OBJECTIVE: Rats fed diets enriched with fatty fish from the Amazon region had Hematology and plasma biochemistry analyzed. METHODS: Forty Wistar rats were divided into four groups: control group fed a standard diet; mapará group fed a diet enriched with Hypophthalmus edentatus; matrinxã group fed a diet enriched with Brycon spp.; and tambaqui group fed a diet enriched with Colossoma macropomum. After thirty days the rats had an red blood count and plasma biochemistry. RESULTS: Hematocrit and hemoglobin levels were higher in rats fed tambaqui and matrinxã than in those fed the standard diet of mapará. However, mapará increased cholesterol, especially low-density lipoprotein cholesterol and high-density lipoprotein cholesterol. All fish-enriched diets reduced triacylglycerols. CONCLUSION: Diets enriched with fatty fish from the Amazon region reduce triacylglycerol and increase high-density lipoprotein cholesterol, especially the diet enriched with tambaqui. Tambaqui and matrinxã affected hematocrit and hemoglobin levels, but not mapará. Further research is needed to determine the benefits of diets enriched with fatty fish from the Amazon region.

OBJECTIVE: The present study aimed to evaluate the effect of feeding diets enriched with fatty fish from the Amazon basin on lipid metabolism. METHODS: Male Wistar rats were divided into four groups: control group treated with commercial chow; Mapará group was fed diet enriched with Hypophthalmus edentatus; Matrinxã group was fed diet enriched with Brycon spp.; and, Tambaqui group was fed diet enriched with Colossoma macropomum. Rats with approximately 240g±0.60 of body weight were fed ad libitum for 30 days, and then were sacrificed for collection of whole blood and tissues. RESULTS: The groups treated with enriched diets showed a significant reduction in body mass and lipogenesis in the epididymal and retroperitoneal adipose tissues and carcass when compared with the control group. However, lipogenesis in the liver showed an increase in Matrinxã group compared with the others groups. The levels of serum triglycerides in the treated groups with Amazonian fish were significantly lower than those of the control group. Moreover, total cholesterol concentration only decreased in the group Matrinxã. High Density Lipoprotein cholesterol levels increased significantly in the Mapará and Tambaqui compared with control group and Matrinxã group. The insulin and leptin levels increased significantly in all treatment groups. CONCLUSION: This study demonstrated that diets enriched with fatty fish from the Amazon basin changed the lipid metabolism by reducing serum triglycerides and increasing high density lipoprotein-cholesterol in rats fed with diets enriched with Mapará, Matrinxã, and Tambaqui.

Pulmonary embolism (PE) is a fatal disease that arises from genetic and environmental factors. There is little evidence for low high-density lipoprotein cholesterol (HDL-C) with hyperhomocysteinemia to lead to PE. Therefore, we evaluated homocysteine levels and lipid profile in PE patients and to display risk for PE. Forty six patients with proven PE and 46 healthy controls were included in the study. Homocysteine and serum lipid levels were calculated and compared in both groups. There were no significant differences between two groups in terms of total cholesterol, triglyceride, and low-density lipoprotein cholesterol. In PE group, HDL-C levels were found significantly lower in comparison to the control group ( P = .004). Mean homocysteine levels were significantly higher in PE group than in the control group ( P = .001). High-density lipoprotein cholesterol levels were significantly low in which homocysteine levels were high in the PE group. We thought that low HDL-C level with hyperhomocysteinemia is susceptible to PE.

Abstract We evaluated the performance of a homogeneous assay for the automated measurement of high-density lipoprotein cholesterol (HDL-C) and compared it with a conventional precipitation technique in the following groups of people: control subjects (group A), clinically-healthy elderly (group B), myocardial infarction patients (group C), nephrotic syndrome patients (group D), and liver cirrhosis patients (group E). The performance of the technique was acceptable with respect to precision, accuracy, linearity, and detection limit. Triglycerides up to 40 mmol/L and bilirubin up to 150 μmol/L did not cause interferences. Hemoglobin decreased HDL-C measurements. Samples were stable at −20 °C for up to four months. Bland–Altman plots showed a good agreement between both techniques in the control group but with a progressive divergence in the patient groups B to E. Results indicate limitations of the technique in certain clinical conditions and, coincidentally, the need for reliable calibration materials.

