ABSTRACT

BACKGROUND: With the increasing watching of programs such as Mukbang, the study of eating behaviors and anthropometric parameters and their relationship with Mukbang should be considered to prevent chronic diseases and eating disorders. This study investigated the relationship between watching Mukbang with eating behaviors and anthropometric parameters in female students at Islamic Azad University, Science and Research Branch, Tehran, Iran. STUDY DESIGN: A cross-sectional study. METHODS: In this study, 114 female students aged 18 to 31 years were selected using simple random sampling. General information, watching Mukbang status, and the Dutch Eating Behavior Questionnaire (DEBQ) were administered to the participants online. RESULTS: The prevalence of Mukbang watching in female students of the present study was 60.5%. Furthermore, there was no significant relationship between the frequency of Mukbang watching and emotional or restrained eating behavior (P > 0.05), while there was a significant relationship between external eating behavior and the frequency of watching Mukbang (P=0.0001). It was found that with increasing watching time, external eating also increased. According to the results of logistic regression analysis, the external eating chance was 27% lower in students who watch Mukbang rarely than those who have never watched such a show. However, this chance was 0.31 and 9.58 times higher in students who occasionally and always watch Mukbang, respectively. CONCLUSION: There is a significant relationship between external eating behaviors and watching Mukbang.

ABSTRACT

Background: The COVID-19 pandemic is considered a major health problem all over the world which has caused extensive and worldwide mortality and morbidities along with vast economic and political impact. Limitations of our knowledge and controversies in treatment modalities make the control and management of this disease more difficult. The status of electrolytes especially Mg and Zn in plasma and its correlation with the clinical situation and criteria for recovery has been investigated in various studies. Limited data in Iran mandate the design of a trial for evaluating our critically ill patients. We designed this study to investigate the correlation between plasma levels of Mg and Zn and the outcome including patients' need for assisted/controlled ventilation, time required for weaning, length of ICU stay, and probable cause of death. Materials and Methods: 413 patients with severe respiratory signs of COVID-19 disease who were admitted to the ICUs of 3 medical centers of Shahid Beheshti University of Medical Sciences were evaluated for plasma levels of Mg and Zn. Supplemental therapy was introduced when needed and was followed until discharge from ICU or death. All recorded data were analyzed by statistical methods and results were compared with similar studies. Results: 20.6% and 35.1% of all participants had low serum levels of Mg and Zn, respectively. 11 patients (2.7%) died through the treatment period. 56.9% and 61.0% of participants received Mg and Zn supplements, respectively. Conclusion: According to our results, serum Mg and Zn levels did not show a significant correlation with the risk of death due to severe COVID-19 disease, prolonged assisted ventilation, or duration of ICU stay. There was no significant association between Mg and Zn supplementation with the risk of death due to severe COVID-19; however, it showed an inverse relationship with the time required for assisted ventilation and the duration of ICU stay. It seems that Mg and Zn supplementation can be useful in preventing or managing some of the morbidities among COVID-19 patients.

ABSTRACT

BACKGROUND: The link between dietary protein intake and the risk of kidney dysfunction is always a challenging issue. This study aimed to investigate the relationship between total protein, plant protein, and animal protein intake with the risk of incident chronic kidney disease (CKD). METHODS: This study was performed on 1639 adults aged ≥27 years who participated in the Tehran Lipid and Glucose Study. Dietary data were evaluated using a valid and reliable semi-quantitative food frequency questionnaire (FFQ). Total protein content, plant protein, and animal protein of each participant were calculated. Glomerular filtration rate (GFR) less than 60 mL / min / 1.73 m2 has been considered as the definition of CKD. Odds Ratio (OR) was calculated using logistic regression to show the association between the risk of incident CKD and dietary exposures. RESULTS: After adjusting for age, sex, body mass index, smoking, total energy intake, total fiber intake, dietary fat, physical activity, diabetes, and hypertension, there was no significant association of total protein and animal protein consumptions with the incidence of CKD. After adjustment for confounders, compared with the lowest tertile of plant protein consumption, OR of incident CKD in the highest tertile was 0.29 (95% confidence interval [95% CI] 0.15 to 0.55) with a significant trend (P for trend < 0.001). CONCLUSION: The results of this study confirmed an inverse association between plant protein intake and the risk of incident CKD, which demonstrates the protective role of plant-based protein in a diet on kidney function.

