Novel Insights into Causal Effects of Serum Lipids and Apolipoproteins on Cardiovascular Morpho-Functional Phenotypes.

Previous observational studies have explored the association between serum lipids, apolipoproteins, and adverse ventricular/aortic structure and function. However, whether a causal link exists is uncertain. This study employed a two-sample Mendelian randomization (MR), colocalization, reverse, and multivariable MR (MVMR) approach to examine the causal associations among five serum lipids, two apolipoproteins, and 32 cardiac magnetic resonance (CMR) traits. Utilizing single-nucleotide polymorphisms (SNPs) linked to serum lipids and apolipoproteins as instrumental variables. CMR traits from seven independent genome-wide association studies served as preclinical endophenotypes, offering insights into aortic and cardiac structure/function. The primary analysis utilized a random-effects inverse variance method (IVW), followed by sensitivity and validation analyses. In the primary IVW MR analyses, genetically predicted low-density lipoprotein cholesterol (LDL-C) levels were positively correlated with increased descending aorta strain (DAo strain) (β = 0.098; P = 2.69E-07) and ascending aorta strain (AAo strain) (β = 0.079; P = 5.19E-05). Genetically predicted high-density lipoprotein cholesterol (HDL-C) levels were positively correlated with left ventricular radial peak diastolic strain rate (LV-PDSRll) (β = 0.176; P = 2.89E-05) and the left ventricular longitudinal peak diastolic strain rate (LV-PDSRrr) (β = 0.059; P = 2.44E-06), and negatively correlated with left ventricular regional wall thickness (LVRWT). While apolipoprotein B (ApoB) levels were positively correlated with AAo strain (β = 0.076; P = 1.16E-05), DAo strain (β = 0.065; P = 2.77E-05). A shared causal variant was identified to demonstrate the associations of ApoB with AAo strain and DAo strain using colocalization analysis. Sensitivity analyses confirmed the robustness of these associations. Targeting lipid and apolipoprotein levels through interventions may provide novel strategies for the primary prevention of CVDs.

Relevance of combined influence of nutritional and inflammatory status on non-alcoholic fatty liver disease and advanced fibrosis: A mediation analysis of lipid biomarkers.

This study aimed to investigate the relationship between advanced lung cancer inflammation index (ALI) and non-alcoholic fatty liver disease (NAFLD) and advanced liver fibrosis (AF). A total of 5642 individuals from the National Health and Nutrition Examination Survey (NHANES) between 2017 and 2020 were examined. Limited cubic spline regression model, and weighted logistic regression were employed to determine if ALI levels were related to the prevalence of NAFLD and AF. Additionally, a mediating analysis was conducted to investigate the role of lipid biomarkers, such as total cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C), in the effects of ALI on the prevalence of NAFLD and AF. After adjusting for potential confounders, a significant positive association was found between ALI with NAFLD and AF prevalence. Compared with those in ALI Tertile 1, participants in Tertile 3 had higher odds of NAFLD prevalence (odds ratio [OR]: 3.16; 95% confidence interval [CI]: 2.52-3.97) and AF (OR: 3.17; 95% CI: 2.30-4.36). Participants in both Tertile 2 and Tertile 3 had lower odds of developing AF (P for trend=0.005). Moreover, we discovered a nonlinear association between ALI and NAFLD. An inflection point of 74.25 for NAFLD was identified through a two-segment linear regression model. Moreover, TC and HDL-C levels mediated the association between ALI and NAFLD by 10.2% and 4.2%, respectively (both P<0.001). Our findings suggest that higher ALI levels are positively associated with an increased prevalence of NAFLD and AF, partly mediated by lipid biomarkers.

Metabolic disorders in patients with chronic thromboembolic pulmonary hypertension

