Effect of Zinc Supplementation on Glycemic Control in Newly Diagnosed Patients With Type 2 Diabetes Mellitus.

Diabetes mellitus (DM) is a spectrum of metabolic disorders primarily characterized by elevated blood glucose levels. Type 2 DM (T2DM), the most common form, often requires adjunctive therapies to improve glycemic control and mitigate associated risks. Zinc has been implicated in glucose metabolism and insulin function, prompting this study to evaluate the impact of zinc supplementation on glycemic control in newly diagnosed T2DM patients. A randomized, placebo-controlled trial was conducted involving 80 newly diagnosed T2DM patients. Participants were randomly assigned to receive either zinc supplementation (50 mg/day) or a placebo, in conjunction with standard oral hypoglycemic medication, metformin. Key indicators, including fasting blood glucose (FBG), postprandial blood glucose (PPBG), hemoglobin A1c (HbA1c), and lipid profiles, were measured at baseline and after the 12-month intervention period. The group receiving zinc supplementation demonstrated significant reductions in FBG, PPBG, and HbA1c levels compared to the placebo group. The mean FBG in the intervention group decreased by 21.52 mg/dL, PPBG decreased by 47.53 mg/dL, and HbA1c decreased by 0.79%. Additionally, zinc supplementation led to notable decreases in low-density lipoprotein (LDL) cholesterol by 25.06 mg/dL, triglycerides by 22.2 mg/dL, and total cholesterol levels by 26.67 mg/dL. However, no significant changes were observed in high-density lipoprotein (HDL) cholesterol, very-low-density lipoprotein (VLDL) cholesterol, or erythrocyte sedimentation rate (ESR). The findings suggest that zinc supplementation may be a beneficial adjunctive therapy in the early management of T2DM, contributing to improved glycemic control and favorable changes in lipid profiles. However, its effect on HDL, VLDL, and ESR was insignificant, indicating the need for further research to better understand the broader implications of zinc in T2DM management.

Association Between the Triglyceride-Glucose Index and Serum Uric Acid to High-Density Lipoprotein (HDL) Cholesterol Ratio in Type 2 Diabetes Mellitus in Gabes City, Tunisia.

Background Type 2 diabetes mellitus (T2DM) is a significant risk factor for cardiovascular diseases (CVD). The triglyceride-glucoseindex (TyGi) is a novel biomarker for insulin resistance, strongly linked to CVD. Elevated serum uric acid levels and the uric acid to high-density lipoproteincholesterol ratio (UHR) are emerging as markers of metabolic syndrome and cardiovascular risk in T2DM. This study aimed to explore the association between the TyGiand UHR in T2DM patients. Objectives The aim of this study is to compare metabolic parameters in T2DM patients and assess the association between the TyGiand serum UHR. Methodology A cross-sectional case-control study was conducted at the University Hospital of Gabes, Gabes City, Tunisia with 50 T2DM patients and 50 gender-matched healthy controls. Inclusion criteria included adults aged 30-75 years with a confirmed diagnosis of T2DM on stable medication for at least three months. Exclusion criteria included other types of diabetes, significant liver or kidney disease, recent cardiovascular events, endocrine disorders, and substance abuse. Metabolic and biochemical parameters, including fasting blood sugar, postprandial blood sugar, glycosylated hemoglobin, lipid profile, and renal function, were measured. The TyGiand serum UHR were calculated and analyzed for correlations. Results T2DM patients exhibited significantly higher fasting blood sugar, postprandial blood sugar, glycosylated hemoglobin, TyGi, and serum UHR compared to controls, indicating impaired glycemic control and adverse lipid profiles. The UHR showed a positive correlation with a strong negative correlation with HDL and a positive correlation with uric acid levels. The linear regression analysis indicated a weak positive trend between the TyGi and serum UHR, although not statistically significant. Conclusion This study underscores the importance of the TyGiand serum UHRas biomarkers for evaluating metabolic and cardiovascular risk in T2DM. Further research is needed to explore their combined utility in clinical practice for early detection and management of cardiovascular complications in diabetic patients.

Assessment of Serum Omentin-1 and Interleukin-6 in the Diagnosis of Early Stages of Diabetic Nephropathy: A Cross-Sectional Observational Study.

