The Effect of Blood Lipid Profiles on Chronic Kidney Disease in a Prospective Cohort:Based on a Regression Discontinuity Design

Objective Previous studies on the association between lipid profiles and chronic kidney disease(CKD)have yielded inconsistent results and no defined thresholds for blood lipids.Methods A prospective cohort study including 32,351 subjects who completed baseline and follow-up surveys over 5 years was conducted.Restricted cubic splines and Cox models were used to examine the association between the lipid profiles and CKD.A regression discontinuity design was used to determine the cutoff value of lipid profiles that was significantly associated with increased the risk of CKD.Results Over a median follow-up time of 2.2(0.5,4.2)years,648(2.00%)subjects developed CKD.The lipid profiles that were significantly and linearly related to CKD included total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),TC/HDL-C,and TG/HDL-C,whereas lowdensity lipoprotein cholesterol(LDL-C)and LDL-C/HDL-C were nonlinearly correlated with CKD.TC,TG,TC/HDL-C,and TG/HDL-C showed an upward jump at the cutoff value,increasing the risk of CKD by 0.90%,1.50%,2.30%,and 1.60%,respectively,whereas HDL-C showed a downward jump at the cutoff value,reducing this risk by 1.0%.Female and participants with dyslipidemia had a higher risk of CKD,while the cutoff values for the different characteristics of the population were different.Conclusion There was a significant association between lipid profiles and CKD in a prospective cohort from Northwest China,while TG,TC/HDL-C,and TG/HDL-C showed a stronger risk association.The specific cutoff values of lipid profiles may provide a clinical reference for screening or diagnosing CKD risk.

Effect of dates on blood glucose and lipid profile among patients with type 2 diabetes

Poor fruit and vegetable consumption is one of the 10 major risk factors for mortality.There is a misconception regarding the consumption of dates among patients with diabetes.This manuscript assessed the effects of date consumption on fasting and postprandial blood glucose,glycated hemoglobin,total cholesterol,triglycerides,low-density lipoproteins,high-density lipoproteins,and microbial markers.Four literature databases were searched for relevant articles.Of the 595 studies retrieved,24 assessed the effects of dates on glycemic control and lipids.Overall,the evidence suggests that dates have a lowering effect on blood glucose.Dates reduce total cholesterol and triglyceride levels and increase high-density lipoprotein levels.Dates also promote the abundance of beneficial gut microbiota.Therefore,patients with diabetes and dyslipidemia can consume dates to reduce their blood glucose,cholesterol,and triglycerides.

Improving a Patient’s CVD Risk Assessment—Updating the Interpretation of the Lipid Profile

The lipid profile remains an important laboratory assessment to prevent cardiovascular disease. Interpretation of the non-fasting lipid profile has significantly changed based on new information concerning the pathogenesis of atherosclerosis. In particular, the assessment of risk from cholesterol containing particles following triglyceride metabolism (termed remnant cholesterol) can now be done from a lipid profile. In addition, non-HDL cholesterol as calculated from the lipid profile will provide a complete assessment of total circulating cholesterol containing particles. Furthermore, the formula for measurement of LDL cholesterol from a lipid profile has now been revised so that triglyceride levels exert less interference. Finally, the old concept that the “higher the HDL-c, the better” is no longer tenable. New data indicate that the optimal high density lipoprotein level is below 100 mg/dl for both male and female patients. Correct interpretation of the lipid profile will optimize anti-atherosclerotic therapy and reduce the number one cause of death in the United States.

Lipid Profile of Patients Seen in Consultation at the Cardiology Department at the Ignace DEEN National Hospital (City of Conakry, Republic of Guinea)

The study addressed a crucial public health concern of dyslipidemia and its management, with a focus on the Ignace DEEN National Hospital patients, filling a research gap in the Republic of Guinea. It contributed valuable epidemiological data on dyslipidemia in the studied population, emphasizing gender, age, and socio-professional categories, which could inform tailored prevention and management strategies in improving the health care of dyslipidemia patients by proposing diets to help these patients better manage their disease and a food system for preventing dyslipidemia. The study focused on the lipid profile of patients seen at the cardiology department at the Ignace DEEN National Hospital Republic of Guinea (Conakry). This was a prospective, descriptive study lasting six (6) months from January 24 to July 23, 2021;aimed at determining the frequency of lipid abnormalities and pathologies related to the lipid profile. A total of 523 people were included in this study with a female predominance of 59.34% compared to 40.66% of males for a ratio of 1.5 in favor of women. The age groups of 45 - 54 and 55 - 65 were the most affected with respective frequencies of 45.42% and 30.03%. The most represented socio-professional category was that of housewives, i.e. 45.78%, followed by traders 18.68%. Our series was dominated by the married couple, i.e. 77.29%. Dyslipidemia constitutes a modifiable cardiovascular risk factor in patients seen in the cardiology department at the Ignace DEEN Hospital;its control must be strict through the use of hygienic and dietary rules and hypolipidemia medications.

