Lipidograma e sensibilidade à insulina em éguas Mangalarga Marchador / Lipidogram and insulin sensitivity in Mangalarga Marchador mares

A dislipidemia é um achado comum, porém não determinante, na síndrome metabólica equina (SME). O objetivo do presente trabalho foi caracterizar a dislipidemia em animais obesos com risco de SME. Para isso, 18 éguas foram alocadas em grupos, de acordo com escore corporal (EC) de 1 a 9: no grupo ideal, animais com EC de 4,5 a 5,5 (n= 6), no grupo sobrepeso, com EC de 6 a 7 (n= 6) e no grupo obeso, animais com EC de 7,5 a 9 (n= 6). Coletaram-se amostras de sangue em jejum de concentrado para determinação de triglicerídeos, colesterol total, glicemia e concentração de insulina. Valores preditivos de sensibilidade à insulina (RISQI) e de secreção ß-pancreática (MIRG) foram calculados. O grupo obeso apresentou níveis maiores em relação aos outros grupos de triglicerídeos (P=0,001) e acima do ideal em concentrações de colesterol (P=0,012). Não foi observada diferença nas concentrações plasmáticas de glicose (P=0,53), de insulina (P=0,10) ou de RISQI (P=0,46). Houve diferença entre os grupos nos valores de MIRG (P=0,048), tendo o grupo obeso obtido resultados maiores quando comparado com o grupo ideal. O aumento do EC foi associado ao aumento das concentrações plasmáticas de colesterol e triglicerídeos, o que caracteriza um estado de dislipidemia e de elevação da secreção das células ß-pancreáticas.(AU)

Increased indicators of fat metabolites are found in Equine Metabolic Syndrome (EMS) subjects, although these parameters are not included in the EMS definition described in the literature and in its diagnosis. The objective of this study was to characterize dyslipidemia in obese insulin resistant mares. 18 mares were allocated in three groups according to body condition score (BCS) in a 1 to 9 scale. In the Ideal group there were animals with BCS 4.5 to 5.5 (n= 6), in the Overweight group, the BCS were 6 to 7 (n= 6), and in the Obese group (n= 6), BCS 7.5 to 9. Concentrate fasting blood samples were taken to determine triglycerides, total cholesterol, glucose, and insulin concentrations in plasma. Insulin sensitivity proxy (RISQI) and ß-pancreatic secretion proxy (MIRG) were calculated from glucose and insulin data. The Obese group had higher triglyceride levels (P= 0.001), compared to other groups, and higher total cholesterol compared to the Ideal Group (P= 0.012). No differences in plasma glucose (P= 0.53), insulin (P= 0.10) concentrations and insulin sensitivity (RISQI: P= 0.463) were seen among groups. The Obese Group had a higher ß-pancreatic secretion (MIRG: P= 0.048) compared to the Ideal Group. The increased BCS was related to the plasma fat metabolites a higher ß-pancreatic secretion.(AU)

Distribution of Elevated Serum Cholesterol and Triglyceride Levels in the General Adult Population of Ngaoundere, Cameroon

Background: Dyslipidemia is a major cardiovascular disease (CVD) risk factor with an increasing occurrence in sub-Saharan Africa. Aim: To determine the distribution of elevated serum cholesterol and triglyceride levels, and assess the level of awareness of dyslipidemias in the general adult population of Ngaoundere, Cameroon. Methodology: This was a community-based cross-sectional study conducted from February to December 2015 in Ngaoundere town. Following a three-stage sampling method, a total 932 participants of at least 20 years old were enrolled. Demographic data were collected, and body mass index (BMI), waist circumference, blood pressure, fasting blood glucose (FBG), serum total cholesterol (TC) and triglycerides (TG) were measured. Results: The overall prevalence of raised cholesterol and triglyceride levels were 25.97% (n=242) and 5.26% (n=49) respectively. The overall mean concentrations of TC and TG were 207.30± 54.18 mg/dL and 105.49 ± 51.22 mg/dL respectively. The population’s level of awareness of dyslipidemias was recorded at 0.77% (n=2), and no participant was on lipid-lowering drugs. The 40-64 years (OR:2.21, P<0.001) and ≥ 60 years (OR:2.19, P=0.006) age ranges, abdominal obesity (OR:1.76, P=0.026) and hypertriglyceridemia (OR:4.53, P<0.001) were independently associated with hypercholesterolemia, while the age range 40-64 years (OR:2.11, P=0.027), hypertension (OR:2.38, P=0.011) and hypercholesterolemia (OR:4.63,P<0.001) were independently associated with hypertriglyceridemia. Conclusion: The present study portrayed a high prevalence of elevated serum cholesterol level, a very low level of awareness and poor treatment coverage of dyslipidemias in the Ngaoundere population while reaffirming the relationships between advance age, abdominal obesity, hypertension and dyslipidemias.

