Effects of alpha lipoic acid on iron overload, lipid profile and oxidative stress indices in β-thalassemia major patients: A cross-over randomised controlled clinical trial.

β-Thalassemia major (β-TM) is associated with iron overload, abnormal lipid levels and oxidative stress. Alpha lipoic acid (ALA) showed anti-oxidant and iron chelating properties, but its effect in β-TM patients is unclear. We investigated the effects of ALA on iron levels, lipid profile and oxidative stress. In this cross-over randomised clinical trial, 26 β-TM patients were assigned to receive 600mg/d ALA or placebo (corn starch), for 8weeks with a 21-days washout period. Serum ferritin, total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), LDL-C/HDL-C, total antioxidant capacity, malondialdehyde (MDA) and MDA/LDL-C were assessed at baseline and the end of each intervention phase. Twenty-two patients completed the study. Serum ferritin (P=.004), MDA (P=.025) and MDA/LDL-C ratio (P=.002) were decreased and HDL-C (P=.035) increased significantly during ALA consumption. In comparison with placebo, ALA decreased the serum ferritin significantly (P=.02). Also, the changes in serum ferritin between ALA and placebo (-123.1±40.0 vs -34.3±21.0, P=.03) was significant in women subgroup. ALA had no significant effects on the other biomarkers. The results of this study indicated that supplementation with 600mg/d ALA may decrease serum ferritin in β-TM. Further studies are needed to confirm the findings.

Elevated lipids are associated with reduced regional brain structure in youth with bipolar disorder.

Abnormal blood lipid levels are common in bipolar disorder (BD) and correlate with mood symptoms and neurocognition. However, studies have not examined the lipid-brain structure association in BD or youth. This study examined low-density lipoprotein (LDL-C), high-density lipoprotein (HDL-C), triglycerides, and total cholesterol (TC) levels in relation to brain structure utilizing T1-weighted images, among participants ages 13-20 with BD (n=55) and healthy controls (HC; n=47). General linear models investigated group differences in the association of lipids with anterior cingulate cortex (ACC), hippocampus, and inferior parietal lobe structure, controlling for age, sex, body mass index, and intracranial volume. For significant associations, post hoc within-group analyses were undertaken. Exploratory vertex-wise analyses further investigated group differences in the lipid-brain structure association. There were significant group differences in the association of LDL-C (β=-0.29 p=0.001), and TC (β=-0.21 p=0.016), with hippocampal volume, and triglycerides with ACC volume (β=-0.25 p=0.01) and area (β=-0.26 p=0.004). Elevated lipids were associated with smaller brain structure to a significantly greater extent in BD vs HC. Post hoc analyses revealed that elevated LDL-C (β=-0.27 p=0.007) and reduced HDL-C (β=0.24 p=0.01) were associated with smaller hippocampal volume in the BD group. Exclusion of BD second-generation antipsychotic users did not alter these results. Vertex-wise analyses further showed that elevated lipids were associated with smaller brain structure to a significantly greater extent in BD vs HC, across the cortex. Elevated lipids are associated with smaller brain structure in BD. Research evaluating lipid-brain structure associations prospectively and whether lipid optimization has salutary effects on brain structure is necessary.

