Aims: To examine health behaviours and risk factors in women with pre‐existing diabetes or previous gestational diabetes mellitus who are planning pregnancy. Methods: Health behaviour, risk factor and demographic data obtained from a digital pregnancy planning advisory tool (Tommy's charity UK) were analysed. Descriptive statistical analysis was performed, stratified by diabetes type. Results: Data from 84,359 women, including 668 with type 1 diabetes, 707 with type 2 diabetes and 1785 with previous gestational diabetes obtained over a 12‐month period (September 2019–September 2020) were analysed. 65%, 95%CI (61,68%) of women with type 2 diabetes and 46%, 95%CI (43,48%) with previous gestational diabetes were obese (BMI ≥30 kg/m2), compared with 26%, 95%CI (26,26%) without diabetes. Use of folic acid supplements was low; 41%, 95%CI (40,41%) of women without diabetes and 42%, 95%CI (40,45%) with previous gestational diabetes reported taking folic acid (any dose) while 47%, 95%CI (43.50%) women with type 1 diabetes and 44%, 95%CI (40,47%) women with type 2 diabetes respectively reported taking the recommended dose (5 mg). More women with type 1 diabetes and type 2 diabetes reported smoking (20%, 95%CI [17,23%] and 23%, 95%CI [20,26%] respectively) and taking illicit/recreational drugs (7%, 95%CI [6,10%] and 9%, 95% CI [7,11%]) compared to women without diabetes (smoking 17%, 95% CI [16,17%], drug use 5%, 95%CI [5,5%]). Alcohol consumption, low levels of physical activity and of fruit and vegetable intake were also evident. Conclusions: This study highlights the potential of online pregnancy planning advisory tools to reach high‐risk women and emphasises the need to improve pre‐pregnancy care for women with pre‐existing diabetes and previous gestational diabetes, many of whom are actively seeking advice. It is also the first to describe pre‐pregnancy health behaviours in women with previous gestational diabetes. [ABSTRACT FROM AUTHOR]

Background: Offspring of women with type 1 diabetes are at increased risk of fetal growth patterns which are associated with perinatal morbidity. Our aim was to compare rates of large- and small-for-gestational age (LGA; SGA) defined according to different criteria, using data from the Continuous Glucose Monitoring in Type 1 Diabetes Pregnancy Trial (CONCEPTT). Methods: This was a pre-specified analysis of CONCEPTT involving 225 pregnant women and liveborn infants from 31 international centres (ClinicalTrials.gov NCT01788527; registered 11/2/2013). Infants were weighed immediately at birth and GROW, INTERGROWTH and WHO centiles were calculated. Relative risk ratios, sensitivity and specificity were used to assess the different growth standards with respect to perinatal outcomes, including neonatal hypoglycaemia, hyperbilirubinaemia, respiratory distress, neonatal intensive care unit (NICU) admission and a composite neonatal outcome. Results: Accelerated fetal growth was common, with mean birthweight percentiles of 82.1, 85.7 and 63.9 and LGA rates of 62, 67 and 30% using GROW, INTERGROWTH and WHO standards respectively. Corresponding rates of SGA were 2.2, 1.3 and 8.9% respectively. LGA defined according to GROW centiles showed stronger associations with preterm delivery, neonatal hypoglycaemia, hyperbilirubinaemia and NICU admission. Infants born > 97.7th centile were at highest risk of complications. SGA defined according to INTERGROWTH centiles showed slightly stronger associations with perinatal outcomes. Conclusions: GROW and INTERGROWTH standards performed similarly and identified similar numbers of neonates with LGA and SGA. GROW-defined LGA and INTERGROWTH-defined SGA had slightly stronger associations with neonatal complications. WHO standards underestimated size in preterm infants and are less applicable for use in type 1 diabetes. Trial registration: This trial is registered with ClinicalTrials.gov. number NCT01788527. Trial registered 11/2/2013.

Women with previous gestational diabetes mellitus (post-GDM) have an increased risk of cardiometabolic diseases including type 2 diabetes (T2D). Current diabetes screening is based on the oral glucose tolerance test without nutritional assessments, even though unhealthy dietary patterns were found to expedite disease progression in women post-GDM. While a healthful dietary pattern reduces T2D risk, limited data support a dietary pattern tailored to the Asian population, especially in the Malaysian context. Metabolomic profiles associated with dietary patterns in this population are also lacking. The proposed study aims to investigate both components of dietary patterns and metabolomic profile, known as nutritype signatures, and their association with T2D in women post-GDM. The comparative cross-sectional study will involve a minimum of 126 Malaysian women post-GDM aged 18–49 years. Dietary patterns will be analysed using principal component analysis. Plasma and urinary metabolites will be quantified using one-dimensional proton nuclear magnetic resonance (
1 H NMR) spectroscopy. The aim of the study is identifying the nutritype signatures associated with T2D. The findings will support the development of early prevention measures against T2D in women post-GDM. [ABSTRACT FROM AUTHOR]- Published

