Lower Total Cholesterol Levels Research Articles

Lipid variability in drug-naïve individuals affected with Major Depressive Disorder: a systematic review and meta-analysis

Background This study aimed to provide a comprehensive synthesis of the evidence examining lipid profiles in drug-naïve MDD patients. Materials and methods We searched PubMed, Scopus, and ISI Web of Science up to August 2023 for total cholesterol, HDL-C, LDL-C, and triglyceride levels in drug-naïve MDD patients. Results A total of 17 articles comprising 2174 individuals including drug-naïve MDD subjects and controls were included. Our results showed that concentrations of total cholesterol were lower in drug-naïve MDD patients compared with healthy controls (SMD −0.49, 95% CI −0.881 to −0.105; p = 0.015; I2 = 90.6%). However, comparison of other lipid levels between MDD patients and healthy controls demonstrated no significant difference. The results revealed that the association of total cholesterol levels with MDD is more prominent in male-dominant studies (SMD −1.20, 95% CI −2.23 to −0.18, I2 = 87.9%) than in female-dominant studies (SMD −0.25, 95% CI −0.63–0.13, I2 = 89.0%). In meta-regression, none of the factors including year of publication, Newcastle-Ottawa Scale score, sample size, BMI, and mean age of participants had a significant influence on the association between cholesterol levels and MDD. Conclusions Lower levels of total cholesterol, especially in males, are associated with MDD, so early lipid monitoring and targeted interventions are necessary.

Prevalence and Influence Factors of Cognitive Frailty in the Older Adult Patients Undergoing Maintenance Haemodialysis: A Multi-Centre Cross-Sectional Study.

To examine the prevalence of factors of cognitive frailty in patients undergoing maintenance haemodialysis (MHD). A cross-sectional study. From September 2023 to January 2024, 1023 patients undergoing MHD were recruited from 11 hospitals in Chengdu, China, using convenience sampling. The participants' sociodemographic and lifestyle factors, health information and laboratory indicators were assessed using a general information questionnaire. Cognitive frailty was assessed using the Fried Frailty Phenotype and Montreal Cognitive Assessment Scales. Multivariate logistic regression was used to examine the associations between cognitive frailty and sociodemographic and clinical characteristics. Independent variables for the multivariate logistic regression model encompassing age, sex, educational level, marital status, visual impairment, hearing impairment, falls within a year, depression, weight, height, Malnutrition-inflammation score and serum albumin, sodium, phosphorus, total cholesterol and creatinine levels. Among 1023 participants with a mean age of 69.52 years, 300 (29.3%) had cognitive frailty, with a predominance of older patients. Regression analysis showed that advanced age, low literacy and low serum creatinine, sodium and total cholesterol levels were positively correlated with cognitive frailty. Furthermore, 17.1% of the participants experienced depression, a risk factor for cognitive frailty, and malnutrition was an independent risk factor for cognitive frailty. Older adult patients undergoing (MHD) are at an increased risk of developing cognitive frailty. The aetiology of cognitive frailty in this cohort was multifactorial. Targeted interventions should be designed and implemented based on these factors, prioritising nutritional guidance and mood management to prevent or reverse cognitive frailty. The study adhered to the STROBE checklist. Older adult patients undergoing MHD are at increased risk of developing cognitive frailty. Cognitive frailty screening must be incorporated into the routine assessment of older patients undergoing MHD. No patient or public contribution.

Blood lipid profiles associated with metastatic sites in advanced gastric cancer

BackgroundThis study explored the correlation between peripheral blood lipid levels and clinicopathological parameters in patients with advanced gastric cancer (GC), focusing on changes in lipid levels during disease progression.MethodsPathological features and serum lipid profiles of 179 patients with stage III-IV gastric adenocarcinoma were analyzed. Lipid parameters examined included total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein cholesterol (VLDL-C), apolipoprotein AI (Apo AI), apolipoprotein B (Apo B), lipoprotein(a) (Lp(a)), among others. The total cholesterol-lymphocyte score (TL score) and BMI were also calculated. The association between lipid parameters and clinicopathological characteristics such as age, gender, family history, and metastasis sites was assessed.ResultsIn GC patients, females had higher TG levels than males. Patients with peritoneal metastasis had significantly lower levels of TC, LDL-C, Apo B, and B/A ratio. Those with lung metastasis exhibited higher LDL-C levels and lower levels of VLDL-C. No significant associations were found between lipid levels and metastasis to distant lymph nodes, liver, or bone. Female patients with ovarian metastasis had significantly lower VLDL-C levels. Multivariate analysis revealed low TC as an independent risk factor for peritoneal metastasis, high LDL-C and low VLDL-C levels for lung metastasis, and younger age and low VLDL-C for ovarian metastasis.ConclusionSpecific blood lipid levels are significantly associated with metastatic sites in advanced gastric cancer. Lipid profiles could serve as potential biomarkers for predicting metastatic sites in GC patients.

