Cholesterol Levels Research Articles

Isolation and assessment of probiotic potential of Acidipropionibacterium acidipropionici C03B-STR from goat milk with cholesterol-lowering capability.

Elevated levels of cholesterol or triglycerides in the blood are one of the major risk factors for coronary heart disease, which is the foremost leading cause of death across the world. The aims of this study were to isolate and verify the potential probiotic strain and cholesterol-lowering capability from goat milk. The C03B-STR isolate had a broad-spectrum antibacterial property and exhibited remarkable bacteriostatic activity against Klebsiella pneumoniae ATCC 13883 (27.00 ± 1.73mm), Pseudomonas aeruginosa ATCC 27853 (19.33 ± 0.57mm) and Staphylococcus aureus ATCC 10832 (19.00 ± 1.00mm) by agar well diffusion assay. This isolate is closely related to the 16S rDNA sequence of Acidipropionibacterium acidipropionici. Acidipropionibacterium acidipropionici C03B-STR can survive under acidic conditions (60.51 ± 0.02% of survival rate at pH 3.0 for 3h) and was as bile-tolerant strain (> 80% of survival rate at 0.30% bile salts after 3h of incubation). Furthermore, it showed significantly high cell surface hydrophobicity (74.36 ± 0.23%) and aggregation capability (> 83%) (p ≤ 0.05) but displayed low to moderate co-aggregation ability (44-61%). This strain can also be regarded as strongly adhesive (73.69 ± 0.74%) and inhibit pathogen attachment to the Caco-2 cell lines (39.20 ± 0.59-69.01 ± 0.29%). A. acidipropionici C03B-STR appeared to be safe (non-haemolytic) and controllable (sensitive to various antibiotics). Notably, it had the potential to suppress cholesterol uptake in Caco-2 cells (approximately 45%) and also reduced cholesterol level above 84% during the exponential phase under acidic conditions. Thus, A. acidipropionici C03B-STR from goat milk may be a promising novel potential cholesterol-lowering probiotic strain for application in functional foods and biotherapeutics.

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.

Targeted NGS Revealed Pathogenic Mutation in a 13-Year-Old Patient with Homozygous Familial Hypercholesterolemia: A Case Report

Familial hypercholesterolemia is an autosomal hereditary disease defined by an increased level of low-density lipoprotein cholesterol (LDL-C), which predisposes significant risks for premature cardiovascular disorders. We present a family trio study: proband, a 13-year-old Kazakh girl with homozygous familial hypercholesterolemia (HoFH) and her parents. HoFH is much more rare and severe than a heterozygous form of the disorder. HoFH patients generally present with LDL-C levels exceeding 13 mmol/L, resulting in early and life-threatening cardiovascular events within the first decades of life. In cases of neglected treatment, young patients have a risk of death from coronary diseases before the age of 30. The aim of this research was to identify genetic mutations in the affected patient and her parents. Genetic testing was necessary due to highly elevated LDL-C levels and the presence of multiple xanthomas. Targeted next-generation sequencing (NGS) was performed in this study using the Illumina TruSight cardio panel, which targets 174 genes related to cardiac disorders. The girl was diagnosed with HoFH based on the results of genetic testing. A biallelic mutation was observed in exon 3 of the low-density lipoprotein receptor (LDLR): c. 295 G>A (p.Glu99Lys). Sanger sequencing confirmed that the mutant gene was inherited from both parents. After confirming the genetic diagnosis of HoFH, the patient was treated with LDL apheresis and statins. This case report is the first study of HoFH in a pediatric patient from the Central Asian region. Globally, it emphasizes the need for increased clinical awareness among healthcare providers, as early detection and intervention are important for improving outcomes, particularly in pediatric patients with this rare genetic disorder.

BMI trajectories from birth to young adulthood associate with distinct cardiometabolic profiles.