Background: Process evaluations of randomised controlled trials (RCTs) can provide insight and inform us on the intervention implementation, the causal mechanisms and the contextual factors. This will inform about interventions' success or failure due to their implementation or the interventions themselves. We aim to consolidate the methodology from previous process evaluations of complex interventions upon their findings on facilitators and barriers to address the prevention of type 2 diabetes mellitus among women with gestational diabetes mellitus (GDM). Methods: Comprehensive search will be conducted on electronic databases and reference lists of recent reviews for RCTs of complex interventions which address process evaluations of diabetes prevention intervention (DPI) for women with GDM in healthcare settings. There is no restriction on the language of the papers and year of publication until December 2020. Data from each study will be extracted by two reviewers independently using standardised forms. Data extracted include descriptive items on the study design and the outcomes of process evaluations from the three dimensions: (1) implementation; (2) mechanism of impact and (3) context. The quality of the studies will be assessed using mixed methods appraisal tool which is designed for the appraisal of mixed studies in systematic reviews. A narrative and framework analysis of the findings will be presented to inform the contents of a new DPI for women with GDM. Discussion: The findings from this process evaluation findings are valuable in determining whether a complex intervention should be scaled up or modified for other contexts in future plan. It will give deeper understanding of potential challenges and solutions to aid in the implementation of effective DPIs for GDM in Malaysia. [ABSTRACT FROM AUTHOR]

Bacon, Siobhan, Burger, Dylan, Tailor, Mayur, Sanchez, J. Johanna, Tomlinson, George, Murphy, Helen R., and Feig, Denice S.
- Abstract
Aims/hypothesis: Maternal hyperglycaemia alone does not explain the incidence of large offspring amongst women with type 1 diabetes. The objective of the study was to determine if there is an association between placental function, as measured by angiogenic factors, and offspring birthweight z score in women with type 1 diabetes. Methods: This cohort study included samples from 157 Continuous Glucose Monitoring in Pregnant Women with Type 1 Diabetes (CONCEPTT) trial participants. Correlations were estimated between birthweight z score and placental growth factor (PlGF) and soluble fms-like tyrosine kinase (sFlt-1) levels measured at baseline and at 24 and 34 weeks of gestation. Linear regression was used to assess the relationship between birthweight z score and placental health, as measured by PlGF and sFlt-1/PlGF ratio, stratified by glycaemic status (continuous glucose monitoring and HbA
1c measures) and adjusted for potential confounders of maternal BMI, smoking and weight gain. Higher PlGF levels and lower sFlt-1/PlGF ratios represent healthy placentas, while lower PlGF levels and higher sFlt-1/PlGF ratios represent unhealthy placentas. Results: Among CONCEPTT participants, the slopes relating PlGF levels to birthweight z scores differed according to maternal glycaemia at 34 weeks of gestation (p = 0.003). With optimal maternal glycaemia (HbA1c < 48 mmol/mol [6.5%]/ or continuous glucose monitoring time above range ≤ 30%), birthweight z scores were reduced towards zero (normal weight) with increasing PlGF values (representing a healthy placenta), and increased with decreasing PlGF values. With suboptimal glycaemic status (HbA1c ≥ 48 mmol/mol [6.5%] or time above range > 30%), increasing PlGF values were associated with heavier infants. Those with a healthy placenta (PlGF > 100) and suboptimal glycaemic control had a higher mean z score (2.45) than those with an unhealthy placenta (mean z score = 1.86). Similar relationships were seen when using sFlt-1/PlGF ratio as a marker for a healthy vs unhealthy placenta. Conclusions/interpretation: In women with type 1 diabetes, infant birthweight is influenced by both glycaemic status and placental function. In women with suboptimal glycaemia, infant birthweight was heavier when placentas were healthy. Suboptimal placental function should be considered in the setting of suboptimal glycaemia and apparently 'normal' birthweight. [ABSTRACT FROM AUTHOR]- Published

In recent years, continuous glucose monitoring (CGM) has become increasingly available with the introduction of devices that are specifically approved for use during pregnancy. Evidence in the form of randomized-controlled trials and cohort studies continues to build support for the use of CGM during pregnancy to improve measures of maternal glycemia as well as obstetric and neonatal outcomes. Based on data from the CGM in pregnant women with type 1 diabetes (CONCEPTT) trial alongside a Swedish cohort study of real-world outcomes of pregnant women with type 1 diabetes, the UK National Institute for Health and Clinical Excellence (NICE) guidelines now recommend that real-time CGM be offered to all pregnant women with type 1 diabetes. Based on these guidelines, all pregnant individuals in the United Kingdom with type 1 diabetes will receive government-funded real-time CGM for a 12-month duration. These guidelines are a game-changer and will continue to facilitate more widespread access to CGM use in the United Kingdom and beyond. This review describes the role of CGM in the management of diabetes in pregnancy, discusses contemporary maternal glucose levels and their relationship with outcomes in diabetes pregnancies, and examines the high-quality, randomized-controlled trial and the real-world clinical data evaluating the impact of CGM use.

