Abstract
AIMS/INTRODUCTION A debate exists on the relation of adverse pregnancy outcomes with glycemic levels in early pregnancy. We aimed to investigate the association of maternal characteristics including post-load glucose and first-trimester HbA1c test results with adverse pregnancy outcomes in women without gestational diabetes mellitus. MATERIALS AND METHODS A dataset (January 2011 and September 2017) from a hospital prenatal clinic was explored to find the important predictors of adverse pregnancy outcomes using maternal characteristics and glucose assessments in mothers without gestational diabetes. We used two machine learning algorithms to capture nonlinearity in selecting important maternal characteristics and developed predictive models for each outcome. In total, 1,618 pregnant women were included in the analytic dataset with a mean (SD) age of 26.8 (3.5) years and gravida of 1.7 (0.9). RESULTS Important associations were detected between maternal features and primary cesarean section, fetal distress, premature rupture of membranes, macrosomia, small or large for gestational age, APGAR <7 at 1 or 5 min, hyperbilirubinemia, and poly- or oligo-hydramnios. Overall, the predictive models showed good performance and large areas under the curves (0.732, 0.765, 0.646, 0.651, 0.730, 0.646, 0.684, 0.716, and 0.678, respectively). Specifically, they had high positive likelihood ratios. CONCLUSIONS High glucose levels were associated with adverse pregnancy outcomes. Post-load glucose was the most reliable test for predicting the outcomes. Overall, fasting blood sugar was of more predictive value than HbA1c. Our study showed that further research should account for the nonlinearity and interactions inherent in the data.

Perinatal and early life factors and asthma control among preschoolers: a population-based retrospective cohort study. BMJ Open Respir Res 2023; 10:e001928. [PMID: 37748808 PMCID: PMC10533801 DOI: 10.1136/bmjresp-2023-001928] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Accepted: 08/30/2023] [Indexed: 09/27/2023] Open
Abstract
BACKGROUND Preventing poor childhood asthma control is crucial for short-term and long-term respiratory health. This study evaluated associations between perinatal and early-life factors and early childhood asthma control. METHODS This retrospective study used administrative health data from mothers and children born 2010-2012 with a diagnosis of asthma before age 5 years, in Alberta, Canada. The outcome was asthma control within 2 years after diagnosis. Associations between perinatal and early-life factors and risk of partly and uncontrolled asthma were evaluated by multinomial logistic regression. RESULTS Of 7206 preschoolers with asthma, 52% had controlled, 37% partly controlled and 12% uncontrolled asthma 2 years after diagnosis. Compared with controlled asthma, prenatal antibiotics (adjusted risk ratio (aRR): 1.19; 95% CI 1.06 to 1.33) and smoking (aRR: 1.18; 95% CI 1.02 to 1.37), C-section delivery (aRR: 1.11; 95% CI 1.00 to 1.25), summer birth (aRR: 1.16; 95% CI 1.00 to 1.34) and early-life hospitalisation for respiratory illness (aRR: 2.24; 95% CI 1.81 to 2.76) increased the risk of partly controlled asthma. Gestational diabetes (aRR: 1.41; 95% CI 1.06 to 1.87), C-section delivery (aRR: 1.18; 95% CI 1.00 to 1.39), antibiotics (aRR: 1.32; 95% CI 1.08 to 1.61) and hospitalisation for early-life respiratory illness (aRR: 1.65; 95% CI 1.19 to 2.27) were associated with uncontrolled asthma. CONCLUSION Maternal perinatal and early-life factors including antibiotics in pregnancy and childhood, gestational diabetes, prenatal smoking, C-section and summertime birth, and hospitalisations for respiratory illness are associated with partly or uncontrolled childhood asthma. These results underline the significance of perinatal health and the lasting effects of early-life experiences on lung development and disease programming.

Abstract
OBJECTIVE To investigate the association between gestational diabetes mellitus and adverse outcomes of pregnancy after adjustment for at least minimal confounding factors. DESIGN Systematic review and meta-analysis. DATA SOURCES Web of Science, PubMed, Medline, and Cochrane Database of Systematic Reviews, from 1 January 1990 to 1 November 2021. REVIEW METHODS Cohort studies and control arms of trials reporting complications of pregnancy in women with gestational diabetes mellitus were eligible for inclusion. Based on the use of insulin, studies were divided into three subgroups: no insulin use (patients never used insulin during the course of the disease), insulin use (different proportions of patients were treated with insulin), and insulin use not reported. Subgroup analyses were performed based on the status of the country (developed or developing), quality of the study, diagnostic criteria, and screening method. Meta-regression models were applied based on the proportion of patients who had received insulin. RESULTS 156 studies with 7 506 061 pregnancies were included, and 50 (32.1%) showed a low or medium risk of bias. In studies with no insulin use, when adjusted for confounders, women with gestational diabetes mellitus had increased odds of caesarean section (odds ratio 1.16, 95% confidence interval 1.03 to 1.32), preterm delivery (1.51, 1.26 to 1.80), low one minute Apgar score (1.43, 1.01 to 2.03), macrosomia (1.70, 1.23 to 2.36), and infant born large for gestational age (1.57, 1.25 to 1.97). In studies with insulin use, when adjusted for confounders, the odds of having an infant large for gestational age (odds ratio 1.61, 1.09 to 2.37), or with respiratory distress syndrome (1.57, 1.19 to 2.08) or neonatal jaundice (1.28, 1.02 to 1.62), or requiring admission to the neonatal intensive care unit (2.29, 1.59 to 3.31), were higher in women with gestational diabetes mellitus than in those without diabetes. No clear evidence was found for differences in the odds of instrumental delivery, shoulder dystocia, postpartum haemorrhage, stillbirth, neonatal death, low five minute Apgar score, low birth weight, and small for gestational age between women with and without gestational diabetes mellitus after adjusting for confounders. Country status, adjustment for body mass index, and screening methods significantly contributed to heterogeneity between studies for several adverse outcomes of pregnancy. CONCLUSIONS When adjusted for confounders, gestational diabetes mellitus was significantly associated with pregnancy complications. The findings contribute to a more comprehensive understanding of the adverse outcomes of pregnancy related to gestational diabetes mellitus. Future primary studies should routinely consider adjusting for a more complete set of prognostic factors. REVIEW REGISTRATION PROSPERO CRD42021265837.

