Effects of body electroacupuncture on plasma leptin concentrations in obese and overweight people in Iran: a randomized controlled trial.

BACKGROUND: The prevalence of obesity, a major public health problem, is increasing in many countries, including Iran. Leptin, a peptide hormone that is released from adipocytes, is a major factor in appetite regulation. Levels of plasma leptin increase with increased body fat mass (BFM). Research has found acupuncture to be effective both in weight loss and suppression of appetite. Although a few studies have reported the effect of body and ear acupuncture on leptin levels, researchers have performed few studies on the effect of body electroacupuncture in humans. OBJECTIVE: The research team examined the effects of body electroacupuncture and a low-calorie diet on plasma leptin in obese and overweight individuals with an excess (phlegm-dampness or phlegm-heat) or deficiency (spleen/stomach qi deficiency or primary qi deficiency) pattern according to Chinese medicine. DESIGN: The research team randomly assigned participants to one of two groups, intervention or control. SETTING: This study occurred in the nutritional clinic at Ghaem Hospital in Mashhad, Iran. PARTICIPANTS: Participants were individuals (N = 86) between 18 and 65 years of age with body mass indexes (BMI) between 25 and 45 kg/m2. INTERVENTION: The intervention group (n = 47) received actual electroacupuncture, and the control group (n = 47) received sham acupuncture. Both groups consumed a low-calorie diet for 6 weeks. OUTCOME MEASURES: The research team measured plasma leptin, BFM, body weight (BW), and BMI before and after treatment. RESULTS: For participants in the intervention group with both the excess and the deficiency patterns, the research team found a significant reduction in plasma leptin (24.96%, P = .001) and BFM (8.29%, P = .001). In the control group, the team found a less significant reduction in leptin and BFM. The difference between the two groups was significant for leptin (P = .03) but not for BFM (P = .8). CONCLUSIONS: While body electroacupuncture with a low-calorie diet can reduce plasma leptin concentration, the mechanism will require further clarification.

Misoprostol alone or in combination with methotrexate for termination of pregnancy at first trimester.

Abortion is an important problem in obstetrics throughout the world. The common and standard method for pregnancy termination at first trimester is surgery (curettage). Nowadays, an effective method of pregnancy termination at first trimester is medical treatments. The aim of this study is to compare misoprostol alone or in combination with methotrexate for pregnancy termination at first trimester. This study is a randomized clinical trial. A total of 200 pregnant women at first trimester were randomizedly divided into two groups for termination of pregnancy. The first group received 800 µg vaginal misoprostol. If conceptus residual remained, the same dose of misoprostol was repeated. The second group received 50 mg/m² intramuscular methotrexate, and then 800 µg vaginal misoprostol was administered after 72 h. If conceptus residual remained, the same dose of misoprostol was repeated after 24 h. Abdominal ultrasonography was performed at seventh day for both groups. Should conceptus residual remained or if pregnancy continued, curettage was performed. The results were analyzed statistically in terms of chi-square, and student's t-test, using the SPSS software. A P-value equal or smaller than 0.05, was considered statistically significant. In this study, 83% of the first group and 81% of the second group had successful abortion. There was a significant correlation between the dose of misoprostol and abortion (P = 0.001) and between type of pregnancy and need for curettage (P < 0.000) in both groups, but there was no significant correlation between gestational age and the numberof doses administered (P = 0.932).In conclusion it seems that pregnancy termination by misoprostol alone or in combination with methotrexate is a safe and cost-effective method.
