Differences In Total Cholesterol Research Articles

Correlations Between the Neutrophil-Lymphocyte Ratio, Platelet-Lymphocyte Ratio, and Serum Lipid Fractions With Neovascular Age-Related Macular Degeneration.

Introduction Age-related macular degeneration, a chronic and progressive disease, is one of the leading causes of vision loss globally among the elderly population. Multiple hypotheses have been proposed regarding its pathogenesis, including the presence of lipid metabolism alteration. Dysfunctional lipid handling within retinal pigment epithelial cells has been implicated in the accumulation of lipofuscin and subsequent induction of oxidative stress and inflammation, all contributing to retinal degeneration. The present study aims to comparatively analyze the serum lipid fractiondistributions in patients with neovascular age-related macular degeneration (AMD) and controls. Materials and methods A retrospective study was carried out between January 2021 and December 2023 on 91 naïve patients with neovascular AMD and 90 controlsadmitted for routine cataract surgery. All subjects underwent a comprehensive ophthalmological exam, including ophthalmoscopy and optical coherence tomography (OCT) with central macular thickness (CMT) measurement. A complete blood count with differential and lipid fractions values was analyzed. The neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG) were comparatively analyzed between the control group and the test group. Results The groups were comparable in terms of age (73.84 ±7.52 years for the neovascular AMD group vs 72.1±10.92 years in controls; p=0.8) and gender distribution (p=0.243). The mean NLR and PLR values were slightly higher in the AMD groupbut not statistically significant (p=0.51, p>0.99, respectively). Comparative analysis of lipid profile fractions showed significantly higher HDL-C values in the exudative AMD group compared to normal subjects (61.27±19.4 mg/dL vs 50.99±7.86 mg/dL, p=0.006). Also, the proportion of subjects with HDL-C>60 mg/dL was higher in the exudative AMD group (p=0.014). There were no significant differences in total cholesterol (189.77±53.39 mg/dL vs 190.43±37.84 mg/dL, p=0.681), LDL-C, and TG. Logistic regression analysis showed that serum HDL-C and HDL-C values >60 mg/dL are significantly associated factors with neovascular AMD. However, there is no statistical correlation between the values of these biochemical parameters and visual acuity or CMT in the neovascular AMD patient group. Conclusions There were no correlations between NLR and PLR with neovascular AMD in the study group. Higher HDL-C valuesexceeding 60 mg/dL were associated with neovascular age-related macular degeneration and could represent a possible therapeutic target in neovascular AMD.

Do polyphenols affect body fat and/or glucose metabolism?

Obesity is reaching epidemic proportions with 51% of the population expected to be obese by 2030. Recently, polyphenols have been highlighted as an effective approach to managing obesity and associated risks. Polyphenols are a large class of bioactive plant compounds classified into two major categories: flavonoids which are distinguished by the fundamental C6-C3-C6 skeleton and non-flavonoids. This systematic review evaluated the effect of different polyphenol sources in overweight and obese people with and without type 2 diabetes. The primary outcome was lipid profile and the secondary outcomes were blood glucose, HbA1c (%), HOMA-IR, weight, and body mass index. A search was undertaken in PubMed, Web of Science, Medline, and Wiley for randomized control trials that assessed different sources of polyphenols in overweight and obese people with or without type 2 diabetes. The quality of the included studies was assessed using the National Heart, Lung, and Blood Institute Quality Assessment Tool. The search yielded 935 studies, of which six randomized control trials met the inclusion criteria. Five studies found no significant difference in lipid profile between the control and intervention groups in triglycerides, total cholesterol, LDL cholesterol, and HDL cholesterol. However, one study showed significant differences in triglycerides (p = 0.04) and HDL cholesterol (p = 0.05) between the two groups with no significant difference in total cholesterol and LDL cholesterol. There were no significant changes in blood glucose observed in the included studies, with only two studies reporting a significant difference in A1c between the groups. Four studies found no difference in HOMA-IR, while one study showed a significant decrease in HOMA-IR in the intervention group compared to the control group. Three studies reported no difference in BMI or weight between the two groups. The data associated with the specific health benefits of polyphenols and their sources in people with overweight, obese, and type 2 diabetes are still limited, so further research is required to support their use and prove their benefits.