Correlation between Serum CD36 Level and Lipid Profile in Patients with Type 2 Diabetes Mellitus, Khartoum State, Sudan

Background: Diabetes mellitus (DM) is a chronic metabolic disorder characterized by hyperglycemia. DM-related dyslipidemia are associated with complications resulting from progressive damage of various organs. CD36 is 88-kD, class B scavenger receptor, expressed on different types of cells. In diabetic patients, LDL particles are glycated with strong level;this increases CD36 expression, initiates foam cell formation and accelerates atherosclerosis. Objective: This study aimed to determine the correlation between serum CD36 level and lipid profile among patients with type 2 diabetes mellitus in Zeenam Specialized center, Khartoum State, Sudan, in a period between 2019 and 2022. Methodology: Hundred participants at different ages were included in this study;70 were type 2 diabetic patients (cases) and 30 apparently healthy individual (control). 3 ml of venous blood were collected from the participants by using a sterile needle and syringe into a labeled plain container. Each sample was stood until complete clot occurs. Clotted blood sample was then centrifuged to obtain the serum. Then they were used for measurement of total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride and soluble CD36 levels. Total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides were measured using Biosystem chemistry analyzer BTS-302. Serum CD36 was measured using Microplate Reader (URIT-660). Results: The results revealed that serum total cholesterol, LDL cholesterol, HDL cholesterol, and triglyceride levels were significantly higher in patients with type 2 diabetes mellitus compared with control (P = 0.03, P = 0.031, P = 0.000, P = 0.000) respectively, while there is no statistically significant differences in serum CD36 level between cases and control (P = 0.129). Also this study showed that there is no statistically significant correlation between serum CD36 level and total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, age and body mass index. Conclusion: This study concluded that there is no statistically significant difference in serum CD36 level between cases and control. And sCD36 level was not correlated with total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, body mass index, and age.

Body mass index and serum lipid profile influence serum prostate-specific antigen in Chinese men younger than 50 years of age

This study is to assess the potential factors that could affect the serum prostate-specific antigen （PSA） level in healthy younger men. We evaluated the associations of age, body mass index （BMI） and serum lipid profile with serum PSA level in 6774 Chinese men （aged 20-49 years） who received a routine health examination. Eligible men were classified into 10-year age groups, BMI was categorized as underweight （〈18.5）, normal （18.5-22.9）, overweight （23.0-24.9）, obese （25.0-29,9） and very obese （〉30） according to the redefined World Health Organization （WHO） criteria for the Asia-Pacific region. PSA levels were compared among groups as well, In multiple linear regression analysis, PSA was positively correlated with age （P〈0.0001）. Negative correlations existed between PSA and BMI （P〈0.0001） and triglyceride level （P=0.01）. No relationship could be found between PSA and serum cholesterol （P=0.711） or high-density lipoprotein （HDL; P =0.665）. In addition, we found that serum PSA levels increased with age and decreased with BMI. Our study demonstrates that age, BMI and triglyceride levels influence the PSA level in men 〈50 years of age.

High Physical Activity is Associated with an Improved Lipid Profile and Resting Heart Rate among Healthy Middle-aged Chinese People

Objective To investigate the effects of physical activity （PA） on dyslipidemia and elevated resting heart rate （RHR） in a large-scale cross-sectional study in China. Methods We recruited community-based individuals who were 40-60 years old using a cluster sampling method. The PA levels of the participants were classified as low, moderate, or high, using the International Physical Activity Questionnaire. Dyslipidemia was defined as the detection of abnormalities in lipid indicators, and 4 lipid parameters were evaluated using fasting blood samples. Multivariate logistic regression analyses were used to evaluate the associations of PA with dyslipidemia and RHR. Results A total of 10,321 participants （38.88% men） were included in this study. The percentages of individuals with high, moderate, and low PA levels were 46.5%, 43.9%, and 9.6%, respectively. In both men and women, high PA provided odds ratios of 0.88 [95% confidence interval （CI）： 0.83, 0.94] for dyslipidemia and 0.82 （95% CI： 0.73, 0.92） for elevated RHR, compared to participants with low PA. Conclusion Our data suggested that substantial health benefits （related to dyslipidemia and elevated RHR） occurred at higher intensity PA, with greater energy consumption, in middle-aged Chinese people, and particularly in men.

