Estado nutricional e consumo alimentar de vegetarianos estritos e não estritos / Nutritional status and food consumption of strict and non-strict vegetarians

Introdução: O número de adeptos ao vegetarianismo tem crescido consideravelmente. Observa-se que, entre as vantagens de se adotar uma dieta vegetariana, está o menor risco de desenvolver sobrepeso e obesidade, o que pode estar relacionado com o alto consumo de vegetais e práticas importantes de estilo de vida. Objetivos: Avaliar o estado nutricional e a frequência do consumo alimentar de vegetarianos não estritos e estritos. Métodos: Estudo transversal descritivo, realizado com participantes do grupo "Vegans SLZ", de ambos os sexos e com idade a partir de 18 anos. A coleta de dados ocorreu de janeiro a março de 2020. Foi realizada aplicação de questionários sobre dados de frequência do consumo alimentar, socioeconômico e de estilo de vida e a aferição de medidas de peso corporal, estatura e de percentuais de gordura corporal e massa muscular. Os dados foram tabulados no Excel 2010® e analisados no programa estatístico R Studio versão 3.6.1. Resultados: Dos 43 vegetarianos avaliados, a maioria seguia a dieta vegetariana estrita (55,81%) e era eutrófica (62,79%), 32,56% apresentaram alto percentual de gordura corporal e 53,49% percentual de massa magra corporal normal. Foi frequente o consumo de pães, cereais, tubérculos, leguminosas, oleaginosas, frutas e verduras, e 41% consumiam alimentos industrializados de 4 a 7 vezes por semana. Conclusões: A maioria da amostra tinha estado nutricional eutrófico e consumo regular de todos os grupos alimentares, porém com importante consumo de alimentos industrializados.

Introduction: The number of adherents to vegetarianism has grown considerably. It is observed that, among the advantages of adopting a vegetarian diet, there is a lower risk of developing overweight and obesity, which may be related to the high consumption of vegetables and important lifestyle practices. Objectives: To assess the nutritional status and frequency of food consumption of non-strict and strict vegetarians. Methods: Descriptive cross-sectional study carried out with participants of the "Vegans SLZ" group, of both sexes and aged 18 years and over. Data collection took place from January to March 2020. Questionnaires were applied to data on frequency of food, socioeconomic and lifestyle consumption and measurements of body weight, height and percentages of body fat and muscle mass were measured.

Abstract Background Considering the magnitude of systemic hypertension (SH) and its complications, as well as the importance of regular physical activity in its prevention and/or treatment, there is a necessity to identify the factors associated with insufficient practice of physical activity. Objective To analyze factors associated with insufficient physical activity in hypertensive patients treated at Primary Health Care (PHC). Method This cross-sectional study was performed with a random sample of 305 hypertensive patients in three PHC units in São Luis, state of Maranhão, Brazil. A bivariate analysis was performed with estimates of prevalence ratios and confidence intervals, and multivariate analysis using Poisson regression. Results Insufficient physical activity was observed in 38.7% of the sample. Insufficient physical activity was associated with having <8 years of formal education (prevalence ratio-PR=1.58; 95% confidence interval-CI=1.04-2.39), total cholesterol ≥200 mg/dL (PR=0.78; 95% CI=0.58-1.04), low-density lipoprotein cholesterol-LDL ≥100 mg/dL (PR=0.79; 95% CI=0.53-0.95), and high-density lipoprotein cholesterol-HDL <40 mg/dL among men and <50 mg/dL among women (PR=1.21; 95% CI=0.90-1.64). Length of education <8 years (PR=1.50; 95% CI=0.99-2.29) and LDL ≥100 mg/dL (PR=0.72;95% CI=0.54-0.96) were also associated in the multivariate regression. Conclusion High prevalence of insufficient physical activity and its association with low education level and altered LDL serum levels were observed in hypertensive patients.

Fatores associados ao elevado percentual de gordura corporal em indivíduos fisicamente ativos / Factors associated with the high body fat percentage in physically active individuals

