Introduction: Quality Indicators for Nutritional Therapy (QINT) allow a practical assessment of nutritional therapy (NT) quality. Objective: To apply and monitor QINT for critically ill patients at nutritional risk. Methods: Cross sectional study including critically ill patients > 18 years old, at nutritional risk, on exclusive enteral (ENT) or parenteral nutritional therapy (PNT) for > 72 hours. After three consecutive years, 9 QINT were applied and monitored. Statistical analysis was performed with SPSS version 17.0. Results: A total of 145 patients were included, 93 patients were receiving ENT, among then 65% were male and the mean age was 55.7 years (± 17.4); 52 patients were receiving PNT, 67% were male and the mean age was 58.1 years (± 17.4). All patients (ENT and PNT) were nutritionally screened at admission and their energy and protein needs were individually estimated. Only ENT was early initiated, more than 70% of the prescribed ENT volume was infused and there was a reduced withdrawal of enteral feeding tube. The frequency of diarrhea episodes and digestive fasting were not adequate in ENT patients. The proper supply of energy was contemplated only for PNT patients and there was an expressive rate of oral intake recovery in ENT patients. Conclusion: After three years of research, the percentage of QINT adequacy varied between 55%-77% for ENT and 60%-80% for PNT. The results were only made possible by the efforts of a multidisciplinary team and the continuous re-evaluation of the procedures in order to maintain the nutritional assistance for patients at nutritional risk.

Introducción: los indicadores de calidad en terapia nutricional (ICTN) permiten evaluar la calidad de la terapia nutricional (TN) de forma práctica. Objetivo: implementar y monitorizar los ICTN en pacientes críticos con riesgo nutricional. Métodos: estudio transversal con pacientes críticos > 18 años en riesgo nutricional, en terapia nutricional enteral (TNE) o parenteral (TNP) exclusiva a > 72 horas. Después de 3 años consecutivos, 9 ICTN fueron implementados y monitorizados. El análisis estadístico fue realizado con el software SPSS, versión 17.0. Resultados: fueron incluidos 145 pacientes, siendo 93 en TNE, 65% eran de sexo masculino, con edad promedio de 55,7 años (± 17,4); 52 pacientes que estaban en TNP, 67% eran de sexo masculino, con edad promedio de 58,1 años (± 17,4). Todos los pacientes (TNE y TNP) fueron cribados en la admisión, los cálculos de las necesidades calóricas y proteínicas fueron individualizados. Apenas la TNE fue precoz, > 70% del volumen prescrito fue administrado y fue visto una reducida pérdida de la sonda nasoenteral. Las frecuencias de diarrea y ayuno digestivo no fueron adecuadas en TNE. La administración adecuada de energía fue contemplada apenas en TNP y hubo una significativa tendencia de recuperación en la vía oral en TNE. Conclusión: después de 3 años de estudio, el porcentaje de adecuación de los ICTN varió entre 55%-77% para TNE y 60%-80% para TNP. Los resultados reflejan los esfuerzos del equipo multiprofesional de TN en mantener la calidad de la asistencia nutricional en los pacientes críticos con riesgo nutricional.

Abstract Objective: To evaluate heart rate variability during an inspiratory muscle endurance protocol at three different load levels [30%, 60% and 80% of maximal inspiratory pressure], in patients who had previously undergone coronary artery bypass grafting. Methods: Nineteen late postoperative myocardial revascularization patients participating in a cardiovascular rehabilitation program were studied. Maximal inspiratory pressure maneuvers were performed. An inspiratory muscle endurance protocol at 30%, 60% and 80% of maximal inspiratory pressure was applied for four minutes each, in random order. Heart rate and RR intervals were recorded and heart rate variability was analyzed by time (RMSSD-the mean of the standard deviations for all R-R intervals, and RMSM-root-mean square differences of successive R-R intervals) and frequency domains indices (high and low frequency) in normalized units. ANOVA for repeated measurements was used to compare heart rate variability indices and Student t-test was used to compare the maximal inspiratory pressure and maximal expiratory pressure values. Results: Heart rate increased during performance of maximal respiratory pressures maneuvers, and the maximal inspiratory pressure and maximal expiratory pressure mean values were significantly lower than predicted values (P <0.05). RMSSD increased significantly at 80% in relation to rest and 30% of maximal inspiratory pressure and RMSM decreased at 30% and 60% of maximal inspiratory pressure in relation to rest (P <0.05). Additionally, there was significant and progressive decrease in low frequency and increase in high frequency at 30%, 60% and 80% of maximal inspiratory pressure in relation to the resting condition. Conclusion: These results suggest that respiratory muscle training at high intensities can promote greater parasympathetic activity and it may confer important benefits during a rehabilitation program in post-coronary artery bypass grafting.

