Continuous glucose monitoring system in diabetes in pregnancy: a narrative review.

Diabetes in pregnancy increases maternal and fetal risks as well as the burden of chronic complications and comorbidities associated with this condition. In addition to HbA1c and blood glucose monitoring (BGM), continuous glucose monitoring systems (CGM) provide a complementary tool that enables comprehensive glycemic assessments and improves glycemic control. This review highlights the clinical value of CGM in the management of diabetes in pregnancy, encompassing type 1 diabetes, type 2 diabetes, gestational diabetes mellitus (GDM), but also early GDM.

Cardiovascular risk stratification in an ethnically mixed population with type 1 diabetes mellitus: comparison of the Steno Type 1 Risk Engine with the Scottish-Swedish risk model.

Aim: This study compared the performances of the Steno Type 1 Risk Engine (ST1RE) and the Scottish-Swedish risk model in a predominantly young and ethnically diverse type 1 diabetes (T1D) cohort.

Methods: This retrospective study included 435 adults with T1D and no prior cardiovascular disease (CVD). The comparative performance of the models in predicting 10-year CV events was assessed using Kaplan-Meier analysis, ROC curves, the Hosmer-Lemeshow test, and Cohen's kappa coefficient.

Tregs in pregnancy with type 1 diabetes mellitus: pilot study.

Objective: Pregnancy in women with type 1 diabetes mellitus has been associated with adverse outcomes due to persistent hyperglycemia and impaired maternal-fetal interactions. Regulatory T cells seem to exert a critical role in this process. Pregnancy can change the profile of Treg cells and affect the outcome of pregnancy; therefore, our purpose was to characterize the profile of regulatory T cells in the peripheral blood of pregnant and nonpregnant (controls) women with type 1 diabetes mellitus.

Improvements in Insulin Resistance and Glucose Metabolism Related to Breastfeeding Are Not Mediated by Subclinical Inflammation.

Lactation is known to improve insulin resistance, but this phenomenon remains poorly understood. Our goal was to evaluate whether subclinical inflammation could mediate the association between breastfeeding (BF) and improvement in glucose metabolism and markers of insulin resistance (MIRs) in the postpartum. A total of 95 adult women (≥18 years) with a BMI ≥ 25 kg/m from the outpatient clinic of the Federal University of São Paulo were followed from early pregnancy until 60 to 180 days postpartum.

Evaluation of the Steno Type 1 Risk Engine in predicting cardiovascular events in an ethnic mixed population of type 1 diabetes mellitus and its association with chronic microangiopathy complications.

Background: The Steno Type 1 Risk Engine (ST1RE) was developed to aid clinical decisions in primary prevention for individuals with type 1 diabetes (T1D), as existing cardiovascular (CV) risk models for the general population and type 2 diabetes tend to underestimate CV risk in T1D. However, the applicability of ST1RE in different populations remains uncertain, as prediction models developed for one population may not accurately estimate risk in another. This study aimed to evaluate the performance of the ST1RE in predicting CV events among ethnically mixed T1D individuals and its association with the progression of microangiopathy complications.

Association between neck circumference and glucose tolerance levels at 2-6 months postpartum in women with and without gestational diabetes.

Objective: To evaluate the association between neck circumference (NC) measured during pregnancy and markers of glucose metabolism measured 2-6 months postpartum in women with overweight/obesity with and without gestational diabetes (GDM).

Subjects And Methods: This prospective study enrolled 100 pregnant women (including 50 with GDM) with pregestational body mass index (BMI) ≥ 25 kg and < 40 kg/m². The cohort was stratified according to NC tertiles during pregnancy.

Telephone lifestyle intervention to prevent diabetes in women with recent gestational diabetes mellitus attending the national health system: the LINDA-Brasil clinical trial.

Objectives: To evaluate a postpartum telephone-based lifestyle intervention to prevent diabetes in high-risk women with recent gestational diabetes mellitus (GDM).