Introdução: O exercício físico é praticado com diversos objetivos, destacando-se a promoção na mudança da composição corporal, com a redução de gordura e aumento de massa magra. Assim, compreender os fatores que podem estar associados nesta modificação se torna relevante. Objetivo: Analisar os fatores demográficos, estilo de vida, bioquímico, alimentares e de treinamento associados ao percentual de gordura corporal em praticantes de exercício físico em academias. Materiais e Métodos: Estudo transversal com 143 praticantes de exercícios físicos saudáveis, de ambos os sexos. Características sociodemográficas e estilo de vida foram obtidas através da aplicação de questionário. O consumo alimentar foi obtido através de registros alimentares de 24h, considerando as médias de três dias. A composição corporal foi avaliada por meio de avaliação antropométrica e pelo teste de bioimpedância elétrica. A análise estatística contemplou o teste de Shapiro Wilk para verificação da normalidade; o qui-quadrado e exato de Fisher foram usados para avaliar a associação entre as variáveis categóricas e a variável resposta e os testes de Mann-Whitney e t de Student para as contínuas. A regressão de Poisson com variância robusta foi usada para determinar as associações entre variáveis estudadas. O software Stata versão 14.0 foi usado para análise estatística, tendo sido adotado o valor de p <0,05. Resultados: A prevalência de gordura corporal elevada foi de 49,3% nos homens e 79,2% nas mulheres. Os fatores associados foram o maior consumo de proteína e fibras nas mulheres e a concentração de monócitos nos homens. Conclusão: Apesar de se tratar de público fisicamente ativo, observou-se elevado percentual de gordura entre os participantes do estudo e os fatores associados reforçam o caráter multietiológico deste indicador.

Introduction: Physical exercise is practiced with several objectives, especially the promotion of changes in body composition, with fat reduction and increase in lean mass. Thus, understanding the factors that may be associated with this modification becomes relevant. Objective: To analyze demographic, lifestyle, biochemical, dietary, and training factors associated with the percentage of body fat in practitioners of physical exercise in gyms. Materials and Methods: Cross-sectional study with 143 healthy physical exercise practitioners, of both sexes. Sociodemographic characteristics and lifestyle were obtained through the application of a questionnaire. Food consumption was obtained through 24-hour food records, considering the averages of three days. Body composition was assessed using anthropometric assessment and the electrical bioimpedance test. The statistical analysis included the Shapiro Wilk test to verify normality, the chi-square and Fisher's exact test were used to assess the association between categorical variables and the response variable and the Mann-Whitney and Student t tests for the continuous variables. Poisson regression with robust variance was used to determine the associations between studied variables. Stata software version 14.0 was used for statistical analysis and a value of p <0.05 was adopted. Results: The prevalence of high body fat was 49.3% in men and 79.2% in women. The associated factors were the higher consumption of protein and fibers in women and the concentration of monocytes in men. Conclusion: Despite being a physically active public, a high percentage of fat was observed among the study participants and the associated factors reinforce the multi-etiological character of this indicator.

Ganglion cells and displaced amacrine cells density in the retina of the collared peccary (Pecari tajacu).

In the present study, we investigated the topographical distribution of ganglion cells and displaced amacrine cells in the retina of the collared peccary (Pecari tajacu), a diurnal neotropical mammal of the suborder Suina (Order Artiodactyla) widely distributed across central and mainly South America. Retinas were prepared and processed following the Nissl staining method. The number and distribution of retinal ganglion cells and displaced amacrine cells were determined in six flat-mounted retinas from three animals. The average density of ganglion cells was 351.822 ± 31.434 GC/mm2. The peccary shows a well-developed visual streak. The average peak density was 6,767 GC/mm2 and located within the visual range and displaced temporally as an area temporalis. Displaced amacrine cells have an average density of 300 DAC/mm2, but the density was not homogeneous along the retina, closer to the center of the retina the number of cells decreases and when approaching the periphery the density increases, in addition, amacrine cells do not form retinal specialization like ganglion cells. Outside the area temporalis, amacrine cells reach up to 80% in the ganglion cell layer. However, in the region of the area temporalis, the proportion of amacrine cells drops to 32%. Thus, three retinal specializations were found in peccary's retina by ganglion cells: visual streak, area temporalis and dorsotemporal extension. The topography of the ganglion cells layer in the retina of the peccary resembles other species of Order Artiodactyla already described and is directly related to its evolutionary history and ecology of the species.

Perfil Clínico e Bioquímico de Pacientes em Hemodiálise com Hiperparatireoidismo Secundário / Clinical and Biochemical Profile of Patients on Hemodialysis with Secondary Hyperparathyroidism

