Adverse pregnancy outcomes in rural Maharashtra, India (2008–09): a retrospective cohort study

Abstract Background The association between bacteriuria and adverse pregnancy outcomes has been extensively described. The current practice of screening all pregnant women for bacteriuria is challenged by recent studies. We aimed to evaluate pregnancy outcomes among women with a positive urine culture, to assess the significance of positive urinary nitrites in this setting. Methods This was a retrospective cohort study at the emergency department (ED) of the Helen Schneider Hospital for Women, Israel, during 2014–2018. This included all gravida women >18 years old within the 20th week of pregnancy or above, admitted to the ED with diverse complains, who had urinalysis collected and subsequently had a positive urine culture. Clinical and obstetric characteristics were stratified by positive vs. negative nitrites in urinalysis. The primary outcome was premature delivery, and the secondary outcomes were a composite outcome of all recorded pregnancy complications and the significance of urinalysis in predicting urinary tract infection (UTI). Results Overall, 874 pregnant women with a positive urine culture were included. Of them, 721 (79%) patients had a negative nitrite in their urine exam (NNU-group) and 153 (21%) had a positive nitrite in their urine exam (PNU-group). Escherichia coli was the most common pathogen, with significantly higher rates of growth in the PNU-group vs. NNU-group [129 (84.3%) vs. 227 (38.4%), P < 0.001]. Premature delivery was recorded with no association of symptomaticity or nitrite status. Among symptomatic women with classic symptoms of UTI, PNU was significantly associated with decreased risk for major peripartum complications [odds ratio (OR) with 95% confidence interval (CI) of 0.22 (0.05–0.94)]. Conclusion Our findings support that PNU among symptomatic pregnant women with UTI-related symptoms was associated with lower risk of developing major adverse obstetrical outcomes.

Abstract Background Data on pregnancy outcomes in Primary Sjogren's syndrome (pSS) women are scarce, and results have been conﬂicting. The aim of our study is to analyze the adverse pregnancy outcome in patients with pSS. Methods This was a retrospective cohort study conducted at a tertiary medical center located in Chengdu, Sichuan, China, from May 2013 to November 2018. The relevant medical records of all pregnant women were retrospectively reviewed. Logistic regression analyses were performed to compute crude odds ratios (crude OR) with 95% confidence intervals (CI) for maternal and fetal outcomes. Adjusted odds ratios (aOR) were estimated by logistic regression adjusted for confounders. Results Women with pSS had a significantly higher incidence of pre-eclampsia (aOR 11.49, 95% CI 1.65-79.98), PPROM (aOR 5.09, 95% CI 1.14-22.63). Compared to general population, pregnant women with pSS were at increased risks of fetal loss (aOR 15.06, 95%CI 1.19 to 191.11), and a higher risk of fetal growth restriction (aOR 15.69, 95%CI 1.61 to 153.33), preterm birth (aOR 5.52, 95%CI 1.83 to 16.65), a cesarean section (aOR 6.53, 95%CI 3.18 to 13.42) and a neonatal intensive care unit admission (aOR 12.86, 95%CI 1.88 to 87.82) after adjusting for confounding factors. The rate of congenital heart block in the pSS group was 4.7%. Conclusions Pregnant women with pSS were at increased risk of having adverse pregnancy outcomes. Women with pSS require prenatal counseling to explain the risks involved and well control of pSS condition before conception and a close antenatal monitoring should be performed by both rheumatologists and obstetricians.

ObjectiveTo investigate the association between maternal pregestational blood glucose level and adverse pregnancy outcomes.DesignRetrospective cohort study.SettingThis study was conducted in the Chongqing Municipality of China between April 2010 and December 2016.ParticipantsA total of 60 222 women (60 360 pregnancies) from all 39 counties of Chongqing who participated in the National Free Preconception Health Examination Project and had pregnancy outcomes were included.Primary outcome measuresAdverse pregnancy outcomes included spontaneous abortion, induced abortion or labour due to medical reasons, stillbirth, preterm birth (PTB), macrosomia, large for gestational age, low birth weight (LBW) and small for gestational age.ResultsOf the 60 360 pregnancies, rates of hypoglycaemic, normoglycaemia, impaired fasting glycaemia (IFG) and diabetic hyperglycaemic before conception were 5.06%, 89.30%, 4.59% and 1.05%, respectively. Compared with women with normoglycaemia, women with pregestational glucose at the diabetic level (≥7.0 mmol/L) might have a higher rate of macrosomia (6.18% vs 4.16%), whereas pregestational IFG seemed to be associated with reduced risks of many adverse outcomes, including spontaneous abortion, induced abortion due to medical reasons, PTB and LBW. After adjusting for potential confounders, pregestational diabetic hyperglycaemic was remained to be significantly associated with an increased risk of macrosomia (adjusted risk ratio 1.49, 95% CI 1.07 to 2.09). Abnormal maternal glucose levels before pregnancy (either hypoglycaemic or hyperglycaemic) seemed to have no significant negative effect on spontaneous abortion or induced abortion due to medical reasons.ConclusionAlthough without overt diabetes mellitus, women with once diabetic fasting glucose level during their preconception examinations could be associated with an increased risk for macrosomia. Uniform guidelines are needed for maternal blood glucose management during pre-pregnancy care to improve pregnancy outcomes.
