Background: In previous study, we found that coenzyme Q10 (CoQ10) improved glucolipid profile in dyslipidemic individuals, but the mechanism is not yet clear. Adipokines have been demonstrated to be vital targets of metabolic diseases. The hypothesis that adipokines mediate the association of CoQ10 on glucolipid metabolism needs to be further studied in human. Methods: In this randomized, double-blinded, placebo-controlled trial, 101 dyslipidemic individuals were administrated to 120 mg CoQ10 or placebo for 24 weeks. Anthropometric parameters, glucolipid profile, serum total adiponectin, leptin, and resistin were evaluated at baseline, week 12 and week 24. Results: CoQ10 treatment significantly increased serum adiponectin levels at week 12 (165 [0, 362] ng/mL, p < 0.001) and at week 24 (523 [0, 1056] ng/mL, p < 0.001]), which was significant different compared with placebo (p < 0.001). The increase of adiponectin was negative associated with decrease in index of homeostasis model assessment of insulin resistance (HOMA-IR, r = − 0.465, p = 0.001), triglyceride (TG, r = − 0.297, p = 0.047), and low-density lipoprotein cholesterol (LDL-c, r = − 0.440, p = 0.002) at week 24 only in CoQ10-treated group. Resistin was reduced by CoQ10 only at week 24 (− 1.19 [− 4.35, 0.00] ng/mL, p < 0.001), which was significant different compared with placebo (p < 0.001). Reduction of resistin was positively correlated with the change in HOMA-IR (r = 0.343, p = 0.021) and TG (r = 0.323, p = 0.030) at week 24 in CoQ10-treated group but not placebo group. Leptin was not influenced by CoQ10 treatment. Mediation analysis indicated that the improvement of HOMA-IR, TG and LDL-c by CoQ10 was mediated by adiponectin but not resistin. Conclusions: Our study shows that CoQ10 ameliorates glucolipid profile and adipokines dysfunction in dyslipidemic patients in 24 weeks' intervention. The beneficial effect of CoQ10 on glucolipid profile was mediated by adiponectin. Trial registration: ClinicalTrials.gov, NCT02407548.

Background: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders among women of reproductive age. This study was designed to investigate the effects of melatonin and/or magnesium supplementation on metabolic profile and levels of sex hormones in PCOS women. Methods: In an 8-week randomized double-blind placebo-controlled trial, 84 subjects with PCOS aged 18-40 years were randomly assigned based on the random block procedure to take magnesium, melatonin, magnesium plus melatonin, and placebo. Fasting blood samples were obtained at the beginning and end of the study. Results: After intervention, the mean Pittsburg Sleep Quality Index score decreased significantly in both co-supplementation and melatonin groups (P < 0.001). Magnesium supplementation in combination with melatonin resulted in a significant greater decrease in testosterone concentrations compared with the placebo (P < 0.05). Co-supplementation of magnesium-melatonin had significantly reduced serum insulin levels (geometric means difference: -1.11 (mIU/mL) (percent change: -15.99)), homeostasis model of assessment-insulin resistance (HOMA-IR) (-0.28 (-18.66)), serum cholesterol (mean difference: -16.08 (mg/dl) [95% CI -24.24, -7.92]), low-density lipoprotein cholesterol (LDL-C) -18.96 (mg/dl) [-28.73, -9.20]) and testosterone levels (-0.09 (ng/ml) (-25.00)), as compared to the baseline values (P < 0.05). An increase in serum high-density lipoprotein cholesterol (HDL-C) levels was also observed following the administration of the melatonin alone (2.76 (mg/dl) [0.57, 4.95]) or in combination with magnesium (2.19 (mg/dl) [0.61, 3.77]) (P < 0.05). Conclusions: Co-supplementation with magnesium and melatonin had beneficial effects on sleep quality and total testosterone. Additionally, melatonin supplementation alone was found to be associated with a significant reduction in PSQI score. Moreover, combined melatonin and magnesium supplementation was more effective in improving serum levels of cholesterol, LDL-C, HDL-C and insulin, and HOMA-IR. [ABSTRACT FROM AUTHOR]