Dislipidemia como factor de riesgo para enfermedad cerebrovascular: estudio de casos y controles / Dyslipidemia as risk factor for cerebrovascular disease: case-control study

Objetivo: Determinar si la dislipidemia es un factor de riesgo independiente para enfermedad cerebrovascular. Material y métodos: Se realizó un estudio de casos y controles pareados por edad y sexo. Los casos estuvieron conformados por pacientes con diagnóstico clínico y tomográfico de enfermedad cerebrovascular y los controles por pacientes con enfermedad distinta. A ambos grupos se les realizó dosaje sérico de colesterol total, LDLc y triglicéridos en las primeras 24 horas de su ingreso al hospital. Resultados: El total de pacientes estudiados fueron 160 (80 casos y 80 controles). La media para los casos fue de 64,92 ± 11,58 años y los controles 64,97 ± 11,42 años; el 63,75 % fueron del género masculino y 36,25 % del género femenino (p= 0,798, no significativo). La media de colesterol sérico, triglicéridos y LDLc en los casos fueron 191,4, 130,50 y 120,41 mg/dl y en los controles 210,16, 167,07 y 132,55; con p= 0,008, 0,001 y 0,060; respectivamente. El Odds ratio entre los casos y controles demuestra que la dislipidemia no incrementa el riesgo para enfermedad cerebrovascular (OR: 0,308). Conclusión: La dislipidemia no es un factor de riesgo independiente para enfermedad cerebrovascular.

Objetive: To determine whether dyslipidemia is an independent risk factor for cerebrovascular disease. Material and methods: A case-matched controls by age and sex was performed. The cases were composed of patients with clinical and tomographic diagnosis of cerebrovascular disease and controls for patients with different disease. Both groups underwent dosage serum total cholesterol, LDLcholesterol and triglycerides in the first 24 hours of admission to hospital. Results: A total of 160 patients were studied (80 cases and 80 controls). The average for cases was 64.92 ± 11. 58 years and 64.97 ± 11.42 years controls; 63.75% were of male and 36.25% females (p = 0.798, not significant). Mean serum cholesterol, triglycerides and LDL cholesterol in the cases were 191.4, 130.50 and 120.41 mg / dl; with p = 0.008, 0.001 and 0.060 in cases and controls respectively. The odds ratio between cases and controls demonstrated that dyslipidemia does not increase the risk for cerebrovascular disease (OR: 0.308). Conclusion: dyslipidemia is not an independent risk factor for cerebrovascular disease.

In vivo Evaluation of Hypolipidemic Potentials of Bacillus Species Isolated from Fermented Locust Bean (Parkia fillicoides Welw) Seeds (Iru).

Aim: Iru is a popular West Africa fermented soup condiment which is also consumed without cooking as snack. This product is mainly fermented by Bacillus species. The hypolipidemic activities of Bacillus spp. isolated from iru have not been documented hence the aim of this study. Place and Duration of Study: Iru sample was bought in an open market in Iworoko-Ekiti, Nigeria and transferred to the Laboratory of the Department of Microbiology, Ekiti State University, Nigeria where other studies were carried out. The study was conducted between January and June, 2012. Methodology: The properties and in vivo hypolipidemic potential of Bacillus species from iru were investigated using standard microbiological and haematological methods. Results: The cell free extracts of the Bacillus spp. did not produce significant inhibition on the selected Gram positive and Gram negative pathogens. Qualitative enzyme screening of the isolates showed all were haemolysin negative. Only B. subtilis was positive to gelatinase while all the isolates produced catalase and lipase. The average weight of the animals after inducement of hyper-cholesterolemia ranged between 60.5g - 95.3g. The amount of serum total cholesterol (TC) in the animals ranged between 124.9 mg/dl – 127.4 mg/dl while that of serum triglycerides (TG), high density protein (HDL) and low density protein (LDL) were 122.5 – 155.3 mg/dl, 10.0 – 15.3 mg/dl and 76.6 – 81.0 mg/dl respectively. The weights of hyper-cholesterolemia induced rats challenged with different species of Bacillus were relatively lower than those in the control group and also differ significantly from the control, at p˂ 0.05. The values of TC, TG, and LDL were highest in the control (saline) group while the values in the treatment group ranged between 121.3 ± 1.5 and 102.3 ± 6.8 mg/dl for TC. The treatment groups recorded lower values of values for TG (104.7 ± 1.6 - 117.4 ± 9.1 mg/dl) and LDL (42.6 ±7.4 - 59.0 ± 10.2 mg/dl) compared to the control. B. subtilis had the highest values of TC but least amount of LDL. TG in all the groups was higher than TC, HDL and LDL. The TC/HDL and the LDL/HDL of the animals in the iru group was higher than the other treatment groups but lower than the control. Conclusion: Compared to the control, hypolipidemic activities of B. lichenliformis was the best followed by B. subtilis. Iru had the least hypo-cholesterolemic effect.

