RESUMO

Recently, the monocyte count to high-density lipoprotein cholesterol ratio (MHR) was found to be associated with the SYNTAX score in patients with both stable coronary artery disease (CAD) and acute coronary syndrome (ACS). The MHR was significantly higher in male patients. However, the sex-specific association of MHR with SYNTAX score in stable CAD was not well explored. Thus, the present study aimed to investigate the association of MHR and presence and severity of CAD evaluated by coronary angiography and the SYNTAX score in males and females.In total, 873 patients who received selective coronary angiography between March 2017 and July 2018 were included in the present study. Patients were divided into 3 groups according to MHR tertiles. The MHR was calculated by dividing the monocyte count by the high-density lipoprotein cholesterol level. CAD was defined as at least 50% diameter stenosis of a major coronary artery, including the right coronary, left main coronary, left anterior descending, and left circumflex arteries. The SYNTAX score was calculated by 2 experienced interventional cardiologists. SYNTAX score ≥23 was defined as a high SYNTAX score.Males showed a significantly higher MHR (12.2 [8.9-15.5] vs 9.3 [6.2-12.1], P < .001), accompanied by a higher prevalence of CAD (68.1% vs 53.4%, P < .001). Male sex remained an independent predictor of elevated MHR after correction for confounding factors (adjusted odds ratio [OR] 3.102, P = .001). The association between MHR and SYNTAX score was confirmed only in male stable patients with CAD (r = 0.113, P = .036). Multivariate logistic regression analysis showed that MHR was an independent predictor of SYNTAX score ≥23 only in male patients with CAD. The receiver-operating characteristic curve showed a predictive value of MHR for high SYNTAX score only in males.A higher MHR in males and a positive correlation of MHR with SYNTAX score were observed only in male stable patients with CAD. Such an easily obtained index may help interventional cardiologists detect high-risk patients before coronary catheterization, but its application may be restricted to males.

RESUMO

Hyperuricemia has received increasing attention as a major public health problem. This study aims to investigate the risk factors for hyperuricemia and to explore the relationship between changes in biochemical variables and incident hyperuricemia.A cross-sectional and subsequently prospective study was performed among adults who took their health checkups at Zhejiang University Hospital. The participants who were free of hyperuricemia at baseline received annual follow-up examinations during a 6-year period. Cox proportional hazards regression analyses were conducted to calculate the risks for incident hyperuricemia.Of the 9238 participants enrolled, 1704 (18.4%) were diagnosed as hyperuricemia. During 21,757 person-years of follow-up, 1492 incident hyperuricemia cases were identified. The incidence of hyperuricemia was 68.58 cases per 1000 person-year of follow-up in the overall participants. The prevalence and the incidence of hyperuricemia increased greatly in female older than 50 years. High levels of BMI, SBP, FPG, TG, LDL-C, ALT, BUN, and creatinine increased the risk of hyperuricemia. Suffering fatty liver also increased the risk of hyperuricemia. Subjects with increasing DBP, TG, BUN, creatinine, or decreasing HDL-C were more likely to incident hyperuricemia.This study revealed that the change of diastolic blood pressure (DBP), serum triglycerides (TG), blood urea nitrogen (BUN), creatinine, and high-density lipoprotein cholesterol (HDL-C) level were independently associated with incident hyperuricemia.