Numerous studies have investigated links between body mass index (BMI) trajectories and cardiovascular risk, yet discrepancies in BMI measurement duration and timing of the cardiovascular-related outcome evaluation have led to inconsistent findings. We included participants from the Swedish birth cohort (BAMSE) and applied latent class mixture modeling to identify BMI trajectories using data of multiple BMI measures (≥ 4 times) from birth until 24-year follow-up (n = 3204). Subsequently, we analyzed the associations of BMI trajectories with lipids (n = 1974), blood pressure (n = 2022), HbA1c (n = 941), and blood leukocytes (n = 1973) using linear regression. We also investigated the circulating levels of 92 inflammation-related proteins (n = 1866) across BMI trajectories. Six distinct BMI groups were identified, denoted as increasing-persistent high (n = 74; 2.3%), high-accelerated increasing (n = 209; 6.5%), increasing-accelerated resolving (n = 142; 4.4%), normal-above normal (n = 721; 22.5%), stable normal (n = 1608; 50.2%), and decreasing-persistent low (n = 450; 14.1%) BMI groups. The increasing-persistent high and high-accelerated increasing BMI groups had higher levels of total cholesterol [mean difference (95% confidence intervals): 0.30 (0.04-0.56) and 0.16 (0.02-0.31) mmol/L], triglyceride, low-density lipoprotein, hemoglobin A1C [3.61 (2.17-5.54) and 1.18 (0.40-1.98) mmol/mol], and low-density lipoprotein/high-density lipoprotein ratios, but a lower level of high-density lipoprotein than the stable normal BMI group. These two groups also had higher leukocyte cell counts and higher circulating levels of 28 inflammation-related proteins. No increased cardiometabolic markers were observed in the increasing-accelerated resolving BMI group. Participants with persistently high or accelerated increasing BMI trajectories from birth to young adulthood have elevated levels of cardiometabolic risk markers at young adulthood than those with stable normal BMI. However, a raised BMI in childhood may not be inherently harmful to cardiometabolic health, provided it does not persist into adulthood.

Association between the oxidative balance score with metabolic syndrome traits in US adults

ObjectiveTo explore the association between the Oxidative Balance Score (OBS), which represents the balance of multiple oxidative stress-related dietary and lifestyle exposures, and the risk of metabolic syndrome (MetS).MethodsA population-based cross-sectional study design was adopted and 16,850 participants in NHANES database were included in the statistics analysis stage. The OBS was constructed by combining information from 20 a priori selected pro- and antioxidant factors. Weighted logistic regression and restricted cubic splines (RCS) were used to estimate the association between OBS and MetS.ResultsParticipants in the highest OBS quartile, indicating low oxidative stress (OS) levels, exhibited a significantly lower risk of MetS (odds Ratio [OR] = 0.55, 95% confidence Interval [CI]: 0.47–0.64) compared to the lowest quartile. Specifically, higher OBS was inversely associated with abdominal obesity (OR = 0.61, 95% CI: 0.54–0.69), hypertension (OR = 0.69, 95% CI: 0.58–0.83), elevated triglycerides (OR = 0.68, 95% CI: 0.57–0.82), low high-density lipoprotein cholesterol (HDL-C) levels (OR = 0.60, 95% CI: 0.50–0.70) and fasting blood glucose (FBG) levels (OR = 0.74, 95% CI: 0.62–0.88). The observed inverse association between OBS and hypertension or FBG levels appeared to primarily influenced by BMI. The association between dietary OBS intervals and elevated FBG levels was not statistically significant in men, whereas the risk was lower by 25% in women.ConclusionsA higher OBS, representing a balance of multiple oxidative stress-related dietary and lifestyle exposures, is associated with a lower risk of MetS. Therefore, adhering to an antioxidant diet and lifestyle may help prevent the occurrence of metabolic disorders.

Dynamic trajectories of left ventricular ejection fraction in heart failure with improved ejection fraction.

