Corn (Zea mays L) Boiled Water Provides Good Evidence for Lowering of Lipid Profile (HDL-C, LDL-C, Triglycerides, and Total Cholesterol) in Dyslipidemia

@#Introduction: Dyslipidemia is a significant factor in cardiovascular and other diseases. Corn can be used to treat dyslipidemia. This study is to determine the effect of boiled corn water on levels of HDL-C, LDL-C, triglycerides (TG), and total cholesterol (TC) in people with dyslipidemia in certain areas in Indonesia. Methods: We used a quasi-experimental pretest-posttest control group design. A sample of 40 people for each group was taken using a purposive sampling technique. The group was given the intervention of corn-boiled water @ 200cc twice daily for seven days. Blood lipid profile using fasting and examined by Fluorometric-enzymatic assay method. All procedures are carried out based on operational standards. Within-group comparisons used the Wilcoxon test, while between-group comparisons used the Mann-Whitney U and Independent T-Test. Results: The LDL-C control group experienced an increase of 65.1 mg/dL, and the entire group’s lipid profile variation showed no difference between the pretest and posttest (p>.05). The intervention group showed an increase in HDL-C (0.1 mg/dL), a decrease in LDL-C (30.2 mg/ dL), TG (27.0 mg/dL), and TC (35.6 mg/dL). Within-group comparison of the intervention group showed HDL-C (p.153), LDL-C (p.001), TG (p.023), and TC (p<.001). A between-group comparison showed HDL-C (p.101), LDL-C (p.034), TG (p.003), and TC (p.006). Conclusion: Whole corn boiled water provides good evidence that it is effective in lowering LDL-C, TG, and TC, as well as improving dyslipidemia in HDL-C patients. This intervention can be used as an alternative treatment for dyslipidemia in terms of nutrition.

Monocyte-to-high-density lipoprotein cholesterol ratio predicts early neurological deterioration and hemorrhagic transformation after intravenous thrombolytic therapy in patients with acute ischemic stroke / 国际脑血管病杂志

Objective:To investigate the predictive value of monocyte-to-high-density lipoprotein cholesterol ratio (MHR) for early neurological deterioration (END) and hemorrhagic transformation (HT) after intravenous thrombolysis in patients with acute ischemic stroke (AIS).Methods:Patients with AIS received IVT in Hefei Second People's Hospital from May 2020 to January 2022 were retrospectively enrolled. Blood collection was completed and MHR was calculated before intravenous thrombolysis. END was defined as an increase of ≥2 from the baseline in the National Institutes of Health Stroke Scale (NIHSS) score or ≥1 from the baseline in motor function score at any time within 7 d after admission. HT was defined as intracranial hemorrhage newly found by CT/MRI within 24 h after intravenous thrombolysis. Multivariate logistic regression analysis was used to determine the independent predictors of END and HT, and the receiver operating characteristic (ROC) curve was used to analyze the predictive value of MHR for END and HT. Results:A total of 186 patients with AIS treated with IVT were included, of which 50 (26.9%) had END and 31 (16.7%) had HT. The median MHR was 0.43. The MHR in the END group was significantly higher than that in the non-END group (0.49 vs. 0.40; P=0.008), and the MHR in the HT group was significantly higher than that in the non-HT group (0.52 vs. 0.40; P=0.013). All patients were divided into 4 groups (MHR1, MHR2, MHR3 and MHR4) according to the MHR quartile from low to high. Multivariate logistic regression analysis showed that after adjusting for confounding factors, taking MHR1 as a reference, MHR3 (odds ratio [ OR] 6.317, 95% confidence interval [ CI] 1.465-27.237; P=0.013) and MHR4 ( OR 8.064, 95% CI 1.910-34.051; P=0.005) were the significant independent predictors of END; Taking MHR1 as a reference, MHR4 ( OR 5.147, 95% CI 1.194-22.182; P=0.028) was the significant independent predictor of HT. The ROC curve analysis showed that the area under the curve of MHR for predicting END was 0.628 (95% CI 0.554-0.698; P=0.008). When the optimal MHR cutoff value was 0.41, its sensitivity and specificity for predicting END was 74.0% and 53.7% respectively. The area under the curve of MHR for predicting HT was 0.642 (95% CI 0.569-0.711; P=0.013). When the best cutoff value was 0.44, the sensitivity and specificity of MHR for predicting HT were 77.4% and 58.1% respectively. Conclusion:Higher MHR is a risk factor for END and HT after intravenous thrombolysis in patients with AIS, but the predictive value of MHR for END and HT is limited.