RESUMO

Dyslipidemia has been described in sickle cell anemia (SCA) but its association with increased disease severity is unknown. Here, we examined 55 children and adolescents with SCA as well as 41 healthy controls to test the association between the lipid profiles in peripheral blood and markers of hemolysis, inflammation, endothelial function, and SCA-related clinical outcomes. SCA patients exhibited lower levels of total cholesterol (P<0.001), low-density lipoprotein cholesterol (LDL-c) (P<0.001), and high-density lipoprotein cholesterol (HDL-c) (P<0.001), while displaying higher triglyceride (TG) levels and TG/HDL-c ratio values (P<0.001). TG/HDL-c values were positively correlated with lactate dehydrogenase (P=0.047), leukocyte count (P=0.006), and blood flow velocity in the right (P=0.02) and left (P=0.05) cerebral artery, while being negatively correlated with hemoglobin levels (P<0.04). Acute chest syndrome (ACS) and vaso-occlusive events (VOE) were more frequent in SCA patients exhibiting higher TG/HDL-c values (odds ratio: 3.77, P=0.027). Multivariate logistic regression analysis confirmed independent associations between elevated TG/HDL-c values and SCA. Thus, children and adolescents with SCA exhibited a lipid profile associated with hemolysis and inflammatory parameters, with increased risk of ACS and VOE. TG/HDL-c is a potential biomarker of severity of disease.

RESUMO

Recently, studies have shown significant association between the rs2000999 polymorphism in the haptoglobin-encoding gene (HP) and low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) levels, which are important risk factors for cardiovascular diseases. However, the association of rs2000999 with serum lipids in Latin American diabetic populations is still uncharacterized. Here, we analyzed the association of rs2000999 with TC, high-density lipoprotein cholesterol (HDL-C), and LDL-C levels in 546 Mexican adults with type 2 diabetes (T2D) and in 654 controls without T2D. In this observational case-control study we included adults from 4 centers of the Mexican Social Security Institute in Mexico City recruited from 2012 to 2015. TC, HDL-C, LDL-C, triglycerides (TG), and glucose levels were measured by an enzymatic colorimetric method. The variant rs2000999 was genotyped using TaqMan real time polymerase chain reaction. The percentage of Native-American ancestry showed a negative association with the rs2000999 A allele. In contrast, the rs2000999 A allele had a strong positive association with European ancestry, and to a lesser extent, with African ancestry. Linear regression was used to estimate the association between the variant rs2000999 and lipid concentrations, using different genetic models. Under codominant and recessive models, rs2000999 was significantly associated with TC and LDL-C levels in the T2D group and in controls without T2D. In addition, the group with T2D showed a significant association between the variant and HDL-C levels. In summary, the rs2000999 A allele in Mexican population is positively associated with the percentage of European and negatively associated with Native American ancestry. Carriers of the A allele have increased levels of TC and LDL-C, independently of T2D diagnosis, and also increased concentrations of HDL-C in the T2D sample.

RESUMO

OBJECTIVE: To analyze the prevalence of altered total cholesterol and fractions levels in the Brazilian population, according to biochemical data from the National Health Survey. METHODS: A descriptive study, using data from the National Health Survey, collected between 2014 and 2015. Total cholesterol and fractions were analyzed and population prevalences of altered values according to socio-demographic variables were calculated. The cutoff points considered were: total cholesterol ≥ 200mg/dl; low-density lipoprotein LDL ≥ 130mg/dL and high-density lipoprotein HDL < 40mg/dL. RESULTS: The prevalence of total cholesterol ≥200mg/dL in the population was 32.7%, and higher in women (35.1%). The prevalence of altered HDL was 31.8%, 22.0% in females and 42.8% in males. LDL ≥ 130mg/dL was found in 18.6% and was higher in women (19.9%). The population aged 45 years old and older and those with low levels of education presented a higher prevalence of altered cholesterol. CONCLUSION: Altered values of total cholesterol and fractions were frequent in the Brazilian population, especially among women, the elderly and people with low levels of education. These results may guide control and preventative actions such as healthy eating, physical activity and treatment, all of which aim to prevent coronary diseases.