Heart failure with improved ejection fraction (HFimpEF) has been regarded as a new heart failure (HF) type in 2022. However, studies on the impact of left ventricular ejection fraction (LVEF) trajectories on the prognosis of patients with HFimpEF are scarce. In this study, we investigated dynamic trajectories of LVEF and different clinical outcomes in HFimpEF. This was a multi-center study included patients diagnosed with HF with reduced ejection fraction (HFrEF) between January 1, 2015, and October 31, 2022. Enrolled patients were divided into HFimpEF and persistent HFrEF groups. To further investigate different LVEF trajectories in HFimpEF patients, they were classified into persistent HFimpEF and transient HFimpEF subgroups. Adverse clinical outcomes encompassed all-cause death, cardiovascular death, and HF-related rehospitalization. A total of 734 patients were included (HFimpEF: n = 162; persistent HFrEF: n = 572). Cox regression analysis revealed that compared with persistent HFrEF, patients with HFimpEF experienced a lower risk of all-cause and cardiovascular death. Subgroup analysis determined that only 113 (69.75%) patients maintained an LVEF exceeding 40%. Cox regression analysis revealed that persistent HFimpEF patients had a lower risk of all-cause and cardiovascular death compared to those with transient HFimpEF. Finally, multivariate logistic analysis showed that gender and high-density lipoprotein cholesterol levels were independent predictors of persistent HFimpEF. HFimpEF does not accurately represent HF recovery, given that there are different trajectories of LVEF in HFimpEF. Patients with persistent HFimpEF experience better clinical outcomes, highlighting clinicians should identify clinical modifiable factors to maintain a stable HF stage for better prognosis.

Rab2A-mediated Golgi-lipid droplet interactions support very-low-density lipoprotein secretion in hepatocytes.

Lipid droplets (LDs) serve as crucial hubs for lipid trafficking and metabolic regulation through their numerous interactions with various organelles. While the interplay between LDs and the Golgi apparatus has been recognized, their roles and underlying mechanisms remain poorly understood. Here, we reveal the role of Ras-related protein Rab-2A (Rab2A) in mediating LD-Golgi interactions, thereby contributing to very-low-density lipoprotein (VLDL) lipidation and secretion in hepatocytes. Mechanistically, our findings identify a selective interaction between Golgi-localized Rab2A and 17-beta-hydroxysteroid dehydrogenase 13 (HSD17B13) protein residing on LDs. This complex facilitates dynamic organelle communication between the Golgi apparatus and LDs, thus contributing to lipid transfer from LDs to the Golgi apparatus for VLDL2 lipidation and secretion. Attenuation of Rab2A activity via AMP-activated protein kinase (AMPK) suppresses the Rab2A-HSD17B13 complex formation, impairing LD-Golgi interactions and subsequent VLDL secretion. Furthermore, genetic inhibition of Rab2A and HSD17B13 in the liver reduces the serum triglyceride and cholesterol levels. Collectively, this study provides a new perspective on the interactions between the Golgi apparatus and LDs.

Effects of Vitamin D Supplementation and a Cafeteria Diet on Various Parameters in the Next Generation of Rats with Metabolic Syndrome

Background/Objectives: Metabolic Syndrome (MetS) is an increasingly widespread public health problem worldwide. MetS is associated with a cafeteria diet characterized by high fat and high simple carbohydrates. A cafeteria diet significantly affects serum glucose, creatine, urea, triglyceride, cholesterol and MetS parameters such as ALT, AST and ALP. Due to its epigenetic effects, vitamin D is important in controlling MetS parameters and minimizing MetS findings in subsequent generations. Methods: In this study, the effect of weekly 0.3 mL (1.000 IU/week) vitamin D intervention on MetS parameters was investigated in parental rats developing high-fructose MetS and their offspring. Offspring of MetS rats receiving and not receiving vitamin D supplementation were divided into four different groups and exposed to a cafeteria diet and vitamin D supplementation for eight weeks. Results: It was shown that parental rats in the intervention group had lower serum urea, glucose, creatine, total cholesterol, ALP, AST and ALT levels (p < 0.05). Serum urea, glucose, creatine, ALT, AST, ALP, triglyceride, total cholesterol levels and body weights were lower and HDL levels were higher in the offspring (p < 0.05). However, initial serum ALT and AST values were higher in the offspring of MetS parent rats receiving vitamin D supplementation and in the offspring of rats not receiving supplementation than in the offspring of supplemented parents. Conclusions: In conclusion, it was found that vitamin D supplementation improved MetS parameters in parent rats, positively affected MetS parameters in offspring rats despite an inadequate diet, and positively affected some MetS parameters by affecting epigenetic pathways in offspring born to MetS mothers.

