METHODS: We performed a prospective and paired study in 11 Japanese GDM women requiring insulin for good glycemic control during the third trimester. The women were subjected to test two insulin-meal intervals: 15 min and 30 min. Both regimens were examined in each patient in random order, 2 days apart. Blood glucose was measured by an automated glucose monitor every 2 min. Short-term glucose fluctuations of the two observations were analyzed by two-way ANOVA for repeated measurements with a post hoc t test (p < 0.05). Data were expressed as mean +/- SD. RESULTS: Daily glucose profiles of the two groups showed that their glycemic controls on the days of observation were good and that the two glucose profile curves were superimposable. A transient decrease in glucose (nadir 62 +/- 6 mg/dl) was observed at 6-10 min of meal ingestion in the 30-min regimen, which was significantly different from the glucose fluctuations during the 15-min regimen. The 2-h postprandial glucose levels were similar in both experiments. CONCLUSIONS: In women with tightly controlled GDM during the third trimester, insulin-meal intervals of 15 min are beneficial when compared with 30-min intervals, in that they avoid preprandial hypoglycemia without increasing 2-h postprandial hyperglycemia.","PeriodicalId":79464,"journal":{"name":"The Journal of maternal-fetal medicine","volume":"10 1","pages":"241-245"},"PeriodicalIF":0.0,"publicationDate":"2001-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75895718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These biologically potent compounds are members of the large family of eicosanoids, derived from polyunsaturated fatty acids, principally arachidonic acid, found in the membrane phospholipids of virtually every cell of the human body, accounting for the ubiquity of prostaglandins, which act in a paracrine or autocrine fashion via discrete receptors. The availability of specific prostaglandins in various cells and tissues depends on the presence and activity of specific enzymes that convert a common precursor to the end product, as well as on the rate of enzymatic or spontaneous inactivation of the bioactive compounds. Here we offer a brief review of the regulation of prostaglandin generation in human uterine tissues, focusing on their role in labor and parturition at term and preterm.","PeriodicalId":79464,"journal":{"name":"The Journal of maternal-fetal medicine","volume":"500 1","pages":"223-235"},"PeriodicalIF":0.0,"publicationDate":"2001-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73307360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We conducted a prospective cohort study of 44 parturients. During the second stage of labor, an attending obstetrician performed a vaginal examination to detect fetal occiput position. This was followed by combined abdominal and perineal ultrasound examination. The two methods were compared to the true position. Results were analyzed using Student's t test for quantitative parameters. McNemar's and Fisher's exact tests were applied in order to examine differences between the study groups. Results: The error rate in detecting fetal occiput position was significantly lower using the ultrasound technique (6.8%) compared to vaginal examination (29.6%, p = 0.011).

Near-term ovine fetal swallowing occurs in discrete bouts of activity (at approximately 30-min intervals) in association with fetal electrocortical voltage changes. Thus, swallowing rhythms have been hypothesized to be entrained to fetal neurobehavioral states. In the preterm ovine fetus, electrocortical activity does not demonstrate differentiation into high- and low-voltage periods until 120-130 days' gestation. We sought to quantify patterns of preterm (114 days, 0.75 gestation) ovine fetal swallowing activity and volume, and, in view of the lack of electrocortical pattern changes, to explore whether swallowing activity was regulated by an independent central pacemaker. Methods: Six singleton ovine pregnancies were chronically prepared with fetal and maternal femoral artery and vein catheters. Biparietal electrocortical electrodes were placed on the fetal skull.
