Association of lipid profile with primary open angle glaucoma in non-obese patients

Hyperlipidemia has been shown to be associated with Glaucoma as well as increased intra ocular pressure (IOP). We conducted a case control study to further study the association of Lipid profile with Primary Open Angle Glaucoma (POAG) in non-obese patients.: With the approval from Institutional Ethics Committee (ICE) and written informed consent, 100 adult patients were included in the case control study. The methods applied in the study adhered to the tenets of the declaration of Helsinki. 50 non-obese POAG patients of above 40 years aged were included as cases and another 50 without Glaucoma were taken as controls. Patients were further subjected to biochemical investigation of the serum lipid profile performed by Vitros 5600.: Mean total cholesterol, triglyceride and low-density lipoprotein (LDL) levels were found to be significantly higher in non-obese POAG cases as compared to that in controls (p<0.05), whereas mean high density lipoprotein (HDL) levels were significantly lower in non-obese POAG cases as compared to that in controls (p<0.001). The odds of high cholesterol levels to be associated with POAG in non-obese are statistically significant (p<0.001).: The study demonstrated a relationship of serum lipid levels with risk of primary open angle glaucoma.

Variability in Lipid Profiles During Young Adulthood and the Risk of Coronary Artery Calcium Incidence in Midlife: Insights From the CARDIA Study.

Intraindividual variability in lipid profiles is recognized as a potential predictor of cardiovascular events. However, the influence of early adulthood lipid profile variability along with mean lipid levels on future coronary artery calcium (CAC) incidence remains unclear. A total of 2395 participants (41.6% men; mean±SD age, 40.2±3.6 years) with initial CAC =0 from the CARDIA study (Coronary Artery Risk Development in Young Adults) were included. Serial lipid measurements were obtained to calculate mean levels and variability of total cholesterol, low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), and triglycerides. CAC incidence was defined as CAC >0 at follow-up. During a mean follow-up of 9.0 years, 534 individuals (22.3%) exhibited CAC incidence. Higher mean levels of total cholesterol, LDL-C, and non-HDL-C were associated with a greater risk of future CAC incidence. Similarly, 1-SD increment of lipid variability, as assessed by variability independent of the mean, was associated with an increased risk of CAC incidence (LDL-C: hazard ratio, 1.139 [95% CI, 1.048-1.238]; P=0.002; non-HDL-C: hazard ratio, 1.102 [95% CI, 1.014-1.198]; P=0.022; and triglycerides: hazard ratio, 1.480 [95% CI, 1.384-1.582]; P<0.001). Combination analyses demonstrated that participants with both high lipid levels and high variability in lipid profiles (LDL-C and non-HDL-C) faced the greatest risk of CAC incidence. Specifically, elevated variability of LDL-C was associated with an additional risk of CAC incidence even in low mean levels of LDL-C (hazard ratio, 1.396 [95% CI, 1.106-1.763]; P=0.005). These findings remained robust across a series of sensitivity and subgroup analyses. Elevated variability in LDL-C and non-HDL-C during young adulthood was associated with an increased risk of CAC incidence in midlife, especially among those with high mean levels of atherogenic lipoproteins. These findings highlight the importance of maintaining consistently low levels of atherogenic lipids throughout early adulthood to reduce subclinical atherosclerosis in midlife.

Alterations in Serum Lipids and Lipoproteins Induced by Neoadjuvant Chemotherapy in Patients with Osteosarcoma around the Knee Joint: A Retrospective Analysis.

To investigate the serum lipid profiles of patients with localized osteosarcoma around the knee joint before and after neoadjuvant chemotherapy. After retrospectively screening the data of 742 patients between January 2007 and July 2020, 50 patients aged 13 to 39 years with Enneking stage II disease were included in the study. Serum lipid levels, including total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), lipoprotein-α [Lp(a)], and apolipoprotein A1, B, and E (ApoA1, ApoB, and ApoE), and clinicopathological characteristics were collected before and after neoadjuvant chemotherapy. The mean levels of TC, TG, and ApoB were significantly increased following neoadjuvant chemotherapy (16%, 38%, and 20%, respectively, vs. pretreatment values; P<0.01). The mean levels of LDL-C and ApoE were also 19% and 16% higher, respectively (P<0.05). No correlation was found between the pretreatment lipid profile and the histologic response to chemotherapy. An increase in Lp(a) was strongly correlated with the Ki-67 index (R=0.31, P=0.023). Moreover, a trend toward longer disease-free survival (DFS) was observed in patients with decreased TG and increased LDL-C following chemotherapy, although this difference was not statistically significant (P=0.23 and P=0.24, respectively). Significant elevations in serum lipids were observed after neoadjuvant chemotherapy in patients with localized osteosarcoma. There was no prognostic significance of pretreatment serum lipid levels on histologic response to neoadjuvant chemotherapy. The scale of increase in serum Lp(a) might have a potential prognostic role in osteosarcoma. Patients with increased LDL-C or reduced TG after chemotherapy seem to exhibit a trend toward favorable DFS.