Objetivo: Avaliar o perfil clínico e bioquímico de pacientes com e sem HPTS. Metodologia:Estudo transversal e analítico realizado com 93 pacientes com DRC em HD. Os pacientes foram alocados em dois grupos: sem HPTS (Paratormônio: < 300pg/mL) e com HPTS (Paratormônio: ≥ 300pg/mL). Foram verificados os dados socioeconômicos por meio de questioná-rio semiestruturado. Os dados bioquímicos e antropométricos foram obtidos por meio do prontuário de cada paciente. Tam-bém foram coletadas informações quanto ao tempo de HD, tabagismo, diabetes mellitus, hipertensão arterial sistêmica, cardiopatias, atividade física e a razão triglicerídeo/HDL-Coles-terol. Resultados:O gênero feminino apresentou-se prevalente no grupo com HPTS (59,09%, p=0,017). Nos pacientes que não apresentavam HPTS foi detectado maior presença de diabetes mellitus (77,27%, p=0,021). Os pacientes com HPTS diferiram dos pacientes sem HPTS para o hematócrito (p=0,0457), crea-tinina (p=0,0303) e a fosfatase alcalina (p=0,0011). Conclusão:Encontramos diferença ao comparar os grupos quanto aos níveis de hematócrito, creatinina, fósforo e fosfatase alcalina, resultados que podem implicar no estado clínico de indivíduos com HPTS. Essas análises poderão direcionar condutas e estratégias específicas para o acompanhamento da doença e proposta adequada de tratamento, buscando a melhora do quadro clínico e qualidade de vida. (AU)

Objective: To evaluate the clinical and biochemical profile of patients with and without secondary hyperparathyroidism. Methodology: Cross-sectional and analytical study conducted with 93 patients with CKD in HD. The patients were allocated into two groups: without HPTS (Parathyroid hormone: <300pg / mL) and with HPTS (Parathyroid hormone: ≥ 300pg / mL). Socioeconomic data were verified through a semi-structured questionnaire. Biochemical and anthropometric data were obtained from each patient's medical record. Information was also collected regarding HD time, smoking, diabetes mellitus, systemic arterial hypertension, heart disease, physical activity and the triglyceride / HDL-cholesterol ratio. Results: The female gender was prevalent in the group with HPTS (59.09%, p = 0.017). In patients without HPTS, a higher presence of diabetes mellitus was detected (77.27%, p = 0.021). Patients with HPTS differed from patients without HPTS for hematocrit (p = 0.0457), creatinine (p = 0.0303) and alkaline phosphatase (p = 0.0011). Conclusion: We found a difference when comparing the groups regarding hematocrit, creatinine, phosphorus and alkaline phosphatase levels. Results that may imply the clinical status of individuals with HPTS. These analysis may direct specific conducts and strategies for the follow-up of the disease and appropriate treatment proposal, seeking to improve the clinical condition and quality of life. (AU)

Psychophysical Evaluation of Visual Functions of Ex-Alcoholic Subjects After Prolonged Abstinence.

Chronic alcohol abuse can lead to a brain damages, and the health status of alcoholics even after a long-term alcohol abstinence is a public health concern. The present study investigated the color vision and spatial luminance contrast sensitivity of a group of 17 ex-alcoholics (46.3 ± 6.7 years old) in long-term alcohol abstinence after having been previously under alcohol dependence for many years. We also investigated the association of impaired psychophysical performance in different tests we applied. The mean time of alcohol consumption was 16.9 ± 5.1 years and the mean abstinence period was 12.4 ± 8.5 years. Achromatic vision of all subjects was evaluated using spatial luminance contrast sensitivity function (CSF) test and color vision was evaluated using Mollon-Reffin color discrimination test (MR) and the Farnsworth-Munsell 100 hue arrangement test (FM100). Relative to controls, the spatial luminance contrast sensitivity was lower in 10/17 of the ex-alcoholic subjects. In the color vision tests, 11/16 ex-alcoholic subjects had impaired results compared to controls in the FM100 test and 13/14 subjects had color vision deficits measured in the MR test. Fourteen subjects performed all visual tests, three subjects had impaired results for all tests, seven subjects had impaired results in two tests, three subjects had visual deficit in one test, and one had normal results for all tests. The results showed the existence of functional deficits in achromatic and chromatic vision of subjects with history of chronic alcoholism after long abstinence. Most subjects had altered result in more than one test, especially in the color vision tests. The present investigation suggests that the damage in visual functions produced by abusive alcohol consumption is not reversed after long term alcohol abstinence.

Visual evoked cortical potential elicited by pseudoisochromatic stimulus.