Background: Elevated cholesterol levels and systemic inflammation are considered relevant risk factors for cardiovascular disease (CVD) development and progression. Increasing evidence suggests that cholesterol-lowering and inflammation-lowering nutraceuticals are useful in the management of moderate hypercholesterolemia. Here, we describe the study protocol of a clinical trial aimed to evaluate the cholesterol and inflammatory lowering effect of an innovative dietary supplement (BruMeChol™, Mivell S.r.l., Italy), composed of a mixture of extracts of bergamot and olive fruits in association with vitamin K2 in subjects with mild hypercholesterolemia.Methods: The study was planned as a randomized, double-blind, placebo-controlled, parallel group clinical trial for 12 weeks at the Cardiology Unit of the IRCCS INRCA of Ancona, Italy. A total of 125 subjects (age ≥ 40 years) with mild hypercholesterolemia (total serum cholesterol levels ≥ 200 and ≤ 250 mg/dl) will be recruited. Intervention arm participants will take one capsule of dietary supplement two times a day, 15 min before the main meal. Control arm participants will receive one capsule of placebo in the same way. The dietary supplement capsule contains the following ingredients: phytosterols, flavonoid-rich extract of bergamot fruit (Citrus bergamia), flavonoid-rich extract of olive fruit (Olea europaea), and vitamin K2. Participants will undergo a medical evaluation and chemical-clinical examinations, which include lipid profile, glycemia, biomarkers of renal, liver and cardiac/muscular functions, interleukins (IL 6, IL-32, IL-37, and IL-38), and innovative mediators of inflammation such as inflamma-miRs (miR-21 and miR-146a), at baseline, and after 6 and 12 weeks of treatment. The decrease in total cholesterol levels and inflammatory biomarkers will be the primary and secondary endpoints of the study.Discussion: This protocol study, planned to verify the effects of BruMeChol™ dietary supplementation in subjects with mild hypercholesterolemia, could also contribute to new study designs for next large-scale multicenter clinical trials.Trial Registration: Australian New Zealand Clinical Trials Registry: ACTRN12619000170123 .

Background: Research published to date on the relationship between insulin resistance (IR) and fructose consumption is scarce, has used different methods, and has yielded sometimes contradictory results. This study aims to determine whether a low-fructose and/or low-sucrose diet supervised by a physician or nurse decreases IR compared to a standard diet.Methods/design: This field trial is located at primary care centers. The participants are adults aged 29 to 66 years, with a Body mass Index (BMI) between 29 and 40.99 kg/m2 and without diabetes. To date, 245 participants have been assigned randomly to the low-fructose diet intervention group (LFDI) at health centers in the western health service zone of Tenerife island, and 245 to the standard-diet control group (SDC) at health centers in the eastern health service zone. Recruitment is opportunistic and is carried out by physicians and nurses at participating health centers. Initially (baseline), and after 24 weeks of intervention, dietary records, physical activity, waist circumference, BMI, blood pressure, fasting blood glucose and insulin concentrations (HOMA2-IR) and lipid profile are recorded; blood glucose and insulin and lipid profile are also recorded 2 h after a 75-g glucose overload. After 48 weeks (24 weeks after the intervention), fasting blood samples are again obtained and a physical examination is performed. All tests and measures are repeated and recorded except dietary records, physical activity and oral glucose overload. Low-fructose diets are designed by calculating free and total (free + fructose associated with sucrose) fructose contents in standard diets, and removing foods with a fructose content in the highest quartile for the amounts in the standard diet. Participants in both groups are prescribed a diet that contains 30 to 40% less than the participant's energy requirements. The primary endpoint is change in HOMA2-IR between baseline and week 24, and other outcomes are change in HDL-cholesterol, LDL-cholesterol, triglycerides , waist circumference to height ratio and BMI. The secondary endpoint is change in HOMA2-IR between week 24 and week 48 together with the outcomes noted above. Comparisons between groups for variables used to indicate IR levels are done with a Student's t test for unpaired variables or the Mann-Whitney U test if the distribution is not normal. Multivariate regression models will be used to control for confounding factors not accounted for in the study design, and for independent prognostic factors.Discussion: If the dietary intervention being tested, i.e., a diet low in fructose/sucrose, is able to reduce IR, the results - if translated into regular clinical practice - could provide a hitherto unavailable tool to prevent type-2 diabetes mellitus.Trial Registration: ISRCTN, ID: ISRCTN41579277 .