To analyze the relationship between metabolic disorders and obesity with hemodynamic parameters and the severity of the condition of patients with chronic thromboembolic pulmonary hypertension (CTEPH) based on the POLET register. The study included patients with CTEPH from the POLET register. Data from medical history, lipid profile, glycemia, uric acid level, weight, height, functional class (FC), distance in the 6-minute walk test (6MWT), echocardiography, and right heart catheterization were used for analysis. The study included 84 patients 60±14 years old, including 45 men. The majority of patients had FC III - 51 (65%), which corresponded to 6MWT - 338±113 m. Nineteen (23%) people had experience in taking PAH specific therapy, 37 (46%) had cardiovascular comorbidity. In the general group, the body mass index (BMI) was 25.7±4.5 kg/m2, and normal glycemia, lipid profile, and uric acid levels were also determined. mPAP was 51±12 mmHg, RA area was 25.5 (20; 30) cm2. Correlations were identified between: RA area and the level of total cholesterol (r=0.60; p<0.01), triglycerides (r=-0.24; p<0.001), LDL cholesterol (r=0.75; p=0.04), uric acid (r=0.75; p=0.03); total cholesterol and 6MWT (r=0.44; p=0.04). Analysis of metabolic disorders, FC and comorbidity revealed differences between FC III and IV groups in the level of HDL cholesterol (p=0.02) and triglycerides (p<0.01). The POLET registry includes mainly older patients. Severe FC (87% - III and IV) may be a result of the older age and the presence of concomitant pathology in almost half of the patients. The discovered relationships between the area of RA and FC with lipid and purine metabolism were discovered for the first time, however, they correspond to the direction of the world scientific researches, are important due to the use of these indicators in the scale for calculating the risk of death in patients with PAH and require further development.

Genetic Susceptibility to Hidradenitis Suppurativa and Predisposition to Cardiometabolic Disease.

Hidradenitis suppurativa (HS) is associated with an increased prevalence of cardiovascular diseases compared with the general population. Any association between polygenic risk for HS, risk of incident cardiometabolic outcomes, and the plasma proteome is unclear. To investigate the genetic correlation between HS and cardiometabolic disease. This cohort study used a polygenic risk score (PRS) for HS to examine the risks of coronary artery disease (CAD) and diabetes and identify changes in the plasma proteome in individuals of European ancestry from the UK Biobank. Participants were enrolled from January 1, 2006, to December 31, 2010. End of follow-up was January 1, 2023. Correlations were assessed between HS susceptibility and cardiometabolic traits using linkage disequilibrium score regression. Odds ratios were assessed in logistic regressions. The risk of incident CAD and diabetes was estimated in cause-specific survival models designed as time-to-event analyses. The PRS for HS. Main outcomes were CAD and diabetes diagnosis measured by logistic regressions and incident disease measured by Cox proportional hazards regression models adjusted for sex, age, body mass index, and smoking status. The study included 391 481 individuals (median [IQR] age, 58 [51-64] years; 209 235 [53%] female). Genetic variants for HS correlated significantly with variants associated with CAD, diabetes, and plasma levels of high-density lipoprotein cholesterol, triglycerides, and C-reactive protein. Compared with the low-risk group, a high PRS for HS (≥75th percentile) conferred odds ratios of 1.09 (95% CI, 1.06-1.12; P < .001) for CAD and 1.13 (95% CI, 1.10-1.17; P < .001) for diabetes. Estimates remained consistent when examining only incident CAD and diabetes. The PRS for HS was significantly associated with altered expression of 58 plasma proteins. Integrating this proteomic profile and the PRS for HS in a machine learning model improved prediction of CAD and diabetes compared with a reference model based on sex, age, and body mass index. These findings suggest that a high genetic risk of HS is associated with increased risk of subsequent CAD and diabetes and altered composition of the plasma proteome. Additional investigation into the identified proteins and their potential roles as drug targets is warranted.

Efficacy of Food Industry By-Product β-Glucan/Chitin–Chitosan on Lipid Profile of Overweight and Obese Individuals: Sustainability and Nutraceuticals

Fat-binding nutraceutical supplements have gained considerable attention as potential cholesterol-lowering strategies to address dyslipidemia in overweight and obese individuals. This study aimed to evaluate the effects of a polysaccharide-rich compound containing β-glucan/chitin–chitosan (βGluCnCs) on lipid profiles and lipoprotein function. In a prospective, two-arm clinical trial, 58 overweight and obese individuals were randomized to receive either 3 g/day of βGluCnCs or a placebo (microcrystalline cellulose) for 12 weeks. Serum lipids and lipoprotein functions were assessed at baseline and at 4-week intervals throughout the study. The administration of βGluCnCs led to a significant increase in HDL cholesterol (HDLc) levels and improved HDLc/non-HDLc and HDLc/total cholesterol (TC) ratios, while reducing apolipoprotein B (ApoB) levels (p &lt; 0.05). However, the intervention did not affect HDL particle diameter, particle number, or lipoprotein functionality. Women demonstrated greater sensitivity to changes in HDLc during βGluCnCs supplementation, whereas men exhibited a significant reduction in ApoB levels. When stratified by baseline LDL cholesterol (LDLc) levels (cut-off: 130 mg/dL), the increase in HDLc and the ApoA1/ApoB ratio was found in the low-LDL group. In contrast, the high-LDL group experienced a significant reduction in atherogenic non-LDLc and LDLc, along with an improvement in HDL’s antioxidant capacity after βGluCnCs intervention. These changes were not statistically significant in the placebo group. In conclusion, our study demonstrated that daily supplementation with βGluCnCs significantly improved lipid profiles, with effects that varied based on sex and baseline LDLc levels.