Yamamoto, Jennifer M., Benham, Jamie L., Dewey, Deborah, Sanchez, J. Johanna, Murphy, Helen R., Feig, Denice S., and Donovan, Lois E.
- Abstract
Aims/hypothesis: We performed a systematic review and meta-analysis to determine whether exposure to maternal pre-existing diabetes in pregnancy is associated with neurocognitive or behavioural outcomes in offspring. Methods: We searched MEDLINE, EMBASE, PsychINFO, the Cochrane Database of Systematic Reviews and Scopus for studies that examined any neurocognitive or behavioural outcomes in offspring of mothers with pre-existing diabetes in pregnancy in accordance with a published protocol (PROSPERO CRD42018109038). Title and abstract review, full-text review and data extraction were performed independently and in duplicate. Risk of bias was assessed using the Newcastle–Ottawa scale. Meta-analyses of summary measures were performed using random-effects models. Results: Nineteen articles including at least 18,681 exposed and 2,856,688 control participants were identified for inclusion. Exposure to maternal pre-existing diabetes in pregnancy was associated with a lower pooled intelligence quotient in the offspring (pooled weighted mean difference −3.07 [95% CI −4.59, −1.55]; I
2 = 0%) and an increased risk of autism spectrum disorders (effect estimate 1.98 [95% CI 1.46, 2.68]; I2 = 0%). There was also an increased risk of attention deficit/hyperactivity disorder (pooled HR 1.36 [95% CI 1.19, 1.55]; I2 = 0%), though this was based on only two studies. Although most studies were found to be high quality in terms of participant selection, in many studies, comparability of cohorts and adequacy of follow-up were sources of bias. Conclusions/interpretation: There is evidence to suggest that in utero exposure to maternal pre-existing diabetes is associated with some adverse neurocognitive and behavioural outcomes. It remains unclear what the role of perinatal factors is and the degree to which other environmental factors contribute to these findings. [ABSTRACT FROM AUTHOR]- Published

Piper, Leanne K., Stewart, Zoe, and Murphy, Helen R.
- Abstract
Gestational diabetes mellitus (GDM) is defined as hyperglycaemia that is diagnosed for the first time in the second or third trimester of pregnancy. It occurs in one in seven pregnancies worldwide and is associated with increased risk of adverse perinatal outcome, in particular, infant birth weight that is large for gestational age, increased infant adiposity, preeclampsia and preterm delivery, and increased delivery by caesarean section. This review focuses on the controversy regarding screening and diagnosis of GDM following development of the International Association of Diabetes and Pregnancy Study Groups (IADPSG) guidelines and the National Institute of Clinical Excellence (NICE) 2015 guidelines. It reviews the most recent research in to diet and exercise modification in prevention and management of GDM, pharmacological management and post-partum management to delay and/or prevent progression to type 2 diabetes.

Background: Women with type 1 diabetes strive for optimal glycemic control before and during pregnancy to avoid adverse obstetric and perinatal outcomes. For most women, optimal glycemic control is challenging to achieve and maintain. The aim of this study is to determine whether the use of real-time continuous glucose monitoring (RT-CGM) will improve glycemic control in women with type 1 diabetes who are pregnant or planning pregnancy.Methods/design: A multi-center, open label, randomized, controlled trial of women with type 1 diabetes who are either planning pregnancy with an HbA1c of 7.0 % to ≤10.0 % (53 to ≤ 86 mmol/mol) or are in early pregnancy (<13 weeks 6 days) with an HbA1c of 6.5 % to ≤10.0 % (48 to ≤ 86 mmol/mol). Participants will be randomized to either RT-CGM alongside conventional intermittent home glucose monitoring (HGM), or HGM alone. Eligible women will wear a CGM which does not display the glucose result for 6 days during the run-in phase. To be eligible for randomization, a minimum of 4 HGM measurements per day and a minimum of 96 hours total with 24 hours overnight (11 pm-7 am) of CGM glucose values are required. Those meeting these criteria are randomized to RT- CGM or HGM. A total of 324 women will be recruited (110 planning pregnancy, 214 pregnant). This takes into account 15 and 20 % attrition rates for the planning pregnancy and pregnant cohorts and will detect a clinically relevant 0.5 % difference between groups at 90 % power with 5 % significance. Randomization will stratify for type of insulin treatment (pump or multiple daily injections) and baseline HbA1c. Analyses will be performed according to intention to treat. The primary outcome is the change in glycemic control as measured by HbA1c from baseline to 24 weeks or conception in women planning pregnancy, and from baseline to 34 weeks gestation during pregnancy. Secondary outcomes include maternal hypoglycemia, CGM time in, above and below target (3.5-7.8 mmol/l), glucose variability measures, maternal and neonatal outcomes.Discussion: This will be the first international multicenter randomized controlled trial to evaluate the impact of RT- CGM before and during pregnancy in women with type 1 diabetes.Trial Registration: ClinicalTrials.gov Identifier: NCT01788527 Registration Date: December 19, 2012.