BACKGROUND Dyslipidaemia has been proposed as a possible risk factor for diabetic retinopathy (DR) but results from previous studies are inconsistent. We designed this study to find the association of abnormal serum lipid levels with diabetic retinopathy and diabetic macular oedema (DME). METHODS This was a single centre observational study conducted at a tertiary care hospital, where patients with type 2 diabetes of more than five years duration were enrolled. A comprehensive ophthalmic evaluation was performed on all study subjects. Detailed fundoscopy was done after obtaining the best possible mydriasis with 1 % tropicamide and 5 % phenylephrine eye drops using direct ophthalmoscopy, indirect ophthalmoscopy with + 20 D lens and stereoscopic slit lamp biomicroscopy of the disc and macula using + 78 D Volk lens. Fundus photographs were taken in patients with any grade of diabetic retinopathy by Topcon fundus camera. DR and DME were diagnosed and classified according to the Early Treatment Diabetic Retinopathy Study (ETDRS) grading system. Fasting blood sugar (FBS), fasting lipid profile and glycated haemoglobin (HbA1c) was assessed for each patient. RESULTS A total of two hundred and twelve participants was enrolled. Mean age of the study group was 63.93 ± 9.52 and the mean duration of diabetes was 13.54 ± 6.07. DR was present in 164 (78.1 %) of whom 71 (43.3 %) had mild non proliferative diabetic retinopathy (NPDR), 42 (25.6 %) had moderate NPDR, 31 (18.9 %) had severe NPDR, and 20 (12.2 %) had proliferative diabetic retinopathy (PDR). Of those with DR, 59 (36 %) had DME. Duration of diabetes (14.62 ± 6.18 vs 9.72 ± 3.68 years, P < 0.001), higher fasting blood glucose (176.79 ± 59.13 vs 138.46 ± 49.44 mg / dL, P < 0.001), higher HbA1c (8.21 ± 1.38 vs. 7.48 ± 1.25 %, P = 0.002), higher total cholesterol (215.04 ± 49.78 vs 184.37 ± 30.84 mg / dL, P < 0.001), higher triglyceride levels (155.23 ± 59.06 vs 125.13 ± 37.3 mg / dL, P = 0.001) and higher low density lipoprotein (LDL) cholesterol levels (139.28 ± 37.38 vs 120.85 ± 22.75 mg / dL, P = 0.002) were significantly associated with the severity of DR. Higher total cholesterol, higher triglyceride levels and higher LDL cholesterol levels were also associated with DME. CONCLUSIONS There is a significant association of abnormal serum lipid levels and hyperglycaemia with the presence and severity of DR and presence of DME. Early identification and intervention to control these modifiable risk factors, hyperglycaemia and dyslipidaemia may delay the development and progression of DR in diabetic patients. These observations also support the current management strategies for diabetes, which include control of dyslipidaemia in addition to hyperglycaemia.

Вопросы своевременной диагностики дефицита лизосомной кислой липазы у детей и молодых взрослых с нарушениями липидного профиля. Мнение экспертов

Lysosomal acid lipase deficiency (LAL-D) is a monogenic progressive life-threatening condition characterized by abnormal lipid profiles in most patients of all ages. Timely diagnosis and early pathogenetically-oriented treatment (available in Russia) are crucial for children and young adults since abnormal serum levels of lipids are associated with the onset and severity of atherosclerosis in adolescence, young and middle age. The prognosis of LAL-D without pathogenetically oriented treatment is poor. Data on cholesteryl ester storage disease (a variant of LAL-D in children and adults), early atherosclerosis, coronary heart disease, aortic calcification, etc., are available. However, early diagnosis of LAL-D is difficult due to long-term latent course and nonspecific clinical signs. In December 2020, a panel of leading Russian experts in the diagnosis and treatment of orphan diseases and lipidologists was held in Moscow. This panel developed an algorithm to optimize the early diagnosis of dyslipidemias in children and young adults and identify patients with LAL-D in a total population of patients with lipid profile abnormalities. KEYWORDS: lysosomal acid lipase deficiency, lipid profile, atherosclerosis, lipid center. FOR CITATION: Ezhov M.V., Zakharova E.Yu., Avramenko A.A. et al.

Protective Effect of Jiang Tang Xiao Ke Granules against Skeletal Muscle IR via Activation of the AMPK/SIRT1/PGC-1α Signaling Pathway.

The Jiang Tang Xiao Ke (JTXK) granule is a classic Chinese herbal formula that has been put into clinical use in the treatment of type 2 diabetes mellitus for decades. However, whether its ability to ameliorate skeletal muscle insulin resistance (IR) is through modulation of the AMPK/SIRT1/PGC-1α signaling pathway remains unknown. Therefore, we aimed to investigate the effects of JTXK granules on IR in skeletal muscle of high-fat diet-induced diabetic mice and C2C12 cells and analyze the underlying mechanisms. In the present study, we showed that JTXK granules attenuated body weight gain, reduced body fat mass, improved body lean mass, and enhanced muscle performance of diabetic mice. JTXK granules also improved glucose metabolism and skeletal muscle insulin sensitivity and partially reversed abnormal serum lipid levels, which might be related to the regulation of the AMPK/SIRT1/PGC-1α pathway, both in skeletal muscle tissue of diabetic mice and in C2C12 cells. Furthermore, drug-containing serum of JTXK granules was capable of enhancing glucose uptake and mitochondrial respiration in C2C12 cells, and AMPKα was proven to be closely involved in this process. Taken together, these results suggest that the JTXK granule ameliorates skeletal muscle IR through activation of the AMPK/SIRT1/PGC-1α signaling pathway, which offers a novel perspective of this formula to combat IR-related metabolic diseases.