Hypomagnesaemia and Relationship Lipid Profile in Type 2 Diabetes Patients at Janzur Hospital in Libya.

Type 2 diabetes mellitus (T2DM) is associated with increased morbidity and mortality due to the development of complications, especially due to poor glycemic control. Magnesium (Mg) is a crucial element in human health, and its deficiency plays a critical role in the development of lipid abnormalities and the initiation of diabetic complications. The study aimed to evaluate the correlation of hypomagnesemia (Mg) with the alteration of lipid profile patterns and investigate the adverse effects of glycemic control and body mass index (BMI) on magnesium levels among patients with T2DM. A total of 163 subjects whose ages ranged between 35-60 years for both sexes (males and females) were included in this study: 90 type II diabetic patients (40 males and 50 females) and 73 healthy individuals (34 males and 39 females) in Tripoli region, Western Libya. Blood glucose, HbA1c, Magnesium, and lipid profile parameters were biochemically estimated in the study along with the measurement of BMI. All the results were statistically analyzed using SPSS version 25 for applying one-way ANOVA and Person's correlation coefficient tests. The study revealed a significant decrease in serum magnesium levels (1.59 ± 0.47 mg/dL) in T2DM patients compared to the control group (2.21 ± 0.70 mg/dL) (p &lt; 0.01). Significantly elevated levels of blood glucose (140.6 ± 30.95 mg/dL vs. 89.80 ± 12.62 mg/dL, p &lt; 0.01), HbA1c (7.27 ± 2.62% vs. 5.32 ± 0.65%, p &lt; 0.01), cholesterol, triglycerides and LDL cholesterol also observed in T2DM patients compared to healthy individuals. Conversely, HDL cholesterol levels were significantly lower in the T2DM group than in controls (24.44 ± 8.88 mg/dL vs. 47.06 ± 8.75 mg/dL, p &lt; 0.01). There is a relationship between hypomagnesemia, glycemic control, and changed lipid profile in T2DM patients. Further, our results revealed a strong relationship between increased BMI and unfavorable alterations in all biochemical parameters examined.

Metabolic outcomes in women 6 months and 2 years after preeclampsia versus normotensive pregnancy: A P4 study.

Preeclampsia is associated with an increased risk of long-term cardiometabolic disease; however, little is known regarding metabolic factors in the early postpartum years potentially contributing to these health disparities. This study aimed to compare body composition, serum biochemical parameters, energy balance and diet 6 months and 2 years after normotensive pregnancy versus preeclampsia. This is the longitudinal metabolic sub-study of the Postpartum Physiology, Psychology and Paediatric cohort study. Women were assessed 6 months and 2 years after normotensive pregnancy (n = 118) and preeclampsia (n = 47). Metabolic measures included anthropometry, body composition via bioelectrical impedance analysis, serum biochemical parameters, diet via a food recall diary, and 24-h energy expenditure using SenseWear Armbands. Two years postpartum, women after preeclampsia continued to have significantly higher weight (median 67.1 kg vs. 63.1 kg, p = .04) compared to normotensive pregnancies, in addition to higher LDL cholesterol levels (2.7 ± 0.8 mmol/L vs. 2.4 ± 0.6 mmol/L, p = .03). These women were also more likely to have an elevated HOMA-IR score ≥2.08 (44% vs. 19%, p = .01). For all women in our study, waist-to-hip ratio, percent fat mass and activity-associated energy expenditure improved overtime. However, HDL cholesterol levels deteriorated, and excess saturated fat and sodium intake persisted from 6 months postpartum. Therefore, two years after preeclampsia, women remain at greater metabolic risk than their normotensive counterparts, with greater weight, LDL cholesterol and markers of insulin resistance, potentially contributing to long-term cardiovascular morbidity and requiring early intervention.

