ABSTRACT

AIM: The aim of this study was to investigate the serum oxidative stress markers, antioxidant enzyme and tumor necrosis factor-α (TNF-α) levels at 24-28 weeks of gestation and to evaluate the predictive value of them on the subsequent treatment protocol in gestational diabetes mellitus (GDM). METHODS: A total of 58 GDM patients (30 treated with only conventional healthy dietary recommendation (CHDR), 28 treated with insulin) and 30 healthy pregnant women at 24-28 weeks of gestation, were enrolled in this prospective case-control study. The oxidative status, antioxidant enzyme and TNF-α levels were evaluated to determine if there is an association with the need of insulin therapy for glycemic control by using multivariable logistic regression analysis. RESULTS: TNF-α (OR=11.976, 95%CI: 2.441-58.754, P=0.002) and total antioxidant status (TAS) (OR=12.769, 95%CI: 2.464-66.182, P=0.002) were found to be predictive for GDM at 24-28 weeks of gestation. Besides, further evaluation considering the treatment modality showed that increased TNF-α (OR=18.615, 95%CI: 2.338-148.240, P=0.006) and lower TAS levels (OR=99.471, 95%CI: 2.865-3 453.061, P=0.011) were independent predictors of the need for insulin treatment in GDM patients. CONCLUSIONS: Increased TNF-α levels and low TAS are significantly associated with the increased risk of insulin requirement for achieving good glycemic control in GDM.

ABSTRACT

aullimary Investigation: The cause of discordance in dichorionic diamniotic (DD) twins is still unknown. The authors aimed to compare decorin (DCN) and oxidative/antioxidative state levels between the placentas of discordant and concordant twins. MATERIALS AND METHODS: Prospective study of 43 spontaneous DD twin pregnancies included and placentas samples taken from each twin and prepared for homogenization. Total oxidant/antioxidant status levels in placental tissue were determined by automated colorimetric method. Decorin levels were detected by using ELISA method; 23 of these were discordant and 20 of them were concordant. RESULTS: DCN levels in the placentas of the low birth-weight twins were significantly lower than the levels of the placentas of appropriate gestational age twins (p = 0.006). There were no statistically significant differences in total antioxidant status (TAS), total oxidant status (TOS), or arylesterase (ARES) levels in discordant (p = 0.631, p = 0.370, and p = 0.079, respectively) and in the placental DCN, TAS, TOS, or ARES levels of the concordant twins (p = 0.407, p = 0.035, p = 0.194, and p = 0.979, respectively). When the authors compared the twins of similar birth weight, the DCN, TAS, and TOS levels were significantly lower in the discordant twins (p < 0.001, p < 0.001, and p = 0.002, respectively). CONCLUSIONS: Decreased levels of DCN in discordant twin fetuses compared to the same birth weight-concordant twins shows that it contributes to disease pathogenesis.

ABSTRACT

This study aims to evaluate the effects of plasma beta endorphin level and exercise on migrainous headache. Forty patients with migrainous headache without aura (MWOA), firstly exercised on a treadmill and afterwards were asked to continue an aerobic home exercise program for six weeks. On evaluation, basal plasma beta endorphin level was negatively correlated with total duration of attacks in the last month period (P = 0.01). Exercise was found to have beneficial effects on all migraine parameters (P < 0.0001) and to increase beta endorphin levels after the treadmill practice (P < 0.0001) and after the home exercise program except four patients not regularly attended to the program (P < 0.0001). Any of the changes in headache parameters was not correlated with the change in beta endorphin level. However, pre-exercise beta endorphin level was found to be negatively correlated with the changes in the number of attacks (P < 0.05) and total duration of attacks (P = 0.01) and also with the change in beta endorphin level due to exercise (P < 0.0001). As a result, this study emphasizes the beneficial effect of exercise on migrainous headache, especially in patients with lower basal beta endorphin level.