Introduction: the inflammatory response caused by sepsis leads to metabolic changes, which may result in significant lean mass loss in septic patient. Because of this, when digestive tract is functional, nutritional therapy (NT) must be initiated within 48 hours of intensive treatment to reduce protein loss. Objective: to evaluate enteral nutritional therapy (ENT) in adult septic patients with exclusive ENT for ≥ 72 hours and length of stay ≥ 7 days in Intensive Care Unit and its relationship with clinical prognosis. Methods: we prospectively analyzed the adequacy of enteral nutrition administered, factors associated with non-conformity, gastrointestinal tolerance and outcome. Statistical tests of chi-square and Student�fs t as well as Mann-Whitney and Spearman and Pearson correlations (p < 0.05) were used. A multiple logistic regression model has been done by using the stepwise method to evaluate the association between predictors of clinical outcome. Results: 53 patients, 67.9% male and 52.8% elderly were enrolled in this study. The average time for starting ENT was 30 (23.5) hours, and 88.7% of patients achieved nutritional goal in 48 hours. The mean volume delivered in relation to prescribed was 78.9%. When the sample was stratified according to administered/ prescribed calories, patients who received < 80% had a higher mortality rate (p = 0.001) and the caloric intake . 80% was the determining factor in patients�f clinical prognosis (p = 0.021). Conclusion: septic patients received early enteral nutrition. The nutritional goal and the mean volume delivered in relation to the prescribed volume meet the intensive care guidelines. The nutritional support was associated with clinical outcome, and caloric intake ≥ 80% determining the clinical prognosis. The pauses caused by reflux were significant in the group of patients who died and it may be related to disease severity.

Introducción: la respuesta inflamatoria causada por sepsis provoca cambios metabólicos que pueden provocar una perdida de masa magra significativa en pacientes sépticos. Debido a ello, cuando el tracto digestivo es funcional la terapia nutricional (NT) debe iniciarse dentro de las 48 horas de tratamiento intensivo para reducir la perdida de proteína. Objetivo: evaluar la terapia nutricional enteral (TNE) en pacientes sépticos adultos con TNE exclusivo para ≥ 72 horas y duración de ≥ 7 días de estancia en la Unidad de Cuidados Intensivos y su relación con el pronostico clínico. Métodos: se analizaron prospectivamente la adecuación de la nutrición enteral administrada, los factores asociados con la falta de conformidad, la tolerancia gastrointestinal y el resultado. Se utilizaron pruebas estadísticas de chi-cuadrado y la t de Student, así como las correlaciones de Mann-Whitney y Spearman y Pearson (p < 0,05). Se ha realizado un modelo de regresión logística múltiple mediante el método paso a paso para evaluar la asociacion entre factores de predicción de la evolución clínica. Resultados: 53 pacientes, 67,9% hombres y 52,8% ancianos se inscribieron en este estudio. El tiempo promedio para el inicio de ENT fue de 30 (23,5) horas, y el 88,7% de los pacientes alcanzaron el objetivo nutricional en 48 horas. El volumen medio entregado en relación con el prescrito fue 78,9%. Cuando la muestra se estratifico según calorías prescritas/administradas, los pacientes que recibieron < 80% tenían una tasa de mortalidad mas alta (p = 0,001) y el consumo de calorías . 80% fue el factor determinante en el pronostico clínico de los pacientes (p = 0,021). Conclusión: los pacientes sépticos recibieron nutrición enteral precoz. El objetivo nutricional y el volumen medio entregado en relación con el volumen prescrito cumplen las directrices de cuidados intensivos. El soporte nutricional se asocio con el resultado clínico y la ingesta calórica ≥ 80% para determinar el pronostico clínico. Las pausas causadas por el reflujo fueron significativas en el grupo de pacientes que murieron y que pueden estar relacionadas con la gravedad de la enfermedad.