ABSTRACT

Type 2 diabetes mellitus (T2DM) is a serious public health problem accompanies with several complications. This study was conducted to evaluate the effects of chromium picolinate (CrPic) supplementation on the glycemic status and lipid profile in patients with T2DM. The patients with T2DM (n = 52) were randomly allocated into 2 groups. One group received 400 µg CrPic per day and the other group took placebo; the intervention duration was 8 weeks. Anthropometric indices and metabolic factors were measured at the beginning, and at end of the study. The patients were recommended not to change their normal diet, life style and medication. No significant changes were observed for weight, body mass index, and fasting blood glucose (FBG) in both groups; while intra-groups changes in homeostatic model assessment for insulin resistance (HOMA-IR) value was significant (p < 0.05). Results of analysis of covariance showed that there were significance differences between groups in total cholesterol, low density lipoprotein cholesterol and HOMA-IR at the end of the intervention adjusting for baseline levels (p = 0.035, 0.030 and < 0.001, respectively). In this study, oral supplementation with 400 µg CrPic for eight weeks did not alter FBG concentration as well as anthropometric parameters in individuals with T2DM. However, the modest beneficial effects of chromium supplementation on insulin resistance as indicated by HOMA-IR and lipid profile were found.

ABSTRACT

Introduction: The effect of using high dose pomegranate extract on sepsis and its safety is not clarified. Considering the fact that proper immune and inflammatory responses are needed to cope with infection, the aim of current study was to assess the effect of high dose pomegranate extract consumption on oxidative and inflammatory responses after disease induction in rat model of sepsis. METHODS: Sepsis was induced by Cecal Ligation and Perforation (CLP) surgery. Adult male Wistar rats were divided into three groups of eight animals: Sham; CLP and POMx [consumed POMx (250 mg of pomegranate fruit extract/kg/day) for four weeks before CLP]. RESULTS: Peritoneal neutrophil myeloperoxidase activity was significantly lower in POMx compared with Sham and CLP groups (p < 0.01 and p < 0.05, respectively). Although antioxidant enzymes were higher in POMx group after sepsis induction, lower serum total antioxidant status (TAS) (p < 0.01 compared with both CLP and Sham groups) and higher liver thiobarbituric acid reactive species (TBARS) levels were observed in this group (p < 0.01 and p < 0.05, compared with Sham and CLP groups, respectively). CONCLUSION: High dose POMx consumption prior to sepsis induction, suppressed the vital function of neutrophils in early hours after sepsis initiation, resulting in higher oxidative stress. These findings indicate that caution should be made in using high dose pomegranate products. The main message of current study is that such useful compounds as antioxidants including pomegranate juice which have beneficial effects on general health status may have detrimental effects if misused or used in high doses.

ABSTRACT

Diabetes mellitus is the most common metabolic disorder worldwide. This study examined the effect of turmeric supplementation on glycemic status, lipid profile, hs-CRP and total antioxidant capacity in hyperlipidemic type 2 diabetic patients. In this double-blind, randomized clinical trial, 80 hyperlipidemic type 2 diabetic patients were divided into turmeric (2,100 mg powdered rhizome of turmeric daily) and placebo groups for 8 weeks. Body weight, fasting plasma glucose, hemoglobin A1c (HbA1c), serum insulin, triglyceride (TG), total cholesterol, low density lypoprotein cholesterol (LDL-c), high density lypoprotein cholesterol, apolipoprotein A1, apolipoprotein B, high sensitivity C-reactive protein (hs-CRP), and total antioxidant capacity were measured before and after intervention. Statistical analysis was carried out using paired and independent t and chi-square tests. Seventy five patients completed the study. The turmeric group showed significant decreases in body weight, TG, and LDL-c compared with baseline (p value < 0.05). Body mass index, TG, and total cholesterol decreased significantly in the turmeric group compared with the placebo group (p value < 0.05). No significant changes were observed in other parameters between the two groups after intervention (p value < 0.05). Turmeric improved some fractions of lipid profile and decreased body weight in hyperlipidemic patients with type 2 diabetes. It had no significant effect on glycemic status, hs-CRP, and total antioxidant capacity in these patients.

