RESUMO Antecedentes: Poucos estudos brasileiros investigaram fatores de risco para disfagia e suas complicações associadas em uma grande coorte. Objetivo: Investigar frequência, preditores e desfechos associados da disfagia em pacientes até três meses após acidente vascular cerebral (AVC). Métodos: Selecionamos pacientes admitidos consecutivamente em um centro especializado em AVC agudo. Excluímos pacientes com ataque isquêmico transitório, hemorragia subaracnóidea, trombose venosa cerebral, AVC hemorrágico de causa secundária, AVC não agudo ou aqueles que não consentiram em participar. A deglutição foi avaliada por fonoaudiólogos, por meio do teste de deglutição de volume-viscosidade. A função geral foi avaliada usando-se escala de Rankin modificada, índice de Barthel e medida de independência funcional. Resultados: Foram admitidos 831 pacientes e incluídos 305. A idade média foi 63,6±13,3 anos, o tempo médio da avaliação foi 4,2±4,1 dias e 45,2% apresentavam disfagia. Idade (razão de chances [OR] 1,02; intervalo de confiança [IC95%] 1,00-1,04; p=0,017), história médica conhecida de apneia obstrutiva do sono (OR=5,13; IC95% 1,74-15,15; p=0,003) e gravidade do AVC na admissão hospitalar (OR=1,10; IC95% 1,06-1,15; p<0,001) foram independentemente associados à disfagia. Disfagia (OR=3,78; IC95% 2,16-6,61; p<0,001) e gravidade do AVC (OR=1,05; IC95% 1,00-1,09; p=0,024) foram independentemente associadas com morte ou dependência funcional em três meses. Conclusões: A disfagia esteve presente em quase metade dos pacientes com AVC. Idade, apneia obstrutiva do sono e gravidade do AVC foram preditores de disfagia, que esteve independentemente associada com morte ou dependência funcional em três meses.

ABSTRACT Background: Few Brazilian studies investigated risk factors for dysphagia and associated complications in a large cohort. Objective: To investigate frequency, predictors, and associated outcomes of dysphagia in patients up to three months post-stroke. Methods: Prospective cohort study of consecutively admitted patients in a specialized center for acute stroke. Patients with a transient ischemic attack, subarachnoid hemorrhage, cerebral venous thrombosis, hemorrhagic stroke with secondary cause, non-acute stroke, or those who did not consent to participate were excluded. Swallowing was evaluated by speech language pathologists using Volume-Viscosity Swallow Test. General function at three months post-stroke was assessed using the following instruments: Modified Rankin scale, Barthel Index and Functional Independence Measure. Results: A total of 831 patients were admitted and 305 patients were included according to the inclusion and exclusion criteria. The mean age of patients was 63.6±13.3 years, mean time from stroke to swallowing assessment was 4.2±4.1 days, and 45.2% of the patients had dysphagia. Age (OR=1.02; 95%CI 1.00-1.04; p=0.017), known medical history of obstructive sleep apnea (OR=5.13; 95%CI 1.74-15.15; p=0.003), and stroke severity at hospital admission (OR=1.10; 95%CI 1.06-1.15; p<0.001) were independently associated with dysphagia. Dysphagia (OR=3.78; 95%CI 2.16-6.61; p<0.001) and stroke severity (OR=1.05; 95%CI 1.00-1.09; p=0.024) were independently associated with death or functional dependence at three months. Conclusions: Dysphagia was present in almost half of stroke patients. Age, obstructive sleep apnea, and stroke severity were predictors of dysphagia, which was independently associated with death or functional dependence at three months.

ABSTRACT The long-term outcome of acute lymphoblastic leukemia has improved dramatically due to the development of more effective treatment strategies. L-asparaginase (ASNase) is one of the main drugs used and causes death of leukemic cells by systematically depleting the non-essential amino acid asparagine. Three main types of ASNase have been used so far: native ASNase derived from Escherichia coli, an enzyme isolated from Erwinia chrysanthemi and a pegylated form of the native E. coli ASNase, the ASNase PEG. Hypersensitivity reactions are the main complication related to this drug. Although clinical allergies may be important, a major concern is that antibodies produced in response to ASNase may cause rapid inactivation of ASNase, leading to a worse prognosis. This reaction is commonly referred to as "silent hypersensitivity" or "silent inactivation". We are able to analyze hypersensitivity and inactivation processes by the measurement of the ASNase activity. The ability to individualize the ASNase therapy in patients, adjusting the dose or switching patients with silent inactivation to an alternate ASNase preparation may help improve outcomes in those patients. This review article aims to describe the pathophysiology of the inactivation process, how to diagnose it and finally how to manage it.