Objective: To determine whether fetal overgrowth precedes the diagnosis of gestational diabetes mellitus (GDM) and to quantify the interrelationships among fetal overgrowth, GDM, and maternal obesity.Research Design and Methods: We conducted a prospective cohort study of unselected nulliparous women and performed ultrasonic measurement of the fetal abdominal circumference (AC) and head circumference (HC) at 20 and 28 weeks of gestational age (wkGA). Exposures were diagnosis of GDM ≥28 wkGA and maternal obesity. The risk of AC >90th and HC-to-AC ratio <10th percentile was modeled using log-binomial regression, adjusted for maternal characteristics.Results: Of 4,069 women, 171 (4.2%) were diagnosed with GDM at ≥28 wkGA. There was no association between fetal biometry at 20 wkGA and subsequent maternal diagnosis of GDM. However, at 28 wkGA, there was an increased risk of AC >90th percentile (adjusted relative risk 2.05 [95% CI 1.37-3.07]) and HC-to-AC ratio <10th percentile (1.97 [1.30-2.99]). Maternal obesity showed similar associations at 28 wkGA (2.04 [1.62-2.56] and 1.46 [1.12-1.90], respectively). The combination of GDM and obesity was associated with an approximately fivefold risk of AC >90th (4.52 [2.98-6.85]) and approximately threefold risk of HC-to-AC ratio <10th percentile (2.80 [1.64-4.78]) at 28 wkGA. Fetal AC >90th percentile at 28 weeks was associated with an approximately fourfold risk of being large for gestational age at birth.Conclusions: Diagnosis of GDM is preceded by excessive growth of the fetal AC between 20 and 28 wkGA, and its effects on fetal growth are additive with the effects of maternal obesity.

OBJECTIVE Continuous glucose monitoring (CGM) is increasingly used to assess glucose control in diabetes. The objective was to examine how analysis of glucose data might improve our understanding of the role temporal glucose variation has on large-for-gestational-age (LGA) infants born to women with diabetes. RESEARCH DESIGN AND METHODS Functional data analysis (FDA) was applied to 1.68 million glucose measurements from 759 measurement episodes, obtained from two previously published randomized controlled trials of CGM in pregnant women with diabetes. A total of 117 women with type 1 diabetes (n = 89) and type 2 diabetes (n = 28) who used repeated CGM during pregnancy were recruited from secondary care multidisci-plinary obstetric clinics for diabetes in the U.K. and Denmark. LGA was defined as birth weight S90th percentile adjusted for sex and gestational age. RESULTS A total of 54 of 117 (46%) women developed LGA. LGA was associated with lower mean glucose (7.0 vs. 7.1 mmol/L; P < 0.01) in trimester 1, with higher mean glucose in trimester 2 (7.0 vs. 6.7 mmol/L; P < 0.001) and trimester 3 (6.5 vs. 6.4 mmol/L; P < 0.01). FDA showed that glucose was significantly lower midmorn-ing (0900-1100 h) and early evening (1900-2130 h) in trimester 1, significantly higher early morning (0330-0630 h) and throughout the afternoon (1130-1700 h) in trimester 2, and significantly higher during the evening (2030-2330 h) in trimester 3 in women whose infants were LGA. CONCLUSIONS FDA of CGM data identified specific times of day that maternal glucose excursions were associated with LGA. It highlights trimester-specific differences, allowing treatment to be targeted to gestational glucose patterns. [ABSTRACT FROM AUTHOR]

OBJECTIVE To evaluate feasibility, safety, and efficacy of overnight closed-loop insulin delivery in free-living youth with type 1 diabetes. RESEARCH DESIGN AND METHODS Overnight closed loop was evaluated at home by 16 pump-treated adolescents with type 1 diabetes aged 12-18 years. Over a 3-week period, overnight insulin delivery was directed by a closed-loop system, and on another 3-week period sensor-augmented therapy was applied. The order of interventions was random. The primary end point was time when adjusted sensor glucose was between 3.9 and 8.0 mmol/L from 2300 to 0700 h. RESULTS Closed loop was constantly applied over at least 4 h on 269 nights (80%); sensor data were collected over at least 4 h on 282 control nights (84%). Closed loop increased time spent with glucose in target by a median 15% (interquartile range 29 to 43; P < 0.001). Mean overnight glucose was reduced by a mean 14 (SD 58) mg/dL (P < 0.001). Time when glucose was <70mg/dL was low in both groups, but nights with glucose <63mg/dL for at least 20min were less frequent during closed loop (10 vs. 17%; P = 0.01). Despite lower total daily insulin doses by a median 2.3 (interquartile range 24.7 to 9.3) units (P = 0.009), overall 24-h glucose was reduced by a mean 9 (SD 41) mg/dL (P = 0.006) during closed loop. CONCLUSIONS Unsupervised home use of overnight closed loop in adolescents with type 1 diabetes is safe and feasible. Glucose control was improved during the day and night with fewer episodes of nocturnal hypoglycemia. [ABSTRACT FROM AUTHOR]

