RESUMO

The history of studying hypertriglyceridemia as a risk factor for atherosclerosis has been going on for a half a century. The significance of this parameter as measured in fasting state is not entirely clear, since the statistical significance between triglyceride concentration and cardiovascular risk is lost after adjustment to HDL-cholesterol concentration. Remnant particles of chylomicrons and very low density lipoproteins measured postprandially appear to be responsible for the risk associated with hypertriglyceridemia. As the concentration of non-fasting triglycerides increases, the risk of myocardial infarction increases gradually up to five times.

RESUMO

The aim of this study is to investigate the acute and chronic effects of aerobic training performed indoors and outdoors on irisin, adropin, and cholesterol levels in winter. Thirty-two healthy males participated in this study. Participants were divided into two groups: outdoor group (n = 16) and indoor group (n = 16). They then performed 40-min aerobic running exercises 4 days/week for 18 weeks. The outdoor group trained at -5°C-5°C environmental temperature, while the indoor group trained at 21°C-25°C. Blood samples were collected before and after the 18-week training period and immediately after the first training. The results showed that single aerobic exercise induced minimal increase in serum irisin concentrations in both groups. In addition, irisin levels did not change in the outdoor group but significantly decreased in the indoor group after the 18-week training period. Aerobic exercise had no acute or chronic effects on serum adropin levels in the indoor group. However, the aerobic training caused a decrease in adropin levels chronically, but there was no acute effect after single aerobic exercise in the outdoor group. Furthermore, there was no acute effect on high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, and total cholesterol after single aerobic exercise in both groups. However, after the 18-week training period, there was a significant increase in HDL-C levels in both groups. Moreover, the increase in HDL-C in the outdoor group was higher than in the indoor group. Thus, this study provides evidence for the beneficial chronic effects of aerobic exercise and cold on HDL-C levels as well as the beneficial acute effects on irisin concentrations.

RESUMO

Pregnancy is accompanied by changes in the maternal lipoprotein metabolism that may serve to satisfy the nutritional demands of the fetus in addition to the energy requirements of the mother. Early pregnancy is considered the anabolic phase, characterized by increased hepatic production of triglycerides and enhanced removal of triglycerides from the circulation, resulting in an increased deposition of fat in maternal adipose tissue. Late pregnancy is referred to as the catabolic phase, the release of free fatty acids from adipocytes is enhanced due to both relative insulin resistance and stimulation of hormones. Although it is known that cholesterol rises in pregnancy, at present it is not routinely measured or treated. However, a growing body of evidence from animal and human studies suggests adverse consequences of high cholesterol levels in pregnancy. High lipid profile, a major factor behind atherosclerosis may leads to unconsciousness. To avoid such problems during pregnancy this longitudinal study was carried out in the department of Biochemistry, Mymensingh Medical College in co-operation with the Department of Obstetrics and Gynecology, Mymensingh Medical College Hospital and Community Based Medical College Hospital, Bangladesh from July 2011 to December 2012 to compare the changes in high density lipoprotein cholesterol level during 2nd and 3rd trimester of pregnancy. A total of one hundred subjects were participated in this study comprising of second and third trimester of pregnancy. All subjects were made to fast overnight at least for a minimum of 8 hours. Blood samples were taken and analyzed by enzymatic colorimetric kit method. Pregnancy has been found to be associated with changes in lipid profile and this differs with each trimester. The average results were analyzed with respect to each pregnancy for the whole group. The study proves that serum High Density Lipoprotein (HDL) cholesterol increases in second trimester (48.71±7.61mg/dl) than third trimester (47.01±7.45mg/dl) of Pregnancy. So, Lipid profile estimation and monitoring should be made as a part of routine investigation during antenatal period.