ResumoA cidade de Montevidéu, com mais de 1,5 milhões de habitantes, circunda a Baía de Montevidéu, onde um dos portos mais ativos e poluídos da América do Sul está localizado. No presente trabalho, foram avaliados esteróis fecais, metais traço, compostos organoclorados e derivados de petróleo nos sedimentos superficiais do Porto de Montevidéu, analisando sua distribuição espacial no interior do porto, bem como em dois dos principais tributários que chegam ao interior da baía. Especificamente para os sítios do porto, foi realizada uma comparação temporal dos metais pesados e hidrocarbonetos, considerando dados pretéritos de 12 anos. Foram observadas alterações significativas nos sítios estudados. Metais, tais como o Pb, Cr e Zn, apresentaram redução nas suas concentrações, enquanto os hidrocarbonetos alifáticos aumentaram seus valores em quase todas as estações. Foram observadas também diferenças entre o verão e o inverno, sugerindo mudanças no padrão de sedimentação, nos ingressos de substâncias e/ou mudanças hidrodinâmicas na área. Os resultados podem vir auxiliar na compreensão do estado atual e para o desenvolvimento de medidas de gestão necessárias para melhorar a qualidade ambiental do porto e da baía.

AbstractSituated opposite the Freshwater Front, Montevideo city with its more than 1.5 million inhabitants encircles Montevideo Bay, where one of the most active and polluted harbors in South America is located. Faecal sterols, trace metals, organochlorine compounds and petroleum derivatives in the sediments of Montevideo Harbor were evaluated and their spatial distribution inside the harbor as well as in the input of two main tributary streams analyzed. Specifically for the harbor sites, a temporal comparison of metal and hydrocarbons was made with previous measurements taken 12 years ago. Clear changes were observed at these sites. The concentration of metals such as Pb, Cr and Zn have diminished, while aliphatic hydrocarbons have increased their values at almost all of the stations studied. Differences were observed between summer and winter suggesting sedimentation, input or hydrodynamic changes in the area. These results help one to understand the present situation and develop the management measures needed to improve the environmental quality of the harbor and bay.

Objetivo: Determinar os fatores que influenciam na adequação da terapia nutricional enteral em uma unidade de terapia intensiva. Métodos: Estudo prospectivo e observacional realizado em uma unidade de terapia intensiva entre 2010 e 2012. Foram incluídos pacientes >18 anos em terapia nutricional enteral exclusiva por ≥72 horas. As necessidades de energia e proteínas foram calculadas segundo protocolo da unidade. Foram coletados diariamente dados relacionados à nutrição enteral, causas de não conformidade e exames bioquímicos. Resultados: Dentre os pacientes internados na unidade, 93 foram avaliados, 82% iniciaram a terapia nutricional enteral precocemente e 80% atingiram a meta nutricional em <36 horas. Foram administrados 81,6% (±15,4) de volume de terapia nutricional enteral, com adequação de 82,2% (±16,0) de calorias, 82,2% (±15,9) de proteínas e balanço energético médio de -289,9 kcal/dia (±277,1). Houve correlação negativa da proteína C-reativa com o volume administrado e os balanços energético e proteico, e correlação positiva com o tempo para atingir a meta nutricional. A pausa para extubação foi a principal causa de interrupções (29,9% das horas de pausa) e os pacientes >60 anos apresentaram menor porcentagem de recuperação da via oral em relação aos mais jovens (p=0,014). Conclusão: O início precoce da terapia nutricional enteral, e a adequação do volume administrado, de energia e de proteínas estiveram de acordo com as diretrizes. A inadequação dos balanços energético e proteico parece estar associada à resposta inflamatória aguda (proteína C-reativa elevada). A principal causa de interrupção da oferta da terapia nutricional foi a pausa para extubação.

Objective: To determine the factors that influence the adequacy of enteral nutritional therapy in an intensive care unit. Methods: This prospective observational study was conducted in an intensive care unit between 2010 and 2012. Patients >18 years of age underwent exclusive enteral nutritional therapy for ≥72 hours. The energy and protein requirements were calculated according to the ICU protocols. The data regarding enteral nutrition, the causes of non-compliance, and the biochemical test results were collected daily. Results: Ninety-three patients admitted to the intensive care unit were evaluated. Among these patients, 82% underwent early enteral nutritional therapy, and 80% reached the nutritional goal in <36 hours. In addition, 81.6%±15.4% of the enteral nutrition volume was infused, with an adequacy of 82.2%±16.0% for calories, 82.2%±15.9% for proteins, and a mean energy balance of -289.9±277.1kcal/day. A negative correlation of C-reactive protein with the volume infused and the energy and protein balance was observed. In contrast, a positive correlation was found between C-reactive protein and the time required to reach nutritional goals. Extubation was the main cause for interrupting the enteral nutritional therapy (29.9% of the interruption hours), and the patients >60 years of age exhibited a lower percentage of recovery of the oral route compared with the younger patients (p=0.014). Conclusion: Early enteral nutritional therapy and the adequacy for both energy and protein of the nutritional volume infused were in accordance with the established guidelines. Possible inadequacies of energy and protein balance appeared to be associated with an acute inflammatory response, which was characterized by elevated C-reactive protein levels. The main cause of interruption of the enteral nutritional therapy was the time spent in extubation.

