Targets and Mechanisms of Resveratrol against Endothelial-Mesenchymal Transition in Atherosclerosis: A Network Pharmacology Analysis Combined with In vivo Experiments

Background: Atherosclerosis (AS) is a chronic inflammatory disease characterized by plaque formation and endothelial dysfunction. Under pro-inflammatory conditions, the endothelial-mesenchymal transition (EndMT) plays an important role in the pathogenesis of AS. Resveratrol (RES) is a natural polyphenol in traditional Chinese medicines, which has been proven to possess anti-AS effects. However, the mechanism of RES treating AS through EndMT is not clear at present. Methods: RES targets were screened using databases such as SwissTargetPrediction and TargetNet, and AS and EndMT targets were searched using databases such as OMIM and DisGeNET. With the help of Venny 2.1, the key targets were selected by intersection. Next, the protein-protein interaction (PPI) network was constructed through the STRING 11.0 platform and Cytoscape software; gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway annotations were performed using DAVID. Further, Cytoscape was used to construct a drug-component-gene target-pathway network diagram to identify the core components and genes. Subsequently, an AS rat model was established. The blood lipid level of rats was detected by an automatic biochemical analyzer, and the expression level of the target protein was measured by western blotting. Results: Through network pharmacology analysis, 37 potential targets for RES treating AS and EndMT were identified, and the core targets for RES treating AS consisted of AKT1, TNF, MIMP9, and PPARG. GO enrichment analysis indicated that the treatment of AS with RES mainly involved the migration and proliferation of epithelial and endothelial cells. The KEGG pathway enrichment analysis revealed that the enrichment of TNF and Rap1 signaling pathways was most significant. Besides, RES effectively reduced the levels of total cholesterol (TC), triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) in the serum of AS rats, increased the level of high-density lipoprotein cholesterol (HDL-C), and significantly cut down the atherosclerosis index (AI). Twist1, calponin, α-SMA and VE-cadherin were considered as EndMT indexes. The results of the western blot demonstrated that the protein levels of Twist1, calponin and α-SMA were significantly decreased, while the protein expression level of VE-cadherin was notably increased in rats treated with RES. Moreover, RES could also reduce the expression levels of Rap1 and Epac1 proteins. Conclusion: RES is an effective anti-AS drug. Briefly, RES can effectively improve the blood lipid level of AS patients, regulate the expression of EndMT-related proteins, and alleviate the dysfunction of endothelial cells. Notably, the functions of RES are closely associated with the EPAC1-Rap1 pathway.

Shugan Jiangzhi Decoction Alleviates Nonalcoholic Fatty Liver Disease (NAFLD) via Regulating AMPK/PPAR Signaling Pathway

Background: Non-alcoholic fatty liver disease (NAFLD) is considered the most common liver disease. Shugan Jiangzhi Decoction (SJD), a traditional Chinese medicine (TCM) formula which consists of six Chinese herbs, has been used for treating hyperlipidemia, obesity, and fatty liver in Guangdong Provincial Hospital of Traditional Chinese Medicine for over twenty years. Objective: This study aims to elucidate the chemical basis and the molecular mechanism of SJD against NAFLD. Methods: The main components of SJD were determined by High Performance Liquid Chromatography (HPLC). Then the high-fat diet (HFD)-induced NAFLD rat model was established. After treatment with different doses of SJD, the body weight of rats was measured weekly. On the last day of the experiments, the hepatic morphology, histopathology changes, and the serum lipid levels were detected. Then techniques of network pharmacology were employed to predict the anti-NAFLD mechanism of SJD. At last, the expression levels of proteins were measured by western blot to verify the mechanism. Results: Nine chemical constituents of SJD were identified from HPLC fingerprint spectrum. For the in vivo experiment, NAFLD rat model was constructed successfully by feeding high-fat diet (HFD) for 8 weeks. The following treatment with SJD for 6 weeks decreased the fatty droplet accumulation in the liver obviously. Meanwhile, the serum level of high-density lipoprotein cholesterol (HDL-c) was increased, while the levels of lowdensity lipoprotein cholesterol (LDL-c), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were decreased after SJD treatment (p < 0.05). The results of network pharmacology indicated that SJD might improve NAFLD via regulating the AMPK/PPAR signaling pathway. Then, the western blot assay confirmed that SJD activated the AMPK/PPAR signaling pathway in the liver of rats. Conclusion: SJD improves HFD-induced NAFLD in rats via AMPK/PPAR signaling pathway. Thus, our study suggests that SJD can serve as a therapeutic agent for the prevention and treatment of NAFLD.