Evaluation of the relationship between monocyte to high-density lipoprotein cholesterol ratio and thrombus burden in patients with deep vein thrombosis

SUMMARY OBJECTIVE: The purpose of this study was to evaluate monocyte count and high-density lipoprotein cholesterol levels and their ratio (monocyte/high-density lipoprotein ratio) in patients with deep venous thrombosis as well as to determine whether this ratio at the time of diagnosis can be an indicator of thrombus burden in terms of thrombus location in deep venous thrombosis. METHODS: We retrospectively analyzed the patient's diagnosis of deep venous thrombosis confirmed with venous Doppler ultrasound, using a database query for outpatients between 2018 and 2022. Of 378 patients included, blood count results at the time of diagnosis were available for 356. We recruited 300 age- and sex-matched patients with appropriate blood counts, without a diagnosis of deep venous thrombosis, as the control group, by querying the outpatient clinic database. The monocyte/high-density lipoprotein ratio was computed from the ratio of monocyte count to high-density lipoprotein-C. Patients were categorized based on the level of thrombus and the number of vein segments involved as evidenced by Doppler ultrasound findings. RESULTS: The serum level of monocyte/high-density lipoprotein ratio was significantly higher in the patient group compared to the control group (p<0.01). Patients with proximal deep venous thrombosis had a higher mean monocyte/high-density lipoprotein ratio (19.6±5.1 vs. 17.1±5.5; p<0.01) than patients with distal deep venous thrombosis. Monocyte/high-density lipoprotein ratio increased with the number of vein segments involved (p<0.01). CONCLUSION: Monocyte/high-density lipoprotein ratio is significantly elevated in patients with deep venous thrombosis when compared to the control group. Monocyte/high-density lipoprotein ratio levels were correlated with disease burden reflected by thrombus location and the number of vein segments involved in deep venous thrombosis patients.

Associação Positiva entre Autoanticorpos contra LDL Oxidada e HDL-C: Um Novo Mecanismo para Cardioproteção de HDL? / Positive Association between Autoantibodies Against Oxidized LDL and HDL-C: A Novel Mechanism for HDL Cardioprotection?

Resumo Fundamento No microambiente da placa aterosclerótica, os fosfolipídios oxidados expressos na superfície de lipoproteína de baixa densidade oxidada (oxLDL) se ligam a receptores scavenger em macrófagos provocando a formação de células espumosas e a progressão da placa. Autoanticorpos contra oxLDL (oxLDL-Ab) interagem com epítopos oxidativos levando à formação de imunocomplexos que são incapazes de interagir com receptores de macrófagos, assim suprimindo a aterogênese. A liberação de oxLDL-Ab pelas células B envolve a resposta da interleucina 5 e Th2, que por sua vez são potencializadas pela HDL. Assim, levantamos a hipótese de que indivíduos com níveis mais altos de HDL-C podem apresentar níveis elevados de oxLDL-Ab. Objetivo Avaliar a relação entre os níveis de HDL-C e oxLDL-Ab. Métodos Indivíduos assintomáticos (n = 193) foram agrupados de acordo com sua concentração de HDL-C para uma das três categorias seguintes: baixa (< 68 mg/dL), intermediária (de 68 a 80 mg/dL) ou alta (> 80 mg/dL). Os valores p < 0,05 foram considerados estatisticamente significativos. Resultados Nossa análise incluiu 193 indivíduos (média etária: 47 anos; masculino: 26,3%). Em comparação com os indivíduos no menor tercil de HDL-C, os mais elevados foram mais velhos (36 versus 53 anos; p = 0,001) e, menos frequentemente, masculinos (42,6% versus 20,9%; p = 0,001). Os valores médios de oxLDL-Ab aumentaram à medida que o grupo HDL-C aumentou (0,31, 0,33 e 0,43 unidades, respectivamente; p = 0,001 para tendência). A regressão linear simples encontrou uma relação significativa e positiva entre a variável independente, HDL-C, e a variável dependente, oxLDL-Ab (R = 0,293; p = 0,009). Essa relação manteve-se significativa (R = 0,30; p = 0,044), após ajuste por covariáveis. Os níveis de apolipoproteína AI também estiveram relacionados a oxLDL-Ab nos modelos de regressão linear simples e ajustada. Conclusões HDL-C e oxLDL-Ab estão independentemente relacionados.

