Objective We sought to assess the association of hemoglobin A1c (HbA1c) with adverse perinatal outcomes in obese women with gestational diabetes mellitus (GDM). Study design This was a secondary analysis of a multicenter randomized controlled trial assessing early (14-20 weeks) versus routine (24-28 weeks) screening for GDM in obese women. Women were included if they were diagnosed with GDM at either time during pregnancy and had a HbA1c result available. The primary exposure was HbA1c at 24 to 28 weeks. The primary outcome was a composite of macrosomia, primary cesarean, pregnancy-induced hypertension, shoulder dystocia, neonatal hypoglycemia, or hyperbilirubinemia. Receiver operating characteristics (ROC) curves were used to assess the association of HbA1c with the composite outcome. The Liu method was used to select an optimal HbA1c cutoff, and the incidence of the outcome compared. Results Of 125 women with GDM, 93 (74%) had a HbA1c at 24 to 28 weeks and 103 (82.4%) had a HbA1c at 14 to 20 weeks. Baseline characteristics were balanced between groups above and below the cutoff. The area under the ROC curve for HbA1c and its association with the adverse perinatal composite outcome was 0.6 (95% confidence interval [CI]: 0.5-0.7). The frequency of the primary outcome was similar among women with low and high HbA1c at 24 to 28 weeks (adjusted relative risk, 1.12, 95% CI: 0.97-1.29). Compared with women with a decreasing HbA1c during pregnancy, women with a stable or increasing HbA1c did not have a significant increase in the primary adverse perinatal composite outcome. However, the frequency of preterm delivery was higher among women with stable or increasing HbA1c compared with those with a decreasing HbA1c (26.1 vs. 6.7%, p = 0.03). Conclusion A single HbA1c in women with GDM is not associated with a composite perinatal adverse outcome, but a HbA1c that increases or remains stable between 14 to 20 and 24 to 28 weeks is associated with an increase in preterm delivery. Key points · A single HbA1c in GDM is not associated with a composite perinatal adverse outcome.. · HbA1c that increases or remains stable may be associated with an increase in preterm delivery.. · HbA1c at 24 to 28 weeks was not significantly associated with the adverse perinatal composite outcome..

BackgroundNeonatal hypoglycemia is a common disorder especially in at-risk infants and it can be associated with poor long-term neurological outcomes. Several therapeutic interventions are suggested, from the implementation of breastfeeding to the glucose intravenous administration. Oral dextrose gel massaged into the infant’s inner cheek is a recent treatment option of asymptomatic hypoglycemia, after which oral feeding is encouraged. This approach seems to reduce the admission of infants to neonatal intensive care unit (NICU) so favouring maternal bonding and breastfeeding success at discharge.MethodsIn our ward, we prospectively compared a group of near-term neonates, (Gr2,n = 308) at risk for hypoglycemia, treated with an innovative protocol based on the addition of 40% oral dextrose gel (Destrogel, Orsana®,Italy) administered by massaging gums and cheek with historical matching newborns (Gr1,n = 389) treated with a formerly used protocol, as control group. The primary outcome was occurrence of NICU admission and the requirement of intravenous glucose administration; while discharge with full breastfeeding was the secondary outcome.ResultsIn Gr1, 39/389 (10%) infants presented with asymptomatic hypoglycemia, 19/39 were transferred to the NICU, and 14/39 required intravenous glucose treatment. In Gr2, among the 30/308 infants with asymptomatic hypoglycemia managed according to the new protocol, 3/30 were transferred to the NICU and received intravenous glucose infusion. The mean duration of hospitalization respectively was 6.43 (± 6.36) and 3.73 ± 1.53 days (p p = 0.02). Considering Gr1 vs Gr2, the number of patients that were transferred to NICU was 19 (48.7%) vs 3 (10%) (p = 0.001) and the number of infants that needed intravenous glucose infusion was 14 (35.9%) vs 3 (10%) (p = 0.01), respectively.ConclusionsIn our population of near term infants, the introduction of 40% oral dextrose gel to the protocol, helped in the safe management of asymptomatic hypoglycemia and, at the same time, implemented breastfeeding.

Background Cat eye syndrome (CES) is a rare chromosomal disease, with estimated incidence of about 1 in 100,000 live newborns. The classic triad of iris coloboma, anorectal malformations, and auricular abnormalities is present in 40% of patients, and other congenital defects may also be observed. The typical associated cytogenetic anomaly relies on an extra chromosome, derived from an inverted duplication of short arm and proximal long arm of chromosome 22, resulting in partial trisomy or tetrasomy of such regions (inv dup 22pter-22q11.2). Case presentation We report on a full-term newborn, referred to us soon after birth. Physical examination showed facial dysmorphisms, including hypertelorism, down slanted palpebral fissures, and dysplastic ears with tragus hypoplasia and pre-auricular pit. Ophthalmologic evaluation and heart ultrasound identified left chorioretinal and iris coloboma and ostium secundum type atrial septal defect, respectively. Based on the suspicion of cat eye syndrome, a standard karyotype analysis was performed, and detected an extra small marker chromosome confirming the CES diagnosis. The chromosomal abnormality was then defined by array comparative genome hybridization (a-CGH, performed also in the parents), which identified the size of the rearrangement (3 Mb), and its de novo occurrence. Postnatally, our newborn presented with persistent hypoglycemia and cholestatic jaundice. Endocrine tests revealed congenital hypothyroidism, cortisol and growth hormone (GH) deficiencies, which were treated with replacement therapies (levotiroxine and hydrocortisone). Brain magnetic resonance imaging, later performed, showed aplasia of the anterior pituitary gland, agenesis of the stalk and ectopic neurohypophysis, confirming the congenital hypopituitarism diagnosis. She was discharged at 2 months of age, and included in a multidisciplinary follow-up. She currently is 7 months old and shows a severe global growth failure, and developmental delay. She started GH replacement treatment, and continues oral hydrocortisone, along with ursodeoxycholic acid and levothyroxine, allowing an adequate control of glycemic and thyroid profiles as well as of cholestasis. Conclusions CES phenotypic spectrum is wide and highly variable. Our report highlights how among the possible associated endocrine disorders, congenital hypopituitarism may occur, leading to persistent hypoglycemia and cholestasis. These patients should be promptly assessed for complete hormonal evaluations, in addition to major malformations and midline anomalies. Early recognition of such defects is necessary to decrease fatal events, as well as short and long-term related adverse outcomes.

OBJECTIVE To compare the rate of neonatal hypoglycemia among newborns delivered by individuals with Type 2 diabetes mellitus (T2DM) in two clinical scenarios: who attempted vaginal delivery vs. had a planned cesarean delivery (CD); who had intrapartum insulin infusion vs. who did not. METHODS This was a retrospective cohort study of individuals with insulin-treated T2DM who had non-anomalous singleton pregnancy and delivered at a single tertiary center (March 2012 and May 2018). Individuals with chronic renal failure, proliferative retinopathy, or major congenital anomalies were excluded. The primary outcome was neonatal hypoglycemia (blood glucose 24 h of age). Secondary outcomes included neonatal outcomes. Multivariable Poisson regression models with robust error variance were used to examine the association between groups and the primary outcome. Adjusted relative risk (aRR) and 95% confidence intervals (CI) were calculated. RESULTS Of 233 individuals with T2DM, 215 (92.2%) met the inclusion criteria, of whom 95 (44%) attempted vaginal delivery and 120 (56%) had a planned CD. Individuals who labored had a higher gestational age at delivery (36.6 vs. 35.8 weeks, p = .005), and higher blood glucose levels upon admission (125 vs 103, p

To evaluate birth outcomes in women with hypertensive disorders of pregnancy (HDP) and gestational diabetes mellitus (GDM), we used insurance data of Taiwan to evaluate 11 adverse neonatal outcomes of infants born to women with HDP (N = 7775) and with both HDP and GDM (HDP/GDM) (N = 1946), comparing to women with neither disorder (N = 19,442), matched by age. The impacts of preeclampsia/eclampsia were also evaluated. Results showed that Caesarean section delivery was near 1.7-fold greater in the HDP/GDM and HDP groups than in comparisons. The preterm delivery rates were more than threefold greater in HDP/GDM group and HDP group than in comparisons with adjusted odds ratios (aORs) of 4.84 (95% confidence interval (CI) 4.34–5.40) and 3.92 (95% CI 3.65–4.21), respectively, followed by jaundice (aORs 2.95 (95% CI 2.63–3.33) and 1.90 (95% CI 1.76–2.06)), and small gestation age (SGA) (aORs 6.57 (95% CI 5.56–7.75) and 5.81 (95% CI 5.15–6.55)). Incidence rates of birth trauma, patent ductus arteriosus, atrial septal defect, respiratory distress syndrome, and neonatal hypoglycemia were also higher in the HDP/GDM and HDP groups than in the comparison group. Most adverse outcomes increased further in women with preeclampsia or eclampsia. In conclusion, women with HDP are at elevated risks of adverse neonatal outcomes. Risks of most adverse outcomes increase further for women with both HDP and GDM. Preeclampsia or eclampsia may also contribute to these outcomes to higher risk levels. Every pregnant woman with these conditions deserves specialized prenatal care.

