Abstract Objective:, Our aim was to determine the obstetrics outcomes of patients with positive 1-h glucose challenge test (GCT), but negative diagnostic test for gestational diabetes. Methods:, Pregnancy records of 409 pregnants were reviewed. Patients were screened for gestational diabetes mellitus (GDM) with one-hour 50 g glucose challenge test (GCT) at 24,28 weeks of gestation. Patients with glucose challenge tests values , 130 mg/dL were refered for the 3 h, 100-g oral glucose tolerance test (OGTT). Positive GCT but negative for OGTT group (Group A) were compared retrospectively with the group of negative GCT (Group B) for obstetrics outcomes. Result:, GDM and impared glucose tolerance (IGT) were diagnosed in 33 (7.6%) and 46 (10.5%) patients, respectively. We identified 141 (34.4%) patients with positive GCT but negative for OGTT (Group A) and 189 (46.2%) patients with negative GCT (Group B). Gestational weight gain, polyhydramnios, family history of diabetes mellitus were significantly higher in group A than group B (P < 0.05). Prevalance of preterm labor, hypertension, cesarean delivery, mean birthweight, proportion of babies admitted to neonatal intensive care unit were similar in both groups. Conclusion:, There are some differences for pregnancy outcomes between pregnants with positive GCT but negative for OGTT and negative GCT. These patients should be followed up carefully during the antepartum and intrapartum period. [source]

Background:, Torres Strait Islander population has a high prevalence of type 2 diabetes (T2DM). Aims:, To review pregnancy data of women and their newborns living in the Torres Strait area. Methods:, All medical charts of mothers and their neonates delivered in two one-year periods (1999 and 2005/2006) were reviewed. The initial screening test for diabetes in pregnancy (DIP) was a random blood glucose level followed by an oral glucose challenge test in 1999 and from 2000 an oral glucose tolerance test. Results:, Diabetes in pregnancy increased by 4.3,13.3% and T2DM by 0.8,4.6%. During the two periods, 258 and 196 mothers delivered respectively 84,92% by midwives/general practitioners at the local hospital and 7,16% by midwives/obstetricians at the regional hospital; in 2005/2006, 58% of women with DIP delivered at the regional hospital. Screening increased from 89.2 to 99.5%. DIP mothers were older and heavier with more hypertension and previous miscarriages. Parity decreased in the DIP mother during the two periods. Caesarean section was five times more common for DIP in 2005/2006 versus non-DIP, while in 1999, there was no difference. In 1999, the DIP infants were heavier, longer (P = 0.053) and had a larger head circumference not seen 2005/2006. There was more neonatal trauma, hypoglycaemia and IV dextrose in the DIP infants. Breastfeeding numbers increased in DIP. In 2005/2006, follow-up of gestational diabetes occurred in 47% (all normal). Conclusion:, A massive increase in DIP was seen. The neonatal outcomes improved slightly. There is need for improvement in follow-up of gestational diabetes. [source]

Women's and health professionals' preferences for prenatal testing for Down syndrome in Australia

Abstract Aim:, To describe and compare women's and health professionals' preferences for prenatal screening tests for Down syndrome. Design:, Cross-sectional questionnaire survey. Participants and setting:, Women (n = 322) attending for a glucose challenge test at 26 weeks gestation and health professionals (266 midwives and 34 obstetricians) at the Royal Women's Hospital, Melbourne, between 13 December 2002 and 30 April 2003. Outcome measures:, The relative value participants attach to attributes of Down syndrome screening tests as determined by conjoint analysis and ranking scales. Results:, Women and health professionals shared similar relative values regarding the importance of detection rate of screening tests, according to coefficients from conjoint analysis models. However, health professionals placed higher relative values on timing of prenatal tests and risk associated with the subsequent diagnostic test than did women. Comparison of coefficients suggests that, compared with health professionals, women would wait longer and accept a greater decrease in detection rate for a test if it was safer. Using the more traditional ranking scale, the safest test was ranked first by 56% of women while 47% of health professionals ranked a test with the highest detection rate first. Equal proportions (,10%) in both groups ranked the earliest test first. Conclusion:, There is a general agreement between pregnant women and health professionals regarding the relative importance they attach to different attributes of a test. However, health professionals appeared to favour earlier timing of tests while women placed greater emphasis on safety. Utilising two different measures of preference demonstrated the complexity of decision-making. [source]
