade de doença do que a PCR e albumina, analisadas separadamente. Em relação ao TI, houve correlação positiva com a R:PCR/ALB (p<0,01) em doentes, não sendo observado o mesmo com a PCR e albumina. Em relação à mortalidade, a hipoalbuminemia foi a única marcadora válida em animais com doenças críticas (p=0,04). Conclui-se, portanto, que a R:PCR/ALB é melhor marcadora de gravidade de doença e TI em cães do que a PCR e albumina analisadas separadamente.(AU)

Introdução: Pacientes portadores de vasculopatia periférica internam recorrentemente para procedimentos cirúrgicos ou tratamento clínico devido a complicações da doença de base. O real impacto da desnutrição nesses pacientes durante a internação ainda é pouco compreendido. Objetivo: Investigar os fatores de risco associados à mortalidade em pacientes internados com doença vascular periférica devido a complicação da doença vascular. Métodos: Estudo observacional retrospectivo avaliou cento e dezessete pacientes acima de 18 anos admitidos no serviço de cirurgia vascular de hospital terciário no período de junho de 2013 a agosto de 2014 por complicação da doença vascular. Avaliados parâmetros clínicos, comorbidades, dados demográficos, complicações durante a internação e estado nutricional. Dados coletados por meio de entrevista, aplicação do questionário Avaliação Global Subjetiva (AGS), exame físico e laboratoriais e dados de prontuário. Resultados: Cento e dezessete pacientes com doença vascular periférica avaliados em relação a complicações vasculares durante internação. Mortalidade geral de 7,7% e pacientes desnutridos ou com suspeita de desnutrição eram 39% da amostra Através da análise multivariada, tanto a classificação AGS (OR 6,15 CI 1,092-34,74 P = 0,039) quanto a presença de doença cardíaca (OR 8,51 CI 1,56-47,44 P = 0,015) foram fatores preditores independentes para mortalidade. Pacientes com doença vascular classificados em suspeita de estarem desnutridos ou desnutridos apresentaram chance de ir a óbito durante a internação aumentada em 6,15 vezes, enquanto a cardiopatia elevou essa chance 8,51 vezes. Conclusão: Pacientes internados por complicação de doença vascular periférica apresentam como fatores de risco para mortalidade a desnutrição e a presença de doença cardíaca.(AU)

Patients with peripheral vasculopathy are routinely hospitalized for surgical procedures or clinical treatment due to complications of the underlying disease. The real impact of malnutrition in these patients during hospitalization is still poorly understood. Aim: This study aimed to assess mortality predictors in patients with peripheral vascular disease during hospitalization. Methods: This retrospective observational study evaluate one hundred and seventeen patients over 18 years admitted to the vascular surgery service of a tertiary hospital in the period of June 2013 and August 2014 due to complications of vascular disease. They were assessed for clinical parameters, comorbidities, demographics, complications during hospitalization and nutritional status. Data were collected through interviews, the questionnaire Subjective Global Nutritional Assessment (SGA), laboratory exam and physical examination. Results: One hundred and seventeen patients with peripheral vascular disease were followed during admission due to vascular complications. Overall mortality was 7.7%, and malnourished patients or patients at nutritional risk were 39,0% of the sampled population By multivariate analysis both rating by SGA (OR 6.15, CI 1.092 to 34.74, P = 0.039), the presence of heart disease (OR 8.51 CI 1,56 to 47.44 P = 0.015) were independent predictors of mortality. When the patient was classified as malnourished or suspected of being malnourished by SGA it increased 6.15 times the odds of death during hospitalization, while the presence of heart disease increased by 8.51 times. Conclusion: Patients hospitalized for complications of peripheral vascular disease present as risk factors for mortality: malnutrition and the presence of heart disease. (AU)