Abstract Spore forming bacteria can play an important role in food quality and safety as spoilage and pathogenic microorganisms due to resistance to heat-treatment. However, there are limited number of studies focused on evaluate the microbiological quality and the occurrence of these bacteria in UHT goat milk, soymilk and dairy beverage of goat milk and soy protein. In this context, 75 samples of these beverages were evaluated regarding heterotrophic mesophilic microorganisms by conventional plate count and selective methods to detect microorganisms from Bacillus cereus group and Clostridium perfringens. Population counts greater than 104 CFU.ml-1 of heterotrophic mesophilic microorganisms were observed in 80% of the lots of goat milk and 100% of the lots of soymilk and dairy beverage of goat milk and soy protein. The presence of bacteria belonging to B. cereus group was observed in 16%, 52% and 44% of goat milk, soymilk and dairy beverage of goat milk and soy protein, respectively. C. perfringens was isolated from 8% samples of UHT soymilk. The frequency of genes hblA, hblB, hblC, nheA, nheB, nheC in 29 isolates obtained from these products was 62%, 48.2%, 96.5%, 79.3%, 68.9% and 79.3%, respectively. The microbiological quality of the evaluated products was unsatisfactory.

Abstract During corn industrial dry milling, a residue rich in dietary fibers is generated. This study aimed to evaluate the effects of micronized corn fiber (MCF) as part of a cafeteria diet in the macronutrient metabolism and body weight. Wistar male rats, with initial body weight of 249 ± 14 g (n = 13), received AIN-93M diet (Group 1) or cafeteria diet (Groups 2, 3 and 4), composed of commercial ration, cookies, fried potato sticks, milk chocolate, bacon and chicken liver pâté. Groups 3 and 4 received MCF to replace 100 and 50% of the cellulose from the AIN-93M diet, respectively. After 35 days, blood, tissues and feces were collected. Data were analyzed by ANOVA followed by Tukey test (p < 0.10). The weight gain of the animals increased by 25.9%, 20.8% and 22.0%, when fed cafeteria diet or 100 and 50% of MCF respectively, compared to the control group, although food consumption did not differ between them. Body weight and food efficiency ratio did not differ between the groups fed cafeteria diet with or without MCF. The addition of MCF to the cafeteria diet did not alter the animal lipid profile and glycemia, however, the accumulation of lipids in their livers was similar to the control group. The intake of 100% MCF resulted in higher fecal weight and fecal excretion of lipids, and lower fecal nitrogen, lipid absorption and lipid deposition in the liver than the cafeteria diet. In conclusion, MCF has a potential to improve intestinal transit and lipid excretion, but showed no benefit on blood lipid and glucose levels.

RESUMO Objetivo: Avaliar o impacto da terapia sobre a densidade mineral óssea (DMO) e composição corporal em sobreviventes da leucemia linfoide aguda (LLA), tratados de acordo com os protocolos brasileiros do Grupo Cooperativo Brasileiro de Tratamento de Leucemia Linfoide Aguda na Infância (GBTLI), LLA-93 e LLA-99. Métodos: Em estudo transversal com 101 pacientes, avaliaram-se a composição corporal e a DMO por meio da densitometria óssea, interpretando-a conforme a faixa etária e a população de referência. Foi considerado grupo de risco para baixa DMO valores de z-escore entre -1,1 e -1,9 no grupo dos menores de 20 anos. Compararam-se os valores da DMO com características clínicas, tratamento recebido e composição corporal. Foram utilizados os testes qui-quadrado, exato de Fisher, razão de verossimilhança e t de Student, com nível de significância de 5%. Resultados: Foram encontradas 2% de fraturas, 2% de osteonecrose e 2,9% de baixa DMO. No grupo de pacientes com menos de 20 anos, três apresentaram baixa DMO. Os 16 pacientes com risco para baixa DMO exibiram menores valores em vértebras lombares L1-L4 (p=0,01), corpo total (p=0,005) e valores mais baixos de massa magra (p=0,03). No grupo de 22 pacientes com mais de 20 anos, dez demonstraram osteopenia. Conclusões: O baixo impacto do tratamento sobre a DMO neste estudo ratifica o conceito de que o ganho de massa óssea ocorre com o aumento da idade e que o tratamento não influencia tal processo. A população de risco para baixa DMO demonstrou valores menores de massa óssea, podendo beneficiar-se de um acompanhamento em longo prazo para uma possível toxicidade óssea.