Abstract Background In the atherosclerotic plaque microenvironment, oxidized phospholipids expressed in the oxidized low-density lipoprotein (oxLDL) surface bind to scavenger receptors of macrophages eliciting foam cell formation and plaque progression. Auto-antibodies against oxLDL (oxLDL-Ab) interact with oxidative epitopes leading to the formation of immune complexes that are unable to interact with macrophage receptors, thus abrogating atherogenesis. Release of oxLDL-Ab by B cells involves interleukin 5 and Th2 response, which in turn are potentiated by HDL. Thereby, we hypothesized that individuals with higher levels of HDL-C may plausibly display elevated titers of oxLDL-Ab. Objective To evaluate the relationship between HDL-C and oxLDL-Ab levels. Methods Asymptomatic individuals (n = 193) were grouped according to their HDL-C concentration to one of three categories: low (< 68 mg/dL), intermediate (68 to 80 mg/dL) or high (> 80 mg/dL). P values < 0.05 were considered statistically significant. Results Our analysis included 193 individuals (mean age: 47 years; male: 26.3%). Compared to individuals in the lowest HDL-C tertile, those in the highest tertile were older (36 versus 53 years; p = 0.001) and less frequently male (42.6% versus 20.9%; p = 0.001). Mean values of oxLDL-Ab increased as the HDL-C group escalated (0.31, 0.33 and 0.43 units, respectively; p = 0.001 for trend). Simple linear regression found a significant, positive relationship between the independent variable, HDL-C, and the dependent variable, oxLDL-Ab (R = 0.293; p = 0.009). This relation remained significant (R = 0.30; p = 0.044), after adjustment by covariates. Apolipoprotein AI levels were also related to oxLDL-Ab in both simple and adjusted linear regression models. Conclusion HDL-C and oxLDL-Ab are independently related.

changes occur commonly among patients affected with malaria. This study aimed to assess lipid changes in blood among patients with malaria in Butembo, a hypoendemic region. Methods: This cross-sectional study, conducted in the Departments of Internal and Parasitology of Matanda Hospital, located in Butembo, from July 1st, 2020, to November 2, 2020; involved 100 patients diagnosed with malaria. Biochemical analyses carried out by three lab technicians were performed among patients who had positive malaria using positive thick film. Plasmodial species, the parasite density, the triglycerides, the total cholesterol, the HDL-cholesterol, the LDL-cholesterol were assessed. Results: Cholesteroleamia and HDLemia demonstrated a low level in 93% and in 61% of participants respectively; whereas 73% of cases showed an increased level of triglycerides in the blood. Lipidemia profile was independently associated with parasite density among patients with malaria. Conclusion: Although the lipid changes in the blood are not specific in the diagnosis of malaria, this study highlighted their status among patients with malaria. Further researches should be conducted to determine their impact on malaria outcomes. Therefore, dyslipidemia could be used in malaria screening.

Association between monocyte-to-high-density lipoprotein cholesterol ratio and nonalcoholic fatty liver disease / 临床肝胆病杂志

ObjectiveTo investigate the association between monocyte-to-high-density lipoprotein cholesterol ratio (MHR) and nonalcoholic fatty liver disease (NAFLD). MethodsA total of 208 patients who were admitted to Department of Gastroenterology, Zhongshan Hospital Affiliated to Dalian University, from January 2018 to October 2020 and were diagnosed with NAFLD by abdominal CT were enrolled as NAFLD group, and 210 healthy individuals were enrolled as control group. All subjects underwent routine blood test, biochemical examination, and abdominal CT examination, and serum MHR was calculated. In addition, according to abdominal CT findings, the patients with NAFLD were divided into mild NAFLD group with 148 patients and moderate-to-severe NAFLD group with 60 patients, and the variables such as white blood cell count (WBC) and MHR were compared between the three groups. The independent samples t-test was used for comparison of normally distributed continuous data between two groups, and a one-way analysis of variance was used for comparison between multiple groups; the Mann-Whitney U test was used for comparison of data with skewed distribution between two groups, and the Kruskal-Wallis H test was used for comparison between multiple groups. The fourfold table chi-square test was used for comparison of categorical data between two groups, and the R×C table chi-square test was used for comparison between three groups. A Spearman correlation analysis was used to investigate the correlation of MHR with metabolic markers and the severity of NAFLD. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of MHR in predicting NAFLD. ResultsCompared with the control group, the NAFLD group had significant increases in body weight (t=-10.573, P＜0.001), body mass index (BMI) (t=-13.112, P＜0.001), smoking history (Z=14.667, P＜0.001), WBC (t=-7.359, P＜0.001), monocytes (Z=-9.932, P＜0001), low-density lipoprotein cholesterol (t=-3.394, P=0.001), triglyceride (TG) (Z=-11.737, P＜0001), cholesterol (t=-2.985, P=0.003), fasting blood glucose (FBG) (Z=-7.827, P＜0.001), alanine aminotransferase (ALT) (Z=-12.583, P＜0.001), and aspartate aminotransferase (AST) (Z=-9.514, P＜0.001) and a significant reduction in serum high-density lipoprotein cholesterol (HDL-C) (t=10.440, P＜0.001); in addition, MHR level had gender differences, and male patients had a significantly higher level than female patients (P＜0.001). Compared with the control group and the mild NAFLD group, the moderate-to-severe NAFLD group had a significant increase in serum MHR level (P＜0.001). The correlation analysis showed that serum MHR level was negatively correlated with HDL-C (r=-0.565, P＜0.001) and were positively correlated with smoking history, body weight, BMI, WBC, monocytes, TG, FBG, ALT, and AST (r=0.449, 0.482, 0.430, 0.478, 0.892, 0.333, 0.157, 0.386, and 0281, all P＜0.01). At the same time, MHR level was positively correlated with the severity of NAFLD (r=0.629, P＜0.001). The ROC curve showed that MHR had an area under the ROC curve of 0.846 (95% confidence interval: 0.810-0.882, P＜0.001), with a sensitivity of 77.9% and a specificity of 74.3%. ConclusionSerum MHR level is associated with NAFLD and can be used as a predictive index for evaluating the progression of NAFLD.