Non-linear association of the platelet/high-density lipoprotein cholesterol ratio with bone mineral density a cross-sectional study

BackgroundNumerous studies have demonstrated shared risk factors and pathophysiologic mechanisms between osteoporosis and cardiovascular disease. High-density lipoprotein cholesterol (HDL-C) and platelets have long been recognized as crucial factors for cardiovascular health. The platelet to HDL-C ratio (PHR) combines platelet count and high-density lipoprotein cholesterol (HDL-C) level, It is a novel biomarker for metabolic syndrome and cardiovascular disease. The platelet to HDL-C ratio (PHR) possibly reflects the balance between proinflammatory and anti-inflammatory states in the body. Therefore, we hypothesized that changes in PHR ratios may predict a predisposition to pro-inflammatory and increased bone resorption. However, the relationship between the platelet to HDL-C ratio (PHR) and bone mineral density (BMD) remains insufficiently understood. This study aimed to elucidate the relationship between the platelet to HDL-C ratio (PHR) index and bone mineral density (BMD).MethodsData from the NHANES 2005–2018 were analyzed, excluding adults with missing key variables and specific conditions. Nonlinear relationships were explored by fitting smoothed curves and generalized additive models, with threshold effects employed to calculate inflection points. Additionally, subgroup analyses and interaction tests were conducted.ResultsThe study included 13,936 individuals with a mean age of 51.19 ± 16.65 years. Fitted smoothed curves and generalized additive models revealed a nonlinear, inverted U-shaped relationship between the two variables. Threshold effect analysis showed a significant negative association between PHR and total femur bone mineral density (BMD) beyond the inflection point of platelet to HDL-C ratio (PHR) 33.301. Subgroup analyses showed that a significant interaction between these two variables was observed only in the age and sex subgroups (P-interaction < 0.05).ConclusionsOur study identified a complex, nonlinear, inverted U-shaped relationship between platelet to HDL-C ratio (PHR) and total femur bone mineral density (BMD). These findings underscore the importance of maintaining optimal PHR levels to support bone health, especially in high-risk populations.

The association between macrosomia and glucose, lipids and hormones levels in maternal and cord serum: a case-control study

BackgroundThe formation of macrosomia is associated with excessive nutrition and/or unable to regulate effectively. This case-control study aims to explore the relationship between macrosomia and glucose, lipids and hormones levels in maternal and cord serum.MethodsIn the case-control study, 78 pairs of mothers and newborns were recruited who received care at one hospital of Hebei, China between 2016 and 2019. According to the birth weight (BW) of newborns, participants were divided into macrosomia group (BW ≥ 4000 g, n = 39) and control group (BW between 2500 g and 3999 g, n = 39). Maternal vein blood and cord vein blood were collected and assayed. All data were compared between the two groups. Unconditional logistics regression analysis was used to test the relationship between macrosomia and glucose, lipids and hormones in maternal and cord serum.ResultsIn maternal and cord serum, the levels of leptin, leptin/adiponectin ratio (LAR), glucose and triglyceride (TG) in macrosomia group were higher than those in control group, and the levels of high-density lipoprotein cholesterol (HDL-C) were lower. The percentage of maternal glucose and lipids transfer to cord blood did not differ between the two groups. High levels of TG in maternal serum were positively correlated with macrosomia, and high levels of LAR, TG and glucose in cord serum were positively correlated with macrosomia.ConclusionIn conclusion, the results of the current study, suggest that the nutrients and metabolism-related hormones in maternal and umbilical cord are closely related to macrosomia. During pregnancy, the nutritional status of pregnant women should be paid attention to and to obtain a good birth outcome.

The therapeutic effect of PCSK9 inhibitors on dyslipidemia: one-year follow up.