A study of electrocardiographic and lipid changes in patients with type II diabetes mellitus

Background: Diabetes mellitus (DM) is a group of metabolic disorders characterized by hyperglycemia resulting from variable interactions of hereditary and environmental factors due to defects in insulin secretion, insulin action, or both. People with type II DM have a 2-fold higher risk of developing cardiovascular disease (CVD) compared to the general population. Resting electrocardiogram (ECG) abnormalities are associated with excess risk of diabetes-induced CVD morbidity and mortality. Around 50% of all diabetics, whether type I or II, are known/found to have dyslipidemia. The frequency of developing dyslipidemia has been found to be higher in people with poorly controlled type II DM. Abnormal blood lipid levels resulting from altered lipid metabolism are considered to be major contributing factors in macrovascular complications, coronary artery disease, etc., that are known to be associated with diabetes. Aims and Objectives: This study aims to observe and analyze whether dyslipidemia and ECG abnormalities are present concurrently in patients suffering from type II DM, and whether any correlation exists between lipid profile and ECG changes in these patients. Materials and Methods: A cross-sectional study was carried out in a tertiary care hospital affiliated to a medical college situated in East Godavari district of Andhra Pradesh over a period of 1⅟2 years. One hundred known diabetic patients (as determined by the inclusion criteria) were selected for the study. Blood samples were analyzed for glucose (fasting and postprandial), glycosylated hemoglobin, and lipid profile. Resting 12 leads ECG was taken at the outpatient department for all patients. Results: Statistical analysis was carried out using SPSS software (version 23.00) and results were statistically analyzed and correlated. The values of blood cholesterol, low-density lipoproteins, and triglycerides were found to be significantly elevated with a high degree of correlation. High-density lipoproteins values were found to be low in these patients. ECG showed significant decrease in the amplitude of P waves, and duration of QRS complex and QT interval was also increased in these patients. Conclusion: Dyslipidemia and resting ECG abnormalities are common in people with type II DM including those without a history of CVD. The resting ECG assists in cardiac screening of asymptomatic type II diabetic individuals and helps to detect cardiac abnormalities. Regular monitoring of glycemic and lipid profiles and maintaining a strict glycemic control helps in averting complications associated with diabetes and cardiovascular diseases.

Glucagon-Like Peptide-1 Receptor Agonist Utilization in Type 2 Diabetes in Japan: A Retrospective Database Analysis (JDDM 57).

IntroductionThere are limited real-world data on the prescribing of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) for patients with type 2 diabetes mellitus (T2DM).MethodsThis was a retrospective analysis of the CoDiC® database of the Japan Diabetes Clinical Data Management Study Group (JDDM). Demographic and clinical characteristics, concomitant treatment patterns, and GLP-1 RA treatment persistence or modification in patients with T2DM initiating GLP-1 RA therapy were evaluated.ResultsThe analysis included 932 eligible patients with T2DM who had their first GLP-1 RA prescription (index date) between September 2016 and July 2018. Mean age was 63.8 years and 56.0% were male. Most patients had an index GLP-1 RA of dulaglutide (65.7%) or liraglutide (29.1%). Common comorbidities were obesity (58.7%), hypertension (54.7%), dyslipidemia (52.0%), retinopathy (11.3%), and nephropathy (10.2%). Mean hemoglobin A1c (HbA1c) levels decreased from 8.3 to 7.8% over 6 months after GLP-1 RA initiation, and the proportion of patients achieving HbA1c < 7.0% increased from 14.4% at index date to 22.9% at 6 months. Reductions occurred in mean body weight, body mass index, triglycerides, total cholesterol, low-density lipoprotein cholesterol, and adjusted urinary albumin over 6 months. Antidiabetic medication use decreased after GLP-1 RA initiation, whereas non-antidiabetic medication prescribing showed little change. Index GLP-1 RA persistence rates were 80.5%, 66.2%, and 51.6% at 6, 12, and 18 months post-index, respectively, with a median persistence until discontinuation or switch of 600 days. Persistence rates at 6, 12, and 18 months post-index, respectively, were 81.9%, 70.7%, and 65.4% for dulaglutide and 79.7%, 60.0%, and 30.4% for liraglutide.ConclusionThe study shows real-world benefits of GLP-1 RA therapy for T2DM, including improvements in HbA1c, body weight, and blood lipid profile, and supports the high rates of long-term persistence previously reported with dulaglutide, the GLP-1 RA most commonly prescribed for T2DM in Japanese clinical practice.Supplementary InformationThe online version of this article (10.1007/s13300-020-00977-w) contains supplementary material, which is available to authorized users.