Background: Obesity is a public health concern in many countries due to its increasing prevalence. Euiiyin-tang is an herbal medicine formula often used as a clinical treatment for obesity. It acts to eliminate humidity and purify the blood, the causes of obesity identified by the theoretical framework of Korean medicine. The purpose of this study is to evaluate the efficacy and safety of Euiiyin-tang in treating obesity.Methods/design: This study is a randomised, double-blinded and placebo-controlled, multicentre trial. It has two parallel arms: the Euiiyin-tang group and the placebo group. A total of 160 obese adult women will be enrolled in the trial. The participants will be randomly divided at a 1:1 ratio at visit 2 (baseline). The participants will be administered Euiiyin-tang or placebo for 12 weeks. The primary endpoint is the change in weight occurring between baseline and post-treatment. The secondary outcomes include average weight reduction, changes in body fat, waist and hip circumferences, body mass index, and lipid profile, and the results of questionnaires such as the Korean version of Obesity-related Quality of Life, the Korean version of Eating Attitudes Test, the Social Readjustment Rating Scale, and the Stress Reaction Inventory.Discussion: The present study will provide research methodologies for evaluating the efficacy and safety of Euiiyin-tang in patients with obesity. In addition, it will provide evidence of correlation between obesity and Sasang constitutional medicine.Trial Registration: ClinicalTrials.gov, NCT01724099 . Registered on 2 November 2012.

Background: The relationship between dietary components and nonalcoholic fatty liver disease (NAFLD) needs to be further investigated. The potential health benefits of cardamom have been found in some studies. Cardamom showed beneficial effect on hepatomegaly, dyslipidemia, and fasting hyperglycemia in animals. However, some adverse effects of cardamom have been reported in animals. No previous human study had been conducted on the effects of cardamom in NAFLD. This study aims to determine the effects of green cardamom (Elettaria cardamomum) supplementation on blood glucose indices, lipids, inflammatory profiles, and liver function, especially by examining irisin, paraxonase-1 (PON1) and sirtuin-1 (Sirt1) in obese patients with NAFLD.Methods: This trial is to be conducted at the polyclinic of the National Iranian Oil Company (NIOC) Central Hospital, Tehran. Eighty obese patients with NAFLD will be selected according to the eligibility criteria. The NAFLD diagnosis method is ultrasonography. Patients will be randomly divided into two groups by a random-number table (cardamom and placebo groups, two 500-mg capsules, three times/day, taken with meals for 3 months, follow-up monthly). General characteristics, dietary intakes (at the beginning, middle, and end), and physical activity (at the beginning and end) will be assessed using a general, 24-h food recall, and short-form International Physical Activity Questionnaires (IPAQ), respectively. Lifestyle advice will be presented to both groups identically. At the beginning and the end, anthropometrics (weight, height, and waist circumference), blood pressure, extent of fatty liver, and blood biomarkers, including serum glucose indices (fasting blood sugar (FBS)) and insulin (FBI), homeostasis model assessment-insulin resistance (HOMA-IR), Quantitative Insulin Sensitivity Check Index (QUICKI)), lipids (triglyceride (TG), low-density lipoprotein-cholesterol (LDL-c), high-density lipoprotein-cholesterol (HDL-c), total cholesterol (TC)), inflammatory markers (highly sensitive C-reactive protein (hs-CRP), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6)), liver enzymes (alanine transaminase (ALT), aspartate transaminase (AST)), irisin, PON1, and Sirt1, will be determined.Discussion: This trial would be the first to assess the effects of green cardamom on several blood factors, including glucose indices, lipids, inflammatory markers, liver enzymes, irisin, PON1, and Sirt1, and blood pressure and anthropometry in obese patients with NAFLD. Further study of cardamom's potential in improving NAFLD is suggested.Trial Registration: Iranian Registry of Clinical Trials (IRCT), ID number: IRCT2015121317254N4 . Registered on 27 December 2015.