Despite the availability of statins and lifestyle modifications, many patients with Dyslipidemia struggle to achieve optimal low-density lipoprotein cholesterol (LDL-C) control. PCSK9 inhibitors offer a promising new therapeutic option with superior LDL-C lowering efficacy compared to statins. However, data on their real-world use, particularly in Iran, is limited. This study aims to address this gap by investigating the one-year effects of evolocumab on lipid profiles and potential cardiovascular outcomes in Iranian patients with Familial Hypercholesterolemia (FH).This single-center, prospective study evaluated evolocumab effectiveness in lowering LDL-C in 50 Iranian adults with FH. Participants with a documented LDL-C > 190 mg/dL on existing cholesterol medications (excluding PCSK9 inhibitors) and a clinical FH diagnosis was included. After baseline assessments (medical history, demographics, lipid profile), evolocumab was administered subcutaneously every two weeks for one year. Follow-up assessments at year one measured changes in LDL-C, high-density lipoprotein cholesterol (HDL-C), and triglycerides. The study enrolled 50 participants with an average age of 55 years old (range 35-80 years).Treatment with evolocumab led to significant improvements in lipid profiles at all follow-up points compared to baseline. On average, LDL-C levels decreased by 105.24 mg/dL, triglycerides decreased by 59.20 mg/dL, and HDL-C levels increased by a modest but significant 4.5 mg/dL after one year(p<0.001). Subgroup analysis revealed no statistically significant interactions between baseline demographics (age, sex, BMI) or lifestyle habits (smoking, alcohol) and changes in lipid levels(p>0.05). However, a significant interaction emerged between baseline lipid levels and their corresponding reductions, suggesting greater improvement in patients with higher baseline values(p<0.05). It is noteworthy that no new cardiovascular events were reported during the study period. This study demonstrates the effectiveness of evolocumab in improving lipid profiles in Iranian patients with FH. The observed reductions in LDL-C and triglycerides, along with a modest increase in HDL-C, suggest potential benefits for cardiovascular risk reduction. The absence of new cardiovascular events during the study is encouraging, but further research with larger and longer-term follow-up is needed to confirm these findings and assess the long-term safety and impact on quality of life.

Levels of serum lipids predict responses to PD-L1 inhibitors as first-line treatment in small cell lung cancer: an observational study.

Immunotherapy provides new hope to individuals with small cell lung cancer (SCLC). Predicting biomarkers for clinical effects is crucial for SCLC patients receiving programed death-ligand 1 (PD-L1) inhibitor treatment. The aim of this study was to clarify the value of serum lipids as predictors of immune related adverse events (irAEs) and the anti-tumour effects in SCLC patients who received PD-L1 inhibitors as first-line treatment. This study included patients with SCLC who received at least one cycle of PD-L1inhibitors at Shanghai Pulmonary Hospital from August 2020 to December 2023. We collected the clinical data of the SCLC patients, including basic information and serum lipid levels, before immunotherapy. The irAEs rate was 16.1% of 124 enrolled patients. In multivariate analysis, the triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C) ratio was an independent predictor of irAEs (p = 0.045). Tumour response analysis indicated that the objective response rate (ORR) was 43.4% and the disease control rate (DCR) was 79.5%. Seventy-seven patients experienced any progression-free survival (PFS) event. The median PFS was longer in the HDL-C-high group (10.03months) than in the HDL-C-low group (6.67months) (p = 0.043). In Cox regression analysis, the serum HDL-C level was an independent predictor of PFS (p = 0.002). For patients of the high TG/HDL-C ratio, the ORR significantly differed between patients who suffered from any irAEs and those who did not (p = 0.0139). This study found that serum lipid levels might predict the responses to anti-PD-L1 as first-line treatment for SCLC.

High-density lipoprotein cholesterol trajectory and new-onset metabolic dysfunction-associated fatty liver disease incidence: a longitudinal study

BackgroundAlthough high-density lipoprotein cholesterol (HDL-C) exerts a significant influence on the development of metabolic dysfunction-associated fatty liver disease (MAFLD), the association of dynamic changes in HDL-C levels with the risk of MAFLD remains unclear. Thus, the aim of the current study was to explore the association between the changing trajectories of HDL-C and new-onset MAFLD. The findings of this study may provide a theoretical basis for future personalized intervention and prevention targeting MAFLD.MethodsA total of 1507 participants who met the inclusion criteria were recruited from a community-based physical examination population in Nanjing, China from 2017 to 2021. Group-based trajectory models were constructed to determine the heterogeneous HDL-C trajectories. The incidence of MAFLD in each group in 2022 was followed up, and the Cox proportional hazards regression model was applied to investigate the associations between different HDL-C trajectories and the risk of new-onset MAFLD.ResultsThe incidences of MAFLD in the low-stable, moderate-stable, moderate-high-stable, and high-stable groups of HDL-C trajectory were 26.5%, 13.8%, 7.2% and 2.6%, respectively. The incidence rate of MAFLD in the order of the above trajectory groups exhibited a decreasing trend (χ2 = 72.55, Ptrend<0.001). After adjusting for confounders, the risk of MAFLD onset in HDL-C low-stable group was still 5.421 times (95%CI: 1.303–22.554, P = 0.020) higher than that in the high-stable group. Subgroup analyses of the combined (moderate high-stable and high-stable groups combined), moderate-stable and low-stable groups showed that sex, age, and overweight/obesity did not affect the association between HDL-C trajectory and MAFLD risk.ConclusionsPersistently low HDL-C level is a risk factor for the onset of MAFLD. Long-term monitoring of HDL-C levels and timely intervention for those experiencing persistent declines are crucial for early prevention of MAFLD.