#456 Efficacy and safety of iptacopan in patients with primary IgA nephropathy: interim analysis results of the Phase 3 APPLAUSE-IgAN study

Abstract Background and Aims Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis. An unmet need for targeted disease-modifying treatments addressing its pathophysiology remains. There is compelling evidence for involvement of the alternative complement pathway (AP) in IgAN. Iptacopan binds to Factor B and specifically inhibits the AP. The APPLAUSE-IgAN trial is evaluating the efficacy and safety of iptacopan vs placebo, on top of optimized supportive therapy, in patients with IgAN. Here we present the results of the pre-specified interim analysis (IA) with a focus on the results for key subgroups. Method APPLAUSE-IgAN (NCT04578834), a Phase 3, multicentre, randomised, double-blind, placebo-controlled trial, enrolled adults with biopsy-confirmed IgAN with proteinuria ≥1 g/g by urine−protein creatinine ratio from 24-hour urine collection (UPCR-24h) despite being on a stable dose of maximally tolerated renin-angiotensin-system inhibition (RASi) for 3 months, with or without other background therapy such as sodium-glucose transport protein 2 inhibition (SGLT2i). Patients were randomized 1:1 to iptacopan 200 mg or placebo twice daily for 24 months while remaining on stable supportive therapy. The primary objective of the prespecified IA was to demonstrate superiority of iptacopan vs placebo in reducing UPCR-24h at Month 9 (M9) in the main study population (estimated glomerular filtration rate [eGFR] ≥30 mL/min/1.73 m2 at baseline). Subgroup analyses included baseline age, sex, Asia vs non-Asia region, proteinuria, eGFR, and SGLT2i use. Efficacy analyses were performed on the first 250 patients (n = 125 each for iptacopan and placebo) who reached the M9 visit or discontinued from the study. Safety analyses included all patients of the main population who had received treatment by the time of the IA (iptacopan, n = 222; placebo, n = 221). Results Baseline demographics and disease characteristics were similar between the two arms (Table) and indicative of patients at high risk of IgAN disease progression. Iptacopan was superior to placebo in reducing proteinuria, with reduction in UPCR-24h at M9 relative to baseline of 38.3% (95% CI: 26.0%, 48.6%; 1-sided p < 0.0001) vs placebo (Figure). Subgroup analyses showed that treatment effect consistently favoured iptacopan regardless of baseline age, sex, Asia vs non-Asia region, UPCR-24h or eGFR levels, or SGLT2i use as part of the supportive care (Figure). Treatment-emergent adverse events (TEAEs) occurred in 138 (62.2%) iptacopan vs 153 (69.2%) placebo patients, with the majority being of mild to moderate severity. Treatment-emergent serious AEs were reported in 18 (8.1%) and 11 (5.0%) patients in the iptacopan and placebo arms, respectively. TEAEs leading to treatment discontinuation occurred in 6 patients (2.7%) in each arm. No deaths were reported. Iptacopan treatment did not lead to clinically relevant differences in total cholesterol, low-density lipoprotein cholesterol, and serum triglycerides compared with placebo. Conclusion APPLAUSE-IgAN, the first Phase 3 study confirming the relevance of the AP in IgAN, demonstrated superiority of iptacopan vs placebo, with a significant reduction in proteinuria at M9 (38.3%) that was consistent across key subgroups evaluated. Iptacopan was well tolerated with a favourable safety profile.

An analysis of the association between breast density and body mass index with breast cancer molecular subtypes in early breast cancer: data from a Spanish population.

Breast cancer is an important health problem, like obesity and dyslipidemia, with a strong association between body mass index (BMI) and breast cancer incidence and mortality. The risk of breast cancer is also high in women with high mammographic breast density (MBD). The purpose of this study was to analyze the association between BMI and MBD according to breast cancer molecular subtypes. This transversal, descriptive, multicenter study was conducted at three Spanish breast cancer units from November 2019 to October 2020 in women with a recent diagnosis of early breast cancer. Data were collected at the time of diagnosis. The study included 162 women with a recent diagnosis of early breast cancer. The median age was 52years and 49.1% were postmenopausal; 52% had normal weight, 32% overweight, and 16% obesity. There was no association between BMI and molecular subtype but, according to menopausal status, BMI was significantly higher in postmenopausal patients with luminal A (p = 0.011) and HER2-positive (p = 0.027) subtypes. There was no association between MBD and molecular subtype, but there were significant differences between BMI and MBD (p < 0.001), with lower BMI in patients with higher MBD. Patients with higher BMI had lower HDL-cholesterol (p < 0.001) and higher insulin (p < 0.001) levels, but there were no significant differences in total cholesterol or vitamin D. This study showed higher BMI in luminal A and HER2-positive postmenopausal patients, and higher BMI in patients with low MBD regardless of menopausal status.