Este estudo teve como objetivo verificar a eficiência do uso de imunoestimulante associado a anti-helmíntico no tratamento das helmintoses de ovinos. Os animais do grupo I (n=29) receberam o anti-helmíntico albendazole (11mg kg-1) em administração única e o imunoestimulante composto de Propionibacterium granulosum (16ug kg-1) e lipopolissacarídeo (LPS) de Escherichia coli (1,2ug kg-1) em duas doses com intervalo de 48 horas e os animais do grupo II (n=29) receberam o anti-helmíntico albendazole (11mg kg-1). Amostras foram colhidas semanalmente durante 28 dias para a realização da contagem total e diferencial de leucócitos, hematócrito e contagem de ovos por grama de fezes (OPG). Os animais que receberam imunoestimulante associado a anti-helmíntico apresentaram aumento significativo dos valores de eosinófilos e linfócitos (P<0,05) em relação aos animais que receberam somente anti-helmíntico. Na contagem de ovos por grama de fezes (OPG), não foram observadas diferenças significativas entre os grupos (P>0,05). Com base nesses resultados, pode-se concluir que imunoestimulantes podem ser utilizados associados a anti-helmínticos como alternativa terapêutica no tratamento das helmintíases em ovinos, uma vez que promovem a ativação da resposta imune com participação de células e mediadores importantes para a eliminação de helmintos em ovinos.

This study aimed to verify the effectiveness of the immunostimulant combined with anthelmintic on the helminthiasis treatment in sheep. The animals of group I (n=29) received the anthelmintic albendazole (11mg kg-1) in a single administration and the immunostimulant composed with Propionibacterium granulosum (16ug kg-1) and lypopolysaccharide (LPS) of Escherichia coli (1,2ug kg-1) into two doses every 48 hours and the animals from group II (n=29) received anthelmintic albendazole (11mg g-1). Samples were collected weekly during 28 days, to carry out the total and differential count of leukocytes, hematocrit and the eggs count per gram of feces (EPG). The animals that received immunostimulant combined with anthelmintic showed significantly increases of eosinophils and lymphocytes (P<0.05) compared to animals that only received the anthelmintic. In eggs count per gram of feces (EPG), there were no significant differences between groups (P>0.05). Based on these results it was concluded that immunostimulants can be used when combined with anthelminthic as an alternative therapy for the treatment of helminthiasis in sheep, since they promote the activation of immune response with participation of cells and mediators important for the removal of helminths in sheep.

OBJETIVO: Investigar a relação entre adequação da oferta energética e mortalidade na unidade de terapia intensiva em pacientes sob terapia nutricional enteral exclusiva. MÉTODOS: Estudo observacional prospectivo conduzido em uma unidade de terapia intensiva em 2008 e 2009. Foram incluídos pacientes >18 anos que receberam terapia nutricional enteral por >72h. A adequação da oferta de energia foi estimada pela razão administrado/prescrito. Para a investigação da relação entre variáveis preditoras (adequação da oferta energética, escore APACHE II, sexo, idade e tempo de permanência na unidade de terapia intensiva e o desfecho mortalidade na unidade de terapia intensiva, utilizou-se o modelo de regressão logística não condicional. RESULTADOS: Foram incluídos 63 pacientes (média 58 anos, mortalidade 27%), 47,6% dos quais receberam mais de 90% da energia prescrita (adequação média 88,2%). O balanço energético médio foi de -190 kcal/dia. Observou-se associação significativa entre ocorrência de óbito e as variáveis idade e tempo de permanência na unidade de terapia intensiva, após a retirada das variáveis adequação da oferta energética, APACHE II e sexo durante o processo de modelagem. CONCLUSÃO: A adequação da oferta energética não influenciou a taxa de mortalidade na unidade de terapia intensiva. Protocolos de infusão de nutrição enteral seguidos criteriosamente, com adequação administrado/prescrito acima de 70%, parecem ser suficientes para não interferirem na mortalidade. Dessa forma, pode-se questionar a obrigatoriedade de atingir índices próximos a 100%, considerando a elevada frequência com que ocorrem interrupções no fornecimento de dieta enteral devido a intolerância gastrointestinal e jejuns para exames e procedimentos. Pesquisas futuras poderão identificar a meta ideal de adequação da oferta energética que resulte em redução significativa de complicações, mortalidade e custos.