Anti-Hyperlipidemic Effect of Ruta chalepensis Ethanolic Extract in Triton WR-1339-Induced Hyperlipidemia in Rats

High levels of fats like triglycerides and cholesterol in the blood can cause cardiovascular diseases, prompting the search for safer, natural treatments. This study investigates the efficacy of Ruta chalepensis ethanol extract in lowering cholesterol levels using a rat model of hyperlipidemia induced by Triton WR-1339. Leaves and flowers of R. chalepensis were extracted with ethanol, and LC-MS analysis revealed high levels of quercetin (9.5%), 2,2-Dimethyl-3-methylidenebicyclo [2.2.1] heptane (8.1%), and other compounds, with monoterpenes being the most common class. Male Wistar rats received doses of the extract at 20 and 40 mg/kg, while fenofibrate (100 mg/kg) was the positive control. After 20 h, plasma lipid levels were significantly affected, showing a 72.1% reduction in total cholesterol for the 40 mg/kg group (p &lt; 0.01) and a 67.6% reduction for the 20 mg/kg group (p &lt; 0.01). High-density lipoprotein cholesterol levels decreased by 68.8% in the 40 mg/kg group (p &lt; 0.01) and 58.6% in the 20 mg/kg group (p &lt; 0.01). Low-density lipoprotein cholesterol saw reductions of 67.3% (p &lt; 0.001) in the 40 mg/kg group and 60.4% (p &lt; 0.01) in the 20 mg/kg group. Triglycerides dropped by 90.6% in the 40 mg/kg group (p &lt; 0.001) and 86.7% in the 20 mg/kg group (p &lt; 0.001). Overall, the results highlighted a stronger anti-hyperlipidemic effect in the 40 mg/kg group across all lipid parameters measured. The extract outperformed fenofibrate, particularly at the higher dose. These results imply that R. chalepensis extract is a promising natural alternative for managing hyperlipidemia.

7055 Metabolic Disorders In Thalidomide Embryopathy

Abstract Disclosure: A. Tanabe: None. Thalidomide embryopathy (TE) is a congenital limb defect that occurs in neonates born to pregnant women who have taken thalidomide. Typical abnormalities of the TE are upper limb hypoplasia and and/or auditory dysfunction. In Japan, thalidomide was marketed as an agent for sleep-induce and digestive ulcers from 1958 to 1962. Up to now, approximately 290 cases have been certified and are supported by the government as drug-induced disease. Currently, many of the victims are in their late 50s, and in addition to congenital disabilities, various health issues such as lifestyle-related diseases can be developed. We investigated their metabolic condition using data of medical health checkup between 2017 and 2018. Fifty-one Japanese cases of TE (28 men and 23 women) were included in this study. The mean age was 56.4±1.6 years in men and 55.9±1.2 years in women. The prevalence of upper limb deformities was 64% in men and 74% in women; the remaining patients had only hearing impairment. The mean body mass index (BMI) was 22.7±2.1 in men and 22.5±4.0 in women. Eleven percent of men and 17% of women had a BMI between 25-30, while 9% of women and no men had a BMI of 30 or greater. Liver dysfunction was seen in 32% of men and 9% of women. The mean high-density lipoprotein cholesterol level was 60±17 mg/dL in men and 68±18 mg/dL in women. The mean low-density lipoprotein (LDL) cholesterol level was 120±28 mg/dL in men and 136±35 mg/dL in women, with 25% of men and 48% of women had LDL level of 140 mg/dL or greater. The mean triglyceride (TG) level was 144±85 mg/dL in men and 116±61 mg/dL in women, with 43% of men and 17% of women had a level of 150 mg/dL or greater. The mean HbA1c level was 6.0±1.0% in men and 5.9±0.4% in women. The prevalence of impaired glucose tolerance was 25% in men and 13% in women. Fatty liver (FL) evaluated by ultrasonography or CT scan was 61% in men and 39% in women. The patients with FL showed significantly high body fat percentage and TG level in men, high alanine aminotransferase, γ-glutamyl transpeptidase and TG levels in women, respectively, compared to the patients without FL. The prevalence of hypertriglyceridemia was significantly higher in men with FL compared with men without FL. There was no significant difference in with or without the upper limb abnormalities in both groups. Although without obvious overweight, more than 40 % of the patients had dyslipidemia and 50% of the patients had FL. The limb abnormalities can result in movement limitations however other factors may be involved in the development of metabolic disorders in TE. The results of this study provide valuable information for future health management in thalidomide embryopathy.