The Effect of Dangke on Changes in Total Cholesterol and Triglyceride Levels in Obesity White Rats

Background: Obesity is the excessive accumulation of fat in the body which disrupts health with the risk of metabolic system disorders in the form of increased cholesterol and triglycerides in the blood. The prevalence of obesity in Makassar City is 24.05%, which is the highest prevalence in South Sulawesi. Dangke contains Lactic Acid Bacteria in the form of probiotics which have the ability to anti-inflammatory mechanisms and fat metabolism in the body. Purpose: To determine the effect of dangke on changes in total cholesterol and triglyceride levels in obese white rats. Method: Pure experimental research design with Pre Post Randomized Clinical Trial Design. Data analysis used the independent T test/Mann-Whitney test and paired T test/Wilcoxon Signed Rank Test with a value of &lt;0.05. Results: Comparison of total cholesterol and triglyceride levels before and after intervention in the control group showed p-values of 0.12 and 0.01, meaning there was no significant change in cholesterol and there was a significant change in triglycerides. Comparison of total cholesterol and triglyceride levels before and after intervention in the dangke group p-values were 0.47 and 0.12, meaning there was no significant change in total cholesterol and triglyceride levels. The difference in total cholesterol and triglyceride levels before the intervention in the control and dangke groups showed p-values of 0.37 and 0.78, meaning there was no significant change in total cholesterol and triglyceride levels. The difference in total cholesterol and triglyceride levels after intervention in the control and dangke groups obtained p-values of 0.38 and 0.32, which means there was no significant change in total cholesterol and triglyceride levels. Conclusion: There was no significant change in total cholesterol and triglyceride levels in the control and dangke groups when given dangke, but there was a tendency to decrease total cholesterol and triglyceride levels after the intervention in the dangke group.

Biological assessment of the omega-3 status after omega-3 enriched dietary during an active seasonal performance on soccer players

BackgroundTo assess the physiological change of blood fatty acid composite during the seasonal performance of soccer players with omega-6/omega-3 polyunsaturated fatty acid balanced dietary supplementation.MethodsThis study included 20 healthy and trained male soccer players. During the study, data collection was performed three times (pre-, mid-, post-season). Anthropometric data collection and blood sampling for the assessment of the omega index were performed. The mid- and post-seasonal data were compared with baseline data collected before the starting season (pre-seasonal data).ResultsElevated levels of omega-3, HS-omega, and trans fatty acid were observed in both the mid- and post-seasonal data. During the season, the levels of omega-6/omega-3 and saturated fatty acid decreased, whereas there were no differences in total cholesterol, cholesterol LDL, HDL, BUN/Cr, HbA1c (NGSP), and cystatin C.Conclusionsn-3 PUFA-enriched dietary supplementation might alter blood omega-3 indices in soccer players during the season.

A systematic review and meta-analysis of serum lipid concentrations in people with Down syndrome.

Down syndrome (DS) is the most prevalent chromosomal disorder, being the leading cause of intellectual disability. The increased life expectancy of individuals with DS has led to a shift in the incidence of non-communicable chronic diseases, resulting in new concerns, particularly cardiovascular disease (CVD) and Alzheimer's disease. This study aimed to analyse the blood lipid profile of a large DS cohort to establish a baseline for evaluating health risk parameters. A comprehensive literature search was conducted on PubMed and Virtual Health Library databases to identify original articles published before July 2022. Selected studies were included in the meta-analysis. Fifteen studies reporting serum lipid levels in individuals with DS were incorporated into the analysis. The meta-analysis used the means and standard deviations extracted from the selected studies. The analysis encompassed 671 participants in the DS group and 898 euploid controls. The results indicated significant differences in total cholesterol [C] (mean difference [MD]: -3.34; CI: 95%: -4.94 to -1.73; P<0.0001), HDL-C (MD: -3.39; CI: 95%: -6.72 to -0.06; P=0.05) and triglycerides (MD: 21.48; CI: 95%: 9.32 to 33.65; P=0.0005) levels between individuals with DS and their control counterparts. Individuals with DS have less favourable blood lipid concentrations than their controls, particularly HDL-C, triglycerides, and total-C, even when grouped by age. These findings underscore the importance of closer monitoring of lipid profiles in people with DS and the necessity for specific cut-offs for this population, considering the risk for ischemic heart and Alzheimer's diseases.

Effects of Whole-Plant Corn Silage on Growth Performance, Serum Biochemical Indices, and Fecal Microorganisms in Hezuo Pigs.