ABSTRACT

OBJECTIVE: Previous studies have shown that the bioflavonoid quercetin has anti-inflammatory and anti-nociceptive effects. We investigated the effect of quercetin supplementation on inflammation, disease severity, and clinical symptoms in women with rheumatoid arthritis (RA). METHODS: The present study was a randomized, double-blind, placebo-controlled clinical trial in which 50 women with RA were allocated into a quercetin (500 mg/day) or placebo group for 8 weeks. Plasma levels of high-sensitivity tumor necrosis factor-α (hs-TNFα), erythrocyte sedimentation rate (ESR), clinical symptoms including early morning stiffness (EMS), morning and after-activity pain, and tender (TSC) and swollen joint counts (SJC) were determined. Disease activity and functional disability were assessed by Disease Activity Score 28 (DAS-28), physician global assessment (PGA), and a health assessment questionnaire (HAQ) at the beginning and end of the study. RESULTS: Quercetin supplementation for 8 weeks significantly reduced EMS, morning pain, and after-activity pain (p < 0.05). DAS-28 and HAQ scores decreased in the quercetin group compared to placebo and the number of patients with active disease significantly decreased in the quercetin group. Plasma hs-TNFα level was significantly reduced in the quercetin group compared to placebo (p < 0.05). There were no significant differences in TJC and SJC between groups but TJC significantly decreased in the quercetin group after the intervention. Supplementation had an effect on ESR but it was not significant (p > 0.05). CONCLUSIONS: Five hundred milligrams per day quercetin supplementation for 8 weeks resulted in significant improvements in clinical symptoms, disease activity, hs-TNFα, and HAQ in women with RA.

ABSTRACT

BACKGROUND: Acceleration in sputum smear conversion helps faster improvement and decreased probability of the transfer of TB. In this study, we aimed to investigate the effect of green tea extract supplementation on sputum smear conversion and weight changes in smear positive pulmonary TB patients in Iran. METHODS: In this double blind clinical study, TB patients were divided into intervention, (n=43) receiving 500 mg green tea extract (GTE), and control groups (n=40) receiving placebo for two months, using balanced randomization. Random allocation and allocation concealment were observed. Height and weight were measured at the beginning, and two and six months post-treatment. Evaluations were performed on three slides, using the ZiehlNeelsen method. Independent and paired t test, McNemar's, Wilcoxon, Kaplan-Meier, Cox regression model and Log-Rank test were utilized. Statistical significance was set at p<0.05. This trial was registered under IRCT201212232602N11. RESULTS: The interventional changes and the interactive effect of intervention on weight were not significant (p>0.05). In terms of shortening the duration of conversion, the case to control proportion showed a significant difference (p=0.032). Based on the Cox regression model, the hazard ratio of the relative risk of delay in sputum smear conversion was 3.7 (p=0.002) in the higher microbial load group compared to the placebo group and 0.54 (95% CI: 0.31-0.94) in the intervention compared to the placebo group. CONCLUSION: GTE decreases the risk of delay in sputum smear conversion, but has no effect on weight gain. Moreover, it may be used as an adjuvant therapy for faster rehabilitation for pulmonary TB patients.

ABSTRACT

OBJECTIVE: The aim of this study was to determine effects of probiotic yogurt and multispecies probiotic capsule supplementation on mental health and hypothalamic-pituitary-adrenal axis in petrochemical workers. METHODS: The present randomized double-blind, placebo-controlled trial was conducted on 70 petrochemical workers. Subjects were randomly divided into three groups to receive 100 g/day probiotic yogurt + one placebo capsule (n = 25) or one probiotic capsule daily + 100 g/day conventional yogurt (n = 25) or 100 g/day conventional yogurt + one placebo capsule (n = 20) for 6 weeks. Mental health parameters including general health questionnaire (GHQ) and depression anxiety and stress scale (DASS) scores were measured. Fasting blood samples were obtained at the beginning and 6 weeks after the intervention to quantify hypothalamic-pituitary-adrenal axis. RESULTS: After 6 weeks of intervention, a significant improvement of GHQ was observed in the probiotic yogurt (18.0 ± 1.5 vs. 13.5 ± 1.9, P = 0.007) and in the probiotic capsule group (16.9 ± 1.8 vs. 9.8 ± 1.9, P = 0.001), as well as a significant improvement in DASS scores in the probiotic yogurt (23.3 ± 3.7 vs. 13.0 ± 3.7, P = 0.02) and the probiotic capsule group (18.9 ± 3.2 vs. 9.4 ± 4.0, P = 0.006). However, there was no significant improvement in the conventional yogurt group (P = 0.05 for GHQ and P = 0.08 for DASS). DISCUSSION: The consumption of probiotic yogurt or a multispecies probiotic capsule had beneficial effects on mental health parameters in petrochemical workers.

