Estocagem tecidual e utilização de lipídeos em Matrinxã, Brycon cephalus (Günther, 1869)

Lipids have important biological functions, suchas membrane constituents, hormone precursors, and are efficient energy reserves, due to thers high caloric content. In fish, but not in mammals, lipid storage patterns are quite diverse. The aim of this study was to determine lipid distribution in somatic and reproductive tissues of matrinxã, Brycon cephalus, both male and female, highlighting somatic indices related to lipid dynamics. From Oct 98 to Jan 99, a total of 174 fish (8-12 each month) were sampled. After fish anesthesia, heparinized blood was collected for plasma triacylglycerol determination. Fish were individually weighed and measured, and liver, gonads and visceral fat were collected and weighed for HSI (hepatosomatic index), GSI (gonad somatic index) and MFI (mesenteric fat index) calculation. The highest values of total lipids were found in red muscle (about 18%), liver and gonads (about 16.5%). The white muscle had a lower concentration (2.5%). Analyses of variance of HSI and MFI showed fluctuations along the experimental period with lowest concentrations in the periods of highest temperatures. Matrinxã store lipids in several body tissues, including mesenteric fat, liver, muscles and gonads.

Indeterminate form of chagas disease and metabolic syndrome: a dangerous combination

Chagas’ disease (CD) has been a major concern in public health in Latin America countries and in Brazil there are about 3 million people suffering from this disease. With the social and economic changes which have been occurring in the last 6 decades in the country, there have been a lot of changes in the population life style with severe metabolic consequences, especially for those with Chagas' disease. The objective of this study was to evaluate the prevalence of metabolic syndrome in individuals with the indeterminate form of CD. A total of 74 individuals, mean age of 55.6 years, participated in the study. Anthropometric and biochemical evaluations were performed. Overweight/obesity was found in 86.5 % of individuals, increased waist circumference in 72.5%, and 67% had more than 30% of fat mass. Hyperglycemia and dyslipidemia were observed in 24.3% and 75.7% of patients, respectively. Metabolic syndrome was diagnosed in 48.2% of patients. The family history revealed high prevalence of cardiovascular diseases (80.3%), systemic arterial hypertension (57.1%) and diabetes mellitus (42.8%). A total of 90% of patients were overweight/obese, and it is well known that increased adipose tissue, specially visceral adipose tissue is highly associated with dyslipidemia and cardiovascular diseases, as well as imbalance in production of proinflammatory and antiinflammatory cytokines produced by that tissue. Adipocytes are also known as a reservoir for Trypanosoma cruzi, favoring an increase in parasite load and a possible reacutization of the disease. Therefore, the study individuals are at high risk of developing cardiovascular diseases as well as further symptomatic form of the Chagas' disease, mainlychagastic cardiopathy.

Prevalence of metabolic syndrome in elderly Japanese-Brazilians

Background: Prevalence of individuals with a high cardiovascular risk is elevated in elderly populations. Although metabolic syndrome (MS) increases cardiovascular risk, information is scarce on the prevalence of MS in the elderly. In this study we assessed MS prevalence in a population of elderly Japanese-Brazilians using different MS definitions according to waist circumference cutoff values. Material/Methods: We studied 339 elderly subjects, 44.8% males, aged between 60 to 88 years (70.1 +/- 6.8). MS was defined according to criteria proposed by the Joint Interim Statement in 2009. As waist circumference cutoff point values remain controversial for Asian and Japanese populations, we employed 3 different cutoffs that are commonly used in Japanese epidemiological studies: 1) >90 cm for men and >80 cm for women; 2) >85 cm for men and >90 cm for women; 3) >85 cm for men and >80 cm for women. Results: MS prevalence ranged from 59.9% to 65.8% according to the different definitions. We observed 90% concordance and no statistical difference (p>0.05) in MS prevalence between the 3 definitions. MS diagnosis according to all 3 cutoff values was found in 55.8% of our population, while in only 34.2% was MS discarded by all cutoffs. The prevalence of altered MS components was as follows: arterial blood pressure 82%, fasting glycemia 65.8%, triglyceride 43.4%, and HDL-C levels 36.9%. Conclusions: Elderly Japanese-Brazilians present high metabolic syndrome prevalence independent of waist circumference cutoff values. Concordance between the 3 definitions is high, suggesting that all 3 cutoff values yield similar metabolic syndrome prevalence values in this population.