Influence of high-density lipoprotein cholesterol on the prognosis of patients with alcohol-related hepatocellular carcinoma after radical treatment / 临床肝胆病杂志

ObjectiveTo investigate the association of high-density lipoprotein cholesterol (HDL-C) with the prognosis of patients with alcohol-related hepatocellular carcinoma (HCC) after radical treatment. MethodsA retrospective analysis was performed for the clinical data of 43 patients with alcohol-related HCC who were admitted to The Fifth Medical Center of Chinese PLA General Hospital and underwent radical treatment from January 2008 to July 2015, and according to HDL-C level, the patients were divided into normal group with 26 patients and abnormal group with 17 patients. The two groups were compared in terms of basic information, laboratory markers, imaging indices, Barcelona Clinic Liver Cancer tumor stage, and Child-Pugh class of liver function. The t-test test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier method was used to plot survival curves and the log-rank test was used for comparison between groups. Univariate and multivariate Cox proportional hazards models were used to analyze independent risk factors for prognosis. ResultsThere was a significant difference in prealbumin between the two groups (162.38±60.86 mg/L vs 120.06±64.08 mg/L, t=2.184, P=0.035). Number of tumors (hazard ratio ［HR］=2.839, 95%confidence interval ［CI］: 1.120~7.200,P=0.028), tumor size (HR=2.634, 95%CI: 1.062~6.529,P=0037), and HDL-C level (HR=2.400, 95%CI: 1.040~5.537,P=0.040) were independent risk factors for the overall survival of patients with alcohol-related HCC. There were significant differences in 1-, 3-, and 5-year cumulative survival rates between the normal group and the abnormal group (88.5%/72.4%/55.7% vs 70.6%/43.7%/17.5%, χ2=5.881, P=0.015). ConclusionThe reduction in HDL-C level might indicate poor prognosis of patients with alcohol-related HCC.

Correlation between total cholesterol/high-density lipoprotein cholesterol ratio and asymptomatic carotid atherosclerotic plaque stability / 国际脑血管病杂志

Objective:To investigate the correlation between total cholesterol (TC)/high-density lipoprotein cholesterol (HDL-C) ratio and unstable carotid plaque.Methods:From February 2021 to May 2021, adult patients with asymptomatic carotid atherosclerotic plaque admitted to the Department of Neurology, the First People's Hospital of Lianyungang were retrospectively enrolled. The demographic and related clinical data were collected. Carotid artery plaques were detected by ultrasound, and the subjects were divided into a stable plaque group and an unstable plaque group. Multivariate logistic regression analysis was used to assess the independent risk factors for unstable carotid plaques. Receiver operating characteristic (ROC) curve was used to evaluate the predictive efficacy of TC/HDL-C ratio for unstable carotid plaques. Results:A total of 362 patients with asymptomatic carotid atherosclerotic plaque were enrolled, including 226 (62.43%) in the stable plaque group and 136 (37.57%) in the unstable plaque group. Multivariate logistic regression analysis showed that after adjusting for confounding factors, only TC/HDL-C ratio was the independent risk factor for unstable carotid plaque (taking the 1 st quintile array of TC/HDL-C ratio as a reference, the 4 th quintile array: odds ratio 3.13, 95% confidence interval 1.50-6.55, P=0.002; the 5 th quintile array: odds ratio 6.75, 95% confidence interval 3.21-14.22, P<0.001). ROC curve analysis showed that the area under the curve of TC/HDL-C ratio for predicting unstable carotid plaque was 0.691 (95% confidence interval 0.634-0.748; P<0.001), the optimal cut-off value was 4.38, and the sensitivity and specificity were 50.0% and 82.7%, respectively. Conclusion:TC/HDL-C ratio is an independent risk factor for unstable carotid plaques and has a certain predictive value for unstable carotid plaques.