OBJECTIVE: To investigate the relationship between adequacy of energy intake and intensive care unit mortality in patients receiving exclusive enteral nutrition therapy. METHODS: Observational and prospective study conducted during 2008 and 2009. Patients above 18 years with exclusive enteral nutrition therapy for at least 72 hours were included. The adequacy of energy intake was estimated by the administered/prescribed ratio. Non-conditional logistic regression was used to assess the relationship between predictive variables (adequacy of energy intake, APACHE II, gender, age, and intensive care unit length of stay) and intensive care unit mortality. RESULTS: Sixty-three patients (mean 58 years, 27% mortality) were included, 47.6% of whom received more than 90% of the energy prescribed (mean adequacy 88.2%). Mean energy balance was -190 kcal/day. Significant associations between death in the intensive care unit and the variables age and intensive care unit length of stay were observed, after removing the variables adequacy of energy intake, APACHE II, gender and age during the modeling process. CONCLUSION: In our study, adequacy of energy intake did not affect intensive care unit mortality. Carefully followed enteral nutrition protocols, resulting in an administered/prescribed ratio above 70%, are apparently not sufficient to impact the mortality rates in the intensive care unit. Therefore, it may not be necessary to achieve 100% of the targeted energy, considering the high frequency of enteral feeding interruptions due to gastrointestinal intolerance and fasting for tests and procedures. Additional research is needed to identify the optimal energy intake for improved outcomes and reduced costs.

Os frutos do açaizeiro (Euterpe precatoria Mart.) procedentes de diferentes ecossistemas amazônicos foram processados para a obtenção de suco. O produto foi avaliado quanto à composição centesimal (umidade, cinzas, lipídeos, proteína, glicídios e fibra alimentar), minerais, ácidos graxos e antocianinas. Os frutos foram comparados quanto ao peso, constatando-se uma variação significativa de 1,1 a 2,0 g entre eles. Com relação ao suco, verificou-se baixa concentração de proteína e alto teor de energia devido, principalmente, à presença de lipídeos cuja concentração variou de 4,24 a 9,74%. Dentre os minerais, o potássio foi o mais abundante com teores na faixa de 73,78 a 376,69 mg 100 g-¹ (do suco), seguido do cálcio (15,99 a 57,85 mg 100g-¹). O ferro foi encontrado em concentrações minoritárias, na ordem de 0,43 a 1,2 mg 100g-¹. Com relação aos ingredientes funcionais, o suco de açaí apresentou concentrações importantes de fibra alimentar (2,37 a 7,8%), e antocianinas, variando de 128,4 mg 100 g-¹ , nos frutos de coloração verde, procedentes de Parintins, até 868,9 mg 100 g-¹ nas amostras de Manaquiri (base seca). Na fração lipídica, destacou-se ainda a presença do ácido graxo oleico (18:1), com porcentagem média de 68,2% no total de ácidos graxos, seguido do ácido palmítico (16:0) com 17,5%. Tais resultados reforçam o potencial do açaí como fonte de energia, lipídeos, fibra alimentar, antocianinas, ácido graxo monoinsaturado e minerais. O presente estudo irá contribuir para a ampliação da tabela de composição química de alimentos e, consequentemente, auxiliar nos programas de melhoramento genético, mercado e inclusão social.

The fruit of açaí (Euterpe precatoria Mart.) from different Amazon ecosystems were processed to obtain the juice. The juice obtained from each ecosystem was evaluated for proximate composition (moisture, ash, lipids, protein, carbohydrates and dietary fiber), minerals, fatty acids and anthocyanins. The fruits prior to processing were compared in terms of weight, having noticed a significant variation from 1.1 to 2.0 g. Concerning to the juice, there was a low concentration of protein and high in energy, mainly due to the presence of lipids with a range from 4.24 to 9.74%. Among the minerals, potassium was the most abundant ranging from 73.78 to 376.69 mg 100 g-¹ (per of juice), followed by calcium (from 15.99 to 57.85 mg 100g-¹.). Iron presented minority concentrations from 0.43 to 1.2 mg 100g-¹. With regard to functional ingredients, the acai juice showed significant concentrations of dietary fiber (2.37 to 7.8%), anthocyanins, ranging from 128.4 mg 100 g-¹ in fruits of green color coming from Parintins to 868.9 mg 100 g-¹ in samples of Manaquiri (dry basis). The lipid fraction showed high quantities of oleic fatty acid (18:1), with average percentage of 68.2% in total fatty acids, followed by palmitic acid (16:0) with 17.5%. These results reinforce the potential of acaí as a source of energy, fat, dietary fiber, anthocyanins, monounsaturated fatty acid and mineral elements. The present study will contribute to the expansion of table food composition and to aid in the genetic improvement program, market and social inclusion.