Helianthus tuberosus(Jerusalem artichoke) tubers improve glucose tolerance and hepatic lipid profile in rats fed a high-fat diet

Objective:To analyze the effects of feeding Helianthus tuberosus(HT) tubers on glucose tolerance and lipid profile in rats fed a high-fat diet(HFD). Methods:A normal HFD or HFD including 10 w/w% HT tubers(HFD + HT) was fed to F334/Jcl rats. After 10 weeks,organ weights,glucose tolerance,and lipid profile were analyzed. Results:The body weight,liver weight,and epidermal fat content in the HFD group were higher than those of the normal group,and similar to those of the HFD + HT group. The oral glucose tolerance test at 10 weeks revealed that the blood glucose level 30 minutes after beginning the test in the HFD + HT group was significantly lower than that in the HFD group. Liver triglyceride and total cholesterol levels in the HFD + HT group were significantly lower than those in the HFD group. Fecal triglyceride and total cholesterol levels in the HFD + HT group were higher than those in the HFD group. Histological analyses revealed that fat and glycogen accumulation increased in the HFD group,but decreased in the HFD + HT group. Conclusions:These results indicate that HT tubers have anti-fatty liver effects based on improvements in glucose tolerance and the hepatic lipid profile.

The Effect of Different Levels of Sesame Oil on Productive Performance, Egg Yolk and Blood Serum Lipid Profile in Laying Hens

Addition of sesame oil into layer diets has been proved to enrich the proportion of polyunsatu-rated fatty acids in animal’s products. In this study, the effects of different levels of sesame oil in the diets on the performance, egg yolk and blood serum lipid profile of Isa Brown laying hens were investigated. A total of 96 layers were assigned into 4 groups to receive either 1 of 4 different diets contained 0.0%, 1.5%, 3.0% and 4.5% sesame oil, respectively. Sample of 12 eggs obtained from each groups were assessed for egg quality. The egg yolk fatty acid profile was determined with gas chromatography. Results revealed that the higher levels of sesame oil in the diet decreased egg production, egg weight, and egg yolk color except feed conversion ratio. In addition, supplementation of sesame oil increased the flow index of the eggs and the Haugh unite. The egg yolk lipid profile was not significantly different in the sesame oil fed groups, whereas, compare to control, it decreased the level of cholesterol. The blood serum lipid profile decreased in the sesame oil groups compare to control group. Meanwhile, monoacildigliserol also decreased in the sesame addition groups. In parallel with increasing levels of sesame oil, monounsaturated fatty acid (oleic acid) in the egg yolks significantly increased compared to the control (37.00%, 42.89%, 42.20% and 43.48%, respectively). It can be implied that sesame oil supplementation into the laying hens diet is necessary to produce monounsaturated fatty acid (MUFA) enriched eggs.

Effects of Olive Oil and Grape Seed Oil on Lipid Profile and Blood Pressure in Patients with Hyperlipidemia: A Randomized Clinical Trial

Background and Aims: Hyperlipidemia is one of clear risk factors of diabetes. Regarding its importance, this study was designed to compare the effects of olive oil and grape seed oil on serum lipids and blood pressure in patients with hyperlipidemia in 2015. Methods and Results: In this clinical trial, 60 patients with hyperlipidemia who met inclusion criteria were recruited. Subjects were randomly assigned 3 groups: 1) consume 20 ml/day refined olive oil;2) consume 20 ml/day grape seed oil;3) the control group received no oil. The study period was six weeks. All participants were under Step I diet. Height and weight measurements were taken by Seca scale. Blood pressure, total cholesterol, high-density lipoprotein, triglyceride and fasting blood sugar were measured at baseline and after 6 weeks by standard methods. Low-density lipoprotein levels were calculated by the Friedewald’s formula. Data were analyzed with ANOVA test in SPSS software version 16.0. Sixty participants (36 female and 24 male) with the average age of 47.5 ± 9 y and the mean body mass index of 31.78 ± 5.41 kg/m2 had completed the study. Olive oil intervention decreased systolic blood pressure significantly compared to grape seed oil group (P = 0.01). Triglyceride was significantly decreased in olive oil and also triglyceride groups (P = 0.02 and 0.004, respectively). Conclusion: Overall, the effects of olive oil and grape seed oil were better than control group. However, we suggest the substitution of dietary lipids with olive oil because of its more beneficial effects.