Relationship between radiation dose and markers of insulin resistance and inflammation in atomic bomb survivors.

In recent studies of childhood cancer survivors, diabetes has been considered a late effect associated with high therapeutic doses of radiation therapy. Our recent study of atomic bomb (A-bomb) survivors also suggested an association between radiation dose and diabetes incidence, with exposure city and age at exposure as radiation dose effect modifiers. Insulin resistance mediated by systemic inflammation and abnormal body composition has been suggested as a possible primary mechanism for the incidence of diabetes after total body irradiation, however, no studies have examined low-to- moderate radiation exposure (<4 Gy) and insulin resistance in A-bomb survivors. To examine the association between radiation dose and markers of inflammation and insulin resistance. This study investigated 3,152 survivors who underwent a health examination between 2008 and 2012 and who were younger than 15 years at exposure. Multivariate linear regression analyses were used to evaluate the radiation effects on levels of markers of inflammation and insulin resistance. Radiation dose was significantly and positively associated with levels of CRP, triglycerides, homeostasis model assessment of β-cell function (HOMA-β), and HOMA of insulin resistance (HOMA-IR) after adjustment for relevant covariates including sex, city, and age at exposure. Adiponectin and HDL cholesterol levels were also associated significantly and negatively with radiation dose. However, city was not a dose modifier of the radiation response on these markers of inflammation and insulin resistance. Insulin resistance might be a possible factor in the radiation related diabetes incidence in the A-bomb survivors.

Effects of Different Caloric Restriction Patterns on Blood Pressure and Other Cardiovascular Risk Factors: A Systematic Review and Network Meta-Analysis of Randomized Trials.

All types of caloric restriction are preventive against cardiovascular risk factors, but the best restriction method and most affected factors have not been identified. The objective of this study was to explore the effects of different caloric restriction methods on various cardiovascular risk factors by horizontally comparing program advantages and disadvantages via network meta-analysis. The PubMed, Web of Science, Cochrane Library, and Embase literature databases were searched (October 2013 to October 2023). Eligible randomized controlled trials involving participants who underwent caloric restriction and systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), and high-density lipoprotein (HDL) cholesterol level measurements were included. Thirty-six of 13 208 records (0.27%) were included. Two researchers reviewed the articles, extracted data, and assessed article quality. Alternate-day fasting (ADF) reduced SBP (4.88 mmHg; CI, 2.06-7.15) and DBP (5.10 mmHg; CI, 2.44-7.76). Time-restricted eating reduced SBP (2.46 mmHg; CI, 0.16-4.76) but not DBP. Continuous energy restriction (CER) significantly reduced BMI (1.11 kg/m2; CI = 0.16, 2.06) and waist circumference (3.28 cm; CI, 0.62-5.94). This meta-analysis confirmed the preventive effect of CER and ADF on various cardiovascular risk factors. Additionally, CER is more likely to reduce obesity, and ADF is more likely to reduce blood pressure (BP). Based on this meta-analysis, CER is recommended to control obesity only for people who are obese and do not have elevated BP or other abnormal indicators. Additionally, ADF for early control or prevention is recommended for patients who have abnormal BP or other cardiovascular risk factors. PROSPERO registration no. CRD42023455889.

Anti-obesity and immunomodulatory effects of Allium hookeri leaves cultivated with artificial light of different intensities on immune-depressed obese mice

This study was conducted to evaluate the effects of Allium hookeri (AH) leaves cultivated with different light-emitting diode (LED) intensities (L: low, 100 μmol/m2/s; M: medium, 150 μmol/m2/s; H: high, 200 μmol/m2/s). Alliin concentration increased as light intensity increased in AH and showed the highest level at LED-H condition. The anti-obesity and immunomodulatory properties of AH were evaluated in a cyclophosphamide (CPA)-induced immunosuppressed obese animal model. C57BL/6 J mice were randomly divided into control (CON), high-fat diet (HFD) control (CON-H), negative control (NC), positive control (PC, β-glucan, 50 mg/kg body weight (BW)), AH L, M, and H groups. The three kinds of AH extracts were orally administered to the mice at 300 mg/kg BW for 2 weeks. Except for CON and CON-H, all the other groups were intraperitoneally treated with CPA. Epididymal and abdominal fat weight decreased as LED intensity increased while spleen weight increased in the AH groups. Serum glucose decreased as LED intensity increased in the AH groups and H group showed the lowest level. Triglycerides, total, and LDL-cholesterol levels decreased while HDL-cholesterol level increased in the AH groups compared to the NC group. Moreover, AH effectively reduced serum ALT and AST levels and increased the total white blood cell count, particularly elevating lymphocyte and monocyte levels. Furthermore, NK cell activity was higher in the AH groups. These findings suggest that AH cultivated at optimal LED intensity could be used as a novel biomedicine and in pharmacotherapy to treat related diseases to improve public health without any toxicity.