Background: Shifts in the gastrointestinal microbiome have been shown to contribute to the progression of metabolic diseases including prediabetes and type 2 diabetes mellitus. Research suggests that in-vivo modulation of the gut microbiome by specific probiotic microorganisms may improve insulin sensitivity and blood sugar management, preventing or delaying the development of type 2 diabetes mellitus. However, further research is needed to understand the effect of probiotics as a therapy for the treatment of metabolic diseases. An evidence-based multi-species probiotic was developed to encourage a shift in the gastrointestinal bacterial cohort from a disease-prone to a balanced state with the aim of improving metabolic markers associated with type 2 diabetes mellitus.Methods: Sixty adults with a body mass index ≥25 kg/m2 with prediabetes or type 2 diabetes mellitus (diagnosed within the previous 12 months) will be enrolled in a double-blind, placebo-controlled pilot study. Participants will be randomized to a multi-species probiotic or placebo for 12 weeks. Both groups will receive lifestyle and nutritional advice. The primary outcome measure is the change between groups in fasting plasma glucose levels from baseline to 12 weeks. Secondary outcome measures include, but are not limited to, the change in lipid profile, systemic inflammation, gut permeability, and faecal microbial and metabolomic profiles. Blood and stool samples are collected at baseline and 12 weeks after treatment.Discussion: Intentional manipulation of gastrointestinal microbial profiles may be useful for preventing and controlling type 2 diabetes mellitus and its associated metabolic complications.Trial Registration: Australian New Zealand Clinical Trials Registry, ACTRN12613001378718 .

Background: It is becoming increasingly evident that platelet chemokines are involved in distinct aspects of atherosclerosis. The aim of this study was to examine the effects of long-term supplementation with purified anthocyanins on platelet chemokines in hypercholesterolemic individuals and to identify correlations of decreased platelet chemokine levels with serum lipid and inflammatory marker levels. Methods: A total of 146 hypercholesterolemic individuals were recruited and treated with 320 mg of purified anthocyanins (n = 73) or a placebo (n = 73) daily for 24 weeks in this randomized, double-blind, placebo-controlled trial. Results: Anthocyanin supplementation for 24 weeks significantly decreased the plasma CXCL7 (-12.32% vs. 4.22%, P =0 . 001), CXCL5 (-9.95% vs. 1.93%, P = 0.011), CXCL8 (-6.07% vs. 0.66%, P = 0.004), CXCL12 (-8.11% vs. 5.43%, P = 0.023) and CCL2 levels (-11.63% vs. 12.84%, P = 0.001) compared with the placebo. Interestingly, the decreases in the CXCL7 and CCL2 levels were both positively correlated with the decreases in the serum low-density lipoprotein-cholesterol (LDL-C), high-sensitivity C-reactive protein (hsCRP) and interleukin-1β (IL-1β) levels after anthocyanin supplementation for 24 weeks. The decrease in the CXCL8 level was negatively correlated with the increase in the how-density lipoprotein- cholesterol (HDL-C) level and was positively correlated with the decrease in the soluble P-selectin (sP-selectin) level in the anthocyanin group. In addition, a positive correlation was observed between the decreases in the CXCL12 and tumornecrosis factor-α (TNF-α) levels after anthocyanin supplementation. However, the plasma CXCL4L1, CXCL1, macrophage migration inhibitory factor (MIF) and human plasminogen activator inhibitor 1 (PAI-1) levels did not significantly change following anthocyanin supplementation. Conclusions: The present study supports the notion that platelet chemokines are promising targets of anthocyanins in the prevention of atherosclerosis. Trial registration: ChiCTR-TRC-08000240.

