Objective: To evaluate the nutritional quality of the meals consumed by 105 elderly tourists in a hotel. Method: To ensure the accuracy of the data, three portions of each option were collected and weighed. The three weights were then averaged to create a standard measure. The number of portions that each tourist took for their meal were recorded and later converted to grams using the standard measure. When evaluating the nutritional composition of the selected foods, calories, macronutrients, saturated fat, cholesterol, sodium and fiber content were all taken into consideration. Results: Most of the tourists were females (70%) from Argentina (88%) between the ages of 60 and 85 (85%). It was noted that the males consumed foods with a higher caloric content (175% of recommended amounts), total fat (235%), and saturated fat, cholesterol (151%), proteins (170%) and sodium (133%). The quantities of carbohydrates (102%) and fiber (98%) were appropriate to meet dietary needs.

Objetivo: evaluar la calidad nutritional de la cena consumida por 105 turistas de la tercera edad hospedados en un hotel. Método: para la estandarización previa del peso medio de los alimentos consumidos fueron pesadas tres porciones de cada una de las opciones ofrecidas. El consumo alimentario fue verificado por la observación directa de las porciones servidas en el plato, convertidas posteriormente en gramos. En la evaluación de la composición nutritional de la comida, se consideraron los datos sobre valor energético, macronutrientes, grasa saturada, colesterol, sodio y fibra. Resultados: la mayoría de los turistas era de Argentina (88%), del sexo femenino (70%), con edades entre 60 y 84 años (85%). Se notó un alto consumo de energía (175%), grasas totales (235%), grasas saturadas (207%), colesterol (151%), proteína (170%) y sodio (133%). Se observó un consumo mayor de grasa saturada entre el sexo masculino. La ingestión fue adecuada para carbohidratos (102%) y fibras (98%).

A própolis é um produto resinoso que as abelhas recolhem de certas partes da planta e que apresenta excelentes propriedades medicinais. Este trabalho descreve a isolamento e identificação de triterpenóides e derivados de ácido anacárdico de própolies Brasileira e sua anti-atividade. Suas estruturas foram elucidadas por RMN ¹H e 13C, incluindo técnicas uni e bidimensionais, e comparação com dados da literatura. Os compostos foram caracterizados como: cardanóis (1a + 1b), cardóis (2a + 2b), ácido anacárdico monoeno (3), α-amirina (4), β-amirina (5), cicloartenol (6), 24-metileno-cicloartenol (7) e lupeol (8). A determinação da posição da ligação dupla após reação com dissulfeto de dimetila (DMDS) é descrita para os derivados fenólicos. O extrato etanólico foi testado in vitro para atividade anti-bacterina pelo método de difusão em disco e mostrou resultados significativos contra Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa e Shigella spp.

Propolis is a sticky, gummy, resinous substance collected by honeybees (Apis mellifera L.) from various plant sources, which has excellent medicinal properties. This paper describes the isolation and identification of triterpenoids and anacardic acid derivatives from Brazilian propolis and their antibacterial activity. Their structures were elucidated by ¹H and 13C NMR, including uni- and bidimensional techniques; in addition, comparisons were made with data from academic literature. These compounds were identified as: cardanols (1a + 1b), cardols (2a + 2b), monoene anacardic acid (3), a-amirine (4), b-amirine (5), cycloartenol (6), 24-methylene-cycloartenol (7) and lupeol (8). The determination of the position of the double bond after a reaction with Dimethyl disulfide (DMDS) is described for the phenol derivatives. The ethanolic extract was tested in vitro for antimicrobial activity by using the disc diffusion method and it showed significant results against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Shigella spp.