RESUMO

Cardiovascular diseases are among the main causes of mortality worldwide, and dyslipidemia is a principal factor risk. Hence the study of biochemical markers is necessary for early diagnosis. OBJECTIVES: Evaluate biomarkers to diagnose the risks of cardiovascular diseases in healthy Brazilian and African young adults. DESIGN & METHODS: Weight, height, waist circumference, percentage of body fat and systemic blood pressure were measured; and fasting blood samples were taken for biochemical analysis. Triglycerides, total cholesterol, HDL-c, and apolipoproteins A-I and B were measured on automated equipment using commercially available kits, in addition to the tests of antioxidant capacity of HDL and the enzymatic activity of Paraoxonase 1. RESULTS: After statistical analysis, it was found that BMI, WC, fat (%), triglycerides, ApoB/ApoA-I ratio and Vmax were higher in Brazilians, while HDL-c, ApoA-I, Lag Time, Vmax and PON1 activity were higher in Africans. In Brazilians, the ApoB/ApoA-I ratio was related to obesity factors and lipid profile, but in Africans it was related only to lipids. The antioxidant capacity of HDL and PON1 activity was better in Africans. Through independence testing, we observed an association with moderate risk of myocardial infarction with gender in Africans. In the binary logistic regression analysis, it was found that men in general - and particularly African men - have higher risk of myocardial infarction than women; Odds Ratio 2144 (CI95%: 1343-3424) and 2281 (CI95%: 1082-4811), respectively. CONCLUSIONS: The anthropometric and biochemical parameters of Brazilians, especially men, predispose them to greater risks of cardiovascular diseases.

RESUMO

INTRODUCTION AND OBJECTIVE: There is a significantly higher risk of lipid disorders occurrence, including atherogenic dyslipidemia in women after menopause than it is in general population. The aim of the work was to investigate the correlation between health behaviours and the occurrence of lipid disorders in women after menopause working in agriculture. MATERIAL AND METHODS: The study was conducted in years 2015-2016 and included 843 post-menopausal women working in agriculture. The following were used: a questionnaire including socio-demographic data, laboratory lipid tests, inventory of health behaviours. The following were estimated: logistic regression models for serum lipids concentration versus frequency of health behaviours in the examined women. RESULTS: Adverse lipid profile was found in over a half of post-menopausal women working in agriculture, whereas the frequency of health behaviours were estimated at the average level, although the frequency of correct eating habits and health practices was significantly lower than preventive behaviours and positive psychological attitudes. A correlation was found between the frequency of health behaviours and the occurrence of lipid disorders in women after menopause working in agriculture: more frequent health practices co-existed with the lower concentration of total cholesterol and a higher concentration of HDL-cholesterol, more frequent preventive behaviours co-existed with lower concentration of LDL-cholesterol. Women with higher concentration of triglycerides undertook pro-health practices relatively more often. CONCLUSIONS: The study revealed a high prevalence of lipid disorders in postmenopausal women working in agriculture. More effective health education programmes are necessary in the area of reduction the risk factors of CVD in the population of women working in agriculture.

RESUMO

Introduction: High Density Lipoproteins (HDL) are dysfunctional in hypercholesterolemia patients. The hypothesis was tested that nicotinamide (NAM) administration will influence HDL metabolism and reverse cholesterol transport from macrophages to the liver and feces in vivo (m-RCT) in a murine model of hypercholesterolemia. Methods: Apolipoprotein E-deficient (KOE) mice were challenged with a high-fat diet for 4 weeks. The effect of different doses of NAM on cholesterol metabolism, and the ability of HDL to promote m-RCT was assessed. Results: The administration of NAM to KOE mice produced an increase (∼1.5-fold; P < 0.05) in the plasma levels of cholesterol, which was mainly accounted for by the non-HDL fraction. NAM produced a [3H]-cholesterol plasma accumulation (∼1.5-fold) in the m-RCT setting. As revealed by kinetic analysis, the latter was mainly explained by an impaired clearance of circulating non-HDL (∼0.8-fold). The relative content of [3H]-tracer was lowered in the livers (∼0.6-fold) and feces (> 0.5-fold) of NAM-treated mice. This finding was accompanied by a significant (or trend close to significance) up-regulation of the relative gene expression of Abcg5 and Abcg8 in the liver (Abcg5: 2.9-fold; P < 0.05; Abcg8: 2.4-fold; P = 0.06) and small intestine (Abcg5: 2.1-fold; P = 0.15; Abcg8: 1.9-fold; P < 0.05) of high-dose, NAM-treated mice. Conclusion: The data from this study show that the administration of NAM to KOE mice impaired m-RCT in vivo. This finding was partly due to a defective hepatic clearance of plasma non-HDL