Dyslipidaemia among Irish children - preliminary findings from the Celtic ranges project

Background and Aims: The aim of the study is to determine the prevalence of dyslipidaemia in Irish children aged ≤ 12 years. Dyslipidaemia often begins in childhood and adolescence. Identifying children with dyslipidaemia and effectively improving their lipid profile may reduce their risk of accelerated atherosclerosis and premature CVD. We used values recommended by the NCEP Expert Panel on Cholesterol Levels in Children to define abnormal lipid levels.

Dyslipidemia in blood pressure control among adult hypertensive patients in Kiambu County Hospital Kenya

Introduction: Hypertension is one of the most common non-communicable diseases with about 40% global prevalence in adults and 46% in Africa. Dyslipidemia, among other factors may lead to poor blood pressure control in hypertensive patients. Dyslipidemia occurs when someone has abnormal levels of lipids in their blood However, the role of dyslipidemia in predicting hypertension has not received adequate attention.&#x0D; Objectives: This study aims to determine the relationship between dyslipidemia and blood pressure control among hypertensive patients in Kiambu County Hospital Kenya.&#x0D; Methods: This was a cross-sectional analytical study assessing independent association between blood pressure control and dyslipidemia in a cohort of 251 hypertensive patients in a hospital set up. Multiple logistic regression model was applied to determine factors associated with poor blood pressure control.&#x0D; Results: In total, 251 hypertensive patients, mean age 55.7 years, females-majority (80.9%) were considered in the study. The mean systolic blood pressure was 145.1±22.4mmHg and 87.4±13.0mmHg for diastolic blood pressure. Blood pressure was poorly controlled in 56.6% of the patients. High LDL levels was diagnosed in 82.1% of the patients, 23.1% low HDL levels, 31.9% high triglycerides and 59.8% high total cholesterol levels. Patients with poorly controlled hypertension (68.7%) recorded significantly higher mean total cholesterol (221.4 mg/dl) compared to193.4 mg/dl in the wellcontrolled group (mean 193.4 mg/dl), p0.05).&#x0D; Conclusion: Dyslipidemia was recorded in 68% of adult hypertensive patients and was significantly associated with development of of inadequate blood pressure control. Low density lipids ( LDL) was significantly higher in the poorly controlled group where 68.7% of the patients with high level of total cholesterol had poorly controlled blood pressure. Lifestyle modification, routine lipid profile testing among hypertensive patients, early treatment on high lipid level patients, change of lifestyle and use of statin were recommended for dyslipidemia treatment.

Prevalence and Associated Factors of Dyslipidemia Among Adults with Type 2 Diabetes Mellitus in Saudi Arabia.