ABSTRACT

BACKGROUND: The aim of the current study was to determine effects of probiotic yoghurt and multispecies probiotic capsule supplementation on biomarkers of oxidative stress and inflammatory factors in petrochemical workers. METHODS: This randomized, double-blind, placebo-controlled trial was done among petrochemical workers. Subjects were randomly divided into three groups to receive 100 g/day probiotic yogurt (n = 12) or one probiotic capsule daily (n = 13) or 100 g/day conventional yogurt (n = 10) for 6 weeks. The probiotic yoghurt was containing two strains of Lactobacillus acidophilus and Bifidobacterium lactis with a total of min 1 × 10(7) CFU. Multispecies probiotic capsule contains seven probiotic bacteria spices Actobacillus casei 3 × 10(3), L. acidophilus 3 × 10(7), Lactobacillus rhamnosus 7 × 10(9), Lactobacillus bulgaricus 5 × 10(8), Bifidobacterium breve 2 × 10(10), Bifidobacterium longum 1 × 10(9) and Streptococcus thermophilus 3 × 10(8) CFU/g. Fasting blood samples were obtained at the beginning and end of the trial to quantify biomarkers of oxidative stress and inflammatory factors. RESULTS: Although a significant within-group decrease in plasma protein carbonyl levels was seen in the probiotic capsule group (326.0 ± 308.9 vs. 251.0 ± 176.3 ng/mL, P = 0.02), the changes were similar among the three groups. In addition, significant within-group decreases in plasma iso prostaglandin were observed in the probiotic supplements group (111.9 ± 85.4 vs. 88.0 ± 71.0 pg/mL, P = 0.003) and in the probiotic yogurt group (116.3 ± 93.0 vs. 92.0 ± 66.0 pg/mL, P = 0.02), nevertheless there were no significant change among the three groups. CONCLUSIONS: Taken together, consumption of probiotic yogurt or multispecies probiotic capsule had beneficial effects on biomarkers of oxidative stress in petrochemical workers.

ABSTRACT

BACKGROUND: The aim was to examine the effects of high-cocoa polyphenol-rich chocolate on lipid profiles, weight, blood pressure, glycemic control, and inflammation in individuals with Type 2 diabetes and hypertension. METHODS: Sixty individuals [32 in dark chocolate group (DCG) and 28 in white chocolate group (WCG)] with Type 2 diabetes on stable medication were enrolled in a randomized, placebo-controlled double-blind study. Subjects were randomized to consume 25 g DCG or WCG for 8 weeks. Changes in weight, blood pressure, glycemic control, lipid profile, and high sensitive C-reactive protein (hsCRP) were measured at the beginning and end of the intervention. This clinical trial was registered at the Iranian registry of clinical trials. RESULTS: In DCC group, compared with baseline, serum levels of Apo A-1 (P = 0.045) was increased and fasting blood sugar (FBS) (P = 0.027), hemoglobin A1c (HbA1c) (P = 0.025), Apo B (P = 0.012) and Log of hsCRP (P = 0.043) levels were decreased at the end of study. No changes were seen within the WCG in studied parameters. High polyphenol chocolate consumption compared to white chocolate resulted in significant decrease in of systolic (-5.93 ± 6.25 vs. -1.07 ± 7.97 mmHg, P = 0.004) and diastolic blood pressure (-6.4 ± 6.25 vs. 0.17 ± 7.9 mmHg, P = 0.002), FBS (-7.84 ± 19.15 vs. 4.00 ± 20.58 mg/dl, P = 0.019) over the course of 8 weeks of daily chocolate consumption neither weight nor body mass index and TG levels altered from baseline. CONCLUSION: High polyphenol chocolate is effective in improving TG levels in hypertensive patients with diabetes and decreasing blood pressure and FBS without affecting weight, inflammatory markers, insulin resistance or glycemic control.