RESUMO

Both low and very high levels of high-density lipoprotein cholesterol (HDL-C) increase the risk of atherosclerotic cardiovascular disease (ASCVD) and shorten life expectancy. Low and high levels of HDL­C are often caused by underlying diseases, lifestyle or medication, which should primarily be excluded. Much less frequently, monogenic diseases due to mutations in the APOA1, ABCA1 and LCAT genes are the cause of very low or unmeasurable HDL­C levels or in the CETP, LIPC and SCARB1 genes for very high HDL­C values. Genetic and detailed biochemical diagnostics should be considered, especially in cases of absolute HDL deficiency, early onset ASCVD or the presence of clinical symptoms or laboratory values characteristic for deficiencies of apolipoprotein A­I (ApoA-I), lecithin cholesterol acyltransferase (LCAT) or Tangier disease. These included corneal opacities, xanthomas, large tonsils, hepatomegaly, peripheral neuropathy, proteinuria, anemia or thrombocytopenia. Sequencing of the APOA1 gene should also be considered in familial amyloidosis. There is no specific treatment for monogenic HDL diseases. Cholesterol and blood pressure lowering are indicated for the prevention of cardiovascular and renal complications.

RESUMO

Carotid intima-media thickness (C-IMT) increases in patients with adult type-2 diabetes mellitus (DM) and is used for early detection of macrovascular complications. We aimed to investigate the change of C-IMT in prediabetes and type-2 DM patients compared to subjects with normal glucose metabolism (NGM).A total of 180 individuals (60 subjects with NGM, 60 patients with prediabetes and 60 patients with type-2 DM) were included in this study. Routine laboratory and micro-macrovascular involvement were investigated. Urine albumin-creatinine ratio (ACR) was measured for urinary albuminuria detection. In addition to routine laboratory examination, right-left common and internal C-IMT (CC-IMT and IC-IMT) were measured.Systolic and diastolic blood pressure values were found to be higher in prediabetes and type-2 DM groups than NGM group. The prevalence of nephropathy and presence of CAD were higher in type-2 DM groups than prediabetes. Glucose, glycated hemoglobin (HbA1c), total cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, blood urea nitrogen, creatinine, high sensitive C reactive protein (hs-CRP) levels and urinary ACR were significantly higher in patients within prediabetes and type-2 DM groups than NGM group. Glucose, HbA1c and hs-CRP levels were found to be higher in type-2 DM groups than prediabetes. Estimated glomerular filtration rate and high-density lipoprotein (HDL) cholesterol level was found to be lower in patients within prediabetes and type-2 DM groups than NGM group. Right-left-mean CC-IMT and IC-IMT values were found to be higher in prediabetes and type-2 DM groups than NGM group. Left IC-IMT, left CC-IMT, and mean IC-IMT values were found to be higher in type-2 DM patients compared to prediabetes. LDL and HDL cholesterols, HbA1c, and hs-CRP levels were independently associated with IC-IMT and CC-IMT.C-IMT values were significantly higher in impaired glucose metabolism compared to NGM. C-IMT measurement may be used as part of routine screening of macrovascular complication in patients with prediabetes and newly diagnosed type-2 DM.

RESUMO

BACKGROUND: The prevalence of abdominal obesity is increasing worldwide. Adults with abdominal obesity have been reported to have increased risk of cardiometabolic disorders. The aim of this study was to examine whether non-obese subjects (body mass index (BMI) < 25 kg/m2) with abdominal obesity examined in the framework of the Swiss-Hungarian Cooperation Programme had increased metabolic risk compared to participants without abdominal obesity. METHODS: A cross-sectional study was carried out in 5228 non-obese individuals. Data were collected between July 2012 and February 2016. Descriptive statistics, Pearson's correlation analysis and multiple logistic regression models were applied, odds ratios (OR) with 95% confidence interval (CI) being the outcomes. RESULTS: 607 (11.6%) out of the 5228 non-obese individuals had abdominal obesity. The correlation analysis indicated that the correlation coefficients between BMI and waist circumference (WC) were 0.610 in males and 0.526 in females. In this subgroup, the prevalence of high systolic blood pressure, high fasting blood glucose, and high total cholesterol and triglyceride levels were significantly higher. The logistic regression model based on these data showed significantly higher risk for developing high systolic blood pressure (OR = 1.53; 95% CI = 1.20-1.94), low HDL cholesterol (OR = 2.06; 95% CI = 1.09-3.89), and high trygliceride level (OR = 1.65; 95% CI = 1.27-2.16). CONCLUSIONS: There was a very high, significant, positive correlation between WC and BMI. Abdominal obesity was found to be strongly related to certain metabolic risk factors among non-obese subjects. Hence, measuring waist circumference could be recommended as a simple and efficient tool for screening abdominal obesity and related metabolic risk even in non-obese individuals.