Assessment of Serum Lipid Profile Among Patients With Hemorrhagic Versus Ischemic Strokes at Muzaffarabad; A Comparative Study

Objective: To assess the serum lipid level in adults with hemorrhagic versus ischemic stroke and determine the associated factors. Methodology: A Comparative cross-sectional study was conducted at the Department of General Medicine, Combined Military Hospital Muzaffarabad, Azad Kashmir from 30-3-2020 to 30-9-2020. Out of 100 patients were enrolled and divided into two different groups. 3ml of blood was drawn and sent for fasting lipid profile to the single institutional laboratory. The blood samples were analyzed enzymatically using an autoanalyzer. All the obtained information was analyzed using SPSS. Results: In ischemic stroke patients, the mean TC was 227.20±16.47 mg/dl; among hemorrhagic stroke patients, mean total cholesterol levels were 203.5 ±16.8 with the value of P=&lt;0.001. The Total mean HDL was found 36.10±4.29 with a value of p=&lt;0.001. In ischemic stroke patients, the mean LDL was 145.18±16.98; in hemorrhagic stroke patients, the mean LDL was 131.96±12.12 (p-value=&lt;0.001). In ischemic stroke patients, the mean TG was 203.18±57.74 mg/dl while in hemorrhagic stroke patients, the mean TG was 164.67±53.25 with a value of p=0.001) Conclusion: This study concluded that the mean TC, HDL, LDL, and TG of the patients was 215±20.42 mg/dl, 37.77±4.47 mg/dl, t 138.57±16.11 mg/dl, and 183.93±58.55 mg/dl respectively. This study further concluded that is substantial correlation exists between the serum lipid profile of adults and the type of stroke

E056 Particularities of the lipid profile in rheumatoid arthritis

Abstract Background/Aims Rheumatoid arthritis (RA), like all autoimmune diseases, is associated with a high cardiovascular risk. This risk is essentially linked to the chronic inflammation and dyslipidaemia engendered by this chronic inflammatory rheumatism. The objective of this work was to study the particularities of the lipid profile in RA. Methods We conducted a retrospective study including patients with RA according to ACR- EULAR 2010 criteria, followed in an internal medicine department between 2015 and 2022. Lipid profile data (total cholesterol (TC), high-density lipoproteins (HDLc), low-density lipoproteins (LDLc), and triglycerides (TG)) were collected. Results Eighty patients with RA were studied. The mean age was 60.79 years [range 30-91]. The sex ratio (F/H) was 4.33, with a clear female predominance. The mean age of disease onset was 46.34 years [extremes: 22-82]. A personal history of dyslipidaemia was noted in 19 patients: hypercholesterolemia, hypertriglyceridemia, and mixed dyslipidaemia were found in 8, 4 and 7 cases. Other comorbidities were arterial hypertension in 35% of cases (n = 28), diabetes in 30% of cases (n = 24), renal insufficiency in 6.25% of cases (n = 5) and a cardiovascular accident in 5% of cases (n = 4). Obesity was present in 15% of patients and smoking in 5%. 69 patients had a lipid panel. Dyslipidaemia was present in 66.7% of cases (n = 46). The mean TC level was 4.47 ± 1.0 mmol/L [range: 2.32 - 6.96 mmol/L], the mean TG level was 2.64 ± 0.81 [range: 0.90 - 4 mmol/L], the mean HDLc level was 1.106 ± 0.394 mmol/L [0.50 - 2] and the mean LDLc level was 1.38 ± 0.565 mmol/L [0.56 - 3.59 mmol/L]. Hypercholesterolemia (21.3%) and hypocholesterolaemia (21.3%) were the most common lipid abnormalities. Hypertriglyceridemia was observed in 10% of cases (n = 8). A low HDLc was observed in 20% of cases (n = 16). Only one patient had a high HDLc, with HDLc= 2 mmol/l. A low LDL was present in 10% of cases (n = 8). Conclusion In our study, hypolipidemia was the most common dyslipidaemia. This confirms the lipid paradox found in RA. Indeed, systemic inflammation is responsible for quantitative and qualitative alterations in lipoproteins. Stabilization of the disease leads to normalization of the lipid balance and improved control of cardiovascular risk. Disclosure I. Fenniche: None. M. Somai: None. I. Rachdi: None. I. Arbaoui: None.