Evaluation of monocyte to HDL cholesterol ratio and other inflammatory markers in patients with psoriasis

Abstract Background Psoriasis is a chronic systemic inflammatory disease frequently associated with serious comorbidities. Objectives To investigate the systemic inflammatory burden in psoriasis and to assess the correlation between traditional and novel inflammatory markers and the severity of the disease. Methods This cross-sectional study was conducted on 60 patients with psoriasis vulgaris and 50 healthy volunteers. Data including demographics, Psoriasis Area and Severity Index scores, and laboratory results were analyzed and compared. Results Compared with the control group, the psoriatic patients had significantly higher high sensitive C-reactive protein, serum amyloid A, erythrocyte sedimentation rate, leukocyte, neutrophil, neutrophil-to-lymphocyte ratio, monocyte to high density lipoprotein (HDL) cholesterol ratio, and aspartate aminotransferase levels, and significantly lower HDL cholesterol levels (p < 0.05). No significant difference was found in procalcitonin, lymphocyte, monocyte, hemoglobin, red blood cell distribution width, platelet, mean platelet volume, platelet distribution width, lymphocyte-to-monocyte ratio, anti-cyclic citrullinated peptide, glucose, alanine aminotransaminase, blood urea nitrogen, creatinine, triglyceride, total cholesterol, and LDL cholesterol levels between the two groups (p > 0.05). The Psoriasis Area and Severity Index score was positively correlated with high-sensitivity C-reactive protein, serum amyloid A, and monocyte to HDL cholesterol ratio, and negatively correlated with lymphocyte-to-monocyte ratio (p < 0.05). Study limitations This was a single-center study with relatively limited numbers of patients and controls. Conclusions The data show that high sensitivity C-reactive protein, serum amyloid A, erythrocyte sedimentation rate, neutrophil-to-lymphocyte ratio, and monocyte to HDL cholesterol ratio can be used as markers of systemic inflammation in patients with psoriasis. Moreover, high sensitivity C-reactive protein, serum amyloid A, monocyte to HDL cholesterol ratio and lymphocyte-to-monocyte ratio are closely related to the Psoriasis Area and Severity Index score, and they may be regarded as objective indicators in determining the disease severity.

Serum elabela level significantly increased in patients with complete heart block

Abstract Objective: To investigate the change in serum Elabela level, a new apelinergic system peptide, in patients with complete atrioventricular (AV) block and healthy controls. Methods: The study included 50 patients with planned cardiac pacemaker (PM) implantation due to complete AV block and 50 healthy controls with similar age and gender. Elabela level was measured in addition to routine anamnesis, physical examination, and laboratory tests. Patients were divided into two groups, with and without AV block, and then compared. Results: In patients with AV block, serum Elabela level was significantly higher and heart rate and cardiac output were significantly lower than in healthy controls. Serum Elabela level was found to be positively correlated with high-sensitive C-reactive protein and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, but negatively correlated with heart rate, high-density lipoprotein cholesterol, and cardiac output. In linear regression analysis, it was found that these parameters were only closely related to heart rate and NT-proBNP. Serum Elabela level was determined in the patients with AV block independently; an Elabela level > 9.5 ng/ml determined the risk of complete AV-block with 90.2% sensitivity and 88.0% specificity. Conclusion: In patients with complete AV block, the serum Elabela level increases significantly before the PM implantation procedure. According to the results of our study, it was concluded that serum Elabela level could be used in the early determination of patients with complete AV block.

RESUMEN Objetivo: Realizar un análisis clínico-epidemiológico de las subfracciones de colesterol unido a lipoproteinas de alta densidad (HDL-C, por sus siglas en inglés) en adultos de la ciudad de Maracaibo, Venezuela. Materiales y métodos: Se realizó un estudio descriptivo y transversal de la base de datos del Estudio de Prevalencia de Síndrome Metabólico de Maracaibo, que incluyó 359 individuos de ambos sexos, mayores de 18 años, a quienes se les determinó la concentración sérica de HDL3 y HDL2, así como el índice HDL2/HDL3; evaluando sus niveles según características sociodemográficas, clínicas y bioquímicas. Resultados: La edad promedio de la población era 39,4 ± 15,2 años, y 51,5% era de sexo femenino. Solo se observaron diferencias en los niveles de HDL-C en aquellos sujetos con HDL-C bajas. Las mujeres con hipertriacilgliceridemia mostraron concentraciones séricas de HDL3 y HDL2 significativamente menores con respecto a aquellas con triacilglicéridos normales (p=0,033); asimismo, se encontró una concentración menor de HDL3 y relación HDL2/HDL3 en aquellas con proteína C reactiva ultrasensible (PCR-us) elevada (p<0,001). En hombres, se evidenció una concentración significativamente menor de HDL2 en aquellos con algún grado de hipertensión arterial (p=0,031), insulinorresistencia (p=0,050) y síndrome metabólico (p=0,003); mientras que aquellos con PCR-us elevada mostraron una menor concentración de HDL3 (p=0,011). Conclusión: Las subfracciones de HDL-C muestran un comportamiento clínico epidemiológico variable en adultos de la población de Maracaibo, con promedios más bajos en los hombres, diferencias en los niveles únicamente en aquellos con HDL-C bajas, y sin predominio de alguna subclase según las características sociodemográficas, clínicas y bioquímicas.