RESUMO

Hyperuricemia has received increasing attention as a major public health problem. This study aims to investigate the risk factors for hyperuricemia and to explore the relationship between changes in biochemical variables and incident hyperuricemia.A cross-sectional and subsequently prospective study was performed among adults who took their health checkups at Zhejiang University Hospital. The participants who were free of hyperuricemia at baseline received annual follow-up examinations during a 6-year period. Cox proportional hazards regression analyses were conducted to calculate the risks for incident hyperuricemia.Of the 9238 participants enrolled, 1704 (18.4%) were diagnosed as hyperuricemia. During 21,757 person-years of follow-up, 1492 incident hyperuricemia cases were identified. The incidence of hyperuricemia was 68.58 cases per 1000 person-year of follow-up in the overall participants. The prevalence and the incidence of hyperuricemia increased greatly in female older than 50 years. High levels of BMI, SBP, FPG, TG, LDL-C, ALT, BUN, and creatinine increased the risk of hyperuricemia. Suffering fatty liver also increased the risk of hyperuricemia. Subjects with increasing DBP, TG, BUN, creatinine, or decreasing HDL-C were more likely to incident hyperuricemia.This study revealed that the change of diastolic blood pressure (DBP), serum triglycerides (TG), blood urea nitrogen (BUN), creatinine, and high-density lipoprotein cholesterol (HDL-C) level were independently associated with incident hyperuricemia.

RESUMO

OBJECTIVE: To analyze the prevalence of altered total cholesterol and fractions levels in the Brazilian population, according to biochemical data from the National Health Survey. METHODS: A descriptive study, using data from the National Health Survey, collected between 2014 and 2015. Total cholesterol and fractions were analyzed and population prevalences of altered values according to socio-demographic variables were calculated. The cutoff points considered were: total cholesterol ≥ 200mg/dl; low-density lipoprotein LDL ≥ 130mg/dL and high-density lipoprotein HDL < 40mg/dL. RESULTS: The prevalence of total cholesterol ≥200mg/dL in the population was 32.7%, and higher in women (35.1%). The prevalence of altered HDL was 31.8%, 22.0% in females and 42.8% in males. LDL ≥ 130mg/dL was found in 18.6% and was higher in women (19.9%). The population aged 45 years old and older and those with low levels of education presented a higher prevalence of altered cholesterol. CONCLUSION: Altered values of total cholesterol and fractions were frequent in the Brazilian population, especially among women, the elderly and people with low levels of education. These results may guide control and preventative actions such as healthy eating, physical activity and treatment, all of which aim to prevent coronary diseases.

RESUMO

Recently, studies have shown significant association between the rs2000999 polymorphism in the haptoglobin-encoding gene (HP) and low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) levels, which are important risk factors for cardiovascular diseases. However, the association of rs2000999 with serum lipids in Latin American diabetic populations is still uncharacterized. Here, we analyzed the association of rs2000999 with TC, high-density lipoprotein cholesterol (HDL-C), and LDL-C levels in 546 Mexican adults with type 2 diabetes (T2D) and in 654 controls without T2D. In this observational case-control study we included adults from 4 centers of the Mexican Social Security Institute in Mexico City recruited from 2012 to 2015. TC, HDL-C, LDL-C, triglycerides (TG), and glucose levels were measured by an enzymatic colorimetric method. The variant rs2000999 was genotyped using TaqMan real time polymerase chain reaction. The percentage of Native-American ancestry showed a negative association with the rs2000999 A allele. In contrast, the rs2000999 A allele had a strong positive association with European ancestry, and to a lesser extent, with African ancestry. Linear regression was used to estimate the association between the variant rs2000999 and lipid concentrations, using different genetic models. Under codominant and recessive models, rs2000999 was significantly associated with TC and LDL-C levels in the T2D group and in controls without T2D. In addition, the group with T2D showed a significant association between the variant and HDL-C levels. In summary, the rs2000999 A allele in Mexican population is positively associated with the percentage of European and negatively associated with Native American ancestry. Carriers of the A allele have increased levels of TC and LDL-C, independently of T2D diagnosis, and also increased concentrations of HDL-C in the T2D sample.

