Effect of curcumin nanomicelle on the clinical symptoms of patients with rheumatoid arthritis: A randomized, double-blind, controlled trial.

AIM: Rheumatoid arthritis (RA) is a systemic inflammatory disease. In recent years, new drugs with novel targets have been developed to increase the efficacy of drugs in the treatment of RA. Curcumin has shown potent anti-inflammatory effects and is considered an anti-tumor necrosis factor. The present study was conducted to determine the effect of curcumin nanomicelle on the clinical symptoms of patients with RA. METHODS: This randomized, double-blind, controlled trial selected 65 eligible RA patients and randomly divided them into a curcumin nanomicelle group (n = 30) and a placebo group (n = 35). Curcumin nanomicelle (40 mg) and placebo capsules were administrated to the RA patients 3 times a day for 12 weeks. The Disease Activity Score of 28 joints (DAS-28) and erythrocyte sedimentation rate (ESR) were measured at baseline and after 12 weeks. RESULTS: The DAS-28, tender joint count (TJC) and swollen joint count (SJC) at baseline and the end of the study were not significant between the curcumin nanomicelle and placebo groups. After the intervention, the within-group DAS-28, TJC and SJC in the curcumin nanomicelle and placebo groups reduced significantly compared to the baseline. The difference in changes between the two groups was not significant. Nonetheless, this change was greater in the case group than in the placebo group. No significant changes were observed in terms of ESR between the two groups of RA patients. CONCLUSION: Adding curcumin nanomicelle to the RA patients' medication led to some positive changes in the DAS-28, IJC and SJC, although not significantly.

Investigating and comparing energy and macronutrient intake in female aerobic athletes in two different socio-economic regions.

BACKGROUND: The purpose of this study was to assess nutritional intakes of female aerobic athletes in two different socio-economic classes in city of Isfahan. MATERIALS AND METHODS: The participants of this analytical study were 99 female aerobic athletes aged between 15 and 50 years old who were randomly sampled (50 females in low economic region and 49 females in high economic region). The demographic details were collected by a questionnaire, and anthropometric indexes including height, weight, and waste circumference were measured using a tape measure and a scale. They filled out the 24-hour food recall questionnaire for two consecutive days in order to obtain their nutritional information. To analyze the data, Nutritionist 4 and SPSS18 software were used. RESULTS: The means of energy intake in high and low regions were 1479.19 ± 561.86 and 1300.68 ± 498.354 kcal, respectively. There was no significant difference in terms of energy intake between these two groups (P = 0.98). The means of protein intake in low and high socio-economic classes were 17.41 ± 5.85 and 54.48 ± 6.62, respectively, and no significant differences were observed between these two regions (P = 0/606). The means of carbohydrate intake were 61.85 ± 9.76 and 54.48 ± 6.62 in the low and high socio-economic classes with a significant difference between them (P < 0.001). The mean of carbohydrate intake in the low socio-economic class was considerably higher than that in the high socio-economic class. The means of fat intake were 23.88 ± 8.24% and 30.07 ± 6.68% in the low and high socio-economic classes, respectively, and the means of fat intake in the high socio-economic region was significantly higher than that in the low socio-economic region (P < 0/001). CONCLUSION: The findings of this study indicated that the intakes of fat and carbohydrate were significantly different in the two different socio-economic regions in city of Isfahan. This difference could be attributed to different food patterns in these two regions.
