Pregnancy and perinatal outcomes of interventional ultrasound sclerotherapy with 98% ethanol on women with hydrosalpinx before in vitro fertilization and embryo transfer

To evaluate the pregnancy and perinatal outcomes of ultrasound sclerotherapy with 98% ethanol on women with hydrosalpinx before in vitro fertilization and embryo transfer. A total of 339 women were divided into 4 groups. Group A without a recurrent hydrosalpinx after sclerotherapy (n = 123, 130 cycles), group B having a recurrence of hydrosalpinx after sclerotherapy (n = 34, 39 cycles), group C (n = 47, 50 cycles) with no prophylactic intervention for hydrosalpinx, whereas group D with nonhydrosalpinx tubal factor infertility was served as control group (n = 135, 145 cycles). Pulsatility index, resistance index, the ratio between peak systolic flow and lowest diastolic flow of the uterine arcuate artery on the day of human chorionic gonadotropin administration, and pregnancy and perinatal outcomes were assessed. Thirty-four women (21.7%) experienced hydrosalpinx recurrence after sclerotherapy. The rates of embryo implantation (8.8%), clinical pregnancy (16.0%), and live birth (10.0%) in group C were significantly lower than those in group A (26.4%, 43.1%, 33.8%), group B (24.5%, 38.5%, 28.2%), and group D (30.0%, 50.3%, 39.3%), respectively. The pulsatility index, resistance index, and the ratio between peak systolic flow and lowest diastolic flow of the uterine arcuate artery in group C were significantly higher than those in the other 3 groups. No significant differences in the rate of preterm birth, the rate of low birthweight newborns, and birth defects were found among the 4 groups. Ultrasound sclerotherapy on women with hydrosalpinx could improve the outcomes of in vitro fertilization embryo transfer by improving the blood flow of the uterine arcuate artery. Interventional ultrasound sclerotherapy has no adverse effect on perinatal outcomes.

Association between the rate of low-birth weight newborns and the incidence of end-stage renal disease in 47 prefectures in Japan

An ecological study is a useful epidemiologic tool for public health surveillance and establishment of a new hypothesis. Here, we used an ecological study to analyze the association between birth weight and end-stage renal disease (ESRD). We performed ecological regression analysis by using data obtained from the national database of Japan. The data include regional incidence of ESRD beginning maintenance dialysis therapy, regional rate of low-birth weight (LBW) newborn babies of all newborn babies, the average birth weight of newborns, the body mass index (BMI) score, the prevalence of diabetes mellitus, and the amount of payment for drugs, in the 47 prefectures of Japan. The mean regional rates of LBW newborn babies from 1999 to 2008 statistically correlated with the mean incidences of ESRD during the same time periods in each prefecture. The correlation coefficients between the yearly rate of LBW newborns and the yearly incidence of ESRD in each prefecture became higher after statistically considering the effects of the cost per resident for prescriptions of angiotensin II receptor blocker and angiotensin converting enzyme inhibitor. Furthermore, the final model predicting the regional incidence of ESRD by a stepwise multiple regression analysis consisted of the average BMI score and the rate of LBW newborns in each prefecture. Although this study cannot explain the reason for this unexpected correlation between the regional rate of LBW babies and the regional incidence of ESRD at the same time points, the statistically significant correlations shown in this study should be taken into consideration.

Birth Outcomes of Pre-Eclamptic Pregnant Women With Vitamin E Supplementation A Population-Based Study

Objectives. To study the efficacy of vitamin E supplementation for the reduction of preterm birth/low birth- weight newborns in pre-eclamptic pregnant women. Design. Comparison of the rate of preterm birth and low birthweight in pre-eclamptic pregnant women with or without vitamin E treatment. Setting. Hungarian Case-Control Surveillance Sys- tem of Congenital Abnormalities, 1980-1996. Population. Newborn infants in Hungarian population. Methods. Medically recorded pre-eclampsia and birth outcomes of pregnant women were evaluated. Main outcome measures. Preterm birth, low birthweight. Results. There was no lower incidence of pre-eclampsia after vitamin E treatment. Pregnant women with pre-eclampsia and without vitamin E treatment had a higher rate of preterm births (10.4% vs. 9.3%) and low birthweight newborns (7.8% vs. 5.6%) than the reference sample of 34,928 pregnant women without pre-eclampsia and without vita- min E treatment. The newborns of 936 pregnant women with pre-eclampsia and without vitamin E treatment had higher rate of preterm birth (10.4% vs. 8.6%; OR with 95% CI: 0.8, 0.7-0.9) than 81 pregnant women with pre-eclampsia but with vitamin E treatment. However, the rate of low birthweight newborns was somewhat but not significantly higher (8.6% vs. 7.8%; OR with 95 CI: 1.1, 0.8-1.4) in pregnant women with pre-eclampsia and with vitamin E treatment. There was very high rate of threatened abortion (45.7% vs. 15.3%) and threatened preterm delivery (27.2% vs. 13.5%) in 81 pre- eclamptic pregnant women with vitamin E treatment compared to the reference group. Conclusions. Vitamin E treatment reduced the rate of preterm birth in pregnant women with pre-eclampsia but not the rate of low birthweight newborns.