RESUMO

BACKGROUND: Extra virgin olive oil (EVOO) has shown beneficial effects on the lipid profile and inflammatory parameters in general population. Our goal is to analyze these changes together with those of intestinal microbiota in human immunodeficiency virus (HIV)-infected patients over 50 years of age. METHODS: Experimental single arm open study. HIV patients over the age of 50 with undetectable viral load were selected. EVOO was distributed among the patients so that each one consumed 50 g daily for 12 weeks. Lipid profile, C-reactive protein (CRP), and intestinal microbiota composition were analyzed at the beginning and at the end of the intervention. RESULTS: Total cholesterol decreased significantly (5 mg/dL), and a nonsignificant decrease in low-density lipoprotein cholesterol (12 mg/dL), triglycerides (21 mg/dL), and CRP (1.25 mg/dL) was observed. There was a significant increase in alpha diversity after the intervention in men and a decrease in proinflammatory genera such as Dethiosulfovibrionaceae was observed. Differences were also observed in the microbiota of men and women and according to the type of antiretroviral treatment. CONCLUSION: Sustained consumption of 50 g of EVOO in elderly HIV-infected patients might be associated with an improvement in lipid profile and alfa diversity of intestinal microbiota.

RESUMO

Dyslipidemia has been described in sickle cell anemia (SCA) but its association with increased disease severity is unknown. Here, we examined 55 children and adolescents with SCA as well as 41 healthy controls to test the association between the lipid profiles in peripheral blood and markers of hemolysis, inflammation, endothelial function, and SCA-related clinical outcomes. SCA patients exhibited lower levels of total cholesterol (P<0.001), low-density lipoprotein cholesterol (LDL-c) (P<0.001), and high-density lipoprotein cholesterol (HDL-c) (P<0.001), while displaying higher triglyceride (TG) levels and TG/HDL-c ratio values (P<0.001). TG/HDL-c values were positively correlated with lactate dehydrogenase (P=0.047), leukocyte count (P=0.006), and blood flow velocity in the right (P=0.02) and left (P=0.05) cerebral artery, while being negatively correlated with hemoglobin levels (P<0.04). Acute chest syndrome (ACS) and vaso-occlusive events (VOE) were more frequent in SCA patients exhibiting higher TG/HDL-c values (odds ratio: 3.77, P=0.027). Multivariate logistic regression analysis confirmed independent associations between elevated TG/HDL-c values and SCA. Thus, children and adolescents with SCA exhibited a lipid profile associated with hemolysis and inflammatory parameters, with increased risk of ACS and VOE. TG/HDL-c is a potential biomarker of severity of disease.