7279 Survodutide and Semaglutide Both Induce Weight Loss but Show Different Effects on Food Preference and Dyslipidemia in the Free Choice Diet-induced Obese Hamster Model

Abstract Disclosure: F. Briand: Employee; Self; Physiogenix. R. Augustin: Employee; Self; Boehringer Ingelheim. K. Bleymehl: Employee; Self; Boehringer Ingelheim. T. Zimmermann: Employee; Self; Boehringer Ingelheim. T. Klöckener: Employee; Self; Boehringer Ingelheim. T. Klein: Employee; Self; Boehringer Ingelheim. Introduction: Semaglutide, a GLP-1 receptor agonist, and survodutide, a GCGR/GLP-1R dual agonist, have demonstrated significant weight loss in patients with obesity. To test whether this weight loss is associated with changes in food preference and improvement in dyslipidemia, we evaluated semaglutide and survodutide in the free choice diet-induced obese and dyslipidemic hamster, a model with a human-like lipoprotein metabolism. Methods: Obesity and dyslipidemia were induced with a 20-week free choice diet, which presents hamsters with a choice between control chow diet or high fat/cholesterol diet, and normal water or 10% fructose water. Obese hamsters were then kept on this free choice diet and treated subcutaneously once daily with vehicle, semaglutide 15 nmol/kg or survodutide 15 nmol/kg for 5 weeks. Results: Compared with vehicle, semaglutide and survodutide led to a 17% and 11% body weight reduction, respectively (both p&amp;lt;0.001 vs vehicle). Compared to vehicle, both chow diet and high fat diet intakes were significantly lower during the first week of semaglutide treatment, but then returned to baseline values. However, semaglutide significantly increased normal water intake and reduced fructose-enriched water intake during the whole treatment period (both p&amp;lt;0.001). Survodutide had a different effect, as it did not alter chow diet and normal water intakes, but significantly reduced high fat diet and fructose-enriched water intakes during the 5-week treatment period. Semaglutide and survodutide significantly reduced plasma insulin levels and the HOMA-IR index of insulin resistance (both p&amp;lt;0.01 vs. vehicle). Both semaglutide and survodutide significantly reduced plasma total cholesterol levels by 24% and 41%, respectively (both p&amp;lt;0.001). This hypocholesterolemic effect led to lower HDL-cholesterol levels (-25%, p&amp;lt;0.001) but unchanged LDL-cholesterol levels for hamsters treated with semaglutide. In contrast, in hamsters treated with survodutide, cholesterol lowering was observed in all lipoprotein fractions, including LDL-cholesterol (-39%, p&amp;lt;0.001). Conclusion: Semaglutide and survodutide both induce weight loss and lower HOMA-IR, but have different effects on food preference and dyslipidemia in the obese hamster model; such effects may be attributed to the GCGR agonism of survodutide. These preclinical data highlight the potential metabolic benefits of the GCGR/GLP-1R dual agonist survodutide for the treatment of obesity and related metabolic comorbidities. Presentation: 6/3/2024

Impact of High-Dose Supplemental Paprika Extract Feeding on Egg Storage and Biochemical Parameters in Laying Hens.

This study aimed to evaluate the effects of paprika extract supplementation on egg storage and blood biochemical parameters in 63-week-old Rhode Island Red (RIR) and Silky Fowl (SF) hens. The hens were divided into three groups: a control group with a basal diet and two groups receiving the basal diet with paprika extract. The trial lasted 28 days, with egg quality (yolk color and albumen pH) assessed after storing eggs at 25 °C for 21 days. A total of 144 eggs were used in 42 treatments (two breeds, three diets, and seven storage periods) with three eggs examined each (four eggs were used on day 0 and five eggs on day 21). Additionally, the yolk carotenoid content, yolk color, and pH of eggs stored at 4 °C and 25 °C were compared. Results showed that yolk color fan score (YCFS) decreased with storage, and SF had a higher albumen pH than RIR, with both breeds exhibiting an increase in pH over time. HDL cholesterol (HDL-C) levels and the HDL-C to total cholesterol ratio were significantly influenced by breed, diet, and their interaction. The HDL-C level in SF was affected linearly and quadratically by diet, while no such trend was observed in RIR. The study concluded that paprika extract affects egg quality and blood lipid profiles differently in different breeds, highlighting breed-specific responses to dietary supplementation.