Lipid Profile of Coronary Heart Disease Patients: A Prospective Observational Study

Background: Coronary heart disease (CHD) remains the major cause of mortality and morbidity in the entire world population despite therapeutic advances that control many risk factors. Lipid profile is regarded as an important factor in the development of coronary heart disease. There have been numerous studies confirming the association of hyperlipidemias with coronary heart disease in most of the Western as well as Asian countries of the world. But we have very little data on the relation between CHD and lipid profile. Aim of the Study: The aim of this study was to assess abnormal lipid levels and their association with coronary heart disease. Methods: This comparative observational study was conducted at the Department of Cardiology in M. Abdur Rahim Medical College, Dinajpur, Bangladesh from January 2019 to December 2019. Properly written consent was taken from all the participants before starting the main part of the investigation. Obeying inclusion and exclusion criteria of the study, a total of 131 participants were finalized as the study population. Among them, the Case Group was formed with 90 patients who had CHD, and with 41 healthy people, the Control Group was formed. All necessary data were collected, analyzed, and disseminated by several programs of MS-Office and SPSS version 23. Result: The study was conducted with 90 case group participants and 41 control group participants. Among the case group, 78% were male and 22% were female. Among the male case group participants, 44.29% were from 51 - 60 years of age, 35.71% were from 41 - 50 years of age and the rest 20% were above 60 years of age. On the other hand, among the female participants of Case Group, 45% were from 51 - 60 years of age, 30% from 41 - 50 years of age, and 25% were over 60 years of age. Regression analysis between the male and the female showed the P-value of 0.242. Serum cholesterol concentration and HDL concentration were significant between the Case and Control groups in all age groups and the P-value was <0.0001 in every age group. Triglyceride concentration was significant between the Case and Control groups in 41 - 50 and 51 - 60 years age groups with a P-value of <0.0001. But in the >60 years age group, we did not find any significant correlation and there the P-value was 0.478. LDL concentration between the groups showed significant correlations between the Case and Control groups in 41 - 50 and 51 - 60-years’ age groups where the P values were found, <0.0001 and 0.0002 respectively. But in the >60 years’ age group, we did not find any significant correlation and there the P- value was 0.515. Conclusion: In this study, it was found that the total cholesterol, triglycerides, HDL cholesterol, and LDL cholesterol concentrations were significantly higher in coronary heart disease (CHD) patients.

Anthropometric indices, lipid profile, and lipopolysaccharide-binding protein levels in metabolic endotoxemia: A case-control study in Calabar Metropolis, Nigeria

Objectives: To determine the anthropometric indices, lipopolysaccharide-binding proteins (LBP), and lipid profile in patients with metabolic endotoxemia. Methods: The study comprised of 47 patients with metabolic endotoxemia (the metabolic endotoxemia group) and 43 controls (the control group). Patients in the metabolic endotoxemia group were categorized further into three subgroups including the normal weight group (n=8), the overweight group (n=12) and the obese group (n=27). Height, weight, waist, and hip circumference were measured, and waist-hip ratio (WHR) and body mass index (BMI) were calculated. LBP was determined by ELISA and total cholesterol, triglycerides, high density lipoprotein by the respective enzymatic colorimetric methods. In addition, low density lipoprotein and very low density lipoprotein were determined by Friedewald's formula. Results: The mean waist circumference (WC), hip circumference (HC), BMI, total cholesterol, low density lipoprotein, and LBP of the metabolic endotoxemia group were significantly higher (P<0.05) than those of the control group. WHR, TG, high density lipoprotein and very low density lipoprotein of the metabolic endotoxemia group were not significantly different (P>0.05) from those of the control group. The mean WC, HC, WHR, and BMI of the obese group with metabolic endotoxemia were significantly higher (P<0.05) than those of the overweight group and the normal weight group with metabolic endotoxemia. Significant positive correlations were obtained between BMI and LBP (r=0.610, P=0.001), total cholesterol and LBP (r=0.385, P=0.007), TG and LBP (r=0.356, P=0.014) in patients with metabolic endotoxemia. Conclusions: Metabolic endotoxemia arising from increased circulating level of bacterial derive particles consequent to perturbation in the gut microbial community and the elevated ;serum level of LBP may precede the development of obesity, characterized by dyslipidemia, dysregulation of gut energy harvest, and metabolic energy imbalance.

