Association Between Nontraditional Lipid Profiles and the Risk of Type 2 Diabetes Mellitus in Chinese Adults With Hypertension: Findings From the China Hypertension Registry Study.

The relationship between nontraditional lipid profiles and type 2 diabetes mellitus (T2DM) remains ambiguous within the hypertension population. The objective of this study is to examine the association between nontraditional lipid profiles and T2DM in Chinese adults with hypertension. The current investigation encompassed 13728 participants with hypertension from the China Hypertension Registry Study. Logistic regression analysis and smooth curve fitting were employed to evaluate the association between nontraditional lipid profiles and T2DM. The prevalence of T2DM was found to be 17.8%. In the fully adjusted model, atherogenic index of plasma (AIP) exhibited the highest odds ratios (ORs) for T2DM (OR: 2.71, 95% confidence interval [CI]: 2.26-3.26). Conversely, the fully adjusted ORs (95% CI) for total cholesterol (TC)/high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C)/HDL-C, and non-high-density lipoprotein cholesterol (Non-HDL-C) were 1.33 (1.25-1.41), 1.40 (1.29-1.51), and 1.41 (1.34-1.49), respectively. Additionally, the study demonstrated that AIP had a superior ability to identify T2DM. Subgroup analyses indicated that the relationship between AIP and Non-HDL-C with T2DM was more significant in the lighter weight population. In addition, the association of TC/HDL-C with LDL-C/HDL-C with T2DM was stronger in the lower homocysteine level population. Among the southern Chinese population with hypertension, all nontraditional lipid indices positively correlated with the risk of T2DM. Among these lipid indices, AIP exhibited superior discriminatory power in identifying T2DM compared to TC/HDL-C, LDL-C/HDL-C. Trial Registration: ChiCTR1800017274.

Exploring the Correlation Between Salt Tolerance and Seed Nutritional Value of Different Quinoa Genotypes Grown Under Saharan Climatic Conditions

Quinoa is an annual pseudocereal highly adapted to extreme environments and has become, at this point in time, an extremely popular food due to its exceptional and high nutritional quality. This study aims to investigate the association of quinoa salt tolerance at an early developmental stage with its grain nutritional value under the effect of severe climatic hurdles. The current findings revealed a significant variability between genotypes in salt response attributes at the first development stage, where genotypes Amarilla Sacaca (thereafter, A. Sacaca) and QQ57 exhibited high salt tolerance thresholds with a low salt sensitivity index (SI), and a high capacity for Na+ sequestration into vacuoles. A significant positive association was detected between salt tolerance degree and yield parameters, saponins (SAPs), and minerals contents, where genotype A. Sacaca exhibited the highest SAP content with 3.84 mg.g−1 and the highest amounts of K, Ca, P, and Fe. The analysis of fatty acid composition demonstrated a high significant negative correlation between crude fat content and salt SI, and between yield parameters. Despite its low harvest index (HI) and low seed oil content, the salt-tolerant genotype A. Sacaca showed a high nutritional quality for seed oil according to its lowest ω6/ω3 ratio (5.6/1) and lowest level of atherogenicity index (AI). The genotype 115R, defined as the most sensitive to salt stress, exhibited a high seed oil quality due to its low lipid peroxidation susceptibility as reflected by its oxidative susceptibility and peroxidizability indexes. The significance of this study includes the identification of valuable quinoa genotypes showing high efficiency in growth and yield under severe stress accompanied by a high nutritional value satisfying the market requirements for healthy, nutritious, and safe food products.