Background: Si-Wu-Tang (SWT) is used to treat various gynecological disorders in Chinese medicine. This study investigated the antioxidant and physiological efects of SWT on the skin and liver in healthy adults. Methods: This randomized, crossover, double-blind, placebo-controlled clinical trial was conducted at Chung Shan Medical University Hospital in December 2008. Participants with uncontrolled diabetes, heart disease, liver disease, kidney disease, cancer, and pregnancy were excluded. Sixty healthy volunteers taking no medications were recruited from the community based on the results of their medical history questionnaires and biochemical analyses to confirm their health status. The participants were assigned to two groups: one group drank 125 mL of placebo (n = 30) and the other drank SWT (n = 30) for six continuous days per month for 6 months. The placebo and SWT were then switched between the groups after a 1-month washout period. Anthropometric measurements (body weight, body fat, and body mass index) were performed and fasting blood samples were drawn for various biochemical assays at 1, 3, 6, 10 and 13 months. Abdominal ultrasound and skin examinations were performed at 1, 6 and 13 months. The skin examinations involved assessment of skin roughness, sebum content, hydration, surface water loss, erythema, melanin index, and elasticity on the face (sunlight-exposed sites: middle of ear and nose) and inner arm (sunlight-unexposed sites: center of wrist and elbow joint). Results: Administration of SWT significantly increased the antioxidant index (P = 0.001) and antioxidant enzymes activities (P = 0.001) from baseline to month 6. SWT also suppressed the concentration of serum lipids (triglycerides, P = 0.01; high-density lipoprotein cholesterol, P = 0.23; low-density lipoprotein cholesterol, P = 0.48) and hepatic marker enzymes (glutamic pyruvic transaminase, P = 0.76; glutamic oxaloacetic transaminase, P = 0.65) when com- pared with the placebo group. Abdominal ultrasound in the SWT group revealed a positive impact of SWT on mild fatty liver, gallstones, and mild splenomegaly. Moreover, SWT intake concomitantly elevated erythema (P = 0.011) and markedly lowered skin surface water loss (P = 0.016), sebum content (P = 0.021), and wrinkles (P = 0.024). Conclusions: Oral administration of SWT for 6 months improved the antioxidant level and positively regulated the lipid profile, liver function, and skin integrity and texture. [ABSTRACT FROM AUTHOR]

Background: Hyperlipidemia is a common disease in China. Although 88.9 % of the Chinese population taking lipid-lowering medications has already used a statin, only 61.5 % of the population has reached the goal of low-density lipoprotein cholesterol. Thus, many patients in China seek help from Traditional Chinese Medicine. Yirui capsules are an innovative Chinese Medicine which are designed to improve the blood lipid state in patients with hyperlipidemia. However, there is still a lack of high-quality evidence from clinical trials to support the application. Therefore, we designed a clinical trial to evaluate the safety and efficacy of Yirui capsules for use by patients with hyperlipidemia.Methods/design: This is a multicenter, randomized, double-blinded, placebo-controlled trial. Based on lifestyle modification therapy, eligible patients will randomly be assigned to the Yirui capsule or the placebo group. The primary outcome is the percentage of participants who reach the goal of 30 % low-density lipoprotein cholesterol decline at treatment end-point. The secondary outcomes include the changes from baseline to treatment endpoint in low-density lipoprotein cholesterol, total cholesterol, triglyceride, high-density lipoprotein cholesterol, apolipoprotein A, apolipoprotein B, non-high-density lipoprotein cholesterol, MOS 36-Item Short-Form Health Survey scoring, total and individual item scoring of symptomatic grading and quantifying scale, and body mass index.Discussion: The main ingredients of the Yirui capsule are perilla oil, Folium Ginkgo (Yinxingye), Radix Salviae miltiorrhizae (Danshen), Fructus Crataegi (Shanzha), Rhizoma Alismatis (Zexie), and Radix Notoginseng (Sanqi), which are expected to improve the blood lipid state. This randomized placebo-controlled trial will comprehensively evaluate the effectiveness and safety of Yirui capsules against hyperlipidemia in the hope of providing a new adjunctive Chinese medicine option for clinical practice in dyslipidemia treatment.Trial Registration: ChiCTR-IOR-15006496 .

Background: Previous animal studies suggested that Chlorella, a unicellular green alga, has a preventive role in maintaining serum cholesterol levels against excess dietary cholesterol intake. This study aimed to conduct a pioneering investigation to clarify this issue in healthy subjects by adopting a dietary cholesterol challenge, which has not been used previously in similar studies of Chlorella in hypercholesterolemia.Methods: In this double blind, randomized, placebo-controlled study, 34 participants ingested 510 mg of dietary cholesterol from three eggs concomitantly with a usual dose of Chlorella (5 g/d) or a matched placebo for 4 weeks.Results: The dietary cholesterol challenge induced consistently higher concentrations of serum total cholesterol (TC, P < 0.001), LDL-C (P = 0.004), and HDL-C (P = 0.010) compared with baseline values, suggesting that the challenge was reliable. Thus, we observed a preventive action of Chlorella in maintaining serum TC versus placebo levels (3.5 % versus 9.8 %, respectively; P = 0.037) and LDL-C versus placebo levels (1.7 % versus 14.3 %, respectively; P = 0.012) against excessive dietary cholesterol intake and in augmenting HDL-C versus placebo levels (8.3 % versus 3.8 %, respectively). Furthermore, serum α-carotene showed the best separation between the placebo and Chlorella groups (R(2)X and R(2)Y > 0.5; Q(2) > 0.4).Conclusion: The results suggest that a fully replicated dietary cholesterol challenge may be useful in assessing the effectiveness of dietary supplements in maintaining the serum lipid profiles of adults whose habitual diets are high in cholesterol.Trial Registration: WHO International Clinical Trials Registry Platform ( KCT0000258 ).

