Correlação entre estado nutricional e ingestão alimentar em pacientes de hemodiálise

BACKGROUND: Patients in end-stage renal disease often suffer from poor appetite, various comorbidities, and dietary restrictions. Despite regular hemodialysis, nutritional imbalances are frequently reported. Aiming to correlate nutritional status with food ingestion, a prospective study was done in an outpatient group. METHODS: Stable patients undergoing chronic hemodialysis for at least 3 months (n = 44) were investigated by dietary recall and standard anthropometric, biochemical, and bioimpedance determinations, including subjective and objective global assessment. The mean age of the group was 47.0 ± 16.9 years, and 63.6% were men. Body mass index was 22.2 ± 3.9 kg/m² (mean ± SD), calorie intake was 1471 ± 601 kcal/day (20.7 ± 6.7 kcal/kg/day), and protein ingestion was 74.3 ± 16.6 g protein/day (1.2 g/kg/day). Dietary and clinical findings were correlated with nutritional indices by linear regression analysis. RESULTS: Malnutrition estimated by subjective global assessment was very common (>;90%), despite the fact that body mass index and serum albumin were within an acceptable range in the majority of the population. Objective global assessment yelded roughly comparable numerical findings, with 6.8% being well nourished, 61.4% at nutritional risk or lightly undernourished, 29.6% moderately malnourished, and 2.3% severely malnourished. Total calorie intake was devoid of associations, but protein, carbohydrate, and lipid input positively correlated with triceps skinfold (P=.02). Lipid ingestion was the only marker directly associated with arm circumference, and it correlated with body mass index, as well as with total body fat (bioimpedance analysis) (POBJETIVOS: Pacientes em fase final de enfermidade renal frequentemente sofrem de falta de apetite, várias comorbidades e restrições dietéticas, e a despeito de hemodiálise regular, desequilíbrios nutricionais são frequentemente relatados. Com o propósito de correlacionar estado nutricional com ingestão alimentar, um estudo prospectivo foi realizado com pacientes ambulatoriais. MÉTODOS: Doentes estáveis sibmetidos a hemodiálise crônica por no mínimo 3 meses (n= 44) foram investigados mediante recordatório alimentar e determinações convencionais antropométricas, bioquímicas e de bioimpedância , incluindo-se avaliação global subjetiva e também objetiva. A idade do grupo era de 47.0 ± 16.9 anos com 63.6% de homens. O índice de massa corporal situava-se em 22.2 ± 3.9 kg/m2, a ingestão calórica foi de 1471 ± 601 kcal/dia (20.7 ± 6.7 kcal/kg/dia) e o consumo proteico atingiu 74.3 ± 16.6 g proteina/dia (1.2 g/kg/dia) . As variáveis dietéticas e clínicas foram correlacionadas com os índices nutricionais através da análise de regressão linear. RESULTADOS: A desnutrição estimada pela avalia;áo global subjetiva foi muito comum (>;90%), apesar de que o índice de massa corporal e a taxa de albumina estavam aceitáveis na maioria da população. A avaliação objetiva global evidenciou resultados numericamente parecidos, com 6,8% bem nutridos, 61,4% com risco nutricional ou desnutrição leve, 29,6% no patamar moderado e 2,3% exibindo desnutrição grave. O ganho calórico total não apresentou associações, todavia ingressos de proteina, carboidratos e lípides se correlacionaram positivamente com a prega cutânea do tríceps (P=0.02). Apenas a ingestão lipídica associou-se diretamente com a circunferência do braço, demonstrando ainda correlação com o índice de massa corporal bem como com a gordura corpórea total (bioimpedância) (

Soroprevalência de brucelose em suínos de granjas comerciais e em criatórios de subsistência.