Different lines of camelina (Camelina sativa (L.) Crantz) in broiler quails’ diets: effects on meat physicochemical traits and sensory profile

The present study investigated the effect of Camelina sativa cake dietary inclusion on quail meat fatty acids (FA), amino acids (AA), and sensory characteristics. To this, 480 broiler quails were allocated to four dietary treatments (12 replicated cages/treatment): a control diet (Control) and three diets with 15% camelina cake, containing a commercial cultivar (Calena) and two improved lines (Pearl: low linoleic acid; Alan: low glucosinolates). After slaughter, breast meat FA and AA profiles and contents were analysed, alongside a sensory evaluation by trained panellists. The dietary inclusion modified breast meat FA profile and contents (p < .001), notably increasing α-linolenic acid (C18:3 n-3), which improved overall n-3 PUFA and reduced the n-6/n-3 ratio to recommended levels. Health indices improved in a line-dependent manner: atherogenicity lowered in Alan compared to Control and Calena (p < .01), while thrombogenicity reduced in all camelina treatments than the Control (p < .001). Camelina-fed groups showed an AA profile in line with the Control one, and Pearl displayed a higher essential AA content compared to Alan (p < .05). Sensory results indicated no substantial changes in meat attributes across treatments, except for tenderness and animal fat flavour: the first lowered in Alan meat compared to the Control (p < .05), while the latter was higher in the Control than in Alan and Calena groups (p < .01). In conclusion, the 15% dietary inclusion of different camelina cakes in quail diets positively influenced meat FA, enhancing product healthiness without negatively impacting its nutritional quality and sensory attributes. Findings indicated that camelina cake is an effective feedstuff to improve quail meat quality. HIGHLIGHTS Once fed to quails, all tested camelina cakes increased meat n-3 PUFA and reduced the n-6/n-3 by about 5 and 7 times, respectively. Meat atherogenicity and thrombogenicity indices of camelina-fed quails improved, indicating enhanced product healthiness. Camelina inclusion did not alter quail meat sensory attributes compared to the control group.

Efficacy of levothyroxine monotherapy in achieving clinical euthyroidism and its impact on weight loss in women with hypothyroidism and obesity.

In light of research indicating that normal TSH levels do not necessarily reflect clinical euthyroidism in hypothyroid patients, and given the patient dissatisfaction with levothyroxine (LT4) monotherapy, we evaluate the response to weight loss treatment in patients with obesity and primary hypothyroidism who are euthyroid under LT4 therapy, with a focus on weight and metabolic parameters. The retrospective study included 138 subjects with obesity (BMI ≥ 30kg/m2), 69 women with hypothyroidism on levothyroxine, and 69 age- and BMI-matched women without thyroid disease. Secondary causes of obesity, medications that may affect thyroid functions and metabolic parameters, chronic and oncological disease, pregnancy, TSH outside the reference range, follow-up periods of less than one year, and bariatric surgery were the exclusion criteria. Patients' characteristics and metabolic responses to weight reduction treatment consisting of calorie restriction, moderate exercise, and metformin if needed were evaluated. TSH and fT4 levels were higher, and fT3 and T3/T4 ratios were lower all within the reference ranges in hypothyroid women. They were less insulin resistant. Both patient' groups experienced a significant decrease in body weight, BMI, and atherogenic index of plasma (AIP) during the follow-up (p = 0.001). Insulin resistance was not changed. The groups' body weight, BMI, HOMA-IR, and AIP changes were similar at the end of the study (p = 0.876, p = 0.850, p = 0.555, p = 0.293). The results suggest that achieving euthyroid status via levothyroxine monotherapy in hypothyroid women leads to weight loss responses comparable to those in women with normal thyroid. This supports the effectiveness of current hypothyroidism treatment strategies, emphasizing TSH level normalization, in achieving clinical euthyroidism concerning weight loss outcomes.

Estimated glucose disposal rate is correlated with increased depression: a population-based study.