Exploring the efficacy of al-hijamah (wet cupping) in managing hypertension and dyslipidemia among indonesian population: a meta-analysis

Background: In Indonesia, wet cupping therapy has been thoroughly investigated as a treatment for hypertension and dyslipidemia. Nevertheless, the outcomes across these studies are contradictory. Objectives: To appraise the effectiveness of wet cupping therapy in the management of hypertension and dyslipidemia among the Indonesian population. Methods: We examined papers sourced from Google Scholar, the Indonesian Scientific Journal Database, and Garba Rujukan Digital until September 5, 2020. These papers investigated blood pressure and lipid profile levels both pre- and post-wet cupping treatment. The collective data underwent Z-test analysis to assess associations. Results: In total, we included 26 papers examining the correlation between wet cupping therapy and blood pressure, as well as 16 papers assessing lipid profile levels. Our combined analysis revealed significantly reduced systolic blood pressure (MD: 13.86; 95% CI: 10.01, 17.71), diastolic blood pressure (MD: 6.31; 95% CI: 3.84, 8.79), and lower total cholesterol levels (MD: 21.56; 95% CI: 10.32, 32.80]) in the post-treatment group compared to the pre-treatment group. However, we were unable to elucidate the impact of wet cupping therapy on the concentrations of low-density lipoprotein and triglyceride. Conclusions: Wet cupping therapy exhibits potential efficacy in reducing blood pressure and total cholesterol levels among individuals in Indonesia. Keyword: blood pressure, dyslipidemia, hypertension, lipid profile, wet cupping therapy

Risk factors for intracerebral hemorrhage by five specific bleeding sites: Japan Public Health Center-based Prospective Study.

Evaluating the risk factors for intracerebral hemorrhage is indispensable for primary prevention. However, the pathogenesis varies depending on the bleeding site, and few prospective studies have explored risk factors in detail for each site. The Japan Public Health Center-based Prospective Study is a prospective study comprising a population-based sample of Japanese adults in 1990 (Cohort I) and in 1993 (Cohort II). A total of 34,137 participants (11,907 men and 22,230 women) were enrolled in this study and followed up until 2009 for Cohort I and until 2012 for Cohort II. The association between risk factors (age, sex, blood pressure, serum cholesterol, triglycerides, blood glucose, body mass index, smoking, and drinking status) and intracerebral hemorrhage by its bleeding site (lobes, putamen, thalamus, cerebellum, and brainstem) was assessed using Cox proportional hazards analysis. During a median 20-year follow-up, 571 intracerebral hemorrhage events occurred. Hypertension was associated with an increased risk of total intracerebral hemorrhage, but not lobar hemorrhage. The multivariable hazard ratio (95% confidence intervals) was 2.09 (1.75-2.50) for total intracerebral hemorrhage. In contrast, a low serum total cholesterol level was associated only with lobar hemorrhage (1.73 (1.01-2.96)). Heavy drinking was associated with the risk of total and putamen hemorrhage, and obesity was associated with the risk of putamen hemorrhage. The present study identified different risk factors depending on the bleeding site of intracerebral hemorrhage.

Elevated Plasma Atherogenic and Triglyceride-Glucose Indices: Markers of Cardiovascular Risk in Transfusion-Dependent Thalassemia

Background Transfusion-dependent thalassemia (TDT) is an autosomal recessive disorder characterized by defective hemoglobin synthesis, leading to severe complications such as iron overload and multi-organ dysfunction. This study aims to elucidate the distinctive clinical and biochemical profiles of TDT patients compared to healthy controls, with an emphasis on cardiovascular risk assessment using novel markers such as the Plasma Atherogenic Index (PAI) and Triglyceride-Glucose (TyG) index. Methods This cross-sectional study included 32 TDT patients and 36 healthy controls, matched for age and gender. Comprehensive demographic, laboratory, and imaging data were collected and analyzed. TDT patients were further stratified based on cardiac involvement and ferritin levels. Key assessments included hemoglobin levels, liver enzymes, lipid profiles, and cardiac imaging. The PAI and TyG index were calculated to evaluate cardiovascular risks. Statistical analyses were performed using SPSS 27.0, employing Student’s t-test, Mann–Whitney U test, and Pearson chi-square test as appropriate. Results No significant differences in basic demographic parameters were observed between groups; however, TDT patients exhibited significant clinical and laboratory differences. Notably, these patients had lower hemoglobin levels, higher platelet counts, elevated liver enzymes (ALT and AST), and markedly increased ferritin levels. Lipid profiles were significantly altered, with lower levels of total cholesterol, HDL, and LDL but elevated triglycerides. Importantly, the PAI was significantly higher in TDT patients, suggesting an increased atherosclerotic risk. Subgroup analysis revealed that patients with cardiac involvement had worse metabolic profiles, higher TyG indices, and prolonged QT intervals, indicating heightened cardiovascular risk. As the iron burden increases, the TyG index and PAI may lose their sensitivity in distinguishing between varying levels of iron overload, suggesting that their effectiveness plateaus beyond a certain threshold of iron accumulation. Conclusion TDT patients show significant hematological and metabolic deviations, including elevated cardiovascular risk markers like PAI and TyG index. As iron burden increases, these markers lose discriminative power, and cardiac involvement escalates rapidly once a critical iron threshold is surpassed, as supported by studies showing a non-linear relationship between iron load and cardiac complications. Comprehensive cardiovascular risk assessment and tailored management are essential for these patients. Future studies should focus on tracking cardiovascular risk progression and the effects of targeted interventions.