In this study, we investigated the effects of the dietary inclusion of different proportions of whole-plant corn silage on growth performance, serum biochemical indexes, and intestinal microorganisms in Hezuo pigs. Thirty-two two-month-old Hezuo pigs (body weight: 7.88 ± 0.81 kg) were randomly divided into four groups of eight pigs (half male, half female) each. The control (CON) group received a basal diet, while the three experimental groups were fed the basal diet, part of which had been replaced with 5%, 10%, and 15% whole-plant corn silage, respectively. The experiment lasted for 127 days, including 7 days of pre-testing and 120 days of formal testing. At the end of the experiment, blood and fecal samples were collected. Compared with the CON group, the feed-to-gain ratio was significantly lower in the 10% test group (p < 0.05), whereas the total protein, albumin, triglyceride, and glucose contents were significantly higher (p < 0.05). No significant differences in total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, creatinine, urea, aspartate aminotransferase, and alanine aminotransferase were observed among the groups (p > 0.05). The addition of whole-plant corn silage to the diet significantly increased alpha diversity in the pig gut based on 16S rRNA gene sequencing. The principal coordinate analysis results showed significant clustering of the different groups (p < 0.05). At the phylum level, the addition of whole-plant corn silage to the diet significantly decreased (p < 0.05) the relative abundance of Firmicutes and significantly increased (p < 0.05) that of Bacteroidetes. At the genus level, the relative abundance of Streptococcus significantly decreased (p < 0.05) with increasing silage supplementation levels, whereas species diversity significantly increased (p < 0.05). In conclusion, 10% is the recommended inclusion ratio for whole-plant corn silage in the diets of pigs.

Elucidating APOE4‐dependent cholesterol dysregulation in endolysosomes related to Alzheimer’s disease biology

AbstractBackgroundAberrant cholesterol processing may be the missing link in the biology of AD, and in our understanding of AD etiology. APOE4 is a major genetic risk factor for AD, and a key player in cholesterol metabolism in the brain. Previous research from our group has shown that APOE4 is related to increased lysosomal cholesterol accumulation in human iPSC‐astrocytes, and altered endolysosomal morphology has been observed in the entorhinal cortex (EC) of aged APOE4 mice. However, it is unclear how endolysosomal cholesterol mistrafficking changes with age.MethodTherefore, we studied endolysosomal cholesterol accumulation in middle (15‐16month) and old age (25‐26month) old mice, enabling us to study these processes already in mid‐life. We used brain sections of humanized APOE mice, looking at different brain regions to study regional vulnerability and temporal progression. Cholesterol was labeled using the novel and highly specific D4H probe, enabling its quantification within the endolysosomal system using immunohistochemistry. Cholesterol and endolysosomal markers were quantified and colocalized using Cellprofiler.ResultOlder APOE4 mice showed an increase of total cholesterol in their brain, and specifically an increase of lysosomal cholesterol. Middle aged mice did not show a difference in total cholesterol, however, there was a specific decrease in early endosomal (EE) and late endosomal (LE) cholesterol only in the entorhinal cortex (EC) of female APOE3 mice, while lysosomal cholesterol was increased in this group (APOE4 and APOE2 showed similar levels). The EE and LE cholesterol differences were specific to neurons, but not the lysosomal cholesterol increase, indicating that non‐neuronal cells play a role. Another striking finding was the increase of neuronal EE cholesterol in the EC of middle aged APOE3 male vs female mice, whereas the reverse was seen in APOE4 brain tissue.ConclusionAltogether these results indicate that endolysosomal cholesterol is a dynamic process throughout aging, which may play and active role in AD biology. There is a noticeable shift from EE and EL cholesterol changes in midlife, to lysosomal cholesterol accumulation in older age, which are APOE‐genotype dependent. Notably, the EC specifically of female mice show the most variable endolysosomal cholesterol levels, and may be involved in increased vulnerability to pathology.

Potential impact of high-density lipoprotein cholesterol in the postoperative outcomes of chronic subdural hematoma patients: multi-institutional study in Korea

BackgroundChronic subdural hematoma (CSDH) is a common clinical situation in neurosurgical practice, but the optimal treatment option is controversial. This study aimed to evaluate the effect of cholesterol-lowering medications on and how they affected the prognoses of CSDH patients.MethodsIn this multi-institutional observational study performed in Korea, data from recently treated CSDH patients were gathered from 5 hospitals. A total of 462 patients were collected from March 2010 to June 2021. Patient clinical characteristics, history of underlying diseases and their treatments, radiologic features, and surgical outcomes were analyzed.ResultsSeventy-five patients experienced recurrences, and 62 had reoperations after the initial burr hole surgery. Among these, 15 patients with recurrences and 12 with reoperations were taking cholesterol-lowering medications. However, the use of medications did not significantly affect recurrence or reoperation rates (P = 0.350, P = 0.336, respectively). When analyzed by type of medication, no clinically relevant differences in total cholesterol (TC), triglyceride (TG), or low-density lipoprotein cholesterol (LDL-C) levels were identified. The combination of a statin drug and ezetimibe significantly elevated high-density lipoprotein cholesterol (HDL-C) levels (P = 0.004). TC, LDL-C, and TG levels did not significantly affect patient prognoses. However, HDL-C levels and recurrence (odds ratio (OR) = 0.96; 95% confidence interval (CI): 0.94–0.99; p = 0.010) were negatively correlated. An HDL-C level of 42.50 mg/dL was identified as the threshold for recurrence and reoperation.ConclusionsIn this study, using cholesterol-lowering medications did not significantly impact the prognosis of patients who underwent surgical management for a chronic subdural hematoma. However, the findings showed that the higher the HDL-C level, the lower the probability of recurrence and reoperation.