ABSTRACT Objective: To carry out a clinical-epidemiological analysis of high-density lipoprotein cholesterol subfractions (HDL-C) in adults from Maracaibo, Venezuela. Materials and methods: A descriptive and cross-sectional study of the database from the Metbolic Syndrome Prevalence in Maracaibo Study was carried out. HDL3 and HDL2 serum concentration, as well as the HDL2/HDL3 ratio, were determined in 359 individuals of both sexes, over 18 years of age. Values obtained were evaluated according to sociodemographic, clinical and biochemical characteristics. Results: Mean population age was 39.4 ± 15.2 years, and 51.5% were female. Differences in HDL-C subfraction levels were only observed in those subjects with low HDL-C levels. Women with hypertriglyceridemia showed significantly lower serum HDL3 and HDL2 concentrations than those with normal triglycerides (p=0.033), as well as a lower HDL3 level and HDL2 / HDL3 ratio in those with higher levels of ultra-sensitive C-reactive protein (us-CRP) (p<0.001). A significantly lower concentration of HDL2 was observed in men with some degree of hypertension (p=0.031), insulin resistance (p=0.050) and metabolic syndrome (p=0.003); while those with elevated us-CRP showed a lower concentration of HDL3 (p=0.011). Conclusion: HDL-C subfractions show varying clinical-epidemiological behavior in adults from Maracaibo. Lower serum levels are observed in men, differences only in those with low HDL-C; and no predominance of any subclass was observed according to sociodemographic, clinical and biochemical characteristics.

Association between metabolic syndrome and euthyroid nodular goiter: a case-control study / Asociación entre el síndrome metabólico y el bocio nodular eutiroideo: un estudio de casos y controles

Abstract Background: Metabolic syndrome is a cluster of metabolic abnormalities and abdominal obesity; its pathophysiologic basis, insulin resistance, has been shown to act as agent in thyroid cell proliferation. Few studies analyze the relationship between metabolic syndrome and thyroid nodular disease, with a substantial knowledge gap. Objective: Determine the association between metabolic syndrome and nodular thyroid disease in a region with adequate iodine intake. Methods: Case-control study. A total of 182 patients referred to radiology to undergo thyroid ultrasonography due to suspicion of thyroid disease. Cases had at least one thyroid nodule greater than 3 mm (n= 91). Controls did not have evidence of thyroid nodules (n= 91). Results: Bivariate analysis showed a significant association between metabolic syndrome and the presence of thyroid nodule (OR 2.56, 95% CI: 1.41-4.66, p <0.05). Low levels of HDL (OR 2.81, 95% CI: 1.54-5.12, p <0.05) and impaired fasting glucose (OR 2.05, 95%CI 1.10 to 3.78, p <0.05) were significantly associated with the presence of thyroid nodule, independent of the presence of metabolic syndrome. Multivariate analysis maintained the association between metabolic syndrome and thyroid nodule with an OR of 2.96 (95%CI 1.47 to 5.95, p <0.05); similarly, the associations of low levels of HDL (OR 2.77, 95%CI 1.44 to 5.3, p <0.05) and impaired fasting glucose (OR 2.23, 95%CI 1.14 to 4.34, p<0.05) with thyroid nodule remained significant. Conclusion: The thyroid nodular disease is associated with increased risk of metabolic syndrome, specifically decreased HDL and impaired fasting glucose levels were the factors that increased association was found.

Resumen Antecedentes: el síndrome metabólico es un conjunto de anormalidades metabólicas y obesidad abdominal; Se ha demostrado que su base fisiopatológica, la resistencia a la insulina, actúa como agente en la proliferación de las células tiroideas. Pocos estudios analizan la relación entre el síndrome metabólico y la enfermedad nodular tiroidea, con una brecha de conocimiento sustancial. Objetivo: determinar la asociación entre el síndrome metabólico y la enfermedad tiroidea nodular en una región con una ingesta adecuada de yodo. Métodos: estudio de casos y controles. Un total de 182 pacientes remitidos a radiología para someterse a una ecografía tiroidea debido a la sospecha de enfermedad tiroidea. Los casos tenían al menos un nódulo tiroideo mayor de 3 mm (n = 91). Los controles no tenían evidencia de nódulos tiroideos (n = 91). Resultados: El análisis bivariado mostró una asociación significativa entre el síndrome metabólico y la presencia de nódulo tiroideo (OR 2.56, IC 95%: 1.41-4.66, p <0.05). Los niveles bajos de HDL (OR 2.81, IC 95%: 1.54-5.12, p <0.05) y glucosa en ayunas alterada (OR 2.05, IC 95% 1.10 a 3.78, p <0.05) se asociaron significativamente con la presencia de nódulo tiroideo, independiente de la presencia de síndrome metabólico. El análisis multivariado mantuvo la asociación entre el síndrome metabólico y el nódulo tiroideo con un OR de 2.96 (IC 95% 1.47 a 5.95, p <0.05); de manera similar, las asociaciones de niveles bajos de HDL (OR 2.77, IC 95% 1.44 a 5.3, p <0.05) y glucosa en ayunas alterada (OR 2.23, IC 95% 1.14 a 4.34, p <0.05) con nódulo tiroideo permanecieron significativas. Conclusión: la enfermedad nodular tiroidea se asocia con un mayor riesgo de síndrome metabólico, específicamente la disminución de HDL y los niveles de glucosa en ayunas alterados fueron los factores que aumentaron la asociación.