Impacts of dietary Ajwain (Trachyspermum ammi L.) on growth, antioxidative capacity, immune responses, and intestinal histology of grey mullet (Liza ramada)

This study investigated the impacts of dietary supplements with ajwain seed extract (ASE) on the growth, biochemical parameters, digestive enzymes, antioxidant activity, immunity, and intestine histology of Liza ramada. Juveniles (N = 450) with an initial weight of 40.12 ± 0.14 g were fed six experimental diets enriched with ASE at 0 (control), 0.2, 0.4, 0.6, 0.8, and 1.0 g/kg diet for 60 days. Results revealed that fish-fed diets containing ASE at levels of 0.6 g/kg or higher exhibited significantly improved growth parameters including final weight, weight gain percentage, and specific growth rate, along with enhanced feed conversion efficiency compared to lower ASE levels and the control diet. Survival rates remained similar across all experimental groups. Digestive enzyme activity, particularly lipase, was highest in groups fed higher ASE levels (≥ 0.4 g/kg diet). Histomorphological analysis of the intestine showed improved villi structures with increasing ASE supplementation, reaching an optimal appearance at 0.8 g/kg. Blood biochemical analysis indicated higher total protein and globulin concentrations, and lower total cholesterol levels in groups with higher ASE intake (≥ 0.4 g/kg diet). Immune parameters increased with increasing ASE concentrations, including lysozyme activity, bactericidal percentage, and nitroblue tetrazolium levels. Antioxidant status, measured through superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and malondialdehyde (MDA) levels, showed significant improvements with ASE supplementation, with optimal dietary ASE levels for maximizing SOD (0.73 g/kg), CAT (0.74 g/kg), GPx (0.83 g/kg), and minimizing MDA (0.73 g/kg) identified through polynomial regression analysis. These findings suggest that ASE supplementation (0.6–0.8 g/kg) positively influences the growth performance, digestive function, gut health, immunity, and antioxidant status of L. ramada, highlighting its potential as a beneficial dietary additive in aquaculture.

The Relationship Between Glycemic Control And Lipid Profile In Patients With Type 2 Diabetes Mellitus In Bangli Hospital

Type 2 diabetes mellitus (DM) is prone to diabetic dyslipidemia which is one of the factors in increasing the risk of cardiovascular disease complications. The purpose of this study was to determine the relationship between glycemic control and lipid profile in patients with type 2 DM. Research with a cross-sectional study was conducted at the Internal Medicine Polyclinic of Bangli Hospital in the period January 2023-December 2023 and as many as 60 patients with type 2 DM who met the inclusion criteria. Patients were grouped into type 2 DM patients with controlled glycemic control (HbA1c <7%) and uncontrolled (HbA1c ≥7%). Lower levels of total cholesterol (160,444 ± 30,608 mg/dl vs 203,476 ± 45,471 mg/dl; p = 0.001), triglycerides (125,500 ± 56,019 vs 202,047 ± 91,568; p = 0.002), low-density lipoprotein (K-LDL) (93,072 ± 28,443 vs 131,571 ± 44,590; p = 0.001) in type 2 DM patients with controlled glycemic control. High-density lipoprotein (K-HDL) levels (50,022 ± 14,050 vs 41,152 ± 12,619; p = 0.019) were higher in type 2 DM patients with controlled glycemic control. Statistical tests showed a positive correlation between total cholesterol (r = 0.277; p = 0.032), triglyceride (r = 0.386; p = 0.002) and K-LDL (r = 0.357; p = 0.005) levels with HbA1c levels. There was a negative correlation between K-HDL (r=-0.366; p=0.004) and HbA1c levels. The significant correlation between HbA1c and lipid profile shows the importance of glycemic control in type 2 DM patients. This can be explained in the pathogenesis of type 2 DM during the advanced phase. There was a positive correlation between glycemic control (HbA1c) with total cholesterol, triglycerides and K-LDL. There is a negative correlation between glycemic control (HbA1c) and K-HDL.