Flavonoid-rich beverage effects on lipid profile and blood pressure in diabetic patients

AIM: To compare freeze-dried strawberry(FDS) beverage and strawberry-flavored drink effects on lipid profile and blood pressure in type 2 diabetic(T2D) patients.METHODS: In a randomized, double-blind, controlled trial, 36 subjects with T2D(23 females; mean ± SE age: 51.57 ± 10 years) were randomly divided into two groups. Participants consumed two cups of either pure FDS beverage(each cup containing 25 g freeze-dried strawberry powder equivalent to one serving of fresh strawberries; intervention group) or an iso-caloric drinkwith strawberry flavoring(similar to the FDS drink in fiber content and color; placebo group) daily for 6 wk. Anthropometric measurements, 3 d, 24 h dietary recall, and fasting blood samples were collected at baseline and at weeks 6 intervention. After lying down and relaxing for approximately 10 min, each participant's blood pressure was recorded in triplicate with 5 min intervals; recordings were made at baseline and the trial end-point. Each participant's lipid profile was assessed before and after intervention.RESULTS: Assessment at the weeks 6 intervention showed a significant reduction from baseline in total cholesterol levels and total cholesterol to high-density lipoprotein cholesterol(HDL-C) ratio in the intervention group(179.01 ± 31.86 to 165.9 ± 32.4 mg/L; P = 0.00 and 3.9 ± 0.88 to 3.6 ± 0.082 mg/L; P = 0.00 respectively), but the change was not significantly different between the two groups(P = 0.07, P = 0.29 respectively). Systolic blood pressure levels were significantly reduced from baseline in both the FDS and placebo drink groups(129.95 ± 14.9 to 114.3 ± 27.5 mm Hg; P = 0.02 and 127.6 ± 15.6 to 122.9 ± 14.47 mm Hg; P = 0.00 respectively), but the reduction was not significantly different between the two groups. Diastolic blood pressure was significantly reduced post-intervention in the FDS drink group compared to placebo group(78.7 ± 7.2 vs 84.4 ± 5.8; P = 0.01), the reduction was also significant within the FDS drink group(84.2 ± 8.03 to 78.7 ± 7.2; P = 0.00). Triglycerides, HDL-C concentrations and anthropometric indices showed no significant differences between or within groups. CONCLUSION: Short-term FDS supplementation improved selected cardiovascular risk factors in subjects with T2 D. Long-term effects on other metabolic biomarkers need to be investigated in future trials.

Evaluation of Lipid Profile in Obese and Non-Obese Hypertensive Adult Patients Attended in Medicine Department of a Medical College Hospital of Bangladesh

Background: By the dawn of this modern era of science, the prime challenge of physician is cardiovascular disease (CVD). The most important modifiable risk factors of CVDs are unhealthy diet, physical inactivity and tobacco use. The effects of unhealthy diet and physical inactivity include abnormal blood lipid, obesity and hypertension. We tried to evaluate and correlate the pattern of lipid profile in obese and non-obese hypertensive patients. Objectives: This study was conducted at medicine department of Cumilla Medical College Hospital. The principal aim was to evaluate the lipid profile in obese and non-obese adult hypertensive patients. Methodology: During this cross sectional analytical study, a total of 100 adult hypertensive patients were taken by purposive sampling. Among them 50 (group 1) patients were taken those were obese and 50 (group 2) patients taken those were non-obese according to BMI measurement on operational definition. Diagnosis of hypertension would be established with the help of ambulatory BP measurements two occasions few minutes apart. The staging of hypertension was done according to JNC7 Criteria. Morning blood samples were taken after 8 - 12 hours of fasting and lipid profiles were done on authentic laboratories. The laboratory values were interpreted according to the operational definition of dyslipidaemia. The ethical research and review committee approved the study protocol and signed informed consent was obtained from the participants. The statistics was analyzed using the IBM SPSS software of version 19.0. Statistical significance was set at p < 0.05. Results: Among the two groups, there were 56 (56%) males and 44 (44%) females. The mean age of group 1 (46.10 ± 11.09) was compared to that of group 2 (45.5 ± 10.6). Lipid profile abnormalities were significantly higher in the stage 2 hypertension (59.62%) and stage 3 hypertension (66.66%), higher in class 2 obese (100%) and class 3 obese subjects (100%), female hypertensive patients had significantly higher BMI than their male counterparts (27.24 ± 3.63 kg/m2 versus 29.29 ± 3.99 kg/m2), lipid profiles were higher in the female than male hypertensive patients (63.33% vs 55.35%) but only TC was statistically significant (4.45 ± 1.19 mmol/l versus 4.86 ± 1.29 mmol/l, p < 0.05). Those who were obese had significant high TG (p < 0.001), high TC (p < 0.001) and high LDL-C (p < 0.001). 38 (76%) of the obese hypertensive patients had dyslipidaemia whereas 21 (42%) of non-obese hypertensive patients had dyslipidaemia. In multivariate regression, TG was significantly and directly associated with BMI of subjects. Dyslipidaemia was more prevalent in the age group 30 - 59 of adult hypertensive patients. It showed that obese hypertensive patients had significantly higher SBP (p < 0.001), DBP (p < 0.001) than non-obese subjects. The mean TC (4.83 ± 0.95 mmol/l versus 4.15 ± 0.57 mmol/l, t = -9.70, p < 0.001), TG (2.64 ± 0.67 mmol/l versus 2.10 ± 0.45 mmol/l, t = -5.37, p < 0.001) and LDL-C (3.00 ± 0.82 mmol/l versus 2.44 ± 0.53 mmol/l, t = -9.11, p < 0.001) were also significantly higher among the hypertensive obese subjects. The mean HDL-C was however comparable in the two groups (1.25 ± 0.27 mmol/l versus 1.24 ± 0.57 mmol/l, t = -0.25, p = 0.08)...