RESUMO

The aim of this study was to analyze the correlation between free triiodothyronine (FT3), free thyroxine (FT4), thyroid-stimulating hormone (TSH), and serum high-density lipoprotein cholesterol (HDL-C), and to explore the significance of FT3 in HDL-C metabolism in people with normal thyroid function.A total of 461 Chinese, aged ≥28 years, from a college community in Nanning, Guangxi, were enrolled for a cross-sectional epidemiological investigation of metabolic syndrome from October 2016 to November 2016. Height, weight, blood pressure, total cholesterol, HDL-C, triglyceride (TG), fasting glucose (FPG), FT3, FT4, and TSH were measured for each individual. Multiple linear regression analysis was used to evaluate the correlation between FT3, FT4, TSH, and HDL-C.After controlling for sex, age, body mass index (BMI), smoking, drinking, and other confounding factors, FT3 was negatively correlated with HDL-C levels, on average, when FT3 increased by 1 pmol/L, HDL-C decreased by 0.143 mmol /L with a statistically significant difference (P < .001). FT4 was positively correlated with HDL-C, and HDL-C increased by 0.016 mmol/L for every 1-pmol/L increase in FT4. TSH was negatively correlated with HDL-C, and HDL-C decreases by 0.010 mmol/L for every 1-µIU/mL increase in TSH, but the differences were not statistically significant (P > .05).FT3 may be an important factor affecting HDL-C levels. The detection and regulation of thyroid hormone (especially FT3) in patients with low HDL-C, as well as the detection of HDL-C in patients with thyroid dysfunction, is important to prevent the occurrence of cardiovascular diseases.

RESUMO

Introduction: The relationship of the metabolic syndrome (MS) and its components with the reduced glomerular filtration rate and proteinuria is not yet widely elucidated. The aim of the study was to associate the estimated glomerular filtration rate (eGFR) and proteinuria to MS and its individual components in adults with cardiometabolic risk factors, who attended a public health center in the municipality of San Diego, Carabobo State, Venezuela. Methods: Descriptive and cross-sectional study (n=176 individuals). Weight, height, waist circumference, body fat percentage and blood pressure were measured; serum glucose, creatinine, urea, ureic nitrogen, total cholesterol, low (LDLc) and high (HDLc) density lipoprotein cholesterol, triglycerides and glycosylated hemoglobin A1C in whole blood were determined; the presence of proteinuria was determined in partial urine. The eGFR was estimated by equations and the body mass index (BMI) was calculated. Results: The frequency of MS was significantly higher among patients with CKD (eGFR < 60 mL/min/m2), mildly reduced eGFR (60-89 mL/min/m2), hyperfiltration or proteinuria. The risks of mildly reduced eGFR and protenuria were significantly associated with elevated fasting blood glucose, low HDLc and MS, with and without adjustment for sex, age and BMI. When adjusted for the diabetic condition, only the risk of proteinuria remained associated with MS and elevated blood pressure. The risk of hyperfiltration was not associated with MS. Conclusion: The reduction in estimated glomerular function and proteinuria were associated with MS and its individual components. Other studies that confirm the results are required.

RESUMO

Background: Excess weight (EW) and alterations in lipid metabolism constitute risk factors for cardiovascular disease in adults and children. Prevalence of dyslipidemia in schoolchildren from Jujuy with EW is analyzed in this study. Methods: Cross-sectional descriptive study of 891 schoolchildren 10-14 years old (367 girls; 524 boys) from the province of Jujuy (Northwestern Argentina). Prevalence of dyslipidemia for Overweight (OW) and Obesity (OB) were calculated, according to the International Obesity Task Force cut-off points. Prevalence of lipid alterations were analyzed and 7 dyslipidemic profiles were established. Comparisons and associations between variables were analyzed by Chi-square test. Crude and adjusted odds ratio were estimated from a logistic regressions. Results: Regardless of sex and nutritional status, 13.7%, 21.8%, and 16.5% of schoolchildren showed high values of total cholesterol, triglycerides, and LDL cholesterol, respectively, and 20.3% had low HDL cholesterol. Significantly higher values of HDL cholesterol were found in OW, and of triglycerides in OB. A significant association was recorded between OB and high triglycerides. Schoolchildren with OB have a 54% more chances of showing at least one lipid alteration. Conclusion: EW, and especially OB, constitutes an important risk factor in the development of dyslipidemia in schoolchildren from Jujuy.