RESUMEN El médico asistencial debe evaluar a diario las pruebas hepáticas en personas con afecciones del hígado, o en los llamados controles a personas supuestamente normales. El objetivo fue facilitar la reflexión práctica en la interpretación de las pruebas hepáticas. Se realizó una revisión de las publicaciones más importantes en base de datos como MEDLINE, EMBASE y Scielo en los últimos años para facilitar la interpretación de las pruebas de laboratorio en el estudio de las lesiones del hígado. En la práctica diaria la elevación de las aminotransferasas, ha sido asociada con un incremento en la mortalidad total y está relacionada con disfunción hepática. Los estudios imagenológicos al igual que la biopsia hepática pueden ser considerados cuando las pruebas hepáticas no definen el diagnóstico, para estudiar al enfermo o cuando los posibles diagnósticos sean múltiples, por lo que definir el valor de la elevación de los niveles de alanino aminotransferasas, aspartato aminotransferasas, junto a la los niveles de fosfatasa alcalina y bilirrubina en la lesión colestática, unidas al uso de pruebas que miden el metabolismo celular en la enfermedad hepatocelular o la colestasis son de vital importancia la práctica médica diaria (AU).

SUMMARY The physician providing health care should daily evaluate hepatic testes in persons with liver diseases, or in the so-called controls to persons supposedly healthy. The aim of this work was facilitating practical reflection in the interpretation of hepatic testes. The most important works published in MEDLINE, EMBASE and Scielo during the last years were reviewed for understanding laboratory tests in the study of hepatic lesions. In the regular practice the increase of aminotransferases has been associated to a growth of total mortality, and this one related to hepatic dysfunction. The imaging studies and also hepatic biopsy should be taking into consideration when hepatic testes do not define the diagnosis, to study the patient, or when there are many possible diagnoses; therefore defining the growth of the alaninotransferase and aspartate aminotransferase levels together with the levels of alkaline phosphatase and bilirubin in the cholestasis lesion and the use of testes measuring the cell metabolism in the hepatocellular disease or cholestasis are very important in the day-to-day medical practice (AU).

Abstract Objective: To investigate the effect of continuous lung ventilation with low tidal volume on oxidation parameters, such as thiol/disulphide homeostasis and albumin-adjusted ischemia-modified albumin (AAIMA), during cardiopulmonary bypass (CBP) in coronary artery bypass grafting (CABG). Methods: Seventy-four patients who underwent elective CABG with CPB were included in the study. Blood samples were taken in the preoperative period, 10 minutes after CPB, and six and 24 hours postoperatively. Patients were assigned to the continuous ventilation group (Group 1, n=37) and the non-ventilated group (Group 2, n=37). The clinical characteristics, thiol/disulphide homeostasis, ischemia-modified albumin (IMA), and AAIMA levels of the patients were compared. Results: A significant difference was found between the groups regarding native thiol, total thiol, and IMA levels at the postoperative 24th hour (P=0.030, P=0.031, and P=0.004, respectively). There was no difference between the groups in terms of AAIMA. AAIMA levels returned to preoperative levels in Groups 1 and 2, at the 6th and 24th postoperative hours, respectively. Length of hospital stay was significantly shorter in Group 1 (P<0.001) than in Group 2. Conclusion: Continuous ventilation during CPB caused an increase in native and total thiol levels, an earlier return of AAIMA levels, and shorter hospital stay. Continuous ventilation may reduce the negative effects of CPB on myocardium (Table 2, Figure 1, and Reference 31).