Background& Aims: Nutritional supplementation with polyunsaturated fatty acids is important in preterm infants neurodevelopment, but it is not known if the omega-6/omega-3 ratio affects this process. This study was designed to determine the effects of a balanced contribution of arachidonic acid in very preterm newborns fed with formula milk.Methods: This was a randomized trial, in which newborns <1500 g and/or <32 weeks gestational age were assigned to one of two groups, based on the milk formula they would receive during the first year of life. Initially, 60 newborns entered the study, but ultimately, group A was composed of 24 newborns, who were given formula milk with an ω-6/ω-3 ratio of 2/1, and Group B was composed of 21 newborns, given formula milk with an ω-6/ω-3 ratio of 1/1. The infants were followed up for two years: growth, visual-evoked potentials, brainstem auditory-evoked potentials, and plasma fatty acids were periodically measured, and psychomotor development was assessed using the Brunet Lézine scale at 24 months corrected age. A control group, for comparison of Brunet Lézine score, was made up of 25 newborns from the SEN1500 project, who were fed exclusively with breast milk.Results: At 12 months, arachidonic acid values were significantly higher in group A than in group B (6.95 ± 1.55% vs. 4.55 ± 0.78%), as were polyunsaturated fatty acids (41.02 ± 2.09% vs. 38.08 ± 2.32%) achieved a higher average. Group A achieved a higher average Brunet Lézine score at 24 months than group B (99.9 ± 9 vs. 90.8 ± 11, p =0.028). The Brunet Lézine results from group A were compared with the control group results, with very similar scores registered between the two groups (99.9 ± 9 vs. 100.5 ± 7). There were no significant differences in growth or evoked potentials between the two formula groups.Conclusions: Very preterm infants who received formula with an ω-6/ω-3 ratio of 2/1 had higher blood levels of essential fatty acids during the first year of life, and better psychomotor development, compared with very preterm newborns who consumed formula with an ω-6/ω-3 of 1/1. Therefore, formula milk with an arachidonic acid quantity double that of docosahexaenoic acid should be considered for feeding very preterm infants.Trial Registration: ClinicalTrials.gov Identifier NCT02503020.

Background: Overweight subjects easily develop alterations of the glucose and lipid metabolism and are exposed to an increased cardiometabolic risk. This condition is potentially reversible through the improvement of dietary and behavioural habits. However, a well-assembled nutraceutical would be a useful tool to better improve the metabolic parameters associated to overweight and insulin resistance.Methods: To evaluate the effect of a combined nutraceutical containing berberine, chlorogenic acid and tocotrienols, we performed a double blind, cross-over designed trial versus placebo, in 40 overweight subjects with mixed hyperlipidaemia. After the first 8 weeks of treatment (or placebo), patients were asked to observe a 2-week washout period, and they were then assigned to the alternative treatment for a further period of 8 weeks. Clinical and laboratory data associated to hyperlipidaemia and insulin resistance have been obtained at the baseline, at the end of the first treatment period, after the washout, and again after the second treatment period.Results: Both groups experienced a significant improvement of anthropometric and biochemical parameters versus baseline. However, total cholesterol, LDL cholesterol, triglycerides, non-HDL cholesterol, fasting insulin, HOMA-IR, GOT and Lipid Accumulation Product decreased more significantly in the nutraceutical group versus placebo.Conclusions: This combination seems to improve a large number of metabolic and liver parameters on the short-term in overweight subjects. Further studies are needed to confirm these observations on the middle- and long-term. [ABSTRACT FROM AUTHOR]

The article offers information on a study which focuses on the role of dietary fibers in cardiovascular disease and body weight management. It states that flaxseeds are a good source of dietary fibers and contains a large proportion of water-soluble viscous fibers in it. It examines effect of flaxseed dietary fibers on blood lipids and fecal excretion of fat and energy. It concludes that flax drink and flax bread results in decreased plasma total and LDL-cholesterol and increased fat excretion.