Distal Upper Extremity Arterial Calcification as a Predictor for Subclinical Coronary Artery Disease by Coronary Artery Calcium Scoring.

Several studies have linked calcification of the thoracic and lower extremity arterial trunks to an increased risk of developing coronary artery disease (CAD). Calcifications of the radial and/or ulnar artery are regularly identified in hand/wrist x-rays; however, the clinical relevance of these findings as related to identifying subclinical CAD is not well understood. Associations between CAD and upper extremity calcifications have been reported, but the timeline is unclear. The purpose of this study was to evaluate the association between upper extremity arterial calcifications on hand radiographs with CAD by coronary artery calcification (CAC) scoring in patients with no known history of CAD. This is a pilot single-center, prospective, matched cohort study. We included patients with no known history of CAD, related symptoms, or major risk factors. We recruited five patients with calcifications (cal+) and five patients matched by age, race, sex, and medical history but without calcifications (cal-). CAC scores were determined from computed tomography scanning, and lipid profile was evaluated. In the cal+ group, the mean CAC total score was 244.1; in the control (cal-) group, it was 85.2. The mean total cholesterol levels were 220.8 mg per dL and 167 mg per dL in the cal+ and cal- groups, respectively. Two cal+ patients with CAC scores of 937 and 669 died shortly after being enrolled in our study. Preliminary findings suggest that calcifications in the radial or ulnar artery in otherwise asymptomatic patients with no history of CAD may be an independent sign of CAD.

Abstract P505: Investigating Sudden Death in a Large North Carolina County: Methods and Findings of a Population-Based Registry

Introduction: Evidence on drivers of sudden death (SD) is needed to understand its persistently high incidence and inform prevention interventions. SD studies have been hampered by data limitations and restrictive SD criteria. We conducted a population-based study of all-cause, out-of-hospital SD using Emergency Medical Services (EMS) data from Wake County, a large North Carolina county with &gt;1 million residents. Methods: We screened EMS records of out-of-hospital deaths between 2013-2015 among persons aged 18-64 years, collected medical and death records, and adjudicated 399 SD cases according to a standardized protocol. Deaths occurring in hospices or nursing homes were excluded, as were those due to unnatural death or cancer. Deaths were not excluded by time last seen or coronary artery disease (CAD) criteria. Frequency matched living controls were identified from the same county and time. We compiled and summarized findings based on peer-reviewed papers and published abstracts in Table 1. Results: Cardiovascular disease risk factors were common among decedents, including hypertension (60.4%, 244 of 371), though only 14.8% (55 of 371) had documented CAD. SD cases had lower adjusted mean total cholesterol, low-density lipoprotein and high-density lipoprotein levels compared to controls. Furthermore, left ventricular hypertrophy and inflammation suggested nodes on a common causal pathway. Poor health care management was frequent as well as mental health and substance use problems. Environmental factors such as poverty, air pollution and absence of nearby greenways were associated with SD. Conclusions: Conducting a population-based registry of adjudicated SD cases was feasible and provided high quality data for study. Our findings suggest that SD is not only tied to CAD but a syndrome with potentially different environmental and inflammatory etiologies. Future studies should investigate modifiable risk factors for interventions to prevent SD.

Evaluation of Hyperlipidemia in Patients with Gallstones

Introduction: Gallstone disease is one of the biggest global public health problems. The most common complications associated with gallstone disease include cholecystitis, pancreatitis, and cholangitis. The current study aimed to show that serum lipids have a significant role in the etiology of cholelithiasis. Methods: Before surgery, all patients had blood samples taken. Lipid profile tests including very low-density lipoprotein cholesterol (VLDL-C), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), and total cholesterol (TC) were performed on the serum, which was collected using standard procedures. Results: The results showed that mean serum lipid levels were significantly different (P&lt;0.001) between the patients and the control group. In addition, the study revealed statistically significant differences between the genders (P&lt;0.001); in other words, significant differences were found between males and females in patients and controls in mean serum TC, HDL, and TG levels. On the other hand, the findings of the study indicated a notable rise (P&lt;0.001) in serum TC, triglyceride, and HDL levels in the age category 40-59 years, followed by the age category≥60 years and the age category 29-39 years. Conclusion: Overall, changes in serum lipid profile are a possible consequence of the presence of gallstones; in other words, serum TC, HDL, and TG levels were significantly higher in patients with gallstone disease compared to the control group.