The Specific Food Consumption Pattern and Blood Lipid Profiles of Korean Adults

Unlike studies of Europeans and Americans, many epidemiological studies of the Korean population have indicated that their risk for cardiovascular disease does not decrease with a vegetable-rich diet. The different dietary practices of Koreans, who consume salted vegetables instead of fresh vegetables (common in the Western diet), has been suggested as a reason for this observation. Korea is in a period of rapid epidemiologic transition, which includes dietary and disease patterns; therefore, this study investigated differences in the food consumption pattern and blood lipid profiles of Koreans compared to Europeans and Americans. The identification of dietary patterns related to blood lipid abnormalities was carried out using the 2007~2009 Korean National Health and Nutrition Survey data from 14,056 subjects. Dietary patterns were analyzed according to food group and nutrient intake. Blood lipid abnormalities were classified into three groups: hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterolemia (hypo-HDL-cholesterolemia). The prevalence of hypercholesterolemia, hypertriglyceridemia, and hypo-HDL-cholesterolemia was 12.4%, 16.2%, and 27.7% respectively. In our analysis, the low consumption of all food groups was related to hypercholesterolemia. The high consumption of vegetable-containing foods, alcoholic beverages, and the low consumption of milk products were associated with hypertriglyceridemia and hypo-HDL-cholesterolemia. Thus, unlike Europeans and Americans, the low consumption of all food groups is related to hypercholesterolemia and a low consumption of milk products is related to hypertriglyceridemia and hypo-HDL-cholesterolemia. Dietary pattern might play a role in epidemiologic transition of Korean. Also, this study implies necessity of further research using longitudinal data.

The Association of Plasma HDL-Cholesterol Level with Cardiovascular Disease Related Factors in Korean Type 2 Diabetic Patients / 당뇨병

BACKGROUND: Cardiovascular disease (CVD) is the major cause of death in type 2 diabetic patients. The purpose of this study was to investigate the characteristics of Korean type 2 diabetes mellitus (DM) patients according to plasma high density lipoprotein (HDL) cholesterol level and to document the effect of diet on HDL-cholesterol. METHODS: The subjects were 252 (male: 134, female: 118) Korean type 2 DM patients recruited from a general hospital's DM clinic and divided into low HDL-cholesterol group (male or = 40 mg/dL, female > or = 50 mg/dL). Anthropometric and hematological variables and dietary intake were assessed by the groups. RESULTS: The subject's mean age was 60.2 +/- 1.1 years and duration of diabetes was 9.5 +/- 1.0 years. Anthropometric measurements (body fat mass, % body fat, WHR, fat free mass, and muscle mass) and BMI were not significantly different between two groups. The male subjects with low HDL-cholesterolemia showed higher Atherogenic Index (AI, P < 0.001) and higher % carbohydrate from energy than control group (P < 0.01). The female subjects with low HDL-cholesterolemia showed higher AI (P < 0.001) and a tendency of higher triglyceride level and lower intake of energy, protein, lipid, vitamin B1 and vitamin E (P < 0.05) than control group. CONCLUSION: The subject with low HDL-cholesterolemia showed significantly higher AI. Male subject with low HDL-cholesterolemia consumed higher carbohydrate and female subject with low HDL-cholesterolemia showed lower intakes of many nutrients. This result suggests the importance of an adequate and balanced diet to manage type 2 DM patients to prevent CVD complications.