PURPOSE: Visual evoked cortical potentials (VECPs) are useful for investigating the mechanisms and dysfunctions of color vision. Chromatic sinusoidal gratings are generally used to elicit VECPs, but they require long psychophysical measurements to match the perceptual luminance between their stripes. An alternative method is to use pseudoisochromatic stimuli, which makes use of luminance noise to mask luminance clues and force the target perception to be dependent on chromatic contrast. In this study, we compared VECPs generated by sinusoidal gratings and pseudoisochromatic gratings. Contrary to chromatic sinusoidal gratings, pseudoisochromatic stimuli do not require the use of previous methods to find the equiluminance of the stimulus. METHODS: Normal trichromats were recruited to be tested with red-green chromatic sinusoidal gratings and pseudoisochromatic gratings presented by pattern onset-offset and pattern reversal modes in five spatial frequencies. In addition, we also tested four different chromatic contrast pairs in pattern onset-offset mode presentation in five trichromats and one colorblind subject (deuteranope). RESULTS: Pattern onset-offset VECPs elicited by sinusoidal gratings had a larger amplitude than those obtained with pseudoisochromatic stimuli, whereas pattern reversal VECPs elicited by pseudoisochromatic gratings had similar amplitudes compared to those elicited by sinusoidal gratings. We found no difference between the VECP amplitudes elicited by sinusoidal and pseudoisochromatic gratings containing different chromatic contrast. Color-blind subjects displayed absent or small responses to the stimuli. CONCLUSION: Pseudoisochromatic stimulus can be an alternative stimulus to generate VECPs dominated by the chromatic mechanism.

Fish consumption frequency and lipid peroxidation in the riverside population of Lower Tocantins, Pará / Frecuencia de consumo de pescado y peroxidación lipídica en la población ribereña del Bajo Tocantins, Pará

Introduction: Several studies report the benefits of fish consumption to the prevention of cardiovascular diseases such as atherosclerosis, thrombosis and arrhythmia. On the other hand, regular consumption of fish can induce the accumulation of methylmercury in the body. Objective: To evaluate the relationship between frequency of fish consumption, mercury concentrations and intensity of lipid peroxidation. Methods: A cross - sectional, observational study. It was evaluated riverside in Limoeiro do Ajuru, Pará. Variables were sociodemographic variables, frequency of weekly fish consumption, concentration of total mercury in hair and the dose of malondialdehyde in plasma. The concentrations of total mercury (μg/g) and malondialdehyde (nmol / ml) were respectively 0.63 μg/g and 0.54 nmol/ml for weekly fish consumption less than two meals, 0.51 μg/g 0.42 nmol/ml for consumption in two to four meals and 0.88 μg/g and 0.31 nmol/ml for consumption major than four fish meals. There was a significant difference between groups of two to four and major than four meals, only for the total mercury variable (p = 0.008). Discussion: In this study, low levels exposure and high fish consumption can influencing the bioaccumulation of mercury in this population. Santos et al, found the total mercury concentration (0.09 to 3.79 μg/g) in the rivers and compared the levels according to the intake categories of fish, did not obtain significant statistical difference. This divergent result suggests that deforestation in the Amazon has been increased and is an important vehicle for mercury exposure which affects local survival and subsistence. Conclusion: Riparians in the studied region have high fish consumption and low concentrations of mercury. Although the group with low fish consumption had higher levels of MDA there was no significant difference when compared with other groups

OBJETIVOS: Identificar o risco cardiovascular pela razão triglicerídeo/colesterol ligado à lipoproteína de alta densidade (TG/HDL-c) e verificar a sua associação com fatores sociodemográficos, parâmetros clínicos e índice de massa corporal em pacientes com doença renal crônica em hemodiálise. MÉTODOS: Estudo do tipo transversal, no qual foram avaliados pacientes com doença renal crônica em hemodiálise. A amostragem foi do tipo não probabilística de conveniência. A coleta de dados sociodemográficos foi realizada por meio de entrevista com questionário semiestruturado, e os dados clínicos e laboratoriais foram obtidos em consulta aos prontuários. Para identificação do risco cardiovascular, a razão TG/HDL-c foi calculada a partir dos valores plasmáticos de triglicerídeos (mg/dL) e colesterol ligado à lipoproteína de alta densidade (mg/dL). O ponto de corte para TG/HDL-c considerado como indicativo de risco cardiovascular foi de ≥3,8 mg/dL. Para análise estatística foi utilizado o teste qui-quadrado, e o nível de significância considerado foi de 5% (p<0,05). RESULTADOS: Foram avaliados 71 pacientes, cuja média de idade foi 49,9±13,2 anos, sendo 28 mulheres (50,1±13,2 anos) e 43 homens (49,7±13,2 anos). Entre os 71 pacientes, 31 (43,66%) apresentavam risco cardiovascular caracterizado pela relação TG/HDL-c ≥3,8 mg/dL. Em geral observou-se semelhança quanto ao perfil dos pacientes com e sem risco cardiovascular. Entretanto, nos pacientes que possuíam risco cardiovascular a maior proporção foi do sexo masculino (77,42%), enquanto nos que não possuíam esse risco, o sexo feminino foi mais frequente (52,50%). Esta variável apresentou diferença significativa entre os grupos com e sem risco cardiovascular (p=0,011). CONCLUSÕES: Nesta amostra de pacientes com doença renal crônica em hemodiálise, a razão TG/HDL-c identificou alto índice de risco cardiovascular, sendo que esse risco foi significativamente associado ao sexo masculino.