Models incorporating physical, laboratory and gut metabolite markers can be used to predict severe hepatic steatosis in MAFLD patients.

Metabolic-associated fatty liver disease (MAFLD) induced-severe hepatic steatosis poses significant health risks. Early prediction of this condition is crucial for prompt intervention. Short-chain fatty acids (SCFAs) and tryptophan are gut metabolites correlated with MAFLD pathogenesis in the gut-liver axis. This study aims to construct prediction models for severe hepatic steatosis by including SCFAs and tryptophan metabolites. This study enrolled 83 participants from the outpatient department in 2023. Physical measurements, serum metabolic and inflammatory markers, metabolites of serum SCFAs and tryptophan were collected. Severe hepatic steatosis was diagnosed using vibration-controlled transient elastography and abdominal sonography. All 40 (48.2%) participants diagnosed with severe hepatic steatosis had MAFLD, while approximately three-quarters of those without severe hepatic steatosis had MAFLD. In comparison to the non-severe hepatic steatosis group, individuals with severe hepatic steatosis exhibited higher levels of waist and arm circumference, serum triglyceride (TG), and lower levels of serum high-density lipoprotein cholesterol (HDL-C) and AST/ALT ratio. They also had higher serum levels of lipopolysaccharide-binding protein, isovaleric acid, and propionic acid, and lower levels of 3-methylvaleric acid, indole-3-propionic acid, and indoxyl sulfate. Models incorporating these markers predicted severe hepatic steatosis. One model additionally included waist circumference and triglyceride-glucose index, while the other incorporated arm circumference and TG/HDL-C ratio. The area under the curve reached 0.958 and 0.938, respectively (p < 0.001). SCFAs and tryptophan metabolites are valuable in predicting severe hepatic steatosis. Further research is needed to investigate the roles of these metabolites in MAFLD.

Correlations between nutritional indicators and cognitive function in patients with stable schizophrenia in a hospital setting.

Cognitive impairment is a core feature of schizophrenia, and it is now clear that there is a link between nutritional indicators and cognitive functioning. This study aimed to investigate correlations between three nutritional indicators (prognostic nutritional index [PNI], geriatric nutritional risk index [GNRI], and controlling nutritional status score [CONUT]) and cognitive function in hospitalized patients with stable schizophrenia. A total of 235 patients who were hospitalized with stable schizophrenia were included. Patient demographic information was collected through self-reports or electronic medical records, and cognitive function was assessed using the Montreal Cognitive Assessment in China (MoCA-C). Information on serum albumin and total cholesterol levels, lymphocyte counts, and body mass index during the stable stage of schizophrenia was collected to calculate the PNI, GNRI, and CONUT scores, according to their respective calculation criteria. Covariate-adjusted linear regression model and ordered logistic regression model were constructed to determine the relationship between nutritional indicators and cognitive function. Overall, 90.2% of the patients were under the age of 60 years, and males comprised 60% of all patients. The median scores for MoCA-C, PNI, GNRI, and CONUT in hospitalized patients with stable schizophrenia were 18 (12,23), 52.85 (50.25,55.90), 110.85 (105.80,116.21), and 3 (3,3), respectively. The results of the correlation analysis showed that only PNI was associated with MoCA-C scores (r = 0.15, P = 0.021). This relationship was further confirmed by covariate-adjusted linear regression modeling (β = 0.147, 95%CI:0.049-0.351, p = 0.01) and ordered logistic regression modeling (OR = 0.054, 95%CI:0.001-0.106, p = 0.046). The findings revealed a significant correlation between PNI scores and MoCA-C scores in hospitalized patients with stable schizophrenia.