ABSTRACT

OBJECTIVES: Multiple sclerosis (MS) is an immune-mediated neurodegenerative disease of central nervous system and recent studies show that inflammatory processes are highly associated with neurodegeneration in the brain. The purpose of this study was to investigate the effect of coenzyme Q10 supplementation on inflammatory and anti-inflammatory markers in patients with MS. METHODS: This randomized, double-blind, placebo-controlled clinical study was performed among 48 patients with relapsing-remitting MS. Subjects were randomly assigned to a placebo group (n = 24) or coenzyme Q10 (CoQ10)-supplemented group (500 mg/day, n = 24). The intervention was administered for 12 weeks. Peripheral blood samples were collected at baseline and after 12-week intervention, to measure inflammatory (tumor necrosis factor-α (TNF-α), interleukin (IL)-6, and matrix metalloproteinase (MMP)-9) and anti-inflammatory (IL-4 and TGF-ß) markers. RESULTS: Forty-five patients completed the study. After 12 weeks of intervention, the TNF-α levels (P = 0.003) decreased significantly in the CoQ10 group. Subjects in the CoQ10 group had significantly lower IL-6 levels (P = 0.037), compared to the placebo group. CoQ10 supplementation also resulted in decreased serum levels of MMP-9 as compared to the placebo group (P = 0.011). However, CoQ10 supplementation did not alter the IL-4 and TGF-ß levels (P = 0.16 and P = 0.81, respectively). DISCUSSION: CoQ10 supplementation at a dosage of 500 mg appears to decrease the inflammatory markers (TNF-α, IL-6, and MMP-9) in patients with MS.

ABSTRACT

BACKGROUND: Tocotrienols (T3) were neglected in the past; today, get attentions due to their antioxidant and none-antioxidant activity. The objective of this study was to evaluate the effects of the daily intake of 200 mg T3 added in canola oil over 8 weeks on microalbuminuria, inflammation, and nitrosative stress in type 2 diabetic patients. METHODS: This study was a double-blinded, placebo-controlled, randomized trial. A total of 50 patients with T2DM and FBS >126 mg/dl treated by non-insulin hypoglycemic drugs were randomly assigned to receive either 15 ml T3-enriched canola oil (200 mg/day T3) or pure canola oil for 8 weeks. Urine microalbumin, volume and creatinine levels, serum hs-CRP, and nitric oxide (NO) levels were measured before and after intervention. RESULTS: From 50 patients participated in this study, 44 completed the study. There were no significant differences in baseline characteristics, dietary intake, and physical activity between groups. Urine microalbumin and serum hs-CRP were declined significantly in T3-treated group. At the end of the study, patients who treated with T3 had lower urine microalbumin (11 (9, 25) vs. 22 (15, 39.75) nmol/dl, P = 0.003) and hs-CRP changes (-10.91 ± 15.5 vs. -9.88 ± 27.5 Pg/ml, P = 0.048) than control group. A non-significant decrease was also observed in serum NO level in T3-treated group with no changes in urine volume and creatinine levels. CONCLUSIONS: These findings indicate that T3 leads to ameliorate proteinuria and can protect the kidney against inflammation (hs-CRP) and nitrosative stress (NO).

ABSTRACT

BACKGROUND: Considering the increased production of free radicals and inflammatory factors in rheumatoid arthritis (RA) and the effects of bioflavonoid quercetin on reducing oxidative stress, inflammation and blood pressure, the present study examined the effects of bioflavonoid quercetin on total antioxidant capacity (TAC) of plasma, lipid peroxidation and blood pressure in women with RA. METHODS: The current study was a randomized double-blind clinical trial in which 51 women with RA aged 19-70 years, were participated. Patients were assigned into quercetin (500 mg/day) or placebo groups for 8 weeks. Dietary intake was recorded using 24-h dietary recall questionnaire and the physical activity was assessed through an international short questionnaire of physical activity at the beginning and end of the study. Plasma TAC and malondialdehyde (MDA) using colorimetric method, oxidized low density lipoprotein (ox-LDL) and high sensitivity C-reactive protein (hs-CRP) using enzyme-linked immunosorbent assay method and also blood pressure were measured at the beginning and end of intervention. RESULTS: After 8 weeks there were no significant differences in TAC of plasma, ox-LDL, MDA, hs-CRP, systolic and diastolic blood pressure between quercetin and placebo groups and in each group comparing before and after. CONCLUSIONS: In this study, quercetin had no effect on oxidative and inflammatory status of plasma and blood pressure in patients with RA. Further studies are needed to ensure the effect of quercetin on oxidative stress and inflammation in human.

