Objective: To investigate whether serum bisphenol A (BPA) concentration is related to the occurrence of dyslipidemia. Methods: A total of 574 adults were enrolled at baseline and followed up for 5 years. Concentrations of serum BPA, triglycerides (TGs), low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol were measured. Dyslipidemia was defined as the existence of one or more of the following conditions: high-LDL-cholesterolemia (LDL ≥140 mg/dL), hypertriglyceridemia (TGs ≥150 mg/dL), or low-HDL-cholesterolemia (HDL <40 mg/dL). Participants were stratified into tertiles according to low, median, and high baseline serum BPA levels. Multivariable linear and logistic regression models were used. Data from baseline and follow-up were used for cross-sectional and longitudinal analyses, respectively. Results: In the cross-sectional analysis, compared to subjects in the low BPA tertile, those in the high BPA tertile showed a higher level of LDL cholesterol (108.1 ± 24.4 mg/dL versus 119.5 ± 26.9 mg/dL; P<.05) and a lower level of HDL cholesterol (46.2 ± 11.7 mg/dL versus 39.5 ± 7.5 mg/dL; P<.05). In multivariable linear regression models, Z-transformed BPA was positively associated with LDL cholesterol (β= 0.13, P = .002) and negatively associated with HDL cholesterol (β= −0.28; P<.001). After cross-sectionally adjusting for confounders, subjects in higher BPA exposure was associated with a higher prevalence of low-HDL-cholesterolemia. Longitudinally, in subjects without low-HDL-cholesterolemia at baseline, each SD increment in baseline BPA was associated with a higher incidence of low-HDL-cholesterolemia after adjustment for confounders (odds ratio [95% confidence interval; CI] 2.76, 95% CI 1.21, 6.29). Conclusion: Cross-sectionally, higher BPA exposure is associated with a higher prevalence of low-HDL-cholesterolemia. Longitudinally, baseline BPA is an independent predictor of the 5-year incidence of low-HDL-cholesterolemia.

SummaryPlatelet aggregation, platelet lipid composition and plasma lipoprotein concentrations were measured each week in a group of seventeen alcoholics, without overt liver disease, for one month, following acute, total alcohol withdrawal. The platelets were initially hypoaggregable but, within 1-2 weeks of cessation of drinking, they became hyperaggregable and then gradually returned towards normal values. Hyperaggregability could not be explained by increases in either the cholesterol or the arachidonic acid content of the platelets. Plasma very-low-density lipoprotein cholesterol levels remained high throughout the study, but the initially raised levels of high-density lipoprotein (HDL) cholesterol fell by 26%. Low-density lipoprotein (LDL) cholesterol concentration rose by 10% after two weeks of withdrawal but then returned to about the starting level. The resulting changes in the plasma LDL-cholesterol: HDL-cholesterol ratio, which had increased by more than 50% after two weeks of abstinence, essentially paralleled the time course of enhanced platelet reactivity in all but four of the alcoholics. These findings suggest that alterations in plasma lipoprotein concentrations during acute alcohol withdrawal may be a contributory factor to the haemostatic disorders present in such patients.

Blood samples were taken from 12 goats during the periparturient period (4 and 1 weeks before and 2, 10 and 30 days after delivery), and from 10 nonpregnant goats. The following variables were determined: total lipids (TL), triacylglycerol (TG), total cholesterol (TCH) and high-density lipoprotein (HDL) cholesterol and low-density lipoprotein (LDL) cholesterol fractions. One week before delivery TL (2.32 ± 0.12 g/l, P ≤ 0.05), TG (0.32 ± 0.16 mmol/l, P ≤ 0.001) and TCH concentrations (1.65 ± 0.42 mmol/l, P ≤ 0.05) were significantly increased as compared to non-pregnant goats (2.08 ± 0.28 g/l, 0.15 ± 0.05 mmol/l, 1.38 ± 0.19 mmol/l, respectively). After delivery, the concentrations of TL, TG, TCH and HDL decreased significantly. The lowest TG concentration was observed 2 days after delivery (0.18 ± 0.02 mmol/l), while TL (1.73 ± 0.21 g/l), TCH (0.95 ± 0.21 mmol/l) and HDL (0.74 ± 0.16 mmol/l) reached the lowest level 10 days after delivery. Two days after delivery a significant increase of LDL concentration was observed (0.38 ± 0.04 mmol/l); however, ten days after delivery a threefold decrease was shown in the LDL concentration (0.12 ± 0.04 mmol/l). A month after delivery all the variables studied reached levels similar to those measured in non-pregnant goats.

