There is scarce data on the effects of omega-3 fatty acids and vitamin E co-supplementation on metabolic status in patients with fibrocystic breast disease (FBD). The current study was carried out to determine the effects of omega-3 fatty acids and vitamin E co-supplementation on metabolic status in patients with FBD.A randomized clinical trial was conducted on 56 patients with FBD. Participants were randomly divided into two groups to receive either 1000 mg omega-3 fatty acids plus 400 mg vitamin E (n = 28) or placebo (n = 28) for 12 weeks. Fasting blood samples were taken at the beginning of the study and after 12 weeks of intervention to determine inflammatory factors, biomarkers of oxidative stress, and metabolic profiles.After 12 weeks of intervention, changes in serum high-sensitivity C-reactive protein (-2171.4 ± 3189.1 vs. +696.9 ± 2774.8 ng/mL, P = 0.001) and plasma nitric oxide (+1.8 ± 4.0 vs. -0.1 ± 2.4 µmol/L, P = 0.04) in supplemented women were significantly different from those in the placebo group. In addition, compared to the placebo group, subjects who consumed omega-3 fatty acids plus vitamin E supplements had significantly decreased serum insulin concentrations (-3.2 ± 6.5 vs. -0.2 ± 1.7 µIU/mL, P = 0.01), the homeostasis model of assessment-estimated insulin resistance (-0.8 ± 1.7 vs. -0.02 ± 0.4, P = 0.03), serum triglycerides levels (-11.5 ± 47.3 vs. +10.6 ± 24.3 mg/dL, P = 0.03) and VLDL-cholesterol (-2.3 ± 9.5 vs. +2.1 ± 4.9 mg/dL, P = 0.03), as well as increased quantitative insulin sensitivity check index (+0.01 ± 0.01 vs. +0.001 ± 0.007, P = 0.001) and HDL-cholesterol (+3.4 ± 6.0 vs. -1.3 ± 4.3 mg/dL, P = 0.001).Overall, omega-3 fatty acids and vitamin E co-supplementation for 12 weeks had beneficial effects on inflammatory markers and metabolic profiles in patients with FBD.
Abstract This study was conducted to determine the effects of omega-3 fatty acids and vitamin E co-supplementation on indices of insulin resistance and hormonal parameters in women with polycystic ovary syndrome (PCOS). This randomized double-blind, placebo-controlled trial was done on 68 women diagnosed with PCOS according to the Rotterdam criteria aged 18–40 years old. Participants were randomly assigned into 2 groups to receive either 1 000 mg omega-3 fatty acids from flaxseed oil containing 400 mg α-Linolenic acid plus 400 IU vitamin E supplements (n=34) or placebo (n=34) for 12 weeks. Hormonal parameters were quantified at the beginning of the study and after 12-week intervention. After 12 weeks of intervention, compared to the placebo, omega-3 fatty acids and vitamin E co-supplementation resulted in a significant decrease in insulin (−1.0±3.5 vs. +2.7±6.6 µIU/mL, P=0.004), homeostasis model of assessment-estimated insulin resistance (−0.2±0.8 vs. +0.6±1.5, P=0.005), homeostasis model of assessment-estimated B cell function (−4.3±14.3 vs. +10.5±24.5, P=0.004) and a significant increase in quantitative insulin sensitivity check index (+0.006±0.02 vs. −0.01±0.04, P=0.008). Supplementation with omega-3 fatty acids plus vitamin E led to significant reductions in serum total testosterone (−0.5±0.7 vs. −0.1±0.5 ng/mL, P=0.008) and free testosterone (−1.2±2.1 vs. −0.2±1.7, P=0.04) compared to the placebo group. We did not observe any significant effect of omega-3 fatty acids and vitamin E co-supplementation on fasting plasma glucose and other hormonal profiles. Omega-3 fatty acids and vitamin E co-supplementation for 12 weeks in PCOS women significantly improved indices of insulin resistance, total and free testosterone.