RESUMO

Introduction: Some meta-analyses suggested a positive effect of metformin therapy on lipid parameters, but the potential beneficial effect of metformin on cardiovascular risk in type 2 diabetes is not entirely clear. Aim: We investigated the effect of metformin therapy on lipid parameters and cardiovascular risk in patients with type 2 diabetes. Method: In a cross-sectional, monocentric study, 102 patients with type 2 diabetes without lipid-lowering medication were analysed for lipid profile and cardiovascular risk (United Kingdom Prospective Diabetes Study Risk Calculator) depending on metformin therapy. The patients were divided into two subgroups regarding with (n = 52) or without metformin therapy (n = 50). Results: Patients with metformin therapy had significantly lower total cholesterol and LDL cholesterol levels than patients without metformin (p<0.01 and p<0.05). This effect was independent from glucose control. No intrinsic effect of metformin could be found on systolic blood pressure, HDL cholesterol, triglycerides, and long-term cardiovascular risk using a multivariable risk assessment score. Conclusion: Metformin therapy has beneficial effects on cholesterol levels without improving cardiovascular risk in patients with type 2 diabetes. Orv Hetil. 2019; 160(34): 1346-1352.

RESUMO

Introduction: Sickle cell anaemia (SCA) is an inherited abnormality of haemoglobin associated with reduced life expectancy. Patients' complications include dyslipideamia. This study was aimed at determining the artherogenic index of plasma (AIP) in sickle cell anaemia patients and compares the value to HbAA controls value. A high AIP is strongly predictive of elevated cardiovascular risk. Methods: A comparative study was conducted among SCA patients attending the haematology clinic, Lagos State University Teaching Hospital (LASUTH) and HbAA Phenotype controls. A total of 304 participants were recruited consisting of equal numbers of SCA and HbAA controls. Single lipid profiles were done; logarithms of triglycerides/high density lipoprotein were calculated to obtain AIP and lipid profile ratios established for all participants. Results: There were lower mean values of Total Cholesterol (TC), High Density Lipoprotein(HDL) and Low Density Lipoprotein (LDL) amongst SCD participants than controls and higher mean values of triglycerides (TG) and Very Low Density Lipoprotein (VLDL) in SCD p < 0.05. The AIP in SCD ranges from -0.62 to 1.32 while that of controls ranges from -0.56 to 0.61.The mean AIP were 0.14 ± 0.29 and -0.009 ± 0.26 in SCD and controls respectively. P value = 0.002. Conclusion: AIP value is higher in sickle cell anaemia than controls, the former have lower mean values of TC, HDL and LDL and higher mean values of TG and VLDL.

RESUMO

Osteoporosis (OP) is a disease characterized by decreased bone mineral density (BMD) and an increased risk of osteoporotic fractures. Nutritional factors (including glucose and fats lipids), have been implicated in OP.We hypothesized that the levels of blood glucose and lipids could be biomarkers for predicting the risk of OP. To test this hypothesis, we evaluated the potential relationship between BMD and levels of blood glucose and lipids via a community-based study in China.This was a community-based cross-section analysis, and a total of 8584 cases were investigated. The BMD of the left calcaneus was measured using an ultrasonic bone densitometer. The levels of blood glucose (fasting blood glucose [FBG], 2-h blood glucose [2hBG], and glycosylated hemoglobin [HbAlc]), and lipids (triglyceride [TG], total cholesterol [TC], low-density lipoprotein cholesterol [LDL-C], and high-density lipoprotein cholesterol [HDL-C]) were measured and analyzed.In our study population, the levels of FBG, 2hBG, HbAlc, TC, LDL-C and HDL-C were higher in the OP group than in the low bone density and the normal bone density groups, while the levels of HbAlc, TC, and LDL-C in the low bone density group were higher than those in the normal bone density group. In males, the level of blood LDL-C in the low bone density group was higher than that in the normal bone density group. In postmenopausal subjects, the levels of FBG, 2hBG and HbA1C were higher than those in the normal bone density groups, and the level of HbA1C in the low bone density group was higher than that in the normal bone density group. Pearson linear trend analysis demonstrated that BMD was positively associated with TC and LDL-C in males and negatively associated with FBG, 2hBG and HbA1C in postmenopausal females. Moreover, logistic analysis showed that BMD was correlated with TC in premenopausal females and HbA1C in postmenopausal females.OP is generally associated with abnormal levels of blood glucose and/or lipids; nevertheless, the relationship between OP and abnormal levels of blood glucose and/or lipids is complicate and different subpopulations may have different susceptibilities. Therefore, further detailed studies are warranted.