AbstractPrevious studies have evidenced that inflammation and endothelial dysfunction have a crucial role in erectile dysfunction (ED). Increased monocyte count or activity and lower high-density lipoprotein cholesterol (HDL-C) levels have been associated with inflammation. The monocyte to HDL-C ratio (MHR) is a recently emerged indicator of inflammation. We aimed to investigate the relationship between MHR and ED. In this retrospective study, a total of 120 patients were enrolled, 60 of them having ED and 60 having a normal erectile function. The presence of ED was evaluated with the International Index of Erectile Function (IIEF-5). Patients with ED were compared with the control group for IIEF-5 and MHR. The mean ages of patients and controls were 55.6±5.53 and 56.42±6.63 years, respectively (p = 0.47). The risk factors for ED were similar between cases and controls. The total testosterone, glucose and creatinine levels did not differ between groups. While the HDL-C, LDL-C and triglyceride levels were similar between groups, the monocyte count (0.55±0.20 vs. 0.73±0.18, p < 0.0001) and MHR was significantly greater in patients with ED than in those without ED (1.31 vs. 1.77, p < 0.0001). MHR was significantly negatively correlated with IIEF-5 (p < 0.0001). To our knowledge, this is the first study that has shown a significant and independent association between elevated MHR and ED.

Sedentary, eumenorrheic women (N = 27) 22 to 40 years of age, with high baseline levels of plasma high-density lipoprotein cholesterol, were randomly assigned to a walking (n = 16) or a control group (n = 11). The training program involved treadmill walking 4.8 km (3.0 miles) four times a week for 40 weeks at a mean intensity of 72% maximal heart rate. Aerobic power (VO2max) was improved by 22%, but no training effect was observed in body composition variables or blood lipid/lipoprotein levels. Despite additional increments in exercise intensity over the final 20 weeks of training, most of the improvement in VO2max was observed over the first 20 weeks of the study. Exercising subjects' baseline levels of plasma HDL-C were found to be inversely associated with the change (delta) scores in the lipoprotein (r = −0.51, p <.05). Key words: maximal oxygen consumption, high-density lipoprotein cholesterol

Monocyte to high-density lipoprotein cholesterol ratio (MHR) is a systemic inflammatory marker, and recently, it has been used quite commonly for the assessment of inflammation in cardiovascular disorders. The aim of the present study is to investigate the relevance of MHR as a marker to assess metabolic syndrome (MetS) and MetS severity in clinical practice. A total of 147 patients with MetS who were diagnosed according to National Cholesterol Education Program Adult Treatment Panel III criteria and 134 healthy controls, matched for age and gender, were included in our retrospective study. MHR values were 13.15 ± 6.07 for patients with MetS and 9.74 ± 5.24 for the control group. MHR values of the patients were found to be statistically significantly higher than the control group ( P < .0001). MHR showed a significantly positive correlation with the severity of MetS ( r = .429; P < .0001). When patients with MetS were assessed with MHR in the study population, receiver–operating characteristic curve analysis yielded a cutoff value of 9.36 with a sensitivity of 72%, a specificity of 61%, and a P value <.0001. In logistic regression analyses of MetS with several variables, MHR remained as an independent predictor of MetS (95% CI: 0.721-0.945, P = .005). MHR might be an available and useful inflammatory marker to evaluate patients with MetS and disease severity.

Background: The associations of triglyceride (TG) to high-density lipoprotein cholesterol ratio (HDL‑C) and total cholesterol (TC) to HDL‑C ratio and low ankle brachial index (ABI) were seldom investigated. Patients and methods: A population based cross-sectional survey was conducted and 2982 participants 60 years and over were recruited. TG, TC, HDL‑C, and low-density lipoprotein cholesterol (LDL-C) were assessed in all participants. Low ABI was defined as ABI ≤ 0.9 in either leg. Multiple logistic regression models were applied to study the association between TG/HDL‑C ratio, TC/HDL‑C ratio and low ABI. Results: The TG/HDL‑C ratios for those with ABI > 0.9 and ABI ≤ 0.9 were 1.28 ± 1.20 and 1.48 ± 1.13 (P < 0.0001), while the TC/HDL‑C ratios were 3.96 ± 1.09 and 4.32 ± 1.15 (P < 0.0001), respectively. After adjusting for age, gender, body mass index, obesity, current drinking, physical activity, hypertension, diabetes, lipid-lowering drugs, and cardiovascular disease history, the odds ratios (ORs) with 95 % confidence intervals (CIs) of low ABI for TG/HDL‑C ratio and TC/HDL‑C ratio were 1.10 (0.96, 1.26) and 1.34 (1.14, 1.59) in non-smokers. When TC was further adjusted, the ORs (95 % CIs) were 1.40 (0.79, 2.52) and 1.53 (1.21, 1.93) for TG/HDL‑C ratio and TC/HDL‑C ratio, respectively. Non-linear relationships were detected between TG/HDL‑C ratio and TC/HDL‑C ratio and low ABI in both smokers and non-smokers. Conclusions: TC/HDL‑C ratio was significantly associated with low ABI in non-smokers and the association was independent of TC, TG, HDL‑C, and LDL-C. TC/HDL‑C might be considered as a potential biomarker for early peripheral arterial disease screening.