Abstract 12350: The Impact of an Electronic Best Practice Advisory on Patients’ Physical Activity and Cardiovascular Risk Profile

Background: Regular physical activity (PA) is one of eight components of cardiovascular health and it is associated with numerous benefits including a lower risk of CVD. Promoting PA to sedentary patients in primary care can result in significant improvements in PA. The aims of this study were to implement a PA counseling intervention using an electronic best practice advisory (BPA), in a preventive cardiology clinic, and to assess changes in PA and CVD risk factors in a sample of patients enrolled in 12 weeks of PA monitoring. Methods: Patients were assessed with the 3-question (days/minutes/intensity) physical activity vital sign (PAVS) via their electronic patient portal prior to an office visit. Those who self-reported less than 50% of current PA recommendations prompted a BPA to their cardiologist to counsel them on improving their PA. Patients were then offered participation in remote patient monitoring wearing a Fitbit for 12 weeks. Blood pressure, waist circumference, lipids, BMI, PA (using the PAVS and Fitbit step-counts) and the six-minute walk test (for cardiorespiratory fitness) were measured at baseline and 12 weeks. Paired t -tests assessed for changes in these CVD risk factors from baseline to 12 weeks. We calculated the percent of participants who achieved a clinically important difference of 25 meters in the six-minute walk test. Results: The enrolled sample (n=59) were primarily female (51%), White adults (76%) with a mean age of 61.13±11.6 years. There was significant improvement in moderate-to-vigorous PA as self-reported by the PAVS (43±86 vs. 114±157, p=.005). There was no significant difference between week 2 step counts (baseline) and week 12 (p=.07). There was significant improvement in the distance covered (in meters) during the six-minute walk test (469±108 vs. 494±132, p=.0034) and 23 participants (42%) improved at least 25 meters. There were also significant differences in total cholesterol (163±51 mg/dl at baseline vs. 148±45mg/dl at 12 weeks; p=.0.02). No other improvements in CVD risk factors were noted. Conclusion: Patients who reported low PA and triggered a BPA for PA counseling had improvements in some, but not all, CVD risk factors. Additional counseling may be needed to improve and maintain PA levels in patients at risk of CVD.

Effects of soda water on blood lipid and metabolic profiling of urine in hyperlipidemia rats using UPLC/Triple-TOF MS

The effects of a natural soda water (Shi Han Quan, SHQ) on hyperlipidemia and the changes of urine metabolic profiling by metabolomics techniques were investigate. Thirty six Wistar rats weighing 160–200 g were divided into control group, hyperlipidemia (HL) group, and hyperlipidemia + SHQ water (SHQ) group. The metabolites in urine were determined using ultra high performance liquid chromatography-triple-time of flight-mass spectrometry (UPLC/Triple-TOF MS). At the end of 1 month and 3 months, the total glyceride (TG) level was significantly lower in SHQ group compared to HL group. There was no significantly difference in total cholesterol (TC) levels in HL group compared with SHQ group. The results showed that dinking SHQ water can improve the TG, but with no effects on TC. After drinking SHQ water for 3 months, the rats in different groups could be classified into different clusters according to the metabolites in urine. Total 15 important metabolites were found and correlated with disturbance of amino acid, phospholipid, fatty acid and vitamin metabolism, which suggested the changes of metabolism in the body and possible mechanism by which SHQ improved the TG. These findings provide a new insight for the prevention and control of hyperlipidemia.

Relationship between Dry Eye Disease and Dyslipidemia: A Systematic Review.