Introduction The pathogenesis of diabetic nephropathy highlights the progression of inflammation and fibrosis from tubular to glomerular damage during the early stages of kidney involvement in diabetic individuals. As urine albumin serves as a marker for glomerular function, its detection indicates a stage of diabetic nephropathy where the glomerulus is already compromised. Consequently, relying solely on urine albumin for diagnosis becomes questionable. In our pursuit of identifying innovative biomarkers for the early detection of diabetic nephropathy, this study was crafted to explore the relationship between chemokines, omentin-1, interleukin-6, and microalbuminuria. Materials and methods Our study cohort comprised 116 patients diagnosed with diabetes mellitus. In our study, participants were stratified into two groups based on their urine albumin levels: Group 1, characterized by urine albumin creatinine ratio <30 mg/gm and estimated glomerular filtration rate >90 ml/min, and Group 2, with urine albumin creatinine ratio ≥30 mg/gm and <300 mg/gm, and estimated glomerular filtration rate >60 ml/min and <90 ml/min.Serum creatinine, glycated hemoglobin (HbA1c), fasting blood sugar and post-prandial blood sugar, lipid profile, total protein, albumin, fasting insulin, omentin-1, and interleukin-6 were estimated. Result There was a significant difference in the medians of serum urea, creatinine, omentin-1, interleukin-6, urine albumin creatinine ratio, and estimated glomerular filtration rate levels in the two groups. There was no difference in fasting blood sugar, post-prandial blood sugar,HbA1c, serum lipids, fasting insulin, and homeostatic model assessment for insulin resistance. The receiver operating characteristic curve plotted for the newer biomarkers of diabetic nephropathy showed that there was a significant diagnostic utility in diabetic nephropathy detection of serum omentin (p=0.000), interleukin-6 (p=0.002), and interleukin-6: omentin-1 ratio (p=0.000), which correlated well with the routine test that is urine microalbumin estimation. Risk assessment demonstrated that type 2 diabetes mellitus patients with an interleukin-6: omentin-1 ratio ≥0.26 had significantly higher odds, with an odds ratio of 3.97, for developing diabetic nephropathy, which was statistically significant. Conversely, a ratio of ≤0.26 was associated with kidney protection among patients with type 2 diabetes mellitus. Conclusion Our findings revealed decreased levels of omentin-1 and increased levels of interleukin-6 in the group with diabetic nephropathy compared to those without diabetic nephropathy among patients with type 2 diabetes mellitus. Interleukin-6: omentin-1ratio of ≤0.26 was associated with kidney protection among patients with type 2 diabetes mellitus. Based on the results obtained from this study, we propose that measuring the serum interleukin-6: omentin-1 ratio in patients with type 2 diabetes mellitus may assist in identifying the early stages of diabetic nephropathy before the onset of microalbuminuria. Timely intervention in these patients predisposed to diabetic nephropathy can aid in better treatment outcomes in type 2 diabetes mellitus.

Diacylglycerol oil on metabolic syndrome: A Review

The metabolic syndrome is a trait of metabolic disorders that results from the increasing prevalence of obesity. Clinical manifestations include insulin resistance, hyperlipidemia, hyperuricemia, etc. Populations with high morbidity tend to be middle-aged and elder adults. With the advent of an ageing society, the incidence of metabolic syndrome will be higher. Since diacylglycerol (DAG) oil was first introduced in 1999, it has received extensive attention. DAG oils and related products have been distributed in markets in Japan, Europe, and the United States since 2001. This paper will review the effects of the new dietary oil, DAG, on the metabolic syndrome. It is hoped that DAG oil has the ability to replace traditional triacylglycerol (TAG) oil and control the morbidity of metabolic syndrome. This review article collected recent studies, and the results proved that dietary DAG is effective for reducing postprandial blood lipids and blood glucose, managing weight, and ameliorating insulin sensitivity.

Changes in the chronic and postprandial blood lipid profiles of trained competitive cyclists and triathletes following a ketogenic diet: a randomized crossover trial

BackgroundThe ketogenic diet (KD) is the most popular carbohydrate restriction strategy for endurance athletes. However, because the primary goal of employing the KD is to gain a competitive advantage in competition, endurance athletes may be less concerned with the influence of the KD on their cardiometabolic health; particularly their blood lipid profiles. Thus, the purpose of this study was to examine the chronic and postprandial blood lipid alterations following a two-week ad libitum KD compared to an ad libitum high-carbohydrate diet (HCD) and the athletes’ habitual diet (HD) in a group of trained competitive cyclists and triathletes.MethodsSix trained competitive cyclists and triathletes (female: 4, male: 2; age: 37.2 ± 12.2) completed this randomized crossover trial, which required them to follow a two-week ad libitum KD and HCD in a randomized order after their HD. Fasting blood lipids were collected following their HD and after two-weeks of the KD and HCD conditions. Postprandial blood lipid responses to a test meal reflective of the assigned diet were collected at the end of each diet condition.ResultsFasting total cholesterol (TC) was significantly higher following the KD compared to the HD (p < 0.001) and HCD (p = 0.006). Postprandial incremental area under the curve for triglycerides (TRG), TRG:HDL ratio, and VLDL-C were significantly higher following the KD test meal compared to the HD (all p < 0.001) and HCD (all p = 0.001) test meals but LDL-C and LDL:HDL ratio were significantly lower following the KD compared to the HD and HCD test meals (all p < 0.001).ConclusionsTrained competitive cyclists and triathletes demonstrate increased TC in response to a two-week KD compared to a HCD or HD. Endurance athletes contemplating a KD should consider the potential for these blood lipid alterations, and future research should focus on postprandial blood lipid responses to determine if these changes manifest in chronic blood lipid shifts.Trial registrationClinicalTrials.gov Identifier: NCT04097171 (11 October 2019).