Association between organophosphate flame retardant exposure and lipid metabolism: data from the 2013-2014 National Health and Nutrition Examination Survey.

Organophosphate flame retardants (OPFRs) are emerging environmental pollutants that can be detected in water, dust, and biological organisms. Certain OPFRs can disrupt lipid metabolism in animal models and cell lines. However, the effects of OPFRs on human lipid metabolism remain unclear. We included 1,580 participants (≥20 years) from the 2013-2014 National Health and Nutrition Examination Survey (NHANES) to explore the relationship between OPFR exposure and lipid metabolism biomarkers. After adjusting for confounding factors, results showed that one-unit increases in the log levels of diphenyl phosphate (DPhP) (regression coefficient = -5.755; S.E. = 2.289; p = 0.023) and log bis-(1-chloro-2-propyl) phosphate (BCPP) (regression coefficient = -4.637; S.E. = 2.019; p = 0.036) were negatively associated with the levels of total cholesterol (TC) in all participants. One-unit increases in the levels of DPhP (regression coefficient = -2.292; S.E. = 0.802; p = 0.012), log bis (1,3-dichloro-2-propyl) phosphate (BDCPP) (regression coefficient = -2.046; S.E. = 0.825; p = 0.026), and log bis-2-chloroethyl phosphate (BCEP) (regression coefficient = -2.604; S.E. = 0.704; p = 0.002) were negatively associated with the levels of high-density lipoprotein cholesterol (HDL-C). With increasing quartiles of urine BDCPP levels, the mean TC levels significantly decreased in all participants (p value for trend = 0.028), and quartile increases in the levels of DPhP (p value for trend = 0.01), BDCPP (p value for trend = 0.001), and BCEP (p value for trend<0.001) were negatively corelated with HDL-C, with approximately 5.9, 9.9, and 12.5% differences between the upper and lower quartiles. In conclusion, DPhP, BDCPP, and BCEP were negatively related to HDL-C concentration, whereas DPhP and BCPP levels were negatively associated with TC level. Thus, exposure to OPFRs may interfere with lipid metabolism.

Atherogenic Index, Cardiovascular Risk Ratio, and Atherogenic Coefficient as Risk Factors for Cardiovascular Disease in Pre-eclampsia in Southeast Nigeria: A Cross-Sectional Study.

Pre-eclampsia is a key trigger for maternal and perinatal morbidity and mortality. Current evidence suggests an association between dyslipidemia and atherosclerosis. Thus, the importance of evaluating some indices of atherosclerosis during pregnancy cannot be over-emphasized. To evaluate the effect of some lipid profile indices as risk factors for developing cardiovascular disease (CVD) among women with pre-eclampsia in Enugu, Southeast Nigeria. A cross-sectional study of two groups of eligible pregnant women between 20 and 40 weeks of gestation selected at three healthcare facilities in Enugu, Nigeria was carried out. The case group consisted of 160 women with pre-eclampsia, while the control group consisted of 160 normotensive pregnant women. Participants' fasting blood samples were analyzed for different fractions of lipids and their atherogenic indices were calculated. There were significantly higher mean levels of total cholesterol (TC), low-density lipoprotein (LDL), and triglyceride (TG) [P < 0.001] in pre-eclampsia than in normal pregnancy. The atherogenic index of plasma (AIP), cardiovascular risk ratio (CRR), and atherogenic coefficient (AC) were significantly higher in pre-eclampsia than in normal pregnancy (P < 0.001) and there was a significant positive correlation between mean arterial pressure (MAP) and AIP (r = 0.421), CRR (r = 0.416) and AC (r = 0.634) for women with pre-eclampsia. Pre-eclampsia is associated with an increased risk of CVDs. Determining the atherogenic indices and assessing the AIP level in pre-eclamptic women may predict disease risk and help in early management and measures for its prevention.