OBJECTIVE--This study evaluated closed-loop insulin delivery with a model predictive control (MPC) algorithm during early (12-16 weeks) and late gestation (28-32 weeks) in pregnant women with type 1 diabetes. RESEARCH DESIGN AND METHODS--Ten women with type 1 diabetes (age 31 years, diabetes duration 19 years, BMI 24.1 kg/m², booking A1C 6.9%) were studied over 24 h during early (14.8 weeks) and late pregnancy (28.0 weeks). A nurse adjusted the basal insulin infusion rate from continuous glucose measurements (CGM), fed into the MPC algorithm every 15 min. Mean glucose and time spent in target (63-140 mg/dL), hyperglycemic (> 140 to ≥ 180 mg/dL), and hypoglycemic (<63 to ≥50 mg/dL) were calculated using plasma and sensor glucose measurements. Linear mixed-effects models were used to compare glucose control during early and late gestation. RESULTS--During closed-loop insulin delivery, median (interquartile range) plasma glucose levels were 117 (100.8-154.8) mg/dL in early and 126 (109.8-140.4) mg/dL in late gestation (P = 0.72). The overnight mean (interquartile range) plasma glucose time in target was 84% (50100%) in early and 100% (94-100%) in late pregnancy (P = 0.09). Overnight mean (interquartile range) time spent hyperglycemic (> 140 mg/dL) was 7% (0-40%) in early and 0% (0-6%) in late pregnancy (P = 0.25) and hypoglycemic (<63 mg/dL) was 0% (0-3%) and 0% (0-0%), respectively (P = 0.18). Postprandial glucose control, glucose variability, insulin infusion rates, and CGM sensor accuracy were no different in early or late pregnancy. CONCLUSIONS--MPC algorithm performance was maintained throughout pregnancy, suggesting that overnight closed-loop insulin delivery could be used safely during pregnancy. More work is needed to achieve optimal postprandial glucose control. [ABSTRACT FROM AUTHOR]

OBJECTIVE -- To implement and evaluate a regional prepregnancy care program in women with type 1 and type 2 diabetes. RESEARCH DESIGN AND METHODS -- Prepregnancy care was promoted among patients and health professionals and delivered across 10 regional maternity units. A prospective cohort study of 680 pregnancies in women with type 1 and type 2 diabetes was performed. Primary outcomes were adverse pregnancy outcome (congenital malformation, stillbirth, or neonatal death), congenital malformation, and indicators of pregnancy preparation (5 mg folic acid, gestational age, and A1C). Comparisons were made with a historical cohort (n = 613 pregnancies) from the same units during 1999-2004. RESULTS -- A total of 181 (27%) women attended, and 499 women (73%) did not attend prepregnancy care. Women with prepregnancy care presented earlier (6.7 vs. 7.7 weeks; P < 0.001), were more likely to take 5 mg preconception folic acid (88.2 vs. 26.7%; P < 0.0001) and had lower A1C levels (A1C 6.9 vs. 7.6%; P < 0.0001). They had fewer adverse pregnancy outcomes (1.3 vs. 7.8%; P < 0.009). Multivariate logistic regression confirmed that in addition to glycemic control, lack of prepregnancy care was independently associated with adverse outcome (odds ratio 0.2 [95% CI 0.05-0.89]; P = 0.03). Compared with 1999-2004, folic acid supplementation increased (40.7 vs. 32.5%; P = 0.006) and congenital malformations decreased (4.3 vs. 7.3%; P = 0.04). CONCLUSIONS -- Regional prepregnancy care was associated with improved pregnancy preparation and reduced risk of adverse pregnancy outcome in type 1 and type 2 diabetes. Prepregnancy care had benefits beyond improved glycemic control and was a stronger predictor of pregnancy outcome than maternal obesity, ethnicity, or social disadvantage. [ABSTRACT FROM AUTHOR]

A gap currently exists between our expectations of tight blood glucose control and the reality of safely achieving it before and during pregnancy. Technological and pharmaceutical advances will not in isolation prevent poor pregnancy outcomes without recognising the social, cultural and behavioural context of the women living with diabetes. Neither will behavioural and/or educational programmes completely overcome the fundamentally disordered metabolic pathways and physiological challenges of pregnancy. Improved integration of the technological, behavioural and educational aspects of diabetes care will pave the way for truly personalized, interdisciplinary diabetes management and ultimately improved pregnancy outcomes for women with diabetes and their infants.