Background CHARGE syndrome (CS) is an autosomal dominant genetic condition whose recognition in the neonatal period is complicated by considerable phenotypic variability. Pediatric patients with genetic disorders have a known high incidence of hypoglycemia, due to many concurring factors. To date, neonatal hypoglycemia is a feature poorly explored in the literature associated with CS. This paper adds to the existing literature on hypoglycemia in CS and provides a brief review of the mechanisms through which CS, as well as the main genetic syndromes associated with neonatal hypoglycemia, may determine it. Case presentation The patient was a term newborn, first-born daughter to non-consanguineous parents. At birth, axial hypotonia with slight hypertonia of the limbs, and dysplastic auricles were noted. The incidental finding of asymptomatic hypoglycemia led to the initiation of glucose infusion on the II day of life, continued for a total of 8 days (maximum infusion rate: 8 mg/kg/min). In-depth endocrinological examinations showed poor cortisol response to the hypoglycemic stimulus, with normal GH values, thyroid function and ACTH. In view of the suspected hypoadrenalism, oral hydrocortisone therapy was initiated. Inappropriately low values of plasmatic and urinary ketones supported the hypothesis of concomitant transient hyperinsulinism, not requiring therapy. A brain MRI was performed, documenting thinning of the optic nerves, non-displayable olfactory bulbs and dysmorphic corpus callosum. An eye examination revealed bilateral chorioretinal coloboma. Temporal bone CT scan showed absence of the semicircular canals. The unexpected findings of coloboma and absence of semicircular canals led to the suspicion of CS, later confirmed by the molecular analysis of CHD7. Conclusions It seems important to consider CS in the differential diagnosis of persistent hypoglycemia in newborns with specific anomalies. At the same time, it is advisable to consider the risk of hypoglycemia in children with CS, as well as other genetic syndromes. Awareness of the many possible causes of hypoglycemia in newborns with genetic conditions may help steer the investigations, allowing for an appropriate and timely treatment.

Maternal diabetes mellitus in pregnancy is associated with impairments in memory functions of the offspring in childhood and adolescence but has not been studied in adulthood. The association of perinatal hypoglycemia with memory has not been studied in adulthood either. The combined sequelae of these two risk factors have not been directly compared. We studied general cognitive ability and memory functions in a prospective follow-up of a cohort born in 1971 to 1974. The sample included participants exposed to prenatal hyperglycemia (n = 24), perinatal hypoglycemia (n = 19), or both (n = 7). It also included controls with no early risks (n = 82). We assessed the participants' Intelligence quotient (IQ), working memory, and immediate and delayed recall of both verbal and visual material at the age of 40. We did not find significant differences in IQ or the memory tests between the groups. We did identify an interaction (p = 0.03) of the early risk with the type of digit span task: compared to the controls, the participants exposed to perinatal hypoglycemia had a larger difference between the forward digit span, a measure of attention, and the backward digit span, a measure of working memory processing (p = 0.022). The interaction remained significant when birth weight was controlled for (p = 0.026). Thus, in this small cohort, prenatal hyperglycemia, perinatal hypoglycemia, and their combination appeared relatively benign disorders. The association of these conditions with neurocognitive impairments in adulthood remains unconfirmed. The significance of the working memory difference needs to be verified with a larger sample.

Objectives Transient hyperinsulinism (THI) is a hypoglycemia disorder which resolves spontaneously within the first weeks or months of life. The pathomechanism of THI is not elucidated yet; however, it is known that perinatal stress predisposes for THI. We aimed to characterize the clinical phenotype and treatment of children with THI, and to identify options for improved management. Methods A retrospective analysis of 36 children with THI treated at the University Children’s Hospital Düsseldorf between 2007 and 2019 was performed. Results All children had risk factors for neonatal hypoglycemia or indicators of perinatal stress. Eighty three percent were diagnosed with hypoglycemia on day of life (DOL)1. None of the six diagnosed later had routine blood glucose screening and showed significantly lower blood glucose levels at the time of first blood glucose measurement compared to the children diagnosed on DOL1. Ninety seven percent of all children received intravenous glucose, 42% received continuous glucagon and 81% were started on diazoxide. Diazoxide withdrawal and subsequent fasting tests lacked standardization and were based on clinical experience. Three patients had a subsequent episode of hypoglycemia, after fasting studies only demonstrated “clinical” remission without proving the ability to ketogenesis. Conclusions Any kind of perinatal stress might pose a risk to develop THI, and postnatal monitoring for hypoglycemia still needs to be improved. Diazoxide is effective in children with THI; however, further studies are needed to guide the development of criteria and procedures for the initiation and discontinuation of treatment. Furthermore, establishing consensus diagnostic criteria/definitions for THI would improve comparability between studies.

We analyzed claims data from the Taiwan National Health Insurance database, which contains data of 23.5 million Taiwan residents. We included children born after January 1, 2000 who had received a diagnosis of autism spectrum disorders (ASD). Patients who were not diagnosed with ASD were included in the control group. The ASD prevalence was 517 in 62,051 (0.83%) children. Neonatal jaundice, hypoglycemia, intrauterine growth retardation (IUGR), and craniofacial anomalies (CFA) differed significantly between the ASD and control groups. After logistic regressive analysis, the adjusted odds ratios of IUGR, CFA, neonatal hypoglycemia, and neonatal jaundice were 8.58, 7.37, 3.83, and 1.32, respectively. Those insidiously perinatal risk factors, namely CFA, IUGR, neonatal hypoglycemia, and neonatal jaundice, could increase the risk of ASD.

OBJECTIVE The optimal method of monitoring glycemia in pregnant women with type 1 diabetes remains controversial. This study aimed to assess the predictive performance of HbA1c, continuous glucose monitoring (CGM) metrics, and alternative biochemical markers of glycemia to predict obstetric and neonatal outcomes. RESEARCH DESIGN AND METHODS One hundred fifty-seven women from the Continuous Glucose Monitoring in Women With Type 1 Diabetes in Pregnancy Trial (CONCEPTT) were included in this prespecified secondary analysis. HbA1c, CGM data, and alternative biochemical markers (glycated CD59, 1,5-anhydroglucitol, fructosamine, glycated albumin) were compared at ∼12, 24, and 34 weeks’ gestation using logistic regression and receiver operating characteristic (ROC) curves to predict pregnancy complications (preeclampsia, preterm delivery, large for gestational age, neonatal hypoglycemia, admission to neonatal intensive care unit). RESULTS HbA1c, CGM metrics, and alternative laboratory markers were all significantly associated with obstetric and neonatal outcomes at 24 weeks’ gestation. More outcomes were associated with CGM metrics during the first trimester and with laboratory markers (area under the ROC curve generally 140 mg/dL [>7.8 mmol/L]) were the most consistently predictive CGM metrics. HbA1c was also a consistent predictor of suboptimal pregnancy outcomes. Some alternative laboratory markers showed promise, but overall, they had lower predictive ability than HbA1c. CONCLUSIONS HbA1c is still an important biomarker for obstetric and neonatal outcomes in type 1 diabetes pregnancy. Alternative biochemical markers of glycemia and other CGM metrics did not substantially increase the prediction of pregnancy outcomes compared with widely available HbA1c and increasingly available CGM metrics (TIR and TAR).

Background Until now, diabetes during pregnancy has been associated with a high risk of maternal, fetal, and neonatal morbidities and mortalities. The main aim of this study was to evaluate the risk factors of hypoglycemia in infants of diabetic mothers (IDMs) and to study the relationship between umbilical cord (UC) C peptide levels and the risk of developing hypoglycemia. Material and methods UC blood C-peptide and serial serum blood glucose measurements were done for all included singleton newborns born to diabetic mothers during the study period. Maternal and neonatal data such as gestational age, maternal age, maternal weight, types of diabetics and its control, maternal glycated hemoglobin (HbA1C), birth weight, Apgar score, and neonatal complete blood picture were collected. Results In total, 83 IDMs met the inclusion criteria. Fifty-four (65.06%) developed hypoglycemia and 29 (34.94%) remained normoglycemic. However, there were no significant differences between hypoglycemic and normoglycemic IDMs in terms of types of maternal diabetics (P value = 0.41), its duration (P value = 0.43). The hypoglycemia peak occurred within the first 3 h of life, with 33.11 ± 8.84 mg/dl for the hypoglycemia group and 54.10 ± 6.66 mg/dl for the normoglycemic group (P value P-value P value = 0.005). Conclusion Poor diabetes control, especially in the last trimester, is associated with neonatal hypoglycemia. Increased UC C-peptide levels could be used as an early indicator for the risk of developing neonatal hypoglycemia and a predictor for babies need neonatal admission.