A randomized, placebo-controlled trial of purified anthocyanins on cognitive function in individuals at elevated risk for dementia: Analysis of inflammatory biomarkers toward personalized interventions

BackgroundDementia poses a significant global health challenge. Anthocyanins neutralize free radicals, modulate signaling pathways, inhibit pro-inflammatory genes, and suppress cytokine production and may thus have positive cognitive effects in people at increased risk of dementia. We aim to investigate the effects of purified anthocyanins on cognitive function in people at increased risk of dementia according to their inflammation status based on blood-based inflammatory biomarkers. MethodsThis is a secondary analysis of a 24-week randomized, double-blind, placebo-controlled trial. Cluster analysis was performed to categorize two groups based on their individual inflammatory biomarker profile using multiplex sandwich ELISA for the quantitative measurement of cytokines. Descriptive statistics and longitudinal models assessed cognitive outcomes. The primary comparison was the group difference at week 24 based on a modified intention-to-treat analysis. ResultsCluster analysis revealed two distinct inflammatory biomarker profiles. In Cluster 1 (high levels of inflammation biomarkers), anthocyanin treatment showed a statistically significant improvement on cognitive function compared to placebo at 24 weeks. No significant differences were observed in Cluster 2 (low levels of inflammation biomarkers). The demographic characteristics, cognitive scores, and biomarker distributions were similar between treatment groups at baseline. However, cluster 1 exhibited higher BMI, diabetes prevalence, medication usage, and lower HDL cholesterol levels. ConclusionIndividuals with elevated levels of inflammation markers benefited from anthocyanin treatment to enhance cognitive performance, whereas those with lower levels did not. The anti-inflammatory and antioxidant properties of anthocyanins make them a promising intervention, and future prospective trials in people with increased inflammation are warranted.

Effects of chitosan guanidine on blood glucose regulation and gut microbiota in T2DM

Diabetes mellitus (DM) is a chronic metabolic disease characterized by hyperglycemia. Type 2 diabetes mellitus (T2DM) represents approximately 90 % of all DM cases and is primarily caused by an imbalance in blood glucose homeostasis due to inadequate insulin secretion or insulin resistance. This study explores the potential therapeutic effects of chitosan guanidine (CSG) on a T2DM mouse model. The findings reveal that CSG significantly enhances oral glucose tolerance (OGTT) and insulin sensitivity (ITT), reduces fasting blood glucose (FBG) levels, and suppresses the expression of proinflammatory cytokines in T2DM mice. These changes improve insulin resistance and diminish inflammation. Additionally, CSG markedly ameliorates lipid metabolism disorders, lowers total cholesterol (TC) and triglyceride (TG) levels, and inhibits hepatic fat accumulation. 16S rRNA and Spearman correlation analyses indicate that CSG promotes the relative abundance of probiotic genera such as Bacteroidota, Patescibacteria, Actinobacteria, and Cyanobacteria. These bacteria are positively correlated with short-chain fatty acids (SCFAs) and high-density lipoprotein cholesterol (HDLC) levels. Conversely, CSG reduces the relative abundance of pathogenic bacteria, including Proteobacteria and Ralstonia, leading to an improved intestinal microbial community composition in T2DM mice and alleviating T2DM symptoms. These results suggest that CSG holds significant potential as a non-insulin therapeutic agent for diabetes management.

Lipid Profile in Type 2 Diabetes Mellitus Patients with and without Diabetic Retinopathy