Relationship between physical activity and abdominal obesity and metabolic markers in postmenopausal women

This study aimed to investigate the impact of physical activity indicators monitored by the POLAR accelerometer on body obesity indicators, metabolic syndrome parameters, and energy metabolism hormones in postmenopausal women. Was included 71 participants from this study program (68.8 ± 4.3 years). We divided participants into LPA and MVPA groups based on their level of moderate to vigorous physical activity per week; Physical activity levels over 7 days were assessed using a POLAR accelerometer, with daily step counts and sedentary time recorded. Measurements included waist circumference, visceral fat volume, body fat percentage, blood pressure, fasting blood glucose, triglyceride levels, HDL cholesterol, and energy metabolism hormone levels (leptin, resistin, adiponectin). The MVPA group displayed lower waist circumference, body fat percentage, abdominal fat, and BMI compared to the LPA group (p < 0.05). A significant negative correlation was observed between daily step count and obesity indicators, including waist circumference (r = -0.301), body fat percentage (r = -0.295), abdominal fat (r = -0.318), and BMI (r = -0.238). Conversely, sedentary time showed a positive correlation with obesity indicators such as waist circumference (r = 0.258), body fat percentage (r = 0.239), and abdominal fat (r = 0.244). Moreover, daily step count exhibited a significant negative correlation with leptin levels (r = -0.245), while sedentary time was positively correlated with the energy metabolic factor leptin (r = 0.279). Waist circumference demonstrated significant positive correlations with triglycerides, blood glucose, adiponectin, resistin, and leptin levels. Postmenopausal women who engage in at least 150 min of MVPA weekly show lower obesity indices. There is a significant correlation between physical activity levels and obesity indicators, which relate to metabolic syndrome and energy metabolism factors. Thus, increased physical activity may help prevent metabolic syndrome and cardiovascular diseases in this population.

Factors Associated With Infusion Reactions in Patients With Breast Cancer Receiving Trastuzumab.

Trastuzumab (TRA) is a key drug in human epidermal growth factor receptor type 2 (HER2)-positive breast cancer treatment. Infusion reactions (IR) with TRA are frequently observed in practice. Although the efficacy of premedication has been previously reported, it remains uncommon. The probability of severe IR due to TRA is low; however, when it does occur, it is associated with patient discomfort and expenditure of medical resources. This study aimed to analyze the factors associated with the occurrence of IR in patients with breast cancer who received TRA. We retrospectively studied 204 patients who underwent TRA for breast cancer treatment between September 2008 and June 2023, identifying factors influencing the occurrence of IR at the time of TRA administration. A total of 182 patients were included in this study, and the incidence of IR was 25.8% (47/182 patients). Multiple logistic regression analysis showed that pertuzumab (PER) use, high alkaline phosphatase (ALP), and low high-density lipoprotein (HDL) cholesterol levels were associated with IR. IR should be considered when PER is combined with TRA. ALP and HDL cholesterol levels may be predictive markers of TRA-induced IR in patients with breast cancer.

Spirulina Unleashed: A Pancreatic Symphony to Restore Glycemic Balance and Improve Hyperlipidemia and Antioxidant Properties by Transcriptional Modulation of Genes in a Rat Model

Hyperlipidemia is the root cause of numerous chronic conditions, leading to high mortality rates around the globe. Spirulina (Arthrospira platensis) microalgae serve as a promising reservoir of bioactive compounds with diverse pharmacological properties. The current study examined the nutritional profile of spirulina powder in relation to strict glycemic control, specifically focusing on its potential to lower lipid levels. In an in vivo investigation, normal healthy male Wistar albino rats (n = 60) were divided into two groups: a negative control group (NC) of ten rats and a high-fat diet group (n = 50) that were fed a cholesterol-rich diet until their cholesterol levels reached or exceeded 250 mg/dL. Subsequently, the hypercholesterolemic rats were then randomly allocated to several treatment groups: a positive control (PC); a standard treatment diet (STD) involving fenofibrate at a dose of 20 mg/kg body weight; and three experimental groups (T1, T2, and T3) that received spirulina powder supplementation at doses of 300, 600, and 900 mg per kg body weight, respectively, for the period of 12 weeks. Blood samples were analyzed for oxidative stress biomarkers, insulin levels, lipid profiles, liver function, and expression of gene levels in the diabetogenic pathway. The study utilized spectrophotometric colorimetric methods to identify oxidative stress biomarkers, serum kit methods to measure lipid profiles and liver enzymes, and the assessment of qPCR for mRNA quantity. According to the research findings, spirulina powder has certain noteworthy features. It had the greatest quantity of chlorogenic acid (4052.90 µg/g) among seven phenolics and two flavonoid compounds obtained by HPLC-UV analysis. Furthermore, the proximate analysis demonstrated that spirulina is high in protein (16.45 ± 0.8%) and has a significant energy yield of 269.51 K-calories per 100 g. A maximal spirulina dose of 900 mg/kg/wt significantly lowered oxidative stress, cholesterol, triglyceride, low-density lipoproteins (LDL), and insulin levels (p ≤ 0.05). In contrast, high-density lipoprotein (HDL) and total antioxidant capacity (TAC) levels increased significantly (p ≤ 0.05) compared to all other groups, except the NC group. The study provides remarkable proof about the pharmacological impact of spirulina powders. Significant reductions (p ≤ 0.05) in liver enzymes {alanine aminotransferase (ALT) and aspartate aminotransferase (AST)} were observed across all treatment groups, with the exception of the NC, compared to the positive control. The treatment groups had significantly greater gene expression levels of INS-1, PDX-1, IGF-1, and GLUT-2 than the positive control group (p ≤ 0.05). These findings highlight spirulina’s potential as a long-term regulator of hyperglycemia in rat models with induced hyperlipidemia, owing to its phenolic bioactive components that serve as antioxidants.