OBJECTIVES: This study was conducted in order to explore and analyze the status of gestational diabetes (GDM) amongst pregnant women in Dubai, United Arab Emirates (UAE); a country with high prevalence of diabetes. We aimed to describe GDM-associated risk factors and clinical outcomes of pregnant women and their neonates. Our objective was to contribute to the broader literature on reproductive health disparities and to inform efforts to improve GDM care at our region. METHODS: Chart review of case records were used to collect data on both maternal and neonatal parameters and outcomes during the specified study period from two main maternity hospitals in Dubai. RESULTS: UAE national women with GDM were more prone to be obese or overweight compared to non-UAE women (p

Introduction The aim of the present study was to identify possible associations of fetal heart rate (FHR) patterns during the last 2 hours of labor with fetal asphyxia expressed by umbilical artery acidemia at birth and with neonatal complications in a large obstetric cohort. Material and methods Cardiotocographic recordings from 4988 singleton term childbirths over 1 year were evaluated retrospectively and blinded to the pregnancy and neonatal outcomes in a university teaching hospital in Helsinki, Finland. Umbilical artery pH, base excess and pO(2), low Apgar scores at 5 minutes, need for intubation and resuscitation, early neonatal hypoglycemia, and neonatal encephalopathy were used as outcome variables. According to the severity of the neonatal complications at birth, the cohort was divided into three groups: no complications (Group 1), moderate complications (Group 2) and severe complications (Group 3). Results Of the 4988 deliveries, the ZigZag pattern (FHR baseline amplitude changes of >25 bpm with a duration of 2-30 minutes) occurred in 11.7%, late decelerations in 41.0%, bradycardia episodes in 52.9%, reduced variability in 36.7%, tachycardia episodes in 13.9% and uterine tachysystole in 4.6%. No case of saltatory pattern (baseline amplitude changes of >25 bpm with a duration of >30 minutes) was observed. The presence of the ZigZag pattern or late decelerations, or both, was associated with cord blood acidemia (odds ratio [OR] 3.3, 95% confidence interval [CI] 2.3-4.7) and severe neonatal complications (Group 3) (OR 3.3, 95% CI 2.4-4.9). In contrast, no significant associations existed between the other FHR patterns and severe neonatal complications. ZigZag pattern preceded late decelerations in 88.7% of the cases. A normal FHR preceded the ZigZag pattern in 90.4% of the cases, whereas after ZigZag episodes, a normal FHR pattern was observed in only 0.9%. Conclusions ZigZag pattern and late decelerations during the last 2 hours of labor are significantly associated with cord blood acidemia at birth and neonatal complications. The ZigZag pattern precedes late decelerations, and the fact that normal FHR pattern precedes the ZigZag pattern in the majority of the cases suggests that the ZigZag pattern is an early sign of fetal hypoxia, which emphasizes its clinical importance.

Neonatal hypoglycemia is a known side effect of antenatal betamethasone (BMZ) given for fetal maturation. We sought to investigate if delayed cord clamping (DCC) has an impact on neonatal hypoglycemia induced by antenatal late preterm BMZ administration.Retrospective cohort study (January 2019-May 2019) of pregnancies undergoing delivery at 34-0/7 to 36-6/7 weeks at a single center included in two groups: DCC + BMZ and BMZ-only (no DCC). The primary outcome was the occurrence of neonatal hypoglycemia at the first hour after delivery.A total of 62/188, 32.98% (DCC + BMZ group) and 45/100, 45% (DCC-only group) infants presented with hypoglycemia at 1-h after birth (adjustedIn our cohort, delayed cord clamping in infants receiving late preterm BMZ born between 35-0/7 and 36-6/7 weeks' gestation protects from early neonatal hypoglycemia.

OBJECTIVE To assess Neonatal Intensive Care Unit (NICU) admissions for hypoglycemia after the introduction of the Baby Friendly Hospital Initiative (BFHI), followed by implementation of American Academy of Pediatrics recommended hypoglycemia guidelines. STUDY DESIGN Retrospective review of NICU admissions for hypoglycemia. Eligible subjects were healthy infants >35 weeks gestation transferred to a NICU for hypoglycemia. Infants admitted with other pathologies were excluded. NICU admissions from 3 different 18-month epochs (1 = pre-BFHI; 2 = post-BFHI; 3 = post-BFHI+hypoglycemia guidelines) were compared. RESULTS After implementation of BFHI there was a statistically significant increase in admissions for hypoglycemia (Epoch 2 = 1.23% vs Epoch 1 = 0.55%, p

Background Congenital Hyperinsulinism typically occurs with a neonatal hypoglycemia but can appear even in childhood or in adolescence with different types of glucose metabolism derangements. Current diagnostic algorithms don’t take into account cases with a late presentation. Patients and methods Clinical and laboratory data of twenty-two subjects diagnosed at Federico II University of Naples have been described: patients have been divided according to the molecular defect into channel defects, metabolic defects and unidentified molecular defects. A particular focus has been made on three cases with a late presentation. Results and conclusions Late presentation cases may not be identified by previous diagnostic algorithms. Consequently, it seems appropriate to design a new flow-chart starting from the age of presentation, also considering that late presentation cases can show glucose metabolism derangements other than hypoglycaemic crises such as diabetes, glucose intolerance, postprandial hypoglycaemia and gestational diabetes.

Background The diagnosis of hypoglycemia and the use of diazoxide have risen in the last decade. Diazoxide is the only Food and Drug Agency-approved pharmacologic treatment for neonatal hypoglycemia caused by hyperinsulinism (HI). Recent publications have highlighted that diazoxide has serious adverse effects (AEs) such as pulmonary hypertension (2–3%) and neutropenia (15%). Despite its increasing use, there is little information regarding dosing of diazoxide and/or monitoring for AEs. Methods We convened a working group of pediatric endocrinologists who were members of the Drug and Therapeutics Committee of the Pediatric Endocrine Society (PES) to review the available literature. Our committee sent a survey to its PES members regarding the use of diazoxide in their endocrine practices. Our review of the results concluded that there was substantial heterogeneity in usage and monitoring for AEs for diazoxide among pediatric endocrinologists. Conclusions Based on our extensive literature review and on the lack of consensus regarding use of diazoxide noted in our PES survey, our group graded the evidence using the framework of the Grading of Recommendations, Assessment, Development and Evaluation Working Group, and has proposed expert consensus practice guidelines for the appropriate use of diazoxide in infants and children with HI. We summarized the information on AEs reported to date and have provided practical ideas for dosing and monitoring for AEs in infants treated with diazoxide.

Neonatal hypoglycemia is a common diagnosis for which management strategies vary. Our goal was to implement hypoglycemia algorithms (HGA) to streamline management of neonatal hypoglycemia within our hospital system and improve outcomes related to promoting the mother-infant dyad and decreasing hospital costs.A retrospective cohort study analyzed data on 4,666 asymptomatic infants at risk for hypoglycemia and born at two, large, community hospitals between 2010 and 2016. The first algorithm (HGA1) was created in 2012 and subsequently updated (HGA2) in 2014 to include the use of dextrose gel. Infants were separated into three groups by epoch: pre-HGA (2010-2011), HGA1 (2012-2013), and HGA2 (2014-2016). Outcomes between groups were then analyzed. Cost savings were calculated using linear regression.Compared with the pre-HGA group, the HGA1 group had decreased intravenous dextrose use (3.9 vs. 2.5%,By implementing HGA1 and providing resources to unify care for asymptomatic infants at risk for hypoglycemia, short-term outcomes in our hospital system improved. By updating HGA2 to include the use of dextrose gel, the advantages gained by HGA1 were maintained and further enhanced. Overall cost of care was reduced.

OBJECTIVE: To examine whether an insulin protocol for intrapartum glucose control among parturients with diabetes was associated with improved outcomes. METHODS: This is a retrospective cohort study of women with pregestational or gestational diabetes delivering a live-born neonate at Northwestern Memorial Hospital. Before 2011, women with diabetes were given intravenous insulin or glucose during labor at the discretion of the on-call endocrinologist. In 2011, a standardized protocol was designed to titrate insulin and glucose infusions. Outcomes were compared between two time periods: 1/2005–12/2010 (before implementation) and 1/2012–12/2017 (after implementation) with 2011 excluded to account for a phase-in period. Maternal outcomes included intrapartum hyperglycemia (blood glucose > 125 mg/dL) and hypoglycemia (blood glucose < 60 mg/dL). Neonatal outcomes included hypoglycemia (blood glucose < 50 mg/dL), intensive care admission, and intravenous dextrose therapy. T tests, Wilcoxon rank sum tests, and chi square tests were used for bivariable analyses. Linear and logistic multivariable regression were used to account for confounding factors. RESULTS: Of 3,689 women, 928 (25.2%) delivered prior to 2011. After protocol implementation, frequencies of both maternal intrapartum hyperglycemia (51.3% vs. 37.9%) and hypoglycemia decreased (6.1% vs. 2.5%), both p < 0.001; respective adjusted odds ratio [adj. OR] 0.64, 95% confidence interval [CI] 0.54–0.77 and 0.50, 95% CI 0.33–0.78. The frequency of neonatal hypoglycemia, however, increased (36.6% vs. 49.2%, p < 0.001; adj. OR 1.73, 95% CI 1.45–2.07). Admission to the neonatal intensive care unit and need for intravenous dextrose therapy were similar across time periods. CONCLUSIONS: A formal protocol to manage insulin and glucose infusions for parturients with diabetes was associated with improved intrapartum maternal glucose control, but an increased frequency of neonatal hypoglycemia.