Diabetes mellitus (DM) is a group of metabolic diseases characterized by hyperglycemia due to abnormalities in insulin secretion, insulin action, or both. Diabetic retinopathy is the most common microangiopathic complication of DM and one of the leading causes of blindness in the world. Poor lipid profile levels are one of the risk factors for diabetic retinopathy. Objective: To analyze differences in the proportion of lipid profile categories in type 2 DM patients with and without diabetic retinopathy. Methods: This was a hospital-based cross-sectional study with 45 samples. The independent variables assessed were the lipid profile, including LDL, HDL, triglycerides, and total cholesterol levels. The dependent variable assessed was the incidence of diabetic retinopathy. The analysis used were univariate and bivariate (Chi-square and Fisher exact). Results: The prevalence of diabetic retinopathy was 37.8%, consist of 17.8% of NPDR and 20% of PDR. There were significant differences in the proportion of LDL categories (p=0.007) and total cholesterol (p=0.038) in type 2 DM patients with and without diabetic retinopathy, and there were no significant differences in the proportion of HDL categories (p=0.719) and triglycerides (p=1) in type 2 DM patients with and without diabetic retinopathy. Conclusion: There were significant differences in the proportion of LDL categories and total cholesterol in type 2 DM patients with and without diabetic retinopathy.

The effect of the modified Atkins diet and anti-seizure medications on lipid marker levels in adults with epilepsy.

Some anti-seizure medications (ASMs) are known to induce liver enzymes and impact lipid values that include total cholesterol (TC), low density lipoprotein cholesterol (LDL), high density lipoprotein cholesterol (HDL), and triglyceride (TG). In addition, use of ketogenic diet therapies, including the modified Atkins diet (MAD), has also influenced lipids. Here, we explored the combined impact of enzyme inducing ASMs (EIASMs) and MAD on lipid values in adults with epilepsy. Diet-naïve adults with epilepsy who began MAD were divided into three groups based on ASM use: EIASMs, non-EIASMs, and those on no ASMs. Demographic information, epilepsy-specific clinical history, anthropometrics and lipid values were obtained through retrospective chart review at baseline and after a minimum of 12 months of MAD use. Forty-two adults on MAD had baseline and follow up 12-month lipid outcomes. There was a significant increase in median levels of TC, LDL, non-HDL, and HDL after 12 months of MAD use. There was no change in median levels of TG. When separated according to ASM category, adults on non-EIASMs showed significant elevations in TC, HDL, and LDL after 12 months of MAD use. In contrast, adults on EIASMs only showed a significant increase in HDL after 12 months of MAD use. The increase in atherogenic cholesterol levels observed after 12 months of MAD use was most pronounced in adults with epilepsy on non-EIASMs and not observed in adults with epilepsy on EIASMs despite a higher proportion of abnormal cholesterol levels at baseline in those on EIASMs.

Association of non-high-density lipoprotein to high-density lipoprotein ratio (NHHR) with prognosis in cancer survivors: a population-based study in the United States.

Patients with cancer frequently exhibit alterations in serum lipid profiles associated with chemotherapy. It has been reported that lipid distribution in cancer correlates with tumor progression. However, the prognostic value of serum lipid biomarkers in cancer survivors remains a subject of debate. We aim to explore the relationship between non-high-density lipoprotein to high-density lipoprotein ratio (NHHR) and the prognosis of cancer survivors. In this study, we analyzed cancer survivor data from the National Health and Nutrition Examination Survey (NHANES) from 1999-2000 to 2017-2018. The study included prospective cohorts that included total cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C) levels as well as mortality data. Weighted multivariate cox regression models, competing risk models and restricted cubic spline (RCS) models were applied to investigate the association between NHHR and cancer survival. Subgroup and sensitivity analyses were performed to test the robustness of the results. This study involved 4,177 participants, representing about 19.6 million U.S. adults. After adjustment for various factors, the lower NHHR group (≤1.64) had a 31% (HR 1.31; 95% CI [1.11,1.54], p = 0.001) higher risk of death from any cause compared to the higher NHHR group. The link between NHHR and mortality remained stable across most subgroups, with notable interactions for smoking (p = 0.006) and diabetes status (p = 0.046). A J-shaped pattern was observed between NHHR and all-cause mortality, significantly among obesity-related cancer survivors (overall association test p-value = 0.0068, non-linear association test p-value = 0.0016). However, a non-significant negative correlation was observed for cancer-specific mortality (overall association test p-value = 0.48, non-linear association test p-value = 0.66). Considering the competitive risk of heart disease and cancer-specific mortality, there is no difference between the high and low NHHR groups, while the low NHHR group showed an increased risk of non-specific causes of death (p < 0.001). The results of this study suggest that NHHR is an important indicator that is strongly associated with all-cause mortality in cancer survivors, and that this relationship may be influenced by the interaction of diabetes and smoking status. This finding may provide important information for future research and patient management.

Correlation between ratio of fasting blood glucose to high density lipoprotein cholesterol in serum and non-alcoholic fatty liver disease in American adults: a population based analysis.