Exploring Serum Lipid Profile Changes in Patients During Laparoscopic Choecystectomy

Background: For quite some time, cholecystectomy has been perceived as a safe surgical procedure, often with limited attention given to potential secondary effects. It's worth noting that the gallbladder plays a significant role as a regulatory component in coordination with vital metabolic pathways responsible for maintaining equilibrium in the body. When the gallbladder is removed, bile from the liver flows directly into the upper portion of the intestine. Therefore, this study aims to evaluate the impact of laparoscopic cholecystectomy on the serum lipid profile of patients. Material and methods: A total of 60 patients diagnosed with gallstones were enrolled in this study. Preoperative blood samples were collected from all patients under sterile conditions, two hours prior to their scheduled surgery, to evaluate their lipid profile. Results: The preoperative mean Total Cholesterol (TC) levels were measured at 160.5 mg%, while postoperatively, they showed a slight decrease to 150.8 mg%. Similarly, the mean High-Density Lipoprotein Cholesterol (HDL-C) levels before surgery were 42.1 mg%, and they decreased to 40.8 mg% after the procedure. In contrast, the mean Triglyceride (TG) levels saw an increase from 180.8 mg% preoperatively to 200.8 mg% postoperatively. Notably, the comparison of mean TC and TG levels before and after the surgery yielded significant results, indicating changes in these lipid parameters following laparoscopic cholecystectomy. Conclusion: Patients undergoing laparoscopic cholecystectomy experience noteworthy changes in their serum lipid profile.

Abstract C087: Association of serum lipid profile with prostate cancer risk and aggressiveness in Nigerian men

Abstract OBJECTIVE Though prostate cancer (PCa) is the most common cancer and cause of cancer death among Nigerian men, its relationship with serum lipid profiles, a biochemical measurement of dietary fat, has not been explored among Nigerian men. The study aimed to determine the association of serum lipid profile with prostate cancer risk and aggressiveness. METHODS The study was a case-control conducted at University College Hospital, Ibadan, Nigeria. The cases were newly diagnosed prostate cancer patients ages 50-75 years, while the controls were age-matched healthy men with confirmed normal PSA. Participants with uncontrolled comorbidities, poor performance status (ECOG ≥3), and weight loss in the past month were not eligible. The patient characteristics (age, marital status, employment status, highest level of education, high-fat diet, lack of exercise, tobacco smoking, alcohol intake, family history of prostate cancer, comorbidities, and tumor characteristics [PSA at presentation, histology, Gleason score, and stage at presentation] in the cases alone) were collected using an interviewer-administered questionnaire. A serum lipid profile test (including total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) was done in all participants. Analysis of the variables was on SPSS version 23.0, with a t-test to compare the serum lipid profile between the case and control groups, a chi-square to compare the sociodemographic and patient characteristics between both groups and an ANOVA test to determine the association between serum lipid profile and Gleason's score (disease grade) or stage of prostate cancer. RESULTS Enrolled in each group were seventy-four participants. The mean age ± standard deviation was 65.0 ± 5.9 years for cases and 63.0 ± 6.5 years for controls. Participants with a high-fat diet (p = 0.006), physical inactivity (p = 0.046), alcohol consumption (p = 0.005), and family history (p = 0.002) were significantly higher in the case group than the controls. A high proportion of the cases had high-grade disease (GS ≥ 8) [39.2%] and stage 4 disease (35.2%). The mean levels of TC (p&amp;lt;0.001) and HDL-C (p&amp;lt;0.001) were significantly higher in the cases. The mean TG increased while HDL-C decreased as the disease stage advanced but with no statistical significance. While the mean TC (p = 0.001) increased significantly with worsening prostate cancer grade, the mean HDL-C was highest in low-grade disease (p &amp;lt;0.001). CONCLUSION Elevated total cholesterol and high-density lipoprotein cholesterol were associated with increased prostate cancer risk. While elevated total cholesterol was associated with high-grade prostate cancer, a high level of high-density lipoprotein cholesterol was associated with the low-grade disease. Hence, regular serum lipid profile tests may be encouraged among Nigerian men for early detection and treatment of any cholesterol derangement to avoid its predisposition to prostate cancer.

Cardiovascular risk factors among Polish employees of uniformed services.