OBJECTIVE -- The objective of this study was to examine the relationship between prepregnancy care, glycemic control, maternal hypoglycemia, and pregnancy outcomes in women with type 1 diabetes. RESEARCH DESIGN AND METHODS -- This was a prospective observational cohort study of women with type 1 diabetes who delivered from 1991 to 2002. Outcome measures were attendance at a clinic for prepregnancy care, maternal HbA[sub 1c] (A1C) throughout pregnancy, maternal severe hypoglycemic episodes, macrosomia, preeclampsia, premature delivery (delivery before 37 weeks), very premature delivery (delivery before 34 weeks), spontaneous abortion, and adverse pregnancy outcome (defined as major malformation, stillbirth, and neonatal death). RESULTS -- There were 290 pregnancies, in which 110 (38%) women had prepregnancy care. The prepregnancy care group contained more primiparous women (54.7 vs. 40.6%; P = 0.021) and fewer smokers (9.4 vs. 28.7%; P < 0.0001). They registered earlier (6.6 vs. 8.3 weeks, P < 0.0001) and had a lower A1C at the initial visit (6.5% vs. 7.6%; P < 0.0001). Adverse pregnancy outcomes and very premature deliveries were significantly lower in women who received prepregnancy care (2.9 vs. 10.2%; P = 0.03 and 5.0 vs. 14.2%; P = 0.02, respectively). In contrast, between groups, there was no difference in A1C after 24 weeks or in the rates of macrosomia, preeclampsia, or maternal severe hypoglycemic episodes. CONCLUSIONS -- Prepregnancy care was associated with improved glycemic control in early pregnancy and significant reductions in adverse pregnancy outcome (malformation, stillbirth, and neonatal death) and very premature delivery. However, prepregnancy care failed to have an impact on glycemic control in later pregnancy or to reduce the risk of macrosomia and preeclampsia. [ABSTRACT FROM AUTHOR]

The authors of the 2019 article on the association of suboptimal nocturnal glucose control with large for gestational age in treated gestational diabetes mellitus respond to comments on it. They state that the effects of insulin in the context of managing the whole pregnancy need to be considered, and that the challenge is in determining the need for additional treatment. The authors note that it is only then that therapy to the glucose profile can be personalized.

The authors present a response to a comment on the study regarding use of insulin pump or multiple daily injections in type 1 diabetes (T1D) pregnancy glycemic outcomes. The authors agree that more data are needed regarding the optimal implementation of insulin pump therapy during T1D. However, owing to some psycho social complexity, the authors claim that it is not practical to collect detailed data on patient-clinician relationship regarding insulin pump usage.

Technological advances in the management of diabetes have been described as a stepping stone in the journey towards a cure. These include continuous glucose monitoring, insulin pumps, computerised mathematical algorithms, and closed-loop artificial pancreas systems. The approaches offer the tantalising promise of near-normal glucose control to people with diabetes. However, as is often the case with human/technological interactions, we have the technology but we do not have all the answers. [Copyright &y& Elsevier]

OBJECTIVE--To assess random venous blood glucose (RBG) measurement at antenatal booking to detect "overt diabetes in pregnancy" (ODIP). RESEARCH DESIGN AND METHODS--A retrospective analysis of regional hospital obstetric data from 2004-2008 was performed. Universal RBG screening was included at booking. Oral glucose tolerance test (OGTT) was administered if RBG >7.0 mmol/L or other indications, e.g., if a 50-g glucose challenge test was >7.7 mmol/L at 26-28 weeks. ODIP was based upon World Health Organization plasma glucose criteria for diabetes. RESULTS--RBG data were collected from 17,852/26,369 (67.7%) pregnancies around the initial antenatal visit; 3,007 women had an OGTT. The receiver operator curve area under the curve for RBG to detect ODIP was 0.86 (0.80-0.92) (assuming women without an OGTT did not have ODIP). CONCLUSIONS--RBG at booking may provide a sufficiently sensitive screening tool for the detection of ODIP. We recommend further studies and comparison with fasting glucose and HbA