The long-term consequences of transient neonatal hypoglycemia are sparsely studied. We performed a follow-up of a cohort of neonates with blood glucose recordings 2.5 mmol/L (> 45 mg/dL), compared with healthy siblings. Exclusion criteria were gestational age p = 0.03). In the sibling-paired analysis, the decrease in total motor score was highly significant, p = 0.009, driven by a decrease in fine motor score, p = 0.008. In the hypoglycemia group, adjusted analysis showed a lower fine motor function for boys, β = − 16.4, p = 0.048.Conclusion: Neonatal hypoglycemia treated with > 2.5 mmol/L was associated with lower fine motor scores within the normal range, particularly in boys. No associations with cognitive function or behavior were detected. What is Known:• Transient neonatal hypoglycemia is associated with acute neurologic dysfunction and long-term neurodevelopment impairment in 18 months of age. What is New:• Neonatal hypoglycemia treated with > 2.5 mmol/L is associated with lower fine motor function within the normal range, particularly in boys, but not to changes in cognitive function or behavior.

Purpose Neonatal hypoglycemic brain injury (NHBI) is being increasingly recognized as an important cause of drug resistant childhood epilepsy in low resource settings. We report the electro-clinical spectrum of children with epilepsy secondary to NHBI. Methods This was a retrospective study of children enrolled in the Epilepsy Clinic from January 2009 to August 2019. Data of children who had developed epilepsy after documented symptomatic neonatal hypoglycemia was collected. Details of clinical profile, seizure types, neurodevelopmental co-morbidities, EEG, neuroimaging findings and seizure outcomes were noted. Results One hundred and seventy children were enrolled. The mean age at seizure onset was 10.3 months (SD 0.5 months). The seizures types were epileptic spasms (76.5%), focal with visual auras (11.2%), bilateral tonic clonic (7.1%), myoclonic (3.5%) and atonic seizures (1.8%). The EEG findings included classical hypsarrhythmia (49.4%), hypsarrhythmia variant (27.1%), focal occipital or temporo-occipital spike wave discharges (10.6%), multifocal discharges (4.7%), diffuse slow spike and wave with bursts of fast rhythms (2.4%), continuous spike waves during sleep (1.2%) and normal EEG (4.7%). MRI showed gliosis with or without encephalomalacia in the occipital lobe with or without parietal lobe in 96.5% of the patients. Co-morbidities included global developmental delay (91.2%), cerebral palsy (48.7%), vision impairment (48.2%), microcephaly (38.2%), hearing impairment (19.4%), and behavioural problems (16.5%). Drug resistant childhood epilepsy was seen in 116 (68.2%) patients. Conclusions Our study highlights the varied electroclinical and radiological spectrum and the adverse epilepsy and neurodevelopmental outcomes associated with NHBI.

Objective To evaluate patterns of insulin secretion in pregnancy and analyze the association between insulin patterns and risks of gestational diabetes mellitus (GDM). Methods A prospective study was conducted to collect and analyze pregnant women's materials from January 2015 to December 2018. Pregnant women were grouped according to results of 75-g oral glucose tolerance test at 24-28 weeks of pregnancy: normal glucose tolerance (NGT) and GDM. Insulin secretion patterns were based on the time of peak(s) and shape of insulin secretion curve. The relationship between insulin secretion patterns and pregnant outcomes was analyzed. Results A total of 2432 pregnant women met the inclusion criteria during the study period. Among them, 737 (30.3%) women were grouped as GDM and 1695 (69.7%) as NGT. Type I insulin secretion represented the early phase of insulin secretion (peak time at 30 or 60 minutes), while type II represented the delayed peak of insulin secretion (peak time at 120 or 180 minutes). Logistic regression analysis showed that type II insulin secretion was a risk factor of pre-eclampsia, large-for-gestational-age, and neonatal hypoglycemia. Conclusion The delayed insulin peak is a useful marker for risk of GDM and adverse pregnant outcomes in women with GDM.

To evaluate the effects of updated gestational diabetes mellitus (GDM) screening and diagnostic criteria on selected perinatal outcomes in Queensland, Australia. This was a pre-post comparison study using perinatal data the year before (2014) and after (2016) the screening and diagnostic criteria for GDM was changed in Queensland, Australia. In 2015, Queensland adopted the one-step screening and diagnostic criteria based on the International Association of the Diabetes and Pregnancy Study Groups' recommendations. The data from 62,517 women in 2014 and 61,600 women in 2016 who gave birth from 24 weeks of gestation were analyzed in three groups in each year: women with GDM; women without diagnosed GDM; and total population. The outcome measures were gestational hypertension, cesarean birth, gestational age at delivery, birth weight, preterm delivery, large-for-gestational age (LGA) neonates, small-for-gestational-age (SGA) neonates, neonatal hypoglycemia, and respiratory distress. The diagnosis of GDM increased from 8.7% (n=5,462) to 11.9% (n=7,317). After changing the diagnostic criteria, the changes to outcomes, odds ratios (OR), and adjusted odds ratios (aOR) (95% CI) for outcomes with statistically significant differences for the total population were: gestational hypertension 4.6% vs 5.0%, OR 1.09 (1.03-1.15), aOR 1.07 (1.02-1.13); preterm birth 7.6% vs 8.0%, OR 1.05 (1.01-1.09), aOR 1.06 (1.02-1.10); neonatal hypoglycemia 5.3% vs 6.8%, OR 1.31 (1.25-1.37), aOR 1.32 (1.25-1.38); and respiratory distress 6.2% vs 6.0%, OR 0.96 (0.91-1.00), aOR 0.94 (0.89-0.99). There was no change to cesarean births or LGA or SGA neonates for women with or without diagnosed GDM or the total population. Except for a very small decrease in respiratory distress, changing the diagnostic criteria has resulted in more GDM diagnoses with no observed changes to measured perinatal outcomes for women with and without diagnosed GDM.

Background Gestational diabetes mellitus (GDM) is the most common metabolic disorder that can occur during pregnancy and is associated with a long-term risk of both maternal and neonatal comorbidities. This study aimed to investigate the association between echocardiographic epicardial adipose tissue (EAT) and the risk for GDM during the early second trimester of pregnancy. Method We recruited all singleton pregnancies between January 2014 and December 2018 at 16 weeks + 0 days to 19 weeks + 6 days. We then used generalized linear models to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for EAT as a potential predictor for GDM. Receiver-operating-characteristic (ROC) analysis was then conducted to investigate the discriminative capacity of any individual maternal factor for the prediction of GDM. Results In total, our study involved 314 pregnant women with GDM and 1832 pregnant women without GDM. Multivariate regression analysis revealed that EAT thickness (OR = 2.87; 95% CI: 2.49–3.31) was significantly associated with the presence of GDM (P < 0.001). Furthermore, EAT thickness was also significantly associated with a range of adverse outcomes in the GDM group, including large size for gestational age, neonatal hypoglycemia, admission to the neonatal intensive care unit, preterm delivery, and hyperbilirubinemia (P < 0.001). ROC analysis revealed that the area under the curve was 0.790 (95% CI: 0.768–0.812). When the cutoff value for EAT thickness was set to 5.49 mm, the sensitivity was 95.2% and the specificity was 50.5%. Conclusions Echocardiographic EAT thickness is positively and significantly associated with both the risk of GDM and adverse outcomes related to GDM. Echocardiographic EAT has the potential to predict GDM prior to actual clinical diagnosis.

Aims/Introduction This study aimed to investigate the effects of the introduction of the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria for diagnosing gestational diabetes mellitus (GDM) on maternal and neonatal outcomes in Japan. Materials and Methods This was a retrospective study carried out at a tertiary center in Japan. Previously in Japan, GDM was diagnosed if two or more of the following Japan Society of Obstetrics and Gynecology (JSOG) criteria were met: fasting plasma glucose ≥100 mg/dL, 1‐h value ≥180 mg/dL or 2‐h value ≥150 mg/dL on the 75‐g oral glucose tolerance. Since 2010, GDM has been diagnosed if one or more of the following IADPSG criteria are met: fasting plasma glucose ≥92 mg/dL, 1‐h value ≥180 mg/dL or 2‐h value ≥153 mg/dL on the 75‐g oral glucose tolerance. We compared the pregnancy outcomes of all pregnant women with singleton pregnancies after 22 weeks’ gestation at our hospital before (JSOG period) and after (IADPSG period) the IADPSG criteria were adopted. Results There were 3,912 women in the JSOG period and 4,772 in the IADPSG period. GDM prevalence increased from 2.9% in the JSOG period to 13% in the IADPSG period (P, After introduction of the International Association of Diabetes and Pregnancy Study Groups criteria to diagnose gestational diabetes mellitus, the rates of neonatal hypoglycemia and neonatal intensive care unit admission decreased. However, the introduction of the International Association of Diabetes and Pregnancy Study Groups criteria resulted in a significant increase in the gestational diabetes mellitus diagnosis rate and a fourfold increase in the number of pregnant women requiring therapeutic intervention. Further research is required to determine whether the effects are consistent with these changes and to evaluate the validity of these diagnostic criteria.