Dyslipidemia has been suggested to be associated with the occurrence of dry eye disease (DED). However, whether dyslipidemia is responsible for the development of DED remains unclear. In this systematic review, we explored the relationship between DED and dyslipidemia by using quantitative data. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we conducted a comprehensive literature search in several databases, including PubMed, Embase, Cochrane Library, Web of Science, and Google Scholar, and obtained six relevant studies. Our findings indicated that the majority of the selected studies reported a statistically significant association between dyslipidemia and DED, particularly in women. However, our quantitative analysis revealed that only two studies reported statistically significant differences in total cholesterol and high-density lipoprotein cholesterol values. No statistically significant differences exist in the majority of lipid profile parameters between individuals with and without DED, but there is a statistically significant association between dyslipidemia and DED.

Analysis of Fecal Microbiota in Patients with Hypertension Complicated with Ischemic Stroke.

Ischemic stroke is a disease with a very high incidence in the clinic, and hypertension is the most important variable risk factor of ischemic stroke. Studies have shown that intestinal microbes are involved in the occurrence and development of various diseases. This study aims to explore whether intestinal microbes play an important role in the pathogenesis of ischemic stroke in a hypertensive population. In this study, the inpatients in the Department of Neurology and Cardiology of the Second Affiliated Hospital of Shandong First Medical University in April 2021 were selected, including seven patients with hypertension complicated with ischemic stroke and only seven patients with hypertension. After collecting the stool samples of patients, the gene sequence of the samples was detected by 16S rRNA sequencing technology, and the double-ended 2 × 150bp sequencing was carried out. After sequencing, the results were analyzed by diversity analysis, species difference analysis, species function difference analysis, and other bioinformatics tests. According to the test results, serum proteomics and biochemical blood tests were carried out to verify. There was no significant difference in α diversity and β diversity between hypertension complicated with the cerebral infarction and hypertension groups. LEfSe analysis showed that at the genus level, compared with the hypertension group, Bacteroides, UCG_009, and Eisenbergiella had significantly increased relative abundance. The genera with relatively significantly reduced abundance are Ruminococcus_gnavus_group, Sutterellaceae, Burkholderia, and Prevotella and the LDA score of Prevotella is < - 4, which indicates that there are significant differences. Compared with the blood biochemical indexes, the results showed that the level of APOA1 in hypertensive patients with ischemic stroke was significantly higher than that in hypertensive patients (p < 0.05), but there was no significant difference in total cholesterol (CHOL), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), apolipoprotein B (APOB), and free fatty acid (NEFA). Proteomic analysis showed that there were 89 up-regulated genes and 51 down-regulated genes in the serum of the two groups, and the expression of APOC2 and APOC3 in the cerebral infarction group with hypertension was significantly higher than that in the hypertension group (p < 0.05). The intestinal diversity of patients with hypertension complicated with stroke is similar to that of patients with hypertension, but there are differences in microbiota, among which Prevotella is the most significant. Prevotella could affect lipid metabolism so that APOC2 and APOC3 in the blood are significantly increased, leading to cerebral artery atherosclerosis and, finally, ischemic stroke. This provides a new idea for preventing and treating ischemic stroke in patients with hypertension, but the mechanism of Prevotella acting on apolipoprotein needs further verification by basic medical research.

Effects of Indonesian Shortfin Eel (Anguilla bicolor) By-Product Oil Supplementation on HOMA-IR and Lipid Profile in Obese Male Wistar Rats.

The prevalence of people being overweight and obese has increased globally over the past decades. The use of omega-3 fatty acids-a compound usually primarily found in fish oil-has been known to improve the metabolic profile of obese patients. As the demand for eels increases, the number of waste products from the eels increases and creates environmental problems. This study was conducted to investigate the effect of a newly discovered Indonesian Shortfin eel by-product oil supplementation on the Homeostasis Model Assessment-Estimated Insulin Resistance (HOMA-IR) and lipid profiles of obese male (Lee index ≥ 0.3) Wistar rats (Rattus norvegicus). The oil was extracted from waste products (heads). Fifteen obese rats were divided into three groups and were administered NaCl (C), commercial fish oil (CO), and Indonesian shortfin eel by-product oil (EO). All groups had statistically significant differences in total cholesterol, LDL, and triglyceride levels (p < 0.05). The CO and EO group showed a significant decrease in total cholesterol, LDL, and triglyceride after treatment. However, no significant difference was found in HDL levels and HOMA-IR. The supplementation of Indonesian shortfin eel by-product oil significantly improved lipid profile while effectively mitigating environmental challenges.