Recent studies have identified a correlation between insulin resistance (IR) and depression. This study aims to explore the correlation between estimated glucose disposal rate (eGDR), a practical and noninvasive measure for assessing IR, and depression in the general population. In this population-based cross-sectional study, data from 28,444 adults aged 18 years old or older in the NHANES during the period from 1999 to 2018 were analyzed. The correlation between eGDR and depression was examined through multivariate logistic regression analyses, subgroup analyses, restricted cubic spline, and interaction tests. Furthermore, a mediation analysis was conducted to elucidate the role of the atherogenic index of plasma (AIP) in mediating the effect of eGDR on depression. Multivariate logistic regression analysis and restricted cubic splines analysis indicated that eGDR can exhibit a linearly correlation with depression (OR = 0.913; 95% CI: 0.875, 0.953). Subjects in eGDR6-8 and eGDR > 8 groups had a decrease risk of depression as 25.4% and 41.5% than those in the eGDR < 4 group. This negative correlation was more pronounced in those with obesity. Mediation analysis indicated that AIP mediated 9.6% of the correlation between eGDR and depression. eGDR was linear negatively correlated with depression, with AIP playing a mediating role. This study provides a novel perspective on the mechanism connecting IR to depression. Managing IR and monitoring AIP may contribute to alleviating depression.

Comparative Evaluation of Camelina Seed Oils Obtained by Cold-Pressing and Solvent Extraction

This study aimed to analyze the physicochemical properties and nutritional quality of oil extracted from the camelina seed genotypes NS Zlatka and NS Slatka, grown in Serbia, using both Soxhlet extraction with n-hexane and the cold-pressing technique. Extraction technique did not have an effect on oil yield. Camelina oils exhibited satisfactory physicochemical characteristics, which were influenced by the extraction methods. The oils were rich in polyunsaturated fatty acids, with α-linolenic acid being the most abundant. They were characterized by a balanced ω-6 to ω-3 ratio (0.5), low atherogenicity index and thrombogenicity index values, and a relatively high hypocholesterolemic/hypercholesterolemic ratio. Cold-pressed oils contained significantly higher amounts of α- and γ-tocopherols and showed greater oxidative stability at moderate temperatures, as confirmed by the Schaal oven test. Despite this, their oxidative stability decreased at elevated temperatures (Rancimat test) compared to solvent-extracted oils. Conversely, solvent-extracted oils had higher levels of β-carotene and showed superior resistance to high-temperature conditions. Due to its unique characteristics, nutritional properties, and health-promoting attributes, cold-pressed camelina oil presents significant potential for application in food, nutraceutical, feed, and cosmetic industries.

A U-shaped relationship between the atherogenic index of plasma and repeated target vessel revascularization in patients undergoing percutaneous coronary intervention: a retrospective study

BackgroundAtherogenic index of plasma (AIP) has been recognized as a novel and practical marker for the assessment of cardiometabolic risk, but the relevance of AIP as a prognostic biomarker in coronary artery disease (CAD) remains debated. This study investigated the association between AIP and major adverse cardiac and cerebrovascular events (MACCEs) in CAD patients receiving percutaneous coronary intervention (PCI) with drug-eluting stents (DES).MethodsA total of 2,250 patients undergoing PCI with DES were included in this retrospective cohort study. The primary endpoint was MACCEs, encompassing acute myocardial infarction, repeat target vessel revascularization (TVR), stroke, and all-cause mortality. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Restricted cubic splines were applied to explore the dose–response associations. And subgroup analysis was conducted to evaluate potential relationship between AIP and MACCEs across different subgroups.ResultsDuring a medium follow-up of 29.8 (25.6–34.0) months, 106 (4.7%) patients experienced TVR. After adjusting for confounders, AIP (per 1 SD increase) was positively associated with TVR (odds ratio [OR] = 1.26, 95% confidence interval [CI] = 1.01–1.58, P = 0.042). In females, there was a significant association (OR = 2.33, 95% CI = 1.40–3.98, P = 0.002), but no significant association was observed in males. There was an interaction between AIP and gender (P = 0.017). Restricted cubic spline analysis depicted a U-shaped relationship between AIP and TVR (Pnonlinear = 0.016), with an elevated risk evident from an AIP of 0.20.ConclusionAIP showed a U-shaped relationship with TVR in PCI patients with DES, particularly pronounced among females. We suggested that the AIP should be used as a plasma marker of key interest for preventing TVR after DES implantation in patients with CAD.