ABSTRACT

BACKGROUND: A limited amount of data exists regarding the effect of lipoic acid (LA), an oral antioxidant supplement, on cytokine profiles among multiple sclerosis (MS) patients. OBJECTIVE: We aimed to assess the effect of daily consumption of LA on the cytokine profiles in MS patients. METHODS: In this double-blind, placebo-controlled, randomized clinical trial, 52 relapsing-remitting MS patients with an age range of 18-50 years were recruited into 2 groups: LA consumption (1,200 mg/day) or placebo. Patients followed their prescribed supplements for 12 weeks. Fasting blood samples for cytokine profile measurement were collected at baseline and after the intervention. Anthropometric parameters were measured based on the standard guidelines. RESULTS: INF-γ, ICAM-1, TGF-ß and IL-4 were significantly reduced in the LA group compared to the placebo group [(INF-γ: 0.82 ± 0.2 vs. 0.2 ± 0.2 pg/ml, p < 0.0001), (ICAM-1: 20.2 ± 9.4 vs. 8 ± 10 ng/ml, p = 0.0001), (TGF-ß: 103.1 ± 20.2 vs. 54.9 ± 26 ng/ml, p < 0.0001) and (IL-4: 0.1 ± 0.1 vs. 1.02 ± 1.7 ng/ml, p = 0.0112)]. No significant changes in TNF-α, IL-6, EDSS and MMP-9 were found between the LA and placebo groups (p = 0.6, p = 0.8, p = 0.09 and p = 0.8, respectively). CONCLUSION: The results suggested that consumption of 1,200 mg LA per day beneficially affects several inflammatory cytokines including INF-γ, ICAM-1 TGF-ß and IL-4. Further investigations are needed to verify the beneficial role of LA on other cytokine profiles among MS patients.

ABSTRACT

BACKGROUND: Sepsis is one of the major causes of death in intensive care units. Oxidative stress and hyper-inflammation has been shown to be major cause of mortality and morbidity in septic cases. Pomegranate is a fruit considered for its antioxidant and anti-inflammatory properties. The aim of this study is to evaluate the effect of a standard pomegranate fruit liquid extract (POMx), on mortality and peritoneal bacterial load in cecal ligation and perforation (CLP) sepsis model. METHODS: Male wistar rats were divided into four groups of 24 each: sham; CLP; prevention (consumed POMx [250 mg of polyphenols/kg/day] for 4 weeks before CLP); treatment (received a single drink of POMx [250 mg of polyphenols/kg] after CLP). Each group was divided into three subgroups, each containing eight animals, for bacterial load and survival (with and without antibiotics) studies. Sepsis was induced by CLP surgery. Ten day survival rate was recorded. Peritoneal bacterial load was also assessed. Data were analyzed using Log-rank and Kruskal-Wallis tests. RESULTS: There was no significant difference in survival rate of CLP, prevention and treatment groups, in subgroups without antibiotics. However, in subgroups with antibiotics, the prevention group had significantly lower survival rate than sham group (P < 0.05). Conversely, the bacterial load of prevention and treatment groups were significantly higher than sham group (P < 0.01). CONCLUSIONS: Our study demonstrates for the first time that pomegranate extract could increase mortality rate via increasing peritoneal cavity bacterial load, in CLP sepsis model. More studies to assess mechanisms of this effect are warranted.

ABSTRACT

BACKGROUND: Low grade inflammation and oxidative stress are the key factors in the pathogenesis and development of diabetes and its complications. Coenzyme Q10 (CoQ10) is known as an antioxidant and has a vital role in generation of cellular energy providing. This study was undertaken to evaluate the effects of CoQ10 supplementation on lipid profiles and glycemic controls in patients with diabetes. METHODS: Fifty patients with diabetes were randomly allocated into two groups to receive either 150 mg CoQ10 or placebo daily for 12 weeks. Before and after supplementation, fasting venous blood samples were collected and lipid profiles containing triglyceride, total cholesterol, low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) and glycemic indices comprising of fasting plasma glucose (FPG), insulin and hemoglobin A1C (HbA1C) were measured. Insulin resistance was calculated using HOMA-IR index. RESULTS: Forty patients completed the study. After intervention FPG and HbA1C were significantly lower in the CoQ10 group compared to the placebo group, but there were no significant differences in serum insulin and HOMA-IR between the two groups. Although total cholesterol did not change in the Q10 group after supplementation, triglyceride and HDL-C significantly decreased and LDL-C significantly increased in the CoQ10 group. CONCLUSION: The present study showed that treatment with Q10 may improve glycemic control with no favorable effects on lipid profiles in type 2 patients with diabetes.