Design: Multicentre parallel randomised clinical trial.

Setting: Specialised antenatal clinics in the Brazilian National System.

Prolactin does not seem to mediate the improvement on insulin resistance markers and blood glucose levels related to breastfeeding.

Introduction: The prevalence of type 2 diabetes mellitus (T2DM) is increasing worldwide. Strategies to decrease this risk should be strongly encouraged. Lactation has been associated, for the mother, with reduction in future T2DM risk in several studies.

Maternal-fetal outcomes of pregnant women with type 1 diabetes treated with continuous subcutaneous insulin infusion or multiple daily injections during pregnancy - A Brazilian health care referral center cohort study.

Objective: Pregnant women with type 1 diabetes (T1D) have an increased risk of maternal-fetal complications. Regarding treatment, continuous subcutaneous insulin infusion (CSII) has advantages compared to multiple daily injections (MDI), but data about the best option during pregnancy are limited. This study's aim was to compare maternal-fetal outcomes among T1D patients treated with CSII or MDI during pregnancy.

Prediction of lung maturity through quantitative ultrasound analysis of fetal lung texture in women with diabetes during pregnancy.

Objectives: The present study aimed to evaluate the performance of QuantusFLM software, which performs quantitative ultrasound analysis of fetal lung texture, in predicting lung maturity in fetuses of diabetic mothers.

Methods: The patients included in this study were between 34 and 38 weeks and 6 days gestation and were divided into two groups: (1) patients with diabetes on medication and (2) control. The ultrasound images were performed up to 48 h prior to delivery and analyzed using QuantusFLM software, which classified each fetus as high or low risk for neonatal respiratory morbidity based on lung maturity or immaturity.

The gut microbiome of obese postpartum women with and without previous gestational diabetes mellitus and the gut microbiota of their babies.

Background: The incidence of gestational diabetes mellitus (GDM) is increasing worldwide, and has been associated with some changes in the gut microbiota. Studies have shown that the maternal gut microbiota pattern with hyperglycemia can be transmitted to the offspring. The study aimed to evaluate the gut microbiota of obese postpartum women with and without previous GDM and their offspring.

Inadequate pregnancy planning in diabetics, and its impact on glycemic control and complications.

Introduction: To assess the intention of actual pregnancy and its influence on glycated hemoglobin (HbA1c) profile before and during the pregnancy of women with previous diabetes mellitus (DM).

Methods: Prospective cohort study included pregnant women with previous DM assisted from October/2018 to October/2019. Data were collected with standardized questionnaire and from medical records.

Neck circumference as a predictor of gestational diabetes and risk of adverse outcomes in pregnancy of Brazilian woman with overweight and obesity.

Objective: To evaluate the association of neck circumference (NC) with gestational diabetes (GDM) and adverse outcomes in women with overweight and obesity.

Subjects And Methods: This prospective study included 132 (BMI > 25 kg/m) pregnant women without and with GDM. Standardized questionnaire and biochemical/physical evaluation were performed during the 1 to 3 trimester.

Gut microbiota and gestational Diabetes Mellitus: A systematic review.

Background: Gestational Diabetes Mellitus (GDM) is one of the most prevalent complications of pregnancy and can cause adverse maternal and fetal outcomes. The maternal gut microbiota is involved in several metabolic functions, but it is not yet known its role in GDM physiopathology. This study aims to review the role of gut microbiota in pregnancies that evolved with GDM.

The first series of cases of ketosis-prone type 2 diabetes (flatbush diabetes) in Brazilian adults.

Ketosis-prone type 2 diabetes (KPD) is an emerging form of diabetes mellitus characterized by unprovoked ketoacidosis, absence of autoimmunity and beta-cell dysfunction. The KPD may improve after initial glycemic compensation and evolve to exogenous insulin independence, most cases were observed in populations with African or Hispanic backgrounds. We reviewed the literature on KPD and, to date, only one case of KPD has been described in Brazil's multi-ethnic population.