Relation between 25-hydroxy vitamin D and diabetic retinopathy in Egyptian patients with type 2 diabetes mellitus

Background/aim Diabetic retinopathy (DR) is one of the leading causes of blindness in people whose ages range from 20 to 64 worldwide. This study aims to evaluate the association of serum 25-hydroxy (OH) vitamin D deficiency and DR in type 2 diabetes mellitus (T2DM) patients. Patients and methods A cross-sectional study was conducted on 90 Egyptian patients with T2DM. Patients were divided into two groups: group I included 44 patients without retinopathy and group II included 46 with retinopathy. Group II was subdivided into two subgroups, group IIa, which included 26 nonproliferative DR patients and group IIb, which included 20 proliferative DR patients. Anthropometric data and laboratory investigations, including fasting and the postprandial blood sugar, glycated hemoglobin, lipid profiles, and serum vitamin D level. A fundus examination was also performed. Results The present results exhibited a significant decrease (P&lt;0.05) of serum vitamin D (25-OH-vitamin D) in patients with T2DM and this deficiency is more in group II in comparison to group I and in a patient with proliferative DR (group IIb) compared to nonproliferative DR (group IIa). Also, there was a downward trend in serum vitamin D with the severity of DR. Also 25-OH-vitamin D level was inversely correlated with fasting, postprandial blood sugar, and glycated hemoglobin. A cut-off value for serum vitamin D levels of less than or equal to 12.03 ng/ml served as a sensitive indicator for DR. Conclusion 25-OH-vitamin D deficiency is highly prevalent in Egyptian patients with T2DM and this deficiency is highly associated with the presence and severity of DR.

Effects of mulberry twig alkaloids(Sangzhi alkaloids) and metformin on blood glucose fluctuations in combination with premixed insulin-treated patients with type 2 diabetes.

We aimed to evaluated the effect of premixed insulin (Ins), premixed insulin combined with metformin (Ins+Met) or mulberry twig alkaloids(Ins+SZ-A) on blood glucose fluctuations in patients with type 2 diabetes (T2DM) using continuous glucose monitors (CGM). Thirty patients with T2DM and poor blood glucose control using drugs were evaluated for eligibility during the screening period. Subsequently, their original hypoglycemic drugs were discontinued during the lead-in period, and after receiving Ins intensive treatment for 2 weeks, they were randomly assigned to receive either Ins, Ins+Met, or Ins+SZ-A treatment for the following 12 weeks. The main efficacy endpoint comprised changes in their CGM indicators changes (mean blood glucose level [MBG], standard deviation of blood glucose [SDBG], mean amplitude of glycemic excursions [MAGE], postprandial glucose excursions [PPGE], the largest amplitude of glycemic excursions [LAGE], mean of daily difference [MODD], time in range between 3.9-10.0 mmol/L [TIR] and area under the curve for each meal [AUCpp]) during the screening, lead-in, and after 12-week treatment period. Changes in glycosylated hemoglobin (HbA1c), fasting blood glucose (FBG), 1-h postprandial blood glucose (1h-PBG), 2-h postprandial blood glucose (2h-PBG), fasting blood lipids and postprandial blood lipids were also measured at baseline and after 12 weeks of treatment. The CGM indicators of the three groups during the lead-in period all showed significant improvements compared to the screening period (P<0.05). Compared with those in the lead-in period, all of the CGM indicators improved in the the Ins+Met and Ins+SZ-A groups after 12 weeks of treatment (P<0.05), except for MODD. After 12-week treatment, compared with the Ins group, Ins+Met and Ins+SZ-A groups showed improved MBG, SDBG, TIR, breakfast AUCpp,lunch AUCpp, HbA1c, FBG, 1h-PBG, fasting blood lipid and postprandial blood lipid indicators (P<0.05). Further, the LAGE, PPGE, MAGE, dinner AUCpp and 2h-PBG levels of the Ins+SZ-A group were significantly lower than those of the Ins+Met and Ins groups (P<0.05). Our findings highlight the efficacy of combination therapy (Ins+SZ-A or Ins+Met) in improving blood glucose fluctuations, as well as blood glucose and lipid levels. Ins+SZ-A reduces postprandial blood glucose fluctuations more than Ins+Met and Ins groups. ISRCTN20835488.