Health Disparities Among Ultra-Orthodox and Non-Ultra-Orthodox Residents in Neighboring Cities in Israel: A Cross-Sectional Study.

Socioeconomic status and religion are associated with health indicators. This study compared the correlations between religious observance, socioeconomic status, and select health indicators among adults in neighboring cities in Israel based on data collected from the Maccabi Health Services database. One city is characterized by religious observance, while the other is primarily secular. Lower smoking rates and higher rates of low cholesterol, triglycerides and LDL levels were observed in the religious city. No significant differences were found for low HDL rates or diabetes. Unique characteristics of populations must be considered when planning health interventions.

The Demographic and Lifestyle Characteristics of Patients with Familial Hypercholesterolemia Referred to a Dyslipidemia Clinic: A Cross-Sectional Single-Center Study

Background: Familial hypercholesterolemia (FH) is one of the most prevalent dyslipidemia disorders. This study investigated the demographic and lifestyle characteristics of patients with FH referred to a dyslipidemia clinic. Methods: This 5-year, single-center cross-sectional study focused on patients with low-density lipoprotein cholesterol (LDL-C) levels higher than 190 mg/dL referred to a dyslipidemia clinic in Tehran, Iran, between 2017 and 2022. The study examined their demographics, physical activity, and anxiety within the FH cohort. Results: A total of 1724 patients were referred to the dyslipidemia clinic. Of these patients, 44 were diagnosed with definite FH. The mean age and LDL-C level of the FH cohort were 38.84±16.85 years and 315.95±81.73 mg/dL, respectively. A significant correlation was found between LDL-C and body mass index (BMI) (correlation coefficient = -0.31, P=0.031) and total sleep duration (correlation coefficient = -0.40, P&lt;0.000). No correlation was observed between age and physical activity or LDL-C levels. Additionally, no significant correlation was detected between the Dutch score and patients’ LDL-C, BMI, age, or physical activity. Regression analysis indicated that BMI and total sleep duration were independent predictors of LDL-C in the FH cohort. Conclusion: Investigating and identifying patients’ demographic and lifestyle characteristics is the first step in planning efficient and effective management strategies for chronic diseases, such as FH. Establishing a patient registry for chronic diseases enhances understanding of the target population and enables healthcare providers to design and implement appropriate preventive and control strategies.

Pharmacokinetic Drug-Drug Interaction between Cilostazol and Rosuvastatin in Healthy Participants.

