Abstract
Background: The prevalence of gestational diabetes is increasing among pregnant women. It is associated with an increased risk of congenital heart disease, including hypertrophic cardiomyopathy. The aim of this study was to evaluate the effect of maternal diabetes control (based on HbA1c) on their hypertrophic cardiomyopathy in newborns.
Methods: This case-control study was performed on 60 neonates born in Afzalipour Hospital (Kerman University of Medical Sciences) from May to November 2014 in two groups of eligible infants using the convenience sampling method. Information about the age, sex, weight, gestational age, maternal age, obstetric history, gestational diabetes through the checklist were collected. Then Doppler echocardiography, M- Mode, Doppler tissue was conducted on two groups. Echocardiographic criteria including ventricular septal thickness and blood HbA1c mothers in both groups were compared. To compare quantitative and qualitative variables between the two groups’ Independent samples t‐test and Chi-square test was used. A significant level of 0.05 was considered in all of the statistical samples and SPSS software, ver. 20 (IBM, Armonk, NY, USA) was used to analyze the data.
Results: In this study, the birth weight of infants and the age of mothers did not differ between two groups (Respectively P=0.56, P=0.08) However, HbA1c was significantly higher in the infants of mothers with impaired glucose tolerance test (GTT) (P<0.001). In infants of mothers with impaired GTT, ventricular septal thickness was significantly higher than the healthy controls (P=0.03), Also there was a significant difference between two groups in tissue Doppler criteria (Ea) (P=0.04), In other echocardiographic criteria, no significant differences were reported (The LA/AO, LVPWT, LVEF, LVEF, LVFS, LVFS, LVEDd, LVESd, Sa and Aa, All P-values were ≥ 0.05).
Conclusion: Diabetes mellitus of mothers causes several complications in their infants. The prevalence of cardiomyopathy hypertrophy is higher in babies whose mothers have higher levels of HbA1c and a sign of poor control of blodd glucose level during pregnancy. |

Abstract
Background: According to the direct connection between congenital hypothyroidism and iodine deficiency in pregnant women, also relatively high incidence of congenital hypothyroidism in some areas of Kerman province, especially Raver district located in North of Kerman province, this study was performed to determine and compare the urinary iodine concentration (UIC) in pregnant women referring to health centers.
Methods: This cross-sectional study was done during March 2014 and May 2015. Inclusion and exclusion criteria to be considered and UIC were measured by spectrophotometry in 384 and 374 pregnant women in Ravar and Kerman cities, Iran. Sampling method for this study was all of pregnant women in Ravar and random stratified sampling in Kerman. data were collected using a structured questionnaire. All statistical analyses were performed using SPSS Software, version 20.0 (IBM SPSS, Armonk, NY, USA). Chi-square test, Pearson's correlation coefficient and Logistic regression were used for associations and differences.
Results: The mean UIC was 200.21 µg/L in pregnant women of Ravar and 238.79 µg/L in pregnant women of Kerman. 22.7% of pregnant women were with low concentrations of iodine, 57.8% within the normal range and 19.5 percent were with high iodine concentrations in Ravar. While 5.3 percent of pregnant women were with low concentrations of iodine, 54.5% were within the normal range and 40.1% were with high UIC in Kerman. There were no significant differences between demographic variables and UIC in the two regions (P> 05/0). Multivariate regression models showed significant connections between the residence and UIC pregnant women (P< 0.001).
Conclusion: The results of this study showed that UIC in pregnant women of Ravar was significantly lower than Kerman and the place of living can be considered as a predictor of UIC in pregnant women.