The triglyceride-glucose index as an indicator of latent atherogenicity of the plasma lipid profile in healthy men with normolipidaemia

ABSTRACT Objectives The triglyceride-glucose (TyG) index is a novel diagnostic marker for various metabolic and cardiovascular diseases. However, little is known about the association of the TyG index with plasma atherogenicity, especially with its latent forms. The aim of this study was to assess the potential of the use of the TyG index as a marker of atherogenic risk. Methods A total of 202 men with normolipidaemia, aged 20–60 years, were enrolled in this study. Fasting biochemical parameters were measured. The TyG index was calculated as ln[triglyceride(mg/dL)×glucose(mg/dL)]/2. The diagnostic ability of the TyG index for detecting atherogenic risk was tested by receiver operating characteristic (ROC) curve analysis. Results A substantial portion of normolipidaemic men had deviations from the reference values for the indices calculated using apolipoproteins. Unfavorable values for the apolipoprotein (apo) B/apoA-I ratio, low-density lipoprotein cholesterol/apoB (LDL-C/apoB) ratio, and the atherogenic index (ATH index) were observed in 32.7%, 31.7%, and 14.4% of men, respectively. The results of ROC curve analysis showed that the TyG index had good diagnostic ability for identifying unfavorable apolipoprotein indices in normolipidaemic men. Conclusions Thus, the TyG index can be a valuable additional marker for assessing latent atherogenic risk; it can provide useful information for the diagnosis and treatment of early atherosclerosis.

Relationship of the Degree of Sarcopenia with the Severity of Nonalcoholic Fatty Liver Disease and Cardiometabolic Risk in Adolescents

The association between nonalcoholic fatty liver disease (NAFLD) and sarcopenia has been suggested. We investigated sarcopenia’s impact on NAFLD severity and its relationship with cardiometabolic risk in adolescents. We conducted a retrospective study on 122 patients aged 13–18 years and diagnosed with both NAFLD and sarcopenia by laboratory tests, abdominal ultrasound (US), and multifrequency bioelectrical impedance analysis. Sarcopenia was stratified into tertiles based on the skeletal muscle-to-fat ratio (MFR), NAFLD severity was established by the US, and cardiometabolic risk was assessed by the triglyceride–glucose (TyG) index and the atherogenic index of plasma (AIP). Compared with the other patients, those in the lower MFR tertiles exhibited a greater severity of NAFLD (p &lt; 0.001) and significantly higher TyG index and AIP. The independent effect of MFR was observed to have a negative correlation with the severity of NAFLD (p &lt; 0.001). Based on the aforementioned results, the degree of sarcopenia can be considered as one of the risk factors of severe NAFLD and might be an indicator of cardiometabolic risk in adolescents. Weight training to reach the amount of muscle mass could be included in the treatment strategies to improve or prevent NAFLD in adolescents with sarcopenia.

Association between cardiorenal syndrome and depressive symptoms among the US population: a mediation analysis via lipid indices

BackgroundCardiovascular diseases (CVD), chronic kidney disease (CKD), and lipids are positively correlated with the presence of depressive symptoms. However, investigation into the complex link that exists between cardiorenal syndrome (CRS) and lipid indices and depression remains scarce.MethodsThis study analyzed data from 11, 729 adults in the National Health and Nutritional Examination Surveys from 2005 to 2018. Weighted regression analysis was employed to examine the relationships between CRS and depression, CRS and the Patient Health Questionnaire-9 score, and lipid indices with depression. The restricted cubic spline analysis was used to determine whether there is a linear association between lipid indices and depression. Smooth curve fitting was employed to illustrate the relationship between lipids, depression, and cardiorenal diseases. Subgroup and sensitivity analyses were also conducted to enhance the stability of the results. Finally, we applied mediation analysis to explore whether the Atherogenic Index of Plasma (AIP), triglyceride glucose (TyG) index, and remnant cholesterol (RC) mediate the association between CRS and depression.ResultsAfter applying propensity score matching (PSM), 1,509 adults remained in the study. After PSM, more remarkable results were rendered that CRS was associated with depression compared with non-CRS (OR: 1. 240, 95% CI: 1. 237 ~ 1. 243), only-CVD (OR: 0. 646, 95% CI: 0. 644 ~ 0. 649), and only-CKD (OR: 1.432, 95% CI: 1.428 ~ 1.437) in a fully corrected model. Smooth curve fitting shows that the intersection point of the lines of CRS and non-CRS occurs at a higher value on the horizontal axis than the intersection point of the lines representing CVD and non-CVD. In the fully corrected model, AIP, TyG, and RC did not independently mediate the association between CRS and depression.ConclusionThere was a significant association between CRS and depression and a linear relationship between AIP, TyG, and RC and depression. However, the above lipid indicators did not mediate the association between CRS and depression.Graphical