Employees of uniformed services (EoUS) were screened for cardiovascular risk factors. A total of 1138 EoUS (age M±SD 49.9±6.0 years) and 263 controls (age M±SD 54.4±9.7 years) under the care of the cardiology clinic in Gdańsk, Poland, were included in the study. Medical history and blood samples were collected, and a physical examination was performed. Ten-year cardiovascular risk of death was calculated using the systematic coronary risk evaluation (SCORE) risk algorithm for high-risk countries. Significantly higher values of mean systolic and mean diastolic blood pressure, mean total cholesterol level and mean BMI were recorded among the EoUS compared to controls (M±SD 141.7±11.6 mm Hg vs. 135.5±11.0 mm Hg, p < 0.001; 90.1±5.9 mm Hg vs. 84.5±6.8 mm Hg, p < 0.001; 6.01±0.76 mmol vs. 5.44±0.87 mmol, p < 0.001; 29.3±4.7 vs. 29.0±4.1, p < 0.001, respectively). Smoking cigarettes was most frequently reported by the youngest group (20-39 years old) - 47.7% and it was significantly higher in the entire EoUS group compared to control group (35.5% vs. 16.7%, p = 0.001). The occurrence of observed risk factors (blood pressure ≥140/90 mm Hg, total cholesterol concentration >5 mmol, smoking,) was significantly higher among EoUS compared to controls (92.1% vs. 57.8%, p < 0.001; 89.0% vs. 66.9%, p < 0.001; 35.5% vs. 16.7%, p < 0.001, respectively). In the male group, the mean calculated ten-year risk of fatal cardiovascular events, the percentage of high calculated risk, and very high risk were higher in the EoUS group compared to controls (M±SD 4.44±3.49 vs. 4.23±3.86, p = 0.001; 23.7% vs. 20.2%, p = 0.007; 7.4% vs. 6.5%, p = 0.03, respectively). The prevalence of all identified risk factors was found to be higher among employees of uniformed services when compared to the control group. The presence of these risk factors within the population of uniformed service employees results in a greater risk of mortality from cardiovascular diseases.

High diet quality indices associated with lower risk of lipid profile abnormalities in Taiwanese kidney transplant recipients

Cardiovascular disease (CVD) and its risk factors seem to be linked with deteriorated graft function and persists as the major cause of mortality in kidney transplant recipients (KTRs). Diet quality is associated with CVD prevention in the healthy population, however, less study focuses on KTRs. The study aimed to determine the association between diet quality indices and lipid profile abnormalities as risk factors for CVD in KTRs. This prospective study enrolled 106 KTRs who had functioning allografts from September 2016. Lipid profiles included low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), and triglyceride (TG) and were based on the National Cholesterol Education Program Adult Treatment Panel III recommendations. Three-day dietary data were collected by a well-trained registered dietitian. The Alternative Healthy Eating Index-Taiwan (AHEI-Taiwan), Alternative Healthy Eating Index-2010 (AHEI-2010), and Healthy Eating Index-2015 (HEI-2015) scores were calculated and divided into quartiles and compared accordingly. KTRs’ mean LDL-C, HDL-C, TC, and TG levels were 119.8 ± 36.6 mg/dL, 52.0 ± 17.9 mg/dL, 205.8 ± 43.9 mg/dL, and 160.2 ± 121.6 mg/dL, respectively. Compared with the lowest quartile, only the highest quartile of AHEI-Taiwan had lower TC and LDL-C levels. After adjustment for age, gender, energy, Charlson comorbidity index, transplant duration, and dialysis duration, logistic regression analysis revealed that the highest quartile of AHEI-Taiwan had 82% (odds ratio [OR], 0.18; 95% confidence interval [CI] 0.04–0.72, p < 0.05) lower odds of high TC and 88% (OR 0.12; 95% CI 0.03–0.58, p < 0.05) lower odds of high LDL-C, and the highest quartile of HEI-2015 had 77% (OR 0.23; 95% CI 0.05–0.95, p < 0.05) lower odds of high LDL-C. Higher adherence to a healthy diet as per AHEI-Taiwan and HEI-2015 guidelines associated with lower risk of lipid profile abnormalities in KTRs.

Sex differences in cholesterol and triglyceride levels among hospitalized adolescents and young adults with eating disorders.