Based on previous research, elevated fasting blood glucose (FBG) and decreased high-density lipoprotein cholesterol (HDL-C) levels are associated with non-alcoholic fatty liver disease (NAFLD). It is hypothesized that the prevalence of NAFLD may be proportional to the FBG-to-HDL-C ratio (GHR). In this study, 3,842 participants from the National Health and Nutrition Examination Survey (NHANES) (2013-2020) were investigated. Liver steatosis was assessed using vibration-controlled transient elastography (VCTE). NAFLD was defined as controlled attenuation parameter (CAP) ≥288 dB/m. After adjusting for race, gender, age, diabetes, BMI, moderate activities, uric acid, albumin, ALT, GGT, ALP, total bilirubin and creatinine, multiple logistic regression analysis indicated a positive correlation between GHR and the prevalence of NAFLD (OR = 1.22, 95% CI = 1.17-1.28). Additionally, multiple linear regression analysis showed a positive correlation between GHR and the severity of liver steatosis according to CA p-values (β = 4.97, 95% CI: 4.28, 5.66). According to the subgroup analysis, the correlation was stronger in other race, participants at the age <50 years old and those with non-diabetes. In this study, a non-linear relationship and saturation effect between GHR and the prevalence of NAFLD was also revealed, characterized by an inverted L-shaped curve, with an inflection point of 7.443. Finally, the receiver operating characteristic (ROC) analysis suggested that the area under the curve (AUC) of GHR (AUC = 0.731) significantly exceeded that of FBG and HDL-C. Elevated GHR levels are independently associated with the severity of liver steatosis and the increased prevalence of NAFLD in American adults.

Effectiveness of Multifaceted Lifestyle Interventions in Prediabetic Adults: A Field Study in an Urban Slum Population of Pune, India.

Introduction Adults with diabetes have an increased risk of hypertension, heart attack, and stroke than those without diabetes. Diagnosing prediabetes at an early stage can significantly reduce the risk of diabetes through simple interventions such as lifestyle modifications. Lifestyle modifications such as weight loss combined with regular physical exercise and a healthy diet can help delay or prevent the progression of diabetes. This study aims to estimate the prevalence of prediabetesamong the urban slum population and to assess the effect of lifestyle modifications on blood sugar levels, glycated hemoglobin (HbA1c), and lipid profile among the participants. Methods A quasi-experimental field study was conducted among the urban slum population. Participants were randomly selected from previous health screening data. Pre-intervention blood evaluations were performed, and those who fulfilled the criteria were enrolled for interventions. The follow-up period lasted three months and included telephonic and in-person meetings for support and motivation. All variables were reevaluated at the end of the follow-up period. Results Out of 34 participants included in the study, 20 completed the three-month follow-up. Statistically significant changes were observed after three months of intervention in weight, fasting blood sugar, HbA1c, BMI, triglycerides, and high-density lipoprotein (HDL) cholesterol levels. However, decreases in systolic blood pressure (BP), diastolic BP, total cholesterol, and low-density lipoprotein (LDL) cholesterol were not statistically significant. Conclusion The study revealed that lifestyle intervention programs promoting healthy diets, physical activity, and body weight reduction can prevent or delay the onset of diabetes among high-risk populations. The effectiveness of interventions across community settings depends on delivery formats, implementers, and the level of motivation of participants.

Sex differences in the association between chest computed tomography-defined sarcopenia and cardiovascular risk factors among inpatients.

While sarcopenia has been found to be associated with increased risks of cardiovascular diseases (CVDs), evidence exploring sex-related differences remains insufficient. This study aimed to investigate the differences in how often sarcopenia occurs in each sex, as determined by skeletal muscle area (SMA) in chest CT images, and its association with CVD common risk factors. This cross-sectional study involved 1,340 inpatients from the Department of Geriatrics of Renji Hospital, affiliated to Shanghai Jiaotong University School of Medicine. Data on age, sex, body mass index (BMI), smoking status, disease history, and clinical parameters were collected. Sarcopenia was defined using chest CT images with a cut-off value of T12-SMA/height2 <25.75 cm2/m2 in male patients and <20.16 cm2/m2 in female patients. Cardiovascular risk was assessed using the Framingham risk score (FRS). The association between T12-SMA/height2-defined sarcopenia and CVD risk factors by sex was evaluated using a multivariate logistic regression analysis. The overall prevalence of T12-SMA/height2-defined sarcopenia (<25.75 cm2/m2 for male patients, <20.16 cm2/m2 for female patients) was 54.03%, with 48.09% in male patients and 63.19% in female patients. The proportion of male patients with high CVD risk was greater than that of female patients. The multivariate analysis revealed that T12-SMA/height2-defined sarcopenia was independently associated with age (in male patients only), systolic blood pressure (SBP), cholesterol, and high-density lipoprotein cholesterol (HDL-C) among the six FRS cardiovascular risk indices. Our results suggest that T12-SMA/height2-defined sarcopenia was more prevalent in male patients than in female patients. Sarcopenia was associated with higher levels of SBP and HDL-C and lower levels of cholesterol. Increasing age had a more significant effect on CVD risk in male patients.