Postprandial glycemic and lipidemic effects of black rice anthocyanin extract fortification in foods of varying macronutrient compositions and matrices

Anthocyanin (ACN) fortification of commonly consumed foods is significant as a dietary strategy against the development of metabolic complications by delivering ACNs at high doses. However, its bioactivity and translated metabolic effects in the presence of varying food matrices and macro-constituents is particularly unclear. This end-to-end study investigates the metabolic effects of black rice ACN extract (BRAE) fortification—from in-vitro enzyme inhibitory activities and digestibility, to downstream in vivo impacts on GI, postprandial glycemia and lipidemia. The in vivo effects were investigated in two separate crossover randomised controlled trials (RCT) of 24 healthy participants each—the first RCT determined the postprandial blood glucose, insulin, and ACN bioavailability to a starch-rich single food over 2 h, while the second RCT determined the postprandial blood glucose, insulin, lipid panel, and lipoprotein particles and subfractions to a starch- and fat-rich composite meal over 4 h. In-vitro findings confirmed the inhibitory activities of major black rice ACNs on carbohydrases (p = 0.0004), lipases (p = 0.0002), and starch digestibility (p < 0.0001). in vivo, a 27-point mean GI reduction of wheat bread was observed with BRAE fortification, despite a non-significant attenuation in postprandial glycemia. Conversely, there were no differences in postprandial glycemia when fortified bread was consumed as a composite meal, but acute lipid profiles were altered: (1) improved plasma HDL-c, ([0.0140 mmol/L, 95% CI: (0.00639, 0.0216)], p = 0.0028), Apo-A1 ([0.0296 mmol/L, 95% CI: (0.00757, 0.0515)], p = 0.0203), and Apo-B ([0.00880 mmol/L, 95% CI: (0.00243, 0.0152)], p = 0.0185), (2) modified LDL and HDL subfractions (p < 0.05), and (3) remodelled lipid distributions in HDL and LDL particles. This end-to-end study indicates the potential of ACN fortification in GI reduction and modulating postprandial lipoprotein profiles to starch- and fat-rich composite meals.

Effect of Structured Yoga Program on Stress and Well-being Among Frontline Healthcare Workers During COVID-19 Pandemic.

Frontline healthcare workers are at risk of developing psychological distress during a pandemic. Yoga, a form of mind-body medicine can reduce body stress and increases well-being. To assess the effect of yoga on the stress and well-being of healthcare workers during the COVID-19 pandemic. This single-arm pre-post study was conducted among frontline health workers (support staff, paramedics, and medics) posted at a secondary care hospital in a North Indian district. Basic demographic details, blood pressure, anthropometric variables like height, weight, and biochemical variables like glycosylated hemoglobin (Hb1Ac), fasting and post-prandial blood sugar, lipid profile, serum cortisol, and C-reactive protein were measured. Stress levels were assessed using the depression anxiety and stress scale (DASS)-21 while well-being was assessed using the World Health Organization (WHO)-5 well-being scale.Twelve weeks of supervised yoga session was provided for 1 hour per session, 3 times per week. The mean value was compared from baseline to post-intervention with paired t-test/Wilcoxon signed rank test. A total of 89 participants were enrolled, 53 (59.5%) being male. Two-thirds of the participants were aged 20-39 years. During follow-up, 80 participants completed 12 weeks of yoga sessions. Post-intervention DASS-21 score decreased and WHO-5 increased significantly. The glycosylated hemoglobin (HbA1c) level and cholesterol-HDL ratio decreased significantly. Other variables didn't change significantly. No adverse effects were reported by the participants. Supervised structured yoga sessions helped decrease stress, depression, and anxiety and improved well-being. Therefore, it can be a feasible strategy to manage workplace-related stress and phycological morbidities.

Biochemical Correlation of Sex Hormone Profile with Diabetes Mellitus Type 2 In Indian Men- A Case-Control Study

Introduction: India, the country with the highest prevalence of diabetes, has between 62,4 and 77,2 million diabetics and pre-diabetics. The purpose of this study was to investigate the biological correlation between sex hormone profile and type 2 diabetes in Indian men.&#x0D; Methodology: In this case-control study, total of 181 diabetic cases and 181 healthy controls were enrolled as per WHO norms. Along with clinic-demographical data, fasting blood glucose, Postprandial blood glucose, HBA1c, insulin, lipid profile and Testosterone, LH, FSH were measured and compared.&#x0D; Results: A non-significant difference was observed [p=0.7831] between different ages among the study population's case and control groups. The FPG, HbA1c, total cholesterol, LDL, triglycerides were significantly elevated in cases as compared to controls, except HDL and SHBG, showing non-significant differences. The spearman correlation between Testosterone and different parameters, and all the correlations showed a significant negative correlation. However, Testosterone Vs. Testicular Volume (ml) [r=0.2981], Testosterone Vs. HDL cholesterol(mmol/l) [r=0.04884] and Testosterone Vs. Calculated Free Testosterone (mmol/L) [r=0.007494] respectively shows significant positive correlation.&#x0D; Conclusion: Type 2 Diabetes male patients had lower testosterone levels. As a biomarker for Type 2 Diabetes, it is possible to measure changes in serum testosterone levels.