ABSTRACT Objective: To evaluate the impact of therapy on bone mineral density (BMD) and body composition in survivors of acute lymphoblastic leukemia (ALL) treated in accordance with Brazilian protocols by the Brazilian Cooperative Group of Treatment of Lymphoblastic Leukemia in Childhood (GBTLI) LLA-93 and LLA-99. Methods: A cross-sectional study with 101 patients was performed. BMD and body composition were evaluated using bone densitometry and were interpreted according to the age group and the reference population. Values between -1.1 and -1.9 in the group of children under 20 years were considered as risk group for low BMD z-scores. BMD values were compared to clinical characteristics, treatment received and body composition. A chi-square test, Fisher’s exact test, likelihood ratio and Student’s t-test were applied, with a 5% significance level. Results: The patients presented a frequency of fractures of 2%, of osteonecrosis, 2%, and of low BMD, 2.9%. In the group of 79 patients under 20 years of age, three had low BMD. The 16 that presented risk for low BMD, demonstrated lower valutes in lumbar vertebrae L1-L4 (p=0.01) and whole body (p=0.005), and smaller values of lean body mass (p=0.03). In the group of 22 patients over 20 years of age, ten had osteopenia. Conclusions: The low impact of treatment on BMD of this study confirms the concept that the bone mass gain occurs with increasing age and that the treatment does not influence the process. The population at risk for low BMD values presented lower bone mass values and could benefit from a long-term monitoring for possible bone toxicity.

AbstractThe Atlantic Forest has species of native fruits, consumed fresh and processed, which have an important contribution to food sovereignty of families that consume it. This study examined the physical and physicochemical characteristics, proximate composition, concentration of carotenoids, vitamin C, vitamin E and minerals in the pulp and kernels of fruits of licuri (Syagrus coronata (Mart.) Becc.). Titratable acidity was analyzed by volumetric neutralization, soluble solids by refractometry, proteins by the micro-Kjeldahl method, lipids by gravimetry using soxhlet, dietary fiber by non-enzymatic gravimetry, carotenoids and vitamin C by HPLC-DAD, vitamin E by HPLC-fluorescence, and minerals by ICP-AES. Pulp were a source of Zn (0.95 mg 100–1), a good source of fiber (6.15 g 100–1), excellent source of provitamin A (758.75 RAE 100–1), Cu (0.69 mg 100–1), Fe (3.81 mg 100–1), Mn (3.40 mg 100–1) and Mo (0.06 mg 100–1). The kernel were a source of Fe (3.36 mg 100–1) and excellent source of Mn (6.14 mg 100–1), Cu (0.97 mg 100–1) and Mo (0.07 mg 100–1). The nutritional value and wide availability of licuri fruit make it an important resource for reducing food insecurity and improving nutrition of the rural population and other individuals who have access to it.

Objective: To describe the implementation of a robot for the preparation of antineoplastic drugs in the Pharmacy Service and to be able to analyze the added value to pharmacotherapy Methods: The implementation was carried out in June 2012 at a tertiary level Hospital, taking place in two periods: 1- test period with the installation of the robot, with technical configuration of the equipment and validation of 29 active ingredients and the integration of electronic prescribing software with the robot application (9 months). 2- Usage period (22 months). On the other hand, training was given to pharmacists and nurses. The robot uses image recognition, barcode identification and gravimetric controls for proper operation. These checks provide information about the error ratio in the preparation, with a margin of ± 10%, which after a pilot study was restricted to a range of ±4%. The robot was programmed to recognize bags, infusion pumps, syringes and vials. The added value was assessed for 31 months by identifying preparation's errors. Results: 11,865 preparations were made by the robot, which meant approximately 40% of all antineoplastic prepared from 29 different active ingredients. 1.12% (n=133) of the errors were identified by the robot and therefore didn't reach the patient (negative desviation - 4%). These errors were corrected manually Conclusion: The implementation of a robot in the preparation of antineoplastic drugs allows to identify errors therefore preventing them to arrive to the patient. This promotes safety and quality of the process, reducing the exposure to cytotoxic drugs from the manipulator.