RESUMO

INTRODUCTION: Previous report showed that more intensive lipid-lowering therapy was associated with less mortality when baseline LDL-C levels were > 100 mg/dL. Non-HDL-C is a better predictor of cardiovascular risk than simpler LDL-C. AIM: The objective of this meta-analysis was to define the impact of lipid-lowering therapy on the reduction of total and cardiovascular mortality by different baseline levels of non-HDL-C. METHODS: We performed a meta-analysis including randomized, controlled clinical trials of lipid-lowering therapy, reporting mortality with a minimum of 6 months of follow-up, searching in PubMed/Medline, EMBASE and Cochrane Clinical Trials databases. The random-effects model and meta-regression were performed. RESULTS: Twenty nine trials of lipid-lowering drugs, including 233,027 patients, were considered eligible for the analyses. According to the baseline non-HDL-C level, the results on cardiovascular mortality were: (1) ≥ 190 mg/dL: OR 0.63 (95% CI 0.53-0.76); (2) 160-189 mg/dL: OR 0.82 (95% CI 0.75-0.89); (3) 130-159 mg/dL: OR 0.71 (95% CI 0.52-0.98); (4) < 130 mg/dL: OR 0.95 (95% CI 0.87-1.05). When evaluating mortality from any cause, the results were the following: (1) ≥ 190 mg/dL: OR 0.70 (95% CI 0.61-0.82); (2) 160-189 mg/dL: OR 0.91 (95% CI 0.83-0.98); (3) 130-159 mg/dL; OR 0.88 (95% CI 0.77-1.00); (4) < 130 mg/dL: OR 0.98 (95% CI 0.91-1.06). The meta-regression analysis showed a significant association between baseline non-HDL-C and mortality. CONCLUSIONS: In these meta-analyses, lipid-lowering therapy was associated with reduction in the risk of all-cause and cardiovascular mortality when baseline non-HDL-C levels were above than 130 mg/dL.

RESUMO

The aim of this study was to assess the effects of different dietary approaches on low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglyceride (TG) levels in patients with type 2 diabetes (T2D) by applying network meta-analysis (NMA). Systematic electronic and hand searches were conducted until January 2018. Randomized controlled trials (RCTs) with an intervention period of ≥ 12 weeks, focussing on adults with T2D, and comparing dietary approaches regarding LDL, HDL or TGs, were included. For each outcome measure, random effects NMA was performed in order to determine the effect of each dietary approach compared to every other dietary intervention. Mean differences (MDs) and 95% confidence intervals (95% CIs) were calculated, and for the ranking, the surface under the cumulative ranking curves (SUCRA) was determined. Additionally, the credibility of evidence was evaluated. 52 RCTs (44 for LDL, 48 for HDL and 52 for TGs) comparing nine dietary approaches (low fat, vegetarian, Mediterranean, high protein, moderate carbohydrate, low carbohydrate, control, low glycaemic index/glycaemic load and Palaeolithic diet) enrolling 5360 T2D patients were included. The vegetarian diet most effectively reduced LDL levels [MD (95% CI): - 0.33 (- 0.55, - 0.12) mmol/L; compared to the control diet]. The Mediterranean diet beneficially raised HDL [MD (95% CI): 0.09 (0.04, 0.15) mmol/L] and decreased TG levels [MD (95% CI): - 0.41 (- 0.72, - 0.10) mmol/L] compared to the control diet. The Mediterranean diet was the most effective dietary approach to manage diabetic dyslipidaemia altogether (SUCRA: 79%). The overall findings are mainly limited by low credibility of evidence.