A study on serum ferritin, C-reactive protein, and its correlation with HBA1c in type 2 diabetes mellitus

Abstract Introduction: Diabetes mellitus is a multifaceted metabolic disorder with impaired glucose status in the human body relative to insulin deficiency. Resistance to its action causes impaired glucose tolerance and hyperglycemia. Serum ferritin and C-reactive protein (CRP) are acute-phase reactants correlated with glycated haemoglobin (HBA1c) in a diagnosed diabetic patient as chronic inflammatory markers. Aim: The study aimed to study the relationship between HBA1c in diabetes patients and inflammatory markers such as serum ferritin and CRP. Materials and Methods: The study group comprised 106 subjects who met the criteria of type 2 diabetes mellitus, an age group between 30 and 90, involving both genders; inclusion and exclusion criteria were added to the study group. Fasting blood sugar, postprandial blood sugar, HBA1c, urine routine, lipid profile, serum ferritin, and CRP were assessed in all study subjects. Data were statistically analyzed and compared the relationship among HBA1c, serum ferritin, and CRP. Results: In this study, 31.1% constituted the age group between 50 and 60. A total of 51.9% were males. A total of 64.2% were on oral hypoglycaemics, and 18% had urine albumin on examination. On Spearman’s rho correlation between serum ferritin and HbA1c, the r value is 0.011, and the P value is 0.911 having a positive correlation. On Spearman’s rho correlation between CRP and HbA1c, the r value is 0.017, and the P value is 0.865 showing a positive correlation. Conclusion: In this study, inflammatory indicators, including serum ferritin and CRP levels, have a positive correlation with HbA1c values, though statistically not significant, showing higher HbA1c values with elevated serum ferritin and CRP levels. Raised inflammatory markers suggest a chronic inflammatory process in a condition or disease such as diabetes mellitus. By measuring these parameters, we can discover essential aspects of screening, the course of diabetes, its complications, and prevention.

Elevated postprandial triglyceride-rich lipoproteins in patients with diabetes and stable coronary artery disease correlated with early renal damage and systemic inflammation

BackgroundDyslipidaemia is key in the development of coronary heart disease (CHD) in patients with diabetes mellitus (DM). Accumulated evidence supports that diabetic nephropathy increases the mortality risk of patients with CHD, while the influence of diabetic dyslipidaemia on renal damage in patients with DM and CHD remains unknown. Moreover, recent data indicate that postprandial dyslipidaemia has predictive value in terms of CHD prognosis, especially in patients with DM. The study aimed to determine the relationship of triglyceride-rich lipoproteins (TRLs) after daily Chinese breakfast on systemic inflammation and early renal damage in Chinese patients with DM and SCAD.MethodsPatients with DM diagnosed with SCAD while in the Department of Cardiology of Shengjing Hospital from September 2016 to February 2017 were enrolled in this study. Fasting and 4-h postprandial blood lipids, fasting blood glucose, glycated haemoglobin, urinary albumin-to-creatinine ratio (UACR), serum interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) concentrations, and other parameters were measured. Fasting and postprandial blood lipid profiles and inflammatory cytokines were analysed using a paired t-test. The association between variables was analysed using Pearson or Spearman bivariate analysis. P < 0.05 was considered to be statistically significant.ResultsThe study enrolled 44 patients in total. Compared with fasting state, postprandial total cholesterol high-density lipoprotein-cholesterol (HDL-C),low-density lipoprotein-cholesterol (LDL-C) and non-high-density lipoprotein-cholesterol (non-HDL-C) all showed no significant change. Postprandial serum triglyceride (TG) concentration increased significantly compared with that at fasting (1.40 ± 0.40 vs. 2.10 ± 0.94 mmol/L, P < 0.001), as did serum remnant lipoprotein-cholesterol (RLP-C) (0.54 ± 0.18 mmol/L vs. 0.64 ± 0.25 mmol/L). Pearson analysis revealed that serum TG and RLP-C positively correlated before and after breakfast. Moreover, during fasting, positive correlations were observed between TG and serum IL-6, TNF-α, and UACR. Positive correlations were observed between RLP-C and IL-6, UACR under fasting condition, while both TG and RLP-C were positively correlated with postprandial serum IL-6, TNF-α, and UACR concentrations. Finally, positive correlations were observed between UACR and IL-6 and TNF-α concentration under both fasting and postprandial conditions.ConclusionsAn increase in postprandial TRLs was observed in Chinese patients with DM and SCAD after daily breakfast, and this increase may be related to early renal injury via the induction of systemic inflammation.