In vivo glycerol metabolism in patients with glycerol kinase deficiency.

Glycerol kinase deficiency (GKD) is an X-linked recessive disorder due to glycerol kinase (GK) gene mutations resulting in hyperglycerolermia, hyperglyceroluria, and "pseudohypertriglyceridemia." In vivo glycerol metabolism has not been assessed in GKD. A 62-year-old man with suspected GKD and his extended family underwent whole exome sequencing and fasting blood work with two modes of lipid measurements: (1) standard lipase-based methodology and (2) nuclear magnetic resonance (NMR). Two overnight fasted men with GKD and a heterozygote female carrier then underwent 13C3-glycerol infusion. Affected family members had a novel two-nucleotide deletion in exon 5 of the GK gene (c.373_374del). Compared to their family members (n = 14), men with GKD (n = 5) had significantly lower total cholesterol levels (3.72 ± 0.70 vs. 4.77 ± 0.85 mmol/L, p = 0.024). Compared to NMR, lipase-based assays overreported triglycerides (5.28 ± 1.38 vs. 0.81 ± 0.32, mmol/L, p < 0.001) and underreported low-density lipoprotein cholesterol values (0.93 ± 0.23 vs. 2.18 ± 0.42 mmol/L, p = 0.001) in GKD. Men with GKD could not convert glycerol into glucose or triglycerides, which was preserved in the heterozygote carrier. Glycolytic metabolism of glycerol to lactate persisted in GKD, but it was reduced by a magnitude and, possibly, due to homologous glycerol kinases encoded by other genes. In summary, we report a novel GK pathogenic variant; affected men cannot convert circulating glycerol to glucose or triglycerides and have lower cholesterol levels. These results offer a human model for potentially targeting glycerol kinase to treat conditions associated with hyperglycemia and hyperlipidemia and warrant further investigation.

Prognostic risk factors for pyogenic liver abscess caused by Klebsiella pneumoniae

BackgroundPyogenic liver abscess (PLA) caused by Klebsiella pneumoniae can vary in severity, and several risk factors for the development of organ dysfunction in PLA have been implicated. However, few studies to date have explored the most common risk factors for clinical severity.MethodsWe conducted a study on patients with PLA caused by Klebsiella pneumoniae between February 2013 and December 2022.Using logistic regression analysis, we sought to identify factors associated with positive blood culture, septic shock, and intensive care unit (ICU) admission.ResultsAfter included 200 patients, we found that an elevated procalcitonin (PCT) level (p = 0.03), higher glucose level (p = 0.03), and lower total cholesterol (TC) level (p = 0.01) were associated with a higher likelihood of positive blood bacteriological culture. Additionally, an increased PCT level (p = 0.02) and lower TC level (p < 0.01) were associated with an elevated risk of septic shock. Furthermore, a higher PCT level (p < 0.01) was associated with a higher probability of ICU admission.ConclusionIn patients with PLA caused by Klebsiella pneumoniae, the PCT, glucose, and TC levels were found to be associated with positive blood culture, septic shock, and ICU admission.

Lipoprotein, Cholesterol, Treatment Strategies, and its Impact on Cardiovascular Diseases

A main cause of death internationally, cardiovascular (CV) illness accounted for about 31.4% of fatalities worldwide in 2012. According to estimates, a 33% decline in coronary heart disease (CHD) mortality in the United States between 1980 and 2000 was caused by a decrease in total cholesterol levels. Similar declines in CHD fatalities (varying from 19% to 46%) in other wealthy nations have been linked to lower total cholesterol levels. Lipoproteins are complex particles with a central core containing cholesterol esters and triglycerides surrounded by free cholesterol, phospholipids, and apolipoproteins, which facilitate lipoprotein formation and function. However, numerous individuals do not achieve LDL-C goal values because of statin resistance or adherence to statin medication. If cholesterol targets are not achieved with statins alone, alternative medicines include ezetimibe, fibrates, and nicotinic acid. In addition, people with familial high cholesterol levels (FH). Lipoprotein may act as a proinflammatory mediator that augments the lesion formation in atherosclerotic plaques. HDL metabolism represents a major target for the development of therapies intended to reduce the risk of atherosclerotic cardiovascular disease. Individual cardiovascular preventative treatments should be targeted largely at individuals at higher risk who will benefit most, with the prevention and treatment of dyslipidemia being viewed as a crucial component of those interventions. Since statins have been demonstrated to lessen the risk of serious vascular events by lowering low-density lipoprotein cholesterol (LDL-C), they continue to be the first-choice medication.