AIMS/HYPOTHESIS: Women with diabetes remain at increased risk of adverse pregnancy outcomes associated with poor pregnancy preparation. However, women with type 2 diabetes are less aware of and less likely to access pre-pregnancy care (PPC) compared with women with type 1 diabetes. We developed and evaluated a community-based PPC programme with the aim of improving pregnancy preparation in all women with pregestational diabetes. METHODS: This was a prospective cohort study comparing pregnancy preparation measures before and during/after the PPC intervention in women with pre-existing diabetes from 1 June 2013 to 28 February 2017. The setting was 422 primary care practices and ten National Health Service specialist antenatal diabetes clinics. A multifaceted approach was taken to engage women with diabetes and community healthcare teams. This included identifying and sending PPC information leaflets to all eligible women, electronic preconception care templates, online education modules and resources, and regional meetings and educational events. Key outcomes were preconception folic acid supplementation, maternal HbA1c level, use of potentially harmful medications at conception and gestational age at first presentation, before and during/after the PPC programme. RESULTS: A total of 306 (73%) primary care practices actively participated in the PPC programme. Primary care databases were used to identify 5075 women with diabetes aged 18-45 years. PPC leaflets were provided to 4558 (89.8%) eligible women. There were 842 consecutive pregnancies in women with diabetes: 502 before and 340 during/after the PPC intervention. During/after the PPC intervention, pregnant women with type 2 diabetes were more likely to achieve target HbA1c levels ≤48 mmol/mol (6.5%) (44.4% of women before vs 58.5% of women during/after PPC intervention; p = 0.016) and to take 5 mg folic acid daily (23.5% and 41.8%; p = 0.001). There was an almost threefold improvement in 'optimal' pregnancy preparation in women with type 2 diabetes (5.8% and 15.1%; p = 0.021). Women with type 1 diabetes presented for earlier antenatal care during/after PPC (54.0% vs 67.3% before 8 weeks' gestation; p = 0.003) with no other changes. CONCLUSIONS/INTERPRETATION: A pragmatic community-based PPC programme was associated with clinically relevant improvements in pregnancy preparation in women with type 2 diabetes. To our knowledge, this is the first community-based PPC intervention to improve pregnancy preparation for women with type 2 diabetes.

Type 1 diabetes in pregnancy is associated with higher rates of maternal and infant complications. The complications are associated with maternal hyperglycaemia. Thus, the main goal of treatment for these women is to optimise glycaemic control and thereby improve clinical outcomes for themselves and for their baby. This thesis examines glycaemic control in the mothers and infants of pregnancies affected by type 1 diabetes. I present the first home studies of closed-loop insulin delivery in this population. The aim of these studies was to assess the feasibility, efficacy, and utility of overnight and then day-and-night closed-loop insulin delivery in pregnant women with type 1 diabetes. The overnight study, which examined 16 pregnant women (mean age 34.1 years, HbA1c 6.8%, 14.4 weeks gestation), compared overnight use of the closed-loop system with sensor-augmented pump therapy in a 2x4-week randomised crossover design. We found that closed-loop therapy was associated with a 15% improvement in overnight time spent with target glucose concentration (3.5-7.8 mmol/L; 74.7% during closed-loop use vs 59.5% during sensor-augmented pump therapy use). The day-and night study also examined 16 pregnant women (mean age 32.8 years, HbA1c 8.0%, 16.4 weeks’ gestation) using a 2x4-week randomised crossover design to compare continuous day-and-night use of closed-loop insulin delivery with sensor-augmented pump therapy. This study enrolled a more diverse range of participants than the overnight study, but found that closed-loop therapy was associated with comparable glucose control and significantly less hypoglycaemia than sensor-augmented pump therapy. Chapter 4 examines women’s experiences of using the closed-loop system during pregnancy. While the system was generally well-received by participants, individual interactions and perceptions of the system varied markedly, and often did not align with biomedical measures of glycaemic response. After participation in either crossover study, participants could choose to continue using the technology until delivery (overnight study), or until 6 weeks post-partum (day and night study). Those data are presented in Chapters 2 and 3. The combined data from the women who used the closed-loop system during labour and delivery in either study are presented in Chapter 5. Tight glycaemic control during labour and delivery has traditionally been considered important for reducing rates of neonatal hypoglycaemia. However, despite very tight maternal glycaemic control in the women who used closed-loop insulin delivery, rates of neonatal hypoglycaemia were high. In order to better characterise the relationship between maternal glucose control in type 1 diabetes pregnancy and neonatal hypoglycaemia, Chapter 6 details an observational study in which continuous glucose monitoring was used to measure maternal and neonatal glycaemic control in 16 mother-infant pairs. The study found that, while neonatal hypoglycaemia was very frequent, it was generally, but not always, detected and treated effectively. Together, these studies suggest that a novel management tool, closed-loop insulin delivery, can improve overnight glycaemic control, and perhaps reduce hypoglycaemia during type 1 diabetes-affected pregnancies above what is possible with currently available treatments. However, complication rates remain high for these women and their babies. Further research is needed both to further develop treatments that can improve maternal glycaemic control, and to better understand the pathogenesis of diabetes-related pregnancy complications, with the ultimate goal of improving outcomes for women and their children. A definitive trial to assess the clinical efficacy, patient acceptability, and cost effectiveness of closed-loop is now warranted.

