Abstract Background The outbreak of the novel coronavirus SARSCoV-2 (coronavirus disease 2019; COVID-19) has spread to most of countries in the world. The tight relationship of plasma lipids and COVID-19 pneumonia (NCIP-19) has not been well invested. To observe lipid profiles and their alterations in hospitalized patients with COVID-19 and evaluated the prognostic value of lipids for the length of hospital stay (LOS). Methods 248 NCIP-19 cases aged 18 years or older were enrolled in this study. Serum lipids, including triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were detected at admission. In 68 severe cases, levels of serum lipids were subsequently detected every 5 ~ 10 days. Results At admission, median levels of TG, TC, HDL-C, and LDL-C in all patients, were 1.11 mmol/L, 4.00 mmol/L, 0.89 mmol/L and 2.11 mmol/L, respectively. Compared with common cases (n = 174), higher TG and HDL-C, lower LDL-C were observed in severe cases (n = 74). Levels of TC and LDL-C at admission were negatively correlated with LOS. In severe cases, the average levels of serum lipids were lowest at admission and gradually increased during hospitalization. Compared with the LOS ≤ 29d group, serum levels of TC, HDL-C, and LDL-C were significantly lower in the LOS > 29d group at admission; this lower trend always existed during the following tests for TC and LDL-C, but not for HDL-C and TG. Patients with LDL-C ≥ 1.70 mmol/L at admission showed a lower risk of LOS prolongation (adjusted HR = 0.557, 95% CI: 0.409–0.759, p < 0.001). Conclusions In NCIP-19, serum lipid levels were low at admission. Levels of TC and LDL-C at admission were negatively correlated with LOS. LDL-C < 1.7 mmol/L at admission may act as the independent predictor of LOS prolongation. In severe cases, the gradual increase of TC, LDL-C, and HDL-C during the hospitalization might indicate the gradual recovery of the disease.

The tight relationship of plasma lipids and COVID-19 pneumonia (NCIP-19) has not been well invested. To observe lipid profiles and their alterations in hospitalized patients with COVID-19 and evaluated the prognostic value of lipids for the length of hospital stay (LOS). Methods: 248 NCIP-19 cases aged 18 years or older were enrolled in this study. Serum lipids, including triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were detected at admission. In 68 severe cases, levels of serum lipids were subsequently detected every 5 ~ 10 days. Results: At admission, median levels of TG, TC, HDL-C, and LDL-C in all patients, were 1.11 mmol/L, 4.00 mmol/L, 0.89 mmol/L and 2.11 mmol/L, respectively. Compared with common cases (n=174), higher TG and HDL-C, lower LDL-C were observed in severe cases (n=74). Levels of TC and LDL-C at admission were negatively correlated with LOS. In severe cases, the average levels of serum lipids were lowest at admission and gradually increased during hospitalization. Compared with the LOS≤29d group, serum levels of TC, HDL-C, and LDL-C were significantly lower in the LOS>29d group at admission; this lower trend always existed during the following tests for TC and LDL-C, but not for HDL-C and TG. Patients with LDL-C≥1.70 mmol/L at admission showed a lower risk of LOS prolongation (adjusted HR=0.557, 95% CI: 0.409-0.759, p <0.001). Conclusions: In NCIP-19, serum lipid levels were low at admission. Levels of TC and LDL-C at admission were negatively correlated with LOS. LDL-C <1.7 mmol/L at admission may act as the independent predictor of LOS prolongation. In severe cases, the gradual increase of TC, LDL-C, and HDL-C during the hospitalization might indicate the gradual recovery of the disease.

Abstract To obtain the best estimates of the average intraindividual biological variability (CVb) in the concentrations of total cholesterol (TC), low-density lipoprotein cholesterol (LDLC), high-density lipoprotein cholesterol (HDLC), and triglyceride serum lipids in a person's blood, we evaluated results from 30 studies published from 1970 to 1992. The usually more applicable random-effects model estimated an average CVb of 6.1% for TC, 7.4% for HDLC, 9.5% for LDLC, and 22.6% for triglyceride. Composite estimates of the average CVb from all evaluated published studies by different models of estimation ranged from 6.0% to 6.4% for TC, from 6.2% to 7.5% for HDLC, from 7.0% to 9.6% for LDLC, and from 22.4% to 22.9% for triglyceride. Two important factors influenced the reported biological variation of the study subjects: (a) the magnitude of the variability of the analytical method used and (b) the design characteristics of the study--primarily the number of subjects, the sampling interval, and the number of measurements per subject. For TC, we found a statistically significant positive correlation between the reported mean CVb and both the number of study subjects and the analytical variation. For TC and LDLC we estimate CVb as a function of the study design features. The number of patient specimens required to obtain reliable estimates for serum lipid concentrations are determined from the CVb and the current analytical variation.