Effect of Dietary Olive Leaf Integration on Qualitative Characteristics of Sheep Cheese During Ripening

Olive leaf by-products may be an important feed source for ruminants in the Mediterranean area, due to their nutritional value and high levels of functional metabolites. Additionally, their use can enhance the environmental and economic sustainability of the productions. To evaluate the effect of olive leaf supplementation on the fatty acid profile of sheep cheese, two farms with Comisana breed sheep with free access to pasture and fedwith 300 g/head/day of concentrate were considered. One farm supplemented the feed with clover hay ad libitum (NOL) and the other farm replaced hay with olive leaves (OLI) in the autumn period. Cheese analyses were performed at 15, 30, and 60 days of ripening. Saturated fatty acids were lower in OLI cheese than NOL cheese, while MUFA and PUFA n-3 and n-6 were higher in OLI cheese. Myristic acid (C14:0) and palmitic acid (C16:0) were lower in OLI cheese compared to NOL (8.31% vs. 8.90% and 21.52% vs. 24.95%, respectively), while oleic acid (C18:1 cis-9) was higher in OLI cheese (20.66% vs. 18.78%). Also, CLA cis-9 trans-11 (0.98% vs. 0.84%), and other isomers were higher in OLI cheese. Health indexes, such as the thrombogenic and atherogenic index, were lower in OLI than in NOL cheese (1.96 vs. 2.38 and 1.69 vs. 2.05, respectively) showing the improvement in the health quality of cheese due to olive leaf integration in directly on farm sheep feeding.

Metabolic Effects of Loquat Juice (Eriobotrya japonica Lindl Mkarkeb Variety) on Lipid Homeostasis, Liver Steatosis, and Oxidative Stress in Hyperlipidemic Mice Fed a High-Fat–High-Fructose Diet

Background: Loquat fruit is consumed for its flavorful taste and a rich array of health-promoting compounds like phenolics, flavonoids, and carotenoids. This study aimed at the biochemical characterization of fresh juice from the Moroccan Mkarkeb variety of loquat and evaluating its effects on lipid homeostasis and liver steatosis in hyperlipidemic mice. Methods: The biochemical characterization followed AOAC methods. In vivo study involved hyperlipidemic mice fed a high-fat, high-fructose diet for 6 weeks and treated with loquat juice at 3.5 and 7 mL kg−1 or fenofibrate at 4 mg·kg−1. The concentrations of lipids in plasma, liver, adipose tissue, feces, and bile and blood glucose levels were quantified. Liver steatosis was visually examined and confirmed histologically, and liver injury markers (AST, ALT, ALP, LDH, and TB) were measured. Liver oxidative stress was assessed by measuring MDA content and antioxidative enzyme activities. Results: Our findings indicate that fresh loquat juice is poor in fat and protein and contains moderate sugars with a low energy value (40.82 ± 0.25 kcal/100 g). It is also rich in minerals, vitamin C, phenolic acids, flavonoids, and carotenoids. The juice effectively restored lipid metabolism by enhancing reverse cholesterol transport and lowering LDL-cholesterol, triglycerides, and the atherogenic index. The studied juice decreases blood glucose and prevents weight gain and lipid accumulation in the liver and adipose tissue. The juice prevents lipotoxicity-induced liver injury, corrects toxicity markers, and improves the liver’s morphological and histological structures. It also reduces oxidative stress by lowering MDA and activating SOD and catalase. Conclusions: The juice holds high nutritional and medicinal value, potentially preventing lipid disorders and cardiovascular issues.