IntroductionDyslipidemia is a key clinical abnormality among diabetes mellitus (DM) patients, which heightens their risk of cardiovascular events. Data on the serum lipid profile of type 2 DM (T2DM) patients in Saudi Arabia are scarce. This study therefore aimed to establish dyslipidemia prevalence in a sample of adult T2DM patients in Saudi Arabia and to investigate its associated factors.Patients and MethodsA cross-sectional survey was applied to 400 adult T2DM outpatients in attendance at a diabetic center clinic in Tabuk, Saudi Arabia between September 2017 and December 2018 using convenience sampling. Structured questionnaires gathered data relating to the potential risk factors for dyslipidemia. Data on fasting blood glucose (FBG), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) levels were collected from all participants along with their height and weight measurements. Multivariate logistic regression analysis was then used to evaluate the associated risk factors for dyslipidemia.ResultsOf the sampled outpatients, 47.8% had high TC levels, 39.0% had high LDL-C, 35.5% had low HDL-C, 42.8% had high TG levels, and 66.5% had a minimum of one abnormal lipid level (dyslipidemia). The risk factors associated with dyslipidemia were an age of >40 years (adjusted odds ratio [AOR] = 1.96, 95% CI 1.19–3.22), irregular exercise (AOR = 2.90, 95% CI 1.21–6.92), a family history of T2DM (AOR = 3.72, 95% CI 2.22–6.23), having had T2DM for >7 years (AOR = 2.42, 95% CI 1.46–3.99), and overweight (AOR = 2.61, 95% CI 1.49–4.58) or obesity (AOR = 2.50, 95% CI 1.24–5.05).ConclusionDyslipidemia prevalence was found to be high among T2DM patients. Therefore, a compressive mechanism is needed which can screen, treat, and inform them about dyslipidemia and its risk factors, especially modifiable ones such as obesity and exercise.

Night sleep duration and risk of each lipid profile abnormality in a Chinese population: a prospective cohort study

BackgroundTo explore the associations between sleep duration and abnormalities in serum lipid levels in a Chinese population.MethodsA prospective study was conducted with 34,260 participants from the general Chinese population. Sleep duration was categorized as ≤5, 6, 7, 8 or ≥ 9 h. Each lipid profile abnormality was defined according to the Chinese Guidelines for the Prevention and Treatment of Dyslipidemia in Adults (2016). The Cox proportional hazards model was used to assess the association between sleep duration and dyslipidemia.ResultsCompared with a 7 h sleep duration, long sleep duration (≥9 h) was significantly associated with low high-density lipoprotein cholesterol (HDL-C) levels (hazard ratio (HR): 1.24; 95% CI: 1.12–1.38). In subgroup analyses, the positive association between long sleep duration and low HDL-C level in men and in the different age groups was more pronounced than the association in women. No significant interactions were observed in the association between sleep duration and each abnormal serum lipid level by sex/age in the study population (P-interaction> 0.05).ConclusionsThese findings suggest that long sleep duration is associated with low HDL-C level among the Kailuan community population.

A study of variation in serum lipid levels in patients with Plasmodium vivax malaria

Background: Malaria is a common protozoal infection. Plasmodium vivax malaria is the most common species distributed worldwide and in India. The vivax malarial infection is associated with various haematological and biochemical abnormalities, anaemia and thrombocytopenia among the frequently identified abnormal parameters. However vivax malaria is also associated with abnormal lipid levels including low cholesterol levels and normal to high serum triglyceride levels.Methods: This study is a cross-sectional observational study including 100 inpatients admitted to Medical College Hospital over a period of 18 months diagnosed with Plasmodium vivax malaria. The patients were selected based on inclusion and exclusion criteria. The relevant data was collected and analysed.Results: Vivax malaria infection was found to be more common among males (80%) and during third decade of life (51%). HDL Cholesterol was decreased in all cases, LDL Cholesterol and Total Cholesterol was also decreased in nearly all patients with only 1% cases having values above normal range. Serum Triglycerides was elevated more than 150 mg/dl in 69% cases with 25% cases having values above 200mg/dl. The hypocholestrolemia and hypertriglyceridemia were directly proportional to the thrombocytopenia, hyperbilirubinemia, elevated serum creatinine levels and parasite load.Conclusions: This study demonstrates the presence of altered serum lipid levels in the form of hypocholesterolemia and hypertriglyceridemia in cases of Plasmodium vivax malaria mono infection. This study also shows that the above lipid alterations were found to be deranged to greater extent in clinically, haematologically and biochemically severe form of infections.