OBJETIVOS: A fibrose cística (FC) é a doença genética letal, de herança autossômica recessiva, mais comum entre pacientes de cor branca. O presente estudo foi realizado com o objetivo de identificar o quadro clínico e nutricional à admissão dos pacientes no Centro de Tratamento de FC do HC-UFMG e avaliar a sobrevida a longo prazo. PACIENTES E MÉTODOS: Em um período de 20 anos, 127 pacientes portadores de FC foram acompanhados longitudinalmente e submetidos a protocolo previamente estabelecido, após confirmação do diagnóstico pelo teste do suor. Foram obtidos na admissão dados demográficos, da apresentação clínica, nutricionais e laboratoriais. O genótipo foi obtido de 106 pacientes pela técnica do PCR. Os pacientes foram seguidos por mediana de 44 meses. A análise de sobrevida foi realizada utilizando-se o método de Kaplan-Meier. RESULTADOS: A mediana da idade do diagnóstico da FC foi de 33 meses. A manifestação clínica predominante na época do diagnóstico foi a associação de sintomas respiratórios e gastrointestinais crônicos, presentes em 61% das crianças. A mutação mais freqüente encontrada foi a deltaF508: 17 pacientes (16%) eram homozigotos para essa mutação e 30 (28%) eram heterozigotos. Houve uma prevalência de desnutrição à admissão de 63% tendo sido reduzida para 45% ao final do seguimento. Um total 20 pacientes (15,7%) evoluiu para o óbito. A probabilidade estimada de sobrevida nos primeiros 12 meses após o diagnóstico foi de 96% e após 5 anos de seguimento de 80%. CONCLUSÕES: O diagnóstico da FC é ainda tardio em nosso meio e a sobrevida é menor quando comparada a dados internacionais. O seguimento desses pacientes em centro especializado permitiu uma melhora no estado nutricional apesar da inerente evolução da doença.

BACKGROUND: Cystic fibrosis (CF) is the most common severe autosomal recessive disease in caucasian population. The life expectancy of patients with CF has improved dramatically during the past three decades. A better approach to these patients depends on a better knowledge of clinical course and prognosis of CF. The purpose of the present study was to identify aspects clinical and nutritional on admission at Center of CF (HC-UFMG). MATERIAL AND METHODS: Over a period of 20 years 127 patients with CF were admitted, submitted to a systematic protocol and prospectively followed. Data associated with demographic conditions, clinical presentation, nutritional and laboratory findings on admission were studied. The median follow-up was 44 months. The genotype was performed by PCR method. The survival analysis was carried out by Kaplan-Meier method. RESULTS: The median age at diagnosis was 33 months. Sixty-one per cent of patients at diagnosis had chronic pulmonary and gastrointestinal symptoms. Seventeen patients (16%) were homozygous for DF508 mutation and 30 (28%) were heterozygous. There was a standard prevalence of malnutrition of 63% at diagnosis and of 45% at the end of follow up. Twenty patients (15,7%) died during follow up. The estimated probability of survival after one year from diagnosis was 96% and after five years was 80%. CONCLUSIONS: CF diagnosis has been later in our country and the survival is shorter than in developed countries. Management of cystic fibrosis in pediatric specializing centers results in a better nutritional state in spite of clinical progression of the disease.

We investigated the effects of hippocampal lesions with ibotenic acid (IBO) on the memory of the sound-context-shock association during reexposure to the conditioning context. Twenty-nine adult pigeons were assigned to a non-lesioned control group (CG, N = 7), a sham-lesioned group (SG, N = 7), a hippocampus-lesioned experimental group (EG, N = 7), and to an unpaired nonlesioned group (tone-alone exposure) (NG, N = 8). All pigeons were submitted to a 20-min session in the conditioning chamber with three associations of sound (1000 Hz, 85 dB, 1 s) and shock (10 mA, 1 s). Experimental and sham lesions were performed 24 h later (EG and SG) when EG birds received three bilateral injections (anteroposterior (A), 4.5, 5.25 and 7.0) of IBO (1 µl and 1 µg/µl) and SG received one bilateral injection (A, 5.25) of PBS. The animals were reexposed to the training context 5 days after the lesion. Behavior was videotaped for 20 min and analyzed at 30-s intervals. A significantly higher percent rating of immobility was observed for CG (median, 95.1; range, 79.2 to 100.0) and SG (median, 90.0; range, 69.6 to 95.0) compared to EG (median, 11.62; range, 3.83 to 50.1) and NG (median, 7.33; range, 6.2 to 28.1) (P<0.001) in the training context. These results suggest impairment of contextual fear in birds who received lesions one day after conditioning and a role for the hippocampus in the modulation of emotional aversive memories in pigeons.