Cilostazol improves ischemic symptoms and prevents recurrence following cerebral infarction, and rosuvastatin reduces cholesterol levels. However, no reports exist on the pharmacokinetic interactions between these two drugs in healthy adults. This study evaluated the pharmacokinetic (PK) interactions and safety of cilostazol and rosuvastatin when co-administered to healthy male participants. A randomized, open-label, multiple-dosing, two-arm, two-period study was conducted. Arm A had 30 participants receiving 200 mg cilostazol daily and arm B had 27 participants receiving 20 mg rosuvastatin daily for 7 days. In period 2, both arms received a combination of 200 mg cilostazol and 20 mg rosuvastatin daily for 7 days following a 7-day washout period. Plasma concentrations of cilostazol, its metabolites, and rosuvastatin were quantified using liquid chromatography-tandem mass spectrometry. Fifty-seven participants were randomized, and 44 completed the study. The geometric mean ratio (GMR) and 90% confidence intervals (CI) for maximum plasma concentration at steady state (Cmax,ss) and area under the plasma concentration-time curve during the dosing interval at steady state (AUCtau,ss) indicated no significant interaction between cilostazol and rosuvastatin. Safety assessments showed comparable profiles to individual drug administration, with no significant adverse events. The repeated co-administration of cilostazol and rosuvastatin in healthy male participants resulted in minor PK interactions and exhibited a safety and tolerability profile similar to those of the individual drugs. This suggested that the combined regimen is well tolerated and does not necessitate dose adjustments. ClinicalTrials.Gov identifier no. NCT06568133.

The association between non-HDL cholesterol and high-grade pancreatic neuroendocrine neoplasms.

High-density lipoprotein cholesterol (HDL-c) plays an important role in tumorigenesis in several endocrine-related cancers. Few studies have shown the effect of non-HDL-c in malignant tumors. The present study aimed to identify the association between non-HDL-c and high-grade pancreatic neuroendocrine neoplasms (PNENs). A total of 197 PNEN patients who underwent surgery were analyzed retrospectively. Clinical and histopathological features, such as patients' age and sex, tumor location and size, tumor grade, the level of serum total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c) and fasting plasma-glucose levels were obtained. Non-HDL-c was calculated as total cholesterol - HDL-c. The relationships between those features and high-grade PNENs were identified using logistic regression analysis. Among the 197 patients with PNENs, a lower HDL-c level was more common seen in patients with poorly differentiated PNENs than in those with well-differentiated PNENs (P < 0.05). The non-HDL-c/HDL-c ratio was greater in patients with poorly differentiated PNENs than in those with well-differentiated PNENs (P < 0.01). Similarly, a greater proportion of patients with a non-HDL-c/HDL-c ratio larger than 5 was found in patients with poorly differentiated PNENs than in those with well-differentiation PNENs (P < 0.01). Multivariate logistic analysis showed that the non-HDL-c/HDL-c ratio was positively associated with poorly differentiated PNENs (odds ratio (OR) = 1.45, 95% conference interval (CI):1.13-1.87). Similarly, the risk of poorly differentiated PNENs increased significantly in patients with a non-HDL-c/HDL-c greater than 5 (OR = 14.13, 95%CI: 2.98-66.89). The risk of high-grade PNENs increased in patients with a high non-HDL-c/HDL-c ratio (OR = 1.27, 95% CI: 1.04-1.55), and the risk also increased markedly when the ratio was greater than 5 (OR = 5.00, 95%CI: 1.28-19.49). A high ratio of non-HDL-c/HDL-c was associated with high-grade PNENs or poorly differentiated PNENs.

Evaluation of thiol/disulphide and oxidant-antioxidant status of dairy cows in periparturient and post-partum period.

Thiol/disulphide homeostasis (TDH) has a critical role in many cellular activities such as antioxidant protection. Alterations of oxidative stress in the transition period play an important role in development of some diseases and disorders in dairy cows. The purpose of this study is to assess the total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), total thiol, native thiol, disulphide and lipid profile in Simmental and Montofon dairy cows (aged 2-3) before and after calving. Blood samples were collected 233-280 days of pregnancy and the 30 days of post-partum. Serum total thiol, native thiol and disulphide levels were determined as well as TAS, TOS and paraoxonase-1 (PON-1) levels were measured using colorimetric assays. Triglycerides (TG), total cholesterol, HDL cholesterol and LDL cholesterol levels were measured with an automatic analyser. Total thiol (p=0.038) and disulphide (p=0.015) levels were higher after calving compare to pregnancy in Montofon. TAS was found lower (p<0.001), and OSI was higher in both breeds (Montofon p=0.012, Simmental p=0.028) after calving than in pregnancy. When compared between pregnancy and after calving levels in the same breed, HDL was found to be higher after calving (p<0.001) and TG was lower after calving (p=0.020) in Montofon. PON (p=0.090), HDL (p<0.001) and cholesterol levels were found higher (p<0.001) and TG level was lower (p<0.001) after calving in Simmental. According to our results, we observed different responses between two breeds before and after calving. There are few studies about TDH in animal research, and this is the first study in the literature that evaluates the TDH along with oxidative stress and lipid profiles in dairy cows in the periparturient and post-partum period.