RESUMO

Recently, the monocyte count to high-density lipoprotein cholesterol ratio (MHR) was found to be associated with the SYNTAX score in patients with both stable coronary artery disease (CAD) and acute coronary syndrome (ACS). The MHR was significantly higher in male patients. However, the sex-specific association of MHR with SYNTAX score in stable CAD was not well explored. Thus, the present study aimed to investigate the association of MHR and presence and severity of CAD evaluated by coronary angiography and the SYNTAX score in males and females.In total, 873 patients who received selective coronary angiography between March 2017 and July 2018 were included in the present study. Patients were divided into 3 groups according to MHR tertiles. The MHR was calculated by dividing the monocyte count by the high-density lipoprotein cholesterol level. CAD was defined as at least 50% diameter stenosis of a major coronary artery, including the right coronary, left main coronary, left anterior descending, and left circumflex arteries. The SYNTAX score was calculated by 2 experienced interventional cardiologists. SYNTAX score ≥23 was defined as a high SYNTAX score.Males showed a significantly higher MHR (12.2 [8.9-15.5] vs 9.3 [6.2-12.1], P < .001), accompanied by a higher prevalence of CAD (68.1% vs 53.4%, P < .001). Male sex remained an independent predictor of elevated MHR after correction for confounding factors (adjusted odds ratio [OR] 3.102, P = .001). The association between MHR and SYNTAX score was confirmed only in male stable patients with CAD (r = 0.113, P = .036). Multivariate logistic regression analysis showed that MHR was an independent predictor of SYNTAX score ≥23 only in male patients with CAD. The receiver-operating characteristic curve showed a predictive value of MHR for high SYNTAX score only in males.A higher MHR in males and a positive correlation of MHR with SYNTAX score were observed only in male stable patients with CAD. Such an easily obtained index may help interventional cardiologists detect high-risk patients before coronary catheterization, but its application may be restricted to males.

RESUMO

O presente manuscrito teve por objetivo a revisão de literatura sobre os efeitos do destreinamento (DT) no sistema cardiovascular e em fatores de risco cardiovasculares, tais como massa corporal, adiposidade e perfil lipídico. Para isso, uma ampla pesquisa da literatura nas bases de dados PubMed, Scopus e Web of Science foi realizada, e o conjunto de dados mostrou que o DT promove reversão das adaptações cardiovasculares obtidas com o treinamento físico, tais como redução do VO2máx, do débito cardíaco máximo, do volume sistólico, do volume sanguíneo e da massa ventricular. Além disso, o DT induz aumento da frequência cardíaca de repouso e submáxima, da resistência vascular periférica e da pressão arterial. O curso temporal para que tais efeitos cardiovasculares ocorram é amplo, podendo ocorrer a partir da segunda semana de DT até três meses após o DT. O DT também gera prejuízos aos fatores de risco cardiovasculares, tais como aumento da massa corporal e da adiposidade, aumento do colesterol total, LDL e VLDL, e redução do HDL. Enquanto os efeitos na massa corporal aparecem após quatro semanas de DT, as mudanças no perfil lipídico são mais precoces, com apenas uma semana de DT


The objective of this manuscript is to review the literature about the effects of detraining (DT) on the cardiovascular system and on cardiovascular risk factors such as body mass, adiposity and lipid profile. For this, a wide literature search in the PubMed, Scopus and Web of Science databases was performed, and the data showed that DT promotes the reversal of cardiovascular adaptations obtained with physical training, such as reduction in VO2 max, cardiac output, ejection fraction, blood volume and ventricular mass. In addition, DT induces an increase in resting and submaximal heart rates, peripheral vascular resistance and blood pressure. The timeframe for such cardiovascular effects to be seen is long, which may occur from the second week of DT to 3 months after DT. DT also causes damage to cardiovascular risk factors by inducing an increase in body mass and adiposity, an increase in total cholesterol, LDL and VLDL, and a reduction in HDL. While effects on body mass appear after 4 weeks of DT, changes in lipid profile appear earlier, with only 1 week of DT

RESUMO

Patients with mental disorders are more susceptible to cardiovascular diseases and metabolic disorders compared to the general population. Objective: To evaluate cardiovascular risk and metabolic syndrome in individuals with mental disorders. Materials and methods: A cross-sectional study, conducted at the Psychosocial Care Centers. Socioeconomic, clinical, biochemical and anthropometric data were collected using a standard form. Cardiovascular risk was assessed by the Framingham risk score. Metabolic syndrome (MS) was determined by the World Health- Organization (WHO), the National Cholesterol Education Program (NCEP) and the International Diabetes Federation (IDF) criteria. Data were analyzed by descriptive statistics, and associations were evaluated by the chi-square test and Fisher's exact test, as well as Odds Ratio. The significance level adopted for all statistical tests was 5%. Results: The chance of individuals diagnosed with MS be at intermediate-to-high cardiovascular risk was greater (12.22, 8.01 and 6.23 times higher according to WHO, NCEP and IDF criteria, respectively) than those without MS. Conclusion: A high percentage of patients with mental disorders were at intermediate / high cardiovascular risk, and this was significantly associated with MS