Background. The treatment of candidiasis infections is an important problem in the health care system. This study aimed to investigate the in vitro effect of lavender essential oil and clotrimazole on isolated C. albicans from vaginal candidiasis. Materials and Methods. In this clinical trial, C. albicans isolated from the vaginal discharge samples was obtained. Results. The pairwise comparison showed that lavender and clotrimazole had a significant difference; this difference in the lavender group was lower than clotrimazole. But, after 48 hours, there was no difference seen between groups. There was a significant difference between clotrimazole and DMSO groups. Comparing the changes between groups based on the same dilution, at 24 h and 48 h in clotrimazole group, showed a significant difference two times in the fungal cell count that its average during 48 h was less than 24 h. A significant difference was observed between the two periods in lavender group, only at the dilutions of 1/20 and 1/80. The average fungal cell count after 48 h was also lower in lavender group. Conclusions. Given that the lavender has antifungal activity, this can be used as an antifungal agent. However, more clinical studies are necessary to validate its use in candida infection.
Objective This study was conducted to evaluate the effects of fish oil omega-3 fatty acid supplementation on mental health parameters and metabolic status of women with polycystic ovary syndrome (PCOS).Methods This randomized double-blind, placebo-controlled trial was conducted on 60 women with PCOS, aged 18–40 years old. Participants were randomly assigned into two groups to receive either 2 × 1000 mg/day fish oil omega-3 fatty acid (n = 30) or placebo (n = 30) after lunch for 12 weeks. Metabolic profiles were quantified at baseline and after the 12-week intervention.Results Compared with the placebo, omega-3 fatty acid intake led to a significant improvement in Beck Depression Inventory [β (difference in the mean outcomes measures between treatment groups after intervention) –1.05; 95% CI: –1.84, –0.26; p = .01], general health questionnaire (β –1.68; 95% CI: –3.12, –0.24; p = .02) and depression anxiety and stress scale (β –2.03; 95% CI: –3.60, –0.46; p = .01). Omega-3 fatty acid supplementation significantly decreased serum insulin levels (β –2.09 µIU/mL; 95% CI: –3.77, –0.41; p = .01), homeostasis model of assessment-insulin resistance (β –0.74; 95% CI: –1.13, –0.34; p < .001), total testosterone (β –0.23 ng/mL; 95% CI: –0.39, –0.06; p = .03) and hirsutism (β –0.75; 95% CI: –1.17, –0.33; p = .001), and significantly increased the quantitative insulin sensitivity check index (β 0.01; 95% CI: 0.003, 0.02; p = .008) compared with the placebo. Additionally, omega-3 fatty acid intake resulted in a significant decrease in high sensitivity C-reactive protein (β –1.46 mg/L; 95% CI: –2.16, –0.75; p < .001) and malondialdehyde (β –0.28 µmol/L; 95% CI: –0.52, –0.05; p = .03); also significant rises in plasma total glutathione (β 59.09 µmol/L; 95% CI: 7.07, 111.11; p = .02) was observed compared with the placebo. Omega-3 fatty acid supplementation did not change other metabolic parameters.Conclusion Overall, omega-3 fatty acid supplementation for 12 weeks to patients with PCOS had beneficial effects on mental health parameters, insulin metabolism, total testosterone, hirsutism and few inflammatory markers and oxidative stress.
Summary The role of chromium as a weight loss agent remains questionable, and although previous meta‐analyses findings have reported small reductions in body weight in individuals with overweight/obesity following chromium supplementation, there have been significant limitations with these findings. The objective of this meta‐analysis was to evaluate the current evidence for the efficacy of oral chromium supplementation in individuals with overweight/obesity from randomized controlled trials. Studies were identified by a search of electronic databases from inception to November 2018 and combined and stratified analyses were used. Twenty‐one trials from 19 studies were identified which met all inclusion criteria which were suitable for statistical pooling, and data from 1316 participants were included. Pooled analysis showed significant reductions in anthropometric indices associated with body composition; for weight loss (weighted mean difference [WMD]: −0.75 kg, 95% confidence interval [CI], −1.04, −0.45, P < 0.001), body mass index (WMD: −0.40, 95% CI, −0.66, −0.13, P = 0.003 and body fat percentage (WMD: −0.68%, 95% CI, −1.32, −0.03, P = 0.04) in individuals with overweight/obesity. No changes were detected in controls. Subgroup analysis showed significant improvements in weight loss and body fat percentage, particularly for study durations ≤12 weeks and doses ≤400 μg/d. Chromium supplementation was associated with some improvements in body composition in subjects with obesity/overweight. The effect size was medium and the clinical relevance of chromium as a weight loss aid remains uncertain. Further investigation from larger and well‐designed randomized controlled studies, especially in patients with diabetes, is warranted.