This is the case of a white female patient aged 2, assessed in its origin province due to presence of cutaneous nodules of multiple localizations in lower limbs and in abdomen, referred to "Juan Manuel Márquez" Children Hospital. Lower limbs X-rays showed soft tissues calcifications and a biopsy confirmed the presence of calcified subepidermal nodules. In anamnesis there were neither traumata backgrounds in the area nor consumption of drugs rich in calcium and phosphorus. The physical examination was normal except the above mentioned lesions. Studies to determine some underlying disease that could justify this clinical picture were conducted but without obvious causes. Since the cutaneous Calcinosis is not secondary to systemic affections and there is not metabolic alterations or of other type, diagnosis con idiopathic localized cutaneous calcinosis was made.

Se presenta el caso de un paciente de 2 años de edad, de la raza blanca, sexo femenino, que fue valorada en su provincia de procedencia por presentar nódulos cutáneos de localización múltiple en los miembros inferiores y abdomen, y fue remitida al Hospital Pediátrico «Juan M. Márquez». En las radiografías de las extremidades inferiores se observaron calcificaciones en partes blandas y la biopsia informó nódulos subepidérmicos calcificados. En la anamnesis no se encontraron antecedentes de traumatismos en la zona ni de consumo de fármacos ricos en calcio o fósforo. La exploración física fue normal, salvo las lesiones previamente descritas. Se realizaron estudios para determinar alguna enfermedad subyacente que pudiera justificar este cuadro clínico, pero no se constataron causas evidentes. Dado que la calcicosis cutánea de la paciente no es secundaria a afecciones sistémicas, ni se evidencian alteraciones metabólicas ni de otro tipo, se estableció el diagnóstico de calcinosis cutánea localizada idiopática.

OBJETIVOS: Monitorar a adequação da terapia nutricional enteral na unidade de terapia intensiva visando à melhoria da qualidade da assistência nutricional. MÉTODOS: Estudo prospectivo e observacional desenvolvido na unidade de terapia intensiva adulto entre 2005 e 2008. Participaram da amostra pacientes maiores de 18 anos com terapia nutricional enteral exclusiva por mais de 72h. Analisou-se os valores médios e a adequação percentual de energia e proteínas calculados, prescritos e administrados em cada ano. Os fatores responsáveis pela não conformidade na administração planejada foram classificados em causas externas ou internas à unidade de terapia intensiva. Foram aplicados os indicadores de qualidade propostos pelo International Life Sciences Institute (ILSI) Brasil, sendo expressos em metas percentuais. Nas análises estatísticas utilizou-se o intervalo de confiança e os testes t Student e Mann-Whitney (p<0,05), segundo o programa Epi Info. RESULTADOS: Foram acompanhados 116 pacientes. Os valores médios de energia e proteínas administrados em 2005 e em 2006 apresentaram diferenças estatísticas quando comparados a 2008. A adequação calculado/prescrito permaneceu próxima a 100% em todos os levantamentos e a adequação administrado/prescrito aumentou de 74% em 2005, para 89% em 2008. Constatou-se o aumento nas interrupções da terapia nutricional enteral por fatores externos e a diminuição das interrupções por fatores internos à unidade. Os indicadores de qualidade igualmente refletem a evolução da assistência prestada. CONCLUSÃO: Nos quatro levantamentos anuais verificou-se a melhora progressiva da oferta nutricional. Os indicadores de qualidade são uma nova perspectiva na avaliação da terapia nutricional enteral, permitindo monitorar a evolução da qualidade da assistência nutricional e a comparação com dados de outros serviços.