The article focuses on a study which determines that Visceral obesity and insulin resistance are associated with postprandial accumulation of atherogenic chylomicron remnants.

Background: The aim in this study was to investigate the effect of vitamin D (25(OH)D3) supplementation on heat shock protein 60 (HSP 60) and other inflammatory markers (IL-17, TNF-α, PAB) in patients with coronary heart disease (CHD). Methods: In this double-blind, randomized clinical trial, we recruited 80 male and female patients aged 30–60 with CHD and 25(OH)D3 serum levels < 30 ng/ml from Rasool-e-Akram Hospital in Tehran, Iran. Serum levels of HSP 60 as primary outcome, and 25(OH)D3, IL-17, TNF-α, PAB, lipid profiles and parathyroid hormone (PTH) as secondary outcomes were measured at baseline and post-intervention. We randomly assigned eligible participants to a placebo group ( N = 40) or an intervention group (N = 40) (50,000 IU/wk. vitamin D supplement) for eight weeks. Results: The results demonstrated that vitamin D supplementation resulted in a significant increase in 25(OH) D3 serum levels in the intervention group compared to the placebo group (46.86 vs. 7.28 ng/ml). PTH levels decreased in the intervention group compared to the placebo group (− 19.81 vs. 2.92 pg/ml) after eight weeks of supplementation. Furthermore, we observed a significant change in waist circumference (− 0.97 vs. -0.26 cm), fat percentage (−.13 vs. 0.1%), systolic blood pressure (− 3.85 vs. -2.11 mmHg) and diastolic blood presure (− 4 vs. -1.86 mmHg) in the vitamin D group compared to the placebo group (all P values < 0.05). Other variables did not significantly change after the intervention. Conclusion: Based on our findings, weekly vitamin D supplementation of 50,000 IU for eight weeks in patients with CHD resulted in decreased systolic and diastolic blood pressure, waist circumference and fat percentage. No significant effect on HSP 60, inflammatory markers or lipid profiles was observed. Trial registration: IRCT, IRCT201612122365N14. Registered 12 December 2016. [ABSTRACT FROM AUTHOR]

Background: Heart failure (HF) is associated with decreased quality of life, high re-admission rate and poor prognosis. In particular, ischemic heart failure (IHF) has a worse prognosis than nonischemic HF. The use of traditional Chinese medicine (TCM) alongside Western medicine to treat HF has developed into an integrative treatment model in China. There have been small clinical trials and experimental studies to demonstrate the efficacy of TCM for treating HF; however, there is still a lack of high-quality trials. Qishen Yiqi dripping pills (QSYQ), a TCM drug, have been commonly used alongside standardized Western medicine to treat IHF. This paper describes the protocol for the clinical assessment of QSYQ in IHF patients.Method: A randomized, double-blind, multicenter, placebo-controlled trial will assess the efficacy and safety of QSYQ in the treatment of IHF. The trial is to enroll 640 IHF patients from 32 hospitals in China. Besides their standardized Western medicine, patients will be randomized to receive treatment of either QSYQ or placebo for 6 months and follow-up monitoring for at least a further 6 months. The primary outcome is increased exercise capacity of patients, which will be measured using the 6-minute walking test (6MWT). The secondary outcomes include composite endpoints: all-cause mortality, frequency of hospitalization or emergency due to cardiovascular events, brain natriuretic peptide levels, left ventricular ejection fraction, and cardiothoracic ratio will be documented, as well as scores on the New York Heart Association classification and Minnesota quality of life index, and information obtained from the four TCM diagnostic methods. Blood lipid tests will also be administered.Discussion: The integrative treatment model of TCM alongside Western medicine has developed into a treatment model in China. The rigorous design of the trial will assure an objective and scientific assessment of the efficacy and safety of QSYQ in the treatment of IHF. [ABSTRACT FROM AUTHOR]