Comparison between Fasting and Non-Fasting Cut-Off Values of Triglyceride in Diagnosing High Triglyceride in Chinese Hypertensive Outpatients

Background: Hypertension (HBP) often occurs together with hypertriglyceridemia which indicates elevated triglyceride (TG) and remnant cholesterol (RC) levels. Non-fasting (i.e., postprandial) blood lipid test after a daily meal has been recommended by the European Atherosclerosis Society (EAS). However, little is known about the difference between fasting and non-fasting cut-off values in assessing high TG (HTG) and high RC (HRC) in HBP outpatients. Methods: 225 Chinese outpatients with HBP, including 119 fasting patients (i.e., fasting group) and 106 non-fasting patients (i.e., non-fasting group) were enrolled in this study. Non-fasting levels of blood lipids at 2 h after a daily breakfast were also tested in 33 patients among the fasting group. Venous blood samples were collected. Results: The non-fasting group had significantly higher levels of TG and RC while lower levels of total cholesterol, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol than the fasting group (p < 0.05). According to the TG and RC cut-off values of the EAS, the percentages of HTG and HRC in the non-fasting group were 72.6% and 70.8%, respectively, whereas those in the fasting group were 57.1% and 52.9%, respectively. According to the cut-off value of marked HTG commonly used in the Chinese population in clinical practice, the percentage of marked HTG in the non-fasting group was 57.5%, whereas that in the fasting group was 34.5%. However, the percentages of HTG (57.6% vs. 51.5%) and HRC (51.5% vs. 51.5%) marked HTG (30.3% vs. 33.3%) in the fasting state and at 2 h after a daily breakfast in 33 outpatients did not reach statistical significance. Conclusion: Non-fasting blood lipid tests could find more individuals with HTG as well as those with marked HTG among Chinese outpatients with HBP. It indicates that non-fasting blood lipid tests are worth being recommended in patients with HBP.

Pea Fiber Lowers Fasting and Postprandial Blood Triglyceride Concentrations in Humans ,

The effect of a pea cell wall fiber preparation with a high content of soluble fiber on fasting and postprandial blood lipids was investigated in young healthy subjects. Inclusion of 33 g pea fiber product/10 MJ (20 g dietary fiber) in a low fiber diet was tested in five men and six women (mean age 23 y) in a strictly controlled randomized cross-over intervention study over 2 wk separated by a 2-wk period of habitual diet consumption. No significant differences in fasting concentrations of total cholesterol, LDL cholesterol or HDL cholesterol were observed, whereas total and VLDL triglyceride concentrations were lower when subjects consumed the pea fiber diet compared with the low fiber diet (P < 0.05). Postprandial response to pea fiber was studied in eight men. Addition of 12 g pea fiber product/ 10 MJ to a breakfast meal and 15 g/10 MJ to the following lunch meal resulted in significantly lower total triglyceride (P = 0.01), chylomicron triglyceride (P = 0.03) and insulin (P = 0.003) concentrations after the lunch meal compared with results following the same meal without pea fiber. No differences were observed in glycemic response. In conclusion, this source of dietary fiber lowered fasting and postprandial triglyceride concentrations but did not change fasting cholesterol concentrations.

Pecan-enriched diet improves cholesterol profiles and enhances postprandial microvascular reactivity in older adults

Pecan-enriched diets have been linked to improved lipid metabolism; however, the impact of pecans on vascular health has yet to be examined. We hypothesized that 4 weeks of a pecan-enriched diet would improve fasting and postprandial blood lipids and vascular function compared with a nut-free diet. In this randomized control study, 44 older adults (59 ± 6 years) consumed 68 g of pecans/d (pecan; n = 21) or avoided all nuts (control; n = 23) for 4 weeks. At pre- and post-diet visits, fasting and postprandial blood lipids, macrovascular (by flow-mediated dilation), and microvascular (tissue saturation index reactive hyperemia [RH] kinetics by continuous-wave near-infrared spectroscopy) function were assessed. From the pre- to post-diet visit, there were greater reductions in fasting total cholesterol (pecan: –14 ± 4.0 vs control: –0.2 ± 5.4 mg/dL; P = .04), low-density lipoprotein (LDL) cholesterol (pecan: –15 ± 3.7 vs control: +1.9 ± 4.4 mg/dL; P = .01), non–high-density lipoprotein cholesterol (pecan: –15 ± 3.6 vs control: –0.5 ± 4.8 mg/dL; P = .02), LDL particle number (pecan: –126 ± 51 vs control: +43 ± 42 nmol/L; P = .01), and LDL medium (pecan: –34 ± 13 vs control: +16 ± 11 nmol/L; P < .01), for pecan vs control. Further, postprandial triglyceride was suppressed for pecan (P = .01) compared with control (P = .78). Postprandial RH slope (P = .04) and RH time to half (P = .004) was different by group, driven by improvements in pecan vs control. However, fasting macro- and microvascular function was unaffected. Daily pecan consumption for 4 weeks improved fasting and postprandial blood lipids and microvascular reactivity in older adults. Because changes in microvascular function typically precipitate macrovascular changes, long-term pecan consumption may improve vascular health and reduce risk for cardiovascular events. This trial was registered at clinicaltrials.gov (NCT04385537).