Examining the causal association between moderate alcohol consumption and cardiovascular risk factors in the Taiwan Biobank: a Mendelian randomization analysis.

The Mendelian randomization approach uses genetic variants as instrumental variables to study the causal association between the risk factors and health outcomes of interest. We aimed to examine the relation between alcohol consumption and cardiovascular risk factors using two genetic variants as instrumental variables: alcohol dehydrogenase 1B (ADH1B) rs1229984 and aldehyde dehydrogenase 2 (ALDH2) rs671. Using data collected in the Taiwan Biobank-an ongoing, prospective, population-based cohort study-our analysis included 129,032 individuals (46,547 men and 82,485 women) with complete data on ADH1B rs1229984 and ALDH2 rs671 genotypes and alcohol drinking status. We conducted instrumental variables regression analysis to examine the relationship between alcohol drinking and body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose, glycated hemoglobin (HbA1c), triglycerides, high-density lipoprotein cholesterol (HDLc), and low-density lipoprotein cholesterol (LDLc). In the rs1229984-instrumented analysis, alcohol drinking was only associated with higher levels of SBP in men and lower levels of DBP in women. In the rs671-instrumented analysis, alcohol drinking was associated with higher levels of BMI, SBP, DBP, fasting glucose, triglycerides, HDLc and lower levels of LDLc in men; alcohol drinking was associated with higher levels of HDLc and lower levels of SBP, HbA1c, and triglycerides in women. Using Mendelian randomization analysis, some of our study results among men echoed findings from the previous systematic review, suggesting that alcohol drinking may be causally associated with higher levels of BMI, SBP, DBP, fasting glucose, triglycerides, HDLc, and lower levels of LDLc. Although alcohol drinking is beneficial to a few cardiovascular risk factors, it is detrimental to many others. The assumptions that underlie the Mendelian randomization approach should also be carefully examined when interpreting findings from such studies.

No causal relationship serum lipids on age-related hearing loss based on Mendelian randomized evidence

ObjectivesPresbycusis, or age-related hearing loss (ARHL) has been a common disability disease among the elderly population. It is particularly essential to identify the underlying role of related risk factors for ARHL diagnosis and treatment. Observational studies have shown that cardiovascular disease may be a factor in ARHL. Serum lipids are a key risk factor for cardiovascular disease. Therefore, it may be a potentially influencing factor for elderly deafness. We conduct the study to analyze the causal relationship between serum lipids and European elderly deafness. DesignUsing genetic variation data related to serum lipids (total cholesterol levels [TCL], total triglycerides levels [TGL], and lipoprotein fractions, including apolipoprotein A1 levels [APOA1L], apolipoprotein B levels [APOBL], high-density lipoprotein cholesterol levels [HDL], and low-density lipoprotein cholesterol levels [LDL]) as instrumental variables, the outcome events were summarized from the genome-wide association study data of elderly deafness, and Mendelian randomization (MR) analysis was used in our analysis. The relationship between serum lipids levels and ARHL was analyzed using five methods, including inverse variance weighted, weighted mode, MR-Egger, weighted median, and simple mode. The study aims to use bidirectional MR analysis. ResultsAmong all 5 methods, no significant causal effects were found between serum lipids (TCL OR = 0.936, p = .488; TGL OR = 0.955, p = 0.657; APOA1L OR = 0.864, p = .061; APOBL OR = 0.979, p = .786; HDL OR = 0.998, p = .979; LDL OR = 1.089, p = .281) and presbycusis. ConclusionThe findings of MR causal inference analysis did not support the causal relationship between presbycusis and serum lipids, including cholesterol, triglycerides, and lipoprotein fractions (APOA1L, APOBL, HDL and LDL).

Hypoglycemic activity of Garcinia mangostana L. extracts on diabetes rodent models: A systematic review and network meta-analysis.