Curr Diabetes Rev 2022; 18:e021921191604. [PMID: 33605864 DOI: 10.2174/1573399817666210219124628] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Revised: 12/20/2020] [Accepted: 12/23/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Gestational Diabetes Mellitus (GDM) shares in part the pathogenic mechanisms of multiple genetic interactions. Some of the T2D susceptibility genes are encountered in association with GDM. OBJECTIVE We aimed to investigate GST T1, M1, and G972R IRS-I gene polymorphisms with the risk of developing GDM. METHODS In this randomized case-control study, pregnant women with GDM were genotyped by PCR analysis for glutathione s-transferase-T1, M1 variant polymorphisms. RFLP was done for the G972R IRS 1 gene. Their newborns were additionally assayed for the whole of the clinical, laboratory, and genetic aspects. RESULTS The T allele IRS-1rs1801278 TT genotype was more frequently detected in GDM mothers in comparison to healthy control ones [for TT homozygous variant; OR(CI 95%): 2.05(1.09-3.87, p: 0.025)]. Furthermore, GST T1 null was significantly presented in GDM mothers than those of control mothers [OR (CI95%: 0.29 (0.084-1.02), p:0.04]. Added to the significant correlation of glycemic indices to clinical parameters of infants born to GDM, the M1-null genotype of GST was significantly correlated (p<0.05) to abnormal values of respiratory rates and 1 minute-APGAR score noted for extra NICU care. CONCLUSION Our results suggested that GST T1null and IRS-1 TT genotypic variants were claimed for GDM development among Egyptian women with a possible impact on their newly born infants.

Abstract
OBJECTIVE We aimed to analyse the pre-analytical process and its effect of 50 g of oral glucose challenge test results for screening gestational diabetes mellitus. RESEARCH DESIGN AND METHODS The 50 g oral glucose challenge test was performed to 30 pregnant women, and the blood was collected as two samples for three tubes containing; serum separating jell (SSJ), sodium fluoride-potassium oxalate (NaF - KOx) and sodium citrate-containing tube. The first samples of the three tubes were centrifuged within 30 minutes, and second samples were centrifuged after 60 minutes and were analysed. One sample in SSJ tube and was analysed in the same day according to hospitals routine practice. The results were compared. RESULTS Among the 30 samples, the mean decrease in glucose levels was highest in the SSJ tube (0.38 mmol/L), followed by 0.16 mmol/L in Na citrate tube and 0.14 mmol/L in NaF-KOx tube. The hospital routine assessment with SSJ was 6.36 ± 1.90 mmol/L. The <30 and >60 minutes glucose results were 6.80 ± 1.88 mmol/L vs 6.42 ± 1.97 mmol/L for SSJ, 5.95 ± 1.60 mmol/L vs 5.78 ± 1.51 mmol/L for Na Citrate and 6.90 ± 1.86 mmol/L vs 6.75 ± 1.90 mmol/L for NaF-KOx mg/dL groups, respectively, and both the changes within time and the results between the tubes showed a statistically significant difference (P < .001). CONCLUSION In cases with longer assessment time and with different blood sample tubes, the clinician should also keep in mind that, especially with results under but close to the cut-off levels, an underdiagnosed gestational diabetes might be present.

Abstract
BACKGROUND Reference symphysis-fundal height (SFH) curves for pregnancies complicated by maternal hyperglycemia are not available. OBJECTIVE To build an SFH curve according to gestational age for pregnant women with hyperglycemia-type 2 diabetes (T2DM), gestational diabetes mellitus (GDM), or mild gestational hyperglycemia (MGH) and compare it with three other curves in use in Brazil. METHODS Prospective cohort study of 422 pregnant women with hyperglycemia attending the Perinatal Diabetes Research Center (PDRC) of Botucatu Medical School, São Paulo State University/UNESP. Between 13 and 41 weeks of pregnancy, 2470 SFH measurements were obtained (mean 5.85 per woman). For the assessment of glycemic control, 2074 glucose level measurements were taken and the glycemic mean (GM) at each gestational week was estimated. RESULTS GM was adequate (<120 mg/dL) in 94.9% and inadequate (≥120 mg/dL) in 5.1% of the cases. The equation applied for SFH prediction was expressed as SFH = 1.082 + 0.966∗week (r 2 = 84.6%). At visual analysis, P10 and P90 SFH measurements were higher in the study curve than in the three other curves. Statistical analysis confirmed that SFH median values in this study were higher than those in the reference curve of habitual risk pregnancies, especially after 19 weeks of pregnancy. CONCLUSION Taking into account that the maternal hyperglycemia was at strict control, our unedited results suggest that the current SFH curve can be a useful tool in prenatal care of T2DM, GDM, and MGH pregnant women.