OBJECTIVE: Monitor the adequacy of enteral nutritional therapy at the intensive care unit aiming to improve the quality of nutritional assistance. METHODS: Prospective and observational study developed at the adult intensive care unit from 2005 to 2008. Patients over 18 years of age with exclusive enteral nutritional therapy for over 72h participated in the sample. The average values and the percentile adequacy of energy and proteins calculated, prescribed and administered in each year were analyzed. The factors responsible for the non-conformity of the administration planned were classified into intensive care unit extrinsic or intrinsic causes. The quality indicators proposed by the ILSI Brazil were applied, and expressed into percentile goals. In the statistic analyses, confidence interval and the t Student e Mann-Whitney (p<0.05) tests were used, according to the Epi Info program. RESULTS: One hundred and sixteen patients were followed up. There were statically difference in values of energy and protein administered in 2005 and in 2006, when compared to those in 2008. The adequacy calculated/prescribed remained close to 100% in all the surveys and the adequacy administered/prescribed increased from 74% in 2005, to 89% in 2008. An increase in interruptions of enteral nutritional therapy for external factors and the decrease in interruptions for intensive care unit internal factors were verified. The quality indicators equally reflect the evolution of the patient care. CONCLUSION: In the four yearly surveys, a progressive enhancement of nutritional support was verified. Quality indicators allow nutritional care evolution monitoring, the comparison to other services data, and are a new perspective for enteral nutritional therapy assessment.

JUSTIFICATIVA E OBJETIVOS: Os pacientes internados em Unidade de Terapia Intensiva (UTI), freqüentemente apresentam depleção nutricional, tornando fundamental a monitoração diária da oferta nutricional. O objetivo desse estudo foi avaliar a adequação da Terapia Nutricional Enteral (TNE) na UTI adulto e identificar as causas de interrupção da administração enteral prescrita. MÉTODO: Foi realizado um estudo observacional prospectivo de pacientes admitidos na UTI recebendo TNE exclusiva, durante 53 dias e infusão da dieta por meio de sistema fechado, infusão contínua (22 horas/dia) e sonda na posição pós-pilórica. A velocidade de administração da dieta iniciada com 25 mL/h e progressão até atingir a meta nutricional conforme protocolo pré-estabelecido. RESULTADOS: Foram acompanhados 33 pacientes com idade entre 18 e 85 anos, 58% do sexo masculino. Os principais diagnósticos de internação foram causas cardiovasculares (27%) e choque séptico (21%). O início da TNE ocorreu em 25,3 ± 20 h após a admissão e atingiu a velocidade de meta nutricional em 32 ± 20,1 h. O volume diário prescrito, estabelecido a partir das necessidades previa atingir 26,1 ± 3,7 kcal/kg e 1,04 g de proteína/kg de peso corporal ± 0,1 g/kg. O volume administrado atingiu 19,5 ± 5,6 kcal/kg e 0,8 g de proteína/kg ± 0,2 g/kg, correspondendo a adequação de 74%. Entre as causas da interrupção na administração da fórmula enteral, a maioria (40,6%) foram para procedimentos de rotina relacionado ao paciente. CONCLUSÕES: Os valores calóricos e protéicos atingidos com TNE neste serviço estão adequados conforme dados da literatura. Estes pacientes apresentaram grave instabilidade clínica interferindo negativamente na tolerância à nutrição enteral. Pode-se constatar que a contínua sistematização de rotinas e treinamento da equipe contribuiu positivamente em atingir os objetivos da terapia nutricional.

BACKGROUND AND OBJECTIVES: In critically ill patients nutritional deficiency is common. Considering this fact, the diary monitoring of energy delivered is extremely important. The objective of this study is to assess the adequacy of enteral nutrition (EN) in an Intensive Care Unit (ICU) and identify the reasons for interruptions in feeding. METHODS: Prospective study of adult patients admitted to ICU in period of 53 days. Patients receiving continuous enteral tube feeding (22 hours/day) exclusively and post-pyloric tube feeding position were followed. The feeding volume started at 25 mL/h and was increased until nutritional goal, guided by a feeding protocol. RESULTS: 33 patients between 18 and 85 years old were studied. 58% were male. The main admission diagnoses were cardiovascular diseases (27%) and septic shock (21%). The mean time to feeding was 25.3 hours after the patient admission and nutritional goal was achieved in a mean time of 32 hours. The total volume prescribed per day was sufficient to guarantee a mean of 26.1 kcal/kg of body weight and 1.04 g of protein/kg of body weight. Patients received a mean of 19.5 kcal/kg of body weight and 0.8 g of protein/kg of body weight, which correspond a 74% of adequacy. Interruptions of feeding for routine procedures related to patients accounted for 40.6% of the total reasons. CONCLUSIONS: The nutritional support is adequate considering the literature for these patients, who clinical instability causes gastrointestinal intolerance. The effective participation of the Nutrition Therapy Team can contribute positively on nutritional therapy.