Relationship between atherogenic index of plasma and childhood asthma

To explore the relationship between atherogenic index of plasma (AIP) and childhood asthma. This retrospective study included 86 children with asthma admitted to the Changzhou Second People's Hospital Affiliated to Nanjing Medical University from July 2020 to August 2022 as the asthma group and 149 healthy children undergoing physical examination during the same period as the control group. Metabolic parameters including total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and blood glucose, as well as general information of the children such as height, weight, body mass index, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, and feeding history, were collected. Multivariable logistic regression analysis was used to study the relationship between AIP, triglycerides, and high-density lipoprotein cholesterol and asthma. The value of AIP, triglycerides, and high-density lipoprotein cholesterol for predicting asthma was assessed using receiver operating characteristic (ROC) curve analysis. The AIP and triglyceride levels in the asthma group were significantly higher than those in the control group, while high-density lipoprotein cholesterol was significantly lower (P<0.05). However, there was no significant difference in total cholesterol and low-density lipoprotein cholesterol between the two groups (P>0.05). Before and after adjusting for height, weight, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, feeding method, and blood glucose, multivariable logistic regression analysis showed that AIP, triglycerides, and high-density lipoprotein cholesterol were associated with asthma (P<0.05). ROC curve analysis showed that the optimal cutoff value for predicting asthma with AIP was -0.333, with a sensitivity of 80.2%, specificity of 55.0%, positive predictive value of 50.71%, and negative predictive value of 82.85%. The area under the curve (AUC) for AIP in predicting asthma was significantly higher than that for triglycerides (P=0.009), but there was no significant difference in AUC between AIP and high-density lipoprotein cholesterol (P=0.686). AIP, triglycerides, and high-density lipoprotein cholesterol are all associated with asthma. AIP has a higher value for predicting asthma than triglycerides and comparable value to high-density lipoprotein cholesterol.

Dyslipidemia in Muscular Dystrophy: A Systematic Review and Meta-Analysis.

Muscular dystrophies (MDs) are characterized by chronic muscle wasting but also poorly understood metabolic co-morbidities. We have recently shown that Duchenne MD (DMD) patients, dogs and asymptomatic carriers are affected by a new form of dyslipidemia that may exacerbate muscle damage. We aimed to perform a systematic review and meta-analysis for evidence that other types of MDs are associated with dyslipidemia compared to healthy controls. Search was conducted using MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials for reports that compare plasma/serum lipids from MD patients and controls, and meta-analysis of cross-sectional studies quantifying total cholesterol, high-density lipoprotein, low density lipoprotein and triglycerides was performed. Out of 749 studies, 17 met our inclusion criteria for meta-analysis. 14 of the 17 studies (82%) included investigated myotonic dystrophy (DM); other studies were on pseudohypertrophic MD (PMD) or DMD. As a whole, MD individuals had significantly higher levels of circulating total cholesterol (Hedges' g with 95% confidence interval [CI], 0.80 [0.03 - 1.56]; p = 0.04) and triglycerides (Hedges' g with 95% confidence interval [CI], 2.28[0.63 - 3.92]; p = 0.01) compared to controls. Meta-regression analysis showed the percentage of male gender was significantly associated with the difference in total cholesterol (beta = 0.05; 95% CI, - 0.02 to 0.11; p = 0.043) and high-density lipoprotein (beta = - 9.38; 95% CI, - 16.26 to - 2.50; p = 0.028). MD is associated with significantly higher circulating levels of total cholesterol and triglycerides. However, caution on the interpretation of these findings is warranted and future longitudinal research is required to better understand this relationship.

VITAMIN D SCREENING BEFORE FERTILITY TREATMENT PLANS: PILOT STUDY IN PCOS AND NON-PCOS INFERTILE WOMEN

Background: Polycystic ovarian syndrome (PCOS) and hypovitaminosis D are two most common endocrine disorders in young women leading to many adverse metabolic consequences. Objective of this study was to compare Vitamin D (VD) levels, Body Mass Index (BMI), lipid profile, hormonal parameters, and oocytes in PCOS and non-PCOS infertile females and to explore any association of VD levels with these parameters. Methods: This cross-sectional study was conducted from July 2019 to June 2020 after ethical approval at Aga Khan University in collaboration with Australian Concept of Infertility Medical Centre (ACIMC). It was conducted on 88 infertile females with age range 25–45 years recruited for Intracytoplasmic Sperm Injection (ICSI). Subjects were divided into two groups; PCOS (n=37) and non-PCOS (n=51) based on diagnostic criteria of PCOS. Serum VD was analyzed using ELISA. Statistical analysis was performed on SPSS-20. Mann-Whitney U-test and Spearman’s rank correlation were applied. Results: The mean BMI was significantly higher among PCOS as compared to non-PCOS women (p&lt;0.001). There were statistically significant differences in total cholesterol, triglycerides, Low Density Lipoprotein (LDL-C), High Density Lipoprotein (HDL-C), and Very Low Density Lipoprotein (VLDL) among groups (p&lt;0.05). There was significant correlation of vitamin D with maturity of oocytes (r=0.836, p&lt;0.0001). Conclusion: The findings indicated that PCOs women were obese, had abnormal lipid profile with low VD levels. Low levels of VD were associated with poor maturity of oocytes which is required for successful conception. Pak J Pysiol 2023;19(2):15–9

