Metformin is a commonly used drug in the treatment of type 2 diabetes and has been used to treat gestational diabetes since the 1970s. In pregnancy, its proven benefits include reduced gestational weight gain and reduced fetal size; some studies have shown reduced risk of cesarean delivery and lower rates of hypertension. Metformin can reduce the need for insulin therapy but does not eliminate such need in many patients.

Background: Adopting the WHO protocol for glucose analysis is arguably impractical in the routine clinical setting. Deviations may develop due to a lack of understanding regarding the impact of glycolysis on the accuracy of results.

Aim: We sought to assess the stability of glucose in two different blood collection tubes (BCT), BD Vacutainer® FX 'Fl-Ox' and Greiner Vacuette® FC-Mix 'FC-Mix' stored at room temperature (RT:18-22°C) and 4°C over 8.

Metformin is used worldwide in the treatment of type 2 diabetes and has been used in the treatment of diabetes in pregnancy since the 1970s. It is highly acceptable to patients due to its ease of administration, cost and adverse effect profile. It is effective in reducing macrosomia, large-for-gestational-age infants and reduces maternal weight gain.

Article Synopsis
  • The study investigates the potential of plasma glycated CD59 (pGCD59) as a biomarker to predict postpartum glucose intolerance in women who had gestational diabetes.
  • Postpartum pGCD59 levels were significantly higher in women with glucose intolerance compared to those with normal levels, and it showed good predictive ability with an area under the curve (AUC) of 0.80.
  • However, while pGCD59 may help identify women who do not need traditional glucose intolerance screening, fasting plasma glucose tests demonstrated even better diagnostic accuracy.

Introduction: Pregestational diabetes (PGDM) is an increasingly common and complex condition that infers risk to both mother and infant. To prevent serious morbidity, strict glycaemic control is essential. The aim of this review is to review the glucose sensing and insulin delivering technologies currently available for women with PGDM.

Introduction: Type 1 diabetes mellitus occurs in one in every 275 pregnancies and can result in increased morbidity and mortality for both mother and baby. Several pregnancy complications can be reduced or prevented by attendance at pre-pregnancy care (PPC). Despite this, less than 40% of pregnant women with pre-gestational diabetes receive formal PPC.

Aim: Even though most pregnancies are uneventful, occasionally complications do occur. Gestational diabetes is linked to an increased risk of adverse pregnancy outcomes. Early identification of women at risk of experiencing adverse outcomes, ideally through a single blood test, would facilitate early intervention.

Article Synopsis
  • This study analyzed how pregnancy affects lab test results, aiming to create trimester-specific reference intervals (RIs) for healthy white European women during their pregnancies.
  • A total of 124 healthy participants were included, with strict inclusion criteria ensuring they were without previous health issues and at a normal BMI.
  • The results will help healthcare providers interpret lab tests more accurately throughout the different stages of pregnancy, improving patient care based on trimester-specific data.

Article Synopsis
  • Neonatal hypoglycaemia (NH) is a common issue in infants of mothers with gestational diabetes, and this study explores the link between maternal early pregnancy levels of plasma glycated CD59 (pGCD59) and NH.
  • The research involved 399 pregnant women, examining their pGCD59 levels during a glucose tolerance test, and found that higher maternal pGCD59 levels correlated with an increased risk of NH in their infants.
  • The findings suggest that while pGCD59 is associated with NH, its predictive value diminishes when considering maternal BMI, implying that pGCD59 alone may not be a strong enough predictor for NH in this population.

Aims: To evaluate the ability of first trimester plasma glycated CD59 (pGCD59) to predict gestational diabetes mellitus (GDM) at 24-28 weeks of gestation.

Methods: Prospectively, in 378 pregnant women, GDM was diagnosed using the one step 2 h 75 g oral glucose tolerance test adjudicated by the World Health Organisation (WHO) 2013 criteria. The ability of pGCD59 to predict GDM was assessed using receiver operating characteristic (ROC) curves adjusted for maternal age, body mass index (BMI), maternal ethnicity, parity, previous GDM, family history of diabetes mellitus and week of gestation at time of pGCD59 sampling.

Using genetic scores for fasting plasma glucose (FPG GS) and type 2 diabetes (T2D GS), we investigated whether the fasting, 1-hour and 2-hour glucose thresholds from the WHO 2013 criteria for gestational diabetes (GDM) have different implications for genetic susceptibility to raised fasting glucose and type 2 diabetes in women from the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) and Atlantic Diabetes in Pregnancy (DIP) studies. Cases were divided into three subgroups: (i) FPG ≥5.1 mmol/L only, n=222; (ii) 1-hour glucose post 75 g oral glucose load ≥10 mmol/L only, n=154 (iii) 2-hour glucose ≥8.

Background/objectives: The Institute of Medicine (IOM) recommends gestational weight gain (GWG) of 5-9 kg in women with a body mass index (BMI) ≥ 30 kg/m. Debate continues as to whether GWG less than that recommended is safe in women with gestational diabetes mellitus (GDM). The study objective was to examine maternal and infant outcomes for obese women with GDM who lost weight or gained 0-5 kg during pregnancy.

Core Outcome Sets (COS) contain an agreed minimum set of outcomes to be measured and reported in all studies in a specific area, with the objective of standardizing outcome reporting. COS may minimize research waste by identifying outcomes important to key stakeholders, allowing for improved evidence synthesis, and facilitating translation of research findings to clinical practice. Over the past 5 years, there has been significant progress in developing COS relevant to studies of diabetes in pregnancy.