Left Ventricular Diastolic Dysfunction in Patients with Type 2 Diabetes Mellitus and its Association with Age, Gender, Duration and Glycosylated Haemoglobin: A Cross-sectional Study

Introduction: Diabetes Mellitus (DM) is a group of metabolic disorders resulting in hyperglycaemia with disturbances in carbohydrate, fat, and protein metabolism. Hyperglycaemia when present for a long period of time leads to a host of metabolic abnormalities and also results in end organ damage. Diastolic dysfunction is an early sign of diabetic heart muscle disease preceding systolic and diastolic damage. Only a few studies have been conducted in central India to establish this prevalence and association in diabetic patients. Aim: To assess Left Ventricular Diastolic Dysfunction (LVDD) in diabetic patients and its association with age, gender, duration, and glycosylated haemoglobin (HbA1c). Materials and Methods: In this cross-sectional study, 150 normotensive patients with type 2 DM and no clinical evidence of cardiovascular disease were enrolled by simple random selection in the Department of General Medicine, Shyam Shah Medical College, Rewa, Madhya Pradesh, India. The sample size was calculated by standard formula with a confidence interval of 95% and an error margin of less than 5%. A semi-structured proforma was used to record the demographic profiles with full medication history, as well as, anthropometric measurements like height, weight, and waist circumference. Blood pressure was measured and blood was drawn for complete blood count, liver function test, renal function test, fasting and postprandial blood sugar, HbA1c, and lipid profile. Electrocardiographic and Echocardiographic studies were performed to assess LVDD. Data obtained by various methods was analysed statistically using Statistical Package for the Social Sciences (SPSS), version 20.0 and Chi-square test. Results: The present study showed that 85 out of 150 types 2 diabetic patients had diastolic dysfunction, out of which 80 had grade I diastolic dysfunction and, five of them had grade II diastolic dysfunction. The prevalence of diastolic dysfunction was increased with age, duration, and HbA1c (≥7%) and was not affected by gender. Conclusion: The study concluded that asymptomatic normotensive patients of type 2 DM have Heart Failure with preserved Ejection Fraction (HFpEF). LVDD were associated with age, gender, duration of diabetes, and HbA1c.

Impact of Atorvastatin on C-reactive Protein, Glycaemic Status and Liver Enzymes among Non Diabetic Patients: A Prospective Study

Introduction: Atorvastatin is one of the common drugs used for primary and secondary prevention of atherosclerotic cardiovascular diseases. Various studies have suggested variation in C-reactive Protein (CRP) value, glycaemic status and liver enzymes of patients following statin therapy. However, the adequate and exact data regarding the impact of atorvastatin on the above parameters in the population of Eastern India is still limited. Aim: To estimate the effect of atorvastatin on CRP, glycaemic status and haepatic enzymes of non diabetic patients. Materials and Methods: A prospective longitudinal observational study was conducted in the Outpatient Department (OPD) of Internal Medicine at Midnapore Medical College and Hospital, Paschim Medinipur, West Bengal, India. The duration of the study was one year six months, from June 2020- December 2021. A total of 150 non diabetic patients aged between 30- 75 years receiving atorvastatin were enrolled in the present study. Patients with known Diabetes Mellitus (DM), impaired fasting glucose, impaired glucose tolerance, pregnancy and lactation were excluded. CRP, Fasting Blood Sugar (FBS), Postprandial Blood Sugar (PPBS), haepatic enzymes and lipid profile of participants were monitored at baseline, at the end of one month, six months and 12 months. The data was analysed using Statistical Package for Social Sciences (SPSS) version 22.0, Microsoft Excel and GraphPad Prism. Results: The study population were predominantly males (69.6%), with mean age of 54±8.88 years and mean weight of 60±5.86 kg. Majority of the patients were on atorvastatin 40 mg (60.86%) followed by atorvastatin 20 mg (26.8%) and atorvastatin 10 mg (12.3%). There were statistical significant changes of mean CRP (1.502 mg/L), mean FBS (86.52 mg/dL), mean PPBS (113.57 mg/dL), mean Serum Glutamic-oxaloacetic Transaminase (SGOT) (22.84 IU/L), mean Serum Glutamic Pyruvic Transaminase (SGPT) (25.24 IU/L) and lipid profile levels at the end of one year. None of the patients developed new onset DM at the end of one year. A 5% of patients developed prediabetes at the end of 3rd follow-up. Conclusion: Atorvastatin usage showed that, there was a significant increase in blood glucose and haepatic enzymes level in non diabetic population. Hence, strict monitoring of blood glucose levels along with periodic monitoring of haepatic enzyme levels should be done in regular intervals.

Characteristics of Gut Microbiota in Female Patients with Diabetic Microvascular Complications.