Comparison of Serum Lipid Profile between Gestational Diabetes Mellitus and Pregnant Women with Normal Glucose Tolerance

Background: Aberrant lipid metabolism presumed to have important relationship with gestational diabetes mellitus (GDM), though previous studies revealed inconsistent results on this area. Objectives: To identify the difference of serum lipid profile between gestational diabetes mellitus (GDM) and pregnant woman with normal glucose tolerance (NGT). Methods: This cross sectional study was conducted from January 2017 to December 2017 at Department of Endocrinology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh with 31 GDM and equal number of NGT pregnant women diagnosed on the basis of WHO criteria-2013, during 24 - 40 weeks of gestation. Glucose was measured by glucose oxidase method and fasting serum lipid profile [Total cholesterol (TC), High Density Lipoprotein-cholesterol (HDL-C) and Triglyceride (TG)] was measured by enzymatic-colorimetric method. Data were analyzed and compared by statistical tests. Results: Among total sixty-two (62) study subjects, 31 were GDM (age: 27.52 ± 4.8 years, body mass index (BMI): 27.17 ± 3.3 kg/m2) and 31 were pregnant women with NGT (age: 24.94 ± 4.2 years, BMI: 25.43 ± 6.5 kg/m2). Mean age of GDM group was significantly higher than that of NGT group (p = 0.028). Women with GDM showed relatively higher BMI than NGT women but that was not statistically significant (p = 0.194). Fasting lipid profiles between GDM and NGT (GDM vs. NGT;total cholesterol: 194.21 ± 42.18 vs. 208.52 ± 42.18 mg/dl, p = 0.187;HDL-C: 47.50 ± 16.17 vs. 47.18 ± 11.71 mg/dl, p = 0.928;LDL-C: 109.25 ± 28.80 vs. 119.30 ± 34.76 mg/dl, p = 0.220 and triglyceride 204.78 ± 58.50 vs. 202.34 ± 79.18 mg/dl, p = 0.891) were not significantly different. The variations in all lipid fraction values were not statistically significant among GDM women when analyzed between BMI groups holding BMI cut-off at 23 kg/m2. No significant differences of any values of lipid profile were found in GDM women according to various age categories (Age < 25 years vs. ≥25 years). Conclusions: Lipid profile does not differ between women with GDM and pregnant woman with NGT.

Sex Hormones Affect Aging Process by Influencing Lipid Profiles, Cellular Immunological Function and Lipid Peroxides and Oxidation System