The purpose of this research was conducted to evaluate the effects of daun wungu extracts to decrease total cholesterol, LDL (Low Density Lipoprotein) and HDL (High Density Lipoprotein) cholesterol of ovariectomized mice. This research used 24 ovariectomized mice and 8 normal mice. The ovariectomized mice were grouped in 3 groups for K1 (the treatment with aquadest, 0.05 ml), K2 (the treatment with fish oil, 0.05 ml) and P (the treatment with daun wungu extracts, 0.5 mg in 0.05 ml fish oil). All treatments were done for 20 days. At the end of the treatments, the blood (0.5 ml) was taken from cardiac by tuberculin disposable syringe. And then with fotometry, serum total, LDL and HDL cholesterol were measured. The result of this research showed that daun wungu extracts (0.5 mg in 0.05 ml fish oil) could not decrease HDL cholesterol, but it could decrease total and LDL cholesterol of blood serum in ovariectomized mice.

Background The prevalence of smoking in adolescentstends to increase. Smoking is associated with a higher risk ofdyslipidemia.Objective To compare the lipid profiles of tobacco-smoking andnon-tobacco-smoking male adolescents.Methods We performed a cross- sectional study in three vocationalhigh schools in Yogyakarta from January to April 2011. Dataon smoking status, duration of smoking and number cigarettesconsumed per day were collected by questionnaires. We randomlyselected 50 male smokers and 50 male non-smokers as the studysubjects.Results Mean differences between smokers and non-smokerswere 44.5 (95%CI 28. 7 to 60.1) mg/dL for triglyceride levels; 8.0(95% CI 1.0 to 14.9) mg/dL for low density lipoprotein (LDL)cholesterol; 11.8 (1.1 to 22.4) mg/dL for total cholesterol and -5.7mg/dL (95% CI -8.8 to -2.6) for high density lipoprotein (HDL)cholesterol. Mean differences (95% CI) between smokers whohad engaged in smoking for > 2 years and those who had smokedfor :S:2 years were -18.1 (95% CI -33 .9 to -2.3) mg/dL for totalcholesterol; -49.4 (95% CI -67.2 to -3 1.5) mg/dL for triglycerides.Mean differences between those who smoked > 5 cigarettes/dayand :s:5 cigarettes per day were -18 .4 (95% CI -32.8 to -4.1) mg/dL for total cholesterol and -29.1 (95% CI -53.6 to -4.6) mg/dLfor triglycerides.Conclusion Smoking more than 5 cigarettes/day significantlyincreases total cholesterol, LDL cholesterol, and triglyceridelevels, as well as reduces HDL cholesterol levels; while smokingmore than 2 years significantly increases total cholesterol andtriglyceride levels

Objective: Serum low density lipoprotein (LDL) cholesterol is considered as the primary target of lipid lowering therapy and non-high density lipoprotein (HDL) cholesterol is the recommended second target. Recent studies claimed that non-HDL cholesterol is a better predictor of cardiovascular diseases (CVD) than LDL cholesterol. In this study we aimed to compare non-HDL cholesterol and LDL cholesterol as a CVD risk factor in confirmed diabetic subjects. Materials and methods: In this cross-sectional observational study, 1042 confirmed diabetic subjects selected randomly were included. HbA1cResults: In the total subjects, 767 (74%) subjects had LDL cholesterol > 100 mg/dL and 822 (79%) subjects had non- HDL cholesterol > 130 mg/dL. HbA1c values were different (p<0.02) in five groups and showed upward trend (p<0.01). All the lipid parameters studied were significantly different in five groups (p<0.0001) and TC, TG and non-HDL cholesterol showed upward trend (p<0.0001), but HDL cholesterol and LDL cholesterol showed downward trend (p<0.0001). Odds ratio (OR) of likelihood of risk individuals regarding non-HDL cholesterol compared to LDL cholesterol were 0.50 (p<0.001), 1.32 (p>0.05), 2.96 (p<0.001), 6.49 (p<0.001) and 9.37 (p<0.001) for TG concentrations of up to 150 mg/dL, 151-200 mg/dL, 201-250 mg/dL, 251-300 mg/dL and 301-400 mg/dL respectively with relative risk of 0.60, 1.24, 2.43, 4.83, 5.10. Conclusion: LDL cholesterol is a better tool for the detection of high-risk individuals than non-HDL cholesterol at TG concentration up to 150 mg/dL, whereas non-HDL cholesterol is better than LDL cholesterol at TG concentration above 200 mg/dL as a CVD risk factor.