<p>The study was designed to evaluate the hepatoprotective activity of aqueous extract of cardamom in acute experimental liver injury induced by gentamicin. Twenty four male albino rats were randomly divided into four groups (six rats in each). Animals of the first group served as control and orally (p.o.) received (1 ml/kg saline). The second experimental group was given gentamicin (80 mg/kg i.p.) for 7 days. Third and fourth groups were given aqueous extract of cardamom (100 and 200 mg/kg p.o.) + gentamicin for 7 days, respectively. The degree of hepatoprotection was measured using serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), bilirubin, albumin, and lipid profile levels. In the acute liver damage induced by gentamicin, cardamom aqueous extracts (100 and 200 mg/kg, p.o.) significantly reduced the elevated serum levels of AST, ALT, bilirubin, cholesterol, triglycerides and low density lipoprotein cholesterol (LDL-chol) in gentamicin induced hepatotoxicity. Also cardamom aqueous extracts (100 &amp; 200 mg/kg, p.o.) significantly increased the lowered serum levels of albumin and high density lipoprotein cholesterol (HDL-chol) in gentamicin induced hepatotoxicity rats. Histopathological examination of the liver tissues supported the hepatoprotection. Our findings concluded that cardamom aqueous extracts possessed hepatoprotective activity against gentamicin induced hepatotoxicity in rats.</p>

BackgroundMounting evidence from both experimental and epidemiological studies suggest that exposure to the endocrine disruptor bisphenol A (BPA) has a role in metabolic disorders. The aim of the present study was to assess whether urinary BPA concentrations were associated with dyslipidaemia in children (≤17 years old) and adults (≥18 years old) by performing a meta-analysis of data from six cycles (2003–2014) in the National Health and Nutrition Examination Survey (NHANES).MethodsWe conducted a meta-analysis of data from 4604 children and 10 989 adult participants who were part of a substudy of urinary BPA measurements from six NHANES cycles from 2003 to 2014. Linear regression models conducted in each cycle were used to perform a meta-analysis to investigate associations between urinary BPA and serum levels of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), triglycerides (TG) and apolipoprotein B (ApoB).ResultsThe meta-analysis did not disclose any significant associations between urinary BPA concentrations and LDL-C, HDL-C, TC, TG and ApoB in children. In adults, the meta-analysis revealed negative regression coefficients for all five lipid variables. However, no associations were significant following Bonferroni correction for multiple tests.ConclusionsIn the present meta-analysis of cross-sectional data from NHANES, no associations were found between urinary BPA and the five different lipid variables when investigated in both children and adults. However, considering the cross-sectional nature of the present study, results should be clarified in carefully designed longitudinal cohort studies with repeated BPA measurements.

Abstract Background The effect of serum lipids on ovarian cancer is controversial. We conduct this study to evaluate the prognostic value of preoperative plasma lipid profile in patients with ovarian cancer. Methods The medical records of 156 epithelial ovarian cancer patients who underwent surgical resection in our department were retrospectively reviewed and analyzed. Serum lipids profiles, including total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), apolipoprotein A-Ⅰ (apoA-Ⅰ), apolipoprotein B (apoB) and clinicopathologic data were analyzed. Cox proportional hazards regression analyses and Kaplan-Meier method were performed to evaluate the overall survival (OS) and progression-free survival (PFS). Results Multivariable Cox regression analysis found that preoperative higher LDL-C level was significantly associated with worse OS (HR 2.088, 95% CI 1.052–4.147, p = 0.035), whereas higher HDL-C level showed significant association with better PFS (HR 0.491, 95% CI 0.247–0.975, p = 0.042). Further Kaplan–Meier survival analysis demonstrated that OS was longer for patients with low levels of LDL-C (< 2.76 mmol/L) compared to those with high levels of LDL-C (≥ 2.76 mmol/L) (P = 0.028), and PFS was better for patients with high levels of HDL-C (≥ 1.19 mmol/L) compared to those with low levels of HDL-C (< 1.19 mmol/L) (P = 0.001). Conclusions Preoperative HDL-C and LDL-C levels are significant predictors of clinical outcome in patients with epithelial ovarian cancer.