Resumo: A suinocultura industrial compreende o conjunto de produtores que incorporam os avanços tecnológicos em genética, nutrição, sanidade e demais aspectos produtivos, enquanto a suinocultura de subsistência desempenha um papel importante para a alimentação humana, sendo a criação de suínos em criatórios amplamente difundida entre os pequenos proprietários de terra ou em assentamentos. Este trabalho teve como objetivo avaliar a pesquisa de anticorpos contra Brucella sp. nos suínos de granjas comerciais, criatórios de subsistência e javalis asselvajados. Foram visitados 32 criatórios de suínos domésticos localizados na região sul de Mato Grosso do Sul. Considerando-se os fenótipos, verificou-se que os sinais indicativos de contato têm influência do município onde está situada a propriedade (?2=8.8594, p=0,0029), sendo que o município de Deodápolis tem uma chance de ocorrência mais elevada (OR=13,00;IC95%:2,12-79,59). Através da detecção fenotípica observa-se a presença de animais híbridos nas propriedades analisadas, e evidencia-se assim que os animais da propriedade em algum momento entraram em contato com suínos asselvajados, os quais podem ser responsáveis pela disseminação de diversas patologias. A ausência da detecção de anticorpos anti-Brucella sp. em suínos de criatórios sugere que a bactéria não é circulante nas populações de javalis nas áreas de estudo. Abstract: Industrial pig farming comprises the group of producers that incorporate technological advances in genetics, nutrition, health and other productive aspects, while subsistence pig farming plays an important role for human nutrition, with the creation of pigs in farms being widely spread among small farms. landowners or settlements. This study aimed to evaluate the search for antibodies against Brucella sp. pigs on commercial farms, livestock farms and wild boars. Were visited 32 domestic swine farms located in the southern region of Mato Grosso do Sul. Considering the phenotypes, it was found that the indicative signs of contact have influence from the municipality where the property is located (χ2=8.8594, p=0.0029) , and the municipality of Deodápolis has a higher chance of occurrence (OR=13,00;IC95%:2,12-79,59). Through the phenotypic detection, the presence of hybrid animals in the analyzed properties is clearly observed, and it is evident that the animals of the property at some point came into contact with pigs, which may be responsible for the spread of several pathogens. The absence of detection of anti-Brucella sp. in breeding pigs it suggests that the bacteria is not circulating in wild boar populations in the study areas

Correlation of nutritional status and food intake in hemodialysis patients

BACKGROUND: Patients in end-stage renal disease often suffer from poor appetite, various comorbidities, and dietary restrictions. Despite regular hemodialysis, nutritional imbalances are frequently reported. Aiming to correlate nutritional status with food ingestion, a prospective study was done in an outpatient group. METHODS: Stable patients undergoing chronic hemodialysis for at least 3 months (n = 44) were investigated by dietary recall and standard anthropometric, biochemical, and bioimpedance determinations, including subjective and objective global assessment. The mean age of the group was 47.0 &plusmn; 16.9 years, and 63.6% were men. Body mass index was 22.2 &plusmn; 3.9 kg/m² (mean &plusmn; SD), calorie intake was 1471 &plusmn; 601 kcal/day (20.7 &plusmn; 6.7 kcal/kg/day), and protein ingestion was 74.3 &plusmn; 16.6 g protein/day (1.2 g/kg/day). Dietary and clinical findings were correlated with nutritional indices by linear regression analysis. RESULTS: Malnutrition estimated by subjective global assessment was very common (>90%), despite the fact that body mass index and serum albumin were within an acceptable range in the majority of the population. Objective global assessment yelded roughly comparable numerical findings, with 6.8% being well nourished, 61.4% at nutritional risk or lightly undernourished, 29.6% moderately malnourished, and 2.3% severely malnourished. Total calorie intake was devoid of associations, but protein, carbohydrate, and lipid input positively correlated with triceps skinfold (P=.02). Lipid ingestion was the only marker directly associated with arm circumference, and it correlated with body mass index, as well as with total body fat (bioimpedance analysis) (P <.001). CONCLUSIONS: 1) Bioimpedance analysis was useful and was correlated with clinical findings; 2) Lipid intake was the best dietary index in this experience, surpassing protein or total energy; 3) Despite its shortcomings, dietary recall was useful in the assessment of hemodialysis patients