The Relationship Between Glycemic Control And Lipid Profile In Patients With Type 2 Diabetes Mellitus In Bangli Hospital

Diabetes Mellitus (DM) type 2 is susceptible to diabetic dyslipidemia, which is one of the factors in increasing the risk of complications from cardiovascular disease. The aim of this study was to determine the relationship between glycemic control and lipid profile in type 2 DM patients. A cross-sectional study was conducted at the Internal Medicine Polyclinic at Bangli Regional Hospital for the period January 2023-December 2023 and a total of 60 type 2 DM patients met the inclusion criteria. Patients were grouped into type 2 DM patients with controlled glycemic control (HbA1c &lt; 7%) and uncontrolled (HbA1c≥7%). Lower levels of total cholesterol (160,444 ± 30,608 mg/dl vs 203,476 ± 45,471 mg/dl; p= 0.001), triglycerides (125,500 ± 56,019 vs 202,047 ± 91,568; p= 0.002), low-density lipoprotein (K-LDL ) (93,072 ± 28,443 vs 131,571 ± 44,590; p= 0.001) in type 2 DM patients with good glycemic control. High-density lipoprotein (K-HDL) levels (50,022 ± 14,050 vs 41,152 ± 12,619; p = 0.019) were higher in type 2 DM patients with good glycemic control. From statistical tests, a positive correlation was found between total cholesterol levels (r = 0.277; p = 0.032), triglycerides (r = 0.386; p = 0.002) and K-LDL (r = 0.357; p = 0.005) with HbA1c levels. There is a negative correlation between K-HDL (r=-0.366; p = 0.004) and HbA1c levels. The significant correlation between HbA1c and lipid profile shows the importance of glycemic control in type 2 DM patients. This can be explained in the pathogenesis of type 2 DM in the advanced phase. There is a positive correlation between glycemic control (HbA1c) and total cholesterol, triglycerides and K-LDL. There is a negative correlation between glycemic control (HbA1c) and K-HDL.

Lipidomic and metabolomic changes in community-acquired and COVID-19 pneumonia

This prospective observational study compared the 1H NMR blood lipidomes and metabolomes of 71 patients with community-acquired pneumonia (CAP), 75 patients with COVID-19 pneumonia, and 75 healthy controls (matched by age and sex) to identify potential biomarkers and pathways associated with respiratory infections. Both pneumonia groups had comparable severity indices, including mortality, invasive mechanical ventilation, and intensive care unit admission rates. Patients with COVID-19 pneumonia exhibited more pronounced hypolipidemia, with significantly lower levels of total cholesterol and LDL-c compared to patients with CAP. Atherogenic lipoprotein subclasses (VLDL-cholesterol, IDL-cholesterol, IDL-triglyceride, and LDL-triglyceride/LDL-cholesterol) were significantly increased in severe cases of both pneumonia types, while lower HDL-c and small, dense HDL particles were associated with more severe illness. Both infected groups showed decreased esterified cholesterol and increased triglycerides, along with reduced phosphatidylcholine, lysophosphatidylcholine, PUFA, omega-3 fatty acids, and DHA. Additionally, infected patients had elevated levels of glucose, lactate, 3-hydroxybutyrate, and acetone, which are linked to inflammation, hypoxemia, and sepsis. Increased levels of branched-chain amino acids, alanine, glycine, and creatine, which are involved in energy metabolism and protein catabolism, were also observed. Neurotransmitter synthesis metabolites like histidine and glutamate were higher in infected patients, especially those with COVID-19. Notably, severe infections showed a significant decrease in glutamine, essential for lymphocyte and macrophage energy. The severity of COVID-19 pneumonia was also associated with elevated glycoprotein levels (glycoprotein A, glycoprotein B, and glycoprotein F), indicating an inflammatory state. These findings suggest that metabolomic and lipidomic changes in pneumonia are connected to bioenergetic pathways regulating the immune response.

Effect of Red Dragon Fruit Extract (Hylocereus polyrhizus) on Total Cholesterol Levels in Wistar Rats Model of Metabolic Syndrome