The objective of this study was to determine if the use of weight-based criteria to screen for asymptomatic hypoglycemia is consistent with using percentile curves to determine small and large for gestational age status. A retrospective chart review of 892 term infants in the normal nursery was performed. The degree of agreement in screening recommendations between weight-based criteria and the Lubchenco, Oken, and Olsen percentile curves was determined using Cohen’s κ and McNemar’s test. Agreement was lower between Lubchenco and Olsen or Oken (0.470, 0.509, respectively) than with weight-based criteria (Lubchenko = 0.532; Oken = 0.566; and Olsen = 0.582). Weight-based criteria recommended screening 12% and 7% fewer patients than Lubchenko and Oken, respectively ( P < .001), but was equally likely to screen infants as Olsen ( P = .579). Simple weight-based criteria for asymptomatic hypoglycemia screening can identify infants at risk for hypoglycemia in a manner consistent with current guidelines.

Background: Neonatal hypoglycemia is found in up to 15% of neonates and 50% of those with risk factors. Hypoglycemia can cause brain damage and increase risk of developmental delay. Nevertheless, the data regarding hypoglycemia prevention by oral sucrose are still limited. The present study aimed to investigate whether oral sucrose solution can prevent hypoglycemia in high-risk infants. Patients and Methods: Four hundred and twenty-five infants with high hypoglycemic risk were randomized into two groups (214 infants in the intervention and 211 infants in the control groups). The intervention group received one dose of 0.8 ml/kg of 24% oral sucrose solution followed by enteral feed and was compared to the control group receiving enteral feed alone. Glucose levels were evaluated by Dextrostrix. Results: There was no significant difference in antenatal and perinatal risk factors of neonatal hypoglycemia between groups. Glucose level on admission was 72.1±20.3 and 72.1±24.1 mg/dl in the intervention and control groups, respectively. Although no significant difference was recognized in terms of capillary blood glucose levels between groups, data analysis revealed that the glucose increase over time was significantly higher in the intervention group at 1 h (mean±SE=3.61±1.27 mg/dl; p

To estimate pregnancy complications in women newly diagnosed with gestational diabetes mellitus (GDM) according to the new International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria and verify the validity of introducing the IADPSG criteria in Japan. This retrospective study included data from women with singleton delivery at 22 weeks or later at a tertiary hospital during 2000-2009. We compared pregnancy outcomes between women who would now be diagnosed with GDM according to the IADPSG criteria but not by the old JSOG criteria (IGT group, n = 503) and women with normal glucose tolerance according to both the criteria (NGT group, n = 2,789). Multivariate analysis was performed and adjusted for background factors. Maternal age at delivery and pre-pregnancy BMI were significantly higher in the IGT group than in the NGT group, while gestational weeks at delivery did not differ between the groups. No difference was observed in the rates of GDM-related composite complications (defined as cases with at least one of the following: macrosomia, shoulder dystocia, neonatal hypoglycemia, neonatal hyperbilirubinemia, or neonatal respiratory distress syndrome) at 11.9% and 8.8% (adjusted odds ratio (OR) 1.30, 95% confidence interval (CI) 0.90-1.87, p = 0.16). Pregnancy outcomes did not differ significantly between the IGT and NGT groups, except for frequencies of total neonatal admissions at 10.5% and 7.1%, respectively (adjusted OR 1.55, 95% CI 1.12-2.13, p < 0.01).

Objective To describe the effects of the introduction of dextrose gel to the neonatal hypoglycemia (NH) protocol on exclusive breastfeeding rates at discharge and NICU admission rates among clinically well newborns born at 35 weeks gestation or greater who were at risk for NH in a Baby-Friendly hospital. Design Quasi-experimental, pre- and postintervention. Setting A suburban, Baby-Friendly hospital with approximately 2,000 births annually. Participants Clinically well newborns born at 35 weeks gestation or greater at risk for NH who were admitted to the mother–baby unit. Methods We compared 198 newborns at risk for NH born in the 6-month period before the introduction of dextrose gel (November 15, 2016, through May 14, 2017) versus 203 newborns born in the 6-month period after the introduction (May 15, 2017, through November 14, 2017). In the preintervention group, the NH protocol included blood glucose monitoring, prolonged skin-to-skin contact, feeding, and dextrose administered intravenously. In the postintervention group, oral dextrose gel was added to the NH protocol. Results We found no differences in maternal or newborn characteristics between the pre- and postintervention groups. Dextrose gel was given to 50 newborns (approximately 25%) of 203 in the postintervention group. The proportion of newborns who were exclusively breastfed at discharge was similar between groups (56.6% of 198 vs. 59.1% of 203, p = .62), as were the NICU admission rates for hypoglycemia (2.5% of 198 vs. 1.5% of 203, p = .50). Conclusions In a suburban Baby-Friendly hospital, introduction of dextrose gel into the NH protocol had no significant effect on exclusive breastfeeding at discharge or NICU admission rates.

The long-term consequences and need for therapy in children with short-chain acyl-CoA dehydrogenase deficiency (SCADD) or isobutyryl-CoA dehydrogenase deficiency (IBDD) identified via newborn screening (NBS) remains controversial. Initial clinical descriptions were severe; however, while most cases identified through NBS have remained asymptomatic, clinical concerns have been raised in these populations. It is not clear whether these children are asymptomatic because of the success of NBS, or because the normal clinical course of these disorders is relatively benign. To evaluate these possibilities in our program, we evaluated the clinical outcomes of children with SCADD or IBDD identified by the Georgia NBS compared to the health status of a healthy age-matched control group. We also assessed parental anxiety during a phone interview both subjectively and objectively using the Pediatric Inventory for Parents (PIP), a validated measure of illness-related parental stress. The general health of 52 SCADD and nine IBDD cases from 2007 to 2016 were compared to the general health of unaffected control children obtained through the Centers for Disease Control and Prevention (CDC) parent listserv. We also collected statements from parents who participated in a phone survey regarding events they experienced during and after their diagnostic process. Overall, the children with SCADD and IBDD had no major health problems. There was no significant difference in cognitive development (p = .207). We identified a slightly higher incidence of reported neonatal hypoglycemia in the SCADD group; two of these occurred in the context of maternal diabetes. All interviewed parents reported extreme anxiety during the diagnostic period and current feelings of uncertainty about their child's future. PIP scores for all six caregivers who responded to that portion of the survey were consistent with some degree of parental stress. The greatest reported stressor was the unknown long-term impact of the illness. All children with SCADD and IBDD had no significant long-term sequelae. The phone interviews revealed substantial parental anxiety about the identification and follow-up of SCADD and IBDD. Based on our findings, the anxiety parents experience may be unwarranted given that we see no disease-associated morbidity or mortality in these children. Consideration should be given to the removal of these conditions from NBS panels, or if that is not possible, clinicians could educate parents on the benign nature of these diagnoses and release them from follow-up without treatment.

To obtain precise findings from published studies about the efficacy and safety of glyburide versus subcutaneous insulin in patients with gestational diabetes mellitus (GDM). We searched PubMed, Cochrane Library, Web of Science, and Scopus, up to January 2019, for relevant studies that compared glyburide with subcutaneous insulin for patients with GDM. We extracted maternal and neonatal outcomes from included studies, performed meta-analysis, evaluated heterogeneity, assessed the risk of bias of included studies, and conducted subgroup and sensitivity analyses. A total of 24 studies (11 randomized controlled trials (RCTs) and 13 observational cohort studies) with a total of 24,517 women were included in the present study. The pooled estimate showed that glyburide significantly decreased the need for cesarean section (OR = 0.87, 95% CI [0.82, 0.92], p

The aim of this study was to determine the association between glucose control indices of parturient with type 1 diabetes (T1DM), treated with an insulin pump and utilizing continuous glucose monitoring (CGM), and clinically significant neonatal hypoglycemia. This was a retrospective cohort study which included 37 pregnant women with T1DM. All women were followed at a single tertiary center and had available CGM data. The association between maternal glucose indices before delivery and the risk for neonatal hypoglycemia requiring IV glucose (clinically significant hypoglycemia) was assessed using logistic regression. Mothers to neonates that experienced clinically significant hypoglycemia had a higher glucose standard deviation (SD) before delivery than did mothers to neonates who did not (25.5 ± 13 mg/dL vs. 14.7 ± 6.7 mg/dl respectively

Objective. In vivo study of glucose homeostasis in pregnancy suggests normal glucose levels are lower than current glycemic targets used in gestational diabetes. After the HAPO study results, our institution began using glycemic targets of fasting 85 mg/dL and 2-hour postprandial of 110 mg/dL. We reviewed our results.Methods. A retrospective cohort of GDM patients that delivered at KUMC from January 2007 to May 2017 was reviewed. All patients were diagnosed with the 2-step Carpenter-Coustan thresholds. High targets were compared with low targets. The primary outcome investigated wasbirthweight>90%(large for gestational age, LGA).Results. 604 patients were studied, and 34% were treated with low glycemic targets. Our unadjusted results showed that the low-target group had a lower incidence of LGA infants (24.0 vs. 31.8%), higher incidence of neonatal hypoglycemia (20.7 vs. 11.6%), and inductions (39.4 vs. 20.5%). After adjustment for demographic variables, only a higher risk of inductions remained (aOR 2.54 (1.44, 4.49)).Conclusion. Lower glycemic targets did not produce large reductions in fetal overgrowth, but they were associated with a higher rate of inductions. As there were no observed differences in maternal or neonatal outcomes otherwise, aiming for lower glycemic targets in GDM is likely not cost-effective.