METHODS: Cross-sectional study, in which patients with chronic kidney disease in hemodialysis were evaluated. A non-probability convenience sampling was used. Sociodemographic data were collected through a semi-structured questionnaire interview, and clinical and laboratory data were obtained from the medical records. For the identification of cardiovascular risk, the TG/HDL-c ratio was calculated from plasma triglycerides (mg/dL) and high density lipoprotein cholesterol (mg/dL). The cut-off point for TG/HDL-c considered to be indicative of cardiovascular risk was ≥3.8 mg/dL. For statistical analysis, the chi-square test was used, and the significance level was set at 5% (p <0.05). RESULTS: A total of 71 patients were evaluated, with a mean age of 49.9±13.2 years, being 28 women (50.1±13.2 years) and 43 men (49.7±13.2 years). Among the 71 patients, 31 (43.66%) had cardiovascular risk characterized by the TG/HDL-c ratio ≥3.8 mg/dL. In general, the profile of patients with and without cardiovascular risk was similar. However, in patients with cardiovascular risk there was a higher proportion of males (77.42%), while in those who did not have this risk, the female gender was morefrequent (52.50%). This variable showed a significant. difference between the groups with and without cardiovascular risk (p=0.011). CONCLUSIONS: In this sample of patients with chronic kidney disease on hemodialysis, the TG/HDL-c ratio identified a high cardiovascular risk index, which was significantly associated with males.

Ácidos graxos essenciais ômega-3 e ômega-6 no leite materno e sua associação com o desenvolvimento infantil: revisão de literatura / Omega-3, omega-6 essential fatty acids and its association with child development: a literature review

O objetivo deste trabalho foi estudar os benefícios que os ácidos graxos essenciais ômega-3 e ômega-6, presentes no leite materno, podem trazer para o desenvolvimento infantil. Trata-se de uma revisão sistemática nas bases de dados PUBMED e BIREME entre 2009 a 2013, utilizando os termos: "Ácidos Graxos Ômega-3", "Ácidos Graxos Ômega-6" e "breast feeding". Foram selecionados 29 artigos, onde apenas 8 permaneceram após leitura dos mesmos na integra, excluindo artigos de revisão, de nota técnica, sem associação entre mãe-filho, assuntos não relacionados com o desenvolvimento infantil e com metodologia baseada em entrevista ou aplicação de questionário. Os principais resultados encontrados pelos autores foram à ingestão destes ácidos durante a gestação como influência no desenvolvimento neurológico, visual e físico do lactente; a ocorrência de variações dos ácidos graxos essenciais, no leite humano, obtidos em diferentes idades gestacionais e estágios de lactação; a elevação nos níveis de ômega-3 e ômega-6, respectivamente, em crianças amamentadas exclusivamente e em crianças alimentadas com fórmulas suplementadas. A associação da ingesta adequada dos ácidos graxos essenciais, ômega-3 e 6, durante os períodos de gestação e lactação com o desenvolvimento infantil a longo prazo foi observada na maioria dos estudos.(AU)

This work aims to study the benefits that omega-3 and omega-6 essential fatty acids, present in breast milk, can bring to a child's development. This is a systematic review that national and international publications were assess in PUBMED and BIREME data from 2009 to 2013 using the terms: "Fatty Acids Omega3", "Fatty Acids Omega-6" and "breast feeding". A total of 29 articles were selected, where only 8 remained the after been read in full, excluding review articles, technical notes, the ones with no association between parent­child, with issues not related to child development and the ones based on an interview or a questionnaire methodology. The main results found by the authors were the intake of these acids during pregnancy as an influence on neurological, visual and physical development of infants; variations occurrence of essential fatty acids in human milk obtained at different gestational ages and stages of lactation, the increased levels of omega-3 and omega-6, respectively, in infants exclusively breastfed and formula-fed. The association of adequate intake of essential fatty acids omega-3 and 6 during the periods of pregnancy and lactation with the child long-term development was observed in most studies.(AU)