To determine sex differences in cholesterol and triglyceride levels among adolescents and young adults hospitalized for medical complications of eating disorders. A retrospective electronic medical record review of patients aged 9-25 years admitted to the University of California, San Francisco Eating Disorders Program for medical stabilization, between 2012 and 2020, was conducted. Non-fasting total cholesterol and triglycerides were collected; however, LDL and HDL levels were not available. Among 83 males and 441 females, mean ± SD age was 15.5 ± 2.8 years, 64.1% had anorexia nervosa, and admission percent median body mass index was 87.3 ± 13.9. The proportion of males and females with high total cholesterol (13.3% vs. 18.1%, Cramer's V = 0.05, p = .28) and high triglyceride levels (9.6% vs. 8.1%, Cramer's V = 0.02, p = .63) did not differ. Mean total cholesterol levels were higher in females compared to males (F 169.6 ± 41.1 mg/dL vs. M 154.5 ± 45.1 mg/dL, Cohen's d = 0.36, p = .003), although a majority were within the normal range. In adjusted linear regression models, male (compared to female) sex (B = -14.40, 95% CI -24.54, -4.27) and higher percent median body mass index (B = -0.33, 95% CI -0.60, -0.06) were associated with lower total cholesterol levels in adjusted models (R2 = 0.04). Building on prior work showing equally severe complications of eating disorders in males compared to females, we did not find sex differences in those presenting with high total cholesterol or triglycerides. Future research is needed to understand the pathophysiology and role of dyslipidemia in acute malnutrition, and the impact of nutritional rehabilitation and weight restoration. We found that the proportion of male and female adolescents and young adults hospitalized for medical complications of an eating disorder with high total cholesterol did not significantly differ. Although average total cholesterol levels were higher in female compared to male patients with eating disorders, a majority of these levels remained within the normal range. Patients with more severe malnutrition had a higher risk of elevated total cholesterol levels. Clinicians should consider monitoring cholesterol levels in young people hospitalized for restrictive eating disorders.

Thyroid Profile and Serum Lipid Level in Women with Normal Pregnancy

Objective: To evaluate the changes in thyroid profile and serum lipid level in normal pregnancy.Methods: This observational study was conducted at the Department of Biochemistry of Santosh Medical College, Ghaziabad, UP, India, from June 2021 to February 2022. In this study, 200 average pregnant women were enrolled. The thyroid profile was estimated using the ELISA method, and the lipid profile was measured using the enzymatic kit method. All data were expressed as means and standard deviations, and SPSS version 17 was used for statistical analysis.Results: This observational study observed that the mean T3, T4, and TSH levels increased significantly in the second trimester compared to the first trimester. In contrast, the mean value of T3, T4, and TSH decreased in the third trimester as compared to the second trimester. The mean levels of total cholesterol, triglyceride, and LDL-cholesterol increased significantly, while the mean value of HDL-cholesterol decreased significantly in the second and third trimesters when compared to the first trimester.Conclusion: This study demonstrated abnormal lipid and thyroid metabolism. Changes in thyroid profile may be associated with adverse obstetric outcomes. The altered lipid parameters, mainly High TG and low HDL-C concentrations, may promote vascular dysfunction and oxidative stress.

Comparison of umbilical cord blood lipid profiles between appropriate and small for gestational age newborns with their mothers’ lipid profiles: a case-control study from tertiary care centre of Karnataka

Background: Fetal malnutrition and fetal growth restriction results in dysfunctions of neuroendocrine system, pancreas and adipose-tissue; finally increasing the food intake and decreasing energy use. This results in an increase in adipose deposition and insulin-resistance and ultimately increasing chances of adult metabolic-diseases. This study makes an effort to compare and contrast the lipid-profiles of Small for Gestational Age (SGA) and Appropriate for Gestational Age (AGA)newborns correlating and with their mother’s lipid-profiles. Methods: This was a case-control study, conducted in the Departments of Pediatrics and OBG of Karwar Institute of Medical Sciences,Karwar, Karnataka,India over a period of twelve months(January-2021 to January-2022). With 500neonates, 357appropriate for gestational age (AGA) and 143 small for gestational age(SGA) babies were included for the study as controls and cases for their lipid profiles using their cord-blood. Results: here, we found that SGA-babies had lower gestational age (37.40±1.01 weeks) at birth compared to AGA-babies (39.22±1.05 weeks) which was statistically significant. The mean Total Cholesterol (TC) level (84.47±27.39 mg/dl) was higher in SGA-babies compared to AGA-babies (56.87±32.28 mg/dl) and this difference was statistically highly significant (p value&lt;0.0001). The mean very low density lipoprotein (VLDL) level (14.10±10.67 mg/dl) was higher in SGA-babies than AGA-babies (7.17±3.69 mg/dl) with p value&lt;0.0001 (highly significant). The mean low density lipoprotein (LDL) level (38.74±19.85 mg/dl) was higher in SGA-babies compared to AGA-babies (25.63±14.15 mg/dl) and this difference was statistically significant (p value&lt;0.0001). The mean high density lipoprotein (HDL) levels of AGA and SGA-babies were comparable with low statistical significance (26.70±14.90 mg/dl of SGA; 24.45±9.567 mg/dl of AGA, p value 0.095). Conclusions: Levels of all lipids were observed to be higher in SGA babies than in AGA babies. Mothers who gave birth to SGA babies were found to have statistically significant high VLDL levels.