ABSTRACT Objectives: To investigate whether Glasgow Prognostic Score has prognostic significance in patients with upper urinary urothelial carcinoma. Patients and methods: We retrospectively reviewed the clinical records of 74 patients with upper urinary urothelial carcinoma. We set the cut-off value for C-reactive protein as 1.0mg/dL, and 3.5mg/dL for albumin as Glasgow Prognostic Score. Their blood data including albumin and C-reactive protein for Glasgow Prognostic Score and cytokeratin 19 fragment 21-1 as a tumor marker were measured before starting treatment. The patients were stratified into three groups with Glasgow Prognostic Score: The Group-1, albumin ≥3.5g/dL and C-reactive protein < 1.0mg/dL; Group-2, albumin < 3.5g/dL or C-reactive protein ≥1.0mg/dL; Group-3, albumin < 3.5g/dL and C-reactive protein ≥1.0mg/dL. Results: The median follow-up for all patients was 26.9 months (range: 10.9-91.1 months), during which 37 (50%) patients died. There was a significant difference in the estimated survival rate among the 3 groups stratified by Glasgow Prognostic Score. The estimated survival rate in the Group-1 was significantly higher than those in Groups 2 and 3. In the univariate analysis C-reactive protein, serum cytokeratin 19 fragment 21-1 and Glasgow Prognostic Score were significant predictors of overall survival. On the multivariate analysis, serum cytokeratin 19 fragment 21-1 and Glasgow Prognostic Score were independently associated with shorter overall survival. Conclusion: Our review suggests Glasgow Prognostic Score may play as a prognostic predictor for upper urinary urothelial carcinoma.

The aim of this study to measure the fractions of the total serum proteins of the Campeiro horse and identify the influences of biological variants. Blood samples were taken in 138 horses of the breed Campeiro for measuring the concentration of total serum protein by the biuret method. Serum concentrations of protein fractions were measured by electrophoresis using agarose gel. Groups were formed according to age, sex and reproductive condition. The average values of serum fractions: albumin (2.85±0.36g/dl), alpha 1 (0.28±0.11g/dl), alpha 2 (0.26±0.08g/dL) beta 1 (0.57±0.15g/dl), beta 2 (0.89±0.28g/dL), gamaglobulinas (1.86±0.34g/dL), albumin/globulin ratio (0.75±0.18) and 2.5% percentile and 97.5% had slight differences in relation to the reference interval proposed for the species. They observed higher values of alpha 1 and 2 globulins in the group from that had six to eight years old and gammaglobulins in group above 13 years old. Serum protein concentrations were similar in horses and mares and between non-pregnant and pregnant. Sex and pregnancy status did not affect serum proteinogram. Alpha and gammaglobulins have higher values as the age increases. Serum proteinogram of Campeiro horses shows variations that have to be considered in the interpretation of laboratory tests.(AU)

Este trabalho tem por objetivo mensurar as frações das proteínas totais séricas de equinos Campeiros e identificar as influências de variantes biológicas. Foram colhidas amostras de sangue de 138 equinos, machos e fêmeas da raça Campeiro. A determinação da concentração de proteínas totais séricas foi realizada pelo método de biureto. As concentrações séricas das frações proteicas foram determinadas por eletroforese, utilizando-se gel de agarose. Formaram-se grupos em relação à idade, ao sexo e à condição reprodutiva. Os valores médios das frações séricas albumina (2,85±0,36g/dL), alfa 1 (0,28±0,11g/dL), alfa 2 (0,26±0,08g/dL), beta 1 (0,57±0,15g/dL), beta 2 (0,89±0,28g/dL), gamaglobulinas (1,86±0,34g/dL), relação albumina/globulina (0,75±0,18) e os percentis 2,5% e 97,5% apresentaram diferenças pontuais em relação aos intervalos propostos para a espécie. Observaram-se maiores valores de alfa 1, alfa 2 globulinas, no grupo de seis a oito anos, e de gamaglobulinas, no grupo acima de 13 anos de idade. O proteinograma sérico foi similar entre machos e fêmeas e entre fêmeas vazias e gestantes. Sexo e estado gestacional não afetaram o proteinograma sérico. Alfa e gamaglobulinas têm incrementos em função de idades crescentes. O proteinograma sérico de equinos Campeiros tem variações que devem ser consideradas em exames laboratoriais.(AU)