Chinese herbal medicine mixture 919 syrup alleviates nonalcoholic fatty liver disease in rats by inhibiting the NF-κB pathway

BackgroundIn many countries, nonalcoholic fatty liver disease (NAFLD) has risen to be the leading cause of liver disease, seriously threatening public health, while effective medical treatments are currently limited. 919 syrup (919 T J) is a Chinese herbal medicine, and both clinical and experimental studies have revealed that it can improve liver function. ObjectiveTo study whether 919 T J shows a protective effect in a NAFLD rat model and explore its underlying mechanism, with a focus on the NF-κB pathway. MethodsRats were randomly divided into three groups, including a control group, NAFLD group, and 919 T J group (n = 10 each). The control group received a standard diet, and the other two groups were fed a high-fat diet to establish the NAFLD model. From week 10, rats in the 919 T J group were intragastrically administered 919 T J for 4 weeks, and the NAFLD group was administered the same amount of saline. All rats were anesthetized at the beginning of week 14 to collect blood and liver specimens. Serum lipid levels, serum biochemical markers of liver function, and the gene expression levels of IL-1β, TNF-α, CXCL6, CXCR1, SREBP-1c, PPARγ, and NF-κB in the liver were measured. Oil Red O and hematoxylin and eosin staining of the liver was performed to observe pathological changes in the liver. ResultsSignificant abnormalities in serum lipid levels and serum biochemical markers of liver function were found in the NAFLD group relative to those in the control group. In addition, serious abnormalities were noted in the expression levels of liver inflammatory factors and lipid metabolism-related genes. Treatment of NAFLD rats with 919 T J reduced body weight and food intake and ameliorated the abnormal blood lipid levels and liver function markers. By regulating the NF-κB pathway, 919 T J downregulated the NF-κB-related proinflammatory signals, ameliorating the expression of inflammatory (IL-1β, TNF-α, CXCL6, and CXCR1) and lipid metabolism-related (SREBP-1c) factors in the liver and improving the NAFLD-induced pathological changes in the liver. Conclusion919 T J reduces the liver injury, steatosis, and inflammation caused by NAFLD, thus reversing the disease process.

High prevalence of plasma lipid abnormalities in human and canine Duchenne and Becker muscular dystrophies depicts a new type of primary genetic dyslipidemia

Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are allelic X-linked recessive muscle diseases caused by mutations in the DMD gene, with DMD being the more severe form. We have recently shown that increased plasma low-density lipoprotein-associated cholesterol causes severe muscle wasting in the mdx mouse, a mild DMD model, which suggested that plasma lipids may play a critical role in DMD. We have also observed that loss of dystrophin in mice causes unexpected elevations in plasma lipoprotein levels. The objectives of the study were to determine whether patients with DMD and BMD also present with clinically relevant plasma lipoprotein abnormalities and to mitigate the presence of confounders (medications and lifestyle) by analyzing the plasma from patients with DMD/BMD and unmedicated dogs with DMD, the most relevant model of DMD. Levels of low-density lipoprotein-associated cholesterol, high-density lipoprotein cholesterol, and triglycerides were analyzed in patients with DMD and BMD and female carriers. Samples from unmedicated, ambulatory dogs with DMD, unaffected carriers, and normal controls were also analyzed. We report that 97% and 64% of all pediatric patients with DMD (33 of 36) and BMD (6 of 11) are dyslipidemic, along with an unusually high incidence in adult patients with BMD. All dogs with DMD showed plasma lipid abnormalities that progressively worsened with age. Most strikingly, unaffected carrier dogs also showed plasma lipid abnormalities similar to affected dogs with DMD. Dyslipidemia is likely not secondary to liver damage as unaffected carriers showed no plasma aminotransferase elevation. The high incidence of plasma lipid abnormalities in dystrophin-deficient plasma may depict a new type of genetic dyslipidemia. Abnormal lipid levels in dystrophinopathic samples in the absence of muscle damage suggest a primary state of dyslipidemia. Whether dyslipidemia plays a causal role in patients with DMD warrants further investigation, which could lead to new diagnostic and therapeutic options.

The effects of exercise training on lipid metabolism and coronary heart disease.