To explore the characteristics and analyze the gut microbiota in female patients with diabetic microvascular complications (DMC). Thirty-seven female patients with type 2 diabetes mellitus (T2DM) were included in the study. These patients were divided into DM group with microvascular complications (T2DM-MC, n = 17) and no microvascular complications group (T2DM-0, n = 20). Patients in the microvascular group presented with the involvement of at least one of the following: kidney, retinal, or peripheral nerves. Using real-time fluorescence quantitative polymerase chain reaction, fecal samples from the two groups were tested for Bacteroides, Prevotella, Bifidobacterium spp, Lactobacillus, Faecalibacterium prausnitzii, Enterococcus spp, Eubacterium rectale, Veillonellaceae, Clostridium leptum, and Roseburia inulinivorans. Levels of fasting and 2 h postprandial blood glucose, glycosylated hemoglobin (HbA1c), lipids, and creatinine were determined to explore the correlation between gut microbiota and blood sugar. Mann-Whitney U test was used to analyze the differences between the two groups. Spearman correlation analysis was used to determine the correlation between gut microbiota and blood glucose. Multifactor logistic regression was used to analyze the risk factors for DMC. The HbA1c levels in the T2DM-MC group were higher than those in the T2DM-0 group. The abundances of Bacteroides and Enterococcus spp in the T2DM-MC group were higher than that in the T2DM-0 group. The abundances of Bacteroides and Enterococcus spp in the T2DM-MC group were lower than that in the T2DM-0 group. Spearman's correlation analysis showed that Bacteroides, Prevotella, Lactobacillus, C. leptum, and R. inulinivorans were related to the levels of HbA1c or blood glucose (p < 0.05). Logistic regression analysis showed that after adjusting for confounding factors such as age, body mass index, family history, HbA1c, hypertension, dyslipidemia, and creatinine, Bacteroides remained an independent risk factor in female patients with DMC. Gut microbiota is related to blood glucose levels. Female patients with DMC experience gut microbiota disorders. The abundances of Bacteroidesare related to DMC, and the abundances of intestinal flora may affect the blood sugar levels of the body.

Blood Lipid Responses to Diets Enriched with Cottonseed Oil Compared with Olive Oil in Adults with High Cholesterol in a Randomized Trial

BackgroundIncreasing unsaturated fat intake is beneficial for cardiovascular health, but the type of unsaturated fat to recommend remains equivocal. ObjectivesWe investigated the effects of an 8-week diet intervention that was rich in either cottonseed oil (CSO; PUFA rich) or olive oil (OO; MUFA rich) on blood lipids in hypercholesterolemic adults. MethodsForty-three men and women with hypercholesterolemia (53 ± 10 years; BMI, 27.6 ± 4.8 kg/m2) completed this randomized parallel clinical trial consisting of an 8-week partial outpatient feeding intervention. Participants were given meals and snacks accounting for ∼60% of their daily energy needs, with 30% of energy needs from either CSO (n = 21) or OO (n = 22). At pre- and postdiet intervention visits, participants consumed a high-SFA meal (35% of total energy needs; 70% of energy from fat). The primary outcomes of fasting cholesterol profiles and secondary outcomes of postprandial blood lipids and glycemic markers were assessed over a 5-hour period. ResultsThere were greater reductions from baseline to week 8 in fasting serum total cholesterol (TC; −17.0 ± 3.94 mg/dL compared with −2.18 ± 3.72 mg/dL, respectively; P = 0.008), LDL cholesterol (−19.7 ± 3.94 mg/dL compared with −5.72 ± 4.23 mg/dL, respectively; P = 0.018), non–HDL cholesterol (−20.8 mg/dL ± 4.00 compared with −6.61 ± 4.01 mg/dL, respectively; P = 0.014), and apoB (−11.8 mg/dL ± 2.37 compared with −3.10 ± 2.99 mg/dL, respectively; P = 0.05), in CSO compared with OO. There were also visit effects from baseline to week 8 for increases in HDL cholesterol (CSO, 56.5 ± 2.79 mg/dL to 60.2 ± 3.35 mg/dL, respectively; OO: 59.7 ± 2.63 mg/dL to 64.1 ± 2.24 mg/dL, respectively; P < 0.001), and decreases in the TC:HDL-cholesterol ratio (CSO, 4.30 ± 0.27 mg/dL to 3.78 ± 0.27 mg/dL, respectively; OO, 3.94 ± 0.16 mg/dL to 3.57 ± 0.11 mg/dL, respectively; P < 0.001), regardless of group assignment. In response to the high-SFA meal, there were differences in postprandial plasma glucose (P = 0.003) and triglyceride (P = 0.004) responses and a trend in nonesterified fatty acids (P = 0.11) between groups, showing protection in the postprandial state from an occasional high-SFA fat meal with CSO, but not OO, diet enrichment. ConclusionsCSO, but not OO, diet enrichment caused substantial improvements in fasting and postprandial blood lipids and postprandial glycemia in hypercholesterolemic adults. This trial was registered at clinicaltrials.gov as NCT04397055.
