Efficacy of Acupuncture on Pain Severity and Frequency of Calf Cramps in Dialysis Patients: a Randomized Clinical Trial.

Background: Patients with chronic kidney disease, as a common disorder, usually necessitate the implementation of hemodialysis. Muscle cramps are one of the most disabling complications affecting their quality of life. Objectives: We aimed to investigate the efficacy of acupuncture as a safe alternative to the management of pain severity and frequency of calf cramps in dialysis patients compared to a control group. Methods: Fifty dialysis patients experiencing calf cramps who met the eligibility criteria were randomly allocated to two groups. Group A received routine management, including analgesic consumption, stretching exercises, and nine acupuncture sessions, including acupoints BL57, GV26, CV4, CV6, LV3, KI 1, LU7, LU9, and GB34. Group B underwent sham acupuncture therapy at locations other than the primary acupoints in addition to following the specified routine management. The pain severity was measured using the visual analog scale (VAS), and the daily frequency of calf cramps was evaluated at baseline and one month after treatment completion. Results: VAS scores and the frequency of calf cramps were improved one month after treatment completion in both groups. However, the improvement was significant in group A (p < 0.001), while it was not statistically significant in group B (p > 0.05). There was also a significant difference between both groups regarding reducing pain and the frequency of calf cramps, which showed the efficacy of acupuncture compared to the control group (p < 0.0001). Conclusion: Acupuncture can decrease pain and frequency of calf cramps in dialysis patients.

Prudent and traditional dietary patterns are positively and negatively associated with bone mineral density in Iranian adults, respectively.

To assess the association of dietary patterns and bone mineral density (BMD), 340 healthy Iranian adults (mean age 41.5 ± 7.7 y; 79.1% female) participated in this cross-sectional study. Lumbar spine and femoral neck BMDs were measured using dual-energy X-ray absorptiometry. Dietary intakes were evaluated by a valid and reliable 168-item food frequency questionnaire, and three major dietary patterns were identified using principal component factor analysis. Mean values for lumbar spine and femoral neck BMDs in participants were 0.96 ± 0.13 and 0.92 ± 0.12 g/cm2, respectively. After controlling for age, body mass index, physical activity, energy intake, sunlight exposure, gender, education, employment status, supplement intake, and smoking in the analysis of covariance models, multivariable adjusted means of femoral neck BMD of participants in the highest tertile of the prudent pattern score (rich in green leafy vegetables, other vegetables, tomatoes, yellow vegetables, fruits and fruit juices, olives, nuts, fish, low-fat dairy products, and Doogh) were significantly higher than those in the lowest tertile (mean difference and 95% CI: 0.043 [0.003; 0.083] g/cm2, P = 0.032). In contrast, multivariable adjusted means of lumbar spine BMD of participants in the highest tertile of the traditional pattern score (high in Abgoosht, vegetable oils, salt, legumes, pickles, cruciferous vegetables, refined grains, potatoes, and organ meats) were significantly lower than those in the lowest tertile (mean difference and 95% CI: -0.057 [-0.098; -0.015] g/cm2, P = 0.003). The Western pattern was not associated with BMD. In conclusion, the prudent and traditional dietary patterns are positively and negatively associated with BMD in Iranian adults, respectively.

Effect of vitamin C supplementation on postprandial oxidative stress and lipid profile in type 2 diabetic patients.

Diabetes mellitus is one of the most wide spread endocrine disorders and an important developing health problem in the world. Cardiovascular disease is a common complication of type 2 diabetes. Several risk factors for coronary heart disease cosegregate in type 2 diabetes, including hyperglycemia, hyperlipaemia, increases production of free radical and decrease in antioxidant defense system. In this study we evaluated the effect of vitamin C supplementation on fasting and postprandial oxidative stress and lipid profile in type 2 diabetic patients. 30 patients with type 2 diabetes from Nader Kazemi Clinic, Shiraz, Iran were randomly divided into 2 groups; vitamin C treatment group (1000 mg d(-1)) and placebo group from May to September 2010. Fasting and postprandial lipid profile and Malondialdehyde (MDA) level were measured at the beginning of the study and after six weeks of supplementation. Data analysis was carried out using Mann-Whitney U test with p < 0.05 being significant by SPSS software version 16.The result of the study showed a significantly decrease in fasting (p = 0.006) and postprandial MDA (p < 0.001) in vitamin C group compare to placebo group but not in lipid profile. This study suggests that vitamin C supplementation can decrease fasting and postprandial oxidative stress and may prevent diabetes complication.

The role of iron deficiency in persistent goiter.

BACKGROUND: Iodine deficiency has been identified as a significant public health problem in Iran. The main strategy for controlling iodine deficiency was nationwide salt iodination. Over 10 years after starting this program, goiter is still endemic in school children. Iron deficiency may have interfered with the iodine intervention program. The objective of the present study was to evaluate the relationships between iron status, thyroid hormone profile, and the prevalence of goiter 11 years after implementation of the salt iodination program. METHODS: In this study which was conducted in Marvdasht, Shiraz, 1188 students aged eight to 13 years were enrolled. Goiter was graded according to the classification by the World Health Organization (WHO). Serum concentrations of thyroid hormones and thyroid stimulating hormone were determined using commercial kits. The urinary iodine level was measured using the digestion method. RESULTS: Goiter was endemic (39.6%); the majority of participants had grade 1 thyromegally. Despite the endemic status of goiter in southern Iran, the urine content of iodine reflected a normal iodine intake. The prevalence of iron deficiency was 16.4%. The iron-deficient patients had a significantly higher thyroid stimulating hormone level and lower free T4 concentrations than those with a normal serum ferritin level (P<0.001). CONCLUSION: Iron supplementation may improve thyroid metabolism in children but we still have to investigate the role of other goitrogens in this area.