Background and Objectives: Gestational diabetes mellitus (GDM) represents one of the most common complications during pregnancy, being associated with numerous maternal and neonatal complications. The study aimed to analyze maternal and neonatal complications associated with GDM. The risk factors of GDM and of the maternal and neonatal complications were studied in order to prevent their occurrence. Materials and Methods: The study included 97 women in the study, who underwent an oral glucose tolerance test (OGTT) between weeks 24–28 of pregnancy, consequently being divided into two groups: pregnant women with and without GDM. Statistical analysis was performed using the SPSS 26.0 software and MATLAB fitglm, the results being considered statistically significant if p &lt, 0.05. Results: We observed statistically significant differences between the group of women with and without GDM, regarding gestational hypertension (17.6% vs. 0%), preeclampsia (13.72% vs. 0%), and cesarean delivery (96.1% vs. 78,3%). Data on the newborn and neonatal complications: statistically significant differences were recorded between the two groups (GDM vs. no GDM) regarding the average weight at birth (3339.41 ± 658.12 g vs. 3122.83 ± 173.67 g), presence of large for gestational age (21.6% vs. 0%), macrosomia (13.7% vs. 0%), excessive fetal growth (35.3% vs. 0%), respiratory distress (31.4% vs. 0%), hospitalization for at least 24 h in the Neonatal Intensive Care Unit (9.80% vs. 0%), and APGAR score &lt, 7 both 1 and 5 min following birth (7.8% vs. 0%). Additionally, the frequency of neonatal hypoglycemia and hyperbilirubinemia was higher among newborns from mothers with GDM. Conclusions: The screening and diagnosis of GDM is vital, and appropriate management is required for the prevention of maternal and neonatal complications associated with GDM. It is also important to know the risk factors for GDM and attempt to prevent their appearance.

Aims We aimed to assess the comparative efficiency and safety of the use of glyburide, metformin, and insulin in gestational diabetes mellitus (GDM). Methods We searched for randomized controlled trials that compared glyburide, metformin, and insulin in GDM. Data regarding glycemic control and neonatal safety were collected and analyzed in pairwise and network meta-analyses. Results A total of 4533 individuals from 23 trials were included. Compared with glyburide, metformin reduced 2-h postprandial blood glucose (2HPG) to a greater extent (standard mean difference (SMD) 0.18; 95% credible interval (CI) 0.01, 0.34). There were significantly lower prevalence of neonatal hypoglycemia (risk difference (RD) − 0.07; 95%CI − 0.11, − 0.02) and preeclampsia (RD − 0.03; 95%CI − 0.06, 0) in the metformin group than in the insulin group. The metformin group had significantly lower birth weight (SMD − 0.17; 95%CI − 0.25, − 0.08) and maternal weight gain (SMD − 0.61; 95%CI − 0.86,− 0.35) compared with the insulin group. Network meta-analysis suggested that metformin had the highest probability of successfully controlling glycemia and preventing neonatal complications. Conclusions The present meta-analysis suggests that metformin may be as effective as insulin for glycemic control and is the most promising drug for the prevention of neonatal and maternal complications.

OBJECTIVE: To compare breastfeeding (BF) initiation among 317 women with chronic hypertension (CHTN) and 106 women with CHTN superimposed on pregestational diabetes (CHTN-DM) who intended exclusive or partial BF. METHODS: Retrospective cohort study of women who delivered at≥34 weeks of gestation. At discharge, exclusive BF was defined by direct BF or BF complemented with expressed breast milk (EBM) while partial BF was defined by formula supplementation. RESULTS: CHTN and CHTN-DM groups were similar in prior BF experience (42 vs 52%), intention to BF exclusively (89 vs 79%) and intention to partially BF (11 vs 21%). Women in the CHTN group were younger (31 vs 33y), more likely primiparous (44 vs 27%), and delivered vaginally (59 vs 36%) at term (85 vs 75%). Women in the CHTN-DM group had higher repeat cesarean rates (32 vs 18%), preterm birth (25 vs 15%), neonatal hypoglycemia (42 vs 14%) and NICU admission (38 vs 16%). At discharge, exclusive BF rates among CHTN was higher (48 vs 19%), while rates of partial BF (34 vs 44%) and FF (18 vs 37%) were lower than in the CHTN-DM group. BF initiation (exclusive plus partial BF) occurred in 82%of CHTN and in 63% of CHTN-DM. CONCLUSION: Although intention to BF was similar, BF initiation rates were higher for the CHTN compared to the CHTN-DM group. Exclusive BF was low in the CHTN and even lower in the CHTN-DM group signaling the need for targeted interventions if BF initiation rates are to be improved.

BackgroundRespiratory distress syndrome (RDS) is one of the leading causes of early neonatal morbidity and mortality in late preterm infants (LPIs) worldwide. This matched cohort study aimed to assess how the antenatal dexamethasone use affect the respiratory distress (RD) proportion in preterm newborns between 34 0/7 weeks and 36 6/7 weeks of gestation.MethodsThis was a prospective cohort study on 78 women with singleton pregnancy who were in threatened preterm birth and had not received prior dexamethasone, who were admitted between 34 0/7 weeks and 36 6/7 weeks at Hue University of Medicine and Pharmacy Hospital from June 2018 to May 2020. The matched control group without dexamethasone use included 78 pregnant women diagnosed with threatened late preterm births who were at similar gestational ages and estimated fetal weights as the treatment group. The treatment group received 6 mg intramuscular dexamethasone every 12 h for a total of 4 doses or until delivery. Primary outcome was the rate of neonatal RD. Secondary neonatal outcomes included the need for respiratory support, neonatal intensive care unit (NICU) admission, hypoglycemia, necrotizing enterocolitis, intraventricular hemorrhage, and neonatal death. Statistical analyses were performed by using SPSS software, version 26.0.ResultsThe proportion of RD in LPI was significantly lower in the treatment group than in the matched control group (10.3% vs. 23.1%, respectively), adjusted Odds Ratio [aOR] 0.29; 95% confidence interval [CI] 0.10 – 0.83 and p = 0.021. Neonatal hypoglycemia was more common in the dexamethasone group than in the matched group (25.6% vs. 12.8%, respectively; aOR, 2.59; 95% CI, 1.06 – 6.33; p = 0.037). There were no significant between-groups differences in the incidence of respiratory support, NICU admission or length of hospital stay.ConclusionsAdministration of antenatal dexamethasone to women at risk for late preterm birth could help to lower the proportion of respiratory distress in late preterm infants.

IntroductionThe incidence of gestational diabetes mellitus (GDM) is increasing in Australia, influenced by changed diagnostic criteria. We aimed to identify whether the diagnostic change was associated with improved outcomes and/or increased obstetric interventions using state-wide data in New South Wales (NSW), Australia.Research design and methodsPerinatal and hospital data were linked for singleton births, 33–41 weeks’ gestation, 2006–2015, NSW. An adjusted Poisson model was used to split pregnancies from 2011 onwards into those that would have been diagnosed under the old criteria (‘previous GDM’) and newly diagnosed cases (‘additional GDM’). We compared actual rates of total and early (ResultsGDM incidence more than doubled over the study period, with an inflection point observed at 2011. For those diagnosed with GDM since 2011, the actual incidence of interventions (planned births and cesareans) and macrosomia was consistent with scenario A, which meant higher intervention rates, but lower rates of macrosomia, than those with no GDM. Incidence of neonatal hypoglycemia was lower than scenario A and closer to the other scenarios. There was a reduction in perinatal deaths among those with GDM, lower than that predicted by all scenarios, indicating an improvement for all with GDM, not only women newly diagnosed. Incidence of maternal and neonatal morbidity indicators was within the confidence bounds for all three predicted scenarios.ConclusionsOur study suggests that the widely adopted new diagnostic criteria for GDM are associated with increased obstetric intervention rates and lower rates of macrosomic babies, but with no clear impacts on maternal or neonatal morbidity.