RESUMO

Microplastics (MPs) are highly concerned environmental pollutants that are ubiquitous in the environmental and might affect human and animal health. In this study, we exposed pregnant mice to 0.5 and 5 µm with 100 and 1000 µg/L polystyrene MPs, then investigated maternal MPs exposure during gestation and evaluated the potential effects on the mice offspring (PND42). In the F1 offspring, the serum triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) levels and hepatic TC, TG levels were altered, while some of them were only significant in 5 µm MPs-treated group. Various serum metabolites including amino acids and acyl-carnitines were carried out by nonderivatized tandem mass spectrometry, there were 11 and 15 kinds of metabolites changes significantly in 0.5 and 5 µm MPs-treated groups, respectively. Furthermore, the changes of C0 and C0/(C16 + 18) indicators suggested the potential risk of fatty acid metabolism disorder, which was verified by hepatic genes expression. These results indicated that maternal exposure of two different sizes of polystyrene MPs increased risks of metabolic disorder in their offspring, and greater effects were observed in 5 µm MPs-treated groups. The data provides a preliminary exploration of the potential relationship between MPs and the risk metabolic disorder even in the next generation, which might offer new insights into the health risk assessment of MPs.

RESUMO

Objectives: Individual with diabetes may have several from of Dyslipidemia. Dyslipidemia has been considered to be factor that plays a risk in progression of micro vascular disease, especially in diabetes.1 The present study is intended to Study of correlation between Apolipoprotein B and Dyslipidemia in type 2 diabetes patients and prevalence of dyslipidemia in type 2 diabetic patients. Material and Methods: Prospective cross- sectional study conducted on 100 cases of type 2 diabetes mellitus. Groups are divided according to A/C ratio and association of dyslipidemia was seen. Serum Apolipoprotein B was measured using immunoturbidimetric method. Results: Pearson's correlation analysis of Apo B with lipid parameters in diabetic patients showed that, LDL, TC and Tg were positively correlated with Apo- B. There was a positive and linear correlation between LDL and Tg. Apo- B was negatively correlated with HDL-C. Conclusion: The majority of patients studied had low HDL-C, elevated non HDL- C, elevated total cholesterol, elevated triglycerides, elevated LDL -C and elevated apo B. Apolipoprotein B had a positive linear correlation with total cholesterol, triglycerides, LDL-C, non-HDL-C. The strongest positive correlation was with nonHDL-C. Patients with low HDL-C had high apo B levels.

RESUMO

A low serum high-density lipoproteins-cholesterol (HDL-C) level is a risk factor of cardiovascular disease and dementia. On the other hand, no study has elucidated the correlation between household income and the HDL-C level in the adult population. In the present study, 5535 subjects (20-80 year-old individuals) were selected from the Korean national health and nutrition examination survey 2017 (KNHANES VII-2, n = 2469 men, n = 3066 women). They were classified into five levels of household income grades ranging from one (the lowest) to five (the highest). They were also classified according to the HDL-C level: category 1 (<40 mg/dL, n = 943), category 2 (40-49 mg/dL, n = 1764), category 3 (50-59 mg/dL, n = 1572), category 4 (60-69 mg/dL, n = 820), and category 5 (≥70 mg/dL, n = 436). Generally, in both genders, a higher HDL-C level is associated with a larger percentage of income grades 4 and 5. Moreover, the lowest HDL-C group showed the largest percentage of income grade 1. In both groups, a significant increase in the average income grade was associated with a concomitant increase in the HDL-C level (men, p = 0.03, women, p < 0.001). In the low HDL-C category, a lower income grade is associated directly with a lower HDL-C level, which suggests that poverty is associated directly with a low HDL-C. Women showed a 3.3-fold higher incidence of dementia than men did at later-life. The sharp decrease in HDL-C in the female group older than 50 was accompanied by a dramatic increase in the incidence of dementia. However, the male group showed a relatively mild decrease in the HDL-C level after mid-life and weak elevation in the incidence of dementia. In conclusion, in both genders, the lower income group showed a larger prevalence of low-HDL-C levels. The decrease in HDL-C after middle age was strongly associated with the considerable increase in dementia in later-life.