Objectives To investigate the correlation between sex hormones(SH) and aging. Methods Through epidemiological investigation in our country, the levels of SH were measured by radioimmunoassy; lipid profile, glucose and apolipoprotein by automatic biochemic analytical instrument; T cell subsets by flow cytometer; and MDA, SOD were evaluated by the thiobarbituric acid (TBA) test and the nitrite method modified by Oyanagui respectively using spectrophotometry. Results In men, the serum levels of follicle stimulating hormone ( FSH)、luteinizing hormone(LH) increased significantly with aging, but serum prolactin(PRL) and progesterone(P) levels remained unchanged in all life; Both testosterone (T) and free testosterone (FT) all decreased greatly with aging, but 17β - estradiol( 17β - E_2) was reverse ; E_2 was negatively correlated with T and E_2/T increased with aging. The level of serum total cholesterol (TC) increased with aging, but triglycerides (TG) remain unchanged; compared with young group, high - density lipoprotein cholesterol ( HDL - C) ; HDL - C/TC of other groups decreased significantly, but low - density lipoprotein cholesterol ( LDL - C ) changed inversely; HDL- C/LDL- C reduced slightly with aging and showed no difference between groups. Apolipoprotein A1 (apoA1) and apoB all enhanced greatly with aging; meanwhile the ratio of apoA1/apoB decreased. The concentration of serum glucose (GLU) was unchanged in all life. To compare with those in the young group, CD3 + , CD4 + in other groups reduced greatly, CD4 + remained unchanged. Meanwhile, CD8 + increased significantly with aging. Compared with the young group, serum malondialdehyde(MDA) value of the old ones increased obviously, but the activity of superoxide dismutase(SOD) was reverse. By partial correlation analysis (controlling BMI, FSH, LH and PRL), TC、 LDL-C、apoA1、apoB、CD8 + 、MDA of men all presented a positive correlation with E_2/T respectively, their correlation coefficients (γ) were 0. 262、0. 136、 0. 532、0. 379、0. 394、0. 234 (P < 0. 001 ) ; HDL - C、 HDL- C/TC、HDL- C/LDL- C、CD3 + 、CD4 +/CD8 + 、SOD showed a negatively correlation with E_2/T respectively, γequaled - 0.563、- 0.332、- 0.654、- 0.1530、-0.4140、-0.236(P<0.001). In women, the serum concentrations of FSH、LH increased significantly after menopause; PRL increased little with aging; compared with young group, E_2 and P in postmenopausal groups reduced obviously, E_2/P revealed significant reduce with aging. T enhanced significantly after menopause, but nor did FT. E_2, P and the ratio of E_2/P were negatively correlated with age respectively by bivariate correlation analysis, and a positive relation between T and age. After 70 years old, the level of TC increased obviously, and so did that of TG after menopause; HDL decreased with aging, but LDL increased after 70, with the result that the ratios of HDL- C/TC and HDL- C/LDL- C all reduced with aging; apoA1 decreased gently after 70, but apoB increased signifi- cantly after menopause; correspondingly, the ratio of apoA1/apoB declined obviously. The concentration of GLU increased with aging. CD3 + and CD4 + didn't change until 60, but reduced after 60. Compared with the young groups, CD8 + remained unchanged, CD4 +/CD8 + reduced greatly with aging, CD4 + and CD8 + presented a negatively correlation with age respectively. The value of MDA in serum of women increased notably after 70 years old, but SOD activity already decreased significantly from 60. By partial correlation analysis (controlling BMI, FSH, LH and PRL), HDL-C、CD4 +、CD4 +/CD8 + showed a certain correlation with E_2/P respectively; γ were 0. 245、 0.157、0. 154 ( P <0.05 ) ; TG、 LDL、 apoB、 apoA1/ apoB、SOD presented a negatively correlation with E_2/P respectively, γ were 0. 452、 0. 236、 0.321、 0. 135、 0.156、0.154、0.426 ( P < 0.05 ). Conclusions The Disequilibrium of SH had correlations with lipid profile, cellular immunological function and lipid peroxides and oxidation system; these suggested SH took an important role in the process of aging.

Effect of Egyptian Date Palm Pollen (Phoenix dactylifera L.) and Its Hydroethanolic Extracts on Serum Glucose and Lipid Profiles in Induced Diabetic Rats

Diabetes is a major health global problem that has reached alarming levels. The present study aims for studying the effect of date palm pollen (Phoenix dactylifera L.) El-Hayani cultivar on serum glucose and lipids profile in induced diabetic male albino rats. Palm pollen chemically analyzed besides chemical constituents, mineral contents, polyphenols and flavonoids. Male Albino rats (36 rats weight 170-190 gm) were divided into 6 groups. 1: Normal control (-), 2: Alloxanized diabetes control (+) (150 mg/Kg rat body weight). Diabetic groups 3 and 4 had 0.5%, 1.0% date palm pollen, respectively, also diabetic groups 5 and 6 had 100 ppm, 200 ppm date palm pollen extract, respectively. At the end of the experiment (4 weeks) rats were fasted overnight and anesthetized and blood samples were taken for analysis of serum glucose, lipids profile and renal-hepatic function parameters, relative organ weight data obtained are statistically analysis. Results showed that the major polyphenolic components were that e-vanillic acid (16.33 mg/100 g), pyrogallol (15.02 mg/100 g), epicatechin (11.04 mg/100 g), catechin (10.96 mg/100 g). While, date palm pollen was rich in hesperidin (8.84 mg/100 g), Kaempferol 3,2 p-coumaroyl glucose (6.92 mg/100 g), hesperitin (5.10 mg/100 g), rutin (3.11mg/100 g) as flavonoids components. Date palm pollen has high content of protein, calcium and iron (30.87 g/100 g, 510.82 and 236.50 mg/100 g), respectively. Also, serum glucose decreased significantly in diabetic groups (3, 4, 5 and 6, respectively) (179.47, 137.80, 156.77, 145.47 mg/100 mL, respectively). Lipids profile, renal and liver functions were improved significantly (P < 0.05) in diabetic groups which had date palm pollen or its extracts. It is concluded that the dried date palm pollen 1% in the diet and 200 ppm extract are more effective compared with controlling diabetes mellitus, also improve renal and liver functions. Diabetics are advised to eat date palm pollen and are considered treatment foods for Diabetes Mellitus.