RESUMO

Effects of Spirulina platensis 55% ethanol extract (SPL55) on lipid metabolism in high-fat diet-induced hyperlipidaemic rats were investigated. Ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry indicated that SPL55 was enriched with polyunsaturated fatty acids. Meanwhile, serum and liver lipid levels, including total triglyceride, total cholesterol, and low-density-lipoprotein cholesterol, were significantly decreased in hyperlipidaemic rats of SPL55. Analysis of tissue sections showed that SPL55 treatment could markedly inhibit hepatic lipid accumulation and steatosis. Moreover, SPL55 regulated the mRNA and protein expression levels of SREBP-1c, HMG-CoA, PEPCK, ACC, and AMPK genes involved in lipid metabolism. Furthermore, SPL55 led to decrease the abundances of Turicibacter, Clostridium_XlVa, and Romboutsia, which were positive correlation with lipid metabolism indicators, and has also enriched Alloprevotella, Prevotella, Porphyromonadaceae, and Barnesiella. These results provided evidence that SPL55 might be developed as a functional food to ameliorate lipid metabolic disorders and hyperlipidaemia.

RESUMO

Objective: To analyze the longitudinal change of serum total cholesterol concentration in 733 rural residents in Shanxi province. Methods: Based on the residents of five rural areas in Shanxi province who participated in China nutrition and health survey in 2002, a follow-up survey was conducted in 2015. Fasting venous blood of the participants was collected and serum TC concentration was tested by cholesterol oxidase method. Results: Of 733 participants, 332 were male and 401 were female. In 2002 baseline survey, the age of the participants was (42.6±9.5) years old, 76.2% of male and 83.8% of female had junior middle school education or below. Proportion of smoking were 65.7% and 1.2%, drinking were 26.8% and 4.0%, obesity were 6.3% and 12.0%, and central obesity were 27.1% and 31.9%, respectively in male and female. The follow-up age of participants in 2015 was (55.8±9.5) years old, proportion of smoking changed to 48.2% and 1.5%, drinking were 49.7% and 3.0%, obesity increased to 11.8% and 18.2% and central obesity increased to 41.6% and 53.6%, respectively in male and female. The overall serum TC level increased from (3.82±0.89) mmol/L to (4.72±0.97) mmol/L with an average increase of 27.2%, which increased from (3.84±0.94) mmol/L to (4.54±0.93) mmol/L in male with an average increase of 22.7%, and increased from (3.81±0.84) mmol/L to (4.86±0.98) mmol/L in female with an average increase of 30.9%. The serum TC levels in 18-, 30-, 40-, and 50-59 years old group increased from (3.42±0.83), (3.72±0.77), (3.90±0.83) and (4.00±1.03) mmol/L to (4.38±1.01), (4.79±0.92), (4.73±0.99) and (4.76±0.96) mmol/L, with average increase range of 31.4%, 32.1%, 25.2% and 22.6%, respectively. The mean serum TC levels between two years all had statistically significant difference among groups of gender, age, education, marital status, family history of cardiovascular disease, smoking, drinking, BMI and waist circumference after paired t-test and ANOVA analysis (P<0.01). Conclusion: The longitudinal serum TC level of rural residents in Shanxi province increased rapidly.