Assessment of the Relationship between Monocyte to High-Density Lipoprotein Ratio and Myocardial Bridge / Avaliação da Relação entre a Razão de Monócitos para Lipoproteínas de Alta Densidade e a Ponte Miocárdica

Abstract Background: Assessing the monocyte to high-density lipoprotein ratio (MHR) is a new tool for predicting inflamation, which plays a major role in atherosclerosis. Myocardial bridge (MB) is thought to be a benign condition with development of atherosclerosis, particularly at the proximal segment of the brigde. Objective: To evaluate the relationhip between MHR and the presence of MB. Methods: We consecutively scanned patients referred for coronary angiography between January 2013- December 2016, and a total of 160 patients who had a MB and normal coronary artery were enrolled in the study. The patients' angiographic, demographic and clinic characteristics of the patients were reviewed from medical records. Monocytes and HDL-cholesterols were measured via complete blood count. MHR was calculated as the ratio of the absolute monocyte count to the HDL-cholesterol value. MHR values were divided into three tertiles as follows: lower (8.25 ± 1.61), moderate (13.11 ± 1.46), and higher (21.21 ± 4.30) tertile. A p-value of < 0.05 was considered significant. Results: MHR was significantly higher in the MB group compared to the control group with normal coronary arteries. We found the frequency of MB (p = 0.002) to increase as the MHR tertiles rose. The Monocyte-HDL ratio with a cut-point of 13.35 had 59% sensitivity and 65.0% specificity (ROC area under curve: 0.687, 95% CI: 0.606-0.769, p < 0.001) in accurately predicting a MB diagnosis. In the multivariate analysis, MHR (p = 0.013) was found to be a significant independent predictor of the presence of MB, after adjusting for other risk factors. Conclusion: The present study revealed a significant correlation between MHR and MB.

Resumo Fundamento: A avaliação da razão de monócitos para lipoproteínas de alta densidade (MHR, sigla em inglês) é uma nova ferramenta para se prever o processo inflamatório, o qual desempenha um papel importante na aterosclerose. A ponte miocárdica (PM) é considerada uma condição benigna com desenvolvimento de arteriosclerose, particularmente no segmento proximal da ponte. Objetivo: Avaliar a relação entre a MHR e a presença de PM. Métodos: Examinamos concecutivamente pacientes encaminhados para angiografia coronariana entre janeiro de 2013 e dezembro de 2016, e um total de 160 pacientes, uma parcela dos quais com PM, e outra com artérias coronárias normais, foram incluídos no estudo. As características angiográficas, demográficas e clínicas dos pacientes foram revisadas a partir de registros médicos. Monócitos e colesteróis HDL foram medidos através de hemograma completo. A MHR foi calculada como a razão entre a contagem absoluta de monócitos e o valor do colesterol HDL. Os valores de MHR foram divididos em três tercis, da seguinte forma: tercil inferior (8,25 ± 1,61); tercil moderado (13,11 ± 1,46); e tercil superior (21,21 ± 4,30). Considerou-se significativo um valor de p < 0,05. Resultados: A MHR foi significativamente maior no grupo com PM, em comparação com grupo controle com artérias coronárias normais. Verificamos que a prevalência de PM (p=0,002) aumentou à medida que se elevavam os tercis de MHR. A razão monócitos-colesterol HDL com ponto de corte de 13,35 apresentou sensibilidade de 59% e especificidade de 65,0% (área ROC sob a curva: 0,687, IC95%: 0,606-0,769, p < 0,001) na predição acurada do diagnóstico de PM. Na análise multivariada, a MHR (p = 0,013) mostrou-se um preditor independente significativo da presença de PM, após ajustes para outros fatores de risco. Conclusão: O presente estudo revelou uma correlação significativa entre MHR e PM.