Hyper fibrinolysis state in COVID 19 and its correlation to lipid parameters

BackgroundCoronavirus disease 2019 (COVID 19) is associated with systemic effects involving especially the respiratory and cardiovascular system. The unique features of this condition are disseminated intravascular coagulation, excess fibrin degradation products due to abnormality in the coagulation system that could independently predict mortality. Abberations in lipid parameters that normally predict cardiovascular disease (CVD) were compared with D-dimer levels as risk markers in patients with COVID 19. MethodsA hospital based cross sectional study was conducted over a period of five months in patients aged 30 to 70 years diagnosed with COVID-19. The patients were categorised based on the D-dimer levels as: Group I <0.5μg/ml (Normal), Group II 0.5-2.0μg/ml (Intermediate high), Group III >2.0μg/ml (Very high). The lipid parameters, atherogenic indices were compared between the three groups. ResultsThe mean age of the selected COVID-19 patients was 49.3± 19.1 years of which 63 were males and 37 females (2:1). Significantly high D-dimer levels were detected which had a weak positive correlation with TG, Atherogenic Index Plasma (AIP). Significant rise in TC, LDL and Non-HDL was seen in Group II. Increasing trend of AIP was seen across the groups. D-dimer showed a weak positive correlation with TG, AIP and statistically non-significant negative correlation with rest of the lipid parameters. ConclusionThough an overall increase in D-dimer, TG and AIP was observed in COVID-19 patients, categorization based on D-dimer status detected lowering LDL and increasing AIP on deterioration of disease state.

A study of SGLT2 inhibitors on levels of plasma atherogenesis biomarkers in diabetes

ABSTRACT Background: Diabetes, a chronic metabolic disorder with microvascular and macrovascular complications. Metabolites of hyperglycemia mediates endothelial injury resulting in cascade of atherosclerosis. Atherosclerosis sets up plaque in vessel wall and obliterates the vascular lumen which results in stroke, myocardial infarction, and peripheral vascular disease. Biomarkers like IL-6, hsCRP, fibrinogen are correlated with cardiovascular disease. In our study, we use non-invasive tool to predict the CVD risk like atherogenic index of plasma, Triglyceride to high-density lipoprotein, and triglyceride glucose index. Methods: This is a prospective observational study on type 2 diabetes patients on SGLT2 inhibitors attending medicine departments. Data was collected on disease duration, anthropometry, fasting and post prandial glucose, HbA1C, lipid profile at initial visit and after 6 months. Atherosclerosis indices were compared accordingly. Results: Among 300 patients enrolled, mean age was 44±6.41 yrs. Triglycerides was 143±4.6mg/dl, after 6 months was123±6.1 with significance(p&lt;0.01). Low-density Lipoprotein(LDL) was 116 ±12.5mg/dL and after 6 months was 123±17which was significant(p&lt;0.01). High-density Lipoprotein (HDL) at baseline was 37.9±2.6 mg/dL,at 6 months 49±3.6 with significance (p&lt;0.01). Atherogenic index of plasma, baseline was 0.227±0.03, at 6 months was 0.040±0.040 with significance(p&lt;0.01). Triglyceride glucose index(TyG), baseline was 5±0.05 and 6 months was 4.8±0.04 with significance(p&lt;0.01). Triglyceride to HDL(TG:HDL), baseline was 3.7±0.2 and at 6 months was 2.56±0.2 with significance (p&lt;0.01). Conclusion: From our study, we observed that SGLT2 inhibitor shows significant improvement in glycemic profile in addition to lipid profile. SGLT2 inhibitor lowered atherogenic indices.

Atherogenic Index of Plasma (AIP): The Most Accurate Indicator of Overweight and Obesity Among Lipid Indices in Type 2 Diabetes-Findings From a Cross-Sectional Study.