Diabetes mellitus is a significant global health issue, and alternative treatments from natural products like Garcinia mangostana L. [Clusiaceae] or GM are being explored for their potential benefits. This study focused on evaluating the hypoglycemic effects of GM on diabetic rodent models. A comprehensive search was conducted in PubMed, Scopus, and Embase for studies reporting blood glucose levels within 2weeks as the primary outcome and changes in total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) as secondary outcomes. A network meta-analysis (NMA) was performed to determine the pooled effectiveness of each intervention, estimating the weighted mean difference (WMD) and 95% confidence interval (CI) from both direct and indirect evidence. The surface under the cumulative ranking curve (SURCA) was used to rank the interventions. Ten articles were identified, with nine included for quantitative analysis. All GM extracts showed greater effectiveness than the control in decreasing blood glucose levels within 2weeks. GM at 200mg/kg (GM200) was the top-ranked extract for reducing glucose levels beyond 2weeks and increasing HDL-C levels. The ethanol extract of GM at 200mg/kg (GME200) was the most effective for blood glucose reduction within 2weeks and for TC and TG reductions. The methanol extract of GM at 200mg/kg (GMM200) was the top-ranked extract for LDL-C reductions. GM and its extracts demonstrated significant hypoglycemic activity and improvements in lipid profiles in diabetic rodent models, highlighting their potential as therapeutic agents for the prevention and treatment of diabetes mellitus. Further research in human trials is warranted to confirm these findings and establish clinical applications. https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023426254.

Impact of high-sensitivity C-reactive protein on metabolic syndrome in an elderly population: Findings from a hospital-based cross-sectional study in J&amp;K, India

ABSTRACT Background: Due to affluent lifestyles, primary care physicians are concerned about metabolic syndrome (MetS). Inflammation and insulin resistance are caused by extra adipose tissue. Our study seeks to evaluate, taking into account numerous variables, the relationship between high-sensitivity C-reactive protein (hsCRP) levels and MetS in adults aged 50+ in Northern Kashmir, India. Materials and Methods: In Northern Kashmir, India, a hospital-based cross-sectional study looked into the relationship between hsCRP and MetS in people over 50. The recruitment process included people looking for basic healthcare services. Utilising modified NCEP-ATP III criteria, MetS was established. The association between MetS and hsCRP levels was evaluated statistically while taking into account various variables. Results: The waist circumference, body mass index, systolic and diastolic blood pressure, as well as the prevalence of hypertension, diabetes mellitus (DM), and dyslipidemia were all greater in those with MetS. While demonstrating decreased levels of high-density lipoprotein cholesterol (HDL-C), they also showed higher levels of high-sensitive C-reactive protein (hsCRP) and fasting plasma glucose. A study of correlations revealed a substantial inverse relationship between hsCRP and HDL-C. Elevated hsCRP levels were found to be substantially linked with MetS by the use of logistic regression, along with obesity, uric acid levels, hypertension, DM, and dyslipidemia. These results underline how crucial it is to keep an eye on these variables in order to recognize and treat MetS as soon as possible. Conclusion: Among this investigation, we found strong evidence that high- hsCRP, an independent risk factor for MetS, was present among middle-aged and elderly residents of the northern Kashmir region of India.

Dipeptidyl peptidase-4 inhibitors may lower body temperature: A case-control study

AimsDipeptidyl peptidase-4 inhibitors (DPP4i) enhance GABAergic transmission via the glucagon-like peptide-1 (GLP-1)/GLP-1 receptor pathway. Oral γ-aminobutyric acid (GABA) administration reduces body temperature in humans; thus, DPP4i may reduce body temperature in humans. Therefore, this study aimed to determine the effects of DPP4i administration on the body temperature of patients with type 2 diabetes (T2D). MethodsThis study included 128 outpatients with T2D who visited the hospital monthly from May to July 2022. The DPP4i group included 64 patients treated with DPP4i while the non-DPP4i group included 64 patients not treated with DPP4i. Body temperature was measured at the axilla point upon entry to the hospital and was compared between the two groups. ResultsThe means of age, body mass index, T2D duration, systolic blood pressure, diastolic blood pressure, serum creatinine level, casual triglyceride level, high-density lipoprotein cholesterol level, low-density lipoprotein cholesterol level, casual plasma glucose level, and glycated hemoglobin level were not significantly different between the two groups. The mean body temperatures (°C) were 36.1 ± 0.2 and 36.4 ± 0.17 in the DPP4i and non-DPP4i groups, respectively (p = 1.123 E-05). ConclusionsDPP4i reduced the body temperature of patients with T2D.