Effects of herbal-cake-separated moxibustion on the repair of vascular endothelial and SDF-1 in rabbits with atherosclerosis / 中国针灸

OBJECTIVE@#To observe the effects of herbal-cake-separated moxibustion on the repair of damaged vascular endothelium structure and the content of stromal cells derived factor 1 (SDF-1) in rabbits with atherosclerosis.@*METHODS@#A total of 75 rabbits were randomly divided into a normal group, a model group, a direct moxibustion group, an atorvastatin calcium group and a herbal-cake-separated moxibustion group, 15 rabbits in each one. The rabbits in the normal group were fed with normal diet, and the remaining rabbits were fed with high-cholesterol diet for 12 weeks to prepare atherosclerotic model. Two groups of acupoints, one was "Juque" (CV 14), "Tianshu" (ST 25) and "Fenglong" (ST 40), the other one was "Xinshu" (BL 15), "Ganshu" (BL 18) and "Pishu" (BL 20), were applied in the direct moxibustion group and herbal-cake-separated moxibustion group; the two groups of acupoints were selected alternatively every other day. The moxibustion was given for 30 min per treatment, once a day for 4 weeks. The rabbits in the atorvastatin calcium group were treated with atorvastatin calcium tablets (1.96 mg•kg•d) which were crushed into powder and mixed into breakfast. After modeling, the rabbits in the normal group and model group received no treatment, and immobilized at the time when moxibustion was applied in other three groups. The levels of total cholesterol (TC) and triglyceride (TG) were measured by enzymic method; the low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were measured by colorimetric method; the morphological structure of aortic wall was observed under optical microscope; the serum level of SDF-1 was determined by enzyme-linked immunosorbent assay (ELISA).@*RESULTS@#After treatment, compared with the normal group, the levels of TC, TG and LDL-C were significantly increased in the model group (all <0.01), and the level of HDL-C was decreased (<0.01). Compared with the model group, the levels of TC, TG and LDL-C were significantly decreased (all <0.01), and the level of HDL-C was significantly increased in the direct moxibustion group, atorvastatin calcium group and herbal-cake-separated moxibustion group (<0.01, <0.05). Compared with the normal group, the morphological structure of aortic wall was significantly damaged in the model group. Compared with the model group, the vascular endothelial structure was improved in the atorvastatin calcium group and herbal-cake-separated moxibustion group, and the pathological change of aorta endothelial in the direct moxibustion group was relieved. After treatment, compared with the model group, the level of SDF-1 was increased in the direct moxibustion group, atorvastatin calcium group and herbal-cake-separated moxibustion group (<0.05, <0.01); the level of SDF-1 in the herbal-cake- separated moxibustion group was higher than that in the direct moxibustion group (<0.05).@*CONCLUSION@#The herbal- cake-separated moxibustion can promote the expression of SDF-1 in serum and repair the damaged aortic endothelial structure.

Higher High Density Lipoprotein 2 (HDL2) to Total HDL Cholesterol Ratio Is Associated with a Lower Risk for Incident Hypertension

BACKGROUND: Recent studies have suggested that high density lipoprotein (HDL) cholesterol is inversely associated with the development of hypertension. We aimed to determine the association between different HDL cholesterol subclasses and risk of future hypertension. METHODS: A total of 270 Japanese Americans (130 men, 140 women) without hypertension between the ages of 34 to 75 years were enrolled. Blood pressure was measured with a mercury sphygmomanometer, and average blood pressure was calculated. Incident hypertension was determined 5 to 6 and 10 to 11 years after enrollment. HDL2, HDL3, and total HDL cholesterol were measured at baseline. RESULTS: During 10 years of follow-up, the cumulative incidence of hypertension was 28.1% (76/270). In univariate analysis, age, diabetes, waist circumference, systolic and diastolic blood pressure, fasting glucose, insulin resistance index, total and low density lipoprotein cholesterol, and visceral adipose tissue were significant predictors for incident hypertension. Among the HDL cholesterol subclass, HDL2 cholesterol was inversely associated with hypertension incidence, but both total and HDL3 cholesterol were not. In addition, HDL2/HDL cholesterol was inversely associated with future hypertension risk. In multivariate analysis, age (odds ratio [OR], 1.71; 95% confidence interval [CI], 1.26 to 2.31; P=0.001), systolic blood pressure (OR, 1.83; 95% CI, 1.31 to 2.56; P < 0.001), and HDL2/HDL cholesterol (OR, 0.71; 95% CI, 0.52 to 0.98; P=0.035), were associated with future development of hypertension. CONCLUSION: A higher proportion of HDL2 cholesterol among total HDL cholesterol predicted a lower risk for incident hypertension. However, concentrations of total HDL, HDL2, and HDL3 cholesterol were not independent predictors of incident hypertension.