Blood lipoproteins are formed by various amounts of cholesterol (C), triglycerides (TGs), phospholipids, and apolipoproteins (Apos). ApoA1 is the major structural protein of high-density lipoprotein (HDL), accounting for ~70% of HDL protein, and mediates many of the antiatherogenic functions of HDL. Conversely, ApoB is the predominant low-density lipoprotein (LDL) Apo and is an indicator of circulating LDL, associated with higher coronary heart disease (CHD) risk. Thus, the ratio of ApoB to ApoA1 (ApoB/ApoA1) is used as a surrogate marker of the risk of CHD related to lipoproteins. Elevated or abnormal levels of lipids and/or lipoproteins in the blood are a significant CHD risk factor, and several studies support the idea that aerobic exercise decreases CHD risk by partially lowering serum TG and LDL-cholesterol (LDL-C) levels and increasing HDL-C levels. Exercise also exerts an effect on HDL-C maturation and composition and on reverse C transport from peripheral cells to the liver to favor its catabolism and excretion. This process prevents atherosclerosis, and several studies showed that exercise training increases heart lipid metabolism and protects against cardiovascular disease. In these and other ways, it more and more appears that regular exercise, nutrition, and strategies to modulate lipid profile should be viewed as an integrated whole. The purpose of this review is to assess the effects of endurance training on the nontraditional lipid biomarkers, including ApoB, ApoA1, and ApoB/ApoA1, in CHD risk.

The Trp64Arg polymorphism in \u03b23 adrenergic receptor (ADRB3) gene is associated with adipokines and plasma lipids: a systematic review, meta-analysis, and meta-regression

BackgroundRecently, some studies claim that adipokines may modulate plasma lipids. More interestingly, the ADRB3 Trp64Arg polymorphism may regulate adipokines and play an essential role in lipids metabolism. This study aims to clarify the associations of ADRB3 Trp64Arg polymorphism with plasma adipokines and lipid levels.MethodsTwenty-two studies (5527 subjects) and 121 studies (54,059 subjects) were respectively identified for the association analyses of adipokines and lipids. Standardized mean difference (SMD) and 95% confidence interval (CI) were used to estimate the strength of the Trp64Arg variant in adipokines and plasma lipids. All results were recalculated after eliminating the studies with heterogeneity.ResultsThe carriers of the C allele (Arg at 64th position was encoded by the C allele) had higher levels of leptin and lower levels of adiponectin than the non-carriers. The carriers of the C allele had higher levels of triglycerides (TG), total cholesterol (TC), and lower levels of high-density lipoprotein cholesterol (HDL-C) than the non-carriers. Subgroup analysis certified an ethnicity (Asians), disease status (obesity), and gender (females) specific association. Sensitivity analysis indicated that the analysis results were robust and stable. Meta-regression indicated that obesity was related to adiponectin.ConclusionsThe C allele carriers of Trp64Arg polymorphism had a slight but significant influence on lipid levels, and the remarkable effects specific existed in obese Asian women. The associations of Trp64Arg polymorphism with dyslipidemia may partly be mediated by the effect of this polymorphism on adipokines. The association of Trp64Arg polymorphism with obesity may partly be mediated by the effect of this polymorphism on adipokines. The C allele carriers had abnormal levels of adipokines and lipids, and it indicated that the Trp64Arg polymorphism might represent a genetic risk factor for coronary artery disease (CAD).

Association between Three Low-Carbohydrate Diet Scores and Lipid Metabolism among Chinese Adults.