To compare the efficacy and safety of metformin, glyburide, and insulin in treating gestational diabetes mellitus (GDM), a meta-analysis of randomized controlled trials (RCTs) was conducted. PubMed, Embase, CINAHL, Web of Science, and Cochrane Library to November 13, 2018, were searched for RCT adjusted estimates of the efficacy and safety of metformin, glyburide, and insulin treatments in GDM patients. There were 41 studies involving 7703 GDM patients which were included in this meta-analysis; 12 primary outcomes and 24 secondary outcomes were detected and analyzed. Compared with metformin, insulin had a significant increase in the risk of preeclampsia (RR, 0.57; 95% CI, 0.45 to 0.72; P<0.001), NICU admission (RR, 0.75; 95% CI, 0.64 to 0.87; P<0.001), neonatal hypoglycemia (RR, 0.57; 95% CI, 0.49 to 0.66; P<0.001), and macrosomia (RR, 0.68; 95% CI, 0.55 to 0.86; P<0.05). To the outcomes of birth weight and gestational age at delivery, insulin had a significant increase when compared with metformin (MD, 114.48; 95% CI, 37.32 to 191.64; P<0.01; MD, 0.23; 95% CI, 0.12 to 0.34; P<0.001; respectively). Of the two groups between glyburide and metformin, metformin had lower gestational weight gain compared with glyburide (MD, 1.67; 95% CI, 0.26 to 3.07; P<0.05). Glyburide had a higher risk of neonatal hypoglycemia compared with insulin (RR, 1.76; 95% CI, 1.32 to 2.36; P<0.001). This meta-analysis found that metformin could be a safe and effective treatment for GDM. However, clinicians should pay attention on the long-term offspring outcomes of the relative data with GDM patients treated with metformin. Compared with insulin, glyburide had a higher increase of neonatal hypoglycemia. The use of glyburide in pregnancy for GDM women appears to be unclear.

Background Neonatal hypoglycemia is a common and treatable risk factor for neurological impairment. Real-time continuous glucose monitoring (RT-CGM) can show glucose concentration in real time. Using an RT-CGM alarm, physicians can be alerted and intervene in hypoglycemia. No reports, however, have evaluated the reliability of RT-CGM at low glucose levels in infants. This study therefore investigated the difference between blood glucose (BG) and RT-CGM sensor data at low glucose levels and assessed the optimum method of using a hypoglycemic alarm in infants. Methods We enrolled infants whose glycemic management was difficult. We calculated the mean absolute difference (MAD) and mean absolute relative difference (MARD) between BG and RT-CGM sensor data. We compared the MAD and MARD between the low BG fluctuation and high BG fluctuation groups. Results We used RT-CGM for 12 patients (29 times) and investigated 448 pairs of BG and RT-CGM sensor data. The MAD between these pairs was 9.3 ± 8.9 mg/dL, and the MARD was 11.5%. The MAD at low glucose was 7.7 ± 6.0 mg/dL, and the MARD was 16.2%. The MAD and MARD were 6.8 ± 5.4 mg/dL and 7.8% in the low fluctuation group and 10.1 ± 9.5 mg/dL and 12.7% in the high fluctuation group, respectively. Conclusions The difference between BG and RT-CGM sensor data changes with the degree of fluctuation in BG. When physicians set the hypoglycemic alarm, consideration of this difference and a change in the alarm setting according to the degree of fluctuation in BG may be useful.

Objective To determine whether basal insulin analogs reduce the rate of composite neonatal morbidity compared with neutral protamine Hagedorn (NPH) in women with type 2 diabetes mellitus (T2DM). Study Design This was a retrospective cohort study of women with T2DM and singleton pregnancy at a single tertiary center. Primary outcome was a composite neonatal morbidity of any of the following: shoulder dystocia, large for gestational age, neonatal intensive care unit admission, neonatal hypoglycemia, or respiratory distress syndrome. Secondary outcomes were rates of maternal hypoglycemic events, hypertensive disorders, preterm birth, and primary cesarean delivery. Adjusted relative risk (aRR) and 95% confidence intervals (CI) were calculated. Results Of 233 women with T2DM that met the inclusion criteria, 114 (49%) were treated with basal insulin analogs and 119 (51%) with NPH. The rate of composite neonatal morbidity was similar between groups (73 vs. 60%; aRR: 1.18; 95% CI: 0.92–1.51). There were no differences in the rates of maternal adverse outcomes between the groups. Basal insulin analog was associated with a lower rate of primary cesarean delivery as compared with NPH (21 vs. 36%; aRR: 0.44; 95% CI: 0.25–0.78). Conclusion Among pregnant women with T2DM managed with either basal or NPH insulin regimen, the rates of composite neonatal morbidity and maternal complications were similar.

Antenatal corticosteroids (ACS) are sporadically used in low and middle income countries (LMIC), although their use is considered by the World Health Organization (WHO) as essential for decreasing infant mortality. Presently the WHO recommends the use of ACS only when gestational age is known, delivery is imminent, and the delivery will be in a facility that can provide care for the mother and the infant. We review uncertainties about ACS in high income countries that are underappreciated for anticipating their effectiveness in LMIC. We discuss the implications of a large RCT that evaluated the use of ACS in LMIC and found no benefit for presumed preterm infants and increased mortality in larger infants. The treatment schedules for ACS have not been optimized and more is now known about how to improve treatment strategies to hopefully decrease risks such as neonatal hypoglycemia in LMIC. The benefits from ACS may depend on the patient populations and health care environment in which the therapy is used. Further trials are needed to evaluate the safety and efficacy of ACS in LMIC.

Gestational diabetes mellitus (GDM) is one of the most common complication of pregnancy and can lead to significant perinatal mortalities as well as long term risk of comorbidities for both mother and her offspring. This systematic review aimed to explore whether combined diet and exercise interventions are associated with improved glycemic control and/or improved maternal and newborn outcomes in women with GDM when compared to dietary interventions. A search on combined diet and exercise interventions during pregnancy in women with GDM was performed in 3 electronic databases: PubMed (NCBI), ScienceDierct, and the Cochrane Library. Evaluated outcomes were fasting blood glucose levels, postprandial blood glucose levels, glycated hemoglobin percentages, total weight gain during pregnancy, proportion of caesarean delivery, proportion of patients needing insulin, neonatal birth weight, proportion of macrosomia, neonatal hypoglycemia, and preterm birth. This systematic review identified eight randomized, controlled trials involving 592 pregnant women and 350 infants. The risk of bias of the included trials ranged from high to low. The combined diet and exercise interventions reduced fasting and postprandial blood glucose levels when compared to dietary interventions. No significant differences were reported in the selected trials regarding total weight gain during pregnancy, cesarean section, neonatal birth weight, macrosomia, neonatal hypoglycemia, and preterm birth between diet plus exercise and diet groups. The combination of diet and exercise interventions help to control postprandial blood glucose concentration in women diagnosed with GDM, but did not change either maternal or newborn outcomes.

Infants born to mothers with diabetes commonly experience asymptomatic hypoglycemia after birth. Continuous glucose monitors (CGM) can detect asymptomatic hypoglycemia in this population without the need for painful glucose checks.Infants born after 34 weeks of gestation to mothers with diabetes had a CGM placed after birth. One group of infants was remotely monitored in real-time by research staff during the hospitalization, whereas another group wore a blinded CGM. In both groups, hospital standard-of-care (SOC) glucose checks were performed. Clinical staff and families were blinded to CGM data. For CGM readings45 mg/dL, research staff requested a verification blood glucose (BG) using the point-of-care glucometer.Sixteen infants were studied; 4 with a blinded CGM and 12 with remote monitoring (RM). When there were confirmatory hospital glucometer readings, the sensitivity of the CGM to detect hypoglycemia was 86% and the specificity was 91%. The positive predictive value was 55% and the negative predictive value was 98%. In the full cohort, hypoglycemia (45 mg/dL) was confirmed in 12 of 16 infants with 30 events at12 hours of life (HOL), 3 events between 12 and 24 HOL, and 1 event at48 HOL. In the RM group, CGM detected hypoglycemia five times when the infant was not due for a BG check based on the SOC. Overall, the CGM detected five false-positive alerts and six true-positive alerts for hypoglycemia. Only one hypoglycemic episode was missed by CGM in the RM group. Barriers to recruitment included fear of pain with glucose checks, concerns with CGM use, satisfaction with the hospital SOC, personal reasons independent of the study, and lack of interest in participating in research.Although there were barriers to recruitment and retention in the study, we conclude that CGM can provide added benefit for detecting hypoglycemia when used early after birth.