&lt;p&gt;&lt;strong&gt;Introduction: &lt;/strong&gt;The consumption of high fat and sugar can increase the risk of metabolic syndrome. &lt;em&gt;Hylocereus polyrhizus&lt;/em&gt; is known to be able to lower total cholesterol levels in the blood. This study aims to determine the effect of &lt;em&gt;Hylocereus polyrhizus&lt;/em&gt; extract on total cholesterol levels in Wistar rats with the metabolic syndrome model.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This study used laboratory experimental research using a pretest and posttest with a control group design. The sample consisted of 30 Wistar rats according to the inclusion criteria which were divided into 5 groups: K1 (positive control), K2 (negative control), K3, K4, and K5 (treatment group). The treatment group was given &lt;em&gt;Hylocereus polyrhizus&lt;/em&gt; extract with doses of 60, 120, and 180 mg/200grW. Total cholesterol levels were measured on the 8th, 36th, and 64th day. The data were analyzed using the parameterized One-way ANOVA test followed by Tukey's HSD posthoc test, paired T-test, and Pearson's correlation test.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The average total cholesterol after being given by &lt;em&gt;Hylocereus polyrhizus&lt;/em&gt; extract in K3 (137 ± 2.82 mg/dL), K4 (109 ± 2.31 mg/dL), and K5 (100 ± 2.38 mg/dL) was lower than the negative control group. Data analysis showed significant differences (p&amp;lt;0.05) in total cholesterol levels before and after treatment in all groups. The Pearson correlation test explained that the variation dosage of &lt;em&gt;Hylocereus polyrhizus&lt;/em&gt; extract had a very strong correlation with a positive correlation with total cholesterol levels.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;Induction of &lt;em&gt;Hylocereus polyrhizus&lt;/em&gt; extract at doses of 60, 120, and 180 mg/200grW was able to significantly reduce total cholesterol levels.&lt;/p&gt;

Comparative Analysis of Grape Seed Oil, Linseed Oil, and a Blend: In Vivo Effects of Supplementation.

Grape seeds are rich in bioactive substances, including polyphenols, terpenoids, and phytosterols. Linseed (Linum usitatissimum L.) boasts a high concentration of polyunsaturated fatty acids (PUFAs), lignans, phytoestrogens, and soluble fibers, all contributing to its therapeutic potential. In this study, we pioneered the formulation of an oil blend (GL) combining grape seed oil (G) and golden linseed oil (GL) in equal volumes (1:1 (v/v)) and we evaluated in terms of the nutritional, physical, and chemical properties and their influence in an in vivo experimental model. We analyzed the oils by performing physical-chemical analyses, examining the oxidative stability using Rancimat; conducting thermal analyses via thermogravimetry/derivative thermogravimetry (TG/DTG) and differential scanning calorimetry (DSC), performing optical UV-vis absorption analyses; examining the fluorescence emission-excitation matrix, total carotenoids, and color, and conducting metabolic assessments in an in vivo experimental trial. The fatty acid profile presented a higher fraction of linoleic acid (C18:2) in G and GL and alpha-linolenic acid (C18:3) in L. The acidity and peroxide indices were within the recommended ranges. The TG/DTG, DSC, and Rancimat analyses revealed similar behaviors, and the optical analyses revealed color variations caused by carotenoid contents in L and GL. In the in vivo trial, G (G2: 2000 mg/kg/day) promoted lower total consumption, and the blend (GL: 2000 mg/kg/day) group exhibited less weight gain per gram of consumed food. The group with G supplementation (G2: 2000 mg/kg/day) and GL had the highest levels of HDL-c. The group with L supplementation (L2: 2000 mg/kg/day) had the lowest total cholesterol level. The L2, G1 (1000 mg/kg/day), and G2 groups exhibited the lowest MCP-1 and TNF-α values. Additionally, the lowest adipocyte areas occurred in G and GL. Our results suggest that this combination is of high quality for consumption and can influence lipid profiles, markers of inflammation, and antioxidant status.

Examining the relationship between alterations in plasma cholesterol, vascular endothelin-1 levels, and the severity of sepsis in children: An observational study.

Considering the significant impact of total cholesterol (TC) and vascular endothelin-1 (ET-1) on children sepsis outcomes, this research aimed to explore the association between the levels of plasma cholesterol and vascular endothelin-1 and the severity of sepsis and evaluated its clinical implications. In this study, we examined 250 pediatric patients diagnosed with sepsis between February 2019 and April 2021, collecting data on their plasma levels of TC and ET-1. Depending on the observed outcomes, the participants were divided into 2 categories: a group with a positive prognosis (control group, n = 100) and a group with a negative prognosis (n = 50). We assessed the significance of plasma TC and ET-1 levels in forecasting the outcomes for these pediatric patients. Patients in the group with a poor prognosis experienced notably longer hospital stays and higher treatment expenses than those in the control group (P < .05). Within the first 24 hours of admission and again on days 3 and 7, the levels of ET-1 were significantly higher in the poor prognosis group, whereas plasma TC levels were notably lower in comparison to the control group (P < .05). A Spearman correlation analysis identified a significant correlation between the levels of plasma TC and ET-1 and the severity of sepsis among the children (P < .05). The diagnostic performance for the severity of sepsis in children, as measured by the area under the curve (AUC), was 0.805 for plasma TC, 0.777 for ET-1 levels, and 0.938 when both were combined. This investigation underscores a meaningful relationship between the levels of plasma TC and ET-1 in pediatric sepsis patients, suggesting these biomarkers are highly valuable in predicting patient outcomes. High levels of ET-1 and low levels of TC in these patients signify a grave condition and a poor prognosis.