ABSTRACT

OBJECTIVES: Multiple sclerosis is a neurodegenerative and demyelinating disease of central nervous system. High levels of oxidative stress are associated with inflammation and play an important role in pathogenesis of multiple sclerosis. This double-blind, randomized controlled clinical study was carried out to determine the effect of daily consumption of lipoic acid on oxidative stress among multiple sclerosis patients. METHODS: A total of 52 relapsing-remitting multiple sclerosis patients, aged 18-50 years with Expanded Disability Status Scale ≤5.5 were assigned to consume either lipoic acid (1200 mg/day) or placebo capsules for 12 weeks. Fasting blood samples were collected before the first dose taken and 12 hours after the last. Dietary intakes were obtained by using 3-day dietary records. RESULTS: Consumption of lipoic acid resulted in a significant improvement of total antioxidant capacity (TAC) in comparison to the placebo group (P = 0.004). Although a significant change of TAC (-1511 mmol/L, P = 0.001) was found within lipoic acid group, other markers of oxidative stress including superoxide dismutase activity, glutathione peroxidase activity, and malondialdehyde levels were not affected by lipoic acid consumption. DISCUSSION: These results suggest that 1200 mg of lipoic acid improves serum TAC among multiple sclerosis patients but does not affect other markers of oxidative stress.

ABSTRACT

BACKGROUND: Previous studies have demonstrated that nuts consumption have beneficial effects on serum lipid profiles in hyperlipidemic or normolipidemic subjects. However, similar studies in diabetes field are quite rare. So, we aimed to investigate the effects of hazelnut consumption on fasting blood sugar (FBS) and lipid profiles in patients with type 2 Diabetes. MATERIALS AND METHODS: An 8-week controlled randomized parallel study in patients with type 2 diabetes. Fifty eligible volunteers were assigned to either the control or intervention groups. 10% of total daily calorie intake was replaced with hazelnuts in intervention group. Blood samples were collected from fasting patients at the start and at the end of the study. RESULTS: After 8 weeks, there were significant differences in high-density lipoprotein-cholesterol (HDL-C) concentrations between two groups, using analyses of covariance (P = 0.009), which was due to the larger HDL-C reduction in control group (P = 0.003). Although, Hazelnut group achieved greater reduction in triglyceride (TG) concentrations than control group, these changes were not statistically significant. Neither between-group changes nor within-group changes were significant for FBS, total cholesterol (TC), TG, and low-density lipoprotein-cholesterol (LDL-C) levels. CONCLUSION: Results of this study indicated that incorporation of hazelnuts into diet can prevent reduction of HDL-C concentrations in patients with type 2 diabetes, but had no effect on FBS or other lipid profile indices.

ABSTRACT

BACKGROUND: N-3 Fatty acids reduce the risk of cardiovascular disease. Previous studies have shown that they may reduce inflammation, oxidative stress, and fat mass in patients with type 2 diabetes, but the results are inconclusive, due, in part, to type of omega-3 fatty acids used. The aim of this study was to determine the effects of pure eicosapentaenoic (EPA) and docosahexaenoic acids (DHA), the two major omega-3 fatty acids, on inflammation, oxidative stress, and fat mass in patients with type 2 diabetes. METHODS: Sixty patients with DM-II were randomly allocated to receive daily either ~1 gr EPA or ~1 gr DHA, or a canola oil as placebo for 12 weeks in a randomized triple-blind, placebo-controlled trial. Serum MDA, CRP, body weight, BMI, and fat mass were measured at baseline and after intervention. RESULTS: Forty-five patients with a mean (±SD) age of 54.9 ± 8.2 years with BMI of 27.6 ± 4.1 kg/m(2) and fasting blood glucose 96.0 ± 16.2 mg/dl completed the intervention. Neither EPA nor DHA had significant effects on serum FBS, C-reactive protein, body weight, BMI, and fat mass after intervention (P > 0.05). In addition, while MDA increased 18% in the placebo group (P = 0.009), it did not change in the EPA or DHA group (P > 0.05). CONCLUSIONS: Twelve weeks of supplementation with 1gr/d EPA or DHA prevent increasing oxidative stress without changing marker of inflammation. This study is the first report demonstrating that neither EPA nor DHA have effects on body fat mass in type 2 diabetic patients.
