Waist circumference in predicting gestational diabetes mellitus

Background: To evaluate waist circumference (WC) measured at 20-24 weeks of gestation as a predictor of gestational diabetes mellitus (GDM).Methods: This cross-sectional study included 240 women at 20-24 weeks of gestation. At enrollment, WC was measured, and both prepregnancy and gestational body mass index (BMI) were estimated. According to the results of 75-g oral glucose tolerance test (OGTT) performed at 24-28 weeks, subjects were allocated into two groups, non-GDM and GDM. WC sensitivity and specificity, and odds ratios (OR) and 95% confidence intervals for BMI and WC were estimated, and a receiver operating characteristics curve was generated.Results: Of the 240 pregnant women enrolled, 31 (13%) had GDM. Prepregnancy BMI (OR = 4.21), gestational BMI (OR = 3.17) and WC at 20-24 weeks (OR = 4.02) correlated with GDM risk. At 20-24 weeks, a WC of 85.5-88.5 cm was the optimal cutoff point for predicting GDM (Sens/Spec balance between 87.1/41.1% and 77.4/56.9%).Conclusion: At 20-24 weeks of gestation, WC values in the range of 86-88 cm showed to be a good performance in predicting GDM.

Estresse oxidativo, alterações metabólicas e renais decorrentes da elevada ingestão de sacarose: efeito protetor da N-acetilcisteína (NAC)

Oxidative stress is related with physiopathology of diabetes mellitus type II and with its secondary complications, such as diabetic nephropathy. Thus, the purpose of this study was to examine the effects of n-acetylcysteine NAC, an antioxidant from Allium cepa, on oxidative stress, morphometrical and nutritional parameters and basal metabolism and energetic substrate utilization, serum glucose and oral glucose tolerance test (OGTT), and renal function of high-sucrose intake rats. Animals were initially divided into three groups. Rats in the control group (C; n=10) were given free access to a standard chow and water; (S; n=10) group received standard chow and 30% sucrose in its drinking water; (SN; n=5) group received standard chow and 2g/L NAC and 30% sucrose in its drinking water. After 25 days of treatments, rats were submitted to indirect calorimetry in fasted and feed states. After 30 days of treatments, rats from C and S groups were divided into four groups of five rats each. The (CC) and (SS) groups were given an intra-gastric dose 0,6mL saline (0,9%NaCl) and the (CNAC) and (SNAC) groups were treated with a intra-gastric dose of 0,6mL NAC (160g/day), and then everybody received a intra-gastric dose of glucose solution (20%) for the OGTT. Animals of S and SN groups have higher liquid consumption and lower food consumption than C group. Calorimetric analyses confirm that despite of the final body weight had not statistical difference among groups, S group have lower resting metabolic rate when compared to C and SN animals. Besides, S group has higher respiratory quotient, higher carbohydrate oxidation and lower lipid oxidation, both in fasted and feed states, than C and SN groups, evidencing the beneficial effect of NAC. Fasting plasma glucose is increased in SS and SNAC animals when compared to CC and CNAC, however SN group has glicemic level at 30 min before OGTT decreased when ...(Complete abstract click electronic access below)