Resultados: Se realizaron 1 1.865 preparaciones en el robot, que correspondieron al 40% del global de antineoplásicos elaborados, de 29 principios activos diferentes. Se identificaron y evitaron errores de dosificación en el 1,12% (n=133) de las preparaciones, que no alcanzaron al paciente al ser identificadas por el robot como preparaciones con desviación negativa (-4%) y ser corregidas manualmente. Conclusiones: La implantación de un robot en la elaboración de antineoplásicos permite identificar los errores de elaboración y evitar que lleguen al paciente, promoviendo la seguridad y calidad del proceso farmacoterapéutico de antineoplásicos y reduciendo la exposición del manipulador a los mismos.

Objetivou-se caracterizar as propriedades físico-químicas e a correlação entre a textura instrumental e a aceitação sensorial de massas de pizza fortificadas com farinha integral de soja. Foram desenvolvidas formulações contendo 0%, 30%, 50% e 70% de farinha integral de soja. A análise de textura indicou que a adição de 50% de soja elevou (P<0,05) a dureza, gomosidade, elasticidade e mastigabilidade da massa de pizza. Os teores de proteína, fibra alimentar e dos minerais cálcio, zinco, magnésio, potássio, cobre e fósforo foram maiores (P<0,05) com o aumento da concentração da farinha de soja. O conteúdo de lipídio foi maior (P<0,05) na massa de pizza com 70% de farinha integral de soja. A formulação controle e aquela contendo 30% de farinha integral de soja foram as mais aceitas, sendo positivamente correlacionadas com a textura instrumental, uma vez que apresentaram menor dureza, gomosidade, elasticidade e mastigabilidade. Portanto, a farinha de soja adicionou minerais antioxidantes, proteína, fibra dietética, ácidos graxos essenciais (ω-6 e ω-3) e manteve a aceitação das massas de pizza, possibilitando o preparo de um alimento com alegação de saúde e qualidade sensorial

This study aimed to characterize the physicochemical properties and the correlation between the instrumental texture and the sensory acceptance of pizza dough's fortified with whole soybean flour. Formulations were developed to contain 0%, 30%, 50% and 70% whole soybean flour. The texture analysis indicated that the addition of 50% soybean increased (P<0.05) firmness, gumminess, springiness and chewiness of pizza dough. The contents of protein, dietary fiber and and minerals calcium zinc, magnesium, potassium, copper and phosphorus were higher (P<0.05) with increasing concentration of soybean flour. The content of lipid was higher (P<0.05) in the pizza dough with 70% whole soybean flour. The control formulation and that containing 30% whole soybean flour were the most accepted, being positively correlated with the instrumental texture, since it had a lower firmness, gumminess, springiness and chewiness. Thus, the whole soybean flour added antioxidant minerals, protein, dietary fiber, essential fatty acids (ω-6 and ω-3) and maintained the acceptance of the pizza dough's, allowing to prepare food with health claim and sensory quality

The degermination of corn grains by dry milling generates 5% of a fibrous residue. After segregation and micronization, corn bran becomes a potential source of dietary fiber consumption. However, its effect on iron bioavailability has not been reported in the literature. The objective of the present study was to determine the nutritional composition of corn bran and its effects on iron bioavailability using the hemoglobin depletion-repletion method in rats. The animals were divided into two groups: cellulose (control) and corn bran (experimental). The bran had high content of total dietary fiber, especially the insoluble fraction, and low phytate content. Hemoglobin uptake did not differ between groups at the end of repletion period, and the iron relative bioavailability value of the corn bran diet was 104% in comparison to that of the control group. The product evaluated proved to be a potential source of dietary fiber and it showed no negative effects on iron bioavailability.