Abstract BACKGROUND: Tacrolimus, for its activity on modulation of collagen production and fibroblast activity, may have a role in the prevention of hypertrophic scars. OBJECTIVES: Evaluate macroscopic, microscopic, metabolic, laboratory effects and side effects of the use of topical tacrolimus ointment, in different concentrations, in the prevention of hypertrophic scars. METHODS: Twenty-two rabbits were submitted to the excision of 2 fragments of 1 cm of each ear, 4 cm apart, down to cartilage. The left ear of the animals was standardized as control and Vaseline applied twice a day. The right ear received tacrolimus ointment, at concentrations of 0.1% on the upper wound and 0.03% on the lower wound, also applied twice a day. Macroscopic, microscopic, laboratory criteria and the animals' weight were evaluated after 30 days of the experiment. RESULTS: Wounds treated with tacrolimus, at concentrations of 0.1% and 0.03%, when compared to control, showed a lower average degree of thickening (p = 0.048 and p <0.001, respectively). The average of scar thickness and lymphocyte, neutrophil and eosinophil concentrations are lower in the treated wounds compared to the control (p <0.001, p=0.022, p=0.007, p=0.044, respectively). The mean concentration of lymphocytes is lower in wounds treated with a higher concentration of the drug (p=0.01). STUDY LIMITATIONS: experiment lasted only 30 days. CONCLUSIONS: Tacrolimus at the 2 concentrations evaluated reduced the severity of inflammatory changes and positively altered the macroscopic aspect of the scar in the short term. Its use was shown to be safe, with no evidence of systemic or local adverse effects.

Resumo A desnutrição é um fator relevante na evolução dos pacientes com doença renal crônica (DRC) em hemodiálise (HD), estando associada a maior frequência e duração de internações hospitalares. Objetivou-se avaliar o estado nutricional de pacientes com DRC em HD em unidades públicas ou privadas vinculadas ao SUS no Distrito Federal. Dados sociodemográficos, bioquímicos e antropométricos foram obtidos de 96 participantes, sendo 35,5% provenientes de hospitais públicos. Os critérios utilizados para avaliação de desnutrição na DRC foram Índice de Massa Corpórea (IMC) < 23 kg/m2, circunferência muscular do braço (CMB) reduzida e albumina sérica < 3,8 g/dl. Do total de avaliados, 14,6% apresentou desnutrição (60 ± 12 anos; 57% masculino; 69% clínicas privadas); 33,3% apresentou estado nutricional adequado (55 ± 14 anos; 53% masculino; 57% clínicas privadas); 52,1% tinha ao menos uma variável relacionada à desnutrição, onde o IMC abaixo do recomendado foi o mais prevalente (42,7%), seguido da CMB reduzida (41,7%) e da albumina sérica (33,3%). Com base nos resultados conclui-se que ao menos uma variável relacionada ao estado nutricional esteve alterada em metade da amostra estudada, o que reforça a importância da avaliação nutricional no contexto do tratamento da DRC.

Abstract Malnutrition is a major factor in the evolution of patients with chronic kidney disease (CKD) on hemodialysis (HD). It is associated with increased frequency and the duration of hospitalizations. The scope of this study was to evaluate the nutritional status of patients with CKD on HD in public or private clinics of the Unified Health System in the Federal District. Sociodemographic, biochemical and anthropometric data were obtained from 96 participants, 35.5% of which were from public clinics. Parameters for evaluation of malnutrition in CKD included Body Mass Index (BMI) < 23 kg/m2, reduced arm muscle circumference (AMC) and serum albumin < 3.8 g/dL. From all participants, 14.6% were classified as malnourished (60 ± 12 years; 57% male; 69% private clinics); 33.3% presented adequate nutritional status (55 ± 14 years; 53% male; 57% private clinics); 52.1% had at least one parameter related to malnutrition. BMI below the recommended parameter was the most prevalent variable (42.7%), followed by reduced AMC (41.7%) and serum albumin (33.3%). Based on these results, it may be concluded that at least one positive variable was related to malnutrition in half of the sample, which reinforces the importance of nutritional assessment in the context of the treatment of CKD.

