Investigating Causal Relations Between Circulating Metabolites and Alzheimer’s Diseases: A Mendelian Randomization Study

BackgroundMetabolomics is a promising approach that can be used to understand pathophysiological pathways of Alzheimer disease (AD). However, the relationships between metabolism and AD are poorly understood. The aim of this study is to investigate the causal association between circulating metabolites and risk of AD by combining metabolomics with genomics through two-sample Mendelian randomization (MR) approach.MethodsGenetic associations with 123 circulating metabolic traits were utilized as exposures. A large summary statistics data from International Genomics of Alzheimer’s Project was used in primary analysis, including 21,982 AD cases and 41,944 controls. Validation was further performed using family history of AD data from UK Biobank (27,696 cases of maternal AD, 14,338 cases of paternal AD and 272,244 controls). We utilized the inverse-variance weighted method as primary analysis and four additional MR methods (MR-Egger, weighted median, weighted mode, and MR pleiotropy residual sum and outlier) for sensitivity analyses.ResultsWe found one-fold increased risk of developing AD per standard deviation increase in the levels of circulating ApoB (odd ratio (OR)=3.18; 95% confidence interval (CI): 1.52–6.66, P=0.0022) and glycoprotein acetyls (OR=1.21; 95% CI: 1.05–1.39, P=0.0093), serum total cholesterol (OR=2.73; 95% CI: 1.41-5.30, P=0.0030), and low-density lipoprotein (LDL) cholesterol (OR=2.34; 95% CI: 1.53-3.57, P=0.0001). Whereas glutamine (OR=0.81; 95% CI: 0.71-0.92, P=0.0011) were significantly associated with lower risk of AD. We also detected causal effects of several different composition of LDL fractions on increased AD risk, which has been verified in validation. However, we found no association between circulating high-density lipoprotein cholesterol and AD.ConclusionsOur findings provided robust evidence supporting causal effects of circulating glycoprotein acetyls, ApoB, LDL cholesterol, and serum total cholesterol on higher risk of AD, whereas glutamine showed the protective effect. Further research is required to decipher the biological pathways underpinning associations.

CORRELATION BETWEEN DIETING PATTERNS WITH TOTAL CHOLESTEROL LEVELS IN BLOOD IN THE HKBP CHURCH CONGREGATION ON SEPTEMBER 2018

Serum total cholesterol levels above 200mg/ () have repeatedly been correlated with cardiovascular and other degenerative diseases. Many risk factors can lead to , one of which is the dietary pattern. A dietary pattern is one simple way to start, which can be modified to avoid . This study describes the correlation between dietary pattern with serum total cholesterol levels within HKBP church congregation in September 2018 using a cross-sectional study, and the sample was obtained from accidental sampling. Therefore, there is no requirement for both inclusion and exclusion criteria. In total, 38 respondents contributed to this research. Data retrieval was done using questionnaires for the dietary pattern and rapid test for the serum total cholesterol levels. The data was used to analyze by the Pearson Chi-Square test. Based on the study result, there was a significant relationship between carbohydrate consumption frequency with the respondents' serum total cholesterol levels (p = 0,031). In contrast, the significant relationship between protein consumption frequency (p = 0,631), fat consumption frequency (p = 0150), fiber consumption frequency (p = 0,631) and fast-food consumption frequency (p = 0,150) with serum total cholesterol levels of the respondents were not found.

A COMPARATIVE STUDY OF SERUM TOTAL CHOLESTEROL IN PRE AND POST-CHOLECYSTECTOMY PATIENTS UNDERGOING LAPAROSCOPIC CHOLECYSTECTOMY

Background:Laparoscopic cholecystectomy has many advantages over laparotomy like smaller incisions, reduced surgical trauma, less post-operative pain, faster recovery time, shorter hospital stay, and faster return to normal activities or routine work. So, it is considered as the gold standard for surgical treatment of benign gallbladder disease like cholelithiasis.The aim of this study was to elucidate the association of serum total cholesterol with cholelithiasis patients and effect of cholecystectomy on the same by laparoscopic procedure. Methodology: This study was conducted prospectively on 109 patients in a tertiary care hospital in eastern Uttar Pradesh, India. From January 2019 to December 2019, patients admitted for cholecystectomy in General surgery ward of this hospital were included in this study. Fasting blood samples of the patients were collected firstbefore surgery and then 12-24 hours after surgery and were analyzed in the biochemistry laboratory of the institute after proper control and calibration, meeting the quality standard of the laboratory. Values of serum total cholesterol thus obtained were compared with each other. Results: In our study, 84.4% patients were females with mean age of 43.1 years and 15.6% patients were males with mean age of 40.8 years. A reduction in mean value of serum total cholesterol was noted pre-operatively from 221.1 mg/dL to 203.5 mg/dL post-operatively. Conclusion: From our study, we concluded that laparoscopic cholecystectomy is beneficial in lowering down the serum total cholesterol and hence reduces the risk factors for associated diseases.

