Increasing proportions of patients with diabetes use continuous subcutaneous insulin infusion (CSII) therapy mostly due to its clinical efficacy and flexibility for insulin dosing and adjustments. Some challenges are nevertheless associated with this technology. A key and underlooked component of CSII technical difficulties is the subcutaneous catheter used to infuse insulin.

Background: During pregnancy, maternal circulating leptin is released by maternal adipose tissue and the placenta, and may have a role in fetal development.

Objectives: We investigated maternal leptinemia and glycemia associations with neonatal adiposity, taking into account pregravid weight status.

Methods: We included 235 pregnant women from the Genetics of Glucose Regulation in Gestation and Growth prospective cohort with data: blood samples collected during the 2nd trimester, an oral glucose tolerance test (OGTT), and the measured leptin and glucose levels.

Objective: Excessive gestational weight gain (GWG) is associated with increased birth weight and neonatal adiposity. However, timing of excessive GWG may have a differential impact on birth outcomes. The objective of this study was to compare the effect of early and mid/late excessive GWG on newborn anthropometry in the context of the Canadian clinical recommendations that are specific for first trimester and for second/third trimesters based on maternal pre-pregnancy BMI.

Purpose: We initiated the Genetics of Glucose regulation in Gestation and Growth (Gen3G) prospective cohort to increase our understanding of biological, environmental and genetic determinants of glucose regulation during pregnancy and their impact on fetal development.

Participants: Between January 2010 and June 2013, we invited pregnant women aged ≥ 18 years old who visited the blood sampling in pregnancy clinic in Sherbrooke for their first trimester clinical blood samples: 1034 women accepted to participate in our cohort study.

Findings To Date: At first and second trimester, we collected demographics and lifestyle questionnaires, anthropometry measures (including fat and lean mass estimated using bioimpedance), blood pressure, and blood samples.

Hypertensive disorders of pregnancy (HDP) lead to high rates of maternal and fetal morbidity. Existing studies on inflammatory marker TNFα in HDP offspring are inconsistent. We performed a population-based cohort study of 636 pregnancies, including normotensive (NT) women and women with preeclampsia (PE) or gestational hypertension (GH).

Acetylcholine (Ach) has vasodilatory actions. However, data are conflicting about the role of Ach in regulating blood flow in subcutaneous adipose tissue (ATBF). This may be related to inaccurate ATBF recording or to the responder/nonresponder (R/NR) phenomenon.

Article Synopsis
  • The Sherbrooke GDM Regional Committee recommended first-trimester screening for gestational diabetes using a 50 g glucose challenge test followed by home blood glucose monitoring.
  • An analysis of 7,710 pregnant women revealed that only 47% were screened in the first trimester, with 5.7% referred to a diabetes care center, and early GDM was identified mainly among those with fewer risk factors.
  • While the implementation of the screening process was effective, the need for ongoing emphasis on early GDM detection and second-trimester rescreening remains crucial.

Objective: The lifetime risk of metabolic diseases in offspring of women with gestational diabetes mellitus (GDM) depends, at least in part, on the impact of glycemic fetal programming. To quantify this impact, we have developed and validated a unique mass spectrometry method to measure the percentage of glycated hemoglobin in cord blood.

Research Design And Methods: This case-control study includes 37 GDM women and 30 pregnant women with normal glucose tolerance (NGT).

The progressive increase of insulin resistance observed in pregnancy contributes to the pathophysiology of gestational diabetes mellitus (GDM). There is controversy whether vitamin D deficiency contributes to abnormal glycemic regulation in pregnancy. We tested the associations between first trimester 25-hydroxyvitamin D (25OHD) levels and: 1) the risk of developing GDM; 2) insulin resistance/sensitivity, beta cell function and compensation indices in a large population-based prospective cohort of pregnant women.

Introduction: TNFα is suspected to play a role in inflammation and insulin resistance leading to higher risk of metabolic impairment. Controversies exist concerning the role of TNFα in gestational insulin resistance. We investigated the interrelations between TNFα and insulin resistance in a large population-based cohort of pregnant women.

Adipose tissue (AT) is a very active organ, both metabolically and hormonally. These important functions depend on adequate blood flow (BF). Metabolic, hormonal, and vascular processes within AT are highly interconnected and any disruption will invariably impact the others.

Objective: The use of a weight-based nomogram is considered as standard care for prescribing appropriate doses of unfractionated heparin (UFH). Because of the need for multiple other medications that may affect bleeding and that clinical data have relied on similar dosing algorithms, maximum initial bolus and infusion rates have been suggested (capped initial dose). Whether these weight-based heparin nomograms properly address therapeutic dosing in obese patients remains questionable.

Objective: To evaluate (1) the effect on gestational diabetes mellitus (GDM) screening rates of having a specialized clinic for pregnant women offering blood sampling and screening for GDM, and (2) the impact on perinatal outcomes of having early GDM screening and follow-up provided by the specialized clinic.

Methods: We performed a retrospective cohort study, based on electronic health records. We compared data from women who delivered during a period when the Blood Sampling in Pregnancy (BSP) clinic was operating (2008-2009; n = 2780) to a time period before the clinic was established (2006-2007; n = 2591).