Iso-oncotic human serum albumin (HSA) is the primary replacement fluid of choice during therapeutic plasma exchange (TPE). Hypersensitivity reactions to HSA are rare, but require proper evaluation and management. In this article, we report two cases of hypersensitivity reactions to 5% HSA during TPE and discuss strategies to address this problem. The first case was a 60-year-old female patient, who was scheduled for TPE for treatment of recurrent focal segmental glomerulosclerosis after ABO-incompatible kidney transplantation. She developed a pruritic rash on her entire body during the first two sessions of TPE using 5% HSA. The third session was conducted using 500 mL normal saline, 1,000 mL 10% pentastarch, and 750 mL 5% HSA, where she eventually developed a pruritic rash when HSA was infused. There were no adverse events during the fourth and fifth session when fresh frozen plasma was used in place of HSA. The second case was a 50-year-old male patient diagnosed with optic neuritis, who was admitted for five sessions of TPE. The patient developed a pruritic rash on his entire body during the first session of TPE using 5% HSA. The patient experienced no adverse events during the following four sessions using fresh frozen plasma. Certain elements contained in HSA, such as albumin aggregates, prekallikrein activator, and caprylate-modified albumin, might be the reason for these hypersensitivity reactions. Careful selection of alternative replacement fluids is important to avoid premature termination of TPE procedures and secure optimal treatment options for patients.

Approximately 13–20% of infants with milk allergies concurrently exhibit beef allergies. Here, we report a 24-month-old infant who exhibited both pork and beef allergies, concurrently with a milk allergy. The infant's laboratory test results were: 3.73 ISU-E (ISAC standardized unit for IgE) for cow milk β-lactoglobulin, 23.8 ISU-E for casein, 12.8 ISU-E for cow milk Bos d 6 of serum albumin, and 4.85 ISU-E for cat Fel d 2. This case report summarizes an infant patient diagnosed with a meat allergy that was associated with cow's milk allergy, using ImmunoCAP ISAC®. Not only ImmunoCAP ISAC® but also immunocap can be used to diagnose milk allergy and meat allergy at the same time, immunocap testing for component antigen is rare. ImmunoCAP ISAC® is used to diagnose these allergies in our case study, as it has advantage that only 1ml of blood is needed to run various component antigen tests.

PURPOSE: We compared thyroid hormone profiles in children with nephrotic syndrome (NS) during the nephrotic phase and after remission. METHODS: This study included 31 pediatric NS patients. The thyroid hormone profiles included serum levels of triiodothyronine (T3), thyroxine (T4), thyroid-stimulating hormone (TSH), and free T4. RESULTS: Of the 31 patients, 16 (51.6%) showed abnormal thyroid hormone profiles: 6 had overt hypothyroidism, 8 had subclinical hypothyroidism, and 2 had low T3 syndrome. The mean serum T3, T4, and free T4 levels in the nephrotic phase and after remission were 82.37±23.64 and 117.88±29.49 ng/dL, 5.47±1.14 and 7.91±1.56 µg/dL, and 1.02±0.26 and 1.38±0.23 ng/dL, respectively; the levels were significantly lower in the NS nephrotic phase (P=0.0007, P<0.0001, and P=0.0002). The mean serum TSH levels during the nephrotic phase and after remission were 8.05±3.53 and 4.08±2.05 µIU/ mL, respectively; they were significantly higher in the nephrotic phase (P=0.0005). The urinary protein/ creatinine ratio during the nephrotic phase was significantly correlated with serum T3, T4, and free T4 levels (r=-0.5995, P=0.0032; r=-0.5797, P=0.0047; r=-0.5513, P=0.0078) as well as with TSH levels (r=0.5022, P=0.0172). A significant correlation was found between serum albumin and serum T3 levels during the nephrotic phase (r=0.5385, P=0.0018) but not between serum albumin and T4, TSH, or free T4 levels. These significant correlations all disappeared after remission. CONCLUSION: Abnormal thyroid hormone profile findings were observed in 51.6% of pediatric patients with NS. Thyroid hormone levels normalized after remission, regardless of levothyroxine therapy.