Investigating the Cardio-protective Activity of Agaricus bisporus in Wistar Rats Induced with Myocardial Infarction

Myocardial infarction is now recognized as one of the chronic diseases and the leading cause of death across the globe. The use of plants abundant in our environment, especially Agaricus bisporusprovides a cheap alternative to combat this common foe of mankind. Hence, this study was carried out to evaluate the cardio-protective effect of the leaf extract of Agaricus bisporus in isoproterenol-induced myocardial infarction. Fresh sample of Agaricus bisporus were purchased from a market at Asaba, Delta State, Nigeria. The samples were thereafter shredded with a knife and oven-dried at 40oC and pulverized and extracted, using Solvent-solvent (ethanol and water) (7:3) via maceration for 72 hr. The filtrate was evaporated to dryness to obtain the ethanol extract which was used for further bioassay study. The animals were administered with the extract of A. bisporus orally for fourteen consecutive days at a divided dose of 100 mg/kg, 200 mg/kg and 400 mg/kg body weights and thereafter 0.2 ml isoproterenol (ISO) at 150 mg/kg was injected intraperitoneally at an interval of 24 h on the 15th and 16th day. Subsequently, the blood pressures were monitored and blood collected for bioassay studies. Assay of High density lipoprotein cholesterol (HDL-c), low density lipoprotein cholesterol (LDL-c), triglyceride (TG) and total cholesterol (TC) levels as well as activities of lactate dehydrogenase (LDH), were carried out with standard assay kit sourced from Randox laboratories Ltd, United Kingdom with maximum adherence to the manufacturer’s instruction. Results showed a significant increase (P&lt;0.05) in high density lipoproteins (HDL) levels and lactate dehydrogenase (LDH) activities with a significant decrease (P&gt;0.05) in low density lipoproteins (LDL) and triglyceride levels in a dose-dependent manner (100&lt;200&lt;400 mg/kg body weight) among the extract treated groups when compared to the untreated control group. Conversely, total cholesterol levels of extract treated groups showed no significant difference when compared with the untreated control group.The findings of this work have shown that extract of Agaricus bisporus could help to mitigate cardiovascular diseases and could be used to produce plant based products to combat myocardial infarction, thereby improving general wellbeing.

Serum cholesterol levels are inversely associated with the risk of malignancy in subjects with Bethesda category IV thyroid nodules

IntroductionSome epidemiological data suggest that there may be an inverse relationship between cholesterol levels and the risk of thyroid cancer in the overall population. The present study was aimed to evaluate the lipid profile specifically in subjects with Bethesda category IV thyroid nodules, and compare whether there were any differences between those with benign and malignant nodules. MethodsSingle-centre, retrospective study on 204 subjects treated by partial or total thyroidectomy for excision of a Bethesda category IV thyroid nodule, who had undergone a blood lipid profile test in the 12 months prior to surgery. In addition to lipid measures, other demographic, clinical, biochemical and ultrasound data were collected. ResultsSeventy-five subjects (36.8%) were diagnosed with thyroid carcinoma in the definitive histopathological examination. Patients with thyroid cancer had lower levels of total cholesterol, LDL-cholesterol and non-HDL-cholesterol than subjects with benign thyroid diseases. There were no differences in HDL-cholesterol, triglycerides or total cholesterol/HDL-cholesterol ratio. There were no differences either between groups in other clinical, biochemical and ultrasound variables, including the use of lipid-lowering drugs. In multivariate analysis, only LDL-cholesterol was independently associated with malignancy. Subjects with follicular carcinoma showed the lowest cholesterol levels, while those with papillary carcinoma had intermediate values between the group with follicular carcinoma and the group with benign thyroid diseases. ConclusionsIn subjects with cytologically indeterminate Bethesda category IV thyroid nodules, levels of total cholesterol, non-HDL-cholesterol and, particularly, LDL-cholesterol are lower among those with malignant nodules.

Lipid Profiles and Atrial Fibrillation in Ischemic Stroke Patients Treated with Thrombectomy: Experience from a Tertiary Italian Stroke Hospital.