The Role of the Low-Density Lipoprotein/High-Density Lipoprotein Cholesterol Ratio as an Atherogenic Risk Factor in Young Adults with Ischemic Stroke: A Case-Control Study.

Dyslipidemia is a major atherogenic risk factor for ischemic stroke. Stroke patients tend to have high levels of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) and low levels of high-density lipoprotein cholesterol (HDL-C). Therefore, it is noteworthy that there has been an increase in ischemic stroke cases in young and elderly individuals in recent years. This study investigated the TC/HDL-C ratio and the LDL-C/HDL-C ratio, which may be more specific and common lipid parameters in young patients with ischemic stroke. This study aimed to demonstrate the sensitivity and specificity of TC/HDL-C and LDL-C/HDL-C ratios as atherogenic markers for young adult ischemic strokes. This trial was conducted as a retrospective case-control study. A total of 123 patients (patient group) and 86 healthy individuals (control group) aged 18-50 years were randomly selected from four different hospitals. Lipid parameters and TC/HDL-C and LDL-C/HDL-C ratios were compared between these two groups. The mean age was 38.8 ± 7.3 years in patients and 37.7 ± 9 years in controls (p > 005). The HDL-C levels were 39.1 ± 10.8 mg/dL in patients and 48.4 ± 13.8 mg/dL in controls (p < 0.001). LDL-C/HDL-C ratios were 3.23 ± 1.74 and 2.38 ± 0.87, and TC/HDL-C ratios were 5.24 ± 2.31 and 4.10 ± 1.25 in the patient and control groups, respectively (p < 0.001). The LDL-C/HDL-C and TC/HDL-C cutoff values in ROC analyses were 2.61 and 4.40 respectively; the AUCs (95% CI) were determined to be 0.680 (0.608-0.753) and 0.683 (0.610-0.755) (p < 0.001), respectively. An increased risk of stroke was observed in those with a high LDL-C/HDL-C ratio (OR = 1.827; 95% CI = 1.341-2.488; p < 0.001). Our study obtained similar results when we compared the mean TC and LDL-C levels between the two groups. However, considering the TC/HDL-C and LDL-C/HDL-C ratios, it is noteworthy that there was a significant difference between the patient and control groups.

Cord blood triglyceride and total cholesterol in preterm and term neonates: reference values and associated factors from the Japan Environment and Children's Study.

This study aimed to investigate the associations between cord serum total cholesterol (TC) and triglyceride (TG)levels and perinatal factors and determine the reference levels of cord blood TC and TG in Japanese neonates. This was a prospective birth cohort study using data from the Japan Environment and Children's Study, which included data on births from 2011 to 2014 in Japan. TC and TG levels were determined in cord blood samples. A total of 70,535 pairs of neonates (male: 36,001, female: 34,524) and mothers were included. The mean cord blood TC and TG levels were 72.2mg/dL and 24.4mg/dL, respectively. Multiple regression analyses revealed that gestational age and birth weight were significantly associated with cord blood TC (coefficient -2.35, 95% confidence interval [CI] -2.40 - -2.22 and coefficient 0.002, 95% CI 0.002-0.003, respectively) and TG (coefficient 3.09, 95% CI 3.01-3.17 and coefficient - 0.009, 95% CI - 0.009-0.008, respectively) levels. Mean cord blood TG and TC levels decreased over the preterm period; however, these parameters increased during the term. Furthermore, the mean cord blood TC and TG levels decreased over the entire range of birth weight categories. Conclusion: Mean cord blood TG and TC levels decreased over the preterm period; however, these parameters increased during the term. Furthermore, the mean cord blood TC and TG levels decreased over the entire range of birth weight categories in Japanese newborns. Maternal complications such as maternal parity, HDP, PROM, maternal obesity and income level were associated with cord TC and TG levels. What is Known: • No studies have ascertained the reference levels of cord blood lipid levels in Japan. What is New: • Mean cord blood TG and TC levels decreased over the preterm period; however, these parameters increased during the term.