Aims: The aim of this study was to investigate associations between psychosocial work exposure and the presence of biological and imaging biomarkers of cardiovascular disease. Methods: This cross-sectional study was conducted in a sub-cohort of the Swedish CArdioPulmonary bioImage Study (SCAPIS). Psychosocial exposure was evaluated with the job demand–control model, and analysed according to the standard categorization: high strain, active, passive and low strain (reference). Biomarkers (blood pressure, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol, coronary artery calcification (CAC) and metabolic syndrome) were measured, or derived through measurements, from clinical examinations. Gender-specific prevalence ratios (PRs) and 95% confidence intervals (CIs) were calculated with regression models and adjusted for age, education, smoking, physical activity, general life stress and body mass index (BMI). Results: The analyses included 3882 participants (52.5% women). High strain (high demands–low control) was linked to increased PR for low HDL cholesterol in women, adjusted for all covariates (PR 1.76; 95% CI 1.25–2.48). High strain was also related to moderately increased PR for metabolic syndrome in men, after adjustments for all covariates except BMI (PR 1.25; 95% CI 1.02–1.52). In addition, passive work (low demands–low control) was associated with diastolic hypertension in women (fully adjusted: PR 1.29; 95% CI 1.05–1.59). All relationships between psychosocial factors and LDL cholesterol or CAC (both genders), or hypertension (men), were non-significant. Conclusions: Poor psychosocial job conditions was associated with the presence of low HDL cholesterol and diastolic hypertension in women, and metabolic syndrome in men. These findings contribute to the knowledge of potential pathways between stressful work and coronary heart disease.

Abstract We analyzed the susceptibility of low-density lipoproteins (LDL) to oxidation in 17 healthy smokers (43.3 +/- 16.8 pack-years) and 19 healthy nonsmokers, matched for age (smokers: 52 +/- 7 years; nonsmokers: 53 +/- 7 years), gender, and relative body mass. Cholesterol, triglycerides, LDL cholesterol, HDL cholesterol, and apolipoprotein (apo) B were not different between smokers and nonsmokers; apo A-I was slightly lower in smokers (one-tailed P = 0.066). To study whether LDL from smokers were prone to in vitro oxidation than LDL from nonsmokers, we measured the time kinetics of diene formation and the production of malondialdehyde during oxidation of LDL in vitro. In smokers and nonsmokers, respectively, the mean (+/-SD) lag times (tinh) of diene formation were 111 +/- 26 and 100 +/- 27 min, the peak rates of diene formation (Vmax) were 5.99 +/- 2.34 and 6.34 +/- 2.30 mmol x min-1 x g-1, and the amounts of dienes produced during the propagation phase (dmax) were 250 +/- 264 and 248 +/- 56 mmol x g-1. Neither the malondialdehyde content of LDL (measured as thiobarbituric acid-reactive substances) before oxidation nor the amount of malondialdehyde generated during oxidation (smokers: 57.0 +/- 14.2 micromol x g-1; nonsmokers: 63.2 +/- 15.2 micromol x g-1 indicated any statistically significant effect of smoking. When nonsmokers and smokers were considered together, the amount of malondialdehyde generated during oxidation correlated with age (nonparametric rs = 0.405), body mass index (r2 = 0.573), and concentrations of apo B (rs = 0.480), cholesterol (rs = 0.448), triglycerides (rs = 0.436), and LDL cholesterol (rs = 0.398). Our data show that smoking is not associated with increased oxidizability of LDL in healthy men and women at ages 42-63 years.

Bezafibrate (Bezalip - MCP), an analogue of clofibrate (Atromid-S), has been marketed in the UK for two years. Like clofibrate 1 it lowers both triglyceride and total cholesterol levels in plasma. The reduction is usually in low-density lipoprotein (LDL) cholesterol, whilst high-density lipoprotein (HDL) cholesterol rises. Like other lipid-lowering drugs, it should be used only where appropriate dietary measures have failed and where the hyperlipidaemia poses a significant risk.2

1. Changes in serum total and lipoprotein fraction triglyceride and cholesterol levels were studied in 24 adults on home haemodialysis. Half the patients were randomly allocated to a low cholesterol (mean 200 mg/day), fat-modified diet (mean polyunsaturated/saturated fat ratio of 1.0 with a mean of 43% of the total energy content derived from fat). 2. Before dietary manipulation, triglyceride levels in all lipoprotein fractions were significantly higher (P < 0.02) than in a control group of age and sex matched normal subjects. Total cholesterol, very-low-density-lipoprotein (VLDL) and low-density-lipoprotein (LDL) cholesterol were also significantly raised (P < 0.02), but high-density-lipoprotein (HDL) cholesterol was normal. In the patients on a fat-modified diet triglyceride levels did not alter in any of the lipoprotein fractions. Total cholesterol and LDL cholesterol levels fell significantly into the normal range (P < 0.002 and < 0.001 respectively) but VLDL and HDL cholesterol levels did not change. 3. Hypertriglyceridaemia is the most common lipid abnormality in patients with renal failure and a long-term fat-modified diet is, therefore, of limited therapeutic importance in these patients unless there is a low HDL/LDL cholesterol ratio.