Hypercholesterolemia Is an Associated Factor for Risk of Differentiated Thyroid Cancer in Chinese Population

BackgroundHyperlipidemia has been hypothesized as a risk factor for thyroid cancer. However, the association between hypercholesterolemia and thyroid cancer is unclear, especially in Chinese population without available published data. We conducted this study to investigate the relationship between hypercholesterolemia and differentiated thyroid cancer (DTC) in Chinese population.MethodsThree thousand seven hundred forty-eight patients were enrolled in the study, including 2,021 DTC patients and 1,727 benign subjects with benign thyroid nodules. Demographic characteristics, medical history, and clinical hematological examination were collected. Stratified analyses of association between hypercholesterolemia and risk of DTC were done. Multivariable logistic regression models were used to estimate the association between hypercholesterolemia and the risk of thyroid nodules being malignant. This study protocol was approved by the ethics committee of Shandong Provincial Qianfoshan Hospital and assigned in ClinicalTrials.gov protocol registration and results system (NCT03006289, https://clinicaltrials.gov/ct2/show/NCT03006289).ResultsThe level of serum total cholesterol in patients with DTC is higher than that in benign subjects (P < 0.001). After adjusting hypercholesterolemia, age (P < 0.001), triglyceride (P = 0.003), and thyroid stimulating hormone (TSH) (P < 0.001) are found to be confounding factors. The risk of DTC in patients younger than 45 years old is 2.08 times than that of patients older than 45 years old (odds ratio = 0.48, 95% CI (0.38, 0.61), P < 0.001). A high TSH level is highly associated with the increased risk of DTC (P < 0.001). The multivariable logistic regression analysis revealed that the absence of hypercholesterolemia could reduce the risk of thyroid nodules being malignant (odds ratio = −0.75, 95% CI (−1.39, −0.12), P = 0.02). Comparing to the higher level of serum total cholesterol (>5.7 mmol/L), the closer the serum total cholesterol level is to normal (3.17–5.7 mmol/L), the less the risk of thyroid nodules being malignant is, and this difference is statistically significant (odds ratio = −0.67, 95% CI (−1.31, −0.03), P = 0.040). However, this difference is not found in the group of patients with lower level of total cholesterol (<3.17 mmol/L, odds ratio = 0.43, 95% CI (−1.22, 2.09), P = 0.068), suggesting that hypocholesterolemia is not a protective factor in the risk of thyroid nodules being malignant.ConclusionsHypercholesterolemia is an associated factor for risk of DTC in Chinese population.

Study of Serum Total Cholesterol in Cirrhosis of Liver And Its Relation With Severity of The Disease

Background: Lipid metabolism is impaired in different directions in liver cirrhosis. Dyslipidaemia seen in cirrhosis of the liver differs from that found in most of the additional reasons of secondary dyslipidaemias because lipoproteins in circulation are not only present in unusual amount but they also often have unusual composition, electrophoretic movement and forms (Nangliya et al., 2015). Materials & Method: This cross-sectional study was carried out in the Department of Biochemistry, Sylhet MAG Osmani Medical College, Sylhet during the period from 1st January 2016 to 31st December 2016.Fiftypatients with cirrhosis of liver fulfilling the inclusion criteria were enrolled as group-A and 50 age-sex matched healthy adults were selected as the control group (group-B). Result: Fasting serum total cholesterol was estimated. Severity of liver Cirrhosis was categorized according to Child-Pugh scoring system and increasing severity was categorized as Child Pugh class A, B and C.Serum total cholesterol is decreased in patients with liver cirrhosis. The level of severity of liver damage significantly affects the serum total cholesterol level in cirrhosis; and may be considered as markers of severity of liver damage in cirrhosis. Conclusion: It may be concluded that hypocholesterelemia exists in patients with liver cirrhosis and screening for severity of cirrhosis by serum total cholesterol is important for intervention with appropriate therapy to reduce the severity of the disease. Key words: Liver cirrhosis,Serum total cholesterol , Child-Pugh score.

Studies on the therapeutic effects of three TCM methods on steroid-induced osteonecrosis of femoral head

Purpose: To determine the therapeutic effects of kidney yang-tonifying, blood-activating and phlegmeliminating methods on steroid-induced osteonecrosis of femoral head (SONFH), and their mechanisms of action.Methods: A rabbit model of SONFH was established. Six rabbit groups were used: control, SONFH (given normal saline); tongluo shenggu group, kidney-tonifying group, blood-activating group, and phlegm--eliminating group, which received tongluo shenggu capsule (0.28 g/kg/day), yougui yin (YGY, 2.52 g/kg/day), taohong siwu decoction (TSD, 2.38 g/kg/day) and linggui zhugan decoction (LZD,1.54 g/kg/day), respectively, for 8 weeks. The following serum indices were assayed on the 2nd, 4th and 8th weeks: total cholesterol, triglycerides, thromboxane B2 (TXB2), 6-keto-PGF1α, osteoprotegerin (OPG), and receptor activator of nuclear factor kappa-Β ligand (RANKL). At the end of the 8th week, mRNA levels of OPG, BMP-2 and VEGF were assayed using real-time fluorescent quantitative polymerase chain reaction (RTF-qPCR).Results: Serum OPG in the kidney-tonifying group was increased, while its RANKL was decreased on the 2nd week, but these parameters, along with mRNA of OPG and BMP-2, reached normal levels at the 8th week (p <0.05). The TXB2 of blood-activating group was decreased, while its 6-keto-PGF1 level was increased at the 2nd week, but both of them attained normal levels at the 8th week, along with VEGF mRNA. Serum total cholesterol, triglycerides and TXB2 in the phlegm-eliminating group were decreased, while its 6-keto-PGF1α was increased at the 2nd week, but the levels of serum total cholesterol and triglycerides were normalized at the 8th week (p <0.05). Histological examination showed increases in bone trabeculae and bone marrow cells, while the proliferation of fat cells was decreased in kidney-tonifying, blood-activating and phlegm-eliminating groups.Conclusion: These findings suggest that the therapeutic effects of the three different TCM methods on SONFH involve different mechanisms.