Serum monoterpene levels, glucose homeostasis, lipid profiles, and metabolic syndrome in adults: NHANES, 2013–2014

Monoterpenes are organic compounds which have been studied for their medicinal benefits.However,the association between monoterpene exposure and metabolic parameters in humans is unknown.We investigated the connection between three specific monoterpenes(α-pinene,β-pinene,and limonene),glucose homeostasis biomarkers,lipid profiles,and metabolic syndrome(MS)in 1627 adults from the National Health and Nutrition Examination Survey(NHANES)2013–2014.We found serum levels ofα-pinene andβ-pinene were positively associated with fasting glucose,total cholesterol,triglyceride,and apolipoprotein B.In addition,increased levels of limonene andΣmonoterpene(sum of three monoterpene chemicals)were linked to higher insulin,β-cell function,total cholesterol,low density lipoprotein cholesterol(LDL-C),triglycerides,and apolipoprotein B.Participants with all three monoterpenes above the 50th percentile had notably higher values for total cholesterol and triglycerides compared to those with all three monoterpenes below the 50th percentile(P for trend<0.001).Regarding MS,higher serum concentrations ofα-pinene were linked to an increased risk of high-density lipoprotein cholesterol(HDL-C)insufficiency and hypertriglyceridemia.Elevated concentrations ofβ-pinene were associated with a higher prevalence of hypertriglyceridemia.Moreover,increased levels of limonene andΣmonoterpene were connected to a higher risk of MS,larger waist circumference,low HDL-C,hypertriglyceridemia,and higher blood pressure according to MS criteria.In conclusion,serum monoterpenes levels were linked to glucose regulation,lipid profiles,and indicators of MS.Further studies are necessary to clarify the potential causal relationships.

Vitamin C and E supplementation and high intensity interval training induced changes in lipid profile and haematological variables of young males

High intensity interval training(HIIT)causes oxidative stress and haematological alteration.Present study was aimed to evaluate the effect of 8 weeks’supplementation of vitamin C and E on HIIT induced changes in lipid profile parameters and haematological variables.Hundred six male adolescent players were randomly assigned into five age-matched groups,i.e.,Control(no exercise+placebo),HIIT(placebo),HIIT+vitamin-C(1000mg/day),HIIT+vitamin-E 400 IU/day)and combined HIIT+vitamin C and E.Morning and evening sessions(90min)of HIIT included 4 phases(15min each)with 3 sets(4min each).Each 4min HIIT set consisted of 2min intense sprint workout(90%–95%of heart rate maximum[HRmax])followed by 1min active recovery(60%–70%HRmax)followed by 1min of complete rest(1:1 work-rest ratio).Lipid profile parameters,haematological variables,endurance capacity and vertical jump were evaluated by standard protocols.Significant decrease in body weight,fat%,total cholesterol,triglyceride,Total Cholesterol/High Density Lipoprotein-Cholesterol and significant increase in High Density Lipoprotein-Cholesterol,maximal oxygen consumption,vertical jump were observed for all four intervention groups.White blood cell count,red blood cell count,haemoglobin percentage and haematocrit values were significantly decreased while platelet count and platelet-to-leukocyte ratio(PLR)ratio were increased significantly only for HIIT group.Blood level of tocopherol and ascorbic acid was significantly increased(values were within the normal range)in all the respective vitamin supplemented groups.Supplementation of vitamin C and E secures health protection with suppressed haemolysis and improved inflammatory blood variables with enhanced explosive leg strength and lipid profile parameters without any concomitant change in endurance capacity.