To assess acute lipid profiles, atrial fibrillation and other cardiovascular risk factors in patients undergoing treatments by thrombectomy (EVT) with acute ischemic stroke (AIS). We performed a retrospective analysis of the lipid profile and vascular risk factor in 1639 consecutive patients with acute ischemic stroke between January 2016 and December 2021. To assess lipid profiles, laboratory tests, including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG), were obtained the day after admission. We also examined the association between lipid profile, AF and EVT in multivariate logistic regression analysis. Median age of patients was 74 years, 54.9% were males (95% CI 52.5-57.4%), and 26.8% (95% CI, 24.7-29.0%) had AF. EVT patients (n = 370; 22.57 %; 95% CI, 20.6-24.7) showed no difference in age (median 73 years (IQR; 63-80) versus 74 years (IQR; 63-82)), HbA1c levels (median 5.8 (IQR; 5.4-6.2) versus 5.9 (IQR; 5.4-6.4)), TG/HDL ratio (median 2.40 (IQR; 1.65-3.48) versus 2.51 (IQR; 1.73-3.64)), diabetes (OR 0.82; 95% CI 0.61 to 1.08), hypertension (OR 0.87; 95% CI 0.68 to 1.12) and obesity (OR 1.06; 95% CI 0.78 to 1.42) compared to non-EVT patients. Conversely, EVT patients showed lower levels of TC (160 mg/dl (IQR; 139- 187) versus 173 mg/dl (IQR; 148-202); p <0.001), LDL-C (105 mg/dl (IQR; 80-133) versus 113 mg/dl (IQR; 88-142); p <0.01), TG (98 mg/dl (IQR; 76-126) versus 107 mg/dl (IQR; 85-139); p <0.001), non-HDL-C (117 mg/dl (IQR; 94-145) versus 127 mg/dl (IQR; 103-154); p <0.001), HC (8.3 mmol/l (IQR; 6-11) versus 10 mmol/l (IQR; 7.3-13.5); p <0.001) than non-EVT patients. Multivariate logistic regression analysis showed an independent association of EVT with TC (OR 0.99, 95% CI 0.98-0.99), AF (OR 1.79, 95% CI 1.34-2.38), age (OR 0.98, 95% CI 0.96-0.99), and NIHSS (OR 1.17, 95% CI 0.14-1.19). Total cholesterol and all cholesterol-related measures were significantly lower in patients undergoing thrombectomy than in other stroke patients. Conversely, we found that AF was significantly high in patients with EVT, suggesting that hypercholesterolemia could be mainly linked to small-vessel occlusion stroke while large vessel occlusion (LVO) stroke could show different causes. AIS patients may have different pathogenesis and their understanding may improve the discovery of specific and tailored preventive treatments.

PCSK9 inhibitors ameliorate arterial stiffness in ACS patients: evidences from Mendelian randomization, a retrospective study and basic experiments.

Current evidences suggest that Proprotein Convertase Subtilisin/kexin Type 9 inhibitors (PCSK9i) exhibit a protective influence on acute coronary syndrome (ACS). Nevertheless, further investigation is required to comprehend the impact and mechanisms of these pharmaceutical agents on inflammatory factors and arterial stiffness (AS) in patients with ACS. Consequently, the objective of this study is to ascertain the influence of PCSK9i on arterial stiffness in ACS patients and elucidate the underlying mechanisms behind their actions. This study employed Mendelian randomization (MR) analysis to examine the association between genetic prediction of PCSK9 inhibition and arterial stiffness. Data of 71 patients with ACS were retrospectively collected, including PCSK9i group (n = 36, PCSK9 inhibitors combined with statins) and control group (n = 35, statins only). Blood lipid levels, inflammatory markers and pulse wave velocity (PWV) data were collected before treatment and at 1 and 6 months after treatment for analysis. Additionally, cell experiments were conducted to investigate the impact of PCSK9i on osteogenesis of vascular smooth muscle cells (VSMCs), utilizing western blot (WB), enzyme-linked immunosorbent assay (ELISA), and calcification index measurements. The results of the MR analysis suggest that genetic prediction of PCSK9 inhibition has potential to reduce the PWV. Following treatment of statins combined with PCSK9 inhibitors for 1 and 6 months, the PCSK9i group exhibited significantly lower levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), C-reactive protein (CRP), interleukin-6 (IL-6), fibrinogen (FIB) and procalcitonin (PCT) compared to the control group (p < 0.05). Additionally, PWV in the PCSK9i group demonstrated significant reduction after 6 months of treatment and was found to be associated with the circulating CRP level. In cell experiments, PCSK9i pretreatment ameliorated osteogenesis of VSMCs through reducing the deposition of calcium ions, alkaline phosphatase (ALP) activity, and expression of runt-related transcription factor 2 (RUNX2). PCSK9i have potential to enhance arterial stiffness in ACS patients. Specifically, at the clinical level, this impact may be attributed to alterations in circulating CRP levels. At the cellular level, it is associated with the signaling pathway linked to RUNX2.