IMPACT OF DYSLIPIDEMIA ON CORONARY HEART DISEASE IN WOMEN (REVIEW)

Introduction:The increase in the level of lipids in the blood is one of the risk factors for cardiovascular diseases (due to atherosclerosis and thrombosis) increasing premature morbidity, disability, financial cost and mortality, not only in the EU and the USA, but also in countries developing worldwide. It has been proven that lipid disorders promote the development of atherosclerosis and its clinical consequences such as CVD including (coronary heart disease, acute myocardial infarction, peripheral artery disease, heart failure and sudden death). Combinations of lipoprotein levels and lipid fractions play a major risk role in terms of coronary heart diseases. Purpose: Evidence of dyslipidemia as a risk factor for CVD, especially in obese women who suffer from metabolic syndrome or diabetes and have lipid profiles that negatively affect the risk of coronary heart disease. Methodology: International literature review in PubMed, CINAHL, Am J Cardiology, Int J Public Health; in accordance with the purpose and objectives of the study. Result: Coronary heart diseases are the leading cause of death among women and men although they are less common and appear later in women than in men. Each year 345,000 women suffer from an initial or recurrent myocardial infarction, and 261,000 women die from MI. Compared to men, women, and especially women in the postmenopausal period, remain at high risk for coronary disease. In women, calcification occurs 10 to 15 years later. Multiple angiographic studies of coronary arteries have shown a lower rate of epicardial coronary artery disease in women than in age-matched men. Elevated levels of Lp (a) appear to be more associated with the occurrence of coronary heart disease than with the severity of coronary artery disease in both sexes. Outcome data in women using lipid-lowering medications other than statins are extremely limited. Conclusion: The importance of a healthy lifestyle should begin in childhood and continue throughout life. Although the benefits of lipid-lowering therapy in women with cardiovascular disease are clear, more data are needed in those without cardiovascular disease. Clinical trials for lipid-lowering women with cardiovascular disease to date have used a strategy focused on lowering LDL-cholesterol, which may not be optimal for women who have low HDL-cholesterol or triglyceride levels. which are very important factors affecting coronary heart disease. It remains to be determined whether outcomes among women will improve if treatment strategies are directed toward more aggressive and comprehensive modification of lipoprotein profiles.

CRGD-platelet@MnO/MSN@PPARα/LXRα Nanoparticles Improve Atherosclerosis in Rats by Inhibiting Inflammation and Reducing Blood Lipid.

Atherosclerosis (AS) is an inflammatory disease of arterial intima driven by lipids. Liver X receptor alpha (LXRα) and peroxisome proliferator-activated receptor alpha (PPARα) agonists are limited in the treatment of AS due to their off-target effects and serious side effects. Therefore, this study was designed to construct a novel nanoparticle (NP) and evaluate its mechanism of action on inflammation inhibition and lipid reduction in AS. We synthesized cRGD-platelet@MnO/MSN@PPARα/LXRα NPs (cRGD-platelet- NPs) and confirmed their size, safety, and targeting ability through various tests, including dynamic light scattering and immunofluorescence. In vivo and in vitro experiments assessed cell proliferation, apoptosis, inflammation, and plaque formation. Finally, the NF-κB signaling pathway expression in rat aorta was determined using a western blot. The synthesis of cRGD-platelet-NPs was successful; the particle size was approximately 150 nm, and the PDI was below 0.3. They could be successfully absorbed by cells, exhibiting high safety in vivo and in vitro. The cRGD-platelet-NPs successfully reduced plaque formation, improved lipid profiles by lowering LDL-cholesterol, total cholesterol, and triglycerides, and raised HDL-cholesterol levels. Additionally, they decreased inflammatory markers in the serum and aortic tissue, suggesting reduced inflammation. Immunohistochemistry and western blot analyses indicated that these NPs could not only promote M2 macrophage polarization but also suppress the NF-κB signaling pathway. The newly developed cRGD-platelet-NPs with high safety are a promising approach to AS treatment, which can regulate ABCA1, reduce the formation of AS plaques, and enhance cholesterol efflux. The mechanism may involve the suppression of the NF-κB signaling pathway.