RESUMO

BACKGROUND: Previous studies identified conflicting results about the effects of wine intake on glucose parameters and the risk of cardiovascular diseases in type 2 diabetes mellitus (T2DM). The present study further investigated the association between wine digestion and these outcomes in T2DM patients. MATERIAL AND METHODS: A search of PubMed, Embase, and Scopus databases (up to November 2018) was performed for randomized interventional trials which evaluated the effect of wine on blood pressure (BP), glucose parameters and lipid profiles in T2DM people. We used a variety of tests: fixed and random effects models, Q Cochrane test and I index, Egger and Begg tests, forest plots, and sensitivity analysis in our study. RESULTS: A total of 9 randomized interventional studies were included in this meta-analysis. Overall, significant association between wine intake with diastolic BP (weighted mean difference [WMD] = 0.10; 95% confidence interval [95% CI]: -0.01 to 0.20, P = .03 I = 13%) and total cholesterol (TC) (WMD = 0.16, 95% CI: 0.02-0.31, P = .03, I = 6%), whereas no noticeable differences in glucose parameters, systolic BP, low-density lipoprotein cholesterol (LDLC), triglyceride (TG) and high-density lipoprotein cholesterol (HDLC) were identified between wine and controls groups (fasting glucose [FG],WMD = -0.00, 95% CI: -0.58 to 0.58; fasting insulin [FI], -0.22, -2.09 to 1.65; HbAc1%, -0.16, -0.40 to 0.07; systolic blood pressure, 0.12, -0.05 to 0.28; LDLC, -0.02, -0.25 to 0.21; TG, -0.34, -1.31 to 0.64; HDLC, 0.22, -0.08 to 0.53]. CONCLUSION: This meta-analysis revealed that moderate wine consumption among T2DM patients could reduce the level of diastolic blood pressure and TC, but not glucose parameters and other cardiovascular risk factors.

RESUMO

Introduction: Diabetes is often accompanied by undiagnosed dyslipidemia. The aim of the study is to investigate the clinical relevance of lipid profiles and lipid ratios as predictive biochemical models for glycemic control in patients with type 2 diabetes mellitus (T2DM). Methods: This is a retrospective study recruiting 140 patients with T2DM during a one-year period, 2018-2019, at the Diabetic Center Sanglah General Hospital and Internal Medicine Polyclinic Puri Raharja General Hospital. Demographic characteristics, glycosylated hemoglobin (HBA1c) , and lipid profile were recorded and analyzed using SPSS version 25.0 for Windows. The sample is then classified into good (HBA1c≤7) and poor (HBA1c>7) glycemic control. Risk analysis model, receiver operator characteristics (ROC) analysis, and correlation test were used to evaluate the association of HBA1c level with lipid profile and lipid ratio parameters. Result: Lipid profile findings such as total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) , triglycerides (TG), and lipid ratio parameter (LDL-C to high-density lipoprotein cholesterol (HDL-C) ratio) were higher in patients in the poor glycemic control group (p<0.05) and HDL-C was significantly lower in patients with poor glycemic control (p=0.001). There is a significant positive correlation between LDL, total cholesterol, LDL-C, TG, and TC to HDL-C ratio, triglycerides, and TC/HDL-C ratio with HBA1c level. Meanwhile, a negative correlation was observed on HDL-C with the HBA1c level. Only TC/HDL-C ratio and LDL-C/HDL-C ratio parameters may be used as predictive models (AUC>0.7), with cutoff point, sensitivity, and specificity of 4.68 (77%; 52%) and 3.06 (98%; 56%) respectively. A risk analysis model shows that the LDL-C/HDL-C ratio parameter is the most influential risk factor in the occurrence of poor glycemic control (adjusted OR =38.76; 95% CI: 27.32-56.64; p<0.001). Conclusion: Lipid profiles (LDL-C) and lipid ratios (LDL-C/HDL-C and TC/HDL-C ratio) show potential markers that can be used in predicting glycemic control in patients with T2DM.