DIGESTION , *PREGNANT women , *GESTATIONAL diabetes - Abstract
Background: Obesity is a risk factor for gestational diabetes (gestational diabetes). Low-glycemic index diets attenuate hyperglycemia. We designed a study to determine whether a slow-digesting, low-glycemic load (SD-LGL) beverage improves glucose tolerance in obese pregnant women without GDM.Methods: This was a 3-arm comparison study comparing the effects of an SD-LGL nutritional beverage (glycemic load [GL] 730), an isocaloric control beverage (GL 1124), and habitual diet on glycemia in obese pregnant women. Sixteen women (mean body mass index 37 kg/m2) were recruited at 24-28 weeks to receive either the SD-LGL or eucaloric control beverage. This was consumed with breakfast and as a midafternoon snack over 2 days with a controlled diet. Following a 2-day washout period of habitual diet, women completed 2 days on the alternative beverage with controlled diet. A 10-h fast preceded each intervention phase. Twenty-four hour glucose was measured using continuous glucose monitoring.Results: Consumption of the lower GL beverage was associated with improved measures of glycemia, compared with the control beverage and habitual diet at different time periods. Glucose estimates for control versus SD-LDL at 24 h (0.23 mmol/L [0.16 to 0.31], P < 0.001), daytime (0.26 mmol/L [0.18 to 0.34], P < 0.001), and nighttime (0.05 mmol/L [-0.01 to 0.11], P = 0.09). Postprandial glucose was lower after breakfast but not after dinner, compared with the control beverage (0.09 mmol/L [0.01 to 0.18], P = 0.03).Conclusion: A slow-digesting, low-glycemic nutritional beverage may facilitate improved glucose control in obese pregnant women. To address potential benefit for clinical outcomes, a randomized controlled trial is warranted. [ABSTRACT FROM AUTHOR]- Published

PREGNANCY in diabetic women , *BLOOD sugar monitoring , *TYPE 1 diabetes - Abstract
Tight glucose control during labor and delivery is recommended for pregnant women with type 1 diabetes. This can be challenging to achieve using the current treatment modalities. The automated nature of closed loop and its ability to adapt to real-time glucose levels make it well suited for use during labor, delivery, and the immediate postpartum period. We report observational data of participants from two randomized crossover trials who chose to continue using closed loop during labor, delivery, and postpartum. Labor was defined as the 24 h before delivery and postpartum as the 48 h after delivery. The glucose target range during pregnancy was 3.5-7.8 mmol/L (63-140 mg/dL) and 3.9-10 mmol/L (70-180 mg/dL) after delivery. Twenty-seven (84.4%) of the potential 32 trial participants used closed loop through labor, delivery, and postpartum. Use of closed loop was associated with 82.0% (interquartile range [IQR] 49.3, 93.0) time-in-target range during labor and delivery and a mean glucose of 6.9 ± 1.4 mmol/L (124 ± 25 mg/dL). Closed loop performed well throughout vaginal, elective, and emergency cesarean section deliveries. Postpartum, women spent 83.3% (IQR 75.2, 94.6) time-in-target range (3.9-10.0 mmol/L [70-180 mg/dL]), with a mean glucose of 7.2 ± 1.4 mmol/L (130 ± 25 mg/dL). There was no difference in maternal glucose concentration between mothers of infants with and without neonatal hypoglycemia (6.9 ± 1.6 mmol/L and 6.8 ± 1.1 mmol/L [124 ± 29 mg/dL and 122 ± 20 mg/dL] respectively; P = 0.84). Automated closed-loop insulin delivery is feasible during hospital admissions for labor, delivery, and postpartum. Larger scale studies are needed to evaluate its efficacy compared with current clinical approaches as well as understand how women and healthcare providers will adopt this technology.

Aims We developed a new clinical integrated pathway linking a regional Ambulance Trust with a severe hypoglycaemia (SH) prevention team. We present clinical data from the first 2000 emergency calls taken through this new clinical pathway in the East of England. Methods SH patients attended by Ambulance crew receive written information on SH avoidance, and are contacted for further education through a new regional SH prevention team. All patients are contacted unless they actively decline. Results Median age (IQR) was 67 (50–80) years, 23.6% of calls were for patients over 80 years old, and patients more than 90 years old were more common than 20–25 year olds in this population. Most calls were for patients (84.9%) who were insulin treated, even those over 80 years (75%). One - third of patients attended after a call were unconscious on attendance. 5.6% of patients in this call population had 3 or more ambulance call outs, and they generated 17.6% of all calls. In total, 728 episodes (36.4%) were repeat calls. Insulin related events were clinically more severe than oral hypoglycaemic related events. Patients conveyed to hospitals (13.8%) were significantly older, with poorer recovery in biochemical hypoglycaemia after ambulance crew attendance. Only 19 (1%) opted out of further contact. Patients were contacted by the SH prevention team after a median 3 (0–6) days. The most common patient self - reported cause for their SH episode was related to perceived errors in insulin management (31.4%). Conclusions This new clinical service is simple, acceptable to patients, and a translatable model for prevention of recurrent SH in this largely elderly insulin treated SH population.