The aim of this work was to study the effects offortification ofpo-tato bread with whole soybean flour on theirphysicochemical and sensory properties. Control formulations containing 30%, 50% and 70% soybean flour were developed. Firmness, cohesiveness, gumminess and chewiness of bread increased with the addition ofwhole soybean flour. The contents ofprotein, dietary fiber and minerals calcium, zinc, magnesium, copper and phosphorus increased with elevated concentration of soybean flour, while the lipid profile was unchanged. Preference mapping indicated greater acceptance of the control and 30% whole soybean flour formulations. These results were correlated to texture and showed that the greater firmness negatively affected its acceptance. It was concluded that the formulation with 30% was the best option offering good acceptance and high content of nutrients, which makes the flour substitution a viable alternative for the preparation of fortified baking products with equal sensory and physicochemical quality.

O objetivo deste trabalho foi investigar os efeitos da fortificaçao de paes de batata com farinha integral de soja sobre as propriedades físico-químicas e sensoriais. Foram desenvolvidas as formulaçôes controle e contendo 30%, 50% e 70% de farinha de soja. A dureza, coesividade, gomosidade e mastigabilidade dos paes aumentaram com a farinha integral de soja. Os teores de proteína, fibra alimentar e dos minerais cálcio, zinco, magnésio, cobre e fósforo foram maiores em funçao do aumento da concentraçao de farinha integral de soja, enquanto o perfil de lipídios nao foi alterado. O Mapa de Preferência Interno indicou maior aceitaçao das formulaçôes controle e com 30% de farinha integral de soja. Esses resultados foram correlacionados à textura das formulaçôes e revelaram que a maior dureza afetou negativamente sua aceitaçao. Concluise que a formulaçao com 30% foi a melhor opçao em relaçao aos parâmetros físico-químicos e sensoriais, o que torna a substituiçao das farinhas alternativa viável para elaboraçao de produtos de panificaçao fortificados e com qualidade físico-química e sensorial.

Este estudo teve como objectivo analisar o ciclo vigília-sono em enfermeiros que trabalham por turnos, bem como a qualidade do sono e cronótipo. O ciclo vigília-sono foi avaliado através do diário de sono, num total de 60 enfermeiros, com idade média de 31.76 anos. Para o cronótipo utilizou-se o Questionário de Horne e Östberg, de 1976, e para medir a qualidade de sono calculou-se o Índice Qualidade de Sono de Pittsburg (PSQI). Os resultados do cronótipo mostraram uma predominância para tipo indiferente (65.0%), seguido do tipo Moderamente Vespertinos (18.3%), Definitivamente Vespertino (8.3%), Moderadamente Matutinos (6.6%) e Definitivamente Matutinos (1.8%). A percepção da qualidade do sono autorreportada pela Escala Analógica Visual (VAS) foi de 5.85 pontos, em média, para o sono nocturno e 4.70 para o sono diurno, diferença estatisticamente significativa. Os participantes demonstraram que o tempo de acordar e adormecer durante a semana e o fim-de-semana foram estatisticamente diferentes. No PSQI obteve-se uma média de 7.0 pontos, caracterizando o sono como de má qualidade. Os dados permitiram classificar o sono dos enfermeiros como de má qualidade. A falta de hábitos desportivos e o esquema de trabalho em turnos poderão ter influenciado na qualidade de sono.

The scope of this study was to evaluate the sleep/wake cycle in shift work nurses, as well as their sleep quality and chronotype. The sleep/wake cycle was evaluated by keeping a sleep diary for a total of 60 nurses with a mean age of 31.76 years. The Horne & Östberg Questionnaire (1976) for the chronotype and the Pittsburgh Sleep Quality Index (PSQI) for sleep quality were applied. The results revealed a predominance of indifferent chronotypes (65.0%), followed by moderately evening persons (18.3%), decidedly evening persons (8.3%), moderately morning persons (6.6%) and decidedly morning persons (1.8%). The sleep quality perception was analyzed by the visual analogical scale, showing a mean score of 5.85 points for nighttime sleep and 4.70 points for daytime sleep, which represented a statistically significant difference. The sleep/wake schedule was also statistically different when considering weekdays and weekends. The PSQI showed a mean of 7.0 points, characterizing poor sleep quality. The results showed poor sleep quality in shift work nurses, possibly due to the lack of sport and shift work habits.