This study investigated the blood lipid levels of 5921 Chinese adults aged >18 years using data from the China Health and Nutrition Survey 2009. Diet information was collected through 3 day, 24 h recalls by trained professionals. The low-carbohydrate diet (LCD) score was determined according to the percentage of energy obtained from carbohydrate, protein, and fat consumption. Dyslipidemia was defined when one or more of the following abnormal lipid levels were observed: high cholesterol levels, high triglyceride levels, and low high-density lipoprotein cholesterol levels. Multivariate adjusted odds ratios (ORs) and their 95% confidence intervals (95% CIs) were calculated using logistic regression models. After adjusting the confounding variables, in males, the OR of hypercholesterolemia was 1.87 (95% CI, 1.23–2.85; p for trend = 0.0017) and the OR of hypertriglyceridemia was 1.47 (95% CI, 1.04–2.06; p for trend = 0.0336), on comparing the highest and lowest quartiles of the LCD score. The animal-based LCD score showed a similar trend. The OR of hypercholesterolemia was 2.15 (95% CI, 1.41–3.29; p for trend = 0.0006) and the OR of hypertriglyceridemia was 1.51 (95% CI, 1.09–2.10; p for trend = 0.0156). However, there was no significant difference between plant-based LCD scores and dyslipidemia. In females, lipid profiles did not differ much among the quartiles of LCD scores—only the animal-based LCD score was statistically significant with hypercholesterolemia. The OR of hypercholesterolemia was 1.64 (95% CI, 1.06–2.55), on comparing the highest and lowest quartiles of the LCD score. In conclusion, a higher LCD score, indicating lower carbohydrate intake and higher fat intake, especially animal-based fat, was significantly associated with higher odds of hypercholesterolemia and hypertriglyceridemia in Chinese males. Future studies investigating the potential mechanisms by which macronutrient types and sex hormones affect lipid metabolism are required.

The feasibility of non-communicable disease (NCD) risk-factor estimation among forest staff at Sahyadri Tiger Reserve in Central India

ABSTRACT An increasing prevalence of non-communicable disease (NCD) risk factors in countries like India could pose a threat to the health and field capacities of forest staff. However, there is a lack of data globally about their NCD risks. Using data from preventive health checks conducted for forest staff at Sahyadri Tiger Reserve, in Maharashtra, Central India, this study assessed the feasibility of screening for NCD risk factors such as elevated glycated hemoglobin (HbA1C), abnormal lipid levels, use of tobacco and alcohol, high body mass index, high waist circumference, and elevated blood pressure. Follow-up surveys were conducted six months after preventive health interventions to collect details of health service utilization as well as feedback for the preventive health interventions. While reporting a high prevalence of NCD risk factors among forest staff – which could predispose them to cardiovascular disease – this study demonstrates that implementing workplace-based NCD screening interventions is feasible, effective, acceptable, and beneficial to forest staff. Key policy insights Non-communicable diseases (NCDs) and associated risk factors may play an important role in the sustainability of conservation efforts. NCDs should be integrated as a key component of the One Health paradigm. Workplace-based interventions for prevention and screening of NCDs could provide a feasible and effective method to mitigate health inequalities faced by the conservation workforce. Collaborative efforts to address the health needs of conservation staff working in remote rural regions could help achieve mutually beneficial outcomes for human health and conservation.

Abstract P555: Plasma Lipids And The Risk For Stroke In The Reasons For Geographic And Racial Differences In Stroke Study (regards).

Introduction: Whether plasma lipid levels are associated with stroke risk remains controversial, with even less data for American blacks versus whites. Hypothesis: We hypothesized that abnormal lipid levels are not associated with stroke incidence in either blacks or whites. Methods: The REasons for Geographic And Racial Differences in Stroke (REGARDS) study recruited 30,283 black and white individuals aged 45+ from the contiguous U.S. between 2003 to 2007, participants with a history of stroke at baseline were excluded. Participants were followed until 2018 for stroke events following the WHO definition and confirmed by review of medical records. The association of lipid measures with stroke were assessed using Cox regression models adjusted for traditional CVD risk factors and an age-x-race interaction term. Results: With 27,714 participants (mean age 64.85± 9.43, 59.5% white and 55.4% female), over a median of 11 years of follow up, 1,415 stroke events occurred, of which 599 among blacks. After adjusting for traditional stroke risk factors, there were modest associations between higher total cholesterol and higher LDL, but not higher triglycerides, with stroke risk. There was no evidence of a race interaction. Overall, HDL levels were not associated with stroke risk. However, when stratified by race, whites had a reduced risk of stroke with higher HDL-C, whereas no association was seen among blacks (p-interaction 0.09). Conclusion: In REGARDs, there was a modest association of cholesterol measures with stroke risk. The association for HDL with stroke may be influenced by race, with a less strong association among blacks than among whites.