The prevalence of gestational diabetes mellitus (GDM) is increasing worldwide. Ethnic differences in risk factors and perinatal outcomes are clinically important. Chinese women constitute approximately 10% of the world's population, and are an increasing migrant population, yet prevalence, risk factors, and outcomes of GDM in this population are insufficiently explored.A retrospective study of a large pregnancy dataset comparing GDM prevalence, risk factors, and perinatal outcomes between immigrant ethnic Chinese women and Australian-born Caucasian women was conducted using logistic regression.Overall, 73 517 births were extracted from the pregnancy databases of two of Australia's largest maternity services. Chinese women (n = 3419) had a 4-fold higher risk of GDM than Caucasians (n = 28 594) after adjusting for risk factors of GDM. A past history of GDM (adjusted odds ratio [aOR] 5.24; 95% confidence interval [95% CI] 2.91-9.42] was the main GDM risk factor in both groups. Other GDM risk factors varied between groups. Perinatal outcomes in Chinese women with and without GDM were similar, except for neonatal hypoglycemia (aOR 2.01; 95% CI 1.14-3.56]. Caucasian women with GDM had more adverse perinatal outcomes than women without GDM. After adjusting for confounders, Chinese women with GDM had a lower risk of labor induction, large-for-gestational-age babies, neonatal hypoglycemia, respiratory distress, and low Apgar scores than Caucasian women with GDM.Differences in prevalence, risk profile, and adverse outcomes in GDM were evident between ethnic Chinese and Caucasian women. A precision medicine approach to GDM may be warranted considering ethnicity and individual risk profiles rather than a one-size-fits-all approach.摘要: 背景 妊娠期糖尿病(gestational diabetes mellitus，GDM)的患病率在全球范围内不断上升。GDM危险因素以及围产期结局的种族差异具有重要的临床意义。中国女性约占世界人口的10%，并且其中移民人口越来越多，然而，目前尚未对这一人群中的GDM患病率、危险因素以及结局进行过充分的研究。 方法 这是一项利用大型妊娠数据集的回顾性研究，采用逻辑回归方法比较了华裔女性移民与澳大利亚出生的白人女性的GDM患病率、危险因素以及围产期结局的差异。 结果 从澳大利亚两个最大的产科服务机构的妊娠数据库中共提取了73 517名新生儿的相关数据。校正GDM的危险因素后，华裔女性(n=3419)患GDM的风险比白人女性(n=28 594)高4倍。在两组人群中既往GDM病史均为GDM的主要危险因素(校正后的比值比[aOR] 5.24；95%可信区间[95% CI] 2.91-9.42)。两组之间的其他GDM危险因素存在差异。除新生儿低血糖外(aOR 2.01；95% CI 1.14-3.56)，合并或者未合并GDM的华裔女性围产期结局相似。与未合并GDM的白人女性相比，合并GDM的白人女性的不良围产期结局更多。校正混杂因素后，与合并GDM的白人女性相比，合并GDM的华裔女性中引产、分娩大于胎龄儿、新生儿低血糖、呼吸窘迫和低Apgar评分的风险均较低。 结论 华裔女性与白人女性的GDM患病率、危险因素特征以及不良结局均存在明显差异。考虑到种族与个体危险特征均存在差异，对GDM患者需要采用精准的治疗方法，而不是一刀切的方法。.

It has been suggested that the risk of adverse perinatal outcomes in twin pregnancies is exacerbated by concomitant gestational diabetes mellitus (GDM). This study aimed to assess the risk incurred by twin pregnancy and by a diagnosis of GDM, separately, on the development of poor perinatal outcomes. A retrospective cohort study was conducted on all pregnant women at a tertiary center between 2016 and 2017. The impact of GDM and twin pregnancies on perinatal outcomes — birth weight above the 90th centile for gestational age, cesarean delivery, clinical neonatal hypoglycemia, and premature delivery (before 37 weeks’ gestation) — was assessed using univariate and multivariate analyses. Overall, 13,527 women were eligible for the study; 11,915 were uncomplicated singleton pregnancies; 1379 of these had GDM; 194 were twin pregnancies, and 39 of these had GDM. Univariate analyses showed that twin pregnancies were associated with a higher risk of all perinatal outcomes except macrosomia. In the multivariate analyses, twin pregnancy was a much higher predictor of cesarean delivery (OR 8.40, 95% CI [6.25, 11.49], p < .0001) and preterm birth (OR 58.82, 95% CI [31.25, 125], p < .0001) compared to GDM but GDM was a higher predictor of neonatal hypoglycemia (OR 4.87, 95% CI [3.74, 6.29], p < .0001). Twin pregnancy is more strongly associated with all adverse perinatal outcomes except macrosomia. GDM does not increase risk of adverse perinatal outcomes except for neonatal hypoglycemia.

Background: Weight gain during pregnancy reflects the mother’s nutritional status. However, it may be affected by nutritional therapy and exercise interventions used to control blood sugar in gestational diabetes mellitus (GDM). This study aimed to evaluate weight gain during gestation and pregnancy outcomes among women with GDM. Methods: A retrospective study involving 1523 women with GDM was conducted between July 2013 and July 2016. Demographic data, gestational weight gain (GWG), blood glucose, glycated-hemoglobin level, and maternal and fetal outcomes were extracted from medical records. Relationships between GWG and pregnancy outcomes were investigated using multivariate logistic regression. Results: In total, 451 (29.6%) women showed insufficient GWG and 484 (31.8%) showed excessive GWG. Excessive GWG was independently associated with macrosomia (adjusted odds ratio [aOR] 2.20, 95% confidence interval [CI] 1.50–3.52, P < 0.001), large for gestational age (aOR 2.06, 95% CI 1.44–2.93, P < 0.001), small for gestational age (aOR 0.49, 95% CI 0.25–0.97, P= 0.040), neonatal hypoglycemia (aOR 3.80, 95% CI 1.20–12.00, P= 0.023), preterm birth (aOR 0.45, 95% CI 0.21–0.96, P= 0.040), and cesarean delivery (aOR 1.45, 95% CI 1.13–1.87, P= 0.004). Insufficient GWG increased the incidence of preterm birth (aOR 3.53, 95% CI 1.96–6.37, P < 0.001). Conclusions: Both excessive and insufficient weight gain require attention in women with GDM. Nutritional therapy and exercise interventions to control blood glucose should also be used to control reasonable weight gain during pregnancy to decrease adverse pregnancy outcomes.

Evaluate the safety and efficacy of a subcutaneous insulin (SC-I) versus intravenous insulin (IV-I) protocol for optimizing maternal blood glucose levels (BGLs) post-betamethasone administration.Randomized controlled in-patient pilot study in pregnant women with diabetes, excluding type 1 diabetes, receiving betamethasone ≥24 weeks' gestation. Interventions were stratified SC-I and IV-I protocols, titrated to hourly BGLs (IV-I) or predicted maternal hyperglycemia and 2-4 hourly BGLs (SC-I). Primary outcome was percentage at-target BGL 4.0-8.0 mmol/L over 48 h post-betamethasone. Secondary outcomes were rates of maternal hyperglycemia (8.0 mmol/L), hypoglycemia (4.0 mmol/L) and neonatal hypoglycemia (≤2.5 mmol/L).19 women (3 with type 2 diabetes [T2DM], 4 with gestational diabetes [GDM]-diet, 12 GDM-insulin) were randomized to a SC-I (A SC-I or IV-I protocol controls maternal BGLs following betamethasone, but SC-I appears safe and minimizes labor intensive IV-I in GDM. An adequately powered RCT to assess superiority of SC-I is planned.

Aim In 2010, the Japan Society of Obstetrics and Gynecology (JSOG) changed the diagnostic criteria for gestational diabetes mellitus (GDM) to follow the International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria. As a result, many pregnant women with mildly impaired glucose tolerance (IGT) were newly diagnosed with GDM. This study aimed to verify the effects of interventions in pregnant women with mild IGT who were newly diagnosed with GDM based on the present JSOG criteria. Methods We defined mild IGT as a degree of IGT that would be diagnosed as GDM according to the present but not the previous JSOG criteria. We compared pregnancy and delivery outcomes in women with mild IGT who delivered a singleton at 22 weeks of gestation or later, between 2000 and 2009 (untreated group, n = 503) versus between 2011 and 2017 (treated group, n = 781). Results The incidence of GDM-related composite complications such as macrosomia, shoulder dystocia, neonatal hypoglycemia, neonatal hyperbilirubinemia, and neonatal respiratory distress syndrome was comparable in the untreated and treated groups (10.1% vs. 11.9%, p = 0.11). The pregnancy outcomes were also comparable, except for infant birth weights, which were lower in the treated group than in the untreated group (3014 g vs. 3094 g; p = 0.02). Conclusions Pregnancy outcomes were not affected by the interventions in pregnant women with mild IGT.

The worldwide rates of obesity have increased significantly in recent decades. In the United States, more than 50% of pregnant women are overweight or obese. Obese gravid women are more prone to adverse pregnancy outcomes, including gestational diabetes, hypertensive disorders, and cardiovascular diseases. The adverse outcomes extend beyond the pregnant obese woman; offspring of obese women are themselves at increased risk of prematurity, fetal death, injury during birth, and transient respiratory problems and metabolic effects (ie, neonatal hypoglycemia). Furthermore, maternal obesity can predispose their offspring to long-term health problems, potentially generating an intergenerational cycle of obesity and insulin resistance.