This study aimed to evaluate the relationships of conventional and calculated lipid indices with obesity or overweight in patients with type 2 diabetes (T2D). In this cross-sectional study, all participants were categorised into three groups: normal weight (18 ≤ BMI < 25), overweight (25 ≤ BMI < 30) and obese (BMI ≥ 30). Conventional lipid indices, including triglyceride (TG), total cholesterol, LDL-C and HDL-C, were measured. Lipid indices, including the atherogenic index of plasma (AIP), non-HDL-C, TC/HDL-C, LDL-C/HDL-C, non-HLD-C/HDL-C (atherogenic index, AI) and lipoprotein combine index (LCI), were calculated. The associations of these lipid indices with obesity and overweight status were evaluated using univariate and multivariate multinomial logistic regression analyses. In this study, 2661 patients with T2D, including 651 patients with normal weight, 1144 with overweight, and 866 with obesity, were recruited. According to a multinomial logistic regression analysis after adjustment for multiple confounders, the odds ratio (OR) was greater for the AIP than for other conventional and calculated lipid indices in overweight and obese patients with T2D. The AIP had a significant relationship with overweight, with an OR of 4.79 (95% CI: 1.65-13.85), and it had a significant relationship with obesity, with an OR of 13.64 (95% CI: 3.96-47.04). According to the ROC curve, with a cut-off value of 0.68, AIP could predict obesity with 82% sensitivity and 55% specificity (AUC = 0.770, 95% CI: 0.729-0.812, p < 0.001). Compared with other conventional and calculated lipid markers, the AIP is most strongly associated with obesity and overweight in patients with T2D.

Mushroom and Kefir Functional Characterizations: Hypolipidemia and Gut Microbiota Modulations in Rat Models

ABSTRACTHyperlipidemia is a malnutrition disease associated with different lifestyle factors mainly high fat/cholesterol foods consumption and less physical activity. Consumption of high fiber foods (prebiotic sources) additionally to gut microbiota (GM; probiotics species) could overcome hyperlipidemia and its associated risks. Prebiotics and probiotics are known by protective effects in different diseases like diabetes, inflammatory bowel diseases, and cardiovascular diseases. Mushroom and kefir milk (KM) are known for their high pre/probiotic nutritional values depending on many factors, for example, eating levels and/or conditions. Therefore, this study aimed to measure the potential health benefits of dried powdered mushrooms (DPM) supplemented with KM between hyperlipidemia rats in association with lipid profile, atherogenic index (AI), and GM profile. Rats were randomly divided into main negative control healthy group (G1; −ve), positive control hyperlipidemia (G2; +ve) and three hyperlipidemia groups (G3:G5) fed DPM at 2.5%, 5%, and 10% of rats' diet additionally to 5% KM (DPM + 5% KM) each, respectively. The collected blood samples used for glucose, lipid profile (cholesterol, triglycerides, high‐density lipoprotein cholesterol, and low‐density lipoprotein cholesterol), and AI in addition to fecal sample for GM and short‐chain fatty acids (SCFAs). Collected data illustrated that body weight, blood glucose, lipid profile, GM (Bifidobacteria and Lactobacillus vs. Clostridium histolyticum), AI, and SCFAs were improved between hyperlipidemia fed 5% both PDM + KM (p ≤ 0.05) at the best levels. In conclusion, same DPM/KM levels have broad development as functional active foods that could lower hyperlipidemia incidence and promotes intestinal health; however, much more human studies are needed.

Evaluation of serum apolipoprotein concentrations and atherogenic indices in menopausal and premenopausal women in Nkwelle-Ezunaka

Background of study: The hormonal change in menopause affects lipid metabolism which could lead to dyslipidaemia, a risk factor for cardiovascular disease. Aim of study: To evaluate the levels of apolipoprotein A1, apolipoprotein B, Castelli risk index-1, Castelli risk index-11, atherogenic index of plasma and atherogenic coefficient in menopausal and premenopausal women. Materials and Methods: In this cross-sectional study ninety females were selected which consisted of 45 premenopausal, and 45 menopausal women using simple random sampling technique. Levels of apolipoprotein A1 and B were determined spectrophotometrically using enzyme linked immunosorbent assay (ELISA). Atherogenic indices were calculated with their respective formulas. Results: There was no significant difference in the mean levels of apo B (134.83±28.90 vs 130.73±30.55; p&gt;0.05), apo A1, atherogenic index of plasma, Castelli risk index-1, Castelli risk index-11 and atherogenic coefficient in the menopausal women compared with the premenopausal women but the mean values of both groups were outside the normal range of apo B, Castelli risk index-1, atherogenic index of plasma and atherogenic coefficient. Conclusion: Apo B, atherogenic index of plasma, Castelli risk index-1 and atherogenic coefficient are better indicators of cardiovascular risk.