This study aimed to evaluate the physical-chemical, microbiological and sensory characteristics of four formulations of yacon jams. The following characteristics were analyzed: chemical composition, soluble solids, pH, microbiological presence of total coliforms and salmonella at 45 °C, and presence of fungi and yeasts. The yacon jams exhibited high moisture content (> 62%) as well as high concentrations of carbohydrates (> 28%) and total dietary fiber (2.5%), mainly fructooligosaccharides (> 0.9%). The average energy value was 124.6 kcal/100 g. The average pH was 3.8 and the soluble solids measured 27.6 °Brix. All yacon jams complied with standard microbiological requirements and received high acceptance scores, especially the yacon jam and yacon jam with cinnamon. Yacon jam products may offer an excellent alternative to more common jams due to their lower concentrations of simple sugar, lower calorie value, increased presence of dietary fibers, and desirable sensory characteristics.

INTRODUÇÃO: Pacientes com doença renal crônica (DRC) em diálise têm como principal causa de morte doença cardiovascular (DCV) aterosclerótica, tendo a inflamação e a disfunção endotelial relação direta com a aterosclerose. Além disso, a infecção pelo vírus da hepatite C (HCV), comum nestes pacientes, seria outro fator de piora do estado inflamatório. Níveis aumentados de marcadores de disfunção endotelial são encontrados em pacientes com DRC e hepatite C, e poderiam ser importantes marcadores de aterosclerose nestes indivíduos. OBJETIVO: Comparar atividade endotelial de pacientes em hemodiálise com e sem hepatite C. METODOLOGIA: Selecionamos 28 pacientes em hemodiálise que foram divididos em dois grupos: 1-HCV(+): 18 pacientes (anti-HCV[+] e PCR[+]) e 2-HCV(-): 10 pacientes (anti-HCV[-]). Antes da primeira diálise da semana foi coletada amostra de sangue para dosagem sérica de molécula de adesão intercelular-1 (ICAM-1), fator de crescimento vascular endotelial (VEGF), aspartato alanina aminotransferase (ALT) e tempo de atividade da protrombina (TAP) dos grupos. RESULTADOS: Os níveis de ICAM-1 foram elevados em 60,71%, sendo maiores no grupo HCV(+), porém não estatisticamente significativos (p = 0,2024). Não houve correlação entre os níveis de ICAM-1 e tempo de diálise ou níveis de ALT em nenhum dos grupos. Já os níveis de VEGF foram normais em 92,85%; apenas dois pacientes HCV(+) tinham níveis elevados. Também não houve correlação com tempo de diálise ou níveis de ALT em nenhum grupo. CONCLUSÃO: Pacientes em hemodiálise possuem elevada lesão endotelial, porém a presença de infecção crônica pelo HCV não se mostrou um fator agravante deste quadro. Este resultado pode ter ocorrido por conta do pequeno número de pacientes, sendo necessárias análises com maior número de indivíduos para conclusões mais definitivas.

INTRODUCTION: Chronic renal patients undergoing hemodialysis treatment have cardiovascular atherosclerotic disease as the main cause of death. Inflammation and endothelial dysfunction are directly associated with atherosclerosis. Furthermore, the infection resulting from hepatitis C virus, common among such patients, would be another worsening factor of the inflammatory state. Increased levels of endothelial dysfunction markers are found in chronic renal disease and hepatitis C, which could be important markers of atherosclerosis among these subjects. OBJECTIVE: To compare endothelial activity in patients undergoing hemodialysis with and without hepatitis C. METHODOLOGY: We selected 28 patients undergoing hemodialysis and classified them into two groups: 1-HCV(+): 18 patients (anti-HCV[+] and PCR[+]) and 2-HCV(-): 10 patients (anti-HCV[-]). Before the first weekly dialysis, blood samples from both groups were collected for ICAM-1, VEGF, ALT and TAP serum dosage. RESULTS: ICAM-1 levels were high in 60.71%. The highest levels were found in HCV(+) group, though not statistically significant (p = 0.2024). There was no correlation between ICAM-1 levels and the hemodialysis time or ALT levels in any group. On the other hand, VEGF levels were normal in 92.85%. Only two patients HCV(+) had high levels. There was also no correlation between VEGF levels and the dialysis time or ALT levels. CONCLUSION: Patients undergoing hemodialysis have high endothelial lesion, nevertheless, the presence of HCV chronic infection did not prove to be an aggravating factor. This result may be due to the small number of patients, hence further analyses with a larger sample are required for definitive conclusions.