RESUMO

OBJECTIVE: To determine whether pre-hospital statin use is associated with lower renal replacement therapy requirement and/or death during intensive care unit stay. METHODS: Prospective cohort analysis. We analyzed 670 patients consecutively admitted to the intensive care unit of an academic tertiary-care hospital. Patients with ages ranging from 18 to 80 years admitted to the intensive care unit within the last 48 hours were included in the study. RESULTS: Mean age was 66±16.1 years old, mean body mass index 26.6±4/9kg/m2 and mean abdominal circumference was of 97±22cm. The statin group comprised 18.2% of patients and had lower renal replacement therapy requirement and/or mortality (OR: 0.41; 95%CI: 0.18-0.93; p=0.03). The statin group also had lower risk of developing sepsis during intensive care unit stay (OR: 0.42; 95%CI: 0.22-0.77; p=0.006) and had a reduction in hospital length-of-stay (14.7±17.5 days versus 22.3±48 days; p=0.006). Statin therapy was associated with a protective role in critical care setting independently of confounding variables, such as gender, age, C-reactive protein, need of mechanical ventilation, use of pressor agents and presence of diabetes and/or coronary disease. CONCLUSION: Statin therapy prior to hospital admission was associated with lower mortality, lower renal replacement therapy requirement and sepsis rates.

RESUMO

BACKGROUND: Insulin resistance, especially that induced by obesity, plays a central role in the development of non-alcoholic fatty liver disease. Although the evaluation of overweight patients is important, the nutritional assessment tools used in clinical practice have limitations. Neck circumference (NC), from this, becomes a viable and low-cost alternative, which seems to be related to the accumulation of fat in the hepatic tissue. OBJECTIVE: To evaluate the association between NC and metabolic alterations in patients with non- alcoholic fatty liver disease. METHODS: A cross-sectional study performed in 82 patients, of whom 76 underwent liver biopsy. We performed weight, height, abdominal circumference and NC measures. Values of NC ≥42 cm and ≥36 cm were considered as altered for men and women, respectively. Laboratory tests and liver biopsy result were collected in the participants' charts. We evaluated fasting blood glucose levels, insulin, glycosylated hemoglobin, triglycerides, total cholesterol, high density lipoprotein (HDL-C), low density lipoprotein (LDL-C), ferritin, alkaline phosphatase, gamma glutamyltransferase, albumin, total bilirubin, direct bilirubin, glutamic-oxalacetic transaminase, glutamic-pyruvic transaminase and the HOMA-IR index. RESULTS: We evaluated eighty-two patients. Patients with altered NC had increased body mass index (P=0.043), abdominal circumference (P=0.007), insulin (P=0.003) and HOMA-IR (P=0.029) when compared to those with adequate NC. NC was significantly correlated with reduced levels of high-density cholesterol (HDL-C) in men (r= -042, P<0.05), increased insulin levels in men and female (rs=0.47; P<0.05 and rs=0.51; P<0.01, respectively), as well as higher HOMA-IR index both males (rs=0.49; P<0.01) and female (rs=0.30; P<0.05). There was no significant association between NC and liver outcomes (r=0.145; P=0.36). CONCLUSION: NC is associated with the HOMA-IR index in patients with non-alcoholic fatty liver disease. NC can be used in the screening of insulin resistance in these patients, considering that insulin resistance plays a key role in the progression of the disease.

RESUMO

Hypertension is a complex disorder involving multiple organ systems and the primary modifiable risk factor for heart disease. Aim of the study was to assess the relationship of serum HDL-C and triglyceride with hypertensive patients in order to compare this parameter with normotensive subjects. This analytical type of cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2017 to June 2018. A total number of 120 male subjects, age ranged from 30-65 years was included in this study. Among them, sixty (60) hypertensive subjects were taken as study group (Group II) and sixty (60) ages matched normotensive male subjects were taken as control group (Group I). Data were expressed as mean±SD and statistical significance of difference among the group was calculated by unpaired student's 't' test. In this study we found that serum triglyceride and serum HDL cholesterol were significant in study group in comparison with control group. Therefore, by this study we recommended that routine estimation of these parameters is important for prevention of complication related to hypertension for leading a healthy life.