The combined predictive power of the atherogenic index of plasma and serum glycated albumin for cardiovascular events in postmenopausal patients with acute coronary syndrome after percutaneous coronary intervention

BackgroundGlycated Albumin (GA) and atherogenic index of plasma (AIP) are two important biomarkers that respectively reflect lipid and glucose levels. Previous research has revealed their roles in cardiovascular diseases (CVD) and diabetes. However, their combined predictive ability in forecasting cardiovascular events (CVE) after percutaneous coronary intervention (PCI) among postmenopausal acute coronary syndrome (ACS) patients remains insufficiently studied.MethodsBased on the levels of AIP (AIP-L and AIP-H) and GA (GA-L and GA-H), four groups were used to categorize the patients. The CVE assessed included cardiac death, nonfatal myocardial infarction (MI) and nonfatal stroke. To evaluate the relationship between AIP, GA, and CVE, multivariate Cox regression analyses were performed.Results98 patients (7.5%) experienced CVE during follow-up. AIP and GA were revealed as strong independent predictors of CVE through multivariate analysis (AIP: HR 3.324, 95%CI 1.732–6.365, P = 0.004; GA: HR 1.098, 95% CI 1.023–1.177, P = 0.009). In comparison to those in the initial group (AIP-L and GA-L), the fourth group (AIP-H and GA-H) of patients exhibited the greatest CVE risk (HR 2.929, 95% CI 1.206–5.117, P = 0.018). Derived from the model of baseline risk, the combination of AIP + GA significantly enhanced the AUC, meanwhile combining AIP and GA levels maximized prognostic accuracy in the baseline risk model.ConclusionsThis study found that the combined measurement of AIP and GA significantly enhanced the predictive capability for CVE following PCI in postmenopausal ACS patients. By integrating these two biomarkers, it became possible to more accurately identify high-risk individuals and provided clinicians with new predictive tools for postmenopausal ACS patients in risk assessment and management.

Triglyceride and Glucose Index as an Optimal Predictor of Metabolic Syndrome in Lebanese Adults.

Background: Globally, the prevalence of metabolic syndrome (MetS) is on the rise, especially in Arab countries, which emphasizes the need for reliable ethnic-specific biochemical screening parameters. Methods: Two hundred twenty-one Lebanese adults were enrolled in this cross-sectional study. Biochemical parameters including Homeostasis Model Assessment (HOMA), Triglyceride and Glucose index (TyG), ratio of Triglycerides to High-Density Lipoprotein Cholesterol (TG/HDL-C), Atherogenic Index of Plasma (AIP), and Visceral Adiposity Index (VAI) were assessed for their prediction of MetS. Analysis of covariance, logistic regression, expected-versus-observed case ratio were used to determine model calibration, concordance statistic, area under the receiver operating characteristic curve (AUC) and 95% confidence intervals (CIs), sensitivity, specificity, and negative and positive predictive values (PPV, NPV). Results: The prevalence of MetS was 44.3%. All biochemical parameters were significantly associated with MetS, with a strong model discrimination (c-statistic between 0.77 and 0.94). In both sex categories, TyG best predicted MetS (females: cut-off value, 8.34; males: cut-off value, 8.43) and showed good estimation among females, but overestimation among males. HOMA had the lowest discriminatory power in both sex categories. Conclusions: This study suggests that TyG best predicts MetS, while HOMA has the lowest predictive power. Future larger studies need to focus on harmonizing ethnic specific cut-offs and further validating our results.