O controle de qualidade de uma análise laboratorial é essencial para garantir a confiabilidade da informação. Os resultados analíticos serão considerados restritos se não houver um programa definido de controle de qualidade analítico. O presente trabalho propõe modelos esquemáticos para a avaliação da qualidade dos dados nacionais de fibra alimentar. A fibra alimentar foi escolhida, como um modelo, com o propósito de se aplicar os critérios do USDA (U.S. Department of Agriculture) empregados na avaliação do selênio, cobre e de carotenóides. Esta escolha foi baseada na escassez de informações desse nutriente e pela importância da fibra alimentar na prevenção de doenças crônico-degenerativas. Para a avaliação da qualidade dos dados foram consideradas cinco categorias: número de amostras, plano de amostragem, tomada de amostra, método analítico e controle de qualidade analítica. Estes modelos foram utilizados na avaliação da qualidade das determinações de fibra alimentar de 180 alimentos. O resultado obtido foi de 29% com código A e B (considerável e razoável confiança) e 68% com código C (reduzida confiança). Com a determinação da qualidade dos dados, foi possível estabelecer quais os alimentos que constituem prioridades de análise, que são aqueles nos quais ainda não foi determinada a fração fibra alimentar, e aqueles com código de confiança C.

The analytical quality control is essential in order to guarantee the total reliability of the information. Nowadays, the analytical results will be considered restricted if there is not a defined program of quality control. The present paper has in view schematic patterns of evaluation concerned to the quality of national data about dietary fiber. The dietary fiber was chosen as a model with the purpose of applying the USDA (U.S. Department of Agriculture) criteria used for evaluation of selenium, copper and carotenoids. This choice was based on a lack of data about this nutrient, and because dietary fiber plays an important role related to the prevention of chronic diseases. Five categories have been considered for data quality evaluation: number of samples, sampling plan, sample handling, analytical methods and analytical quality control. Results obtained from this evaluation in 180 foods were 29% under code A and B (considerable and reasonable confidence) and 68% under code C (reduced confidence). The analytical quality evaluation of dietary fiber allowed the real assessment of analytical data and helped to establish priority foods for future analysis.

It is described a pulmonary mucormycosis in an 11-year-old child with AIDS. The diagnosis was obtained by direct examination of the bronchial aspiration. The non-septate, hyaline, dichotomous, pathognomonic cenotic hyphae of this disease were observed. The child was cured with the specific treatment with Amphotericin B, since he died a year later and this affection did not appear in the necropsy. This combination of pulmonary mucormycosis and AIDS has never been reported in Cuba.

Se describe una mucormicosis pulmonar en un niño de 11 años de edad con SIDA. El diagnóstico se hizo por examen directo de la aspiración bronquial, observándose las hifas cenocíticas no tabicadas, hialinas, dicotónicas, patognomónicas de esta enfermedad. Con el tratamiento específico de anfotericín B el niño curó, pues 1 año después al fallecer no apareció esta afección en la necropsia. Esta combinación de mucormicosis pulmonar y SIDA no ha sido previamente reportada en Cuba.

25 children of HIV-1 seropositive mothers have been born in Cuba so far. Only 12 (48 %) of them, who are seropositive, have been studied. 4 of them (33,3 %) developed AIDS. Besides, we followed a case who got the disease by a blood transfusion. These children are monthly followed-up at the outpatient department since their birth, and PCR (polymerase chain reaction), ELISA, and Western-Blot for HIV-1 are carried out at 3 and 9 months of age. The diagnostic is confirmed using the some tests at 18 and 36 months of age in order to hnow whether they are carriers or not.

Hasta el momento, han nacido en Cuba 25 niños hijos de madres seropositivas al virus de inmunodeficiencia humana-1 (VIH-1). De estos niños, sólo hemos estudiado 12 (48 %) que son seropositivos, y 4 de estos últimos (33,3 %) desarrollaron el SIDA. Además, seguimos un caso que ha desarrollado esta enfermedad, en el cual la vía de transmisión fue una transfusión sanguínea. Desde su nacimiento, estos niños son seguidos mensualmente en consulta externa, y se les realiza PCR (reacción en cadena polimerasa), ELISA y Western-Blot para VIH-1 a los 3 y 9 meses de edad; y su confirmación diagnóstica se lleva a cabo mediante estas mismas pruebas a los 18 y a los 36 meses de edad, con el fin de conocer si son o no portadores del virus.