CHARACTERISTICS OF DYSLIPIDEMIA IN THE CROATIAN RURAL AREA DAMAGED BY AN EARTHQUAKE. “THE SILENT KILLER HUNT” - CROATIAN SOCIETY OF HYPERTENSION PROJECT

Objective: Dyslipidemia is one of the most prevalent cardiovascular risk factors, making its detection and control essential due to the risk of serious complications. Prevention and sensible management of dyslipidemia can markedly alter cardiovascular morbidity and mortality. This study aimed to determine the prevalence of dyslipidemia among the adult population in a rural part of Croatia seriously damaged by the earthquake and evaluate the gender-associated differences in lipid profiles. Design and method: Blood samples of 244 subjects (188 women) (opportunistic screening) were collected under fasting conditions. The bloodwork results were analyzed using descriptive statistics and t-tests were used for checking differences between the sexes. Results: The average age of the whole group was 61.9 ± 14.3 years. Prevalence of hypercholesterolemia, hypertriglyceridemia, elevated LDL cholesterol levels and low HDL cholesterol levels were 59.0%, 34.8%, 57.0%, and 32.0%, respectively. Average values of total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol were 5.4 ± 1.7mmol/l, triglyceride 1.8 ± 1.1 mmol/l, 1.4 ± 0.3 mmol/l, and 3.3 ± 1.02 mmol/l. We failed to find a significant difference in total cholesterol and LDL cholesterol between men and women (p&gt;0.05). There was a statistically significant difference in triglyceride and HDL cholesterol levels between men and women with men showing higher levels of triglycerides (t = 2.08, p&lt;0.05) and lower levels of HDL cholesterol (t = -4.1, p&lt;0.05) than women. Conclusions: The prevalence of dyslipidemia in this rural area is high, higher than in other rural parts of Croatia indicating that stressful life after the earthquake and an unhealthy diet might contribute to this. Primary prevention i.e. education and regular examination of this vulnerable population should be in focus and even more intensive than in other rural, remote areas.

Long-term changes in serum levels of lipoproteins in children and adolescents with attention-deficit/hyperactivity disorder (ADHD)

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder affecting approximately 5% of children worldwide. The causal mechanisms of ADHD remain unclear as the aetiology of this disorder seems to be multifactorial. One research field addresses the impact on lipid metabolism and particularly serum lipid fractions on the development of ADHD symptoms. This post hoc analysis aimed to investigate long-term changes in serum levels of lipoproteins in children and adolescents with ADHD and controls. Data of German children and adolescents from the nationwide and representative “Kinder- und Jugendgesundheitssurvey (KiGGS)” study were analysed at baseline and at a ten-year follow-up. At the two time points, participants in the control group were compared with those in the ADHD group, both before and after propensity score matching. Differences in total cholesterol, low-density lipoproteins (LDL), high-density lipoproteins (HDL) and triglycerides were assessed between matched children with and without ADHD. In addition, subgroups with versus without methylphenidate use were compared at both time points. At baseline before matching, there were no significant differences for lipid parameters between participants in the ADHD group (n = 1,219) and the control group (n = 9,741): total cholesterol (Exp(ß) = 0.999, 95%-CI 0.911–1.094, p = .979), LDL (Exp(ß) = 0.967, 95%-CI 0.872–1.071, p = .525), HDL (Exp(ß) = 1.095, 95%-CI 0.899–1.331, p = .366) and triglycerides (Exp(ß) = 1.038, 95%-CI 0.948–1.133, p = .412). Propensity score matching confirmed the non-significant differences between the ADHD and non-ADHD group at baseline. At the 10-year follow-up, n = 571 participants fulfilled complete inclusion criteria, among them 268 subjects were classified as ADHD. The two groups did not significantly differ in lipid fractions, neither cross-sectionally nor with regard to long-term changes. There was also no significant difference between methylphenidate subgroups. In this sample of children and adolescents we could not reveal any significant associations between serum lipid fractions and the diagnosis of ADHD, neither cross-sectionally nor longitudinally; even when methylphenidate use was considered. Thus, further studies using larger sample sizes are required to investigate putative long-term changes in serum lipid fractions related to ADHD.