Interplay Between Western Diet and Mammary Cancer: Data from a Chemically-induced Model in Wistar Rats.

This study aimed to investigate the influence of Western diet on mammary cancer in Wistar female rats, focusing on systemic responses and tumor development. Twenty-eight Wistar female rats were acclimatized and divided into four experimental groups (n=7 each): Western diet (WD), Western diet with N-methyl-N-nitrosourea (MNU) administration (WD+MNU), standard diet (CTR), and standard diet with MNU administration (CTR+MNU). MNU was administered intraperitoneally at 50 mg/kg at seven weeks of age to induce mammary cancer. The 20-week experiment involved monitoring animal weight, food and water intake. At the end of the study, rats were euthanized, and blood samples and organs were collected for hematological and plasma biochemical analysis, oxidative stress, and histo-pathological and immunobiological evaluations of the tumors. No significant differences were found in body weight, composition, or organ weights, but the WD group showed reduced food and water intake and lower cholesterol levels. Leptin and adiponectin levels were higher in the WD+MNU group, suggestive of changes in appetite regulation. Histopathological analysis showed malignant tumors in both MNU-induced groups. However, WD groups had fewer tumors compared to the CTR+MNU group. WD led to higher feed efficiency and increased visceral adipose tissue but decreased systemic cholesterol and triglyceride levels. While this diet resulted in lower tumor incidence, the volume and weight of the tumors were higher. Additionally, the WD decreased ERα and progesterone receptor immunoexpression, while Ki-67 immunoexpression was elevated.

Sex-specific Associations between Left Ventricular Remodeling at MRI and Long-term Cardiovascular Risk.

Background Left ventricular mass (LVM) is an established marker of cardiovascular risk; however, long-term follow-up studies in individuals with low to intermediate risk are lacking. Purpose To assess the sex-specific association of LVM measured with cardiac MRI with cardiovascular outcomes in those with a less than 20% 10-year risk of cardiovascular disease (CVD). Materials and Methods A total of 1528 volunteers older than 40 years of age with no history of CVD, a 10-year risk of CVD of less than 20%, and a B-type natriuretic peptide level greater than their sex-specific median underwent cardiac MRI between June 2008 and February 2013 as part of the Tayside Screening for Cardiac Events, or TASCFORCE, prospective study. LVM was indexed to body surface area, and the LVM-to-volume ratio was calculated. Follow-up for cardiovascular events was performed using national electronic health records. Cox proportional hazard models and Kaplan-Meier curves were applied to assess the impact of LVM. Results A total of 1495 participants (mean age, 54.5 years ± 8.3 [SD]; 925 female, 570 male) completed cardiac MRI, with a median follow-up of 10 years (IQR, 3 years). In female participants, LVM was associated with age, blood pressure, smoking status, and cholesterol level, while in male participants, LVM was associated with age and blood pressure. In female participants, the LVM-to-volume ratio was associated with cardiovascular events (hazard ratio [HR], 2.3 [95% CI: 1.1, 4.9] for the highest quartile vs the lowest quartile), while the LVM was not. In male participants, the LVM was associated with cardiovascular events (HR, 3.2 [95% CI: 1.5,7.0] for the highest quartile vs the lowest quartile), while the LVM-to-volume ratio was not. Conclusion In those with low to intermediate risk without established CVD, different remodeling patterns predict cardiovascular events, with increased LVM predictive in male participants, while LVM-to-volume ratio is predictive in female participants. © RSNA, 2024 Supplemental material is available for this article.
